Summary
Laparoscopic resection (LR) for rectal cancer offers faster patient recovery and similar overall morbidity compared to open resection (OR). This minimally invasive approach shows no adverse oncologic outcomes, with a lower local recurrence rate.
Area of Science:
- Colorectal Surgery
- Surgical Oncology
- Minimally Invasive Surgery
Background:
- The efficacy of laparoscopic resection (LR) for extraperitoneal rectal cancer remains uncertain.
- Comparison between laparoscopic and open resection (OR) for low and midrectal cancer is needed.
Purpose of the Study:
- To compare perioperative and long-term outcomes of laparoscopic resection (LR) versus open resection (OR) for low and midrectal cancer.
Main Methods:
- A prospective nonrandomized trial was conducted at a single institution.
- 191 patients (98 LR, 93 OR) with low and midrectal cancer were included.
- Follow-up averaged 46.3 months for LR and 49.7 months for OR.
Main Results:
- LR demonstrated significantly faster patient mobilization, flatus passage, stool passage, and oral intake resumption.
- Morbidity and mortality rates were similar between LR and OR groups.
- LR showed a significantly lower local recurrence rate (3.2% vs. 12.6%) and improved survival for stages III and IV rectal cancer.
Conclusions:
- Laparoscopic resection for low and midrectal cancer leads to faster recovery with comparable overall morbidity.
- While anastomotic leakage rates were higher in the LR group, oncologic outcomes were not adversely affected.
- LR presents a favorable alternative to OR, with reduced local recurrence and improved survival in advanced stages.
