“…Although there were controversial results concerning the association of the length of resected bowel and the LN yield [1,3,10,11,14,15], some authors also tried to find the cutoff values of specimen lengths for adequate LN counts. They showed that there should be almost < 20 cm of specimen length for sufficient LN counts [22,23].…”

“…Although the length of resected colon is dependent on mucosal margins, arterial anatomic variations, and extent of lymphadenec-tomy, resection of longer colonic segments with larger mesocolic mesentery may also lead to higher counts of LN [10]. An increase in the number of retrieved LNs with increasing length of resected colon segments has been shown [3,8,[11][12][13][14][15][16][17].…”

The minimum harvested 12 lymph nodes (LNs) is regarded as the limit for accurate staging of nodal status in colorectal cancer patients. Besides the association of the lengths of resected intestinal segments and vascular pedicles, the mesocolic mesenteric area's impact on LN count has not been studied. We aimed to evaluate the associations between metric variables, including the mesocolic mesentery area on the nodal harvest. Methods: All consecutive patients who underwent elective colectomy with a curative intention for colon adenocarcinoma were prospectively included. The metric variables included the lengths of resected intestinal segments, vascular pedicle, and colonic mesenteric area. The variables influencing the LN count and the correlation between the total LN count and the specimens' relevant metric measurements were analyzed. Results: There were 46 patients with a median age of 64 years. The median count for total LNs was 22, and the LN positivity was 59.2%. There was an inadequate LN yield ( < 12) in 3 patients (6.1%). No significant associations were found between the adequacy of nodal harvest and the demographic, clinical, and tumoral features (P > 0.05). There were significant positive correlations between total LN number and length of vascular pedicle and mesenteric area (r = 0.576, P < 0.001 and r = 0.566, P < 0.001). Conclusion: The length of the vascular pedicle and mesenteric area were significantly correlated with total LN counts. Although there was no significant impact on the length of resected segments, the colonic mesenteric area can be used alone as a measure for the assessment of the nodal yield in colon cancer.

“…It is beneficial to ensure the precision of anatomical separation, obtain sufficient tumor incisional margin and reduce trauma, which promote body function and recovery time shortening. However, laparoscopic surgery has high requirements for the operator’s skills, and the uterus, small intestine and other adjacent organs during the operation will affect the operation, which prolongs the operation time to a certain extent[ 17 , 18 ].…”

BACKGROUND Colon cancer is associated with a higher incidence among residents in high-altitude areas. Hypoxic environment at high altitudes inhibits the phagocytic and oxygen-dependent killing function of phagocytes, thereby increasing the inflammatory factors, inhibiting the body’s innate immunity and increasing the risk of colon cancer. AIM To examine the effect of minimally invasive surgery vs laparotomy in patients with colon cancer residing in high-altitude areas. METHODS Ninety-two patients with colon cancer in our hospital from January 2019 to February 2021 were selected and divided into the minimally invasive surgery and laparotomy groups using the random number table method, with 46 patients in each group. Minimally invasive surgery was performed in the minimally invasive group and laparotomy in the laparotomy group. Operative conditions, inflammatory index pre- and post-surgery, immune function index and complication probability were measured. RESULTS Operative duration was significantly longer and intraoperative blood loss and recovery time of gastrointestinal function were significantly less (all P < 0.05) in the minimally invasive group than in the laparotomy group. The number of lymph nodes dissected was not significantly different. Before surgery, there were no significant differences in serum C-reactive protein, interleukin-6 and tumor necrosis factor-α levels between the groups, whereas after surgery, the levels were significantly higher in the minimally invasive group (26.98 ± 6.91 mg/L, 146.38 ± 11.23 ng/mL and 83.51 ± 8.69 pg/mL vs 41.15 ± 8.39 mg/L, 186.79 ± 15.36 ng/mL and 110.65 ± 12.84 pg/mL, respectively, P < 0.05). Furthermore, before surgery, there were no significant differences in CD3+, CD4+ and CD4+/CD8+ levels between the groups, whereas after surgery, the levels decreased in both groups, being significantly higher in the minimally invasive group (55.61% ± 4.39%, 35.45% ± 3.67% and 1.30 ± 0.35 vs 49.68% ± 5.33%, 31.21% ± 3.25% and 1.13 ± 0.30, respectively, P < 0.05). Complication probability was significantly lower in the minimally invasive group (4.35% vs 17.39%, P < 0.05). CONCLUSION Laparoscopic minimally invasive procedures reduce surgical trauma and alleviate the inflammatory response and immune dysfunction caused by invasive operation. It also shortens recovery time and reduces complication probability.
