Delorme’s procedure in rectal prolapse - general and visceral surgery

With the patient in lithotomy position, perform a digital rectal examination followed by slow and careful dilation of the anal sphincter. Insert the Parks retractor

Injection into the anterior rectal mucosa, horizontal mucosal incision 5-8 mm proximal to the dentate line and careful excision of a longitudinally ovoid mucosal flap of up to 10 x 8 cm in size in cranial direction with diathermy while sparing the underlying muscle coat. Carry out the dissection in semicircular fashion, from 9 o'clock to 3 o'clock horizontally and vertically along the entire length of the rectocele.

Gradually plicate the anterior rectal wall in the vertical direction with several absorbable sutures (size 0). This usually requires 5 - 8 stitches. The muscularis mucosae may be concertinaed or fixed in three layers.

Resect the excess mucosa and then adapt the mucosal margins.
