We report two cases of Schloffer tumor that required resection after radical colon cancer surgery because of suspected lymph node recurrence on contrast‐enhanced (CE) CT and 18F‐FDG‐PET/CT. Case1 is a 69‐year‐old man with sigmoid colon cancer pStage IIA, and case2 is a 61‐year‐old man with descending colon cancer pStage IIIB. [ABSTRACT FROM AUTHOR]

Traumatic asphyxia is a crush injury of the chest characterized by facial edema, cyanosis, conjunctival hemorrhage, and petechiae on the face and chest. The prognosis depends on the duration of chest compression and early cardiopulmonary resuscitation after cardiopulmonary arrest. Here we report a case of full recovery from cardiopulmonary arrest caused by traumatic asphyxia. The chest of a 56-year-old man was compressed by a machine while working. Immediately, his colleague started cardiopulmonary resuscitation, which was successful. When he was admitted to our hospital, his consciousness level was E1V2M2(Glasgow coma scale). Our treatment included therapeutic hypothermia, the duration of which was 24 hours at 34 °C. Rewarming his body to 36 °C took place over 48 hours. Thereafter, he recovered completely and was discharged on the 12th hospital day without neurologic sequela. Therapeutic hypothermia was possibly effective in this case.

A male patient in his thirties was scheduled to undergo adenotonsillectomy due to dyspnea from bilateral tonsillar hypertrophy. He was morbidly obese (body mass index 56 kg x m(-2)) with severe obstructive sleep apnea syndrome (OSAS), and thus was evaluated with extreme risk for difficult ventilation and intubation. We planned awake intubation via video-assisted laryngoscopy and fiberoptic bronchoscopy under dexmedetomidine sedation, and the intubation was successfully performed. After adenotonsillectomy, upper airway obstruction due to hemorrhage and oropharyngeal swelling can be life-threatening requiring emergent airway management. Thus for postoperative airway management, due to the possibility of "cannot intubate, cannot ventilate" (CICV) and presumed difficult tracheotomy, we scheduled to perform tracheotomy during adenotonsillectomy, right after anesthetic induction and awake intubation. On postoperative day 1, he started walking with no need of sedative drugs. On day 4, after confirmation of minimal oropharyngeal swelling, tracheal cannulae was removed, and no further complications were observed in his postoperative course. We conclude that careful preoperative evaluation of the airway, retention of spontaneous breathing via awake intubation, and preventive tracheotomy for postoperative airway management are important points in perioperative management of a morbidly obese patient with severe obstructive sleep apnea syndrome.

Preanesthetic evaluation is essential for the perioperative period. We report 2 preoperative patients with benign disease, whose preoperative chest radiography revealed intrathoracic malignant tumors. Case 1: A woman in her eighties with vascular necrosis of the femoral head was scheduled for bipolar hip arthroplasty under general anesthesia. On preanesthetic evaluation, widened mediastinum was detected on preoperative chest radiography. Instead of the scheduled operation, she underwent thoracoscopic surgery under general and epidural anesthesia. She was diagnosed with malignant thymoma. Case 2: A woman in her thirties with bilateral oviduct obstruction was scheduled for laparoscopic surgery. On preanesthetic evaluation, right middle lung lesion was detected. She underwent thoracoscopic biopsy under general and epidural anesthesia, and was diagnosed with malignant lymphoma. The result of preanesthetic chest radiography is reported to change the perioperative treatment only in 0.1%; our cases indicate the importance of preanesthetic evaluation of chest radiography in detecting possible underlying disease in the preoperative patient.
