MethodsThe literatures in recent years on the etiological factor,pathology,epidemiology, diagnosis and therapeusis were reviewed and summarized. ResultsThe abdominal incisional hernia is a serious complication of abdominal operation which affect the patient’s quality of life severely. The etiological factors and treatments were complex. Conclusion Prophylaxis of abdominal incisional hernia is important. The tension free hernioplasty using synthetic materials is very popular and effective.
腹壁巨大切口疝的修补是很困难的手术，在一些特殊的病例中，由于患者的全身情况严重恶化使得切口疝无法修补，如年老、病态性肥胖及呼吸功能严重紊乱的患者。近年来，随着生物材料在疝和腹壁外科的广泛应用，对巨大腹壁切口疝的治疗已取得了明显进展。
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.
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 repair the huge incisional hernia of abdominal wall, a new surgical method was introduced. METHODS Eight cases of huge ventral incisional hernia, developed in 3 months to 12 months after operation, were treated in this new method with the defects ranged from 8 cm x 4 cm to 12 cm x 6 cm. RESULTS They were followed up for 6 months to 18 months after operation. The clinical results showed that all of the 8 cases recovered satisfactorily without recurrence. CONCLUSION The new method was recommendable for its advantages of easier manipulation, shortened time, no tissue reaction and less tissue trauma from operation.
The soft-tissue-cutaneous flap adjacent to the abdominal incisional hernia was ultilized to repair huge hernia in 6 cases with success. Patients were followed up for 2y7 years without recurrence. The operative planning, the technique and the matters needing attention were introduced in details. The soft tissues and skin adjacent to hernia used for repair was easy to obtain and a simple technique. The adoption of this operation in hospitals at the grassroots level was feasible.
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.
