Purpose: Intravascular embolization of hemodialysis and central venous catheters is a rare but potentially serious complication. With the increasing use of catheters in medical practice, we are often faced with this type of complication. Novel, simple, and low-cost techniques are needed for foreign body extraction in order to reduce cardiovascular risks. Case Report: We describe the approach of 5 foreign body embolization cases. Case 1: a 57-year-old woman with end-stage renal failure with a complete fracture and migration of the distal extremity of a hemodialysis catheter. Case 2: a 55-year-old man with an accidental embolization of the distal portion of a hemodialysis catheter. Case 3: a 76-year-old woman with stage IV breast cancer and an accidental embolization of a central venous catheter guidewire. Cases 4 and 5: a 71-year-old woman and a 2-year-old boy with a port-a-cath embolization. All the patients underwent successful minimally invasive removal of the foreign bodies from the thoracic site using 5Fr pigtail catheters. Additional surgery was not required. No further complications, such as damage to the vascular wall, were noted. Conclusion: Our experience with the interlacing and traction pigtail show that it is a simple, practical, and low-cost technical alternative and its benefits should be widespread.

The present study showed high incidence of gallstone disease. Advanced stage adenocarcinoma was the most prevalent. This resulted in a low rate of operations with curative intent, in 30% of the patients, and a mortality rate of 21%. The appreciation of symptoms and early investigation by imaging could facilitate treatment in early stages of GC, providing a better prognosis for patients.

Synchronous tumors in both the rectum and the gallbladder are extremely rare. This study reports a case of gallbladder and rectal synchronic tumors, histopathologically confirmed, and discusses the therapeutic strategies in managing multiple primary cancers. Patient files from the Patient Files and Statistical Department of the University Hospital João de Barros Barreto and review of English literature were analyzed. Data from a case of a 69-year-old female patient with compressive vaginal and anal pain, constipation, and hematochezia were reviewed. Rectal touch evidenced a vegetating and infiltrative tumoral lesion, and colonoscopy demonstrated an elevated, vegetating, and infiltrative lesion. The histopathological analyses confirmed a moderately differentiated adenocarcinoma. A preoperative computer tomography scan was negative for metastasis investigation and, as an incidental finding, demonstrated cholelithiasis. The histological evaluation of the surgical specimens demonstrated rectal cancer, gallbladder cancer, and also hepatic metastasis. Due to the presence of hepatic and rectal cancer metastases, the standard management of the gallbladder cancer was modified according to the general concept that radical treatment of synchronous tumors should be reserved to situations were all tumors can be treated curatively or can improve life expectancy. Primary gallbladder and rectal synchronous neoplasms are rare and the treatment must be specific to each tumor, following the guidelines of each cancer whenever feasible. In case of metastasis or advanced stages of the disease, the treatment strategies must consider the most advanced tumor and/or the worst prognosis, and aggressive procedures must be avoided when it is not possible to radically treat every synchronous tumor.
