A Novel Method of Treating Rectal Diverticulum Using Transanal Minimally Invasive Surgery (TAMIS)

Abstract

Rectal diverticula are extremely rare with an incidence of less than 0.1% of colonic diverticular disease cases, and the factors that contribute to their evolution are poorly understood. Majority of the cases are diagnosed incidentally, and they are usually clinically asymptomatic and carry a low risk of developing complications; therefore, treatment is not required in most cases. Surgery is generally performed only in the event of complications or when they become symptomatic, such as with the development of obstructive defecation with an impacted fecalith within the diverticulum. As it is a rare entity, there is currently no consensus on the surgical management of rectal diverticulum. Here, we describe a novel and effective method of surgical management of rectal diverticulum utilizing transanal minimally invasive surgery.
