ObjectiveTo investigate the surgical skills and clinical effects of the laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair in treatment of recurrent inguinal hernia with plug prefix mesh. MethodsThe clinical data such as operation time, intraoperative blood loss, postoperative hospital stay, and postoperative complications of 87 patients with recurrent inguinal hernia reoperated in laparoscopic TAPP after inguinal hernioplasty with plug prefix mesh (recurrent hernia group), in the Department of Gastroenterology and Hernia surgery of the First Affiliated Hospital of Kunming Medical University from January 2011 to December 2013, were retrospectively analyzed, which were compared with the 834 incipient inguinal hernia patients operated first by TAPP (incipient hernia group) at the same time. ResultsThe operations were completed successfully in all of the 921 patients without conversion to open surgery. The operation time and intraoperative blood loss in the recurrent hernia group were significantly more than those in the incipient hernia group (P=0.000, P=0.000), the postoperative hospital stay had no signifcant difference between two groups (P=0.057). No recurrences were observed in the recurrent hernia group and incipient hernia group for following-up of (31±4) months and (28±6) months, respectively. Compared with the incipient hernia group, the rates of postoperative pain on day 30 and seroma on day 1 and 3 were higher in the recurrent hernia group (P=0.001, P=0.040, P=0.003, respectively). There were no severe complications such as collateral damage, foreign body sensation, incision infection, intestinal obstruction and so on in the two groups. ConclusionsThe laparoscopic TAPP inguinal hernia repair is safe and effective for patients with recurrent inguinal hernia with plug prefix mesh. More skills are required to reduce the complications. The operation time and intraoperative blood loss in reoperated patients with recurrent inguinal hernia are more than those in patients with incipient inguinal hernia. The rates of seroma on day 1 and 3 are also higher.
ObjectiveTo compare the clinical efficacy of abdominal preperitoneal laparoscopic hernia repair with 3DMax patch and plain film for treatment of inguinal hernia. MethodsThe clinical and follow-up survey data of 120 patients with inguinal hernia in The Second Affiliated Hospital of Harbin Medical University, between January 2009 and May 2014, which were treated by laparoscopic transabdominal preperitoneal repair (TAPP) were retrospectively analyzed. One hundred and twenty cases were divided into two groups:plain film group (45 cases) and 3DMax group (75 cases) according to the intraoperative use of different patchs. The patches of 3DMax group were not fixed, the patches of plain film group were fixed with metal nails. The postoperative clinical effect of two groups were analyzed. ResultsThe operative time, intraoperative blood loss, and postoperative hospitalization days of two groups were no statistical significance (P > 0.05). The postoperative off bed activity time of patients in 3DMax group and plain film group was (20.2±8.1) h and (26.3±9.2) h, respectively, the average off bed activity time in 3DMax group was significantly earlier than that in plain film group (P=0.041). The material expenses and hospitalization expenses of the 3DMax group were significantly lower than those of the plain film group (P=0.001, P=0.038). The incidence of foreign body sensation of inguinal region in 1, 3, and 9 months after operation of 3DMax group were lower than those of plain film group (P=0.045). The VAS score in 1 and 3 months after operation of 3DMax group were lower than those of plain film group (P < 0.05), but there was no statistically significant in 6 months after operation of 2 groups (P > 0.05). There was no recurrence case in two groups. ConclusionsThe use of 3DMax patch in laparoscopic TAPP operation have more simple operation, hospitalization expenses decreased, recovery faster, postoperative inguinal nerve pain and foreign body sensation more lighter, and complications more less. It is worthy of clinical popularization and Application.
Objective To investigate the clinical effect of free forearm flap and titanium mesh in repairing maxillary defects. Methods From January 2002 to November 2002,partial maxillectomy or maxillectomy wereperformed in 3 patients with maxillary gingival carcinoma, in 1 patient with palatine mucoepicermoid carcinoma and in 1 patient with maxillary sinus carcinoma. Maxillary defects were reconstructed withfree forearm flaps ranging from 4 cm×5 cm to 6 cm×7 cm and titanium mesh.The effect was estimated by clinical examination, CT and nasopharyngoscope. Results Five cases were followed up 515 months. All the flaps were alive. Facial, alveolar process and palatal contours were restored well. Epithelium was found on the nostril surface of the titanium mesh. The functions of speech and chew were restored well. Conclusion A combination of the free forearm flap and titanium mesh is an ideal method in reconstruction of maxillary defects.
Objective To study the superiority and efficiency of total peritoneum intraperitoneal onlay mesh (TPIPOM) in laparoscopic inguinal hernioplasty. Methods One hundred and five cases of laparoscopic inguinal hernioplasty with TPIPOM and 34 cases of inguinal hernioplasty with trans-abdominal preperitoneal laparoscopic mesh repair (TAPP) were performed from January 2002 to August 2005. Perioperative data and follow-up results were collected and compared in two groups. Results The laparoscopic hernioplasty was successfully performed in all patients. The total operation time, hospital stay, average off-bed time, duration of pain in TPIPOM group were significant shorter than those in TAPP group 〔(30.8±10.3) min vs (68.4±22.4) min, (3.8±1.3) d vs (4.3±1.5) d, (1.2±0.5) d vs (1.8±0.7) d, (1.0±0.5) d vs (1.6±0.9) d, respectively〕, P＜0.01, the total hospital cost was RMB 5 000.8±800.5 in TPIPOM group and that was RMB 8 000.5±950.6 in TAPP group (P＜0.01). No significant scrotal edema was observed postoperatively and no recurrence reported during (18.6±8.9) months follow-up in both groups. Conclusion Laparoscopic inguinal hernioplasty with TPIPOM is safe and efficacy with advantages of mini-invasion, simple procedures, shorter operation time, no complications and better recovery.
Objective To investigate the effectiveness of laparoscopic Y-shaped polypropylene mesh in the treatment of uterine and vaginal vault prolapse. Methods Between June 2010 and December 2012, 24 patients with uterine and vaginal vault prolapse were treated by laparoscopic pelvic reconstruction (vagina and uterus-sacral fixation) with Y-shaped polypropylene mesh. The age of patients was 35-60 years (mean, 48.6 years). The disease duration was 2-8 years (mean, 5 years). According to the pelvic organ prolapse quatitative (POP-Q) classification by International Continence Society (ICS), 16 cases were classified as uterine prolapsed degree II and 8 cases as degree III; 15 cases were classified as vaginal prolapse degree I, 7 cases as degree II, and 2 cases as degree III. All patients received postoperative follow-up regularly. Subjective evaluation was done based on prolapse quality of life questionnaire (P-QOL), and objective evaluation based on POP-Q classification. Results All the patients were operated successfully. The operation time was 22-68 minutes (mean, 33 minutes); the blood loss was 30-80 mL (mean, 51 mL); the indwelling urethral catheter remain was 3-7 days (mean, 4 days); and the hospitalization days were 4-9 days (mean, 6.8 days). Twenty-four patients were followed up 3-12 months (mean, 9 months), of whom, 2 were followed up less than 6 months. All patients had normal urination after withdrawal of urethral catheter, and the residual urine volume was in normal range. No patients had mesh erosion and discomfort during sex, vaginal and anal bearing down. The P-QOL scores at 3, 6, and 12 months after operation were significantly improved when compared with the preoperative value (P lt; 0.05); but there was no significant difference among 3, 6, and 12 months after operation (P gt; 0.05). The postoperative POP-Q classification was degree 0 in 19 cases and degree I in 3 cases, and the objective cure rate was 91.7%. No recurrence was found during follow-up. Conclusion Laparoscopic Y-shaped polypropylene mesh for treatment of uterine and vaginal vault prolapse is a safe and effective method, especially applicable to preserve the uterus, and higher requirements of sexual life of patients.
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 investigate the effectiveness of repair procedure using biological mesh with Onlay-Reinforce technique in patients with perineal hernia. MethodsBetween January 2005 and December 2012, 9 patients with perineal hernia after laparoscopic abdominoperineal resection for rectal cancer (Miles operation) were treated. There were 3males and 6 females with a mean age of 70 years (range, 61-78 years). The disease duration was 1-9 months (mean, 4.5 months). The most beginning symptom was distending pain in perineal region, and then reducible mass was found without bowel incarceration. All patients underwent hernia repair using biological mesh with Onlay-Reinforce technique through original perineal incision. ResultsThe hernial size was 9.8-20.5 cm2 (mean, 16.0 cm2); the size of biological mesh was 58-80 cm2 (mean, 70.2 cm2); and the intraoperative blood loss was 10-80 mL (mean, 50.5 mL). All of the patients underwent repair operation successfully. The operation time was 45-90 minutes (mean, 60.6 minutes); and the hospitalization time was 4-7 days (mean, 5.9 days). One patient had urine retention, which was relieved after 7 days indwelling catheter. All the wounds healed by first intention without infection. The patients were followed up 14.5-60.7 months (mean, 37.8months). No chronic pain, obvious foreign body sensation, or hernia recurrence developed. ConclusionUse of biological mesh with Onlay-Reinforce technique for the repair of perineal hernia after Miles operation is safe and effective.
ObjectiveTo summarize the surgical experience of perineal hernia (PH) repairment after a laparoscopic abdominoperineal resection (APR) with synthetic mesh.MethodsThe clinical data of 4 cases of PH after APR from 2009 to 2015 underwent surgery were analyzed retrospectively. We applied synthetic mesh for the reconstruction of the pelvic floor.ResultsAll of the 4 cases recovered smoothly, with no complication happened. The blood loss during the operation was 50–100 mL, the operative time was 1.0–1.5 hours, the postoperative time of getting out of bed was delayed to 5–7 days after the operation and discharged after 10–14 days. Patients were advised to use transperineal bandages or rigid underpants to lift up the perineum to reduce tension after discharge. No recurrence of perineal hernia or the tumor was found on physical examination and abdominal pelvic CT scan during the 24-month follow-up.ConclusionsIt brings better effect and less trauma after the operation by using transperineal repair of PH with synthetic mesh. We suggest that this technique should probably be the first choice for treating an uncomplicated PH that occurs after a laparoscopic APR.
Test of tissue tolerance to domastic prosthetic materials (carbon fiber mesh, siliconized velvet, silk cloth and dacron cloth) as a subcutaneos transplant was performed in the adcominal wall of rabbit. These implants and their surroundding tissues were excied for studies at second , fourth, eighth and the twelfth weeks after operation. Ratio of fibroblast count to inflammatory cells count which is a common parameter of tissue tolerance was calculated in these four groups. The result shows that fibroblastic cell reaction elicited by carbon fiber mesh is the greates among the four prosthetic materials, the second one is dasron cloth. The inflammatory cell reaction elicited by silk is the greatest among the four materials, the second is carbon fiber mesh, and the dacron cloth the least. Tissure tolerance of dacron cloth is the best in the four prosthetic materials for implantation while sick is the worst.
ObjectiveTo compare the efficiency of total extraperitoneal inguinal herniorrhaphy with laparoscopic technique using an innovative self-gripping mesh and polypropylene mesh. MethodsThe clinical data of 142 cases of unilateral inguinal hernia who underwent total extraperitoneal prosthesis (TEP) in our hospital form June 2012 to March 2015 were retrospectively analyzed. the operation type was total extraperitoneal inguinal herniorrhaphy with laparoscopic technique. Depending on the kind of mesh, all patients were divided into two groups from the self-gripping mesh group (n=60) and the polypropylene mesh group (n=82). ResultsThere was no significant difference in the operation time, intraoperative blood loss, hospital stay, and The Visual Analogue Score of post-operative (at 12, 24, 48, and 72 hours after operation) between the 2 groups (P>0.05). On the post-operative complications, there was no significant difference in incidences of total complication, scrotal edema, seroma, bladder injury, vascular injury of abdominal, and urinary reten-tion too (P>0.05). All the patients were followed up for 3-36 months (the median time was 19-month), and no recurrence occurred during the follow-up period. ConclusionInnovative self-gripping mesh is safe and effective, and maybe a good direction of mesh for material development.
