Patient-tailored algorithm for laparoscopic cruroplasty standardization: comparison with hiatal surface area and medium-term outcomes.

Background: Different methods have been described for laparoscopic hiatoplasty and hiatus hernia (HH) repair. All techniques are not standardized and the choice to reinforce or not the hiatus with a mesh is left to the operating surgeon's preference. Hiatal surface area (HSA) has been described as an attempt at standardization; in case the area is > 4 cm2, a mesh is used to reinforce the repair. Objective: The aim of this study was to describe a new patient-tailored algorithm (PTA), compare its performance in predicting crura mesh buttressing to HSA, and analyze outcomes. Methods: Retrospective, single-center, descriptive study (September 2018–September 2021). Adult patients (≥ 18 years old) who underwent laparoscopic HH repair. Outcomes and quality of life measured with the disease-specific gastroesophageal reflux disease health-related quality of life (GERD-HRQL) and reflux symptom index (RSI) were analyzed. Results: Fifty patients that underwent laparoscopic hiatoplasty and Toupet fundoplication were included. The median age was 61 years (range 32–83) and the median BMI was 26.7 (range 17–36). According to the PTA, 27 patients (54%) underwent simple suture repair while crural mesh buttressing with Phasix-ST® was used in 23 (46%). According to the HSA, the median hiatus area was 4.7 cm2 while 26 patients had an HSA greater than 4 cm2. The overall concordance rate between PTA and HSA was 94% (47/50). The median hospital stay was 1.9 days (range 1–8) and the 90-day complication rate was 4%. The median follow-up was 18.6 months (range 1–35). Hernia recurrence was diagnosed in 6%. Postoperative dysphagia occurred in one patient (2%). The GERD-HRQL (p < 0.001) and RSI (p = 0.001) were significantly improved. Conclusions: The application of PTA for cruroplasty standardization in the setting of HH repair seems effective. While concordance with HSA is high, the PTA seems easier and promptly available in the operative theater with a potential increase in procedure standardization, reproducibility, and teaching.
