ABSTRACT
Background:
Minimally invasive surgery has been demonstrated to have clear advantages in colon cancer management, with a decrease in the morbidity and mortality associated with surgery. With the introduction of intracorporeal anastomosis (ICA), the entire mesenteric dissection and division is performed under vision laparoscopically and may lead to superior lymph node harvest. The aim of our study is to evaluate lymph node harvest in patients undergoing totally laparoscopic right hemicolectomy with ICA compared to laparoscopic-assisted right hemicolectomy with extracorporeal anastomosis (ECA).Methods:
This is a single institution retrospective cohort study. Eligible patients underwent laparoscopic right hemicolectomy at our institution between 2012 and 2022. Patients were identified using a hospital database, and surgeon office databases. Patients included underwent laparoscopic right hemicolectomy for neoplastic lesions (colon cancer/unresectable polyps), or benign etiologies. We excluded patients who underwent laparotomy (intra-operative conversion), resection without anastomosis, resection for IBD, or lack of documented lymph node number. Data were compared using two-sided t-test evaluation with a 95% confidence interval.Results:
A total of 679 patients were included, 493 ECA (72.6%) and 186 ICA (27.4%). Patient demographics (age, biologic sex, American Society of Anesthesiologists and body mass index) were not significantly different. Lymph node harvest was significantly higher in those with ICA (24 ± 14 versus 21 ± 1, P < .05). In subgroup analysis, this difference was maintained in patients with malignant processes (27 ± 14 versus 23 ± 10, P < .05).Conclusions:
In our experience, ICA has higher lymph node harvest in comparison to ECA. This may improve outcomes and options for adjuvant therapies in malignant indications.Palavras-chave
