Endoscopic sinus surgery is effective to nasal sinus mucocele with eye symptoms as main manifestation. It is very importment to raise the awareness of the disease and to prompt imaging examination. Three cases were reviewed. One mucocele was found in the frontal sinus ethmoid sinus,1 in the fronto-ethmoid sinus and 1 in the spheno-ethmoid sinus. All cases were preoperatively diagnosed by CT, MRI or intranasal endoscopy. Nasal sinus mucocele with eye symptoms as main manifestation should be early diagnosed. Endoscopic sinus surgery is a safe and effective method for the treatment of nasal sinus mucocele,and could be the primary choice for it. All cases were treated by nasal endoscopic sinus surgery. The majority of symptoms, such as exophthalmos, epiphora and diplopia, disappeared in all patients. However, vision recovery was observed only in some patients.

Objective To explore clinical effect of choledocholithotomy by laparoscopy-assisted choledochoelectroscopy and endoscopic retrograde cholangiopancreatography.Methods The clinical data of 126 gallstone and choledocholithiasis patients treated by laparoscopy-assisted choledochoelectroscopy(L group)and endoscopic retrograde cholangiopancreatography(E group)were analyzed retrospectively.In L group,the patients were performed LC and choledocholithotomy by laparoscopy-assisted choledochoelectroscopy directly,but in E group,the treatment procedures were finished by two steps.Firstly,the bile duct stones were carried out by ERCP,days later LC operations were performed.Between the two groups,the hospital days,costs,the rate of residual stone,the rate of bihary infection or panereatitis and the rate of stone recur were compared.Results In the two groups,hospital days were(6.5±0.3)d and(12.5±0.5)d,costs were(1.22±0.17)and(1.98±0.24)ten thousand yuan,the rate of residual stone was 0 and 5.3%,the rate of biliary infection or pancreatitis was 1.4%and 15.8%,and the rate of stone recur was 1.4%and 10.5%respectively.When compared each other the difference was statistically significant(t=2.48,1.96,χ2=4.32,4.90,8.79,all P＜0.05).Conclusion In patients with gallstone and bile duct stones,laparoscopy-assisted choledochoelectroseopy presented more predominances when compared with two steps methods.

Objective:To study the diagnosis value of Transcranial Doppler ultrasound for intracranial artery stenosis in patients with cerebral infarction.Methods:A total of 140 patients with acute cerebral infarction,transient ischemic attack and posterior circulation ischemic attack in Department of Neurology,Xinjiang cardiovascular and cerebrovascular disease hospital from October 2014 to October 2016 were selected as research object,CT angiography (CTA) and TCD detection were performed in all patients.Used CTA examination results as the gold standard,the detection results of intracranial artery stenosis in two groups were compared,the diagnostic value of TCD and the diagnostic results of TCD to the degree of bilateral middle cerebral artery (MCA) stenosis were analyzed.Results:CTA diagnosis showed that 140 patients had a total of 105 patients with intracranial artery stenosis,in the anterior and posterior circulation vessel of 1155 intracranial segments,CTA detection showed that 249 vessels were narrow,TCD detection showed that 236 vessels were narrow.Com-pared with CTA,TCD was better in the diagnosis of patients (Kappa value＞0.75).The diagnostic sensitivity and positive predictive value of TCD for MCA were the highest,which were 91.26％ and 93.07％,the consistency was the best (Kappa value =0.917).CTA detection showed that 210 MCA vessels had 103 stenoses,mild stenosis 17,moderate stenosis 41,severe stenosis 45,TCD detection showed that the stenosis was 101,mild stenosis 16,moderate stenosis 40,severe stenosis 45.The Kappa test showed that the diagnostic results of TCD to the degree ofMCA stenosis was better consistency compared with CTA (Kappa value=0.884.Conclusion:TCD has a high diagnostic value for cerebral artery stenosis in patients with cerebral infarction,and it is consistent with the diagnosis of CTA.

OBJECTIVE: To investigate the diagnosis and treatment of esophageal perforation and neck abscess induced by esophageal foreign body and to make a better solution for the disease. METHOD: Twenty-four cases with esophageal perforation and neck abscess induced by esophageal foreign body treated in our department were surgery under general anesthesia. The foreign bodies were removed via esophagoscope in 14 cases, thorocomy in 3 eral neck incision in 5; and no foreign bodies were found in 2 cases. RESULT: There were 16 cases complicated by abscess. Among these complications,there were 10 cases of periesophageal abscess,4 cases of neck abscess and 1 case of mediastinal abscess. In 24 patients, 21 cases cured and one died. One case was sent to the department of endocrinology because of hyperglycaemia and two cases were sent to the department of thoracic surgery for further treatment. CONCLUSION Early diagnosis and treatment is the key to the management of esophageal perforation induced by esophageal foreign body. Thin-section CT has a high value for the diagnosis and differential diagnosis in such patients. Once deep neck abscess is diagnosed, an early abscess surgical drainage, an appropriate antibiotics and a nutrition supporting treatment are effective for the patients.

OBJECTIVE: To investigate the efficacy of endoscopic nasal cavity expansion surgery on obstructive sleep apnea hypopnea syndrome (OSAHS) and nasal obstruction. METHOD: Clinical data of 48 OSAHS patients with structural abnormality in nasal cavity treated in our department were retrospectively analysed. These patients received endoscopic nasal cavity expansion surgery and were observed for the relief of both subjective and objective symptoms. RESULT: PSG was reexamined 12 months postoperatively. Of all the patients, 29 cases (60.4%) showed complete recovery, 10 cases (20.8%) showed remarkable improvement of the symptoms, 4 cases (8.3%) exhibited curative effect and 5 cases (10.4%) were of no effect, respectively. The symptoms of apnea, hypopnea, LSaO2 and somnolence were significantly improved in all patients,and nasal congestion was obviously relieved. The improvement of snore was not evident. CONCLUSION Endoscopic nasal cavity expansion surgery is effective and safe for the treatment of OSAHS mainly due to nasal obstruction. Operation should be performed to correct structural abnormality in nasal cavity and adjust symmetric distribution of nasal airflow on both sides in order to maintain normal ventilation function. The procedure is applicable to OSAHS patients accompanied by nasal congestion and upper airway resistance syndrome and personalized adjustment is beneficial for better clinical efficacy according to the condition of different patients.

OBJECTIVE: To investigate the therapeutic effect of revision endoscopic sinus surgery for recurrent chronic rhinosinusitis. METHOD: Clinical data of 45 cases of recurrent rhinosinusitis treated in our hospital were retrospectively analyzed. Revision endoscopic sinus surgery was performed in all the patients. RESULT: All the patients were followed up for a period of 1 to 2 years after operation. No serious complication occured. The cure rate was 75.6% (34 cases), 8 cases (17.8%) improved, while other 3 cases (6.6%) were of no effect. CONCLUSION Recurrent rhinosinusitis is closely related with medical treatment before the surgery, adhesion in nasal cavity after the surgery, deviation of nasal septum, treatment of superior turbine and inferior turbine and regular medicament management after the surgery. Revision endoscopic sinus surgery is an effective method for recurrent recurrent rhinosinusitis. The efficacy of revision endoscopic sinus surgery can be greatly improved by reasonable perioperative management, skilled operation and regular follow-up postoperatively.
