Dual-sided composite mesh repair of hiatal hernia: Our experience and a review of the Chinese literature

Mesh Versus No Mesh for Cruroplasty

This review describes the evolution of hiatal hernia repair for the past several decades: From the use of a primary tissue repair only, the subsequent inclusion of synthetic mesh and its complications, to current day indications for mesh use. We will highlight the recent research in biologic and composite meshes as well as the ongoing limitations in studying their efficacy. Finally, we will describe our institutional indications and surgical technique practices in the utilization of biologic mesh.

Platelet-rich plasma PRP vs. absorbable mesh as cruroplasty reinforcement: a study on an animal model

BACKGROUND

Reinforcement of posterior cruroplasty has been proposed to minimize the failure of hiatal hernia repair (HHR). The applications of autologous platelet-rich plasma (PRP) and absorbable mesh are barely reported in this area.

AIMS

To analyze local macroscopic and microscopic changes induced by mesh vs. PRP as reinforcement of HHR, using a reliable laparoscopic experimental porcine model.

MATERIAL AND METHODS

This prospective, comparative pilot study was conducted on 14 female pigs, aged four to six months. An iatrogenic hiatal defect was laparoscopically simulated and repaired, reinforced with Bio-A® mesh (group A) or PRP (group B). Specimen retrieval was performed after seven months for histopathological (HP) examination.

RESULTS

No local or general complications were registered, with complete resorption of reinforcements, that determined inflammatory infiltrates with local collagen production and tissue neo-vascularization. Group A had an increased mean chronic inflammation score (p = .3061), showing significant sclerotic collagenizing process. PRP enhanced angiogenesis, collagenizing, myofibroblast recruitment and tissue ingrowth.

CONCLUSIONS

No residual materials or evidence of anatomical distortion were found. Animal model was safe and reliable. This is the first report of complete absorption of Bio-A^® positioned on crural area. HP results suggest the clinical application of PRP in HHR as a promising co-adjuvant to local remodeling and healing.Abbreviations: ASA: American Society of Anesthesiologists; AB: Alcian Blue; PAS: Periodic Acid-Schiff; CP: platelet concentrate; fPC: filtered plasma concentrate; GERD: gastro-esophageal reflux disease; HSA: hiatal surface area; HHR: hiatal hernia repair; HP: histopathological; HH: hiatal hernia; HE: hematoxylin and eosin; HR: hiatus repair alone; HRM: hiatus repair and acellular dermal matrix; NM: Nicolae Manolesccu; LNF: laparoscopic Nissen fundoplication; PC: posterior cruroplasty; PPP: platelet-poor plasma; RP: platelet-rich plasma.

Tension-Free Inlay Repair of Large Hiatal Hernias Using Dual-Sided Composite PTFE/ePTFE Meshes in Laparoscopic Surgery for Gastroesophageal Reflux Disease

BACKGROUND

Patients with gastroesophageal reflux disease (GERD) also frequently suffer from concomitant hiatal hernia. It has been described that a preoperative hiatal hernia of ≥3 cm is associated with a more than threefold relative risk for reflux symptom recurrence after fundoplication without mesh reinforcement. In this report, we describe our experience with the implantation of dual-sided composite PTFE/ePTFE meshes in a tension-free fashion during laparoscopic antireflux surgery (LARS).

METHODS

A prospective database containing data of all patients undergoing LARS and hiatal hernia repair with mesh implantation from January 2009 until December 2014 was interrogated. Ten patients with preoperative esophageal high resolution manometry and 24-hour pH impedance monitoring because of symptoms suggestive of GERD who received hiatal repair using dual-sided meshes in inlay technique were identified and included in this analysis.

RESULTS

There were no conversions to open surgery in the study group. Median operative time was 138 minutes (interquartile range Q1-Q3: 119-151 minutes) and average length of postoperative stay was 3.5 days (interquartile range Q1-Q3: 2.3-4.0 days). During a median follow-up period of 43.3 months (interquartile range Q1-Q3: 18.9-47.1 months), no redo operations had to be performed. Noteworthy, 2 patients complained about dysphagia (20%) during follow-up, but symptoms resolved after endoscopic interventions.

CONCLUSIONS

Tension-free inlay repair of large hiatal hernias using dual-sided composite PTFE/ePTFE meshes during LARS provides promising results. It provides satisfactory symptom relief and prolonged control of GERD. Further studies to validate its efficiency in a larger collective are needed.

Dual mesh repair for a large diaphragmatic hernia defect: An unusual case report

•

Delayed right sided of diaphragm rupture or hernia is a rare.

•

Most of the diaphragmatic hernia patients are asymptomatic.

•

The main treatment approach is repair of the diaphragmatic hernia defect after reduction of the organs and tissues into the abdominal cavity.

•

A dual mesh repair can be used for a large diaphragm hernia.

Introduction

Diaphragmatic hernia secondary to traumatic rupture is a rare entity which can occur after stab wound injuries or blunt abdominal traumas. We aimed to report successfully management of dual mesh repair for a large diaphragmatic defect.

Case report

A 66-year-old male was admitted with a right sided diaphragmatic hernia which occurred ten years ago due to a traffic accident. He had abdominal pain with worsened breath. Chest X-ray showed an elevated right diaphragm. Further, thoraco-abdominal computerized tomography detected herniation a part of the liver, gallbladder, stomach, and omentum to the right hemi-thorax. It was decided to diaphragmatic hernia repair. After an extended right subcostal laparotomy, a giant right sided diaphragmatic defect measuring 25 × 15 cm was found in which the liver, gallbladder, stomach and omentum were herniated. The abdominal organs were reducted to their normal anatomic position and a dual mesh graft was laid to close the diaphragmatic defect. Patients’ postoperative course was uneventful.

Discussion

Diaphragmatic hernia secondary to trauma is more common on the left side of the diaphragm (left/right = 3/1). A right sided diaphragmatic hernia including liver, stomach, gallbladder and omentum is extremely rare. The main treatment of diaphragmatic hernias is primary repair after reduction of the herniated organs to their anatomical position. However, in the existence of a large hernia defect where primary repair is not possible, a dual mesh should be considered.

Conclusion

A dual mesh repair can be used successfully in extensive large diaphragmatic hernia defects when primary closure could not be achieved.

The importance of the mesh shape in preventing recurrence after Nissen fundoplication

Gastro esophageal reflux disease (GERD) is the most common gastrointestinal disorder and often is associated with hiatal hernia (HH). Nissen fundoplication is the most common surgical treatment method. Despite surgical treatment, recurrence rate is still high. In this study, we aimed to identify the importance of the mesh shape in preventing recurrence after Nissen fundoplication. A hundred twenty two patients who operated Nissen fundoplication owing to GERD and/or HH were evaluated. Nissen fundoplication was made all patients. Patients were divided into three groups according to hiatoplasty procedure; group 1 (V-shaped mesh), group 2 (V-shaped mesh + Fibrin glue), and group 3 (special designed mesh, Kar's mesh). Groups were compared regarding intraoperative, postoperative early- and long-term complications. Mean age was 42.75 years, and male to female ratio was 1:2.98. The mean follow-up period was 27 mounts. There was no mortality during follow-up. The most common presenting symptom was heartburn (93.4%). There wasn't difference between groups in terms of the intraoperative complications and postoperative early-term complications. The overall recurrences rate was 4.9% and dysphagia > 3 months rate was 1.6%. No recurrence was not observed in group 3, while recurrence was observed in 4 patients in group 1 (P = 0.030). Patients should be carefully selected for surgery because complication rate is high despite successful anti-reflux surgical treatment. In this study, we have used a special designed mesh. We believe that this special designed mesh can be used safely and effectively in anti-reflux surgery because recurrence and complications were not observed.
