Project description:Incisional hernias remain a surgical challenge when balancing surgical morbidity, functional restoration, and risk of recurrence. Laparoscopic intraperitoneal onlay mesh (IPOM) placement reduces postoperative wound infections and allows fast patient recovery. Yet, current IPOM techniques do not achieve closure of the midline hernia gap, thereby increasing the risk of persistent mesh bulging with poor abdominal wall function. We propose a novel triple-step hernia repair technique that includes tension-free midline reconstruction. It is achieved through laparoscopic dorsal component separation and laparoscopic suture closure of the midline with a 1.0 polydioxanone suture sling. Combining dorsal abdominal wall component separation, a midline closure with adequate suture strength, and IPOM reinforcement merges the benefits of open and laparoscopic hernia repair. This triple-step technique allows static and functional laparoscopic abdominal wall reconstruction.

Project description:ObjectiveIncisional hernia is a significant problem after laparotomy, and there is still no consensus on an ideal treatment method. The aim of this study was to compare the results of onlay and sublay mesh repair techniques.Material and methodsIn this randomized prospective trial, 100 patients were divided into two groups: onlay and sublay groups. Recurrences were evaluated by performing a physical examination.ResultsThe median follow-up was 37.1 (26.6 to 46.5) months. In the onlay group, the mean operation time was significantly shorter. However, in terms of postoperative pain and wound complications, the sublay group had significantly better results. The recurrence rates were found to be similar in both groups (6% in the onlay group and 2% in the sublay group).ConclusionIn the treatment of incisional hernia, sublay mesh repair is superior to onlay mesh repair in terms of postoperative pain and wound complications. Both techniques have similar recurrence rates.

Project description:BackgroundIncisional hernia is a frequent complication after abdominal surgery. The aim of this study was to assess the efficacy of prophylactic mesh reinforcement (PMR) after midline laparotomy in reducing the incidence of incisional hernia.MethodsA meta-analysis was conducted following PRISMA guidelines. The primary outcome was the incidence of incisional hernia after follow-up of at least 12 months. Secondary outcomes were postoperative complications. Only RCTs were included. A random-effects model was used for the meta-analysis, and trial sequential analysis was conducted.ResultsTwelve RCTs were included, comprising 1815 patients. The incidence of incisional hernia was significantly lower after PMR compared with sutured closure (risk ratio (RR) 0·35, 95 per cent c.i. 0·21 to 0·57; P < 0·001). Both onlay (RR 0·26, 0·11 to 0·67; P = 0·005) and retromuscular (RR 0·28, 0·10 to 0·82; P = 0·02) PMR led to a significant reduction in the rate of incisional hernia. The occurrence of seroma was higher in patients who had onlay PMR (RR 2·23, 1·10 to 4·52; P = 0·03). PMR did not result in an increased rate of surgical-site infection.ConclusionPMR of a midline laparotomy using an onlay or retromuscular technique leads to a significant reduction in the rate of incisional hernia in high-risk patients. Individual risk factors should be taken into account to select patients who will benefit most. [Correction added on 19 February 2020, after first online publication: J.

Project description:IntroductionMesh fixation is an important step in incisional hernia repair. Weak fixation possibly results in postoperative pain, and even hernia recurrence. We innovated an auxiliary fixation approach, the magnet attraction technique (MAT), to achieve better mesh fixation. The purpose of this study was to evaluate the effect of MAT in intraperitoneal onlay mesh (IPOM) procedures for incisional hernia repair.MethodsHistorical patient records were analyzed according to the clinical data of 16 patients with incisional hernias. Among them, 5 patients have undergone IPOM repair procedures in combination with MAT to assist in mesh fixation. As a control, 11 patients treated with IPOM and mesh fixation via conventional suspension were included. The clinical data collected include patients' basic characteristics, intraoperative and postoperative conditions, and follow-up results in both groups.ResultsCompared with patients in the control group, patients in the MAT group were found to suffer from a larger hernia ring diameter and longer surgical duration, but shorter hospitalization length on average. And most importantly, no complication has been reported in the MAT group.ConclusionMAT in IPOM operation was regarded as a feasible and safe technique for patients suffering from incisional hernias.

Project description:Ventral hernias pose a prevalent challenge in abdominal wall surgery, with ongoing advancements in repair techniques designed to enhance patient outcomes. This study evaluates the efficacy, safety, and socio-economic impact of Totally Extraperitoneal Sublay Repair (TES) versus Laparoscopic Intraperitoneal Onlay Mesh Repair (IPOM) for small to medium-sized ventral hernias, with a particular focus on postoperative quality of life and patient satisfaction. A retrospective cohort study was conducted, encompassing 125 patients who underwent ventral hernia repair between May 2018 and November 2023. The cohort included 55 patients treated with TES and 70 with Laparoscopic IPOM. Baseline characteristics, including age, gender, BMI, operative time, postoperative pain, hospitalization costs, and patient satisfaction score, were compared. Postoperative quality of life was evaluated through outpatient visits or telephone follow-ups. The propensity score matching (PSM) technique was applied in a 1:1 ratio to balance the significant differences in general characteristics between the two groups. Out of 125 patients, 70 cases were successfully matched using the PSM method, resulting in 35 cases in each group. The baseline characteristics of patients in groups were well-matched (P > 0.05). The TES group exhibited a significantly longer operative duration (P < 0.001); however, this group also experienced markedly reduced postoperative pain, decreased hospitalization costs, and diminished postoperative drainage (all P < 0.001). The length of hospital stay and the incidence of long-term complications were similar between the two groups. Follow-up evaluations at 3 and 6 months showed a significantly improved quality of life and higher patient satisfaction in the TES group. Both TES and IPOM demonstrate comparable safety and efficacy in the repair of ventral hernias. Although TES is associated with a longer operative duration, it provides significant advantages in postoperative quality of life, patient satisfaction, and cost-effectiveness, thereby supporting its broader clinical adoption.

Project description:BackgroundProphylactic mesh augmentation (PMA) is an effective technique utilized to reduce the risk of incisional hernia. This study analyzes the biomechanical characteristics of a mesh-reinforced closure and evaluates a novel prophylactic mesh implantation device (SafeClose Roller System; SRS).Materials and methodsA total of eight senior-level general surgery trainees (≥4 years of training) from the University of Pennsylvania Health System participated in the study. Biomechanical strength, mesh stiffness, mesh uniformity, and time efficiency for fixation were compared among hand-sewn mesh fixation, SRS mesh fixation and a no-mesh fixation control. Porcine abdominal wall specimens served as simulated laparotomy models.ResultsBiomechanical load strength was significantly higher for mesh reinforced repairs (P = 0.009). The SRS resulted in a stronger biomechanical force than hand-sewn mesh (21.2 N stronger, P = 0.317), with more uniform mesh placement (P < 0.01), faster time of fixation (P < 0.001) and with less discrete hand-movements (P < 0.001).ConclusionsMesh reinforcement for incisional reinforcement has a significant impact on the strength of the closure. The utilization of a mesh-application system has the potential to amplify the advantages of mesh reinforcement by providing efficiency and consistency to fixation methods, with similar biomechanical strength to hand-sewn mesh. Additional in vivo analysis and randomized controlled trials are needed to further assess clinical efficacy.

Project description:Endoscopic techniques have been widely used in ventral hernia surgery. Totally visceral sac separation (TVS) is a new concept proposed for hernia repair in recent years. The aim of this study was to contrast the postoperative results of TVS with the widely used method of Laparoscopic intraperitoneal onlay mesh plus repair (IPOM plus) for incisional hernias. The retrospective comparison analysis of 38 IPOM plus and 34 TVS was conducted during the time period between December 2019 and June 2022. For both two groups, baseline characteristics, surgical records, postoperative information, and quality of life outcomes utilizing the Carolina's Comfort Scale were collected and analyzed. There were no differences between the methods of TVS and IPOM plus among the baseline characteristics. It showed the operative time in TVS group with the mean time of 213.4 min was significantly longer than that in IPOM plus group with the mean time of 182.9 min (P = 0.010). The postoperative length of stay in TVS group was 6.2 days, which was significantly shorter than IPOM plus group with the mean time of 4.8 days (P = 0.011). The medical expenses was significantly smaller in TVS group than that in IPOM plus group (P < 0.001). The quality of life scores of TVS were significant better than IPOM plus at one week, one month and six months. Besides, both TVS and IPOM plus have very few complications. TVS approach for incisional hernias is secure, effective, and valuable. It has shorter postoperative length of stay, higher quality of life, longer operative time, smaller medical expenses, and approximate complications compared with IPOM plus procedure. Our results have a greater contribution to the application and popularization of TVS technique.

Project description:BackgroundIncisional hernia is the most frequently seen long term complication after laparotomy causing much morbidity and even mortality. The overall incidence remains 11-20%, despite studies attempting to optimize closing techniques. Two patient groups, patients with abdominal aortic aneurysm and obese patients, have a risk for incisional hernia after laparotomy of more than 30%. These patients might benefit from mesh augmented midline closure as a means to reduce incisional hernia incidence.Methods/designThe PRImary Mesh Closure of Abdominal Midline Wound (PRIMA) trial is a double-blinded international multicenter randomized controlled trial comparing running slowly absorbable suture closure with the same closure augmented with a sublay or onlay mesh. Primary endpoint will be incisional hernia incidence 2 years postoperatively. Secondary outcomes will be postoperative complications, pain, quality of life and cost effectiveness.A total of 460 patients will be included in three arms of the study and randomized between running suture closure, onlay mesh closure or sublay mesh closure. Follow-up will be at 1, 3, 12 and 24 months with ultrasound imaging performed at 6 and 24 months to objectify the presence of incisional hernia. Patients, investigators and radiologists will be blinded throughout the whole follow up.DisccusionThe use of prosthetic mesh has proven effective and safe in incisional hernia surgery however its use in a prophylactic manner has yet to be properly investigated. The PRIMA trial will provide level 1b evidence whether mesh augmented midline abdominal closure reduces incisional hernia incidence in high risk groups.Trial registrationClinical trial.gov NCT00761475.
