Crural Dissection in Sleeve Gastrectomy

An interventional study of Crura dissection and Sleeve gastrectomy in Sleeve Gastrectomy, sponsored by University of Miami. Terminated at 1 site in United States. Open to participants aged 18 Years to 69 Years. Per ClinicalTrials.gov, last updated 2025-06-03.

Sponsored by University of Miami · Not applicable, Interventional, and Treatment

Why this study was terminated
Changes in practice patterns. From COVID-related disruptions to the adoption of ERAS protocols and robotic surgery, there was significant variability in standards of care making direct comparison between groups impractical.

Study arms

  • Experimental
    Crura Dissection

    Participants with a visually detectable hiatal hernia at the time of sleeve gastrectomy procedure will undergo a crura dissection and hiatal hernia repair.

    Procedure: Crura dissection · Procedure: Sleeve gastrectomy · Procedure: Hiatal hernia repair

  • Experimental
    National Practice

    Participants with no detectable hiatal hernia will be randomized to either Group 2 or 3. Group 2 participants will be treated to the national practice patterns of complete dissection of the curvature of the stomach without dissection of the crura.

    Procedure: Sleeve gastrectomy

  • Experimental
    Standard of Care

    Participants with no detectable hiatal hernia will be randomized to either Group 2 or 3. Group 3 participants will undergo the institutional standard of care with the dissection of the crura.

    Procedure: Crura dissection · Procedure: Sleeve gastrectomy

Interventions

  • ProcedureCrura dissection

    The diaphragmatic crura, one of two tendon structures below the diaphragm, will be removed during the laparoscopic sleeve gastrectomy.

  • ProcedureSleeve gastrectomy

    Surgical weight-loss procedure in which the stomach is reduced to about 15% of its original size, by surgical removal of a large portion of the stomach along the greater curvature.

  • ProcedureHiatal hernia repair

    This involves tightening the opening in your diaphragm with stitches to keep your stomach from bulging upward through the opening in the muscle wall.

What researchers measure

Primary outcomes

  1. Change in Perioperative Symptoms as assessed by the Intermediate and Late-Post Operative Pain, Nausea and Dysphagia Questionnaire

    The Intermediate and Late Post-Operative Pain, Nausea and Dysphagia Questionnaire is a 7-item questionnaire with scores ranging 0-40 with the higher score indicating severe symptoms.

    Time frame: Day 1, 12 months

  2. Change in Perioperative Symptoms as assessed by the Rhodes Index of Nausea, Vomiting and Retching Questionnaire

    The Rhodes Index of Nausea, Vomiting and Retching Questionnaire is an 8-item questionnaire with scores ranging from 0 to 32 with a higher score indicating increased symptoms of nausea.

    Time frame: Day 1, 12 months

  3. Change in Perioperative Symptoms as assessed by the Gastroesophageal Reflux Disease-Questionnaire (GERD-Q)

    The GERD-Q has a scoring range between 0-18 with a higher score indicating increased likelihood of GERD.

    Time frame: Baseline, 12 months

  4. Change in Perioperative Symptoms as assessed by the Brief Esophageal Dysphagia Questionnaire (BEDQ)

    The BEDQ has a scoring range between 0-40 with a higher score indicating increased symptoms of dysphagia.

    Time frame: Baseline, 12 months

Secondary outcomes

  1. Correlation of the presence of hiatal hernias

    Correlation of the presence of hiatal hernias between pre-operative upper Gastrointestinal (GI) series and surgical findings.

    Time frame: Day 1
