Single-Incision Laparoscopic Versus Conventional Laparoscopic Surgery for Rectobladderneck and Rectoprostatic Anorectal Malformations.

Background

We compared the safety and feasibility of single-incision laparoscopic surgery (SILS) and conventional laparoscopic-assisted anorectoplasty (CLAARP). Materials and

Methods

We compared sacral ratio, age, operation time, blood loss, and length of hospital stay after the operation, and complications in 105 patients with rectobladderneck and rectourethral fistula who underwent operations from January 2010 to May 2014 in our institution (SILS, n = 51; CLAARP, n = 54). The Krickenbeck classification was used to evaluate the anorectal functions.

Results

The mean operative time in the SILS group (113.5 ± 12.7 minutes) was significantly shorter than that in the CLAARP group (126.2 ± 10.2 minutes) (P = .003). The intraoperative blood loss did not differ between groups (P = .75). There were no significant differences in the time needed to resume diet and length of hospital stay after the operation. The overall incidence rate of postoperative complications was similar (7.8% versus 7.4%, P = 1.00). There were no significant differences in voluntary bowel movement, soiling, and constipation between the two groups. No injuries to vessels, urethral or vas deferens occurred in either group. No mortality or morbidity of wound infection, rectal retraction, recurrent fistula, urethral diverticulum, or anal stenosis were encountered in our study.

Conclusions

SILS is a feasible and safe technique compared with CLAARP in terms of surgical outcomes.
