Sealed perforation of colonic diverticulum is a common clinical condition and may be differentiated from an underlying malignant perforation using interval endoscopy. We present an uncommon colonoscopy finding of a healed diver
A middle-aged Chinese female presented with a 3-d history of non-colicky left iliac fossa pain. It was associated with fever (Tmax 37.6 ºC), non-bloody diarrhoea and non-bloody, non-bilious vomiting. She had a history of Type 2 diabetes mellitus, well controlled on metformin. Tenderness was noted on the left iliac fossa region with no guarding or mass. Total white cell count (11.45 × 109/L) and C-reactive protein levels (213.9 mg/L) were elevated. Computed tomography imaging of the abdomen revealed pericolonic fat stranding and extraluminal air pockets fluid density with peritoneal thickening at the sigmoid colon, likely representing a sealed perforation. Six weeks after the episode, she underwent a follow-up colonoscopy. An exophytic polypoid lesion closely associated with a diverticulum was seen in the sigmoid colon. The lesion was easily “pinched” off without much effort using endoscopic forceps and sent for histology which revealed granulation tissue suggesting a healed diverticular perforation.
Granulation tissue associated with healed diverticular perforations resemble polyps. Tattooing around these sites may allow for future targeted colonic resections.
Core Tip: This case report aims to shed light on the possible morphology of a healed diverticular perforation. This is important as patients who have suffered from diverticular perforations are at increased risk of recurrence, with high likelihood of the previously perforated diverticulum being the offending cause. Recognising the appearance of granulation tissue from a possible sealed perforated diverticulum and marking the site with injectable tattoos may allow for targeted resections of the colon if recurrence occurs. This preserves more parenchyma, allows for a potentially faster surgery, and shortens recovery time while achieving an equivalent improvement in quality-of-life.
