Abstract

Multiple reports have documented unsuspected inguinal hernias which result in difficulties during the colonoscopic examinations of patients. In most cases, the colonoscopy can be delayed until a surgical consult has further evaluated the inguinal hernia. This case report documents a patient who required a colonoscopy but surgical intervention for the detected inguinal hernia was not appropriate due to his co-morbid medical conditions. With the use of the combination of an enteroscope fitted with a cap and fluoroscopy, the inguinal hernia was able to be negotiated and the diagnosis of a cecal carcinoma was able to be confirmed.

Keywords: Inguinal hernia, Cap-assisted colonoscopy, Cecal carcinoma, Fluoroscopy, Enteroscope

Core tip: Patients with inguinal hernias who are unfit for surgical repair but who have otherwise strong indications for colonoscopy are at risk of failed colonoscopy or an incarcerated colonoscope. This case study demonstrates that the use of a cap fitted to a more flexible enteroscope with fluoroscopic guidance can aid in the negotiation of the scope past the loops of bowel in the hernia sac.
