Objective To investigate the recent effect of full arthroscopic dual-beam reconstruction of the posterior cruciate ligament(PCL)using tibial Inlay technique.Methods From March 2007 to September 2009,17 PCL injured patients underwent full arthroscopic dual-beam PCL reconstruction using Inlay technique,including 16 males and 1 female,with an average age of 25 years(range,19-54).Of all cases,Lysholm score was(53.4±2.1)points,International Knee Documentation Committee(IKDC)rated C in 7,D in 10,and posterior drawer test(+)in 17.We used self-designed tibia tunnel drill system to produce the deep-limited bone tunnel.Follow-up began at 12 months after operation.Evaluate Lysholm knee score,IKDC rating,and posterior drawer test to compare the knee stability with that of preoperative.Observe the location of the bone block and healing by checking knee X-ray and spiral CT scan.Results Seventeen patients were followed up between 12 to 28 months,with an average of 17.8 months.In the last follow-up study,Lysholm score(93.5±1.7)points compared with that of preoperative was statistically significant different(P=0.016).IKDC rating of A grade in 15 cases,B in 2,compared with that of preoperative was statistically significant different(P=0.021).Posterior drawer test were negative in 15 cases,slight positive in 2.The X-ray and spiral CT scan showed the location of the bone block were perfect and healed well.Conclusion We can accurately produce the deep-limited bone tunnel by the tibia tunnel drill system with minor trauma,and the recent clinical effects of PCL reconstruction were pretty good.

Objective:To compare the effectiveness and recurrence rate of different types of mesh or without mesh in laparoscopic hiatal hernia repair.Methods:From Jan 2016 to Mar 2022 at the three hospital 90 patients with hiatal hernia, including 26 cases without mesh, 29 cases using synthetic mesh, and 35 cases using biological mesh underwent laparoscopic hiatal hernia repair.Results:The surgical procedures was successful in all the 90 cases without conversion to open surgeny. There were no statistically significant differences in operative time, intraoperative blood loss and postoperative hospital stay among the three groups ( P>0.05), and there were statistically significant differences in hospital cost between the group without mesh and synthetic mesh and biological mesh ( P<0.05). Long-term follow-up was achieved in 87 patients, with a follow-up rate of 96.7% (87/90), and a median follow-up time of 44 months. There were no significant differences in the incidence of postoperative complications (diarrhea, dysphagia, abdominal distension, chest pain), recurrence rate of symptoms (acid reflux, heartburn) and patient satisfaction among the three groups ( P>0.05). Conclusion:In laparoscopic hiatal hernia repair, the mesh should be carefully selected according to the specific intraoperative situation for a satisfactory clinical efficacy.

Inguinal incarcerated hernia in adults is a common acute abdomen in hernia and abdominal wall surgery. If not treated in time, it is easy to progress to constrictive hernia, lead to intestinal ischemic necrosis, cellulitis of tegmental tissue outside the hernia, hernia sac empyema, intestinal fistula, and even cause toxic shock, with significantly increased mortality. The types of incarceration are different and the corresponding management methods are different. Based on the proposal of the concept of musculopubic foramen hernia repair, inguinal incarcerated hernia includes incarcerated indirect hernia, incarcerated direct hernia, incarcerated femoral hernia, etc. At present, there is no uniform standard for the comprehensive treatment of different types of inguinal incarcerated hernia, and the clinical management strategies of adult inguinal incarcerated hernia still face serious challenges.

Hiatal hernia (HH) is a prevalent medical condition characterized by the protrusion of abdominal contents into the thoracic cavity through an enlarged diaphragmatic esophageal hiatus. The most common clinical manifestations of HH include acid reflux, heartburn, belching, coughing, and chest pain. Currently, there is a lack of standardized comprehensive treatment protocols for different types of HH, presenting significant challenges in their clinical management. In light of this, individualized treatment approaches should be followed by surgical practitioners when dealing with HH, in order to formulate the most appropriate clinical treatment plan tailored to each patient′s specific circumstances.

Objective:To investigate the relationship between parathyroid hormone（PTH） level and permanent hypoparathyroidism（PHPP） on the first day after radical papillary thyroidectomy, and its predictive value. Methods:A total of 80 patients with papillary thyroid cancer who underwent total thyroid resection and central lymph node dissection were collected and analyzed from January 2021 to January 2022. According to whether PHPP occurred after surgery, the patients were divided into hypoparathyroidism group and normal parathyroid function group, and univariate and binary logistics regression were used to analyze the correlation between PTH and serum calcium levels and PHPP on the first day after surgery in two groups. The dynamic changes of PTH at different time points after operation were analyzed. The area under the receiver operating characteristic was used to evaluate the predictive power of PTH on the development of PHPP after surgery. Results:Among the 80 patients with papillary thyroid cancer, 10 cases developed PHPP, with an incidence rate of 12.5%. Binary logistics regression analysis showed that PTH on the first postoperative day（OR=14.534, 95%CI: 2.377-88.858, P=0.004） was an independent predictive risk factor for postoperative PHPP. Taking PTH=8.75 ng/L on the first postoperative day as the cut-off value, the AUC of the area under the curve was 0.874（95%CI: 0.790-0.958, P<0.001）, the sensitivity was 71.4%, the specificity was 100%, and the Yoden index was 0.714. Conclusion:PTH level on the first day after total thyroid papillary carcinoma surgery is closely related to PHPP, and is an independent predictor of PHPP.
