Abstract
PURPOSE To explore whether previous participation in clinical studies increases adherence to management guidelines in acute uncomplicated diverticulitis (AUD). METHODS This retrospective cohort study was designed to give a SNAPSHOT of the management of AUD at six hospitals, three of which had participated in the AVOD trial comparing antibiotic versus non-antibiotic treatment of AUD. Patients with AUD were included from March 2019 through June 2020 and followed for 90 days. The primary outcome was treatment of AUD categorised by antibiotic treatment and inpatient or outpatient management compared between AVOD and non-AVOD hospitals. Descriptive statistics were compiled, and differences between hospitals were assessed with Pearson's chi-squared test. RESULTS The cohort included 449 patients with AUD of which 63% were women and the median age was 63 (IQR: 52-73) years. Patient characteristics were comparable across the hospitals. Antibiotics were administered to 84 (19%) patients and 113 (25%) patients were managed as inpatients. Management varied significantly between AVOD and non-AVOD hospitals. The mean proportion of patients treated with antibiotics was 7% at AVOD hospitals compared to 38% at non-AVOD hospitals (p < 0.001). The mean proportion of in-hospital management was 18% at AVOD hospitals versus 38% at non-AVOD hospitals (p < 0.001). CONCLUSION Most patients with AUD were managed according to current guidelines. However, the management varies between hospitals and previous participation in clinical studies may increase knowledge of and adherence to guidelines.

The first study appraising colonic diverticulosis and Helicobacter pylori diagnosed by histopathology. REVISTA DA ASSOCIACAO MEDICA BRASILEIRA (1992) 2024; 70:e20240400. [PMID: 39045971 PMCID: PMC11288258 DOI: 10.1590/1806-9282.20240400] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/17/2024] [Accepted: 03/18/2024] [Indexed: 07/25/2024]
Abstract
OBJECTIVE Colonic diverticulosis might be caused by low-fiber dietary habits, gastrointestinal motility disorders, and colonic wall resistance changes, which might also affect the upper gastrointestinal system mucosa. Therefore, the present study aims to answer whether the gastric histopathological findings of the cases with diverge from those without. METHODS This retrospective cross-sectional study included 184 cases who underwent both upper and lower gastrointestinal endoscopy procedures between January 2020 and December 2022. Notably, 84 cases were colonic diverticulosis, while the rest of the study group was control. Their demographic, laboratory, and histopathological findings were compared meticulously. RESULTS The median ages for the colonic diverticulosis and control were 67.07±8.14 and 66.29±15.83 years, respectively, and no statistical difference concerning the age and gender distribution between them was recognized. The median levels of white blood cells, neutrophils, glucose, creatinine, and aspartate aminotransferase in colonic diverticulosis were significantly increased compared to control. As for pathological comparison, colonic diverticulosis had a higher prevalence of Helicobacter pylori (45.2 vs. 38%), while atrophy and intestinal metaplasia prevalence were nearly the same in the groups, without significance regarding Helicobacter pylori. CONCLUSION Consequently, colonic diverticulosis should not be overlooked, particularly when the abovementioned laboratory parameters are augmented in a dyspeptic patient. A correlation might be raised between Helicobacter pylori and colonic diverticulosis. Eradication therapy might help attenuate the risk of colonic diverticulosis when Helicobacter pylori has emerged in a patient.

Abstract
BACKGROUND Sealed perforation of colonic diverticulum is a common clinical condition and may be differentiated from an underlying malignant perforation using interval endoscopy. We present an uncommon colonoscopy finding of a healed diverticular perforation, mimicking a polyp, 6 wk post-diverticulitis-something that has not been reported in literature. We aim to shed light on the likely process that resulted in the trompe l'œil after diverticulitis. This also introduces the possibility of more targeted colonic resection in the event of a similar recurrence.
CASE SUMMARY A middle-aged Chinese female presented with a 3-d history of non-colicky left iliac fossa pain. It was associated with fever (Tmax 37.6 ºC), non-bloody diarrhoea and non-bloody, non-bilious vomiting. She had a history of Type 2 diabetes mellitus, well controlled on metformin. Tenderness was noted on the left iliac fossa region with no guarding or mass. Total white cell count (11.45 × 109/L) and C-reactive protein levels (213.9 mg/L) were elevated. Computed tomography imaging of the abdomen revealed pericolonic fat stranding and extraluminal air pockets fluid density with peritoneal thickening at the sigmoid colon, likely representing a sealed perforation. Six weeks after the episode, she underwent a follow-up colonoscopy. An exophytic polypoid lesion closely associated with a diverticulum was seen in the sigmoid colon. The lesion was easily “pinched” off without much effort using endoscopic forceps and sent for histology which revealed granulation tissue suggesting a healed diverticular perforation.
CONCLUSION Granulation tissue associated with healed diverticular perforations resemble polyps. Tattooing around these sites may allow for future targeted colonic resections.

The Effects of Diverticulum Localization and Hinchey Classification on Recurrence and Complications in Acute Colonic Diverticulitis. MEDICAL BULLETIN OF SISLI ETFAL HOSPITAL 2020; 54:451-456. [PMID: 33364886 PMCID: PMC7751249 DOI: 10.14744/semb.2020.03453] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 08/19/2020] [Accepted: 10/16/2020] [Indexed: 02/07/2023]
Abstract
Objectives: Diverticular disease of the colon is a pathology that arises from outward ballooning of the mucosa due to some weakness in the muscle layer. Diverticular disease may range from symptomatic uncomplicated diverticular disease to symptomatic disease with complications, such as acute diverticulitis or diverticular bleeding. Acute colonic diverticulitis occurs in about 10- 25% of patients. Methods: In this study, 134 patients who were admitted to our emergency clinic with complaints of abdominal pain between 2016-2019 and hospitalized with the diagnosis of acute diverticulitis were included. Patients’ sex, age, presence of additional disease, increase in leukocyte and C-reactive protein (CRP), localization of diverticulitis, Hinchey classification, mean length of hospital stay and treatment were evaluated. The effects of these parameters on complications and recurrence were statistically analyzed. Results: The length of hospital stay was statistically significantly associated positively with the Hinchey classification (p<0.001). While 18 patients who were medically treated developed recurrence later, and this rate was statistically significant (p<0.001). When one of the factors, localization, which may play a role in the severity of the disease and recurrence are examined, was evaluated concerning its results in our study, we found that rectosigmoid location is an important factor for recurrence. We found that the localization in the colon and the severity of the disease were effective in the prognosis of acute diverticulitis. Conclusion: We believe that localization and the severity of the disease should be taken into consideration when planning surgery in these patients.

Prolonged Recurrent Abdominal Pain is Associated With Ongoing Underlying Mucosal Inflammation in Patients who had an Episode of Acute Complicated Diverticulitis. J Clin Gastroenterol 2019; 53:e178-e185.

Abstract
BACKGROUND Recent data suggest continuous chronic inflammation in patients after an acute diverticulitis (AD) episode. GOALS The aim of this article was to compare clinical parameters, inflammatory cytokine expression, and immune-cell infiltrates between patients after severe versus nonsevere AD, as defined by radiology examination during the acute episode. STUDY Sixteen patients, after suffering an episode of AD, were included, and, of them, 8 had severe disease. Demographic data, disease characteristics, and inflammatory markers were collected. Tissue samples from diverticular and unaffected tissue were obtained during colonoscopy. Mucosal inflammation was assessed histologically and by measuring inflammatory cytokine mRNA expression. RESULTS Clinically, continued nonspecific abdominal symptoms were significantly more prevalent among patients after severe AD compared with patients after nonsevere AD (P=0.0002). Patients after severe AD also had significantly higher C reactive protein levels (9.85±7.5 vs. 3±2.1 mg/dL; P=0.027) and tendency for higher calprotectin levels (115.7±85 vs. 35±8.7 mg/g; P=0.08). Reverse transcription polymerase chain reaction-determined cytokines levels were 5.4±4.4, 5.14±10, and 0.8±0.82 for tumor necrosis factor alpha, interleukin-6, and interleukin-1β, respectively, in affected mucosa compared with 1.06±1.57, 1.56±2.1, and 0.35±0.5, respectively, in nonaffected mucosa (P=0.01, 0.05, 0.14, respectively). Cytokine expression in patients after nonsevere AD did not differ significantly between affected and nonaffected mucosa. Histologic scores for crypt distortion, lymphoid aggregates, and lymphocyte infiltration were all significantly higher in patients after severe AD compared with patients after nonsevere AD (P<0.05 for all comparisons). CONCLUSIONS Patients after severe AD have more prolonged chronic symptoms, higher inflammatory markers, higher tissue inflammatory cytokine levels, and more inflammatory infiltrates in diverticular colonic tissue than patients after nonsevere AD. These results may contribute to patients' risk stratification and guide therapeutic decisions.

Abstract
PURPOSE Conservative treatment strategy without antibiotics in patients with uncomplicated diverticulitis (UD) has proven to be safe. The aim of the current study is to assess the clinical course of UD patients who were initially treated without antibiotics and to identify risk factors for treatment failure. METHODS A retrospective cohort study was performed including all patients with a CT-proven episode of UD (defined as modified Hinchey 1A). Only non-immunocompromised patients who presented without signs of sepsis were included. Patients that received antibiotics within 24 h after or 2 weeks prior to presentation were excluded from analysis. Patient characteristics, clinical signs, and laboratory parameters were collected. Treatment failure was defined as (re)admittance, mortality, complications (perforation, abscess, colonic obstruction, urinary tract infection, pneumonia) or need for antibiotics, operative intervention, or percutaneous abscess drainage within 30 days after initial presentation. Multivariable logistic regression analyses were used to quantify which variables are independently related to treatment failure. RESULTS Between January 2005 and January 2017, 751 patients presented at the emergency department with a CT-proven UD. Of these, 186 (25%) patients were excluded from analysis because of antibiotic treatment. A total of 565 patients with UD were included. Forty-six (8%) patients experienced treatment failure. In the multivariable analysis, a high CRP level (> 170 mg/L) was a significant predictive factor for treatment failure. CONCLUSION UD patients with a CRP level > 170 mg/L are at higher risk for non-antibiotic treatment failure. Clinical physicians should take this finding in consideration when selecting patients for non-antibiotic treatment.

Abstract
PURPOSE The aim of this study was to evaluate outpatient, non-antibiotic management in acute uncomplicated diverticulitis with regard to admissions, complications, and recurrences, within a 3-month follow-up period. METHODS A prospective, observational study in which patients with computer tomography-verified acute uncomplicated diverticulitis were managed as outpatients without antibiotics. The patients kept a personal journal, were contacted daily by a nurse, and then followed up by a surgeon at 1 week and 3 months. RESULTS In total, 155 patients were included, of which 54 were men; the mean age of the patients was 57.4 years. At the time of diagnosis, the mean C-reactive protein and white blood cell count were 73 mg/l and 10.5 × 10(9), respectively, and normalized in the vast majority of patients within the first week. The majority of the patients (97.4%) were managed successfully as outpatients without antibiotics, admissions, or complications. In only four (2.6%) patients, the management failed because of complications in three and deterioration in one. These patients were all treated successfully as inpatients without surgery. Five patients had recurrences and were treated as outpatients without antibiotics. Follow-up colonic investigations revealed cancer in two patients and polyps in 13 patients. CONCLUSION Previous results of low complication rates with the non-antibiotic policy were confirmed. The new policy of outpatient management without antibiotics in acute uncomplicated diverticulitis is now shown to be feasible, well functioning, and safe.

Abstract
OBJECTIVE To create a computable MEDication Indication resource (MEDI) to support primary and secondary use of electronic medical records (EMRs). MATERIALS AND METHODS We processed four public medication resources, RxNorm, Side Effect Resource (SIDER) 2, MedlinePlus, and Wikipedia, to create MEDI. We applied natural language processing and ontology relationships to extract indications for prescribable, single-ingredient medication concepts and all ingredient concepts as defined by RxNorm. Indications were coded as Unified Medical Language System (UMLS) concepts and International Classification of Diseases, 9th edition (ICD9) codes. A total of 689 extracted indications were randomly selected for manual review for accuracy using dual-physician review. We identified a subset of medication-indication pairs that optimizes recall while maintaining high precision. RESULTS MEDI contains 3112 medications and 63 343 medication-indication pairs. Wikipedia was the largest resource, with 2608 medications and 34 911 pairs. For each resource, estimated precision and recall, respectively, were 94% and 20% for RxNorm, 75% and 33% for MedlinePlus, 67% and 31% for SIDER 2, and 56% and 51% for Wikipedia. The MEDI high-precision subset (MEDI-HPS) includes indications found within either RxNorm or at least two of the three other resources. MEDI-HPS contains 13 304 unique indication pairs regarding 2136 medications. The mean±SD number of indications for each medication in MEDI-HPS is 6.22 ± 6.09. The estimated precision of MEDI-HPS is 92%. CONCLUSIONS MEDI is a publicly available, computable resource that links medications with their indications as represented by concepts and billing codes. MEDI may benefit clinical EMR applications and reuse of EMR data for research.

Abstract
BACKGROUND/AIMS We evaluated the efficacy of mesalamine (Asacol) in reducing gastrointestinal symptoms after an acute attack of diverticulitis. METHODS This was a 1-year double-blind, randomized, placebo-controlled study in which patients with computed tomography scan confirmed acute diverticulitis received placebo, mesalamine, or mesalamine+Bifidobacterium infantis 35624 (Align) for 12 weeks and followed for 9 additional months. Efficacy was assessed using a global symptom score (GSS) of 10 symptoms (abdominal pain, abdominal tenderness, nausea/vomiting, bloating, constipation, diarrhea, mucus, urgency, painful straining, and dysuria). Patients were required to have a GSS≥12 at baseline, including an abdominal pain score >2. RESULTS One hundred seventeen patients (placebo, 41; mesalamine, 40; mesalamine+probiotic, 36) were randomized and treated. GSS decreased in all groups during treatment without a statistically significant difference between mesalamine and placebo, however; scores were consistently lower for mesalamine at all time points. The rate of complete response (GSS=0) was significantly higher with mesalamine than placebo at weeks 6 and 52 (P<0.05), and was particularly high for rectosigmoid symptoms at weeks 6, 12, 26, and 52. Recurrence of diverticulitis was low and comparable across groups. Probiotic in combination with mesalamine did not provide additional efficacy. CONCLUSIONS In the first US randomized placebo-controlled trial of anti-inflammatory treatment after a documented case of diverticulitis, mesalamine demonstrated a consistent trend in reducing symptoms. Addition of probiotic did not increase mesalamine efficacy. This study supports further investigation into the use of anti-inflammatory agents, such as mesalamine, in the long-term management of diverticulitis. ClinicalTrials.gov NCT00554099.

Abstract
BACKGROUND Diverticulitis is an inflammatory complication to the very common condition diverticulosis. Uncomplicated diverticulitis has traditionally been treated with antibiotics with reference to the microbiology, extrapolation from trials on complicated intra-abdominal infections and clinical experience. OBJECTIVES To assess the effects of antibiotic interventions for uncomplicated diverticulitis on relevant outcome. SEARCH METHODS Studies were identified by computerised searches of the The Cochrane Library (CENTRAL), MEDLINE and EMBASE. Ongoing trials were identified and reference lists of identified trials and relevant review articles were screened for additional studies. SELECTION CRITERIA RCTs including all types of patients with a radiological confirmed diagnosis of left-sided uncomplicated diverticulitis. Interventions of antibiotics compared to any other antibiotic treatment (different regime, route of administration, dosage or duration of treatment), placebo or no antibiotics. Outcome measures were complications, emergency surgery, recurrence, late complications and duration of hospital stay and recovery of signs of infection. DATA COLLECTION AND ANALYSIS Two authors performed the searches, identification of RCTs, trial assessment and data extraction. Disagreements were resolved by discussion or involvement of a third part. Authors of trials were contacted to obtain additional data if needed or were contacted for preliminary results of ongoing trials. Effect estimates were extracted as relative risks (RR). MAIN RESULTS Three RCTs were identified. A qualitative approach with no meta analysis was performed because of variety in interventions between included studies. Interventions compared were antibiotics to no antibiotics, single to double compound antibiotic therapy and short to long IV administration. None of the studies found significant difference between the tested interventions. Risk of bias varied from low to high. The newest RCT overall had the best quality and statistical power. AUTHORS' CONCLUSIONS The newest evidence from one RCT says there is no significant difference between antibiotics versus no antibiotics in the treatment of uncomplicated diverticulitis. Previous RCTs have only suggested a non-inferiority between different antibiotic regimes and treatment lengths. This new evidence needs confirmation from more RCTs before it can be implicated safely in clinical guidelines. Ongoing RCTs will be published in the years to come and more are needed. The role of antibiotics in the treatment of complicated diverticulitis has not been investigated yet.

Abstract
BACKGROUND Diverticular disease of the colon is a common disorder, characterized by recurrent symptoms and complications such as diverticulitis, requiring hospital admissions and surgery. OBJECTIVE This study aimed to systematically review the evidence for medical therapy of diverticular disease in reducing symptoms and preventing acute diverticulitis. DATA SOURCES MEDLINE and Embase databases (1966 to February 2010). STUDY SELECTION The studies selected were prospective clinical trials on uncomplicated diverticular disease of the colon. INTERVENTIONS Four investigators independently reviewed articles, extracted data, and assessed study quality according to standardized criteria. MAIN OUTCOME MEASURES The main outcomes measured were improvement in symptoms, complete remission of symptoms, and prevention of acute diverticulitis. RESULTS We identified 31 studies, including 6 placebo-controlled trials. The methodological quality of these studies was suboptimal. Only 10 trials provided a detailed description of the patient history, 8 assessed symptoms by the use of a validated questionnaire, and 14 appropriately defined inclusion and exclusion criteria. Only one long-term double-blind placebo-controlled study was identified. This reported a significant improvement in symptoms and greater prevalence of symptom-free patients at 1 year with fiber plus rifaximin in comparison with fiber alone. The efficacy of treatment in preventing acute diverticulitis was evaluated in 11 randomized trials. Four trials compared rifaximin plus fiber vs fiber alone and failed to show a significant difference between treatments. However, cumulative data from these trials revealed a significant benefit following rifaximin and fiber (1-year rate of acute diverticulitis: 11/970 (1.1%) vs 20/690 (2.9%); P = .012), but with a number needed to treat of 57, to prevent an attack of acute diverticulitis. LIMITATIONS : Heterogeneity of the study design, patients' characteristics, regimens and combination of studied treatment, and outcome reporting precluded the pooling of results and limited interpretation. CONCLUSIONS The treatment for diverticular disease relies mainly on data from uncontrolled studies. Treatment showed some evidence of improvement in symptoms, but its role in the prevention of acute diverticulitis remains to be defined.

Is conservative treatment with antibiotics the correct strategy for management of right colonic diverticulitis?: a prospective study. JOURNAL OF THE KOREAN SOCIETY OF COLOPROCTOLOGY 2011; 27:188-93. [PMID: 21980589 PMCID: PMC3180599 DOI: 10.3393/jksc.2011.27.4.188] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/10/2011] [Accepted: 08/16/2011] [Indexed: 11/19/2022]
Abstract
Purpose The goals of this study were to identify whether conservative treatment with antibiotics in right colonic diverticulitis (RCD) patients, our empirical method used until now, is adequate and to determine how the natural history of RCD is affected by conservative treatment. Methods This study was designed as a case-control study. Group I was comprised of 12 patients who were managed conservatively, and clinical data were retrospectively collected. In group II, a total of 49 patients, diagnosed by using diagnostic criteria for RCD and managed conservatively, were prospectively included. Results The period of fasting was 2.7 days, and the hospital stay was 4.6 days in all patients. The intravenous and the oral antibiotic periods were 3.8 days and 9.8 days, respectively. There were no statistically significant differences in treatment results between the two groups except the duration of fasting and the hospitalization, and there were no complications under conservative treatment. Eight patients (13.1%) had recurrent diverticulitis during the follow-up period. The recurrence risk showed no significant difference between the groups. The RCD-free period after management was 60.1 months, and patients with recurrent RCD were treated by conservative treatment or laparoscopic surgery. Conclusion Conservative treatment with antibiotics is the optimal treatment of choice for RCD and shows no increase in complications.

Abstract
In this study, we have used monocyte-derived dendritic cells (DCs) to design a screening model for the selection of microorganisms with the ability to suppress DC-secreted IL-12p70, a critical cytokine for the induction of T-helper cell type 1 immune responses under inflammatory conditions. By the treatment of DCs with cocktails containing TLR agonists and proinflammatory cytokines, the cells increased the secretion of the Th1-promoting cytokine IL-12p70. Clinically used probiotics were tested for their IL-10- and IL-12p70-stimulating properties in immature DCs, and showed a dose-dependent change in the IL-10/IL-12p70 balance. Lactobacillus acidophilus NCFM(™) and the probiotic mixture VSL#3 showed a strong induction of IL-12p70, whereas Lactobacillus salivarius Ls-33 and Bifidobacterium infantis 35624 preferentially induced IL-10. Escherichia coli Nissle 1917 induced both IL-10 and IL-12p70, whereas the probiotic yeast Saccharomyces boulardii induced low levels of cytokines. When combining these microorganisms with the Th1-promoting cocktails, E. coli Nissle 1917 and B. infantis 35624 were potent suppressors of IL-12p70 secretion in an IL-10-independent manner, indicating a suppressive effect on Th1-inducing antigen-presenting cells. The present model, using cocktail-stimulated DCs with potent IL-12p70-stimulating capacity, may be used as an efficient tool to assess the anti-inflammatory properties of microorganisms for potential clinical use.

Abstract
BACKGROUND AND AIMS Information about faecal calprotectin (FC) in colonic diverticular disease (DD) are lacking. We assessed FC in colonic DD, comparing it with irritable bowel syndrome (IBS) patients and healthy controls. Moreover, we compared FC levels in different degrees of DD and assessed FC in symptomatic DD before and after treatment. MATERIALS AND METHODS Forty-eight consecutive patients with a new endoscopic diagnosis of DD (16 with asymptomatic diverticulosis, 16 with symptomatic uncomplicated DD, 16 with acute uncomplicated diverticulitis), 16 healthy controls, and 16 IBS patients were studied. FC was assessed by semi-quantitative method and compared with histological inflammation. Moreover, FC was reassessed in symptomatic DD after 8 weeks of treatment. RESULTS/FINDINGS FC was not increased in healthy controls and IBS patients. No difference was found between asymptomatic diverticulosis, healthy controls, and IBS patients (p = n.s.). We found higher FC values in acute uncomplicated diverticulitis (p < 0.0005) and in symptomatic uncomplicated DD (p < 0.005) than in healthy controls and in IBS patients. FC values correlated with inflammatory infiltrate (p < 0.0005). FC decreased after treatment to normal values both in acute uncomplicated diverticulitis (p < 0.0005) and in symptomatic uncomplicated DD (p < 0.005) after treatment. INTERPRETATIONS/CONCLUSIONS: FC may be useful to detect colonic inflammation in DD and in distinguishing symptomatic DD from IBS, as well as in assessing response to therapy in DD.

Abstract
The term "diverticulitis" indicates the inflammation of a diverticulum or diverticula, which is accompanied by detectable or microscopical perforation. Diverticulitis is a common condition with an estimated incidence of 25%. At present, elective sigmoid resection is recommended after 2 episodes of uncomplicated diverticulitis to prevent the serious complications of recurrent colonic diverticulitis. This guideline has been based on the assumption that recurrent episodes (2 or more) of diverticulitis will lead to complicated diverticulitis and higher mortality. The data to support this assumption are based on only a few small studies. Advances in diagnostic modalities, medical therapy, and surgical techniques over the past 2 decades have changed both the management and outcomes of diverticulitis. Many authors have shown that patients treated nonoperatively have a low risk of recurrent disease and would be expected to do well without elective colectomy.

Abstract
BACKGROUND AND AIMS Increased epithelial cell proliferation may be detected in diverticular disease, but antibiotics have failed in reducing it. We assess therefore the effect of mesalazine on epithelial cell proliferation in diverticular disease. METHODS A prospective study was conducted on 20 consecutive patients with a new endoscopic diagnosis of symptomatic uncomplicated diverticular disease. The patients were treated with mesalazine 1.6 mg/day for 1 year. The Ki-67 antigen index of the whole crypt and in the upper third was separately evaluated before and after starting the treatment. RESULTS Cell proliferation index was higher in diverticular disease patients than healthy controls both in the whole crypt (median 6.7%, range 2-9% vs. median 1.6%, range 1-3%, p=0.001) and in the upper third of the crypt (median 6.8%, range 2-8% vs. median 1.8%, range 1-3%, p=0.001). Cell proliferation decreased throughout the follow-up. In the whole crypt it was 6.7% at entry and 3.8% at the end of treatment (p<0.005), whereas it was 6.8% at entry and 2.9% at the end of treatment in the upper third of the crypt (p<0.005). CONCLUSIONS We found mesalazine effective in reducing the colonic cell proliferation in long-term treatment for colonic diverticular disease.

Abstract
Balsalazide is a 5-amino salicylic acid prodrug well-tolerated and effective in treating acute ulcerative colitis. VSL[sharp]3, a high-potency probiotic mixture, has proved to be effective in preventing flare-ups of chronic pouchitis and in obtaining remission of mild-to-moderate ulcerative colitis. Recent studies found the association of low-dose balsalazide/VLS no. 3 effective in treating mild-to-moderate ulcerative colitis and in preventing the recurrence of uncomplicated diverticulitis of the colon. In this paper, the framework for using this association to treat ulcerative colitis or to prevent the recurrence of colonic diverticulitis is reviewed, and 2 studies on this therapeutic approach are briefly summarized.

Abstract
GOAL The aim of this study was to assess and grade the mucosal inflammatory infiltrate in different degrees of diverticular disease (DD) and to compare them with healthy matched controls. BACKGROUND Mucosal inflammation in colonic DD has never been investigated. In particular, it is unknown whether inflammation may be found in every degree of DD. MATERIALS AND METHODS Thirty consecutive patients with a new endoscopic diagnosis of DD (10 with asymptomatic diverticulosis, 10 with symptomatic uncomplicated DD, and 10 with acute uncomplicated diverticulitis) and 10 healthy controls were studied. RESULTS A neutrophilic inflammatory infiltrate was found only in acute uncomplicated diverticulitis (overall score, 26). The mean lymphocytic cell density was significantly higher in symptomatic DD (median lymphocytic density, 7) and acute uncomplicated diverticulitis (median lymphocytic density, 11). Subdividing the patients according to different degrees of DD, we found higher lymphocytic cell density even in asymptomatic diverticulosis (median lymphocytic density, 6.5) than healthy controls (median lymphocytic density, 4; P<0.02). CONCLUSIONS We found an increased inflammatory infiltrate in DD according to the degree of the disease and higher than healthy controls. Moreover, also asymptomatic diverticulosis shows higher inflammatory cell density than controls.

Abstract
BACKGROUND Complicated diverticular disease of the colon imposes a serious risk to patient's life, challenge to surgeons and has cost implications for health authority. The aim of this study is to evaluate the management outcome of complicated colonic diverticular disease in a district hospital and to explore the current strategies of treatment. METHODS This is a retrospective study of all patients who were admitted to the surgical ward between May 2002 and November 2006 with a diagnosis of complicated diverticular disease. A proforma of patients' details, admission date, ITU admission, management outcomes and the follow up were recorded from the patients case notes and analyzed. The mean follow-up was 34 months (range 6-60 months) RESULTS The mean age of patients was 72.7 years (range 39-87 years). Thirty-one men (28.18 %) and Seventy-nine women (71.81%) were included in this study. Male: female ratio was 1:2.5.Sixty-eight percent of patients had one or more co-morbidities. Forty-one patients (37.27%) had two or more episodes of diverticulitis while 41.8% of them had no history of diverticular disease.Eighty-six percent of patients presented with acute abdominal pain while bleeding per rectum was the main presentation in 14%. Constipation and erratic bowel habit were the commonest chronic symptoms in patients with history of diverticular disease. Generalized tenderness was reported in 64.28% while 35.71% have left iliac fossa tenderness. Leukocytosis was reported in 58 patients (52.72%).The mean time from the admission until the start of operative intervention was 20.57 hours (range 4-96 hours). Perforation was confirmed in 59.52%. Mortality was 10.90%. Another 4 (3.63%) died during follow up for other reasons. CONCLUSION Complicated diverticular disease carries significant morbidity and mortality. These influenced by patient-related factors. Because of high mortality and morbidities, we suggest the need to target a specific group of patients for prophylactic resection.

Abstract
BACKGROUND Cyclic administration of rifaximin in association with dietary fibre achieves symptomatic relief in uncomplicated diverticular disease (DD) by means of a still undefined mechanism. AIM To investigate the effects of a combination of rifaximin and fibre on both hydrogen production by intestinal microflora and oro-anal transit time. METHODS In a controlled, double-blind crossover trial, 64 patients with uncomplicated DD were given bran (20 g/day) and randomly treated with rifaximin (1200 mg/day) or a placebo for 14 days. Evaluation was based on clinical status, breath test, oro-anal transit time and faecal weight. RESULTS The global symptomatic score was significantly reduced after rifaximin (7.1 +/- 4.1 to 4.1 +/- 3.3; P < 0.005) but not after placebo (6.8 +/- 3.8 to 6.1 +/- 3.5). Hydrogen production significantly increased after placebo from 198 +/- 134 to 267 +/- 161 ppm/min, while Rifaximin reduced it from 222 +/- 187 to 166 +/- 131 ppm/min (P = 0.05). The total oro-anal transit time decreased from 56.1 +/- 28.2 to 51.3 +/- 28.0 h in placebo and from 54.4 +/- 31.9 to 45.1 +/- 32.4 h (P < 0.05) in rifaximin-treated patients. CONCLUSIONS The administration of rifamixin improves the benefits of dietary fibre in uncomplicated DD by preventing its bacterial degradation.

Abstract
Diverticular disease of the colon is among the most common diseases of westernised and industrialised countries. Its prevalence is approximately 5-10% of people up to 50 years of age, 30% of those > 50 years of age, and 50% of those > 70 years of age, and 66% of people > 85 years of age. Standard medical therapies with antibiotics are still the recommended treatment. However, changing concepts and new therapies recently found that anti-inflammatory agents, such as mesalazine (alone or in combination with antibiotics) and probiotics, may be useful in shortening the course of the disease and perhaps in preventing recurrences.

Abstract
Forty consecutive patients affected by recurrent attacks of symptomatic uncomplicated diverticular disease of the colon were evaluated to investigate the effectiveness of 2 different mesalazine therapeutic schedules in preventing recurrence of the disease. The patients were randomly enrolled and treated with mesalazine 1.6 g/d (group A) or mesalazine 1.6 g/d 10 days per month (group B). Thirty-four patients completed the study (85%): 3 (7.5%, 1 in group A and 2 in group B) were lost to follow-up, 2 (5%, both group B) were withdrawn from the study for protocol violation, and 1 (2.5%) for hospital admission for stroke (group A). Twenty-three patients (67.65%) were symptom free after 24 months of treatment (overall symptomatic score, 0): 14 of 18 in group A (per-protocol, 77.78%; intention to treat, 70% [95% confidence interval [CI], 61.5-91.8]), 9 of 16 in group B (per protocol, 56.25%; intention to treat, 45% [95% CI, 61.5-91.8]; P < 0.05). Four patients (10%) improved, but were not completely symptom free. Six patients (15%) showed recurrence of symptoms: 1 in group A (5.56%) and 5 in group B (31.25%; P < 0.005; overall symptomatic score, 68). Daily mesalazine supplying seems to be more effective than cyclic supplying in maintaining remission in recurrent symptomatic uncomplicated diverticular disease.

Abstract
PURPOSE Acute diverticulitis is the most common presentation of diverticular disease; however, no published guidelines for management are available in the United Kingdom. This survey was designed to assess the current United Kingdom regional practice compared with the guidelines published by The American Society of Colon and Rectal Surgeons. METHODS A questionnaire survey focused on the management of acute diverticulitis was sent to all consultants, specialist registrars, and staff-grade surgeons in general surgery in one United Kingdom region. RESULTS Eighty-two questionnaires were returned (80 percent). A majority (80 percent) would request routine blood tests, abdominal, and erect chest x-rays on arrival. Pethidine (56 percent) was the preferred analgesic, followed by morphine (40 percent). Ninety-four percent used an antibiotic combination of second/third-generation cephalosporin and metronidazole. Computerized tomography was the most commonly used initial investigation (42 percent). Forty percent use barium enema and 31 percent use a combination of barium enema and sigmoidoscopy as follow-up investigations. In patients older than aged 50 years, elective resection would be considered by a majority (51 percent) only when complications arose. In those aged 50 years or younger, 35 percent would resect only if complications arose with only 6 percent after a single episode of acute diverticulitis. CONCLUSIONS There are major differences in the management of patients with acute diverticulitis in our current practice in one United Kingdom region compared with the guidelines published by The American Society of Colon and Rectal Surgeons, which are based on published literature. There is an urgent need to establish similar guidelines in the United Kingdom to improve the clinical outcome of patients with such a common condition.

Abstract
Diverticular disease includes a spectrum of conditions sharing the underlying pathology of acquired diverticula of the colon: symptomatic uncomplicated diverticular disease, recurrent symptomatic uncomplicated diverticular disease, and complicated diverticular disease. Goals of therapy in diverticular disease should be to improve symptoms and to prevent recurrent attacks in symptomatic uncomplicated diverticular disease, and to prevent the complications of disease such as diverticulitis. Inflammation seems to play a key role in all forms of the disease. This is the rationale for the use of anti-inflammatory drugs such as mesalazine. Inflammation in such diseases seems to be generated by a heightened production of proinflammatory cytokines, reduced anti-inflammatory cytokines, and enhanced intramucosal synthesis of nitric oxide. The mechanisms of action of mesalazine are not yet well understood. It is an anti-inflammatory drug that inhibits factors of the inflammatory cascade (such as cyclooxygenase) and free radicals, and has an intrinsic antioxidant effect. Some recent studies confirm the efficacy of mesalazine in diverticular disease both in relief of symptoms in symptomatic uncomplicated forms and in prevention of recurrence of symptoms and main complications.

Abstract
Colonic diverticulosis is among the most common diseases of developed countries. Its prevalence is approximately 5 - 10% of the population by age 50, and 30, 50 and 66% of those > 50, > 70 and > 85years of age, respectively. Antibiotics have been successfully used in the treatment of uncomplicated diverticular disease; however, the use of mesalazine (alone or in combination with antibiotics) in treating uncomplicated diverticulitis has been successfully developed in recent years. Indeed, mesalazine (with or without antibiotics) showed significant superiority in improving the severity of symptoms, bowel habits, and in preventing symptomatic recurrence of diverticulitis over antibiotics alone. More-over, in light of some preliminary results, it is probable that the association of mesalazine with probiotics may in the future be the first-choice treatment for mild-to-moderate uncomplicated attacks of acute diverticulitis.

Abstract
GOAL This study assesses the epithelial cell proliferation in different degrees of diverticular disease and compares this with two different control groups. BACKGROUND Hyperproliferation of the colonic mucosa has been recently described in diverticular disease (DD), but it is unknown whether this finding is present in every degree of DD. PATIENTS AND METHODS Thirty consecutive patients with a new endoscopic diagnosis of DD (10 with asymptomatic diverticulosis, 10 with symptomatic uncomplicated DD, and 10 with acute uncomplicated diverticulitis) were enrolled. Ten matched healthy people and 10 patients with ulcerative colitis (UC) (5 with UC in remission and 5 with active UC) were enrolled as control groups. The Ki-67 antigen index of the whole crypt and the upper third was separately evaluated. RESULTS Ki-67 index of the whole crypt and the upper third of the crypt was significantly higher in all degrees of DD compared with the healthy control group. In particular, asymptomatic diverticulosis showed a threefold higher Ki-67 index compared with that of the healthy control group (5.4% and 5.6% vs. 1.6% and 1.8%, respectively, P = 0.005), and similar to that of UC in remission (5.4% and 5.6% vs. 5.9% and 5.8%, respectively, P = not significant). CONCLUSIONS We found an upward shifting of cellular proliferation of the colonic mucosa in patients with different degrees of DD. In particular, asymptomatic diverticulosis seems to show the same risk for colonic carcinoma as that of UC.

Abstract
GOALS To investigate the effectiveness and safety of mesalazine, with or without Lactobacillus casei, in preventing recurrence of symptomatic diverticular disease of the colon. BACKGROUND Both mesalazine and probiotics showed recently their effectiveness in obtaining remission of symptomatic uncomplicated diverticular disease of the colon. Consistent data are not available on the optimal therapy to prevent recurrence of symptomatic diverticular disease of the colon. STUDY Multicenter, prospective, randomized, open-label study. Ninety consecutive patients (36 men, 54 women, mean age 67.5 y, range 39 to 84 y), previously affected by symptomatic uncomplicated diverticular disease of the colon (remission obtained with rifaximin 800 mg/d plus mesalazine 2.4 g/d for 10 d, followed by mesalazine 1.6 g/d for 8 wk), were enrolled in a 12-month follow-up. The following symptoms were assessed at entry and through follow-up by using a quantitative scale: (1) constipation, (2) diarrhea, (3) abdominal pain, (4) rectal bleeding, and (5) mucus with the stools. After recruitment, the patients were randomly assigned to one of the following 3 groups: mesalazine 1.6 g/d (group M), L. casei DG 16 billion/d for 15 d/mo (group L); mesalazine 1.6 g/d+L. casei DG 16 billion/d for 15 d/mo (group LM). RESULTS Eighty-five patients completed the study (94.5%): 2 patients (2.22%, 1 of group M and 1 of group LM) were withdrawn from the study for protocol violation and 1 (1.11%) for hospital admission due to acute pulmonary disease (group L); 2 patients (2.22%) were lost to follow-up. Seventy-five patients (88.2%) were symptom free after the 12th month of treatment (overall symptomatic score: (0): 23/27 patients of group M [on intention to treat: 76.7% confidence interval (CI 95%: 61.5 to 91.8)], 23/29 of group L [on intention to treat: 76.7% (CI 95%: 61.5 to 91.8)], 29/29 of group LM [on intention to treat: 96% (CI 95%: 94.2 to 100)] (P < 0.05). Only 10 patients (11.1%) showed recurrence of symptoms (overall symptomatic score: 68). CONCLUSIONS Both mesalazine and L. casei DG seem to be effective in preventing recurrence of symptomatic uncomplicated diverticular disease of the colon, but their association seems to be more promising in this field.

Abstract
Lactose malabsorption (LM) may be secondary to several small bowel diseases, and small intestinal overgrowth (SIBO) may be one of them. We looked for a correlation between symptomatic diverticular disease of the colon and LM and assessed whether this correlation may be related to SIBO. Ninety consecutive patients (pts; 39 males, 51 females; mean age, 67.2 years; range, 32-91 years) affected by symptomatic uncomplicated diverticular disease of the colon were evaluated to assess orocecal transit time (OCTT), SIBO, and LM by lactulose and lactose H2 breath test (H2-BT) at entry and after 8 weeks of treatment. OCTT was delayed in 67 of 90 pts (74.44%). Fifty-three of 90 pts (58.88%) showed SIBO, and OCTT was normal in 23 of 90 pts (25.56%). LM was diagnosed in 59 of 90 pts (65.55%): 49 of 59 (71.74%) were simultaneously affected by SIBO and delayed OCTT (and thus 49 of 53 pts [92.45%] with delayed OCTT and SIBO were affected by LM); 3 of 59 pts (5.09%) showed only delayed OCTT; 7 of 59 pts (11.86%) did not show either SIBO or delayed OCTT. The association of LM and SIBO was statistically significant (P < 0.001). Seventy-nine of 86 pts (91.86%) showed normal OCTT, while OCTT remained prolonged but shorter in the remaining 7 pts (8.14%). SIBO was eradicated in all pts completing the study, while a new lactulose H2-BT showed persistence of SIBO in one pt with recurrence of symptomatic diverticular disease. Forty-seven of 59 pts (79.66%) had a normal lactose H2-BT (P < 0.002), while 12 of 59 pts (20.34%) showed persistence of LM. LM disappeared in 46 of 49 pts (93.88%) concurrently with normalization of OCTT and eradication of SIBO (P < 0.002); it also disappeared in 1 of 3 pts (33.33%) previously affected by delayed OCTT (without SIBO) and LM concurrently with normalization of OCTT. On the contrary, it persisted in all pts with normal OCTT and absence of SIBO. Moreover, it persisted also in the pt with recurrence of symptomatic diverticular disease and persistence of SIBO. In conclusion, most pts affected by symptomatic uncomplicated diverticular disease of the colon showed LM, and in more than 70% of cases it disappeared after successful treatment of the colonic disease.

Abstract
BACKGROUND A higher risk of both advanced adenoma and carcinoma occurs in the sigmoid colon of patients with diverticular disease, for which bacterial carcinogens have been claimed to play a role. AIM To assess epithelial cell proliferation in colonic mucosa of diverticular disease patients before and after rifaximin treatment. METHODS Twelve consecutive patients with a new endoscopic diagnosis of left-sided diverticular disease and 12 matched controls were enrolled. Epithelial cell proliferation in the sigmoid mucosa was assessed by using proliferating cell nuclear antigen. The proliferating cell nuclear antigen index of the whole crypt and of the upper third was separately evaluated before and after 10-day rifaximin (400 mg b.d.) therapy. RESULTS Proliferating cell nuclear antigen index in the upper third of the crypt was significantly higher in the diverticular patients (median: 25, range: 14-32) as compared with controls (median: 15, range: 5-20) (P = 0.038), and it was not reverted by rifaximin therapy. No difference of the proliferating cell nuclear antigen index of the whole crypt was detected between cases (median: 27, range: 23-44) and controls (median: 25, range: 18-42) (P = 0.6). CONCLUSIONS Our data showed an upward shifting of cellular proliferation in the sigmoid mucosa of patients with diverticular disease. Because of rifaximin failure in reversing this alteration, factors other than the bacterial load should probably be investigated.

Abstract
AIM: Small intestinal bacterial overgrowth (SIBO) may contribute to the appearance of several gastrointestinal nonspecific symptoms. Acute diverticulitis is affected by some similar symptoms and bacterial colonic overgrowth. We assessed the prevalence of SIBO in acute uncomplicated diverticulitis and evaluated its influence on the clinical course of the disease.
METHODS: We studied 90 consecutive patients (39 males, 51 females, mean age 67.2 years, range 32-91 years). Sixty-one patients (67.78%) and 29 patients (32.22%) were affected by constipation-or diarrhea-prevalent diverticulitis respectively. All subjects were investigated by lactulose H2-breath test at the entry and at the end of treatment. We also studied a control group of 20 healthy subjects (13 males, 7 females, mean age 53 years, range 22-71 years).
RESULTS: Oro-cecal transit time (OCTT) was delayed in 67/90 patients (74.44%) (range 115-210 min, mean 120 min). Fifty-three of ninety patients (58.88%) showed SIBO, while OCTT was normal in 23/90 patients (25, 56%). In the control group, the mean OCTT was 88.2 min (range 75-135 min). The difference between diverticulitic patients and healthy subjects was statistically significant (P<0.01). OCTT was longer in constipation-prevalent disease than in diarrhea-prevalent disease [180.7 min (range 150-210 min) vs 121 min (range 75-180 min) (P<0.001)], but no difference in bacterial overgrowth was found between the two forms of diverticulitis.After treatment with rifaximin plus mesalazine for 10 d, followed by mesalazine alone for 8 wk, 70 patients (81.49%) were completely asymptomatic, while 16 patients (18.60%) showed only slight symptoms. Two patients (2.22%) had recurrence of diverticulitis, and two other patients (2.22%) were withdrawn from the study due to side-effects. Seventy-nine of eighty-six patients (91.86%) showed normal OCTT (range 75-105 min, mean 83 min), while OCTT was longer, but it was shorter in the remaining seven (8.14%) patients (range 105-115 min, mean of 110 min). SIBO was eradicated in all patients, while it persisted in one patient with recurrence of diverticulitis.
CONCLUSION: SIBO affects most of the patients with acute diverticulitis. SIBO may worsen the symptoms of patients and prolong the clinical course of the disease, as confirmed in the case of persistence of SIBO and diverticulitis recurrence. In this case, we can hypothesize that bacteria from small bowel may re-colonize in the colon and provoke recurrence of symptoms.
