Transanal hemorrhoidal dearterialization is an alternative to operative hemorrhoidectomy.

BACKGROUND: Transanal hemorrhoidal dearterialization (THD), a new approach for patients who would otherwise require an operative hemorrhoidectomy, accomplishes hemorrhoidal symptom relief with far less postoperative pain than an operative hemorrhoidectomy. METHODS: THD, an ambulatory procedure, employs a specially designed proctoscope coupled with a Doppler transducer to allow identification and suture ligation of the hemorrhoidal arteries. RESULTS: Sixty patients between ages 22 and 87 were treated. Bleeding was fully corrected in 88%, protrusion in 92%, and pain in 71%. Two patients (3%) failed to improve with THD. Complications included pain resulting in greater than 2 days loss of work in 5 patients, postoperative perirectal thromboses developed in 4 patients, and an anal fissure developed in 1 patient. CONCLUSIONS: THD was an effective alternative to operative hemorrhoidectomy. It may be the only option for patients where an operative hemorrhoidectomy is contraindicated because of incontinence.

Anorectal Crohn's disease: surgical and medical management.

In some patients with Crohn's disease the anorectal complications are the major cause of symptoms and morbidity. Anorectal Crohn's disease may be present in patients with intestinal Crohn's disease, may be the initial manifestation of the disease, or rarely occurs without involvement of Crohn's disease elsewhere in the intestinal tract. The pathogenesis of these anorectal complications remains to be clarified. The anorectal examination is very important in the assessment of patients with suspected or documented inflammatory bowel disease. Meticulous physical examination, examination under anaesthesia and radiological imaging modalities may be utilised to specifically identify the location of abscesses and fistulae. Treatment strategy should be directed toward symptomatic relief; the most important symptom is pain. In most patients this pain will be attributable to an incompletely drained rectal abscess. Simple incision and drainage procedures are often all that is required as initial treatment of anorectal abscesses. Treatment of the anorectal fistulae that occur secondary to Crohn's disease requires combined medical and surgical therapy. Drug therapy is more often initiated for Crohn's disease that involves other areas of the gastrointestinal tract. The anorectal manifestations often respond to these same medications. Lay-open procedures (fistulotomies) are often all that is required surgically for simple (low) anorectal fistulae. High (complex) fistulae that involve large portions of the anorectal muscular ring are more difficult to treat. Patients with these fistulae must be treated on an individual basis, usually local surgical therapy combined with a medical regimen. Many surgical procedures are performed and many classes of medications are utilised on patients with these complex anorectal fistulae. Choosing the appropriate surgical and medical interventions is often quite difficult. Although sulfasalazine, mesalazine and corticosteroids have no lasting or maintenance value for fistulae, the immunosuppressive agents mercaptopurine, azathioprine and cyclosporin, the antibacterial metronidazole and the anti-tumour necrosis factor-alpha monoclonal antibody infliximab have varying degrees of effect. The goal of the combined regimen is to cure the fistula, or at least make it minimally symptomatic, without altering the patient's continence.

Variations in colon and rectal surgical mortality. Comparison of specialties with a state-legislated database.

PURPOSE: This study was designed to examine variations in operative mortality among surgical specialists who perform colorectal surgery. METHODS: Mortality rates were compared between six board-certified colorectal surgeons and 33 other institutional surgeons using comparable colorectal procedure codes and a validated database indicating patient severity of illness. Thirty-five ICD-9-CM procedure codes were used to identify 2,805 patients who underwent colorectal surgery as their principal procedure between July 1986 and April 1994. Atlas, a state-legislated outcome database, was used by the hospital's Quality Assurance Department to rank the Admission Severity Group (ASG) of 1,753 patients from January 1989 to April 1994 (higher ASG, 0 to 4, indicates increasing medical instability). RESULTS: Colorectal surgeons had an eight-year mean in-hospital mortality rate of 1.4 percent compared with 7.3 percent by other institutional surgeons (P = 0.0001). There was a significantly lower mortality rate for colorectal surgeons compared with other institutional surgeons in ASG 2 (0.8 and 3.8 percent, respectively; P = 0.026) and ASG 3 (5.7 and 16.4 percent, respectively; P = 0.001). CONCLUSIONS: Board-certified colorectal surgeons had a lower in-hospital mortality rate than other institutional surgeons as patients' severity of illness increased.
