Three-flap umbilicoplasty: a novel and preliminary method of laparoendoscopic single-site transumbilical surgical approach for urachal remnants.

PURPOSE: Symptomatic urachal remnants are rare benign anomalies affecting young adults. For these patients, both curative treatment and acceptable postoperative aesthetic outcomes are important. Here, we describe a novel transumbilical approach, using Y-shaped incisions and three-flap umbilicoplasty techniques, to improve repair and aesthetic outcomes.

MATERIALS AND

METHODS

The clinical and perioperative data of 16 patients (11 men; median age, 25 years; range 16-46 years) who underwent LESS surgery and three-flap umbilicoplasty (LESS group) between December 2013 and March 2017 were analyzed. For comparison, the perioperative data of those who underwent conventional laparoscopic surgery (CL group) between May 2010 and November 2013 at the same institutions were investigated.

RESULTS

The median operative time of the LESS group was longer than that of the CL group (146.5 vs 107 min; p = 0.009). The estimated blood loss and postoperative hospital stay were not significantly different between the two groups. The two perioperative complications were injury to the transverse colon serosa and minor surgical site infection. Both complications were resolved with appropriate management.

CONCLUSIONS

This novel umbilical approach is useful for patients with symptomatic urachal remnants, with the reduction in port-site scarring resulting in good postoperative cosmesis.
