BACKGROUND Numerous types of arthroplasties may be used in the surgical treatment of a hip fracture (proximal femoral fracture). The main differences between the implants are in the design of the stems, whether the stem is fixed in place with or without cement, whether a second articulating joint is included within the prosthesis (bipolar prosthesis) or(More)
BACKGROUND This meta-analysis aimed to investigate whether preoperative biliary drainage (PBD) is beneficial to patients with obstructive jaundice. METHODS Data from randomized clinical trials related to safety and effectiveness of PBD versus no PBD were extracted by two independent reviewers. Risk ratios, rate ratios or mean differences were calculated(More)
We performed a systematic review and meta-analysis of modern total ankle replacements (TARs) to determine the survivorship, outcome, complications, radiological findings and range of movement, in patients with end-stage osteoarthritis (OA) of the ankle who undergo this procedure. We used the methodology of the Cochrane Collaboration, which uses risk of bias(More)
BACKGROUND Pancreatic resections are associated with high morbidity (30% to 60%) and mortality (5%). Synthetic analogues of somatostatin are advocated by some surgeons to reduce complications following pancreatic surgery, however their use is controversial. OBJECTIVES To determine whether prophylactic somatostatin analogues should be used routinely in(More)
BACKGROUND : In many countries laparoscopic cholecystectomy for acute cholecystitis is mainly performed after the acute episode has settled because of the anticipated increased risk of morbidity and higher conversion rate from laparoscopic to open cholecystectomy. METHODS : A systematic review was performed with meta-analysis of randomized clinical trials(More)
BACKGROUND Gallstones are present in about 10% to 15% of the adult western population. Between 1% and 4% of these adults become symptomatic in a year (the majority due to biliary colic but a significant proportion due to acute cholecystitis). Laparoscopic cholecystectomy for acute cholecystitis is mainly performed after the acute cholecystitis episode(More)
BACKGROUND Patients with obstructive jaundice have various pathophysiological changes that affect the liver, kidney, heart, and the immune system. There is considerable controversy as to whether temporary relief of biliary obstruction prior to major definitive surgery (pre-operative biliary drainage) is of any benefit to the patient. OBJECTIVES To assess(More)
BACKGROUND The main reasons for inserting a drain after elective liver resections are (i) prevention of sub-phrenic or sub-hepatic fluid collection; (ii) identification and monitoring of post-operative bleeding; (iii) identification and drainage of any bile leak; and (iv) prevent the accumulation of ascitic fluid in cirrhotics. However, there are reports(More)
BACKGROUND Surgical training has traditionally been one of apprenticeship. The aim of this review was to determine whether virtual reality (VR) training can supplement and/or replace conventional laparoscopic training in surgical trainees with limited or no laparoscopic experience. METHODS Randomized clinical trials addressing this issue were identified(More)
BACKGROUND & AIMS Transient elastography is a non-invasive method, for the assessment of hepatic fibrosis, developed as an alternative to liver biopsy. We studied the performance of elastography for diagnosis of fibrosis using meta-analysis. METHODS MEDLINE, EMBASE, SCI, Cochrane Library, conference abstracts books, and article references were searched.(More)
