Pyloromyotomy: randomized control trial of laparoscopic vs open technique

Area of Science:

• Pediatric Surgery
• Surgical Techniques
• Gastroenterology

Background:

• Open pyloromyotomy is the standard treatment for hypertrophic pyloric stenosis.
• Laparoscopic pyloromyotomy is increasingly adopted for this condition.

Purpose of the Study:

• To compare open versus laparoscopic pyloromyotomy in a prospective, randomized trial.
• Evaluate outcomes including operating time, complications, and long-term results.

Main Methods:

• 98 patients with hypertrophic pyloric stenosis were randomized to open or laparoscopic pyloromyotomy.
• Outcomes assessed included operating room time, postoperative stay, refeeding, complications, cosmetic results, and parental satisfaction.

Main Results:

• No significant differences were found between the two groups for primary outcomes.
• Complication rates were similar: 3 in the open group and 2 in the laparoscopic group.
• Long-term follow-up (56 months) showed significantly superior cosmetic results with the laparoscopic approach.

Conclusions:

• Both open and laparoscopic pyloromyotomy have similar outcomes regarding operating time, hospital stay, and refeeding.
• Complication rates are comparable between the two surgical methods.
• Laparoscopic pyloromyotomy provides significantly better long-term cosmetic outcomes.
