Developmental abnormalities of liver including ectopic liver tissue (ELT) are rare conditions. Few cases presenting ELT have been reported in literature till now. Even though the most common area seen is gallbladder, it is detected both abdominal and thoracic sites. There is a relationship between HCC and ectopic liver that necessitates the removal. A 51-year-old female was hospitalized because of abdominal pain. Gallstone and bile duct dilatation were determined during ultrasonographic (USG) evaluation. The patient was operated for cholecystectomy following a successful endoscopic retrograde cholangiopancreatography (ERCP). During operation, a mass located on gallbladder with its unique vascular support was identified and resected together with gallbladder. The mass had a separate vascular stalk arising from liver parenchyma substance and it was clipped with laparoscopic staples. The histopathological examination revealed that the mass adherent to gallbladder was ectopic liver confirming the intraoperative observation. The postoperative course of patient was uneventfull and she was discharged at the second day after the operation. Ectopic liver tissue is incidentally found both in abdominal and thoracic cavity. ELT can rarely be diagnosed before surgical procedures or autopsies. It can be overlooked easily by radiological techniques. Although it does not usually produce any symptom clinically, it can rarely result in serious complications such as bleeding, pyloric and portal vein obstruction. ELT also has the capacity of malignant transformation to hepatocellular carcinoma that makes it essential to be removed. Although ELT is rarely seen, it should be removed when recognized in order to prevent the complications and malignant transformation.

The aim of this study was to evaluate the potential effect of intraperitoneal administration of leptin on the hepatic regeneration and the mitotic index. 56 Sprague-Dawley rats were divided into 7 groups each containing 8 rats. Group 1 was evaluated as the sham group and no surgical procedure was performed on animals. The rats in groups 2, 3, and 4 (named C24, C48, C72, respectively) were given intraperitoneal injection of 2 ml/kg normal saline 60 minutes before the surgical procedure consisting of laparotomy and 70% hepatectomy. These groups were used as controls at 24, 48, and 72 hours. The rats in groups 5, 6, and 7 (named L24, L48, and L72, respectively) were given intraperitoneal injection of 20 µg/kg doses of recombinant mouse leptin 60 minutes before the same surgical procedure. These groups were evaluated as the experiment groups at 24, 48, and 72 hours. Blood samples were collected for aspartate aminotransferase (AST) and alanine aminotransferase (ALT) and the remaining tissue samples were obtained for liver histopathology, regeneration rate, and mitotic index (MI). The weights of the remaining livers were also noted. The values of AST and ALT were higher in the groups that were administered leptin and they had significantly higher mitotic index than the other groups. Leptin also significantly increased the regeneration ratio as compared to the control group. The weights of the remaining livers were also higher in the leptin groups. Intraperitoneal administration of leptin was observed to increase liver regeneration and mitotic rate in 70% hepatectomized rats.

To report the results of open surgery for patients with basket impaction during endoscopic retrograde cholangiopancreatography (ERCP) procedure. Basket impaction of either classical Dormia basket or mechanical lithotripter basket with an entrapped stone occurred in six patients. These patients were immediately operated for removal of stone(s) and impacted basket. The postoperative course, length of hospital stay, diameter of the stone, complication and the surgical procedure of the patients were reported retrospectively. Six patients (M/F, 0/6) were operated due to impacted basket during ERCP procedure. The mean age of the patients was 64.33 ± 14.41 years. In all cases the surgery was performed immediately after the failed ERCP procedure by making a right subcostal incision. The baskets containing the stone were removed through longitudinal choledochotomy with the stone. The choledochotomy incisions were closed by primary closure in four patients and T tube placement in two patients. All patients were also performed cholecystectomy additionally since they had cholelithiasis. In patients with T-tube placement it was removed on the 13(th) day after a normal T-tube cholangiogram. The patients remained stable at postoperative period and discharged without any complication at median 7 d. Open surgical procedures can be applied in patients with basket impaction during ERCP procedure in selected cases.

Introduction: Endoscopic retrograde cholangiopancreatography is extremely painful and uncomfortable when performed without anesthesia. However, the type of anesthesia to be applied remains a matter of debate. In this study, general anesthesia and sedation procedures were compared in endoscopic retrograde cholangiopancreatography performed by the same anesthesia and surgical team over a 5-year period. Materials and Method: Patients aged over 65 years were divided into two groups, general anesthesia and sedation, and their data were analyzed retrospectively. Anesthesia complications, surgical complications, duration of the procedure, need for intensive care, and length of hospital stay and intensive care needs were compared between groups in 2812 patients. Results: Data from 1885 patients were analyzed. The procedure time and hospital stay were shorter, and anesthesia-related complication rate was lower in the general anesthesia group. Although not statistically significant, mortality was higher, and the need for intensive care was similar to the sedation group. The complication rate significantly increased in patients aged over 75 years Conclusion: Endoscopic retrograde cholangiopancreatography can be performed under deep sedation or general anesthesia. The experience of the anesthetist is an important factor for this choice. The use of sedation in geriatric patients is associated with more complications that require airway interventions. In addition, anesthesia complications due to prolonged procedures were more common in the sedation group. Conclusion: In our study, it was observed that general anesthesia was safer for endoscopic retrograde cholangiopancreatography procedures performed in geriatric patients by an experienced anesthesia and surgical team.

Background: Laparoscopic cholecystectomy, particularly in the same hospital stay, has been widely recommended to treat gallstone-pancreatitis over the last decade. Although pancreatitis produces severe oxidative injury, laparoscopy exerts an additional effect over that is produced by pancreatitis. The preconditioning phenomenon previously reported as protective in open surgery is a beneficial maneuver also in laparoscopic surgery. So in the present study we have tried to find out the effect of laparoscopic preconditioning over the pancreatitis in cerulein-induced pancreatitis rats. Methods: Acute pancreatitis was induced in 24 rats weighing between 280 and 350 g by three subcutaneous injection of 80 μg/kg of body weight cerulein. A 1-cm midline laparotomy was performed for all rats, and then they were randomly assigned to one of the following three groups (n=8 for each): Group I (control), Group II (laparoscopy), and Group III (laparoscopic preconditioning [L-Pre]). After that, a catheter was placed into the peritoneum for the creation of the pneumoperitoneum (Pp) in all the animals except the control group. The rats of Groups II and III were subjected to 60 minutes of Pp with 15 mm Hg intraabdominal pressure followed by 30 minutes of deflation. The L-Pre procedure was applied to Group III immediately before the laparoscopic procedure. Blood samples were taken for biochemical assays. Pancreas tissue samples were taken for light microscope analysis. Results: The light microscopy of the pancreas tissues revealed that cerulein injection caused edema and sparse inflammatory cell infiltration mimicking the edematous pancreatitis. However, the application of laparoscopy over the pancreatitis produced significant inflammatory cell infiltration, acinus vacuolization, and necrosis (in one case) in addition to edema. But, the laparoscopic preconditioning maneuver applied before the laparoscopy significantly decreased in particular acinary vacuolization and cell infiltration. Therefore the total sum of the histopathological score of the L-Pre group was significantly less than that of the laparoscopy group. The biochemical analysis of the groups revealed that laparoscopy caused significant elevation of malondialdehyde levels and decrease of reduced glutathione values. However, the addition of preceding preconditioning produced significant amelioration of these parameters. Conclusion: Laparoscopic preconditioning may be a useful method to decrease the oxidative injury in cases undergoing cholecystectomy for biliary pancreatitis. But, it should be emphasized that this was a restricted experimental study, and further clinical studies are needed to adopt these results into clinical settings.

Background/Aim: In Endoscopic retrograde cholangiopancreatography (ERCP), Ampulla of Vater is found on the posteromedial wall of the second part of the duodenum. However, ectopic expansion of the common bile duct to the 3rd or 4th part of the duodenum or the proximal stomach, pylorus, or bulb was reported in the literature. This study primarily aims to investigate the risk of complications in patients with ectopic papillae and evaluate the applicability of endoscopic sphincterotomy in these patients. Methods: In this a case-control study, the data of 3,048 patients who underwent ERCP procedure in the ERCP unit of our clinic between January 2013 and December 2018 were retrospectively analyzed, and 30 patients with ectopic bulbar papillae and 30 randomly selected patients with normally localized papillae were compared in terms of age, gender, duration of the procedure, post-procedural biochemical tests, cannulation success, precision rate, postprocedural pancreatitis complications and the need for analgesics. Power analysis was performed with the G*power 3.1.9.7 package program (1-B = 0.95, alpha = 0.05). With a power of 0.954, the sample size to be reached was thirty-three for each group. Results: The rate of pancreatitis complications was higher in patients with ectopic bulbar papillae (50%) compared to those without (16.7%) (P=0.006). Even though the rate of pre-cut was higher in patients with ectopic bulbar papillae (33.3%) compared to patients with normally localized papillae (13.3%), this difference was not statistically significant (P=0.063). Cannulation success in patients with ectopic bulbar papillae (83.3%) was insignificantly lower than in patients with normally localized papillae (90.0%) (P=0.353). The need for both narcotic and non-steroidal anti-inflammatory analgesics was higher in patients with ectopic bulbar papillae (P
