Case series of novel motorized spiral enteroscopy

No.	Age/sex	Indication for enteroscopy	Route of enteroscopy	Successful (target reached)	Time taken	Findings	Histopathology findings	Procedures performed	Adverse effects
1	28/M	Distal jejunal and proximal ileal strictures on CT enterography	Anterograde and retrograde	Yes	30 min 40 min	Distal jejunal stricture, proximal ileal stricture with nodularity and ulceration	Crohn’s enteritis	Biopsy	–
2	60/M	Short-segment wall thickening in distal jejunum and proximal ileum on CT enterography	Anterograde	Yes	15 min	Mid-jejunal stricture with ulcers	Crohn’s enteritis	Biopsy	–
3	64/M	Long-segment thickening in proximal ileum; multiple large mesenteric nodes on CT enterography	Retrograde and push enteroscopy anterograde	Yes	75 min	Proximal ileal stricture	Crohn’s enteritis	Balloon dilatation and biopsy	–
4	44/M	Thickening with mucosal enhancement of proximal jejunal loops on CECT abdomen	Anterograde	Yes	30 min	Tight stricture in distal jejunum with preceding clean-based ulcer	Crohn’s jejunitis	Biopsy	–
5	36/M	End-stage renal disease; retrieval of retained capsule endoscope due to proximal ileal stricture	Retrograde; patient did not consent to anterograde	Yes	180 min	Proximal ileal stricture noted	Nonspecific ileitis	Balloon dilation; procedure abandoned because patient could not tolerate the prolonged anesthesia. Plan to repeat later.	Hypothermia
6	25/M	Skip areas of circumferentially enhancing wall thickening in mid- and distal ileum	Anterograde and retrograde (panenteroscopy confirmed by tattooing)	Yes	60 min 90 min	Normal study	–	Panenteroscopy	–
7	44/F	Subacute intestinal obstruction, with history of appendectomy and cesarean section; high CRP and fecal calprotectin	Anterograde could not be done because the spiral segment could not pass beyond the cricopharynx. Retrograde approach was difficult, probably because of adhesions—150 cm of ileum reached.	Yes	85 min	Distal ileal narrowing with erosions	Crohn’s ileitis	Biopsy	–
8	82/F	Recurrent obscure GI bleeding	Anterograde could not be done because of a short neck. Hence retrograde was done. Tattooing and push enteroscopy were done anterograde and panenteroscopy confirmed.	Yes	80 min	Angiectasias in ileum and jejunum	–	APC	–
9	63/M	Obscure GI bleeding	Anterograde—cecum reached	Yes	105 min	Ileal ulcers with bleeding	Crohn’s ileitis	APC	–
10	80/F	Obscure GI bleeding	Anterograde and retrograde	Yes	90 min 110 min	Jejunal and ileal angiectasias	–	APC	Hypothermia
11	50/M	Midjejunal stricture	Anterograde	Yes	30 min	Mid-jejunal stricture	Crohn’s jejunitis	Biopsy	–
12	65/M	Short segment of distal jejunal loop adherent to anterior abdominal wall in left iliac fossa region	Anterograde and retrograde	Yes	100 min 60 min	Ileal ulcer	Nonspecific ileitis	Biopsy	–
13	58/F	Long-segment wall thickening in distal jejunum and proximal ileum	Anterograde (not progressing beyond jejunum) and retrograde (nonprogression beyond ileocecal valve)	No	–	Small jejunal ulcers and erosions	Nonspecific jejunitis	Biopsy	Hypothermia and pancreatitis
14	79/M	Obscure occult GI bleeding	Anterograde—panenteroscopy confirmed by reaching cecum	Yes	90 min	Normal	–	–	–

CECT, Contrast-enhanced computerized tomography; APC, argon plasma coagulation; CRP, C-reactive protein.
