Nasogastric tube syndrome: A case of vocal cord paralysis due to a nasogastric tube.

Insertion of a nasogastric tube is one of the most common methods of administering nutrition, but can cause vocal cord paralysis.

Cardiopulmonary arrest caused by nafamostat mesylate during hemodialysis.

Dialysis-related adverse reactions can be serious and difficult to predict. In our case, nafamostat mesylate (NM) was thought to be the cause of cardiopulmonary arrest (CPA) due to NM-induced anaphylaxis but was not reflected in the allergy tests. Rare but life-threatening drawbacks occur immediately after hemodialysis initiation.

Isolated tricuspid valve infective endocarditis with multiple septic pulmonary emboli in a patient with atopic dermatitis.

Multiple lung nodules in atopic dermatitis patients may reflect infective endocarditis. Our case underlines the importance of potentially severe infections due to staphylococci associated with atopic dermatitis.

Enlargement of Intrathoracic Goiter with Unilateral Phrenic Nerve Paralysis Leading to Cardiopulmonary Arrest.

As an intrathoracic goiter expands, it causes airway stenosis and phrenic nerve paralysis, and slight respiratory stimuli can trigger sudden life-threatening hypoventilation. A 78-year-old obese woman with a large intrathoracic goiter was found unconscious with agonal breathing in her room early in the morning. Cardiopulmonary resuscitation restored spontaneous circulation. She underwent surgical removal of the goiter; however, she required long-term mechanical ventilation because of atelectasis due to phrenic nerve paralysis. In patients with large intrathoracic goiters, difficulty breathing on exertion and diaphragm elevation on chest X-ray may be significant findings predicting future respiratory failure.

Delayed diagnosis of traumatic ventricular septal perforation in penetrating chest injury: hematoma formation in the ventricular septum in CT suggests perforation.

BACKGROUND: Ventricular septal perforation (VSP) can be caused by a penetrating cardiac injury. Diagnosis of VSP tends to be delayed because a shunt might not be detected by color flow Doppler at an early stage following injury. CASE PRESENTATION: A 60-year-old man with depression was admitted to the emergency center after a knife injury in the chest. A focused assessment with sonography for trauma revealed cardiac tamponade. Shortly after an open cardiac massage and a pericardiotomy, his spontaneous circulation returned. At a later stage, follow-up computed tomography, echocardiography, and left ventriculography showed traumatic ventricular septal perforation. Conservative therapy was chosen because the pulmonary blood flow/systemic blood flow ratio was 1.42. CONCLUSION: The initial contrast computed tomography shows a septal hematoma. Its presence could be perceived as a perforation site in the interventricular septum.

Surgically Diagnosed Primary Hepatic Angiosarcoma.

Primary hepatic angiosarcoma is a rare tumor originating from endothelial cells in the liver and accounts for approximately 1% of all hepatic malignant tumors. It is difficult to diagnose due to the lack of specific symptoms or tumor markers. No effective treatment exists, but complete surgical resection may achieve a good outcome. Since most primary hepatic angiosarcomas are already at an advanced stage at diagnosis, few reports describe tumors smaller than 2 cm. We report a case of surgery for a 1.7-cm sized primary hepatic angiosarcoma. Further studies are required to improve the preoperative diagnosis of primary hepatic angiosarcoma.

[A Case of Rectal Stenosis For Gastric Cancer Recurrence Effectively Treated with a Colonic Stent].

A man in his 70s underwent distal gastrectomy and D1 dissection with Roux-en-Y reconstruction in March 2009 for advanced gastric cancer with peritoneal metastasis. He was diagnosed with signet-ring cell carcinoma, Stage Ⅳ(T4a, N3a, H0, P1, CY1, M1) and R2. Seventeen cycles of S-1 plus CDDP were administered from April 2009 to December 2010 and 19 cycles of S-1 monotherapy were administered from January 2011 to March 2014. He developed peritoneal recurrence with serum tumor marker elevation in May 2014. Stenosis of the common bile duct, hydronephrosis, and rectal stenosis in Ra-Rs was observed in June 2014. A bile duct stent and a double J catheter was inserted. A colonic stent (NitiTM, 22 mm×6 cm) was also inserted. He could eat after the surgery and was discharged from the hospital. We suggest that a colonic stent is an effective treatment for colon stenosis due to peritoneal metastasis from gastric cancer.

[Gastroduodenal stent placement in gastric cancer patients with pyloric stenosis].

We examined 11 gastric cancer patients undergoing gastroduodenal stent placement for the treatment of gastric outlet obstruction at our hospital, and assessed the significance and problems associated with stenting. None of the patients exhibited any complications associated with stenting, and the median post-stenting fasting period was 3 days(range, 1-7 days). Oral intake improved significantly in all the patients; in patients with nasogastric tubes, the tubes were removed after stenting. However, in patients with peritoneal dissemination, oral intake alone was not sufficient, and additional parenteral nutrition was required. In conclusion, gastroduodenal stenting is believed to be useful for palliative care in gastric cancer patients with pyloric stenosis.
