The respiratory advantage of laparoscopic Nissen fundoplication.

Background/purpose: Laparoscopic Nissen fundoplication is replacing the open approach in the treatment of children with gastroesophageal reflux. The postoperative respiratory advantages seem obvious but remain unproven. The authors hypothesized that laparoscopic Nissen fundoplication provides postoperative respiratory advantages in neurologically normal children as well as those with mental retardation or profound neurologic impairment.
Methods: The charts of all laparoscopic Nissen fundoplications over a 4-year period were reviewed. Sixty-one laparoscopic procedures were compared with the most recent 61 consecutive open Nissen fundoplications. The following variables were reviewed: age, weight, gender, preexisting comorbidities, operating time, postoperative pulmonary complications, and length of stay. Categorical data were compared for significance utilizing chi2 cross tabulation. Variables representing numerical data were compared by t test.
Results: Although there appeared to be a trend toward sicker patients in the open group, the laparoscopic group showed significantly improved rates of extubation, shorter recovery room stays, shorter durations of chest physiotherapy, fewer intensive care unit admissions, more rapid resumption of baseline feedings, and overall decreased length of stay (P < 0.05). Pulmonary benefits also were noted in the neurologically impaired population when analyzed separately.
Conclusions: Laparoscopic Nissen fundoplication confers a definable benefit with a significant pulmonary advantage in both neurologically normal children and those with neurologic impairment.
