Summary
Laparoscopic colorectal surgery shows comparable morbidity and mortality to open surgery, with shorter hospital stays and reduced pain. While port site recurrences are a concern, they can be prevented, suggesting favorable short-term outcomes for laparoscopic approaches.
Area of Science:
- Minimally Invasive Surgery
- Surgical Oncology
- Colorectal Surgery
Background:
- The use of laparoscopic colorectal surgery, especially for malignancy, remains a subject of debate.
- Prospective evaluation of laparoscopic versus open conventional surgery is needed to clarify outcomes.
Purpose of the Study:
- To prospectively compare the postoperative outcomes, including short- and medium-term results, of laparoscopic colorectal surgery versus open conventional surgery.
- To evaluate complications, recurrence rates, and survival probabilities between the two surgical approaches.
Main Methods:
- A prospective study included 310 consecutive patients (150 laparoscopic, 160 open).
- Patients chose their treatment modality after informed consent.
- Follow-up averaged 34.2 months.
Main Results:
- Laparoscopic surgery had a longer operative time (251 vs. 175 min) but a shorter hospital stay (10.5 vs. 13.3 days).
- Minor complication rates were lower in the laparoscopic group (3.6% vs. 7.5%), with no significant difference in major complications or mortality.
- Local recurrence rates were lower after laparoscopic surgery (3% vs. 9.2%), and 36-month survival was comparable (0.74% vs. 0.66%).
Conclusions:
- Laparoscopic colorectal surgery demonstrated similar morbidity and mortality to open surgery, with reduced pain and shorter hospital stays.
- Lower local recurrence rates were observed with laparoscopic surgery, though port site recurrences require prophylactic measures.
- Short- and medium-term results favor laparoscopic surgery, but long-term oncological outcomes require further investigation through randomized trials.
