A novel two-port single-site laparoscopic pyloromyotomy for infantile hypertrophic pyloric stenosis

Objective: The objective of the study is to explore a less invasive laparoscopic pyloromyotomy for treating infantile hypertrophic pyloric stenosis. Patients and Methods: A series of 154 cases from January 2014 to January 2020 were retrospectively analysed. Seventy patients were treated with the method of transumbilical single-site laparoscopic pyloromyotomy (SSLP), and 84 patients were treated with two-site laparoscopic pyloromyotomy. There was no difference in the body weight, sex ratio or age between the two groups. The operation time, blood loss, post-operative feeding time and complications between the two groups were compared. Results: The novel single-site method had better cosmetic effect than the two-site approach. There was no difference in the operation time, blood loss, post-operative feeding time or complications between the two groups. Conclusion: The novel SSLP method requires only two incisions through the umbilicus to complete the procedure, with barely visible scars and similar surgical complications to that of the two-site approach; thus, the novel method is worth promoting.
