INTRODUCTION The concept of using a mesh to repair hernias was introduced over 50 years ago. Mesh repair is now standard in most countries and widely accepted as superior to primary suture repair. As a result, there has been a rapid growth in the variety of meshes available and choosing the appropriate one can be difficult. This article outlines the general properties of meshes and factors to be considered when selecting one. MATERIALS AND METHODS We performed a search of the medical literature from 1950 to 1 May 2009, as indexed by Medline, using the PubMed search engine (

Surgical mesh has become an indispensable tool in hernia repair to improve outcomes and reduce costs; however, efforts are constantly being undertaken in mesh development to overcome postoperative complications. Common complications include infection, pain, adhesions, mesh extrusion and hernia recurrence. Reducing the complications of mesh implantation is of utmost importance given that hernias occur in hundreds of thousands of patients per year in the United States. In the present review, the authors present the different types of hernia meshes, discuss the key properties of mesh design, and demonstrate how each design element affects performance and complications. The present article will provide a basis for surgeons to understand which mesh to choose for patient care and why, and will explain the important technological aspects that will continue to evolve over the ensuing years.

Background: Incarcerated inguinal hernia is a commonly encountered urgent surgical condition, and tension-free repair is a well-established method for the treatment of non-complicated cases. However, due to the risk of prosthetic material-related infections, the use of mesh in the repair of strangulated or incarcerated hernia has often been subject to debate. Recent studies have demonstrated that biomaterials represent suitable materials for performing urgent hernia repair. Certain studies recommend mesh repair only for cases where no bowel resection is required; other studies, however, recommend mesh repair for patients requiring bowel resection as well. Aim: The aim of this study was to compare the outcomes of different surgical techniques performed for strangulated hernia, and to evaluate the effect of mesh use on postoperative complications. Study Design: Retrospective cross-sectional study. Methods: This retrospective study was performed with 151 patients who had been admitted to our hospital’s emergency department to undergo surgery for a diagnosis of incarcerated inguinal hernia. The patients were divided into two groups based on the applied surgical technique. Group 1 consisted of 112 patients treated with mesh-based repair techniques, while Group 2 consisted of 39 patients treated with tissue repair techniques. Patients in Group 1 were further divided into two sub-groups: one consisting of patients undergoing bowel resection (Group 3), and the other consisting of patients not undergoing bowel resection (Group 4). Results: In Group 1, it was observed that eight (7.14%) of the patients had wound infections, while two (1.78%) had hematomas, four (3.57%) had seromas, and one (0.89%) had relapse. In Group 2, one (2.56%) of the patients had a wound infection, while three (7.69%) had hematomas, one (2.56%) had seroma, and none had relapses. There were no statistically significant differences between the two groups with respect to wound infection, seroma

The use of mesh to reinforce crural closure during hiatal hernia repair is controversial. Although some studies suggest that using synthetic mesh can reduce recurrence, synthetic mesh can erode into the esophagus and in our opinion should be avoided. Studies with absorbable or biologic mesh have not proven to be of benefit for recurrence. The aim of this study was to evaluate the outcome of hiatal hernia repair with modern resorbable biosynthetic mesh in combination with adjunct tension reduction techniques. We retrospectively analyzed all patients who had crural reinforcement during repair of a sliding or paraesophageal hiatal hernia with Gore BioA resorbable mesh. Objective follow-up was by videoesophagram and/or esophagogastroduodenoscopy. There were 114 patients. The majority of operations (72%) were laparoscopic primary repairs with all patients receiving a fundoplication. The crura were closed primarily in all patients and reinforced with a BioA mesh patch. Excessive tension prompted a crural relaxing incision in four per cent and a Collis gastroplasty in 39 per cent of patients. Perioperative morbidity was minor and unrelated to the mesh. Median objective follow-up was one year, but 18 patients have objective follow-up at two or more years. A recurrent hernia was found in one patient (0.9%) three years after repair. The use of crural relaxing incisions and Collis gastroplasty in combination with crural reinforcement with resorbable biosynthetic mesh is associated with a low early hernia recurrence rate and no mesh-related complications. Long-term follow-up will define the role of these techniques for hiatal hernia repair.

The utility of mesh reinforcement for small hiatal hernia found especially during antireflux surgery is unknown. Initial reports for the use of biological mesh for crural reinforcement during repair for defects greater than 5 cm have been shown to decrease recurrence rates. This study compares patients with small hiatal hernias who underwent onlay biologic mesh buttress repair versus those with suture cruroplasty alone. This is a single-institution retrospective review of all patients undergoing repair of hiatal hernia measuring 1-5 cm between 2002 and 2009. The patients were evaluated based on surgical repair: one group undergoing crural reinforcement with onlay biologic mesh and other group with suture cruroplasty only. Seventy patients with hiatal hernia measuring 1-5 cm were identified. Thirty-eight patients had hernia repair with biologic mesh, and 32 patients had repair with suture cruroplasty only. Recurrence rate at 1 year was 16% (5/32) in patients who had suture cruroplasty only and 0% (0/38) in the group with crural reinforcement with absorbable mesh (statistically significant, P = 0.017). Suture cruroplasty alone appears to be inadequate for hiatal hernias measuring 1-5 cm with significant recurrence rate and failure of antireflux surgery. Crural reinforcement with absorbable mesh may reduce hiatal hernia recurrence rate in small hiatal hernias.

In modern hernia surgery, there are two competing mesh concepts which often lead to controversial discussions, on the one hand the heavyweight small porous model and on the other, the lightweight large porous hypothesis. The present review illustrates the rationale of both mesh concepts and compares experimental data with the first clinical data available. In summary, the lightweight large porous mesh philosophy takes into consideration all of the recent data regarding physiology and mechanics of the abdominal wall and inguinal region. Furthermore, the new mesh concept reveals an optimized foreign body reaction based on reduced amounts of mesh material and, in particular, a significantly decreased surface area in contact with the recipient host tissues by the large porous model. Finally, recent data demonstrate that alterations in the extracellular matrix of hernia patients play a crucial role in the development of hernia recurrence. In particular, long-term recurrences months or years after surgery and implantation of mesh can be explained by the extracellular matrix hypothesis. However, if the altered extracellular matrix proves to be the weak area, the decisive question is whether the amount of material as well as mechanical and tensile strength of the surgical mesh are really of significant importance for the development of recurrent hernia. All experimental evidence and first clinical data indicate the superiority of the lightweight large porous mesh concept with regard to a reduced number of long-term complications and particularly, increased comfort and quality of life after hernia repair.

The use of mesh in laparoscopic paraesophageal hiatal hernia repair (LHR) may reduce the risk of late hernia recurrence. The aim of this study was to evaluate initial outcomes and recurrence rate of 92 patients who underwent LHR reinforced with a synthetic bioabsorbable mesh. Surgical approaches included LHR and Nissen fundoplication (n = 64), LHR without fundoplication (n = 10), reoperative LHR (n = 9), LHR with a bariatric operation (n = 6), and emergent LHR (n = 3). The mean length of hospital stay was 2 ± 3 days (range, 1 to 30 days). There were no conversions to open laparotomy and no intraoperative complications. One of 92 patients (1.1%) required intensive care unit stay. The 90-day mortality was zero. Minor complications occurred in 3.3 per cent, major complications in 2.2 per cent, and late complications in 5.5 per cent of patients. There were no perforations or early hernia recurrence. The 30-day reoperation rate was 1.1 per cent. For patients with available 1-year follow-up, the overall recurrence rate was 18.5 per cent with a mean follow-up of 30 months (range, 12 to 51 months). LHR repair with mesh is associated with low perioperative morbidity and no mortality. The use of bioabsorbable mesh appears to be safe with no early hiatal hernia recurrence or late mesh erosion. Longer follow-up is needed to determine the long-term rate of hernia recurrence associated with LHR with mesh.

Laparoscopic-assisted ventral hernia repair (LAVHR) with mesh is well established as the preferred technique for hernia repair. We sought to determine whether primary fascial closure and/or overlap of the mesh reduced recurrence and/or complications. We conducted a retrospective review on 57 LAVHR patients using polyester composite mesh between August 2010 and July 2013. They were divided into mesh-only (nonclosure) and primary fascial closure with mesh (closure) groups. Patient demographics, prior surgical history, mesh overlap, complications, and recurrence rates were compared. Thirty-nine (68%) of 57 patients were in the closure group and 18 (32%) in the nonclosure group. Mean defect sizes were 15.5 and 22.5 cm(2), respectively. Participants were followed for a mean of 1.3 years [standard deviation (SD) = 0.7]. Recurrence rates were 2/39 (5.1%) in the closure group and 1/18 (5.6%) in the nonclosure group (P = 0.947). There were no major postoperative complications in the nonclosure group. The closure group experienced four (10.3%) complications. This was not a statistically significant difference (P = 0.159). The median mesh-to-hernia ratio for all repairs was 15.2 (surface area) and 3.9 (diameter). Median length of stay was 14.5 hours (1.7-99.3) for patients with nonclosure and 11.9 hours (6.9-90.3 hours) for patients with closure (P = 0.625). In conclusion, this is one of the largest series of LAVHR exclusively using polyester dual-sided mesh. Our recurrence rate was about 5 per cent. Significant mesh overlap is needed to achieve such low recurrence rates. Primary closure of hernias seems less important than adequate mesh overlap in preventing recurrence after LAVHR.

Along with advantages, evolving surgical techniques bring unique complications. A young male developed urinary symptoms a few months after undergoing laparoscopic inguinal hernia repair. On evaluation, mesh erosion into the urinary bladder was found. Removal of mesh with repair of bladder was done. A vesico-cutaneous fistula resulted which was managed with repeat surgery. We review all such cases reported in literature; discuss the etiopathogenesis, presentation, management and possible preventive measures. To the best of our knowledge, this is only the 12th case being reported. PMID:28281479

The use of biomaterial meshes in the repair of incisional abdominal wall hernias is now widely accepted internationally. The introduction of synthetic meshes to achieve tension-free repair has led to a satisfactory reduction in the recurrence rate to less than 10%. However, the use of such biomaterials can result in the occurrence of undesirable complications such as increased risk of infection, seromas, restriction of the abdominal wall and failure caused by mesh shrinkage. Additionally, at the time of writing there is much discussion concerning the potential risk of a persistent foreign body reaction directly associated with the meshes with regard to possible malignant transformation. As such, the trend seems to be toward the use of lighter meshes utilizing less non-absorbable material. One particular novel mesh theoretically capable of guaranteeing the necessary mechanical stability uses 70% less biomaterial. Against this background, we report a central mesh recurrence through the mesh following incisional hernia repair with a Marlex mesh. To our knowledge, this is the first description of a central mesh recurrence, and we discuss a possible mechanism with particular emphasis on the required abdominal wall forces both physiologically and after incisional hernia repair.

Purpose. To evaluate the feasibility, safety, and effectiveness of laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair using a memory-ring patch (Polysoft™ mesh). Patients and Methods. Between April 2010 and March 2013, a total of 76 inguinal hernias underwent TAPP repair using Polysoft mesh in 67 adults under general anesthesia. Three different senior resident surgeons performed TAPP repair under the instruction of a specialist surgeon. Nine patients had bilateral hernias. The 76 hernias included 37 indirect inguinal hernias, 29 direct hernias, 1 femoral hernia, 1 pantaloon hernia (combined direct/indirect inguinal hernia), and 8 recurrent hernias after open anterior hernia repair. The immediate postoperative outcomes as well as the short-term outcomes (mainly recurrence and incidence of chronic pain) were studied. Results. There was no conversion from TAPP repair to anterior open repair. The mean operation time was 109 minutes (range, 40–132) for unilateral hernia repair. Scrotal seroma was diagnosed at the operation site in 5 patients. No patient had operation-related orchitis, testicle edema, trocar site infection, or chronic pain during follow-up. Conclusions. The use of Polysoft mesh for TAPP inguinal hernia repair does not seem to adversely affect the quality of repair. The use of this mesh is therefore feasible and safe and may reduce postoperative pain. PMID:27635414

Background and Objectives: We aimed to evaluate the first human use of magnetic resonance–visible implants for intraperitoneal onlay repair of incisional hernias regarding magnetic resonance presentability. Methods: Ten patients were surgically treated with intraperitoneally positioned superparamagnetic flat meshes. A magnetic resonance investigation with a qualified protocol was performed on postoperative day 1 and at 3 months postoperatively to assess mesh appearance and demarcation. The total magnetic resonance–visible mesh surface area of each implant was calculated and compared with the original physical mesh size to evaluate potential reduction of the functional mesh surfaces. Results: We were able to show a precise mesh demarcation, as well as accurate assessment of the surrounding tissue, in all 10 cases. We documented a significant decrease in the magnetic resonance–visualized total mesh surface area after release of the pneumoperitoneum compared with the original mesh size (mean, 190 cm2 vs 225 cm2; mean reduction of mesh area, 35 cm2; P < .001). At 3 months postoperatively, a further reduction of the surface area due to significant mesh shrinkage could be observed (mean, 182 cm2 vs 190 cm2; mean reduction of mesh area, 8 cm2; P < .001). Conclusion: The new method of combining magnetic resonance imaging and meshes that provide enhanced signal capacity through direct integration of iron particles into the polyvinylidene fluoride base material allows for detailed mesh depiction and quantification of structural changes. In addition to a significant early postoperative decrease in effective mesh surface area, a further considerable reduction in size occurred within 3 months after implantation. PMID:25848195

Amyand's hernia is defined as protrusion of the vermiform appendix in an inguinal hernia sac. It is a rare entity with variable clinical presentation from normal vermiform appendix to abscess formation due to perforation of acute appendicitis. Although surgical treatment includes appendectomy and hernia repair, appendectomy in the absence of an inflamed appendix and use of a mesh in cases of appendectomy remain to be controversial. The aim of this study was to review the experience of mesh inguinal hernia repair plus appendectomy performed for Amyand's hernia with noninflamed appendices. There were five male patients with a mean age of 42.4 ± 16.1 years in this retrospective study in which Amyand's hernia was treated with mesh inguinal hernia repair plus appendectomy for noninflamed appendices. Patients with acute appendicitis and perforated vermiform appendix were excluded. There were four right sided and one bilateral inguinal hernia. Postoperative courses were uneventful. During the follow-up period (14.0 ± 7.7 months), there was no inguinal hernia recurrence. Mesh inguinal hernia repair with appendectomy can be performed for Amyand's hernia in the absence of acute appendicitis. However, presence of fibrous connections between the vermiform appendix and the surrounding hernia sac may be regarded as a parameter to perform appendectomy. PMID:28194430

Background: The use of meshes in hernia surgical repair promoted revolution in the surgical area; however, some difficulties had come, such as a large area of fibrosis, greater postoperative pain and risk of infection. The search for new substances that minimize these effects should be encouraged. Medicinal plants stand out due possible active ingredients that can act on these problems. Aim: To check the copaiba oil influence in the repair of abdominal defects in rats corrected with Vicryl(c) mesh. Method: Twenty-four Wistar rats were submitted to an abdominal defect and corrected with Vicryl(c) mesh. They were distributed into two groups: control and copaíba via gavage, administered for seven days after surgery. The analysis of the animals took place on 8, 15 and 22 postoperative days. It analyzed the amount of adhesions and microscopic analysis of the mesh. Results: There was no statistical difference regarding the amount of adhesions. All animals had signs of acute inflammation. In the control group, there were fewer macrophages in animals of the 8th compared to other days and greater amount of necrosis on day 8 than on day 22. In the copaiba group, the number of gigantocytes increased compared to the days analyzed. Conclusion: Copaiba oil showed an improvement in the inflammatory response accelerating its beginning; however, did not affect the amount of abdominal adhesions or collagen fibers. PMID:26537143

Background and Objectives: Despite the exponential increase in the use of laparoscopic inguinal herniorrhaphy, overall recurrence rates have remained unchanged. Therefore, a growing number of patients are presenting with recurrent hernias after conventional anterior and laparoscopic repairs have failed. This study reports our experience with single-incision laparoscopic (SIL) intraperitoneal onlay mesh (IPOM) repair of these hernias. Methods: Patients referred with two or more recurrences of inguinal hernia underwent SIL-IPOM from November 1, 2009, to June 24, 2014. A 2.5-cm infraumbilical incision was made, and an SIL port was placed intraperitoneally. Modified dissection techniques were used: chopstick and inline dissection, 5.5-mm/52-cm/30° angled laparoscope, and conventional straight dissecting instruments. The peritoneum was incised above the pubic symphysis, and dissection was continued laterally and proximally, raising the inferior flap below the previous extraperitoneal mesh while reducing any direct, indirect, femoral, or cord lipoma before placement of antiadhesive mesh, which was fixed to the pubic ramus, as well as superiorly, with nonabsorbable tacks before the inferior border was fixed with fibrin sealant. The inferior peritoneal flap was then tacked back onto the mesh. Results: Nine male patients underwent SIL-IPOM. Their mean age was 53 years and mean body mass index was 26.8 kg/m2. Mean mesh size was 275 cm2. Mean operation time was 125 minutes, with a hospital stay of 1 day. The umbilical scar length was 23 mm at the 6-week follow-up. There were no intra-/postoperative complications, port-site hernias, chronic groin pain, or recurrence of the hernia during a mean follow-up of 24 months. Conclusion: Inguinal hernias recurring after two or more failed conventional anterior and laparoscopic repairs can be safely and efficiently treated with SIL-IPOM. PMID:25848186

The influence of mesh material on the clinical outcome of hernia repair has often been neglected, although recent studies have clearly demonstrated the importance of mesh properties for integration in the abdominal wall. Of particular significance are the amount of mesh material and the pore size. In the following study, patients received different mesh types with distinct amounts of polypropylene and of various pore sizes for incisional hernia repair. We investigated whether the type of material influenced the clinical and functional outcomes. Between 1991 and 1999, 235 patients received polypropylene meshes in a sublay position for incisional hernia repair: 115 patients were implanted with a Marlex heavy-weight mesh (Mhw mesh), 37 patients with an Atrium heavy-weight mesh (Ahw mesh) and 83 with a Vypro low-weight mesh (Vlw mesh). The study protocol included ultrasound examination and 3D-stereography in all patients, with a total follow-up of 24 +/- 13 months (Mhw-mesh), 11 +/- 8 months (Ahw-mesh) and 8 +/- 7 months (Vlw-mesh). Our findings demonstrate that the side effects of mesh implantation, comprising paraesthesia and restriction of abdominal wall mobility, were significantly affected by the type of material implanted. Three-dimensional stereographic examinations were well in accordance with our clinical findings. Our data support the hypothesis that the use of low-weight large-pore meshes is advantageous for abdominal wall function.

Objective: We tested the hypothesis that laparoscopic inguinal herniorrhaphy using Surgisis mesh secured with fibrin sealant is an effective long-term treatment for repair of inguinal hernia. This case series involved 38 adult patients with 51 inguinal hernias treated in a primary care center. Methods: Between December 2002 and May 2005, 38 patients with 45 primary and 6 recurrent inguinal hernias were treated with laparoscopic repair by the total extra-peritoneal mesh placement (TEP) technique using Surgisis mesh secured into place with fibrin sealant. Postoperative complications, incidence of pain, and recurrence were recorded, as evaluated at 2 weeks, 6 weeks, 1 year, and with a follow-up questionnaire and telephone interview conducted in May and June 2005. Results: The operations were successfully performed on all patients with no complications or revisions to an open procedure. Average follow-up was 13 months (range, 1 to 30). One hernia recurred (second recurrence of unilateral direct hernia), indicating a 2% recurrence rate. Conclusions: Laparoscopic repair of inguinal hernia using Surgisis mesh secured with fibrin sealant can be effectively used to treat primary, recurrent, direct, indirect, and bilateral inguinal hernias in adults without complications and minimal recurrence within 1-year of follow-up.

Background and Objectives: Laparoscopic preperitoneal hernia repair with mesh has been reported to result in improved patient outcomes. However, there are few published data on the use of a totally extraperitoneal (TEP) approach. The purpose of this study was to present our experience and evaluate early outcomes of TEP inguinal hernia repair with self-adhesive mesh. Methods: This cohort study was a retrospective review of patients who underwent laparoscopic TEP inguinal hernial repair from April 4, 2010, through July 22, 2014. Data assessed were age, sex, body mass index (BMI), hernia repair indications, hernia type, pain, paresthesia, occurrence (bilateral or unilateral), recurrence, and patient satisfaction. Descriptive and regression analyses were performed. Results: Six hundred forty patients underwent laparoscopic preperitoneal hernia surgery with self-adhesive mesh. The average age was 56 years, nearly all were men (95.8%), and the mean BMI was 26.2 kg/m2. Cases involved primary hernia more frequently than recurrent hernia (94% vs 6%; P < .05). After surgery, 92% of the patients reported no more than minimal pain, <1% reported paresthesia, and 0.2% had early recurrence. There were 7 conversions to an open procedure. The patients had no adverse reactions to anesthesia and no bladder injury. Postoperative acute pain or recurrence was not explained by demographics, BMI, or preoperative pain. There were significant associations of hernia side, recurrence, occurrence, and sex with composite end points. Nearly all patients (98%) were satisfied with the outcome. Conclusion: The use of self-adhesive, Velcro-type mesh in laparoscopic TEP inguinal hernia repair is associated with reduced pain; low rates of early recurrence, infection, and hematoma; and improved patient satisfaction.

Introduction Laparoscopic incisional and ventral hernia repair (LIVHR) was first reported by Le Blanc and Booth in 1993. Many studies are available in the literature that have shown that laparoscopic repair of incisional and ventral hernia is preferred over open repair because of lower recurrence rates (less than 10%), less wound morbidity, less pain, and early return to work. Aim To identify the long-term outcomes between the different types of meshes and two techniques of mesh fixation, i.e., tacks (method Double crown) and transfascial polypropylene sutures. Material and methods A total of 92 patients underwent LIVHR at our department between January 2009 and August 2012. The hernias were umbilical in 26 patients, paraumbilical in 15 patients and incisional in 51 patients. All patients admitted for LIVHR were randomized to either group I (tacker fixation of ePTFE meshes) or group II (suture fixation of meshes with nitinol frame) using computer-generated random numbers with block randomization and sealed envelopes for concealed allocation. Results The mean mesh fixation time was significantly higher in the tacker fixation group (117 ±15 min vs. 72 ±6 min, p < 0.01). There were no conversions in either group. The median postoperative hospital stay was 3.5 ±1.5 days. All patients were followed up at 1, 3, 6, 12 and every 6 months thereafter postoperatively. There were 5 recurrences in the study population. In group I there were 4 patients with recurrence, and only 1 patient in the group with meshes with a nitinol frame. Conclusions Meshes of the new generation with a nitinol framework can significantly improve laparoscopic ventral hernia repair. The fixation of these meshes is very simple using 3–4 transfascial sutures. The absence of shrinkage of these meshes makes the probability of recurrence minimal. Absence of tackers allows postoperative pain to be minimized. We consider that these new meshes can significantly improve laparoscopic ventral hernia repair

Perineal hernia is an uncommon complication following abdominoperineal rectum resection. Several surgical procedures have been proposed for perineal hernia repair, including perineal, laparoscopic and abdominal approaches. Repair techniques can be classified into primary suture techniques, mesh placements and repairs with autogenous tissue. We report a 68-year-old man with a perineal hernia, who underwent a pelvic floor reconstruction with a transperineal composite mesh and a gluteal fasciocutaneous rotation flap. We conclude that a combined approach with transperineal mesh reconstruction and gluteal fasciocutaneous flap could be an alternative choice in perineal hernia repair after abdominoperineal resection.

The totally extraperitoneal (TEP) approach for surgical repair of inguinal hernias has emerged as a popular technique. We conducted a prospective randomised trial to compare patient comfort scores using different mesh types and fixation using this technique. Over a 14 month period, 146 patients underwent 232 TEP inguinal hernia repairs. We compared the comfort scores of patients who underwent these procedures using different types of mesh and fixation. A non-absorbable 15 × 10 cm anatomical mesh fixed with absorbable tacks (Control group) was compared with either a non-absorbable 15 × 10 cm folding slit mesh with absorbable tacks (Group 2), a partially-absorbable 15 × 10 cm mesh with absorbable tacks (Group 3) or a non-absorbable 15 × 10 cm anatomical mesh fixed with 2 ml fibrin sealant (Group 4). Outcomes were compared at 1, 2, 4 and 12 weeks using the Carolina Comfort Scale (CCS) scores. At 1, 2, 4 and 12 weeks, the median global CCS scores were low for all treatment groups. Statistically significant differences were seen only for median CCS scores and subscores with the use of partially-absorbable mesh with absorbable tacks (Group 3) at weeks 2 and 4. However, these were no longer significant at week 12. In this study, the TEP inguinal hernia repair with minimal fixation results in low CCS scores. There were no statistical differences in CCS scores when comparing types of mesh, configuration of the mesh or fixation methods.

In an attempt to find the ideal surgical technique for mesh fixation during laparoscopic total extraperitoneal inguinal hernia repair, we evaluate the use of a synthetic surgical glue (N-butyl-cyanoacrylate-Glubran 2) in an effort to reduce postoperative pain and the complications associated with the use of staples. We have prospectively evaluated 61 consecutive patients (73 hernias) with a minimum follow-up period of 18 months and an average of 29.7 months, without any significant complications present. The majority (59%) only required low dosages of painkillers during the first 24 hours after surgery and have not experienced any cases of chronic pain or recurring hernias in the time period described. On the basis of this initial experience, the use of the surgical glue used to repair inguinal hernias with the laparoscopic total extraperitoneal technique has been proved to be a simple and effective surgical method for mesh fixation.

Recurrence rate of hiatal hernia can be reduced with prosthetic mesh repair; however, type and shape of the mesh are still a matter of controversy. The purpose of this study was to investigate the biomechanical properties of four conventional meshes: pure polypropylene mesh (PP-P), polypropylene/poliglecaprone mesh (PP-U), polyvinylidenefluoride/polypropylene mesh (PVDF-I), and pure polyvinylidenefluoride mesh (PVDF-S). Meshes were tested either in warp direction (parallel to production direction) or perpendicular to the warp direction. A Zwick testing machine was used to measure elasticity and effective porosity of the textile probes. Stretching of the meshes in warp direction required forces that were up to 85-fold higher than the same elongation in perpendicular direction. Stretch stress led to loss of effective porosity in most meshes, except for PVDF-S. Biomechanical impact of the mesh was additionally evaluated in a hiatal hernia model. The different meshes were used either as rectangular patches or as circular meshes. Circular meshes led to a significant reinforcement of the hiatus, largely unaffected by the orientation of the warp fibers. In contrast, rectangular meshes provided a significant reinforcement only when warp fibers ran perpendicular to the crura. Anisotropic elasticity of prosthetic meshes should therefore be considered in hiatal closure with rectangular patches.

Introduction Lichtenstein’s tension free mesh hernioplasty is the commonly done open technique for inguinal hernias. As our hospital is in rural area, majority of patients are labourers, open hernias are commonly done. The present study was done by comparing Lichtenstein Mesh Repair (LMR) v/s Modified Bassini’s repair (MBR) + Lichtenstein mesh repair (LMR) of direct Inguinal Hernias to compare the technique of both surgeries and its outcome like postoperative complications and recurrence rate. Materials and Methods A comparative randomized study was conducted on patients reporting to MNR hospital, sangareddy with direct inguinal hernias. A total of fifty consecutive patients were included in this study of which, 25 patients were operated by LMR and 25 patients were operated by MBR+LMR and followed up for a period of two years. The outcomes of the both techniques were compared. Results Study involved 25 each of Lichtenstein’s mesh repair (LMR) and modified bassini’s repair (MBR) + LMR, over a period of 2 years. The duration of surgery for lichtenstein mesh repair is around 34.56 min compared to LMR+MBR, which is 47.56 min which was statistically significant (p-value is <0.0001). In this study the most common complication for both the groups was seroma. The pain was relatively higher in LMR+MBR group in POD 1, but not statistically significant (p-value is 0.0949) and from POD 7 the pain was almost similar in both groups. The recurrence rate is 2% for LMR and 0% for MBR+LMR. Conclusion LMR+MBR was comparatively better than only LMR in all direct inguinal hernias because of low recurrence rate (0%) and low postoperative complications, which showed in our present study.

There is no consensus on the ideal location for mesh placement in open ventral hernia repair (OVHR). We aim to identify the mesh location associated with the lowest rate of recurrence following OVHR using a systematic review and meta-analysis. A search was performed for studies comparing at least two of four locations for mesh placement during OVHR (onlay, inlay, sublay, and underlay). Outcomes assessed were hernia recurrence and surgical site infection (SSI). Pairwise meta-analysis was performed to compare all direct treatment of mesh locations. A multiple treatment meta-analysis was performed to compare all mesh locations in the Bayesian framework. Sensitivity analyses were planned for the following: studies with a low risk of bias, incisional hernias, by hernia size, and by mesh type (synthetic or biologic). Twenty-one studies were identified (n = 5,891). Sublay placement of mesh was associated with the lowest risk for recurrence [OR 0.218 (95% CI 0.06-0.47)] and was the best of the four treatment modalities assessed [Prob (best) = 94.2%]. Sublay was also associated with the lowest risk for SSI [OR 0.449 (95% CI 0.12-1.16)] and was the best of the 4 treatment modalities assessed [Prob (best) = 77.3%]. When only assessing studies at low risk of bias, of incisional hernias, and using synthetic mesh, the probability that sublay had the lowest rate of recurrence and SSI was high. Sublay mesh location has lower complication rates than other mesh locations. While additional randomized controlled trials are needed to validate these findings, this network meta-analysis suggests the probability of sublay being the best location for mesh placement is high.

Background: Fixation of the mesh during laparoscopic totally extraperitoneal (TEP) inguinal hernia repair is thought to be necessary to prevent recurrence. However, mesh fixation may increase postoperative pain and lead to an increased risk of complications. We questioned whether elimination of fixation of the mesh during TEP inguinal hernia repair leads to decreased postoperative pain or complications, or both, without an increased rate of recurrence. Methods: A randomized prospective single-blinded study was carried out in 40 patients who underwent laparoscopic TEP inguinal hernia repair with (Group A=20) or without (Group B=20) fixation of the mesh. Results: Patients in whom the mesh was not fixed had shorter hospital length of stay (8.3 vs 16.0 hours, P=0.01), were less likely to be admitted to the hospital (P=0.001), used less postoperative narcotic analgesia in the PACU (P=0.01), and were less likely to develop urinary retention (P=0.04). No significant differences occurred in the level of pain, time to return to normal activity, or the difficulty of the operation between the 2 groups. No hernia recurrences were observed in either group (follow-up range, 6 to 30 months, median=19). Conclusions: Elimination of tack fixation of mesh during laparoscopic TEP inguinal hernia repair significantly reduces the use of postoperative narcotic analgesia, hospital length of stay, and the development of postoperative urinary retention but does not lead to a significant reduction in postoperative pain. Eliminating tacks does not lead to an increased rate of recurrence. PMID:17575757

Antibiotic prophylaxis is being commonly used in mesh repair of inguinal hernia but its role has been questioned in a recent Cochrane analysis performed in 2003. Routine use of antibiotic prophylaxis in mesh repair of inguinal hernia can lead to bacterial resistance and increase in cost. In a present double-blind placebo controlled trial involving 120 patients undergoing inguinal hernia repair using prolene hernia system, we did not find any benefit of the routine use of antibiotic prophylaxis in terms of wound infection rate.

Laparoscopic inguinal hernia repair is now increasingly performed in bilateral and recurrent groin hernias. The avoidance of direct exposure of the commonly used meshes to the abdominal viscera is considered essential to reduce the risk of bowel adhesions. We report a case of bilateral inguinal hernia repair in a patients who had had an appendectomy performed 8 years earlier for a perforated appendicitis. Probably as a result of previous inflammation, any attempt to dissect the preperitoneal layer in the right side resulted in peritoneal lacerations. Since the peritoneum could not be used to cover the mesh, we decided to position an expanded polytetrafluoroethylene (e-PTFE) mesh to avoid postoperative adhesions. The mesh was fixed with tacks to the symphysis pubis, Cooper's ligament, the ilio-pubic tract, and the transversalis fascia 2 cm above the hernia defect. This case suggests that in patient with previous appendicitis, a difficult preperitoneal dissection can be expected. In such cases, especially in young patients for whom future surgical operations cannot be excluded, any attempt to reduce adhesions is justified. At the present time, the use of e-PTFE meshes, which induce no tissue reaction, is a good option in this situation.

INTRODUCTION Laparoscopic incisional and ventral hernia repair (LIVHR) is widely accepted and safe but the type of mesh used is still debated. We retrospectively compared postoperative outcomes with two different meshes commonly used in LIVHR. METHODS This is a retrospective study of patients who underwent incisional hernia repair between January 2008 and December 2010. Two meshes were used: Parietex™ Composite (Covidien, New Haven, CT, USA) and the DynaMesh(®)-IPOM (FEG Textiltechnik mbH, Aachen, Germany). The two groups were compared with respect to recurrence rates, incidence of seroma and intestinal obstruction. RESULTS Among the 88 patients who underwent LIVHR, 75 patients (85.2%) presented with primary incisional hernia, 10 (11.4%) presented with a first recurrence and 3 (3.4%) presented with a second recurrence. Median follow-up was 53.6 months (range 40-61 months). 12.9% of patients had recurrence in the Parietex™ Composite mesh group (n=62) in comparison to 3.8% in the DynaMesh(®)-IPOM mesh group (n=26; P=0.20). DynaMesh(®)-IPOM was associated with a significantly higher incidence of intestinal obstruction secondary to adhesions (11.5% vs. 0%, P=0.006) and lower incidence of seroma and haematoma formation compared to Parietex™ composite mesh group (0% vs. 6.4% of patients; P=0.185). CONCLUSIONS LIVHR is a safe and feasible technique. Dynamesh(®)-IPOM is associated with a significantly higher incidence of adhesion related bowel obstruction, albeit with a lower incidence of recurrence, seroma and haematoma formation compared with Parietex™ Composite mesh. However, there is a need for further well-designed, multicentre randomised controlled studies to investigate the use of these meshes.

During the past few years, biologic meshes, primarily evolved for routine and complex cases of abdominal wall reconstruction, have been evaluated in clinical cases and experimental models. Although there is published experience on the use of small intestine submucosa and human cadaveric dermis in hiatal hernia repair with encouraging results, porcine dermal collagen (PDC) matrix has not been subject of study to date in this patient population. A systematic review of the literature was conducted, aiming at evaluating the biomechanical characteristics of cross-linked PDC in comparison to synthetic and biologic meshes. Evidence shows that cross-linked PDC is superior to synthetic meshes in terms of incorporation, adhesion formation, and mesh fibrosis; their biodynamic and biotechnical characteristics do not seem to be superior to other bioprosthetic materials according to current data. The clinical and experimental results of cross-linked PDC implants justify their pilot clinical evaluation in hiatal hernia patients.

Introduction: Despite an exponential rise in laparoscopic surgery for inguinal herniorrhaphy, overall recurrence rates have remained unchanged. Therefore, an increasing number of patients present with recurrent hernias after having failed anterior and laparoscopic repairs. This study reports our experience with single-incision laparoscopic (SIL) intraperitoneal onlay mesh (IPOM) repair for these hernias. Materials and methods: All patients referred with multiply recurrent inguinal hernias underwent SIL-IPOM from November 1 2009 to October 30 2013. A 2.5-cm infraumbilical incision was made and a SIL surgical port was placed intraperitoneally. Modified dissection techniques, namely, “chopsticks” and “inline” dissection, 5.5 mm/52 cm/30° angled laparoscope and conventional straight dissecting instruments were used. The peritoneum was incised above the symphysis pubis and dissection continued laterally and proximally raising an inferior flap, below a previous extraperitoneal mesh, while reducing any direct/indirect/femoral/cord lipoma before placement of antiadhesive mesh that was fixed into the pubic ramus as well as superiorly with nonabsorbable tacks before fixing its inferior border with fibrin sealant. The inferior peritoneal flap was then tacked back onto the mesh. Results: There were 9 male patients who underwent SIL-IPOM. Mean age was 55 years old and mean body mass index was 26.8 kg/m2. Mean mesh size was 275 cm2. Mean operation time was 125 minutes with hospital stay of 1 day and umbilical scar length of 21 mm at 4 weeks' follow-up. There were no intraoperative/postoperative complications, port-site hernias, chronic groin pain, or recurrence with mean follow-up of 20 months. Conclusions: Multiply recurrent inguinal hernias after failed conventional anterior and laparoscopic repairs can be treated safely and efficiently with SIL-IPOM. PMID:25392643

We present two cases of laparoscopically inserted mesh for inguinal hernia repair that became infected following emergency open bowel surgery. We believe that there is an increased risk of infection due to the larger size of mesh used in the laparoscopic repair but also due to the patient not volunteering the information because of the minimally invasive nature of the procedure.

Aim. Although inguinal hernia repair is the most frequently performed surgical procedure in the world, the best repair method has not gained acceptance yet. The ideal repair must be safe, simple, and easy to perform and require minimal dissection which provides enough exploration, maintain patient's comfort in the early stage, and also be cost-effective, reducing operation costs, labor loss, hospital stay, and recurrence. Materials and Methods. There were eighty-five patients between the ages of 18 and 75, diagnosed with inguinal hernia in our clinic. Lichtenstein procedure for hernia repair was performed under spinal anesthesia in all patients. Forty-two patients had the standard procedure and, in 43 patients, the polypropylene mesh was used without fixation. All patients were examined and questioned on the 7th day of the operation in terms of pain, scrotal edema, and the presence of seroma and later on in the 6th postoperative month in terms of paresthesia, neuropraxia, and recurrence by a single physician. Results. Operative time and pain scores in the nonfixation group were significantly lower, without any increase in rates of recurrence. Conclusion. Based on these findings, in Lichtenstein hernia repair method, nonfixation technique can be used safely with better results. PMID:27200411

AIM: To compare long term outcomes of laparoscopic and open ventral hernia mesh repair with respect to recurrence, pain and satisfaction. METHODS: We conducted a single-centre follow-up study of 194 consecutive patients after laparoscopic and open ventral hernia mesh repair between March 2000 and June 2010. Of these, 27 patients (13.9%) died and 12 (6.2%) failed to attend their follow-up appointment. One hundred and fifty-three (78.9%) patients attended for follow-up and two patients (1.0%) were interviewed by telephone. Of those who attended the follow-up appointment, 82 (52.9%) patients had received laparoscopic ventral hernia mesh repair (LVHR) while 73 (47.1%) patients had undergone open ventral hernia mesh repair (OVHR), including 11 conversions. The follow-up study included analyses of medical records, clinical interviews, examination of hernia recurrence and assessment of pain using a 100 mm visual analogue scale (VAS) ruler anchored by word descriptors. Overall patient satisfaction was also determined. Patients with signs of recurrence were examined by magnetic resonance imaging or computed tomography scan. RESULTS: Median time from hernia mesh repair to follow-up was 48 and 52 mo after LVHR and OVHR respectively. Overall recurrence rates were 17.1% after LVHR and 23.3% after OVHR. Recurrence after LVHR was associated with higher body mass index. Smoking was associated with recurrence after OVHR. Chronic pain (VAS > 30 mm) was reported by 23.5% in the laparoscopic cohort and by 27.8% in the open surgery cohort. Recurrence and late complications were predictors of chronic pain after LVHR. Smoking was associated with chronic pain after OVHR. Sixty point five percent were satisfied with the outcome after LVHR and 49.3% after OVHR. Predictors for satisfaction were absence of chronic pain and recurrence. Old age and short time to follow-up also predicted satisfaction after LVHR. CONCLUSION: LVHR and OVHR give similar long term results for recurrence, pain and

Introduction: Adhesions to mesh/tacks in laparoscopic ventral hernia repair are often cited as reasons not to adopt its evidence-based superiority over conventional open methods. This pilot study assessed the occurrence of adhesions to full-sized Polypropylene and Gore-tex DualMesh Plus meshes and the possibility for adhesion prevention using fibrin sealant. Methods: Two 10-cm to 15-cm pieces of mesh were placed and fixed laparoscopically in pigs (25kg to 55kg). Group I: 2 animals with Polypropylene mesh on one side and DualMesh on other side. Group II: 2 animals with DualMesh on each side with fibrin sealant applied to the periphery of mesh and staples to one side. Group III: 1 animal with 2 pieces of Polypropylene mesh with fibrin sealant applied to the entire mesh. All animals underwent laparoscopy 3 months later to assess the extent of adhesions, and full-thickness specimens were removed for histological evaluation. Results: More Polypropylene mesh was involved in adhesions than DualMesh. However, with the DualMesh involved in adhesions, more of the surface area was involved in forming adhesions than with Polypropylene mesh. None of the implanted DualMesh had visceral adhesions, while 2 out of 3 Polypropylene meshes had adhesions to both the liver and spleen but none to the bowel. Implanted Polypropylene mesh with fibrin sealant had no adhesions. DualMesh had shrunk more significantly than Polypropylene mesh. Histological evaluation showed absence of acute inflammatory response, significantly more chronic inflammatory response to DualMesh compared to Polypropylene and complete mesothelialization with both meshes. There was extensive collagen deposition between Polypropylene mesh fibers, while fibrosis occurred on both sides of DualMesh with synovial metaplasia over its peritoneal surface akin to encapsulation. Conclusions: DualMesh caused fewer omental and visceral adhesions than Polypropylene mesh did. Fibrin sealant eliminated adhesions to DualMesh and

Background Hernia repair is the most common surgical procedure in the world. Augmentation with synthetic meshes has gained importance in recent decades. Most of the published work about hernia meshes focuses on the surgical technique, outcome in terms of mortality and morbidity and the recurrence rate. Appropriate biomechanical and engineering terminology is frequently absent. Meshes are under continuous development but there is little knowledge in the public domain about their mechanical properties. In the presented experimental study we investigated the mechanical properties of several widely available meshes according to German Industrial Standards (DIN ISO). Methodology/Principal Findings Six different meshes were assessed considering longitudinal and transverse direction in a uni-axial tensile test. Based on the force/displacement curve, the maximum force, breaking strain, and stiffness were computed. According to the maximum force the values were assigned to the groups weak and strong to determine a base for comparison. We discovered differences in the maximum force (11.1±6.4 to 100.9±9.4 N/cm), stiffness (0.3±0.1 to 4.6±0.5 N/mm), and breaking strain (150±6% to 340±20%) considering the direction of tension. Conclusions/Significance The measured stiffness and breaking strength vary widely among available mesh materials for hernia repair, and most of the materials show significant anisotropy in their mechanical behavior. Considering the forces present in the abdominal wall, our results suggest that some meshes should be implanted in an appropriate orientation, and that information regarding the directionality of their mechanical properties should be provided by the manufacturers.

Ventral hernia repair remains a major clinical need. Herein, we formulated a type I collagen/elastin crosslinked blend (CollE) for the fabrication of biomimetic meshes for ventral hernia repair. To evaluate the effect of architecture on the performance of the implants, CollE was formulated both as flat sheets (CollE Sheets) and porous scaffolds (CollE Scaffolds). The morphology, hydrophylicity and in vitro degradation were assessed by SEM, water contact angle and differential scanning calorimetry, respectively. The stiffness of the meshes was determined using a constant stretch rate uniaxial tensile test, and compared to that of native tissue. CollE Sheets and Scaffolds were tested in vitro with human bone marrow-derived mesenchymal stem cells (h-BM-MSC), and finally implanted in a rat ventral hernia model. Neovascularization and tissue regeneration within the implants was evaluated at 6weeks, by histology, immunofluorescence, and q-PCR. It was found that CollE Sheets and Scaffolds were not only biomechanically sturdy enough to provide immediate repair of the hernia defect, but also promoted tissue restoration in only 6weeks. In fact, the presence of elastin enhanced the neovascularization in both sheets and scaffolds. Overall, CollE Scaffolds displayed mechanical properties more closely resembling those of native tissue, and induced higher gene expression of the entire marker genes tested, associated with de novo matrix deposition, angiogenesis, adipogenesis and skeletal muscles, compared to CollE Sheets. Altogether, this data suggests that the improved mechanical properties and bioactivity of CollE Sheets and Scaffolds make them valuable candidates for applications of ventral hernia repair.

Incisional ventral hernias are a common problem encountered by surgeons, with over 100,000 repairs being performed annually in the United States. Although many predisposing factors for incisional ventral hernia are patient-related, some factors such as type of primary closure and materials used may reduce the overall incidence of incisional ventral hernia. With the advent of prosthetic meshes being used for incisional ventral hernia repair, the recurrence rate has dropped to approximately 10%. More recently, with the development of prosthetic mesh that is now safe to place intraperitoneally, the recurrence rate has dropped to under 5%. The current controversies that exist for incisional ventral hernia repair are which approach to use (open versus laparoscopic) and what type of fixation (partial- versus full-thickness abdominal muscular/fascial wall) is necessary to stabilize the position of the mesh while tissue ingrowth occurs. During the next decade the answers to these controversies should be available in the surgical literature.

Abstract Acute renal failure due to ureter compression after a mesh-plug inguinal repair in a kidney transplant recipient has not been previously reported to our knowledge. A 62-year-old man, who successfully underwent kidney transplantation from a deceased donor 6 years earlier, was admitted for elective repair of a direct inguinal hernia. The patient underwent an open mesh-plug repair of the inguinal hernia with placement of a plug in the preperitoneal space. We did not observe the transplanted ureter and bladder during dissection of the inguinal canal. Immediately after surgery, the patient became anuric, and a graft sonography demonstrated massive hydronephrosis. The serum creatinine level increased rapidly, and the patient underwent an emergency reoperation 8 hours later. During surgery, we did not identify the ureter but, immediately after plug removal, urine output increased progressively. We completed the hernia repair using the standard technique, without plug interposition, and the postoperative course was uneventful with complete resolution of graft dysfunction 3 days later. Furthermore, we reviewed the clinical features of complications related to inguinal hernia surgery. An increased risk of urological complications was reported recently in patients with a previous prosthetic hernia repair undergoing kidney transplantation, mainly due to the mesh adhesion to surrounding structures, making the extraperitoneal dissection during the transplant surgery very challenging. Moreover, older male kidney transplant recipients undergoing an inguinal hernia repair may be at higher risk of graft dysfunction due to inguinal herniation of a transplanted ureter. Mesh-plug inguinal hernia repair is a safe surgical technique, but this unique case suggests that kidney transplant recipients with inguinal hernia may be at higher risk of serious urological complications. Surgeons must be aware of the graft and ureter position before proceeding with hernia repair. A prompt

Use of mosquito net, in place of polypropylene mesh, had been reported for tension-free hernia repair, as a better cost-effective option. This experimental histopathological study was performed in rats to find out the tissue response and the foreign body reaction and its comparison between commercial polypropylene mesh and the sterilized mosquito net. This experimental study was conducted in the Department of Surgery, Government NSCB, Medical College, Jabalpur (Madhya Pradesh), India. It was carried out in 40 albino rats. A 1.5 × 0.5-cm hernial defect was created by excising full-thickness abdominal wall muscle. All rats underwent on-lay mesh repair of hernial defect (polypropylene mesh, n = 20; mosquito net, n = 20). Half of rats in each group were sacrificed on day 14, and the other half, on day 90. Sections of containing mesh were examined histopathologically for inflammatory infiltrate, giant cells, and collagen deposition. Mosquito net group showed significantly greater number of giant cells and inflammatory cells at 14 and 90 days (p < 0.0001, p < 0.001, p < 0.05, and p < 0.001, respectively), as compared to polypropylene group. Grades of collagen fiber deposition were almost equal in both groups, both at 14 and 90 days (p > 0.05 and p > 0.05, respectively). Results of mosquito net are comparable to conventional polypropylene mesh. In a setup, where cost-effectiveness is of primary importance, use of mosquito net for tension-free hernia repair can be an acceptable alternative as proven histologically, to commercially available polypropylene mesh.

Mesh erosion into visceral organs is a rare complication following laparoscopic mesh repair for inguinal hernia with only 15 cases reported in English literature. We report the first case of complete laparoscopic management of mesh erosion into small bowel and urinary bladder. A 62-year-male underwent laparoscopic total extra-peritoneal repair of left inguinal hernia at another centre in April 2012. He presented to our centre 21 months later with persistent lower urinary tract infection (UTI). On evaluation mesh erosion into bowel and urinary bladder was suspected. At laparoscopy, a small bowel loop was adhered to the area of inflammation in the left lower abdomen. After adhesiolysis, mesh was seen to be eroding into small bowel. The entire infected mesh was pulled out from the pre-peritoneal space and urinary bladder wall using gentle traction. The involved small bowel segment was resected, and bowel continuity restored using endoscopic linear cutter. The resected bowel along with the mesh was extracted in a plastic bag. Intra-operative test for leak from urinary bladder was found to be negative. The patient recovered uneventfully and is doing well at 12 months follow-up with resolution of UTI. Laparoscopic approach to mesh erosion is feasible as the plane of mesh placement during laparoscopic hernia repair is closer to peritoneum than during open hernia repair. PMID:26917927

We present a case of a man admitted to our Hospital for right acute scrotum that six months before had undergone a right hernioplasty with mesh implantation. Clinical history and testicular color Doppler sonography (CDS) patterns suggested an orchiepididymitis following acute prostatitis. After 48h the clinical picture worsened and testicular CDS showed a decreased telediastolic velocity that suggested testicular ischemia. The patient underwent surgical exploration: spermatic cord appeared stretched by an inflammatory tissue in absence of torsion and releasing of spermatic cord was performed. In patients with genitourinary infection who previously underwent inguinal mesh implantation, testicular CDS follow-up is mandatory. PMID:19718342

Introduction: Spigelian hernia is an uncommon ventral hernia characterized by a defect in the linea semilunaris. Repair of spigelian hernia has traditionally been accomplished via an open transverse incision and primary repair. The purpose of this article is to present 2 case reports of incarcerated spigelian hernia that were successfully repaired laparoscopically using Gortex mesh and to present a review of the literature regarding laparoscopic repair of spigelian hernias. Methods: Retrospective chart review and Medline literature search. Results: Two patients underwent laparoscopic mesh repair of incarcerated spigelian hernias. Both were started on a regular diet on postoperative day 1 and discharged on postoperative days 2 and 3. One patient developed a seroma that resolved without intervention. There was complete resolution of preoperative symptoms at the 12-month follow-up. Conclusion: Minimally invasive repair of spigelian hernias is an alternative to the traditional open surgical technique. Further studies are needed to directly compare the open and the laparoscopic repair. PMID:19660230

Background The aim of our study was to determine an influence of incarcerated inguinal hernia mesh repair on testicular circulation and to investigate consequent sperm autoimmunity as a possible reason for infertility. Material/Methods This prospective study was performed over a 3-year period, and 50 male patients were included; 25 of these patients underwent elective open mesh hernia repair (Group I). Group II consisted of 25 patients who had surgery for incarcerated inguinal hernia. Doppler ultrasound evaluation of the testicular blood flow and blood samplings for antisperm antibodies (ASA) was performed in all patients before the surgery, on the second day, and 5 months after. Main outcome ultrasound measures were resistive index (RI) and pulsative index (PI), as their values are inversely proportional to testicular blood flow. Results In Group I, RI, and PI temporarily increased after surgery and then returned to basal values in the late postoperative period. Friedman analysis showed a significant difference in RI and PI for all measurements in Group II (p<0.05), with a significant decrease between the preoperative, early, and late postoperative periods. All final values were within reference range, including ASA, despite significant increase of ASA in the late postoperative period. Conclusions Although statistically significant differences in values of testicular flow parameters and immunologic sensitization in observed time, final values remained within the reference ranges in all patients. Our results suggest that the polypropylene mesh probably does not cause any clinically significant effect on testicular flow and immunologic response in both groups of patients. PMID:27149257

Introduction The Lichtenstein technique is commonly used in inguinal hernia repair and a polypropylene mesh is the most frequently used mesh. Mesh migration into the colon has been rarely reported in the literature. Here we report a case of a colocutaneous fistula that developed following delayed mesh migration into the sigmoid colon. Presentation of case A 52-year-old man undergone Lichtenstein repair for left direct inguinal herniain 2008. Three years later, he presented complaining of rectal bleeding and concurrent bloody discharge from the hernia repair scar. Colonoscopy identified an internal fistulous orifice with intraluminal extrusion of the polypropylene mesh. Furthermore, abdominal ultrasound revealed a fistulous tract extending from the sigmoid colon to the anterior abdominal wall, and a fistulogram confirmed the findings. Open sigmoidectomy and resection of the abdominal wall with the fistula tract was performed, and BIO-A® tissue reinforcement meshwas placed. His postoperative course was unremarkable and was discharged on postoperative day 3. Discussion Mesh migration after mesh inguinal hernia repair is unpredictable. A previous report has presented complications related to prosthetics in hernia repair, such as infection, contraction, rejection, and, rarely, mesh migration.Mesh migration may occur as an early or late complication after hernioplasty. Conclusion During hernia repair, the surgeon should carefully check for a sliding hernia, which may contain the sigmoid colon within the sac, because failure to identify this hernia may lead to direct contact between the mesh and the colon, which may cause pressure necrosis and fistula formation followed by mesh migration.

The technical problems, early complications and short-term results of a tension-free method of 1098 inguinal hernia repairs in 1017 patients have been assessed. The operation was conducted under local anaesthesia, and the inguinal canal floor was reinforced by a polypropylene mesh. Patients were discharged home the same day. There was no mortality, no urinary complications and one case of venous thrombosis. There was one recurrence after a primary hernia repair and two patients have developed recurrences after repair of a recurrent hernia. The overall sepsis rate was 0.9% and 1% of patients had persistent neuralgia. No prosthesis required removal. In all, 49.6% of office workers returned to work in 1 week or less and 61% of manual workers in 2 weeks or less. The major advantages of the tension-free mesh repair under local anaesthesia are simplicity, substantial cost savings and very low rates of complications. PMID:7574324

Aim. The aim of the present study was to perform MRI in patients after ventral hernia mesh repair, in order to evaluate MRI's ability to detect intra-abdominal adhesions. Materials and Methods. Single-center long term follow-up study of 155 patients operated for ventral hernia with laparoscopic (LVHR) or open mesh repair (OVHR), including analyzing medical records, clinical investigation with patient-reported pain (VAS-scale), and MRI. MRI was performed in 124 patients: 114 patients (74%) after follow-up, and 10 patients referred for late complaints after ventral mesh repair. To verify the MRI-diagnosis of adhesions, laparoscopy was performed after MRI in a cohort of 20 patients. Results. MRI detected adhesions between bowel and abdominal wall/mesh in 60% of the patients and mesh shrinkage in 20–50%. Adhesions were demonstrated to all types of meshes after both LVHR and OVHR with a sensitivity of 70%, specificity of 75%, positive predictive value of 78%, and negative predictive value of 67%. Independent predictors for formation of adhesions were mesh area as determined by MRI and Charlson index. The presence of adhesions was not associated with more pain. Conclusion. MRI can detect adhesions between bowel and abdominal wall in a fair reliable way. Adhesions are formed both after open and laparoscopic hernia mesh repair and are not associated with chronic pain.

Using mesh or a synthetic prosthesis during tension-free inguinal hernia repair has been shown to be safe and effective. We compared the final outcome in treating inguinal hernia in 45 patients using three different prosthetic materials: 15 patients underwent tension-free inguinal hernia repair using Prolene (polypropylene) mesh, 15 using Vypro (polyglactin and polypropylene) mesh, and 15 with Surgisis-a new bioactive material derived from porcine small intestinal submucosa. The aim of this study was to evaluate the safety and efficacy of tension-free inguinal repair using Surgisis, comparing it with conventional prosthetic materials. From January 2003 to December 2003, 45 male patients underwent Lichtenstein inguinal hernia repair. Median follow-up was 12 months, with a range of 1-16 months. Each patient underwent ultrasound evaluation of the inguinal region 1 month after surgery. All the procedures were completed under local anesthesia. There were no intraoperative complications, and all patients were discharged home the same day of surgery. No recurrent hernias and wound infections were observed in our post-operative follow-up period. Postoperative pain (visual analog score) and discomfort were lower in patients with Surgisis mesh. There was no statistically significant difference between the groups in terms of overall early and late complications; however, there was a tendency toward a higher incidence of pain and discomfort in Vypro and Prolene group. The median time to full recovery was significantly shorter in the Surgisis group. Surgisis mesh seems to be a promising new prosthetic material for hernia repair. Long-term follow-up is necessary to confirm these preliminary results.

OBJECTIVE: This study was done (1) to determine whether congenital indirect inguinal hernias in male pigs could be repaired by placing a polypropylene mesh prosthesis over the defect intra-abdominally, (2) to measure the incidence of adhesions between intra-abdominal viscera and the prosthesis with and without the adhesion barrier oxidized regenerated cellulose, (3) to determine the incidence of other complications, and (4) to assess the effect on fertility. SUMMARY BACKGROUND DATA: Several techniques for laparoscopic inguinal herniorrhaphy are currently being evaluated to determine whether there are advantages over conventional inguinal herniorrhaphy. Perhaps the most controversial is the intraperitoneal onlay mesh procedure (IPOM). Its advantage is its simplicity (in that the repair is accomplished by placing a prosthesis over the hernia defect intra-abdominally, avoiding a groin dissection). Its disadvantage is the potential for complications because the prosthesis is in contact with the intra-abdominal viscera. METHODS: In male pigs, polypropylene mesh alone or polypropylene mesh plus the adhesion barrier oxidized regenerated cellulose (composite prosthesis) was fixed to the peritoneum surrounding the hernia defect. In phase 1 (6-week follow-up), two groups of 13 pigs each underwent herniorrhaphy at laparotomy or laparoscopy. In phase 2 (7.1-month follow-up), 21 pigs underwent laparoscopic herniorrhaphy. RESULTS: All IPOM herniorrhaphies were successful. The prostheses adhered most frequently to the bladder, followed by small bowel, peritoneum, and cord structures. Prosthetic erosion into these organs was not observed. Laparoscopically placed prostheses in phases 1 and 2 had significantly less surface covered by adhesions (13% +/- 13% and 19% +/- 27%, respectively) and a lower adhesion tenacity grade (1.5 +/- 0.9 and 1.3 +/- 1.1, respectively) than those placed at laparotomy (44% +/- 27% and 2.5 +/- 0.7, respectively; p < 0.01). In phase 1, a histologic

Traumatic or postsurgical flank hernias are complex and prone to recurrence, particularly at the border of the iliac crest. We reviewed our experience using suture anchors drilled into the iliac crest to fixate the mesh to bone. Our study of 10 repairs in eight patients was Institutional Review Board exempt. We obtained demographics, body mass index, diabetes, methicillin-resistant Staphylococcus aureus (MRSA) history, smoking status, steroid use, number of prior repairs, defect size, mesh size, number of anchors, and recurrence and infection at follow-up. We performed Kaplan-Meier analysis using a composite of recurrence or infection. Three of eight (interquartile range, 37.5%) patients were male. Median age and body mass index were 47.5 years (31.0, 54.7) and 32.2 (29.0, 36.0), respectively. Three patients had prior repairs, one each with two, three, and five prior attempts at fixation. One of eight patients (12.5%) had a history of MRSA infection. One of eight patients (12.5%) had a history of intermittent steroid use for sarcoidosis. Defect size was 90 cm2 (62.2, 165) and mesh size was 155 cm2 (150, 232) with four anchors (4, 5.5). Procedural complications included 2/10 (20%) with recurrence and 1/10 (10%) with postoperative MRSA infection. Follow-up was 12 months (3.0, 25.0). Mean freedom from recurrence and mesh infection (Kaplan-Meier) was 43.5 months (95%confidence interval = 24.2, 62.8). In conclusion, our series is one of the largest in the literature involving the suture anchor technique. Despite a high-risk patient population due to trauma, obesity, and prior smoking and MRSA history, we achieved an acceptable recurrence rate. Further study may benefit from a randomized trial design.

In this study, efficacy of two hernia mesh implants viz. conventional Prolene and a novel Prolene-Vicryl composite mesh was assessed for experimental ventral hernia repair in dogs. Twelve healthy mongrel dogs were selected and randomly divided into three groups, A, Band C (n=4). In all groups, an experimental laparotomy was performed; thereafter, the posterior rectus sheath and peritoneum were sutured together, while, a 5 × 5 cm defect was created in the rectus muscle belly and anterior rectus sheath. For sublay hernioplasty, the hernia mesh (Prolene: group A; Prolene-Vicryl composite mesh: group B), was implanted over the posterior rectus sheath. In group C (control), mesh was not implanted; instead the laparotomy incision was closed after a herniorrhaphy. Post-operative pain, mesh shrinkage and adhesion formation were assessed as short term complications. Post-operatively, pain at surgical site was significantly less (P<0.001) in group B (composite mesh); mesh shrinkage was also significantly less in group B (21.42%, P<0.05) than in group A (Prolene mesh shrinkage: 58.18%). Group B (composite mesh) also depicted less than 25% adhesions (Mean ± SE: 0.75 ± 0.50 scores, P≤0.013) when assessed on the basis of a Quantitative Modified Diamond scale; a Qualitative Adhesion Tenacity scale also depicted either no adhesions (n=2), or, only flimsy adhesions (n=2) in group B (composite mesh), in contrast to group A (Prolene), which manifested greater adhesion formation and presence of dense adhesions requiring blunt dissection. Conclusively, the Prolene-Vicryl composite mesh proved superior to the Prolene mesh regarding lesser mesh contraction, fewer adhesions and no short-term follow-up complications.

Abstract Laparoscopic transabdominal preperitoneal inguinal hernia repair is a safe and effective technique. In this study we tested the hypothesis that self-gripping mesh used with the laparoscopic approach is comparable to polypropylene mesh in terms of perioperative complications, against a lower overall cost of the procedure. We carried out a prospective randomized trial comparing a group of 30 patients who underwent laparoscopic inguinal hernia repair with self-gripping mesh versus a group of 30 patients who received polypropylene mesh with fibrin glue fixation. There were no statistically significant differences between the two groups with regard to intraoperative variables, early or late intraoperative complications, chronic pain or recurrence. Self-gripping mesh in transabdominal hernia repair was found to be a valid alternative to polypropylene mesh in terms of complications, recurrence and postoperative pain. The cost analysis and comparability of outcomes support the preferential use of self-gripping mesh. PMID:28352842

The article deals with a comparative analysis of the parameters of the polymerization in physiological conditions of three commercially available alkyl cyanoacrylates, n-butyl cyanoacrylate (GLUBRAN 2), n-hexyl cyanoacrylate (IFABOND), and n-octyl cyanoacrylate (EVOBOND), the cell behavior of the corresponding polymers and the application of these adhesives in the fixation of surgical polypropylene meshes for hernia repair in an animal model of rabbits. The results obtained demonstrate that the curing process depends on the nature of the alkyl residue of the ester group of cyanoacrylate molecules, being the heat of polymerization lower for the octyl derivative in comparison with the hexyl and butyl, and reaching a maximum temperature of 35 °C after a time of mixing with physiological fluids of 60-70 s. The cell behavior demonstrates that the three systems do not present toxicity for fibroblasts and low adhesion of cells, which is a positive result for application as tissue adhesives, especially for the fixation of abdominal polypropylene meshes for hernia repair. The animal experimentation indicates the excellent tolerance of the meshes fixed with the cyanoacrylic adhesives, during at least a period of 90 d, and guarantees a good adhesion for the application of hernia repair meshes.

The purpose of this study was to compare a lightweight mesh to a standard polypropylene hernia mesh in endoscopic extraperitoneal hernioplasty in recurrent hernias. A total of 140 men with recurrent unilateral inguinal hernias were randomised to a totally extraperitoneal endoscopic hernioplasty (TEP) with Prolene or VyproII in a single-blinded multi-center trial. The randomisation and all data handling were performed through the Internet. 137 patients were operated as allocated. Follow-up was completed in 88% of the patients. The median operation times were 55 (24-125) min and 53.5 (21-123) min for the Prolene and VyproII groups, respectively. The meshes had comparable results in the surgeon's assessment of the handling of the mesh, return to work, return to daily activities, complications, postoperative pain and quality of life during the first 8 weeks of rehabilitation, except in General Health (GH) SF-36, where the VyproII-group had a significantly better score (P=0.045). The use of Prolene and VyproII-meshes in endoscopic repair of recurrent inguinal hernia seems to result in similar short-term outcomes and quality of life.
A 9-month-old female baby was brought to our hospital with a large ventral hernia which had developed after conservative treatment of an exomphalos. A hitherto undescribed technique involving serial tightening of a Prolene mesh was utilised to close the ventral hernia. We were able to achieve a good result within a short period of 2 weeks, without resorting to ventilation. We propose this procedure as an alternative to other existing techniques in similar situations.

Mesh hiatoplasty has been postulated to reduce recurrence rates, it is however prone to esophageal stricture, and early-term and mid-term dysphagia. The present meta-analysis was designed to compare the outcome between mesh-reinforced and primary hiatal hernia repair. The databases of Medline, EMBASE, and the Cochrane Library were searched; only randomized controlled trials entered the meta-analytical model. Anatomic recurrence documented by barium oesophagography was defined as the primary outcome endpoint. Three randomized controlled trials reporting the outcomes of 267 patients were identified. The follow-up period ranged between 6 and 12 months. The weighted mean recurrence rates after primary and mesh-reinforced hiatoplasty were 24.3% and 5.8%, respectively. Pooled analysis demonstrated increased risk of recurrence in primary hiatal closure (odds ratio, 4.2; 95% confidence interval, 1.8-9.5; P=0.001). Mesh-reinforced hiatal hernia repair is associated with an approximately 4-fold decreased risk of recurrence in comparison with simple repair. The long-term results of mesh-augmented hiatal closure remain to be investigated.

INTRODUCTION: Inguinal hernia repair is one of the most frequently performed surgical procedures worldwide in general surgery. The transabdominal laparoscopic (TAPP) approach in the therapy of inguinal hernia seems to be a suitable alternative to classical open inguinal hernia repair mainly in the hands of an experienced surgeon. TAPP repair offers the possibility of gentle dissection with implantation of the mesh and the possibility of non-invasive fixation of the implanted mesh. MATERIALS AND METHODS: Data analysis encompassed all patients who underwent inguinal hernia surgery at our Surgical Department within the period from July 1, 2012 to September 30, 2014 and who fulfilled the inclusion criteria. The standard surgical technique was used. Data were entered and subsequently analysed on the Herniamed platform. Herniamed is an Internet-based register in German and English, and includes all data of outpatient and hospitalised patients who underwent surgery for some type of hernia. All relevant patient data are collected via Internet. RESULTS: There were 241 patients enrolled in the group and there were 396 inguinal hernias repaired in total. Standard long-term follow-up after 12 months was evaluated in 205 patients (85.06%), and in the rest of the patients during the closing of the study, but at least 6 months after operation. The mean follow-up was at 19.69 months. At the 1-year assessment, mild discomfort was reported in the groin in 10 patients (4.88%) [1-3 on the visual analogue scale (VAS)]. Post-operative pain lasting over 12 months in the groin of moderate degree (4-6 VAS) was reported in two cases (0.97%). There was no recurrence and no chronic post-operative pain of severe degree reported. CONCLUSION: Our study demonstrates that laparoscopic inguinal hernia repair using the TAPP technique with the implantation of a self-fixation mesh is fast, effective, reliable and economically advantageous method in experienced hands and, according to our results

Although laparoscopic repair offers a quick and less morbid way of treating hernias, complications like hematoma, seroma, neuralgia, recurrence, mesh infection, hydrocele, etc. are known. The present study was undertaken to compare various clinical outcomes between mesh fixation using fibrin glue and mesh fixation with tacker in a 3-months follow-up. One hundred patients aged 18 to 60 years having inguinal hernia admitted in Poona Hospital and Research Centre, Pune, between October 2012 and November 2014 for laparoscopic hernia surgery and ready to participate in this study were included. All of them underwent laparoscopic repair of hernia by total extra peritoneal (TEP) method following sample surgical protocol in all of them except for method of mesh fixation. Mean time calculated from insertion of the first trocar to beginning of skin suturing was 54.9 min in tacker group and 50.3 min in fibrin glue group with no statistically significant difference between the two. The incidence of urinary retention was significantly higher in tacker (34 %) as compared to fibrin glue (12 %) group. Incidence of hematoma was significantly higher in tacker group in 15-day follow-up, but there was no significant difference in hematoma formation at hernial sites in both groups after 15 days of follow-up. The incidence of neuralgia was significantly higher in the tacker group (24 %) compared with the fibrin glue group (2 %). Significantly, more number of people in the fibrin glue group 68 and 90 %, respectively, returned to work during 15 and 30 days follow-up as compared to the tacker group 46 and 64 %. Fibrin glue can be considered as an alternative to tacker for mesh fixation.

Introduction Laparoscopic Nissen operation with mesh reinforcement remains being the most popular operation for large hiatal hernia repair. Complications related to mesh placement have been widely described. Cardiac complications are rare, but have a fatal outcome if they are misdiagnosed. Presentation of cases We sought to outline our institutional experience of three patients who developed cardiac complications following a laparoscopic Nissen operation for large hiatal hernia repair. Discussion Laparoscopic hiatoplasty and Nissen fundoplication are safe and effective procedures for the hiatal hernia repair, but they are not exempt from complications. Fixation technique and material used must be taken into account. We have conducted a review of the literature on complications related to these procedures. Conclusion In the differential diagnosis of hemodynamic instability after laparoscopic hiatal hernia repair, cardiac tamponade and other cardiac complications should be considered. PMID:26635954

The occurrence of enteric fistulae after wall repair using a prosthetic mesh is a serious but, fortunately, rare complication. We report the case of a 66-year-old diabetic man who presented with gas gangrene of the abdominal wall due to an intra-abdominal abscess caused by intestinal erosion six years after an incisional hernia repair using a polyester mesh. The aim of this case report is to illustrate the seriousness of enteric fistula after parietal repair using a synthetic material.
Repair of parastomal hernia remains controversial. Open suture repair of the fascial defect or stoma resiting are both associated with high morbidity and unacceptably high recurrence rates and are no longer recommended for routine use. Mesh repair appears to provide the best results. Following the first anectodal reports there are accumulating evidence that laparoscopic mesh repair is feasible and has a promising potential in the management of parastomal hernia. Two laparoscopic techniques have emerged, the use of a mesh with a slit and a central keyhole and a mesh without a slit, the latter often termed as a modified Sugarbaker. Published series, however, are observational and often with a short length of follow-up. Most series suffer from small sample size and controlled trials are lacking. The limited data, therefore, make it difficult to draw conclusions. At present none of the methods of open or laparoscopic mesh repair has proved superior. In spite of this laparoscopic repair has gained increasing acceptance. A polypropylene based mesh with an anti-adhesive layer covering the visceral side seems to be applicable using the keyhole technique with a slit as well as the modified Sugarbaker technique. A PTFE mesh should preferably be used with the modified Sugarbaker technique. If a PTFE mesh is used with the keyhole technique parastomal hernia is likely to recur.

Incisional hernia is the most common postoperative complication, affecting up to 20% of patients after abdominal surgery. Insertion of a synthetic surgical mesh has become the standard of care in ventral hernia repair. However, the implementation of a mesh does not reduce the risk of recurrence and the onset of hernia recurrence is only delayed by 2-3 years. Nowadays, more than 100 surgical meshes are available on the market, with polypropylene the most widely used for ventral hernia repair. Nonetheless, the ideal mesh does not exist yet; it still needs to be developed. Polycaprolactone nanofibers appear to be a suitable material for different kinds of cells, including fibroblasts, chondrocytes, and mesenchymal stem cells. The aim of the study reported here was to develop a functionalized scaffold for ventral hernia regeneration. We prepared a novel composite scaffold based on a polypropylene surgical mesh functionalized with poly-ε-caprolactone (PCL) nanofibers and adhered thrombocytes as a natural source of growth factors. In extensive in vitro tests, we proved the biocompatibility of PCL nanofibers with adhered thrombocytes deposited on a polypropylene mesh. Compared with polypropylene mesh alone, this composite scaffold provided better adhesion, growth, metabolic activity, proliferation, and viability of mouse fibroblasts in all tests and was even better than a polypropylene mesh functionalized with PCL nanofibers. The gradual release of growth factors from biocompatible nanofiber-modified scaffolds seems to be a promising approach in tissue engineering and regenerative medicine.

The purpose of this study was to evaluate the results of a laparoscopic approach to recurrent inguinal hernia repair which dissected the entire inguinal floor and repaired all potential areas of recurrence without producing tension. Both a transabdominal preperitoneal and a totally extraperitoneal laparoscopic approach were utilized. Ninety recurrent hernias were repaired in 81 patients. The patients had 26 indirect, 36 direct, and 26 pantaloon recurrent hernias of which eight had a femoral component. In all but one patient the primary operations were open anterior repairs. The median follow-up was 14 months, ranging from 1 to 28 months. Patients returned to normal activities in an average of 1 week. The only recurrence observed was in the one patient whose primary repair was laparoscopic. When the entire inguinal floor of the recurrent hernia was redissected and buttressed with mesh, early recurrence was eliminated and recovery was shortened.

The aim of this study is to assess the advantages of fibrin glue over Prolene suture in fixation of the mesh in open inguinal hernia repair. Sixty-four cases of inguinal hernia underwent hernia repair by the Lichtenstein method in the department of surgery in PGIMER & Dr. RML Hospital, New Delhi. The patients were randomized prospectively into group A (fibrin glue group) and group B (Prolene suture group). In group A, fibrin glue was used for mesh fixation, and in group B, Prolene suture was used for mesh fixation. The mean age of patients in group A was 44.5 years and that of group B patients was 44.2 years. There was a significant difference in the duration of surgery, with the mean duration in fibrin glue group being 30.6 min and that of the suture group was 43.3 min. The mean visual analogue pain score of postoperative pain at 1, 6, 12, and 24 h was significantly higher in the suture group than in the fibrin glue group (p < 0.001). The mean total dose of analgesia in ampoules of tramadol was significantly less in the fibrin glue group (1.56 ampoules) than that in the suture group (4.125 ampoules) with p = 0.000. At the end of the first month, 25 % of subjects in the suture group presented with mild groin pain (p value = 0.0048). At the end of the second and third month, 22 % (p 68 value = 0.0048) and 12.5 % (p value = 0.1132) of subjects respectively presented with mild groin pain in the suture group. The present study demonstrates that the use of fibrin glue in place of Prolene suture for mesh fixation in open inguinal hernia repair can help decreasing the time required for surgery, reduce the intensity of postoperative pain, shorten the duration of hospital stay, and prevent the incidence of chronic groin pain.

One hundred and fifty large abdominal incisional hernias were treated following a standardized operating technique using metallic mesh (Toilinox) and approximation of the anterior sheath of the rectus abdominis. The average follow-up was four years. Good clinical results without pain were found in more than 95 per cent of the patients. Recurrence occurred in 9.5 per cent of the patients. The complications, wound infection or parietal necrosis, never necessitated removal of the prosthesis. These results justify the use of this technique even when intra-abdominal septic procedure is associated.

Introduction Mesh augmentation seems to reduce recurrences following laparoscopic paraesophageal hernia repair (LPHR). However, there is an uncertain risk of mesh-associated complications. Risk-benefit analysis might solve the dilemma. Materials and Methods A systematic literature search was performed to identify randomized controlled trials (RCTs) and observational clinical studies (OCSs) comparing laparoscopic mesh-augmented hiatoplasty (LMAH) with laparoscopic mesh-free hiatoplasty (LH) with regard to recurrences and complications. Random effects meta-analyses were performed to determine potential benefits of LMAH. All data regarding LMAH were used to estimate risk of mesh-associated complications. Risk-benefit analysis was performed using a Markov Monte Carlo decision-analytic model. Results Meta-analysis of 3 RCTs and 9 OCSs including 915 patients revealed a significantly lower recurrence rate for LMAH compared to LH (pooled proportions, 12.1% vs. 20.5%; odds ratio (OR), 0.55; 95% confidence interval (CI), 0.34 to 0.89; p = 0.04). Complication rates were comparable in both groups (pooled proportions, 15.3% vs. 14.2%; OR, 1.02; 95% CI, 0.63 to 1.65; p = 0.94). The systematic review of LMAH data yielded a mesh-associated complication rate of 1.9% (41/2121; 95% CI, 1.3% to 2.5%) for those series reporting at least one mesh-associated complication. The Markov Monte Carlo decision-analytic model revealed a procedure-related mortality rate of 1.6% for LMAH and 1.8% for LH. Conclusions Mesh application should be considered for LPHR because it reduces recurrences at least in the mid-term. Overall procedure-related complications and mortality seem to not be increased despite of potential mesh-associated complications. PMID:26469286

Recently, the use of prosthetic mesh has revolutionized the repair of ventral hernias. However, the occurrence of infection related with the use of this prosthesis remains an important complication, which may result in occurrence of fistula formation of the skin or intestine, sepsis, or reoccurrence of ventral hernia. This report presents two cases where a pedicled musculocutaneous flap using the tensor fascia lata (pedicled TFL flap) was effective as a treatment for an infectious large abdominal hernia, and reviews the previous literature. Two Japanese men aged 61 and 78 years old underwent a ventral hernia repair using Composix Kugel mesh. They both developed a wound infection with methicillin-resistant Staphylococcus aureus. Conservative therapy was not successful and the defect in the abdominal wall of two patients measured 12 x 21 cm and 7 x 10 cm in length, respectively. Reoperations were performed by removing the infectious mesh and then reconstructing the abdominal wall with the bilateral and left-side pedicled TFL flaps, respectively. No recurrence of the ventral hernia has been recognized for 50 months and 7 months after reoperation, respectively. A review of previous studies showed that no patients treated with a pedicled TFL flap experienced a recurrent hernia. Therefore, the pedicled TFL flap was considered to be effective for infectious large abdominal recurrent hernia.

Objective: The aim of the study was to evaluate biosynthetic absorbable mesh in single-staged contaminated (Centers for Disease Control class II and III) ventral hernia (CVH) repair over 24 months. Background: CVH has an increased risk of postoperative infection. CVH repair with synthetic or biologic meshes has reported chronic biomaterial infections and high hernia recurrence rates. Methods: Patients with a contaminated or clean-contaminated operative field and a hernia defect at least 9 cm2 had a biosynthetic mesh (open, sublay, retrorectus, or intraperitoneal) repair with fascial closure (n = 104). Endpoints included overall Kaplan-Meier estimates for hernia recurrence and postoperative wound infection rates at 24 months, and the EQ-5D and Short Form 12 Health Survey (SF-12). Analyses were conducted on the intent-to-treat population, and health outcome measures evaluated using paired t tests. Results: Patients had a mean age of 58 years, body mass index of 28 kg/m2, 77% had contaminated wounds, and 84% completed 24-months follow-up. Concomitant procedures included fistula takedown (n = 24) or removal of infected previously placed mesh (n = 29). Hernia recurrence rate was 17% (n = 16). At the time of CVH repair, intraperitoneal placement of the biosynthetic mesh significantly increased the risk of recurrences (P ≤ 0.04). Surgical site infections (19/104) led to higher risk of recurrence (P < 0.01). Mean 24-month EQ-5D (index and visual analogue) and SF-12 physical component and mental scores improved from baseline (P < 0.05). Conclusions: In this prospective longitudinal study, biosynthetic absorbable mesh showed efficacy in terms of long-term recurrence and quality of life for CVH repair patients and offers an alternative to biologic and permanent synthetic meshes in these complex situations.

The aim of this study was to obtain information about the mechanical properties of six meshes commonly used for hernia repair (Surgipro(®), Optilene(®), Infinit(®), DynaMesh(®), Ultrapro™ and TIGR(®)) by planar biaxial tests. Stress-stretch behavior and equibiaxial stiffness were evaluated, and the anisotropy was determined by testing. In particular, equibiaxial test (equal simultaneous loading in both directions) and biaxial test (half of the load in one direction following the Laplace law) were selected as a representation of physiologically relevant loads. The majority of the meshes displayed values in the range of 8 and 18 (N/mm) in each direction for equibiaxial stiffness (tangent modulus under equibiaxial load state in both directions), while a few achieved 28 and 50 (N/mm) (Infinit (®) and TIGR (®)). Only the Surgipro (®) mesh exhibited planar isotropy, with similar mechanical properties regardless of the direction of loading, and an anisotropy ratio of 1.18. Optilene (®), DynaMesh (®), Ultrapro (®) and TIGR (®) exhibited moderate anisotropy with ratios of 1.82, 1.84, 2.17 and 1.47, respectively. The Infinit (®) scaffold exhibited very high anisotropy with a ratio of 3.37. These trends in material anisotropic response changed during the physiological state in the human abdominal wall, i.e. T:0.5T test, which the meshes were loaded in one direction with half the load used in the other direction. The Surgipro (®) mesh increased its anisotropic response (Anis[Formula: see text] = 0.478) and the materials that demonstrated moderate and high anisotropic responses during multiaxial testing presented a quasi-isotropic response, especially the Infinit(®) mesh that decreased its anisotropic response from 3.369 to 1.292.

Two types of anterior tension-free hernioplasty, prolene hernia system (PHS) repair and mesh plug technique (MPT), were introduced to Taiwan in 2001. This study compared the short- to mid-term outcomes following primary groin hernia repair with PHS and MPT. From January 2001 to December 2003, 393 patients with 426 primary groin hernias were operated on by a single surgeon using MPT (n=192) and PHS (n=234). Baseline perioperative details and follow-up information were compared. Demographic characteristics of both groups were similar. The laterality, types of anesthesia, postoperative stay, postoperative wound pain scores, wound complications and days to return to activities of daily life were equally distributed between the two groups. However, the distribution of Gilbert types in the PHS group was shifted a little to the right compared with that of the MPT group. PHS repair had longer operative time (34+/-17 vs 25+/-9 minutes, p<0.01). No recurrence was noted in both groups during the follow-up from 5 to 41 months. Chronic non-disabling groin pains were noted in 2.8% (6/218) of patients in the PHS group and 8.9% (14/175) in the MPT group (p=0.01). Our results show that both PHS and MPT repairs can be performed with short operation time, minor wound pain and quick return to activities of daily life without short- to mid-term recurrences, but postoperatively the MPT group had higher incidence of chronic non-disabling groin pain. Although the MPT is less invasive, the additional protective patch in the preperitoneal space of the PHS may provide a further safeguard against recurrences, especially for those patients with attenuated inguinal floor. Long-term follow-up is needed.

Background and Objectives: The purpose of this study was to analyze the surgical technique, postoperative complications, and possible recurrence after laparoscopic ventral hernia repair (LVHR) in comparison with open ventral hernia repair (OVHR), based on the international literature. Database: A Medline search of the current English literature was performed using the terms laparoscopic ventral hernia repair and incisional hernia repair. Conclusions: LVHR is a safe alternative to the open method, with the main advantages being minimal postoperative pain, shorter recovery, and decreased wound and mesh infections. Incidental enterotomy can be avoided by using a meticulous technique and sharp dissection to avoid thermal injury. PMID:26273186

Introduction This is the second report on objective review of 100 patients who underwent composite fundoplication-cardiopexy for repair of giant hiatus hernia (GHH) at a median of 24 months following surgery. Outcomes were objective follow-up by endoscopy and quality of life (QoL) by Gastrointestinal Quality of Life Index (GIQLI), modified Visick scores and dysphagia scores. The initial report for this cohort suggested a low objective recurrence rate (9%) and substantial improvements in QoL indices. Methods The rate of hernia recurrence was assessed with Kaplan–Meier analysis and covariates were analysed with the Cox proportional hazards model. Paired t-tests and related samples Wilcoxon signed-rank tests were used to compare QoL scores. Unpaired data were compared with the independent samples t-test and Mann–Whitney U test. Results Objective review was obtained in 97% of the patients. There were five recurrences of hernias that had a vertical height of >2cm from the diaphragmatic hiatus, with three patients requiring reoperation for severe dysphagia. Small recurrences (<2cm) occurred in 20 patients. The median time to recurrence was 40 months (95% confidence interval: 34–46 months). At two years, recurrence of any size had occurred in 24% of cases. At follow-up review (median: 27 months), the mean GIQLI score was 109 (p=0.279), the median modified Visick score was 2 (p=0.954) and the median dysphagia score was 41 (p=0.623). There was no evidence that the GIQLI score (p=0.089), the modified Visick score (p=0.339) or the dysphagia score (p=0.445) changed significantly after recurrence. Conclusions There was a sustained improvement in overall QoL and reflux scores after GHH repair. QoL scores showed persistent improvement in reflux and overall health, even in the subgroup with recurrence. The majority (80%) of recurrences were small and recurrent herniation did not appear to significantly change QoL. The rates of recurrence and QoL are comparable with those for

BACKGROUND: The aim of our study was to compare chronic groin pain and quality of life (QOL) after laparoscopic lightweight (LW) and heavyweight (HW) mesh repair for groin hernia. MATERIALS AND METHODS: One hundred and forty adult patients with uncomplicated inguinal hernia were randomised into HW mesh group or LW mesh group. Return to activity, chronic groin pain and recurrence rates were assessed. Short form-36 v2 health survey was used for QOL analysis. RESULTS: One hundred and thirty-one completed follow-up of 3 months, 66 in HW mesh group and 65 in LW mesh group. Early post-operative convalescence was better in LW mesh group in terms of early return to walking (P = 0.01) and driving (P = 0.05). The incidence of early post-operative pain, chronic groin pain and QOL and recurrences were comparable. CONCLUSION: Outcomes following laparoscopic inguinal hernia repair using HW and LW mesh are comparable in the short-term as well as long-term. PMID:27073309

Background and Objectives: A Spigelian hernia is a rare type of hernia that occurs through a defect in the anterior abdominal wall adjacent to the linea semilunaris. Estimation of its incidence has been reported as 0.12% of all abdominal wall hernias. Traditionally, the method of repair has been an open approach. Herein, we discuss a series of laparoscopic repairs. Methods: Case series and review of the literature. Cases: Three patients are presented. All were evaluated and taken to surgery initially for a different disease process, and all were incidentally found to have a spigelian hernia. These patients underwent laparoscopic repair of their hernias; 2 were repaired intraperitoneally and one was repaired totally extraperitoneally. Two patients initially underwent a mesh repair, while the third had an attempted primary repair. Conclusions: There is evidence that supports the use of laparoscopy for both diagnosis and repair of spigelian hernias. There are also reports of successful repairs both primarily and with mesh. In our experience with the preceding 3 patients, we found that laparoscopic repair of incidentally discovered spigelian hernias is a viable option, and we also found that implantation of mesh, when possible, resulted in satisfactory results and no recurrence.

Introduction Prosthetic mesh infection constitutes one of the major complications following hernia repair. Antimicrobial, non-antibiotic biomaterials have the potential to reduce bacterial adhesion to the mesh surface and adjacent tissues while avoiding the development of novel antibiotic resistance. This study assesses the efficacy of presoaking reticular polypropylene meshes in chlorhexidine or a chlorhexidine and allicin combination (a natural antibacterial agent) for preventing bacterial infection in a short-time hernia-repair rabbit model. Methods Partial hernia defects (5 x 2 cm) were created on the lateral right side of the abdominal wall of New Zealand White rabbits (n = 21). The defects were inoculated with 0.5 mL of a 106 CFU/mL Staphylococcus aureus ATCC25923 strain and repaired with a DualMesh Plus antimicrobial mesh or a Surgipro mesh presoaked in either chlorhexidine (0.05%) or allicin-chlorhexidine (900 μg/mL-0.05%). Fourteen days post-implant, mesh contraction was measured and tissue specimens were harvested to evaluate bacterial adhesion to the implant surface (via sonication, S. aureus immunolabeling), host-tissue incorporation (via staining, scanning electron microscopy) and macrophage response (via RAM-11 immunolabeling). Results The polypropylene mesh showed improved tissue integration relative to the DualMesh Plus. Both the DualMesh Plus and the chlorhexidine-soaked polypropylene meshes exhibited high bacterial clearance, with the latter material showing lower bacterial yields. The implants from the allicin-chlorhexidine group displayed a neoformed tissue containing differently sized abscesses and living bacteria, as well as a diminished macrophage response. The allicin-chlorhexidine coated implants exhibited the highest contraction. Conclusions The presoaking of reticular polypropylene materials with a low concentration of chlorhexidine provides the mesh with antibacterial activity without disrupting tissue integration. Due to the

Prosthetic mesh for laparoscopic inguinal hernia repair has become popular but the method of its placement is controversial. Mesh placed within the peritoneum may cause adhesion formation and further complications. The aim of this study was to examine the laparoscopic placement of a mesh, comparing intraperitoneal vs extraperitoneal insertion. In a porcine model (n = 15) a polypropylene mesh was placed laparoscopically over the anterior abdominal wall. On the left side the mesh was stapled on the parietal peritoneum. On the right side the peritoneum was incised, an extraperitoneal space was dissected, the mesh was inserted, and the peritoneum was closed over it. The animals were maintained for 2 weeks. At postmortem there were adhesions in two of those placed extraperitoneally and five of those placed intraperitoneally (P = 0.19, Fisher's exact test). The adhesions comprised fibrous peritoneal bands to loops of small intestine. Both methods of laparoscopic mesh placement were associated with a small but significant incidence of adhesion formation.

Mesh bacterial colonization/infection remains a critical issue in complex ventral hernia repair. Despite the recent emergence of biologic meshes, current strategies to prevent and treat mesh infection are largely ineffective, often leading to device failure and subsequent explantation along with the associated costs and effect on patient welfare. Unacceptably high rates of morbidity and hernia recurrence following mesh infection highlight the need for innovation in the area of hernia repair for the complex patient. One recent strategy to address such shortcomings is local antibiosis in the form of polymer coatings applied to the mesh itself. Current literature regarding the use of antibiotic-coated hernia mesh is limited but does illustrate the ability of these devices to inhibit bacterial growth and prevent mesh infection in both in vitro and in vivo studies. Although there is a paucity of literature regarding long-term clinical efficacy, this provides opportunity for further inquiry into a promising new development to combat mesh infective complications.
Abdominal incisional hernia is a common complication after open abdominal operations. Laparoscopic procedures have obvious mini-invasive advantages for surgical treatment of abdominal incisional hernia, especially to cases with big hernia defect. Laparoscopic repair of incisional hernia has routine mode but the actual operations will be various according to the condition of every hernia. Key points of these operations include design of the position of trocars, closure of defects and fixation of meshes. The details of these issues and experiences of perioperative evaluation and treatment will be talked about in this article. PMID:27761446

Laparoscopic repair of inguinal hernia is mini-invasive and has confirmed effects. Femoral hernia could be repaired through the laparoscopic procedures for inguinal hernia. These procedures have clear anatomic view in the operation and preoperatively undiagnosed femoral hernia could be confirmed and treated. Lower recurrence ratio was reported in laparoscopic procedures compared with open procedures for repair of femoral hernia. The technical details of laparoscopic repair of femoral hernia, especially the differences to laparoscopic repair of inguinal hernia are discussed in this article. PMID:27826574

Surgical mesh is being used for healing hernia, pelvic organ prolapse, skull injuries and urinary incontinence. In this research the effect of fabric structure on the mechanical properties of warp knitted surgical meshes in comparison to abdominal fascia has been investigated. For this purpose, warp knitted surgical mesh with five different structures (Tricot, Pin-hole-net, quasi-Sandfly, Sandfly and quasi-Marquissite) were produced using polypropylene monofilament. Thereafter, their mechanical properties such as uniaxial tensile behavior in various directions (wale-wise (90°), course-wise (0°) and diagonal (45°)), bending resistance and crease recovery were analyzed. The meshes demonstrated different elastic modulus in various directions, which can be attributed to the pore shape (pore angle) and underlap angle in the structure of mesh. Except Pin-hole-net mesh, other produced meshes exhibited better level of orthotropy in comparison to abdominal fascia. The most flexible mesh in both wale-wise and course-wise directions was quasi-Sandfly and thereafter quasi-Marquissite. Tricot and Pin-hole-net manifested the highest crease recovery in wale-wise and coursewise directions respectively. The most desirable mesh in terms of porosity was quasi-Marquissite mesh. Overall, the quasi-Marquissite mesh was selected as the most suitable surgical mesh considering all advantages and disadvantages of each produced mesh in this study.

Following the widespread use of mesh repairs, recurrence rates after inguinal hernia surgery have become acceptable and focus has shifted from recurrence to chronic pain. Although pain can be controlled with analgesics, chronic postsurgical pain is a major clinical problem, which can significantly influence the patient's quality of life. The rate of chronic pain after inguinal hernia mesh repair can reach 51.6%. The reasons for posthernioplasty chronic pain are often unclear. It has been linked to nerve injury and nerve entrapment, but there is also association between the rate of chronic pain and the type of mesh used for hernia repair. As there are >160 meshes available in the market, it is difficult to choose a mesh whose usage would result in the best outcome. Different mesh characteristics have been studied, among them weight of mesh has probably gained the most attention. The choice of adequate therapy for chronic groin pain after inguinal hernia repair is controversial. The European Hernia Society recommends that a multidisciplinary approach at a pain clinic should be considered for the treatment of chronic postoperative pain. Although surgical treatment of chronic posthernioplasty pain is limited because of the lack of relevant research data, resection of entrapped nerves, mesh removal in the case of mesh related pain or removal of fixation sutures can be beneficial for the patient with severe pain after inguinal hernia surgery. One drawback of published studies is the lack of consensus over definition of chronic pain, which makes it complicated to compare the results of different studies and to conduct meta-analyses and systematic reviews. Therefore, a uniform definition of chronic pain and its best assessment methods should be developed in order to conduct top quality multicenter randomized trials. Further research to develop meshes with optimal parameters is of vital importance and should be encouraged.

Objective To discuss the difficulties in dealing with infected or exposed ventral hernia mesh, and to illustrate one solution using an autogenous abdominal wall reconstruction technique. Summary Background Data The definitive treatment for any infected prosthetic material in the body is removal and substitution. When ventral hernia mesh becomes exposed or infected, its removal requires a solution to prevent a subsequent hernia or evisceration. Methods Eleven patients with ventral hernia mesh that was exposed, nonincorporated, with chronic drainage, or associated with a spontaneous enterocutaneous fistula were referred by their initial surgeons after failed local wound care for definitive management. The patients were treated with radical en bloc excision of mesh and scarred fascia followed by immediate abdominal wall reconstruction using bilateral sliding rectus abdominis myofascial advancement flaps. Results Four of the 11 patients treated for infected mesh additionally required a bowel resection. Transverse defect size ranged from 8 to 18 cm (average 13 cm). Average procedure duration was 3 hours without bowel repair and 5 hours with bowel repair. Postoperative length of stay was 5 to 7 days without bowel repair and 7 to 9 days with bowel repair. Complications included hernia recurrence in one case and stitch abscesses in two cases. Follow-up ranges from 6 to 54 months (average 24 months). Conclusions Removal of infected mesh and autogenous flap reconstruction is a safe, reliable, and one-step surgical solution to the problem of infected abdominal wall mesh. PMID:12616130
Laparoscopic repair of inguinal hernia is mini-invasive and has confirmed effects. The procedures include intraperitoneal onlay mesh (IPOM) repair, transabdominal preperitoneal (TAPP) repair and total extraperitoneal (TEP) repair. These procedures have totally different anatomic point of view, process and technical key points from open operations. The technical details of these operations are discussed in this article, also the strategies of treatment for some special conditions. PMID:27867954

Between November 1991 and May 1993, 54 recurrent groin hernias were laparoscopically repaired in 50 patients. Forty-eight were men and two were women. Forty-six recurrent hernias were unilateral and four bilateral. Twenty-five were direct, 19 indirect, 10 pantaloon, and two had a femoral component. In only 10 patients was the contralateral side normal. In 27 patients, the other side had been previously repaired, and in 13 they had a new contralateral hernia. A transabdominal preperitoneal technique was used to dissect and repair the entire floor in all patients. A single sheet of polypropylene mesh was used in the repair of the women patients, and a double-buttress technique with the first sheet slitted for the cord was used for the men. Patients were examined every 3 months for the first year and at 6-month intervals thereafter. Follow-up ranged from 1 to 18 months with a mean of 8 months. No patient was lost to follow-up, and no recurrence was observed. Patients returned to normal activity in an average of 1 week. Seroma, which resolved spontaneously, was the most common complication. The overall short-term results suggested that a laparoscopic mesh buttressed repair of recurrent groin hernias is technically feasible and can eliminate early rerecurrence of the hernia so commonly seen after repair of recurrent hernias.

Ventral hernia repair fails frequently despite advanced mesh inserting surgery. A model for dynamic intermittent straining (DIS) of ventral hernia repairs was developed. The influence of phospholipids, position, overlap, fixation and tissue quality of various meshes on the durability of hernia repair was studied. DIS comprises the repetition of submaximal impacts delivered via a hydraulically driven plastic containment. Pig tissues simulate a ventral hernia with a standardized 5cm defect. Commercially available meshes strengthened with tacks, glue and sutures were used to bridge this defect in an underlay (IPOM) or sublay (retromuscular) position starting with a 5cm overlap in all directions. We tested 35 different ways of ventral hernia repair with up to 425 submaximal intermittent dynamic impacts until mesh dislocation occurred 10 times or a maximum of 4000 impacts each were withstood. The likelihood of a failing repair was related to the mesh, the lubricants, the position, the overlap, the fixation and the tissue quality. Most meshes dislocated easily and required fixation. One of the meshes tested was stable without fixation with a 5cm overlap and failed after reducing the overlap. Phospholipids exerted a strong influence on the biomaterial tested. The sublay position was about 10% more durable in comparison to the IPOM position. DIS revealed distinct degrees of stability with primarily stable, intermediate and primarily unstable repairs. Based on the DIS results available, the currently used ventral hernia repair options can be classified. In the future, DIS investigations can improve the durability of hernia repair.

There is a lack of consensus about the surgical management of umbilical hernias. The aim of this study is to analyze the medium-term results of 934 umbilical hernia repairs. In this study, 934 patients with an umbilical hernia underwent surgery between 2004 and 2010, 599 (64.1%) of which were evaluated at least one year after the surgery. Complications, recurrence, and the reoperation rate were analyzed. Complications were observed in 5.7 per cent of the patients. With a mean follow-up time of 35.5 months, recurrence and reoperation rates were 3.8 per cent and 4.7 per cent, respectively. A higher percentage of female patients (60.9 % vs 29 %, P = 0.001) and a longer follow-up time (47.4 vs 35 months, P = 0.037) were observed in patients who developed a recurrence. No significant differences were observed between complications and the reoperation rate in patients who underwent Ventralex(®) preperitoneal mesh reinforcement and suture repair; however, a trend toward a higher recurrence rate was observed in patients with suture repair (6.5 % vs 3.2 %, P = 0.082). Suture repair had lower recurrence and reoperation rates in patients with umbilical hernias less than 1 cm. Suture repair is an appropriate procedure for small umbilical hernias; however, for larger umbilical hernias, mesh reinforcement should be considered.
Inguinal hernia is a very common problem. Surgical repair is the current approach, whereas asymptomatic or minimally symptomatic hernias may be good candidate for watchful waiting. Prophylactic antibiotics can be used in centers with high rate of wound infection. Local anesthesia is a suitable and economic option for open repairs, and should be popularized in day-case setting. Numerous repair methods have been described to date. Mesh repairs are superior to "nonmesh" tissue-suture repairs. Lichtenstein repair and endoscopic/laparoscopic techniques have similar efficacy. Standard polypropylene mesh is still the choice, whereas use of partially absorbable lightweight meshes seems to have some advantages. PMID:22435019

Background In ventral hernia surgery, mesh implants are used to reduce recurrence. Infection after mesh implantation can be a problem and rates around 6–10% have been reported. Bacterial colonization of mesh implants in patients without clinical signs of infection has not been thoroughly investigated. Molecular techniques have proven effective in demonstrating bacterial diversity in various environments and are able to identify bacteria on a gene-specific level. Objective The purpose of this study was to detect bacterial biofilm in mesh implants, analyze its bacterial diversity, and look for possible resemblance with bacterial biofilm from the periodontal pocket. Methods Thirty patients referred to our hospital for recurrence after former ventral hernia mesh repair, were examined for periodontitis in advance of new surgical hernia repair. Oral examination included periapical radiographs, periodontal probing, and subgingival plaque collection. A piece of mesh (1×1 cm) from the abdominal wall was harvested during the new surgical hernia repair and analyzed for bacteria by PCR and 16S rRNA gene sequencing. From patients with positive PCR mesh samples, subgingival plaque samples were analyzed with the same techniques. Results A great variety of taxa were detected in 20 (66.7%) mesh samples, including typical oral commensals and periodontopathogens, enterics, and skin bacteria. Mesh and periodontal bacteria were further analyzed for similarity in 16S rRNA gene sequences. In 17 sequences, the level of resemblance between mesh and subgingival bacterial colonization was 98–100% suggesting, but not proving, a transfer of oral bacteria to the mesh. Conclusion The results show great bacterial diversity on mesh implants from the anterior abdominal wall including oral commensals and periodontopathogens. Mesh can be reached by bacteria in several ways including hematogenous spread from an oral site. However, other sites such as gut and skin may also serve as sources for the

Background: The characteristics of the ideal type of mesh are still being debated. Mesh shrinkage and fixation have been associated with complications. Avoiding shrinkage and fixation would improve hernia recurrence rates and complications. To our knowledge, this is the first study of a device with a self-expanding frame for laparoscopic hernia repair. Methods: Six Rebound Hernia Repair Devices were placed laparoscopically in pigs. This device is a condensed polypropylene, super-thin, lightweight, macro-porous mesh with a self-expanding Nitinol frame. The devices were assessed for adhesions, shrinkage, and histological examination. Laboratory and radiologic evaluations were also performed. Results: The handling properties of the devices facilitated their laparoscopic placement. They were easily identified with simple x-rays. The mesh was firmly integrated within the surrounding tissue. One device was associated with 3 small adhesions. The other 5 HRDs had no adhesions. We noted no shrinkage or folding. All devices preserved their original size and shape. Conclusions: At this evaluation stage, we found that the Rebound Hernia Repair Device may serve for laparoscopic hernia repair and has favorable handling properties. It prevents folding and shrinkage of the mesh. It may eliminate the need for fixation, thus preventing chronic pain. The Nitinol frame also allowed radiologic evaluation for gross movement. Further studies will be needed to evaluate its clinical application. PMID:20529534

Ghana has a high incidence of inguinal hernias and the healthcare system is unable to deliver an adequate repair rate. This results in morbidity and mortality and has a knock-on effect on the local economy. A project has been set up to try and reduce the burden of these hernias by establishing Africa's first Hernia Centre. This is supported by structured visits by European surgeons to the centre. In October 2006, a team of four surgeons, two specialist registrars, one hernia nurse specialist, and three nurses was assembled in order to open the Hernia Centre, which will provide a base for the delivery of hernia services in the West of Ghana. A 2-year teaching programme has been formulated, tailored to the needs of local surgeons and nurses, with the aim of developing an integrated team that will initially deliver up to 50 hernia repairs each month. It is planned that the centre will be supported by structured periodic visits from surgeons and nurses based in Plymouth, the European Hernia Society, and any other volunteers wishing to support the link.

It was analyzed the results of treatment of 23 patients with large paracolostomic hernias. Twenty patients underwent colostomy suturing and hernial ring Onlay-plasty with polypropylene mesh without tension. Onlay-plasty of hernial ring with own tissues and polypropylene mesh and colostomy reconstruction outside of implant were performed in 3 patients. Onlay-alloplasty with polypropylene mesh "PROLENE" is effective method of treatment of postoperative paracolostomic ventral hernias with colostomy closing as well as with its reconstruction outside of implant.

Failure rate in standard groin hernia repair varies from 3 to 10%. Polypropylene mesh implantation based on Lichtenstein "tension free" method in 1986 year reduced the failure rate to less than 1%. From Feb. '95 to Dec.'96, 115 patients were operated on with 127 groin hernias repair. The average age of patients was 58 years 52 direct hernias, 74 indirect hernias and 1 pantaloon hernia have been diagnosed in examined material, 101 primary repairs and 26 repairs of recurrent hernia have been performed. The operations were performed in subarachnoid anaesthesia--66 patients, in general anaesthesia--11 patients in local anaesthesia--38 patients. After having opened the inguinal canal estimated the type of its wall defect. In case of direct hernia the sac usually was invaginated by absorbing suture. In case of indirect hernia sac was cut and peritoneal cavity left opened. The patch made of polypropylene monofilament mesh (size 6 x 8 cm) was sewn with "tension free" method under spermatic funiculus. As a complication 6 patients had haematomas in operating wounds. Four of the patients had wound infections. One of these patients was operated again and the patch was removed. The patients had no recurrence of hernia during the previous 10.6 months of observation. We haven't confirmed recurrence in examined material, yet it was too short time to estimate the efficiency of repair. The proposed way of groin hernia repair is easy and simple in every-day surgery practice.

Background: A new closure technique is introduced, which uses strips of macroporous polypropylene mesh as a suture for closure of abdominal wall defects due to failures of standard sutures and difficulties with planar meshes. Methods: Strips of macroporous polypropylene mesh of 2 cm width were passed through the abdominal wall and tied as simple interrupted sutures. The surgical technique and surgical outcomes are presented. Results: One hundred and seven patients underwent a mesh sutured abdominal wall closure. Seventy-six patients had preoperative hernias, and the mean hernia width by CT scan for those with scans was 9.1 cm. Forty-nine surgical fields were clean-contaminated, contaminated, or dirty. Five patients had infections within the first 30 days. Only one knot was removed as an office procedure. Mean follow-up at 234 days revealed 4 recurrent hernias. Conclusions: Mesh sutured repairs reliably appose tissue under tension using concepts of force distribution and resistance to suture pull-through. The technique reduces the amount of foreign material required in comparison to sheet meshes, and avoids the shortcomings of monofilament sutures. Mesh sutured closures seem to be tolerant of bacterial contamination with low hernia recurrence rates and have replaced our routine use of mesh sheets and bioprosthetic grafts. PMID:27757361

OBJECTIVE: Surgery for abdominal wall hernias is a common procedure in general surgery practice. The main causes of delay for the operation are comorbid problems and patient unwillingness, which eventually, means that some patients are admitted to emergency clinics with strangulated hernias. In this report, patients who admitted to the emergency department with strangulated adominal wall hernias are presented together with their clinical management. METHODS: Patients who admitted to our clinic between January 2009 and November 2011 and underwent emergency operation were included in the study retrospectively. Demographic characteristics, hernia type, length of hospital stay, surgical treatment and complications were assessed. RESULTS: A total 81 patients (37 female, 44 male) with a mean age of 52.1±17.64 years were included in the study. Inguinal, femoral, umbilical and incisional hernias were detected in 40, 26, 9 and 6 patients respectively. Polypropylene mesh was used in 75 patients for repair. Primary repair without mesh was used in six patients. Small bowel (n=10; 12.34%), omentum (n=19; 23.45%), appendix (n=1; 1.2%) and Meckel’s diverticulum (n=1; 1.2%) were resected. Median length of hospital stay was 2 (1–7) days. Surgical site infection was detected in five (6.2%) patients. No significant difference was detected for length of hospital stay and surgical site infection in patients who had mesh repair (p=0.232 and 0.326 respectively). CONCLUSION: The need for bowel resection is common in strangulated abdominal wall hernias which undergo emergency operation. In the present study, an increase of morbidity was seen in patients who underwent bowel resection. No morbidity was detected related to the usage of prosthetic materials in repair of hernias. Hence, we believe that prosthetic materials can be used safely in emergency cases. PMID:28058336

This study quantitatively assessed polypropylene (PP) hernia mesh degradation and its correlation with patient factors including body mass index, tobacco use, and diabetes status with the goal of improving hernia repair outcomes through patient-matched mesh. Thirty PP hernia mesh explants were subjected to a tissue removal process followed by assessment of their in vivo degradation using Fourier transform infrared, differential scanning calorimetry, and thermogravimetric analysis analyses. Results were then analyzed with respect to patient factors (body mass index, tobacco use, and diabetes status) to determine their influence on in vivo hernia mesh oxidation and degradation. Twenty of the explants show significant surface oxidation. Tobacco use exhibits a positive correlation with modulated differential scanning calorimetry melt temperature and exhibits significantly lower TGA decomposition temperatures than non-/past users. Chemical and thermal characterization of the explanted meshes indicate measurable degradation while in vivo regardless of the patient population; however, tobacco use is correlated with less oxidation and degradation of the polymeric mesh possibly due to a reduced inflammatory response.

One surgeon repaired 72 inguinal hernias in 61 patients by a transabdominal preperitoneal laparoscopic placement of prosthetic mesh. There were 58 male and 3 female patients; the mean age was 47.9 years. Thirty-six unilateral inguinal hernias (either direct or indirect), 11 bilateral inguinal hernias, 12 recurrent inguinal hernias, and 2 unilateral pantaloon inguinal hernias were repaired. There were no operative mortalities. The mean follow-up was 21 months, with a range of 6 to 42 months. Ten hernia recurrences (13.8%) were documented 3 to 24 months postoperatively (mean, 12 months). There were six direct hernia recurrences, two indirect hernia recurrences, and two recurrences of recurrent hernia repairs. Thirteen patients (21.3%) experienced morbidity: seromas in eight, a hematoma in one, an ileus in one, hematuria in one, and neuropathy in two. In our opinion, the significant morbidity and early recurrence rate of a laparoscopic inguinal hernia repair are unacceptable. Enthusiasm for laparoscopic technique to repair inguinal hernias is not justified if similar morbidity and recurrence rates are documented within the surgical community.

Hernia diseases are among the most common and diffuse causes of surgical interventions. Unfortunately, still nowadays there are different phenomena which can cause the hernioplasty failure, for instance post-operative prostheses displacements and proliferation of bacteria in the surgical site. In order to limit these problems, commercial polypropylene (PP) and polypropylene/Teflon (PP/PTFE) bi-material meshes were surface functionalised to confer adhesive properties (and therefore reduce undesired displacements) using polyacrylic acid synthesized by plasma polymerisation (PPAA). A broad physico-chemical and morphological characterisation was carried out and adhesion properties were investigated by means of atomic force microscopy (AFM) used in force/distance (F/D) mode. Once biomedical devices surface was functionalised by PPAA coating, metallic silver nanoparticles (AgNPs) with antimicrobial properties were synthesised and loaded onto the polymeric prostheses. The effect of the PPAA, containing carboxylic functionalities, adhesive coating towards AgNPs loading capacity was verified by means of X-ray photoelectron spectroscopy (XPS). Preliminary measurement of the Ag loaded amount and release in water were also investigated via inductively coupled plasma atomic emission spectroscopy (ICP-AES). Promising results were obtained for the functionalised biomaterials, encouraging future in vitro and in vivo tests.

The strength conferred to a mesh by fixing it with laparoscopic staples and the effects of tissue incorporation have never been quantified. Eighteen dogs were divided into three groups sacrificed at 2 days (5 dogs), 2 weeks (6 dogs), and 2 months (7 dogs). One 3.5- by 5-cm piece of abdominal wall was removed from each side through a median laparotomy, leaving the skin intact. A polypropylene mesh (5 by 7 cm) was fixed over one defect with four Endopath EMS staples (Ethicon Endo-surgery) and over the other with 16 EMS staples. At sacrifice, bursting strength (BS) was measured with an Instron tester and specimens were studied histologically. One-way analysis of variance and the Newmann-Keuls multiple-comparison test were used. BS tests showed that for each period studied, the strength of the repair performed with 16 staples was significantly higher than that obtained when four staples were applied. They also showed that tensile strength increased significantly in both groups as time elapsed. Light microscopy supported the conclusion that the initial strength of the repair was related to the number of clips and was significantly increased by cellular infiltration at 2 weeks and significantly more by collagen deposition at 2 months. At 2 months, BS was significantly higher in the 16-staples group, suggesting that initial fixation still plays a significant role.

Some 114 patients (median age 52 years) underwent laparoscopic hernia repair as a day-case procedure. Twenty-one patients had bilateral and 11 recurrent hernias. Some 113 patients underwent transabdominal preperitoneal mesh repair but one required conversion to open operation. Mean operating time was 24 min for unilateral and 38 min for bilateral repair. In an operating session of 3.5 h, up to five patients (mean 4.4) underwent surgery and as many as seven hernias were repaired. More than 10 per cent of patients were found to have a previously undiagnosed hernia on the opposite side. A total of 111 patients were discharged home on the day of surgery. Major complications included one omental bleed and one small bowel obstruction. Seroma was the commonest minor complication and occurred in 7 per cent of patients. More than 35 per cent of patients needed no postoperative analgesia. To date there has been one recurrence (follow-up range 2-18 months).

Background We sought to determine the efficacy of sutures, human fibrin glue and N-butyl-2-cyanoacrylate for mesh fixation in patients undergoing the plug and mesh procedure for groin hernia. Methods A total of 156 patients with 167 inguinal hernias (11 bilateral) underwent a plug and mesh procedure and were randomly assigned to received either sutures (n = 59 hernias), human fibrin glue (n = 52) or N-butyl-2-cyanoacrylate (n = 56) for mesh fixation. Results The overall morbidity rate was 38.98% in the suture group, 9.62% in the fibrin glue group and 10.71% in the N-butyl-2-cyanoacrylate group (suture v. fibrin glue, p < 0.001; suture v. N-butyl-2-cyanoacrylate, p < 0.001). There was no significant difference in morbidity between the fibrin glue and N-butyl-2-cyanoacrylate groups. Overall, short-term morbidity was significantly higher in the suture group (27.12%) than in the fibrin glue (9.62%, p = 0.01) or N-butyl-2-cyanoacrylate (8.93%, p = 0.004) groups, but there was no significant difference between the fibrin glue and N-butyl-2-cyanoacrylate groups. There was no significant difference between the groups in terms of mean postoperative stay (32.6 h in the suture group v. 30.8 h in the fibrin glue group v. 32.0 h in the N-butyl-2-cyanoacrylate group) or mean time to return to work (20.4 d in the suture group v. 20.3 d in the fibrin glue group v. 19.8 d in the N-butyl-2-cyanoacrylate group). Overall, long-term morbidity was significantly higher in the suture group (11.86%) than in the fibrin glue (0%, p = 0.001) or N-butyl-2-cyanoacrylate (1.78%, p = 0.03) groups. There was no recurrence in any of the groups. Two cases (3.39%) of chronic groin pain were reported in patients in the suture group. A sensation of extraneous body was reported in 5 (8.47%) patients who received sutures and in 1 (1.78%) patient in the N-butyl-2-cyanoacrylate group; there were no reported cases in the fibrin glue group (suture v. fibrin glue, p = 0.01; suture v. N-butyl-2-cyanoacrylate

Background and Objectives: Laparoscopic inguinal hernia repair has become increasingly popular as an alternative to open surgery. The purpose of this study was to evaluate the safety and effectiveness of the laparoscopic total extraperitoneal procedure with the use of staple fixation and polypropylene mesh. Methods: A retrospective chart review examined outcomes of 1240 laparoscopic hernia operations in 783 patients, focusing on intraoperative and early postoperative complications, pain, and time until return to work and normal physical activities. Results: There were no intraoperative complications in this series; 106 patients experienced early postoperative complications across 8 evaluated categories: urinary retention (4.1%), seroma (3.0%), testicular/hemiscrotal swelling (1.9%), testicular atrophy (0%), hydrocele (0.6%), mesh infection (0.1%), and neurological symptoms (transient, 1.0%; persistent, 0.2%). Patients used an average of 5.6 Percocet pills after the procedure, and mean times until return to work and normal activities, including their routine exercise regimen, were 3.0 and 3.8 days, respectively. Conclusion: Complication rates and convalescence times were considered equivalent or superior to those found in other studies assessing both laparoscopic and open techniques. The usage of multiple Endostaples did not result in increased neurologic complications in the early postoperative period when compared with findings in the literature. In the hands of an experienced surgeon, total extraperitoneal repair is a safe, effective alternative to open inguinal hernia repair. PMID:27493471

Parastomal hernia is one of the most common long-term complications after abdominal ostomy. Surgical treatment for parastomal hernia is the only cure but a fairly difficult field because of the problems of infection, effects, complications and recurrence. Laparoscopic repair operations are good choices for Parastomal hernia because of their mini-invasive nature and confirmed effects. There are several major laparoscopic procedures for parastomal hernioplasty. The indications, technical details and complications of them will be introduced and discussed in this article.

Sliding inguinal hernias are usually direct inguinal hernias containing various abdominal viscera. The incidence of bladder forming a part of an inguinal hernia, called as “scrotal cystocele,” is 1–4%. The risk of bladder injury is as high as 12% when repairing this type of hernia. This case report emphasizes this aspect in a 65-year-old man who presented with urinary leak through the scrotal wound following right inguinal hernia repair. PMID:26941501

Incisional and inguinal hernia repair are among the most common procedures of general surgery. Mesh fixation by means of staples or sutures may lead to severe complications. The use of fibrin sealant (FS) has been suggested as alternative, but data on biocompatibility and adhesive strength of FS in combination with macroporous meshes is limited. Ventral hernia (n = 8 per group) was treated in rats in onlay technique with two types of meshes, fibrin sealed or stapled. TI-Mesh (TMxl) extralight and VYPROII (VPII) were tested 17 days post op. No failure in mechanical tests (tensile and burst strength) occurred in sealed or stapled meshes. Histology revealed equally good tissue integration and neovascularization in all groups. Fibrin sealant yields excellent fixation in experimental hernia repair. This rat model is suitable for testing meshes and fixation techniques.

Background Recurrences have been a significant problem following hernia repair. Prosthetic materials have been increasingly used in hernia repair to prevent recurrences. Their use has been associated with several advantages, such as less postoperative pain, rapid recovery, low recurrence rates. Methods In this retrospective study, 540 tension-free inguinal hernia repairs were performed between August 1994 and December 1999 in 510 patients, using a polypropylene mesh (Lichtenstein technique). The main outcome measure was early and late morbidity and especially recurrence. Results Inguinal hernia was indirect in 55 % of cases (297 patients), direct in 30 % (162 patients) and of the pantaloon (mixed) type in 15 % (81 patients). Mean patient age was 53.7 years (range, 18 – 85). Follow-up was completed in 407 patients (80 %) by clinical examination or phone call. The median follow-up period was 3.8 years (range, 1 – 6 years). Seroma and hematoma formation requiring drainage was observed in 6 and 2 patients, respectively, while transient testicular swelling occurred in 5 patients. We have not observed acute infection or abscess formation related to the presence of the foreign body (mesh). In two patients, however, a delayed rejection of the mesh occurred 10 months and 4 years following surgery. There was one recurrence of the hernia (in one of these patients with late mesh rejection) (recurrence rate = 0.2 %). Postoperative neuralgia was observed in 5 patients (1 %). Conclusion Lichtenstein tension-free mesh inguinal hernia repair is a simple, safe, comfortable, effective method, with extremely low early and late morbidity and remarkably low recurrence rate and therefore it is our preferred method for hernia repair since 1994.

Sportman's hernia: (Athletic pubalgia) is an uncommon and poorly understood condition afflicting athletic individuals. Sufferers complain of chronic groin pain and often present diagnostic dilemmas to physicians and physiotherapists. We present a series of cases illustrating the varying presentations of sportman's hernia and diagnostic approaches that can be utilized to exclude common differentials. We also describe laparoscopic mesh repair as an effective treatment option for this condition.

Spigelian hernia is a rare partial abdominal wall defect. The frequent lack of physical findings along with vague associated abdominal complaints makes the diagnosis elusive. A retrospective review of Mayo Clinic patients was performed to find all patients who had undergone surgical repair of a Spigelian hernia from 1976 to 1997. Patients were scrutinized for presentation, work-up, therapy, and outcome. The goal of this study was to obtain long-term outcome. The study was set in a tertiary referral center. There were 76 patients in whom 81 Spigelian hernias were repaired. Symptoms most commonly included an intermittent mass (n = 29), pain (n = 20), pain with a mass (n = 22), and bowel obstruction (n = 5). Five patients were asymptomatic. Preoperative imaging was performed in 21 patients and correctly diagnosed the hernia in 15. Spigelian hernias were repaired by primary suture closure (n = 75), mesh (n = 5), and laparoscopic (n = 1) techniques. Eight patients (10%) required emergent operations. Thirteen hernias (17%) were found to be incarcerated at the time of the operation. Overall mean follow-up for the 76 patients was 8 years, with three hernia recurrences identified. Spigelian hernia is rare and requires a high index of suspicion given the lack of consistent symptoms and signs. An astute physician may couple a proper history and physical examination with preoperative imaging to secure the diagnosis. Mesh and laparoscopic repairs are viable alternatives to the durable results of standard primary closure. Given the high rate of incarceration/strangulation, the diagnosis of Spigelian hernia is an indication for surgical repair.
Background and Objectives: Hiatal hernia is a common condition often associated with symptomatic gastroesophageal reflux disease (GERD). The objectives of this study were to examine the efficacy and safety of laparoscopic hiatal hernia repair (LHHR) with biologic mesh to reduce and/or alleviate GERD symptoms and associated hiatal hernia recurrence. Methods: We retrospectively reviewed consecutive LHHR procedures with biologic mesh performed by a single surgeon from July 2009 to October 2014. The primary efficacy outcome measures were relief from GERD symptoms, as measured according to the GERD–health-related quality-of-life (GERD-HRQL) scale and hiatal hernia recurrence. A secondary outcome measure was overall safety of the procedure. Results: A total of 221 patients underwent LHHR with biologic mesh during the study period, and pre- and postoperative GERD-HRQL studies were available for 172 of them. At baseline (preoperative), the mean GERD-HRQL score for all procedures was 18.5 ± 14.4. At follow-up (mean, 14.5 ± 11.0 months [range, 2.0–56.0]), the score showed a statistically significant decline to a mean of 4.4 ± 7.5 (P < .0001). To date, 8 patients (3.6%, 8/221) have had a documented anatomic hiatal hernia recurrence. However, a secondary hiatal hernia repair reoperation was necessary in only 1 patient. Most complications were minor (dysphagia, nausea and vomiting). However, there was 1 death caused by a hemorrhage that occurred 1 week after surgery. Conclusions: Laparoscopic hiatal hernia repair using biologic mesh, both with and without a simultaneous bariatric or antireflux procedure, is an efficacious and safe therapeutic option for management of hiatal hernia, prevention of recurrence, and relief of symptomatic GERD.

An asymptomatic patient was admitted as his chest photograph and computed tomography scans showed a giant Morgagni’s hernia (MH). And it was repaired by laparoscopic approach under epidural anesthesia without endotracheal intubation. The hernia content of omentum was repositioned back into the abdominal cavity, and the diaphragmatic defect was repaired with composite mesh. Which indicated that non-intubated laparoscopic mesh repair via epidural anesthesia is reliable and satisfactory for MH. PMID:27621903

INTRODUCTION Standard open anterior inguinal hernia repair is nowadays performed using a soft mesh to prevent recurrence and to minimalize postoperative chronic pain. To further reduce postoperative chronic pain, the use of a preperitoneal placed mesh has been suggested. In extremely large hernias, the lateral side of the mesh can be insufficient to fully embrace the hernial sac. We describe the use of two preperitoneal placed meshes to repair extremely large hernias. This ‘Butterfly Technique’ has proven to be useful. Hernias were classified according to hernia classification of the European Hernia Society (EHS) during operation. Extremely large indirect hernias were repaired by using two inverted meshes to cover the deep inguinal ring both medial and lateral. Follow up was at least 6 months. VAS pain score was assessed in all patients during follow up. Outcomes of these Butterfly repairs were evaluated. Medical drawings were made to illustrate this technique. A Total of 689 patients underwent anterior hernia repair 2006–2008. PRESENTATION OF CASE Seven male patients (1%) presented with extremely large hernial sacs. All these patients were men. Mean age 69.9 years (range: 63–76), EHS classifications of hernias were all unilateral. Follow up was at least 6 months. Recurrence did not occur after repair. Chronic pain was not reported. Discussion Open preperitoneal hernia repair of extremely large hernias has not been described. The seven patients were trated with this technique uneventfully. No chronic pain occurred. CONCLUSION The Butterfly Technique is an easy and safe alternative in anterior preperitoneal repair of extremely large inguinal hernias. PMID:22288042

Background and Objective: Laparoscopic treatment of incisional hernias can be performed using different types of fixation devices and prosthesis. We present a case series of 19 patients with incisional hernias with a diameter of <6cm, who underwent laparoscopic repair using Hi-tex dual-side mesh, positioned intraperitoneally, fixed to the abdominal wall by fibrin glue (Tissucol). Methods: Nineteen patients with incisional hernias <6cm in diameter were enrolled in this study and treated laparoscopically with Hi-tex and Tissucol. Surgical complications and patient outcomes were assessed with a clinical follow-up. Results: Laparoscopic repair of incisional hernias by using Hi-tex mesh affixed to the parietal wall with fibrin glue was feasible and easy in patients with parietal defects <6cm in diameter. Mean operating time was 30 minutes. Mean hospital stay was 1.5 days. Almost no postoperative pain, major surgical complications, seroma formation, relapses, or prosthesis infection occurred during a mean follow-up of 20 months. Conclusions: In select patients, Hi-tex mesh affixed using fibrin glue allows laparoscopic repair of incisional hernias with very good patient outcomes, especially in terms of postoperative pain and seroma formation.

Tumors presenting in the inguinal hernia sac are considered to be extremely rare, with the more common neoplasms metastasizing from the gastrointestinal tract, ovary and prostate. We report the case of Mantle cell lymphoma identified in the inguinal hernia sac following hernia repair. While the hernia sac appeared normal to the surgeon, evaluation by the pathologist showed subtle gross irregularities, with subsequent histologic and immunochemical diagnosis of Mantle cell lymphoma. Twelve previous cases of a lymphoma diagnosed during hernia repair have been described in the English literature. This is the first report of Mantle cell lymphoma found in the hernia sac. This case illustrates the value of routine microscopic evaluation of hernia sacs found from inguinal/femoral herniorrhaphies, as it may be the primary presentation of an asymptomatic metastatic lymphoma. Additionally, it underscores the importance of the surgeon's role in screening hernia sacs if the practice of submitting only macroscopically abnormal specimens for microscopic evaluation is adopted.

Objective: Laparoscopic paraesophageal hernia repair (LPEHR) is associated with a high recurrence rate. Repair with synthetic mesh lowers recurrence but can cause dysphagia and visceral erosions. This trial was designed to study the value of a biologic prosthesis, small intestinal submucosa (SIS), in LPEHR. Methods: Patients undergoing LPEHR (n = 108) at 4 institutions were randomized to primary repair −1° (n = 57) or primary repair buttressed with SIS (n = 51) using a standardized technique. The primary outcome measure was evidence of recurrent hernia (≥2 cm) on UGI, read by a study radiologist blinded to the randomization status, 6 months after operation. Results: At 6 months, 99 (93%) patients completed clinical symptomatic follow-up and 95 (90%) patients had an UGI. The groups had similar clinical presentations (symptom profile, quality of life, type and size of hernia, esophageal length, and BMI). Operative times (SIS 202 minutes vs. 1° 183 minutes, P = 0.15) and perioperative complications did not differ. There were no operations for recurrent hernia nor mesh-related complications. At 6 months, 4 patients (9%) developed a recurrent hernia >2 cm in the SIS group and 12 patients (24%) in the 1° group (P = 0.04). Both groups experienced a significant reduction in all measured symptoms (heartburn, regurgitation, dysphagia, chest pain, early satiety, and postprandial pain) and improved QOL (SF-36) after operation. There was no difference between groups in either pre or postoperative symptom severity. Patients with a recurrent hernia had more chest pain (2.7 vs. 1.0, P = 0.03) and early satiety (2.8 vs. 1.3, P = 0.02) and worse physical functioning (63 vs. 72, P = 0.03 per SF-36). Conclusions: Adding a biologic prosthesis during LPEHR reduces the likelihood of recurrence at 6 months, without mesh-related complications or side effects. PMID:16998356

More than 1 million inguinal hernia repairs are performed in Europe and the US annually. Although antibiotic prophylaxis is not required in clean, elective procedures, the routine use of implants (90% of inguinal hernia repairs are performed with mesh) makes the topic controversial. The European Hernia Society does not recommend routine antibiotic prophylaxis for elective inguinal hernia repairs. However, the latest randomized controlled trial, published by Mazaki et al., indicates that the use of prophylaxis is effective for the prevention of surgical site infection. Unnecessary prophylaxis contributes to the development of bacterial resistance and significantly increases healthcare costs. This review documents clinical trials on inguinal hernia repairs with mesh and summarizes the current knowledge. It also tries to solve certain problems, namely: what constitutes a real risk factor, late-onset infection, and how the “surgical environment” impacts on the need to use antibiotic prophylaxis.

Background, Aims, and Objectives. Congenital diaphragmatic hernia typically presents in childhood but in adults is extremely rare entity. Surgery is indicated for symptomatic and asymptomatic patients who are fit for surgery. It can be done by laparotomy, thoracotomy, thoracoscopy, or laparoscopy. With the advent of minimal access techniques, the open surgical repair for this hernia has decreased and results are comparable with early recovery and less hospital stay. The aim of this study is to establish that laparoscopic repair of congenital diaphragmatic hernia is a safe and effective modality of surgical treatment. Materials and Methods. A retrospective study of laparoscopic diaphragmatic hernia repair done during May 2011 to Oct 2014. Total n = 13 (M/F: 11/2) cases of confirmed diaphragmatic hernia on CT scan, 4 cases Bochdalek hernia (BH), 8 cases of left eventration of the diaphragm (ED), and one case of right-sided eventration of the diaphragm (ED) were included in the study. Largest defect found on the left side was 15 × 6 cm and on the right side it was 15 × 8 cm. Stomach, small intestine, transverse colon, and omentum were contents in the hernial sac. The contents were reduced with harmonic scalpel and thin sacs were usually excised. The eventration was plicated and hernial orifices were repaired with interrupted horizontal mattress sutures buttressed by Teflon pieces. A composite mesh was fixed with nonabsorbable tackers. All patients had good postoperative recovery and went home early with normal follow-up and were followed up for 2 years. Conclusion. The laparoscopic repair is a safe and effective modality of surgical treatment for congenital diaphragmatic hernia in experienced hands. PMID:28074156

Background The role of laparoscopic repair of ventral hernias remains incompletely defined. We hypothesize that laparoscopy, compared to open repair with mesh, decreases surgical site infection (SSI) for all ventral hernia types. Methods MEDLINE, EMBASE, and Cochrane databases were reviewed to identify studies evaluating outcomes of laparoscopic versus open repair with mesh of ventral hernias and divided into groups (primary or incisional). Studies with high risk of bias were excluded. Primary outcomes of interest were recurrence and SSI. Fixed effects model was used unless significant heterogeneity, assessed with the Higgins I-square (I2), was encountered. Results There were five and fifteen studies for primary and incisional cohorts. No difference was seen in recurrence between laparoscopic and open repair in the two hernia groups. SSI was more common with open repair in both hernia groups: primary (OR 4.17, 95%CI [2.03–8.55]) and incisional (OR 5.16, 95%CI [2.79–9.57]). Conclusions Laparoscopic repair, compared to open repair with mesh, decreases rates of SSI in all types of ventral hernias with no difference in recurrence. This data suggests that laparoscopic approach may be the treatment of choice for all types of ventral hernias. PMID:25294541

The plug-and-patch technique is frequently used for the open repair of inguinal hernias; however, serious complications may arise on rare occasions. We present the case of a 69-year-old patient who presented with a colocutaneous fistula with the sigmoid colon 9 years after the repair of a left sliding inguinal hernia with the plug-and-patch technique. The patient underwent sigmoidectomy and excision of the fistulous track. He was discharged on postoperative day 5 and had an uneventful recovery. Although such complications are reported rarely, the surgeon must be aware of them when deciding upon the method of hernia repair. PMID:27738544

Chronic groin pain (Inguinodynia) following inguinal hernia repair is a significant, though under-reported problem. Mild pain lasting for a few days is common following mesh inguinal hernia repair. However, moderate to severe pain persisting more than 3 mo after inguinal herniorrhaphy should be considered as pathological. The major reasons for chronic groin pain have been identified as neuropathic cause due to inguinal nerve(s) damage or non-neuropathic cause due to mesh or other related factors. The symptom complex of chronic groin pain varies from a dull ache to sharp shooting pain along the distribution of inguinal nerves. Thorough history and meticulous clinical examination should be performed to identify the exact cause of chronic groin pain, as there is no single test to confirm the aetiology behind the pain or to point out the exact nerve involved. Various studies have been performed to look at the difference in chronic groin pain rates with the use of mesh vs non-mesh repair, use of heavyweight vs lightweight mesh and mesh fixation with sutures vs. glue. Though there is no convincing evidence favouring one over the other, lightweight meshes are generally preferred because of their lesser foreign body reaction and better tolerance by the patients. Identification of all three nerves has been shown to be an important factor in reducing chronic groin pain, though there are no well conducted randomised studies to recommend the benefits of nerve excision vs preservation. Both non-surgical and surgical options have been tried for chronic groin pain, with their consequent risks of analgesic side-effects, recurrent pain, recurrent hernia and significant sensory loss. By far the best treatment for chronic groin pain is to avoid bestowing this on the patient by careful intra-operative handling of inguinal structures and better patient counselling pre- and post-herniorraphy.
Background. Parastomal hernia is a common complication after stoma formation, especially in permanent colostomy. The present meta-analysis aimed to evaluate the effectiveness of prophylactic mesh application during permanent colostomy for preventing parastomal hernia. Methods. Randomized controlled trials comparing outcomes in patients who underwent colostomy with or without prophylactic mesh application were identified from PubMed, EMBASE, Science Citation Index, and the Cochrane Libraries. Results. This meta-analysis included 8 randomized controlled trials with 522 participants. Our pooled results showed that prophylactic mesh application (mesh group) reduced the incidence of clinically detected parastomal hernia (risk ratio [RR]: 0.22; 95% confidence interval [CI]: 0.13–0.38; P < 0.00001), radiologically detected parastomal hernia (RR: 0.62; 95% CI: 0.47–0.82; P = 0.0008), and surgical repair for herniation (RR: 0.34; 95% CI: 0.14–0.83; P = 0.02) when compared with conventional permanent colostomy formation (control group). The incidence of complications, including wound infection, peristomal infection, mesh infection, stomal necrosis and stenosis, stoma site pain, and fistula, was not higher in the mesh group than in the control group. Conclusions. Our meta-analysis demonstrated that prophylactic mesh application at the time of primary colostomy formation is a promising method for the prevention of parastomal herniation.

Introduction Inguinal hernias have been treated traditionally with open methods of herniorrhaphy or hernioplasty. But the trends have changed in the last decade with the introduction of minimal access surgery. Methods This study was a prospective descriptive study in patients presenting to Surgery Department of B. P. Koirala Institute of Health Sciences, Dharan, Nepal with reducible inguinal hernias from January 2011 to June 2012. All patients >18 years of age presenting with inguinal hernias were given the choice of laparoscopic repair or open repair. Those who opted for laparoscopic repair were included in the study. Results There were 50 patients, age ranged from 18 to 71 years with 34 being median age at presentation. In 41 patients, totally extraperitoneal repair was attempted. Of these, 2 (4%) repairs were converted to transabdominal repair and 2 to open mesh repair (4%). In 9 patients, transabdominal repair was done. The median total hospital stay was 4 days (range 3-32 days), the mean postoperative stay was 3.38±3.14 days (range 2-23 days), average time taken for full ambulation postoperatively was 2.05±1.39 days (range 1-10 days), and median time taken to return for normal activity was 5 days (range 2-50 days). One patient developed recurrence (2%). None of the patients who had laparoscopic repair completed complained of neuralgias in the follow-up. Conclusion Laparoscopic repair of inguinal hernias could be contemplated safely both via totally extra peritoneal as well as transperitoneal route even in our setup of a developing country with modifications.

Parastomal hernia is a prevalent problem and treatment can pose difficulties due to significant rates of recurrence and morbidities of the repair. The current standard of care is to perform parastomal hernia repair with mesh whenever possible. There exist multiple options for mesh reinforcement (biologic and synthetic) as well as surgical techniques, to include type of repair (keyhole and Sugarbaker) and position of mesh placement (onlay, sublay, or intraperitoneal). The sublay and intraperitoneal positions have been shown to be superior with a lower incidence of recurrence. This procedure may be performed open or laparoscopically, both having similar recurrence and morbidity results. Prophylactic mesh placement at the time of stoma formation has been shown to significantly decrease the rates of parastomal hernia formation. PMID:25435825

Complications associated with implantation of polymeric hernia meshes remain a difficult surgical challenge. We report here on our work, developing for the first time, an injectable viscous material that can be converted to a solid and elastic implant in vivo, thus successfully closing herniated tissue. In this study, long-chain fatty acids were used for the preparation of telechelic macromonomers end-capped with methacrylic functionalities to provide UV curable systems possessing high biocompatibility, good mechanical strength and flexibility. Two different systems, comprising urethane and ester bonds, were synthesized from non-toxic raw materials and then subjected to UV curing after injection of viscous material into the cavity at the abdominal wall during hernioplasty in a rabbit hernia model. No additional fixation or sutures were required. The control group of animals was treated with commercially available polypropylene hernia mesh. The observation period lasted for 28 days. We show here that artificially fabricated defect was healed and no reherniation was observed in the case of the fatty acid derived materials. Importantly, the number of inflammatory cells found in the surrounding tissue was comparable to these found around the standard polypropylene mesh. No inflammatory cells were detected in connective tissues and no sign of necrosis has been observed. Collectively, our results demonstrated that new injectable and photocurable systems can be used for minimally invasive surgical protocols in repair of small hernia defects.

Hernias remain one of the most common ailments to affect men and women worldwide. Surgical mesh materials were first used to reinforce hernia defects during surgery in the late 1950s (Laker, n.d.). Today, there are well over 50 prosthetic meshes available for hernia repair (Brown and Finch, 2010; Bryan et al., 2014; Hope and El-hayek, 2014). With the multitude of available options, surgeons are faced with the challenging task of optimizing mesh selection for each patient. If the mechanics of the mesh are not compatible with the surrounding tissue, mismatch can occur, which can lead to complications such as mesh failure and/or hernia recurrence. Unfortunately, many aspects of synthetic mesh mechanics remain poorly described. Therefore, the purpose of this study was to provide a more complete mechanical analysis of a variety of commercially available prosthetic meshes for hernia repair, including evaluation of meshes in a variety of orientations. Twenty different meshes were subjected to biaxial tensile tests at both 90° and 45° orientations, and results were analyzed for relative strength, strain behavior, and anisotropy. Peak tension and strain values varied dramatically across all mesh types for all directions, ranging between 4.08 and 25.74N/cm and -5% to 10% strain. Anisotropy ratios for the evaluated meshes ranged from 0.33 to 1.89, demonstrating a wide range in relative direction-dependence of mesh mechanics. While further study of prosthetic meshes and better characterization of properties of the human abdominal wall are needed, results of this study provide valuable data that may aid clinicians in optimizing mesh selection for specific patients and repair conditions.

Abdominal wall hernias are a common problem in the general population. A Western estimate reveals that the lifetime risk of developing a hernia is about 2%.1–3 As a result, hernia repairs likely comprise the most frequent general surgery operations. More than 20 million hernias are estimated to be repaired every year around the world.4 Numerous repair techniques have been described to date however tension-free mesh repairs are widely used today because of their low hernia recurrence rates. Nevertheless, there are some ongoing debates regarding the ideal approach (open or laparoscopic),5,6 the ideal anesthesia (general, local, or regional),7,8 and the ideal mesh (standard polypropylene or newer meshes).9,10 PMID:25216417

We present a case of a combination of primary and secondary diaphragmatic hernia in a 63-year male patient. For progressive dyspnea and palpitations caused by a large and symptomatic Morgagni hernia resulting in a right-sided enterothorax, an open tension-free mesh repair was performed. The postoperative course was complicated by a secondary hepatothorax through a spontaneous rupture of the right diaphragm. Primary mesh repair of the Morgagni hernia, however, proved to be sufficient. This recurrent herniation might be a consequence of (1) preexisting atrophy of the right diaphragm caused by disposition and/or long-term diaphragmatic dysfunction due to the large hernia, combined with (2) further thinning out of the diaphragm by intraoperative hernia sac resection, and (3) postoperative increase of intra-abdominal pressure.

Introduction The available classical approaches for Groin hernia are multiple. The change of approach with change of incision is needed with these approaches when the bowel is gangrenous. Aim To evaluate the efficacy and safety of a new approach for all strangulated groin hernias (inguinal, femoral and obturator), in terms of change of approach/complications. Materials and Methods It was conducted in surgical unit-2 of MGM Hospital, Kakatiya Medical College Warangal, Telangana State, India, from Nov 2000 to Oct 2010. Total 52 patients operated with classical approach were compared with 52 patients operated present new approach. All the cases (52+52) were with gangrenous bowel which required resection and end to end anastomosis of bowel. All the cases (52+52) were managed with mesh repair and the results were analysed. Results In classical approach: Three cases required laparotomy (5.7%). Twelve cases required change of approach with change of incision (23%). Eight cases developed wound infection after mesh repair (15%). Four cases required removal of mesh (7.6%). Two Cases developed recurrence (3.8%). In present new approach: No laparotomy (0%), no change of incision (0%), no removal of mesh (0%) and no recurrence(0%). Only 2 cases (3.8%) developed wound infection at lateral part of incision ie. p<0.05. Conclusion This new approach for all - gives a best approach for strangulated groin hernias as it is easy to follow. It obviates the change of incision and need for a laparotomy. It further retains normal anatomy, prevents contamination of the inguinal canal and permits a mesh repair leading to decreasing the chances of recurrence. PMID:27190878

Two hundred and forty four patients underwent either simultaneous bilateral inguinal hernia repair (n = 122) or unilateral inguinal hernia (n = 122) repair at a general hospital between January 1971 and December 1981. The two groups of patients were matched for age and sex. Both groups had a similar overall incidence of post-operative complications and in both groups the duration of post-operative stay and duration of operating time were similar. Chest infections developed in 12 patients after bilateral repair and in 3 patients after unilateral repair (P less than 0.02). All patients were assessed prospectively from 4 to 15 years after operation, when no significant difference in the number of recurrent hernias was found. Our results suggest that simultaneous bilateral inguinal herniorrhaphy is economical in terms of both operating time and duration of hospital stay, and that this economy is not bought at a cost of increased short term morbidity or long-term recurrence rate.

About 600,000 hernia repair surgeries are performed each year. The use of laparoscopic minimally invasive techniques has become increasingly popular in these operations. Use of surgical mesh in hernia repair has shown lower recurrence rates compared to other repair methods. However in many procedures, placement of surgical mesh can be challenging and even complicate the procedure, potentially leading to lengthy operating times. Various techniques have been attempted to improve mesh placement, including use of specialized systems to orient the mesh into a specific shape, with limited success and acceptance. In this work, a programmed novel Shape Memory Polymer (SMP) was integrated into commercially available polyester surgical meshes to add automatic unrolling and tissue conforming functionalities, while preserving the intrinsic structural properties of the original surgical mesh. Tensile testing and Dynamic Mechanical Analysis was performed on four different SMP formulas to identify appropriate mechanical properties for surgical mesh integration. In vitro testing involved monitoring the time required for a modified surgical mesh to deploy in a 37°C water bath. An acute porcine model was used to test the in vivo unrolling of SMP integrated surgical meshes. The SMP-integrated surgical meshes produced an automated, temperature activated, controlled deployment of surgical mesh on the order of several seconds, via laparoscopy in the animal model. A 30 day chronic rat model was used to test initial in vivo subcutaneous biocompatibility. To produce large more clinical relevant sizes of mesh, a mold was developed to facilitate manufacturing of SMP-integrated surgical mesh. The mold is capable of manufacturing mesh up to 361 cm2, which is believed to accommodate the majority of clinical cases. Results indicate surgical mesh modified with SMP is capable of laparoscopic deployment in vivo, activated by body temperature, and possesses the necessary strength and

Introduction Inguinal hernia repairs are routinely performed as outpatient procedures in most patients, whereas a few require admission due to clinical or social peculiarities. Muscular dystrophies are inherited disorders characterized by progressive muscle wasting and weakness. In case of surgery there is no definite recommendation for either general or regional anesthesia. Case report This contribution regards a 48 y. o. male patient diagnosed with Becker Muscular Dystrophy by muscle biopsy 10 years earlier. He had a left-sided sizable inguinoscrotal hernia with repeat episodes of incarceration. An elective mesh repair with suction drainage was accomplished under selective spinal anesthesia. The post-operative course was uneventful. Discussion A few inguinal hernia repairs require admission due to peculiarities such as extensive scrotal hernias requiring suction drainage. Muscular dystrophies are inherited disorders with no cure and no two dystrophy patients are exactly alike, therefore the health issues will be different for each individual. In case of surgery there is no definite recommendation for either general or regional anesthesia. This contribution regards the successful elective mesh repair with suction drainage of a large left-sided inguino-scrotal hernia in a 48 y. o. male patient affected by Becker muscular dystrophy by selective spinal anesthesia obtained by 10 milligrams of hyperbaric bupivacaine. Conclusion Effective mesh repair with suction drainage of large inguinal hernias under spinal anesthesia can be achieved in patients affected by muscular dystrophy. PMID:28098058

Background The surgical approach to paraesophageal hernias (PEH) has changed with the advent of laparoscopic techniques. Variation in both perioperative outcomes and hernia recurrence rates are reported in the literature. We sought to evaluate the short-and intermediate-term outcomes with laparoscopic PEH repair. Methods We performed a retrospective review of patients having laparoscopic repair of PEH between June 1998 and September 2002. We included patients with more than 120 days of follow-up. Results A total of 58 patients with a mean age of 60.4 (standard deviation [SD] 15.0) years had a laparoscopic procedure to repair a primary PEH, as well as adequate follow-up, during the study period. The types of PEH included type II (n = 13), III (n = 44) and IV (n = 1). The most common symptoms were epigastric pain (57%), dysphagia (40%), heartburn (31%) and vomiting (28%). Associated procedures included 56 (96%) Nissen fundoplications and 2 (4%) gastropexies. We closed all crural defects either with or without pledgets, and 2 patients required the use of mesh. There was 1 conversion to open surgery owing to intraoperative bleeding secondary to a consumptive coagulopathy; we observed no other major intraoperative emergencies. Minor or major complications occurred in 15 patients (26%). Late postoperative complications included 1 umbilical hernia. The mean length of stay in hospital was 3.8 (SD 2.5) days. After surgery, 19 patients were completely asymptomatic, and the majority of the remaining patients (83%) described marked symptom improvement. Upper gastrointestinal series performed in symptomatic patients in the postoperative setting identified 5 recurrent paraesophageal hernias (8.6%) and 5 small sliding hernias (9%). Conclusion Laparoscopic repair of PEH is associated with improved long-term symptom relief, low morbidity and acceptable recurrence rates when performed in an experienced centre. PMID:18841230

Most patients who come to a general hospital in a developing country are poor. The most important prohibiting factor for use of polypropylene mesh in hernia repair is its exorbitant cost. Hence, research workers have been on the lookout for an equally effective but economically affordable mesh. Worldwide, surgical repair of inguinal hernia is the most common general surgery procedure performed at the present. Lifetime risk of groin hernia is 15% in males and 5% in females. Most of the patients who visit a general hospital are from either lower middle class or poor socioeconomic strata. The most important prohibiting factor for use of polypropylene mesh in hernia repair for the common man is its exorbitant cost. The aim of this study is to document the feasibility, safety and cost-effectiveness of the use of polyethylene mesh. A single blind, prospective, randomized controlled study, comparing 35 patients of two groups was conducted in a tertiary teaching hospital over a period of 5 years. The patients in both groups underwent inguinal hernioplasty, and were administered similar antibiotics and analgesics. The postoperative course with regard to pain, seroma formation, infection, hospital stay, recurrence and scar quality was evaluated and compared. Statistical analysis was performed with Chi square test. The properties of both meshes were the same with respect to ease of handling, pain score, seroma formation, infection rate, resumption of daily activities, scar quality and mesh rejection. Recurrence rate was zero for both groups. Polyethylene mesh was 2,808 times cheaper than the commercially available polypropylene mesh. This study proved the safety, simplicity, efficacy and cost-effectiveness of polyethylene mesh for inguinal hernia meshplasty, insuring economical, accessible health care for the financially weak section of the population.

ABSTRACT Objective: To evaluate two types of meshless open inguinal repair and to evaluate the recurrence rate. Methods: We operated on sequentially 98 men and 15 women with 144 unilateral or bilateral inguinal hernias between December 1988 and April 2007. The surgeries were performed by two experienced surgeons and divided into two groups: Bassini or McVay reconstructive surgery techniques. Bassini type reinforcements were employed for Nyhus II and IIIB with minor destruction of the posterior wall. Patients with Nyhus type IIIA, type IIIB with major destruction of the fascia transversalis, and type IIIC were subjected to the McVay technique. Results: Seventy-five hernias were corrected using the McVay technique. Only two recurrences (2.67%) were observed in this group. For group Bassini, two recurrences for 69 hernias (2.89%) were observed (p=0.658). Mean age for the recurrent group was 56 years. No differences were observed between the ages of males and females (52 years). Conclusions: Non-mesh repair in inguinal hernia can be safely used if performed by experienced surgeons. PMID:23843059

The advent of mesh devices allowed for tension-free inguinal hernia repairs and a subsequent reduction in the rate of recurrences. In 1993, Rutkow and Robbins introduced the plug-and-patch repair method whereby the hernia defect is filled with a mesh plug. This new procedure led to new technique-specific complications. Here, we report the case of a man who presented with obstructive symptoms and pain at the site of his inguinal hernia repair performed with the Prolene Hernia System((R)) 18 months prior. At laparotomy, he was found to have a small bowel obstruction and perforation due to mesh contact with the small bowel and colon. The literature is reviewed for cases of bowel complications due to mesh plugs. Based on reported complications, three recommendations can be made to avoid or reduce the risk of this complication. First, the pre-peritoneal dissection should be performed carefully with particular attention to identify and repair any tears of the peritoneum. Secondly, the mesh plug should not be placed too deep within the defect. Finally, the plug should be secured to reduce the possibility of mesh migration.

Although mesenterioaxial gastric volvulus is an uncommon entity characterized by rotation at the transverse axis of the stomach, laparoscopic repair procedures have still been controversial. We reported a case of mesenterioaxial intrathoracic gastric volvulus, which was successfully treated with laparoscopic repair of the diaphragmatic hiatal defect using a polytetrafluoroethylene mesh associated with Toupet fundoplication. A 70-year-old Japanese woman was admitted to our hospital because of sudden onset of upper abdominal pain. An upper gastrointestinal series revealed an incarcerated intrathoracic mesenterioaxial volvulus of the distal portion of the stomach and the duodenum. The complete laparoscopic approach was used to repair the volvulus. The laparoscopic procedures involved the repair of the hiatal hernia using polytetrafluoroethylene mesh and Toupet fundoplication. This case highlights the feasibility and effectiveness of the laparoscopic procedure, and laparoscopic repair of the hiatal defect using a polytetrafluoroethylene mesh associated with Toupet fundoplication may be useful for preventing postoperative recurrence of hiatal hernia, volvulus, and gastroesophageal reflux.

Background and Objectives: Mesh fixation during laparoscopic totally extraperitoneal repair is thought to be necessary to prevent recurrence. However, mesh fixation may increase postoperative chronic pain. This study aimed to describe the experience of a single surgeon at our institution performing this operation. Methods: We performed a retrospective review of the medical records of all patients who underwent bilateral laparoscopic totally extraperitoneal repair without mesh fixation for inguinal hernia from January 2005 to December 2011. Demographic, operative, and postoperative data were obtained for analysis. Results: A total of 343 patients underwent simultaneous bilateral laparoscopic totally extraperitoneal repair of 686 primary and recurrent inguinal hernias from January 2005 to December 2011. The mean operative time was 33 minutes. One patient was converted to an open approach (0.3%), and 1 patient had intraoperative bladder injury. Postoperative hematoma/seroma occurred in 5 patients (1.5%), wound infection in 1 (0.3%), hematuria in 2 (0.6%), and acute myocardial infarction in 1 (0.3%). Chronic pain developed postoperatively in 9 patients (2.6%); 3 of them underwent re-exploration. All patients were discharged home a few hours after surgery except for 3 patients. Among the 686 hernia repairs, there were a total of 20 recurrences (2.9%) in 18 patients (5.2%). Two patients had bilateral recurrences, whereas 16 had unilateral recurrences. Twelve of the recurrences occurred after 1 year (60%). Fourteen recurrences occurred among direct hernias (70%). Conclusion: Compared with the literature, our patients had fewer intraoperative and postoperative complications, less chronic pain, and no increase in operative time or length of hospital stay but had a slight increase in recurrence rate.

Mesh exposure is the major complication of vaginal prolapse repair. Incidence rates are variable according to the series. Mesh exposure usually occurs during the year following the intervention. We report here the first case of a patient with a late exposure of an anterior vaginal mesh 4 years after a surgical cystocele repair. The mesh has been easily removed at the operative theatre by vaginal approach.
Incidence of pain after inguinal hernia repair in the elderly. A retrospective historical cohort evaluation of 18-years’ experience with a mesh & plug inguinal hernia repair method on about 3000 patients
Background Chronic pain after prosthetic inguinal hernioplasty is one of the most important current issues in the current literature debate. Mechanisms related to pain development are only partially known. Influence of age as well as other factors is still unclear. The aim of this work was to evaluate whether development of chronic pain after open prosthetic plug and mesh inguinal hernioplasty is influenced by age. Methods Analysis was retrospectively conducted, dividing our cohort of patients (2,902) who had undergone prosthetic open plug&mesh inguinal hernioplasty from Jannuary 1994 to May 2012, following only the age criterion (cut-off 65 yrs.), into two groups (Gr.A<65 yrs, Gr.B>65 yrs.). All patients were routinely submitted to a postoperative questionnaire. Complications such as analgesic assumption were registered in both groups. Pain intensity was classified following the Visual Analogic Scale (VAS). Incidence of chronic pain, discomfort, and numbness, was assessed in both groups. Statistical significance was assessed by X2-test. Results Only 0.2% of patients suffered from a recurrence in our cohort. Postoperative chronic pain was observed in Gr. A in 0.12% of patients vs Gr.B 0.09% (p>0.05). Incidence of other postoperative symptoms such as discomfort or numbness were slightly prevalent on young patients (respectively p = 0.0286 and p = 0.01), while for hyperesthesia and sensation of foreign body no statistically significant difference of incidence between groups was observed. Conclusions Real chronic pain after inguinal hernioplasty is a rare clinical entity. Other causes of chronic pain should be accurately researched and excluded. In young patients psychological factors seem to show a slight influence. There was no influence of age on chronic postoperative pain incidence after inguinal hernioplasty. PMID:24268023
Objective: The extraperitoneal laparoscopic approach (EXTRA) has been shown to be an effective and safe repair for primary (PIH), recurrent (RIH) and bilateral hernia (BIH). There is very little data examining the merits of laparoscopic repair for hernias under local anesthesia. In this paper, we compare EXTRA performed under both general and local anesthesia. Methods: This nonrandomized prospective study was performed selectively on a male population only. Patients with associated pulmonary disease and high risk for general surgery were selected. Patients with recurrence and previous abdominal operations were excluded to decrease confounding variables in the study. A Prolene mesh was used in all patients. Results: Between May 1997 and September 1998, 92 male patients underwent the repair of 107 groin hernias using the EXTRA technique. The procedure was explained to them, and different anesthesia options were given. Fourteen of these repairs were performed under local anesthesia and 93 under general anesthesia. Of the 10 patients who underwent a repair under local anesthesia, there were 8 indirect, 5 direct and 1 pantaloon. The mean age was 53 years. In the group of general anesthesia, the types of hernias repaired were 45 indirect, 30 direct and 11 pantaloon. The mean age was 45 years. The mean follow-up was 15 months. Each patient was sent home the same day. Two peritoneal tears were recorded in the first group. The operative time was longer in the local group (47 ± 11 vs 18 ± 3). None of the patients required conversion to an open technique or change of anesthesia. No recurrences were found in either group. The average time of return to work and regular activity was 3.5 ± 1 and 3 ± 1 days, respectively. Conclusion: There appears to be no significant difference in recurrence and complication rates when the EXTRA is performed under local anesthesia as compared to general. Blunt dissection of the preperitoneal space does not trigger pain and does not require

The aim of the current prospective study was to show the results of a new type of medium-weight monofilament polypropylene mesh covered with a hydrogel barrier on the visceral side. Between July 2011 and April 2013 prospectively collected data on 30 consecutive patients who underwent abdominal wall hernia repair using a medium-weight mesh covered with carboxymethylcellulose-sodiumhyaluronate coating (Ventralight™ ST mesh, Davol Inc, Subsidary of C. R. Bard, Inc. Warwick, RI) were analyzed. Out of these patients, those who had a follow-up of at least 12 months were selected. Short- and long-term outcomes were described. Meanwhile, registration continues up to completion of a series with 100 included patients. A total of 17 patients were selected (men/women ratio 11/6). Median follow-up was 12 months (range 12-21). Mean hernia diameter was 7 cm x 5 cm (craniocaudal x laterolateral) (range 1.5 x 1.5 to 20 x 15). Mean length of hospital stay was 6.1 days. Postoperative Visual Analogue Scale (VAS) at last follow-up was significantly lower than the preoperative VAS (P = 0.017) There were no intraoperative complications. Four patients (23%) developed minor complications. Two patients had mild discomfort, another two patients developed a seroma. No recurrences were observed. This intermediate study shows good results using a biofilm coated mesh and confirm the positive results obtained in the Sasse clinical trial.

Introduction Totally extra-peritoneal (TEP) inguinal hernia repair allows identification and repair of incidental non-inguinal groin hernias. We assessed the prevalence of incidental hernias during TEP inguinal hernia repair and identified the risk factors for incidental hernias. Materials and Methods Consecutive patients undergoing TEP repair from May 2005 to November 2012 were the study cohort. Inspection for ipsilateral femoral, obturator and rarer varieties of hernia was undertaken during TEP repair. Patient characteristics and operative findings were recorded on a prospectively collected database. Results A total of 1,532 TEP repairs were undertaken in 1,196 patients. Ninety-three patients were excluded due to incomplete data, leaving 1,103 patients and 1,404 hernias for analyses (1,380 male; 802 unilateral and 301 bilateral repairs; median age, 59 years). Among the 37 incidental hernias identified (2.6% of cases), the most common type of incidental hernia was femoral (n=32, 2.3%) followed by obturator (n=2, 0.1%). Increasing age was associated with an increased risk of incidental hernia, with a significant linear trend (p<0.01). The risk for patients >60 years of age was 4.0% vs 1.4% for those aged <60 years (p<0.01). Incidental hernias were found in 29.2% of females vs 2.2% of males, (p<0.0001). Risk of incidental hernia in those with a recurrent inguinal hernia was 3.0% vs 2.6% for primary repair (p=0.79). Conclusions Incidental hernias during TEP inguinal hernia repair were found in 2.6% of cases and, though infrequent, could cause complications if left untreated. The risk of incidental hernia increased with age and was significantly higher in patients aged >60 years and in females. PMID:25723688

Giant inguinal hernia are usually found in developing countries due to delay in seeking medical attention. The management of such hernias may sometimes require procedures to increase the intra-peritoneal capacity prior to the repair of the giant hernia. Otherwise patients may develop abdominal compartment syndrome leading to various unwanted complications. Primary repair of giant hernias are possible in some cases without having significant post-operative complications. In this present case series, we have managed a total of four patients of giant inguinal hernia by primary repair without much post-operative complications. PMID:28384934

Purpose To describe the clinical characteristics and outcomes after inguinal hernia repair in overweight and obese patients. Methods We retrospectively reviewed the medical records of 636 adult patients who underwent mesh plug inguinal hernia repair performed by one surgeon from November 2001 to January 2009.The clinical characteristics and surgical outcomes of the patients were analyzed. According to the body mass index, patients higher than 23 were defined as overweight and obese patient group (O group) and patients between 18.5 and 23 were defined as normal weight patient group (N group). Seventeen underweight patients were excluded in this study. Results Of 619 cases, the number for O group was 344 (55.6%) and for N group was 275 (44.4%). The mean age was significantly higher in N group (62.2 ± 12.6 vs. 64.4 ± 14.8, P = 0.048). Underlying diseases were present in 226 (65.7%) of the O group and 191 (69.5%) of the N group (P = 0.322). Anesthesia method, operative time and postoperative hospital stay had no significant difference between the two groups. Postoperative complications developed in 41 (11.9%) of the O group and in 28 (10.2%) of the N group, respectively, and no major complications developed in either group. Conclusion Adult inguinal hernias developed at a relatively younger age in overweight and obese patients than in normal weight patients. There were no specific differences in other clinical characteristics and outcomes between the two groups. Therefore inguinal hernia repair in overweight and obese patients is a safe procedure as in normal weight patients. PMID:22066122

A patient presented with a recurrent incarcerated inguinoscrotal hernia requiring urgent surgery. The defect was through the gap in the mesh left originally for the cord structures. As a result, a modified funnel repair was performed. An innovative approach was adopted that was best suited to tackling and reducing the risk of recurrence.

Laparoscopic herniorrhaphy is becoming an increasingly common procedure. The possible creation of intraperitoneal adhesions during laparoscopic herniorrhaphy has not been examined. For the transperitoneal hernia repair to be an acceptable option, the hypothesis that this approach will incite significant adhesions must be rejected. To test this hypothesis, 21 pigs underwent laparoscopic herniorrhaphy using a standard procedure with the implantation of a polypropylene mesh graft on one side while a sham procedure was performed on the other. These animals were later examined laparoscopically for adhesion formation and the condition of the graft. None of the 21 animals developed adhesions to the trocar sites, 12 animals developed adhesions to the area of the polypropylene mesh, and 3 developed adhesions to the side of the sham procedure. There were no adhesions involving the small intestine. It is therefore concluded that the hypothesis should be rejected and that laparoscopic herniorrhaphy does not incite significant adhesions.

Although the laparoscopic technique is a new approach to groin hernia, it is becoming more widely accepted as an alternative to traditional open techniques. This study is a preliminary review of complications and recurrences. A questionnaire specific for complications was sent to each investigator. From 12/89 to 4/93, 1,514 hernias were repaired; 119 (7.8%) were bilateral and 192 (12.7%) recurrent. There were 860 indirect, 560 direct, 43 pantaloon, 37 femoral, and 6 obturator hernias, and 8 were not specified; 553 were repaired using a transabdominal preperitoneal mesh technique (TAPP), 457 with a total extraperitoneal technique (TEP), 320 with intraperitoneal onlay mesh (IPOM), 102 by ring closure, and 82 involved plug and patch technique. Eighteen intraoperative and 188 postoperative complications were seen. The total complication rate was 13.6%, of which 1.2% were intraoperative. Of the intraoperative complications, 12 were related to the laparoscopic technique, three were related to the hernia repair, and one was related to anesthesia. The rate of conversion to open was 0.8%. Of the postoperative complications, there were 95 local, 25 neurologic, 23 testicular, 23 urinary, 10 mesh, and 12 miscellaneous. There were 34 recurrences after the 1,514 hernia repairs (2.2%). The follow-up was reported in 825 patients for an average of 13 months. The recurrence rate varied drastically with the technique: A 22% recurrence rate after the plug and patch vs 3%, 2.2%, 0.7%, and 0.4% with the ring closure, IPOM, TAPP, and TEP, respectively. Laparoscopic repair of groin hernia can be safely performed. Complications, mostly minor, diminish with experience. The recurrence rate is less with large mesh which is anchored.

A prospective study of outcome after inguinal hernia repair in patients undergoing simultaneous repair of bilateral hernias (n = 31), sequential repair of bilateral hernias (n = 5), and unilateral hernia repair (n = 75) is reported. There were no differences in wound complications, post-operative respiratory complications, or other adverse effects in the three groups. Operating time was similar in the unilateral and bilateral simultaneous repairs (median 55 min), but was longer (100 min) for the combination of two sequential repairs. Hospital stay was shortest for patients undergoing unilateral repair (2 days) but was less with bilateral simultaneous repair (4 days) than after two sequential repairs (total of 6 days). There were 12 (11%) wound complications of which five (5%) were infections. There was no difference in complication rate between unilateral and bilateral hernia repair. Postoperative recovery was assessed prospectively and was recorded at 1 month. There was no difference between unilateral and bilateral simultaneous repairs in the number of days before the patient was able to climb stairs easily, drive a car or return to work. The duration of the requirement for analgesia was similar in each group. We conclude that bilateral simultaneous hernia repair can be carried out with no greater morbidity than a unilateral repair, and the return to normal activity is as rapid. Bilateral hernias should be repaired simultaneously rather than sequentially. PMID:2221764

The rising use of endovascular techniques utilizing femoral artery access may increase the frequency with which surgeons face the challenge of hernia repair in reoperative groins—which may or may not include a vascular graft. We present a case where a vascular graft contributed to an acute presentation and complicated dissection, and review the literature. A 67-year-old man who had undergone prior endovascular aneurysm repair via open bilateral femoral artery access and concomitant prosthetic femorofemoral bypass, presented with an incarcerated, scrotal inguinal hernia. The graft with its associated fibrosis contributed to the incarceration by compressing the inguinal ring. Repair was undertaken via an open, anterior approach with tension-free, Lichtenstein herniorraphy after releasing graft-associated fibrosis. Repair of groin hernias in this complex setting requires careful surgical planning, preparation for potential vascular reconstruction and meticulous technique to avoid bowel injury in the face of a vascular conduit and mesh.

Background Family history, male gender and age are significant risk factors for inguinal hernia disease. Family history provides evidence for a genetic trait and could explain early recurrence after inguinal hernia repair despite technical advance at least in a subgroup of patients. This study evaluates if age and family history can be identified as risk factors for early recurrence after primary hernia repair. Methods We performed an observational cohort study for 75 patients having at least two recurrent hernias. The impact of age, gender and family history on the onset of primary hernias, age at first recurrence and recurrence rates was investigated. Results 44% (33/75) of recurrent hernia patients had a family history and primary as well as recurrent hernias occurred significantly earlier in this group (p = 0.04). The older the patients were at onset the earlier they got a recurrent hernia. Smoking could be identified as on additional risk factor for early onset of hernia disease but not for hernia recurrence. Conclusion Our data reveal an increased incidence of family history for recurrent hernia patients when compared with primary hernia patients. Patients with a family history have their primary hernias as well as their recurrence at younger age then patients without a family history. Though recurrent hernia has to be regarded as a disease caused by multiple factors, a family history may be considered as a criterion to identify the risk for recurrence before the primary operation.

This report describes a diagnostic dilemma and what we believe to be a previously unreported case of a stitch sinus caused by the presence of a non-absorbable centring suture used during laparoscopic mesh repair of an umbilical hernia. Successful treatment was achieved through umbilical excision and removal of the offending suture; the patient's recovery thereafter was uneventful. Surgeons should be aware of this complication when consenting patients and should consider the use of absorbable sutures to minimize such risk in similar procedures. In addition, clinicians may add this to their list of differential diagnoses in a patient presenting with pain, discharge or what appears to be a recurrence of their hernia following laparoscopic mesh repair of an umbilical hernia.

We present the case of a male Japanese patient with a giant inguinal hernia that extended to his knees while standing. A transabdominal pre-peritoneal (TAPP) repair was performed under general anesthesia. Complete reduction of the contents of the hernia was achieved within 2 h 50 min. A blood loss of approximately 700 ml was noted. The patient was discharged from the hospital on post-operative Day 12, with no recurrence of the hernia 6 months post-surgery. Factors contributing to the successful outcomes included preparation of several reduction methods before surgery, use of a large size mesh and implementation of pre-operative measures to prevent abdominal compartment syndrome. Further studies are required to evaluate the feasibility of laparoscopic repair in the management of giant inguinal hernia. PMID:27672103

Laparoscopic ventral hernia repair (LVHR) has grown in popularity. Typically, this procedure is performed with a mesh bridge technique that results in high rates of seroma, eventration (bulging), and patient dissatisfaction. In an effort to avoid these complications, there is growing interest in the role of laparoscopic primary fascial closure with intraperitoneal mesh placement. This systematic review evaluated the outcomes of closure of the central defect during LVHR. A literature search of PubMed, Cochrane databases, and Embase was conducted using PRISMA guidelines. MINORS was used to assess the methodologic quality. Primary outcome was hernia recurrence. Secondary outcomes were surgical-site infection, seroma formation, bulging, and patient-centered items (satisfaction, chronic pain, functional status). Eleven studies were identified, eight of which were case series (level 4 data). Three comparative studies examined the difference between closure and nonclosure of the fascial defect during laparoscopic ventral incisional hernia repairs (level 3 and 4 data). These studies suggested that primary fascial closure (n = 138) compared to nonclosure (n = 255) resulted in lower recurrence rates (0-5.7 vs. 4.8-16.7 %) and seroma formation rates (5.6-11.4 vs. 4.3-27.8 %). Follow-up periods for both groups were similar (1-108 months). Only one study evaluated patient function and clinical bulging. It showed better outcomes with primary fascial closure. Closure of the central defect during LVHR resulted in less recurrence, bulging, and seroma than nonclosure. Patients with closure were more satisfied with the results and had better functional status. The quality of the data was poor, however. A randomized controlled trial to evaluate the role of closure of the central defect during LVHR is warranted.

In this study, 101 consecutive laparoscopic transabdominal preperitoneal hernia repairs (LTPR) were performed in 62 patients by a single surgeon. The series was begun in April 1991, and involved repair of 49 direct, 41 indirect, 4 femoral, 3 umbilical, 3 sliding, and 1 incisional hernias. Twelve cases were bilateral, eleven hernias were incarcerated, and fifteen hernias were recurrent. There were no intraoperative complications, and none of the procedures required conversion to open surgery. Patients experienced the following postoperative complications: transient testicular pain (1), transient anterior thigh paresthesias (2), urinary retention requiring TURP (1), and hernia recurrences (2). Follow up has ranged from 4 - 15 months and initial results have been encouraging.
Background Prolene Hernia System (PHS) is a bi-layered polypropylene mesh with a connector that combines the anterior and posterior inguinal hernia repair, but still not very popular in this part of the country. Hence a prospective & randomized comparative study was undertaken to compare PHS with the already popular Lichtenstein Hernia Repair (LHR) and determine the post-operative outcome. Materials and Methods Total 67 inguinal hernia repairs were randomly assigned to either PHS or LHR method, and data was collected regarding various outcome measures like duration of surgery, post-operative pain, requirement of analgesia, return to normal activity, and early and late complications. Results Mean duration of surgery was significantly higher for PHS group than LHR group (65.4 min vs 51.26 min, p-value <0.0001). Significant difference was noted between the PHS and LHR group in terms of moderate to severe post-operative pain (15.15% vs 41.18%,p-value 0.018), time of requirement of analgesia (3.7 vs 4.6 days, p-value 0.024), and time to return to normal activity (2.7 vs 3.4 days, p-value 0.023), all in favour of the former technique. No intra-operative complication was noted in either of the groups. 5 patients had early complications in PHS group and 6 in LHR group, but this was statistically not significant. The average time of follow-up for the study was 7.8 month, ranging from 1 to 18 months. Chronic inguinal pain was noted in 1 and 2 patients respectively in PHS and LHR group, again statistically not significant. No recurrence was noted in both the groups till the time of follow-up. Conclusion PHS is a safe and better alternative to the time honored Lichtenstein hernia repair with the added advantage of strengthening whole of myopectineal orifice, and virtually eliminating any risk of recurrence.

The repair of incisional hernias with the use of prosthetic biomaterials is the standard of care today. There are different prosthetic biomaterials that can be used to repair incisional hernias. These materials can be divided into products that are single component or a combination. Incisional hernia repair using the intraperitoneal implantation of a prosthesis requires mesh with impervious properties. This is preliminary study with a new composite non resorbable mesh in polyethylene terephthalate-polyurethane (HI-TEX PARP MP) used for incisional hernia repair in intraperitoneal implantation. This mesh has one permeable side in polyethylene terephthalate (PET) for rapid tissue fixation and another side in polyurethane (PEU), hydrophobic in order to avoid cell penetration. This is a preliminary study of medical records of 24 patients (17 women and 7 men) in whom intraperitoneal placement of composite prosthetics in polyethylene terephthalate-polyurethane (HI-TEX PARP MP) was used between September 2004 and September 2006. The incisional hernias were recurrent in 8 patients. The underside of the mesh was placed in direct contact with the visceral peritoneum, whereas the upper side made contact with the subcutaneous tissue. No intraoperative complications occurred. Postoperatively, 1 had seromas, 1 had phlegmon of the wound without removing prosthetics. There was 1 death but not dependent of the surgical performance. The follow-up, was 12 months (range 1 month-2 years); none had discomfort; only one patient had recurrence. Intraperitoneal placement of HI-TEX PARP MP has several advantages over other techniques including minimal adhesions, a decreased risk of infection and recurrences. In addition this mesh is more economics than the other prosthetics in use.

Introduction Parastomal hernia is described as the most common complication in patients with ostomy. It is reported that its incidence varies from 3% to 39% for colostomies and 0 to 6% for ileostomies. Surgical repair remains the treatment of choice. There are three types of surgical treatment – fascial repair, stoma relocation and repair using prosthetic mesh via a laparoscopic or open approach. Recently there have been several meta-analyses and systematic reviews aiming to compare the results of surgical treatment, and the authors agreed that the quality of evidence precludes firm conclusions. Aim To describe the novel concept of parastomal hernia repair – HyPER/SPHR technique (hybrid parastomal endoscopic re-do/Szczepkowski parastomal hernia repair) and its early results in 12 consecutive cases. Material and methods Twelve consecutive patients were operated on due to parastomal hernia using the new HyPER hybrid technique between June 2013 and May 2014. The patients’ condition was evaluated during the perioperative period, 6 weeks and then every 3 months after surgery. Results After 6 weeks of follow-up we have not observed any mesh-related complications. All 12 patients were examined 3 months and 6 months after repair surgery for evaluation. No recurrence, stoma site infection or stoma-related problems were found. None of the patients complained of pain and none of them needed to be hospitalized again. Reported quality of life on a 0–10 scale after 6 weeks of follow-up was 8 (range: 7–10). Conclusions The HyPER procedure for treatment of parastomal hernias proposed by the authors is a safe and feasible surgical technique with a high patient satisfaction rate and a low number of complications. The hybrid procedure seems to be a promising method for parastomal hernia repair. PMID:25960785

In the last 10 years in Germany we have seen a lot of hernia repairs using mesh.Meta-analysis shows the advantages of using meshes in hernia surgery; recurrence rates in inguinal hernia surgery are less than 3% in studies. There is some discussion about minimally invasive surgery in Germany.In incisional hernia surgery there is no discussion about using meshes. The role of minimally invasive surgery has not yet been defined.

We report a rare case of visceral injury after totally extraperitoneal endoscopic inguinal hernia repair. A 48-year-old man underwent needlescopic totally extraperitoneal repair of a direct inguinal hernia. Bleeding from a branch of the inferior epigastric vessels occurred at the beginning of the extraperitoneal dissection with a monopolar electrosurgical device. Hemostasis was prolonged. However, herniorrhaphy and mesh repair were successfully performed, and no peritoneal disruption or pneumoperitoneum was visible. The patient was discharged home on the next day. However, 30 h after this operation, he underwent diagnostic and operative laparoscopy because of acute abdominal pain. Ileal perforation was found and repaired, and pathological examination indicated cautery artifact. Thus, thermal damage to the ileum during the initial operation may have caused the bowel perforation. To the best of our knowledge, no other cases of bowel perforation after totally extraperitoneal repair without peritoneal disruption have been reported.

The permanent implantation of a polypropylene mesh during inguinal hernia repair causes chronic inflammatory changes in the surrounding tissue. We investigated the effect of this foreign body reaction on the structures of the spermatic cord in the rabbit. Eight Chinchilla rabbits underwent unilateral inguinal hernia repair by the Lichtenstein technique using Marlex (n = 4) or Ultrapro (n = 4) mesh. The contralateral side was operated upon using the Shouldice repair. Three animals served as controls. Three months after operation we analyzed testicular size, testicular temperature, and arterial perfusion by excitation light of a 780-nm laser after injection of 0.5 mg/kg indocyanin green. Histological evaluation included spermatogenesis (Johnsen score) and foreign-body reaction. Testicular volume increased about 10% after each operation. The decrease of arterial perfusion and testicular temperature was more significant after mesh repair than following Shouldice operation. After mesh implantation we found fewer seminiferous tubules classified as Johnsen 10 (Marlex: 51.3%, Ultrapro: 45.0%) than after Shouldice repair (63.8%) or in the controls (65.8%). The spermatic cord showed a typical foreign-body reaction at the interface between mesh and surrounding tissue, which was not detectable after Shouldice repair. Preserved cremasteric muscle fibers protected the structures of the spermatic cord. The inflammatory foreign-body reaction of the surrounding tissue induced by the inguinal prosthetic mesh includes the structures of the spermatic cord. This may have an influence also on spermatogenesis. Therefore, we recommend strict indications for implantation of a prosthetic mesh during inguinal hernia repair.

Severe pain is usual after laparoscopic ventral hernia repair (LVHR). Mesh fixation with titanium tacks may play a key role in the development of acute and chronic pain and alternative fixation methods should therefore be investigated. This PhD thesis was based on three studies and aimed too: 1) assess the intensity and impact of postoperative pain by detailed patient-reported description of pain and convalescence after LVHR (Study I), 2) evaluate the feasibility of fibrin sealant (FS) for mesh fixation in an experimental pig model (Study II), and 3) investigate FS vs. tacks for mesh fixation in LVHR in a randomised, double-blinded, clinical controlled study with acute postoperative pain as the primary outcome (Study III). In Study I - a prospective descriptive study - 35 patients were prospectively included and underwent LVHR. Scores of pain, quality of life, convalescence, fatigue, and general well-being were obtained from each patient. Follow-up was six months. Average pain from postoperative day (POD) 0-2 and POD 0-6 measured on a 0-100 mm visual analogue scale (VAS) was 61 and 48, respectively. Pain scores reached preoperative values at POD 30. The incidence of severe chronic pain was 7%. No parameter predicted postoperative pain significantly. Significant correlations were found between pain, and general well-being (rS= -0.8, p < 0.001), satisfaction (rS= -0.67, p < quality of life score (rS= -0.63, p < 0.001) six months postoperatively. Patients resumed normal daily activity at POD 14. In Study II - a randomised experimental study in pigs - nine pigs were operated laparoscopically with insertion of two different meshes fixed with either FS or tacks. All pigs were euthanized on POD 30. The primary outcome parameter was strength of ingrowth between the mesh and the anterior abdominal wall. A mechanical peel test was performed for each tissue sample. The secondary outcome parameters were grade and strength of adhesions to the mesh, shrinkage and displacement

Introduction: Endoscopic surgical repair of inguinal hernia is currently conducted using 2 techniques: the totally extraperitoneal (TEP) and the transabdominal (TAPP) hernia repair. The TEP procedure is technically advantageous, because of the use of no mesh fixation and the elimination of the peritoneal flap, leading to less postoperative pain and faster recovery. The drawback is that TEP is not performed as frequently, because of its complexity and longer learning curve. In this study, we propose a hybrid technique that could potentially become the gold standard of minimally invasive inguinal hernia surgery. This will be achieved by combining established advantages of TEP and TAPP associated with the precision and cosmetics of minilaparoscopy (MINI). Materials and Surgical Technique: Between January and July 2011, 22 patients were admitted for endoscopic inguinal hernia repair. The combined technique was initiated with TAPP inspection and direct visualization of a minilaparoscopic trocar dissection of the preperitoneum space. A10-mm trocar was then placed inside the previously dissected preperitoneal space, using the same umbilical TAPP skin incision. Minilaparoscopic retroperitoneal dissection was completed by TEP, and the surgical procedure was finalized with intraperitoneal review and correction of the preperitoneal work. Discussion: The minilaparoscopic TEP-TAPP combined approach for inguinal hernia is feasible, safe, and allows a simple endoscopic repair. This is achieved by combining features and advantages of both TAPP and TEP techniques using precise and sophisticated MINI instruments. Minilaparoscopic preperitoneal dissection allows a faster and easier creation of the preperitoneal space for the TEP component of the procedure. PMID:23484566

Parastomal hernia is one of the most common stoma related complication, with the correlated risk of incarceration, obstruction, and strangulation. The incidence is high (30-50%) and depends on the length of follow up. Different surgical options for repairing are defective with a 25-70% failure and recurrence rate. Prevention of parastomal hernia with mesh reinforcement seems to be effective. Three available trials are recruiting patients: Prism (with matrix porcine prothesis), Prevent (with preperitoneal polypropylene mesh), and the stapled polypropylene mesh stoma reinforcement technique (SMART). We performed the SMART procedure in six patients undergoing definitive colostomy. Our cases show that the procedure is rapid (duration range 15-20 minutes), cost effective (500 euro), and safe (in our experience, there are no post-surgical complications that are procedure-related). A long term follow-up and a higher number of patients will give us confirmation of the initial hopeful results.

Trocar injuries to the small bowel during laparoscopic hernia repair are a rare complication, the most common complications being postoperative neuralgias, scrotal swelling, scrotal ecchymosis, and hematoma. A 15-year-old boy was admitted 5 days status-post transabdominal laparoscopic inguinal hernia repair of a symptomatic right pantaloon hernia, with signs and symptoms of a retrocecal abscess. Despite laparotic intervention and appendectomy, the next 2 years passed with almost daily, purulent, right lower quadrant wound drainage, in an otherwise asymptomatic patient. Superficial wound exploration and sinogram in 1996 revealed a sinus tract in direct communication with the small bowel. Elective laparotomy in December 1997 involved a successful resection of a 2.5-cm fistula with involved mesh, and the communicating small bowel through a midline incision, followed by a primary closure of the small-bowel opening. The patient has recovered without complications.

Objective To describe a 7-year experience with recurrent inguinal hernia repair performed mainly with tension-free mesh or plug technique under local anesthesia through the anterior approach, and to evaluate the safety and effectiveness of this method of treatment. Methods One hundred forty-five elective and 1 emergency herniorrhaphies for recurrent groin hernia were performed in 141 subjects (134 men and 7 women) with a mean age of 65 years (range 30–89). Concomitant medical and surgical problems were present in 73% and 8% of subjects, respectively. In 28 instances, the relapsed hernia had already been operated on once or twice for recurrence. A traditional hernioplasty had been previously performed in the vast majority of cases (136). Tension-free mesh or plug techniques through an anterior approach under local anesthesia were performed in 144 reoperations. Preperitoneal mesh repair and general or spinal anesthesia were used in all but one case when herniorrhaphy was performed during simultaneous operations. Results Mean hospital stay after surgery was 1.5 days (range 3 hours–14 days). No perioperative deaths occurred in this series. General complications were one case of acute intestinal bleeding and two cases of urinary retention. Local complications consisted of eight (5.5%) minor complications and one case of orchitis (0.7%) followed by testicular atrophy. In no instance was postoperative neuralgia or chronic pain reported. Two re-recurrences occurred. Conclusions Given the low complication rate in this and other reported series and the absence of surgical or general complications described after preperitoneal open or laparoscopic repair and after general and spinal anesthesia, anterior mesh repair under local anesthesia seems to be a low-cost surgical technique that can be safely and effectively used even in a teaching hospital for the treatment of the majority of patients with recurrent groin hernias.

Routine hernia repair surgery involves the implant of synthetic mesh. However, this type of procedure may give rise to pain and bowel incarceration and strangulation, causing considerable patient disability. The purpose of this study was to compare the long-term behaviour of three commercial meshes used to repair the partially herniated abdomen in New Zealand White rabbits: the heavyweight (HW) mesh, Surgipro(®) and lightweight (LW) mesh, Optilene(®), both made of polypropylene (PP), and a mediumweight (MW) mesh, Infinit(®), made of polytetrafluoroethylene (PTFE). The implanted meshes were mechanical and histological assessed at 14, 90 and 180 days post-implant. This behaviour was compared to the anisotropic mechanical behaviour of the unrepaired abdominal wall in control non-operated rabbits. Both uniaxial mechanical tests conducted in craneo-caudal and perpendicular directions and histological findings revealed substantial collagen growth over the repaired hernial defects causing stiffness in the repair zone, and thus a change in the original properties of the meshes. The mechanical behaviour of the healthy tissue in the craneo-caudal direction was not reproduced by any of the implanted meshes after 14 days or 90 days of implant, whereas in the perpendicular direction, SUR and OPT achieved similar behaviour. From a mechanical standpoint, the anisotropic PP-lightweight meshes may be considered a good choice in the long run, which correlates with the structure of the regenerated tissue.

Large hiatal hernias are notorious for their high recurrence rates after conventional repair. Recurrence rates have been described to be higher in obese patients due to increased intra-abdominal pressure. We hypothesized that patients who undergo hiatal hernia repair (HHR) with bariatric surgery (BAR) will have a lower hernia recurrence rate when compared to patients who undergo HHR with fundoplication (FP) due to the decrease in intra-abdominal pressure observed with weight loss. This was an Institutional Review Board approved retrospective review. The outcomes of patients who underwent HHR+BAR as well as patients who had HHR+FP only from 2007 to 2014 were reviewed. Patients who had small hiatal hernias (<2 cm), underwent an anterior repair, or had gastropexy only were excluded. The primary outcome was hernia recurrence and reflux resolution. The outcomes of 58 patients who had HHR+BAR were compared with 30 patients with HHR+FP. Hernia recurrence rate for HHR+BAR was 12 per cent, whereas hernia recurrence rate for HHR+FP was 38 per cent (P < 0.01). Reflux resolution for HHR+FP was 78 per cent, whereas reflux improvement rate for HHR+BAR was 84 per cent (P = n.s.). Combining HHR with BAR leads to a lower hernia recurrence rate when compared to patients who undergo HHR with FP.

Testicular atrophy is an uncommon but well recognized complication of inguinal hernia repair and one that frequently results in litigation. A series of ten cases of testicular atrophy occurring after hernia repair in nine patients is presented. Identifiable risk factors were present in eight instances. Surgeons should make careful enquiries as to previous groin or scrotal surgery and, when indicated, warn the patient before surgery of the increased risk of testicular atrophy. Overzealous dissection of a distal hernia sac, dislocation of the testis from the scrotum into the wound and concomitant scrotal surgery should all be avoided.

Planned ventral hernia is a management strategy in which the abdominal fascial layer has been left unclosed and the viscera are covered only with original or grafted skin. Leaving the fascia open can be deliberate or unavoidable and most commonly results from staged repair of the abdominal wall due to trauma, peritonitis, pancreatitis, abdominal vascular emergencies, or abdominal compartment syndrome. The abdominal wall defects can be categorized as type I or II defects depending on whether there is intact, stable skin coverage. In defects with intact skin coverage, the most commonly used methods are the components separation technique and a prosthetic repair, sometimes used in combination. The advantages of the components separation technique is the ability to close the linea alba at the midline, creating a better functional result than a repair with inert mesh. Although the reherniation risk seems higher after components separation, the risk of infection is considerably lower. With a type II defect, with absent or unstable skin coverage, fascial repair alone is inadequate. Of the more complex reconstruction techniques, the use of a free tensor fasciae latae (TFL) flap utilizing a saphenous vein arteriovenous loop is the most promising. The advantages of the TFL flap include constant anatomy of the pedicle, a strong fascial layer, large-caliber vessels matching the size of the AV loop, and the ability to use large flaps (up to 20 × 35 cm). Whatever technique is used, the repair of complex abdominal wall defects requires close collaboration with plastic and abdominal surgeons, which is best managed in specialized centers.

Purpose We evaluated the adequacy and feasibility of a tumescent solution containing lidocaine and bupivacaine for inguinal hernia repairs. Methods The medical records of 146 consecutive inguinal hernia patients with 157 hernia repairs using the tumescent local anesthesia technique performed by a single surgeon between September 2009 and December 2013 were retrospectively reviewed. Results The mean operation time (±standard deviation) and hospital stay were 64.5 ± 17.6 minutes and 2.7 ± 1.5 days. The postoperative complication rate was 17.8%. There were four cases of recurrences (2.5%) at a mean follow-up of 24 ± 14 months. Conclusion Our results suggest that local anesthesia with the tumescent technique is an effective and safe modality for inguinal hernia repairs. PMID:25485241

Introduction: Intrapericardial diaphragmatic hernia is a rare injury. We present a case of an intrapericardial diaphragmatic hernia from blunt trauma. In this report we will review the current literature and also describe the first report of a primary laparoscopic repair of the defect. Case Description: A 38-year-old unrestrained male passenger had blunt chest and abdominal trauma from a motor vehicle collision. Two months later, on a computed tomography scan, he was found to have an intrapericardial diaphragmatic hernia. The defect was repaired primarily through a laparoscopic approach. Discussion: Symptoms of intrapericardial diaphragmatic hernia are chest pain, upper abdominal pain, dysphagia, and dyspnea. Chest computed tomography is the most useful diagnostic test to define the defect. Even when the injury is diagnosed late, laparoscopy can be used for primary and patch repair. PMID:24960502

An estimated overall complication rate of approximately ten percent is found in the half million patients who annually undergo groin hernia repair in the United States. Certain features in the operative technique are emphasized which should prevent many of these complications.Intraoperative complications during the groin hernia repair are primarily hemorrhage and injury to the vas deferens, the three nerves in the area, the vascular supply of the testis, and the abdominal and pelvic viscera. Miscellaneous intraoperative complications relate to problems associated with the repair of massive hernias, missed hernia, and the loss of strangulated bowel into the abdominal cavity.Early postoperative complications may be either systemic or local with cardiac and respiratory conditions comprising the former group. The early local complications are primarily wound problems of infection, hematoma formation, and scrotal swelling involving the skin and testis. High ligation in excision of the sac in all hernias, repair of the defect in the plane of its occurrence, and suture of fascia to fascia in the same plane without tension are the basic tenets of inguinal hernia repair which should result in a low incidence of recurrence.The most effective prophylactic measures necessary for the prevention of complications considered are a thorough knowledge of inguinofemoral anatomy, mature surgical judgment, and meticulous surgical technique.

The objective of this study was to describe outcomes for patients who underwent titanium mesh reconstruction of full-thickness nasal defects without internal lining repair. This is a retrospective cohort study. Patients with through-and-through nasal defects were identified at a single academic institution between 2008 and 2016. Nasal reconstruction was performed with either titanium mesh and external skin reconstruction without repair of the intranasal lining or traditional three-layer closure. Five patients underwent titanium mesh reconstruction and 11 underwent traditional three-layer repair. Median follow-up was 11 months (range, 2-66 months). The only significant difference between groups was older age in patients undergoing titanium reconstruction (mean, 81 vs. 63 years; difference of 18; 95% confidence interval [CI], 4-32 years). Defect extent including overall size and structures removed was similar between groups (p > 0.05). Paramedian forehead flap was the most common external reconstruction in both groups (100% for titanium mesh and 73% for three-layer closure). Time under anesthesia was significantly shorter for titanium mesh reconstruction (median, 119 vs. 314 minutes; difference of 195; 95% CI, 45-237). Estimated blood loss and length of hospital stay were similar between groups (p > 0.05). Complication rates were substantial although not significantly different, 40 and 36% in titanium and three-layer reconstruction, respectively (p > 0.05). All patients with complications after titanium reconstruction had prior or postoperative radiotherapy. Titanium mesh reconstruction of through-and-through nasal defects can successfully be performed without reconstruction of the intranasal lining, significantly decreasing operative times. This reconstructive technique may not be suitable for patients who undergo radiotherapy.
The co-occurrence of incisional and parastomal hernias (PSH) remains a surgical challenge. Standardized treatment guidelines are missing, and the patients concerned require an individualized surgical approach. The laparoscopic techniques can be performed with incised and/or stoma-lateralizing flat meshes with intraperitoneal onlay placement. The purely laparoscopic and laparoscopic-assisted approaches with 3-D meshes offer advantages regarding the complete coverage of the edges of the stomal areas and the option of equilateral or contralateral stoma relocation in cases of PSH, which are difficult to handle due to scarring, adhesions, and large fascial defects > 5 cm with intestinal hernia sac contents. A relevant stoma prolapse can be relocated by tunnel-like preformed 3-D meshes and shortening the stoma bowel. The positive effect on prolapse prevention arises from the dome of the 3-D mesh, which is directed toward the abdominal cavity and tightly fits to the bowel. In cases of large incisional hernias (> 8-10 cm in width) or young patients with higher physical demands, an open abdominal wall reconstruction in sublay technique is required. Component separation techniques that enable tension-free ventral fascial closure should be preferred to mesh-supported defect bridging methods. The modified posterior component separation with transversus abdominis release (TAR) and the minimally invasive anterior component separation are superior to the original Ramirez technique with respect to wound morbidity. By using 3-D textile implants, which were specially designed for parastomal hernia prevention, the stoma can be brought out through the lateral abdominal wall without increased risk of parastomal hernia or prolapse development. An algorithm for surgical treatment, in consideration of the complexity of combined hernias, is introduced for the first time.

Even after more than 100 years of inguinal hernia repair, the rate of complications and recurrence remains unacceptably high. In the last decades, few effective advances in surgical technique and materials have been made. The authors see them as minor adjustments in the shape and materials of the prosthetic implants. Still, the underlying genesis of inguinal hernia remains undefined. Based upon this, it seems the surgical repair of inguinal protrusions cannot be based upon the pathogenesis because the etiology to date has not been addressed. Most hernia repairs are performed with some degree of point fixation (sutures/tacks) to stop the mesh from migrating and creating high recurrence rates. This should be a priority for our considerations, as fixating mesh puts it in stark contrast to the physiology and dynamics of the myotendineal structures of the groin. Following years of surgical practice, implant fixation, mesh shrinkage, and poor quality of tissue ingrowth still represent an unresolved issue in modern hernia repair. Conventional prosthetics used for inguinal hernia repair are static and passive. They do not move in harmony with the dynamic elements of the groin structure and, as a result, induce the ingrowth of thin scar plates or shrinking regressive tissue that colonizes the implants. The authors strongly believe that these characteristics may be a contributing factor for recurrences and patient discomfort. Other complications are reported in the literature to be a direct result of fixation of the implants, such as bleeding, nerve entrapment, hematoma, pain, discomfort, and testicular complications. To improve results by respecting the physiology and kinetics of the inguinal region, we felt that a new type of prosthesis should be designed that induces a more structured tissue ingrowth similar to the natural biologic components of the abdominal wall. This prosthetic device was specifically designed to be placed with no point fixation. This was achieved by

INTRODUCTION Favourable short-term results, with respect to less postoperative pain and earlier return to physical activity, have been demonstrated with laparoscopic totally extraperitoneal (TEP) hernia repair compared with open mesh repair. However, there is limited data regarding long-term results. PATIENTS AND METHODS The study cohort consisted of 275 consecutive patients undergoing TEP repair between 1996 and 2002. Patient demographics, details of surgery, postoperative complications, recurrence and chronic pain were collected from patient records and from a prospective database. All patients were seen at 6 weeks and then annually for 5 years following surgery. RESULTS A total of 430 repairs were performed in the 275 patients (median age, 56 years; range, 20–94 years; men, 97.5%). Bilateral repair was performed in 168 patients (61.1%) and recurrent hernia repair in 79 patients (28.7%). Two patients were converted to an open procedure. Five-year follow-up was achieved in 72% of patients. Eleven patients (4%) died during the follow-up period due to unrelated causes. Hernia recurrence rate at 5 years was 1.1% per patient (three repairs). Recurrences were noted at 7 months, 2 years and 4 years following surgery. Chronic groin pain was reported by 21 patients (7.6%), seven of whom required referral to the pain team. CONCLUSIONS TEP hernia repair is associated with a recurrence rate of 1% at 5 years in this series. Chronic groin symptoms are also acceptably few. This recurrence rate following TEP repair compares extremely favourably with open mesh repair, particularly as it includes a high proportion of recurrent repairs. As well as the proven early benefits, TEP repair can be considered a safe and durable procedure with excellent long-term results. PMID:20412671

Introduction: Although natural orifice transluminal endoscopic surgery promises truly scarless surgery, this has not progressed beyond the experimental setting and a few clinical cases in the field of ventral hernia repair. This is mainly because of the problem of sterilizing natural orifices, which prevents the use of any prosthetic material because of unacceptable risks of infection. Single-incision laparoscopic ventral hernia repair has gained more widespread acceptance by specialized hernia centers. Even so, there is a special subset of patients who are young and/or scar conscious and find any visible scar unacceptable. This study illustrates an innovative way of performing single-incision laparoscopic ventral hernia repair by a transverse suprapubic incision below the pubic hair/bikini line in 2 young male patients who had both umbilical and epigastric hernias as well as attenuated linea alba in the upper abdomen. Case Description: Both patients underwent successful laparoscopic repair, and both were highly satisfied with the procedure, which produced no visible scars on their abdomen. Discussion: Willingness to adopt new innovative procedures, such as single-incision laparoscopic surgery, has allowed modification of the incision site to produce invisible scars and hence become highly attractive to the young and scar-phobic segment of the population.

Background Surgery for inguinal hernia continues to evolve. The most recent development in the field of surgery for inguinal hernia is the emergence of laparoscopic inguinal hernia surgery (LIHS) which is challenging the gold standard Lichtenstein's tension free mesh repair. Our centre has the largest series of LIHS from any Armed Forces hospital. The aim of this study was to analyze the short and long term outcomes at our center since its inception. Methods Retrospective review of prospectively maintained data base of 501 LIHS done in 434 patients by a single surgeon between April 2008 and October 2013. Preoperative, intraoperative, postoperative and follow-up data was analyzed with emphasis on the recurrence rates and the incidence of inguinodynia. Results 402 (92.6%) patients had primary hernias and 367 (84.6%) patients had unilateral hernias. Of the 501 repairs, 453 (90.4 %) were done totally extraperitoneal approach and 48 (9.6 %) were done by the transabdominal preperitoneal approach. The mean operative time for unilateral and bilateral repairs was 40.9 ± 11.2 and 76.2 ± 15.0 minutes, respectively. The conversion rate to open surgery was 0.6%. The intraoperative, and early and late postoperative complication rates were 1.7%, 6.2% and 3%, respectively. The incidence of chronic groin pain was 0.7% and the recurrence rate was 1.6%. The median hospital stay was 1 day (1–5 days). Conclusion We, in this series of over 500 repairs have demonstrated that feasibility as well as safety of LIHS at our centre with good short and long term outcomes. PMID:26663957

High ligation of the inguinal hernia sac is standard practice for many pediatric surgeons in postpubertal adolescents. Most adult surgeons do not use this technique to repair indirect inguinal hernias because of concerns for higher recurrence rates compared with mesh repairs. Therefore, we examined long-term outcomes of adolescent high ligation hernia repair performed by pediatric surgeons. Telephone surveys were conducted on children over 12 years old at the time of repair, and patients and/or their parents were contacted 18 months postrepair. Patients were identified from two institutions between 1998 and 2010. The incidences of reoperation, recurrence, presence of bulge, chronic pain, or numbness were determined. A total of 210 patients (40.7% response rate) were available for phone interviews at 18.6 to 159.5 months postrepair. Mean age was 14.6 ± 1.8 (range: 12.0-19.0 years). Fourteen patients had pain (6.7%) and five had numbness (2.4%). There were four (1.9%) patients with a second operation, two of which confirmed a recurrent hernia. Three patients expressed concern about possible recurrence. Two report a bulge, but have not been evaluated. Pediatric hernia repair with high sac ligation appears effective in patients anatomically similar to adults with low recurrence rate and low incidence of chronic symptoms. These data suggest that prospective trials on the adequacy of high ligation in adults are warranted.

Background: Parastomal hernias (PSHs) are a frequent complication and remain a surgical challenge. We present a new option for single-port PSH repair with equilateral stoma relocation using preshaped, prosthetic 3-dimensional implants and flat mesh insertion in intraperitoneal onlay placement for additional augmentation of the abdominal wall. Methods: We describe our novel technique in detail and performed an analysis of prospectively collected data from patients who underwent single-port PSH repair, focusing on feasibility, conversions, and complications. Results: From September 2013 to January 2014, 9 patients with symptomatic PSHs were included. Two conversions to reduced-port laparoscopy using a second 3-mm trocar were required because of difficult adhesiolysis, dissection, and reduction of the hernia sac content. No major intra- or postoperative complications or reoperations were encountered. One patient incurred a peristomal wound healing defect that could be treated conservatively. Conclusion: We found that single-port PSH repair using preshaped, elastic 3-dimensional devices and additional flat mesh repair of the abdominal wall is feasible, safe, and beneficial, relating to optimal coverage of unstable stoma edges with wide overlap to all sides and simultaneous augmentation of the midline in the IPOM technique. The stoma relocation enables prolapse treatment and prevention. The features of a modular and rotatable multichannel port system offer benefits in clear dissection ongoing from a single port. Long-term follow-up data on an adequate number of patients are awaited to examine efficacy. PMID:25392655

Purpose. Operative efficiency improvements for laparoscopic ventral hernia repair (LVHR) have focused on reducing operative time while maintaining overall repair efficacy. Our objective was to evaluate procedure time and positioning accuracy of an inflatable mesh positioning device (Echo PS Positioning System), as compared to a standard transfascial suture technique, using a porcine model of simulated LVHR. Methods. The study population consisted of seventeen general surgeons (n = 17) that performed simulated LVHR on seventeen (n = 17) female Yorkshire pigs using two implantation techniques: (1) Ventralight ST Mesh + Echo PS Positioning System (Echo PS) and (2) Ventralight ST Mesh + transfascial sutures (TSs). Procedure time and mesh centering accuracy overtop of a simulated surgical defect were evaluated. Results. Echo PS demonstrated a 38.9% reduction in the overall procedure time, as compared to TS. During mesh preparation and positioning, Echo PS demonstrated a 60.5% reduction in procedure time (P < 0.0001). Although a trend toward improved centering accuracy was observed for Echo PS (16.2%), this was not significantly different than TS. Conclusions. Echo PS demonstrated a significant reduction in overall simulated LVHR procedure time, particularly during mesh preparation/positioning. These operative time savings may translate into reduced operating room costs and improved surgeon/operating room efficiency. PMID:23762628

Intraperitoneal (IP) ventral hernia repair has been proposed with the advantages of reducing dissection, operative time, and postoperative pain. The IP position of the mesh is suspected of increasing the risk of visceral adhesion and inducing complications. To overcome these drawbacks, a mesh protected on one side by a hydrophilic resorbable film (Parietex Composite) has been validated. Using a previously described ultrasound procedure, the purpose of this study was to compare the rate of visceral adhesion after intraperitoneal placement of a polyester mesh versus this protected mesh. Fifty-one patients who received a Parietex Composite mesh were prospectively compared to a retrospective series of 22 consecutive asymptomatic patients who received a Mersilene mesh. To objectively assess visceral adhesion toward the abdominal wall, an ultrasound (US) specific examination was firstly validated and secondly used to evaluate the adhesion incidence in both groups. Both groups were equivalent in terms of inclusion criteria and body mass index (BMI). Pre-operative US versus perioperative macroscopical findings determined the following parameters: sensitivity 83%, accuracy 78%, negative predictive value 81%. Using this procedure, 77% of the patients exhibited visceral adhesion to the mesh in the Mersilene group, against 18% in the Parietex Composite group (P<0.001, chi-square). US examination represents a suitable tool to evaluate postoperative adhesions to the abdominal wall. Using this procedure, a significant reduction of visceral adhesion in the Parietex Composite group was shown.

Intraperitoneal placement of prosthetic mesh causes adhesion formation after laparoscopic incisional hernia repair. A prosthesis that prevents or reduces adhesion formation is desirable. In this study, 21 pigs were randomized to receive laparoscopic placement of plain polypropylene mesh (PPM), expanded polytetrafluoroethylene (ePTFE), or polypropylene coated on one side with a bioresorbable adhesion barrier (PPM/HA/CMC). The animals were sacrificed after 28 days and evaluated for adhesion formation. Mean area of adhesion formation was 14% (SD+/-15) in the PPM/HA/CMC group, 40% (SD+/-17) in the PPM group, and 41% (SD+/-39) in the ePTFE group. The difference between PPM/HA/CMC and PPM was significant ( P=0.013). A new visceral layer of mesothelium was present in seven out of seven PPM/HA/CMC cases, six out of seven PPM cases, and two out of seven ePTFE cases. Thus, laparoscopic placement of PPM/HA/CMC reduces adhesion formation compared to other mesh types used for laparoscopic ventral hernia repairs.

Introduction Obturator hernia (OH) is a rare condition and difficult to diagnose. While they account for as few as 0.073% of all hernias, mortality can be as high as 70%. The typical clinical presentation for OH is small bowel obstruction. Computed tomography is the diagnostic tool of choice. Surgical repair is mandatory in virtually all cases of OH and traditionally consists of performing an exploratory laparotomy. Presentation of case A 90-year-old female was admitted to our surgical service with signs of small bowel obstruction and a CT scan revealing incarcerated fatty tissue and small bowel within a left OH. Discussion The role of laparoscopic surgery in the management of OH has been limited to elective repairs; most reports detail that the OH was found serendipitously during laparoscopic inguinal hernia operations or other pelvic procedures. A few reports describe the use of laparoscopy to treat OH associated with bowel obstruction in an emergency setting using a TAPP approach. A strict TEP hernia repair is not indicated for all patients with OH, and should rarely be performed in emergency situations given its limitation to assess or resect bowel if necessary. In selected cases, a formal exploratory laparoscopy that is negative for compromised bowel can be safely followed by a TEP repair using the same umbilical access as shown in our patient. Conclusion A 90-year-old female with a small bowel obstruction related to an incarcerated OH was treated effectively with an extraperitoneal laparoscopic approach. PMID:22096757

Introduction The aim of this study is to evaluate sexual functions which are affected by inguinal hernias and may change after hernia repair surgery. Material and methods A total of 47 patients who underwent Lichtenstein tension-free anterior repair and inguinal hernia surgery were evaluated in terms of erectile function, intercourse function, sexual desire, overall satisfaction and orgasm satisfaction using the International Index of Erectile function questionnaire (IIEF) scoring system before surgery and in the first and sixth months after surgery. Parameters evaluated with the IIEF score before the surgery and in the first and sixth months after surgery were compared statistically using the Wilcoxon test. Results The average age of patients was 46.2 ±11.2 years (range: 22–67). It was determined that all scores, apart from sexual desire (p = 0.08), significantly increased in the postoperative first and sixth months compared to the preoperative period. It was measured that the preoperative sexual desire score increased significantly in the postoperative sixth month (p <0.001). A significant score was also detected when all scores in the postoperative sixth month were compared to the postoperative first month. Conclusions Inguinal hernia surgery positively affects sexual functions compared to the preoperative period. The improvement in sexual parameters in addition to the benefits of hernia removal and presence of no significant postoperative complications indicates that this surgery is useful and safe.

Prosthetic mesh infection after open or laparoscopic hernia repair is a rare complication. Superficial wound infection can be resolved by treatment with a combination of antibiotics and wound drainage, whereas deep-seated mesh infection, which can lead to chronic groin sepsis, usually requires removal of the mesh. A 56-year-old Japanese man was admitted to our hospital for the treatment of deep-seated mesh infection. The patient had undergone inguinal hernia repair at another hospital 18 months earlier. The operation was prosthetic mesh repair via an anterior approach. The patient developed deep-seated mesh infection despite conservative treatment for infection, such as abscess drainage and antibiotic therapy. Since the patient eventually developed chronic groin sepsis, he was referred to our hospital, and infected mesh was removed successfully by laparoscopic surgery via a totally extraperitoneal approach. The laparoscopic approach provides several advantages, including less postoperative pain, a shorter hospital stay, and earlier rehabilitation. Furthermore, seeding of the abdominal cavity with pus never occurs with this approach unlike the laparoscopic transabdominal preperitoneal approach.

Background: Adhesions induced by biomaterials experimentally implanted in the abdominal cavity are basically studied by primary repair of different abdominal wall defects or by the correction of incisional hernias previously performed with no precise definition of the most appropriate model. Aim: To describe the adhesions which occur after the development of incisional hernias, before the prosthesis implantation, in an experimental model to study the changes induced by different meshes. Methods: Incisional hernias were performed in 10 rats with hernia orifices of standardized dimensions, obtained by the median incision of the abdominal wall and eversion of the defect edges. Ten days after the procedure adhesions of abdominal structures were found when hernias were repaired with different meshes. Results: The results showed hernia sac well defined in all rats ten days after the initial procedure. Adhesions of the greater omentum occurred in five animals of which two also showed adhesions of small bowel loops besides the omentum, and another two showed liver adhesions as well as the greater omentum, numbers with statistical significance by Student's t test (p<0.05). Conclusion: Although it reproduces the real clinical situation, the choice of experimental model of incisional hernia repair previously induced implies important adhesions, with possible repercussions in the evaluation of the second operation, when different implants of synthetic materials are used.

Over 10 years one senior consultant surgeon performed 114 standard plication darn herniorraphies on 92 patients with primary inguinal hernias. These patients were contacted and were reviewed if there was any suspicion of recurrence. Four recurrences were detected, giving an overall recurrence rate of about 3.5%. According to actuarial life-table analysis the risks of recurrence at 1 year, 5 years and 10 years were 0.94%, 3.02% and 9%. This level of recurrence is unacceptable in modern practice and, as a result of the audit, the surgeon changed his technique of primary inguinal hernia repair. PMID:10325875

A 77 year old woman who presented with an incarcerated hernia of Morgagni was successfully treated without complications. A Medline search (1996 to date) along with cross referencing was done to quantify the number of acute presentations in adults compared to children. Different investigating modalities—for example, lateral chest and abdominal radiography, contrast studies or, in difficult cases, computed tomography or magnetic resonance imaging—can be used to diagnose hernia of Morgagni. The favoured method of repair—laparotomy or laparoscopy—is also discussed. A total of 47 case reports on children and 93 case reports on adults were found. Fourteen percent of children (seven out of 47) presented acutely compared with 12% of adults (12 out of 93). Repair at laparotomy was the method of choice but if uncertain, laparoscopy would be a useful diagnostic tool before attempted repair. Laparoscopic repair was favoured in adults especially in non-acute cases. PMID:15640427

The widespread use of meshes for hiatal hernia repair has emerged in the era of laparoscopic surgery, although sporadic cases of mesh augmentation of traumatic diaphragmatic rupture have been reported. The indications for biologic meshes in diaphragmatic repair are ill defined. This systematic review aims to investigate the available evidence on the role of biologic meshes in diaphragmatic rupture and hiatal hernia repair. Limited data from sporadic case reports and case series have demonstrated that repair of traumatic diaphragmatic rupture with biologic mesh is safe technique in both the acute or chronic setting. High level evidence demonstrates short-term benefits of biologic mesh augmentation in hiatal hernia repair over primary repair, although adequate long-term data are not currently available. Long-term follow-up data suggest no benefit of hiatal hernia repair using porcine small intestine submucosa over suture repair. The effectiveness of different biologic mesh materials on hernia recurrence requires further investigation.

Hernias are generally repaired using synthetic prostheses. Infection may already be present or develop during implantation. Based on the increasing resistance to antibiotics, and the well-known antimicrobial properties of silver (Ag), the possibility of coating hernia prostheses with a nanostructured layer containing Ag was explored. Prostheses (Clear Mesh Composite [CMC]) made up of two polypropylene layers (macroporous light mesh and thin transparent film) were tested with human mesothelial cells from omentum biopsies. Mesotheliocytes modulate abdominal wall healing producing cytokines, growth factors, and adhesion molecules. Evaluating the growth of these cells on CMC or film alone showed that cell numbers on CMC increased over time, and were higher than those on film alone. Vimentin immunostaining confirmed the cells to be mesotheliocytes. Subsequently, the biocompatibility of mesh layer, coated or not with a thin layer of Ag/SiO2 -nanoclusters, was analyzed, showing no difference in absence or presence of Ag/SiO2 . Differently, TGF-β2 production, involved in tissue repair and fibrosis, increased in the presence of Ag/SiO2 . Moreover, Ag/SiO2 -coated mesh showed antibacterial properties. In conclusion, the mesh layer coated with Ag/SiO2 afforded cell growth, and showed antibacterial activity. Coating only the mesh layer did not decrease film transparency, and did not favor the formation of adhesions on the visceral side. © 2016 Wiley Periodicals, Inc.

Background and Objectives: Treatment of gastroesophageal reflux disease (GERD) with hiatal hernia in obese patients has proven difficult, as studies demonstrate poor symptom control and high failure rates in this patient population. Recent data have shown that incorporating weight loss procedures into the treatment of reflux may improve overall outcomes. Methods: We retrospectively reviewed 28 obese and morbidly obese patients who presented from December 2007 through July 2013 with large or recurrent type 3 or 4 paraesophageal hernia. All of the patients underwent combined paraesophageal hernia repair and partial longitudinal gastrectomy. Charts were retrospectively reviewed, and the patients were contacted to determine symptomatic relief. Results: Mean preoperative body mass index was 38.1 ± 4.9 kg/m2. Anatomic failure of prior fundoplication occurred in 7 patients (25%). The remaining 21 had primary paraesophageal hernia, 3 of which were type 4. Postoperative complications included pulmonary embolism (n = 1), pulmonary decompensation (n = 2), and wound infection (n = 1). Mean hospital stay was 5 ± 3 days. Upper gastrointestinal esophagogram was performed in 21 patients with no immediate recurrence or staple line dehiscence. Mean excess weight loss was 44 ± 25%. All of the patients surveyed experienced near to total resolution of their preoperative symptoms within the first month. At 1 year, symptom scores decreased significantly. At 27 months, however, there was a mild increase in the scores. Return of severe symptoms occurred in 2 patients, both of whom underwent conversion to gastric bypass. Conclusions: Combined laparoscopic paraesophageal hernia repair with longitudinal partial gastrectomy offers a safe, feasible approach to the management of large or recurrent paraesophageal hernia in well-selected obese and morbidly obese patients. Short-term results were promising; however, intermediate results showed increasing rates of reflux symptoms that required

Abstract To investigate the efficacy, key technical points, and complication management of the transabdominal preperitoneal (TAPP) approach for incarcerated inguinal hernia repair. Seventy-three patients with incarcerated inguinal hernias underwent TAPP surgery in our department between Jan 2010 and Dec 2015. A retrospective review was performed by analyzing the perioperative data from these patients. The operation was successfully completed in all 73 patients. Operation time was 54.0 ± 18.8 minutes (range, 35–100 minutes). Length of stay was 3.9 ± 1.1 days (range, 3–9 days). There was 1 case of incisional infection, 32 cases of seroma, and 3 cases of postoperative pain during follow-up. All patients recovered after the appropriate treatment. No recurrence or fistula was observed. The TAPP approach represents a safe and effective technique for incarcerated inguinal hernia repair because of its potential in assessment of hernia content and decreasing incisional infection rate. However, it requires experienced surgeons to ensure safety with special attention paid to the key technical points as well as complication management. PMID:28033260

INTRODUCTION We aimed to report the outcomes of inguinal hernia repair performed at Tan Tock Seng Hospital and compare them with those performed at dedicated hernia centres. METHODS We retrospectively analysed the medical records and telephone interviews of 520 patients who underwent inguinal hernia repair in 2010. RESULTS The majority of the patients were male (498 [95.8%] men vs. 22 [4.2%] women). The mean age was 59.9 ± 15.7 years. Most patients (n = 445, 85.6%) had unilateral hernias (25.8% direct, 64.3% indirect, 9.9% pantaloon). The overall recurrence rate was 3.8%, with a mean time to recurrence of 12.0 ± 8.6 months. Risk factors for recurrence included contaminated wounds (odds ratio [OR] 50.325; p = 0.004), female gender (OR 8.757; p = 0.003) and pantaloon hernias (OR 5.059; p = 0.013). Complication rates were as follows: chronic pain syndrome (1.2%), hypoaesthesia (5.2%), wound dehiscence (0.4%), infection (0.6%), haematoma/seroma (4.8%), urinary retention (1.3%) and intraoperative visceral injury (0.6%). Most procedures were open repairs (67.7%), and laparoscopic repair constituted 32.3% of all the inguinal hernia repairs. Open repairs resulted in longer operating times than laparoscopic repairs (86.6 mins vs. 71.6 mins; p < 0.001), longer hospital stays (2.7 days vs. 0.7 days; p = 0.020) and a higher incidence of post-repair hypoaesthesia (6.8% vs. 1.8%; p = 0.018). However, there were no significant differences in recurrence or other complications between open and laparoscopic repair. CONCLUSION A general hospital with strict protocols and teaching methodologies can achieve inguinal hernia repair outcomes comparable to those of dedicated hernia centres. PMID:24763834
Inguinal hernia repair (IHR) with prosthetic mesh implantation is the most common procedure in general surgery, and may be performed using either an open or laparoscopic approach. This paper provides an overview of contemporary tension-free IHR techniques and materials, and illustrates the expected postoperative imaging findings and iatrogenic injuries. Emphasis is placed on multidetector CT, which represents the ideal modality to comprehensively visualize the operated groin region and deeper intra-abdominal structures. CT consistently depicts seroma, mesh infections, hemorrhages, bowel complications and urinary bladder injuries, and thus generally provides a consistent basis for therapeutic choice. Since radiologists are increasingly requested to investigate suspected iatrogenic complications, this paper aims to provide an increased familiarity with early CT studies after IHR, including complications and normal postoperative appearances such as focal pseudolesions, in order to avoid misinterpretation and inappropriate management.

The aim of this study was to compare the results of the surgery of inguinal hernias using flat polypropylene mesh and three-dimensional prolene (PHS) mesh. The study included two groups of 40 male patients, aged 18-50 years, with the diagnosis of inguinal hernia. One group was operated with a flat polypropylene mesh, while the second group was operated with three-dimensional prolene (PHS) mesh. The study has shown that the operation with three-dimensional prolene mesh lasted 15 minutes longer and that the patients had stronger inflammatory response. Statistically, there was no significant difference in post-operative pain intensity, post-operative use of analgesics, length of hospitalization, return to daily activities, early and late post-operative complications. No recurrence was registered in any of the groups. The analysis of results indicates that there is no difference in treatment of inguinal hernia with flat polypropylene and three-dimensional prolene (PHS) mesh.

The widespread use of meshes for hiatal hernia repair has emerged in the era of laparoscopic surgery, although sporadic cases of mesh augmentation of traumatic diaphragmatic rupture have been reported. The indications for biologic meshes in diaphragmatic repair are ill defined. This systematic review aims to investigate the available evidence on the role of biologic meshes in diaphragmatic rupture and hiatal hernia repair. Limited data from sporadic case reports and case series have demonstrated that repair of traumatic diaphragmatic rupture with biologic mesh is safe technique in both the acute or chronic setting. High level evidence demonstrates short-term benefits of biologic mesh augmentation in hiatal hernia repair over primary repair, although adequate long-term data are not currently available. Long-term follow-up data suggest no benefit of hiatal hernia repair using porcine small intestine submucosa over suture repair. The effectiveness of different biologic mesh materials on hernia recurrence requires further investigation. PMID:26539439

Since Ramirez et al. presented the first case of component separation for abdominal wall hernias in 1990, it has undergone multiple modifications. This technique, which has been mainly used for large hernias where primary closure of the abdominal wall is not feasible, or for staged management of patients with open abdomens, results in multiple wound complications. In 2007, Rosen et al. reported on the laparoscopic approach to component separation that is associated with less subcutaneous dissection and the consequent advantage of a decreased risk of flap necrosis and wound infection. Here we discuss our totally laparoscopic approach to abdominal wall reconstruction. A minimally invasive abdominal wall reconstruction consists of a bilateral component separation, an intra-abdominal adhesiolysis, primary approximation of rectus muscles, and placement of an intraperitoneal mesh for reinforcing the repair, all performed laparoscopically. Patient-selection criteria, detailed operative technique, tips in preventing and managing the potential pitfalls, and postoperative care are discussed.

Covering a large hiatal hernia with a mesh has become a basic procedure in the last few years. However, mesh implants are associated with high complication rates (esophageal erosion, perforation, fistula, etc.). We propose using a synthetic resorbable mesh supported with an omental flap as a possible solution to this problem. A 54-year-old female patient with a large hiatal defect (9 cm) was laparoscopically implanted with a synthetic resorbable mesh supported with an omental flap. The surgical procedure was successful and the patient was discharged on postoperative day 2. On a follow-up examination 6 months after surgery, she remained free of relapse or complication signs. Supporting an implanted resorbable mesh with an omental flap may be a solution to the problems posed by large esophageal hiatus defects. However, more studies based on larger patient samples and longer follow-up periods are necessary. PMID:25216419

Repair of an indirect inguinal hernia is one of the most common operations performed around the world by pediatric surgeons. Until the last 15 years, most inguinal hernia repairs were performed using an inguinal crease incision and extraperitoneal ligation of the patent processes vaginalis. However, since 2000, the laparoscopic approach has gained popularity and there have been increasing descriptions about various techniques for laparoscopic hernia (LH) repair. At our institution, we have transitioned the majority of inguinal hernia repairs to the laparoscopic approach. In this article, we will describe the technique that is utilized at Children’s Mercy Hospital in Kansas City, Missouri (USA) and express our thoughts on the current debate regarding laparoscopic versus open inguinal hernia repair in infants and children.

The management of incisional hernia following radical cystectomy (RC) and neobladder diversion poses a special challenge. Mesh erosion into the neobladder is a potential complication of hernia repair in this setting. We describe our experience and steps to avoid this complication. Three patients developed incisional hernias following RC involving the neobladder. The incisional hernias were repaired by the same surgeon. A systematic dissection and repair of the hernias with an onlay dual-layer mesh (made of polyglactin and polypropylene) was carried out. The critical steps were placing the polyglactin side of the mesh deeper and positioning of an omental flap anterior to the neobladder. The omental flap adds a protective layer that prevents adhesions between the neobladder and abdominal wall, and prevents erosion of the mesh into the fragile neobladder wall. All of these patients had received two cycles of neoadjuvant chemotherapy prior to RC. The time duration from RC to the repair of hernia was 7, 42, and 54 months. No intraoperative injury to the neobladder or other complication was noted during hernia repair. The patients were followed after hernia repair for 20, 22, and 42 months with no recurrence, mesh erosion, or other complications. Careful understanding and attention to details of the technique can minimize the risk of complications, especially incisional hernia recurrence, injury to the neobladder, and erosion of mesh into the neobladder wall.

Background: The most frequent wound complication following repair of large incisional hernias is seroma formation, especially when the use of a mesh onlay requires extensive subcutaneous undermining. Treatment options for postoperative seromas include observation for spontaneous resolution, percutaneous aspiration, closed suction drainage, abdominal binders, and sclerosant. Methods: A novel technique for treating persistent postoperative seromas is presented herein. This technique involves a 3-puncture minimally invasive approach that can be performed in an outpatient setting. Evacuation of serous fluid and fibrinous debris is followed by argon beam scarification of the seroma cavity lining. Talc slurry is then introduced into the cavity. Three patients have been treated with this technique. Results: All 3 patients had successful ablation of seromas that had persisted despite standard treatment modalities. Conclusion: A minimally invasive approach is a reasonable and safe alternative for treating persistent postoperative seromas. PMID:11548834

Parastomal hernias represent a clinically significant problem for many patients after radical cystectomy and ileal conduit diversion. The prevalence may be as high as 60% and in some series, up to 30% of patients require surgical intervention due to the complications of pain, poor fit of an ostomy appliance, leakage, urinary obstruction, and bowel obstruction or strangulation. Due to the potential morbidity associated with PH repair, there have been efforts to prevent PH development at the time of the index surgery. Four randomized trials of prophylactic mesh placement at the time of colostomy and ileostomy stoma formation have demonstrated significant reductions in PH rates with acceptably low complication rates. In this review, we describe the clinical and radiographic definitions of PH, the clinical impact and risk factors behind its development, and the rationale behind prophylactic mesh placement for patients undergoing ileal conduit urinary diversion. Additionally, we report our experience with prophylactic mesh placed at radical cystectomy at our institution. PMID:26757903
Introduction A superior lumbar hernia, which is also known as a Grynfeltt hernia, is a rare abdominal wall defect that can be primary or secondary to trauma or orthopedic surgery. The anatomic location of a lumbar hernia makes diagnosis and repair challenging. We successfully repaired a lumbar hernia using a single-incision laparoscopic total extraperitoneal approach. To the best of our knowledge, this is the first report of the use of this surgical technique in the treatment of a primary Grynfeltt hernia. Case presentation A 76-year-old Taiwanese man presented to our hospital with a left lower bulging mass noted for over three months. Abdominal computed tomography revealed a left Grynfeltt hernia. We performed a single-incision laparoscopic total extraperitoneal repair. Our patient was discharged uneventfully on the fourth day after the operation. There was no evidence of recurrence after six months of follow-up. Conclusion A laparoscopic total extraperitoneal repair for a lumbar hernia provides an excellent operative view and minimal invasiveness. The single-incision technique also provides better cosmetic outcomes. Our experience suggests that the single-incision laparoscopic total extraperitoneal approach may be a feasible and safe alterative to conventional approaches in lumbar hernia repair. PMID:24428946
Background Incisional hernia is the most frequently seen long term complication after laparotomy causing much morbidity and even mortality. The overall incidence remains 11-20%, despite studies attempting to optimize closing techniques. Two patient groups, patients with abdominal aortic aneurysm and obese patients, have a risk for incisional hernia after laparotomy of more than 30%. These patients might benefit from mesh augmented midline closure as a means to reduce incisional hernia incidence. Methods/design The PRImary Mesh Closure of Abdominal Midline Wound (PRIMA) trial is a double-blinded international multicenter randomized controlled trial comparing running slowly absorbable suture closure with the same closure augmented with a sublay or onlay mesh. Primary endpoint will be incisional hernia incidence 2 years postoperatively. Secondary outcomes will be postoperative complications, pain, quality of life and cost effectiveness. A total of 460 patients will be included in three arms of the study and randomized between running suture closure, onlay mesh closure or sublay mesh closure. Follow-up will be at 1, 3, 12 and 24 months with ultrasound imaging performed at 6 and 24 months to objectify the presence of incisional hernia. Patients, investigators and radiologists will be blinded throughout the whole follow up. Disccusion The use of prosthetic mesh has proven effective and safe in incisional hernia surgery however its use in a prophylactic manner has yet to be properly investigated. The PRIMA trial will provide level 1b evidence whether mesh augmented midline abdominal closure reduces incisional hernia incidence in high risk groups.

This study examined and compared the effectiveness of woven vicryl (polyglactin 910) mesh and lyophilized cadaver dura (Lyodura) for the repair of spinal dural defects. A woven vicryl mesh was used to repair spinal dural defects in 16 mongrel dogs. As an internal control, all animals had a separate dural incision that was closed with 9-0 vicryl suture. Animals were killed, and results were evaluated at 4, 8, 12, and 24 weeks. The repair of dural defects was achieved in all animals, and there were no cases of pseudo-meningocele formation, cerebrospinal fluid leakage, or postoperative infection. The vicryl mesh served as a latticework for formation of a neodural membrane. Inflammatory or reactive response to vicryl mesh was minimal, and no adhesion to underlying neural structures was noted. The neodural membrane formed in the animals in which lyophilized dura was employed was usually thicker than those in which vicryl mesh was used and was associated with thick arachnoid-neural adhesions in two of eight animals. We believe vicryl mesh is a suitable dural substitute and offers promise for use in clinical situations.

Acute symptomatic groin hernias with potential or definite ischemia represent a special group of all the groin hernias. The method of choice to treat these hernias has to fulfill the following criteria: 1. Easy reduction of the hernia sac and its contents without causing damage. 2. Good exposure and easy access for possible resection. 3. Safe hernia repair through the same access. According to our experience with 44 incarcerated and strangulated groin hernias operated between 1993 and 1997 and after a literature review, we took the following procedure as our routine: Posterior approach and mesh repair. We do not use a meshgraft only in the presence of colonic necrosis or peritonitis.

The less traumatic use of surgical adhesives rather than sutures for mesh fixation in hernia repair has started to gain popularity because they induce less host tissue damage and provoke less postoperative pain. This study examines the host tissue response to a new cyanoacrylate (CA) adhesive (n-octyl, OCA). Partial defects (3 × 5 cm) created in the rabbit anterior abdominal wall were repaired by mesh fixation using OCA, Glubran2(®)(n-butyl-CA), Ifabond(®)(n-hexyl-CA) or sutures. Samples were obtained at 14/90 days for morphology, collagens qRT-PCR/immunofluorescence and biomechanical studies. All meshes were successfully fixed. Seroma was detected mainly in the Glubran group at 14 days. Meshes fixed using all methods showed good host tissue incorporation. No signs of degradation of any of the adhesives were observed. At 14 days, collagen 1 and 3 mRNA expression levels were greater in the suture and OCA groups, and lower in Ifabond, with levels varying significantly in the latter group with respect to the others. By 90 days, expression levels had fallen in all groups, except for collagen 3 mRNA in Ifabond. Collagen I and III protein expression was marked in the suture and OCA groups at 90 days, but lower in Ifabond at both time points. Tensile strengths were similar across groups. Our findings indicate the similar behavior of the adhesives to sutures in terms of good tissue incorporation of the meshes and optimal repair zone strength. The lower seroma rate and similar collagenization to controls induced by OCA suggests its improved behavior over the other two glues. This article deals with a preclinical study to examine different aspects of the repair process in the host of three alkyl cyanoacrylates (n-butyl (GLUBRAN 2), n-hexyl (IFABOND), and n-octyl cyanoacrylate (EVOBOND)) compared to sutures (control), in the fixation of surgical meshes for hernia repair. It goes into detail about collagen deposition in the repair zone at short and medium term. The

Object In MRI, implants and devices can be delineated via susceptibility artefacts. To discriminate susceptibility voids from proton-free structures, different positive contrast techniques were implemented. The purpose of this study was to evaluate a pulse sequence-based positive contrast technique (PCSI) and a post-processing susceptibility gradient mapping algorithm (SGM) for visualization of iron loaded mesh implants in patients. Material and Methods Five patients with iron-loaded MR-visible inguinal hernia mesh implants were examined at 1.5 Tesla. A gradient echo sequence (GRE; parameters: TR: 8.3ms; TE: 4.3ms; NSA:2; FA:20°; FOV:350mm²) and a PCSI sequence (parameters: TR: 25ms; TE: 4.6ms; NSA:4; FA:20°; FOV:350mm²) with on-resonant proton suppression were performed. SGM maps were calculated using two algorithms. Image quality and mesh delineation were independently evaluated by three radiologists. Results On GRE, the iron-loaded meshes generated distinct susceptibility-induced signal voids. PCSI exhibited susceptibility differences including the meshes as hyperintense signals. SGM exhibited susceptibility differences with positive contrast. Visually, the different algorithms presented no significant differences. Overall, the diagnostic value was rated best in GRE whereas PCSI and SGM were barely “sufficient”. Conclusion Both “positive contrast” techniques depicted implanted meshes with hyperintense signal. SGM comes without additional acquisition time and can therefore be utilized in every patient. PMID:27192201

Pneumothorax was identified as a complication of endoscopic hernia repair in two patients with insufflation pressures of 15 mmHg and operating times exceeding 2 h. These patients also showed intraoperative perturbations in both oxygen saturation and end-tidal CO2 production. A prospective study was undertaken to determine whether similar complications would arise if preperitoneal insufflation pressures were limited to 10 mmHg. Postoperative chest x-rays were obtained on all patients to check for pneumothoraces, even clinically occult ones. Fifty patients were studied, with average operating times of 67 min. No patient demonstrated any hemodynamic or ventilatory changes, and none had any evidence of pneumothorax on x-ray. We conclude that these complications were not present when insufflation pressure was maintained at 10 mmHg and that routine x-ray is not warranted. Larger randomized trials of insufflation pressures are needed.

ABSTRACT The use of meshes has become the first option for the treatment of soft tissue disorders as hernias and stress urinary incontinence and widely used in vaginal prolapse's treatment. However, complications related to mesh issues cannot be neglected. Various strategies have been used to improve tissue integration of prosthetic meshes and reduce related complications. The aim of this review is to present the state of art of mesh innovations, presenting the whole arsenal which has been studied worldwide since composite meshes, coated meshes, collagen's derived meshes and tissue engineered prostheses, with focus on its biocompatibility and technical innovations, especially for vaginal prolapse surgery.

Repair of giant inguino-scrotal hernia (GISH) in male infants is a difficult operation, even in experienced hands. It requires an immaculate technique to avoid known complications such as tearing of the sac, injury to delicate testicular vessels and dividing of vas deferens. Moreover, a recurrence rate of 9% is noted in a number of reports. This article describes a new surgical maneuver to simplify the procedure. All GISH repaired by the author, over a 5-year period (October 2001-September 2006), were reviewed retrospectively. In total, 89 infants with 106 GISH underwent uni- or bilateral herniotomies. A standard inguinal incision is made and Scarpa's fascia is sharply opened; the external inguinal ring and the cord is identified. By gentle manipulation and blunt dissection, the spermatic cord together with the testis is exteriorized. The assistant applies gentle traction to the cord, which allows for easy identification of the inguinal sac and its subsequent separation from vas and vessels. Testis is replaced in the scrotum, hernial sac suture ligated at its base and the wound closed in layers. All cases were managed with the above approach. The average length of the procedure was 11 min for unilateral and 19 min for bilateral cases. Except for minimal scrotal swelling post-operatively, no other surgery-related complications were noted during or immediately after the operation. Testicular atrophy or iatrogenic undescended testes were not encountered in the follow-up period. Ipsilateral recurrent hernia was noted in one infant after 6 months which required re-operation with the same technique. In cases of GISH; dislocating the testis into the wound and applying a gentle stretch on the cord allows for a safe dissection of the hernial sac and subsequent herniotomy. This maneuver converts a difficult procedure into a relatively simple one.

Background The effect of hospital specialization on the risk of hernia recurrence after inguinal hernia repair is not well described. Methods We studied Ontario residents who had primary elective inguinal hernia repair at an Ontario hospital between 1993 and 2007 using population-based, administrative health data. We compared patients from a large hernia specialty hospital (Shouldice Hospital) with those from general hospitals to determine the risk of recurrence. Results We studied 235 192 patients, 27.7% of whom had surgery at Shouldice hospital. The age-standardized proportion of patients who had a recurrence ranged from 5.21% (95% confidence interval [CI] 4.94%–5.49%) among patients who had surgery at the lowest volume general hospitals to 4.79% (95% CI 4.54%–5.04%) who had surgery at the highest volume general hospitals. In contrast, patients who had surgery at the Shouldice Hospital had an age-standardized recurrence risk of 1.15% (95% CI 1.05%–1.25%). Compared with patients who had surgery at the lowest volume hospitals, hernia recurrence among those treated at the Shouldice Hospital was significantly lower after adjustment for the effects of age, sex, comorbidity and income level (adjusted hazard ratio 0.21, 95% CI 0.19–0.23, p < 0.001). Conclusion Inguinal hernia repair at Shouldice Hospital was associated with a significantly lower risk of subsequent surgery for recurrence than repair at a general hospital. While specialty hospitals may have better outcomes for treatment of common surgical conditions than general hospitals, these benefits must be weighed against potential negative impacts on clinical care and the financial sustainability of general hospitals.

We present a case of congenital diaphragmatic hernia that was successfully treated with spi-ral tacks using thoracoscopy. A newborn female was diagnosed with a diaphragmatic hernia at 20 weeks of gestation. The defect was surgically repaired by thoracoscopy and primary closure. On postoperative day 25, she developed respiratory distress. Chest x-ray showed a recurrence and was taken to the OR for surgical repair with spiral tacks. PMID:26290813

Introduction The laparoscopic approach to repairing ventral and incisional hernias has gained increasing popularity worldwide. We reviewed the experience of laparoscopic ventral hernia repair at a district general hospital in the UK with particular reference to patients with massive defects (diameter ≥15cm) and the morbidly obese. Methods A total of 144 patients underwent laparoscopic ventral (incisional or umbilical/paraumbilical) hernia repair between April 2007 and September 2012. Results The prevalence of conversion to open surgery was 2.8%. The prevalence of postoperative complications was 3.5%. Median postoperative follow-up was 30.2 months. A total of 5.6% cases suffered late complications and 2.8% developed recurrence. Thirty-four patients underwent repair of defects ≥10cm in diameter with a prevalence of recurrence of 5.6%. Sixteen patients underwent repair of ‘massive’ incisional hernia (diameter ≥15cm) with a prevalence of recurrence of 12.5%. Sixteen patients with a body mass index (BMI) ≥40kg/m2 (range, 40–61kg/m2) underwent laparoscopic repair with a prevalence of recurrence of 6.3% (p>0.05 vs BMI <40kg/m2). Conclusions Laparoscopic ventral hernia repair can be carried out safely with a low prevalence of recurrence. It may have advantages in morbidly obese patients in whom open repair would represent a significant undertaking. Laparoscopic ventral hernia repair may be used in cases of large and massive hernias, in which the risk of recurrence increases but is comparable with open repair and associated with low morbidity.

Objective To determine whether any common maternal-fetal variable has prenatal predictive value of prosthetic repair in congenital diaphragmatic hernia. Methods This was a 5-year single-center retrospective review of fetal congenital diaphragmatic hernia referrals. Multiple prenatal variables were correlated with the need for a prosthetic repair. Statistical analyses were by Fisher's exact and Mann-Whitney U-tests, as appropriate (p < 0.05). Results Fetal liver position was a predictor of prosthetic repair. The presence or absence of liver herniation was correlated with prosthetic repair rates of 83.3 and 23.1%, respectively (p < 0.001). All patients with moderate/severe liver herniation required a prosthetic patch. Conclusion Liver herniation has prenatal predictive value for the need for prosthetic repair in congenital diaphragmatic hernia. This finding should be valuable during prenatal counseling for clinical trials of engineered diaphragmatic repair. PMID:18417990

Bochdalek hernia is a rare pathology. The preoperative diagnosis is difficult, and few reports are available regarding its treatment. Herein we report the case of a 25-year-old woman referred for symptoms of dyspepsia, dysphagia, and thoracic pain exacerbated by pregnancy. Preoperative radiography, EGD, and CT scan revealed a paraesophageal hiatal hernia. Laparoscopic exploration showed the complete thoracic migration of the stomach through a left posterolateral diaphragmatic foramen. The diagnosis of a Bochdalek hernia was then made. The diaphragmatic defect was repaired without inserting a prosthesis, using five separate non-reabsorbable stitches (Rieder technique). The procedure was completed with a Nissen-Rossetti fundoplication. The duration of the procedure was 150 min. Hospital stay was 12 days. There were no complications. Postoperative Gastrografin radiography of the esophagus and stomach showed a normal-shaped fundoplication and confirmed the subdiaphragmatic location of the stomach. We conclude that the laparoscopic approach represents the gold standard for the diagnosis and treatment of Bochdalek hernia and any associated complications.

Background Laparoscopic hernia repair is used widely for the repair of incisional hernias. Few case studies have focussed on purely ‘incisional’ hernias. This multicentre series represents a collaborative effort and employed statistical analyses to provide insight into the factors predisposing to recurrence of incisional hernia after laparoscopic repair. A specific hypothesis (ie, laterality of hernias as well as proximity to the xyphoid process and pubic symphysis predisposes to recurrence) was also tested. Methods This was a retrospective study of all laparoscopic incisional hernias undertaken in six centres from 1 January 2004 to 31 December 2010. It comprised a comprehensive review of case notes and a follow-up using a structured telephone questionnaire. Patient demographics, previous medical/surgical history, surgical procedure, postoperative recovery, and perceived effect on quality of life were recorded. Repairs undertaken for primary ventral hernias were excluded. A logistic regression analysis was then fitted with recurrence as the primary outcome. Results A total of 186 cases (91 females) were identified. Median follow-up was 42 months. Telephone interviews were answered by 115/186 (62%) of subjects. Logistic regression analyses suggested that only female sex (odds ratio (OR) 3.53; 95% confidence interval (CI) 1.39–8.97) and diabetes mellitus (3.54; 1–12.56) significantly increased the risk of recurrence. Position of the defect had no statistical effect. Conclusions These data suggest an increased risk of recurrence after laparoscopic incisional hernia repair in females and subjects with diabetes mellitus. These data will help inform surgeons and patients when considering laparoscopic management of incisional hernias. We recommend a centrally hosted, prospectively maintained national/international database to carry out additional research. PMID:25723687

Treatment options for morbidly obese patients with complications from large paraesophageal hernias (PEH) are limited. Simple repair of the PEH has a high recurrence rate and may be associated with poor gastric function. We compared a series of patients who underwent repair of large PEH plus gastrostomy tube gastropexy (PEH-GT) with PEH plus sleeve gastrectomy (PEH-SG). Retrospective review of patients undergoing PEH-SG and patients with PEH-GT was performed. We assessed symptoms of delayed gastric emptying and reflux postoperatively. In selected patients, gastric-emptying studies and upper gastrointestinal contrast studies were also obtained. All patients with large PEH were repaired laparoscopically with sac resection, primary crural closure using pledgeted sutures, and biologic patch onlay. SG for patients undergoing concomitant weight loss surgery (PEH-SG) was performed with linear endoscopic staplers and staple line reinforcement. Patients undergoing PEH repair alone had a gastrostomy tube gastropexy (PEH-GT). Patients had intraoperative endoscopic evaluation and postoperative contrast swallow studies. In a 12-month period, five patients underwent laparoscopic PEH-SG; two of five had previous antireflux surgery and one of five with a previous diagnosis of delayed gastric emptying. Postoperatively, two patients undergoing PEH-SG had readmission for dehydration and odynophagia. Six-month follow-up body mass index was 32 kg/m2 for the PEH-SG group with no hernia recurrence and complete resolution of gastroesophageal reflux disorder symptoms. Six patients underwent PEH-GT, one for acute incarceration and anemia and four with previous antireflux surgery. Follow up at 8 months demonstrated one recurrence, four of six had severe delayed gastric emptying and reflux, three of six had additional hospitalization for poor oral intake, and three of six underwent reoperation for delayed gastric emptying. There were no perforations, leaks, or deaths in either group. Combined

A number of different materials are available for incisional hernia repair. Benefits of the various types are controversial and are partly dependent on the anatomical placement of the mesh. Composite mesh has been introduced to provide tissue ingrowth for strength and a non-adherent side to protect the bowel, these layers being laminated together. This report is on the separation of layers in an infected mesh and adherence of the expanded polytetrafluoroethylene layer to the small bowel.

Major vascular injuries complicating groin hernia repairs are very rare. Five such cases seen at the vascular unit of the Department of Surgery, UNTH, Enugu, Nigeria over a five year period are presented. The patients all of whom were adults (age range 49-65) had initial problems of hypovolaemia due to massive blood loss followed by infection and anaemia. One of the patients died from irreversible shock while still in the Casualty Unit. The vascular injuries were dealt with by either primary repair, vein graft or dacron graft depending on the prevailing conditions e.g. presence or absence of infection. The other 4 patients who had surgery did well postoperatively and on 5 to 58 months follow-up. Emphasis is laid on the underlying causes of these iatrogenic injuries which include inexperience on the part of the operator and inadequate anaesthesia (often wrongly applied local anaesthesia). If this complication however occurs, the wound should be tightly packed and patient sent immediately to a unit with vascular surgical facilities.

Totally extraperitoneal preparation (TEP) of an inguinal hernia is an established method of treating inguinal hernias associated with an acceptable complication rate (2-12%) and low rate of recurrence (0-3%). This is the first reported case of sensorimotor paralysis of the femoral nerve following the complete endoscopic mesh treatment of a primary inguinal hernia to the left side. Following a discussion of the necessary diagnostic and therapeutic steps, traumatic postsurgical paralysis of the nerve as well as spontaneous paralysis of the femoral nerve are discussed. The prognosis is positive given the lack of macroscopic evidence of any direct damage to the nerve.

BACKGROUND: Hernia repair is the second most frequently performed operation in France and in the United States, the prevalence being 36 for every 1000 males. Lowering the recurrence rate by 1% would mean 1000 fewer operations for hernia repair per year in France. METHODS: Between 1983 and 1989, 1578 adult males with a total of 1706 nonrecurrent inguinal hernias were prospectively and randomly allotted to undergo either a Bassini's repair, Cooper's ligament, or Shouldice repair with polypropylene or a Shouldice repair with stainless steel for determination of which technique was associated with the lowest recurrence rate. Fifty-nine hernia repairs were withdrawn after inclusion. Of the 1647 remaining hernias, 52.2% were indirect, 25.6% were direct, and 23.2% were combined. Patients were seen every 6 months for 3 years and then every year. Median follow-up was 5 years 8 months (range, 3 months-8.5 years). RESULTS: At 8.5 years, 5.6% of hernias were lost to follow-up. Ninety-seven hernia repairs failed, 50% during the first 2 years. The actuarial recurrence rate was 7.94% at 8.5 years. The Shouldice repair (stainless steel or polypropylene) was associated with fewer recurrences (6.1%) than either the Bassini's (8.6%) or Cooper's ligament repair (11.2%) technique (p < 0.001). This difference remained significant even when the maximal bias test was used. Fewer recurrences (5.9%) were observed with the stainless steel wire Shouldice repair than with polypropylene version (6.5%), but the difference was not significant. CONCLUSIONS: Shouldice hernia repair provides the patient with the best chances of nonrecurrence regardless of the anatomical type of hernia. The Shouldice hernia repair should be the gold standard for inguinal hernia repair in men and serves as the basis for comparison with all other techniques, be they prosthetic or laparoscopic.

Both Spigelian and Morgagni hernias cause serious morbidity so early diagnosis and timely treatment are necessary. These two types of hernia are more commonly found on the right side of patients. They are rare individually in adults and even rarer in combination. So far, an association between the two hernias has only been reported on the right. We describe the first case of a Spigelian hernia and a Morgagni hernia in a 62-year-old woman, both occurring on the left side. Our accompanying video describes several laparoscopic features that will help lead to early detection and diagnosis.

Introduction. Internal hernias are often misdiagnosed because of their rarity, with subsequent significant morbidity. Case Presentation. A 61-year-old Japanese man with no history of surgery was referred for intermittent abdominal pain. CT suggested the presence of a transmesocolic internal hernia. The patient underwent a surgical procedure and was diagnosed with transmesocolic internal hernia. We found internal herniation of the small intestine loop through a defect in the transverse mesocolon, without any strangulation of the small intestine. We were able to complete the operation laparoscopically. The patient's postoperative course was uneventful and the patient was discharged on postoperative day 6. Discussion. Transmesocolic hernia of the transverse colon is very rare. Transmesocolic hernia of the sigmoid colon accounts for 60% of all other mesocolic hernias. Paraduodenal hernias are difficult to distinguish from internal mesocolic transverse hernias. We can rule out paraduodenal hernias with CT. Conclusion. The patient underwent a surgical procedure and was diagnosed with transmesocolic internal hernia. We report a case of a transmesocolic hernia of the transverse colon with intestinal obstruction that was diagnosed preoperatively and for which laparoscopic surgery was performed. PMID:26246930

Laparoscopic inguinal herniorraphy is a commonly performed procedure given the reported decrease in pain and earlier return to activity when compared with the open approach. Moreover, robotic assistance offers the operating surgeon considerable ergonomic advantages, making it an attractive alternative to conventional laparoscopic herniorraphy. Robotic herniorraphy utilizes the transabdominal preperitoneal approach where following repair peritoneal closure is necessary to avoid mesh exposure to the viscera. Self-anchoring sutures are frequently used to this end given the ease of use and knotless application. We present an unusual case of post-operative small bowel obstruction following robotic inguinal hernia repair caused by the self-anchoring suture used for peritoneal closure. This patient presented 3 days post-procedure with symptoms and cross-sectional imaging indicative of small bowel obstruction with a clear transition point. Underwent laparoscopic lysis of a single adhesive band originating from the loose intraperitoneal end of the suture leading to resolution of symptoms.

A new type of polypropylene (PP) hernia mesh, modified with poly(L-lactic acid) (PLLA), was developed and used to repair rat abdominal wall defect. The PP mesh was first treated with oxygen plasma and then grafted with PLLA in phosphorus pentachloride (PCl5 ) solution in dichloride methane. The water contact angle changed during the procedure, and the coverage percentage of PLLA on the PP was about 80%. ATR-FTIR spectroscopy measurements showed the existence of carbonyl group absorption peak (1756.9 cm(-1) ), and atomic force microscope and scanning electron microscope morphological observation indicated that the surface of the PP mesh was covered with PLLA graft. X-ray photoelectron spectroscopy spectra was used to probe chemical group changes and confirmed that the PLLA was grafted onto the PP. A total of 36 Sprague-Dawley rats were randomly divided into six groups, and they received either modified meshes (experimental groups) or PP meshes (control groups) to repair abdominal wall defects. All animals survived until the end of the experiment. Rats in each group were dissected after the operation (after 1 week, 2 weeks, and 1 month, respectively), and the adhesion effects were evaluated. Sections of the mesh parietal peritoneum overlap were examined histologically and graded for inflammation reaction. Compared with the control groups, the experimental groups showed a better ability to resist peritoneal cavity adhesions (P < 0.05), and there was no increase in inflammation formation (P > 0.05). This new type of PLLA-modified PP mesh displayed an additional property of antiadhesion in animal abdominal wall defect repair.

Laparoscopic ventral hernia repair reportedly yields lower postoperative complications than open repair. We hypothesized that patients undergoing laparoscopic repair would have lower postoperative infectious outcomes. Also, certain preoperative patient characteristics and preoperative hernia characteristics are hypothesized to increase complication risk in both groups. All ventral hernia repairs performed at University of Virginia from January 2004 to January 2006 were reviewed. Primary outcomes included wound healing complications and hernia recurrence. Categorical data were analyzed with χ2 and Fisher’s exact tests. Continuous variables were evaluated with independent t tests and Mann-Whitney U tests. Multivariable logistic regression was performed. A total of 268 repairs (110 open, 158 laparoscopic) were evaluated. Patient and hernia characteristics were similar between groups, though the percents of wound contamination (5.4% vs 0.6%; P = 0.02) and simultaneous surgery (7.2% vs 0%; P = 0.001) were greater in the open procedures. Univariate analysis also revealed that open cases had a greater incidence of postoperative superficial surgical site infection (SSI) (30.0% vs 10.7%; P < 0.0001). Multivariable analysis revealed that both diabetes and open repair were associated with an increased risk of superficial SSI (P = 0.019; odds ratio = 3.512; 95% confidence interval = 1.229–10.037 and P = 0.001; odds ratio = 4.6; 95% confidence interval = 1.9–11.2, respectively). Laparoscopic ventral hernia repair yielded lower rates of postoperative superficial SSI than open surgery. Other pre-operative patient characteristics and preoperative hernia characteristics, with the exception of diabetes, were not found to be associated with an increased risk of postoperative complications.

Ours was a retrospective chart review of all elective open inguinal hernia repairs performed in a single unit at King Edward VIII Hospital, South Africa over an 18-month period. Comparison was made regarding duration of operation, length of hospital stay and complications such as pain, haematoma formation and recurrence between the Lichtenstein and Desarda techniques. The latter was noted to have a shorter operative time and avoided cost and possible complications of mesh usage, which are significant in resource-deprived settings. A larger comparative study with longer follow-up is needed to evaluate the wider suitability of the Desarda repair.

Laparoscopic hernia repair costs more than open repair. This increase in cost largely is because of the use of disposables. Indirect cost benefits of laparoscopic procedure because of a more rapid return to normal activity are different to calculate but may be present for select groups of patients.

Background Cyanoacrylate(CA)-based tissue adhesives, although not widely used, are a feasible option to fix a mesh during abdominal hernia repair, due to its fast action and great bond strength. Their main disadvantage, toxicity, can be mitigated by increasing the length of their alkyl chain. The objective was to assess the in vitro cytotoxicity and in vivo biocompatibility in hernia repair of CAs currently used in clinical practice (Glubran(n-butyl) and Ifabond(n-hexyl)) and a longer-chain CA (OCA(n-octyl)), that has never been used in the medical field. Methods Formaldehyde release and cytotoxicity of unpolymerized(UCAs) and polymerized CAs(PCAs) were evaluated by macroscopic visual assessment, flow cytometry and Alamar Blue assays. In the preclinical evaluation, partial defects were created in the rabbit abdominal wall and repaired by fixing polypropylene prostheses using the CAs. At 14 days post-surgery, animals were euthanized for morphology, macrophage response and cell damage analyses. Results Formaldehyde release was lower as the molecular weight of the monomer increased. The longest side-chain CA(OCA) showed the highest cytotoxicity in the UCA condition. However, after polymerization, was the one that showed better behavior on most occasions. In vivo, all CAs promoted optimal mesh fixation without displacements or detachments. Seroma was evident with the use of Glubran, (four of six animals: 4/6) and Ifabond (2/6), but it was reduced with the use of OCA (1/6). Significantly greater macrophage responses were observed in groups where Glubran and Ifabond were used vs. sutures and OCA. TUNEL-positive cells were significantly higher in the Glubran and OCA groups vs. the suture group. Conclusions Although mild formaldehyde release occurred, OCA was the most cytotoxic during polymerization but the least once cured. The CAs promoted proper mesh fixation and have potential to replace traditional suturing techniques in hernia repair; the CAs exhibited good tissue

Morgagni hernias are uncommon, accounting for only 1-2% of all congenital diaphragmatic hernia. Minimally invasive surgery is today the gold standard treatment. We present a technique using percutaneous suturing and single-site umbilical laparoscopic repair of Morgagni hernia in three children. Recovery was uneventful in all three patients. There was no recurrence and the chest radiograph remained normal during the postoperative follow-up. The percutaneous suturing technique and single-site umbilical laparoscopic repair of a Morgagni hernia is an easy and effective alternative to standard laparoscopic repair.
Almost 20 years after the first laparoscopic inguinal hernia repair was performed, single incision laparoscopic surgery (SILS™) is set to revolutionize minimally invasive surgery. However, the loss of triangulation must be overcome before the technique can be popularized. This study reports the first 100 laparoscopic total extraperitoneal hernia repairs using a single incision. The study cohort comprised 68 patients with a mean age of 44 (range, 18 to 83): 36 unilateral and 32 bilateral hernias. Twelve patients also underwent umbilical hernia repair with the Ventralex patch requiring no additional incisions. A 2.5-cm to 3-cm crescentic incision within the confines of the umbilicus was performed. Standard dissecting instruments and 52-cm/5.5-mm/300 laparoscope were used. Operation times were 50 minutes for unilateral and 80 minutes for bilateral. There was one conversion to conventional 3-port laparoscopic repair and none to open surgery. Outpatient surgery was achieved in all (except one). Analgesic requirements were minimal: 8 Dextropropoxyphene tablets (range, 0 to 20). There were no intraoperative or postoperative complications with a high patient satisfaction score. Single-incision laparoscopic hernia repair is safe and efficient simply by modifying dissection techniques (so-called “inline” and “vertical”). Comparable success can be obtained while negating the risks of bowel and vascular injuries from sharp trocars and achieving improved cosmetic results. PMID:21902942

BACKGROUND: The present clinical trial was designed to compare the results of bilateral inguinal hernia repair between patients who underwent the conventional Stoppa technique and laparoscopic total extraperitoneal repair (LTE) with a single mesh and without staple fixation. PATIENTS AND METHODS: This controlled, randomised clinical trial was conducted at General Surgery and Trauma of the Clinics Hospital, Medical School, the University of São Paulo between September 2010 and February 2011. Totally, 50 male patients, with a bilateral inguinal hernia, older than 25 years were considered eligible for the study. The following parameters were analysed during the early post-operative period: (1) The intensity of surgical trauma, operation time, C-reactive protein (CRP) levels, white blood cell count, bleeding and pain intensity; (2) quality of life assessment; and (3) post-operative complications. RESULTS: LTE procedure was longer than the Stoppa procedure (134.6 min ± 38.3 vs. 90.6 min ± 41.3; P < 0.05). The levels of CRP were higher in the Stoppa group (P < 0.05) but the number of leucocytes, haematocrit, and haemoglobin were similar between the groups (P > 0.05). There was no difference in pain during the 1st and 7th post-operative, physical functioning, physical limitation, the impact of pain on daily activities, and the Carolinas Comfort Scale during the 7th and 15th post-operative (P > 0.05). Complications occurred in 88% of Stoppa group (22 patients) and 64% in LTE group (16 patients) (P < 0.05). CONCLUSION: The comparative study between the Stoppa and LTE approaches for the bilateral inguinal hernia repair demonstrated that: (1) The LTE approach showed less surgical trauma despite the longer operation time; (2) Quality of life during the early post-operative period were similar; and (3) Complication rates were higher in the Stoppa group.

Objective To describe the technique and results of laparoscopic transabdominal preperitoneal (TAPP) hernia repair. Design A case series, with a detailed description of the operative technique. Setting A university affiliated hospital. Patients A consecutive series of 554 patients (494 male, 60 female) who underwent laparoscopic hernia repair in a single institution. The mean follow-up was 14 months. Interventions Laparoscopic TAPP hernia repair was performed in almost all patients. Simple closure was performed in a patient with a strangulated hernia, and a mesh-based repair was used in a patient with bilateral obturator hernias. Main outcome measures Complications and recurrence. Results The laparoscopic TAPP repair was successful in 550 of the 554 patients who underwent 632 hernia repairs. Conversion was necessary in 4 patients. Complications were infrequent and there were no recurrences. Only 3.4% of patients were lost to follow-up. The most frequent complications were urinary retention (27) and hematoma and seroma (38) in the early postoperative period. Neuralgia (11) and hydrocele (10) also occurred. Mesh infection occurred in only 1 patient and port-site hernias in 3 patients. There was 1 death from an acute myocardial infarction. Conclusion Laparoscopic TAPP hernia repair is associated with an exceedingly low recurrence rate and an acceptable complication rate. PMID:9194780

Context: The Darning technique of inguinal hernia repair is a tissue-based technique with documented low recurrence rate in some parts of the world. Though practiced in our setting, little is documented on its outcome. Aims: The aim was to review the outcome of Darning technique of inguinal hernia repair in our setting. Study Design: A descriptive retrospective study. Patients and Methods: Clinical records of all patients who had inguinal hernia repair using the Darning technique between January 2007 and December 2011 in our institution were obtained. Details of sociodemographic data, intraoperative findings and postoperative complications were reviewed. Statistical Analysis Used: simple frequencies, proportions and cross-tabulations. Results: A total of 132 patients whose ages ranged from 15 to 84 years (mean = 49.4 years) with a male: female ratio of 12:1 were studied. Majority of the hernias were right sided (68.9%), mostly indirect (81.8%). The procedures were for emergencies in 17 (12.9%) cases whereas the rest (87.1%) were done electively. Most procedures, 110 (83.3%) were performed under local anesthesia. Surgical site infection was the most common complication occurring in six patients (4.5%), while four patients (3%) had chronic groin pain. At a mean follow-up period of 15 months there were two recurrences (1.5%) both occurring in patients with bilateral hernias (P = 0.001). Conclusions: The Darning technique of inguinal hernia repair is a safe and effective method for inguinal hernia repair in our setting. PMID:25838768

Introduction Lumbar hernia is an uncommon abdominal wall hernia, making its diagnosis and management a challenge to the treating surgeon. Presentation may be misleading and diagnosis often missed. An imaging study forms an indispensable aid in the diagnosis and surgery is the only treatment option. Presentation of case A 42 year old male presented with history of pain in lower back of 4 years duration and was being treated symptomatically over 4 years with analgesics and physiotherapy. He had noticed a swelling over the left side of his mid-back and consequently on examination was found to have a primary acquired lumbar hernia arising from the deep superior lumbar triangle of Grynfelt. Diagnosis was confirmed by Computed Tomographic imaging. Discussion A lumbar hernia may be primary or secondary with only about 300 cases of primary lumbar hernia reported in literature. Lumbar hernias manifest through two possible defects in the posterior abdominal wall, the superior being more common. Management remains surgical with various techniques emerging over the years. The patient at our center underwent an open sublay mesh repair with excellent outcome. Conclusion A surgeon may encounter a primary lumbar hernia perhaps once in his lifetime making it an interesting surgical challenge. Sound anatomical knowledge and adequate imaging are indispensable. Inspite of advances in minimally invasive surgery, it cannot be universally applied to patients with lumbar hernia and management requires a more tailored approach. PMID:26812667

OBJECTIVE: To demonstrate the feasibility of endoscopic extraperitoneal single site (EESS) inguinal hernia repair and compare it outcomes with the conventional totally extraperitoneal (TEP) technique. BACKGROUND: TEP inguinal hernia repair is a widely accepted alternative to conventional open technique with several perioperative advantages. Transumbilical laparoendoscopic singlesite surgery (LESS) is an emerging approach and has been reported for a number of surgical procedures with superior aesthetic results but other advantages need to be proven. PATIENTS AND METHODS: Thirty-eight uncomplicated inguinal hernias were repaired by EESS approach between January 2010 and January 2011. All procedures were performed through a 25 cm infraumbilical incision using the Alexis wound retractor attached to a surgical glove and three trocars. Body mass index, age, operative time, blood loss, complications, conversion rate, analgesia requirement, hospital stay, return to normal activities and patient satisfaction with aesthetic results were analysed and compared with the last 38 matched-pair group of patients who underwent a conventional TEP inguinal hernia repair by the same surgeon. RESULTS: All procedures were performed successfully with no conversion. In both unilateral and bilateral EESS inguinal repairs, the mean operative time was longer than conventional TEP (55± 20 vs. 40± 15 min, P = 0.049 and 70± 15 vs. 55± 10 min, P = 0.014). Aesthetic result was superior in the EESS group (2.88± 0.43 vs. 2.79± 0.51, P = 0.042). There was no difference between the two approaches regarding blood loss, complications, hospital stay, time until returns to normal activities and analgesic requirement. CONCLUSION: EESS inguinal hernia repair is safe and effective, with superior cosmetic results in the treatment of uncomplicated inguinal hernias. Other advantages of this new technique still need to be proven. PMID:25336820

The aim of this study is to determine the effectiveness and biocompatibility of polypropylene mesh for the repair of nasal septal perforations in an animal model on rabbits. A full-thickness nasal septal perforation with a diameter of nearly 10 × 10 mm was created on 12 rabbits, and then the perforation was reconstructed with two different methods. We used mucosal flaps and polypropylene mesh as an interpositional graft in group 1. Only mucosal flaps were used for reconstruction and are identified as group 2. After 4 weeks, we removed the nasal septum of the rabbits and performed histopathological examinations for acute rejection, infection, inflammatory response, fibrosis, and granuloma formation. We found perforation closure rates of 75 and 25 % in groups 1 and 2, respectively. Inflammatory response was seen in all specimens of group 1 (100 %). The inflammatory response was +1 in five of the specimens (62.5 %), +2 in one specimen (12.5 %), and +3 in two specimens (25 %). Mild fibrosis around the mesh was detected in four specimens (50 %), medium-level fibrosis was detected in one (12.5 %), and no fibrosis was detected in three (37.5 %). Severe fibrosis was not seen in any specimens. The foreign-body reaction was limited to a few giant cells, and granuloma formation was seen in two specimens (25 %). The propylene mesh showed excellent biocompatibility with the septal mucosa, and it can, therefore, be used for the repair of septal perforation as an interpositional graft safely.

Pneumomediastinum is an extremely rare complication after laparoscopic inguinal hernia repair. Very few cases have been reported in the surgical literature to date and most reports indicate pneumoperitoneum from the transabdominal preperitoneal approach as a causative factor. This case report describes a patient in whom an elective total extraperitoneal inguinal hernia repair was complicated by a pneumomediastinum without concomitant pneumoperitoneum, and identifies the tracking of air along the anterior extraperitoneal space and endothoracic fascia as a cause. Previous case reports were reviewed and possible etiologies are discussed. PMID:25348336

Therapeutic delays in cases of external incarcerated hernias typically result in increasing morbidity, mortality, and health expenditures. We investigated the diagnostic role of blood fibrinogen level, white blood count (WBC), mean platelet volume (MPV), and platelet distribution width (PDW) in patients with incarcerated hernia. Two groups, each containing 100 patients, were studied. Group A underwent elective, and group B underwent incarcerated and urgent external hernia repair. We observed high fibrinogen and WBC levels but low MPV and PDW values for patients in group B. Contrary to our expectations, we found lower MPV and PDW values in the complicated group than in the elective group. The morbidity rate and cost burden were higher in group B, and the results were statistically significant. Early operation should be recommended for patients with incarcerated external hernias if their fibrinogen and WBC levels are high.

Objective To determine the learning curve (number of operations required) to stabilize operating times and complication rates for a general surgeon doing laparoscopic inguinal hernia repair in a community practice. Design A prospective analysis. Setting A 256-bed secondary-care community hospital. Patients Ninety-eight consecutive patients booked for elective laparoscopic hernia repair on an outpatient basis. Interventions Using the transabdominal preperitoneal approach, 100 operations were carried out to repair 138 groins and a total of 164 separate hernial defects. Outcome measures The number of operations required to decrease operative times and complication rates to a steady level. Results There were no deaths. There were 5 conversions and 10 admissions, all occurring between the 1st and 46th operations. Two reoperations for reasons other than recurrence were required between the 45th and 55th operations. There were 24 other complications. Complications and surgical times began to level off after 50 operations. The 1 readmission was after the 42nd operation. There were 4 recurrences (2.9% recurrence rate), 2 in each group of 50 operations. Both groups of 2 recurrences occurred within the first 10 operations involving the use of a new stapler. Twenty-two other patients had open hernia repairs because laparoscopy was unsuitable for them. Conclusion The learning curve for laparoscopic inguinal hernia repair in the hands of a general surgeon in community practice who is experienced in open herniorraphy and laparoscopic cholecystectomy is at least 50 operations.

The use of mesh has become essential in the repair of abdominal wall incisional hernias. Suture techniques, reapplied after failure of a primary repair, are characterized by recurrence rates of up to 50 percent, whereas the reinforcement of the abdominal wall with surgical mesh has significantly decreased these rates to <10 percent. This article describes the background for the development of mesh with lightweight construction and physiological biomechanical performance.

Summary Between September 2014 and December 2015, 32 patients with inguinal hernia were treated using a new 3D mesh in our department. This mesh is characterized by a multilamellar flower-shaped central core with a flat, large-pore polypropylene ovoid disk that has to be implanted preperitoneally. Compared with the traditional Lichtenstein procedure, we observed a shorter mean duration of surgery and a significantly lower mean visual analogue scale (VAS) postoperative pain score recorded immediately after the procedure in the 3D mesh group. The mean VAS score recoded after 4 and 8 postoperative days showed better results in the 3D mesh group than the control group. Moreover, there was reduced postoperative morbidity in the 3D mesh group than the control group, even if no patients experienced severe complications. PMID:28234593

BACKGROUND: Laparoscopic surgery has been a frequently performed method for inguinal hernia repair. Studies have demonstrated that the laparoscopic transabdominal preperitoneal (TAPP) approach is an appropriate choice for inguinal hernia repair. Single-incision laparoscopic surgery (SILS) was developed to improve the cosmetic effects of conventional laparoscopy. The aim of this study was to evaluate the safety and feasibility of SILS-TAPP compared with TAPP technique. MATERIALS AND METHODS: A total of 148 patients who underwent TAPP or SILS-TAPP in our surgery clinic between December 2012 and January 2015 were enrolled. Data including patient demographics, hernia characteristics, operative time, intraoperative and postoperative complications, length of hospital stay and recurrence rate were retrospectively collected. RESULTS: In total, 60 SILS-TAPP and 88 TAPP procedures were performed in the study period. The two groups were similar in terms of gender, type of hernia, and American Society of Anesthesiologists (ASA) classification score. The patients in the SILS-TAPP group were younger when compared the TAPP group. Port site hernia (PSH) rate was significantly high in the SILS-TAPP group, and all PSHs were recorded in patients with severe comorbidities. The mean operative time has no significant difference in two groups. All SILS procedures were completed successfully without conversion to conventional laparoscopy or open repair. No intraoperative complication was recorded. There was no recurrence during the mean follow-up period of 15.2 ± 3.8 months. CONCLUSION: SILS TAPP for inguinal hernia repair seems to be a feasible, safe method, and is comparable with TAPP technique. However, randomized trials are required to evaluate long-term clinical outcomes. PMID:27251835

Purpose To compare the outcomes between laparoscopic total extraperitoneal (TEP) repair and prolene hernia system (PHS) repair for inguinal hernia. Methods A retrospective analysis of 237 patients scheduled for laparoscopic TEP or PHS repair of groin hernia from 2005 to 2009 was performed. Results The mean age was 52.3 years in TEP group and 55.7 years in PHS group. Of 119 TEP cases, 98 were indirect inguinal hernia, 15 direct type, 5 femoral hernia and 1 complex hernia; Of 118 PHS cases, 100 indirect, 18 direct type. All in TEP group were performed under general anesthesia and 64% of PHS group were performed under spinal or epidural anesthesia. Preoperatively, 10 cases of recurrent inguinal hernia were involved in our study (4 in TEP, 6 in PHS group). The mean operative time was similar in both groups (74.8 in TEP, 71.2 in PHS group), however mean hospital stay (1.6 days in TEP, 3.2 days in PHS group, P = 0.018) and mean usage of analgesics (0.54 times in TEP, 2.03 times in PHS group, P < 0.01), complications (36 cases in TEP, 6 cases in PHS group, P < 0.01) showed statistical differences. There is only 1 case of postoperative recurrence inguinal hernia in PHS group but it has no statistical significance (P = 0.314). Conclusion Compared to PHS repair, laparoscopic TEP repair has some advantages; shorter hospital stay, less frequent need of analgesics; as well as more postoperative complications such as hematoma, seroma, scrotal swelling.

Background Concomitant incisional and parastomal hernias is a challenging condition. We used a hybrid technique of sublay and onlay to treat patients with this condition. Material/Methods The clinical data of 32 consecutive patients treated from February 2008 to April 2014 for concomitant incisional and parastomal hernias were retrospectively reviewed. The mean diameter was 9 (range 4–13) cm of the incisional hernias, and 6 (range 4.5–8) cm of the parastomal hernias. Results The mean operative time was 247 (range 220–290) min. The mean hospital stay was 20 (range 14–27) days. All surgical wounds healed by primary intention. Seven patients had postoperative seroma and were well managed with puncture and compression. All 32 patients were followed up for a mean of 48 (range 5–68) months. Four patients recurred with parastomal hernias and were treated with secondary surgery. No further recurrence occurred until the last follow-up. Conclusions This hybrid technique of sublay and onlay is only suitable for the repair of complex incisional and parastomal hernias.

Informed consent is increasingly being standardized. We sought to evaluate variability in the amount and quality of information desired by patients in choosing whether to undergo elective surgical hernia repair, a prototypical low- to moderate-risk common procedure. Consecutive stable outpatients were asked to assume that they were considering hernia repair and interviewed with a standard questionnaire that asked them to rate their interest in learning about the natural history, pathology, and management of inguinal hernia as well as herniorrhaphy complications and postoperative recovery. Ninety-eight consecutive patients exhibited substantial interpersonal variability in their level of interest in receiving information. Although interest in some types of information tended to correlate with interest in other types of information, patients' degree of interest in receiving information about anesthesia during the procedure was independent of other variables. Education and previous exposure to individuals with hernias also affected interest in receiving potentially important information before deciding whether to consent to hernia surgery. Patients may vary with regard to the information they want to receive when deciding whether to consent to an invasive procedure. It may be preferable to individualize the consent process to patients' preferences rather than adhering to standardized content.

Despite improvements in prosthetics and surgical techniques, the rate of complications following inguinal hernia repair remains high. Among these, discomfort and chronic pain have become a source of increasing concern among surgeons. Poor quality of tissue ingrowth, such as thin scar plates or shrinking scars-typical results with conventional static implants and plugs-may contribute to these adverse events. Recently, a new type of 3D dynamically responsive implant was introduced to the market. This device, designed to be placed fixation-free, seems to induce ingrowth of viable and structured tissue instead of regressive fibrotic scarring. To elucidate the differences in biologic response between the conventional static meshes and this 3D dynamically responsive implant, a histological comparison was planned. The aim of this study was to determine the quality of tissue incorporation in both types of implants excised after short, medium, and long periods post-implantation. The results showed large differences in the biologic responses between the two implant types. Histologically, the 3D dynamic implant showed development of tissue elements more similar to natural abdominal wall structures, such as the ingrowth of loose and well-hydrated connective tissue, well-formed vascular structures, elastic fibers, and mature nerves, with negligible or absent inflammatory response. All these characteristics were completely absent in the conventional static implants, where a persistent inflammatory reaction was associated with thin, hardened, and shrunken fibrotic scar formation. Consequently, as herniation is a degenerative process, the 3D dynamic implants, which induce regeneration of the typical groin components, seem to address its pathogenesis.

Incisional hernia is a frequent complication of abdominal surgery developing in 11-20 % of patients undergoing an abdominal operation. Regarding morbidity and loss of manpower, incisional hernias continue to be a fundamental problem for surgeons. In this experimental study, three commonly used mesh materials (Goretex PTFE; Tutoplast Fascia lata; Tutopatch Pericardium bovine) were compared according to effectiveness, strength, adhesion formation, histological changes, and early complications. Three groups, each consisting of 14 rats, have been formed as group A: polytetrafluoroethylene (PTFE), group B: pericardium bovine and group C: fascia lata. Evaluations were achieved at the end of the first and second postoperative week, respectively. Adhesion formation, wound maturation, bursting pressure, and tensile strength were evaluated. No statistically significant difference regarding adhesion formation was observed between groups although adhesion formation was less significant in PTFE and pericardium bovine groups than in the fascia lata group. Bursting pressure and tensile strength values were significantly higher in PTFE group than in the fascia lata group ( P<0.05). No statistically significant difference was observed between groups regarding wound maturation. In this experimental model, PTFE and pericardium bovine were found to be superior to fascia lata in abdominal wall repair.

The use of advanced imaging technology at international airports is increasing in popularity as a corollary to heightened security concerns across the globe. Operators of airport scanners should be educated about common medical disorders such as inguinal herniae in order to avoid unnecessary harassment of travelers since they will encounter these with increasing frequency.

The authors reviewed the records of 2,468 operations of groin hernia in 2,350 patients, including 277 recurrent hernias updated to January 2005. The data obtained - evaluating technique, results and complications - were used to propose a simple anatomo-clinical classification into three types which could be used to plan the surgical strategy: Type R1: first recurrence ‘high,’ oblique external, reducible hernia with small (<2 cm) defect in non-obese patients, after pure tissue or mesh repairType R2: first recurrence ‘low,’ direct, reducible hernia with small (<2 cm) defect in non-obese patients, after pure tissue or mesh repairType R3: all the other recurrences - including femoral recurrences; recurrent groin hernia with big defect (inguinal eventration); multirecurrent hernias; nonreducible, linked with a controlateral primitive or recurrent hernia; and situations compromised from aggravating factors (for example obesity) or anyway not easily included in R1 or R2, after pure tissue or mesh repair.

Background: Considering that complications and outcome of each method of pediatric inguinal hernia repair are one of the determinants for pediatric surgeons for selection of the appropriate surgical technique, we compared the early and late complications of two inguinal repair techniques, with and without opening the external oblique muscle fascia. Materials and Methods: In this double-blind clinical trial study, boy children aged 1-month to 6 years with diagnosed inguinal hernia were included and randomly allocated into two groups for undergoing two types of hernia repair techniques, with and without opening the external oblique muscle fascia. Surgical complications such as fever, scrotal edema and hematoma, and wound infections classified as early complication and recurrence, testis atrophy and sensory impairment of inguinal area classified as late complications. The rates of mentioned early and late complications were compared in the two interventional groups. Results: In this study, 66 patients were selected and allocated to the two interventional groups. The prevalence of early and late complications in two studied groups were not different significantly in two interventional groups (P > 0.05). Operation time was significantly shorter in inguinal repair techniques without opening the external oblique muscle fascia than the other studied technique (P = 0.001). Conclusion: The findings of our study indicated that though early and late complications of the two repair methods were similar, but the time of procedure was shorter in herniotomy without opening the external oblique muscle, which considered the superiority of this method than inguinal hernia repair with opening the external oblique muscle.

This report describes anesthetic management of a case (a 64-year-old man) who was originally diagnosed as paraesophageal hernia before surgery and later diagnosed as Bochdalek hernia during laparoscopic surgery. Anesthesia was started with oxygen, nitrous oxide, and sevoflurane, and respiration was managed using controlled mechanical ventilation. Although left pneumothorax was noticed during laparoscopic surgery (aeroperitonia pressure: 10 cmH2O), the surgery was performed using the same anesthesia procedure, because hardly any changes were observed on the monitor and vital signs were stable. The surgery was completed without incident. However, postoperative chest X-rays revealed the residual large pneumothorax. A chest drain tube was inserted immediately, after which the pneumothorax was improved. Pneumothorax is considered to be inevitable in cases of laparoscopic repair of Bochdalek hernia. To prevent exacerbation of pneumothorax, anesthetic management should consist of discontinuing the use of nitrous oxide and lowering the aeroperitonia pressure concomitently with the use of positive airway pressure.

Recurrence rate after a congenital diaphragmatic hernia repair is high especially after a patch repair. Recurrence can be asymptomatic, followed by respiratory or gastrointestinal symptoms and the diagnosis is usually confirmed radiologically. We present an unusual case of radiologically diagnosed recurrent left diaphragmatic hernia but at surgery was found to be a gastro-pleural fistula that occurred as a complication following fundoplication surgery.

The case of a 58-year-old male patient who developed a chronic pain syndrome after laparoscopic intraperitoneal onlay mesh for treatment of a large symptomatic umbilical hernia combined with rectus diastasis is reported. Twelve months after an uncomplicated initial surgery, the patient presented with progressive signs of a foreign body sensation and pain in the anterior abdominal wall. Computed tomography examination revealed no pathologic findings but a marked shrinkage of the mesh implant. Because of further progressive symptoms, explorative laparotomy was performed. Mesh shrinkage and adhesions with a surrounding chronic tissue reaction were found as the cause of the pain syndrome. This case demonstrates a case of a chronic pain syndrome due to mesh shrinkage 12 months after initial ventral hernia repair. Mesh shrinkage should therefore be taken into consideration in patients with progressive pain chronic syndromes after laparoscopic ventral hernia repair.

Numerous techniques exist for inguinal hernia treatment. Currently, open mesh tension-free repair is regarded as the repair method of choice. In particular Lichtenstein repair is the most common procedure performed, although several articles have reported long-lasting postoperative pain and a higher recurrence rate than originally reported. This study describes the P.A.D. (Protesi Autoregolantesi Dinamica) prosthesis implantation technique and reports postoperative complications and long-term results. From June 2002 to May 2005 a total of 214 patients underwent P.A.D. prosthesis inguinal repair. All patients were male, with a mean age of 51 years. All hernias were treated via an open inguinal approach using the original technique described by Valenti, with slight modifications. A total of 171'patients (80%) were available to follow-up 3 years after surgery. Early postoperative complications occurred in 14 patients (8.4%). Four patients (12.1%), who had undergone regional anaesthesia, developed urinary retention. Wound infection occurred in 3 patients (1.4%). There were two direct recurrences (0.93%) whereas chronic postoperative inguinal pain was reported in 4.2% of patients. Within the limitations of a short follow-up, our results show that the P.A.D. prosthesis procedure is a reliable technique with a low recurrence rate and low postoperative morbidity.

Background and aims The clinical results of the vertical “vest-over-pants” Mayo repair were evaluated, and the risk factors for incisional hernia recurrence were studied. The purpose of this study is to point out the importance of reducing pre and post operative risk factors in the incisional hernia repair process in order to achieve a physiologically normal abdominal wall. Methods Twenty patients diagnosed with incisional hernia underwent an abdominal reconstruction procedure using the Mayo (Paletot) technique at Bichat Claude Bernard Hospital between 2005 and 2015. All procedures were performed by a single surgeon and all patients were pre-operatively prepared, identifying all coexisting conditions and treating them accordingly before undergoing surgery. Results All patients underwent at least one surgical operation before the hernia repair procedure and a quarter had experienced at least three, prior to this one. Nine patients had a body mass index of >30 kg/m2. Additional risk factors and comorbidities included obesity in 45%, diabetes mellitus in 10%, smoking in 55%, and high blood pressure in 40%. Hernia defect width was from 3 cm (25% F) to 15 cm (5% M) of which nine patients (45%) had a 10 cm defect. Most of the patients had an average hospitalization of 7 days. The patients were carefully monitored and were called on periodic consultations after 3, 6, and 12 months from the moment of the procedure. Patient feedback regarding hernia recurrence and complaints about the scar were noted. Physical examination is essential in determining the hernia recurrence therefore the scar was examined for any abnormalities that may have occurred, which was defined as any palpable or detected fascial defect located within seven centimeters of the hernia repair. Post-operative complications: seroma formation, wound hematoma, superficial and deep wound infection, recurrences and chronic pain were followed and no complications were registered during the follow-up period

Abstract Background: Repair of large ventral hernia defects is associated with high rates of surgical site occurrences (SSO), including surgical site infection (SSI), site dehiscence, seroma, hematoma, and site necrosis. Two common operative strategies exist: Component separation (CS) with primary fascial closure and mesh reinforcement (PFC-CS) and bridged repair (mesh spanning the hernia defect). We hypothesized that: (1) ventral hernia repair (VHR) of large defects with bridged repair is associated with more SSOs than is PFC, and (2) anterior CS is associated with more SSOs than is endoscopic, perforator-sparing, or posterior CS. Methods: Part I of this study was a review of a multi-center database of patients who underwent VHR of a defect ≥8 cm from 2010–2011 with at least one month of follow-up. The primary outcome was SSO. The secondary outcome was recurrence. Part II of this study was a systematic review and meta-analysis of studies comparing bridged repair with PFC and studies comparing different kinds of CS. Results: A total of 108 patients were followed for a median of 16 months (range 1–50 months), of whom 84 underwent PFC-CS and 24 had bridged repairs. Unadjusted results demonstrated no differences between the groups in SSO or recurrence; however, the study was underpowered for this purpose. On meta-analysis, PFC was associated with a lower risk of SSO (odds ratio [OR] = 0.569; 95% confidence interval [CI] = 0.34–0.94) and recurrence (OR = 0.138; 95% CI = 0.08–0.23) compared with bridged repair. On multiple-treatments meta-analysis, both endoscopic and perforator-sparing CS were most likely to be the treatments with the lowest risk of SSO and recurrence. Conclusions: Bridged repair was associated with more SSOs than was PFC, and PFC should be used whenever feasible. Endoscopic and perforator-sparing CS were associated with the fewest complications; however, these conclusions are limited by heterogeneity between studies and

BACKGROUND: Congenital inguinal hernias are a common paediatric surgical problem and herniotomy through a groin incision is the gold standard. Over the last 2 decades minimally invasive surgery (MIS) has challenged this conventional surgery. Over a period, MIS techniques have evolved to making it more minimally invasive – from 3 to 2 and now single port technique. All studies using single port technique are from tertiary care centres. We used a modification of the technique described by Ozgediz et al. and reviewed the clinical outcome of this novel procedure and put forth our experience at a secondary level hospital. MATERIALS AND METHODS: Prospective review of 37 hernias in 31 children (29 male and 2 female) (8 months - 13 years) performed laparoscopically by a single surgeon at a single centre between September 2007 and June 2010. Under laparoscopic guidance, the internal ring was encircled extraperitoneally using a 2-0 non-absorbable suture and knotted extraperitoneally. Data analyzed included operating time, ease of procedure, occult patent processus vaginalis (PPV), complications, and cosmesis. RESULTS: Sixteen right (52%), 14 left (45%) and 1 bilateral hernia (3%) were repaired. Five unilateral hernias (16.66%), all left, had a contralateral PPV that was repaired (P = 0.033). Mean operative time for a unilateral and bilateral repair were 13.20 (8–25) and 20.66 min (17 -27 min) respectively. Only one of the repairs (2.7%) recurred and another had a post operative hydrocoele (2.7%). One case (2.7%) needed an additional port placement due to inability to reduce the contents of hernia completely. There were no stitch abscess/granulomas, obvious spermatic cord injuries, testicular atrophy, or nerve injuries. CONCLUSION: Single port laparoscopic inguinal hernia repair can be safely done in the paediatric population. It permits extension of benefits of minimal access surgery to patients being managed at secondary level hospitals with limited resources. The
Controversy exists on the merits of the various approaches to inguinal repair. Evolution of the classic open repair has culminated in the Shouldice repair. Challenges from newcomers, namely, tension-free repair and laparoscopy, are being examined. These two techniques have a number of disadvantages: the presence of foreign bodies (prostheses) and their implication in cases of infection; the cost of prosthetic material, which is no longer negligible (particularly with expanded polytetrafluoroethylene); and problems of safety in that the laparoscopic approach is no longer a dependable asset except in the hands of a highly specialized and dextrous operator. Still, complications occur with laparoscopic repair that should not be associated with a surgical procedure that is considered benign, safe and cost-effective. Surgeons must recognize the pertinent facts and decide according to their conscience which method of repair to use. PMID:9194781

Laparoscopic transabdominal preperitoneal (TAPP) is gaining popularity as an approach to repairing of inguinal hernia. In many institutions, a disposable ultrasonic energy device is used in the TAPP repair procedure. However, the benefit and necessity of an ultrasonic device are unclear. We have switched to use of a reusable monopolar energy device, and we conducted a retrospective study comparing the surgical results obtained with each of the energy devices. Our study group comprised 241 adults who underwent TAPP repair for inguinal hernia between November 2012 and December 2014. We compared clinical characteristics, and surgical outcomes between patients in whom a disposable ultrasonic energy device was used (n = 116, U group) and those in whom a reusable monopolar energy device (n = 125, M group) was used. There was no statistically significant difference between the 2 groups in age, sex, body mass index, or hernia type. In cases of unilateral hernia, operation time was significantly longer in the U group than in the M group (71.4 vs. 59.4 min, respectively, p < 0.001). No significant difference was found in intraoperative blood loss (2.3 vs 3.9 ml, p = 0.329), postoperative morbidity (5.2 vs 4.0%, p = 0.663), or postoperative hospital stay (2.1 vs 2.2 days, p = 0.336). Our experience and increased competence with the monopolar energy device lead us to conclude that the ultrasonic energy device is unnecessary for simple TAPP repair.

Purpose: We tested the hypothesis that patients treated for localized prostate cancer with radical prostatectomy (RP) have a higher risk of requiring an inguinal hernia (IH) repair than their counterparts treated with external beam radiotherapy (EBRT). Methods and Materials: Within the Quebec Health Plan database, we identified 6,422 men treated with RP and 4,685 men treated with EBRT for localized prostate cancer between 1990 and 2000, in addition to 6,933 control patients who underwent a prostate biopsy. From among that population, we identified patients who underwent a unilateral or bilateral hernia repair after either RP or EBRT. Kaplan-Meier plots showed IH repair-free survival rates. Univariable and multivariable Cox regression models tested the predictors of IH repair after RP or EBRT. Covariates consisted of age, year of surgery, and Charlson Comorbidity Index. Results: IH repair-free survival rates at 1, 2, 5, and 10 years were 96.8, 94.3, 90.5, and 86.2% vs. 98.9, 98.0, 95.4, and 92.2%, respectively, in RP vs. EBRT patients (log-rank test, p < 0.001). IH repair-free survival rates in the biopsy population were 98.3, 97.1, 94.9, and 90.2% at the same four time points. In multivariable Cox regression models, RP predisposed to a 2.3-fold higher risk of IH repair than EBRT (p < 0.001). Besides therapy type, patient age (p < 0.001) represented the only other independent predictor of IH repair. Conclusions: RP predisposes to a higher rate of IH repair relative to EBRT. This observation should be considered at informed consent.

We investigated three sheathing materials (autogenous vein, silastic, and polyglycolic acid fine mesh) using the rat model. Forty rats were divided into five groups of eight animals each. Group A animals underwent transection of the sciatic nerve but had no repair. In Group B, a standard epineural repair was performed. In Groups C, D, and E, the nerve was repaired as in Group B with the addition of autogenous vein, Silastic, and polyglycolic acid fine mesh sheaths, respectively. Nerve regeneration and function were assessed using sciatic functional index, nerve conduction studies, and light microscopy. Sheathing methods showed no statistically significant advantage to standard epineural repair without a sheath.

Introduction Orchialgia following inguinal hernia repair is rare complication and still challenging since there has been no established surgical treatment because of complexity of nerve innervation to the testicular area. Herein we report a case of postoperative orchialgia following Lichtenstein repair, which was successfully treated by mesh removal, orchiectomy and triple neurectomy. Case presentation A 65-year-old man was referred to our department because of chronic right orchialgia following Lichtenstein hernia repair. He walked with a limp and was unable to walk a long distance. Physical examination revealed the presence of meshoma in the groin area and hypoesthesia in the anterior skin of the right scrotum. His right testis was completely atrophic and located not in the scrotum but in the subcutaneous regions of right groin. He was diagnosed as both neuropathic and nociceptive orchialgia and underwent meshoma removal, triple-neurectomy, and orchiectomy to address these issues. Pathological examination revealed that meshoma was integrated with the structures of the spermatic cord, leading to foreign-body reaction and fibrosis around the genital branch of genitofemoral nerve. The resected right testis was completely-scarred without ischemic changes. Orchialgia disappeared immediately after operation and he was able to walk without a limp. Discussions It is important to distinguish between nociceptive and neuropathic orchialgia. Neuroanatomic understanding is essential to guide treatment options. Orchiectomy is an option but should be reserved for refractory cases with evidence of nociceptive pain accompanied by anatomical changes. Conclusions Triple neurectomy should be considered in patients with neuropathic orchialgia. PMID:26476053

Background Parastomal hernia (PH) is the most common complication after ostomy formation. Prophylactic mesh placement may be effective in reducing the rate of PH at the stoma site. The aims of this systematic review were to summarize the evidence with regard to the safety and effectiveness in comparison with the standard procedure without mesh placement and to identify important risk constellations. Method A systematic literature search was performed in PubMed, EMBASE and the Cochrane library with no language or date restrictions. Randomized (RCTs) and non-randomized controlled trials (nRCTs) were included. The main outcomes of interest were PH (primary outcome) rate and stoma-related complications (secondary outcomes) such as stenosis or fistula. Statistical analysis included meta-analyses of pooled data and subgroup analyses. Results Eleven trials (eight RCTs; three nRCTs) with a total of 755 patients were included. PH rate varied from 0% to 59% in the intervention and from 20% to 94% in the control group. RCTs showed a significant reduction of PH rate in the mesh group (OR 0.24; 95% CI 0.10 to 0.58, p = 0.034), whereas included nRCTs did not. No significant differences were observed in postoperative complication rates. Subgroup analyses showed superiority of non-absorbable meshes and sublay mesh positioning in open surgery. Conclusion Prophylactic mesh placement is safe and reduces PH rate. A recommendation for prophylactic non-absorbable meshes in a sublay position can be made for patients undergoing open colorectal operations with end-ostomies. Further research endeavors should focus on patient-oriented outcomes, not only PH rate, with respect to tailored treatment in specific patient populations. PMID:28182642

When no demonstrable cause is uncovered after excluding inflammatory dermatosis, infectious disease or a manifestation of anorectal disease, anogenital pruritus is often described as 'idiopathic'. Lumbosacral radiculopathy was described by Cohen et al. as one of the possible causes of 'idiopathic' anogenital pruritus. We report a case of a patient with chronic pruritus of the right scrotum that was relieved immediately post-ipsilateral inguinal hernia repair. This is, to the best of our knowledge, the first case of neuropathic scrotal pruritus secondary to direct nerve compression by an inguinal hernia. We propose that a proper examination for the presence of inguinal hernia be performed in the work-up for scrotal pruritus.

Duplication of the vas deferens is a rare anomaly, defined as the presence of two distinct vasa deferentia within one spermatic cord, with only 28 cases reported worldwide since 1959. We report the case of a 63-year-old man with a duplicate vas deferens, presenting with abdominal pain from bowel obstruction secondary to incarcerated inguinal hernia. Spermatic cord dissection during hernioplasty revealed duplication of the vas deferens within the right spermatic cord. Doppler ultrasonography confirmed absence of waveforms in both vasa deferentia with arterial signal in the accompanying vessel. The hernia was repaired without complication. This report emphasizes recognition of duplicate vas deferens in avoiding iatrogenic injury and optimizing surgical outcome. PMID:27840763

The formation of an appendico-cutaneous fistula is rare. Few case reports have been published; most describe the formation of a fistula after appendicitis. Here we describe the case of a 79-year-old woman presenting with an appendico-cutaneous fistula after groin hernia repair. She was referred to our outpatient department with a painful mass in the right groin. An ultrasound showed a fluid containing mass. Incision and drainage was performed. After 9 weeks she was referred again with a persisting open wound. Fistulogram and CT scan showed a fistuleous tract involving the appendix. Wound culture showed Escherichia coli. Diagnostic laparoscopy showed an appendix stuck to the ventral wall of the abdomen without any sign of previous infection. After an appendectomy, pathological investigation revealed an appendix sana. After operation, the fistula persisted due to a polypropylene plug from the previous groin hernia correction. The (infected) plug was removed and the fistula healed. PMID:23921697

Hernia repair is one of the most frequently performed surgical interventions that use mesh implants. This article evaluates crucial mesh parameters to facilitate selection of the most appropriate mesh implant, considering raw materials, mesh composition, structure parameters and mechanical parameters. A literature review was performed using the PubMed database. The most important mesh parameters in the selection of a mesh implant are the raw material, structural parameters and mechanical parameters, which should match the physiological conditions. The structural parameters, especially the porosity, are the most important predictors of the biocompatibility performance of synthetic meshes. Meshes with large pores exhibit less inflammatory infiltrate, connective tissue and scar bridging, which allows increased soft tissue ingrowth. The raw material and combination of raw materials of the used mesh, including potential coatings and textile design, strongly impact the inflammatory reaction to the mesh. Synthetic meshes made from innovative polymers combined with surface coating have been demonstrated to exhibit advantageous behavior in specialized fields. Monofilament, large-pore synthetic meshes exhibit advantages. The value of mesh classification based on mesh weight seems to be overestimated. Mechanical properties of meshes, such as anisotropy/isotropy, elasticity and tensile strength, are crucial parameters for predicting mesh performance after implantation. PMID:26523210

Objective To compare vaginal repair augmented by mesh with traditional colporrhaphy for the treatment of pelvic organ prolapse. Design Prospective randomised controlled trial. Setting Tertiary teaching hospital. Population One hundred and thirty-nine women with stage ≥2 prolapse according to the pelvic organ prolapse quantification (POP-Q) system requiring both anterior and posterior compartment repair. Methods Subjects were randomised to anterior and posterior vaginal repair with mesh augmentation (mesh group, n= 69) or traditional anterior and posterior colporrhaphy (no mesh group, n= 70). Main outcome measures The primary outcome was the absence of POP-Q stage ≥2 prolapse at 12 months. Secondary outcomes were symptoms, quality-of-life outcomes and satisfaction with surgery. Complications were also reported. Results For subjects attending the 12-month review, success in the mesh group was 81.0% (51 of 63 subjects) compared with 65.6% (40/61) in the no mesh group and was not significantly different (P-value = 0.07). A high level of satisfaction with surgery and improvements in symptoms and quality-of-life data were observed at 12 months compared to baseline in both groups, but there was no significant difference in these outcomes between the two groups. Vaginal mesh exposure occurred in four women in the mesh group (5.6%). De novo dyspareunia was reported by five of 30 (16.7%) sexually active women in the mesh group and five of 33 (15.2%) in the no mesh group at 12 months. Conclusion In this study, vaginal surgery augmented by mesh did not result in significantly less recurrent prolapse than traditional colporrhaphy 12 months following surgery. PMID:19583714

Introduction Approximately 7% of child patients with inguinal hernias also present with cryptorchidism. On the other hand, combined adult cases are uncommon. Here we report two adult cases of inguinal hernia combined with intra-canalicular cryptorchidism who underwent totally extraperitoneal (TEP) repair with orchiectomy under the same operative view. Presentation of cases We treated two patients (49- and 38-year-old men) with right indirect inguinal hernias and cryptorchidism. Both patients underwent TEP repair with orchiectomy. In operative findings, an atrophic testis was drawn out with a hernia sac from the internal inguinal ring. After the testis was separated from the sac and cord structure was sheared, it was removed. The procedure did not require special techniques and devices. In both patients, the postoperative courses were satisfactory. Discussion To our knowledge, there has been only one such reported case till date which demonstrated the feasibility of TEP repair accompanied by orchiectomy. Conclusions TEP repair with orchiectomy under the same operative view could be safely performed in adults with an inguinal hernia combined with extra-abdominal cryptorchidism. This procedure could be an option for the treatment of such adult patients. PMID:26581081
Context: This study is about documentation of a technique which includes a combination of both hernioplasty and Herniorrhaphy, and its outcome in terms of recurrence rate and postoperative complications. It also compares the outcome of this method with routinely used techniques reported in the literature. Materials and Methods: LR with Herniorrhaphy was performed in the patients admitted with inguinal hernia under concerned surgeon. Their follow-up was assessed after 12 months. Incidences of recurrence rate and other postoperative complications like painful scar, atrophy of testis, urinary retention, hematoma, sinus and infection were noted and compared with other techniques of repair from published data. Statistical Analysis: was carried out by calculating the mean, standard deviation (SD), percentage and incidence rates. Results: LR with Herniorrhaphy performed in 475 patients showed recurrence rate of <<0.01% (n=1) and very low incidences of other postoperative complications like painful scar (0.01%, n=5), sinus (0%, n=0), atrophy of testis (0%, n=0), retention of urine (0.01%, n=6), hematoma (<<0.01%, n=1) and infection (0%, n=0); as compared to published data with different techniques. Conclusion: LR with Herniorrhaphy can be used for open inguinal hernia repair as the gold standard procedure as it has got low recurrence rate and other postoperative complications as compared to other techniques. However, the result of this study is based on the data from a single center, thus we recommend multicentric trials to test the efficacy of this technique. PMID:25478390

Diaphragmatic hernias (DH) occurring after pediatric liver transplantation (LT) are rare. However, such complications have been previously reported in the literature and treatment has always been surgical repair via laparotomy. We report our experience of minimally invasive thoracoscopic approach for repair of DH occurring after LT in pediatric recipients.From April 2010 to December 2014, 7 cases of DH were identified in pediatric LT recipient in Samsung Medical Center. Thoracoscopic repair was attempted in 3 patients. Patients' medical records were retrospectively reviewed.Case 1 was a 12-month-old boy, having received deceased donor LT for biliary atresia (BA) 5 months ago. He presented with dyspnea and left-sided DH was detected. Thoracoscopic repair was successfully done and the boy was discharged at postoperative day 7. Case 2 was a 13-month-old boy, having received deceased donor LT for BA 2 months ago. He presented with vomiting and right-sided DH was detected. Thoracoscopic repair was done along with primary repair of herniated small bowel that was perforated while attempting reduction into the peritoneal cavity. The boy recovered from the surgery without complications and was discharged on the 10th postoperative day. Case 3 was a 43-month-old girl, having received deceased donor LT for Alagille syndrome 28 months ago. She was diagnosed with right-sided DH during steroid pulse therapy for acute rejection. Thoracoscopic repair was attempted but a segment of necrotic bowel was noticed along with bile colored pleural effusion and severe adhesion in the thoracic cavity. She received DH repair with small bowel resection and anastomosis via laparotomy.Thoracoscopic repair was attempted in 3 cases of DH occurring after LT in pediatric recipients. With experience and expertise in pediatric minimally invasive surgery, thoracoscopic approach is feasible in this rare population of patients.

A 60-year-old man with chronic obstructive pulmonary disease and a heavy smoker and drinker presented to the emergency department with left-sided thoracoabdominal pain after falling down the stairs. Initial clinical findings were left-sided chest tenderness with no clinical evidence of subcutaneous emphysema. Twenty-four hours later the patient's respiratory distress increased—repeat chest X-ray showed a left gastrothorax indicative of a ruptured left hemi diaphragm. Diagnostic laparoscopy in the supine position via an umbilical port confirmed the presence of the stomach, spleen and splenic flexure of the colon in the left chest. Laparoscopic reduction of the stomach and colon was performed, but a small upper midline incision was required to reduce the spleen without injury. The diaphragmatic tear was repaired by direct open suture. The patient required a brief period of postoperative ventilation via a tracheostomy. The patient remained well at a 3-month follow-up visit.

Incarcerated diaphragmatic hernia after laparoscopic right hepatectomy is very rare. An 81-year-old man underwent laparoscopic right hepatectomy for giant hepatic hemangioma. Twenty months after the surgery, he began to complain of nausea and abdominal pain and was brought to our hospital. Chest X-ray showed an abdominal gas shadow above the right diaphragm and computed tomography showed herniation of the colon into the right thoracic cavity. We diagnosed ileus due to incarcerated diaphragmatic hernia and performed emergency operation under laparoscopic surgery. After successfully reducing the prolapsed colon back to the abdominal cavity, the diaphragmatic hernia orifice was repaired. Incarcerated diaphragmatic hernia sometimes causes the fatal state. Clinicians must therefore consider such findings a late complication of laparoscopic hepatectomy.

Laparoscopic hernia repairs have been demonstrated to be safe and effective, with less postoperative pain and earlier return to work than with open repairs. Modifications of the laparoscopic technique are evolving that attempt to reduce the overall complication rate while maintaining an effective repair. From January 1994 through July 1995, 67 inguinal hernias on 40 patients were repaired using the total extraperitoneal approach at UCLA Medical Center. Of the 67 hernias, four (6%) were pantaloon, 16 (24%) were indirect, and the remainder (70%) were direct. Three patients of 40 (7.5%) had complications that included seromas (two patients) and urinary retention (one patient). The early recurrence rate is zero, with a mean follow-up period of 6 months. The average time taken off from work was 2 days, with a range of zero to 10 days. Total extraperitoneal laparoscopic hernia repair is a modified technique associated with low early recurrence and few complications. In addition, earlier return to work results in less patient inconvenience, greater productivity, and reduction in medical disability expenses.

BACKGROUND: The aim of this study was to analyse the impact of hiatal hernia repair (HHR) on gastro-oesophageal reflux disease (GERD) in morbidly obese patients with hiatus hernia undergoing laparoscopic sleeve gastrectomy (LSG). MATERIALS AND METHODS: It is a retrospective study involving ten morbidly obese patients with large hiatus hernia diagnosed on pre-operative endoscopy who underwent LSG and simultaneous HHR. The patients were assessed for symptoms of GERD using a Severity symptom score (SS) questionnaire and anti-reflux medications. RESULTS: Of the ten patients, five patients had GERD preoperatively. At the mean follow-up of 11.70 ± 6.07 months after surgery, four patients (80%) showed complete resolution while one patient complained of persistence of symptoms. Endoscopy in this patient revealed resolution of esophagitis indicating that the persistent symptoms were not attributable to reflux. The other five patients without GERD remained free of any symptom attributable to GERD. Thus, in all ten patients, repair of hiatal hernia (HH) during LSG led to either resolution of GERD or prevented any new onset symptom related to GER. CONCLUSION: In morbidly obese patients with HH with or without GERD undergoing LSG, repair of the hiatus hernia helps in amelioration of GERD and prevents any new onset GER. Thus, the presence of HH should not be considered as a contraindication for LSG. PMID:28281472

The risk for developing postoperative complications increases with the degree of surgical trauma, an altered wound healing capability of the patient due to comorbidities and environmental conditions and the selection of an inadequate implant material, the latter offering options for improvement at least in some patients. In general a mesh with large pores made of monofilaments provides a reduced surface area and causes less scarring and inflammation than those with small pores and thereby reduces the rate of scar contraction, pain and the challenge to explant a mesh from a scar bed. When placing the mesh in the abdominal cavity an additional surface coating of polypropylene should prevent the formation of a fistula between mesh and bowel. The risk of recurrence mainly depends on the extent of overlap; however, the flexibility of some meshes may increase the technical difficulties of some implants. In cases of bacterial contamination of the wound there is an increased risk for late onset mesh infection and monofilament meshes offer the best option for complete healing by conservative means. An impaired function of the spermatic cord because of the material, apart from the consequences of the surgical trauma, has not been confirmed in experimental and clinical studies. Revision of mesh sites always is a surgical challenge but could be much easier with implants which are visible in computed tomography (CT) or magnetic resonance imaging (MRI) scans.

Vesicovaginal fistula (VVF) is a devastating social problem. It can either result from obstetric trauma or following gynecological surgeries, malignancy, or radiation. We present a case of a 70-year-old woman who had a VVF following mesh augmentation surgery for anterior compartment prolapse. She required a transvaginal removal of the eroded mesh followed by a transvaginal repair of VVF using a Martius flap, 6 weeks later. Transvaginal removal of mesh is technically feasible and a good approach. Timing and route of surgery should be individualized. PMID:27499600

An otherwise healthy 17-year-old boy presented to the paediatric emergency department with acute severe epigastric pain. An admission abdominal radiograph demonstrated gastric dilation, associated with an elevated left hemidiaphragm. Subsequent barium contrast imaging confirmed the diagnosis of organoaxial acute gastric volvulus (AGV). Emergent exploratory laparoscopy revealed AGV with migration of the stomach, spleen, pancreatic tail, splenic flexure, left kidney and adrenal through a left-sided Bochdalek diaphragmatic hernia. Following careful mobilisation of the displaced structures, a mesh closure of the diaphragmatic defect was performed. The patient's postoperative chest radiograph was unremarkable, and he was discharged on the sixth postoperative day after an uneventful recovery. At 2 months the patient was well and asymptomatic, with normal barium contrast imaging results. PMID:23519514

Introduction Chronic inguinal pain is a frequently occurring problem in athletes. A diagnosis of inguinal disruption is performed by exclusion of other conditions causing groin pain. Up to now, conservative medical management is considered to be the primary treatment for this condition. Relevant large and prospective clinical studies regarding the treatment of inguinal disruption are limited; however, recent studies have shown the benefits of the totally extraperitoneal patch (TEP) technique. This study provides a complete assessment of the inguinal area in athletes with chronic inguinal pain before and after treatment with the TEP hernia repair technique. Methods and analysis We describe the rationale and design of an observational cohort study for surgical treatment with the endoscopic TEP hernia repair technique in athletes with a painful groin (inguinal disruption). The study is being conducted in a high-volume, single centre hospital with specialty in TEP hernia repair. Patients over 18 years, suffering from inguinal pain for at least 3 months during or after playing sports, and whom have not undergone previous inguinal surgery and have received no benefit from physiotherapy are eligible for inclusion. Patients with any another cause of inguinal pain, proven by physical examination, inguinal ultrasound, X-pelvis/hip or MRI are excluded. Primary outcome is reduction in pain after 3 months. Secondary outcomes are pain reduction, physical functioning, and resumption of sport (in frequency and intensity). Ethics and dissemination An unrestricted research grant for general study purposes was assigned to the Hernia Centre. This study itself is not directly subject to the above mentioned research grant or any other financial sponsorship. We intend to publish the outcome of the study, regardless of the findings. All authors will give final approval of the manuscript version to be published. PMID:26739740

BACKGROUND Long-term adhesion-related complications and incisional hernias after abdominal surgery are common and costly. There are few data on the risk of these complications after different abdominal operations. STUDY DESIGN We identified Medicare beneficiaries who underwent endovascular repair of an abdominal aortic aneurysm from 2001–2008 who presumably are not at risk for laparotomy-related complications. We identified all laparoscopic and open operations involving the abdomen, pelvis, or retroperitoneum and categorized them into 5 groups according to invasiveness. We then identified laparotomy-related complications for up to 5 years after the index operation and compared these with the baseline rate of complications in a control group of patients who did not undergo an abdominal operation. RESULTS We studied 85,663 patients, 7,513 (8.8%) of which underwent a laparotomy, including 2,783 major abdominal operations, 709 minor abdominal operations, 963 ventral hernia repairs, 493 retroperitoneal/pelvic operations, and 2,565 laparoscopic operations. Mean age was 76.7 years and 82.0% were male. Major abdominal operations carried the highest risk for adhesion-related complications (14.3% and 25.0% at 2 and 5 years compared with 4.0% and 7.8% for the control group; p < 0.001) and incisional hernias (7.8% and 12.0% compared with 0.6% and 1.2% for the control group; p < 0.001). Laparoscopic operations (4.6% and 10.7% for adhesions, 1.9% and 3.2% for incisional hernias) carried the lowest risk. CONCLUSIONS Late-onset laparotomy-related complications are frequent and their risk extends through 5 years beyond the perioperative period. With the advancement and expansion of laparoscopic techniques and its attendant lower risk for long-term complications, these results can alter the risk-to-benefit profile of various types of abdominal operations and can also strengthen the rationale for additional development of laparoscopic approaches to abdominal operations.

A male patient had a bilateral laparoscopic inguinal hernia repair in 2012. The right-sided hernia was treated with a permanent mesh, and the left-sided hernia received an absorbable mesh. The absorbable TIGR mesh has been proved to be completely absorbed and replaced by new connective tissue after 3 years in sheep. The patient was therefore followed for 3 years by annual magnetic resonance imagings (MRIs) to illustrate the absorption time in humans. During follow-up, the thickness of the absorbable mesh slightly decreased, and at the last clinical examination, the patient was without a recurrence. However, MRI failed to illustrate absorption of the TIGR mesh, perhaps since new connective tissue and the mesh material had the same appearance on the images. In conclusion, MRI was unable to confirm an absorption time of 3 years for the TIGR mesh, and further studies are needed to investigate if the mesh also completely absorbs in humans. PMID:26581219

This retrospective study was to identify perioperative and postoperative complications associated with use of polypropylene mesh for pelvic floor repair in a UK district general hospital in a predominantly obese population. The sample size was 27 women with data retrieved from records. Total mesh was used in 37.1%, isolated anterior mesh in 44.4%, and an isolated posterior mesh in 18.5%. There was a high incidence of obese (BMI kg/m2 > or = 30.0) women (66.67%). The highest recorded thus far. A high proportion of the women (44.4%) were also over the age of 65 years with attendant comorbidities. The age range was 45-77 years. Complications included mesh exposure (7.4%), catheterization at discharge (7.4%), bladder injury during dissection (3.7%) and recurrent prolapse (7.4%). In the carefully selected individuals, polypropylene mesh for prolapse repair appears to be a safe technique to correct pelvic organ prolapse. However, long-term follow-up is needed with further research.

The aim of the study was to assess sexual function in women before and after surgery with transvaginal mesh for pelvic organ prolapse. Women were invited to complete a sexual function questionnaire including the Lemack and the Pelvic Organ Prolapse Urinary Incontinence Sexual Questionnaires (PISQ-12) before undergoing surgery and 1 year after surgery. Eighty-three complete pre and postoperative questionnaires were analyzed. Mean age was 65.1 years. Forty-six were sexually inactive and 37 were sexually active women. Two sexually active women completed the preoperative PISQ-12 questionnaire retrospectively after surgery. There were no significant differences after surgery in the answers to the Lemack questionnaire and PISQ-12 scores. These results suggest that nonabsorbable transvaginal mesh repair of genital prolapse does not impair sexual function 1 year after surgery. Nevertheless, patients should not necessarily expect a significant improvement in sexual function outcome following transvaginal mesh repair for genital prolapse.

Objective The aim of this study was to assess anatomical and functional outcomes 2 years after prolapse repair using vaginal mesh repair system. Methods Women enrolled in a 12-month observational study of outcomes after transvaginal mesh-augmented prolapse repair were invited to participate in an extended follow-up. Subjects completed questionnaires assessing pelvic symptoms, quality of life, global satisfaction, and a pelvic examination for anatomical support and mesh complications. Results Of 118 eligible women, 85 enrolled, 82 provided subjective data at 24 months, and pelvic examination/Pelvic Organ Prolapse Quantification data are available from 79 women. Total, anterior, and posterior Prolift kits were used in 47 (55%), 25 (29%), and 13 (15%), respectively. At baseline, most of the women had stage III prolapse (75%), with the anterior compartment constituting the leading edge in 71% of subjects. At 24 months, Pelvic Organ Prolapse Quantification measures were significantly improved from baseline in all compartments, with 51 (65%) stage 0/I, 25 (31%) stage II, 3 (4%) and stage III (P < 0.001), as were quality of life scores (P < 0.001), with the exception of sexual function. Symptomatic prolapse was reported by 7 (8.5%) women, of which 4 demonstrated prolapse in the nonoperated compartment. Three subjects (4%) reported persistent pelvic pain. The 2-year mesh exposure incidence was at least 13% (11/85). The proportion reporting dyspareunia was 28.9% (13/45) and was unchanged from baseline. The median global satisfaction was 9.3 (range 2.0–10.0). Conclusions Anatomical support, symptom relief, and satisfaction are high 24 months after mesh-augmented vaginal prolapse repair, although mesh exposure and new onset prolapse of the nonoperated compartment are not uncommon.

Introduction Diaphragmatic rupture is an infrequent complication of trauma, occurring in about 5% of those who suffer a severe closed thoracoabdominal injury and about half of the cases are diagnosed early. High morbidity and mortality from bowel strangulation and other sequelae make prompt surgical intervention mandatory. Case presentation Four Brazilian men with a delayed diagnosis of a rare occurrence of traumatic diaphragmatic hernia. Patient one had diaphragmatic rupture on the right side of thorax and the others three patients on the left thoracic side, all they had to approach by a laparotomy and some approach in the chest, either thoracotomy or VATS. This injuries required surgical repositioning of extensively herniated abdominal viscera and intensive postoperative medical management with a careful control of intra-abdominal pressure. Discussion The negative pressure of the thoracic cavity causes a gradually migration of abdominal contents into the chest; this sequestration reduces the abdomen’s ability to maintain the viscera in their normal anatomical position. When the hernia is diagnosed early, the repair is less complicated and requires less invasive surgery. Years after the initial trauma, the diaphragmatic rupture produces dense adhesions between the chest and the abdominal contents. Conclusions All cases demonstrated that surgical difficulty increases when diaphragmatic rupture is not diagnosed early. It should be noted that when trauma to the thoraco-abdominal transition area is blunt or penetrating, a thorough evaluation is required to rule out diaphragmatic rupture and a regular follow-up to monitor late development of this comorbidity.

The aim of this study was to conduct a preclinical evaluation of the behaviour of a new type of abdominal LW prosthesis (Ciberlastic), which was designed with a non-absorbable elastic polyurethane monofilament (Assuplus, Assut Europe, Italy) to allow greater adaptability to mechanical area requirements and higher bio-mimicking with the newly formed surrounding tissues. Our hypothesis was that an increase in the elasticity of the mesh filament could improve the benefits of LW prostheses. To verify our hypothesis, we compared the short- and long-term behaviour of Ciberlastic and Optilene(®) elastic commercial meshes by repairing the partially herniated abdomen in New Zealand White rabbits. The implanted meshes were mechanically and histologically assessed at 14 and 180 days post-implant. We mechanically characterized the partially herniated repaired muscle tissue and also determined mesh shrinkage at different post-implant times. This was followed by a histological study in which the tissue incorporation process was analysed over time. The new prosthesis designed by our group achieved good behaviour that was similar to that of Optilene(®), one of the most popular LW prostheses on the market, with the added advantage of its elastic property. The mechanical properties are significantly lower than those of the polypropylene Optilene(®) mesh, and the new elastic mesh meets the basic mechanical requirements for positioning in the abdominal wall, which was also demonstrated by the absence of recurrences after implantation in the experimental model. We found that the growth of a connective tissue rich in collagen over the hernial defect and the proper deposit of the collagen fibres in the regenerated tissue substantially modified the original properties of the mesh, thereby increasing its biomechanical strength and making the whole tissue/mesh stiffer.

Pseudoaneurysm of the inferior epigastric artery (IEA) is a recognized complication of surgery; however, it is a very rare clinical occurrence. The anatomic position of the IEA subjects patients to possible IEA injury during abdominal wall procedures that are close to the artery, such as insertions of drains, Tenckhoff catheters, laparoscopic trocars, or paracentesis. Treatment options include open surgery, percutaneous coil embolization, embolization with N-butyl cyanoacrylate, sonographic-guided thrombin injection, or sonographic-guided compression. We report the first case of a pseudoaneurysm arising from the IEA after a laparoscopic ventral hernia repair. To our knowledge, 17 IEA pseudoaneurysms have been reported, only 3 of which were spontaneous. The pseudoaneurysm in our patient was successfully treated by percutaneous injection of thrombin by interventional radiology.

The purpose of this study was to evaluate the results of a laparoscopic transabdominal preperitoneal (TAPP) approach to inguinal hernia repair which dissected the entire inguinal floor and repaired the indirect, direct, and femoral areas in all patients without tension. In our series, 183 patients had 205 hernia repairs and were followed for more than 6 months. Of this group, 128 hernias were indirect, 55 direct, 22 pantaloon, 26 recurrent, and 22 bilateral. All 12 females and the first 11 males had a single-buttress repair with polypropylene mesh. The other 160 male patients had a double-buttress repair. With median follow-up of 12 months, ranging from 6 to 21 months, no recurrences were found. Patients returned to normal activity in an average of 1 week. Dissection and buttressing of the entire inguinal floor with mesh appeared to solve the problem of early recurrence first seen in laparoscopic herniorrhaphy.

INTRODUCTION Expenditures on material supplies and medications constitute the greatest per capita costs for surgical missions. We hypothesized that supply acquisition at nonprofit organization (NPO) costs would lead to significant cost-savings compared to supply acquisition at US academic institution costs from the provider perspective for hernia repairs and minor procedures during a surgical mission in the Dominican Republic (DR). METHODS Items acquired for a surgical mission were uniquely QR-coded for accurate consumption accounting. Both NPO and US academic institution unit costs were associated with each item in an electronic inventory system. Medication doses were recorded and QR-codes for consumed items were scanned into a record for each sampled procedure. Mean material costs and cost savings ± SDs were calculated in US dollars for each procedure type. Cost-minimization analyses between the NPO and the US academic institution platforms for each procedure type ensued using a two-tailed Wilcoxon matched-pairs test with α=0.05. Item utilization analyses generated lists of most frequently used materials by procedure type. RESULTS The mean cost savings of supply acquisition at NPO costs for each procedure type were as follows: $482.86 ± $683.79 for unilateral inguinal hernia repair (IHR, n=13); $332.46 ± $184.09 for bilateral inguinal hernia repair (BIHR, n=3); $127.26 ± $13.18 for hydrocelectomy (HC, n=9); $232.92 ± $56.49 for femoral hernia repair (FHR, n=3); $120.90 ± $30.51 for umbilical hernia repair (UHR, n=8); $36.59 ± $17.76 for minor procedures (MP, n=26); and $120.66 ± $14.61 for pediatric inguinal hernia repair (PIHR, n=7). CONCLUSION Supply acquisition at NPO costs leads to significant cost-savings compared to supply acquisition at US academic institution costs from the provider perspective for IHR, HC, UHR, MP, and PIHR during a surgical mission to DR. Item utilization analysis can generate minimum-necessary material lists for each procedure

We describe the case of a patient with a diaphragmatic hernia associated with radiofrequency ablation for hepatocellular carcinoma who was successfully treated by laparoscopic surgery. A 62-year-old man with a long history of hepatitis C-induced liver cirrhosis was admitted to our institution because of recurrent postprandial periumbilical pain. Eight years earlier, he had undergone radiofrequency ablation for hepatocellular carcinoma at hepatic segment VIII. Computed tomography, gastrografin enema examination revealed transverse colon obstruction because of a diaphragmatic hernia. We diagnosed diaphragmatic hernia associated with the prior radiofrequency ablation treatment. The patient underwent laparoscopic repair of the diaphragmatic hernia. Though the patient experienced the recurrence once, relaparoscopic treatment has improved the patient's conditions. Thus, diaphragmatic hernia can develop as a complication of radiofrequency ablation treatment. A laparoscopic approach is safe, feasible, and minimally invasive, even in patients with cirrhosis who develop iatrogenic diaphragmatic hernia as a complication of radiofrequency ablation treatment.

We diagnosed diaphragmatic hernia associated with the prior radiofrequency ablation treatment. The patient underwent laparoscopic repair of the diaphragmatic hernia. Though the patient experienced the recurrence once, relaparoscopic treatment has improved the patient's conditions. Thus, diaphragmatic hernia can develop as a complication of radiofrequency ablation treatment. A laparoscopic approach is safe, feasible, and minimally invasive, even in patients with cirrhosis who develop iatrogenic diaphragmatic hernia as a complication of radiofrequency ablation treatment.

Using the usual diagnostic tools like barium swallow examination, endoscopy, and manometry, we are able to diagnose a hiatal hernia, but it is not possible to predict the size of the hernia opening or, respectively, the size of the hiatal defect. At least a correlation can be expected if the gastroesophageal junction is endoscopically assessed in a retroflexed position, and graded according to Hill. So far, it is not possible to come to a clear conclusion how the hiatal closure during hiatal hernia repair should be performed. There is no consensus on using a mesh, and when using a mesh which type or shape should be used. Further studies including long-term results on this issue are necessary. However, it seems obvious to make the decision depending on certain conditions found during operation, and not on preoperative findings.

Single Incision Endoscopic Surgery (SIES) has emerged as a less invasive surgery among laparoscopic surgeries, and this approach for incisional hernia was reported recently. This is the first report of SIES for an incisional lumbar hernia. A 66-year-old Japanese woman was referred to our institution because of a left flank hernia that developed after left iliac crest bone harvesting. A 20-mm incision was created on the left side of the umbilicus and all three trocars (12, 5, and 5 mm) were inserted into the incision. The hernial defect was 14 × 9 cm and was repaired with intraperitoneal onlay mesh and a prosthetic graft. The postoperative course was uneventful. SIES for lumbar hernia offers a safe and effective outcome equivalent compared to laparoscopic surgery. In addition, SIES is less invasive and has a cosmetic benefit.

Prosthetic meshes used for hernioplasty are usually complicated with chronic pain due to avascular fibrotic scar or mesh shrinkage. In this study, we developed a tissue-engineered mesh (TEM) by seeding autologous bone marrow-derived mesenchymal stem cells onto nanosized fibers decellularized aorta (DA). DA was achieved by decellularizing the aorta sample sequentially with physical, mechanical, biological enzymatic digestion, and chemical detergent processes. The tertiary structure of DA was constituted with micro-, submicro-, and nanosized fibers, and the original strength of fresh aorta was retained. Inguinal hernia rabbit models were treated with TEMs or acellular meshes (AMs). After implantation, TEM-treated rabbit models showed no hernia recurrence, whereas AM-treated animals displayed bulges in inguinal area. At harvest, TEMs were thicker, have less adhesion, and have stronger mechanical strength compared to AMs (P<0.05). Moreover, TEM showed better cell infiltration, tissue regeneration, and neovascularization (P<0.05). Therefore, these cell-seeded DAs with nanosized fibers have potential for use in inguinal hernioplasty. PMID:28260890

Titanium cranioplasty is one of the well-established and widely used techniques for repairing cranial defects. In this paper, we present an improved way to design and create titanium meshes with more evaluation process. Computed tomography scan data of patients were used to create three-dimensional virtual models. Implants were designed with NX ImageWare 13.2 (Siemens PLM Software, Plano, TX). Final titanium meshes were assessed by Geomagic Studio 12 (Geomagic, Inc., Morrisville, NC) and NX ImageWare 13.2.Titanium meshes were designed and applied to cranioplasty surgery on 8 patients. Postoperative results were evaluated by computed tomography scanning and further analyzed with rainbow difference tomography. All patients were satisfied with the outcome. With this method, surgeons, engineers, and patients work together to evaluate and edit implant design. Our method provides better communication and comprehensive evaluation, which result in a satisfying outcome.

We present a rare case of intercostal lung herniation due to blunt trauma. A 40-year-old man was admitted to our hospital with lung herniation due to falling off a donkey. Computed tomography demonstrated a fracture of the 8th left rib, a comminuted fracture of the 9th rib, and lung herniation into the 8th intercostal space. The herniation was repaired using a titanium prosthetic rib, a rib plate, and Prolene mesh via a thoracotomy.

Surgical access to the inguinal region, notably during hernia repairs, exposes the ilioinguinal nerve to the risk of damage at the origin of the neuralgia. The incidence of these post-operative neuropathies and their medicolegal consequences justify this study about the anatomical variations of the ilioinguinal nerve. With the aim of preventing its damage during repairs of groin hernias and identifying the factors of onset of chronic spontaneous neuropathy of the ilioinguinal nerve, we dissected 100 inguinal regions of 51 fresh adult corpses. The nerve was absent in seven cases and double in one case. Out of the 94 ilioinguinal nerves observed, we analyzed the path in relation to the inguinal ligament and the connections with the walls of the inguinal canal and its content. The ilioinguinal nerve travels along the superficial surface of the internal oblique muscle, passing on average 1.015 cm from the inguinal ligament. In one case, the fibers of the internal oblique muscle spanned it in several places. The nerve was antero-funicular in 78.72% of cases and perforated the fascia of the external oblique in 28.72% of cases. The terminal division took place in the inguinal canal in 86% of cases, with terminal branches that sometimes perforated the fascia of the external oblique. These results enabled us to better understand the etiopathogenic aspects of certain neuropathies of the groin and to propose techniques useful for the protection of the nerve during repairs of groin hernias.

Laparoscopic hernia repair is more difficult than open hernia repair. The totally extraperitoneal procedure with 3 trocars on the midline is more comfortable for the surgeon. We studied the impact of the length between the umbilicus and the pubis on the totally extraperitoneal procedure (95 hernias operated on in 70 patients). This length did not influence the totally extraperitoneal procedure in this study. Background: The laparoscopic repair of hernias is considered to be difficult especially for the totally extra-peritoneal technique (TEP) due to a limited working space and different appreciation of the usual anatomical landmarks seen through an anterior approach. The aim of our study has been to answer a question: does the umbilical-pubic distance, which influences the size of the mesh, affect the TEP technique used in the treatment of inguinal hernias? Methods: From January 2001 to May 2011, the umbilical-pubic (UP) distance was measured with a sterile ruler graduated in centimeters in all patients who underwent a symptomatic inguinal hernia by the TEP technique in two hernia surgery centers. The sex, age, BMI, hernia type, UP distance, operation time, hospital stay and complications were prospectively examined based on the medical records. Results: Seventy patients underwent 95 inguinal hernia repairs by the TEP technique. The umbilical-pubic distance average was 14 cm (10 to 22) and a 25 kg/m2 (16–30) average concerning the body mass index (BMI). Seventy percent of patients were treated on an outpatient basis. The postoperative course was very simple. There was no recurrence of hernia within this early postoperative period. Conclusion: The umbilical-pubic distance had no influence on the production of TEP with 3 trocars on the midline in this study. PMID:25392661

INTRODUCTION The prevalence of hiatal hernias and para-oesophageal hernias (PEHs) is lower in Asian populations than in Western populations. Progressive herniation can result in giant PEHs, which are associated with significant morbidity. This article presents the experience of an Asian acute care tertiary hospital in the management of giant PEH and parahiatal hernia. METHODS Surgical records dated between January 2003 and January 2013 from the Department of Surgery, Changi General Hospital, Singapore, were retrospectively reviewed. RESULTS Ten patients underwent surgical repair for giant PEH or parahiatal hernia during the study period. Open surgery was performed for four patients with giant PEH who presented emergently, while elective laparoscopic repair was performed for six patients with either giant PEH or parahiatal hernia (which were preoperatively diagnosed as PEH). Anterior 180° partial fundoplication was performed in eight patients, and mesh reinforcement was used in six patients. The electively repaired patients had minimal or no symptoms during presentation. Gastric volvulus was observed in five patients. There were no cases of mortality. The median follow-up duration was 16.3 months. There were no cases of mesh erosion, complaints of dysphagia or recurrence of PEH in all patients. CONCLUSION Giant PEH and parahiatal hernia are underdiagnosed in Asia. Most patients with giant PEH or parahiatal hernia are asymptomatic; they often present emergently or are incidentally diagnosed. Although surgical outcomes are favourable even with a delayed diagnosis, there should be greater emphasis on early diagnosis and elective repair of these hernias. PMID:26778633

Background Chronic postoperative inguinal pain (CPIP) is the most common long-term complication of inguinal hernia repair. As such procedures are routinely performed, CPIP can be considered a significant burden to global health care. Therefore, adequate preventative measures relevant to surgical practice are investigated. However, as no gold standard research approach is currently available, study and outcome measures differ between studies. The current review aims to provide a qualitative analysis of the literature to seek out if outcomes of CPIP are valid and comparable, facilitating recommendations on the best approach to preventing CPIP. Methods A systematic review of recent studies investigating CPIP was performed, comprising studies published in 2007-2015. Study designs were analyzed regarding the CPIP definitions applied, the use of validated instruments, the availability of a baseline score, and the existence of a minimal follow-up of 12 months. Results Eighty eligible studies were included. In 48 studies, 22 different definitions of CPIP were identified, of which the definition provided by the International Association for the Study of Pain was applied most often. Of the studies included, 53 (66%) used 33 different validated instruments to quantify CPIP. There were 32 studies (40%) that assessed both pain intensity (PI) and quality of life (QOL) with validated tools, 41% and 4% had a validated assessment of only PI or QOL, respectively, and 15% lacked a validated assessment. The visual analog scale and the Short Form 36 (SF36) were most commonly used for measuring PI (73%) and QOL (19%). Assessment of CPIP was unclear in 15% of the studies included. A baseline score was assessed in 45% of the studies, and 75% had a follow-up of at least 12 months. Conclusion The current literature addressing CPIP after inguinal hernia repair has a variable degree of quality and lacks uniformity in outcome measures. Proper comparison of the study results to provide

Modern adjuncts to complex, open ventral hernia repair often include component separation (CS) and/or panniculectomy (PAN). This study examines nationwide data to determine how these techniques impact postoperative complications. The National Surgical Quality Improvement Program database was queried from 2005 to 2013 for inpatient, elective open ventral hernia repairs (OVHR). Cases were grouped by the need for and type of concomitant advancement flaps: OVHR alone (OVHRA), OVHR with CS, OVHR with panniculectomy (PAN), or both CS and PAN (BOTH). Multivariate regression to control for confounding factors was conducted. There were 58,845 OVHR: 51,494 OVHRA, 5,357 CS, 1,617 PAN, and 377 BOTH. Wound complications (OVHRA 8.2%, CS 12.8%, PAN 14.4%, BOTH 17.5%), general complications (15.2%, 24.9%, 25.2%, 31.6%), and major complications (6.9%, 11.4%, 7.2%, 13.5%) were different between groups (P < 0.0001). There was no difference in mortality. Multivariate regression showed CS had higher odds of wound [odds ratio (OR) 1.7, 95% confidence interval (CI) 1.5-2.0], general (OR 1.5, 95% CI: 1.3-1.8), and major complications (OR 2.1, 95%, CI: 1.8-2.4), and longer length of stay by 2.3 days. PAN had higher odds of wound (OR 1.5, 95%, CI: 1.3-1.8) and general complications (OR 1.7, 95%CI: 1.5-2.0). Both CS and PAN had higher odds of wound (OR 2.2, 95%, CI: 1.5-3.2), general (OR 2.5, 95%, CI: 1.8-3.4), and major complications (OR 2.2, 95%CI: 1.4-3.4), and two days longer length of stay. In conclusion, patients undergoing OVHR that require CS or PAN have a higher independent risk of complications, which increases when the procedures are combined.

The implantation of meshes to correct inguinal as well as incisional hernias is widely used in the U.S.A. and Western Europe. The short and long term results of meshes are convincing concerning complications, recurrence rate and patient's comfort. On the other hand side some scientific groups discuss the possibility of malignant tumor development due to implanted meshes. In fact, experimental models exist which demonstrate that soft tissue sarcomas can be induced in mice and rats by implanting artificial materials such as synthetics or metal. Beside millions of hernia repairs using meshes worldwide no patient has been reported with a soft tissue tumor until today. The analyses of molecular markers of proliferation, of apoptosis as well as the modulation of heat shock proteins seem not to prove the carcinogenic potential of meshes. In conclusion, there are no data so far indicating a real risk for humans to develop malignant tumors due to implanted meshes. Therefore we further propagate the implantation of meshes in hernia repair in adult patients.

Bladder hernia is a rare condition, but crural herniation of the bladder into the scrotum is very rare. A case of bladder hernia presenting with urological symptoms is described. A 71-year-old man presented to the urological ward complaining for persistent frequency and nocturia associated with loss offorce and decrease of caliber of the urinary stream and the presence of a large mass of the right scrotum. An IVP (intra venous pyelography) showed a large herniation of the bladder through the right inguinal canal into the scrotum. An inguinal incision was made and a crural hernia was identified. The hernia sac, containing bowel and bladder, was dissectedfreefrom the spermatic cord and the testis and the hernia defect was repaired.
Background Although minimally invasive repair of giant hiatal hernias is a very surgical challenge which requires advanced laparoscopic learning curve, several reports showed that is a safe and effective procedure, with lower morbidity than open approach. In the present study we show the outcomes of 13 patients who underwent a laparoscopic repair of giant hiatal hernia. Methods A total of 13 patients underwent laparoscopic posterior hiatoplasty and Nissen fundoplication. Follow-up evaluation was done clinically at intervals of 3, 6 and 12 months after surgery using the Gastro-oesophageal Reflux Health-Related Quality of Life scale, a barium swallow study, an upper gastrointestinal endoscopy, an oesophageal manometry, a combined ambulatory 24-h multichannel impedance pH and bilirubin monitoring. Anatomic recurrence was defined as any evidence of gastric herniation above the diaphragmatic edge. Results There were no intraoperative complications and no conversions to open technique. Symptomatic GORD-HQL outcomes demonstrated a statistical significant decrease of mean value equal to 3.2 compare to 37.4 of preoperative assessment (p < 0.0001). Combined 24-h multichannel impedance pH and bilirubin monitoring after 12 months did not show any evidence of pathological acid or non acid reflux. Conclusion All patients were satisfied of procedure and no hernia recurrence was recorded in the study group, treated respecting several crucial surgical principles, e.g., complete sac excision, appropriate crural closure, also with direct hiatal defect where possible, and routine use of antireflux procedure.

Sciatic nerve entrapment can occur as post-operative complication of perineal hernia repair when sacrotuberous ligament is incorporated during hernia deficit closure. This results in sciatic sensory loss and paralysis of the hind leg. This study investigated the spatial relationship of sciatic nerve and sacrotuberous ligament and their surface topographic projection of 68 cadavers (29 Beagles and 39 Taiwanese mongrels) with various heights (25–56 cm). By gross dissection, the sacrotuberous ligament and sciatic nerve were exposed and their distance in between was measured along four parts (A, B, C, D) of sacrotuberous ligament. The present study revealed that the C was the section of sacrotuberous ligament where the sciatic nerve and the sacrotuberous ligament are closest to each other. Furthermore, a positive correlation was observed between C and height of the dogs. From the present study, we found that the C in smaller dogs has the shortest distance between the sciatic nerve and the sacrotuberous ligament, and thus the most vulnerable to sciatic nerve entrapment, and needs to be avoided or approached cautiously during perineal hernia repair.

The first description of the transabdominal approach for hernia repair was written by Demetrius Cantemir, Prince of Moldavia and encyclopedic scholar, in his 1716 Latin manuscript "Incrementa et decrementa Aulae Othomaniae" ("The history of the Growth and Decay of the Ottoman Empire"). This manuscript was one of the most important in Eastern Europe at the time. It was first translated in English in 1734 by N. Tyndal, and all subsequent translations into various other languages were based on this english version. The original manuscript now belongs to the Houghton Library of Harvard University, where it was recently discovered in 1984 by V. Candea. Our article presents for the first time the complete account of the surgical procedure performed by Albanian physicians in the prince's palace in Constantinopol. The patient was the Prince's secretary. There is a detailed description of the operation, postoperative therapy and the medical course to recovery. The text presented is translated in English from Annotations of Volume Two, chapter four. We consider it worthwhile to present to the medical community this valuable but less known contribution to the history of medicine.

Intercostal hernias are rare, and usually occur following injuries of the thoracic wall. The scope of this report is to present a case of a 53-year-old obese patient that developed a transdiaphragmatic intercostal hernia. The patient presented with a palpable, sizeable, reducible mass in the right lateral thoracic wall, with evident bowel sounds in the area, 6 months after a motor-vehicle accident. On computed tomography (CT), the hernia sac contained part of the liver and part of the ascending colon. A surgical repair of the defect was performed, using a prosthetic patch. The patient's postoperative course was uneventful and she remains recurrence free at 12 months after surgery. Intercostal hernias should be suspected following high-impact injuries of the thoracic wall, and CT scans will facilitate the diagnosis of intercostal hernia. We consider the surgical repair of the defect, with placement of a prosthetic mesh, as the treatment of choice to ensure a favorable outcome. PMID:25785325
Background The combination of perforated diverticulitis in a lumbar hernia constitutes an extremely rare condition. Case presentation We report a case of a 66 year old Caucasian woman presenting with perforated sigmoid diverticulitis localized in a lumbar hernia following iliac crest bone graft performed 18 years ago. Emergency treatment consisted of laparoscopic peritoneal lavage. Elective sigmoid resection was scheduled four months later. At the same time a laparoscopic hernia repair with a biologic mesh graft was performed. Conclusion This case shows a very seldom clinical presentation of lumbar hernia. Secondary colonic resection and concurrent hernia repair with a biologic implant have proven useful in treating this rare condition. PMID:25051974

ABSTRACT Objective To evaluate inflammatory reaction, fibrosis and neovascularization in dural repairs in Wistar rats using four techniques: simple suture, bovine collagen membrane, silicon mesh and silicon mesh with suture. Methods Thirty Wistar rats were randomized in five groups: the first was the control group, submitted to dural tear only. The others underwent durotomy and simple suture, bovine collagen membrane, silicon mesh and silicon mesh with suture. Animals were euthanized and the spine was submitted to histological evaluation with a score system (ranging from zero to 3) for inflammation, neovascularization and fibrosis. Results Fibrosis was significantly different between simple suture and silicon mesh (p=0.005) and between simple suture and mesh with suture (p=0.015), showing that fibrosis is more intense when a foreign body is used in the repair. Bovine membrane was significantly different from mesh plus suture (p=0.011) regarding vascularization. Inflammation was significantly different between simple suture and bovine collagen membrane. Conclusion Silicon mesh, compared to other commercial products available, is a possible alternative for dural repair. More studies are necessary to confirm these findings. PMID:26761555

We describe a 74-year-old man with repeated aspiration pneumonia who developed gastric obstruction due to giant esophageal hiatal hernia (EHH). We repaired the giant EHH by laparoscopic surgery and subsequently anchored the stomach to the abdominal wall by percutaneous endoscopic gastrostomy (PEG) using gastrofiberscopy. Thereafter, the patient resumed oral intake and was discharged on postoperative day 21. At two years after these procedures, the patient has adequate oral intake and lives at home. Because this condition occurs more frequently in the elderly with comorbidities, laparoscopic surgery contributes to minimally invasive treatment. Furthermore, the procedure combined with concurrent gastropexy via PEG is useful for treating patients who have difficulty swallowing and for preventing recurrent hernia.

Purpose Seroma is among the most common complications of laparoscopic total extraperitoneal (TEP) for especially large indirect inguinal hernia, and may be regarded as a recurrence by some patients. A potential area localized behind the mesh and extending from the inguinal cord into the scrotum may be one of the major etiological factors of this complication. Our aim is to describe a novel technique in preventing pseudorecurrence by using fibrin sealant to close that potential dead space. Methods Forty male patients who underwent laparoscopic TEP for indirect inguinal hernia with at least 100-mL volume were included in this prospective clinical study. While fibrin sealant was used to close the potential dead space in the study group, nothing was used in the control group. The volume of postoperative fluid collection on ultrasound was compared between the groups. Results Patient characteristics and the volumes of hernia sac were similar between the 2 groups. The mean volume of postoperative fluid collection was found as 120.2 mL in the control group and 53.7 mL in the study group, indicating a statistical significance (P < 0.001). Conclusion Minimizing the potential dead space with a fibrin sealant can reduce the amount of postoperative fluid collection, namely the incidence of pseudorecurrence. PMID:27617253

Laparoscopic ventral hernia repair is an operation associated with significant postoperative pain, and regional anaesthetic techniques are of potential benefit. The erector spinae plane (ESP) block performed at the level of the T5 transverse process has recently been described for thoracic surgery, and we hypothesised that performing the ESP block at a lower vertebral level would provide effective abdominal analgesia. We performed pre-operative bilateral ESP blocks with 20-30 ml ropivacaine 0.5% at the level of the T7 transverse process in four patients undergoing laparoscopic ventral hernia repair. Median (range) 24-h opioid consumption was 18.7 mg (0.0-43.0 mg) oral morphine. The highest and lowest median (range) pain scores in the first 24 h were 3.5 (3.0-5.0) and 2.5 (0.0-3.0) on an 11-point numerical rating scale. We also performed the block in a fresh cadaver and assessed the extent of injectate spread using computerised tomography. There was radiographic evidence of spread extending cranially to the upper thoracic levels and caudally as far as the L2-L3 transverse processes. We conclude that the ESP block is a promising regional anaesthetic technique for laparoscopic ventral hernia repair and other abdominal surgery when performed at the level of the T7 transverse process. Its advantages are the ability to block both supra-umbilical and infra-umbilical dermatomes with a single-level injection and its relative simplicity.

Ventral hernia repairs (VHRs) have always been considered standard general surgery cases. Recently, there has been a call for "Centers of Excellence." We sought to investigate outcomes and trends between high- and low-volume centers. The Nationwide Inpatient Sample (NIS) data were analyzed from 1998-1999 (T1) and 2008-2009 (T2) for all VHRs. Hospitals were stratified into high-, medium-, and low-volume centers (HVC/MVC/LVC). Demographics, comorbidities, and outcomes were compared. Surgical cases totaled 22,771 in T1 and 37,044 in T2. In T1, 34.3 per cent were performed in HVC versus 64.2 per cent in T2 (P < 0.0001). LVC cases decreased between eras: 32.6 versus 16.1 per cent (P < 0.0001). Comorbidities and emergent admissions increased with time (P < 0.0001). Mortality was similar in both eras and between volume centers. Length of stay was less in LVC in T2 only (4.2 vs 4.8 days, P < 0.0001). Total charges were higher in HVCs in both eras (P < 0.0001). These remained significant in T2 in multivariate regression (MVR). Hospital volume was not associated with most complications or death in either era with MVR. Charlson comorbidity score, age, and emergent admission were predictors of complications and death. Regionalization has occurred for VHRs. However, most complication and mortality rates are unrelated to volume and are linked to comorbidities, age, and emergencies.

BACKGROUND: The systemic impact of intra-abdominal pressure (IAP) and/or changes in carbon dioxide (CO2) during laparoscopy are not yet well defined. Changes in brain oxygenation have been reported as a possible cause of cerebral hypotension and perfusion. The side effects of anaesthesia could also be involved in these changes, especially in children. To date, no data have been reported on brain oxygenation during routine laparoscopy in paediatric patients. PATIENTS AND METHODS: Brain and peripheral oxygenation were investigated in 10 children (8 male, 2 female) who underwent elective minimally invasive surgery for inguinal hernia repair. Intraoperative transcranial near-infrared spectroscopy to assess regional cerebral oxygen saturation (rScO2), peripheral oxygen saturation using pulse oximetry and heart rate (HR) were monitored at five surgical intervals: Induction of anaesthesia (baseline T1); before CO2 insufflation induced pneumoperitoneum (PP) (T2); CO2 PP insufflation (T3); cessation of CO2 PP (T4); before extubation (T5). RESULTS: rScO2 decreases were recorded immediately after T1 and became significant after insufflation (P = 0.006; rScO2 decreased 3.6 ± 0.38%); restoration of rScO2 was achieved after PP cessation (P = 0.007). The changes in rScO2 were primarily due to IAP increases (P = 0.06). The HR changes were correlated to PP pressure (P < 0.001) and CO2 flow rate (P = 0.001). No significant peripheral effects were noted. CONCLUSIONS: The increase in IAP is a critical determinant in cerebral oxygenation stability during laparoscopic procedures. However, the impact of anaesthesia on adaptive changes should not be underestimated. Close monitoring and close collaboration between the members of the multidisciplinary paediatric team are essential to guarantee the patient's safety during minimally invasive surgical procedures.

Background The transversus abdominis plane (TAP) block is a regional anesthesia technique that effectively reduces the pain intensity and use of analgesia in abdominal surgery. The aim of this study was to determine the utility of the ultrasound-guided TAP block in improving the efficacy of the ultrasound-guided ilioinguinal/iliohypogastric nerve (IIN/IHN) block for intraoperative anesthesia and postoperative pain control in day-case inguinal hernia repair (IHR). Methods We conducted a descriptive study of patients undergoing elective primary unilateral open IHR. Fifty-nine patients were divided into two groups according to the anesthetic technique used: ultrasound-guided TAP block plus ultrasound-guided IIN/IHN block (TAP group) vs. ultrasound-guided IIN/IHN block alone (IIN/IHN group). The outcome measures were the adequacy of anesthesia during surgery and postoperative analgesia. Results Four patients (12.5%) in the TAP group and 10 patients (37.0%) in the IIN/IHN group experienced inadequate anesthesia and needed systemic sedation (P < 0.05). No significant differences in additional local anesthetic volume were found between the two groups. Patients in the TAP group reported lower pain scores at the end of surgery (0.4 ± 0.8 vs. 2.1 ± 2.5, P < 0.01), at 2 hours after surgery (0.8 ± 1.3 vs. 3.0 ± 2.2, P < 0.01), at discharge (1.4 ± 1.2 vs. 4.3 ± 2.2, P < 0.01), and at 24 hours (1.5 ± 1.1 vs. 4.5 ± 2.3, P < 0.01). Conclusions The combination of the TAP and IIN/IHN blocks is associated with better intraoperative anesthesia and lower postoperative pain scores compared with the IIN/IHN block alone. PMID:28184266

Objective To determine age- and sex-specific incidence rates of inguinal hernia repairs (IHR) in a well defined USA population and examine trends over time. Summary Background Data IHR represent a substantial burden to the US healthcare system. An up to date appraisal will identify future healthcare needs. Methods A retrospective review of all IHR performed on adult residents of Olmsted County, MN from 1989 to 2008 was performed. Cases were ascertained through the Rochester Epidemiology Project, a record-linkage system with >97% population coverage. Incidence rates were calculated by using incident cases as the numerator and population counts from the census as the denominator. Trends over time were evaluated using Poisson regression. Results During the study period, a total of 4,026 IHR were performed on 3,599 unique adults. Incidence rates per 100,000 person-years were greater for men: 368 vs 44 for women, and increased with age: from 194 to 648 in men, and from 28 to 108 in women between 30 and 70 years of age. Initial, unilateral IHR comprised 74% of all IHR types. The life-long cumulative incidence of an initial, unilateral or bilateral IHR in adulthood was 42.5% in men and 5.8% in women. Over time (from 1989 to 2008), the incidence of initial, unilateral IHR in men decreased from 474 to 373 (relative reduction, RR=21%). Bilateral IHR increased from 42 to 71 (relative increase=70%), contralateral metachronous IHR decreased from 29 to 11 (RR=62%), and recurrent IHR decreased from 66 to 26 (RR=61%), all changes p<0.001. Conclusions IHR are common, their incidence varies greatly by age and sex, and has decreased substantially over time in Olmsted County, Minnesota. PMID:23388353

Wound complications after large ventral hernia repairs when combined with wide subcutaneous dissection (OVHR/WSD) are common (33 to 66%). We evaluate a novel technique of applying talc to wound subcutaneous tissues to decrease wound complications. We accessed our prospectively collected surgical outcomes database for OVHR/WSD procedures performed. Patients were divided into those that did and did not receive subcutaneous talc (TALC vs NOTALC). Demographics intraoperative and outcomes data were collected and analyzed. The study included 180 patients (n = 74 TALC, n = 106 NOTALC). Demographics were all similar, but hernias were larger in the TALC group. TALC patients had their drains removed earlier (14.6 vs 25.6 days; P < 0.001) with dramatic reduction in postoperative seromas requiring intervention (20.8 to 2.7%; P < 0.001) and cellulitis (39.0 to 20.6%; P = 0.007). Short-term follow-up demonstrates significantly higher recurrence rates in the NOTALC group with each recurrence related to infection. The use of talc in the subcutaneous space of OVHR/WSD results in significantly earlier removal of subcutaneous drains, fewer wound complications, and a decrease in early hernia recurrence. Use of talc in the subcutaneous space at the time of wound closure is an excellent technique to decrease wound complications in large subcutaneous dissections.

Umbilical hernias are a common occurrence in domestic animals and humans but have not been well documented in polar bears. Surgical reduction and herniorrhaphies were performed to correct acquired hernias in the region of the umbilicus in four adult captive polar bears (Ursus maritimus) housed in North American zoos. Two of the four bears were clinically unaffected by their hernias prior to surgery. One bear showed signs of severe discomfort following acute enlargement of the hernia. In another bear, re-herniation led to acute abdominal pain due to gastric entrapment and strangulation. The hernias in three bears were surgically repaired by debridement of the hernia ring and direct apposition of the abdominal wall, while the large defect in the most severely affected bear was closed using polypropylene mesh to prevent excessive tension. The cases in this series demonstrate that while small hernias may remain clinically inconsequential for long periods of time, enlargement or recurrence of the defect can lead to incarceration and acute abdominal crisis. Umbilical herniation has not been reported in free-ranging polar bears, and it is suspected that factors such as body condition, limited exercise, or enclosure design potentially contribute to the development of umbilical hernias in captive polar bears.

Prosthetic mesh can contract by 20-75% of its original size within ten months after implantation. We set out to determine whether this contraction has any effect on testicular or femoral vessel blood flow following open or laparoscopic hernia repair. Twenty patients who underwent mesh repair of a primary unilateral inguinal hernia repair by Open (10) or Laparoscopic (10) methods a median of 3 years previously were investigated by ultrasound to determine the haemodynamic characteristics of the testis and femoral vessels. There was no significant difference in testicular blood flow, volume or echogenicity between the different types of repair or the contralateral side. The vertical and transverse dimensions of the femoral artery and vein were similar in all groups as was blood flow. Mesh contraction following inguinal hernioplasty does not adversely affect the testis or femoral vessels and can be used safely for both anterior and preperitoneal approaches.

Investigations were performed in experiments on 36 dogs. Clinico-morphological results of plasty of artificial defects of the anterior abdominal wall by demineralized matrix of a flat allogeneic bone have shown good taking by tissues. In clinic the demineralized matrix of flat allogeneic bone (scapula, skull fornix) was used in ventral hernias in 36 patients. No recurrent hernias were noted in these patients within 20 months after operation.

Tension-free repairs are performed commonly in inguinal hernia operations. The objective of the present study is to compare the outcomes of three different tension-free repair methods known as Lichtenstein, Rutkow-Robbins, and Gilbert double layer. One-hundred and fifty patients diagnosed with inguinal hernia were randomly split into three groups. The comparisons across groups were carried out in terms of operation length, postoperative pain, femoral vein flow velocity, early and late complications, recurrence rates, length of hospital stay, time required to return to work, and cost analysis. No difference was found between the groups regarding age, gender, type and classification of hernia, postoperative pain, and late complications (p > 0.05). Operation length was 53.70 ± 12.32 min in the Lichtenstein group, 44.29 ± 12.37 min in the Rutkow-Robbins group, and 45.21 ± 14.36 min in the Gilbert group (p < 0.05). Mean preoperative and postoperative femoral vein flow velocity values were 13.88 ± 2.237 and 13.42 ± 2.239 cm/s for Lichtenstein group, 12.64 ± 2.98 and 12.16 ± 2.736 cm/s for Rutkow-Robbins group, and 16.02 ± 3.19 and 15.52 ± 3.358 cm/s for the Gilbert group, respectively. Statistical difference was found between all the groups (p < 0.001). However, no difference was determined between the groups regarding the decrease rates (p = 0.977). Among early complications, hematoma was observed in one (2 %) patient of Lichtenstein group, five (10 %) patients of Rutkow-Robbins group, and three (6 %) patients of Gilbert group (p = 0.033). Cost analysis produced the following results for Lichtenstein, Rutkow-Robbins, and Gilbert groups: US $157.94 ± 50.05, $481.57 ± 11.32, and $501.51 ± 73.59, respectively (p < 0.001). Lichtenstein operation was found to be more advantageous compared with the other techniques in terms of cost analysis as well as having unaffected femoral blood

Introduction Composite biomaterials designed for the repair of abdominal wall defects are composed of a mesh component and a laminar barrier in contact with the visceral peritoneum. This study assesses the behaviour of a new composite mesh by comparing it with two latest-generation composites currently used in clinical practice. Methods Defects (7x5cm) created in the anterior abdominal wall of New Zealand White rabbits were repaired using a polypropylene mesh and the composites: PhysiomeshTM; VentralightTM and a new composite mesh with a three-dimensional macroporous polyester structure and an oxidized collagen/chitosan barrier. Animals were sacrificed on days 14 and 90 postimplant. Specimens were processed to determine host tissue incorporation, gene/protein expression of neo-collagens (RT-PCR/immunofluorescence), macrophage response (RAM-11-immunolabelling) and biomechanical resistance. On postoperative days 7/14, each animal was examined laparoscopically to quantify adhesions between the visceral peritoneum and implant. Results The new composite mesh showed the lowest incidence of seroma in the short term. At each time point, the mesh surface covered with adhesions was greater in controls than composites. By day 14, the implants were fully infiltrated by a loose connective tissue that became denser over time. At 90 days, the peritoneal mesh surface was lined with a stable mesothelium. The new composite mesh induced more rapid tissue maturation than PhysiomeshTM, giving rise to a neoformed tissue containing more type I collagen. In VentralightTM the macrophage reaction was intense and significantly greater than the other composites at both follow-up times. Tensile strengths were similar for each biomaterial. Conclusions All composites showed optimal peritoneal behaviour, inducing good peritoneal regeneration and scarce postoperative adhesion formation. A greater foreign body reaction was observed for VentralightTM. All composites induced good collagen deposition
Background: In abdominal wall reconstruction, the retrorectus plane offers an ideal location for mesh placement. Mesh fixation in this plane is often achieved using transfascial sutures, which risks entrapping intercostal nerves and causing significant pain, and takes time to place. A novel alternative is the use of sutureless self-adhering mesh. Although the use of this mesh in inguinal hernias has been well described, studies on its use in abdominal wall reconstruction are lacking. Methods: Consecutive patients who underwent ventral hernia repair with retrorectus mesh were reviewed. This included patients who received transfascially sutured mesh and those who received sutureless self-adhering mesh. All patients were followed up for at least 12 months. The amount of narcotics required by each patient postoperatively was calculated. Surgical-site occurrences (SSOs) and hernia recurrence and bulge were measured. Results: Twenty-six patients underwent abdominal wall reconstruction with retrorectus mesh. This included 12 patients with transfascially sutured mesh and 14 patients with self-adhering mesh. Mean follow-up was 600 days. Baseline characteristics were similar between the 2 groups. Patients receiving self-adhering mesh required significantly less narcotics than patients with transfascially sutured mesh. There were no significant differences in the rate of SSOs between the 2 groups. No hernia recurrences, bulges, or chronic pain occurred in either group. Conclusions: This is the first study to compare the outcomes of retrorectus self-adhering mesh and transfascially sutured mesh in abdominal wall reconstruction. Our results show low rates of SSO, recurrence, and bulge with both options, with significantly less acute pain with self-adhering mesh. PMID:27975037
Background Inguinal hernia is a common condition and its repair (herniorrhaphy) is one of the most commonly performed procedures in general surgery. The Lichtenstein herniorrhaphy technique is a widely used and effective surgery that uses mesh to reinforce the area of weakness. Although a wide range of mesh sizes are available for use in hernia repair, in low-resource health care settings the provision of multiple products may not be supportable and it may be necessary for the provision and use of a single mesh size. This study aimed to determine whether the recommended 7.0 cm x 15.0 cm size is an appropriate single mesh size. Methods In order to determine the optimal mesh size according to recommended surgical practices, in vivo measurements of key dimensions of the inguinal floor were taken in patients undergoing herniorrhaphy. Results Measurements were taken in 43 patients: 40 men and 3 women, mean age 43 years (SD 13.6); 39 with indirect hernias, 4 with direct. Allowing for recommended mesh overlaps, the optimal mesh size for provision to be appropriate for the majority of patients was determined to be 8.5 cm x 14.0 cm, 21% wider than the mesh size currently recommended for use in Lichtenstein herniorrhaphy. Conclusions An appropriate size for routine provision in low-resource settings, or other settings where the provision of several mesh sizes is not supportable, may be 8.5 cm x 14.0 cm. PMID:23031606

Biological meshes are biomaterials consisting of extracellular matrix that are used in surgery particularly for hernia treatment, thoracic wall reconstruction, or silicone implant-based breast reconstruction. We hypothesized that combination of extracellular matrices with autologous mesenchymal stem cells used for hernia repair would result in increased vascularization and increased strength of incorporation. We cultured autologous adipose-derived stem cells harvested from the inguinal region of Wistar rats on cross-linked and noncross-linked porcine extracellular matrices. In 24 Wistar rats, a standardized 2×4 cm fascial defect was created and repaired with either cross-linked or noncross-linked grafts enriched with stem cells. Non-MSC-enriched grafts were used as controls. The rats were sacrificed at 3 months of age. The specimens were examined for the strength of incorporation, vascularization, cell invasion, foreign body reaction, and capsule formation. Both materials showed cellular ingrowth and neovascularization. Comparison of both tested groups with the controls showed no significant differences in the capsule thickness, foreign body reaction, cellularization, or vascularization. The strength of incorporation of the stem cell-enriched cross-linked extracellular matrix specimens was higher than in acellular specimens, but this result was statistically nonsignificant. In the noncross-linked extracellular matrix, the strength of incorporation was significantly higher in the stem cell group than in the acellular group. Seeding of biological meshes with stem cells does not significantly contribute to their increased vascularization. In cross-linked materials, it does not ensure increased strength of incorporation, in contrast to noncross-linked materials. Owing to the fact that isolation and seeding of stem cells is a very complex procedure, we do not see sufficient benefits for its use in the clinical setting.

Background. When a new surgical technique is brought into a department, it is often experienced surgeons that learn it first and then pass it on to younger surgeons in training. This study seeks to clarify the problems and positive experiences when teaching and training surgeons in the Onstep technique for inguinal hernia repair, seen from the instructor's point of view. Methods. We designed a qualitative study using a focus group to allow participants to elaborate freely and facilitate a discussion. Participants were surgeons with extensive experience in performing the Onstep technique from Germany, UK, France, Belgium, Italy, Greece, and Sweden. Results. Four main themes were found, with one theme covering three subthemes: instruction of others (experience, patient selection, and tailored teaching), comfort, concerns/fear, and anatomy. Conclusion. Surgeons receiving a one-day training course should preferably have experience with other types of hernia repairs. If trainees are inexperienced, the training setup should be a traditional step-by-step programme. A training setup should consist of an explanation of the technique with emphasis on anatomy and difficult parts of the procedure and then a training day should follow. Surgeons teaching surgery can use these findings to improve their everyday practice. PMID:27144225

Parastomal hernia, defined as an "incisional hernia related to an abdominal wall stoma", is a frequent complication after conduit urinary diversion that can negatively impact quality of life and present a clinically significant problem for many patients. Parastomal hernia (PH) rates may be as high as 65% and while many patients are asymptomatic, in some series up to 30% of patients require surgical intervention due to pain, leakage, ostomy appliance problems, urinary obstruction, and rarely bowel obstruction or strangulation. Local tissue repair, stoma relocation, and mesh repairs have been performed to correct PH, however, long-term results have been disappointing with recurrence rates of 30%–76% reported after these techniques. Due to high recurrence rates and the potential morbidity of PH repair, efforts have been made to prevent PH development at the time of the initial surgery. Randomized trials of circumstomal prophylactic mesh placement at the time of colostomy and ileostomy stoma formation have shown significant reductions in PH rates with acceptably low complication profiles. We have placed prophylactic mesh at the time of ileal conduit creation in patients at high risk for PH development and found it to be safe and effective in reducing the PH rates over the short-term. In this review, we describe the clinical and radiographic definitions of PH, the clinical impact and risk factors associated with its development, and the use of prophylactic mesh placement for patients undergoing ileal conduit urinary diversion with the intent of reducing PH rates.

Background and Objective: To determine whether the NiTiNol frame of a novel hernia repair device utilizing polypropylene mesh for inguinal hernioplasty remains stable and intransient without fixation after a minimum of 6 months. Methods: Twenty patients had 27 inguinal hernias repaired using a novel hernia repair device that has a NiTiNol frame without any fixation. Initial single-view, postoperative X-rays were compared with a second X-ray obtained at least 6 months later. The NiTiNol frame, which can be easily visualized on a plain X-ray, was measured in 2 dimensions, as were anatomic landmarks. The measurements obtained and the appearances of the 2 X-rays were compared to determine the percentage of change in device size and device stability with regard to device location and shape. Results: There were minimal changes noted between the 2 sets of measurements obtained with an overall trend towards a slight increase in the size of the hernia repair device. The devices demonstrated intransience of position and stability of shape. Conclusions: The NiTiNol frame of a novel hernia repair device utilizing polypropylene mesh exhibits radiographic evidence of size and shape stability and intransience of position without fixation when used in inguinal hernioplasty after a minimum follow-up of 6 months.

A significant proportion of patients experience chronic post-surgical pain (CPSP) following inguinal hernia surgery. Psychological models are useful in predicting acute pain after surgery, and in predicting the transition from acute to chronic pain in non-surgical contexts. This is a prospective cohort study to investigate psychological (cognitive and emotional) risk factors for CPSP after inguinal hernia surgery. Participants were asked to complete questionnaires before surgery and 1 week and 4 months after surgery. Data collected before surgery and 1 week after surgery were used to predict pain at 4 months. Psychological risk factors assessed included anxiety, depression, fear-avoidance, activity avoidance, catastrophizing, worry about the operation, activity expectations, perceived pain control and optimism. The study included 135 participants; follow-up questionnaires were returned by 119 (88.1%) and 115 (85.2%) participants at 1 week and 4 months after surgery respectively. The incidence of CPSP (pain at 4 months) was 39.5%. After controlling for age, body mass index and surgical variables (e.g. anaesthetic, type of surgery and mesh type used), lower pre-operative optimism was an independent risk factor for CPSP at 4 months; lower pre-operative optimism and lower perceived control over pain at 1 week after surgery predicted higher pain intensity at 4 months. No emotional variables were independently predictive of CPSP. Further research should target these cognitive variables in pre-operative psychological preparation for surgery.

We report a rare case of a 46-year-old woman 2 weeks after a cesarean section with Pfannenstiel incision, who presented at the Emergency Department with a significant abdominal pain accompanied by two episodes of vomiting. After that a clinical examination and an abdominal computed tomography scan were completed, a visceral herniation through Pfannenstiel incision was suspected. The indication of surgical exploration was clear. Finally, the laparotomy revealed a linea arcuata hernia with a hernia of the small intestine. After a reduction of the hernia sac, the defect was repaired and no mesh was placed. An antibiotic treatment with co-amoxicillin for 1 week during the recovery was prescribed. The patient recovered uneventfully and could be discharged by postoperative day 7. PMID:28069882

Background. This study aims to evaluate and compare the results of inguinal herniorrhaphy with mesh in classic and preperitoneal method. Methods. Our study community includes 150 candidate patients for inguinal herniorrhaphy with mesh. Totally, 150 candidate patients for inguinal herniorrhaphy were randomly divided into two groups: (1) classic group in which the floor of the canal was repaired and the mesh was located on the floor of the canal and (2) preperitoneal group in which the mesh was installed under the canal and then the floor was repaired. Results. The frequency of recurrence was 10 (13.3%) and 2 (2.66%) in the classic and preperitoneal group, respectively. The frequency of postsurgical pain was 21 (28%) in the classic group and 9 (12%) in the preperitoneal group. The postsurgical hematoma was observed in 7 (9.3%) and 9 (12%) in the classic and preperitoneal group, respectively. Also, the frequency of postsurgical seroma was 8 (10.7%) and 1 (1.3%) in the patients treated with the classic and preperitoneal method, respectively. Conclusion. The findings of the present study demonstrated that the preperitoneal method is a more suitable method for inguinal herniorrhaphy than the classic one because of fewer complications, according to the findings of this study.

The first description of the transabdominal approach for hernia repair was written by Demetrius Cantemir, Prince of Moldavia and encyclopedic scholar, in his 1716 Latin manuscript "Incrementa et Decrementa Aulae Othmanicae". This manuscript was one of the most important of Eastern Europe at the time. It was first translated in English in 1734, and all subsequent translations into various other languages were based on this English version. The original manuscript now belongs to the Houghton Library of Harvard University, where it was recently rediscovered in 1984 by V. Candea. D. Sluşanschi has made the first Romanian translation of the first two volumes based on the original latin manuscript. This translation is now in press. Our article presents for the first time a fragment of this Romanian translation from the Annotations of Volume two, chapter four. In this fragment, Demetrius Cantemir describes the surgical procedure practiced by Albanian physicians in the prince's palace in Constantinopol. The patient was the secretary of the prince. There is a detailed description of the postsurgical therapy and the medical course to recovery. It was first partially reproduced by Mercy in his book on hernia published in 1892, and more recently by Meade in 1965. We consider useful to present to the medical community this valuable but less known contribution to the history of medicine.

A series of 117 consecutive unselected patients with clinically reducible unilateral inguinal herniae were admitted for short-stay repair. Seven expressed a strong preference for one form of anaesthesia (6 general (GA)) local (LA) and 7 were unfit for GA; these were excluded from the trial. The remaining 103 patients were allocated at random to receive either LA or GA in order to compare the two methods of anaesthesia. The resulting groups (53 LA, 50 GA) were well matched for age and obesity. Perand postoperative symptoms were assessed with linear analogues self-assessment questionnaires. Statistically significant differences were demonstrated between the groups; those patients having LA were able to walk, eat, and pass urine earlier than those having GA, who experienced more nausea, vomiting, sore throat, and headache. The postoperative course and additional symptoms were otherwise similar. Forty-five LA patients experienced mild pain during the operation, but nevertheless 85% of the total group said they would consent to its use again. Ninety-three patients (90%) were discharged at 24 h. LA was applicable to all types of clinically reducible inguinal hernia and was an acceptable, safe, and satisfactory alternative to GA.

Introduction Percutaneous internal ring suturing (PIRS) is a method of laparoscopic herniorrhaphy, i.e. percutaneous closure of the internal inguinal ring under the control of a telescope placed in the umbilicus. Aim To evaluate the usefulness of the PIRS technique. Material and methods Fifty-five children (39 girls and 16 boys) underwent surgery using this method in our institution between 2008 and 2010. Results In 10 cases the presence of an open inguinal canal on the opposite side was also noted during surgery, and umbilical hernia was recognized in 2 patients. In 5 cases it was necessary to convert to the open surgery because of the inability to continue the laparoscopic procedure. In 1 case, male pseudohermaphroditism was diagnosed during surgery. Recurrent inguinal hernia required a conventional method of surgery in 1 child. Other children did not exhibit the characteristics of hernia recurrence. The inguinal canals were followed up with postoperative ultrasound examination in 29 children. In 23 children, the ultrasound examination showed no dilatation of the inguinal canal. In the other 6 children dilatation of the inguinal canal or the presence of fluid within the inguinal canal was observed during ultrasound. In 6 children symptoms such as swelling and soreness around the inguinal canal developed within 3 to 6 months after surgery. Conclusions Inguinal hernia surgery using the PIRS procedure is an alternative, effective, minimally invasive method of surgery. Visualization of the peritoneal cavity allows for detection of other abnormalities, as well as for performing other procedures during the same session (such as closing the contralateral inguinal canal or umbilical hernia surgery).

Background and Aims: Unilateral paravertebral block (PVB) as a sole anaesthetic technique is underutilised even in experienced hands. Hence, this study was undertaken regarding the efficacy and safety of PVB and compared with subarachnoid block (SAB) for inguinal hernia repair procedures. Methods: Sixty-three consenting adult male patients scheduled for unilateral inguinal hernia repair were randomly assigned to receive either PVB or SAB (Group P: PVBs at T10–L2 levels, 5 mL of 0.5% bupivacaine at each segment; Group S: SAB at L3–L4 level with 12.5 mg 0.5% of hyperbaric bupivacaine). Primary objective was to compare duration of post-operative analgesia and time to reach discharge criteria (modified Aldrete scores and modified post-anaesthetic discharge scoring [PADS] scores). Secondary objectives were to compare the block characteristics (time required for performing the block, time to surgical anaesthesia, time to ambulation, time to the first analgesic, total rescue analgesic consumption) and adverse effects. Independent Student's t-test was used for continuous data and Pearson Chi-square test for categorical data. P <0.05 was considered as statistically significant. Results: The duration of post-operative analgesia (min) was 384.57 ± 38.67 in Group P and 194.27 ± 20.30 in Group S (P < 0.05). Modified PADS scores were significantly higher at 4 h and 6 h (P < 0.0001) in Group P. Time to reach the discharge criteria was early in Group P than Group S. Conclusion: PVB provides excellent post-operative analgesic conditions with lesser adverse effects and shorter time to reach the discharge criteria compared to SAB. PMID:27512167

One hundred consecutive recurrences following repair of inguinal hernias have been studied; 62 were direct, 30 indirect, 7 pantaloon and one a femoral hernia. Half the indirect recurrences occurred within a year of repair and probably represented failure to detect a small indirect sac. Later indirect recurrences probably represented failure to repair the internal ring. Nine of the direct hernias were medial funicular recurrences and represented failure to anchor the darn medially. The rest of the direct recurrences were attributable to tissue insufficiency and could probably have been averted by larger tissue bites. Recurrences following inguinal herniorrhaphy remain an all too common problem but can be reduced by meticulous surgical technique. PMID:7339602

The Grynfeltt-Lesshaft hernia is a rare posterior abdominal wall defect that allows for the herniation of retro- and intraperitoneal structures through the upper lumbar triangle. While this hernia may initially present as a small asymptomatic bulge, the defect typically enlarges over time and can become symptomatic with potentially serious complications. In order to avoid that outcome, it is advisable to electively repair Grynfeltt hernias in patients without significant contraindications to surgery. Due to the limited number of lumbar hernioplasties performed, there has not been a large study that definitively identifies the best repair technique. It is generally accepted that abdominal hernias such as these should be repaired by tension-free methods. Both laparoscopic and open techniques are described in modern literature with unique advantages and complications for each. We present the case of an unexpected Grynfeltt hernia diagnosed following an attempted lipoma resection. We chose to perform an open repair involving a combination of fascial approximation and dual-layer polypropylene mesh placement. The patient's recovery was uneventful and there has been no evidence of recurrence at over six months. Our goal herein is to increase awareness of upper lumbar hernias and to discuss approaches to their surgical management. PMID:26697256

Introduction and Hypothesis. We sought to determine the mesh extrusion (vaginal exposure) rates and subject outcomes following IntePro (Type I polypropylene) mesh “kit” repairs for vaginal prolapse. Methods. Data were pooled from two prospective multicenter studies evaluating the safety and efficacy of the Perigee and Apogee (American Medical Systems, Minnetonka, Minn, USA) to treat anterior and posterior/apical prolapses, respectively. Extrusions involving the anterior compartment (AC) or posterior compartment/apex (PC/A) were recorded. Results. Two hundred sixty women underwent mesh placement, with a total of 368 mesh units inserted (173 in the AC and 195 in the PC/A). Extrusions were noted in 13 (7.5%) of AC implants and 27 (13.8%) of PC/A implants through 12 months. No difference was seen between those with and without extrusion in regard to anatomic cure, postoperative painor quality of life at 1 year. Conclusions. Extrusion had no apparent effect on short-term outcomes. Given the unknown long-term sequellae of vaginal mesh exposure, a thorough assessment of risks and benefits of transvaginal mesh placement should be considered at the time of preoperative planning.

Background: Inguinal hernia repair is the most common procedure in general surgery and 80,000 operations are performed annually in Great Britain, 100,000 in France and 700,000 in the US. Given its high frequency has a major impact, both in the medical and economic aspects. Aim: Analyze the immediate postoperative complications comparing mesh versus non mesh hernioplasty. Method: Randomized control trial, with the enrollment of 263 patients underwent surgery for inguinal hernia randomized by randomization table. Treatment (mesh, Lichtenstein or without mesh, Bassini technique) was assigned using sequentially numbered opaque envelopes having fulfilled the inclusion criteria. The variables analyzed were: postoperative pain, seroma, hematoma, infection, return to normal activities and recurrence. Results: The mean age was 55.5 years, 88% patients were male and 12% female. The pain was higher in patients operated with mesh. Conclusions: The inguinal hernia repair mesh group had less immediate postoperative complications and significantly earlier return to work than hernioplasty without mesh, this being one of the most important conclusions.

Background Synthetic meshes are frequently used to reinforce soft tissues. The aim of this translational study is to evaluate tolerance and long-term MRI visibility of two recently developed Gadolinium-modified meshes in a rat animal model. Materials and Methods Gadolinium-poly-ε-caprolactone (Gd-PCL) and Gadolinium-polymethylacrylate (Gd-PMA) modified meshes were implanted in Wistar rats and their tolerance was assessed daily. Inflammation and biocompatibility of the implants were assessed by histology and immunohistochemistry after 30 days post implantation. Implants were visualised by 7T and 3T MRI at day 30 and at day 90. Diffusion of Gadolinium in the tissues of the implanted animals was assessed by Inductively Coupled Plasma Mass Spectrometry. Results Overall Gd-PMA coated implants were better tolerated as compared to those coated with Gd-PCL. In fact, Gd-PMA implants were characterised by a high ratio collagen I/III and good vascularisation of the integration tissues. High resolution images of the coated mesh were obtained in vivo with experimental 7T as well as 3T clinical MRI. Mass spectrometry analyses showed that levels of Gadolinium in animals implanted with coated mesh were similar to those of the control group. Conclusions Meshes coated with Gd-PMA are better tolerated as compared to those coated with Gd-PCL as no signs of erosion or significant inflammation were detected at 30 days post implantation. Also, Gd-PMA coated meshes were clearly visualised with both 7T and 3T MRI devices. This new technique of mesh optimisation may represent a valuable tool in soft tissue repair and management.

PURPOSE: The purpose of this study is to determine whether singleport laparoscopic repair (SLR) for incarcerated inguinal hernia in children is superior toconventional repair (CR) approaches. METHOD: Between March 2013 and September 2013, 126 infants and children treatedwere retrospectively reviewed. All the patients were divided into three groups. Group A (48 patients) underwent trans-umbilical SLR, group B (36 patients) was subjected to trans-umbilical conventional two-port laparoscopic repair (TLR) while the conventional open surgery repair (COR) was performed in group C (42 patients). Data regarding the operating time, bleeding volume, post-operative hydrocele formation, testicular atrophy, cosmetic results, recurrence rate, and duration of hospital stay of the patients were collected. RESULT: All the cases were completed successfully without conversion. The mean operative time for group A was 15 ± 3.9 min and 24 ± 7.2 min for unilateral hernia and bilateral hernia respectively, whereas for group B, it was 13 ± 6.7 min and 23 ± 9.2 min. The mean duration of surgery in group C was 35 ± 5.2 min for unilateral hernia. The recurrence rate was 0% in all the three groups. There were statistically significant differences in theoperating time, bleeding volume, post-operative hydrocele formation, cosmetic results and duration hospital stay between the three groups (P < 0.001). No statistically significant differences between SLR and TLR were observed except the more cosmetic result in SLR. CONCLUSION: SLR is safe and effective, minimally invasive, and is a new technology worth promoting. PMID:27073306

Sciatic hernia is a rare pelvic floor hernia that occurs through the greater or lesser sciatic foramen. Sciatic hernias often present as pelvic pain, particularly in women, and diagnosis can be difficult. Sciatic hernia is one of the rarest forms of internal hernia, which can present as signs and symptoms of small bowel obstruction, swelling in the respective gluteal region or pelvic pain. Transabdominal and transgluteal operative approaches, including laparoscopic repair, have been reported. We present a case of left-sided sciatic hernia with incarcerated small bowel as its contents. The hernia was missed by ultrasonography and plain abdominal radiography, but the clinical features were suggestive of an obturator hernia.

Tension-free vaginal tape (TVT) is commonly considered as the first line of treatment for stress urinary incontinence (SUI) with demonstrated efficacy and limited complications. An 82-year-old woman with complete uterine procidentia and SUI underwent a Le Forte colpocleisis, TVT, posterior repair, and cystoscopy. A 4-cm bulge was noted over the site of the left TVT incision on postoperative day 1. On postoperative day 3, she developed bilious vomiting with slight abdominal distention. Computed tomography scan showed a strangulated left inguinal hernia. An immediate exploratory laparotomy noted an inguinal hernia displaced medially with loops of small bowel in the hernia sac. Although properly positioned, one loop of bowel was perforated by the sling mesh. A small bowel resection was performed and the mesh trimmed below the resection on involved side. At 2 months postoperative visit, the patient was asymptomatic, denied stress or urge incontinence. Vaginal examination noted well-supported vaginal walls.

De Garengeot’s hernia is an eponym for femoral hernia containing vermiform appendix as its content and is named after Rene-Jacques croissant De Garengeot after he first described the condition in 1731. We present a case of a 38-year-old woman who presented with right inguinal swelling for 15 years associated with pain and vomiting for 2 days. Clinical examination revealed an irreducible femoral hernia. Emergency surgery was done and inflamed appendix was found as content of the sac. Appendectomy followed by mesh repair was done. Standard treatment protocol does not exist owing to its rarity and the outcome depends on the time of diagnosis and treatment given. A low inguinal approach is reasonable and use of polypropylene mesh warrants further study. This article is being presented because of its rarity and intends to briefly discuss the surgical pitfalls and considerations through an up-to-date literature review. PMID:28050438

Abstract Background: The purpose of this case presentation is to demonstrate how erosion of mesh into the bladder can initially present with the same symptoms as bladder malignancy. Case Presentation: A 62-year-old Hispanic male presented with 2 years of hematuria along with imaging concerning for a bladder tumor. The patient underwent cystoscopy with biopsy of a lesion at the anterior bladder. It was ultimately determined that a mesh plug from a prior hernia repair had migrated into the bladder. The mesh plug was excised using the Da Vinci Si robot, which allowed for efficient mobilization of the bladder and other anatomic structures, as well as rapid recovery. Conclusion: Our case demonstrates the need to consider mesh erosion as a cause of hematuria and, furthermore, shows how the robotic approach can help facilitate excision of migrated mesh into the bladder.

Although polypropylene has been used as a hernia repair material for nearly 50 years, very little science has been applied to studying the body's effect on this material. It is possible that oxidation of mesh occurs as a result of the chemical structure of polypropylene and the physiological conditions to which it is subjected; this leads to embrittlement of the material, impaired abdominal movement, and chronic pain. It is also possible that lightweight polypropylene meshes undergo less oxidation due to a reduced inflammatory reaction. The objective of this study was to characterize explanted hernia meshes using techniques such as scanning electron microscopy, differential scanning calorimetry, thermogravimetric analysis, and compliance testing to determine whether the mesh density of polypropylene affects the oxidative degradation of the material. The hypothesis was that heavyweight polypropylene would incite a more intense inflammatory response than lightweight polypropylene and thus undergo greater oxidative degradation. Overall, the results support this theory.

Background: The minimal repair technique for sports hernias repairs only the weak area of the posterior abdominal wall along with decompressing the genitofemoral nerve. This technique has been shown to return athletes to competition rapidly. This study compares the clinical outcomes of the minimal repair technique with the traditional modified Bassini repair. Hypothesis: Athletes undergoing the minimal repair technique for a sports hernia would return to play more rapidly compared with athletes undergoing the traditional modified Bassini repair. Methods: A retrospective study of 28 patients who underwent sports hernia repair at the authors’ institution was performed. Fourteen patients underwent the modified Bassini repair, and a second group of 14 patients underwent the minimal repair technique. The 2 groups were compared with respect to time to return to sport, return to original level of competition, and clinical outcomes. Results: Patients in the minimal repair group returned to sports at a median of 5.6 weeks (range, 4-8 weeks), which was significantly faster compared with the modified Bassini repair group, with a median return of 25.8 weeks (range, 4-112 weeks; P = 0.002). Thirteen of 14 patients in the minimal repair group returned to sports at their previous level, while 9 of 14 patients in the Bassini group were able to return to their previous level of sport (P = 0.01). Two patients in each group had recurrent groin pain. One patient in the minimal repair group underwent revision hernia surgery for recurrent pain, while 1 patient in the Bassini group underwent hip arthroscopy for symptomatic hip pain. Conclusion: The minimal repair technique allows athletes with sports hernias to return to play faster than patients treated with the modified Bassini. PMID:24427419

The use of mesh in hernia repair has become common, because of lower recurrence rate and simple application. Data from the meta-analysis and the multi-central studies support the use of meshes in hernia repair. One of the complications due to the hernia repair with mesh is the infection. The incidence range is between 1 and 10%. Triclosan embedded commercial absorbable suture materials are used to reduce surgical site infection rate. This study was planned on mesh infection model, because of the low incidence rate. The agent isolated from mesh infections was mostly Staphylococcus aureus and thus it was used as the infecting agent in this research. To achieve a better therapeutic efficacy, triclosan was formulated in chitosan gels. Chitosan is an attractive biopolymer because of its biocompatible, biodegradable, bioadhesive properties. Gel formulations using chitosans (low, medium and high molecular weight) were prepared in 1% (v/v) acetic acid solution and in vitro release profiles were evaluated. Gel formulations showed release profile extended up to 7 days and high molecular weight chitosan gel formulation was released higher quantity drug than other formulations. Meshes coated with triclosan loaded chitosan gel were used to reduce bacterial count and to prevent mesh infection in the study. 24h and simultaneous bacteria inoculation was used to model mesh infection. The rats were observed for 8 days by means of surgical site infection. On the eighth day, the animals were sacrificed and the grafts were removed. Tissue squeezers were used to liberate bacterias from removed grafts. The isolated suspensions were cultured on blood agar plates and colony-forming units were counted overnight. Grafts coated with triclosan loaded chitosan gel presented satisfactory preventive effect against graft infection.

Purpose: Polypropylene mesh implants are frequently used for pelvic floor reconstruction in women. Yet they vary in size and fixation. The purpose of this study is to compare four mesh products with regard to their anatomical positioning and functionality within the pelvic floor, to determine whether each mesh fits equally well in a female cadaver. Methods: One female pelvis was dissected, opening the retropubic space exposing the endopelvic fascia and demonstrating the arcus tendineus fasciae pelvis (ATFP). Anatomical parameters were measured before and after implanting four meshes via the transobturator approach. Results: The anterior fixation of the ATFP was found to be 5 mm lateral to the symphysis in this cadaver. The endopelvic fascia covered 54.6 cm(2). The obturator nerve was located 35 mm from the white line. The distance of the proximal and lateral points of mesh fixation from the ischial spine or ATFP varied from 0 to 25 mm. The meshes varied in size and anatomical positioning. Conclusion: These observations demonstrate the necessity of developing optimally sized meshes and appropriate introducer techniques that can provide sufficient vaginal support. Surgeons, furthermore, need profound knowledge of anatomy, the patient's pelvic floor defect and the meshes available on the market.

Poor acute pain control and inflammation are important risk factors for Persistent Postsurgical Pain (PPSP). The aim of the study is to investigate, in the context of a prospective cohort of patients undergoing hernia repair, potential risk factors for PPSP. Data about BMI, anxious-depressive disorders, neutrophil-tolymphocyte ratio (NLR), proinflammatory medical comorbidities were collected. An analysis for correlation between comorbidities and PPSP was performed in those patients experiencing chronic pain at 3 months after surgery. Tramadol resulted less effective in pain at movement in patients with a proinflammatory status. Preoperative hypertension and NLR > 4 were correlated with PPSP intensity. Regional anesthesia was significantly protective on PPSP when associated with ketorolac. Patients with pain at 1 month were significantly more prone to develop PPSP at 3 months. NSAIDs or weak opioids are equally effective on acute pain and on PPSP development after IHR, but Ketorolac has better profile in patients with inflammatory background or undergoing regional anesthesia. Drug choice should be based on their potential side effects, patient's profile (comorbidities, preoperative inflammation, and hypertension), and type of anesthesia. Close monitoring is necessary to early detect pain conditions more prone to progress to a chronic syndrome. PMID:27051077

Polypropylene mesh (PPM) is widely used in ventral hernia repair, however is also associated with visceral adhesions when the mesh is exposed to intraabdominal organs. In this study, a composite mesh [ePTFE (expanded polytetrafluoroehylene) + PPM] and sodium hyaluronate/carboxymethyl cellulose (NaHA/CMC) membrane laid under PPM are evaluated in terms of adhesion formation in a rat model of ventral hernia repair. In this experimental study, a 2 x 1 cm of peritoneum and underlying muscle defect was created at the right side of the anterior abdominal wall of 37 male Wistar albino rats. These defects were repaired with 2.5 x 2 cm PPM in group 1 (n = 13), with composite mesh in group 2 (n = 12) and with PPM+NaHA/CMC in group 3 (n = 12). Rats were sacrificed after 14 days and the prosthetic materials were examined for the calculation of surface area percentage covered by adhesions, for organ involvement in the adhesions and for histological evaluation. There was a reduction in the adhesion-covered area in group 2 and group 3. Organ involvement was predominantly seen in group 1. Neoperitoneum was perfect in group 2. Fibrosis and inflammation were higher in group 1. All groups showed adhesiogenic potential to some extent. This potential was maximum with PPM. Both ePTFE and NaHA/CMC displayed similar effects in preventing adhesion formation.

The incarcerated femoral hernia containing the right uterine tube is very rare to see. The case report is important to accumulate knowledge of very rare cases. The diagnosis of the case was established pre-operatively with abdominal computerized tomography (CT) On CT examination, the mass in the hernia sac was not connected with the intestines and a tubal structure on the right side of the uterus was shown to extend out of the abdomen. In the operation, the right uterine tube(RUT) was reduced into the abdomen after its blood supply was shown to be normal. A hernia repair was performed. Sometimes in obese patients, incarcerated femoral or inguinal hernias may not been noted. Ultrasonography, CT and magnetic resonance imaging (MRI) is used frequently to diagnose abdominal wall hernias. The organs in the incarcerated sac must be examined carefully and the viability must be checked. The surgeon must decide whether or not to resect the organs. In our case, strangulation was not found and polypropylene mesh was not used for hernia repair due to a fear of infection of the prosthesis. Incarceration of the uterine tube in the sac is traumatic and this condition may lead to infection. Such conditions may lead to ectopic pregnancy. The patient must be informed about ectopic pregnancy due to a previous incarceration of the tube because ectopic pregnancy may be fatal.

Intraluminal pressure, transmucosal potential difference, and endo-oesophageal pH measurements were studied in patients with hiatal hernia—before and after a hiatal repair. The operation employed is the Collis (1968) repair for uncomplicated hiatal hernia and does not refer to gastroplasty as recommended for peptic stricture (Collis, 1961). Postoperative studies show that the repair approximates the inferior oesophageal sphincter to the hiatus with the production of a single band of raised pressure at the lower end of the oesophagus. This band is similar to that seen in normal subjects and its appearance was associated with cure of the symptoms, abolition of the gastro-oesophageal reflux, and improvement in the function of the inferior oesophageal sphincter and the musculature of the body of the oesophagus. Certain physiological implications of this study are discussed. Images PMID:4724501

Occurrence of deep PETCO(2) drop during surgical lumbar disk repair is rare but dramatic. This case report leads to the diagnosis of retroperitoneal vessels lesions. We review the different diagnosis related to the drop of the PETCO(2) during surgery in the genupectoral position. We recommend that the diagnosis of retroperitoneal vessels lesion have to be suspected early if air embolism occurs during lumbar disk surgery.

A regenerative medicine approach to restore the morphology and function of the diaphragm in congenital diaphragmatic hernia is especially challenging because of the position and flat nature of this organ, allowing cell ingrowth primarily from the perimeter. Use of porous collagen scaffolds for the closure of surgically created diaphragmatic defects in rats has been shown feasible, but better ingrowth of cells, specifically blood vessels and muscle cells, is warranted. To stimulate this process, heparin, a glycosaminoglycan involved in growth factor binding, was covalently bound to porous collagenous scaffolds (14%), with or without vascular endothelial growth factor (VEGF; 0.4 µg/mg scaffold), hepatocyte growth factor (HGF; 0.5 µg/mg scaffold) or a combination of VEGF + HGF (0.2 + 0.5 µg/mg scaffold). All components were located primarily at the outside of scaffolds. Scaffolds were implanted in the diaphragm of rats and evaluated after 2 and 12 weeks. No herniations or eventrations were observed, and in several cases, growth factor-substituted scaffolds showed macroscopically visible blood vessels at the lung site. The addition of heparin led to an accelerated ingrowth of blood vessels at 2 weeks. In all scaffold types, giant cells and immune cells were present primarily at the liver side of the scaffold, and immune cells and individual macrophages at the lung side; these cell types decreased in number from week 2 to week 12. The addition of growth factors did not influence cellular response to the scaffolds, indicating that further optimization with respect to dosage and release profile is needed. PMID:23867845

Textile meshes frequently are implanted in the abdominal wall to reinforce a hernia repair. However, revisions for mesh associated complications confirm that these devices are not completely free of risk. Explanted devices offer an opportunity to define the impact of mesh structure on tissue response. This retrieval study analyses the tissue reaction to 623 polypropylene mesh samples (170 class 1 with large pores, and 453 class 2 with small pores) explanted for pain, infection, or recurrence. Histopathological assessment included morphometry of inflammatory infiltrate (IF) and connective tissue (CT), and of collagen 1/3 ratio. Half of the meshes were removed after more than 23 month. Despite large inter-individual differences removal for infection showed more IF than for pain or recurrence with significant correlation of IF with CT. Class 1 meshes with large pores showed less IF, CT, fistula formation, calcification, and bridging than class 2 meshes with small pores. Meshes removed for recurrence showed a lowered collagen 1/3 ratio in 70%. Large pore class 1 meshes showed an improved tissue response and may be considered as favorable to prevent inflammatory side effects. The presence of lowered collagen 1/3 ratio in most of the samples with recurrences stresses the relevance of an intact healing process. Late manifestation of complications demands long-lasting follow-up.

Wandering spleen and gastric volvulus are two rare entities that have been described in association with congenital diaphragmatic hernia. The diagnosis is difficult and any delay can result in ischemia and necrosis of both organs. We present a case of a 13-year-old girl, previously operated on for anterior diaphragmatic hernia and intrathoracic gastric volvulus, that presented to our service for a subdiaphragmatic gastric volvulus recurrence associated with a wandering spleen. In this report we reviewed the literature, analyzing the clinical presentation, diagnostic assessment, and treatment options of both conditions, in particular in the case associated with diaphragmatic hernia.

Hernia repair evolved from pure tissue repair to mesh repair due to decreased recurrence rates. However, concern exists about mesh-related infections occurring even several years after initial operation. Therefore, a polyvinylidenfluoride (PVDF) mesh material was constructed and surface modified by plasma-induced graft polymerization of acrylic acid (PVDF+PAAc). Antimicrobial treatment was sought by binding of gentamicin (PVDF+PAAc+Gentamicin). In vitro efficacy and cytotoxicity was measured by agar diffusion test, L929 cytotoxicity testing and by analyzing the amount of gentamicin release from the mesh surface. In vivo biocompatibility was evaluated in 45 Sprague-Dawley rats. 7, 21 and 90 days after mesh implantation the amount of inflammatory and connective tissue as well as the percentage of proliferating (Ki67) and apoptotic cells (TUNEL) were analyzed at the perifilamentary region. Agar diffusion tests showed sufficient local antimicrobiotic effects against the bacteria tested after 24h of incubation. No signs of cytotoxicity could be identified by L929 testing. Furthermore, surface modification did not affect the in vivo biocompatibility. At the end of the observation period, no significant differences were found for the perifilamentary amount of inflammatory cells and connective tissue and the percentage of Ki67 and TUNEL positive stained cells. The presented data confirm that an antibiotic surface modification of PVDF mesh samples is feasible. By analyzing cytotoxicity in vitro as well as biocompatibility in vivo no side effects were observed.

Controversy exists as to the best position for insertion of the mesh patch in open inguinal herniorrhaphy. The "inlay" mesh graft, which is laid under the transversalis fascia, has been considered preferable by some authors. But in the Lichtenstein open tension-free inguinal hernia repair, the mesh is preferably placed under the external oblique aponeurosis. It is not an "onlay graft" because it lies under the external oblique and over the internal oblique muscles and transversalis fascia. The possible development of an "interstitial" hernia is without basis and has never been seen. This particular "onlay graft" (more correctly an intermuscular graft) is much simpler to apply and has resulted in almost no recurrences and side effects. Placing the patch between the two oblique muscles is therefore recommended for open tension-free primary inguinal hernioplasties.

Morgagni-Larrey hernia (MH) is an unusual diaphragmatic hernia of the retrosternal region. Few cases of MH, treated laparoscopically, associated with Down's syndrome (DS) have been reported in literature. On October 2004, a DS 40-year-old male was admitted to our Department with mild abdominal pain and nausea. Hematochemical tests were within the normal range. Ultrasonography showed biliary sludge and multiple gallstones. Chest X-ray revealed a right-sided paracardiac mass that appeared as MH after a thoraco-abdominal computed tomography (CT). Four trocars were placed as a routinary cholecystectomy. Abdominal exploration confirmed the presence of a voluminous hernia through a wide diaphragmatic defect (12 cm) on the left side of the falciform ligament, containing the last 20 cm ileal loops and right colon with the third lateral of transverse. After retrograde cholecystectomy and reduction of the herniated ileo-colonic tract from multiple adherences, the defect was repaired with an interrupted 2/0 silk suture and then a running 2/0 polypropylene suture. Postoperative course was complicated by pulmonary edema but subsequently the patient was discharged without further complications and has no recurrence after 2 years. In conclusion, surgery is necessary for symptomatic MH and to prevent possible severe complications. We preferred laparoscopy for the reduced morbidity compared to laparotomy, even if in our case the postoperative course was not uneventful. There are still few comparative data about the modality of closure of the defect between primary repair with nonabsorbable suture material, in case of small defects, or continuous monofilament suture or prosthesis in case of large defects.

Abstract Background Provision of information and behavioural instruction has been demonstrated to improve recovery after surgery. However, patients draw on a range of information sources and it is important to establish which sources patients use and how this influences perceptions and behaviour as they progress along the surgical pathway. In this qualitative, exploratory and longitudinal study, the use of information and instruction were explored from the perspective of people undergoing inguinal hernia repair surgery. Methods Seven participants undergoing inguinal hernia repair surgery were interviewed using semi‐structured interviews 2 weeks before surgery and 2 weeks and 4 months post‐surgery. Nineteen interviews were conducted in total. Topic guides included sources of knowledge, reasons for help‐seeking and opting for surgery and factors influencing return to activity. Data were analysed thematically according to Interpretative Phenomenological Analysis. Findings and conclusions Participants sought information from a range of sources, focusing on informal information sources before surgery and using information and instruction from health‐care professionals post‐surgery. This information influenced behaviours including deciding to undergo surgery, use of pain medication and returning to usual activity. Anxiety and help‐seeking resulted when unexpected post‐surgical events occurred such as extensive bruising. Findings were consistent with psychological and sociological theories. Overall, participants were positive about the information and instruction they received but expressed a desire for more timely information on post‐operative adverse events. PMID:19236631

Prosthetic meshes are used as the standard of care in abdominal wall hernia repair. However, hernia recurrences and side effects remain unsolved problems. The demand by health care providers for increasingly efficient and cost-effective surgery encourages the development of newer strategies to improve devices and outcomes. Here, we evaluated whether l-arginine administration was able to ameliorate long-term polypropylene prostheses incorporation into the abdominal wall of Sprague-Dawley rats. Meshes were placed on-lay and continuous l-arginine was administered. In vivo biocompatibility was studied at 7, 25 and 30 days post-implantation. Effectively, l-arginine administration in combination with mesh triggered subtle changes in ECM composition that impinged on critical biochemical and structural features. Lastly, tensile strength augmented and stiffness decreased over the control condition. This could help to restructure the mechanical load transfer from the implant to the brittle surrounding tissues, i.e., impact load and fatigue load associated with mechanical tensions could be distributed between the mesh and the restored tissue in a more balanced manner, and ultimately help to reduce the incidence of loosening, recurrences, and local wound complications. Since the newly formed tissue is more mechanically stable, this approach could eventually be introduced to human hernia repair.

Inguinal hernias are rare in females. The authors report a case of bilateral inguinal hernias in a 10-year-old female. On exploration, the patient was found to be having a sliding hernia containing incarcerated ovary as contents on both sides. Peroperatively the contents were reduced, the sac was transfixed at its base and the redundant sac was excised. The repair of this form of hernias is more difficult because of adhesions between the contents and the wall of the sac and risk of damage during dissection. A description of this clinical presentation in the pre operative assessment and operative management are discussed in this report. PMID:25918632

The objective of this study was to test the hypothesis that platelet-rich plasma (PRP) pretreatment on a poly-lactic-co-glycolic acid (PLGA) mesh scaffold enhances the healing capacity of the meniscus with human chondrocyte-seeded scaffolds in vivo, even when the seeded number of cells was reduced from 10 million to one million. A flexible PLGA mesh scaffold was pretreated with PRP using a centrifugal technique. One million human articular chondrocytes were seeded onto the scaffold by dynamic oscillation. After 7 days, scaffolds were placed between human meniscal discs and were implanted subcutaneously in nude mice for 6 weeks (n = 16/group). Fluorescence microscopy demonstrated uniform attachment of the chondrocytes throughout the scaffolds 24 h following seeding. Cell attachment analysis revealed a significantly increased number of chondrocytes on PRP-pretreated than non-treated scaffolds (p < 0.05). Field emission scanning electron microscopy revealed chondrocytes attached to the PRP-pretreated scaffolds interconnecting their cellular processes with the fibrin network at 24 h and day 7 of culture. Of the 16 constructs containing PRP-pretreated scaffolds implanted in mice, six menisci healed completely, nine healed incompletely and one did not heal. Histological results from the 16 control constructs containing non-treated scaffolds revealed that none had healed completely, four healed incompletely and 12 did not heal. The histological outcome between the groups was significantly different (p < 0.05). These findings suggest that human articular chondrocytes on PRP-pretreated PLGA mesh scaffolds demonstrate increased cell attachment and enhance the healing capacity of meniscus with a reduced number of seeding cells in a meniscal repair mouse model.

Oggetto di questa pubblicazione è la descrizione di una nuova tecnica chirurgica per la riparazione videolaparoscopica di laparoceli ed ernie della parete addominale anteriore. Tale tecnica è strettamente dipendente dall’utilizzo di un nuovo strumento pneumatico per il posizionamento della protesi. Attualmente esistono in commercio svariati tipi di protesi intraperitoneali con valide caratteristiche strutturali. Tuttavia lo scoglio concettuale rimane sui metodi e sui mezzi di fissaggio delle protesi. I mezzi meccanici di qualsiasi conformazione per il fatto stesso di essere dei mezzi meccanici (spirali metalliche ancorette e viti) espongono al pericolo di danno iatrogeno le strutture vascolari nervose che possono incontrare nel loro percorso. La nuova tecnica proposta mira alla perfetta distensione delle protesi per utilizzo intraperitoneale ed ai loro ottimale fissaggio con adesivo chirurgico in condizioni di sicurezza per le strutture circostanti. Tale tecnica è stata eseguita su cadavere di suino* con protesi intraperitoneali di poliestere-gel-collageno e cyanoacrylate come adesivo chirurgico ma non è esclusa la fattibilità con altri tipi di colle, di protesi, protesi auto-adesive già esistenti in commercio o che potrebbero essere appositamente prodotte.

Purpose Tacks and sutures ensure a strong fixation of meshes, but they can be associated with pain and discomfort. Less invasive methods are now available. Three fixation modalities were compared: the ProGrip™ laparoscopic self-fixating mesh; the fibrin glue Tisseel™ with Bard™ Soft Mesh; and the SorbaFix™ absorbable fixation system with Bard™ Soft Mesh. Materials and methods Meshes (6 cm ×6 cm) were implanted in the preperitoneal space of swine. Samples were explanted 24 hours after surgery. Centered defects were created, and samples (either ten or eleven per fixation type) were loaded in a pressure chamber. For each sample, the pressure, the mesh displacement through the defect, and the measurements of the contact area were recorded. Results At all pressures tested, the ProGrip™ laparoscopic self-fixating mesh both exhibited a significantly lower displacement through the defect and retained a significantly higher percentage of its initial contact area than either the Bard™ Soft Mesh with Tisseel™ system or the Bard™ Soft Mesh with SorbaFix™ absorbable fixation system. Dislocations occurred with the Bard™ Soft Mesh with Tisseel™ system and with the Bard™ Soft Mesh with SorbaFix™ absorbable fixation system at physiological pressure (,225 mmHg). No dislocation was recorded for the ProGrip™ laparoscopic self-fixating mesh. Conclusion At 24 hours after implantation, the mechanical fixation of the ProGrip™ laparoscopic self-fixating mesh was found to be significantly better than the fixation of the Tisseel™ system or the SorbaFix™ absorbable fixation system.

Magnetic resonance (MR) imaging technique and findings in the setting of athletic pubalgia, including injury at the rectus abdominis/adductor aponeurosis, are becoming widely recognized. A subset of these patients is treated with various pelvic floor repairs, mesh reinforcements, and tendon releases. Most of these patients do well after intervention, but some have persistent or refractory groin pain, and others eventually develop new injuries in the pubic region or elsewhere about the pelvic girdle. This review describes the expected and some unexpected MRI findings in patients with recurrent or persistent groin pain after a "sports hernia" repair.

A total of 798 pediatric patients between the ages of 16 days and 10 years underwent a randomized trial of two surgical procedures to assess the superiority of one over the other. In the first group of 231 patients, 236 hernial sacs (HS)/processus vaginalis (PV) were excised completely after transfixation and transection of the sac at the internal ring, whereas in the second group of 567 patients, 595 residual HS/PV were not excised but split longitudinally. The results showed that there was no significant difference in the two groups as far as complications were concerned. Considering the results of these two procedures, it could be concluded that even the less extensive process of distal longitudinal splitting of the residual HS or PV can be preferred in the repair of hernias or communicating hydroceles in male children.

Trocar site hernias are rare complications after laparoscopic surgery but most commonly occur at larger trocar sites placed at the umbilicus. With increased utilization of the laparoscopic approach the incidence of trocar site hernia is increasing. We report a case of a trocar site hernia following an otherwise uncomplicated robotic prostatectomy at a 12 mm right lower quadrant port. The vermiform appendix was incarcerated within the trocar site hernia. Subsequent appendectomy and primary repair of the hernia were performed without complication. PMID:27648335
Background Inguinal hernia repair remains the commonest operation performed by general surgeons all over the world. There is paucity of published data on surgical management of inguinal hernias in our environment. This study is intended to describe our own experiences in the surgical management of inguinal hernias and compare our results with that reported in literature. Methods A descriptive prospective study was conducted at Bugando Medical Centre in northwestern Tanzania. Ethical approval to conduct the study was obtained from relevant authorities before the commencement of the study. Statistical data analysis was done using SPSS software version 17.0. Results A total of 452 patients with inguinal hernias were enrolled in the study. The median age of patients was 36 years (range 3 months to 78 years). Males outnumbered females by a ratio of 36.7:1. This gender deference was statistically significant (P = 0.003). Most patients (44.7%) presented late (more than five years of onset of hernia). Inguinoscrotal hernia (66.8%) was the commonest presentation. At presentation, 208 (46.0%) patients had reducible hernia, 110 (24.3%) had irreducible hernia, 84 (18.6%) and 50(11.1%) patients had obstructed and strangulated hernias respectively. The majority of patients (53.1%) had right sided inguinal hernia with a right-to-left ratio of 2.1: 1. Ninety-two (20.4%) patients had bilateral inguinal hernias. 296 (65.5%) patients had indirect hernia, 102 (22.6%) had direct hernia and 54 (11.9%) had both indirect and direct types (pantaloon hernia). All patients in this study underwent open herniorrhaphy. The majority of patients (61.5%) underwent elective herniorrhaphy under spinal anaesthesia (69.2%). Local anaesthesia was used in only 1.1% of cases. Bowel resection was required in 15.9% of patients. Modified Bassini’s repair (79.9%) was the most common technique of posterior wall repair of the inguinal canal. Lichtenstein mesh repair was used in only one (0.2%) patient

Sebbene la tecnica Mesh Plug rappresenti una procedura di indubbia efficacia nel trattamento dell’ernia inguinale, tuttora permangono dubbi in relazione alla storia naturale del plug. In particolare, il plug può andare incontro a coartazione (shrinkage) con formazione di un “meshoma” responsabile di una sintomatologia dolorosa cronica. Più raramente, il plug può migrare e provocare erosione delle strutture anatomiche circostanti. Nel passato sono stati proposti alcuni devices per cercare di risolvere il problema della migrazione; nessuno di questi, tuttavia, ha raggiunto la popolarità dei plug conici o a forma di fiore. Il presente lavoro riporta i risultati di uno studio pilota condotto con l’impiego di un nuovo device tridimensionale, il NeT Plug & Patch. I risultati dopo 12 mesi di follow-up, hanno dimostrato una ridotta incidenza di dolore postoperatorio e cronico, senza rischio di migrazione. Inoltre è stata registrata una compliance soddisfacente sia dei pazienti che degli operatori. La protesi NeT Plug & Patch ha dimostrato di poter realizzare un’ernioplastica semplice ed efficace per la riparazione dell’ernia inguinale.

Acute umbilical hernia rupture in patients with hepatic cirrhosis and ascites is an unusual, but potentially life-threatening complication, with postoperative morbidity about 70% and mortality between 60%-80% after supportive care and 6%-20% after urgent surgical repair. Management options include primary surgical repair with or without concomitant portal venous system decompression for the control of the ascites. We present a retrospective analysis of our centre’s experience over the last 6 years. Our cohort consisted of 11 consecutive patients (median age: 53 years, range: 36-63 years) with advanced hepatic cirrhosis and refractory ascites. Appropriate patient resuscitation and optimisation with intravenous fluids, prophylactic antibiotics and local measures was instituted. One failed attempt for conservative management was followed by a successful primary repair. In all cases, with one exception, a primary repair with non-absorbable Nylon, interrupted sutures, without mesh, was performed. The perioperative complication rate was 25% and the recurrence rate 8.3%. No mortality was recorded. Median length of hospital stay was 14 d (range: 4-31 d). Based on our experience, the management of ruptured umbilical hernias in patients with advanced hepatic cirrhosis and refractory ascites is feasible without the use of transjugular intrahepatic portosystemic shunt routinely in the preoperative period, provided that meticulous patient optimisation is performed.

The use of synthetic polypropylene mesh for hernia surgical repair and the correction of female pelvic organ prolapse have been controversial due to increasing post-operative complications, including mesh erosion, chronic pain, infection and support failure. These morbidities may be related to a mismatch of mechanical properties between soft tissues and the mesh. The aim of this study was to gain a better understanding of the biomechanical behavior of Prolene polypropylene mesh (Ethicon, Sommerville, NJ, USA), which is widely used for a variety of surgical repair procedures. The stiffness and permanent deformation of Prolene mesh were compared in different directions by performing uniaxial tensile failure tests, cyclic and creep tests at simulated physiological loads in the coursewise (0°), walewise (90°) and the diagonal (45°) directions. Failure tests suggest that the mechanical properties of the mesh is anisotropic; with response at 0° being the most compliant while 90° was the stiffest. Irreversible deformation and viscoelastic behavior were observed in both cyclic and creep tests. The anisotropic property may be relevant to the placement of mesh in surgery to maximize long term mesh performance. The considerable permanent deformation may be associated with an increased risk of post-operative support failure.

Background: Intraperitoneal onlay meshes (IPOM) can be associated with intestine-to-mesh adhesion formation, implementing risks like pain, enterocutaneous fistula, infection, and female infertility. This study investigates, whether a treatment of impaired intestinum with the anti-adhesive and hemostyptic agent 4DryField® PH prevents adhesion formation. Methods: In 20 male LEWIS rats uncoated polypropylene meshes were sewn to the inner abdominal wall and the cecum of the respective animal was de-peritonealized by peritoneal abrasion by a gauze swap, and meso-sutures ensured a constant contact of injured areas. Rats were treated with 4DryField® PH gel either premixed or applied as a powder with in-situ transformation (100 mg powder plus 0.4 ml 0.9% saline solution). One week postoperatively, the extent of intestine-to-mesh adhesions and the quality of mesh ingrowth were evaluated macroscopically by two independent investigators using two scoring systems. Furthermore, specimens were analysed microscopically. All data were compared with control animals without 4DryField® PH treatment and analysed statistically using student’s t-test. Results: Treatment of de-peritonealised cecum with 4DryField® PH significantly reduced intestine-to-mesh adhesions in both treatment groups as compared to controls without 4DryField® PH treatment (68% reduction with premixed gel, P<0.0001; 80% reduction with in-situ gel, P<0.0001). There was no impact on the quality of mesh ingrowth, confirmed histologically by a single-layer mesothelial coverage. Conclusion: These experiments mimick clinical IPOM implantation scenarios with adjacent bowel depleted from peritoneum. 4DryField® PH gel treatment resulted in intestinal mesothelial surface recovering without development of bowel-to-mesh adhesions. Concurrently, integration of mesh into the abdominal wall is undisturbed by 4DryField® PH treatment. PMID:28078041

Background and Objectives: Single-incision laparoscopic surgery is gaining popularity among minimally invasive surgeons and is now being applied to a broad number of surgical procedures. Although this technique uses only 1 port, the diameter of the incision is larger than in standard laparoscopic surgery. The long-term incidence of port-site hernias after single-incision laparoscopic surgery has yet to be determined. Methods: All patients who underwent a single-incision laparoscopic surgical procedure from May 2008 through May 2009 were included in the study. Single-incision laparoscopic surgical operations were performed either by a multiport technique or with a 3-trocar single-incision laparoscopic surgery port. The patients were seen at 30 to 36 months' follow-up, at which time they were examined for any evidence of port-site incisional hernia. Patients found to have hernias on clinical examination underwent repairs with mesh. Results: A total of 211 patients met the criteria for inclusion in the study. The types of operations included were cholecystectomy, appendectomy, sleeve gastrectomy, gastric banding, Nissen fundoplication, colectomy, and gastrojejunostomy. We found a port-site hernia rate of 2.9% at 30 to 36 months' follow-up. Conclusion: Port-site incisional hernia after single-incision laparoscopic surgical procedures remains a major setback for patients. The true incidence remains largely unknown because most patients are asymptomatic and therefore do not seek surgical aid. PMID:24960483

Purpose The relationship between body mass index (BMI) and the risk of inguinal hernia development is unclear. To explore the relationship, we determined whether the incidence of inguinal hernia repairs (IHR) varied across patients in different BMI categories. Study Design A population-based incidence study was undertaken. We reviewed all IHR performed on adult residents of Olmsted County, MN from 2004 to 2008. Cases were ascertained through the Rochester Epidemiology Project, a records-linkage system with more than 97% population coverage. Results During the study period, a total of 1,168 IHR were performed on 879 men and 107 women. The median BMI of the cohort was 26.7 kg/m2 (range 14.9 – 58.1; interquartile range 23.9 – 28.9). Incidence rates varied significantly as a function of BMI (p<0.001). Rates were highest among men who were either normal weight or overweight (419.8 and 421.1 per 100,000 person years for BMI<25 and BMI 25–29.9, respectively), and lowest for obese and morbidly obese men (273.5 and 99.4 per 100,000 person years for BMI 30–34.9 and BMI ≥35, respectively). Findings were similar across all age categories and in patients who had an IHR that was initial or recurrent, direct or indirect, and unilateral or bilateral. Conclusions The incidence of IHR decreased as BMI increased. Obese and morbidly obese patients had a lower incidence of IHR than those who were normal weight or overweight. The causal mechanisms leading to such a relationship are unclear and warrant further study. PMID:24233340

Purpose: Dislocation of the mesh is 1 cause of recurrence after laparoscopic inguinal hernia repair (LIHR). Here, we propose a new procedure, the “preperitoneal cavity suction technique,” to confirm mesh position during LIHR under a transabdominal preperitoneal approach (TAPP). Patients and Methods: We developed the “preperitoneal cavity suction technique” during LIHR by TAPP, visualizing the mesh through the closed peritoneum by vacuuming up the carbon dioxide and effusion at the preperitoneal cavity using a suction tube inserted through the tunnel from a laterally placed trocar into the preperitoneal space. We applied this technique in adults with inguinal hernias who were scheduled to undergo elective surgery in our hospital between April 2013 and March 2015. Results: In total, 84 lesions were treated in 74 consecutive LIHRs by TAPP. The “preperitoneal cavity suction technique” was applied to 83 lesions. We confirmed appropriate positioning of the mesh for 82 of the 83 lesions (98.8%), with dislocation of the mesh detected in 1 case. In that case, we reopened the peritoneal flap and repositioned the mesh correctly during the operation. No patients complained of pain or a sense of discomfort, and no hematoma was identified around the dissected area or anterior superior iliac spine on the affected side. Mean duration of hospitalization was 2.5 days. No cases of hernia recurrence were observed during follow-up (range, 7 to 31 mo; median, 15 mo). Conclusions: The “preperitoneal suction technique” seems useful to detect mesh dislocation and has potential to reduce TAPP-related complications. PMID:27870783

The aim of this prospective study was to set up and evaluate a technique allowing, by the mean of a memory ring, easy placement of the patch in the preperitoneal space (PPS), directly via the hernia orifice, so as to associate the advantages of the preperitoneal patch, anterior approach and minimally invasive surgery. The memory-ring patch was made by basting a PDS cord around a 14 x 7.5 cm oval shaped polypropylene mesh. The hernia sac was dissected, blunt dissection of the PPS was carried out through the hernia orifice and the patch was introduced in the PPS via the orifice. Spreading of the patch in the PPS was facilitated by the memory-ring. One hundred and twenty nine hernias, classified as Nyhus Type IIIa, IIIb and IV, were operated on 126 patients; 11 were big pantaloon or sliding hernias. The anesthesia was spinal in 116 cases and local in 10 cases. There were three benign postoperative complications (2.3%) related to the hernia repair. Ninety six percent of the patients were evaluated with a mean follow up of 24.5 months (12-42). Two recurrences (1.6%) occurred, 7 patients (5.6%) felt some degree of light pain, but not any case of disabling pain was observed. This technique offers many advantages. It is tension-free and almost sutureless. The patch is placed in the PPS through the hernia orifice without any remote opening in the abdominal wall. The patch applied directly to the deep surface of the fascia reinforces the weak inguinal area by restoring the normal anatomic disposition. The good preliminary results are encouraging and justify further randomized evaluation.

Background: Food and Drug Administration announcements have highlighted the standard rate of mesh-related complications. We aimed to report the short-term results and complications of tension-free polypropylene mesh (PROSIMA™) surgical repair of pelvic organ prolapse (POP) using the standard category (C), timing (T), and site (S) classification system. Methods: A prospective cohort study of 48 patients who underwent PROSIMA™ mesh kit-related surgical repairs were followed for two years at Peking Union Medical College Hospital. Recurrence was defined as symptomatic POP quantification (POP-Q) Stage II or higher (leading edge ≥ −1 cm). The Patient Global Impression of Change Questionnaire, the Chinese version of the Pelvic Floor Impact Questionnaire short-form-7 and POP/Urinary Incontinence Sexual Questionnaire short-form-12 were used to evaluate the self-perception and sexual function of each patient. Mesh-related complications conformed to the International Urogynecological Association/International Continence Society joint terminology. The paired-sample t-test, one-way analysis of variance, Fisher's exact test, Kaplan-Meier survival analysis and log-rank test were used to analyze data. Results: All patients were followed up for ≥12 months; 30 (62.5%) patients completed the 24 months study. We observed a 93.8% (45/48) positive anatomical outcome rate at 12 months and 90.0% (27/30) at 24 months. Recurrence most frequently involved the anterior compartment (P < 0.05). Pelvic symptoms improved significantly from baseline (P < 0.05), although the patients’ impressions of change and sexual function were not satisfying. Vaginal complication was the main complication observed (35.4%, 17/48). The survival analysis did not identify any relationship between vaginal complication and anatomical recurrent prolapse (POP-Q ≥ Stage II) (P = 0.653). Conclusions: Tension-free polypropylene mesh (PROSIMA™)-related surgical repair of POP has better short-term anatomical

BACKGROUND Although synthetic mesh is associated with superior anatomic outcomes for the repair of pelvic organ prolapse, the benefits of mesh have been questioned because of the relatively high complication rates. To date, the mechanisms that result in such complications are poorly understood, yet the textile characteristics of mesh products are believed to play an important role. Interestingly, the pore diameter of synthetic mesh has been shown to impact the host response after hernia repair greatly, and such findings have served as design criteria for prolapse meshes, with larger pores viewed as more favorable. Although pore size and porosity are well-characterized before implantation, the changes in these textile properties after implantation are unclear; the application of mechanical forces has the potential to greatly alter pore geometries in vivo. Understanding the impact of mechanical loading on the textile properties of mesh is essential for the development of more effective devices for prolapse repair. OBJECTIVE The objective of this study was to determine the effect of tensile loading and pore orientation on mesh porosity and pore dimensions. STUDY DESIGN In this study, the porosity and pore diameter of 4 currently available prolapse meshes were examined in response to uniaxial tensile loads of 0.1, 5, and 10 N while mimicking clinical loading conditions. The textile properties were compared with those observed for the unloaded mesh. Meshes included Gynemesh PS (Ethicon, Somerville, NJ), UltraPro (Artisyn; Ethicon), Restorelle (Coloplast, Minneapolis, MN), and Alyte Y-mesh (Bard, Covington, GA). In addition to the various pore geometries, 3 orientations of Restorelle (0-, 5-, 45-degree offset) and 2 orientations of UltraPro (0-, 90-degree offset) were examined. RESULTS In response to uniaxial loading, both porosity and pore diameter dramatically decreased for most mesh products. The application of 5 N led to reductions in porosity for nearly all groups

Paraesophageal hiatus hernia can be a morbid and even lethal condition. Although many complications from this entity have been described, they almost always involve gastric incarceration and its related complications. Occasionally, the transverse colon or spleen may be involved in the hernia, causing additional symptoms. An unusual case of paraesophageal hiatus hernia involving incarceration of the pylorus, proximal duodenum, and pancreatic head is described. The patient's presentation, operative management, and perioperative course are discussed to emphasize the importance of early elective repair of paraesophageal hiatus hernia before the development of such occurrences.

In congenital diaphragmatic hernia (CDH), lung hypoplasia and secondary pulmonary hypertension are the major causes of death and severe disability. Based on new therapeutic strategies survival rates could be improved to up to 80%. However, after surgical repair of CDH, long-term follow-up of these pediatric patients is necessary. In this, dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) provides insights into the pulmonary microcirculation and might become a tool within the routine follow-up program of CDH patients. However, whole lung segmentation from DCE-MRI scans is tedious and automated procedures are warranted. Therefore, in this study, an approach to semi-automated lung segmentation is presented. Segmentation of the lung is obtained by calculating the cross correlation and the area under curve between all voxels in the data set and a reference region-of-interest (ROI), here the arterial input function (AIF). By applying an upper and lower threshold to the obtained maps and intersecting these, a final segmentation is reached. This approach was tested on twelve DCE-MRI data sets of 2-year old children after CDH repair. Segmentation accuracy was evaluated by comparing obtained automatic segmentations to manual delineations using the Dice overlap measure. Optimal thresholds for the cross correlation were 0.5/0.95 and 0.1/0.5 for the area under curve, respectively. The ipsilateral (left) lung showed reduced segmentation accuracy compared to the contralateral (right) lung. Average processing time was about 1.4s per data set. Average Dice score was 0.7±0.1 for the whole lung. In conclusion, initial results are promising. By our approach, whole lung segmentation is possible and a rapid evaluation of whole lung perfusion becomes possible. This might allow for a more detailed analysis of lung hypoplasia of children after CDH.

We present a case of a 20-year-old female who was admitted to our department for an elective inguinal hernia repair. An oval-shaped mass was found in the hernia sac during the surgery that was suspected to be an ovary. Histological examination revealed testicular tissue. Further evaluation confirmed testicular feminization. She underwent laparoscopic orchiectomy and hernia repair from the contralateral side 3 months later.

Inguinal hernias involving the ureter, a retroperitoneal structure, is an uncommon phenomenon. It can occur with or without obstructive uropathy, the latter posing a trap for the unassuming general surgeon performing a routine inguinal hernia repair. Ureteral inguinal hernia should be included as a differential when a clinical inguinal hernia is diagnosed concurrently with unexplained hydronephrosis, renal failure or urinary tract infection particularly in a male. The present case describes a patient with a known ureteroinguinal hernia who proceeded to having a planned hernia repair and ureteric protection. The case is a reminder that when faced with an unexpected finding such an indirect sliding inguinal hernia, extreme care should be taken to ensure that no structures are inadvertently damaged and that a rare possibility is the entrapment of the ureter in the inguinal canal.

The aim of the work was to present clinical material referring to rarely occurring abdominal cavity hernias in semilunar line – Spigelian hernias diagnosed with the help of ultrasound. Material and methods In the period from 1995 to 2001 785 anterior abdominal wall hernias were diagnosed including 11 Spigelian hernias (1.4%) diagnosed in 10 patients (7 women and 3 men) aged from 38 to 65 years old (average age 48). Eight patients complained of spastic pain in abdomen, in 5 of them it was accompanied by bloating and sometimes loud peristalsis. All the patients had been observing the mentioned symptoms from 2 to 5 years. Each of them had had colonoscopy and abdominal cavity ultrasound examination performed, some of them even three times. In 3 women with uterine fibroid the uterus was removed which did not eliminate the symptoms. The ultrasound examination of the abdominal integument was performed mainly with the use of linear transducers of the frequency of 7–12 MHz; in obese patients also convex transducers were used (3,5–6 MHz). Each examination of abdominal integument included the assessment of the following areas: linea alba from xiphoid process to pubic symphysis including umbilicus, both semilunar lines from costal margins to pubic bones, and also inguinal areas. Moreover, all types of postoperative scars were examined. Each hernia was assessed in terms of size (the greatest dimension), hernia sac contents, width of the ring and reducibility under the compression of the transducer. Moreover, cough test and Valsalva's maneuver were performed. Generally, the examination was performed in a standing position. Results In 9 patients hernias were localized unilaterally, in one patient bilaterally. In 7 cases the hernia sac contained small bowel, in 2 cases the preperitoneal and omental fat, and in 2 cases preperitoneal fat only. Eight patients presenting with clinical symptoms underwent operative repair. Conclusion Ultrasound examination is beneficial in

The majority of inguinal hernias that are concomitant with abdominal aortic aneurysms (AAA) are clinically insignificant. However, management of AAA associated with a complex hernia can be challenging. We report a case of a 72-year-old male with a 7 cm AAA and a massive inguinal hernia involving loss of abdominal domain. Using a multidisciplinary approach, a staged hybrid endovascular and open repair of the AAA was performed followed by hernia repair.

The iliac crest has become an often used site for autogenous bone graft, because of the easy access it affords. One of the less common complications that can occur after removal is a graft-site hernia. It was first reported in 1945 (see the work by Oldfield, 1945). We report a case of iliac crest bone hernia in a 53-year-old male who was admitted for elective resection of a pseudarthrosis and reconstruction of the left femur with iliac crest bone from the right side. One and a half months after initial surgery, the patient presented with increasing abdominal pain and signs of bowel obstruction. A CT scan of the abdominal cavity showed an obstruction of the small bowel caused by the bone defect of the right iliac crest. A laparoscopy showed a herniation of the small bowel. Due to collateral vessels of the peritoneum caused by portal hypertension, an IPOM (intraperitoneal onlay-mesh) occlusion could not be performed. We performed a conventional ventral hernia repair with an onlay mesh. The recovery was uneventful. PMID:22084778

Fifty-three cases of ventral hernia admitted between 15th July, 1993 and 31st December, 2001 in the IPGME&R, Kolkata is being presented with analysis of causes, method of repair and complications. The study was intended to find a simple, universal cost-effective repair of the deformity. Most cases can be repaired with a method of closure consisting of plication of the inner layer and 2 to 3 layered darning in the outer layer with '0' prolene. The main factor appears to be a tensionless closure and avoidance of postoperative infection and stress like cough and constipation. While in the west, use of prolene mesh has become a routine, the authors feel that darning is not only less expensive but reduces the amount of foreign body introduced.

A diaphragmatic hernia is the protrusion of abdominal contents into the thoracic cavity, via a hole in the diaphragm, which either presence or size is abnormal. Congenital hernias are rare and often diagnosed at birth. Adults are diagnosed accidentally. Symptoms can be digestive or respiratory, and the risk of volvulus calls for surgery. Diaphragmatic ruptures are seen more often, and are a consequence of violent thoraco-abdominal trauma, or penetrating wound. They should be treated surgically in emergency, but the operation can be delayed if they are not diagnosed at once. Videosurgery has been used more and more often recently to treat diaphragmatic hernias.

Epigastric hernia is a common condition, mostly asymptomatic although sometimes their unusual clinical presentation still represents a diagnostic dilemma for clinician. The theory of extra tension in the epigastric region by the diaphragm is the most likely theory of epigastric hernia formation. A detailed history and clinical examination in our thin, elderly male patient who presented with abdominal pain and constipation of 5 days of evolution was crucial in establishing a diagnosis. Noninvasive radiologic modalities such as ultrasonographic studies in the case of our patient can reliably confirm the diagnosis of epigastric hernia.

Morgagni hernia is an unusual congenital herniation of abdominal content through the triangular parasternal gaps of the anterior diaphragm. They are commonly asymptomatic and right-sided. We present a case of a bilateral Morgagni hernia resulting in delayed growth in a 10-month-old boy. The presentation was unique due to its bilateral nature and its symptomatic compression of the mediastinum. Diagnosis was made by 3D reconstructed CT angiogram. The patient underwent medical optimization until he was safely able to tolerate laparoscopic surgical repair of his hernia. Upon laparoscopy, the CT findings were confirmed and the hernia was repaired. PMID:27403367

Background: Numerous classifications for groin and ventral hernias have been proposed over the past five to six decades. The old, simple classification of groin hernia in to direct, inguinal and femoral components is no longer adequate to understand the complex pathophysiology and management of these hernias. The most commonly followed classification for ventral hernias divide them into congenital, acquired, incisional and traumatic, which also does not convey any information regarding the predicted level of difficulty. Aim: All the previous classification systems were based on open hernia repairs and have their own fallacies particularly for uncommon hernias that cannot be classified in these systems. With the advent of laparoscopic/ endoscopic approach, surgical access to the hernia as well as the functional anatomy viewed by the surgeon changed. This change in the surgical approach and functional anatomy opened the doors for newer classifications. The authors have thus proposed a classification system based on the expected level of intraoperative difficulty for endoscopic hernia repair. Classification: In the proposed classification higher grades signify increasing levels of expected intraoperative difficulty. This functional classification grades groin hernias according to the: a) Pre -operative predictive level of difficulty of endoscopic surgery, and b) Intraoperative factors that lead to a difficult repair. Pre operative factors include multiple or pantaloon hernias, recurrent hernias, irreducible and incarcerated hernias. Intraoperative factors include reducibility at operation, degree of descent of the hernial sac and previous hernia repairs. Hernial defects greater than 7 cm in diameter are categorized one grade higher. Conclusion: Though there have been several classification systems for groin or inguinal hernias, none have been described for total classification of all ventral hernias of the abdomen. The system proposed by us includes all abdominal wall

Objectives To evaluate the long-term efficacy and safety of transobturator four-arm mesh for treating cystoceles. Patients and methods In this prospective study, 105 patients had a cystocele corrected between January 2004 and December 2008. All patients had a symptomatic cystocele of stage ⩾2 according to the Baden–Walker halfway stratification. We used only the transobturator four-arm mesh kit (Surgimesh®, Aspide Medical, France). All surgical procedures were carried out by the same experienced surgeon. The patients’ characteristics and surgical variables were recorded prospectively. The anatomical outcome, as measured by a physical examination and postoperative stratification of prolapse, and functional outcome, as assessed by a questionnaire derived from the French equivalents of the Pelvic Floor Distress Inventory, Pelvic Floor Impact Questionnaire and the Pelvic Organ Prolapse–Urinary Incontinence-Sexual Questionnaire, were considered as the primary outcome measures. Peri- and postoperative complications constituted the secondary outcome measures. Results At 36 months after surgery the anatomical success rate (stage 0 or 1) was 93%. On a functional level, all the scores of quality of life and sexuality were improved. The overall satisfaction score (visual analogue scale) was 71.4%. There were no perioperative adverse events. Mesh erosion was reported in 7.6% and mesh retraction in 5.7% of the patients. Conclusions If the guidelines and precautions are followed, vaginal prosthetic surgery for genitourinary prolapse has shown long-term benefits. It provides excellent results both anatomically and functionally. However, complications are not negligible and some are specific to prosthetic surgery. PMID:26019962

Morgagni hernia is a rare type of congenital diaphragmatic hernia. It accounts for only 3% of all diaphragmatic hernias. The defect is small and hernia being asymptomatic in the majority presents late in adulthood. Obstruction or incarceration in Morgagni hernia is uncommon. We report a rare occurrence of strangulated Morgagni hernia. A 40-year-old gentleman presented to our emergency department with features of intestinal obstruction. Computed tomography of the chest and abdomen showed a strangulated right Morgagni hernia. An exploratory laparotomy was performed with resection of the ischemic bowel segment with anastomosis and a primary repair of the diaphragmatic defect. Postoperative recovery was uneventful and asymptomatic at follow-up. PMID:27891284

The management of paraesophageal hernia (PEH) can be challenging due to the lack of consensus regarding indications and principles of operative treatment. In addition, data about the pathophysiology of the hernias are scant. Therefore, the goal of this review is to shed light and describe the classification, pathophysiology, clinical presentation, and indications for treatment of PEHs, and provide an overview of the surgical management and a description of the technical principles of the repair.

A number of new techniques have been studied for managing newborns with congenital diaphragmatic hernia and respiratory insufficiency. Among these have been the techniques of delayed approach to the repair of the diaphragmatic hernia; permissive hypercapnia; nitric oxide and surfactant administration; intratracheal pulmonary ventilation; liquid ventilation; perfluorocarbon-induced lung growth; and lung transplantation. These interventions are at various stages of development and evaluation of effectiveness. All, however, are being explored in the hopes of improving outcome in patients with congenital diaphragmatic hernia who continue to have significant morbidity and mortality in the newborn period.

Ambulatory hernia surgery under local anesthesia is becoming more widely used worldwide. Although many reports include obese patients, there are no studies that report specifically on the feasibility and safety of ambulatory hernia surgery in this category of patients. This paper documents our experience in this respect. The present investigation is an observational study performed at the CRS Hernia Center, Santiago, Chile, on 510 obese and 1,521 non-obese patients with all kinds of hernias susceptible to ambulatory hernia repair under local anesthesia. Both tissue and mesh repairs were performed. Obesity was defined as a body mass index (BMI) greater than 30. Patients with a BMI greater than 45 were excluded from this study. Operative time and pain experienced during the intervention were recorded. During the controls performed by a staff member at the 7th postoperative day, a questionnaire was answered by each patient regarding satisfaction, complaints, and postoperative pain. A second questionnaire was completed on the 30th postoperative day. Satisfaction and pain were both measured by means of a 10-point visual analog scale (VAS). The mean age was similar in both groups (51 years for non-obese and 52 years for obese patients). Obesity was present in 38.3% of women and in 17.5% of men (P < 0.002). Diabetes and hypertension were observed in a significantly (P < 0.004 and P < 0.02, respectively) higher proportion of obese patients. The duration of the operation on obese patients was 78 min compared with 62 min in non-obese patients (P < 0.001). Pain experienced during the intervention was significantly higher in obese patients with a VAS of 2.4 vs. in lean patients with a VAS of 2.0 (P < 0.01). At 24 h, pain was significantly higher and satisfaction significantly lower in obese patients (P < 0.007 and P < 0.0001, respectively). All other parameters were similar in both groups. At 30 days, infection was present in 0.7% of lean patients and in 2.1% of obese patients

The presence of an acutely inflamed vermiform appendix in a femoral hernia sac is extremely rare; the condition is termed De Garengeot's hernia. Here we describe an elderly patient for whom preoperative computed tomography aided the diagnosis of this rare entity. This Chinese woman had presented with a painful right groin mass. The patient successfully underwent an emergency appendicectomy and primary femoral hernia repair. Once diagnosed, it is imperative to follow key surgical principles to limit the spread of infection.

Diaphragmatic hernia was found in a patient who had undergone transhiatal esophagectomy for early esophageal cancer. Chest X-ray was not helpful, but abdominal or chest computed tomography was useful for accurate diagnosis. Primary repair through thoracotomy was performed and was found to be feasible and effective. However, long-term follow-up is required because hernia recurrence is common. PMID:27525243

Intraperitoneal surgical mesh implantation is required for laparoscopic ventral hernia repair. Composite meshes are well known in animal models and human practice. The aim of our study is to compare the biological behaviour of two different textured silicone-covered polypropylene meshes. Transmural abdominal wall defect was created in 40 rabbits and treated as follows: In 20 animals a polypropylene mesh with a laminar silicone covering (LSPP) and in the rest a macroporous textured mesh knitted of silicone-impregnated polypropylene filaments (MSPP) was applied. One and three weeks after implantation we evaluated the intraperitoneal adhesion formation of the mesh macroscopically, histologically and immunohistochemically to detect the reactive cells, especially inflammatory, endothelial and mesothelial cells, as well as their proliferative activity, and with Scanning Electron microscopy to visualize the surface of the meshes. The adhesion formation caused by the composites showed no statistical difference after one week although in the three weeks old samples the LSPP adhesion was significantly weaker than that of MSPP. As complications, serome formation in both groups, fistulas, abscesses, and sc. haematoma in the LSPP group were found. Only in MSPP containing tissues was the decrease of Ki-67 positive proliferating cells significant. A significant increase in VEGF expressing cells was observed only in MSPP containing three week old samples, suggesting better regulation of vascular growth in tissues surrounding the implants. In one week old specimens we observed an irregular proliferation of cytokeratin containing mesothelial cells in both group. The intraperitoneal surface of MSPP mesh was covered with neoperitoneum, while it was not regularly seen on LSPP mesh after three week.

Introduction Formation of adhesions after laparoscopic hernia repair using the intra-peritoneal onlay mesh (IPOM) procedure can lead to intestinal obstruction or mesh erosion into intestinal lumen. The aims of this study included: measurement of adhesion formation with Dynamesh IPOM after laparoscopic intraperitoneal implantation, and assessment of the occurrence of isolated adhesions at the fastening sites of slowly absorbable sutures. Material and methods Twelve healthy pigs underwent laparoscopic implantation of 2 Dynamesh IPOM mesh fragments each, one was fastened with PDSII, and the other with Maxon sutures. An assessment of adhesion formation was carried out after 6 weeks and included an evaluation of surface area, hardness according to the Zhulke scale, and index values. The occurrence of isolated adhesions at slowly absorbable suture fixation points was also analyzed. Results Adhesions were noted in 83.3% of Dynamesh IPOM meshes. Adhesions covered on average 37.7% of the mesh surface with mean hardness 1.46 and index value 78.8. In groups fixed with PDS in comparison to Maxon sutures adhesions covered mean 31.6% vs. 42.5% (p = 0.62) of the mesh surface, mean hardness was 1.67 vs.1.25 (p = 0.34) and index 85.42 vs. 72.02 (p = 0.95). Conclusions The Dynamesh IPOM mesh, in spite of its anti-adhesive layer of PVDF, does not prevent the formation of adhesions. Adhesion hardness, surface area, and index values of the Dynamesh IPOM mesh are close to the mean values of these parameters for other commercially available 2-layer meshes. Slowly absorbable sutures used for fastening did not increase the risk of adhesion formation. PMID:23847671

An inguinoscrotal hernia is a common disorder that usually contains intraperitoneal organs (small intestine, colon, appendix, ovaries). Extraperitoneal ureteral herniation into an inguinoscrotal hernia is a rare condition and often associated with congenital abnormalities or postoperative anatomic changes. A high index of suspicion is needed in order to avoid intraoperative ureteric injuries. We herein report the case of a ureteric herniation into an inguinoscrotal hernia incidentally found during a scheduled hernia repair. PMID:26604607

Poly-4-hydroxybutyrate (P4HB) is a thermoplastic, linear polyester, produced by recombinant fermentation, that can be converted into a wide range of resorbable medical devices. P4HB fibers are exceptionally strong, and can be designed to provide prolonged strength retention in vivo. In 2007, the FDA cleared a monofilament suture made from P4HB for general soft tissue approximation and/or ligation. Subsequently, surgical mesh devices for hernia repair, tendon and ligament repair, and plastic and reconstructive surgery have been introduced for clinical use. This review describes the unique properties of P4HB, its clinical applications, and potential uses that are under development.

Holt-Oram syndrome (HOS) consists of congenital heart disease, usually atrial septal defect, along with thumb anomalies and occasionally more extensive limb defects. Inheritance is autosomal dominant. Previous reports have associated HOS with cytogenetic abnormalities on chromosomes 4, 14 and 20. Recently a linkage study has suggested a HOS locus on chromosome 12. We describe another case of HOS with a de novo cytogenetic abnormality. On prenatal ultrasound, IUGR, oligohydramnios and left diaphragmatic hernia were noted. Following delivery, patient was placed on extra-corporeal membrane oxygenation because of severe lung hypoplasia; diaphragmatic hernia was repaired with mesh graft. He expired on day 17 of life. On exam, he had subtle dysmorphic features with hypotelorism and abnormal folding of the ear lobes. He had bilateral radial aplasia, aplasia of thumbs, index and middle fingers, along with the metacarpals. On autopsy he was found to have atrial septal defect of the ostium secundum type, right side aortic arch with vascular ring formation, bicuspid pulmonic valve and severe lung hypoplasia worse on the left. Cytogenetic analysis on blood and skin showed 48,XX,inv(8)(q24.2q13). Chromosome fragility study was negative. Parental chromosomes were normal. Our observation of inv(8)q with HOS and diaphragmatic hernia may indicate genetic heterogeneity with this condition. Regulation of morphogenesis is likely under the control of a hierarchy of genes; multiple loci for conditions such as HOS would not be surprising.

There are different designs of prosthesis for use in the repair of incisional hernia, and it is often difficult to choose the most appropriate. The biological behaviour of the material must be a key part in the selection, although this behaviour will vary depending on what materials are available. A proper understanding of the relationship of the material with the abdominal wall dynamics is another important factor in this selection. Finally we need a stable repair without long term side effects. This paper analyses the prostheses more commonly available for incisional hernia surgery in the non-emergency situation.

We report a case in which the combination of an interparietal inguinal hernia and ipsilateral ectopic testicle mimicked a spigelian hernia. The patient was a 22-day-old boy who presented with a reducible mass that extended from the right lumbar region to the iliac fossa region. The right testis was palpable in the right lumbar region. Ultrasonography and magnetic resonance imaging revealed that a small bowel had herniated through the inguinal region below the external oblique aponeurosis. Surgery was performed when the patient was 23 months old. Laparoscopic examination to identify the hernia orifice revealed that it was the deep inguinal ring, and the testicular vessels and the vas deferens passed beneath the hernia sac. An inguinal incision was made, and a hernia sac was observed passing through the deep inguinal ring and extending superiorly below the aponeurosis. The testis was found in the hernia sac. Traditional inguinal herniorrhaphy and traditional orchidopexy were performed, and the postoperative course was uneventful. It is difficult to understand the surgical anatomy of interparietal hernias, but once the surgical anatomy is understood, surgical repair is simple. We report the case with a review of the literature and also emphasize that laparoscopic exploration is helpful during surgery.

Spigelian hernia (SH) is an uncommon abdominal wall hernia. Its clinical symptoms are not characteristic, and the preoperative diagnosis is often difficult because SH can simulate the symptoms of more classical lower quadrant abdominal diseases. We report a case of SH in an 80-year-old woman that was complicated by incarceration and diagnosed by physical examination and ultrasound. At the time of presentation, she had an abdominal mass that was soft and occasionally painful, and aggravated by movements that increase intraabdominal pressure. Laparoscopic examination of the abdominal cavity identified the incarcerate jejunum ansae. The defect was a large opening in the peritoneum along the lateral margin of the rectus abdominis muscle. After dissection of the intestinal adhesions, a prosthetic polypropylene mesh was introduced and fixed with staples into the lateral abdominal wall. There were no postoperative complications. We conclude that the laparoscopic approach is a feasible alternative to the conventional open technique that is easy, safe, and allows excellent operative visualization.

This study is aimed at a comprehensive and extensive characterization of the mechanical biocompatibility of mesh prostheses. A robust and simple experimental protocol and a set of parameters is proposed, addressing stiffness under uniaxial and biaxial loading conditions, anisotropy, influence of prior deformation history, local mismatch of deformation mechanisms, and changes in mechanical properties when embedded in a homogeneous matrix. These parameters can form the basis for comparison of different mesh types and for evaluation of their mechanical biocompatibility. Measurements were performed on nine mesh types used for hernia and/or pelvic repair, including heavier as well as lighter implants and covering a wide range of mechanical responses. A total of 93 experiments were performed and all parameters are represented for each mesh in a single diagram to facilitate the quantitative assessment of implant characteristics and their comparison. The mechanics of implants is a critical factor determining clinical performance which should be accounted for in mesh selection and for development of future implants.

Diaphragmatic injuries either by blunt or penetrating trauma require prompt surgical intervention and are often exigent to repair. N-butyl-2-cyanoacrylate (n-butyl-2-CA) is a tissue adhesive which has gained wide application in many areas of surgery including emergency. To repair the extensive injuries of the diaphragm it may be necessary the use of synthetic mesh by fixing it with sutures or staples. The use of tissue adhesives may circumvent the potential problems associated with mesh fixation. This study aimed to evaluate the efficacy and safety of tissue adhesives usage for mesh fixation in diaphragmatic injury repair. Twenty-four rats were divided into 3 groups each of them containing 8 rats. A 1- cm diaphragmatic defect was created in all rats. The defect was repaired by polypropylene suture in Group I, by mesh fixed with sutures in group II and by mesh fixed with n-butyl-2-CA in group III. The rats were sacrificed after 1 month. The episode of hernia and the adhesions were assessed by adhesion density score. Also, the abscess and inflammation in the repaired tissue were evaluated microscopically. The Kruskal-Wallis test was performed for the histopathological analysis. No diaphragmatic hernia was detected in any group. While Group III had higher adhesion density scores than group I (P: 0.027), there were no differences between group III and II (P: 0.317) and group II and I (P = 0.095) regarding adhesion density scores. The inflammation grade was higher in group III than group I and II (P < 0.001) and was higher in group II than group I (P < 0.05). There was no differences between each groups, concerning microabcsess formation (P > 0.05). Repair of traumatic diaphragmatic injury in penetrating wound, with polypropylene mesh fixed by n-butyl-2-CA in rats appears to be as efficacious and safe as conventional methods in early period. However, further experimental and clinical study are needed to compare the long-term results of adhesive mesh repair with those of

Introduction: The existing literature shows that mesh reinforcement improves the anatomical success rate of cystocele repair. We report the long-term results of a custom bell-shaped mesh with simultaneous urethral support for the repair of cystocele. Materials and Methods: The present study was a single-center, single-surgeon case series of 36 patients. Only patients with Pelvic Organ Prolapse Quantification system (POP-Q) stage 2 and above were included in the study. Patients having rectocele or uterine/vault prolapse were excluded. Body of the mesh was used for reinforcement of the cystocele repair and two limbs were left tension free in the retropubic space. Patients were followed 3 monthly for the first year and yearly thereafter. Recurrence was defined as cystocele ≥stage 2 (Aa or Ba 0) any time after the first follow-up. Results: Mean patient age was 58.5 ± 6.2 years. The mean parity was 3.2 ± 1.6. Of 36 patients, 11 (30.5%) of the patients were POPQ stage 2, 15 (41.7%) were stage 3 and 10 (27.7%) were stage 4 cystocele. The mean follow-up period was 53.4 months, with 32 patients reporting for follow-up till date (88.9%). There was no bladder injury, no mesh erosion or infection. No patient required CIC (clean intermittent catheterization) or had stress urinary incontinence post-operatively at 5 years of follow-up. Conclusion: The bell-shaped mesh is a simple, effective and safe procedure in the surgical management of cystocele with excellent long-term outcome. PMID:26604446

INTRODUCTION Internal abdominal hernias are infrequent but an increasing cause of bowel obstruction still often underdiagnosed. Among adults its usual causes are congenital anomalies of intestinal rotation, postsurgical iatrogenic, trauma or infection diseases. PRESENTATION OF CASE We report the case of a 63-year-old woman with history of chronic constipation. The patient was hospitalized for two days with acute abdominal pain, abdominal distension and inability to eliminate flatus. The X-ray and abdominal computerized tomography scan (CT scan) showed signs of intestinal obstruction. Exploratory laparotomy performed revealed a trans-mesenteric hernia containing part of the transverse colon. The intestine was viable and resection was not necessary. Only the hernia was repaired. DISCUSSION Internal trans-mesenteric hernia constitutes a rare type of internal abdominal hernia, corresponding from 0.2 to 0.9% of bowel obstructions. This type carries a high risk of strangulation and even small hernias can be fatal. This complication is specially related to trans-mesenteric hernias as it tends to volvulize. Unfortunately, the clinical diagnosis is rather difficult. CONCLUSION Trans-mesenteric internal abdominal hernia may be asymptomatic for many years because of its nonspecific symptoms. The role of imaging test is relevant but still does not avoid the necessity of exploratory surgery when clinical features are uncertain. PMID:24880799

An 80-year-old woman presented to the emergency department with failure to thrive and weakness for 14 days. Medical history was significant for polio. On admission her electrocardiogram showed atrial flutter, and cardiac enzymes were elevated. Echocardiogram revealed a high pulmonary artery pressure, but no other wall motion abnormalities or valvulopathies. Chest x-ray showed a large lucency likely representing a diaphragmatic hernia. Computed tomographic scan confirmed the hernia. Our patient remained in atrial flutter despite rate control, and thereafter surgery was consulted to evaluate the patient. She underwent hernia repair. After surgery, the patient was taken off rate control and monitored for 72 hours; she did not have any episode of atrial flutter and was discharged with follow up in a week showing no arrhythmia. Her flutter was caused directly by the mechanical effect of the large hiatal hernia pressing against her heart, as the flutter resolved after the operation.

The presence of a vermiform appendix in an inguinal hernia sac is termed as Amyand's hernia. Although rare, mistakes in diagnosis and treatment can cause catastrophic results. Charts of patients with inguinal hernia were reviewed, and four cases of Amyand's hernia were confirmed. The clinical presentation, anesthetic, and perioperative management of Amyand's hernia were further analyzed. The mean age of patients was over 70 years, and all were males. None of the patients were diagnosed preoperatively. All the patients had little abdominal complaint only with a right inguinal mass and dragging sensation for several hours. Due to the short time after incarceration and significant cardiovascular and pulmonary comorbidities, manual reduction was attempted first in three patients. With complete preoperative evaluation and careful perioperative support, all patients underwent appendectomy and Bassini's hernia repair through a groin incision. Based on age-related organ failure and associated chronic medical illnesses of geriatric patients, the difficulties in the diagnosis and treatment are also summarized and analyzed.

There is increasing evidence to show that the use of surgical meshes reduces recurrence rates of hernia repair and anterior vaginal wall prolapse. The aim of this study was to determine the safety and efficacy of posterior colporrhaphy with mesh in patients with posterior vaginal prolapse. An ambispective observational study involving 90 patients was conducted with retrospective chart review and prospective subjective and objective assessments at the end of a 1-year study period. Apart from 2 of 90 (2.2%) minor hematoma incidents, there was no other major perioperative morbidity. Prevalence of common prolapse complaints of vaginal lump sensation, constipation, defecation difficulty and dyspareunia all improved significantly postoperatively (p<0.001). Surgical correction was achieved in 27 of 31 (83.9%) at 6 months and beyond. There was no mesh infection but minor vaginal mesh protrusion was found in 7 of 90 (7.8%) patients at 6-12 weeks and 4 of 31 (12.9%) patients at 6 months and beyond. All these were treated easily with trimming without the need of mesh removal. We conclude that posterior colporrhaphy with mesh is effective in treating posterior vaginal prolapse in short term.

Inguinal hernia was associated with trauma in five dogs and was considered nontraumatic in 30 dogs. There were 11 males, 13 intact females, and six spayed females with nontraumatic inguinal hernia. Six dogs had bilateral hernias. Five dogs were younger than 4 months at the time of diagnosis. In 11 older dogs with nontraumatic inguinal hernia, the hernias were identified less than 7 days before surgical repair; in 14 older dogs, the hernias had been recognized for 1 to 60 months. Clinical signs in dogs without small intestinal incarceration were usually limited to a visible or palpable mass without pain or systemic illness. Herniorrhaphy approaches included inguinal, midline with contralateral ring evaluation, and celiotomy with or without inguinal exposure. Fat and omentum were the most common hernial contents. Small intestine was within the hernias of 12 dogs. Six dogs had nonviable small intestine. Postoperative complications included two incisional infections, one incisional dehiscence, two cases of peritonitis and sepsis associated with bowel leakage after intestinal resection and anastomosis, and one hernia recurrence. The overall prevalence of postoperative complications was 17%, and the mortality rate was 3%. Vomiting for 2 to 6 days was predictive of nonviable small intestine. Dogs younger than 2 years were at 11 times greater risk for nonviable small intestine than dogs older than 2 years. Four of five dogs with nontraumatic inguinal her
