Randomized Controlled Trial Multicenter Study Comparative Study
Bowel obstruction after laparoscopic and open colon resection for cancer: results of 5 years of follow-up in a randomized trial.
Postoperative bowel obstruction caused by intra-abdominal adhesions occurs after all types of abdominal surgery. It has been suggested that the laparoscopic technique should reduce the risk for adhesion formation and thus for postoperative bowel obstruction. This study was designed to compare the incidence of bowel obstruction in a randomized trial where laparoscopic and open resection for colon cancer was compared. ⋯ This analysis does not support the hypothesis that laparoscopy leads to fewer episodes of bowel obstruction compared with open surgery.

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.

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.

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.

The transrectal natural orifice transluminal endoscopic surgery (NOTES) approach is a potentially promising alternative to transgastric or transvaginal approaches for intraperitoneal procedures. However, whether the optimal transrectal approach for intraperitoneal surgery is anterior or posterior remains unknown. To evaluate this, a prospective comparison of anterior and posterior transrectal NOTES approaches in a cadaveric appendectomy model was performed. ⋯ Transrectal NOTES appendectomy is feasible in a cadaveric model using an anterior transrectal approach. This approach is technically easier, results in shorter operative times, and allows for a "pure" NOTES dissection compared with a posterior transrectal approach. Leak pressure testing of NOTES closures is unreliable in the cadaveric model.
