Comparative Study
A comparison of total versus partial omentectomy for advanced gastric cancer in laparoscopic gastrectomy.
Minimally invasive surgery has been slowly introduced into the field of advanced gastric cancer (AGC) surgery. However, the appropriate extent of omentectomy during laparoscopic gastrectomy for AGC is unknown. ⋯ Partial omentectomy might be an oncologically safe procedure during laparoscopic gastrectomy for serosa-negative advanced gastric cancer, similar to early gastric cancer.

Prognostic significance of XB130 expression in surgically resected pancreatic ductal adenocarcinoma.
XB130 is a newly discovered adaptor protein for intracellular signal transduction; it is involved in gene regulation, cell proliferation, cell survival, cell migration, and tumorigenesis. However, its expression and role in pancreatic ductal adenocarcinoma (PDAC) have not been investigated. The present study was designed to clarify the prognostic significance of XB130 expression in PDAC. ⋯ XB130 was overexpressed in the PDAC. XB130 is a promising pathological marker for the prediction of outcome in patients with PDAC.

Although hepatectomy is often performed with the Pringle maneuver, the problem of hepatic ischemia-reperfusion injury (HIRI) can also be serious. Thus, the present study was designed to investigate the protective effect of S-adenosylmethionine (SAMe) on HIRI, especially for patients with hepatocellular carcinoma (HCC) associated with chronic hepatitis B virus (HBV) infection and cirrhosis. ⋯ Taken together, our preliminary findings suggest that preoperative administration of SAMe is useful and safe for reducing the HIRI in partial hepatectomy, especially for HCC patients whose disease is associated with chronic HBV infection and cirrhosis.

VATS has been extensively considered as a standard method of pulmonary diagnosis and treatment of benign lung diseases. This study aimed to investigate the safety, efficacy, and feasibility of video-assisted thoracoscopic surgery (VATS) lobectomy compared with conventional lobectomy via open thoracotomy in patients with clinical early stage lung cancer. ⋯ Anatomical lobectomy was successfully completed by VATS lobectomy for lung cancer; the standard lymph node dissection was also achieved. This procedure also showed advantages in terms of surgical bleeding, duration, postoperative complications, indwelling time of chest tube, and short-term recurrence rate without significant differences from conventional lobectomy.

Although pericardial effusion (PE) is not uncommon in patients with cancer, it may lead to cardiac tamponade, a life-threatening condition. Prompt life-saving treatment is essential, and also allows the continuation of the cancer treatment. The aim of this study was to determine the prognostic factors for survival in patients with cancer who were treated surgically for PE. ⋯ Evidence of pericardial metastasis on preoperative imaging and cytopathologic confirmation that the PE and/or pericardial tissue are positive for malignant cells can be used to predict poor clinical outcomes in patients with cancer-related PE.
