A proctosigmoidectomy, Hartmann's operation or Hartmann's procedure is the surgical resection of the rectosigmoid colon with closure of the anorectal stump and formation of an end colostomy. It was used to treat colon cancer or inflammation (proctosigmoiditis, proctitis, diverticulitis, volvulus, etc.).
CT scan showing extensive diverticulosis of the sigmoid colon Diverticular disease Whole slide of a transverse section of the left colon with diverticulosis. Diverticulosis is defined by the presence of multiple pouches (diverticula) in the colon. [22] In people without symptoms, these are usually found incidentally during other investigations.
Diverticulitis typically presents with lower quadrant abdominal pain of a sudden onset. [1] Patients commonly have elevated C-reactive protein and a high white blood cell count. [10] In Asia it is usually on the right (ascending colon), while in North America and Europe, the abdominal pain is usually on the left lower side (sigmoid colon).
Fecal calprotectin, a marker of colon inflammation, may be elevated. Computed tomography of the abdomen is not routinely necessary, but may show thickening or inflammation in the distal colon (sigmoid colon) with associated diverticulosis. Treatment may consist of antibiotics, aminosalicylates (mesalamine), or prednisone. In rare cases, surgery ...
A lower anterior resection, formally known as anterior resection of the rectum and colon and anterior excision of the rectum or simply anterior resection (less precise), is a common surgery for rectal cancer and occasionally is performed to remove a diseased or ruptured portion of the intestine in cases of diverticulitis.
Acute diverticulitis is thought to arise from either trauma or lack of blood flow to the existing diverticulum in the colon. The traumatic theory proposes that a fecalith, which is a hardened fecal matter, becomes trapped in a diverticulum, leading to colonic mucosa abrasion and local inflammation.
Hinchey Classification is used to describe perforations of the colon due to diverticulitis. The classification was developed by Dr. E John Hinchey (1934–present), a general surgeon at the Montreal General Hospital and professor of surgery at McGill University. Diverticulosis (the presence of bowel diverticula) is an essentially ubiquitous ...
About 10% of cases have a more serious cause including gallbladder (gallstones or biliary dyskinesia) or pancreas problems (4%), diverticulitis (3%), appendicitis (2%) and cancer (1%). [2] More common in those who are older, ischemic colitis , [ 5 ] mesenteric ischemia , and abdominal aortic aneurysms are other serious causes.
