Author contributions: Cosma S contributed to study conception, design, data acquisition, analysis, interpretation, and writing of article; Benedetto C contributed to editing, reviewing and final approval of article; Petruzzelli P and Danese S performed surgery.
Institutional review board statement: This retrospective study was performed without direct contact with patients and no individual patient information was revealed. The described experimental procedure (nerve preserving laparoscopic sacropexy) had already been approved by the Local Ethics committee for our preliminary anatomoclinical published research and subsequently introduced in the clinical practice of the department. Therefore, this study had no need of further review by the local Institutional Review Board.

Abstract
AIM

To compare our developed nerve preserving technique with the non-nerve preserving one in terms of de novo bowel symptoms.

METHODS

Patients affected by symptomatic apical prolapse, admitted to our department and treated by nerve preserving laparoscopic sacropexy (LSP) between October, 2010 and April, 2013 (Group A or “interventional group”) were compared to those treated with the standard LSP, between September, 2007 and December, 2009 (Group B or “control group”). Functional and anatomical data were recorded prospectively at the first clinical review, at 1, 6 mo, and every postsurgical year. Questionnaires were filled in by the patients at each follow-up clinical evaluation.

RESULTS

Forty-three women were enrolled, 25/43 were treated by our nerve preserving technique and 18/43 by the standard one. The data from the interventional group were collected at a similar follow-up (> 18 mo) as those collected for the control group. No cases of de novo bowel dysfunction were observed in group A against 4 cases in group B (P = 0.02). Obstructed defecation syndrome (ODS) was highlighted by an increase in specific questionnaires scores and documented by the anorectal manometry. There were no cases of de novo constipation in the two groups. No major intraoperative complications were reported for our technique and it took no longer than the standard procedure. Apical recurrence and late complications were comparable in the two groups.

CONCLUSION

Our nerve preserving technique seems superior in terms of prevention of de novo bowel dysfunction compared to the standard one and had no major intraoperative complications.

Core tip: Laparoscopic sacropexy is associated with postoperative bowel dysfunction (constipation, obstructed defecation syndrome) in 10%-50% of cases, with significant worsening in the quality of life. Iatrogenic denervation of the autonomic pelvic nerves was reported as a relevant cause of this kind of dysfunction. The aim of this observational study was to evaluate the safety and efficacy of our nerve preserving technique.
