Hospital-level outcomes associated with laparoscopic colectomy for cancer in the minimally invasive era.
Compared to the open approach, randomized trials have shown that laparoscopic colectomy is associated with a shorter hospitalization without increases in morbidity or mortality rates. With broader adoption of laparoscopic colectomy for cancer in the USA, it is unclear if laparoscopic colectomy continues to be associated with shorter hospitalization and comparable morbidity. ⋯ Higher laparoscopy rates were associated with only slightly lower postoperative morbidity rates and modestly shorter hospitalizations.

Parenchyma-sparing resections for pancreatic neuroendocrine tumors.
Parenchyma-sparing pancreatectomy (PSP), including enucleation and central pancreatectomy, has been investigated as an alternative to standard resection for pancreatic endocrine neoplasm, but the benefit/risk of these procedures remains little known. ⋯ In selected patients, with small and low-grade tumors, PSP are associated with excellent overall and recurrence-free survivals. These procedures are associated with an increased postoperative morbidity but an excellent postoperative pancreatic function. Therefore, they should be considered as a valid therapeutic option in selected well-differentiated pancreatic neuroendocrine tumors.

Comparative StudyArtificial neural network model for predicting 5-year mortality after surgery for hepatocellular carcinoma: a nationwide study.
To validate the use of artificial neural network (ANN) models for predicting 5-year mortality in HCC and to compare their predictive capability with that of logistic regression (LR) models. ⋯ In comparison with the conventional LR model, the ANN model in this study was more accurate in predicting 5-year mortality. Further studies of this model may consider the effect of a more detailed database that includes complications and clinical examination findings as well as more detailed outcome data.
