Optimum mesh and port sizes for laparoscopic incisional hernia repair.

Purpose: Since incisional hernia repair was introduced into laparoscopic surgical practice it has been recognized that larger meshes can be problematic to successfully insert through laparoscopic ports. This study aims to facilitate the choice of mesh and port by documenting the minimum port sizes realistically needed for insertion of different types and sizes of onlay mesh. It also aims to evaluate the optimal insertion techniques.

Transanal endoscopic microsurgery: where are we now?

Aims: This review of literature aimed to assess the role and establish the current status of transanal endoscopic microsurgery (TEM) in the management of benign and malignant rectal lesions.

Methods: A review of the literature was undertaken through the Medline database and by cross-referencing previous publications, thus identifying 54 relevant publications on TEM in the management of rectal lesions. Aggregated results of various parameters were calculated but statistical comparisons deemed unsuitable due to heterogeneity of data.

Local excision of rectal cancer: review of literature.

In selected patients, local excision of rectal cancer may be an alternative to radical surgery such as abdominoperineal excision of the rectum or anterior resection. Local excision carries lower mortality and morbidity, without the functional disturbance or alteration in body image that can be associated with radical surgery. There are several techniques of local therapy for rectal cancer, with most experience being available in transanal excision.
