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
introductionPancreatoduodenectomy after esophagectomy with an ileocolonic interposition is technically challenging because perfusion of both the remnant stomach and the interposed ileocolonic conduit must be preserved. Although pancreatic head resection after proximal gastrectomy or gastric conduit reconstruction has been reported, pylorus-preserving pancreatoduodenectomy (PPPD) after an ileocolonic interposition has not been previously reported. We report a case of PPPD after an ileocolonic interposition in which both the right gastroepiploic vessels and the middle colic arterial arcade were preserved, and intraoperative indocyanine green (ICG) fluorescence imaging was used to confirm adequate perfusion. CASE PRESENTATION: A 78-year-old man presented at our hospital with fatigue. Contrast-enhanced CT revealed a localized ampullary tumor with upstream dilatation of the common bile duct and main pancreatic duct, without distant metastases or significant lymphadenopathy. Eight years earlier, he had undergone thoracoabdominal esophagectomy with 3-field lymph node dissection and retrosternal ileocolonic interposition for esophageal squamous cell carcinoma in our hospital. In that setting, perfusion of the remnant stomach depended on the right gastroepiploic vascular territory, whereas the interposed ileocolonic conduit was supplied by the middle colic arterial arcade. Therefore, PPPD was planned with preservation of both vascular territories. Careful dissection enabled preservation of the gastroduodenal artery, right gastroepiploic vessels, and the mesentery carrying the middle colic vessels. Intraoperative ICG fluorescence imaging confirmed adequate perfusion of both the remnant stomach and the ileocolonic conduit. The postoperative course was uneventful, and the patient was discharged on POD 14. Histopathological examination revealed an ampullary adenocarcinoma (pT2N0M0, stage IB). The patient remained alive without recurrence 18 months after surgery.
conclusionsThis case demonstrates that PPPD after esophagectomy with an ileocolonic interposition is feasible in select patients. Preservation of both the right gastroepiploic vessels and the middle colic arterial arcade is essential to maintain perfusion of the remnant stomach and the ileocolonic conduit. Intraoperative ICG fluorescence imaging is useful for the real-time confirmation of perfusion in both vascular territories.
