| 1 | Pulmonary embolism after arterial chemoembolization for hepatocellular carcinoma: An autopsy case report显示文摘We report an extremely rare case of pulmonary lipiodol embolism with acute respiratory distress syndrome(ARDS) after transcatheter arterial chemoembolization(TACE) for hepatocellular carcinoma(HCC). A 77-yearold man who was diagnosed with a huge HCC wasadmitted for TACE. Immediately after the procedure, this patient experienced severe dyspnea. We suspected that his symptoms were associated with a pulmonary lipiodol embolism after TACE, and we began intensive treatment. However, his condition did not improve, and he died on the following day. A subsequent autopsy revealed that the cause of death was ARDS due to pulmonary lipiodol embolism. No cases have been previously reported for which an autopsy was performed to explain the most probable mechanism of pulmonary lipiodol embolism; thus, ours is the first report for such a rare case. | Keiichi Hatamaru Shunjiro Azuma Takuji Akamatsu Takeshi Seta Shunji Urai Yoshito Uenoyama Yukitaka Yamashita Kazuo Ono | 2015 | World Journal of Gastroenterology2015，21，4： | 5 |

| 3 | Ileus caused by cholesterol crystal embolization: A case report显示文摘Cholesterol crystal embolization(CCE) is a rare systemic embolism caused by formation of cholesterol crystals from atherosclerotic plaques. CCE usually occurs during vascular manipulation, such as vascular surgery or endovascular catheter manipulation, or due to anticoagulation or thrombolytic therapy. We report a rare case of intestinal obstruction caused by spontaneous CCE. An 81-year-old man with a history of hypertension was admitted for complaints of abdominal pain, bloating, and anorexia persisting for 4 mo. An abdominal computed tomography revealed intestinal ileus. His symptoms were immediately relieved by an ileus tube insertion, and he was discharged 6 d later. However, these symptoms immediately reappeared and persisted, and partial resection of the small intestine was performed. A histopathological examination indicated that small intestine obstruction was caused by CCE. At the 12-mo follow-up, the patient showed no evidence of CCE recurrence. Thus, in cases of intestinal obstruction, CCE should also be considered. | Shunjiro Azuma Maiko Ikenouchi Takuji Akamatsu Takeshi Seta Shunji Urai Yoshito Uenoyama Yukitaka Yamashita | 2016 | World Journal of Gastroenterology2016，22，12： | 0 |
| 4 | Stage at diagnosis of colorectal cancer through diagnostic route:Who should be screened?显示文摘BACKGROUND Colorectal cancer(CRC)is a global health concern,with advanced-stage diagnoses contributing to poor prognoses.The efficacy of CRC screening has been well-established;nevertheless,a significant proportion of patients remain unscreened,with>70%of cases diagnosed outside screening.Although identifying specific subgroups for whom CRC screening should be particularly recommended is crucial owing to limited resources,the association between the diagnostic routes and identification of these subgroups has been less appreciated.In the Japanese cancer registry,the diagnostic routes for groups discovered outside of screening are primarily categorized into those with comorbidities found during hospital visits and those with CRC-related symptoms.AIM To clarify the stage at CRC diagnosis based on diagnostic routes.METHODS We conducted a retrospective observational study using a cancer registry of patients with CRC between January 2016 and December 2019 at two hospitals.The diagnostic routes were primarily classified into three groups:Cancer screening,follow-up,and symptomatic.The early-stage was defined as Stages 0 or I.Multivariate and univariate logistic regressions were exploited to determine the odds of early-stage diagnosis in the symptomatic and cancer screening groups,referencing the follow-up group.The adjusted covariates were age,sex,and tumor location.RESULTS Of the 2083 patients,715(34.4%),1064(51.1%),and 304(14.6%)belonged to the follow-up,symptomatic,and cancer screening groups,respectively.Among the 2083 patients,CRCs diagnosed at an early stage were 57.3%(410 of 715),23.9%(254 of 1064),and 59.5%(181 of 304)in the follow-up,symptomatic,and cancer screening groups,respectively.The symptomatic group exhibited a lower likelihood of early-stage diagnosis than the follow-up group[P<0.001,adjusted odds ratio(aOR),0.23;95%confidence interval(95%CI):0.19-0.29].The likelihood of diagnosis at an early stage was similar between the follow-up and cancer screening groups(P=0.493,aOR for early-stage diagnosis in the cancer screening group vs follow-up group=1.11;95%CI=0.82-1.49).CONCLUSION CRCs detected during hospital visits for comorbidities were diagnosed earlier,similar to cancer screening.CRC screening should be recommended,particularly for patients without periodical hospital visits for comorbidities. | Nobukazu Agatsuma Takahiro Utsumi Yoshitaka Nishikawa Takahiro Horimatsu Takeshi Seta Yukitaka Yamashita Yukari Tanaka Takahiro Inoue Yuki Nakanishi Takahiro Shimizu Mikako Ohno Akane Fukushima Takeo Nakayama Hiroshi Seno | 2024 | World Journal of Gastroenterology2024，30，10： | 0 |
| 5 | Mucocele of the appendix due to endometriosis:A rare case report显示文摘Mucocele of the appendix due to endometriosis is extremely rare,and there are only 10 previously reported cases in the English literature.We report a case of mucocele of the appendix due to endometriosis and provide the first review of the literature.A 43-year-old woman was admitted to the hospital because of recurrent right lower abdominal pain during her menstrual periods.Colonoscopy revealed submucosal tumorlike elevations of the appendiceal orifice.Computed tomography and magnetic resonance imaging of the abdomen suggested cystic lesions near the appendix.Consequently,mucocele of the appendix was suspected preoperatively.An open ileocecal resection was performed.Multiple cystic lesions were observed around the appendix.The cystic lesions contained mucus.Histopathological examination was consistent with a mucocele of the appendix due to endometriosis.The postoperative course was uneventful.We present the first review of the literature to clarify the clinical features. | Motoyuki Tsuda Yukitaka Yamashita Shunjiro Azuma Takuji Akamatsu Takeshi Seta Shunji Urai Yoshito Uenoyama Yasunori Deguchi Kazuo Ono Tsutomu Chiba | 2013 | World Journal of Gastroenterology2013，19，30： | 0 |
