ABSTRACT
Objective To discuss the clinical value of interventional management before surgical therapy for massive gastrointestinal hemorrhage, and to compare the clinical efficacy and re-bleeding rate between hypophysin infusion group and embolization group. Methods During the period of June 1998-Apr.2009, 31 patients with massive gastrointestinal hemorrhage in our institution underwent preoperative interventional managements before they received surgical treatment. According to DSA manifestations, the patients underwent trunsarterial hypophysin infusion or transcatheter embolization as interventional management. The clinical efficacy of interventional procedures and its influence on the surgery were evaluated, and the hemostasis rate and re-bleeding rate were compared the two kind of intervention managements. The numeration data were analyzed with Fisher's exact test, and the SPSS 11.0 was used as statistical software. Results The interventional managements were successfully performed in all the 31patients, with a total hemostasis rate of 83.9% (26/31) and a total re-bleeding rate 30.7% (8/26). The hemostasis rate and re-bleeding rate of hypephysin infusion group and embolization group were 69.2% (9/13), 94.4% (17/18) and 44.4% (4/9), 23.7% (4/17), respectively. All the 31 patients received surgery after interventional therapy, of which selective operation was carried out in 20. Neither surgery-related or intervention-related serious complications nor death occurred. Conclusion Preoperative interventional managements can provide patients with massive gastrointestinal hemorrhage with valuable chance of a successful surgery, enable the physician to take a selective operation to replace an emergency one, as a result, the surgical risk will be greatly reduced. Therefore, it is worth popularizing the preoperative interventional managements in clinical practice.
ABSTRACT
Objective To determine the clinical efficacy and safety of domestic biliary metallic stents in the management of biliary obstruction. Methods 75 domestic biliary metallic stents were implanted in 66 of 72 patients with obstructive jaundice due to malignant (n=70) and benign stenoses (n=2). Results The technical successful rate was 92.7% (64/66). Palliation with rid of jaundice was achieved in 96.9% (64/66) within 1 month. The 30-day mortality rate was 3% (2/66). Early complications occurred in 7.6% (5/66). 44 patients were followed from 2 to 24 months after treatment. 33 (33/42) of 42 patients with malignancy died after a median survival of 5.3 months (range 2-23 months). The remaining 9 patients (9/42) remained alive with a mean follow-up of 11.6 months. The stent patency rates were 92.8%,89.9% and 79.4% at 3,6,12 months respectively. 6 patients (6/42) presented stent occlusion within a median period of 3 months. One of two patients with benign stenoses sustained a patency duration time of 24 months. One patient died 3 months after treatment. Conclusions The domestic biliary metallic stent implantation is efficacy and safety in the management of biliary obstruction.
ABSTRACT
Objective To evaluate the efficacy of transcatheter lipiodol chemoembolization therapy (TOCE) for HCC via inferior phrenic artery (IPA) and to analyse the location of the tumor feeding inferior phrenic artey. Methods Twenty five cases of HCC underwent the procedure of TOCE via the IPA, as well as the hepatic artery using Seldinger's method. The patterns of tumor growth included huge type in 12 cases, solitary nodular type in 8 cases and multiple nodular type in 5 cases. Hepatic artery and inferior phrenic artery chemoembolizations were performed in all cases. Results Inferior phrenic artery originated from celiac trunk in 16 cases (64%); abdomen aorta around celiac trunck in 8(32%). The sitesot tumors supplied by IPA in right lobe (Ⅶ,Ⅷ segment) were 23 cases and left lobe (Ⅳ segment) 2 cases. The cumulative survival rates of IPA chemoembolization for hepatocellular carcinoma were 84%(1 year) and 68%(2 years). No severe complications occurred. Conclusions TOCE of the IPA is a safe and effective method in the management of HCC supplied by IPA. When the tumor site is adjacent to diaphragm, hepatic ligaments or bare area, may arouse the blood supply by IPA, especially in no tumor staining or staining defect in hepatic artery angiography but tumor enhancement on CT, and increase of the level of serum ? fetoprotein.
