Colorectal cancer & laparoscopic surgery: 10 patient questions

Early colorectal cancer may cause no symptoms. Possible warning signs include persistent changes in bowel habit, blood in the stool, unexplained weight loss, abdominal discomfort or iron-deficiency anaemia.

Bleeding can also come from haemorrhoids, a fissure or inflammation. Symptoms alone cannot distinguish these causes. Arrange assessment for unexplained or recurrent bleeding; heavy bleeding with faintness needs emergency care.

Colonoscopy allows the doctor to inspect the bowel and usually take a tissue sample. Laboratory examination of that sample confirms the diagnosis. Blood tests and tumour markers alone cannot confirm or exclude colorectal cancer.

CT scans assess possible spread. Rectal cancer often also requires pelvic MRI to plan treatment. Bring the biopsy report, endoscopy report and original scans to your consultation.

Stage describes how deeply the cancer has grown and whether it has reached lymph nodes or distant organs. Scans provide an initial assessment; examination of the removed tissue can refine the stage.

The chance of cure depends on stage, tumour biology, whether complete removal is possible and the response to treatment. Early disease often has better prospects. No single percentage applies to everyone; follow-up checks for recurrence even after apparently complete treatment.

For suitable colon cancers, laparoscopic surgery by an experienced team can achieve comparable cancer outcomes to open surgery while often reducing wound pain and recovery time. Both must remove the tumour with appropriate margins and lymph nodes.

Laparoscopic surgery uses small abdominal incisions under general anaesthesia. It is different from a diagnostic colonoscopy passed through the anus. Rectal surgery requires careful case selection and the same cancer-surgery principles.

The decision depends on the tumour, previous operations, adhesions, general fitness and whether surgery is urgent. A large or invasive tumour may favour an open approach.

If visibility, bleeding or anatomy makes continuing by laparoscopy unsafe, the surgeon may enlarge the incision. Conversion is a safety decision, not necessarily a complication or failure.

Not everyone needs a stoma. A temporary opening may protect a low bowel join or be needed during emergency surgery. A permanent stoma may be necessary if the anus or its sphincter muscles must be removed, or reconnection is unsafe.

The likely need is discussed before surgery. Closing a temporary stoma depends on healing, cancer treatment and fitness; closure is not guaranteed for every patient.

Treatment differs between colon and rectal cancer. Colon surgery is often followed by chemotherapy when lymph nodes are involved or certain other risk factors are present. Radiotherapy is not routinely used for colon cancer.

For some rectal cancers, chemotherapy and/or radiotherapy is given before surgery. The multidisciplinary team uses stage, tumour testing and your health to decide the sequence; needing surgery does not automatically mean needing every treatment.

Possible complications include bleeding, infection, blood clots, slow bowel recovery and a leak from the bowel join. Individual risk depends on the operation and your health.

Seek urgent assessment for worsening abdominal pain, fever with deterioration, repeated vomiting, heavy bleeding or increasing swelling with inability to pass gas. Chest pain, breathing difficulty or collapse require emergency care. Do not wait for an online or WhatsApp reply.

Expect several days in hospital after bowel resection, with longer stays for complex surgery or complications. Discharge depends on drinking and eating sufficiently, moving safely and controlling pain.

Recovery at home usually takes weeks. Desk work may be possible before strenuous work. Early walking and prescribed pain relief help, but lifting, driving and return-to-work timing must be agreed with your team.

Food is reintroduced according to your operation and recovery. Smaller meals and enough fluids may help; fibre advice must follow your team’s plan, especially with a stoma.

Looser, more frequent or urgent bowel movements can occur, particularly after rectal surgery. Adjustment may take months and some changes persist. Report ongoing problems so diet, medicines or bowel rehabilitation can be tailored to you.
