Parastomal hernia formation is common following formation of an abdominal stoma, with the risk of subsequent incarceration, obstruction and strangulation. Current treatment options include non-operative management, stoma relocation and fascial repair with or without mesh. The purpose of this systematic review was to evaluate the effectiveness and safety of open mesh repair of a parastomal hernia and to compare open non-mesh fascial repair with mesh techniques of parastomal hernia repair. ⋯ Morbidity and mortality did not differ significantly between the techniques used to repair a parastomal hernia. This study shows that mesh repair of a parastomal hernia is safe and significantly reduces the rate of recurrence compared with sutured repair, which should only be used in exceptional circumstances. There is insufficient evidence to determine which mesh technique (onlay, sublay or underlay) is most successful in terms of recurrence rates and morbidity.

Transanal TME is a new approach to performing minimally invasive rectal resection. It is particularly well suited for patients with locally advanced distal rectal cancer and obesity, where the abdominal approach is challenging. Transanal TME can be performed with either TAMIS or TEM. Here, we report our initial experience with transanal TME using TAMIS (TAMIS-TME). ⋯ Transanal TME is a feasible method for oncologic resection of locally advanced mid- and distal-rectal cancer with curative intent. It has special application for patients with obesity and anatomic constraints such as a narrow male pelvis.
