Ultrasound findings following laparoscopic cholecystectomy

This study was set up to find the incidence of fluid collections in asymptomatic patients following laparoscopic cholecystectomy. Patients had an ultrasound scan on the first postoperative day and approximately 1 week later. Seven of 25 patients (28%) had a total of nine collections on the first postoperative day. Five had resolved by the follow-up scan and two patients developed new collections by the 1 week scan. None of the patients had significant postoperative symptoms. We emphasize the high incidence of ultrasonically detectable fluid collections in asymptomatic patients following laparoscopic cholecystectomy, encourage caution in attributing postoperative morbidity to such findings, and suggest that repeat scanning may be helpful in patient management.
