Effect on Incisional Hernia of Absorbable Barbed Suture for Midline Fascial Closure in Minimally Invasive Surgery for Colorectal and Gastric Cancers: A Prospective Randomized Trial

Interventions: Medical Device : All patients enrolled this trial will have midline incision for the extraction of resected specimen.
For the closure of midline incision, patients allocated in experimental group will receive continuous running suture using absorbable barbed suture material.
Patients allocated in control group will receive continuous running suture using absorbable nonbarbed suture material.
Primary outcome(s): incisional hernia incidence rate
Primary Purpose : Prevention, Intervention Model : Parallel, Blinding/Masking : Single, Blinding Target : Subject, Outcome Accessor, Allocation : RCT
