Official Description

Excision of rectal procidentia, with anastomosis; abdominal and perineal approach

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Excision of rectal procidentia, with anastomosis, is a surgical procedure designated by CPT® Code 45135. This procedure addresses rectal procidentia, which is characterized by a complete prolapse of the rectum, where the entire thickness of the rectal wall protrudes through the anal opening. The surgical intervention involves a combined approach, utilizing both abdominal and perineal techniques to effectively remove the prolapsed rectum and restore normal anatomy. The procedure is essential for patients suffering from this condition, as it alleviates symptoms associated with rectal prolapse, such as discomfort, incontinence, and potential complications from the prolapse itself. The operation is performed under general anesthesia, and the patient is typically positioned in lithotomy to facilitate access to the perineum and abdominal cavity. The complexity of the procedure requires careful dissection and mobilization of the rectum and surrounding structures to ensure successful excision and anastomosis, ultimately aiming to preserve the function of the anal mucosa and maintain bowel continuity.

1. Indications

The excision of rectal procidentia with anastomosis is indicated for patients presenting with the following conditions:

  • Rectal Procidentia A complete prolapse of the rectum, where the rectal wall protrudes through the anal opening, leading to significant discomfort and potential complications.
  • Incontinence Symptoms of fecal incontinence that may arise due to the structural changes associated with rectal prolapse.
  • Discomfort Persistent pain or discomfort in the anal region that affects the patient's quality of life.
  • Complications Potential complications from the prolapse, such as ulceration, bleeding, or infection.

2. Procedure

The procedure for excision of rectal procidentia with anastomosis involves several critical steps:

  • Step 1: Positioning and Exposure The patient is placed in the lithotomy position to allow optimal access to the perineum. The perineum is then exposed for surgical intervention.
  • Step 2: Perineal Incision An incision is made in the perineum, and the outer layer of the bowel wall is divided in a circular fashion to facilitate access to the rectum.
  • Step 3: Dissection of the Rectum The rectum is carefully freed from its pelvic and abdominal attachments by dividing the surrounding fat and mesentery, continuing this dissection up to a point just above the dentate line.
  • Step 4: Abdominal Incision An abdominal incision is made to access the abdominal cavity. The sigmoid colon and rectum are mobilized up to the level of the levator ligaments.
  • Step 5: Division of Ligaments The lateral ligaments are divided, and the remaining structures are sutured to the presacral fascia to maintain stability during the procedure.
  • Step 6: Resection A portion of the sigmoid colon and the entire rectum are excised, ensuring that the inferior mesenteric artery is preserved to maintain blood supply.
  • Step 7: Anastomosis The anal mucosa is then anastomosed to the remaining segment of the sigmoid colon, restoring continuity of the bowel.
  • Step 8: Closure Finally, the abdominal incisions are closed in a layered fashion to promote proper healing and minimize complications.

3. Post-Procedure

Post-procedure care for patients undergoing excision of rectal procidentia with anastomosis includes monitoring for any signs of complications such as infection, bleeding, or anastomotic leakage. Patients are typically advised to follow a specific diet to ease bowel movements and may require pain management strategies. Follow-up appointments are essential to assess healing and ensure that the anastomosis is functioning properly. Patients may also receive guidance on pelvic floor exercises to aid in recovery and improve bowel function.

22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
