[Pull-through transection and anastomosis for early lower rectal cancer using double stapling technique]

Area of Science:

• Colorectal Surgery
• Surgical Oncology
• Gastrointestinal Oncology

Context:

• Early lower rectal cancer presents surgical challenges regarding tumor resection and sphincter preservation.
• Traditional low anterior resection techniques can be complex, requiring precise control of transection and anastomosis.
• Minimally invasive approaches are continuously being explored to improve outcomes in rectal cancer surgery.

Purpose:

• To evaluate the efficacy and safety of pull-through transection and double stapling anastomosis in patients with early lower rectal cancer.
• To compare the outcomes of this technique with traditional trans-abdominal transection methods.
• To assess the oncological and functional results, including recurrence rates and anastomotic complications.

Summary:

• A study involving 25 patients with early lower rectal cancer utilized pull-through transection and double stapling anastomosis.
• The average tumor distance from the dentate line was 3.2 cm, with an average tumor diameter of 2.8 cm.
• The technique demonstrated precise control of the cutting line, with negative resection margins in all cases. One instance of anastomotic leakage was managed conservatively. Local recurrence occurred in 4%, with metastasis rates of 12% for liver and 8% for lung. Mild fecal incontinence was observed in 7 cases.

Impact:

• Pull-through transection and double stapling anastomosis provide a simpler and more controlled method for rectal cancer resection.
• This technique may lead to improved surgical outcomes and potentially reduce complications associated with traditional methods.
• Further research can explore long-term functional results and oncological control in a larger patient cohort.
