Randomized Controlled Trial Multicenter Study Comparative Study
Randomized clinical study for assessment of incision characteristics and pain associated with LESS versus laparoscopic cholecystectomy.
Laparoendoscopic single-site surgery (LESS) has emerged as a technique that uses a natural scar, the umbilicus, within which a multiple-entry portal is placed into a 3.0-4.0-cm single incision to perform operations. The objective of this study was to compare incision size, wound complications, and postoperative pain of LESS compared with those of laparoscopic cholecystectomy (LC). ⋯ The LESS single-port (SP) operations demand a bigger incision than LC surgery. However, there were no differences in healing, wound infections, and hernia development. We found a tendency of less postoperative pain associated with LESS/SP than with LC.

Randomized Controlled Trial
The effects of combined epidural and general anesthesia on the autonomic nervous system and bioavailability of nitric oxide in patients undergoing laparoscopic pelvic surgery.
Pneumoperitoneum during laparoscopic surgery is known to affect visceral blood flow and result in oxidative stress. Whether epidural anesthesia will effectively reduce visceral ischemia and oxidative stress by blocking the sympathetic nervous system (SNS) during laparoscopic surgery has not been proven. ⋯ Combined epidural and general anesthesia effectively blocks SNS stimulation during laparoscopic surgery and reduces NO inactivation and oxidative stress.

Cholecystectomy is the preferred treatment option for symptomatic gallstones, but the exact relationship between cholecystectomies and symptoms still is unclear. This study aimed to assess the effectiveness of elective cholecystectomy for patients with cholecystolithiasis in terms of both persistent and de novo symptoms. ⋯ The review indicates that cholecystectomy often is ineffective with regard to persistent and de novo symptoms. The finding that the types and proportions of persistent symptoms differ from those that arise de novo suggests that this distinction may be useful in predicting which patients would and which would not benefit from a cholecystectomy.

The effect of music in the operating room is not fully understood. Through a systematic review the authors aim to give a conceptual presentation of the effect that music has on the pre- and postoperative course of surgical patients and on the effectiveness of the surgical work performed by both physicians and staff. ⋯ Music in the operating room can have beneficial effects on patients by decreasing stress, anxiety, and the demand for analgesic and anesthetic drugs. For the surgical staff, music is considered to be distracting. For the surgeon, music can increase the speed and accuracy of task performance.

Early detection and treatment of complications after laparoscopic sleeve gastrectomy (LSG) are mandatory. This study aimed to evaluate C-reactive protein (CRP), white blood cell (WBC) count, and neutrophil (NEU) count in relation to the early diagnosis of major surgical complications after LSG. ⋯ Because CRP detected leak or abscess after LSG with remarkably higher sensitivity and specificity than WBC or NEU, CRP seems to be a more accurate market for the early detection of these complications.
