Hiatal Hernia Repair by Tension-free Mesh Closure or Simple Suturing
Study Details
Study Description
Brief Summary
One-hundred and fifty-nine patients undergoing Nissen fundoplication for symptomatic gastro-oesophageal reflux disease (GORD), who had a concomitant hiatal hernia of > 2 cm axial length, were randomized to closure of the diaphragmatic hiatus with either crural sutures alone or tension-free closure with a non-absorbable mesh. Primary outcome variable was the incidence of radiologically verified recurrent hiatal hernia. Secondary outcomes were per-and postoperative complications and courses, symptomatic recurrence rate, use of PPI, postoperative oesophageal acid exposure and Quality of Life.

Detailed Description
The basic principles behind successful surgical repair of the anatomy and function of the gastro-oesophageal junction (GOJ) in gastro-oesophageal reflux disease (GORD) is not only to encircle the distal oesophagus and GOJ by the fundic wrap but also to complete a transhiatal reduction of a concomitant hiatal hernia (type I, HH), aiming for a 2 - 3 cm intra-abdominal length of the of oesophagus and to transact a tension-free hiatal closure. The physiological and morphological characteristics of the diaphragmatic hiatus, however, carry a challenge for the selection of the ideal technique for surgical repair. The diaphragmatic hiatus consists of a three-dimensional structure in constant motion, which creates a border between the counteracting pressures prevailing in the abdominal and chest cavities, respectively. Following hernia reduction, the structural quality of the diaphragmatic pillars is usually weak, offering poor support for the subsequent closure with risk for high recurrence rates. These and other considerations have encouraged the exploration of mesh reinforcement to enhance the durability of the hiatal closure.

Outcome Measures
Primary Outcome Measures
- Recurrent hiatal hernia [12 month]
The incidence of radiologically verified recurrent hiatal hernia. Examined in the erect position after a 4-hour fast when 250 ml of low-density barium sulphate suspension (45% weight per volume) was ingested. The patients were instructed to drink the served volume within 30 seconds. Thereafter three sagittal spot films (35 x 35 cm) of the distal esophagus and GEJ were exposed 1, 2 and 5 minutes after the start of the barium ingestion (16). In
Secondary Outcome Measures
- Complications [from operation day up to 12 month]
Number of patients who had a bleeding or a leakage that requires a intervention, either blood transfusion or reoperation.
- Proton pump inhibitor (PPI) [12 month]
Use of PPI
- Quality of Life, physical and mental score: SF-36 [12 month]
The Swedish version of the validated global Short Form -36 (SF-36) questionnaire was used and data are presented as physical and mental summary component scores (PCS and MCS, respectively).
- Postoperative oesophageal acid exposure [12 month]
Ambulatory 24-hour pH-monitoring was performed by use of a slim-line dual probe catheter system (single-use, 2 sensors, 15 cm spacing, ΓΈ 1.8 mm, Medtronic A/S, Skovlunde, Denmark). The oesophageal pH probe was positioned 5 cm above the upper border of the LOS as determined by manometry. Total time in percent of the total recording time with pH <4 was determined
- Gastrointestinal symptom rating scale (GSRS) [12 month]
A validated questionnaire containing five dimensions of abdominal symptoms (gastroesophageal reflux, abdominal pain, indigestion, obstipation and diarrhea).
- Dysphagia [12 month]
Dysphagia for liquids and solids were recorded within a four-graded scale stating the frequency of dysphagia episodes with an arbitrary (empirical) cut off for clinical significance. The same dysphagia scoring was also used in a previous rct, from the same institution, comparing different types of antireflux procedures in open surgery.
