Results of a Prospective Cohort Study on Open Rives Technique of the Midline Incisional Hernia: Midline Closure and Mesh Overlap

Background. Rives repair has been traditionally used for large abdominal wall defects with good results on terms of recurrence. However, it is limited by the lateral border of the posterior rectus sheath. The objective of our study was to evaluate recurrence rate, midline closure and mesh overlap in patients operated on elective midline incisional hernia by open Rives retromuscular repair. Methods. This is a prospective observational study of 83 patients who underwent elective open Rives technique between January 2014 and December 2018. Main inclusion criteria were adults with a midline incisional hernia. Recurrence, midline closure and mesh overlap were determined. Results. At a median postoperative follow-up of 32 (5-59) months, 8 cases of recurrence were reported. Patients with recurrence had wider hernia defects (101 ± 52 mm vs 66 ± 36 mm, P = .014) and were repaired with wider meshes (191 ± 93 mm vs 137 ± 68 mm, P = .042). However, although it was not statistically significant, midline closure was lower (38% vs 59%), as well as the overlapping relationship between mesh area and hernia defect area (2.937:1 vs 3.732:1) on patients that developed a recurrence. Conclusions. Rives technique provides good mid-term results in a midline incisional hernia (10% of recurrence at 36 months), including wider hernias in the recurrent cohort. The authors believe that other techniques which allow midline closure and placement of bigger meshes should be considered, especially in those hernias classified as W3 on EuraHS classification (more than 10 cm on width size).

Second Look After Retromuscular Repair With the Combination of Absorbable and Permanent Meshes

Objective: The aim of this study is to describe the macroscopic features and histologic details observed after retromuscular abdominal wall reconstruction with the combination of an absorbable mesh and a permanent mesh.Methods: We have considered all patients that underwent abdominal wall reconstruction (AWR) with the combination of two meshes that required to be reoperated for any reason. Data was extracted from a prospective multicenter study from 2012 to 2019. Macroscopic evaluation of parietal adhesions and histological analysis were carried out in this group of patients.Results: Among 466 patients with AWR, we identified 26 patients that underwent a reoperation after abdominal wall reconstruction using absorbable and permanent mesh. In eight patients, the reoperation was related to abdominal wall issues: four patients were reoperated due to recurrence, three patients required an operation for chronic mesh infection and one patient for symptomatic bulging. A miscellanea of pathologies was the cause for reoperation in 18 patients. During the second surgical procedures made after a minimum of 3 months follow-up, a fibrous tissue between the permanent mesh covering and protecting the peritoneum was identified. This fibrous tissue facilitated blunt dissection between the permanent material and the peritoneum. Samples of this tissue were obtained for histological examination. No case of severe adhesions to the abdominal wall was seen. In four cases, the reoperation could be carried out laparoscopically with minimal adhesions from the previous procedure.Conclusions: The reoperations performed after the combination of absorbable and permanent meshes have shown that the absorbable mesh acts as a protective barrier and is replaced by a fibrous layer rich in collagen. In the cases requiring new hernia repair, the layer between peritoneum and permanent mesh could be dissected without special difficulty. Few intraperitoneal adhesions to the abdominal wall were observed, mainly filmy, easy to detach, facilitating reoperations.

Is the sublay self-gripping mesh effective for incisional ventral hernia repair? Our experience and a systematic review of the literature

Sublay mesh repair seems to be the most effective method for treating incisional hernias (IHs). The aim of this study was to report our experience with retromuscular repair and self-gripping mesh for the treatment of midline IHs. In addition, we provided a systematic review of the literature regarding the use of this novel combination. All patients undergoing elective IH repair from June 2016 to November 2018 were included. The self-gripping mesh was placed in the sublay position. Demographic data, defect sizes, postoperative complications and follow-up durations were collected. A systematic review of the available literature was conducted in January 2020 using main databases. A total of 37 patients (20/17M/F) were included in this study, and the mean age and body mass index (BMI) were 58 years and 27 kg/m2, respectively. Minor complications occurred in six patients. Long-term follow-up demonstrated recurrence in three patients. Regarding the review, five publications were considered relevant. The highest complication rate was 28.6%, and the recurrence rate varied from 0 to 5.1%. This is the first review of the literature regarding sublay IH repair using a self-gripping mesh. The low rates of postoperative complications and recurrence in our experience and those reported by most of the reviewed articles demonstrate that this is a safe and effective method for repairing IHs.

e-TEP Retromuscular Repair for Recurrent Incisional Hernias: Report of Three Cases

Introduction. Recurrent incisional hernias are difficult to treat. There are many factors involved in the recurrence, and due to extensive dissections, the planes are fused with adhesions, and we may need a new plane for dissection and placement of meshes. Case Report. We report here three cases of recurrent incisional hernias which were dealt by a relatively new method to laparoscopy: the enhanced view totally extraperitoneal repair (e-TEP) retromuscular technique. There were three patients: one after an open onlay repair of lower midline incision, another after an onlay mesh repair of a subcostal incision for open cholecystectomy followed by an intraperitoneal onlay mesh hernioplasty (IPOM) repair, and another after IPOM repair of epigastric hernia. They were treated with the abovementioned technique with satisfying short-term results. Conclusion. The e-TEP technique is a relatively new method of providing minimal access surgery to these patients utilizing the previously unaccessed retromuscular (Rives and/or preperitoneal) space for the repair of these recurrent incisional hernias.

Open Retromuscular Repair of Parastomal Hernias with Synthetic Mesh

Parastomal hernias (PHs) cause significant morbidity in patients with permanent ostomies, and several laparoscopic and open repair techniques have been described. We report our experience with open retromuscular repair of PHs using permanent synthetic mesh. A prospectively maintained database was retrospectively reviewed to identify patients undergoing PH repair. Primary outcomes are surgical site occurrence, surgical site infection (SSI), and hernia recurrence. Variables were analyzed using Pearson's χ2 test or Fisher's exact test. Values of P < 0.05 were considered significant. Forty-six patients underwent retromuscular PH repair with permanent synthetic mesh. There were 26 patients with colostomies and 20 with ileostomies. All the patients were repaired using a keyhole retromuscular technique and direct passage of stoma through mesh. Transversus abdominis release was performed in 65.2 per cent of cases. Permanent synthetic polypropylene mesh was used in all cases. Surgical site occurrence occurred in 47.8 per cent of patients, SSI in 17.4 per cent, and hernia recurrence in 21.7 per cent. Resiting the stoma yielded the highest rate of SSI (40%) compared with leaving the stoma in situ (11.8%) or rematuring the stoma (0%; P = 0.011). Open keyhole retromuscular PH repair of PH with permanent synthetic mesh is safe, effective, and durable.
