【Abstract】Objective To investigate the effects and advantages of laparoscopic hernioplasty for hernia. Methods From June 1995 to June 2005, 222 patients with hernia were treated with laparoscopy. Transabdominal preperitoneal hernia repair (TAPP) were performed in 166 patients. Totally extraperitoneal hernia repair(TEP) were performed in 25 patients. Closure of the internal orifice of hernia was performed in 21 patients. Furthermore, incisional hernia in 2 patients, diaphragmatic hernia in 1 patient and mesenteric hernia in 1 patient were performed by laparoscopic hernioplasty and 6 patients with hernia of oesophagus finestra performed hernioplasty combined collapse gastric fundus with laparoscopy. In this series 45 patients associated with other abdominal disease were simultaneously treated with laparoscopy. Results All cases were operated successfully. The span of operation reduration was 42.5 min 〔(10～180 min)〕. The average length of postoperative hospital stay were 4.6 days. There was one early failure owing to the use of too small a piece of mesh.Conclusion The results indicate that mesh repair of hernias is a satisfactory technique with a low recurrence rate and a low major complication rate.
Objective To investigate the application of transverse fascia in inguinal hernia repair. Methods In this study, 617 patients underwent inguinal hernia repair between January 1990 and December 2005 in our hospital were included, which were divided into two groups according to different operative ways: transverse fascia method group (n=337) and Bassini method group (n=280). Then intraoperative results, postoperative complications, and rehabilitated results of patients in two groups were compared. Results Compared with Bassini method group, the patients in transverse fascia method group did not show significant difference in operative time and blood loss during operation (Pgt;0.05). The differences of severe postoperative pain, testicular swelling, the time of the body’s restore for normal activities, and recurrence rate of patients between two groups were significant (Plt;0.05), while the difference of hematoma of scrotum and infection of incisional wound (Pgt;0.05). Conclusion The strengthening of posterior wall by transverse fascia and reconstruction of inner ring is a simple and effective method for inguinal hernia repair.
Objective To explore the method and effectiveness of laparoscopic bundled fastigiated mesh in repairing inguinal hernia. Methods Between January 2003 and December 2009, 1 215 patients (1 363 sides) with inguinal hernia were treated. There were 1 132 males (1 268 sides) and 83 females (95 sides), aged from 18 to 89 years (median, 58 years). The cases included 1 187 cases (1 329 sides) of primary hernia and 28 cases (34 sides) of recurrent hernia. There were indirect inguinal hernia in 728 cases (786 sides), direct inguinal hernia in 416 cases (499 sides), femoral hernia in 43 cases (45 sides), and unusual hernia in 28 cases (33 sides). According to the hernia classification criteria, there were 31 cases (38 sides) in type I, 683 cases (754 sides) of type II, 403 cases (452 sides) of type III, and 98 cases (119 sides) of type IV. The disease duration was 1 to 9 days with an average of 3.8 days. To repair the hernia, the bundled fastigiated mesh was patched through the internal inguinal ring and fixed on the internal inguinal fascia by three-point fixation. The mesh would be wrapped in the peritoneum by purse-string suture. Results The surgeries were performd successfully. The operative time ranged from 18-32 minutes (mean, 22 minutes). Postoperative tractional pain in the inguinal region occurred in 19 cases (21 sides), acute uroschesis in 8 cases, and far-end hernial sac effusion in 2 cases (2 sides); all were cured after symptomatic treatment. All incisions healed by first intention, and no complications of fever, infection, or hematoma occurred. A total of 1 095 cases (1 182 sides) were followed up 1 to 7 years (median, 3 years and 9 months). Five patients died of medical illnesses at 1-3 years after operation. Three cases recurred and then were cured by a second surgery. No intestinal adhesion or obstruction occurred. Conclusion The bundled fastigiated mesh in laparoscopic inguinal hernia repair has the advantages of minimal invasiveness, easy-to-operate, less complications, and lower recurrence rate.

OBJECTIVE: To investigate the effectiveness of polypropylene path (Prolene) in hernia prevention following harvesting of rectus abdominis is myocutaneous flap. METHODS: From November 1999 to October 2000, Prolene patches were applied in 26 cases to repair the anterior rectus sheath following harvesting free rectus abdominis myocutaneous flap. Data concerning each case included size of rectus flap, defect of rectus sheath, size of patch used, wound healing and complications. RESULTS: Prolene patch showed good biocompatibility with abdominal tissue. No foreign-body rejection occurred after operation. Seroma developed in 1 case, and was drained bedside without complication. All prolene patches healed well in the body during follow-up. Hernia formation and abdominal bulge were not observed. CONCLUSION: Prolene patch is a satisfactory material for repair of the anterior rectus sheath after harvesting free rectus abdominis myocutaneous flap.
Objective To prepare a new sirolimus drug-coated polypropylene (SRL-PP) mesh by grafting he sirolimus onto the surface of the polypropylene (PP) mesh via chemical reaction, and to apply the new mesh to animal experiment to explore its anti-adhesion properties.MethodsThe sirolimus was grafted onto the surface of the mesh by chemical reaction to prepare the SRL-PP mesh, which was compared with the PP mesh and the polyethylene glycol modified polypropylene (PEG-PP) mesh. The three groups of meshes were respectively characterized (infrared spectroscopy test, contact angle measurement), and their tensile property was measured. These meshes were implanted into the abdominal cavity of the rats respectively. The anti-adhesion properties of the new sirolimus drug-coated mesh was studied by intraperitoneal adhesion and histopathological change in rats.ResultsThe results of infrared spectrum analysis showed that there was a new absorption peak at the wavelength 1 643 cm–1 (amide group) of SRL-PP mesh, suggesting that sirolimus drug was successfully uploaded onto the surface of the mesh; the SRL-PP mesh was excellent in hydrophilicity, which provided a favorable condition for the growth of peritoneal mesothelial cells. There was no significant difference in mechanical properties between SRL-PP mesh and PP mesh or PEG-PP mesh, which provided a good mechanical guarantee for clinical application. The degree of abdominal adhesion in SRL-PP mesh group (1.00±0.58) was significantly lower than that in PP mesh group (5.17±0.69) and PEG-PP mesh group (4.00±0.58), and the tD value between SRL-PP mesh group and PP mesh group was 2.76 (P<0.05). The number of inflammatory cells and the expression of inflammatory cytokines in the adhesion tissue in SRL-PP mesh group were significantly lower than those in PP mesh group and PEG-PP mesh group.ConclusionsThe sirolimus is successfully loaded onto the surface in the PP mesh by chemical reaction. Animal experiment shows that the sirolimus drug-coated mesh can significantly reduce the abdominal adhesion of the rats, which provides a basis for clinical trial and application.
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.
To summarize the therapeutic method and effectiveness of parastomal hernia repair in situ with sublay methods. Methods Between February 2003 and May 2009, 34 patients with parastoma hernia were treated with Sublay methods using primary midl ine incision approach and polypropylene patch. There were 23 males and 11 females withan average age of 58.4 years (range, 43-78 years). The disease duration was 1 to 17 years (mean, 4.7 years). Of 34 patients, 6 had recurrent parastoma hernia. The diameter of hernia ring was 5-12 cm (mean, 7.2 cm). Results Sublay technique repair was successfully performed in all patients. The operative time was 96-160 minutes (mean, 116 minutes). The gastric tube was pulled out 12 hours to 5 days (mean, 3 days) after operation. The drainage tube was taken out at 2-7 days (mean, 4 days) after operation. The postoperative hospital ization time was 7 to 15 days (mean, 9 days). And the incisions of 32 patients healed by first intention. Incisional fat l iquefaction occurred in 1 case and infection in 1 case, and their incisions healed after dressing change. Seroma at the upper of the patch occurred in 7 patients and was cured by 2 to 3 times of percutaneous puncture and local pressure. Thirty-two patients were followed up 6-75 months (mean, 32 months). No chronic pain, lumping sensation, or local expansion in wound area occurred. Two recurrences occurred 3 months and 7 months after operation, respectively, and patients restored after expectant treatment or re-operation. Conclusion The in situ Sublay methods using primary midl ine incision approach and nonabsorbable patch is a feasible and safe method for parastomal hernia repair.
