Intraabdominal pyloromyotomy through the umbilical route: a technical improvement

Area of Science:

• Pediatric Surgery
• Surgical Oncology

Background:

• Supraumbilical skin fold incision for pyloromyotomy offers cosmetic advantages with minimal scarring.
• Conventional right upper quadrant incisions may present challenges with large pyloric tumors.

Purpose of the Study:

• To evaluate the efficacy and safety of intra-abdominal (in situ) pyloromyotomy via an umbilical approach.
• To assess cosmetic outcomes and technical feasibility compared to traditional methods.

Main Methods:

• Retrospective review of 29 infants undergoing intra-abdominal pyloromyotomy through the umbilical route.
• Analysis of medical records from January 1990 to August 1996 for infantile hypertrophic pyloric stenosis.

Main Results:

• The median hospital stay was 2.5 days.
• Two intraoperative mucosal perforations and one postoperative abscess occurred, requiring drainage.
• The procedure was performed on 29 infants (23 boys, 6 girls) aged 17-70 days.

Conclusions:

• Intra-abdominal pyloromyotomy through the umbilical route is an effective alternative for infantile hypertrophic pyloric stenosis.
• This technique is particularly advantageous for managing large pyloric tumors, offering superior cosmetic results.
