Randomized Controlled Trial Clinical TrialManagement of postoperative urinary retention: a randomized trial of in-out versus overnight catheterization.
There has been no consensus on the best catheterization strategy for the management of postoperative urinary retention. A prospective randomized trial was undertaken to establish the best practice guidelines for the management of postoperative urinary retention. The authors also evaluated the contemporary incidence of urinary retention following different categories of general surgery and examined risk factors associated with its occurrence. ⋯ Postoperative urinary retention should be managed by in-out catheterization. Indwelling catheterization for 24 h appeared to bestow no additional benefits. The incidence of urinary retention increases with age, anorectal procedures and the use of spinal anaesthesia.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of the effect of diclofenac with hyoscine-N-butylbromide in the symptomatic treatment of acute biliary colic.
Although non-steroidal anti-inflammatory drugs (NSAID) and spasmolytics have been used to relieve biliary colic, the role of these drugs in the natural history of biliary colic has not been clarified. The objective of the present study is to compare the efficacy of intramuscular diclofenac with intramuscular hyoscine in the treatment of pain of acute biliary colic, and to study their role in the natural history of biliary colic and in the prevention of cholelithiasis-related complications. ⋯ In patients with biliary colic, diclofenac gives much faster and more effective pain relief in a significantly larger number of patients as compared with hyoscine. Most remarkably, diclofenac can prevent progression of biliary colic to acute cholecystitis in a significant number of patients.

Randomized Controlled Trial Clinical TrialSurgical masks: operative field contamination following visor-to-visor contact.
Clashing of surgical visor masks frequently occurs when two surgeons bend over an operative field simultaneously; however, it is unknown whether this results in contamination. The purpose of the present study was to determine the potential for operative field contamination following surgical visor-mask clashes. The nature of bacterial contamination was also assessed. ⋯ Surgical visor mask clashes increase the risk of bacterial contamination of the operative field.

Randomized Controlled Trial Clinical TrialEarly oral feeding after colorectal resection: a randomized controlled study.
Nasogastric (NG) intubation is widely used following elective abdominal operations although it is associated with morbidity and discomfort. The present study is a randomised controlled trial on the effect of early oral feeding without NG decompression following elective colorectal resection for cancer. ⋯ Patients undergoing elective colorectal resection can be managed without postoperative NG catheters, starting oral feeding on the first postoperative day. Albeit, no reduction in postoperative hospital stay or patients' well being could be detected, abolition of postoperative NG intubation with early oral feeding was a safe approach, with only 20% of patients requiring NG decompression because of repeated episodes of vomiting.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialFluoropolymer coated Dacron or polytetrafluoroethylene for femoropopliteal bypass grafting: a multicentre trial.
This trial was designed to compare graft patency between expanded polytetrafluoroethylene (PTFE) and fluoro-polymer coated Dacron for femoropopliteal bypass in patients in whom saphenous vein was unavailable. ⋯ Polytetrafluoroethylene has superior primary patency and similar secondary patency to fluoropolymer coated Dacron. These results support the preferential use of PTFE in patients with critical limb ischaemia, especially when a below-knee distal anastomosis and smaller diameter graft is required.
