Core tip: Laparoscopic cholecystectomy is the procedure of choice for patients with symptomatic gallstones. Although some patients will need overnight observation many of the younger patients, with low body mass index (BMI), that did not have severe gallbladder infection may be performed under day surgery, in institutions that have the necessary setup. The current study show that postoperative blood analyses does not predict nor correlate with postoperative complications and has no impact on outcome. The only independent predictors of complications on multivariate analysis are BMI and drain placement that was used a surrogate for technical difficulty during surgery. Intuitively length of surgery is thought to be in correlation with technical difficulty. In centers were supervised residents perform high percentage of the operations, length of surgery does not correlate with difficulty or post operative complications and by itself does not seem to indicate need for postoperative blood analyses.
