Resection of biliary mucinous cystic neoplasms: Study of a single institutional cohort and a literature reviewKloppers, Jacobus Christoffel January 2017 (has links)
Background: Biliary mucinous cystic neoplasms (BMCNs) are uncommon neoplastic septated intrahepatic cysts which are often incorrectly diagnosed and have the potential for malignant transformation. Aim: The aim of this study was to assess the outcome of surgical resection of BMCNs. Methods: Data from a departmental and faculty registered prospective liver surgery database was used to identify patients who underwent surgery at Groote Schuur and the University of Cape Town Private Academic Hospitals for BMCN from 1999 to 2015. Standard demographic variables including age and gender were documented as well as detailed preoperative imaging, location and size, operative treatment, extent of resection, histology, post-operative complications using the Clavien-Dindo classification and long-term outcome. Results: Thirteen female patients (median age 45 years) had surgery. Eleven were diagnosed by computer tomography scan after investigation of abdominal pain or a palpable mass. Two were jaundiced. One cyst was found incidentally during an elective cholecystectomy. Five cysts were located centrally in the liver. Before referral three cysts were treated inappropriately with percutaneous aspiration or drainage and two were treated with operative deroofing. Six patients had anatomical liver resections and seven patients had non anatomical liver resections of which two needed ablation of residual cyst wall. One patient needed a biliary-enteric reconstruction to treat a fistula of the left hepatic duct. Median operative time was 183 minutes (range: 130-375). No invasive carcinoma was found on histology. There was no operative mortality. One surgical site infection was treated and one patient developed an intra-abdominal collection one month post-operatively. Two patients developed recurrent BMCN after 24 months. Conclusion: BMCNs should be considered in middle aged women who have well encapsulated multilocular liver cysts. Treatment of large central BMCNs adjacent to vascular and biliary structures in particular may require technically complex liver resections and are best managed in a specialized hepato-pancreatico-biliary unit.

A cost analysis of operative repair of major laparoscopic bile duct injuriesHofmeyr, Stefan January 2015 (has links)
Includes bibliographical references / Major bile duct injuries occur infrequently after laparoscopic cholecystectomy but may result in life-threatening complications. Few data exist about the financial implications of bile duct repair. This study calculated the total inhospital costs of operative repair in a cohort of patients who underwent reconstruction of the bile duct after major ductal injury sustained during laparoscopic cholecystectomy. A prospective database was reviewed to identify all patients referred to the University of Cape Town Private Academic Hospital between 2002 and 2013 for assessment and repair of major laparoscopic bile duct injuries. The detailed clinical records and billing information were evaluated to determine all costs from admission to discharge. Total costs for each patient were adjusted for inflation between the year of repair and 2013. Forty four patients (33 women, 11 men, median age 48 years, range 30 - 78) underwent reconstruction of a major bile duct injury. First time repairs were performed at a median of 24.5 days (range 1 - 3662) after initial surgery. Median hospital stay was 15 days (range 6-86). Mean cost of repair was R215 711 (range R68 764 - 980 830). Major contributors to cost were theatre expenses (22%), admission to intensive care (21%), radiology (17%) and specialist fees (12%). Admission to a general ward (10%), consumables (7%), pharmacy (5%), endoscopy (3%) and laboratory costs (3%) made up the balance. The cost of repair of a major laparoscopic bile duct injury is substantial due to prolonged admission to hospital, complex surgical intervention and intensive imaging requirements.

A prospective randomised trial comparing plastic and uncovered self-expanding metal stents for palliation of symptomatic jaundice in patients with malignant distal biliary obstructionBernon, Marc Michael January 2017 (has links)
The aim of this study was to determine the safety and clinical effectiveness of 10Fr plastic biliary stents compared to uncovered self-expanding metal stents (SEMS) for palliative treatment of patients with inoperable malignant distal biliary obstruction in a public hospital in South Africa. Methods: From January 2009 to December 2013, 40 patients who were admitted to a tertiary academic centre because of distal malignant biliary obstruction were enrolled in a prospective randomised study. Patients were randomly assigned to receive either an uncovered SEMS or a plastic stent deployed through the biliary stricture during endoscopic retrograde cholangiopancreatography. Results: Patient survival time in the two groups did not differ significantly (median: SEMS - 114 days; plastic - 107 days) (p=0.181). Stent failure was more common in the plastic stent group (7/19 vs. 1/20) (p=0.043). The results became significant after 6 months of follow up. There was no significant difference between the two groups in the incidence of serious adverse events. Conclusions: SEMS had a longer duration of patency than plastic stents, which favours their use in the palliative treatment of patients with biliary obstruction due to distal malignant biliary obstruction.
