Recent results of laparoscopic surgery in inflammatory bowel disease

Inflammatory bowel diseases are an ideal indication for the laparoscopic surgical approach as they are basically benign diseases not requiring lymphadenectomy and extended mesenteric excision;well-established surgical procedures are available for the conventional approach.Inflammatory alterations and fragility of the bowel and mesentery,however,may demand a high level of laparoscopic experience.A broad spectrum of operations from the rather easy enterostomy formation for anal Crohn’s disease(CD)to restorati...     

Recent trends in the surgical management of inflammatory bowel disease

Surgery is required in the vast majority of patients with Crohn＇s disease （CD） and in approximately one-third of patients with ulcerative colitis （UC）. Similar to medical treatments for IBD, significant advances have occurred in surgery. Advances in CD include an emphasis upon conservatism as exemplified by more limited resections, strictureplasties, and laparoscopic resections. The use of probiotics in selected patients has improved the outcome in patients with pouchitis following restorative proctocolectomy for UC. It is anticipated that ongoing discoveries in the molecular basis of IBD will in turn identify those patients who will best respond to surgery.     

Laparoscopic-assisted bowel resections in inflammatory bowel disease: state of the art

The objectives of this paper are to review the rational, the present results and future of laparoscopic-assisted bowel surgery in patients with inflammatory bowel disease (IBD).Only a few centres in the world report on laparoscopic bowel resection in IBD that include stoma surgery, ileocolic resection, left, right and (sub)total colectomy for Crohn's disease, and subtotal or restorative total proctocolectomy (ileal pouch anal procedures).The combined series report conversion rates between 2.5% and 22.2%. Ileocolic resection, stoma creation, stricturoplasty and segmental small bowel resection are associated with an acceptable length of surgery, but laparoscopic(-assisted) total colectomy or restorative proctocolectomy still demand up to 4–6 hours of operative time. The few randomised studies addressing laparoscopic-assisted (segmental) bowel surgery versus conventional surgery demonstrated significantly less pain, a quicker return to self-care and a shorter hospital stay. The results of the series reporting on laparoscopic-assisted (ileo)colectomy in IBD are similar to those from these randomised studies. Laparoscopic-assisted subtotal colectomy and restorative proctocolectomy have no benefit compared with conventional surgery other than superior cosmesis. Morbidity of laparoscopic (ileo)colectomy in IBD is low, that of laparoscopic-assisted subtotal colectomy and restorative proctocolectomy remains to be seen.The various laparoscopic bowel resections done in IBD are all feasible. The first series describing laparoscopic surgery for IBD indicate that laparoscopic-assisted segmental (ileo)colectomy is safe and is the preferred approach provided it is done in a centre specialised in the treatment of IBD and by skilled laparoscopic surgeons beyond the learning curve. Until now, laparoscopic-assisted subtotal colectomy and restorative proctocolectomy do not have the same short-term benefits as seen in other laparoscopic colorectal procedures. Patients with inflammatory bowel disease (IBD) have a high life-time risk of having abdominal surgery and reoperations. The proposed advantages of laparoscopic surgery in this group of young patients might be higher than in patients with other colorectal diseases. Minimal physiologic insult in patients who already are under significant physiologic stress, less adhesion formation and superior cosmesis are important benefits over time. In a time where patient's demands will increase, the future of laparoscopic colonic surgery in IBD looks assured.     

Trend zur konservativen Therapie der komplizierten Sigmadivertikulitis

Currently, there is a strong trend towards conservative treatment of complicated sigmoid diverticulitis. It is based upon recent scientific knowledge on pathogenesis and course of disease. Through progress in antibiotic treatment and improvement of diagnostic procedures in many patients, it is possible to avoid emergency surgery, which is linked to a high morbidity and mortality risk. This means that surgeons can plan an elective sigmoidectomy or continue with conservative therapy. However, surgery is significant for the treatment of complicated sigmoid diverticulitis as a result of the extension towards minimally invasive procedures. In the case of free perforation, the operation is still considered the gold standard. Laparoscopic lavage and drainage offers a new therapeutic option for purulent peritonitis. Also, in sigma resection, a minimally invasive approach is clearly established. According to the German guidelines for diverticulosis/diverticulitis, laparoscopic sigma resection is the treatment of choice for elective surgery.     

Surgical treatment of inflammatory bowel diseases and pregnancy

Ulcerative colitis (UC) and Crohn's disease (CD) affect women of reproductive age. Surgical intervention is often required. Therefore, the implications of disease treatment and pregnancy need to be understood. The standard surgery for UC is proctocolectomy, followed by ileal pouch anal anastomosis (IPAA). This review summarises the literature describing the effects of IPAA on gynaecologic and sexual health, fertility, pregnancy, labour and delivery. The emerging role of laparoscopic IPAA and the limited role of ileo-rectal anastomosis (IRA) are discussed. The experience with emergency surgery in pregnant women with ulcerative colitis is also presented. The literature explores two key issues of pregnancy in CD: the possible effect of pregnancy decreasing resection rates, and the optimal mode of delivery, especially in the setting of perianal CD. These two issues together with the available literature describing stoma function during pregnancy and the foetal outcome after surgical therapy are presented.     

Minimally invasive approaches for the treatment of inflammatory bowel disease

Despite significant improvements in medical management of inflammatory bowel disease, many of these patients still require surgery at some point in the course of their disease. Their young age and poor general conditions, worsened by the aggressive medical treatments, make minimally invasive approaches particularly enticing to this patient population. However, the typical inflammatory changes that characterize these diseases have hindered wide diffusion of laparoscopy in this setting, currently mostly pursued in high-volume referral centers, despite accumulating evidences in the literature supporting the benefits of minimally invasive surgery. The largest body of evidence currently available for terminal ileal Crohn’s disease shows improved short term outcomes after laparoscopic surgery, with prolonged operative times. For Crohn’s colitis, high quality evidence supporting laparoscopic surgery is lacking. Encouraging preliminary results have been obtained with the adoption of laparoscopic restorative total proctocolectomy for the treatment of ulcerative colitis. A consensus about patients’ selection and the need for staging has not been reached yet. Despite the lack of conclusive evidence, a wave of enthusiasm is pushing towards less invasive strategies, to further minimize surgical trauma, with single incision laparoscopic surgery being the most realistic future development.     

Ileoanal pouch-related fistulae: A systematic review with meta-analysis on incidence,treatment options and outcomes

BackgroundIleoanal pouch related fistulae (PRF) are a complication of restorative proctocolectomy often requiring repeated surgical interventions and with a high risk of long-term recurrence and pouch failure.AimsTo assess the incidence of PRF and to report on the outcomes of available surgical treatments.MethodsA PRISMA-compliant systematic literature search for articles reporting on PRF in patients with inflammatory bowel diseases (IBD) or familial adenomatous polyposis (FAP) from 1985 to 2020.Results34 studies comprising 770 patients with PRF after ileal-pouch anal anastomosis (IPAA) were included. Incidence of PRF was 1.5-12%. In IBD patients Crohn's Disease (CD) was responsible for one every four pouch-vaginal fistulae (PVF) (OR 24.7; p=0.001). The overall fistula recurrence was 49.4%; procedure-specific recurrence was: repeat IPAA (OR 42.1; GRADE +); transvaginal repair (OR 52.3; GRADE ++) and transanal ileal pouch advancement flap (OR 56.9; GRADE ++). The overall failure rate was 19%: pouch excision (OR 0.20; GRADE ++); persistence of diverting stoma (OR 0.13; GRADE +) and persistent fistula (OR 0.18; GRADE +).ConclusionPVFs are more frequent compared to other types of PRF and are often associated to CD; surgical treatment has a risk of 50% recurrence. Repeat IPAA is the best surgical approach with a 42.1% recurrence rate.

Laparoscopic restorative proctocolectomy with ileal pouch-anal anastomosis for Peutz-Jeghers syndrome with synchronous rectal cancer

We report on a patient diagnosed with PeutzJeghers syndrome(PJS) with synchronous rectal cancer who was treated with laparoscopic restorative proctocolectomy with ileal pouch-anal anastomosis(IPAA). PJS is an autosomal dominant syndrome characterized by multiple hamartomatous polyps in the gastrointestinal tract, mucocutaneous pigmentation, and increased risks of gastrointestinal and nongastrointestinal cancer. This report presents a patient with a 20-year history of intermittent bloody stool, mucocutaneous pigmentation and a family history of PJS, which together led to a diagnosis of PJS. Moreover, colonoscopy and biopsy revealed the presence of multiple serried giant pedunculated polyps and rectal adenocarcinoma. Currently, few options exist for the therapeutic management of PJS with synchronous rectal cancer. For this case, we adopted an unconventional surgical strategy and ultimately performed laparoscopic restorative proctocolectomy with IPAA. This procedure is widely considered to be the first-line treatment option for patients with ulcerative colitis or familial adenomatous polyposis. However, there are no previous reports of treating PJS patients with laparoscopic IPAA. Since the operation, the patient has experienced no further episodes of gastrointestinal bleeding and has demonstrated satisfactory bowel control. Laparoscopic restorative proctocolectomy with IPAA may be a safe and effective treatment for patients with PJS with synchronous rectal cancer.     

Diagnosis and treatment of ileal pouch diseases in patients with underlying ulcerative colitis

Opinion statement Ileal pouch-anal anastomosis (IPAA) after total proctocolectomy is the surgical treatment of choice for ulcerative colitis (UC) patients with medically refractory disease or dysplasia. IPAA significantly improves quality of life in UC patients who require surgery. However, certain inflammatory and noninflammatory diseases can develop after the surgery, including pouchitis, Crohn’s disease (CD) of the pouch, cuffitis, and irritable pouch syndrome. The cause and pathogenesis of these disease conditions of IPAA are largely unknown. Accurate diagnosis and classification are important for appropriate management.     

Long-term results of ileal pouch-anal anastomosis in Crohn's disease

The unexpected diagnosis of Crohn's disease (CD) after restorative proctocolectomy is a relatively frequent occurrence. We report a retrospective analysis of the long-term development of patients with an ileal pouch-anal anastomosis (IPAA) in whom the definitive anatomopathological diagnosis was CD, and compare their development with that of patients in whom the diagnosis of ulcerative colitis (UC) was confirmed. We reviewed the clinical data of 112 patients with an IPAA. The definitive diagnosis was CD in 12, and UC in the rest. The mean follow-up period was 76 months (range 12 to 192). We analyzed and compared the epidemiologic and clinical data, postoperative complications, functional results, anxiety, and quality of life in the two groups. Postoperative morbidity and the degree of satisfaction were similar in the two groups. The test showed a lower level of anxiety and higher quality of life in patients with CD. Of all the functional parameters studied, only urgency of defecation presented a higher risk in the CD group (HR: 4.13, CI: 1.41-12.04, p = 0.027). Despite the fact that a diagnosis of CD is currently considered a contraindication for an IPAA, some patients with secondary diagnosis of CD have good functional outcome and quality of life after restorative proctocolectomy. Closure of the temporary ileostomy may be justified in these patients.     

Neoplasia in the ileoanal pouch following colectomy in patients with ulcerative colitis and primary sclerosing cholangitis

Background & AimsPrimary sclerosing cholangitis (PSC) is typically associated with inflammatory bowel disease (IBD), particularly ulcerative colitis (UC). PSC–IBD patients are at an increased risk for colorectal neoplasia. The ileal pouch-anal anastomosis (IPAA) is a treatment option for patients with medically refractory UC or neoplasia. However, little is known about the development of pouch neoplasia in PSC–UC patients following an IPAA. We aim to describe the incidence of pouch neoplasia in PSC–UC patients after an IPAA.MethodsWe conducted a retrospective chart review of patients with a confirmed diagnosis of PSC and IBD who underwent colectomy with IPAA followed by pouch surveillance between 1995 and 2012.ResultsSixty-five patients were included in the cohort and were followed up from the time of colectomy/IPAA for a median of 6 years. The most common indications for surgery were low-grade dysplasia (LGD) and refractory colitis. Only 3 patients developed evidence of neoplasia (LGD n = 1, high-grade dysplasia n = 1, adenocarcinoma n = 1). The cumulative 5-year incidence of pouch neoplasia was 5.6% (95% confidence intervals [CI], 1.8%–16.1%).ConclusionBased on our short-term follow-up, surveying the pouch frequently appears to be an unnecessary practice in PSC–IBD patients. Longer follow-up will be needed to develop an optimal surveillance strategy for the development of dysplasia and cancer in such patients.     

An analysis of an inflammatory bowel disease practice in an urban community hospital.

OBJECTIVES: To review an individual community gastroenterologist's experience with inflammatory bowel disease (IBD). The aspects studied were distribution of disease, need for hospital admission, immunosuppressants, systemic steroids, and surgery and its indications. The incidence of cancer was also reviewed. PATIENTS AND METHODS: The charts of all IBD patients (n=373) seen between 1993 and 1996 by an individual gastroenterologist in an urban community hospital were reviewed for the aforementioned information. Patients seen during this period may have been diagnosed with IBD before or during the period of 1993 to 1996. RESULTS: Of the 373 patients, 219 had Crohn's disease (CD) and 154 had ulcerative colitis (UC). The most common age of onset for both groups was 20 to 29 years. Distal UC and distal Crohn's colitis patients rarely required surgery, hospitalization, systemic steroids or immunosuppressants. Eighty per cent of patients with small bowel CD and 51% of those with ileocolonic CD required at least one operation. Of the UC patients, 10.4% required surgery. Of the UC patients undergoing surveillance for cancer, none developed cancer but one developed significant dysplasia. CONCLUSIONS: In both CD and UC the site of the inflammation plays a major role in determining the need for hospitalization, surgery, systemic steroids and immunosuppressants. Distal UC, the most common form of UC in this group of patients, is a very benign disease. Of all forms of IBD, small bowel CD had the greatest need for hospitalization, surgery and systemic steroids.     

Old-age inflammatory bowel disease onset：A different problem？

Inflammatory bowel disease (IBD) in patients aged > 60 accounts for 10%-15% of cases of the disease. Diganostic methods are the same as for other age groups. Care has to be taken to distinguish an IBD colitis from other forms of colitis that can mimick clinically, endoscopically and even histologically the IBD entity. The clinical pattern in ulcerative colitis (UC) is proctitis and left-sided UC, while granulomatous colitis with an inflammatory pattern is more common in Crohn’s disease (CD). The treatment o...     

Long-term evolution and predictive factors of mild inflammatory bowel disease

Background Crohn’s disease (CD) and ulcerative colitis (UC) are potentially progressive diseases. Few data are available on the prevalence and the factors associated with mild inflammatory bowel diseases (IBD). Aim Our aim was to assess the natural history of mild CD and mild UC and to identify predictive factors of mild evolution over the long term. Methods Retrospective study of IBD patients registered in the database of the university hospital CHU of Liège, Belgium. Mild CD was defined as an inflammatory luminal disease (no stricture, abdominal or perianal fistulae) requiring no immunomodulator (IM), anti-TNF and no surgery. Mild UC was defined as no requirement for IM, anti-TNF and no colectomy. Results Four hundred and seventy-three CD and 189 UC were included (median follow-up: 13 and 11 years respectively). At 1 year, 147 patients had mild CD. At 5 years and the maximum follow-up, 56% and 13% patients still had mild CD, respectively. At 1 year, 142 patients had mild UC. At 5 years and the maximum follow-up, 72% and 44% still had a mild UC, respectively. Factors associated with long-term mild CD and UC were older age at diagnosis and absence of corticosteroids in the first year. In UC proctitis location was associated with mild UC. Conclusions In this cohort, 90% of CD patients and 3/4 of UC with mild disease at 1 year lost their mild disease status over time. An old age at diagnosis was predictive of the persistence of a mild CD and UC.     

Serologic antiglycan antibodies in inflammatory bowel disease

At diagnosis, the clinical presentation of both entities of inflammatory bowel disease (IBD), Crohn's disease (CD) and ulcerative colitis (UC), can be highly heterogeneous, leading to a delay in correct identification or differentiation between CD and UC in a subgroup of patients. In addition, the natural history of IBD patients is strikingly variable. During the life of a CD patient, in the majority of instances, stricturing or perforating complications occur, leading to surgery. Serologic antiglycan antibodies directed against various microbial carbohydrate epitopes are useful in differentiation of CD vs. UC and are a promising tool for identification of CD patients at risk for rapid progression and need for surgical intervention. Instruments for prediction of CD behavior are critical, as the use of immunomodulators and/or biologicals early in the disease course might be justified for patients with a high hazard for complicated disease behavior.     

Significant Differences Between Crohn’s Disease and Ulcerative Colitis Regarding the Impact of Body Mass Index and Initial Disease Activity on Responsiveness to Azathioprine: Results from a European Multicenter Study in 1,176 Patients

In a survey comprising 1,176 patients with inflammatory bowel disease (IBD) we recently showed that azathioprine (AZA) beyond 4 years is beneficial in ulcerative colitis (UC) patients and in a subset of Crohn’s disease (CD) patients. Here, we show for the first time that azathioprine responsiveness depends on body mass index (BMI). The relationship is reciprocal in UC and CD, with a better outcome in UC patients with a BMI<25 and in CD patients with a BMI>25. These observations are particularly interesting considering the evolving concept of a relationship between fatty metabolism and immune regulation. Additionally, we show that CD patients, but not UC patients, respond better to AZA when it is started in clinical remission. This observation may support data favouring a “hit hard and early” regime in CD. Finally, we were able to demonstrate a decrease in the incidence of CD-related complications requiring surgery through treatment with AZA.     

New serological markers in pediatric patients with inflammatory bowel disease

The spectrum of serological markers associated with inflammatory bowel disease(IBD)is rapidly growing.Due to frequently delayed or missed diagnoses,the application of non-invasive diagnostic tests for IBD,as well as differentiation between ulcerative colitis(UC)and Crohn’s disease(CD),would be useful in the pediatric population.In addition,the combination of pancreatic autoantibodies and antibodies against Saccharomyces cerevisiae antibodies/perinuclear cytoplasmic antibody(pANCA)improved the sensitivity of serological markers in pediatric patients with CD and UC.Some studies suggested that age-associated differences in the patterns of antibodies may be present,particularly in the youngest children.In CD,most patients develop stricturing or perforating complications,and a significant numberof patients undergo surgery during the disease course.Based on recent knowledge,serum antibodies are qualitatively and quantitatively associated with complicated CD behavior and CD-related surgery.Pediatric UC is characterized by extensive colitis and a high rate of colectomy.In patients with UC,high levels of antiCBir1 and pANCA are associated with the development of pouchitis after ileal pouch-anal anastomosis.Thus,serologic markers for IBD can be applied to stratify IBD patients into more homogeneous subgroups with respect to disease progression.In conclusion,identification of patients at an increased risk of rapid disease progression is of great interest,as the application of early and more aggressive pharmaceutical intervention could have the potential to alter the natural history of IBD,and reduce complications and hospitalizations.     

The potential benefits and disadvantages of laparoscopic surgery for ulcerative colitis: A review of current evidence

Up to 35% of patients with ulcerative colitis will require surgery during the course of their disease. Nowadays, a total colectomy with ileal pouch-anal anastomosis is the preferred procedure, which can be performed open or via laparoscopic approach. Since the early '90s, minimally invasive techniques have gained popularity, but the extend of restorative procedures in these patients has restricted the use of laparoscopic approaches mainly to elective procedures in specialised centres. This review discusses the benefits and disadvantages of laparoscopic surgery when compared to open surgery. It presents the current evidence on short-term and long-term post-operative results, functional outcome, fecundity, and costs, for both elective and emergency indications. In addition, the value of new techniques (including single port surgery) and alternative laparoscopic approaches (e.g. ileo-rectal anastomosis, Kock-pouch and appendectomy) will be discussed.
