An Early Prospective Clinical Study to Evaluate the Safety and Performance of the Versius Surgical System in Robot-Assisted Cholecystectomy.

Objective: The aim of this study was to demonstrate the ability of the Versius Surgical System to successfully and safely complete cholecystectomy.

Background: The system has been developed in-line with surgeon feedback to overcome limitations of conventional laparoscopy to enhance surgeon experience and patient outcomes. Here we present results from the cholecystectomy cohort from a completed early clinical trial, which was designed to broadly align with Stage 2b of the Idea, Development, Exploration, Assessment, Long-term follow-up framework for surgical innovation.

Cronkhite Canada syndrome complicated by pulmonary embolism-A case report.

Introduction: Cronkhite Canada Syndrome (CCS) is a rare syndrome, described in 1955 by Americans, Leonard Wolsey Cronkhite and Wilma Jeanne Canada in the New England Journal of Medicine [1]. About 450 cases have been reported. Complications, like malignant transformation, unprovoked thromboembolism is known.

Pre-transplant optimization by Molecular Adsorbent Recirculating System in patients with severely decompensated chronic liver disease.

Background: The outcome of liver transplantation (LT) is influenced by the recipient's clinical condition. In a retrospective observational study, we evaluated the role of pre-LT Molecular Adsorbent Recirculating System (MARS) treatment in improving the clinical status and thereby the outcome of patients with chronic liver disease and severe hepatic decompensation.

Methods: Between March 2002 and September 2006, 70 patients with end-stage chronic liver disease underwent living-donor LT (LDLT).

Spontaneous perforation--a rare complication of choledochal cyst.

We report a 2-year-old girl with spontaneous perforation of choledochal cyst. Preoperative diagnosis was possible by hepatobiliary scintigraphy. In view of emergency presentation and bile peritonitis, management was a staged procedure with peritoneal lavage and T-tube drainage of the biliary system, followed by excision of the cyst and Roux-en-Y hepatico-jejunostomy 3 months later.

Bouveret's syndrome--an unusual cause of spontaneous resolution of gastric outlet obstruction.

Gastric outlet obstruction due to a gallstone impacted in the duodenal bulb (Bouveret's syndrome) is a rare complication of gallstones. We report a 47-year-old man with this syndrome in whom the impacted stone migrated uneventfully.

Morphological changes in bile ducts following preoperative biliary stenting.

Objectives: To analyze the morphological changes in bile ducts following endobiliary stent insertion, and consequent technical problems encountered at surgery.

Methods: Data on bile duct morphology--gross (luminal diameter and wall thickness) and microscopic (histological changes in bile duct wall graded semiquantitatively)--and operative parameters related to bile duct dissection (grade of difficulty in dissection) were collected prospectively in 31 consecutive patients undergoing pancreatico-duodenectomy. These data were compared between patients who had undergone preoperative endoscopic biliary stent placement (n=17) and those who had not (n=14).

Dieulafoy's lesion of duodenum: a case report.

Background: Dieulafoy's lesion is an uncommon but important cause of recurrent upper gastrointestinal bleeding. Extragastric location of Dieulafoy's lesion is rare. We report two cases of Dieulafoy's lesion of the duodenum and discuss the management of this extremely uncommon entity.

Longterm survival after extended resections in patients with gallbladder cancer.

Background: Surgery is the treatment of choice for gallbladder cancer, but the extent of resection and its benefits remain unclear.

Study Design: Survival analysis of 42 patients who underwent extended resections for gallbladder cancer was performed. Resections were labeled R0 (curative) or R1 (noncurative) based on histopathologic evaluation.

Large Brunneroma presenting with bleeding.

Brunner's gland adenoma (Brunneroma) is a rare entity. We report a patient who presented with severe anemia due to bleed from a large Brunneroma arising from the duodenal bulb, and was managed successfully by surgical excision of the tumor.

Early gallbladder cancer.

Background: The majority of patients with gallbladder cancer (GBC) have advanced disease at the time of diagnosis and are unresectable. Longterm survival is usually seen in a subset of patients with early GBC (EGBC)-cancer confined to the mucosa (pT1a) and muscularis (pT1b). Management guidelines of EGBC are not yet defined and are controversial.
