Update on the Durability and Performance of Collis Gastroplasty For Chronic GERD and Hiatal Hernia Repair At 4-Year Post-Intervention

Background: Collis gastroplasty (CG) remains an important procedure to lengthen the esophagus when indicated in patients undergoing fundoplication for longstanding refractory gastroesophageal reflux disease (GERD) or large hiatal hernias. Concerns over potential sequelae of CG such as dysphagia and worsening heartburn as well as questions regarding the durability of the procedure remain a subject of debate. In this study, 3 and 4-year postoperative data is presented assessing patient quality of life (QOL) measures for those undergoing laparoscopic antireflux surgery (LARS) with and without CG. Methods: Comparative review of a prospectively maintained GERD patient database was conducted between patients undergoing LARS with CG versus non-CG (NC) at two institutions between October 2004 and February 2019. Patient demographic, perioperative, and QOL data was analyzed at 3 and 4 years postoperatively using four validated instruments: the Reflux Symptom Index (RSI), Laryngopharyngeal Reflux QOL (LPR-QOL), Swallowing QOL (SWAL), and Gastroesophageal Reflux Disease-Health Related Quality of Life (GERD-HRQOL) surveys. Results: A total of 214 CG and 798 NC patients were included in this study. The CG group was older (66.1 ± 12.9 vs. 59.0 ± 14.1, p < 0.001), had a higher frequency of ASA class 3 patients (39.7% vs. 29.7%), and had greater proportion of comorbid disease compared to NG. The groups were parallel in BMI (Collis 28.4 ± 5.2 kg/m² vs. non-Collis 28.6 ± 5.3 kg/m², p = 0.673). Subset analysis revealed persistent benefits through 4 years reflected by survey results in both groups. There were no statistically significant differences in QOL outcomes between CG and NC. A majority of patients in both groups reported discontinuation of antireflux medications and satisfaction with surgical outcomes and symptom control. Conclusion: Long-term QOL outcomes after laparoscopic CG are comparable to patients treated with fundoplication alone in cases of long-standing GERD and hiatal hernias. Furthermore, CG patients enjoyed equivalent durability of the procedure without risk of subsequent dysphagia. Collis gastroplasty remains an important tool in the armamentarium of foregut surgeons.
