RESUMO
Backgrounds/Aims: While the effects of myosteatosis are emerging, the evidence for its use as a predictor of outcomes in patients undergoing pancreatoduodenectomy (PD) still needs to be established. The study aims to evaluate the effect of myosteatosis on the short- and long-term outcomes of PD. Methods: We analyzed the effect of myosteatosis on the short- and long-term outcomes of patients who underwent PD between July 2006 and May 2013. Myosteatosis was measured retrospectively from preoperative computed tomography (CT) at the L3 vertebra level, and dichotomized as a binary exposure variable as < 38.5 Hounsfield unit (HU) for males, and < 36.1 HU for females. Results: A total of 214 patient (median age 62 years, range: 41-80 years) CTs were analyzed for myosteatosis. Overall, 120/214 (56.1%) patients were classed as having myosteatosis. Both groups had similar comorbidity profiles. The presence of myosteatosis was not shown to increase the rate of any short- or long-term complication. However, pancreatic leak (29.8% vs. 13.3%; p = 0.006) and postoperative bleeding (13.8% vs. 5.0%; p = 0.034) were higher in the non-myosteatosis group. The median intensive care (2 days) and hospital stay (12 days) were the same in both groups. The 30-day mortality (myosteatosis: 3.3% vs. non-myosteatosis: 3.2%; p = 0.95), and 5-year overall survival (myosteatosis: 26.7% vs. non-myosteatosis: 31.9%; p = 0.5), were similar in both groups. Conclusions: We have found no evidence supporting myosteatosis affecting either the short-term or long-term outcomes of patients undergoing PD for suspected/confirmed malignant tumors.
RESUMO
BACKGROUND: Tumors occurring within the pancreatic head commonly arise from the pancreas, duodenal ampulla, distal bile duct, or duodenum. However, they are difficult to distinguish on standard preoperative imaging. PURPOSE: To assess the ability of specialist reporting of preoperative computed tomography (CT) scans to determine the organ of origin of pancreatic cancer (PC). MATERIAL AND METHODS: Blinded re-reporting of preoperative imaging from five hospitals was undertaken of a consecutive cohort of 411 patients undergoing surgery for PC between January 2006 and May 2014. Radiological identification of tumor site was determined by the presence of the main tumor bulk within the pancreatic head parenchyma and estimation of the pathological organ of origin of the PC was based on all the reported features. RESULTS: Each pathological tumor type was noted to have distinct radiological features. Localization of a visible tumor within the pancreatic parenchyma was seen most commonly in PC (92%) than other tumor types (P < 0.0001). Local invasion into the duodenum was a characteristic feature seen in 79% of patients with ampullary tumors and isolated dilation of the bile duct without dilation of the pancreatic duct was seen most commonly in patients with ampullary or bile duct cancer. In the assessment of tumor origin, good agreement (kappa = 0.6, 0.51-0.68) was noted between the consensus radiology opinion and the final histology result. Overall accuracy was greatest for ampullary cancer (88.1%) and lowest for PC (83.2%). CONCLUSION: Radiological assessment of preoperative imaging provides a high degree of accuracy in predicting the organ of origin of peri-ampullary cancer.

BACKGROUND: Accurate pancreatic and periampullary cancer staging with resectability assessment is vital to optimize surgical management and improve patient outcomes. The aim of this study is to assess the usefulness of a standardized reporting template. METHODS: Retrospective review of all surgically managed patients with pancreatic or periampullary malignancy between January 2018 and June 2019. Pre-operative CT imaging report was anonymised and audited against a modified NCCN reporting template. The same imaging studies were re-reported by two experienced GI radiologists using the same template. RESULTS: Fifty-nine patients (37 male) with median age of 68 years (36-83) underwent surgery for suspected pancreatic/peri-ampullary malignancy. The median time between pre-operative CT scan and surgery was 56.5 days (14-225). The use of reporting template resulted in significant increase in number of reported key features (p < 0.005), interobserver agreed features (p < 0.005) and overall k-value assessed interobserver agreement (p < 0.005). Template reports correlated closely with key intraoperative findings whilst primary free text reports did not (k-value 0.85-0.96 versus 0.20-0.46, p < 0.05). CONCLUSION: The use of a reporting template resulted in a more complete and accurate pancreatic/peri-ampullary tumour evaluation, improved inter-observer relatability and correlation with intraoperative findings.

Transverse testicular ectopia is a rare congenital anomaly in which both testes migrate along the same inguinal canal toward the scrotum. This report describes the case of the rarest form of transverse testicular ectopia in a 23-year-old man with coexisting testicular microlithiasis in one of the two testes as diagnosed on sonography and confirmed on MRI. We are unaware of any previous published reports of this association. Although the etiology of both conditions is debatable, each is believed to be associated with an increased risk of testicular malignancy, and this poses a dilemma for the future management of this patient.

Sub-trochanteric femoral fractures as a complication of long standing bisphosphonate therapy are rare. Drug regulatory authorities like MHRA in the UK (Medicines and Healthcare products Regulatory Agency) have recently alerted specialists about this complication. We describe and illustrate the plain radiographic, CT and MRI features and emphasize the role of imaging in the accurate diagnosis of this new type of insufficiency fractures. There is paucity of radiology literature on this topic and hence awareness of the typical imaging features helps to prevent misdiagnosis and delayed treatment. Our patients were on bisphosphonates (alendronate) for more than 3 years duration and presented with anterolateral thigh pain to the emergency department.
