Laparoscopic Colectomy
What is Laparoscopic Colectomy? A colectomy removes part or all of the colon (large intestine). It is performed for colon cancer, large polyps that cannot be removed by colonoscopy, recurrent diverticulitis, and severe Crohn's disease or ulcerative colitis. Typical duration at Iswarya Hospital, OMR Chennai: 2–4 hours. Recovery: 4–6 weeks.
In the laparoscopic approach the surgeon frees the bowel through four or five small ports and removes the specimen through a single short incision, then joins the healthy ends back together. Compared with open colectomy, patients have less pain, start eating sooner and leave hospital earlier, with the same cancer clearance when the operation is for a tumour.

How is Laparoscopic Colectomy performed?
- 1
General anaesthesia is given and a urinary catheter is placed.
- 2
Four or five small ports are inserted and the abdomen is inflated with gas.
- 3
The affected segment of colon is freed from its attachments and its blood vessels are sealed.
- 4
The bowel is divided above and below the diseased section with a stapler.
- 5
The specimen is removed through a 4–6 cm incision, usually low on the abdomen.
- 6
The two healthy ends are joined (anastomosis) with a stapler or sutures; a temporary stoma is created only if the join needs protecting.
What are the benefits of Laparoscopic Colectomy?
- ✓Removes cancer or diseased bowel with a smaller incision than open surgery
- ✓Bowel function returns faster, so eating resumes within 1–2 days
- ✓Hospital stay typically 4–6 days instead of 7–10
- ✓Less pain and a lower risk of wound infection and incisional hernia
- ✓Same lymph-node clearance and cancer outcomes as open surgery
How do you prepare for Laparoscopic Colectomy?
- Colonoscopy, CT scan and blood tests stage the disease and plan the operation.
- A bowel-cleansing preparation and oral antibiotics are taken the day before.
- Stop blood thinners as instructed; continue other medicines unless told otherwise.
- Meet the stoma nurse if there is any chance of a temporary stoma.
- Fast from midnight; clear carbohydrate drinks may be allowed until 2 hours before.
What are the risks and side effects of Laparoscopic Colectomy?
- Leak at the bowel join (anastomotic leak), the most serious complication
- Bleeding, infection or abscess in the abdomen
- Temporary slowing of the bowel (ileus) delaying eating
- Need for a temporary or, rarely, permanent stoma
- Conversion to open surgery if the disease is extensive or the anatomy unclear
Your surgeon will discuss all risks with you before the procedure and take appropriate precautions to minimise them.
What is recovery like after Laparoscopic Colectomy?
- Chewing gum and early walking help the bowel restart.
- Diet advances from fluids to soft food over 2–3 days.
- Injections to prevent blood clots continue for up to 4 weeks after cancer surgery.
- Avoid lifting more than 5 kg for 6 weeks to protect the wound.
- The pathology report is reviewed at the 2-week visit to decide on any further treatment.
Frequently asked questions about Laparoscopic Colectomy
Will I need a colostomy bag?
Most laparoscopic colectomies are completed with a direct join and no bag. A temporary stoma is used in around 10–15% of cases, usually for very low rectal joins or emergency surgery, and is reversed after a few months.
Is keyhole surgery safe for colon cancer?
Yes. Large trials show laparoscopic colectomy removes the same amount of bowel and lymph nodes as open surgery, with identical cancer survival and fewer wound complications.
How will my bowel habit change?
After removing part of the colon, stools may be looser and more frequent for a few weeks to months. This settles as the remaining bowel adapts. Right-sided removals cause fewer changes than left-sided ones.
When can I return to work?
Desk work in 3–4 weeks; physically demanding work in 6–8 weeks. Driving is safe once you can do an emergency stop without pain, usually after 2–3 weeks.
Where can you get Laparoscopic Colectomy in Chennai?
Iswarya Hospital's General & Laparoscopic Surgery department performs a wide range of procedures using minimally invasive (keyhole) techniques for faster recovery, less pain, and shorter hospital stays — including hernia repair, gallbladder removal, appendectomy, and piles/fistula surgery.
