Purpose
Traditionally, fasting from midnight has been a standard practice in elective surgery for reduce the risk of aspiration. However, Enhanced Recovery After Surgery (ERAS) programs recommend clear fluid intake until 2 hours before anesthesia. This study aimed to evaluate the safety and patient satisfaction of preoperative carbohydrate drink intake until 2 hours before colorectal cancer surgery.
Methods
Sixty patients who underwent colorectal cancer surgery between April 2021 and February 2023 at Keimyung University Dongsan Medical Center were enrolled. This study included 30 patients who fasted from midnight (nothing by mouth [NPO] group) and 30 patients who consumed a high concentration of complex carbohydrate fluids (New Care NO-NPO) until 2 hours before surgery (No-NPO group). Patient satisfaction was assessed using a visual analog scale. Perioperative and postoperative outcomes were compared.
Results
Basic characteristics of patients were similar for the 2 groups. The No-NPO group had a significantly higher patient satisfaction score than the NPO group (3.7 vs. 2.2, P=0.040). Scores of operative difficulty, operation time, blood loss, postoperative recovery parameters, and postoperative complication rates were similar for the 2 groups. Pathological outcomes were also comparable. No mortality occurred in either group.
Conclusion
High-concentration carbohydrate fluid intake until 2 hours before induction of anesthesia could improve patient satisfaction without increasing postoperative complications, demonstrating its safety and feasibility in colorectal cancer surgery. Trial registration CRIS (cris.nih.go.kr) identifier: KCT0011323.

Purpose
This study aimed to compare the wound cosmesis of a single-incision approach on scar assessment after laparoscopic surgery for colon cancer.
Methods
This study included 32 patients undergoing single-port laparoscopic surgery (SPLS) and 61 patients undergoing multiport laparoscopic surgery (MPLS) for colon cancer at 3 tertiary referral hospitals between September 2011 and December 2019. We modified and applied the Korean version of the Patient and Observer Scar Assessment Scale (POSAS) to assess cosmetic outcomes. To assess the interobserver reliability using intraclass correlation coefficient values for the Observer Scar Assessment Scale (OSAS), the surgeons evaluated 5 images of postoperative scars.
Results
No significant differences were observed in the time before the return of normal bowel function, time to sips of water and soft diet initiation, length of in-hospital stay, and postoperative complication rate. The SPLS group had a shorter total incision length than the MPLS group. The POSAS favored the SPLS approach, revealing significant differences in the Patient Scar Assessment Scale (PSAS), OSAS, and overall scores. The SPLS approach was an independent factor influencing the POSAS, PSAS, and OSAS scores. Eleven colorectal surgeons had a significantly substantial intraclass coefficient.
Conclusion
The cosmetic outcomes of SPLS as assessed by the patients and surgeons were superior to those of MPLS in colon cancer. Reducing the number of ports is an independent factor affecting scar assessment by patients and observers.
