RESUMO
BACKGROUND/AIMS: Delayed post-endoscopic submucosal dissection (ESD) bleeding (DPEB) is difficult to predict and there is controversy regarding the usefulness of prophylactic hemostasis during second-look endoscopy. This study evaluated the risk factors related to DPEB, the relationship between clinical outcomes and the Forrest classification, and the results of prophylactic hemostasis during second-look endoscopy. METHODS: Second-look endoscopy was performed on the day after ESD to check for recent hemorrhage or potential bleeding and the presence of artificial ulcers in all patients. RESULTS: DPEB occurred in 42 of 581 patients (7.2%). Multivariate analysis determined that a specimen size ≥40 mm (odds ratio [OR], 3.03; p=0.003), and a high-risk Forrest classification (Forrest Ib+IIa+IIb; OR, 6.88; p<0.001) were risk factors for DPEB. DPEB was significantly more likely in patients classified with Forrest Ib (OR, 24.35; p<0.001), IIa (OR, 12.91; p<0.001), or IIb (OR, 8.31; p<0.001) ulcers compared with Forrest III ulcers. There was no statistically significant difference between the prophylactic hemostasis and non-hemostasis groups (Forrest Ib, p=0.938; IIa, p=0.438; IIb, p=0.397; IIc, p=0.773) during second-look endoscopy. CONCLUSIONS: The Forrest classification of artificial gastric ulcers during second-look endoscopy seems to be a useful tool for predicting delayed bleeding. However, routine prophylactic hemostasis during second-look endoscopy seemed to not be useful for preventing DPEB.

BACKGROUND/AIMS: We conducted a prospective, randomized, double-blinded, placebo-controlled trial to investigate the effect of hyoscine-N-butyl bromide during colonoscopy. METHODS: A total of 133 patients undergoing colonoscopy were randomized to receive either 20 mg of hyoscine-N-butyl bromide (n=70) or normal saline solution (n=63) via intramuscular injection as premedication. RESULTS: The mean cecal intubation time and withdrawal time in the hyoscine-N-butyl bromide group were significantly shorter than those of the control group (5.26+/-2.78 min vs. 6.74+/-4.89 min; p=0.032, 5.42+/-1.54 min vs. 6.18+/-2.54 min; p=0.038, each). The spasm grade in the hyoscine-N-butyl bromide group was significantly lower than that of the control group (p<0.001). No significant differences were found in the polyp detection rate (15.7% vs. 28.6%; p=0.073) and adenoma detection rate (10.0% vs. 15.9%; p=0.311). Difficulty of colonoscopy for the endoscopists and nurses (p=0.853; p=0.732), the patient's comfort (p=0.891) and the patient's willingness to repeat colonoscopy (85.7% vs. 82.5%; p=0.932) were also similar in both groups. CONCLUSIONS: Premedication with intramuscularly administered hyoscine-N-butyl bromide do not demonstrate any additional benefits except reducing the colonoscopy insertion time.

Lymphangioma is a benign vascular lesion that shows the characteristics of subepithelial tumor, which can proliferate in the lymphatic system. Only a few cases of multiple lymphangimas of the colon, the so called "colonic lymphanigomatosis", have been currently reported on the medical literature. Because lymphangioma is absolutely a benign tumor, it does not require any specific treatment, except for rare disease-related symptoms or complications such as anemia, intussusception and protein-losing enteropathy. Endoscopic resection for this tumor has sometimes been performed for both diagnostic and therapeutic purposes. We recently experienced a case of multiple colonic lymphangomas that arose in the ascending colon of a 46-year-old male patient and these lesions were found during performance of colonoscopy. The final diagnosis was confirmed by a pathologic examination of the specimen that was obtained via endoscopic resection. Follow-up colonoscopy at 1 year after the initial examination showed complete resolution of the previously noted lesions without any specific treatment. We report here on a very rare case of colonic lymphangiomatosis along with a brief review of the relevant literature.

Psoas abscesses are rare clinical entities complicating Crohn's disease (CD). However, psoas abscesses can cause poor outcomes because the diagnosis is frequently delayed due to the non-specific clinical features. Recently, we managed a case of a huge iliopsoas abscess in a 21-year-old man with a 4-year history of CD who presented with a limping gait and flexion contractures of the sacroiliac joint. Notably, the iliopsoas abscess developed during induction treatment with infliximab. The patient was successfully treated with antibiotics, surgical drainage, and a right hemicolectomy. Herein we present the case with a brief review of the literature.
