Only few descriptions of intraoperative carcinoid syndrome (ioCS) have been reported. The primary objective of this study was to describe ioCS. A second aim was to identify risk factors of ioCS. We retrospectively analysed patients operated for small-bowel neuroendocrine tumour in our institution between 2007 and 2015, and receiving our preventive local regimen of octreotide continuous administration. ioCS was defined as highly probable in case of rapid (<5 min) arterial blood pressure changes ≥40%, not explained by surgical/anaesthetic management and regressive ≥20% after octreotide bolus injection. Probable cases were ioCS which did not meet all criteria of highly-probable ioCS. Suspected ioCS were detected on the anaesthesia record by an injection of octreotide due to a manifestation which did not meet the criteria for highly-probable or probable ioCS. A total of 81 patients (liver metastases: 59, prior carcinoid syndrome: 49, carcinoid heart disease: 7) were included; 139 ioCS occurred in 45 patients: 45 highly probable, 67 probable and 27 suspected. ioCs was hypertensive (91%) and/or hypotensive (29%). There was no factor, including the use of vasopressors, significantly associated with the occurrence of an ioCS. All surgeries were completed and one patient died from cardiac failure 4 days after surgery. After preoperative octreotide continuous infusion, ioCS were mainly hypertensive. No ioCS risk factors, including vasopressor use, were identified. No intraoperative carcinoid crisis occurred, suggesting the clinical relevance of a standardized octreotide prophylaxis protocol.

Objective: To describe a case of hepatic subcapsular hematoma causing an acute Budd-Chiari-like syndrome, leading to hepatic compartment syndrome, which combines compression of intrahepatic vessels on CT, acute liver failure, and refractory shock., Design: Case report., Setting: Surgical ICU of a university teaching hospital., Patient: Single case: A 64-year-old man hospitalized for 1 month in the ICU after multiple complications following bypass surgery, under anticoagulation after a recent aortic valve replacement and without a medical history of hepatic disease, underwent a percutaneous cholecystostomy for acute calculous cholecystitis. Fifteen days later, he presented with acute anemia, abdominal tenderness, severe hepatic cytolysis, metabolic acidosis, and hemodynamic dysfunction. CT showed a voluminous subcapsular hematoma compressing the hepatic parenchyma, which appeared ischemic with a flattened right lobar portal vein and vena cava without any visible active bleeding., Interventions: Arteriography and evacuation of the hematoma under ultrasound guidance (while managing hemodynamic dysfunction) were preferred to surgery given the patient's instability and surgical history., Measurements and Main Results: Evidence of vessels and parenchymal compression with no source of bleeding was found despite removal of the cholecystostomy catheter. Two right sectorial inferior hepatic arteries were embolized. Hematoma was punctured to relieve pressure on hepatic parenchyma, retrieving 300 mL of blood. Unfortunately, liver failure worsened dramatically while patient developed refractory shock and died., Conclusions: Hepatic compartment syndrome must be suspected when acute liver failure occurs in patients with subcapsular hematoma. Only early management may avoid a fatal outcome or the need for an emergency liver transplantation.

Introduction: We report a case of acute pulmonary renal syndrome mimicking septic shock, which led to the diagnosis of granulomatosis with polyangiitis., Case Report: A 70-year-old man was hospitalized because of acute kidney injury and acute respiratory distress syndrome with diffuse alveolar hemorrhage associated with a serum procalcitonin level of 18 μg/L. Initially, septic shock was suspected and antibiotic therapy was started. The absence of microbiological isolates and the patient's rapid clinical deterioration prompted laboratory testing for autoimmune disease, which confirmed the diagnosis of granulomatosis with polyangiitis. Immunosuppressive therapy was promptly initiated with corticosteroids, cyclophosphamide and several plasma exchanges, which resulted in a rapid clinical improvement and ICU discharge., Conclusions: Granulomatosis with polyangiitis is a systemic necrotizing vasculitis with antineutrophil cytoplasmic antibodies, which can present with acute pulmonary renal syndrome, combining acute respiratory distress syndrome and acute kidney injury. This misleading presentation must prompt an autoimmune disease testing in order to yield an early diagnosis of a vasculitis, allowing for timely initiation of immunosuppressive treatment. Serum procalcitonin levels can be markedly elevated and this must not override the possibility of a vasculitis where the patient shows a compatible symptomatology., (Copyright © 2014 SPLF.
