A Prospective Randomized Controlled Trial Comparing Extraperitoneal Stoma Creation Via the Arcuate Line Approach Versus Conventional Transperitoneal Stoma Formation for the Prevention of Parastomal Hernia

This study is a prospective, randomized controlled trial designed to compare two surgical techniques for stoma creation in patients undergoing colorectal surgery. The trial evaluates whether an extraperitoneal stoma created via the arcuate line approach can reduce the risk of developing parastomal hernia compared to the conventional transperitoneal stoma formation. Parastomal hernia is a common complication after stoma surgery, often requiring additional treatment or surgery. By testing a novel surgical route that avoids entering the abdominal cavity, this study aims to improve postoperative outcomes and quality of life for patients requiring a permanent stoma.

Perioperative and Postoperative Evaluation of Rectal and Urogenital Function in Patients Undergoing Rectal Resection

The aim of this study is the systematic analysis of the development of perioperative rectal and urogenital function in patients undergoing rectal resection with total mesorectal excision and the identification of risk factors for urogenital and sphincter function loss after this procedure. Knowledge of the corresponding risk factors could enable the identification of patient cohorts that could benefit from an intensified or altered postoperative treatment path. The results of this study could thus significantly influence the clinical management of patients with rectal cancer and improve the functional outcome in the long term.
