Surgical management of urachal remnants in children: open versus laparoscopic approach: A STROBE-compliant retrospective study

Urachal remnants (UR) represent a failure in the obliteration of the allantois, which connects the bladder to the umbilicus, at birth. Surgical management of UR in children is controversial. The traditional surgical approach involves a semicircular intraumbilical incision or a lower midline laparotomy. Recently, many reports have supported the laparoscopic approach (LA) for removing UR. However, there is a paucity of data comparing the benefits of LA those of the open approach (OA). We retrospectively reviewed all children (aged ≤16 years) with UR who underwent surgical procedures. Age at surgery, sex, operative time, intraoperative or postoperative complications, total wound length, and length of hospital stay length after operation were analyzed. Overall, 30 children aged between 9 months and 16 years (mean 9.0 years) underwent surgical procedures: 15 were treated by OA and 15 were treated by LA. The only statistically significant variable was the operative time. Furthermore, we reanalyzed the age distributions of the older children (aged ≥10 years). In this group, no significant difference in the operative time between OA and LA was observed; however, there was a statistically significant difference in the total wound length. Our review indicated that LA required longer operative time than OA without any cosmetic advantage. However, in older children (aged ≥10 years), the difference in the operative time was not significant; moreover, LA provided greater cosmetic advantage. LA is recommended for older children (aged ≥10 years) because of its cosmetic advantage.
