Minimal esophagus dissection without approximating the hiatus in laparoscopic fundoplication in pediatric population.

OBJECTIVE: An important part of laparoscopic Nissen's fundoplication (LNF) is a proper wrap, which may only be possible with proper dissection of esophagus and hiatus. However, too much dissection of esophagus and hiatus to gain sufficient length of esophagus increases morbidity. The aim of this study is to analyze the effect of minimal esophagus dissection in LNF on recurrence and post-operative hiatal hernia.

METHODS: The present study includes the children (0-18 years) who underwent LNF with minimal esophagus dissection and without hiatal closure between 2008 and 2016. The charts of the patients analyzed retrospectively and evaluated in terms of recurrence and post-operative hiatal hernia.

RESULTS: There were 143 children. Mean age was 4.5±4.6 year (20 days-17 years). About 54% of the children (n=78) were neurologically impaired. There were two temporary intestinal obstructions which did not require surgery, one esophageal tightness which resolved with one dilatation session and one recurrence with hiatal hernia which required reoperation.

CONCLUSION: Minimal esophagus dissection without hiatal closure in LNF avoids dysphagia with no increase in the rate of recurrence and complications.
