OBJECTIVE: This study aimed to evaluate and compare the short- and long-term outcomes of intracorporeal versus extracorporeal anastomosis techniques in patients who underwent laparoscopic right hemicolectomy for colon cancer.
METHODS: A retrospective analysis was conducted on patients who underwent laparoscopic right colectomy between January 2012 and June 2017 at two different centers. Groups were compared based on demographic data, preoperative clinical features, intraoperative and postoperative variables, pathological findings, and long-term follow-up outcomes.
RESULTS: The study included n=50 patients, with n=24 assigned to the intracorporeal anastomosis group and n=26 to the extracorporeal group. Intraoperative assessment showed that the intracorporeal group had significantly lower estimated blood loss (47±31.1 vs. 92.9±63.8 mL, p=0.01) and shorter total incision length (8.6±5.2 vs. 22.8±13.1 cm, p=0.001). During the early postoperative period, earlier oral intake (2.2±1.4 vs. 4±1.1 days, p=0.001) and shorter hospital stay (5.3±2.1 vs. 7.9±3.2 days, p=0.01) were observed in the intracorporeal group, while ıntensive care unit (ICU) stay was longer (1.1±0.4 vs. 0.3±0.6 days, p=0.001). Pathological evaluation confirmed adequate lymph node dissection (≥12 nodes) in all patients; however, the extracorporeal group demonstrated a higher total lymph node yield (31.9±13.3 vs. 23.3±7.3, p=0.04).
CONCLUSION: Intracorporeal anastomosis in laparoscopic right hemicolectomy may provide certain perioperative benefits, including lower intraoperative blood loss, faster return to oral intake, and reduced hospitalization time. Despite this, the extracorporeal technique yielded a higher number of harvested lymph nodes, although oncological adequacy was achieved in both groups.
