A 70-year-old man was admitted with upper abdominal pain. Endoscopic examination demonstrated early gastric cancer, which computed tomography and ultrasonography showed a 6cm infrarenal abdominal aortic aneurysm and bilateral common iliac artery aneurysms. The patient underwent distal gastrectomy, then 33 days later repair of the abdominal aortic aneurysm and bilateral common iliac artery aneurysms with a Dacron graft via a retroperitoneal approach. The patient had a good postoperative course. There have been many reports on the management of combined gastrointestinal malignancy with abdominal aortic aneurysm. We recommend two-stage operation except in patients at high risk of cardiac or pulmonary complications because of the minimum risk of graft infection, and consider that a retroperitoneal approach is good for aortic surgery in cases with a history of previous transabdominal operations.

Vascular trauma of the upper extremities is rare. We have successfully treated a case of laceration of the right subclavian artery induced by chest injury. A 45-year-old man with blunt trauma was admitted and angiography revealed laceration of the right subclavian artery. The injured area was exposed by a median sternal approach. The right common carotid-subclavian artery bypass was successfully performed with autogenous vein graft in less than three hours from admission. He recovered without any neurological deficit or functional disability and returned to his former occupation.

We report a case in which feelings of abdominal distension and discomfort of the abdominal wall caused by malignant ascites were relieved by ultrasound-guided rectus sheath block. Case report: A 59-year-old man developed gastric cancer with malignant ascites and experienced feelings of abdominal distension, but no nausea, dyspnea, poor mobility, or limb edema. Symptom control was inadequate with diuretic therapy and abdominal paracentesis. Feelings of distension improved temporarily with ultrasound-guided rectus sheath block. A percutaneous catheter was then used to administer an infusion of 0.25% ropivacaine triweekly until his death 20 days later. Conclusion: Feelings of abdominal distension is one of various symptoms of severe ascites and is difficult to manage. Ultrasound-guided rectus sheath block can be used to relieve this symptom on a case-by-case basis.

We report a case whose left lower limb neuropathic pain accompanied by pelvic tumor invasion was remarkably eliminated by ultrasound-guided sciatic nerve block. Case report: The subject was a sixty year old male. Pharmacological therapy was given according to the WHO analgesic ladder, but his left lower limb pain failed to respond to drugs. His intractable lower limb neuropathic pain was alleviated by ultrasound-guided sciatic nerve block. Drug delivery can be achieved with a percutaneous catheter and a disposable infusion pump. Infusions were run at 5mlh-1 with 0.1% ropivacaine. Conclusion: Neuropahic pain is sometimes hard to be controlled only by opioids or adjuvant analgesics, but there is a possibility of providing pain relief by combination use with nerve blocks. Interventional techniques can be highly effective but also have the potentiality to produce significant adverse effects. Many patients have factors which would be considered a near absolute contra-indication to the use of nerve blocks such as immuno-compromise or impairment of coagulation. Skillful application of peripheral neural blockade with ultrasound imaging broadens the options for providing optimal pain management. Palliat Care Res 2011; 6(1): 313-315

Objective: The development of hepatocellular carcinoma (HCC) is not uncommon in patients who achieve eradication of the hepatitis C virus through direct-acting antiviral (DAA) treatment. The aim of this study was to identify the patients at high risk for novel HCC development after a sustained virologic response (SVR) by DAA treatment.Patients and Methods: A total of 518 patients with no history of HCC treatment and who achieved SVR by DAA treatment were evaluated retrospectively. The correlations between HCC development and the patients’ characteristics were evaluated. For patients who underwent gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance imaging (MRI) or dynamic contrast-enhanced computed tomography, the relationship between the imaging findings and subsequent HCC development was also assessed.Results: HCC developed newly in 22 patients, and the 1-year and 3-year cumulative HCC rates were 2.0% and 8.5%, respectively. In multivariate analysis, a FIB-4 index >4.0 and a post-treatment α-fetoprotein >4.0 ng/ml were significant risk factors for HCC. In 26 of 118 patients who underwent an MRI before DAA treatment, a non-hypervascular hypo-intense nodule was seen in the hepatobiliary phase, and in 6 of 182 patients who underwent a CT, a non-hypervascular hypo-enhanced nodule was seen in the delayed phase. The sensitivity and specificity of the MRI-positive findings for the subsequent development of HCC were 0.92 and 0.87, respectively, and those of the CT were 0.40 and 0.99, respectively. In multivariate analysis of patients who underwent an MRI, a non-hypervascular hypo-intense nodule was the only factor that was significantly related to HCC development (HR 32.4, p = 0.001).Conclusion: Gd-EOB-DTPA-enhanced MRI was found to be reliable for risk evaluation of subsequent HCC development in patients after SVR by DAA treatment. Patients with a non-hypervascular hypo-intense nodule need more careful observation for incident HCC.

Objective: Combination therapy with glecaprevir and pibrentasvir (G/P) has been shown to provide a sustained virologic response (SVR) rate of >97% in patients with chronic hepatitis C virus (HCV) infection in the first published real-world Japanese data. However, a recently published study showed that the treatment was often discontinued in patients ≥75 years old, resulting in low SVR in intention-to-treat (ITT) analysis. Thus, our aim was to evaluate real-world data for G/P therapy in patients ≥75 years of age, the population density of which is high in “rural” regions.Patients and Methods: We conducted a multicenter study to assess the efficacy and safety of G/P therapy for chronic HCV infection, in the North Kanto area in Japan.Results: Of the 308 patients enrolled, 294 (95.5%) completed the treatment according to the protocol. In ITT and per-protocol analyses, the overall SVR12 rate was 97.1% and 99.7%, respectively. The old-aged patients group consisted of 59 participants, 56 of whom (94.9%) completed the scheduled protocol. Although old-aged patients tended to have non-SVR factors such as liver cirrhosis, history of HCC, and prior DAA therapies, the SVR12 rates in old-aged patients were 98.3% and 100% in the ITT and PP analyses, respectively. Of 308 patients enrolled, adverse events were observed in 74 patients (24.0%), with grade ≥3 events in 8 patients (2.6%). There was no significant difference in any grade and grade ≥3 adverse events between the old-aged group and the rest of the study participants. Only one patient discontinued the treatment because of adverse events.Conclusion: G/P therapy is effective and safe for old-aged patients.
