We were unable to find any prior report of the combination of Heller myotomy with anterior partial fundoplication(Dor) as the treatment for EGJOO. We herein report a case of EGJOO treated with laparoscopic Heller myotomy combined with Dor fundoplication.CASE SUMMARY A 26-year-old man presented with a 3-year history of solid dysphagia and a 30-kg weight loss. He was treated with oral nifedipine, isosorbide, and omeprazole,without resolution of symptoms. An upper gastrointestinal series(barium swallow) revealed a "bird's beak" sign. Esophagogastroduodenoscopy was positive for Los Angeles grade A peptic esophagitis. High-resolution esophageal manometry was compatible with EGJOO. Esophageal pH monitoring showed pathological acid reflux both in orthostatic and decubitus position. An 8-cm laparoscopic Heller myotomy combined with an anterior 220° Dor fundoplication was performed. Solid diet was introduced on postoperative day 2, and the patient was discharged home the same day. At 17-mo follow-up, he reported no symptoms. Barium swallow was compatible with complete radiologic resolution.Both esophageal manometry and upper endoscopy showed normal findings 9 mo after the operation.CONCLUSION Surgical treatment with Heller myotomy and Dor fundoplication is a potential treatment option for EGJOO refractory to medical treatment.展开更多

Consequently, several modifications of this method have been described, whereas laparoscopic fundoplication was recently introduced. Although single incision(SI) fundoplication was considered as an alternative to the conventional laparoscopic approach, several studies reported an increased operation duration, and high rates of multiport conversion and incisional hernia.AIM To provide a current overview of the technical variations and the postoperative outcomes of patients submitted to SI fundoplication.METHODS The present systematic review of the literature was designed and conducted on the basis of the PRISMA guidelines. A systematic screening of the electronic scholar databases(Medline, Scopus and Web of Science) was performed.RESULTS Literature search resulted in the identification of 19 studies. Overall, 266, 137 and110 SI Nissen, Dor and Toupet fundoplications were reported, respectively. In the majority of the trials, standard laparoscopic instruments were used. The left liver lobe was displayed through the use of forceps, graspers, retractors, drains or even glue. Both intra-corporeal and extracorporeal suturing was described. Mean operative time was 136.3 min. Overall complication rate was 5.2% and the rate of incisional hernia was 0.9%. No mortality was reported.CONCLUSIONDue to the methodological heterogeneity and the lack of high quality studies comparing multi to single access techniques and the several variations, we conclude that further well designed studies are necessary, in order to evaluate the role of SI fundoplication.展开更多
