Adenocarcinoma arising from heterotopic pancreas at the first portion of the duodenum: a case report.
Review in The Journal of international medical research, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Malignant transformation of a heterotopic pancreas in the duodenum is very rare. To our knowledge, only 15 cases have been reported worldwide, including the present case. We herein report a rare case of malignant transformation of a heterotopic pancreas in the duodenum along with a review of the literature.A 65-year-old man was admitted to our hospital for evaluation of dyspepsia and vomiting. Esophagogastroduodenoscopy showed a stricture of the duodenal bulb. Laparoscopic distal gastrectomy was performed. Although a duodenal tumor had not been suspected, histopathological examination of the surgical specimen showed adenocarcinoma arising from a heterotopic pancreas (Heinrich type III) in the duodenum. Four months postoperatively, the patient received adjuvant chemotherapy. He was still alive without recurrence at 24 months of follow-up.Adenocarcinoma arising in a heterotopic pancreas is rare; therefore, preoperative diagnosis is difficult to obtain. Effective management of a heterotopic pancreas depends on the presence or absence of symptoms. Awareness of the possibility of malignant change in a heterotopic pancreas of the duodenum prior to surgery is helpful for the diagnosis and appropriate management of such patients.
