Randomized Controlled Trial Multicenter Study
Carbon dioxide insufflation during endoscopic retrograde cholangiopancreatography reduces bowel gas volume but does not affect visual analogue scale scores of suffering: a prospective, double-blind, randomized, controlled trial.
Endoscopic retrograde cholangiopancreatography (ERCP) and related procedures can cause abdominal pain and discomfort. Two clinical trials have indicated, using the visual analogue scale (VAS) score, that CO(2) insufflation during ERCP ameliorates the suffering of patients without complications, compared with air insufflation. However, differences in patient suffering between CO(2) and air insufflation after ERCP under deep conscious sedation have not been reported. We focused on the gas volume score (GVS) as an objective indicator of gas volume, and designed a multicenter, prospective, double-blind, randomized, controlled study with CO(2) and air insufflation during ERCP. ⋯ CO(2) insufflation during ERCP reduces GVS (bowel gas volume) but not the VAS score of suffering compared with air insufflation. Deep and sufficient sedation during ERCP and related procedures is important for the palliation of patients' pain and discomfort.

Randomized Controlled Trial
Efficacy of turmeric (curcumin) in pain and postoperative fatigue after laparoscopic cholecystectomy: a double-blind, randomized placebo-controlled study.
Better patient-reported outcomes (PROs) of laparoscopic cholecystectomy (LC) are premised upon PROs such as postoperative pain and fatigue. These PROs are indices of convalescence and return to normal activity. Curcumin (turmeric) is used in India for traumatic pain and fatigue for its anti-inflammatory/antioxidant and tissue modulation/healing properties. We studied the effect of curcumin on pain and postoperative fatigue in patients of LC. ⋯ Turmeric (curcumin) improves postoperative pain- and fatigue-related PROs following LC.

Randomized Controlled Trial Comparative Study
Effect of training and instrument type on performance in single-incision laparoscopy: results of a randomized comparison using a surgical simulator.
Single-incision laparoscopy (SIL) is potentially less invasive compared with standard laparoscopic surgery (LAP); however, it may be more technically challenging and have a longer learning curve. A two-phase study was conducted to examine the performance of standardized tasks on a surgical simulator by novices during a distributed training period. Phase 1 examined the effect of LAP-specific or SIL-specific training on skill acquisition for both techniques. Phase 2 compared the effectiveness and learning curves of additional instrument types for SIL (straight [STR] vs. dynamic articulating [D-ART]). ⋯ LAP technique results in superior task performance with a shorter learning curve compared with SIL technique during a standardized training period. SIL-specific simulator training is better than LAP training alone to improve SIL performance. Neither S-ART nor D-ART instruments for SIL are associated with improved performance or shorter learning curve compared with STR instruments.

Previous studies have shown different pain characteristics in different types of laparoscopic operations, but pain pattern has not been studied in detail after laparoscopic inguinal hernia repair. To optimise preoperative patient information and postoperative analgesic treatment the present study investigated postoperative pain in terms of time course, pain intensity and individual pain components during the first 4 days after transabdominal preperitoneal hernia repair (TAPP). ⋯ Pain was most intense 3 h after the operation and declined to low levels within the first 3 days. Visceral pain was by far the dominating pain component compared with incisional and shoulder pain.

The aim of the study is to describe techniques of robot-assisted parenchymal-sparing liver surgery. ⋯ Robot assistance allows optimal access to all liver segments and facilitates parenchymal-sparing surgery also for lesions located in the posterosuperior segments or in contact with main liver vessels.
