ABSTRACT
BACKGROUND: In response to the pandemic, the International Hepato-Pancreato-Biliary Association (IHPBA) developed the IHPBA-COVID Registry to capture data on HPB surgery outcomes in COVID-positive patients prior to mass vaccination programs. The aim was to provide a tool to help members gain a better understanding of the impact of COVID-19 on patient outcomes following HPB surgery worldwide. METHODS: An online registry updated in real time was disseminated to all IHPBA, E-AHPBA, A-HPBA and A-PHPBA members to assess the effects of the pandemic on the outcomes of HPB procedures, perioperative COVID-19 management and other aspects of surgical care. RESULTS: One hundred twenty-five patients from 35 centres in 18 countries were included. Seventy-three (58%) patients were diagnosed with COVID-19 preoperatively. Operative mortality after pancreaticoduodenectomy and major hepatectomy was 28% and 15%, respectively, and 2.5% after cholecystectomy. Postoperative complication rates of pancreatic procedures, hepatic interventions and biliary interventions were respectively 80%, 50% and 37%. Respiratory complication rates were 37%, 31% and 10%, respectively. CONCLUSION: This study reveals a high risk of mortality and complication after HPB surgeries in patient infected with COVID-19. The more extensive the procedure, the higher the risk. Nonetheless, an increased risk was observed across all types of interventions, suggesting that elective HPB surgery should be avoided in COVID positive patients, delaying it at distance from the viral infection.

INTRODUCTION: Inflammatory pseudotumor of spleen is an extremely rare benign condition of uncertain etiology that presents with nonspecific symptoms or as an incidental finding in patients studied by other processes. Since the first description in 1984 by Cotelingam and Jaffe, only 114 cases have been reported. PRESENTATION OF CASE: We present a case of a fifty-six years old woman with a splenic injury in ultrasound and computed tomography. The patient undergoes laparoscopic splenectomy and the histologic study of the specimen revealed findings consistent with inflammatory pseudotumor of spleen. DISCUSSION: This rare entity whose pathogenesis is still unknown, can present with nonspecific symptoms. Radiologic studies may lead the diagnosis being useful CT and MRI. The definitive diagnosis is established with the histological findings, characterized by the presence of inflammatory cells with areas of necrosis and fibrosis. There are multiple differentials diagnoses: metastasis, lymphoma, splenic infarction, hemangiomas, vascular malformations, lymphangioma, plasmacytoma, reactive lymphoid hyperplasia, abscess and infectious granulomatous processes; therefore suspicion of malignant neoplasm must be considered, being indicated splenectomy to confirm the diagnosis. CONCLUSION: Inflammatory pseudotumor of spleen is a benign disease, in which diagnostic approach must bear in mind the possibility of a malignant lesion. For this reason, the surgical approach is appropriate to confirm the diagnosis and rule out malignancy with histology.
ABSTRACT
INTRODUCTION: Granulocytic sarcoma (GS) is an extramedullary disease which is composed of immature myeloid cells or myeloblasts and usually occurs in association with acute myeloid leukemia (AML), as an initial presentation or a relapse. GS has been associated with various cytogenetic abnormalities, particularly with the t(8;21) translocation and less frequently the inv(16) type. CASE PRESENTATION: We present a rare case of GS of the small bowel, greater omentum and peritoneum, which caused obstruction, in a patient with AML associated with a CBFß/MYH11 fusion gene and an inv(16) (p13q22). In this patient there was only mild myeloid hyperplasia in bone marrow aspiration but molecular analysis identified a CBFß-MYH11 fusion and inv(16) (p13;q22). CONCLUSION: Because of its nonspecific clinical and radiologic findings, this entity can be misdiagnosed and can mimic other solid neoplasms, making it a diagnostic challenge. In a GS with no or minimal morphological changes in bone marrow aspiration it is very important to perform a cytogenetic analysis to benefit from the diagnosis and therapeutic strategy.
