Übersicht und aktuelle Trends in der Narbenhernienchirurgie

Incisional hernias occur in 5-10% of patients who have undergone laparotomy and are associated with high morbidity and significant socioeconomic costs. Techniques for reinforcing and/or replacing the abdominal wall with alloplastic meshes have reduced the recurrence rate in comparison to suture techniques from about 40% to less than 10%. A number of mesh types and surgical repair procedures are available, namely the onlay, inlay, sublay, underlay, and intraperitoneal onlay mesh (IPOM) techniques. Evolving strategies include precise criteria for incorporating patient body type, risk factors for recurrence, hernia morphology, and the available biomaterials into the planning of the surgical approach. The authors herein present an overview of the current surgical trends, focusing on mesh reinforcement (sublay technique) and mesh replacement (IPOM technique). Additionally, they review a classification of incisional hernias that is self-explanatory, practicable in routine clinical practice, and based on the cornerstones of morphology, hernia size, and risk factors for recurrence. Evidence for the indications and limitations of the main surgical repair techniques are illustrated and discussed.     

Incisional hernia repair in Sweden 2002

Incisional hernia is a common problem after abdominal surgery. The complication and recurrence rates following the different repair techniques are a matter of great concern. Our aim was to study the results of incisional hernia repair in Sweden. A questionnaire was sent to all surgical departments in Sweden requesting data concerning incisional hernia repair performed during the year 2002. Eight hundred and sixty-nine incisional hernia repairs were reported from 40 hospitals. Specialist surgeons performed the repair in 782 (83.8%) patients. The incisional hernia was a recurrence in 148 (17.0%) patients. Thirty-three per cent of the hernias were subsequent to transverse, subcostal or muscle-splitting incisions or laparoscopic procedures. Suture repair was performed in 349 (40.2%) hernias. Onlay mesh repair was more common than a sublay technique. The rate of wound infection was 9.6% after suture repair and 8.1% after mesh repair. The recurrence rate was 29.1% with suture repair, 19.3% with onlay mesh repair, and 7.3% with sublay mesh repair. This survey revealed that there is room for improvement regarding the incisional hernia surgery in Sweden. Suture repair, with its unacceptable results, is common and mesh techniques employed may not be optimal. This study has led to the instigation of a national incisional hernia register.     

Umbilical hernia in adults

Background: There is no consensus on the best technique for the repair of umbilical hernia in adults. The role of laparoscopic hernioplasty of umbilical hernia remains controversial. This study was undertaken to compare the outcomes of open and laparoscopic onlay patch repair of umbilical hernia in adults. Methods: From January 1996 to December 2002, 102 patients underwent elective repair of umbilical hernia. Operative techniques included Mayo repair (n = 43), laparoscopic onlay Gore-Tex patch hernioplasty (n = 26), suture herniorrhaphy (n = 24), and mesh hernioplasty (n = 9). Results: Demographic features and risk factors were similar among the four groups. The operative time of laparoscopic hernioplasty (median, 66 min) was significantly longer than those for patients who underwent Mayo repair (60 min) or sutured herniorrhaphy (50 min) (p < 0.05). None of the patients who underwent laparoscopic patch repairs required conversion to open repair. The median pain score at rest on postoperative day 1 was significantly lower in patients who underwent laparoscopic repair compared to those who had Mayo repair. A significantly shorter hospital stay and a lower wound morbidity rate were also observed in patients who underwent laparoscopic repair. With a mean follow-up of 2 years, suture herniorrhaphy had a relatively high recurrence rate (8.7%), whereas no recurrence was documented for the other techniques. Conclusions: Laparoscopic onlay patch hernioplasty is a safe and efficacious technique for the repair of umbilical hernia. Compared to Mayo repair, the laparoscopic approach confers the advantages of reduced postoperative pain, shorter hospital stay, and a diminished morbidity rate.     

Prognosis factors in incisional hernia surgery: 25 years of experience

Background Incisional hernia underwent a change from conventional techniques to mesh implantation. The relevance of different factors, like operative technique, mesh material, and patient-related parameters concerning the outcome following mesh repair, are still under debate.Methods In a comparative retrospective study of 421 incisional hernia operations on 348 patients, we investigated 241 Mayo procedures and 180 mesh repairs over a 25-year period. In addition to the quality of life following mesh implantation, the prognostic relevance of demographic, preoperative and intraoperative parameters, surgical technique, mesh material, and the surgeons experience were analysed, both in a univariate and multivariate manner.Results With a mean follow-up of 9.7±8.8 years, the total recurrence rate following Mayo overlap was 37%, in contrast to 15% after mesh implantation (P=0.001). Mesh size was the only significant prognostic factor concerning quality of life following mesh implantation, and 86% of the patients with mesh repair were satisfied. The complication rate was determined significantly by patients risk factors, size of hernia, operative technique, and the surgeons experience, whereas the rate of recurrences was significantly influenced by the parameters obesity (BMI>25), size of hernia, and surgical experience. The recurrence rate decreased significantly with surgeons experience—a minimum of 16 mesh repairs led to a recurrence rate of less than 10%. Conclusions Only the mesh repair revealed acceptable recurrence rates with high patient comfort. From a surgical point of view, the most important prognostic factor following mesh repair is the surgeons experience.This paper was presented to the American Hernia Society Congress in Orlando, Fla., USA, on Feb. 26, 2004.     

Konventionelle Reparation der parastomalen Hernie

The reparation of parastomal hernias and their recurrence remain problematic although the implementation of mesh techniques has lowered recurrences rates. Conventional surgical techniques include suture repair, relocation of the stoma as well as diverse hernia repair procedures with mesh implantation. Suture repair has been abandoned due to its high recurrence rate. Simple relocation is not recommended because of high rates of recurrent parastomal hernias. Conventional hernia repair using mesh implants is classified according to the mesh position into epifascial (onlay), retromuscular (sublay) and intraperitoneal (IPOM) techniques. Furthermore, a combination of relocation with additional mesh enforcement is also possible. The value of the different mesh techniques and of new biological mesh prostheses must be evaluated in randomized controlled studies.     

Open alloplasty of postoperative ventral hernias

Early and long-term results of the open ventral postoperative hernia alloplasty in 118 patients have been analyzed. The onlay and sublay techniques of the hernioplasty have been employed. The frequency of complications, local status and quality of life were studied a year after the operation. The overall postoperative morbidity and recurrence rates were reliably less after the sublay mesh implantation. The method has also provided better quality of life and local status characteristics.     

Parastomale Hernienversorgung mit prothetischer Netzplastik

After stoma formation, parastomal hernia develops in 30–50% of patients, with one-third of these require operative correction. Recurrence rates are very high after suture repair of parastomal hernias or relocation of the stoma. Open or laparoscopic mesh repairs have resulted in much lower recurrence rates. Long-term follow-up of the various techniques for parastomal hernia repair is lacking, as are randomized trials. A prophylactic prosthetic mesh placed in a sublay position at the index operation has reduced the rate of parastomal hernia in randomized trials. A prophylactic mesh in an onlay position, a sublay position, and an intraperitoneal onlay position has also been associated with low herniation rates in non-randomized studies. Although several questions within this field still have to be answered, it seems obvious that use of a mesh represents a suitable measure for the prevention of parastomal hernia as well as parastomal hernia repair.     

A Randomised Prospective Study to Evaluate Preperitoneal Mesh Repair Versus Onlay Mesh Repair and Laparoscopic IPOM in Incisional Hernia Surgery

Incisional hernia remains a very common postoperative complication. These are encountered with an incidence of up to 20 % following laparotomy. These hernias enlarge over time, making the repair difficult, and serious complications like bowel obstruction, strangulation and enterocutaneous fistula can occur. Hence, elective repair is indicated to avoid these complications. Implantation of a prosthetic mesh is nowadays considered as the standard treatment due to low hernia recurrence. The most common mesh repair techniques used are the onlay repair, sublay repair and laparoscopic intraperitoneal onlay mesh (IPOM). However, it is still not clear which technique among the three is superior. A study consisting of 30 patients who underwent incisional hernia repair by onlay, laparoscopic and preperitoneal mesh repair with abdominoplasty was conducted in the Coimbatore Medical College and Hospital. Of the three groups, the preperitoneal repair with abdominoplasty was found to have better patient compliance and satisfaction with regard to occurrence of complications and appearance of the abdominal wall without laxity in a single sitting.     

Operative Therapie der Narbenhernie

Secondary ventral hernia or incisional hernia occurs in at least 20?% of cases after laparotomy and most patients are symptomatic. The pathogenesis of incisional hernia is believed to be based on a defect in collagen synthesis indicating the necessity of covering the whole original incision with a non-resorbable, macroporous mesh. These meshes can be used on top of the fascia (onlay), in a retromuscular fashion (sublay) or intraperitoneally (IPOM). The IPOM technique is the preferred procedure during laparoscopic repair of ventral hernias. The clear advantage of the laparoscopic approach is the dramatically reduced rate of wound complications, especially infections. Major defects of the abdominal wall require plastic reconstruction with the component separation technique in both anterior and posterior approaches. The component separation technique must be combined with retromuscular mesh augmentation enabling a recurrence rate of less than 10 % and an acceptable morbidity to be achieved.

Surgical treatment for giant incisional hernia: a qualitative systematic review

Introduction

Repair for giant incisional hernias is a challenge due to unacceptable high morbidity and recurrence rates. Several surgical techniques are available, but all are poorly documented. This systematic review was undertaken to evaluate the existing literature on repair for giant incisional hernia.

Methods

Literature was identified through a systematic search on PubMed, EMBASE, and CINAHL. We only included studies with clearly defined surgical techniques and defect size of at least 15 cm. The heterogeneity of the studies precluded a meta-analysis. The analysis was based on the premises of a systematic review of the literature.

Results

We identified 14 studies (1,198 patients) including one randomised trial. Studies were mainly small and retrospective and highly heterogenic regarding design, outcome, inclusion, and exclusion criteria. The overall morbidity rate was median 32 % with a wide range between studies of 4–100 %. The mortality ranged from 0 to 5 % (median 0 %) and recurrence rate ranged from 0 to 53 % (median 5 %). Study follow-up ranged from 15 to 97 months (median 36 months). Mesh repair should always be used for patients undergoing repair for a giant hernia, and the sublay position may have advantages over onlay positioning. To avoid tension, it may be advisable to use a mesh in combination with a component separation technique. Inlay positioning of the mesh and repair without a mesh should be avoided.

Conclusions

Evidence to optimise repair for giant hernias is weak due to the heterogeneity and the poor quality of studies. However, sublay positioning of the mesh perhaps in combination with a component separation technique may be advantageous compared with other surgical techniques for giant hernia repair. Giant hernia repair is a challenging surgical procedure and severely lack evidence-based research from high-quality, large-scaled randomised studies.

Management of parastomal hernias

Stoma formation is a common aspect of general, colorectal, urologic, and oncologic surgical practice. Unfortunately, hernia formation around an ostomy trephine occurs in up to 50% of ostomates. In an era of explosive progress in abdominal wall surgery, parastomal hernia repairs remain plagued with technical challenges, high recurrence rates, and peri-operative morbidity. There is little expert consensus on the ideal operation. Repair type (suture or mesh based), surgical approach (laparoscopic, robotic, hybrid, or open), mesh configuration (cruciate, keyhole, or Sugarbaker), mesh type (permanent synthetic, biologic, or bioabsorbable), mesh location (underlay, sublay, or onlay) vary based on local expertise and patient clinical factors. This article will summarize the current literature on the management of parastomal hernias and provide expert commentary on our preferred practices for parastomal hernia repair.     

Tension free hernioplasty in the treatment of recurrent inguinal hernia. Our experience

BACKGROUND: Despite the new surgical approach with "tension free" techniques, recurrent inguinal hernia repair remains a difficult surgical problem. METHODS: Personal experience in 61 cases of recurrent inguinal hernia is reported; in all patients a new hernioplasty with a "tension free" technique was performed. Medium follow-up of the study was 27 months (min 6 mm, max 56 mm); 3 recurrences were observed, 2 in Lichtenstein "plug" hernioplasty and 1 with the Trabucco technique. RESULTS: No recurrences were observed in Lichtenstein "mesh" hernioplasty group. CONCLUSIONS: Lichtenstein "mesh" hernioplasty can solve every anatomical situation in hernia recurrence and good results, with little or any complications, are achievable; "plug" technique is easier but recurrences in other sites of a weak inguinal wall are possible.     

Onlay ventral hernia repairs using porcine non-cross-linked dermal biologic mesh

Introduction

Ventral hernias are common and repair with mesh has been shown to reduce recurrence. However, synthetic mesh is associated with a risk of infection. Biologic mesh is an alternative that may be less susceptible to infection. Typically, the sublay position is preferred for mesh placement but this technique takes longer and has not been shown to have a lower recurrence rate than an onlay mesh. The aim of this study was to evaluate the outcome of complex ventral hernia repair using a porcine non-cross-linked biologic mesh onlay.

Methods

A retrospective chart review was performed of all patients that had a ventral hernia repair with biologic mesh from January 2009 to March 2012. The operative procedure in all patients was an open repair with primary fascial closure (if possible) with or without external oblique component separation and porcine biologic mesh onlay.

Results

There were 22 patients that had a ventral hernia repair, 19 primary and 3 recurrent. The majority were men, had hernia grade 3 or 4, and developed the hernia after an esophagectomy or gastrectomy for cancer. All but one had primary closure with a porcine biologic mesh onlay. One patient was bridged for loss of domain. A bilateral external oblique component separation was added in 16 patients (73 %). The median hospital stay was 7 days. There were two superficial wound infections, one with exposed mesh, but no patient required mesh removal. A seroma requiring intervention developed in 6 patients (27 %) and resolved with pig-tail drainage. At a median follow-up of 7 months, there has been no hernia recurrence apart from the patient that was bridged.

Conclusions

Porcine non-cross-linked biologic mesh overlay has excellent short-term results in patients at increased risk for mesh infection. No patient required mesh removal, and there have been no recurrent hernias in patients with primary fascial closure. Biologic bridging is not effective for long-term abdominal wall reconstruction.     

Kosten- und Risikoanalyse der Hernienreparation

In comparison to the conventional technique of incisional or umbilical hernia repair with sublay mesh augmentation, incisional hernias in obese patients can be surgically treated with minor surgical trauma by laparoscopic intraperitoneal onlay mesh (IPOM) repair. However, although shortened operation time, hospital stay and faster postoperative reconvalescence might be possible with IPOM repair, the economic calculation including mesh costs is significantly higher. In this study the two operation techniques were compared and the perioperative advantages and disadvantages of both methods were analyzed based on the German diagnosis-related groups (DRG) system.     

Results of ventral hernia repair: comparison of suture repair with mesh implantation (onlay vs sublay) using open and laparoscopic approach--prospective,randomized, multicenter study

Incisional hernias is a frequent complication following abdominal surgery, it develops in 11-20% of patients who had laparotomies. Different operative techniques are used for repair but results are often poor. In the absence of valid scientific data, there is no general agreement on the best surgical treatment. To provide evidence based surgery a nation-wide multi-center, prospective, randomized study is set up. The present study compares suture and mesh repairs in different positions, using open and laparoscopic approach to define standard indication for the treatment of incisional hernias. The study was started in March, 2002, with 23 surgical departments participating. Each report about 100 patients with incisional hernia repair. The 2300 consecutive patients (who are 18 to 70 years old) with primary incisional hernia or first recurrent umbilical hernia are randomized. Patients are divided in two groups. If the hernia is between 5-25 cm2 (Group I) they are selected at random either for prosthetic (sublay) or suture repair. In patients with a hernia larger than 25 cm2 (Group II) mesh is implanted at random as either sublay or onlay position using a computer randomization program. After a short learning period, in Group II the laparoscopic approach will also be randomized. Postoperative outcome, complications and recurrence are recorded. The study will run for five years. All collected data are sent to the coordinating center via internet to be entered into database.     

不同补片放置层次治疗外科手术切口疝的疗效

目的对不同补片放置层次（肌后修补术与腹腔内修补术）治疗外科手术切口疝的疗效及并发症发生情况进行比较。 方法回顾分析2015年1月至2018年1月,江苏省宜兴市人民医院普外科收治的切口疝72例患者的临床资料,其中采用腹腔内修补术35例（腹腔组）,肌后修补术37例（肌后组）,观察2组手术基本情况（手术时间、术后住院时间、住院总费用、术中出血量）、并发症（肠管损伤、肠梗阻、肠瘘、切口感染、切口脂肪液化）;术后第1天、第3天疼痛视觉模拟评分（VAS）及随访1年的复发情况。 结果腹腔组手术时间、术后住院时间均较肌后组短,而腹腔组术中出血量低于肌后组,但腹腔组住院总费用高于肌后组,差异有统计学意义（P<0.05）;腹腔组肠管损伤、肠梗阻、切口感染及切口脂肪液化等发生率低于肌后组,腹腔组见1例（2.86%）肠瘘并发症,肌后组未有肠瘘并发症出现,2组组间差异无统计学意义（P>0.05）;2组患者术后第1天、术后第3天VAS评分比较,差异无统计学意义（P>0.05）;随访1年后腹腔组复发0例,肌后组在术后7个月时有2例（5.71%）复发,2组复发率无统计学意义（P>0.05）。 结论两种术式不同补片放置层次方法治疗切口疝均有效,但腹腔内修补术治疗效果更佳,安全性高。     

Incisional hernia repair after orthotopic liver transplantation: a technique employing an inlay/onlay polypropylene mesh

Background: The literature provides no data on the incidence and operative management of incisional hernias developing after orthotopic liver transplantation. The use of high-dose immunosuppressive agents results in an appreciable delay in wound healing. There is thus a need for a procedure for the reconstruction of the abdominal wall for patients on immunosuppression. The aim of this retrospective study was to establish the incidence of incisional hernias and an analysis of the results after implantation of a polypropylene mesh in inlay–onlay technique after liver transplantation is given.Methods: The basis for the present retrospective investigations was a total of 207 liver transplantations carried out in 192 patients (15 re-transplantations). After performing tensiometry, a polypropylene mesh (Marlex) was implanted to close the hernias using the inlay/onlay technique or a direct closure of the fascia was done. All treated hernias were followed up for a median of 18 months.Results: Among 184 patients, 17 developed incisional hernias after primary direct closure of the abdominal wall, giving an incidence of 9%. In an additional 8 patients an incisional hernia was seen where an absorbable mesh was used to close the abdominal wall after liver transplantation. In addition, there were 25 incisional hernias after 207 liver transplantations (12%). One of 15 (7%) of the surgically repaired hernias with implantation of a polypropylene mesh (Marlex) developed a recurrence. All the 3 patients after direct apposition of the fascia without using a polypropylene mesh suffered a recurrence (3 of 3; 100%). Significant risk factors for developing an incisional hernia were the amount of ascites and the stay in the ICU after transplantation. Neither severe deep nor superficial wound infection nor bowel fistulas were observed after implantation of a inlay/onlay mesh.Conclusion: In patients after liver transplantation, the implantation of a polypropylene mesh proved to be an efficient and safe method of treating incisional hernias. Implantation of a mesh was not associated with an increased infection rate, despite the use of immunosuppression. In view of the high recurrence rate associated with primary closure, mesh implantation should be given preference.
