Surgical wound management made easier and more cost-effective.

Evidence-based guidelines for the prevention of surgical site infection (SSI) have been published by the U.S. Centers for Disease Control and Prevention (CDC).

Novel therapeutic targets for sepsis: regulation of exaggerated inflammatory responses.

Sepsis is a devastating and complex syndrome and continues to be a major cause of morbidity and mortality among critically ill patients at the surgical intensive care unit setting in the United States. The occurrence of sepsis and septic shock has increased significantly over the past two decades. Despite of highly dedicated basic research and numerous clinical trials, remarkable progress has not been made in the development of novel and effective therapeutics.

Prosthetic repair of an incarcerated groin hernia with small intestinal resection.

Purpose: No consensus has been reached on the use of prostheses in a potentially infected operating field. In this study, we evaluated the validity of a mesh prosthesis for the repair of incarcerated groin hernias with intestinal resection.

Methods: Twenty-seven patients underwent operations for correction of incarcerated groin hernias with small intestinal resection at our hospital between January 2000 and March 2010.

[Evaluation of S-1 for stage IV gastric cancer].

To evaluate the efficacy of S-1 for Stage IV gastric cancer, we retrospectively examined 124 patients with Stage IV gastric cancer. We classified patients into two groups based on the presence or absence of S-1 administration: the S-1 therapy group (n= 56) and the non-S-1 therapy group (n=68). Basically, patients received S-1 orally at 40 mg per square meter of body surface area twice daily for 4 weeks, followed by 2 weeks without chemotherapy.

Evaluation of sentinel lymph node biopsy in clinically node-negative breast cancer.

Background: In patients with clinically node-negative breast cancer, diagnosed with palpation and several types of imaging examination, sentinel lymph nodes accurately predict the status of the other axillary nodes, which determine the nature of subsequent adjuvant treatment. In addition, compared with axillary lymph node dissection, sentinel-node biopsy results in less postoperative morbidity, including pain, numbness, swelling, and reduced mobility in the ipsilateral arm.

Methods: We analyzed the validity of the sentinel node biopsy procedure using dual-agent injection of blue dye and radioactive colloid performed in our hospital from May 2006 through March 2010.

[Effects of irinotecan and 5-FU combination therapy in gastric cancer--is combination therapy synergic?].

Unlabelled: The response rate of Irinotecan for gastric cancer is reported to be 18. 4%. The rate is improved by combination with 5-FU.

HPV infection in an HIV-positive patient with primary squamous cell carcinoma of rectum.

Primary squamous cell carcinoma (SCC) of the colorectum is a rare malignancy of unknown etiology and pathogenesis. We report a case of primary SCC of the rectum. A 55-year-old man with a rectal tumor and human immunodeficiency virus (HIV) infection was referred to our hospital.

A case of a mesenteric cyst in the sigmoid colon of a 3-year-old girl.

Mesenteric cysts are rare. In this paper we present a case of a mesenteric cyst in the sigmoid colon of a 3-year-old girl. On the first visit to our department, a smooth-surfaced soft mass approximately 15 cm in diameter was noticed in the right lower abdomen.

Liver cyst with biliary communication successfully treated with laparoscopic deroofing: a case report.

A 56-year-old woman visited our hospital because of high fever and right hypochondralgia. Abdominal computed tomography showed a liver cyst 10 cm in diameter and dilatation of the intrahepatic bile duct. Percutaneous transhepatic drainage of the cyst guided by ultrasonography disclosed that the cyst contained a brown milky fluid, and cystography showed biliary communication.

Preoperative plasma adiponectin level is a risk factor for postoperative infection following colorectal cancer surgery.

Background: Adiponectin is produced exclusively by adipose tissues. It is associated with visceral adiposity and various metabolic disorders, and acts as an anti-inflammatory protein that inhibits nuclear factor-kappaB activation. The purpose of this study is to clarify the association between the preoperative plasma adiponectin levels and the development of postoperative infection following colorectal cancer surgery.

A case of an intramesosigmoid hernia.

We report an extremely rare case of an intramesosigmoid hernia with small bowel herniation in a defect on the right (medial) leaf of the mesosigmoid. A 46-year-old man was admitted to the hospital complaining of lower abdominal pain, nausea, and vomiting for 6 days. He had undergone an operation for a right inguinal hernia and an appendectomy during childhood.

An analysis of factors that influence the duration of suction drainage in breast cancer surgery.

Background: The duration of suction drainage in patients undergoing breast cancer surgery is difficult to predict. The uncertainty this poses may complicate the development of a clinical pathway for patients with breast cancer. In this study we attempted to identify factors that may influence the duration of suction drainage in patients undergoing breast cancer surgery.

Seromuscular tear of the sigmoid colon in the absence of trauma: a case report.

A 16-year-old adolescent boy was admitted to our hospital with severe lower abdominal pain and was found to have peritonitis, probably caused by acute appendicitis. At laparotomy, we found a paper-thin, dilated sigmoid colon; the seromuscular layer on the antimesenteric side was torn, and the untorn mucosa showed a pinpoint perforation. The seromuscular defect had spread circumferentially to involve the entire circumference of the colon wall.

Case of adenosquamous carcinoma of the ascending colon.

Adenocarcinoma accounts for most of the malignant tumors originating from the colon, whereas adenosquamous carcinoma is rare, accounting for about 0.1% of all colon cancers. We present herein a case of adenosquamous carcinoma of the ascending colon.

Case of meningeal carcinomatosis with gastric cancer which manifested meningeal signs as the initial symptom; the palliative benefit of radiotherapy.

A 53-year-old male presenting with anorexia, intermittent diplopia, general fatigue, headache and vertigo was admitted to our hospital. He was diagnosed as having gastric cancer by endoscopy of his upper gastrointestinal tract. Brain computed tomography (CT) showed no abnormalities, but magnetic resonance imaging (MRI) showed slight enhancement in the cerebellar sulcus.

Case of an inflammatory fibroid polyp of the cecum.

An inflammatory fibroid polyp (IFP) is a rare benign lesion, originating in the submucosa of the gastrointestinal tract. It is histopathologically characterized by distinctively arranged fibrous connective tissue and blood vessels with inflammatory cell infiltration. It typically arises in the stomach and small intestine but also arises infrequently in the colon.

Male choriocarcinoma with metastasis to the jejunum: a case report and review of the literature.

We report on a patient with male choriocarcinoma. The patient was a 31-year-old male patient with jejunal choriocarcinoma that metastasized from the mediastinum. He was admitted complaining of melena and severe anemia.

[Antitumor effect of paclitaxel for gastric cancer is AUC dependent].

Paclitaxel (PTX), which is used for ovarian cancer, lung cancer, breast cancer and gastric cancer, is administered at a dose of 210 mg/m(2) once every three weeks. However, WHO grade 3-4 hematological and non-hematological toxicity occurred frequently in this manner. In recent studies about ovarian cancer and lung cancer, a schedule in which PTX was given weekly could have the same or better efficacy, with fewer side effects.

An improvement in the quality of life after performing endoscopic balloon dilation for postoperative anastomotic stricture of the rectum.

A 55-year-old woman underwent a low anterior resection for rectal cancer 7 years earlier at a different hospital. Thereafter, she often had such symptoms as abdominal pain, frequent bowel movements, and constipation. We considered postoperative bowel adhesion to be the cause of these symptoms, and a laparoscopic adhesiotomy was therefore performed twice.

Mild hemophilia A diagnosed in a 55-year-old patient after pancreatoduodenectomy for carcinoma of the papilla of vater.

Hemophilia A is a sex-linked hereditary disease, and the total number of patients with this condition is small. It is quite rare for general surgeons to encounter a patient with hemophilia A. Moreover, it is extremely rare for surgeons to encounter adult patients with undiagnosed hemophilia.

[A case of elderly metastatic breast cancer with a complete response to treatment with capecitabine and cyclophosphamide].

We report a case of elderly metastatic breast cancer with a complete response to the treatment with XC (X: capecitabine and C: cyclophosphamide). A 78-year-old woman, who presented with left breast cancer, underwent pectoralis-preserving mastectomy when she was 76 years old. Pathological findings were as follows: invasive ductal carcinoma (scirrhous type), pT1c (2.

Does impaired TH1/TH2 balance cause postoperative infectious complications in colorectal cancer surgery?

Background: Recent studies have shown that the Th1/Th2 balance shifts toward Th2 dominance in cancer-bearing state or under surgical stress. This study was designed to investigate whether perioperative impaired Th1/Th2 balance is associated with the occurrence of postoperative infection following colorectal cancer surgery.

Methods: From 53 patients with colorectal cancer, peripheral blood samples were collected, before surgery, and on the 3rd, 7th, and 14th postoperative days.

Identification of neovasculature using nestin in colorectal cancer.

CD34 is commonly used as an endothelial cell marker of tumor vessels. However, this marker detects not only newly formed, but also pre-existing large blood vessels. Nestin, a class VI intermediate filament protein, has recently received attention as a marker for detecting newly formed endothelial cells.
