The vagina is the most widely used approach to natural orifice transluminal endoscopic surgery. However, a gas leak can significantly affect transvaginal operations during pneumoperitoneum laparoscopy. We tried to establish the proper technique for transvaginal appendectomy under gasless laparoscopy. ⋯ Transvaginal appendectomy with gasless laparoscopy after vaginal hysterectomy appears to be a feasible and safe modification of established techniques, with acceptable outcomes.

The psoas muscle has been shown to predict patient outcomes based on the quantification of muscle area using computed tomography (CT) scans. The accuracy of morphomic analysis on other muscles has not been clearly delineated. In this study, we determine the correlation between temporalis muscle mass, psoas muscle area, age, body mass index (BMI), and gender. ⋯ We demonstrate that dimensions of the temporalis muscle can be quantified and may serve as a proxy for age. Going forward, we aim to assess the utility of temporalis and psoas morphomics in predicting complication rates among trauma patients admitted to the hospital to predict outcomes in the future.

Comparative Study
Superiority of acetate compared with lactate in a rodent model of severe hemorrhagic shock.
Recently, we have shown that the use of lactated Ringer's (LR) solution is inferior to pure Ringer's solution (RS) in treatment of severe hemorrhagic shock in rats. The present study was performed to evaluate whether this is a specific effect of lactate or also applies to another metabolizable anion, namely acetate. ⋯ In severe hemorrhagic shock, resuscitation with both RS and NS is superior to administration of LR solution but initial outcome is even further improved if AR solution is used. Mere amelioration of the acid-base status by AR solution may explain its superior role compared with RS and NS but cannot be responsible for its superiority compared with LR solution. Here, direct injury by lactate has to be discussed.
