Item Evaluation of timed barium esophagram after per-oral endoscopic myotomy to predict clinical response(Thieme, 2021-11-12) DeWitt, John M.; Siwiec, Robert M.; Perkins, Anthony; Baik, Daniel; Kessler, William R.; Nowak, Thomas V.; Wo, John M.; James-Stevenson, Toyia; Mendez, Martha; Dickson, Destenee; Stainko, Sarah; Akisik, Fatih; Lappas, John; Al-Haddad, Mohammad A.; Medicine, School of MedicineBackground and study aims: The aim of this study was to evaluate whether timed barium esophagram within 24 hours post-per-oral endoscopic myotomy (POEM) (TBE-PP) could predict clinical outcomes. Patients and methods: This was a single-center retrospective study of prospectively collected data on consecutive patients with ≥ 6-month follow-up who underwent POEM followed by TBE-PP. Esophageal contrast retention 2 minutes after TBE-PP was assessed as Grade 1 (< 10 %), 2 (10 %-49 %), 3 (50 %-89 %) or 4 (> 90 %). Eckardt score, esophagogastroduodenoscopy (EGD), high-resolution manometry (HRM) and function lumen imaging probe (FLIP) of the esophagogastric junction (EGJ) were obtained at baseline. These tests along with pH testing of antisecretory therapy were repeated 6 and 24 months after POEM. Clinical response by Eckardt score ≤ 3, EGJ-distensibility index (EGJ-DI) > 2.8 mm 2 /mm Hg, and integrated relaxation pressure (IRP) < 15 mm Hg and incidence of gastroesophageal reflux disease (GERD) were compared by transit time. Results: Of 181 patients (58 % male, mean 53 ± 17 yr), TBE-PP was classified as Grade 1 in 122 (67.4 %), Grade 2 in 41 (22.7 %), Grade 3 in 14 (7.7 %) and Grade 4 in 4 (2.2 %). At 6 months, overall clinical response by ES (91.7 %), IRP (86.6 %), EGJ-DI (95.7 %) and the diagnosis of GERD (68.6 %) was similar between Grade 1 and Grade 2-4 TBE-PP. At 24 months, Grade 1 had a higher frequency of a normal IRP compared to Grades 2-4 (95.7 % vs. 60 %, P = 0.021) but overall response by ES (91.2 %), EGJ-DI (92.3 %) and the diagnosis of GERD (74.3 %) were similar. Conclusions: Contrast emptying rate by esophagram after POEM has limited utility to predict clinical response or risk of post-procedure GERD.Item Prevalence and Impact of Opioid Use in Patients Undergoing Peroral Endoscopic Myotomy(Elsevier, 2023-04) Jacobs, Chelsea C.; Al-Haddad, Mohammad; Stainko, Sarah; Perkins, Anthony; DeWitt, John M.; Medicine, School of MedicineBackground and Aims Chronic narcotic use may cause opioid-induced esophageal dysfunction (OIED) and associated type 3 achalasia, hypercontractile esophagus (HE), diffuse esophageal spasm (DES) and esophagogastric junction outflow obstruction (EGJOO). The frequency of opioid use and its impact on peroral endoscopic myotomy (POEM) in these patients is unknown. Methods Consecutive patients between 04/2017 and 09/2021 who underwent POEM for type III achalasia, EGJOO, DES, or HE with ≥6 months follow-up were identified. Baseline evaluation: EGD, high resolution esophageal manometry (HRM) and functional lumen impedance planimetry (FLIP) of the esophagogastric junction (EGJ). Eckardt scores (ES) were calculated at baseline and follow-up at 6-12 months post-POEM for opioid users and opioid non-users. Clinical response (CR) was defined as ES≤3, EGJ-distensibility index (DI)>2.8mm2/mmHg, maximum EGJ diameter (MxEGJD)>14mm and integrated relaxation pressure (IRP)<15mmHg. Opioid use prior to baseline HRM was assessed. Results 126 patients underwent POEM and 89 had ≥6 months follow-up. Daily opioid use was present in 18/89 (20%). Baseline demographics, FLIP metrics, IRP, distribution of motility disorders and POEM characteristics were similar between both groups. At 6-12 months after POEM, clinical response as well as frequency of GERD, esophagitis, and PPI use were similar between opioid users and non-users. Heartburn was more frequent in the opioid group (82.4% vs 38.6%, p=0.002). Conclusion In this single center study of 89 patients with type III achalasia, EGJOO, DES, or HE treated with POEM, daily opioid use was present in 20%. Response to POEM and post-POEM GERD were similar between opioid and non-opioid users.Item Symptom association for gastroesophageal reflux disease by PH monitoring after peroral endoscopic myotomy: GERD and symptoms after POEM(Wolters Kluwer, 2022-04) DeWitt, John; Kessler, William; Wo, John; Stainko, Sarah; Perkins, Anthony; Dickason, Destenee; Al-Haddad, Mohammad; Siwiec, Robert; Biostatistics, School of Public HealthIntroduction: There are limited data correlating symptoms with reflux episodes during pH studies after POEM. Methods: Consecutive patients who underwent POEM followed ≥6 months later by 48-hour ambulatory wireless pH testing off antisecretory therapy were identified. Reflux symptom association (RSA) was defined as SAP >95%. Results: The most frequent of symptoms of heartburn (47.2%), cough (45.1%) and chest pain (39.6%) were associated with a positive RSA (SAP >95%) in 20.9%, 17.1% and 19.4%, respectively. Discussion: There is poor correlation between reported symptoms and esophageal acid exposure during pH testing after POEM.
