Int J Surg 2023; 109:689-697. [PMID: 37010145 PMCID: PMC10389554 DOI: 10.1097/js9.0000000000000213] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2022] [Accepted: 01/05/2023] [Indexed: 04/04/2023]
Abstract
BACKGROUND There are no specific recommendations regarding the optimal management of this group of patients. The World Society of Emergency Surgery suggested a nonoperative strategy with antibiotic therapy, but this was a weak recommendation. This study aims to identify the optimal management of patients with acute diverticulitis (AD) presenting with pericolic free air with or without pericolic fluid. METHODS A multicenter, prospective, international study of patients diagnosed with AD and pericolic-free air with or without pericolic free fluid at a computed tomography (CT) scan between May 2020 and June 2021 was included. Patients were excluded if they had intra-abdominal distant free air, an abscess, generalized peritonitis, or less than a 1-year follow-up. The primary outcome was the rate of failure of nonoperative management within the index admission. Secondary outcomes included the rate of failure of nonoperative management within the first year and risk factors for failure. RESULTS A total of 810 patients were recruited across 69 European and South American centers; 744 patients (92%) were treated nonoperatively, and 66 (8%) underwent immediate surgery. Baseline characteristics were similar between groups. Hinchey II-IV on diagnostic imaging was the only independent risk factor for surgical intervention during index admission (odds ratios: 12.5, 95% CI: 2.4-64, P =0.003). Among patients treated nonoperatively, at index admission, 697 (94%) patients were discharged without any complications, 35 (4.7%) required emergency surgery, and 12 (1.6%) percutaneous drainage. Free pericolic fluid on CT scan was associated with a higher risk of failure of nonoperative management (odds ratios: 4.9, 95% CI: 1.2-19.9, P =0.023), with 88% of success compared to 96% without free fluid ( P <0.001). The rate of treatment failure with nonoperative management during the first year of follow-up was 16.5%. CONCLUSION Patients with AD presenting with pericolic free gas can be successfully managed nonoperatively in the vast majority of cases. Patients with both free pericolic gas and free pericolic fluid on a CT scan are at a higher risk of failing nonoperative management and require closer observation.

Machine Learning Model for Outcome Prediction of Patients Suffering from Acute Diverticulitis Arriving at the Emergency Department-A Proof of Concept Study. Diagnostics (Basel) 2021; 11:diagnostics11112102. [PMID: 34829448 PMCID: PMC8625306 DOI: 10.3390/diagnostics11112102] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2021] [Revised: 11/08/2021] [Accepted: 11/11/2021] [Indexed: 12/23/2022] Open
Abstract
Background & Aims: We aimed at identifying specific emergency department (ED) risk factors for developing complicated acute diverticulitis (AD) and evaluate a machine learning model (ML) for predicting complicated AD. Methods: We analyzed data retrieved from unselected consecutive large bowel AD patients from five hospitals from the Mount Sinai health system, NY. The study time frame was from January 2011 through March 2021. Data were used to train and evaluate a gradient-boosting machine learning model to identify patients with complicated diverticulitis, defined as a need for invasive intervention or in-hospital mortality. The model was trained and evaluated on data from four hospitals and externally validated on held-out data from the fifth hospital. Results: The final cohort included 4997 AD visits. Of them, 129 (2.9%) visits had complicated diverticulitis. Patients with complicated diverticulitis were more likely to be men, black, and arrive by ambulance. Regarding laboratory values, patients with complicated diverticulitis had higher levels of absolute neutrophils (AUC 0.73), higher white blood cells (AUC 0.70), platelet count (AUC 0.68) and lactate (AUC 0.61), and lower levels of albumin (AUC 0.69), chloride (AUC 0.64), and sodium (AUC 0.61). In the external validation cohort, the ML model showed AUC 0.85 (95% CI 0.78–0.91) for predicting complicated diverticulitis. For Youden’s index, the model showed a sensitivity of 88% with a false positive rate of 1:3.6. Conclusions: A ML model trained on clinical measures provides a proof of concept performance in predicting complications in patients presenting to the ED with AD. Clinically, it implies that a ML model may classify low-risk patients to be discharged from the ED for further treatment under an ambulatory setting.

Abstract
The prevalence of urinary incontinence and other lower urinary tract symptoms increases with older age. These symptoms are more noticeable in men after the seventh decade of life and in women after menopause. Constipation and fecal incontinence are major causes of symptoms in elderly patients and can significantly impair quality of life. This article summarizes the current literature regarding the occurrence and implications of lower urinary tract and bowel symptoms in the geriatric population.

Development and validation of a diverticular clinical score for symptomatic uncomplicated diverticular disease after acute diverticulitis in a prospective patient cohort. Therap Adv Gastroenterol 2020; 13:1756284820913210. [PMID: 32523619 PMCID: PMC7236576 DOI: 10.1177/1756284820913210] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/12/2019] [Accepted: 02/13/2020] [Indexed: 02/04/2023] Open
Abstract
BACKGROUND Following an attack of acute diverticulitis (AD), many patients continue to suffer from a complex of symptoms, titled 'symptomatic uncomplicated diverticular disease (SUDD)'. To date, there is no validated clinical score for standardized assessment of patients with SUDD, thereby hampering the interpretation of observational studies and the conductance of clinical trials.We aimed to develop a validated SUDD clinical score. METHODS Data from previous prospective study of patients after AD was used to devise the score's first version. Validation was first performed using a focus group of patients after AD SUDD who underwent a structured cognitive personal interview. Thereafter, the diverticular clinical score (DICS) was applied for a second validation cohort. DICS scores of validation cohort were compared with physicians' global assessment for disease severity and inflammatory markers. RESULTS In DICS second validation using 48 patients prospectively recruited after AD SUDD, a correlation matrix demonstrated strong correlation between total questionnaire's score and the presence of elevated inflammatory markers (ρ = 0.84). Mean score in patients with elevated inflammatory markers compared with those without inflammation was 17.8 versus 6.2, respectively, p < 0.001. Cronbach's α for measuring internal consistency was 0.91. DICS discriminated accurately between patients with/without active disease, as gauged by the physicians global assessment (area under the curve receiver operating characteristic = 0.989). CONCLUSIONS Patients suffering from post-AD SUDD exhibit a wide range of symptoms. The newly developed DICS accurately and reproducibly quantitates SUDD-related symptom severity. The DICS may prove useful for monitoring SUDD in clinical practice and in research settings, as well as facilitating patient stratification and therapeutic decisions.

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
GOALS The goal is to find the risk of colorectal cancer after an episode of acute diverticulitis in conservatively treated patients. Secondly, to determine the benefit of colonoscopy in these patients. BACKGROUND In the Netherlands, it is a common practice to routinely perform a colonoscopy after an episode of conservatively treated diverticulitis to exclude a malignancy. Yet according to the Dutch guidelines, these patients should not undergo a colonoscopy on a routine basis. The aim of this study is to determine the benefit of a colonoscopy in patients who have been treated for diverticulitis conservatively. STUDY This retrospective study includes patients who were diagnosed with acute diverticulitis (Hinchey 0 and I) and were treated conservatively, with or without antibiotics. Only patients who underwent colonoscopy were included for analysis. In addition, the outcome (yes or no colorectal cancer) of colonoscopy was analyzed according to patients' presentation of alarm symptoms for colorectal cancer. RESULTS Between January 2008 and June 2013, 977 patients were treated conservatively for an episode of acute diverticulitis. Of those, 645 underwent colonoscopy during follow-up. Alarm symptoms for colorectal cancer were present in 205 patients. Nine of them were diagnosed with colorectal cancer (4.4%) versus 1 patient (0.2%, P=0.0002) in the group without alarm symptoms (N=440). CONCLUSIONS This study confirms that routine colonoscopy is not indicated after acute diverticulitis which has been treated conservatively in a large series. Only in case of alarm symptoms a colonoscopy is mandatory, but even then the actual finding of a colorectal cancer is rare.

Abstract
BACKGROUND Data on percutaneous drainage followed by observation for diverticular abscess is scant. OBJECTIVE The aim of this study is to assess outcomes of percutaneous drainage alone in the management of peridiverticular abscess. DESIGN This is a retrospective study from a prospectively collected database. SETTING This study was conducted in a high-volume, specialized colorectal surgery unit. PATIENTS All patients with a diverticular abscess of at least 3 cm in diameter, treated between 2001 and 2012, who had prohibitive comorbidities or refused surgery after percutaneous drainage were included. MAIN OUTCOME MEASURES The primary outcome measured was the treatment of diverticular abscess with percutaneous drainage alone. RESULTS A total of 18 patients (11 surgery refusal, 7 comorbidity) were followed up until death, surgery for recurrent diverticulitis, or for a median of 90 (17-139) months. The median abscess size was 5 (3.8-10) cm, and the location was pelvic in 8 cases and intra-abdominal in 10. The mean duration of drainage was 20 ± 1.3 days, with the exception of 2 patients who only had aspiration of the abscess because of technical difficulty in drain placement. Three patients died of preexisting comorbidities between 2 and 8 months after percutaneous drainage. Seven of the surviving patients (7/15) experienced recurrent diverticulitis; 3 of these patients underwent surgery between 7 months and 7 years after the index percutaneous drainage. Of the remaining 4 cases of recurrence, one abscess was treated with repeat percutaneous drainage alone and 3 patients had uncomplicated diverticulitis treated with antibiotics. There were no significant associations between long-term failure of percutaneous drainage and the location of the abscess (p = 0.54) or previous episodes of diverticulitis (p = 0.9). LIMITATIONS This study was limited because of its retrospective nature, its nonrandomized design, and its small sample size. CONCLUSIONS Percutaneous drainage alone was successful in avoiding surgery in the majority of this selected patient population with sigmoid diverticular abscess. Future studies should assess the appropriate indications for a more liberal use of percutaneous drainage not followed by elective surgery.

Abstract
BACKGROUND Acute diverticulitis (AD) is the most common complication of diverticular disease and affects 10% to 25% of patients. Data regarding the natural history of AD are lacking. GOALS Our aim was to prospectively assess the occurrence of recurrent attacks, surgeries, and accompanying symptoms in patients who were hospitalized with AD. STUDY All patients hospitalized with first episode of AD between January 2000 and November 2006 were enrolled. Patients were followed up both during hospitalization and after discharge. Data regarding operations and complications were collected. Special attention was paid to patients younger than 45 years of age and compared with older patients. RESULTS A total of 261 patients were identified-of them 103 were men. Thirty patients (11.5%) were 45 years old or younger. The mean follow-up period was 88±22 months (range, 52 to 184 mo). Younger patients experienced significantly more complications during hospitalization (37% vs. 12.5%, P=0.001) and underwent more often a sigmoidectomy in the follow-up period (42.3% vs. 18.3%, P=0.01). Older patients tended to be more often asymptomatic after discharge (P=0.053). The average time from index hospitalization to the sigmoidectomy was 18.17±23.35 months (range, 1 to 120 mo). The odds ratio for sigmoidectomy after complicated AD is 16.2 (95% confidence interval, 13.4 to 19.6). Age did not affect the risk for surgery. CONCLUSIONS Younger patients with AD experience more complications during hospitalization and undergo surgery after discharge more frequently. Complicated AD at index hospitalization is a risk factor for sigmoidectomy. Our data can help predict the outcome of patients suffering from AD and enable tailoring an individual treatment.

Abstract
PURPOSE Perforated diverticulitis (PD) remains a serious acute abdominal condition. The aim of this study was to evaluate indications for emergency surgery in patients ≥80 years of age with PD. METHOD Twenty patients ≥80 years of age and 28 younger patients who underwent emergency surgery for PD from January 2002 to December 2011 were studied. The demographics and postoperative outcomes were compared. RESULTS The preoperative characteristics, mortality rate, and postoperative complications were similar between these two groups. All seven patients ≥80 years of age with an American Society of Anesthesiologists (ASA) score of 2 survived after surgery. All five patients with a Mannheim peritonitis index (MPI) score of ≥26 in the elderly group died after surgery. There were significant associations between the mortality, the MPI and ASA score in patients ≥80 years of age. CONCLUSIONS Best supportive care may be an alternative for patients ≥80 years of age with PD, an ASA score of ≥3 or an MPI score of ≥26.

Abstract
Colonic diverticular disease is common in Western countries and its prevalence increases with age. The large majority of patients (80-85%) will remain entirely asymptomatic throughout their life. In symptomatic cases, most patients will have diverticulosis without inflammation while the remainder will have diverticulitis with or without complications. About 1-2% will require hospitalization and 0.5% will require surgery. Factors predicting the development of symptoms remain to be identified. However, it is generally recognized that diverticular disease is probably related to complex interactions between colon structure, intestinal motility, diet, and genetic features. Epidemiologic studies have demonstrated an association between diverticulosis and diets that are low in fiber and high in refined carbohydrates. Although the causes of symptom development are still unclear, it is thought that previous episodes of intestinal inflammation may play a role. Changes in intestinal microflora could be one of the putative mechanisms responsible for low-grade inflammation. In patients with uncomplicated diverticulosis, a diet abundant in fruit and vegetables is recommended. The current therapeutic approaches in preventing recurrence of symptoms are based on nonabsorbable antibiotics, mesalazine, and/or probiotics. Cyclic rifaximin administration seems to be an adequate approach to relieving symptoms and preventing acute diverticulitis in patients with symptomatic diverticulosis.

Abstract
AIM: To compare the natural history and course of acute diverticulitis in a younger age group with an older population and to evaluate whether younger patients should be managed differently.
METHODS: This study was a retrospective review of 157 patients treated with acute diverticulitis between January 1, 2004 and December 31, 2007. Diverticulitis was stratified according to the Hinchey classification. Patients were divided into 2 populations: group A ≤ 50 years (n = 31); group B > 50 years (n = 126). Mean patient follow-up was 15 mo.
RESULTS: The median age was 60 years. A significantly higher proportion of patients in group B presented with complicated diverticulitis (36.5% vs 12.9%, P = 0.01). Recurrence was more frequent in group A (25.8% vs 11.1%, P = 0.03) and the mean time-to-recurrence was shorter (12 mo vs 28 mo, P = 0.26). The most severe recurrent episodes of acute diverticulitis were classified as Hinchey stage I and none of the patients required emergency surgery. In multivariate analysis, only age (P = 0.024) was identified as an independent prognostic factor for recurrence.
CONCLUSION: Based on the results of this study, the authors recommend that diverticulitis management should be based on the severity of the disease and not on the age of the patient.

Abstract
Rifaximin is a rifamycin derivative that acts by inhibiting bacterial RNA synthesis. Since it is virtually unabsorbed after oral administration, its bioavailability within the GI tract is high, with intraluminal and fecal drug concentrations largely exceeding the minimum inhibitory concentration values observed in vitro against a broad spectrum of bacteria, including Gram-positive and Gram-negative bacteria, both aerobes and anaerobes. The GI tract, therefore, represents the primary therapeutic target and the disorders in which intestinal bacteria have a pathogenic role represent the main indication. This is the case with colonic diverticular disease. As a consequence, the broad antibacterial activity of rifaximin appears to be of value in the treatment of this clinical condition. Clinical trials have provided evidence of the substantial benefit of rifaximin in diverticular disease. Indeed, available data show the efficacy of the drug in achieving symptomatic relief in patients with uncomplicated disease. A therapeutic gain of approximately 30%, compared with fiber supplementation only, can be expected after cyclic administration of rifaximin for 12 months. However, its value in the prevention of inflammatory complications of the disease needs to be further explored. Recent studies have shown some evidence of synergy between rifaximin and mesalazine and suggest that a combined treatment could be worthwhile in selected subsets of patients with diverticular disease.

Abstract
OBJECTIVE The pathogenesis of symptoms of uncomplicated diverticular disease (UDD) is unclear, but changes in gut microflora and physiologic inflammation may be implicated. The objective of the study was to investigate the distribution of gut homing lymphocytes in peripheral blood and intestinal mucosa of UDD patients, and the effects of luminal antibiotic treatment. MATERIAL AND METHODS Ten UDD patients and 10 age- and gender-matched healthy subjects underwent peripheral blood sampling, and colonoscopy with biopsies taken from the transverse and sigmoid colon. Treatment consisted of a 2-month course of rifaximin 1.2 g/day for 15 days/month. Blood sample and mucosal biopsies were repeated in UDD patients at the end of treatment. Flow cytometry was performed using monoclonal antibodies (CD3, CD4, CD8, CD25, CD19, CD45, CD62L, CD103). RESULTS In peripheral blood, both CD4+ and CD8+/CD103+ were significantly higher in patients at baseline than in controls (0.95% versus 0.36%, and 0.5% versus 0.09%, respectively). After treatment, peripheral CD4+/CD103+ decreased (0.27%), while CD8+/CD103+ did not change (0.35%); on the contrary, peripheral CD25+ increased, the CD4+ subpopulation showing significantly higher levels than those in controls. No difference was found between lymphocytes in the diverticular sigmoid mucosa of patients at baseline and those in controls, but there was a significant decrease in CD8+/CD62L+ after treatment. In the normal transverse colon, CD4+/CD62L+ of patient at baseline were significantly lower than in controls. After treatment, CD4+/CD103+ levels significantly increased, while CD8+/CD62L+ levels significantly decreased. CONCLUSIONS Both central and mucosal immunity may be modified in UDD patients, with an increased recruitment of CD103+ lymphocytes. A 2-month course of rifaximin appears to reduce CD103+ levels, suggesting a decrease in mobilization of mucosal homing.

Abstract
AIM Antecedent attacks of diverticulitis are thought to increase the risk of complicated diverticulitis, and unless elective surgery is performed, a high proportion of patients with recurrent symptoms will require emergency operations for complicated diverticulitis with its associated morbidity. In this multicentre study, we aim to assess impact of previous attacks of diverticulitis on patients requiring an emergency surgical intervention. METHOD All patients operated on as an emergency for complicated diverticulitis were retrospectively analysed. Patients were separated into two groups: group A included patients without previous history of diverticular disease, and group B those with previous attacks of diverticulitis. RESULTS A total of 96 patients were included in the study. Group A included 68 (70.8%) patients, and group B 28 (29.2%) patients. Generalized peritonitis was the reason for operation in 50 (73.5%) patients in-group A and only four (14%) patients in group B. Perforated diverticulitis occurred more often in group A, whereas pericolonic abscess and phlegmon formation occurred more commonly in group B. Resection was performed in all patients in group B; 50% had a Hartmann's procedure, and the other 50% patients had primary anastomosis. Hartmann's procedure was performed in 52 patients (76.5%) in group A, and 8 patients (11.7%) had resection and primary anastomosis. No difference in postoperative complications was identified between the groups. CONCLUSION Multiple attacks of diverticulitis are not associated with an increased risk of complicated diverticulitis. Recurrent episodes of diverticulitis are not associated with a less favourable outcome or an increased risk of fatality if complications ensue.

Abstract
The differential diagnosis of abdominal pain should not rank diverticulitis any differently in immunosuppressed transplant or AIDS patients than in other patients of the same sex and age and with the same clinical presentation. Immunocompromised patients have increased postoperative infectious risks in direct proportion to the degree of their immune deficiency.

Abstract
AIM: To identify patients with persistent acute diverticulitis who might benefit from an early colonoscopy during their first hospitalization.
METHODS: All patients hospitalized between July 2000 and December 2006 for acute diverticulitis who underwent colonoscopy were included in the study. Patients were followed during hospitalization and after discharge. Patients were considered to have a persistent course of acute diverticulitis if symptoms continued after 1 wk of conventional treatment with IV antibiotics, or if symptoms recurred within 2 mo after discharge. Patients were considered to benefit from an early colonoscopy if the colonoscopy was therapeutic or if it changed a patient's outcome.
RESULTS: Three hundred and six patients were hospitalized between July 2000 and December 2006 with the diagnosis of acute diverticulitis. Two hundred and twenty four of these were included in the study group. Twenty three patients (10.3%) fulfilled the criteria for a persistent course of acute diverticulitis. Of them, four patients (17.4%) clearly benefited from an early colonoscopy; these patients’ clinical course is described. None of the patients with a regular non-persistent course demonstrated any benefit from colonoscopy.
CONCLUSION: Early colonoscopy detected other significant pathology, which accounted for the clinical presentation in 17% of patients with persistent acute diverticulitis. Therefore, we believe an early colonoscopy should be considered in all patients with a persistent clinical course.

Abstract
Lower gastrointestinal bleeding (LGIB) arises from a number of sources and is a significant cause of hospitalization and mortality in elderly patients. Whereas most episodes of acute LGIB resolve spontaneously with conservative management, an important subset of patients requires further diagnostic workup and therapeutic intervention. Endovascular techniques such as microcatheter embolization are now recognized as safe, effective methods for controlling LGIB that is refractory to endoscopic intervention. In addition, multidetector CT has shown the ability to identify areas of active bleeding in a non-invasive fashion, enabling more focused intervention. Given the relative strengths and weaknesses of various diagnostic and treatment modalities, a close working relationship between interventional radiologists, gastroenterologists and diagnostic radiologists is necessary for the optimal management of LGIB patients.

Abstract
Evaluation of the elderly patient with acute abdominal pain is sometimes difficult. Various factors can obscure the presentation, delaying or preventing the correct diagnosis and leading to adverse patient outcomes. Clinicians must consider multiple diagnoses, especially those life-threatening conditions that require timely intervention to limit morbidity and mortality. This article reviews abdominal pain in the elderly, discusses the clinical approach, and highlights key diagnostic considerations.

Abstract
The current concepts on diagnosis, clinical features, and management of common gastrointestinal conditions in the elderly population, taking into account physiological aspects of ageing, are evaluated. Gastrointestinal (GI) disorders are discussed with an emphasis on oesophageal problems, Helicobacter pylori infection, malabsorption, diverticular disease, and cancer. GI problems are acquiring greater importance in hospitals and in the community and their incidence is increasing. Newer treatments have less impact on patients' wellbeing and meticulously planned investigation and treatment is needed. Careful selection of patients and application of modern techniques has improved survival and outcomes, with comparable results to those in younger age groups.

Abstract
Although diverticular perforation and diverticulitis is usually a straightforward diagnosis, an occasional case can be difficult. In this report, we describe a patient who initially presented with symptoms suggestive of maxillary sinusitis and hip fracture. Findings of subcutaneous craniofacial emphysema eventually led to the diagnosis of a perforated sigmoid diverticulum with abscess.

Abstract
Diverticulitis and appendicitis are common infections of the gastrointestinal tract that require urgent medical and surgical attention. Successful management of these conditions requires a multidisciplinary approach among primary care providers, gastroenterologists, surgeons, and radiologists. The diagnosis of appendicitis, in particular, can be difficult. Advances in radiographic imaging have improved the diagnostic accuracy in these infections. Minimally invasive surgical techniques have improved the patient's postoperative recovery when surgery is necessary in the management of these conditions.

Abstract
Diverticular disease of the colon is the fifth most important gastrointestinal disease in terms of direct and indirect health care costs in western countries. Uncomplicated diverticular disease is defined as the presence of diverticula in the absence of complications such as perforation, fistula, obstruction and/or bleeding. The distribution of diverticula along the colon varies worldwide being almost always left-sided and directly related to age in western countries and right-sided where diet is rich in fibre. The pathophysiology of diverticular disease is complex and relates to abnormal colonic motility, changes in the colonic wall, chronic mucosal low-grade inflammation, imbalance in colonic microflora and visceral hypersensitivity. Moreover, there can be genetic factors involved in the development of colonic diverticula. The use of non-absorbable antibiotics is the mainstay of therapy in patients with mild to moderate symptoms, and the effect of fibre-supplementation alone does not appear to be significantly different from placebo, although no definite data are available. More recently, alternative treatments have been reported. Mesalazine acts as a local mucosal immunomodulator and has been shown to improve symptoms and prevent recurrence of diverticulitis. In addition, probiotics have also been shown to be beneficial by re-establishing a normal gut microflora. In this study, the current literature on uncomplicated diverticular disease of the colon is reviewed.

Abstract
AIM: To prospectively study the incidence and the natural history of acute diverticulitis in young patients.
METHODS: A total of 207 patients hospitalized at our hospital between January 2000 to February 2005 with the diagnosis of acute diverticulitis were included. Their demographic characteristics, medical history, physical, radiographic and endoscopic findings as well as therapy were recorded. Patients were followed every 6 mo for the first year and later annually.
RESULTS: The mean patients’ age was 61 (range 27-92) years. Twenty- five patients (12%) were younger than 45 years. Acute diverticulitis was significantly more prevalent among male in the young age group as compared to the older age group (19/25, 76% vs 61/182, 33%, respectively, P = 0.0001). Complications occurred more often in the young age group; 32% vs 13%, (P = 0.002). During follow-up, 6 patients (28%) remained asymptomatic in the young age group as compared to 87 patients (55%) in the older age group (P = 0.024). As a result, sigmoidectomies were performed twice as often in the young age group (38% vs 13%, P = 0.002).
CONCLUSION: Diverticulitis in young patients has a male predominance, a more aggressive course with a higher rate of complications and a higher recurrence rate. An earlier surgical approach might be considered in young patients with acute diverticulitis.

Abstract
OBJECTIVE Auditing the outcome of surgery for complicated diverticulitis of the sigmoid colon is difficult. A comparison of studies is hardly possible because risk factors both in terms of the severity of diverticulitis and patient-related risk factors are neither well described nor standardized. The purpose of this study was to define morbidity and mortality of primary surgery for acute complications of diverticular disease of the sigmoid colon and to identify the relation between risk factors and morbidity and mortality. METHODS In a prospective computerized morbidity and mortality registration from 1990 to 2002, 114 patients, who underwent surgery on an acute or urgent base for acute complications of diverticular disease of the sigmoid colon, were identified. In all patients the POSSUM score was calculated. To audit mortality rates a POSSUM based scoring system was introduced. RESULTS Mortality was 16.7%, and morbidity 71.1%. Higher morbidity rates were significantly related to a higher POSSUM physiological score (P = 0.012) and to older age (P < 0.001). Higher mortality rates also were significantly related to a higher POSSUM physiological score (P < 0.001) and older age (P = 0.003). Patients who died had significantly more sepsis (P < 0.001), multiple organ failure (P = 0.027), cardiac (P < 0.001) and pulmonary (P = 0.013) complications. Gender, operation indication and type of neither surgery nor surgeon had a significant relation with morbidity or mortality. CONCLUSION Surgery for acute complications of diverticular disease of the sigmoid colon carries a high morbidity rate and a substantial mortality rate. The majority of deceased patients had severe comorbidity. Post-operative mortality and morbidity are to a large extent driven by patient related factors. Elevated physiological severity scores and a lack of peri-operative management failures express this in the majority of deceased patients.

Abstract
Treatment of symptomatic diverticular disease of the colon is aimed at the relief of symptoms and the prevention of major complications. The efficacy of fiber supplementation and of anticholinergic and spasmolytic agents remains controversial. Antibiotics are commonly used in the treatment of inflammatory complications of diverticular disease. Data from open labelled and randomized controlled trials do suggest the efficacy of rifaximin in obtaining symptomatic relief in patients with diverticular disease. Approximately 30% therapeutic gain compared to fiber supplementation only can be expected after one year of intermittent treatment with rifaximin. Considering the safety and tolerability of rifaximin, this drug can be recommended for patients with symptomatic uncomplicated diverticular disease.

Abstract
PURPOSE Acute diverticulitis is a disease with a wide clinical spectrum, ranging from a phlegmon (stage Ia), to localized abscesses (stages Ib and II), to free perforation with purulent (stage III) or feculent peritonitis (stage IV). While there is little debate about the best treatment for mild episodes and/or very severe episodes, uncertainty persists about the optimal management for intermediate stages (Ib and II). The aim of our study was therefore to define the role of computed tomography (CT) and to analyze its impact on the management of acute diverticulitis. METHODS We retrospectively analyzed 511 patients (296 males, 215 females) admitted for acute diverticulitis between January 1994 and December 2003. Excluded were patients with stoma reversal only, "diverticulitis" mimicked by cancer, or significantly deficient patient records. Patients were analyzed either as a whole or subgrouped according to age (<40 yr, >40 yr). A modified Hinchey classification was used to stage the severity of acute diverticulitis. RESULTS In 99 patients (19.4%), an abscess was found (74 pericolic, 25 pelvic, median diameter: 4.0 cm). CT-guided drainage was performed in 16 patients, one failure requiring a two-stage operation. Whereas conservative treatment failed in 6.8% in patients without abscess or perforation, 22.2% of patients with an abscess required an urgent resection (68.2%, one-stage, 31.8%, two-stage). Recurrence rates were 13% for mild cases, as compared to 41.2% in patients with a pelvic abscess (stage II) treated conservatively with/without CT-guided drainage. Of all surgical cases, resection/primary anastomosis was achieved in 73.6% with perioperative mortality of 1.1% and leak rate was 2.1%. CONCLUSIONS CT evidence of a diverticular abscess has a prognostic impact as it correlates with a high risk of failure from nonoperative management regardless of the patient's age. After treatment of diverticulitis with CT evidence of an abscess, physicians should strongly consider elective surgery in order to prevent recurrent diverticulitis.

Abstract
PURPOSE The aim of of this study was to evaluate prospectively the long-term outcome of mesocolic and pelvic diverticular abscesses of the left colon. METHODS Between October 1986 and October 1997, a total of 465 patients urgently admitted to our hospital with a suspected diagnosis of acute left-sided colonic diverticulitis had a CT scan. Of 76 patients (17 percent) who had an associated mesocolic or pelvic abscess, 3 were lost to follow-up. The remaining 73 patients (45 with a mesocolic abscess and 28 with a pelvic abscess) were followed for a median of 43 months. RESULTS of the 45 patients with a mesocolic abscess, 7 (15 percent) required surgery during their first hospitalization versus 11 (39 percent) of the 28 patients with a pelvic abscess (P = 0.04). At the end of follow-up, 22 (58 percent) of the 38 patients with a mesocolic abscess who had successful conservative treatment during their first hospitalization did not need surgical treatment vs. 8 (47 percent) of the 17 who had a pelvic abscess. Altogether, 51 percent of the patients with a mesocolic abscess had surgical treatment versus 71 percent of those with a pelvic abscess (P = 0.09). CONCLUSIONS Considering the poor outcome of pelvic abscess associated with acute left-sided colonic diverticulitis, percutaneous drainage followed by secondary colectomy seems justified. Mesocolic abscess by itself is not an absolute indication for colectomy.

Abstract
BACKGROUND AND AIMS MRI-based colonography is a new minimally invasive imaging modality to assess the colon and abdomen. This new method which is applied mainly for polyp screening could be an integrative approach for colonic diverticulitis assessment. This study evaluated the feasibility of MRI-based colonography to assess diverticulosis or diverticulitis. PATIENTS AND METHODS Fourteen consecutive patients with clinically suspected diverticulitis were examined by MRI colonography on a 1.5-T scanner. All patients underwent abdominal CT as gold standard. N-Butyl-scopalamin was given intravenously to reduce bowel peristalsis. After rectal administration of a T1-positive enema T1- and T2-weighted acquisitions with additional intravenous contrast were obtained. A 3D FLASH sequence was acquired for virtual colonography. The results were compared with CT and biological parameters such as white blood cell count and C-reactive protein. RESULTS Of 56 bowel segments (sigmoid colon, descending colon, transverse colon, ascending colon) in all 14 patients 54 were assessed to have good to fair image quality. Having CT as standard of reference, all sigmoid diverticula were diagnosed based on MRI. Inflammation as judged by CT was identically assessed on MRI. 3D models of the colon revealed further diverticula in the remaining colon; additionally, the 3D models gave a comprehensive image for surgical planning. CONCLUSION In our preliminary study MRI colonography revealed the same diagnosis as CT in all patients without ionizing radiation. Additionally, 3D-rendered models and virtual colonoscopy can be performed. This comprehensive 3D models could replace presurgical planning barium enema with concurrent assessment of the residual colon.

BACKGROUND Colonic diverticular disease is more common in Western populations than in developing countries. AIM To determine whether the frequency of colonic diverticular disease is different in British patients of Indian-subcontinent Asian origin compared with other ethnic groups. METHODS All colonoscopies performed over a 3-year period in a London hospital were studied. Patients of Indian-subcontinent Asian origin were identified by name. RESULTS Five of 134 Indian-subcontinent Asian males (4%) had colonic diverticular disease, compared with 278 of 1268 patients of other ethnic groups (22%; P < 0.001). Five of 91 Indian-subcontinent Asian females (6%) had colonic diverticular disease, compared with 333 of 1486 patients of other ethnic groups (23%; P < 0.001). Although patients of Indian-subcontinent Asian origin (54.8 +/- 15.8 years) were younger than those of other ethnic groups (60.3 +/- 17.8 years; P < 0.0001), the ethnic difference in the frequency of diverticular disease persisted even when age was taken into account. CONCLUSION There is a lower frequency of colonic diverticular disease in Indian-subcontinent Asians presenting for colonoscopy, compared with other ethnic groups. This cannot be explained by sex or age differences. Our findings require confirmation, but may provide opportunities for research into the aetiology of colonic diverticular disease.

Abstract
Diverticulosis and diverticulitis are common disorders in modern society and represent different places on the spectrum of diverticular disease. Often called a problem of western civilization, diverticular disease is rare in developing countries. This article provides an overview of the epidemiology of diverticular disease, risk factors, and clinical presentation in varying phases. Differential diagnostic testing and comprehensive management from the medical, surgical, and wound, ostomy, and continence nursing perspectives are also addressed. Nurses play a key role in supporting people with diverticular disease and referring them for appropriate assessment, treatment, and support.

Abstract
Diverticular disease of the colon is a common disease worldwide. Although the disease is asymptomatic in about 70%-80% of patients, it represents, at least in Western countries, one of the most important gastrointestinal diseases in terms of direct and indirect health costs. Pathogenesis of the disease is still unknown. However, it is the result of complex interactions between colonic structure, intestinal motility, diet and genetic factors. Whilst efficacious preventive strategies remain to be identified, fibre supplementation in the diet is recommended. Why symptoms develop is still unclear. Results of recent experimental studies on irritable bowel syndrome speculated that low grade inflammation of colonic mucosa, induced by changes in bacterial microflora, could affect the enteric nervous system, which is crucial for normal gut function, thus favouring symptom development. This hypothesis could be extrapolated also for diverticular disease, since bacterial overgrowth is present, at least in a subgroup of patients. These perspectives on symptom development are reviewed and new therapeutic approaches are hypothesized.

Abstract
Flexible sigmoidoscopy and colonoscopy have revolutionized the clinical management of colonic diseases. Colonoscopy is a highly sensitive and specific test. Colonic diseases often produce characteristic colonoscopic findings, as well as characteristic histologic findings, as identified in colonoscopic biopsy or polypectomy specimens. Colonoscopy is relatively safe, with a low incidence of serious complications, such as colonic perforation, hemorrhage, cardiopulmonary arrest, or sepsis. Colonoscopy is becoming more important clinically because of more widespread use of screening colonoscopy for colon cancer, application of therapeutic colonoscopy, and exciting new technical improvements.

Abstract
Colonic diverticula are protrusions of the mucosa through the outer muscular layers, which are usually abnormally thickened, to form narrow necked pouches. Diverticular disease of the colon covers a wide clinical spectrum: from an incidental finding to symptomatic uncomplicated disease to diverticulitis. A quarter of patients with diverticulitis will develop potentially life-threatening complications including perforation, fistulae, obstruction or stricture. In Western countries diverticular disease predominantly affects the left colon, its prevalence increases with age and its causation has been linked to a low dietary fibre intake. Right-sided diverticular disease is more commonly seen in Asian populations and affects younger patients. Its pathogenesis and relationship to left-sided diverticular disease remains unclear. Diverticular disease of the colon is a significant cause of morbidity and mortality in the Western world and its frequency has increased throughout the whole of the 20th century. Since it is a disease of the elderly, and with an aging population, it can be expected to occupy an increasing portion of the surgical and gastroenterological workload. It is uncertain what symptoms uncomplicated diverticular disease gives rise to: there is an overlap with irritable bowel syndrome. Diagnosis is primarily by barium enema and colonoscopy, but more sophisticated imaging procedures such as computed tomography (CT) are increasingly being used to assess and treat complications such as abscess or fistula, or to provide alternative diagnoses if diverticulosis is not confirmed. Initial therapy for uncomplicated diverticulitis is supportive, including monitoring, bowel rest and antibacterials. CT is used to guide percutaneous drainage of abscesses to avoid surgery or allow it to be performed as an elective procedure. Surgery is indicated for complications of acute diverticulitis, including failure of medical treatment, gross perforation, and abscess formation that cannot be resolved by percutaneous drainage. Complications of chronic diverticulitis (fistula formation, stricture and obstruction) are also usually treated surgically. However, the indications for, and the timing and staging of operations for diverticular disease are often difficult decisions requiring sound clinical judgement. Factors such as the number of episodes of inflammation, the age of the patient, and his/her overall medical condition play a role in determining whether or not a patient should undergo surgical resection. Laparoscopic surgery may be associated with less pain, less morbidity and shorter hospital stays, but its exact role is yet to be defined. Diverticular disease of the colon is the most common cause of acute lower gastrointestinal haemorrhage, which can be massive. Although the majority of patients stop bleeding spontaneously, angiographic and surgical treatment may be required, while the place of endoscopic haemostasis remains to be established.
