Over‐the‐scope clip for acute esophageal variceal bleeding

Over‐the‐scope clip (OTSC) has been reported to control non‐variceal bleeding; however, the use of this device for acute variceal hemorrhage (AVH) is very limited. We report our experience regarding the use of OTSC in patients with AVH in terms of technical success and safety. A retrospective clinical experience case series study was conducted from October 2017 to June 2019 at two tertiary care centers. Adult patients with AVH as a result of small varices managed with OTSC after endoscopic band ligation (EBL) failure were enrolled. Standard gastroscope and OTSC ‘type a’ with a cap of 11 mm in diameter were used in all procedures. Total of five patients with chronic liver disease (Child‐Pugh score ≤8) and portal hypertension (hepatic venous pressure gradient, mean 14.4 ± 1.3 mmHg) were included. Four of them presented collapse of the bleeding varix, and one had wall disruption associated with fibrosis secondary to prior banding. We were able to stop AVH in all patients without clip‐related adverse events during a 30‐day follow‐up period. Two patients developed solid food dysphagia after 3 months of clip deployment that resolved after removal using a bipolar cutting device. Twin grasper or anchor were not used to aid or facilitate the approximation of opposite edges in any patient. No additional local therapies or new endoscopic session for variceal eradication were required. This case series shows preliminary success controlling AVH with OTSC after EBL failure in patients with small varices. Esophageal dysphagia may appear as a complication during follow up but it can be resolved by clip removal.
