Peroral endoscopic myotomy (POEM) is a minimally invasive therapeutic approach requiring tailored anesthetic management. This study aimed to evaluate perioperative anesthesia management during POEM, focusing on ventilation parameters, intraoperative hemodynamics, laboratory changes, and the incidence and severity of postoperative complications. Methods: A retrospective analysis was conducted on 51 patients who underwent POEM between June 2016 and April 2025. Demographic features, anesthesia techniques, intraoperative physiologic parameters, hematologic profiles, and postoperative complications were evaluated. Standard preoperative fasting protocols were implemented. Rapid sequence induction (RSI) with propofol and rocuronium was followed by endotracheal intubation. Desflurane was used for maintenance anesthesia, with ventilation settings adjusted to limit end-tidal carbon dioxide (ETCO2) elevation. Results: The median age of patients was 48 years, with a slight female (52.9%) predominance. Most patients were American Society of Anesthesiologists (ASA) II (64.7%) or ASA III (35.3%) scores and had comorbid hypertension (31.4%) or diabetes (11.8%). The median anesthesia duration was 180 min, and the peak inspiratory pressure remained stable at 25 mmHg. Oxygen saturation (SpO2) improved during the procedure, while ETCO2 increased from baseline to 49 mmHg by the end. Blood pressure declined transiently but recovered intraoperatively. Hematologic analysis showed significant increases in white blood cell (WBC) and neutrophils and mild decreases in hemoglobin, hematocrit, and platelets. Early postoperative complications included subcutaneous emphysema (19.6%), minor bleeding (9.8%), and pneumoperitoneum (7.84%). Two patients required tube thoracostomy due to pneumothorax, but no patient developed a complication requiring surgical exploration. During a median follow-up of 546 days, no mortality was reported. Long-term complications were infrequent, with gastroesophageal reflux disease (GERD) (3.92%) and esophagitis (1.96%) being the most notable. Conclusions: POEM can be performed safely with appropriate anesthetic management. Despite significant physiologic changes during carbon dioxide (CO2) insufflation, no life-threatening complications occurred, and the majority of adverse events were minor and self-limiting. Close intraoperative monitoring and interdisciplinary coordination contribute to favorable perioperative outcomes.<\/jats:p>","DOI":"10.3390\/jcm14186504","type":"journal-article","created":{"date-parts":[[2025,9,16]],"date-time":"2025-09-16T07:33:02Z","timestamp":1758007982000},"page":"6504","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Evaluation of Anesthesia Management During Peroral Endoscopic Myotomy in Patients with Achalasia: A Retrospective Study"],"prefix":"10.3390","volume":"14","author":[{"given":"Mukadder","family":"Sanli","sequence":"first","affiliation":[{"name":"Department of Anesthesiology and Reanimation, Inonu University Faculty of Medicine, 44280 Malatya, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6864-7711","authenticated-orcid":false,"given":"Sami","family":"Akbulut","sequence":"additional","affiliation":[{"name":"Department of Surgery, Inonu University Faculty of Medicine, 44280 Malatya, Turkey"},{"name":"Liver Transplant Institute, Inonu University Faculty of Medicine, 44280 Malatya, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1232-9829","authenticated-orcid":false,"given":"Muharrem","family":"Ucar","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology and Reanimation, Inonu University Faculty of Medicine, 44280 Malatya, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yilmaz","family":"Bilgic","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Inonu University Faculty of Medicine, 44280 Malatya, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,9,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1516","DOI":"10.1007\/s00268-022-06483-3","article-title":"Esophageal Achalasia: Diagnostic Evaluation","volume":"46","author":"Riccio","year":"2022","journal-title":"World J.
