Predictive Factors for Lymph Node Metastasis and Prognostic Factors for Survival in Rectal Neuroendocrine Tumors.
Neuroendocrine tumors have malignant potential, and lymph node metastasis can occur. This study aimed to identify predictive factors of lymph node metastasis and prognostic factors for survival in rectal neuroendocrine tumors. ⋯ Tumor grade combined with tumor size is an important predictive factor for lymph node metastasis and could serve as a prognostic factor for survival outcomes.

Drain Placement Does Not Increase Infectious Complications After Retromuscular Ventral Hernia Repair with Synthetic Mesh: an AHSQC Analysis.
The use of surgical drains after ventral hernia repair (VHR) remains controversial. Some have concerns of increased infectious complications; others advocate that drains reduce fluid accumulation and surgical site occurrences (SSO). The aim of our study was to investigate the impact of retromuscular drains on SSO following retromuscular VHR with synthetic mesh. ⋯ Drain placement after retromuscular VHR with synthetic mesh is a common practice. Based on an analysis of early outcomes, surgical drains do not increase the risk of surgical infectious complications, and may be protective against some SSOs, such as seroma formation.

Neuroendocrine Liver Metastasis: Prognostic Implications of Primary Tumor Site on Patients Undergoing Curative Intent Liver Surgery.
Neuroendocrine tumors typically arise from pancreatic (PNET) vs. gastrointestinal or thoracic origins (non-PNET). The impact of primary tumor site on long-term prognosis following resection of neuroendocrine liver metastasis (NELM) remains poorly defined. The objective of the current study was to define the association of primary tumor location on prognosis of patients undergoing curative intent liver resection for NELM. ⋯ PNET patients more often present with non-functional NELM and moderately differentiated tumors. On propensity-matched analysis, factors such as extrahepatic disease and tumor grade, but not primary tumor location, were associated with prognosis of patients undergoing curative intent liver surgery for NELM.
