Official Description

Exploration, repair, and presacral drainage for rectal injury; with colostomy

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 45563 involves the exploration, repair, and presacral drainage for a rectal injury, specifically when a colostomy is also performed. This procedure is indicated in cases of penetrating injuries to the rectum, where the integrity of the rectal wall is compromised. The process begins with an abdominal exploration to identify the rectal injury, followed by controlling any bleeding that may be present. The rectal wound is then meticulously repaired using sutures to restore the normal anatomy. In instances where the injury necessitates a diversion of stool, a colostomy is created. This colostomy is typically fashioned from the sigmoid colon and serves to temporarily redirect fecal matter away from the rectum, allowing for healing. The colostomy can be performed using various techniques, including a loop colostomy, a loop colostomy with distal closure, or an end colostomy with a mucous fistula. After the abdominal procedure and the creation of the stoma, presacral drains are placed to facilitate drainage and prevent complications. The surgical approach includes making a curvilinear incision between the coccyx and the posterior margin of the anus, extending through the endopelvic fascia, and utilizing blunt dissection to access the presacral space and the site of the rectal injury. A drain is then inserted and secured to the perianal skin to ensure proper management of the surgical site.

1. Indications

The procedure described by CPT® Code 45563 is indicated for the management of penetrating injuries to the rectum. These injuries may arise from various causes, including trauma from accidents, surgical complications, or other forms of external force that compromise the rectal wall integrity. The primary goal of this procedure is to explore the injury, repair any damage, and manage potential complications such as bleeding or infection.

  • Penetrating Rectal Injury A condition where the rectum is injured due to external trauma, necessitating surgical intervention for repair and drainage.

2. Procedure

The procedure involves several critical steps to ensure effective management of the rectal injury. Each step is designed to address the injury comprehensively and safely.

  • Step 1: Abdominal Exploration The procedure begins with an incision to open the abdomen, allowing the surgeon to explore the abdominal cavity. This exploration is crucial for identifying the site and extent of the rectal injury, as well as assessing any associated injuries to surrounding structures.
  • Step 2: Identification and Control of Bleeding Once the rectal injury is located, the surgeon takes immediate action to control any bleeding. This may involve cauterization or ligation of blood vessels to stabilize the patient and prevent further complications.
  • Step 3: Rectal Wound Repair After controlling the bleeding, the rectal wound is repaired using sutures. This step is vital for restoring the integrity of the rectal wall and ensuring proper healing.
  • Step 4: Colostomy Creation Depending on the nature of the injury, a colostomy may be performed to divert stool away from the rectum. The colostomy is typically created from the sigmoid colon and can be done using various techniques, such as a loop colostomy, loop colostomy with distal closure, or an end colostomy with a mucous fistula.
  • Step 5: Placement of Presacral Drains Following the abdominal procedure and stoma creation, presacral drains are placed to facilitate drainage from the surgical site. This helps to prevent fluid accumulation and reduces the risk of infection.
  • Step 6: Incision and Dissection A curvilinear incision is made between the coccyx and the posterior margin of the anus. The incision is extended through the endopelvic fascia, and blunt dissection is performed to open the presacral space. This dissection continues until the site of the rectal injury is reached.
  • Step 7: Drain Insertion Finally, a drain is inserted to the level of the rectal injury and secured to the perianal skin. This ensures proper drainage and monitoring of the surgical site post-procedure.

3. Post-Procedure

After the completion of the procedure, patients are typically monitored for any signs of complications, such as infection or bleeding. The presence of presacral drains allows for effective management of any fluid accumulation. Patients may require additional care and follow-up appointments to assess the healing of the rectal repair and the colostomy site. Instructions regarding colostomy care, dietary modifications, and activity restrictions may also be provided to ensure optimal recovery.
