Objective To summarize the surgical technique and curative effect of laparoscopic repair for suprapubic incisional hernia using composite patch. Methods The clinical data of 25 cases performed laparoscopic repair of suprapubic incisional hernia using composite patch from March 2007 to October 2010 were reviewed retrospectively. There were 13 males and 12 females， and aged 35-83 years （median age was 52 years）. Among them 2 patients were recurrences. The distance between the lower margin of hernia defect and pubic arc was less than 5 cm. The composite patch was fixed to the abdominal wall using spiral tacks （Protack） in direct vision. The lower margin of the patch was lower to the pubic arc in 2 cm， and to be fixed to the pubic arc and bilateral pectineal ligament， and it should be extended. Results Laparoscopic repair were successfully performed in all patients without convert to open repair. The max diameter of the hernia ring was 6.1-12.5cm and the average was 9.5 cm. The average operating time was 128 min （ranging from 90 to 180 min）. And the total complication rate was 28% （7/25）， including bladder damage during operation in 1 case， wound seroma upon the patch in 4 cases and cured by aspiration， pain in the operative area and disappeared within one month without intervention in 1 case. Twenty-two patients were followed-up with a follow-up rate of 88%. During a follow-up range of 6-48 months（average 30 months）， one case recurrence occurred in 2 months after the repair with the recurrent rate of 4%. Conclusions Laparoscopic repair of suprapubic incisional hernia is a safe and feasible technique， and the patch should cover and exceed the margin of the defect for 5 cm in all direction. The lower margin of the patch should be fixed to the bilateral pectineal ligament so as to strengthen the fix， and lower the recurrence rate.
Objective Surgical repair for giant lower ventral hernia is facing challenge owing to enormous tissue defect and the critical structures of pubis and il iac vessels. To investigate the method and curative effect of intraperitoneal onlay mesh (IPOM) combined with Sublay for compound repair of giant lower ventral hernia. Methods Between November 2008 and August 2010, 26 patients with giant lower ventral hernia were treated. There were 15 males and 11 females with an averageage of 61 years (range, 36-85 years), including 11 cases of lower midl ine incisional hernia due to radical rectal procedures, 6 cases of Pfannenstiel incisional hernia due to radical uterectomy, and 9 cases of lower midl ine incisional hernia due to radical cystectomy. Of them, 11 patients underwent previous repair procedures. The mean time from hernia to admission was 8.5 years (range, 1-15 years). All hernias were defined as M3-4-5W3 according to classification criteria of Europe Hernia Society. The mean longest diameter was 17.5 cm (range, 13-21 cm) preoperatively. Before 2 weeks of operation, abdominal binder was tightened gradually until the contents of hernia sac were reduced totally, and then reconstruction of abdominal wall was performed with compound repair of IPOM and Sublay technique. Results All of compound repair procedures were performed successfully. The mean hernia size was 112.5 cm2 (range, 76.2-160.6 cm2); the mean polypropylene mesh size was 120.4 cm2 (range, 75.3-170.5 cm2); and the mean compound mesh size was 220.0 cm2 (range, 130.4-305.3 cm2). The mean operative time was 155.5 minutes (range, 105.0-195.0 minutes) and the mean postoperative hospital ization time were 12 days (range, 7-16 days). Incisions healed by first intention; 4 seromas (15.4%) and 3 chronic pains (11.5%) occurred and were cured after symptomatic treatment. All patients were followed up 3-24 months (mean, 14.5 months). No recurrence and any other discomforts related to repair procedure occurred. Conclusion Compound repair of IPOM and Sublay is a safe and efficient surgical procedure for giant lower ventral hernia, owing to its characteristics of adequate patch overlap and low recurrence rate. Perioperative management and operative technology play the key role in the success of repair procedure.

ObjectiveTo explore the risk factors of recurrence of incisional hernia following incisional hernia tension-free repair. MethodsThe clinical data of 162 patients with incisional hernia underwent tension-free repair were retrospectively analyzed in this hospital from January 2005 to January 2011. The relationships of incisional hernia recur-rence to gender, age, body mass index, hernia size, abdominal wall defect site, preoperative chronic comorbidities, type of tension-free repair, operation time, and wound healing disorders were analyzed by univariate and multivariate analysis. ResultsOne hundred and sixty-two patients were followed up 7-70 months with mean 34.5 months. The rate of recur-rence following incisional hernia tension-free repair was 9.26% (15/162). The results of univariate analysis showed that recurrence following incisional hernia tension-free repair was associated with the age (P < 0.05), body mass index (P < 0.05), type of tension-free repair (P < 0.05), hernia size (P < 0.05), and wound healing disorders (P < 0.05). The results of multivariate logistic regression revealed that the body mass index, type of tension-free repair, hernia size, and wound healing disorders were the independent risk factors associated with recurrence following incisional hernia tension-free repair. Fifteen recurrent patients were reperformed successfully. There was no recurrence following up with an average 23 months. ConclusionsIt is necessary to become familiar with the risk factors for recurrence of incisional hernia in order to eliminate or decrease their effects on the positive outcome of incisional herniorrhaphy. The patients with fat, hernia ring bigger, incorrect opera-tion or wound healing disorders might be easy to relapse. Surgical approach should be individualized for recurrence.
Objective Mesh infection may occur after incisional hernia repair using prosthetic mesh. Preparation of antibiotics-bonded meshes to prevent infection is one of the solutions. To evaluate the anti-infection effect of polypropylene mesh bonded norvancomycin slow-release microsphere by preparing the rat model of incisional hernia repair contaminatedwith Staphylococcus aureus. Methods The norvancomycin slow-release microspheres were prepared by emulsion and solvent evaporation method and they were bonded to polypropylene mesh (50 mg/mesh). The appearance of the microspheres was observed using scanning electronic microscope (SEM). The content of norvancomycin in microspheres and the release rate of the norvancomycin in norvancomycin-bonded polypropylene mesh were detected using high performance l iquid chromatography method. The rat models of incisional hernia were developed in 40 healthy Sprague Dawley rats, aged 10-11 weeks and weighing 200-250 g. The rats were divided randomly into the experimental group (norvancomycin-bonded polypropylene mesh repair, n=20) and the control group (polypropylene mesh repair, n=20). And then the mesh was contaminated with Staphylococcus aureus. The wound heal ing was observed after operation. At 3 weeks after operation, the mesh and the tissue around the mesh were harvested to perform histological observation and to classify the inflammatory reaction degree. Results The norvancomycin microsphere had integrated appearance and smooth surface with uniform particle diameter, 64% of particlediameter at 60 to 100 μm, and the loading-capacity of norvancomycin was 19.79%. The norvancomycin-bonded polypropylene patch had well-distributed surface and the loading-capacity of norvancomycin was (7.90 ± 0.85) mg/cm2. The release time of norvancomycin in vitro could last above 28 days and the accumulative release rate was 72.6%. The rats of 2 groups all survived to experiment completion. Wound infection occurred in 2 rats of the experimental group (10%) and 20 rats of the control group (100%), showing significant difference (χ2=32.727 3, P=0.000 0). The inflammatory reaction in experimental group was not obvious, grade I in 16 rats and grade II in 4 rats, and numerous inflammatory cell infiltration occurred in the control group, grade II in 3 rats and grade III in 17 rats, showing significant difference (Z=32.314, P=0.000). Conclusion The polypropylene mesh bonded norvancomycin slow-release microsphere has definite anti-infection effect in rat model of incisional hernia repair contaminated by Staphylococcus aureus.

Objective To summarize the experiences and methods on reoperation of recurrent incisional hernia after mesh repair with prosthetic patch. Methods Sixteen patients who got reoperation from January 2007 to December 2010 because of recurrent incisional hernia after mesh repair were analyzed retrospectively. Results All patients received prosthetic patch repair for reoperation. Thirteen patients received new mesh repair accompanied with old mesh removal, repair conducted by suturing new mesh with old mesh together in two patients, and repair performed by new mesh overlapping the old mesh in one patient. All patients recovered with primary wound healing. Fluid upon the mesh occurred in 3 patients and cured by percutaneous puncture and pressure dressing. Postoperative hospital stay was 7 to 16 days and the average 9 days. The drainage was removed 2 to 7 days after operation and the average was 4 days. All the 16 patients were followed up. And during a follow-up range of 5 to 36 months and the average 20 months, there was slight foreign body sensation in one patient, no chronic pain in wound area occurred. And no abdominal wall hernia recurrence occurred. Conclusions Reoperation of recurrent incisional hernia after mesh repair need to consider the recurrent position, material of the previous mesh, and the previous surgical methods, and should select appropriate prosthetic patch and surgical procedure, then could gain satisfied results.
