Evaluation of Delorme's procedure as a treatment for full-thickness rectal prolapse

Delorme's procedure is a well tolerated perineal operation for full-thickness rectal prolapse. However, prolapse recurrence is common and reported recurrence rates vary widely. This study attempted to standardize outcome assessment for recurrence following primary and subsequent Delorme's operations. Patient and operative factors were analysed to identify any that might improve patient selection.

Some 101 primary and 17 secondary Delorme's procedures were carried out on 113 consecutive patients presenting with rectal prolapse, who were followed for a minimum of 12 months, unless death or recurrent prolapse intervened. The rate of prolapse recurrence was calculated using the Kaplan-Meier method of analysis. Patient age, sex, grade of incontinence, presence of diverticular disease, length of mucosal resection and position in the operative series were analysed to identify factors affecting recurrence.

The predicted recurrence-free period for 50 per cent of patients undergoing primary and secondary Delorme's procedures was 91 (95 per cent confidence interval 77-105) and 27 (15-39) months respectively. None of the patient or operative factors analysed was related to recurrent prolapse.

Delorme's procedure is a simple operation with satisfactory functional results which can be considered in all patients of all ages. However, high recurrence rates for primary and repeat operations should be explained to patients when planning their surgical management.
