According to a research published in "Annals of Pediatric Surgery", the Hill-Snow operation is a useful substitute for Nissen fundoplication that causes no bloating, significantly less dysphagia, and leads to faster recovery of regular eating habits. Researchers compared the effectiveness and safety of laparoscopic Nissen fundoplication to the Hill-Snow surgery to combat gastroesophageal reflux disease (GERD) in children.

A total of 40 children with GERD were enrolled in this randomized, comparative, single-blinded trial and were scheduled to undergo surgery. The children were randomly assigned to the Hill-Snow operation or laparoscopic Nissen fundoplication. Although both groups experienced postoperative dysphagia at a comparable rate, the Hill-Snow group's dysphagia lasted for noticeably less time. Moreover, the Hill-Snow group had substantially less bloating than the Nissen group (0% vs. 55%, respectively).

Compared to 2 recurrent Nissen cases, three recurrent Hill-Snow cases were discovered. The Hill-Snow method (150 ± 52 min) had a substantially longer operative time  than the Nissen group (120 ± 48 min). Hence, the Hill-Snow procedure is a promising substitute for Nissen fundoplication to relieve GERD in children.
