“…Anastomotic leakage can give rise to a range of associated infectious complications, including abdominal infection, pelvic abscess, diffuse peritonitis, and sepsis, leading to prolonged hospitalization, reoperation, and even patient fatalities [8]. With advancement in surgeons' understanding of anatomy and re nement of surgical techniques, preservation of the left colic artery (LCA) has been observed to signi cantly mitigate the occurrence of AL following surgery [9,10]. However, this approach is technically demanding and time-consuming, especially for the less experienced surgeon.…”

Background Preservation of the left colic artery (LCA) reduces the incidence of anastomotic leakage (AL) in radical resection of rectal cancer (RC). However, anatomical variations in the branches of the inferior mesenteric artery (IMA) and LCA present significant surgical challenges. Here, we construct a 3D-printed IMA model to precisely determine the location and course of the LCA before surgery, and investigate the beneficial impact of this model on surgery performance. Methods We retrospectively reviewed patients with RC who received laparoscopic radical resection between January 2022 and November 2023 at Fuyang People's Hospital. Patients were divided into 3D printing group (cohort A) and control group (cohort B) and their perioperative characteristics were statistically analyzed. Results Cohort A comprised 44 patients, while cohort B consisted of 57 patients. Operating time (200.340 ± 44.254 vs. 237.018 ± 71.006 min, p = 0.004), intraoperative blood loss (37.500 ± 14.480 vs. 63.333 ± 25.843 ml, p = 0.001), duration of hospitalization (14.022 ± 2.398 vs. 18.263 ± 9.328 days, p = 0.004), and postoperative recovery time (8.841 ± 2.088 vs. 11.461 ± 6.602 days, p = 0.014) were significantly lower in cohort A than in cohort B. There were no significant differences in the number of lymph node dissections, presence of lymph vessel invasion, and AL between the two groups. Conclusions Utilization of a 3D-printed IMA model in laparoscopic radical resection of RC can assist the surgeon in understanding the LCA anatomy preoperatively, reducing intraoperative bleeding, shortening operating time, and promoting rapid postoperative recovery.

Background Previous studies have shown that preserving the left colic artery (LCA) during laparoscopic radical resection for rectal cancer (RC) can maintain the blood supply to the remaining colon without compromising the oncological outcomes. However, anatomical variations in the branches of the inferior mesenteric artery (IMA) and LCA present significant surgical challenges. Here, we construct a 3D printing IMA model for preoperative rehearsal and intraoperative navigation to analyze its positive impact on surgical safety. Methods We retrospectively collected clinical dates from patients with RC who received laparoscopic radical resection from January 2022 to May 2024 at Fuyang City People's Hospital. Patients were divided into 3D printing group and control group and their perioperative characteristics were statistically analyzed. Results 172 patients who underwent laparoscopic radical resection for RC were included in the study. Among them, a total of 32 patients were excluded due to exclusion criteria. Finally, observe group (3D printing group) was comprised of 72 patients, while control group consisted of 68 patients. Operating time (196.7 ± 44.5 vs. 233.3 ± 44.3 min, p < 0.001), intraoperative blood loss (43.9 ± 31.3 vs. 58.2 ± 30.8 ml, p = 0.005), duration of hospitalization (14.3 ± 5.1 vs. 18.7 ± 9.2 days, p < 0.001), and postoperative recovery time (9.1 ± 5.1 vs. 11.9 ± 7.1 days, p = 0.007) were significantly lower in observe group than in control group. There were no significant differences in the number of lymph node dissections, presence of lymph vessel invasion, postoperative intestinal obstruction and anastomotic leakage between the two groups. Conclusions Utilization of a 3D-printed IMA model in laparoscopic radical resection of RC can assist the surgeon in understanding the LCA anatomy preoperatively, reducing intraoperative bleeding, shortening operating time.
