Open Approaches for Rectal Prolapse John Hartley Academic Surgical Unit University of Hull
Open operations for rectal prolapse • Perineal operations inferior to abdominal procedures, but definite role • Delorme’s procedure – simple but high recurrence rate, can be repeated • Perineal rectosigmoidectomy – more complex but lower recurrence rate • “If the patient is fit enough and life expectancy > 5yrs abdominal approach preferred” Keighley and Williams 2nd Edition 2001
Open operations for rectal prolapse The realities – Yorkshire colon and rectal surgery
Open operations for rectal prolapse A range of possibilities: • Exclusion procedures • Pelvic floor repair • Anterior or posterior rectopexy • Resection – alone or with rectopexy
Open operations for rectal prolapse Sigmoid exclusion procedure (Lahaut’s operation) • Rectum fully mobilised in pelvis • Rectosigmoid sutured to posterior rectus sheath • Sigmoid extra-peritonealised behind rectus muscle
Open operations for rectal prolapse Lahaut’s operation • 33 pts • 1 death (3%) • No recurrences • 11 of 12 pts improved continence • One faecal fistula (?ischaemic) • One obstruction Mortensen et al Ann R Coll Surg Engl 1984:66:17 18
Open operations for rectal prolapse Pelvic floor repair via the abdomen • Full anterior and posterior mobilisation of the rectum • Repair of pelvic floor posterior (originally ant and post) to rectum • Difficult access • Pelvic floor thin and attenuated • Largely replaced by rectopexy
Results of abdominal pelvic floor repair for prolapse From Keighley and Williams 2001
Open procedures for rectal prolapse Rectopexy • Probably the operation of choice • Recurrence rates approx. 2% • Continence restored in 60-80% with rectopexy alone • How should rectum be fixed? • When should resection be added?
Open operations for rectal prolapse Anterior rectopexy (Ripstein procedure) • Full mobilisation of rectum • Fixation to sacral promontary by sling (polypropylene, teflon or fascia) • Principle complication – fibrous stricture
Anterior rectopexy From Keighley and Williams 2001
Open operations for rectal prolapse Posterior rectopexy • Posterior aspect of fully mobilised rectum attached to sacrum • Lateral peritoneum divided, posterior mobilisation to tip of coccyx, division of lateral ligaments • No anterior restriction, distensible rectum • Mesh to sacrum and lateral aspects rectum
Posterior rectopexy Method of fixation • Teflon • Polypropylene (marlex) • Polyvinyl alcohol sponge (Well’s procedure) - infection (recurrence) • Vicryl • Gore-Tex • SIMPLE SUTURES
Posterior rectopexy (suture only) From Keighley and Williams 2001

Open operations for rectal prolapse Resection alone • Sigmoid or partial rectal resection (n=113) • Incontinence: - Improved 23 (20%) - Same 13 (11%) - Worse 10 (9%) • Sepsis morbidity: 52% after “low” and 19% after high anastomosis • Recurrence at 10 yrs 14% after “high” and 9% after “low” resections Schlinkert et al Dis Colon Rectum 1985:28:409-412
Resection Rectopexy • Aims to achieve low recurrence rates and avoid long term constipation University of Minnesota series • 138 pts • Anastomotic leaks in 5 (4%) • Recurrent prolapse in 2 (1.4%) • Continence improved in all but 1 pt • Constipation improved in 56% same in 35% worse in 9% Watts et al. Dis Colon Rectum 1985;28:96-102.

Open Approaches for Rectal Prolapse Summary • Lower recurrence rates but higher morbidity than perineal procedures • Fixation superior to pelvic floor repair, or resection alone • Posterior fixation superior results • Sutures alone comparable to mesh fixation • Less constipation with concomitant resection
Open Approaches for Rectal Prolapse Conclusions Sigmoid resection with sutured rectopexy offers: • Low risk of recurrence • The long term avoidance of constipation • PROCEDURE OF CHOICE • (why not laparoscopically?)
