How long should a patient stay in the hospital after surgery for rectal cancer?

The length of hospital stay after surgery for rectal cancer varies and there is no uniform standard, typically ranging from 7 to 14 days. The key factors include the surgical approach, the patient's recovery progress, and the presence of complications. Minimally invasive procedures cause less trauma and allow faster recovery, resulting in shorter hospital stays; in contrast, patients undergoing traditional open abdominal surgery or experiencing postoperative complications generally require a longer hospitalization. Detailed analysis is as follows:

For minimally invasive surgeries such as laparoscopic or robot-assisted procedures, gastrointestinal function usually recovers quickly. Patients can typically get out of bed within 1–2 days after surgery and start consuming liquid diets by day 3–4. If no complications such as infection or bleeding occur, discharge may be possible within 7 to 10 days. These techniques involve less physical trauma and milder postoperative pain, facilitating rapid recovery.

Due to larger incisions and slower recovery, traditional open abdominal surgery usually requires a hospital stay of 10 to 14 days. If complications such as anastomotic leakage or bowel obstruction occur, additional treatment and observation are needed, further extending the hospitalization period.

Prior to discharge, it is essential to ensure proper wound healing and gradual restoration of bowel function. After returning home, patients should continue following medical advice regarding dietary adjustments, wound care, and regular follow-up visits.
