Laparoscopic Treatment of Simultaneously Occurring Pyloric Stenosis and Malrotation

Abstract

Hypertrophic pyloric stenosis (HPS) is a common cause of nonbilious vomiting in the neonatal period with an incidence of approximately 1 to 3 per 1000 live births. The Ramstedt pyloromyotomy has been the standard treatment since 1912. In 1991, Alain et al. reported a novel approach to HPS using laparoscopy. Since this original description, the laparoscopic pyloromyotomy has become progressively more popular and, in many institutions, has replaced the open approach. Similarly, malrotation is a condition affecting the neonatal population, resulting from incomplete intestinal rotation about the superior mesenteric artery during weeks 10 through 11 of development. If left untreated, it can lead to abnormal mesenteric attachments and a narrowed mesenteric base, placing the patient at risk for midgut volvulus. The standard surgical treatment has been the open Ladd procedure first described in 1932. In 1996, Gross described a minimally invasive procedure to address malrotation. The association of concurrent pyloric stenosis and malrotation has rarely been reported in the pediatric literature. This is the first published report of a laparoscopic treatment of HPS and malrotation simultaneously.
