Gastroduodenal intussusception caused by gastric gastrointestinal stromal tumor in adults: a case report and literature review

Intussusception mostly occurs in childhood and is rare in adults. Although intussusception can occur in any part of the gastrointestinal tract, gastroduodenal intussusception caused by a gastric tumor is relatively uncommon in clinical practice. A PubMed search identified 24 published cases of gastroduodenal intussusception caused by gastric gastrointestinal stromal tumor (GIST); however, it is possible that we missed other cases not included in PubMed. Here we report a case of gastroduodenal intussusception caused by gastric GIST in an 85-year-old man. He came to the hospital because of recurrent black stools. Plain computed tomography (CT) scan indicated a mass in the gastric antrum, with slight enhancement in the arterial phase on enhanced CT scan. He was diagnosed with GIST. In addition, images indicated that the mass overlapped into the duodenum, and gastroduodenal intussusception was thus considered. Gastroscopy showed a huge mass in the gastric body. According to the gastroscopy and CT results, gastroduodenal intussusception caused by a gastric tumor was considered. The patient underwent complete surgical removal, which revealed a mass originating from the gastric antrum and overlapping into the duodenum. The postoperative pathological diagnosis was intermediate-risk gastric GIST. The patient was followed up for 4 months without tumor recurrence.

多参数MRI联合临床危险因素术前预测直肠癌淋巴血管间隙侵犯的应用价值

目的 探讨多参数 MRI 联合临床危险因素术前预测直肠癌淋巴血管间隙侵犯（LSVI）的价值。 方法 回顾性分析池州市人民医院 2022 年 4 月至 2023 年 11 月经术后病理证实的 38 例直肠癌患者的临床及影像学资料,所有患者均行常规 MRI、合成 MRI及 IVIM-DWI 序列扫描。依据术后病理结果分为 LVSI 阳性组（n=14）和 LVSI 阴性组（n=24）。采用单因素和多因素 logistic 回归分析LVSI 阳性组和 LVSI 阴性组的临床资料,分析 LVSI 的临床危险因素;比较两组患者合成 MRI （T1 值、T₂ 值、PD 值）及 IVIM-DWI 参数（D值、D*值、f 值）,采用受试者工作特征（ROC）曲线评价各定量参数预测模型及联合临床危险因素预测模型的诊断效能。 结果 合成MRI 的 T₂ 值及 IVIM-DWI 的 D 值、f 值在直肠癌 LVSI 阳性组和阴性组中比较差异具有统计学意义（P＜0.05）。术前 CEA（OR=10.818,95%CI：1.391~84.124）及临床 N 分期（OR=11.852,95%CI：1.534~91.552）是直肠癌 LVSI 的独立危险因素（P＜0.05）。单独的 T₂ 值、D 值、f 值及三者联合的曲线下面积（AUC）分别为 0.801、0.747、0.766、0.807,联合临床危险因素的预测模型效能最高（AUC=0.845）,灵敏度为 78.58%,特异度为 100%。 结论 多参数 MRI 术前可有效预测直肠癌 LVSI 的状态,结合临床危险因素的联合预测模型可进一步提升预测效能,有助于临床医师制定个性化直肠癌治疗方案。     

Causal role of the right temporoparietal junction in selfishness depends on the social partner

The right temporoparietal junction (rTPJ) is a hub of the mentalizing network, but its causal role in social decisions remains an area of active investigation. While prior studies using causal neurostimulation methods have confirmed the role of the rTPJ in mentalizing and strategic social interactions, most of the evidence for its role in resource-sharing decisions comes from correlational neuroimaging studies. Further, it remains unclear if the influence of the rTPJ on decisions about sharing resources depends on whether the other person is salient and identifiable. To clarify the causal role of the rTPJ in social decision making, we examined the effects of putatively inhibitory rTPJ transcranial magnetic stimulation (TMS) on Dictator Game behavior with one partner that was physically present and one that was only minimally identified. Under control conditions, participants tended to create more advantageous inequity toward the partner that was only minimally identified, selfishly keeping more resources themselves. rTPJ TMS reduced this differential treatment of the two partners. Clarifying prior mixed findings, results suggest that the rTPJ may play a role in differentiating between others when deciding how equitably to divide resources, but may not play a general role in reducing selfishness by promoting aversion to advantageous inequity.
