Complications related with colonic diverticulitis are:
- abscess formation
- fistula formation
- bladder: colovesical fistula
- vagina: colovaginal fistula
- bowel: coloenteric fistula or colocolic fistula
- skin: colocutaneous fistula
- small bowel obstructions from adhesions
- perforation resulting in pneumoperitoneum
In this case, radiology has been asked to insert a percutaneous catheter for the abscess drainage.
