Challenging diagnosis of groove pancreatitis with severe gastric outlet obstruction: A case report.
Article in World journal of clinical cases, 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
backgroundGroove pancreatitis (GP) is a rare focal chronic pancreatitis of the pancreaticoduodenal groove that is usually diagnosed in chronic alcoholics. However, it is often difficult to differentiate from pancreatic or periampullary cancers. In this study, we report a case of GP with the rare symptom of severe gastric outlet obstruction. CASE SUMMARY: A 68-year-old man presented to our institution with severe gastric outlet obstruction accompanied by vomiting persisted for 3 days, severe electrolyte imbalance, and altered mental status with cardiac arrest. Differential diagnosis of cancers of the ampulla of Vater or duodenum was difficult due to discordant findings from preoperative imaging and an endoscopic biopsy of the lesion. In addition, the gastric outlet obstruction did not improve with conservative treatment; therefore, pancreatoduodenectomy was performed. Postoperatively, the histological findings revealed multiple cystic lesions in the duodenal wall that were collectively diagnosed as GP. The patient underwent a follow-up 3 years postoperatively and was found to have no postoperative sequelae.
conclusionIn this case of GP, pancreatoduodenectomy safely treated severe gastric outlet obstruction when a cancer diagnosis could not be excluded.
