Background and Aims

Partial fundoplication is commonly performed in conjunction with Heller Myotomy. It is, however, controversial whether anterior Dor or posterior Toupet partial fundoplication is the antireflux procedure of choice. The aim was to perform a systematic review and meta-analysis of studies comparing these two procedures.

Material and Methods

A search of PubMed, Cochrane database, Medline, Embase, Science Citation Index, Google scholar and current contents for English language articles comparing Dor and Toupet fundoplication following HM between 1991 and 2018 was performed. The outcome variables analyzed included operating time, length of hospital stay (LOHS), overall complication rate, quality of life (QOL), postoperative reflux, residual postoperative dysphagia, treatment failure and reoperations. The meta-analysis was prepared in accordance with the PRISMA-P statement.


Seven studies totaling 486 patients (Dor = 245, Toupet = 241) were analyzed. LOHS was significantly shorter for Toupet repair compared to Dor procedure (WMD 0.73, 95% CI 0.47 to 0.99; P < 0.0001). Furthermore, patients after Toupet experienced significantly better QOL than those after Dor (WMD 1.68, 95% CI 0.68 to 2.73, P < 0.001). All other variables showed comparable effects for these two procedures.


Our systematic review and meta-analysis revealed that Toupet fundoplication is superior to Dor in terms of LOHS and QOL following HM. For other variables such as postoperative reflux, postoperative dysphagia, complication rates and treatment failure, both Dor and Toupet fundoplication produced effective and equivalent results.
