RESUMO
Objective:To investigate the characteristics and surgical management of mesh infection after tension-free repair of inguinal hernia.Methods:The clinical and follow-up data of 87 patients with mesh infection after tension-free repair of inguinal hernia at the Department of Hernia and Abdominal Wall Surgery,Beijing Chaoyang Hospital from 2018 to 2020 were retrospectively analyzed.Results:The most frequent type of repair was plug implantation, accounting for 57.5% of the procedures. The most common clinical presentation was a chronic sinus. 79.3% patients had a >3-month history of chronic infection. Staphylococcus aureus was the most common bacteria. All patients underwent open debridement. Fifty-one patients had a complete removal of the infected mesh, and 36 had partial removal. All patients were followed up for 18.7-54.2 months. There was no significant difference in the incidence of wound infection, seroma, hematoma, inguinal hernia recurrence, and chronic pain between those with complete removal and that partial removal (all P>0.05). Seventeen cases suffered recurrent sinus in the partial mesh removal group, and the incidence was significantly higher than that in the complete mesh removal group ( P<0.001). Conclusion:Infected mesh removal is an effective treatment for mesh infection after tension-free repair of inguinal hernia and should be removed as completely as possible.
RESUMO
Objective To evaluate preperitoneal tension-free herniorrhaphy for incarcerated and (or) strangulated inguinal hernia.Methods During Mar,2008 to Mar,2015,89 incarcerated and (or)strangulated hernia patients(incarcerated hernia group) and 1 741 primary inguinal hernia patients (elective group) underwent preperitoneal tension-free herniorrhaphy.Results The operation time (42 ± 8 min),length of stay (4.0 ± 2.6 d) and the time return to work (9.0 ± 3.3 d) in incarcerated hernia group were longer than in elective group of (38 ± 4 min),(3.0 ± 0.6 d) and (8.1 ± 2.5 d),respectively (all P ＜0.01).Blood loss [(10 ± 14 ml) vs (7 ±4 ml)] was compareble,P =0.148.There were 1 infection case and 20 seroma cases (22.5％) vs 5 infection cases and 187 seroma cases (12.7％) all P ＞0.05.Followup found hernia recurrence in one case in elective group.Conclusion Preperitoneal tension-free herniorrhaphy is safe and effective for the treatment of incarcerated and(or) strangulated hernia.
RESUMO
Objective To investigate the clinical effect of initiative content reduction surgery in the herniorraphy on the prevention and treatment of postoperative intra-abdominal hypertension of obese patients with giant ventral hernia.Methods The retrospective cross-sectional study was adopted.The clinical data of 62 obese patients with giant ventral hernias who were admitted to the Chao-Yang Hospital of Capital Medical University from January 2011 to December 2015 were collected.The initiative content reduction surgery was adopted during the herniorraphy of ventral hemia.Observation indices:(1) surgery situations:operation time,length of resected intestines,volume of intraoperative blood loss.(2) Postoperative recovery situations:change between preoperative and postoperative urethral bladder pressure,organ function of heart,lung,liver and kidney,time of gastrointestinal function recovery,time of drainage tube removal and duration of postoperative hospital stay.(3) Postoperative complications:incisional infection and intestinal fistula.(4) Follow-up situations.Follow-up using outpatient examination at 1 week,1 month,3 months and 6 months after surgery and using telephone interview at postoperative year 1 was conducted up to June 2016.The follow-up included hernia recurrence and chronic infection.Measurement data with normal distribution were represented as x ± s.Measurement data with skewed distribution were represented as M (range) and analyzed by rank-sum test.Results (1) Surgery situations:all the 62 patients received successful herniorraphy of giant ventral hemia combined with initiative content reduction surgery.Operation time,length of resected intestines and volume of intraoperative blood loss were (115 ±22)minutes,(207 ± 64)cm and (52 ± 35)mL.(2) Postoperative recovery situations:the preoperative urethral bladder pressure was 18 cmH2O (range,15-22 cmH2O,1 cmH2O =0.098 kPa) and postoperative urethral bladder pressure was 8 cmH2O (range,6-11 cmH2O),with a significantly statistical difference between before and after surgery (Z =-9.662,P ＜ 0.05).There was no abnormal function of heart,lung,liver and kidney after operation.The time of gastrointestinal function recovery,time of drainage tube removal and duration of postoperative hospital stay were 3.8 days (range,3.0-6.0) days,(3.8 ± 1.1) days and (14.5 ± 1.9) days.(3)Postoperative complications:of 62 patients,4 were complicated with incisional infection and improved after symptomatic treatment.There was no intestinal fistula.(4) Follow-up situations:all the 62 patients were followed up for (36 ± 19) months.During the follow-up,3 patients had incisional hernia recurrence and then were followed up without reoperation.No chronic infection occurred.Conclusion Initiative content reduction surgery is effective and feasible in the prevention and treatment of intraoperative intra-abdominal hypertension of obese patients with giant ventral hernia.
RESUMO
Objective Spontaneous pneumothorax occurred mainly because of bulla rupture and its formation process and pathogenesis were unknown,the study was to detect the express level of the cytokines KL-6,FGF-10 and MMP-9 in the spontaneous pneumothorax patients with bulla and researched its significance.Methods Selected 24 cases of bulla resection for spontaneous pneumothorax patients,the immunohistochemical staining techniques and enzyme-linked immunosorbent assay (ELISA) was taken to detect the expression level of KL-6,FGF-10 and MMP-9 of the bulla site and the bulla adjacent site.Results Immunohistochemical results showed that the staining intensity of the KL-6 and FGF-10 in groups of bulla site was higher than those in groups of bulla adjacent site while there was no significant difference of MMP-9 in the two groups.ELISA results showed that the expression levels of the KL-6 and FGF-10 in groups of bulla site are higher than those in groups of bulla adjacent site and the results had statistically significant (P ＜ 0.05),while there was no statistically significant of MMP-9 in the two groups(P ＞0.05).Conclusion The expression of the KL-6 and FGF-10 in the bulla site in primary spontaneous pneumothorax patients was higher than that in the normal site ; the pulmonary fibrosis mediated by KL-6 and the lung-bronchial congenital abnormalities mediated by abnormal expression of FGF-10 might have correlation with bulla formation.There was no statistically significant of the MMP-9 expression between the two groups and the correlation between inflammation mediated by MMP-9 and bulla formation was not clear.
