Abstract: ［Abstract］ Objective〖HTSS〗〓To study the clinical value of continued outofhospital management in patients with malignant high biliary obstruction(MHBO) after implantation of biliary extradrainage tube(BEDT), providing reasonable suggestions to reduce the incidence of outofhospital complications during BEDT.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓120 patients with MHBO after implantating BEDT, were randomly divided into control group and experimental group. 60 cases in the control group received routine management, visiting the hospital regularly. On the basis of conventional management, another 60 cases in the experimental group received continued outofhospital management to prevent the relative complications of BEDT. The incidence and management of complications of BEDT implatation in the two groups outside the hospital were compared.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓Outside hospital, the overall complication rate of BEDT in the control group was significantly higher than that in the experimental group with statistically significance(P＜005), including displacement、prolapsus、obstruction of BEDT and biliary tract infection. The hospital referral of patients in the control group was higher than those in the experimental group（P＜005). Because the patients in the control group did not regularly sluice biliary tract, nor regularly change surgical dressing and drainage pack, and they did not record the color and capacity of drainage. 32 cases(53.3%) of the control group were rehospitalized due to complications of BEDT outside hospital, which included 7 cases in the experimental group(11.7%). The difference was statistically significant(P＜005).
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓In order to fundamentally solve the brought outside the hospital during BEDT complications, prevention was the most important. Continued outofhospital management could reduce incidence of BEDT complications, improve the use of BEDT time and usage rate, reduce the patient's health service cost, which was worthy of clinical application. The prevention and continued outofhospital management are the keys to fundamentally resolve and reduce the beset produced by complications of BEDT. Also, continued outofhospital management improves the usage of BEDT and reduces the health service cost of patients, worthy of generalized clinical application.
