Current evidence on powered versus manual circular staplers in colorectal surgery: a systematic review and meta-analysis.

Purpose: This meta-analysis aims to evaluate the efficacy of powered circular staplers (PCS) compared to manual circular staplers (MCS) in reducing anastomotic leakage (AL) and postoperative bleeding (AB) in colorectal surgery.

Methods: Extensive searches were performed in the Embase, PubMed, and SCOPUS electronic bibliographic databases. Most studies were of an observational nature, and only one randomized clinical trial was identified.

Incidence of anastomotic leakage using powered circular staplers versus manual circular staplers for left colorectal anastomosis: a cost-effectiveness analysis.

Background: Colorectal anastomotic leakage causes severe consequences for patients and healthcare system as it will lead to increased consumption of hospital resources and costs. Technological improvements in anastomotic devices could reduce the incidence of leakage and its economic impact. The aim of the present study was to assess if the use of a new powered circular stapler is cost-effective.
