ABSTRACT
Objectives:To investigate the clinical value of a novel non-crosslinked biological mesh in laparoscopic inguinal hernia repair.Methods:The prospective randomized controlled study was conducted. The clinical data of 50 adult patients with unilateral inguinal hernia who were admitted to 3 medical centers, including Ruijin Hospital of Shanghai Jiaotong University School of Medicine et al, from September 2019 to March 2020 were selected. Based on random number table, patients were divided into two groups. Patients using the novel non-crosslinked biological mesh in repair surgery were divided into the experiment group and patients using the lightweight, micro-porous, partially absorbable synthetic mesh in repair surgery were divided into the control group. Observation indicators: (1) grouping situations of the enrolled patients; (2) endpoint of the study. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted using the non-parameter rank sum test. Count data were described as absolute numbers and (or) persentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was conducted using the non-parameter rank sum test. Repeated measurement data were analyzed using the repeated ANOVA. Taking the recurrence rate of hernia as the basis of efficacy evaluation, according to the intention-to-treat analysis, the confidence interval method (Newcombe Wilson method) was used to conduct non-inferiority statistical analysis of the recurrence rate of hernia between the experiment group and the control group. If the upper limit of 95% confidence interval of the difference of recurrence rate of hernia between the experiment group and the control group is less than 10%, the experiment group is considered to be non-inferior to the control group. Results:(1) Grouping situations of the enrolled patients. A total of 50 adult patients with inguinal hernia were selected for eligibility. There were 44 males and 6 females, aged (60±15)years. All 50 patients were randomly divided into to the experiment group and the control group with 25 cases each. One patient in the control group was not followed up at postoperative month 2, and the rest of 49 patients completed all expected follow-up. No patient in the two groups fell off or were removed. (2) Endpoint of the study. ① The primary endpoint of study. The recurrence rate of hernia was 0 in the experiment group, versus 4%(1/25) in the control group, respectively, showing no significant difference between the two groups ( P>0.05). Results of non-inferiority statistical analysis showed that the 95% confidence interval of the difference of recurrence rate of hernia between the two groups was -19.54% to 9.72%, with the upper limit as 9.72%, which was less than 10%. ② The secondary endpoint of study. There were 2 patients in the control group occurred seroma at postoperative day 14, and none of the rest of patient in the two groups occurred seroma during the follow-up, showing no significant difference in the occurrence of seroma between the two groups ( P>0.05). There was 1 patient in the control group feeling discomfort or foreign body sensation in groin area at postoperative month 2, and none of the rest of patient in the two groups feeling discomfort or foreign body sensation in groin area during the follow-up, showing no significant difference in the feeling discomfort or foreign body sensation in groin area between the two groups ( P>0.05). There was no patient occurred surgical site infection in the experiment group, and there was 1 patient in the control group occurred postoperative skin infection, which had no relationship with mesh. There was no patient in both two groups occurred fever, anaphylaxis and patch related serious adverse reaction during the follow-up. The resting visual analogue scale score, active visual analogue scale score of patients at postoperative 2 days and postoperative 18 months were 0.44±1.00, 1.28±1.46 and 0, 0 in the experiment group, versus 0.40±0.76, 1.28±1.14 and 0.24±1.20, 0.44±1.29 in the control group, respectively. There was a significant difference in the time effect of postoperative active visual analogue scale score of patients between the two groups ( Ftime=10.19, P<0.05). The thickness of the novel non-crosslinked biological mesh before implantation was 0.5?0.7 mm. Two months after operation, results of B-ultrasonic examination in groin area of 10 patients from the experiment group showed a strong echo area at the patch implant area with a thickness as 2 mm. Conclusion:Application of novel non-crosslinked biological mesh in laparoscopic inguinal hernia repair is safe and effective.

ABSTRACT
Objective: To compare the morbidity of perineum-related complication between biological mesh and primary closure in closing pelvic floor defects following extralevator abdominoperineal excision (ELAPE). Methods: A literature search was performed in PubMed, Embase, Cochrane Library, Web of Science, Wanfang database, Chinese National Knowledge Infrastructure, VIP database, and China Biological Medicine database for published clinical researches on perineum-related complications following ELAPE between January 2007 and August 2020. Literature inclusion criteria: (1) study subjects: patients undergoing ELAPE with rectal cancers confirmed by colonoscopy pathological biopsy or surgical pathology; (2) study types: randomized controlled studies or observational studies comparing the postoperative perineum-related complications between the two groups (primary perineal closure and reconstruction with a biological mesh) following ELAPE; (3) intervention measures: biological mesh reconstruction used as the treatment group, and primary closure used as the control group; (4) outcome measures: the included literatures should at least include one of the following postoperative perineal complications: overall perineal wound complications, perineal wound infection, perineal wound dehiscence, perineal hernia, chronic sinus, chronic perineal pain (postoperative 12-month), urinary dysfunction and sexual dysfunction. Literature exclusion criteria: (1) data published repeatedly; (2) study with incomplete or wrong original data and unable to obtain original data. Two reviewers independently performed screening, data extraction and assessment on the quality of included studies. Review Manager 5.3 software was used for meta-analysis. The mobidities of perineum-related complications, including overall perineal wound (infection, dehiscence, hernia, chronic sinus) and perineal chronic pain (postoperative 12-month), were compared between the two pelvic floor reconstruction methods. Finally, publication bias was assessed, and sensitivity analysis was used to evaluate the stability of the results. Results: A total of five studies, including two randomized controlled studies and three observational controlled studies, with 650 patients (399 cases in the biological mesh group and 251 cases in primary closure group) were finally included. Compared with primary closure, biological mesh reconstruction had significantly lower ratio of perineal hernia (RR=0.37, 95%CI: 0.21-0.64, P<0.001). No significant differences in ratios of overall perineal wound complication, perineal wound infection, perineal wound dehiscence, perineal chronic sinus and perineal chronic pain (postoperative 12-month) were found between the two groups (all P>0.05). Conclusion: Compared with primary closure, pelvic floor reconstruction following ELAPE with biological mesh has the advantage of a lower incidence of perineal hernia.

ABSTRACT
OBJECTIVE: To analyze the reoperation method and effect of recurrent inguinal hernia in adolescents after operation. METHODS: The data of 9 adolescent(13 to 18 years old) inguinal hernia patients with recurrence after surgical treatment admitted in the first people's hospital of Foshan from January 2006 to December 2018 were analyzed retrospectively. The methods of previous operation, reoperation, size of internal ring, major postoperative complications and recurrence rate were collected. RESULTS: Among the 170 adolescent patients who underwent inguinal hernia surgery,there were 9 cases of recurrent indirect inguinal hernia(the previous operation method was high ligation of the internal ring), including 2 cases of open surgery and 7 cases of laparoscopic surgery. Of the 9 patients, 3 had multiple recurrences and 6 had first recurrence. The sizes of internal ring were 0.3 to 3.0 cm in the operation. Surgical methods: 4 cases were performed with laparoscopic high ligation of internal ring, with the sizes of internal ring ranging from 0.3 cm to 2.0 cm. Laparoscopic inguinal hernia mesh repair was performed in 5 patients(3 patients with multiple recurrences)with the sizes of internal ring ranging from 1.5 cm to 3.0 cm. During the follow-up period of 6 months to 10 years, no wound or mesh infection, 3 patients showed discomfort in the inguinal area, 2 patients had mesh repair and 1 patient had high ligation. Seroma appeared in 1 patient which was repaired by mesh. One case of recurrence which was mesh repair.CONCLUSION: The choice of surgical method for recurrent inguinal hernia in adolescents should be based on the previous surgical method, recurrence frequency and the presence of large internal ring defect or transverse abdominal fascia defect. Laparoscopic high ligation is recommended for patients with primary recurrence of small internal ring defect. For patients with multiple recurrence or large internal ring defect, mesh repair is recommended.
ABSTRACT
OBJECTIVE: To analyze the application value of biological mesh in inguinal hernia patients aged from 18 to44 years old. METHODS: The clinical data of 127 patients with inguinal hernia admitted from January 2013 to December 2018 in Huadong Hospital Affiliated to Fudan University were analyzed retrospectively. Through the abdominal transverse fascia reinforcement with biological mesh(tTRB), it was to observe indicators during perioperative and followup periods, to explore the application value and treatment experience of biological mesh in young patients with inguinal hernia. RESULTS: All the 127 cases were successfully completed. There were obvious pain in 3 cases and scrotal edema in 3 cases. No other patients were found to have obvious discomfort. All patients had no complications such as recurrence, chronic pain and infection after 3 to 12 months of follow-up. CONCLUSION: The rational use of biological mesh to repair young and middle-aged patients with inguinal hernia is effective. The advantage is that the effect of mesh minimize the impact on long-term quality of life in young patients. At the same time, the risk of postoperative infection and chronic pain is effectively reduced by reinforcement of transverse fascia with biological mesh, which is worthy of further study.
ABSTRACT
Adolescent is a special group which is still at the period of growth and development. Protecting reproductive function, reducing recurrence and chronic postoperative inguinal pain are the key points of treatment of inguinal hernia in adolescents. Although there are different surgical treatments for inguinal hernia in adolescents at present, the characteristics of biological mesh which can promote tissue regeneration and remodeling make them valuable for inguinal hernia repair in adolescents. Correct selection and implementation of biological mesh inguinal hernia repair are important to ensure the effect of adolescent inguinal hernia repair.
ABSTRACT
The adolescent inguinal hernia has particularity in modern surgical treatment. Because of in the stage of growth and development, it can not be used only for the inguinal hernia sac high ligation, nor can it be treated as an adult inguinal hernia with artificial synthesis material mesh.Therefore, there are still many disputes in adolescent inguinal hernia treatment. As a kind of absorbable material, biologic mesh can repair inguinal hernia defect and induce the growth of cells and fibrous tissue to repair the defect of the inguinal wall. It can be degraded and absorbed by the body after the repair of the defect by the proliferation of autologous tissue,which does not affect the growth and development of adolescents,and its advantages have been affirmed by more scholars. Biologic mesh has become an ideal choice for the repair of inguinal hernia in adolescents.
ABSTRACT
Objective To investigate the safety and efficacy of tension-free mesh repair in the treatment of incarcerated groin hernia,and to compare the outcome of biological mesh and polypropylene mesh repairment.Methods A retrospective study was conducted on 118 patients admitted from Jan 2013 to Dec 2017 receiving emergency incarcerated groin hernia repair in Beijing Chao-Yang Hospital.The incidence of surgical site infection (SSI),perioperative mortality,sepsis and ileus were compared.In the follow-up,the postoperative foreign body sensation,chronic pain,seroma/hematoma and recurrence were recorded.The outcome of different surgical procedures (with mesh/without mesh,biological mesh/polypropylene mesh,TAPP/Lichtenstein repair) were compared and analyzed.Results 14 cases received suture repair (group A),104 cases underwent TAPP (n=44) repair or Lichtenstein repair (n =60) with meshes,including 23 cases using biological mesh (group B) and 81 cases using polypropylene mesh (group C).After 20.5 months of follow-up (ranging from 6-65 months),3 cases in group A (21.4％) developed recurrence,the rate was significantly higher than that of group B (4.3％) and group C (0).The incidence of seroma/hematoma in group B was higher than that in group A (7.1％) and group C (7.4％).There were no significant differences between the 3 groups regarding the postoperative adverse events rate,SSI,mortality,sepsis and ileus (all P ＞ 0.05).Conclusions Tension-free mesh repair in the treatment of emergency incarcerated groin hernia is safe and effective,which can reduce the recurrence rate of hernia,without increasing the risk of infection.

ABSTRACT
Objective To investigate the application value of biological mesh in the pelvic floor reconstruction of extralevator abdominoperineal excision (ELAPE) for advanced low rectal cancer (RC).Methods The retrospective cohort study was conducted.The clinicopathological data of 228 patients with advanced low RC who underwent ELAPE in the Beijing Chaoyang Hospital of Capital Medical University between August 2008 and December 2016 were collected.Of 228 patients,174 using biological mesh closure and 54 using primary closure were respectively allocated into the biological mesh group and primary closure group.Observation indicators:(1)intra-and post-operative situations;(2) postoperative complications (including short-term and long-term complications);(3) follow-up and survival situations.Follow-up using outpatient examination and telephone interview was performed to detect postoperative long-term complications,tumor recurrence or metastasis and overall survival up to December,2017.Measurement data with normal distribution were represented as（ x） ±s,and comparison between groups was analyzed using the independent-sample t test.Measurement data with skewed distribution were described as M (range),and comparison between groups was analyzed using the nonparametric test.Comparisons of count data were evaluated by the chi-square test or Fisher exact probability.Results (1)Intra-and post-operative situations:all the patients underwent successful ELAPE.The perineal operation time,time of indwelling perineal drainage-tube and hospital expenses were respectively (60 ± 50)minutes,(11.6 ± 2.4) days,(57 781± 11 337) yuan in the biological mesh group and (50±21) minutes,(8.9± 1.7) days,(53 714± 13 395)yuan in the primary closure group,with statistically significant differences between groups (t =3.327,7.691,-2.203,P＜0.05).The total operation time and duration of postoperative hospital stay were respectively (242±53) minutes,(13.0±5.0) days in the biological mesh group and (228±51) minutes,(12.0±5.0) days in the primary closure group,with no statistically significant difference between groups (t =1.701,1.309,P＞0.05).(2) Postoperative complications:26 and 19 patients in the biological mesh group and primary closure group had respectively perineal wound complications (1 patient combined with multiple complications),showing a statistically significant difference between groups (x2 =10.660,P＜0.05).The perineal wound infection,perineal hernia and disruption of perineal wound were respectively detected in 20,6,1 patients in the biological mesh group and 12,7,3 patients in the primary closure group,showing statistically significant differences between groups (x2 =3.931,5.282,P＜0.05).(3) Follow-up and survival situations:174 patients in the biological mesh group were followed up for 64 months (range,13-112 months),and 54 patients in the primary closure group were followed up for 51 months (range,23-76 months).The local recurrence rate,distal metastasis rate and overall survival rate were respectively 5.17％ (9/174),20.11％ (35/174),77.59％ (135/174) in the biological mesh group and 7.41％(4/54),24.07％(13/54),79.63％(43/54) in the primary closure group,with no statistically significant difference between groups (x2 =0.080,0.389,0.101,P＞0.05).Conclusions The biological mesh in the pelvic floor reconstruction of ELAPE for advanced low RC is safe and feasible.Compared with primary closure,biological mesh closure will extend perineal operation time and time of indwelling perineal drainage-tube,and increase hospital expenses,but doesn't affect total operation time and duration of postoperative hospital stay,meanwhile,it can also reduce the overall perineal wound complications,especially in perineal wound infection,perineal hernia and disruption of perineal wound.
ABSTRACT
Objective To analyze the different clinical effects of colpohysterectomy combined with anterior and posterior wall colporrhaphy with or without biological mesh for uterine prolapse.Methods From January 2010 to May 2015, colpohysterectomy combined with anterior and posterior wall colporrhaphy was performed in 106 cases of uterine prolapse, including 75 cases receiving biological mesh repair (experimental group) and 31 cases of non-biological mesh (control group).Clinical and surgical information of all patients was collected, and satistial analysis was done between the two groups.Results All the operations were accomplished successfully.There were no statistical differences in bleeding amount during operation [(34.5±7.3) ml vs.(32.1±4.9) ml, t=1.973, P=0.051], time to first flatus [(29.2±4.8) d vs.(30.2±5.3) d, t=-0.907, P=0.366], postoperative hospital stay [(6.1±1.5) d vs.(6.0±1.4) d, t=0.328, P=0.744], as well as the operative time [(91.4±3.4) min vs.(95.1±10.2) min, t=-1.970, P=0.051].At one year after surgery, in the experimental group there were 74 patients cured, 1 patient improved, and no invalid or recurrence case, while in the control group there were 27 patients cured, 1 patient improved, 3 cases of recurrence and no invalid case.The treatment effect of the experimental group was significant better than that of the control group (Z=-2.571, P=0.010).Conclusions Colpohysterectomy with anterior and posterior wall colporrhaphy with biological mesh can be selected for uterine prolapse patients without contraindications.The results of surgery are better with biological mesh, with low recurrence rate.
ABSTRACT
PURPOSE: This review reports the incidence of mesh-related erosion after ventral mesh rectopexy to determine whether any difference exists in the erosion rate between synthetic and biological mesh. METHODS: A systematic search of the MEDLINE and the Ovid databases was conducted to identify suitable articles published between 2004 and 2015. The search strategy capture terms were laparoscopic ventral mesh rectopexy, laparoscopic anterior rectopexy, robotic ventral rectopexy, and robotic anterior rectopexy. RESULTS: Eight studies (3,956 patients) were included in this review. Of those patients, 3,517 patients underwent laparoscopic ventral rectopexy (LVR) using synthetic mesh and 439 using biological mesh. Sixty-six erosions were observed with synthetic mesh (26 rectal, 32 vaginal, 8 recto-vaginal fistulae) and one (perineal erosion) with biological mesh. The synthetic and the biological mesh-related erosion rates were 1.87% and 0.22%, respectively. The time between rectopexy and diagnosis of mesh erosion ranged from 1.7 to 124 months. No mesh-related mortalities were reported. CONCLUSION: The incidence of mesh-related erosion after LVR is low and is more common after the placement of synthetic mesh. The use of biological mesh for LVR seems to be a safer option; however, large, multicenter, randomized, control trials with long follow-ups are required if a definitive answer is to be obtained.

Resection of the bowel is necessary for the repair of a ventral hernia after recovery from trauma in some cases. In such instances, polyester or polypropylene meshcannot be used due to the possibility of infection; we had to use biological mesh instead. We report a case in which a traumatic hernia was repaired with Permacol (Covidien, Norwalk, CT, USA). A 42-year-old male patient had been injured by a factory machine seven months prior to admission. At that time, he had abdominal wall injury and small bowel perforation. His abdominal wall had been a defect after operation. A CT scan of the abdomen showed that the left abdominal wall, which is lateral to left rectus abdominis muscle had only one muscle layer, an external oblique muscle, and that a previous abdominal incision had a defect along the entire incision. During the exploration, 10 cm of small bowel was removed due to firm adhesion to the previous surgical scar. Permacol mesh was applied and fixed with transfascial fixations and tacks by using the intraperitoneal onlay mesh technique. There were no complications after the surgery and the patient was discharged without any problems.
