ABSTRACT
AIM:
The aim of this study is to evaluate the short- and long-term efficacy of sacral nerve stimulation (SNS) for treating slow-transit constipation (STC).METHOD:
This is a retrospective cohort analysis of the efficacy of SNS in treating patients affected by STC, who previously failed to respond to conservative therapies. Only patients free of concomitant diseases were enrolled in our study. A temporary stimulation lead was initially implanted; patients with a > 50% symptom reduction were eventually deemed eligible for a permanent implant.RESULTS:
This study enrolled 25 patients who underwent a SNS test stimulation; 21 patients (13 women; median age 32 years) eventually got a permanent implant. The median preoperative Cleveland Clinic Constipation Score (CCCS) was 21 (16-25). Preoperative colorectal transit time recorded a median of 10 markers (7-19) retained in the colorectal tract. At 6-month postoperative follow-up, the total number of markers retained in the colorectal tract decreased to 3 (0-4). The CCCS score improved during the first postoperative year (P < 0.001), but progressively worsened over the longer term. The SF-36 questionnaire showed an improvement in all 8 scales measuring physical and psycho-emotional states; all parameters recorded into the bowel diary also improved. Overall, at 60-month follow up, the overall neuromodulator removal rate was 48%.CONCLUSIONS:
The SNS is a minimally invasive surgical procedure that we tested for treating STC. The short-term outcome was promisingly after 6 months; however, there was a declining trend beyond this interval. Thus, the long-term efficacy of SNS needs to be further assessed.Palabras clave
