Buttressing Sutures at the Center of the Mesh May Reduce the Probability of Recurrence in Onlay Incisional Hernia Repair: A Single-Center Study

INTRODUCTION

An incisional hernia is a common complication after abdominal surgery. Mesh fixation and fascial closure are crucial aspects of repairing incisional hernias. The aim of this study is to investigate the effect of adding a buttressing suture in the center of the mesh in onlay incisional hernia repair on recurrence.

METHODS

This retrospective study analyzed 157 patients who underwent elective repair of incisional hernia at Tokat State Hospital between January 2013 and January 2020. The study examined age, gender, comorbidity, smoking, hernia type, defect size, operative time, follow-up time, recurrence, and chronic pain. The patients were divided into two groups based on the type of buttressing suture used: normal and buttressing suture. Recurrence was defined as the reappearance of a hernia at the site of a previous surgery.

RESULTS

The study included 126 patients, with 61 (48.4%) in the control group and 55 (51.6%) in the buttressing suture group. Ten patients reported recurrence, with eight (13.1%) in the control group and two (3.1%) in the buttressing suture group. The difference in recurrence between the groups was statistically significant (p=0.038). The control group had an operative time of 58.79±13.23 minutes, while the buttressing suture group had an operative time of 62.12±13.51 minutes. The statistical analysis did not reveal any significant difference between the two groups (p=0.091). Out of the patients with chronic pain, two (33%) were in the control group and four (66%) were in the buttressing suture group. The incidence of chronic pain did not differ significantly between the two groups (p=0.52).

CONCLUSION

 In incisional hernia repair, the use of buttressing sutures with mesh in incisional hernia repair resulted in decreased recurrence rates without increasing chronic pain or affecting operative time.

Comparative Study of Self-Gripping Mesh vs. Polypropylene Mesh in Lichtenstein's Open Inguinal Hernioplasty

Background Inguinal hernia is one of the most common conditions in India, and history has many repair techniques recorded in it. Postoperative pain still remains a problem despite tension-free hernioplasty being accepted as the gold standard. Increased duration of surgery not only exposes the patient to unwanted increased chances of mesh infection but also reduces the surgeon's productivity if continued persistently. In this study, the main aim was to compare the fixation techniques of polypropylene mesh vs. self-gripping mesh in inguinal hernia surgery in terms of duration of surgery, postoperative pain, seroma, recurrence, foreign body sensation, and wound infections. Methods It is a prospective, comparative, and quantitative study conducted at Sri Ramachandra Institute of Higher Education and Research in the Department of General Surgery. Patients presenting with inguinal hernia to the OPD were included in the study. The sampling technique used in this study is simple, convenient sampling. As a result, the calculation of the margin of error and confidence levels may be difficult. Nevertheless, the sample accurately represents the population. Patients were divided into two groups: the study group (25), patients undergoing hernioplasty with self-gripping mesh, and the control group (25), patients undergoing hernioplasty with polypropylene mesh using conventional suturing. The duration of surgery, postoperative pain, seroma, recurrence, foreign body sensation, and wound infections were compared and analyzed between the two groups. Results In this study, the duration of surgery was less than one hour for three patients (12%) in the control group (polypropylene), compared to 13 (52%) patients in the study group (self-gripping), which is statistically significant. The early postoperative pain on POD 0 was greater than 4 (visual analogue score) in 8 (32%) patients in the control group and two (8%) patients in the study group. There were no significant differences in chronic pain, recurrence rate, seroma rate, or wound infection between the two groups. Conclusions In our study, we conclude that self-gripping mesh is superior to polypropylene mesh in surgery of inguinal hernia in terms of shorter duration of surgery. There is also reduced pain in the immediate postoperative period though not statistically significant. There is no significant difference in both the groups in terms of seroma formation, wound infection, foreign body sensation, and recurrence.

Comparison of prolene and progrip meshes in inguinal hernia repair in terms of post-operative pain, limitation of movement and quality of life

Objectives

The study aimed to compare the techniques applying prolene mesh and progrip-self fixating mesh in terms of post-operative pain, limitation of movement and quality of life.

Material and Methods

The study was conducted from November 2014 to January 2016 in Department of Surgery, Manisa Celal Bayar University Hospital. The study recruited 50 male patients, aged 18 and over and was carried out as a double blinded procedure. Twenty-five patients were randomly selected to receive hernia repair by progrip self-fixating mesh and 25 patients were treated with hernia repair with suture fixation method by using prolene grafts, and patients' pain follow-up was performed with face-to-face or telephone interviews with VAS (Visual Analogue Scale) and return to daily routine activities were evaluated with SF-36 (Short Form-36) quality of life scale. Recurrent hernias and emergency cases were excluded.

Results

The pain scores were lower and a statistically significant difference was achieved in patients in whom progrip self-fixating mesh was used in the early postoperative period. Both methods gave statistically similar results in terms of pain and quality of life.

Conclusion

In the literature, there are some evidence that the repair applied with progrip self-fixating graft has more positive outcomes compared to the repairs applied with suture fixation. It is concluded that there is a need for longer follow-ups and larger series of cases in order to achieve a definite result.

Clinical outcomes and quality of life associated with the use of a biosynthetic mesh for complex ventral hernia repair: analysis of the "Italian Hernia Club" registry

With the development of newer meshes and approaches to hernia repair, it is currently difficult to evaluate their performances while considering the patients' perspective. The aim of the study was to assess the clinical outcomes and quality of life consequences of abdominal hernia repairs performed in Italy using Phasix and Phasix ST meshes through the analysis of real-world data to support the choice of new generation biosynthetic meshes. An observational, prospective, multicentre study was conducted in 10 Italian clinical centres from May 2015 to February 2018 and in 15 Italian clinical centres from March 2018 to May 2019. The evaluation focused on patients with VHWG grade II-III who underwent primary ventral hernia repair or incisional hernia intervention with a follow-up of at least 18 months. Primary endpoints included complications' rates, and secondary outcomes focused on patient quality of life as measured by the EuroQol questionnaire. Seventy-five patients were analysed. The main complications were: 1.3% infected mesh removal, 4.0% superficial infection requiring procedural intervention, 0% deep/organ infection, 8.0% recurrence, 5.3% reintervention, and 6.7% drained seroma. The mean quality of life utility values ranged from 0.768 (baseline) to 0.967 (36 months). To date, Phasix meshes have proven to be suitable prostheses in preventing recurrence, with promising outcomes in terms of early and late complications and in improving patient quality of life.

The use of prosthetic mesh for abdominal wall repairs: A semi-systematic-literature review

Following abdominal wall surgery, incisions are commonly sutured, stapled, or glued together by primary intention. Developments within the field of tissue engineering have led to the use of prosthetic meshes, with over 20 million meshes implanted each year worldwide. The function of the mesh is to hold together abdominal wall incisions and repair abdominal hernias. This has been demonstrated to be highly effective in some individuals; however, some patients have experienced postoperative complications, including dehiscence with further abdominal herniation (viscera protruding through the abdominal wall). Little is currently known about why these complications occur in a subset of patients who have had prosthetic mesh implants in abdominal wall repairs; therefore, this literature review examined existing studies identified via six electronic databases. A total of 463 studies were identified, of which 13 were included in this review. The results identified that the prosthetic mesh is highly successful in a large proportion of patients who have had a had a hernia repair in a range of locations; however, the prosthetic mesh has long-term complications, with rejection being observed in a subset of patients. The reason why the prosthetic is being rejected is still largely unknown, and therefore, further investigation needs to be carried out.

Herniorrafia inguinal convencional com tela autofixante versus videolaparoscópica totalmente extraperitoneal com tela de polipropileno: resultados no pós-operatório precoce

RESUMO Objetivo: avaliar o resultado no pós-operatório precoce do tratamento da hérnia inguinal pela técnica convencional com tela autofixante versus videolaparoscópica totalmente extraperitoneal com uso da tela de polipropileno. Foram comparados, sobretudo, dor, tempo cirúrgico e complicações precoces. Métodos: estudo prospectivo, de série de casos, realizado na Clínica Cirúrgica A, do Hospital Universitário Gaffrée e Guinle (HUGG), no qual 80 casos consecutivos foram estudados. Apenas pacientes com hérnia inguinal unilateral, não recidivada e operadas em caráter eletivo foram incluídas no estudo. Os pacientes foram divididos em dois grupos, de 40 pacientes cada; grupo AF (técnica convencional com uso de tela autofixante) e grupo VL (técnica videolaparoscópica com uso de tela de polipropileno). Os pacientes foram acompanhados até o 45º dia de pós-operatório. Resultados: dos 80 pacientes operados no estudo, 98,7% pertenciam ao sexo masculino e a maioria era portadora de hérnia inguinal direita indireta (Nyhus II). Não houve diferença entre os grupos estudados no que diz respeito à dor e tempo operatório. No entanto, ocorreram mais complicações (seroma e hematoma) no grupo da cirurgia aberta. Conclusão: as duas operações realizadas se mostraram factíveis, seguras e estão relacionadas à mínima dor pós operatório e a um baixo tempo cirúrgico.

Randomized trial comparing self gripping semi re-absorbable mesh (PROGRIP) with polypropylene mesh in open inguinal hernioplasty: the 6 years result

OBJECTIVES

The use of absorbable polylactic acid hook self-gripping polypropylene mesh in open inguinal hernia may potentially reduce operative time and enhance patient recovery. The objective of this randomized trial is to compare the outcomes following self-gripping mesh repair to polypropylene mesh secured with sutures in open inguinal hernioplasty.

METHOD

Eligible patients aged 18-80 years old, who had primary unilateral uncomplicated inguinal hernia, were randomized into either Polypropylene (PL) group or PROGRIP (PG) group just before the placement of mesh intra-operatively by computer generated code. The primary outcome was the time from mesh placement to end of operation, whereas secondary outcomes included the total operative time, amount of analgesic used, length of post-operative stay, seroma formation, chronic discomfort, chronic pain score and recurrence. The study has been registered in http://www.clinicaltrial.gov carrying an ID of NCT00960011. Patients were followed-up in outpatient clinic for up to 6 years after operation.

RESULTS

From March 2009 to April 2016, 45 patients were included. The mean age of PG group (n = 22) was 62.0 ± 15.7 years old while that of the PL group was 62.6 ± 4.9 years old (n = 23). There was no significant difference regarding the smoking habit, drinking habit, comorbidities, previous hernia operation and Nyhus type of hernia between the two groups. The size of defects, the time of groin dissection and the size of incision were similar. In the PG group, there was significant reduction in the time for mesh placement (11.8 ± 3.1 vs. 21.0 ± 6.2 min, p < 0.001) and total operative time (39.2 ± 9.8 vs. 47.7 ± 8.0 min, p = 0.003). There was one recurrence in PL group and nil in PG group. Although there was a significant difference in paresthesia between 2 groups after operation, the difference disappears with time and comparable from post-operative 1 year onwards. There was no difference in chronic pain, chronic discomfort, affect daily activities, palpable mesh demonstrated throughout the whole study period till 6 years after operation.

CONCLUSIONS

The use of polylactic acid self-gripping mesh in open inguinal hernia repair effectively reduces the operating time with comparable long-term surgical outcome with traditional polypropylene mesh.
