The aim of the study was to study the indications for the use of mesh implants in patients with large hiatal hernias, depending on the tension of the crura.

Materials and methods. Using a Walcom Fm-204-50k digital force gauge, we measured the force of crural tension during laparoscopic cruroraphy in 115 patients who met the inclusion criteria for participation in the study. All patients underwent intraoperative measurement of the tension force of the crura during the crura repair. All patients, whose tensile strength during measurement was > 4 N (n=69), were randomly divided into two groups. The first group included 30 patients who underwent hiatal hernia repair using a collagen-coated Parietex mesh implant. The second group included 39 patients who underwent simple suturing of the crura (cruroraphy).

Results. The main and control groups did not differ significantly in terms of age, gender, quality indicator and the area of hiatal surface (p>0.05). According to the results of measuring the tension of the sutures during cruroraphy, the average tensile force of the suture closest to the esophagus was 5.2 (from 4.0 to 8.2 N). When performing anterior cruroraphy, the tensile force of the seams averaged 3.5 N (from 2.4 to 4.7 N). Over an average follow-up period of 48 months, anatomical relapses were revealed in 1 patient of group I and in 6 patients of group II (p=0.004). Patient satisfaction was significantly higher in the mesh implant group (p=0.004). The mesh group showed a greater improvement in GERD-HRQL (p<0.0001) compared to the non-mesh group.

Conclusion. Laparoscopic repair of large hiatal hernias using a collagen-coated Parietex mesh implant in patients with a cruraraphy suture pull force > 4 N is safe and can prevent anatomical recurrence.

Key words: hernia of the esophageal orifice of the diaphragm, laparoscopic cruroraphy, measuring the tension of the seams of the cruroraphy.
