The aim of this study was to evaluate the utility of staging laparoscopy in patients with biliary cancers in the era of modern diagnostic imaging. ⋯ Staging laparoscopy ensured that unnecessary laparotomy was not performed in 36% of patients with potentially resectable biliary carcinoma after extensive preoperative imaging. In patients with biliary carcinoma that appears resectable, staging laparoscopy allows detection of peritoneal and liver metastasis in one third of patients. Both vascular and lymph nodes invasions were not diagnosed by this procedure. Due to these limitations, laparoscopy is more useful in ruling out dissemination in GBC and IHC than in HC.

The McGill Inanimate System for Training and Evaluation of Laparoscopic Skills (MISTELS) is a series of five tasks with an objective scoring system. The purpose of this study was to estimate the interrater and test-retest reliability of the MISTELS metrics and to assess their internal consistency. ⋯ The MISTELS metrics have excellent reliability, which exceeds the threshold level of 0.8 required for high-stakes evaluations. These findings support the use of MISTELS for evaluation in many different settings, including residency training programs.

Comparative Study
Modified needlescopic video-assisted thoracic surgery for primary spontaneous pneumothorax : the long-term effects of apical pleurectomy versus pleural abrasion.
The objective of this study was to evaluate the feasibility and safety of modified needlescopic video-assisted thoracic surgery (VATS) for treating primary spontaneous pneumothorax. The efficacy between apical pleurectomy and pleural abrasion through this technique was also compared. ⋯ Modified needlescopic VATS provides a feasible and safe procedure for treating primary spontaneous pneumothorax. In terms of efficacy, apical pleurectomy is more effective in preventing ipsilateral recurrence than pleural abrasion.
