Abstract
BACKGROUND To evaluate the relationship between the ratio of affected lymph nodes (LNR) and clinical and anatomopathological variables in patients with rectal adenocarcinoma submitted or not to neoadjuvant chemoradiotherapy. METHODS The LNR was determined by dividing the number of compromised LNR by the total number of LNR dissected in the surgical specimen. Patients were divided into two groups: with QRT and without QRT. In each group, the relationship between LNR and the following variables was evaluated: degree of cell differentiation, depth of invasion in the rectal wall, angiolymphatic /perineural invasion, degree of tumor regression and occurrence of metastases. The LNR was evaluated in patients with more than 1, LNR (LNR >12) or less (LNR<12) in the surgical specimen with overall survival (OS) and disease-free survival (DFS). The results were expressed as the mean with the respective standard deviation. Qualitative variables were analyzed using Fisher's exact test, while quantitative variables were analyzed using the Kruskal -Wallis and Mann-Whitney tests. The significance level was 5%. RESULTS We evaluated 282 patients with QRT and 114 without QRT, between 1995-2011. In the QRT Group, LNR showed a significant association with mucinous tumors (P=0.007) and degree of tumor regression (P=0.003). In both groups, LNR was associated with poorly differentiated tumors (P=0.001, P=0.02), presence of angiolymphatic invasion (P<0.0001 and P=0.01), perineural (P=0.0007, P=0.02), degree of rectal wall invasion (T3>T2; P<0.0001, P=0.02); Compromised LNR (P<0.0001, P<0.01), metastases (P<0.0001, P<0.01). In patients with QRT, LNR<12 was associated with DFS (5.889; 95%CI1.935-19.687; P=0.018) and LNR>12 with DFS and OS (17.984; 95%CI5.931-54.351; P<0.001 and 10.286; 95%CI 2.654-39.854; P=0.007, respectively). CONCLUSION LNR was associated with histological aspects of poor prognosis, regardless of the use of QRT. In the occurrence of less than 12 evaluated LNR, the LNR was associated only with the DFS. BACKGROUND • Assessment of the lymph nodes during pathological analysis of the surgical specimen is crucial to determine treatment and prognosis. BACKGROUND • Neoadjuvance therapy reduces the number of lymph nodes, being lower than recommended, therefore the lymph node ratio can be an alternative analysis for a better prognosis.

Abstract
BACKGROUND Although the gastrointestinal tract is the most affected by Crohn’s disease (CD), the condition triggers other consequent manifestations, and iron deficiency anemia (IDA) is one of the most common. Intravenous (IV) iron replacement is currently available through several drugs, such as ferric hydroxide sucrose and ferric carboxymaltose (FCM). However, the clinical management of these conditions can be challenging.
AIM To elucidate the drug’s effectiveness, the present study analyzed, through medical records, the clinical and epidemiological data of a cohort of patients with active CD who received IV FCM for the IDA treatment.
METHODS This retrospective observational study included 25 patients with active CD, severe anemia, and refractory to previous conventional treatments. Patients were evaluated two times: During the last treatment with ferric hydroxide sucrose and treatment with FCM.
RESULTS After treatment with FCM, parameters of IDA assessment significantly improved, serum hemoglobin (Hb) levels increased in 93% of patients (P < 0.0001), and in 44%, there was an increase of ≥ 2 g/dL in a single application. In addition, 86% of the patients showed an increase in serum iron (P < 0.0001) and ferritin (P = 0.0008) and 50% in transferrin saturation (P = 0.01). The serum iron levels at baseline showed a negative association with the ileal and colonic CD and use of biologics and a positive association with patients who developed CD later in life after the age of 40 (A3) and with a stenosing (B2) and fistulizing (B3) phenotype. The values of Hb and hematocrit after ferric hydroxide sucrose treatment remained similar to those found before treatment.
CONCLUSION This study demonstrated that FCM is an important therapeutic strategy for treating IDA in CD patients, achieving satisfactory results in refractory cases.

Abstract
Ulcerative colitis (UC) is a chronic intestinal inflammatory disease and familial adenomatous polyposis (FAP) is an autosomal dominant inherited disease. Both diseases, despite being different, may require the same surgical procedure: proctocolectomy with ileal pouch-anal anastomosis (IPAA). The main complication after this procedure is pouch inflammation (pouchitis). This inflammatory complication can affect up to 60 percent of patients who receive IPAA for UC, and a very small percentage of the FAP patients. The purpose of this review was to determine the current molecular mechanisms in its pathogenesis and detail the risk factors involved in pouchitis, its diagnosis, and treatment.

Abstract
BACKGROUND Capnography and carbon dioxide (CO2) insufflation during gastrointestinal endoscopy under sedation are associated with safety and comfort improvements, respectively. Capnography can provide early detection of apnea and hypoxemia, whereas CO2 insufflation causes lower periprocedural discomfort. This is the first study to report the application of volumetric capnography in colonoscopy. OBJECTIVE This study aimed to evaluate the use of volumetric capnography with room air (RA) and CO2 insufflation during routine colonoscopy. METHODS In this prospective cohort study, 101 patients who underwent routine colonoscopy under sedation with volumetric capnography monitoring were included. Insufflation with RA was used to distend the intestinal lumen in group 1 (n=51), while group 2 (n=50) used CO2 insufflation. The primary endpoints were episodes of hypoxia, alveolar hypoventilation, and end-tidal CO2 (EtCO2). The secondary endpoints were tidal volume per minute, consumption of sedation medications, and post-procedure pain using the Gloucester modified pain scale. RESULTS The number of episodes of hypoxia (SpO2<90%) was similar between the groups: four episodes in Group 1 and two episodes in Group 2. The duration of hypoxia was significantly longer in group 2 (P=0.02). Hypoalveolar ventilation (EtCO2) occurred more frequently in Group 2 than in Group 1 (27 vs 18 episodes, P=0.05). Regarding EtCO2, Group 2 showed higher values in cecal evaluation (28.94±4.68 mmHg vs 26.65±6.12 mmHg, P=0.04). Regarding tidal volume per minute, Group 2 had significantly lower values at the cecal interval compared to Group 1 (2027.53±2818.89 vs 970.88±1840.25 L/min, P=0.009). No episodes of hypercapnia (EtCO2 > 60 mmHg) occurred during the study. There was no difference in the consumption of sedation medications between the groups. Immediately after colonoscopy, Group 2 reported significantly less pain than Group 1 (P=0.05). CONCLUSION In our study, volumetric capnography during colonoscopy was feasible and effective for monitoring ventilatory parameters and detecting respiratory complications. CO2 insufflation was safe and associated with less pain immediately after colonoscopy.

Abstract
BACKGROUND The increase in the incidence and prevalence rates of inflammatory bowel disease (IBD) is evident in many newly industrialized countries in Asia, Africa, Eastern Europe, and the American continent. In Brazil, records are still scarce, and further studies on this topic are needed. OBJECTIVE To evaluate the epidemiological profile and clinical characteristics of patients with IBD who were followed up at a reference service in the state of São Paulo. METHODS We retrospectively analyzed the medical records of patients with IBD who were followed up in a Brazilian Referral Center. RESULTS A total of 625 patients was evaluated, 416 with Crohn's disease (CD), 190 with ulcerative colitis (UC), and 19 with indeterminate colitis. The average age of the patients was 31.6 years, with a homogeneous distribution between males and females patients. In patients with CD, the most predominant Montreal classification was A2, L3, and B1, with 44.8% of patients presenting with perianal disease; in UC, it was E2, and S0. The main extraintestinal manifestation was rheumatologic, followed by cutaneous and ophthalmic lesions. The majority of patients (85.4%) used some type of medication, the most frequent being aminosalicylates in patients with UC and biological therapy in patients with CD. Regarding surgeries, in CD, a significant percentage of patients underwent some type of surgical procedure, unlike the UC patients, including fistulotomies and placement of seton, derivative ostomies, enterectomy, ileocecectomy/right colectomy, total or partial colectomy, and strictureplasty. Only 195 (31.2%) patients lived in the city of Campinas, while 443 (70.9%) were from the 7th Regional Health Department (RHD), which corresponds to the macro-region of Campinas. CONCLUSION In this study, most patients came from the 7th RHD of Campinas; the patients were young, with no predominance of either sex; there was a higher frequency of patients with CD (66.6%). Most of them (85.4%) were undergoing pharmacological treatment, and a significant percentage of CD patients had undergone surgery.

Abstract
Inflammatory bowel diseases are chronic illnesses that involve intestinal inflammation and are usually diagnosed as Crohn's disease or ulcerative colitis. As these diseases do not have a cure, the goal of treatment is to induce and maintain remission. Monoclonal antibodies have been recognized as the most advanced therapy to avoid complications and reduce the need for surgical approaches. However, although their effectiveness has been proven by several studies, they can trigger the immune system, induce the occurrence of immunogenicity, which may lead to the loss of response and treatment failure. The purpose of this review is to determine what are the main mechanisms involved in IBD; to assess the recommended treatments; to explore the mechanisms of immunogenicity. We also try to explain the detection and describe the existing advances that make possible the clinical application of these approaches.

Abstract
INTRODUCTION Crohn's disease (CD) is an inflammatory bowel disease (IBD) that affects the gastrointestinal tract and can have a major impact on the patient's quality of life and social/professional activities. Asymptomatic patients, or those with mild symptoms, experience the active disease with subclinical manifestation. Systematic review (SR) was performed to look for evidence for the role of chemokines and adipokines as markers for CD activity. METHODS This SR was conducted by searching published studies in international and regional databases up till July, 2020. CD patients were adults with the disease in activity or remission. All adipokines and chemokines were considered for the analysis and the Rayyan QCRI system was used. RESULTS In total, 20 studies were included. Six addressed chemokines and eight adipokines as potential biomarkers of CD activity. CXCL8 was the most studied chemokine (8 studies) and the results were controversial, with 62.5% showing a significant association with CD activity. CXCL10 was investigated by 4 studies and 50% identified it as a potential biomarker. CCL2, CCL11, CCL26 and CXCL1 were examined by 2 articles each. CXCL8 (P=0.002/P=0.001) and CXCL1 (P<0.001) presented the lowest? P value, which qualifies them as potential markers of disease activity. All the adipokines were tested in peripheral blood but 44.4% were also tested in intestinal mucosa, while the percentage in the chemokines' studies was 76.9% in peripheral blood, 46.1% in intestinal mucosa and 7.6% in urine sample respectively. CONCLUSION The development of disease activity biomarkers for CD is becoming relevant for clinical practice. Chemokines and adipokines have the potential to signalize CD activity, but validation in larger cohorts of patients, preferable multicenter studies are still needed.

Abstract
Abstract
Introduction proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the standard surgical procedure for the treatment of ulcerative colitis (UC) and is associated with the prospect of cure. Experience gained over the years has demonstrated the occurrence of a high number of complications as well as bowel disorders that can compromise quality of life (QoL).
Objective evaluate QoL in patients with IPAA for ulcerative colitis.
Patients and methods the Inflammatory Bowel Disease Questionnaire (IBDQ) was used to assess QoL in patients with IPAA after its validation in Portuguese.
Results thirty-one patients submitted to IPAA by the same group of professionals were evaluated. QoL was classified as regular in all domains evaluated (intestinal and systemic symptoms and emotional and social aspects). There were no differences in relation to gender, type of pouch or postoperative time. However, elderly patients showed a tendency toward lower scores. Having a professional activity was associated with higher scores in systemic symptoms and social aspects (p < 0.05). Patients with ileostomy showed lower values in the domains of systemic symptoms, emotional and social aspects (p <0.05).
Conclusion in all domains assessed, patients with IPAA for UC had QoL classified as regular. Ileostomy and lack of professional activity negatively influenced QoL.

Abstract
Inflammatory bowel diseases (IBDs) are closely linked to nutrition. The latest research indicates that diet and nutrition are significantly involved in the etiopathogenesis of the disease, although their specific role throughout its clinical course still remains unclear. This study reviewed how diet and nutrition are associated with IBD development and management. Even though specific diets have been shown to bring about positive outcomes, there is currently no scientific consensus regarding an appropriate diet that would benefit all IBD patients. We suggest that individualized dietary recommendations are of the greatest importance and that diets should be planned to provide individual IBD patients with specific nutrient requirements while keeping all the clinical aspects of the patients in mind. Further research is clearly necessary to investigate nutritional factors involved in IBD development and, especially, to evaluate the applications of the diets during the course of the disease.

Abstract
Inflammatory bowel diseases (IBD) comprise two major forms: Crohn's disease and ulcerative colitis. The diagnosis of IBD is based on clinical symptoms combined with results found in endoscopic and radiological examinations. In addition, the discovery of biomarkers has significantly improved the diagnosis and management of IBD. Several potential genetic, serological, fecal, microbial, histological and immunological biomarkers have been proposed for IBD, and they have been evaluated for clinical routine and clinical trials. Ileocolonoscopy, especially with biopsy collection, has been considered the standard method to diagnose IBD and to assess clinical activity of the disease, but it is limited to the colon and terminal ileum and is considered invasive. For this reason, non-invasive biomarkers are necessary for this type of chronic inflammatory disease, which affects mostly young individuals, as they are expected to have a long follow-up.

Abstract
Diet is an important factor in both the pathogenesis and in the clinical course of Crohn's disease (CD). However, data on dietary patterns of CD patients are rather limited in the literature. This cross-sectional study included 60 patients with CD, aged 18-60 years. Dietary intake was assessed using a validated food frequency questionnaire to measure food consumption patterns by principal component analysis (PCA). Multiple regression analysis was performed to investigate the association between dietary patterns and clinical and demographic variables. Three dietary patterns were identified: "Traditional + FODMAP" was associated with symptoms, gender, previous surgeries, and duration of the disease. "Fitness style" was positively associated with physical activity and negatively associated with body mass index and smoking. "Snacks and processed foods" was positively associated with duration of the disease and negatively associated with age. According to the weekly food consumption analysis, patients with active disease consumed less coffee and tea. We found significant associations between the three dietary patterns and the variables, but not with the stage of the disease. Prospective studies are necessary to determine the effects of food consumption patterns on the clinical course of CD.

Abstract
OBJECTIVES The aim of this study was to evaluate the quantitative serum level of infliximab (IFX) as well as the detection of anti-infliximab antibodies (ATIs) in patients with Crohn's disease (CD). METHOD Forty patients with CD under treatment at a tertiary center in southeastern Brazil were evaluated. Their use of infliximab was continuous and regular. We analyzed and compared the differences in the IFX and ATI levels between the patients with active CD (CDA) and those with CD in remission (CDR). RESULTS There was no difference in the IFX level between the CDA and CDR groups (p>0.05). Eighty percent of all patients had IFX levels above the therapeutic concentration (6-10 μg/mL). Two (9%) of the 22 patients with active disease and four (22.2%) of the 18 patients in remission had undetectable levels of IFX. Four (66.6%) of the six patients with undetectable levels of IFX had positive ATI levels; three of these patients were in remission, and one had active disease. In addition, the other two patients with undetectable levels of IFX presented ATI levels close to positivity (2.7 and 2.8 AU/ml). None of the patients with therapeutic or supratherapeutic IFX levels had positive ATI levels. CONCLUSIONS The undetectable levels of IFX correlated with the detection of ATIs, which was independent of disease activity. Immunogenicity was not the main factor for the loss of response to IFX in our study, and the majority of patients in both groups (CDA and CDR) had supratherapeutic levels of IFX.

Abstract
An 69-year-old obese woman was submitted to an abdominoperineal resection (APR) with left side end colostomy to treat a synchronic sigmoid and middle rectum cancer. Six months after APR, she develop a PH with a progressive increase of the size. The patient refused the surgical indication. Thirteen years after APR she presenting with abdominal pain, hematemesis, bilious vomiting and non-functioning of the stoma in the last 2 days. She had a distended and painful abdomen without signs of peritoneal irritation and a large incarcerated PH. CT showed a PH with incarcerated gastric herniation. Endoscopy showed a 4 cm ulcerated lesion in the lesser curvature of the stomach whose posteriorly histopathological study revealed that it was an ischemic ulcer. She was submitted a correction of PH using an onlay polypropylene mesh put around of the previous stoma. The patient has an uneventful recovery and was discharged 3 days later.

Abstract
Total retocolectomy with ileal pouch-anal anastomosis (IPAA) is the surgery of choice for patients with ulcerative colitis (UC) that are refractory to clinical treatment. Pouchitis is one of the most common complications after this procedure. Defects in autophagy have been reported in inflammatory bowel diseases. However, there are no studies on the IP. Therefore, we studied markers for autophagy in the IP mucosa of UC and FAP patients comparing them to controls with a normal distal ileum. Sixteen patients with IP in "J" shape, asymptomatic and with endoscopically normal IP were evaluated. The control group consisted of eight patients with normal colonoscopy. There was a significant decrease in the transcriptional levels of ATG5, MAP1LC3A and BAX in the FAP group. There was also a decrease in the protein level of Beclin-1 in the UC and FAP compared to the control group. Although the LC3II levels by immunoblot were higher in the UC group, LC3/p62 co-localization were lower in the immunofluorescence analysis in the UC and FAP compared to the control group. Corroborating these results, there was an increase of p62 by immunoblot in the UC group. These findings indicated a modulation of macroautophagy markers in the IP, which may explain the mucosa inflammation predisposition.

Abstract
Background/Aims The use of anti-tumor necrosis factor (anti-TNF) agents seems to reduce surgical rates and delay surgical procedures in prospective trials and population-based studies in the management of Crohn's disease (CD). This study aimed to identify whether preoperative anti-TNF agents influence the time from diagnosis to surgery. Methods An observational retrospective cohort study was conducted on patients with CD submitted to intestinal resections due to complications or medical therapy failure in a period of 7 years. The patients were allocated into 2 groups according to their previous exposure to anti-TNF agents in the preoperative period. Epidemiological aspects regarding age at diagnosis, smoking, perianal disease, and preoperative conventional therapy were considered. A Kaplan-Meier survival analysis was used to outline possible differences between the groups regarding the time to surgery. Results A total of 123 patients were included (71 and 52 with and without previous exposure to biologics, respectively). The overall time to surgery was 108±6.9 months (maximum, 276 months). The survival estimation revealed no difference in the mean time to intestinal resection between the groups (99.78±10.62 months in the patients without and 114.01±9.07 months in those with previous anti-TNF use) (log-rank P=0.35). There was no significant difference in the time to surgery regarding perianal CD (P=0.49), smoking (P=0.63), preoperative azathioprine (P=0.073) and steroid use (P=0.58). Conclusions The time from diagnosis to surgery was not influenced by the preoperative use of anti-TNF therapy in this cohort of patients.

Abstract
BACKGROUND AND AIMS Ulcerative colitis [UC] is a chronic inflammatory disease of the colon. Colonoscopy remains the gold standard for evaluating disease activity, as clinical symptoms are not sufficiently accurate. The aim of this study is to identify new accurate non-invasive biomarkers based on whole-blood transcriptomics that can predict mucosal lesions and response to treatment in UC patients. METHODS Whole-blood samples were collected for a total of 152 UC patients at endoscopy. Blood RNA from 25 UC individuals and 20 controls was analysed using microarrays. Genes that correlated with endoscopic activity were validated using real-time polymerase chain reaction in an independent group of 111 UC patients, and a prediction model for mucosal lesions was evaluated. Responsiveness to treatment was assessed in a longitudinal cohort of 16 UC patients who started anti-tumour necrosis factor [TNF] therapy and were followed up for 14 weeks. RESULTS Microarray analysis identified 122 genes significantly altered in the blood of endoscopically active UC patients. A significant correlation with the degree of endoscopic activity was observed in several genes, including HP, CD177, GPR84, and S100A12. Using HP as a predictor of endoscopic disease activity, an accuracy of 67.3% was observed, compared with 52.4%, 45.2%, and 30.3% for C-reactive protein, erythrocyte sedimentation rate, and platelet count, respectively. Finally, at 14 weeks of treatment, response to anti-TNF therapy induced alterations in blood HP, CD177, GPR84, and S100A12 transcripts that correlated with changes in endoscopic activity. CONCLUSIONS Transcriptional changes in UC patients are sensitive to endoscopic improvement and appear to be an effective tool to monitor patients over time.

Abstract
BACKGROUND/AIMS Lipopolysaccharide (LPS) is a molecule formed by lipids and polysaccharides and is the major cell wall component of gram-negative bacteria. High LPS levels are known to block CD26 expression by activating Toll-like receptor 4. The aim of this study was to correlate the serum levels of LPS and CD26 in Crohn's disease (CD) patients with serum levels of C-reactive protein (CRP), interleukins, CD activity index, and tumor necrosis factor-α (TNF-α). METHODS Serum samples were collected from 27 individuals (10 with active CD, 10 with inactive CD, and 7 controls) and the levels of LPS, CD26, TNF-α, interleukin-1β (IL-1β), IL-6, IL-17, and CRP were determined by enzyme-linked immunosorbent assay. The levels of LPS and CD26 were then tested for correlation with TNF-α, IL-1β, IL-6, IL-17, and CRP. RESULTS Serum levels of LPS were significantly elevated in the active CD group (P=0.003). Levels of IL-1β (P=0.002), IL-6 (P=0.003), and IL-17 (P<0.001) were lower in the CD groups. Serum TNF-α levels were increased in the active CD group. The CRP levels were elevated in the CD groups when compared to controls (P<0.001). The CD26 levels were lower in the CD groups than in the control group (P<0.001). Among the variables analyzed, there was a correlation between LPS and CRP (r=-0.53, P=0.016) in the CD groups. CONCLUSIONS Individuals with CD exhibited higher serum levels of LPS varying from a 2- to 6-fold increase depending on disease activity, when compared with healthy controls. CD26 levels were lower in the CD groups. Both LPS and CD26 correlated with disease severity and serve as potential CD biomarkers.

Abstract
BACKGROUND The real impact of anti-tumor necrosis alpha (TNF) therapy in postoperative complications after intestinal resections in Crohn's disease (CD) still needs to be determined. AIMS To compare the postoperative complication rates after elective intestinal resections in CD patients, with or without previous exposure to anti-TNF therapy. METHODS This was a retrospective and observational study, with elective intestinal resections for CD (emergency procedures were excluded). Patients were allocated in two groups according to preoperative anti-TNF status. Surgical and medical complications were analyzed and subsequently compared between the groups. RESULTS A total of 123 patients were included (71 with and 52 without preoperative anti-TNF). The groups were considered homogeneous, except for perianal CD, previous azathioprine, and stomas. There was no significant difference between the groups regarding overall surgical complications (32.69% in anti-TNF- vs. 39.44% in anti-TNF+ patients, p = 0.457) or overall medical complications (21.15 vs. 21.13%, respectively, p = 1.000). In univariate analysis, previous steroids, perianal CD, and stomas were considered risk factors for surgical complications, and previous steroids and hypoalbuminemia for medical complications. In multivariate analysis, previous steroids were associated with higher rates of surgical and medical complications, while hypoalbuminemia was associated with higher medical complication rates. CONCLUSIONS There was no influence of the previous use of anti-TNF agents in postoperative surgical and medical complication rates in elective intestinal resections for CD. Previous steroids and hypoalbuminemia were associated with higher complication rates. This was the first case series of the literature describing outcomes in exclusively elective operations.

Abstract
BACKGROUND The approach of locally advanced extra-peritoneal rectal adenocarcinoma implies a treatment with neoadjuvant chemoradiotherapy associated with total mesorectal excision surgery. However, the tumors respond variably to this neoadjuvant therapy, and the mechanisms for response are not completely understood. OBJECTIVE Evaluate the variables related to the complete tumor response and the outcomes of patients who underwent surgery, comparing those with partial tumor regression and those with total remission of rectal lesion, at the pathological examination. METHODS Retrospective analysis of medical records of 212 patients operated between 2000 and 2010, in which 182 (85.9%) obtained partial remission at neoadjuvant therapy (Group 1) and 30 (14.1%), total remission (Group 2). RESULTS No difference was found between the groups in relation to gender, ethnicity, age, tumor distance from the anal verge, occurrence of metastases and synchronous lesions on preoperative staging, dose of radiotherapy and performed surgery. In Group 2, was verified high rate of complete remission when the time to surgery after neoadjuvant therapy was equal or less than 8 weeks (P=0.027), and a tendency of lower levels of pretreatment carcinoembryonic antigen (P=0.067). In pathological analysis, the Group 1 presented in relation to Group 2, more affected lymph nodes (average 1.9 and 0.5 respectively; P=0.003), more angiolymphatic (19.2% and 3.3%; P=0.032) and perineural involvement (15.4% and 0%; P=0.017) and greater number of lymph nodes examined (16.3 and 13.6; P=0.023). In the late follow-up, Group 1 also had lower overall survival than Group 2 (94.1 months and 136.4 months respectively; P=0.02) and disease-free survival (85.5 months and 134.6 months; P=0.004). There was no statistical difference between Group 2 and Group 1 in local recurrence (15% and 3.4%, respectively) and distant metastasis (28% and 13.8%, respectively). CONCLUSION In this study, the only factor associated with complete remission of rectal adenocarcinoma was the time between neoadjuvant therapy and surgery. This group of patients had less affected lymph nodes, less angiolymphatic and perineural involvement, a longer overall and disease-free survival, but no significant statistical difference was observed in local recurrence and distant metastasis. Although the complete pathologic remission was associated with better prognosis, this not implied in the cure of the disease for all patients.

Abstract
Mucinous adenocarcinoma associated with suppurative hidradenitis is extremely rare. Magnetic resonance imaging findings help in the diagnosis of mucinous adenocarcinoma. The surgery is highly complex, and even in a tertiary hospital, complications may occur.
Introduction Chronic suppurative hidradenitis (CSH) is a benign condition that can affect the perineal region and often leads to the formation of abscesses and fistulas. It is rare for CSH to undergo malignant degeneration into mucinous adenocarcinoma. Presentation of case We report a case of a 55-year-old male patient with perineal CSH who suffered worsening long-term pain despite multiple surgical procedures to alleviate his symptoms. Pelvic magnetic resonance imaging (MRI) showed multiloculated cystic lesion on the left side wall of the distal rectum with gluteal extension. Pathological examination revealed mucinous adenocarcinoma. The patient underwent an abdominoperineal resection (APR) of the rectum with cutaneous muscle flap reconstruction. Although histopathological sections showed clear margins, the tumor recurred 6 months following surgery. Discussion Perineal mucinous adenocarcinoma arising in a patient with CSH is an extremely rare condition. This diagnosis is often difficult, due to the paucity of signs of malignant degeneration as well as the rarity of the disease itself. Surgical resection of the lesions is a well-established approach. In this case, diagnosing the tumor at such a late stage likely compromised his outcome. Conclusion Malignant degeneration to mucinous adenocarcinoma must be suspected in patients with a history of long-term CSH. In such cases, local biopsies and a radiological examination, such as MRI can help in the diagnosis.

Abstract
BACKGROUND Crohn's disease (CD) is associated with complex pathogenic pathways involving defects in apoptosis mechanisms. Recently, mesenteric adipose tissue (MAT) has been associated with CD ethiopathology, since adipose thickening is detected close to the affected intestinal area. However, the potential role of altered apoptosis in MAT of CD has not been addressed. AIMS To evaluate apoptosis in the intestinal mucosa and MAT of patients with CD. METHODS Samples of intestinal mucosa and MAT from patients with ileocecal CD and from non-inflammatory bowel diseases patients (controls) were studied. Apoptosis was assessed by TUNEL assay and correlated with the adipocytes histological morphometric analysis. The transcriptional and protein analysis of selected genes and proteins related to apoptosis were determined. RESULTS TUNEL assay showed fewer apoptotic cells in CD, when compared to the control groups, both in the intestinal mucosa and in MAT. In addition, the number of apoptotic cells (TUNEL) correlated significantly with the area and perimeter of the adipose cells in MAT. Transcriptomic and proteomic analysis reveal a significantly lower transcript and protein levels of Bax in the intestinal mucosa of CD, compared to the controls; low protein levels of Bax were found localized in the lamina propria and not in the epithelium of this tissue. Furthermore, higher level of Bcl-2 and low level of Caspase 3 were seen in the MAT of CD patients. CONCLUSION The defective apoptosis in MAT may explain the singular morphological characteristics of this tissue in CD, which may be implicated in the pathophysiology of the disease.

Abstract
PURPOSE To evaluate the effects of peritoneal lavage with bupivacaine on survival and initial resistance of anastomosis on distal colon, performed under peritonitis or not. METHODS Forty rats, weighing from 300 to 350 g (321.29 ± 11.3 1g), were randomly divided in four groups and underwent laparotomy and anastomosis on the distal colon six hours after induction of peritonitis by intraperitoneal injection of autologous fecal material or not. Group 1: No peritonitis and lavage with 3 ml NS; Group 2: No peritonitis and lavage with 8 mg.kg-1 (± 0.5 mL) of 0.5% bupivacaine added to 2.5 mL of NS; Group 3: Peritonitis and lavage with 3 ml NS; Group 4: Peritonitis and lavage with 8 mg.kg-1 (± 0.5 mL) of 0.5% bupivacaine added to 2.5 mL of NS. Necropsies were performed on the animals that died and the time of death was recorded. Surviving animals were submitted to euthanasia on the fifth post-operative day and Total Energy of Rupture biomechanical test (TER) was applied. RESULTS Group 4 showed survival increase compared to Group 3, without statistical significance. Group 3 presented the smallest average TER, with statistical significance. CONCLUSION Peritonitis increased mortality and influenced negatively the resistance of colic anastomosis in rats. Peritoneal lavage with bupivacaine increased anastomotic resistance.

Abstract
CONTEXT Desmoid tumors constitute one of the most important extraintestinal manifestations of familial adenomatous polyposis. The development of desmoids is responsible for increasing morbidity and mortality rates in cases of familial adenomatous polyposis. OBJECTIVES To evaluate the occurrence of desmoid tumors in familial adenomatous polyposis cases following prophylactic colectomy and to present patient outcome. METHODS Between 1984 and 2008, 68 patients underwent colectomy for familial adenomatous polyposis at the School of Medical Sciences Teaching Hospital, University of Campinas, SP, Brazil. Desmoid tumors were found in nine (13.2%) of these patients, who were studied retrospectively by consulting their medical charts with respect to clinical and surgical data. RESULTS Of nine patients, seven (77.8%) were submitted to laparotomy for tumor resection. Median age at the time of surgery was 33.9 years (range 22-51 years). Desmoid tumors were found in the abdominal wall in 3/9 cases (33.3%) and in an intra-abdominal site in the remaining six cases (66.7%). Median time elapsed between ileal pouch-anal anastomosis and diagnosis of desmoid tumor was 37.5 months (range 14-60 months), while the median time between colectomy with ileorectal anastomosis and diagnosis was 63.7 months (range 25-116 months). In 6/9 (66.7%) patients with desmoid tumors, the disease was either under control or there was no evidence of tumor recurrence at a follow-up visit made a mean of 63.1 months later (range 12-240 months). CONCLUSIONS Desmoid tumors were found in 13.2% of cases of familial adenomatous polyposis following colectomy; therefore, familial adenomatous polyposis patients should be followed-up and surveillance should include abdominal examination to detect signs and symptoms. Treatment options include surgery and clinical management with antiestrogens, antiinflammatory drugs or chemotherapy.

Abstract
PURPOSE To analyze the effects of hyperbaric oxygen therapy (HBO) on the mechanical resistance of anastomosis performed in rats' distal colon presenting peritonitis induced by ligature and cecal punction using the Total Energy Rupture biomechanical test (ETR). METHODS It was used 45 rats divided into three groups of 15 animals each. In Control Group (CG), it was performed anastomosis in distal colon without peritonitis. In Peritonitis Group (PG), it was performed anastomosis six hours after the induction of peritonitis by ligature and cecal punction. In Hyperbaric Chamber Group (HCG), it was performed six hours after the induction of peritonitis by ligature and cecal punction. The animals on CG and PG were kept at place air while the animals on HCG were placed on an experimental hyperbaric chamber in order to inhale oxygen at 100%, two absolute atmospheres, for 120 minutes, for four consecutive days. Euthanasia took place on the fifth day of the experiment. All the animals underwent to Total Energy Rupture Biomechanical Resistance test (ETR). Total Energy Rupture was defined as the necessary internal energy stored up to promote the colon rupture after an external traction force imposition. RESULTS The Peritonitis Group presents smaller average ETR than Control Group. There was no statistical difference between Peritonitis Group and Hyberbaric Chamber Group. CONCLUSION Hyperbaric oxygen therapy did not alter the mechanical resistance of anastomosis performed in distal colon of rats under the presence of peritonitis induced by ligature and cecal puncture.

Abstract
CONTEXT Intestinal constipation--a common symptom among the general population--is more frequent in women. It may be secondary to an improper diet or organic or functional disturbances, such as dyskinesia of the pelvic floor. This is basically characterized by the absence of relaxation or paradoxical contraction of the pelvic floor and anal sphincter during evacuation. OBJECTIVE To analyze, by manometric data, the anal pressure variation at rest, during evacuation effort by using the Valsalva maneuver and forced post-expiratory apnea in subjects with secondary constipation. METHODS Twenty-one patients (19 females--90.4%) with a mean age of 47.5 years old (23-72) were studied. The diagnosis was performed using anorectal manometry, with a catheter containing eight channels disposed at the axial axis, measuring the proximal (1) and distal (2) portions of the anal orifice. The elevation of the pressure values in relation to the resting with the evacuation effort was present in all patients. The Agachan score was used for clinical evaluation of constipation. The variables studied were: mean anal pressure of the anal orifice for 20 seconds at rest, the effort of evacuation using Valsalva maneuver and the effort of evacuation during apnea after forced expiration, as well as the area under the curve of the manometric tracing at moments Valsalva and apnea. RESULTS The analysis of the mean values of the anal pressure variation at rest evidenced difference between proximal and distal channels (P = 0.007), independent of the moment and tendency to differ during moments Valsalva and apnea (P = 0.06). The mean of values of the area under the manometric tracing curve showed differences between moments Valsalva and apnea (P = 0.0008), either at the proximal portion or at the distal portion of the anal orifice. CONCLUSION The effort of evacuation associated with postexpiratory apnea, when compared with the effort associated with the Valsalva maneuver, provides lower elevation of anal pressure at rest by the parameter area under the curve.

Abstract
PURPOSE: To analyze influence of omentoplasty on anastomosis in descending colon of rats. Rats were submitted to the hypovolemic shock of the hemorrhagic type by the Biomechanical Test of Pressure of Rupture by Liquid Distension (BTPRLD). In addition, establish a type of acute anemia in rats that are provided to the study. METHODS: Comparative study between two groups of animals with ten rats in each one, all submitted to hemorrhagic shock for 30% volemic removal by the carotid artery. An anastomosis was performed in left colon. An anastomosis was performed in the left colon. Group 1 took place anastomosis with Polyvinyl Chloride (P.V.C) film to prevent the adhesions formation on sature line. Group 2 placed the great omentum around the anastomosis. Euthanasia occurred on the fifth day, when the anastomoses were submitted to the biomechanical test of pressure of rupture by liquid distension (BTPRLD). RESULTS: High rupture pressure was gained with omentoplasty group in relation to the group in which anastomosis was protected from adhesions formation. A statistical significance was noted. CONCLUSION: Protection by great omentum has increased the anastomosis resistance of the shocked animals. Also, the proposed hemorrhagic shock type has proven to be useful for this study.

Abstract
BACKGROUND Total rectocolectomy and ileal pouch-anal anastomosis is the choice surgical procedure for patients with ulcerative colitis. In cases of Crohn's disease post-operative diagnosis, it can be followed by pouch failure. AIM To evaluate ileal pouch-anal anastomosis long-term outcome in patients with Crohn's disease. METHODS Between February 1983 and March 2007, 151 patients were submitted to ileal pouch-anal anastomosis by Campinas State University Colorectal Unit, Campinas, SP, Brazil, 76 had pre-operative ulcerative colitis diagnosis and 11 had post-operative Crohn's disease diagnosis. Crohn's disease diagnosis was made by histopathological biopsies in nine cases, being one in surgical specimen, two cases in rectal stump, small bowel in two cases, ileal pouch in three and in perianal abscess in one of them. The median age was 30.6 years and eight (72.7%) were female. RESULTS All patients had previous ulcerative colitis diagnosis and in five cases emergency colectomy was done by toxic megacolon. The mean time until of Crohn's disease diagnosis was 30.6 (6-80) months after ileal pouch-anal anastomosis. Ileostomy closure was possible in 10 cases except in one that had ileal pouch fistula, perianal disease and small bowel involvement. In the long-term follow-up, three patients had perineal fistulas and one had also a pouch-vaginal fistula. All of them were submitted to a new ileostomy and one had the pouch excised. Another patient presented pouch-vaginal fistula which was successfully treated by mucosal flap. Three patients had small bowel involvement and three others, pouch involvement. All improved with medical treatment. Presently, the mean follow-up is 76.5 months and all patients are in clinical remission, and four have fecal diversion. The remaining patients have good functional results with 6-10 bowel movements/day. CONCLUSION Crohn's disease diagnosis after ileal pouch-anal anastomosis for ulcerative colitis may be usual and later complications such fistulas and stenosis are common. However, when left in situ ileal pouch is associated with good function.

Abstract
PURPOSE: To evaluate the effect of hemorrhagic shock in colonic anastomoses in rats, with a rupture by liquid distension resistance test. METHODS: Wistar lineage rats, averaging 90 days old and weighing from 310 to 380 grams were divided into two groups. In the first group (G1), 10 animals were submitted to colonic anastomoses in normovolemic terms and the second group (G2), of 10 animals, was submitted to colonic anastomoses in hypovolemic conditions. The shock was caused by half milliliter of blood withdrawn, every two minutes, until the value of average 50mmHg arterial pressure or a total volume corresponding 30% withdrawal of volemia was reached. Serum lactate dosages were carried out at the beginning and end of the procedure. The average serum lactate values at the end of the surgery were 1.91 mmol/l in G1 group and 3.69 mmol/l in G2 group (p<0.05). On the fifth postoperative day, the animals were euthanized. The anastomoses were evaluated with a rupture by liquid distension resistance test. RESULTS: In G1, the average value of colonic rupture was 160.7 mmHg whereas in G2 it was 152.1mmHg (p>0.05). CONCLUSION: Hemorrhagic shock, under the established conditions of this study, had no influence on colonic anastomoses in rats evaluated with the rupture by liquid distention resistance test.

Abstract
In developing countries, low budgets make the issue of integrating genetics into clinical practice a challenge, a situation in which the use of family history (FH) becomes important for patient care, as it is a low cost strategy and a risk assessment tool. The purpose of this study was to review medical records of patients with colorectal cancer (CRC) seen in a public University Hospital and evaluate how often FH of cancer is registered. Initially we searched a database for patients who were seen in our hospital between 2002 and 2004 with the diagnosis of CRC. We found 415 patients, 104 of whom were excluded. A total of 311 charts were reviewed and classified into 3 groups. Group A: no FH documented; group B: FH was documented, but FH of cancer was not collected; and group C: FH of cancer was documented. We also investigated what type of information was recorded, in order to verify if important elements were assessed. Ninety-eight charts (31.5%) were classified in group A, 20 (6.5%) in group B, and 193 (62%) in group C. In addition, we observed that important information regarding affected relatives was not collected in most of the charts. In conclusion, we found that although FH of cancer was recorded in 62% of charts of patients with CRC, information that could be relevant for risk assessment and management of at-risk families was missing. Our findings expose an important problem in health education that could reflect negatively in the quality of medical assistance to individuals at risk for familial cancer.

Abstract
BACKGROUND Strictureplasty is an alternative surgical procedure for Crohn's disease, particulary in patients with previous resections or many intestinal stenosis. AIM To analyze surgical complications and clinical follow-up in patients submitted to strictureplasty secondary to Crohn's disease. METHODS Twenty-eight patients (57.1% male, mean age 33.3 years, range 16-54 years) with Crohn's disease and intestinal stenosis (small bowel, ileocecal region and ileocolic anastomosis) were submitted to strictureplasty, at one institution, between September 1991 and May 2004. Thirteen patients had previous intestinal resections. The mean follow-up was 58.1 months. A total of 116 strictureplasties were done (94 Heineke-Mikulicz--81%, 15 Finney--13%, seven side-to-side ileocolic strictureplasty--6%). Three patients were submitted to strictureplasty at two different surgical procedures and two in three procedures. RESULTS Regarding to strictureplasty, postoperative complication rate was 25% and mortality was 3.6%. Early local complication rate was 57.1%, with three suture leaks (10.7%) and late complication was present in two patients, both with incisional hernial and enterocutaneous fistulas (28.6%). Patients remained hospitalized during a medium time of 12.4 days. Clinical and surgical recurrence rates were 63% and 41%, respectively. Among the patients submitted to another surgery, two patients had two more operations and one had three. Recurrence rate at strictureplasty site was observed in 3.5%, being Finney technique the commonest one. Presently, 19 patients had been asymptomatic with the majority of them under medical therapy. CONCLUSION Strictureplasties have low complication rates, in spite of having been done at compromised site, with long term pain relief. Considering the clinical course of Crohn's disease, with many patients being submitted to intestinal resections, strictureplasties should be considered as an effective surgical treatment to spare long intestinal resections.

Abstract
RACIONAL: As manifestações extracólicas, como os pólipos gastroduodenais e o tumor do duodeno, são fatores que influenciam a morbimortalidade dos doentes com polipose adenomatosa familiar no seguimento pós-retocolectomia total. OBJETIVO: Investigar a freqüência destas alterações em doentes com polipose adenomatosa familiar e verificar a eficácia do rastreamento endoscópico. MÉTODO:No período de 1984 a 2005, 62 doentes com polipose adenomatosa familiar pós-retocolectomia foram estudados retrospectivamente pelo Grupo de Coloproctologia da Faculdade de Ciências Médicas da Universidade Estadual de Campinas, SP. O tempo de seguimento médio pós-operatório foi de 81,9 meses, sendo que em 53 (85,5%) foi possível analisar a ocorrência de pólipos gastroduodenais. RESULTADOS: Dos 53 doentes em seguimento, 27 (50,9%) apresentavam pólipos gastroduodenais. Em 8 (15,4%) os pólipos adenomatosos eram gástricos, 14 (27%) pólipos duodenais e 5 (9,6%) pólipos gástricos e duodenais. Dois doentes (3,8%) desenvolveram adenoma duodenal com displasia de alto grau. E outro (1,9%), adenocarcinoma em papila duodenal. CONCLUSÃO: O rastreamento endoscópico, desta forma, é de grande importância e o objetivo é detectar, o mais precocemente possível, os casos de adenocarcinoma duodenal e pólipos gastroduodenais com displasia de alto grau.

Abstract
PURPOSE: To analyze and to evaluate the effect of the hyperbaric hyperoxygenation in the mechanical resistance of ischemic colon of rats. METHODS: Eighty rats, distributed in four groups of 20 animals in each one, were used. In group 1 (G1), the control group, ischemia was not caused. Group 2 was submitted to the lesser degree of ischemia. Group 3 was submitted to the intermediate degree of ischemia. In group 4, a bigger degree of intestinal ischemia was provoked. Each group was divided in two sub-groups of ten animals each: with hyperbaric chamber (CC) and without hyperbaric chamber (SC). The animals of the four CC subgroups were placed in an experimental hyperbaric chamber in order to inhale oxygen at 100%, at two Absolute Atmospheres, for 120 minutes, for a four-day consecutive period. The animals of the four SC subgroups were kept in environment air during the five days of the experiment. All animals have been submitted to the mechanical study of the intestinal loop by the pressure test of the rupture by liquid distension. The euthanasia occurred in the fifth post-operative day. RESULTS: Considering the ischemia factor, the four groups were different among them (p=0.0001). There was no statistical difference between subgroups CC and SC (p=0.3461). CONCLUSION: The hyperbaric oxygen-therapy did not present improvement on the induced ischemia in rats upright colic loop.

Abstract
OBJETIVO: Avaliar o efeito das aderências dirigidas sobre a resistência mecânica de anastomoses realizadas em cólon isquêmico através da aplicação dos testes Resistência à Pressão de Explosão e Resistência à Força de Tração. MÉTODOS: Quarenta ratos foram distribuídos igualmente em dois grupos. O Grupo 1 era constituído de vinte animais em que as anastomoses cólicas isquêmicas foram recobertas por uma película de polivinilcloreto (P.V.C.) para impedir a formação de aderências sobre as linhas de sutura e o Grupo 2 era constituído por 20 animais em que as anastomoses cólicas isquêmicas foram recobertas pela gordura epididimal, de forma a constituir uma aderência dirigida sobre a linha de sutura, sendo ainda recobertas por uma película de P.V.C. para impedir a formação de outras aderências. RESULTADOS: A média da Pressão de Ruptura à Distensão por Líquidos da anastomose foi de 10 mmHg no grupo sem aderência e de 55,2 mmHg no grupo com aderência (p < 0,05). A média da Força de Ruptura à Tração das anastomoses foi de 142,5 gf no grupo sem aderências e de 262 gf no grupo com aderência (p < 0,05). CONCLUSÃO: As aderências mostraram ser benéficas, elevando a resistência intrínseca das anastomoses tanto na Resistência à Distensão por Líquido quanto na Resistência à Força de Tração.

Abstract
BACKGROUND: The rectoanal inhibitory reflex has an important rule in the fecal continence mechanism. Alterations in this reflex can be associated with compromised anal sphincteric function. AIM: To identify possible correlation between rectoanal inhibitory reflex parameters and intestinal constipation due to obstructive evacuation. PATIENTS: Sixty nine patients with intestinal constipation had been submitted to anorectal manometry. It was selected 29 patients (27 female, mean age of 42.3 (19-73) years) having intestinal constipation owing to obstructive evacuation. Thirteen individuals without anorectal functional complaints (eight female, mean age 52.5 (28-73) years) formed the control group. RESULTS: The mean value of resting anal pressure before rectoanal inhibitory reflex in the proximal and distal anal canals were 61.8 mm Hg and 81.7 mm Hg respectively, for the constipated patients, and 46.0 mm Hg and 64.5 mm Hg, respectively, for asymptomatic individuals. The mean pressure at the point of maximal relaxation in constipated patients was 29.0 mm Hg in the proximal anal canal, and 52.1 mm Hg in the distal anal canal, whilst in the asymptomatic group they were 17.8 mm Hg and 36.3 mm Hg, respectively. The mean percentage difference between the mean resting anal pressure and the mean point of maximal relaxation pressure in the proximal anal canal (amplitude of relaxation) was 54.1% in constipated patients and 54.3% in asymptomatic individuals. In the distal anal canal it was, respectively, 35.6% in constipated patients, and 38.5% in the control group. The average recovery velocity of relaxation in the proximal anal canal was 4.06 mm/second in constipated patients and 2.98 mm/second in asymptomatic individuals, giving a significant difference between the two groups, as well as in the distal anal canal (3.9 mm/second and 2.98 mm/second, respectively) CONCLUSION: The greater recovery velocity of the resting anal pressure in the proximal anal canal in constipated patients than in controls may be associated with obstructive evacuation.

Abstract
OBJETIVO: Avaliar a ação de aderências sobre anastomose em cólon descendente de ratos por meio de análises biomecânicas. MÉTODOS: Noventa ratos foram distribuídos igualmente em três grupos. O Grupo 1 submeteu-se ao teste Pressão de Ruptura à Distensão por Líquido, enquanto que os Grupos 2 e 3, aos testes Força de Ruptura à Tração e Tensão Resultante Final de Ruptura à Tração, respectivamente. Cada grupo foi subdividido em 3 subgrupos contendo 10 animais. Um subgrupo foi analisado com as aderências deixadas intactas ao redor da anastomose; em outro, as aderências foram removidas, enquanto no último não se permitiu a fixação de aderências nas anastomoses por meio de proteção com película de polivinilcloreto (P.V.C.). RESULTADOS: A eutanásia ocorreu no quinto dia pós-operatório e os subgrupos com as aderências intactas nas anastomoses apresentaram maior resistência à ruptura em relação aos subgrupos com aderências removidas. Os subgrupos com ausência de aderências nas anastomoses apresentaram menor resistência à ruptura (Grupo1-p=0,0001, Grupo 2-p=0,0003 e Grupo3-p=0,0001). CONCLUSÃO: Aderências constituem influências benéficas sobre a anastomose, aumentando a sua resistência mecânica na fase inicial do reparo tecidual.

Abstract
OBJETIVO: Avaliar a eficácia da preservação da arcada vascular do cólon direito (AVCD) na manutenção da perfusão sangüínea do reservatório após manobras de alongamento do mesentério ileal. MÉTODOS: O estudo incluiu 46 pacientes (janeiro/1990 a julho/2000, para o tratamento de retocolite ulcerativa (RCU) e polipose adenomatosa familiar (PAF), que foram divididos em dois grupos: grupo com preservação da arcada (CPA), 27 pacientes, média de idade - 34,0 (19-53) anos, 15 (55,6%) eram do sexo feminino e 24 (88,9%) eram brancos; e grupo sem preservação da arcada (SPA), 19 pacientes, média de idade 41,5 (13 - 62) anos, oito (42,1%) eram do sexo feminino e 18 (94,8%) eram brancos. Trinta pacientes (65,2%) apresentavam RCU e 16 (34,7%) PAF. Foram comparadas a ocorrência de complicações atribuídas à má perfusão sangüínea ou tensão na anastomose ileoanal, assim como as indicações de reoperações. RESULTADOS: No grupo CPA, em quatro pacientes (18,5%), as complicações estavam relacionadas ao comprometimento da viabilidade intestinal ou à tensão ao nível da anastomose. No grupo SPA, estas complicações ocorreram em sete pacientes (36,9%). Foram reoperados três pacientes (11,1%) do grupo CPA, por causas relacionadas ou à má perfusão sangüínea ou à tensão excessiva no nível da anastomose e no grupo SPA cinco (26,3%), pela mesma causa. CONCLUSÕES: Apesar das limitações metodológicas, observou-se tendência para menor ocorrência de complicações isquêmicas no grupo com preservação da AVCD. Quando o abaixamento do reservatório ileal tem que ser ao nível da linha pectínea, torna-se importante a perfusão sangüínea via AVCD como auxiliar na preservação de sua viabilidade.

Abstract
O reservatório ileal pélvico tem sido a melhor opção cirúrgica para a retocolite ulcerativa (RCU) e polipose adenomatosa familiar (PAF). Desde 1983 esta técnica vem sendo empregada, e o objetivo deste trabalho é apresentar revisão desta casuística, analisando seus resultados e seus pontos controversos. Setenta e três pacientes, com média de idade de 34,6 (13-63) anos e com predomínio do sexo feminino (42 pacientes, 56,7%) se submeteram ao procedimento para tratamento de RCU (46 pacientes - 63,0%) e PAF(27 - 37,0%). Foram utilizadas as seguintes variantes técnicas: em S, de grande tamanho e ramo eferente longo (oito); em S pequeno e ramo eferente reduzido (22); em "dupla câmara" (20); em J (23). Todos os procedimentos foram seguidos da construção de ileostomia de proteção. De 1993 em diante, todos os pacientes tiveram a arcada do colo direito preservada. Setenta pacientes têm pelo menos um ano de pós-operatório e 61 têm dois anos ou mais com média de 7,01 (1-16) anos. Foram consideradas complicações precoces aquelas que ocorreram até o 30º dia de pós- operatório e tardias, após esse tempo. Resultados funcionais foram analisados após um ano do fechamento da ileostomia. Ocorreram 35 complicações precoces em 22 pacientes e 39 complicações tardias em 35 pacientes. Vinte e cinco pacientes não apresentaram complicações. As principais complicações foram: obstrução intestinal (19,1 %), fistulizações cutâneas, com vagina ou trato urinário (10,9%), isquemia de reservatório (parcial ou total), (9,5%), e ileíte do reservatório (pouchitis) (6,8%). Nove pacientes (12,3%) têm ileostomia funcionante, sendo que sete pacientes têm ainda o reservatório mantido no lugar e dois tiveram-no ressecado. A mortalidade diretamente relacionada ao procedimento foi em dois pacientes, mas outros quatro pacientes evoluíram tardiamente ao óbito, por causas como desnutrição crônica e tumor de cerebelo. Em conclusão, apesar da morbidade e da existência ainda de questões controversas, as perspectivas tardias têm sido animadoras e têm estimulado a indicação deste tipo de procedimento.
