Cytoreductive Surgery with Bidirectional Intraoperative Chemotherapy (BDIC) Using Intravenous Ifosfamide Plus Hyperthermic Intraperitoneal Chemotherapy (HIPEC) in Patients with Peritoneal Sarcomatosis: A Retrospective Cohort Study.

BACKGROUND: Peritoneal sarcomatosis (PS) is a rare tumor with limited therapeutic options. Bidirectional intraoperative chemotherapy (BDIC) using intravenous ifosfamide and doxorubicin-based hyperthermic intraperitoneal chemotherapy (HIPEC) after cytoreductive surgery (CRS) is an emerging treatment for peritoneal malignancies. PATIENTS AND METHODS: Patients with PS who underwent CRS/BDIC using intravenous ifosfamide and HIPEC from January 2017 to July 2021 were retrospectively analyzed. The last follow-up date was May 2022. RESULTS: A total of 29 patients were included. Overall survival (OS) rates at 6, 12, 24, and 48 months after CRS/BDIC were 93.1%, 89.2%, 81.4%, and 73.3%, respectively. As of May 2022, 6 patients (20.6%) had died, including four (13.8%) with a proven recurrent tumor and two with incomplete tumor resection [completeness of cytoreduction (CC)-2 or CC-3]. Of the 20 patients (68.9%) with CC-0 or CC-1, 7 had locoregional tumor recurrence without distant metastasis, whereas the other 13 were alive with no evidence of recurrent tumor in May 2022. Disease recurrence rates were 15% at 6 months and 35% at 12, 24, and 48 months after CRS/BDIC. Clavien-Dindo class ≥ IIIa complications developed in 9 patients (31.0%) with no deaths. Leukopenia occurred in 5 patients (17.2%) and thrombocytopenia in 12 patients (41.3%); these hematologic abnormalities resolved. A total of 9 (31.0%) patients developed nephrotoxicity; all recovered except one, who progressed to chronic kidney disease. CONCLUSIONS: CRS/BDIC using intravenous ifosfamide and doxorubicin-based HIPEC is a potentially effective treatment for PS and has an acceptable rate of complications.

Circulating microRNA-301 as a promising diagnostic biomarker of hepatitis C virus-related hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is a serious consequence of persistent hepatitis C virus (HCV) infection and represents one of the most aggressive neoplasms globally. The implication of microRNA-301 (miR-301) in the initiation and progression of different types of cancers has been proved. We aimed to assess circulating microRNA-301 as possible biomarker for the early detection of HCC in patients with chronic HCV infection. miR-301 expression levels were estimated in plasma samples of 42 patients with newly diagnosed HCV-related HCC, 48 chronically HCV infected patients with liver cirrhosis and 40 healthy individuals by reverse transcription-quantitative polymerase chain reaction technique. In comparison with chronically HCV infected patients and healthy controls, miR-301 expression levels were significantly increased in HCC patients (P < 0.001). miR-301 levels distinguished HCC patients from chronic HCV patients, with area under the receiver-operating characteristic curve of 0.89 (95% CI 0.82-0.96), the sensitivity and the specificity were 78.57% and 89.58% respectively. Moreover, miR-301 levels were significantly linked with tumor size (P = 0.014), serum levels of alpha-fetoprotein (AFP) (P = 0.028) and Barcelona Clinic Liver Cancer (BCLC) score (P = 0.003). These results reveal that miR-301 can serve as a promising non-invasive biomarker for diagnosis of HCC in chronically HCV infected patients.

The usefulness of laparoscopic hernia repair in the management of incisional hernia following liver transplantation.

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.

Concurrent pancreatic head and tail arteriovenous malformations in a 40-year-old gentleman: the first published report.

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.

Sporadic insulinoma in a 10-year-old boy: a case report and literature review.

CONTEXT: Insulinoma is an exceedingly uncommon pancreatic islet cell neuroendocrine tumor. Its estimated incidence is approximately four cases per million individuals per year. CASE REPORT: We report the case of sporadic insulinoma in an exceptionally very young 10-year-old boy who presented with a 1-month history of episodic tremulousness, diaphoresis, increased hunger, confusion and fainting. Initial laboratory investigations showed low blood glucose (64 mg/dL) and high blood insulin (6 µU/mL) levels. Patient was admitted in view of frequent hypoglycemic symptoms and possible pancreatic insulinoma. A 48-hour mentored fasting test was done and ceased within 3 hours due to occurrence of hypoglycemic symptoms. During the episode, blood was drawn and results showed low blood glucose level and high insulin, pro-insulin and C-peptide levels. The hypoglycemic symptoms were relieved greatly by glucose administration and Whipple's triad for insulinoma was met. An abdominal contrast-enhanced computed tomography scan showed a 10 x 12 x 17 mm, small, well-demarcated, heterogeneously enhancing lesion within the body of pancreas without dilatation of pancreatic duct. No evidence of lymphadenopathy or distant metastasis was identified. Patient underwent enucleation of pancreatic tumor. Histopathological and immunohistochemical examination of the pancreatic mass confirmed neuroendocrine tumor (insulinoma). Patient had an uneventful recovery. A post-operative 6-month follow-up showed resolution of hypoglycemic symptoms, normalized blood glucose, insulin, pro-insulin and C-peptide levels, and no evidence of recurrence. CONCLUSION: Although rare, sporadic insulinoma should be considered in the differential diagnosis of any young individual presenting with frequent hypoglycemic symptoms (neuroglycopenic and/or autonomic nervous system symptoms). Furthermore, a literature review on insulinoma is presented.

Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for management of recurrent/relapsed ovarian granulosa cell tumor: a single-center experience.

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.

The incidence of cisplatin nephrotoxicity post hyperthermic intraperitoneal chemotherapy (HIPEC) and cytoreductive surgery.

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.

Treatment of recurrent malignant pheochromocytoma with a novel approach: A case report and review of literature.

INTRODUCTION: Pheochromocytomas are rare catecholamine-secreting tumors with a high potential for recurrence post-surgery, necessitating prolonged follow-up. This case highlights the diagnostic and therapeutic challenges in managing recurrent pheochromocytoma. CASE PRESENTATION: A 25-year-old female, with a history of left pheochromocytoma treated with adrenalectomy a decade earlier, presented with a right adrenal mass. Despite controlled hypertension, elevated urine metanephrines suggested recurrence. Imaging showed a right adrenal mass and suspicious left paraaortic lymph nodes, confirming the diagnosis of recurrent malignant pheochromocytoma in the left adrenal bed and right adrenal gland, with metastasis to the paraaortic lymph nodes. The patient underwent right adrenalectomy coupled with cytoreductive surgery (CRS) in the form of excision of left-sided adrenal bed recurrence and left paraaortic lymph node dissection, intraoperative radiation therapy (IORT), and hyperthermic intraperitoneal chemotherapy (HIPEC). On follow-up six years later, the patient remains free from recurrence. DISCUSSION: This case illustrates the importance of continued surveillance in pheochromocytoma patients, even those with a low-risk profile. The recurrence in this case, despite a smaller initial tumor size and no genetic predispositions, underscores the unpredictable nature of pheochromocytomas. The successful management with CRS, IORT, and HIPEC emphasizes the need for a personalized and multifaceted treatment approach. CONCLUSION: Pheochromocytoma patients, including those initially considered low risk, require long-term monitoring due to the risk of recurrence. The utilization of CRS, IORT, and HIPEC in this case was pivotal in managing the recurrent and metastatic malignant disease effectively, demonstrating the significance of a comprehensive, multidisciplinary treatment strategy in such complex cases.

Ancient schwannoma in the right iliac fossa: A case report and review of literature.

Ancient schwannomas are a rare variation of schwannomas, with the distinction being based on histopathological examination of the excised specimen. On histopathological examination, ancient schwannomas exhibit degenerative changes such as calcification, hyalinization, and cystic necrosis, along with S100 positivity. Complete surgical excision is the mainstay treatment for ancient schwannomas and carries a favorable prognosis. Recurrence is the most common complication, often arising from incomplete surgical excision. Herein, we present a case of a 41-year-old male who presented to our center as a case of a retroperitoneal mass for further investigations and diagnostic workup. Imaging showed a retroperitoneal mass in the right iliac fossa. We proceeded with ultrasound guided needle biopsy, and examination of the specimen confirmed the diagnosis of ancient schwannoma. Subsequently, the patient underwent surgery, and complete surgical excision was achieved. On follow-up 3-months later, the patient is doing well, and no signs of recurrence were found.

Cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy and intraoperative radiation therapy in the management of gallbladder cancer: a case report.

Gallbladder cancer (GBC) is a rare and highly aggressive malignancy, often characterized by nonspecific clinical presentations and late diagnosis, which contribute to its poor prognosis. It is commonly detected at advanced stages, leading to low survival rates. Surgical resection is the primary treatment, with the extent of surgery depending on the T stage of the cancer. In advanced cases, surgery is only considered if it can potentially be curative. Despite various treatment approaches for advanced GBC, survival outcomes remain poor. In our case series, we introduce a novel treatment approach combining cytoreductive surgery, intraoperative radiation therapy, and hyperthermic intraperitoneal chemotherapy. Remarkably, we observed a 100% one-year survival rate, with one patient achieving eight years of disease-free survival without recurrence or metastasis. This aggressive treatment strategy did not lead to increased morbidity or mortality, suggesting its safety and feasibility. However, larger-scale studies are required to draw definitive conclusions.

Bidirectional Intraoperative Chemotherapy Using Cisplatin and Ifosfamide for Intraperitoneal Mesothelioma in Severe Renal Impairment: A Case Report.

BACKGROUND Malignant peritoneal mesothelioma (MPM) is an aggressive neoplasm with a poor prognosis. Bidirectional intraoperative chemotherapy (BDIC) using concurrent intraperitoneal and intravenous chemotherapy in combination with cytoreductive surgery (CRS) is an emerging treatment option for selected cases of MPM. It is a locoregional treatment that involves intraoperative chemoperfusion of heated chemotherapy. The administration of systemic along with intraperitoneal chemotherapy allows for a bidirectional chemotherapy gradient in peritoneal tumor cells. The aim of this treatment is eradication of microscopic residual cancer cells after major removal of macroscopic tumor nodules. To date, there is no consensus on the chemotherapeutic regimen that can be used in BDIC to manage MPM in patients with severe renal impairment. Administering intravenous ifosfamide with hyperthermic intraperitoneal cisplatin and doxorubicin is a promising regimen in treating peritoneal mesothelioma. Nephrotoxicity is a dose-limiting adverse effect of cisplatin and ifosfamide. Therefore, dose adjustment is required in patients with renal impairment. CASE REPORT In this report, we describe a 46-year-old female patient with recurrent MPM and severe renal impairment. Her treatment was managed with hyperthermic intraperitoneal cisplatin and doxorubicin along with intravenous ifosfamide following CRS. The cisplatin dose was reduced to 50% and the ifosfamide dose was reduced by 25%. The patient tolerated the procedure well, without deterioration in her renal function. At her 9-month follow-up, she did not report experiencing chemotherapy-related adverse effects, and her kidney function remained stable. CONCLUSIONS Severe renal impairment might not be a contraindication to using potentially nephrotoxic chemotherapeutic agents in CRS-BDIC.

Adamantinoma Metastasis to the Pelvis and Ovaries: A Case Report and Literature Review.

Adamantinoma, constituting a minute fraction of primary bone tumors, poses a diagnostic challenge due to its ambiguous histogenesis. This report outlines a distinctive case involving a 27-year-old female with a history of right tibial adamantinoma, presenting with bilateral pulmonary emboli and metastasis to the ovaries and pelvic lymph nodes. Following en bloc resection five years earlier, the patient underwent debulking surgery with hyperthermic intraperitoneal chemotherapy (HIPIC) and intraoperative radiotherapy (IORT) as a palliative measure. The procedure achieved substantial pelvic tumor reduction, and subsequent follow-ups indicated a favorable postoperative trajectory. This case underscores the rarity of adamantinoma metastasis to the ovaries and pelvis, being the first reported instance, shedding light on the challenges and potential benefits of a multimodal palliative approach. Further research is warranted to refine treatment strategies for metastatic adamantinoma and enhance patient outcomes.

The Use of Intraoperative Radiation Therapy (IORT) in Multimodality Management of Cancer Patients: a Single Institution Experience.

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.

A Rare Case of Guillain-Barré Syndrome Post-gastrojejunostomy and Literature Review.

Guillain-Barré syndrome (GBS) is a rare immune-mediated neuropathy causing destruction of the peripheral nervous system, with molecular mimicry playing a major role in its pathophysiology. Despite its rarity, it is considered the most common cause of acute flaccid neuromuscular paralysis in the United States. Although diagnosing GBS depends on the clinical presentation of the patient, cerebrospinal fluid sampling, nerve conduction studies, electromyography, magnetic resonance imaging, and ganglioside antibody screening can be used to confirm the diagnosis and rule out other differentials. Here, we report a rare case of GBS as a postoperative complication after a successful gastrojejunostomy to excise an adenocarcinoma in the second part of the duodenum. Such a complication is rare and not fully understood yet.

Rosai-Dorfman Disease: Case Series and Literature Review.

Rosai-Dorfman Disease (RDD), also known as sinus histiocytosis with massive lymphadenopathy, is an uncommon histiocytic condition characterized by massive histopathological aggregation of CD1-a negative, CD68-positive, and S100-positive histiocytes. It was initially described by Destombes in 1965 under the term "adenitis with lipid excess." However, it is named after Rosai and Dorfman who reported further histopathological features of the disease in 1969. The diagnosis of this non-Langerhans cell histiocytosis can be challenging and requires high clinical suspicion. The diagnostic process usually involves imaging, tissue biopsies, and genetic testing as needed. In this case series, we are presenting three cases of rare disease. Case 2 had both nodal and extranodal forms, which makes this case rarer than cases 1 and 3, which present with extranodal lesions.

A 51-Year-Old Woman with Advanced Peritoneal Mesothelioma and Stage 3b Chronic Kidney Disease Treated with Cytoreductive Surgery and Bidirectional Intraperitoneal Cisplatin and Ifosfamide Chemotherapy: A Case Report.

BACKGROUND Malignant mesotheliomas are rare, yet highly malignant tumors. Mesotheliomas are tumors that develop from mesothelial surfaces, with the pleura being the most common, followed by the peritoneum. The diagnosis of malignant peritoneal mesothelioma (MPM) is usually established when the disease is advanced, owing to the nonspecific clinical appearance and abdominal symptoms. Initially, MPM was treated with palliative systemic chemotherapy, with or without palliative surgery. However, cytoreductive surgery (CRS) combined with bidirectional intraoperative chemotherapy (BDIC) has recently emerged as a treatment option for MPM. BDIC creates a bidirectional chemotherapy gradient in the peritoneal tumor cells through the simultaneous use of intraperitoneal and intravenous chemotherapy. CRS, combined with BDIC (CRS-BDIC), allows the complete elimination of residual tiny tumor cells after complete removal of the visible tumor nodules. CASE REPORT Herein, we present a case of a 51-year-old woman with MPM and chronic kidney disease (CKD) stage 3b. Her treatment consisted of neoadjuvant chemotherapy and immunotherapy, followed by CRS-BDIC using intraperitoneal cisplatin and doxorubicin, and intravenous ifosfamide. The surgery was successful, with no immediate complications or decline in the patient's kidney function. On follow up 2 months later, the patient denies suffering any chemotherapy-related adverse effects, and her kidney profile remains stable. CONCLUSIONS In conclusion, nephrotoxicity, a known adverse effect of cisplatin and ifosfamide, might not be a contraindication for the use of these potentially nephrotoxic drugs in CRS-BDIC in patients with renal impairment.

Management of vascular complications after living donor liver transplantation.

BACKGROUND/AIMS: Vascular complications after liver transplantation remain a major source of morbidity and mortality for recipients especially those receiving LDLT owing to the complex vascular reconstruction. METHODOLOGY: During the period from May 1999 to May 2004, 518 LDLT were performed in the Department of Liver Transplantation and Immunology, Kyoto University Hospital, Japan. RESULTS: The recipients were 261 males and 257 females. Pediatric cases were 230. The indications were cholestatic diseases in 42.5%, chronic hepatocellular diseases (CHD) in 13.3%, HCC in 18.5%, other tumors in 2.7% and others in 23%. Small for- size grafts in 4.8%, accepted size grafts in 16.0%, optimum size grafts in 74.5% and large-for-size grafts in 4.6%. Vascular complications occurred during hospital stay in 6.4%, within 3 months from discharge in 2.5% and after 3 months from discharge in 6.0%. The success rate of the management of HAT was 83.3%, portal vein complications was 97.6% and hepatic vein complications was 84.6%. CONCLUSIONS: Careful preoperative evaluation and the proper intraoperative techniques in vascular reconstruction prevent vascular complications. Intraoperative microsurgical technique for hepatic artery reconstruction decreases hepatic artery complications. Routine post transplant Doppler examination should be performed at least twice a day for the first week after the operation. Immediate surgical intervention is required for acute vascular complications, whereas late complications may be treated by balloon angioplasty and endoluminal stent to avoid late complications and even mortality.

Feasibility of combining oncology surgery with bariatric surgery; a two-patient case series of sleeve gastrectomy with cytoreductive surgery and HIPEC.

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.

Surgical management of biliary complications following living donor liver transplantation.

BACKGROUND: Biliary complications (BC) account for much of the morbidities seen after living donor liver transplantation (LDLT). Surgical reconstruction might be necessary after the failure of endoscopic or percutaneous procedures. METHODS: Between November 2002 and December 2009, a total of 76 LDLTs were performed. Six patients were excluded from statistical analysis because of early graft or patient loss. RESULTS: Of 70, 26 (37.1%) developed BC; 12 (46.2%) were successfully managed by non-surgical procedures, three (11.5%) died from BC-related sepsis, one (3.8%) died from BC-unrelated causes, and 10 (38.5%) underwent surgical reconstruction. Of those 10, four patients had single duct reconstruction, five patients had double ducts reconstruction, and reconstruction was abandoned in one patient because of hepatic artery thrombosis. After a median follow-up period of 4.5 yr (0.1-6), seven (70%) remained well with no recurrent biliary problems, and three (30%) had recurrent BCs that were managed either conservatively or by retransplantation. Patients who underwent surgical reconstruction had significantly fewer hospital admissions, less need for invasive procedures, and shorter cumulative hospital stay (p < 0.05). CONCLUSIONS: In our experience, BCs after LDLT were frequently resistant to non-surgical procedures. Surgical reconstruction is associated with fewer hospital admissions and less need for invasive procedures leading to reduced resources utilization.
