The patient was a 63-years-old female with early gastric cancer in her upper stomach. Widely spreading on the mucous membrane, the cancer was too big to remove by endoscopical mucosal resection, although she wanted minimal invasive treatment. Therefore, we adopted total gastrectomy with hand-assisted laparoscopic surgery (HALS) after obtaining “informed consent” from her. Five small skin-incisions were necessary to perform it-one 7cm' for hand-port and four 1.2cm' for trocars.
The dissection was started from greater omentum and proceeded counterclockwise to remove primary lymphnodes. The abdominal esophagus and the duodenum were devided with a single or double application of Endo GIA stapler (linear stapler). All these steps were accomplished safely and securely with the effective support of the left hand of the operator. After extraction of the whole stomach through the 7cm-incision, Roux-en Y reconstruction was performed laparoscopically (esophago-jejunostomy) followed by hand sewing through the 7cm-incision (jejuno-jejunostomy). The anvil of 21mm circular stapler (EEA) was inserted orally in order to anastomose the esophagus to the jejunum. The patient had acceptable results intra-operatively as well as postoperatively by HALS total gastrectomy, which had been considered to be very hard to perform up to present time.

Methods:
Nineteen volunteers (16 men, three women) lifted a 60-kg doll from a seated position to a standing position. The first transfer was performed without the HAL for Care Support, and the second was performed with the HAL for Care Support assistive robot. We evaluated transfer performance, the visual analog scale (VAS) score for lumbar fatigue, and electromyogram analyses of the trunk and hip.
Results:
Four participants (two men, two women) succeeded with the HAL for Care Support even though they were unable to perform the task without it. The mean lumbar fatigue VAS score for all participants without the HAL for Care Support was 62 mm, while that with it was 43 mm. With lumbar assistance from the HAL for Care Support, subjective lumbar fatigue during the transfer decreased significantly. A power analysis indicated adequate statistical power to detect a difference in the VAS score for lumbar fatigue (0.99). The activity of the left gluteus maximus alone increased significantly during transfers with the HAL for Care Support. No adverse events occurred during use of the HAL for Care Support for transfers.
Conclusions
The HAL for Care Support was able to reduce lumbar load in a simulated patient transfer.

Background/Aims:
Bispectral index (BIS) monitors process and display electroencephalographic data are used to assess the depth of anesthesia. This study retrospectively evaluated the usefulness of BIS monitoring during endoscopic ultrasonography (EUS).
Methods:
This study included 725 consecutive patients who underwent EUS under sedation with propofol. BIS monitoring was used in 364 patients and was not used in 361. The following parameters were evaluated: (1) median dose of propofol; (2) respiratory and circulatory depression; (3) occurrence of body movements; (4) awakening score >8 at the time; and (5) awakening score 2 hours after leaving the endoscopy room.
Results:
The BIS group received a significantly lower median dose of propofol than the non-BIS group (159.2 mg vs. 167.5 mg; p=0.015) in all age groups. For patients aged ≥75 years, the reduction in heart rate was significantly lower in the BIS group than in the non-BIS group (1.2% vs. 9.1%; p=0.023). Moreover, the occurrence of body movements was markedly lower in the BIS group than in the non-BIS group (8.5% vs. 39.4%; p<0.001).
Conclusions
During EUS examination, BIS monitoring is useful for maintaining a constant depth of anesthesia, especially in patients 75 years of age or older.

A 68-year-old woman had unstable angina pectoris with asymptomatic right internal carotid artery and right middle cerebral artery occlusion with impaired cerebral perfusion reserve. The cardiology, cardiovascular surgery, anesthesiology, and neurosurgery departments discussed the treatment plan. We simultaneously performed superficial temporal artery-middle cerebral artery anastomosis and coronary artery bypass grafting to reduce the likelihood of perioperative ischemic stroke. Fortunately, neither cerebral ischemia nor myocardial ischemia occurred. Simultaneous superficial temporal artery-middle cerebral artery anastomosis and coronary artery bypass grafting can be a therapeutic option for patients with unstable angina and impaired cerebral perfusion reserve. However, the risk of bleeding associated with anticoagulation during coronary artery bypass grafting cannot be ignored.

Background:Capecitabine and irinotecan combination therapy (XELIRI) has been examined at various dose levels to treat metastatic colorectal cancer (mCRC). Recently, in the Association of Medical Oncology of the German Cancer Society (AIO) 0604 trial, tri?weekly XELIRI plus bevacizumab, with reduced doses of irinotecan (200mg/m2 on day 1) and capecitabine (1600mg/m2 on days 1–14), repeated every 3weeks, has shown favorable tolerability and effcacy which were comparable to those of capecitabine and oxaliplatin (XELOX) plus bevacizumab. The doses of capecit?abine and irinotecan in the AIO trial are considered optimal. In a phase I/II study, XELIRI plus bevacizumab (BIX) as second?line chemotherapy was well tolerated and had promising effcacy in Japanese patients. Methods:The Asian XELIRI ProjecT (AXEPT) is an East Asian collaborative, open?labelled, randomized, phase III clinical trial which was designed to demonstrate the non?inferiority of XELIRI with or without bevacizumab versus standard FOLFIRI (5?lfuorouracil, leucovorin, and irinotecan combination) with or without bevacizumab as second?line chemo?therapy for patients with mCRC. Patients with 20years of age or older, histologically conifrmed mCRC, Eastern Coop?erative Oncology Group performance status 0–2, adequate organ function, and disease progression or intolerance of the ifrst?line regimen will be eligible. Patients will be randomized (1:1) to receive standard FOLFIRI with or with?out bevacizumab (5mg/kg on day 1), repeated every 2weeks (FOLIRI arm) or XELIRI with or without bevacizumab (7.5mg/kg on day 1), repeated every 3weeks (XELIRI arm). A total of 464 events were estimated as necessary to show non?inferiority with a power of 80% at a one?sided α of 0.025, requiring a target sample size of 600 patients. The 95% conifdence interval (CI) upper limit of the hazard ratio was pre?speciifed as less than 1.3. Conclusion:The Asian XELIRI ProjecT is a multinational phase III trial being conducted to provide evidence for XELIRI with or without bevacizumab as a second?line treatment option of mCRC.

A 77-year-old man presented with fever and back pain. Computed tomography revealed a distal arch aneurysm. Bacteroides fragilis was found in a blood culture, and we diagnosed a thoracic infected aneurysm. Because of the rapid enlargement of the aneurysm and his frailty, a TEVAR procedure was urgently performed. He left the hospital after antibiotic treatment with meropenem. However, he was re-hospitalized due to recurrence of the infection. The infection was well-controlled by treatment with intravenous meropenem, and the subsequent oral administration of metronidazole (MNZ). He was re-hospitalized again 7 weeks after discharge due to unsteady gait and articulatory disorder. MNZ-induced encephalopathy (MIE) was diagnosed because FLAIR brain magnetic resonance imaging revealed an area of high signal intensity in the bilateral basal dentate nuclei. These symptoms improved after MNZ was changed to AMPC/CVA. Fifteen months later, the patient was doing well and had no recurrence of the infection. We performed TEVAR for a patient with a thoracic aneurysm infected by B. fragilis. The recurrence of the infection was controlled by adequate antibiotic therapy, which included the administration of MNZ. However, patients who are treated with MNZ should be carefully observed to detect the development of neurological signs, as MNZ may induce encephalopathy. The early detection and withdrawal of metronidazole is important for the improvement of MIE.

Objective: To report a case of anterior longitudinal ligament (ALL) injury that was not noticeable during lateral lumbar interbody fusion and was disclosed after posterior corrective fusion surgery.Case presentation: After performing lateral lumbar interbody fusion followed by posterior corrective fusion surgery, we observed an anterior longitudinal ligament rupture that required additional surgery. Postoperative pain in the left lower limb and muscle weakness due to nerve traction appeared, but this was improved by stabilization between the vertebral bodies.Conclusion: Unidentified anterior longitudinal ligament rupture can result in unexpected local lordosis during posterior surgery, possibly related to lower extremity palsy. Therefore, checking for possible rupture during and after anterior surgery is important. If the ALL damage is disclosed before posterior surgery, the proper surgical strategy for the posterior surgery must be considered.

Calcification of the ligamentum flavum (CLF), which is a rare disorder that can potentially cause myelopathy, occurs uncommonly in the thoracic spine. Here, we report a rare case of thoracic myelopathy caused by CLF in a 78-year-old man. Magnetic resonance imaging (MRI) showed posterior spinal cord compression by a hypo-signal intense mass, and computed tomography (CT) revealed CLF and vacuum disc phenomenon at T10/11. After undergoing posterior decompression and instrumented fusion (T9–T12), the patient’s gait difficulties improved. The pathogenesis of CLF is largely unknown; however, it involves accumulation of calcium pyrophosphate dehydrate crystals (CPPD), and CLF from CPPD deposition tends to occur within a thickened and hypertrophic ligament. CLF occurs predominantly in the cervical spine and less frequently in the lumbar spine, with few cases involving the thoraco-lumbar spine. The thoracic spine is characterized by hypomobility; however, the thoraco-lumbar spine has a mobile segment which may potentiate CLF formation. Decompression with fusion surgery can be useful for treating patients with thoraco-lumbar CLF.

The purpose of this study was to examine the impact of COVID-19 on home care at the end of life and the satisfaction of bereaved families. A questionnaire survey was conducted on 100 bereaved families of terminal cancer patients who were receiving home care. The effects of the COVID-19 on at-home medical treatment and the rate of satisfaction of bereaved families were examined. The response rate for this survey was 72.0%. Of the respondents, 52.8% of the bereaved families answered that the COVID-19 had an effect on their decision to choose home care. The rate of satisfaction of bereaved families was 98.6%. Even for terminal cancer patients who chose home care in the era of COVID-19 at our hospital, we were able to achieve high level of satisfaction for bereaved families.

Objective: To treat vertebral fractures with posterior wall injury in the elderly, vertebral bone grafting is generally performed through a posterior transpedicular approach, combined with pedicle screw fixation. An autologous bone is ideal to treat this disorder. However, harvesting autologous bones from the elderly with osteoporosis is limited by the amount and quality of available autologous bone. Thus, we developed a bone-grafting substitute. The newly developed unidirectional porous β-tricalcium phosphate, with a porosity of 57% (UDPTCP; Affinos®, Kuraray Co., Ltd., Tokyo, Japan), is used in the bone-grafting procedure. This is the first report of UDPTCP used as an artificial bone graft in patients with an acute vertebral burst fracture.Materials and Methods: UDPTCP (mean: 4.2 g) was implanted through the pedicle, and posterior instrumentation was achieved with pedicle screws in five elderly patients. Resorption of UDPTCP and substitution with the autologous bone were evaluated on computed tomography (CT) and plain X-ray performed immediately and at 3, 6, and 12 months after the operation.Results: In case 1, the pedicle screws did not loosen, and UDPTCP was completely resorbed and replaced with the autologous bone at 3 postoperative months. In the other four cases, although the pedicle screws or the caudal part loosened because of osteoporosis, resorption of UDPTCP was observed at 3 postoperative months. At 6 postoperative months, progressive substitution with the autologous bone was confirmed, and at 12 postoperative months, formation of the good autologous bone was confirmed.Conclusion: This preliminary case series demonstrated that the newly developed UDPTCP shows good clinical potential as a bone-graft substitute for acute vertebral burst fractures in the elderly, including patients with osteoporosis.
