Introduction:
Laparoscopic distal gastrectomy (LDG) is the standard treatment for gastric cancer, during which the laparoscopic Billroth I anastomosis technique, also known as the delta-shaped anastomosis (DA), is widely performed. This study aimed to evaluate the differences in short- and long-term symptoms between DA and traditional circular anastomosis (CA) techniques.
Methods:
We retrospectively compared DA and CA procedures in patients undergoing LDG and subsequent reconstruction using the Billroth I method at the Kanagawa Cancer Center from 2017 to 2022.
Results:
Other than blood loss, no significant differences were observed in the short-term outcomes between the two groups. However, 1-year post-surgery, the DA group had a higher incidence of diarrhea, lower incidence of remnant gastritis, and higher weight loss than the CA group.
Conclusion:
Both DA and CA techniques were similar in terms of safety. However, the DA group had a higher incidence of diarrhea and a lower incidence of remnant gastritis than the CA group 1-year after surgery.
