Objective To evaluate the surgical treatments of refractory sclerosing peritonitis related peritoneal dialysis.Methods Clinical data of 15 patients with refractory sclerosing peritonitis related to peritoneal dialysis treated in the General Surgery Department of the 900th Hospital of the Joint Logistics Support Force of the People's Liberation Army from June 30,2014 to May 30,2018.Among them,5 cases underwent"open abdomen peritoneal catheter removal+intestinal adhesiolysis+abdominal infection flushing and drainage with catheter",4 cases underwent"laparoscopic peritoneal catheter removal+intestinal adhesiolysis+abdominal infection flushing and drainage with catheter",3 cases underwent"laparoscopic peritoneal dialysis catheter removal+abdominal infection flushing and drainage with catheter",2 cases underwent"open abdomen peritoneal dialysis catheter removal+abdominal infection flushing and drainage with catheter",and 1 case underwent"laparoscopic examination combined with laparotomy exploration and removal of lower abdominal catheter+intestinal adhesiolysis+abdominal infection flushing and drainage with catheter".Age,gender,clinical symptoms,abdominal CT examination,peripheral blood routine,blood biochemistry,blood C-reactive protein(CRP),white blood cells,biochemistry,and aetiology of peritoneal dialysis fluid were collected and followed up,and the therapeutic effect was evaluated.Results 15 patients were transferred to the Department of Surgery after ineffective treatment in the Department of Internal Medicine.Preoperatively(after 5 days of antibiotic treatment)compared to before antibiotic treatment,there were no significant changes in blood WBC,blood NEUT％,CRP,and peritoneal fluid WBC(P＞0.05).Laparoscopic exploration or laparotomy exploration was performed,during which the peritoneal dialysis catheter was removed and the abdominal infection focus was cleared.A pelvic cavity washout drainage tube was left in place postoperatively.Fourteen patients had a good recovery after surgery,with effective control of peritonitis symptoms and no complications such as intestinal obstruction or enterocutaneous fistula.After the removal of the peritoneal dialysis catheter,all patients switched to hemodialysis.A comparison of inflammatory markers before and after surgery showed a significant decrease after surgery.Three days postoperatively compared to before surgery(after 5 days of antibiotic treatment),there were no significant changes in blood WBC,blood NEUT％,CRP,and peritoneal fluid WBC(P＞0.05).Seven days postoperatively compared to before surgery(after 5 days of antibiotic treatment),there was a significant decrease in blood WBC[(7.43±2.65)× 109/L VS(10.17±5.24)× 109/L],blood NEUT％[(88.23±9.02)％VS(85.07±11.57)％],and CRP[(152.88±113.01)mg/L VS(114.49±92.97)mg/L](P＜0.05);the peritoneal fluid WBC at 7 days postoperatively showed no significant change compared to before surgery(after 5 days of antibiotic treatment)(P＞0.05).The cases were followed up for at least 22 months,and 13 patients did not experience peritonitis or intestinal obstruction again.One patient died 39 days after surgery due to multiple organ failure,and one patient died from other causes after a 2-year follow-up.Conclusion For refractory sclerosing peritonitis related peritoneal dialysis that is ineffective in medical conservative treatment,On the basis of reasonable and effective antibiotics to control infection,surgical intervention should be actively carried out and surgical methods such as surgery should be used to control the progress of peritonitis,reduce mortality and improve the cure rate.

Objective:To explore one-stage total knee arthroplasty (TKA) combined with open reduction and internal fixation (ORIF) for knee osteoarthritis complicated with tibial stress fracture.Methods:The 3 patients were retrospectively analyzed who had been treated for knee osteoarthritis complicated with tibial stress fracture at Department of Orthopedics, Ganzhou District People＇s Hospital from March 2018 to March 2020. They were all female, aged from 54 to 76 years (average, 66 years). There were 2 transverse fractures and one short oblique fracture; all of them had knee varus deformity. The Hospital for Special Surgery (HSS) scores averaged 37.6 (from 28 to 50) for the left knee and 28.3 (from 22 to 39) for the right knee. One-stage TKA was performed for the articular surface while ORIF for the right tibial stress fracture for all patients. Recorded were fracture union time, HSS knee score and range of articular motion.Results:The 3 patients were followed up for 25 to 44 months (average, 32 months).The fracture union time ranged from 4 to 7 months (average, 5 months). The last follow-ups revealed no such complications as prosthesis loosening, peri-prosthesis osteolysis or joint instability. Knee varus deformity was corrected in all patients. The HSS knee scores at the last follow-up averaged 89.6 (from 88 to 91) for the left knee and 88.3 (from 85 to 90) for the right knee.Conclusion:In the treatment of knee osteoarthritis complicated with tibial stress fracture, one-stage TKA combined with ORIF can restore the function of knee joint, leading to fine curative effects.

Hepatocellular carcinoma (HCC) is one of the most common malignant tumors worldwide. At present, hepatectomy is one of the most frequent therapeutic options, whereas the high postoperative recurrence rate severely affects the long-term survival of HCC patients. Therefore, it is urgent to choose appropriate therapeutic regime to treat the recurrence of HCC to improve the long-term survival of HCC patients. Surgical treatment is an efficacious treatment for recurrent HCC, including re-hepatectomy, salvage liver transplantation and radiofrequency ablation. Currently, individualized treatment is recommended for postoperative recurrence of HCC. The selection of treatment should be conducted based on the tumor conditions after the first hepatectomy, the characteristics of recurrent tumors, baseline data of patients and recurrence time, etc., aiming to formulate appropriate treatment regimes for patients. In this article, these surgical regimes were reviewed and compared to explore appropriate surgical schemes for postoperative recurrence of HCC, aiming to provide reference for prolonging the survival of HCC patients.

Different centers collected and summarized their data in 2017 and sent back the questionnaires for summary. RESULTS: A total of 8 766 AA patients were enrolled from 43 medical centers, including 4 711 males (53.7%) with median age of 39 years and 958 (10.9%) patients over 65 years old. Of 8 776 patients, 5 677 cases (64.6%) received one or more imaging examinations, and the other 3 099 (35.4%) did not receive any imaging examination. A total of 1 858 (21.2%) cases received medical treatment, mainly a combination of nitroimidazoles (1 107 cases, 59.8%) doublet regimen, followed by a single-agent regimen of non-nitroimidazoles (451 cases, 24.4%), a nitroimidazole-free doublet regimen (134 cases, 7.2%), a triple regimen of combined nitroimidazoles (116 cases, 6.3%), nitroimidazole alone (39 cases, 2.1%) and nitroimidazole-free triple regimen (3 cases, 0.2%). Of the 6 908 patients (78.8%) who underwent surgery, 4 319 (62.5%) underwent laparoscopic appendectomy and 2589 (37.5%) underwent open surgery. Ratio of laparotomy was higher in those patients under 16 years old (392 cases) or over 65 years old (258 cases) [15.1%(392/2 589) and 10.0%(258/2 589), respectively, compared with 8.5%(367/4 316) and 8.0%(347/4 316) in the same age group for laparoscopic surgery, χ²=91.415, P<0.001; χ²=15.915,P<0.001]. Patients with complicated appendicitis had higher ratio of undergoing open surgery as compared to those undergoing laparoscopic surgery [26.7%(692/2 589) vs. 15.6%(672/4 316), χ²=125.726, P<0.001].The cure rates of laparoscopic and open surgery were 100.0% and 99.8%(2 585/2 589) respectively without significant difference (P=0.206). Postoperative complication rates were 4.5%(121/2 589) and 4.7%(196/4 316) respectively, and the difference was not statistically significant (χ²=0.065, P=0.799). The incidence of surgical site infection was lower (0.6% vs. 1.7%, χ²=17.315, P<0.001), and hospital stay was shorter [6(4-7) days vs. 6(5-8) days, U=4 384 348.0, P<0.001] in the laparoscopic surgery group, while hospitalization cost was higher (median 12 527 yuan vs. 9 342 yuan, U=2 586 809.0, P<0.001). CONCLUSIONS The diagnosis of acute appendicitis is still clinically based, supplemented by imaging examination. Appendectomy is still the most effective treatment at present. Laparoscopic appendectomy has become the main treatment strategy, but anti-infective drugs are also very effective.
