Results of restorative proctocolectomy in the elderly

Short-Term Outcomes for Restorative and Non-Restorative Proctocolectomy in Older Adults

BACKGROUND

Curative surgery for ulcerative colitis can be subdivided into restorative (with pouch and anastomosis) and non-restorative operations. Restorative surgery in older adults is controversial, due to concerns about surgical risk and long-term functional outcome. The goal of this study is to compare 30-day outcomes for restorative and non-restorative surgery in older adults with ulcerative colitis.

METHODS

Data were obtained from the American College of Surgeons National Surgical Quality Initiative Program from 2012-2018. Patients were included if they were >65 years old and had ulcerative colitis. Restorative and non-restorative surgeries were defined with procedure codes. Patient characteristics and adverse surgical outcomes were compared between restorative and non-restorative surgeries utilizing chi-square tests and Fisher's exact tests. Multivariate logistic regression models were constructed to evaluate the association of restorative versus non-restorative surgery with adverse surgical outcomes while adjusting for potential confounders.

RESULTS

Of 392 total patients, 95 had restorative and 297 had non-restorative surgery. Patients undergoing restorative surgery, compared to non-restorative surgery, were significantly younger (P<0.01), had lower incidences of steroid usage (P<0.001) and higher rates of readmission (P = 0.02). There were no differences in post-operative complications between the groups in both unadjusted analyses and covariate-adjusted regression analysis (P > 0.05).

CONCLUSION

In carefully selected older patients with ulcerative colitis, restorative surgery is associated with increased readmission, but otherwise similar rates of morbidity or mortality compared to non-restorative surgery. Data regarding postoperative functional outcome and quality of life are also needed to help select the most appropriate curative option for older adults.

Ileal pouch-anal anastomosis in the elderly: A systematic review and meta-analysis

AIM

Despite good overall outcomes in most patients undergoing ileal pouch-anal anastomosis (IPAA), there is still hesitation about performing an IPAA in older patients due to the comorbidity burden and concern about incontinence. The aim of this work was to identify short- and long-term outcomes in older patinets undergoing IPAA to determine the perioperative safety and long-term functional success of IPAA in older patients.

METHOD

A literature search was performed for all publications on IPAA in adults aged ≥50 years that reported short- and long-term outcomes. Data extraction included demographics, 30-day outcomes, long-term functional outcomes and pouch failure. Data were further separated by age group (50-65 and ≥65 years). Outcomes were compared between age groups. Study quality and risk of bias was assessed using the Newcastle-Ottawa Scale.

RESULTS

Of 1053 publications reviewed, 13 full papers were included in the analysis. The overall 30-day morbidity and mortality rates were 47.3% and 1.3%, respectively. Thirty-day postoperative rates of small bowel obstruction and pelvic sepsis were 7.6% and 9.9%, respectively. After a median follow-up time of 62 months, rates of pouchitis, incontinence and pouch failure were 13.9%, 17.5% and 7.5%, respectively. There was no statically significant difference in rates of short- or long-term functional outcomes based on age 50-65 versus ≥65 years.

CONCLUSION

Increasing age did not increase the rate of short- or long-term outcomes, including pouch failure. These data suggest that the decision for IPAA construction should not be based on age alone.

The prevalence of chronic peri-pouch sepsis in patients treated for antibiotic-dependent or refractory primary idiopathic pouchitis

AIM

Chronic peri-pouch sepsis (CPPS) may be mistaken for antibiotic-dependent or refractory primary idiopathic pouchitis (ADRP), but requires different treatment such as drainage. The study aimed to identify the prevalence of CPPS in patients thought to have ADRP. The secondary aims were to identify any specific features on pouchoscopy suggesting CPPS and to determine the results of treatment for CPPS.

METHOD

The records of patients who had been treated for ADRP between March 2006 and June 2015 were reviewed retrospectively. Only those with endoscopic evidence of pouch inflammation who had also undergone MRI of the pelvis were included. The findings on pouchoscopy and the outcome of treatment were determined.

RESULTS

Sixty-eight patients (43 men, 63%) were identified with apparent ADRP between March 2006 and June 2015. MRI of the pelvis showed CPPS in 26 (38%). In those with CPPS, the inflammation was more often located in the upper pouch alone (15%) compared with patients without CPPS (0%) (P = 0.0184). Examination under anaesthesia was performed in 13 of those with CPPS. In five a collection was identified and drained; symptoms improved in only one (4%). Eighteen patients (69%) remained on antibiotics and seven (27%) had a defunctioning stoma or underwent pouch excision.

CONCLUSION

In patients thought to have ADRP, 38% had CPPS on MRI. There was no clinically relevant specific feature on pouchoscopy suggestive of CPPS. The possibility of CPPS should be considered early in patients with apparent ADRP and pelvic MRI performed. This might lead to earlier detection of CPPS and appropriate treatment.

Restorative Proctocolectomy in Elderly IBD Patients: A Multicentre Comparative Study on Safety and Efficacy

BACKGROUND AND AIMS

Restorative proctocolectomy in elderly inflammatory bowel disease [ IBD] patients is controversial and limited data are available on the outcomes of surgery. The aim of this study was to evaluate the safety, efficacy, and long-term results of ileal-pouch-anal anastomosis in elderly patients, in a multicentre survey from European referral centres.

METHODS

The International Pouch Database [IPD] combined 101 variables. Patients aged ≥ 65 years were matched on the basis of open versus laparoscopic surgery with a control group of consecutive younger unselected patients with a ratio of 1:2. Statistical analysis was performed using two-tailed t test, chi square and Fisher's exact tests, Kaplan-Meier function, and log-rank tests where appropriate.

RESULTS

In the IPD, 77 patients aged ≥ 65 years [Group A] and 154 control patients [Group B] were identified. Elderly patients had more comorbidities [p = 0.0001], longer disease duration [p = 0.001], less extensive disease [p = 0.006], more previous abdominal operations [p = 0.0006], surgery for cancer or dysplasia more frequently [p = 0.0001], fewer single-stage procedures [p = 0.03], more diversions after ileal pouch-anal anastomosis [IPAA] [p = 0.05], and a higher laparoscopic conversion rate [p = 0.04]. Postoperative complications and pouch failure were similar between the groups, but Group A had more Clavien-Dindo IV-V complications [p = 0.04], and longer length of stay [p = 0.007]. Laparoscopy was associated with a shorter duration of surgery [p = 0.0001], and length of stay [p = 0.0001], and the same complication rate as open surgery.

CONCLUSIONS

Restorative proctocolectomy can be performed in selected elderly patients, but there is a higher risk of postoperative complications and longer length of stay in this group. Laparoscopy is associated with shorter operating time and length of stay.

Functional outcomes following ileal pouch-anal anastomosis (IPAA) in older patients: a systematic review

AIM

Ileal pouch-anal anastomosis (IPAA) is performed in ulcerative colitis or familial adenomatous polyposis with a view to restoration of GI continuity and prevention of permanent faecal diversion. Debate exists as to its safety in older patients. This review aims to assess functional outcomes and safety of restorative proctocolectomy (RPC) in older compared to younger patients.

METHODS

Literature search was performed for age-stratified studies which assessed functional outcomes of IPAA. Twelve papers were included overall. Patients were categorized into 'older' and 'younger' groups. Analysis was split into three separate parts: 1. Age cut-off of 50 ± 5 years (with sensitivity analysis); 2. Age cut-off of 65 ± years; 3. Long-term outcomes (>10 years).

RESULTS

With an age cut-off of 50 years (4327 versus 513 patients), complication rates were comparable with the exception of an increased rate of small-bowel obstruction in the younger patients (p = 0.034). At 1 year, 24-h stool frequency was significantly higher in the older patient group (p < 0.0001). Daytime (p < 0.0001) and night-time (p < 0.0001) incontinence rates were also significantly higher in older patients. Overall, function deteriorated with time across all ages; however, after 10 years, there was no significant difference in incontinence rates between age groups. Dehydration and electrolyte loss was a significant problem in patients over 65 (p < 0.0001). Despite differences in postoperative function, quality of life was comparable between groups; however, only a few studies reported quality of life data.

CONCLUSION

IPAA is safe in older patients, although treating clinicians should bear in mind the increased risk of dehydration. Postoperative function is worse in older patients, but seems to level out with time and does not appear to significantly impact on overall quality of life and patient satisfaction. Assessment for suitability for RPC should not be based on chronological age in isolation. It is imperative that the correct support is given to older patients with worsened postoperative function in order to maintain patient satisfaction and adequate quality of life.

Ileal pouch-anal anastomosis: Points of controversy

Restorative proctocolectomy with ileal pouch-anal anastomosis has become the most commonly used procedure for elective treatment of patients with ulcerative colitis and familial adenomatous polyposis. Since its original description, the procedure has been modified in order to obtain optimal functional results with low morbidity and mortality, and yet provide a cure for the disease. In this review of the literature of restorative proctocolectomy with ileal pouch-anal anastomosis, we discuss these technical modifications, limiting our discussion to the current points of controversy. The current "hot topics" for debate are: indications for ileal pouch-anal or ileo-rectal anastomosis, indications for pouch surgery in the elderly, indeterminate colitis and Crohn's disease, the place of the laparoscopic approach, transanal mucosectomy with hand-sewn anastomosis vs. the double-stapled technique, the use of diverting ileostomy and the issue of the best route for delivery of pregnant women. Longer follow-up of patients and increased knowledge and experience with pouch surgery, coupled with ongoing prospective evaluation of the procedure are required to settle these issues.

Surgical outcomes in the elderly with inflammatory bowel disease are similar to those in the younger population

BACKGROUND

Inflammatory bowel disease (IBD) has a bimodal distribution with approximately 15 % of patients manifesting after age 65. Previous reports suggest an increased risk of surgical complications in the elderly.

AIM

To compare surgical outcomes in elderly IBD patients (≥ 65 years at the time of surgery) to matched younger IBD cohorts.

METHODS

This was a retrospective cohort study at a single academic center of patients who underwent surgery for IBD. Forty-two elderly patients (≥ 65 years) were matched at least 1:1 (median 1:5) to patients in each of three control groups [18-35 years (n = 71); 36-49 years (n = 62); 50-64 years (n = 58)] according to gender, disease type/location, and type of surgery. Postoperative complications were compared. Patient characteristics were used in multivariate risk models. Analysis was performed using ordinary logistic regression.

RESULTS

Twenty ileal or ileocolonic resections, 12 partial or total colectomies, four stricturoplasties, and six laparoscopic partial or total colectomies were performed in the elderly group. The post-operative complication rate was not statistically different between the elderly and younger cohorts (38 % vs. 39 % vs. 40 % vs. 48 % in the 18-35, 36-49, 50-64, and ≥ 65 years groups, respectively, p = 0.26). The only significant risk factors for complication were Charlson comorbidity index (p = 0.0002), preoperative hemoglobin (p = 0.0065), total parenteral nutrition use (p = 0.024), and failed medical therapy (as the indication for surgery) (p = <0.0001).

CONCLUSIONS

The surgical complication rate among elderly and younger IBD patients was similar. Advanced age by itself should not be considered a risk factor for adverse operative outcome.

Pelvic sepsis after IPAA adversely affects function of the pouch and quality of life

BACKGROUND

Pelvic sepsis after IPAA predisposes to pouch failure. There are limited data on long-term pouch function for patients with pelvic sepsis.

OBJECTIVE

The aim of this study was to investigate functional outcomes and quality of life for patients undergoing IPAA who develop pelvic sepsis and preserve their pouch long-term.

DESIGN

This study is based on retrospective analysis of prospectively accrued data.

SETTINGS

This study was conducted at a single-center institution.

PATIENTS

All patients undergoing IPAA from 1983 to 2007 were included.

MAIN OUTCOME MEASURES

The primary outcomes measured were functional outcomes (urgency, incontinence, bowel movements) and quality-of-life (restrictions, energy, happiness) parameters.

RESULTS

Two hundred (6.2%) of 3234 patients developed pelvic septic complications within 3 months of IPAA. In the comparison of complications at the time of IPAA for the 2 groups, patients with pelvic sepsis had higher rates of postoperative hemorrhage (13.5% vs 3.7%, p < 0.001), anastomotic leak (35% vs 3.7%, p < 0.001), wound infection (14% vs 7.4%, p < 0.001), and fistula formation (37% vs 7.1%, p < 0.001). The overall median follow-up was 7 years. Pelvic sepsis was associated with greater pouch failure (19.5% vs 4%, p < 0.001). For patients with follow-up (pelvic sepsis = 144, nonpelvic sepsis = 2677) with a retained pouch, for whom we compared functional outcomes and quality of life, incontinence was worse (never/rare: 69.5% vs 77.8%, p = 0.03). Urgency scores were lower in pelvic sepsis but not statistically significant. The overall Cleveland Global Quality of Life score (and components) in the sepsis group were significantly worse than in the nonsepsis group (0.74 vs 0.79, p < 0.001). Patients who developed sepsis were also less likely to recommend IPAA to others than patients who did not develop pelvic sepsis.

LIMITATIONS

This study was limited by the retrospective analysis and the use of questionnaires.

CONCLUSIONS

Pelvic sepsis after IPAA leads to worse functional outcomes and quality of life even when it does not lead to pouch failure. This finding argues for careful attention to preoperative and intraoperative planning and strategies aimed at reducing this complication after IPAA.

Influence of age at ileoanal pouch creation on long-term changes in functional outcomes

AIM

We reviewed the functional results and quality of life (QOL) of patients who had had an ileoanal pouch (IPAA) for at least 15 years.

METHOD

Retrospective analysis was undertaken of data accrued prospectively into a pouch database since 1983. Patients who had retained an IPAA for at least 15 years were identified. Trends in IPAA function and QOL of the patients were determined over a time-period of 15 years after formation of the IPAA. Data were compared for patients who were < 35, 35-55 and > 55 years of age when the IPAA was formed.

RESULTS

Three hundred and ninety-six of a total of 3276 patients in the database (53% men, median age 36 years and median follow-up 17.1 years) underwent IPAA with at least 15 years of follow-up. The final pathology was ulcerative colitis in 78%; 66.4% of patients had a restorative proctocolectomy, 91.4% underwent temporary diversion, 59% had a J-pouch configuration and 63.1% a stapled anastomosis. The frequency of bowel movements remained the same over the follow-up period. There was an increase in the incidence of incontinence and urgency after 15 years with no significant change in dietary, social, work and sexual restrictions during follow-up. Patients in all three age groups experienced deterioration in pouch function at 15 years of follow up compared with the function at 5 years. The QOL of the patients remained high and stable.

CONCLUSION

There is a deterioration of pouch function after 15 years, irrespective of the age of the patient when the IPAA was formed. Despite this, QOL appears to be high for all patients who retain their pouch.

Ileal pouch-anal anastomosis in elderly patients: is there a difference in morbidity compared with younger patients?

AIM

The aim of this study was to review the recent results of ileal pouch-anal anastomosis (IPAA) in elderly patients compared with younger patients.

METHOD

Retrospective evaluation was carried out based on a prospective Institutional Review Board approved database of patients who underwent IPAA from 2001 to 2008. Patients aged ≥ 65 years were matched with a group of patients aged < 65 years by gender, date of procedure, diagnosis and type of procedure performed. Preoperative and intra-operative data and early postoperative complications were obtained.

RESULTS

Thirty-three patients (22 women), 32 with mucosal ulcerative colitis, were included in each group. The elderly group had a mean age of 68.7 years, body mass index of 27 kg/m², duration of disease of 17.4 years, high American Society of Anesthesiologists (ASA) score and high incidence of comorbid conditions (87.9% had one or more). Dysplasia and carcinoma were the indication for the surgery in more than 50% of patients, followed by refractory disease (24.4%). The matched younger group had a mean age of 36.9 years, body mass index of 25.4 kg/m², shorter duration of disease (8.1 years; P = 0.001), lower ASA score (P = 0.0001) and lower comorbidity (42.4%; P = 0.0002). Operative data were similar for both groups. The elderly group had a higher rate of rehospitalization for dehydration (P = 0.02). Other medical complications (30 vs 27%) and surgical postoperative complications (33 vs 24%) were similar for both groups. The long-term function and complications were comparable for the groups.

CONCLUSION

Elderly patients who underwent IPAA had more comorbid conditions than younger patients. Except for rehospitalization for dehydration, medical and surgical postoperative complications were not different in the two groups.

Ileal reservoir with ileo-anal anastomosis: long-term complications

Coloproctectomy with ileo-anal anastomosis (CP-IAA) has been in use for 30 years. This intervention is the standard technique when surgery is indicated for familial adenomatous polyposis (FAP) and for ulcerative colitis (UC). Although the surgery is safe with mortality of less than 1%, it is associated with a morbidity of 18-70%. We thought a literature review about long-term complications would be enlightening. Pouchitis is the most common complication; it occurs in 70% of patients over 20 years follow-up; small bowel obstruction affects 25% of patients and pelvic sepsis occurs in 20-30% within 10 years. CP-IAA can impact the patient's sexual life due to erectile and ejaculatory dysfunction, dyspareunia, and incontinence of stool during sexual intercourse. Nevertheless, patients with long-standing UC describe an overall improvement in their sexual function after surgery. The failure rate varies from 3.5 to 15%; major causes of failure are sepsis, unrecognized Crohn's disease, and poor functional results. Cases of dysplasia and cancer have been reported in the reservoir, but more particularly when there is retained colonic glandular mucosa. The transitional zone should be monitored whenever there are risk factors for colon neoplasia. The relatively high morbidity of CP-IAA should not overshadow the good functional results of this technique.

The Effect of Pelvic Septic Complications on Function and Quality of Life after Ileal Pouch-Anal Anastomosis: A Single Center Experience

Ileal pouch-anal anastomosis (IPAA) has become the procedure of choice for surgical treatment of intractable ulcerative colitis (UC). Surgical complications occurring in the short-term, like pelvic sepsis, are responsible for pouch dysfunction. We prospectively evaluated 118 patients with IPAA for UC operated on between 1987 and 2002. Follow-up intervals were at 3, 6, and 12 months in the first year, then every year for at least 5 years. Patients answered a questionnaire 1 and 5 years after ileostomy closure. One hundred and seventeen patients completed the early follow-up. Nine patients developed early pelvic sepsis (7.69%); six required pouch salvage procedure. In about 33.3 per cent of cases more than one procedure was necessary. Eighty-eight patients were available for 5-year functional evaluation. Patients developing early sepsis (n = 9) showed worse long-term functional results compared with the remaining study population (n = 79): stool frequency; night evacuation; perfect day/night continence; discrimination; antidiarrhoeals need; pad usage; and sexual restriction were significantly different ( P < 0.05). Quality of life and satisfaction after surgery were good in all patients. This observation did not correlate with function. Eighty-eight and 97 per cent would undergo IPAA again and would recommend it to others respectively, in septic group and controls. Functional outcome after IPAA may be influenced by early septic complications. Overall quality of life and satisfaction with surgery are comparable with those of controls.

Thirty years of the ileal-anal pouch and beyond

Still referred to as a new surgical procedure, the ileal-anal pouch or restorative proctocolectomy is now in its 30th year. Over this time the procedure has become the standard of care for patients with ulcerative colitis and familial adenomatous polyposis who require surgery. For many patients it not only eradicates disease, but also preserves the anal sphincter, therefore enabling the patient to defecate in the normal way. Much research over the years has explored optimum surgical techniques, pouch function/capacity, pouch failure and pouch satisfaction and its long-term follow-up. This article reviews literature relating to the ileal-anal pouch and traces its journey through the past three decades, providing an overview of how the pouch has evolved and considers its future development.

Ileal pouch-anal anastomosis

BACKGROUND

Since 1977, restorative proctocolectomy with ileoanal anastomosis (IAA) has evolved into the surgical treatment of choice for most patients with intractable ulcerative colitis. Construction of an ileal pouch reservoir is now standard, usually in the form of J pouch (IPAA). The aim of this report is to review selection criteria for, and functional outcomes, follow-up and management of complications of IPAA after 30 years of widespread clinical application.

METHODS AND RESULTS

Literature published in English on the clinical indications, surgical technique, morbidity, complications and outcome following IAA and IPAA was sourced by electronic search, performed independently by two reviewers who selected potentially relevant papers based on title and abstract. Additional articles were identified by cross-referencing from papers retrieved in the initial search.

CONCLUSION

The functional results of IPAA are good. Pouchitis, irritable pouch syndrome and cuffitis are specific long-term complications but rarely result in failure. Pouch salvage is possible in selected patients with poor functional outcomes. One-stage operations are increasingly performed.

The impact of preoperative immunomodulation on pouch-related septic complications after ileal pouch-anal anastomosis

PURPOSE

We studied preoperative and perioperative factors with particular attention to the role of immunomodulatory medication, which may impact the incidence of pouch-related septic complications.

METHODS

A retrospective review of data from patients who underwent ileal pouch surgery during a 20-year period from 1985 to 2005 was performed. Preoperative use of immunomodulatory medication along with perioperative clinical, surgical, and disease variables were recorded. Patients were monitored for pouch-related sepsis in the early (within 30 days of surgery) and late (after 30 days of surgery) postoperative periods. Univariate and multivariate logistic regression analysis was performed.

RESULTS

There were 445 patients (206 females; 46.4 percent). Median age was 36 (interquartile range, 27-46) years. Median follow-up period was 52 (interquartile range, 26-86) months. Complete data were available for 335 patients. Early sepsis was seen in 58 patients (17.3 percent). Another 22 patients (6.5 percent) developed late sepsis. On multivariate analysis, only steroid use remained predictive of higher rates of early sepsis (odds ratio, 1.81; 95 percent confidence interval, 1.02-3.45; P=0.002). Likewise on multivariate analysis, both male gender (odds ratio, 0.24; 95 percent confidence interval, 0.09-0.71; P=0.007) and 5-aminosalicylic-acid use (odds ratio, 0.22; 95 percent confidence interval, 0.08-0.76; P=0.023) remained predictive of lower rates of sepsis.

CONCLUSIONS

Preoperative steroid use is associated with higher rates of early but not late pouch-related septic complications. We recommend that patients be weaned of steroids before ileal pouch surgery or be warned of the higher risk of postoperative sepsis.

Ileal pouch surgery for ulcerative colitis

Ulcerative colitis (UC) is a relapsing and remitting disease characterised by chronic mucosal and submucosal inflammation of the colon and rectum. Treatment may vary depending upon the extent and severity of inflammation. Broadly speaking medical treatments aim to induce and then maintain remission. Surgery is indicated for inflammatory disease that is refractory to medical treatment or in cases of neoplastic transformation. Approximately 25% of patients with UC ultimately require colectomy. Ileal pouch-anal anastomosis (IPAA) has become the standard of care for patients with ulcerative colitis who ultimately require colectomy. This review will examine indications for IPAA, patient selection, technical aspects of surgery, management of complications and long term outcome following this procedure.

Surgical approaches to cancer in patients who have inflammatory bowel disease

IBD clearly increases the risk for GI malignancies, especially CRC. The absolute number of patients that develops such malignancies is low compared with the overall cancer rate; however, younger age of onset, higher relative risk, unique clinical presentations, and problems with early diagnosis make this a serious complication of IBD. With the exception of patients with comorbid complications, such as primary sclerosing cholangitis, the prognosis is no worse for CRCs that arise as the result of IBD compared with those that arise sporadically. The prognosis remains poor for small bowel adenocarcinomas in patients who have CD, primarily because of their advanced stage at detection. Diligent surveillance is essential for early detection and treatment of IBD-related CRCs in patients with unresected colons, long-standing or extensive disease, and in those who have early-onset CD, although pundits still question whether it significantly affects prognosis and survival. Better surveillance techniques for small bowel dysplasia or malignancy in patients who have CD is needed, especially given the poor prognosis of these patients when advanced cancers are detected. Depending on the presentation and disease diagnosis, patients have several surgical treatment options and can expect good outcomes for all. When the appropriate surgical technique is used in patients who have colon or rectal cancer, along with adjuvant chemotherapy when appropriate, prognosis and function is good; however, the experience of the surgeon can affect the prognosis for IBD-related GI cancers. Surgical therapy is based not only on general oncologic principles, but also on the surgery that is appropriate for the IBD diagnosis. Resection of the mesentery and lymphadenectomy should be performed according to oncologic principles. Postoperative survival for IBD-related CRC is good, and diligent surveillance and follow-up are critical to the patient's overall prognosis.

Revolution and evolution: 30 years of ileoanal pouch surgery

Ileal pouch-anal anastomosis (IPAA) has become the standard of care for the 25% of patients with ulcerative colitis who ultimately require colectomy. IPAA is favored by patients because it avoids the necessity for a long-term stoma. This review examines how 3 decades of experience with IPAA has molded current practice, highlighting 5- and 10-year follow-up of large series to determine durability and functional performance, in addition to causes of failure and the management of complications.

Practice parameters for the surgical treatment of ulcerative colitis

The American Society of Colon and Rectal Surgeons is dedicated to assuring high-quality patient care by advancing the science, prevention, and management of disorders and diseases of the colon, rectum, and anus. The Standards Committee is composed of Society members who are chosen because they have demonstrated expertise in the specialty of colon and rectal surgery. This committee was created to lead international efforts in defining quality care for conditions related to the colon, rectum, and anus. This is accompanied by developing Clinical Practice Guidelines based on the best available evidence. These guidelines are inclusive, and not prescriptive. Their purpose is to provide information on which decisions can be made, rather than dictate a specific form of treatment. These guidelines are intended for the use of all practitioners, health care workers, and patients who desire information about the management of the conditions addressed by the topics covered in these guidelines. It should be recognized that these guidelines should not be deemed inclusive of all proper methods of care or exclusive of methods of care reasonably directed to obtaining the same results. The ultimate judgment regarding the propriety of any specific procedure must be made by the physician in light of all of the circumstances presented by the individual patient.

The effect of ageing on function and quality of life in ileal pouch patients: a single cohort experience of 409 patients with chronic ulcerative colitis

OBJECTIVE

To evaluate in what manner ageing affects functional outcome and quality of life (QoL) in patients with chronic ulcerative colitis (CUC) after ileal pouch-anal anastomosis (IPAA).

SUMMARY BACKGROUND DATA

Short-term function and QoL after IPAA is good. However, patients are usually young, and little is known about the influence of time and ageing on long-term outcomes after IPAA.

METHODS

Using a standardized questionnaire, functional outcome, QoL, and complications were assessed prospectively in a cohort of 409 patients followed annually for 15 years after IPAA.

RESULTS

Follow-up was complete in the single cohort of 409 patients and functional and QoL outcomes summarized at 5, 10, and 15 years. Daytime stool frequency changed little (mean 6), while nighttime frequency increased from 1 stool to 2 stools. Incontinence for gas and stool increased from 1% to 10% during the day and from 2% to 24% at night over 15 years. The cumulative probability of pouchitis increased from 28% at 5 years to 38% at 10 years and to 47% at 15 years. Bowel obstruction and stricture were other principal long-term complications. At 15 years, 91% of patients had kept the same job. Work was not affected by the surgery in 83%, while social activities, sports, traveling, and sexual life all improved after surgery and did not deteriorate over time.

CONCLUSIONS

These long-term results in a single cohort of 409 IPAA patients are unique and are likely a more accurate reflection of long-term outcome than has been previously reported. These data support the conclusion that IPAA is a durable operation for patients requiring proctocolectomy for CUC; functional and QoL outcomes are good, predictable, and stable for 15 years after operation.

Surgical indications and procedures in ulcerative colitis

Chronic ulcerative colitis (CUC) is an inflammatory bowel disease limited to the mucosa of the rectum and colon. The inflammation begins in the rectum and progresses uninterrupted for variable distances. To date, no etiologic factor has been identified. However, population studies suggest there is both a genetic and environmental component contributing to the development of CUC. The natural history is one of a chronic inflammatory state, characterized by intermittent flares of disease activity. In a small number of patients, the initial presentation of CUC is of a fulminant nature. Medical therapy for the intestinal manifestations of CUC is directed at controlling symptoms through treatment of the underlying inflammatory process. Medical therapy is not curative for either the intestinal or extraintestinal manifestation of CUC. However, surgical removal of the colon and rectum cures the intestinal manifestations of the disease and eliminates or markedly reduces the associated risk of malignancy in longstanding CUC. The indications for surgical intervention are divided into two broad categories that influence the type of surgery performed: emergent and elective surgery. Emergency operations are directed at life-threatening complications of CUC and are not intended as definitive surgical treatment for CUC. Alternatively, elective surgery is intended as definitive treatment for the intestinal component of the disease. In appropriately selected patients, the best surgical treatment option is the total proctocolectomy with an ileal pouch-anal anastomosis (IPAA). The IPAA avoids the need for a permanent stoma and maintains the normal route of defecation. This is a technically demanding operation and should be performed by surgeons comfortable with the procedure. The severity and frequency of complications related to IPAA have decreased significantly since the introduction of the operations in the early 1980s. More importantly, long-term follow-up of IPAA patients has demonstrated that the functional results are durable and patient satisfaction remains high.

Patterns of disease and surgical treatment among United States veterans more than 50 years of age with ulcerative colitis

BACKGROUND

Ulcerative colitis (UC) is a clinical entity that predominantly affects young adults yet large series of middle age or elderly patients with UC are infrequently reported. The aim of this study is to identify patterns of disease, indications for operation, surgical treatment, and outcome of patients more than 50 years of age who required surgery for UC in Department of Veterans Affairs (DVA) Medical Centers.

METHODS

A population-based study on all patients in 159 hospitals of the DVA from 1997 to 2001 was carried out. Data were compiled from several national computerized VA data sets. Supplementary information including demographic information, discharge summaries, operative reports and pathology reports were obtained from local medical records. Patient variables were entered into a computerized database and analyzed using the Pearson chi-square and Fisher's exact tests. Statistical significance is designated as P < 0.05.

RESULTS

One hundred fifty-eight patients were evaluable. The mean age was 59 years (range 51-81); 99% were male. The mean duration of UC was 23 years (range 2 to 50). One hundred of the 158 patients had proctocolitis; 58 had either left-sided colitis or proctosigmoiditis. The mean dose of prednisone prior to surgery was 20 mg; the mean duration of steroid use was 8 years. The indications for elective surgery were intractability (59%), mass or stricture (27%), and dysplasia (14%). Twenty of the 158 patients (12%) were operated on emergently for either toxic colitis, perforation, or hemorrhage. One hundred three of the 158 underwent proctocolectomy and permanent ileostomy, 55 underwent a restorative proctocolectomy, and underwent a segmental colectomy. Twenty of the 158 patients were found to have dysplasia in their colectomy specimens; an additional 10 (7%) were found to have invasive cancer. Surgical morbidity was 22%. Overall mortality was 4% (7 of 158); all but 1 death occurred after emergent surgery. Mean hospitalization was 36 days (range 2 to 297).

CONCLUSIONS

Restorative proctocolectomy was performed in 36% of veterans more than 50 years of age requiring surgery for UC. The majority required surgery for intractable symptoms. Dysplasia and invasive cancer was found in 18% of patients. Mortality after surgery for acute surgical emergencies remains high.

Prospective, age-related analysis of surgical results, functional outcome, and quality of life after ileal pouch-anal anastomosis

OBJECTIVE To evaluate how age affects functional outcome and quality of life after ileal pouch anal anastomosis (IPAA). SUMMARY BACKGROUND DATA Because of the limited number of older patients undergoing IPAA, it has been difficult to assess functional outcome and quality of life stratified by age. METHODS IPAA was performed in 1895 patients. Patients were stratified by age into <45 (n = 1410), 46-55 (n = 289), 56-65 (n = 154), and more than 65 years (n = 42). Outcome was assessed prospectively. Results are presented at 1, 3, 5, and 10 years after surgery.RESULTS Patients were followed for 4.6 +/- 3.7 years (maximum, 17 years). Pouch failure occurred in 4.1% (pouch excision or permanent diversion). Incontinence and night time seepage were more common in older patients. There were minor differences in the quality of life, health, energy and happiness between age groups, with a slight benefit for those under 45 years. Fourteen percent or fewer patients experienced social, sexual or work restrictions. Overall, 96% of patients were happy to have undergone their surgery, and 98% recommended it to others. Although the respective figures were 89% and 96% in the over-65 age group, the difference was not significant. CONCLUSIONS These data provide a unique assessment of outcome after IPAA at multiple time points. Although functional outcome after IPAA is not as good in older patients, appropriate case selection confers acceptable function and quality of life to patients of all ages.

Current controversies in pouch surgery

Restorative proctocolectomy with ileal pouch anal anastomosis has become the most commonly used procedure for elective treatment of patients with mucosal ulcerative colitis and familial adenomatous polyposis. Since its original description, the procedure has been modified in an attempt to obtain optimal functional results with low morbidity and mortality, and yet provide a cure for the disease. These modifications of the technique are discussed in this review, limited to the current points of controversy. We reviewed the current literature describing restorative proctocolectomy with ileal pouch anal anastomosis. The current "hot topics" for debate are transanal mucosectomy with hand-sewn anastomosis versus the double-stapled technique, the use of diverting ileostomy, indeterminate colitis, the role of laparoscopy, and indications for pouch surgery in the elderly. Longer follow-up of patients and increased knowledge and experience with pouch surgery, coupled with active prospective evaluation of the procedure are required to settle these issues. Patients must be fully informed to understand inherent risks of each choice.

Outcome after septic complications in J pouch procedures

BACKGROUND

Despite the wide range of surgical approaches for pouch salvage, septic complications are among the main causes of pouch failure.

METHODS

This study analysed the mode and outcome of various therapeutic approaches for pouch salvage and the impact of time of diagnosis, localization and form of septic complications on the risk of pouch failure in 131 patients with septic complications of a total of 706 patients undergoing a J pouch procedure.

RESULTS

Septic complications consisted of 76.3 per cent fistulas, 15.3 per cent anastomotic breakdowns and 8.4 per cent pelvic abscesses. A total of 107 patients (81.7 per cent) with septic complications required a mean of 2.2 surgical procedures. The frequency of permanent defunctioning and excision of the pouch in the 131 patients with septic complications was 23.7 and 6.1 per cent respectively. The estimated cumulative 3-, 5- and 10-year rate of pouch failure in patients with septic complications was 19.6, 31.1 and 39.2 per cent respectively. The risk of pouch failure was significantly affected by the site of origin of septic complications (P = 0.02). The 5-year pouch failure rate increased in a subgroup of patients with septic complications at the pouch-anal anastomosis when the anal sphincter was involved (50.1 versus 29.2 per cent; P = 0.18).

CONCLUSION

Pouch failure as a result of septic complications may occur several years after ileal pouch-anal anastomosis. For prevention of pouch failure, surgery for septic complications is required in a high percentage of patients and repeated attempts are justified. Follow-up studies are required for further analysis of pouch failure.

Risk factors for ileoanal J pouch-related septic complications in ulcerative colitis and familial adenomatous polyposis

OBJECTIVE

To analyze the association between pre- and perioperative factors and pouch-related septic complications (PRSC) in ulcerative colitis (UC) and in familial adenomatous polyposis (FAP) after ileal pouch-anal anastomosis (IPAA).

SUMMARY BACKGROUND DATA

For patients with UC and FAP, IPAA is the surgical therapy of choice, but in some patients the outcome is compromised by PRSC.

METHODS

A total of 706 consecutive patients (494 UC, 212 FAP) were assessed in a study aimed at identifying subgroups of patients who were at high risk for PRSC. The rate of PRSC was analyzed as a time-dependent function (Kaplan-Meier estimation). Patients with UC and FAP were stratified separately according to associated factors (age, sex, surgeon's experience, temporary ileostomy, colectomy before IPAA, anastomotic tension, and several factors specific for UC).

RESULTS

In all, 131 (19.2%) patients had PRSC (23.4% UC, 9.4% FAP). In patients with UC, the estimated 1-year PRSC rate was 15.6% and the estimated 3-year PRSC rate was 24.2%. In patients with FAP, the estimated 1-year and 3-year PRSC rates were 9.2%. The difference between the estimated rates of PRSC was significant (P <.001). In the univariate analysis, patients with UC younger than 50 years, with severe proctitis, with preoperative hemoglobin levels less than 10 g/L, or receiving corticoid medication had a significantly higher risk for PRSC (P =.039, P =.037, P =.047, P =.003, respectively). Multivariate analysis showed that patients with UC receiving a systemic prednisolone-equivalent corticoid medication of more than 40 mg/day had a significantly greater risk of developing pouch-related complications than patients with UC receiving 1 to 40 mg/day and patients with UC who were not receiving corticoid medication (RR: 3.78, 2.25, 1, respectively, P <.001). Patients with FAP proved to have a significantly higher risk for PRSC in the univariate and multivariate analyses if anastomotic tension had occurred (RR 3.60, P =.0086).

CONCLUSIONS

Pouch-related septic complications occur as late complications and should therefore be considered in regular, specific long-term follow-up examinations. The authors identified significant risk factors for PRSC specific to patients with UC and FAP; these must be considered for each individual surgical strategy.

One- or two-stage procedure for restorative proctocolectomy: rationale for a surgical strategy in ulcerative colitis

OBJECTIVE

To analyze the results of different strategies for restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) in ulcerative colitis.

SUMMARY BACKGROUND DATA

No commonly accepted criteria exist for choosing between the one-stage or the two-stage procedure (with or without temporary diverting ileostomy) for IPAA. The authors analyzed the outcome of patients principally suitable for either of the two alternative surgical strategies.

METHODS

A matched-pair control study was performed, comparing surgical details and the early and late outcome of the one-stage (study group, n = 57) versus the two-stage procedure (control group, n = 114), for IPAA.

RESULTS

No differences were found between the study group and the control group regarding the matching criteria gender, median age at IPAA, systemic corticoid medication, or activity of colitis. Comparing the patients who underwent a one-stage procedure with those who underwent a two-stage procedure, the proportion of patients without complications was significantly higher (P =.0042) and the frequency of late complications was significantly lower (P =.0022) in patients who underwent the one-stage procedure. The percentage of patients with anastomotic strictures was significantly higher in the control group than in the study group (P =.0022). No significant difference was found between the two groups regarding early complications, pouch-related septic complications, pouchitis, median duration of surgery for IPAA, median blood loss, need for transfusion, or median hospital stay.

CONCLUSIONS

In patients with ulcerative colitis in whom there is a choice between a one-stage procedure or a two-stage procedure with a defunctioning ileostomy, the one-stage procedure is clearly superior. This finding is of great clinical relevance both for the subjective interests of the patient and from an economic point of view.

Surgical Management of Inflammatory Bowel Disease

Surgery continues to be a central component in the treatment of patients with inflammatory bowel disease (IBD). The most important aspect of caring for patients with IBD is a close and ongoing interaction between the surgeon and gastroenterologist both before and after surgery. Surgery in patients with chronic ulcerative colitis (CUC) is curative. In the appropriate patient, we recommend proctocolectomy with ileal pouch anal anastomosis (IPAA). In contrast, patients with Crohn's disease cannot be cured with surgery. Instead, surgery is used in conjunction with maximal medical therapy to treat symptoms of the disease and improve the patient's quality of life. Surgical interventions should be limited in scope. Small bowel disease should be treated with either limited resection or strictureplasty, if possible, to conserve bowel length. For limited involvement of the colon, segmental resection yields good results. Minimal surgical intervention, drainage of abscesses, placing draining setons, and aggressive medical therapy is recommended as treatment of perianal Crohn's disease.

Factors influencing the functional outcome of restorative proctocolectomy in ulcerative colitis

BACKGROUND

Restorative proctocolectomy is considered to be the procedure of choice in the operative treatment of ulcerative colitis. The aim of this study was to evaluate the functional outcome following operation and to identify possible predictive factors.

METHODS

Some 168 patients (median age 32 years, 102 men) with ulcerative colitis underwent restorative proctocolectomy. The functional outcome was evaluated by a symptom index created from a questionnaire at a median of 29 (13-123) months of follow-up. The records of these patients were reviewed, and preoperative, peroperative and postoperative variables were registered and related to outcome.

RESULTS

The response rate to the questionnaire was 155 (92 per cent) of 168. The symptom index was related to patients' overall assessment of outcome. In spite of a perceived good result many patients experienced a number of symptoms. Age over 50 years (P < 0.01), presence of extraintestinal manifestations (P < 0.05) and late complications, such as anastomotic stricture (P < 0.05), pouchitis (P < 0.01) and anal pain (P < 0.05), were related to a less favourable outcome.

CONCLUSION

While preoperative data may help in selecting patients suitable for restorative proctocolectomy, prevention of late complications seems most important in improving the functional outcome.
