Abstract: ［Abstract］ Objective To investigate the application of an incision along skin line and subcutaneoustissue traction to underbelly surgery. Methods 262 cases of lower abdomen surgery were assigned to observation group including inguinal hernia repair，appendectomy，and hydrocele of hydrocele. This surgical procedure was performed through an incision along skin line and subcutaneous tissue and retraction in our hospital from July 2010 to December 2017. Another 278 patients who underwent conventional surgical incision were used as controls. Incision healing and adverse reactions were recorded and compared between the two groups. Results In patients of observation group，wound infection，wound hematoma，and local edema were less than that in the conventional incision group，and the average suture removal time was shortened，and the scar width was also reduced，and all P value were less than 0.05. Conclusion The transverse incision has a small scar and cosmetic incision. The subcutaneous tissue retraction through transverse incision can avoid damage to the vessels，thus reducing subcutaneous hematoma，wound infection and complications.
