Predictive Factors of De Novo Malignancies After Living-Donor Liver Transplantation: A Single-Center Experience.

BACKGROUND: De novo malignancies are a major reason of long-term mortalities after liver transplantation. However, they usually receive minimal attention from most health care specialists. The current study aims to evaluate our experience of de novo malignancies after living-donor liver transplantation (LDLT). METHODS: We reviewed the data of patients who underwent LDLT at our center during the period between May 2004 and December 2018. RESULTS: During the study period, 640 patients underwent LDLT. After a mean follow-up period of 41.2 ± 25.8 months, 15 patients (2.3%) with de novo malignancies were diagnosed. The most common de novo malignancies were cutaneous cancers (40%), post-transplantation lymphoproliferative disorders (13.3%), colon cancers (13.3%), and breast cancers (13.3%). Acute cellular rejection (ACR) episodes occurred in 10 patients (66.7%). Mild ACR occurred in 8 patients (53.3%), and moderate ACR occurred in 2 patients (13.3%). All patients were managed with aggressive cancer treatment. The mean survival after therapy was 40.8 ± 26.4 months. The mean overall survival after LDLT was 83.9 ± 52.9 months. Twelve patients (80%) were still alive, and 3 mortalities (20%) occurred. The 1-, 5-, and 10-year overall survival rates after LDLT were 91.7%, 91.7%, and 61.1%, respectively. On multivariate regression analysis, smoking history, operation time, and development of ACR episodes were significant predictors of de novo malignancy development. CONCLUSIONS: Liver transplant recipients are at high risk for the development of de novo malignancies. Early detection and aggressive management strategies are essential to improving the recipients' survival.

Laparoscopic Pancreaticodudenectomy for Periampullary Tumor: Should it be a Routine? A Propensity Score-matched Study.

INTRODUCTION: Laparoscopic pancreaticoduodenectomy (LPD) is a complex and challenging procedure even with experienced surgeons. The aim of this study is to evaluate the feasibility and surgical and oncological outcomes of LPD compared with open pancreaticoduodenectomy (OPD). PATIENTS AND METHOD: This is a propensity score-matched analysis for patients with periampullary tumors who underwent PD. Patients underwent LPD and matched group underwent OPD included in the study. The primary outcome measure was the rate of total postoperative morbidities. Secondary outcomes included operative times, hospital stay, wound length and cosmosis, oncological outcomes, recurrence rate, and survival rate. RESULTS: A total of 111 patients were included in the study (37 LPD and 74 OPD). The conversion rate from LPD to OPD was 4 cases (10.8%). LPD provides significantly shorter hospital stay (7 vs. 10 d; P=0.004), less blood loss (250 vs. 450 mL, P=0.001), less postoperative pain, early oral intake, and better cosmosis. The length of the wound is significantly shorter in LPD. The operative time needed for dissection and reconstruction was significantly longer in LPD group (420 vs. 300 min; P=0.0001). Both groups were comparable as regards lymph node retrieved (15 vs. 14; P=0.21) and R0 rate (86.5% vs. 83.8%; P=0.6). No significant difference was seen as regards postoperative morbidities, re-exploration, readmission, recurrence, and survival rate. CONCLUSIONS: LPD is a feasible procedure; it provided a shorter hospital stay, less blood loss, earlier oral intake, and better cosmosis than OPD. It had the same postoperative complications and oncological outcomes as OPD.

Clamp-Crush Technique Versus Harmonic Scalpel for Hepatic Parenchymal Transection in Living Donor Hepatectomy: a Randomized Controlled Trial.

BACKGROUND: Hepatic parenchymal transection is the most invasive step in donor operation. During this step, blood loss and unintended injuries to the intrahepatic structures and hepatic remnant may occur. There is no evidence to prove the ideal techniques for hepatic parenchymal transection. The aim of this study is to compare the safety, efficacy, and outcome of clamp-crush technique versus harmonic scalpel as a method of parenchymal transection in living-donor hepatectomy. METHODS: Consecutive living liver donors, undergoing right hemi-hepatectomy, during the period between May 2015 and April 2016, were included in this prospective randomized study. Cases were randomized into two groups; group (A) harmonic scalpel group and group (B) Clamp-crush group. RESULTS: During the study period, 72 cases underwent right hemi-hepatectomy for adult living donor liver transplantation and were randomized into two groups. There were no statistically significant differences between the two groups regarding preoperative demographic and radiological data. Longer operation time and hepatectomy duration were found in group B. There were no significant differences between the two groups regarding blood loss, blood loss during hepatectomy, and blood transfusion. More unexpected bleeding events occurred in group A. Higher necrosis at the cut margin of the liver parenchyma was noted in group A. There were no statistically significant differences between the two groups regarding postoperative ICU stay, hospital stay, postoperative morbidities, and readmission rates. CONCLUSION: Clamp-crush technique is advocated as a simple, easy, safe, and cheaper method for hepatic parenchymal transection in living donors.

Adrenalectomy for solitary recurrent hepatocellular carcinoma five years after living donor liver transplantation: A case report.

INTRODUCTION: The adrenal gland is a rare site for hepatocellular carcinoma (HCC) recurrence after living-donor liver transplantation (LDLT). Solitary adrenal recurrence can be managed by surgical excision, with expected better survival outcomes. We describe a rare case of successful left adrenalectomy of solitary recurrent HCC in the left adrenal gland 5 years after LDLT. PRESENTATION: 59 years male patient with HCC complicating chronic HCV infection received a right hemi-liver graft from his son. The actual graft weight was 1208 g and GRWR was 1.5. The patient started oral direct acting antiviral drugs for recurrent HCV 2 years after LDLT. A left adrenal mass was detected on follow up radiology. No other metastatic lesions were detected on metastatic workup. Left adrenalectomy was done by an anterior approach. The postoperative course was uneventful and was discharged a week after operation. Postoperative pathological and immune-histochemical examinations confirmed the metastatic HCC nature of the mass. The patient is under regular follow up with no recurrences 6 month after resection. DISCUSSION: There is no consensus regarding the management of HCC recurrence after LDLT. Most patients had multi-organ recurrences and usually offered palliative or supportive care. Solitary HCC recurrence offers a better chance for more aggressive therapy, offering better prognosis. CONCLUSION: Solitary adrenal recurrence of HCC after LDLT is extremely rare. Strict follow up protocol is necessary to allow early detection of tumor recurrence. Curative surgical resection is a safe option associated with low morbidity and expected to have a good long-term survival.

Outcomes of Living Donor Liver Transplantation for Patients with Preoperative Portal Vein Problems.

BACKGROUND: Portal vein thrombosis (PVT) is a common complication for patients with end-stage liver disease. The presence of PVT used to be a contraindication to living donor liver transplantation (LDLT). The aim of this study is to evaluate the influence of preoperative PVT on perioperative and long-term outcomes of the recipients after LDLT. METHODS: We reviewed the data of patients who underwent LDLT during the period between 2004 till 2017. RESULTS: During the study period, 500 cases underwent LDLT. Patients were divided into three groups. Group I included non-PVT, 446 patients (89.2%); group II included attenuated PV, 26 patients (5.2%); and group III included PVT, 28 patients (5.6%). Higher incidence of hematemesis and encephalopathy was detected in PVT (p = 0.001). Longer anhepatic phase was found in PVT (p = 0.013). There were no significant differences between regarding operation time, blood loss, transfusion requirements, ICU, and hospital stay. The 1-, 3-, and 5-year overall survival (OS) rates of non-PVT were 80.5%, 77.7%, and 75%, and for attenuated PV were 84.6%, 79.6%, and 73.5%, and for PVT were 88.3%, 64.4%, and 64.4%, respectively. There was no significant difference between the groups regarding OS rates (logrank 0.793). CONCLUSION: Preoperative PVT increases the complexity of LDLT operation, but it does not reduce the OS rates of such patients.

Trends and outcomes of pancreaticoduodenectomy for periampullary tumors: A 25-year single-center study of 1000 consecutive cases.

AIM: To evaluate the evolution, trends in surgical approaches and reconstruction techniques, and important lessons learned from performing 1000 consecutive pancreaticoduodenectomies (PDs) for periampullary tumors. METHODS: This is a retrospective review of the data of all patients who underwent PD for periampullary tumor during the period from January 1993 to April 2017. The data were categorized into three periods, including early period (1993-2002), middle period (2003-2012), and late period (2013-2017). RESULTS: The frequency showed PD was increasingly performed after the year 2000. With time, elderly, cirrhotic and obese patients, as well as patients with uncinate process carcinoma and borderline tumor were increasingly selected for PD. The median operative time and postoperative hospital stay decreased significantly over the periods. Hospital mortality declined significantly, from 6.6% to 3.1%. Postoperative complications significantly decreased, from 40% to 27.9%. There was significant decrease in postoperative pancreatic fistula in the second 10 years, from 15% to 12.7%. There was a significant improvement in median survival and overall survival among the periods. CONCLUSION: Surgical results of PD significantly improved, with mortality rate nearly reaching 3%. Pancreatic reconstruction following PD is still debatable. The survival rate was also improved but the rate of recurrence is still high, at 36.9%.

Ligation of huge spontaneous porto-systemic collaterals to avoid portal inflow steal in adult living donor liver transplantation: A case-report.

INTRODUCTION: In adult living donor liver transplantation (LDLT), maintenance of adequate portal inflow is essential for the graft regeneration. Portal inflow steal (PFS) may occur due to presence of huge spontaneous porto-systemic collaterals. A surgical procedure to increase the portal inflow is rarely necessary in adult LDLT. PRESENTATION: A 52 years male patient with end-stage liver disease due to chronic hepatitis C virus infection. Preoperative portography showed marked attenuated portal vein and its two main branches, patent tortuous splenic vein, multiple splenic hilar collaterals, and large lieno-renal collateral. He received a right hemi-liver graft from his nephew. Exploration revealed markedly cirrhotic liver, moderate splenomegaly with multiple collaterals and large lieno-renal collateral. Upon dissection of the hepato-duodenal ligament, a well-developed portal vein could be identified with a small mural thrombus. The recipient portal vein stump was anastomosed, in end to end fashion, to the graft portal vein. Doppler US showed reduced portal vein flow, so ligation of the huge lieno-renal collateral that allows steal of the portal inflow. After ligation of the lieno-renal collateral, improvement of the portal vein flow was observed in Doppler US. DISCUSSION: There is no accepted algorithm for managing spontaneous lieno-renal shunts before, during, or after liver transplantation, and evidence for efficacy of treatments remains limited. We report a case of surgical interruption of spontaneous huge porto-systemic collateral to prevent PFS during adult LDLT. CONCLUSION: Complete interruption of large collateral vessels might be needed as a part of adult LDLT procedure to avoid devastating postoperative PFS.

Impact of donor-recipient genetic relationship on outcome of living donor liver transplantation.

Living donor liver transplantation (LDLT) is a valuable option for expanding the donor pool, especially in localities where deceased organ harvesting is not allowed. In addition, rejection rates were found to be lower in LDLT, which is attributed to the fact that LDLT is usually performed between relatives. However, the impact of genetic relation on the outcome of LDLT has not been studied. In this study, we examined the difference in rejection rates between LDLT from genetically related (GR) donors and genetically unrelated (GUR) donors. All cases that underwent LDLT during the period from May 2004 until May 2014 were included in the study. The study group was divided into 2 groups: LDLT from GR donors and LDLT from GUR donors. A total of 308 patients were included in the study: 212 from GR donors and 96 from GUR donors. Human leukocyte antigen (HLA) typing was not included in the workup for matching donors and recipients. GUR donors were wives (36; 11.7%), sons-in-law (7; 2.3%), brothers-in-law (12; 3.9%), sisters-in-law (1; 0.3%), and unrelated (38; 12.3%). The incidence of acute rejection in the GR group was 17.4% and 26.3% in the GUR group (P value = 0.07). However, there was a significant difference in the incidence of chronic rejection (CR) between the 2 groups: 7% in GR group and 14.7% in the GUR group (P value = 0.03). In terms of overall survival, there was no significant difference between both groups. LDLT from the GUR donors is not associated with a higher incidence of acute cellular rejection. However, CR was significantly lower when grafts were procured from GR donors. HLA matching may be recommended before LDLT from GUR donors. Liver Transplantation 23:43-49 2017 AASLD.

Spray Diathermy Versus Harmonic Scalpel Technique for Hepatic Parenchymal Transection of Living Donor.

BACKGROUND: Liver parenchymal transection is the most invasive and challenging part in the living donor operation. The study was planned to compare the safety, efficacy, and outcome of harmonic scalpel versus spray diathermy as a method of parenchymal liver transection in donor hepatectomy. PATIENT AND METHOD: Eighty consecutive patients, who were treated by living donor liver transplantation (LDLT), were included in the study. The study population was divided into two groups according to the method of liver transection: group A by harmonic scalpel (HS) and group B by spray diathermy (SD). The primary outcome was the volume of blood loss during transection. Secondary outcomes were time of transection, number of ligatures needed during transection, pathological changes at cut surface, postoperative morbidities, cost, and hospital stay RESULTS: Blood loss during overall liver transection and in each zone was significantly less in the SD than in the HS group (P = 0.015). The number of ligatures was significantly less in the SD than in the HS group (P = 0.0001). The SD group had significantly higher level of serum bilirubin, serum glutamic pyruvic transaminase (SGPT), and international normalized ratio (INR) levels on postoperative day 3 than the HS group. Lateral tissue coagulation and hepatic necrosis are significantly less in HS group. The overall incidence of postoperative morbidities was the same in both groups. The cost was higher in HS group than SD group (US$760 vs. US$40 P = 0.0001). CONCLUSION: Spray diathermy is an effective method of parenchymal transection with significantly lower blood loss and lower cost compared to HS with no increase in morbidity. HS is associated with earlier recovery of liver functions.

Hepatic venous outflow obstruction after living donor liver transplantation managed with ectopic placement of a foley catheter: A case report.

INTRODUCTION: The early hepatic venous outflow obstruction (HVOO) is a rare but serious complication after liver transplantation, which may result in graft loss. We report a case of early HVOO after living donor liver transplantation, which was managed by ectopic placement of foley catheter. PRESENTATION: A 51 years old male patient with end stage liver disease received a right hemi-liver graft. On the first postoperative day the patient developed impairment of the liver functions. Doppler ultrasound (US) showed absence of blood flow in the right hepatic vein without thrombosis. The decision was to re-explore the patient, which showed torsion of the graft upward and to the right side causing HVOO. This was managed by ectopic placement of a foley catheter between the graft and the diaphragm and the chest wall. Gradual deflation of the catheter was gradually done guided by Doppler US and the patient was discharged without complications. DISCUSSION: Mechanical HVOO results from kinking or twisting of the venous anastomosis due to anatomical mismatch between the graft and the recipient abdomen. It should be managed surgically by repositioning of the graft or redo of venous anastomosis. Several ideas had been suggested for repositioning and fixation of the graft by the use of Sengstaken-Blakemore tubes, tissue expanders, and surgical glove expander. CONCLUSION: We report the use of foley catheter to temporary fix the graft and correct the HVOO. It is a simple and safe way, and could be easily monitored and removed under Doppler US without any complications.

Problem of living liver donation in the absence of deceased liver transplantation program: Mansoura experience.

We report our experience with potential donors for living donor liver transplantation (LDLT), which is the first report from an area where there is no legalized deceased donation program. This is a single center retrospective analysis of potential living donors (n = 1004) between May 2004 and December 2012. This report focuses on the analysis of causes, duration, cost, and various implications of donor exclusion (n = 792). Most of the transplant candidates (82.3%) had an experience with more than one excluded donor (median = 3). Some recipients travelled abroad for a deceased donor transplant (n = 12) and some died before finding a suitable donor (n = 14). The evaluation of an excluded donor is a time-consuming process (median = 3 d, range 1 d to 47 d). It is also a costly process with a median cost of approximately 70 USD (range 35 USD to 885 USD). From these results, living donor exclusion has negative implications on the patients and transplant program with ethical dilemmas and an economic impact. Many strategies are adopted by other centers to expand the donor pool; however, they are not all applicable in our locality. We conclude that an active legalized deceased donor transplantation program is necessary to overcome the shortage of available liver grafts in Egypt.

Biliary complications in living donor right hepatectomy are affected by the method of bile duct division.

The bile duct division is a crucial step in the donor hepatectomy. Multiple small ducts will make the biliary reconstruction more difficult and may influence the outcome of the recipient. Biliary leakage, bilomas and biliary strictures are well recognized donor complications that may be directly linked to bile duct division. Biliary division still needs more standardization. This work aims to analyze our experience with two different methods of bile duct division in relation to the development of intraoperative and postoperative biliary complications. Between April 2004 and March 2013, 216 liver donors underwent right hepatectomy, in Gastro-Enterology Surgical Center, Mansoura University, Egypt. According to the method of bile duct division, the study population was divided into 2 groups; 1- extrahepatic dissection group (EDG) and 2- fluoroscopy guided transection group (FGG), each comprised 108 patients. Data were collected from a prospectively registered database, with special emphasis on the occurrence of biliary complications. Complications were classified according to the latest version of Clavien classification. Intraoperative biliary complications did not differ between both groups, p = 0.313. The commonest postoperative complication was biliary leak/biloma accounting for 32.5% of all donor complications, followed by non-biliary fluid collections. 24 (11.1%) donors developed 27 biliary complications. The FGG showed significantly less biliary complications (5.6%, 6 donors), when compared to EDG (15.7%, 18 donors), p = 0.015. Grade 3 complications were significantly higher in EDG, p = 0.024. On multivariate analysis, the only significant factor predicting the occurrence of biliary complications was the use of fluoroscopy guided bile duct division, p = 0.009. In conclusion, we believe that the proposed method of biliary division is safe, simple and reproducible.

Factors affecting recurrence and survival after living donor liver transplantation for hepatocellular carcinoma.

BACKGROUND/AIMS: HCC is a leading cause of cancer-related deaths worldwide. The main etiological factor in Egypt is HCV infection. Lack of cadaveric transplantation in Egypt makes LDLT the only available option for liver transplantation for HCC patients with advanced cirrhosis and/or non-resectable tumors. METHODOLOGY: Between January 2004 and April 2012, 170 patients underwent LDLT at the Liver Transplantation Unit, Mansoura University, and 52 (30.6%) were shown to have HCC by pathological examination. Patient demographics, preoperative interventions and pathological findings were evaluated for their influence on recurrence and survival. Patients were followed-up with abdominal sonography and AFP every 3 months and CT scans every 6 months. Median follow-up was 22.9 months. RESULTS: The main cause of underlying cirrhosis was HCV (96.2%). One or more different pre-transplant treatments of HCC were performed in 14 (27.4%) patients. The median total size was 4cm (0.8-15.5). Microvascular invasion was detected in 16 (31.4%) patients; 16 patients proved to have tumors beyond the Milan criteria. Pre-transplantation AFP more than 200ng/mL, total tumor size more than 8cm and microvascular invasion influenced recurrence rate on univariate analysis. Multivariate analysis identified AFP (p = 0.016) as independent factor for recurrence. Survival was significantly affected by AFP (p = 0.003) and microvascular invasion (p = 0.003). CONCLUSIONS: LDLT is a feasible option for patients with HCC on top of cirrhosis with good survival and recurrence-free survival rates.

Outcome of right hepatectomy for living liver donors: a single Egyptian center experience.

BACKGROUND: This study aims to evaluate living liver donor outcome after right hepatectomy in a single Egyptian center. PATIENTS AND METHODS: Between April 2004 and July 2010, 100 living donors underwent right hepatectomy. Their medical records and postoperative follow-up visits were retrospectively revised. Perioperative complications were reported. Postoperative complications were classified according to the five tier version of Clavien system. RESULTS: There were 71 males and 29 females. The mean age was 27.6 ± 7.4 years. The mean graft weight was 999 ± 167 g and the mean volume percent of the remaining liver was 36.8 ± 8%. The mean ICU and hospital stay were 2.6 ± 2.7 and 12.4 ± 9.1, respectively. A total of 57 complications developed in 38 donors (38%). The commonest complication type was biliary complications. There were 22 grade I, 6 grade II, 15 grade IIIa, 12 grade IIIb, 1 grade IVa, and 1 grade V complications. One donor died due to posttransfusion ARDS on the 30th postoperative day. On follow-up, no donor developed long lasting disability. A donor died in a road traffic accident 1 year after donation. DISCUSSION AND CONCLUSIONS: Donor right hepatectomy is not an entirely safe procedure. Biliary complications are the commonest early postoperative complications.

Caudate lobe resection with major hepatectomy for central cholangiocarcinoma: is it of value?

BACKGROUND/AIMS: The aim of this study was to evaluate the importance of concomitant caudate lobe resection in the course of major hepatectomy for hilar cholangiocarcinoma. METHODOLOGY: During the period between January 1995 and December 2010, 159 patients were subjected to major hepatectomy with or without total caudate lobe resection at the Gastroenterology Centre, Mansoura University. These patients were divided in two groups: 1) a caudate lobe preservation (CLP) group (79 patients) and 2) a caudate lobe resection (CLR) group (80 patients). All patient data were retrospectively reviewed. RESULTS: This study included 94 men and 65 women with a mean age of 53.5±0 years without operative mortality. No differences were observed between groups regarding operative time, blood loss or the development of any individual postoperative complication. There were 23 (28.8%) margin-positive resections in the CLR group and 49 (62%) margin-positive resections in the CLP group (p≤0.001). Recurrence was confirmed in 53 (67.1%) and in 41(51.3%) patients in the CLP and CLR groups, respectively (p=0.031). The median survival of the CLR group was 36 months with a 5-year survival rate of 28%, while the median survival of the CLP group was 22 months with a 5-year survival rate of 5% (p≤0.001). CONCLUSIONS: Caudate lobe resection in combination with major hepatectomy did not affect operative or postoperative morbidity and mortality. However, it led to higher rates of margin-negative resections and significantly improved survival.

Caudate lobe resection for hepatocellular carcinoma.

BACKGROUND/AIMS: Hepatocellular carcinoma (HCC) originating in the caudate lobe is rare, and the treatment for this type of carcinoma is a complex surgical procedure. We aimed to evaluate the surgical outcomes after isolated caudate lobe resection for HCC. METHODOLOGY: We retrospectively analyzed 30 consecutive patients with HCC originating in the caudate lobe who underwent isolated caudate lobe resection. RESULTS: Thirty patients underwent caudate lobe resection for HCC. The main sites of the tumors were located in the Spiegel lobe, the paracaval portion and caudate process. The surgical margin was tumor negative in all of the patients. The median tumor size was 4.3cm. The mean operative time was 230 ± 50min and the intraoperative blood loss was 1200 ± 200mL. The hospital morbidity rate was 33%. There was no postoperative mortality. The mean survival rate was 25.3+11.7 months. The overall survival rates were 62%, 34% and 11% at 1, 3 and 5 years, respectively. The disease free survival rate after isolated caudate lobectomy was 31% at 3 years. Recurrence was noted in 12 patients (40%). Eleven patients were identified as having intrahepatic recurrences and 1 patient as having peritoneal dissemination. CONCLUSIONS: Isolated caudate lobe resection is a feasible procedure and can be undertaken with low morbidity and nil mortality. Careful technique and detailed anatomic knowledge of the caudate lobe are essential for this procedure.

Post-cholecystectomy biliary injuries: one center experience.

BACKGROUND/AIMS: Post-cholecystectomy bile duct injuries (BDIs) represent a challenge in diagnosis and management. METHODOLOGY: From March 1995 to August 2009, 274 patients with post-cholecystectomy BDIs were managed at our center. All patients were subjected to laboratory tests, sonography, ERCP and MRCP. The management varied according to the type of injury. RESULTS: Seventy-one (25.9%) LC and 203 (74.1%) OC were performed; 8(2.9%) were detected intraoperatively; 270 patients were referred from other hospitals. From those discovered intraoperatively, 7 had hepatico-jejunostomy and one died from severe peritonitis; 11 (4%) presented with generalized and 112 (40.9%) with localized peritonitis. The leak site was the cystic duct (57 cases), accessory duct in the liver bed (5 cases), right hepatic duct (4 cases) and lateral tear in the CBD (12 cases). Endoscopic stenting was performed for all of them. The remaining 34 patients had a completely ligated distal duct and therefore had hepatico-jejunostomy Roux loop; 143 patients (52.2%) presented with early (79 cases) and late (64 cases) jaundice; 126 cases had hepatico-jejunostomy. The remaining 17 patients were treated by balloon dilatation. CONCLUSIONS: Endoscopic stenting can manage cases with cystic or accessory duct leak while, hepatico-jejunostomy Roux loop represents the golden procedure for management of transected or ligated CBD.

Outcome of pouch surgery for ulcerative colitis: single center experience.

AIM: The purpose of the present study is to present the experience and evaluate the outcome of pouch surgery for patients with ulcerative colitis (UC). METHODOLOGY: Fifty eight patients underwent surgery for UC between 1996 and 2007 at Mansoura Gastroenterology Center. A retrospective analysis has been done of all patients with UC undergoing surgery which includes details of the patient's history, indication of surgery, type of operation, postoperative morbidity, and functional outcome. RESULTS: The main indication for operation was failed medical treatment (n=42, 72.4%). Pouch surgery was performed in 25/58 patients (43.1%). The majority of patients, 23/25 (92%) had J-shaped pouch and most patients, 19 (76%), underwent a stapled anastomosis. Twenty patients (80%) had a defunctioning ileostomy. There was one postoperative death after pouch surgery. Early complications after pouch surgery included pelvic sepsis (n=4), small bowel obstruction (n=2), pouch hemorrhage (n=1), wound sepsis (n=3). Long-term follow-up data were available for 14 patients. The most common long-term complication was anastomotic stricture (n=9, 42.6%). Five patients (35.7%) presented with pouchitis. Median daytime stool frequency was 5.1. Three patients (21.4%) presented with fecal incontinence. CONCLUSION: Pouch surgery is a major one that attains many complications. However, the long term results and patient's satisfaction are reasonable.

Lifestyle, occupational, and reproductive factors in relation to pancreatic cancer risk.

OBJECTIVES: This study examined the epidemiology of pancreatic cancer in Egypt. METHODS: We obtained detailed information on smoking, occupational, medical, and reproductive histories from 194 pancreatic cancer cases and 194 controls. RESULTS: Compared with not smoking, smoking cigarettes alone or in conjunction with other smoking methods (eg, water pipe, cigar) was associated with an increased risk (odds ratio [OR], 4.5 and 7.8; 95% confidence interval [95% CI], 1.9-10.7 and 3.0-20.6, respectively). Passive smoking was also a significant risk factor (OR, 6.0; 95% CI, 2.4-14.8). The risk of pancreatic cancer was elevated among subjects exposed to pesticides (OR, 2.6; 95% CI, 0.97-7.2). A prior diagnosis of diabetes mellitus for a period of 10 years was associated with higher risk (OR, 5.4; 95% CI, 1.5-19.9). For women, having 7 or more live births and lactating for 144 months or longer were associated with a reduced risk (OR, 0.5 and 0.2; 95% CI, 0.2-1.3 and 0.1-0.9, respectively). No association was found between family history, allergy, or obesity and pancreatic cancer in Egypt. CONCLUSIONS: Multiple tobacco consumption methods, passive smoking, pesticide exposures, and diabetes are associated with an increased risk for pancreatic cancer. Prolonged lactation and increased parity are associated with a reduced risk for pancreatic cancer.
