ABSTRACT
Anastomotic cicatricial stenosis after resection of esophageal cancer were treated by self- making electric knife through endoscipe.Fifty two cases were located in upper segment while 37 cases in middle-lowere part.Anastomotic diameter of 40 cases were less than 2.0mm,17 cases less than 3.0mm. Sixteen cases more than 3.0mm. Anastomotic stoma were incarcerated by food in 16 cases.The operatic procedure:First,the cicatricial stenosis was resected and became"*"shape by electric knife,then dilated by baloon catheter and by endoscope.sitytwo cases of stenosis were unobstrated(can swallow solid food)after one time treatment ; 11 cases each needed 2 and 3 times;1 case each needed 4 , 5 , 12 , 43and 81 times ,respec- tively. The last 2 cases were treated repeatly every 1- 3 months. The authors think that this procedure is ef- fective and safe. The technique is mastered easily and could be wildely used.
ABSTRACT
Urinary excretion of prostaglandin E2. (PGE2) and thromboxane B2 (TXB2, a stable metabolite of TXA2), atrial natriuretic peptide (ANP) and arginine vasopressin (AVP) in plasma were determined with radioimmunoassay in 30 healthy normal controls (NC) and 53 cirrhotic patients without asoites (n = 18), with ascites (n = 25) and with hepatorenal syndrome (HRS, n=10). All of four vasoactive substances in the group of cirrhotic patients without ascites were significantly higher than that in NG (P
