Risk factors of cervical anastomotic stricture after esophagectomy detected by early postoperative endoscopy.
Article in Surgical endoscopy, 2026. 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
backgroundAnastomotic stricture after esophagectomy with cervical reconstruction remains a clinically significant complication, yet effective preventive strategies are limited. This study aimed to clarify the clinical significance of endoscopic findings on postoperative day 14 for predicting subsequent anastomotic stricture.
methodsThis retrospective single-center cohort study included 106 patients with esophageal cancer who underwent transthoracic esophagectomy with cervical reconstruction between April 2021 and December 2023. Cervical esophagogastric anastomosis was performed using a triangulating stapling technique with a linear stapler. Endoscopy was performed on postoperative day (POD) 14. Anastomotic stricture was defined as luminal narrowing requiring endoscopic balloon dilation within 1 year. Associations between POD 14 endoscopic findings and subsequent stricture were assessed using multivariable analysis. Exploratory analyses evaluated factors associated with ulcer formation.
resultsAnastomotic stricture occurred in 16 patients (15%). Ulcer formation and esophageal edema on POD 14 were independent risk factors for stricture (both P = 0.03). Greater circumferential ulcer extent was significantly associated with higher stricture risk (P = 0.001). Exploratory analyses showed that elevated C-reactive protein on POD 7 (P = 0.004) and an anastomosis located across the thoracic inlet (P = 0.08) were associated with ulcer formation.
conclusionsUlceration observed on POD 14 endoscopy is a significant predictor of subsequent anastomotic stricture after esophagectomy. Early postoperative endoscopic assessment may help identify patients at increased risk of subsequent anastomotic stricture and support risk stratification during postoperative follow-up.
