BACKGROUND: The aim of this study was to determine the effects of laparoscopic surgery within an ERAS program on outcomes and immunological function in patients with a carcinoma in the right colon.
MATERIAL AND METHODS: Patient data were acquired from a prospectively maintained database, and 176 patients diagnosed with right colon carcinoma with surgery were selected from the database. These patients were divided into a laparoscopic group (Lap group, n=86) and an open operation group (Open group, n=90). All patients received treatment according to a standardized ERAS protocol. We collected data on CRP levels, CD4+/CD8+ ratios, and Treg values in peripheral blood, baseline and surgical characteristics, postoperative complications, and postoperative ileus (POI).
RESULTS: Circulating CD4+/CD8+ ratios and Treg values were decreased and CRP levels were increased in both groups after the operation. However, the values in the Lap group patients recovered much more quickly than those of patients in the Open group (P<0.05). Patients undergoing laparoscopic surgery had significantly less preoperative bleeding (P<0.01), reduced ratio of overall POI (mainly early ileus), and shorter postoperative hospital stay (P=0.03). Multivariate logistic regression analysis showed that POD1 Treg value was an independent predicator for postoperative ileus in patients with right colon carcinoma resection.
CONCLUSIONS: In patients with a carcinoma in the right colon, laparoscopic surgery within an ERAS protocol leads to better immunity preservation after surgery, and POD1 Treg value may be an independent predicator for postoperative ileus, which could, at least in part, explain the shorter hospital stay after surgery.
