Influence of preoperative oral carbohydrate loading on the outcome of esophageal cancer surgery: an interrupted time series analysis of the transition from fasting with intravenous infusion to oral intake protocol.

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
objectiveProlonged preoperative fasting has been reported to increase patient discomfort, induce insulin resistance, and lead to complications and delayed recovery. We introduced preoperative oral carbohydrate (CHO) loading, and this study aimed to evaluate the influence on the outcomes of esophageal cancer surgery.
methodsWe evaluated 270 patients who underwent minimally invasive esophagectomy for esophageal cancer. Before implementation, patients fasted after the evening meal on the day before surgery and received glucose-electrolyte infusion. After implementation, patients received oral CHO loading up to three hours before surgery instead of infusion. We evaluated its impact on the incidence of perioperative complications, time to first defecation, length of hospital stay, and postoperative glycemic changes using interrupted time series analysis.
resultsThere were 136 and 134 patients before and after implementation, respectively. No patient experienced aspiration during anesthesia induction. No significant changes were observed in the incidence of postoperative complications (coefficient 6.51, 95% confidence interval - 20.6 to 33.6) or length of stay (coefficient 1.34, 95% confidence interval - 4.75 to 7.42) after the implementation. Meanwhile, a significant reduction in time to first defecation was observed after implementation (coefficient - 0.73, 95% confidence interval - 1.42 to - 0.05). No significant differences in postoperative blood glucose levels were noted.
conclusionsPreoperative oral CHO loading for esophageal cancer surgery can be safely implemented without increasing postoperative complications, blood glucose levels, or length of hospital stay, and is associated with reduction in time to first defecation.
