Abstract
A study of risk factors for wound infection among patients undergoing elective cholecystectomy was undertaken. Over a 2-Year period 177 patients who underwent elective cholecystectomy for symptomatic gall stone disease were randomized into groups, one receiving antibiotics (96 patients) and the other not receiving antibiotics (81 patients). Gall bladder bile and wound swab were cultured to detect bacterial growth. Duration of preoperative hospital stay, type of skin incision and operating time were noted for each patient. Postoperatively wound infection developed in 22/177 (12%) patients. The infection rate was lower in the antibiotic group 3/96 (3%) as compared to the non-antibiotic group 19/81 (23.5%). Wound sepsis occurred in 11/37 (23%) of patients with bactibilia as compared to 11/140 (7.8%) patients with sterile bile. Stepwise logistic regression analysis showed that bactibilia and use of prophylactic antibiotics were the most significant predictors of wound infection in low risk patients undergoing elective cholecystectomy.
