In the morbidly obese population that undergoes bariatric surgery, venous thromboembolism (VTE) is the leading cause of morbidity and mortality. Certain factors place a patient at higher risk for VTE. No consensus exists on VTE screening or prophylaxis for the high-risk patient. This report describes the results of a survey on VTE screening and prophylaxis patterns in high-risk bariatric surgery. ⋯ This study describes current practice patterns of VTE screening and prophylaxis in high-risk bariatric surgery. Nearly all surgeons agree on risk factors that qualify patients as high risk, but only half routinely screen patients preoperatively. Preoperative VTE chemoprophylaxis is used by nearly all surgeons, but the duration of therapy varies. Use of IVC filters is not routine, and postoperative screening was performed by less than half of the respondents. An understanding of current practice patterns yields insight into the rates of VTE and shows variability in the need for evidence-based prophylaxis and standardized screening.

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.

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.

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.
