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

From October 1993 to April 1994, laparoscopic ventral hernia repair was performed on 10 patients, all of whom had a history of failed ventral hernia repair and at least two prior ventral hernia repair procedures. Patients presented with complaints of abdominal discomfort, painful mass at the hernia site, or vague abdominal discomfort. No operative deaths occurred. Two patients had minor complications: a seroma at the repair site, which resolved spontaneously, and a superficial wound infection at a trochar site, which responded to an oral cephalosporin. Six patients were discharged within 24 hours of surgery and one patient was operated on as an outpatient and discharged the same day. Follow-up of all patients ranged from 10 to 17 months. No evidence of hernia recurrence has been noted. Some recurrent ventral hernias are amenable to laparoscopic repair, and this technique may be preferable in some patients, especially those who have had an earlier failed open repair with mesh. We do not advocate use of our technique for the first repair of a ventral hernia. Long-term follow-up is still needed to determine recurrence rates compared with conventional open techniques.

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.

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.

Primary ventral hernias and ventral incisional hernias have been a challenge for surgeons throughout the ages. In the current era, incisional hernias have increased in prevalence due to the very high number of laparotomies performed in the 20th century. Even though minimally invasive surgery and hernia repair have evolved rapidly, general surgeons have yet to develop the ideal, standardized method that adequately decreases common postoperative complications, such as wound failure, hernia recurrence and pain. The evolution of laparoscopy and ventral hernia repair will be reviewed, from the rectoscopy of the 4th century to the advent of laparoscopy, from suture repair to the evolution of mesh reinforcement. The nuances of minimally invasive ventral and incisional hernia repair will be summarized, from preoperative considerations to variations in intraoperative practice. New techniques have become increasingly popular, such as primary defect closure, retrorectus mesh placement, and concomitant component separation. The advent of robotics has made some of these repairs more feasible, but only time and well-designed clinical studies will tell if this will be a durable modality for ventral and incisional hernia repair.

Surgical treatment of ventral hernias has changed dramatically over the past decades by the introduction of laparoscopy and prosthetic biomaterials for reinforcement of the abdominal wall. There are many meshes available on the market for laparoscopic ventral hernia repair (LVHR), and new meshes are introduced regularly. Experimental and clinical documentation for safety and efficacy are, however, often not available for the clinician. The choice of mesh may therefore be difficult in clinical practice. We present a review of the current literature regarding safety measures such as adhesions, fistulas, and infections as well as the available data on pain, recurrence, mesh shrinkage, and seroma formation after LVHR. The literature was searched systematically using PubMed/MEDLINE and EMBASE for controlled studies, prospective descriptive series and retrospective case series. The literature clearly points in the direction of very few mesh-related complications after LVHR. Experimental studies and theoretical considerations may argue for using a covered mesh, i.e., a composite mesh, or ePTFE for LVHR in humans, although it is important to stress that there are no human data at the moment to support this. Concerns about using pure polypropylene mesh in the intraperitoneal position may be re-evaluated with the experience of lightweight macropore meshes from open surgery in mind. There is a tendency towards greater shrinkage in ePTFE-based meshes but no differences seems to exist between different mesh materials in other relevant outcome parameters from clinical series. The literature cannot give general recommendations for choice of mesh based on randomized controlled trials. The final choice of mesh for LVHR will therefore typically be based on surgeons' preference and cost while we await further data from randomized controlled clinical trials.

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

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 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.

The aim of the study is to investigate the outcomes of the da Vinci robot-assisted laparoscopic hernia repair of small-sized ventral hernias with circumferential suturing of the mesh compared to the traditional laparoscopic repair with trans-fascial suturing. A retrospective review was conducted of all robot-assisted umbilical, epigastric and incisional hernia repairs performed at our institution between 2013 and 2015 compared to laparoscopic umbilical or epigastric hernia repairs. Patient characteristics, operative details and postoperative complications were collected and analyzed using univariate analysis. Three primary minimally invasive fellowship trained surgeons performed all of the procedures included in the analysis. 72 patients were identified during the study period. 39 patients underwent robot- assisted repair (21 umbilical, 14 epigastric, 4 incisional), and 33 patients laparoscopic repair (27 umbilical, 6 epigastric). Seven had recurrent hernias (robot: 4, laparoscopic: 3). There were no significant differences in preoperative characteristics between the two groups. Average operative time was 156 min for robot-assisted repair and 65 min for laparoscopic repair (p < 0.0001). The average defect size was significantly larger for the robot group [3.07 cm (1-9 cm)] than that for the laparoscopic group [2.02 cm (0.5-5 cm)] (p < 0.0001), although there was no significant difference in the average size of mesh used (13 vs. 13 cm). There was no difference in patients requiring postoperative admission or length of stay between the two groups. The mean duration of follow-up was 47 days. There was no difference in complication rate during this time, and no recurrences were reported. There are no significant differences in terms of safety and early efficacy when comparing small-sized ventral hernias repaired using the robot-assisted technique versus the standard laparoscopic repair.

Supposing divergent aetiology, we found it interesting to investigate outcomes between primary (PH) versus incisional (IH) hernias. In addition, we wanted to analyse the effect of defect closure and mesh fixation techniques. 37 patients with PH and 70 with IH were enrolled in a prospective cohort-study, treated with laparoscopic ventral hernia repair (LVHR) and randomised to ± transfascial sutures. In addition, we analysed results from a retrospective study with 36 PH and 51 IH patients. Mean follow-up time was 38 months in the prospective study and 27 months in the retrospective study. 35 % of PH's and 10 % of IH's were recurrences after previous suture repair. No late infections or mesh removals occurred. Recurrence rates in the prospective study were 0 vs. 4.3 % (p = 0.55) and the complication rates were 16 vs. 27 % (p = 0.24) in favour of the PH cohort. The IH group had a mesh protrusion rate of 13 vs. 5 % in the PH group (p = 0.32), and significantly (p < 0.01) larger hernias and adhesion score, longer operating time (100 vs. 79 min) and admission time (2.8 vs. 1.6 days). Closure of the hernia defect did not influence rate of seroma, pain at 2 months, protrusion or recurrence. An overall increased complication rate was seen after defect closure (OR 3.42; CI 1.25-9.33). With PH, in comparison to IH treated with LVHR, no differences were observed regarding recurrence, protrusion or complication rates. Defect closure (raphe), when using absorbable suture, did not benefit long-term outcomes and caused a higher overall complication rate. (ClinicalTrials.gov number: NCT00455299).

Laparoscopic ventral hernia repair shortens the length of hospital stay and achieves low rates of hernia recurrence. The inherent difficulties of performing advanced laparoscopy operations, however, have limited the adoption of this technique by many surgeons. We hypothesized that the virtual operative field and hand-like instruments of a telerobotic surgical system could overcome these limitations. We present herein the first 2 reported cases of telerobotic laparoscopic ventral hernia repair with mesh. The operations were accomplished with the da Vinci telerobotic surgical system. The hernia defects were repaired with dual-sided, expanded polytetrafluoroethylene (ePTFE) mesh. The mesh was secured in place with 8 sutures that were passed through the abdominal wall, and 5-mm surgical tacks were placed around the circumference of the mesh. The 2 operations were accomplished with total operative times of 120 and 135 minutes and total operating room times of 166 and 180 minutes, respectively. The patients were discharged home on postoperative days 1 and 4. The surgeon sat in an ergonomically comfortable position at a computer console that was remote from the patient. Immersion of the surgeon within the 3-dimensional virtual operative field expedited each stage of these procedures. The articulation of the wristed telerobotic instruments greatly facilitated reaching the anterior abdominal cavity near the abdominal wall. This report indicates that telerobotic laparoscopic ventral hernia repair is feasible and suggests that telepresence technology facilitates this procedure. PMID:12722992

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.

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

Absence of recurrence, seroma, and pain eludes the laparoscopic surgeon managing ventral and incisional hernias. Multifactorial etiology (i.e., obesity, comorbidity, and dyscollagenemia) is a challenge. Surgeons have risen to this challenge by providing laparoscopic ventral hernia repair (LVHR). Stability of mesh in a standard LVHR is attributed to Pascal's Principle (PP). PP, based upon concentration of forces at the point of least resistance, has been classically applied in hydraulic jacks to move large masses. Application of PP in LVHR is thus misplaced where the hernial defect becomes a point of concentration of intra-abdominal forces. This makes the mesh inherently unstable. For a stable mesh aided by PP, benefits of defect closure needed to be explored. Between January 2000 and December 2004, 30 nonsmoker patients with incisional, primary ventral, and recurrent ventral hernias were operated on. Laparoscopic closure of the defect augmented with intraperitoneal onlay mesh (IPOM), as done in standard LVHR, was preformed. Thirty patients with 34 defects of a mean "closed defect" length of 5.7 cm (range, 3-10) were operated on. Mean operative time was 90 minutes (range, 75-110). There were no conversions, visceral injury, postoperative visible bulge, or seroma. No painkiller except Paracetamol was required. There was no recurrence in a mean follow-up of 58 months (range, 26-84). Restored abdominal contour was achieved by all the patients. Closure of hernial defect augmented with IPOM is a safe, patient friendly, and scientific way of doing LVHR.

During the past 2 years 15 laparoscopic ventral hernias have been performed at our Community Hospital. Marlex mesh has been the material used. We have noticed some difficulty with the grasping and initial anchoring of the mesh. Percutaneously placed prolene sutures allow the mesh to be drawn upward with some effort. By using laparoscopic T-bars for the initial anchoring of the mesh to the anterior abdominal wall then stapling, the operative time was greatly reduced. This modification in technique allows for quicker placement of the mesh during the repair.

Although most surgeons report using both transfascial sutures and laparoscopically placed tacks to secure prostheses in laparoscopic ventral hernia repair, a significant minority have reported large series in which sutures were omitted. A systematic review of the available literature was conducted for large case series and controlled trials documenting long-term follow-up. Forty-three articles were identified, including 6015 patients whose prostheses were secured with transfascial sutures (with or without tacks), and 2450 patients receiving tacks or staples alone. The mean follow-up time reported was 30.1 months. No significant difference was found in rates of hernia recurrence, mesh removal, prolonged postoperative pain, patient body mass index, or hernia defect size between the two groups. The suture group did experience a significantly higher rate of surgical site infection. Although suture tensile strength is greater than that of tacks, and despite numerous anecdotal reports of hernia recurrence secondary to suture failure or omission, the existing literature does not show superiority of one mesh fixation technique over the other for recurrence, whereas infection rates increase when transfascial suture is used.

The operative management of complex ventral hernia poses a formidable challenge, despite recent advances in surgical techniques. Recurrence rates after complex ventral hernia repair remain high, and increase with each failed attempt. This study examines the effect of pre-operative abdominal wall chemical component relaxation using Botulinum Toxin A (BTA) to induce temporary flaccid paralysis in order to facilitate laparoscopic repair of large complex ventral hernia. This is a prospective evaluation of 27 patients from January 2013 to August 2015 who underwent ultrasound guided BTA injections to the lateral abdominal wall muscles prior to elective complex ventral hernia repair. Non-contrast serial CT imaging was obtained pre- and post-BTA injection to measure change in fascial defect size and abdominal wall muscle thickness and length. Fascial defects were closed and hernias repaired using laparoscopic or laparoscopic-assisted intra-peritoneal onlay mesh (IPOM) techniques. 27 patients received pre-operative BTA injections which were well tolerated with no complications. Comparison of pre-BTA and post-BTA CT imaging demonstrated a significant increase in mean length of the lateral abdominal wall from 15.7 cm pre-BTA to 19.9 cm post-BTA (p < 0.0001), with mean unstretched length gain of 4.2 cm/side (range 0-11.7 cm/side). All hernias were surgically reduced and repaired with mesh, with no early recurrences. Pre-operative administration of BTA is a safe and effective technique in the pre-operative preparation of patients undergoing elective complex ventral hernia repair. This technique lengthens and relaxes the laterally retracted abdominal muscles and enables laparoscopic closure of large complex ventral hernia.

Postoperative wound dehiscence is a difficult problem for the general surgeon. Often, patients are too sick, or the wound environment is too hostile, to undergo primary repair. When an eventual repair is performed, a variety of methods are available, but most are associated with unacceptably high morbidity rates, specifically high incidences of recurrences and poor cosmetic outcome. We present here a case of postoperative wound dehiscence following a colostomy takedown repaired in a previously undescribed way—a laparoscopically assisted ventral incisional hernia repair. The method of repair is described, and the current literature regarding alternatives is reviewed. PMID:15984722

Operative management of complex ventral hernia still remains a significant challenge for surgeons. Closure of large defects in the unprepared abdomen has serious pathophysiological consequences due to chronic contraction and retraction of the lateral abdominal wall muscles. We report outcomes of 56 consecutive patients who had preoperative Botulinum toxin A (BTA) abdominal wall relaxation facilitating closure and repair. This was a prospective observational study of 56 patients who underwent ultrasound-guided BTA into the lateral abdominal oblique muscles prior to elective ventral hernia repair between November 2012 and January 2017. Serial non-contrast abdominal CT imaging was performed to evaluate changes in lateral oblique muscle length and thickness. All hernias were repaired laparoscopically, or laparoscopic-open-laparoscopic (LOL) using intraperitoneal onlay mesh. 56 patients received BTA injections at predetermined sites to the lateral oblique muscles, which were well tolerated. Mean patient age was 59.7 years, and mean BMI was 30.9 kg/m(2) (range 21.8-54.0). Maximum defect size was 24 × 27 cm. A subset of 18 patients underwent preoperative pneumoperitoneum as an adjunct procedure. A comparison of pre-BTA to post-BTA imaging demonstrated an increase in mean lateral abdominal wall length from 16.1 cm to 20.1 cm per side, a mean gain of 4.0 cm/side (range 1.0-11.7 cm/side) (p < 0.0001). This corresponds to an unstretched mean length gain of 8.0 cm of the lateral abdominal wall. Laparoscopic/LOL primary closure was achieved in all cases, with no clinical evidence of raised intra-abdominal pressures. One patient presented with a new fascial defect 26 months post-operative. Preoperative BTA to the lateral abdominal wall muscles is a safe and effective technique for the preparation of patients prior to operative management of complex ventral hernias. BTA temporary flaccid paralysis relaxes, elongates and thins the chronically contracted abdominal

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.

The aim of this study was to evaluate hernia appearance at the trocar site after laparoscopic treatment of primary or incisional ventral hernias using an intraperitoneal prosthetic mesh. Chronic pain at the trocar site and primary hernia recurrence were also evaluated. Two-hundred and twenty-six consecutive patients who underwent a standardized laparoscopic hernia repair for primary or incisional ventral hernia at our centre between January 2000 and December 2008 were included. All patients had clinical and radiological examinations. Primary end points were port site hernia and the occurrence of chronic trocar site pain. Secondary end point was primary hernia recurrence. Seventy-eight patients were excluded: 6 declined to participate, 48 were unreachable, and 24 did not meet the inclusion criteria (nine underwent a single site laparoscopic approach, ten died of unrelated disease, three were unable to visit the hospital and two had relocated). After exclusion, 148 remained in our study. Mean follow-up was 49 ± 12.6 months. Mean age at the time of surgery was 60 years (range, 28-83) In total, 504 port sites were clinically and radiologically evaluated, and only one (0.02%) had secondary herniation. Three patients (2.0%) had a recurrent hernia, and 14 (9.5%) had developed chronic pain at time of assessment. Nine patients (6.1%) were re-operated for the recurrent hernia before the follow-up evaluation. The overall recurrence rate is, therefore, 8.1%. Only two minor complications and no major complications occurred after surgery. No mortality was observed. Laparoscopic repair for primary or incisional ventral hernias is a safe surgical approach, with low rates of hernia recurrence and a low morbidity rate. When fascial closure is maintained for 10 mm port sites, the incidence of port site hernias is very low. Five millimetre ports do not require closure.

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.

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

Research in computer vision and mobile robotics has developed a family of popular algorithms known as Visual Simultaneous Localization And Mapping (Visual SLAM). These algorithms can provide 3D models of body cavities using the images obtained from standard monocular endoscopes. The 3D models can be used to estimate hernia defect measurements during laparoscopic ventral hernia repair (LVHR). We conducted a descriptive and comparative prospective study to analyze results from 15 patients who underwent LVHR. Three methods of measurement were used in each patient: two classical methods (needle and tape) and a new visual SLAM measurement (VSM) method. The major and minor axes of the ellipse-shaped hernia defect were measured. Both axes could be measured using the VSM method in all patients except one (93%). The tape method measured 63% of the axes, but was difficult to perform because of patient comorbidities and because of limited range of motion of the laparoscopic tools. The needle method obtained 73% of measurements, because of patient comorbidities. The tape method was the most accurate (accuracy up to 0.5 cm because of tape resolution). The needle method was relatively inaccurate, with a mean error of >3 cm. The VSM method was as accurate as the tape method. The mean time taken to perform measurements was 40 s for the VSM method (range 29-60 s), 169 s for the needle method (range 66-300 s), and 186 s for the tape method (range 110-322 s). The needle method is relatively inaccurate and invasive. The tape method is accurate, but is not easy to perform and is relatively time consuming. The VSM method is noninvasive and fast and is as accurate as the tape method.

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.

Laparoscopy, specifically the bridged mesh technique, is a popular means used for ventral hernia repair. While laparoscopy has decreased the incidence of surgical site infection (SSI), hernia recurrence rates remain unchanged. Some surgeons advocate laparoscopic primary fascial closure (PFC) with placement of intraperitoneal mesh to decrease recurrence rates. We hypothesize that in patients undergoing laparoscopic ventral hernia repair (LVHR), PFC compared to a bridged mesh repair decreases hernia recurrence rates. A multicenter, retrospective database of all ventral hernia repairs performed from 2010-2012 was accessed. Patients who underwent LVHR with mesh were reviewed. Patients who had PFC were compared to bridged repair. Primary outcome was hernia recurrence determined by clinical examination or CT scan. Secondary outcomes included SSI and seroma formation. A total of 1594 patients were identified. Following exclusion, a total of 196 patients were left who underwent LVHR with a mean follow-up period of 17.5 months. Ninety-seven patients underwent PFC, while 99 underwent bridged repairs. Initial comparisons between both groups was negative for any significant statistical difference in terms of recurrence, seroma formation, SSI, deep/organ space SSI, reoperation, and readmission. The same initial findings held true during subgroup analysis. Propensity score analysis was then performed for recurrence, seroma, and SSI controlling for age, gender, immune status, ASA class, BMI, smoking status, and acute repair. No statistically significant differences were identified in either group. Primary fascial closure during laparoscopic hernia repairs did not result in reduced recurrence, seroma, and SSI as compared to bridge repairs in a retrospective, multi-institutional study. However, additional research is needed to further evaluate benefits to the patient in terms of pain, function, cosmesis, and overall satisfaction. Randomized, blinded, control trials should focus on

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

There are a variety of different products available for laparoscopic ventral hernia repairs (LVHR), which vary widely in their costs. There are few clinical studies commenting on cost efficacy of LVHR. The objective of this study is to investigate the cost, safety, and efficacy of using intraperitoneal nonheavyweight polypropylene (PP) mesh in LVHR. Between the years 2002 and 2006, LVHR was performed in 141 consecutive patients (84 male, 57 female) using intraperitoneal PP. Using a 3-trocar technique, PP mesh was underlayed by 3 to 5 cm beyond the edges of the hernia defect and fixed to the abdominal wall with 2 rows of titanium staples. Data concerning the demographics of patients, mesh cost, operative time, length of hospital stay, and complications were collected. One hundred thirty-four patients (95%) were discharged on the day of surgery. Mean age was 58.7 years (range, 29 to 91 y). Mean operative time was 63 minutes (range, 34 to 124 min). Follow-up was achieved in 123 patients (87%) with a mean of 40 months (range, 12 to 68 mo). The average mesh size was 256.9 cm (range, 116 to 903 cm). The cost of the PP mesh was US$0.14 per cm. The average mesh cost per patient was $35.90. When compared with other meshes commonly used for LVHR, PP mesh was substantially cheaper with a cost saving of $436 per patient with proceed, $770 per patient with composix, and $931 per patient with polytetrafluoroethylene. The postoperative complications included: Wound infection n=4 (3.2%), transient partial small bowel obstruction which resolved in all cases without operative management n=3 (2.4%), port site hernia n=2 (1.6%), and seroma n=1 (0.7%). Overall recurrence rate was n=6 (4.8%). There were no conversions to an open procedure. LVHR with intraperitoneal PP results in outcomes comparable with earlier publications on LVHR but at reduced costs. These data suggest that the use of intraperitoneal PP in LVHR is safe and cost effective.

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

In an attempt to improve patient outcome and quality of life after laparoscopic ventral hernia repair, resorbable fixation devices have been developed to allow adequate mesh fixation while minimizing accompanying side-effects as tack erosion and adhesion formation. In experimental set-up, 24 pigs were treated by laparoscopic mesh placement. Two different meshes (PP/ORC and PP/ePTFE) and four fixation devices were evaluated: a 6.4 mm poly(D,L: )-lactide pushpin (tack I), a 6.8 mm poly(D,L: )-lactide with blunt tip (tack II), a 4.1 mm poly(glycolide-co-L-lactide) (tack III) and one titanium tack (control tack). A first group of animals (n = 12) was euthanized after 2 weeks survival and a second group (n = 12) after 6 months. At euthanasia, a relaparoscopy was performed to assess adhesion formation followed by laparotomy with excision of the entire abdominal wall. Tensile strength of the individual fixation systems was tested with the use of a tensiometer by measuring the force to pull the tack out of the mesh. Additionally, the foreign body reaction to the fixation systems was evaluated histologically as was their potential degradation. At 2 weeks the tensile strength was significantly higher for the control tack (31.98 N/cm²) compared to the resorbable devices. Except for tack II, the tensile strength was higher when the devices were fixed in a PP/ePTFE mesh compared to the PP/ORC mesh. After 6 months only tack III was completely resorbed, while tack I (9.292 N/cm²) had the lowest tensile strength. At this time-point similar tensile strength was observed for both tack II (29.56 N/cm²) and the control tack (27.77 N/cm²). Adhesions seem to be more depending on the type of mesh, in favor of PP/ePTFE. At long term, the 4.1 mm poly(glycolide-co-L-lactide) tack was the only tack completely resorbed while the 6.8 mm poly(D,L: )-lactide tack with blunt tip reached equal strengths to the permanent tack.

The purpose of this study was to determine whether laparoscopic intraperitoneal polytetrafluoroethylene (PTFE) prosthetic patch (LIPP) repair of a ventral hernia is superior to open prefascial polypropylene mesh (OPPM) repair in a tertiary care university hospital in an urban environment. Data on 39 consecutive patients undergoing either LIPP repair (n = 21) or OPPM repair (n = 18) were compared. Findings showed that LIPP repair is characterized by less painful recovery and shorter hospital stay, with 90% of patients treated successfully as outpatients as compared with 7% in the OPPM group. The total facility costs for the LIPP repair ($8,273+/-$2,950) was significantly lower than for the OPPM repair ($12,461+/-$5,987) (p<0.05). Two serious delayed complications in the LIPP group were treated by reoperation (colocutaneous fistula, mesh infection), but the higher readmission costs in this group did not negate the overall cost advantage for LIPP repair. In the follow-up evaluation, 1 hernia recurrence was found in the LIPP repair group, and none in the OPPM group. Initial experience suggests that LIPP repair has advantages over OPPM repair in terms of decreased hospitalization, postoperative pain, and disability. Refinements in the technique to reduce complications may make LIPP repair the procedure of choice for repair of ventral hernias.
Ventral hernia repairs are among the most frequently performed surgical procedures. The variations of repair techniques are multiple and outcome has been unacceptable. Despite the high volume, it has been difficult to obtain sufficient data to provide evidence for best practice. In order to monitor national surgical quality and provide the warranted high volume data, the first national ventral hernia register (The Danish Ventral Hernia Database) was established in 2007 in Denmark. The present study series show that data from a well-established database supported by clinical examinations, patient files, questionnaires, and administrative data makes it possible to obtain nationwide high volume data and to achieve evidence for better outcome in a complex surgical condition as ventral hernia. Due to the high volume and included variables on surgical technique, it is now possible to make analyses adjusting for a variety of surgical techniques and different hernia specifications. We documented high 30-day complications and recurrence rates for both primary and secondary ventral hernias in a nationwide cohort. Furthermore, recurrence found by clinical examination was shown to exceed the number of patients undergoing reoperation for recurrence by a factor 4-5. The nationwide adjusted analyses proved that open mesh and laparoscopic repair for umbilical and epigastric hernias does not differ in 30-day outcome or in risk of recurrence. There is a minor risk reduction in early complications after open sutured repairs. However, the risk for a later recurrence repair is significantly higher after sutured repairs compared with mesh repairs. The study series showed that large hernia defects and open re-pairs were independent predictors for 30-day complications after an incisional hernia repair. Open procedures and large hernia defects were independent risk factors for a later recurrence re-pair. However, patients with large defects (> 15 cm) seemed to benefit from an open mesh

Guidelines are increasingly determining the decision process in day-to-day clinical work. Guidelines describe the current best possible standard in diagnostics and therapy. They should be developed by an international panel of experts, whereby alongside individual experience, above all, the results of comparative studies are decisive. According to the results of high-ranking scientific studies published in peer-reviewed journals, statements and recommendations are formulated, and these are graded strictly according to the criteria of evidence-based medicine. Guidelines can therefore be valuable in helping particularly the young surgeon in his or her day-to-day work to find the best decision for the patient when confronted with a wide and confusing range of options. However, even experienced surgeons benefit because by virtue of a heavy workload and commitment, they often find it difficult to keep up with the ever-increasing published literature. All guidelines require regular updating, usually every 3 years, in line with progress in the field. The current Guidelines focus on technique and perioperative management of laparoscopic ventral hernia repair and constitute the first comprehensive guidelines on this topic. In this issue of Surgical Endoscopy, the first part of the Guidelines is published including sections on basics, indication for surgery, perioperative management, and key points of technique. The next part (Part 2) of the Guidelines will address complications and comparisons between open and laparoscopic techniques. Part 3 will cover mesh technology, hernia prophylaxis, technique-related issues, new technologic developments, lumbar and other unusual hernias, and training/education.

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.

Seroma after laparoscopic ventral hernia repair (LVHR) has been related to certain complications of the technique, such as recurrences and postoperative pain. The aim of this study was to assess whether percutaneous application of fibrin sealant in the hernia sac after LVHR reduces the incidence and volume of the postoperative seroma, and to analyze whether the percentage of patients achieving complete normalization of the abdominal wall increases. Prospective and comparative study. Patients were distributed into 2 control-case groups. Group 1 comprised patients submitted to LVHR using the double crown technique and a compressing bandage as the only method for prevent seroma. Group 2 comprised patients admitted to LVHR using the same technique together with percutaneous injection of fibrin sealant in the sac, and later applying the same bandage. Patients were examined clinically and radiologically at 7 days, 1 month, and 3 months after surgery. Twenty-five patients were included in each group. There were significant differences in the incidence of seroma by the day 7 after surgery (92% in group 1 vs. 64 % in group 2, p = 0.017) and by 1 month (72% in group 1 vs. 28% in group 2, p = 0.002). The difference was also significant regarding the achievement of normalization of the abdominal wall by day 7 (24% in group 1 vs. 52% in group 2, p = 0.041) and by month 1 (64% in group 1 vs. 88% in group 2, p = 0.047) after operation. Volume of seroma was larger among patients of group 1 after the week (p = 0.002) and 1 month after operation (p = 0.001). Fibrin sealant application after LVHR reduces the incidence and volume of the seroma 7 days and 1 month after surgery. The treated patients obtain a larger normalization of the abdominal wall 1 week and 1 month after the operation.
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

Intraabdominal pressure often is blamed as the cause of mesh-fascia junction failure after laparoscopic ventral hernia repair. Stretching of the mesh during a cough or defecation may lead to recurrence. Little is known about the movements of mesh in the abdominal cavity after this operation. This study investigated the front abdominal wall to describe its elasticity in vivo and searched for elongations that possibly stretched an implanted mesh, thereby causing fixation failure and subsequent recurrence. To measure front abdominal wall elongations, a model of fascia movements was created. Eight healthy volunteers were measured during exercise to determine the extent of elongations in their front abdominal wall. Videos were analyzed in three positions to create a mathematical shell structure. A computerized model based on the net movement of nodes was calculated to determine the axes and values for maximum elongations. The largest average elongations were measured for the upper midline (32.08%) and the transverse line in the low lateral area (34.06%). The maximum values for these lines were larger than 100% for the middle line (133.78%) and exceeded 50% for the entire middle line. The values for the horizontal lines did not reach 10% at any level. According to these data, areas of both high and low elasticity were defined. The presented experiment adds new parameters to the understanding of in vivo mesh behavior. Elongation of the front abdominal wall may stretch implanted mesh and could be a cause of recurrence in cases of insufficient fixation.

During the period October 1993 to December 1996, 31 patients were operated on by the author for primary or recurrent ventral incisional hernia (VIH). Three patients were excluded from analysis because their records were unavailable for review. The median age of the 28 remaining patients at their initial procedure was 57.5 years (range, 37-78 years). The repair was performed with interrupted O-Ethibond sutures in all but 3 cases where Prolene suture was used secondary to noniatrogenic contamination or recurrent hernia. There were no unplanned enterotomies in the entire series and prophylactic intravenous antibiotics were used in all cases. The only significant complications were skin hyperemia after five repairs in 3 patients who were treated empirically with intravenous antibiotics, and 1 patient who had an antibiotic-associated rash. There were no 30-day mortalities. Prolene mesh was used exclusively in all repairs performed with mesh. Seven of these repairs (25%) were for recurrent VIH. Three of these seven patients had previous mesh repairs. Six of these seven patients who presented with recurrent VIH had a mesh repair and four developed a recurrence. Five of seven were active smokers, with one having severe obstructive lung disease. Four of seven related significant occupational lifting. Of the 21 patients having initial repair of VIH, mesh was used in 8 (38%). After a median follow-up of 13 months, there were 2 recurrent hernias (25%). The remaining 13 patients had primary closure of their hernias. After median follow-up of 25 months, there were 5 recurrences (38%). A total of 34 VIH repairs were performed on these 28 patients, of which 13 were for recurrent hernias. Five of thirteen (38%) of the mesh repairs for recurrent VIH failed. The median body mass index (BMI) for the 13 patients having primary repair was 26.4, and that for all 21 cases having mesh repair was 28.8. Patients with recurrent VIH frequently recur despite use of mesh, avoidance of

A systemically altered connective tissue metabolism has been demonstrated in patients with abdominal wall hernias. The most pronounced connective tissue changes are found in patients with direct or recurrent inguinal hernias as opposed to patients with indirect inguinal hernias. The aim of the present study was to assess whether direct or recurrent inguinal hernias are associated with an elevated rate of ventral hernia surgery. In the nationwide Danish Hernia Database, a cohort of 92,457 patients operated on for inguinal hernias was recorded from January 1998 until June 2010. Eight-hundred forty-three (0.91 %) of these patients underwent a ventral hernia operation between January 2007 and June 2010. A multivariate logistic regression analysis was applied to assess an association between inguinal and ventral hernia repair. Direct (Odds Ratio [OR] = 1.28 [95 % CI, 1.08-1.51]) and recurrent (OR = 1.76, [95 % CI, 1.39-2.23]) inguinal hernias were significantly associated with ventral hernia repair after adjustment for age, gender, and surgical approach (open or laparoscopic). Patients with direct and recurrent inguinal herniation are more prone to ventral hernia repair than patients with indirect inguinal herniation. This is the first study to show that herniogenesis is associated with type of inguinal hernia.

Ventral hernia is a common medical problem. Statistically there are around 10% recurrences of the sickness. The authors' former investigation proved edges of the hernia orifice displacements to be one of the factors causing recurrence. Thus, experimental investigation of the abdomen surface deformation due to some normal activities of people is studied. Eight slim, healthy people were asked to extremely stretch their abdomens. Bending, stretching and expiration were considered. The deformations registration was made by two cameras located in front of the patient on both sides. Special calculation procedure was used in order to transform characteristic point displacements to strains of abdomen in different directions. The extreme strains, their localization and directions are identified. The study proves that the highest strains, bigger than 25% on average, appear in the upper part of the central vertical line of the abdomen and in lower sides in semi-vertical direction. The lowest strains, smaller than 7%, occur in a horizontal line situated low in the abdomen. For each patient similar zones of smaller or bigger strains are identified, however a wide discrepancy of the strain values obtained for different patients is stated. For example the strains in lower part in semi-vertical direction for one patient equals 9% and for another 134%! The acquired conclusions may be useful for surgeons in finding practical solutions to dilemmas concerning the choice of an implant (elastic or stiff) for a specific ventral hernia, its proper connection with fascia and orientation in the abdomen.

To review mesh products currently available for ventral hernia repair and to evaluate their efficacy in complex repair, including contaminated and reoperative fields. Although commonly referenced, the concept of the ideal prosthetic has never been fully realized. With the development of newer prosthetics and approaches to the ventral hernia repair, many surgeons do not fully understand the properties of the available prosthetics or the circumstances that warrant the use of a specific mesh. A systematic review of published literature from 1951 to June of 2009 was conducted to identify articles relating to ventral hernia repairs and the use of prosthetics in herniorrhaphy. Important differences exist between the synthetics, composites, and biologic prosthetics used for ventral hernia repair in terms of mechanics, cost, and the ideal situation in which each should be used. The use of synthetic mesh remains an appropriate solution for most ventral hernia repairs. Laparoscopic ventral hernia repair has created a niche for both expanded polytetrafluoroethylene and composite mesh, as they are suited to intraperitoneal placement. Preliminary studies have demonstrated that the newer biologic prosthetics are reasonable options for hernia repair in contaminated fields and for large abdominal wall defects; however, more studies need to be done before advocating the use of these biologics in other settings.

Large ventral hernias are known to induce atrophic changes to the anterior abdominal wall musculature. We have shown that anterior component separation with external oblique (EO) release, with resultant reconstruction of the midline, results in hypertrophy of the rectus muscle (RM), internal oblique (IO), and transversus abdominis (TA). We aimed to compare and contrast the impact of posterior component separation with transversus abdominis release (TAR) and bridging laparoscopic ventral hernia repair (LVHR) on the muscles of the abdominal wall. Preoperative and at least 6-month postoperative CT scans were analyzed for patients undergoing TAR with midline reconstruction and LVHR without midline reconstruction. A change in the measured area of each abdominal wall muscle was used as the determinant of hypertrophy or atrophy. The areas of the RM, EO, IO, and TA were measured at the L3 to L4 level through the axial plane. Twenty-five consecutive patients with pre- and postoperative images were analyzed in each group. In the TAR group, the RA, EO, and IO demonstrated significant increases in area. In the LVHR group, no muscles demonstrated any significant changes. Similar to anterior component separation, hernia repair with TAR results in hypertrophy of the rectus abdominis muscle. In addition, we found that TAR was associated with hypertrophy of both external and internal oblique muscles. Bridging repair during LVHR, on the other hand, did not result in any significant changes in any of the abdominal muscles. Our findings provide clear radiologic evidence that re-creation of the midline by means of the TAR leads to improved anatomy of the abdominal wall, in addition to positive compensatory changes of the lateral abdominal wall musculature.

INTRODUCTION The Ethicon™ laparoscopic inguinal groin hernia training (LIGHT) course is an educational course based on three days of teaching on laparoscopic hernia surgery. The first day involves didactic lectures with tutorials. The second day involves practical cadaveric procedures in laparoscopic hernia surgery. The third day involves direct supervision by a consultant surgeon during laparoscopic hernia surgery on a real patient. We reviewed our outcomes for procedures performed on real patients on the final day of the course for early complications and outcomes. METHODS A retrospective study was undertaken of patients who had laparoscopic hernia surgery as part of the LIGHT course from 2013 to 2015. A matched control cohort of patients who had elective laparoscopic hernia surgery over the study period was identified. These patients had their surgery performed by the same consultant general surgeons involved in delivering the course. All patients were followed up at 6 weeks postoperatively. RESULTS A total of 60 patients had a laparoscopic inguinal hernia repair and 23 patients had a laparoscopic ventral hernia repair during the course. The mean operative time for laparoscopic inguinal hernia repair was 48 minutes for trainees (range 22-90 minutes) and 35 minutes for consultant surgeons (range 18-80 minutes). There were no intraoperative injuries or returns to theatre in either group. All the patients operated on during the course were successfully performed as daycase procedures. The mean operative time for laparoscopic ventral hernia repair was 64 minutes for trainees (range 40-120 minutes) and 51 minutes for consultant surgeons (range 30-130 minutes). CONCLUSIONS The outcomes of patients operated on during the LIGHT course are comparable to procedures performed by a consultant. Supervised operating by trainees is a safe and effective educational model in hernia surgery.

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.

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.

Two-criteria optimisation problem related to laparoscopic ventral hernia repair is formulated in this paper. An optimal implant from a given set and its orientation is sought. The implant is subjected to kinematic extortions due to a patient's body movement and intra-abdominal pressure. The first criterion of the optimisation problem deals with the reaction force in the implant fastener, while the deflection of the implant constitutes the second criterion. A two-stage optimization procedure is proposed and the optimal solution is determined with the aid of minimization of an additional objective function. Numerical examples for typical locations of hernia are provided.

Over 300,000 ventral hernia repairs (VHRs) are performed each year in the US. We sought to assess the economic burden related to ventral hernia recurrences with a focused comparison of those with the initial open versus laparoscopic surgery. The Premier Alliance database from 2009 to 2014 was utilized to obtain patient demographics and comorbid indices, including the Charlson comorbidity index (CCI). Total hospital cost and resource expenses during index laparoscopic and open VHRs and subsequent recurrent repairs were also obtained. The sample was separated into laparoscopic and open repair groups from the initial operation. Adjusted and propensity score matched cost outcome data were then compared amongst groups. One thousand and seventy-seven patients were used for the analysis with a recurrence rate of 3.78 %. For the combined sample, costs were significantly higher during recurrent hernia repair hospitalization ($21,726 versus $19,484, p < 0.0001). However, for index laparoscopic repairs, both the adjusted total hospital cost and department level costs were similar during the index and the recurrent visit. The costs and resource utilization did not go up due to recurrence, even though these patients had greater severity during the recurrent visit (CCI score 0.92 versus 1.06; p = 0.0092). Using a matched sample, the total hospital recurrence cost was higher for the initial open group compared to laparoscopic group ($14,520 versus $12,649; p = 0.0454). Based on our analysis, need for recurrent VHR adds substantially to total hospital costs and resource utilization. Following initial laparoscopic repair, however, the total cost of recurrent repair is not significantly increased, as it is following initial open repair. When comparing the initial laparoscopic repair versus open, the cost of recurrence was higher for the prior open repair group.

This retrospective chart analysis reports and assesses the long-term (beyond 10 years) safety and efficiency of a single institution's experience in 1326 laparoscopic incisional and ventral hernia repairs (LIVHR), defending the principle of the suturing defect (augmentation repair concept) prior to laparoscopic reinforcement with a composite mesh (IPOM Plus). This study aims to prove the feasibility and validity of IPOM Plus repair, among other concepts, as a well-justified treatment of incisional or ventral hernias, rendering a good long-term outcome result. A single institution's systematic retrospective review of 1326 LIVHR was conducted between the years 2000 and 2014. A standardized technique of routine closure of the defect prior to the intraperitoneal onlay mesh (IPOM) reinforcement was performed in all patients. The standardized technique of "defect closure" by laparoscopy approximating the linea alba under physiological tension was assigned by either the transparietal U reverse interrupted stitches or the extracorporeal closure in larger defects. All patients benefited from the implant Parietex composite mesh through an Intraperitoneal Onlay Mesh placement with transfacial suturing. LIVHR was performed on 1326 patients, 52.57% female and 47.43% male. The majority of our patients were young (mean age 52.19 years) and obese (average BMI 32.57 kg/m2). The mean operating time was 70 min and hospital stay 2 days, with a mean follow-up of 78 months. On the overall early complications of 5.78%, we achieved over time the elimination of the dead space by routine closure of the defect, thus reducing seroma formation to 2.56%, with a low risk of infection <1%. Post-op sepsis occurred in only nine cases. Three secondary serosal breakdowns and two late perforations were re-operated, and three diabetic patients had infected hematomas, necessitating mesh removal. Through technical improvement in the suturing concept and our growing experience, we managed to reduce the

The absence of a standardized classification scheme for ventral hernias hinders comparisons within the literature, indirectly delaying meaningful discussions regarding technique. We aimed to generate a comprehensive staging system that stratifies patients by risk of developing wound morbidity and hernia recurrence. Our prospective database of all ventral hernia repairs (2006-2013) was reviewed with no exclusion based on technique or prosthetic. The presence of patient comorbidities, contamination and hernia dimensions-width/location on computed topography-was evaluated to identify variables most closely associated with surgical site occurrence (SSO) and recurrence. Predicted odds ratios and relative hazards, for SSO and recurrence, respectively, were used to partition patients into stages corresponding with increasing levels of risk. Hernia width (OR 2.24, HR 1.73) and the presence of contamination (OR 1.81, HR 2.04) were most significantly associated with increased risk of SSO and recurrence, while hernia location and the presence of comorbidities were not. Stage I hernias are <10 cm/clean and associated with low SSO and recurrence risk. Stage II hernias are 10-20 cm/clean or <10 cm contaminated and carry an intermediate risk of SSO and recurrence. Stage III hernias are either ≥10/contaminated or any hernia ≥20 cm, and these are associated with high SSO and recurrence risk. Stages I-III carry a concordance index of 0.67 for SSO and 0.61 for recurrence. Hernia width and wound class can be used to stratify patients into stages (I-III) with increasing risk of wound morbidity and recurrence. This can be the foundation for future inclusion and exclusion criteria.

Spigelian hernia (SH) is a rare ventral hernia occurring near the lateral border of the rectus muscle. The treatment remains controversial and depends on institutional expertise. Although laparoscopic surgery is a good adaptation for the repair of ventral hernias, only a few cases have been reported in the literature. Here, we report a case of totally extra-peritoneal (TEP) repair for bilateral SHs. A 74-year-old Japanese man presented with asymptomatic bulges in the right lower abdominal quadrant. On physical examination, the bulges were located to the right of the lateral border of the abdominal rectus muscle and the right inguinal region in an upright position. We diagnosed right SH and coincident homonymous ipsilateral inguinal hernia (IH) by abdominal computed tomography and planned a curative operation by laparoscopy. By first laparoscopic exploration, we found an asymptomatic SH to the left of the lateral border of the abdominal rectus muscle and performed TEP repair for all hernias. The second laparoscopic exploration after fixing the mesh in place revealed that the orifice of the right SH was scarred and stiffened by repeated prolapse. We finally eliminated the sac by ligation because of a fear causing of reduction en masse of the SH. The use of laparoscopy simplified the diagnosis and facilitates the subsequent repair of the hernia. TEP approach is the ideal treatment for the simultaneous laparoscopic repair of SH and IH.

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.

Repair of ventral hernias constitutes one of the most common surgical procedures. Although an abundance of data exists on objective outcome measures, very little information exists on subjective measures of surgeon preference and patient satisfaction in surgical management of ventral hernias. Moreover, there are minimal data on indications for elective repair of ventral hernias. Two questionnaires were sent to a population of general and plastic surgeons active in hernia surgery. The first of these aimed at gathering information from surgeons about their indications and contraindications for repair of ventral hernias. The second survey was aimed at determining surgeons' perception of patient satisfaction with repair of large ventral hernias (greater than 15 cm width). Five hundred sixty-eight surgeons responded to the first survey and 336 responded to the second survey. The most common indications for elective repair of abdominal wall hernias were generalized pain (68.7%) and cosmesis (54.6%), whereas the most common contraindications were morbid obesity (43.3%), American Society of Anesthesiologists Class III or IV (35.4%), and enterocutaneous fistula (33.1%). The majority of surgeons do not routinely repair large abdominal wall hernias in asymptomatic patients, but 31.6 per cent do repair asymptomatic large hernias. Most surgeons reported that the majority of patients had resolution of pain and subjective impression of improved cosmesis after surgery. This study demonstrates uniform indications and contraindications for surgical repair of ventral hernias among surgeons as well as surgeons' perception of improvements in satisfaction of most patients after surgery. Future studies will focus on comparing surgeon and patient satisfaction.

Laparoscopic inguinal hernia repair is performed more and more nowadays. The anatomy of these procedures is totally different from traditional open procedures because they are performed from different direction and in different space. The important anatomy essentials for laparoscopic inguinal hernia repair will be discussed in this article.

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

Bochdalek's hernia is a type of congenital diaphragmatic hernia occurring in approximately 1 in 2200–12 500 live births. It is considered to be extremely rare in adults and poses a diagnostic challenge. We present a case of a young man who was diagnosed as a case of congenital Bochdalek's hernia and underwent laparoscopic mesh repair. PMID:23761496
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

Obesity may be the most predominant risk factor for recurrence following ventral hernia repair. This is secondary to significantly increased intra-abdominal pressures, higher rates of wound complications, and the technical difficulties encountered due to obesity. Medically managed weight loss prior to surgery is difficult. One potential strategy is to provide a surgical means to correct patient weight prior to hernia repair. After institutional review board approval, we reviewed the medical records of all patients who underwent gastric bypass surgery prior to the definitive repair of a complex ventral hernia at our medical center. Twenty-seven morbidly obese patients with an average of 3.7 (range 1-10) failed ventral hernia repairs underwent gastric bypass prior to definitive ventral hernia repair. Twenty-two of the gastric bypasses were open operations and five were laparoscopic. The patients' average pre-bypass body mass index (BMI) was 51 kg/m2 (range 39-69 kg/m2), which decreased to an average of 33 kg/m2 (range 25-37 kg/m2) at the time of hernia repair at a mean of 1.3 years (range 0.9-3.1 years) after gastric bypass. Seven patients had hernia repair at the same time as their gastric bypass (four sutured, three biologic mesh), all of which recurred. Of the 27 patients, 19 had an open hernia repair and eight had a laparoscopic repair. Panniculectomy was performed concurrently in 15 patients who had an open repair. Prior to formal hernia repair, one patient required an urgent operation to repair a hernia incarceration and a small-bowel obstruction 11 months after gastric bypass. The average hernia and mesh size was 203 cm2 (range 24-1,350 cm2) and 1,040 cm2 (range 400-2,700 cm2), respectively. There have been no recurrences at an average follow-up of 20 months (range 2 months-5 years). Gastric bypass prior to staged ventral hernia repair in morbidly obese patients with complex ventral hernias is a safe and definitive method to effect weight loss and facilitate a
Complex hernias continue to present a challenge. Surgical techniques for repair are carefully considered to reduce risk for complications. Laparoscopic repairs improve postoperative infection rates, and placement of biologic mesh decreases mesh infection rates. However, laparoscopic repairs using biologic mesh is generally challenging due to difficulty with maneuverability. We present a case of a complex ventral hernia that was laparoscopically repaired using a new FDA cleared laparoscopic biologic graft. The patient had multiple comorbidities, including obesity, hepatitis C, endocarditis secondary to IV drug use, tobacco smoking, bilateral inguinal hernia, and recurrent umbilical hernia. The recurrent hernia was larger, irreducible, and discolored compared to original defect. The patient underwent laparoscopic repair with primary closure and reinforcement with Strattice™ Tissue Matrix Laparoscopic (LifeCell Corporation, Branchburg, NJ). At nine months postoperative, the patient had no evidence of recurrence, infection, or chronic pain, demonstrating early success from the surgical management. Presence of multiple comorbidities and incarcerated recurrent hernia increase risk for complications during and/or after hernia repair. Considering these factors, laparoscopic repair with Strattice Laparoscopic and defect closure was a reasonable technique for repair. Laparoscopic suture repair reinforced with biologic dermal tissue matrix was successfully performed during a complex hernia repair. Copyright © 2014 The Author. Published by Elsevier Ltd..

Spiegelian hernia is a rare type of ventral abdominal hernia. Surgical treatment is recommended due to the high risk of complications. Laparoscopic treatment is preferred to open repair, by means of intraperitoneal or extraperitoneal mesh placement, either by transperitoneal(TAPP) or by total extraperitoneal (TEP) approach. Total extraperitoneal approach is rarely reported in the literature. To evaluate the results of laparoscopic repair of Spiegelhernia by total extraperitoneal approach. We prospectively studied the patients operated on for Spiegel hernia between October 2009 and March 2013 by laparoscopic TEP approach at Ponderas Hospital. Data regarding symptoms, sex, preoperative work-up,surgical technique, hospital stay and outcome of the procedure were analysed. Follow-up of the patients was achieved at 1week, 1 month, 6 months and yearly postoperatively and patients were evaluated for recurrence, chronic pain, mesh infection, time to reinsertion to normal activities and overall patient satisfaction score. We have treated 4 patients with Spiegel hernia by laparoscopic TEP repair, with mean age 55.25 years (range 50-64), sex ratio 1 (2 2); all patients were symptomatic, all cases had left sided hernias, the surgical intervention was elective in all cases. Mean hospital stay was 1.5 days (range1- 2 days). There was only one postoperative complication ina patient with asymptomatic seroma, with remission in 1 month. There were no recurrences, no mesh infection, no chronic pain or other morbidity at a mean follow-up of 25 months (range 12-53 months). The overall satisfaction score was maximal (5) in all cases. Spiegelian hernias are rare but surgery is mandatory because of the risk of complications like incarceration and strangulation. In the presented experience, laparoscopic total extraperitoneal approach proved to be an efficient technique,reproducible, with excellent results for Spiegel hernia treated electively. Celsius.

Introduction: Composite mesh prostheses incorporate the properties of multiple materials for ventral hernia repair. This study evaluated a polypropylene/ePTFE composite mesh with a novel internal polydioxanone (PDO) absorbable ring. Methods: Composite mesh was placed intraperitoneally in 16 pigs through an open laparotomy and explanted at 2, 4, 8, and 12 weeks. Intraabdominal adhesions were measured laparoscopically. Host tissue in-growth was assessed histologically and tensiometrically. Degradation of the internal PDO ring component was also measured tensiometrically. Appropriate statistical tests were used, and P≤.05 indicated significance. Results: No adhesions were formed in 50% of the grafts explanted at 8 weeks and 25% of grafts explanted at 12 weeks. There were significantly more vascular structures at 8 weeks, 73.5±28, compared with 2 weeks, 6.75±2 (P≤.01). The T-peel force at the mesh-host tissue interface was not significantly different among time points. The absorbable PDO ring underwent complete degradation by 12 weeks. Conclusions: This composite mesh was associated with minimal intraabdominal adhesions, progressive in-growth of host tissues, and complete degradation of a novel internal PDO ring that aided mesh positioning. This composite hernia mesh showed a favorable performance in a porcine model of open ventral hernia repair. PMID:21985713

Incisional hernias and other ventral hernias are common surgical problems. It is estimated that incisional hernia complicates about 2 % to 10 % of laparotomies. Ventral and incisional hernia repairs are among the common surgeries done by a general surgeon. It is proven beyond any doubt that suture repair of these hernias should not be done as recurrence rates are unacceptably high, some series reporting as high as 54 % on long-term follow-up. A prosthetic mesh should always be used in ventral hernia repair (VHR). Now, the polypropylene mesh (PPM) has become the prosthetic mesh of choice in the repair of hernias, including inguinal hernia. However, with the advent of laparoscopic repair where the mesh is placed intraperitoneally, concerns regarding safety of PPM are raised. Newer meshes are introduced, claiming lesser complication rate. Many types of newer meshes are available now. Newer meshes are invariably costlier than PPM by 15-20 times. Is this extra cost worth? We looked in to available literature for an answer.

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.

Laparoscopic ventral hernia repair (LVHR) is a relatively common procedure that requires advanced minimally invasive surgical skills to perform. The role for simulation is increasingly supported as an effective way to teach surgical skills and accelerate the learning curve. This article describes The University of Maryland's Surgical Abdominal Wall, an inexpensive procedure-specific physical simulator for LVHR, and summarizes the authors' early experiences using this model in a curriculum for surgery residents.

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.

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.

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

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
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

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

It is an acceptable concept that the ventral hernia defect area will increase with a rise in intra-abdominal pressure (IAP). The literature lacks the evidence about how much this increase is in vivo. The aim of this study was to objectively measure the change in the ventral hernia defect area with increasing intra-abdominal pressure. In a prospective study of laparoscopic ventral hernia repair, the area of hernia defect was measured from inside the abdomen using a sterile paper ruler. The horizontal (width) and vertical (length) measurements of the defect were taken at two pressure points: (IAP = 8 mmHg) and (IAP = 15 mmHg). The hernia defect area was calculated as an oval shape using a standard formula. Eighteen consecutive patients with a ventral hernia were included in this study (8 males: 10 females). Median age was 60 years (30-81), body mass index (BMI) was 29.9 (22.6-37.6). Changing the IAP significantly, (P < 0.001) changed the values of horizontal and vertical measurements, and the calculated area of the ventral hernia defect. The median calculated defect area, as an oval shape, was 5.6 cm(2) (Q1-Q3 = 3.5-15.5) and 6.9 cm(2) (Q1-Q3 = 4.5-18.7) at 8 and 15 mmHg IAP, respectively. The calculated area of mesh required to cover the defect with a 5 cm overlap increased by a median of 5% (Q1-Q3 = 3-6%). The change in defect area did not differ significantly between obese and non-obese patients (P = 0.5). Dynamic, rather than static, measurements of ventral hernia area during laparoscopy provide a simple way of in vivo objective measurement that helps the surgeon choose the appropriate area of mesh. When choosing mesh area, we support the trend toward a larger overlap of at least 5 cm if less precise methods of measuring defect area are been used.

Hernias of the ventral abdominal wall can be treated with an intraperitoneal onlay mesh (IPOM). The aim of this cohort study was to analyze the complications and recurrence rates after laparoscopic ventral hernia repair focusing especially on incisional and recurrent hernias. The study population comprised 149 patients with a hernia of the abdominal wall, which was treated with an IPOM between January 2006 and January 2011. Fifty-one patients had a primary hernia (group I) and 98 patients had preceding abdominal surgery (group II). In group II 64 patients had an incisional hernia and 34 patients had a recurrent hernia. The median body mass index was 30.3 kg/m(2) (14.8-69.1) without any significance in sub-group comparison. The mean duration of surgery and the length of stay were significantly longer in group II (p < 0.05). The overall rate of minor complications was 18.1%. There were significantly more minor complications in group II (7.8% vs. 23.5%, p = 0.02). Notably, there were also significantly more major complications in group II (14.3% vs. 2.0%; p = 0.02). The recurrence rate was significantly higher in group II (group I: 3.9% vs. group II: 16.3%, p < 0.05). There were no early recurrences in group I, but 5 early recurrences in group II. Laparoscopic treatment of complex hernias as incisional hernias, recurrent hernias and hernias with interenteric and enteroperitoneal adhesions is associated with high rates of minor and major complications. A high level of expertise of the surgeon and the camera-guiding assistant is therefore needed. Copyright © 2015 IJS Publishing Group Limited. Published by Elsevier Ltd. All rights reserved.

Summary: Skin deficient complex ventral hernias are complicated surgical cases that have multimodal approaches. There is no current consensus on the management of those patients who also have concomitant stomas or enterocutaneous fistula. We present 2 cases in which the senior authors were able to apply tissue expanders above and between the abdominal wall in patients with an enterocutaneous fistula or stoma. After expansion and final closure, the patients did not experience recurrent hernias. PMID:26893988

Although composite surgical meshes are widely used in laparoscopic repair of ventral hernia, the risk of postoperative complications associated with these type of mesh is relatively high. In this report, we demonstrated the safety as well as the effectiveness of a new composite polypropylene mesh coated with poly Llactidecocaprolactone ε (EasyProsthesTM) for the repair of ventral hernia. This study was a randomized, controlled trial designed to compare EasyProsthes composite mesh (EPM) with ParietexTM Composite (PCO) in patients undergoing laparoscopic ventral hernia repair. Hernia recurrence, chronic pain, seroma formation, intestinal fistula or obstruction, wound or abdominal infection, and viscera adhesion were evaluated. 80 patients who needed repair surgery for primary or secondary ventral hernias were enrolled in this study. Patients were divided into two groups: the EPM group (n=40) and the PCO group (n=40). Patients completed 12 months of followup. Our results revealed that one patient in the EPM group (2.5%) and two patients in the PCO group (5%) developed mesh viscera adhesions after surgery (p=1.000). We had no case of intestinal fistulas or obstruction. Seventeen patients in EPM group (42.5%) and 21 in PCO group (52.2%) developed post surgical seromas in the surgery area (p=0.370). One patient from each group developed postoperative wound infection. There was no case of abdominal infection, chronic pain or hernia recurrence. The incidence of postoperative complications in the EPM group was similar to that observed in the PCO group. We concluded that EPM is a safe and effective method to be used in ventral hernia repair surgeries.

To compare the outcome after laparoscopic incisional and ventral herniorrhaphy (LIVH) for fascial defect larger or equal than 15 cm in width with the outcome after LIVH in patients with hernia defect smaller than 15 cm. From 2003 through 2010, 350 patients were submitted to LIVH. In 70 cases, hernia defect was ≥15 cm in width and in 280 was <15 cm. Incisional hernias were often recurrent, double or multiorificial. In the group of larger hernias, the rate of obesity, recurrent hernia and multiorificial hernia was 27.1, 24.2 and 12.8 %, respectively, and in the group of smaller hernias 27.3, 16.1 and 2.8 %, respectively. Patients were interviewed using McGill pain score test to measure postoperative quality of life (QoL) in the mid-term. LIVH for hernia ≥15 cm required longer surgical time (p = 0.034) and postoperative hospital stay (p = 0.0001). Besides, there were higher rate of postoperative prolonged ileus (p = 0.035) and polmonitis (p = 0.001). Overall recurrence rate was 2.6, 8.6 % for larger and 1.1 % for smaller incisional hernias, p = 0.045. Mc Gill pain test revealed no significant difference in the two groups of patients in postoperative QoL within 36 months. Laparoscopic approach seems safe and effective even to repair large incisional hernia, the rate of recurrence was higher, but acceptable, if compared to smaller hernias. To the best of our knowledge, this is the largest reported series of incisional hernias ≥15 cm managed by laparoscopy.

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

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).

One distinct advantage of laparoscopic inguinal hernia repair is the opportunity for clear visualization of the direct, indirect, femoral, obturator and other groin spaces. The aim of this study was to examine/assess the potential of the laparoscopic totally extraperitoneal (TEP) inguinal hernia repair method in detecting unexpected additional hernias. Patients who underwent an elective inguinal hernia repair, in the department of abdominal surgery at the institute of laparoscopic surgery (ILS, Bordeaux, France) between September 2003 and July 2005 were enrolled prospectively in the study. The patients' demographic data, operative, postoperative course and outpatient follow-up were studied. A total of 337 laparoscopic inguinal hernia repairs were performed in 263 patients. Of these, 189 patients had unilateral hernia (109 right and 80 left) and 74 patients had bilateral hernias. Indirect hernias were the most common, followed by direct and then femoral hernias. There were 218 male patients and 45 female patients with a mean age of 60 ± 15 years. There were 44 unexpected hernias: 6 spegilian hernias, 19 obturator hernias and another 19 femoral hernias. Two patients were converted to transabdominal preperitoneal (TAPP) due to surgical difficulties. There were no major intraoperative complications in all patients except for three cases of bleeding arising from the inferior epigastric artery. Only one patient had postoperative bleeding and was re-operated on several hours after the hernia repair. No recurrence occurred in the present series. The laparoscopic inguinal hernia repair approach allows viewing of the entire myopectineal orifice, facilitating repair of any unexpected hernias and thereby reducing the chance of recurrence.

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.

Spigelian hernias represent only 1% to 2% of all abdominal wall hernias. The treatment, however, remains controversial but depends on institutional expertise. This case series reports the first experience with single-incision laparoscopic totally extraperitoneal (SILTEP) repair of Spigelian hernias with telescopic extraperitoneal dissection in combination with inguinal hernia repair. From February 2013 to April 2014, all patients referred with inguinal or Spigelian hernias, without histories of extraperitoneal intervention, underwent SILTEP repair with telescopic extraperitoneal dissection. A single-port device, 5.5 mm/52 cm/30° angled laparoscope, and conventional straight dissecting instruments were used for all cases. Extraperitoneal dissection was performed under direct vision with preservation of preperitoneal fascia overlying retroperitoneal nerves. Inguinal herniorrhaphy was performed with lightweight mesh that covered low-lying Spigelian defects. High-lying Spigelian defects were repaired with additional mesh. There were 131 patients with 186 (92 direct) inguinal hernias and 7 patients with 8 Spigelian hernias (6 incidental, including 1 bilateral and 2 preoperatively diagnosed), with a mean age of 51.3 years and a mean body mass index of 25.1 kg/m(2). An additional piece of mesh was used for 3 hernias. All Spigelian hernias were associated with direct inguinal hernias, and 8 combined inguinal and Spigelian hernias were successfully repaired with SILTEP repair with telescopic extraperitoneal dissection as day cases. There were no clinical recurrences during a mean follow-up period of 6 months (range, 1-15 months). Combined Spigelian and inguinal hernias can be successfully treated with SILTEP herniorrhaphy with telescopic extraperitoneal dissection. The high incidence of Spigelian hernias associated with direct inguinal hernias suggests a high index of suspicion for Spigelian hernias during laparoscopic inguinal herniorrhaphy.

The absence of recurrence and pain are important for good quality of life (QoL) after ventral hernia mesh repair. We wanted to study long-term outcome after laparoscopic (LVHR) and open ventral hernia mesh repair (OVHR) using validated scales to measure QoL and functional outcome. We conducted a single-center follow-up study of 194 consecutive patients after LVHR and OVHR between March 2000 and June 2010. Of these, 27 patients (13.9 %) died and 14 (7.2 %) failed to attend their follow-up appointment. Of 153 (78.9 %) patients who attended, 81 (52.9 %) patients had LVHR and 72 (47.1 %) patients had OVHR, including 11 conversions (surgery group). One hundred and twelve patients with non-recurrent ventral hernia were also enrolled consecutively as controls (non-surgery group). Quality of life was measured by the SF-36 short form questionnaire and functional outcome by the Activities Assessment Scale (AAS) with the revised Life Orientation Test to measure the influence of dispositional optimism on pain and functionality. Assessment of pain was done using a 100-mm visual analogue scale ruler anchored by word descriptors. Median time from hernia mesh repair to follow-up was 48 and 52 months after LVHR and OVHR, respectively. There were no long-term differences between LVHR and OVHR measured by SF-36 and AAS. Physical dimensions in SF-36: physical function, restrictions in physical function and bodily pain, were significantly better in the surgery group compared to the non-surgery group, but only for incisional hernia. Recurrence was associated with a significant reduction in QoL in all dimensions of SF-36 in both hernia repair cohorts. Chronic pain and impairment were closely related. Optimistic patients had less impairment than pessimistic patients. LVHR and OVHR reduce chronic pain and physical impairment and improve long-term QoL. Hernia recurrence and persistent pain reduce the beneficial effect of hernia surgery. Dispositional optimism can modulate Qo

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.

Laparoscopic herniotomy is the preferred technique for some ventral hernias. Several factors may influence the surgical conditions, one being the depth of neuromuscular blockade (NMB) applied. We hypothesised that deep neuromuscular blockade defined as a post-tetanic count below eight would provide a better surgical workspace. This was an investigator-initiated, assessor- and patient-blinded randomised cross-over study. A total of 34 patients with planned laparoscopic umbilical, incisional and linea alba herniotomy were studied. Patients would be randomised to receive deep NMB followed by no NMB, or no NMB followed by deep NMB. Our primary outcome was improvement of the surgical workspace (rated on a five-point scale) estimated as the difference between the workspace during deep NMB and the workspace without NMB. Secondary outcomes included, among others, surgeon's rating of surgical conditions during suturing, duration of surgery and duration of the suturing of the hernia. This randomised cross-over study investigated a potential effect on the surgical workspace in laparoscopic ventral herniotomy using deep NMB compared with no NMB. The study may provide knowledge relevant to other laparoscopic techniques. The study is funded by a research grant from the Investigator Initiated Studies Program of Merck Sharp & Dohme Corp. NCT02247466.

The results of surgical treatment of of 392 patients with postoperative ventral hernia are discussed. The algorithm of treatment of patients with large hernias was developed. Special preoperative management by dosed pneumocompression in an antioverload costume makes it possible to avoid menacing complications after the operation, which are caused by increased intraabdominal pressure. Test for tolerance to increase of intraabodominal pressure allowed prognostication of the character of the operative intervention: with or without decrease of the volume of the abdominal cavity (autoplasty or alloplasty, respectively). Prevention of wound complications consisted in control of infection, improvement of operative techniques, and use of modern surgical instruments. The prevention of recurrent hernias should be directed at correct choice of the method of plastics and removal of wound complications.

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

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

Laparoscopic repair of scrotal hernias is often a difficult endeavor to successfully complete. The longstanding nature of these hernias often results in significant adhesions and anatomic distortion of the inguinal floor. These two issues make reduction of the hernia arduous and subsequent reinforcement of the parietal sac difficult. We have previously described techniques to increase the chances of success when attempting laparoscopic repair of scrotal hernias. Here, we describe some of those techniques as well as a combined laparoscopic and open approach to achieve a robust preperitoneal repair of incarcerated scrotal hernias when the usual totally extraperitoneal approach does not work. We performed a retrospective review of 1890 TEP hernia repairs we performed from 1990 to 2010. Rate of conversion to an open approach or a combined laparoscopic and open approach was examined. Incidence of complications or recurrences was assessed over a 12-month follow-up period. Among the 1890 TEP repairs, 94 large scrotal hernias were identified. Of these, nine cases (9.5 %) required conversion to an open procedure due to an incarcerated and indurated omentum. Three were completed with a conventional open preperitoneal whereas six patients (6.4 %) underwent repair with the combined approach. In this group, no recurrences or complications were found over a 12-month period. In cases where a large scrotal hernia may be difficult or dangerous to reduce laparoscopically, immediate conversion to an open repair may not be necessary. A combined laparoscopic and open approach can greatly assist in the visualization and dissection of the preperitoneal space, thereby facilitating reduction of the hernia and placement of the mesh.

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.

Giant ventral hernias represent a real handicap for patients and constitute a challenge for surgeons. European Hernia Society classification defines all ventral hernia over 10 cm in the same group. However, this group represents different clinical entities with numerous therapeutic possibilities, and no standardized recommendation has been made. The objective of our work was to define consensual criteria that define giant ventral hernias requiring specific management and determine management modalities. A national survey consisting of 21 questions was proposed through a secure, anonymous internet interface and on a voluntary basis to all surgeons practising in France involved in care of patients affected by giant ventral hernias. For more than 68% of respondents, loss of domain and a hernia volume greater than 30% of abdominal volume were mandatory to define giant ventral hernias. Pre-operative screening should include abdominal CT scan, functional respiratory exploration, and a cardiology consultation for 98%, 71% and 50% of the respondents respectively. Respiratory and cutaneous preparations were systematically proposed before surgery by 91% and 56% of respondents. Regarding surgical techniques, none has gained the support of the majority of respondents. However, 71% of respondents use a non-resorbable mesh in retro muscular position for more than 70% of their patients treated for giant ventral hernias. Giant ventral hernias could be defined as ventral hernia larger than 10 cm with loss of domain. A specific management is advocated. Copyright © 2016 IJS Publishing Group Limited.

This retrospective study aims at analyzing the functional results obtained in patients operated by laparoscopy for a para-esophageal hernia. From 1994 to 2004, 38 patients underwent a laparoscopic procedure for a symptomatic para-esophageal hiatal hernia of at least 3/4 of the proximal stomach: 27 females and 11 males, mean age 65 years (extreme: 22-84). There was no case on emergency, 4 patients had have at least one episode of intrathoracic volvulus. The operation consisted in gastric reduction into the abdominal cavity, excision of the sac, suture of the crura reinforced with a mesh in 6 patients and the construction of a gastric wrap. A postoperative barium swallow was performed on POD 3 in order to confirm the anatomical result. Mean operating time was 157 minutes (75-480), no case was converted into laparotomy. Four postoperative complications were observed (morbidity 10.8%): one gastric perforation diagnosed on POD 1, 2 severe dysphagias linked to the wrap, and one atelectasia. There was no death in this series. Functional results were evaluated by the mean of a questionnaire in 33 patients who had a follow up more than 6 months. Thirty-three questionnaires have been sent, 3 patients were lost and one was dead. Among the 29 patients analyzed, 14 were very satisfied, 11 were satisfied and 3 were deceived by the operation. Best results are obtained in patients with GERD, dysphagia or postprandial cardiothoracic symptoms. These results compared to the published data allow us to discuss about indications of surgery, the necessity to removal the hernia sac, and the advantages to reinforce the crura by the mean of a non absorbable mesh.

Mesh options for reinforcement of ventral/incisional hernia (VIH) repair include synthetic or biologic materials. While each material has known advantages and disadvantages, little is understood about outcomes when these materials are used in combination. This multicenter study reports on the first human use of a novel synthetic/biologic hybrid mesh (Zenapro(®) Hybrid Hernia Repair Device) for VIH repair. This prospective, multicenter post-market clinical trial enrolled consecutive adults who underwent elective VIH repair with hybrid mesh placed in the intraperitoneal or retromuscular/preperitoneal position. Patients were classified as Ventral Hernia Working Group (VHWG) grades 1-3 and had clean or clean-contaminated wounds. Outcomes of ventral and incisional hernia were compared using appropriate parametric tests. In all, 63 patients underwent VIH repair with hybrid mesh. Most were females (54.0%), had a mean age of 54.8 ± 10.9 years and mean body mass index of 34.5 ± 7.8 kg/m(2), and classified as VHWG grade 2 (87.3%). Most defects were midline (92.1%) with a mean area of 106 ± 155 cm(2). Cases were commonly classified as clean (92.1%) and were performed laparoscopically (60.3%). Primary fascial closure was achieved in 82.5% with 28.2% requiring component separation. Mesh location was frequently intraperitoneal (69.8%). Overall, 39% of patients available for follow-up at 12 months suffered surgical site events, which were generally more frequent after incisional hernia repair. Of these, seroma (23.7%) was most common, but few (8.5%) required procedural intervention. Other surgical site events that required procedural intervention included hematoma (1.7%), wound dehiscence (1.7%), and surgical site infection (3.4%). Recurrence rate was 6.8% (95% CI 2.2-16.6%) at 12-months postoperatively. Zenapro(®) Hybrid Hernia Repair Device is safe and effective in VHWG grade 1-2 patients with clean wounds out to 12 months. Short-term outcomes and recurrence

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.

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

Introduction Esophageal hiatal hernias are the most frequent types of internal hernias. This condition involves disturbance of normal functioning of the stomach cardiac mechanism and reflux of the gastric contents to the esophagus. Aim: To evaluate postoperative results in our Clinic and the comparison of these results to data from the literature. Material and methods One hundred and seventy-eight patients underwent surgery due to esophageal hiatal hernia at the Clinic of General, Gastroenterological and Oncological Surgery, Collegium Medicum, Bydgoszcz, Nicolaus Copernicus University, Torun, Poland, from 2006 to 2011. All operations were performed using laparoscopy. Fundoplication by means of the Nissen-Rossetti method was carried out in 172 patients while Toupet's and Dor's methods were applied in 4 and 2 patients, respectively. Results Average time of the surgery was 82 min (55–140 min). Conversion was performed in 4 cases. No serious intraoperative complications were noted. In the postoperative period, dysphagia was reported in 20 patients (11.2%). Postoperative wound infection was observed in 1 patient (0.56%). Hernias in the trocar insertion area were reported in 3 patients (1.68%). Ailments recurred in 6 patients. The recurrence of esophageal hiatal hernia was confirmed in 2 patients. Patients with recurrent hernia were re-operated using a laparoscopic approach. Conclusions Laparoscopic surgery is a simple and effective approach for patients with gastroesophageal reflux symptoms due to diaphragmatic esophageal hiatus hernia. The number of complications is lower after laparoscopic procedures than after “open” operations. PMID:24729804

Laparoscopic inguinal hernia repair in children is in evolution. Multiple methods of passing the suture around the peritoneum at the level of the internal inguinal ring exist. Cauterization of the peritoneum at the internal ring is thought to increase scarring and decrease recurrence. We have employed a sutureless, cautery only, laparoscopic single port repair of inguinal hernias and patent processus vaginalis (PPV) in girls. After institutional ethical review was obtained, a retrospective review of sutureless laparoscopic inguinal hernia repairs in girls by 4 surgeons at separate institutions was performed. Patient demographics, intraoperative findings, and postoperative outcomes were recorded and analyzed. The technique involves an umbilical 30° camera and either a separate 3 mm stab incision in the midclavicular line or a 3 mm Maryland grasper placed next to the camera, and the distal most portion of the hernia sac is grasped and pulled into the abdomen and cauterized obliterating the sac. Eighty inguinal hernias were repaired using this technique in 67 girls between July 2009 and September 2015. The ages and weights ranged from 1 month to 16 years and from 2 to 69 kg, respectively. There was one conversion to open approach because an incarcerated ovary was too close to the ring. A single umbilical incision was utilized in 85%. Fifty-seven percent patients had hernias on the right whereas 42% had hernias on the left. Of the patients with presumed unilateral hernias, 22 patients were found to have PPV and were treated through the same incisions, 17/22 were found during a contralateral hernia surgery and 5/22 were found incidentally during appendectomy. Average operative time for unilateral and bilateral hernias was 22 minutes (5-38 minutes) and 31 minutes (11-65 minutes), respectively. No patient required a hospital stay because of the hernia repair. At an average of 25 months follow-up (1.6-75 months), there were no recurrences. The only complication was

Objective: To report a ventral abdominal approach and technique for laparoscopic bilateral ovariectomy in horses. Study Design: Prospective. Sample Population: Eleven mares and four mules, ranging in age from 5 months to 18 years were used in this study. Methods: A triangulation technique with a single laparoscopic portal and four instrument portals were used for ventral abdominal laparoscopic ovariectomy. Laparoscopic instruments were used to maneuver and secure each ovary through a ligating loop (modified Roeder knot) that was secured from outside the abdominal cavity. Minimal enlargement of one instrument portal was used to remove the ovaries. Results: Operative time, defined as the time from laparoscopic insertion to removal, ranged from 20 to 90 minutes. The mean operative time of the last seven animals was 26 minutes. Signs of estrus were observed in two mares within six months after ovariectomy. Conclusions: The reported technique allowed decreased tension on the tissues during ligation and removal of each ovary from the peritoneal cavity. Improved observation of the abdominal cavity, ligation security, shortened patient confinement time, and minimally invasive technique are all considered to be benefits of laparoscopic ovariectomy. Clinical Relevance: The ventral abdominal laparoscopic approach permitted efficient and safe ovariectomy in foals and adults.

Patients undergoing ventral hernia repair (VHR) with biologic mesh (BioM) have higher hospital costs compared with synthetic mesh (SynM). This study compares 90-d pre- and post-VHR hospital costs (180-d) among BioM and SynM based on infection risk. This retrospective National Surgical Quality Improvement Program study matched patient perioperative risk with resource utilization cost for a consecutive series of VHR repairs. Patient infection risks, clinical and financial outcomes were compared in unmatched SynM (n = 303) and BioM (n = 72) groups. Propensity scores were used to match 35 SynM and BioM pairs of cases with similar infection risk for outcomes analysis. BioM patients in the unmatched group were older with higher American Society of Anesthesiologists (ASA) and wound classification, and they more frequently underwent open repairs for recurrent hernias. Wound surgical site infections were more frequent in unmatched BioM patients (P = 0.001) as were 180-d costs ($43.8k versus $14.0k, P < 0.001). Propensity matching resulted in 31 clean cases. In these low-risk patients, wound occurrences and readmissions were identical, but 180-d costs remained higher ($31.8k versus $15.5k, P < 0.001). There were no differences in hospital 180-d diagnostic, emergency room, intensive care unit, floor, pharmacy, or therapeutic costs. However, 180-d operating room services and supply costs were higher in the BioM group ($21.1k versus $7.1k, P < 0.001). BioM is used more commonly in hernia repairs involving higher wound class and ASA scores and recurrent hernias. Clinical outcomes after low-risk VHRs are similar; SynM utilization in low-risk hernia repairs was more cost-effective. Published by Elsevier Inc.

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

The development of laparoscopic hernia repair has provided an alternative approach to the management of incarcerated inguinal hernia in children. Different laparoscopic techniques for hernia repair have been described. However, we hereby review the role of laparoscopic hernia repair using the hook method in the emergency setting for incarcerated inguinal hernias in children. A retrospective review was conducted of all children who presented with incarcerated inguinal hernia and underwent laparoscopic hernia repair using the hook method in emergency setting between 2004 and 2010. There were a total of 15 boys and 1 girl with a mean age of 30 ± 36 months (range, 4 months to 12 years). The hernia was successfully reduced after sedation in 7 children and after general anesthesia in 4 children. In 5 children, the hernia was reduced by a combined manual and laparoscopic-assisted approach. Emergency laparoscopic inguinal hernia repair using the hook method was performed after reduction of the hernia. The presence of preperitoneal fluid secondary to recent incarceration facilitated the dissection of the preperitoneal space by the hernia hook. All children underwent successful reduction and hernia repair. The median operative time was 37 minutes. There was no postoperative complication. The median hospital stay was 3 days. At a median follow-up of 40 months, there was no recurrence of the hernia or testicular atrophy. Emergency laparoscopic inguinal hernia repair by the hook method is safe and feasible. Easier preperitoneal dissection was experienced, and repair of the contralateral patent processus vaginalis can be performed in the same setting. Copyright © 2011 Elsevier Inc. All rights reserved.

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

Obturator hernia (OH), a rare cause of acute small bowel obstruction, requires immediate surgical intervention to prevent serious complications and mortality. We assessed the safety and efficacy of laparoscopic surgery in patients with incarcerated OH presenting with acute abdomen in an emergency setting. Data pertaining to patients diagnosed with incarcerated OH between 2011 and April 2015 at our hospital were reviewed. Patients' characteristics, operation details and postoperative outcomes were retrospectively analyzed. All ten patients diagnosed with incarcerated obturator hernia during the reference period were females (average age 72.1 ± 11.8 years; average weight 44.1 ± 6.9 kg; average body mass index 17.8 ± 2.1 kg/m(2); average operating time 63 ± 15 min; average hospital stay 6.2 ± 6.6 days). Twelve occult hernias, including six contralateral OHs, two ipsilateral femoral hernias and two bilateral femoral hernias were detected in six patients (60 %), which were simultaneously repaired after laparoscopic exploration. Nine patients (90 %) were successfully treated with synthetic mesh by laparoscopic technique. Only one case required intraoperative conversion to open surgery due to strangulated intestine with perforation. Wound infection was reported in one patient who had undergone bowel resection, but with an eventual complete recovery. Postoperative period was uneventful in the other nine patients. No recurrence or complications were reported on follow-up (mean duration of follow-up: 6-54 months). In this study, laparoscopic technique was associated with a reduced duration of hospital stay and fewer complications. In addition to being a safe and minimally invasive strategy, it allowed for simultaneous diagnosis and treatment of occult hernias during the same procedure. The approach may be a better option for the treatment of incarcerated OH and occult hernias in selected patients.

Ventral rectopexy to the promontory has become one of the most strongly advocated surgical treatments for patients with full-thickness rectal prolapse and deep enterocele. Despite its challenges, laparoscopic ventral rectopexy with or without robotic assistance for selected patients can be performed with relatively minimal patient trauma thus creating the potential for same-day discharge. The aim of this prospective case-controlled study was to assess the feasibility, safety, and cost of day case robotic ventral rectopexy compared with routine day case laparoscopic ventral rectopexy. Between February 28, 2014 and March 3, 2015, 20 consecutive patients underwent day case laparoscopic ventral rectopexy for total rectal prolapse or deep enterocele at Michallon University Hospital, Grenoble. Patients were selected for day case surgery on the basis of motivation, favorable social circumstances, and general fitness. One out of every two patients underwent the robotic procedure (n = 10). Demographics, technical results, and costs were compared between both groups. Patients from both groups were comparable in terms of demographics and technical results. Patients operated on with the robot had significantly less pain (p = 0.045). Robotic rectopexy was associated with longer median operative time (94 vs 52.5 min, p < 0.001) and higher costs (9088 vs 3729 euros per procedure, p < 0.001) than laparoscopic rectopexy. Day case robotic ventral rectopexy is feasible and safe, but results in longer operative time and higher costs than classical laparoscopic ventral rectopexy for full-thickness rectal prolapse and enterocele.

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.

The choice of the mesh and fixation methods in laparoscopic incisional hernia repair is a crucial issue in preventing complications and recurrence. The authors report a series of 40 consecutive laparoscopic incisional hernia repairs, focusing on the use of lightweight polypropylene mesh and on the way of mesh fixation. Forty laparoscopic incisional hernia repairs performed consecutively in 38 patients (16 males, 22 females) were retrospectively evaluated. Patients were divided into two groups depending on tacks used: Titanium tacks vs absorbable tacks. All patients received totally laparoscopic incisional hernia repair by the use of lightweight polypropylene mesh. No major post-operative complications were reported. Post-operative pain (evaluated by VNS) was higher in Group A (titanium tacks, p < 0.05). No differences in follow-up as well as in recurrence incidence (one case in both groups, <6 months time interval) were reported. Securestrap™ absorbable tacks are safe and effective and easy to use and did not increase the risk of mesh dislocation compared with non-absorbable tacks. The specific design well fits the lightweight polypropylene mesh Physiomesh™. Further evaluations in larger randomized studies are needed to confirm these preliminary data.

We used the database of the American College of Surgeons National Surgical Quality Improvement Program to (1) identify risk factors for 30-day venous thromboembolism (VTE) after ventral hernia repair (VHR) and (2) to create and validate a condition-specific assessment tool for the risk of VTE. Open and laparoscopic VHR patients in the American College of Surgeons National Surgical Quality Improvement Program were identified using Current Procedural Terminology code. The occurrence of VTE, including deep-venous thrombosis (DVT) or pulmonary embolus, within 30 days postoperatively was the primary outcome. Regression-based analysis and subsequent bootstrap analysis created a weighted VTE risk assessment model (RAM) for ventral hernia repair. The weighted RAM was used to risk-stratify patients for both 30-day VTE risk and 30-day risk for medical and surgical complications. Data for 113,873 hernia repair patients were obtained; 30-day deep-venous thrombosis, pulmonary embolus, and VTE rates were 0.59%, 0.43%, and 0.92%, respectively. The average time to VTE was 10.8 days. A 14-factor, weighted RAM was created. The weighted risk score identified a 25-fold variability (from 0.20 to 4.97%) in VTE risk among the overall VHR population. Although created to risk-stratify for VTE, the risk score also risk-stratified for 30-day medical and surgical complications, inpatient duration of stay, and 30-day mortality. The 30-day VTE risk after VHR is 0.92%, but a 25-fold variability in VTE risk exists among the overall hernia population. We demonstrate that a weighted VTE RAM quantifies VTE risk among the population undergoing ventral hernia repair, and that VTE risk score can also be used to risk-stratify for 30-day medical and surgical complications as well as mortality.

Component separation (CS) has become a viable alternative to repair large ventral defects when the fascia cannot be reapproximated. However, the impact of transecting the external oblique to facilitate closure of the abdomen on quality of life (QOL) has yet to be investigated. The study goal was to investigate QOL and outcomes after standard open ventral hernia repair (OVHR) versus CS for large ventral hernias. Prospective data for all CSs were reviewed and compared with matched OVHR controls. All defects were 100 to 1000 cm2 in size and repaired with mesh. Comorbidities, complications, outcomes, and Carolinas Comfort Scale (CCS) scores, were reviewed. Seventy-four CS patients were compared with 154 patients undergoing standard OVHR with similar defect sizes. Age (56.7±13.0 vs. 54.7 ± 12.3 years, P = .26), defect sizes (299 ± 160 vs. 304 ± 210 cm2, P = .87), and BMI (32.7 ± 6.9 vs. 34.2 ± 9.0 kg/m2, P = .26) were similar in both groups, respectively. There were no differences in major postoperative complications (P = .22), mesh infections (P = 1.00), wound infections (P = .07), or hernia recurrence (P = .09), but wound breakdown increased after CS (10% vs. 1%, P < .001) as did seroma interventions (15% vs. 4%, P = .005). Postoperative CCS scores were similar at 1 month (P = .82) and 1 year (P = .14). In the first comparative study of its kind, it is found that patient undergoing CS with mesh reinforcement had equal short- and long-term QOL outcomes compared with similar patients who underwent standard OVHR. Whereas wound breakdown and seroma formation are higher, the overall complication, mesh infection, and recurrence rates are similar.

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

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.

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 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.

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.

OBJECTIVE: Analysis of a staged management scheme for initial and definitive management of acute abdominal wall defects is provided. METHODS: A four-staged scheme for managing acute abdominal wall defects consists of the following stages: stage I--prosthetic insertion; stage II--2 to 3 weeks after prosthetic insertion and wound granulation, the prosthesis is removed; stage III--2 to 3 days later, planned ventral hernia (split thickness skin graft [STSG] or full-thickness skin and subcutaneous fat); stage IV--6 to 12 months later, definitive reconstruction. Cases were evaluated retrospectively for benefits and risks of the techniques employed. RESULTS: Eighty-eight cases (39 visceral edema, 27 abdominal sepsis, 22 abdominal wall resection) were managed during 8.5 years. Prostheses included polypropylene mesh in 45 cases, polyglactin 910 mesh in 27, polytetrafluorethylene in 10, and plastic in 6. Twenty-four patients died from their initial disease. The fistula rates associated with prosthetic management was 9%; no wound-related mortality occurred. Most wounds had split thickness skin graft applied after prosthetic removal. Definitive reconstruction was undertaken in 21 patients in the authors' institution (prosthetic mesh in 12 and modified components separation in 9). Recurrent hernias developed in 33% of mesh reconstructions and 11% of the components separation technique. CONCLUSIONS: The authors concluded that 1) this staged approach was associated with low morbidity and no technique-related mortality; 2) prostheses placed for edema were removed with fascial approximation accomplished in half of those cases; 3) absorbable mesh provided the advantages of reasonable durability, ease of removal, and relatively low cost--it has become the prosthesis of choice; and 4) the modified components separation technique of reconstruction provided good results in patients with moderate sized defects.

Laparoscopic ventral rectopexy can relieve symptoms of obstructed defecation and fecal incontinence in patients with rectoanal intussusception. However, pelvic floor imaging after surgery has not been reported. This study was designed to assess the outcome of patients who underwent laparoscopic ventral rectopexy for rectoanal intussusception, with special reference to the postoperative findings on evacuation proctography. This study was a retrospective analysis of prospectively collected data. The study was conducted from 2012 to 2013 at the Department of Surgery, Kameda Medical Center, Japan. We included 26 patients with symptomatic rectoanal intussusception. Laparoscopic ventral rectopexy was performed. Evacuation proctography was performed before and 6 months after the procedure. Defecatory function was evaluated using the Constipation Scoring System and Fecal Incontinence Severity Index. Of 26 patients with rectoanal intussusception preoperatively, 22 had symptoms of obstructed defecation and 21 complained of fecal incontinence. Postoperatively, rectoanal intussusception was eliminated in all patients, though 8 developed recto rectal intussusception. There was an overall reduction in both grade 2 rectocele size (median preop 26 mm vs. postop 11 mm; p < 0.0001) and pelvic floor descent (median preop 26 mm vs. postop 20 mm; p < 0.0001). 6 months after surgery, a reduction of at least 50% was observed in the Constipation Scoring System score for 9 patients (41%) with obstructive defecation and in the Fecal Incontinence Severity Index score for 14 incontinent patients (67%). This was a preliminary study with a small sample size, no control group, and short follow-up time. Evacuation proctography showed anatomical correction in patients with rectoanal intussusception who underwent laparoscopic ventral rectopexy. However, the data also indicate that such correction does not necessarily result in meaningful symptomatic relief.

Surgical site infection (SSI) after ventral incisional hernia repair (VIH) can result in serious consequences. We sought to identify patient, procedure, and/or hernia characteristics that are associated with SSI in VIH. Between 2004 and 2006, patients were randomized in four Veteran Affairs (VA) hospitals to undergo laparoscopic or open VIH. Patients who developed SSI within eight weeks postoperatively were compared to those who did not. A bivariate analysis for each factor and a multiple logistic regression analysis were performed to determine factors associated with SSI. The variables studied included patient characteristics and co-morbidities (e.g., age, gender, race, ethnicity, body mass index, ASA classification, diabetes, steroid use), hernia characteristics (e.g., size, duration, number of previous incisions), procedure characteristics (e.g., open versus laparoscopic, blood loss, use of postoperative drains, operating room temperature) and surgeons' experience (resident training level, number of open VIH previously performed by the attending surgeon). Antibiotic prophylaxis, anticoagulation protocols, preparation of the skin, draping of the wound, body temperature control, and closure of the surgical site were all standardized and monitored throughout the study period. Out of 145 patients who underwent VIH, 21 developed a SSI (14.5%). Patients who underwent open VIH had significantly more SSIs than those who underwent laparoscopic VIH (22.1% versus 3.4%; P = 0.002). Among patients who underwent open VIH, those who developed SSI had a recorded intraoperative blood loss greater than 25 mL (68.4% versus 40.3%; P = 0.030), were more likely to have a drain placed (79.0% versus 49.3%; P = 0.021) and were more likey to be operated on by surgeons with less than 75 open VIH case experience (52.6% versus 28.4%; P = 0.048). Patient and hernia characteristics were similar between the two groups. In a multiple logistic regression analysis, the open surgical technique was

Eleven mares and four mules were ovariectomized by a ventral abdominal laparoscopic technique. This approach required tilting the operative table about 30 degrees elevating the pelvis to allow observation of the ovaries. A triangulation technique with a single laparoscopic portal and four instrument portals was used. The ovarian pedicles were ligated and the ovaries were removed through a single enlarged instrument portal. Females ranged in age from 5 months to 18 years. Mean operative time was 44 minutes (range 20 to 90 minutes); mean operative time of the last seven animals was 26 minutes. Signs of abdominal pain occurred in three mules and one mare in the immediate postoperative period. Peritoneal fluid collected from six animals 48 hours after surgery had a mean leukocyte count of 34,463/microL: (range, 21,000 to 62,800/microL), mean protein concentration of 3.1 g/dL (range, 2.2 to 4.6 g/dL), and mean differential leukocyte count of 74% neutrophils and 26% mononuclear cells. The animals were confined for 2 weeks after surgery. Signs of estrus were observed in two mares within 6 months after ovariectomy. All owners reported satisfaction with the results of laparoscopic ovariectomy. The ventral abdominal laparoscopic approach permitted efficient and safe ovariectomy of foals and adults.

In large, long-term series of laparoscopic pediatric groin hernia repairs, the recurrence rate is commonly higher compared with the open herniotomy. Thus, we refined our laparoscopic technique from a simple hernia sac ligation into combined posterior wall repair for pediatric groin hernias. Between March 2010 and March 2013, 41 consecutive infants and children with primary inguinal hernia were treated surgically with our refined mini-laparoscopic hernia technique. The mean patient age was 4.5 years. Before hernia repair, there were synchronous bilateral hernias in 4 (9.7 %), left inguinal hernias in 14 (34.2 %) and right inguinal hernias in 23 (56.1 %). The mini-laparoscopic hernia repair was carried out with three 3.5 mm trocar ports including 3 mm telescope and 3 mm instruments. Totally 61 repairs were performed. The mean follow-up period was 12 months. The mean operation time was 45 min. None of the repaired groin hernias had a recurrence or procedure-related complication during the period of follow-up. None of them experienced a chronic pain postoperatively. To date there was no scrotal or testicular complication detected by regular ultrasonographic follow-up. Our refined laparoscopic technique is a safe and effective method in the management of groin hernias in infants and children with a minimal early recurrence rate.

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.

To inform a patient with penetrating thoracic trauma and diaphragm injury that produced stomach herniation, being reduced the hernia and repaired the injury by laparoscopy though abdominal route with excellent result. 17-years-old male, hemodynamically stable with penetrating injury in the fifth left intercostal space, at the level of the middle auxiliary line, pneumothorax and left diaphragmatic hernia. Treatment. A pleurostomy tube was inserted. By laparoscopy 600 mL of free blood in abdominal cavity were aspired, the stomach hernia was reduced and the diaphragmatic repair was performed with nylon 3-0 running suture. The evolution was excellent, being integrated to his work at the twentieth postoperative day. Our case supports that laparoscopic surgery is at therapeutic alternative in select cases of trauma.

Ventral hernias are often repaired after planned or unplanned bowel procedures. Biologic materials are thought to better tolerate gastrointestinal contamination than synthetic alternatives. The purpose of this review was to evaluate the impact of intestinal contamination on ventral hernia repair with biologic material. This is a retrospective review of all patients who underwent ventral hernia repair with biologic material between 2003 and 2012. Groups were defined based on performance of concomitant bowel surgery. Data were collected on patient demographics, risk factors, concomitant procedures, mesh type, and outcomes. Of 82 patients included in this series, 32 (39%) had concomitant bowel surgery. Ventral hernia repair was performed predominantly with Alloderm and Strattice. There was no difference in hernia recurrence (contaminated group-28% vs. non-contaminated group-34%, P = 0.58), surgical site infections (contaminated-28% vs. non-contaminated-20%, P = 0.40), or other complications when patients with and without concomitant bowel surgery were compared. Biologic materials have made it such that ventral hernias can be safely repaired after bowel surgery without increased risk of complications.

Incisional hernias are one of the most frequent complications of open abdominal surgery. Historically, the best results have been obtained with the open rives-stoppa approach. This is done by fixing a large piece of prosthetic mesh behind the rectus muscle. Laparoscopic approach allows similar mesh placement with minimal dissection and lower recurrence rate compared to the open mesh repair. Between October 2001 to September 2003, 75 consecutive patients were scheduled to undergo laparoscopic incisional hernia repair with ePTFE mesh (Gore-Tex Dualmesh Plus). Postoperative complications were recorded and analysed. Most were obese affected by multiple wall defects Conversion to open surgery was required in 1 case Postoperative complications occurred 13.3%. Recurrence occurred in one only case. The key to the success of this procedure is avoidance of complications. The laparoscopic approach is safe, effective and relatively complication-free option in the management of patients presenting with a first time or recurrent incisional hernia and recommended as the treatment of choice.

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.

There is evidence that mesh repair for primary umbilical hernias results in less recurrences and similar wound complication rates compared to tissue repair. In recent years, several mesh devices for the repair of small ventral hernias have been developed, but some reports have been published on serious complications and adverse effects encountered with those mesh devices. The Proceed™ Ventral Patch (PVP™) is a partially absorbable lightweight polypropylene mesh. We introduced PVP™ in our department in April 2009 and collected patient data and outcome in an observational study of 101 consecutive patients until December 2011 (Clinical.Trials.gov: NCT01307696). In addition to the routine control 3 weeks postoperative, prospective follow-up included a questionnaire, clinical investigation and ultrasound after 12 months. The study included 91 primary (76 umbilical/15 epigastric) and 10 incisional ventral hernias (including 6 trocar hernias). In all patients a PVP™ with a diameter of 6.4 cm was used. Wound problems were the most frequent complication (n = 18). Follow-up of at least 12 months was achieved in 98 patients (97 %) and the mean follow-up time was 15.9 months. Follow-up by clinical examination diagnosed a recurrence in 11/92 patients (12.0 %). Only four patients were aware of their recurrent hernia, the seven others reported no problems in the questionnaire. The additional ultrasound performed did not reveal recurrences that were not already diagnosed by clinical examination. In five patients a reoperation for repair of the recurrence was performed (reoperation rate 5/98 = 5.1 %). Hernia defect size (p = 0.032) and type of hernia (p = 0.029) were found to be a significant risk factors for development of a recurrent hernia (Fisher's exact test). Hernia size was a significant risk factor both in a univariate (p = 0.005) and in a multivariate Cox model (p = 0.017). Incisional hernia was of borderline significance in a univariate (p

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.

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

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.

Due to risks of postoperative morbidity and recurrence some patients with a ventral hernia are not offered surgical repair. There is limited data on the rate and consequences of a watchful waiting (WW) strategy for these patients. The objective of this cohort study was to analyse outcomes for patients with a ventral hernia who underwent watchful waiting, in terms of later requirement for hernia repair. All patients (≥18 years) electively referred to our out-patient clinic from 1 January 2009 to 1 July 2014 with incisional, umbilical or epigastric hernia were included. Information on patient characteristics and whether patients underwent WW or surgery was obtained from hospital files and the Danish National Patient Register. A 100% follow-up was obtained. The analyses comprised 569 patients with incisional hernia (WW = 58.1%) and 789 patients with umbilical/epigastric hernia (WW = 43.2%). Kaplan-Meier analyses estimated that the probability for patients who underwent watchful waiting to receive later surgical repair was 19 for incisional hernias and 16% for umbilical/epigastric hernias after 5 years. The probability of requiring emergency repair when in the WW group was 4% for both incisional and umbilical/epigastric hernias after 5 years. There were no significant differences in 30-day readmission, reoperation or mortality rates between the WW patients who later underwent elective hernia repair and patients who were initially offered surgery (p > 0.05), for both incisional and umbilical/epigastric hernias. Watchful waiting appears to be a safe strategy in the treatment of incisional, umbilical and epigastric hernias.

Sandwich ventral hernia repair (SVHR) may reduce ventral hernia recurrence rates, although with an increased risk of surgical site occurrences (SSOs) and surgical site infections (SSIs). Previously, we found that a modified negative pressure wound therapy (hybrid vacuum-assisted closure [HVAC]) system reduced SSOs and SSIs after ventral hernia repair. We aimed to describe our outcomes after SVHR paired with HVAC closure. We conducted a 4-y retrospective review of all complex SVHRs (biologic mesh underlay and synthetic mesh overlay) with HVAC closure performed at our institution by a single surgeon. All patients had fascial defects that could not be reapproximated primarily using anterior component separation. Descriptive statistics were used to report the incidence of postoperative complications and hernia recurrence. A total of 60 patients (59.3 ± 11.4 y, 58.3% male, 75% American Society of Anesthesiologists class ≥3) with complex ventral hernias being underwent sandwich repair with HVAC closure. Major postoperative morbidity (Dindo-Clavien class ≥3) occurred in 14 (23.3%) patients, but incidence of SSO (n = 13, 21.7%) and SSI (n = 4, 6.7%) was low compared with historical reports. Median follow-up time for all patients was 12 mo (interquartile range 5.8-26.5 mo). Hernia recurrence occurred in eight patients (13.3%) after a median time of 20.6 months (interquartile range 16.4- 25.4 months). Use of a dual layer sandwich repair for complex abdominal wall reconstruction is associated with low rates of hernia recurrence at 1 year postoperatively. The addition of the HVAC closure system may reduce the risk of SSOs and SSIs previously reported with this technique and deserves consideration in future prospective studies assessing optimization of ventral hernia repair approaches.

An increasing number of patients have large or complex abdominal wall defects. Component separation technique (CST) is a very effective method for reconstructing complex midline abdominal wall defects in a manner that restores innervated muscle function without excessive tension. Our goal is to show our results by a modified CST for treating large ventral hernias. A total of 351 patients with complex ventral hernias have been treated over a 10-year period. Pre- and postoperative CT scans were performed in all patients. All ventral hernias were W3, according to the EHS classification 1. We analyzed demographic variables, co-morbidities, hernia characteristics, operative, and postoperative variables. One hundred and seventy patients (48.4%) were men; the average age of the study population was 51.6 ± 23.2 years with an average BMI of 32.3 ± 1.3. The hernia was located in the midline in 321 cases (91.5%) versus the flank in 30 (8.5%). In 45 patients, preoperative botulinum toxin (BT) and progressive pneumoperitoneum (PPP) were needed due to giant hernia defects when the VIH/VAC ratio was >20%. Postoperative complications related to the surgical site were seroma (35.1%), hematoma (9.1%), infection (7.2%), and wound necrosis (8.8%). Complications related to the repair were evisceration in 3 patients (1.1%), small bowel fistula in 4 patients (1.5%), 11 cases of mesh infection (2.9%), and abdominal compartment syndrome (ACS) in 2 patients. There were 29 hernia recurrences (8.2%) with a mean follow-up of 31.6 ± 8.1 months. The modified CST is an effective strategy for managing complex ventral hernias that enables primary fascial closure with low rates of morbidity and hernia recurrence.

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

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

A pericecal hernia is a type of internal hernia, which rarely causes small bowel obstruction (SBO). At our institution, a 92-year-old man presented with vomiting and abdominal pain. He was conservatively treated with a diagnosis of SBO. After 2 weeks of copious drainage output, he was taken to the operating room. Laparoscopy revealed a pericecal hernia that was successfully reduced. We conclude that laparoscopic surgery is an effective way to treat SBOs secondary to pericecal hernias. PMID:26933000

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.

350 patients with medial ventral hernias were operated on. 307 of them had various concurrent diseases; 177 required simultaneous surgery on that account. Endoprosthesis (synthetic mesh) was fixed using an "inlay-sub-lay" technique. Local complications were detected in 19.4% of patients, 5.4% developed common complications. 1.1% of patients had died. Long-term hernia recurrence was registered in 1.1%.

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.

Despite improved operative techniques, open ventral hernia repair (VHR) surgery in high-risk, potentially contaminated patients remains challenging. As previously reported by our group, the use of a modified negative-pressure wound therapy system (hybrid-VAC or HVAC) in patients with grade 2 hernias is associated with lower surgical site occurrence (SSO) and surgical site infection (SSI) rates. Accordingly, the authors aim to evaluate whether the HVAC would similarly improve surgical site outcomes following VHR in patients with grade 3 hernias. A 4-year retrospective review (2011-2014) was conducted of all consecutive, modified ventral hernia working group (VHWG) grade 3 hernia repairs with HVAC closure performed by a single surgeon (FEE) at a single institution. Operative data and 90-day outcomes were evaluated. Overall outcomes (e.g., recurrence, reoperation, mortality) were reviewed for the study group. A total of 117 patients with an average age of 56.7 ± 11.9 years were classified as grade 3 hernias and underwent open VHR with subsequent HVAC closure. Fifty patients were male (42.7 %), the mean BMI was 35.2 (±9.5), and 60.7 % had a history of prior hernia repair. The average fascial defect size was 201.5 (±167.3) cm(2) and the mean length of stay was 14.2 (±9.3) days. Ninety-day outcomes showed an SSO rate of 20.7 % and an SSI rate of 5.2 %. The overall hernia recurrence rate was 4.2 % (n=6) with a mean follow-up of 11 ± 7.3 months. Modified VHWG grade 3 ventral hernias are associated with significant morbidity. In our series utilizing the HVAC system after VHR, the observed rate of SSO and SSI compared favorably to reported series. Further prospective cost-effective studies are warranted to validate these findings.

This study aims to examine the impact of laparoscopic repair of large hiatal hernia on dyspnoea severity, respiratory function and quality of life. From 2004 to 2008, 30 consecutive patients with large para-oesophageal hernia defined as >50% of stomach in the intra-thoracic cavity and minimum follow-up of 2 years were included in this study. All patients had a formal respiratory function test 1 week prior and 3 months after their laparoscopic hiatal hernia repair. Patients rated symptom severity and completed a quality-of-life questionnaire [Gastrointestinal Quality of Life Index (GIQLI)] pre-operatively, and post-operatively at 3 months, 6 months and yearly thereafter. There was no hospital mortality, and the morbidity rate was 10%. In 26 patients with pre-operative dyspnoea, 22 had complete resolution while the remaining 4 had improvement of dyspnoea severity post-operatively. The mean dyspnoea severity index reduced from 2.4 to 1.3 (P < 0.001). Overall, there was 1%, 3% and 3% post-operative increase in forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC) and diffusing capacity of the lung for carbon monoxide (DLCO) values for the whole group, none of which reached statistical significance. For patients with resolution or improvement of dyspnoea after laparoscopic repair, no significant change of respiratory function parameters was demonstrated. GIQLI score improved from a pre-operative value of 85.7 to 107.9 post-operatively (P < 0.001). We failed to show a significant change in post-operative respiratory function despite clearly demonstrated improvement of respiratory symptoms. Alternative explanations for reduction of dyspnoea severity should be sought.

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 belief that irreducible hernias are repaired less successfully and with higher morbidity drives patients to seek elective repair. The aims of this study were threefold. First, this study sought to compare characteristics of patients undergoing irreducible and reducible ventral hernia repair. Second, to compare morbidity rates. Third, to determine which factors, including irreducibility, might be associated with recurrence. This observational study was a retrospective review of 252 consecutive ventral hernia patients divided into two cohorts: 101 patients who underwent repair of an irreducible ventral hernia, and 152 patients underwent repair of a reducible ventral hernia. The mean follow-up time was approximately 4 years in both groups. Patients undergoing repair of irreducible hernias had higher median BMI (31 vs. 27 kg/m2, p = 0.005), had their hernias longer (median 34 months compared to 12 months, p = 0.043), had more defects on average (mean 1.8 vs. 1.4, p < 0.001), and were more likely to be symptomatic (83 vs. 55%, p = 0.002). Interestingly, neither hernia size (p = 0.821), nor the location of hernia (p = 0.261) differed significantly between the two groups. Morbidity rates, including rates of surgical site infection, obstruction, and recurrence, did not differ significantly; nor did recurrence-free survival (RFS) distributions. Risk factors for hernia recurrence on multivariate analysis included the repaired hernia being itself recurrent (HR = 2.06, 95% CI = 1.07-3.99, p = 0.031), the occurrence of post-operative surgical site infection (HR = 5.10, 95% CI = 2.18-11.91, p < 0.001), and the occurrence of post-operative intestinal obstruction (HR = 5.18, 95% CI = 1.82-14.75, p = 0.002). Irreducibility was not a significant predictor of recurrence (p = 0.152). Despite differing profiles, patients with these two types of hernias did not have statistically significant differences in morbidity. Recurrence was not observed to be associated with irreducibility

Obturator hernia is a rare clinical condition that causes intestinal obstruction. Recent reports have suggested that laparoscopic repair may be useful for incarcerated obturator hernia in select patients. The patient was a 64-year-old female who presented to our emergency department with a chief complaint of abdominal pain. Computed tomography (CT) imaging revealed an incarcerated obturator hernia on her right side, without apparent findings of irreversible ischaemic change or perforation. She had a previous history of cardiovascular surgery and was taking an anticoagulant medication. We performed a reduction of the incarcerated intestine. After heparin displacement, laparoscopic repair was electively performed. During laparoscopy, an occult obturator hernia was found on the left side. We repaired the bilateral obturator hernia using a mesh prosthesis. Elective laparoscopic repair after reduction might be a useful procedure for incarcerated obturator hernias in those patients without findings of irreversible ischaemic change or perforation.
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

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

Abdominal wall hernias are a common problem. The success of abdominal wall reconstruction decreases with increasing hernia size. This study summarizes the outcomes of one surgeon's experience using a "sandwich" technique for hernia repair in patients with loss of abdominal domain. We reviewed our ventral hernia repair (VHR) experience from 2008 to 2015 among patients with loss of domain, as defined by a hernia defect greater than 300 cm(2). The percent of herniation through the defect, defined by a hernia sac-to-abdominal cavity volume ratio, was measured on preoperative CT scans by four independent reviewers and averaged. Outcomes were compared among those with giant ventral hernias (hernia sac-to-abdominal cavity volume >30%) and those with smaller defect ratios. Over the study period, 21 patients underwent VHR. In 17 patients (81%), a "sandwich" technique was utilized. Ten patients had hernia sac-to-abdominal cavity defects less than 30%, and 11 had defects greater than 30%. Preoperative characteristics were similar in both groups with the exception of a higher ASA score in those with giant ventral hernias and more Ventral Hernia Working Group Grade 3 hernias in those without giant ventral hernias. Postoperative outcomes were similar in both groups. There were no mortalities. There were two recurrences (18%) in the giant VHR group and none in the smaller defect group (p = 0.16). Surgical site occurrences were noted in 48% of patients and did not differ between giant and non-giant VHR groups (50 vs 45%, p = 0.84). Average postoperative length of stay was significantly longer in the giant VHR group (31 vs. 17 days, p = 0.03). Our results suggest that the "sandwich" technique for VHR is a safe and durable method to restore abdominal wall integrity in those with LOD, even in patients with giant ventral hernias.

The selection of a laparoscopic approach for inguinal hernias varies among surgeons. It is unclear what is being done in actual practice. The purpose of this study was to report practice patterns for treatment of inguinal hernias among Quebec surgeons, and to identify factors that may be associated with the choice of operative approach. We studied a population-based cohort of patients who underwent an inguinal hernia repair between 2007 and 2011 in Quebec, Canada. A generalized linear model was used to identify predictors associated with the selection of a laparoscopic approach. 49,657 inguinal hernias were repaired by 478 surgeons. Laparoscopic inguinal hernia repair (LIHR) was used in 8 % of all cases. LIHR was used to repair 28 % of bilateral hernias, 10 % of recurrent hernias, 6 % of unilateral hernias, and 4 % of incarcerated hernias. 268 (56 %) surgeons did not perform any laparoscopic repairs, and 11 (2 %) surgeons performed more than 100 repairs. These 11 surgeons performed 61 % of all laparoscopic cases. Patient factors significantly associated with having LIHR included younger age, fewer comorbidities, bilateral hernias, and recurrent hernias. An open approach is favored for all clinical scenarios, even for situations where published guidelines recommend a laparoscopic approach. Surgeons remain divided on the best technique for inguinal hernia repair: while more than half never perform LIHR, the small proportion who perform many use the technique for a large proportion of their cases. There appears to be a gap between the best practices put forth in guidelines and what surgeons are doing in actual practice. Identification of barriers to the broader uptake of LIHR may help inform the design of educational programs to train those who have the desire to offer this technique for certain cases, and have the volume to overcome the learning curve.

Morgagni hernia is a rare type of diaphragmatic hernia. Though in the past, it has been dealt with an open approach, nowadays laparoscopic management is a favored approach. However, there are few controversies in this scenario. We present here two females of Aryan ethnicity, one 55 and another 45 years old, who presented with pain at upper abdomen and retrosternal chest pain; on investigations were found to have cholelithiasis along with Morgagni hernia which were managed via the laparoscopic approach in the same sitting. Repair of Morgagni hernia also via the minimally invasive technique can be offered to the patients like that for cholelithiasis.

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.

The Global Operative Assessment of Laparoscopic Skills (GOALS) is a valid and reliable measure of basic, non-procedure-specific laparoscopic skills. GOALS-incisional hernia (GOALS-IH) was developed to evaluate performance of laparoscopic incisional hernia repair (LIHR). The purpose of this study was to assess the validity and reliability of GOALS-IH during LIHR simulation. GOALS-IH assesses 7 domains with a maximum score of 35. A total of 12 experienced surgeons and 10 novices performed LIHR on the Surgical Abdominal Wall simulator. Performance was assessed by a trained observer and by self-assessment using GOALS-IH, basic GOALS and a visual analog scale (VAS) for overall competence. Both interrater reliability and internal consistency were high (.76 and .95 respectively). Experienced surgeons had higher mean GOALS-IH scores than novices (32.3 ± 2 versus 22.7 ± 5). There was excellent correlation between GOALS-IH and other measures of performance (GOALS r = .93 and VAS r = .93). GOALS-IH is easy to use, valid and reliable for assessment of simulated LIHR.

Perineal hernia is a rare complication following laparoscopic abdominoperineal resection (APR) for rectal cancer. We present two case reports of perineal hernia following laparoscopic APR and discuss their management. We suggest that they developed because the pelvic peritoneum was left open during laparoscopic APR and propose that closure of the pelvic peritoneum should be routine in this operation. PMID:24780656

Two fundamental biological differences between normal fascia and scar tissue are rate of collagen turnover and physical weave of collagen subunits. Both factors account for unsatisfactory results following ventral hernia repair unless scar tissue is excised and normal fiscia used. Removal of scar and identification of normal fascia often require extensive dissection, entrance into the peritoneal cavity, and sometimes requires lysis of intestinal adhesions with occasional injury to bowel. Simple imbrication of the hernia sac, as in treatment of a direct inguinal hernia, without excision usually results in recurrence of the hernia because of remodeling and attenuation of scar tissue. A new procedure, based upon the technique of direct inguinal hernia repair without opening peritoneum, has been performed on 12 patients with large ventral hernias. The procedures, performed entirely in a subcutaneous plane, involves imbrication of scar, transfer of a massive fascial onlay graft, and use of an internal stent. Patients have been followed for one to 5 years; there have been no recurrences. Inductive influence of the fascial transplant has been measured in two patients; a tenfold increase in net collagen synthesis and deposition occurs for at least one year following transplantation of fascia to an imbricated scar recipient area.

Surgical repair of recurrent abdominal incisional hernia(s) can be challenging due to complex operative conditions, intense post-operative pain, potential respiratory compromise and lateral muscle traction predisposing to early recurrence. We report our preliminary results with botulinum toxin A (BTA) injection causing flaccid paralysis (relaxation) of the lateral abdominal wall muscles prior to surgery. A prospective pilot study measured the effect of preoperative BTA prior to elective repair of recurrent abdominal hernias. Under ultrasound control, 2 weeks prior to surgery, 50 units of BTA was injected into the external oblique, internal oblique and transversus abdominis muscles at three sites on each side of the lateral abdominal wall (total dose 300 units). Pre- and post-BTA abdominal computed tomography measured changes in abdominal wall muscle thickness and length. All hernias were repaired with laparoscopic or laparoscopic-assisted mesh techniques in a single or two-staged procedure. Eight patients received BTA injections which were tolerated with no complications. Post-BTA preoperative computed tomography showed a significant increase in mean length of lateral abdominal wall from 18.5 cm pre-BTA to 21.3 cm post-BTA (P = 0.017) with a mean unstretched length gain of 2.8 cm per side (range 0.8-6.0 cm). All hernias were surgically reduced with mesh with no early recurrence. Preoperative BTA injection prior to complex abdominal hernia repair is a safe procedure that causes flaccid relaxation, elongation and thinning of the lateral abdominal muscles and decrease in hernia defect. Although further evaluation is required, BTA injections may be a useful adjunct to surgical repair of complex incisional hernias. © 2015 Royal Australasian College of Surgeons.

Mesh reinforcement can reduce hernia recurrence, but mesh selection is poorly understood, particularly in contaminated defects. Acellular dermal matrix has enabled single-stage ventral hernia repair in clean-contaminated wounds but can be associated with higher complications and cost compared with synthetic mesh. This study evaluated the cost-utility of synthetic mesh and acellular dermal matrix for clean-contaminated ventral hernia repairs. A systematic review of articles comparing outcomes for synthetic and acellular dermal matrix repairs identified 14 ventral hernia repair-specific health states. Quality-adjusted life years were determined through Web-based visual analog scale survey of 300 nationally representative individuals. Overall expected cost and quality-adjusted life-years for ventral hernia repair were assessed using a Monte Carlo simulation with sensitivity analyses. Synthetic mesh reinforcement had an expected cost of $15,776 and quality-adjusted life-year value gained of 21.03. Biological mesh had an expected cost of $23,844 and quality-adjusted life-year value gained of 20.94. When referencing a common baseline (do nothing), acellular dermal matrix (incremental cost-effectiveness ratio, 3378 ($/quality-adjusted life years)) and synthetic mesh (incremental cost-effectiveness ratio, 2208 ($/quality-adjusted life years)) were judged cost-effective, although synthetic mesh was more strongly favored. Monte Carlo sensitivity analysis demonstrated that synthetic mesh was the preferred and most cost-effective strategy in 94 percent of simulations, supporting its overall greater cost-utility. Despite varying the willingness-to-pay threshold from $0 to $100,000 per quality-adjusted life-year, synthetic mesh remained the optimal strategy across all thresholds in sensitivity analysis. This cost-utility analysis suggests that synthetic mesh repair of clean-contaminated hernia defects is more cost-effective than acellular dermal matrix.

Purpose The aim of this study was to evaluate the surgical outcomes of laparoscopic approach for hiatal hernia (HH) in pediatric patients. Methods This was a retrospective study of 33 patients younger than 18 years who underwent an operation for HH between January 1999 and December 2012. Results The HH symptoms were various and included regurgitation, vomiting, weight loss, cough, hoarseness, and cyanosis. Among the 33 patients, there were 25 sliding types, 1 paraesophageal type, and 7 mixed types. Open surgery (OS) and laparoscopic surgery (LS) were used in 16 and 17 patients, respectively. There were no statistically significant differences in sex, age, or body weight between the groups. The median operating time was longer in the LS group (150 minutes; range, 90-250 minutes vs. 125 minutes; range, 66-194 minutes; P = 0.028). Time to oral intake was shorter in the LS group than in the OS group (1 day; range, 1-3 days vs. 2 days; range, 1-7 days; P = 0.001) and time to full feeding was shorter in the LS group than in the OS group (6 days; range, 3-16 days vs. 10 days; range, 3-33 days; P = 0.048). There were no differences in length of hospital stay and complications between the two groups. There was no perioperative mortality or recurrence of HH. Conclusion A good surgical outcome for laparoscopic correction of HH was seen in pediatric patients. PMID:24851228

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 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

Hiatal hernia is a common disorder and a controversial topic. In symptomatic voluminous hernias laparoscopic surgery and use of mesh can be considered. An initial experience in voluminous hiatal hernia laparoscopic repair using absorbable glycolic acid/trimethylene carbonate synthetic mesh is reported. Retrospective study from an institutional database was performed to analyze laparoscopic hiatal hernia repair using absorbable synthetic mesh from January 2010 to December 2013. All preoperative symptoms and exams were collected and a standardized procedure was performed. Clinical and radiological follow-up was performed. Eight patients underwent laparoscopic repair of hiatal hernia performed by two highly skilled laparoscopic surgeons. One Toupet and seven Nissen fundoplications were tailored. No conversions into laparotomy, neither intraoperative complications nor mortality occurred. After a median follow-up of 23.5 months (range 14 - 44) no mesh complications occurred and all patients are asymptomatic. Two radiological recurrences (25%) were detected. Voluminous symptomatic hiatal hernias can be successfully treated in a high-volume and long-term experienced laparoscopic surgical center by the use of an absorbable synthetic mesh. Further studies and a longer-term follow-up are necessary to confirm this preliminary report.

Little is known about the clinical or patient-reported outcomes with non-operative management of ventral hernias. The aim of this prospective study is to determine the clinical and patient-reported outcomes of patients undergoing initial non-operative treatment of their ventral hernia. This was a prospective observational study of patients undergoing non-operative management of ventral hernias. Primary outcome was rate of surgical repair of the ventral hernias. Secondary outcomes included rate of emergency repair, elective repair, and emergency room visits. In addition, validated measurement tools for patient satisfaction and cosmetic satisfaction with their abdomen, abdominal pain, and patient function (modified Activities Assessment Scale, AAS) were utilized. Of 128 patients who underwent non-operative management of a ventral hernia, 99(77.3%) patients were followed for a median (interquartile range) of 12.2(10.4-13.5) months. Twenty (20.2%) patients had at least 1 emergency room visit associated with their hernia. One-quarter (n = 2323.2%) underwent ventral hernia repair following enrollment. Twenty (20.2%) underwent elective repair, and 3 (3.0%) underwent emergent repair. Based on the modified AAS survey, patients who were managed non-operatively experienced no change in patient centered outcomes, while patients converted to operative management had improved scores. While the short-term risk of emergency surgery with non-operative management of ventral hernias is moderate, the chance of an emergency room visit and surgery is high. Patients who undergo non-operative management of their ventral hernias have no change in patient-reported outcomes at one year, while those converted to operative management experience improvement.

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. 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

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.

There is varying evidence about the use of preoperative chlorhexidine gluconate to decrease surgical site infection for elective surgery. This intervention has never been studied in ventral hernia repair, the most common general surgery procedure in the US. We aimed to determine whether preoperative chlorhexidine gluconate decreases the risk of 30-day wound morbidity in patients undergoing ventral hernia repair. All patients undergoing ventral hernia repair in the Americas Hernia Society Quality Collaborative were separated into 2 groups: 1 group received preoperative chlorhexidine scrub and the other did not. The 2 groups were evaluated for 30-day wound morbidity, including surgical site occurrence (SSO), surgical site infection (SSI), and SSO requiring procedural intervention. Statistical analysis was performed using multivariate regression analysis and propensity score modeling. Multiple factors were controlled for statistical analysis, including patient-related factors and operative factors. In total, 3,924 patients were included for comparison. After multivariate logistic regression modeling, the preoperative chlorhexidine scrub group had a higher incidence of SSOs (odds ratio [OR] = 1.34; 95% CI 1.11 to 1.61) and SSIs (OR = 1.46; 95% CI 1.03 to 2.07). After propensity score modeling, the increased risk of SSO and SSI persisted (SSO: OR = 1.39; 95% CI 1.15 to 1.70; SSI: OR = 1.45; 95% CI 1.011 to 2.072, respectively). Prehospital chlorhexidine gluconate scrub appears to increase the risk of 30-day wound morbidity in patients undergoing ventral hernia repair. These findings suggest that the generalized use of prehospital chlorhexidine might not be desirable for all surgical populations. Copyright Â© 2016 American College of Surgeons.

To assess the integrity of hernia repair, imaging modalities such as computed tomography or ultrasound (US) are commonly used. Neither modality has currently the capacity to simultaneously image the mesh and quantify a prosthetic and surrounding tissue stiffness. In this pilot study, we hypothesize that US shear wave elastography (SWE) can be used to identify a polyester mesh and a biologic graft and to assess their stiffness noninvasively in a rat model of bridging hernia repair. Lewis rats underwent hernia creation and repair with Parietex or Strattice at 30 d. After 3 mo, the animals were euthanized, and the Young's Modulus was measured using SWE. Three-dimensional reconstructions of the hernia pre- and post-repair were performed using in-house image processing algorithms. SWE was capable of accurate and real-time assessment and diagnosis of the hernia defects in vivo. Young's Modulus of Parietex meshes and Strattice grafts as estimated from the shear wave elastograms were found to be statistically different from each other (P < 0.05). Accurate three-dimensional reconstructions of the hernia defects pre- and post-repair were generated. In this study, we demonstrate the feasibility of using US SWE to detect ventral hernias and evaluate mesh repair in vivo. Our results indicate that the presence of a hernia and repair can be reliably visualized by SWE and three dimensionally reconstructed. Thus, this technique may provide both structural and functional information regarding the hernia and the repair. Copyright © 2016 Elsevier Inc. All rights reserved.

Bochdalek hernia (BH) is an uncommon form of diaphragmatic hernia. The rarity of this hernia and its nonspecific presentation leads to delay in the diagnosis, with the potential risk of complications. This review summarizes the relevant aspects of its presentation and management, based on the present evidence in the literature. A literature search was performed on PubMed, Google Scholar, and EMBASE for articles in English on BH in adults. All case reports and series from the period after 1955 till January 2015 were included. A total of 180 articles comprising 368 cases were studied. The mean age of these patients was 51 years (range 15-90 years) with a male preponderance of 57% (211/368). Significantly, 6.5% of patients were above 70 years, with 3.5% of these being above 80 years. The majority of the hernias were on the left side (63%), with right-sided hernias and bilateral occurring in 27% and 10%, respectively. Precipitating factors were noted in 24%, with 5.3% of them being pregnant. Congenital anomalies were seen in 11%. The presenting symptoms included abdominal (62%), respiratory (40%), obstructive (vomiting/abdominal distension; 36%), strangulation (26%); 14% of them were asymptomatic (detected incidentally). In the 184 patients who underwent surgical intervention, the surgical approach involved laparotomy in 74 (40.27%), thoracotomy in 50 (27.7%), combined thoracoabdominal approach in 27 (14.6%), laparoscopy in 23 (12.5%), and thoracoscopic repair in 9 (4.89%). An overall recurrence rate of 1.6% was noted. Among these patients who underwent laparoscopic repair, 82% underwent elective procedure; 66% underwent primary repair, with 61% requiring interposition of mesh or reenforcement with or without primary repair. The overall mortality was 2.7%. Therefore, BH should form one of the differential diagnoses in patients who present with simultaneous abdominal and chest symptoms. Minimal access surgery offers a good alternative with short hospital stay and is

Approximately one fifth of patients suffer from inguinal pain after laparoscopic total extraperitoneal (TEP) inguinal hernia repair. There is existing literature suggesting that the staples used to fix the mesh can cause postoperative inguinal pain. In this study, we describe our experience with laparoscopic TEP inguinal hernia surgery using 3-dimensional mesh without mesh fixation, in our institution. A total of 300 patients who had undergone laparoscopic TEP inguinal hernia repair with 3-dimensional mesh in VKV American Hospital, Istanbul from November 2006 to November 2015 were studied retrospectively. Using the hospital's electronic archive, we studied patients' selected parameters, which are demographic features (age, sex), body mass index, hernia locations and types, duration of operations, preoperative and postoperative complications, duration of hospital stays, cost of surgery, need for analgesics, time elapsed until returning to daily activities and work. A total of 300 patients underwent laparoscopic TEP hernia repair of 437 inguinal hernias from November 2006 to November 2015. Of the 185 patients, 140 were symptomatic. Mean duration of follow-up was 48 months (range, 6 to 104 mo). The mean duration of surgery was 55 minutes for bilateral hernia repair, and 38 minutes for unilateral hernia repair. The mean duration of hospital stay was 0.9 day. There was no conversion to open surgery. In none of the cases the mesh was fixated with either staples or fibrin glue. Six patients (2%) developed seroma that were treated conservatively. One patient had inguinal hernia recurrence. One patient had preperitoneal hematoma. One patient operated due to indirect right-sided hernia developed right-sided hydrocele. One patient had wound dehiscence at the umbilical port entry site. Chronic pain developed postoperatively in 1 patient. Ileus developed in 1 patient. Laparoscopic TEP inguinal repair with 3-dimensional mesh without mesh fixation can be performed as safe as

A 12-year-old female presented with the abnormal findings on the chest PA. The chest CT revealed a retrosternal defect of the diaphragm and a fatty opacity in the pleural cavity, resulting in a diagnosis of Morgagni hernia. It was decided to undergo a laparoscopic surgery. The retrosternal defect of the diaphragm measuring 3.5 cm in diameter was found, through which a portion of the greater omentum and the fatty tissue connected with the falciform ligament were herniated into the pleural cavity. The greater omentum was pushed back into the peritoneal cavity and the fatty tissue connected with falciform ligament was excised. The mediastinal pleura was plicated and the defect of the diaphragm was repaired primarily. Immediately after the operation, the patient developed a right pneumothorax for which a chest tube was inserted. She was discharged at the post-operative third day without any further complications.

The role of surgical adhesives in hernia repair has continued to evolve. The purpose of this chapter is to review the role of fibrin sealant and its application in general surgery for mesh fixation, specifically the history, biomechanics, and clinical utilization. The utilization of fibrin sealant for repair of groin hernias, both open and laparoscopic, ventral hernias, and hiatal hernias will be discussed.

Recurrence after ventral hernia repair (VHR) remains a multifactorial problem still plaguing surgeons today. Some of the many contributing factors include mechanical strain, poor tissue-mesh integration, and degradation of matrices. The high recurrence rate witnessed with the use of acellular dermal matrices (ADM) for definitive hernia repair has reduced their use largely to bridging repair and breast reconstruction. Modalities that improve classic cellular metrics of successful VHR could theoretically result in improved rates of hernia recurrence; autologous platelet-rich plasma (PRP) may represent one such tool, but has been underinvestigated for this purpose. Lewis rats (32) had chronic ventral hernias created surgically and then repaired with Strattice™ mesh alone (control) or mesh + autologous PRP. Samples were harvested at 3 and 6 months postoperatively and compared for gross, histologic, and molecular outcomes of: neovascularization, tissue incorporation, peritoneal adhesions, hernia recurrence, and residual mesh thickness. Compared to control at 3 months postoperatively, PRP-treated rats displayed significantly more neovascularization of implanted mesh and considerable upregulation of both angiogenic genes (vEGF 2.73-fold, vWF 2.21-fold) and myofibroblastic genes (αSMA 9.68-fold, FSP-1 3.61-fold, Col1a1 3.32-fold, Col31a1 3.29-fold). Histologically, they also showed enhanced tissue deposition/ingrowth and diminished chronic immune cell infiltration. Peritoneal adhesions were less severe at both 3 (1.88 vs. 2.94) and 6 months (1.63 vs. 2.75) by Modified Hopkins Adhesion Scoring. PRP-treated rats experienced decreased hernia recurrence at 6 months (0/10 vs. 7/10) and had significantly improved ADM preservation as evidenced by quantification of residual mesh thickness. PRP is an autologous source of pro-regenerative growth factors and chemokines uniquely suited to soft tissue wound healing. When applied to a model of chronic VHR, it incites enhanced

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.

Lumbar hernias are rare. Usually manifest with reducible volume increase in the post-lateral region of the abdomen and may occur in two specific anatomic defects: the triangles of Grynfelt (upper) and Petit (lower). Despite controversies with better repair, laparoscopic approach, following the same principle of the treatment of inguinal hernias, seems to present significant advantages compared to conventional/open surgeries. However, some technical and anatomical details of the region, non usual to general surgeons, are fundamental for proper repair. To present systematization of laparoscopic transabdominal technique for repair of lumbar hernias with emphasis on anatomical details. : Patient is placed in the lateral decubitus. Laparoscopic access to abdominal cavity is performed by open technique on the left flank, 1.5 cm incision, followed by introduction of 11 mm trocar for a 30º scope. Two other 5 mm trocars, in the left anterior axillary line, are inserted into the abdominal cavity. The peritoneum of the left paracolic gutter is incised from the 10th rib to the iliac crest. Peritoneum and retroperitoneal is dissected. Reduction of all hernia contents is performed to demonstrate the hernia and its size. A 10x10 cm polypropylene mesh is introduced into the retroperitoneal space and fixed with absorbable staples covering the defect with at least 3-4 cm overlap. Subsequently, is carried out the closure of the peritoneum of paracolic gutter. This technique was used in one patient with painful increased volume in the left lower back and bulging on the left lumbar region. CT scan was performed and revealed left superior lumbar hernia. Operative time was 45 min and there were no complications and hospitalization time of 24 h. As in inguinal hernia repair, laparoscopic approach is safe and effective for the repair of lumbar hernias, especially if the anatomical details are adequately respected.

The individual characteristics of the structure of the anterior abdominal wall were studied for revealing the anatomical preconditions for the formation of postoperative ventral hernias in order to substantiate efficient methods of surgical treatment. It was established that patients with brachiomorphous build had anatomical features facilitating the formation of ventral hernias. The greatest strength of the fascio-aponeurotic complex of the anterior abdominal wall is characteristic of patients with a dolichomorphous constitution, while the least strength of the fascio-aponeurotic complex of the anterior abdominal wall is characteristic of patients with brachiomorphous constitution. Patients with the dolicho- and mesomorphous constitution having postoperative ventral hernias can undergo plasty of the hernial gates with the local tissues. Patients with brachiomorphous constitution after elimination of the postoperative ventral hernias need the strengthening of the anterior abdominal wall with cellular explants.

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.

biocompatibility to function as suitable ventral hernia repair mesh, while offering a reduction in surgical operating time and improving mesh placement characteristics. Future work will include ball-burst tests similar to ASTM D3787-07, direct surgeon feedback studies, and a 30 day chronic porcine model to evaluate the SMP surgical mesh in a realistic hernia repair environment, using laparoscopic techniques for typical ventral hernia 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

From the patient's perspective, a ventral hernia (VH) can cause pain, adversely affect function, increase size, cosmetically distort the abdomen, and incarcerate/strangulate abdominal contents. The only known "cure" for a VH is surgical repair. The aim of this study was to review systematically the published randomized controlled trials (RCTs) of the surgical care of VH. A search of the Ovid, MEDLINE, EMBASE, and Cochrane databases was performed to obtain reports of RCTs on the use of mesh reinforcement in abdominal wall hernia repair. The outcomes assessed were hernia recurrence and surgical site infection (SSI). The overall quality of evidence was assessed using Grading of Recommendations Assessment, Development, and Evaluation (GRADE). When feasible, based on assessment of heterogeneity, data were pooled and analyzed in a meta-analysis. Of the 10,349 titles screened, 25 articles (23 studies) met the search criteria. Evidence indicates that mesh reinforcement in clean cases can decrease hernia recurrence (number needed to treat = 7.9) but increase risk of SSI (number needed to harm = 27.8). Placing mesh in the sublay position (as opposed to the onlay or underlay position) may decrease the risk of hernia recurrence and SSI. Mesh reinforcement is recommended for all VH repairs in a clean case (high grade of evidence). Sublay mesh location may result in fewer recurrences and SSIs than onlay or inlay placement, but further study is needed to confirm this hypothesis (moderate grade of evidence).

The authors report their preliminary experience in laparoscopic repair of associated inguinal and umbilical hernias in children. Twenty-six patients affected by the association of inguinal and umbilical hernia with an umbilical defect larger than 5 mm underwent a laparoscopic procedure. A 5-mm trocar was placed through the umbilical defect for the optic. To fix the trocar to avoid loss of carboperitoneum, we fashioned and tightened a purse-string non-absorbable suture with a sliding knot around the defect. In this manner, we ensured the trocar, fixing it and avoiding any loss of CO2, proceeding safely to the laparoscopic IH repair, by means of two additional 3 mm operative trocars. At the end of the inguinal herniorrhaphy, the previously fashioned purse-string suture was tightened to repair the umbilical defect. The mean operative time for the repair of associated inguinal and umbilical hernias was 30.1 ± 7.4 min in cases of unilateral inguinal hernia and 39.5 ± 10.6 for bilateral inguinal hernia. Follow-up ranged from 8 to 32 months. Neither intra- nor post-operative complications nor recurrences were seen. This small sample suggests that this simple method is safe, effective and might be useful for pediatric surgeons performing laparoscopic repair for inguinal hernia in presence of an associated UH with a statistically significant decrease of operative time.

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.

Ventral incisional hernia (VIH) is not uncommon following liver transplantation. Open repair was traditionally adopted for its management. Laparoscopic repair of VIH has been performed successfully in nontransplant patients with evidence of reduced recurrence rates and hospital stay. However, the application of VIH in post-transplantation patients has not been well established. Herein, we provide our initial experience with laparoscopic repair of post-transplantation VIH. From March 2015 to March 2016, 18 cases of post-transplantation VIH were subjected to laparoscopic repair (laparoscopy group). A historical control group of 17 patients who underwent conventional open repair (open group) from January 2013 to January 2015 were identified for comparison. The demographics and clinical outcomes were retrospectively compared. There were no significant differences among basic demographics between the 2 groups. No conversion was recorded in the laparoscopy group. Recurrence of VIH up to the end of the study period was not noted. In the laparoscopy group, the minor complications were lower (16.7% vs 52.9%; P = .035), the length of hospital stay was shorter (3 d vs 7 d, P = .007), but the median operative time was longer (137.5 min vs 106 min; P = .003). Laparoscopic repair of post-transplantation VIH is a safe and feasible procedure with shorter length of hospital stay. Copyright © 2017 Elsevier Inc. All rights reserved.

Inguinal hernia repair is one of the most commonly performed operations in the pediatric population. While the majority of pediatric surgeons routinely use laparoscopy in their practices, a relatively small number prefer a laparoscopic inguinal hernia repair over the traditional open repair. This article provides an overview of the three port laparoscopic technique for inguinal hernia repair, as well as a review of the current evidence with respect to visualization and identification of hernias, recurrence rates, operative times, complication rates, postoperative pain, and cosmesis. The laparoscopic repair presents a viable alternative to open repair and offers a number of benefits over the traditional approach. These include superior visualization of the relevant anatomy, ability to assess and repair a contralateral hernia, lower rates of metachronous hernia, shorter operative times in bilateral hernia, and the potential for lower complication rates and improved cosmesis. This is accomplished without increasing recurrence rates or postoperative pain. Further research comparing the different approaches, including standardization of techniques and large randomized controlled trials, will be needed to definitively determine which is superior.

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: 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

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.

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.

We aimed to explore the feasibility and the safety of the laparoscopic surgery for incarcerated indirect inguinal hernia (IIH) in children. From January 2012 to December 2014, 64 children were enrolled into this study. All 64 patients received laparoscopic surgery and we reviewed their perioperative and postoperative follow-up studies. In addition, we enrolled 60 cases of children who received traditional surgery of IIH administered through minimally invasive surgery as the control group. Results from the present study showed that the mean operation time for the laparoscopic group was 41.5 min (range, 15–80 min) which was significantly shorter than the control group. Nine cases developed incarcerated intestine necrosis, expanded umbilical incision and parallel resection anastomosis. They received laparoscopic hernia sac high ligation. Only 5 cases developed scrotum edema after the surgery. The postoperative length of the stay ranged from 2 to 7 days (average, 3.2). The postoperative follow-up was from 6 months to 1 year and no relapse or secondary testicular atrophy was observed in the laparoscopic group. The operation time, incidence of postoperative complications and length of stay in the laparoscopic group were decreased compared to the control group, and differences were statistically significant (P<0.05). In conclusion, laparoscopic surgery treatment for incarcerated inguinal hernia is safe and feasible and produced better results compared with the alternative. PMID:28105089

A new method of treatment of postoperative ventral hernias was developed. During surgery under control over intraabdominal pressure hernial defect is closed with special devices for closure of wound margins. Plastic repair with local tissues in the form of duplication with uninterruptedly-recurrent suture (1st variant) or by contact method ("in join") with auto- or alloplasty on suture line (2nd variant) are performed when intraabdominal pressure doesn't change. If intraabdominal pressure increases, closure of the wound is stopped and polypropylene net or autodermal transplant (3rd variant) are sutured to margins of the wound. One hundred and sixty-eight patients with postoperative ventral hernias underwent surgeries with this method. Control group consisted of 110 patients. Recurrence of hernia was seen in 33 (30%) patients. There were no recurrences in the study group after the 2nd and 3rd variant of the surgery. In the 1st variant recurrence was seen in 6% cases. The method is recommended for surgical departments. Device immobilization permits to decrease tension in sutured tissue, creates optimal conditions for wound closure and prevents suture insufficiency.

Abdominal wall hernias are increasingly treated by laparoscopic placement of an intraperitoneal onlay mesh (IPOM). We present an alternative technique for women: the laparoscopic-assisted transvaginal IPOM. Before surgery, all patients underwent a gynecological examination. The patients agreed to IPOM repair via a transvaginal approach, and written informed consent for surgery was obtained. Pneumoperitoneum was established with a Veress needle at the umbilicus. This access was subsequently dilated to 5 mm (VersaStep), and a 5-mm laparoscope was inserted. Under laparoscopic view, the transvaginal trocars (12-mm VersaStep and 5-mm flexible accesses) were safely inserted after lifting the uterus with a uterus manipulator. After preparation of the falciform ligament, the ligamentum teres and the preperitoneal fat, a lightweight composite mesh was introduced through the transvaginal access and fixed with absorbable tacks using the double-crown technique. From September 2011 to December 2012, we performed six laparoscopic-assisted transvaginal IPOM procedures (one epigastric, three umbilical, two combined epigastric and umbilical hernias; all were primary hernias). In the initial phase, only patients with small or medium primary abdominal wall hernia were selected (max. 3 cm diameter). Median hospital stay was 3 days (range 2-6 days). One minor complication occurred perioperatively (second-degree skin burn to the labia majora). At 1-year follow-up, we identified one recurrence in a high-risk patient with a body mass index higher than 35 kg/m(2). No infection and no mortality were observed. Although no final conclusion can be made regarding the presumed non-inferiority of this technique in terms of recurrence and mesh infection compared with traditional laparoscopic IPOM, laparoscopic-assisted transvaginal IPOM is a feasible alternative to treat abdominal wall hernias.

Background: Ventral incisional hernias still remain a common surgical problem. We tested the feasibility of transvaginal placement of a large synthetic mesh to repair a porcine hernia. Methods: Seven pigs were used in this survival model. Each animal had creation of a 5-cm hernia defect and underwent a transvaginal repair of the defect with synthetic mesh. A single colpotomy was made using a 12-cm trocar for an overtube. The mesh was cut to size and placed through the trocar. A single-channel gastroscope with an endoscopic atraumatic grasper was used for grasping sutures. Further fascial sutures were placed every 5cm. Results: Mesh repair was feasible in all 7 animals. Mean operative time was 133 minutes. Technical difficulties were encountered. No gross contamination was seen at the time of necropsy. However, 5 animals had positive mesh cultures; 7 had positive cultures in the rectouterine space in enrichment broth or on direct culture. Conclusion: Transvaginal placement of synthetic mesh to repair a large porcine hernia using NOTES is challenging but feasible. Future studies need to be conducted to develop better techniques and determine the significance of mesh contamination. PMID:20932375

A systematic review of literature led us to take note that little was known about the costs of incisional ventral hernia repair (IVHR). Therefore we wanted to assess the actual costs of IVHR. The total costs are the sum of direct (hospital costs) and indirect (sick leave) costs. The direct costs were retrieved from a multi-centric cost analysis done among a large panel of 51 French public hospitals, involving 3239 IVHR. One hundred and thirty-two unitary expenditure items were thoroughly evaluated by the accountants of a specialized public agency (ATIH) dedicated to investigate the costs of the French Health Care system. The indirect costs (costs of the post-operative inability to work and loss of profit due to the disruption in the ongoing work) were estimated from the data the Hernia Club registry, involving 790 patients, and over a large panel of different Collective Agreements. The mean total cost for an IVHR in France in 2011 was estimated to be 6451€, ranging from 4731€ for unemployed patients to 10,107€ for employed patients whose indirect costs (5376€) were slightly higher than the direct costs. Reducing the incidence of incisional hernia after abdominal surgery with 5 % for instance by implementation of the European Hernia Society Guidelines on closure of abdominal wall incisions, or maybe even by use of prophylactic mesh augmentation in high risk patients could result in a national cost savings of 4 million Euros.

Laparoscopic hernioplasty was performed by either transabdominal preperitoneal or totally extraperitoneal approaches, The purpose of this study was to demonstrate that laparoscopic hernioplasty is a way to treat military personnel in the army with less pain and for the patients to return to an active lifestyle in a short time. A total of 217 laparoscopic hernioplasty were performed in 192 patients. Eighty-eight hernias were operated by transabdominal preperitoneal and the 146 hernias were operated by totally extraperitoneal approach hernioplasty. The mean +/- SD operation times were 69.4 +/- 23.94 and 58.3 +/- 24.13 minutes for the transabdominal preperitoneal and the totally extraperitoneal approach, respectively (p = 0.42). Postoperative pain was monitored by the visual analog scale. Hospitalization time for patients without complications was significantly shorter (p = 0.02). Laparoscopic hernioplasty could be performed on military personnel who need to return to work quickly with a short hospitalization time, less pain, and lower recurrence rate.
Two-stage laparoscopic treatment for strangulated inguinal, femoral and obturator hernias: totally extraperitoneal repair followed by intestinal resection assisted by intraperitoneal laparoscopic exploration.
Sasaki, A; Takeuchi, Y; Izumi, K; Morimoto, A; Inomata, M; Kitano, S
Total extraperitoneal preperitoneal (TEP) repair is widely used for inguinal, femoral, or obturator hernia treatment. However, mesh repair is not often used for strangulated hernia treatment if intestinal resection is required because of the risk of postoperative mesh infection. Complete mesh repair is required for hernia treatment to prevent postoperative recurrence, particularly in patients with femoral or obturator hernia. We treated four patients with inguinocrural and obturator hernias (a 72-year-old male with a right indirect inguinal hernia; an 83-year-old female with a right obturator hernia; and 86- and 82-year-old females with femoral hernias) via a two-stage laparoscopic surgery. All patients were diagnosed with intestinal obstruction due to strangulated hernia. First, the incarcerated small intestine was released and then laparoscopically resected. Further, 8-24 days after the first surgery, bilateral TEP repairs were performed in all patients; the postoperative course was uneventful in all patients, and they were discharged 5-10 days after TEP repair. At present, no hernia recurrence has been reported in any patient. The two-stage laparoscopic treatment is safe for treatment of strangulated inguinal, femoral, and obturator hernias, and complete mesh repair via the TEP method can be performed in elderly patients to minimize the occurrence of mesh infection.

The Rives-Stoppa (RS) repair of ventral incisional hernias (VIHR) is technically difficult. It involves the retromuscular placement of mesh anterior to the posterior fascia and the primary closure of the anterior fascia. Recurrence rates are 0-8%. We proposed that the operation could be done with equal success by placing the mesh in an intraperitoneal position and primarily closing the fascia anterior to the mesh. 81 patients who had undergone an open RS-VIHR with intraperitoneal mesh were evaluated for hernia recurrence and factors associated with recurrence. 55 women and 26 men (mean BMI 38+/-9) underwent RS-VIHR (mean age 49+/-11 years). Of these patients, 44 (54%) had a prior VIHR, 30 (37%) had an incarcerated hernia and 34 (42%) had multiple fascial defects. PTFE was used in 83% and Prolene in 12%. Average LOS was 5.8+/-12 days. All received perioperative intravenous antibiotics and 28% were discharged on oral antibiotics. Follow-up averaged 30+/-24 months. Recurrent VIH developed in 12/81 (15%), with three occurring after removal of infected mesh and one after a laparotomy. Excluding these four, the recurrence rate was 10%. There was no correlation between hernia recurrence and age, BMI, hernia size, number of prior repairs, or LOS (t-test p>0.05). Hernia recurrence did not correlate with gender, prior peritoneal contamination, incarceration, multiple defects, adhesions, mesh type, oral antibiotics, cardiac disease, diabetes, tobacco use, or seroma (X(2) p>0.05). Those with a wound infection and/or abscess formation had a significantly higher recurrent hernia rate (60% vs. 8%, X(2) p<0.001). Patients with pulmonary disease had a significantly higher recurrence rate (50% vs. 12%, X(2) p=0.01). RS-VIHR with intraperitoneal mesh is a successful and less technically challenging method of repair than prior modifications. Aggressive efforts to identify infection and treat early may prevent abscess formation and subsequent recurrent hernia. Patients with chronic

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

Traditional methods of clinical research may not be adequate to improve the value of care for patients with complex medical problems such as chronic pain after inguinal hernia repair. This problem is very complex with many potential factors contributing to the development of this complication. We have implemented a clinical quality improvement (CQI) effort in an attempt to better measure and improve outcomes for patients suffering with chronic groin pain (inguinodynia) after inguinal hernia repair. Between April 2011 and June 2016, there were 93 patients who underwent 94 operations in an attempt to relieve pain (1 patient had two separate unilateral procedures). Patients who had prior laparoscopic inguinal hernia repair (26) had their procedure completed laparoscopically. Patients who had open inguinal hernia repair (68) had a combination of a laparoscopic and open procedure in an attempt to relieve pain. Initiatives to attempt to improve measurement and outcomes during this period included the administration of pre-operative bilateral transversus abdominis plane and intra-operative inguinal nerve blocks using long-acting local anesthetic as a part of a multimodal regimen, the introduction of a low pressure pneumoperitoneum system, and the expansion of a pre-operative questionnaire to assess emotional health pre-operatively. The results included the assessment of how much improvement was achieved after recovery from the operation. Forty-five patients (48%) reported significant improvement, 39 patients (41%) reported moderate improvement, and 10 patients (11%) reported little or no improvement. There were 3 (3%) complications, 13 (11%) hernia recurrences, and 15 patients (13%) developed a new pain in the inguinal region after the initial pain had resolved. The principles of CQI can be applied to a group of patients suffering from chronic pain after inguinal hernia repair. Based on these results additional process improvement ideas will be implemented in an attempt

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.

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.

This study aims to evaluate the outcomes and utilization of porcine acellular dermal collagen implant (PADCI) during VHR at a large tertiary referral center. Records of 5485 patients who underwent VIHR from June 1995 to August 2014 were retrospectively reviewed to identify patients >18 years of age who had VIHR with PADCI reinforcement. Use of multiple mesh reinforcement products, inguinal hernias, and hiatal hernias were exclusion criteria. The primary outcome was hernia recurrence, and secondary outcomes were early complications and surgical site occurrences (SSOs). Uni- and multivariate analyses assessed risk factors for recurrence after PADCI reinforced VIHR. There were 361 patients identified (54.5% female, mean age of 56.7 ± 12.5 years, and mean body mass index (BMI) of 33.0 ± 9.9 kg/m(2)). Hypertension (49.5%), diabetes (24.3%), and coronary artery disease (14.4%) were the most common comorbidities, as was active smoking (20.7%). Most were classified as American Association of Anesthesiologists (ASA) Class 3 (61.7%). Hernias were distributed across all grades of the ventral hernia working group (VHWG) grading system: grade I 93 (25.7%), grade II 51 (14.1%), grade III 113 (31.3%), and grade IV 6 (1.6%). Most VIHR were performed from an open approach (96.1%), and were frequently combined with concomitant surgical procedures (47.9%). Early postoperative complications (first 30 days) were reported in 39.0%, with 71 being SSO. Of the 19.7% of patients with SSO, there were 31 who required procedural intervention. After a mean follow-up of 71.5 ± 20.5 months, hernia recurrence was documented in 34.9% of patients. Age and male gender were predictors of recurrence on multivariate analysis. To the best of our knowledge, this is the largest retrospective single institutional study evaluating PADCI to date. Hernias repaired with PADCI were frequently in patients undergoing concomitant operations. Reinforcement with PADCI may be considered a temporary

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.

Objective: To compare tension-free open mesh hernioplasty under local anaesthetic with transabdominal preperitoneal laparoscopic hernia repair under general anaesthetic. Design: A randomised controlled trial of 403 patients with inguinal hernias. Setting: Two acute general hospitals in London between May 1995 and December 1996. Subjects: 400 patients with a diagnosis of groin hernia, 200 in each group. Main outcome measures: Time until discharge, postoperative pain, and complications; patients’ perceived health (SF-36), duration of convalescence, and patients’ satisfaction with surgery; and health service costs. Results: More patients in the open group (96%) than in the laparoscopic group (89%) were discharged on the same day as the operation (χ2=6.7; 1 df; P=0.01). Although pain scores were lower in the open group while the effect of the local anaesthetic persisted (proportional odds ratio at 2 hours 3.5 (2.3 to 5.1)), scores after open repair were significantly higher for each day of the first week (0.5 (0.3 to 0.7) on day 7) and during the second week (0.7 (0.5 to 0.9)). At 1 month there was a greater improvement (or less deterioration) in mean SF-36 scores over baseline in the laparoscopic group compared with the open group on seven of eight dimensions, reaching significance on five. For every activity considered the median time until return to normal was significantly shorter for the laparoscopic group. Patients randomised to laparoscopic repair were more satisfied with surgery at 1 month and 3 months after surgery. The mean cost per patient of laparoscopic repair was £335 (95% confidence interval £228 to £441) more than the cost of open repair. Conclusion: This study confirms that laparoscopic hernia repair has considerable short term clinical advantages after discharge compared with open mesh hernioplasty, although it was more expensive. Key messages In the 4 hours after surgery laparoscopic hernia repair with general anaesthesia causes more pain

To compare institutional costs for open versus laparoscopic inguinal hernia repair and its relationship to reimbursement in an ambulatory surgery center in the United States. Analysis of institutional costs in US$ of 2006 for all nonreusables used in a laparoscopic total extraperitoneal (TEP) hernia repair using a polyester mesh compared with open hernia repair using polypropylene mesh. A comparison of the institution's disposable costs related to reimbursement at an ambulatory surgery center in Southeastern United States was performed to identify the most cost-effective procedure for the outpatient facility. As fixed and indirect costs of the ambulatory surgery center are similar for both procedures, a cost difference can only be found in direct disposable costs with that being US$ 235.57 for the procedure-specific disposables in the laparoscopic hernia repair as compared with US$ 117.15 for the open hernia repair. Cost for identical disposables used in both procedures amounted to US$ 32.57. Laparoscopic TEP hernia repair has a higher cost for procedure related disposables versus the open hernia repair at +US$ 118.42 mainly being due to the more costly polyester mesh. A flat rate reimbursement of US$ 1800 for a laparoscopic procedure compared with only US$ 950 for the open procedure minus all disposable cost results in a higher institutional income of +US&$ 731.58 (US$ 1531.86 vs. US$ 800.28), from which other institutional costs can be paid. Despite marginally higher procedure-related disposable costs for laparoscopic TEP hernia repair, the institutional income is remarkably higher owing to a better reimbursement for this procedure in ambulatory surgery centers. From the institution's point of view, laparoscopic hernia repair is by far the more cost-effective procedure when compared with an open hernia procedure at the present time.

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.

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.

Compared with open surgery, laparoscopic groin hernia repair has been shown to significantly reduce postoperative pain. However, chronic pain remains a problem with the laparoscopic approach, affecting approximately 10% of patients. The purpose of this study was to evaluate clinical outcomes following the use of Parietex ProGrip™ (Covidien, Dublin, Ireland) self-gripping mesh during laparoscopic totally extraperitoneal groin hernia repair. Data were collected prospectively from 145 male and 15 female patients with 235 inguinal hernias. All patients underwent repair by the laparoscopic totally extraperitoneal approach using Parietex ProGrip mesh. During follow-up ranging from 5 to 24 months, complications, pain score, patient satisfaction, and recurrence were analyzed. All patients were discharged on the day of surgery or the next morning. There were no immediate complications or returns to the operating room. Delayed postoperative complications included minor bruising to the genital region (3 cases), hematoma/seroma (1 case), and wound infection (1 case). The mean follow-up was 15 months, at which time there were no reports of hernia recurrence and 99% of patients were satisfied with their hernia repair. One patient (0.63%) reported severe pain (numeric rating scale score of >7), and 4 patients (2.5%) reported intermittent mild pain on exertion. The results of this study suggest that the use of a self-gripping mesh during the laparoscopic totally extraperitoneal approach is a promising and effective technique for repairing both primary and recurrent inguinal hernias.

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

Purpose We used an evidence-based approach to determine if the promotions and claims of superiority of biologic mesh over synthetic mesh use in ventral hernia repairs (VHRs) under contaminated conditions were sound and valid. Methods We searched the Medline database to specifically identify review articles relating to biologic mesh and VHR and critically reviewed these studies using an evidence-based approach. Results For the past forty-five years, four clinical reviews and one systematic review have included biologic meshes as part of a larger discussion on available prosthetics for VHR. All reviews supported biologic mesh use, especially in the setting of contaminated fields. Yet the primary literature included in these reviews and served as the basis for these conclusions consisted entirely of case series and case reports, which have the lowest level of evidence in determining scientific validity. Furthermore the FDA has neither cleared nor approved this particular use. Conclusions The cumulative data regarding biologic mesh use in VHRs under contaminated conditions does not support the claim that it is better than synthetic mesh used under the same conditions. The highly promoted and at least moderately utilized practice of placing biologic mesh in contamination is being done outside of the original intended use, and a re-evaluation of or possible moratorium on biologic mesh use in hernia surgery is seriously warranted. Alternatively, an industry-sponsored national registry of patients in whom ventral hernia repairs involved biologic mesh would substantively add to our understanding regarding how these intriguing biomaterials are being used and their overall clinical efficacy.

Institutions are now incentivized to decrease rates of preventable readmissions. The purpose of this study was to examine readmissions following open ventral hernia repair (VHR), to ultimately create a model to preoperatively identify high-risk patients. Utilizing the 2011 and 2012 ACS-NSQIP datasets, patients undergoing open VHR were identified by CPT codes. Patients who were readmitted in 2011 within 30 days of the procedure were compared to those who were not with regard to preoperative and operative characteristics. A bootstrap analysis was performed to identify internally validated risk factors to be included in the final logistic regression, which was utilized to create a weighted model to predict the risk of readmission. This model was then validated with VHR patients in 2012. Overall, 10,745 patients were included for model generation. Of these, 850 (7.9%) patients were readmitted within 30 days. The final bootstrap analysis demonstrated that active smoking, ASA ≥ 3, a history of bleeding disorder or anemia, long operative time, inpatient status, and concurrent panniculectomy were all independently associated with readmission following ventral hernia repair. Significant variables were assigned a weighted score, ranging from 1 to 3. Each patient was then placed into one of four cohorts according to their summed score. The internally validated model [Hernia Readmission Risk (HERR) Score] demonstrated that risk increased in a linear fashion, with the highest risk cohort having a 21% risk of 30-day readmission. Perioperative predictors of readmission following VHR include smoking, ASA score, operative magnitude, concurrent panniculectomy, and preoperative anemia and bleeding disorders. The presented model based on these factors can aid in perioperative risk stratification for readmission.

Inadequate peritoneal dissection from retroperitoneal structures may account for a large number of hernia recurrences amongst surgeons and trainees who are new to totally extraperitoneal (TEP) laparoscopic inguinal hernia repair. In this paper, we describe a simple dynamic test that allows surgeons to better appreciate the peritoneal edge during the initial dissection phase of TEP inguinal hernia repair, allowing for more adequate dissection of the peritoneum from retroperitoneal structures before placement of mesh. Data from a single surgeon was collected on 113 consecutive patients who underwent laparoscopic TEP inguinal hernia repair at the Royal North Shore Hospital in Sydney. The data was retrospectively reviewed to determine the number of cases in which the suction test led to further peritoneal dissection prior to mesh placement. After balloon dissection of the pre-peritoneal space and initial dissection of peritoneum and sac from retroperitoneal structures, a laparoscopic suction device is used to aspirate the insufflated gas from the pre-peritoneal space to cause the peritoneum to bulge anteriorly, thus demonstrating the edge of the peritoneal reflection. Further dissection is performed if deemed necessary at this point, and the mesh is placed over the hernia defect. 136 TEP hernia repairs were performed in 113 patients. In 26 (23 %) of patients, the abovementioned technique was of particular value resulting in further dissection of peritoneum prior to mesh placement. There were no complications as a direct result of the test. This dynamic suction test is a risk-free and useful operative tool for surgeons and trainees who are new to TEP inguinal hernia repair, and provides a definitive way of identifying the peritoneal reflection to ensure the peritoneum has been dissected adequately prior to mesh placement.

The use of point-of-care ultrasound for the diagnosis of bowel obstructions and hernias is becoming increasingly common in the emergency department (ED). Using a relatively rare case of an incisional port hernia, we demonstrate the ultrasound findings of a strangulated hernia causing a partial small bowel obstruction. A 46-year-old female presented four days following a laparoscopic surgery complaining of abdominal pain, nausea and lack of bowel movements. There was a palpable mass in the left lower quadrant under the 12mm trocar port incision. ED point-of-care ultrasound revealed herniated akinetic loops of bowel through her laparoscopy incision. This is the first case report to describe the use of point-of-care ultrasound for the diagnosis of a strangulated incisional port hernia at the bedside. PMID:25987928

Introduction: Laparoscopic parastomal hernia repair with modified Sugarbaker technique has become increasingly the operation of choice because of its low recurrence rates. This study aimed to assess feasibility, safety, and efficiency of performing the same operation with single-incision laparoscopic surgery. Materials and Methods: All patients referred from March 2010 to February 2013 were considered for single-port laparoscopic repair with modified Sugarbaker technique. A SILS port (Covidien, Norwalk, Connecticut, USA) was used together with conventional straight dissecting instruments and a 5.5- mm/52-cm/30° laparoscope. Important technical aspects include modified dissection techniques, namely, “inline” and “chopsticks” to overcome loss of triangulation, insertion of a urinary catheter into an ostomy for ostomy limb identification, safe adhesiolysis by avoiding electocautery, saline -jet dissection to demarcate tissue planes, dissection of an entire laparotomy scar to expose incidental incisional hernias, adequate mobilization of an ostomy limb for lateralization, and wide overlapping of defect with antiadhesive mesh. Results: Of 6 patients, 5 underwent single-port laparoscopic repair, and 1 (whose body mass index [BMI] of 39.4 kg/m2 did not permit SILS port placement) underwent multiport repair. Mean defect size was 10 cm, and mean mesh size was 660 cm2 with 4 patients having incidental incisional hernias repaired by the same mesh. Mean operation time was 270 minutes, and mean hospital stay was 4 days. Appliance malfunction ceased immediately, and pain associated with parastomal hernia disappeared. There was no recurrence with a follow-up of 2 to 36 months. Conclusion: Compared with multiport repair, single-port laparoscopic parastomal repair with modified Sugarbaker technique is safe and efficient, and it may eventually become the standard of care.

Mesh placement during repair of acutely incarcerated ventral and groin hernias is associated with high rates of surgical site infection (SSI). The utility of preoperative computed tomography (CT) in this setting is unclear. We hypothesized that CT evidence of bowel wall compromise would predict SSI while accounting for physiologic parameters. We performed a 4-year retrospective cohort analysis of 50 consecutive patients who underwent mesh repair of acutely incarcerated ventral or groin hernias. We analyzed chronic disease burden, acute illness severity, CT findings, operative management, and herniorrhaphy-specific outcomes within 180 days. The primary outcome was SSI by the Centers for Disease Control and Prevention criteria. Multiple logistic regression was performed to identify independent predictors of SSI. Eighty-four percent of all patients were American Society of Anesthesiologists class III or IV, 28% were active smokers, and mean body mass index (BMI) was 35 kg/m. Fifty-four percent had ventral hernias, 40% had inguinal hernias, and 6% had femoral or combined inguinal/ femoral hernias. Seventy percent of preoperative CT scans had features suggesting bowel compromise, abdominal free fluid, or fluid in the hernia sac. Surgical site infection occurred in 32% of all patients (8% superficial, 24% deep or organ/space). The strongest predictors of SSI were CT evidence of fluid in the hernia sac (odds ratio [OR], 8.3; 95% confidence interval [CI], 1.7-41), initial heart rate 90 beats/min or greater (OR, 6.3; 95% CI, 1.1-34), and BMI 35 kg/m or greater (OR, 5.8; 95% CI, 1.2-28). Surgical site infection rates were significantly higher among patients who had CT evidence of fluid in the hernia sac (56% vs. 19%, p = 0.012). More than half of all patients with CT scan evidence of fluid in the hernia sac developed an SSI. Computed tomography evidence of fluid in the hernia sac was the strongest predictor of SSI, followed by heart rate and BMI. Together, these parameters

The incidence of incisional hernia after laparoscopic surgery is reportedly 0-5.2 %; there are only a few reports of that following retroperitoneal laparoscopic nephrectomy. We evaluated the incidence of and risk factors for incisional hernia after retroperitoneal laparoscopic nephrectomy, and the efficacy of our novel prophylaxis technique. A total of 207 renal cell carcinoma patients who underwent laparoscopic nephrectomy at Chiba University Hospital were retrospectively enrolled in this study. We compared the incidences of incisional hernia following the transperitoneal vs. retroperitoneal approaches, and, among the latter group, the incidences with vs. without use of our prophylaxis method. Also among the retroperitoneal-approach group, we evaluated selected patient characteristics as potential hernia risk factors. The rate of incisional hernias was 14 (8.7 %) after 161 retroperitoneal laparoscopic nephrectomies and one (2.2 %) after 46 transperitoneal laparoscopic nephrectomies (P = 0.132). For those undergoing the retroperitoneal approach, 14 (11.3 %) hernias were identified in 124 non-prophylaxed patients and none in 37 prophylaxed patients. Transversus abdominis fascia closure was a statistically significant factor for reducing the incidence of incisional hernia after retroperitoneal laparoscopic nephrectomy (P = 0.0324): rectus abdominis muscle thickness ≤7 mm and perioperative blood loss >100 ml were statistically significant independent risk factors, by multivariate analysis. To prevent incisional hernia after retroperitoneal laparoscopic nephrectomy in the patients with risk factors, it is useful to close the transversus abdominis fascia at the port sites from inside the surgical cavity, through the open specimen-removal trocar port site, under direct observation.

Internal hernia of the small bowel through a mesenteric defect following colorectal cancer surgery is a serious but rarely reported complication. The aim of this study was to evaluate the incidence, clinical features, and management of these hernias. We retrospectively reviewed 4589 primary colorectal cancer patients who underwent surgical resection between January 2007 and December 2015. The incidence, clinical presentations, and short-term outcomes of patients with symptomatic internal hernia following colorectal surgery were investigated in detail. We found 9 (0.2 %) patients who presented with symptomatic internal hernia. In all cases, preceding surgical procedures were laparoscopic anterior resection (n = 9), including low anterior resection (n = 3) and intersphincteric resection (n = 3). The median time interval between initial surgery and the occurrence of internal hernia was 4 months (range 5 days-27 months). Main symptoms were abdominal distension and pain; 4 (44.4 %) patients presented with systemic inflammatory response syndrome. Most cases (7/9, 77.8 %) were suspected of internal hernia by preoperative abdominal computed tomography. Six (66.6 %) patients underwent emergency surgery, after which all developed postoperative complications without mortality. The median hospital stay was 27.5 days (range 25-54 days) among patients who underwent surgical intervention. Internal hernia following colorectal cancer surgery is a rare but potentially fatal complication, and as such, early recognition and management of these cases are important.

Internal hernia is a rare cause of bowel obstruction which often requires emergent surgery. In general, the preoperative diagnosis of internal hernia is difficult. The pelvic cavity has various spaces with the potential to result in a hernia, especially in females. In this report, we describe a patient with an internal hernia secondary to previous gynecologic surgery. A 49-year-old woman presented with acute abdominal pain and a history of previous right oophorectomy for a benign ovarian cyst. Computed tomography scan of the abdomen showed obstruction with strangulation and emergent laparoscopic exploration was performed. Intraoperatively, there was an incarcerated internal hernia in the pelvis, located in the vesicouterine pouch, which was reduced. The orifice of the hernia was a 2 cm defect caused by adhesions between the uterus and bladder. The defect was closed with a continuous suture. The herniated bowel was viable, and the operation was completed without intestinal resection. She was discharged four days after surgery without complications. Laparoscopy is useful to diagnose bowel obstruction in selected patients and may also be used for definitive therapy. It is important to understand pelvic anatomy and consider an internal hernia of the pelvic cavity in females, in the differential diagnosis of bowel obstruction, especially those with a history of gynecological surgery.

The choice of approach to the laparoscopic repair of inguinal hernia is controversial. There is a scarcity of data comparing the laparoscopic transabdominal preperitoneal (TAPP) approach with the laparoscopic totally extraperitoneal (TEP) approach and questions remain about their relative merits and risks. To compare the clinical effectiveness and relative efficiency of laparoscopic TAPP and laparoscopic TEP for inguinal hernia repair. We searched Medline Extra, Embase, Biosis, Science Citation Index, Cochrane Central Register of Controlled Trials (CENTRAL), Journals@ Ovid Full Text and the electronic version of the journal, Surgical Endoscopy. Recent conference proceedings by the following organisations were hand searched: Association of Endoscopic Surgeons of Great Britain & Ireland; International Congress of the European Association for Endoscopic Surgery; Scientific Session of the Society of American Gastrointestinal & Endoscopic Surgeons (SAGES); and the Italian Society of Endoscopic Surgery. In addition, specialists involved in research on the repair of inguinal hernia were contacted to ask for information about any further completed and ongoing trials, relevant websites were searched and reference lists of the all included studies were checked for additional reports. All published and unpublished randomised controlled trials and quasi-randomised controlled trials comparing laparoscopic TAPP with laparoscopic TEP for inguinal hernia repair were eligible for inclusion. Non-randomised prospective studies were also eligible for inclusion to provide further comparative evidence of complications and adverse events. Statistical analyses were performed using the fixed effects model and the results expressed as relative risk (RR) for dichotomous outcomes and weighted mean difference (WMD) for continuous outcomes with 95% confidence intervals (CI). The search identified one RCT which reported no statistical difference between TAPP and TEP when considering duration of

Iatrogenic diaphragmatic hernia following laparoscopic left colectomy for splenic flexure cancer. An unusual complication Diaphragmatic hernias are a migration of abdominal structures into the thorax via a diaphragmatic defect; they may be classified as congenital or acquired and acquired hernias can be hiatal, traumatic or iatrogenic, generally complications of thoracic or abdominal surgery. We report a case of iatrogenic diaphragmatic hernia after a laparoscopic left colectomy for splenic flexure tumor; to our knowledge, in literature this case is the first reported. A 51-years-old woman was readmitted to our Hospital on 11th post-operative day for bowel occlusion and a CT - scan revealed left diaphragmatic herniation with fluid dilatation of the small bowel that appeared in the left hemithorax. Laparoscopic surgery resolution was decided and after the reduction of the small bowel in the abdomen we closed the defect using two direct absorbable auto-block hemi-continuous sutures that were covered by a synthetic absorbable mesh. Probably we didn't notice a minimal injury of the left diaphragm caused by ultrasonic scalpel and we can suppose that this delay in presentation may be a result of the gradual enlargement of a microscopic lesion. Patient's gas exchanges were good during surgery and during post-operative course.

Recently introduced slow-resorbing biosynthetic and non-resorbing macroporous polypropylene meshes are being used in hernias with clean-contaminated and contaminated wounds. However, information about the use of biosynthetic meshes and their outcomes compared with polypropylene meshes in clean-contaminated and contaminated cases is lacking. Here we evaluate the use of biosynthetic mesh and polypropylene mesh in elective open ventral hernia repair (OVHR) and investigate differences in early wound morbidity after OVHR within clean-contaminated and contaminated cases. All elective, OVHR with biosynthetic mesh or uncoated polypropylene mesh from January 2013 through October 2016 were identified within the Americas Hernia Society Quality Collaborative. Association of mesh type with 30-day wound events in clean-contaminated or contaminated wounds was investigated using a 1:3 propensity-matched analysis. Biosynthetic meshes were used in 8.5% (175 of 2,051) of elective OVHR, with the majority (57.1%) used in low-risk or comorbid clean cases. Propensity-matched analysis in clean-contaminated and contaminated cases showed no significant difference between biosynthetic mesh and polypropylene mesh groups for 30-day surgical site occurrences (20.7% vs 16.7%; p = 0.49) or unplanned readmission (13.8% vs 9.8%; p = 0.4). However, surgical site infections (22.4% vs 10.9%; p = 0.03), surgical site occurrences requiring procedural intervention (24.1% vs 13.2%; p = 0.049), and reoperation rates (13.8% vs 4.0%; p = 0.009) were significantly higher in the biosynthetic group. Biosynthetic mesh appears to have higher rates of 30-day wound morbidity compared with polypropylene mesh in elective OVHR with clean-contaminated or contaminated wounds. Additional post-market analysis is needed to provide evidence defining best mesh choices, location, and surgical technique for repairing contaminated ventral hernias.

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

INTRODUCTION: The repair of the recurrent hernia is a daunting task because of already weakened tissues and distorted anatomy. Open posterior preperitoneal approach gives results far superior to those of the anterior approach. Laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair is an evolving technique associated with advantages of a minimally invasive approach. The present work aimed at comparing these three approaches for repair of recurrent inguinal hernia regarding complications and early recurrence. MATERIALS AND METHODS: A total of 180 patients were divided randomly into three equal groups: A, B, and C. Group A patients were subjected to open posterior preperitoneal approach , those of group B were subjected to transinguinal anterior tension-free repair and group C patients were subjected to TAPP. The primary end point was recurrence and the secondary end points were time off from work, postoperative pain, scrotal swelling, and wound infections. RESULTS: The mean hospital stay, the mean time to return to work and the mean time off from work were less in group C then A and B. Chronic postoperative pain was observed in eight patients in group A (13.33%), in 18 patients in group B (30%) and six patients in group C (10%). The overall complication rate was 19.7% in both groups A and C and 34.36% in group B. CONCLUSION: In recurrent inguinal hernia, the laparoscopic and open posterior approaches are equally effective in term of operative outcome. The open preperitoneal hernia repair is inexpensive, has a low recurrence rate. Postoperative recovery is short and postoperative pain is minimal. This approach gives results far superior to those of the commonly used anterior approach. However, while laparoscopic hernia repair requires a lengthy learning curve and is difficult to learn and perform, it has advantages of less post-operative pain, early recovery with minimal hospital stay, low post-operative complications and recurrence.

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.

We aimed to assess the efficacy of transversus abdominis plane (TAP) block and rectus sheath (RS) block in patients undergoing laparoscopic inguinal hernia surgery. Few studies have addressed the efficacy and safety associated with TAP block and RS block for laparoscopic surgery. Thirty-two patients underwent laparoscopic inguinal hernia surgery, either with TAP and RS block (Block+ group, n = 18) or without peripheral nerve block (Block− group, n = 14). Preoperatively, TAP and RS block were performed through ultrasound guidance. We evaluated postoperative pain control and patient outcomes. The mean postoperative hospital stays were 1.56 days (Block+ group) and 2.07 days (Block− group; range, 1–3 days in both groups; P = 0.0038). A total of 11 patients and 1 patient underwent day surgery in the Block+ and Block− groups, respectively (P = 0.0012). Good postoperative pain control was more commonly observed in the Block+ group than in the Block− group (P = 0.011). TAP and RS block was effective in reducing postoperative pain and was associated with a fast recovery in patients undergoing laparoscopic inguinal hernia surgery. PMID:25875548

This review reports the incidence of mesh-related erosion after ventral mesh rectopexy to determine whether any difference exists in the erosion rate between synthetic and biological mesh. A systematic search of the MEDLINE and the Ovid databases was conducted to identify suitable articles published between 2004 and 2015. The search strategy capture terms were laparoscopic ventral mesh rectopexy, laparoscopic anterior rectopexy, robotic ventral rectopexy, and robotic anterior rectopexy. Eight studies (3,956 patients) were included in this review. Of those patients, 3,517 patients underwent laparoscopic ventral rectopexy (LVR) using synthetic mesh and 439 using biological mesh. Sixty-six erosions were observed with synthetic mesh (26 rectal, 32 vaginal, 8 recto-vaginal fistulae) and one (perineal erosion) with biological mesh. The synthetic and the biological mesh-related erosion rates were 1.87% and 0.22%, respectively. The time between rectopexy and diagnosis of mesh erosion ranged from 1.7 to 124 months. No mesh-related mortalities were reported. The incidence of mesh-related erosion after LVR is low and is more common after the placement of synthetic mesh. The use of biological mesh for LVR seems to be a safer option; however, large, multicenter, randomized, control trials with long follow-ups are required if a definitive answer is to be obtained.

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

We herein present a case in which we used a totally laparoscopic approach for early gastric cancer accompanied by a huge hiatal hernia. An 80-year-old Japanese woman was referred with a chief complaint of dysphagia. A clinical diagnosis of early gastric cancer, T1b (SM) N0M0, stage IA, accompanied by hiatal hernia, was made. Distal gastrectomy with D1 plus lymphadenectomy was carried out. After the gastrectomy, the hernial sac was excised and the hernial orifice was closed. Reconstruction using the Roux-en-Y method was selected. The postoperative course was uneventful and she was discharged on postoperative day 10.

To determine the influence of intra-abdominal pressure (IAP) on respiratory function after surgical repair of ventral hernia and to compare two different methods of IAP measurement during the perioperative period. Thirty adult patients after elective repair of ventral hernia were enrolled into this prospective study. IAP monitoring was performed via both a balloon-tipped nasogastric probe [intragastric pressure (IGP), CiMON, Pulsion Medical Systems, Munich, Germany] and a urinary catheter [intrabladder pressure (IBP), UnoMeterAbdo-Pressure Kit, UnoMedical, Denmark] on five consecutive stages: (1) after tracheal intubation (AI); (2) after ventral hernia repair; (3) at the end of surgery; (4) during spontaneous breathing trial through the endotracheal tube; and (5) at 1 h after tracheal extubation. The patients were in the complete supine position during all study stages. The IAP (measured via both techniques) increased on average by 12% during surgery compared to AI (P < 0.02) and by 43% during spontaneous breathing through the endotracheal tube (P < 0.01). In parallel, the gradient between РаСО2 and EtCO2 [Р(а-et)CO2] rose significantly, reaching a maximum during the spontaneous breathing trial. The PаO2/FiO2 decreased by 30% one hour after tracheal extubation (P = 0.02). The dynamic compliance of respiratory system reduced intraoperatively by 15%-20% (P < 0.025). At all stages, we observed a significant correlation between IGP and IBP (r = 0.65-0.81, P < 0.01) with a mean bias varying from -0.19 mmHg (2SD 7.25 mmHg) to -1.06 mm Hg (2SD 8.04 mmHg) depending on the study stage. Taking all paired measurements together (n = 133), the median IGP was 8.0 (5.5-11.0) mmHg and the median IBP was 8.8 (5.8-13.1) mmHg. The overall r (2) value (n = 30) was 0.76 (P < 0.0001). Bland and Altman analysis showed an overall bias for the mean values per patient of 0.6 mmHg (2SD 4.2 mmHg) with percentage error of 45.6%. Looking at changes in IAP between the different study

The results of complex clinical and ultrasonic investigation of abdominal wall and following surgical treatment in 60 women with umbilical and postoperative large ventral hernias combined with abdomen ptosis were analyzed. Patients were divided into 2 groups with 30 people per group. Endoprosthetic replacement of abdominal wall defect using standard polypropylene prosthesis was applied in the 1st group, endoprosthetic replacement with musculoaponeurotic tissues lifting in hypogastric area using original super lightweight polypropylenepolyvinylidenefluoride prosthesis--in the 2nd group. Polypropylene endoprosthesisconsist of main flap 15×15 cm with roundish edges and additional flap 5×40 cm in the form of wide stripe placed at the lower edge of main flap transversely to its direction. It was revealed increased physical health component in 1.8 times, psychic--in 2.5 times in the 2nd group. Thus number of excellent results increased on 33.3% and amount of satisfactory outcomes reduced on 30%.

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.

Meckel's diverticulum is the most common congenital abnormality of the gastrointestinal tract and is the result of the incomplete obliteration of the omphalomesenteric duct. Herniation of Meckel's diverticulum is called Littre's hernia and is a rare occurrence. Herein is described an extremely rare case of incarcerated and strangulated Meckel's diverticulum through an incisional ventral defect in a 59-year-old female patient, who presented with manifestations of acute surgical abdomen. At emergency laparotomy, a strangulated small-bowel loop containing a Meckel's diverticulum was found, which had migrated through the subcutaneous tissues to the right iliac fossa, where a painful mass was palpated on admission. Segmental resection of the ischemic ileum was performed and the abdomen was closed without the use of a prosthetic mesh. Histopathological findings were suggestive of a true diverticulum containing heterotopic gastric mucosa.

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.

To date, little is known about the benefits of preoperative bowel preparation in patients undergoing elective ventral hernia repair (VHR). The purpose of this study was to determine the effect of preoperative bowel preparation on 30-day wound events in patients undergoing elective VHR using the Americas Hernia Society Quality Collaborative (AHSQC). All patients undergoing elective VHR from January 2013 through January 2016 were identified within the AHSQC. Patients undergoing emergency VHR and those with a CDC wound class IV were excluded from our analysis. Patients were divided into 2 groups: Clean (CDC wound class I) and Contaminated (CDC wound classes II and III). The association of preoperative bowel preparation with 30-day wound events was investigated using logistic regression modeling. A total of 3,709 patients met inclusion criteria; 3,101 (83.6%) had CDC wound class I, and 608 (16.4%) had CDC wound classes II or III. Within the Clean group, patients who underwent preoperative bowel preparation were significantly more likely to experience a surgical site infection (SSI), surgical site occurrence (SSO), and surgical site occurrence requiring procedural intervention (SSOPI). Within the Contaminated group, patients who underwent preoperative bowel preparation were significantly more likely to experience an SSOPI. The use of preoperative bowel preparation in patients undergoing elective VHR does not reduce the risk of 30-day wound events. Copyright © 2016 American College of Surgeons.

Introduction Incisional hernias are a common complication following abdominal surgery and they represent about 80% of all ventral hernia. In uncomplicated postoperative follow-up they can develop in about eleven percent of cases and up to 23% of cases with wound infections or other forms of wound complications. Localisation and size of the incisional hernia can vary according to the causal abdominal scar. Conservative treatment (e. g. weight reduction) is only available to relieve symptoms while operative treatments are the only therapeutic treatment option for incisional hernia. Traditionally, open suture repair was used for incisional hernia repair but was associated with recurrence rates as high as 46%. To strengthen the abdominal wall and prevent the development of recurrences the additional implantation of an alloplastic mesh is nowadays commonly used. Conventional hernia surgery as well as minimally invasive surgery, introduced in the early 90s, make use of this mesh-technique and thereby showed marked reductions in recurrence rates. However, there are possible side effects associated with mesh-implantation. Therefore recommendations remain uncertain on which technique to apply for incisional hernia repair and which technique might, under specific circumstances, be associated with advantages over others. Objectives The goal of this HTA-Report is to compare laparoscopic incisional hernia repair (LIHR) and conventional incisional hernia repair with and without mesh-implantation in terms of their medical efficacy and safety, their cost-effectiveness as well as their ethical, social und legal implications. In addition, this report aims to compare different techniques of mesh-implantation and mesh-fixation as well as to identify factors, in which certain techniques might be associated with advantages over others.

To conduct a meta-analysis of contralateral metachronous inguinal hernia (CMIH) that originated from negative laparoscopic evaluation for contralateral patent processus vaginalis (CPPV) in children who presented with a unilateral inguinal hernia and to determine the incidence of and factors associated with such a CMIH. A PubMed search was performed for all studies concerning laparoscopic repair or evaluation of inguinal hernia in children. The search strategy was as follows: (laparoscop* OR coelioscop* OR peritoneoscop* OR laparoendoscop* OR minilaparoscop*) AND ("inguinal hernia" OR "metachronous hernia") AND child*. Inclusion criteria included unilateral inguinal hernia in children, negative laparoscopic evaluation of CPPV, without history of contralateral inguinal surgery previously, and clearly reporting CMIH development or not. Editorials, letters, review articles, case reports, animal studies, and duplicate patient series were excluded. Twenty-three studies comprising 6091 children with negative CPPV fulfilled the inclusion criteria and were included in the final analysis, of whom 80 (1.31%) subsequently presented with a CMIH. Subgroup analysis showed that CMIH incidence was lower through an umbilical approach than via an inguinal one (0.85% versus 1.78%, P=.009). As for the transinguinal approach, there was a CMIH incidence of 0.78% and 2.05%, respectively, for laparoscopy with a small angle (30° and 70°), whereas there was no CMIH development for that with a large angle (110°, 120°, and flexible). A high pneumoperitoneum pressure (>10 mm Hg, >12 mm Hg, and >14 mm Hg) was usually associated with a slightly higher CMIH incidence than a low one (≤10 mm Hg, ≤12 mm Hg, and ≤14 mm Hg), all without significant difference. CMIH incidence was slightly lower for using a broad CPPV definition than for using a narrow one (0.64% versus 1.35%, P=.183). CMIH following negative laparoscopic evaluation for CPPV was a rare but possible phenomenon

Laparoscopic treatment of large hiatal hernias seems to be associated with a high recurrence rate that some authors suggest to bring down by performing prosthetic closure of the hiatus. However, prosthetic repair remains controversial owing to severe and still underestimated complications. The aims of this study were to assess the long-term functional and objective results of laparoscopic treatment without prosthetic patch, and to identify the risk factors of recurrence. From November 1992 to March 2009, 89 patients underwent laparoscopic treatment of a large hiatal hernia without prosthetic patch, involving excision of the hernial sac, cruroplasty, fundoplication, and often anterior gastropexy. The postoperative assessment consisted of a barium esophagram on day 2, an office visit at 2 months with a 24-h pH study, an esophageal manometry, and then a long-term prospective yearly follow-up with a barium esophagram at 2 years. Out of the 89 laparoscopic procedures, four required a conversion (4.4%). Seventy-seven patients underwent a Boerema's anterior gastropexy (86.5%). The morbidity rate was 7.8%, and the mortality rate was nil. Eleven patients (12.3%) were lost to follow-up. We had 91.5% of very good early functional results and 75.3% of good results after a mean follow-up of 57.5 months. Fourteen recurrences of hiatal hernias (15.7%) were identified, four of which (28.6%) occurred early after surgery. Three factors seemed significantly associated with recurrence: the absence of anterior gastropexy (p = 0.0028), the group of younger patients (p = 0.03), and a history of abdominal surgery (p = 0.01). Large hiatal hernias can be treated by laparoscopy without prosthetic patch with a satisfying long-term result. Performing anterior gastropexy seems to significantly reduce the recurrences.

Incisional hernias are one of the most frequent complications of open abdominal surgery. The incidence of relapses after a conventional repair procedure is higher in recurrent than in primary cases (30%-50% vs. 11%-20%). The laparoscopic approach can prevent the complications associated with the conventional approach when dealing with recurrent incisional hernias. The aim of this study was to evaluate the efficacy of laparoscopic treatment in such cases. We prospectively analyzed data from 41 consecutive patients with recurrent incisional hernias, who submitted to a laparoscopic repair procedure with an expanded polytetrafluoroethylene Dual Mesh (Gore-Tex Dual Mesh Plus Biomaterial; W.L. Gore 8 Associates) from December 2001 to December 2004. All of the patients underwent clinical follow-up at 1, 6, and 12 months and then yearly. An ultrasound scan of the abdominal wall was performed at 6 and 12 months after the procedure. The parameters considered for the analysis were: mesh size, operating time, hospital stay, postoperative complications, and recurrences. The defects were usually localized along midline laparotomies. The mean mesh size was 400 cm2, the mean operating time was 68 minutes, and the mean length of hospital stay was 2.7 days. Complications were encountered in 17% of patients. The mean follow-up was 38 months (range, 18-54). Recurrence was reported in 1 case only (2.4%), which occurred within the first 6 months after the operation. The laparoscopic repair of recurrent incisional hernia seems to be an effective alternative to the conventional approach, as it can give lower recurrence and complication rates.

A female northern elephant seal (Mirounga angustirostris) weaned pup presented with malnutrition. During rehabilitation, the seal developed regurgitation and reduced lung sounds on auscultation. Radiographs and endoscopy performed under sedation suggested a diaphragmatic hernia. A Type I (or sliding) hiatal hernia was confirmed with a positive contrast upper gastrointestinal study, revealing varying degrees of herniation of the gastric fundus through the diaphragm into the caudal thorax as well as esophageal reflux. The animal was treated preoperatively with an H2 antagonist and antinausea medication. A laparoscopic gastropexy was performed under general anesthesia. The animal recovered well postoperatively and resolution of clinical signs was achieved. The animal was released back into the wild 21 kg above admit weight. To our knowledge, we report here the first surgical correction of a hiatal hernia in a marine mammal.

The aim of this study was to describe a ventral laparoscopic technique for bilateral medial iliac lymphadenectomy in dogs. Twelve intact male purpose-bred research dogs weighting less than 15 kg were positioned in dorsal recumbency, and a 3-portal technique was used. Bilateral dissection was performed with vessel-sealing devices while tilting the surgical table by up to 30° towards the contralateral side of the target medial iliac lymph node (MILN) without changing the surgeon's position. Using a ventral laparoscopic approach, bilateral MILNs were identified and excised in all dogs. The mean time for unilateral and bilateral MILN dissections were 9.7 ± 3.8 min and 21.0 ± 6.0 min, respectively. The mean times for the right and left MILN dissections were 10.8 ± 4.3 min and 9.8 ± 2.5 min, respectively. The mean total surgery time was 43.7 ± 7.7 min. In total, 26 MILNs were dissected. Several complications, including, mild to moderate capillary hemorrhage from perinodal fat and vessels (controlled laparoscopically), mild spleen trauma caused by the first trocar insertion, and capsular damage of MILNs, were observed. However, there were no other major complications. All MILN samples were evaluated and deemed suitable for histopathologic diagnosis. Laparoscopic excision of MILNs is a useful method of excisional biopsy for histopathologic diagnosis. Using this ventral laparoscopic approach with the 3-portal technique, bilateral MILN dissection suitable for obtaining histopathologic samples could be achieved in a short time in dogs weighing less than 15 kg.

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.

This study aimed to compare laparoendoscopic single-site (LESS) total extraperitoneal (TEP) repair with conventional laparoscopic TEP repair for the treatment of inguinal hernias. To date, no other studies have compared the LESS and conventional laparoscopic TEP approaches for the treatment of inguinal hernia in a prospective randomized study setting. For this study, 100 patients undergoing inguinal hernia repair were prospectively randomized into either the LESS TEP group or the conventional laparoscopic TEP group. Pre-, intra-, and postoperative factors were recorded. The primary end point was postoperative pain. The patients were interviewed at outpatient clinics at 1 week, 3 months, and 6 months postoperatively. The demographic data were comparable between the two groups. The median operative time was longer in the LESS TEP group (63.5 min) than in the conventional TEP group (50.5 min) (p = 0.001). No conversion was performed in either group. The mean pain score 2 h postoperatively during rest was significantly higher in the conventional TEP group than in the LESS TEP group (3.9 vs. 2.6; p = 0.02). The postoperative results were comparable between the groups in terms of analgesic requirements, systemic stress responses, complications, and postoperative convalescence. The LESS TEP technique is associated with a longer operative time but offers the minor benefit of a reduction in immediate postoperative pain.

the role of simulation for training in procedures such as laparoscopic incisional hernia repair (LIHR) is unknown. The purpose of this study was to determine whether performance in simulated LIHR correlates with operating room (OR) performance. subjects performed LIHR in the University of Maryland Surgical Abdominal Wall (SAW) simulator and the OR. Trained observers used a LIHR-specific global rating scale (Global Operative Assessment of Laparoscopic Skills-Incisional Hernia) to assess performance. Global Operative Assessment of Laparoscopic Skills-Incisional Hernia includes 7 domains (trocar placement, adhesiolysis, mesh sizing, mesh positioning, mesh fixation, knowledge and autonomy in instrument use, and overall competence). The correlation between simulator and OR performance was assessed using the Pearson coefficient. fourteen surgeons from 2 surgical departments participated. Experienced surgeons (n = 9) were defined as attending surgeons and minimally invasive surgury (MIS) fellows, and novice surgeons (n = 5) were general surgery residents (postgraduate years 3-5). The correlation between performance in the OR and the simulator for the entire group was .87 (95% confidence interval, .63-.96; P < .001). there was an excellent correlation between LIHR performance in the simulator and clinical LIHR. This suggests that performance in the SAW simulator may predict performance in the operating room. 2011 Elsevier Inc. All rights reserved.

Objective To evaluate the influence of the laparoscopic technique in hernia repair regarding time to full recovery and return to work, complications, recurrence rate, and economic aspects. Summary Background Data Several studies have shown advantages in terms of less pain and faster recovery after laparoscopic hernia repair, whereas others have not, and the cost-effectiveness has been questioned. The laparoscopic technique must be thoroughly compared with the open procedures before its true place in hernia surgery can be defined. Methods Six hundred thirteen male patients aged 40 to 75 years were randomized to the conventional procedure, preperitoneal mesh placed by the open technique, or laparoscopic preperitoneal mesh (TAPP). Follow-up was after 7 days, 8 weeks, and 1 year. Results Of 613 patients undergoing surgery, 604 (98.5%) were followed for 1 year. Patients who underwent TAPP gained full recovery after 18.4 days, compared with 24.2 days for open mesh (p < 0.001) and 26.4 days for the conventional procedure (p < 0.001). Patients who underwent TAPP returned to work after 14.7 days, compared with 17.7 days for open mesh (p = 0.05) and 17.9 days for the conventional procedure (p = 0.04). They also had significantly less restriction in physical activities after 7 days. The TAPP procedure was more expensive, mainly as a result of longer surgical time and equipment costs, even after compensation for earlier return to work. Complications were more common in the TAPP group, with a varying pattern between the groups. Four recurrences in the conventional, 11 in the open mesh, and 4 in the TAPP group were recorded after 1 year (p = n.s.). Conclusion The laparoscopic technique results in both shorter time to full recovery and shorter time to return to work, at the price of substantially increased costs. PMID:10450737

Ventral and incisional hernias are common surgical problems and their repairs are among the common surgeries done by a general surgeon. Repair of a large ventral hernia is still associated with high postoperative morbidity and recurrence rates. No single approach to ventral hernia repair will be the best choice for all patients. Large ventral hernias are often better approached with open surgery but may still be problematic when the defect is too wide for primary fascial closure to be achieved, as this leaves mesh exposed, bridging the gap. Techniques for incisional hernia repair have evolved over many years, and the use of mesh has reduced recurrence rates dramatically. The use of polypropylene mesh is reported to be associated with long-term complications such as severe adhesions and enterocutaneous fistula, which occur more commonly if the mesh is applied intraperitoneally with direct contact of the serosal surface of the intestine. Composite meshes containing expanded polytetrafluoroethylene (ePTFE) have been used recently; their major drawbacks lie in their high cost, inferior handling characteristics, and poor incorporation into the tissues. Although several studies have clearly demonstrated the safety and efficacy of prosthetic mesh repair in the emergency management of the incarcerated and/or strangulated inguinal and ventral hernias, however, surgeons remained reluctant to use prosthetics in such settings. The aim of this work was to evaluate the effectiveness and safety of placing the omentum and/or the peritoneum of the hernia sac as a protective layer over the viscera in the emergency repair of large ventral hernias using on-lay polypropylene mesh whenever complete tension-free closure of the abdominal wall was impossible. This study was carried out on all patients with large ventral hernia presented to the Gastrointestinal Surgery Unit, Main Alexandria University Hospital in an emergency situation during the period from October 2005 till October 2012

Surgery for refractory gastroesophageal reflux disease (GERD) and hiatal hernia leads to recurrence or persisting dysphagia in a minority of patients. Redo antireflux surgery in GERD and hiatal hernia is known for higher morbidity and mortality. This study aims to evaluate conventional versus robot-assisted laparoscopic redo antireflux surgery, with the objective to detect possible advantages for the robot-assisted approach. A single institute cohort of 75 patients who underwent either conventional laparoscopic or robot-assisted laparoscopic redo surgery for recurrent GERD or severe dysphagia between 2008 and 2013 were included in the study. Baseline characteristics, symptoms, medical history, procedural data, hospital stay, complications and outcome were prospectively gathered. The main indications for redo surgery were dysphagia, pyrosis or a combination of both in combination with a proven anatomic abnormality. The mean time to redo surgery was 1.9 and 2.0 years after primary surgery for the conventional and robot-assisted groups, respectively. The number of conversions was lower in the robot-assisted group compared to conventional laparoscopy (1/45 vs. 5/30, p = 0.035) despite a higher proportion of patients with previous surgery by laparotomy (9/45 vs. 1/30, p = 0.038). Median hospital stay was reduced by 1 day (3 vs. 4, p = 0.042). There were no differences in mortality, complications or outcome. Robotic support, when available, can be regarded beneficial in redo surgery for GERD and hiatal hernia. Results of this observational study suggest technical feasibility for minimal-invasive robot-assisted redo surgery after open primary antireflux surgery, a reduced number of conversions and shorter hospital stay.

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

A physical model of the abdomen can be a clean and cheap surrogate environment to assess new and existing closure solutions for post-laparoscopic wound closure, but a particular challenge is finding a surrogate material to replicate intestines which may protrude through a hernia. The literature shows no focus on this topic, and this paper therefore presents an investigation of the extrusion properties of fresh porcine intestines compared to a number of potential surrogate materials: silicone, edible gelatine, dough and reconstituted powdered potatoes (RPP). An extrusion rig was developed to simulate the mechanical environment of a post-operative hernia formation. Displacement controlled extrusion tests were performed, and the force-extrusion relationships at different extrusion velocities were compared for the intestines and the surrogate materials. The intestines showed a peak extrusion force ranging from 9 N to 14.8 N when pushed through a 13 mm hole, and similar extrusion properties between cleaned and uncleaned fresh porcine intestines were observed. The tests on surrogate materials showed that the surface tension properties of silicone gel resulted in high friction, that edible gelatine extruded like a liquid and that dough is very stiff, rendering all three materials unsuitable for use as surrogates. However, the RPP mix showed very similar force-extrusion properties compared to both the cleaned and uncleaned intestines. Viscoelastic testing (7.5 mm/min, 15 mm/min and 30 mm/min) showed little rate dependency in the extrusion properties for either the porcine intestines or the RPP. Despite the complexity of intestinal tissue and the obvious physical differences between intestine and RPP, it was found that there is no statistical difference between the yield strength of intestines and RPP (P values ranged between 0.14 and 0.3) at the rates tested.

Laparoscopic and endoscopic procedures generally are accepted for repair of primary and recurrent hernias that follow conventional (anterior) repair. This report discusses transabdominal preperitoneal (TAPP) for incarcerated hernias, scrotal hernias, and hernias after radical prostatectomy, as well as hernia recurrences after TAPP and totally extraperitoneal (TEP) procedures (complex hernias). Studies with long-term results of hernia recurrences are missing. This study aimed to determine hernia recurrence rates for adults after a modified TAPP procedure. The records of patients who had hernia repair surgery at a general hospital 2, 7, 12, and 17 years earlier were analyzed. Living patients were requested to complete a questionnaire to complement information from their hospital records. A retrospective analysis was undertaken that included 5,764 patients who had undergone hernia repair surgery 2-17 years earlier at a single large center. Between 1993 and 2009, a modified TAPP procedure was performed for 5,764 patients (median age, 59.1 years) to repair 6,776 hernias (93.9% of all hernia repairs), including 6,126 primary hernias (87.4%) and 884 recurrent hernias (12.6%). These included 994 complicated hernias (14.2%) closed by a modified TAPP (89.3% of all femoral hernias, 85.9% of scrotal hernias, 79.1% of incarcerated hernias, and 92.7% of hernias after radical prostatectomy). Limited financial and staff resources did not permit a quantitative follow-up study within a reasonable time of all 5,764 patients who had hernia surgery 2-18 years earlier. To obtain quantitative results of hernia recurrences after a modified TAPP, the patients were divided into four subgroups and requested to complete a questionnaire. These four patient subgroups whose surgeries had been performed 2 years earlier (241 patients with 277 hernias), 7 years earlier (285 patients with 376 hernias), 12 years earlier (401 patients with 544 hernias), and 17 years earlier (181 patients with 222

This study reports a 69-year-old, obese, female patient presenting with a biliary leakage after laparoscopic cholecystectomy for cholelithiasis. Closure of the umbilical trocar site had been neglected during the laparoscopic cholecystectomy. Early, on postoperative day five, endoscopic retrograde cholangiopancreatography (ERCP) requirement after laparoscopic cholecystectomy resolved the biliary leakage problem but resulted with a more complicated clinical picture with an intestinal obstruction and severe abdominal pain. Computed tomography revealed a strangulated hernia from the umbilical trocar site. Increased abdominal pressure during ERCP had strained the weak umbilical trocar site. Emergency surgical intervention through the umbilicus revealed an ischemic small bowel segment which was treated with resection and anastomosis. This report demonstrates that negligence of trocar site closure can result in very early herniation, particularly if an endoscopic intervention is required in the early postoperative period.

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.

The majority of current literature regarding laparoscopic inguinal hernia repair group all their pediatric patients together. This study aimed to evaluate the long-term outcomes of patients who underwent laparoscopic intracorporeal inguinal hernia ligation under the age of 1 year to ascertain if there were hidden advantages or limitations in this particular group. Patients under the age of 1 year at time of laparoscopic intracorporeal inguinal hernia ligation by a single pediatric surgeon were identified. Data were obtained from case notes, hospital electronic records, and parental telephone consultation. One hundred fourteen patients under the age of 1 year underwent laparoscopic inguinal hernia repair from November 2003 to October 2010. The male:female ratio was 4:1. The mean corrected age at surgery was 15.5 (range, 3-42) weeks, and the mean weight at surgery was 5.3 (range, 1.9-9.8) kg. All patients' case notes and electronic records were accessed. Forty-two percent of parents were contactable (mean of 4 years following surgery). There was one recurrence on the asymptomatic side in a boy that presented 3 years later. Five patients required orchidopexy following laparoscopic hernia repair, although 3 cases were known to be undescended at the time of surgery. One patient had intermittent ipsilateral groin swelling that resolved spontaneously after 6 months. Laparoscopic intracorporeal inguinal hernia ligation in patients under the age of 1 year is safe and effective. Recurrence rates may be lower than those in patients under 1 year of age undergoing a traditional open repair. However, there may be a higher rate iatrogenic of cryptorchidism in this laparoscopic group.

Laparoscopic hernia repair has all the advantages of a tension free repair. This study compares the laparoscopic transabdominal preperitoneal (TAPP) approach with tension-free open hernia repair in terms of operative time, postoperative pain, hospital stay, complications, and cost. Open and TAPP repairs using polypropylene mesh were performed in two groups of 25 male patients. The difference in operative times between the groups was not significant. Mean pain scores (0-100) for the open group were 54.12 +/- 13.06 at 12 hours and 37.24 +/- 11.38 at 24 hours, significantly higher than the corresponding scores of 38.36 +/- 8.21 at 12 hours and 20.92 +/- 8.73 at 24 hours for the TAPP group (P < 0.05). The mean postoperative analgesic dose was 6.72 +/- 2.72 in the TAPP group, which was insignificantly lower than 7.52 +/- 2.00 in the open group. Mean hospital stay was 2.24 +/- 0.97 days in the open group and 1.52 +/- 0.51 in the TAPP group, which was significant (P < 0.05). Twenty patients (80%) in the TAPP group rated themselves highly satisfied with the surgery as compared to 11 patients (44%) in the open group (P < 0.05). There was no recurrence in either group during a mean followup period of 13.5 months (range, 8-28 months). Laparoscopic hernia repair was significantly more expensive than open (1100 US dollars versus 629 US dollars). TAPP repair is superior to open repair in terms of shorter hospital stay, lower postoperative pain, and better patient satisfaction. It is also safe, with no recurrence in a short-term period. This technique will be the operation of choice for the treatment of groin hernia after long-term results have been established in our center.

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.

Transversus abdominis release (TAR) is a safe, effective strategy to repair complex ventral incisional hernia (VIH); however, open TAR (o-TAR) often necessitates prolonged hospitalization. Robot-assisted TAR (r-TAR) may benefit short-term outcomes and shorten convalescence. This study compares 90-day outcomes of o-TAR and r-TAR for VIH repair. A single-center, retrospective review of patients who underwent o-TAR or r-TAR for VIH from 2015 to 2016 was conducted. Patient and hernia characteristics, operative data, and 90-day outcomes were compared. The primary outcome was hospital length of stay, and secondary metrics were morbidity, surgical site events, and readmission. Overall, 102 patients were identified (76 o-TAR and 26 r-TAR). Patients were comparable regarding age, gender, body mass index, and the presence of co-morbidities. Diabetes was more common in the open group (22.3 vs. 0%, P = 0.01). Most VIH defects were midline (89.5 vs. 83%, P = 0.47) and recurrent (52.6 vs. 58.3%, P = 0.65). Hernia characteristics were similar regarding mean defect size (260 ± 209 vs. 235 ± 107 cm(2), P = 0.55), mesh removal, and type/size mesh implanted. Average operative time was longer in the r-TAR cohort (287 ± 121 vs. 365 ± 78 min, P < 0.01) despite most receiving mesh fixation with fibrin sealant alone (18.4 vs. 91.7%, P < 0.01). r-TAR trended toward lower morbidity (39.2 vs. 19.2%, P = 0.09), less severe complications, and similar rates of surgical site events and readmission (6.6 vs. 7.7%, P = 1.00). In addition, r-TAR resulted in a significantly shorter median hospital length of stay compared to o-TAR (6 days, 95% CI 5.9-8.3 vs. 3 days, 95% CI 3.2-4.3). In select patients, the robotic surgical platform facilitates a safe, minimally invasive approach to complex abdominal wall reconstruction, specifically TAR. Robot-assisted TAR for VIH offers the short-term benefits of low morbidity and decreased hospital length of stay compared to open TAR.
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).

Intestinal occlusion by internal hernia is not a rare complication (0.2%-5%) after Laparoscopic Roux-en-Y-GBP (LGBP) with higher morbidity and mortality related to mesenteric vessels involvement. In our Center, from October 2009 to April 2013 we have had 17 pts treated for internal hernia on 412 LGBP (4.12%). Clinical case: 28-year-old woman, operated of LGBP (BMI = 49; co-morbidity: diabetes mellitus and arthropathy) about 10 mo before, was affected by recurrent abdominal pain with alvus alteration lasting for a week. After vomiting, she went to first aid Unit of a peripheric hospital where she made blood tests, RX and US of abdomen that resulted normal so she was discharged with flu like syndrome diagnosis. After 3 d the patient contacted our Center since her symptoms got worse and was hospitalized. Blood tests showed an alteration of hepatic enzymes and amylases. The abdominal computed tomography (CT) showed the presence of fluid in peri-splenic, peri-hepatic areas and in pelvis and a “target like imagine” of “clustered ileal loops” with a superior mesenteric vein (SMV) thrombosis involving the Portal Vein. During the operation, we found a necrosis of 80 cm of ileus (about 50 cm downstream the jejuno-jejunal anastomosis) due to an internal hernia through Petersen’s space causing a SMV thrombosis. The necrotic bowel was removed, the internal hernia was reduced and Petersen’ space was sutured by not-absorbable running suture. An anticoagulant therapy was begun in the post-operative time and the patient was discharged after 28 d. Conclusions: The internal hernia diagnosis is rarely confirmed by preoperative exams and it is obtained in most cases by laparoscopy but the improvement of technologies and the discover of “new” CT signs interpretation can address to an early laparoscopic treatment for high suspicion cases.

Foramen of Winslow hernia (FWH) is a rare and often overlooked diagnosis with a high mortality rate. Widespread availability of cross-sectional imaging allows early diagnosis and prompt management. In this setting, before ischemia occurs, explorative laparoscopy would be the most suitable approach. Experience, however, remains sparse, and technical difficulties may be encountered. This is the case of a 38-year-old Caucasian woman who presented to the emergency department for a sudden epigastric pain. Physical exam was unremarkable, and routine blood tests were within normal range. An abdominal computed tomography (CT) scan confirmed the diagnosis of ileocaecal herniation through the foramen of Winslow. Under urgent laparoscopy, the caecum appeared viable but incarcerated in the lesser sac. Caecal puncture was the key to achieving atraumatic reduction of the hernia and bowel salvage.

Laparoscopic mesh fixation using a stapler can lead to complications such as nerve injury and bowel injury. However, mesh fixation by suturing with conventional laparoscopic instruments (CLI) is difficult because of limited degrees of freedom. A manual manipulator--Radius Surgical System (Radius)--whose tip can deflect and rotate, gives the surgeon two additional degrees of freedom. The aim of this study is to evaluate the introduction of Radius to mesh fixation in laparoscopic inguinal hernia repair. A model for inguinal hernia repair was prepared using animal organs in a trainer. Mesh fixation was performed using Radius, stapler, and CLI. Tensile strength during extraction of mesh toward the vertical direction, and execution time, were measured. The mean number of fixation points of Radius, stapler, and CLI was 9.3 +/- 1.5, 8.5 +/- 1.4, and 9.0 +/- 1.0, respectively. The mean tensile strength of fixation of mesh of Radius, stapler, and CLI was 140.7 +/- 48.9, 73.1 +/- 23.4, and 53.6 +/- 31.5 (N), respectively. The mean tensile strength per one fixation point by Radius, stapler, and CLI was 16.5 +/- 5.3, 8.7 +/- 2.8, and 6.3 +/- 3.6 (N), respectively. The mean execution time of Radius, stapler, and CLI was 479 +/- 108, 54 +/- 31, and 431 +/- 77 (sec), respectively. The mesh fixation by Radius was stronger than that by staples and CLI. Two additional degrees of freedom were useful in difficult angles. The introduction of Radius is feasible and facilitates the fixation of mesh with sutures in laparoscopic inguinal hernia repair.

This report reviews our experience with 3530 transabdominal preperitoneal (TAPP) hernia repairs in 3017 patients (513 bilateral) over the 7-year period from May 1992 to July 1999. We have continually audited our practice and modified the techniques in response. Unless contraindicated, laparoscopic TAPP repair is considered the procedure of choice at our institution for all reducible inguinal hernias. We initially stapled an 11 x 6 cm polypropylene mesh in the preperitoneal space but now place a 15 x 10 cm mesh in the preperitoneal space with sutured peritoneal closure. There have been a total of 22 recurrences, of which 17 were identified in the first 325 repairs (5%) using the 11 x 6 cm mesh. Five recurrences occurred in the later 3205 repairs (0.16%) (median follow up of 45 months). There was one 30-day death unrelated to the procedure. There have been seven conversions (four due to irreducibility, two due to extensive adhesions, one due to bleeding). Bladder perforations have occurred in seven cases, of which six were recognized immediately and treated laparoscopically without sequelae. There have been seven cases of small bowel obstruction from herniation through the peritoneal closure. Sutured repair of the peritoneum has reduced the incidence of this complication. Four patients had mesh infections, of whom three were treated conservatively. The incidence of postoperative seroma and hematoma was 8%. Median operation time remains at 40 min with a mean hospitalization of 0.9 nights. Sixty percent of TAPP hernia repairs are now performed on the Day Surgical Unit with a 3% admission rate. Median return to normal activities is 7 days. Forty percent of patients require no postoperative analgesia. These figures remain the same whether the hernia is primary, recurrent, unilateral, or bilateral. Consultants performed most operations early in the series, but latterly surgical trainees have performed the majority of these procedures under supervision. Laparoscopic TAPP

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

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.

Hernias after orthotopic liver transplant (OLT) occur in about 30 % of cases. Predisposing factors in liver cirrhotic patients of cases are ascites, low abdominal muscle mass and cachexia before and immunosuppression after OLT. Standard operative transplant-technique even in small hernias is to implant a mesh. For patients after liver transplantation a porcine non-cross linked biological patch being less immunogenic than synthetic and cross-linked meshes is chosen for ventral incisional hernia repair. 3 patients (1 female, 2 male), OLT indications Hepatitis C, exogenous- toxic cirrhosis, median-age 53 (51 - 56) and median time to hernia occurrence after OLT were 10 month (6 - 18 m) are documented. 2 patients suffered from diabetes, 2 from chronic-obstructive lung disease. Maintenance immunosuppressions were Everolimus in 1 patient, Everolimus + MMF in the second and Everolimus +Tacrolimus in the third patient. The biological was chosen for hernia repair due to the preexisting risk- factors. Meshes, 10 × 16 cm were placed, in IPOM (Intra-Peritonel-Onlay-Mesh) -position by relaparatomy. Insolvable, monofile, interrupted sutures were used. All patients recovered primarily, and were dismissed within 10 d post OP. No wound healing disorders or signs of postoperative infections occurred. All are free of hernia recurrence in a mean observation time of 22 month (10 - 36). The usage of porcine non-cross-linked biological patches seems feasible for incisional hernia repair after OLT. Wound infections in these patients have been observed with other meshes. Further investigation is needed to prove potential superiority of this biological to the other meshes. © Georg Thieme Verlag KG Stuttgart · New York.

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.

Large ventral hernias (VH) following conservative treatment of a giant omphalocele are a major challenge for pediatric surgeons. Although primary closure is accepted as the ideal procedure, these defects often require multi-staged operations, prosthetic support, and postoperative mechanical ventilation. Between 1990 and 2000, 34 patients with omphaloceles were admitted to our unit and 6 of them (17.6%) who had giant omphaloceles were treated conservatively. In the same period, a 5-year-old girl was admitted with a huge VH following application of subcutaneous tissue expanders in another center. In these 7 patients (6 girls, 1 boy, average age 20 months) we used preoperative elastic bandaging for facilitating primary closure. In all cases primary closure was successful following 3 to 6 weeks of bandaging. We did not use prosthetic material or postoperative mechanical ventilation in any case. Follow-up periods ranged from 2 to 10 years, and there were no recurrences or other problems. Out limited experience reveals that preoperative elastic bandaging is a safe and effective procedure for facilitating primary closure of the large VHs.

Prophylactic incisional negative-pressure wound therapy use after ventral hernia repairs (VHRs) remains controversial. We assessed the impact of a modified negative-pressure wound therapy system (hybrid-VAC or HVAC) on outcomes of open VHR. A 5-year retrospective analysis of all VHRs performed by a single surgeon at a single institution compared outcomes after HVAC versus standard wound dressings. Multivariable logistic regression compared surgical site infections, surgical site occurrences, morbidity, and reoperation rates. We evaluated 199 patients (115 HVAC vs 84 standard wound dressing patients). Mean follow-up was 9 months. The HVAC cohort had lower surgical site infections (9% vs 32%, P < .001) and surgical site occurrences (17% vs 42%, P = .001) rates. Rates of major morbidity (19% vs 31%, P = .04) and 90-day reoperation (5% vs 14%, P = .02) were lower in the HVAC cohort. The HVAC system is associated with optimized outcomes following open VHR. Prospective studies should validate these findings and define the economic implications of this intervention. Copyright © 2015 Elsevier Inc. All rights reserved.

The use of a self-expanding nitinol framed prosthesis (ReboundHRD(®)) for totally extraperitoneal laparoscopic inguinal hernia repair (TEP-IHR) could solve issues of mesh shrinkage and associated pain. We prospectively evaluated the use of the ReboundHRD(®) mesh for TEP-IHR. All patients who underwent a TEP-IHR using the ReboundHRD(®) Large mesh from April 2014 till May 2015, were included. No mesh fixation was performed. Follow-up assessments were performed at the day of surgery, 1, 2, and 7 days, 1, 3, 6, and 12 months. Outcome measures include post-operative pain (visual analogue scale, VAS), operative details, complications, and recurrence rate. In total, 69 TEP-IHR procedures were performed in 54 patients (15 bilateral hernias). No perioperative and 5 (9%) postoperative complications occurred, all graded Clavien-Dindo I-II. The median length of stay was 1 day (range 0-3), with 78% of the operations performed in an ambulatory setting. Median VAS score decreased from 3 (range 0-4) on the day of surgery to 1 (range 0-2) on day 7. Patients were completely pain-free at a median time of 5 (range 1-60) days. The majority (80.4%, 37/46) of the active patients went back to work within 2 weeks (maximum 6 weeks). At a median follow-up of 19 months (range 16-26 months), no recurrences occurred. TEP-IHR using a self-expanding nitinol framed hernia repair device is a safe technique in longterm follow-up. The technique is associated with a low incidence of postoperative pain, a short hospital stay and quick return to normal activities. Copyright © 2017 IJS Publishing Group Ltd.

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.

Diagnostic laparoscopy (DL) of the contralateral side during inguinal herniotomy via the hernia sack may avoid a subsequent second operation. Can this procedure however also reduce costs in the German health care system? Prospective analysis was performed of children operated on for inguinal hernia (IH) from March 2006 until October 2007. Using a linear mathematic model, the costs for different scenarios were calculated regarding the risk of contralateral IH. We thereby determined the incidence of contralateral IH at which DL became economically reasonable. A total of 123 unilateral IH operations (IH-OP) were performed in infants during the study period. Of these, 31 patients underwent DL of the contralateral side. Thirteen open hernia sacks were identified and ligated during the same operation. The following costs were calculated: (1) IH-OP without DL, 286 Euro, (2) IH-OP with contralateral DL, 338 Euro, (3) IH-OP with DL and synchronous ligation of the contralateral side, 393 Euro, and (4) metachronous operations of bilateral IH, 572 Euro. The incidence of contralateral hernia described in the literature ranges from 20% to 50%. Linear regression of the relative costs shows an economic advantage for DL with an incidence above 23%. Laparoscopic evaluation of the contralateral side in IH-OP is a rational approach for the patient and makes economic sense in the German health care system.

The use of mesh during ventral hernia repair (VHR) is a well-accepted concept. However, the ideal location of mesh placement remains strongly debated. Although VHR with onlay mesh placement has historically been associated with a high rate of wound events, this surgical approach is technically less challenging than VHR with sublay mesh placement. The purpose of this study was to compare 30-day wound events after onlay mesh placement with adhesive fixation vs those after sublay mesh placement using the Americas Hernia Society Quality Collaborative database. All patients undergoing elective, open VHR with synthetic mesh placement from January 2013 through January 2016 were identified within the Americas Hernia Society Quality Collaborative. Only patients with clean wounds were included. Patients were divided into 2 groups: onlay mesh placement with the use of adhesive and sublay mesh placement. The association of mesh location with 30-day wound events was investigated using a matched analysis. A total of 1,854 patients met inclusion criteria; 1,761 (95.0%) underwent sublay mesh placement and 93 (5.0%) underwent onlay mesh placement with the use of adhesive. A 2:1 sublay to onlay matched analysis was performed based on factors previously shown to influence wound events after VHR. After matching, both groups had a lower mean Ventral Hernia Working Group grade and fewer associated comorbidities. There was no statistically significant difference between the sublay and onlay groups with respect to 30-day surgical site infections (2.9% vs 5.5%; p = 0.30), surgical site occurrences (15.2% vs 7.7%; p = 0.08), or surgical site occurrences requiring procedural intervention (8.2% vs 5.5%; p = 0.42). Ventral hernia repair with onlay mesh placement is a safe alternative to VHR with sublay mesh placement in low-risk patients. Additional studies are needed to determine the long-term mesh outcomes and recurrence rates in both of these groups. Copyright © 2017 American College of

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

Numerous mesh materials are available for laparoscopic inguinal hernia repair. The role of fixation of mesh in laparoscopic inguinal hernia repair remains controversial. Mesh materials have been engineered to anatomically conform to the pelvis to potentially reduce or eliminate the need for fixation. This study evaluates the outcomes of laparoscopic inguinal hernia utilizing a device consisting of a lightweight polypropylene mesh with a nitinol frame (Rebound HRD) compared with repair with lightweight polypropylene mesh with permanent tack fixation. A prospective randomized trial evaluating the outcomes of laparoscopic inguinal hernia repair with a lightweight polypropylene mesh with a nitinol frame (N-LWM) compared with standard lightweight polypropylene mesh (LWM) was conducted. Randomization was performed at an N-LWM to LWM ratio of 2:1. Repairs were standardized to a laparoscopic extraperitoneal approach without fixation for N-LWM and titanium tack fixation for LWM repairs. Follow-up assessments were performed at 7 days, 6 months, and 1 year. Outcome measures include visual analog pain scale (VAS), Short Form 36 (SF-36), Carolinas Comfort Scale (CCS), operative details, complications, and recurrences. There were 47 patients that underwent laparoscopic inguinal hernia repair and adhered to study protocol (31 N-LWM, 16 LWM). The groups did not differ significantly in age, body mass index, ethnicity, or employment. The N-LWM group had bilateral mesh placed in 51.6% and LWM 43.8% (P = .76). Operative duration was similar, 59.6 ± 23.1 minutes for LWM and 62.4 ± 26.7 minutes for N-LWM (P = .705) as was mesh handling time was 5.4 ± 3.1 minutes LWM versus 7.3 ± 3.9 minutes N-LWM (P = .053). VAS, CCS, and SF-36 survey results were similar between groups. There was one recurrence (0.03%) in the N-LWM group. Nitinol-framed lightweight polypropylene mesh may be safely used during laparoscopic inguinal hernia repair with outcomes comparable to LWM at 1 year. N-LWM does

Laparoscopic Roux-en-Y gastric bypass (LRYGB) is considered the golden standard for bariatric surgery. However, the potential risk for internal hernia after LRYGB remains a significant concern to both patients and surgeons. In addition, patients presenting with abdominal pain after LRYGB warrant careful attention to avoid missing or delaying the diagnosis of internal hernia. The aim of this study was to describe our technique to prevent internal hernia after LRYGB, intra-operative findings, and our management strategies for patients with internal hernia after LRYGB. In this video, we review different technical tips and tricks to explore patients with suspected internal hernia after RYGB, how to reduce obstructed small bowel, and effectively close mesenteric defects to prevent internal hernia after LRYGB. A high index of suspicion and evaluation of the CT scan of the patient by an experienced bariatric surgeon is essential to avoid missing cases of internal hernia after LRYGB. In addition, patients presenting with incarcerated small bowel due to an internal hernia are best managed by standing on the left side of the patient with the left arm tucked and starting at the ileocecal valve and running the small bowel backwards towards the ligament of Treitz. Furthermore, patients with bowel obstruction due to internal hernia may need to have a gastrostomy placed at the remnant of the stomach. Recurrent abdominal pain is not uncommon after LRYGB. Systematic closure of mesenteric defects, the use of diagnostic laparoscopy, and high index of suspicion are all necessary to avoid delay in diagnosis.

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.

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

To evaluate the short- and long-term results after a modified Chevrel technique for midline incisional hernia repair, regarding surgical technique, hospital stay, wound complications, recurrence rate, and postoperative quality of life. These results will be compared to the literature derived reference values regarding the original and modified Chevrel techniques. In this large retrospective, single surgeon, single centre cohort all modified Chevrel hernia repairs between 2000 and 2012 were identified. Results were obtained by reviewing patients' medical charts. Postoperative quality of life was measured using the Carolina Comfort Scale. A multi-database literature search was conducted to compare the results of our series to the literature based reference values. One hundred and fifty-five patients (84 male, 71 female) were included. Eighty patients (52%) had a large incisional hernia (width ≥ 10 cm) according the definition of the European Hernia Society. Fourteen patients (9%) underwent a concomitant procedure. Median length-of-stay was 5 days. Within 30 days postoperative 36 patients (23.2%) had 39 postoperative complications of which 30 were mild (CDC I-II), and nine severe (CDC III-IV). Thirty-one surgical site occurrences were observed in thirty patients (19.4%) of which the majority were seroma (16 patients 10.3%). There was no hernia-related mortality during follow-up. Recurrence rate was 1.8% after a median follow-up of 52 months (12-128 months). Postoperative quality of life was rated excellent. The modified Chevrel technique for midline ventral hernias results in a moderate complication rate, low recurrence rate and high rated postoperative quality of life.

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.

Generic instruments used for the valuation of health states (e.g., EuroQol) often lack sensitivity to notable differences that are relevant to particular diseases or interventions. We developed a valuation methodology specifically for complications following ventral incisional herniorrhaphy (VIH). Between 2004 and 2006, 146 patients were prospectively randomized to undergo laparoscopic (n = 73) or open (n = 73) VIH. The primary outcome of the trial was complications at 8 weeks. A three-step methodology was used to assign severity weights to complications. First, each complication was graded using the Clavien classification. Second, five reviewers were asked to independently and directly rate their perception of the severity of each class using a non-categorized visual analog scale. Zero represented an uncomplicated postoperative course, while 100 represented postoperative death. Third, the median, lowest, and highest values assigned to each class of complications were used to derive weighted complication scores for open and laparoscopic VIH. Open VIH had more complications than laparoscopic VIH (47.9 vs. 31.5%, respectively; P = 0.026). However, complications of laparoscopic VIH were more severe than those of open VIH. Non-parametric analysis revealed a statistically higher weighted complication score for open VIH (interquartile range: 0-20 for open vs. 0-10 for laparoscopic; P = 0.049). In the sensitivity analysis, similar results were obtained using the median, highest, and lowest weights. We describe a new methodology for the valuation of complications following VIH that allows a direct outcome comparison of procedures with different complication profiles. Further testing of the validity, reliability, and generalizability of this method is warranted.

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

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

External and internal rectal prolapse with their affiliated rectocele and enterocele, are associated with debilitating symptoms such as obstructed defecation, pelvic pain and faecal incontinence. Since perineal procedures are associated with a higher recurrence rate, an abdominal approach is commonly preferred. Despite the description of greater than three hundred different procedures, thus far no clear superiority of one surgical technique has been demonstrated. Ventral mesh rectopexy (VMR) is a relatively new and promising technique to correct rectal prolapse. In contrast to the abdominal procedures of past decades, VMR avoids posterolateral rectal mobilisation and thereby minimizes the risk of postoperative constipation. Because of a perceived acceptable recurrence rate, good functional results and low mesh-related morbidity in the short to medium term, VMR has been popularized in the past decade. Laparoscopic or robotic-assisted VMR is now being progressively performed internationally and several articles and guidelines propose the procedure as the treatment of choice for rectal prolapse. In this article, an outline of the current status of laparoscopic and robotic ventral mesh rectopexy for the treatment of internal and external rectal prolapse is presented. PMID:27275090

Outcomes after ventral incisional hernia (VIH) repair are measured by recurrence rate and subjective measures. No objective metrics evaluate functional outcomes after abdominal wall reconstruction. This study aimed to develop testing of abdominal wall strength (AWS) that could be validated as a useful metric. Data were prospectively collected during 9 months from 35 patients. A total of 10 patients were evaluated before and after VIH repair, for a total of 45 encounters. The patients were tested simultaneously or in succession by two of three examiners. Data were collected for three tests: double leg lowering (DLL), trunk raising (TR), and supine reaching (SR). Raw data were compared and tested for validity, and continuous data were transformed to categorical data. Agreement was measured using the intraclass correlation coefficient (ICC) for DLL and using kappa for the ordinal measures. Simultaneous testing yielded the following interobserver reliability: DLL (0.96 and 0.87), TR (1.00 and 0.95), and SR (0.76). Reproducibility was assessed by consecutive tests, with correlation as follows: DLL (0.81), TR (0.81), and RCH (0.21). Due to poor interobserver reliability for the SR test compared with the DLL and TR tests, the SR test was excluded from calculation of an overall score. Based on raw data distribution from the DLL and TR tests, the DLL data were categorized into 10º increments, allowing construction of a 10-point score. The median AWS score was 5 (interquartile range [IQR], 4-7), and there was agreement within 1 point for 42 of the 45 encounters (93%). The findings from this study demonstrate that the 10-point AWS score may measure AWS in an accurate and reproducible fashion, with potential for objective description of abdominal wall function of VIH patients. This score may help to identify patients suited for abdominal wall reconstruction while measuring progress after VIH repair. Further longitudinal outcomes studies are needed.

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.

Large complex ventral hernias act as tissue expanders for skin and subcutaneous fat. The purpose of this study is to evaluate outcomes of total abdominal wall reconstruction with component separation, posterior reinforcement, and vertical abdominoplasty in patients with large complex ventral hernias. Between 2010 and 2014, 58 patients underwent total abdominal wall reconstruction with component separation, intra-abdominal reinforcement, and vertical abdominoplasty. Between 2010 and 2012, patients underwent the conventional technique of component separation, while a perforator-preserving technique was performed during 2013 and 2014. Reinforcement material used was either synthetic mesh in clean cases or biologic mesh if contamination was present. All of the excessive skin and subcutaneous fat was removed in a vertical fashion. Data were analyzed with Mann-Whitney's U test or Fisher's exact test, as indicated. There were 27 moderately complex and 31 majorly complex hernias. Mean hernia size was 16 × 12 cm. The mean size of the removed skin island was 21 × 12 cm. Patients with contamination during the repair had longer in-hospital stays. Overall the local wound complication rate was 24 %, and was lower with the perforator-preserving technique compared to the conventional technique of component separation (11 vs. 48 %; OR 0.13, CI 0.03-0.5; p = 0.003). The overall postoperative morbidity rate was higher in the presence of contamination, and in patients with lower preoperative serum albumin levels. Mean total follow-up was 14 months with a 1-year recurrence-free survival of 96 %. This journal requires that authors assign a level of evidence to each article.

There is an increasing interest in patient-reported outcome measurement to evaluate hernia operations. Several hernia-specific quality of life (QoL) scales have been proposed, but none are constructed for preoperative assessment. The European Registry for Abdominal Wall Hernias (EuraHS) proposed the short, 9-question EuraHS-QoL instrument for assessment pre- and postoperatively. The EuraHS-QoL was evaluated in a prospective, multicenter validation study alongside the Visual Analogue Scale, Verbal Rating Scale, and Carolina Comfort Scale (https://clinicaltrials.gov; NCT01936584). We included 101 patients undergoing unilateral laparoscopic inguinal hernia repair with ProGrip laparoscopic, self-fixating mesh. Clinical follow-up at 12 months was 87% complete. The EuraHS-QoL score shows good internal consistency (Cronbach's α ≥ .90), good test-retest reliability (Spearman correlation coefficient r ≥ 0.72), and high correlation for pain with the Visual Analogue Scale, the Verbal Rating Scale, the Carolina Comfort Scale pain scale (r between 0.64 and 0.86), and for restriction of activity with the Carolina Comfort Scale movement scale (r between 0.65 and 0.79). Our results show significant improvement in quality of life at 3 weeks compared with preoperative and further significant improvement at 12 months (P < .05). No late complications or recurrences were recorded. An operation was performed in day surgery (>75%) or with a <24-hour admission (>95%) in the majority of the patients. The EuraHS-QoL instrument is a short and valid patient-reported outcome measurement following groin hernia repair. Laparoscopic inguinal hernia repair with ProGrip laparoscopic, self-fixating mesh results in a favorable outcome and significant improvement of quality of life compared with the preoperative assessment.

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.

To systematically review randomized controlled trials, (RCT) evidence comparing Lichtenstein to total extraperitoneal (TEP) hernia repair in terms of clinical and cost effectiveness. Case series. The study was conducted at University of Abderdeen, U.K. A comprehensive online literature search was undertaken using databases such as MEDLINE, PubMed, EMBASE and Springerlink. Studies were then shortlisted according to the selection criteria (RCT with over 100 subject and English language publications from 1995 onwards) and appraised using the SIGN Methodology Checklist. A metaanalysis of the data was also performed using RevMan software. Analysis of reported data shows that TEP has less postoperative pain and return to work than Lichtenstein method. Operation time is shown to be longer in the TEP but this difference is shortened with increasing surgeon experience. The meta-analysis of the data on complications shows that there are no significant differences between the two types of procedures. TEP causes more short-term recurrences which are attributed to the learning curve effect. Longterm recurrence rates on the other hand show no significant differences. At present TEP is slightly more expensive than Lichtenstein repair. Both TEP and Lichtenstein repair are clinically effective procedures. The choice between them should be made on a case-by-case basis; which depends on the patients' preference and characteristics such as age, work and health status.

Background Ventral incisional hernias (VIH) develop in up to 20% of patients following abdominal surgery. No widely applicable pre-operative risk-assessment tool exists. We aim to develop and validate a risk-assessment tool to predict VIH following abdominal surgery. Study Design A prospective study of all patients undergoing abdominal surgery was conducted at a single institution from 2008-2010. Variables were defined in accordance with the National Surgical Quality Improvement Project. VIH was determined through clinical and radiographic evaluation. A multivariate Cox proportional hazard model was built from a development cohort (2008-2009) to identify predictors of VIH. The HERNIAscore was created by converting the hazards ratios (HR) to points. The predictive accuracy was assessed on the validation cohort (2010) using a receiver operator characteristic curve and calculating the area under the curve (AUC). Results Of 625 patients followed for a median of 41(0.3-64 months), 93(13.9%) developed a VIH. The training cohort (n=428, VIH=70,16.4%) identified four independent predictors: laparotomy (HR 4.77, 95%CI 2.61-8.70) or hand-assisted laparoscopy (HR=4.00, 95% CI 2.08-7.70), COPD (HR=2.35; 95%CI 1.44-3.83), and BMI≥25 (HR=1.74; 95% CI 1.04-2.91). Factors that were not predictive included age, gender, ASA score, albumin, immunosuppression, prior surgery, and suture material/technique. The predictive score had an AUC=0.77(95%CI0.68-0.86) using the validation cohort (n=197, VIH=23,11.6%). Using the HERNIAscore--HERNIAscore=4*Laparotomy+3*HAL+1*COPD+1* BMI≥25--three classes stratified the risk of VIH: Class I (0-3 points):5.2%, Class II (4-5 points):19.6%, and Class III (6 points):55.0%. Conclusions The HERNIAscore accurately identifies patients at increased risk for VIH. While external validation is needed, this provides a starting point to counsel patients and guide clinical decisions. Increasing the use of laparoscopy, weight-loss programs, community smoking

Variables were defined in accordance with the National Surgical Quality Improvement Project, and VIH was determined through clinical and radiographic evaluation. A multivariate Cox proportional hazard model was built from a development cohort (2008 to 2009) to identify predictors of VIH. The HERNIAscore was created by converting the hazards ratios (HR) to points. The predictive accuracy was assessed on the validation cohort (2010) using a receiver operator characteristic curve and calculating the area under the curve (AUC). Of 625 patients followed for a median of 41 months (range 0.3 to 64 months), 93 (13.9%) developed a VIH. The training cohort (n = 428, VIH = 70, 16.4%) identified 4 independent predictors: laparotomy (HR 4.77, 95% CI 2.61 to 8.70) or hand-assisted laparoscopy (HAL, HR 4.00, 95% CI 2.08 to 7.70), COPD (HR 2.35; 95% CI 1.44 to 3.83), and BMI ≥ 25 kg/m(2) (HR1.74; 95% CI 1.04 to 2.91). Factors that were not predictive included age, sex, American Society of Anesthesiologists (ASA) score, albumin, immunosuppression, previous surgery, and suture material or technique. The predictive score had an AUC = 0.77 (95% CI 0.68 to 0.86) using the validation cohort (n = 197, VIH = 23, 11.6%). Using the HERNIAscore: HERNIAscore = 4(∗)Laparotomy+3(∗)HAL+1(∗)COPD+1(∗) BMI ≥ 25, 3 classes stratified the risk of VIH: class I (0 to 3 points),5.2%; class II (4 to 5 points),19.6%; and class III (6 points), 55.0%. The HERNIAscore accurately identifies patients at increased risk for VIH. Although external validation is needed, this provides a starting point to counsel patients and guide

Chronic post-operative pain (CPP) following laparoscopic inguinal hernia repair (LIHR) may cause significant morbidity and be more problematic than recurrence. Determining pre-operative risk may reduce morbidity. Our aim was to determine prevalence of CPP following LIHR and identify risk factors for its development. Data from patients undergoing LIHR (1996-2004) at one District General Hospital were collected, including demographics, body mass index, pre-operative pain, LIHR type (TEP or TAPP, primary/recurrent, unilateral/bilateral) and post-operative complications including CPP (pain lasting > or = 1 year). A total of 881 patients underwent LIHR (1,029 hernias). Of these, 523 (60%) patients completed the questionnaire, and 72/523 (13.8%) patients experienced CPP. Presence of pre-operative pain (P < 0.001), recurrent LIHR (P = 0.021) and age < 50 years (P < 0.001) were significantly correlated with CPP. Chronic post-operative pain following LIHR is more prevalent than recurrence. Pre-operative pain, surgery for recurrent inguinal hernias (following anterior repair) and younger age at surgery predict development of CPP. Identification of 'high-risk' patients may improve management, reducing morbidity and cost.

Paraesophageal hernia with intrathoracic mesentericoaxial type of gastric volvulus is a rare clinical entity. The rotation occurs because of the idiopathic relaxation of the gastric ligaments and ascent of the stomach adjacent to the oesophagus through the hiatus defect, while the gastroesophageal junction remains in the abdomen. The open approach remains the gold standard therapy for most patients. Here we report the case of a patient with such a condition who underwent a successful laparoscopic surgery. A literature search revealed that this is the first case report from Southeast Asia. A 55-year-old Chinese woman presented to us with symptoms suggestive of gastric outlet obstruction for one year. A chest radiograph showed an air bubble with air-fluid level in her left thoracic cavity, where a diaphragmatic hernia was initially suspected. A computed tomography scan and barium swallow study demonstrated the presence of a type III paraesophageal hernia with intrathoracic upside-down stomach. A laparoscopy was performed and the herniated stomach was successfully reduced into the abdomen. The mediastinal part of the hernial sac was excised. Adequate intraabdominal length of oesophagus was achieved after resection of the sac and circumferential oesophageal dissection. A lateral releasing incision was made adjacent to the right crus to facilitate crural closure. The diaphragmatic defect and the hiatal closure were covered with a composite mesh. A Toupet fundoplication was performed to recreate the antireflux valve. She had an uneventful recovery. She had no relapse of previous symptoms at her six-month follow-up assessment. Laparoscopic repair of such a condition can be accomplished successfully and safely when it is performed with meticulous attention to the details of the surgical technique.

Giant hiatal hernia (GHH) comprises 5% of hiatal hernia and is associated with significant complications. The traditional operative procedure, no matter transthoracic or transabdomen repair of giant hiatal hernia, is characteristic of more invasion and more complications. Although laparoscopic repair as a minimally invasive surgery is accepted, a part of patients can not tolerate pneumoperitoneum because of combination with cardiopulmonary diseases or severe posterior mediastinal and neck emphesema during operation. The aim of this article was to analyze our experience in gasless laparoscopic repair with abdominal wall lifting to treat the giant hiatal hernia. We performed a retrospective review of patients undergoing gasless laparoscopic repair of GHH with abdominal wall lifting from 2012 to 2015 at our institution. The GHH was defined as greater than one-third of the stomach in the chest. Gasless laparoscopic repair of GHH with abdominal wall lifting was attempted in 27 patients. Mean age was 67 years. The results showed that there were no conversions to open surgery and no intraoperative deaths. The mean duration of operation was 100 min (range: 90-130 min). One-side pleura was injured in 4 cases (14.8%). The mean postoperative length of stay was 4 days (range: 3-7 days). Median follow- up was 26 months (range: 6-38 months). Transient dysphagia for solid food occurred in three patients (11.1%), and this symptom disappeared within three months. There was one patient with recurrent hiatal hernia who was reoperated on. Two patients still complained of heartburn three months after surgery. Neither reoperation nor endoscopic treatment due to signs of postoperative esophageal stenosis was required in any patient. Totally, satisfactory outcome was reported in 88.9% patients. It was concluded that the gasless laparoscopic approach with abdominal wall lifting to the repair of GHH is feasible, safe, and effective for the patients who cannot tolerate the pneumoperitoneum.

The choice of approach to the laparoscopic repair of inguinal hernia is controversial. There is a scarcity of data comparing the laparoscopic transabdominal preperitoneal (TAPP) approach with the laparoscopic totally extraperitoneal (TEP) approach, and questions remain about their relative merits and risks. Electronic databases were searched to identify reports of trials comparing laparoscopic TAPP with laparoscopic TEP. In addition, selected conference proceedings were hand-searched, websites consulted, reference lists of all included papers were scanned, and experts contacted for other potentially eligible reports. All published and unpublished randomised controlled trials and quasi-randomised controlled trials comparing laparoscopic TAPP with laparoscopic TEP for inguinal hernia repair were eligible for inclusion. Large non-randomised prospective studies were also eligible for inclusion to provide further comparative evidence of complications and serious adverse events. Two reviewers independently extracted data and assessed study quality. Statistical analyses were performed using the fixed effects model and the results expressed as relative risk (RR) for dichotomous outcomes and weighted mean difference (WMD) for continuous outcomes with 95% confidence intervals (CI). The search identified one RCT which reported no statistically significant difference between TAPP and TEP when considering duration of operation, haematoma, length of stay, time to return to usual activities, and recurrence. The eight non-randomised studies suggest that TAPP is associated with higher rates of port-site hernias and visceral injuries whilst there appear to be more conversions with TEP. Vascular injuries and deep/mesh infections were rare and there was no obvious difference between the groups. No studies reporting economic evidence were identified. There is insufficient data to allow conclusions to be drawn about the relative effectiveness of TEP compared with TAPP. Efforts should be

Early post-operative pain after laparoscopic groin hernia repair may, as in other laparoscopic operations, have its own individual pain pattern and patient-related predictors of early pain. The purpose of this review was to characterise pain within the first post-operative week after transabdominal pre-peritoneal repair (TAPP) and total extraperitoneal repair (TEP), and to identify patient-related predictors of early pain. A qualitative systematic review was conducted. Pubmed, Embase, CINAHL, and the Cochrane database were searched for studies on early pain (first week) after TAPP or TEP. We included 71 eligible studies with 14,023 patients. Post-operative pain is most severe on day 0 and mainly on a level of 13-58 mm on a visual analogue scale and decreases to low levels on day 3. There seems to be no difference in pain intensity and duration when TEP and TAPP are compared. Deep abdominal pain (i.e. groin pain/visceral pain) dominates over superficial pain (i.e. somatic pain) and shoulder pain (i.e. referred pain) after TAPP. Predictors of early pain are young age and pre-operative high pain response to experimental heat stimulation. Furthermore, evidence supported early pain intensity as a predictive risk factor of chronic pain after laparoscopic groin hernia repair. Early pain within the first week after TAPP and TEP is most severe on the first post-operative day, and the pain pattern is dominated by deep abdominal pain. Early post-operative pain is most intense in younger patients and can be predicted by pre-operative high pain response to experimental heat stimulation. © 2012 The Authors.

We present the results of our first 44 laparoscopic incisional hernia repairs. This study examines the effectiveness of this technique in patients presenting with a first-time or recurrent incisional hernia. From October 2001 to November 2002, a total of 45 consecutive patients underwent laparoscopic incisional hernia repair with a new form of expanded polytetrafluoroethylene (ePTFE) mesh. Patient data, preoperative, intraoperative, and postoperative records, were recorded and analyzed. Mean defect size was 84 cm2, mean mesh size was 311 cm2, mean surgical time was 65 minutes, and mean hospital stay was 2.25 days. Postoperative complications occurred in four patients (9.1%). The laparoscopic approach is a safe, effective, and relatively complication-free option in the management of first-time and recurrent incisional hernias. The use of modified ePTFE mesh with a dual surface in incisional hernia repair enables early tissue attachment, reduces adhesions, and could reduce the incidence of recurrences.

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

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.

Little is known about the predictors of increased ambulatory costs following open ventral and incisional hernia repair (VIHR); however, postoperative complications would be expected to be associated with an increased burden on outpatient resources. The purpose of this study is to evaluate the impact of perioperative factors on outpatient resource utilization following VIHR. With IRB approval, the surgery scheduling system was queried to identify all cases of VIHR done at our institution over 3 years. Cases with other procedures done at time of VIHR were excluded. National Surgical Quality Improvement Program clinical data, physician billing data which included market and payor across cases, and medical record review data were combined and evaluated in order to quantify care and predictors of usage during the 6 months postoperatively. Data were analyzed for 308 patients. Median patient age was 52 years (SD = 13.3), and over half were female. The number of outpatient visits to the surgical office varied from 0 to 18 [median = 2; interquartile range (IQR) = 1-3]. CDC Wound Class >1 was associated with increase of mean 1.4 visits (IQR: 0.5-2.3); p = 0.003. Component separation, longer duration of operation, and increased mesh size were also predictive of increased number of office visits (p < 0.01). Postoperative infected seroma/seroma requiring drainage added a mean 2.3 visits (IQR: 1.3-3.3), (p < 0.001); and deep wound infection added a mean 3.9 visits (IQR: 1.9-5.9) (p < 0.001). Postoperative complications confer a significant burden for patients and to the outpatient surgical office. In an era in which improved quality and cost-efficiency has become imperative, measures to decrease risk of postoperative complications particularly for more complex VIHR would be expected to decrease resource utilization and increase value of care.

In ventral hernia repair, when prosthetic material is placed intraperitoneally, it may lead to an inflammatory reaction resulting in adhesions between the mesh and abdominal viscera. Several meshes have been developed to minimize this process. In this experimental study, the ability of different combined meshes to attenuate the adhesion formation was examined. Three commercially available lightweight porous combined meshes were placed intraperitoneally to repair an abdominal wall defect in rats: DynaMesh-IPOM (PVDF + PP), TiMesh (titanium-coated filament PP) and C-QUR/FX (omega-3 fatty acid-coated filament PP). The DynaMesh-CICAT (PVDF) was implanted in the control group. Adhesion formation was macroscopically evaluated and scored after 7 and 21 days. All animals except two presented intra-abdominal adhesions. None of the meshes examined in the study demonstrated to prevent adhesions. C-QUR/FX reduced adhesion formation at 7 days' follow-up compared with all other meshes but by 21 days this effect was diminished. Between 7 and 21 days adhesion extension significantly decreased for TiMesh. TAS did not show significant modifications between 7 and 21 days' follow-up for each mesh. The combined porous meshes tested in the present study demonstrated to reduce but not to prevent the adhesion formation, even if with some differences. Combined porous meshes could be chosen instead of simple meshes for retro-rectus preperitoneal prosthetic ventral hernia repair.

Wound complications including infection and necrosis remain common during complex open ventral hernia repair. Advancements or enhancements in imaging technology may abate some of these issues but requires more investigation. Laser-assisted fluorescent imaging with indocyanine green (Spy Elite, LifeCell Corporation, Branchburg, NJ) allows visualization and quantification of perfusion, facilitating management of poorly perfused tissue. Ten patients, who underwent large or massive ventral or incisional hernia repair with biologic graft reinforcement and either perforator-sparing components separation or primary open repair, underwent intraoperative laser-assisted fluorescent imaging with indocyanine green from August 2012 to August 2013. The cases were reviewed by an independent data collector with primary outcomes of postoperative skin infection and/or abdominal wall necrosis. Three (30%) patients had adequate perfusion, while seven (70%) patients had inadequate skin perfusion and necessitated excision of additional tissue. Of the patients whose ischemic tissue was removed, four (57%) patients had an infection and no patients developed necrosis postoperatively. Of the patients who had no removal of additional skin, one (33%) patient developed an infection and one (33%) patients developed skin necrosis. The intraoperative use of laser-assisted fluorescent imaging with indocyanine green may change management of abdominal wall flaps, even in perforator-sparing operations. Our study series is small and cannot suggest statistical significance in the potential benefit of intraoperative imaging, but shows that up to 70% of patients may require change in management due to poorly perfused tissue flaps.

The inability to reapproximate fascia in complex ventral hernia (CVH) repair remains challenging. Single-stage bridging reconstructions have been reported, however, with high rates of recurrence and wound complications. We describe a single-surgeon experience with bridging biologic CVH repair. We reviewed 37 patients undergoing CVH repair with bridging biologic mesh by the senior author from January 1, 2007 to January 1, 2013. Surgical history and operative characteristics were analyzed for predictors of hernia recurrence and wound complications. Average age was 53 ± 15 years, body mass index was 31.1 ± 8.1 kg/m(2), and history of prior repair in 18 patients. Common indications were trauma, intra-abdominal infection, and prior intra-abdominal surgery. Incidence of wound complications was 51.4%, most commonly wound breakdown and infection. With average follow-up of 13 months, recurrence rate was 18.9% at an average of 8.2 months postoperatively. Analysis demonstrated postoperative wound infection as the only predictor of recurrence (odds ratio = 22.1, P = .017). Hernia recurrence rate was 18.9% with bridged biologic CVH repairs, strongly associated with postoperative wound infection. This suggests that patients with postoperative infections may benefit from closer surveillance and more aggressive wound management. Copyright © 2015 Elsevier Inc. All rights reserved.

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.

The aims of this study were to compare same day discharges and early complications after open and laparoscopic primary paraumbilical hernia (PUH) repair, including the procedures performed by surgical trainees (STs). All patients who had open (suture or mesh) and laparoscopic repair of primary PUH in the Day Surgery Unit (DSU) between January 2007 and June 2009 were identified from the hospital database. The database was questioned regarding the grade of operating surgeon, type of surgical repair, day of admission and discharge from the DSU, and a patient's return to surgical services. Data were stored in Microsoft Excel(®) (TM 2007). Statistical significance was determined using Fisher's exact test. PUH was repaired in 337 patients: 252/337 (74.8 %) had open and 85/337 (25.2 %) had laparoscopic repair. Significantly, more patients were discharged home on the day of surgery after an open repair compared to the laparoscopic repair: open repair 187/252 (74.2 %), laparoscopic repair 35/85 (41.17 %), P = 0.0001. Overall early complications such as wound complications and hospital re-visits were similar in both groups: open repair 6.3 % (16/252), laparoscopic repair 11.7 % (10/85), P = 0.1554. STs performed 142/337 (42.1 %) of the PUH repairs with similar same day discharges from the DSU: STs 64.7 % (92/142), consultant surgeons 66.7 % (130/195), P = 0.7285. The difference in hernia recurrence between open repair 7/252 (2.78 %) and laparoscopic group 0/85 was not significant (P = 0.1985). Patients with PUH repair were more likely to go home on the day of surgery after open than after laparoscopic repair. This was not affected by the grade of the operating surgeon. Early complications were similar following open and laparoscopic repair of primary PUH.

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.

Laparoscopic incisional hernia repair (LIHR) is a common procedure requiring advanced laparoscopic skills. This study aimed to develop a procedure-specific tool to assess the performance of LIHR and to evaluate its reliability and validity. The Global Operative Assessment of Laparoscopic Skills-Incisional Hernia (GOALS-IH) is a 7-item global rating scale developed by experts to evaluate the steps of LIHR (placement of trocars, adhesiolysis, estimation of mesh size and shape, mesh orientation and positioning, mesh fixation, knowledge and autonomy in use of instruments, overall competence), each rated on a 5-point Likert scale. During LIHR, 13 attending surgeons and fellows experienced in minimally invasive surgery (MIS) and 19 novice surgeons (postgraduate years [PGYs], 3-5) were evaluated at four teaching hospitals by the attending surgeon, a trained observer, and self-assessment using GOALS-IH, and by a previously validated 5-item general laparoscopic rating scale (GOALS). Interrater reliability was assessed by intraclass correlation (ICC), and internal consistency of rating items was assessed by Cronbach's alpha. Known-groups construct validity was assessed by using the t-test and by correlating of the number of self-reported LIHR cases with the total score. Concurrent validity was assessed by correlating the GOALS-IH score with the GOALS general rating scale. Data are presented as mean and 95% confidence interval (CI). Interrater reliability for the total GOALS-IH score was 0.79 (95% CI, 0.60-0.89) between observers and attending surgeons, 0.81 (95% CI, 0.58-0.92) between participants and attending surgeons, and 0.89 (95% CI, 0.76-0.96) between participants and observers. Internal consistency was high (Cronbach's alpha, 0.93). Experienced surgeons performed significantly better than novices as assessed by GOALS-IH (31; 95% CI, 29-33 vs. 21; 95% CI, 19-24; p < 0.01). Very good correlation was found between GOALS-IH and previous LIHR experience (r = 0.82; p < 0

INTRODUCTION Internal herniation of a small bowel behind pelvic vessels is a rare complication seen after pelvic lymphadenectomy. PRESENTATION OF CASE A 56-year-old woman was operated due to a gynecological cancer. 4 years thereafter she presented with a 2 days history of abdominal pain and vomiting. Clinical and radiological findings indicated a small bowel obstruction. A loop of small bowel had herniated behind the left external iliac artery. Using laparoscopic technique the herniated bowel was reduced. Due to limited peritoneum around the area and skeletonized vessel, we decided not to do any repair of the hernia orifice. The postoperative recovery was uneventful, bowel activity returned to normal and she was discharged the next day. Follow-up was done at 1 month and the latest at 10 months. She didn’t experience pain or discomfort after the operation. DISCUSSION Due to limited peritoneum around the skeletonized vessel, we decided to leave the hernia orifice unrepaired. We found it hazardous to do any direct suture of the orifice or use a free peritoneal graft to repair the defect as the fibrosis and inflammatory process might have compromised the artery or the vein. A longer follow-up of the patient is needed to clearly conclude if this simple procedure has been sufficient. We agreed that if the patient would experience any sign of recurrence and need another operation we would close the defect at that time. CONCLUSION 4 years after pelvic lymphadenectomy a small bowel herniation behind an external iliac artery occurred. The patient was successfully treated with reduction of the small bowel using laparoscopic technique. A quick recovery with minimal discomfort and no sign of recurrence after 10 months made our approach an acceptable surgical option. PMID:24121051

Acute kidney injury (AKI) is a serious postoperative complication, negatively impacting mortality rates, extending length of stay, and raising hospital costs. The purpose of this study was to examine AKI following open ventral hernia repair (OVHR) using a large, heterogeneous database to determine the incidence and identify risk factors for this complication. Using the 2005-2012 ACS-NSQIP database, patients undergoing open ventral hernia repair were identified by CPT codes. Patients with acute kidney injury within 30 days of surgery were compared to controls by multivariate logistic regression across preoperative and intraoperative characteristics. Of 48,629 open ventral hernia repair patients identified in the dataset, AKI developed in 1.4% (681 patients). Multivariate logistic regression determined a number of factors associated with AKI. These include WHO Class III obesity (OR = 2.57, p < 0.001), history of cardiovascular disease (OR = 1.81, p < 0.001), diabetes (OR = 1.29, p = 0.028), hypoalbuminemia (OR = 1.42, p = 0.004), and chronic kidney disease (for a baseline GFR of 60-89 mL/min/1.73 m2, OR = 1.62, p = 0.001; for 30-59 mL/min/1.73 m2, OR = 2.25, p < 0.001; for 15-29 mL/min/1.73 m2, OR = 4.96, p < 0.001). Intraoperative factors include prolonged operative time (for ≥1 SD above the mean, OR = 1.68, p = 0.002; for ≥2SD above the mean, OR = 2.76, p < 0.001) and intraoperative transfusion (OR = 2.44, p < 0.001). Patients with a history of obesity, chronic kidney disease, cardiovascular history, diabetes, and hypoalbuminemia are at increased risk for AKI when undergoing OVHR. Intraoperative variables such as prolonged operative times and blood transfusions may also suggest increased risk. Preoperative identification of patients with these characteristics and perioperative hemodynamic stabilization are important first steps to minimize this complication.

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.

The application of mesh-reinforced hiatal closure has resulted in a significant reduction in recurrence rates in comparison with primary suture repair. One of the most debated issues is the risk of complications related to the use of the prosthesis, such as esophageal erosion and postoperative dysphagia. The aim of this study is to present our short-terms results in the treatment of laparoscopic paraesophageal hiatal hernia (LPHH) with a synthetic polyglycolic acid:trimethylene carbonate mesh (Gore Bio A(®)). From January 2011 to December 2012, 10 patients with large paraesophageal hiatal hernias and hiatal defect over 5 cm were included. Primary simple suture of the crura and additional reinforcement with a Gore Bio A(®) mesh was performed. Hiatal hernia or gastroesophageal reflux disease (GERD) symptoms recurrence, dysphagia and mesh-related complications were investigated. Of the 10 patients undergoing mesh repair, there were 7 women and 3 men with a mean age of 65.5 years. All operations were completed laparoscopically. Median postoperative stay was 3 days. After a median follow-up of 20.3 months, one patient developed a recurrent hiatal hernia (10%). There were no mesh-related complications. The use of Gore Bio A(®) mesh for the laparoscopic repair of large paraesophageal hiatal hernias is safe and with a reasonably low recurrence rate in this short-term study. Additional long-term studies with ample numbers carried out for years will be necessary to see if this synthetic mesh is not only safe but also successful in the prevention of recurrences.

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.

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.

Ventral hernia repair (VHR) is a commonly performed surgical procedure. Unfortunately, long-term prospective information about quality of life and outcomes after VHR has been challenging to obtain. Decoupling follow-up from clinical visits via patient-reported outcomes (PROs) has been proposed as a means of achieving better long-term assessments after VHR. The Americas Hernia Society Quality Collaborative (AHSQC) is a national quality improvement (QI) effort in hernia repair that uses PROs to obtain long-term follow-up. However, the modality of PRO engagement to maximize participation has not been well established. A formal QI initiative was undertaken to determine if long-term PRO follow-up could be increased at a single AHSQC site by adding telephone communication to email communication for long-term postoperative VHR assessment. Between September 2015 and July 2016, the long-term (greater than 1 year) AHSQC PRO completion rates after VHR at our institution were analyzed using plan-do-study-act cycles. Two interventions were implemented: contacting patients by telephone and changing timing of telephone calls. Two hundred thirty-two patients were identified, of whom 99 (42.7%) met eligibility criteria. Before this initiative, the long-term PRO completion rate was 16.3% in postoperative VHR patients. The completion rate after introducing telephone calls (intervention 1) was 35.7% and after changing the timing of telephone calls (intervention 2), was 55.1%. The mean participation rate was 45.4% (± 9.7%). A telephone-based approach markedly improved long-term PRO participation rates in postoperative VHR patients. Ultimately, a combination of email and telephone communication may be necessary to achieve higher levels of PRO follow-up in the VHR population. Copyright © 2016 American College of Surgeons.

The aim of this study was to demonstrate the safety and the efficacy of the self-gripping Parietex ProGrip™ mesh (Sofradim Production, Trévoux, France) used with the laparoscopic approach for inguinal hernia repair. The incidence of chronic pain, post-operative complications, patient satisfaction and hernia recurrence at follow-up after 12 months was evaluated. Data were collected retrospectively from patient files and were analyzed for 169 male and female patients with 220 primary inguinal hernias. All patients included had undergone surgical repair for inguinal hernia by the laparoscopic transabdominal preperitoneal approach using Parietex ProGrip™ meshes performed in the same clinical center in Germany. Pre-, per- and post-operative data were collected, and a follow-up after 12 months was performed prospectively. Complications, pain scored on a 0-10 numeric rating scale (NRS), patient satisfaction and hernia recurrence were assessed. The only complications were minor and were post-operative: hematoma/seroma (3 cases), secondary hemorrhage through the trocar's site (2 cases), hematuria, emphysema in the inguinal regions (both sides) and swelling above the genital organs (1 case for each). At mean follow-up at 22.8 months, there were only 3 reports of hernia recurrence: 1.4 % of the hernias. Most patients (95.9 %) were satisfied or very satisfied with their hernia repair with only 1.2 % reporting severe pain (NRS score 7-10) and 3.6 % reported mild pain. This study demonstrates that in experienced hands, inguinal hernia repair surgery performed by laparoscopic transabdominal preperitoneal hernioplasty using Parietex ProGrip™ self-gripping meshes is rapid, efficient and safe with low pain and low hernia recurrence rate.

Traumatic abdominal wall hernia (TAWH) is defined as herniation through a disrupted portion of musculature/fascia without skin penetration or history of prior hernia. In children, TAWH is a rare injury. The objectives of this study were to report our experience with different management strategies of TAWH in children and to determine the utility of laparoscopy. A retrospective chart review of all children treated by pediatric surgery at our institution for TAWH in a 5year interval was performed. Data were collected on mechanism of injury, initial patient presentation, surgical management, and outcomes. We present 5 cases of traumatic abdominal wall hernia; 3 were managed using laparoscopic assistance. One patient was managed nonoperatively. All patients recovered without complications and were asymptomatic on follow up. Traumatic abdominal wall hernias require a high index of suspicion in the cases of blunt abdominal trauma. Laparoscopy is useful mainly as a diagnostic modality, both to evaluate the hernia and associated injuries to intraabdominal structures. Its use may facilitate repair through a smaller incision. Conservative management of TAWH may be appropriate in select cases where there is a low risk of bowel strangulation. Copyright © 2015 Elsevier Inc. All rights reserved.

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 aim of the present study was to describe and assess a new method of fixation using a self-adhesive prosthesis (Adhesix(™)) in laparoscopic ventral rectopexy (LVR). The technical principles are based on a very low dissection and the adhesive properties of the prosthesis which can be applied to the rectum without stitches or staples. The prosthesis is made from polypropylene coated with a synthetic hydrogel. The binding of the prosthesis to rectum and vagina takes place in a wet environment after a few minutes and enables the shaping of the mesh on the surface of the rectum (wrap effect). Between March 2010 and March 2013, 41 patients were operated on using LVR with a self-adhesive prosthesis. The effectiveness of prosthesis fixation was evaluated in a subset of 27 patients suffering from complete rectal prolapse. With a median follow-up of 30 months, there were no major complications and no recurrence. In this initial experience, LVR with a self-adhesive prosthesis does not increase the risk of recurrence. No undesirable effects were associated with the prosthesis.

For this study, 66 patients with a preoperative diagnosis of unilateral primary inguinal hernia were randomized to undergo laparoscopic totally extra peritoneal (TEP), laparoscopic transabdominal (TAPP), or open inguinal hernia repair with polypropylene mesh (Lichtenstein type). Both the operative team caring for the patient postoperatively and the patient were blinded to the operative approach by placement of a large dressing covering the abdomen, which was not removed until postoperative day 3. The patients recorded their pain level on a visual analog pain scale daily. Medication usage also was recorded. All patients were seen at 7-day intervals until they returned to work. The patients were interviewed during their postoperative visits by an investigator blinded to the operative approach and questioned regarding their ability to return to work and their pain levels. The average number of lost work days in all the groups was 12, and there was no significant difference between the three groups (p = 0.074). The average operating time for the TAPP procedure was 59 min, less than the time required to complete either the TEP or the Lichtenstein approach, which had equivalent operative times (p = 0.027). The material cost was significantly lower for the Lichtenstein repair (1,200 dollars less) than for either of the laparoscopic approaches, a saving primarily related to consumable operating room supplies. The TEP repair costs were minimally higher than those for the TAPP repair (125 dollars more). No significant differences were noted in the postoperative pain scales, and the use of postoperative oral analgesics was equivalent. The higher operative costs noted for the laparoscopic hernia repairs were not offset by a shortened convalescence. Postoperative pain appears to be equivalent regardless of the operative approach chosen and is easily managed with oral analgesics.

The surgical repair of inguinal hernia and hydrocele is one of the most common operations performed in pediatric surgery practice. This article reviews current concepts in the management of inguinal hernia and hydrocele based on the recent literature and the authors׳ experience. We describe the principles of clinical assessment and anesthetic management of children undergoing repair of inguinal hernia, underlining the differences between an inguinal approach and minimally invasive surgery (MIS). Other points discussed include the current management of particular aspects of these pathologies such as bilateral hernias; contralateral patency of the peritoneal processus vaginalis; hernias in premature infants; direct, femoral, and other rare hernias; and the management of incarcerated or recurrent hernias. In addition, the authors discuss the role of laparoscopy in the surgical treatment of an inguinal hernia and hydrocele, emphasizing that the current use of MIS in pediatric patients has completely changed the management of pediatric inguinal hernias.

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

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

Previous work demonstrated that prior MRSA infection [MRSA(+)] is associated with 30-day surgical site infection (SSI) following ventral hernia repair (VHR). We aimed to determine the impact of MRSA(+) on long-term wound outcomes after VHR. A retrospective cohort study was performed at a tertiary center between July 11, 2005, and May 18, 2012, of patients undergoing elective VHR with class I wounds. Patients with documented preoperative MRSA infection at any site (urinary, bloodstream, SSI, etc.) were considered MRSA(+). Primary outcome was 2-year surgical site occurrence (SSO), defined as SSI, cellulitis, necrosis, nonhealing wound, seroma, hematoma, dehiscence, or fistula. SSOs were subdivided into those that required procedural intervention (SSOPI) and those that did not. Among 632 patients, 46 % were female with average age 53 ± 13 years. There were 368 SSOs in 193 patients (31 %); an SSOPI occurred in 9.8 % (n = 62). The most common SSOs were cellulitis (91/632), seroma (91/632), and serous drainage (58/632). The rate of 2-year SSO was higher with MRSA(+) compared to those without (46 vs. 29 %, p = 0.023), attributed to increased soft tissue necrosis, purulent drainage, serous drainage, cellulitis, and fistula. In multivariable analysis, MRSA(+) was not associated with 2-year SSO (HR 1.5, 95 % CI 0.91-2.55, p = 0.113); factors associated with SSO included obesity, immunosuppression, mesh repair, and operative times. This study is the first to evaluate long-term SSOs and SSOPIs after VHR, highlighting the importance of long-term follow-up. Though not independently associated with SSOs, MRSA(+) may be a marker of hernia complexity.

The medical complexity of hernia patients imparts higher risk for complications, and mortality is a distinct reality. No study has stratified patients based on preoperative risk for open ventral hernia repair (VHR) specifically. We utilized the American College of Surgeons National Surgical Quality Improvement Program to create a mortality risk stratification model following VHR. Patients undergoing open VHR were identified from American College of Surgeons National Surgical Quality Improvement Program databases. Baseline variables correlated with mortality risk were entered into stepwise regression and bootstrap analysis. β-Coefficients were used to weigh each factor, yielding the risk assessment tool. A total of 55,760 patients were included with a mortality of 1.34%. Predictors of mortality included the following: functional status (odds ratio [OR] = 2.87), liver disease (OR = 3.61), malnutrition (OR = 1.43), age greater than 65 years (OR = 2.39), American Society of Anesthesiologists 4 or higher (OR = 2.90), systemic inflammation (OR = 1.99), and contamination (OR = 2.15). Patients were risk stratified into low risk (mortality .33%), moderate risk (mortality 1.86%), high risk (mortality 8.76%), and extreme risk groups (mortality 34.2%). Unplanned reoperations and medical complications increased across risk groups. The model demonstrated high discriminatory ability with a C-statistic value of .86. This study provides an accurate model to predict mortality risk specific to open VHR. The strongest predictors were American Society of Anesthesiologists, liver disease, functional status, and older age. This tool may inform clinical decision making to reduce complications.

The retromuscular or sublay repair of ventral hernias, popularized by Rives and Stoppa, requires that a layer of tissue be reapproximated dorsal to the mesh to separate the bowel from the prosthetic. This is the first report of two patients who developed bowel obstruction resulting from interparietal incarceration between the posterior rectus sheath and the prosthetic graft through a defect in this dorsal layer. Both patients underwent open retromuscular hernia repair, one with lightweight polypropylene mesh, the other with human acellular dermal matrix. Postoperatively (day 3 and day 42, respectively), the patients developed signs of bowel obstruction. Computed tomography demonstrated the herniation of the small bowel into the potential space between the prosthesis and the posterior rectus sheath. The first patient underwent successful laparoscopic repair, while the second patient had an open operation to reduce the incarcerated bowel and repair the defect. In the patient convalescing from an uneventful retromuscular hernia repair who develops signs and symptoms of a bowel obstruction, there should be a high index of suspicion that an interparietal hernia may have formed, with the small bowel herniated into the surgically created space between the prosthetic and the posterior rectus sheath.

At the dawn of this new millennium, surgeons not only must be masters of their craft but also are responsible for identifying and learning new techniques that are being introduced at an ever-increasing rate. Surgeons must overcome the instinctual mistrust of "the new" and, at the same time, avoid over enthusiastic, uncritical adoption of unproven procedures. Today's surgeons must also carefully assess and select the procedures and technologies that they will have time to learn and that will complement their practices and interests. More new things are coming along than any single individual can learn and practice with expertise, which makes general surgery a specialty with relative, as opposed to specifically, defined boundaries. Surgeons also should participate in the process of measuring the outcomes effective and to offer some advantages over open repair, namely less pain and a more rapid recovery period. On the other hand, this surgery has been shown to be difficult to learn and more costly. In a situation such as this, one can delete the procedure from the individual or institutional repertoire or use the modern tools of medical management to attempt to address the "outlier" issues and preserve the good. Laparoscopic hernia repair is a good procedure that can be done in a cost-effective manner if cost-conscious practice guidelines are initiated. It is not yet, however, a technique for all surgeons because of its difficulty to learn and advanced skills needed to perform it well.

The aim of this study was to clarify the incidence of postoperative complications in infants undergoing laparoscopic hernia repair within the first six months of life. Retrospective, single-institution study comparing term and preterm babies undergoing surgery between March 2005 and September 2012. The charts were reviewed for postoperative complications and pre-existing diseases. In the term group 188 of 199 babies (94.5%) had an uneventful postoperative course. Eleven patients (5.5%) presented postoperative complications, three of them (1.5%) developed severe respiratory complications. A relation between pre-existing diseases and postoperative complications could be identified in two patients. Laparoscopy possibly induced cardiorespiratory instability in one infant. In the preterm group 109 of 137 babies (79.6%) had an uneventful postoperative course. 28 preterm infants (20.4%) developed postoperative complications, seven of them (5.1%) presented severe respiratory complications. Pre-existing diseases were identified as an influencing factor in 22 preterm infants. In one patient laparoscopy possibly caused minor instability of a pre-existing cardiac anomaly. Postoperative complications are low in both groups, although the incidence is increased in preterm infants. Pre-existing diseases are a major influencing factor for preterm infants. In very few infants laparoscopy may have induced instability of cardiac anomalies. © 2013.

Treatment of clean-contaminated and contaminated ventral hernia defects remains controversial. Newer prosthetic materials may play an important role in these patients. Ten patients with Ventral Hernia Working Group types 3 and 4 were prospectively enrolled and subsequently treated with direct supported repairs with condensed fenestrated polytetrafluoroethylene mesh. The primary outcome was hernia occurrence at 1 year after surgery. Secondary outcomes included surgical site infection, surgical site occurrence, medical complications, pain, and other patient-reported outcomes. There were no immediate postoperative infections and one minor postoperative hematoma treated in the office. One patient required delayed mesh removal 9 months after placement. Importantly, the mesh removal procedure was straightforward because of the material properties of the mesh. Of the 9 patients still with mesh, there were no hernia recurrences at the repair site with one full year of follow-up. Contaminated and clean-contaminated abdominal wall defects can be effectively and durably treated with condensed polytetrafluoroethylene mesh. Copyright © 2016 The Authors. Published by Elsevier Inc.

To describe patients developing grade III and IV hemorrhoids requiring surgery after laparoscopic ventral mesh rectopexy (LVMR) and to explore the relationship between developing such hemorrhoids and recurrence of rectal prolapse after LVMR. All consecutive patients receiving LVMR at the Meander Medical Centre, Amersfoort, the Netherlands, between 2004 and 2013 were analyzed. Kaplan-Meier estimates were calculated for recurrences. A total of 420 patients underwent LVMR. Sixty-five of these patients (actuarial 5-year incidence 24.3, 95 % confidence interval (CI) 18.6-30.0) developed symptomatic grade III/IV hemorrhoids requiring stapled or excisional hemorrhoidectomy. Re-do surgery for recurrent grade III/IV hemorrhoids was required for 15 of the 65 patients (actuarial 5-year recurrence rate 40.6, 95 % CI 23.2-58.0) after the primary hemorrhoidectomy. Three of the 65 patients developed an external rectal prolapse (ERP) recurrence and eight an internal rectal prolapse (IRP) recurrence. This generated a 5-year recurrence rate of 25.3 % (95 % CI 0-53.9) for ERP recurrence and 24.4 % (95 % CI 9.1-39.7) for IRP recurrence. The rest of the LVMR cohort not receiving additional surgery for hemorrhoids (n = 355) showed significantly lower actuarial 5-year ERP (0.8 %, p = 0.011) and IRP (11 %, p = 0.020) recurrence rates. High-grade hemorrhoids requiring surgery may be common after LVMR. The development of high-grade hemorrhoids after LVMR might be considered a predictor of rectal prolapse recurrence.

Introduction The purpose of this study is to compare the tissue incorporation of a novel fenestrated and non-fenestrated crosslinked porcine dermal matrix (CPDM) (CollaMend™, Davol Inc., Warwick, RI) in a porcine model of ventral hernia repair. Methods Bilateral abdominal wall defects were created in 12 Yucatan minipigs and repaired with a preperitoneal or intraperitoneal technique 21 days after hernia creation. Animals were randomized to fenestrated or non-fenestrated CPDM for n = 6 pieces of each graft in the preperitoneal or intraperitoneal location. All animals were sacrificed at 1 month. Adhesion characteristics and graft contraction/growth were measured by the Garrard adhesion grading scale and transparent grid overlay. Histological analysis of hematoxylin and eosin (H&E)-stained slides was performed to assess graft incorporation. Tissue incorporation strength was measured by a T-peel tensile test. The strength of explanted CPDM alone and de novo CPDM was measured by a uniaxial tensile test using a tensiometer (Instron, Norwood, MA) at a displacement rate of 0.42 mm/s. Statistical significance (P < 0.05) was determined for histological analysis using a Kruskal–Wallis non-parametric test with a Bonferroni correction, and for all other analyses using a two-way analysis of variance (ANOVA) with a Bonferroni post-test or a Kruskal–Wallis non-parametric test with a Dunn’s post-test. Results Intraperitoneal placement of fenestrated CPDM resulted in a significantly higher area of adhesions and adhesion score compared to the preperitoneal placement of fenestrated CPDM (P < 0.05). For both preperitoneal and intraperitoneal placement, histological findings demonstrated greater incorporation of the graft due to the fenestrations. No significant differences were detected in the uniaxial tensile strengths of the graft materials alone, either due to the graft type (non-fenestrated vs. fenestrated) or due to the placement location (preperitoneal vs. intraperitoneal

AIM: To analyze the outcomes of laparoscopic ventral mesh rectopexy in the management of complete rectal prolapse (CRP) in North Indian patients with inherent bulky and redundant colon. METHODS: The study was conducted at a tertiary health care center of North India. Between January 2010 and October 2014, 15 patients who underwent laparoscopic ventral mesh repair for CRP, were evaluated in the present study. Perioperative outcomes, improvement in bowel dysfunction or appearance of new complications were documented from the hospital records maintained prospectively. RESULTS: Fifteen patients (9 female) with a median age of 50 years (range, 15-68) were included in the study. The median operative time was 200 min (range, 180-350 min) and the median post-operative stay was 4 d (range, 3-21 d). No operative mortality occurred. One patient with inadvertent small bowel injury required laparotomy on post-operative day 2. At a median follow-up of 22 mo (range, 4-54 mo), no prolapse recurrence was reported. No mesh-related complication was encountered. Wexner constipation score improved significantly from the preoperative value of 17 (range, 5-24) to 6 (range, 0-23) (P < 0.001) and the fecal incontinence severity index score from 24 (range, 0-53) to 2 (range, 0-53) (P = 0.007). No de novo constipation or fecal incontinence was recorded during the follow-up. On personal conversation, all patients expressed satisfaction with the outcome of their treatment. CONCLUSION: Our experience indicates that laparoscopic ventral mesh rectopexy is an effective surgical option for CRP in North Indian patients having a bulky redundant colon. PMID:27152139

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.

Introduction Laparoscopic repair is becoming an increasingly popular alternative in the treatment of abdominal wall hernias. In spite of numerous studies evaluating this technique, indications for laparoscopic surgery have not been established. Similarly, implant selection and fixation techniques have not been unified and are the subject of scientific discussion. Aim To assess whether there is a consensus on the management of the most common ventral abdominal wall hernias among recognised experts. Material and methods Fourteen specialists representing the boards of European surgical societies were surveyed to determine their choice of surgical technique for nine typical primary ventral and incisional hernias. The access method, type of operation, mesh prosthesis and fixation method were evaluated. In addition to the laparoscopic procedures, the number of tackers and their arrangement were assessed. Results In none of the cases presented was a consensus of experts obtained. Laparoscopic and open techniques were used equally often. Especially in the group of large hernias, decisions on repair methods were characterised by high variability. The technique of laparoscopic mesh fixation was a subject of great variability in terms of both method selection and the numbers of tackers and sutures used. Conclusions Recognised experts have not reached a consensus on the management of abdominal wall hernias. Our survey results indicate the need for further research and the inclusion of large cohorts of patients in the dedicated registries to evaluate the results of different surgical methods, which would help in the development of treatment algorithms for surgical education in the future.

Background The aim of this prospective, randomized, single-blinded clinical trial was to compare the incidence of chronic pain after laparoscopic transabdominal preperitoneal hernia repair (TAPP) using a 35-g/m2 titanized polypropylene mesh and a 16-g/m2 titanized polypropylene mesh. The reported incidence of chronic pain in patients who underwent laparoscopic hernia repair is a serious problem. The techniques of dissection, mesh fixation, and the mesh material used have all been identified as being part of the problem. Excellent biocompatibility through a unique combination of a lightweight open porous polypropylene mesh covered with a covalent-bonded titanium layer has been claimed. The aim of this study was to find out whether the titanium surface alone or the difference in material load between the two available meshes influences clinical outcomes. Methods Three hundred eighty patients with 466 inguinal hernias were operated on between 2002 and 2006 with the laparoscopic transabdominal preperitoneal (TAPP) technique. Mesh fixation with staples was carried out routinely. After the dissection was completed just prior to the implantation of the mesh, patients were randomized into two groups. In Group A, 250 (53.6%) inguinal hernias were repaired with a 35-g/m2 titanized polypropylene mesh, and in Group B, 216 (46.4%) inguinal hernias were repaired with a 16-g/m2 titanized polypropylene mesh. The primary outcome was chronic pain 3 years after surgery. The degree of pain was determined using a visual analog scale (VAS) with a range from 0 to 10. The secondary outcome was the rate of recurrence. Results The postoperative period of observation was at least 3 years for every patient. In both groups, 90% of the patients could be questioned and examined clinically: in Group A (Light), 5.3% of the patients and in Group B (Extralight), 1.5% of the patients suffered from chronic pain. Chronic pain was significantly more common in Group A than in Group B (p = 0

Roux-en-Y gastric bypass (RYGBP) is currently the most common bariatric procedure. One of its late complications is the development of internal hernia, which can lead to acute intestinal obstruction or recurrent colicky abdominal pain. The aim of this paper is to present a new, unusual, and so far not reported type of internal hernia. A common computerized database is maintained for all patients undergoing bariatric surgery in our departments. The charts of patients with the diagnosis of internal hernia were reviewed. Three patients were identified who developed acute intestinal obstruction due to an internal hernia located between the jejunojejunostomy and the end of the biliopancreatic limb, directly between two jejunal limbs with no mesentery involved. Another seven patients with intermittent colicky abdominal pain, re-explored for the suspicion of internal hernia, were found to also have an open window of the same location apart from a hernia at one of the typical hernia sites. Since this gap is systematically closed during RYGBP, no other patient has been observed with this problem. Even very small defects can lead to the development of internal hernias after RYGBP. Patients with suggestive symptoms must be explored. Closure of the jejunojejunal defect with nonabsorbable sutures prevents the development of an internal hernia between the jejunal loops at the jejunojejunostomy.

Surgical energy has been widely implemented because of ease of use, effective hemostasis, and surgical dissection. Studies demonstrate its use to be an independent risk factor for postoperative wound infection. Methicillin-resistant Staphylococcus aureus (MRSA) is the most common bacteria found in postoperative mesh infection. No reports are available on the sequelae of surgical energy use for open ventral hernia repair (oVHR) with mesh. We hypothesized that increasing amounts of surgical energy will result in higher infectious burden after oVHR with composite multifilament polyester mesh (Parietex™ PCO). New Zealand rabbits underwent bridging oVHR with Parietex™ PCO and were divided into three surgical treatment groups: (1) scalpel alone, (2) 120 J of energy, and (3) 600 J of energy. The bioprosthesis was then inoculated with 10(5) colony-forming units of MRSA. Rabbits were survived for 7 days with daily physical examination. Complete blood count, basci metabolic panel, and blood cultures were performed on postoperative days one, four, and seven. Surviving rabbits were killed, and meshes explanted for MRSA colony counts. Rabbits receiving the most surgical energy developed signs and symptoms of severe sepsis and wound necrosis within 24 h. In comparison, rabbits receiving no surgical energy had significantly less MRSA recovered from explanted mesh, significantly less bacteremia, and fewer adhesions. Increased use of surgical energy promoted greater colonization, exaggerated septic response to bacterial contamination, and more severe adhesions. In the absence of devitalized tissue, rabbits can effectively limit bacterial contamination. These findings support the surgical principles of proper tissue handling and highlight the detrimental effects of indiscriminant surgical energy usage, thus emphasizing the importance of programs such as Fundamental Use of Surgical Energy.

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

Single-port endoscopic-assisted percutaneous extraperitoneal closure of inguinal hernia with variable devices is a novel technique in minimal-access surgery for pediatric inguinal hernias. However, a small peritoneal gap of the suture at the location of spermatic vessels and vas deferens may be left untouched, whereas some subcutaneous tissues, including nerves and muscles, may cause injury by their inclusion in the upper portion of the circuit suturing. The technique may fail to entirely enclose the hernia defect and has the potential to lead to higher incidence of hydrocele and hernia recurrence. The authors describe the modification of single-port endoscopic-assisted ligation with a homemade hooked injection needle, which is designed to cause hydrodissection to the preperitoneal space, tautly enclose the hernia defect without upper subcutaneous tissues and a lower peritoneal gap, and aid in the achievement of a near-zero recurrence rate.

only recurrent inguinal hernia repair was associated with secondary ventral hernia surgery. In a cohort of 305 patients followed up a median of 3.7 years after emergency or elective laparotomy, a total of 79 patients were identified with an incisional hernia. Patients were subgrouped based on the identified risk factors male gender and smoking in eight groups with nine patients in each. Pooled serum samples were screened for MMP-1, MMP-2, MMP-3, MMP-7, MMP-8, MMP-9, MMP-10, MMP-12, MMP-13, TIMP-1, TIMP-2, and TIMP-4 with a multiarray and zymography. The screening indicated differences in MMP-9 and TIMP-1, which were measured in serum samples of the whole patient cohort with ELISA. There were no differences in systemic MMP-9 and TIMP-1 levels between patients with and without incisional hernia. Patients were enrolled consecutively in four groups: 1) patients undergoing elective laparoscopic cholecystectomy without hernias (N = 18), patients operated on for 2) primary unilateral inguinal hernia (N = 17), 3) multiple hernias defined as three or more primary hernias (N = 21) and 4) incisional hernia (N = 25). Venous blood was collected preoperatively. Pro-MMP-2 and pro-MMP-9 were measured in serum by gelatine zymography, and there were no significant differences between hernia patients and controls. Furthermore, serological biomarkers for type I, III, IV and V collagen turnover were measured in serum by solid-phase competitive immunoassays. In patients with inguinal hernia, type III and V collagen turnover were significantly decreased, whereas type IV collagen turnover was significantly increased. In incisional hernia patients, type V collagen turnover was significantly decreased, whereas type IV collagen turnover was significantly increased. Type IV collagen turnover seem to predict the presence of both inguinal and incisional hernia. An ePTFE tube was implanted perioperatively in all four patient groups and explanted on the tenth post-operative day. Newly synthesized

Indirect inguinal hernias are the most commonly incarcerated hernias in children, with a higher incidence in low birth weight and premature infants. Contralateral groin exploration to evaluate for a patent processus vaginalis or subclinical hernia is controversial, given that most never progress to clinical hernias. Most indirect inguinal hernias can be reduced nonoperatively. It is recommended to repair them in a timely fashion, even in premature infants. Laparoscopic repair of incarcerated inguinal hernia repair is considered a safe and effective alternative to conventional open herniorrhaphy. Other incarcerated pediatric hernias are extremely rare and may be managed effectively with laparoscopy. Copyright Â© 2016 Elsevier Inc. All rights reserved.

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. 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. Patients with a contaminated or clean-contaminated operative field and a hernia defect at least 9 cm 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. Patients had a mean age of 58 years, body mass index of 28 kg/m, 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). 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.

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.

In recent years, laparoscopic repair of abdominal wall hernias has become increasingly established in routine clinical practice thanks to the myriad advantages it confers. Apart from the risk of intestinal damage following adhesiolysis, to date no information is available on the best way of preventing the formation of new adhesions in the vicinity of the implanted meshes. Numerous experimental investigations, mainly conducted on an open small-animal model, have demonstrated the advantages of coating meshes, inter alia with absorbable materials, compared with uncoated polypropylene meshes. In our established laparoscopic porcine model we set about investigating three of these meshes, which are already available on the market. In total, 18 domestic pigs underwent laparoscopic surgery and three different composite meshes were tested in each case on six animals (Dynamesh IPOM, Proceed, Parietene Composite). At 4 months, postmortem diagnostic laparoscopy was carried out, followed by full-wall excision of the specimens. Planimetric analysis was conducted to investigate the size of the entire surface area and the extent of adhesions. Histological investigations were performed on five sections for each specimen. These focused on the partial volumes of inflammatory cells, the proliferation marker Ki67, apoptotic index, inflammatory cell marker CD68 and transforming growth factor beta (TGF-beta) as a marker of the extracellular matrix. A similar value of 14% was obtained for shrinkage of Dynamesh IPOM and Parietene Composite, while Proceed showed a 25% reduction in its surface area. Markedly lower values of 12.8% were obtained for Parietene Composite in respect of adhesions to the greater omentum, compared with 31.7% for Proceed and 33.2% for Dynamesh IPOM (p = 0.01). Overall, Parietene Composite performed best in the histological and immunhistochemistry tests. On the whole, all composite meshes showed evidence of good biocompatibility. However, none of the coatings was

Laparotomy is the standard approach for the surgical treatment of acute small bowel obstruction (ASBO). From February 2007 to May 2012 we prospectively recorded all patients operated by laparoscopy in our hospital because of ASBO due to adhesions (27 cases) and/or internal hernia (6 cases). A preoperative abdominal CT was performed in all cases. Patients suffering from peritonitis and/or sepsis were excluded from the laparoscopic approach. It was decided to convert to laparotomy if intestinal resection was required. The mean age of the 33 patients who underwent surgery was 61.1 ± 17.6 years. 64% had previous history of abdominal surgery. 72% of the cases were operated by surgeons highly skilled in laparoscopy. Conversion rate was 21%. Operative time and postoperative length of stay were 83 ± 44 min. and 7.8 ± 11.2 days, respectively. Operative time (72 ± 30 vs 123 ± 63 min.), tolerance to oral intake (1.8 ± 0.9 vs 5.7 ± 3.3 days) and length of postoperative stay (4.7 ± 2.5 vs 19.4 ± 21 days) were significantly lower in the laparoscopy group compared with the conversion group, although converted patients had greater clinical severity (2 bowel resections). There were two severe complications (Clavien-Dindo III and V) in the conversion group. In selected cases of ASBO caused by adhesions and internal hernias and when performed by surgeons highly skilled in laparoscopy, a laparoscopic approach has a high probability of success (low conversion rate, short hospital length of stay and low morbidity); its use would be fully justified in these cases.

Single-port laparoscopic cholecystectomy (SLC) requires a larger initial umbilical incision than conventional multiport laparoscopic cholecystectomy (MLC). In this retrospective analysis study we compared the demographics, clinical data, and incidence of postoperative trocar site hernias (TSH) in patients undergoing SLC with those in patients undergoing MLC. A total of 161 patients were included in this study. Of these patients, 104 underwent MLC, 57 SLC. Patients in the MLC group were operated on using the four-trocar technique, patients in the SLC-port group using a fully reusable multi-trocar port system (X-Cone™). The earliest follow-up point was 12 months, the average follow-up period was 16.4 months (range 12-24 mos). The follow-up examinations for all patients consisted of a review of their medical history, a thorough physical examination, and an ultrasound examination of all existing trocar site scars. Patients in the SLC group had a lower mean American Society of Anesthesiologists score and a lower mean body mass index compared to patients in the MLC group. The average operating time was shorter for the patients in the SLC group, but the difference was not statistically significant. Ten (9.6%) patients in the MLC group and 3 (5.3%) in the SLC group developed a TSH (p = .55). At midterm follow-up the incidence of umbilical incisional hernias was not greater for SLC compared to MLC. The incidence of TSH after MLC was significantly higher than expected.

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.

To investigate whether operative factors are associated with risk of surgical site infection (SSI) after hernia repair. Retrospective cohort study. Patients Commercially insured enrollees aged 6 months-64 years with International Classification of Diseases, Ninth Revision, Clinical Modification procedure or Current Procedural Terminology, fourth edition, codes for inguinal/femoral, umbilical, and incisional/ventral hernia repair procedures from January 1, 2004, through December 31, 2010. SSIs within 90 days after hernia repair were identified by diagnosis codes. The χ2 and Fisher exact tests were used to compare SSI incidence by operative factors. A total of 119,973 hernia repair procedures were analyzed. The incidence of SSI differed significantly by anatomic site, with rates of 0.45% (352/77,666) for inguinal/femoral, 1.16% (288/24,917) for umbilical, and 4.11% (715/17,390) for incisional/ventral hernia repair. Within anatomic sites, the incidence of SSI was significantly higher for open versus laparoscopic inguinal/femoral (0.48% [295/61,142] vs 0.34% [57/16,524], P=.020) and incisional/ventral (4.20% [701/16,699] vs 2.03% [14/691], P=.005) hernia repairs. The rate of SSI was higher following procedures with bowel obstruction/necrosis than procedures without obstruction/necrosis for open inguinal/femoral (0.89% [48/5,422] vs 0.44% [247/55,720], P<.001) and umbilical (1.57% [131/8,355] vs 0.95% [157/16,562], P<.001), but not incisional/ventral hernia repair (4.01% [224/5,585] vs 4.16% [491/11,805], P=.645). The incidence of SSI was highest after open procedures, incisional/ventral repairs, and hernia repairs with bowel obstruction/necrosis. Stratification of hernia repair SSI rates by some operative factors may facilitate accurate comparison of SSI rates between facilities.

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

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.
The Aim of the Study is to Analyze the Incidence of Trocar Site Hernia (TSH); in Orifices Created by Trocars Measuring ≥10 mm in Diameter,; and to Determine Whether Closure of the External Fascial Layer Prevents; TSH and Potential Related Complications.
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.

Proper mesh fixation is critical for successful TAPP laparoscopic hernia repair. Conventional mesh fixation may cause chronic neuralgia, groin paresthesia or other complications. This study aimed at introducing a new vacuum suction technique for mesh fixation and evaluating its efficacy and safety compared with traditional staple fixation way. Clinical data of 242 patients undergoing TAPP from July 2011 to March 2014 were retrospectively analyzed. Patients were divided into vacuum suction fixation group and staple fixation group. The operation time, hospital stay, complications, recurrence, visual analogue scale pain score and cost were evaluated. All surgeries were successful. The operation time of staple group was (42.34 ± 10.15) min for unilateral hernia and (64.08 ± 16.01) min for bilateral hernias. The postoperative hospital stay was (2.76 ± 0.84) days. One recurrence was observed (0.90%). For vacuum group, the operation time was (42.66 ± 7.76) min and (63.92 ± 10.49) min, and hospital stay was (2.60 ± 0.74) days. No recurrence was observed. There was no significant difference in recurrence, operation time, postoperative pain and hospital stay between two groups (P > 0.05). Average cost were (11,714 ± 726) RMB for vacuum group which was lower than staple group (14,837 ± 1568) RMB (P < 0.05). The top three complications of staple group were scrotal emphysema (10.81%), scrotal seroma (6.31%) and temporary nerve paresthesia (4.50%) while for vacuum group, they were scrotal seroma (3.82%), temporary nerve paresthesia (3.05%), scrotal emphysema (1.53%) and uroschesis (1.53%). The incidence of scrotal emphysema was lower in vacuum group (P < 0.05). No significant difference was observed in other complications (P > 0.05). Both techniques for mesh fixation are safe and effective. There is no significant difference in recurrence, operation time, postoperative pain or hospital stay. The vacuum suction fixation technique is more economical with lower incidence of

The effect of laparoscopic sleeve gastrectomy (LSG) on gastroesophageal reflux disease (GERD) is controversial. Although concomitant hiatal hernia repair (HHR) at the time of LSG is common and advocated by many, there are few data on the outcomes of GERD symptoms in these patients. The aim of this study was to evaluate the effect of concomitant HHR on GERD symptoms in morbidly obese patients undergoing LSG. A single institution, multi-surgeon, prospectively maintained database was examined to identify patients who underwent LSG and concomitant HHR from December 2010 to October 2013. Patient characteristics, operative details, and postoperative outcomes were analyzed. Standardized patient questionnaires administered both pre- and postoperatively were utilized. Primary endpoints included subjective reflux symptoms and the need for antisecretory therapy. Weight loss was considered a secondary endpoint. Fifty-eight patients were identified meeting inclusion criteria (LSG + HHR), with a mean follow-up of 97.5 weeks (range 44-172 weeks). The mean age of the cohort was 49.5 ± 11.2 years, with 74.1 % being female. Mean preoperative BMI was 44.2 ± 6.6 kg/m(2). Preoperative upper gastrointestinal contrast series was performed in all patients and demonstrated a hiatal hernia in 34.5 % of patients and reflux in 15.5 % of patients. Preoperatively, 44.8 % (n = 26) of patients reported subjective symptoms of reflux and/or required daily antisecretory therapy [Corrected]. After LSG + HHR, 34.6 % of symptomatic patients had resolution of their symptoms off therapy while the rest remained symptomatic and required daily antisecretory therapy; 84.4 % of patients that were asymptomatic preoperatively remained asymptomatic after surgery. New onset reflux symptoms requiring daily antisecretory therapy was seen in 15.6 % of patients who were previously asymptomatic. Post surgical weight loss did not correlate with the presence or resolution of reflux symptoms. Based

The aim of this study was to assess the reduction in the incidence of parastomal hernia (PH) after placement of prophylactic synthetic mesh using a modified Sugarbaker technique when a permanent end-colostomy is needed. Prevention of PH formation is crucial given the high prevalence of PH and difficulties in the surgical repair of PH. A randomized, prospective, double-blind, and controlled trial. Rectal cancer patients undergoing laparoscopic abdominoperineal resection with permanent colostomy were randomized (1 : 1) to the mesh and nonmesh arms. In the mesh group, a large-pore lightweight composite mesh was placed in the intraperitoneal/onlay fashion using a modified Sugarbaker technique. PH was detected by computed tomography (CT) after a minimum follow-up of 12 months. Analysis was per-protocol. The mesh group included 24 patients and the control group 28. Preoperative data, surgical time, and postoperative morbidity were similar. The median follow-up was 26 months. After CT examination, 6 of 24 PHs (25%) were observed in the mesh group compared with 18 of 28 (64.3%) in the nonmesh group (odds ratio 0.39, 95% confidence interval 0.18-0.82; P = 0.005). The Kaplan-Meier curves showed significant differences in favor of the mesh group (long-rank = 4.21, P = 0.04). The number needed to treat was 2.5, which confirmed the effectiveness of the intervention. Placement of a prosthetic mesh by the laparoscopic approach following the modified Sugarbaker technique is safe and effective in the prevention of PH, reducing significantly the incidence of PH.

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

It was analyzed the results of clinical and ultrasound examination of the abdominal wall in 180 patients with different surgical diseases of the abdominal cavity. All patients were divided into 3 groups of 60 persons on the basis of the preoperative examination results. The first group included patients without clinical and ultrasound disorders, the second and the third - with mild and severe anatomical and functional failure of the abdominal wall. 20% of patients from the first group had single strain of the abdominal wall after operation without the development of postoperative hernias. 3.3% of patients in the second group had defects and 15% of patient from the same group had severe thinning of the abdominal wall. 45% of patients in the third group had postoperative hernias. Relative and absolute indications for preventive replacement of the abdominal wall were defined.

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

The incidence of incisional hernia(IH) may be affected by the choice of specimen extraction incision. The objective of this study was to perform a systematic review and meta-analysis comparing the incidence of IH after midline and off-midline incisions in patients undergoing laparoscopic colorectal surgery. A systematic search was performed according to PRISMA guidelines to identify all comparative studies from January 1991-August 2016 on the incidence of IH after midline and off-midline(transverse or Pfannenstiel) incisions in patients undergoing laparoscopic colorectal surgery. Case series and studies reporting the IH after stoma site extraction, SILS, or NOTES were excluded. The MINORS instrument was used for quality assessment for observational studies. Weighted estimates were calculated using a random-effects model. A total of 17 articles were identified and included for meta-analysis, 16 of which were observational studies and 1 was an RCT. The mean MINORS score for observational studies was 12.9 (SD 3.2, range 7-17). Sample sizes in the midline (mean 185, range 20-995) and off-midline(mean 184, range 20-903) groups were similar. Follow-up ranged from 17.3 to 42 months. The pooled incidence of IH was 10.6% (338/3177) in midline, 3.7% (48/1314) in transverse, and 0.9% (9/956) in Pfannenstiel incisions. IH was significantly higher in the midline compared to off-midline groups (weighted OR 4.1, 95% CI 2.0-8.3, I (2) = 79.7%, p for heterogeneity <0.001). Midline incisions were also at higher risk of IH versus transverse (weighted OR 3.0, 95% CI 1.4-6.7, I (2) = 72.7%, p for heterogeneity <0.001) and Pfannenstiel (weighted OR 8.6, 95% CI 3.0-24.6, I (2) = 43.5%, p for heterogeneity = 0.101) incisions. There was no publication bias according the funnel plot or statistically (Egger's p = 0.336). Midline incisions for specimen extraction in laparoscopic colorectal surgery are at significantly higher risk of IH compared to off-midline (transverse or

Reduced postoperative pain is considered one of the benefits of laparoscopic inguinal hernia repair (LHR). We investigated the need for intravenous flurbiprofen axetil (FA) before emergence from anesthesia in patients who had undergone LHR. Forty adult patients who were prepared for LHR were randomly divided into the FA group (FA 1 mg x kg(-1) administered at the end of surgery, n = 20) and the control group (no FA administration, n = 20). Postoperative pain was evaluated by the Prince Henry Pain Score (PHPS) as well as by the frequency of on-demand use of nonsteroidal antiinflammatory drugs (NSAIDs). The PHPS on arrival at the ward was significantly lower in the FA group than the control group. Additionally, none of the patients of the FA group required NSAIDs in the first two hours of postoperative period, compared with 6 patients (30%) of the control group. However, at 4 hours postoperatively, none of the patients of both groups suffered pain at rest and the PHPS was similar in the two groups. Although postoperative pain after LHR is mild and disappears rapidly, FA administration before emergence from anesthesia is necessary for management of pain during the immediate postoperative period.

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

Laparoscopic techniques currently constitute an alternative proposed for the repair of hernias of the inguinofemoral region. Nerve injuries have led some teams to recommend technical principles based on the anatomical relations of these nerves with the subperitoneal fascia transversalis and inguinal fossae. An anatomical study consisting of dissection of nonembalmed cadavres, allowed, after evisceration, dissection of the lumbar plexus and its terminal branches, particularly those supplying the inguinofemoral region: iliohypogastric and ilio-inguinal nerves, the genitofemoral nerve, the femoral nerve and the lateral cutaneous nerve of the thigh. Via transperitoneal laparoscopy, the posterior surface of the anterior abdominal wall is centered on the deep inguinal ring, containing testicular vessels and the vas deferens. This deep inguinal ring receives the genitofemoral nerve. Medially, the anterior parietal peritoneum describes three folds formed by the outline of the epigastric artery, umbilical artery and urachus on the midline. The outline of Hesselbach's ligament separates the deep inguinal ring from Hesselbach's triangle, the zone of weakness of direct inguinal hernia. The iliac psoas muscle pass laterally underneath the inguinal ligament, while the external iliac vessels, subsequently becoming the femoral vessels, are located medially. Pectineal ligament lies on the posterior surface of the femoral ring between the umbilical artery and the epigastric artery. Installation of an abdominal wall prosthesis, either transperitoneally or retroperitoneally, must be centered on the deep inguinal ring, and its solid sutures are located medially to the pectineal ligament and anterior abdominal wall. On the other hand, the nerves at risk of being damaged are situated laterally: the ilio-inguinal and ilio-hypogastric nerves in the plane between external oblique and internal oblique above the anterior superior iliac spine, lateral cutaneous nerve of the thigh under the

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

Mesh repair of large hiatal hernias has increasingly gained popularity to reduce recurrence rates. Integration of iron particles into the polyvinylidene fluoride mesh-based material allows for magnetic resonance visualisation (MR). In a pilot prospective case series eight patients underwent surgical repair of hiatal hernias repair with pre-shaped meshes, which were fixated with fibrin glue. An MR investigation with a qualified protocol was performed on postoperative day four and 3 months postoperatively to evaluate the correct position of the mesh by assessing mesh appearance and demarcation. The total MR-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. We documented no mesh migrations or dislocations but we found a significant decrease of MR-visualised total mesh surface area after release of the pneumoperitoneum compared to the original mesh size (mean 78.9 vs 84 cm(2); mean reduction of mesh area = 5.1 cm(2), p < 0.001). At 3 months postoperatively, a further reduction of the mesh surface area could be observed (mean 78.5 vs 78.9 cm(2); mean reduction of mesh area = 0.4 cm(2), p < 0.037). Detailed mesh depiction and accurate assessment of the surrounding anatomy could be successfully achieved in all cases. Fibrin glue seems to provide effective mesh fixation. In addition to a significant early postoperative decrease in effective mesh surface area a further reduction in size occurred within 3 months after implantation.

Background The laparoscopic ventral hernia repair technique made possible surgeries with smaller skin incisions and smaller dissection of the soft tissue around the hernia, therefore with a better wound, a quicker postoperative recovery and a lower complication rate. Aim To evaluate the applicability of a quality of life survey based on the molds of the American Hernia Society, European Hernia Society and Carolinas Equation for Quality of Life, through telephone in patients submitted to laparoscopic hernioplasty by IPOM technique. Methods A retrospective cohort study was made to evaluate the quality of life of 21 patients that underwent anterior abdominal wall laparoscopic hernioplasty by intraperitoneal onlay mesh technique. Questionnaire was applied through telephone. Results Of the 21 patients, 19% felt that the hernia recurred. Also 19% passed through another abdominal wall surgery, and among these, 75% was related to the previously hernia correction. Finally, 81% of patients did not undergo any other abdominal wall surgery. Conclusion It was possible to apply the quality of life questionnary by telephone on patients who underwent an anterior abdominal wall. The results, in its turn, were satisfactory and showed that patients, in general, were satisfied with the surgical procedure. PMID:24676295

With advancements in minimal access surgery, combined laparoscopic procedures are now being performed for treating coexisting abdominal pathologies at the same surgery. In our center, we performed 145 combined surgical procedures from January 1999 to December 2002. Of the 145 procedures, 130 were combined laparoscopic/endoscopic procedures and 15 were open procedures combined with endoscopic procedures. The combination included laparoscopic cholecystectomy, various hernia repairs, and gynecological procedures like hysterectomy, salpingectomy, ovarian cystectomy, tubal ligation, urological procedures, fundoplication, splenectomy, hemicolectomy, and cystogastrostomy. In the same period, 40 patients who had undergone laparoscopic cholecystectomy and 40 patients who had undergone ventral hernia repair were randomly selected for comparison of intraoperative outcomes with a combined procedure group. All the combined surgical procedures were performed successfully. The most common procedure was laparoscopic cholecystectomy with another endoscopic procedure in 129 patients. The mean operative time was 100 minutes (range 30-280 minutes). The longest time was taken for the patient who had undergone laparoscopic splenectomy with renal transplant (280 minutes). The mean hospital stay was 3.2 days (range 1-21 days). The pain experienced in the postoperative period measured on the visual analogue scale ranged from 2 to 5 with a mean of 3.1. Of 145 patients who underwent combined surgical procedures, 5 patients developed fever in the immediate postoperative period, 7 patients had port site hematoma, 5 patients developed wound sepsis, and 10 patients had urinary retention. As long as the basic surgical principles and indications for combined procedures are adhered to, more patients with concomitant pathologies can enjoy the benefit of minimal access surgery. Minimal access surgery is feasible and appears to have several advantages in simultaneous management of two different

We report the case of a 4-year-old girl treated by a laparoscopic transabdominal preperitoneal (TAPP) technique with polypropylene mesh in whom a primary contralateral hernia was found and repaired, closing the orifice with a suture. This 4-year-old female had a medical history of clubfoot treated by surgery during her first year of age, ureteral reimplantation because of stenosis, and laparoscopic cholecystectomy because of hydrocholecystis. She had recurrence 1 year after a conventional inguinal herniorraphy and was treated by the TAPP technique with polypropylene mesh. A primary contralateral hernia was found and repaired, and the orifice was closed with a suture. The child's acceptance of the procedure was good, and the postoperative evolution was uneventful, requiring minimal analgesia in the first 24 h. She was discharged the following day. Two years later, there have been no recurrences, and the girl is developing and carrying out activities in a normal way. The open technique remains the gold standard for hernioplasty in children, but laparoscopy may be an option, and it is possible that in some special cases, the use of mesh to reinforce the inguinal wall using the TAPP technique, although it is controversial, may be justified.

Background Laparoscopy is widely practiced and offers realistic benefits over conventional surgery. Port closure is important after a laparoscopic procedure to prevent port site incisional hernia. Larger port size and increasing numbers of ports needed to perform more complex laparoscopic procedures are likely to increase the incidence of port site hernias (PSHs). PSHs tend to develop more frequently at umbilical and midline port sites due to the thinness of the umbilical skin and weaknesses in the linea alba. More than 90% of PSHs occur through 10 mm and large ports can occur through 5 mm ports also. The aim was to study the outcomes and complications in laparoscopic surgery without fascial sheath closure of port site. We compared the results with another group in which fascial closure was done by a standard method. Methods This was a prospective study carried out in the Department of Surgery, MMIMSR, Mullana, Ambala, from August 2013 to 2015 in a single unit by a single surgeon. A total of 200 patients were selected randomly for the different laparoscopic procedures. Patients were divided into group A (only skin closure was done without fascia closure) and group B (fascial closure of the port in addition to skin closure). In both groups, we used blunt trocar for the 10 mm port. Skin of the 5 mm port was closed simply. The results in two groups were compared in terms of complications like PSH, bleeding, and wound infection. Results The outcomes in two groups were compared with and without fascia closure of 10 mm trocar port site. Patients operated for lap cholecystectomy were 170 (85%), 10 (5%) for lap appendicectomy, and 20 (10%) for lap hernia. The study compared the results in two groups mainly for PSH formation. The P value was insignificant and Fischer’s exact test result came as 1.00. There were no significant differences between the two groups in terms of PSH, bleeding and infection in non-obese cases. Conclusion In both groups, blunt trocar was

A Spigelian hernia (SH) is an acquired ventral hernia that most commonly occurs in the Spigelian belt. Patients may experience pain or a bulge in the abdominal area, but in most cases there are no symptoms. If left untreated the hernia may become strangulated, which could lead to bowel obstruction. We reviewed 28 surgical patients with SH between January 2002 and December 2013. We evaluated the incidence of complications, recurrences, and the length of hospital stay with comorbidities, body mass index, clinical presentation, and operative techniques. The 28 patients included 10 males and 18 females, with a mean age of 67 years. Seven patients (26.9%) received emergency operations, and the remaining patients received elective operations. An "open-direct" operative approach was used in 16 cases and a laparoscopic approach in 12. The overall complication rate was 7.6% and the recurrence rate was 3.8% with a median follow-up of 3 years. The median hospital stay was 1 day (range, 1-7). Only the presence of local complications at diagnosis showed a significant impact on length of hospital stay. None of the considered variables had a significant impact on hernia recurrence. No differences were noted among the operative techniques, wound infections, complications rate, and length of hospital stay. Laparoscopy seems to cause more early postoperative pain that reverses in about 2 weeks. Copyright © 2015 Elsevier Inc. All rights reserved.

Implant infection is a common clinical complication of abdominal hernia repair. Our objectives were to determine if acellular dermal matrix (ADM) grafts resisted Staphylococcus aureus infection better (as measured by ability to reduce or clear bacterial counts) than synthetic (polytetrafluoroethylene [PTFE]) mesh when used in abdominal wall reconstruction, and to determine whether vascularization of the implant occurred. We hypothesized that the ability of the ADM grafts to vascularize and allow cellular ingrowth would allow the immune system to clear the infection better in these animals. In New Zealand White rabbits (average weight, 3.0 kg), a full-thickness 3 x 3 cm(2) abdominal defect was created, then repaired with an interpositional implant (ADM, n = 62; PTFE, n = 57). Before skin closure, the epidermal surface of each implant was inoculated with 1 mL of S. aureus at various concentrations (10(4) colony-forming units [CFU]/mL, n = 82; 10(6) CFU/mL, n = 27; 10(9) CFU/mL, n = 10), and the rabbits were harvested at either day 7 or day 21. At day 7, ADM grafts inoculated with 10(4) CFU had lower counts or no bacteria (p = 0.006), fewer adhesions (p = 0.005), and fewer abscesses (p = 0.008) than PTFE grafts. By day 21, more ADM (n = 12) than PTFE (n = 0) grafts were free of bacteria (p = 0.002). Fewer rabbits with ADM grafts formed abscesses (13 vs. 19; p = 0.03). When evaluating the 7- and 21-day 10(4) CFU groups combined, a total of 15 rabbits with ADM cleared the bacteria completely vs. none of those with PTFE grafts (p < 0.001). There was no significant difference in bacterial counts or wound complications at days 7 or 21 between PTFE and ADM implants when inoculated with 10(6) CFU. All rabbits inoculated with 10(9) CFU died of sepsis within 48 h. Herniation did not occur in any of the animals. Our study demonstrates that ADM resists surgical site infection caused by S. aureus in an animal model without compromising the ventral hernia repair. This ability of

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 The aim of this study is to evaluate operating conditions during general anesthesia with or without neuromuscular blocker (NMB) in patients undergoing percutaneous internal ring suturing (PIRS). Materials and Methods In this study, 40 patients, with American Society of Anesthesiologists I and II between the ages of 1 and 12 years, were randomly assigned to two groups to receive muscle relaxant with endotracheal tube (ETT) (ETT group) or without muscle relaxant with supreme laryngeal mask airway (sLMA) (LMA group). Anesthesia was maintained with sevoflurane in oxygen (Fio 2 0.3-0.5), thiopental sodium, fentanyl, and rocuronium in ETT group. In LMA group, same protocol was used without rocuronium. Heart rate, blood pressure, peak airway pressure, end-tidal carbon dioxide (EtCO2), and Spo 2 were recorded before and during pneumoperitoneum maintained at a pressure of 8 to 10 mm Hg. Duration of surgery, recovery time, anesthetic time, and grade of quality view were also recorded. Airway problems (cough, hoarseness, laryngospasm, and aspiration) were recorded. Results In LMA group, there was a statistically significant reduction in recovery time versus ETT group (11.6 ± 4.08 vs. 17.15 ± 5.32 minutes; p = 0,001). There were no statistically significant differences grade of quality view between the two groups (p = 0.548). There were no statistically significant differences in oxygen saturation (Spo 2), peak airway pressure, and EtCO2 between the two groups before or during insufflation (p > 0.05). Postoperative airway complications were significantly more prevalent in the ETT group. There was no case of inadequate ventilation, regurgitation, or aspiration recorded. Conclusion sLMA is safe and suitable alternative to ETT and NMB is not necessary in general anesthesia with sLMA, pediatric patients undergoing laparoscopic hernia repair with PIRS.

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.

Purpose To evaluate the biocompatibility of heavyweight polypropylene (HWPP), lightweight polypropylene (LWPP), and monofilament knit polytetrafluoroethylene (mkPTFE) mesh by comparing biomechanics and histologic response at 1, 3, and 5 months in a porcine model of incisional hernia repair. Methods Bilateral full-thickness abdominal wall defects measuring 4 cm in length were created in 27 Yucatan minipigs. Twenty-one days after hernia creation, animals underwent bilateral preperitoneal ventral hernia repair with 8 × 10 cm pieces of mesh. Repairs were randomized to Bard®Mesh (HWPP, Bard/Davol, http://www.davol.com), ULTRAPRO® (LWPP, Ethicon, http://www.ethicon.com), and GORE®INFINIT Mesh (mkPTFE, Gore & Associates, http://www.gore.com). Nine animals were sacrificed at each timepoint (1, 3, and 5 months). At harvest, a 3 × 4 cm sample of mesh and incorporated tissue was taken from the center of the implant site and subjected to uniaxial tensile testing at a rate of 0.42 mm/s. The maximum force (N) and tensile strength (N/cm) were measured with a tensiometer, and stiffness (N/mm) was calculated from the slope of the force-versus-displacement curve. Adjacent sections of tissue were stained with hematoxylin and eosin (H&E) and analyzed for inflammation, fibrosis, and tissue ingrowth. Data are reported as mean ± SEM. Statistical significance (P < 0.05) was determined using a two-way ANOVA and Bonferroni post-test. Results No significant difference in maximum force was detected between meshes at any of the time points (P > 0.05 for all comparisons). However, for each mesh type, the maximum strength at 5 months was significantly lower than that at 1 month (P < 0.05). No significant difference in stiffness was detected between the mesh types or between timepoints (P > 0.05 for all comparisons). No significant differences with regard to inflammation, fibrosis, or tissue ingrowth were detected between mesh types at any time point (P > 0.09 for all comparisons). However

Objective The National Healthcare Safety Network does not risk adjust surgical site infection (SSI) rates after hernia repair by operative factors. We investigated whether operative factors are associated with risk of SSI after hernia repair. Design Retrospective cohort study. Patients Commercially-insured enrollees aged 6 months–64 years with ICD-9-CM procedure or CPT-4 codes for inguinal/femoral, umbilical, and incisional/ventral hernia repair procedures from 1/1/2004–12/31/2010. Methods SSIs within 90 days after hernia repair were identified by ICD-9-CM diagnosis codes. Chi-square and Fisher’s exact tests were used to compare SSI incidence by operative factors. Results A total of 119,973 hernia repair procedures were included in the analysis. The incidence of SSI differed significantly by anatomic site, with rates of 0.45% (352/77,666) for inguinal/femoral, 1.16% (288/24,917) for umbilical, and 4.11% (715/17,390) for incisional/ventral hernia repair. Within anatomic sites, the incidence of SSI was significantly higher for open versus laparoscopic inguinal/femoral (0.48% [295/61,142] versus 0.34% [57/16,524], p=0.020) and incisional/ventral (4.20% [701/16,699] versus 2.03% [14/691], p=0.005) hernia repairs. The rate of SSI was higher following procedures with bowel obstruction/necrosis than procedures without obstruction/necrosis for open inguinal/femoral (0.89% [48/5,422] versus 0.44% [247/55,720], p<0.001) and umbilical (1.57% [131/8,355] versus 0.95% [157/16,562], p<0.001), but not incisional/ventral hernia repair (4.01% [224/5,585] versus 4.16% [491/11,805], p=0.645). Conclusions The incidence of SSI was highest after open procedures, incisional/ventral repairs, and hernia repairs with bowel obstruction/necrosis. Our findings suggest that stratification of hernia repair SSI rates by some operative factors may be important to facilitate accurate comparison of SSI rates between facilities. PMID:25695175
Erosion of small intestine with necrotising fasciitis of over lying abdominal wall after expanded poly-tetrafluoroethylene mesh implantation: A rare complication after laparoscopic incisional hernia repair
Shrivastava, Ashish; Gupta, Akshara; Gupta, Achal; Shrivastava, Jyoti
Complications such as bowel erosions, enterocutaneous fistulae are rare with the use of expandedpoly-tetrafluoroethylene (ePTFE) mesh in laparoscopic incisional hernia repair (LIHR). This unusual case patient presented to us with necrotising fasciitis of overlying anterior abdominal wall with peritonitis withsepticaemia and underwent aLIHR6 weeks before, which has not been reported till yet. We report a case of LIHR, presented to us with necrotising fasciitis of overlying anterior abdominal wall, peritonitis and septicaemia which was managed by small bowel segmental resection and exteriorisation of the ends, debridement of overlying anterior abdominal wall and maximum resection of implanted mesh. This case is unusual secondary to long experience with ePTFE mesh and the lack of published cases similar to this one. A brief review of relevant literature has been included in the article. We recommend pre-peritoneal placement of dual mesh fixed preferably by trans-abdominal polypropylene suture in LIHR. PMID:24019695
External abdominal hernia occurs when abdominal organs or tissues leave their normal anatomic site and protrude outside the skin through the congenital or acquired weakness, defects or holes on the abdominal wall, including inguinal hernia, umbilical hernia, femoral hernia and so on. Acute incarcerated hernia is a common surgical emergency. With advances in minimally invasive devices and techniques, the diagnosis and treatment have witnessed major changes, such as the use of laparoscopic surgery in some cases to achieve minimally invasive treatment. However, strict adherence to the indications and contraindications is still required. PMID:25489584

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.
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

The usual approach in hernia surgery is to select the ideal repair method independent of the patient's characteristics. In the present study, we change the approach to ask which technique is best for the individual patient`s risk profile. For this, two criteria are important: does the patient need reconstruction of the abdominal wall? or does he or she need treatment of symptoms without being exposed to unnecessarily high perioperative risks? In a heuristic selection procedure, 486 consecutive patients were classified according to their characteristics as low-risk or high-risk for postoperative complications. Low-risk patients preferentially underwent open abdominal wall reconstruction with mesh (MFR + mesh), high-risk patients mainly a bridging-mesh procedure, either by laparoscopic (Lap.-IPOM) or open approach (Open-IPOM). Primary outcome was the incidence of postoperative complications. Secondary outcome was the recurrence-free interval. The propensity score was used for covariate adjustment analyzing recurrence rate as well as postoperative complications using Cox regression and logistic regression, respectively. Comparison of all surgical procedures showed risk factors had no independent influence on occurrence of complications (p = 0.110). Hernial gap width was an independent factor for occurrence of complications (p = 0.002). Propensity score adjustment revealed Lap.-IPOM to have a significantly higher recurrence rate than MFR + mesh (HR 2.367, 95% CI 1.123-4.957, p = 0.024). Three or more risk factors were protective against recurrence (HR 0.454, 95% CI 0.221-0.924, p = 0.030). In the univariate Cox regression analysis for recurrence, age >50 years was a protective prognostic factor (HR 0.412, 95% CI 0.245-0.702, p = 0.002). The classification criteria applied were internally validated. The heuristic algorithm ensured that patients at high-risk of complications did not have a higher perioperative complication rate than patients at low-risk.

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

Panniculectomy (PAN) during ventral hernia repair (VHR) can be a challenging procedure associated with added risk. We utilized the ACS-NSQIP datasets to generate a risk model of morbidity following these combined interventions. The 2005-2012 ACS-NSQIP databases were queried to identify all patients undergoing VHR-PAN. Multivariate logistic regression analyses were used to assess perioperative factors associated with surgical and medical morbidity. Internal validation was performed using bootstrap analysis and risk stratification was performed using weighted β-coefficients. 1974 patients underwent VHR-PAN with an average age of 53.6 ± 12.4 years and BMI of 36.4 ± 10.1 kg/m2. Surgical complications occurred in 23.8% of patients, whereas medical complications occurred in 11.5%. A multivariate logistic regression identified the presence of a renal comorbidity (OR = 1.62, P = 0.045), class II obesity (BMI = 34.9-40.0 kg/m2) (OR = 1.89, P < 0.001), class III obesity (BMI≥40 kg/m2) (OR = 2.66, P < 0.001), dirty/infected wound class (OR = 2.01, P = 0.003), smoking (OR = 1.41, P = 0.026), prolonged operative time (OR = 2.12, P = 0.001), and ASA physical status of ≥3 (OR = 1.69, P < 0.001) as independently associated with higher incidences of postoperative surgical complications. A multivariate regression analysis identified class II or III obesity (OR = 1.70, P = 0.003), contaminated or dirty/infected wounds (OR = 1.95, P < 0.001), diabetes (OR = 1.96, P = 0.001), pulmonary comorbidity (OR = 2.08, P = 0.005), and component separation (OR = 2.65, P < 0.001) as independently associated with higher incidences of postoperative medical complications. Simplified risk models of surgical and medical morbidity demonstrated good discrimination with C statistics of 0.69 and 0.70, respectively. We report a simple preoperative, internally-validated risk model of surgical and medical morbidity following VHR-PAN to guide patient selection. Prognostic/risk category, level II

The objective of this study was to evaluate the mechanical and histological properties of a fully absorbable poly-4-hydroxybutyrate/absorbable barrier composite mesh (Phasix™ ST) compared to partially absorbable (Ventralight™ ST), fully absorbable (Phasix™), and biologically derived (Strattice™) meshes in a porcine model of ventral hernia repair. Bilateral abdominal surgical defects were created in twenty-four Yucatan pigs, repaired with intraperitoneal (Phasix™ ST, Ventralight™ ST) or retromuscular (Phasix™, Strattice™) mesh, and evaluated at 12 and 24 weeks (n = 6 mesh/group/time point). Prior to implantation, Strattice™ demonstrated significantly higher (p < 0.001) strength (636.6 ± 192.1 N) compared to Ventralight™ ST (324.3 ± 37.1 N), Phasix™ ST (206.9 ± 11.3 N), and Phasix™ (200.6 ± 25.2 N). At 12 and 24 weeks, mesh/repair strength was significantly greater than NAW (p < 0.01 in all cases), and no significant changes in strength were observed for any meshes between 12 and 24 weeks (p > 0.05). Phasix™ mesh/repair strength was significantly greater than Strattice™ (p < 0.001) at 12 and 24 weeks, and Ventralight™ ST mesh/repair strength was significantly greater than Phasix™ ST mesh (p < 0.05) at 24 weeks. At 12 and 24 weeks, Phasix™ ST and Ventralight™ ST were associated with mild inflammation and minimal-mild fibrosis/neovascularization, with no significant differences between groups. At both time points, Phasix™ was associated with minimal-mild inflammation/fibrosis and mild neovascularization. Strattice™ was associated with minimal inflammation/fibrosis, with minimal neovascularization at 12 weeks, which increased to mild by 24 weeks. Strattice™ exhibited significantly less neovascularization than Phasix™ at 12 weeks and significantly greater inflammation at 24 weeks due to remodeling. Phasix™ ST demonstrated mechanical and histological properties comparable to partially

Spigelian hernia is a rare type of ventral hernias with nonspecific symptoms and signs. Therefore, its diagnosis is often difficult and requires more clinical attention. Although intermittent abdominal swelling and pain are the main symptoms, Spigelian hernias can be sometimes asymptomatic and are discovered incidentally at the operation. In some cases, these hernias can be associated with other abdominal wall hernias, therefore a detailed physical examination of the patients is necessary to avoid mistakes in diagnosis. Herein, we report an interesting and educational case of Spigelian hernia with accompanying ipsilateral both direct and indirect inguinal hernias in a male patient treated by open surgical repair with use of polypropylene mesh.
Early postoperative and one year results of a randomized controlled trial comparing the impact of extralight titanized polypropylene mesh and traditional heavyweight polypropylene mesh on pain and seroma production in laparoscopic hernia repair (TAPP).
Bittner, R; Schmedt, C-G; Leibl, B J; Schwarz, J
Today the main goals of inguinal hernia repair are maximum postoperative comfort and a minimal rate of chronic pain. This randomized trial compares these parameters after laparoscopic hernia repair (TAPP) using an extralight titanized polypropylene mesh (ELW group) TiMesh(®) 16 g/m(2) without any fixation with those using a standard heavyweight mesh (HW) Prolene 90 g/m(2) fixed in a standardized way with two absorbable sutures. Three hundred patients with an inguinal hernia and a defect diameter ≤3 cm were included in the trial. Patients were assessed for pain, foreign body sensation, and physical activities preoperatively, early postoperatively, at 4 weeks, 6 months, and 1 year by questionnaire and were examined clinically. Postoperatively, seroma formation was measured by ultrasound. One year after TAPP, the frequency of chronic pain was not greater than 3%, with no difference between the two mesh groups; in no patient was intensity of pain higher than VAS 40. In the early postoperative period, 40% of the patients in the titanized ELW group needed pain medication compared with 52.7% in the HW group (P = 0.0378). Foreign body sensation was not different between the groups but there was significantly less impairment of physical activities (P = 0.0425) and seroma production (P = 0.0415) in the titanized ELW group compared to the HW group in the early postoperative period. Use of titanized ELW mesh for laparoscopic hernia repair did not affect the rate of chronic pain but it seems to improve early postoperative convalescence. Its use without any fixation can be recommended in TAPP for inguinal hernia patients with a defect size ≤3 cm.

Factors leading to seroma following ventral incisional herniorrhaphy (VIH) are poorly understood. Between 2004 and 2006, patients were prospectively randomized at 4 Veterans Affairs hospitals to undergo laparoscopic or open VIH. Patients who developed seromas within 8 weeks postoperatively were compared with those who did not. Multivariate analyses were performed to identify predictors of seroma. Of 145 patients who underwent VIH, 24 (16.6%) developed seromas. Patients who underwent open VIH had more seromas than those who underwent laparoscopic VIH (23.3% vs 6.8%, P = .011). Seroma patients had hernias that were never spontaneously reducible (0% vs 21%, P = .015), had more abdominal incisions preoperatively (mean, 2.4 vs 1.8; P = .037), and were less likely to have drain catheters placed than those without seromas (30.0% vs 63.1%, P = .011). In multivariate analyses, open VIH predicted seroma (odds ratio, 5.5; 95% confidence interval, 1.6-18.8), as well as the specific hospital at which the procedure was performed. Spontaneous resolution occurred in 71% of seromas; 29% required aspiration. Procedural characteristics and hernia characteristics rather than patient comorbidities predicted seroma in VIH.

Amyand’s hernia is defined as when the appendix is trapped within an inguinal hernia. While the incidence of this type of hernia is rare, the appendix may become incarcerated within Amyand’s hernia and lead to further complications such as strangulation and perforation. Incarceration of the appendix most commonly occurs within inguinal and femoral hernias, but may arise to a lesser extent in incisional and umbilical hernias. Incarcerated appendix has been reported in a variety of ventral abdominal and inguinal locations, yet its indistinct clinical presentation represents a diagnostic challenge. This paper reviews the literature on incarceration of the appendix within inguinal hernias and discusses current approaches to diagnosis and treatment of Amyand’s hernia and complications that may arise from incarceration of the appendix within the hernia.

A classification of parastomal hernias (PH) is needed to compare different populations described in various trials and cohort studies, complete the previous inguinal and ventral hernia classifications of the European Hernia Society (EHS) and will be integrated into the EuraHS database (European Registry of Abdominal Wall Hernias). Several members of the EHS board and invited experts gathered for 2 days to discuss the development of an EHS classification of PH. The discussions were based on a literature review and critical appraisal of existing classifications. The classification proposal is based on the PH defect size (small is ≤5 cm) and the presence of a concomitant incisional hernia (cIH). Four types were defined: Type I, small PH without cIH; Type II, small PH with cIH; Type III, large PH without cIH; and Type IV, large PH with cIH. In addition, the classification grid includes details about whether the hernia recurs after a previous PH repair or whether it is a primary PH. Clinical validation is needed in the future to assess if the classification allows us to differentiate the treatment strategy and if the classification impacts outcome in these different subgroups. A classification of PH divided into subgroups according to size and cIH was formulated with the aim of improving the ability to compare different studies and their results.

Laparoscopic approach is now generally accepted for the treatment of incisional hernia. The ideal mesh is still to be found. The aim of this study is to compare the well-known Gore® DUALMESH® Plus (WL Gore & Associates, Flagstaff, AZ) to a new prosthesis, the DynaMesh®-IPOM (FEG Textiltechnik GmbH, Aachen, Germany), to clinically verify its potential benefits in the laparoscopic treatment of incisional hernia. Comparing the results of the laparoscopic treatment of two groups of patients affected by incisional hernia using Gore® DUALMESH® Plus and DynaMesh®-IPOM. There were 45 females and 31 males, with age variable from 21 to 84 years of age. The two groups were well matched for age (median age 60 years for group A and 57.6 years for group B-p=0.44) and sex (28F and 17M group A and 13 F and 18 M group B-p=0.008), while median BMI resulted slightly higher in group B (26.12 group A and 29.74 group B-p=0.001). The median size of the defect was similar in the two groups (87.5 mm group A and 83.4 mm for group B-p=0.83), while the median operating time was slightly longer in group A (77 min group A and 67 min group B-p=0.44). No difference in the length of hospital stay was evidenced between the two groups (3.19 days for group A and 3 days for group B-p=0.74). Time to return to physical activity was similar between the two groups (13.46 days for group A and 12.7 days for group B-p=0.32). Minor complications occurred in 15 cases (19.7%): seromas (7 cases), prolonged ileus (6 cases), and hemoperitoneum (2 cases), without significant difference in the incidence of such complications in the two groups. Five recurrences (6.5% of cases) occurred. No differences in the recurrence rate was noted between the two groups (3 cases/7% for group A and 2 cases/6% for group B-p=00.7). DynaMesh®-IPOM proved to be a safe and effective mesh for the laparoscopic repair of incisional hernia even when compared to DUALMESH® Plus.

Background and Objectives: Inguinal hernia repair is among the most common procedures performed worldwide and the laparoscopic totally extraperitoneal (TEP) approach is a recognized and effective surgical technique. Although technically advantageous because of the option of no mesh fixation and no need for creation of a peritoneal flap resulting, in less postoperative pain and faster recovery, TEP has not achieved the popularity it deserves, mainly because of its complexity and steep learning curve. Minilaparoscopy was first described in the 1990s and has recently gained significantly from better instrumentation that may increase TEP's effectiveness and acceptance. We performed a prospective study, to analyze the outcomes of minilaparoscopy in pain and operative time when compared to the conventional laparoscopic technique in hernia repair. Methods: Fifty-eight laparoscopic inguinal hernia repairs were performed: 36 by traditional laparoscopic technique and 22 by minilaparoscopic instruments (mini). A study protocol was applied prospectively for data collection. Variables analyzed were early postoperative pain (at hour 6 after procedure), pain at discharge, use of on-demand analgesics, and operative time. Results: The mini group presented reduced early postoperative pain and operative time. The present study also suggests less postoperative pain at discharge with mini procedures, although this difference was not statistically significant. No difference between the groups regarding on-demand use of analgesics was found. Conclusions: This study corroborates findings in previously published papers that have shown the feasibility of minilaparoscopy in laparoscopic TEP hernia repair and its benefits regarding postoperative pain, operative time, and aesthetic outcomes.

There is very scant literature on the impact of inguinal hernia mesh repair on testicular functions and sexual functions following open and laparoscopic repair. The present randomized study compares TAPP and TEP repairs in terms of testicular functions, sexual functions, quality of life and chronic groin pain. This study was conducted from April 2012 to October 2014. A total of 160 patients with uncomplicated groin hernia were randomized to either trans-abdominal pre-peritoneal (TAPP) repair or totally extra-peritoneal (TEP) repair. Testicular functions were assessed by measuring testicular volume, testicular hormone levels preoperatively and at 3 months postoperatively. Sexual functions were assessed using BMSFI, and quality of life was assessed using WHO-QOL BREF scale preoperatively and at 3 and 6 months postoperatively. Chronic groin pain was evaluated using the VAS scale at 3 months, 6 months and at 1 year. The median duration of follow-up was 13 months (range 6-18 months). The mean preoperative pain scores (p value 0.35) as well as the chronic groin pain were similar between TEP and TAPP repairs at 3 months (p value 0.06) and 6 months (p value 0.86). The testicular resistive index and testicular volume did not show any significant change at follow-up of 3 months (p value 0.9) in the study population. No significant difference was observed in testicular resistive index and testicular volume when comparing TEP and TAPP groups at at follow-up of 3 months (p value >0.05). There was a statistically significant improvement in the sexual drive score, erectile function and overall satisfaction over the follow-up period following laparoscopic inguinal hernia repair. However, sexual function improvement was similar in patients undergoing both TEP and TAPP repairs. All the domains of quality of life in the study population showed a significant improvement at a follow-up of 3 and 6 months. Subgroup analysis of all the domains of quality of life in both TAPP

Old male Collies, Pekingese , Boxers and Boston Terriers are predisposed to perineal hernia. Recurrence is often related to poor surgical technic in the initial repair. With the anesthetized dog in sternal recumbency and the tail tied forward, a curvilinear skin incision is made over the hernia, from the tail base to the midline, ventral to the anus. The hernial sac is opened and its contents reduced. Five stainless-steel sutures are preplaced in the muscles and ligaments of the perineal diaphragm and tied from top to bottom. In cases of failure of the ventral aspect of the repair, the internal obturator muscle can be elevated from the ischial table and used to cover the ventral aspect of the hernia. Postoperative complications are related to infection, self-trauma and straining.

To describe the incidence and treatment of prevascular and retropsoas hernias in a large-volume general surgery practice. Femoral hernias are considered uncommon with an incidence between 2 and 8 % of groin hernias. There are no large studies describing the subtypes of femoral hernias or retropsoas hernias, and therefore no reported incidence or standardized treatment recommendations for these hernias exist. This study is a retrospective review of all patients undergoing total extraperitoneal (TEP) laparoscopic herniorrhaphy between August 1993 and December 2011. A single surgeon performed all the repairs. Demographics and patient outcomes were reported. 2,436 patients underwent 3,242 TEP repairs. The subtypes were: indirect 1,523 (46.9 %), direct 1,473 (45.4 %), femoral 156 (4.8 %), obturator 35 (1.1 %), prevascular 25 (0.77 %), Spigelian 20 (0.61 %), retropsoas 3 (0.09 %). Prevascular hernias accounted for 16 % of femoral hernias. Patients with prevascular hernias had a mean age of 70.3 years and were all male. 13 of the 25 patients (52 %) with prevascular hernias had other associated defects and four (16 %) of the patients had prevascular hernias as a recurrence from a prior hernia operation. There were three patients with retropsoas hernias that only would not have been seen from an anterior open approach. There are no intraoperative complications or known recurrences from this study group. Prevascular and retropsoas hernias are uncommon, but have a higher incidence than previously believed. Prevascular hernias tend to be associated with older age and other defects. The diagnosis and management of these hernias are readily achieved using the laparoscopic TEP approach.

Hernias are very familiar to a core surgical trainee in the setting of clinics and the surgical assessment unit. By definition, a hernia is an abnormal protrusion of a viscus from one compartment to another. In clinic, they are visible lumps, exhibiting a cough reflex often with a well definable history making them readily identifiable. In the acute setting, they are the third commonest cause of small bowel obstruction in the developed world. Ventral and inguinal hernias account for the majority of these with only a small proportion due to internal hernias. This article aims to educate the core surgical trainee on the anatomy and distinguishing clinical features of these rare but important types of internal abdominal hernias.

An interstitial hernia is one in which the hernia sac is located between the layers of the abdominal wall. The analysis of contemporary literature shows that interstitial hernias are most often seen in children as a type of inguinal hernia and often accompany undescended testis. The hernia sac is usually located between the external-oblique and internal-oblique muscles in a lateral-cephalic direction. The authors present 3 cases of interstitial hernia found during laparoscopic exploration of the front abdominal wall done due to incisional wound site pain. No previous diagnosis of hernia was considered in all the cases. Hernias were found as complications of appendectomy and wound healing after radiotherapy of uterine and cervical cancer. In conclusion, in obscure wound site pain, the presence of an interstitial postoperative hernia should be considered as a possible reason for the complaint. Laparoscopic examination of the anterior abdominal wall during adhesiolysis in patients with abdominal pain enables proper diagnosis and treatment.

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.

It is generally stated that preoperative differentiation between indirect and direct inguinal hernias by physical examination is inaccurate and irrelevant. With the expansion of the laparoscopic technique, new relevance has emerged. Laparoscopic correction of an indirect hernia is more challenging and time consuming than laparoscopic correction of a direct hernia. Preoperative knowledge concerning the type of hernia informs the laparoscopic surgeon about the required expertise and the expected operative time, and this knowledge is useful for training programs and management. The authors therefore developed a new accurate and easy method of physical examination to differentiate types of inguinal hernia. A prospective study was conducted to determine the accuracy of this new method that combines physical examination with a hand-held Doppler device (not ultrasound) to differentiate types of inguinal hernia. This prospective diagnostics study consisted of two consecutive parts. Each part included 100 consecutive patients presenting with an inguinal hernia. The inguinal occlusion test was used to differentiate the types of inguinal hernia during physical examination in the first part of the study. A hand-held Doppler device was used for adequate localization of the epigastric vessels in addition to the occlusion test in the second part of the study. Preoperative remarks were compared with findings during laparoscopic inguinal hernia repair. The McNemar symmetry χ (2) test was used for statistical evaluation The first part of the study showed a preoperative accuracy of 35 % for direct inguinal hernias and 86 % for indirect inguinal hernias (p < 0.001). The second part of the study showed a preoperative accuracy of 79 % for direct inguinal hernias and 93 % for indirect inguinal hernias (p < 0.001) CONCLUSION: The inguinal occlusion test combined with the use of a handheld Doppler device is accurate in distinguishing direct and indirect inguinal hernias and provides

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.
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.

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.

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.

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.

The present study was performed by the Spanish Association of surgeons through its abdominal wall and sutures section. The aim was to determine the current situation of inguinofemoral hernias in Spain and was based on an anonymous multicenter study with the participation of various national hospitals. Fifty general surgery departments in distinct surgical centers throughout Spain responded to an anonymous survey in 2000. The survey gathered data on anesthetic features, surgical techniques and complications in the treatment of inguinofemoral hernias. Sixty-six percent of hospital centers had a specific abdominal wall unit and 24% performed laparoscopic hernia surgery. Prosthetic techniques (especially Lichtenstein) were the most frequently used in the treatment of primary inguinal hernia (72%) and recurrent hernia (100%). The most frequently used prosthetic material was polypropylene mesh (76%). Only 28% of the departments surveyed performed anatomic techniques in the repair of primary inguinal hernia (Shouldice and Bassini). The most frequent treatment for femoral hernia was the Lichtenstein "plug" (78%). Sixty-eight percent of the centers surveyed performed regional anesthesia, 18% used general anesthesia and only 14% used local anesthesia with sedation. Severe complications were found in 20% of departments. Clinical postoperative follow-up was performed in 96% of the centers and telephone follow-up was used in 4%. The recurrence rate was 1.2% for primary inguinal hernia, 2.7% for recurrent inguinal hernia and 0.3% for femoral hernia. In Spain the most commonly used surgical technique in the treatment of inguinal hernia is Lichtenstein hernioplasty under spinal anesthesia and with polypropylene prosthesis. The Lichtenstein plug is the most commonly used technique in the treatment of femoral hernia.

Healthcare systems and surgeons are under increasing pressure to provide high-quality care for the lowest possible cost . This study utilizes national data to examine the outcomes and costs of common laparoscopic procedures based on hospital type and location. The National Inpatient Sample was queried from 2008 to 2011 for five laparoscopic procedures: colectomy (LC), inguinal hernia repair, ventral hernia repair (LVHR), Nissen fundoplication (NF), and cholecystectomy (LCh). Outcomes, including complication rate and inpatient mortality, were stratified by region and hospital type. Both univariate and multivariate regression analyses were performed using regression-based survey methods; risk-adjusted mean costs for hospital were calculated after adjusting for patient characteristics. In univariate analysis, the rates of minor complications varied significantly between geographic regions for LCh, LC, NF, and LVHR (p < 0.05). Though LCh and LVHR had statistical variation between regions for rates of major complications (p < 0.05), all regions were equivalent in rates of inpatient mortality for the procedures (p > 0.05). Rural and urban centers had similar rates of complications (p > 0.05), except for higher rates of major complications following IHR and LC in rural centers (p < 0.02) and following Nissen fundoplication in urban facilities(p < 0.0003). Though urban centers were more expensive for all procedures (p < 0.0001), mortality was similar between groups (p > 0.05). For hospital ownership, private investor-owned facilities were substantially more expensive (p < 0.0001), but had no significant differences in complications compared to other hospital types (p > 0.05). In multivariate analysis, while patient factors helped explain differences between outcome differences in different hospital types and locations, in general, the difference in cost remained statistically significant between hospitals. Though patient demographics and characteristics accounted for some

The aim of this systematic review was to determine the exact volume and growth pattern of articles on abdominal wall hernias, in particular the effect of the journal Hernia on publications about hernias. A PubMed search was performed for every year between 1965 and 2010, using the title words "inguinal hernia," "incisional hernia," and "umbilical hernia." Then, two consecutive 10-year periods were chosen for a systematic PubMed search, before and after 2001--the year in which Hernia began to be indexed in PubMed. The main keywords used were as follows: "inguinal hernia" "incisional hernia" "umbilical hernia" "mesh" "laparoscopic" and "experimental." The number of all articles indexed in PubMed increased 1.6-fold between the periods 1991-2000 and 2001-2010. The number of articles with the title word "inguinal hernia" increased 1.7-fold, whereas the rises for incisional and umbilical hernias were more prominent: 3.9- and 2.6-fold. Article titles with the combined keywords "hernia and mesh" and "hernia and laparoscopic" increased 2.8- and 2.4-fold. The most striking combined search was for "umbilical hernia and mesh" with a 20.5-fold rise. The percentage of articles published in the journal Hernia among all articles in all 25 selected journals, including Hernia was 30% on average. Hernia, Surgical Endoscopy and the British Journal of Surgery were the leading journals for publications for inguinal hernia in the last decade. Growth in hernia papers is greater than the overall growth in PubMed. Articles on incisional hernia increased faster than did those on inguinal and umbilical hernias. The establishment and indexing of Hernia decreased the proportion of hernia publications in other journals. The core journals for herniology are Hernia, Surgical Endoscopy, and the British Journal of Surgery.
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

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.

Aim To evaluate the role of laparoscopy in the treatment of surgical emergency in old population. Patients and Methods Over-70 years-old patients submitted to emergency abdominal surgery from January 2013 to December 2014 were collected and grouped according to admission diagnoses. These accounted small bowel obstruction, colonic acute disease, appendicitis, ventral hernia, gastro-duodenal perforation, biliary disease. In each group it was analyzed the operation time (OT), the morbidity rate and the mortality rate comparing open and laparoscopic management using T-test and Chi-square test. Results 159 over 70-years-old patients underwent emergency surgery in the General and Emergency surgery Operative Unit (O.U.) of the Policlinic of Palermo. 75 patients were managed by a laparoscopic approach and 84 underwent traditional open emergency surgery. T-Test for OT and Chi-square test for morbidity rate and mortality rate showed no differences in small bowel emergencies (p=0,4; 0,25

Inguinal hernia repair and pyloromyotomy are among the most common operations performed on children. In the last two decades minimally invasive surgery has been employed for an increasing number of these procedures. This review describes the development of the techniques involved, and their current role in therapy. A systematic review of the paediatric surgical literature since 1990 was performed on laparoscopic inguinal hernia repair and pyloromyotomy. Relevant publications were summarised. The first laparoscopic pyloromyotomy was described in 1991, the first laparoscopic inguinal hernia repair in children was published in 1998. The learning curve for both procedures is initially steep and reaches a plateau only after about 20 to 30 cases. Both randomised controlled trials and meta-analyses are available comparing the laparoscopic and open techniques for both procedures. The advantages of laparoscopic versus open pyloromyotomy include faster recovery and shorter hospital stay, at similar complication rates. The operation times of laparoscopic inguinal hernia repair are shorter in bilateral cases, while the complication rate again is similar. However, the incidence of metachronous contralateral inguinal hernia is lower after laparoscopic repair. Laparoscopic pyloromyotomy and paediatric inguinal hernia repair require special skills. As a minimum, a surgeon's first 20 cases should therefore be performed under competent supervision. Besides resulting in smaller scars, both procedures have concrete advantages and the same complication rates compared to the open techniques. Therefore, both operations can be regarded as the current gold standard. Georg Thieme Verlag KG Stuttgart · New York.
A lightweight polypropylene mesh (TiMesh) for laparoscopic intraperitoneal repair of abdominal wall hernias: comparison of biocompatibility with the DualMesh in an experimental study using the porcine model.
Schug-Pass, C; Tamme, C; Tannapfel, A; Köckerling, F
showed significantly higher values for ePTFE than for TiMesh (p = 0.011). The apoptosis index was significantly higher for the ePTFE membranes (p = 0.002). Titanium-coated polypropylene mesh (TiMesh) is clearly superior to the DualMesh in terms of biocompatibility, and is thus suitable for the laparoscopic intraperitoneal repair of abdominal wall and incisional hernias.

The Toy-Smoot laparoscopic hernioplasty has been performed on 75 patients with a total of 83 hernioplasties over the past 20 months. Sixty-nine patients were male and six were female. The age range was 20 to 75 years with an average age of 51.5 years. Twelve of the patients had bilateral hernias repaired: 55 direct hernias, 16 indirect hernias, and 5 pantaloon hernias. Eleven of the repairs were for recurrent hernias. The procedure was performed under general anesthesia. The abdomen was insufflated with carbon dioxide, establishing the pneumoperitoneum. Three 11 mm trocars were inserted, the first via the umbilicus, into which the 0 degrees endoscope was inserted. Two additional trocars were inserted at the level of the umbilicus at the anterior axillary lines. The hernia sacs were left in situ. The medial umbilical ligament was dissected medially, so as to identify directly the pubic tubercle and the Cooper's ligament. An expanded PTFE soft tissue patch, 1 mm thick and 7.5 x 10 cm in size, was attached to the Nanticoke Endo-patch spreader and introduced via the contralateral trocar and positioned over the hernia defect. The Endopath EMS stapler was then used to secure the PTFE patch over the hernia defect. This required secure anatomical fixation to the transversalis fascia anteriorly and laterally, the pubic tubercle, and the posterior rectus sheath, medially, Cooper's ligament, posteromedially, and the endoabdominal fascia, posterolaterally. There were a total of seven different complications, one major, which was a bladder injury that required an open repair of the bladder and then an open, conventional hernioplasty.(ABSTRACT TRUNCATED AT 250 WORDS)

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.

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.
