ObjectiveTo intend to propose a new clinical classification of congenital biliary dilatation (CBD) which is more concise and suitable for diagnosis and treatment, and explore feasibility and reliability of the new classification. MethodsBased on the preoperative imaging data of patients with CBD admitted to the Department of Pediatric Surgery of West China Hospital of Sichuan University, from January 2015 to December 2018, a new classification of CBD was accomplished according to the site of bile duct dilatation lesions, which was named HUAXI CBD classification. The CBD was classified into 4 types: type Ⅰ (distal extra-hepatic bile duct dilatation), type Ⅱ (distal extra-hepatic combined with right and left primary hepatic bile duct dilatation), type Ⅲ (extra-hepatic combined with secondary and above hepatic bile duct dilatation), and type Ⅳ (intra-hepatic bile duct dilatation). Meanwhile, the feasibility and reliability of the HUAXI CBD classification were analyzed. ResultsA total of 300 patients with CBD were included in this study. According to the HUAXI CBD classification method, 240 cases were type Ⅰ, 48 cases were type Ⅱ, 10 cases were type Ⅲ, and 2 cases were type Ⅳ. For type Ⅰ, 236 patients underwent cholecystectomy and Roux-en-Y hepaticojejunostomy and 4 cases were treated non-operatively; For type Ⅱ, 48 patients underwent cholecystectomy, central hepatic duct reconstruction and Roux-en-Y hepaticojejunostomy; For type Ⅲ, 9 patients underwent cholecystectomy and Roux-en-Y hepaticojejunostomy, 5 of which had intrahepatic dilatation confined to part of the liver lobe and underwent partial hepatectomy with intra-hepaticojejunostomy. One case was treated with percutaneous transhepatic cholangial drainage (PTCD) only; two type Ⅳ patients were treated with PTCD only. Patients with type Ⅰ had a normal hepatobiliary function after surgery and a good prognosis; patients with type Ⅱ had good recovery of liver function in 37 cases (77.1%), but 11 cases (22.9%) had postoperative complications during follow-up; patients with type Ⅲ and Ⅳ had high incidence of cholangitis (6/10, 2/2, respectively) and choledocholithiasis (5/10, 2/2, respectively) after surgery, especially those with diffuse intrahepatic dilatation having a poor prognosis, eventually developing cirrhosis and necessitating liver transplantation. ConclusionThe HUAXI CBD classification is consistent with treatment principles, concise and easy to remember, and more suitable for pediatric clinical application, which can effectively assist in the selection of clinical treatment strategies for children with BD.
Objective To investigate the feasibility of reconstruction of the contracted eye socket by an application of the expanded forehead island skin flap with the supratrochlear and supraorbital arteries. Methods From June 2002 to June 2005, 6 patients with the eye socket defects were treated with an expanded forehead island skin flap with the supratrochlear and supraorbital arteries.There were 4 males and 2 females, aged 16-42 years. The defects were caused bytumors in 2 patients, by trauma in 3, and by chemical burns in 1; the defects were in the left eyes of 4 patients and in the right eyes of the remaining 2 patients, with the illness course of 1 year to 4 years.All the patients first underwent the skin and soft tissue expanding operation on the donor forehead skin area; 1 month later, the transplant of the expanded forehead island skin flap with the supratrochlear and supraorbital arteries was performed to reconstruct the eye sockets. The flaps ranged in size from 8 cm×5 cm to 10 cm×6 cm.The appearance and functional recovery of the reconstructed eye sockets were observed after operation. Results The follow-up of all the patients for 1-3 years revealed that the skin flaps survived, with no visible contracture, and the fine sensory function was still present. The artificial eyes could be steadily placed in the reconstructed eye sockets. The donor areas were healed with no visible hyperplastic scars. Conclusion Reconstruction of the eye socket with an expanded forehead island skin flap with the supratrochlear and supraorbital arteries is a feasible, effective and simply method, and the patient can have a concealed incision, a satisfactory appearance, and a fine sensory function.
Objective To investigate the feasibility and effectiveness of selective treatment of senile osteoporotic thoracolumbar burst fractures of Denis type B with kyphoplasty and Jack vertebral dilator. Methods Between August 2007 and May 2011, 30 patients (32 vertebra) with osteoporotic thoracolumbar burst fractures of Denis type B were treated with kyphoplasty and Jack vertebral dilator. There were 7 males and 23 females, aged 57-85 years (mean, 76.9 years). The injured vertebrae included T11 in 2 vertebrae, T12 in 11 vertebrae, L1 in 7 vertebrae, L2 in 5 vertebrae, L3 in 3 vertebrae, and L4 in 4 vertebrae. The visual analogue scale (VAS) score, Oswestry disability index (ODI), the anterior and middle height of the vertebral body, and the Cobb angle were assessed before and after operation. Results The operation was completed smoothly in all cases; no cement leakage or intraoperative complication was found. Obvious back pain relief was achieved in all patients after operation. Thirty patients were followed up at 1 week and 6 months after operation. The VAS score was decreased from 8.2 ± 1.3 before operation to 1.5 ± 0.9 at 1 week after operation and 1.9 ± 0.5 at 6 months after operation; the ODI was decreased from 82.4% ± 15.0% to 17.8% ± 9.5% and 23.0% ± 8.6%; the anterior height of the vertebral body was increased from (19.5 ± 3.2) mm to (24.8 ± 3.0) mm and (24.0 ± 2.6) mm; the middle height of the vertebral body was increased from (18.5 ± 3.4) mm to (23.7 ± 3.7) mm and (22.8 ± 3.5) mm; the Cobb angle was decreased from (14.9± 7.5)° to (7.6 ± 6.0)° and (8.3 ± 6.0)°; and there were significant differences in the VAS score, ODI, the anterior and middle height of the vertebral body, and the Cobb angle between at pre- and at post-operation (P lt; 0.05), but no significant difference between at 1 week and at 6 months after operation (P gt; 0.05). Conclusion Kyphoplasty with Jack vertebral dilator for selective treatment of senile osteoporotic thoracolumbar burst fractures of Denis type B can restore the anterior and middle height of the vertebral body, correct the Cobb angle, and relieve pain, and it has good short-term effectiveness and safety.
Abstract: Objective To summarize the immediate effects and the near and midterm followup results of transthoracic balloon valvuloplasty for newborns and infants with severe and critical pulmonary valve stenosis to find out an effective plan for onestop balloon valvuloplasty. Methods From March 2006 to March 2010, 32 patients including 23 males and 9 females with severe and critical pulmonary valve stenosis were treated in Fu Wai Hospital. Their age ranged from 5 days to 11 months (4.59±3.21 months). Weight of the patients ranged from 2.3 to 10.5 kg (6.48±2.05 kg). Dilatation was performed under general anesthesia with intubation and the guidance of echocardiography. During the follow-up period, all survivors had serial echocardiographic assessment to measure the transpulmonary pressure gradient (TPG) and the degree of pulmonary regurgitation. Results All operations were successful with no severe postoperative complications. Hemodynamic indexes were stable after operation with TPG lowered from from 82±27 mm Hg preoperatively to 23±12 mm Hg postoperatively (t=15.28, Plt;0.05). Only 4 patients had a TPG of more than 40 mm Hg on echocardiography before leaving the hospital. Tricuspid regurgitation was decreased significantly with 17 cases of nonregurgitation, 13 cases of light regurgitation and 2 cases of moderate regurgitation. Saturation of peripheral oxygen in all the patients increased to higher than 95%. Followup time ranged from 1 month to 4 years (16±11 months). The results of the follow-up were satisfying for all the patients. The average TPG was 17±10 mm Hg with only one above 40 mm Hg. Pulmonary valve regurgitation was found in 24 patients including 23 with light pulmonary regurgitation and 1 with moderate regurgitation. Conclusion Transthoracic balloon valvuloplasty for newborns and infants with severe and critical pulmonary valve stenosis is safe and effective.
Objective To investigate the application of the fibrous envelope of tissue expanders for the tension reduction. Methods Between June 2005 and May 2011, 21 patients with facial scar were treated with skin soft tissue expansion. There were 6 males and 15 females, aged 19-33 years (mean, 24.5 years), including 19 cases of hypertrophic scar and 2 cases of atrophic scar with disease duration of 1-31 years. The scars ranged from 4 cm × 2 cm to 25 cm × 10 cm. The tissue expander was implanted under normal skin adjacent to lesions in the first stage. And the post-expanded skin flap was designed as advance flap or transpositional flap as supplement in the second stage. Fibrous envelope at the base was fixed to the periosteum or fascia nearby first, and then sutures were used between envelopes at the base and on the skin flap or to the dermis of the skin flap to keep the mouth and lower eyelid in proper position. It reduced the tension of incision and maintained the contour of the face and neck. Results After the first stage operation, 2 cases had replaced expanders because of infection and leakage. No complication of infection or hematoma occurred after the second stage operation. The patients were followed up 1-18 months (mean, 10.2 months); of them,12 were followed up more than 1 year. No secondary deformity (deviation of mouth angle, eyebrows pulling, or eyelid ectropion) occurred. The flaps had good appearance and color. The satisfactory results were achieved. Conclusion In skin soft tissue expansion of the face, the fibrous envelopes at the base could reduce the tension of the incision and prevent the deformity of the mouth and lower eyelids.
Transcatheter aortic valve replacement is an effective treatment for aortic stenosis currently, especially in elderly, surgical high-risk, and surgical procedures-intolerant patients with severe aortic stenosis. After several generations of updates in design and function, the self-expandable valves have shown significant efficacy in treating aortic stenosis patients with bicuspid aortic valve, bioprosthetic valve failure or small annulus, and superiority in terms of valve durability, and the favorable hemodynamic outcomes could translate into clinical endpoint benefit. This literature review summarizes the advantages and recent advances of the self-expandable valves in transcatheter aortic valve replacement.
