Hiatal hernia recurrences after laparoscopic surgery: exploring the optimal technique

Area of Science:

• Gastroenterology
• Surgical Innovation
• Hernia Repair

Background:

• Laparoscopic hiatal hernia repair recurrence rates range from 25-42%.
• Long-term efficacy of reinforcement techniques like anterior sutures, vertical mesh strips (VMS), or mesh is unclear.
• High recurrence necessitates evaluating methods to improve surgical outcomes.

Purpose of the Study:

• To determine the recurrence rate of hiatal hernia after laparoscopic surgery.
• To assess if reinforcement techniques can reduce long-term recurrence.

Main Methods:

• Retrospective cohort study of 307 patients undergoing laparoscopic fundoplication (2012-2019).
• Hiatal hernia recurrence assessed via computed tomography.
• Statistical analysis included logistic regression to evaluate reinforcement techniques.

Main Results:

• Overall hiatal hernia recurrence rate was 20.8% over a mean 6-year follow-up.
• Use of VMS during primary surgery was significantly associated with fewer recurrences (OR=0.34, p=0.048).
• 17.6% of patients required secondary surgery for recurrence.

Conclusions:

• The recurrence rate of hiatal hernia after laparoscopic repair is substantial.
• Vertical mesh strips (VMS) show promise in reducing long-term recurrence after primary repair.
• Further investigation into VMS for hiatal hernia repair is warranted.
