“…Several studies have reported on instrumented anastomosis for colorectal cancer [9,[11][12][13]. The overall complication rate was 25.7% for FEEA and 35.4% for triangular anastomosis [9]. In the present study, complication rates were 17.3% for FEEA and 11.1% for Delta, comparable to previous reports, and both anastomoses were performed safely.…”

Background Several methods are used for reconstruction in colon cancer surgery, including hand-sewn or stapled anastomosis. However, few reports have compared short-term outcomes among reconstruction methods. This study compared short-term outcomes between delta-shaped anastomosis (Delta) and functional end-to-end anastomosis (FEEA). Methods We retrospectively reviewed 1314 consecutive patients who underwent colorectal surgery with FEEA or Delta reconstruction between January 2016 and December 2023. Patients were divided into two groups according to reconstruction by FEEA (F group; n = 1242) or Delta (D group; n = 72). Propensity score matching was applied to minimize the possibility of selection bias and to balance covariates that could affect postoperative complications. Short-term outcomes were compared between groups. Results Postoperative complications occurred in 215 patients (17.3%) in F group and 8 patients (11.1%) in D group. Before matching, transverse colon cancer was more frequent (p = 0.002), clinical N-positive status was less frequent (44.1% vs 16.7%, p < 0.001), distant metastasis was less frequent (11.7% vs 1.4%, p = 0.003), and laparoscopic approach was more frequent (87.8% vs 100%, p < 0.001) in D group. After matching, no differences in any clinical factor were evident between groups. Blood loss was lower (28 mL vs 10 mL, p = 0.002) in D group. However, operation time and postoperative complication rates were similar between groups. Conclusions Delta and FEEA were both considered safe as reconstruction methods. Delta anastomosis may be more useful for patients with transverse colon cancer for whom transfusion should be minimized.

“…The main cause of this result seems to be the difference in the linear stapler type used in intestinal anastomosis. In the MA group, intestinal anastomosis was performed by functional end‐to‐end anastomosis or triangulating anastomosis [26] using a triple‐row linear stapler. In contrast, in the IA group, intestinal anastomosis was performed by functional end‐to‐end anastomosis using a double‐row linear stapler.…”

Aim In laparoscopic colectomy with complete mesocolic excision and D3 lymphadenectomy for right‐sided colon cancer, either an inferior approach (IA) or a medial approach (MA) is selected in our institution based on the surgeon's preference. The present study compared the treatment outcomes between IA and MA. Method This retrospective, single‐centre study using propensity score matching analysed the short‐ and long‐term outcomes of laparoscopic surgery in patients with right‐sided colon cancer from 2010 to 2019 at Cancer Institute Hospital. Results After patient selection, 1011 patients remained for the analysis, of which 67% underwent IA surgery and 33% underwent MA surgery. After propensity score matching (1:1), 325 patients in each group were analysed. Regarding the short‐term outcomes, there were no significant differences in the operation time, rate of conversion to open surgery or postoperative complication rate (Clavien–Dindo Grade ≥ III) between the two groups, although the intra‐operative median blood loss was significantly less in the IA group than in the MA group (IA, 13 ml vs. MA, 20 ml, P < 0.0001). Regarding the long‐term outcomes, the relapse‐free survival, liver‐relapse‐free survival, cancer‐specific survival and overall survival were all similar between groups. Conclusion Both the IA and MA in laparoscopic colectomy with complete mesocolic excision and D3 lymphadenectomy for right‐sided colon cancer are safe and feasible approaches; the IA may have an advantage over the MA in terms of reduced intra‐operative blood loss. Based on their similar oncological outcomes, either the IA or MA can be selected, based on one's preference.
