Objective: To evaluate the experience of surgical treatment of anastomotic recurrence following resection of esophageal carcinoma. Methods: Reoperation was performed in 11 patients with anastomotic recurrence. The surgical procedure performed included cervical esophagocolostomy in 5, cervical esophagogastrostomy in 3, esophagocolostomy and esophagogastrostomy at the top of chest in 2, respectively, and thoracotomy in 1. Results: There was one operative death with mortality rate of 9.1%. The cause of death was respiratory failure. 1-, 3-and 5-year survival rates were 77.8% (7/9), 44.4% (4/9) and 22.2% (2/9), respectively. Conclusion: Reoperation is still effective for some patients with anastomotic recurrence. Early diagnosis and prompt surgical treatment can improve the outcome.

This paper presents the experience of surgical treatment of 32 patients with esophageal stricture caused by corrosive burn. The modes of surgical treatment in this series included: instrumental dilatation in 11 cases, reconstruction with resection of strictured esophagus in 19 (pharyngogas-trostomy in 6, cervical esophagogastrostomy in 12 and colon interposition in 1) and reoperation for esophageal restenosis in 2, There was no operative morality. All patients were fol- lowed-up and 94% of them resumed their normal diet post-operatively. The author recommend that dilatation can be applied to patients with localized esophageal stricture or slight annular stricture, and should done early. Resection of the esophageal stricture and esophagal reconstruction can be used in patients with extensive or severe stricture. There are many ways to esophageal reconstruction. The optimal one should meet the following requirements: isoperistaltic segment without tension and rich in blood supply, it should be easy to perform and result in no restenosis.

Objective To evaluate the function of residual esophagus and stomach after subtotal esophagectomy and cervical gastroesophagostomy for esophageal carcinoma. Methods Manometry was performed in 21 patients who underwent cervical anastomosis after subtotal esophageal resection. The data was compared with normal subjects. Results The mean value of pharyngeal resting pressure was (1.20?2.03) mmHg(1mmHg=0.133kPa), and that of contraction pressure was (72.37?16.95) mmHg. The resting pressure of upper esophageal sphincter (UES) was (28.20?15.60) mmHg, and closing pressure was (107.10?28.43) mmHg. The resting pressure of residual esophagus was (15.98?11.10) mmHg, and contraction pressure was (48.45?18.37) mmHg. The resting pressure of stomach was (3.53?3.30) mmHg. Incidence of primary wave of esophagus was (57.14?34.50)%. The resting pressure of residual esophagus was much higher than that of normal group (P

Objective To establish an HPLC method for the content determination of protodioscin and diosgenin in Dioscoreae Hypoglaucae Rhizoma from different habitats.Methods The chromatographic separation was performed on an Agilent C18 column (4.6 mm×150 mm, 5μm) with mobile phase of acetonitrile-water solution with gradient elution at the flow rate of 0.8 mL/min; the detection wavelength was 208 nm; the column temperature was 30℃; the injection volume was 20μL.Results Protodioscin showed a good linear relationship among the range of 1.73–8.64 μg (r=0.999 6), with the average recovery of 101.98% (RSD=1.53%); Diosgenin showed a good linear relationship among the range of 1.03–8.20μg (r=0.999 1), with the average recovery of 101.60% (RSD=2.41%). The contents of protodioscin and diosgenin in Dioscoreae Hypoglaucae Rhizoma from 10 different habitats were in the range of 0.89%–2.24% and 0.75%–3.22%, respectively.Conclusion The method is simple, accurate and with repeatability, which can be used as quality control method of Dioscoreae Hypoglaucae Rhizoma.
