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]
- Colorectal cancer
- Colon polyps not amenable to removal by colonoscopic polypectomy
- Diverticulitis and diverticular disease of the large intestine
- Colon perforation or injury, which can occur as a result of trauma
- Bleeding
- Inflammatory bowel disease such as ulcerative colitis or Crohn's disease
- Bowel infarction or ischemia
- Volvulus
- Stricture
- Slow-transit constipation
- Hirschsprung's disease
- Prophylactic colectomy may be indicated in patients with hereditary cancer syndromes such as Familial adenomatous polyposis or Lynch syndrome, and in certain cases of inflammatory bowel disease due to an increased risk of colorectal cancer[3]
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 the cutting and sealing, 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, or removal of surrounding lymph nodes, which may be done for staging of the cancer or removal of cancerous nodes. More extensive lymphadenectomy is sometimes accomplished by removal of the mesocolon, the fatty tissue adjacent to the colon which contains blood supply, lymphatics, and nerves to the colon.[11][12]
Primary anastomosis vs colostomy
[edit]When the resection is complete, the surgeon has the option of reconnecting the bowel by stitching or stapling together the cut ends of the bowel (primary anastomosis), or performing a colostomy to create a stoma, an opening of the bowel to the abdominal wall that provides and alternate exit for the contents of the gastrointestinal tract.[1] When colectomy is performed as part of damage control surgery in life-threatening trauma resulting in destructive colon injury, the surgeon may opt to leave the cut ends of the bowel sealed and disconnected for a short period of time to allow for further resuscitation of the patient before returning to the operating room for definitive repair (anastomosis or colostomy).[13]
Several factors are taken into account when deciding between anastomosis or colostomy, including:
- Urgency of presentation;
- Contamination of the operative field;
- Technical difficulty of the anastomosis;
- Disease severity and stage;
- Physiologic considerations: pelvic floor function, length of bowel remaining;
- Patient factors: social support, socioeconomic status, level of education and health literacy, availability of specialist services, and level of functioning.[14]
Giving a patient a colostomy avoids the risk of a failed anastomosis but places a societal, psychological and physical burden on the patient, as a stoma requires special care and consideration.[14]
Complications and risks
[edit]All surgery involves risk of serious complications, including bleeding, infection, damage to surrounding structures, and death. Additional complications associated with colectomy include:
- Damage to adjacent structures such as ureter, bowel, spleen, etc.;
- Need for further operations;
- Conversion of primary anastomosis to colostomy;
- Anastomotic dehiscence or leak;
- Inability to resect colon as intended;
- Cardiopulmonary or other organ failure;
- Death.[1][2]
Anastomotic dehiscence and anastomotic leak
[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 anastomotic leak can lead to peritonitis, sepsis or death. In patients who underwent colectomy as treatment for colorectal cancer, an anastomotic leak increases risk of recurrence of the cancer in the same area and reduces survival in the long-term. A number of factors influence the risk of anastomotic dehiscence, including preservation of blood supply to the cut ends of the bowel, tension on the anastomosis, and the patient's intestinal microbiome, which affects wound healing and potential for surgical site infection.[15]
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.[16][17][18]
Types
[edit]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.[19] 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.[20]
Transverse colectomy is also possible, though uncommon.[21]
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.[22]
When the entire colon is removed, this is called a total colectomy, also known as Lane's Operation.[23] 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.[24]
History
[edit]The first concepts of colon surgery were thought to have originated in the 15th century as a means to relieve obstructed bowel. The first reported ostomy, performed in 1776 by Pillore of Rouen as an attempt to circumvent blockage caused by a rectal tumor, was done at the insistence of the patient despite opposition from other doctors. While this initial attempt resulted in the death of the patient after only 20 days, subsequent attempts in the following years were more successful.[25]
Jean Francois Reybard performed the first successful end-to-end anastomosis following resection of the sigmoid colon in 1823. Largely criticized as dangerous, Reybard's procedure went against standard protocol of the day, namely resection with stoma and distal closure. [15]
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.[26]
A report of the first laparoscopically assisted colectomies was published by Jacobs et al. in 1991.[6][27] 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]
