RESUMEN
INTRODUCTION AND AIMS: At the Upper Gastrointestinal Tract Clinic of the Hospital General de Mexico, achalasia treatment has been standarized through strictly graduated cardiomyotomy. This procedure guarantees a complete myotomy for the satisfactory resolution of dysphagia, a characteristic symptom of achalasia. To ensure the inclusion of the entire lower esophageal sphincter, an 8cm Penrose drain is placed at the surgical site 6cm above the gastroesophageal junction and 2cm in a caudal direction, for accurate laparoscopic measuring. The aim of our study was to evaluate the results of this technique. MATERIALS AND METHODS: A descriptive, retrospective, longitudinal, and observational study was conducted on a cohort of patients diagnosed with achalasia at the Upper Gastrointestinal Tract Clinic of the Hospital General de México "Dr. Eduardo Liceaga". RESULTS: The study included 48 patients, 40 of whom had no prior surgical treatment and 8 that presented with recurrence. Forty-seven patients (97.9%) underwent a laparoscopic procedure and conversion to open surgery was required in 2 of them (4.25% conversion rate). Postoperative progression was satisfactory in all cases, with mean oral diet commencement at 52h and mean hospital stay of 5.7 days. No recurrence was registered during the mean follow-up period of 35.75 months and there were no deaths. CONCLUSIONS: Laparoscopic graduated (strictly measured) cardiomyotomy with anterior fundoplication is a reproducible, efficacious, and safe option for the surgical treatment of achalasia.
