Laparoscopy and laparotomy for patients with transverse colon cancer: comparative analysis of short-term surgical outcomes

Objective: To compare the efficacy of laparoscopy versus laparotomy in the treatment of transverse colon cancer. Methods: Data from 100 patients with transverse colon cancer treated in our hospital from January 2018 to December 2020 were retrospectively analyzed in this study. According to the treatment methods, these patients were assigned into two groups: a laparotomy group (n=50) and a laparoscopy group (n=50). The intraoperative parameters, postoperative recovery, incidences of complications, postoperative pain, quality of life (QoL) score, postoperative serum inflammatory cytokine (hs-CRP, TNF-alpha, and IL-6) levels, and prognostic nutritional index (PNI) were analyzed and compared between the two groups. Results: There was no significant difference in number of resected lymph nodes between the two groups. The operation time and intraoperative bleeding in the laparoscopy group were significantly less than those in the laparotomy group (P<0.05). The hospital stay, duration of gastrointestinal function recovery, and time of first postoperative flatus in the laparoscopy group were significantly shorter than those in the laparotomy group (all P<0.001). Moreover, the incidence of overall complications in the laparoscopy group was significantly lower than that in the laparotomy group (P<0.05). Compared with those in the laparotomy group, the VAS score was obviously lower and the QoL score was significantly higher in the laparoscopy group (all P<0.001). Patients in the laparoscopy group exhibited lower levels of postoperative hs-CRP, TNF-alpha and IL-6 in contrast to those in the laparotomy group (P<0.05). In additional, there was no significant difference in the PNI level before surgery between two groups. After surgery, the PNI level in the laparoscopy group was obviously higher than that in the laparotomy group (P<0.001). Conclusion: Laparoscopy is superior to laparotomy in treatment of transverse colon cancer through achieving better intraoperative outcomes, promoting postoperative recovery, reducing the incidence of complications and inflammatory reactions, alleviating postoperative pain, and improving therapeutic effects.
