Although not as common as foreign bodies in the upper gastrointestinal tract, rectal foreign body insertion is often encountered in emergency departments. The diverse types of rectal foreign bodies have led to various removal methods. When removing a foreign body, the first thing to consider is which method is the least invasive and safest for the patient. This paper reports the successful removal of a rectal foreign body from the rectum using the Valsalva maneuver without anesthesia in a patient.

Background: Many studies have reported the use of simethicone before colonoscopy removes bubbles. However, guidelines weakly recommend simethicone administration before colonoscopy. The present study aimed to confirm the advantages of taking simethicone and determine the appropriate time for taking simethicone. Methods: We randomly assigned patients to the following 5 groups according to the administration time: 4 groups were divided based on 2 parameters (the day before and on the day of colonoscopy and before and after bowel cleansing) and the remaining group was the control group. We compared bubble score (BS), number of simethicone solution irrigations when visually obscured, satisfaction score of the endoscopist, insertion time. Results: A total of 204 patients were included in the study. There was a difference in BS according to the timing of simethicone administration ( P < .001). The group taking simethicone on the day of the test had a better BS than the group taking simethicone the day before ( P < .001). The group taking simethicone on the previous day had a better BS than the control group ( P = .001). In the group of taking simethicone on the examination day, the number of irrigations was lower, and satisfaction with the inspector was higher than group of taking simethicone on previous day and control group (both P < .001). The insertion time showed a non-significantly decreasing trend ( P = .417). Conclusion: Administering simethicone reduced bubbles and facilitated effective colonoscopy, especially when administrating it on the day of examination. It needs to be administered on the day of the examination regardless of bowel preparation.

Eosinophilic esophagitis (EoE) is an immune or antigen-mediated chronic inflammatory esophageal disorder that is relatively rare in Asian countries. The main symptoms of EoE are dysphagia and food impaction. Although chest pain is a symptom of EoE, it is also a symptom of coronary heart disease. This paper reports a case of EoE with angina pectoris in a 45-year-old male who was referred to the authors' hospital for chest pain. He was diagnosed with angina pectoris because of mild stenosis in the left coronary artery on coronary angiography. On the other hand, the symptoms did not improve with angina medication therapy. Therefore, he underwent a chest CT scan, which revealed esophageal thickening. Esophagogastroduodenoscopy was performed. His endoscopic findings showed linear furrows with edema, and >90 eosinophils existed per high-power field on the histology findings. He was diagnosed with EoE. Through additional examinations, he was also diagnosed with asthma. The patient was treated with a proton pump inhibitor and a fluticasone inhaler. His symptoms and abnormal endoscopic findings disappeared after eight weeks of treatment. This case shows that physicians should consider the possibility of the symptoms for EoE when unexplained chest pain persists.

Transarterial chemoembolization (TACE) is a common treatment for unresectable hepatocellular carcinoma (HCC). The most common complications after TACE are non-specific symptoms called post-embolization syndrome, such as abdominal pain or fever. Rare complications, such as liver failure, liver abscess, sepsis, pulmonary embolism, cholecystitis, can also occur. On the other hand, gallbladder perforation is quite rare. This paper reports a case of gallbladder perforation following TACE. A 76-year-old male with a single 9-cm-sized HCC underwent TACE. Five days after TACE, he developed persistent right upper quadrant pain and ileus. An abdomen CT scan confirmed gallbladder perforation with bile in the right paracolic gutter and pelvic cavity. Percutaneous transhepatic gallbladder drainage was performed with the intravenous administration of antibiotics. After 1 month, the patient underwent right hemihepatectomy and cholecystectomy. Physicians should consider the possibility of gallbladder perforation, which is a rare complication after TACE, when unexplained abdominal pain persists.
