Usefulness of a novel, slim long syringe-like device for applying surgical mesh through a 5-mm trocar.

We developed a device for introducing surgical mesh through a 5-mm trocar during transabdominal preperitoneal hernia repair. This device is like a slim long syringe; it has a polypropylene outer sheath (outer diameter, 5.8 mm; inner diameter, 5.

[A Case of Resected Reactive Lymphoid Hyperplasia of Liver Suspected of Hepatocellular Carcinoma].

A 64-year-old woman who had chronic type C viral hepatitis was referred with a liver tumor detected by magnetic resonance imaging(MRI). She had a history of rheumatoid arthritis which was treated by methotrexate. Ethoxybenzyl-MRI(EOBMRI) showed a low signal in the T1-weighted imaging, a high signal in the T2-weighted imaging and a low signal in the hepatobiliary phase.

[Solitary Splenic Hilar Nodes Metastasis from Ovarian Cancer Managed by Splenectomy with Pancreas Tail].

Solitary splenic metastasis from cancer is known as a rare disorder in cancer patients. In the present study, we report our experience regarding pathophysiology and treatment tactics of the splenic metastasis caused by ovarian cancer after perioperative chemotherapy. A 50s female presented to our clinic complaining of growing solitary splenic hilar node in CT.

Impact of nutritional status on outcomes in laparoscopy-assisted gastrectomy.

Background: There is a high morbidity rate after digestive surgery in patients with nutritional disorders such as high body mass index and depletion of skeletal muscle.

Materials And Methods: The ratio of psoas muscle area to trunk area was defined as the Psoas and All trunk Ratio (PandA Ratio) and used as an index of the balance between muscle and adipose tissue. This ratio was determined in 77 patients undergoing laparoscopy-assisted gastrectomy (LAG) for gastric cancer.

[A Case of Trousseau's Syndrome Caused by CA19-9-Producing Gastric Cancer].

Trousseau's syndrome is a coagulation disorder occurring in cancer patients. In the present study, we report our experience regarding the pathophysiology and treatment strategies of this syndrome that is caused by CA19-9-producing gastric cancer during long term chemotherapy. A 60s male presented to our clinic; he was found to have a high level of CA19-9.

A novel procedure for introducing large sheet-type surgical material with a self-expanding origami structure using a slim trocar (chevron pleats procedure).

Background: Large sheet-type surgical materials (e.g., absorbable hemostat, adhesion barrier membranes, and flat surgical mesh) are difficult to introduce into a corporeal cavity using a 5-mm trocar; however, laparoscopic surgeries that use mainly 5-mm trocars are increasing.

Prognostic Impact of a Nutritional Index Including Muscle Volume in Stage 4 Colorectal Cancer.

Background: Nutritional status influences cancer prognosis. Measurement of the area of the psoas muscle on computed tomography is useful for evaluation of skeletal muscle mass and prediction of prognosis.

Patients And Methods: The psoas muscle index (PMI) was determined in 42 patients undergoing surgery for stage 4 colorectal cancer.

[Diagnostic problems in gastric cancer patients with sarcoidosis-case report and literature review].

Sarcoidosis is an idiopathic systemic disease with non-caseating granuloma that is reported to occur concomitantly with various malignant tumors. We report here a case of advanced gastric cancer with sarcoidosis, for which precise preoperative diagnosis was difficult. A 69-year-old woman was diagnosed with a far-advanced gastric cancer because multiple intra-abdominal and intra-thoracic lymph node swellings and a tumorous lesion in the spleen were detected by multidetector computed tomography and fluorodeoxyglucose positron emission tomography.
