BACKGROUND & AIMS: Bariatric surgery has been reported to lead to complete resolution of nonalcoholic fatty liver disease (NAFLD) following the sustained weight loss induced in obese patients. We performed a systematic review and meta-analysis to evaluate the effects of bariatric surgery on NAFLD in obese patients. METHODS: We searched MEDLINE, EMBASE, CENTRAL, and Web of Science databases through May 2018 for studies that compared liver biopsy results before and after bariatric surgery in obese patients...

Purpose To evaluate a radiomics model for predicting lymph node (LN) metastasis in biliary tract cancers (BTCs) and to determine its prognostic value for disease-specific and recurrence-free survival. Materials and Methods For this retrospective study, a radiomics model was developed on the basis of a primary cohort of 177 patients with BTC who underwent resection and LN dissection between June 2010 and December 2016. Radiomic features were extracted from portal venous CT scans. A radiomics signature was built on the basis of reproducible features by using the least absolute shrinkage and selection operator method...

Progressive familial intrahepatic cholestasis (PFIC) is one of the causes of childhood end stage liver disease. It is an autosomal recessive disorder, characterized by pruritus, coagulopathy, growth retardation, jaundice, and subsequently cirrhosis and hepatic failure due to impaired bile acid transport and metabolism. Diversion of bile, internally or externally, from the terminal ileum, to decrease re-uptake, is a viable option for relieving pruritus. Four children with PFIC type1 were treated with partial internal biliary diversion (PIBD) from June 2014 To March 2017 in the Unit of Paediatric surgery, Jinnah Hospital Lahore...

BACKGROUND: The left renal vein (LRV) may be used for venous reconstruction during hepato-pancreato-biliary (HPB) surgery, although concerns exist about compromising renal function. This study aimed to determine renal outcomes following LRV harvest during HPB resections. METHODS: Circumferential PV/SMV resections from 2008 to 2014 were included within two groups (LRV harvest, Control). Absolute and change in Creatinine (Cr) and estimated GFR (eGFR), and rates of acute kidney injury (AKI) and chronic kidney disease (CKD), were compared...

Background: Although studies have reported on long-term (10-year) survival after hepatic resection for hepatocellular carcinoma (HCC), they did not focus on patients with hepatitis C virus (HCV)-related HCC, and the contribution of antiviral therapy to long-term survival (especially ≥15 years) has not been adequately examined. We investigated the long-term outcome after hepatic resection for HCV-related HCC, including the effects of interferon (IFN) therapy, and the changes in prognostic factors according to postoperative duration...

BACKGROUND: Auxiliary Partial Orthotopic Liver Transplantation (APOLT) in selected non-cirrhotic metabolic liver diseases (NCMLD) is a viable alternative to orthotopic liver transplantation as it supplements the function of the native liver with the missing functional protein. APOLT for NCMLD is not universally accepted due to concerns of increased technical complications and long-term graft atrophy. METHODS: Review of a prospectively collected database of all paediatric patients (age ≤16 years) who underwent liver transplant for non-cirrhotic MLD (NCMLD), from August 2009 up to June 2017 was performed...

Mechanical ventilation (MV) can augment sepsis-induced organ injury. Previous studies indicate that human mesenchymal stem cells (hMSCs) have immune-modulatory effect. We hypothesize that human adipose tissue-derived stromal cells (hADSCs) could attenuate MV and sepsis-induced organ injury. Male C57BL/6 mice were randomized to five groups: Sham group; MV group; cecal ligation and puncture (CLP) group; CLP + MV group; and CLP + MV + hADSC group. Anesthetized mice were subjected to cecal ligation and puncture surgery...

Hydatid disease or echinococcosis, a systemic zoonosis is caused by Echinococcusgranulosus larvae. This is a common disease found all over the world, especially in the Mediterranean region. We report a 40 year old male with no known comorbids who came with complaints of fever with rigors and chills, right hypochondriac pain, and yellow discolouration of the sclera. A CT scan abdomen with endoscopic retrograde cholangiopancreatography (ERCP) gave a diagnosis of hydatid cyst of the liver with pancreatitis, cholangitis and jaundice due to involvement of the biliary tree and common bile duct ERCP was done and a stent was placed after which the patient was referred to general surgery department where the resection of cyst was performed under general anaesthesia...

pLT is a highly standardized therapy for children with end-stage liver disease and liver-based metabolic diseases. However, NCs after transplantation occur and especially younger children are considered as more vulnerable and susceptible to NCs. Up to now, detailed data particularly for the very young age group do not exist. We therefore retrospectively studied NCs in children after pLT under age of 24 months. Forty children aged between 19 days and 22 months were evaluated according to type of NC and potential risk factors...

BACKGROUND: Several reported complications associated with radiofrequency ablation for liver tumors are due to thermal damage of neighboring organs. We herein report a first case of esophageal perforation due to thermal injury of laparoscopic radiofrequency ablation (RFA). CASE PRESENTATION: A 75-year-old woman was treated repeatedly with RFA (percutaneous and laparoscopic) and transcatheter arterial chemoembolization for hepatocellular carcinoma. One week after laparoscopic RFA for recurrent HCC located in segment 2 of the liver, dysphagia and thoracic pain occurred...

BACKGROUND: Fluid and pain management during liver surgery (eg, low central venous pressure) is a classic topic of controversy between anesthesiologists and surgeons. Little is known about practices worldwide. The aim of this study was to assess perioperative practices in liver surgery among and between surgeons and anesthesiologists worldwide that could guide the design of future international studies. METHODS: An online questionnaire was sent to 22 societies, including 4 international hepatopancreatobiliary societies, the American Society of Anesthesiologists, and 17 other (inter-)national societies...

BACKGROUND: Whether non-colorectal non-neuroendocrine liver metastasis (NCNNLM) should be treated surgically remains unclear. METHODS: Data regarding 1639 hepatectomies performed between 2001 and 2010 for 1539 patients with NCNNLM were collected from 124 institutions. Patient characteristics, types of primary tumor, characteristics of liver metastases, and post-hepatectomy outcomes were analyzed. RESULTS: The 5 most frequent primary tumors were gastric carcinoma (540 patients [35%]), gastrointestinal stromal tumor (204 patients [13%]), biliary carcinoma (150 patients [10%]), ovarian cancer (107 patients [7%]), and pancreatic carcinoma (77 patients [5%])...

Celiac trunk is the artery of foregut, arising from the abdominal aorta at the level of T12/L1 vertebral body. It extends approximately 1.5 to 2 cm horizontally forwards before dividing into three branches: left gastric, common hepatic, and splenic arteries. Out of the three ventral branches of abdominal aorta, celiac trunk is more prone to have variations. During routine dissection of abdomen for undergraduate students we found some rare variations in the branching pattern of the celiac trunk. Absence of celiac trunk with hepatomesenteric trunk, quadrifurcation with dorsal pancreatic artery arising from it, quadrifurcation with middle colic artery arising from it, left inferior phrenic artery arising from celiac trunk, highly tortuous splenic artery supplying distal 1/3rd of transverse colon and hepatosplenic trunk...

Acute kidney injury (AKI) is a frequent postoperative complication after liver transplantation. The etiology is multifactorial, including perioperative renal status, surgery related events, and postoperative immunosuppression therapy. The role of renal hypoperfusion and hepatic ischemia-reperfusion injury as causes of early AKI are now being increasingly recognized. Further studies should focus on therapies that would attenuate this injury.
