BACKGROUND & AIMS Laparoscopic liver resection has gained wide acceptance and is established as a safe alternative to open liver resection. Until now, there is no prospective randomized comparative study between laparoscopic and open liver resection. Previous comparative studies reported minor resections for peripheral tumors, and enrolled small numbers of patients. Moreover, few reported the long term outcomes. The aim of this study is to compare perioperative and long term outcomes of laparoscopic versus open liver resection for hepatocellular carcinoma between two matched groups. METHODS 389 patients underwent liver resection for hepatocellular carcinoma during the period between 2004 and 2013. To overcome selection bias, we performed 1:1 match using propensity score matching between laparoscopic and open liver resection. RESULTS After propensity score matching, 88 patients were included in each group. Laparoscopic group had shorter hospital stay (8 vs. 10 days, p⩽0.001), and lower postoperative morbidity (12.5% vs. 20.4%, p=0.042). The 1-, 3- and 5-year overall survivals were 91.6%, 87.5%, and 76.4%, for laparoscopic group, and were 93.1%, 87.8%, and 73.2%, for open group (p=0.944). The 1-, 3- and 5-year disease free survivals were 69.7%, 52%, and 44.2%, for laparoscopic group, and 74.7%, 49.5%, 41.2%, for open group (p=0.944). CONCLUSIONS Our study showed comparative perioperative and long term outcomes between both groups, providing evidence regarding the safety and efficacy of laparoscopic liver resection for hepatocellular carcinoma.

BACKGROUND Obesity is a growing worldwide epidemic. There is association between obesity and pancreatic cancer risk. However, the impact of obesity on the outcome of pancreatoduodenectomy (PD) is controversial. The aim of this study was to elucidate effect of obesity on surgical outcomes of PD. STUDY DESIGN A case-control study. PATIENT AND METHODS We retrospectively studied all patients who underwent PD in our center between January 2000 and June 2012. Patients were divided into two groups; Group A (patients with BMI <25) and Group B (patients with BMI > 25). Preoperative demographic data, intraoperative data, and postoperative details were collected. RESULTS Only 112/471 patients (25.9%) had BMI > 25. The median intraoperative blood loss was more in overweight patients (P = 0.06). The median surgical time in group B was significantly longer than that in group A (P = 0.003). The overall incidence of complications was higher in the overweight group (P = 0.001). The severity of complications was also higher in the overweight group (P = 0.0001). Postoperative pancreatic fistula (POPF) (P = 0.0001) and hospital mortality (P = 0.001) were significantly higher in overweight patients. Oral intake was significantly delayed in overweight patients in comparison to normal weight group (P = 0.02). Postoperative stay was significantly longer in overweight patients (P = 0.0001). CONCLUSION PD is associated with an increased risk of postoperative morbidity in overweight patient. Overweight patients must not be precluded from undergoing PD. However, operative techniques and pharmacological prophylaxis to decrease POPF should be considered in overweight patients.

BACKGROUND Although the mortality and morbidity of pancreaticoduodenectomy (PD) have improved significantly over the past years, the concerns for elderly patients undergoing PD are still present. Furthermore, the frequency of PD is increasing because of the increasing proportion of elderly patients and the increasing incidence of periampullary tumors. This study aimed to analyze the outcomes of PD in elderly patients. METHODS We studied all patients who had undergone PD in our center between January 1995 and February 2015. The patients were divided into three groups based on age: group I (patients aged <60 years), group II (those aged 60 to 69 years) and group III (those aged ≥70 years). The primary outcome was the rate of total postoperative complications. Secondary endpoint included total operative time, hospital mortality, length of postoperative hospital stay, delayed gastric emptying, re-exploration, and survival rate. RESULTS A total of 828 patients who had undergone PD for resection of periampullary tumor were included in this study. There were 579 (69.9%) patients in group I, 201 (24.3%) in group II, and 48 (5.8%) in group III. The overall incidence of complications was higher in elderly patients (25.9% in group I, 36.8% in group II, and 37.5% in group III; P=0.006). There were more patients complicated with delayed gastric emptying in group II compared with the other two groups. There was no significant difference in the incidence of postoperative pancreatic fistula, biliary leakage, pancreatitis, pulmonary complications and hospital mortality. CONCLUSIONS PD can be performed safely in selected elderly patients. Advanced age alone should not be a contraindication for PD. The outcome of elderly patients who have undergone PD is similar to that of younger patients, and the increased rate of complications is due to the presence of associated comorbidities.

We report the first case series from Africa and the Middle East on choledochal cyst, a disease which shows significant geographical distribution with high incidence in the Asian population. In this study, the epidemiological data of the patients are presented and analyzed. Attention was paid to diagnostic imaging and its accuracy in the diagnosis and classification of choledochal cyst. Most cases of choledochal cyst disease have type I and IV-A cysts according to the Todani classification system, which support the etiological theories of choledochal cyst, especially Babbitts theory of the anomalous pancreaticobiliary duct junction, which are clearly stated. The difficulties and hazards of surgical management and methods used to avoid operative complications are clarified. Early and late postoperative complications are also included. This study should be followed by multicenter studies throughout Egypt to help assess the incidence of choledochal cysts in one of the largest populations in Africa and the Middle East.

INTRODUCTION Cases of primary neuroendocrine tumors in the liver combined with hepatocellular carcinoma are scarce. Such cases could present either as combined-type tumor or collision type. PRESENTATION OF CASE A 51-year-old man presented with a mass in the right hemiliver. Serum level of alpha-fetoprotein was slightly elevated (2.3 ng/ml), with normal CA19-9 and CA125. The patient underwent right hepatectomy. The resected specimen showed a well-defined and heterogeneous gray-white to brown friable tumor, 20 cm in diameter. Microscopically, the tumor consisted predominantly of monotonous small- to medium-sized neoplastic cells arranged in trabeculea separated by sinusoidal spaces. Immunohistochemically, the tumor cells were strongly positive for synaptophysin and focally positive for chromogranin-A. Interestingly, the tumor cells showed patchy positive coarse granular staining of HerPar-1 involving about 1% of the tumor cells. Glypican-3 staining was negative. These immunohistochemical findings supported the diagnosis of combined high grade neuroendocrine carcinoma and hepatocellular carcinoma. DISCUSSION Cases of primary neuroendocrine tumors in the liver combined 82 with hepatocellular carcinoma are scarce. The uniqueness of this case lies in the fact that the neuroendocrine carcinoma component comprised more than 99% of the tumor area, and the minor hepatocellular carcinoma component was detected only by the immunohistochemical staining for HepPar-1. CONCLUSION To the best of our knowledge, this is the first case of combined neuroendocrine carcinoma and hepatocellular carcinoma in Egypt.

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.

BACKGROUND The aim of this study was to evaluate the clinical and oncological outcomes after laparoscopic liver resection (LLR) in patients with hepatitis B and C virus-related hepatocellular carcinoma (HCC) with Child B or C cirrhosis. METHODS Between January 2004 and December 2013, LLR was performed in 232 patients with HCC. Of these, 141 patients also had pathologically proven cirrhosis. Sixteen patients with hepatitis B and C virus-related HCC with Child B or C cirrhosis were included in the study. Thirteen (81.3%) patients had Child B disease and three (18.8%) patients had Child C disease. RESULTS The median operation time was 215 min, the median estimated blood loss was 350 mL, and the median hospital stay was eight days. Three patients (18.8%) experienced complications after surgery. There was no postoperative mortality or reoperation. The mean follow-up period was 51.6 months. HCC recurred in eight (50%) patients: seven intrahepatic recurrences and one extrahepatic recurrence. The treatments for recurrence were laparoscopic reoperation in one (6.3%) patient, trans-catheter arterial chemo-embolization (TACE) in one (6.3%) patient, radiofrequency ablation (RFA) in one (6.3%) patient, and combined TACE and RFA in four (25%) patients. The five-year postoperative overall survival (OS) and disease-free survival (DFS) were 84.4% and 41.7%, respectively. CONCLUSIONS This study demonstrates that LLR can be safely used in patients with hepatitis B and C virus-related HCC and Child B or C cirrhosis, with acceptable survival outcomes.

BACKGROUND Surgical resection is the only hope for patients with cholangiocarcinoma (CC). This study is designed to assess the impact of cirrhosis on the outcome of surgical management for CC. PATIENT AND METHODS We retrospectively studied all patients who underwent surgical resection for hilar CC. Group I (patients with cirrhotic liver) and Group II (patients with non-cirrhotic liver). Preoperative demographic data, intra-operative data, and postoperative details were collected. RESULTS Only 102/243 patients (41.9%) had cirrhotic liver. Caudate lobe resection was more frequently performed in the non-cirrhotic group (P = <0.001). There was no difference between both groups regarding intraoperative blood loss and the need for blood transfusion. The median postoperative stay was higher in the cirrhotic group (P = 0.063). The incidence of early postoperative liver cell failure was significantly higher in the cirrhotic group (P = <0.001). Cirrhosis was associated with significantly lower overall survival (P = <0.001). CONCLUSION Patients with concomitant liver cirrhosis and hilar CC should not be precluded from surgical resection and should be considered for resection at high volume centers with expertise available to manage liver cirrhosis. The incidence of early postoperative liver cell failure was significantly higher in the cirrhotic group.

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%.
