Comparison between umbilical and transverse right upper abdominal incision for pyloromyotomy

J Pediatr Surg. 2004 Jul;39(7):1091-3. doi: 10.1016/j.jpedsurg.2004.03.063.


Background: Besides laparoscopic pyloromyotomy, the operation for pyloric stenosis has been performed using 2 standard open surgical exposures: the right upper quadrant (RUQ) incision and the semi-circumumbilical (UMB) incision. The aim of this study was to compare the morbidity and cosmetic results of both open exposures.

Methods: Between 1990 and 1995, we performed 104 pyloromyotomies through a RUQ incision. These operations were retrospectively compared with 133 UMB incisions performed between 1995 and 1999.

Results: There were no significant differences between the 2 groups regarding age at presentation, sex, and preoperative status. Only a significantly higher percentage of patients with a metabolic alkalosis before surgery was found in the UMB group, but this did not affect morbidity rate. The groups did not differ significantly with respect to mucosal perforations (P =.95), wound infections (P =.53), inadequate pyloromyotomies (P =.42), or other complications. The mean operating time was slightly longer in the UMB group (P <.025). The UMB approach produced a better cosmetic result, with an almost invisible scar.

Conclusions: This study has shown that the UMB approach has equal intra- and postoperative complication rates as compared with the RUQ approach. The main advantage of the UMB approach is that it produces an excellent long-term cosmetic result.
