Abstract
Proctocolectomy with ileal J‑pouch-anal and rectal reconstruction is the standard surgical treatment for ulcerative colitis, selected cases of Crohn's disease, FAP and multilocular colon carcinoma. Although this treatment has been continuously developed over the last 40 years, the long-term success rate is 80-90% of the treated patients. The reasons for this are manifold: chronic pouchitis, incontinence, secondary diagnosis of Crohn's disease, fistulas, severe surgical complications, rectal stump left for too long, chronic abscess and surgical technical errors. This article deals with the control of acute complications and with the management of long-term complications. Some of the triggering complications for pouch failure do not generally imply failure of the method. A correction, closure of the fistula and in individual cases also a completely new pouch creation can restore a good pouch function in about 75% of cases. Various indications, techniques and results are presented.

Abstract
BACKGROUND AND AIMS Carcinoma associated with perianal fistula in Crohn's disease is a pending threat for patients. This study aimed to improve understanding and facilitate development of diagnostic and therapeutic strategies. METHODS A retrospective case-control study was conducted at four German hospitals. The analysis included 40 patients with proven malignancy associated with perianal Crohn's fistulas and 40 randomly selected controls with fistulizing perianal Crohn's disease. Differences between groups were analysed and multivariate calculations were performed to describe risk factors for oncological outcomes. RESULTS Histology revealed adenocarcinoma in 33/40 patients and squamous cell carcinoma in 7/40 patients. Compared to fistula patients without carcinoma, patients with malignancies associated with fistula had a diagnosis of Crohn's disease at younger age. Crohn's disease lasted longer in patients with malignancy [25.8 ± 9.0 vs 19.6 ± 10.4; p = 0.006]. Fistula-related findings differed significantly between the two groups. Signs of complicated and severe fistulation including complex anatomy and chronic activity occurred significantly more often in patients with malignancy associated with fistula. Significant multivariate hazard ratios for overall mortality and progression-free survival were shown for histological type of cancer, metastatic disease and R1 resection. Overall survival was 45.1 ± 28.6 months and the 5-year survival rate was 65%. CONCLUSIONS In patients with adenocarcinoma or squamous cell carcinoma associated with perianal fistula in Crohn's disease, fistula characteristics determine the risk of malignancy. Early diagnosis influences outcomes, while treatment of chronic fistula activity may be key to preventing malignancy. Expert multimodal therapy is paramount for successful treatment of perianal fistula-associated malignancies.

Abstract
Early surgery is a very important aspect of treatment of inflammatory bowel diseases. In Crohn's disease, early surgery should be performed in emergencies, in refractory courses, and in special cases at the beginning of the disease if there is a stenosis limited to the terminal ileum. In ulcerative colitis, prolonged therapy with extended application of all available substances should be avoided. Every therapy with more than 2 biologicals endangers the patient. Low-grade intraepithelial neoplasia (IEN) should also be resected earlier due to a 23% risk of synchronous and metachronous high-grade IEN or cancer.

Abstract
BACKGROUND Severe courses of Crohn's disease (CD) during pregnancy are rare. However, if occurring, the risk of miscarriage and low birth weight is increased. At present, only limited data is available on the treatment of CD during pregnancy. In particular, there are no standard guidelines for surgical therapy. Nevertheless, surgery is often unavoidable if complications during the course of the disease arise. PURPOSE This study provides a critical overview of conventional and interventional treatment options for CD complications during pregnancy and analyses the surgical experience gained thus far. For illustrative purposes, clinical cases of three young women with a severe clinical course during pregnancy are presented. METHODS After treatment-refractory for conservative and interventional measures, surgery remained as the only treatment option. In all cases, a split stoma was created after resection to avoid anastomotic leaks that would endanger the lives of mother and child. The postoperative course of all three patients was uneventful, and pregnancy remained intact until delivery. No further CD specific medication was required before birth. CONCLUSIONS The management of CD patients during pregnancy requires close interdisciplinary co-operation between gastroenterologists, obstetricians, anaesthetists and visceral surgeons. For the protection of mother and child treatment should thus be delivered in a specialised centre. This article demonstrates the advantages of surgical therapy by focusing on alleviating CD complaints and preventing postoperative complications.

Abstract
Conservative treatment of fecal incontinence and obstructive defecation can be treated by many conservative treatment modalities. This article presents the options of medication therapy, spincter exercises, electric stimulation, transcutaneous tibial nerve stimulation, anal irrigation and injection of bulking agents. These methods are presented with reference to the currently available literature but the evidence-based data level for all methods is low. For minor disorders of anorectal function these conservative methods can lead to an improvement of anorectal function and should be individually adapted.

Abstract
OBJECTIVE Effects of immune cells on the beta 2 (β2)-defensin (HBD2) expression and its antibacterial activity in the intestinal mucosa of patients with inflammatory bowel diseases remains unclear. The small size of these proteins presents a major challenge in localizing antibacterial activities in human intestinal tissue. In this study, we evaluated the detection limits at mRNA and protein level by approaching HBD2 from small tissue samples. METHODS HT-29 colonic epithelial cells were incubated with proinflammatory cytokines before HBD2 mRNA was investigated by quantitative polymerase chain reaction. The HBD2 protein was assessed by Western blot analysis using HBD2 fused with enhanced green fluorescent protein (HBD2-EGFP). Purified HBD2 fused with the glutathione-S-transferase (GST-HBD2) was used to detect antibacterial activity in a densitometric assay. RESULTS Interleukin (IL)-1β induced HBD2 mRNA in HT-29 cells; however, tumor necrosis factor-α, IL-6 and IL-17 did not. The Western blot had a sensitivity of 1.5 pmol to detect recombinant HBD2, but did not detect HBD2 in either human intestinal or IL-1β-treated HT-29 cells. HBD2-EGFP was detected by HBD2-specific Western blot within cell lysates and culture supernants of transfected HT-29 and primary cells. In nanomolar ranges, GST-HBD2 reduced bacterial growth. The HBD2 bioactivity depended on solution conditions, but not on the size of the fusion partner. CONCLUSION The established fusion proteins provide excellent tools to evaluate expression patterns and antibacterial effects of HBD2 in human intestinal tissue samples.

Abstract
BACKGROUND The pathophysiology of rectal prolapse and intussusception has not yet been clarified. This is reflected in the multiplicity of surgical procedures. The aim of this prospective study was to measure morphological and functional changes of the pelvic floor and the rectum before and after resection rectopexy. METHODS A total of 21 patients (mean age 60 years; 2 men, 19 women) with manifest rectal prolapse and rectoanal intussusception underwent sigmoidectomy and rectopexy with an absorbable polyglactin mesh graft. The following analyses were performed preoperatively and, on average, 15 months (range 6-21 month) postoperatively: radiologic defecography, rectal volumetry, sphincter manometry, and evaluation of clinical symptoms. RESULTS Postoperatively there was no patient with rectal prolapse, and only one with an intussusception. Rectal compliance increased from 6.4 to 10.2 ml/mmHg. Rectal volumetry showed a decrease of the thresholds for the sensation of "desire to defecate" and "maximal tolerated volume" (100-75 ml, 175-150 ml). Postoperatively, there was a higher level of the pelvic floor during contraction. The anorectal angle, vector volume, radial asymmetry, sphincter length, and resting and squeezing pressures were unchanged. Surgery improved rectal evacuation (p = 0.03), continence (p = 0.01), stool consistency (p = 0.03), and warning period (p = 0.01). Patients' personal assessment showed an improved overall satisfaction. CONCLUSIONS Resection rectopexy is a reliable method for treating rectal prolapse and rectoanal intussusception with clear improvement of the patient's clinical symptoms. The restored anorectal function can be attributed to improved rectal compliance, a lower sensory threshold, an elevation of the pelvic floor during squeezing, and an improved rectal evacuation.

Abstract
BACKGROUND Proctocolectomy with ileal pouch-anal anastomosis (IPAA) is a surgical approach for ulcerative colitis and familial adenomatous polyposis. This study evaluated predictors of the need for a permanent ileostomy to identify patients at high risk of IPAA failure. METHODS This was a retrospective analysis of patients who underwent proctocolectomy and IPAA between 1997 and 2008. A logistic regression model was used for multivariable analysis of potential risk factors. RESULTS Proctocolectomy was combined with IPAA in 185 patients, of whom 169 had a loop ileostomy formed. IPAA and ileostomy closure were successful in 162 patients (87.6 per cent). Reasons for not closing the ileostomy included pouch failure (16 patients), patient choice (5) and death (2). Thus one in eight patients had a permanent ileostomy after planned IPAA. Age was the major predictor of the need for a permanent ileostomy in multivariable analysis (P = 0.002) with a probability of more than 25 per cent in patients aged over 60 years. However, advancing age was associated with colitis, co-morbidity, obesity and corticosteroid use. CONCLUSION The probability of the need for a permanent ileostomy after IPAA increases with age.

Abstract
BACKGROUND AND AIMS The etiology of pouchitis after coloproctomucosectomy with ileal pouch-anal anastomosis in patients with ulcerative colitis is still unknown. Beside changes in luminal antigens, the immunological predisposition is assumed to be responsible. In previous electrophysiological studies, we showed that mucosal barrier and transport function in pouchitis is markedly reduced. Thus, the aim of the present study was to analyze barrier function on the molecular level. MATERIAL AND METHODS Pouch biopsies of 36 ulcerative colitis patients were analyzed. Time points were (1) intraoperative immediately prior to ileal pouch-anal anastomosis (n = 13), (2) >1 year after ileostomy closure (pouch, n = 12), and (3) during pouchitis (n = 11). Control terminal ileum biopsies were obtained from eight patients undergoing hemicolectomy due to carcinoma. Expression of tight junction proteins was analyzed by Western blotting and confocal laser-scanning microscopy. To elucidate effects on epithelial barrier properties, impedance spectroscopy was performed in miniaturized Ussing chambers. RESULTS In pouchitis, epithelial resistance was markedly reduced compared to non-inflamed pouch and control ileum. Expression of tight junction proteins claudin-1, 3, 4, 5, and 7 and occludin revealed differential expression regulation with the tightening tight junction protein claudin-1 being decreased and an increase of the pore-forming claudin-2, whereas other claudins remained constant. Morphometry indicated the mucosal surface to be unchanged. CONCLUSION Pouchitis is characterized by a selective change of tight junction proteins in favor of opening the epithelial tight junction and, thus, the paracellular pathway, which contributes to the inflammatory process. This resembles changes in inflammatory bowel disease (IBD) and indicates IBD recurrence in pouchitis.

Abstract
PURPOSE The staging of anal cancer is extremely important for therapy and prognosis. Transanal endoscopic ultrasound and magnetic resonance imaging are routinely applied. The aim of this prospective comparative study is to evaluate whether tumor staging is concordant between these techniques. METHODS Forty-five anal cancer patients underwent endoscopic ultrasound and magnetic resonance imaging. Histological confirmation was obtained in all patients. The two test methods were compared with the kappa concordance index and sensitivity for the initial method of tumor detection was calculated. For six patients who were operated upon because of tumor progression, the results were evaluated against the histological tumor stage. RESULTS High concordance was found in the assessment of tumor size and nodal status (kappa index 0.63 and 0.77). Cancer patients were correctly identified with 100% sensitivity (45/45) by endoscopic ultrasound and with 88.9% (40/45) sensitivity by magnetic resonance imaging. In the six operated patients, T stage was correctly assessed in four of six patients by endoscopic ultrasound and in three of six patients by magnetic resonance imaging. CONCLUSION The results of endoscopic ultrasound strongly coincide with those of magnetic resonance imaging. Endoscopic ultrasound may be superior to magnetic resonance imaging for detection of small superficial tumors. However, magnetic resonance imaging is needed for N staging.

Abstract
OBJECTIVE Backwash ileitis (BI) has not been identified as a risk factor for pouchitis. The aim of this study was to investigate the barrier function of the ileoanal pouch depending on the presence of BI. The incidence of pouchitis in a population of ulcerative colitis patients with BI is also reported. MATERIAL AND METHODS Biopsies were taken from 80 patients with ulcerative colitis: a) terminal ileum prior to pouch creation (pre-IAP); b) 16 months after ileostomy closure (intact pouch); and c) during pouchitis. Patients were stratified into the BI group and the non-BI (ØBI) group. Barrier function was determined in Ussing-chambers as epithelial resistance by impedance analysis and as mannitol permeability from (3)H-mannitol fluxes. Na(+)-glucose co-transport was measured as a change in short-circuit current (I(SC)) after addition of glucose. Relative risk of developing pouchitis was calculated by corrected chi(2) test. RESULTS In 13/21 (BI/ØBI) pre-IAP patients, 23/37 (BI/ØBI) with an intact pouch, and 35/7 (BI/ØBI) with pouchitis, epithelial resistance in BI/ØBI was 13.5+/-1.6/14.3+/-0.9 Omega.cm(2) for pre-IAP, 12.7+/-1.3/16.8+/-1.2 Omega x cm(2) (p<0.05 BI versus ØBI) for the intact pouch, and 10.1+/-1.1/9.9+/-1.8 Omega x cm(2) for pouchitis (p<0.05 BI versus ØBI with an intact pouch). No differences were found for electrogenic chloride secretion and active Na(+)-glucose co-transport between BI/ØBI in the three groups. In patients with BI, pouchitis was more common (35 versus 7 patients, odds ratio 33.0 (95% CI 8.3-143.9; p<0.0001)). CONCLUSIONS Ulcerative colitis patients with BI show impaired barrier function in the further course of the ileoanal pouch. Thus, BI has a long-term impact on epithelial barrier function.

Abstract
BACKGROUND/AIMS About half of all Crohn's disease (CD) patients undergo surgery at some point, many because of strictures. An alternative possibility is to dilate strictures endoscopically. However, little is known about prognostic factors. PATIENTS AND METHODS Thirty-two patients with primary CD (n=2), radiogenic strictures (n=1), or postoperative strictures (27 because of CD; 2 after resection because of cancer), were planned to undergo colonoscopic dilatation of which 25 patients were dilated (10 men; 15 women; median age 48). Length of stenosis, diameter of stricture, balloon size, smoking status, ulcer in the stricture, passage postdilatation, hemoglobin level, complications, redilatation, and subsequent surgery were recorded. Only patients with at least 6 months follow up were included. RESULTS Five out of 32 patients had no stenosis, marked inflammation, or fistulas adjacent to the stricture. One patient each had a long stricture (8 cm) or a filiform stenosis ruling out dilatation [technical success, 25/27 (92.6%)]. Among these 25 patients, 39 colonoscopies with 51 dilatations were performed. After a single dilatation, 52% were asymptomatic while 48% needed another intervention, half of them surgery. Bleeding without need for transfusion occurred in 3 out of 39 colonoscopies and one perforation required surgery. Significant prognostic factors were smoking and ulcers in the stricture (P<0.05 each). Some ulcers led to intussusception requiring surgery in spite of good dilatation results. CONCLUSION Through the endoscope balloon stricture dilatation is a relatively safe and often effective treatment modality in ileocolonic strictures. The presence of ulcers in the stricture have a worse outcome as do smokers.

Abstract
The optimization of surgical techniques has made it possible to now treat patients with deep-seated rectal cancer by performing deep anterior rectal resection with coloanal anastomosis while avoiding a permanent stoma. To prevent a high bowel movement frequency and limited continence with an imperative need to empty the bowel, the coloanal pouch operation was developed to construct a rectal substitute. Nowadays, patients with ulcerative colitis or familial adenomatous polyposis of the colon undergo proctocolectomy as the definitive treatment for their underlying disease. Continuity is restored by creating an ileoanal reservoir. This contribution describes the surgical indications and pathophysiological changes for the colon J-pouch and ileoanal reservoir. In addition, explanations of the surgical techniques for both procedures are presented. The functional results are compared with those of other reconstruction options and discussed, taking our own results into consideration.

Abstract
Total mesorectal excision (TME) has become the recommended method for treatment of cancer in the middle or lower third of the rectum. Thus very low anastomoses are necessary to preserve continence, and pouch reconstruction is favored. It is unclear whether the level of anastomosis is important for continence and quality of life in colonic J-pouch reconstruction. In this investigation all patients were included who underwent curative elective anterior continuity resection with colorectal or coloanal J-pouch reconstruction for primary rectal cancer between January 2001 and December 2004. Exclusion criteria were distant metastases and any signs of recurrence at the time of investigation. Evaluation of continence performance by Wexner and Holschneider questionnaire and quality of life using the QLQ-C30 and QLQ-CR38 (EORTC) questionnaires was done 220 +/- 38 days after closure of the protective Ileostomy, which was performed 106 +/- 48 days after primary intervention. Fifty-two patients (79%) were analyzed. Colopouch rectal anastomosis was performed in eighteen cases and colopouch anal anastomosis in thirty-four cases. Fifty percent of the patients in both groups were continent for solid stool. Patients with a colopouch anal anastomosis had a significantly higher rate of incontinence for liquid stool, however. They took stool-regulating medicine more frequently and complained of fecal soiling and a restricted quality of life. Patients with a colopouch anal anastomosis had a significantly lower score on the most important points of the QLQ-C30 (emotional functioning, social functioning, pain, and quality of life). The same applied to the QLQ-CR38 for body image and problems with defecation. The quality of life of patients with a colopouch anal anastomosis was still considered acceptable compared with reference data for the normal healthy population, however. Both continence and quality of life are substantially affected by the level of the anastomosis after colonic pouch reconstruction. This suggests preservation of a small part of the rectum when oncologically feasible and performing a colopouch rectal anastomosis.

Abstract
BACKGROUND Epithelial barrier function is impaired in Crohn's disease. AIM To define the underlying cellular mechanisms with special attention to tight junctions. METHODS Biopsy specimens from the sigmoid colon of patients with mild to moderately active or inactive Crohn's disease were studied in Ussing chambers, and barrier function was determined by impedance analysis and conductance scanning. Tight junction structure was analysed by freeze fracture electron microscopy, and tight junction proteins were investigated immunohistochemically by confocal laser scanning microscopy and quantified in immunoblots. Epithelial apoptosis was analysed in terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick-end labelling and 4',6-diamidino-2-phenylindole staining. RESULTS Patients with active Crohn's disease showed an impaired intestinal barrier function as indicated by a distinct reduction in epithelial resistance. As distribution of conductivity was even, focal epithelial lesions (eg, microerosions) did not contribute to barrier dysfunction. Instead, freeze fracture electron microscopy analysis showed reduced and discontinuous tight junction strands. Occludin and the sealing tight junction proteins claudin 5 and claudin 8 were downregulated and redistributed off the tight junction, whereas the pore-forming tight junctions protein claudin 2 was strongly upregulated, which constitute the molecular basis of tight junction changes. Other claudins were unchanged (claudins 1, 4 and 7) or not detectable in sigmoid colon (claudins 11, 12, 14, 15 and 16). Claudin 2 upregulation was less pronounced in active Crohn's disease compared with active ulcerative colitis and was inducible by tumour necrosis factor alpha. As a second source of impaired barrier function, epithelial apoptosis was distinctly increased in active Crohn's disease (mean (SD) 5.2 (0.5)% v 1.9 (0.2)% in control). By contrast, barrier function, tight junction proteins and apoptosis were unaffected in Crohn's disease in remission. CONCLUSION Upregulation of pore-forming claudin 2 and downregulation and redistribution of sealing claudins 5 and 8 lead to altered tight junction structure and pronounced barrier dysfunction already in mild to moderately active Crohn's disease.

Abstract
BACKGROUND AND AIMS Bacterial overgrowth appears to play an important role in the pathogenesis of ileoanal pouches. Therefore, the capability of bacterial permeation and its determinants is of great interest. The aim of this study was to examine bacterial permeation in the ileoanal pouch and to correlate the results with the degree of inflammation, the epithelial resistance, the mucosal transport function, and the age of the ileoanal pouches. MATERIALS AND METHODS Biopsies were taken from 54 patients before colectomy (n = 13; preileal pouch-anal anastomosis [IPAA]), and closure of ileostomy (n = 7; deviation), <1 year after closure of ileostomy (n = 8; intact pouch I), >1 year after closure of ileostomy (n = 16; intact pouch II), in the case of pouchitis (n = 11), and in 11 controls. Tissues were mounted in a miniaturized Ussing chamber. Escherichia coli was added to the mucosal side of the Ussing chamber, and the permeation was proven by serosal presence of E. coli. Epithelial and subepithelial resistance was determined by transmural impedance analysis. Active Na-glucose cotransport and active Cl secretion were measured. Specimens were analyzed by fluorescent in situ hybridization with oligonucleotide probes targeting the bacterial 16s ribosomal RNA. The bacteria in and on the tissue were enumerated. RESULTS Bacterial permeation occurred in 2 of 13 pre-IPAA, 2 of 7 deviations, 0 of 8 intact pouch I, 9 of 16 intact pouch II, 5 of 11 pouchitis specimens, and 0 of 11 ileum controls. The frequency of bacterial permeation in the intact pouch II group is higher than in the intact pouch I group (P < 0.001). Epithelial resistance, mannitol fluxes, electrogenic chloride secretion, sodium-glucose cotransport of the bacterially permeated specimens versus nonpermeated of the intact pouch II group, and the pouchitis group and subepithelial resistance remained unchanged. Intramural bacteria could be detected by fluorescence in situ hybridization mainly in long-lasting pouches, but there was no correlation with bacterial permeation. CONCLUSIONS The long-lasting ileoanal pouch is associated with increased bacterial permeability. This is not correlated with a disturbed function of the pouch mucosa but could be a precursor of pouchitis.

Abstract
BACKGROUND In about 10 % of all patients with colorectal cancer, the primary invention already discloses adhesions or infiltration of adjacent organs. En bloc resection of the tumor-bearing bowel segment with adjacent organs is done to give patients a chance for curation, since intraoperative differentiation is not possible. The aim of this study is characterization of the patient population as well as evaluation of the morbidity and mortality associated with this type of extensive intervention. METHOD Between 1/95 and 6/04, we analyzed all patients with progressive primary colorectal cancer, who underwent multivisceral surgery with en bloc resection of at least one other organ. The target parameters were tumor characteristics as well as postoperative morbidity and mortality. RESULTS A total of 1 001 patients with colorectal cancer underwent surgery. 101 patients (10 %) required multivisceral resection. In 17 % the indication was exigent. About 70 % of the interventions involved the colon. Tumor perforation was seen in 17 % of patients with colon cancer and 16 % with rectal cancer. Resection of the inner genitals was most frequent in both colon and rectal cancer (26 and 84 %) followed by small bowel resection (21 %) and partial bladder resection (19 %). Other organs play a secondary role in rectal cancer while partial bladder resection (20 %) and abdominal wall resection (14 %) is observed more frequently in colon cancer. Resection of parenchymatous organs (kidney, suprarenal gland, spleen, pancreas, liver) and others like the stomach is quite rare in colon cancer. Actual tumor infiltration (T4 situation) was observed in 51 % of patients with colon cancer and in 64 % of those with rectal cancer. Local R0 resection (97 vs. 96 %) was successfully performed in nearly all colon and rectal cancer patients. The surgical major complication rate was 9 % in colon cancer and 19 % in rectal cancer. The mortality rate was 4 %. CONCLUSION Multivisceral en-bloc resection enables local R0 resection in the majority of cases with primary colorectal cancer. Despite sometimes extensive surgery, this type of procedure is associated with an acceptable morbidity and mortality. Since long-term survival is comparable to that in the T category (T3 or T4), multivisceral en-bloc resection is not only justified but also absolutely required in interventions with curative intention.

Abstract
BACKGROUND/AIMS Accumulation of T lymphocytes in the gut is a hallmark of inflammatory bowel disease probably caused by insufficient T cell apoptosis. Activated peripheral T cells, or "resting" lamina propria T lymphocytes (LPLs), are highly susceptible to apoptosis induction, e.g., using the mitogenic anti-CD2 monoclonal antibody (mAb) pair T11(2+3). It is, however, unknown how CD2-mediated LPL apoptosis is related to proliferation and whether the whole CD2 molecule is required for apoptosis induction. MATERIALS AND METHODS Mapping of anti-CD2 mAb was performed using erythrocyte rosetting assays and cross-blocking enzyme-linked immunosorbent assay (ELISA). Lamina propria mononuclear cells (LPMNCs) or phytohemagglutinin (PHA) blasts were stimulated with a panel of 18 anti-CD2 mAbs followed by apoptosis analysis [Annexin V expression on propidium iodide (PI)-negative cells, 4c6-diamidino-2-phenylindole x 2HCl (DAPI) staining]. Proliferation was measured by [(3)H]-thymidine incorporation. For structural analysis, EL4 cells were used which were transfected with human CD2 (wild type (WT), cytoplasmic-deficient, cytoplasmic CD28). Sorting was performed employing standard techniques RESULTS All three mitogenic anti-CD2 mAb pairs induced apoptosis of LPMNC and PHA blasts. Two out of four submitogenic anti-CD2 mAb, AICD2.M3, and ICRFCD2.3 lead to LPMNC proliferation but no apoptosis. Importantly, apoptosis was also detected in cytoplasmic-deficient CD2 tg or CD2/CD2/CD28 tg EL4 cells. Sorted CD45(high) huCD2 WT EL4 had higher apoptosis rates compared to WT huCD2tg EL4 cells CONCLUSION LPMNC apoptosis induction via CD2 is always associated with proliferation, although proliferation is not necessarily associated with apoptosis. The cytoplasmic tail of CD2 is not required, and CD45 appears to transmit apoptotic signals entering the T cell via CD2.

Abstract
OBJECTIVE Chronic anal fissures are associated with a persistent hypertonia and spasm of the internal anal sphincter. Classic treatment is surgical sphincterotomy to reduce the anal tone and eliminate sphincteric spasm. However, concerns have been raised about the incidence of fecal incontinence after surgery. Therefore, pharmacological means to treat chronic anal fissures have been explored. METHODS We conducted a literature review on MEDLINE database. RESULTS All treatments address the anomaly of a high anal pressure. Several studies have investigated the effect of topical glyceryl trinitrate ointment. Healing rates range from 30% to 86%. Therapy is limited because of a high incidence of moderate to severe headaches in up to 84% of patients. Comparable results are observed after injection of botulinum toxin into the anal sphincter (43-96%). Minor incontinence for flatus and soiling has been reported in up to 12% of patients. Further pharmacological approaches including treatment via calcium channel blockade and treatment with alpha-adrenoceptor antagonists are still at a developmental stage. CONCLUSIONS Topical glyceryl trinitrate ointment and injection of botulinum toxin into the anal sphincter are advocated as the first-line treatment for chronic anal fissure. Lateral sphincterotomy should be offered to patients with relapse and therapeutic failure of prior pharmacological treatment.

Abstract
Endoanal sonography is a well established method for the morphological diagnosis of anal sphincter damage. The best images are obtained using a 7-10 MHz rotating rigid endoprobe. The internal anal sphincter and the external anal sphincter, as well as the other pelvic floor structures, can be clearly visualised with this technique. Endosonography has shown physiological differences in sphincter anatomy and brought new insights into the pathogenesis of anorectal disorders. Apart of anal fistulas, faecal incontinence represents the main indication for the use of this method. In addition, rectal evacuation disorders are an indication for which endosonography allows a first step towards a diagnosis. Anal ultrasound is a technique friendly to both the physician and the patient, and belongs in every coloproctological unit for the assessment of faecal incontinence. Accuracy, specificity and sensitivity for the detection of anal sphincter defects range between 83 and 100% in almost all studies. Additional methods are vaginal endosonography, three dimensional endosonography and perineal sonography.

Abstract
Biofeedback training is a well established method for the treatment of faecal incontinence. Prior to any biofeedback training program, a definitive diagnostic study is essential. Idiopathic faecal incontinence is the main indication for biofeedback training. Additional indications are a menacing faecal incontinence after deep anterior rectal excision with restoration of the rectal reservoir by an ileoanal pouch, anal sphincter reconstruction, rectopexy and rectocele repair. Only four studies provide evidence-based medical criteria. These, as well as numerous uncontrolled studies, show the effectiveness of biofeedback training for the treatment of faecal incontinence. Electrical stimulation of the anal sphincter is only shown to be effective in one controlled study in which it was combined with biofeedback training.

Abstract
Ulcerative colitis can be cured with a reasonable quality of life by the complete excision of the colorectum and construction of an ileoanal pouch. The cure is incomplete since there is a certain incidence of a so called pouchitis. Pouchitis occurs with a frequency of 36 %. A single episode of a pouchitis can be cured easily, but in 8-32 % the concerned patients develop a chronic pouchitis. There are many signs that pouchitis might be a remanifestation of ulcerative colitis. This article gives an overview on the actual state of pathophysiology, pathogenesis and therapy of this disease. Apart of that the surgical aspects of the disease are described.

Abstract
BACKGROUND Endogenous intestinal bacteria and/or specific bacterial pathogens are suspected of being involved in the pathogenesis of inflammatory bowel diseases (IBD). The aim of this study was to investigate IBD tissues for different bacterial population groups harbouring the mucosal surface and/or invading the mucosa. METHODS Tissue sections from surgical resections from the terminal ileum and/or the colon from 24 IBD patients (12 active ulcerative colitis (UC), 12 active Crohn disease (CD)) and 14 non-IBD controls were studied by fluorescent in situ hybridization on a quantifiable basis. RESULTS More bacteria were detected on the mucosal surface of IBD patients than on those of non-IBD controls (P < 0.05). Bacterial invasion of the mucosa was evident in 83.3% of colonic specimens from the UC patients, in 55.6% of the ileal and in 25% of the colonic specimens from the CD patients, but no bacteria were detected in the tissues of the controls. Colonic UC specimens were colonized by a variety of organisms, such as bacteria belonging to the gamma subdivision of Proteobacteria, the Enterobacteriaceae, the Bacteroides/Prevotella cluster, the Clostridium histolyticum/Clostridium lituseburense group, the Clostridium coccoides/Eubacterium rectale group, high G + C Gram-positive bacteria, or sulphate-reducing bacteria, while CD samples harboured mainly bacteria belonging to the former three groups. CONCLUSION Pathogenic events in CD and UC may be associated with different alterations in the mucosal flora of the ileum and colon.

Abstract
BACKGROUND AND AIMS Little is known of the permeability of ileoanal pouches. Hence the aim of the present study was to determine changes in permeability and mucosal function after ileo-pouchanal anastomosis (IPAA) in patients with ulcerative colitis. MATERIALS AND METHODS Biopsies were taken from 43 patients (male:female ratio 28:15; mean age 35.2 (12.5) years) prior to colectomy (ileum prior to pouch), prior to closure of ileostomy (deviation), and after closure of ileostomy (intact pouch) in the case of pouchitis, and from 14 healthy controls. Tissues were mounted in a miniaturised Ussing chamber. Epithelial and subepithelial resistance was determined by transmural impedance analysis. Active Na(+)-glucose cotransport was measured as change in short circuit current after stepwise addition of glucose, and active Cl(-) secretion was measured after stimulation with theophylline and prostaglandin E(2). RESULTS Neither epithelial resistance nor mannitol fluxes were significantly altered compared with intact controls, indicating no barrier defect in pouchitis. Subepithelial resistances of intact pouches and pouchitis were increased compared with deviation (18.2 (1.6) and 24.3 (1.5) v. 13.6 (1.0) Omegaxcm(2)) consistent with an adaptive thickening of the subepithelial layer. In contrast, active Cl(-) secretion of pouchitis tissues was reduced versus intact pouch and controls (1.4 (0.3) v. 4.3 (0.7) and 4.6 (0.7) micromol/h/cm(2)), and Na(+)-glucose cotransport of pouchitis was reduced compared with intact pouch and controls (1.8 (0.5) v. 4.2 (0.8) and 8.8 (1.3) micromol/h/cm(2)). CONCLUSIONS Ileal mucosa in pouchitis and terminal ileum prior to IPAA exhibit impaired secretory and absorptive transport functions whereas the epithelial barrier function remains unchanged. This differs from findings in ulcerative colitis. Thus the hypothesis that pouchitis represents a remanifestation of ulcerative colitis has to be questioned.

Abstract
Colon pouch as neorectum. Technique, indications and results.The possibilities to preserve the intestinal continuity after surgery for rectal cancer have remarkably improved. After straight coloanal anastomosis the problem of a high stool frequency together with urgency was frequently to observe. The introduction of the colonic J-Pouch improved the functional outcome of rectal cancer-surgery very much. In a review of the literature the stool-frequency after one year was 0.5-4 bowel movements per day compared to 0.5-10 per day after straight coloanal anastomosis. Urgency was as well reduced. The parameter of urgency can be best expressed by measuring the urgency volume in balloon-volumetry. Here the volume for J-Pouch was 75 ml compared to 50 ml in straight coloanal anastomosis. At the beginning of colonic J-pouch-surgery evacuation disorders were more frequent observable. Clinical and experimental studies could demonstrate that a big pouch-size caused this problem. Since a pouch-length of 6 cm is used evacuation disorders are very rare. The improved perfusion of the side-to-end anastomosis in pouch-anastomosis reduces the rate of anastomotic leakage's (pouch 1.9 % vs. coloanal anastomosis 15.2 %). In published retrospective studies the oncological outcome is completely comparable to straight coloanal anastomosis. In the case of technical impossibility of J-pouch formation the ileocecal interponant is a possible alternative. This procedure has the same functional outcome.

Abstract
Crohn's disease can neither be cured by surgery nor by medical therapy. Surgical therapy of recurrent Crohn's disease requires special precautions. The recurrence rate is 60% after 15 years. There are no certain data of the risk factors influencing the recurrence rate. The only clear facts are that wide resection out of the resection margins and smoking negatively influence recurrence. Hence, the major principles of therapy is a minimally-resected surgery. This mainly concerns strictures and stenosis. Strictures should be treated by stricturoplasty and stenosis by limited resection with Crohn-free resection margins. Just in case of interenteric and enterocutanous with a concomitant short bowel syndrome, in blind-ending fistulas with an abscess or in enterovesical fistulas, we recommend immediate operation. The therapy of recurrent anorectal Crohn's disease underlies the same rules as primary therapy. If necessary, proctectomy remains the last option. Also, emergency surgery in recurrent Crohn's disease follows the same rules as in elective surgery.

Abstract
A 20-year-old man with a congenital vascular malformation extending from the anal canal into the distal sigmoid had had recurrent perianal blood loss as a neonate. A hemangioma was diagnosed for the first time in 1978. The patient received regular and frequent gastroenterological treatment until admission. Decisive for the indication for surgery was the patient's need for blood infusions and shorter bleeding intervals in June 1998. Surgical therapy consisted of deep anterior rectosigmoid resection with coloanal pouch anastomosis. In a second case of a 27-year-old woman a sigmoid hemangioma was diagnosed in conjunction with emergency sigmoid resectioning. Because of recurrent hemorrhages a coloanal pouch was also established here in a second step. The third case involved a 19-year-old woman with a 12-year history of repeated perianal hemorrhages. After sigmoid discontinuity resection we carried out proctectomy with descendostoma creation due to renewed severe intractable perianal bleeding. The histological examination revealed a rectal hemangioma that had caused the repeated perianal hemorrhages. Surgical reconstruction was then achieved by coloanal pouch anastomosis. In view of the good functional and perioperative results, current surgical therapy should aim at preserving continuity and continence by coloanal pouch anastomosis.

Abstract
Anorectal fistulas don't follow the same rules as idiopathic anorectal fistulas do. Their cause and treatment is completely different. Almost 40% of all patients suffering from Crohn's disease show anorectal manifestations. In 10-15% of the cases the anorectal manifestation is the first sign of Crohn's disease at all. 30% of all fistulas heal at least for a while spontaneously. The diagnostic procedures include nowadays anal endosonography and MRI as most sensitive ones and should be added for every work-up of anorectal Crohn. We differ a conservative from a radical therapy. To our opinion every therapy should be adopted to the individual needs of each patient. The most important principle in anorectal Crohn's disease is laying open of the fistula tract and excision of all the diseased tissue. This should be followed either by a drainage seton or by a definitive plastic closure of the fistula (mucosa-muscle flap). For a mucosa-muscle-flap there is only in otherwise disease-free patients and there only for high transsphincteric fistulas an indication. In our own series we treated of 69 patients 59 with a drainage seton and 10 with a mucosa-muscle flap. Recurrence occurred in 6/59 respectively 2/10 of the treated patients. Anovaginal fistulas should due to the high recurrence rate of surgically closed fistulas (> 50%) only be operated if there are serious symptoms such as recurrent vaginal infection, vaginal flatus and permanent vaginal defecations.

Abstract
Failure of intestinal barrier function and subsequent translocation of bacteria from the gut are believed to play a decisive role in the development of systemic septic complications, for example, following major trauma or major abdominal surgery. This study evaluated: (a) the effect of glutamine on colonic microcirculation and electrophysiological parameters reflecting gut barrier function, (b) the translocation of live bacteria to extraintestinal organs, and (c) disease outcome in two animal models with impaired gut barrier function. Severe acute pancreatitis or colitis was induced in rats randomized for therapy with or without glutamine (0.5 g/kg daily). After 48 h one animal group was prepared for intravital microscopy of colonic capillary blood flow and electrophysiological measurement of gut permeability; another was killed after 96 h for histological and microbiological examination. In animals with pancreatitis, glutamine (Gln) supplementation significantly improved gut permeability, i.e., Gln increased colonic transmucosal resistance from 67+/-7 to 92+/-3 Omega/cm(2) and decreased mannitol flux through the epithelium by 53%. Capillary blood flow in the colonic mucosa was improved by 25%. The prevalence of pancreatic infections was reduced from 86% in animals on standard parenteral nutrition to 33% in animals given the Gln-enriched diet (P<0.05); mortality decreased by 32%. In colitis, Gln had no significant effect on these parameters except for improving colonic capillary blood flow in colon segments not adjacent to the major injury site. Glutamine supplementation improves colonic capillary blood flow, stabilizes gut permeability, and reduces secondary pancreatic infections and mortality in severe rodent pancreatitis, but it is not helpful in colitis. This confirms previous reports that glutamine stabilizes gut barrier function only in certain diseases. Our experimental data strongly suggest that acute pancreatitis (rather than colitis) is one of the diseases with gut barrier dysfunction in which glutamine substitution may be helpful to reduce bacterial translocation and should therefore be tested in a controlled clinical trial.

Abstract
A constant reduction in anal sphincter pressure follows an ileoanal pouch procedure for ulcerative colitis and familiar adenomatous polyposis. We analyzed whether this reduction is more likely due to neurogenic damage or to direct sphincter trauma. Three-dimensional vector volume manometry was performed in 75 patients prior to the ileoanal pouch procedure and 3 months thereafter. Resting pressure was significantly reduced from 83.5 +/- 24.4 to 58.1 +/- 18.0 mmHg and squeezing pressure from 204.7 +/- 63.3 to 173.4 +/- 50.6 mmHg. Moreover, significant vector volume reductions were recorded postoperatively, and the asymmetry index increased significantly (resting: 11.5 +/- 4.1% to 18.4 +/- 7.4%; squeezing: 9.6 +/- 3.1 to 13.0 +/- 6.7%). Functional anal sphincter length at the high-pressure zone remained unchanged. Thus, there was no local damage to proximal or distal anal sphincter segments, which suggests that the postoperative impairment of sphincter function is secondary to neurogenic rather than morphological damage.

Abstract
A 19-year-old woman suffered from recurrent peranal hemorrhage. Over a period of five years she was treated under the suspicion of ulcerative colitis. After a sigmoid resection with a colostomy, proctectomy with an end colostomy followed due to recurrent intractable peranal hemorrhage. Histology of the specimen showed surprisingly a hemangioma of the rectum. Thereafter reconstruction was performed by colopouchanal anastomosis. Afterwards the patient was free of disease and had a good stool-continence. Stool-frequency was twice daily. The second case consisted in a 27-year-old woman who underwent emergency sigmoidectomy due to massive peranal hemorrhage. Here as well diagnosis was a hemangioma of the sigmoid. One year after the first operation the patient had a recurrence of peranal bleeding again due to rectal hemangioma. Since endoscopy and endosonography confirmed a rectal hemangioma a rectal exstirpation with a colopouchanal reconstruction was performed successfully. The reviewed literature shows including the two presented cases a total of 81 cases with rectal hemangiomas. Because of the good results concerning function and morbidity the therapy of choice is rectal exstirpation with colopouchanal reconstruction.

Abstract
Ulcerative colitis can be cured by surgery, and the question of how long conservative therapy should be maintained can be easily answered. It should last as long as there is no indication for surgery. In cases of a colitis-associated cancer, the indication is already the presence of low-grade dysplasia. Rectal cancer can be resected and reconstructed with an ileoanal pouch in UICC I and II down to 3 cm from the dentate line. In cecal tumors lymphadenectomy should be performed under preservation of the ileocolic artery. As for refractory colitis an active course of more than 2-4 episodes per year should not be tolerated and permanently active colitis for no more than 6 months. Surgery is also indicated in emergencies with intractable bleeding after a transfusion of more than 4 units of blood and in toxic courses after therapy-resistance for more than 48 h.

Abstract
Conservative surgery in Crohn's disease causes multiple enteral anastomoses. In 120 patients who underwent resectional surgery for Crohn's disease with a total of 165 anastomoses we analyzed the risk factors (a) number of anastomoses per operation, (b) preoperative cortisone, and (c) the resection margins in relation to the major postoperative complications. With a total of five major complications and no mortality we could not observe an increased risk for a higher morbidity in Crohn's disease surgery with multiple anastomoses.

Abstract
The overall rate of complications after ileal pouch-anal anastomosis is 60%. This rate, however, includes complications such as bowel-obstruction and hernias. Pouch-related complications occur after ileal pouch-anal anastomosis with a frequency of 15-25%. In an analysis of the recent literature the main risk factors are: tension of the ileal pouch-anal anastomosis, anastomotic leakage, lack of protective ileostomy, preoperatively undiagnosed Crohn's disease and the experience of the surgeon. We classified pouch related-complications into (1) surgical complications (leakage, bleeding, pelvic sepsis, fistulas); (2) technical problems (long S-pouch spout, rectal cuff stenosis, etc.); (3) functional problems (anal sphincter insufficiency, night incontinence, hypermotility, evacuation disorders); (4) pouchitis; (5) pouch neoplasias. Pathogenesis, diagnostic features, and medical and surgical therapy are discussed in detail. In our own series of 11 pouch-redo operations we had 6 pouch fistulas (3 related to Crohn's disease, 3 postoperative fistulas), 3 wrongly constructed pouches, 1 chronic pouchitis and 1 long S-pouch spout. In 3 cases the pouch had to be excised completely. Two patients remained with a permanent ileostomy. In 6 patients the pouch could be preserved on long term. Due to the technical complexity, the need to understand pathophysiology and the need for a differentiated diagnostic procedure, this operation should be performed only in specialised centers.

Abstract
Non-traumatic duodenocaval fistulae are rare, but may be the source of massive gastrointestional bleeding with associated fever and sepsis. These fistulae result from penetrating duodenal peptic ulcers or right nephrectomy and subsequent radiation to the upper abdomen. The outcome depends on early diagnosis and surgery before a potentially fatal hemorrhage occurs. The therapy of choice includes closure of the fistula and repair of the duodenum and inferior vena cava. We describe the seventh case with radiogenic duodenal ulcer. Gastrointestinal bleeding occurred 10 years after radical nephrectomy and radiation (60 Gy). The patient survived following partial pancreatoduodenectomy (Whipple).

Abstract
Although not an AIDS-defining malignancy, anal cancer is an evolving problem in HIV-infected patients. Treatment-tolerance to radiotherapy as well as to chemotherapy is supposed to be reduced in patients with HIV-infection. From January 1995 to January 1997, four patients with epidermoid cancer of the anal canal and a long history of HIV-infection but without symptoms of AIDS or repeated severe infections were treated with radiotherapy (n = 1) or radiochemotherapy (n = 3). External beam radiotherapy with 45 Gy to the tumor and pelvic as well as inguinal lymphatic drainage was administered. In tumors larger than T2 N0 lesions an additional boost of 9 Gy was given. Chemotherapy consisted of 5-fluorouracil 1000 mg/m2/24 h, d 1-4 two cycles and Mitomycin C either 1 x 15 mg/m2, d 1 in the first, or 2 x 10 mg/m2, d 1, in the first and fifth week of radiotherapy. Acute reactions were mild to moderate in all patients and all but one treatment could be given as scheduled (1 patient with a delay of 4 days). No excessive acute reactions were seen. Because of the short follow-up, late reactions and local control are not yet evaluable.
