Percutaneous endoscopic gastrostomy/jejunostomy combined with percutaneous transhepatic biliary drainage in treating malignant biliary obstruction

To investigate the safety and efficacy of percutaneous endoscopic gastrostomy/jejunostomy [PEG/PEJ] combined with percutaneous transhepatic biliary drainage [PTCD] in treating malignant biliary obstruction. Nine patients [6 males and 3 females, average age 71.3 +/- 5.5 years] with complete obstruction of the biliary tract were treated with PEG/PEJ after PTCD. The PEG/PEJ and PTCD tubes were linked outside of the abdominal wall to direct the externally drained bile back to the jejunum through the PEG/PEJ intestinal tube. Clinical symptoms and liver function were assessed following the treatment. The operations were successfully completed in the 9 patients within 40 min [average 35 +/- 2.9 min]. Clinical symptoms such as jaundice, abdominal distension, stomachache and diarrhea appeared but improved within 7 days of the operation. Serum levels of bilirubin, aspartate aminotransferase and alanine aminotransferase were reduced [p < 0.01] 4 weeks following the treatment. There were no procedural complications. Combined PEG/PEJ and PTCD appeared to be safe and effective in the management of malignant biliary obstruction. Further, larger-scale studies will be needed to verify findings of this report

Ultrastructural changes of duodenal mucosas and their significance in patients with liver cirrhosis / 中华肝脏病杂志

<p><b>OBJECTIVE</b>To investigate the ultrastructural changes of duodenal mucosas and their significance in patients with liver cirrhosis (PLC).</p><p><b>METHODS</b>Endoscopic biopsy duodenal mucosa specimens of 60 PLC and 18 healthy volunteers as controls were obtained. Ultrastructural changes of them were studied with transmission electron microscopy. These PLC were divided into groups A, B and C according to the Child-Pugh classification. The ultrastructural changes in the duodenal mucosas of each group were rated and compared with those of the other groups. PLC with and without ultrastructural changes of duodenal mucosas were divided into a positive group and a negative group. Levels of plasma Alb, TBil, PT, plasma endotoxin, and blood ammonia of the PLC were detected and compared.</p><p><b>RESULTS</b>There were 20 PLC each in groups A, B, and C. Ultrastructural changes of duodenal mucosas were found in 5 PLC of group A, 9 in group B and 17 in group C. Among the 60 PLC, 52% had some changes in their duodenal mucosas. The changes included decrease and rupture of the microvilli; also karyopyknosis, karyorrhexis, widening of the gaps of the tight junction and tumefactions of mitochodrion of duodenal mucosa epithelial cells. No ultrastructural changes of duodenal mucosas were found in the control group. The rate of changes in the three Child-Pugh class groups and in the control group were 25%, 45%, 85%, 0% respectively (P < 0.01). The level of Alb of the positive group was significantly lower than that of the negative group (P < 0.01). Levels of plasma TBil, PT, endotoxin and blood ammonia of the positive group were significantly higher or longer than those of the negative group (P < 0.01). Levels of plasma Alb of the positive and negative groups were significantly lower than those of the control group (P < 0.01). Levels of TBil, PT, plasma endotoxin and blood ammonia of the positive and negative groups were significantly higher or longer than those of the control group (P < 0.01).</p><p><b>CONCLUSION</b>There were ultrastructural changes of duodenal mucosas in PLC, especially in end-stage PLC. Ultrastructural changes of intestinal mucosas in the PLC may have important pathophysiological and clinical significance.</p>
