Aim and objective: This paper was conducted to examine the results of laparoscopic intersphincteric resection and colon shaping for low rectal cancer treatment in adults.
Materials and methods: Data were collected, including general characteristics, preoperative and postoperative characteristics, and long-term treatment outcomes. The Kaplan–Meier survival analysis was performed to assess the survival rate of 48 months after surgery.
Results: Of 43 patients with low rectal cancer, subtotal intersphincteric resection was the primary surgical method at 37.2%. The colon was mainly shaped “J” at 51.2% of the patients. According to Kirwan classification, there were 83.7% of the patients at grade I; and this rate decreased to 62.9% after surgery (p <0.05). According to Wexner score, before surgery, 62.8% of the patients had a score <5, which reduced to 48.8% after surgery (p >0.05). The mean survival time was 41.53 ± 2.37 months, with a cumulative survival probability of 48 months of 78.8%. There was no difference in survival rate between patients with different stages of cancer and colon shaping.
Conclusion: Laparoscopic intersphincteric resection and colon shaping were effective in low rectal cancer treatment. Colon shaping was an effective method of improving bowel function in cases of subtotal or total intersphincteric resection.
