Mesenteric Mass Causing Bowel Obstruction in Waldenström Macroglobulinemia.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Waldenström macroglobulinemia (WM) is a rare, indolent lymphoplasmacytic lymphoma characterized by bone marrow infiltration and monoclonal immunoglobulin M (IgM) production. While WM is usually characterized by slow clinical progression, the occurrence of abdominal masses leading to intestinal obstruction is an exceptional manifestation. We report the case of a 62-year-old man referred for evaluation of a pulmonary lesion, with positron emission tomography-computed tomography (PET-CT) findings suggestive of a systemic lymphoproliferative process involving the abdomen and mesentery. Bone marrow immunophenotyping confirmed WM, and histological examination of an abdominal mass revealed a low-grade B-cell non-Hodgkin lymphoma. Initial treatment with bendamustine and rituximab was started. However, the patient developed recurrent abdominal cramps, weight loss, and progressive signs of bowel obstruction, culminating in a laparoscopic segmental enterectomy. Histopathology of the resected specimen demonstrated transmural intestinal ischemia and fibrosis, but no residual lymphoma. Postoperatively, the patient had an uneventful recovery with resolution of symptoms. This case highlights a rare and severe gastrointestinal complication of WM requiring surgical intervention despite early chemotherapy. It emphasizes the importance of a multidisciplinary approach when managing atypical presentations of hematologic malignancies.
