As such, antireflux procedures should address both for optimal improvement of EGJ physiology.Ĭopyright © 2020 Wolters Kluwer Health, Inc. Diaphragmatic re-approximation had a higher percent contribution to distensibility (79% vs 21%), CSA (82% vs 18%), and HPZ (60% vs 40%) than sphincter augmentation.ĭynamic intraoperative monitoring demonstrates that diaphragmatic re-approximation and sub-diaphragmatic relocation has a greater effect on EGJ compliance than sphincter augmentation. Rasa Zarnegar affiliates with New York-presbyterian Hospital, cooperates with many other doctors and specialists in medical group Weill Medical College Of Cornell. Having more than 23 years of diverse experiences, especially in GENERAL SURGERY, Dr. After sphincter augmentation, DI decreased 0.14 mm2/mm Hg (95%-CI: -0.30, -0.04 P = 0.0005) and CSA decreased 5.0 mm2 (95%-CI: -10.0, 1.0 P = ), whereas HPZ length increased 0.5 cm (95%-CI: 0.50, 0.54 P < 0.0001). Rasa Zarnegar is a General Surgery Specialist in New York, New York. Patients underwent Nissen (45%), Toupet (44%), or LINX (11%). Data was acquired pre-repair, post-diaphragmatic re-approximation with sub-diaphragmatic EGJ relocation, and post-sphincter augmentation. Intraoperative EGJ measurements including distensibility index (DI), cross-sectional area (CSA), and HPZ length were collected using EndoFLIP. ![]() Primary antireflux surgery was performed on 100 consecutive patients with pathologic reflux. provides reviews, contact information, driving directions and the phone number for Rasa Zarnegar, M.D. He is board certified in General Surgery and graduated from Chicago Med Schl in 1999. However, there are limited data on the relative contribution of critical steps during antireflux procedures to the functional integrity of the EGJ.

Interventions to treat reflux attempt to restore the integrity of the EGJ. The lower esophageal sphincter and crural diaphragm constitute the intrinsic and extrinsic sphincters of the EGJ, respectively. To quantify the contribution of key steps in antireflux surgery on compliance of the EGJ.
