ObjectiveTo analyze the reasons for Non-iatrogenic Complaint in general hospital inpatients and its preventive measures. MethodsWe analyzed 338 cases of non-iatrogenic complaint from January 2008 to December 2013 in two tertiary hospitals. ResultsComplaint for poor service attitude of medical personnel and poor communication between doctors/nurses and patients accounted for 86.1% and 62.4% respectively. Complaint for poor hospital management accounted for 46.2%. Non-iatrogenic complaint which appeared in the form of medical dispute complaint due to technical factors accounted for 20.1%. The first five departments being complained were Emergency Department, Pediatrics Department, Obstetrics Department, Osteology Department, Cardiology Department, respectively. Among all complaint, the proportion of complaint from emergency patients exceeded that from nonemergency patients. The proportion of complaint from patients whose duration of hospitalization exceeded two weeks were much more than that from patients whose duration of hospitalization was less than two weeks. The proportion of complaint from patients whoes frequency of hospitalization within one year was more than two times exceeded that from patients whose frequency of hospitalization within one year was less than two times. The proportion of complaint from patients who earned their high school diploma exceeded that from patients who droped out of their high school. The proportion of complaint from town patients exceeded that from rural patients. The proportion of complaint from patients under 45 years old was more than that from patients ≥ 45. ConclusionMore weight and strengthen should be placed on doctor-patient communication in clinical practice. Humane medical service deserve special emphasis and the patientcentered service idea should also be established, so that non-iatrogenic complaint may be reduced.
Objective To summarize the classification, diagnosis, and treatment of iatrogenic bile duct injury. Method The clinical data of 27 cases of iatrogenic bile duct injuries who treated in Central Hospital of Huzhou City from 2008–2013 were retrospectively analyzed. Results The classification of 27 cases: 5 cases of type Ⅰ, 18 cases of type Ⅱ, 2 cases of type Ⅲ, 2 cases of type Ⅳ. Diagnosis: 11 cases were immediately discovered at the time of the initial operation, include 1 case of type Ⅰ, 8 cases of type Ⅱ, 1 case of type Ⅲ, 1 case of type Ⅳ; 10 cases were detected in early stage after the initial operation, include 2 cases of type Ⅰ, 7 cases of type Ⅱ, 1 case of type Ⅲ; 6 cases were detected in delayed stage after the initial operation, include 2 cases of type Ⅰ, 3 cases of type Ⅱ, 1 case of type Ⅳ. Treatment effect: 17 cases for excellent, 5 cases for good, 4 cases for bad, the well recover rate was 84.6% (22/26). One case died after operation. A total of 26 cases were followed up, 1 case was lost to follow up. During the follow-up period, bile leakage occurred in 3 cases, infection of incision occurred in 2 cases, cholangitis occurred in 3 cases, and bile duct stricture occurred in 2 cases. Conclusions The best time of repairing for the iatrogenic bile duct injuries is at the time of the initial operation or early stage. According to the type of injury and the time of the injury was diagnosed, timely and effective treatment by intervention and (or) surgery is the key.
ObjectiveTo explore the value of modified method for intratumoral injection of thrombin in the treatment of iatrogenic pseudoaneurysms.MethodsClinical data of 28 patients with iatrogenic pseudoaneurysms after interventional treatment in our hospital from October 2012 to June 2018 were retrospectively analyzed. Twenty-one cases were treated with ultrasound-guided thrombin injection for pseudoaneurysms (Ultrasound group), and seven cases were treated with DSA-mediated balloon occlusion and thrombin injection for pseudoaneurysms (DSA group). The patients were followed-up at 1 day, 1 month and 3 monthS after operation.ResultsThe total success rates of the two groups were 100%. There was no treatment-related complications in the two groups. There was no recurrence after 1–3 months of treatment.ConclusionsIntratumoral injection of thrombin can be used for the treatment of iatrogenic pseudoaneurysm. The effect of the improved treatment is more significant. These two methods can be used as the best way to treat iatrogenic pseudoaneurysm with different neck diameters.
ObjectiveTo summarize the prevention and treatment of iatrogenic medial collateral ligament (MCL) injuries in total knee arthroplasty (TKA).MethodsThe relevant literature about iatrogenic MCL injuries in TKA was summarized, and the symptoms, causes, preventions, and treatments were analyzed.ResultsPreventions on the iatrogenic MCL injuries in TKA is significantly promoted. With the occurrence of MCL injuries, the femoral avulsion can be fixed with the screw and washer or the suture anchors; the tibial avulsion can be treated with the suture anchors fixation, bone staples fixation, or conservative treatment; the mid-substance laceration can be repaired directly; the autologous quadriceps tendon, semitendinosus tendon, or artificial ligament can be used for the patients with poor tissue conditions or obvious residual gap between the ligament ends; the use of implant with greater constraint can be the last alternative method.ConclusionNo consensus has been reached to the management of iatrogenic MCL injuries in TKA. Different solutions and strategies can be integrated and adopted flexibly by surgeons according to the specific situation.
ObjectiveTo explore the ultrasonic morphological indexes influencing the effectiveness of ultrasound-guided thrombin injection (UGTI) in the treatment of iatrogenic femoral artey pseudoaneury (IFAP).MethodsThe patients with IFAP treated by UGTI in the West China Hospital of Sichuan University from 2015 to 2017 were collected according to the inclusion criteria. The demographic data, comorbidities, clinical symptoms, ultrasonic morphological parameters, thrombin dosage, and postoperative complications were analyzed. The risk factors of technical success of UGTI were analyzed by logistic regression analysis. The technical success was defined as absence of flow within the FAP immediately after UGTI. ResultsA total of 53 patients who met the criteria of inclusion were included in this study. The technical and treatment success rates of UGTI were 84.9% (45/53) and 96.2% (51/53), respectively. No deep venous thrombosis, arterial thromboembolism, infection, bleeding, allergy, and other complications or death occurred in all patients. There were no statistical differences in the age, clinical symptoms, comorbidities (except hypertension, P=0.040), ultrasonic morphological parameters (except femoral artery diameter, P<0.001), and thrombin dosage between the patients with technical success and failure (P>0.05). Multivariate logistic regression analysis showed that the smaller femoral artery diameter was the risk factor of the technical failure [OR=0.350, 95%CI (0.165, 0.743), P=0.006]. Further adjustment of thebaseline data of patients (excluding patients with hypertension), the logistic regression analysis still found that smaller femoral artery diameter was the risk factor of the technical failure [OR=0.419, 95%CI (0.205, 0.860), P=0.018].ConclusionsUGTI in treatment of IFAP is minimally invasive and has a higher technical success rate. Smaller femoral artery diameter might affect technical success rate of UGTI.
Objective To investigate whether the outlet of the femoral tunnel will cause iatrogenic injury to the medial collateral ligament (MCL) during posterior cruciate ligament reconstruction (PCLR) and estimate the safe angle of femoral tunnel placement. MethodsThirteen formaldehyde-soaked human knee joint specimens were used, 8 from men and 5 from women; the donors’ age ranged from 49 to 71 years, with an average of 61 years. First, the medial part of the femur was carefully dissected to clearly expose the region of the MCL course and attachment on the femoral medial aspect and to outline the anterior margin of the region with a marked line. The marked line divided the medial femoral condyle into an area with an MCL course and a bare bone area which is regarded relatively safe for no MCL course. Then, the posterior cruciate ligament (PCL) was cut to identify the femoral attachment of the PCL. After the knee joint was fixed at a 120° flexion angle, the process of femoral tunnel preparation for the PCL single-bundle reconstruction was simulated. The inside-out technique was used to drill the femoral tunnel from the PCL femoral footprint inside the knee joint with an orientation to exit the medial condyle of the femur, and the combination angle of the two planes, the axial plane and the coronal plane, was adapted to the process of drilling femoral tunnels at different orientations. The following 15 angle combinations were used in the study: 0°/30°, 0°/45°, 0°/60°, 15°/30°, 15°/45°, 15°/60°, 30°/30°, 30°/45°, 30°/60°, 45°/30°, 45°/45°, 45°/60°, 60°/30°, 60°/45°, 60°/60° (axial/coronal). The positional relationship between the femoral tunnel outlet on the femoral medial condyle and the marked line was used to verify whether the tunnel drilling angle was a risk factor for MCL injury or not, and whether the shortest distance between the femoral exit center and the marked line was affected by the various angle combinations. Furthermore, the safe orientation of the femoral tunnel placement would estimated. ResultsWhen creating the femoral tunnel for PCLR, there was a risk of damage to the MCL caused by the tunnel outlet, and the incidence was from 0 to 100%; when the drilling angle of the axial plane was 0° and 15°, the incidence of MCL damage was from 69.23% to 100%. There was a significant difference in the incidence of MCL damage among femoral tunnels of 15 angle combinations (χ2=148.195, P<0.001). By comparison between groups, it was found that when drilling femoral tunnels at 5 combinations of 45°/45°, 45°/60°, 60°/30°, 60°/45°, and 60°/60° (axial/coronal), the shortest distances between the tunnel exit and the marked line were significantly different than 0°/45°, 0°/60°, 15°/45°, 15°/60°, and 30°/30° (axial/coronal) (P<0.05). Additionally, after comparing the median of the shortest distance with other groups, the outlets generated by these 5 angles were farther from the marked line and the posterior MCL. ConclusionThe creation of the femoral tunnel in PCLR can cause iatrogenic MCL injury, and the risk is affected by the tunnel angle. To reduce the risk of iatrogenic injury, angle combinations of 45°/45°, 45°/60°, 60°/30°, 60°/45°, and 60°/60° (axial/coronal) are recommended for preparing the femoral tunnel in PCLR.
Objective To explore the effectiveness of thumb blocking technique through closed reduction of ulnar Kirschner wire threading in the treatment of Gartland type Ⅲ supracondylar humerus fractures in children. MethodsThe clinical data of 58 children with Gartland type Ⅲ supracondylar humerus fractures treated with closed reduction of ulnar Kirschner wire threading by thumb blocking technique between January 2020 and May 2021 were retrospectively analyzed. There were 31 males and 27 females with an average age of 6.4 years ranging from 2 to 14 years. The causes of injury were falling in 47 cases and sports injury in 11 cases. The time from injury to operation ranged from 24.4 to 70.6 hours, with an average of 49.6 hours. The twitch of ring and little fingers was observed during operation, the injury of ulnar nerve was observed after operation, and the healing time of fracture was recorded. At last follow-up, the effectiveness was evaluated by Flynn elbow score, and the complications were observed. Results There was no twitch of the ring and little fingers when the Kirschner wire was inserted on the ulnar side during operation, and the ulnar nerve was not injured. All children were followed up 6-24 months, with an average of 12.9 months. One child had postoperative infection in the operation area, local skin redness and swelling, and purulent secretion exudation at the eye of the Kirschner wire, which was improved after intravenous infusion and regular dressing change in the outpatient department, and the Kirschner wire was removed after the initial healing of the fracture; 2 children had irritation at the end of the Kirchner wire, and recovered after oral antibiotics and dressing change in the outpatient department. There was no serious complication such as nonunion and malunion, and the fracture healing time ranged from 4 to 6 weeks, with an average of 4.2 weeks. At last follow-up, the effectiveness was evaluated by Flynn elbow score, which was excellent in 52 cases, good in 4 cases, and fair in 2 cases, and the excellent and good rate was 96.6%. ConclusionThe treatment of Gartland type Ⅲ supracondylar humerus fractures in children by closed reduction and ulnar Kirschner wire fixation assisted with thumb blocking technique is safe and stable, and will not cause iatrogenic ulnar nerve injury.
Objective To summarize the etiology mechanism and treatment of iatrogenic blepharoptosis after double eyelid surgery in Asia. Methods To extensively review the literature related to iatrogenic blepharoptosis after double eyelid surgery, and to summarize and analyze the related anatomical mechanism, existing treatment options, and indications. ResultsIatrogenic blepharoptosis is a relatively common complication after double eyelid surgery, sometimes it is combined with other eyelid deformities such as sunken upper eyelid and wide double eyelid, which makes it difficult to repair. The etiology is mainly caused by improper adhesion of tissues and scars, improper removal of upper eyelid tissue, and injury of a link of levator muscle power system. Whether blepharoptosis occurs after double eyelid surgery by incision or suture, it should be repaired by incision. The principles of repair include surgical loosening of tissue adhesion, anatomical reduction, and repair of damaged tissues. The key is to use surrounding tissues or transplanted fat to prevent adhesion. ConclusionWhen repairing iatrogenic blepharoptosis clinically, appropriate surgical methods should be selected based on the causes and severity of the blepharoptosis, combined with treatment principles, in order to achieve better repair results.
ObjectiveTo retrospectively analyze the surgical treatment of Stanford type A aortic dissection after coronary artery stenting, and to explore the surgical techniques and surgical indications. MethodsClinical data of 1 246 consecutive patients who underwent operations on Stanford type A aortic dissection from April 2016 to July 2019 in Beijing Anzhen Hospital were retrospectively analyzed. Patients with Stanford type A aortic dissection after coronary artery stenting were enrolled. ResultsFinally 19 patients were collected, including 16 males and 3 females with an average age of 54±7 years ranging from 35 to 66 years. There were 11 patients in acute phase, 15 patients with AC (DeBakey Ⅰ) type and 4 patients with AS (DeBakey Ⅱ) type. In AC type, there were 10 patients receiving Sun's surgery and 5 patients partial arch replacement. Meanwhile, coronary artery bypass grafting was performed in 7 patients and mitral valve replacement in 1 patient. Stents were removed from the right coronary artery in 4 patients. In this group, 1 patient died of multiple organ failure in hospital after operation combined with malperfusion of viscera. Eighteen patients recovered after treatment and were discharged from hospital. The patients were followed up for 30 (18-56) months. One patient underwent aortic pseudoaneurysm resection, one thoracic endovascular aortic repair, one emergency percutaneous coronary intervention due to left main artery stent occlusion, and one underwent femoral artery bypass due to iliac artery occlusion. ConclusionIatrogenic aortic dissection has a high probability of coronary artery bypass grafting at the same time in patients with Stanford type A aortic dissection after coronary artery stenting. Complicated type A aortic dissection after percutaneous coronary intervention should be treated with surgery aggressively.
