[Outcome of laparoscopic Heller myotomy in children].

AIM: The appropriate management of achalasia in children remains debatable. The present study aimed to evaluate the outcome of laparoscopic Heller myotomy by assessing short- and mid-term issues.

METHODS

Children submitted to surgery from 2002 to 2010 were included. Surgery was proposed after failure of endoscopic dilatations. All patients underwent esophagocardiomyotomy (Heller) plus anterior fundoplication (Dor) by laparoscopy. Demographics, presentation symptoms and perioperative details were analyzed. The outcomes were assessed both by medical records and the application of a 14 items (score 0-worst to 4-best/normal) self-evaluation questionnaire (modified GIQLI - covering only upper gastrointestinal symptoms).

RESULTS

Six patients (5 males) with a median age of 12.2 years (range: 0.8-14.2) were submitted to surgery. The presenting symptoms were: dysphagia (83.3%), weight loss (50%), vomiting (33.3%), chronic cough (33.3%), and chest pain (16.7%). All patients were operated on by laparoscopy with no conversions; there were no intra or postoperative complications. At a median follow-up of 5 years (range: 2-10) none of the patients were re-operated. Five patients have normal eating habits; the remaining case presented recurrent episodes of dysphagia requiring regular endoscopic dilatations (every 6 months). The total GIQLI presented a mean score of 49.3 (range, 45-52) representing 88.1% of the theoretical maximum. The score for frequency of dysphagia episodes was 1.6 +/- 1.4; all patients scored 3 for the grade of dysphagia.

CONCLUSIONS

Laparoscopic Heller myotomy is effective and safe for achalasia in children, offering a good and durable quality of life; although frequent, the dysphagia episodes were mild.
