Keep Them on the Table: Outcomes Are Improved After Minimally Invasive Colectomy Despite Longer Operative Times in...

Area of Science:

• Colorectal Surgery
• Surgical Oncology
• Patient Outcomes Research

Background:

• Traditional surgical dogma favors short open operations for high-risk patients to minimize anesthesia time.
• This approach contrasts with longer, minimally invasive surgery (MIS) techniques.

Purpose of the Study:

• To compare postoperative outcomes between elective longer MIS and shorter open colectomies in high-risk colon cancer patients.
• To evaluate the impact of operative time and surgical approach on patient recovery.

Main Methods:

• Retrospective comparative cohort study using the National Surgical Quality Improvement Program database (2012-2017).
• Identified patients with American Society of Anesthesiologists (ASA) class 3-4 undergoing right or sigmoid colectomy.
• Compared 30-day postoperative outcomes between short open and long MIS groups.

Main Results:

• Longer MIS right colectomy (n=3775) showed significantly lower rates of morbidity, severe adverse events, mortality, surgical site infections, and wound disruptions compared to short open colectomy.
• Longer MIS sigmoid colectomy (n=1042) also demonstrated decreased overall morbidity, severe adverse events, and shorter length of stay than short open colectomy.
• Patients undergoing longer MIS procedures experienced better outcomes, including discharge to a higher level of care and shorter hospital stays.

Conclusions:

• Longer minimally invasive surgery approaches are associated with superior postoperative outcomes in high-risk patients undergoing colectomy for colon cancer compared to shorter open operations.
• Surgical focus should shift from minimizing operative time to optimizing patient safety and recovery through longer, safer MIS procedures.
• These findings challenge traditional surgical dogma for high-risk patient management.
