Objective: Most researchers believe that the presence of large epiphrenic diverticulum (ED) with severe symptoms should lead to the consideration of surgical options. The choice of minimally invasive techniques and whether Heller myotomy with antireflux fundoplication should be employed after diverticulectomy became points of debate. The aim of this study was to describe how to perform laparoscopic transhiatal diverticulectomy (LTD) and oesophagomyotomy with the aid of intraoperative gastrointestinal (GI) endoscopy and how to investigate whether the oesophagomyotomy should be performed routinely after LTD. Patients and Methods: From 2008 to 2013, 11 patients with ED underwent LTD with the aid of intraoperative GI endoscopy at our department. Before surgery, 4 patients successfully underwent oesophageal manometry: Oesophageal dysfunction and an increase of the lower oesophageal sphincter pressure (LESP) were found in 2 patients. Results: There were 2 cases of conversion to an open transthoracic procedure. Six patients underwent LTD, Heller myotomy and Dor fundoplication; and 3 patients underwent only LTD. The dysphagia and regurgitation 11 patients experienced before surgery improved significantly. Motor function studies showed that there was no oesophageal peristalsis in 5 patients during follow-up, while 6 patients showed seemingly normal oesophageal motility. The LESP of 6 patients undergoing LTD, myotomy and Dor fundoplication was 16.7 ± 10.2 mmHg, while the LESPs of 3 patients undergoing only LTD were 26 mmHg, 18 mmHg and 21 mmHg, respectively. In 4 cases experiencing LTD, myotomy and Dor fundoplication, the gastro-oesophageal reflux occurred during the sleep stage. Conclusions: LTD constitutes a safe and valid approach for ED patients with severe symptoms. As not all patients with large ED have oesophageal disorders, according to manometric and endoscopic results, surgeons can categorise and decide whether or not myotomy and antireflux surgery after LTD will be conducted.
