SP1.2 - Laparoscopic versus Robotic ventral hernia repair: a systematic review and meta-analysis comparing the perioperative outcomes randomised controlled trials

Abstract Objective The objective of this meta-analysis is to compare the perioperative surgical outcomes and cost-effectiveness of robotic incisional/ventral hernia repair (RIVHR) versus laparoscopic incisional/ventral hernia repair (LIVHR). Methods Randomised control trials (RCTs) reporting perioperative outcomes and costs in patients undergoing RIVHR versus LIVHR were selected from medical electronic databases and meta-analysis was conducted under the guidelines of the Cochrane Collaboration using statistical software RevMan version 5. Results Four RCTs on 337 patients reporting perioperative outcomes and cost comparison were included. In the random effect model analysis, the duration of operation [standardized mean difference (SMD) -48.07, 95%, CI (-78.06, -18.07), z = 3.14, p = 0.002] was shorter and cost was lower [SMD 0.82, 95%, CI (-1.48, -0.16), z = 2.45, p = 0.01] in the LIVHR group but with significant statistical heterogeneity. However, the variables of hernia recurrence [risk ratio (RR) 2.29, 95%, CI (0.73, 7.12), z = 1.43, p = 0.15] and surgical site complications [RR 0.85, 95%, CI (0.48, 1.50), z = 0.55, p = 0.58] were statistically similar in both groups without any statistical heterogeneity among the included studies. Conclusion The RIVHR does not offer any superiority over LIVHR in all perioperative variables and it is not cost effective. Due to the paucity of the RCTs, a major multi-centre RCT is needed to validate these findings.

Outcomes after ventral hernia repair using the extended totally extraperitoneal approach: Initial experience from the Philippines.

Newer extraperitoneal techniques of laparoscopic ventral/incisional hernia repair (LVIHR) have been continually introduced since the popularity of the laparoscopic intraperitoneal onlay mesh technique began in 1993. One of which is the extended totally extraperitoneal (eTEP) approach allowing wide mesh augmentation, concurrent repair of diastasis recti, and performance of transversus abdominis release (TAR) for large/complex hernias. However, minimally invasive/laparoendoscopic ventral hernia repair is not yet widely adopted in the Philippines. We aim to share our preliminary experience with LVIHR using the eTEP approach. This was a retrospective review of all consecutive eTEP repairs for ventral hernia between January 2019 and September 2023. The clinical profiles of all patients were gathered. Hernia characteristics, operative profile, and postoperative outcomes were reported. Thirty-five patients were included in the study with a mean age of 54.7; 60% were incisional hernias, and the most common hernia location was the umbilical area. A defect size between 4 and 10 cm was reported in 54.3%. eTEP-TAR was necessary in 12 patients. At a median follow-up of 16 months, two patients developed seroma, one hematoma, and two surgical site infections. All were successfully managed conservatively. Only one patient developed recurrence. eTEP approach is safe and feasible for repairing ventral hernias. Our preliminary experience showed acceptable outcomes similar to the published literature. Surgeons interested in this technique should be familiar with the abdominal wall anatomy, carefully select patients during preoperative planning, and undergo mentorship with hernia surgeons experienced with the technique to shorten the learning curve.

Laparoscopic versus hybrid approach for treatment of incisional ventral hernia: a 5–10-year follow-up of the randomized controlled multicenter study

PurposeIn this long-term follow-up of a prospective, randomized, and multicenter study, we compare the results of a group receiving laparoscopic incisional ventral hernia repair using intraperitoneal onlay mesh (LG) to a group receiving a hybrid hernia repair where open closure of fascial defect was added to intraperitoneal mesh placement (HG).MethodsOriginally, 193 patients with 2–7 cm incisional hernias were randomly assigned to either the LG or HG during the 30-month recruitment period in 2012 to 2015. Long-term follow-up was conducted 5–10 years after surgery to evaluate hernia recurrence rate and quality of life (QoL).ResultsIn all, 65 patients in the LG and 60 in the HG completed the long-term follow-up with a median follow-up period of 87 months. Recurrent hernia was detected in 11 of 65 patients (16.9%) in the LG and 10 of 60 patients (16.7%) in the HG (p > 0.9). Kaplan–Meier analysis demonstrated a recurrence rate approaching 20% in both groups, with similar curves. Three patients in the LG (4.6% and five patients in the HG (8.1%) had undergone re-operation due to recurrence (p = 0.48). There was no difference in patient-reported QoL measured using the SF-36 questionnaire. Mean pain scores were similar between groups, mean numeric rating scale (NRS) 0 to 10 being 1.1 in the LG and 0.7 in the HG (p = 0.43).ConclusionFascial closure did not reduce hernia recurrence rate in this study population, even though it has been shown to be beneficial and recommended in surgery guidelines. In the long term, recurrence rate for both groups is similar.

P069 IMPLEMENTATION OF A TAP BLOCK PROTOCOL IN OUTPATIENT LAPAROSCOPIC HERNIA REPAIR DURING COVID PANDEMIC

Abstract Aim “COVID has been a great challenge since its beginning. Hospitals had to change/create a lot of clinical pathways and protocols to fight it. As an adaptation to COVID pandemic, our surgical department decided to implement a protocol of Transversus Abdominis Plane Block (TAPB) in laparoscopic incisional ventral hernia repair to allow these patients to be shifted from elective to outpatient regime. This study aimed to analyze the implementation of this protocol during the covid era as a way to have more resources available for COVID patients.” Material and Methods “A retrospective observational study was conducted using data since the beginning of the implementation of the protocol, from July 2020 to May 2021. TAPB was performed in all patients, laparoscopically or ultrasound-guided. Patients and hernia variables were identified using the hospital database. Data was recorded in the recovery room, by a phone call 24h post-surgery and in postoperative consultations with the surgeon.” Results “A total of 18 patients with incisional ventral hernia was included in the study. All patients had laparoscopic incisional ventral hernia repair surgery with TAPB and in ambulatory regime, discharged before 24h, are very satisfied with the protocol in terms of post-operative pain and there are no complications related to the TAPB.” Conclusions “This study found that, despite of COVID Pandemic, implementing a TAP Block procedure during laparoscopic incisional ventral hernia repair, allows to shift these patients from elective to outpatient surgery without compromising the outcomes, pain management and patient security, and, finally, to increase availability of resources for COVID patients.”

SP7.2.2 Fascial defect closure in laparoscopic incisional/ventral hernia: a systematic review and meta-analysis of published randomized, controlled trials

Abstract Aims Closure of fascial defect (CFD) during laparoscopic incisional/ventral hernia repair (LIVHR) remains a controversial issue which requires further investigations to reach a solid conclusion. The objective of this study is to present a systematic review comparing the outcomes of randomized controlled trials evaluating the defect closure versus no-defect closure in patients undergoing LIVHR. Methods A systematic review of randomized, controlled trials reporting the fascial defect closure in patients undergoing LIVHR until January 2021 published in Embase, Medline, PubMed, PubMed Central and Cochrane databases was performed using the principles of meta-analysis. Results A total of four RCTs involving 443 patients were included. In the random effects model analysis, using the statistical software Review Manager, defect closure during LIVHR showed no difference in hernia recurrence (risk ratio (RR), 0.89; 95% CI, 0.31, 2.57; z = 0.21; P = 0.84). In addition, the post-operative complications (RR, 0.69; 95% CI, 0.41, 1.16; z = 1.41; P = 0.16), duration of operation (Standardized mean difference (SMD), -0.04; 95% CI, -0.52, 0.43; z = 0.18; P = 0.86) and hospital stay (SMD, 0.27; 95% CI, -0.02, 0.56; z = 1.80; P = 0.07) were also statistically similar in both groups. CFD was associated with an increased post-operative pain score (SMD, 1.82; 95% CI, 0.61, 3.03; z = 2.95; P = 0.003). Conclusion Fascial defect closure in patients undergoing LIVHR does not demonstrate any superiority over no-defect closure in terms of recurrence, post-operative morbidity, post-operative pain duration of operation and length of hospital stay.

Subcutaneous switching suture technique for hernia defect closure during laparoscopic ventral and incisional hernia repair.

IntroductionA vertical penetration of the thread through the abdominal wall for the hernia defect closure in laparoscopic ventral/incisional hernia repair (LVIHR) is difficult especially in the large defect cases when applying the existing techniques.MaterialsSixteen LVIHRs were performed using the suture technique for defect closure we newly developed.Surgical techniqueWith the subcutaneous switching, our technique only requires the suture‐passer and easily enables the vertical penetration of the thread through the abdominal muscular wall even in the large defect cases.DiscussionThe defect closure in LVIHR tends to be complicated in the large defect cases. Thus, we devised this technique for the easy, reliable, and firm closure even in the large defect cases. Although the sample size was currently very small, we consider that the favorable outcomes have been obtained through our technique because any noticeable complications, such as mesh bulging or recurrence, have not been observed currently.

Hybrid technique for laparoscopic incisional ventral hernia repair combining laparoscopic primary closure and mesh repair.

Incisional ventral hernia is one of the most common surgical complications after laparotomy. Laparoscopic repair of incisional ventral hernia has been conducted recently, and the advantages of this procedure have been reported. However, in large orifice cases, the recurrence rate is increased. To improve recurrence rates in large cases, a hybrid method combining laparoscopic primary closure and mesh repair can be applied. Monofilament thread was inserted into the abdominal cavity for hernia closure and pulled from the other side of the orifice. The same procedure was performed from the upper side to the lower side without closure, and all thread was placed in line. Both sides of the thread were then introduced to the midline of the incision through a subcutaneous route. This procedure was conducted with an introducer. All threads were tied, and then a mesh was placed. Hybrid techniques already combine mini-laparotomy for hernia closure and subsequent laparoscopic intraoperative onlay mesh for reinforcement, but such techniques require laparotomy. In our technique, closure of the linea alba does not require laparotomy. All procedures were performed laparoscopically. This procedure is very easy and safe, and does not require the abdominal cavity to be opened. Thus, hybrid methods are effective for treating cases of incisional hernia involving a large orifice.

Iatrogenic enterotomy in laparoscopic ventral/incisional hernia repair: a single center experience of 2,346 patients over 17 years

Iatrogenic enterotomy (IE) during laparoscopic ventral/incisional hernia repair (LIVHR) is reported to be associated with poorer surgical outcomes. We report our experience with diagnosis, management and complications in patients who had IE during LIVHR at our tertiary referral institute between 1994 and 2011. We retrospectively reviewed prospectively collected data of 2,346 patients who underwent LIVHR from 1994 to 2011. We identified 33 patients who had IE during LIVHR. All surgical procedures were performed by five consultants and fellows under supervision who followed a standardized operative protocol. Patients were followed up for 6months to evaluate morbidity, mortality, additional surgical procedures, unplanned readmissions and hospital stay. Mortality occurred in 2 patients (6%). Complications occurred in 16 patients (48.5%). Median hospital stay was 3days (2-36). Unplanned readmission was required in 6 patients (18%). In 18 patients, (55%) additional surgical procedures were required within 6months of LIVHR. In 5 patients, the enterotomy was recognized postoperatively. These patients had worst outcomes [mortality 40%, additional surgical procedures were required in all patients (100%) and median hospital stay was 12days (range 7-36)]. Iatrogenic enterotomy is a serious complication during LIVHR. IE is associated with mortality, morbidity, additional surgical procedures, unplanned readmissions and prolonged hospital stay. In patients where IE was recognized postoperatively, the prognosis was worst.

Laparoscopic ventral incisional hernia repair: evidence-based guidelines of the first Italian Consensus Conference

The laparoscopic treatment of ventral incisional hernias is the object of constant attention and is becoming increasingly widespread in the international scientific-surgical community; however, there is ample debate on its technical details and indications. In order to establish a common approach on laparoscopic ventral incisional hernia repair, the first Italian Consensus Conference was organized in Naples (Italy) on 14-15 January 2010. The format of the Consensus Conference was freely adapted from the standards of the National Institute of Health and the Italian Health Institute. The parties involved included the followings: a Promotional Committee, a Scientific Committee, a group of Experts, the Jury Panel and a Scientific Secretariat. Eleven statements, regarding three large chapters on the indications, the technical details and the management of complications were drafted on the basis of literature references collected by the Scientific Committee, documents developed by the Experts, reports presented and discussed during the Consensus Conference, and discussion among the members of the Jury. The laparoscopic approach is safe and effective for defects larger than 3cm in diameter; old age, obesity, previous abdominal operations, recurrence and strangulation are not absolute contraindications. Ensuring an adequate overlap, careful adhesiolysis and correct fixing of the prosthesis are among the technical details recommended. Complications and recurrences are comparable to, and in some cases, less numerous than with the open approach.

Does expanded polytetrafluoroethylene mesh really shrink after laparoscopic ventral hernia repair?

The shrinkage of mesh has been cited as a possible explanation for hernia recurrence. Expanded polytetrafluoroethylene (ePTFE) is unique in that it can be visualized on computed tomography (CT). Some animal studies have shown a greater than 40% rate of contraction of ePTFE; however, very few human studies have been performed. A total of 815 laparoscopic incisional/ventral hernia (LIVH) repairs were performed by a single surgical group. DualMesh Plus (ePTFE) (WL Gore & Associates, Newark, DE) was placed in the majority of these patients using both transfascial sutures and tack fixation. Fifty-eight patients had postoperative CTs of the abdomen and pelvis with ePTFE and known transverse diameter of the implanted mesh. The prosthesis was measured on the CT using the AquariusNet software program (TeraRecon, San Mateo, CA), which outlines the mesh and calculates the total length. Data were collected regarding the original mesh size, known linear dimension of mesh, seroma formation, and time interval since mesh implantation in months. The mean shrinkage rate was 6.7%. The duration of implantation ranged from 6 weeks to 78 months, with a median of 15 months. Seroma was seen in 8.6% (5) of patients. No relationship was identified between the percentage of shrinkage and the original mesh size (P = 0.78), duration of time implanted (P = 0.57), or seroma formation (P = 0.074). In 27.5% (16) of patients, no shrinkage of mesh was identified. Of the patients who did experience mesh shrinkage, the range of shrinkage was 2.6-25%. Our results are markedly different from animal studies and show that ePTFE has minimal shrinkage after LIVH repair. The use of transfascial sutures in addition to tack fixation may have an implication on the mesh contraction rates.

VENTRAL INCISIONAL HERNIAS

Ventral Incisional Hernias are a well known complication after abdominal surgery with a reported incidence of 10% - 20% and a recurrence rate of 30% - 50% after open suture repair and less than 10% after open mesh repair. Objectives: To compare the outcome of two different methods of open repair of VIH (i.e. Mesh versus Non-mesh or Suture Repair in terms of morbidity, complications and recurrence. Period: 11 years period (January 2000 – December 2010). Setting: Shaikh Zayed Hospital, Lahore. Patients & Methods: The total number of patients who underwent surgery for repair of VIH during the study period was 321.There were only 33 patients in Group A (simple suture/Keel repair) while Group B had 288 patients. The most common early postoperative complications seen in both the groups were wound seroma and infection. Post-operative respiratory insufficiency was more common in the obese. Chronic pain and feeling of foreign body was more frequently seen in the mesh group. On the other hand, recurrence rates were far greater in the suture repair group. The overall mortality in the whole series was 3 patients (0.93%). Conclusions: The rates of ventral incisional hernia recurrence and complications are significantly lower after open onlay mesh repair as compared to the open suture repair. However, these results require confirmation by prospective randomized clinical trials which should also include the results of laparoscopic ventral incisional hernia repair which is a new and emerging technique in Pakistan.

Continuous Ambulatory Peritoneal Dialysis After Intra-Abdominally Placed Synthetic Mesh for Ventral Hernia Repair

We present a unique experience with a patient who had undergone continuous ambulatory peritoneal dialysis (CAPD) after laparoscopic repair of ventral incisional hernia (LRVIH) with an expanded polytetrafluoroethylene (e-PTFE) mesh (DualMesh(®); WL Gore) and who later suffered from multiple episodes of CAPD-related peritonitis without any signs of mesh infection. A 48-year-old man with an open abdominal aortic reconstruction in 1994 for occlusive arterial disease presented with an incisional ventral hernia. He underwent LRVIH using an e-PTFE mesh of 30×20 cm. Postoperatively, he developed renal failure. For various reasons, the only therapeutic option was CAPD. A CAPD-catheter was implanted via laparoscopy, taking care not to compromise the mesh that was completely covered with neoperitoneum. After 3 months of uneventful CAPD, he developed a bacterial peritonitis. Antibiotic treatment failed and the CAPD-catheter was removed. The mesh was left in place and the patient recovered. Later on another CAPD-catheter was implanted via laparoscopy and used for 10 months. Again he developed peritonitis from which he recovered after catheter removal. Mesh was left in place and remained uninfected, probably protected from intra-abdominal bacteria by the neoperitoneum. The risk of secondary infection of an intra-abdominal mesh seems to diminish largely after neoperitonealization of the mesh. CAPD seems possible in a patient with an intra-abdominal mesh when it is covered with neoperitoneum.

Preliminary Experience and Development of an Algorithm for the Optimal Use of the Laparoscopic Component Separation Technique for Myofascial Advancement During Ventral Incisional Hernia Repair

Component separation technique (CST) enables rectus abdominus medialization, but may cause wound complications. Few published outcomes exist involving laparoscopic CST. Our aim was to examine feasibility and outcomes involving open and laparoscopic (lap) CST during ventral incisional hernia repair (VIHR) and present an algorithm for ventral herniorrhaphy. Our design was a retrospective cohort study. Over 22 months, 28 patients underwent one of the following: (i) unilateral (U-) lap CST with open VIHR [n = 5], (ii) bilateral (B-) lap CST with open VIHR [n = 7], (iii) B-lap CST with lap VIHR [n = 8], or (iv) B-open CST with open VIHR [n = 8]. Indications for open VIHR included mesh removal, concomitant visceral procedure, wound revision, thin/ulcerated skin, abdominal wall tumor, frozen abdomen, and/or off-midline hernia. During open VIHR, CST was performed in the Ramirez fashion. Lap CST was performed before intraperitoneal access in lap VIHR and after retrorectus dissection in open VIHR. Patient surveillance consisted of clinical encounters and telephone interviews. Groups were similar regarding age, body mass index, American Society of Anesthesiologists classification, hernia width, operative time, and hospital stay. Six of the 20 patients who underwent open VIHR developed wound complications, and two required early reoperation. Four of the six with concomitant visceral procedures had wound complications. No laparoscopic VIHR patients had a wound complication. Based on 11 months' follow-up, one open VIHR patient has concern for recurrence. Laparoscopic CST is feasible during open and laparoscopic VIHR, but it appears most beneficial for wound healing after laparoscopic VIHR. During open VIHR, laparoscopic CST may not substantially reduce wound complications.

Laparoscopic ventral/incisional hernia repair: a single centre experience of 1,242 patients over a period of 13 years

Laparoscopic technique is now well established for ventral/incisional hernia repair. However several issues such as optimal fixation technique, occult hernias, management of inadvertent enterotomies, postoperative seromas and recurrence require appraisal. A single centre retrospective review of 1,242 patients between January 1992 and June 2005 is described. All patients had laparoscopic ventral/incisional hernia repair (LVIHR) following a standardised protocol by five consultants and fellows in a dedicated minimal access surgery unit of a tertiary care hospital. LVIHR was completed in 1,223 patients (98.5%). The average BMI was 32, mean defect size was 26.2 cm(2), mean operating time was 81 min and mean hospital stay was 1.9 days. The mean mesh to hernia ratio was 37.5. Occult hernias were observed in 203 (16.3%) patients and inadvertent enterotomies occurred in 21 (1.7%) patients. Mortality occurred in two patients, pulmonary embolism and cardiac dysrhythmia being the respective reasons. The most common sequel was early seroma formation (25%). Chronic pain occurred in 14.7% patients. Recurrence rate was 4.4%, which was associated with a higher BMI, use of staplers as fixation device, multiple defects and recurrent hernias. The mean follow up was 5.4 years; (range 2.4-10 years). The follow up rate was 78%. LVIHR leads to low recurrence rates and low rates of wound and mesh infection. Occult hernias are diagnosed and optimally treated laparoscopically. However, chronic pain remains an unresolved issue.

Computed tomographic measurements of mesh shrinkage after laparoscopic ventral incisional hernia repair with an expanded polytetrafluoroethylene mesh

The potential for shrinkage of intraperitoneally implanted meshes for laparoscopic repair of ventral and incisional hernia (LRVIH) remains a concern. Numerous experimental studies on this issue reported very inconsistent results. Expanded polytetrafluoroethylene (ePTFE) mesh has the unique property of being revealed by computed tomography (CT). We therefore conducted an analysis of CT findings in patients who had previously undergone LRVIH with an ePTFE mesh (DualMesh, WL Gore, Flagstaff, AZ, USA) in order to evaluate the shrinkage of implanted meshes. Of 656 LRVIH patients with DualMesh, all patients who subsequently underwent CT scanning were identified and only those with precisely known transverse diameter of implanted mesh and with CT scans made more than 3 months postoperatively were selected (n = 40). Two radiologists who were blinded to the size of the implanted mesh measured in consensus the maximal transverse diameter of the meshes by using the AquariusNET program (TeraRecon Inc., San Mateo, CA, USA). Mesh shrinkage was defined as the relative loss of transverse diameter as compared with the original transverse diameter of the mesh. The mean time from LRVIH to CT scan was 17.9 months (range 3-59 months). The mean shrinkage of the mesh was 7.5% (range 0-23.7%). For 11 patients (28%) there was no shrinkage at all. Shrinkage of 1-10% was found in 16 patients (40%), of 10-20% in 10 patients (25%), and of 20-24% in 3 patients (7.5%). No correlation was found regarding the elapsed time between LRVIH and CT, and shrinkage. There were two recurrences, one possibly related to shrinkage. Our observations indicate that shrinkage of DualMesh is remarkably lower than has been reported in experimental studies (8-51%). This study is the first to address the problem of shrinkage after intraperitoneal implantation of synthetic mesh in a clinical material.

Limited-conversion technique: a safe and viable alternative to conversion in laparoscopic ventral/incisional hernia repair

During laparoscopic ventral/incisional hernia repair (LVIHR), conversion to conventional (open) technique is required when safe adhesiolysis is not possible, incarcerated bowel in hernial sac cannot be reduced or for repair of iatrogenic enterotomies. A formal laparotomy in these circumstances entails significant morbidity due to factors such as wound infection, prolonged immobility, and longer hospital stay. During a period between 1994 and 2007, 1,503 LVIHRs were performed at our centre following a standardized protocol by five consultants and fellows. Out of these, 6 patients had a formal laparotomy in the initial part of our experience and 26 patients had a limited conversion to facilitate completion of LVIHR. We have devised the term "limited conversion" for the procedure wherein bowel reduction/adhesiolysis/enterotomy repair was performed through a small targeted skin incision. This was followed by laparoscopic placement of intraperitoneal mesh. Conversion to an open procedure was required in 32 (2.1%) out of 1,503 LVIHR procedures. Twenty-six patients underwent a limited conversion and completion of the repair by laparoscopy. All but one of these patients had intraperitoneal placement of mesh by laparoscopic route. The wound complication rate was 3.8% (one patient), the mean hospital stay was 2.1 days, and mean operative time was 124 min. Limited conversion offers a safe alternative to a formal laparotomy in patients with bowel incarcerated in hernial sacs or in patients requiring extensive bowel adhesiolysis. Patient morbidity is reduced due to the targeted skin incision whilst retaining several advantages of a minimal access approach viz. laparoscopic evaluation of the entire abdominal wall and placement of a large intraperitoneal prosthesis.

Repair of ventral incisional hernia: The design of a randomized trial to compare open and laparoscopic surgical techniques

The appearance of incisional hernia after laparotomy closure continues to be an important postoperative complication. Advances in anesthesia techniques, adequate prevention and treatment of infection during surgery, and the use of new suture materials have reduced the incidence of incisional hernia. Nevertheless, incisional hernia still occurs in 0.5% to 11% of all laparotomies performed. There are many different techniques currently in use for ventral incisional hernia (VIH) repair. Among these techniques, laparoscopic repair has been reported to be superior to open repair because of less pain, a lower recurrence rate, fewer complications, and earlier return to work. The lower rate of complications may be a major contributing factor to a reduced incidence of recurrence. However, laparoscopic repair requires expensive equipment and supplies, and it is not yet generally accepted. No conclusive randomized trial of sufficient size and power has been done to establish the “gold standard” for VIH repair, and surgeons are calling for proper evaluation. This randomized clinical trial conducted at 3 Veterans Affairs medical centers was designed to compare open VIH repair with the laparoscopic technique with respect to postoperative complications at 8 weeks, health-related quality of life, postoperative pain, time to return to normal activities, patient satisfaction, and recurrence rate of the hernia at 1 and 2 years. The study design calls for randomization of 314 men over a period of 32 months. This will allow ≥80% power to detect a 15% difference in complication rates between the 2 surgical procedures at 8 weeks. Randomization is stratified by hospital, whether the hernia is recurrent and whether the patient’s body mass index is ≥35 or <35. We report the design and beginning of a multicenter trial comparing open and laparoscopic VIH repair. When completed, this study will provide surgeons and their patients with information that will help guide their choice of surgical technique.

The feasibility of adopting laparoscopic incisional hernia repair in general surgery practice: early outcomes in an unselected series of patients.

A laparoscopic approach to incisional hernia repair has been shown to be safe and effective in selected patients. We report our early outcomes following laparoscopic ventral/incisional hernia repair (LVHR) in an unselected series of patients encountered in general surgery practice. All patients referred with incisional hernia were offered a laparoscopic repair using prosthetic mesh. Patients were not excluded from laparoscopic approach on the basis of age, previous surgery, defect size, intraperitoneal mesh, body mass index (BMI), comorbidities, or abdominal wall stomas. We followed 28 consecutive patients who underwent LVHR (17 primary, 11 recurrent hernias). Laparoscopic repair was completed in 27 patients with a mean operative time of 141.6 +/- 11.9 minutes. There were no intraoperative complications. The mean size of the abdominal wall defects was 153.4 +/- 27.5 cm and the mean mesh size was 349.2 +/- 59.1 cm. The mean hospital stay was 3.7 +/- 0.3 days. Nine patients developed large wound seromas; all spontaneously resolved. Our experience suggests that LVHR is feasible as a primary approach to most incisional hernias encountered in general surgery practice.

Complications of laparoscopic incisional-ventral hernia repair: the experience of a single institution.

Laparoscopic incisional-ventral hernia repair (LIVH) is used with increasing frequency for the morbidly obese and for complex and recurrent hernias. The experience of a single institution with this technique is reviewed and the findings and complications are presented. Data were collected retrospectively for a single surgeon's series of patients undergoing LIVH at the institution described in this report. The review showed a complication rate of 15.2%, a recurrence rate of 2%, and a prosthetic infection rate of 2%. Patients with a body mass index greater than 30 cm/m2 accounted for 73% of the complications and made up 62.2% of the patients. The LIVH procedure may be safely performed with low complication and recurrence rates even for the obese, allowing ventral hernia repair to be performed safely with good results. The LIVH technique should be considered for the repair of all incisional and ventral hernias requiring repair with a mesh prosthesis.
