[A case of giardiasis diagnosed from a high output stoma after surgery for obstructive colorectal cancer].

This report describes a case of giardiasis detected through stool smear analysis of postoperative stool fluid collected from a high output stoma for obstructive colorectal cancer. The patient, a 67-year-old male, underwent right hemicolectomy with ileostomy for obstructive colorectal cancer. The persistent excessive excretion of postoperative stool fluid from the stoma prompted a stool smear test.

Large uterine arteriovenous malformation successfully treated with combined endovascular treatment and supracervical hysterectomy: A case report.

Uterine arteriovenous malformations (AVMs) are rare conditions that cause life-threatening bleeding. Endovascular treatment or total hysterectomy is performed to safely treat most AVMs. This case report describes a 54-year-old female patient with a large uterine AVM, uterine bleeding, and cardiac overload that was difficult to manage but successfully treated.

[F]FB(ePEG12)12-exendin-4 noninvasive imaging of insulinoma negative for insulin immunostaining on specimen from endoscopic ultrasonography-guided fine needle aspiration: a case report with review of literature.

Insulinomas are the most common functional pancreatic neuroendocrine neoplasm; when treatment is delayed, they induce hyperinsulinemic hypoglycemia, which is life-threatening. As surgical resection is the only curative treatment for insulinoma, preoperative localization is crucial; however, localization based on conventional imaging modalities such as computed tomography (CT) and magnetic resonance imaging is often inconclusive. Somatostatin receptor-targeted imaging is another option for detecting pancreatic neuroendocrine neoplasms but has low sensitivity and is not specific for insulinoma.

Association Between Pancreatic Cysts and Diabetes Mellitus in Von Hippel-Lindau Disease.

Introduction: Pancreatic cysts are frequently observed in patients with von Hippel-Lindau disease (VHL), and they are considered clinically not important. This study aimed to evaluate the association between pancreatic cysts and diabetes mellitus (DM) in patients with VHL.

Methods: Among patients who were on a patient list at the VHL Center at Kyoto University Hospital as of December 2022, those who had undergone an upper abdominal magnetic resonance imaging study after 2010 were retrospectively evaluated.

We present the case of a 44-year-old woman who developed bile leakage after a living-donor liver transplantation for locally advanced cholangiocarcinoma. A percutaneous drainage tube was placed in the segment 8 bile duct via the blind end of the jejunum.

Recurrence of unilateral angioedema of the tongue: A case report.

Background: Angioedema is a disorder characterized by edema of the face, lips, tongue, and extremities due to increased vascular permeability. Angioedema of the tongue usually occurs bilaterally, and the incidence of unilateral angioedema of the tongue is rare. This study reports a rare case of unilateral angioedema of the tongue with no identifiable cause and repeated recurrence even after discontinuation of an angiotensin-converting enzyme inhibitor.

F-labeled PEGylated exendin-4 imaging noninvasively differentiates insulinoma from an accessory spleen: the first case report of [18F]FB(ePEG12)12-exendin-4 positron emission tomography/computed tomography for insulinoma.

Background: Insulinomas are the most common functioning pancreatic neuroendocrine neoplasms, and these tumors induce hypoglycemia due to hyperinsulinemia. Hypoglycemia caused by insulinomas can cause seizures, coma or death due to the delayed diagnosis. The only curative treatment is surgical resection.

Percutaneous Transhepatic Biliary Intervention in Adult Biliary Atresia Patients After Kasai Portoenterostomy.

Kasai portoenterostomy (KP) is a standard treatment for patients with biliary atresia (BA). After KP, patients with BA occasionally develop biliary complications, such as recurrent cholangitis, biliary stricture, and cystic dilatation of the intrahepatic bile duct. Percutaneous transhepatic biliary drainage is one of the treatment options for these biliary complications.

Primary hepatic extranodal marginal zone B-cell mucosa-associated lymphoid tissue lymphoma treated by laparoscopic partial hepatectomy: a case report.

Background: Primary hepatic extranodal marginal zone B-cell mucosa-associated lymphoid tissue (MALT) lymphoma is very rare, so it is difficult to diagnose preoperatively. And there is no established treatment for hepatic MALT lymphoma. We report herein a case of primary hepatic MALT lymphoma treated by laparoscopic partial hepatectomy, and discuss the usefulness of laparoscopic hepatectomy for a rare liver tumor.

Transcatheter arterial embolization of the subclavian and axillary artery branches for hemorrhage control.

Objective: To evaluate the effectiveness and safety of transcatheter arterial embolization (TAE) of the branches of the subclavian and axillary arteries for hemorrhage control.
