title: Esophagotomy during laparoscopic Heller myotomy cannot be predicted by preoperative therapies and does not influence long-term outcome.
abstract: The conventional wisdom is that inadvertent esophagotomy complicates laparoscopic Heller myotomy. This study was undertaken to determine if esophagotomy at myotomy can be predicted by preoperative therapy, and if esophagotomy and/or its repair jeopardizes outcomes. Of 222 laparoscopic Heller myotomies undertaken since 1992, inadvertent esophagotomy occurred in 16 patients (7%); 60 patients who underwent myotomy without esophagotomy were utilized for comparison. Dysphagia and reflux before/after myotomy were scored by patients on a Likert scale (0-5). The median (mean +/- SD) follow-up after myotomy with esophagotomy was 38.8 months (31.6 +/- 21.9 months) versus 46.3 months (51.0 +/- 21.2 months) after myotomy alone. All esophagotomies were immediately recognized and repaired. Patients who experienced esophagotomy were similar to those who did not in application of Botox (56% vs. 77%) or dilation (44% vs. 65%), years of dysphagia (7.3 +/- 5.4 vs. 7.4 +/- 6.0), and mean preoperative dysphagia score (4.9 +/- 0.4 vs. 4.8 +/- 0.4). Esophagotomy led to longer hospitalizations (5.2 days +/- 2.5 days vs. 1.5 days +/- 0.7 days, P < 0.05) but not different postoperative dysphagia scores (1.5 +/- 1.7 vs. 2.1 +/- 1.4), reflux scores (1.4 +/- 1.7 vs. 2.3 +/- 1.3), or good or excellent outcomes (86% vs 84%). Esophagotomy during laparoscopic Heller myotomy is infrequent and cannot be predicted by preoperative therapy or duration or severity of dysphagia. Furthermore, complications after esophagotomy are infrequent and outcomes are indistinguishable from those of patients undergoing uneventful myotomy.
