Comparative outcomes of acute colonic diverticulitis in immunocompromised versus immunocompetent patients: a systematic review and meta-analysis. Intest Res 2023; 21:481-492. [PMID: 37248174 PMCID: PMC10626017 DOI: 10.5217/ir.2023.00005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Revised: 02/22/2023] [Accepted: 03/31/2023] [Indexed: 05/31/2023] Open
Abstract
BACKGROUND/AIMS Immunocompromised patients with acute colonic diverticulitis are at high risk for complications and failure of non-surgical treatment. However, evidence on the comparative outcomes of immunocompromised and immunocompetent patients with diverticulitis is lacking. This systematic review and meta-analysis investigated the outcomes of medical treatment in immunocompromised and immunocompetent patients with diverticulitis. METHODS A comprehensive literature search was conducted in PubMed, Embase, and the Cochrane Library. Studies comparing the clinical outcomes of immunocompromised and immunocompetent patients with diverticulitis were included. RESULTS A total of 10 studies with 1,946,461 subjects were included in the quantitative synthesis. The risk of emergency surgery and postoperative mortality after emergency surgery was significantly higher in immunocompromised patients than in immunocompetent patients with diverticulitis (risk ratio [RR], 1.76; 95% confidence interval [CI], 1.31-2.38 and RR, 3.05; 95% CI, 1.70-5.45, respectively). Overall risk of complications associated with diverticulitis was non-significantly higher in immunocompromised than in immunocompetent patients (RR, 1.24; 95% CI, 0.95-1.63). Overall mortality irrespective of surgery was significantly higher in immunocompromised than in immunocompetent patients with diverticulitis (RR, 3.65; 95% CI, 1.73-7.69). By contrast, postoperative mortality after elective surgery was not significantly different between immunocompromised and immunocompetent patients with diverticulitis. In subgroup analysis, the risk of emergency surgery and recurrence was significantly higher in immunocompromised patients with complicated diverticulitis, whereas no significant difference was shown in mild disease. CONCLUSIONS Immunocompromised patients with diverticulitis should be given the best medical treatment with multidisciplinary approach because they had increased risks of surgery, postoperative morbidity, and mortality than immunocompetent patients.

Abstract
BACKGROUND/AIMS Some management strategies for acute colonic diverticulitis remain controversial in Korean real-world practice because their clinical features differ from those in the West. This study aimed to investigate the opinions of Korean physicians regarding the diagnosis and treatment of acute diverticulitis. METHODS A web-based survey was conducted among gastroenterologists specializing on treating lower gastrointestinal disorders. The questionnaires concerned overall management strategies for colonic diverticulitis, including diagnosis, treatment, and follow-up. RESULTS In total, 209 gastroenterologists responded to the survey. Less than one-fourth of the respondents (23.6%) answered that left-sided colonic diverticulitis is more likely to be complicated than right-sided colonic diverticulitis. Most respondents agreed that immunocompromised patients with diverticulitis have worse clinical outcomes than immunocompetent patients (71.3%). Computed tomography was the most preferred tool for diagnosing diverticulitis (93.9%). Approximately 89% of the respondents answered that they believed antibiotic treatment is necessary to treat acute uncomplicated diverticulitis. Most respondents (92.6%) agreed that emergency surgery is not required for diverticulitis with an abscess or microperforation without panperitonitis. Further, 94.7% of the respondents agreed that colon cancer screening is necessary in patients aged ≥ 50 years with diverticulitis after they have recovered from acute illness. Many respondents (71.4%) agreed that surgery for recurrent diverticulitis should be individualized. CONCLUSION Opinions regarding management strategies for colonic diverticulitis among Korean gastroenterologists were well agreed upon in some areas but did not agree well in other areas. Evidence-based guidelines that meet the practical needs of the Korean population should be developed.

Abstract
BACKGROUND AND OBJECTIVE Colorectal cancer (CRC) can mimic acute diverticulitis and can thus be misdiagnosed. Therefore, colonic evaluation is recommended after an episode of acute diverticulitis. The aim of this study was to analyze the risk of CRC after computed tomography (CT) verified uncomplicated and complicated acute diverticulitis in short-term and, particularly, long-term follow-up to ensure the feasibility of the primary CT imaging in separating patients with uncomplicated and complicated acute diverticulitis. METHODS A retrospective cohort study was conducted in patients with CT-verified acute diverticulitis in 2003-2012. Data on CT findings and colonic evaluations were analyzed. The patients were divided into those with uncomplicated and complicated acute diverticulitis. Patient charts were reviewed 9-18 years after the initial acute diverticulitis episode. RESULTS The study population consisted of 270 patients. According to CT scans, 170 (63%) patients had uncomplicated acute diverticulitis and 100 (37%) had complicated acute diverticulitis. Further colonic evaluation was made in 146 (54%) patients. In the whole study population, CRC was found in 7 (2.6%) patients, but CRC was associated with acute diverticulitis in only 4 (1.5%) patients. The short-term risk for CRC was 0.6% (1/170) in uncomplicated acute diverticulitis and 3.0% (3/100) in complicated acute diverticulitis. No additional CRC was found in patients with complicated acute diverticulitis during the long-term follow-up and three cases of CRC found after uncomplicated acute diverticulitis had no observable association with previous diverticulitis. CONCLUSIONS In short-term follow-up, the risk of underlying CRC is very low in CT-verified uncomplicated acute diverticulitis but increased in complicated acute diverticulitis. Long-term follow-up revealed no additional CRCs associated with previous acute diverticulitis, indicating that the short-term results remain consistent also in the long run. These long-term results confirm that colonoscopy should be reserved for patients with complicated acute diverticulitis or with persisting or alarming symptoms.

Abstract
Background: It is recognized increasingly that common surgical infections of the peritoneal cavity may be treated with antibiotic agents alone, or source control surgery with short-course antimicrobial therapy. By extension, testable hypotheses have emerged that such infections may not actually be infectious diseases, but rather represent inflammation that can be treated successfully with neither surgery nor antibiotic agents. The aim of this review is to examine extant data to determine which of uncomplicated acute appendicitis (uAA), uncomplicated acute calculous cholecystitis (uACC), or uncomplicated mild acute diverticulitis (umAD) might be amenable to management using supportive therapy alone, consistent with the principles of antimicrobial stewardship. Methods: Review of pertinent English-language literature and expert opinion. Results: Only two small trials have examined whether uAA can be managed with observation and supportive therapy alone, one of which is underpowered and was stopped prematurely because of challenging patient recruitment. Data are insufficient to determine the safety and efficacy of non-antibiotic therapy of uAA. Uncomplicated acute calculous cholecystitis is not primarily an infectious disease; infection is a secondary phenomenon. Even when bactibilia is present, there is no high-quality evidence to suggest that mild disease should be treated with antibiotic agents. There is evidence to indicate that antibiotic prophylaxis is indicated for urgent/emergency cholecystectomy for uACC, but not in the post-operative period. Uncomplicated mild acute diverticulitis, generally Hinchey 1a or 1b in current nomenclature, does not benefit from antimicrobial agents based on multiple clinical studies. The implication is that umAD is inflammatory and not an infectious disease. Non-antimicrobial management is reasonable. Conclusions: Among the considered disease entities, the evidence is strongest that umAD is not an infectious disease and can be treated without antibiotic agents, intermediate regarding uACC, and lacking for uAA. A plausible hypothesis is that these inflammatory conditions are related to disruption of the normal microbiome, resulting in dysbiosis, which is defined as an imbalance of the natural microflora, especially of the gut, that is believed to contribute to a range of conditions of ill health. As for restorative pre- or probiotic therapy to reconstitute the microbiome, no recommendation can be made in terms of treatment, but it is not recommended for prevention of primary or recurrent disease.

Abstract
PURPOSE The aim of this review was to examine if diverticulitis increases the long-term risk (> 6 months) of developing colon cancer. METHODS A systematic search was conducted in PubMed, Embase, and Cochrane CENTRAL. Google Scholar was also searched. We included studies with human adults of 18 years of age and above. Studies that included only patients with diverticulitis as well as studies comparing groups with and without diverticulitis were included. The primary outcome was the incidence of colon cancer 6 months or more after an episode of diverticulitis. RESULTS Twelve records were included with 38,621 patients with diverticulitis. The crude rate of colon cancer among the prospectively followed populations with diverticulitis was by meta-analysis found to be 0.6% (95% CI 0.5-0.6%). The limitations of this review include heterogeneous reporting of outcomes across studies, specifically regarding population and outcome as well as variations in the design and reporting of the studies. CONCLUSION We found that the long-term risk of colon cancer after diverticulitis is not increased. The results of our review support current practice on follow-up after an episode of diverticulitis with short-term follow-up being the primary focus.

Abstract
Colonic diverticulosis is one of the most common conditions of the digestive system and patients generally remain asymptomatic. However, about 20% of patients develop symptomatic diverticular disease such as acute diverticulitis or diverticular hemorrhage, and these have become a huge burden on healthcare systems worldwide. Recent understanding of the pathophysiology of diverticulosis and diverticular disease suggests the role of multiple factors including genetic and environment. Based on this understanding, a preventive strategy to reduce the risk factors of diverticulosis and diverticular disease is highly recommended. The diagnosis of the acute diverticulitis relies on imaging modalities such as an abdominal-pelvic CT scan together with symptoms and signs. Treatment of diverticular disease should be individualized and include modification of lifestyle, use of antibiotics, and surgery. Recent guidelines recommend pursuing less aggressive treatment for patients with acute diverticulitis. This review will provide an overview of both the existing and evolving understanding regarding colonic diverticulosis and diverticular disease and can help clinicians in the management of their patients with diverticular disease.

Abstract
BACKGROUND Due to variable rates of colon carcinoma or advanced adenoma mimicking an acute diverticulitis episode, the necessity of colonoscopy to detect colon cancer or advanced adenoma remains to be explored. This study investigated the incidence and predictive factors of colon cancer or advanced adenoma following acute diverticulitis. METHODS We evaluated retrospectively all consecutive patients with an episode of computed tomography-proven acute diverticulitis between June 2016 and August 2019. A follow-up colonoscopy was performed. Demographic and clinical parameters were recorded. Patients with clinically substantial colonic neoplasia (colon cancer or advanced adenoma) were classified as Group A, while Group B included patients without clinically significant colonic neoplasia. The incidence of clinically significant colonic neoplasia in acute diverticulitis patients was regarded as the primary outcome. RESULTS The mean age of 233 patients with acute diverticulitis was 58.6 ± 12.7 years. Complicated diverticulitis was detected in 39 patients (16.7 %). Sixteen patients (6.9 %) were assigned to Group A and 217 patients (93.1 %) to Group B. The age of the patients in group A was significantly higher than in Group B (p =0.001). Age above 50 and 65 years was also significantly associated with clinically significant colonic neoplasia (p =0.015 and p =0.012, respectively). The other variables did not influence the development of clinically significant colonic neoplasia (p >0.05). CONCLUSIONS Colonoscopy examination following an episode of acute diverticulitis may not be recommended for all patients due to the rare occurrence of colon cancer or clinically significant colonic neoplasia in those younger than 50 years. HIPPOKRATIA 2021, 25 (2):69-74.

Abstract
Recent reports have documented an unchanged rate of occurrence of colorectal cancer (CRC) and have publicised doubts regarding the benefit of prompt colonoscopy procedures after an episode of acute diverticulitis (AD). These reports mandate further evaluation of colonoscopy yield and timing in this regard. The current study aims to determine whether the rate of advanced colonic neoplasia after AD differs from that of average-risk patients, and to identify risk factors that are associated with their development.In this retrospective study, we included all patients who had been hospitalized to the surgery ward in the years 2008 to 2016 with radiographically confirmed AD, and had completed colonoscopies within one year of index hospitalization. Patients who were referred for screening colonoscopies during the same years were included as a control group. We compared the rates of diagnosis of CRC and advanced polyps for both groups before and after adjustment for multiple confounders. Moreover, we investigated risk factors that were associated with increased rate of advanced neoplasia diagnosis.A total of 350 patients were included in the AD group and 1502 patients in the screening colonoscopy control group. The CRC diagnosis rates (1.7% vs 0.3%; P = .09) and overall diagnosis rates of advanced neoplasia (12.3% vs 9.6%; P = .19) were not significantly different when findings were compared between the AD and control groups, respectively. Cases of complicated diverticulitis, however, were associated with increased risk of advanced neoplasia diagnosis (odds ratio (OR) 3.729, 95% confidence interval (CI) 1.803-7.713; P = .01).The diagnosis rate for advanced neoplasia after AD was not significantly different from that of average-risk populations. A course of complicated AD, however, was a potential risk factor.

Abstract
BACKGROUND CT findings of acute diverticulitis can overlap with features of malignancy, and current guidelines recommend colonic evaluation after acute diverticulitis. However, the benefits of routine colonic evaluation have been questioned. OBJECTIVE We review 30 studies, composed of 29,348 subjects, to evaluate the role of routine colonic evaluation after CT-proven acute diverticulitis. DATA SOURCES Medline, EMBASE, and the Cochrane Library were searched for articles published up to July 2018 to identify all relevant articles. STUDY SELECTION A combination of both Medical Subject Headings and non-Medical Subject Headings key terms using Boolean operators were used on Medline, including colonic neoplasms, colorectal cancer, colon cancer, colonic cancer, colonoscopy, and diverticulitis. Any randomized or nonrandomized, English-language article that specifically analyzed incidence of colorectal cancer after performing colonoscopy in patients with previous diverticulitis was included. MAIN OUTCOME MEASURES The desired outcome was to evaluate for incidence of colonic malignancy in cases of acute colonic diverticulitis. Subgroup analyses for incidence of malignancy in uncomplicated and complicated diverticulitis, and Asian population studies were also performed. RESULTS Findings of colonic malignancy occurred in 1.67% (95% CI, 1.24-2.14) of patients with CT-diagnosed diverticulitis. The risk of malignancy in cases with uncomplicated diverticulitis was 1.22% (95% CI, 0.63-1.97) as compared with 6.14% (95% CI, 3.20-9.82) in cases with complicated diverticulitis, with a relative risk of 5.033 (95% CI, 3.194-7.930; p < 0.001). LIMITATIONS Significant variability in design and methodology of the individual studies contributed to the heterogeneity of this study, but these were addressed by using the random-effects model analysis. CONCLUSIONS Colonic evaluation is worth considering for patients with diverticulitis because of the small but serious risk of underlying malignancy. The risk of malignancy is higher for patients of advanced age and with complicated diverticulitis.

Abstract
Background Diverticular disease of the colon has a high global prevalence. The guidelines suggest performing a colonoscopy 4-6 weeks after the acute episode to exclude colorectal cancer (CRC). However, these recommendations are based on old studies, when computed tomography was not used to diagnose acute diverticulitis (AD). There are currently some studies showing that CRC incidence is low in uncomplicated AD (UAD). Therefore, we decided to perform this study to determine the CRC incidence after an AD episode and the diagnostic efficacy of colonoscopy in these patients. Method This was a retrospective cohort study that included patients with AD between July 2016 and December 2017. Results One hundred seventy-four patients had AD. Of these, 46 patients were excluded and we analyzed 128 patients, 72 (56.3%) women and 56 (43.7%) men. Ninety (70.3%) had UAD and 38 (29.7%) complicated AD (CAD). The colonoscopy showed lesions in 18 (14.06%), 5 (3.9%) being CRC. The patients with CRC had shown CAD and were >70 years old (P=0.0001 and P=0.002 respectively). Conclusions Routine colonoscopy in patients with UAD appears not have many benefits as a diagnostic tool. However, it has a higher efficacy if the patients have CAD and are >70 years old.

Abstract
Introduction Acute diverticulitis is defined as a macroscopic inflammation of a diverticulum or diverticula. Approximately, 4.0% of patients with diverticulosis present with an acute diverticulitis event: with the incidence increasing in the younger patient population. According to the American Gastrointestinal Association, a colonoscopy should be performed six to eight weeks after resolution of acute diverticulitis. The purpose of this study is to determine if there is malignancy after an acute diverticulitis event in adults less than 50 years old. Methods A retrospective chart review study was performed at Loyola MacNeal Hospital in Berwyn, Illinois. Patients between the ages of 18 and49 years with acute diverticulitis were identified. Of the identified patients, those who underwent colonoscopy after a computed tomography (CT)-verified acute diverticulitis event were recorded. Colonoscopy findings, as well as pathology results, were recorded. Results A total of 295 patient presented with diverticulitis. Of these 295 patients, 111 patients underwent colonoscopy post diverticulitis event. Of the 111 patients, 86 were after uncomplicated event and 25 were after a complicated diverticulitis event. Pre-malignant tubular adenomas were found in 12.8% (11/86) of patients with acute uncomplicated diverticulitis and 24.0% (6/25) of the patients with complicated diverticulitis. No cases of neoplasm were found. Conclusion Of the 111 patients who underwent colonoscopy after an acute diverticulitis event, no malignancy was found in patients less than 50 years of age.

Risk of Colorectal Cancer in Patients With Acute Diverticulitis: A Systematic Review and Meta-analysis of Observational Studies. Clin Gastroenterol Hepatol 2019; 17:1448-1456.e17. [PMID: 30056181 DOI: 10.1016/j.cgh.2018.07.031] [Citation(s) in RCA: 46] [Impact Index Per Article: 9.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/28/2018] [Revised: 07/19/2018] [Accepted: 07/20/2018] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS We performed a systematic review and meta-analysis to assess the prevalence of colorectal cancer in patients with acute diverticulitis. METHODS We searched MEDLINE from inception through November 2nd, 2017 for studies reporting the prevalence of colorectal cancer in patients with diverticulitis, identified based on the protocol CRD42017083272. This systematic review was conducted in accordance to the MOOSE guidelines. Pooled prevalence values were obtained by random effects models and robustness was tested by leave-one out sensitivity analyses. Heterogeneity was assessed using the Q-test and quantified based on I2 value. The critical appraisal of included studies was performed using the Newcastle-Ottawa scale. RESULTS Our final analysis included 31 studies, comprising 50,445 patients. The pooled prevalence of colorectal cancer was 1.9% (95% CI, 1.5%-2.3%). Patients with complicated diverticulitis had a significantly higher risk for colorectal cancer (prevalence, 7.9%; 95% CI, 3.9%-15.3%) than patients with uncomplicated diverticulitis (prevalence, 1.3%; 95% CI, 0.1%-2%), corresponding to a pooled prevalence ratio of 6.7 (95% CI, 2.5-18.3). Subgroup analyses did not find significant difference in prevalence when separately pooling studies according to ranking on the Newcastle-Ottawa scale, geographical location or length of follow-up. Meta-regression did not find any association between age and colorectal cancer. Among patients who underwent endoscopy, the pooled prevalence of polyps was 22.7% (95% CI, 19.6%-26.0%), of advanced adenomas was 4.4% (95% CI, 3.4%-5.8%), of adenomas was 14.2% (95% CI, 11.7%-17.1%), and of hyperplastic polyps was 9.2% (95% CI, 7.6%-11.2%). CONCLUSION In a meta-analysis of observational studies of patients with acute diverticulitis, we found the pooled prevalence of colorectal cancer to be 1.9%. The risk of colorectal cancer was significantly higher in patients with complicated diverticulitis than in patients with uncomplicated diverticulitis.

Abstract
INTRODUCTION Patients treated conservatively for acute diverticulitis (AD) are recommended colonic assessment to rule out an underlying Colorectal cancer (CRC). This has been questioned in patients with a CT diagnosis of uncomplicated AD. We analyzed the frequency of CRC and compared the characteristics of the CRC patients with controls. METHOD A cohort of patients treated conservatively for AD during 2005-2011 was identified through an administrative database. Patients diagnosed with CRC within 1 year after the index admission and four randomly selected controls were identified. The patients' files were reviewed to verify the diagnosis and obtain information about the clinical characteristics and the management. A blinded review was performed of CT examinations. The expected number of CRC was calculated from age, sex, and period-specific incidence data. The characteristics of the CRC patients were compared with the controls in a nested case-control study. RESULTS 890 patients (298 men and 592 women) were treated conservatively for AD. 12 patients were diagnosed with CRC within 1 year, and ten of them in the sigmoid, giving a Standardized Incidence Ratio of 20.0 (95 % CI 10.2-35.7, p<0.001) for sigmoidal cancer. All CRC patients were aged over 70 years. The cancer was missed in six CT scans at the primary reading and in five at the blinded review. CONCLUSION Patients conservatively treated for AD are at high risk for an underlying CRC, especially if older than 70 years, which motivates routine follow-up. A CT diagnosis of uncomplicated AD does not rule out CRC.

Abstract
Acute diverticulitis of the colon is a common indication for computed tomography,
and its diagnosis and complications are essential to determining the proper
treatment and establishing the prognosis. The adaptation of the surgical
classification for computed tomography has allowed the extent of intestinal
inflammation to be established, the computed tomography findings correlating
with the indication for treatment. In addition, computed tomography has proven
able to distinguish among the main differential diagnoses of diverticulitis.
This pictorial essay aims to present the computed tomography technique, main
radiological signs, major complications, and differential diagnoses, as well as
to review the classification of acute diverticulitis.

Colonoscopy after Hinchey I and II left-sided diverticulitis: utility or futility? Am J Surg 2016; 212:837-843. [PMID: 27287835 DOI: 10.1016/j.amjsurg.2016.02.012] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2015] [Revised: 01/26/2016] [Accepted: 02/09/2016] [Indexed: 12/16/2022]
Abstract
BACKGROUND Modern 64- to 128-slice computed tomography (CT) scanners have questioned the need for routine colonoscopy after hospital admission for presumed uncomplicated diverticulitis. METHODS This is a retrospective review of all patients (>18 years) who underwent planned colonoscopy after admission for Hinchey I or II acute diverticulitis (January 2009 to January 2014). The findings on the final radiologist report were then correlated with the colonoscopy results. RESULTS In total, 110 patients (mean age, 55.2 ± 16; 46.4% female) underwent a subsequent colonoscopy (median, 60 days) after admission for diverticulitis. Overall, 102 patients (92.7%) had CT findings consistent with definitive diverticulitis, 6 patients had a diagnosis suggestive of diverticulitis on CT scan, and 2 patients had masses on their admission CT scans. Within the group with definitive diverticulitis, follow-up colonoscopy identified diverticulosis in 99 (97.0%), whereas the other 3 had normal findings. Of the patients with CT scans suggestive of diverticulitis, follow-up colonoscopy showed 3 with diverticulosis, 2 with malignancies, and 1 with nonspecific inflammation. The reliability of CT scans for diverticulitis compared with colonoscopy was found to have a kappa = .829 (P < .001; 95% confidence interval, .629, 1.21). CONCLUSIONS Follow-up colonoscopy should be performed when a CT scan suggests malignancy, nonspecific inflammatory findings, or the patient is otherwise due for routine screening or surveillance. In this study, there was no benefit of follow-up colonoscopy in patients with CT-confirmed diverticulitis in the absence of other concerning or indeterminate findings.
