Predisposing Factors and Management of Postoperative Bleeding After Radical Gastrectomy for Gastric Carcinoma
Overview

Purpose: To promote proper management of postoperative bleeding, we investigated the clinical manifestations, predisposing factors, diagnostic approaches, and treatments of bleeding complications after gastric cancer surgery.
Methods: Using a prospectively constructed database, we reviewed retrospectively 39 patients who suffered bleeding complications from among a total 1027 patients who underwent surgery for gastric cancer between 2004 and 2008.
Results: Operating time (hazard ratio [HR] 1.842, 95% confidence interval [CI] 1.524-2.367) and body mass index (HR 1.454, 95% CI 1.128-1.792) were significant predisposing factors for postoperative bleeding after gastric cancer surgery. Luminal bleeding occurred in 16 patients: as simple anastomosis site bleeding, treated successfully with conservative or endoscopic treatment, in 13; and as pseudoaneurysmal bleeding in 3, treated successfully with surgery in 2, but resulting in the death of 1. Abdominal bleeding occurred in 23 patients, requiring surgery in 9 and arterial embolization in 1. The most common finding at reoperation was bleeding from the mesocolon surface. The mean hospital stay of patients with postoperative bleeding was 21 (± 20) days.
Conclusions: Postoperative bleeding can be managed successfully with a tailored approach, considering its origins and clinical manifestations. Arterial pseudoaneurysms are a rare cause of luminal bleeding, but they can be fatal and should be suspected when extensive luminal bleeding presents after gastric cancer surgery.
