  • EFFECTIVENESS ANALYSIS OF LAPAROSCOPIC REPAIR OF PARASTOMAL HERNIA USING CK Parastomal PATCH

    Objective To summarize the surgical technique and the effectiveness of CK Parastomal patch in laparoscopic repair of parastomal hernia. Methods The cl inical data were retrospectively analysed from 24 patients who received laparoscopic repair of parastomal hernia using CK Parastomal patch between June 2006 and March 2010. There were 15 males and 9 females with a median age of 55 years (range, 47-80 years). Among them, 19 patients were with colon parastomalhernia in the left lower quadrant and 5 patients with ileum parastomal hernia in the right lower quadrant. The parastomal hernia duration was 1 to 4 years (mean, 2.4 years). The maximal diameter of the hernia ring was 3 to 7 cm (mean, 5.2 cm). All patients did not receive hernia repair. Results Laparoscopic repair of parastomal hernia was successfully performed in 18 cases, and open repair was used in 6 cases because of extensive adhesion. The average operating time was 121 minutes (range, 78 to 178 minutes). All wounds healed by first intention. Wound seroma occurred in 8 cases at 3 to 7 days after operation and disappeared by aspiration. Eleven patients complained of pain in the operative area within 1 month after operation and it disappeared without intervention. All patients were followed up 6 to 39 months (mean, 27 months). One recurrence occurred at 3 months after operation, and no recurrence occurred in the other patients. Conclusion Laparoscopic repair of parastomal hernia using CK Parastomal patch is a safe and feasible procedure with a satisfactory short-term effectiveness, but the long-term effectiveness should be further observed.

    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.

  • PREVENTIVE EFFECT OF POLYPROPYLENE MESH BONDED NORVANCOMYCIN SLOW-RELEASE MICROSPHERE ON STAPHYLOCOCCUS AUREUS INFECTION OF INCISIONAL HERNIA REPAIR MODEL

    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.
