Getting it right first time: implementation of laparoscopic pyloromyotomy without a learning curve

Area of Science:

• Pediatric Surgery
• Minimally Invasive Surgery
• Surgical Education

Background:

• Laparoscopic pyloromyotomy is a standard treatment for infantile hypertrophic pyloric stenosis.
• Implementation of this procedure can be associated with a learning curve, leading to higher complication rates like mucosal perforation and incomplete myotomy.
• A structured training program was developed to mitigate these risks.

Purpose of the Study:

• To describe a novel implementation strategy for laparoscopic pyloromyotomy.
• To demonstrate a method for introducing new surgical procedures while minimizing complications.
• To reduce the learning curve morbidity associated with laparoscopic pyloromyotomy.

Main Methods:

• A single surgeon piloted and refined the laparoscopic pyloromyotomy technique.
• This surgeon then mentored other consultants, ensuring consistent use of specific instruments and operative techniques.
• Data on patient outcomes and complications were prospectively collected.

Main Results:

• 140 laparoscopic pyloromyotomies were performed between 2013 and 2017, with 55% by trainees.
• A low complication rate of 1.4% was observed for mucosal perforation and incomplete pyloromyotomy.
• No other significant complications, such as organ injury or wound dehiscence, were reported; median discharge was one day post-operation.

Conclusions:

• The coordinated implementation strategy, emphasizing a single technique and structured mentoring, significantly reduced complications.
• This approach achieved complication rates comparable to the best published series for both open and laparoscopic pyloromyotomy.
• The findings highlight the importance of standardized training and reduced clinical variability for safe adoption of new surgical technologies.
