Improved Preservation of Rat Small Intestine Transplantation Graft by Introduction of Mesenchymal Stem Cell-Secreted Fractions.

Segmental grafts from living donors have advantages over grafts from deceased donors when used for small intestine transplantation. However, storage time for small intestine grafts can be extremely short and optimal graft preservation conditions for short-term storage remain undetermined. Secreted factors from mesenchymal stem cells (MSCs) that allow direct activation of preserved small intestine grafts.

Changes in thoracic radio density after living donor liver transplantation.

Background: The outcomes after liver transplantation have greatly improved, which has resulted in greater focus on improving non-hepatic outcomes of liver transplantation. The present study aimed to evaluate thoracic spine radio density in children and adolescents after liver transplantation.

Methods: A total of 116 patients who underwent living donor liver transplantation were retrospectively analyzed.

Wearing masks is easy but taking them off is difficult - A situation in Japan during COVID-19 pandemic and after.

Background: Masks are well accepted in Japan, where they were already part of daily life even before the COVID-19 pandemic. Unlike many other countries where mask mandates were lifted as soon as the pandemic was under control, Japan was one of the last countries to ease mask-wearing guidelines. Even after the formal announcement to allow masks-off in mid-March 2023, many Japanese still voluntarily wear masks.

Naldemedine is associated with earlier defecation in critically ill patients with opioid-induced constipation: A retrospective, single-center cohort study.

Introduction: There are few reports describing the association of naldemedine with defecation in critically ill patients with opioid-induced constipation. The purpose of this study was to determine whether naldemedine is associated with earlier defecation in critically ill patients with opioid-induced constipation.

Methods: In this retrospective cohort study, patients admitted to the Intensive Care Unit (ICU) without defecation for 48 hours while receiving opioids were eligible for enrollment.

Repeat bidirectional double-balloon enteroscopy 1 year later may be proper in Peutz-Jeghers patients with difficult-to-reach polyps.

Small-bowel polyps in patients with Peutz-Jeghers syndrome (PJS) are sometimes difficult to reach using double-balloon enteroscopy (DBE). However, they can induce intussusception, especially when ≧15 mm. This study aimed to review the outcomes of patients with such polyps.

Combined Intraperitoneal Paclitaxel and Systemic Chemotherapy for Patients with Massive Malignant Ascites Secondary to Pancreatic Cancer: A Report of Two Patients.

The prognosis of patients with peritoneal metastases from pancreatic cancer is poor, largely due to massive ascites, which precludes systemic treatment. Two patients with a poor performance status and malignant ascites were treated with cell-free and concentrated ascites reinfusion therapy followed by combined chemotherapy with intraperitoneal paclitaxel, intravenous gemcitabine, and nab-paclitaxel. These patients achieved a survival of 19 and 36 weeks with a relatively good quality of life.

Remnant liver function is associated with long-term survival in patients with hepatocellular carcinoma undergoing hepatectomy.

It is important to assess the prognosis and intervene before and after surgery in patients with hepatocellular carcinoma. This study aims to elucidate the association of outcomes and residual liver function after hepatectomy. A total of 176 patients who underwent the initial resection for hepatocellular carcinoma between January 2011 and March 2021 at Jichi Medical University were included.

Pancreatitis and cholangitis caused by metallic wire in the duodenal submucosa and muscularis near the papilla: removal by endoscopic submucosal dissection using the pocket-creation method.

Video 1A metalic wire removed by endoscopic submucosal dissection using the pocket-creation method.

Laparoscopic sleeve gastrectomy followed by laparoscopic adrenalectomy for patients with obesity and primary aldosteronism: Report of two patients.

Introduction And Importance: Primary aldosteronism (PA) is the most frequent cause of secondary hypertension. Surgical treatment of unilateral PA usually resolves excessive aldosterone secretion. Obesity is an independent factor for postoperative persistent hypertension for patients with unilateral PA.

Measuring and maintaining organ perfusion in a patient with Takayasu's arteritis undergoing cardiac surgery.

Takayasu's arteritis is a rare vasculitis affecting the aorta and its branches. Disease progression can result in arterial stenosis and subsequent organ dysfunction. Estimating organ perfusion by measuring the peripheral blood pressure can be challenging because it may be altered by arterial stenosis.

Type B2 vessels and infiltrative growth patterns b and c are associated with lymphatic invasion in pT1a-lamina propria mucosa esophageal squamous cell carcinoma.

Background: Tumor growth pattern correlates with outcomes in patients with esophageal squamous cell carcinoma (ESCC), however, the clinical significance of the tumor growth pattern in pT1a-lamina propria mucosa (LPM) type of ESCC was unclear. This study was conducted to clarify clinicopathological features of tumor growth patterns in pT1a-LPM type ESCC and the relationship between tumor growth patterns and magnifying endoscopic findings.

Methods: Eighty-seven lesions diagnosed as pT1a-LPM ESCC were included.

Factors associated with the need for long-term total parenteral nutrition in survivors of acute superior mesenteric artery occlusion.

Background: Acute superior mesenteric artery (SMA) occlusion is an uncommon condition associated with high mortality. If extensive bowel resection is performed for patients with acute SMA occlusion and the patient survives, long-term total parenteral nutrition (TPN) may be needed due to short bowel syndrome. This study examined factors associated with the need for long-term TPN after the treatment of acute SMA occlusion.
