Review
INTRODUCTION
Diverticula (mucosal outpouching through the wall of the colon) affect over 5% of adults aged 40 years and older, but only 10-25% of affected people will develop symptoms such as lower abdominal pain. Recurrent symptoms are common, and 5% of people with diverticula eventually develop complications such as perforation, obstruction, haemorrhage, fistulae, or abscesses.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of: treatments for uncomplicated diverticular disease; treatments to prevent complications; and treatments for acute diverticulitis? We searched: Medline, Embase, The Cochrane Library and other important databases up to July 2006 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found 13 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic review we present information relating to the effectiveness and safety of the following interventions: antispasmodics, bran, elective surgery, increasing fibre intake, ispaghula husk, lactulose, medical treatment, mesalazine, methylcellulose, rifaximin, surgery.

OBJECTIVE
To understand why the population-based incidence of diverticulitis has increased over time, we studied temporal changes in age, body mass index (BMI), and diverticulitis in Olmsted County, Minnesota.
PARTICIPANTS AND METHODS
We compared the BMIs of 2967 patients with diverticulitis and 9795 people without diverticulitis from January 1, 1980, through December 31, 2007. Because BMI is a surrogate for adipose tissue, computed tomographic estimations of abdominal fat content were compared between 381 diverticulitis cases and 381 age- and sex-matched controls.
RESULTS
Between 1980 and 2007, the prevalence of obesity increased from 12% to 49% in the population and from 19% to 40% in patients with diverticulitis (P<.001 for both). Temporal trends in age, BMI, and the increased incidence of diverticulitis in people with normal BMI accounted for 48%, 47%, and 20%, respectively, of corresponding trends in diverticulitis. The secular decline in the proportion of people with normal BMI was partly offset by an increased incidence of diverticulitis in such people. In the case-control study, BMI was greater in cases than in controls (P=.001). However, after incorporating abdominal visceral (odds ratio [OR], 2.4; 95% CI, 1.6-3.7) and subcutaneous (OR, 2.9; 95% CI, 1.7-5.2) fat content (both associated with diverticulitis), BMI was associated with lower risk (OR, 0.8; 95% CI, 0.7-0.8) of diverticulitis.
CONCLUSION
Aging, increasing obesity, and the increased incidence of diverticulitis in people with normal BMI account for the temporal increase in diverticulitis. Rather than BMI per se, increased abdominal visceral and subcutaneous fat are independently associated with diverticulitis. The incidence of diverticulitis, which is among the most common gastrointestinal diagnoses in hospitalized patients, has increased markedly since 2000. This study suggests that aging, increasing obesity, and the increased incidence of diverticulitis in people with normal BMI account for the temporal increase in diverticulitis.

Meta-Analysis
BACKGROUND
Use of antibiotics in selected cases of acute uncomplicated diverticulitis (AUD) has recently been questioned.
OBJECTIVE
The aim of this study is to examine the safety and efficacy of treatment regimens without antibiotics compared with that of traditional treatments with antibiotics in selected patients with AUD.
DATA SOURCES
PubMed, Medline, Embase, Web of Science, and the Cochrane Library.
METHODS
A systematic review was performed according to PRISMA and AMSTAR guidelines by searching through Medline, Embase, Web of Science, and the Cochrane Library for randomized clinical trials (RCTs) published before December 2022. The outcomes assessed were the rates of readmission, change in strategy, emergency surgery, worsening, and persistent diverticulitis.
STUDY SELECTION
RCTs on treating AUD without antibiotics published in English before December 2022 were included.
INTERVENTION
Treatments without antibiotics were compared with treatments with antibiotics.
MAIN OUTCOME MEASURES
The outcomes assessed were the rates of readmission, change in strategy, emergency surgery, worsening, and persistent diverticulitis.
RESULTS
The search yielded 1163 studies. Four RCTs with 1809 patients were included in the review. Among these patients, 50.1% were treated conservatively without antibiotics. The meta-analysis showed no significant differences between nonantibiotic and antibiotic treatment groups with respect to rates of readmission [odds ratio (OR)=1.39; 95% CI: 0.93-2.06; P =0.11; I2 =0%], change in strategy (OR=1.03; 95% CI: 0.52-2,02; P =0.94; I2 =44%), emergency surgery (OR=0.43; 95% CI: 0.12-1.53; P =0.19; I2 =0%), worsening (OR=0.91; 95% CI: 0.48-1.73; P =0.78; I2 =0%), and persistent diverticulitis (OR=1.54; 95% CI: 0.63-3.26; P =0.26; I2 =0%).
LIMITATIONS
Heterogeneity and a limited number of RCTs.
CONCLUSIONS
Treatment for AUD without antibiotic therapy is safe and effective in selected patients. Further RTCs should confirm the present findings.

Meta-Analysis
This study aimed to investigate the estimated rate and risk of recurrence of uncomplicated diverticulitis (UCD) after the first episode through a meta-analysis. Eligible studies were searched and reviewed; 27 studies were included in this study. Subgroup analyses were performed, based on lesion location, medical treatment, follow-up period, and study location. The estimated recurrence rate of UCD was 0.129 (95% confidence interval [CI] 0.102-0.162). The recurrence rates of the right-and left-sided colon were 0.092 (95% CI 27.063-0.133) and 0.153 (95% CI 0.104-0.218), respectively. The recurrence rate according to follow-up period was highest in the subgroup 1-2 years, compared with that of other subgroups. The recurrence rate of the Asian subgroup was significantly lower than that of the non-Asian subgroup (0.092, 95% CI 0.064-0.132 vs. 0.147, 95% CI 0.110-0.192; = 0.043 in the meta-regression test). There were significant correlations between UCD recurrence and older age and higher body temperature. However, UCD recurrence was not significantly correlated with medications, such as antibiotics or anti-inflammatory drugs. In this study, detailed information on estimated recurrence rates of UCD was obtained. In addition, older age and higher body temperature may be risk factors for UCD recurrence after the first episode.

Observational Study
BACKGROUND
Diverticular disease can undermine health-related quality of life. The diverticulitis quality of life (DV-QOL) instrument was designed and validated to measure patient-reported burden of diverticular disease. However, values reflecting meaningful improvement (i.e., minimal clinically important difference [MCID]) and the patient acceptable symptom state (PASS) have yet to be established. We sought to establish the MCID and PASS of the DV-QOL and describe the characteristics of those with DV-QOL above the PASS threshold.
MATERIALS AND METHODS
We performed a prospective cohort study of adults with diverticular disease from seven centers in Washington and California (2016-2018). Patients were surveyed at baseline, then quarterly up to 30 mo. To determine the MCID and PASS for DV-QOL, we applied various previously established distribution- and anchor-based approaches and compared the resulting values.
RESULTS
The study included 177 patients (mean age 57 y, 43% women). A PASS threshold of 3.2/10 distinguished between those with and without health-related quality of life-impacting diverticulitis with acceptable accuracy (area under the curve 0.76). A change of 2.2 points in the DV-QOL was the most appropriate MCID: above the distribution-based MCIDs and corresponding to patient perception of importance of change (AUC 0.70). Patients with DV-QOL ≥ PASS were more often men, younger, had Medicaid, had more serious episodes of diverticulitis, and had an occupational degree or high-school education or less.
CONCLUSIONS
Our study is the first to define MCID and PASS for DV-QOL. These thresholds are critical for measuring the impact of diverticular disease and the evaluation of treatment effectiveness.

Langenbeck's Archives of Surgery Feb 2022In the last two decades, there has been a Copernican revolution in the decision-making for the treatment of Diverticular Disease.
BACKGROUND
In the last two decades, there has been a Copernican revolution in the decision-making for the treatment of Diverticular Disease.
PURPOSE
This article provides a report on the state-of-the-art of surgery for sigmoid diverticulitis.
CONCLUSION
Acute diverticulitis is the most common reason for colonic resection after cancer; in the last decade, the indication for surgical resection has become more and more infrequent also in emergency. Currently, emergency surgery is seldom indicated, mostly for severe abdominal infective complications. Nowadays, uncomplicated diverticulitis is the most frequent presentation of diverticular disease and it is usually approached with a conservative medical treatment. Non-Operative Management may be considered also for complicated diverticulitis with abdominal abscess. At present, there is consensus among experts that the hemodynamic response to the initial fluid resuscitation should guide the emergency surgical approach to patients with severe sepsis or septic shock. In hemodynamically stable patients, a laparoscopic approach is the first choice, and surgeons with advanced laparoscopic skills report advantages in terms of lower postoperative complication rates. At the moment, the so-called Hartmann's procedure is only indicated in severe generalized peritonitis with metabolic derangement or in severely ill patients. Some authors suggested laparoscopic peritoneal lavage as a bridge to surgery or also as a definitive treatment without colonic resection in selected patients. In case of hemodynamic instability not responding to fluid resuscitation, an initial damage control surgery seems to be more attractive than a Hartmann's procedure, and it is associated with a high rate of primary anastomosis.

Review
BACKGROUND
The incidence of acute left-sided colonic diverticulitis (ACD) is increasing in the Western world. To improve the quality of patient care, a guideline for diagnosis and treatment of diverticulitis is needed.
METHODS
A multidisciplinary working group, representing experts of relevant specialties, was involved in the guideline development. A systematic literature search was conducted to collect scientific evidence on epidemiology, classification, diagnostics and treatment of diverticulitis. Literature was assessed using the classification system according to an evidence-based guideline development method, and levels of evidence of the conclusions were assigned to each topic. Final recommendations were given, taking into account the level of evidence of the conclusions and other relevant considerations such as patient preferences, costs and availability of facilities.
RESULTS
The natural history of diverticulitis is usually mild and treatment is mostly conservative. Although younger patients have a higher risk of recurrent disease, a higher risk of complications compared to older patients was not found. In general, the clinical diagnosis of ACD is not accurate enough and therefore imaging is indicated. The triad of pain in the lower left abdomen on physical examination, the absence of vomiting and a C-reactive protein >50 mg/l has a high predictive value to diagnose ACD. If this triad is present and there are no signs of complicated disease, patients may be withheld from further imaging. If imaging is indicated, conditional computed tomography, only after a negative or inconclusive ultrasound, gives the best results. There is no indication for routine endoscopic examination after an episode of diverticulitis. There is no evidence for the routine administration of antibiotics in patients with clinically mild uncomplicated diverticulitis. Treatment of pericolic or pelvic abscesses can initially be treated with antibiotic therapy or combined with percutaneous drainage. If this treatment fails, surgical drainage is required. Patients with a perforated ACD resulting in peritonitis should undergo an emergency operation. There is an ongoing debate about the optimal surgical strategy.
CONCLUSION
Scientific evidence is scarce for some aspects of ACD treatment (e.g. natural history of ACD, ACD in special patient groups, prevention of ACD, treatment of uncomplicated ACD and medical treatment of recurrent ACD), leading to treatment being guided by the surgeon's personal preference. Other aspects of the management of patients with ACD have been more thoroughly researched (e.g. imaging techniques, treatment of complicated ACD and elective surgery of ACD). This guideline of the diagnostics and treatment of ACD can be used as a reference for clinicians who treat patients with ACD.

Review
BACKGROUND
Symptomatic diverticular disease is challenging for patients, clinicians and health services. The prevalence increases with age and BMI and as such, the burden of this disease is set to increase with higher rates of acute presentations already documented. The natural history of recurrent episodes, complications and symptom progression is not fully understood. Furthermore, medical and surgical management strategies are under constant appraisal, debate and evolution.
METHODS
A review of the contemporary literature was performed to examine the emerging trend towards conservative treatment.
RESULTS
Routine use of in-patient, intravenous antibiotics may not be required and outpatient management is possible for certain patients. Universal colonoscopy examination after uncomplicated acute diverticulitis is controversial but is mandatory after complicated episodes. Recent, high-profile, clinical trials suggest that less aggressive surgical management of both acute and chronic presentations may be feasible in some cases.
CONCLUSIONS
Diverticulitis is a common yet challenging topic that demands clinicians to provide an individualised yet evidence-based approach.

INTRODUCTION
Acute appendiceal diverticulitis is an unusual cause of acute abdomen, considered clinically indistinguishable from acute appendicitis.
MATERIAL AND METHODS
In a historic cohort study with 27 cases of appendiceal diverticulitis and 54 cases of acute appendicitis, we compared clinical characteristics, diagnostic tests and pathology findings of the two processes.
RESULTS
Mean age at presentation was lower in acute appendicitis (37.24 +/- 19.98 vs. 54.81 +/- 17.55 years, p < 0.001), with significant differences between men (33.33 +/- 15.89 vs. 57 +/- 18.02 years, p < 0.001) but not between women (41.76 +/- 24.87 vs. 50.44 +/- 16.69 years, p = 0.34). In the diverticulitis group, 48.15 % had leukocytosis vs. 81.48 % in the appendicitis group (p = 0.02); there was no difference in leukocyte count (13770.37 +/- 4382.55 vs. 14279.63 +/- 4268.59, p = 0.61). Patients with appendiceal diverticulitis had a higher incidence of appendiceal mucocele (p = 0.01) and a lower proportion of appendiceal gangrene (p = 0.03). There were no differences in appendiceal perforation or ulceration. Symptom duration before emergency department attendance (71.61 +/- 85.25 hours vs. 36.84 +/- 33.59 hours; Z = -3.1 p = 0.002), duration of surgery (85 +/- 40 minutes vs. 60 +/- 21 minutes, Z = -3.2, p = 0.001) and the presence of appendicular plastron was higher in patients with diverticulitis vs. appendicitis (8 vs. 5 patients [p = 0.01, Odds ratio 2.2]).
CONCLUSIONS
Appendiceal diverticulitis presents a series of clinical, epidemiological and pathological differences with respect to acute appendicitis. The former shows a more indolent course with delayed diagnosis.
