Zheng’s anchor suturing technique for safe and cosmetic umbilical incision in transumbilical laparoendoscopic single-site surgeries

Transumbilical laparoendoscopic single-site surgery (TU-LESS) is a new and evolving surgical method suitable for gynecological diseases, because of its minimal invasion and good cosmetic results. However, since the incision required for this procedure is longer than that for traditional laparoscopy, it may be associated with a higher incidence of postoperative incision complications, such as umbilical hernia, infection, hematoma, and poor wound healing. Moreover, the patient may be left with a misshapen umbilicus because intensive surgery is performed through a single umbilical incision. To minimize the incisional complications and meet patients’ cosmetic expectations, we designed a novel suturing technique, named “Zheng’s anchor suture technique”. This video demonstrates the specific steps and shows photographs of patients’ umbilici that were sutured by this technique, taken after recovery from various operations.
