SBE procedure characteristics
All patients underwent CTE examination before SBE procedure, and
confirmed the presence of polyps≥10mm. As table 2 shows, A total of 129
hospitalizations (including 248 SBE procedures, 126 via oral approach
and 122 via anal approach) were performed in 102 patients. A total of
5390 polys (diameter≥10mm) were resected, including 3616 (67.1%) using
an oral approach and 1774 (32.9%) using an anal approach. The mean
intubation depth was (248.5±62.4) cm and (180.8±32.0) cm for the oral
and anal procedures, respectively. The total enteroscopy rate was 42.4%
(50/118). Regarding the procedure characteristics of children, A total
of 723 polys were resected, including 429 using an oral approach and 294
using an anal approach. The mean intubation depth was (254.5±35.0) cm
and (177.3±26.1) cm for the oral and anal procedures, respectively.
As table 3 shows, the maximum size of the resected polyps via the anal
approach during the second hospitalization was significantly smaller
than that during the first hospitalization ([2.25±1.29] cm vs
[4.26±3.51] cm, P = 0.032). The median number of resected polyps was
38.0(oral approach) and 8.0 (anal approach) during the first
hospitalization, and 27.0 (oral approach) and 4.0 (anal approach) during
the second hospitalization. The
number of resected polyps had a tendency to decrease, although these
results were not statistically significant. As table 4 shows, the
intubation depth via oral approach of patients with history of
laparotomy was significantly shorter than that of the patients without
history of laparotomy ([241.6±64.2] cm vs [280.9±40.2] cm, P =
0.008).
The overall complete treatment rate was 95.3%. For patients with total
enteroscopy, 1 patient presented many large polyps that could not be
resected in one hospitalization. Among the rest patients, all polyps
larger than 10 mm were successfully resected. The complete treatment
rate in these patients was 98%. For patients without total enteroscopy,
1 patient underwent surgical operation for a giant (>5cm)
and wide-base polyp, 1 patient presented a polyp which is a suspect of
malignant tumor in duodenum, and was diagnosed as adenocarcinoma after
surgical operation, 3 patients presented residual polyps. Among the rest
patients, all polyps larger than 10 mm in the examined segment of small
bowel were resected successfully. All polyps suspected to be equal or
larger than 20 mm by CTE were confirmed by SBE. The complete treatment
rate in these patients was 93.7%.
