Short Stitch Versus Traditional Suture for the Prevention of Incisional Hernia After Open Hepatectomy

Short Stitch Versus Traditional Suture for the Prevention of Incisional Hernia After Open Hepatectomy

Incisional Hernia Prevention After Open Hepatectomy by Small Tissue Bite Fascial Closure: A Randomized Clinical Trial

This clinical trial compares two different kinds of surgical closing techniques, short stitch suture or traditional suture, in patients who are having liver tumor surgery. This study may help researchers learn if one technique can lower the chances of developing a hole in the wall of the abdomen (an abdominal hernia) at the incision site better than the other.

PRIMARY OBJECTIVE: I. To assess whether small bites abdominal wall closure reduces the risk of developing incisional hernia following liver surgery. SECONDARY OBJECTIVES: I. To compare short-term perioperative outcomes between small bites and typical fascial closure technique. II. To assess the hernia incidence rate of short stich versus (vs.) standard closure in subgroups of patients with inverted-L or midline incisions. III. To assess the hernia incidence rate of Kawaguchi-Gayet hepatectomy complexity classifications I/II vs. III (hernia rate by extent of hepatectomy). IV. To assess the hernia incidence rate of preoperative chemotherapy or no preoperative chemotherapy (hernia rate by exposure to preoperative chemotherapy). V. To assess impact of small bites abdominal wall closure on health care quality of life following liver surgery. VI. To assess safety of small tissue bites fascial closure suture technique versus conventional fascial closure following hepatectomy. OUTLINE: Patients are randomized to 1 of 2 arms. ARM I (INTERVENTION): Patients undergo hepatectomy as planned using small bites fascial method for abdominal wall closure. ARM II (CONTROL): Patients undergo hepatectomy as planned using conventional fascial method for abdominal wall closure. After completion of study, patients are followed up at 1-4 weeks, and then at 3, 6, and 12 months.

Patients undergo hepatectomy as planned using conventional fascial method for abdominal wall closure.

Definition of incisional hernia will be based on the European Hernia Society: Any abdominal wall gap with or without a bulge in the area of a postoperative scar perceptible or palpable by clinical examination or imaging. Assessment of the primary outcome will occur at 3, 6, and 12 months with a computed tomography scan/magnetic resonance imaging. Scans will be read and assessed for incisional hernia by 3 independent assessors blinded to the allocation. A correlation coefficient will be determined for their assessments. The cumulative incidence rate of incisional hernia at 12 months will be estimated, along with the 95% confidence interval.

Post-operative infection, complication or pain will be assessed using Chi-squared test or Fisher's exact test.

Will use linear mixed effect modeling to assess the effects of time, arm as well as the interaction between arm and time.

Will be summarized using descriptive statistics (frequency, percentage) by arm, AE type, severity and attribution.
