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.

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 compare the efficacy of retromuscular repair of incisional hernia by using ProGrip self-gripping mesh and conventional polypropylene mesh. Methods A retrospective analysis was made on clinical data of 83 cases of incisional hernia between May 2012 and May 2016. Of 83 cases, ProGrip self-gripping mesh was used in 46 cases (self-gripping mesh group) and conventional polypropylene mesh (conventional mesh group) in 37 cases. There was no significant difference in gender, age, body mass index, types of incision hernia, hernia ring diameter, course of disease, and associated disease between 2 groups (P>0.05). The operative time, hospital stays, and visual analogue scale (VAS) were recorded and compared between 2 groups. Results The self-gripping mesh group was significantly lower than conventional mesh group in operative time and hospital stays (t=2.977,P=0.004;t=2.270,P=0.026). Primary healing of incision was obtained in 2 groups, with no seroma and mesh infection. The VAS score of self-gripping mesh group was significantly lower than that of conventional mesh group at 24 hours, 7 days, and 30 days after operation (P<0.05). The follow-up time was 5-53 months (mean, 25.8 months) in 43 patients of self-gripping mesh group, and was 7-54 months (mean, 27.4 months) in 33 patients of conventional mesh group. No chronic pain or hernia recurrence was found in both groups during follow-up time. Conclusion It is a safe and feasible curative way to use ProGrip self-gripping mesh for retromuscular repair of incisional hernia as it can reduce operative time, hospital stays, and postoperative pain.
Abstract: Objective To investigate the prognosis of residual shunt after surgical repair in infants. Methods We selected 407consecutive infant patients (255 males and 152 females) with venticular septal defects(VSD) between January 2008 and June 2008 in Shanghai Children’s Medical Center, Shanghai Jiaotong University. Of the patients, 273 were less than 1 yearold, 88 were 12 yearsold, and 46 were 23 years old. All of whom underwent surgical repair of the ventricular septal defect with autologous pericardial defect treated by glutaraldehyde. Results Of the 407 patients, 29 had residual ventricular septal defects, there was no significant difference among age groups in the rate of residual shunts （χ2=0.054，P=0.973）.Twentynine patients were followedup,and in the followup period of 1.5 months to 2 years postsurgery, 26 patients had spontaneous closure, while the other 3 patients did not heal. None of the patients needed reoperation. There was no significant difference amongage groups or type of ventricular septal defect in the rate of residual shunts (χ2=1.035，P=0.596). Conclusions Postsurgical residual ventricular septal defects smaller than 0.4 cm will close spontaneously in most infants.
Objective To summarize the therapeutic experiences of abdominal wall bulge repair with compound patch intraperitoneal placement. Methods From October 2005 to October 2008, intraperitoneal onlay mesh with compound patch applied in 7 patients with abdominal wall bulge, whose clinical data were analyzed retrospectively. Results All the procedures were performed successfully, including 5 open operation and 2 laparoscopic repair. The mean operation time was 85 min (ranged 68 to 130 min). After operation, 1 seroma formation and 1 hemorrhage in the thoracic cavity developed and were cured with the conservative therapy. Mean postoperative hospital stay was 9.5 d (ranged 8 to 16 d). There was no recurrence, infection, or prolonged pain during 1－4 years follow-up. Conclusion Abdominal wall bulge is caused by the weakness of abdominal wall muscle, and the intraperitoneal onlay mesh repair with compound patch is an appropriate therapy.
ObjectiveTo evaluate the feasibility of using acellular bovine pericardium as a viable tissue engineering vascular patch.MethodsFresh bovine pericardium was treated by enzyme detergent cell extraction, then they were used as vascular patches, ovine jugular vein segments were harvested, separated into endothelial and myofibroblast cells, expanded in cell culture, sequentially seeded onto acellular bovine pericardium patches (3cm×3cm). After 7 days of in vitro culture, the autologous cell/patches as experimental group ( n =5) were used to replace partial pulmonary artery wall. Animals were sacrificed at 4, 6, 8, 12 and 24 weeks. The acellular bovine pericardium patches without autologous cells were used as control group ( n =3). Animals were sacrificed at intervals of 4, 12 and 24 weeks. Explanted patches were evaluated by macroscopic and histologic examinations, assayed for calcium, elastin and collagen content.ResultsAll animals were survived without complications of thrombosis and aneurysm before sacrificed; there was no significant difference in calcium content in two groups; elastin ratio assay showed progressive increase over 4 to 24 weeks, similar to normal pulmonary artery wall, suggesting an ongoing tissue remodeling.ConclusionThe acellular bovine pericardium patch with or without autologous cell seeded to a certain extent can be changed into viable vascular wall tissue after being used to replace partial ovine pulmonary artery wall.
