LAPAROSCOPIC EXPLORATION FOR INFANTILE HYPERTROPHIC PYLORIC STENOSIS: AN EXPERIENCE AT TERTIARY CARE HOSPITAL

Objectives: This study aims to share our experience of laparoscopic exploration for infantile hypertrophic pyloric stenosis. Material and methods: This retrospective study was conducted in the Department of Pediatric Surgery, Khyber Teaching Hospital, Peshawar from June 2017 to July 2020. This study includes all patients whose diagnosis of infantile hypertrophic pyloric stenosis (IHPS) was confirmed through ultrasound parameters and laparoscopic pyloromyotomy was performed. Data was retrieved from the laparoscopic surgery record. Retrieved data was tabulated and fed in SPSS 25 for analysis. Results: This study included 42 patients with a mean age of 50.28 ±18.5days and a mean weight of 3.35±0.76 kg. Male patients were 57 % while females were 43 %. The mean time to resuscitate the patient pre-operatively was 34.6±15.4 hours while the mean postoperative hospital stay was 45±12.47 hours. The mean operative time was 31.6±10.4 min. Operative time decreased with time depicting improvement in our learning curve (p=0.004). The method of working instrument placement had no impact on operative time (p=0.337). Meantime to full oral feed was 9.7±5.1 hours. We did not encounter mucosal perforation or incomplete myotomy. No surgery was converted to open. Conclusion: Laparoscopic pyloromyotomy is a safe and effective method of treatment for infantile hypertrophic pyloric stenosis. Keywords:  laparoscopic pyloromyotomy, pyloric stenosis, IHPS
