== | ==Overview== | ||
Diverticulitis, is the inflammation of the diverticula present in the diverticular disease, causing fever, leukocytosis and lower abdominal pain. It could be simple or complicated, which includes gross or microscopical perforation, obstruction, the formation of abscesses or fistulization. | |||

Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated. [[Diverticulitis]] is a life-threatening condition and must be treated as such irrespective of the causes. | |||

Overview
Diverticulitis, is the inflammation of the diverticula present in the diverticular disease, causing fever, leukocytosis and lower abdominal pain. It could be simple or complicated, which includes gross or microscopical perforation, obstruction, the formation of abscesses or fistulization.
Causes
Life Threatening Causes
Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated. Diverticulitis is a life-threatening condition and must be treated as such irrespective of the causes.
Common Causes
- Diverticular Disease
- Increased intracolonical pressure
- Constipation
Management
Diagnostic Approach
Shown below is an algorithm depicting the diagnostic approach to diverticulitis according to the American Society of Colon and Rectal Surgeons[1] and the American Journal of Gastroenterology[2]
Characterize the symptoms:[3]
❑ Abdominal fullness | |||||||
Obtain a detailed history:[4] ❑ Age
| |||||||
Examine the patient: ❑ Vital signs
| |||||||
Consider alternative diagnoses: ❑ Urinary tract infection | |||||||
Order labs:[3] ❑ Complete blood count Order imaging studies:
❑ Abdominal X-rays with soluble contrast | |||||||

Initial Management | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Uncomplicated | Complicated[7] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Outpatient ❑ Inmunocompetence ❑ Tolerated oral intake ❑ Single episode ❑ Mild to moderate pain | Hospitalized ❑ Immunocompromise ❑ Unable to tolerate oral intake ❑ Severe pain | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Medical treatment[3] ❑ Administer oral broad spectrum antibiotics for 7 days
| Medical treatment[3] ❑ Administer intravenous broad spectrum antibiotics
❑ Keep nothing by mouth | Stage the severity by using: | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||
❑ No response to treatment in 2-3 days | Mild | Moderate | Severe | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
❑ Repeat CT scan ❑ Obtain a surgical consult | Hinchey Stage I ❑Small precolic abscess (<4cm in diameter) ❑Without peritonitis | Hinchey Stage II ❑Peridiverticular abscess (>4cm in diameter) | Hinchey Stage III and IV ❑Generalized peritonitis | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Treat conservatively ❑ Bowel rest ❑Broad - spectrum antibiotics intravenously ❑Pain control | Percutaneous Drainage ❑ Bowel rest ❑Broad - spectrum antibiotics intravenously ❑CT-guided percutaneous drainage ❑Pain control | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Do´s
- Do perform colonoscopy and sigmoidoscopy, approximately six weeks after the inflammatory process, in order to rule out other diseases.
- Do insert a nasogastric tube if evidence of obstruction or ileus.
- Do perform a percutaneous drainage if planning for a successful one stage procedure.
- Do perform Laparoscopic surgery, as it tends to shorter hospital stays, less post-operative pain and reduced overall risk of complications.[9]
- Do perform elective surgery after first diverticulitis episode in immunocompromised patients, as they are at higher risk for perforation and abscesses formation.[10]
- Do perform urinalysis and plain abdominal X-rays to differentiate urinary track infections, kidney stones and bowel obstruction.
- Do use ultrasound and MRI are useful alternative in the initial evaluation.
- Do perform percutaneous drainage in patients with fever >101.2°F or abscesses >6.5cm in diameter.[11]
- Do recommend elective single stage colectomy for patients who undergo percutaneous drainage, although decision should be individualized and risk of operative surgery should be considered.
- Do consider the use of ureteral stents in complicated cases such as patients who are morbidly obese, patients who have been irradiated, patients undergoing reoperation or in cases of abnormal anatomy.[12]
- Do consider the administration of non-absorbable oral antibiotics such as erythromycin, neomycin, flagyl and clindamycin before elective color resection as well as mechanical bowel preparation, as they may reduce surgical site complications.[13] [14]
- Do perform emergency surgery on patients with chronic renal failure or collagen vascular disease, as they have high risk of recurrence con complicaed diverticulitis.[15]
- Do perform urgent sigmoid colectomy on patients with diffused peritonitis.
Don'ts
- Do not perform colonoscopy and sigmoidoscopy, when suspecting acute diverticulitis, because of the risk of perforation.
- Do not reverse a colostomy in elderly patients due to the increased risk of anastomotic leakage, small bowel trauma, or incisional herniation.[16]
- Do not recommend elective resection solely on the patients age (<50 years old).
- Do not recommend laparoscopic lavage to patients with purulent or fecal peritonitis.
- Do not perform ultrasounds on patients with abdominal tenderness as it requires compression.[14]
