ObjectiveTo review research progress of surgical treatment of patellar fractures.MethodsThe domestic and foreign literature about patellar fracture treatment in recent years was extensively consulted, and the advantages, disadvantages, and indications of various surgical treatments were summarized.ResultsThe patella plays an important role in knee flexion and extension activities, and the fracture significantly affects the patient’s quality of life. At present, the surgical methods include open reduction and internal fixation and patella resection. The internal fixation methods include ring/binding patella fixation, tension band wiring and improved technology, tension band wiring combined with other methods, screw fixation (including absorbable screws), steel plate fixation, and patella fixator fixation. Each surgical method has different indications, advantages, and disadvantages. Choosing an appropriate treatment plan plays a crucial role in clinical prognosis.ConclusionThere are many surgical treatments for patellar fractures. In order to improve the effectiveness and reduce postoperative complications, it is necessary to choose the most appropriate treatment strategy for the type of fracture.
To analyze the causes of failure to reduce acute infantile intussusception with gas enema. 441 cases of acute infantile intussusception in our hospital who failed to be reduced with gas-enema, and underwent the operative therapy were analyzed. Result: 92 cases (20.9%) were intestinal necrosis, 184 cases (41.7%) double intussusception, 27 cases (6.1%) organic pathological changes and 8 cases (1.8%) intestinal perforation caused by gas-enema reduction. All the cases had a successful recovery after surgery. Conclusion: The main causes of failure to reduction with gas-enema were as follows: ①double intussusception, ②intestinal necrosis, ③late for visiting a doctor, ④organic pathological changes, ⑤perforation (in the process of gas-enema reduction). The importance of early diagnosis is emphasized.
Objective To assess the effectiveness of sternocleidomastoid muscle (SCM) flap in preventing gustatory sweating syndrome following parotidectomy. Methods Databases including The Cochrane Library, MEDLINE, EMbase, CBM, CNKI, VIP and WanFang Data were searched from inception to March 2012 to retrieve randomized controlled trials (RCTs) about SCM flap in preventing gustatory sweating syndrome following parotidectomy. The data of studies meeting the inclusion criteria were extracted by two reviewers independently, the methodological quality was assessed and cross-checked, and meta-analysis was performed using the RevMan 5.1 software. Results A total of 10 RCTs involving 825 patients were included. The results of meta-analyses showed that compared with the blank control group, SCM flap could obviously decrease the subjective incidence of gustatory sweating syndrome by 78% (OR=0.22, 95%CI 0.08 to 0.59, P=0.003) and the objective incidence by 83% (OR=0.17, 95%CI 0.05 to 0.60, P=0.006). The sensitivity analysis indicated the above results were robust. The evidence based on GRADE system was of “low quality”. There was no obvious publication bias according to the tunnel chart. Conclusions Current evidence shows that SCM flap can obviously decrease both subjective and objective incidence of gustatory sweating syndrome following parotidectomy. Considering the limitation of the included studies, this conclusion still needs to be tested by more large-scale and high-quality RCTs taking SCM function as one of the outcome.
To study the changes in diagnosis and treatment of pediatric choledochal cyst in the past 10 years, a retrospective analysis was made in 79 children with choledochal cyst, who were admitted into our hospital from 1982 to 1998. Results show that in the past years, the clinical manifestation of choledochal cyst in children have become less obvious for earlier consultation. B-mode ultrasounscanning should be the first choice since it aids in the diagnosis of choledochal cyst as well as its related and complicated diseases. Choledochectomy is the only radical treatment for choledochal cyst in children.
ObjectiveTo observe the status of thrombocytopenia in adult patients after cardiac surgery, and to explore its mechanism and clinical significance.MethodsRetrospective analysis of 240 patients after cardiac surgery in the 2nd ward of surgical intensive care unit (ICU) of Fuwai Hospital from May to June 2020 was conducted, including 137 males and 103 females with a mean age of 56.0±12.0 years. According to postoperative platelet status, the patients were divided into a thrombocytopenia group and a non-thrombocytopenia group. The clinical baseline data, preoperative platelet count, postoperative minimum platelet count, volume of drainage, transfusion of blood products, mechanical ventilator time, ICU stay, hospital stay and complications were compared between the two groups.ResultsThe mean preoperative platelet count was 199×109/L±55×109/L and the mean postoperative platelet nadir was 109×109/L±37×109/L, with a mean reduction rate of 44.1%±15.8%. The platelet count of 235 (97.9%) patients after operation was lower than that before operation. Among them, 98 (40.8%) patients had platelet count<100×109/L, 46 (19.2%)<75×109/L and 8 (3.3%)<50×109/L. Results of multivariable logistic analysis showed that cardiopulmonary bypass time>120 min (OR=2.576, 95%CI 1.313-5.053, P<0.05) was an independent risk factor for postoperative thrombocytopenia. Mechanical ventilator time (25.5±16.8 h vs. 17.3±8.5 h, P<0.05), ICU stay (85.2±54.7 h vs. 60.0±33.9 h, P<0.05) and hospital stay (15.8±6.2 d vs. 14.2±3.9 d, P<0.05) were longer in the thrombocytopenia group (<100×109/L) compared with the non-thrombocytopenia group (>100×109/L). More drainage volume [685 (510, 930) mL vs. 560 (440, 790) mL, P<0.05] and complications occurred in the thrombocytopenia group. In multivariable analysis, thrombocytopenia was significantly inversely associated with prolonged ICU stay (OR=2.993, 95%CI 1.622-5.524, P<0.05).ConclusionThrombocytopenia occurs commonly after adult cardiac surgery, and the incidence in different types of surgery varies. Postoperative thrombocytopenia is related to the prolonged recovery. Extracorporeal circulation may be a contributing factor to thrombocytopenia, and further studies investigating mechanism and strategies to reduce postoperative thrombocytopenia are needed.
