With an incidence ranging between 0.3 % and 2.4 %, buried bumper syndrome (BBS) is a relatively rare complication after percutaneous endoscopic gastrostomy (PEG) in which the internal fixation device of the cannula – the retention bumper – migrates partially (incomplete BBS) or completely (complete BBS) into the gastric wall with subsequent mucosal overgrowth [1] [2]. Management of complete BBS can be challenging, and a variety of endoscopic devices have been described for endoscopic treatment, including needle-knives, wire-guided papillotomes, the sphincterotome-like Flamingo device, or a combination of different techniques [3] [4] [5].

The Clutch Cutter is a forceps-type resection device with a serrated cutting edge that allows simultaneous grasping and cutting or coagulating of tissue. The outer edge of the Clutch Cutter is insulated; electrosurgical current energy is concentrated at the closed blade to avoid unintentional incision. We present the first case of endoscopic removal of a complete BBS with the Clutch Cutter.

A 77-year-old man with a known radiation-induced esophageal stricture requiring intermittent enteral feeding through a PEG presented with obstruction of his PEG tube. Esophagogastroduodenoscopy showed a 4-cm area of granulomatous – fibrotic tissue with a central retraction in the anterior wall of the gastric antrum, thereby confirming complete BBS ([Fig. 1 a]). A .035-inch Jagwire was inserted through the gastrostomy to identify the center of the retention bumper and was used as a guide for subsequent incisions. Next, granulomatous tissue was grasped with the opened Clutch Cutter and, with tissue inside the forceps, the Clutch Cutter was gently pulled back in order to avoid cutting too deep ([Video 1]). During pull-back, electrocautery was applied using an Erbe Vio 200 D-system with the following settings: forced coagulation 30 W, Endo Cut Q with effect 1, duration 3, interval 1. The granulomatous tissue overgrowing the buried bumper was radially incised at two sites on opposite sides of the Jagwire, leading to the creation of a slit-like mucosal pocket ([Fig. 1 b, c]). The PEG tube was then mobilized and gently pushed towards the gastric lumen from externally, leading to release of the buried bumper and the PEG tube remnant from the overgrown tissue into the gastric lumen ([Fig. 1 d]; [Video 1]). Total procedure time from insertion to withdrawal of the endoscope was 11 minutes, and the whole procedure was performed with the patient under conscious sedation with midazolam and with broad-spectrum antibiotic prophylaxis.

Quality:

In conclusion, our case illustrates the potential of the Clutch Cutter for rapid and safe endoscopic treatment of BBS.
