Relationship Between the Relative Length of the Second Metatarsal and Occurrence of Metatarsalgia in Patients With Hallux Valgus.

Background: Patients with hallux valgus (HV) may develop metatarsalgia, which is partly attributed to second metatarsal relative length (RL2M). However, no study has analyzed RL2Ms measured by various methods as predictors for metatarsalgia in HV patients. This study aimed to investigate the predictors for metatarsalgia in HV patients and calculate the cutoff values for metatarsalgia in preoperative planning for lesser metatarsal shortening osteotomy.

Short-term Outcomes of Robot-assisted Colectomy Using the Overlap Method for Right-sided Colon Cancer.

Background/aim: The recent development of minimally invasive surgery has led to transition from laparoscopic right colectomy (LC) to robot-assisted right colectomy (RC) in Japan. However, it is unclear whether the introduction of RC in municipal hospitals could be as safe as that in high-volume centers in Japan. Therefore, this retrospective study aimed to compare the short-term operative outcomes of RC and LC for right colon cancer at a local municipal hospital in Japan.

Short-term Outcomes of Robotic Left Colectomy Reconstructed by Intracorporeal Overlap Anastomosis for Left-sided Colon Cancer: A Single-center Report from Japan.

Background/aim: Surgery for colon cancer requires covering a wide area and performing both tumor resection and precise lymph node dissection. Robotic left-sided colectomy (RLC) has not been thoroughly established due to the rarity of descending colon cancer. Therefore, we investigated 19 patients who underwent RLC for left-sided colon cancer.

Multiple calcifying fibrous tumors from gastric and retroperitoneal tissue: A case report.

Introduction And Importance: Calcifying fibrous tumor (CFT) is a rare benign mesenchymal lesion that has been occurred in the gastrointestinal tract, especially occurs most commonly in the stomach and the small and large intestines.

Case Presentation: 74-year-old woman was admitted to our hospital with complaints of epigastric discomfort. Whole-body computed tomography (CT) revealed a 2.

IRIS U kit usefulness in transanal total mesorectal excision for lower rectal cancer to avoid urethral injury.

Transanal total mesorectal excision (taTME) has improved the laparoscopic dissection for rectal cancer in the narrow pelvis. Although taTME has more clinical benefits than laparoscopic surgery, such as a better view of the distal rectum and direct determination of distal resection margin, an intraoperative urethral injury could occur in excision ta-TME. This study aimed to determine the feasibility and efficacy of the ta-TME with IRIS U kit surgery.

Laparoscopic splenectomy for sclerosing angiomatoid nodular transformation of the spleen: Report a case.

Introduction And Importance: Sclerosing angiomatoid nodular transformation (SANT) of the spleen is an extremely rare benign lesion.

Case Presentation: Here, we describe the case of a 52-year-woman who was diagnosed with sclerosing angiomatoid nodular transformation of the spleen. Abdominal contrast-enhanced CT revealed a solid lesion in the splenic hilum that was slowly enhanced between the portal venous and equilibrium phases incidentally.

Robotic transabdominal preperitoneal repair for recurrent inguinal hernia after Kugel hernioplasty: A case report.

Introduction And Importance: The laparoscopic posterior approach adapts the advantages of Kugel hernioplasty, making it possible to perform it at the new layer even if the inguinal hernia is recurrent following the anterior approach, producing a high level of completion. However, in laparoscopic surgery for recurrent inguinal hernia using posterior approaches, dissecting the extraperitoneal space is difficult. Robotic surgery may enable precise dissection, even if the space is severely adhered.

Langerhans Cell Histiocytosis With Unusual Hexagonal Crystals in Addition to Usual Charcot-Leyden Crystals. Report of a Patient With Possible Process of Crystal Formation and Clinical Significance of a "Necrotic" Change.

Langerhans cell histiocytosis is a rare neoplastic disorder characterized by the proliferation of Langerhans cells and often accompanied by eosinophil infiltration. Charcot-Leyden crystals, composed of galectin 10, are occasionally observed in Langerhans cell histiocytosis; however, histological images are rarely reported. We herein present a patient with Langerhans cell histiocytosis with Charcot-Leyden crystals and hexagonal crystals by describing the histologic and immunohistochemical features of a lymph node.

Successful treatment of atypical femoral fracture with autogenous bone grafting in a patient on denosumab for bone metastasis from breast cancer: A case report.

Atypical femoral fractures (AFFs) occur with minor trauma and are believed to be a potential complication of the prolonged use of antiresorptive agents, such as bisphosphonate and denosumab, for the treatment of bone metastasis. In comparison with typical femoral fractures, AFFs have a higher incidence of complications, including implant failure and delayed union or nonunion. This report describes the case of a 42-year-old woman who developed denosumab-associated AFF after denosumab therapy for bone metastasis from breast cancer.

[Microvascular Decompression for Trigeminal Neuralgia Caused by Trigeminocerebellar Artery].

The trigeminocerebellar artery(TCA)is a unique branch of the basilar artery. The TCA was first described in detail by Markovic et al. in 1996.

[Developmental History of Microvascular Decompression Surgery for Cranial Nerve Dysfunction].

Trigeminal neuralgia is characterized by severe lancinating pain in the face and hemifacial spasms displayed by continuous facial muscle twitching, which may impair a patient's quality of life. Before 1960, in the United States of America, the treatment of such symptoms was only partial rhizotomy of the cranial nerves, which resulted in postoperative complications. Afterwards, in the late 1960s, it became evident that the etiology of symptoms was an elicited arterial compression of the cranial nerves at the "Root Entry/Exit zone.

Radiofrequency Catheter Ablation for Atrial Fibrillation Patients on Hemodialysis (From the Kansai Plus Atrial Fibrillation Registry) - Clinical Impact of Early Recurrence.

Background: Catheter ablation (CA) for atrial fibrillation (AF) in patients on hemodialysis (HD) is reported to have a high risk of late recurrence (LR). However, the relationship between early recurrence (ER) within a 90-day blanking period after CA in AF patients and LR in HD patients remains unclear.

Methods and results: Of the 5,010 patients in the Kansai Plus Atrial Fibrillation Registry, 5,009 were included in the present study.

Bilateral laparosocopic lateral lymph node dissection by the totally extraperitoneal approach after intersphincteric resection of the lower rectum: report of a case.

Introduction And Importance: Lateral lymph node dissection (LLND) for recurrent lateral pelvic lymph node metastasis could be the only surgical treatment to improve its prognosis, but is difficult and challenging technically.

Case Presentation: A 75-year-old Japanese man who underwent a radical laparoscopic intersphincteric resection to treat double lower rectal cancer. Computed tomography and MRI showed lower rectal wall thickening and bilateral lateral lymph node swelling.

Intraplaque wiring enables drug-coated balloons to be utilized for percutaneous recanalization of chronically occluded coronary arteries.

Objectives: This study aimed to determine whether drug-coated balloon (DCB) angioplasty following intraplaque wiring and the use of modified balloons is safe and effective in the percutaneous treatment of coronary chronic total occlusions (CTOs).

Background: DCB is an alternative therapeutic option without the limitations of permanent vascular implants. However, its efficacy in CTOs has yet to be confirmed.

Examination on Factors Affecting Symptom Change after Drug Withdrawal in Patients with Mild Erosive Gastroesophageal Reflux Disease Undergoing Symptom-Controlled Maintenance Therapy with Acid-Secretion Inhibition Drugs.

Introduction: In patients with gastroesophageal reflux disease (GERD) on maintenance therapy with acid-suppressive drugs, it is not clear what background factors allow patients to discontinue the drugs. The aims of this study were to examine the relationship of the changes in the frequency and severity of gastrointestinal symptoms after discontinuation of acid-secretion inhibitors for erosive GERD (eGERD) with possible patient background factors and to identify factors that influence these changes.

Methods: This is a multicenter, open-label, interventional, exploratory study.

Successful treatment for sports hernia by total extraperitoneal repair with intraperitoneal examination: Report a case.

Introduction: and importance: TEP might be one of options for treating such a sports hernia.

Case Presentation: An 18-year-old Japanese male presented with right groin pain for approximately two years. The pain was initially felt on the right side only, especially on kicking.

Global Impact of the COVID-19 Pandemic on Stroke Volumes and Cerebrovascular Events: A 1-Year Follow-up.

Background And Objectives: Declines in stroke admission, IV thrombolysis (IVT), and mechanical thrombectomy volumes were reported during the first wave of the COVID-19 pandemic. There is a paucity of data on the longer-term effect of the pandemic on stroke volumes over the course of a year and through the second wave of the pandemic. We sought to measure the effect of the COVID-19 pandemic on the volumes of stroke admissions, intracranial hemorrhage (ICH), IVT, and mechanical thrombectomy over a 1-year period at the onset of the pandemic (March 1, 2020, to February 28, 2021) compared with the immediately preceding year (March 1, 2019, to February 29, 2020).

Postoperative results of the in situ fenestrated open stent technique for acute aortic dissection type A.

Objective: Total arch replacement is commonly used for acute aortic dissection type A at some facilities, especially since open stent grafting became commercially available in Japan. Left subclavian artery (LSCA) reconstruction involves deep view manipulation, is difficult to expose and anastomose, and involves the risk of complications and surrounding vascular injury.

Methods: We evaluated 137 patients (mean age 73.

Thyroid-Stimulating Hormone, Age, and Tumor Size are Risk Factors for Progression During Active Surveillance of Low-Risk Papillary Thyroid Microcarcinoma in Adults.

Background: Active surveillance (AS) of low-risk papillary thyroid microcarcinoma (PTMC) was initiated at Kuma Hospital in 1993 and is gradually spreading worldwide. We assessed the effect of thyroid-stimulating hormone (TSH) levels on PTMC enlargement in patients on AS.

Methods: We enrolled 2705 patients with cytologically diagnosed PTMC who had undergone AS between January 2005 and July 2019.
