This report describes 5 patients in whom extensive graft replacement was performed using a combination of median sternotomy with antero- or postero-lateral thoracotomy: 3 of them received replacement from the ascending to the descending thoracic aorta through the transverse aortic arch, and 2 of them received replacement from the transverse aortic arch to the descending thoracic aorta. Four of the 5 patients had catastrophic pulmonary bleeding during surgery and died immediately after the surgery. Histological investigations on 3 of the 5 patients revealed the presence of bleeding in bilateral alveola; edema in the pulmonary parenchymal tissues; and heavy bleeding extensively in the lung which was especially intensive in the pulmonary hilum and caused necrosis of that region in one case. We presume that long periods of total heparinization (extracorporeal circulation time>240min) performed during lateral thoracotomy, were the most important cause of the pulmonary bleeding. Other factors that could cause pulmonary bleeding are (i) avoidance of use of a double lumen endotracheal tube, (ii) pulmonary congestion due to heart failure during surgery, and (iii) pulmonary injury caused by surgical manipulation. We therefore consider that extensive graft replacement of the thoracic aorta through lateral thoracotomy using a pump-oxygenator, is associated with a high risk of pulmonary bleeding when it takes longer than 240min, and it is essential to perform the graft replacement in the possible shortest time.

This study aimed to clarify whether a regional palliative care intervention program, the OPTIM project, increased home hospice utilization, and explore the potential association between the home hospice utilization and the hospital staff's perceptions on home care. A questionnaire survey was conducted involving 154 physicians and 469 nurses. The rate of patients who made the transition to home-based care increased 967% in A Hospital, 295% in B Hospital, and 221% in C Hospital in 2010 compared to 2007, which was assumed to be 100. Staff of a hospital where many patients made the transition to home-based care were more likely to agree with the following statements concerning home care perspectives: “I started to consider that even cancer patients can be treated at home until the last moment of their life”, “I usually ask patients whether they wish to receive home-based care”, “We decided on coping strategies for sudden changes in the course of disease and a place to contact in advance”, and “I started to simplify treatment procedures, such as prescriptions during hospitalization for patients and their families to prepare for home-based care“.

SUMMARY OF EVENT: Pneumoderma, mediastinal emphysema, and bilateral pneumothorax were developed in the patient who had undergone transesophageal endoscopic ultrasonography-guided rendezvous technique. Chest drainage was performed immediately. TEACHING POINT: Transesophageal approach carries the potential risks of severe complications such as mediastinal emphysema, mediastinitis, and pneumothorax. To prevent puncturing through the esophagus, clipping the esophagogastric junction using a forward-viewing scope before procedure is very useful. In cases of inadvertent transesophageal puncture, devices other than the needle should not be passed through the site.

Background/Aims:
The adenoma detection rate (ADR) of screening colonoscopies performed by trainees is often lower than that of colonoscopies performed by experts. The effcacy of cap-assisted colonoscopy (CAC) in adenoma detection is well documented, especially that of CACs performed by trainees. Endocuff, a new endoscopic cap, is reportedly useful for adenoma detection; however, no trials have compared the effcacy of Endocuff-assisted colonoscopy (EAC) and CAC conducted by trainees. Therefore, the present study retrospectively compared the effcacy between EAC and CAC in trainees.
Methods:
This was a single-center, retrospective study involving 305 patients who underwent either EAC or CAC performed by three trainees between January and December 2018. We evaluated the ADR, mean number of adenomas detected per patient (MAP), cecal intubation rate, cecal intubation time, and occurrence of complications between the EAC and CAC groups.
Results:
The ADR was significantly higher in the EAC group than in the CAC group (54.3% vs. 37.3%, p=0.019), as was the MAP (1.36 vs. 0.74, p=0.003). No significant differences were found between the groups with respect to the cecal intubation rate or cecal intubation time. No major complications occurred in either group.
Conclusions
Our results suggest that EAC exhibits increased ADR and MAP compared to CAC when performed by trainees.

SUMMARY OF EVENT: Bacterial, mycotic peritonitis and Candida fungemia developed in a patient with moderate ascites who had undergone endoscopic ultrasound-guided biliary drainage (EUS-BD). Antibiotics and antifungal agent were administered and ascites drainage was performed. Although the infection improved, the patient's general condition gradually deteriorated due to aggravation of the primary cancer and he died. TEACHING POINT: This is the first report to describe infectious peritonitis after EUS-BD. Ascites carries the potential risk of severe complications. As such, in patients with ascites, endoscopic retrograde cholangiopancreatography (ERCP) is typically preferred over EUS-BD or percutaneous drainage to prevent bile leakage. However, ERCP may not be possible in some patients with tumor invasion of the duodenum or with surgically altered anatomy. Thus, in patients with ascites who require EUS-BD, we recommend inserting the drainage tube percutaneously and draining the ascites before and after the intervention in order to prevent severe infection.

A 50-year-old man was admitted to our hospital due to chest pain. He had a history of chronic pancreatitis associated with a pancreatic pseudocyst. Coronary angiography revealed stenotic lesions in left main trunk and right coronary artery coronary artery bypass grafting (RITA-LAD, LITA-OM, SVG-#4PD) were performed. The postoperative course was uneventful without any complications, and he was discharged on the 9th day after surgery. A week later, fatigue and dyspnea appeared. Echocardiography showed a large mount of pericardial fluid and echo-guided pericardiocentesis was performed. One week after the procedure the pericardial fluid reaccumulated. Pericardial drainage resulted in continuous drainage of pericardial fluid. A 7 French plastic stent was placed in the pancreatic pseudocyst, which decompressed the pancreatic pseudocyst, which led to the disappearance of pericardial effusion accumulation. The possible relation between a recurrent pericardial fluid accumulation and a pancreatic pseudocyst was suspected.

An 82-year-old woman was transferred to our hospital due to an abrupt back pain. She exhibited a cardiac tamponade and her CT angiography revealed Stanford type-A acute aortic dissection without abdominal extension. Emergent surgery for partial arch replacement was performed. After a few days of stable postoperative course, she suffered 38 degrees fever with an elevated inflammatory response and complained of a slight abdominal pain. Her CT scan revealed an intra-abdominal abscess with a small intestine necrosis. Emergent surgery for partial small intestine resection was performed. Her postoperative course was stable and she was discharged to a rehabilitation hospital 52 days after the first operation.

Anti-inflammatory therapy is generally considered to be prior to surgery for Takayasu disease to achieve better outcomes. We report two Takayasu arteritis patients with thoracic aneurysm. Case 1 was a 19-year-old woman who presented acute trachyphonia for one month. CT revealed aortic arch aneurysm of which maximal diameter was 64 mm with partial cystic protrusion. We performed urgent total arch replacement before anti-inflammation therapy was induced. Postoperative course was uneventful and the patient discharged on steroid therapy. Case 2 was a 35-year-old woman who complained chest pain for two weeks. CT revealed a Valsalva aneurysm with maximal diameter 54 mm and the aortic wall of the arch including its branches was surrounded by thick low density area. As the FDG-PET confirmed inflammatory arteritis, initial steroid therapy was planned. However, one day before admission, the patient presented acute aortic dissection and did not respond to any resuscitation. We conclude that the right time of surgery or the initial induction of anti-inflammatory therapy for anuerysmal dilation by Takayasu arteritis is to be determined based not only on the inflammation level but also on aneurysmal size and the patient's severity of complaints.

Today, syphilitic aortic aneurysm is rarely diagnosed due to widespread use of penicillin for early syphilis. Large aneurysms can be symptomatic by compressing on adjacent organs. We report a case of a huge syphilitic aneurysm of the thoracic aorta complicated with airway obstruction and superior vena cava syndrome. A 62-year-old man presented with acute severe dyspnea and distention of superficial veins. Contrast-enhanced computed tomography revealed an aneurysm of the ascending aorta extending to the transverse arch the diameter of which was 90 mm. The aneurysm compressed the bilateral main bronchi and superior vena cava. We performed an emergency operation because respiratory failure persisted despite the support of a ventilator. Since the aneurysm eroded the sternum, median sternotomy was performed under hypothermic circulatory arrest. Dissecting the aneurysm was complicated due to dense adhesion. Ascending aorta and partial arch replacement with reconstruction of the brachiocephalic trunk was successfully performed with antegrade cerebral perfusion. Postoperative computed tomography demonstrated that compression of the bilateral main bronchi was released. The result of preoperative syphilitic serologic test was strongly positive, and pathological findings of the aneurysm wall specimen was compatible with syphilitic aneurysm. Following treatment with benzyl penicillin for 14 days, the patient was discharged on the 19th postoperative day without specific complications.

Surgical stress is closely associated with the activity of the thyroid hormone. Although many patients undergoing cardiac surgery revealed markedly low triiodothyronine (T3), few patients showed symptomatic hypothyroidism. This condition is generally recognized as “non thyroidal illness (NTI) ” which is characterized by a low T3 level, despite the normal function of hypothalamus-pituitary-thyroid system. NTI is generally considered as one of the biological defense mechanisms rather than a pathological condition, eliminating the requirement of medical intervention. Even if low T3 is observed in blood biochemical examination after open heart surgery, a cautious interpretation is required. We report an elderly case presenting severe fatigue and mild disorientation accompanied by significantly low thyroid hormone after aortic valve replacement. The morbidity was remarkably improved with medical treatment, suggesting hypothyroidism after cardiac surgery.
