    Notes: Abstract A study was undertaken to assess the incidence of inflammation and dysplasia in retained mucosa after double-stapled ileoanal reservoir (IAR) for mucosal ulcerative colitis (MUC). Between September 1988 and February 1992, 56 patients with MUC underwent an IAR. Forty-five patients had a double-stapled IAR (DS-IAR), seven patients had a transanal pursestring stapled IAR (PS-IAR), and four patients had a PS-IAR with mucosectomy. Distal donuts obtained from the stapled IAR were submitted for pathologic review in 55 patients. Nine patients had only small bowel, connective tissue, and/or muscle noted on review. Mucosa was qualified as squamous epithelium (SE), transitional epithelium (TE), or columnar epithelium (CE). All samples were examined for evidence of inflammation and dysplasia. Four patients had SE only, one patient had TE, and 18 had CE. In addition, three patients had SE and CE, seven patients had SE and TE, two patients had CE and TE, and nine patients had all three types. The distance from the dentate line to the anastomosis ranged from 0 to 2.5 cm (mean, 1 cm). In 19 patients (35 percent), the distal donut revealed MUC. Of these 19 patients, six had persistent MUC (43 percent) at the time of subsequent biopsy. An additional four patients had MUC evident on follow-up biopsy but not on distal donuts; two of these four patients had no mucosa in their distal donuts. Only one of the patients with evidence of MUC on donuts and/or biopsy experienced any symptoms referable to active MUC (1.8 percent). None of the specimens examined had any evidence of dysplasia. In 31 patients, no MUC was present in the initial donuts or follow-up biopsies. Although the double-stapled technique appears safe, periodic monitoring is suggested.

    Notes: Abstract PURPOSE: Impairment of sphincter function in patients who undergo ileoanal reservoir is usually most severe immediately after ileostomy closure. Therefore, a prospective, randomized trial was undertaken to assess the potential value of preileostomy closure sphincter-strengthening exercises to improve early functional outcome. METHODS: Patients were randomized either to a control group (Group 1) or to undergo a five-week pelvic floor exercise program (Group 2). An incontinence score from 0 to 20 was used to clinically assess the functional results. Anorectal manometric assessment included: highpressure zone length, mean resting pressure, highest resting pressure, mean squeezing pressure, and highest squeezing pressure. The paired t-test was used to compare the functional results preoperatively and at the time of ileostomy closure. This time corresponded to the conclusion of the exercise program or the equivalent time period for the control group. RESULTS: Twenty-six patients who underwent double-stapled ileoanal reservoir between July 1991 and June 1992 were studied. They included 16 males and 10 females with a mean age of 38 (range, 17–69) years. When both evaluations were compared, the mean incontinence score decreased from 0.2 to 2.8 (Δ=2.6) in Group 1 and from 0.2 to 2.0 (Δ = 1.8) in Group 2 (P=0.07). None of the changes between the preoperative and postoperative clinical and physiologic evaluations were statistically significant (P〉0.05). CONCLUSION: Sphincter-strengthening exercises before ileostomy closure did not minimize the transient impairment of functional results.

    Notes: Abstract PURPOSE: This study was undertaken to postoperatively assess the progression of anal sphincter function and clinical outcome in patients ≥50 years old (Group I) compared with those 〈50 years old (Group II). METHODS: Clinical data were assessed after ileostomy closure by a questionnaire. These data were compiled to obtain an incontinence score, which ranged from 0 (perfect continence) to 20 (total incontinence). Anorectal manometry was performed preoperatively (MN1) and postoperatively, before (MN2) and after (MN3) ileostomy closure. Wilcoxon and paired t-test were used to compare the clinical and functional results, respectively. RESULTS: Group I consisted of 22 patients (mean age, 56 years) and Group II, 50 patients (mean age, 32 years). No differences were found relative to either preoperative pressures or clinical outcome. However, both the mean and high resting pressures were significantly lower in Group I at the MN2 examination. CONCLUSION: The effect on anal sphincters of ileoanal reservoir in patients over the age of 50 years is similar to that noted in younger patients. Transient impairment of internal anal sphincter function observed after ileoanal reservoir is more severe in older patients (P=0.01). However, as in younger patients, it does completely recover after ileostomy closure.

    Notes: Abstract The aim of this study was to prospectively assess the impact of laparoscopy upon the outcome of total abdominal colectomy (TAC). Specifically, patients underwent standard laparotomy with TAC and ileoproctostomy (TAC + IP), TAC and ileoanal reservoir (TAC + IAR), laparoscopically assisted TAC + IP (L-TAC + IP), or laparoscopically assisted TAC + IAR (L-TAC + IAR). Parameters studied included the length of surgery, length of ileus, length of hospitalization, morbidity, and mortality. Five patients underwent standard TAC (Group I), and five underwent L-TAC (Group II). Group I consisted of five patients of a mean age of 32 (range, 24–51) years who had mucosal ulcerative colitis (n=1), familial adenomatous polyposis (n=3), or colonic inertia (n=1). Group II consisted of five patients of a mean age of 33 (range, 17–43) years who had mucosal ulcerative colitis (n=1), familial adenomatous polyposis (n=3), or colonic inertia (n=1). This preliminary prospective study indicates that laparoscopically assisted TAC is feasible. L-TAC resulted in a slightly longer length of ileus and length of hospitalization; these differences were not statistically significant. Moreover, the length of time required for the laparoscopic procedures was 35 percent longer than for the open procedures. Although these results may improve as more cases are performed, dramatic differences in rates of postoperative recovery have not yet been realized. In conclusion, L-TAC, while technically feasible, dose not appear to offer any immediately recognizable benefits to the patient as compared with standard laparotomy.

    Dysplasia and cancer complicating strictures in ulcerative colitis (1990)

    Notes: Abstract Previous studies have found a widely variable prevalence of dysplasia and cancer in colonic strictures in patients with ulcerative colitis. Consequently, therapeutic recommendations are conflicting. To better assess the prevalence, we reviewed the clinical and pathological findings in all 27 patients with ulcerative colitis complicated by stricture who were entered into our Inflammatory Bowel Disease Registry. A true stricture was defined as a persistant localized narrowing of the colon found on air-contrast barium enema or on colonoscopy. Upon careful review, 12 of 27 patients were found to have transient colonic spasm, not a stricture, and were excluded. The remaining 15 patients with true strictures represented 3.2% of all ulcerative colitis patients in the registry. Strictures were identified at 13.3± 9.9 years following the diagnosis of ulcerative colitis. Eleven patients had multiple strictures that were principally located in the left colon. Of the 15 patients, 11 had dysplasia and two had cancer found on colonoscopic biopsy. Ultimately, six patients had carcinoma found at colonoscopy or colectomy (three modified Dukes' stage A, one stage B, and two stage D). All cancers were at the site of a stricture. These findings indicate that a true colonic stricture in ulcerative colitis is frequently associated with dysplasia and cancer, which can be diagnosed with colonoscopic biopsy. A stricture should be considered a strong risk factor for cancer, requiring intensive colonscopic surveillance. If dysplasia is discovered, or if the stricture cannot be adequately biopsied, consideration should be given to total colectomy.

    Notes: Abstract Objectives: Oral epithelial dysplasia (OED) is a histopathologic diagnosis associated with an increased risk of oral cancer. The paper explores the relationship between OED risk and food group intake. Methods: In this case–control study, incident cases of OED were identified through two oral pathology laboratories. Controls, pair-matched 1:1 to cases on age ( ± 5 years), gender, appointment date ( ± 1 year), and surgeon, were identified through the office in which the respective case was biopsied. Exposure data were obtained via a telephone interview and mailed food-frequency questionnaire. cConditional logistic regression was used to obtain odds ratio point estimates. Results: Based upon 87 matched pairs – and after controlling for smoking, drinking, and other potential covariates–there was an apparent inverse relationship between OED risk and the consumption of fruits and vegetables, with the intake of these foods being associated with a strong attenuating effect among smokers. OED risk decreased with increased poultry consumption, but increased modestly with bread/cereal and dairy food intake. Conclusions: This investigation provides evidence that some aspects of diet may be associated with the risk of OED. It also suggests that in oral carcinogenesis the role of diet is not simply one of a late effect.

    Notes: Prostatic intraepithelial neoplasia (PIN) represents the putative precancerous end of the morphologic continuum of cellular proliferations within prostatic ducts, ductules an acini. Two grades of PIN are identified (low grade and high grade), and high grade PIN is considered to be a precursor to invasive carcinoma. The continuum which culminates in high grade PIN and early invasive cancer is characterized by basal cell layer disruption, basement membrane disruption, progressive loss of secretory differentiation markers, increasing nuclear and nucleolar abnormalities, increasing proliferative potential, and increasing variation in DNA content (aneuploidy). Clinical studies suggest that PIN predates carcinoma by ten years or more, with low grade PIN first emerging in men in the third decade of life. The clinical importance of recognizing PIN is based on its strong association with carcinoma; its identification in biopsy specimens of the prostate warrants further search for concurrent invasive carcinoma. © 1992 Wiley-Liss, Inc.

    Notes: Non-invasive transitional cell carcinoma (TCC) occurs as two distinct growth patterns, papillary and non-papillary (flat), which display significant differences in biologic potential. Papillary carcinoma usually presents as a low-grade lesion which frequently recurs multiple times prior to invasion; conversely, non-papillary (flat) carcinoma in situ is usually high-grade at presentation (carcinoma in situ) and frequently associated with invasion. These lesions may occur together, although papillary cancer is more easily visualized cystoscopically due to its exophytic growth; flat carcinoma in situ is often vystoscopically invisible.This report reviews existing data concerning the prognostic value of pathologic grading and staging of non-invasive and early invasive TCC. Emphasis is placed on those studies reporting surgical treatment rather than other forms of treatment. © 1992 Wiley-Liss, Inc.
