Single-Institution Experience with Selective Internal Radiation Therapy (SIRT) for the Treatment of Primary and Secondary Hepatic Tumors.

PURPOSE: We aim to provide results of the real-world experience of a single center in Lebanon on the use of radioembolization to treat liver-only or liver-dominant tumors.  Methods: This retrospective review included patients who were evaluated for radioembolization between January 2015 and June 2017 and who had a lung shunt fraction of 20% or less. Tumor responses were determined using the response evaluation criteria in solid tumors (RECIST). RESULTS: Of the 23 Arab patients with a median age of 64 years (range, 36-87 years), eight had hepatocellular carcinoma, four had cholangiocarcinoma, and 11 had liver-only or liver-dominant metastases from other primary cancers. Most (n=17) had multifocal lesions, and 13 had a history of branched (n=8) or main (n=5) portal vein thrombosis. When appropriate, the gastroduodenal artery and middle hepatic artery were embolized for consolidation of radiotherapy; 18 patients required arterial coil occlusion, two had their cystic artery occluded, and one developed cholecystitis, which was successfully treated with antibiotics and supportive care. Another patient developed a post-radioembolization complication-a peptic ulcer unrelated to arterial reflux of microspheres because both the gastroduodenal and right gastric arteries were occluded. The median time to progression was seven months (range, 3-36 months), and median overall survival from radioembolization was 12 months (range, 3-40 months). Tumor responses included five complete responses, 13 partial responses, one stable disease, and four cases of progressive disease.  Conclusion: Performing radioembolization in a non-referral, private center in Lebanon resulted in good patient outcomes with few complications.

Resolution of late-onset gastro-colic fistula after laparoscopic sleeve gastrectomy by conservative management: a case report.

Nutritional support and Antibiotics treatment can be used as conservative treatment for the resolution of gastro-colic fistula after sleeve gastrectomy in stable patients specially to prevent cumbersome redo surgeries that have higher risks of complications particularly in patients with minimal financial means.

Reteplase infusion in the treatment of acute lower extremity occlusions.

PURPOSE: Reteplase, a recombinant tissue plasminogen activator, has been used in the treatment of acute coronary occlusion. Experience is accumulating regarding its use in the treatment of peripheral vascular disease. Increased experience with this thrombolytic agent may show that it can be an appropriate alternative agent to currently employed plasminogen activators. MATERIALS AND METHODS: Over the course of six months, reteplase was used to treat 18 patients with peripheral arterial occlusions, confined to the lower extremities. The agent was infused via "pulse-spray" catheters. Fifteen patients were started on 0.5 U/h. Concurrent heparin therapy was used at 500 U/h in 16 of 18 patients. RESULTS: The average total dose of reteplase infused was 13.3 units. It ranged from 6.2 to 41.5 units. The average duration of infusion was 26.9 hours with a range of 12-44 hours. Clinical success, defined as restoration of sufficient patency to reestablish limb function and resolution of pain in the symptomatic extremity was 89% (16 out of 18). Hemorrhagic complications occurred in five patients and were major in one patient (5%). No patient experienced intracranial hemorrhage. CONCLUSION: Increased experience with the use of reteplase in the treatment of acute lower extremity occlusions is accumulating. The safety and efficacy profile in our group appears satisfactory and compares to other studies. However, definite conclusions must await the results of controlled comparisons of different reteplase infusion regimens and controlled comparison to other thrombolytic agents.
