Background/Aims: Endoscopic submucosal dissection (ESD) for superficial non-ampullary duodenal epithelial tumors (SNADETs) is technically challenging and is associated with a risk of adverse events, particularly when lesions are located near the major papilla. Pancreatic duct (PD) stent may reduce the risk of post-ESD pancreatitis; however, no standard strategy has been established. This study aimed to evaluate the effectiveness and safety of PD stent placement combined with ESD for SNADETs near the major papilla. Methods: This was a retrospective study of duodenal ESD after prophylactic PD stent placement in patients with SNADET near the major papilla at a university hospital between March 2014 and September 2023. Results: Four lesions were located within 5 mm of the major papilla, and seven within 5 to 10 mm. The median interval between stent placement and ESD was 2 days. The en bloc and R0 resection rates were 100% and 90.9%, respectively. No stent migration occurred during ESD, and all mucosal defects were completely closed using endoscopic clips. Delayed bleeding and post-ESD pancreatitis were observed in one and two cases, respectively. Conclusions PD stent placement combined with ESD is an effective treatment strategy for SNADETs near the major papilla. However, the risk of post-ESD pancreatitis remains, indicating the need for further preventive strategies.

We herein report a case of a 19-year-old male patient who presented with traumatic alopecia and was successfully treated with Kampo formulation saikoseikanto (Ikkando). This patient was referred to the Kampo outpatient department of Hoshi General Hospital from a neurosurgery hospital located near his workplace. The reason for the consultation was alopecia with subcutaneous hemorrhage that appeared several days after a blow to his parietal region. The patient presented with kyokyokuman on the right side along with chronic pharyngitis. We suspected that the alopecia was caused by folliculitis, so we prescribed saikoseikanto. The results of this medication were dramatic ; his alopecia and pharyngeal inflammation resolved within three months. His depressive mental state and his irritability improved significantly. We recognized that this Kampo formulation controlled both physical and mental disorders.

We herein report a case of a 72-year-old man who complained of recurrent hyperalgesia in the right big toe, which was successfully treated with the Kampo formulation ninjin’yoeito. The unusual pain felt like being cut with a utility knife whenever his skin was lightly scraped with a toothpick. There was mild tactile loss at this area, however, there were no other sensory disturbances in the sense of pain, cold, or vibration. This patient’s hobby was Iaido, a type of Kendo, which places stress on the soles of the feet. Therefore, we speculated that the clinical disorder in this case was related to his exercise. This patient exhibited a pattern of qi and blood deficiency with qi uprising, which suggested the use of ninjin’yoeito. After taking this Kampo formulation, his abnormal hyperalgesia with coldness in the big toe resolved. There have been no prior reports of ninjin’yoeito effectively treating unusual hyperalgesia.

We herein report the case of a 68-year-old female patient whose branch-type intraductal papillary mucinous neoplasm (IPMN) regressed during thirteen years of Kampo treatment. The Kampo treatment was not aimed at treating IPMN but rather at addressing her complex complaints, such as menopausal disorders, chronic headaches and abdominal pain. During this period, her IPMN was monitored by MRCP every year without any medication or surgical intervention. The regression of IPMN is extremely rare. Therefore, we report this case by presenting the course of MRCP images along with an overview of Kampo treatment over these thirteen years.

A 55-year-old woman with fever and consciousness disorder diagnosed as infective endocarditis was transported to our hospital. She had atopic dermatitis. A mobile vegetation at the mitral valve was revealed by the transesophageal echocardiography, and a computed tomography (CT) scan showed cerebral infarction, left renal infarction and suspected embolization of the vegetation. Streptococcus aureus was detected in the blood culture test. We conducted emergent surgery, mitral valve plasty was performed. On the second day after the operation, the hemoglobin began to decrease, and the hemodynamics became unstable. The contrast CT examination revealed arterial bleeding from the left kidney, which had an infarction before the operation. We performed emergent catheter liquid embolization for the superior polar branch of the left renal artery, and the hemodynamics improved thereafter. There has been no report of renal hemorrhage after cardiac surgery for infective endocarditis. This case reminded us that cardiac surgery for infective endocarditis may cause various complications of organs.

We report a case of a 72-year-old woman with a tumor arising from a colostomy site that had been created 25 years earlier when rectal amputation was performed for perforated sigmoid cancer. She was referred to our hospital due to complaints of pain from the colostomy. The diagnosis was carcinoma arising at the colostomy site with lymph node metastasis. Laparoscopic surgery was performed by attaching an Applied Alexis® wound retractor to the incision site of the colostomy. Lymph node dissection was performed and the left hemicolon was resected. Carcinoma arising from a colostomy site is rare. Laparoscopic surgery was considered to be a useful procedure because it allows for lymph node dissection and intestinal mobilization with minimal invasiveness.

Non-alcoholic fatty liver disease is currently the most common chronic liver disease, affecting up to 25% of the global population. Simple fatty liver, in which fat is deposited in the liver without fibrosis, has been regarded as a benign disease in the past, but it is now known to be prognostic. In the future, more emphasis should be placed on the quantification of liver fat. Traditionally, fatty liver has been assessed by histological evaluation, which requires an invasive examination; however, technological innovations have made it possible to evaluate fatty liver by non-invasive imaging methods, such as ultrasonography, computed tomography, and magnetic resonance imaging. In addition, quantitative as well as qualitative measurements for the detection of fatty liver have become available. In this review, we summarize the currently used qualitative evaluations of fatty liver and discuss quantitative evaluations that are expected to further develop in the future.

We herein report three patients who complained atypical febrile diseases associated with painful whole body (Case 1), general fatigue (Case 2), and a sense of general discomfort (Case 3). All cases were not accompanied by dizziness and a shaky feeling which are commonly associated in shimbuto-sho i.e. indication of shimbuto, but presented severe tenderness at the left paraumbilical region which was suggested as indicative point of shimbuto by Yoshiko Takagi. We made a diagnosis in these three cases as shimbuto-sho based on the Takagi's tender point. Through these clinical experiences we propose that a new type of shimbuto-sho, which are completely different from the fixed idea of inherited knowledge. This new type of shimbuto-sho consists of following signs ; fever with chill, floating and feeble pulse, no sweating, general fatigue or body pain, and severe pain at Takagi's tender point.

We herein report a 36-year-old male patient, who complained of persistent and recurrent nausea with vomiting for 16 years in spite of various standard treatments, was successfully treated with Kampo formulation Shimbuto, which selected based on the left para-navel tender point. We speculated that the clinical disorder in this case was related to suitai i.e. water imbalance syndrome in Kampo medicine. However, there has never been such a case report in the field of Kampo, and no related papers have been found in the standard database Medline. We believe this report is valuable from the viewpoint of therapeutics in both Western and Kampo medicine.
