Small bowel tumors (SBTs) are difficult to diagnose because of limited opportunities and technical difficulties in evaluating the small bowel. Asymptomatic conditions or nonspecific symptoms make SBT diagnosis more challenging. In Asia, SBTs are reported to be more frequently malignant lymphoma (ML), adenocarcinoma, and gastrointestinal stromal tumor (GIST). In this study, we examined 66 patients diagnosed with SBTs and determined their clinical characteristics.
This retrospective study was conducted from January 2013 to July 2020 at Kurume University Hospital. The modalities used to detect SBTs were computed tomography (CT), positron emission tomography, magnetic resonance imaging, and ultrasonography. Endoscopy was also performed in some cases to confirm SBT diagnosis. The study included 66 patients. The medical data collected included presenting symptoms, tumor location, underlying condition, diagnostic modalities, pathologic diagnosis, and treatment.
ML and adenocarcinoma were the most common tumors (22.7%), followed by GIST (21.2%) and metastatic SBT (18.2%). Symptoms that led to SBT detection were abdominal pain (44.5%), asymptomatic conditions (28.8%), hematochezia (12.1%), and anemia (10.6%). CT was the most used modality to detect SBTs. Nineteen patients were asymptomatic, and SBTs were incidentally detected in them. GISTs and benign tumors were more often asymptomatic than other malignant tumors.
Abdominal pain was the main symptom for SBTs in particular adenocarcinoma, ML, and metastatic SBT. In addition, GIST, which was highly prevalent in Asia, had fewer symptoms. An understanding of these characteristics may be helpful in the clinical practice of SBTs.
小肠肿瘤（SBT）由于评估小肠的机会有限且技术困难，因此难以诊断。无症状或非特异性症状使 SBT 诊断更加困难。在亚洲，SBT 更常报告为恶性淋巴瘤（ML）、腺癌和胃肠道间质瘤（GIST）。在本研究中，我们检查了 66 例诊断为 SBT 的患者，并确定了他们的临床特征。
这项回顾性研究于 2013 年 1 月至 2020 年 7 月在久留米大学医院进行。用于检测 SBT 的方法包括计算机断层扫描（CT）、正电子发射断层扫描、磁共振成像和超声检查。在某些情况下也进行了内镜检查以确认 SBT 诊断。该研究纳入了 66 例患者。收集的医疗数据包括主要症状、肿瘤位置、基础疾病、诊断方式、病理诊断和治疗。
ML 和腺癌是最常见的肿瘤（22.7%），其次是 GIST（21.2%）和转移性 SBT（18.2%）。导致 SBT 检测的症状包括腹痛（44.5%）、无症状（28.8%）、血便（12.1%）和贫血（10.6%）。CT 是检测 SBT 的最常用方式。19 例患者无症状，SBT 是在他们身上偶然发现的。GIST 和良性肿瘤比其他恶性肿瘤更常无症状。
腹痛是 SBT 的主要症状，特别是腺癌、ML 和转移性 SBT。此外，在亚洲高发的 GIST 症状较少。了解这些特征可能有助于 SBT 的临床实践。
