Trocar site hernia after laparoscopic ventral hernia repair

Onlay Repair Using Self-Gripping Mesh for Lateral Trocar Site Hernia After Laparoscopic Incisional Hernia Repair: A Case Report With Short- and Mid-Term Outcomes

Introduction

Trocar site hernia (TSH) is an uncommon complication after laparoscopic surgery, but it may potentially require surgical intervention. The available data have shown the importance of prediction and prevention; the optimal surgical approach for TSH remains unclear, and its long-term outcome is scarcely available. Here, we present a case of a lateral TSH after laparoscopic incisional hernia repair, which was successfully repaired using the onlay technique with a self-gripping mesh.

Case presentation

A 74-year-old woman presented with an abdominal incisional hernia at the midline after an open cholecystectomy. She underwent laparoscopic surgery for incisional hernia with intraperitoneal onlay mesh repair. Fascial closure was performed for trocar sites. After 12 months, she noticed a painful bulge in the left upper quadrant suggestive of TSH. At the time of diagnosis, her body mass index was 32 kg/m2. TSH repair was performed under general anesthesia. A 3 × 3 cm defect was identified, and the hernial content was found to be the omentum. Defect closure was performed using interrupted sutures followed by placement of a self-gripping mesh (11 × 11 cm in size, obtaining a 4-cm overlap for the defect). The operative time was 80 minutes. The postoperative course was uneventful except for a spontaneously resolved seroma. Computed tomography scan at the 1-year follow-up and physical examination at the 2-year visit showed no recurrence.

Conclusion

Our proposed onlay repair using self-gripping mesh may be considered as the treatment of choice for cases of lateral TSH after laparoscopic incisional hernia repair.

Laparoscopic Port-Site Hernia: An Underrecognized Iatrogenic Complication of Laparoscopic Surgery

Importance

Port-site hernia is an iatrogenic complication with a documented incidence between 0.65% and 2.8%. However, the true incidence could be higher because of delayed onset, asymptomatic nature, and loss to follow-up. Port-site hernia could be further complicated by incarceration or strangulation leading to small bowel obstruction requiring emergent surgical intervention, thus imposing significant financial and emotional burden to patients.

Objective

This article aims to provide a summary of the available literature concerning port-site hernia and explore preventive strategies for future clinical practice.

Evidence Acquisition

This review was formulated through electronic literature searches in Ovid MEDLINE, Embase, and Cochrane Central Register of Controlled Trials. The reference lists of the included studies were hand searched to identify other relevant articles to capture all available literature in this narrative review.

Results

Following screening for eligibility based on relevance to the topic under consideration, 28 studies were identified. This included 5 original articles, 1 case series, and 22 review articles, including 4 systematic reviews. Included studies were critically appraised in formulating this review.

Conclusions

Port-site hernia is an underrecognized yet preventable complication with careful consideration of predisposing technical and host factors, thorough attention to surgical technique, or use of a fascial closure device.

Relevance

With the widespread and increasing use of laparoscopic methods to treat surgical pathologies, knowledge of this complication is imperative to encourage prevention strategies and facilitate early recognition and management should it occur.

The "Flip-Flap" Technique for Laparoscopic Port-Site Closure-Description of a Novel, Cost-Effective Technique with Review of Literature

Overview  Laparoscopic approach has changed the face of surgical care offered to patients. Almost all surgical procedures across specialties are now undertaken by the laparoscopic approach. Closure of port sites to prevent trocar-site hernias (TSHs) forms an integral part of the laparoscopic procedure. TSH is an area of preventable surgical morbidity. We hereby report our technique that is easily applicable, simple, safe, and highly cost-effective. It requires no additional instruments or retractors, is easy to learn, and has a very favorable safety profile.

Materials and Methods  This prospective case series enrolled a total of 454 port-site closures in 255 patients undergoing different laparoscopic procedures over a period of 2 years. The intraperitoneal tissue forceps were used in the reverse direction to lift the fascia up and a right-angled retractor was used to retract back the skin and subcutaneous tissue. The port-site closure is done under vision and no adverse events were reported.

Results  This technique was used in 454 port sites in 255 patients. No intraoperative incidents were noted. There is no requirement of any specialized instruments or retractors. No additional tissue trauma or dissection is required. There is no extension of operative time. The technique is simple to learn and easy to teach. No bowel injuries or TSHs were reported during a follow-up of 26 months.

Conclusion  The described technique is easy, simple, cost-effective, and has a good safety profile.

Laparoscopic repair of lateral sided trocar site hernias

Objectives

Repair of trocar site hernia (TSH) has been mentioned in a limited number of studies. Trocar site hernias are mostly located in the umbilical region with a small size. Laparoscopic repair could be a choice due to the appearance of large defects and requirement of mesh repair for lateral sided TSH. We aimed to share our experience with laparoscopic repair of lateral sided trocar site hernia (LRTSH) with a long term follow up.

Material and Methods

Twenty-three patients who underwent LRTSH between March 2013 and July 2015 were included in our study. Four edges of the mesh were fixed with pre-tied 2/0 polypropylene suture for 9 patients initially (Group 1). Unexpected complication of chronic pain in 3 patients led us to revise our method and we avoided to position the mesh with transabdominal sutures for the rest of the patients (Group 2).

Results

Nineteen (82.6%) female and 4 (17.4%) male patients, with a mean age of 50.9 years underwent laparoscopic repair. Following the revision and avoiding transabdominal sutures to position the mesh, no complaint of chronic pain was observed, and the difference was statistically significant between the groups (p<0.05).

Conclusion

Previous laparoscopic surgery indicates the lack of obstacle in laparoscopic repair of TSH, and LRTSH can be considered as first option in treatment. Shorter mean operative time in obese patients and lack of recurrence in our series support this view. Using transabdominal sutures should be avoided to prevent chronic pain in LRTSH.

Efficacy and reliability of the use of a needle grasper to prevent trocar site hernia

Introduction

Port site herniation is one of the serious complications of laparoscopic surgery, which decreases its benefits. Closure of a fascia defect at the port site is an important problem of laparoscopic surgery, especially in obese patients.

Aim

To evaluate needle grasper fascia closure.

Material and methods

We closed the port site fascia using a percutaneous organ-holding device (needle grasper) in laparoscopic cholecystectomy patients. This study included 334 patients who underwent laparoscopic cholecystectomy between January 2015 and January 2017 in our hospital. Patients were divided into 2 fascia closure groups: group 1 with a standard simple suturing technique and group 2 with a needle grasper to close the port site. Patient demographics, operative details, and postoperative outcomes were collected and evaluated.

Results

There were 243 female and 91 male (total 334) patients with the mean age of 49.18 ±13.15 years. Only 1 patient in the BMI > 30 kg/m² group of patients had port site hernia development with the needle grasper technique at the end of the 8-month follow-up period. The port site hernia incidence was higher in group 1 than group 2 (p < 0.001), but there was no significant difference in terms of operation duration between the two groups (p < 0.001, p = 0.709, respectively). In patients with a BMI > 30 kg/m², both operation duration and port site hernia incidence were higher in simple suture closure than in the needle grasper technique (p < 0.001, p = 0.016, p = 0.005).

Conclusions

The needle grasper technique is easy, simple, safe, fast, and effective for fascia closure of port sites. This method can also be applied in obese patients easily, safely and in a short time.

Case report of an uncommon case of drain-site hernia after colorectal surgery

•

Trocar site herniation is a rare but potentially serious complication of laparoscopic surgery.

•

We report an uncommon case of drain site hernia.

•

The risk of trocar site hernia in laparoscopy has been known since 1967.

•

Other two cases are described in literature regarding pediatric and gynaecologic patients.

•

Drain should not be positioned through the 10 mm trocar in order to avoid any herniation.

Background

trocar site herniation is a rare but potentially serious complication of laparoscopic surgery. Data about drain site hernia after laparoscopic surgery is scarce and anecdotal.

Case presentation

we report an uncommon case of drain site hernia in a man undergone laparoscopic left colectomy for a colonic adenocarcinoma who developed small bowel herniation in a 10 mm port site, in which a 24 FR drain was inserted leaving a real free space of 2 mm.

Discussion

laparoscopic approach has gained widespread acceptance in each surgical fields because of the perceived better postoperative outcomes in terms of less pain, faster recovery, and lower risk of incisional hernia. However, the risk of trocar site hernia has been known since 1967. Different risk factors for the development of trocar site hernia are described in literature: the trocar diameter and design, preexisting fascial defects, enlargement of a port site to remove a specimen, high blood glucose levels, obesity, increase intra-abdominal pressure as in chronic obstructive airway disease or extensive manipulation of the trocar during surgical intervention, which may enlarge the trocar site and thus induce small bowel herniation.

However, the most important recognized risk factor for trocar site hernia is the size of the trocar.

Conclusions

waiting for further studies, the lesson to be learnt from this case report is that, even if the free space after drain positioning is minimal, drain should not be positioned through the 10 mm trocar to allow the closure of fascial defect in order to avoid any herniation.

The suture pullout characteristics of human and porcine linea alba

There is a substantial prevalence of post-operative incisional hernia for both laparoscopic and laparotomy procedures, but there have been few attempts at quantifying abdominal wound closure methodology in the literature. One method to ascertain a more robust method of wound closure is the identification of the influence of suture placement parameters on suture pullout force. Current surgical practice involves a recommended bite depth and bite separation of 10mm, but the evidence base for this is not clear. In this paper, the suture pullout characteristics of both porcine and human linea alba were investigated to ascertain a suture placement protocol for surgical wound closure. Uniaxial suture pullout force testing on fresh frozen porcine and human linea alba samples was performed using standard materials testing machines. The influence of the number of suture loops, the bite depth and the bite separation of the sutures and the orientation of the sutures with respect to the principal fibre direction in the linea alba were assessed. Results showed a clearly identifiable relationship between pullout force of the suture, bite separation and bite depth, with low suture separation and high suture depth as optimal parameters for increasing pullout force. Resistance to pullout could be improved by as much as 290% when optimizing test conditions. Both human and porcine tissue were observed to exhibit very similar pullout force characteristics, corroborating the use of a porcine model for investigations into wound closure methodology. Orientation of suture application was also found to significantly affect the magnitude of suture pullout, with suturing applied longitudinally across a transverse defect resulting in higher pullout forces for small suture bite separations. Although further assessment in an environment more representative of in vivo conditions is required, these findings indicate that increasing the bite depth and reducing the bite separation with respect to the current surgical recommendations may reduce the risk of post-operative incisional hernia.

Percutaneous trans-abdominal external looped needle with two holes in the trocar sheath for port-site closures in difficult obese cases

INTRODUCTION

Port closure is essential after successful laparoscopic surgery to prevent incisional hernia. However, good fascial closure still represents a problem, especially in obese patients and when the port wound is oblique. We report a novel technique for port-site closures in such cases.

METHODS

This study involved 67 obese patients who underwent laparoscopic surgery. We used a novel technique for port-site closure that employed a looped needle passed through two holes in the port sheath.

RESULTS

The method was used in 67 patients (45 laparoscopic cholecystectomies, 22 laparoscopic hernia repairs), with a mean BMI of 35.7 kg/m² . No intraoperative incidents or port-site hernias were reported during follow-up (mean, 22 months).

CONCLUSION

Our procedure is safe, easy, and effective for fascial port site closures, especially in cases of difficult obese patients and oblique port wounds.

Effective, simple, easy procedure for laparoscopic port closure in difficult cases

Background

Laparoscopic and rebotic surgery is widely practiced in modern medicine. The operative procedure is not complete until the port sites are closed with a fascial closure. Good fascial closure still represents problem, especially in difficult obese patients. This study reported simple technique is suitable in such cases.

Material and methods

We herein describe a simple technique for fascial closure after Laparoscopic surgery using percutaneous transabdominal approach by using two looped needles in 87 obese patients. This technique was done while the trocar sheath in its position.

Results

The procedure was used in 87 patients (69 females and 18 males) after laparoscopic cholecystectomy with mean body mass index 35.5 kg/m2 and mean age 47.1 years from May 2013 through June 2015. No intra-operative incidents and no port sites hernias were reported during a mean follow up of 18 months.

Conclusion

The procedure is easy to perform, safe, and effective for fascial port site closure in difficult obese (thick abdominal wall and oblique port wound) cases.

•

The complete fascial closure of port site is essential for good outcome of laparoscopic surgery.

•

Port site herniation is serious complication leading to loss all mini-invasive surgery advantages.

•

Our technique is done under direct visualization and trocar sheath in its position.

•

Our procedure is effective, easy to produce complete fascial closure at any port site type and in any case.

Hybrid transvaginal incisional hernia repair

AIM

Natural orifice translumenal endoscopic surgery (NOTES(®); American Society for Gastrointestinal Endoscopy [Oak Brook, IL] and Society of American Gastrointestinal and Endoscopic Surgeons [Los Angeles, CA]) is a new approach that allows surgical manipulations and specimen extractions through the natural orifices such as the vagina. There have been limited numbers of cases about the adaptation of NOTES for ventral hernia repairs. Here, we aimed to present two more cases and highlight our technical differences compared with the previously reported instances.

PATIENTS AND METHODS

Two patients (43 and 46 years old; body mass index of 29 and 30 kg/m(2), respectively) were treated with hybrid transvaginal incisional hernia repairs. Two 5-mm abdominal trocars were used to monitor transvaginal access, adhesiolysis, dissection of the hernia, and tuckering of the mesh. A 15-mm transvaginal trocar was used for scope and mesh introduction into the abdomen. Defects were 3-5 cm in diameter.

RESULTS

A rigid 5-mm laparoscope was used. The composite synthetic meshes were, respectively, 11 and 13 cm in diameter. These were passed through the vagina without any protection such as a bag or sheath. No conversion or additional port was required. Respective operative times were 120 and 180 minutes, and the patients were discharged uneventfully on the second day. One patient had seroma, which was managed conservatively (aspiration of 20 mL on Day 7). There were no recurrences after 7 and 13 months, respectively.

CONCLUSIONS

Conventional laparoscopic equipment can be used for hybrid transvaginal incisional hernia repair. An anti-adhesive synthetic mesh can be inserted through the vaginal trocar without protective devices. The main advantage of this technique is to avoid 10-15-mm abdominal trocars, which increase the risk of trocar-site hernias themselves.

Wound complications in 1145 consecutive transumbilical single-incision laparoscopic procedures

OBJECTIVE

To evaluate the wound complication rate in patients undergoing transumbilical single-incision laparoscopic (SIL) surgery.

BACKGROUND

SIL surgery claims to be less invasive than conventional laparoscopy. Small SIL series have raised concerns toward a higher wound complication rate related to the transumbilical incision.

METHODS

In a 44-month period, 1145 consecutive SIL procedures were included. The outcomes were assessed according to the intention-to-treat analysis principle. All procedures were followed for a minimum of 6 months postoperatively, and wound complications were recorded as bleeding, infection (superficial/deep), or hernia. Patients were classified as having a wound complication or not. For all comparisons, significance level was set at P<0.05.

RESULTS

Pure transumbilical SIL surgery was completed in 92.84%, and additional trocars were used in 7.16%. After a median follow-up of 22.1 (range, 7.67-41.11) months, 29 wound complications (2.53%) had occurred [bleeding 0%/infection 1.05% (superficial 0.9%/deep 0.17%)/early-onset hernia 0.09%/late-onset hernia 1.40%, respectively]. Factors associated with complications were higher patient body mass index (28.16±4.73 vs 26.40±4.68 kg/m; P=0.029), longer skin incisions (3.77±1.62 vs 2.96±1.06 cm; P=0.012), and multiport SIL versus single-port SIL (8.47% vs 2.38%; P=0.019) in complicated versus uncomplicated procedures. Furthermore, a learning curve effect was noted after 500 procedures (P=0.015).

CONCLUSIONS

With transumbilical SIL surgery, the incidence of wound complications is acceptable low and is further reduced once the learning curve has been passed.

Case Series of Umbilical and Extra-umbilical Port Site Herniae

Trocar site hernia or port site hernia (PSH) is a type of incisional hernia occurring at the trocar sites after laparoscopic surgeries. This is a rare but a potentially dangerous complication, as it can lead to considerable morbidity requiring surgical intervention. Various factors have been implicated for its development and various methods are also suggested for its prevention. We present here five cases of port site herniae.

Incidence and risk factors for trocar site hernia following laparoscopic cholecystectomy: a long-term follow-up study

BACKGROUND

The aim of this retrospective study was to assess the incidence of trocar site hernias (TSH) following laparoscopic cholecystectomy (LC) through a long-term follow-up and to elucidate the significance of several technical and patient-related factors.

METHODS

A total of 313 patients submitted to LC between 2000 and 2004 were included in our study. The pneumoperitoneum was always performed by means of Hasson's technique at the umbilical site and the operative trocars were positioned using either the American technique or the French technique. Closure of the fascial defect was performed only at the umbilical site. The effects of several variables, including age, gender, size of gallstones, co-existing umbilical hernia, complexity of operation, diabetes, obesity, malnutrition, smoking, and heavy manual work on the development of TSH were assessed by univariate and multivariate models.

RESULTS

Thirteen cases of TSH (4.1 %) were detected over a mean follow-up period of 89.8 months (range: 60-128). Of these, 11 (84.6 %) developed at the umbilicus and 2 at the 10 mm subxiphoid site (15.4 %). At univariate and multivariate analysis, gallstones ≥ 2 cm (p = 0.030; OR = 9.95, p = 0.01) and obesity (p = 0.002; OR = 22.93, p < 0.01) were found to increase the likelihood of TSH development.

CONCLUSIONS

After long-term follow-up, the incidence of TSH following LC was higher than expected. The insertion of large trocars at the umbilical site plays a key role in the development of TSH. Other conditions such as obesity and large gallstones can be additional risk factors since the umbilical defect must often be widened in these cases.

Multicentre prospective feasibility study on the repair of hernias and incisional ventral hernias with an innovative Tintrap mesh

BACKGROUND

The aim of this study is to assess an innovative prosthesis Tintrap Mesh and its inserter in the repair of hernias and incisional ventral hernias. The inserter helps the deployment of the mesh the same way an umbrella would open, which prevents the enlargement of the wound.

METHOD

Four centres took part in this study. A questionnaire was completed preoperatively, postoperatively and after 1 month of surgery. Data on pain and complications, patients' satisfaction, as well as the ease of installation and the quality of deployment of the mesh was gathered and assessed.

RESULTS

From January 2009 to December 2009, 80 patients were assessed. The prosthesis, ease of installation and the deployment quality were rated "very good" and "good". The average operating room time was 20.86 min (range: 10-50 min). Postoperative pain was rated level 0 and 3 on VAS score in 73 cases (91.25%). After 1 month, no occlusion or relapse were reported on 77 patients; 82.47% of patients had no pain. One seroma required the removal of the mesh.

CONCLUSION

The first set of results on 80 cases is encouraging judging by the simplicity of implantation, low postoperative pain and patient's satisfaction.

Port-site hernia following laparoscopic cholecystectomy

The incidence of port-site hernia is variable, but evidence suggests that awareness of risk factors and modification of technique can minimize risk.

Background:

Port-site hernia is a rare but potentially serious complication of laparoscopic cholecystectomy. This study aimed to review the current literature, assess the incidence and causes of port-site hernias, and identify methods to reduce the risk.

Methods:

A systematic search of the literature published in English from 1995 to 2010 was conducted using PubMed to identify all reports of port-site, trocar-site, or incisional hernia following laparoscopic cholecystectomy. Studies in over 100 patients were identified before the application of defined exclusion criteria. The incidence of port-site hernia was calculated and compared with historical data. Predisposing factors were reviewed.

Results:

Seven studies met the search criteria, with 99 port-site hernias in 5984 patients. The overall incidence of port-site hernia was 1.7% (range, 0.3% to 5.4). The most important factors were older age, higher body mass index, preexisting hernia, trocar design, trocar diameter, increased duration of surgery, and extension of the port site for gallbladder extraction.

Conclusion:

The incidence of port-site hernia is low but likely to be underestimated and has not declined over time. Awareness of the predisposing factors and modification of techniques may help to reduce the risk.

Low risk of trocar site hernia repair 12 years after primary laparoscopic surgery

BACKGROUND

The risk of trocar site hernia (TSH) may be 0-22%, but no large scaled data with long-term follow-up are available. The purpose of this study was to estimate the long-term risk of TSH repair.

METHODS

All patients in Denmark who underwent a laparoscopic procedure in 1997 were identified using the Danish National Patient Register and followed during a 12-year period. Hospital records for patients with an incisional or umbilical hernia repair were tracked and manually analyzed for possible relationship between reoperation and the initial laparoscopy.

RESULTS

We included 7,626 patients. During follow-up, we identified 95 patients with TSH repair with a cumulative risk of 1.3% being lowest after minor gynecological procedures and appendectomy and highest after fundoplication, cholecystectomy, and oophorectomy. The TSH was mainly at the umbilicus site (n = 63, 66%), and 15 (16%) of the TSH repairs were performed as an emergency procedure.

CONCLUSIONS

The long-term risk of TSH repair is low, but the risk of an emergency operation for TSH is relatively high, which suggests that all patients with a TSH should be offered elective repair.

Trocar site hernia after laparoscopic colectomy: a case report and literature review

Background. Trocar Site Hernia (TSH) is defined as an incisional hernia which occurs after minimally invasive surgery on the trocar incision site.In 2004 Tonouchi classified trocar site hernias into 3 types: Early onset type; Late onset type; Special type. Case Report. We report the case of a 76-year old woman that underwent an emergency explorative laparotomy on the 10th p.o. day after a laparoscopic left hemicolectomy. Surgery showed a small bowel herniation through the 12 mm trocar incision site; the intestinal loop appeared necrotic and had to be resected, and the hernia orifice was repaired. We carried out a review of literature about this topic. Discussion. The clinical onset of a trocar site hernia is usually early, occurring within the 30th post operative day and it is caused by the omentum or small bowel entrapment into the trocar orifice. The clinical presentation is insidious, with progression to an acute abdomen, and an emergency surgical approach is often required. Conclusions. TSH is a severe complication of operative laparoscopy especially with large-bore trocar ports. The incidence of TSH resulting from our review ranges from 0.007% to 22% with an average of 1.85%. Prevention of TSH appears to be more effective when trocar insertion through the abdominal wall is tangential, the closure of both the fascia and the peritoneum is performed if the incision is greater than 7 mm, the suture of extra umbilical port site is performed under laparoscopic vision.

[Trocar site incisional hernia in laparoscopic surgery]

Trocar site incisional hernias (TSIH) are the most common complications in laparoscopic surgery. We have carried out a review of the literature with the aim of establishing their incidence, the reasons for them happening, and their prevention. After a search in the MEDLINE PubMed and PubMed CENTRAL data bases from 1991 to 2009, combining the words: "hernia", "laparoscopy" and "trocar", we obtained 545 articles, of which we analysed 60 of them. The incidence of TSIH varies between 0.18% and 2.8%. The diameter of the trocar, obesity and age play a fundamental role when proceeding to close the fascia, a closure which is the most important factor to prevent these incisional hernias appearing. The appearance of new laparoscopic material and the increasing more common closure of defects of the fascia means that new and more extensive prospective studies should be performed.

Trocar site hernia after laparoscopic surgery: a qualitative systematic review

PURPOSE

There is a risk of developing a trocar site hernia (TSH) after laparoscopic surgery, but data is sparse and based mostly on retrospective studies with a short and poorly defined follow-up period. Surgical approaches and patient-related co-morbidity have also been suggested as risk factors for development of TSH. The aim of the present review was to perform a qualitative systematic analysis to estimate the incidence of TSH and to discuss the surgical and patient-related risk factors for development of TSH.

METHODS

The literature search was until 19 May 2010. Studies with TSH, defined as either operation for TSH or a hernia found during clinical follow-up, were included. We included randomised controlled trials, prospective non-controlled studies including >200 patients, and retrospective studies including >200 patients. The review was completed according to the PRISMA guidelines.

RESULTS

We included 19 studies in adults and 3 studies in paediatric patients (<18 years), and a total of 30,568 adults and 1,098 children were analysed. The overall incidence of TSH was 0-5.2%. TSH occurred most often (96%) in trocar sites of a minimum of 10 mm, located mostly in the umbilicus region (82%). Data supported a higher incidence of TSH when the trocar site fascia was not sutured, and in pre-school children undergoing a laparoscopic procedure.

CONCLUSIONS

Current data suggests a relatively low incidence of TSH but that all trocar incisions of a minimum of 10 mm should be closed. In pre-school children undergoing laparoscopic surgery, all port sites should be closed.

Single-port access prosthetic repair for primary and incisional ventral hernia: toward less parietal trauma

BACKGROUND

Although still under development, single-port access (SPA) approach may be of interest in patients prone to port-side incisional hernia, ensuring absence of increased fascial incision. This forms the basis for evaluating SPA for prosthetic ventral hernia repair. We report a new SPA technique of ventral hernia repair using working-channel endoscope, standard laparoscopic instruments, and 10-mm port.

METHODS

Prospective experience with SPA prosthetic repair of primary and incisional ventral hernia in 52 patients for 55 ventral hernias is presented. Median (range) patient age was 46 years (26-85 years), and BMI was 28 kg/m2 (20-38 kg/m2). Mean fascial defect was 16.2 cm2 for primary hernia (n=23) and 48.3 cm2 for incisional hernia (n=32). Intraperitoneal composite mesh repair was achieved through single 10-mm flank port using working-channel endoscope. Meshes were fixed using absorbable tackers and transfascial stitches.

RESULTS

SPA repair of primary and incisional ventral hernia was completed in all cases without conversion to standard laparoscopy. Median (range) operative time was 54 min (39-95 min). Mesh size ranged from 118 to 500 cm2. No intra- or postoperative complications were recorded, except two seromas. Median (range) hospital stay was 1 day (1-5 days). One patient presented prolonged postoperative pain on mesh fixation that resolved after 3 months. No recurrence or port-site incisional hernias have been recorded at median (range) follow-up of 16 months (3-28 months).

CONCLUSIONS

SPA prosthetic repair of primary and incisional ventral hernia is easily feasible according to natural exposition by pneumoperitoneum and gravity. In the present series, SPA ventral hernia repair appears to be safe for experienced SPA surgeons. It may decrease parietal trauma and scarring in patients prone to incisional hernia. SPA repair may be associated with a decrease in rate of port-site incisional hernia compared with multiport laparoscopy, but this has to be verified by randomized trial with standard laparoscopic approach on long-term follow-up.

Laparoscopic ventral hernia repair: innovative anatomical closure, mesh insertion without 10-mm transmyofascial port, and atraumatic mesh fixation: a preliminary experience of a new technique

BACKGROUND

Generous overlap by a well-transfixed mesh is important in laparoscopic ventral hernia repair (LVHR). Mesh is usually introduced through a 10-mm trocar and fixed by tackers or transfixed by sutures. Ten-millimeter trocar sites are more prone to hernia development. Transfixation done using a suture passer inflicts some trauma and the site may become painful. This study reports a mesh insertion technique avoiding a 10-mm myofascial port, double-breasted fascial closure of the hernial defect, and transfixation in a relatively atraumatic manner.

METHODS

This prospective study was conducted by enrolling the patients attending our surgery clinic. They were candidates for LVHR. Informed consent was obtained from each patient before the procedure. The study was approved by the Ethical Review Board of the Hospital and conducted as per good clinical practice (GCP) guidelines.

RESULTS

Between April 2004 and June 2006, 29 ventral hernia patients were enrolled without any exclusion. All patients had LVHR performed with this technique. Mean operative time and hospital stay were 65 min and <1 day, respectively. There were no perioperative complications, conversion, infection, trocar site or recurrent herniation or mortality. The majority of the patients were operated on as day-care surgery. Patients were followed up telephonically for the first 48 h and then by visiting us regularly. There was no postoperative visible bulge.

CONCLUSION

Mesh insertion by avoiding 10-mm trocar, double-breasted defect closure, and transfixation using atraumatic needles is a technically easy, safe, and patient-friendly procedure.

Prevention of Trocar Site Hernias: Description of the Safe Port Plug Technique and Preliminary Results

The aim of this study was to describe a new technique to prevent the development of incisional hernias in trocar sites. Between March and June 2006, a pilot study was conducted to determine the feasibility of the safe port plug technique using the Bioabsorbable Hernia Plug to prevent incisional hernia in trocar sites. The device was implanted in the umbilical trocar site (10-11 mm) of 17 patients undergoing laparoscopic surgery during the study period. The mean follow-up of patients was 14.6 months. Implantation of the Bioabsorbable Hernia Plug device by the safe port plug technique was possible in all cases. No patient presented complications in the follow-up. Our preliminary experience suggests that this technique is simple and feasible, and we hypothesized that this technique could be superior to conventional fascial closure: a hypothesis that must be proven in a randomized prospective trial that is currently in progress.

Trocar-site hernia as a typical postoperative complication of minimally invasive surgery among preschool children

BACKGROUND

Minimally invasive surgery (MIS) in preschool children (<5 years of age) is not common yet, and few reports evaluating typical complications are available. Trocar site hernias are well described in adult patients but also have been reported for preschool children. The goal of our study was to determine incidence and relevance of trocar site hernias as complications of minimally invasive surgery in preschool children.

METHODS

Retrospective analysis of all pediatric patients who underwent minimally invasive surgery at a single institution. Review of the literature.

RESULTS

Trocar site hernias are significantly more frequent in preschool children than in older ones (p = 0.006). Complication rates at all are not significantly different. Trocar site hernias in infants are mainly of type 3 (omental protrusion) and occur within the first postoperative week.

CONCLUSION

Meticulous suturing of all layers (particularly the peritoneum) even in small incisions (2 mm) is recommended to prevent omental protrusion at trocar site in children up to 5 years of age.
