An adult right inguinal hernia and cryptorchidism treated simultaneously with laparoscopic transabdominal preperitoneal repair and laparoscopic orchiectomy: a case report.

Pediatric health checkups have been mandatory for all citizens since 1966 based on the Maternal and Child Health Law in Japan, and cryptorchidism or undescended testis in adult males are rare. We report a case of an adult right inguinal hernia and cryptorchidism treated simultaneously with laparoscopic transabdominal preperitoneal repair and laparoscopic orchiectomy. A 35-year-old man came to our department with a chief complaint of bulging in the right inguinal region for several months.

Perforated Duodenal Diverticulum With Postoperative Diverticulum Bleeding Successfully Treated Using Transcatheter Arterial Embolization.

A diverticulum is a relatively common finding that is generally discovered incidentally; it is most commonly observed in the colon, followed by the duodenum. However, duodenal diverticulum perforation (DDP) is a rare complication. Due to its rarity, its diagnosis is often challenging and the appropriate treatment remains unclear, possibly contributing to its high mortality rate.

The EPOS-CC Score: An Integration of Independent, Tumor- and Patient-Associated Risk Factors to Predict 5-years Overall Survival Following Colorectal Cancer Surgery.

Background: Surgical audit is an essential task for the estimation of postoperative outcome and comparison of quality of care. Previous studies on surgical audits focused on short-term outcomes, such as postoperative mortality. We propose a surgical audit evaluating long-term outcome following colorectal cancer surgery.

Tracheo-Bronchial Obstruction and Esophageal Perforation after TEVAR for Thoracic Aortic Rupture.

A 67-year-old man was referred to our hospital for an ascending aortic aneurysm, thoracoabdominal aortic aneurysm and aortic regurgitation. Graft repair of the thoracic aortic arch and aortic valve replacement was given priority and completed, however he developed descending aortic rupture before the second scheduled surgery, and endovascular stent grafting was performed. He subsequently developed tracheobronchial obstruction and esophageal perforation.

Delayed esophageal perforation secondary to thoracic aortic aneurysm rupture in a patient with human immunodeficiency virus infection.

A 65-year-old man infected with human immunodeficiency virus underwent emergency surgery for rupture of a mycotic descending thoracic aneurysm. The aneurysm was replaced with a prosthetic graft wrapped with omentum. Esophageal perforation occurred 3 weeks after surgery.

Risk factors for catheter-related bloodstream infections in adult hospitalized patients - multicenter cohort study.

Background: Risk factors for catheter-related bloodstream infections (CRBSIs) may change over time with progress in infection control. This study was undertaken to explore the current risk factors for CRBSIs in hospitalized patients.

Methods: Adult patients with non-tunneled central venous catheters (CVCs) in 12 Japanese referral hospitals were prospectively enrolled between December 2009 and January 2012.

A reversal in the vascularity of metastatic liver tumors from colorectal cancer after the cessation of chemotherapy plus bevacizumab: contrast-enhanced ultrasonography and histological examination.

Objective: To assess the effect of chemotherapy plus bevacizumab on tumor vessels, as well as the reversibility of this effect, using contrast-enhanced ultrasonography (CEUS) and histology in patients with metastatic liver tumors derived from colorectal cancer.

Methods: The study included 12 patients who received chemotherapy plus bevacizumab, experienced a reduction in tumor vascularity as demonstrated by CEUS and consequently underwent liver resection. CEUS was performed before and after four courses of chemotherapy and before surgery.

[alpha-fetoprotein producing rectal cancer].

A 73-year-old man with a diagnosis of rectal cancer concomitant with multiple liver metastases underwent resection of the primary lesion. The postoperative immunohistochemical study revealed AFP production in the cancer tissue. The initial serum level of AFP after operation was 721 ng/mL.

A case of primary biliary cirrhosis that complicated with combined hepatocellular and cholangiocellular carcinoma.

Primary biliary cirrhosis (PBC) is frequently complicated with hepatocellular carcinoma (HCC), but complication with combined hepatocellular and cholangiocellular carcinoma (cHCC-CC) or cholangiocellular carcinoma (CCC) has not been reported. Here, we describe a case of PBC in which cHCC-CC occurred. The patient was a 70-year-old man who had developed jaundice at 62 years old.

A multicenter prospective study of surgical audit systems.

Objective: This study was undertaken to evaluate a modified form of Estimation of Physiologic Ability and Surgical Stress (E-PASS) for surgical audit comparing with other existing models.

Background: Although several scoring systems have been devised for surgical audit, no nation-wide survey has been performed yet.

Methods: We modified our previous E-PASS surgical audit system by computing the weights of 41 procedures, using data from 4925 patients who underwent elective digestive surgery, designated it as mE-PASS.

A case of granulocyte-colony stimulating factor-producing hepatocellular carcinoma confirmed by immunohistochemistry.

Granulocyte-colony stimulating factor (G-CSF) is a naturally occurring glycoprotein that stimulates the proliferation and maturation of precursor cells in the bone marrow into fully differentiated neutrophils. Several reports of G-CSF-producing malignant tumors have been published, but scarcely any in the hepatobiliary system, such as in hepatocellular carcinoma (HCC). Here, we encountered a 69-yr-old man with a hepatic tumor who had received right hepatic resection.

Impairment of changes in the diameter of the pancreatic portion of the superior mesenteric vein: an ultrasonographic sign of chronic pancreatitis or fibrosis.

Objective: A new ultrasonographic technique for detecting parenchymal stiffness of the pancreas is proposed. This technique measures changes in the diameter of the origin of the superior mesenteric vein (SMV) induced by deep inspiration. The origin of the SMV has extensive attachments to the pancreatic parenchyma; therefore, both physiologic enlargement and shrinkage of the venous lumen cannot occur without changes in the shape of the surrounding parenchyma.

New prediction rule for mortality in acute mesenteric ischemia.

Objective: Acute mesenteric ischemia is potentially fatal, but prognostic factors have not yet been established. This study was undertaken to elucidate them.

Methods: This is a retrospective cohort study, consisting of 110 patients who had been treated in the past 5 years, from 26 national hospitals in Japan.

[A case of nonocclusive mesenteric ischemia (NOMI) which occurred in a patient with torsion of gallbladder].

We report a case of nonocclusive mesenteric ischemia (NOMI) which occurred in a patient with torsion of gallbladder. A 91-year-old woman was admitted to the hospital and was diagnosed of acute cholecystitis. The next day, she went into shock.
