1 Symptomatic Small Bowel Obstruction due to Capsule Impaction
경북대학교병원

2 Case 조○순, 여/69 C/C : P/I Lower abdominal pain for 5 months
2001년 타 병원에서 ulcerative colitis 진단 평상시 월 1-2차례 정도의 하복부 불편감 외 특이 소견 없이 지내옴 2006년 11월부터 가정 문제로 심한 스트레스 받던 중에

3 Case 하복부 통증 심해지면서 주 1-2회 정도 발생하였으며, 통증 있을 때마다 가까운 병원에서 NSAID inj. 해 옴.
2007.2월경부터 pain 더 악화되어 거의 매일 증상 발생하여 pain에 대한 work-up 위해 입원. Abd. Pain – dull to colicky nature, periumbilical to lower abdomen, 1-2시간 지속, 식후 다소 악화 Hematochezia (-), Diarrhea (-) Febrile/chilling sensation (-/-)

4 Case Personal Hx. : Alcohol/Smoking (-/-) Past Hx. : Unremarkable
Physical Exam. G/A; not so ill apperance Face; not pale, anicteric Chest Heart; Regular /s murmur Lung; Clear /s rale

5 Case Laboratoy findings Abdomen Ext; No pitting edema
Soft and flat T/RT (-/-) Ext; No pitting edema Laboratoy findings CBC 3790/13.3/291,000 AST/ALT 23/23 ALP/GGT 75/11 Na/K 140/3.8 BUN/Cr 10.2/0.56

6 EGD

7 Colonoscopy

8 ABD-Pelvic CT Colon에 많은 양의 fluid가 남아있으며 air fluid level을 보임.
Lower abdomen과 pelvic cavity에 걸쳐 small bowel loop의 segmental mucosal layer의 thickening과 hyperenhancement가 있음. Fluid filled dilatation을 보이며 perienteric infiltration 보이지 않음. Circumferential involvement를 보임. Distal jejunum 또는 proximal ileum으로 생각됨. Several enlaregd mesenteric lymph nodes가 있음.

9 Capsule Endoscopy

10 Capsule Endoscopy

11 Capsule Impaction After 48hrs After 1 week After 2 weeks

12 Impaction 발생 후 20일째 severe lower abdominal pain 및 nausea 호소하여 CT 촬영 후에 Small bowel segmental resection + Capsule removal 시행함.

13 Capsule Impaction - CT Pelvic cavity에 distal small bowel의 segmental wall thickening이 있으며 intraluminal high density가 보이며 foreign body, capsule endoscopy의 가능성이 있음. Transition zone에 위치하고 있어 stricture site에 걸린 것으로 생각됨. Mesentery에 enlarged lymph node가 있음. 이전 CT에서 ulcerative colitis의 small bowel involvement의 가능성을 이야기 하였으며 드물지만 small bowel의 adenocarcinoma의 가능성도 생각하여야겠음. Capsule endoscopy라면 수술을 권함.

14 OP Finding

15 Capsule Impaction Defined as retension of the capsule in the small bowel for 2 weeks or longer. Distinguish from regional transit abnormality Type 1 Capsule stays at same point (>60min, < 2week) No abnormality visible on capsule imaging Type 2 With visible abnormality

16 Capsule Impaction Capsule impaction rate; 0.75%
0% in asymptomatic healthy volunteers 3.5~6% in obscure GI bleeding or anemia 1~2% in suspected Crohn’s diasea 4~13% in known Crohn’s diease 21% in suspected small bowel obstruction

17 Capsule Impaction Occurs at sites of structural abnormality in the small bowel Ulcer or mass, Stricture caused by Crohn’s diease, nonsteroidal anti-inflammatory drug use, radiation colitis or surgical anastomosis No reported cases occuring in a normal small intestine Asymptomatic
