ABSTRACT OBJECTIVES To review transabdominal esophagocardiomyotomy (surgical treatment of achalasia) of the esophagus and to compare outcomes of partial anterior vs partial posterior fundoplication. DATA SOURCES An electronic search was conducted among studies published between January 1976 and September 2011 using the keywords achalasia, myotomy, antireflux surgery, and fundoplication. STUDY SELECTION Prospective studies of transabdominal esophagocardiomyotomy were selected. DATA EXTRACTION Outcomes selected were recurrent or persistent postoperative dysphagia and an abnormal 24-hour pH test result. Studies were divided into the following 3 groups: myotomy only, myotomy with anterior fundoplication, and myotomy with posterior fundoplication. Studies were weighted by the number of patients and by the follow-up duration. Event rates were calculated using meta-regression of the log-odds with the inverse variance method. DATA SYNTHESIS Thirty-nine studies with a total of 2998 patients were identified. The odds of postoperative dysphagia were 0.06 (95% CI, 0.03-0.12) for myotomy only, 0.11 (95% CI, 0.09-0.14) for myotomy with anterior fundoplication, and 0.06 (95% CI, 0.04-0.08) for myotomy with posterior fundoplication. The odds of a postoperative abnormal 24-hour pH test result were 0.37 (95% CI, 0.12-1.08) for myotomy only, 0.16 (95% CI, 0.11-0.24) for myotomy with anterior fundoplication, and 0.18 (95% CI, 0.13-0.25) for myotomy with posterior fundoplication. The increased odds of postoperative dysphagia in the group undergoing myotomy with anterior fundoplication compared with the group undergoing myotomy with posterior fundoplication were statistically significant (P < .001). However, the incidence of a postoperative abnormal 24-hour pH test result was statistically similar. CONCLUSION Partial posterior fundoplication when combined with an esophagocardiomyotomy may be associated with significantly lower reintervention rates for postoperative dysphagia, while providing similar reflux control compared with partial anterior fundoplication.

    ABSTRACT: To compare symptomatic and objective outcomes between HM and POEM. The surgical gold standard for achalasia is laparoscopic Heller myotomy (HM) and partial fundoplication. Per-oral endoscopic myotomy (POEM) is a less invasive flexible endoscopic alternative. We compare their safety and efficacy. Data on consecutive HMs and POEMs for achalasia from 2007 to 2012 were collected. Primary outcomes: swallowing function-1 and 6 months after surgery. Secondary outcomes: operative time, complications, postoperative gastro-esophageal reflux disease (GERD). There were 101 patients: 64 HMs (42% Toupet and 58% Dor fundoplications) and 37 POEMs. Presenting symptoms were comparable. Median operative time (149 vs 120 min, P < 0.001) and mean hospitalization (2.2 vs 1.1 days, P < 0.0001) were significantly higher for HMs. Postoperative morbidity was comparable. One-month Eckardt scores were significantly better for POEMs (1.8 vs 0.8, P < 0.0001). At 6 months, both groups had sustained similar improvements in their Eckardt scores (1.7 vs 1.2, P = 0.1).Both groups had significant improvements in postmyotomy lower esophageal sphincter profiles. Postmyotomy resting pressures were higher for POEMs than for HMs (16 vs 7.1 mm Hg, P = 0.006). Postmyotomy relaxation pressures and distal esophageal contraction amplitudes were not significantly different between groups. Routine postoperative 24-hour pH testing was obtained in 48% Hellers and 76% POEMs. Postoperatively, 39% of POEMs and 32% of HM had abnormal acid exposure (P = 0.7). POEM is an endoscopic therapy for achalasia with a shorter hospitalization than HM. Patient symptoms and esophageal physiology are improved equally with both procedures. Postoperative esophageal acid exposure is the same for both. The POEM is comparable with laparoscopic HM for safe and effective treatment of achalasia.

    ABSTRACT: The optimal anti-reflux procedure after Heller cardiomyotomy for oesophageal achalasia remains unclear. The most commonly used procedure is the anterior partial fundoplication according to Dor, although during recent years the posterior counterpart (Toupet) has become popular.

    ABSTRACT: The type of anti-reflux procedure to be used as an adjunct to laparoscopic Heller's cardiomyotomy (LHCM) in Achalasia cardia is controversial. We compared Angle of His accentuation and Dor fundoplication in a randomized controlled trial. From May 2010 to October 2013, 62 patients undergoing LHCM were randomized to receive either Dor fundoplication (Dor group) or Angle of His accentuation (AOH group) as an anti-reflux procedure. Symptomatic outcome was evaluated using modified Mellow and Pinkas scale for dysphagia and modified DeMeester's score for regurgitation and heartburn. Achalasia-specific quality-of-life (QOL) questionnaire was used to assess quality of life. The primary outcome was symptomatic relief and the secondary outcome was postoperative heartburn. Statistical analysis was done using SPSS software. All the procedures were completed laparoscopically with no mortality. Morbidity was similar in the two groups (6.4 %). Median operative time was higher in Dor group (170 vs 130 min). At a median follow-up of 21 months relief of dysphagia, regurgitation, and heartburn was seen in 87, 90.3, and 90.3 % patients in Dor group versus 93.5, 96.7, and 77.4 % in AOH group patients with significant improvement in symptom scores. Improvement was similar in both groups with no statistically significant difference in the symptom scores (p = 0.48 for dysphagia, p = 0.37 for regurgitation, and p = 0.19 for heartburn). The QOL improved in both groups [62.3 to 12.3 (p = 0.02) in Dor group and 63.9-13 (p = 0.02) in AOH group] with no statistically significant difference between the two groups (p = 0.96). There was no statistically significant difference in the postoperative heartburn between the two groups (p = 0.19). Laparoscopic Heller's cardiomyotomy with either Angle of His accentuation or Dor fundoplication leads to similar improvement in symptoms and quality of life.
