Project description:Esophageal diverticula (ED) represents a group of rare conditions that warrant intervention when they are symptomatic or coexisting with pulmonary disorders. Few literature reviews have described this patient entity or discussed the postoperative outcome. Therefore, I present the case of a 59-year-old woman with symptoms of dysphagia who was significantly underweight, which was conducive to the diagnosis of symptomatic ED. Because she was a poor candidate for surgery, she received a diverticular peroral endoscopic myotomy. She subsequently developed parapneumonic effusion and tension pneumothorax after the procedure. She was finally discharged on postoperative day 23. I also performed the first known comprehensive literature review of 34 published cases (including my patient) from PubMed and have addressed the demography, intervention, and prognosis for symptomatic ED after the procedure. Prompt treatment as well as prognostic measurement are crucial to successful outcomes.

Two-Stage Peroral Endoscopic Myotomy for Sigmoid-Type Achalasia.

Project description:Peroral endoscopic myotomy (POEM) has been recently considered as the first treatment option for achalasia. The standard POEM procedures are often successful in most patients, but sometimes technical challenges are encountered. We report a new technique that is divided between two tunneling sites in the esophagus for sigmoid-type achalasia. A 40-year-old male patient with dysphagia for 10 years was diagnosed with a sigmoid-shaped esophagus at our hospital. We devised a two-stage myotomy technique to treat sigmoidtype achalasia. The myotomy was first performed in the upper part of the greater flexion area and then in the lower part of the flexion. We termed this method "two-stage POEM", which was successfully performed without any complications. This new POEM method can also be used to improve symptoms in patients with achalasia who have a structural deformity that may result in a high change of treatment failure.

Hybrid Peroral Endoscopic Myotomy for Achalasia with Prior Treatment Failure.

Project description:Achalasia is a neurodegenerative motility disorder caused by enteric neuron damage in the lower esophageal sphincter. Peroral endoscopic myotomy (POEM) is a standard treatment method for achalasia. Previous treatment modalities may affect the outcome of POEM as they cause submucosal fibrosis. We report a new technique called "hybrid POEM" for the treatment of patients with achalasia who had been previously treated with pneumatic balloon dilatation. We performed two techniques of POEM simultaneously, the standard POEM for the upper part of the submucosal tunnel and open POEM for the stenotic part of the esophagogastric junction. We dissected the mucosa and submucosa, and performed myotomy simultaneously. We overcame submucosal fibrosis of the esophagogastric junction, which was caused by the previous hybrid POEM treatment. The risks of mucosal incision and technical challenge of submucosal tunneling for the fibrotic area may be reduced by hybrid POEM.

Blown-out myotomy: an adverse event of laparoscopic Heller myotomy and peroral endoscopic myotomy for achalasia.

Project description:Background and aimsAlthough laparoscopic Heller myotomy (LHM) or peroral endoscopic myotomy (POEM) is highly effective, 10% to 20% of patients with achalasia remain symptomatic after treatment. In evaluating such patients, we have observed a pattern of failure associated with a pseudodiverticulum, or blown-out myotomy (BOM), in the distal esophagus. We aimed to assess risk factors and patient-reported outcomes associated with a BOM.MethodsWe reviewed our manometry database for patients with achalasia previously treated with LHM or POEM. We included patients who had a post-treatment esophagram within 1 year of their follow-up manometry. A BOM was defined radiographically as a wide-mouthed outpouching (>50% increase in esophageal diameter) in the area of the myotomy.ResultsOne hundred twenty-nine patients with achalasia who underwent treatment were included; 23 (17.8%) had a BOM. Comparing patients with a BOM with those without, post-treatment Eckardt scores were significantly greater (5 vs 2, P = .002), type III achalasia was more common (39.1% vs 14.2%, P = .005), and LHM was more common than POEM (73.9% vs 26.1%, P = .013). The integrated relaxation pressure was also significantly greater in the BOM group (15.0 mm Hg vs 11.0 mm Hg, P = .025).ConclusionsBOM is a common adverse event after myotomy for achalasia but is not seen after pneumatic dilation. Pretreatment type III achalasia, LHM as opposed to POEM, and a greater post-treatment integrated relaxation pressure were risk factors for developing a BOM. We speculate that esophageal wall strain in the area weakened by myotomy, whether from residual spastic contractility or continued esophageal outflow obstruction, may be the underlying mechanism of BOM development.
