Laparoscopic pyloromyotomy: Lessons learnt in our first 101 cases.

Area of Science:

• Pediatric Surgery
• Minimally Invasive Surgery

Background:

• Infantile hypertrophic pyloric stenosis (IHPS) is a common surgical condition in infants.
• Laparoscopic pyloromyotomy has become a preferred surgical approach for IHPS.

Purpose of the Study:

• To evaluate the safety and efficacy of laparoscopic pyloromyotomy for IHPS.
• To analyze the impact of the learning curve on surgical outcomes.

Main Methods:

• Retrospective analysis of 101 infants undergoing laparoscopic pyloromyotomy over six years.
• Comparison of outcomes between early (2007-2009) and later (2010-2013) surgical periods.

Main Results:

• Mean operative time decreased from 49.7 to 43.0 minutes.
• Conversion rates dropped from 9.3% to 0%, and mucosal perforation rates decreased from 6.9% to 1.7%.
• Inadequate pylorotomy rates were noted as high and require further attention.

Conclusions:

• Laparoscopic pyloromyotomy is a safe procedure for IHPS with minimal morbidity.
• Surgical experience improves outcomes, reducing operative times and complications.
• Continuous learning and technique refinement are essential to minimize inadequate pylorotomy rates.
