Abstract
BACKGROUND Intraoperative radiation therapy (IORT) is a highly conformal type of radiation therapy given at time of surgery aiming for better tumor local control. It increases the tumor radiation dose without exceeding normal tissues tolerance doses. PURPOSE To assess the feasibility of IORT and short-term toxicities in patients with different cancer sites treated with multidisciplinary protocol including IORT. PATIENTS AND METHODS Medical records of cancer patients who received IORT as a part of their multidisciplinary treatment at King Faisal Specialized Hospital and Research center (KFSH&RC), Riyadh, Saudi Arabia, from January 2013 until December 2017 were retrospectively reviewed. RESULTS A total of 188 patients with 210 IORT applications were analyzed. Twenty-two patients had two applications at the same time. One hundred sixteen patients were males. Median age at time of diagnosis was 49.5 years (19-77). One hundred thirty-four patients had primary, while 54 cases had recurrent disease. Gastroesophageal cancer and soft tissue sarcoma were the most frequent diagnosis in 49 patients followed by colorectal cancer in 35 patients. Major surgeries with curative intent done in 183 patients (97.3%). Hyperthermic intraperitoneal chemotherapy (HIPEC) was performed in 118 (62.8%) patients. The 30-day postoperative mortality rate was 3.2%. Fifty-four (28.7%) patients develop grades III-IV complications according to Clavien-Dindo grading system. CONCLUSION The data presented discusses using of IORT treatment for different malignant tumors as a part of multimodality treatment. IORT seems safe and feasible; however, a longer follow-up period is needed for proper evaluation and to define the role of IORT in a tailored multimodality approach.

Feasibility of combining oncology surgery with bariatric surgery; a two-patient case series of sleeve gastrectomy with cytoreductive surgery and HIPEC. J Surg Case Rep 2022; 2022:rjab588. [PMID: 35047173 PMCID: PMC8763604 DOI: 10.1093/jscr/rjab588] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2021] [Accepted: 12/03/2021] [Indexed: 02/05/2023] Open
Abstract
Patients with an oncologic disease requiring cytoreductive surgery and hyperthermic intraperitoneal chemotherapy may also present with morbid obesity. In some patients, it may be possible to offer bariatric surgery such as sleeve gastrectomy in combination with their cancer resection to treat both diseases concurrently. Two such cases are described where sleeve gastrectomy was done alongside the primary oncologic surgery in the same procedure. Our patients had long-term follow-ups and their overall outcomes were favorable. They achieved remission and acceptable levels of weight loss over their several years of follow-up appointments. The added benefit of bariatric surgery may decrease long-term morbidity and mortality in carefully selected patients. More studies are indicated to fully understand the risks of benefits of this combined procedure in order to offer it on a wider scale.

Abstract
Appendiceal mucinous adenocarcinoma is a term that was given for invasive appendiceal tumors. It is always present with pseudomyxoma peritonei which is a complex disease. These tumors have the tendency to surround the primary tumor then extend primarily and extensively all over the peritoneal cavity as the primary site of metastases. The invasion through the abdominal wall muscles is rare but the penetration and passing through these muscles to the subcutaneous tissue are extremely rare. A 62-year-old male patient known to have pseudomyxoma peritonei presented with gluteal abscess. After 2 weeks from the abscess drainage, the patient underwent cytoreductive surgery (CRS) combined with intraoperative radiotherapy (IORT) and hyperthermic intraperitoneal chemotherapy (HIPEC). He tolerated the operation well and discharged home in a good condition. Even with extensive appendiceal mucinous neoplasms presented with the penetration of the abdominal wall muscles, still aggressive management should be considered.

Abstract
BACKGROUND Pancreatic cancer is leading cause of cancer related deaths. The prognosis is usually very poor. In spite of the advances in modern surgery, the outcome is still poor. IORT was recently introduced with recorded improvement in both locoregional tumor control and patient survival. Prophylactic HIPEC was introduced during the initial surgery in order to prevent subsequent peritoneal cancer or tumor recurrence which showed some encouraging results. AIM OF WORK Evaluation of the perioperative results of the combination of IORT and HIPEC with CRS as a novel approach in the management of resectable pancreatic cancer. PATIENTS AND METHODS This study was conducted at King Faisal Specialist Hospital and Research Center, Riyadh, Kingdom of Saudi Arabia. Data were collected retrospectively. A total of five patients were included in the study, during the period from November 2017 to August 2018. All surgeries were done by the same surgeon. RESULTS The average age was 51 years (25-63). The patients were two males and three females. All the patients underwent complete surgical resection combined with IORT then HIPEC. All patients were discharged home in good condition. They were regularly followed up without any evidence of local recurrence or metastases. CONCLUSION The combination of IORT and HIPEC with CRS gives the addition of the benefits of each procedure alone without affecting the postoperative morbidity or mortality. This combination appeared to be feasible, safe and well tolerated. However, this need to be applied on a larger number of patients with longer periods of follow-up to reach sound conclusions.

Abstract
BACKGROUND Gastric cancer can metastasize to multiple organs but the metastases to brain is very rare. We report a case of recurrent gastric cancer. The only site of recurrence is brain metastases that occurred three years after curative resection. CASE PRESENTATION A 58-year-old male patient who was diagnosed to have gastric cancer. He received neoadjuvant chemotherapy then complete resection. The patient came to the outpatient clinic for regular follow up. After three years from resection the patient complained of headache and seizures. CT scan brain showed right temporal bone localized tumor. Complete resection was done which revealed it is a localized metastases from gastric cancer. CONCLUSION Localized brain metastases from gastric cancer is a rare event. Urgent CT scan must be done if the patient had any neurological complaint. Early diagnosis is the key for the patient management. Rapid treatment can improve the patient general condition and neurological manifestations.

Abstract
BACKGROUND In spite of the advances in modern surgery, the outcome for patients suffering from pancreatic adenocarcinoma or periampullary adenocarcinoma is still bad. Recently, introperative radiotherapy (IORT) was introduced into the multimodality management approach to improve both tumor control and patient' survival. AIM OF WORK To evaluate our initial experience in combined surgical resection and IORT, and to evaluate the feasibility of the application of IORT and its effect on morbidity, mortality and local recurrence. PATIENTS AND METHODS This study was conducted at King Faisal Specialist Hospital and Research Center, Riyadh, Kingdom of Saudi Arabia. Data were collected retrospectively. A total of six patients were included in the study, during the period from November 2013 to April 2017. All surgeries were done by the same surgeon. RESULTS The average age was 60 years (50-71). The patients were four males and two females. Five patients underwent complete surgical resection (pancreaticoduodenectomy) combined with IORT. One patient had locally advanced pancreatic tumor which was beyond surgical resection, for whom surgical bypass was done to overcome the biliary obstruction combined with IORT. Two patients died from disease progression and liver metastases. The remaining four patients survived without any evidence of local recurrence or metastases on follow-up. CONCLUSION Application of IORT is safe and feasible. It can be applied without additional morbidities or mortalities. Although our results are satisfactory, yet they need to be applied on a larger number of patients with longer periods of follow-up to reach sound conclusions.

Abstract
INTRODUCTION Cytopenia after hyperthermic intraperitoneal chemotherapy (HIPEC) with cytoreductive surgery (CRS) has been reported in non-comparative studies with various chemotherapeutic regimens. This study compared the incidence of leukopenia and thrombocytopenia in patients who underwent CRS/HIPEC and received melphalan or cisplatin plus mitomycin-c (CIS + MMC). METHODS This retrospective study included patients who underwent CRS/HIPEC at King Faisal Specialist Hospital and Research Centre, Riyadh, Saudi Arabia from March 2011 to March 2017 and received melphalan 60 mg/m2 or CIS 100 mg/m2 combined with MMC 30 mg/m2. Incidences and severity of leukopenia, neutropenia, thrombocytopenia, and anemia were compared between groups. RESULTS This study included 46 patients who received CIS + MMC and 35 patients who received melphalan. The leukopenia incidence was 25.7% in the melphalan group and 17.3% in the CIS + MMC group (P = 0.362), with one patient (2.8%) in the melphalan group developed grade V leukopenia. The number of days to leukocyte nadir was 32.8 days for CIS + MMC group compared to 9.8 days for melphalan group(P = 0.035). Thrombocytopenia occurred at a similar rate in the melphalan (60%) and CIS + MMC (68.8%) groups (P = 0.4). Grade III thrombocytopenia developed in 3.2% and 5% of patients in the melphalan and the CIS + MMC groups, respectively. Neutropenia did not occur in any patient. In multivariate analysis, leukopenia predictors were female gender (P = 0.047) and baseline leukocyte counts (P = 0.029). Baseline platelet count predicted thrombocytopenia (P < 0.001). CONCLUSIONS Melphalan and CIS + MMC regimens were associated with comparable incidences of leukopenia and thrombocytopenia. Severe leukopenia and severe thrombocytopenia were rare following CRS/HIPEC using both chemotherapy regimens.

Abstract
INTRODUCTION Persistent Müllerian Duct Syndrome (PMDS) is a rare sexual disease. It is characterized by the presence of female reproductive structures such as uterus, cervix, fallopian tubes and upper part of vagina in a normal genotypically and phenotypically male. The diagnosis is usually incidental since the patients will present with normal external genitalia and secondary sexual characteristics. Imaging techniques such as magnetic resonance imaging (MRI), computed tomography (CT) scan, or ultrasound (US) could help in the diagnosis. CASE PRESENTATION A 45-year-old male presented with bilateral undescended testes since birth and 2 months history abdominal mass. CT scan showed a 13 × 17 × 20 cm solid pelvi-abdominal mass. The diagnosis of mixed germ cell tumor of the undescended testes was made based on the CT scan. During resection of the tumor, patient was found to have a uterus, fallopian tubes and ovaries. DISCUSSION Pathological investigation showed endometrial tissues with portion of lower uterine segment and cervix with remnant of testes with marked atrophy. No Ovarian tissues were found nor fallopian tube as well. The diagnosis of PMDS was made based on the pathological report. CONCLUSION PMDS is a challenging condition to diagnose. Radiological investigation can miss the presence of the Müllerian duct structures as in our case because of the unusual presentation of this condition. Early diagnosis and management is important as the malignant transformation is high due to the undescended testes.

Abstract
Nasogastric tubes (NGTs) are important for feeding, stenting and decompression after gastrointestinal surgeries, particularly in the upper gastrointestinal tract. Resistance in the removal of a NGT is a rare surgical complication and may be due to a knot in the tube or a stitch anchoring the tube to an anastomosis. We report a 41-year-old male patient who was admitted to the King Faisal Specialist Hospital & Research Center, Riyadh, Saudi Arabia, in 2015 with stomach cancer. He underwent a radical total gastrectomy with a Roux-en-Y oesophagojejunostomy. One week after the surgery, removal of the NGT was attempted; however, this was very difficult and the proximal end of the tube was cut off as a temporary measure. Six weeks later, an upper gastrointestinal tract endoscopy revealed that the distal end of the NGT had been accidentally stitched to the Roux-en-Y oesophagojejunostomy. The stitch was removed and the rest of the NGT was successfully extracted using a snare.

Abstract
BACKGROUND AND AIMS Pseudomyxoma peritonei (PMP) results from perforated appendiceal tumors. It is usually diagnosed preoperatively by imaging. Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC), although aggressive long procedure with high complications rate, was considered the optimal treatment. This study is aiming to study the role of CRS and HIPEC in the management of PMP and assess the outcome. METHODS This is a retrospective study which was conducted at King Faisal Hospital and Research Center, a tertiary care hospital during the period from November 2008 to June 2016. Approval of the Research Advisory Council was obtained. Forty-one procedures of CRS and HIPEC were performed in 38 patients. Using the open abdomen technique, CRS was performed using standard peritonectomy procedures and visceral resections directed toward the complete elimination of tumors from abdominopelvic cavity. HIPEC was performed using mitomycin C in a dose of 30 mg/m2 and allowed to circulate in abdominopelvic cavity for 90 min at 41.0 to 42.2 °C. RESULTS Forty-one procedures were performed in 38 patients. Three procedures were done as repeat CRS and HIPEC. No perioperative mortality. Cystoscopy and bilateral ureteric stents in 35 procedures (85.5%). Hospital stay (range 9-85 days) average is 21 days. Follow up period is 1-84 months, and median follow up is 54 months. Five-year survival rate is 92%. Median 5-year disease-free survival rate is 60%. Two patients died during the follow up period by septic shock and one patient died from disease progression. CONCLUSION CRS and HIPEC is well-tolerated and feasible management for PMP.

Abstract
BACKGROUND Hyperglycemia is a major complication of parenteral nutrition (PN). Guidelines for hyperglycemia management in noncritically ill patients cite basal insulin administration but do not recommend a regimen. The GLUCOSE-in-PN study aimed to compare the efficacy of glargine insulin versus continuously infused regular insulin in PN (RI-in-PN) to achieve glycemic control in noncritically ill surgical patients with diabetes who were receiving PN. METHODS This prospective randomized open-label study was conducted at King Faisal Specialist Hospital and Research Centre. Noncritically ill surgical patients with diabetes who were receiving PN were randomized to receive basal glargine insulin or RI-in-PN on day 4 of PN support. Mean blood glucose levels were compared on study days 5-9. The percentages of blood glucose measurements at goal were compared between groups. RESULTS Sixty-seven PN treatment episodes were analyzed. There were no statistically significant differences in mean glucose levels between groups on any study day ( P > .1). Overall glycemic control rates were 52.24% (glargine insulin) and 47.76% (RI-in-PN; P = .06). A significantly higher percentage of hyperglycemia was observed on day 5 for glargine insulin versus RI-in-PN (22.39% vs 5.97%, P = .0059). Blood glucose measurements indicated 6 hypoglycemic events: 2 for glargine insulin (5.7%) and 4 for RI-in-PN (11.4%; P > .1). CONCLUSION Both glargine insulin and RI-in-PN are effective basal insulin modalities for blood glucose control in noncritically ill surgical patients with diabetes who are receiving PN. Uncontrolled hyperglycemic events occurred more frequently with glargine insulin, and the rate of hypoglycemia was acceptable for both regimens.

Abstract
BACKGROUND AND AIM In living donor liver transplantation (LDLT), biliary complications continue to be the most frequent cause of morbidity and may contribute to mortality of recipients although there are advances in surgical techniques. This study will evaluate retrospectively the short-term and long-term management of biliary complications. METHODS During the period from May 1999, to May 2004, 505 patients underwent 518 LDLT in the Department of Liver Transplantation and Immunology, Kyoto University Hospital, Japan. The data was collected and analyzed retrospectively. RESULTS The recipients were 261 males (50.4%) and 257 females (49.6%). Biliary complications were reported in 202/518 patients (39.0%), included; biliary leakage in 79/518 (15.4%) patients, leakage followed by biloma in 13/518 (2.5%) patients, leakage followed by stricture in 9/518 (1.8%) patients, and biliary strictures in 101/518 (19.3%) patients. Proper management of the biliary complications resulted in a significant (p value 0.002) success rate of 96.5% compared to the failure rate which was 3.5%. CONCLUSION Careful preoperative evaluation and the proper intraoperative techniques in biliary reconstruction decrease biliary complications. Early diagnosis and proper management of biliary complications can decrease their effect on both the patient and the graft survival over the long period of follow up.

Abstract
BACKGROUND Iatrogenic ureteric injury is a rare, yet serious operative complication in gynecologic procedures and associated with substantial morbidities such as prolonged hospitalization, additional financial-based ureter-related repairing procedures, impaired renal function, and compromised quality of life. Direct visual identification of ureters can be very challenging in managing patients with primary advanced or recurrent disseminated intraperitoneal gynecologic malignancies, who are referred to complex procedures such as cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). AIMS To report our single-center experience (feasibility and morbidity) with prophylactic ureteric stents as a routine practice before CRS+HIPEC procedure in managing peritoneal carcinomatosis (PC) from gynecologic malignancies. METHODS From June-2010 to March-2014, all patients with gynecologic-related PC, managed with CRS+HIPEC, and underwent prophylactic ureteric stents. The data were retrospectively abstracted and analyzed. RESULTS Fifty-three patients were identified. Almost all PC cases were secondary/recurrence presentations (90.6 %) and originated from ovarian cancer (84.9 %). Optimal cytoreduction microscopic residual disease) was achieved in 35 patients (60 %). Average insertion time of ureteric stents was 8.9 ± 3.3 min. Fifty-two patients (98.1 %) received bilateral ureteric stents. Forty-nine patients (92.5 %) had their ureteric stents removed by the end of procedure. No patient experienced major peri-operative urinary tract-related complications. CONCLUSIONS Prophylactic ureteric stents appeared to be feasible, potentially safe, and could reduce the risk of iatrogenic ureteric injuries without incurring an increase in urinary tract-related complications. Prophylactic ureteric stenting does not eliminate the necessity for competent anatomical knowledge, meticulous retroperitoneal dissection and direct intra-operative visualization of ureters.

Abstract
INTRODUCTION The reported incidence of incisional hernia following orthotopic liver transplantation (OLT) varies from 4% to 23%. Postoperative wound complications are less frequent after laparoscopic repair while maintaining low recurrence rates. We present our experience in managing this complication. MATERIALS AND METHODS Retrospectively, collected data of all patients who underwent liver transplant and developed incisional hernias were analyzed. Patients' demographic data, anthropometric data, transplantation-related data, and repair-related operative and postoperative data were collected. Risk factors for post-transplant incisional hernia were appraised in our patients. Patients were divided into two groups: Group A included patients who had their incisional hernia repaired through the laparoscopic approach, and Group B included patients who had their incisional hernia repaired through open conventional approach. RESULTS A total of 488 liver transplantations were performed at our institution between May 2001 and end of December 2012. Thirty-three patients developed incisional hernias after primary direct closure of the abdominal wall with an overall incidence of 6.9%. Hernia repair was done in 25 patients. Follow-up ranged from 6.4 to 106.1 months with a mean of 48.3 ± 28.3 months. All patients were living at the end of the follow up except four patients (16%). Group A included 13 patients, and Group B included 12 patients. The size of defects and operative time did not differ significantly between both the groups. On the other hand, hospital stay was significantly shorter in laparoscopic group. Complication rate following laparoscopic repair was insignificantly different for open repair. CONCLUSION In experienced hands, laparoscopic incisional hernia repair in post-liver transplant setting proved to be a safe and feasible alternative to open approach and showed superior outcome expressed in shorter hospital stay, with low recurrence and complication rate.

Cytoreductive Surgery plus Hyperthermic Intraperitoneal Chemotherapy for Management of Peritoneal Sarcomatosis: A Preliminary Single-Center Experience from Saudi Arabia. Gastroenterol Res Pract 2016; 2016:6567473. [PMID: 27212941 PMCID: PMC4860243 DOI: 10.1155/2016/6567473] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/23/2016] [Revised: 03/08/2016] [Accepted: 04/07/2016] [Indexed: 02/05/2023] Open
Abstract
Aim. To report our preliminary single-center experience with cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) for management of peritoneal sarcomatosis (PS). Methods. Eleven patients were retrospectively analyzed for perioperative details. Results. Cytoreduction completeness (CC-0/1) was achieved in all patients with median peritoneal cancer index (PCI) of 14 ± 8.9 (range: 3-29). Combination cisplatin + doxorubicin HIPEC chemotherapy was used in 6 patients. Five patients received intraoperative radiation therapy (IORT). The median operative time, estimated blood loss, and hospital stay were 8 ± 1.4 hours (range: 6-10), 1000 ± 250 mL (range: 700-3850), and 11 ± 2.4 days (range: 7-15), respectively. Major postoperative Clavien-Dindo grade III/IV complications occurred in 1 patient and none developed HIPEC chemotherapy-related toxicities. The median overall survival (OS) and disease-free survival (DFS) after CRS + HIPEC were 28.3 ± 3.2 and 18.0 ± 4.0 months, respectively. The median follow-up time was 12 months (range: 6-33). Univariate analysis of several prognostic factors (age, gender, PS presentation/pathology, CC, PCI, HIPEC chemotherapy, and IORT) did not demonstrate statistically significant differences of OS and DFS. Conclusion. CRS + HIPEC appear to be feasible, safe, and offer survival oncological benefits. However, definitive conclusions cannot be deduced.

Abstract
Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide and has a poor prognosis if untreated. It is ranked the third among the causes of cancer-related death. There are multiple etiologic factors that can lead to HCC. Screening for early HCC is challenging due to the lack of well specific biomarkers. However, early diagnosis through successful screening is very important to provide cure rate. Liver transplantation (LT) did not gain wide acceptance until the mid-1980s, after the effective immunosuppression with cyclosporine became available. Orthotopic LT is the best therapeutic option for early, unresectable HCC. It is limited by both, graft shortage and the need for appropriate patient selection. It provides both, the removal of tumor and the remaining cirrhotic liver. In Milan, a prospective cohort study defined restrictive selection criteria known as Milan criteria (MC) that led to superior survival for transplant patients in comparison with any other previous experience with transplantation or other options for HCC. When transplantation occurs within the established MC, the outcomes are similar to those for nonmalignant liver disease after transplantation. The shortage of organs from deceased donors has led to the problems of long waiting times and dropouts. This has led to the adoption of extended criteria by many centers. Several measures have been taken to solve these problems including prioritization of patients with HCC, use of pretransplant adjuvant treatment, and living donor LT.

Abstract
Gastrointestinal stromal tumors (GISTs) are rare neoplasms of the gastrointestinal (GI) tract. The occurrence of these neoplasms ectopically outside the GI tract is extremely uncommon. Only one case of primary adrenal GIST has been reported in the literature. In this account, we report a second case of primary adrenal GIST in a 34-year-old male who presented with a 5-week history of gradually progressive left flank pain and early satiety. Whole-body positron emission tomography (PET)/computed tomography (CT) scan showed a 14 × 11 cm hypermetabolic (18)fluorodeoxyglucose (FDG)-avid mass lesion involving the left adrenal gland and dorsal part of the left hemi-diaphragm. Biopsy of the lesion revealed tumor cells that are immunoreactive to CD-117 and CD-34 and negative to CD-31, S-100, cytokeratin, desmin, and vimentin, features characteristic of GIST. The patient was given imatinib, which drastically decreased his complaints with almost complete resolution of the tumor on his last follow-up radiographic images. Primary left adrenal GIST is an extremely rare neoplasm and can be confused with GISTs arising from the greater curvature of the stomach. Imatinib therapy is optimal in the management of these tumors.

Abstract
BACKGROUND Cisplatin is commonly used in hyperthermic intraperitoneal chemotherapy (HIPEC) for the management of peritoneal carcinomatosis. Little is known about the nephrotoxic effects of cisplatin use in HIPEC. OBJECTIVES To report the incidence of nephrotoxicity post-HIPEC using cisplatin 50 mg/m(2) plus doxorubicin 15 mg/m(2). The incidence of hypomagnesemia was investigated as a secondary endpoint. METHODS This is a retrospective study evaluating patients who received cisplatin with doxorubicin during HIPEC. RIFLE classification was used to assess the development of nephrotoxicity. Variables, such as comorbidities and nephrotoxic medications were obtained. Renal function parameters were also collected, including serum creatinine levels and serum magnesium levels at baseline and at days 3, 7 and 30 after HIPEC. Perioperative urine output (UO) was also recorded. RESULTS Fifty-three patients were identified. Based on the RIFLE classification, two patients (3.7%) developed acute kidney injury (AKI) following HIPEC with cisplatin. One patient met criteria for renal failure and progressed to chronic renal failure. The other patient had renal injury. Comparable mean creatinine levels were observed at baseline and on day 30 following HIPEC (p > 0.05). The incidence of hypomagnesemia increased to 24.5% by day 7 (p = 0.041) and 30.1% by day 30 (p < 0.001) following HIPEC. Low intraoperative UO, angiotensin II receptor antagonist use and hypertension were associated with development of AKI (p < 0.05). CONCLUSION Nephrotoxicity can complicate HIPEC with cisplatin therapy and that permanent renal dysfunction may rarely occur. More attention to be directed toward monitoring magnesium levels after cisplatin use with HIPEC.

Abstract
VIPoma is an exceedingly unusual neuroendocrine neoplasm that autonomously secretes vasoactive intestinal polypeptide (VIP). Its reported incidence is approximately 1 per 10 million individuals per year. Herein, we report the case of sporadic pancreatic VIPoma in a 47-year-old male who presented with a six-month history of chronic, plentiful, watery diarrhea. On physical examination, the patient looked sick, lethargic and had signs of dehydration. Laboratory investigations revealed high VIP hormone level (989pg/mL), hypokalemia, hypercalcemia, hyperglycemia, high blood urea nitrogen, high creatinine, and metabolic acidosis on arterial blood gas. Contrast-enhanced computed tomography (CT) scan showed a 3.1×3.3×4.7cm, well-defined, enhancing lesion involving the pancreatic tail with a cystic component. Moreover, a 5.7×6.1×6.8cm metastatic hepatic lesion was identified. The patient underwent distal pancreatectomy with splenectomy, hepatic lesion resection, and lymph node dissection. Histopathological and immunohistochemical examination of the pancreatic and hepatic lesions revealed neuroendocrine tumor (VIPoma). Postoperatively, the patient received radiofrequency ablation for the hepatic lesion. A post-operative six-month follow-up showed significant symptomatic relief, reduced VIP hormone level (71pg/mL) and normalized electrolyte and acid-base profiles. However, a magnetic resonance imaging (MRI) scan showed a small residual metastatic liver lesion which was considered for hepatic artery embolization (HAE). The patient is still alive with a residual hepatic disease at 18months. We also present a brief literature review on VIPoma.

Abstract
AIM The aim of this study was to retrospectively report our experience (efficacy/morbidity) with cytoreductive surgery+hyperthermic intraperitoneal chemotherapy (CRS+HIPEC) for the management of recurrent/relapsed ovarian granulosa cell tumors (OGCT). MATERIAL AND METHODS From 2010 to 2013, six patients underwent CRS+HIPEC. CRS was performed with standard peritonectomy procedures and visceral resections directed towards complete elimination of tumors from the abdominopelvic cavity. HIPEC was performed with cisplatin (50 mg/m²) and doxorubicin (15 mg/m²) and allowed to circulate in the abdominopelvic cavity for 90 min at 41.0-42.2°C. RESULTS Cytoreduction completeness (CC-0) was achieved in all except one patient (CC-1). Five patients had OGCT recurrences in abdomen+pelvis and one patient in abdomen only. No grade V morbidity (Clavien-Dindo classification) occurred. Two patients developed lung atelectasis, which was managed by mere chest physiotherapy (grade I). One patient developed urinary tract infection (grade II) and another patient developed pneumonia (grade II) - both of which were managed by antibiotics. One patient developed splenic bed and anterior abdominal wall collections requiring ultrasound-guided aspiration without general anesthesia (grade III). One patient developed pulmonary embolism requiring intensive care-unit management (grade IV). Four chemo-naïve patients received adjuvant chemotherapy whereas the remaining two previously chemo-exposed patients received no adjuvant therapy. All patients were alive and disease-free without proof of recurrence/relapse at 40, 32, 27, 24, 20 and 16 months. The average interval of follow-up after CRS+HIPEC was roughly 27 months (range: 16-40 months). CONCLUSION CRS+HIPEC appears to be an efficacious and morbidly well-tolerated therapeutic modality for recurrent/relapsed OGCT. Long-term follow-up data and further research are needed.

Abstract
CONTEXT Pancreatic arteriovenous malformations (AVMs) are uncommon in the gastrointestinal tract. Less than 100 cases have been identified in the medical literature. Approximately 10% of all pancreatic AVMs are sporadic. CASE REPORT Herein, we report the first documented case of sporadic concurrent pancreatic head and tail AVMs in a 40-year-old gentleman who presented with a 10-day history of epigastric pain and one episode of hematemesis. Patient denied any history of traumatic incidents, cigarette smoking, alcohol abuse, chronic gastric/duodenal ulcer, chronic pancreatitis, chronic hepatic disease, difficulty swallowing, respiratory compromise, or weight loss. Physical examination and laboratory results were unremarkable. Contrast-enhanced computed tomography scan showed two hypervascular masses involving the pancreatic head and tail. The celiac trunk angiogram showed proliferating vascular networks involving the pancreatic head and tail. The superior mesenteric angiogram demonstrated significant vascular contribution to the pancreatic head arteriovenous malformation only. Due to the extreme locations of pancreatic AVMs in the head and tail, surgical resection of both lesions (leaving behind the normal pancreatic body) was not possible. Instead, patient underwent intraoperative irradiation therapy (IORT). During the procedure, patient was surgically operated to retract healthy organs/tissues, and then a single concentrated dose of radiation therapy was precisely applied to both pancreatic head and tail AVM lesions. Patient had an uneventful postoperative recovery and was discharged home on the second postoperative day in stable condition. The patient is to be seen in clinic in a 4-month-period during which patient will be completing a 12-month period of postoperative IORT. CONCLUSION This is the first documented case of sporadic concurrent pancreatic head and tail AVMs. Angiography is the gold standard diagnostic modality.
