Summary
Laparoscopic pyloromyotomy (LP) shows a higher risk of specific complications compared to open procedures (OP), but this risk decreases with surgeon experience. Non-specific complication rates remained stable for open surgery.
Area of Science:
- Pediatric surgery
- Surgical education
Background:
- Hypertrophic pyloric stenosis (HPS) requires surgical intervention.
- Open pyloromyotomy (OP) and laparoscopic pyloromyotomy (LP) are common surgical techniques for HPS.
Purpose of the Study:
- To compare the learning curves of OP and LP surgical techniques.
- To evaluate the impact of these techniques on completion times and postoperative outcomes/complications.
Main Methods:
- Retrospective analysis of 198 patients with HPS.
- Comparison of complication rates between surgeons performing OP (106 cases) and LP (92 cases).
- Logistic regression analysis to assess complication occurrence.
Main Results:
- Overall postoperative complication rates were similar: 15.1% for OP and 11.8% for LP.
- LP group had higher specific complication rates (6.4% vs 2.8%).
- OP group had higher non-specific complication rates (12.1% vs 5.3%).
- Complication risk decreased with experience in the LP group (p=0.0067) but not in the OP group (p=0.9665).
Conclusions:
- Laparoscopic pyloromyotomy is associated with a higher initial risk of specific complications.
- Surgical experience significantly reduces complication risk in LP.
- Non-specific complication rates are stable in OP regardless of experience.
