Performance of EUS-FNA for mediastinal lymphadenopathy: impact on patient management and costs in low-volume EUS centers.
Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) of mediastinal lymphadenopathy has been shown to be a valuable diagnostic tool in high-volume EUS centers (≥ 50 mediastinal EUS-FNA/endoscopist/year). Our goal was to assess the diagnostic accuracy of EUS-FNA and its impact on clinical management and costs in low-volume EUS centers (<50 mediastinal EUS-FNA/endoscopist/year). ⋯ Mediastinal EUS-FNA can be performed in low-volume EUS centers without compromising diagnostic accuracy. Moreover, EUS-FNA plays an important role in the management of patients with mediastinal lymphadenopathy and reduces total diagnostic costs.

Randomized Controlled Trial
The effect of mechanical ventilation tidal volume during pneumoperitoneum on shoulder pain after a laparoscopic appendectomy.
Postlaparoscopic shoulder pain (PLSP) frequently occurs after various laparoscopic surgical procedures. Its mechanism is commonly assumed to be overstretching of the diaphragmatic muscle fibers due to the pressure of a pneumoperitoneum, which causes phrenic nerve-mediated referred pain to the shoulder. Based on this hypothesis, we speculated that during inspiration, the lung could squeeze out the phrenic nerve with carbon dioxide gas against the constantly pressurized abdominal cavity with increasing tidal volume (V(T)). Thus, we examined whether mechanical ventilation with a low V(T) (LTV, V(T) 7 ml/kg) during a pneumoperitoneum might reduce PLSP in patients undergoing laparoscopic appendectomy compared with ventilation with the traditional V(T) (TTV, V(T) 10 ml/kg). ⋯ Mechanical ventilation with a reduced 7 ml/kg V(T) during a pneumoperitoneum does not reduce the frequency and severity of PLSP after laparoscopic appendectomy compared with ventilation with the traditional V(T) (10 ml/kg).

Fast-track (FT) recovery protocols have demonstrated advantages over historical recovery routines after open colectomy; however, their impact in recovery after laparoscopic colectomy is not clearly defined. This study was designed to determine whether patients who recover on FT protocol after laparoscopic colectomy have a shorter length of stay (LOS) and fewer complications compared with patients who recover on standard (non-FT) protocol. ⋯ Fast-track recovery is independently associated with a shorter LOS and decreased morbidity after laparoscopic right hemicolectomy.

Randomized Controlled Trial Comparative Study
Different pain scores in single transumbilical incision laparoscopic cholecystectomy versus classic laparoscopic cholecystectomy: a randomized controlled trial.
The attempt to further reduce operative trauma in laparoscopic cholecystectomy has led to new techniques such as natural orifice transluminal endoscopic surgery (NOTES) and single-incision laparoscopic surgery (SILS). These new techniques are considered to be painless procedures, but no published studies investigate the possibility of different pain scores in these new techniques versus classic laparoscopic cholecystectomy. In this randomized control study, we investigated pain scores in SILS cholecystectomy versus classic laparoscopic cholecystectomy. ⋯ SILS cholecystectomy, as well as the invisible scar, has significantly lower abdominal and shoulder pain scores, especially after the first 24 h postoperatively, when this pain is nonexistent.
