A case of small intestinal malignant lymphoma associated with intestinal obstruction: A case report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionSmall bowel obstruction (SBO) is a common surgical emergency, most frequently caused by postoperative adhesions. However, neoplastic etiologies, including malignant lymphoma, should also be considered in the differential diagnosis. CASE PRESENTATION: A 78-year-old Japanese man with a history of recurrent SBO since 2021 presented with nausea and abdominal distention. He had previously undergone conservative treatment on seven occasions. Contrast-enhanced computed tomography revealed small bowel dilatation with segmental wall thickening and enhanced contrast effect, along with enlarged mesenteric lymph nodes. He was diagnosed with SBO and admitted for emergency treatment. An ileus tube was inserted, and contrast study on day 3 revealed a stricture in the ileum, which the tube could not pass. Adhesive ileus and small intestinal tumor were both considered. As conservative treatment was ineffective, laparoscopic-assisted segmental ileal resection was performed. Histopathological examination revealed diffuse large B-cell lymphoma. Postoperative recovery was uneventful, and he was discharged on postoperative day 21. Positron emission tomography/computed tomography showed FDG uptake in mesenteric lymph nodes (SUVmax 3.7), consistent with Lugano stage II disease. Due to advanced age and dementia, the patient did not undergo chemotherapy. He remains under surgical follow-up without disease progression one year postoperatively. DISCUSSION: This case highlights that repeated SBO may not always be caused by adhesions alone, and intestinal lymphoma should be considered, especially when imaging reveals suspicious findings.
conclusionsIn cases of recurrent SBO, small intestinal lymphoma should be included in the differential diagnosis, even in elderly patients with a history of abdominal surgery.
