ABSTRACT
Secretory tumors of vasoactive intestinal polypeptides (VIPomas) are rare neuroendocrine pancreatic neoplasms usually associated with secretory diarrhea. Most cases present themselves with diarrhea, weight loss, and hypokalemia. Although VIPoma patients share easily distinguishable symptoms, early diagnosis remains a challenge. Therefore, tumors are usually found in large proportions and with later staging. The presenting case portrays a unique situation where the tumor found was still in a small size, is worth reporting it to the current literature. The diagnosis was made through laboratory evaluation and imaging studies. The primary treatment consists of exeresis surgery, but cytoreductive surgery also can provide several benefits. This way is necessary to pay attention to diagnoses also in the ways of treatment.
ABSTRACT
INTRODUCTION: The presence of a foreign body obstructing the bile duct may appear through a typical picture of cholangitis, usually caused by the presence of gallstones. PRESENTATION OF CASE: Male patient, 31 years old, involved an in accident with gunshot in 2006, injured in the abdominal region. Evolved to a picture of intense pain in the right hypochondrium, mainly after fat meals, without irradiation 12 years after being injured. Presented jaundice episode associated to fecal acholia, choluria, pruritus and sporadic fever. It was diagnosed cholangitis due to the foreign body like a bullet, located in the hepatic duct after tomography performed for investigation. The conduction of the case is described next. DISCUSSION: Cholestatic syndrome caused by gun bullet in a prior event to the symptoms is a rare event in the literature. Total, there are 8 case reports of bullets found in bile ducts with distinct evolution time among themselves. The first exam will not necessarily identify the bullet, but it simplifies the visualization of the bile ducts dilation, characterizing obstruction. CONCLUSION: The presence of a foreign body in the bile ducts is well reported in literature, and it is directly dependent on previous history. We should always avoid using cholangioresonance in dubious cases. To keep the ERCP as initial treatment is recommended due to the advances on the procedure quality, but in more severe cases or lack of resources, the surgical exploration is still indicated.
