The clinical analysis of upper gastrointestinal rehaemorrhagia after transjugular intrahepatic portasystemic shunt / 中国医师进修杂志

ABSTRACT

Objective To study the pathogenesis of upper gastrointestinal rehaemorrhagia after the transjugular intrahepatic portasystemic shunt (TIPS) and its influencing factor.Methods Fifty postoperative patients with TIPS were selected.The patients were followed-up,and the effect of the various factors in the role of upper gastrointestinal rehaemorrhagia after TIPS was analyzed.Results The portal vein pressure of 50 patients with TIPS decreased from preoperative (39.8 ±9.2) cmH2O (1 cmH2O =0.098 kPa) to postoperative (25.2 ± 5.8) cmH2O,and there was statistical difference (P ＜ 0.05).Fourteen patients appeared upper gastrointestinal rehaemorrhagia after TIPS,which accounted for total of 28％ (14/50) and included 3 cases of postoperative vomiting blood within 3 days.Acute stomach mucosa lesions bleeding was considered,and bleeding was controlled within a short-term medical treatment (1 patient after more than a year in recurrent upper gastrointestinal rehaemorrhagia).Twelve cases of patients appeared upper gastrointestinal rehaemorrhagia within 2 years after TIPS,and the causes of rehaemorrhagia in 6 cases were esophageal variceal rehaemorrhagia,gastric and duodenal ulcer in 3 cases,erosive gastritis in 2 cases,coagulation abnormalities in 1 case.Esophageal variceal rehaemorrhagia rate was 12％ (6/50).Conclusions The main reasons of upper gastrointestinal rehaemorrhagia after TIPS are variceal rehaemorrhagia and non variceal rehaemorrhagia,both of which are important causes of rehaemorrhagia after TIPS.Variceal rehaemorrhagia after TIPS occurs more than 3 months,and non variceal rehaemorrhagia occurs within 3months,so it is very important to protect gastric mucosa with proton pump inhibitor in postoperative patients.
