CD complicated by small intestinal obstruction with capsule endoscopic incarceration (Case 1). (A) Abdominal plain film: the jejunum in the upper left abdomen was dilated, and the intestinal cavity contained a gas-liquid plane. Metallic shadows could be seen in the overlapping area of the pelvic cavity. (B) Intraoperative exploration: the capsule endoscope is incarcerated in the narrowed proximal ileum (Arrow point). (C,D) The specimen of surgery: the yellow cylinder is capsule endoscope; vascular clamp showing internal fistula.

Moreover, metallic shadows could be seen in the overlapping area of the pelvic cavity (Figure 1A). Endo-GI was used to resect the intestinal cavity at the beginning of ascending colon, dragging out the narrowed ileum, capsule endoscope incarcerated in the proximal ileum was touched (Figure 1B). The surgical specimen was inspected, and the multiple polyps of the intestinal wall and capsule endoscope were removed (Figures 1C,D).

Intestinal obstruction caused by CD combined with internal hernia and ileal stenosis (Case 2). (A-C) CT scans of abdomen: intestinal tract lesions in the right middle and lower abdomen, causing a proximal small intestinal obstruction. (D-F) Endoscopic examination: noticeable mucosal swelling, irregular fissure ulcers, and multiple polypoid hyperplasias in the sigmoid colon (18 cm away from the anus). The intestinal cavity was so narrowed that the endoscope could not pass through it. (G) Intraoperative exploration: the proximal small intestine passed through the transverse mesocolon, causing the formation of the internal hernia. (H-I) The specimen of surgery.

CT scans of the abdomen showed intestinal tract lesions in the right middle and lower abdomen, causing a proximal small intestinal obstruction (Figures 2A-C). The intestinal cavity was so narrowed that the endoscope could not pass through it (Figures 2D-F). The proximal small intestine passed through the transverse mesocolon, causing the formation of an internal hernia (Figure 2G). The surgical specimen was inspected, as shown in Figures 2H,I.
