[Two cases of esophageal variceal rupture associated with chemotherapy for liver metastasis of breast cancer].

A morphological change resembling liver cirrhosis called pseudocirrhosis may be observed following chemotherapy for liver metastasis of breast cancer. Pseudocirrhosis is hypothesized to be caused by retraction of the hepatic capsule along with tumor shrinkage and subsequent scar formation around the metastatic lesion, as a response to the infiltrating tumor or chemotherapy-induced hepatic injury. The progression of cirrhotic changes may result in portal hypertension and esophageal varices.

Meta-analysis of the results of randomized controlled trials that compared laparoscopic and open surgery for acute appendicitis.

Purpose: We conducted a meta-analysis to evaluate and compare the outcomes of laparoscopic and open surgery for the treatment of patients with acute appendicitis.

Methods: We searched MEDLINE, EMBASE, Science Citation Index, and the Cochrane Controlled Trial Register for relevant papers published between January 1990 and February 2012. We analyzed 22 outcomes of laparoscopic and open surgery for acute appendicitis.

A meta-analysis of the short- and long-term results of randomized controlled trials that compared laparoscopy-assisted and open colectomy for colon cancer.

Purpose: We conducted a meta-analysis to evaluate and compare the short- and long-term results of laparoscopy-assisted colectomy (LAC) and open colectomy (OC) for colon cancer.

Methods: We searched MEDLINE, EMBASE, Science Citation Index, and Cochrane Controlled Trial Register for relevant papers published between January 1990 and October 2011 by using the search terms "laparoscopy," "laparoscopy-assisted," "surgery," "colectomy," "colon cancer," and "randomized clinical trials (RCTs)". We analyzed the outcomes of each type of surgery over short- and long-term periods.

A meta-analysis of the short- and long-term results of randomized controlled trials that compared laparoscopy-assisted and conventional open surgery for colorectal cancer.

Purpose: We conducted a meta-analysis to evaluate and compare the short- and long-term results of laparoscopic colorectal surgery (LCRS) and conventional open surgery (OCRS) for colorectal cancer (CRC).

Methods: We searched relevant papers published between January 1990 and May 2011. We analyzed the outcomes of each type of surgery over the short- and long-term periods.

Comparison of the outcomes between anatomical resection and limited resection for single hepatocellular carcinomas no larger than 5 cm in diameter: a single-center study.

Background/purpose: Liver resection is a widely preferred treatment modality for hepatocellular carcinomas (HCCs). This study aimed to compare the survival impact of anatomical resection with that of limited resection, in patients with single HCCs no larger than 5 cm in diameter.

Methods: A cohort study was carried out on 209 consecutive patients who underwent hepatic resection for a single HCC no larger than 5 cm in diameter between January 1994 and March 2007 at Osaka City General Hospital.

Efficacy and toxicity of fluorouracil, leucovorin plus oxaliplatin (FOLFOX4 and modified FOLFOX6) followed by fluorouracil, leucovorin plus irinotecan(FOLFIRI)for advanced or metastatic colorectal cancer--case studies.

Aim: In this study, we investigated the efficacy and toxicity of fluorouracil(FU)+Leucovorin(LV)with oxaliplatin (FOLFOX)and irinotecan(FOLFIRI)for patients with advanced or metastatic colorectal cancer.

Methods: Eleven patients with advanced or metastatic colorectal cancer underwent chemotherapy, such as FOLFOX4, mFOLFOX6, and FOLFIRI. Four and 7 patients underwent FOLFOX4 and mFOLFOX6 as a first-line therapy, respectively.

[A case of advanced gastric cancer with pulmonary carcinomatous lymphangitis and paraaortic lymph node metastases responding to combination chemotherapy of S-1 and irinotecan(CPT-11)].

A 70-year-old woman with pulmonary carcinomatous lymphangitis and paraaortic lymph node metastases due to gastric cancer, was treated by combination chemotherapy of S-1 and irinotecan (CPT-11). After one course of the chemotherapy, pulmonary carcinomatous lymphangitis and paraaortic lymph node metastases were remarkably improved. Diet intake was improving and cancer pain remarkably declined.

A case of solid neuroendocrine carcinoma of the breast in a 40-year-old woman.

We report a case of neuroendocrine carcinoma in a 40-year-old woman who presented with two lumps in her left breast. Mammography failed to reveal any lesions because she had so-called dense breasts, but ultrasonography showed 4 irregular hypoechoic masses. Magnetic resonance imaging also showed 4 homogeneous lobulated tumors with early contrast enhancement, suggesting malignancy.

Endoscopic stenting versus surgical gastroenterostomy for palliation of malignant gastroduodenal obstruction: a meta-analysis.

Background: We attempted to elucidate the current status of endoscopic self-expanding metal stents for palliation of malignant gastroduodenal obstruction in comparison with surgical gastroenterostomy.

Methods: Original articles and abstracts published from January 1990 to September 2006 were searched in Medline, EMBASE, and Cochrane Controlled Trials Register databases. Clinical appraisal and data extraction were independently conducted by two reviewers.

Internal hernia with strangulation through a mesenteric defect after laparoscopy-assisted transverse colectomy: report of a case.

A 58-year-old woman underwent laparoscopy-assisted transverse colectomy for transverse colon cancer. On postoperative day 7, she experienced sudden abdominal pain accompanied by vomiting and fever. Computed tomography showed a small bowel obstruction caused by an internal hernia.

Meta-analysis of short-term outcomes after laparoscopy-assisted distal gastrectomy.

Aim: To elucidate the current status of laparoscopy-assisted distal gastrectomy (LADG) with regard to its short-term outcomes by comparing it with conventional open distal gastrectomy (CODG).

Methods: Original articles published from January 1991 to August 2006 were searched in the MEDLINE, EMBASE, and Cochrane Controlled Trials Register. Clinical appraisal and data extraction were conducted independently by 2 reviewers.

Three-dimensional computed tomography in laparoscopic surgery for colorectal carcinoma.

Aim: To evaluate the usefulness of three-dimensional computed tomography (3DCT) in laparoscopic surgery for colorectal carcinoma.

Methods: Seventy-two patients with colorectal cancer who underwent curative operation at our hospital were enrolled in this study. They were classified into two groups by operative procedures.

Efficacy of multislice computed tomography for gastroenteric and hepatic surgeries.

Aim: To determine the efficacy of multislice CT for gastroenteric and hepatic surgery.

Methods: Dual-phase helical computed tomography was performed in 50 of 51 patients who underwent gastroenteric and hepatic surgeries. Twenty-eight, eighteen and four patients suffering from colorectal cancer, gastric cancer, and liver cancer respectively underwent colorectal surgery (laparoscopic surgery: 6 cases), gastrectomy, and hepatectomy.
