  Purpose

This study is prospective randomized trial enrolling at least 100 participants which compares efficacy and safety of two alternative methods of laparoscopic hiatal repair for large (i.e. with hiatal surface area (HSA) ranging from 10 to 20 sq.cm, which corresponds to diameter of defect from 5 to 8 cm) types I, II, and III hiatal hernias: primary crural repair and repair with partially absorbable lightweight mesh. According to the literature, rates of anatomical failure and recurrence of GERD after primary repair of large hiatal hernias reach 42 %. Mesh repair decreases rates of failures, however, polypropylene and composite PTFE meshes used most widely, result in unacceptable rates of long-term dysphagia and oesophageal strictures. Our own experience of more than 400 repairs using partially absorbable lightweight mesh Ultrapro (Ethicon) and original sub-lay technique of its fixation precluding contact of the mesh with the oesophagus, showed low recurrence rate and a few cases of long-term dysphagia. Thus, final conclusions could be established by prospective randomized study. Our hypothesis is: original technique of lightweight mesh repair is highly effective for prevention of recurrences compared to primary repair and safe in terms of mesh-related dysphagia and oesophageal strictures. The long-term results (24 months post surgery for every patient) will be studied using symptom questionnaires, quality of life and satisfaction questionnaires, barium studies, endoscopic examinations, 24-hour pH testing, and analysis of possible reoperations.

Primary Outcome Measures:
  • Anatomical and functional recurrence of hiatal hernia and GERD [ Time Frame: 24 months ] [ Designated as safety issue: No ]
    Recurrence of hiatal hernia, i.e. anatomical recurrence, will be assessed by symptom questionnaire with visual analogue scales, MAINLY by barium study, and data from possible redo procedures. Recurrence of GERD, i.e. functional recurrence, will be evaluated by symptom questionnaire with visual analogue scales, endoscopic examination with assessment of degree of reflux-oesophagitis according to Los-Angeles classification, and 24 hour pH-testing with calculation of DeMeester score.


Secondary Outcome Measures:
  • Repair-related dysphagia/oesophageal stricture/prosthetic erosion [ Time Frame: 24 months ] [ Designated as safety issue: Yes ]
    Short- and long-term dysphagia, including due to repair-related oesophageal stricture, will be assessed by symptom questionnaire with visual analogue scales, barium study, endoscopic examination, and data from possible redo procedures. Patients also will be endoscopically assessed for such rare complication as prosthetic erosion of oesophagus.

  • Quality of life and satisfaction [ Time Frame: 24 months ] [ Designated as safety issue: Yes ]
    Quality of life and satisfaction will be assessed by GERD-HRQL score

  • Operative time [ Time Frame: 1 day ] [ Designated as safety issue: No ]
  • Morbidity [ Time Frame: 1 month ] [ Designated as safety issue: Yes ]
  • Postoperative hospital stay [ Time Frame: 1 month ] [ Designated as safety issue: Yes ]
  • Influence on extra-oesophageal complications [ Time Frame: 24 months ] [ Designated as safety issue: No ]
    Extra-oesophageal complications to be assessed are: asthma, COPD, laryngitis, angina, and arrhythmias


Estimated Enrollment: 100

Arms Assigned Interventions
Active Comparator: Lightweight mesh repair
Laparoscopic hiatal repair with sub-lay partially absorbable lightweight mesh
Procedure: Laparoscopic hiatal repair with sub-lay partially absorbable lightweight mesh
A fashioned according to the dimensions of hernia defect partially absorbable lightweight mesh Ultrapro™ (Ethicon, Inc.) will be sutured to both crura with 3 to 5 interrupted non-absorbable (Ethibond™ 3-0 by Ethicon, Inc.) sutures (as tension-free repair). Subsequent 2 to 3 interrupted non-absorbable sutures will approximate crura to completely cover a mesh to preclude its contact with the esophagus (original "sandwich" sub-lay technique).
Other Names:
  • Laparoscopic mesh hiatoplasty
  • Laparoscopic mesh hiatal closure
Active Comparator: Primary crural repair
Laparoscopic primary posterior crural repair
Procedure: Laparoscopic primary posterior crural repair

Posterior cruroraphy will be performed with 3 to 4 interrupted non-absorbable (Ethibond™ 3-0 by Ethicon, Inc.) sutures.

In the both arms laparoscopic procedure will be done in a standard fashion: reduction of hernia with excision of hernia sac and mobilization of distal esophagus, exposure of borders of hiatal opening including crura posteriorly to esophagus, repair if hiatal hernia defect (30 Fr esophageal bougie is used), a short (2,5 - 3,5 cm) 360° fundoplication wrap (floppy-Nissen procedure) (30 Fr esophageal bougie is used).

Other Names:
  • Laparoscopic posterior crurorrhaphy
  • Laparoscopic posterior crural closure
