Surgical Management of Infantile Hypertrophic Pyloric Stenosis by Double-Y Pyloromyotomy: A Better Approach

Abstract

Background: Various treatment modalities have been applied for the management of infantile hypertrophic pyloric stenosis. However surgery remains the mainstay of treatment for IHPS of which Ramstedt's pyloromyotomy remains the surgical technique of choice.

Objective: To see the outcome of surgical management of infantile hypertrophic pyloric stenosis by double-Y pyloromyotomy.

Methods: A prospective interventional study of 40 patients with IHPS was carried out over a period of 2 years from July 2008 to July 2010. The patients were divided into 2 equal groups of 20 patients in each. All patients selected for study were optimized preoperatively regarding to hydration, acid-base status and electrolytes imbalance. All surgeries were performed after obtaining informed consent. Standard preoperative preparation and postoperative feeding regimes were used. The patients were operated on an alternate basis, i.e., one patient by Double-Y Pyloromyotomy (DY) and the next by a Ramstedt's Pyloromyotomy (RP). Data on patient demographics, operative time, anaesthesia complications and postoperative complications including vomiting and weight gain were collected. Patients were followed up for a period of 3 months postoperatively. Statistical assessments were done by using t test.

Results: From July 2008 through July 2010, forty patients were finally analyzed for this study. Any statistical differences were observed in patient population regarding age, sex, weight at presentation, symptoms and clinical condition including electrolytes imbalance and acid-base status were recorded. Significant differences were found in postoperative vomiting and weight gain. Data of post operative vomiting and weight gain in both groups were collected. Vomiting in double-Y(DY) pyloromyotomy group vs Ramstedt's pyloromyotomy (RP) group was significant (p= 0.0001). Weight gain after 1st 10 days DY vs RP is 298 ± 57.94 gm vs 193±19.8 gm (p=0.0014), after 1 month 676.67±149.84 gm vs 466.67 ± 127.71 gm (p=0.0001), after 2 months 741.33± 278.74 gm vs 490±80.62 gm (p=0.002) and after 3 months 582±36.01gm vs 453.33±51.64 gm (p=0.0001). No long-term complications were reported and no re-do pyloromyotomy was needed.

Conclusion: The double-Y pyloromyotomy seems to be a better technique for the surgical management of IHPS. It may offer a better functional outcome in term of postoperative vomiting and weight gain.
