Endo GIA stapler malfunction in a small bowel loop resection

Abstract

Endovascular gastrointestinal anastomosis (Endo-GIA) staplers are widely used in various surgical procedures despite difficulties in operating them and associated mechanical failures. We present a case of a patient whose post-operative recovery was complicated by intraoperative Endo-GIA stapler failure, which is rarely reported in literature. Our report describes the behavior and consequences of surgical stapler failure so surgeons can anticipate challenges of newer surgical devices while maintaining optimal patient outcomes.

Endovascular treatment of traumatic penile arteriospongious fistula in a patient with erectile dysfunction: a case report and literature review

“…Contrast-enhanced CT angiography represents the imaging modality of choice when the arteriovenous fistula is related to pelvic trauma. CT angiography shows early filling of a vein adjacent to a contrast opacified artery, indicating a connection between the two vessels [ 3 , 6 ]. CT angiography or magnetic resonance angiography provides detailed anatomical features of involved vessels and the site and size of arteriovenous fistula and accordingly guides the decision on the best treatment option [ 6 ].…”

“…Treatment of traumatic arteriovenous fistula consists of endovascular embolization, surgical ligation, or a combination of both techniques [ 3 ]. The main goal of all treatment options is to isolate and close the site of arteriovenous communication.…”

“…The choice of embolic material depends on the type and size of arteriovenous communication, the flow velocity, and whether the involved vessels can be occluded or require preservation. The most common embolization agent is coil since it allows precise and safe occlusion of arteriovenous fistula [ 3 ]. Alternatively, in some cases, embolization can also be performed with gel-foam, polyvinylalcohol (PVA), autologous blood clot, or liquid agents, such as N-butyl cyanoacrylate glue or Onyx [ 6 – 8 ].…”

“…An arteriovenous fistula is an abnormal communication between an artery and a vein. The anomalous passageway creates a low-resistance and high-flow system in which the blood flows directly from an artery into a vein, bypassing capillaries and therefore diminishing tissue perfusion [ 3 ]. Post-traumatic penile arteriovenous fistula manifests as high-flow priapism due to the formation of an arteriocavernosal fistula.…”
