Introducción: El sarcoma fibromixoide de bajo grado es una tumoración maligna con alto riesgo de desarrollar recurrencia y metástasis, siendo la resección quirúrgica con márgenes amplios el tratamiento principal, la preservación de la extremidad y su reconstrucción es de alta demanda para los cirujanos. Reporte de caso: Presentamos el caso de una mujer de 67 años con recurrencia de tumoración en rodilla desde hace 12 meses, operado dos años antes. Se realizo resección oncológica de tumoración con reconstrucción de articulación de rodilla con prótesis Endo Model y reconstrucción de aparato extensor con injerto sintético de malla de polipropileno más autoinjerto de semitendinoso y gracilis. La patela se reconstruyó con autoinjerto de cóndilo femoral posterior. A los 16 meses de seguimiento la paciente se encuentra libre de enfermedad, con puntaje de 27 en la escala para miembro inferior de la MSTS (Musculoskeletal Tumour Society). Conclusión: La combinación de injerto sintético con autoinjerto de isquiotibiales puede disminuir la tasa de falla de la reconstrucción del aparato extensor por resecciones oncológicas.

Introduction: Low-grade fibromyxoid sarcoma is a malignant tumor with a high risk of developing recurrence and metastasis, surgical resection with wide margins is the main treatment, limb preservation and reconstruction is in high demand for surgeons. Case of report: We present the case of a 67-year-old woman with a recurrence of a knee tumor that had been operated on two year earlier. Oncological resection of the tumor was performed with reconstruction of the knee joint with an Endo Model prosthesis and extensor mechanism reconstruction with a synthetic polypropylene mesh graft plus a semitendinosus and gracilis autograft. The patella was reconstructed with posterior femoral condyle autograft. At 16 months of patient follow-up, she is free of disease, with a score of 27 on the lower limb scale of the MSTS (Musculoskeletal Tumor Society). Conclusion: The combination of synthetic graft with hamstring autograft can reduce the failure rate of extensor mechanism reconstruction due to oncological resections.

An innovative technique of chest wall stabilization and reconstruction in traumatic flail chest: The figure-of-eight suture with polypropylene mesh and musculofascial flap / 中华创伤杂志(英文版)

Surgical stabilization of the flail chest is challenging and has no established guidelines. Chest wall integrity and stability are the main factors that ensure the protection of intrathoracic organs and an adequate respiratory function. Here, we report a novel chest wall reconstruction technique in a 45-year-old man with a traumatic left flail chest and open pneumothorax diagnosed both clinically and radiographically. Rib approximation and chest wall reconstruction was done using intercostal figure-of-eight suture and polypropylene mesh with vascularized musculofascial flap. The patient improved gradually and was discharged after three weeks of total hospital stay. He returned to regular working after a month with no evidence of respiratory distress or paradoxical chest movement. Follow-up visit at one year revealed no lung hernia or paradoxical chest movement. This is a novel, feasible and cost-effective modification of chest wall reconstruction that can be adopted for thoracic wall repair in case of open flail chest, which needs emergency surgical interventions even in resource constraint settings.

Changes of abdominal wall mechanics and pain after tension-free inguinal hernia repair with polypropylene mesh / 中国组织工程研究

BACKGROUND: Chronic pain after tension-free inguinal hernia repair is a common postoperative complication. An important cause of chronic pain is nerve injury. OBJECTIVE: To observe the effect of iliohypogastric nerve preposition on chronic pain after inguinal hernia repair and analyze its mechanics. METHODS: Totally 76 male inguinal hernia patients, from August 2013 to November 2016, aged 36-95 years in Second People’s Hospital of Lianyungang were selected. The patients were all treated with large-size polypropylene non-absorbable mesh insertion. The iliohypogastric nerve was placed in front of the mesh. Pain was followed up at 3, 6, and 12 months after operation. This study was approved by the Ethics Committee of Second People’s Hospital of Lianyungang. RESULTS AND CONCLUSION: (1) No chronic pain or recurrence was found in the 76 patients at 3, 6 and 12 months after surgery. (2) The pressure included vertical pressure and tangent pressure formed from intra-abdominal pressure on abdominal wall, directly affecting abdominal wall and artificial repair materials. This was the basic cause of the relative mechanical relationship between nerve and mesh. (3) The results showed that the tension-free inguinal hernia repair with the iliohypogastric nerve preposition could reduce the incidence of postoperative chronic pain, which may be related to the effect of postoperative abdominal pressure on tissue repair, especially the repair around the mesh.

Self-gripping mesh versus polypropylene mesh in ventral hernia repair: an observational study

Background: To compare clinical outcomes following sutureless Parietex ProGrip™ mesh in ventral hernia repair to traditional lightweight polypropylene mesh secured with sutures.Methods: This was a study conducted at the Department of General Surgery in Velammal medical college from August 2019 to February 2020. This prospective observational study involved, 60 patients, 30 each undergoing ventral hernia repair with polypropylene mesh with suture fixation and Parietex ProGrip™ precut mesh (P group) without fixation. The primary outcome measure was postoperative pain using the visual analog scale were assessed prior to surgery and up to 3 months postoperatively (VAS, 0-150 mm); other outcomes (duration of surgery, wound infection and recurrence of hernia) were assessed up to 3 months postoperatively.Results: Compared to baseline (preoperative), pain score below four on the visual analogue scale was higher in the test group at discharge (76.7%) and 24 hours (96.7%), while the pain was more in the study group at discharge (43.3%) and seven days (70%). The difference between groups was significant at both time points. In the test group, patients without fixation suffered less pain compared to those with single-suture fixation (48 hours: 100% versus 86.6%, p=0.038; 3 months: 100% versus 100%, p≤0.001). Surgery duration was significantly shorter in the test group (<60 minutes) (66.7% versus 40%; p<0.038). No recurrence was observed at three months in both groups.Conclusions: A self-gripping mesh for ventral hernia repair may result in less pain in the early postoperative phase. Recurrence rates reduce as well as the patient’s quality of life improves.

Efficacy comparison of immediate breast reconstruction after breast cancer surgery and modified radical mastectomy / 肿瘤研究与临床

Objective To investigate the clinical efficacy and cosmetic outcome of two methods of immediate breast reconstruction and modified radical mastectomy for the patients with breast cancer after breast cancer surgery. Methods The clinical data of 95 patients with early breast cancer in the First Affiliated Hospital of Jinzhou Medical University from October 2014 to September 2018 were retrospectively analyzed. The patients were divided into latissimus dorsi combined with implants group (27 cases), titanium-coated polypropylene mesh combined with implants group (18 cases) and modified radical group (50 cases). The differences of surgical data, postoperative complications and quality of life were compared in the three groups. The postoperative cosmetic effect of two immediate reconstruction groups was observed. Results The differences of drainage duration and intraoperative blood loss in the three groups were not statistically significant (both P > 0.05). There were statistical differences in the hospital stay and the postoperative quality of life score (both P < 0.01). The incidence of postoperative complications in latissimus dorsi combined with implants group, the titanium-coated polypropylene mesh combined with implants group and the modified radical group was 48.1％ (13/27), 22.2％ (4/18) and 12.0％ (6/50), respectively. And the difference between latissimus dorsi combined with implants group and the modified radical surgery group was statistically significant (χ 2 = 12.33, P < 0.01). The good rate of cosmetic effect in titanium-coated polypropylene mesh group was higher than that in latissimus dorsi combined with implants group, and there was no statistically significant difference [83.3％ (15/18) vs. 81.5％ (22/27), χ 2 = 0.025, P > 0.05]. Conclusions Immediate breast reconstruction including latissimus dorsi combined with implants or titanium-coated polypropylene mesh combined with implants after radical mastectomy on the basis of indications can improve the quality of life and the cosmetic results of patients, but postoperative treatment is necessary for the increased complications after the two reconstruction methods.

Methods Rabbit ADSC suspension were prepared.ADSCs were seeded onto polypropylene mesh scaffolds after passage and amplification and cultured invitro for 1 week .The polypropylene mesh and ADSC fixed polypropylene mesh were implanted respec-tively into the surface of rectus abdominis in rabbits.4 weeks later, adhesion and erosion of the meshes were evaluated, HE staining was used in histological observation and RT-PCR was applied to detect the dynamic changes of VEGF mRNA level.ADSCs were isola-ted from rabbit subcutaneous adipose tissue after collagenase digesting, filtrating and centrifuging. Results The results of flow cy-tometry showed that the expressions of CD44, CD73, CD90, CD45, CD14 and CD34 were 98.54%, 95.32%, 98.49%, 1.21%, 3.01%, 2.14%, respectively.Polypropylene mesh, ADSC-fixed polypropylene mesh had different degrees of corrosion and adhesion , but polypropylene mesh showed denser adhesion.In comparison with polypropylene,ADSC fixed polypropylene meshes induced a mil -der chronic inflammation response,with lower scores for inflammation (1.1 ±0.2 vs 0.6 ±0.1, P=0.001), higher scores for neovas-cularization (17.0 ±0.0 vs 2.6 ±0.3, P=0.000) and fibroblastic proliferation(0.9 ±0.1 vs 2.2 ±0.2, P=0.001).Relative a-mounts of VEGF mRNA of were significantly lower for ADSC-fixed polypropylene compared with the remaining polypropylene meshes (t=94.6, P<0.05). Conclusi on Polypropylene mesh scaffold with ADSCs exhibits excellent cellular compatibility and have a bright future in clinical practice.

Simultaneous Bilateral Anterior Inguinal Herniorrhaphy with Polypropylene Mesh Application and Open Prostatectomy.

Aims: Lower urinary tract symptoms (LUTS) are common in aging men. Benign prostatic hyperplasia (BPH) develops with advancing age. The incidence of inguinal hernia also increases with age. A significant number of elderly men with symptoms of BPH have inguinal hernia at the same time. Simultaneous preperitoneal inguinal hernia repair with other pelvic surgeries has been described, but it was not popular among urologists and general surgeons mainly because of high recurrence rate. Study Design: Prospective study. Place and Duration of Study: Department of Urology, Tabriz University of Medical Sciences, Imam Reza Hospital, between March 2010 and September 2013 Methodology: We evaluated the outcomes and complications of 37 patients who underwent open transvesical prostatectomy and simultaneous bilateral preperitoneal herniorrhaphy with application of polypropylene mesh Results: Twelve patients with bilateral direct hernia, 24 patients with bilateral indirect hernia and one patient with right side direct and left side indirect inguinal hernia were enrolled in our study. Four patients (10.8%) had bilateral recurrent hernias and 2 others (5.4%) had recurrent hernia on one side and primary hernia on the other side. Mean operation time was 86 minutes (71-110). The mean blood loss during surgery was 578 (240-1250)ml. The median clinical follow-up time was 13.7 months. During follow-up period surgical site infection, hematoma, chronic pain and recurrence were not detected. One (2.7%) lymphocele formation was detected. In all patients, the surgical outcomes were satisfactory. Conclusion: Simultaneous prostatectomy and preperitoneal herniorrhaphy with mesh application, is a convenient and safe procedure which can be performed easily by urologists.

Objective To compare the clinical efficacies of polypropylene-polyglactic composite mesh, polyester mesh, polypropylene mesh in Lichtenstein repair for inguinal hernia.Methods The clinical data of 1 080 patients with primary unilateral inguinal hernia who were admitted to the Tianjin People's Hospital from February 2012 to May 2013 were prospectively analyzed.A randomized controlled study was performed based on a random numble table.All the patients were allocated into the ProGrip group (Parietex ProGripTM Self-Fixating Mesh), PET group (ParietexTM Lightweight Monofilament Polyester Mesh) and PP group (BardTM Soft Mesh).Patients received standard Lichtenstein tension-free repair under local anesthesia and were followed up by outpatient examination and telephone interview till May 2014.The indexs observed during the follow-up included occurrence of complications, post-operative pain and postoperative health-related quality of life.The following indexes were recorded : time of mesh fixation, operation time, hernia recurrence, pain degree at postoperative week 1 and month 1, 6, 12 by numerical rating scale (NRS), quality of life at postoperative month 1 by SF-36 questionnaire survey including physical function, role physical, body pain, general health, vitality, social function, role emotional,mental health.Measurement data with normal distribution were presented as x ± s.Comparisons among groups were analyzed by ANOVA and pairwise comparison by t test.Measurement data with skewed distribution were presented as M (range) and repeated measurement data were analyzed using the repeated measures ANOVA.Count data were evaluated by the chi-square test and Fisher exact probability.Postoperative moderate and severe pain rates were evaluated by the Kaplan-Meier method and analyzed by the Log-rank test.Results There were 1 022 patients screened for eligibility including 367 patients in the ProGrip group, 346 patients in the PET group and 309 patients in the PP group.The time of mesh fixation and operation time were (1.3 ± 0.5) minutes and (30 ± 5) minutes in the ProGrip group, (4.9 ± 0.9) minutes and (45 ± 7) minutes in the PET group, (5.0 ± 0.9) minutes and (44 ± 7)minutes in the PP group, respectively, showing significant differences among the 3 groups (F =6.21, 4.33,P ＜ 0.05).There were significant differences in the time of mesh fixation and operation time between the ProGrip group and the PET group (t =1.36, 4.39, P ＜ 0.05), and also between the ProGrip group and the PP group (t =2.67, 2.99, P ＜ 0.05).There was no significant difference in the time of mesh fixation and operation time between the PET group and the PP group (t =0.98, 0.63, P ＞ 0.05).Nine hundred and nine patients were followed up for a median time of 13 months (range, 12-26 months) , with a follow-up rate of 88.943％ (909/1 022).The number of recurred hernia in the ProGrip group, the PET group and the PP group was 1, 0, 0,showing no significant difference (P ＞ 0.05).The NRS scores of pain from postoperative week 1 to postoperative month 12 were ranged from 0 (0-2) to 0 (0-0) in the ProGrip group, from 2(0-5) to 0(0-0) in the PET group and from 1 (0-4) to 0 (0-0) in the PP group.The number of patients with moderate and severe pain was ranged from 52(14.17％) to 0(0) in the ProGrip group, from 87 (25.14％) to 0 (0) in the PET group and from 89 (28.80％) to 0(0) in the PP group.There were no significant differences in the changing trends of NRS scores of pain and number of patients with moderate and severe pain among the 3 groups (F =1.66, x2=1.52, P ＞ 0.05).The scores of physical function in the ProGrip group, PET group, PP group at postoperative month 1 were 52 ± 4,50 ± 6, 50 ± 6, the scores of role physical were 50 ± 6, 50 ± 6, 50 ± 5, the scores of body pain were 52 ± 7, 52 ± 7, 52 ± 7, the scores of general health were 63 ± 4, 57 ± 9, 58 ± 8, the scores of vitality were 63 ± 5, 62 ± 6,63 ± 6, the scores of social function were 58 ± 4, 58 ± 8, 57 ± 8, the scores of role emotional were 59 ± 4, 57 ± 8,58 ± 8, and the scores of mental health were 65 ± 4, 63 ± 5, 63 ± 6, respectively, showing no significant differences in above indexes among the 3 groups (F =2.36,3.65,1.98,2.41, 6.32, 2.33, 4.21, 3.52, P ＞ 0.05).Conclusion Patients undergoing Lichtenstein repair for inguinal hernia with polypropylene-polyglactic composite mesh, polyester mesh and polypropylene mesh have comparative of incidence of postoperative complications, postoperative pain, quality of life, and present postoperative long-term low recurrence, low incidence of pain and relatively high quality of life.

Técnica de rives-stoppa en las eventraciones de la línea media: prescindencia de la fijación perimetral de la malla / Rives-Stoppa repair without mesh fixation for midline incisional hernias: long term follow up

Objetivo: La Técnica de Rives-Stoppa para las eventraciones de la línea media instala una malla retro rectal fijada en sus bordes con puntos percutáneos. Se han propuesto otras formas de fijación y en este estudio prescindimos de ella. Material y Método: El presente estudio observacional, descriptivo, prospectivo, se realizó en pacientes intervenidos consecutivamente entre los años 1995 y 2002. Se usó anestesia epidural con sedación profunda. Se usó la técnica estándar de Rives-Stoppa prescindiendo de la fijación perimetral. Los pacientes deambularon y se dieron de alta precozmente. Resultados: Se da cuenta de la evolución postoperatoria de 64 pacientes, 48 mujeres y 16 varones con una edad promedio de 58,9 (26-85) años. El 25 por ciento era hipertenso, el 9,3 por ciento diabético y el 80,2 por ciento obeso con un IMC > 30. La hospitalización promedio fue de 3,9 (2-16) días. Hubo 4 infecciones superficiales, un trombo embolismo pulmonar, un íleo abdominal prolongado y dos infecciones pulmonares. El seguimiento a largo plazo pudo realizarse en 48 pacientes (75 por ciento) comprobándose 5 recidivas (10,4 por ciento), ubicadas en el borde dista o proximal de la reparación herniaria, y 13,2 por ciento de dolor crónico moderado. A pesar de la recurrencia, el 97 por ciento de los pacientes se manifestó satisfecho o muy satisfecho con el tratamiento. Discusión: Los resultados son comparables con los dados a conocer con fijación de la malla. La modificación técnica propuesta disminuye el tiempo quirúrgico y el riego de infección y de neuralgia post operatoria. Para una ulterior disminución de las recidivas debe aumentarse el solapamiento cefálico y caudal de la malla.

Background: The Rives-Stoppa technique for midline incisional hernias places a Mersilene mesh in the retro rectal space, which is kept in place with transcutaneous sutures. Other forms of fixation have been proposed. Aim: To assess the long term results of the surgical technique without fixation of the mesh. Material and Methods: An observational, descriptive, prospective study performed in 64 patients aged 26 to 85 years (48 women) consecutively operated between 1995 and 2002. The standard Rives-Stoppa technique was used, except for the usage of a Prolene mesh without fixation. Ambulation was started on the first postoperative day and patients were discharged after removal of drains. Results: Eighty percent of patients were obese, 25% had high blood pressure and 9% were diabetic. Patients were discharged at a median of four (range two-16) days after surgery. Four superficial infections, one case of thromboembolic disease, one case of prolonged ileus and two pulmonary infections were recorded as complications. A long term follow-up was carried out in 48 patients (75%). Five patients had small recurrences (10%), localized at the cephalic or caudal borders of the mesh, and six patients (13%) reported slight abdominal pain. In spite of recurrences, 97% of patients were satisfied or very satisfied with the treatment. Conclusions: These results are similar to those obtained using mesh fixation. Increasing distal and proximal mesh overlap should enhance these results.

Tratamiento quirúrgico ambulatorio de pacientes con hernia inguinal / Outpatient surgical treatment in patients with inguinal hernia

Se efectuó un estudio descriptivo y prospectivo de 556 pacientes con hernia inguinal, expuestos a tratamiento quirúrgico ambulatorio en el Hospital Provincial Docente Clinicoquirúrgico "Saturnino Lora" de Santiago de Cuba, desde enero de 2010 hasta diciembre de 2012, con vistas a identificar los resultados, mediante técnicas de reparación herniaria (faciales y aponeuróticas) y el uso de bioprótesis. En la serie predominaron los hombres de 60 años y más con hernia inguinal indirecta, así como la anestesia local infiltrativa. Las técnicas quirúrgicas más empleadas resultaron ser las fasciales, realizadas sin tensión, en forma de herniorrafia o hernioplastia, con mallas de polipropileno y muy pocas recidivas.

A descriptive and prospective study was carried out in 556 patients with inguinal hernia, who underwent outpatient surgical treatment in "Saturnino Lora" Provincial Teaching Hospital of Santiago de Cuba, from January 2010 to December 2012, in order to identify the results by means of hernial repair techniques (facial and aponeurotic) and the use of bioprosthesis. Men of 60 years and over with indirect inguinal hernia and infiltrating local anesthesia predominated in the case material. The most used surgical techniques were the fascial ones, without tension, as herniorrhaphy or hernioplasty, with polypropylene mesh and few relapses.
