Peroral Endoscopic Myotomy for Achalasia after Bariatric Surgery: A Case Report and Review of the Literature. Diagnostics (Basel) 2023; 13:3311. [PMID: 37958207 PMCID: PMC10647658 DOI: 10.3390/diagnostics13213311] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Revised: 10/07/2023] [Accepted: 10/18/2023] [Indexed: 11/15/2023] Open
Abstract
INTRODUCTION Achalasia following bariatric surgery is a rare phenomenon with diverse potential physiopathological origins. AIMS This article aims to explore the hypothetical physiopathological connection between bariatric surgery and the subsequent onset of achalasia. MATERIAL AND METHODS A review was conducted to identify studies reporting cases of peroral endoscopic myotomy (POEM) after bariatric procedures and detailing the outcomes in terms of the technical and clinical success. Additionally, a case of a successful POEM performed on a patient two years after undergoing laparoscopic sleeve gastrectomy (LSG) is presented. RESULTS The selection criteria yielded eight studies encompassing 40 patients treated with POEM for achalasia after bariatric surgery: 34 after Roux-en-Y gastric bypass (RYGB) and 6 after LSG. The studies reported an overall technical success rate of 97.5%, with clinical success achieved in 85% of cases. Adverse events were minimal, with only one case of esophageal leak treated endoscopically. However, a postprocedural symptomatic evaluation was notably lacking in most of the included studies. CONCLUSIONS Achalasia poses a considerable challenge within the bariatric surgery population. POEM has emerged as a technically viable and safe intervention for this patient demographic, providing an effective treatment option where surgical alternatives for achalasia are limited. Our findings highlight the promising outcomes of POEM in these patients, but the existing data remain limited. Hence, prospective studies are needed to elucidate the optimal pre-surgical assessment and timing of endoscopic procedures for optimizing outcomes.

Abstract
PURPOSE Synchronous and metachronous presentations of achalasia and obesity are increasingly common. There is limited data to guide the combined or staged surgical approaches to these conditions. METHODS A systematic review (MEDLINE, Embase, and Web of Science) and patient-level meta-analysis of published cases were performed to examine the most effective surgical approach for patients with synchronous or metachronous presentations of achalasia and obesity. RESULTS Thirty-three studies with 93 patients were reviewed. Eighteen patients underwent concurrent achalasia and bariatric surgery, with the most common (n = 12, 72.2%) being laparoscopic Heller's myotomy (LHM) and Roux-en-Y gastric bypass (RYGB). This combination achieved 68.9% excess weight loss and 100% remission of achalasia (mean follow-up: 3 years). Seven (6 RYGB, 1 biliopancreatic diversion) patients had bariatric surgery following achalasia surgery. Of these, all 6 RYGBs had satisfactory bariatric outcomes, with complete remission of their achalasia (mean follow-up: 1.8 years). Sixty-eight patients underwent myotomy following bariatric surgery; the majority (n = 55, 80.9%) were following RYGB. In this scenario, per-oral endoscopic myotomy (POEM) achieved higher treatment success than LHM (n = 33 of 35, 94.3% vs. n = 14 of 20, 70.0%, p = 0.021). Moreover, conversion to RYGB following a restrictive bariatric procedure during achalasia surgery was also associated with higher achalasia treatment success. CONCLUSION In patients with concurrent achalasia and obesity, LHM and RYGB achieved good outcomes for both pathologies. For those with weight gain post-achalasia surgery, RYGB provided satisfactory weight loss, without adversely affecting achalasia symptoms. For those with achalasia after bariatric surgery, POEM and conversion to RYGB produced greater treatment success.

Efficacy of peroral endoscopic myotomy for esophageal motility disorders after gastric surgery: Japan Achalasia Multicenter Study. Dig Endosc 2022; 34:1394-1402.

Abstract
OBJECTIVES Patients with esophageal motility disorders (EMDs) including achalasia after gastric surgery have not been thoroughly characterized. Furthermore, the efficacy of peroral endoscopic myotomy (POEM) in this population should be clarified. METHODS In this retrospective multicenter study of 3707 patients with EMDs, 31 patients (0.8%) had a history of gastric surgery. Patient characteristics and POEM efficacy were compared between patients with and without previous gastric surgery. RESULTS In patients with EMD after gastric surgery, age at EMD diagnosis was higher (72.0 years), male sex was predominant (90.3%), and the American Society of Anesthesiologists physical status score was higher (≥II, 48.4%). High-resolution manometry (HRM) findings did not reveal significant differences. In patients who underwent gastric surgery, atrophic gastritis was common (80.6%), and gastric cancer was the primary surgical indication (32.3%). Distal gastrectomy was performed in 28 patients (90.3%). POEM was effective (3.3% adverse events; 100% treatment success). The incidence rates of reflux esophagitis (RE) and symptomatic gastroesophageal reflux disease (GERD) were 60.0% and 16.7%, respectively, without significant intergroup differences, and severe RE was not observed in the long-term follow-up. Extended gastric myotomy was a risk factor for RE. CONCLUSION Patients with gastric surgery often present severe disease manifestations; the surgical indication is mainly gastric cancer. HRM findings can be similarly used for diagnosis in patients with and without gastric surgery. POEM maintains safety and efficacy with acceptable RE and symptomatic GERD rates. To prevent RE, extended myotomy should be avoided.

Outcomes of peroral endoscopic myotomy in patients with achalasia and prior bariatric surgery: A multicenter experience. Dis Esophagus 2021; 34:6310824. [PMID: 34184036 DOI: 10.1093/dote/doab044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2021] [Revised: 06/02/2021] [Accepted: 06/12/2021] [Indexed: 12/11/2022]
Abstract
Peroral endoscopic myotomy (POEM) in patients with achalasia who are status post bariatric surgery may be technically challenging due to postsurgical scarring and altered anatomy. The aim of the study was to assess the efficacy and safety of POEM for achalasia in patients with prior bariatric surgery. A review of prospectively maintained databases at three tertiary referral centers from January 2015 to January 2021 was performed. The primary outcome of interest was clinical success, defined as a post-treatment Eckardt score ≤ 3 or improvement in Eckardt score by ≥ 1 when the baseline score was <3, and improvement of symptoms. Secondary outcomes were adverse event rates and symptom recurrence. Sixteen patients status post Roux-en-Y gastric bypass (n = 14) and sleeve gastrectomy (n = 2) met inclusion criteria. Indications for POEM were achalasia type I (n = 2), type II (n = 9), and type III (n = 5). POEM was performed either by anterior or posterior approach. The pre-POEM mean integrated relaxation pressure was 26.2 ± 7.6 mm Hg. The mean total myotomy length was 10.2 ± 2.7 cm. The mean length of hospitalization was 1.4 ± 0.7 days. Pre- and postprocedure Eckardt scores were 6.1 ± 2.1 and 1.7 ± 1.8, respectively. The overall clinical success rate was 93.8% (15/16) with mean follow-up duration of 15.5 months. One patient had esophageal leak on postprocedure esophagram and managed endoscopically. Dysphagia recurred in two patients, which was successfully managed with pneumatic dilation with or without botulinum toxin injection. POEM appears to be safe and effective in the management of patients with achalasia who have undergone prior bariatric surgery.

Abstract
BACKGROUND Per-oral endoscopic myotomy (POEM) is safe and effective for the treatment of achalasia. There is limited data on performance of POEM in patients with altered upper gastrointestinal anatomy, especially after bariatric surgery. Outcomes in patients with prior sleeve gastrectomy have not been reported.
AIM To assess the efficacy and safety of POEM in patients with prior bariatric surgery.
METHODS A prospective POEM database was reviewed from 3/2017-5/2020 to identify patients who underwent POEM after prior bariatric surgery. Efficacy was assessed by technical success (defined as the ability to successfully complete the procedure) and clinical success [decrease in Eckardt score (ES) to ≤ 3 post procedure]. Safety was evaluated by recording adverse events.
RESULTS Six patients (50% male, mean age 48 years) with a history of prior bariatric surgery who underwent POEM were included. Three had prior sleeve gastrectomy (SG) and three prior Roux-en-Y gastric bypass (RYGB). Four patients had achalasia subtype II and 2 had type I. Most (4) patients had undergone previous achalasia therapy. Technical success was 100%. Clinical success was achieved in 4 (67%) patients at mean follow-up of 21 mo. In one of the clinical failures, EndoFLIP evaluation demonstrated adequate treatment and candida esophagitis was noted as the likely cause of dysphagia. There were no major adverse events.
CONCLUSION POEM is technically feasible after both RYGB and SG and offers an effective treatment for this rare group of patients where surgical options for achalasia are limited.

Abstract
Achalasia is a rare esophageal motility disorder characterized by esophageal aperistalsis and impaired relaxation of lower esophageal sphincter. There is no cure for achalasia and all the current treatments are aimed at palliation of symptoms by reducing the lower esophageal sphincter pressure. Currently, laparoscopic Heller myotomy (LHM) with partial fundoplication is considered the most effective and durable treatment option owing to its superiority over other treatments such as pneumatic dilation. Advancements in interventional endoscopy led to a novel minimally invasive endoscopic alternative to LHM, namely peroral endoscopic myotomy (POEM). In the last decade since its inception, POEM expanded rapidly throughout the world due to excellent safety profile and its efficacy comparable to LHM. The main drawback of POEM is gastroesophageal reflux disease since it is not combined with an anti-reflux procedure. The current review focuses on the indications, contraindications, technique, outcomes of POEM in various patient populations, and complications along with its effectiveness in comparison to LHM and pneumatic dilation.

Abstract
BACKGROUND Although the link between achalasia and morbid obesity is unclear, the reported prevalence is 0.5-1% in this population. For bariatric surgery patients, optimal type and timing of achalasia intervention is uncertain. METHODS Patient charts from a single academic institution were retrospectively reviewed. Between 2012 and 2019, 245 patients were diagnosed with achalasia, 13 of whom underwent bariatric surgery and were included. Patients were divided into two groups depending on the timing of their achalasia diagnosis and bariatric surgery. Groups were compared in terms of type and timing of intervention as well as treatment response. RESULTS Group 1 included 4 patients diagnosed with achalasia before bariatric surgery. Three had laparoscopic Heller myotomy (LHM) and 1 had a per oral endoscopic myotomy (POEM). These patients had laparoscopic gastric bypass (LGB) within 5 years of achalasia diagnosis. Postoperatively, 1 had severe reflux with regurgitation necessitating radiofrequency energy application to the lower esophageal sphincter. All had relief from dysphagia. Group 2 included 9 patients diagnosed with achalasia after bariatric surgery. Achalasia subtypes were evenly distributed. Initial operations were: 5 LGB, 2 laparoscopic sleeve gastrectomy (LSG), 1 duodenal switch (DS), 1 lap band. One LSG patient was converted to LGB concurrently with LHM. On average, achalasia was diagnosed 8.3 years after bariatric surgery. Achalasia interventions included: 1 pneumatic dilation, 1 Botox injection, 1 POEM, 6 LHM. While LHM was the most common procedure, 4 of 6 patients experienced recurrent dysphagia, one of whom required esophagectomy. CONCLUSIONS Achalasia is a challenging problem in the bariatric surgery population. Recurrent symptoms are common. Patients treated for achalasia after bariatric surgery tended to have worse symptom resolution than those diagnosed prior to bariatric surgery. Additional prospective studies are needed to elucidate whether interventions for achalasia should be performed concurrently or in a particular sequence for optimal results.

Abstract
Achalasia is a type of esophageal motility disorder, consisting of relaxation dysfunction of the lower esophagus and disturbed esophageal peristalsis. Related clinical symptoms include dysphagia, regurgitation, chest pain, and weight loss. Traditional treatment options include endoscopic botulinum toxin injection, endoscopic pneumatic dilation, and laparoscopic Heller’s myotomy. These therapies mainly relieve symptoms by reducing the pressure on the lower esophageal sphincter and reducing blood flow resistance at the esophagogastric junction. Based on endoscopic submucosal dissection and natural orifice transluminal endoscopic surgery, peroral endoscopic myotomy (POEM) is a purely endoscopic method of myotomy with minimal invasiveness and a low rate of adverse events when performed by experienced operators. Since then, numerous studies have shown the significant clinical efficacy and safety of POEM. The purpose of this article is to introduce different modified POEMs, special indications for different POEMs, and their advantages as well as disadvantages.

Abstract
The development of achalasia in patients with a prior Roux-en-Y gastric bypass (RYGB) is rare and it often remains unclear whether the esophageal motility disorder is a pre-existing condition in the obese patient or develops de novo after the procedure. The aim of this study was to review the available evidence regarding the management of patients with achalasia after a RYGB. Intra-sphincteric injection of botulinum toxin and pneumatic dilatation can be used to eliminate the functional obstruction at the level of the gastroesophageal junction. However, considering that achalasia patients after RYGB are often young and these treatment modalities have shown worse long-term outcomes, endoscopic or surgical myotomy is preferred. Per-oral endoscopic myotomy (POEM) is a very effective first line of treatment, and as RYGB is an excellent anti-reflux operation per se, post-POEM reflux may not be an issue in these patients. Laparoscopic Heller myotomy (LHM) is also an effective and safe therapy in achalasia patients with RYGB anatomy, and the gastric remnant can be safely used to perform a fundoplication to cover the myotomy. LHM and POEM are both acceptable primary treatment modalities in this setting. Further studies are needed to elucidate the pathophysiology and optimal management of patients with achalasia after RYGB.
