Official Description

Pyloroplasty

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure known as pyloroplasty involves the surgical modification of the pyloric sphincter, which is a muscular valve located at the lower end of the stomach. This sphincter plays a critical role in regulating the passage of food from the stomach into the duodenum, the first part of the small intestine. Under normal circumstances, the pyloric sphincter prevents the backflow of contents from the duodenum into the stomach, thereby maintaining proper digestive function. However, in cases where the sphincter becomes excessively tight, a condition termed pyloric stenosis can occur. This condition can lead to complications such as gastroesophageal reflux, where stomach contents flow back into the esophagus, or peptic ulcer disease, which is characterized by sores on the stomach lining. The primary objective of pyloroplasty is to alleviate the tightness of the sphincter, thereby enhancing the flow of food into the duodenum. The surgical technique involves making a midline incision in the abdominal wall to access the stomach and duodenum. Once exposed, the pylorus is carefully divided laterally and then sutured in a longitudinal manner to create a wider opening, facilitating improved passage of food. Finally, the abdominal incision is meticulously closed in layers to promote proper healing and recovery.

1. Indications

The pyloroplasty procedure is indicated for patients experiencing conditions related to the dysfunction of the pyloric sphincter. These indications include:

  • Pyloric Stenosis - A condition characterized by the narrowing of the pyloric sphincter, which impedes the normal passage of food from the stomach to the duodenum.
  • Gastroesophageal Reflux - A disorder where stomach contents flow back into the esophagus, often due to the inability of the pyloric sphincter to maintain proper closure.
  • Peptic Ulcer Disease - A condition involving sores on the stomach lining, which may be exacerbated by delayed gastric emptying caused by a tight pyloric sphincter.

2. Procedure

The pyloroplasty procedure consists of several critical steps that ensure the effective widening of the pyloric sphincter. These steps include:

  • Step 1: Anesthesia Administration - The patient is placed under general anesthesia to ensure comfort and immobility during the surgical procedure.
  • Step 2: Abdominal Incision - A midline incision is made in the abdominal wall, allowing access to the stomach and duodenum. This incision is typically made from the xiphoid process to the umbilicus.
  • Step 3: Exposure of the Stomach and Duodenum - The surgeon carefully dissects the surrounding tissues to expose the stomach and the duodenum, ensuring that the pyloric sphincter is clearly visible for the next steps.
  • Step 4: Division of the Pylorus - The pylorus is then divided laterally, which involves making an incision along the side of the sphincter to facilitate the widening of the opening.
  • Step 5: Suturing the Pylorus - After the division, the pylorus is sutured longitudinally. This technique creates a larger opening into the duodenum, allowing for improved passage of food.
  • Step 6: Closure of the Abdominal Incision - Finally, the abdominal incision is closed in layers, ensuring that the underlying tissues are properly aligned and that the skin is sutured securely to promote healing.

3. Post-Procedure

After the pyloroplasty procedure, patients are typically monitored in a recovery area until the effects of anesthesia wear off. Post-operative care may include pain management, monitoring for any signs of complications, and gradual reintroduction of oral intake as tolerated. Patients are usually advised to follow a specific diet and may require follow-up visits to assess recovery and ensure that the pylorus is functioning properly. It is essential to adhere to the surgeon's post-operative instructions to promote optimal healing and recovery.

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.
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
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.)
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
