Functional Results after Repair of Large Hiatal Hernia by Use of a Biologic Mesh

Hiatal Hernia Repair With Tension-Free Mesh or Crural Sutures Alone in Antireflux Surgery: A 13-Year Follow-Up of a Randomized Clinical Trial

Importance

Antireflux surgery is an effective treatment of gastroesophageal reflux disease (GERD), but the durability of concomitant hiatal hernia repair remains challenging. Previous research reported that the use of a mesh-reinforced, tension-free technique was associated with more dysphagia for solid foods after 3 years without reducing hiatal hernia recurrence rates compared with crural sutures alone, but the long-term effects of this technique have not been assessed.

Objective

To assess the long-term anatomical and functional outcomes of using a mesh for hiatal hernia repair in patients with GERD.

Design, Setting, and Participants

A double-blind, randomized clinical trial was performed at a single center (Ersta Hospital, Stockholm, Sweden) from January 11, 2006, to December 1, 2010. A total of 159 patients were recruited and randomly assigned. Data for the current analysis were collected from September 1, 2021, to March 31, 2022. All analyses were conducted with the intention-to-treat population.

Interventions

Closure of the diaphragmatic hiatus with crural sutures alone vs a tension-free technique using a nonabsorbable polytetrafluoroethylene mesh (Bard CruraSoft).

Main Outcomes and Measures

The primary outcome was radiologically verified recurrent hiatal hernia after more than 10 years. Secondary outcomes were dysphagia scores (ranging from 1 to 4, with 1 indicating no episodes of dysphagia and 4 indicating more than 3 episodes of dysphagia per day) for solid and liquid foods, generic 36-Item Short Form Health Survey and disease-specific Gastrointestinal Symptom Rating Scale symptom assessment scores, proton pump inhibitor consumption, and reoperation rates. Intergroup comparisons of parametric data were performed using t tests; for nonparametric data, Mann-Whitney U, χ2, or Fisher exact tests were used. For intragroup comparisons vs the baseline at follow-up times, the Friedman test was used, and post hoc analysis was performed using Wilcoxon matched pairs.

Results

Of 145 available patients, follow-up data were obtained from 103 (response rate 71%; mean [SD] age at follow-up, 65 [11.3] years; 55 [53%] female), with 53 initially randomly assigned to mesh reinforcement, and 50 to crural suture alone. The mean (SD) follow-up time was 13 (1.1) years. The verified radiologic hiatal hernia recurrence rates were 11 of 29 (38%) in the mesh group vs 11 of 35 (31%) in the suture group (P = .61). However, 13 years postoperatively, mean (SD) dysphagia scores for solids remained significantly higher in the mesh group (mean [SD], 1.9 [0.7] vs 1.6 [0.9]; P = .01).

Conclusions and Relevance

Findings from this long-term follow-up of a randomized clinical trial suggest that tension-free crural repair with nonabsorbable mesh does not reduce the incidence of hiatal hernia recurrence 13 years postoperatively. This finding combined with maintained higher dysphagia scores does not support the routine use of tension-free polytetrafluoroethylene mesh closure in laparoscopic hiatal hernia repair for treatment of GERD.

Laparoscopic fixation of biological mesh at hiatus with glue and suture during hiatal hernia repair

BACKGROUND

Laparoscopic paraesophageal hernia repair is associated with higher recurrence rate. Mesh is used to reduce the recurrence rate. This retrospective study is to review our experience of biological mesh fixed with suture and medical glue in hiatal hernias repairs.

METHODS

A retrospective chart review was conducted for a consecutive series of patients undergoing laparoscopic hiatal herniorrhaphy between January 2018 and January 2019. After hiatus closure, a piece of biological prosthesis was fixed with medical glue and suture for reinforcement of the crural closure. Clinical outcomes were reviewed, and data were collected regarding operative details, complications, symptoms, and follow-up imaging. Radiological evidence of any size of hiatal hernia was considered to indicate a recurrence.

RESULTS

Thirty-six patients underwent surgery uneventfully without any serious complication. There was no mortality. The follow-up was, on average, 18.4 months, and there was no symptomatic recurrence. There was one anatomical recurrence without any related presentation. The method of mesh fixation with medical glue and suture took 12 min on average, and the handling was fairly easy.

CONCLUSIONS

Biological mesh fixed with suture and medical glue was safe and effective for repairing large hiatal hernias. Of course, a longer follow-up is still needed for determining long-term outcomes.

Mesh-related complications in paraoesophageal repair: a systematic review

BACKGROUND

Paraoesophageal hernias (PEH) have a high recurrence rate, prompting surgeons to consider the use of mesh reinforcement of the hiatus. The risks and benefits of mesh augmentation in PEH repair are debated. Mesh-related complications including migration and erosion are considered in this publication.

DESIGN

A systematic literature review of articles published between 1970 and 2019 in Medline, OVID, Embase, and Springer database was conducted, identifying case reports, case series and observational studies of PEH repair reporting mesh-related complications.

RESULTS

Thirty-five case reports/series of 74 patients and 20 observational studies reporting 75 of 4200 patients with mesh complications have been included. The incidence of mesh-related erosions in this study is 0.035%. PTFE, ePTFE, composite and synthetic meshes were frequently associated with mesh erosion requiring intervention. Complete erosions are often managed endoscopically while partial erosions may require surgery and resection of the oesophagus and/or stomach.

CONCLUSIONS

Mesh-related complication is rare with dysphagia a common presenting feature. Mesh erosion is associated with synthetic mesh more frequently in the reported literature. A mesh registry with long-term longitudinal data would help in understanding the true incidence of mesh-related complications.

The use of biosynthetic mesh in giant hiatal hernia repair: is there a rationale? A 3-year single-center experience

PURPOSE

Reinforced prosthetic crural repair is particularly indicated for giant hiatal hernias. The rationale is to reduce the recurrence rate in the long term. The aim of our study is to evaluate the outcomes of laparoscopic giant hiatal hernia repair using a biosynthetic mesh.

METHODS

We retrospectively analyzed 44 patients who underwent laparoscopic mesh-reinforced hiatal closure and fundoplication using a biosynthetic material. Inclusion criterion was large hiatal defects (> 5 cm). Follow-up was scheduled at 6, 12 and 36 months after surgery.

RESULTS

44 patients (29F) with a mean age of 62 years (range 14-85) and mean of BMI 24.5 kg/m² (range 21-29) underwent successful laparoscopic repair. Twenty-six (59.1%) patients had Nissen-Rossetti fundoplication, whereas 18 (40.9%) had Toupet fundoplication. Six-month questionnaire for the evaluation of symptoms was available for 43 patients (97.7%) and for 40 (90.9%) patients at 12 and 36 months. Mean preoperative symptoms score analysis was 1.68 ± 0.73. Mean scores at each follow-up time were significantly improved compared to baseline (p > 0.05). Barium swallow was available in 37 patients (84.1%) at 1 year after surgery. Radiologic recurrence was observed in two patients (4.5%). No patient had symptoms attributable to recurrence or required revisional surgery. There were no mesh-related complications at 3 years follow-up.

CONCLUSIONS

The use of biosynthetic mesh for crural reinforcement is associated with a low incidence of mesh-related complications and with a reasonably low recurrence rate (4.5%) at 36 months. However, additional data with longer follow-up are needed to determine long-term safety and efficacy.

Anatomic Observation of Recurrent Hiatal Hernia: Recurrence or Disease Progression?

BACKGROUND

Recurrence after hiatal hernia repair is common. The causes are uncertain. Our observation is the site of recurrence is primarily the nonsutured or nonreinforced anterior-left lateral portion of the hiatus. Our aim was to assess the distribution of hiatal hernia recurrence location as a basis for developing a theory of recurrence.

METHODS

Consecutive patients who underwent repair of recurrent hiatal hernias from March 2012 to December 2019 were reviewed. Data collected included age, sex, date of operation, location of hiatal hernia recurrence, operative approach, method of hiatal hernia repair, fundoplication performed, need for gastrectomy, and additional procedures.

RESULTS

One hundred and eight consecutive patients were studied. The distribution of recurrence locations was as follows: anterior 67%, posterior 12%, and circumferential 21%. Foreshortened esophagus was a contributing factor in 12%. Median time from the original repair to recurrence was 1.5 years (interquartile range 0.9 to 3.75 years) for posterior recurrences, 2.75 years (interquartile range 1.15 to 8.5 years) for circumferential recurrences, and 3.25 years (interquartile range 1.38 to 10 years) for anterior recurrences. Recurrences were repaired in a variety of techniques, depending on the clinical circumstances.

CONCLUSIONS

Hiatal hernia recurrences due to failure of the crural closure were less common, but early, recurrences. The majority of recurrences were due to stretching of the hiatus anterior and to the left of the esophagus. We theorize that the pathophysiology of late hiatal hernia recurrence is widening of the anterior and left lateral portion of the hiatus secondary to repeated stress from differential pressures that eventually overcomes the tensile strength of the hiatus.

Paraesophageal Hiatal Hernia Repair With Urinary Bladder Matrix Graft

Background and Objectives:

Paraesophageal hiatal hernia repair can be performed with or without mesh reinforcement. The use, technique, and mesh type remain controversial because of mixed reports on mesh-related complications. Short-term outcomes have become important in all forms of surgery.

Methods:

From January 2012 through April 2017, all patients who underwent isolated hiatal hernia repair in our center were reviewed. Concomitant bariatric surgery cases were excluded. Repairs reinforced by porcine urinary bladder matrix (UBM) graft were compared to non-UBM repairs. Statistical comparison was based on a Wilcoxon 2-sample test or Fisher's exact test.

Results:

We reviewed 239 charts; 110 bariatric cases and 8 cases with non-UBM reinforcement were excluded. We identified 121 patients: 56 UBM-reinforced (46.3%) versus 65 non-UBM (53.7%). Sixteen (28.6%) UBM cases were male versus 23 (35.4%) non-UBM cases. The UBM patients were significantly older (63.9 versus 54.3; P = .001). There was no difference in mean BMI (29.6 vs 28.5; P = .28). Cases were performed laparoscopically (60.7% vs 67.7%; P = .45) or robotically (39.3% vs 32.3%; P = .45), with no conversions to open. The UBM group had a longer mean operative time (183 minutes vs 139 minutes; P = .001).There was no difference in median length of stay (2 days vs 2 days; P = .09) or 30-day readmission rate (7.1% vs 7.5%; P =.99). Postoperative complications were graded according to the Clavien-Dindo classification, and there was no difference (19.6% vs 9.2%; P = .12).

Conclusions:

Hiatal hernia repair with UBM reinforcement can be performed safely with no increase in postoperative complications.

Hiatal hernia involving prolapse of the entire stomach into the mediastinum after distal gastrectomy: a case report

Background

Prolapse of a small part of the proximal stomach through the hiatus into the mediastinum is relatively common. Hiatal hernia involving the postoperative stomach has been reported previously, but the degree of hernia was not so severe, and hiatal hernia involving the prolapse of the entire stomach following gastrectomy into the mediastinum has never been reported. We describe a very rare case of large hiatal hernia involving the entire postoperative stomach.

Case presentation

A 79-year-old man with a history of distal gastrectomy for submucosal benign tumor 40 years ago was referred to our hospital because of dysphagia and weight loss. Computed tomography revealed prolapse of the entire postoperative stomach into the mediastinum, and a radical operation was performed. There was a strong adhesion in the hernial sac of the mediastinum, but only little adhesion due to a previous open surgery in the abdominal cavity was present. After the stomach was pulled into the abdominal cavity, suture cruroplasty and Toupet fundoplication without dissection of the short gastric artery were performed. The patient experienced postoperative paralytic ileus, but the rest of the postoperative course was uneventful and the symptom of dysphagia improved.

Conclusions

We presented a very rare large hiatal hernia involving the entire postoperative stomach. Toupet fundoplication preserving the short gastric artery could be one of the optimal surgeries to prevent postoperative regurgitation of the remnant stomach.
