    Notizen: Abstract Fifteen consecutive patients (nine males and six females) who underwent construction of a double-stapled ileoanal reservoir (DS-IAR) were prospectively evaluated. Mean and maximal resting pressures preoperatively, before ileostomy closure, and at 12 months, were 53 and 84 mm Hg, 39 and 62 mm Hg, and 62 and 81 mm Hg. Mean and maximal squeeze pressures at those same time periods were 96 and 153 mm Hg, 111 and 173 mm Hg, and 95 and 168 mm Hg. There were no significant decreases in either resting or squeeze pressure between preoperative values and those obtained 12 months after surgery. However, the length of the high pressure zone decreased from 3–8 cm preoperatively to 2.3 cm at 12 months. This reflects the sacrifice of the cephalad 1.5 cm of the internal anal sphincter necessary to effect this anastomosis at a mean of 1.4 cm from the dentate line. However, this maneuver did not result in poor continence. Eleven patients whose ileostomies were closed for a mean of 9 months, ranging from 3 to 15 months, were evaluated regarding functional outcome. Only one patient had any incontinence and this patient had incomplete circularstapled tissue rings, which necessitated transanal suture repair of the anastomotic defect. Similarly, three of the four patients who sometimes or rarely use a pad at night had transanal-suture reinforcement. Ten of the 11 patients never wear a pad during the day. No pelvic or perianal sepsis occurred. Stratified squamous epithelium was found in 6 of the 13 distal stapler “donuts” that were examined. In addition, 10 patients underwent biopsy of the tissue immediately caudad to the circular staple line at the time of ileostomy closure; in five, only stratified squamous epithelium was noted. The DS-IAR is associated with excellent objective physiologic and subjective functional results.

    Notizen: Abstract Forty-two of 416 familial adenomatous polyposis (FAP) patients in the FAP registry at the Cleveland Clinic had desmoid tumors. The role of cytotoxic chemotherapy and radiation therapy in the management of these patients was investigated. Eight intra-abdominal desmoid tumors were treated by systemic cytotoxic chemotherapy. Two had complete remission, and one had partial remission. Five patients died as a result of the desmoid tumor or late complications of chemotherapy. Three intra-abdominal desmoids were treated by radiation therapy with no response. Neither cytotoxic chemotherapy nor radiation therapy is recommended as a first-choice treatment for intra-abdominal desmoid tumors in patients with FAP.

    Notizen: 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.

    Notizen: Abstract Forty of 416 patients with familial adenomatous polyposis were noted to have intra-abdominal desmoid tumors, and a subgroup of 16 were treated with noncytotoxic drug therapy. Drugs used were sulindac (14 patients), sulindac plus tamoxifen (3 patients), indomethacin (4 patients), tamoxifen (4 patients), progesterone (DEPO-PROVERA®; Upjohn Co., Kalamazoo, MI) (2 patients), and testolactone (1 patient). Therapy with these drugs for continuous periods of six months or more resulted in three complete and seven partial remissions. When treated patients were compared with untreated patients (n=12), there were significant benefits for the treated group, both in reduction of desmoid size and in improvement of symptoms, despite the inherent selection bias against this. Sulindac was the only drug used in enough patients to permit independent evaluation of its effect, with one complete and seven partial reductions of tumor size. Some patients had a delayed response to sulindac, with tumor shrinkage occurring after an initial period of tumor enlargement. When using sulindac for the treatment of desmoid tumors, this phenomenon should be considered.

    Notizen: 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.

    Notizen: Abstract The authors identified 132 patients who died with a documented diagnosis of familial adenomatous polyposis (FAP). A review of the medical records, autopsy reports, and in-depth discussion with local physicians and well-informed family members was performed. It was impossible, even after the review, to ascertain the exact cause of death in 22 patients. In the remaining patients, the cause of death was as follows: metastatic colorectal carcinoma, 64 patients (58.2 percent), (colon, 49 [44.5 percent], rectal, 15 [13.6 percent]); desmoid tumors, 12 (10.9 percent); periampullary carcinoma, 9 (8.2 percent); brain tumors, 8 (7.3 percent); perioperative mortalities, 5 (4.5 percent); adrenal carcinoma, 1 (0.9 percent); and abdominal carcinomatosis, 1 (0.9 percent). Ten patients died of causes not related to FAP. The major causes of death in 36 patients who underwent prophylactic colectomy were desmoid tumor and periampullary malignancy. This finding underscores the importance of lifelong surveillance and periodic endoscopic evaluation in patients with FAP.

    Notizen: Abstract This study was undertaken to prospectively assess all morbidity and mortality associated with temporary loop ileostomy. Eighty-three consecutive patients of a median age of 45 years required temporary fecal diversion after either ileoanal or low colorectal anastomosis (n=72), for perianal Crohn's disease (n=5), or for other reasons (n=6). All loop ileostomies were supported with a rod, and fecal diversion was maintained for a mean of 10 weeks. To date, 67 patients have had re-establishment of intestinal continuity. Stoma closure was affected through a parastomal incision in 64 patients; in three, a laparotomy was required. The closure was stapled side to side in 49 patients, while a hand-sewn anastomosis was done in the other 18 patients; all skin wounds were left open. The mean length of surgery for ileostomy closure was 56 minutes, and the mean hospital stay was five days. Nine patients (10.8 percent) developed 10 complications, nine of which required hospitalization. Specifically, four patients developed dehydration and electrolyte abnormalities secondary to high stoma output, and two had anastomotic leaks that spontaneously healed following conservative management. One patient developed a superficial wound infection that spontaneously drained itself. One patient developed a partial small bowel obstruction that resolved without surgery after a four-day hospitalization. One stoma retracted after supporting rod removal and prompted premature closure. There was no stomal ischemia, hemorrhage, prolapse, or mortality in this series. Thus, loop ileostomy is a safe way to achieve fecal diversion.

    Notizen: 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.

    Notizen: Abstract A retrospective review of the familial adenomatous polyposis registry at the Cleveland Clinic Foundation revealed an incidence of spontaneous mutation in familial adenomatous polyposis (FAP) of 22 percent of family kindreds. These patients were reviewed retrospectively and compared with the total FAP population followed at The Cleveland Clinic Foundation with respect to the onset of disease, the incidence of carcinoma in the resected colon, and incidence of extracolonic manifestations. Review of the characteristics and presentations of these patients suggested that these individuals may harbor a more severe form of FAP. This may be due, in part, to the delay in diagnosis and, therefore, a higher rate of development of colorectal carcinoma and possibly duodenal adenomas. There is also a demonstrable higher rate of extracolonic manifestations of FAP present in this subset of patients. When selecting the initial type of prophylactic colonic resection the surgeon should bear in mind the increased incidence of extracolonic manifestations of the disease in this group of patients and their potential for complications.

    Notizen: Abstract One hundred forty-eight members of 53 kindreds with familial adenomatous polyposis (FAP) were examined for congenital hypertrophy of the retinal pigment epithelium (CHRPE) and extracolonic manifestations (ECM) to assess the value of CHRPE as a predictive marker for FAP. Based on eye examination results, the families were divided into 2 groups. In a first group of 34 families, all 61 members diagnosed as having polyps and 13 of the 33 patients at risk had 4 or more lesions distributed in both eyes. By contrast, in a second group of 18 families, all 32 polyposis patients and all 18 members at risk had less than 4 lesions. Extracolonic manifestations were present in 26 of 34 families in the first group and in 11 of 18 families in the second group. Data on one family with ambiguous ancestry were reviewed separately. The existence of 4 or more CHRPE lesions distributed in both eyes seems to be a congenital marker for FAP, present in 65.4 percent of families. When present in a family: 1) it is found in all diagnosed patients in that family, 2) can therefore be considered predictive for the development of polyps in other family members who carry the trait, and 3) if confirmed by longer follow-up, may possibly preclude members without the trait from further evaluation and surveillance.
