Laparoscopic transhiatal approach for benign supra-diaphragmatic lesions of the esophagus: a replacement for thoracoscopy?

ABSTRACT

Benign esophageal lesions are rare conditions and tumors account for about 10% of all esophageal neoplasms. Epiphrenic diverticula occur in the distal esophagus (the lower 10 cm). Currently, thoracotomy/thoracoscopy is the most popular approach for these conditions. We present our experience of 13 patients (1994-2006) with benign supra-diaphragmatic esophageal lesions that we treated with a laparoscopic transhiatal approach. The lesions included in the series were lower esophageal tumors (n = 8) and epiphrenic diverticula (n = 5). Laparoscopic transhiatal stapler excisions of diverticulum and enucleation of tumors were performed for all patients. Intra-operative endoscopy was used in all the procedures. All patients had an uneventful recovery except one with posterior diverticulum, who had an anastomotic leak. He had a prolonged hospital stay and recovered eventually. There was no mortality. Benign lesions of the lower third of the esophagus can be adequately treated through the transhiatal route. This is probably superior to the traditional approaches of thoracotomy/thoracoscopy as it does away with increased morbidity while maintaining adequate access. An endoscopy is of great value in localizing the lesion and assessing the esophageal lumen size during the application of staples. A laparoscopic transhiatal excision is technically feasible for all benign supra-diaphragmatic lesions and epiphrenic diverticula and is the approach of choice.
