Purpose:
Surgical resection of remnant gastric cancer (RGC) is technically challenging and difficult. Minimally invasive surgery (MIS) has been adopted for various procedures, but reports of MIS for RGC remain limited. Herein, we report the surgical techniques and short-term outcomes of MIS for RGC.
Methods:
We conducted a retrospective cohort study involving 61 consecutive RGC patients who underwent open or minimally invasive (laparoscopic or robotic) total gastrectomy for potentially curable RGC at our institution (January 1999–August 2025). A propensity scorematched cohort was used for an exploratory evaluation of the safety and efficacy of MIS for RGC, focusing on feasibility rather than superiority over open surgery.
Results:
Of these 61 patients, 53 underwent open surgery and eight underwent MIS gastrectomy for RGC. The median age was 70 years. The cohort comprised 53 men and eight women. The initial procedure was open surgery in 58 patients and MIS in three patients.Propensity score matching showed significantly reduced intraoperative blood loss in the MIS group compared with the open surgery group (39 mL vs. 576 mL, p < 0.05), and significantly longer operation time in the MIS group (352 minutes vs. 297 minutes, p < 0.05). Postoperative hospital stay was significantly shorter in the MIS group (12 days vs. 17 days, p < 0.05). The incidence of postoperative pancreatic fistula was lower in the MIS group, although not significantly different (0% vs. 16.7%).
Conclusion
MIS, including robotic gastrectomy, is feasible and safe for RGC, with potential perioperative benefits requiring multicenter validation.

Even within a hospital, the prognosis after a cardiac arrest is extremely poor if intervention starts only after the event; thus, early recognition and intervention is crucial to reduce inhospital cardiac arrests. This paper aims to assess the results of in-clinic surveys conducted for the implementation of the Rapid Response System (RRS) at our hospital and changes in awareness after awareness initiatives. Excluding the neonatal intensive care unit, all wards were targeted for implementation, with the creation of criteria for requesting the RRS and hospital-wide awareness initiatives. Four items were defined for the request criteria—namely, (1) respiration, (2) circulation, (3) state of consciousness, and (4) others (any concerns)—with a request being warranted if any one of these criteria was met. A pre-awareness survey revealed that respiratory rates were recorded only 6.9% of the time on average, indicating inadequate observation of respiratory rates across all wards. In response to this issue, we announced that respiratory status should be observed at least once a day, which resulted in the recording rate improving to 68.2% after 2 months. Survey results before and after the awareness initiatives among doctors and nurses showed a significant increase in RRS awareness. The percentage of nurses who answered “well aware” or “somewhat aware” increased from 34.8% to 77.6%, and from 63.4% to 88.0% among doctors. However, while the introduction of the RRS was relatively well-received by nurses struggling with on-site responses, some doctors questioned the necessity of the RRS. Upon implementation, it is important to make it known that it is a hospital-wide effort. Simplifying and thoroughly utilizing the request criteria can lead to early recognition of abnormalities. Since it is not easy to gain doctors’ understanding, it is necessary to listen to the needs and requests of each department and patiently continue awareness activities before implementation

COVID-19 spread from Wuhan City, People's Republic of China, in December 2019, followed by an explosion of infections worldwide. The number of infected people has also risen dramatically in Japan and has become a major social problem. Patients with severe disease require a long period to return to society due to significant physical weakness even after recovery. We report a patient in his 40s with a history of nephrectomy who was infected with COVID-19 and became critically ill.After being diagnosed with COVID-19 by PCR test, the patient was admitted to our hospital. His respiratory status rapidly worsened and he was temporarily managed by ECMO in the intensive care unit. At the time of his first contact with us (day 31 post-hospitalization), he was unable to hold himself in a standing position for a long time and required a walker. Initially, from the perspective of preventing the spread of infection, we instructed him in self-directed training rather than individual therapy. From day 49, he began to receive physical therapy. He was discharged on day 53 with independence in outdoor walking. He was instructed to consume protein after exercising and he was managed on an outpatient basis. He returned to work. His skeletal muscle mass increased by BIA and his respiratory and motor functions were restored.He received instructions on recovering from severe illness after COVID-19 infection, which focused on nutrition, voluntary training, and monitored individual therapy in accordance with rehabilitation therapy. He was able to return to society with no sequelae.

Background:
Massive rotator cuff tears (MRCTs) with subscapularis (SSC) tears cause severe shoulder dysfunction. In the present study, the influence of SSC tears on three-dimensional (3D) shoulder kinematics during scapular plane abduction in patients with MRCTs was examined.
Methods:
This study included 15 patients who were divided into two groups: supraspinatus (SSP) and infraspinatus (ISP) tears with SSC tear (torn SSC group: 10 shoulders) or without SSC tear (intact SSC group: 5 shoulders). Single-plane fluoroscopic images during scapular plane elevation and computed tomography (CT)-derived 3D bone models were matched to the fluoroscopic images using two-dimensional (2D)/3D registration techniques. Changes in 3D kinematic results were compared.
Results:
The humeral head center at the beginning of arm elevation was significantly higher in the torn SSC group than in the intact SSC group (1.8±3.4 mm vs. −1.1±1.6 mm, p<0.05). In the torn SSC group, the center of the humeral head migrated superiorly, then significantly downward at 60° arm elevation (p<0.05). In the intact SSC group, significant difference was not observed in the superior-inferior translation of the humeral head between the elevation angles.
Conclusions
In cases of MRCTs with a torn SSC, the center of the humeral head showed a superior translation at the initial phase of scapular plane abduction followed by inferior translation. These findings indicate the SSC muscle plays an important role in determining the dynamic stability of the glenohumeral joint in a superior-inferior direction in patients with MRCTs.

We report a case of transposition of the great arteries (TGA) with severe pulmonary hypertension from the right to left shunt in the right modified Blalock-Taussig shunt. The patient was diagnosed with TGA with a small ventricular septal defect, restrictive patent foramen ovale, and patent ductus arteriosus. Balloon atrial septostomy was performed, and an arterial switch operation (ASO) was planned. However, ASO was delayed during the neonatal period due to cerebral bleeding. Moreover, left outflow tract obstruction was noted ; hence, the surgical strategy was shifted to an atrial switch operation or Rastelli type operation. The patient was palliated at the age of 5 months with a right 4-mm Gore-Tex modified Blalock-Taussig shunt. After this procedure, he was followed up at the outpatient clinic with good saturation level. However, at 9 months, he revisited the hospital due to septic shock. His SpO2 was 60% in the upper right limbs and 40% in the upper left and lower limbs. Nitric oxide inhalation and 100% oxygen were administered to improve pulmonary hypertension and subsequent differential cyanosis. Pulmonary hypertension decreased from over-systemic to 70% of the systemic arterial pressure. The Senning procedure with a fenestration in an atrial baffle was successfully performed at the age of 1 year.

The patient was a 34-year-old woman who had been routinely monitored after receiving a childhood diagnosis of partial anomalous pulmonary venous connection, but unilaterally discontinued follow-up examinations after the age of 18. At 33 years of age, she was admitted to our hospital after a physical examination revealed an abnormal shadow on a chest X-ray. Transthoracic echocardiography detected an atrial septal defect (ASD), and contrast-enhanced computed tomography showed that the right lower pulmonary vein drained to the inferior vena cava. The patient was diagnosed with scimitar syndrome with ASD. Cardiac catheterization showed a pulmonary/systemic flow ratio (Qp/Qs) of 2.48 and a left-to-right shunt rate of 59.7%. Surgical treatment was deemed to be indicated. The right lower pulmonary vein was anastomosed to the anterolateral wall of the right atrium, and an intra-atrial baffle repair was performed from the orifice within the right atrium to the left atrium through the existing ASD using untreated fresh autologous pericardium. Two years after the operation, good blood flow was maintained within the baffle with no stenosis at the anastomotic site. This report describes a rare case of scimitar syndrome with ASD in an adult woman, and provides a review of the existing literature.

Idiopathic normal pressure hydrocephalus (iNPH) is a disorder observed in elderly patients causing gait disturbance, urinary incontinence and cognitive impairment. Due to the rapidly aging society, the number of patients with iNPH continues to increase yearly. However, iNPH is often overlooked because of its insidious and variable presentation. In the primary care setting, iNPH can be coincidentally discovered by neuroimaging findings, including disproportionately enlarged subarachnoid space hydrocephalus (DESH). We report two cases of iNPH in the elderly living alone that had different outcomes depending upon the availability of neurosurgery specialists. It is essential for primary care physicians to consult neurosurgeons without delay because prompt diagnosis and treatment can improve the patient's quality of life and prolong their duration of living at home.
