The number of surgical treatments for acute aortic dissection in octogenarians is increasing. They should return to their daily life as soon as possible after the operation without any complications. Some literature reported that minimally invasive cardiac surgery (MICS) helps quick recovery for the patients. We report a case of minimally invasive ascending aorta replacement for Stanford type A chronic thrombosed aortic dissection in an octogenarian to help quick recovery. An 81-year-old man was admitted in our hospital suffering from chest and back pain. Enhanced CT scan showed Stanford type A acute thrombosed aortic dissection. The diameter of ascending aorta was 45 mm and the diameter of false lumen was 7 mm. Therefore we decided on medical treatment for this patient according to the guideline. After four weeks medical treatment, ascending aorta was dilated to 49 mm and the false lumen also expanded to 9 mm. He underwent minimally invasive ascending aorta replacement to help quick recovery considering his age. He was discharged 11 days postoperatively without any complications. MICS offers a better cosmetic result, less blood loss, less pain, better respiratory function and quick recovery. Thus, minimally invasive operation for the elderly is also very satisfactory.

Objective:
Previously, we reported that insulinoma-associated protein 1 (INSM1) immunohistochemistry (IHC) showed high sensitivity for neuroendocrine carcinoma of the uterine cervix and was an effective method for histopathological diagnosis, but that its specificity remained to be verified. Therefore, the aim was to verify the specificity of INSM1 IHC for a large number of non-neuroendocrine neoplasia (NEN) of the cervix.
Methods:
RNA sequences were performed for cell lines of small cell carcinoma (TCYIK), squamous cell carcinoma (SiHa), and adenocarcinoma (HeLa). A total of 104 cases of formalin-fixed and paraffin-embedded specimens, 16 cases of cervical NEN and 88 cases of cervical non-NEN, were evaluated immunohistochemically for conventional neuroendocrine markers and INSM1. All processes without antigen retrieval were performed by an automated IHC system.
Results:
The transcripts per million levels of INSM1 in RNA sequences were 1505 in TCYIK, 0 in SiHa, and HeLa. INSM1 immunoreactivity was shown only in the TCYIK. Immunohistochemical results showed that 15 cases of cervical NEN showed positive for INSM1; the positivity score of the tumor cell population and the stain strength for INSM1 were high. Two of the 88 cases of cervical non-NENs were positive for INSM1 in one case each of typical adenocarcinoma and squamous cell carcinoma. The sensitivity of INSM1 for cervical NEN was 94%; specificity, 98%; the positive predictive value, 88%; and the negative predictive value, 99%.
Conclusion
INSM1 is an adjunctive diagnostic method with excellent specificity and sensitivity for diagnosing cervical NEN. Higher specificity can be obtained if morphological evaluation is also performed.

A 47-year-old man was admitted to our hospital complaining of chest and back pain. Enhanced CT scan revealed Stanford type A acute aortic dissection. The celiac artery (CA) was not enhanced and the superior mesenteric artery (SMA) appeared on the delayed phase. There was a small amount of pericardial effusion. Blood gas analysis showed metabolic acidosis. To treat mesenteric malperfusion, we initially performed thoracic endovascular aortic repair (TEVAR) by the PETTICOAT technique and stenting to CA and SMA. The acidosis gradually normalized after TEVAR. We then performed surgical central repair (total arch replacement). He temporarily showed paraplegia after the operation but soon recovered by treatment for spinal ischemia. He was discharged 68 days post operatively without any complication. Surgical central repair is not always effective for treating organ ischemia, so endovascular repair before surgical operation is sometimes taken into consideration.

Background/Aims:
The aim of this study was to evaluate the safety of sedation with propofol as an alternative to benzodiazepine drugs in outpatient endoscopy.
Methods:
In this prospective study, examinees who underwent outpatient endoscopy under propofol sedation and submitted a nextday questionnaire with providing informed consent were evaluated. Periprocedural acute responses, late adverse events within 24 hours, and examinee satisfaction were evaluated.
Results:
Among the 4,122 patients who received propofol in the 17,978 outpatient-based endoscopic examinations performed between November 2016 and March 2018, 2,305 eligible examinees (esophagogastroduodenoscopy for 1,340, endoscopic ultrasonography for 945, and total colonoscopy for 20) were enrolled, and their responses to a questionnaire were analyzed. The mean propofol dose was 69.6±24.4 mg (range, 20–200 mg). Diazepam, midazolam, and/or pentazocine in combination with propofol was administered to 146 examinees. Mild oxygen desaturation was observed in 59 examinees (2.6%); and mild bradycardia, in 2 (0.09%). Other severe reactions or late events did not occur. After eliminating 181 invalid responses, 97.7% (2,065/2,124) of the patients desired propofol sedation in future examinations.
Conclusions
Propofol sedation was found to be safe—without severe adverse events or accidents—for outpatient endoscopy on the basis of the patients’ next-day self-evaluation. Given the high satisfaction level, propofol sedation might be an ideal tool for painless endoscopic screening.

The Japanese Society of Hepato-Biliary-Pancreatic Surgery launched the clinical practice guidelines for the management of biliary tract cancers (cholangiocarcinoma, gallbladder cancer, and ampullary cancer) in 2007, then published the 2nd version in 2014. In this 3rd version, clinical questions (CQs) were proposed on six topics. The recommendation, grade for recommendation, and statement for each CQ were discussed and finalized by an evidence-based approach. Recommendations were graded as grade 1 (strong) or grade 2 (weak) according to the concepts of the grading of recommendations assessment, development, and evaluation system. The 31 CQs covered the six topics: (1) prophylactic treatment, (2) diagnosis, (3) biliary drainage, (4) surgical treatment, (5) chemotherapy, and (6) radiation therapy. In the 31 CQs, 14 recommendations were rated strong and 14 recommendations weak. The remaining three CQs had no recommendation. Each CQ includes a statement of how the recommendations were graded. This latest guideline provides recommendations for important clinical aspects based on evidence. Future collaboration with the cancer registry will be key for assessing the guidelines and establishing new evidence.

A 71-year-old woman underwent repair of a ventricular septal perforation due to myocardial infarction by the extended sandwich patch technique 5 years ago. She was discharged from the hospital without complications. During the follow-up period, a ventricular apical aneurysm was found on contrast-enhanced computed tomography and transthoracic echocardiography. Since the aneurysm had enlarged gradually and a thrombus was found in it, repairing surgery was indicated. The patient was initiated on cardiopulmonary bypass after dissection of the adhesions of the previous surgery, and a longitudinal incision was made on the left side of the left anterior descending artery under cardiac arrest to remove the aneurysm. A large amount of thrombus was found inside the aneurysm. The thrombus was removed, Dor surgery was performed with a circular Hemashield patch. Reports of ventricular apical aneurysm after myocardial infarction in a remote period are rare. It is necessary to perform surgical intervention as soon as possible to prevent free wall rupture as well as cerebral infarction.
