RESUMO
BACKGROUND: Management of benign biliary strictures (BBS) post bilioenteric anastomoses requires a multidisciplinary approach including surgical, radiological, and/or endoscopic input. Patients often need multiple hospital visits for treatment with the long-term possibility of restenosis. Conventionally BBS have been treated with serial percutaneous transhepatic biliary dilatations necessitating repeat procedures for drain exchange or removal. Surgery may become necessary in refractory strictures. In the last decade, there have been increasing reports of the use of biodegradable stents (BDS) in treating biliary strictures mainly to address the need for repeated procedures for drain exchange. AIM: This study aimed to report the early outcomes in patients with BBS treated with BDS. METHODS: Retrospective analysis of prospectively collected data was performed in patients who had a bilioenteric anastomosis presenting with an anastomotic stricture and were intended to be treated with BDS. The primary endpoints reported were technical success (defined as a successful resolution of stricture on repeat cholangiogram) and clinical success (defined as the absence of repeated cholangitis). Clavien-Dindo (CD) grade of complication was reported. RESULTS: Twelve patients presented with BBS and nine patients had BDS. Three patients were not considered suitable for BDS due to a non-traversable stricture and had surgery. The male-female ratio was 1:2. There was 100% technical and clinical success with one patient having stent migration not needing intervention. The procedure took an average of 45 min. In seven (77.7%) patients, it was safely performed under local anesthesia with sedation. Two patients preferred general anesthesia. There was no restenosis noted at a median follow-up of 11 months. CONCLUSION: The use of BDS in the treatment of BBS is a safe and effective procedure. Longer-term follow-up with multi-institutional reporting on a national database is needed to assess its long-term benefits.
RESUMO
Visceral aneurysms are a well-recognized and potentially fatal occurrence in the event of rupture. Endovascular occlusion using stent grafting or embolization is often favorable over high-risk open surgical repair. However, interventional mesenteric angiography may not always be feasible or successful. We present an emergency case of successful occlusion of a large peripancreatic pseudoaneurysm using a single percutaneous injection of thrombin under ultrasound guidance alone after both laparotomy and mesenteric angiography had failed to identify and control bleeding. In this case and review of the current evidence, we propose an effective alternative first-line treatment strategy in these complex patients.
RESUMO
Endovascular aneurysm repair (EVAR) is now an established method of treating abdominal aortic aneurysms. Endovascular stent graft infection is a rare complication of EVAR. Diagnosis can be difficult and subsequent management challenging as a significant number of patients are unfit for further surgery and, untreated, graft infection is almost inevitably fatal. We present a case of an infected EVAR graft complicated by vertebral osteomyelitis that was treated conservatively. We discuss the diagnostic and therapeutic difficulties encountered and review the current literature on this evolving subject.
