Although intracorporeal anastomosis has been demonstrated to be safe and effective after right colectomy, limited data are available about its efficacy after left colectomy for colon cancer located in splenic flexure. A multi-institutional audit was designed, including 92 patients who underwent laparoscopic left colectomy with intracorporeal anastomosis (IA) compared with 89 matched patients who underwent a laparoscopic left colectomy with extracorporeal anastomosis (EA). There was no significant difference in terms of age, sex, BMI, and ASA score between the two groups...

Gamma-herpesviruses infect lymphocytes and cause lymphocytic cancers. Murid Herpesvirus-4 (MuHV-4), Epstein-Barr virus and the Kaposi's Sarcoma-associated Herpesvirus all infect B cells. Latent infection can spread by B cell recirculation and proliferation, but whether this alone achieves systemic infection is unclear. To test the need of MuHV-4 for lytic infection in B cells we flanked its essential ORF50 lytic transactivator with loxP sites, then infected mice with B cell-specific cre expression (CD19-cre)...

Purpose: Laparoscopic gastrectomy is accepted as a standard treatment for patients with early gastric cancer in Korea, Japan, and China. However, duodenal stump leakage remains a fatal complication after gastrectomy. We conducted a prospective phase II study to evaluate the safety of the new technique of laparoscopic reinforcement suture (LARS) on the duodenal stump. Materials and Methods: The estimated number of patients required for this study was 100 for a period of 18 months...

Splenic marginal zone lymphomas (SMZLs) are rare indolent B cell neoplasms that affect the spleen, bone marrow, and blood. Although they have an indolent course in the majority of patients, who have a median survival of 8-10 years, ∼ 30% may experience a worse outcome. The prognostic criteria of progression are lymph node and extra-nodal involvement, high lymphocyte counts, anaemia, and thrombocytopenia. The treatment of SMZLs include a "wait and watch strategy", splenectomy, and alkylating agents ± rituximab...

It is often difficult to control perioperative bleeding in patients with liver cirrhosis and concurrent thrombocytopenia and coagulation factor deficiency. Partial splenic embolization (PSE), an auxiliary treatment strategy in management of liver cirrhosis and hepatocellular carcinoma, can not only increase platelets but also improve liver function. With advances in interventional radiology, PSE is a safer and more reliable procedure compared to a splenectomy. We present the case of a 69-year-old man diagnosed with left lung cancer, with thrombocytopenia, and hepatitis C virus-related cirrhosis...

Canine nodal marginal zone lymphoma (nMZL) is classified as an indolent lymphoma. Such lymphomas are typified by low mitotic rate and slow clinical progression. While the clinical behaviour of canine splenic MZL has been described, characterized by an indolent course and a good prognosis following splenectomy, there are no studies specifically describing nMZL. The aim of this study was to describe the clinical features of and outcome for canine nMZL. Dogs with histologically confirmed nMZL undergoing a complete staging work-up (including blood analysis, flow cytometry [FC] on lymph node [LN], peripheral blood and bone marrow, imaging, histology and immunohistochemistry on a surgically removed peripheral LN) were retrospectively enrolled...

A comprehensive immunogenicity scheme is proposed to examine immune response of bovine sourced hemostasis collagen sponge to establish foundation for further researches and decrease the incidence of adverse reaction in clinical trials. Compared with negative control group without any implant, spleen and lymph nodes morphology show no apparent swelling in mice with different doses of collagen sponge implants. Immune cells population, especially lymph nodes cells population, is practically coincident with organs...

BACKGROUND: For left-sided pancreatic ductal adenocarcinoma (PDAC), radical antegrade modular pancreatosplenectomy (RAMPS) is a reasonable surgical approach for tumor-free margin resection and systemic lymph node clearance. In pancreaticoduodenectomy for PDAC, the superior mesenteric artery (SMA)-first approach (or the "artery-first approach") has become the standard procedure. With improvements in laparoscopic instruments and techniques, some surgeons attempted to apply laparoscopic RAMPS (L-RAMPS) for carefully selected patients with left-sided PDAC...

Background: Level of proximal lymphovascular ligation remains controversial in carcinoma rectum. High-tie inferior mesenteric artery (IMA) claims better lymph node clearance; low-tie IMA minimizes autonomic nerve injury (ANI) and ensures vascularity to anastomosis. Objective of this study is to compare postsurgical complications and oncological clearance in laparoscopic rectal resection (LRR) and open rectal resection (ORR) for carcinoma rectum, with low-tie IMA and selective D3 lymphadenectomy...

Patients with HIV are susceptible to mycobacterium infection. In the case of fast-growing mycobacteria, the group to which Mycobacterium fortuitum (M. fortuitum) belongs, infections have been described in the skin, lungs, lymph nodes and disseminated disease. We present the case of a 43-year-old male patient with pre-diagnosis of HIV in antiretroviral therapy, which comes as a fever, asthenia, weight loss and chronic diarrhea. Abdominal tomography is performed and hepatosplenomegaly is evidenced with nodular lesions in the spleen...

Background: Impact of splenic hilar LN dissection during total gastrectomy for proximal advanced gastric cancer is controversial. The objective of this study was to assess the impact on prognosis of splenic hilar lymph node(LN) metastasis compared to that of metastasis to other regional LN groups. Study Design: Patients who underwent total gastrectomy with D2 LN dissection from 2000 to 2010 were reviewed retrospectively. The clinicopathologic characteristics and long-term results of patients with splenic hilar LN metastasis were compared to those of patients with only metastasis to other extraperigastric LNs (stations #8a, #9, #11, or #12a)...

Approximately two-thirds of patients with neuroblastoma are found to have metastatic disease at time of diagnosis with frequent skeletal, lymph node, central nervous system, and liver involvement. Using a serial in vivo splenic injection model, we have isolated an aggressive subclone (BE(2)-C/LM2) from MYCN-amplified neuroblastomas that demonstrate an enhanced propensity to develop metastatic liver lesions. BE(2)-C/LM2 subclone cells demonstrate increased adherent, soft agar colony and tumorsphere growth in vitro...

BACKGROUND: The therapeutic efficacy of dissection of the splenic hilar lymph nodes (#10) has not been fully evaluated in locally advanced proximal gastric cancer (LAGC) invading the greater curvature of the stomach. METHODS: Patients with LAGC invading the greater curvature who underwent D2 total gastrectomy with splenectomy between January 2000 and May 2015 were retrospectively examined. The therapeutic value index was calculated by multiplying the metastatic rate of a station and the 5-year survival of patients with metastasis to that station; the metastatic rate and the index of each lymph node station were then compared...
