Sigmoidectomy: A Laparoscopic Approach To Colorectal Surgery

Colorectal surgeries have witnessed significant advancements in recent years, allowing for less invasive procedures with faster recovery times. Sigmoidectomy, a surgical procedure involving the removal of the sigmoid colon, has become increasingly common for treating conditions such as diverticulitis, colorectal cancer, and inflammatory bowel disease. In this article, we will explore the laparoscopic approach to sigmoidectomy, which offers several advantages over traditional open surgery. We will also delve into the anatomy of the sigmoid colon and provide insights into the procedure’s benefits, risks, and recovery.

Anatomy Of The Sigmoid Colon

The part of the big gut between the descending colon and the rectum is called the sigmoid colon. Its distinctive S-shape allows for efficient absorption of water and electrolytes, while also facilitating the storage and transportation of fecal matter. The sigmoid colon measures approximately 15 to 60 centimeters in length and is characterized by its tortuous nature.

The sigmoid colon receives its blood supply from the sigmoid arteries, which arise from the superior rectal arteries. Lymphatic drainage occurs through the sigmoid lymph nodes, which ultimately lead to the inferior mesenteric lymph nodes. Understanding the intricate anatomy of the sigmoid colon is essential for performing a successful sigmoidectomy while minimizing the risk of complications.

Sigmoidectomy: A Laparoscopic Approach

Laparoscopic sigmoidectomy, also known as keyhole surgery, is a minimally invasive technique that offers numerous advantages over traditional open surgery. The procedure involves making several small incisions in the abdomen, through which a laparoscope (a thin tube with a camera) and surgical instruments are inserted. The surgeon navigates through the abdominal cavity, visualizes the internal structures on a monitor, and performs the necessary resection of the sigmoid colon.

One of the main benefits of laparoscopic sigmoidectomy is its reduced invasiveness. The smaller incisions reduce postoperative agony, blood loss, and the likelihood of infection. Additionally, the improved cosmetic outcome with minimal scarring is appreciated by many patients. Laparoscopic sigmoidectomy also lets people heal faster and spend less time in the hospital than open surgery, so they can get back to their normal lives sooner.

During the procedure, the surgeon carefully identifies the sigmoid colon, its blood vessels, and surrounding structures. The affected portion of the sigmoid colon is resected, and the remaining healthy ends are joined together using stapling devices or sutures. In some cases, a temporary colostomy may be necessary to divert stool while the anastomosis heals. This temporary colostomy is later reversed in a separate procedure.

Recovery And Potential Risks

In comparison to open surgery, laparoscopic sigmoidectomy typically results in less discomfort and a speedier recovery. The hospital stay is usually shorter, ranging from a few days to a week, depending on individual factors. Pain medications and antibiotics may be prescribed to manage discomfort and prevent infection. Patients are encouraged to gradually resume their normal activities, but heavy lifting and strenuous exercise should be avoided for several weeks.

Laparoscopic sigmoidectomy is a type of surgery, so there are risks that could happen. Some of these are bleeding, infection, damage to organs or blood vessels nearby, and leaks at the anastomosis. But these risks don’t happen very often and can often be lessened by having a skilled expert and using the right methods.

It is essential for patients to follow the postoperative instructions provided by their healthcare team to ensure a smooth recovery. This includes maintaining a balanced diet, staying hydrated, and attending follow-up appointments to monitor healing and address any concerns.


Laparoscopic sigmoidectomy has revolutionized colorectal surgery, offering a less invasive alternative to open surgery for conditions affecting the sigmoid colon. With its advantages of reduced pain, shorter hospital stays, and faster recovery times, this laparoscopic approach has become increasingly popular. However, it is important for patients to discuss the procedure thoroughly with their healthcare team, considering individual circumstances and potential risks. By understanding the anatomy of the sigmoid colon and the benefits of laparoscopic sigmoidectomy, patients can make informed decisions and be well-prepared for successful surgery and recovery.
