Fecal incontinence: a practical approach to evaluation and treatment

Fecal incontinence is a common problem and can have a major impact on the quality of life of those affected. Various disease processes affecting stool consistency, rectal sensitivity, or the anal sphincters can cause fecal incontinence. Obstetric trauma is now known to be a major cause of sphincter dysfunction. The evaluation of the patient with incontinence helps to determine the choice of therapy-medical or surgical. The two most important tests are anorectal manometry, which provides information on sphincter pressures, and rectal sensation, and anal endosonography, which is currently the test of choice for defining the anatomy of the anal sphincters. The choice of therapy depends on the etiology of incontinence, the anatomy of the sphincters, and also on the effect of incontinence on the quality of life of the patient. Control of diarrhea, regardless of the cause, should be attempted first. Biofeedback therapy is effective in the majority of patients and is particularly attractive because it is safe and well tolerated. Surgery is offered when medical therapy is unsuccessful or when the etiology is thought to respond best to surgery, such as in postobstetric trauma. Sphincter repair, for treatment of selective sphincter defects, is the best surgical option. Neoanal sphincters and implanted artificial sphincters are far less attractive because of technical difficulties and low success rate.

Alcohol control and injury death in Alaska native communities: wet, damp and dry under Alaska's local option law

OBJECTIVE

This article tests whether different forms of community-level alcohol control significantly affect injury deaths in a population with extremely high injury mortality.

METHOD

The 1981 Alaska local option law provides a natural experiment for studying how implementation of community level controls may be associated with changes in injury deaths, most of which are alcohol-related, among Alaska Natives living in small communities. The study compares population and community-specific death rates under different levels of alcohol control for the 97 communities that passed restrictions between 1980 and 1993 with the death rates in the same communities during periods when no restrictions were in place.

RESULTS

Injury death rates were generally lower during periods when alcohol sales, importation or possession were restricted than when no restrictions were in place (wet). More restrictive controls (dry) significantly reduced homicides; less restrictive control options (damp) reduced suicides. Accident and homicide death rates fell, on average, by 74 and 66 per 100,000, respectively, for the 89 communities that banned sale and importation or possession. A control group of 61 small communities that did not change control status under the law showed no significant changes over time in accident or homicide death rates.

CONCLUSIONS

The changes in accidental and homicide death rates are statistically significant, although these reduced rates remain 2.5 to 7 times national death rates. The isolated nature of Alaskan villages may explain why alcohol control has more effect in Alaska than has been found in studies of Native Americans living in other states.

Long-term functional outcome and quality of life after stapled restorative proctocolectomy

OBJECTIVE

To evaluate prospectively long-term quality of life and functional outcome after restorative proctocolectomy (RPC) with ileal pouch-anal anastomosis, and to evaluate and validate a novel quality-of-life indicator in this group of patients.

SUMMARY BACKGROUND DATA

Restorative proctocolectomy with ileal pouch-anal anastomosis is now the preferred option when total proctocolectomy is required for ulcerative colitis or familial adenomatous polyposis, but long-term data on functional outcome and quality of life after the procedure are lacking.

METHODS

Patients (n = 977) who underwent RPC with stapled anastomosis for colitis or polyposis coli and who were followed for > or =12 months were included. Quality of life, fecal incontinence, and satisfaction with surgery were prospectively evaluated by structured interview or questionnaire for 1 to 12 years after surgery (median 5.0). Quality of life was scored using the Cleveland Global Quality of Life (CGQL) instrument (Fazio Score). This is a novel score developed over the past 15 years by the senior author. Quality of life was also evaluated in a subgroup of patients with the Short Form 36 (SF-36). The CGQL was validated by determining its reliability, responsiveness, and validity as well as its correlation with the SF-36 score.

RESULTS

Postoperative quality of life as measured by SF-36 was excellent and compared well with published norms for the general U.S. population. The CGQL was found to be reliable, responsive, and valid, and there was a high correlation with the SF-36 scores. Using the CGQL, quality of life was shown to increase after the first 2 years after surgery, and there was no deterioration thereafter. The prevalence of perfect continence increased from 75.5% before surgery to 82.4% after surgery, and although this deteriorated somewhat >2 years after surgery, it was no worse than preoperative values. Ninety-eight percent of patients would recommend the surgery to others.

CONCLUSIONS

Long-term quality of life after ileal pouch surgery is excellent and the level of continence is satisfactory. This surgery is an excellent long-term option in patients requiring total proctocolectomy. The CGQL is a simple, valid, and reliable measure of quality of life after pelvic pouch surgery and may well be applicable in many other clinical conditions.

Strictureplasty is an effective option in the operative management of duodenal Crohn's disease

INTRODUCTION

Duodenal Crohn's disease requiring surgery has traditionally been managed with a bypass procedure. We compared our experience with duodenal strictureplasty with this traditional approach.

METHODS

Records of patients operated on for duodenal Crohn's disease since 1980 were retrospectively reviewed. Patients having strictureplasty or bypass were compared with regard to demographics, indications, complications, and outcome.

RESULTS

Since 1980, 34 patients were operated on for duodenal Crohn's disease. Mean age was 38.9 (range, 16-68) years, and 20 of 34 patients were females, with no significant differences between operative groups. Obstruction was the presenting symptom in 33 of 34 patients, and all had strictures. The basis for diagnosis of duodenal Crohn's disease was macroscopic appearance and the presence of Crohn's elsewhere in 29 of 34 patients, with only 5 of 34 having either duodenal or contiguous antral granulomas. Thirty-seven strictures were present in the 34 patients; 24 were in the proximal duodenum (8 strictureplasty, 16 bypass), 9 were in the midduodenum (4 strictureplasty, 5 bypass), and 4 were in the distal duodenum (3 strictureplasty, 1 bypass). Bypass was performed in 21 patients, with two operative complications, and at a mean follow-up of 8 years, 1 of 21 patients required reoperation for recurrent disease. Strictureplasty was performed in 13 patients, with two operative complication, and at a mean follow-up of 3.6 years, 1 patient required reoperation for recurrence also. Vagotomy was performed in 16 of 21 bypasses and 7 of 13 strictureplasties.

CONCLUSIONS

Although follow-up is shorter, strictureplasty is a safe and effective operation for duodenal Crohn's disease and should be considered when feasible.

What happens to a pelvic pouch when a fistula develops?

PURPOSE

The aim of this article is to determine the outcome of the pelvic pouch after the occurrence of a fistula.

MATERIALS AND METHODS

From 1983 to 1995, 1,040 pelvic pouch surgeries were done at our institution. We reviewed the records of all patients with pouch-related fistulas. Data were collected from chart reviews and our pouch registry.

RESULTS

Among 59 patients (22 males) with fistulas, mean age was 33 (range, 19-57) years. Preoperative diagnosis was mucosal ulcerative colitis (n = 52), indeterminate colitis (n = 6), and familial polyposis (n = 1). Site of fistulas included pouch/vaginal (n = 24), pouch/ cutaneous (n = 11), pouch/perineal (n = 16), and pouch/ presacral (n = 8). Postoperative diagnosis was mucosal ulcerative colitis (n = 40), Crohn's disease (n = 14), indeterminate colitis (n = 4), and familial polyposis (n = 1). One hundred eleven (range, 1-7) surgeries for treatment were performed. At a mean follow-up of 26 (range, 1-121) months, 19 pouches (32 percent) had been excised, 34 patients had functioning pouches and no fistula, 5 patients had a closed fistula but refused ileostomy closure, and 1-patient had died of unrelated causes (but the fistula was closed). Pouch type and preoperative diagnosis did not statistically affect pouch failure rates (P = 0.43 and 0.10. respectively).

CONCLUSION

Successful treatment of fistula from a pelvic pouch can be achieved in more than 60 percent of patients. However, multiple procedures may be needed for a successful outcome. Ultimately, 32 percent had their pouches excised.

Colonoscopy--how difficult, how painful?

Colonoscopy is sometimes painful for the patient and often difficult for the endoscopist, but it is hard to predict how difficult or painful the examination will be. The purpose of this study was to identify factors that influence difficulty and pain during colonoscopy. Some 1,284 consecutive patients undergoing office colonoscopy by three endoscopists were prospectively studied. A standard questionnaire was completed by the nursing staff, who assessed the degree of difficulty and pain associated with each exam on a four-point scale. There were 682 men and 551 women (sex not recorded in 51). There was no pain in 27%, mild pain in 39%, moderate pain in 25%, and severe pain in 9%. There was no difficulty in 25%, mild difficulty in 33%, moderate difficulty in 28%, and severe difficulty in 14%. Colonoscopy was significantly easier (P < 0.001, chi square) and less painful (P < 0.001, chi square) in patients after sigmoidectomy. It was more painful after hysterectomy (P < 0.05, chi square) and more difficult and painful in women than in men (P < 0.01, chi square). There were significant differences between endoscopists in the assessment of pain associated with colonoscopy. Most colonoscopies are associated with little or no pain (66%) and are easy or only mildly difficult to perform (58%). Patients who have had sigmoid resection are especially easy and painless to examine while women, especially after hysterectomy, are at higher risk of having a painful experience. Colonoscopy technique can influence the amount of pain experienced by the patient.
