From the Guidelines

Pain management for diverticulitis should prioritize a combination of acetaminophen, lifestyle adjustments, and avoidance of NSAIDs to minimize complications and promote healing. When considering pain management for diverticulitis, it's essential to focus on treatments that reduce inflammation and discomfort without exacerbating the condition. For mild to moderate pain, acetaminophen at 650-1000mg every 6 hours is recommended as a first-line treatment. Non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen should be avoided during acute flares as they may increase the risk of complications, as noted in the context of managing diverticulitis without specific reference to pain management in the provided evidence 1. In cases of significant pain, prescription medications such as antispasmodics or opioid analgesics may be considered for short-term use. A clear liquid diet during acute flares, applying a heating pad to the abdomen, adequate hydration, and gradual introduction of fiber after acute symptoms resolve are important lifestyle adjustments for managing diverticulitis and its associated pain. These approaches work by reducing inflammation, decreasing intestinal spasms, and allowing the affected colon segment to heal while minimizing further irritation to the inflamed diverticula. Key considerations in pain management include:

  • Avoiding NSAIDs to prevent increased risk of complications
  • Using acetaminophen as a first-line treatment for mild to moderate pain
  • Implementing lifestyle adjustments such as diet and hydration to support healing
  • Considering prescription medications for significant pain under medical supervision. Given the emphasis on managing diverticulitis without antibiotics in uncomplicated cases, as recommended by the 2020 update of the WSES guidelines 1, the focus should be on supportive care and pain management strategies that do not involve antibiotics unless there's a clear indication of complicated diverticulitis.

From the Research

Pain Management for Diverticulitis

  • The management of diverticulitis typically involves a combination of medical and surgical interventions, with pain management being a crucial aspect of treatment 2, 3, 4, 5, 6.
  • For uncomplicated diverticulitis, outpatient treatment is recommended, and antibiotics have no proven benefit in reducing the duration of the disease or preventing recurrence, and should only be used selectively 2, 5, 6.
  • A study comparing oral versus intravenous antibiotics in the treatment of uncomplicated colonic diverticulitis found no significant difference between groups with regards to 30-day unplanned admissions or inflammatory markers, suggesting that oral antibiotics may be a viable option for outpatient management 3.
  • For complicated diverticulitis, non-operative management, including bowel rest and intravenous antibiotics, is indicated for small abscesses, while larger abscesses may require percutaneous drainage or surgical intervention 2, 4, 5.
  • The use of antibiotics in uncomplicated diverticulitis is still a topic of debate, with some studies suggesting that they may not be necessary, while others recommend their use in selected patients 4, 6.
  • A systematic review of randomized controlled trials found that the evidence on antibiotic treatment for uncomplicated acute diverticulitis suggests that the effect of antibiotics is uncertain for complications, emergency surgery, recurrence, elective colonic resections, and long-term complications, with low-quality evidence 6.
  • Pain resolution is an important outcome in the management of diverticulitis, and studies have shown that oral antibiotics can be as effective as intravenous antibiotics in achieving pain resolution and improving symptoms 3.
  • Lifestyle modifications, such as increased intake of dietary fiber, exercise, cessation of smoking, and weight loss, may also play a role in preventing recurrences of diverticulitis 2.
