Objective To explore the feasibility and safety of endoscopic thyroidectomy via chest-breast approachand summarize the operation skill. Method The clinical data of 40 cases performed endoscopic thyroidectomy via chest-breast approach from August 2010 to August 2012 in this hospital were analyzed retrospectively. Results The endoscopic thyroidectomies via chest-breast approach were successfully performed in all 40 patients without conversion to open surgery， massive haemorrhage， hypercapnia， severe subcutaneous emphysema， cutaneous necrosis on chest，permanent impairment of recurrent laryngeal nerve， and permanent hypoparathyroidism. One case of hoarseness was found on 2d after operation， who returned to normal after symptomatic treatment. One case of numbness in the extremitieshappened on day 2 after operation and the symptom was relieved through intravenous and oral administration of calcium treatment in 3d. One case of cutaneous tightness on chest happened， and it was spontaneous remission in a month. The operation time was （102±28.4） min （55-182 min）， intraoperative bleeding was （46±16.6） mL （30-106 mL）， and the drainage tube was removed postoperative 2-7d with an average （4±2.2） d， the postoperative hospitalization was 3-8 d with an average （4±1.1） d. All of the cases were followed-up after operation without low calcium， low parathyroid hormone， hoarseness， and local goiter recurrence. Two cases of hypoparathyroidism returned to normal after oral thyroxine dose adjustment. All the patients were satisfied with the cosmetic results. Conclusions The endoscopic thyroidectomy via chest-breast approach is safe and feasible with good cosmetic results. The subcutaneous Y tunnel， the “upper yellow middle white lower red” appearance on the chest， and the landmark of inverse trapezium on the neck are the key points for creation of operation compartment. Sufficient exposure， stepwise procedure， blunt dissection combined with sharp dissection in the precise gap are the surgical skills for endoscopic thyroidectomy.
ObjectiveTo evaluate the high-level disinfection effect of flexible endoscopes in the Endoscopy Center of the First People’s Hospital of Longquanyi District of Chengdu, explore the key links of flexible endoscope cleaning and disinfection, and provide theoretical guarantee and technical support for the next step of the endoscope center work.MethodsWe sampled and monitored the lumens, water and air injection ports and biopsy ports of 19 flexible endoscopes after high-level disinfection in the Endoscopy Center of the First People’s Hospital of Longquanyi District of Chengdu. A total of 307 specimens were collected from 108 flexible endoscopes. We compared the disinfection effects of different flexible endoscopes and different sampling sites, and compared the microbial detection status of different flexible endoscopes.ResultsThe qualified rates of disinfection of gastroscopes, colonoscope and duodenoscopy were 79.22%, 86.21% and 100.00%, respectively, and the difference was not statistically significant (P=0.721). The qualified rates of disinfection of the endoscopic lumen, water and air injection port and biopsy port were 87.04%, 93.00% and 94.95%, respectively, and the difference was not statistically significant (χ2=4.585, P=0.101). The qualified rates of the lumen, water and air injection port and biopsy port of gastroscope, colonoscope and duodenoscope were 84.42%, 93.10%, 100.00%, 92.96%, 92.59%, 100.00%, 94.29%, 96.30%, 100.00%, respectively. There was no statistically significant difference in the disinfection effect of various parts of different flexible endoscopes (P>0.05). Bacteriological identification showed that of the 28 specimens with excess bacteriological standards, 16 gram-positive bacteria (57.1%), and 12 gram-negative bacteria (42.9%) were found.ConclusionThe cleaning and disinfection effect of flexible endoscopes has certain defect. Endoscope should be treated in strict accordance with the technical specifications for cleaning and disinfection of the flexible endoscope to further improve the disinfection effect of the flexible endoscope.

The number of patients with pancreatic pseudocyst suitable for endoscopic therapy was increasing. When pancreatic pseudocyst was accompanied with complication, polycystic or failed in endoscopic treatment, surgical intervention was the only choice. Endoscopic technique would be considered firstly in other conditions.ConclusionIndividual scheme should be advocated according to the size, number location and complication of the pancreatic pseudocyst.
【Abstract】 Objective To evaluate the detection and localization of obscure lower gastrointestinal bleeding by using SPECT/CT and intraoperative endoscopy. Methods Twenty-six cases of patients with obscure lower gastrointestinal bleeding were analyzed retrospectively. Results The positive detection rate of SPECT/CT was 88.5%. All 26 patients (100%) were identified the bleeding source by using intraoperative endoscopy. No recurrence was found during 1-24 months follow-up. Conclusion SPECT/CT examination should be chosen firstly for patients with obscure lower gastrointestinal bleeding in order to localize the bleeding site roughly. Intraoperative endoscopy can localize the bleeding site accurately in patients who undergoes operation.
ObjectiveTo observe the clinical effect of retrograde lacrimal intubation under endoscope in the treatment of chronic dacryocystitis. MethodsWe retrospectively analyzed the clinical data of 83 patients (103 eyes) with chronic dacryocystitis treated in our department from March 2011 to January 2013. They underwent retrograde lacrimal intubation under endoscope. The postoperative follow-up continued 9 months and the curative effect was observed. ResultsEighty-eight eyes were cured, accounting for 85.44%; improvement occurred in 10 eyes, accounting for 9.71%; five eyes were not cured, accounting for 4.85%. As a result, the total effective rate was 95.15%. ConclusionRetrograde lacrimal intubation under endoscope is a safe and effective surgical method for the treatment of chronic dacryocystitis.
Objective To introduce the current status of clinical research on endoscopic cholecystolithotomy with reservation of gallbladder. Methods Literatures related to the basis, advantage, indication, contraindication, operative method and current controversy were reviewed and summarized. Results The objective evidences were afforded by postoperative complications of cholecystectomy for endoscopic cholecystolithotomy with reservation of gallbladder. The progress of endoscopic technique made it possible for reservation of gallbladder. The controversy in endoscopic cholecystolithotomy with reservation of gallbladder was focused on the choice of indications and operative procedure. Incorrect patient selection and undue pursuit of cholecystolithotomy with reservation of gallbladder would be completely opposite to the treatment of gallstone. Conclusion It is feasible for endoscopic cholecystolithotomy with reservation of gallbladder to remove completely stone and reserve gallbladder function, but further investigation and long-term follow up are required to delineate gallstone recurrence after operation.
Objective To summary the change of surgical approaches, indications, contraindications, and complications of endoscopic thyroidectomy. Methods Endoscopic thyroidectomy related literatures at home and abroad were collected to summary the change of surgical approaches, indications, contraindications, and complications of it. Results The approaches of endoscopic thyroidectomy had their own advantages, wherein breast and complete areola approaches were mainstream surgical procedures; the indications were closely correlated with surgeons and devices, and there were no uniform indications yet. With the advance in endoscopic techniques, the contraindications would be gradually resolved, and the assistance of new devices and the accumulation of experience reduced the incidence of surgical complications, but there were still probability of occurrence of such complications. Conclusion Endoscopic thyroidectomy is the main means of treating thyroid nodules, which will be more widely used with the advance in techniques, the innovation of devices, the expansion of indications as well as the overcoming of contraindications.
ObjectiveTo investigate short-term outcomes and surgical techniques of endoscopic saphenous vein harvesting (ESVH) for coronary artery bypass grafting (CABG). MethodsClinical data of 554 patients undergoing CABG with ESVH in General Hospital of Shenyang Military between July 2009 and August 2013 were retrospectively analyzed. There were 372 male and 182 female patients with their age of 38-84(61.3±9.0) years. Clinical outcomes, postoperative lower extremity pain and edema, wound infection and healing were analyzed. ResultsDuring ESVH, 13 patients with very little subcutaneous fat received transition to skin bridge technology or partially open incision. Average number of harvested vein grafts was 1-4 (2.0±0.6), and the quality of the vein grafts was satisfactory. Postoperative lower extremity pain and edema were significantly reduced, and there was no delayed wound healing or infection. Seven patients died postoperatively, including 2 patients with perioperative myocardial infarction, 2 patients with pneumonia, 1 patient with ventricular fibrillation, 1 patient with massive cerebral infarction, and 1 patient with multiple organ dysfunction syndrome. A total of 452 patients were followed up for 120-1 460 (742.6±188.5) days. There was no late death or reintervention during follow-up. ConclusionESVH is a safe and efficacious procedure with less postoperative lower extremity pain and edema, satisfactory vein graft quality, better postoperative recovery and cosmetic results, compared with traditional fully or intermittently open wound for saphenous vein harvesting.
ObjectiveTo know the fundamental status of painless digestive endoscopy in China. MethodsA 23-item survey including multiple choices and fill-in-the-blank questions on 3 pages was performed on anesthesiologists in China excluding Taiwan, Macao and Hong Kong on www.xqnmz.com and www.dxy.cn/bbs from November 1 to December 31, 2013, among which 5 questions were on personal details, 9 on hospital and department, and 9 on clinic details. The results about the basic facts, risk factors of anesthesia and drug use and monitoring of painless digestive endoscopy in China were analyzed. ResultsA total of 726 questionnaires were collected, among which 667 (91.87%) were considered valid. Interviewed hospitals included hospitals from 31 provinces, municipalities and autonomous regions excluding Taiwan, Macao and Hong Kong. Thirty questionnaires were from the first-grade hospitals (4.5%), 292 from the second-grade (43.78%), and 345 from the third-grade (51.72%). And 69.12% of the questionnaires showed these hospitals could only carry out painless gastroscopy and/or colonoscopy, while 80.81% showed the number of the mean painless endoscopy cases was 0-30 per day; 47.23% of the respondents working in digestive endoscopy center had to complete the anesthesia procedure alone, and 35.83% of the respondents illustrated their digestive endoscopy centers had established the post anesthesia care unit; 62.97% were equipped with anesthesia apparatus or ventilator; 89.96% were equipped with tracheal intubation tool; and 21.44% were equipped with defibrillator. Among them, 25.79% did not prepare rescue medicines regularly in digestive endoscopy center. Propofol was the most frequently used anesthetic, and composited fentanyl was at the highest use rate for gastrointestinal endoscopy. Respondents who used electrocardiogram, non-invasive blood pressure and pulse oxygen saturation the least to monitor during painless gastroscopy and colonoscopy took up 43.48% and 46.08% respectively. ConclusionPainless digestive endoscopy needs further development and standardization with the regulation of related guidelines and standardized residents training.
