Treatment of malignant digestive tract obstruction by combined intraluminal stent installation and intra-arterial drug infusion

AIM: To study the palliative treatment of malignant obstruction of digestive tract with placement of intraluminal stent combined with intra-arterial infusion of chemotherapeutic drugs. METHODS: A total of 281 cases of digestive tract malignant obstruction were given per oral (esophagus, stomach, duodenum and jejunum), per anal (colon and rectum) and percutaneous transhepatic (biliary) installation of metallic stent. Among them, 203 cases received drug infusion by cannulation of tumor supplying artery with Seldinger's technique. RESULTS: Altogether 350 stents were installed in 281 cases, obstructive symptoms were relieved or ameliorated after installation. Occurrence of restenotic obstruction was 8-43 weeks among those with intra-arterial drug infusion, which was later than 4-26 weeks in the group with only stent installation. The average survival time of the former group was 43 (3-105) weeks, which was significantly longer than 13 (3-24) weeks of the latter group. CONCLUSION: Intraluminal placement of stent combined with intra-arterial infusion chemotherapy is one of the effective palliative therapies for malignant obstruction of the digestive tract with symptomatic as well as etiological treatment.

A clinical and long-term follow-up study of perioperative sequential triple therapy for gastric cancer

INTRODUCTIONAlthough the long-term postoperative survival rateof gastric cancer(GC) patients has been improvedsignificantly since the local dissection of lymph nodewas widely used in China,yet the low curativeresection rate and the high recurrence rate fromperitoneal and hepatic metastases hinder it fromfurther improvement.To alter the currentunsatisfactory status of GC treatment,a

A hybrid technique： intra-arterial catheter-directed thrombolysis following the recanalization of superior mesenteric artery in acute mesenteric ischemia

Acute mesenteric ischemia is a deadly process withoverall mortality rate of 40%. Acute thrombosis of an atherosclerotic lesion with previous partial occlusion isone of the common causes. Peri-operative mortality ofsuperior mesenteric artery （SMA） thrombosis is higherbecause of the difficulty in diagnosis,

Successful recanalization with multimodality endovascular interventional therapy in acute ischemic stroke

Stroke is an important cause of death and disability in adults. However, effective treatments for patients with acute ischemic stroke are limited. Intravenous recombinant tissue plasminogen activator(iv rtPA) within 4.5 h after onset has been approved as a standard treatment for patients with acute ischemic stroke. However, due to time constraints, less than one percent of acute ischemic stroke patients in Thailand are able to obtain iv rtPA. Although endovascular interventional therapy has not yet been approved as standard treatment in acute ischemic stroke, it is the one of the potentially effective treatment options. There are several reliable methods of endovascular therapy for acute ischemic stroke patients. Endovascular interventional therapy has rarely been done in Thailand. We report seven patients with successful recanalization after endovascular treatment in acute large vessel stroke from a single stroke center in Thailand. Patient screening and selection with multimodal imaging protocol and multimodality methods of endovascular interventional therapy are described.

Targeted Thrombolytic Therapy

Venous and arterial thrombosis are closely related to many severe diseases, especially to cardiovascular and cerebrovasular disorders. Thrombolytic therapy has been proven to be an effective method to treat such disease, which decreased the mortality and morbidity greatly.

Colorectal liver metastases:An update on multidisciplinary approach

Liver metastasis is the commonest form of distant metastasis in colorectal cancer.Selection criteria for surgery and liver-directed therapies have recently been extended.However,resectability remains poorly defined.Tumour biology is increasingly recognized as an important prognostic factor;hence molecular profiling has a growing role in risk stratification and management planning.Surgical resection is the only treatment modality for curative intent.The most appropriate surgical approach is yet to be established.The primary cancer and the hepatic metastasis can be removed simultaneously or in a two-step approach;these two strategies have comparable long-term outcomes.For patients with a limited future liver remnant,portal vein embolization,combined ablation and resection,and associating liver partition and portal vein ligation for staged hepatectomy have been advocated,and each has their pros and cons.The role of neoadjuvant and adjuvant chemotherapy is still debated.Targeted biological agents and loco-regional therapies(thermal ablation,intra-arterial chemo-or radio-embolization,and stereotactic radiotherapy) further improve the already favourable results.The recent debate about offering liver transplantation to highly selected patients needs validation from large clinical trials.Evidencebased protocols are missing,and therefore optimal management of hepatic metastasis should be personalized and determined by a multi-disciplinary team.

Twenty-eight Cases of Diabetic Foot Ulcer and Gangrene Treated with the Chinese Herbal Medicine Combined with Injection of Ahylsantinfarctase

Since 1995, the Chinese herbal medicine for supplementing qi and activating blood circulation combined with injection of ahylsantinfarctase into the femoral artery has been used in 28 cases of diabetes complicated with gangrene and ulcer of the foot, with quite good therapeutic effects as reported in the following.……
