PRospective Registry of Esophageal Motility

Digestive physiopathology is a branch of gastroenterology aiming to study patients with upper GI symptoms, mainly gastro-esophageal, potentially indicating the presence of Gastroesophageal Reflux Disease (GERD)/Barrett Esophagus (BE) or obstructive esophageal motility disorders (achalasia being the most relevant), but including also other primary motility disorders such as Esophgago-Gastric Junction Outflow Obstruction (EGJOO), Hypercontractile Esophagus (HE), Distal Esophageal Spasm (DES) and other minor disorders. Physiopathological testing encompasses High-Resolution Manometry (HRM), 24-H esophageal pH-impedance testing, Functional Lumen Imaging Probe (FLIP) assessment. All these tests are designed to provide a clear phenotyping of esophago-gastric disorders related to reflux or obstructive esophageal symptoms, either in naïve patients, as well as after foregut surgery (particularly anti-reflux surgery, achalasia/primary motility disorders treatment).

Clinical Utility of WATS3D: A 5-Year Prospective Study

The purpose of this study is to create a registry (collect data and keep it in a research database) to learn more about two methods of taking small tissue samples from your esophagus (the esophagus is the tube that carries food and liquid from your mouth to your stomach). The two methods of sampling are: 1) Using forceps that take biopsies (small tissue samples) from your esophagus, and 2) Using a brush that also takes biopsies from your esophagus.

Safety and Feasibility Study of the CELLSPAN Esophageal Implant (CEI) in Patients Requiring Short Segment Esophageal Replacement

Cellspan™ Esophageal Implant-Adult (CEI) The CEI is a combination product consisting of an engineered synthetic scaffold (device constituent) seeded and cultured with the patient's adipose derived mesenchymal stem cells (biologic constituent), intended to stimulate regeneration of a structurally intact, living biologic esophageal conduit, in patients requiring full circumferential esophageal reconstruction up to 6 cm segment in length. This is a dual arm, unblinded, multicenter, prospective first-in-human (FIH) feasibility study to be performed at a maximum of 5 centers in the United States with a maximum of 10 subjects in total. All subjects will be followed for a minimum of 2 years post-implant surgery. Since this is an FIH experience, the study will utilize an independent Data Monitoring Committee (DMC) to evaluate safety on a continuous basis to mitigate any safety risks to subjects. A sentinel approach to enrollment of subjects shall be guided by the DMC review of cases.

Effectiveness of Methods for Pyloric Drainage in esophagecTomY: Botox vs. Pyloromyotomy

The goal of this pragmatic, registry-based, randomized clinical trial is to find out if using botulinum toxin (Botox) to help drain the stomach during an esophagectomy works as well as a pyloromyotomy in patients undergoing elective esophagectomy for benign or malignant esophageal disease. Both methods are intended to prevent problems with food emptying too slowly from the stomach (delayed gastric emptying), which can cause discomfort after surgery. The main question it aims to answer is: Is intrapyloric Botox injection as a drainage procedure during esophagectomy non-inferior in preventing symptoms of delayed gastric emptying at 6 months postoperatively compared to pyloromyotomy? Researchers will compare intrapyloric Botox injection to pyloromyotomy to see if Botox is non-inferior to pyloromyotomy in easing symptoms of delayed gastric emptying. Participants will: Be randomized to one of two treatment groups-either intrapyloric Botox injection or pyloromyotomy-during their esophagectomy. Complete surveys assessing digestive symptoms at standard postoperative follow-up intervals (3 months, 6 months, 1 year, and 2 years postoperatively). Undergo a standard gastric emptying study at 6 months after surgery.

Comparison of Conventional and Short Submucosal Tunnel Techniques in Type II Achalasia

Rationale for This Study The primary rationale for this study is to evaluate whether a shorter submucosal tunnel during POEM with an EGJ-focused myotomy in type II Achalasia cardia patients, provides equivalent or superior symptom relief compared to the conventional approach while minimizing adverse events such as GERD \& blown out myotomy and decreasing the procedure time. Objectives Primary Objective: To compare the incidence of GERD (with manual review) at 3 and 12 months' post-procedure between conventional POEM and two experimental short-tunnel POEM techniques in patients with Type II achalasia. Secondary Objectives: To evaluate 1. Clinical success based on Eckardt score 2. Operating total procedure time 3. Use of Acid Suppressants on Follow up at 1 year 4. Severity of Esophagitis at 3 months 5. Intraoperative \& Postoperative adverse events (AGREE classification), 6. GERD-HRQL (0-18) scores 3 \& 12 Months 7. (Clinically relevant GORD was defined as excessive oesophageal /AET associated with a GERDQ score \>7 and/or with any grade of reflux oesophagitis). 8. Duration of Hospital stay 9. Quality of life (SF36)

Esophageal and Gastric Diseases With Robotically Controlled Magnetic Capsule Endoscopy

Magnetically controlled capsule endoscopy (MCCE) is an outstanding opportunity for the painless endoscopic screening of the esophagus and stomach before small bowel examiantion. Further improvement in patients positioning might increase the esophageal transit time of the capsule endoscope and could improve the sensitivity and specificity of the esophageal MCCE investigation. Our present study aimed to compare the visualization of the esophagus (especially the Z-line) with different capsule swallowing protocols.

Standard Versus Oesophago-gastric Junction Complex Myotomy for Treatment naïve Type 2 Achalasia Patients

\- Consecutive eligible patients will be randomized in a 1:1 ratio to esophagogastric complex only myotomy or standard myotomy groups. Randomization is done according to the computer-generated algorithm. A clinical research coordinator will prepare the sealed randomization envelops and will hand over to the operating endoscopists before the beginning of the procedure. Written informed consent will be obtained from all participants. In this study, the participants and the care-provider assessing the clinical response to the POEM procedure at 3months will be blinded to the allocation.

Seattle Spatial Transcriptomic Research in Inflammatory Bowel Disease Evaluation (STRIDE)

This is a prospective observational study collecting long-term clinical data and samples for research in pediatric inflammatory bowel disease (IBD) patients with gut inflammation and a control cohort of pediatric patients with disorders of the brain-gut interactions (DBGI) with no detectable gut inflammation.

Esophageal Cancer Risk Registry

The purpose of this study is to identify markers in the blood and tissue that could indicate risk factors for the development and progression of esophagus cancer. This research aims to collect medical history, blood, and tissue samples from patients who present with an esophageal disorder. Identifying genetic and behavioral risk factors involved in the development of esophageal cancer might allow for early detection and prevention. Survival and an opportunity for a cure with esophageal cancer will depend greatly on the stage of diagnosis. Tumors can develop changes in their genetic (hereditary) make-up, and these changes can sometimes be seen in normal tissues before the development of cancer. These genetic (hereditary) changes can serve as tumor markers and can be detected using methods that study changes in genetic material like DNA and RNA. The analysis of proteins can provide additional information. By identifying changes in these molecules that are different or altered in cancer, the investigators can use methods and tests for the detection of these changes.

Comparative Assessment of Esophagitis in Cases With and Without Esophageal Motility Disorders: A Prospective Study

Achalasia is a neuro-degenerative disorder marked by changes in the peristalsis of the esophagus and the lack of relaxation in the lower esophageal sphincter (LES), thought to be due to damage to the myenteric plexus with an unknown cause.1 Per-oral endoscopic myotomy (POEM) is an established endoscopic treatment modality for achalasia. Leading gastrointestinal (GI) societies endorse POEM as one of the primary treatment option for achalasia.This study aims to characterize and compare the morphological characteristics of reflux related erosions after the POEM procedures versus those in cases without esophageal motility disorders. Data collection 1. Demographic characteristics: Age, gender, type of achalasia 2. Manometry findings (pre and post POEM): integrated relaxation pressure, lower esophageal sphincter pressure 3. Comorbidities 4. Medications 5. Eckardt score: before procedure and 3-months after Procedure 6. POEM procedure details: length of esophageal and gastric myotomy, adverse events, length of hospital stay 7. Evaluation at 3-months Symptom: standardized questionnaire (GERDQ) Endoscopy: grade of esophagitis Erosions vs ulcers Dimension of erosions Anatomical location (according to clock)
