Background: The functional lumen imaging probe is a balloon-based catheter that can be used as a bougie during fundoplication. Our goal was to compare the short-term, quality-of-life outcomes and esophageal-injury rate after fundoplication over a functional lumen imaging probe compared to a traditional bougie., Methods: This is a retrospective review of a quality database at a single center. Three-week and 6-month Reflux Symptom Index, Gastroesophageal Reflux Disease-health Related Quality of Life, and dysphagia scores were compared. The need for endoscopy and dilation between the groups was also compared., Results: Between 2008 and 2020, 423 fundoplications were performed over a bougie and 62 over the functional lumen imaging probe. Six months after surgery, the functional lumen imaging probe group reported significantly worse dysphagia scores (1.5 ± 1.0 vs 1.1 ± 0.3, P = .007), but rates of endoscopy (4.8% vs 5.0%, P = .966) and dilation (4.8% vs 3.8%, P = .723) were similar. There were no differences between Reflux Symptom Index and Gastroesophageal Reflux Disease-health Related Quality of Life scores. The rate of bougie-related injuries was 2.1% vs 0% for the functional lumen imaging probe group., Conclusion: Patients undergoing fundoplication over the functional lumen imaging probe had comparable short-term outcomes compared with those over a traditional bougie. The rate of esophageal injury while using the functional lumen imaging probe is lower than a bougie and may be preferable for fundoplication creation., (Copyright © 2020 Elsevier Inc.

Background: We provide a comprehensive report of our institution's experience with the endoluminal functional lumen imaging probe (Endoflip) impedance planimetry system, a device that can be used intraoperatively to objectively evaluate the distensibility of any sphincter of the gastrointestinal tract. We aim to describe the variety of ways in which the Endoflip can be used in a foregut surgeon's practice., Study Design: This is a retrospective review of a prospectively maintained quality database of all patients in which the functional lumen imaging probe (FLIP) system was used between February 2013 and June 2019., Results: During the study period, 402 FLIP cases were performed: 226 fundoplications, 94 peroral endoscopic myotomies, 15 peroral pyloromyotomies, 12 antireflux mucosectomies, 11 magnetic sphincter augmentations, 9 laparoscopic Heller myotomies, 8 pre-esophagectomy esophagogastroduodenoscopies (EGDs), 4 diagnostic EGDs, 8 endoscopic Zenker's diverticulotomies, 5 post-peroral endoscopic myotomy EGDs, 8 EGDs with dilations, and 2 transoral incisional fundoplications., Conclusions: Within a foregut surgeon's practice, the FLIP can be used to measure the upper esophageal sphincter, lower esophageal sphincter, and pylorus in a variety of clinical scenarios and settings., (Copyright © 2020 American College of Surgeons.
