Stapled rectal mucosectomy alone and in combination with other surgical anorectal procedures: multivariate analysis of factors affecting clinical outcome.
BACKGROUND
We undertook this study to compare the clinical outcome of stapled rectal mucosectomy (SRM) alone and in combination with sphincterotomy and cutaneous flap anoplasty and to determine the influence of factors related to complications and patient satisfaction.


METHODS
Patients with second- to fourth-degree hemorrhoids who underwent SRM alone or in combination with other anorectal procedures were included. Postoperative complications, symptom resolution and patient satisfaction were analyzed.


RESULTS
Two hundred forty one patients with a minimum follow-up of 1 year were divided into three groups: SRM alone (n = 187), SRM combined with sphincterotomy (n = 31) and SRM combined with cutaneous flap anoplasty (n = 23). Patients with SRM with sphincterotomy showed a higher complication rate than the other groups (32 vs. 12.8% and 13%, respectively, p = 0.02). SRM combined with sphincterotomy was associated with a higher rate of complications (OR = 3.5; 95% CI = 1.4-8.7). SRM alone with low mucosal resection was associated with a lower complications rate (OR = 0.4, 95% CI = 0.2-0.8). Resolution of preoperative symptoms was >80% among the three groups. There was no association between complications and type of procedure with satisfaction level. Resolution of symptoms <80% was associated with low/intermediate level of satisfaction (p <0.001).


CONCLUSIONS
Resolution of preoperative symptoms is similar among the three groups. SRM combined with sphincterotomy has a higher risk of complications. The satisfaction level is associated with resolution of preoperative symptoms.
