Several important questions are raised by Jung and colleagues¹ in their article in this issue of JAMA Surgery. The first question is whether retrospective video review can be used to identify technical risk factors associated with the construction of a gastrojejunostomy that might contribute to the development of delayed gastric emptying after pancreatoduodenectomy. Despite the challenges of standardization of technique and the limitations of retrospective analysis, the authors have identified the following 3 technical risk factors for delayed gastric emptying: a gastrojejunostomy flow angle of greater than 30°, a shorter gastrotomy, and a sutured anastomosis.

Jung和其同事¹在本期JAMA Surgery中的文章中提出了几个重要问题。第一个问题是回顾性视频审查是否可用于确定与胃空肠造口术相关的技术风险因素，这些因素可能会导致胰十二指肠切除术后胃排空延迟。尽管存在技术标准化的挑战和回顾性分析的局限性，但作者已经确定了以下3个导致胃排空延迟的技术风险因素：胃空肠造口术的流动角度大于30°，较短的胃切开术以及缝合的吻合术。
