Objective To evaluate the effect and feasibility of balloon dilatation for treatment of anastomotic stricture after biliary-intestinal anastomosis with percutaneous transhepatic cholangial drainage( PTCD) .Methods A total of 23 pa-tients with anastomotic stricture after biliary-intestinal anastomosis who had undergone PTCD+balloon dilatation were ana-lyzed retrospectively between Mar 2009 to Dec 2011.The patency of bile duct, jaundice index and liver function were recor-ded.Results PTCD+balloon dilatation was completed successfully in all cases, and a metallic stent was implanted in one case.Anastomotic stricture, postoperative jaundice index and liver function were improved significantly after operation.No serious complications occurred.Conclusion PTCD+balloon dilatation has good curative effect on anastomotic stricture. The complication rate is low.It is a safe, feasible and effective minimally invasive treatment.

The aim of this study was to establish a high performance liquid chromatography-mass spectrometry method for the determination of 5-(4′-(bromomethyl)-［1, 1′-biphenyl］-2-yl)- 1H-tetrazole(BBT1)and 5-(4′-(dibromomethyl)-［1, 1′-biphenyl］-2-yl)-1H-tetrazole(BBT2), which are two genotoxic impurities in olmesartan medoxomil. Chromatographic separation was based on an Agilent Zorbax Eclipse Plus C18(250 mm × 4. 6 mm, 5 μm)column using water(containing 0. 1% formic acid)- acetonitrile as mobile phase in gradient elution mode. Mass spectrometry was operated in positive ion mode. Selective ion monitors were set at m/z 315 for BBT1 and at m/z 395 for BBT2. Good linear correlations were observed in the range of 0. 009 4- 0. 561 0 μg/mL(r=0. 998)with the quantification limit at 9. 35 ng/mL and the detection limit at 3. 12 ng/mL for BBT1, and in the range of 0. 018 2- 0. 547 5 μg/mL(r=0. 999)with the quantification limit at 18. 25 ng/mL and the detection limit at 6. 08 ng/mL for BBT2. Furthermore, the average recoveries of the three spiked concentration level were 96. 5%(n=9, RSD=4. 8%)and 98. 0%(n=9, RSD=5. 1%)for BBT1 and BBT2, respectively. The proposed method is simple, specific and accurate, and quite suitable for the determination of BBT1 and BBT2 in olmesartan medoxomil.

Objective:To evaluate the curative effect of non-surgical treatment of acute upper gastrointestinal perforation and analyze the risk factors.Methods:We retrospectively reviewed medical records of patients who were diagnosed with acute upper gastrointestinal perforation from Jan 2016 to Dec 2018 in Liaocheng People's Hospital. At first, all patients were put on non-surgical treatment. According to whether or not converted to surgery, they were divided into non-surgical treatment group (163 cases) and surgery group (29 cases). Univariate analyses and multivariate analyses were conducted.Results:192 patients with acute upper gastrointestinal perforation were cured without serious complications and death. The non-surgical treatment efficiency was 84.9%. The onset time ( OR=0.238, P=0.046), heart rate ( OR=1.043, P=0.004), serum albumin ( OR=0.869, P=0.002) are independent risk factors. Conclusion:Non-surgical treatment of acute upper gastrointestinal perforation is safe and effective. Onset time, heart rate and serum albumin are independent risk factors. In patients when time of onse t>12h, heart rate >100 beats/min, hypoalbuminemia, and high level of procalcitonin , conversion to surgery should be considered.

Esophagopulmonary fistula is a rare disease in clinic, most esophagopulmonary fistula is diagnosed and treated because of typical cough symptoms after eating or drinking. This case reported no typical symptoms of choking and coughing in eating or drinking water, patients with intermittent hemoptysis for nearly 30 years were diagnosed with bronchiectasis, Because of massive hemoptysis for emergency operation, the esophagus and the left lower lung were found to have abnormal muscular conduits during the operation, so diagnosis of esophagopulmonary fistula.

Objective To summarize clinical outcomes of subxiphoid uniportal video-assisted thoracoscopic surgery for bilateral chest diseases simultaneously. Methods The clinical data of 60 patients with bilateral chest diseases treated by uniportal thoracoscopic surgery via subxiphoid approach in the Department of Thoracic Surgery, Affiliated Hospital of Zunyi Medical College from August 2016 to December 2017 were retrospectively analyzed. There were 35 males and 25 females, aged 25.5±8.8 years ranging from 13 to 51 years. There were 40 patients wtih palmar hyperhidrosis, and 20 patients with bilateral pulmonary bullae and onset of one-side pneumothorax. All patients adopted subxiphoid uniportal video-assisted thoracoscopic surgery. Among them 36 patients with palmar hyperhidrosis underwent resection of R3 bilateral sympathetic nerves, 1 resection of R4 bilateral sympathetic nerves, 3 resection of R3+R4 bilateral sympathetic nerves, and 20 patients with pulmonary bullae underwent bilateral bullectomy and pleurodesis. Results Fifty-five patients cured within 1 to 4 days and discharged after surgery. One patient with incision infection and pulmonary infection after bullectomy, cured and discharged after 3 weeks anti-inflammation and incision dressing change. Four patients with Grade B healing recovered after 1 to 2 weeks dressing change. During the follow-up, no pneumothorax or hand perspiration relapsed. Conclusion Subxiphoid uniportal video-assisted thoracoscopic surgery for simple bilateral chest disease simultaneously is safe and feasible, which not only avoids simultaneous trauma of bilateral punch, but also alleviates the pain of patients.
