High tie versus low tie of the inferior mesenteric artery: a protocol for a systematic review

In anterior resection of rectum, the section level of inferior mesenteric artery is still subject of controversy between the advocates of high and low tie. The low tie is the division and ligation to the branching of the left colic artery and the high tie is the division and ligation at its origin at the aorta. We intend to assess current scientific evidence in literature and to establish the differences comparing technique, anatomy and physiology. The aim of this protocol is to achieve a meta-analysis that tests safety and feasibility of the two procedures with several types of outcome measures

Single-access laparoscopic left hemicolectomy

Single-incision surgery is an evolution of conventional laparoscopy. It reduces not only the invasiveness of the access but also the surgical procedure itself. Although SALS for colorectal resection was initially performed only for benign diseases, there is now an increasing adoption for malignancy, which raises questions concerning oncological adequacy. However, this approach is not yet used routinely for the treatment of benign and malignant colorectal disease, because clear advantages for the patient are still lacking. We report our standardized technique as well as the case series in the use of a single-access laparoscopic approach for the treatment of left colon disease
