85.1) patients in the NJEEN group versus 64.4% (95% CI 54.2-73.6) in TPN group (p = 0.040). NJEEN was associated with higher frequency of postoperative pancreatic fistula (48.1% vs 27.7%, p = 0.012) and higher severity (grade B/C 29.4% vs 13.9%; P = 0.007). There was no significant difference in the incidence of post-pancreatectomy hemorrhage, delayed gastric emptying, infectious complications, the grade of postoperative complications, and the length of postoperative stay. A successful NJEEN was achieved in 63% patients. Conclusion: In patients undergoing PD, NJEEN was associated with an increased overall postoperative complications rate. The frequency and the severity of POPF were also significantly increased after NJEEN. In terms of safety and feasibility, NJEEN should not be recommended.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
