Should An Early Colonic Evaluation Be Planned In Patients Treated Non
In patients with diverticular abscesses treated non-operatively, we suggest to plan an early colonic evaluation .
In patients with CT-proven uncomplicated diverticulitis treated non-operatively, we do not recommend routine colonic evaluation .
Colonic localized abscess is an uncommon, but possible, presentation of an occult colon malignancy, and it may mimic complicated diverticular disease . It has been demonstrated that the risk of malignancy after a CT-proven uncomplicated diverticulitis is low and, in the absence of other indications, routine colonoscopy may not be necessary. A systematic review investigating the rate of colorectal cancer found by colonoscopy after an episode of uncomplicated diverticulitis was published in 2014 . Nine studies met the inclusion criteria and included a total number of 2490 patients with uncomplicated diverticulitis. Subsequent colonoscopy after an episode of uncomplicated diverticulitis was performed in 1468 patients . Seventeen patients were diagnosed with CRC, having a prevalence of 1.16% . Hyperplastic polyps were seen in 156 patients , low-grade adenoma in 90 patients , and advanced adenoma in 32 patients . The results of this review demonstrate that unless colonoscopy is regarded for screening in individuals aged 50years and older, routine colonoscopy in the absence of other clinical signs of CRC is not required in patients following an episode of acute uncomplicated diverticulitis.
Are Probiotics Helpful In Preventing Diverticulitis
Some researchers believe not having the proper balance of good bacteria in your gut may play a role in the development of diverticulitis. However, right now, theres not enough scientific evidence to prove that probiotics can help prevent diverticulitis. Probiotics may be helpful in preventing constipation however.
What Is The Best Antibiotic For Diverticulitis
In patients with uncomplicated diverticulitis, opt for oral cephalosporin plus metronidazole over antibiotics given using amoxicillin orclavulanic acid. A total of 5ml and 6ml of cefazolin, cefuroxime, or ceftriaxone alone may be used for intravenous therapy with metronidazole or leomycin, together with sulbactam for acute conditions.

Diverticulitis Flare Up: More Conservative Treatment Now Recommended
Diverticulitis is a painful and unpredictable gastrointestinal disease that often requires aggressive treatment. About 200,000 people are hospitalized every year in the United States for the disease, according to the National Institutes of Health.
Diverticulitis occurs when small pouches form in the colon and become inflamed. Symptoms of diverticulitis may include abdominal pain and tenderness, fever, nausea and constipation and they often are irregular.
While patients can develop severe complications from diverticulitis that require surgery, doctors have taken a more conservative approach to treating milder cases. New guidelines from the American Gastroenterological Association call for less emphasis on antibiotics and surgery for mild cases.
What Are The Causes Of Diverticulosis And Diverticulitis
Aging and heredity are primary factors in the development of diverticulosis and diverticulitis, but diet also plays a role. Eating a diet low in fiber and high in refined foods may increase the risk. Indeed, in Western societies, an estimated 10% of people over 40 eventually develop diverticulosis the figure reaches at least 50% in people over 60. Diverticulitis will occur in about 10%-25% of those with diverticulosis.
Though it hasn’t been proven, some researchers think that if you are often constipated and usually strain when you have a bowel movement, you may create enough pressure in the intestinal walls to weaken them and begin the development of diverticular pouches. Another school of thought is that not enough fiber in the diet is responsible. The lack of fiber leads to increased bowel wall strain to move stool through the colon. That then causes increased local pressures that lead to the formation of pouches at weak points in the colon wall. The increased pressure along with undigested food caught in these pouches can erode the diverticular wall, causing inflammation and possible bacterial infection, which can result in diverticulitis.
How Are Diverticulosis and Diverticulitis Diagnosed?
If you think you have either diverticulosis or diverticulitis, talk to your doctor. Your doctor can perform tests to diagnose the conditions including:

In patients with CT findings of distant free gas without diffuse intra-abdominal fluid, we suggest a non-operative treatment in selected patients only if a close follow-up can be performed .
Although most patients hospitalized for acute diverticulitis can be managed by non-operative treatment, up to 25% may require urgent operative intervention . Patients with diffuse peritonitis are typically critically ill patients and require prompt fluid resuscitation, antibiotic administration, and surgery. While the absolute prevalence of perforated diverticulitis complicated by generalized peritonitis is low, it is associated with significant postoperative mortality, regardless of selected surgical strategy.
Highly selected group of patients at this stage may be treated by conservative treatment. However, it may be associated with a significant failure rate and a careful clinical and CT monitoring is mandatory . Suggested intervention for patients at this stage should be surgical resection and anastomosis with or without stoma in stable patients without comorbidities, and Hartmanns procedure in unstable patients or in patients with multiple comorbidities .
What Are The Different Antibiotics For Diverticulitis
When inflammation and infection of the intestinal diverticula occur, there are several antibiotics for diverticulitis a doctor may prescribe to a patient. For relatively mild cases, oral antibiotics are usually sufficient some common ones are ciprofloxacin, metronidazole, and doxycycline. Levofloxacin, moxifloxacin, or cephalexin may also be used. Patients who have more severe cases of diverticulitis may need to be admitted to a hospital where antibiotics can be administered intravenously while their digestive systems are allowed to rest and recover.
One of the most common antibiotics for diverticulitis is ciprofloxacin. This broad spectrum antibiotic is often preferred for treatment of abdominal infections and is typically very effective. Side effects are normally quite mild and limited to issues like nausea and vomiting, rash, or headache, though more serious issues can occur if the medication is not taken as prescribed. Some other types of fluoroquinolone antibiotics, such as moxifloxacin or levofloxacin, may sometimes be used instead.

What Is The Best Imaging Technique In Patients With Suspected Alcd What Is The Role Of Ultrasound In Patients With Alcd
In patients with suspected ALCD, we suggest contrast-enhanced CT scan of the abdomen as the imaging technique of first choice .
We suggest to use US in the initial evaluation of patients with suspected ALCD where it is performed by an expert operator. It has wide availability and easy accessibility. A step-up approach with CT performed after an inconclusive or negative US may be a safe approach for patients suspected of acute diverticulitis .
Radiological imaging techniques that are used for diagnosing ALCD in the emergency setting are US and CT. Currently, CT is the established method of choice when compared to US and most guidelines cite the high accuracy and other advantages of CT. This approach is the gold standard for both the diagnosis and the staging of patients with ALCD due to its excellent sensitivity and specificity . CT scan can also rule out other diagnoses such as ovarian pathology, or leaking aortic or iliac aneurysm.
A systematic review and meta-analysis of studies that reported diagnostic accuracy of the clinical diagnosis and diagnostic modalities in patients with suspected diverticulitis was published in 2014. Summary sensitivity estimates for US were 90% versus 95% for CT . Summary specificity estimates for US were 90% versus 96% for CT .
Magnetic resonance imaging, which is not constrained by the operator dependency limitation of compared to US , until now is currently difficult to perform at in the emergency department.
Understanding What Diverticulitis Is And The Factors That May Cause It
To understand diverticulitis, you must first understand whats going on inside your colon not the most comforting thought, but a necessary one.
Sometimes for reasons not exactly understood small pouches or sac-like protrusions, called diverticula, develop in the colon , most often in the lower part.
One theory behind why these pouches form is straining from constipation. But because diverticula may not cause symptoms, its possible to have one or more without knowing that is, of course, until one of these sacs tears and becomes inflamed or infected.
Diverticulitis means that a sac-like protrusion has become inflamed and generally infected. In other words, diverticulitis means inflamed diverticulosis, explains Will Bulsiewicz, MD, a gastroenterologist and gut health expert in Mount Pleasant, South Carolina. People who develop diverticulitis will have pain in the left lower abdomen, and many will also have nausea with vomiting, fever and a change in bowel habits.
While this condition can affect anyone, the risk is higher if youre older, overweight, eat a low-fiber diet, smoke, dont exercise, or take steroids, opioids, or over-the-counter pain medications like ibuprofen and naproxen.

Do You Need Antibiotics For Diverticulitis
If you have very mild diverticulitis, your doctor should be concerned that antibiotics are not needed even if your condition does not become severe. You should have a liquid diet while you continue your bowel healing process. If your symptoms improve over time, you will be able to gradually add solid foods to your diet.
Should Laparoscopic Lavage And Drainage Be Recommended In Patients With Diffuse Peritonitis Due To Diverticular Perforation
We suggest performing laparoscopic peritoneal lavage and drainage only in very selected patients with generalized peritonitis. It is not considered as the first line treatment in patients with peritonitis from acute colonic diverticulitis .
In 2014, the first results from the RCT DILALA were published . Initial diagnostic laparoscopy showing Hinchey III disease was followed by randomization between laparoscopic lavage and colon resection and stoma. Morbidity and mortality after laparoscopic lavage did not differ when compared with the Hartmann procedure. Laparoscopic lavage resulted in shorter operating time, shorter time in the recovery unit, and shorter hospital stay with the avoidance of a stoma. In this trial, laparoscopic lavage as treatment for patients with perforated diverticulitis Hinchey III disease was feasible and safe in the short-term. In 2015, the results of SCANDIV study were published . Among patients with likely perforated diverticulitis and undergoing emergency surgery, the use of laparoscopic lavage vs. primary resection did not reduce severe postoperative complications and led to worse outcomes in secondary endpoints. These findings do not support laparoscopic lavage for treatment of perforated diverticulitis. In the same year, the result of LADIES study was published. This showed that laparoscopic lavage was not superior to sigmoidectomy for the treatment of purulent perforated diverticulitis .

Which Medications Are Used To Treat Diverticulitis
Diverticulosis is treated with lifelong dietary modification. However, antibiotics have been the mainstay of therapy for most patients with acute diverticulitis, but more recently, their necessity has been questioned, especially in mild, uncomplicated disease. It appears that antimicrobial use in acute uncomplicated diverticulitis increases patients’ stay in the hospital without lowering the overall or individual complication rates. Other studies have shown that the effectiveness of single- or multiple-agent antibiotic regimens for outpatient therapy are essentially the same when they provide both anaerobic and aerobic coverage.
Empiric therapy requires broad-spectrum antibiotics effective against known enteric pathogens. For complicated cases of diverticulitis in hospitalized patients, carbapenems are the most effective empiric therapy because of increasing bacterial resistance to other regimens.
Potential regimens include the following:
- Ciprofloxacin plus metronidazole
Should Antibiotics Be Recommended In Immunocompetent Patients With Uncomplicated Acute Diverticulitis
In immunocompetent patients with uncomplicated diverticulitis without signs of systemic inflammation, we recommend to not prescribe antibiotic therapy .
In patients requiring antibiotic therapy, we recommend oral administration whenever possible, primarily, because an early switch from intravenous to oral therapy may facilitate a shorter inpatient length of stay .
The definition of uncomplicated acute diverticulitis is often vague and poorly defined. Uncomplicated acute diverticulitis is defined as localized diverticular inflammation without any abscess or perforation. A universally accepted classification divides intra-abdominal infections into complicated and uncomplicated . In uncomplicated IAIs, the infection only involves a single organ and does not extend to the peritoneum, while in complicated IAIs, the infectious process extends beyond the organ, causing either localized or diffuse peritonitis . For a better definition of acute diverticulitis in these guidelines, we use the term complicated and uncomplicated according to the classification of IAIs.
Uncomplicated acute diverticulitis is an anatomically confined inflammatory process. CT findings include diverticula, thickening of the wall, and increased density of the pericolic fat. Patients with uncomplicated diverticulitis usually have an indolent course with a low incidence of subsequent complications.

Nonsurgical Treatment For Diverticular Disease
Most people with diverticulosisin which small pouches, called diverticula, form on the colon walldo not have symptoms and do not need treatment. If the diverticula become infected, a common complication called diverticulitis, our specialists offer state-of-the-art treatment options to help you recover.
Most of the time, diverticulitis does not require surgery. If mild, the condition can sometimes be treated with medication and dietary changes.
In more severe diverticulitis, when a perforation or an abscess is suspected, you may experience significant abdominal pain, an inability to tolerate food, constipation, or fever and chills. In this situation, NYU Langone doctors may recommend hospitalization for treatment and monitoring.
Is It Time To Change Practice
The answer to this question will depend in large part on your current practice, but even before this most recent RCT, my approach to diverticulitis had changed. These trials suggest that it is not all that important for me to make the diagnosis of uncomplicated diverticulitis. For many well appearing patients with left lower quadrant pain in whom I would have ordered imaging for diverticulitis in the past, I now forgo imaging. I treat the patients symptoms, often check some labs, and perform a repeat exam. If there are no indications of complicated disease, I will frequently just treat their symptoms with NSAIDs and a few days of modified diet, whether or not their official diagnosis is diverticulitis. Knowing that antibiotics dont seem to help, I now reserve the CT for situations where the patient is not improving or appears unwell, to look for complications or an alternative diagnosis.
Based on the lack of evidence, the American Gastroenterological Association Institute guidelines suggest that antibiotics should be used selectively, rather than routinely, in patients with acute uncomplicated diverticulitis. . Unfortunately, the guideline doesnt really provide any further advice on what selectively means, so it is hard to know who should and shouldnt be treated. Similar guidelines suggesting more selective use of antibiotics have been released by numerous other organizations.

Are Antibiotics Necessary For Diverticulitis
Diverticulitis is a common condition. More than 100,000 adults are hospitalized each year with acute diverticulitis. A far greater number have mild diverticulitis and are treated without hospitalization. The cornerstone of outpatient treatment is antibiotics, typically given for 7-10 days.
However, recent guidelines published by the American Gastroenterology Association question the need for antibiotics in all cases of uncomplicated diverticulitis, and urge selective use. This recommendation, which is a major shift from long established practice, is based largely on a single randomized trial from Sweden and Iceland. In this study*, 669 patients with uncomplicated diverticulitis were randomized to treatment with or without antibiotics. The use of antibiotics did not affect outcomes, including time to symptom resolution, complications, or recurrence. This is surprising, considering that diverticulitis is traditionally viewed as an infection. But in all likelihood, its more an inflammatory, rather than infectious process.
The AGA recommendations cite low quality evidence in support of their recommendation, so we need to be cautious in interpreting it. Further studies are certainly needed. And we need to acknowledge the limitations of the existing study, which may not be reflective of real life all patients had CT scans to confirm the diagnosis and every patient was hospitalized for observation, which is not typical for mild disease.
How Is Diverticulitis Treated
If your diverticulitis is mild, your healthcare provider will prescribe an oral antibiotic, such as metronidazole , trimethoprim-sulfamethoxazole , ciprofloxacin or amoxicillin and clavulanic acid . Rest, taking over-the-counter medications for pain and following a low-fiber diet or a liquid diet may be recommended until your symptoms improve. Once your symptoms improve, you can slowly return to soft foods, then a more normal diet, which should be one that includes many high-fiber foods. You and your healthcare provider will discuss the specifics of your treatment plan.
If your diverticulitis is severe, you have rectal bleeding or are having a repeat bout of diverticulitis, you may be admitted to the hospital to receive intravenous antibiotics, IV fluids or possibly be considered for surgery.

Which Are The Principles Of The Treatment Of Acute Right
Although studies have shown that the percentage of complications requiring surgery is higher in patients with ALCD than in patients with ARCD, the principles of diagnosis and treatment of patients with ARCD are similar to those with ALCD. We suggest that all the statements for ALCD also apply to ARCD.
Acute colonic diverticulitis is a common condition affecting the adult population. Traditionally, the sigmoid colon is considered the most commonly involved part, and ARCD is much rarer . However, in some regions of the world, ARCD outnumber ALCD . The ARCD differs from the ALCD in some aspects. The former is usually solitary , and has a low rate of complicated diverticulitis .
ARCD generally occurs in middle-aged men, and its incidence does not increase with age. Especially the ARCD located in the cecum, it is difficult to distinguish ARCD from acute appendicitis because of their similar symptoms and signs.
CT scanning appears to be the best overall imaging modality in the diagnosis of possible ARCD . However, US is more economic than CT and poses no radiation, which may be particularly important since the patients having right-sided diverticulitis are relatively younger.
US features, including diverticular wall thickening, surrounding echogenic fat, and intra-diverticular echogenic material, can provide clear information for making correct preoperative diagnosis. However, US is operator dependent. Ambiguous US studies may be complemented with a contrast-enhanced CT .
