Comparison of the effects of an ERAS program and a single-port laparoscopic surgery on postoperative outcomes of colon cancer patients

Advancement of the surgical modality and perioperative care are the two main dimensions for the modern improvement of surgical outcome. The purpose of this study was to compare the effectiveness of the two by using the data from the single-port laparoscopic surgery and the early recovery after surgery (ERAS) program. Patients who underwent elective surgery for primary adenocarcinoma of the colon were divided into three groups and compared: ERAS (multi-port laparoscopic surgery with ERAS perioperative care), Conventional-SILS (single-port surgery with conventional perioperative care), or Conventional-Multi (multi-port laparoscopic surgery with conventional perioperative care). Ninety-one, 83, and 96 patients were registered, respectively. There were no differences among the three groups in baseline characteristics except pathological stage and operation site in colon. Although the ERAS group started a soft diet earlier and had earlier discharge, there were no differences in intra- and post-operative morbidity rate, readmission rate, or reoperation rate. The ERAS perioperative care was a significant factor for reducing length of hospital stay in the multivariate analysis, while single-port surgery was not. In modern laparoscopic colon cancer treatment, a systemic approach such as the ERAS program appears to be more effective than a technical approach for significantly improving short-term surgical outcomes.
