Changes in esophageal physiology after paraesophageal hernia repair and Collis gastroplasty

[Collis gastroplasty in surgical treatment of hiatal hernia]

OBJECTIVE

To analyze the early and long-term postoperative outcomes after Collis gastroplasty in the treatment of patients with hiatal hernia complicated by gastroesophageal reflux disease and shortening of the esophagus.

MATERIAL AND METHODS

Postoperative outcomes after Collis gastroplasty were analyzed in 22 patients with hiatal hernia and shortening of the esophagus. The control group consisted of 166 patients after simple repair of hiatal hernia without Collis procedure.

RESULTS

In case of Collis gastroplasty, surgery time was 185 (160-250) min. Intraoperative complications were observed in 3 (13.6%) patients, incidence of postoperative complications - 18.2%. There were no lethal outcomes in this group of patients. Mild functional dysphagia was observed in 2 (9.1%) patients. Length of hospital stay was 7.8±2.4 days. Mean follow-up was 34 (6-52) months. There were no anatomical recurrences. A relapse of gastroesophageal reflux was noted in 1 (4.6%) case. GERD-HRQL score was 4.8±2.2 points. Additional Collis gastroplasty did not affect the immediate and long-term results of surgical treatment in comparison with simple cruroraphy and fundoplication.

CONCLUSION

Unreduced shortening of the esophagus may be followed by high incidence of recurrent hiatal hernia and GERD in long-term period. In case of shortening of the esophagus, surgery should include Collis gastroplasty. This effective and safe procedure does not impair treatment outcomes. Indications and optimal technique of Collis gastroplasty require clarification and further research.
