Staple-line erosion: A common source of recurrent bleeding following stapled oesophageal transection

Abstract

Abstract Recurrent bleeding after stapled oesophageal transection was studied in 73 patients with cirrhosis transected for acute variceal bleeding. The most frequent source of bleeding was partial or total circumferential oesophageal erosion at the transection: staple-line erosion. This lesion occurred in 36 (49 per cent) patients and was the source of rebleeding in 29 (40 per cent) patients with 54 episodes. Rebleeding in 22 (30 per cent) patients was due to varices in nine (12 per cent), peptic ulcer in six (8 per cent), gastric erosions in two (3 per cent) and unknown sources in five (7 per cent), accounting for 33 episodes. The mean(s.e.m.) blood transfusion requirement for bleeding from staple-line erosions was 1.5(0.25) units per bleed versus other sources, 6.5(1.0) units per bleed (P < 0.001). Staple-line erosion was present at the first postoperative endoscopy in 11 (15 per cent) patients but the time to appearance varied widely. The lesion was more common in patients with Pugh's grade A liver disease at the time of transection, reflecting the increased survival rate of these patients. Staple-line erosion is a common source of minor recurrent bleeding following stapled oesophageal transection.
