We found no significant differences between different types of drains .
Drains increase the harms to the patient without providing any additional benefit for patients undergoing open cholecystectomy and should be avoided in open cholecystectomy
BACKGROUND Cholecystectomy is the removal of gallbladder and is performed mainly for symptomatic gallstones .
Although laparoscopic cholecystectomy is currently preferred over open cholecystectomy for elective cholecystectomy , reports of r and omised clinical trials comparing the choice of cholecystectomy ( open or laparoscopic ) in acute cholecystitis are still being conducted .
Drainage in open cholecystectomy is a matter of considerable debate .
Surgeons use drains primarily to prevent subhepatic abscess or bile peritonitis from an undrained bile leak .
Critics of drain condemn drain use as it increases wound and chest infection .
OBJECTIVES To assess the benefits and harms of routine abdominal drainage in uncomplicated open cholecystectomy .
Literature searching for randomized controlled trials used in Cochrane reviews: rapid versus exhaustive searches.
OBJECTIVES To analyze sources search ed in Cochrane review s , to determine the proportion of trials included in review s that are indexed in major data bases , and to compare the quality of these trials with those from other sources . METHODS All new systematic review s in the Cochrane Library , Issue1 2001 , that were restricted to r and omized controlled trials ( RCTs ) or quasi- RCTs were selected . The sources search ed in the review s were recorded , and the trials included were checked to see whether they were indexed in four major data bases . Trials not indexed were checked to determine how they could be identified . The quality of trials found in major data bases was compared with those found from other sources . RESULTS The range in the number of data bases search ed per review ranged between one and twenty-seven . The proportion of the trials in the four data bases were Cochrane Controlled Trials Register = 78.5 % , MEDLINE = 68.8 % , Embase = 65.0 % , and Science/Social Sciences Citation Index = 60.7 % . Search ing another twenty-six data bases after Cochrane Controlled Trials Register ( CCTR ) , MEDLINE , and Embase only found 2.4 % additional trials . There was no significant difference between trials found in the CCTR , MEDLINE , and Embase compared with other trials , with respect to adequate allocation concealment or sample size . CONCLUSIONS There was a large variation between review s in the exhaustiveness of the literature search es . CCTR was the single best source of RCTs . Additional data base search ing retrieved only a small percentage of extra trials . Contacting authors and manufacturers to find unpublished trials appeared to be a more effective method of obtaining the additional better quality trials
