Background/Aims:
Restorative proctocolectomy (RPC) with ileal pouch-anal anastomosis and handsewn anastomosis for ulcerative colitis requires pulling down of the ileal pouch into the pelvis, which can be technically challenging. We examined risk factors for the pouch not reaching the anus.
Methods:
Clinical records of 62 consecutive patients who were scheduled to undergo RPC with handsewn anastomosis at the University of Tokyo Hospital during 1989–2019 were reviewed. Risk factors for non-reaching were analyzed in patients in whom hand sewing was abandoned for stapled anastomosis because of nonreaching. Risk factors for non-reaching in laparoscopic RPC were separately analyzed. Anatomical indicators obtained from presurgical computed tomography (CT) were also evaluated.
Results:
Thirty-seven of 62 cases underwent laparoscopic procedures. In 6 cases (9.7%), handsewn anastomosis was changed to stapled anastomosis because of non-reaching. Male sex and a laparoscopic approach were independent risk factors of non-reaching. Distance between the terminal of the superior mesenteric artery (SMA) ileal branch and the anus > 11 cm was a risk factor for non-reaching.
Conclusions
Laparoscopic RPC with handsewn anastomosis may limit extension and induction of the ileal pouch into the anus. Preoperative CT measurement from the terminal SMA to the anus may be useful for predicting non-reaching.

BACKGROUND/AIMS: Upper gastrointestinal symptoms are more frequent and severe in female than in male outpatients in Japan. This study compared the upper gastrointestinal symptoms between healthy male and female young adult volunteers using a questionnaire. METHODS: In total, 581 third-grade medical students at Saga Medical School aged 22 to 30 years underwent upper gastrointestinal endoscopy and completed a questionnaire (frequency scale for symptoms of gastroesophageal reflux disease) from 2007 to 2013. Of these 581 students, 298 who were negative for Helicobacter pylori infection and had no particular lesions on endoscopic examination were enrolled in the present evaluation. A symptom was defined as positive when the subject evaluated the frequency of the symptom as sometimes, often, or always. RESULTS: The subjects comprised of 163 males (average age, 23.7 years) and 135 females (average age, 23.1 years). Upper gastrointestinal symptoms were more frequent in the females (75 of 135, 55.6%) than males (69 of 163, 42.3%; P < 0.05), with a high score for 4 symptoms (bloated stomach, heavy feeling in the stomach after meals, subconscious rubbing of the chest with the hand, and feeling of fullness while eating meals). Of the 144 subjects (69 males and 75 females) who complained of these symptoms, the females complained of dysmotility symptoms more often than did the males, but this was not true for reflux symptoms. CONCLUSIONS: This study suggests that females develop upper gastrointestinal symptoms more frequently than do males among the young healthy Japanese population.

We report a case of type A acute aortic dissection in an elderly woman with immune thrombocytopenia (ITP) who underwent replacement of the ascending aorta and aortic arch and later required aortic root replacement for redissection of the aortic root one month after her initial surgery. She was an 86-year-old woman with severe mitral regurgitation, and surgery was contraindicated because of her age and ITP. In October 2014, the patient presented with back pain. Computed tomography confirmed the diagnosis of her condition as type A acute aortic dissection, and she was immediately transferred to our hospital. Because echocardiography showed severe aortic regurgitation, severe mitral regurgitation, and moderate tricuspid regurgitation, we performed replacement of the ascending aorta and aortic arch, mitral valve repair, and tricuspid annuloplasty. We used Bioglue to fuse the false lumen of the type A acute aortic dissection and used a Teflon felt sandwich for the proximal anastomosis technique. Respiratory support was discontinued 91 h after her first operation ; however, 30 days after surgery, she developed a to-and-fro murmur-a sign of the progression of heart failure. Echocardiography showed aggravation of aortic regurgitation, and computed tomography showed aortic root redissection ; therefore, 39 days after the initial surgery, we performed aortic root replacement. During the operation, we found the entry under the proximal anastomosis with an almost semicircle form at the right coronary cusp to the noncoronary cusp, and the dissection extended close to the right coronary artery ; thus, we performed bypass to the right coronary artery. Pathologic findings did not establish a causal association between the redissection and Bioglue, and we believed the fragility of the tissue and the selection of the surgical procedure to be the cause of redissection. The patient was transferred to another hospital when she was able to walk and eat, which was 121 days after her first operation. The patient required 50 units of platelet transfusion during her first and second operations, but her bleeding was easily controlled during surgery. She needed two procedures of pericardium drainage for pericardiac effusion and cardiac tamponade, which may relate to ITP. The diagnosis of redissection of the aortic root was made 30 days after the patient's first operation, on the basis of exacerbation of the to-and-fro murmur. Here, we emphasize the clinical importance of basic observations over time, such as auscultation, that are liable to be overlooked in the intensive care unit.

The patient was a 74-year-old woman who had undergone mitral valve replacement with a mechanical valve for rheumatic mitral valve stenosis at age 60. She was scheduled for aortic valve replacement for severe aortic stenosis. However, she had significantly worsening anemia before the operation. Capsule endoscopy showed angiodysplasia with bleeding in her small intestine, which was considered the cause of the anemia. Because of progressive anemia, we tried embolization under angiography. However, there was no evidence of extravasation. Neither melena nor exacerbation of anemia was observed, and she underwent aortic valve replacement. She was discharged on postoperative day 22 without gastrointestinal bleeding. Heyde syndrome is aortic valve stenosis associated with gastrointestinal bleeding induced by von Willebrand disease and angiodysplasia in small intestine. Molecular multimeric analysis of von Willebrand factor and the existence of angiodysplasia with hemorrhage of the digestive tract are important for definitive diagnosis. Capsule endoscopy, which is a general examination, is more useful for diagnosis than molecular multimeric analysis of von Willebrand factor. Aortic valve replacement is the only therapeutic option for Heyde syndrome. It is important to decide the appropriate timing of AVR with cardiopulmonary bypass.

Since late 2013 through March 2014, Japan experienced a rapid rise in measles cases. Here, we briefly report on the ongoing situation and share preliminarily findings, concerns and challenges and the public health actions needed over the coming months and years.
Measles is a notifiable disease in Japan based on nationwide case-based surveillance legally requiring physicians to report all clinically diagnosed and laboratory-confirmed cases within seven days, but preferably within 24 hours. After a large outbreak in 2007–2008 (more than 11 000 cases reported in 2008 alone) and a goal of elimination by April 2015, a catch-up programme using the bivalent measles-rubella (MR) vaccine was offered for grades seven and 12 (ages 12–13 and 17–18 years) from April 2008 through March 2013. During this period, there was an estimated 97% decline in measles notifications, and the cumulative number of reported cases has been steadily declining over the last five years (732 cases in 2009, 447 cases in 2010, 439 cases in 2011, 293 cases in 2012 and 232 cases in 2013). However, since late 2013 through March 2014, the country experienced a resurgence only a year after a large rubella outbreak.

A 31-year-old man fell into syncope caused by compression by a machine in his factory. He was taken to the nearest hospital at once for treatment. His chest X-ray seemed normal and his general condition improved. He received no medical treatment and was allowed to return home. Two days later, he went to the hospital for further investigation, and contrast-enhanced chest computed tomography (CT) was performed. Chest CT showed aortic dissection from the ascending aorta to the aortic arch. Therefore, he was admitted for bed rest with antihypertensive therapy. He was discharged on the 35th day after the accident. However, the diameter of the ascending aorta was found to have become dilated, and so he underwent ascending aorta and hemiarch replacement at our hospital. His postoperative course was uneventful, and he was discharged on the 16th postoperative day. We report a rare case of an acute aortic dissection caused by blunt chest trauma.

An 8 year-old boy had a cardiac murmur pointed out on day three after birth and was given a diagnosis of ventricular septal defect (VSD). He underwent VSD patch closure at two months after birth. He was also found the having Loeys-Dietz syndrome on the basis of mutation of TGFBR2 and physical examination at the age of 2 years. He had been followed up at pediatrics clinic of our hospital since then, and was hospitalized for a 46.5-mm extension of valsalva sinus diameter and moderate aortic insufficiency. The aortic valve was three-cusped and had no abnormality. We performed valve-sparing aortic root replacement. He was discharged on day 18 after the operation without any problems in the postoperative course. Use of an artificial heart valve for the surgery of the aortic root lesion in childhood will probably cause reoperation in the future and difficulty in Warfarin anticoagulation control. A careful decision is needed in the choice of an operation method. Valve-sparing aortic root replacement is a useful operation for patients without aortic valve abnormality.

A pseudoaneurysm of the thoracic aorta after cardiac surgery is a rare complication, but can be life-threatening when it is ruptured. The pseudoaneurysm itself presents no symptoms in many cases, or may be similar to an atherosclerotic aortic aneurysm. Therefore, it is usually found incidently during imaging studies. We encountered 3 cases of pseudoaneurysm of the thoracic aorta that developed during the long-term follow-up after congenital cardiac surgery. None of the patients experienced specific symptoms associated with the pseudoaneurysm, and were diagnosed by chest roentgenograms and computed tomography. Most patients who undergo surgery for congenital heart defects as adolescents are free from medical treatment, and do not regularly see a doctor after the surgery. It is important to consider the possibility of a pseudoaneurysm in patients having a history of cardiac surgery.
