BYPASS VS. SLEEVE AND ITS EFFECTS IN NON-ALCOHOLIC FATTY LIVER DISEASE: WHAT IS THE BEST TECHNIQUE?

Background: Strongly associated with obesity, non-alcoholic fatty liver disease is considered the hepatic manifestation of the metabolic syndrome. It presents as simple steatosis and steatohepatitis, which can progress to cirrhosis and its complications. Among the therapeutic alternatives is bariatric surgery.

Comparison of the severity of non-alcoholic fatty liver disease in diabetic and non-diabetic obese patients.

Introduction: nonalcoholic fatty liver disease presents a broad spectrum of histopathological alterations, from steatosis to liver cirrhosis. Patients with diabetes mellitus (DM) present increased incidence and severity of NAFLD.

Objective: determine the prevalence and severity of NAFLD in diabetic and non-diabetic obese patients undergoing bariatric surgery.

ENHANCED RECOVERY (ERAS) AFTER LIVER SURGERY:COMPARATIVE STUDY IN A BRAZILIAN TERCIARY CENTER.

Background: After the publication of the first recommendations of ERAS Society regarding colonic surgery, the proposal of surgical stress reduction, maintenance of physiological functions and optimized recovery was expanded to other surgical specialties, with minimal variations.

Aim: To analyze the implementation of ERAS protocols for liver surgery in a tertiary center.

Methods: Fifty patients that underwent elective hepatic surgery were retrospectively evaluated, using medical records data, from June 2014 to August 2016.

EARLY DRAIN FLUID AMYLASE IS USEFUL TO PREDICT PANCREATIC FISTULA AFTER PANCREATODUODENECTOMY: LESSONS LEARNED FROM A SOUTHERN BRAZILIAN CENTER.

Background: Pancreatic fistula represents the most feared complication after pancreatoduodenectomies, being the major responsible for the high morbidity and mortality after this operation. Its incidence remains around 10% to 30%. In recent years, several authors have studied the value of amylase in abdominal drains fluid, measured at an early stage after the surgical procedure, as a useful tool to identify patients at risk of developing pancreatic fistula.

Oncogenic hypophosphatemic osteomalacia: From the first signal of disease to the first signal of healthy.

Introduction: The physical incapacitation of the oncogenic hypophosphatemic osteomalacia (OHO) can be catastrophic and can lead to deformities, metabolic and organic instability and death. The only positive outcome is through early diagnosis by the clinical suspicion. At this moment, medical center infrastructure is also a keypoint.

Use of Left Gastric Vein as an Alternative for Portal Flow Reconstruction in Liver Transplantation.

Portal vein thrombosis is observed in up to 10% of liver transplant candidates, hindering execution of the procedure. A dilated gastric vein is an alternative to portal vein reconstruction and decompression of splanchnic bed. We present two cases of patients with portal cavernoma and dilated left gastric vein draining splanchnic bed who underwent liver transplantation.

AMBULATORY LAPAROSCOPIC CHOLECYSTECTOMY IS SAFE AND COST-EFFECTIVE: a Brazilian single center experience.

Background: - Laparoscopic cholecystectomy is the treatment of choice for gallstone disease, and has been perfomed as an outpatient surgery in many Institutions over the last few years.

Objective: - This is a retrospective study of a single center in Brazil, that aims to analyze the outcomes of 200 cases of ambulatory laparoscopic cholecystectomy performed by the same Hepato-Pancreato-Biliary team, evaluating the safety and cost-effectiveness of the method.

Methods: - Two hundred consecutive patients who underwent elective laparoscopic cholecystectomy were retrospectively analyzed; some of them underwent additional procedures, as liver biopsies and abdominal hernias repair.

Primitive Neuroectodermal Tumor of the Pancreas: A Case Report and Review of the Literature.

Primitive neuroectodermal tumors (PNETs) are presented as rare malignant neoplasms. In unusual cases, those neoplasms may arise in solid organs containing neuroendocrine cells, such as the pancreas. Herein the case of a 28-year-old patient that underwent gastroduodenopancreatectomy after the diagnosis of a huge mass (PNET) located in both head and body of the pancreas is reported.
