Introduction: One of the main adverse outcomes following Holmium laser enucleation of the prostate (HoLEP) is the development of transient de novo urinary incontinence (UI). We aimed to evaluate the correlation of multiple risk factors to UI rates post‐HoLEP. Methods: A review of prospectively maintained 7 year database for HoLEP patients in a single center was performed. UI data at 6 week, 3 month, and 1 year follow‐up intervals were assessed with bivariate and multivariate analysis of multiple potential risk factors. Results: The study included 666 patients with median (IQR) age of 72 (66–78) years old and median (IQR) preoperative prostate volume of 89 (68–126) gm. UI was seen in 287 (43%), 100 (15%) and 26 (5.8%) at 6 week, 3 month, and 1 year follow up occasions respectively. At 6 weeks follow up, UI type was stress, urge and mixed in 121 (18.16%), 118 (17.72) and 48 (7.21%) patients respectively. Using a multivariate regression analysis, obesity and pre‐operative UI were associated with postoperative UI rate at both 6 week (p =.0065,.031) and 3 month (p =.0261,.044) follow up encounters respectively. Also, larger specimen weight was another predictor for 6 week UI (p =.0399) while higher frailty score was a predictor for UI at 3 month occasion (p =.041). Conclusion: Patients with preoperative UI, obesity, frailty, and large prostate volume are at higher risk of short‐term UI post‐HoLEP up to 3 months. Patients with one or more of these risk factors should be counseled regarding the higher risk of UI. [ABSTRACT FROM AUTHOR]

Background: Surgical site infection (SSI) remains a persistent and morbid problem in colorectal surgery. Key to its pathogenesis is the degree of intraoperative bacterial contamination at the surgical site. The purpose of this study was to evaluate a novel wound retractor at reducing bacterial contamination.Methods: A prospective multicenter pilot study utilizing a novel wound retractor combining continuous irrigation and barrier protection was conducted in patients undergoing elective colorectal resections. Culture swabs were collected from the incision edge prior to device placement and from the exposed and protected incision edge prior to device removal. The primary and secondary endpoints were the rate of enteric and overall bacterial contamination on the exposed incision edge as compared to the protected incision edge, respectively. The safety endpoint was the absence of serious device-related adverse events.Results: A total of 86 patients were eligible for analysis. The novel wound retractor was associated with a 66% reduction in overall bacterial contamination at the protected incision edge compared to the exposed incision edge (11.9 vs. 34.5%, P < 0.001), and 71% reduction in enteric bacterial contamination (9.5% vs. 33.3%, P < 0.001). The incisional SSI rate was 2.3% in the primary analysis and 1.2% in those that completed the protocol. There were no adverse events attributed to device use.Conclusions: A novel wound retractor combining continuous irrigation and barrier protection was associated with a significant reduction in bacterial contamination. Improved methods to counteract wound contamination represent a promising strategy for SSI prevention (NCT 02413879). [ABSTRACT FROM AUTHOR]

Lower limb ischemia in diabetic patients is a result of macro- and microcirculation dysfunction. Diabetic patients undergoing limb amputation carry high mortality and morbidity rates, and decision making concerning the level of amputation is critical. Aim of this study is to evaluate a novel microdialysis technique to monitor tissue microcirculation preoperatively and predict the success of limb amputation in such patients. Overall, 165 patients with type 2 diabetes mellitus undergoing lower limb amputation were enrolled. A microdialysis catheter was placed preoperatively at the level of the intended flap for the stump reconstruction, and the levels of glucose, glycerol, lactate and pyruvate were measured for 24 consecutive hours. Patients were then amputated and monitored for 30 days regarding the outcome of amputation. Failure of amputation was defined as delayed healing or stump ischemia. Patients were divided into two groups based on the success of amputation. There was no difference between the two groups regarding gender, ASA score, body mass index, comorbidities, diagnostic modality used, level of amputation, as well as glucose, glycerol, and pyruvate levels. However, local concentrations of lactate were significantly different between the two groups and lactate/pyruvate (L/P) ratio was independently associated with failed amputation (threshold defined at 25.35). Elevated preoperative tissue L/P ratio is independently associated with worse outcomes in diabetic patients undergoing limb amputation. Therefore, preoperative tissue L/P ratio could be used as a predicting tool for limb amputation's outcome, although more clinical data are needed to provide safer conclusions. [ABSTRACT FROM AUTHOR]

Midgut malrotation most commonly presents in young children. This diagnosis is not often entertained in the adolescent or adult with abdominal complaints. We reviewed our experience with this subset of malrotation patients. A retrospective review of medical records from adolescent or adult patients identified with a diagnosis of anomaly of intestinal fixation or malrotation, who were treated within our health system between 1993 and 2004. A total of 33 patients were diagnosed with malrotation and treated with Ladd’s procedure. Acute abdominal pain was present in 50%, and chronic complaints were present in the other patients. Initial work-up included computed tomography (CT) scan (28%), upper gastrointestinal (UGI) study (38%), and plain films (47%) Postoperative complications occurred more frequently in patients that were operated on emergently (60%) than in those that underwent elective surgery (22%; p = 0.04). This large case series of intestinal malrotation in the nonpediatric age group suggests that Ladd’s procedure can be performed very safely. Moreover, the results suggest that patients with known malrotation should have Ladd’s procedure performed electively rather than urgently. [ABSTRACT FROM AUTHOR]
