Advanced megaesophagus predisposes to risks of malnutrition infections and cancer, in addition to having a significant impact on quality of life. There is currently no consensus in the literature regarding the best surgical option for advanced megaesophagus, although there is a predilection for esophagectomy, despite this surgery being associated with significant morbidity and mortality. Other surgical procedures, such as esophageal mucosectomy and Heller cardiomyotomy, have been proposed with good results.
To conduct a systematic review and meta-analysis of the literature on the surgical treatment of advanced megaesophagus.
Databases used included PubMed, Latin American and Caribbean Health Sciences Literature (Lilacs), Embase and Medical Literature Analysis and Retrieval System Online (MedLine), as well as reference research. Two reviewers selected the articles independently.
A total of 14 articles were chosen, which included 1,862 patients. The studies were divided into two groups: laparoscopic cardiomyotomy with fundoplication (213 patients) and major surgeries (1,649 patients). The studies yielded mostly good or excellent results regarding late outcomes in both groups. However, there was significant morbidity associated with the major surgeries group.
Laparoscopic Heller myotomy can be performed on patients with advanced megaesophagus, with lower rates of complications and mortality compared to major surgeries, with reservations regarding late outcomes results.
HEADINGS:
Achalasia is an esophageal motility disorder, with clinical presentation of dysphagia and regurgitation. This is a chronic condition with no cure. Current treatment options aim to reduce lower esophageal sphincter tone by pharmacological, endoscopic or surgical means, with the aim of improving patients’ symptoms. Peroral endoscopic myotomy (POEM) is an alternative endoscopic surgery to Heller cardiomyotomy, in which the procedure is performed orally, by endoscopy, offering efficacy comparable to surgical myotomy, with relative ease and minimal invasion, without external incisions.
To study the safety of POEM by analyzing its results, adverse events and perioperative complications and the main ways to overcome them, in addition to evaluating the effectiveness of the procedure and the short-term postoperative quality of life.
A qualitative and quantitative, observational and cross-sectional study that analyzed patients who underwent the POEM in a reference center, from December 2016 to December 2022, maintaining the technical standard of pre-, peri- and postoperative protocol.
A total of 94 patients were included in the study, and only three had postoperative complications. The average early postoperative Eckardt score was 0.93 and the late 1.40, with a mean improvement of 7.1 in early results and 6.63 in late results (p<0.05).
POEM can be reproduced with an excellent safety profile, significant relief of symptoms and improvement in esophageal emptying, and in quality of life.
