Simple elective cholecystectomy: to drain or not

Abstract

We performed a large single-center prospective randomized controlled study to assess the role of peritoneal drainage in simple elective cholecystectomy. In 248 patients, drains were omitted; 122 patients had closed suction drains and 124 had Penrose drains. There were no deaths, and no patient required reoperation or drainage of a subhepatic collection. Wound infections occurred in eight patients with drains and in six patients without. Most infections were staphylococcal. Postoperative pulmonary complications and hospital stays were similar in patients with and without drains. Statistical analysis of the 10 available prospective controlled randomized studies (1,920 patients) by the method of odds ratios supported our findings. Simple elective cholecystectomy is safe without peritoneal drainage, but short-term drains do not increase morbidity.
