A Case of Intramural Hematoma of the Esophagus Mimicking Acute Coronary Syndrome / 대한소화기학회지

Intramural hematoma of the esophagus is a rare condition that can be spontaneous or secondary to trauma, toxic ingestion, or intervention. If it is the spontaneous type, it usually presents initially with epigastric pain, hematemesis or dysphagia. We present a case of intramural hematoma of the esophagus mimicking acute coronary syndrome. A 63-year-old man presented with severe acute chest pain. He has four coronary stents that were inserted five years ago, from a different hospital, and is on dual antiplatelet agents. Coronary angiography was performed immediately under the suspicion of acute coronary syndrome, and we found that there was no obvious clogging of the coronary arteries. Next, chest computed tomography was performed due to suspected aortic dissection, and the result was also negative. Four days later, endoscopy was performed and intramural hematoma covered with large ulcers was diagnosed.

A Case of Midazolam Anaphylaxis

Midazolam is a type of anesthetic agent frequently used for conscious sedation during a variety of medical procedures. Anaphylactic reactions to midazolam are rarely reported. However, we observed a case of midazolam hypersensitivity in which emergency measures were required to ensure patient recovery after administration of midazolam as a sedative. The occurrence of the anaphylactic reaction to midazolam was confirmed by elevated serum tryptase levels. The current case report presents a discussion of our findings.

Perforation of Gastrointestinal Stromal Tumor in Small Bowel on an Elderly Patient Presenting Acute Abdominal Pain

Acute abdominal pain as a common complaint in elderly patients may differ from that in younger patients. In elderly patients, the diagnostic accuracy of acute abdominal pain is lower compared to that in younger patients. On the other hand, the mortality in elderly patients with acute abdominal pain is far higher than that in the younger patients. Therefore, early and correct diagnosis of acute abdominal pain for the elderly patients could significantly influence the outcome. In this report, we describe a case of a 84-year-old man with a ruptured small bowel gastrointestinal stromal tumor who presented at the Emergency Department with acute abdominal pain. Laparotomy was performed because perforation of a tumor in the jejunum was found by computed tomography. Diagnosis was confirmed by histopathology and immunohistochemistry. Therefore, small bowel disease should be considered when exploring the cause of acute abdominal pain in elderly patients.

Endoscopic Clip Closure of Duodenal Perforation Caused by Percutaneous Drainage Procedure

Acute cholecystitis is a disease commonly treated in health care institutions. Cholecystectomy is the standard treatment for acute cholecystitis, and emergent laparoscopic cholecystectomy is acceptable as an effective and safe treatment modality. One of the complications after laparoscopic cholecystectomy is intra-abdominal abscess. The standard treatment for postoperative intra-abdominal abscess is percutaneus transhepatic drainage and use of antibiotics. However, duodenal perforation can occur during insertion of the pigtail catheter for drainage. Operation is the treatment of choice for iatrogenic duodenal perforations. Recent reports describe nonsurgical treatments for small gastrointestinal perforation with localized peritonitis and suggest that endoclipping may be appropriate in the management of a well selected group of patients with iatrogenic perforation. We describe a case of duodenal perforation due to pigtail catheter insertion for percutaneous transhepatic drainge that was succesfully treated by using endoclips.

Negative Pressure Pulmonary Edema Together with Pneumopericardium after General Anesthesia / 대한내과학회지

Negative pressure pulmonary edema is an uncommon complication related to general anesthesia. Its main pathophysiology is excessive negative intrathoracic pressure that is caused by an acute upper airway obstruction. Pneumopericardium, the presence of air within the pericardial sac, is another rare condition. The common pathophysiology of pneumopericardium, except for that caused by blunt or penetrating trauma, is barotrauma-induced alveolar rupture caused by positive intrathoracic pressure. Here, we report the case of a 61-year old female patient with negative pulmonary edema and pneumopericardium after general anesthesia. She recovered after conservative management.

Primary Pure Squamous Cell Carcinoma Originating from the Stomach

Primary gastric squamous cell carcinoma represents a rare entity. Up to date, only seven cases have been reported in Korea. This paper reports a case of a 51-year-old male patient whose stomach cancer was diagnosed during general routine check-up. Upper gastrointestinal endoscopy showed a large ulcero-fungating mass on the body of the stomach. Histological examination of biopsy confirmed squamous cell carcinoma. An extended total gastrectomy including splenectomy and segmental resection of the large bowel was conducted. Postoperative adjuvant chemotherapy with capecitabine and oxaliplatin was followed. The patient has been following up the out patient's clinic after discharge.
