ABSTRACT

PURPOSE: A preoperative estimate of the risk of malignancy for intraductal papillary mucinous neoplasms (IPMN) is important. The present study carries out an external validation of the Shin score in a European multicenter cohort. METHODS: An observational multicenter European study from 2010 to 2015. All consecutive patients undergoing surgery for IPMN at 35 hospitals with histological-confirmed IPMN were included. RESULTS: A total of 567 patients were included. The score was significantly associated with the presence of malignancy (p < 0.001). In all, 64% of the patients with benign IPMN had a Shin score < 3 and 57% of those with a diagnosis of malignancy had a score ≥ 3. The relative risk (RR) with a Shin score of 3 was 1.37 (95% CI: 1.07-1.77), with a sensitivity of 57.1% and specificity of 64.4%. CONCLUSION: Patients with a Shin score ≤ 1 should undergo surveillance, while patients with a score ≥ 4 should undergo surgery. Treatment of patients with Shin scores of 2 or 3 should be individualized because these scores cannot accurately predict malignancy of IPMNs. This score should not be the only criterion and should be applied in accordance with agreed clinical guidelines.

ABSTRACT

There are many different types of mediastinal masses, which makes it challenging to diagnose them. Furthermore, the clinical presentation can range from asymptomatic to life-threatening. We present the case of a 68-year-old male with an incidental finding of a tumor located in the anterior mediastinum. A computed tomography (CT) of the thorax and an 18-Fluorodeoxyglucose positron emission tomography (PET) suggested a thymoma, which is the most common primary tumor of the anterior mediastinum. The patient was scheduled for a robotic-assisted thoracoscopy (RATS) thymectomy. Both this procedure and the postoperative course were uneventful. The pathology report showed multiple cholesterol granulomas in the mediastinal fat. Furthermore, no malignancy (e.g. a thymoma) could be found. A cholesterol granuloma mimicking an anterior mediastinal tumor is extremely rare.

ABSTRACT

BACKGROUND: Hepatectomy remains the most important treatment modality for most malignant liver tumors. Vascular involvement stays a reason for unresectability or major parenchymal resection. A possible way to avoid this is parenchymal-sparing hepatectomy (PSHX) with vascular resection and reconstruction (HVRR). In this article, we aim to demonstrate the specific role of this technique in avoiding post-hepatectomy liver failure (PHLF). METHODS: A retrospective analysis of 10 patients who underwent HVRR was conducted. 99mTechnetium-mebrofenin hepatobiliary scintigraphy (HBS) was used to predict the future liver remnant function (FLRF). Calculations were made for each patient to compare HVRR and major hepatectomy (with or without portal vein embolization). RESULTS: In our cohort, there was no perioperative mortality. Two patients suffered a Clavien-Dindo grade 3a complication and none had clinically significant PHLF. Estimated FLRF was significantly higher in HVRR compared to major hepatectomy after portal vein embolization (p < .005). CONCLUSIONS: Instead of focusing on inducing liver remnant hypertrophy, preserving parenchyma through HVRR can be an interesting treatment strategy. It can be performed with an acceptable operative risk. Calculations of FLRF (using HBS) suggest that this approach is able to reduce the risk for PHLF and related morbidity or mortality.
