A case report of gallbladder cancer and pancreas cystic neoplasm associated with pancreaticobiliary maljunction.

Introduction And Importance: Pancreaticobiliary maljunction (PBM) is a rare congenital anomaly that is frequently associated with carcinoma of the biliary tract. However, there is still no clear evidence that PBM is associated with pancreatic tumors. Here we describe a case of gallbladder cancer and intraductal papillary mucinous neoplasm (IPMN) that is associated with PBM.

Clinical characteristics of patients with pneumatosis intestinalis.

Background: Several theories explaining the development of pneumatosis intestinalis (PI) have been reported, but a substantial portion of cases have been idiopathic. Additionally, predictors of bowel ischaemia in PI have not been fully investigated, while PI with bowel ischaemia has deteriorated overall outcomes of PI.

Methods: Sixty-four patients diagnosed with PI (2009-2019) were allocated to two groups: with (group 1; n = 15 (23%)) and without (group 2; n = 49 (77%)) bowel ischaemia.

Clinical features of patients with hepatic portal venous gas.

Background: Hepatic portal venous gas (HPVG) is a rare clinical condition that is caused by a variety of underlying diseases. However, the factors that would permit accurate identification of bowel ischemia, requiring surgery, in patients with HPVG have not been fully investigated.

Methods: Thirty patients that had been diagnosed with HPVG using computed tomography between 2010 and 2019 were allocated to two groups on the basis of clinical and intraoperative findings: those with (Group 1; n = 12 [40%]) and without (Group 2; n = 18 [60%]) bowel ischemia.

Splenic artery aneurysm rupture during pregnancy: A case report of maternal and fetal survival.

Introduction: Pregnancy has been demonstrated as a significant risk factor of splenic artery aneurysm (SAA) formation and rupture. However, prompt diagnosis of SAA rupture in a pregnant patient showing acute abdomen has been practically challenging in light of its rarity and vague initial presentation.

Presentation Of Case: A 40-year-old woman (gravida 1, para 0) at 35 weeks' gestation presented to the emergency department with upper abdominal pain and nausea.

Surgical outcomes of hybrid hand-assisted laparoscopic pelvic exenteration for locally advanced rectal cancer: Initial experience.

Introduction: Hybrid hand-assisted laparoscopic surgery (HALS) combines better visualization of laparoscopic surgery with the advantages of open surgery. The aim of this study was to describe important technical considerations of HALS and to assess the feasibility of hybrid HALS pelvic exenteration (PE) for primary advanced rectal cancer.

Methods: From May 2012 to August 2018, we retrospectively analyzed 11 patients who underwent PE for primary advanced rectal cancer (< 10 cm from the anal verge).

A case of Lymphoepithelioma-like carcinoma (LELC) developed in the rectum.

Lymphoepithelioma-like carcinoma (LELC) is histologically similar in form to nasopharyngeal carcinoma (NPC) and is an epithelial tumor that is suggested to be involved in infection with Epstein-Barr virus (EBV), but it is rare to occur in the colon. A 35-year-old woman was found to have a rectal wall thickening by follow-up computed tomography (CT) image after sigmoidectomy and left salpingo-oophorectomy. Biopsy under colonoscopy revealed recurrence of ovarian cancer, and she underwent a low anterior resection.

Perioperative management of laparoscopic surgery in a patient with protein S deficiency complications: A case report.

Patients with protein S deficiency are prone to developing thrombosis. During laparoscopic surgery in patients with protein S deficiency, there is a risk of deep venous thromboembolism. In the present case, the patient was a 66-year-old man.

Characterization of SCC type IV methicillin-resistant clones increased in Japanese hospitals.

Recently, the prevalence of staphylococcal cassette chromosome (SCC) type IV isolates, which are the major community-acquired methicillin-resistant (MRSA), have increased in Japanese hospitals. The aim of this study was to elucidate the detailed molecular epidemiological features of the SCC type IV clones in Japanese hospitals. When 2589 MRSA isolated from four hospitals in Tokyo, Japan between 2010 and 2014 were analysed, the proportion of SCC type IV overtook that of type II, which was the major type of hospital-acquired MRSA in 2014.

Acute aortic occlusion in a patient with chronic paralysis due to spinal cord injury: a case report.

Patients with spinal cord injury experience changes in the cardiovascular system and a high morbidity associated with peripheral artery disease. We report a case of acute aortic occlusion in a patient with chronic paralysis due to spinal cord injury. A 65-year-old man with chronic paralysis due to spinal cord injury developed mottling of the right extremity.

Diffusion-weighted magnetic resonance imaging to differentiate malignant from benign gallbladder disorders.

Purpose: To retrospectively evaluate the utility of apparent diffusion coefficient (ADC) and lesion to spinal cord ratio (LSR) in diffusion-weighted magnetic resonance (MR) imaging (DWI) as compared with morphological assessment alone, for differentiating malignant from benign gallbladder disorders.

Methods: This study was approved by the ethics committee, and written informed consent was waived. Ninety-one patients (13 malignancy and 78 benignancy) were reviewed.

Gallbladder perforation associated with carcinoma of the duodenal papilla: a case report.

Background: Gallbladder perforation is a rare clinical condition, which mostly occurs following acute cholecystitis associated with cholelithiasis. A tumor of the ampulla of Vater causes gradually progressive symptoms, and is rarely associated with perforation of the gallbladder.

Case Presentation: A 56-year-old man with carcinoma of the ampulla of Vater presented with spontaneous gallbladder perforation and localized bile peritonitis.

Retroperitoneal mixed-type liposarcoma showing features of four different subtypes.

Mixed-type liposarcoma is a rare soft tissue tumor. This report describes a 50-year-old man with retroperitoneal mixed-type liposarcoma that consisted of four pathologically different components. Preoperative CT and MRI showed a giant retroperitoneal mass composed of several nodules with various attenuation and signal intensity.

Isolated periportal tuberculosis: characteristic findings of clinical imaging.

Isolated periportal tuberculous lymphadenopathy is a rare clinical entity. This report describes a 56-year-old woman with the disease, who showed characteristic findings on clinical imaging studies. Computed tomography showed a low-density mass with peripheral enhancement and calcification, adjacent to the pancreatic head and caudate lobe of the liver.

Pseudomyxoma peritonei presenting with femoral hernias and peritonitis.

Pseudomyxoma peritonei is a rare disease characterized by intraperitoneal accumulation of mucinous ascites produced by neoplastic cells, which mostly originate from an appendiceal adenoma. The clinical presentation of the disease varies, and preoperative diagnosis is often difficult. This report describes a 76-year-old female patient with pseudomyxoma peritonei who presented with lower abdominal pain and bilateral femoral masses.

[Anesthetic managements of the patients receiving catheterizable cecostomy].

To improve the quality of life of patients suffering from spinal cord injury, "Catheterizable cecostomy" operation have recently been carried out. In the procedure, cathetelizable stoma is opened and patients are able to control the excretion by injecting enema solution through the stoma. Although operations are usually performed under general anesthesia with tracheal intubation, special considerations sometimes need to be taken for airway management.

[A case of multiple hepatic and peritoneal metastases from colon cancer responding to oral UFT+leucovorin chemotherapy].

A 57-year-old woman underwent right hemicolectomy (D3) due to transverse colon cancer with multiple liver and peritoneal metastasis. Administration of oral UFT+Leucovorin was started postoperatively. After 6 months, the multiple liver metastases completely disappeared without any adverse reaction.
