A 31-year-old man with a 2-day history of periumbilical abdominal pain was evaluated at our hospital. Abdominal computed tomography (CT) revealed ileocecal inflammation and multiple cecal diverticula ([Fig. 1] a). Colonoscopy identified several diverticula in the cecum, particularly one manifesting inflamed and edematous mucosa coated in yellowish-white purulent exudate ([Fig. 1] b). A continuous purulent discharge was noted.

Upon obtaining informed consent, we embarked upon endoscopic direct diverticulitis therapy (EDDT), using a digital single-operator cholangioscope (DSOC) (EyeMax, 3.3 mm; Micro-Tech, Nanjing, China). This revealed a substantial volume of fecaliths in the diverticular cavity ([Fig. 2] a, [Video 1]). These fecaliths were meticulously fragmented, extracted, and removed using a disposable basket ([Fig. 2] b) and biopsy forceps ([Fig. 2] c), following repeated lavages with metronidazole and sodium chloride. This left the diverticular mucosa cleansed though characterized by roughness and swelling, without evidence of perforation ([Fig. 2] d). A 7-Fr pancreatic duct stent was strategically placed to ensure unobstructed drainage ([Fig. 3]).

The patient’s postoperative course was marked by rapid alleviation of abdominal discomfort, a decline in routine hematological and C-reactive protein (CRP) levels, and diminished inflammation on subsequent CT imaging ([Fig. 4]).

Fig. 4 Postoperative CT demonstrated the reduction in the severity of ileocecal inflammatory exudation compared to before the procedure.

Acute diverticulitis is mainly treated through medication and surgical intervention [1]. The use of a DSOC has proven effective for managing inflammations in natural conduits such as the bile duct, pancreatic duct, and appendix [2] [3]. To the best of our knowledge, this is the first report of the use of a DSOC to treat acute diverticulitis, illustrating its potential for precise, minimally invasive therapy. The direct visualization and management of diverticular contents offers a safe, efficient alternative to traditional interventions, with the promise of shorter hospital stays and rapid recovery. This novel EDDT approach could reshape the management of acute diverticulitis, emphasizing the importance of technological integration into endoscopic practice.
