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 .
Methods for combining randomized clinical trials: strengths and limitations.
Methods for combining data from several studies exist and appear to be quite useful . None satisfactorily addresses the question of what studies should be combined . This issue is the most serious method ological limitation . Even studies with statistically significant interaction might still be combined if the effect were in the same direction . Thus , substantial scientific input is required as to what criteria must be met by each potential study . Much can be learned from combining or pooling data but it must be done cautiously . Pooling exercises do not replace well design ed prospect i ve clinical trials . Efforts for establishing basic design criteria to allow for multicentre and multicountry trials to be more easily combined might be useful .
