Splenic Torsion in a Patient with Polysplenia Syndrome and Dorsal Pancreatic Agenesis: A Case Report.
Article in Surgical case reports, 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
introductionPartial splenic torsion in polysplenia syndrome is an extremely rare condition. We encountered and performed surgery for a case of partial splenic torsion in a patient with polysplenia syndrome coexisting with agenesis of the dorsal pancreas. CASE PRESENTATION: A 30-year-old woman with heterotaxy syndrome presented with intermittent epigastric and right lateral abdominal pain persisting for 2 weeks. She was referred to our hospital. Abdominal contrast-enhanced CT revealed multiple spleens on the right side, a right-sided stomach, and agenesis of the dorsal pancreas. One of the 5 spleens showed no contrast enhancement. Suspecting torsion or infarction, we opted for surgical intervention. Intraoperative findings revealed a small spleen with poor coloration and 180-degree torsion, which we removed. Additionally, we identified another poorly anchored spleen and performed splenopexy to secure this wandering spleen.
conclusionsPolysplenia syndrome is a rare condition involving multiple spleens in the setting of heterotaxy syndrome-a defect in the left-right axis of the thoracic or abdominal organs without a complete mirror image. Several reports have described polysplenia syndrome coexisting with agenesis of the dorsal pancreas. Including our case, 11 instances of splenic torsion associated with polysplenia syndrome have been reported in English, with the current patient being the oldest. Furthermore, this is the 1st reported case of splenic torsion occurring in the context of polysplenia syndrome with agenesis of the dorsal pancreas. Our patient had 2 notable anatomical characteristics: first, a vascular variation in which the right celiac artery lacked a common hepatic artery and instead formed a common trunk with the superior mesenteric artery and common hepatic artery, resembling Adachi type VI (group 24); and second, a centrally located, unfixed dorsal spleen that underwent torsion. We hypothesize that splenic torsion occurred due to the central spleen's mobility and its slightly elongated splenic artery.
