Large Intestine (Colon)
The colon or large intestine is a key part of the digestive system. Here are its structural details:
The colon is 5 feet long and divided into several parts:
Diverticula:
Diverticula, the small pouches, are most commonly found in the sigmoid colon, but can also develop anywhere else in the colon. They form when the inside lining of the intestine pushes into weak spots in the outer wall.
Understanding this anatomy is crucial to diagnosing and treating diverticula.
The table below presents the various types of diverticulectomy surgery:
Type of Diverticulectomy | Description | Advantages | Indications |
---|---|---|---|
Open (Traditional) Diverticulectomy | A large incision is made in the abdomen to access the colon; the affected section is removed and the remaining healthy ends of the colon are reconnected |
|
|
Laparoscopic Diverticulectomy | The diseased section of the colon is removed after making several small incisions and using specialized instruments. It’s a minimally invasive procedure |
|
|
Robotic-assisted Diverticulectomy | It is similar to a laparoscopic surgery, but done with the use of a robotic system |
|
|
Sigmoid Colectomy | A specific type of diverticulectomy that focuses on sigmoid colon removal; can be open, laparoscopic, or robotic-assisted |
| Recurrent/complicated diverticulitis in the sigmoid colon |
Primary Bowel Resection with Anastomosis | Removal of the diseased section of the colon, followed by reconnection of the healthy ends |
|
|
Bowel Resection with Colostomy | Diverting the colon to an abdominal wall opening; is suitable when there is severe infection or when the tissues are not healthy enough for a safe anastomosis |
|
|
Choosing the types of surgery is done on the basis of the severity of the disease, the surgeon’s expertise, and the overall health and preferences of the patient.
