Introduction: The Over-The-Scope Clip (OTSC®) system (Ovesco) and Padlock Clip® (PC) Defect Closure System (Steris) are endoscopic tools developed to manage severe gastrointestinal hemorrhage, perforation, and surgical leaks. The removal of either system is very difficult if not impossible. Here we report a case of failed PC hemostasis salvaged by OTSC.

Case Description/Methods: A 33-year-old male with alcoholic cirrhosis presented to the ED after a syncopal episode and melena. He was hypotensive, tachycardic and his labs showed a hemoglobin of 6.9, lactic acid of 3.8, creatinine of 1.98, and bilirubin of 16. He was admitted to the MICU for hemorrhagic shock. The patient reported recent admission to another hospital where multiple EGD were performed. Our EGD showed active bleed from two large duodenal bulb ulcers where a PC and a standard endoclip, previously placed at the outside hospital, were seen in position. We decided to treat these ulcers using OTSCs after the endoclip was removed; the PC was left in place as removal was impossible for this type of device and the OTSC was placed directly over the PC. Complete hemostasis of both ulcers was achieved. As the patient became hemodynamically unstable again, a second look EGD was performed two days later, The OTSC clips were in good positions and no signs of bleed were noted. The patient however continued to deteriorate and eventually died despite stable hemoglobin level without overt signs of GI bleed.

Discussion: In the only randomized control trial comparing OTSC with PC, an ex vivo model experiment demonstrated that OTSC consistently halted spurting bleeding but not PC. Both systems utilize a design similar to that for endoscopic band ligation. Steris recommends treating lesions no greater than 2 cm using PC while no official size limit was recommended by Ovesco for OTSC. OTSC could be removed using a specialized cutter but PC cannot be removed once placed. Here we report the first case where failed hemostasis using PC was salvaged by OTSC while the PC device was left in place.
