Symptomatic hemorrhoids: Current incidence and complications of operative therapy

Hemorrhoidal disease affects more than one million Americans per year. We reviewed the treatment pattern for patients who presented with symptomatic hemorrhoids to our large university-affiliated group practice over a 66-month period. Over 21,000 patients presented to the practice with bleeding, thrombosis, or prolapse. Only 9.3 percent of patients required operative therapy. Conservative therapy was given to 45.2 percent of patients, while rubber band ligation was performed on 44.8 percent of patients. We retrospectively reviewed the complications and length of stay for a subset of patients undergoing operative therapy during the 66-month study period. Postoperative urinary complications (retention or infection) were seen in 20.1 percent of patients. Delayed hemorrhage was seen in 2.4 percent of patients. In-hospital length of stay was 2.5 days, which is approximately two days less than the length of stay found in a similar review of our practice in 1978. We conclude that over 90 percent of symptomatic hemorrhoids can be treated conservatively or with rubber band ligation, and, as surgery is reserved for only the most severe cases, complication rates may not decrease. However, we expect that in-hospital length of stay will continue to decrease over the ensuing years.

The management of procidentia - 30 years' experience

This is a retrospective study evaluating 179 patients with complete rectal prolapse operated on at the University of Minnesota affiliated hospitals from 1953 to 1983 with no mortality. One hundred and two of 138 patients who underwent abdominal proctopexy and sigmoid resection were followed from six months to 30 years with a recurrence rate of 1.9 percent. Twenty-two of the 33 patients who underwent perineal rectosigmoidectomy were followed from six months to three years with no recurrence. Nine patients who underwent abdominal proctopexy and subtotal colectomy because of colonic inertia associated with procidentia were followed from one to six years with no recurrence. Patient interviews revealed that 72 to 80 percent considered their results as excellent or good. Incontinence or persistent constipation caused the remaining patients to consider their results fair or poor, despite anatomic correction of the prolapse. Abdominal proctopexy and sigmoid resection was more likely to result in improvement of continence than was perineal rectosigmoidectomy.

Ileal pouch vaginal fistulas: Incidence, etiology, and management

Some of the initial problems associated with the ileonal reservoir have been solved. In their place, other complications have been recognized. Among these, the ileal pouch vaginal fistula stands out as a recently recognized difficult management problem. This multicenter study was undertaken to gain insight into the causes for, and treatment of, pouch vaginal fistulas. Cases were gathered from 11 surgical practices, throughout North America, in which the ileoanal reservoir procedure is frequently performed. Overall, 304 females had undergone ileoanal reservoir procedures by these surgical groups. Twenty-one patients developed 22 pouch vaginal fistulas for an overall incidence of 6.9 percent. Five additional patients with pouch vaginal fistulas, whose restorative proctocolectomies were done elsewhere, were referred to these surgeons for treatment. The courses of these 26 patients form the basis of this report. This study details the risk factors which predispose to the development of a pouch vaginal fistula, as well as the various treatment options available.

Modern management of hemorrhoids.

Hemorrhoids require therapy only when they cause symptoms. Early symptoms troubling the patient only occasionally are readily managed by dietary measures that increase the intake of fluids and fiber, such as bran, often supplemented by hydrophilic bulk-forming colloids, so that a bulky, soft stool is produced regularly. Rubber band ligation is the treatment of choice for small or moderate sized hemorrhoids with minimal prolapse, whether or not they bleed. Such bands should be applied to the mucosa at the anorectal junction and not directly to the hemorrhoidal tissue. Patients with large prolapsing or acutely thrombosed hemorrhoids are best managed by a closed type of hemorrhoidectomy. This technique is effective and safe and has great advantage with rapid healing and minimal postoperative care, which provides the patient with the maximum comfort. Complications are few and, in particular, anal stenosis or stricture is rare. Hemorrhoids occurring in association with other conditions require specific treatment only if they are responsible for symptoms in their own right, distinct from the associated condition. Other treatments discussed are effective but have particular disadvantages that make them unsuitable for routine use. Moreover, they offer no advances on the treatment regimens proposed.

Restorative Proctocolectomy with Ileal Reservoir and Ileoanal Anastomosis for Ulcerative Colitis and Familial Polyposis

Our experience with the technique of restorative proctocolectomy utilizing a rectal mucosectomy, total colectomy, and ileal reservoir with ileoanal anastomosis in 56 patients with ulcerative colitis o

The parks S ileal pouch and anal anastomosis after colectomy and mucosal proctectomy

Attention to detail is crucial to the success of the operation described. Surgeons contemplating performing it should first be experts in pelvic surgery and are advised to personally observe and participate in the procedure performed by surgeons currently experienced in this technique.

The presence of insulin-degrading enzyme in human ileal and colonic mucosal cells.

The aim of this research is to characterize the presence of insulin‐degrading enzyme in human colon and ileal mucosal cells. Biochemical studies, including the activity‐pH profiles, the effects of enzyme inhibitors, immunoprecipitation and western blots, were conducted.

Tube decompression of the dilated colon.

With the technique described herein, decompression of a massively dilated colon is effectively accomplished, allowing resection to proceed safely. This method of decompression has allowed us to perform colonic resection in all patients with toxic megacolon seen in recent years. It is desirable to remove the infected and inflamed colon in such a circumstance. We have not resorted to blowhole colostomies in cases of toxic megacolon, as this leaves the colon, which is the septic source, within the abdominal cavity. This technique has also been used successfully to expedite subtotal colectomy and ileosigmoid anastomosis in patients with obstructing lesions of the left side. It allows colonic decompression and on-table bowel preparation by irrigation with antiseptics such as povidone-iodine (Betadine).

Surgical options in ulcerative colitis

Five operative options are now available for treatment of ulcerative colitis: (1) proctocolectomy with ileostomy, (2) abdominal colectomy with ileostomy and retention of the rectum, (3) abdominal colectomy with ileorectal anastomosis, (4) proctocolectomy with creation of a continent stoma or conversion of a standard ileostomy after proctocolectomy to a continent stoma, and (5) restorative proctocolectomy. Each procedure has advantages and disadvantages. With careful assessment, the specific needs of each patient can best be met. In many cases a permanent stoma can be avoided. The newer procedures have not been used long enough for long-term effects to be known, and they must be offered with reservation and then only to well-informed, stable, and relatively fit and cooperative patients.
