title: Influence of intraperitoneal drainage after cholecystectomy; a prospective ultrasonographic study.
abstract: One hundred and fifty patients were prospectively randomised into 3 groups (50 in each group); to receive a passive drain, closed suction drain or no drain after elective cholecystectomy. The drain was removed within 24 hours in 84% of patients and was continued longer only if the amount of drainage was excessive or bilious. On the 3rd post-operative day, an ultrasound examination was performed in all patients for detection of subhepatic/subphrenic collection. Collections were more frequently encountered in the patients without any drain (42%) followed by passive drain (26%) and suction drain group (20%). Chest complications were frequently noted (passive drain; 6% suction drain, 12%, and no drain, 8%), however, occurrence of this complication in various groups was similar (p > 0.1). Two patients (4%) without drain required ultrasound guided aspiration of subhepatic collection. Mean post-operative hospital stay was nearly equal for all the groups (passive drain: 4.22 +/- 1 days, suction drain: 4.26 +/- 1.4 days and no drain: 4.62 +/- 2.3 days). Drainage reduced the incidence of post-cholecystectomy collections and need for invasive intervention for collection related complications. However, the type of drainage (active or passive) did not influence the incidence of collection, frequency of complications and duration of post-operative hospital stay.
