Impact of Crural Repair and Gastropexy During Laparoscopic Sleeve Gastrectomy

23 april 2026 uppdaterad av: Berk Topaloğlu, Van Training and Research Hospital

Impact of Concomitant Crural Repair and Gastropexy on Gastroesophageal Reflux and Postoperative Outcomes During Laparoscopic Sleeve Gastrectomy

This prospective, randomized comparative controlled study evaluated the impact of concomitant posterior crural repair and posterior gastropexy on postoperative reflux outcomes in patients undergoing laparoscopic sleeve gastrectomy (LSG). The study was completed with a total of 50 patients, with 25 patients in each group. Participants were allocated to either the control group, which received standard LSG, or the study group, which underwent LSG combined with systematic hiatal dissection, posterior crural repair, and posterior gastropexy. No patient had evidence of hiatal hernia on preoperative upper gastrointestinal endoscopy. The primary endpoint was postoperative reflux symptom burden at one-year follow-up, assessed using the Frequency Scale for the Symptoms of GERD (F-Scale) and the Gastroesophageal Reflux Disease Symptom Assessment Scale (GSAS). Secondary endpoints included operative time, postoperative complications, length of hospital stay, proton pump inhibitor use, postoperative weight loss, and concordance between preoperative endoscopy and intraoperative hiatal assessment.

Detaljerad beskrivning

Laparoscopic sleeve gastrectomy (LSG) is a highly effective and widely performed bariatric procedure; however, postoperative gastroesophageal reflux disease (GERD) remains a significant and challenging complication. The mechanisms underlying reflux post-LSG are multifactorial, including disruption of the gastroesophageal junction, decreased lower esophageal sphincter pressure, and intrathoracic migration of the gastric sleeve.

This prospective, randomized, comparative controlled study aims to evaluate the efficacy of incorporating systematic hiatal dissection, posterior crural repair, and posterior gastropexy into the standard LSG procedure to mitigate postoperative reflux. A total of 50 patients with severe obesity completed the study, with 25 patients in each of the following groups:

  1. Control Group (n=25): Underwent standard LSG.
  2. Study Group (n=25): Underwent standard LSG combined with systematic intraoperative hiatal dissection, posterior crural repair to approximate the crura, and posterior gastropexy by anchoring the gastric corpus to the prepancreatic fascia.

These additional steps aim to preserve normal gastric anatomy, maintain the anatomical position of the sleeve, and prevent intrathoracic migration. Patients were evaluated preoperatively and at a one-year postoperative follow-up. The primary outcome is the assessment of postoperative reflux symptom burden using two questionnaires: the Frequency Scale for the Symptoms of GERD (F-Scale) and the Gastroesophageal Reflux Disease Symptom Assessment Scale (GSAS). Secondary outcomes include a comparison of operative time, 30-day postoperative complications, length of hospital stay, postoperative weight loss (%EWL and %TWL), and changes in proton pump inhibitor (PPI) use. Additionally, the study assesses the concordance between preoperative endoscopic findings and intraoperative hiatal assessments in the study group.

Tidsram
Change in Gastroesophageal Reflux Symptom Burden Assessed by the Gastrointestinal Symptom Assessment Scale (GSAS)
Tidsram: Baseline within 4 weeks before surgery and 12 months postoperatively
The Gastrointestinal Symptom Assessment Scale (GSAS) is a validated self-administered questionnaire that assesses the severity and frequency of upper gastrointestinal symptoms over the preceding week. Each item is rated on a 4-point Likert scale, and reflux, dyspepsia, and total domain scores are calculated as the mean of their respective items, yielding scores ranging from 0 to 3. Higher scores indicate a greater symptom burden and a worse outcome; lower scores indicate a better outcome. The outcome is the change in GSAS reflux, dyspepsia, and total scores from the preoperative baseline to one year postoperatively, calculated as (postoperative score - preoperative score). Negative change values indicate symptomatic improvement.
Baseline within 4 weeks before surgery and 12 months postoperatively
Change in Gastroesophageal Reflux Symptom Burden Assessed by the Frequency Scale for the Symptoms of GERD (F-Scale)
Tidsram: Baseline within 4 weeks before surgery and 12 months postoperatively
The Frequency Scale for the Symptoms of GERD (F-Scale; also known as the FSSG) is a validated 12-item self-administered questionnaire that evaluates the frequency of gastroesophageal reflux disease symptoms. Each item is scored on a 5-point Likert scale ranging from 0 (never) to 4 (always). The instrument yields three scores: a reflux subscale score (7 items; range 0-28), a dyspepsia/dysmotility subscale score (5 items; range 0-20), and a total score (range 0-48). Higher scores indicate a greater symptom burden and a worse outcome; lower scores indicate a better outcome. The outcome is the change in F-Scale total, reflux subscale, and dyspepsia subscale scores from the preoperative baseline to one year postoperatively, calculated as (postoperative score - preoperative score). Negative change values indicate symptomatic improvement.
Baseline within 4 weeks before surgery and 12 months postoperatively
