Case Requirements & Fellow Volumes

Fellowship Council Requirements

Our fellowship carries both an Advanced GI/MIS and Bariatrics designation. Minimum case requirements for the fellows are as follows:

Advanced GI/MIS Case Requirements

150 total complex MIS cases

65 Defined category MIS cases

  • 20 foregut cases
  • 25 bariatric cases
  • 10 inguinal hernia
  • 10 ventral hernia

85 Additional Complex MIS Cases

  • MIS cholecystectomy, appendectomy, and diagnostic laparoscopy are considered basic MIS cases and do not count towards the case requirements.

50 Flexible Endoscopy Procedures

  • Upper or lower
  • Can be diagnostic or therapeutic
  • Can be intraoperative or as a separate procedure

Bariatric Case Requirements

Minimum of 100 bariatric cases

  • 50 cases must include an anastomosis
  • 10 restrictive cases
  • 5 revisional procedures


By completing the above case requirements, all fellows will complete the case volume requirements for an American Society of Metabolic and Bariatric Surgery (ASMBS) Fellowship Certificate and the SAGES Advanced GI MIS and Endoscopy (Comprehensive Flexible Endoscopy or Area of Concentrated Training Seal in Advanced Flexible Endoscopy) Certificate. There are additional requirements that the fellow needs to complete, all of which are integrated into the fellowship year.

  2. Completion and documentation of didactic educational sessions covering the ASMBS educational curriculum topics
  3. Participation in at least quarterly bariatric morbidity and mortality conferences
    Submission of an abstract to a national or regional society meeting during the fellowship
  4. Participation in bariatric multidisciplinary conferences
  5. Case volume requirements
    1. At least 100 bariatric procedures including 50 intestinal bypass operations, 10 restrictive operations, and 5 revisional procedures
  6. Patient evaluation requirements
    1. 50 preoperative evaluations, 100 postoperative inpatient management encounters, and 100 postoperative outpatient evaluations

Case Volumes for Past Fellows

Our program provides robust case volumes for the fellowship, as evidenced by the number of index cases performed by the fellows over the last 10 years. In addition to the index case volumes, fellows perform several hundred diagnostic and therapeutic endoscopies over the course of the year. All fellows have been able to meet the requirements for anastomotic cases set by the Fellowship Council and the ASMBS, in part, secondary to a large volume of revisional cases as well as multiple comprehensive bariatric surgery programs throughout the city for which UT faculty serve as medical directors.
