- Background: Several randomized clinical trials have compared laparoscopic cholecystectomy (LC) and small-incision open cholecystectomy (SIOC). Most have had wide exclusion criteria and none was expertise-based. The aim of this expertise-based randomized trial was to compare healthcare costs, quality of life (QoL), pain and clinical outcomes after LC and SIOC. Methods: Patients scheduled for cholecystectomy were randomized to treatment by one of two teams of surgeons with a preference for either LC or SIOC. Each team performed their specific method (SIOC or LC) as a first-choice operation, but converted to open cholecystectomy and common bile duct exploration when necessary. Intraoperative cholangiography was carried out routinely. The intention was to include all patients undergoing cholecystectomy, including emergency operations and procedures involving surgical training for residents. Results: Some 74.9 per cent of all patients undergoing cholecystectomy were included. Of 355 patients randomized, 333 were analysed. Self-estimated QoL scores in 258 patients, analysed by the area under the curve method, were significantly lower in the SIOC group at 1 month after surgery: median 2326 (95 per cent confidence interval 2187 to 2391) compared with 2411 (2334 to 2502) for the LC group (P = 0.030). The mean(s.d.) duration of operation was shorter for SIOC: 97(41) versus 120(48) min (P < 0.001). There were no significant differences between the groups in conversion rate, pain, complications, length of hospital stay or readmissions. Conclusion: SIOC had comparable surgical results but slightly worse short-term QoL compared with LC. Registration number: NCT00370344 (http://www.clinicaltrials.gov).

- BACKGROUND: Four liters or more of orally taken polyethylene glycol solution (PEG) has proved to be an effective large-bowel cleansing method prior to colonoscopy. The problem has been the large volume of fluid and its taste, which is unacceptable to some examinees. We aimed to investigate the effectiveness of 2 l PEG combined with senna compared with 4 l PEG for bowel preparation. METHODS: The design was a single-center, prospective, randomized, investigator-blinded study with parallel assignment, in the setting of the Endoscopy Unit of Umeå University Hospital. Outpatients (n = 490) scheduled for colonoscopy were enrolled. The standard-volume arm received 4 l PEG, and the low-volume arm received 36 mg senna glycosides in tablets and 2 l PEG. The cleansing result (primary endpoint) was assessed by the endoscopist using the Ottawa score. The patients rated the subjective grade of ease of taking the bowel preparation. Analysis was on an intention-to-treat basis. RESULTS: There were significantly more cases with poor or inadequate bowel cleansing after the low-volume alternative with senna and 2 l PEG (22/203) compared with after 4 l PEG (8/196, p = 0.027). The low-volume alternative was better tolerated by the examinees: 119/231 rated the treatment as easy to take compared with 88/238 in the 4 l PEG arm (p = 0.001). CONCLUSIONS: 4 l PEG treatment is better than 36 mg senna and 2 l PEG as routine colonic cleansing before colonoscopy because of fewer failures.

- Objective. Since early 1970s, prospective randomized controlled trials have emphasized the advantages of early cholecystectomy in patients with acute cholecystitis, compared to elective delayed cholecystectomy. The aim of this investigation was to study surgery for acute gallbladder disease in Sweden during a 15-year period when open cholecystectomy was replaced by a laparoscopic procedure. Material and methods. Data from the Swedish National Patient Register and the Cause of Death Register 1988-2006 comprising hospital stays with a primary diagnosis of gallbladder/gallstone disease in Sweden were retrieved. Patients were analyzed with reference to timing of cholecystectomy, length of hospital stay, and mortality. Results. Emergency cholecystectomy at index (first) admission or at readmission within 2 years of index admission was performed in 32.2% and 6.1% of patients, respectively. Elective cholecystectomy within 2 years of index admission was performed in 20.3% patients, whereas 41.3% of all patients did not undergo cholecystectomy within 2 years. Standardized mortality ratio did not significantly change during the audit period. Total hospital stay (days at index stay and subsequent stay(s) for biliary diagnoses within 2 years) was shorter for patients who had emergency cholecystectomy at first admission compared to patients with later or no cholecystectomy within 2 years. Conclusions. Around 30% of patients with acute gallbladder disease were operated with cholecystectomy during the first admission with no time trend from 1990 through 2004. A total of 40% of patients with acute gallbladder disease were not cholecystectomized within 2 years. Analysis of outcome of long-term conservative treatment is warranted.

- BACKGROUND: The preferred strategies for treatment of common bile duct stones have changed from choledochotomy with cholecystectomy to sphincterotomy with or without cholecystectomy. The aim of the present study was to compare the effectiveness of these treatment strategies on a nationwide level in Sweden. METHODS: All patients with hospital care for benign biliary diagnoses 1988-2006 were identified in Swedish registers. Patients with common bile duct stones and a first admission with choledochotomy and or endoscopic sphincterotomy from 1989 through 2006 comprised the study group. These patients were analyzed with respect to readmission for biliary diagnoses and acute pancreatitis. RESULTS: Incidence of open and laparoscopic choledochotomy decreased from 19.4 to 5.2, whereas endoscopic sphincterotomy increased from 5.1 to 26.1 per 100,000 inhabitants per year, respectively. Among patients treated for common bile duct stones (n = 26,815), 60.0 % underwent cholecystectomy during the first hospital admission in 1989-1994, compared to 30.1 % in 2001-2006. The treatment strategy that included endoscopic sphincterotomy was associated with more readmissions for biliary diagnoses and increased risk for acute pancreatitis than the treatment strategy with choledochotomy. However, patients treated with endoscopic sphincterotomy and concurrent cholecystectomy at the index admission had the lowest risk of readmission. CONCLUSIONS: Cholecystectomy has been increasingly separated from treatment of bile duct stones, and endoscopic sphincterotomy has superseded choledochotomy as a first alternative for bile duct clearance in Sweden. In patients fit for surgery, clearance of the common bile duct can be combined with cholecystectomy, as it probably reduces the need for biliary related readmissions.
