RESUMO
BACKGROUND: Anticoagulant therapy with heparin is the first-line treatment for acute mesenteric vein thrombosis and is effective in improving outcomes. Conversely, patients with failed early anticoagulant therapy occasionally develop bowel infarction requiring surgery. The efficacy of long-term anticoagulant therapy on recanalizing mesenteric vein thrombosis in patients with failed early anticoagulant therapy remains unclear. Herein, we report a patient who achieved recanalization of port-superior mesenteric vein thrombosis treated with anticoagulant therapy for 10 years after failed early anticoagulant therapy, followed by bowel resection. CASE PRESENTATION: A 38-year-old male patient visited an outpatient clinic due to acute exacerbation of abdominal pain that had persisted for a month. He was diagnosed with port-superior mesenteric vein thrombosis on contrast-enhanced computed tomography (CT) scan and was transferred to our institution. Although he presented with abdominal pain, his respiration and circulation were stable upon hospital arrival. Anticoagulant therapy with heparin was started, and the patient was admitted to the intensive care unit. However, the patient's abdominal pain worsened, and he began to develop signs of peritonitis. Repeat CT scan revealed bowel infarction. Thus, the patient underwent bowel resection 6 h after admission. The initial surgery was completed with open abdomen management. Bowel anastomosis was performed on the second-look surgery on the first postoperative day. Finally, the abdomen was closed on the third postoperative day after confirming the absence of bowel ischemia progression. The patient had prolonged impaired bowel function with paralytic ileus, but was discharged on the 60th postoperative day. He was then diagnosed with protein C and S deficiency based on the tests performed. Anticoagulant therapy with warfarin was initiated. He also received anticoagulant therapy in the outpatient setting. The patient's port-superior mesenteric vein thrombosis had improved gradually with warfarin during the follow-up period. At 10 years after surgery, total occlusion of the port-superior mesenteric vein was recanalized with improvement of the portal collateral vessels. In addition, no gastric or esophageal varices were observed. CONCLUSIONS: Long-term anticoagulation therapy could affect the recanalization of extensive thrombus in multiple segments in patients with mesenteric venous thrombosis.
RESUMO
BACKGROUND: A team approach is essential for effective trauma management. Close collaboration between interventional radiologists and surgeons during the initial management of trauma patients is important for prompt and accurate trauma care. This study aimed to determine whether trauma patients benefit from close collaboration between interventional radiology (IR) and surgical teams during the primary trauma survey. METHODS: A retrospective observational study was conducted between 2014 and 2021 at a single institution. Patients were assigned to an embolization group (EG), a surgery group (SG), or a combination group (CG) according to their treatment. The primary and secondary outcomes were survival at hospital discharge compared with the probability of survival (Ps) and the time course of treatment. RESULTS: The analysis included 197 patients, consisting of 135 men and 62 women, with a median age of 56 [IQR, 38-72] years and an injury severity score of 20 [10-29]. The EG, SG, and CG included 114, 48, and 35 patients, respectively. Differences in organ injury patterns were observed between the three groups. In-hospital survival rates in all three groups were higher than the Ps. In particular, the survival rate in the CG was 15.5% higher than the Ps (95% CI: 7.5-23.6%; p < 0.001). In the CG, the median time for starting the initial procedure was 53 [37-79] min and the procedure times for IR and surgery were 48 [29-72] min and 63 [35-94] min, respectively. Those times were significantly shorter among three groups. CONCLUSION: Close collaboration between IR and surgical teams, including the primary survey, improves the survival of severe trauma patients who require both IR procedures and surgeries by improving appropriate treatment selection and reducing the time process.

In the treatment of diabetes mellitus, there is a growing trend towards using high-concentration insulin, with Lantus XR (Bridgewater, NJ: Sanofi-Aventis U.S. LLC), which has a drug concentration three times higher than that of conventional Lantus (100 U/mL; Bridgewater, NJ: Sanofi-Aventis U.S. LLC), being a prominent example. This type of high-concentration insulin is known for its smaller injection volumes, leading to a slower absorption rate and maintenance of more consistent blood insulin levels. When administered in high doses, the pharmacological effects of insulin are generally prolonged; however, insulin glargine overdose rarely occurs, and its pharmacokinetics remain unclear. We encountered a case of an insulin overdose in a 19-year-old female patient, who had self-injected glargine (Lantus XR) 1,350 units and aspart (NovoRapid; Bagsværd, Denmark: Novo Nordisk A/S) 600 units. We measured blood glucose and insulin levels over time. Bimodal peaks in blood insulin levels were observed, and we adjusted high doses of intravenous infusion with a 50% glucose solution until the blood insulin levels returned to the normal range. Consequently, the patient was treated without inducing severe hypoglycemia. U300 glargine overdose may lead to both a multimodal elevation in blood insulin levels and prolonged hypoglycemia compared to U100 glargine. Therefore, monitoring blood insulin levels and adjusting treatment accordingly may contribute to safer patient management. This study represents the initial documentation of blood insulin levels measured in a U300 glargine overdose patient, revealing a bimodal peak.
RESUMO
PURPOSE: The purpose of this study was to examine the survival benefits of a workflow in which an interventional radiology (IR) team participates in a primary trauma survey on patients with hemodynamically unstable trauma. MATERIALS AND METHODS: A retrospective observational study was conducted between 2012 and 2019 at a single institution. Patients who underwent an IR procedure as the initial hemostasis were assigned to the hemodynamically stable group (HSG) or hemodynamically unstable group (HUG). The primary and secondary outcomes were survival at hospital discharge compared with the probability of survival (Ps) and the time course. RESULTS: A total of 160 patients (100 men, 60 women; median age, 57.5 years [interquartile range (IQR): 31.5-72 years]) with an injury severity score of 24 (IQR: 13.75-34) were included. A total of 125 patients were included in the HSG group and 35 patients in the HUG group. The observational survival rate was significantly greater than the Ps rate by 4.9% (95% confidence interval [CI]: 1.6-8.4%; P = 0.005) in HSG and by 24.6% in HUG (95% CI: 16.9-32.3%; P < 0.001). The observational survival rate was significantly greater than Ps in HUG than in HSG (P < 0.001). The median time to initiate IR procedures and the median procedure time in HUG were 54 min [IQR: 45-66 min] and 48 min [IQR: 30-85 min], respectively; both were significantly shorter than those in the HSG. CONCLUSION: A trauma workflow utilizing an IR team in a primary survey is associated with improved survival of patients with hemodynamically unstable trauma when compared with Ps with a shorter time course.

AIM: The mortality rates among elderly patients with open abdomen (OA) are high, and pre-existing comorbidities could affect the outcomes. However, long-term prognosis remains uncertain. We examined long-term outcomes in elderly patients with OA, focusing on physical functional status. METHODS: We undertook a retrospective cohort study between 2007 and 2017 at a single institution. Patients with OA who were aged ≥65 years were categorized into two groups: "good preoperative functional status" group (GFG) and "poor preoperative functional status" group (PFG). The GFG was defined as Eastern Cooperative Oncology Group/World Health Organization performance status (PS) 0-1, whereas PFG was defined as PS 2-4. The primary outcomes were survival and PS 2 years following the initial surgery. RESULTS: Of the 53 participants, 38 and 15 were assigned to the GFG and PFG, respectively. The PFG (median age, 81 years) was older than the GFG (median age, 75.5 years; P = 0.040). The 2-year survival rate was 39.5% in GFG and 6.7% in PFG, and Kaplan-Meier analysis showed significant difference (P = 0.022). Among all patients, the PS at 2 years was worse than that at discharge (P = 0.007). Preoperative PS was correlated with 2-year survival (P = 0.003), whereas age and pre-existing comorbidities were not. CONCLUSION: The long-term outcomes of elderly patients with OA are affected by the preoperative physical functional status. Functional status deteriorates in a time-dependent manner. Therefore, surgery requiring OA must be carefully considered for elderly patients with PS 2 or higher.
RESUMO
CONTEXT: Lymphoepithelial cysts of the pancreas show various presentations on imaging studies often making a differential diagnosis difficult. CASE REPORT: A 58-year-old man was admitted to our hospital with epigastric discomfort and abdominal bloating. Abdominal US was carried out and demonstrated a cystic lesion 5 cm in diameter which included an intracystic projection into the pancreatic body. This intracystic projection was also seen on CT and MR images. On FDG-PET images, the projection was positively visualized. Since we could not exclude a pancreatic cystic neoplasm, a distal pancreatectomy was performed. Postoperative pathological examination demonstrated that the lesion was a lymphoepithelial cyst of the pancreas. There were no atypical cells in the intracystic projection. CONCLUSION: Resection is inevitable when a true pancreatic neoplasm cannot be excluded.
