BACKGROUND: POEM (Per Oral Endoscopic Myotomy) is rapidly becoming a valid option for surgical myotomy in achalasia patients. Several techniques to perform POEM are described, but all concentrate on the division of the circular muscle fibers in a proximal-to-distal fashion. Our aim is to present the distal-to-proximal, or the bottom-up technique using the Flush/Dual knife, which overcomes the disadvantages of the standard technique.
METHODS: A retrospective study on a prospectively maintained database was performed on all patients treated by POEM in our institution. Clinical presentation, operating time, adverse events, and outcomes were studied.
RESULTS: POEM was performed on 105 achalasia patients. The first 15 cases were performed using the standard technique and were compared to the next 90 cases performed using the bottom-up technique. The average preop Eckardt scores in the standard and bottom-up groups were 9.5 and 8.8, respectively, declining to 1.4 and 0.5, 3 months post myotomy (p < 0.001). The average procedure time was 111.2 min for the standard technique and 74.3 for the bottom-up technique. (p = 0.002). Perioperative adverse events included 14 instances of pneumoperitoneum, 3 tunnel leaks, and 4 patients with fever on postoperative day one. Pneumoperitoneum needing decompression and postoperative fever were more prevalent in the standard technique group.
CONCLUSIONS: As POEM is becoming more common for the treatment of achalasia, refinements of the technique and instruments used are valuable. We compared our experience of the standard technique to our bottom-up technique and found the latter to be equally effective as well as safer, faster, and easier. We, therefore, suggest considering performing POEM in this technique.
