Routine peritoneal drainage of the surgical bed after elective distal pancreatectomy: is it necessary?

Recent literature suggests that peritoneal drainage (PD) is not helpful after elective pancreatectomy and may be detrimental. Data specific to distal pancreatectomy (DP) have not received prior evaluation.

We performed a retrospective review of patients who underwent DP. Factors examined included postoperative morbidity and the need for therapeutic intervention.

Sixty-nine patients had DP, 30 without PD. Thirty-four patients suffered 45 complications, most were intra-abdominal in nature. Twelve, 19, and 3 patients required radiologic drainage, reoperation, or both, respectively. There was no difference between groups relative to intra-abdominal complications or the need for therapeutic intervention. Of 39 patients undergoing PD, 19 had abdominal morbidity. The drain was useful in identifying and/or treating the complication in 3 patients.

First, PD after DP does not confer a reduction in morbidity or the need for therapeutic intervention versus patients with no drains. Second, the presence of a drain infrequently was helpful in detecting complications. Third, a multi-institutional, randomized study is recommended.
