Colectomy for acute colitis: is it safe to close the rectal stump?

Surgical Emergencies in Inflammatory Bowel Disease

Inflammatory bowel disease (IBD) patients are at risk for undergoing emergency surgery for fulminant disease, toxic megacolon, bowel perforation, intestinal obstruction, or uncontrolled gastrointestinal hemorrhage. Unfortunately, medical advancements have failed to significantly decrease rates of emergency surgery for IBD. It is therefore important for all acute care and colorectal surgeons to understand the unique considerations owed to this often-challenging patient population.

Management of Rectal Stump During Laparoscopic Subtotal Colectomy for Inflammatory Bowel Disease: A Comparative Cohort Study from Six Referral Centres

BACKGROUND AND AIMS

There is no consensus on the best management of the rectum after subtotal colectomy for refractory colitis complicating inflammatory bowel disease [IBD]. The objective was to evaluate the impact of rectal stump management during laparoscopic subtotal colectomy [LSTC] for IBD.

METHODS

Patients who underwent LSTC with double-end ileo-sigmoidostomy [Gr.A] or end ileostomy with closed rectal stump [Gr.B] for IBD were included from a retrospective database of six European referral centres.

RESULTS

In total, 314 patients underwent LSTC and were allocated to Gr.A [n = 102] and B [n = 212]. After LSTC, stoma-related complications occurred more frequently in Gr.A [12%] than in Gr.B [4%, p = 0.01]. Completion proctectomy with ileal pouch-anal anastomosis [IPAA] was performed as a three-stage procedure in all patients from Gr.A, and in 88 patients from Gr.B [42%; Gr.B1]. The other 124 patients from Gr.B underwent a modified two-stage procedure [58%; Gr.B2]. The second stage was performed laparoscopically in all patients from Gr.A compared with 73% of Gr.B1 [p < 0.0001] and 65% of Gr.B2 patients [p < 0.0001]. When laparoscopy was intended for 2nd stage IPAA, conversion to laparotomy occurred less frequently in Gr.A when compared with B1 [0 vs 5%, p = 0.06] or B2 [10%, p = 0.001]. When all surgical stages were included [LSCT and IPAA], cumulative stoma-related complications occurred more frequently in Gr.A [n = 19] than in Gr.B1 [n = 6, p = 0.02] and Gr.B2 [n = 6, p = 0.001].

CONCLUSION

This study suggests that both techniques of double-end ileosigmoidostomy and end ileostomy with closed rectal stump are safe and effective for rectal stump management after laparoscopic subtotal colectomy.

Colectomy with ileostomy for severe ulcerative colitis-postoperative complications and risk factors

PURPOSE

In the era of biological therapy of ulcerative colitis (UC), surgical treatment frequently consists of colectomy, end ileostomy, and rectal stump closure before patients go on towards restorative proctocolectomy. We aimed to evaluate possible risk factors for the occurrence of postoperative complications and investigate those after initial colectomy in these patients.

METHODS

Retrospective analysis of 180 patients (76 female, 104 male) undergoing colectomy for UC with formation of a rectal stump and terminal ileostomy between March 2008 and March 2018 at Charité University Hospital Berlin, Campus Benjamin Franklin. A panel of possible postoperative complications was established, patient history was screened, and postoperative complications were analyzed using the Clavien Dindo Classification.

RESULTS

Postoperative complication rate was 27.7%. Mortality was 0.5%. Postoperative ileus occurred in 15.3% and rectal stump leakage in 14.8%. Complications were categorized as Clavien Dindo 3 in 80%. Risk factors for surgical complications after multivariate analysis were ASA classification (p = 0.004), preoperative anemia (Hemoglobin < 8 mg/dl) (p = 0.025), use of immunosuppressants (p = 0.003), more than two cardiovascular diseases (p = 0.016), and peritonitis (p = 0.000). Reoperation rate of patients with surgical complications was 27.7%.

CONCLUSION

Colectomy in high-risk UC patients is associated with significant morbidity. However, most of the surgical complications can be treated conservatively. Overall mortality is low. Patient-related risk factors are associated with postoperative complications. Optimizing these risk factors or earlier indication for surgery in the course of UC may help to reduce morbidity of this procedure.

Systematic review of rectal stump management during and after emergency total colectomy for acute severe ulcerative colitis

BACKGROUND

There is no consensus about the optimal management of the rectal stump after an emergency subtotal colectomy in patients with acute severe ulcerative colitis (ASUC). The aim was to perform a systematic review of the published literature on the surgical and medical management of the rectal stump after an emergency (sub) total colectomy in patients with ASUC.

METHODS

The following databases were searched, MEDLINE (PubMed), EMBASE and OVID SP, from January 1993 to March 2018. Studies that reported post-operative outcomes after surgical and/or medical management of the rectal stump after emergency (sub) total colectomy in adults with ASUC were included. Two independent assessors reviewed eligible articles.

RESULTS

A total of 11 studies met the inclusion criteria. All were case series and included 476 patients. Regarding surgical management, five studies reported on closed subcutaneous placement of the rectal stump, seven on intraperitoneal placement and two on the formation of a formal mucous fistula. The lowest reported pelvic sepsis rate was in patients with subcutaneous closure of the rectal stump (n = 144, 2%) and lowest wound infection rate was reported after intraperitoneal closure (n = 268, 7.8%). The highest rate of mortality was reported after intraperitoneal placement of the rectal stump (n = 268, 1.5%). There were insufficient data reported on medical management for any comparison.

CONCLUSION

Subcutaneous placement of the rectal stump was associated with the lowest morbidity and mortality rate, although data are of limited quality and insufficient to guide practice recommendations.

The rectal remnant after total colectomy for colitis - intra-operative,post-operative and longer-term considerations

OBJECTIVES

Acute severe colitis requires surgery in around 30% of the cases. Total colectomy with ileostomy is the standard procedure with distinct advantages to a laparoscopic approach. Less agreement exists regarding the formation or configuration of the retained rectal stump and its short-term and long-term management. In this review, aspects of management of the rectal remnant, including perioperative considerations, potential complications, medical treatment, surveillance and implications for proctectomy and reconstructive surgery are explored.

METHODS

A thorough literature review exploring the PubMed and EMBASE databases was undertaken to clarify the evidence base surrounding areas of controversy in the surgical approach to acute severe colitis. In particular, focus was given to evidence surrounding management of the rectal remnant.

RESULTS

There is a paucity of high quality evidence for optimal management of the rectal stump following colectomy, and randomised trials are lacking. Establishment of laparoscopic colectomy has been associated with distinct advantages as well as the emergence of unique considerations, including those specific to rectal remnant management.

CONCLUSIONS

Early surgical involvement and a multidisciplinary approach to the management of acute severe colitis are advocated. Laparoscopic subtotal colectomy and ileostomy should be the operation of choice, with division of the rectum at the pelvic brim leaving a closed intraperitoneal remnant. If the rectum is severely inflamed, a mucus fistula may be useful, and an indwelling rectal catheter is probably advantageous to reduce the complications associated with stump dehiscence. Patients electing not to proceed to proctectomy should undergo surveillance for dysplasia of the rectum.

The Association of Coloproctology of Great Britain and Ireland consensus guidelines in surgery for inflammatory bowel disease

AIM

There is a requirement of an expansive and up to date review of surgical management of inflammatory bowel disease (IBD) that can dovetail with the medical guidelines produced by the British Society of Gastroenterology.

METHODS

Surgeons who are members of the ACPGBI with a recognised interest in IBD were invited to contribute various sections of the guidelines. They were directed to produce a procedure based document using literature searches that were systematic, comprehensible, transparent and reproducible. Levels of evidence were graded. An editorial board was convened to ensure consistency of style, presentation and quality. Each author was asked to provide a set of recommendations which were evidence based and unambiguous. These recommendations were submitted to the whole guideline group and scored. They were then refined and submitted to a second vote. Only those that achieved >80% consensus at level 5 (strongly agree) or level 4 (agree) after 2 votes were included in the guidelines.

RESULTS

All aspects of surgical care for IBD have been included along with 157 recommendations for management.

CONCLUSION

These guidelines provide an up to date and evidence based summary of the current surgical knowledge in the management of IBD and will serve as a useful practical text for clinicians performing this type of surgery.

The type of stoma matters-morbidity in patients with obstructing colorectal cancer

PURPOSE

A loop colostomy may reduce the risk of severe intraabdominal complications in patients with obstructing colorectal cancer compared to an end colostomy. The aim of this study was to relate complications to the type of stoma, and a secondary aim was to evaluate whether the type of colostomy had an impact on time until oncological/surgical treatment.

METHODS

All patients who underwent surgery and received a deviating colostomy due to obstructing colorectal cancer between January 2011 and December 2015 in five Swedish hospitals in Region Västra Götaland were included (n = 289). Patient charts were reviewed retrospectively. Patients alive in the end of 2016 were contacted and were sent a questionnaire including questions about stoma function and health-related quality of life.

RESULTS

Some 289 patients were included; 147 received an end colostomy and 140 a loop colostomy. Two patients were excluded from the analysis due to missing data. There was no difference in complications at 90 days between the two groups, 44% (end colostomy) and 54% (loop colostomy) (odds ratio: 0.83 (95% CI: 0.49; 1.41). Time to start of treatment was similar in both groups. Patients with a loop colostomy had significantly higher stoma-related morbidity with retraction, prolapse, leakage and bandaging problems. No differences in quality of life were found.

CONCLUSION

The hypothesis that a loop colostomy reduced complications could not be confirmed. An end colostomy should be the first choice in these patients particularly in patients who will have their colostomy for the remainder of their life to reduce stoma-related symptoms.

Surgery in ulcerative colitis: When? How?

Ulcerative Colitis (UC) is an idiopathic chronically-remitting inflammatory bowel disorder characterized by a contiguous inflammation of the colonic mucosa affecting the rectum that generally extends proximally in a continuous manner through the entire colon. Patients typically experience intermittent exacerbations, with symptoms characterized by bloody diarrhea associated with urgency and tenesmus. The anatomical extent of mucosal involvement is the most important factor determining disease course and is an important predictor of colectomy. The precise etiology of UC is unknown. However, a combination of genetic predisposition and environmental factors seems to have a key role in the development of the disease. UC usually is mildly active but it can be a life-threatening condition because of colonic and systemic complications, and later in the disease course due to the development of colorectal cancer. Interestingly, even if pathogenetic features detected in patients with sporadic CRC can be also found in UC-related colorectal cancer (UC-CRC), this latter is, usually, driven by an inflammation-driven pathway rising from a non-neoplastic inflammatory epithelium to dysplasia to cancer. Thus, a long-term follow-up with colonoscopy surveillance has been recommended. Approximately 15% of UC patients develop an acute attack of severe colitis, and 30% of these patients require colectomy. The initial treatment strategy in UC typically follows the traditional step-up approach. One third of the patients will not respond to steroid therapy and cyclosporine and infliximab are the most common salvage agents employed in these cases in order to avoid emergent surgery. Unfortunately, although a significant short-term benefit have been observed after infliximab treatment, the colectomy rate have remained stable. Surgery in UC depends on the stage of the disease as well as patient's status and is divided into the following settings: urgent, emergent and elective. Despite many efforts the surgical management of UC remains a significant challenge. A multidisciplinary management of UC is key in order to define the best timing and the best procedure for each patient in an individualized basis.

Probability, rate and timing of reconstructive surgery following colectomy for inflammatory bowel disease in Sweden: a population-based cohort study

AIM

Many patients with inflammatory bowel disease (IBD) need colectomy, but the rate of reconstructive surgery with restoration of intestinal continuity is unknown. The aim of this study was to investigate the probability, rate and timing of reconstructive surgery after colectomy in patients with IBD in a population-based setting.

METHOD

The study cohort included all patients with IBD in Sweden who underwent colectomy from 2000 to 2009. Each patient was followed from admission for colectomy to admission for reconstructive surgery, date of death, migration or 31 December 2010. Kaplan-Meier survival curves and multivariable Poisson regression models were used to describe the probability, rate and timing of reconstructive surgery.

RESULTS

Out of 2818 IBD patients treated with colectomy, 61.0% were male and 78.9% had ulcerative colitis. No reconstructive surgery had been performed in 1595 (56.6%) patients by the end of follow-up. Of the remaining 1223 patients, 526 underwent primary reconstructive surgery and 697 had a secondary reconstruction following a median interval of 357 days from primary surgery in the form of colectomy. The probability of reconstructive surgery was dependent on age (55.6% and 18.1% at ages 15-29 and ≥ 59 years, respectively), and the chance of reconstructive surgery was higher in hospitals that performed more than 13 colectomies for IBD per year [incidence rate ratio and 95% confidence interval 1.27 (1.09-1.49)].

CONCLUSION

Fewer than half of the patients having a colectomy for IBD underwent subsequent reconstructive surgery. Older age and low hospital volume were risk factors for no reconstructive surgery.

Surgical and medical treatment in patients with acute severe ulcerative colitis

Ulcerative colitis (UC) is a chronic inflammatory disease of the mucosa of the colorectum. The treatment of UC depends on the severity of symptoms and the extent of the disease. Acute severe colitis (ASC) occurs in 12-25% of patients with UC. Patients with ASC must be managed by a multidisciplinary team. Medically or surgically aggressive treatment is carried out with the final aim of reducing mortality. Intravenous administration of corticosteroids is the mainstay of the therapy. Medical rescue therapy based on cyclosporine or infliximab should be considered if there is no response to corticosteroids for 3 days. If there has been no response to medical rescue therapy after 4-7 days, the patient must undergo colectomy in emergency surgery. Prolonged observation is counterproductive, as over time it increases the risk of toxic megacolon and perforation, with a very high mortality rate. The best potential treatment is subtotal colectomy with ileostomy and preservation of the rectum. Emergency surgery in UC should not be seen as a last chance, but can be considered as a life-saving procedure. Colectomies in emergency setting are characterized by high morbidity rates but the mortality is low.

Management of acute colitis and toxic megacolon

Severe colitis is a well-defined condition that can develop in patients afflicted with ulcerative colitis, but typically responds to a variety of medical therapies. Operative intervention is warranted when massive hemorrhage, perforation, or peritonitis complicates the clinical scenario or medical therapy fails to control the disease. Of the operative options, total/subtotal colectomy and end ileostomy is the usual procedure of choice especially if the operation can be performed through a laparoscopic approach.

The surgical options and management of intestinal Crohn's disease

Crohn's disease (CD) is a pan-gastrointestinal illness. It is notorious for recurrences which can develop in any segment of the gastrointestinal tract. There are many indications and surgical options for intestinal Crohn's disease . We discuss these options based on the current literature. It is important to note however, that operative treatment is based on the correct diagnosis, clinical presentation, sphincter function and patient motivation. Early and timely referral to a surgeon is paramount. The goals of continued medical therapy need to be clearly defined as do the criteria for referral to surgery.

Perioperative complications in inflammatory bowel disease

Almost 50% of patients with inflammatory bowel disease (IBD) will undergo surgery for their disease at some stage of its clinical course. Complications seen following surgery may occur early or late in the postoperative period. Patient factors, including active inflammatory disease, malnutrition, and use of immunosuppressant medications, make these patients a challenging surgical group and at increased risk for surgical complications. The purpose of this review is to characterize the complications that are commonly seen following surgery in patients with IBD and to discuss the surgical and patient factors that may influence their development.

Surgical management of acute colitis and toxic megacolon

Toxic colitis, also known as fulminant colitis, or toxic megacolon when associated with bowel dilation, remains a significant emergent problem in patients with ulcerative colitis. The surgical options differ when compared with the patient undergoing elective resection for this disease and are influenced by the patients' overall medical status. Generally the options are total abdominal colectomy with ileostomy, and proctocolectomy with ileostomy or pouch reconstruction. In few circumstances, a decompressing colostomy and loop ileostomy may be performed. More recently, laparoscopy has been employed. The general surgical recommendations, indications, and techniques will be discussed.

Colectomy in patients with acute colitis: a systematic review

BACKGROUND

For patients with acute colitis, the decision when and how to operate is difficult in most cases. It was the aim of this systematic review to analyze early mortality and morbidity of colectomy for severe acute colitis in order to identify opportunities to improve perioperative treatment and outcome.

METHODS

A systematic review of the available literature in the Medline and PubMed databases from 1975 to 2007 was performed. All articles were assessed methodologically; the articles of poor methodological quality were excluded. Articles on laparoscopic colectomy for acute colitis were analyzed separately.

RESULTS

In total, 29 studies met the criteria for the systematic review, describing a total of 2,714 patients, 1,257 of whom were operated on in an acute setting, i.e., urgent or emergency colectomy. Reported in-hospital mortality was 8.0%; the 30-day mortality was 5.2%. Morbidity was 50.8%. The majority of complications were of infectious and thromboembolic nature. Over the last three decades, there was a shift in indications from toxic megacolon, from 71.1% in 1975-1984 to 21.6% in 1995-2005, to severe acute colitis not responding to conservative treatment, from 16.5% in 1975-1984 to 58.1% in 1995-2007. Mortality decreased from 10.0% to 1.8%. Morbidity remained high, exceeding 40% in the last decade. Mortality after laparoscopic surgery was 0.6%. Complication rate varies from 16-37%.

CONCLUSION

Colectomy for acute colitis is complicated by considerable morbidity. The incidence of adverse outcome has substantially decreased over the last three decades, but further improvements are still required. The retrospective nature of the included studies allows for a considerable degree of selection bias that limits robust and clinically sound conclusions about both conventional and laparoscopic surgery.

Outcomes of the rectal remnant following colectomy for ulcerative colitis

OBJECTIVE

Controversy surrounds the optimal surgical management of the distal rectal remnant during colectomy for ulcerative colitis (UC) and the potential benefit from the placement of a rectal catheter for remnant drainage. This study reviews the clinical outcomes of patients who have undergone colectomy for UC with intra-peritoneal closure of the rectal remnant.

METHOD

Analysis of prospective data lodged on Lothian Surgical Audit databases from patients treated in a tertiary coloproctology unit over 11 years.

RESULTS

One hundred and fifty-nine patients were identified, the mean age was 41.9 years, 63% were men. Failure of maximal medical therapy necessitated surgery for 78.1% patients, while 12.6% had acute perforation and 11.9% had toxic megacolon. Complications included five (3.1%) stump dehiscences, eight (5.0%) intra-abdominal/pelvic collections, four (2.5%) significant wound infections, three (1.9%) small bowel obstructions and three (1.9%) deaths. Within the follow-up period, 62.3% patients had an ileo-pouch anal anastomosis (IPAA), 7.5% patients had a completion proctectomy, 10.1% patients within the series had a retained rectal remnant after 1 year follow up, the remaining patients had less than 1 year follow up.

CONCLUSION

The intra-peritoneal rectal stump following colectomy for UC is associated with low rates of pelvic sepsis and a high proportion of patients successfully proceeding to IPAA.

Surgery for ulcerative colitis

Ulcerative colitis is an inflammatory condition of unknown aetiology affecting all or part of the rectum and colon. The mainstay of treatment is medical but there are specific indications for surgical intervention. This article reviews the evolution of surgical management and in particular compares outcome from proctocolectomy and pouch surgery. A number of factors determining choice of procedure are examined, including elective or emergency presentation, patient selection, technical issues, morbidity and quality of life. Emphasis is made regarding a full explanation of these factors so that the patient is fully involved in the final decision regarding choice of procedure.

Operative management of Crohn's disease of the colon including anorectal disease

Evaluation and management of the patient who has Crohn's disease of the colon, rectum, and anus is challenging for even the most experienced provider. Because of its broad spectrum of presentation, recurrent nature, and potential for high morbidity, the surgeon needs to not only treat the acute situation but also keep in mind the potential long-term ramifications. Although there are exciting new medications and treatment modalities yielding promising results, surgery continues to remain at the forefront for the care of these patients. This article reviews various surgical options for the patient who has Crohn's disease of the colon, rectum, and perianal region with emphasis on symptomatic resolution and optimization of function.

Management of the rectal stump after emergency sub-total colectomy: which surgical option is associated with the lowest morbidity?

OBJECTIVE

To identify the preferred surgical management of the rectal stump after emergency subtotal colectomy (ESC) for acute severe colitis by assessing the morbidity associated with each option.

PATIENTS AND METHODS

Consecutive patients undergoing ESC at a district general hospital between 1999 and 2004 were retrospectively audited for pathology, rectal stump complications and length of postoperative hospital stay (POS).

RESULTS

Thirty-seven ESCs were performed, 34 were undertaken for disease refractory to medical treatment, 2 for toxic mega colon and 1 for perforation. Thirty-four cases were for ulcerative colitis, 2 Crohn's colitis and 1 infective colitis. Twenty-seven had an intraperitoneal and 10 a subcutaneously placed closed rectal stump. The median POS for patients with a subcutaneously placed stump was shorter than for those with an intraperitoneal stump, 8 and 15 days, respectively (P = 0.04). Two patients had leakage from an intraperitoneal stump, prolonging POS (33 and 193 days). Three of the subcutaneous stumps leaked causing wound infection but not prolonging the POS (6, 7 and 16 days).

CONCLUSION

Avoiding a second stoma by closing the rectal stump after ESC has been confirmed as acceptable practice by studies over the last 15 years, reporting no overall increase in complications. The location of a closed rectal stump appears to influence the incidence of pelvic sepsis. The lowest pelvic sepsis rate is associated with subcutaneous placement; despite a higher wound infection rate this option appears to be associated with a lower total morbidity reflected in a shorter POS.
