BACKGROUND Infectious complications and associated mortality are a major concern in acute pancreatitis. Enteral administration of probiotics could prevent infectious complications, but convincing evidence is scarce. Our aim was to assess the effects of probiotic prophylaxis in patients with predicted severe acute pancreatitis. METHODS In this multicentre(More)
BACKGROUND In recent years the Enhanced Recovery after Surgery (ERAS) postoperative pathway in (ileo-)colorectal surgery, aiming at improving perioperative care and decreasing postoperative complications, has become more common. OBJECTIVES We investigated the effectiveness and safety of the ERAS multimodal strategy, compared to conventional care after(More)
BACKGROUND Necrotizing pancreatitis with infected necrotic tissue is associated with a high rate of complications and death. Standard treatment is open necrosectomy. The outcome may be improved by a minimally invasive step-up approach. METHODS In this multicenter study, we randomly assigned 88 patients with necrotizing pancreatitis and suspected or(More)
BACKGROUND Cholecystectomy is one of the most frequently performed operations. Open cholecystectomy has been the gold standard for over 100 years. Laparoscopic cholecystectomy was introduced in the 1980s. OBJECTIVES To compare the beneficial and harmful effects of laparoscopic versus open cholecystectomy for patients with symptomatic cholecystolithiasis.(More)
BACKGROUND Preliminary experience has suggested that preperitoneal mesh positioning causes less chronic pain than Lichtenstein's technique for inguinal hernia repair. Therefore, a randomized clinical trial was conducted with the aim of evaluating the incidence of postoperative chronic pain after transinguinal preperitoneal (TIPP) mesh repair versus(More)
OBJECTIVE To analyze the literature of ileal pouch anal anastomosis (IPAA) regarding complications and functional outcome, to provide audit data for individual surgeons and units to assess their own performance against and also to serve as reference standard for the assessment of novel alternatives. BACKGROUND IPAA is the standard restorative procedure(More)
BACKGROUND Restorative proctocolectomy with ileo pouch anal anastomosis (IPAA) is the main surgical treatment for patients with ulcerative colitis (UC) and familial adenomatous polyposis (FAP). With the advancements of minimal-invasive surgery this demanding operation is increasingly being performed laparoscopically. Therefore, the presumed benefits of the(More)
BACKGROUND & AIMS Treatment of patients with necrotizing pancreatitis has become more conservative and less invasive, but there are few data from prospective studies to support the efficacy of this change. We performed a prospective multicenter study of treatment outcomes among patients with necrotizing pancreatitis. METHODS We collected data from 639(More)
In a prospective, randomised trial of 81 patients with fractures of the ankle of AO types A, B and C we compared two regimes of postoperative management after internal fixation. The patients were mobilised either non-weight-bearing with crutches or weight-bearing in a below-knee walking plaster. We found a temporary benefit in subjective evaluation only (65(More)
BACKGROUND The initial treatment of acute necrotizing pancreatitis is conservative. Intervention is indicated in patients with (suspected) infected necrotizing pancreatitis. In the Netherlands, the standard intervention is necrosectomy by laparotomy followed by continuous postoperative lavage (CPL). In recent years several minimally invasive strategies have(More)
