Published studies evaluating the effect of robotic assistance on clinical outcomes and costs of care in diaphragmatic hernia repair (DHR) have been limited. ⋯ Laparoscopic DHR is the most cost-effective approach to DHR. Robotic assistance provides clinical outcomes comparable with laparoscopic DHR, but is associated with increased index cost.

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive malignancy with predilection for peritoneal dissemination. Accurate peritoneal staging is imperative for treatment recommendations, as one-third of patients develop peritoneal recurrence after resection. Because >90% of PDAC tumors harbor mutant KRAS (mKRAS), we sought to determine feasibility of mKRAS DNA detection in peritoneal lavage (PL) fluid using droplet-digital polymerase chain reaction (ddPCR) via a prospective trial. ⋯ This prospective study establishes the feasibility of PL mKRAS detection. Clinically positive disease was identified in 1 in 4 staging laparoscopies. Although PL mKRAS was highly associated with clinically positive findings, many clinically negative laparoscopies had detectable PL mKRAS, suggesting that standard staging may be inadequate. Longer follow-up will elucidate utility of this promising molecular assay.

Conventional philosophy promotes the second trimester as the ideal time during pregnancy for cholecystectomy. However, literature supporting this belief is sparse. The purpose of this study is to examine the association of trimester and clinical outcomes after cholecystectomy during pregnancy. ⋯ Our results suggest that cholecystectomy can be performed in the first trimester without significantly increased risk of maternal and fetal complications, compared to the second trimester. In contrast, cholecystectomy during pregnancy should not be delayed until the third trimester.
