Anatomical failure following laparoscopic antireflux surgery (LARS): does it really matter?

Area of Science:

• Gastroenterology
• Surgical Innovation
• Medical Imaging

Background:

• Laparoscopic antireflux surgery (LARS) failure rates range from 2-30%, with intrathoracic wrap herniation being a common anatomical failure.
• Assessing the anatomical integrity of crural repair and wrap post-LARS is crucial for understanding failure mechanisms.

Purpose of the Study:

• To evaluate the anatomical integrity of crural repair and wrap after LARS using marking clips.
• To compare anatomical outcomes with symptomatic results in patients who underwent LARS.

Main Methods:

• A prospective study of 50 patients undergoing LARS over 3 years.
• Postoperative X-rays and 6-month barium swallows were used to measure interclip distance, assessing crural repair and wrap separation.
• Patients completed standardized symptom questionnaires at 6 months.

Main Results:

• At 6 months, 22% showed mild and 54% moderate separation of the crural repair; 28% mild and 22% moderate separation of the wrap.
• Mild separation of both occurred in 3% and moderate in 16%, with no significant correlation to Visick scores.
• 14% demonstrated barium swallow evidence of failure, but only one case required re-do surgery due to symptomatic intrathoracic wrap migration.

Conclusions:

• A high prevalence of anatomical failure, indicated by increased interclip distance, is observed 6 months post-LARS.
• Despite high rates of anatomical separation, LARS anatomical failures do not consistently correlate with subjective symptom recurrence.
