Clinical features of postoperative anastomotic bleeding after gastrectomy and efficacy of endoscopic hemostasis: a case–control study

Postoperative anastomotic bleeding (PAB) is relatively rare; however, it can be lethal if not treated immediately. The aim of our study was to investigate the clinical features of PAB and the efficacy of endoscopic hemostasis (EH) for PAB.
Between January 2004 and May 2013, 16,591 patients underwent gastrectomy for gastric cancer at Asan Medical Center. Among them, 36 patients who experienced PAB within 2 months after the gastrectomy were enrolled as a case group. Each subject was matched at a ratio of 1:5 with randomly selected patients without bleeding during the same period (n = 180, control group). The clinical outcomes and risk factors for patients with PAB were compared with those of the control group, and the results of EH were evaluated retrospectively.
The incidence of PAB was 0.22% (n = 36), and the median duration from gastrectomy to PAB was 34.5 h (interquartile range, 12.3–132.8 h). EH was attempted in 25 patients (69.4%); surgery was performed in 6 patients (16.7%); and conservative management was applied in 5 patients (13.9%). PAB-related death occurred in three patients (8.3%; one in each treatment modality). Among 25 patients with primary EH, 16 were treated successfully (64%) and hemoclip was the most commonly used endoscopic tool (52%). In the multivariate analysis, the type of gastrectomy was found to be a risk factor for PAB (odds ratio 3.448, 95% confidence interval, 1.138–10.448, p = .029).
Although PAB is an infrequent and potentially life-threatening complication, endoscopy can be considered as a useful method to avoid additional surgery in properly selected patients.
