Anterior Resection

Colorectal cancer may involve the rectum, which forms the last part of the large intestine. When a tumour develops in the upper or middle portion of the rectum, anterior resection is often considered as part of treatment. The purpose of this operation is to remove the diseased segment while allowing the bowel to continue functioning through its natural pathway.

Before this surgery is planned, several factors are taken into consideration. These include scan findings, colonoscopy reports, and the general health of the patient. Based on this information, doctors decide whether the tumour can be removed safely and whether bowel continuity can be maintained after surgery.

Anterior resection involves removing the part of the rectum that contains the tumour. Along with this segment, surgeons also take a margin of surrounding tissue and nearby lymph nodes. This helps ensure complete tumour removal and accurate pathological staging.

Once the portion of the bowel that is affected has been removed, the other parts of the bowel are then joined. This reconnection restores the passage for stool.

The surgery may be performed through an open approach or with minimally invasive techniques, such as laparoscopy or robotic assistance. The decision depends on the specifics of the case rather than a single standard method.

Anterior resection is considered when the tumour is located in the upper or middle part of the rectum, where it can be removed without involving the anal sphincter. Preserving this structure supports normal control over bowel movements after the operation.

Doctors may suggest this procedure in situations, such as:

• Tumours located in the upper or mid rectum
• Disease that can be removed with a safe margin of surrounding tissue
• Cases where the bowel can be reconnected without difficulty
• Situations where lymph nodes need to be removed for staging
• Patients who are medically fit for surgery

The tissue removed during surgery is examined in the laboratory. This helps confirm the diagnosis and determine the stage of the disease. At Gleneagles Hospitals, this stage is carefully done to support further treatment planning and ongoing care.

The suitability of this treatment option differs in each patient. This is determined by the tumour and the condition of the patient.

The candidates for this treatment include:

• Patients with tumors that are situated farther away from the anal opening
• Patients without extensive involvement of adjacent organs
• Patients with tumours that can be removed according to the imaging results
• Patients considered fit for the treatment after assessment
• Patients with conditions that make the reconnecting of the bowel feasible

Each patient is considered carefully before the decision is made.

Certain conditions make this treatment unsuitable.

Anterior resection may not be suitable in patients who:

• Have tumours very close to the anal region
• Show extensive involvement of surrounding structures
• Are not medically stable for surgery
• Have serious uncontrolled health conditions
• Present with complications that require urgent intervention

In such cases, the treatment plan is adjusted based on clinical need.

Anterior resection is carried out by a specialised surgical team in an operating theatre. The process includes preparation, the surgical steps, and care after the procedure. A structured sequence is followed, where preparation, intervention, and monitoring are carried out carefully, similar to other procedures performed with guided techniques and close observation.

Preparation starts in advance of the surgery date. Patients are assessed to confirm they are fit for the procedure. This may include:

• Review of the patient’s medical history and medications they are currently on
• Blood tests and imaging investigations
• Advice on the need to fast before the surgery
• Preparation of the bowel, if necessary, if they are told to do so
• Consultation with the anaesthesia team

At Gleneagles Hospitals, this is done with clear communication and supportive care.

The surgery is performed under general anaesthesia.

The process usually involves the following steps:

• Accessing the abdominal cavity
• Identifying the affected portion of the rectum
• Removing the tumour along with nearby tissue and lymph nodes
• Joining the remaining parts of the bowel

In some instances, a stoma might be formed to facilitate the healing process.

The duration of the procedure varies with respect to the complexity of the procedure. Anterior resection as part of colorectal cancer treatment at Gleneagles Hospitals is done by experienced teams with close monitoring.

The patient is observed in the recovery area and then transferred to the ward. The length of time spent in the hospital depends on the patient's state of recovery.

During this period:

• Vital signs are constantly monitored.
• Pain relief is provided.
• Fluids and food are gradually reintroduced.
• Physical activities are encouraged.
• Bowel function is monitored.

Before discharge, patients are given instructions on home care and follow-up.

Like any other surgical procedure, anterior resection has its risks. The patient is monitored before and after the surgery.

The possible complications that can arise from the surgery include:

• Bleeding
• Infection
• Leakage from the point where the bowel was joined
• Change in bowel habits
• Injury to other organs
• Blood clots

Most patients recover from the surgery smoothly. Any complications that develop are quickly noticed and treated by the experienced team at Gleneagles Hospitals during regular followups.

When used in appropriate cases, this procedure offers several advantages.

It may help to:

• Remove the tumour effectively
• Maintain the natural passage for stool
• Avoid permanent stoma in many situations
• Provide information through lymph node analysis
• Assist in planning further treatment

The results depend on factors, such as stage of disease and overall health.

Anterior resection at Gleneagles Hospitals is performed as part of a coordinated colorectal cancer care program. The procedure is handled by experienced surgeons with support from different specialties.

Care includes:

• Access to minimally invasive surgical techniques
• Detailed preoperative planning
• Well-equipped operating rooms
• Monitoring and care after surgery
• Support from oncology and diagnostic teams
• Patients are guided throughout the process, from evaluation to follow-up.

Anterior resection is a standard surgical option for cancers located in the upper and middle rectum. The procedure removes the affected segment and restores bowel continuity in suitable cases.

Careful selection, planning, and follow-up play an important role in recovery. At Gleneagles Hospitals, the focus remains on safe surgery and coordinated patient care.
