Insights
Laparoscopic pyloromyotomy offers a shorter hospital stay compared to open surgery for infants. This minimally invasive approach demonstrates comparable safety and efficacy, with potential cosmetic benefits.
Area of Science:
- Pediatric Surgery
- Minimally Invasive Surgery
Background:
- Laparoscopic pyloromyotomy techniques are emerging.
- Safety and efficacy of laparoscopic pyloromyotomy require further investigation.
Purpose of the Study:
- To compare outcomes of laparoscopic versus open pyloromyotomy in infants.
- To evaluate safety, efficacy, and patient benefits of laparoscopic pyloromyotomy.
Main Methods:
- Retrospective comparison of 37 infants undergoing open pyloromyotomy and 26 undergoing laparoscopic pyloromyotomy.
- Groups were matched for sex, age, weight, and presenting pH.
Main Results:
- Laparoscopic group had a shorter time from feeding to discharge (1.4 days vs. 1.8 days, p=0.04).
- Operating times were similar (29 min vs. 27 min).
- Complications were lower in the laparoscopic group (1 vs. 3).
Conclusions:
- Laparoscopic pyloromyotomy is comparable to open surgery in infants.
- Laparoscopic approach offers benefits of reduced hospital stay and improved cosmesis.
Abstract:
Several reports have appeared in the literature recently describing various techniques of performing pyloromyotomy laparoscopically. Although there is no doubt that this is now technically feasible, there are unanswered questions with regard to its safety, efficacy, and potential benefits or otherwise to the patient. In an attempt to resolve some of these issues, we compared the results in 37 infants who underwent open pyloromyotomy with 26 who underwent laparoscopic pyloromyotomy. The two groups were similar in terms of sex, age, weight, and presenting pH, although they could not be randomized. The time from feeding to discharge was less for the laparoscopic group (1.4 days) compared with the open group (1.8 days) (p = 0.04). Postoperative vomiting was not significantly different between the two groups. The operating time was identical for groups, 29 min vs 27 min. There were 3 complications in the open surgical group and 1 in the laparoscopic group. On the criteria measured, our results suggests that laparoscopic pyloromyotomy is at least as good as conventional surgery, and offers the potential benefits of shortened hospital stay and minimal cosmetic deformity.
