Abstract
BACKGROUND: Peroral endoscopic myotomy with fundoplication (POEM-F) has garnered widespread attention since it tries to achieve an appropriate antireflux procedure during the same setting. The outcomes of POEM-F are currently unexplored. METHODS: Patients who underwent POEM-F at our center were retrospectively studied to assess its safety and early outcomes. RESULTS: Twenty patients [70% male; median age 32 years (range 25-41)], with a median symptom duration of 2.1 years (range 1.5-3.7) with achalasia were included. POEM-F procedure was completed in a median of 118 min (range 90-160), with 17/20 (85%) technical success. The median hospitalization was 4 days (range 2-7). Capnothorax (n = 3), resolved spontaneously (n = 2) in 4-6 h, while in one patient (n = 1) the endoscope inadvertently entered into the thoracic cavity for which prophylactic intercostal drain was required. Capnoperitoneum was seen in 17/17 (100%) patients who underwent fundoplication, subcutaneous emphysema in 8/17 (47%) patients. At 1-month follow-up endoscopy, 5/17 (29.4%) patients had loosening of the fundal wrap, 3/17 (17.6%) patients had ulceration in fundus and in gastroesophageal junction due to underlying hemoclips. At 3 months, loosening of the fundal wrap was seen in 7/17 (41.2%) patients. A 24-h pH-metry revealed abnormal esophageal acid exposure in 7/17 (41.2%) patients, while it was normal in those patients in whom the fundal wrap was maintained. 10/17 (58.8%) patients were off proton pump inhibitors. CONCLUSION: POEM-F is technically feasible with reasonable short term success. However, the durability, early success and safety of POEM-F need reassessment in long-term studies before being applied in clinical practice.
