Official Description

Enterectomy, resection of small intestine for congenital atresia, single resection and anastomosis of proximal segment of intestine; with tapering

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 44127 involves an enterectomy, which is a surgical resection of a segment of the small intestine. This specific procedure is performed to address congenital atresia, a condition characterized by a complete obstruction of the small intestine that leads to the dilation of the intestinal segment located proximal to the obstruction site. In cases of congenital atresia, the affected segment of the intestine cannot function properly, resulting in potential complications such as abdominal distension and hypertrophy of the pylorus. The surgical approach typically involves a midline incision in the abdomen, allowing the surgeon to access and inspect the abdominal contents, including vital organs such as the liver and gallbladder. During the procedure, the surgeon identifies the dilated section of the small intestine, carefully dissects it from surrounding tissues, and manages blood vessels through clamping and ligation. The obstructed segment is then excised, and the remaining proximal and distal segments of the intestine are joined together through anastomosis. A key aspect of this procedure is the tapering of the dilated proximal segment, which is achieved by creating folds on the lateral antimesenteric side, thereby facilitating a more effective connection between the two segments. This tapering technique distinguishes CPT® Code 44127 from similar codes, such as 44126, which does not involve tapering. The procedure is critical for restoring intestinal continuity and function in patients with congenital atresia.

1. Indications

The procedure described by CPT® Code 44127 is indicated for the treatment of congenital atresia of the small intestine. This condition is characterized by the following:

  • Congenital Atresia - A birth defect resulting in a complete obstruction of the small intestine, leading to the dilation of the proximal segment.
  • Abdominal Distension - The accumulation of fluid and gas in the dilated segment, causing visible swelling of the abdomen.
  • Pyloric Hypertrophy - Thickening of the pylorus, which may occur due to the obstruction, resulting in further complications.

2. Procedure

The procedure for CPT® Code 44127 involves several critical steps to ensure successful resection and anastomosis of the small intestine:

  • Step 1: Incision - A midline incision is made in the abdominal wall to provide access to the abdominal cavity. This allows the surgeon to visualize and assess the internal organs, including the liver and gallbladder.
  • Step 2: Identification and Dissection - The surgeon identifies the dilated section of the small intestine that is obstructed due to congenital atresia. This segment is carefully dissected free from surrounding tissues to minimize damage to adjacent structures.
  • Step 3: Vascular Control - Blood vessels supplying the affected segment are clamped and ligated as necessary to control bleeding during the procedure.
  • Step 4: Resection - The dilated segment of the small intestine is excised using staples or noncrushing clamps to ensure a clean cut without damaging the remaining intestinal tissue.
  • Step 5: Anastomosis - The remaining proximal and distal segments of the small intestine are sutured together. In this procedure, the proximal segment is tapered by creating folds on the lateral antimesenteric side, which helps to facilitate a more effective anastomosis.
  • Step 6: Closure - After ensuring that the anastomosis is secure and there are no leaks, the abdominal cavity is closed in layers, and the incision is sutured.

3. Post-Procedure

Post-procedure care following an enterectomy for congenital atresia typically involves monitoring the patient for any signs of complications, such as infection or anastomotic leaks. Patients may require intravenous fluids initially and will gradually transition to oral intake as tolerated. Pain management is also an essential aspect of post-operative care. The recovery period may vary depending on the individual patient's condition and the extent of the surgery performed. Follow-up appointments are necessary to assess healing and ensure proper intestinal function.
