Three Sutures With Different Absorption Rates for Lower Abdominal Incision

Summary

The previous studies have demonstrated that wedge excision combined modified buried vertical mattress suture (WE-MBVMS) provides better aesthetic outcomes than traditional ways. Prolonged tension reduction is crucial in WE-MBVMS suppressing scar, while suture used during WE-MBVMS decided the length of tension reducing time to a certain degree. However, presently surgeons select suture for WE-MBVMS mostly according to their personal preference and clinical experience and clinical comparative evidence exposing the best suture for desired cosmetic outcome is lacking. Here, investigators purposed to establish a feasibility trial comparing the scars left by WE-MBVMS using sutures with different tension holding time.

This is a feasibility, single-center RCT with 35 patients aiming to compare the scar of the hypogastric incision sutured by three different-absorption-rate sutures with WE-MBVMS. The incision induced by donating skin grafts is evenly divided into three segments, each segment randomly uses one of three different sutures randomly allocated by the SAS (V.9.4) statistical software. The feasibility of this study will be assessed by the primary outcomes, including patient and clinician enrolment refusal as well as their reasons, reasons for ineligibility, recruitment ratio, retention and withdrawal at each follow-up point (1, 3, and 6 months), reasons for withdrawal, integrity of collected data and adverse event rates. Secondary outcome measures of the cosmetic outcome of scar will help shape future fully powered RCT by formulating the sample size.

Interventions

DEVICE

WE-MBVMS using suture Vicryl (Polyglactin 910; Johnson & Johnson International, USA);

The skin around the incision is dissociated from the bottom, followed by measuring the length of the wound and dividing it into three segments evenly. Each segment randomly received 2-0 Vicryl suture, 2-0 PDS suture, or 2-0 Ethibond suture to sew up the incision with WE-MBVMS.

DEVICE

WE-MBVMS using suture PDS (polydioxanone; Johnson & Johnson International, USA)

The skin around the incision is dissociated from the bottom, followed by measuring the length of the wound and dividing it into three segments evenly. Each segment randomly received 2-0 Vicryl suture, 2-0 PDS suture, or 2-0 Ethibond suture to sew up the incision with WE-MBVMS.

DEVICE

WE-MBVMS using suture Ethibond (polyester; Johnson & Johnson International, USA）

The skin around the incision is dissociated from the bottom, followed by measuring the length of the wound and dividing it into three segments evenly. Each segment randomly received 2-0 Vicryl suture, 2-0 PDS suture, or 2-0 Ethibond suture to sew up the incision with WE-MBVMS.
