Intersphincteric proctectomy with end-colostomy for anorectal Crohn's disease results in early and severe proximal colonic recurrence

Long-term outcomes of 'temporary' defunctioning in patients with severe perianal Crohn's disease

AIM

This study aimed to analyse long-term outcomes in patients undergoing temporary faecal diversion for therapy-refractory Crohn's perianal fistulas.

METHODS

In this retrospective study, Crohn's patients who underwent defunctioning for perianal disease between 2012 and 2022 were included. The primary endpoints were successful ostomy reversal and proctectomy/proctocolectomy rates. Secondary endpoints were clinical fistula closure, development of proximal colonic disease recurrence, and the influence of medication, patient and disease characteristics on ostomy reversal.

RESULTS

In total, 53 patients were included, 35 colostomies and 18 ileostomies. Previous L2 disease was more frequently seen in the ileostomy group (colostomy 29%, ileostomy 83%; P = 0.004). Clinical closure of the fistula was seen in 26%. 21% (11/53 patients) underwent an attempt at ostomy reversal during a median overall follow-up of 90.1 months (interquartile range 17.5-82.5) of which nine ostomies (colostomy 23%, ileostomy 6%; P = 0.244) were closed successfully. In 35%, a proctectomy/proctocolectomy was required to control ongoing perianal sepsis. Factors associated with ostomy reversal were fistula closure (P < 0.001) and L1/L3 disease (P = 0.043). In patients with ostomy reversal attempt (n = 11), successful reversal was associated with colostomy (P = 0.055) and use of anti-tumour necrosis factor (anti-TNF) (P = 0.055) despite being previously classified as anti-TNF refractory.

CONCLUSION

Ostomy reversal rates are low, so defunctioning ostomies should be carefully considered because in most patients the ostomy will be permanent. In one-third of the patients, a proctectomy/proctocolectomy is required to treat ongoing perianal sepsis. If a patient is eligible for ostomy reversal, reversal should preferably be done under anti-TNF to optimize chances of success.

Turnbull-Cutait abdominoperineal pull-through operation: The Cleveland Clinic experience in the 21st century

AIM

The Turnbull-Cutait pull-through procedure (TCO) restores intestinal continuity in the setting of chronic pelvic sepsis, colorectal anastomotic leak, complex pelvic fistulas and technical challenges related to complicated rectal cancer. The aim of this study was to evaluate the outcomes of the TCO for salvaging complex pelvic conditions and to compare it to hand-sewn immediate coloanal anastomosis (CAA).

METHODS

This is a retrospective single-institution study where we searched a prospectively maintained database to identify patients who underwent the TCO. Patient demographics, operative indications and outcomes were analysed. TCO success was defined as maintenance of intestinal continuity and being stoma-free. Kaplan-Meier analysis was employed for stoma-free survival analysis.

RESULTS

A total of 81 patients with TCO and 129 patients with CAA were included. The TCO success rate was 69% at a median of 1.4 years' follow-up with 25 (31%) patients ending up with a permanent stoma compared to 22 (17%) in the CAA group with a median follow-up of 4 years (P = 0.03). The Kaplan-Meier cumulative incidence of TCO success at 1, 3 and 5 years was 79%, 60% and 51%, respectively, compared to 91%, 81% and 73% after CAA.

CONCLUSION

The TCO has a high success rate for patients with complex pelvic conditions who may be facing a permanent stoma as their only option.

Surgical Management of Crohn's Disease

Treatment of Crohn's disease (CD) focuses on providing acceptable quality of life for the affected individual by optimizing medical therapy, endoscopic procedures, and surgical intervention. Biologics have changed the medical management of moderate to severe CD. However, despite their introduction, the need for surgical resection in CD has not drastically changed, with two-thirds of the patients still requiring an intestinal resection. Patient outcomes are optimized by focusing on preoperative management and intraoperative technical aspects to maximize bowel preservation. This article reviews some of the important principles of Crohn's surgery to help guide surgeons when approaching this challenging patient population.

Anorectal Strictures in Complex Perianal CD: How to Approach?

Anorectal strictures are a notoriously difficult to treat phenotype of perianal Crohn's disease. Quality of life is diminished due to ongoing pain, incontinence, difficulty with stool evacuation, and recurrent medical and surgical treatments. Medical therapy is aimed at treating luminal disease and mucosal ulceration to prevent worsening of fibrosis. Clinical examination and endoscopic intervention can be used for serial dilations of strictures. Unfortunately, despite optimal medical therapy and endoscopic intervention with serial anal dilations, surgery with intestinal diversion or proctocolectomy may be required as part of the treatment algorithm in a significant proportion of patients.

Colonic disease recurrence following proctectomy with end colostomy for anorectal Crohn's disease

AIM

In patients with anorectal Crohn's disease, it remains uncertain whether a total proctocolectomy with end ileostomy or proctectomy with end colostomy should be recommended due to the unknown rate of disease recurrence in the remaining colon.

METHODS

A retrospective review of all patients with a known diagnosis of Crohn's disease who underwent a proctectomy with end colostomy for distal Crohn's disease between January 1, 2010 and January 1, 2019 at two IBD referral centres was conducted. Data collected included patient demographics, surgical variables at the time of proctectomy, and postoperative clinical, endoscopic and surgical recurrence rates.

RESULTS

A total of 63 patients were included; mean age was 47 years (SD 15 years) and 32 (50.8%) were female. The majority of patients underwent a proctectomy with end colostomy (n = 56; 88.9%) while the remaining seven patients (11.1%) underwent a proctectomy with end colostomy and concurrent ileocectomy. A total of 55 patients (87.3%) had proctitis, 51 (81%) had perianal fistulating disease, and 34 (54%) had anal canal stenosis or ulceration. Most patients had medically refractory disease (n = 54; 85.7%) versus neoplasia (n = 9; 14.3%). The median length of long-term follow-up was 17.7 months (IQR: 4.72, 38.7 months). During that time, 14 (22.2%) experienced clinical recurrence, 10 of 34 evaluated (29.4%) had endoscopic recurrence, and 3 (4.76%) required a completion total abdominal colectomy for recurrent medically refractory disease in the colon.

CONCLUSION

Colonic recurrence remains low following proctectomy and descending colostomy suggesting this operative management strategy is reasonable in Crohn's patients with distal disease.

Practical insights into stomas in inflammatory bowel disease: what every healthcare provider needs to know

PURPOSE OF REVIEW

Despite advances in medical and surgical therapy in inflammatory bowel disease (IBD) management, intestinal stomas can be needed in a significant proportion of patients. The impact of stomas in patients' lives is significant, and the topic is still challenging for different specialties involved in IBD care.

RECENT FINDINGS

Indications for intestinal ostomies in IBD can occur in elective (malnutrition, anemia, or previous steroids) or emergency (perforation, abdominal abscess, obstruction) settings. Different types of stomas can be used (loop, end, or double loop ostomies) depending on different clinical scenarios. Ileostomies are more frequently needed in IBD patients than colostomies, which may be associated with higher rates of recurrence in Crohn's disease. Only 16.6% of patients with diverting stomas for perianal Crohn's disease have successful transit restoration, and stomas become permanent. Prevention of complications is based on adequate preoperative demarcation and meticulous surgical technique. IBD stoma-related morbidity can occur in up to 70% of patients, are more common in Crohn's disease, and can be classified into early or late complications.

SUMMARY

A multidisciplinary approach including gastroenterologists, surgeons, and stoma nurses is essential for IBD patients who will face the challenge of having a stoma during their disease course.

Clinicopathological and prognostic evaluations of anorectal cancer after fecal diversion for patients with Crohn's disease

PURPOSE

Colorectum diversion with a proximal stoma is often the preferred surgical approach in patients with Crohn's disease-related anorectal lesions or refractory colitis. To date, few studies have assessed the incidence and prognosis of cancer in the diverted anorectal segments. This study aimed to evaluate the clinical characteristics and prognosis of anorectal cancer associated with Crohn's disease following fecal diversion.

METHODS

This was a retrospective study based on medical records of patients diagnosed with Crohn's disease between 1999 and 2020. It was conducted at Yokohama Municipal Citizen's Hospital. Patients diagnosed with anorectal cancer following fecal diversion were identified, and their prognosis was the primary outcome measure.

RESULTS

Among 1615 patients, 232 patients (14%) underwent colorectum diversion. Of those 232 patients, 11 were diagnosed with anorectal cancer following fecal diversion, ten were diagnosed with advanced cancer, 10 underwent abdominoperineal resection, and eight died. 1 could not undergo resection due to multiple lung metastasis and died. The overall five-year survival rate in patients diagnosed with anorectal cancer following fecal diversion was 20%.

CONCLUSION

Crohn's disease-associated anorectal cancer following fecal diversion was challenging to diagnose early, and patients had a poor prognosis even after curative resection. Early abdominoperineal resection may be considered for patients with Crohn's disease who cannot benefit from cancer screening and surveillance due to difficulty accessing the anorectal stricture via endoscopy.

Surgical management of Crohn's disease: a state of the art review

PURPOSE

The aim of this review was to examine current surgical treatments in patients with Crohn's disease (CD) and to discuss currently popular research questions.

METHODS

A literature search of MEDLINE (PubMed) was conducted using the following search terms: 'Surgery' and 'Crohn'. Different current surgical treatment strategies are discussed based on disease location.

RESULTS

Several surgical options are possible in medically refractory or complex Crohn's disease as a last resort therapy. Recent evidence indicated that surgery could also be a good alternative in terms of effectiveness, quality of life and costs as first-line therapy if biologicals are considered, e.g. ileocolic resection for limited disease, or as part of combination therapy with biologicals, e.g. surgery aiming at closure of select perianal fistula in combination with biologicals. The role of the mesentery in ileocolic disease and Crohn's proctitis is an important surgical dilemma. In proctectomy, evidence is directing at removing the mesentery, and in ileocolic disease, it is still under investigation. Other surgical dilemmas are the role of the Kono-S anastomosis as a preventive measure for recurrent Crohn's disease and the importance of (non)conventional stricturoplasties.

CONCLUSION

Surgical management of Crohn's disease remains challenging and is dependent on disease location and severity. Indication and timing of surgery should always be discussed in a multidisciplinary team. It seems that early surgery is gradually going to play a more important role in the multidisciplinary management of Crohn's disease rather than being a last resort therapy.

Management of Isolated Anal Strictures in Crohn's Disease

BACKGROUND

Anorectal stricturing is a particularly morbid manifestation of Crohn's disease resulting in a diminished quality of life related to pain, incontinence, and recurrent operative interventions.

OBJECTIVE

To determine the role of medical therapy, endoscopic dilation, and surgical intervention for the treatment of isolated anorectal stricturing.

DATA SOURCES

An organized search of MEDLINE, PubMed, EMBASE, Scopus, and the Cochrane Database of Collected Reviews was performed from January 1, 1990 through May 1, 2020.

STUDY SELECTION

Full text papers which included management of isolated anorectal strictures in the setting of Crohn's disease.

INTERVENTION(S)

Medical and surgical management.

MAIN OUTCOME MEASURES

Symptomatic relief, need for proctocolectomy.

RESULTS

Our search identified a total of 553 papers; after exclusion based on title (n = 430) and abstract (n = 47), 76 underwent full text review with 65 relevant to the management of anorectal strictures. A summary of the retrospective reports suggests that medical therapy can help control luminal inflammation, but fibrosis may ultimately set in resulting in a need for endoscopic or surgical intervention. Surgical options are limited in the anal canal due to inflammation and ulceration and concomitant perianal fistulizing disease. While fecal diversion can provide symptomatic relief, successful restoration of intestinal continuity remains uncommon and most patients ultimately undergo a total proctocolectomy with end ileostomy.

LIMITATIONS

Limited literature published, all retrospective in nature.

CONCLUSIONS

Despite significant advances in medical and surgical therapy in Crohn's disease over the last decades, there is clearly an unmet need in the management of anorectal strictures in Crohn's disease.

Elective Abdominal Surgery for Inflammatory Bowel Disease

Elective abdominal surgery for inflammatory bowel disease is common. Surgery for Crohn's disease is not curative, and treatment must be individualized to the disease process. Surgery for ulcerative colitis generally is curative but consideration of patient-specific factors is important for staging of the procedure and determining whether ileal pouch-anal anastomosis is appropriate.

Risk factors for proctectomy in consecutive Crohn's colitis surgical patients in a reference colorectal centre

PURPOSE

Crohn's colitis carries a risk for permanent stoma with extirpation of the rectum. We aimed to estimate the proctectomy rate and identify risk factors for proctectomy in patients with Crohn's colitis.

METHODS

For this study, we retrospectively reviewed data from consecutive patients with Crohn's disease (CD) affecting the colon or anorectal region undergoing bowel resection in a reference colorectal centre between 2006 and 2016. The cumulative risk for proctectomy was calculated using the Kaplan-Meier curve. We used univariate and multivariate logistic regression analyses to determine independent risk factors for proctectomy. Outcomes after proctectomy concerning reoperation frequency and perineal wound healing are also described.

RESULTS

In total, this study included 125 patients. Proctectomy was performed in 36 patients (28.8%), of whom 14 patients (38.9%) experienced perineal wound healing problems. The rates of proctectomy were 5.6% and 32.0% 10 and 20 years after CD diagnosis, respectively. Female gender (odds ratio (OR) 3.375, 95% confidence interval (CI) 1.304-8.733, P = 0.012), disease duration (OR 1.067, 95% CI 1.011-1.126, P = 0.018) and history of perianal disease (OR 3.160, 95% CI 1.215-8.219, P = 0.018) were independent risk factors for a proctectomy procedure, whereas thiopurine medication (OR 0.170, 95% CI 0.060-0.486, P = 0.001) was an independent protective factor for proctectomy.

CONCLUSIONS

The duration of Crohn's disease, female gender and a history of perianal disease were significant risk factors for a proctectomy procedure. Future research should examine whether immunosuppressive and biological medications reduce the risk for proctectomy.

Minimally Invasive Surgery in Complex Crohn's Disease

Minimally invasive approaches are safe, feasible, and often recommended as the initial choice in the surgical management of Crohn's disease. However, a consensus has not been reached as the ideal approach in the surgical treatment of complex and recurrent Crohn's disease. Laparoscopy may provide advantages such as shorter length of stay and decreased postoperative pain and result in less adhesion formation in patients with complex disease. Robotic techniques may be beneficial in selected patients for completion proctectomy, providing better visualization in the narrow pelvis and increased dexterity. Decision of surgical technique should be made on a case-by-case basis.

Role of Fecal Diversion in Complex Crohn's Disease

Crohn's disease (CD) is a chronic inflammatory condition of the gastrointestinal tract resulting in progressive tissue damage, which can result in strictures, fistulae, and abscesses formation. The triggering mechanism is thought to be in the fecal stream, and diversion of this fecal stream is sometimes required to control disease when all other avenues of medical and surgical management have been exhausted. Fecal diversion can be temporary or permanent with the indications being defunctioning a high-risk anastomosis, as a result of a surgical complication, for disease control, or due to severe colonic, rectal, or perianal disease. The incidence of ostomy formation in CD has increased epidemiologically over time. The primary indication for ostomy formation is severe perianal fistulizing disease. However, while 64% of patients have an early clinical response after diversion for refractory perianal CD, restoration of bowel continuity is attempted in only 35% of patients, and is successful in only 17%. The current review discusses the indications for ostomy creation in complex CD, strategies for procedure selection, and patient outcomes.

Diverting Ostomy: For Whom, When, What, Where, and Why

Fecal diversion is an important tool in the surgical armamentarium. There is much controversy regarding which clinical scenarios warrant diversion. Throughout this article, we have analyzed the most recent literature and discussed the most common applications for the use of a diverting stoma. These include construction of diverting ileostomy or colostomy, ostomy for low colorectal/coloanal anastomosis, inflammatory bowel disease, diverticular disease, and obstructing colorectal cancer. We conclude the following: diverting loop ileostomy is preferred to loop colostomy, an ostomy should be used for a pelvic anastomosis < 5 to 6 cm including coloanal anastomosis and ileo-anal-pouch anastomosis, severe perianal Crohn's disease frequently requires diversion, a primary anastomosis with diverting ileostomy in the setting of diverticular perforation is safe, and a diverting stoma can be used as a bridge to primary resection in the setting of an obstructing malignancy.

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.

Crohn's Disease of the Colon, Rectum, and Anus

There is no cure for Crohn disease. Newer treatments, such as biological therapy, have led to an improved quality of life. This article focuses on the surgical management of Crohn disease of the colon, rectum, and anus. Restorative and nonrestorative surgical options for colonic Crohn disease are discussed. Treatment options for perianal Crohn disease are also reviewed.
