Objective To investigate feasibility and curative effect of ultrasound-guided percutaneous transhepatic cholangioscopy in treatment of complicated hepatolithiasis. Methods The data of 42 patients with complicated hepatolithiasis from June 2012 to June 2017 in the Hepatobiliary Surgery, the First Affiliated Hospital of Xi’an Jiaotong University were retrospectively analyzed. All the patients were treated with ultrasound-guided percutaneous transhepatic cholangioscopy, including the first stage of dilation and drainage and the second stage choledochoscopy. Results The operations of the 42 patients were successfully performed. No case was converted to the conventional laparotomy. The puncture sites of 10 cases were at the right intrahepatic bile duct, 25 cases were at the left intrahepatic bile duct, and 7 cases were at the bilateral intrahepatic bile duct. The residual stones were removed by two stage choledochoscopy in the 31 patients, 11 patients had the residual stones. After the first stage, there were 4 cases of the bile duct hemorrhage, 8 cases of the cholangitis, 1 case of the pleural effusion and 1 case of the infection, 2 cases of the postoperative drainage tube shedding. After the second stage, there were 3 cases of the cholangitis and 3 cases of the postoperative drainage tube shedding. The stones of the 10/31 patients with stone removal occurred and the diseases of 9/11 patients with stone residual were stable during the following-up of (18.6±7.8) months. Conclusion Ultrasound-guided percutaneous transhepatic cholangioscopy including the first stage of dilation and drainage plus the second stage choledochoscopy is safe and effective in treatment of complex intrahepatic bile duct stones, it is an effective supplement to traditional surgery.
Objective To investigate the accuracy and safety of percutaneous screw fixation for pelvic and acetabular fractures with remote navigation of orthopedic robot based on 5G technology. Methods Between January 2021 and December 2021, 15 patients with pelvic and/or acetabular fractures were treated with percutaneous screws fixation which were placed by remote navigation of orthopedic robot based on 5G technology. There were 8 males and 7 females. The age ranged from 20 to 98 years, with an average of 52.1 years. The causes of trauma included traffic accident injury in 6 cases, falling from height injury in 6 cases, fall injury in 2 cases, and heavy object smashing injury in 1 case. The time from injury to operation ranged from 3 to 32 days, with an average of 10.9 days. There were 8 cases of simple pelvic fractures, 2 simple acetabular fractures, and 5 both pelvic and acetabular fractures. There were 7 cases of pelvic fractures of Tile type B2, 2 type B3, 1 type C1, and 3 type C2; 4 cases of unilateral anterior column fracture of the acetabulum, 2 bilateral anterior column fractures, and 1 anterior wall fracture. CT images within 5 days after operation were collected for screw position assessment. The screw planning time and guidewire placement time were recorded, as well as the presence of intraoperative adverse events and complications within 5 days after operation. Results All patients achieved satisfactory surgical results. A total of 36 percutaneous screws were inserted (20 sacroiliac screws, 6 LC Ⅱ screws, 9 anterior column screws, and 1 acetabular apical screw). In terms of screw position evaluation, 32 screws (88.89%) were excellent and 4 screws (11.11%) were good; there was no screw penetrating cortical bone. The screw planning time ranged from 4 to 15 minutes, with an average of 8.7 minutes. The guidewire placement time ranged from 3 to 10 minutes, with an average of 6.8 minutes. The communication delayed in 2 cases, but the operation progress was not affected, and no serious intraoperative adverse events occurred. No delayed vascular or nerve injury, infection, or other complications occurred within 5 days after operation. No cases need surgical revision. ConclusionThe fixation of pelvic and acetabular fractures by percutaneous screw with remote navigation of orthopedic robot based on 5G technology is accurate, safe, and reliable.
ObjectiveTo evaluate the feasibility and short-term effectiveness of bilateral percutaneous balloon kyphoplasty through unilateral transverse process-extrapedicular approach for osteoporotic vertebral compression fracture (OVCF) of lumbar.MethodsA retrospective analysis was made on the clinical data of 93 patients with OVCF of lumbar who met the selection criteria between January 2018 and June 2019. According to the different surgical methods, they were divided into group A (44 cases, treated with bilateral percutaneous balloon kyphoplasty through unilateral transverse process-extrapedicular approach) and group B [49 cases, treated with percutaneous kyphoplasty (PKP) via bilateral transpedicle approach]. There was no significant difference in gender, age, body mass index, T value of bone mineral density, injury cause, fractured level, time from injury to operation, comorbidities, and preoperative Cobb angle of injured vertebra, visual analogue scale (VAS) score, and Oswestry disability index (ODI) between the two groups (P>0.05). The operation time, intraoperative fluoroscopy times, bone cement injection amount, and incidence of bone cement leakage were recorded and compared between the two groups; Cobb angle of the injured vertebrae, VAS score, and ODI were measured before operation, at 2 days and 1 year after operation. The contralateral distribution ratio of bone cement was calculated according to the anteroposterior X-ray film at 2 days after operation.ResultsThe operation time and the intraoperative fluoroscopy times in group A were significantly less than those in group B (P<0.05). There was no bone cement adverse reactions, cardiac and cerebrovascular adverse events, and no complications such as puncture needles erroneously inserted into the spinal canal and nerve injuries occurred in the two groups. Bone cement leakage occurred in 6 cases and 8 cases in groups A and B, respectively, all of which were asymptomatic paravertebral or intervertebral leakage, and no intraspinal leakage occurred; the bone cement injection amount and incidence of bone cement leakage between the two groups showed no significant differences (P>0.05). The contralateral distribution ratio of bone cement in group A was significantly lower than that in group B (t=2.685, P=0.009). Patients in both groups were followed up 12-20 months, with an average of 15.3 months. The Cobb angle of the injured vertebrae, VAS score, and ODI in the two groups were significantly improved at 2 days after operation, however, the Cobb angle of the injured vertebra at 1 year after operation was significantly lost when compared with the 2 days after operation, the VAS score and ODI at 1 year after operation were significantly further improved when compared with the 2 days after operation, the differences were all significant (P<0.05). There was no significant difference in the Cobb angle of the injured vertebrae, VAS score, and ODI between the two groups at each time point after operation (P>0.05).ConclusionBilateral percutaneous balloon kyphoplasty through unilateral transverse process-extrapedicular approach is comparable to bilateral PKP in short-term effectiveness with regard to fracture reduction, reduction maintenance, pain relief, and functional improvement. It has great advantages in reducing operation time and radiation exposure, although it is inferior in bone cement distribution.
The majority of incidentally found and screen-detected lung cancer is manifested as ground-glass nodule (GGN), which is more likely to be detected in the young people, women and non-smokers. An appropriate management strategy for GGN can not only reduce the mortality of lung cancer but also minimize overtreatment. Although most of persistent GGNs are finally diagnosed as adenocarcinoma or precursor glandular lesions, the GGN-featured lung cancer is characterized as indolent growth or even non-growth. Therefore, scheduled follow-up might be safe for the special radiologic type under a certain condition. We should design the individualized diagnosis and treatment strategy for each patient. The treatment decision-making depends on various factors, including invasion, dynamic change, efficacy and safety of the treatment, as well as physical and psychic condition of the patients. Different from other types of lung cancer, the indolent feature of GGN-featured lung cancer allows a long time to intervene. Therefore, the determination of proper timing for intervention should be made cautiously. Surgical resection is still the principal treatment for GGN-featured lung cancer. However, there is still no consensus on the optimal surgical approach for GGN-featured lung adenocarcinoma. Currently, sublobar resection without lymphadenectomy has been recommended to the patients with precursor glandular lesions. In light of the GGN-featured lung cancer which generally represents a local lesion, local ablation therapies have been used in those patients, especially in the ones who are inoperable or refuse to undergo surgery. The percutaneous local ablation includes different techniques: radiofrequency ablation, microwave ablation and argon-helium cryoablation. The local ablation is safe, minimally invasive and repeatable. In addition, it offers the advantage to biopsy and treatment synchronously. Percutaneous ablation has the potential to be an alternative of surgery to cure GGN-featured lung cancer based on emerging evidences. The efficacy of transbronchial ablation guided by ultrasound or electromagnetic navigational system in the treatment of GGN-featured lung cancer has been primarily validated. As a developing technology, it might be a promising approach but needs further exploration. With the advance in ablation technology, we do believe that the interventional therapy will play an equal role as surgery in curative treatment of GGN-featured lung cancer in the future. Personalized treatment considering the condition of patients and the features of the lesion will maximize the benefit of every patient. This article will explore the diagnosis and treatment strategies of GGN on the basis of further understanding of GGN, and introduce the application of ablation therapy in GGN from the perspective of respiratory intervention.
ObjectiveTo investigate the significance of catheter thrombolysis combined with one-stage iliac vein percutaneous transluminal angioplasty (or stent implantation) in the treatment of acute left lower extremity deep venous thrombosis secondary to Cockett syndrome.MethodsForty-one cases of Cockett syndrome complicated with acute left lower extremity deep vein thrombosis were retrospectively analyzed and summarized in our hospital from January 2016 to June 2019. Catheter directed thrombolysis was performed under the protection of filter, and percutaneous transluminal angioplasty or stent implantation was performed in the first stage of the iliac vein stenosis or occlusion after thrombolysis. Compared the circumference of upper and lower legs of 15 cm above and below patella of the healthy and affected limbs, before and after treatment, and analyzed the venous patency rate.ResultsThe average time of using thrombolytic catheter were (7±3) days, and the average dosage of urokinase was (358.32±69.38) ×104 U. A total of thirty-five Bard stents were implanted (35 cases), four cases underwent percutaneous transluminal angioplasty, and two cases gave up treatment. Before and after treatment, the circumference difference of the higher leg, the circumference difference of the lower leg, and the venous patency were significantly different before and after thrombolysis (P<0.01). The venous patency rate was 58%–75% in this group, and the average venous patency rate was (61±10)%. There was no severe bleeding complication occurred. Thirty-five patients were followed up for 3–26 months, the preservation rate of the valve was 82.86% (29/35), and the first patency rate of iliac vein was 100% (39/39). During the follow-up period, thrombosis recurred in one case of untreated iliac vein, and acute thrombosis in the right side of one case was caused by long iliac vein stent entering the inferior vena cava. No pulmonary embolism was found.ConclusionOn the basis of catheter thrombolysis, one stage removal of iliac vein obstruction in the treatment of acute left lower extremity deep venous thrombosis can relieve the clinical symptoms, reduce the recurrence rate of thrombosis, and reduce the occurrence of deep vein thrombosis syndrome after catheter thrombolysis.
ObjectiveTo summarize the treatment and experience of percutaneous transhepatic portal vein recanalization by endovascular approach for treatment of cavernous transformation of the portal vein (CTPV) in a child. MethodThe clinical data of a child with idiopathic CTPV who underwent percutaneous transhepatic portal vein recanalization by endovascular approach were retrospectively analyzed. ResultsWe described a novel percutaneous transhepatic portal vein recanalization approach that had successfully treated a child with idiopathic CTPV following a multidisciplinary team evaluation. The operation time was 1.5 h and blood loss was approximately 1 mL. The child recovered uneventfully at 9-month follow-up, without any clinical evidence of CTPV complications. ConclusionIn light of our successful management, we can envision that the portal vein recanalization is an important therapeutic supplement for treating CTPV and will result in a paradigm change.
Objective To explore the effectiveness of ultrasound-guided percutaneous Herbert screw for the treatment of fresh nondisplaced carpal scaphoid fracture. Methods Between May 2013 and August 2015, 15 patients with fresh nondisplaced carpal scaphoid fractures (Krimmer type A2) were treated with ultrasound-guided Herbert screw fixation. There were 12 males and 3 females with an average age of 33.4 years (range, 18-51 years). The causes of injury included 9 cases of falls, 3 cases of training injuries, and 3 cases of machine injuries. The interval from injury to surgery was 2-15 days (mean, 5 days). No other complication was found. The operation time, intraoperative blood loss, intraoperative fluoroscopy times, and the fracture healing time were recorded. The wrist function was assessed by the modified Mayo wrist score standard. Results The operation time was 28-53 minutes (mean, 33.9 minutes); the intraoperative blood loss was 5-30 mL (mean, 10.5 mL); the intraoperative fluoroscopy was 2-6 times (mean, 2.6 times). All 15 patients were followed up 6-18 months (mean, 10.5 months). One patient developed pain and soreness in the skin of the nail entrance, and gradually relieved after fumigation. No complication such as infection occurred. All fractures healed clinically, and the healing time was 8-16 weeks (mean, 11.6 weeks). At last follow-up, the modified Mayo wrist score was 76-99 (mean, 92.5). Among them, 12 cases were excellent, 2 cases were good, and 1 case was fair, and the excellent and good rate was 93.3%. Conclusion Ultrasound-guided fixation with Herbert screw is a reliable treatment method for fresh nondisplaced carpal scaphoid fractures with small invasion, less bleeding, and small radiation damage.
ObjectiveTo investigate treatment of severe acute pancreatitis (SAP) concurrent peripancreatic walled-off necrosis.MethodsThe clinical data and treatment of a patient with SAP from the Second Affiliated Hospital of Chongqing Medical University were retrospectively analyzed. The results of discussion of multidisciplinary team (MDT) were summarized.ResultsThe patient was admitted for the SAP with high fever, abdominal pain, and dyspnea for 2 weeks. The enhanced CT scan of the upper abdomen presented severe acute necrotizing pancreatitis with massive peripancreatic walled-off necrosis and pleural effusion. After the full discussion of SAP MDT, the percutaneous sinus tract necrosectomy (PSTN) was performed to relieved the symptom. After the two-stage PSTN treatment, the peripancreatic necrotic tissue was obviously reduced, the drainage was unobstructed, the clinical symptoms and biochemical indicators were obviously improved, and the patient was discharged on day 6 after the surgery.ConclusionsSAP is a critical situation with rapid progression and high mortality, and timing and approach of intervention for complications are very difficult to handle. PSTN could treat SAP with early appearance of infection or walled-off necrosis, which has advantages of less trauma, higher efficiency, and faster recovery as compared with traditional method and is of valuable in clinical practice.
ObjectiveTo explore the safety and efficacy of transesophageal echocardiography (TEE)-guided percutaneous intervention for patent ductus arteriosus (PDA) in obese teenagers.MethodsFrom January 2018 to June 2019, 21 obese teenagers with PDA treated with femoral artery occlusion guided by TEE in the Department of Cardiac Surgery, Dalian Children's Hospital of Dalian Medical University were included in this study, including 13 males and 8 females aged 12.8-17.3 (15.1±1.7) years, with an average weight of 51.0-89.0 (73.4±10.1) kg. The operative effect was evaluated. ResultsAll patients successfully received the surgery, and none was changed to radiation-guided or thoracotomy ligation. The average operating time was 23.9±6.8 min, the average postoperative hospitalization time was 3.8±0.6 d. No peripheral vascular injury, intracardiac infection or pericardial effusion occurred. The mean follow-up time was 19.5±4.9 months, and the results of all reexaminations were good.ConclusionFor some PDA children with obesity, emphysema or thoracic malformation, it is difficult to block PDA by transthoracic ultrasound-guided percutaneous intervention, and TEE can avoid the interference of chest wall and lung qi, or other factors. It is an effective supplementary guidance method worthy of promotion.
ObjectiveTo evaluate the effectiveness of orthopedic robot with modified tracer fixation (short for modified orthopedic robot) assisted percutaneous kyphoplasty (PKP) in treatment of single-segment osteoporotic vertebral compression fracture (OVCF). Methods The clinical data of 155 patients with single-segment OVCF who were admitted between December 2017 and January 2021 and met the selection criteria was retrospectively analyzed. According to the operation methods, the patients were divided into robot group (87 cases, PKP assisted by modified orthopedic robot) and C-arm group (68 cases, PKP assisted by C-arm X-ray fluoroscopy). There was no significant difference in gender, age, body mass index, T value of bone mineral density, therapeutic segment, grade of vertebral compression fracture, and preoperative visual analogue scale (VAS) score, midline vertebral height, and Cobb angle between the two groups (P>0.05). The effectiveness evaluation indexes of the two groups were collected and compared. The clinical evaluation indexes included the establishment time of working channel, dose of intraoperative fluoroscopy, the amount of injected cement, VAS score before and after operation, and the occurrence of complications. The imaging evaluation indexes included the degree of puncture deviation, the degree of bone cement diffusion, the leakage of bone cement, the midline vertebral height and the Cobb angle before and after operation. Results The establishment time of working channel in robot group was significantly shorter than that in C-arm group, and the dose of intraoperative fluoroscopy was significantly larger than that in C-arm group (P<0.001). There was no significant difference in the amount of injected cement between the two groups (t=1.149, P=0.252). The patients in two groups were followed up 10-14 months (mean, 12 months). Except that the intraoperative VAS score of the robot group was significantly better than that of the C-arm group (P<0.05), there was no significant difference between the two groups at other time points (P>0.05). No severe complication such as infection, spinal cord or nerve injury, and pulmonary embolism occurred in the two groups. Five cases (5.7%) in robot group and 7 cases (10.2%) in C-arm group had adjacent segment fracture, and the difference in incidence of adjacent segment fracture between the two groups was not significant (χ2=1.105, P=0.293). Compared with C-arm group, the deviation of puncture and the diffusion of bone cement at 1 day after operation, the midline vertebral height and Cobb angle at 1 month after operation and last follow-up were significantly better in robot group (P<0.05). Eight cases (9.1%) in the robot group and 16 cases (23.5%) in the C-arm group had cement leakage, and the incidence of cement leakage in the robot group was significantly lower than that in the C-arm group (χ2=5.993, P=0.014). There was no intraspinal leakage in the two groups. ConclusionCompared with traditional PKP assisted by C-arm X-ray fluoroscopy, modified orthopedic robot-assisted PKP in the treatment of single-segment OVCF can significantly reduce intraoperative pain, shorten the establishment time of working channel, and improve the satisfaction of patients with operation. It has great advantages in reducing the deviation of puncture and improving the diffusion of bone cement.
