Background/Aims

Laparoscopic Heller myotomy with antireflux procedure is considered to be a standard treatment for achalasia. Recently, peroral endoscopic myotomy (POEM) was developed and performed on patients with achalasia. However, there is no report on POEM use in South Korea. The aim of this study was to evaluate the technical feasibility of POEM in a porcine model.

Methods

POEM was performed on two mini pigs. We performed upper endoscopy under general anesthesia. A submucosal tunnel was created and the circular muscle layer was incised using several knives. The mucosal entry was closed using resolution clips. We performed a follow-up endoscopy and sacrificed the pigs 2 weeks after the POEM. The myotomy site was evaluated grossly and histologically.

Results

POEM was successfully performed on the two mini pigs. No injuries to any abdominal or mediastinal structures occurred. Two weeks after the POEM, the esophageal mucosa healed without any endoscopic evidence of complications. Necropsy revealed that the circular muscle layer was completely lost and replaced with fibrotic tissue.

Conclusions

We found that POEM is a technically feasible method which can be performed on an animal model. However, to ensure safe use on patients with achalasia, further studies on technical methods and long-term follow-up examinations are required.

AbstractAbstract PDFPubReaderePub

Endoscopic submucosal dissection is a technically challenging but highly effective technique for the treatment of well selected early neoplasms in the digestive tract. Although it is frequently performed in East Asian countries, the Western world has not adopted this technique yet, probably due in part to the difficulty to learn it. Ex vivo and in vivo animal models are invaluable tools to overcome at least the beginning of the learning curve, although the initial step is the acquisition of basic knowledge about early diagnosis of neoplasias, and observing real procedures in expert centers. The practical issues, advantages, and disadvantages of the ex vivo and in vivo models are discussed.

AbstractAbstract PDFPubReaderePub

Introduction of endoscopic submucosal dissection (ESD) has brought about a renaissance in therapeutic endoscopy. For the globalization and universalization of ESD, the number of physicians who can perform ESD has rapidly increased with general ex vivo and in vivo training using animal models and hand-on courses. In this focused review series, world-renowned ESD experts described the published studies or their own precious experiences about ESD training and performing ESD with accurate and safe techniques. First, Dr. Adolfo Parra-Blanco reviewed on ex vivo and in vivo models for ESD training. Next, Dr. Joo Young Cho described detailed practical settings and current status of hands-on courses using ex vivo and in vivo models in Korea. Dr. Takashi Toyonaga described quality controlled ESD and basic techniques to prevent complications. Dr. Tsuneo Oyama reviewed recently published methods to facilitate ESD. Dr. Jae-Young Jang reviewed the usefulness of magnifying and narrow band imaging to measure the depth of invasion before ESD.
