Diverticulitis complicated by colovenous fistula formation and pylephlebitis

Abstract

Acute diverticulitis is associated with a range of complications including fistula formation. Colovenous fistula formation, where there is a fistula between the inferior mesenteric vein and colon, is an extremely rare and serious complication of diverticulitis. Pylephlebitis, which is defined as infective suppurative thrombosis of the portal vein, is another uncommon complication of any intra-abdominal source of infection, including diverticulitis. Both complications are independently associated with significant morbidity and mortality. We report a case of a patient with acute diverticulitis who subsequently developed both colo-venous fistula and pylephlebitis and was successfully managed conservatively.

A Rare Simultaneous Occurrence of Appendiceal Diverticulitis and Peptic Ulcer that Leads to Abdominal Peritonitis Symptoms

“…Different cases of appendiceal diverticula with different symptoms and complications have been reported, including patients of various ages and with different health conditions [2,6,7]. This disease is classified into two groups based on the number of layers herniating through the appendix wall.…”

A rare simultaneous occurrence of appendiceal diverticulitis and non‐perforated peptic ulcer mimicking abdominal peritonitis symptoms

“…Different cases of appendiceal diverticula with different symptoms and complications have been reported, including patients of various ages and with different health conditions. 2 , 6 , 7 This disease is classified into two groups based on the number of layers herniating through the appendix wall. Acquired or pseudodiverticula form and congenital or true form, which means all three appendiceal layers herniate through a normal wall histologically.…”

Right-sided colopleural fistula secondary to diverticular disease: a case report

“…Colopleural fistulas are a rare complication mostly attributed to trauma, iatrogenic injury, Crohn’s disease, or gastrointestinal malignancy [ 1 – 4 ]. Fistulization can also complicate diverticular disease, affecting 4–20% of these patients [ 5 ]. Diverticular fistulas tend to arise from the left side, connecting the large bowel with surrounding structures, such as the small bowel, the urinary bladder, the genitalia, the skin, and in rare cases, the pleural space [ 6 , 7 ].…”
