RESUMO
OBJECTIVE: In this retrospective study, we compared the postoperative complications by using both the Clavien-Dindo classification and the Revised 2016 International Study Group on Pancreatic Surgery (ISGPS) classification methods after pancreaticoduodenectomy. MATERIALS AND METHODS: The data of patients were retrospectively reviewed. Pancreaticojejunostomy (PJ) and pancreaticogastrostomy (PG) were performed on 41 and 40 patients, respectively. The patients were assigned into two groups for anastomosis types and compared with each other according to postoperative complications. The postoperative follow-up period of the patients was limited to 90 days. RESULTS: No significant difference was detected between the two groups in terms of gender (P = .581) and age (P = .809). According to the Clavien-Dindo classification system, grade 1 complication rates were 29.3% and 35.0% in PJ and PG groups, respectively. Also, grade 2 complication rates were 34.1% and 32.5% in PJ and PG groups, respectively. Besides, grade 3B complication rates were 9.8% and 17.5% in PJ and PG groups, respectively. No grade 3A, grade 4A, and grade 4B complications were detected in both groups. But, grade 5 complications rates were 2.4% and 5.0% in PJ and PG groups, respectively. Based on the ISGPS classification system, the pancreatic fistulas were classified. The biochemical leak rates were calculated as 26.8% and 37.5% in PJ and PG groups, respectively. The rates were 14.6% and 10% in PJ and PG groups, respectively, for grade B complications. Also, grade C complication rates were 9.75% and 12.5% in PJ and PG groups, respectively. No statistically significant differences were detected between the two groups for postoperative complications. CONCLUSION: The evidence from this retrospective study suggests that there is no difference between the two types of pancreatic anastomosis techniques (PJ or PG) in terms of the rate of postoperative complications.
RESUMO
PURPOSE: Liver transplantation is a curative treatment option for hepatocellular carcinoma. In this review, we aimed to review liver transplantation criteria for hepatocellular carcinoma and patient survivals. METHODS: We reviewed literature in terms of liver transplant criteria for hepatocellular carcinoma. Patient eligibility criteria, post-transplant survivals, tumor recurrence and expansion of Milan criteria rates were analyzed. RESULTS: The Milan criteria, after being published in 1996, have become for deceased donor liver transplantation in hepatocellular carcinoma worldwide. Later, many transplant centers published their own liver transplant criteria. Most of the criteria consisted of morphological tumor characteristics based on tumor size and number. The newest published one is Malatya criteria. The 5-year overall survival according the all of the criteria is greater than 50%. There were just one paper which compare criteria according to survival and Malatya criteria were the best amongst extended criteria with 5-year OS 79.7% in that study. CONCLUSION: It is clear that morphological criteria consisting only of tumor size and number are insufficient in patient selection for liver transplantation and should thus be combined with biological, inflammatory, radiological, pathological and genetic markers that predict the biological behavior of the tumor. Efforts to find the best criteria are still ongoing and 5-year overall survival should be greater than 60%.

RESUMO
Survival was examined from a Turkish liver transplant center of patients with HCC, to identify prognostic factors. Data from 215 patients who underwent predominantly live donor liver transplant for HCC at our institute over 12 years were included in the study and prospectively recorded. They were 152 patients within and 63 patients beyond Milan criteria. Patients beyond Milan criteria were divided into two groups according to presence or absence of tumor recurrence. Recurrence-associated factors were analyzed. These factors were then applied to the total cohort for survival analysis. We identified four factors, using multivariate analysis, that were significantly associated with tumor recurrence. These were maximum tumor diameter, degree of tumor differentiation, and serum AFP and GGT levels. A model that included all four of these factors was constructed, the 'Malatya criteria.' Using these Malatya criteria, we estimated DFS and cumulative survival, for patients within and beyond these criteria, and found statistically significant differences with improved survival in patients within Malatya criteria of 1, 5, and 10-year overall survival rates of 90.1%, 79.7%, and 72.8% respectively, which compared favorably with other extra-Milan extended criteria. Survival of our patients within the newly defined Malatya criteria compared favorably with other extra-Milan extended criteria and highlight the usefulness of serum AFP and GGT levels in decision-making.

Fibrolamellar hepatocellular carcinoma is a rare primary malignant liver neoplasm. Benefits from liver transplant for patients with fibrolamellar hepatocellular carcinoma have not yet been reported. Here, we report a 19-year-old female patient who presented with abdominal pain. A computed tomography scan revealed bilobar and multiple solid lesions with the largest measuring 15 cm in diameter on the right lobe of her liver. Her blood alpha-fetoprotein level and viral hepatitis markers were normal. A fine-needle biopsy of the largest lesion detected fibrolamellar heptocellular carcinoma. Because no distant metastasis was evident and the carcinoma was unresectable, a right lobe living-donor liver transplant with hilar lymph node dissection was performed. A pathology report revealed poorly differentiated fibrolamellar hepatocellular carcinoma, and further testing indicated microvascular invasion and hilar lymph node metastasis. The largest tumor measured 12 cm. She was discharged on postoperative day 14. During postoperative month 22, multiple vertebral metastases were detected, and she died with diffuse metastasis during postoperative month 26. Our patient, with poor prognostic criteria such as hilar lymph node metastasis, microvascular invasion, and poor differentiation, had 22 months of tumor-free survival and 26 months of overall survival after having undergone living-donor liver transplant.
RESUMO
Reconstruction of anomalous portal vein branching (APVB) during right lobe living donor liver transplantation (LDLT) can be challenging. The goal of this article is to describe our surgical technique, named the Malatya Approach, in case of APVB during right lobe LDLT. The technique unifies the APVB and obtains a funnel-shaped common extension with a circumferential fence by a saphenous vein conduit. In total, 126 (10.6%) of 1192 right lobe grafts had APVB that were divided into 2 groups according to the adopted surgical techniques: the Malatya Approach group (n = 91) and the previously defined other techniques group (n = 35). Both groups were compared regarding portal vein thrombosis (PVT), postoperative 90-day mortality and survival. PVT developed in 3 patients (3.3%) in the Malatya Approach group and developed in 10 (28.6%) patients for the other group (P < 0.001). There were 8 (8.8%) 90-day mortalities in the Malatya Approach group (1 PVT related) and 15 patients (9 PVT related) died in the other techniques group (P < 0.001). Mean follow-up time for both groups was similar (999.1 days for the Malatya Approach group versus 1024.7 days for the other group; P = 0.47), but longterm survival in the Malatya Approach group was better than in the other group (84.6% versus 40%; P < 0.001). Multivariate analysis revealed that the Malatya Approach group showed less PVT development and longer survival (P < 0.001). This technique is promising to avoid PVT and mortalities in cases of APVB during right lobe LDLT. Liver Transplantation 23 751-761 2017 AASLD.

BACKGROUND: The aim of the study was to report the detailed surgical techniques of living donor liver transplantation (LDLT) in patients with Budd-Chiari syndrome (BCS). METHODS: Demographic and surgical techniques characteristics of 39 patients with BCS who underwent LDLT were retrospectively reviewed. Thirty-two of them had native vena cava inferior (VCI) preservation and 6 had retrohepatic VCI resection with venous continuity established by cryopreserved VCI (n = 4) or aortic graft (n = 2). In 1 patient, the anastomosis was established between the graft hepatic vein (HV) and the suprahepatic VCI. For preservation of the native VCI, immediately before the graft implantation, the thickened anterior, and right/left lateral walls of the recipient VCI were resected caudally and cranially until the intact vein wall was reached, and then an anastomosis was created between the (HV) of the graft reconstructed as a circumferential fence and the reconstructed recipient VCI. For resection of the retrohepatic VCI, the anastomosis was created with the same technique in all 6 patients in whom VCI was reformed by using a vascular graft. RESULTS: Post-LT complications developed in 19 of the patients. Complications related to the biliary anastomosis accounted for 12 of these cases, with 11 treated by PTC and/or ERCP, and 1 by hepaticojejunostomy. Two of the 39 patients developed recurrent BCS and were treated by interventional radiological methods. Thirteen patients died and none were related to the BCS recurrence. CONCLUSION: Favorable outcomes are achievable with LDLT treatment of patients with BCS, which carries important implications for countries with inadequate cadaveric donor pools.

OBJECTIVES: Although the main factors responsible for donor deaths after living-donor liver transplant are liver failure and sepsis, the most common donor complications are associated with the biliary tract. MATERIALS AND METHODS: Between April 2006 and May 2012, five hundred ninety-three donors underwent living-donor hepatectomy procedures for living-donor liver transplants. The mean age of donors was 31.0 ± 9.9 years and the ratio of men to women was 341:252. Of all donors, 533 (89.9%) underwent a right lobe hepatectomy, 45 (7.6%) underwent a left lateral segmentectomy, and 15 (2.5%) underwent a left hepatectomy. RESULTS: Biliary complications were observed in 51 liver donors (8.6%). Based on the Clavien-Dindo classification, grade I and grade II complications were 3.2% and 0%, while grade IIIa and grade IIIb complications were observed in 3.5% and 1.85% of cases. Right lobe donor biliary complications occurred at the rate of 8.2% in 44 donors. Grade IV and grade V complications were not observed. Grade IIIa complications necessitating radiologic and endoscopic procedures were observed in 21 liver donors (3.5%). Bile leakage unresponsive to medical therapy was detected in 19 donors (3.2%). Nasobiliary catheters were placed in 3 of 19 donors and internal stents were placed in 1. Two sessions of balloon dilatation were performed in the 2 grade IIIb donors (0.33%). Biliary strictures observed in 2 right lobe donors and 1 left lobe donor was treated by hepaticojejunostomy an average of 14 months after surgery. CONCLUSIONS: Avoidance of intraoperative issues and early recognition of bile leakage are fundamental in preventing complications in living-donor liver transplant donors.

Progressive liver failure is rarely seen in tuberculosis chemoprophylaxis with isoniazid. We present a case of a 32-year-old woman admitted to our clinic reporting abdominal pain, nausea and vomiting for 2 days. The initial diagnosis was fulminant toxic hepatitis due to isoniazid chemoprophylaxis, which was treated successfully with living donor transplantation. Tuberculosis continues to be a significant public health problem. Isoniazid-related hepatotoxicity is extremely rare in adults. The only treatment in cases of fulminant liver failure is orthotopic liver transplantation from a deceased or living donor. If a deceased donor is not available or the patient refuses this treatment, living donor transplantation is the only choice. Although rare, isoniazid used as protective therapy for pulmonary tuberculosis can lead to fulminant liver failure. When cadaveric liver transplantation is not available, living donor liver transplantation is vital.

INTRODUCTION: Endoscopic esophageal stent placement is used to treat benign strictures, esophageal perforations, fistulas and for palliative therapy of esophageal cancer. Although stent placement is safe and effective method, complications are increasing the morbidity and mortality rate. We aimed to present a patient with small bowel perforation as a consequence of migrated esophageal stent. PRESENTATION OF CASE: A 77-years-old woman was admitted with complaints of abdominal pain, abdominal distension, and vomiting for two days. Her past medical history included a pancreaticoduodenectomy for pancreatic tumor 11 years ago, a partial esophagectomy for distal esophageal cancer 6 months ago and an esophageal stent placement for esophageal anastomotic stricture 2 months ago. On abdominal examination, there was generalized tenderness with rebound. Computed tomography showed the stent had migrated. Laparotomy revealed a perforation localized in the ileum due to the migrated esophageal stent. About 5cm perforated part of gut resected and anastomosis was done. The patient was exitus fifty-five days after operation due to sepsis. DISCUSSION: Small bowel perforation is a rare but serious complication of esophageal stent migration. Resection of the esophagogastric junction facilitates the migration of the stent. The lumen of stent is often allow to the passage in the gut, so it is troublesome to find out the dislocation in an early period to avoid undesired results. In our case, resection of the esophagogastric junction was facilitated the migration of the stent and late onset of the symptoms delayed the diagnosis. CONCLUSION: Patients with esophageal stent have to follow up frequently to preclude delayed complications. Additional technical procedures are needed for the prevention of stent migration.
RESUMO
INTRODUCTION: Alveolar echinococceal disease of the liver is rare. Echinococcus multilocularis is responsible for the development of the related clinical conditions. Advanced disease may result with serious complications such as end stage liver disease and Budd-Chiari syndrome. PRESENTATION OF CASE: In this presentation, a 28 years-old woman who was a case with advanced alveolar echinococcosis complicated with a Budd-Chiari syndrome and was performed successful living donor liver transplantation, has been demonstrated with clinical and radiological images. DISCUSSION: Initially there may be no clinical evidence of the disease in humans for years. Severity and fatality are the significant characteristics of the natural history. Extension to the surrounding tissues and metastasis of the parasitic mass may be observed. Prevention is essential in disease control. Serologic assay may identify the parasite. However, early diagnosis is rare. Staging is based on radiologic imaging. Some patients with advanced disease may require surgery. Hepatic resection and liver transplantation are accepted procedures in selected patients. CONCLUSION: The importance of early diagnosis to prevent advanced complications such as development of Budd-Chiari syndrome and metastasis has been underlined.
RESUMO
AIM: To investigate the prevalence and implications of unusual histopathological findings in appendectomy specimens from patients with suspected acute appendicitis. METHODS: The demographic and histopathological data of 1621 patients (≥ 16 years-old) who underwent appendectomy to treat an initial diagnosis of acute appendicitis between January 1999 and November 2011 were retrospectively assessed. Microscopic findings were used to classify the patients under six categories: appendix vermiformis, phlegmonous appendicitis, gangrenous appendicitis, perforated appendicitis, supurative appendicitis, and unusual histopathologic findings. The demographic and clinicopathologic characteristics of patients with unusual histopathologic findings were evaluated in detail, and re-analysis of archived resected appendix specimens was carried out. RESULTS: A total of 912 males and 709 females, from 16 to 94 years old, were included in the study and comprised 789 cases of suppurative appendicitis, 370 cases of appendix vermiformis, 243 cases of perforated gangrenous appendicitis, 53 cases of flegmaneous appendicitis, 32 cases of gangrenous appendicitis, and 134 (8.3%) cases of unusual histopathological findings. The unusual histopathological findings included fibrous obliteration (n = 62), enterobius vermicularis (n = 31), eosinophilic infiltration (n = 10), mucinous cystadenoma (n = 8), carcinoid tumor (n = 6), granulomatous inflammation (n = 5), adenocarcinoma (n = 4; one of them mucinous), and mucocele (n = 3), adenomatous polyp (n = 1), taenia sup (n = 1), ascaris lumbricoides (n = 1), appendiceal diverticula (n = 1), and B cell non-hodgkin lymphoma (n = 1). None of the 11 patients with subsequent diagnosis of tumor were suspected of cancer prior to the appendectomy. CONCLUSION: Even when the macroscopic appearance of appendectomy specimens is normal, histopathological assessment will allow early diagnosis of many unusual diseases.

BACKGROUND/AIMS: ABO-incompatible (ABO-I) liver transplantation (LTx) may be mandatory in urgent conditions such as acute liver failure (ALF) or acute-on-chronic liver failure (ACLF) when deceased donor (DD) is unavailable or living donor (LD) selection is limited. This study specifically addresses the problem of urgent ABO-I LTx in critically ill adult patients having ALF or severely decompensated end-stage liver disease. METHODOLOGY: This series included 16 patients, 10 underwent ABO-I LD LTx and 6 underwent 7 ABO-I DD LTx. Multiple sessions of plasmapheresis reduced isoaglutinin titres to 1/16 or below, before and after LTx. RESULTS: Mean follow-up period was 10.37 months (1 to 38). Median for MELD scores was 22.5 (17 to 30). Median survival was 9 months and mean survival was 19.5 months. Hospital mortality was 3 (18.7%). Two patients died due to small for size graft syndrome and cerebrovascular bleeding respectively. Hepatic artery thrombosis developed in 3 patients. Two of them died at postoperative 4th and 9th months. Third patient is still alive with hepatic necrosis problem. CONCLUSIONS: ABO-I LTx remains an important and unavoidable therapeutic option in adult patients with ALF or ACLF and urgent need for an allograft without the possibility to allocate a blood group compatible liver graft.

BACKGROUND/AIMS: Living donor liver transplantations (LDLT) is a definitive treatment for patients with end-stage liver disease (ESLD), especially in the countries with donation problem. Between April 2007 and April 2010, we performed LDLT in 289 patients. Fifteen of the cases required re-transplantations. This study evaluates these 304 consecutive LDLTs donor and recipient outcomes. METHODOLOGY: Complication rates and survival data of the recipients and donors of 304 LDLT cases were analyzed. RESULTS: All donors are alive and well. Overall complication rate was 27%. Early postoperative recipient complication rate was 51%. Most frequent complication was infection. In the long-term there were 57 biliary stricture and 5 chronic bile fistula cases. Chronic and acute rejection attacks developed in 7 and 103 patients, respectively. Hepatic artery thrombosis rate was 8%. One, two and three year survival rates were 82%, 79% and 75%, respectively. Recipient mortality was 25%, mostly due to vascular complications, septic complications, liver dysfunction and chronic rejection. CONCLUSIONS: More than 150 liver tranplantations per year in a single center is a challenge in Turkey, where there is a shortage of deceased donor grafts. LDLT is a safe procedure for donors and effective for ESLD. Improvement in surgical technique would provide better outcomes.

BACKGROUND: Laparoscopic appendectomy is a well-described surgical technique. However, concerns still exist regarding whether the closure of the appendiceal stump should be done with a clip, an endoloop, staples, or other techniques. Therefore, several modifications to the original technique with new materials have been introduced for appendiceal stump closure. The aim of this study was to compare intracorporeal (polyglactin) knot-tying suture with titanium endoclips in appendiceal stump closure during laparoscopic appendectomy. METHODS: The study was carried out as a prospective randomized clinical trial between April 2010 and February 2011. Patients with a presentation of appendicitis were included into the study. Two groups were defined-patients with the titanium endoclip and patients with the knot-tying (polyglactin) suture. The results in terms of operating time, complication rates, and hospital stay were analyzed. RESULTS: Sixty-one patients who underwent laparoscopic appendectomy were enrolled in the titanium endoclip group (n=30) or the knot-tying (polyglactin) suture group (n=31). No statistically significant differences were detected between the groups in terms of the distribution of age, sex percentage, appendix localization, and histopathologic diagnosis (P>0.05). One patient required a second operation on postoperative day 10 because of intraperitoneal abscess. The mean operative time for the endoclip group (41.27 ± 12.2 min) was shorter than that for the knot-tying group (62.81 ± 15.4 min) (P=0.001). No statistically significant differences were detected between the groups in terms of hospital stay, follow-up time, and preoperative and postoperative complications (P>0.05). CONCLUSIONS: In laparoscopic appendectomy, using a titanium endoclip for optimizing and controlling the appendiceal stump closure is safe and is associated with shorter operation time. This also simplifies the procedure, so it can be a useful alternative to intracorporeal knot-tying for appendiceal stump closure.

In this study, we evaluated the diagnosis, epidemiology, risk factors, and treatment of chylous ascites developing after liver transplantation (LT). Between 2002 and 2011, LT was performed 693 times in 631 patients at our clinic. One-hundred fifteen of these patients were excluded for reasons such as retransplantation, early postoperative mortality, and insufficient data. Chylous ascites developed after LT (mean ± SD = 8.0 ± 3.2 days, range = 5-17 days) in 24 of the 516 patients included in this study. Using univariate and multivariate analyses, we examined whether the following were risk factors for developing chylous ascites: age, sex, body mass index, graft-to-recipient weight ratio, Model for End-Stage Liver Disease score, vena cava cross-clamping time, total operation time, Child-Pugh classification, sodium level, portal vein thrombosis or ascites before transplantation, donor type, albumin level, and perihepatic dissection technique [LigaSure vessel sealing system (LVSS) versus conventional suture ligation]. According to a univariate analysis, a low albumin level (P = 0.04), the presence of ascites before transplantation (P = 0.03), and the use of LVSS for perihepatic dissection (P < 0.01) were risk factors for developing chylous ascites. According to a multivariate Cox proportional hazards model, the presence of pretransplant ascites [P = 0.04, hazard ratio (HR) = 2.8, 95% confidence interval (CI) = 1.1-13.5] and the use of LVSS for perihepatic dissection (P = 0.01, HR = 5.4, 95% CI = 1.5-34.4) were independent risk factors. In conclusion, the presence of preoperative ascites and the use of LVSS for perihepatic dissection are independent risk factors for the formation of chylous ascites. To our knowledge, this study is the most extensive examination of the development of chylous ascites. Nevertheless, our results should be supported by new prospective trials.

Yellow phosphorus is a protoplasmic toxicant that targets the liver. The ingestion of fireworks containing yellow phosphorus, either by children who accidentally consume them or by adults who are attempting suicide, often results in death due to acute liver failure (ALF). We present the outcomes of 10 children who ingested fireworks containing yellow phosphorus. There were 6 boys and 4 girls, and their ages ranged from 21 to 60 months. One patient remained stable without liver complications and was discharged. Three patients died of hepatorenal failure and cardiovascular collapse, and living donor liver transplantation (LDLT) was performed for 6 patients. The patients had grade II or III encephalopathy, a mean alanine aminotransferase level of 1148.2 IU/L, a mean aspartate aminotransferase level of 1437.5 IU/L, a mean total bilirubin level of 6.9 mg/dL, a mean international normalized ratio of 6.6, a mean Pediatric End-Stage Liver Disease score of 33.7, and a mean Child-Pugh score of 11.3. Postoperatively, 2 patients had persistent encephalopathy and died on the second or third postoperative day, and 1 patient died of cardiac arrest on the first postoperative day despite a well-functioning graft. The other 3 patients were still alive at a mean of 204 days. In conclusion, the ingestion of fireworks containing yellow phosphorus causes ALF with a high mortality rate. When signs of irreversible ALF are detected, emergency LDLT should be considered as a lifesaving procedure; however, if yellow phosphorus toxicity affects both the brain and the heart in addition to the liver, the mortality rate remains very high despite liver transplantation.

BACKGROUND: Nephrotoxicity is an important side effect of FK506 and oxidative stress has been considered as one of the possible mechanisms. The present investigation examines the ability of melatonin to protect against FK506-induced renal oxidative stress. METHODS: Thirty rats were divided into 3 groups (n = 10 each group). Group A was the sham group. Group B received 14 days FK506 (5 mg/kg/d, intraperitoneally [i.p.]) and group C received FK506 (5 mg/kg/d, i.p.) together with melatonin (4 mg/kg, i.p.) for 14 days. Kidney tissues were harvested to determine the tissue levels of malondialdehyde (MDA), total nitrite and nitric oxide (NO), tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6). RESULTS: In group C, the levels of TNF-α, IL-6, and NO were lower than in the group B (P < .01, P < .03, and P < .04, respectively) and although MDA levels were lower than in group B, the differences were not statistically significant (P > .05). CONCLUSION: These results suggest that melatonin has protective effect against FK506-induced renal oxidative stress.

Recently the authors have reported the potent beneficial effect of caffeic acid phenethyl ester (CAPE) on cholestatic oxidative liver injury induced by acute bile ligation in Swiss albino rats. Herein, they report the ultrastructural hepatocellular alterations induced by acute bile duct ligation and the effect of CAPE administration on these alterations. Bile duct ligation resulted in many degenerative changes, such as vacuolization, mitochondrial degeneration, endoplasmic reticulum dilatation, and lysosome accumulation within the cytoplasm of hepatocytes. Mitochondrial degeneration was also observed within the cytoplasm of the cells of biliary ductular epithelium. CAPE potentially protected the hepatocytes from the cholestasis-induced cellular injury.

Small bowel perforation is a rare complication of femoral artery access in cases of femoral hernia. A 48-year-old woman was admitted to the intensive care unit due to pulmonary insufficiency. After a routine femoral arterial blood gas analysis, severe abdominal pain and nausea began. She underwent emergency laparotomy due to acute abdomen. Laparotomy revealed small bowel perforation. Segmental resection and end-to-end anastomosis were performed. The femoral canal was closed using plaque mesh. Special attention is needed during femoral artery access to avoid accidental small bowel perforation. As seen in this case, a careful examination should be done in cases of femoral hernia.
