Association between the paracaval branches of the caudate lobe and the three major hepatic veins in liver casts: Locating the cranial boundary of the caudate lobe.

According to Couinaud's definition, the cranial boundary of the caudate lobe is delineated by the three major hepatic veins. However, many branches of the caudate lobe go through the ceiling that is composed of these hepatic veins. The cranial boundary of the caudate lobe should be determined by employing the portal segmentation.

Right hemihepatectomy preserving the fluorescently visible paracaval portion of the caudate lobe.

The paracaval portion (PC) of the caudate lobe is a small area of the liver located in front of the inferior vena cava. Conventional right hemihepatectomy (RH) along the Rex-Cantlie line involves resection of not only the anterior and posterior sections but also the PC behind the middle hepatic vein (MHV). However, to preserve the future liver remnant volume as much as possible, PC-preserving RH may be beneficial in selected patients.

Demonstration of the right-side boundary of the caudate lobe in a liver cast.

There have been historical arguments about the boundary of the caudate lobe of the liver. Kumon M first advocated the definition of the caudate lobe based on the portal segmentation of the liver in 1985, and classified it into three parts, Spiegel lobe, paracaval portion and caudate process. Prof.

[Curative Resection for Advanced Gastric Cancer with Lymph Node Metastasis along the Middle Colic Artery].

Mesenteric lymph node metastasis of gastric cancer is extremely rare. We report the case of a patient with advanced gastric cancer having lymph node metastasis in the transverse mesocolon who underwent gastrectomy with lymph node dissection followed by chemotherapy. A 74-year-old male complaining of tarry stool was referred to our hospital for further examination following a diagnosis of gastric cancer by a local medical doctor.

Definition of the caudate lobe of the liver based on portal segmentation.

Models of liver corrosion were developed by injecting colored Mercox, epoxy resin, silicon rubber and other materials into the portal vein, hepatic artery, bile duct and hepatic vein of autopsied livers. The glissonean or venous branches that obstructed the view of the caudate lobe of the liver were subsequently removed. The detailed anatomy of the caudate vessels was studied and the three parts of the caudate lobe (Spiegel lobe, paracaval portion and caudate process) were defined based on portal segmentation.

Incidence and risk factors of osteoporotic status in outpatients who underwent gastrectomy for gastric cancer.

Background And Aim: Disorders in bone metabolism have long been recognized as typical sequelae of gastrectomy; however, the pathogenesis has not been fully elucidated, resulting in a variation of reported incidence. This study aimed to evaluate current bone health by measuring bone mineral density (BMD) in patients treated by gastrectomy for gastric cancer, with a focus on incidence and risk factors of osteoporosis.

Methods: The study enrolled 81 patients who underwent gastrectomy for gastric cancer at Kochi Medical School.

[Multidisciplinary Treatment for a Patient with Recurrent Gastric Cancer, Presenting 13 Years after the Radical Gastrectomy].

A 72-year-old woman was referred to our hospital for further examination of para-aortic lymph node swelling and elevated carbohydrate antigen 19-9 levels. Thirteen years ago, she had undergone distal gastrectomy for gastric cancer, and the final diagnosis was T4N1M0, Stage ⅢA. Abdominal contrast-enhanced computed tomography(CT)showed an enlarged para-aortic lymph node measuring 25 mm.

Anatomical Study of the Caudate Lobe with Special Reference to Portal Venous and Biliary Branches Using Corrosion Liver Casts and Clinical Application.

The definition and extent of the human caudate lobe in the liver is unclear, and thus, the anatomy of the caudate lobe was studied using 23 corrosion liver casts, with special reference to the portal venous and biliary branches. These branches and their ramification type in the caudate lobe showed that this lobe includes: (1) the Spiegel lobe; (2) the paracaval portion; and (3) the caudate process portion. The three portions often have their own independent branches; for example, the portal venous and biliary branches of the Spiegel lobe were ramified mainly from the left-side tract, whereas those of the caudate process portion were ramified from the right-side tract.

[Two Cases of Krukenberg Tumors That Metastasized from Gastric Cancer Treated with Multidisciplinary Therapy].

A 34-year-old woman underwent total gastrectomy with D2 lymphadenectomy for gastric cancer, and the final diagnosis was T4N3M0, Stage III C, R0. Bilateral ovarian metastases were identified 51 months later, which were removed, and the patient received S-1 plus CDDP chemotherapy. Because the patient developed pubic bone metastasis 16 months after the second operation, we continued chemotherapy using paclitaxel with bisphosphonate.

[The Clinical Role of the Neutrophil/Lymphocyte Ratio in Patients with Advanced Gastric Cancer Treated with Protein-Bound Polysaccharide K and Chemotherapy].

This study aimed to evaluate the efficacy of protein-bound polysaccharide K (PSK)-containing chemotherapy in patients with unresectable advanced or recurrent gastric cancer (AGC). We retrospectively analyzed 190 patients with AGC who received systemic chemotherapy including 69 patients who were treated with a PSK-containing regimen. Using propensity score matching, we obtained 62 matched patients in the S-1 and S-1 plus PSK groups for outcomes analysis.

Adult intussusception with cecal adenocarcinoma: Successful treatment by laparoscopy-assisted surgery following preoperative reduction.

We report a case of adult intussusception caused by cecal adenocarcinoma that was treated by laparoscopy-assisted ileocecal resection following reduction by contrast enema and preoperative colonoscopy. A 68-year-old male with cecal cancer was admitted to our hospital because of colicky abdominal pain after taking a laxative. His abdomen was distended, and a mass was palpable in the right upper quadrant, which appeared as a target- or sausage-shaped lesion by ultrasonograhpy and computed tomography.

Adult ileoileal intussusception induced by an ileal lipoma diagnosed preoperatively: report of a case and review of the literature.

We herein report a case of adult ileoileal intussusception induced by an ileal lipoma. A 68-year-old woman with a history of small intestinal tumors was admitted to our hospital with severe, colicky lower abdominal pain, similar to episodes experienced in the past. A barium meal enema at the initial admission demonstrated a small intestinal tumor in the ileum 30 cm proximal to the ileocecal valve.

Inflammatory pseudotumor of the liver: report of a case diagnosed by needle biopsy.

We report a case of a 76-year-old man with inflammatory pseudotumor, xanthogranuloma type of the liver. The patient showed clinical manifestations of a liver abscess. Abdominal sonography and computed tomography revealed an additional tumor-like lesion adjoining the liver abscess.

Breast-conservation treatment for bilateral breast cancer in five Japanese women.

Between August 1989 and September 1999, breast-conservation treatment (BCT) was performed in 250 of 256 breast cancer patients. Five of the 250 patients had bilateral breast cancer, and 4 with synchronous bilateral breast cancer of the 5 were concomitantly treated by chemo-endocrine therapy before simultaneous breast-conservation surgery for bilateral breast cancer. Chemotherapy was performed using cyclophosphamide, pirarubicin, and 5-fluorouracil, while endocrine therapy was performed using an antiestrogen agent (tamoxifen or toremifene).
