432

Results

From February 5, 2019 to September 7, 2020, 432 patients were enrolled and assigned to the antibiotic
group (n = 216) or nonantibiotic group (n = 216). After withdrawal of 52 patients, 192 in the antibiotic group
and 188 in the nonantibiotic group were analyzed. PECS occurred in 9 of 192 patients (4.7%) in the antibiotic
group and 14 of 188 patients (7.5%) in the nonantibiotic group, with an odds ratio of .61 (95% confidence interval,
.23-1.56; P = .29).

Baseline Characteristics

Background characteristics of patients (sex and location)
were comparable between the antibiotic and nonantibiotic
groups, including the number of patients taking
nonsteroidal anti-inflammatory drugs. Median
tumor size was 30 mm in both groups. Previous biopsy
samples of the lesions were performed in 52 (27%) and
42 (22%) patients in the antibiotic and nonantibiotic
groups, respectively. Three of these samples were local
recurrent lesions after endoscopic resection and the
others were naive tumor. No tumor on the anastomosis
site was included.

Participant flow

Trial recruitment was conducted from February 5, 2019
to September 7, 2020, and follow-up was completed on
October 8, 2020. Of 464 recruited patients, 32 declined
to participate were excluded, and 432 patients were
enrolled and assigned to either the antibiotic group
(n=216) or nonantibiotic group (n=216) at 21 Japanese
tertiary institutions.

Adverse events

Perforation occurred in 10 patients (5.0%, 8 intraprocedural and 2 delayed perforations) in the antibiotic group
and in 12 patients (6.0%, 8 intraprocedural and 4 delayed
perforations) in the nonantibiotic group. All perforation
cases could be managed conservatively without surgical
intervention, and no significant difference was confirmed
between the 2 groups. Twelve patients
developed other adverse events (5.9%, 9 post-ESD
bleeding, 1 hemorrhoidal bleeding, 1 chronic cholecystitis,
and 1 reflux esophagitis) in the antibiotic group, and
adverse events occurred in 11 patients (5.5%, 7 post-ESDbleeding, 1 ileus, 1 bacteremia, 1 arrhythmia, and 1 cystitis)
in the nonantibiotic group (P =.83).

Outcome measures

PECS occurred in 9 of 192 patients (4.7%) in the antibiotic
group (interventional group) and 14 of 188 patients
(7.5%) in the nonantibiotic group, with an odds ratio of .61
(95% confidence interval [CI], .23-1.56; P = .29)
when analyzed by the PPS. By intention to treat analysis,
PECS occurred in 9 of 214 patients (4.2%) in the
antibiotic group and in 14 of 213 patients (6.6%) in the
nonantibiotic group, with an odds ratio of .62 (95% CI,
.27-1.44; P = .29). White blood cell counts on the day
after ESD were 7400 cells/mL and 8100
cells/mL in the antibiotic and nonantibiotic groups,
respectively (P < .001). The time from ESD to discharge
was 3.4 days (95% CI, 3.2-3.6) and 3.6 days (95% CI, 3.3-
3.8) in the antibiotic and nonantibiotic groups,
respectively (P = .39).
