Colectomy (col- + -ectomy) is the surgical removal of any extent of the colon, the longest portion of the large bowel. Colectomy may be performed for prophylactic, curative, or palliative reasons. Indications include cancer, infection, infarction, perforation, and impaired function of the colon. Colectomy may be performed open, laparoscopically, or robotically. Following removal of the bowel segment, the surgeon may restore continuity of the bowel or create a colostomy. Partial or subtotal colectomy refers to the removal of a portion of the colon, while total colectomy involves removal of the entire colon.

Indications

[edit]

Common indications for colectomy include:[1][2]

Procedure

[edit]

Pre-operative Preparation

[edit]

Prior to surgery, patient typically undergo preoperative bloodwork, including a complete blood count and type and screen of blood type. Diagnostic imaging may include colonoscopy or CT scans of the abdomen and pelvis. In cancer patients, tattooing of lesions via colonoscopy is common prior to colectomy.[1] For non-emergent procedures, patients are typically instructed to follow a clear liquid diet or fast, and take a mechanical bowel preparation (oral osmotic agents or laxative) to clear the bowels prior to surgery.[4][1] Antibiotics may also be prescribed ahead of surgery.[2]

Operation

[edit]

Traditionally, colectomy is performed via an abdominal incision, a technique known as laparotomy. Minimally invasive colectomy, by means of laparoscopy is a well-established procedure in many medical centers.[5][6] Robot-assisted colectomy is growing both in scope of indications and popularity.[7]

Laparoscopic Approach

[edit]

As of 2012, more than 40% of colon resections in United States are performed via laparoscopic approach.[5] For laparoscopic colectomy, typical operative technique involves 4-5 incisions made in the abdomen. Trochars are introduced to gain access to the peritoneal cavity and serve as ports for the laparoscopic camera and other instruments.[8] Studies have proven the feasibility of single port access colectomy, which would require only one small incision, but no clear benefit in terms of outcome or complication rate has been demonstrated.[6][9]

Resection

[edit]

The first step is to free, or mobilize, the portion of the bowel that is to be resected. This is done by dissection and removal of the mesentery and other peritoneal attachments. Resection of any part of the colon entails mobilization and sealing off, or ligation, of the blood vessels suppling the portion of colon to be removed.[8] A stapler is typically used to cut across the colon so as to prevent spillage of intestinal contents into the peritoneal cavity.[10] Colectomy as treatment for colorectal cancer also includes lymphadenectomy, which is usually accomplished via excision of the mesocolon, the fatty tissue containing blood supply, lymphatics, and nerves to the colon.[citation needed]

Primary Anastomosis vs Colostomy

[edit]

When the resection is complete, the surgeon has the option of restoring continuity of the bowel by stitching or stapling together the cut ends of the bowel (primary anastomosis), or creating a colostomy, an opening of the bowel to the abdominal wall.[1] When colectomy is performed as part of damage control surgery in life-threatening trauma resulting in destructive colon injury, the bowel may be left in discontinuity temporarily to allow for further resuscitation of the patient before returning to the operating room for definitive repair (anastomosis or colostomy).[11]

Several factors are taken into account when deciding between anastomosis or colostomy, including:

  • Circumstances of the operation (elective vs emergency); In many cases, emergency resection of colon with anastomosis needs to be done and this carries a higher complication rate since proper bowel preparation is not possible in emergency situations[citation needed]
  • Disease being treated; (i.e., no colectomy surgery can cure Crohn's disease, because the disease usually recurs at the site where the healthy sections of the large intestine were joined. For example, if a patient with Crohn's disease has a transverse colectomy, their Crohn's will usually reappear at the resection site of the ascending and descending colons.)[citation needed]
  • Acute physiological state of the patient;
  • Impact of living with a colostomy, albeit temporarily;
  • Use of a specific preoperative regimen of low residue diet and laxatives (so-called "bowel prep").

Colostomy is always safer, but places a societal, psychological and physical burden on the patient. The choice is by no means an easy one and is rife with controversy, being a frequent topic of heated debate among surgeons all over the world.[citation needed]

Complications and Risks

[edit]

All surgery involves risk of serious complications, including bleeding, infection, damage to surrounding structures, and death. Additional complications for colectomy include:[1][2]

  • Damage to adjacent structures such as ureter, bowel, spleen, etc.
  • Need for further operations
  • Conversion of primary anastomosis to ostomy
  • Anastomotic dehiscence or leak
  • Inability to resect colon as intended
  • Cardiopulmonary or other organ failure
  • Death

Anastomotic Dehiscence

[edit]

An anastomosis carries the risk of dehiscence, or breakdown of the surgical connection. Contamination of the peritoneal cavity with fecal matter as a result of the disrupted anastomosis can lead to peritonitis, sepsis or death.[citation needed] A number of factors may increase the risk of anastomotic dehiscence. Basic surgical principles include ensuring a good blood supply to the opposing ends, and a lack of tension at the join. The use of NSAIDS for analgesia following gastrointestinal surgery remains controversial, given mixed evidence of an increased risk of leakage from any bowel anastomosis created. This risk may vary according to the class of NSAID prescribed.[12][13][14]

Types

[edit]
Right hemicolectomy
Left hemicolectomy
  • Right hemicolectomy and left hemicolectomy refer to the resection of the ascending colon (right) and the descending colon (left), respectively. When middle colic vessels and transverse colon are also resected, it may be referred to as an extended hemicolectomy.[15] Main limitation to perform a left extended colectomy is the difficulty to achieve a colorectal anastomosis afterwards. Different techniques has been proposed to solve this issue such as Deloyer's or Rosi-Cahil techniques.[16]
Transverse colectomy
  • Transverse colectomy is also possible, though uncommon.[17]
Sigmoidectomy
Proctosimoidectomy
  • Sigmoidectomy is a resection of the sigmoid colon, sometimes including part or all of the rectum (proctosigmoidectomy). When a sigmoidectomy is followed by terminal colostomy and closure of the rectal stump, it is called a Hartmann operation; this is usually done out of impossibility to perform a "double-barrel" or Mikulicz colostomy, which is preferred because it makes "takedown" (reoperation to restore normal intestinal continuity by means of an anastomosis) considerably easier.[18]
Total colectomy
Total proctocolectomy
  • When the entire colon is removed, this is called a total colectomy, also known as Lane's Operation.[19] If the rectum is also removed, it is a total proctocolectomy.
  • Subtotal colectomy is resection of part of the colon or a resection of all of the colon without complete resection of the colon.[20]

History

[edit]

Sir William Arbuthnot-Lane was one of the early proponents of the usefulness of total colectomies, although his overuse of the procedure called the wisdom of the surgery into question.[21]

A report of the first laparoscopically assisted colectomies was published by Jacobs et al. in 1991.[6][22] While initial concerns were raised about the incidence of port site reoccurrence of tumors after laparoscopic colectomy for cancer, it was later found to be similar to that of wound implant of tumor cells as a result of open colectomy for cancer.[6] By the mid 2000s, several studies had been published demonstrating that laparoscopic colectomy was at least as safe as open colectomy, and could in fact lead to shorter post-operative recovery times when performed by a skilled surgeon.[6]
