RATIONALE: Laparoscopic-assisted resection is a less invasive type of surgery for rectal cancer and may have fewer side effects and improve recovery. It is not yet known whether laparoscopic-assisted resection is more effective than open resection in treating patients with rectal cancer.
PURPOSE: This randomized phase III trial is studying laparoscopic-assisted resection to see how well it works compared with open resection in treating patients with stage IIA, stage IIIA, or stage IIIB rectal cancer.
- To test the hypothesis that laparoscopic-assisted resection is not inferior to open resection, based on a composite primary endpoint of oncologic factors that are indicative of a safe and feasible surgical resection, in patients with stage IIA, IIIA, or IIIB rectal cancer.
- To compare the patient-related benefit of laparoscopic-assisted resection vs open resection, in terms of blood loss, length of stay, and utilization of pain medication.
- To compare the disease-free survival and local pelvic recurrence at 2 years.
- To compare the quality of life, sexual function, and bowel and stoma function.
OUTLINE: This is a multicenter study. Patients are stratified according to site of primary tumor (high vs middle vs low rectum), registering surgeon, and planned operative procedure (low anterior resection vs abdominal perineal resection). Patients are randomized to 1 of 2 treatment arms.
- Arm I: Patients undergo open laparotomy and rectal resection.
- Arm II: Patients undergo laparoscopic-assisted rectal resection. Quality of life is assessed periodically using EORTC Quality of Life Questionnaires (EORTC QLQ-C30 and -CR38), the Linear Analog Self-Assessment (LASA), the Stoma Quality of Life Scale (SQOLS), and the Mayo Bowel Function Questionnaire (MBFQ).
After completion of study treatment, patients are followed periodically for up to 5 years.
Allocation: Randomized, Primary Purpose: Treatment

Management of appendicitis has evolved dramatically in the last 120 years, from McBurney's large incision to minimally invasive laparoscopic appendectomy to hardly noticeable incisions with SILS. As...
Surgical procedures conducted with the aid of computers. This is most frequently used in orthopedic and laparoscopic surgery for implant placement and instrument guidance. Image-guided surgery interactively combines prior CT scans or MRI images with real-time video.
Procedures that avoid use of open invasive surgery in favor of closed or local surgery. These generally involve use of laparoscopic devices and remote-control manipulation of instruments with indirect observation of the surgical field through an endoscope or similar device. With the reduced trauma associated with minimally invasive surgery, long hospital stays may be reduced with increased rates of short stay or day surgery.

Moving a patient into a specific position or POSTURE to facilitate examination, surgery, or for therapeutic purposes.
Therapeutic practices which are not currently considered an integral part of conventional allopathic medical practice. They may lack biomedical explanations but as they become better researched some (PHYSICAL THERAPY MODALITIES; DIET; ACUPUNCTURE) become widely accepted whereas others (humors, radium therapy) quietly fade away, yet are important historical footnotes. Therapies are termed as Complementary when used in addition to conventional treatments and as Alternative when used instead of conventional treatment.

Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start - for example, cancer that begins in the colon is called colon cancer; cancer th...
