Robotic surgery (RS) has been increasingly incorporated into colorectal surgery (CRS) training. The degree to which RS has been integrated into CRS residency training is not well described. A web-based survey was sent to all 2019 accredited CRS residency programs within the United States and Canada. Program directors (PDs) were queried on how robotic surgery had been integrated into their program, specifics on RS curriculum and opinions on RS training during general surgery residency. We compared survey responses by program type (university-based, university-affiliated programs, or independent programs) and by geographic region. In addition, a chi-square test was used to evaluate differences in survey responses with respect to robotic curriculum components. Of 66 programs, 42 (64%) responded to the survey. Of the responding programs, 35 (83%) were university-based or university-affiliated, while 7 (17%) were independent. Most programs were in the Midwest (33%). Forty-one (98%) reported having a surgicalssessments, and definitions of minimum case requirements to ensure adequate training.This study demonstrated that almost all CRS residencies have integrated RS and have trainees operating at the robotic console. Most programs have a robotics curriculum and there are expanding indications for RS within CRS. This expansion calls for discussion on implementation of training standards such as curricular requisites, baseline competency assessments, and definitions of minimum case requirements to ensure adequate training. Anastomotic leakage (AL) and major complications after colorectal resection for deep infiltrating endometriosis (DIE) have a remarkable impact on patient outcomes. The aim of this study is to assess the predictive value of C-reactive protein (CRP), procalcitonin (PCT), white blood cell count (WBCs) and the Dutch Leakage Score (DLS) as reliable markers in the early diagnosis of AL and major complications after laparoscopic colorectal resection for DIE. 262 consecutive women undergoing laparoscopic colorectal resection for DIE between September 2017 and September 2018 were prospectively enrolled. WBCs, CRP, PCT and DLS were recorded at baseline and on postoperative day (POD) 2, 3 and 6 then statistically analyzed as predictors of AL and severe postoperative complications. The AL rate was 3.2%. The major morbidity rate was 11.2%. No postoperative mortality was recorded. The postoperative trend of DLS and serum levels of CRP and PCT, but not WBCs, were significantly higher in women developing AL and severe complications. https://www.selleckchem.com/products/pi3k-hdac-inhibitor-i.html DLS had better sensitivity and specificity than biomarkers on all postoperative days as a predictor of AL and major complications. CRP and PCT have a low positive predictive value (PPV) and a high negative predictive value (NPV) for AL and major complications on POD3 and POD6. The risk of malnutrition was significantly related to AL. The combination of DLS as a standardized postoperative clinical monitoring system and CRP and PCT as serum biomarkers, allows the exclusion of AL and major complications in the early postoperative period after laparoscopic colorectal resection for DIE, thus ensuring a safe patient discharge.The combination of DLS as a standardized postoperative clinical monitoring system and CRP and PCT as serum biomarkers, allows the exclusion of AL and major complications in the early postoperative period after laparoscopic colorectal resection for DIE, thus ensuring a safe patient discharge. Third-space endoscopy requires a delicate and accurate insufflation technique to secure the endoscopic visualization and maintain the working space. However, optimal third-space insufflation parameters have yet to be determined. The aim of this study was to assess (1) the diversity of endoluminal third-space pressure by manual insufflation, and (2) the performance of the insufflation settings for third-space endoscopy. A submucosal tunnel was created in the upper posterior wall of the porcine stomach. Using two-channel esophagogastroduodenoscopy, one channel was used for insufflation and the other was used for pressure measurement. Experiment 1 Endoluminal submucosal tunnel pressure was measured in a 10-cm submucosal tunnel of a single porcine. Six board-certified endoscopists in turn maintained what they considered sufficient exposure under manual insufflation. Experiment 2 Endoluminal submucosal tunnel pressure and number of insufflations were measured using the pressure-regulated insufflation device; the differences in the submucosal tunnel length (long 10-cm, short 4-cm) and the insufflation route diameter (large 3.8-mm, small 2.2-mm) were compared. Experiment 1 The endoluminal submucosal tunnel pressure profiles during third-space endoscopy varied between endoscopists. Experiment 2 Longer submucosal tunnels and larger insufflation route diameters lead to stable endoluminal submucosal tunnel pressure. The gap with the preset pressure of the insufflator and endoluminal pressure narrowed, and the required number of insufflations decreased with longer tunnel length and larger route diameter. The pressure dynamics in third-space endoscopy differed among endoscopists. Longer submucosal tunnels and larger insufflation route diameters lead to stable endoluminal submucosal tunnel pressure.The pressure dynamics in third-space endoscopy differed among endoscopists.

Routine use of intraoperative cholangiography (IOC) during laparoscopic cholecystectomy (LC) for detecting common bile duct stones remains controversial. The 2016 World Society of Emergency Surgery (WSES) guidelines on acute calculous cholecystitis proposed a risk stratification for choledocholithiasis. Our present study aimed to (1) examine the findings of common bile duct (CBD) stones in patients underwent LC with routine use of IOC, and (2) validate the 2016 WSES risk classes for predicting choledocholithiasis. All patients had LC with IOC routinely performed from November 2012 to December 2017 were reviewed retrospectively. Patients were classified into high-, intermediate-, and low-risk groups based on the 2016 WSES risk classes with modification. A total of 990 patients with LC and routine IOC were enrolled. CBD stones were detected in 197 (19.9%) patients. The rate of CBD stone detected in low-, intermediate-, high-risk groups were 0%, 14.2%, and 89.6%, respectively. Predictors as following evidence of CBD stones on abdominal ultrasound or computed tomography, CBD diameter > 6mm, total bilirubin > 4mg/dL, bilirubin level = 1.
