Drain After Laparoscopic Cholecystectomy for Acute Calculous Cholecystitis. A Pilot Randomized Study

Drainage after laparoscopic cholecystectomy (LC) for acute calculous cholecystitis (ACC) is used without evidence of its efficacy. The present pilot study was designed to address this issue. After laparoscopic gallbladder removal, 15 patients were randomized to have a drain positioned in the subhepatic space (group A) and 15 patients to have a sham drain (group B). The primary outcome measure was the presence of subhepatic fluid collection at abdominal ultrasonography, performed 24 h after surgery. Secondary outcome measures included postoperative abdominal and shoulder tip pain, use of analgesics, and morbidity. Abdominal ultrasonography did not show any subhepatic fluid collection in eight patients (53.3 %) in group A and in five patients (33.3 %) in group B (P?=?0.462). If present, median (range) subhepatic collection was 50 mL (20–100 mL) in group A and 80 mL (30–120 mL) in group B (P?=?0.573). No significant differences in the severity of abdominal and shoulder pain and use of parenteral ketorolac were found in either group. Two biliary leaks and one subhepatic fluid collection occurred postoperatively. The present study was unable to prove that the drain was useful in LC for ACC, performed in a selected group of patients.
