Objective To evaluate transsphincteric operation (Mason operation) for rectal tumors.Methods Retrospective study was used to analyze the experience of Mason operation for 150 patients with mid and lower rectal tumors between Aug 1990 to Dee 2008. Results There were villous adenoma in 75 cases,early rectal cancer in 48 and advanced rectal cancer in 9,submucosal carcinoid nodule in 23.Of the 126 rectal tumor patients,120 underwent partial rectectomy,6 underwent segmental rectectomy.Seventeen out of the 21 rectovaginal fistula or rectourethral fistula cases underwent successful one-stage repair.Six patients(4%)developed wound infection.Five patients(3.3%)were complicated with recto-cutaneous fistula.Two patients(4.3%) suffered from local recurrence in 46 followed up early staged rectal carcinoma with a five-year survival rate of 84.5%(39/46).On discharge from hospital no patient suffered from incontinence.Conclusion Mason operation is satisfactory with good exposure and simple access to the rectum,which Was suitable for those lesions that could be locally resected on mid and lower rectum.

Objective To compare the effect of single-tube drainage with that of two-tube drainange in non-small cell lung cancer(NSCLC) patients with VATS upper-lobectomy.Methods Between August 2012 and August 2014,100 NSCLC patients who had received VATS upper-lobectomy performed by a single surgeon were prospectively enrolled and randomly classified into a single-tube drainage group(A) and a two-tube drainage group(B),consisting of 49 and 51 patients respectively.Upper-lobectomy and systematic mediastinal node dissection or sampling were performed in all cases.Clinical and surgical variables were collected prospectively.Results There were no significant differences in demographic and pathologic features between two groups.The amount/duration of drainage,the postoperative hospitalization days,postoperative morbidity and mortality between two groups showed no significant difference either.Group A patients had significantly lower VAS pain scores in the second day (4.06 ± 0.97 vs 4.47 ± 0.86,P =0.027) and one month after surgery (1.31 ± 0.68 vs 1.61 ± 0.64,P =0.024)compared with group B patients.Conclusion Single-tube drainage is as safe and effective as the conventional use of two-tube drainage after VATS upper-lobectomy in NSCLC patients.Moreover,single-tube drainage can relieve the post-operative pain for the patients.

Objective To investigate the changes of the intervertebral angle and retrolisthesis of the last instrumented vertebrae (LIV) after anterior correction and instrumentation in adolescent idiopathic scoliosis patients. Methods By reviewing the medical records and roentgenograms of adolescent idiopathic scoliosis patients who underwent anterior correction and instrumentation in recent 4 years, their Cobb angle of the curve, correction rate, trunk shift, LIV rotation, obliquity between LIV and the pelvis, intervertebral angle and retrolisthesis of the LIV were measured and analyzed. Results There were total 50 patients included. The apex of the main curve was located at thoracolumbar junction or lumbar spine. The coronal Cobb angle of the main curve were 47.78??9.39? and 10.32??8.50? before and after surgery respectively, with an average correction rate of 79.05%. The average rotation of LIV before surgery was 1.54??0.58?, and improved to 1.06??0.47? after surgery. The obliquity between LIV and the pelvis before and after surgery were 23.80??7.91? and 9.16??9.46? respectively. The intervertebral angle was 3.72??3.05? before surgery, and -2.22??5.85? on Bending films, 1.56??5.97? after surgery respectively. The changes were of significance in the intervertebral angle after surgery compared with that before surgery(P=0.029). The angle was 4.87??7.95? at final follow up, the change was also significant compared with that after surgery(P=0.038). 19 patients had LIV retrolisthesis postoperatively, and the average retrolisthesis distance was (4.79?1.75) mm. There were significant differences between the patients with retrolisthesis and the patients without retrolisthesis in apical vertebral rotation and intervertebral angle on Bending films(P=0.047 and P=0.033) respectively. Conclusion The intervertebral angle is much improved after anterior correction and instrumentation surgery, but it increases gradually at follow up. The retrolisthesis of LIV may be correlated with the apical vertebral rotation before surgery and the intervertebral angle on Bending films.

Objective To investigate the feasibility and technique of combined endoscopic resection of esophageal carcinoma with VATS. Methods From April 2004 to November 2005, 32 patients with esophageal carcinoma underwent esophagectomy, including 10 cases by routin thoracotomy, 20 cases by 6cm thoracotomy associated with VATS and 2 cases by mediastinoscope and laparoscope. Gastric mobilization was performed with laparoscope in all patients. Results All the gastric mobilizations were successfully performed by laparoscope without blood transfusion. The number of removed celiac lymph nodes by laparoscopic surgery was 5.5?1.9. 20 patients underwent esophagectomy by minithoracotomy associated with VATS successfully, without conversion to open surgery. The number of removed mediastinal lymph nodes was 10.3?2.7. Postoperative complications included arrhythmia (4 patients), bleeding in chest (1 patient) and functional gastric obstruction (1 patient). 2 patients underwent esophagectomy by mediastinoscope and laparoscope successfully, no bleeding and no postoperative complications occurred. All patients were followed up from 1 to 20 months; no postoperative death and tumor recurrence were found. Conclusion Resection of esophageal carcinoma by laparoscope associated with VATS is a safe and feasible technique. The method of esophagectomy by minithoracotomy associated with VATS is wirth encouraged.

Objective To evaluate the clinical manifestation and the treatment strategy of the scoliosis associated with Chiari malformation and /or syringomyelia. Methods Fifty-two cases suffered from scoliosis with Chiari malformation and /or syringomyelia were divided into three groups for surgical treatment: 1) Group 1: 18 cases had scoliosis with Chiari Ⅰmalformation and /or syringomyelia without obvious neurologic impairment, their scoliosis was corrected with posterior instrumentation, but their Chiari Ⅰmalformation and syringomyelia were left untreated surgically. 2) Group 2: 12 patients, whose scoliosis was not indicated for surgery but those Chiari malformation associated with syringomyelia, underwent posterior sub-occipital craniectomy to enlarge foramen occipital magnum, C1 posterior arch decompression, duraplasty and syrinx-subarachnoid space shunting no matter whether neurologic deficits were present or not. 3) Group 3: 22 cases in addition of correction of scoliosis, due to neurologic deficits caused by Chiari Ⅰmalformation or syringomyelia, two-stage surgery was indicated: firstly, with posterior suboccipital craniectomy to enlarge foramen occipital magnum, C1 posterior arch decompression, duraplasty and syrinx-subarachnoid space shunting 6 months later, then underwent the scoliosis correction with instrumentation. Results In 34 patients who underwent craniovertebral decompression, only 6 of the 24 cases with preoperatively neurologic deficits achieved mild improvement within 6 months postoperatively. In 40 patients who were treated with posterior correction for scoliosis, the average frontal correction was 63% and the average sagittal correction was 80% for scoliosis less than 90?, the average frontal correction was 49% and the average sagittal correction was 74% for scoliosis more than 90?. At a follow-up of 6 months to 5 years, the average loss of the frontal correction was 6%. Conclusion Scoliosis associated with Chiari malformation and /or syringomyelia can be effectively treated with the similar results, as for adolescent idiopathic scoliosis. The mainstay for diagnosis is MR imaging. Accurate diagnosis and proper treatment for Chiari malformation or syringomyelia before scoliosis surgery will improve the rate of scoliosis correction, decrease the neurological complications.

Objective To evaluate the biomechanical basis and long term clinical outcome of the offset hook-screw combined instrumentation in preventing against correction loss after it is used to treat the unstable thoracolumbar fractures. Methods Of 98 cases treated with the offset hook-screw combined instrumentation from July 1997 to December 2002, 64 with follow-up over two years were reviewed. All 64 cases received operation within average 3.2 days after injury, of which 41 were fixated with CD or CD-Horizon instrumentation and 23 with TSRH instrumentation. The long term clinical outcome evaluation included the maintenance of the vertebral height restoration, the sagittal kyphotic Cobb angle loss and the coronal Cobb angle correction loss. Results No death occurred. But after operation, there was one case with worsened neurological deficits (recovered one week after surgery) and two with deep infection. The average post-operative vertebral height and the coronal Cobb angle were restored by 89.0% and 100.0% respectively and the sagittal kyphotic Cobb angle corrected from preoperative 31?to postoperative -1? . During the follow-up for 24-62 months, no instrumentation breakage occurred. The pseudoarthrosis was affirmed in one case and suspected in two with the vertebral height loss of 8.6% and the kyphotic Cobb angle correction loss of 4?respectively. Conclusions The offset hook-screw combined instrumentation can satisfactorily restore the normal sagittal profile, effectively prevent the fixation loosening or breakage, minimize the mechanical failure of instrumentation, and particularly reduce the loss of long-term correction.
