100 patients involving Cervical Spinal Stenosis have been operated on from 10/1995- 9/1999 in the Spinal Surgery Dep. A Centre for Trauma- orthopedics in HCM city. The clinical data was as following: 32 cases involving Cervical Spondylosis; 63 cases involving Cervical Disc Herniation; 5 OPLL and CDH. Mean age: 49, 95 (29-76). Men: 69. Women: 31. 85 surgical interventions for 81 patients using Anterior Decompression and Fusion for one to three stages (4 reoperated cases: 2 epidural hematomas and 2 graf dislocations). 19 cases operated by posterior Approaches: two laminectomy, 17 using the KUROKAWA technique with four technical failure (turned to ITOH in two cases and lamiectomy in two cases). Grafting technique used: argenson 1, Bailey-Badgley 5, Bohlman 11, Bohlman and Kokubun 1, Kokubun 45, Kokubun for 2 different stages 1, Smith-Robinson and Kokubun for two different stages 1. Good fusion was obtained in all of the cases using the Anterior Decompression and Grafting. The recovery rate for whole group was 71% following the Scale of JOA. 71/87 cases accompanied by the neurological deficits recovered from motor weakness. Among them, there were 60,56% complete recovery, 39.44% partial recovery. 52/81 cases with anterior decompression and arthrodesis were followed between 3 to 39 months. 35 of them have been reviewed further 12 months. 11 of 19 cases operated by laminaplasty have been reviewed from 9 to 29 months. 9 of them with follow-up more than 12 months. Surgical treatment is really an effective method for Cervical Spinal stenosis. The skillfull surgical decompression techniques should be practiced.

To solve the problem of stent malapposition of intravascular stents, explore the design method of intravascular body-fitted stent structure and to establish an objective apposition evaluation method, the support and apposition performance of body-fitted stent in the stenotic vessels with different degrees of calcified plaque were simulated and analyzed. The traditional tube-mesh-like stent model was constructed by using computational aided design tool SolidWorks, and based on this model, the body-fitted stent model was designed by means of projection algorithm. Abaqus was used to simulate the crimping-expansion-recoil process of the two stents in the stenotic vessel with incompletely calcified plaque and completely calcified plaque respectively. A comprehensive method for apposition evaluation was proposed considering three aspects such as separation distance, fraction of non-contact area and residual volume. Compared with the traditional stent, the separation distances of the body-fitted stent in the incompletely calcified plaque model and the completely calcified plaque model were decreased by 21.5% and 22.0% respectively, the fractions of non-contact areas were decreased by 11.3% and 11.1% respectively, and the residual volumes were decreased by 93.1% and 92.5% respectively. The body-fitted stent improved the apposition performance and was effective in both incompletely and completely calcified plaque models. The established apposition performance evaluation method of stent considered more geometric factors, and the results were more comprehensive and objective.

We report the treatment of one patient with pharynx anastomotic stenosis after cervical esophagealresection by stent implantation. The patient suffered from serious pharynx anastomotic stenosis after gastric-pha-ryngeal anastomosis. After balloon-dilatation,a domestic self-expanding Z-stents was implanted in the stricture ofthe esophagus under the X-rays. After stent implantation, the patient has been leading a normal life for threeyears. Balloon dilatation and stent implantation is an effective and safe method in the treatment of patients withpharynx anastomotic stenosis.

This patient suffered from severe subglottic stenosis(grade Ⅳb). During partial cricotracheal resection, we cut through the cricothyroid membrane and the cricoid arch along the line from the lower edge of the thyroid cartilage to 5 mm of the inferior thyroid cartilage corner anteromedially. This can protect the cricothyroid joint, effectively protect the recurrent laryngeal nerve, and also support the airway. Strictly adhere to airway separation, avoid excessive separation of scars, and combine with reasonable postoperative management to achieve a safe extubation.

OBJECTIVETo summarize the experiences and advantages of laparoendoscopic single-site (LESS) surgery for neonatal intestinal atresia and stenosis.

METHODSTwenty patients of neonatal intestinal atresia and stenosis were treated with LESS procedure in Huai'an Women and Children's Hospital of Jiangsu Province between October 2010 and April 2012. The clinical data were retrospectively analyzed.

RESULTSAmong these patients, 13 were male, 7 were female. Age at admission ranged from 10 min to 1 d. Four cases were premature, and 3 were born with low birth weight (<2500 g). One was diagnosed with duodenal atresia, 1 with duodenal stenosis, 9 with jejunal atresia, 2 with jejunal stenosis, and 7 with ileal atresia. Laparoscopic exploration was performed in all the cases by transumbilical procedure, the proximal and distal ends were exteriorized from the umbilical port site for anastomosis. Twenty neonates with intestinal atresia and stenosis were performed using this new minimally invasive approach, with no cases converted to open operation or standard laparoscopy. The operative time was 35-60 (mean, 40) min. The intraoperative bleeding was 3-5 ml. Two cases were given up treatment by their parents on the second postoperative day. For the other 18 patients, oral intake started on postoperative day 5-10 (mean, 7), and discharged from hospital on the postoperative day 10-20 (mean, 13). The follow up ranged from 1 to 11 months, during which 1 case died, 3 cases were managed with conservative treatment for diarrhea or malnutrition. The other 14 cases grew up healthily.

CONCLUSIONThe technique of LESS in the treatment of neonatal atresia and stenosis is simple and the outcomes are satisfactory.

OBJECTIVE: To discuss the safety and efficacy of laparoscopic ureterovesical reimplantation in the treatment of transplanted ureteral stenosis. METHODS: One case of laparoscopic ureterovesicalre implantation in the treatment of ureteral stenosis after renal transplantation was reported, and related literatures was reviewed. A 54-year-old woman was admitted to our hospital with main complaint of hydronephrosis of transplanted kidney for five years after renal transplantation. Her physical examination showed slightly bulging in the transplanted kidney area without tenderness. The magnetic resonance urography (MRU) showed that the transplanted kidney and ureter were dilated obviously, with significant dilatation of renal pelvis and calyx, about 5 cm at the widest point of renal pelvis expansion, and the end of ureter was narrow, without abnormal filling defect in the ureter. The primary diagnosis was distal transplanted ureteral stenosis. After twice endoscopic ureteral dilatation by multi-endoscopic technique, there was no improvement in the hydronephrosis after the removal of the stent. After thorough preoperative preparation, laparoscopic ureterovesical reimplantation was performed under general anesthesia. Firstly, the median umbilical ligament, the lateral umbilical ligament and the peritoneal fold were cut off, and the anterior bladder space was dissociated distally. The space of left side wall of the bladder and the pubic bone was gradually dissociated, and the space of anterior bladder wall and the pubic bone was dissociated. Secondly, the right side wall of the bladder was dissociated from the head to the tail, and the surrounding structure was carefully identified to avoid injury of the ureter of the transplanted kidney. The transplanted ureter was sought between the right side of the bladder and the lower pole of the transplanted kidney. The distal end of the ureter was cut open, and the narrow section was cut off, confirming that no stenosis in the proximal ureter. The ureterocystic anastomosis was performed by Lich-Gregoir method (extra-bladder). Finally, the bladder tissue around the anastomosis site was fixed to the right pelvic wall to reduce tension. RESULTS: The operation was completed successfully, the operation time was 210 min, the amount of bleeding was about 30 mL, and there was no surgical complication. The creatinine was stable after operation, with serum creatinine declining to 68 μmol/L, and serum creatinine 94 μmol/L before operation. The patient was discharged 5 days after operation. After follow-up of 3 months, KUB indicated that the position of ureteral stent was good and the function of renal transplantation was stable. CONCLUSION Laparoscopic ureterovesical reimplantation is a safe and effective treatment for ureteral ureteral stricture after renal transplantation. Compared with open surgery, laparoscopic surgery has less impact on renal renal allograft, with faster recovery, less bleeding, fewer complications, less postoperative pain and minimally invasive wound. This surgical procedure is difficult and requires an experienced urologist with high laparoscopic skills to perform.

OBJECTIVE: To evaluate the effects of endoscopy-assisted sialodochoplasty for the treatment of severe sialoduct stenosis with concurrent megaducts. METHODS: From Jul.2010 to Dec. 2016, 8 patients presenting with severe parotid duct stenosis and 3 patients with occlusion of the Wharton's duct underwent endoscopy-assisted sialodochoplasty.All these patients had concurrent severe ductal ectasiaand manifested a painful swelling of the involved salivary glands.The diameter of ectasia and length of stenosis of the sialoducts were measured preoperatively by sialography, computed tomography, or ultrasonography. The megaducts were opened transorally and sutured to the buccal or oral floor mucosa, therefore creating a neo-ostium. All the patients were followed up periodically after operation. The treatment effects were evaluated by clinical signs, sialogram and sialometry. RESULTS: The length of the Stensen's duct stenosis was 5-12 mm, and the diameter of the concurrent ectasia was 8-16 mm. The length of the Wharton's duct stenosis was 10-20 mm, and the diameter of the concurrent ectasia was 6-8 mm.The neo-ostiums healed uneventfully 2 weeks after operation. The duration of the follow-up varied from 6 to 78 months (median: 24 months). Among the 8 patients with Stensen's duct stenosis, two experienced re-obliteration of the neo-ostium, but the buccal bulge and clinical symptoms disappeared; one reported recurrent clinical symptoms after initial alleviation, which could be controlled with self-massaging; the remaining 5 patients had satisfactory clinical results, i.e., disappearance of the obstruction symptoms and buccal bulge, patent ostium,clean saliva and improvement of the ductal ectasia on sialogram. Three patients with Wharton's duct occlusion were asymptomatic with clear saliva and patent ostium;two exhibited approximately normal appearance and one showed improvement of the sialogram.Sialometry was performed in 9 patients with patent neo-ostium of the involved glands,the resting saliva flow rate of the affected glands showed no differences compared with the normal side, and stimulated flow rate showed a significant increase, though less than the control side.The clinical results included good in 5 patients, fair in 4 patients, and poor in 2 patients, with a total effective rate of 82% (9/11). CONCLUSION Endoscopy-assisted sialodochoplasty appears to be effective and can be a viable option for patients presenting with severe sialoducts tenosis and concurrent ectasia.

OBJECTIVES: To study the role of bronchoscopy in slide tracheoplasty. METHODS: A retrospective analysis was conducted on the diagnosis and treatment of four children with tracheal stenosis admitted to Hunan Provincial People's Hospital from 2017 to 2020. The role of bronchoscopy was summarized in the preoperative evaluation, intraoperative positioning and measurement, and postoperative wound evaluation and treatment during slide tracheoplasty. RESULTS: Bronchoscopy evaluation before slide tracheoplasty showed that 3 of the 4 children had complete trachea rings, 2 had pulmonary artery sling, and 2 had multiple stenosis. Slide tracheoplasty was performed in the hospital on 3 children, and the midpoint of the stenosis segment was judged under bronchoscopy, and the length of the stenosis segment was measured, which assisted in the resection of the stenosis segment of the trachea. The pathogens were identified by lavage after the surgery. One child who developed scar traction 9 months after slide tracheoplasty in another hospital was improved by interventional treatment under bronchoscopy. Mucosal changes were found under bronchoscopy in 2 children 4 days after surgery, and the treatment plan was adjusted. One month after surgery, 2 children had granulation hyperplasia, which was improved by cryotherapy under bronchoscopy. One child abandoned treatment due to anastomotic necrosis and died. Three survivors were followed up for over 6 months with good prognosis, but all had tracheobronchial malacia. CONCLUSIONS Bronchoscopy can be used for the management of slide tracheoplasty in children with tracheal stenosis, which is helpful to postoperative rehabilitation and follow-up.
