Laparoscopic versus open ventral hernia mesh repair: a prospective study

Background An incisional hernia develops in 3% to 13% of laparotomy incisions, with primary suture repair of ventral hernias yielding unsatisfactory results. The introduction of a prosthetic mesh to ensure abdominal wall strength without tension has decreased the recurrence rate, but open repair requires significant soft tissue dissection in tissues that are already of poor quality as well as flap creation, increasing complication rates and affecting the recurrence rate. A minimally invasive approach was applied to the repair pf ventral hernias, with the expectation of earlier recovery, fewer postoperative complications, and decreased recurrence rates. This prospective study was performed to objectively analyze and compare the outcomes after open and laparoscopic ventral hernia repair. Methods The outcomes for 50 unselected patients who underwent laparoscopic ventral hernia repair were compared with those for 50 consecutive unselected patients who underwent open repair. The open surgical operations were performed by the Rives and Stoppa technique using prosthetic mesh, whereas the laparoscopic repairs were performed using the intraperitoneal onlay mesh (IPOM) repair technique in all cases. Results The study group consisted of 100 patients (82 women and 18 men) with a mean age of 55.25 years (range, 30–83 years). The patients in the two groups were comparable at baseline in terms of sex, presenting complaints, and comorbid conditions. The patients in laparoscopic group had larger defects (93.96 vs 55.88 cm²; p = 0.0023). The mean follow-up time was 20.8 months (95% confidence interval [CI], 18.5640–23.0227 months). The mean surgery durations were 90.6 min for the laparoscopic repair and 93.3 min for the open repair (p = 0.769, nonsignificant difference). The mean postoperative stay was shorter for the laparoscopic group than for the open hernia group (2.7 vs 4.7 days; p = 0.044). The pain scores were similar in the two groups at 24 and 48 h, but significantly less at 72 h in the laparoscopic group (mean visual analog scale score, 2.9412 vs 4.1702; p = 0.001). There were fewer complications (24%) and recurrences (2%) among the patients who underwent laparoscopic repair than among those who had open repair (30% and 10%, respectively). Conclusions The findings demonstrate that laparoscopic ventral hernia repair in our experience was safe and resulted in shorter operative time, fewer complications, shorter hospital stays, and less recurrence. Hence, it should be considered as the procedure of choice for ventral hernia repair.     

Incisional hernia—comparison of mesh repair with Cardiff repair: an university hospital experience

Background: Incisional hernia is a frequent complication of abdominal surgery. Various types of repair are recommended for incisional hernia. Suture and mesh repair are compared in the present study. Method: One hundred seventy one patients with incisional hernia underwent Cardiff repair (far and near sutures with reinforcement sutures) which was used as an open suture repair while onlay polypropylene mesh was used in the mesh repair technique. Result: Cardiff repair was performed in 116 patients with no mortality with recurrence in two patients with mean follow up of 7.1 years. Both these patients with recurrence had a defect measuring more than 10 cm in width. Mesh repair was carried out in 55 patients with no recurrence in mean follow up of 37 months. Seroma formation was noted in 7 (12.72%) with mesh repair as compared to 4 (3.44%) patients with Cardiff repair. Conclusion: We recommend Cardiff repair for primary and small to medium size incisional hernias. Onlay polypropylene mesh is ideal for tension-free hernia repair, recurrent incisional hernia and hernia defects wider than 10 cm.     

腹腔镜下腹壁疝腹膜外补片修补术与腹腔内补片修补术比较的多中心回顾性研究

背景与目的 腹壁疝修补术是最常见的外科手术之一,全球每年有200万例左右的腹壁疝患者接受手术治疗。与开放手术相比,腹腔镜下腹壁疝修补术优势明显。然而腹腔镜下腹腔内补片修补术（IPOM）与腹腔镜下腹膜外补片修补术（ESR）这两种腔镜术式的优缺点及疗效如何,尚无大样本的临床研究证实。因此,本研究通过比较ESR与IPOM两种手术方式治疗腹壁疝的近远期疗效,为临床提供循证参考。方法 回顾性分析2017年1月1日—2022年12月31日湖南省11家医疗机构收治的157例行腹腔镜腹壁疝修补术患者的临床资料,其中124例行ESR（ESR组）,33例行IPOM（IPOM组）,对比分析两组病例的临床特点、手术方式和术后近远期效果。结果 全组无中转开腹病例或围术期死亡病例。两组病例的年龄、性别、BMI、类型差异均无统计学意义（均P>0.05）。两组病例疝环横径、手术时间、术中出血量、疝环闭合概率差异均无统计学意义（均P>0.05）。网片固定方式ESR组以自固定和缝线固定为主（91.1%）,而IPOM组以钉枪固定为主（69.7%）,差异有统计学意义（P<0.05）。ESR组的术后疼痛评分明显低于IPOM组（2.4±0.8 vs. 2.8±1.0,P<0.05）,住院费用明显低于IPOM组（21 001元vs. 38 437元,P<0.05）。两组的术后住院时间和近期并发症发生率差异无统计学意义（均P>0.05）。中位随访10.3个月,ESR组无复发病例,IPOM组2例复发（6.1%）,差异有统计学意义（P<0.05）。结论 ESR是湖南地区腹腔镜下腹壁疝修补的主流术式之一。由于固定方式和网片选择的不同,ESR较之IPOM而言,术后疼痛更轻微、费用更低、复发率更低,且并不明显增加手术时间和术后近期并发症。     

Outcomes following repair of incarcerated and strangulated ventral hernias with or without synthetic mesh

Background

The use of synthetic mesh for ventral hernia repair under contaminated conditions is a controversial issue due to the considerable risk of surgical site infection (SSI). This study aimed to review the outcomes of repair of incarcerated and strangulated ventral hernias with or without synthetic mesh in compliance with established clinical guidelines regarding the incidence of SSI and hernia recurrence.

Methods

The records of patients with complicated ventral hernias who were treated with or without synthetic mesh repair were reviewed. Variables collected included the characteristics of patients and of ventral hernias, type of repair, and incidence of SSI and recurrence.

Results

One hundred twenty-two patients (56 males) of a mean age of 56 years were included. Fifty-two (42.6%) and 70 (57.4%) patients presented with incarcerated and strangulated ventral hernias, respectively. Sixty-six (54%) patients were treated with on-lay mesh repair, and 56 (46%) were managed with suture repair. Twenty-one patients required bowel resection. SSI was detected in eight (6.5%) patients. There was no significant difference between both groups regarding the incidence of SSI (7.5% for mesh group vs 5.3% for suture group). Recurrence occurred in seven patients. Median follow-up period was 24 months. The suture repair group had a significantly higher incidence of recurrence than the mesh group. Diabetes mellitus, previous recurrence, and intestinal resection were significant predictors for SSI.

Conclusion

Following established guidelines, synthetic mesh repair of incarcerated and strangulated ventral hernias attained lower recurrence rate, comparable incidence of SSI, and higher rate of seroma formation than suture repair.

Open intraperitoneal versus retromuscular mesh repair for umbilical hernias less than 3cm diameter

Background

Mesh techniques are the preferable methods for repair of small ventral hernias, as a primary suture repair shows high recurrence rates. The aim of this prospective study was to compare the retromuscular sublay technique with the intraperitoneal underlay technique for primary umbilical hernias.

Methods

From February 2004 to April 2007, all patients treated for umbilical hernias with maximum diameters of 3 cm were prospectively followed. During the first period of 15 months, all patients were treated with retromuscular repair using a large pore mesh (Vypro). After that period, for all patients, mesh repair using an intraperitoneal Ventralex patch was performed. All patients underwent general anesthesia. This analysis included 116 patients, of whom 56 had retromuscular repair (group I; mean age, 54.8 years; mean body mass index, 28.2 kg/m²) and 60 had open intraperitoneal repair (group II; mean age, 48.1 years; mean body mass index, 29.4 kg/m²). Operating time was evaluated as skin-to-skin time, and drain management was noted for both techniques. Follow-up was ≥2 years for all patients, and both early and late complications were registered, including seroma and hematoma formation, wound infection, fistula formation, and recurrence rates. Preoperative and postoperative pain was evaluated using a visual analogue scale (range, 0–10) on the day of the first outpatient visit; on postoperative days 1, 7, and 21; and after 1 year. Quality of life was estimated using the EQ-5D questionnaire 1 year after surgery. All data were analyzed using SPSS version 15 software. Wilcoxon's rank-sum test was used to analyze continuous variables, and repeated-measures analysis of variance was used for visual analogue scale scores. The χ² test and Fisher's exact test were used to assess the differences between categorical data. P values < .05 were considered statistically significant.

Results

The mean operative times were 79.9 minutes in group I and 33.9 minutes in group II (P < .001). The mean hospital stay was significantly longer in group I (3.8 vs 2.1 days, P < .001). Seromas and superficial wound infections in the early postoperative period were not different between both groups, although seromas occurred more frequent in the retromuscular group. Postoperative visual analogue scale scores were significantly lower with the intraperitoneal technique at all time points (P < .003, repeated-measures analysis of variance). However, 3 patients with the Ventralex patch had to be readmitted for severe pain. The recurrence rate was higher with the intraperitoneal repair (n = 5 [8.3%] vs n = 2 [3.6%]) than for the retromuscular mesh repair, but not statistically significant. Quality of life was comparable in the two groups after 1 year.

Conclusions

The open intraperitoneal technique using a Ventralex mesh for umbilical hernias seems a very elegant and quick technique. However, possibly because of the less controllable mesh deployment, recurrence rates seem higher. In case open mesh repair is the preferred treatment, a retromuscular repair should be the first choice.     

Use of polypropylene mesh for incisional hernia repair

Incisional hernia is an important complication of abdominal surgery. Procedures for the repair of these hernias with sutures and with mesh have been reported, but there is no consensus about which type of procedure is best. We have performed a retrospective analysis on 1014 patients operated on in our unit between 1994 and 2003 for simple or recurrent incisional hernias. The polypropylene mesh has been used in a number of 107 patients. The mesh has been placed either intraperitoneal, extraperitoneal/subfascial or onlay. Median follow-up was 36 months. There were 1 enterocutaneous fistula and 5 wound sinus developed. The mesh had to be removed in 6 cases. All of these complication developed when the mesh has been placed either extraperitoneal/subfascial or onlay. We note 5 recurrent incisional hernias after a period of up to 24 months. The recurrence rates after open mesh repair are less then after primary closure. The intraperitoneal use of polypropylene mesh with omental coverage is a good procedure with less complications.     

Intraperitoneal modification of the Rives-Stoppa repair for large incisional hernias

Introduction Recurrence rates for open repair of ventral/incisonal hernias historically range from 6% for the classic Rives-Stoppa repair to 35–45% for some of the techniques more commonly used in the United States. We report a modification to the classic Rives-Stoppa repair that allows intraperitoneal placement of the prosthetic, secured with a running suture. The abdominal muscles are closed over the mesh to protect it from any superficial wound problems that might develop and to restore normal architecture of the abdominal wall. Method A chart review was undertaken on all patients undergoing open ventral incisional hernia repair by a single surgeon from 2000 to 2006. All hernias were repaired with the intraperitoneal modification mimicking the principles of the Rives-Stoppa repair. Patient characteristics and operative and postoperative data were collected. Primary outcome was recurrence of hernia. Secondary outcomes were complications and rate of mesh infection. Results One hundred and fifteen patients were evaluated. Thirty-four patients had repair of recurrent ventral hernias. The average patient was obese, female, and 59 years old. Twenty-five patients used tobacco, eleven were diabetic, and seven used chronic corticosteroids. Meshes utilized included ePTFE, coated polyester, coated polypropylene, and biologic mesh. Average size of mesh was 465.4 cm². There were four recurrences (3.4%), three of which were due to mesh infection requiring mesh removal. Recurrence rate not secondary to mesh removal was 0.9%. Complications occurred in 26% with seroma formation being the most frequent (16%). Conclusion The intraperitoneal modification to the original Rives-Stoppa repair leads to a very low recurrence rate for large ventral hernia repairs with minimal complications and low rate of mesh infection.

Laparoscopic intraperitoneal polytetrafluoroethylene (PTFE) prosthetic patch repair of ventral hernia

Background: The purpose of this study was to determine whether laparoscopic intraperitoneal polytetrafluoroethylene (PTFE) prosthetic patch (LIPP) repair of a ventral hernia is superior to open prefascial polypropylene mesh (OPPM) repair in a tertiary care university hospital in an urban environment. Methods: Data on 39 consecutive patients undergoing either LIPP repair (n= 21) or OPPM repair (n= 18) were compared. Results: Findings showed that LIPP repair is characterized by less painful recovery and shorter hospital stay, with 90% of patients treated successfully as outpatients as compared with 7% in the OPPM group. The total facility costs for the LIPP repair ($8,273 ± $2,950) was significantly lower than for the OPPM repair ($12,461 ± $5,987) (p < 0.05). Two serious delayed complications in the LIPP group were treated by reoperation (colocutaneous fistula, mesh infection), but the higher readmission costs in this group did not negate the overall cost advantage for LIPP repair. In the follow-up evaluation, 1 hernia recurrence was found in the LIPP repair group, and none in the OPPM group. Conclusions: Initial experience suggests that LIPP repair has advantages over OPPM repair in terms of decreased hospitalization, postoperative pain, and disability. Refinements in the technique to reduce complications may make LIPP repair the procedure of choice for repair of ventral hernias. Received: 5 June 1998/Accepted: 15 October 1999     

Laparoscopic ventral hernia repair with extraperitoneal mesh: surgical technique and early results

Laparoscopic repair of ventral abdominal wall hernias involves intraperitoneal placement of a mesh, which may lead to adhesion formation and bowel fistulation. The first series of selected patients with ventral abdominal wall hernias treated laparoscopically by extraperitoneal placement of a polypropylene mesh is presented. Thirty-four patients (24 women and 10 men; median age, 52 years [range, 34-70]) were selected from among 122 patients undergoing laparoscopic ventral hernia repair. Of these patients, 18 had a primary ventral abdominal wall hernia and 16 had an incisional hernia. After reduction of sac contents and adhesiolysis intraperitoneally, a large flap of peritoneum (with extraperitoneal fat, fascia, and posterior rectus sheath where present) was raised to accommodate a suitably sized polypropylene mesh, which was then covered again with the peritoneal flap at the end of the procedure. Intraoperatively, apart from circumcision of the hernial sac at the neck, a total of 24 iatrogenic peritoneal tears occurred in 20 patients, mainly at the site of the previous scar. In two patients, it was observed that greater than 25% of the mesh was exposed after the procedure. The median (+/-SD) duration of hospitalization postoperatively was 1 day (+/-0.56). One patient's hernia recurred 4 months after surgery, and one patient's infected mesh was removed 8 months after surgery. Laparoscopic extraperitoneal placement of a mesh is feasible and appears to be an advance over laparoscopic intraperitoneal mesh placement for ventral abdominal wall hernias in selected patients. However, longer follow-up and controlled clinical trials will be necessary before any firm conclusions can be drawn.     

Open versus laparoscopic intraperitoneal on-lay mesh repair: A comparison of outcomes in small ventral hernia

PurposeThe ideal surgical treatment of small ventral hernias (defect less than 4 cm) is still debatable. In our study, we sought to compare the outcomes of open versus laparoscopic intraperitoneal on-lay mesh (IPOM) repair in small ventral hernias.MethodsPatients with a single ventral hernia defect of less than 4 cm undergoing surgical mesh repair between January 2016 and September 2018 were prospectively registered for this study. The minimum follow-up duration was 12 months. Patient demographics, operative findings and regular post-operative follow-up details including recurrence rates and complications were recorded and analysed.Results41 patients underwent laparoscopic IPOM repair and 47 patients underwent open IPOM repair. The mean age for both groups is similar with no significant difference. The mean hernia defect size for the laparoscopic group is 2.8 cm (±0.8) whereas the mean hernia defect size for the open repair group is 2.1 cm (±0.4). The mean surgery duration for open IPOM repair was significantly shorter (59 min (±17) vs 74 min (±26); p = 0.001). There was no significant difference in the incidence of seroma formation and surgical site infections post-operatively. There was also no significant difference in both groups in terms of chronic pain and recurrence at 1-year follow-up.ConclusionOpen IPOM repair for small ventral hernias may be superior to laparoscopic IPOM repair due to the shorter operative duration, single incision, and no additional risk of port-site hernias. There was no difference in chronic pain, wound infection and recurrence rate between the two groups.     

Two cases of cystic seroma following mesh incisional hernia repair

Cystic seromas, or mature fibrous cysts, are rare complications after ventral and incisional hernioplasties employing polypropylene mesh. We analyzed the medical records of patients, whose abdominal-wall hernias were surgically repaired with polypropylene mesh from November 1996 to February 2004 (N=685). Of the 162 patients, who had incisional hernias repaired with the Rives technique (preperitoneal mesh), we detected two patients who developed giant cystic seromas. Both patients underwent surgical resection of the cyst wall. As follow-up care improves for patients undergoing hernioplasties with polypropylene meshes, more cystic seromas are detected, thereby improving our knowledge of the clinical, radiological, and histopathological characteristics of this complication. However, the etiologic factors related to the appearance of this chronic cyst remain uncertain.     

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.     

Closure versus non-closure of hernia defect during laparoscopic ventral hernia repair with mesh

Purpose

Laparoscopic ventral hernia repair with mesh versus laparoscopic ventral hernia defect closure with mesh reinforcement. The primary end-point was recurrence.

Methods

Retrospective review of patients who underwent laparoscopic ventral hernia repair for small- and medium-sized hernias between July 2000 and September 2011. These patients were divided: (1) repair with mesh alone (non-closure group) and (2) those with hernia defect closure and mesh reinforcement (closure group). The closure group was further divided by technique: percutaneous versus intracorporeal closure of the defect.

Results

128 patients were studied: 93 patients (72.66 %) in the non-closure group and 35 patients (27.34 %) in the closure group. Follow-up was available in 105 patients (82.03 %) at a mean of 797.2 days (range 7–3,286 days). In the non-closure group there were 14 patients (15.05 %) with postoperative complications and 8 patients (22.86 %) in the closure group, four of which were seromas. Fourteen patients (19.18 %) developed recurrent hernias in the non-closure group with an average time to presentation of 23.17 months (range 5.3–75.3). Two patients (6.25 %) developed recurrent hernias in the percutaneous group with an average time to presentation of 12.95 months (range 9.57–16.33). There have been no recurrences in patients whose defect was closed intracorporeally.

Conclusion

Although our study demonstrated a difference in recurrence rates of 19.18 % in the non-closure group versus 6.25 % in the closure group, the difference did not reach statistical significance. A larger series with longer follow-up may demonstrate clinical significance.     

Adhesion formation after laparoscopic ventral incisional hernia repair with polypropylene mesh: a study using abdominal ultrasound.

OBJECTIVE: Laparoscopic repair of ventral incisional hernias is feasible and safe. Polypropylene mesh is often preferred because of its ease of handling and lower cost. Complications like adhesion and fistula formation can occur. The goal of this study was to determine whether bowel adhesions and their attendant complications could be prevented by interposition of omentum. METHODS: Thirty patients underwent laparoscopic ventral incisional hernias repair with polypropylene mesh. Omentum was always positioned over the loops of bowel for protection. At a mean follow-up of 14 months, 20 patients underwent ultrasonic examination using the previously described visceral slide technique to detect adhesions. RESULTS: The mean size of the hernias in the study was 50.3 cm2, and the mean size of the mesh applied was 275 cm2. Thirteen patents (65%) had no sonographically detectable adhesions. Five patients demonstrated adhesions between the mesh and omentum, 1 patient developed adhesions between the left lobe of the liver and the mesh, and only 1 case of bowel adhesion to the edge of the mesh was found. CONCLUSION: Laparoscopic ventral incisional hernias repair with polypropylene mesh and omental interposition is not associated with visceral adhesions in the majority of patients. Polypropylene mesh can be used safely when adequate omental coverage is available.     

Intraperitoneal underlay ventral hernia repair utilizing bilayer expanded polytetrafluoroethylene and polypropylene mesh

A prospective study of patients with ventral hernias was undertaken to study the experience with an open intraperitoneal underlay technique utilizing a bilayer prosthetic mesh. From September 1998 to March 2001, 102 patients underwent repair with a bilayer expanded polytetrafluoroethylene (ePTFE) and polypropylene mesh placed intraperitoneally and fixed in place with full-thickness abdominal muscle wall sutures to achieve a 5-cm underlay of the fascial defect circumferentially. There were 67 females and 35 males ranging in age from 29 to 76 years (mean 53 years). Average patient weight was 207 lb with 64 patients in the obese category. Forty patients presented with recurrent hernias. Mean operative time was 103 minutes with an average diameter hernia defect size of 15 cm. Median hospital stay was 3 days. There was no surgical mortality, and major morbidity occurred in six patients (2 wound infections, one deep vein thrombosis, one myocardial infarction, one pneumonia, and one pulmonary embolus). Mean follow-up is 28 months (range 12-42 months). No recurrence has been found with 100 per cent follow-up to date. No bowel obstruction or enteric fistulas have occurred during the follow-up period. The open intraperitoneal underlay mesh technique can be performed with a zero per cent early recurrence rate. Bilayer prosthetic mesh composed of ePTFE and polypropylene can be safely placed intraperitoneally without causing intestinal obstruction or enteric fistula.     

Primary incisional hernia repair with or without polypropylene mesh: a report on 384 patients with 5-year follow-up

Background and aim Several studies have claimed that mesh repair of incisional hernia lowers recurrence rates when compared to suture repair. We investigated the relative effectiveness of mesh and suture repair in a large homogeneous cohort of patients with primary incisional hernia.Patients and methods In a retrospective single-centre cohort study, a total of 446 consecutive patients were identified, of whom 86% could be followed up. Mean length of follow-up was 5 years. In 79 patients (22%), we implanted a mesh, usually polypropylene (Prolene).Results Compared to suture repair, mesh repair prolonged operating time by over 30 min and caused seroma in 12.7% of the patients (p<0.001). Only 4 of the 79 patients with mesh repair developed recurrence, compared to 55 of the 305 patients with suture repair (5 vs 18%, p=0.02 by log-rank test). In multivariate Cox regression, recurrence rates were fourfold higher after suture than after mesh repair (p=0.02). Interestingly, old age was associated with a decreased susceptibility for recurrence (p=0.01).Conclusion Our data confirms the long-term effectiveness of mesh repair under routine conditions. Suture repair should be restricted to small hernias in patients free of known risk factors.     

Laparoscopic ventral hernia repair using a composite mesh with polypropylene and expanded polytetrafluoroethylene: a prospective,multicentre registry

Background: Abdominal wall hernias are a common problem. Composite meshes placed intraperitoneally for abdominal wall hernia repair are widely used. This registry evaluated the safety and efficacy of one specific composite mesh with polypropylene and expanded polytetrafluoroethylene (Intramesh^® T1) in laparoscopic ventral hernia repair.

Methods: A prospective multicentre registry with data from seven centres was collected between January 2013 and September 2014. Primary endpoint was recurrence rate at 12 months determined by clinical examination. Secondary outcome measures included intraoperative complications, complications during hospitalisation and at 1-month and 12-months follow-up.

Results: The registry included 90 patients (30 female and 60 male). Fifty-five patients (61.1%) presented with primary ventral hernias and 35 patients (38.9%) with incisional ventral hernias. Median hernia size was 4?cm². Intraoperative complications were reported in two patients (2.2%). Complications during hospitalisation were reported in four (4.4%) patients. At 1-month follow-up, 17 (18.9%) patients had postoperative complications, of which 5 complications were major and 19 were minor. Late complications at 12-months were observed in 10 patients (11.1%), of which 2 were major and 8 minor complications.

Conclusion: Intramesh^® T1 is a safe and effective composite mesh with favourable short and midterm outcome and morbidity. (NCT01816867)     

Polypropylene mesh repair of incarcerated and strangulated hernias: a prospective clinical study

Purpose

There is a common doubt regarding the application of polypropylene mesh to treat incarcerated and strangulated hernias due to the possibility of surgical site infection. We aimed to investigate the results of mesh repair of incarcerated and strangulated hernias, and to evaluate the incidence of wound infection and recurrence.

Methods

One hundred and fifty-three consecutive patients with incarcerated and strangulated hernias underwent surgery with mesh repair. The patients were divided into two groups: a resection group and a nonresection group. Fisher’s exact test, the Chi-square test and independent samples t test were used to determine the statistical significance level (p < 0.05).

Results

While 53 patients required organ resection, the remaining 100 patients did not. The most frequently incarcerated organs were the omentum (86), small bowel (74) and colon (15). Most of the resections were performed in the omentum (36), small bowel (23) and colon (2). While five of the 53 patients (9.4 %) in the resection group developed wound infections, no infections were observed in the nonresection group (p = 0.004). The infection rate in all patients was 3.3 % (five of 153 patients). None of the infected patients required mesh removal. There were no mortalities or recurrence in either group.

Conclusions

The findings revealed effective and safe usage of mesh along with antibiotic therapy in patients undergoing incarcerated and strangulated hernia repair.     

Laparoscopic ventral hernia repair

Introduction: Effective surgical therapy for ventral and incisional hernias is problematic. Recurrence rates following primary repair range as high as 25–49%, and breakdown following conventional treatment of recurrent hernias can exceed 50%. As an alternative, laparoscopic techniques offer the potential benefits of decreased pain and a shorter hospital stay. This study evaluates the efficacy of the laparoscopic approach for ventral herniorrhaphy. Methods: A retrospective review was performed for 100 consecutive patients with ventral hernias who underwent laparoscopic repair at our institutions between November 1995 and May 1998. All patients who presented during this period and were candidates for a mesh hernia repair were treated via an endoscopic approach. Results: One hundred patients underwent a laparoscopic ventral hernia repair. There were 48 men and 52 women. The patients were typically obese, with a mean body mass index (BMI) of 31 kg/m². Each had undergone an average of 2.5 (range; 0–8) previous laparotomies. Forty-nine repairs were performed for recurrent hernias. An average of two patients (range; 1–7) had previously failed open herniorhaphies; in 20 cases, intraabdominal polypropylene mesh was present. There were no conversions to open operation. The mean size of the defects was large at 87 cm² (range; 1–480). In all cases, the mesh (average, 287 cm²) was secured with transabdominal sutures and metal tacks or staples. Operative time and estimated blood loss averaged 88 min (range; 18–270) and 30 cc (range; 10–150). Length of stay averaged 1.6 days (range; 0–4). There were 12 minor and (two) major complications: cellulitis of the trocar site (two), seroma lasting >4 weeks (three), postoperative ileus (two), suture site pain > 2 weeks (two), urinary retention (one), respiratory distress (one), serosal bowel injury (one), and skin breakdown (one) and bowel injury (one). Both of the latter complications required mesh removal. With an average follow-up of 22.5 months (range; 7–37), there have been (three) recurrences. Conclusion: The laparoscopic approach to the repair of both primary and recurrent ventral henias offers a low conversion rate, a short hospital stay, and few complications. At 23 months of follow-up, the recurrence rate has been 3%. Laparoscopic repair should be considered a viable option for any ventral hernia.

Laparoscopic ventral hernia repair: a new method for fixation of the mesh with sutures

BACKGROUND: Laparoscopic technique has proven to be a safe and feasible alternative to open mesh repair in the treatment of ventral hernias. It has been seen that the recurrence rate is the same as with open repair but with lesser morbidity. For the repair of ventral hernia with laparoscopy, mesh is placed intraperitoneally. The most common approach for intraperitoneal fixation of the mesh is by using a combination of transfascial sutures and tackers. This paper describes a new technique for intraperitoneal fixation of the mesh using sutures. SURGICAL TECHNIQUE: Adhesions to the previous scar are taken down. Mesh is anchored to the abdominal wall using 4 transfascial sutures at the 4 corners of the mesh. Fixation of the mesh between the transfascial sutures is performed by a new technique using continuous sutures. Fixation of the mesh with tacks is not required. CONCLUSIONS: This is a novel technique for fixation of the mesh to the abdominal wall intraperitoneally during laparoscopic repair of ventral hernia. Tackers are not required for the fixation of mesh.
