Dorsal approach to rectum

Contributor(s): Daniel Smeak

Introduction

  • Surgical access to the caudal or middle rectum but not the anal canal; dorsal lateral exposure to perirectal tissues.

Uses

  • Removal of rectal lesions.
  • Removal or biopsy of perirectal lesions.
  • Repair of rectal lacerations.

Advantages

  • Reasonable access to dorsal - lateral lesions.
  • Allows segmental resection and anastomosis of rectal lesions, and removal of masses with resection of part of the rectal wall.

Disadvantages

  • Provides poor exposure to lateral or ventral lesions that require partial wall resection.
  • Intra-operative contamination difficult to control.

Prognosis

  • Depends on original lesion and whether it was fully removed or repaired.
  • Relatively few complications and problems relating to prognosis from dorsal approach itself.
  • Benign isolated lesions that can be fully removed, and benign perirectal lesions have a good prognosis.
