Hernia

Mesh fixation in open IPOM procedure with tackers or sutures? A randomized clinical trial with preliminary results

Abstract

Purpose

In open intra-peritoneal onlay mesh (IPOM) hernia repair, mesh fixation can be done by tacks, sutures or fibrin glue. There are randomized controlled trials (RCTs) on laparoscopic IPOM procedure, but no RCT so far has examined mesh fixation techniques in open IPOM repair.

Methods

In a single-center RCT, 48 patients undergoing open IPOM repair of an abdominal wall hernia were included. After randomization, surgery was performed in a standardized fashion. Hernia size, extent of mesh fixation, and duration of surgery were documented. The primary endpoint was postoperative pain intensity. Secondary endpoints were: complications, length of stay, quality of life, return to work, hernia recurrence. Follow-up was 1 year in all 48 patients.

Results

After using tacks, mean pain intensity was 16.9, which is slightly lower than after suture fixation (19.6, p = 0.20). The duration of surgery was about the same (83 vs. 85 min). When using tack fixation, significantly more fixation points were applied as compared to sutures (19 vs. 12; p = 0.02), although mesh size was similar. The complication rate was similar (tacks: 6/28 vs. sutures: 3/20). Cost of suture fixation was about 26 €, which is markedly lower than the 180 € associated with tacks. However, surgeons clearly preferred mesh fixation with tacks, because it is more comfortable especially in small hernias.

Conclusions

The present study failed to show an advantage of tacks over suture fixation and even there are more severe adverse events. Using tacks significantly increases the costs of hernia repair.



Individual mesh size for open anterior inguinal hernia repair: an anthropometric study in Turkish male patients

Abstract

Purpose

To conduct a study to determine the measurements of the inguinal region in male patients with inguinal hernias to reveal the proper mesh size for each patient.

Methods

In this prospective study, the anthropometric measurements were obtained from 100 consecutive adult male patients with unilateral primary inguinal hernias. First, the distance between the pubic tubercle and the medial border of the deep inguinal ring was measured (x). Second, the distance between the inner edge of the inguinal ligament and the uppermost level of the internal oblique aponeurosis at the midpoint of the inguinal ligament corresponding to the Hesselbach triangle was measured (y). Individual mesh sizes were calculated according to the original recommendations for mesh overlap.

Results

The mean x value was 41.6 mm (22–55 mm), the mean y value was 45.2 mm (30–68 mm). The mean dimensions of the mesh were 126.6 mm × 65.2 mm. The largest mesh was 140 mm × 88 mm, and the smallest one was 107 mm × 62 mm. The mean mesh area was 8320 mm2. It was larger than the index mesh area recommended by the Lichtenstein Hernia Institute in 45 patients and smaller in 55 patients.

Conclusions

The intraoperative measurements for ideal mesh size in Lichtenstein repair of inguinal hernias may present somewhat different mesh dimensions in many patients. Individualization of mesh size may be of importance in surgical outcomes.



New, simple and reliable volumetric calculation technique in incisional hernias with loss of domain

Abstract

Introduction

The management of hernias with loss of domain is a challenging problem. It has been shown that the volume of the incisional hernia/peritoneal volume ratio < 20% was a predictive factor for tension-free fascia closure, after pre-operative pneumoperitoneum preparation (Goni Moreno technique). In this study, we propose an easy, reliable and fast technique to perform volumetric calculation, by the surgeon alone.

Materials and methods

3D slicer software (free open-source software) was used to calculate with precision the intra-peritoneal and intra-hernia volumes, and to create a 3D reconstruction of both volumes. The measurement technique is described step by step using detailed figures and videos.

Results

The method was used to calculate the volumes for five consecutive patients, managed between January 2018 and March 2019. All the five patients had a ratio greater than 20% and, therefore, received a PPP program. The effectiveness of the procedure is objectified by the increase of the intraabdominal volume and the reduction of the incisional hernia/peritoneal volume ratio. The feasibility of a tension-free fascia closure was confirmed for the five patients.

Conclusion

In addition to a standardized definition of "loss of domain", a standardized volumetric technique, easy to reproduce, needs to be adopted. Our method can be done by any surgeon with basic computer skills and radiological knowledge in an autonomous and a fast manner, thus helping to select the right technique for the right patient.



Study of mesh infection management following inguinal hernioplasty with an analysis of risk factors: a 10-year experience

Abstract

Purpose

We present a review of our 10-year experience in managing patients with mesh infection following hernioplasty and analyze the occurrence of known predisposing factors.

Methods

We analyzed 392 cases of mesh infection treated at our center between 2007 and 2018 after a preoperative work-up. (Thirty-one patients underwent the primary hernia repair procedure at our hospital, whereas the others underwent the primary surgery at other local centers and were referred to our center.) The method of infected mesh removal (open or laparoscopic) was selected depending on the primary surgical approach. Open repair involved the excision of the mesh, infected tissue, and sinus (if present). The laparoscopic approach was used to identify the abscess, excise the mesh, and allow drainage into the preperitoneal space.

Results

The operative course in all patients was uneventful. A second surgery to extract the residual mesh around the pubic bone was performed in 7 patients. Hernia recurred in 29 patients after mesh removal. The discharge culture results were positive in 193 patients. Of these, Staphylococcus spp. was identified as the causative organism in 126 patients. Risk factors for mesh infection, including obesity, smoking, and diabetes, were identified in 182 (46.5%), 154 (39.3%), and 35 (8.9%) patients, respectively.

Conclusions

It is recommended the approach of mesh removal is tailored as per the primary hernioplasty method. We analyzed the occurrence of risk factors for mesh infection in this study, but further studies are needed to develop a predictive model that is both internally and externally validated to evaluate the probability of mesh infection.



Enhanced recovery after surgical repair of incisional hernias

Abstract

Aim

Enhanced recovery programmes (ERPs) were developed to improve the patient's post-operative comfort and reduce post-operative morbidity after several types of major surgery including the incisional hernia repair. The aim of this review was to describe the features of ERPs in the setting for incisional hernia repair.

Methods

The literature review was conducted until March 2019, but retrieved very few papers (n = 4) on this topic. All studies were retrospective.

Results

Setting and comorbidities of incisional hernia patients are of such importance in many cases that prehabilitation (including tobacco use cessation, management of obesity, diabetes or malnutrition) should play a greater role compared with other specialties. The other peri-operative measures are similar to other specialties but their implementation was very heterogeneous in the published studies.

Conclusions

Like in other surgeries, ERPs were feasible and probably efficient to improve the post-operative course of incisional hernia patients. But the level of evidence remains low.



Contribution of heparin to recovery of incarcerated intestine in a rat incarcerated hernia model

Abstract

Purpose

Inguinal hernias are the most common type of abdominal wall hernias. Although surgery is the only effective treatment for these hernias in adults, several problems associated with surgical treatment have been reported. If the hernia exits from a weak point of the abdominal wall, it can obstruct the bowel, thereby causing serious complications, including intestinal obstruction or strangulation. Through this study, we aimed to analyze the optimal incarceration induction time taken to cause some degree of necrosis from which recovery would be possible in a rat incarcerated abdominal wall hernia model and to determine the efficacy of heparin for expedite recovery from intestinal incarceration.

Methods

A rat incarcerated abdominal wall hernia model was constructed, intestinal activity and the incarceration induction time were determined based on the color of the intestine and HE staining of intestinal sections. Heparin and procaine were sprayed onto intestinal surfaces, and their effects on the recovery from intestinal incarceration were evaluated.

Results

Recovery from intestinal incarceration would be better if the incarceration induction time was maintained below 2.5 h in our rat model, and heparin was found to be superior to procaine in the expedite recovery from intestinal incarceration, particularly immediately after relieving such intestines.

Conclusions

The results of this study are significant for planning the treatment of incarcerated inguinal hernia. Further, heparin is superior to procaine in terms of expedite recovery from intestinal incarceration.
