BMC Cancer (2025) 25:1035  \n[https://doi.org/10.1186/s12885-025-14437-w](https://doi.org/10.1186/s12885-025-14437-w)  \nBMC Cancer  \n RESEARCH Open Access  \nComparison of double-layered  \nscallop-shaped anastomosis and circular  \nstapled anastomosis in Ivor–Lewis surgery for esophageal and EGJ cancer: a retrospective cohort study  \nKunKun Li1, QianYang1, YingJian Wang1, TaiMing Zhang1, Liang Zhang1, Liang Chen1, Tao Bao 1 and Wei Guo1*  \nAbstract  \nBackground Cancers ofthe lower esophagus and esophagogastric junction (EGJ) are highly aggressive and have poor prognoses. Minimally invasive Ivor–Lewis surgery (MIIL) is the preferred treatment, but anastomotic leakage (AL) remains a critical complication of this procedure. In the present study, we introduce a novel double-layered scallopshaped anastomosis (DLSSA) technique and compare its outcomes with those of circular stapled esophagogastric anastomosis (CSEA) .  \nMethods From April 2016 to February 2023, 117 patients with distal esophageal or EGJ cancer who underwent complete thoracoscopic–laparoscopic Ivor–Lewis surgery were retrospectively analyzed. Patients were divided into DLSSA (n= 50) and CSEA (n= 67) groups. The median value and ranges are used to present the numerical data. Continuous and categorical variables were compared between groups with the Kruskal‒Wallis test and Fisher’s exact test or χ2 test, respectively. Multivariable binary logistic regression analyses were performed to identify potential prognostic factors.  \nResults The median total operation duration was similar between the groups (280 min) . Intraoperative blood loss was slightly greater in the CSEA group (120 ml vs. 100 ml, p = 0 . 001) . Postoperative complications occurred in 32. 5% of the patients, with no significant between-group difference. However, the incidence of AL was significantly lower (4 . 0% vs. 17. 9%, p = 0 . 022) and that of pleural effusion was significantly greater (10 . 0% vs. 1. 5%, p = 0 . 039) in the DLSSA group than in the CSEA group. Multivariable analysis revealed that a higher body mass index (OR = 1 .453, 95% CI: 1.119–1. 888; p = 0 . 005) was a risk factor for AL, whereas undergoing DLSSA was associated with reduced AL risk  \n(OR = 0 . 052, 95% CI: 0 .005–0. 525; p = 0 . 012), and both variables were considered independent predictors of AL risk. Conclusion Compared with CSEA, DLSSA was associated with significantly lower risk of AL in thoracoscopic Ivor– Lewis surgery, demonstrating its potential as a safer anastomotic technique. However, its association with increased pleural effusion warrants further investigation. Prospective randomized trials are needed to validate long-term outcomes and optimize procedural efficacy.  \n*Correspondence: Wei Guo [gyguowei@hotmail.com](gyguowei@hotmail.com)  \n© The Author(s) 2025.
