- Abstract
- Purpose: To determine if minimal dissection of the posterior wall of rectum can reduce rectal prolapse after laparoscopic assisted anorectal pull-through (LAARP) in male anorectal malformation (ARM) with rectourethral fistula. Methods: Eighty-six male patients with ARM who underwent LAARP in our center between 2007 and 2018 were retrospectively analyzed. There were 45 cases of prostatic urethral fistula, 24 bulbar urethral fistulas, and 15 bladder neck fistulas. Two patients had no fistula. To prevent rectal prolapses, we markedly short-ened the length of posterior rectal dissection from mid-2016. Dissection of posterior wall of rectum was performed minimally around the level of the fistula and the dissected portion of the posterior rectum was significantly shorter than the previous cases. For comparative analysis, patients were divided into two groups (before and after application of minimal dissection of posterior wall of rectum): Group A, from 2007 to mid-201 6 and Group B, from mid-2016 to 2018. Results: There were 60 patients in Group A and 26 patients in Group B. Demographic characteristics were not significantly different between the two groups. The median follow-up duration was 52.4 months for Group A and 26.9 months for Group B. Group B had lower incidence of rectal prolapse (11.5%) than Group A (68.3%) (p < 0.001). Upon our subgroup analysis based on types of fistula, patients with recto-prostatic urethral fistula and recto-bulbar urethral fistula showed significant reduction in the incidence of rectal prolapse (both p < 0.001). However, patients with recto-bladder neck fistula showed no statistical significance (p = 0.264). Conclusion: Minimal dissection of the posterior wall of rectum can reduce rectal prolapse in LAARP.
