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.
[5] [6] The operation can be done by open surgery, laparoscopic or Robot-assisted. [7] For lower down tumours in the middle and lower third of the rectum a new procedure has been developed known as Transanal-Total Mesorectal Excision (TaTME). Instead of the dissection via the abdomen TaTME combines an abdominal and transanal endoscopic approach ...

The procedure is still almost always carried out via laparoscopic approach. [15] However, increasingly some surgeons use robotic surgery to conduct the procedure. [ 5 ] Some surgeons claim that the use of robotic surgery makes ventral rectopexy less technically demanding, because it requires careful dissection and suture placement in a tight ...
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.).
To reduce the incidence of death and suffering of the patients associated with the APR procedure, Henri Albert Hartmann introduced the anterior resection of the rectum by preserving the distal rectum and anal sphincters, while producing end-sigmoid colostomy. There were attempts to restore bowel continuity by joining the proximal colon with the ...
By the mid 1880's, hundreds of colectomies had been performed, with a fatality rate between 50 and 60% (lower for those performed in cases of cancer). Dr. Robert Weir suggested in his 1886 case report on the resection of a rectal tumor that shock from the operation and leakage of intestinal contents both during and after surgery contributed to ...
This laparoscopic surgical procedure was the first laparoscopic organ resection reported in medical literature. In 1981, Semm, from the gynecological clinic of Kiel University, Germany, performed the first laparoscopic appendectomy. Following his lecture on laparoscopic appendectomy, the president of the German Surgical Society wrote to the ...
