Laparoscopic-assisted vs. open ileal pouch-anal anastomosis: functional outcome in a case-matched series.

PURPOSE: Functional outcomes in laparoscopic-assisted ileal pouch-anal anastomosis have been incompletely studied. More than one-year follow-up has rarely been reported in these patients. This study was designed to assess operative, functional, and quality of life outcomes in patients with ulcerative colitis or familial adenomatous polyposis a minimum of one year after. METHODS: Thirty-three laparoscopic-assisted ileal pouch-anal anastomosis and 33 open ileal pouch-anal anastomosis patients, with a median of 13 months and minimum of 12 months follow-up, were identified from a prospective, laparoscopic database. Functional outcome was prospectively assessed by using a standardized survey. These cohorts were matched by individual patient for year of surgery, age, gender, body mass index, and indication. RESULTS: Median age was 27 years (open) and 28 years (laparoscopic). There were 27 females and 6 males in each group. All operations occurred between 1999 and 2001. Median body mass index was 22.3 (open) and 21.7 (laparoscopic) groups. There were no significant differences in diagnosis, use of diversion, and anastomotic technique. Postoperative morbidity occurred in 6 percent of the laparoscopic cases and 12 percent of the open cases. Functional outcome after a minimum of one year revealed equivalent median day and median nocturnal number of stools of six to seven and one to two respectively. Consistency of stool, medication usage, and continence were no different between groups. Daytime and nocturnal incontinence was similar. Quality of life in regard to social, home life, family, travel, sports, recreation, and sex life were equivalent. CONCLUSIONS: The function and quality of life outcomes for patients undergoing laparoscopic-assisted ileal pouch-anal anastomosis seem to be equivalent to our open experience. Laparoscopic-assisted ileal pouch-anal anastomosis offers selected patients a safe, feasible, and durable alternative.

Hartmann's reversal is associated with high postoperative adverse events.

PURPOSE: The aim of this study was to ascertain the preva lence and pattern of surgical and medical adverse events in patients undergoing Hartmann's reversal for diverticular dis ease. A comparison of postoperative outcomes is made be tween Hartmann's reversal and primary resection and anas tomosis. METHODS: Data were collected from patients who underwent successful Hartmann's reversal (Group 1 n=121) and primary resection and anastomosis (Group 2 n=731) for diverticular disease in a single center from January 1981 to May 2003. Multivariate logistic regression was used to compare early postoperative mortality, medical and surgical complications and readmission rates between the two groups. RESULTS: Hartmann's reversal was associ ated with a higher prevalence of surgical or medical com plications compared with primary resection and anastomo sis (43.8 percent and 9.1 percent for Hartmann's reversal vs. 26.0 percent and 4.8 percent for primary resection and anastomosis). There was no difference in the readmissior rates (7.2 percent vs. 7.6 percent, respectively, P = 0.88) or early postoperative mortality (1.7 percent vs. 0.7 percent, P = 0.25) between Hartmann's reversal and primary resection and anastomosis. The need for reoperation, prolonged ileus respiratory tract infections, and renal failure were more common adverse events in the Hartmann's reversal group (P < 0.01). Having controlled for the number of comorbid conditions, extent of diverticular disease, severity of peri toneal contamination (Mannheim Peritonitis Index), and op erative urgency, patients who underwent Hartmann's rever sal were 2.1 times more likely to have adverse surgical events during their postoperative period (95 percent confidence interval for odds ratio = 1.3-3.3). CONCLUSIONS: Hartmann's reversal is a complex surgical procedure that is associated with a high prevalence of postoperative adverse events in comparison with primary resection and anastomosis. To minimize the prevalence of such adverse events, patients who undergo Hartmann's reversal need careful preoperative evaluation and close monitoring in their postoperative period.

Quality of life after ileal pouch-anal anastomosis and ileorectal anastomosis in patients with familial adenomatous polyposis.

PURPOSE: Differences in conventional outcomes such as functional results and the rate of complications have caused a controversy about whether the ileal pouch anal anastomosis or the ileorectal anastomosis is the preferred surgical treatment for patients with familial adenomatous polyposis. We therefore sought to ascertain not only the surgical results but also the perceptions of patients about their outcomes. METHODS: Between 1981 and 1998, 152 patients at our institution had an ileal pouch-anal anastomosis and 32 patients had an ileorectal anastomosis for familial adenomatous polyposis. Of these 184 patients, 173 were sent a study-specific quality-of-life questionnaire and the Short Form 36 health survey to determine their health-related quality of life. RESULTS: Ninety-four ileal pouch patients and 21 ileorectal patients returned the surveys. No difference was found in early postoperative complications, 5-year probability for complications, or functional results after either procedure. On the Short Form 36 health survey, the ileorectal patients had a lower mental health summary score compared with that of the ileal pouch patients but a similar physical health summary score. The study-specific questionnaire found both groups to have a comparable quality of life. CONCLUSION: Because ileal pouch-anal anastomosis has the advantage of removing as much at-risk tissue as possible with similar functional results and better mental health, it may be considered the preferred operation for most patients with familial adenomatous polyposis.

The efficacy of a nerve stimulator (Cavermap) to enhance autonomic nerve identification and confirm nerve preservation during total mesorectal excision.

PURPOSE: Sexual dysfunction after total mesorectal excision may be caused by injury to the autonomic nerves. During surgery, nerve identification is not always achieved, and, to date, there has been no method to objectively confirm nerve preservation. The aim of this study was to assess the efficacy of a nerve-stimulating device (CaverMap) to assist in the intraoperative identification of the autonomic nerves during total mesorectal excision, and objectively confirm nerve preservation after proctectomy is completed. PATIENTS AND METHODS: Sexually active consecutive male patients undergoing total mesorectal excision were prospectively enrolled in this study. During pelvic dissection, the surgeon attempted to localize the hypogastric and cavernous nerves. CaverMap was used to confirm these findings and to facilitate the identification in cases of uncertainty. At the completion of proctectomy, the nerves were restimulated to ensure preservation. Factors that could affect the surgeon's ability to localize the nerves and CaverMap to confirm this were evaluated. RESULTS: Twenty-nine male patients with a median age of 58 years were enrolled in this study. An attempt to visualize the hypogastric nerves during dissection was made in 26 patients; the surgeon was able to identify the nerves in 19 (73 percent) patients. CaverMap successfully identified the nerves in six of the seven remaining patients, and failed to identify them in only one case. An attempt to localize the cavernous nerves during dissection was made in 13 patients, of which localization was successful in 8 (61.5 percent) patients. CaverMap improved the identification rate in four of the remaining five patients. After proctectomy, CaverMap successfully confirmed the preservation of both hypogastric and cavernous nerves in 27 of 29 (93 percent) patients. A history of previous surgery statistically correlated with failure to identify the hypogastric nerves by the surgeon (P = 0.005). There were no adverse events related to use of the device. CONCLUSION: CaverMap may be a useful tool to facilitate identification of the pelvic autonomic nerves during total mesorectal excision and to objectively confirm nerve preservation.

Increased experience and surgical technique lead to improved outcome after ileal pouch-anal anastomosis: a population-based study.

PURPOSE: This study was designed to determine whether changes in length of stay and 30-day readmission, reoperation, and excision rates for the ileal pouch-anal anastomosis occurred over time and with changes in surgical technique and hospital volume. METHODS: Using three population-based administrative databases, data on all ileal pouch-anal anastomoses performed in the province of Ontario between January 1992 and June 1998 were obtained. The effect of age, gender, stage of the procedure, year of surgery, and hospital volume were examined for their effect on length of stay and readmission, reoperation, and excision rates. RESULTS: There were 1,285 ileal pouch-anal anastomoses performed in 58 hospitals. There was a significant decrease in length of stay and reoperation and excision rates but a concommitant increase in readmission rate during the study period. Patients younger than aged 40 years had a significantly lower length of stay and excision rate. Patients who had a two-stage procedure had a shorter length of stay, readmission, and reoperative rate compared with those having a three-stage procedure. Hospital volume was a significant predictor of need for reoperation and excision with both low-volume and medium-volume hospitals having significantly higher rates than high-volume hospitals. CONCLUSIONS: Outcome after ileal pouch-anal anastomosis has improved. It is significantly better in patients younger than aged 40 years, having a two-stage procedure, and where surgery is performed at high-volume hospitals. It is likely that both modifications in surgical technique and surgical experience have led to improvements in clinical outcome after ileal pouch-anal anastomosis.

Sacral osteomyelitis after ileal pouch-anal anastomosis: report of four cases.

PURPOSE: This study describes an institutional experience with sacral osteomyelitis after proctocolectomy and ileal pouch-anal anastomosis. METHODS: A total of 2,375 patients underwent ileal pouch-anal anastomosis at the Mayo Clinic between January 1981 and January 2002. In addition, we have served as a tertiary referral base for patients with complications after ileal pouch-anal anastomosis performed at other institutions. Review of our ileal pouch-anal anastomosis prospective database and directed search of the central pathology, microbiology, radiology, and surgical records at the Mayo Clinic was performed using these keywords: osteomyelitis, ileal pouch-anal anastomosis, inflammatory bowel disease, chronic ulcerative colitis, and Crohn's disease. RESULTS: Two of 2,375 patients (0.08 percent) with ileal pouch-anal anastomosis performed at our institution have had sacral osteomyelitis. In addition, two patients have been referred for continuing care after construction of an ileal pouch-anal anastomosis and diagnosis of sacral osteomyelitis at another institution. Two of the four patients maintained normal pouch function after sacral debridement and a period of fecal stream diversion. One patient remains diverted with resolved sacral osteomyelitis after debridement. The last patient died from squamous-cell cancer involving the sacrum. CONCLUSIONS: Sacral osteomyelitis is a rare and heretofore unreported complication of ileal pouch-anal anastomosis. Conservative measures using antibiotics alone proved unsuccessful, and delaying definitive management may have contributed to the degeneration of a chronic sacral abscess into squamous-cell cancer. With more aggressive treatment comprising sacral debridement, long-term antibiotics, and fecal diversion, pouch function can potentially be preserved.

Impact of surgery on the development of duodenal cancer in patients with familial adenomatous polyposis.

PURPOSE: Precancerous duodenal lesions in patients with familial adenomatous polyposis can be detected with duodenoscopy and treatment may prevent the development of cancer. We proposed to determine the frequency, natural history, cumulative risk, and risk factors of the precancerous duodenal lesions in a series of patients diagnosed in northern Italy. METHODS: A prospective, endoscopic, follow-up protocol was performed in 50 patients examined by gastroduodenoscopy at two years of interval or less. The presence and severity of precancerous lesions of the duodenal mucosa were evaluated by Spigelman score. Twenty-five patients (50 percent) had proctocolectomy and ileoanal anastomosis, 15 (30 percent) had colectomy and ileorectal anastomosis, and 5 (10 percent) had proctocolectomy and definitive ileostomy from 0 to 3 years before the admission to the surveillance program. All patients showed more than a thousand adenomas in the colorectal mucosa. No patients with attenuated polyposis were found. RESULTS: At the first endoscopy, duodenal adenomas could be detected in 19 of 50 patients (38 percent), whereas at the end of the follow-up, 43 (86 percent) had duodenal lesions. The final mean Spigelman score increased during the follow-up period (P<0.001 respect to baseline values). No duodenal cancer could be detected. Eleven patients had or developed severe precancerous duodenal lesions (Stage IV) treated with endoscopic or surgical resection. The distribution of patients with Stage IV according to the surgery of the colon was: 2 of 25 treated with ileoanal anastomosis and 8 of 15 with ileorectal anastomosis (P=0.0024, Fisher's exact test). CONCLUSIONS: Patients with familial adenomatous polyposis are at risk of significant neoplasia. The natural history of precancerous lesions might be related to surgical treatment of colorectal neoplasms.

Perineal adenocarcinoma thirty years after proctocolectomy: report of a case.

This report describes an adenocarcinoma arising in the perineum 30 years after two-stage total proctocolectomy for ulcerative colitis. This is one of the longest intervals reported between resection and presentation with cancer and also the only case in which the tumor is clearly free of association with existing bowel. The mass originally presented as a perineal mucocele, an unusual complication of proctocolectomy for ulcerative colitis, and this is the first such mucocele to demonstrate malignant transformation.

Vascular endothelial growth factor and cyclooxygenase-2 are overexpressed in ileal pouch-anal anastomosis.

PURPOSE: Pathophysiology of pouchitis after ileal pouch-anal anastomosis is controversial because of the potential for development of carcinoma. Cyclooxygenase-2-derived prostaglandins may be involved in the inflammatory process and play a role in the pathogenesis of colon cancer. Vascular endothelial growth factor plays a major role in neoangiogenesis and is overexpressed in a number of gastrointestinal malignancies. The goal of this study was to evaluate the expression of cyclooxygenase-2 and vascular endothelial growth factor and to assess neoangiogenesis and epithelial cell proliferation in patients with ileal pouch-anal anastomosis. METHODS: Endoscopic biopsies were obtained from 15 patients with ileal pouch-anal anastomosis without pouchitis (10 biopsies from the ileal pouch and 10 from ileal nonpouch mucosa) and from 15 subjects with irritable bowel syndrome (10 biopsies from normal-appearing ileum and rectum). Cyclooxygenase-1, cyclooxygenase-2, and vascular endothelial growth factor messenger ribonucleic acid expression was determined by reverse transcriptase polymerase chain reaction. Cyclooxygenase-2 and vascular endothelial growth factor protein expression was evaluated by Western blot. Cyclooxygenase-2, vascular endothelial growth factor, CD34 (neoangiogenesis marker), and Ki67 (proliferation marker) mucosal localizations were evaluated by immunohistochemistry. RESULTS: Expression of cyclooxygenase-2 and vascular endothelial growth factor was increased in ileal pouch mucosa compared with ileal nonpouch mucosa, normal ileum, and rectum. Cyclooxygenase-2 and vascular endothelial growth factor immunostaining in ileal pouch mucosa was more intense in the crypt area than in the surface epithelium compared with ileal nonpouch mucosa. CD34 (neoangiogenesis marker) and Ki67 (proliferation marker) expression was increased in ileal pouch mucosa. CONCLUSIONS: Cyclooxygenase-2 and vascular endothelial growth factor are overexpressed in the ileal pouch mucosa. This is associated with increased proliferative activity and neoangiogenesis. Cyclooxygenase-2 and vascular endothelial growth factor overexpression might play a role in the pathogenesis of pouchitis.

Acute ischemic proctitis: report of four cases.

Acute ischemic proctitis is an extremely rare clinical entity. It is mainly described in patients with significant atherosclerotic and cardiac risk factors who present with lower gastrointestinal symptoms in the setting of hemodynamic instability. Previous reports of ischemic proctitis suggest that rectal resection is not necessary in the treatment of this disease. We present four cases of acute ischemic proctitis that required complete proctectomy. All patients had large vessel atherosclerosis with rectal bleeding and sepsis as the presenting signs and symptoms. Three of four patients underwent complete proctectomy as the initial procedure. The fourth patient underwent complete proctectomy five days after the initial intervention. Two of four patients survived and were ultimately discharged from the hospital. A third patient recovered from surgery but ultimately died of respiratory complications. Only the patient who was initially treated by subtotal proctectomy died as the result of the disease. Although ischemic necrosis of the rectum is rare, complete proctectomy may be necessary to save the patient's life.

The type of urinary diversion after radical cystectomy significantly impacts on the patient's quality of life.

BACKGROUND: In this study, we used a previously well-validated survey to assess the impact of different forms of urinary diversion on overall quality of life in patients with bladder cancer. METHODS: A total of 92 patients, having three different forms of urinary diversion after radical cystectomy, completed by mail the SF-36, a validated quality-of-life survey. All patients had local/regional disease at the time of cystectomy and are currently without evidence of disease. Completed surveys were then analyzed into physical (PCS) and mental (MCS) component quality-of-life scores per published protocols. Results were then compared with published age-based norms. RESULTS: A total of 38 men who had cystectomy and ileal neobladder had a mean PCS (+/- SD) of 48.4 (7.8) and a mean MCS of 51.0 (7.4); 16 men and women who had cystectomy and Indiana Pouch had a mean PCS of 48.4 (8.9) and a mean MCS of 55.7 (3.8). None of these results is statistically different from published age- and sex-based population norms. Thirty-eight men who had cystectomy and ileal conduit had a mean PCS of 41.4 (8.5) and a mean MCS of 48.2 (10.7). The PCS is not statistically different from the population-based norm; however, the MCS is significantly decreased from the published norm (P = .01). CONCLUSIONS: Patients with ileal conduits have significantly decreased mental health quality of life whereas patients with continent urinary diversions do not. Therefore, when not medically contraindicated, patients should be offered a continent diversion as the diversion of choice after cystectomy.

Factors associated with nighttime incontinence following ileoanal pullthrough.

Minor nighttime incontinence following colectomy, mucosal proctectomy, and ileoanal pullthrough remains a bothersome and incompletely understood problem. Of 277 ileoanal pullthrough procedures performed at this institution between 1982 and 1989, 38 were performed on patients with polyposis coli syndrome. These 38 polyposis patients were selected to study nighttime incontinence because they represented a select population in which sphincter injury due to technically difficult mucosal stripping was minimized (compared with the difficult and hazardous mucosal stripping in inflamed tissues present in ulcerative colitis). In this series, 12 patients (32%) experienced nighttime incontinence after ileoanal pullthrough; in 9 of the 12 patients, this complication had resolved within 6 months postoperatively. Females had a significantly higher rate of minor nighttime incontinence (57%) than males (17%). Pouch size was significantly smaller in patients with nighttime incontinence (138 mL) than in continent ones (191 mL). Higher stool frequency soon after surgery also correlated with higher incontinence rates. Factors that did not show association with nighttime incontinence in this series were preoperative and postoperative resting and squeeze and sphincter pressures, disease interval, parity, and previous surgery. We conclude that nighttime incontinence is a common complication that occurs even after "technically easy" mucosal proctectomies. Further investigation will almost certainly reveal it to be multifactorial in etiology.

Stapled coloanal anastomosis with reservoir procedure.

A closed-lumen procedure of coloanal anastomosis with a reservoir, performed exclusively with staplers to reduce spillage, is described. This stapling procedure provides three advantages: simplicity, reduction of spillage, and the preservation of sphincteric structures. In 33 procedures performed, 2 (6%) anastomotic leakages and 5 (15%) dilatable stenoses occurred.

Anal sphincter-saving operations for chronic ulcerative colitis.

Three anal sphincter-saving operations--ileorectostomy, ileal pouch-anal anastomosis, and ileal pouch-distal rectal anastomosis--are currently being used in the surgical treatment of chronic ulcerative colitis. All three operations remove the disease, or most of it, and yet they maintain transanal defecation, reasonable fecal continence, and a satisfactory quality of life. All three avoid permanent abdominal ileostomy. Ileorectostomy is the easiest to perform, but it leaves residual disease in the remaining rectum and proximal anal canal that may cause symptoms and that may predispose the patient to cancer. In contrast, ileal pouch-anal anastomosis, although a more technically demanding procedure, totally eradicates the colitis. Its main drawbacks--frequent stooling, nocturnal fecal spotting, and pouchitis--are usually satisfactorily treated with loperamide hydrochloride and metronidazole. Ileal pouch-distal rectal anastomosis is somewhat easier to perform than ileal pouch-anal anastomosis and may result in less nocturnal fecal spotting. Like ileorectostomy, however, the operation leaves residual disease in the distal rectum and proximal anal canal. Considering all of these factors, the ileal pouch-anal operation is preferred today for most patients who require surgery for chronic ulcerative colitis.

Preservation of continence after ileoanal anastomosis by the coordination of ileal pouch and anal canal motor activity.

Nocturnal incontinence may occur after ileoanal anastomosis and may be related to loss of an effective anal canal pressure barrier during sleep; how pressure and contractions in the proximal bowel influence this barrier is unknown. Our aim was to evaluate the relationship between anal canal pressure and contractions and contractile activity of the pouch in continent subjects after ileal pouch-anal anastomosis (IPAA) and of the rectum in normal controls. A fully ambulatory system for 24-hour pressure recording was used. A flexible transducer catheter was introduced endoscopically so that sensors were at 2, 3, 8, 12, 16, and 24 cm from the anal orifice in 12 healthy controls (7 men, 5 women, mean age: 35 years) and 7 fully continent IPAA patients (4 men, 3 women, mean age: 34 years) more than 12 months postoperatively. Twenty-four hour spontaneous motor activity was stored in a 2.5 megabyte (MB) digital portable recorder. Mean anal canal pressure was calculated, and rectal motor complexes and ileal pouch large pressure waves were characterized. During sleep, resting anal canal pressures were similar in the two groups (72 +/- 12 mm Hg in controls versus 66 +/- 9 mm Hg in IPAA patients [mean +/- standard deviation (SD)], p = NS), but anal canal pressure showed cyclic relaxations (periodicity: 95 +/- 11 min in controls, 54 +/- 18 min in IPAA patients, p less than 0.05), during which the mean pressure trough was 15 +/- 4 mm Hg in controls and 14 +/- 5 mm Hg in IPAA patients (p = NS). In the control patients, during sleep, a mean of six rectal motor complexes were identified (range: 3 to 9). In patients with IPAA, during sleep, a mean of eight large pressure waves per hour were identified (range: 2 to 20). Importantly, in both controls and patients, rectal motor complexes or large pressure waves were always accompanied by rapid return of anal canal pressure from trough to basal values and increased contractile activity. We concluded that, in healthy patients and in continent patients after IPAA, motor activity of the rectum and of the ileal pouch was associated with changes in pressure and contractile activity of the anal canal so that rectal- and neorectal-anal canal pressure gradient, and, in turn, fecal continence were preserved.

Stapled ileoanal anastomosis without a temporary ileostomy.

Stapled J-pouch ileoanal operations were performed in 75 patients (35 men, 40 women; 72 with ulcerative colitis, 3 with familial polyposis) without an ileostomy in 68 (43 taking prednisone, 12 emergent surgery, 8 completion proctectomy with ileostomy takedown). The seven primary ileostomies were due to technical difficulties in two patients and toxic colitis in four patients. No patients were lost to follow-up. Of patients followed for more than 1 month, 96% had perfect daytime control, 86% had no nocturnal accidents, and 73% had no nocturnal spotting. Mucosa between the dentate line and the anastomosis averaged 1.1 +/- 1.0 cm, with the anastomosis at, or below, the dentate line in 16 patients, of whom 14 had excellent continence. Stools in 24 hours averaged 6.9 +/- 0.3, of which 1.8 +/- 0.2 were at night. Stool frequency was unrelated to gender, anastomotic distance from the dentate line, or age; however, patients 50 years of age or older had more problems with nocturnal fecal control than those younger than 50 years of age. Anastomotic leaks (four), cuff abscess (one), pouch leaks (two), and pelvic abscesses (three) were treated with drainage in all patients and ileostomy in five. Pouchitis occurred in 31% of patients and responded to oral antibiotic therapy. Acute complications were fewer, functional pouches greater, stool control better, and overall hospitalization shorter (all p < 0.01) than those in our 63 patients with a mucosectomy and handsewn ileoanal anastomosis.
