Objective To evaluate clinical results of concomitant mitral valve replacement （MVR） and modified maze procedure with Atricure bipolar radiofrequency for chronic atrial fibrillation （AF）. Methods Clinical data of 59 patients with mitral valve diseases and chronic AF who underwent concomitant MVR and bipolar radiofrequency ablation in Subei People’s Hospital from June 2010 to September 2012 were retrospectively analyzed. There were 22 male and 37 female patients with their age of 29-71 （48±11） years. The AF duration was 1.2-26.0 （7.2±3.4） years. Preoperatively，there were 20 patients with New York Heart Association （NYHA） class Ⅱ，31 patients with NYHA class Ⅲ and 8 patients with NYHA class Ⅳ. There were 32 patients with moderate to severe mitral stenosis，9 patients with moderate to severe mitral regurgitation and 18 patients with combined mitral stenosis and regurgitation. There were 42 patients with tricuspid regurgitation. The left artial dimension was 39-98 （55.2±8.9） mm. Left atrial thrombus was found in 9 patients. Atricure bipolar radiofrequency system was used for right atrial ablation under normothermic cardiopulmonary bypass （CPB） with beating heart first，then for ablations of the left and right pulmonary vein orifices and left atrium under moderate hypothermia with heart arrest. MVR was performed after ablation procedures were completed. Amiodarone was routinely used postoperatively and patients were periodically followed up after discharge. Results There was no in-hospital death. CPB time was 65-180 （99±28）minutes，aortic cross-clamping time was 46-123 （69±17）minutes，and ablation time was 15-28 （21±4）minutes. Postoperatively，heart rhythm immediately changed to sinus rhythm （SR） in 44 patients，remained AF in 10 patients and atrial flutter in 1 patient. Temporary pacemaker was used for 4 patients with bradycardia （3 patients recovered SR and 1 patient remained AF later）. Fifty-eight patients were followed up after discharge for 6-33 months，and 1 patient was lost during follow-up. Patients’ SR rate was 86.2 % （50/58），91.4% （53/58），89.7 % （52/58），84.6 % （33/39）and 71.4 % （5/7）at discharge，3 months，6 months，1 year and 2 years after discharge respectively. There was no thrombotic event during follow-up. Conclusion Concomitant MVR and modified maze procedure with Atricure bipolar radiofrequency is a safe procedure for chronic AF with good short-term results.
ObjectiveTo evaluate the feasibility and effectiveness of proximal femoral nail anti-rotation (PFNA) combined with curettage and bone graft through Watson-Jones approach in the treatment of proximal femur benign tumors and tumor like lesions.MethodsThe clinical data of 38 patients with benign tumors and tumor like lesions in the proximal femur who were treated through the Watson-Jones approach with PFNA combined with curettage and bone graft between January 2008 and January 2015 were retrospective analysed. There were 24 males and 14 females with an average age of 28 years (range, 15-57 years). Pathological types included 20 cases of fibrous dysplasia, 7 cases of bone cyst, 5 cases of aneurysmal bone cyst, 3 cases of giant cell tumor of bone, 2 cases of enchondroma, and 1 case of non-ossifying fibroma. Before operation, hip pain occurred in 19 patients, pathological fracture occurred in 12 patients, limb shortening and coxa varus deformity was found in 4 patients, and 3 patients received surgery for the local recurrence. The operation time, intraoperative blood loss, and full-weight bearing time after operation were recorded. Patients were followed up to observe union of bone graft and the position of internal fixator on X-ray films and CT images. Visual analogue scale (VAS) score was used to evaluate the level of pain. The Musculoskeletal Tumor Society (MSTS93) score was used to evaluate lower limb function. Harris hip score was used to evaluate hip joint function.ResultsThe operation time was 130-280 minutes (mean, 182 minutes) and the intraoperative blood loss was 300-1 500 mL (mean, 764 mL). After operation, 3 cases of fat liquefaction of incision healed successfully by carefully dressing, and the rest incisions healed by first intention. All patients started partially weight-bearing exercise at 2-4 weeks after operation. The total weight-bearing time was 3-6 months (mean, 4.2 months). All the patients were followed up 24-108 months (median, 60 months). Imaging examination showed that the bone graft fused and the fusion time was 8-18 months (mean, 11.4 months). During the follow-up period, there was no complication such as pathological fracture, femoral head ischemic necrosis, hip joint dislocation, internal fixation loosening and fracture, and no tumor recurrence or distant metastasis occurred. At last follow-up, the VAS score, MSTS93 score, and Harris score were significantly improved when compared with preoperative ones (P<0.05).ConclusionThe treatment of proximal femoral benign lesions by PFNA combined with curettage and bone graft through the Watson-Jones approach is safe and effective, with advantages of better mechanical stability, less residual tumor, and less postoperative complications.

The root of the flap was thoracodorsal artery and thoracodorsal vein, which was anastomosed with superficial temporal artery and vein, facial artery and vein, lingual artery and vein,and so on.During the operation, long thoracic nerve was dissected and anastomosed with facial nerve. The sizes of the flaps were 12 cm×8 cm16 cm×12 cm.Results All free-muscle flaps healed well after the transplant. The face and buccal area looked chubby and rounded. There were no obvious protuberance and discontentment on the buccal area. The shoulders of all patients moved well. The facial contourof the patients recovered well during the follow-up period (1.3 years). Conclusion The method has a good result, The long-term effect needs further study.
Objective To explore the practicability and safety of ultrasonic bone curette in the laminoplasty of spinal canal after resection of intraspinal tumors. Methods The clinical data of 17 patients with thoracolumbar intraspinal tumors treated with ultrasonic bone curette after resection of intraspinal tumors between December 2015 and April 2017 were retrospectively analyzed. All patients were male, aged 42-73 years with an average of 57.4 years. The disease duration was 2-47 months with an average of 21.1 months. Among them, there were 4 cases of thoracic intrathoracic tumors (T10 in 1, T12 in 3) and 13 cases of lumbar intrathoracic tumors (L1 in 5, L2 in 4, L3 in 2, and L4 in 2). Postoperative pathological diagnosis showed that 8 cases were schwannoma, 4 cases were meningioma, 2 cases were neurofibroma, 2 cases were dermoid cyst, and 1 case was ependymoma. Spinal nerve function was evaluated preoperatively according to Frankel classification criteria, with 2 cases of grade B, 7 cases of grade C, and 8 cases of grade D. During the operation, the time of single segmental vertebral canal posterior wall incision, the overall operation time, intraoperative blood loss, intraoperative dural injury, and cerebrospinal fluid leakage, spinal cord and nerve root injury were recorded. At 3-6 months after operation, the tumor and bone healing were observed according to MRI and CT three-dimensional reconstruction, and the spinal nerve function was evaluated by Frankel classification. Results The time of ultrasonic osteotomy for the posterior wall of a single segmental vertebral canal was 3.4-5.7 minutes, with an average of 4.1 minutes. The overall operation time was 135-182 minutes, with an average of 157.3 minutes. The intraoperative blood loss was 300-500 mL, with an average of 342.6 mL. There was no accidental dural injury, and cerebrospinal fluid leakage, nerve root injury, or spinal cord injury. The incision healed by first intention after operation. All the 17 patients were followed up 9-18 months, with an average of 12.7 months. MRI examination showed no tumor recurrence, and CT three-dimensional reconstruction showed good bone healing in all patients. During the follow-up, there was no loosening or rupture of the internal fixator and there was no re-compression of the spinal cord. At last follow-up, according to Frankel classification, there were 1 case as grade B, 5 cases as grade C, 7 cases as grade D, and 4 cases as grade E. Conclusion The application of ultrasonic bone curette in laminoplasty of spinal canal after resection of intraspinal tumors can preserve the integrity of the bone ligament structure of posterior column, maintain the volume of vertebral canal, and has high safety, practicability, and good postoperative effectiveness.
Objective To report our experience in living donor liver harvesting of right lobe grafts. MethodsThe data of 76 living donors of right lobe grafts hepatectomy between August 2007 and December 2008 were studied. Before operation, the graft size, remnant liver volume rate, fatty liver, middle hepatic vein type, and the level of portal hypertension of recipient were comprehensive assessed to determine whether harvested middle hepatic vein. The graft was harvested depending on the port vein and hepatic artery ischemia-line. B-ultrasound was used to definite the structure and branch of middle hepatic vein, and intraoperative cholangiography was performed to definite the structure and variation of bile duct. Donor operative time, intraoperative blood loss, postoperative hospital stay, levels of bilirubin, international normalized ratio （INR）, and ALT, and complications after operation were recorded. Results All the operations were successful. The operative time was (8.3±1.3) h, the blood loss was (325±127) ml without blood transfusion in operation. The ALT, INR, and bilirubin recovered on the 12th day. The most common complication in early post-operation was wound infection in 5 cases, 4 cases had cholestasis, 4 cases occurred cross-section bile leakage, and 11 cases occurred varying degrees of delayed gastric emptying in 4～7 d after operation, who were all alleviated by corresponding treatments. The hospital stay was 9～21 d (median: 14 d) after operation. Conclusion Preoperative evaluation of the hepatic anatomy and precise surgical procedure are crucial, which will help the development of graft harvesting and rehabilitation of donor.
Objective To investigate the effect of ultrasonic bone curette in anterior cervical spine surgery. MethodsA clinical data of 63 patients with cervical spondylosis who were admitted between September 2019 and June 2021 and met the selection criteria was retrospectively analyzed. Among them, 32 cases were operated with conventional instruments (group A) and 31 cases with ultrasonic bone curette (group B). There was no significant difference between the two groups (P>0.05) in gender, age, surgical procedure, surgical segment and number of occupied cervical space, disease type and duration, comorbidities, and preoperative Japanese Orthopaedic Association (JOA) score, cervical dysfunction index (NDI), and pain visual analogue scale (VAS) score. The operation time, intraoperative bleeding, postoperative drainage, postoperative hospital stay, and the occurrence of postoperative complications were recorded in both groups. Before operation and at 1, 3, and 6 months after operation, the JOA score and NDI were used to evaluate the function and the postoperative JOA improvement rate was calculated, and VAS score was used to evaluate the pain improvement. The anteroposterior and lateral cervical X-ray films were taken at 1, 3, and 6 months after operation to observe whether there was any significant loosening and displacement of internal fixators. ResultsCompared with group A, group B had shorter operation time and postoperative hospital stay, less intraoperative bleeding and postoperative drainage, and the differences were significant (P<0.05). All incisions healed by first intention in the two groups, and postoperative complications occurred in 5 cases (15.6%) in group A and 2 cases (6.5%) in group B, showing no significant difference (P>0.05). All patients were followed up 6-12 months (mean, 7.9 months). The JOA score and improvement rate gradually increased in groups A and B after operation, while the VAS score and NDI gradually decreased. There was no significant difference in VAS score between 3 months and 1 month in group B (P>0.05), and there were significant differences between the other time points of each indicator in the two groups (P<0.05). At 1, 3, and 6 months after operation, the JOA score and improvement rate in group B were better than those in group A (P<0.05). X-ray films examination showed that there was no screw loosening or titanium plate displacement in the two groups after operation, and the intervertebral cage or titanium mesh significantly sank. ConclusionCompared with traditional instruments, the use of ultrasonic bone curette assisted osteotomy in anterior cervical spine surgery has the advantages of shorter operation time, less intraoperative bleeding, less postoperative drainage, and shorter hospital stay.

Objective To explore the effectiveness of percutaneous pedicle screw fixation on the indirect reduction of posterosuperior fracture fragment in the thoraculumbar burst fractures. Methods Patients with thoracolumbar fractures treated in the Fourth People’s Hospital of Zigong from September 2017 to September 2019 were collected retrospectively. All patients were treated with percutaneous pedicle screw fixation. The main observation indexes before operation, 3 days after operation and 1 year after operation were compared, including the height ratio of the anterior margin of fractured vertebra, the inversion angle of posterosuperior fracture fragment, the fragment displacement, the occupancy rate of spinal canal, the Cobb angle of kyphosisat, Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI). Results A total of 38 patients were included. All patients were followed up for more than 1 year. During the follow-up period, there were no complications such as nerve injury, incision infection, internal fixation loosening or fracture. The operation time was (91.7±10.4) min, the amount of intraoperative bleeding was (94.3±19.5) mL, and the length of surgical incision was (9.3±1.8) cm. The height ratio of the anterior margin of fractured vertebra, the inversion angle of posterosuperior fracture fragment, the fragment displacement, the occupancy rate of spinal canal, the Cobb angle of kyphosisat 3 days after operation were significantly improved compared with those before operation (P<0.05); the height ratio of the anterior margin of fractured vertebra, the occupancy rate of spinal canal, and the Cobb angle of kyphosisat 1 year after operation were also significantly improved compared with those before operation (P<0.05); the height ratio of the anterior margin of fractured vertebra and the occupancy rate of spinal canalat 1 year after operation were significantly improved than those 3 days after operation (P<0.05), but the Cobb angle of kyphosis 1 year after operation was significantly lost than that 3 days after operation (P<0.05). The VAS score and ODI index 3 days and 1 year after operation were significantly improved compared with those before operation (P<0.05), and the VAS score and ODI index 1 year after operation were improved compared with those 3 days after operation (P<0.05). Conclusion The percutaneous pedicle screw fixation can effectively reduce the retropulsed bone fragment indirectly and restore the Cobb angle of kyphosis of the thoraculumbar burst fractures without neurological deficit, and at the same time reduce the operation time and surgical trauma.
ObjectiveTo discuss the effect of palliative drainage operation on the life quality of hilar cholangiocarcinoma. MethodsCholangiocarcinoma data of our hospital in recent 21 years were analysed retrospectively. They were divided into four groups: RouxenY choledochojejunostomy group, bridge internal drainage group, PTCD (or ERBD) internal drainage group, and operative external drainage group. The operative mortality, incidence of postoperative cholangitis and survival period were compared among groups.ResultsThe total perioperative mortality of 193 cases of palliative operation was 9.3%, there was no difference among groups (P＞0.05). The rate of postoperative cholangitis in the bridge internal drainage group (10.0%) was lower than that of RouxenY choledochojejunostomy group (19.4%),P＜0.05, the rate of cholangitis in PTCD (or ERBD) internal drainage group (37.5%) and operative external drainage group (38.1%) were significantly higher than that of RouxenY choledochojejunostomy group (P＜0.01). There was no significant difference between RouxenY choledochojejunostomy group 〔(9.2±1.8) months〕 and PTCD (or ERBD) internal drainage group 〔(8.8±1.9) months〕 in survival period (P＞0.05)，but the survival period of the above groups were significantly higher than that of bridge internal drainage group 〔(6.5±1.6) months〕，P＜0.05, and operative (or PTCD) external drainage group 〔(4.3±2.0) months〕,P＜0.01.ConclusionThe life quality of RouxenY choledochojejunostomy group is better than that of bridge internal drainage group and PTCD (or ERBD) internal drainage group, the life quality of external drainage is worse than that of the other groups.
