Leaning in and moving forward: a call to action and review of diversity initiatives in SAGES.

BACKGROUND: Diversity, equity, and inclusion have been an intentional focus for SAGES well before the COVID-19 pandemic and the coincident societal recognition of social injustices and racism. Longstanding inequities within our society, healthcare, and the surgery profession have come to light in the aftermath of events that rose to attention around the time of Covid. In so doing, they have brought into focus disparities, injustices, and inequalities that have long been present in the field of surgery, selectively affecting the most vulnerable. METHODS: This White paper examines the current state of diversity within the field of surgery and SAGES (Society of American Gastrointestinal and Endoscopic Surgeons) approach and effort to pave the way forward to meaningful change. We delineate the imperative for diversity, equity, and inclusion for all. By all, we mean to be inclusive of the diversity of gender and sexual orientation, race, ethnicity, geography, sex, and disability in the field of surgery. RESULTS: SAGES is an organization that lives at the intersection of education and innovation. It has a vital role in assisting the surgical profession in addressing these issues and needs and being a force alongside others for sustained and necessary change. SAGES can only realize these goals through a commitment across all aspects of the organization to embed diversity, equity, and inclusion into our very fabric. CONCLUSION: True diversity, equity, and inclusion within a surgical organization is vital for its longevity, growth, relevance, and impact. Unfortunately, the absence of DEI limits opportunity, robs the organization of collective intelligence in an environment in which its presence is critical, contributes to health inequities, and impoverishes all within the society and its value to all with whom it interfaces. SAGES is an organization that lives at the intersection of education and innovation. It has a vital role in assisting the surgical profession in addressing these issues and needs and being a force alongside others for sustained and necessary change. SAGES can only realize these goals through a commitment across all aspects of the organization to embed diversity, equity, and inclusion into our very fabric. Strategies like those highlighted in this White Paper, may be within our grasp and we can learn yet more if we remain in a place of humility and teachability in the future.

The impact of bowel dysfunction on health-related quality of life after rectal cancer surgery: a systematic review.

BACKGROUND: Symptoms of bowel dysfunction after sphincter-preserving rectal cancer surgery have an important impact on health-related quality of life (HRQOL), but that relationship is complex. A better understanding of this relationship allows for better informed shared decision-making about surgery. Our objective was to perform a systematic review to determine which HRQOL domains are most affected by postoperative bowel dysfunction. METHODS: A systematic review of the CINAHL, Cochrane Library, Embase, Medline, PsycInfo, PubMed, Web of Science, and Scopus databases was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We included studies that evaluated bowel function after sphincter-preserving rectal cancer surgery and assessed HRQOL using a validated instrument. The quality of HRQOL analysis was assessed using an 11-item checklist. The main outcome was the impact bowel dysfunction had on global and domain specific quality-of-life indices. The impact was evaluated for clinical relevance using the Minimum Clinical Important Difference (MCID) for each specific HRQOL instrument. RESULTS: Out of 952 unique citations, 103 studies were full-text reviews. Eighteen studies met the inclusion criteria (4 prospective cohorts and 9 cross-sectional studies). Of the 15 studies with long-term follow-up, the time to assessment after surgery ranged from 1.2 to 14.6 years. The low anterior resection syndrome score and European Organization for Research and Treatment core quality-of-life questionnaire (EORTC QLQ-C30) were the most commonly used instruments. Medium and large magnitudes in MCID were seen for global health, social functioning, emotional functioning, fatigue, diarrhea, and financial difficulties. Among included studies, the most consistently reported functional domains affected by bowel function were social functioning and emotional functioning. CONCLUSIONS: Following sphincter-preserving rectal cancer surgery, poor bowel function mainly affects the social and emotional functional domains of HRQOL, which in turn impact global scores. This finding can help inform patients about expected changes in HRQOL after rectal cancer surgery and facilitate individualized treatment decisions.

Trajectory of change of low anterior resection syndrome over time after restorative proctectomy for rectal adenocarcinoma.

BACKGROUND: Restorative proctectomy for rectal cancer is associated with a high incidence of low anterior resection syndrome (LARS), but few studies report longitudinal results for bowel function. The aim of our study was to examine the trajectory of change of LARS over the first 18 months after restorative proctectomy for rectal cancer. METHODS: A prospective database measuring functional outcomes in rectal cancer patients from a single university-affiliated specialist colorectal referral center from 10/2018 to 03/2020 was queried. Patients were included in this study if they underwent restorative proctectomy for rectal cancer and had at least three assessments in the first 18 months after primary surgery or after closure of proximal diversion. Bowel function was assessed using the LARS score, administered at every surveillance follow-up after restoration of bowel continuity. Latent-class growth curve (trajectory) analysis was used to identify different trajectories of LARS changes over the first 18 months and group patients into these trajectory groups. These groups were then compared to identify predictors for each trajectory. RESULTS: A total of 95 patients were included (63 males, mean age. 61.3 ± 12.5 years). Trajectory analysis identified three distinct trajectory groups. Group 1 had stable minimal LARS over time (26%). Group 2 had early LARS scores consistent with the minor LARS category and improved with time (28%). Group 3 had persistently high LARS scores (45%). Neoadjuvant therapy, intersphincteric resection, and proximal diversion were more common in group 3. CONCLUSIONS: We identified three main trajectories of change of LARS in the 18 months after restorative proctectomy. These data may be used to better inform patients of their expected postoperative bowel function.

Gender distribution of speakers on panels at the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) annual meeting.

BACKGROUND: Speaking invitations are used by faculty promotion committees as evidence of external recognition. However, women are underrepresented as speakers at specialty society conferences despite the rise in women physicians. The purpose of this study was to estimate to what extent the gender of session conveners is associated with the gender distribution of invited speakers at SAGES meetings. METHODS: A retrospective audit of annual SAGES meeting programs during 2009-2018 was performed. All invited panel speakers, defined as faculty delivering a prepared oral presentation in a session under the organization of one or more chairs, were identified. The gender of speakers and chairs/co-chairs was determined. Hands-on courses, paper sessions, military symposia, mock trials, and jeopardy sessions were excluded. We compared the proportion of all-male panels in sessions with all-male conveners versus sessions with at least one woman convener. Statistical analysis was performed using Chi-square and t tests. RESULTS: There were 3405 speakers and 459 panels identified. After applying inclusion and exclusion criteria, 2836 invited speakers on 402 panels were analyzed. Women represented 15% of all speakers, increasing from 9 to 19% (2009 to 2018). This reflects the rise in the proportion of women overall members (11% in 2010 to 19% in 2018). The proportion of panels with at least one woman convener increased from 12 to 58%. All-male panels represented 40% of all panels (n = 163) and their proportion significantly decreased over time from 50 to 31% (p trend < 0.000). Sessions with all-male conveners had 52% all-male panels, while sessions with at least one woman convener had 19% all-male panels (p < 0.001). CONCLUSION: The proportion of women invited speakers at the annual SAGES meeting has significantly increased over time. All-male convener sessions were more likely to convene all-male speaker panels. Including a woman chair/co-chair increased the number of women speakers and is a successful strategy to achieve gender balance in conference planning.

The impact of complications after elective colorectal resection within an enhanced recovery pathway.

BACKGROUND: Despite the implementation of enhanced recovery pathways (ERP), morbidity following colorectal surgery remains high. The aim of the present study was to estimate the impact of postoperative complications on excess hospital length of stay (LOS) in patients undergoing elective colorectal resection. METHODS: A retrospective study of patients undergoing elective colorectal surgery at a single institution from 2003 to 2010 was performed. Patients managed by an ERP were compared to conventional care (CC), matched by propensity score radius matching. Complications were defined a priori. Excess (independent effect on LOS from multivariate analysis) and attributable (absolute number of additional bed days) LOS of common postoperative complications determined the impact of complications on bed utilization. Multivariate analysis was performed using multiple linear regression. RESULTS: A total of 810 propensity-score-matched patients were included (ERP = 472, CC = 338). Complications were significantly lower in the ERP group compared to the CC group (20 vs. 31%, p < 0.001). Median LOS decreased from 7 days in the CC group to 5 days in the ERP group [adjusted decrease in mean LOS of 2.8 days (95% CI 0.8, 4.8)]. Anastomotic leak, myocardial infarction and C. difficile infection had the highest excess LOS for both the ERP and CC groups. However, impaired gastrointestinal function had a higher impact on the absolute number of hospital bed days in the ERP group, as high as anastomotic leak (72.7 vs. 73.5 days respectively), while in the CC group the impact of gastrointestinal dysfunction was less of that of anastomotic leak (50.6 vs. 78.9 days respectively). CONCLUSIONS: In the setting of an ERP, postoperative complications have significant impact on total bed utilization. Impaired gastrointestinal function, given its high incidence, accounted for almost the same number of additional hospital bed days as anastomotic leak in the ERP group and is a target for quality improvement.

The effects of added whey protein to a pre-operative carbohydrate drink on glucose and insulin response.

BACKGROUND: Pre-operative complex carbohydrate (CHO) drinks are recommended to attenuate post-operative insulin resistance. However, many institutions use simple CHO drinks, which while convenient, may have less metabolic effects. Whey protein may enhance insulin release when added to complex CHO. The aim of this study was to compare the insulin response to simple CHO vs. simple CHO supplemented with whey protein. METHODS: Twelve healthy volunteers participated in this double-blinded, within subject, cross-over design study investigating insulin response to simple CHO drink vs. simple CHO + whey (CHO + W) drink. The primary outcome was the accumulated insulin response during 180 min after ingestion of the drinks (Area under the curve, AUC). Secondary outcomes included plasma glucose and ghrelin levels, and gastric emptying rate estimated by acetaminophen absorption technique. Data presented as mean (SD). RESULTS: There was no differences in accumulated insulin response after the CHO or CHO + W drinks [AUC: 15 (8) vs. 20 (14) nmol/l, P = 0.27]. Insulin and glucose levels peaked between 30 and 60 min and reached 215 (95) pmol/l and 7 (1) mmol/l after the CHO drink and to 264 (232) pmol/l and 6.5 (1) mmol/l after the CHO + W drink. There were no differences in glucose or ghrelin levels or gastric emptying with the addition of whey. CONCLUSION: The addition of whey protein to a simple CHO drink did not change the insulin response in healthy individuals. The peak insulin responses to simple CHO with or without whey protein were lower than that previously reported with complex CHO drinks. The impact of simple carbohydrate drinks with lower insulin response on peri-operative insulin sensitivity requires further study.

Enhanced Recovery After Surgery (ERAS) for gastrointestinal surgery, part 2: consensus statement for anaesthesia practice.

BACKGROUND: The present interdisciplinary consensus review proposes clinical considerations and recommendations for anaesthetic practice in patients undergoing gastrointestinal surgery with an Enhanced Recovery after Surgery (ERAS) programme. METHODS: Studies were selected with particular attention being paid to meta-analyses, randomized controlled trials and large prospective cohort studies. For each item of the perioperative treatment pathway, available English-language literature was examined and reviewed. The group reached a consensus recommendation after critical appraisal of the literature. RESULTS: This consensus statement demonstrates that anaesthesiologists control several preoperative, intraoperative and postoperative ERAS elements. Further research is needed to verify the strength of these recommendations. CONCLUSIONS: Based on the evidence available for each element of perioperative care pathways, the Enhanced Recovery After Surgery (ERAS®) Society presents a comprehensive consensus review, clinical considerations and recommendations for anaesthesia care in patients undergoing gastrointestinal surgery within an ERAS programme. This unified protocol facilitates involvement of anaesthesiologists in the implementation of the ERAS programmes and allows for comparison between centres and it eventually might facilitate the design of multi-institutional prospective and adequately powered randomized trials.

The outcomes of the elderly in acute care general surgery.

INTRODUCTION: Elderly patients form a growing subset of the acute care surgery (ACS) population. Older age may be associated with poorer outcomes for some elective procedures, but there are few studies focusing on outcomes for the elderly ACS population. Our objective is to characterize differences in mortality and morbidity for acute care surgery patients >80 years old. METHODS: A retrospective review of all ACS admissions at a large teaching hospital over 1 year was conducted. Patients were classified into non-elderly (<80 years old) and elderly (≥80 years old). In addition to demographic differences, outcomes including care efficiency, mortality, postoperative complications, and length of stay were studied. Data analysis was completed with the Student's t test for continuous variables and Fisher's exact test for categorical variables using STATA 12 (College Station, TX, USA). RESULTS: We identified 467 non-elderly and 60 elderly patients with a mean age-adjusted Charlson score of 3.2 and 7.2, respectively (p < 0.001) and a mortality risk of 1.9 and 11.7 %, respectively (p < 0.001). The elderly were at risk of longer duration (>4 days) hospital stay (p = 0.05), increased postoperative complications (p = 0.002), admission to the ICU (p = 0.002), and were more likely to receive a non-operative procedure (p = 0.003). No difference was found (p = NS) for patient flow factors such as time to consult general surgery, time to see consult by general surgery, and time to operative management and disposition. CONCLUSIONS: Compared to younger patients admitted to an acute care surgery service, patients over 80 years old have a higher risk of complications, are more likely to require ICU admission, and stay longer in the hospital.

Enhanced Recovery After Surgery (ERAS) for gastrointestinal surgery, part 1: pathophysiological considerations.

BACKGROUND: The present article has been written to convey concepts of anaesthetic care within the context of an Enhanced Recovery After Surgery (ERAS) programme, thus aligning the practice of anaesthesia with the care delivered by the surgical team before, during and after surgery. METHODS: The physiological principles supporting the implementation of the ERAS programmes in patients undergoing major abdominal procedures are reviewed using an updated literature search and discussed by a multidisciplinary group composed of anaesthesiologists and surgeons with the aim to improve perioperative care. RESULTS: The pathophysiology of some key perioperative elements disturbing the homoeostatic mechanisms such as insulin resistance, ileus and pain is here discussed. CONCLUSIONS: Evidence-based strategies aimed at controlling the disruption of homoeostasis need to be evaluated in the context of ERAS programmes. Anaesthesiologists could, therefore, play a crucial role in facilitating the recovery process.

Current practices of laparoscopic inguinal hernia repair: a population-based analysis.

PURPOSE: The selection of a laparoscopic approach for inguinal hernias varies among surgeons. It is unclear what is being done in actual practice. The purpose of this study was to report practice patterns for treatment of inguinal hernias among Quebec surgeons, and to identify factors that may be associated with the choice of operative approach. METHODS: We studied a population-based cohort of patients who underwent an inguinal hernia repair between 2007 and 2011 in Quebec, Canada. A generalized linear model was used to identify predictors associated with the selection of a laparoscopic approach. RESULTS: 49,657 inguinal hernias were repaired by 478 surgeons. Laparoscopic inguinal hernia repair (LIHR) was used in 8 % of all cases. LIHR was used to repair 28 % of bilateral hernias, 10 % of recurrent hernias, 6 % of unilateral hernias, and 4 % of incarcerated hernias. 268 (56 %) surgeons did not perform any laparoscopic repairs, and 11 (2 %) surgeons performed more than 100 repairs. These 11 surgeons performed 61 % of all laparoscopic cases. Patient factors significantly associated with having LIHR included younger age, fewer comorbidities, bilateral hernias, and recurrent hernias. CONCLUSION: An open approach is favored for all clinical scenarios, even for situations where published guidelines recommend a laparoscopic approach. Surgeons remain divided on the best technique for inguinal hernia repair: while more than half never perform LIHR, the small proportion who perform many use the technique for a large proportion of their cases. There appears to be a gap between the best practices put forth in guidelines and what surgeons are doing in actual practice. Identification of barriers to the broader uptake of LIHR may help inform the design of educational programs to train those who have the desire to offer this technique for certain cases, and have the volume to overcome the learning curve.

Meta-analysis of the effect of goal-directed therapy on bowel function after abdominal surgery.

BACKGROUND: Intraoperative goal-directed therapy (GDT) was introduced to titrate intravenous fluids, with or without inotropic drugs, based on objective measures of hypovolaemia and cardiac output measurements to improve organ perfusion. This meta-analysis aimed to determine the effect of GDT on the recovery of bowel function after abdominal surgery. METHODS: MEDLINE, Embase, the Cochrane Library and PubMed databases were searched for randomized clinical trials and cohort studies, from January 1989 to June 2013, that compared patients who did, or did not, receive intraoperative GDT, and reported outcomes on the recovery of bowel function. Time to first flatus and first bowel motion, time to tolerate oral diet, postoperative nausea and vomiting, and primary postoperative ileus were included. RESULTS: Thirteen trials with 1399 patients were included in the analysis. GDT shortened the time to the first bowel motion (weighted mean difference (WMD -0·67, 95 per cent c.i. -1·23 to -0·11; P = 0·020) and time to tolerate oral intake (WMD -0·95, -1·81 to -0·10; P = 0·030), and reduced postoperative nausea and vomiting (risk difference -0·15, -0·26 to -0·03; P = 0·010). When only high-quality studies were included, GDT reduced only the time to tolerate oral intake (WMD -1·18, -2·03 to -0·33; P = 0·006). GDT was more effective outside enhanced recovery programmes and in patients undergoing colorectal surgery. CONCLUSION: GDT facilitated the recovery of bowel function, particularly in patients not treated within enhanced recovery programmes and in those undergoing colorectal operations.

A survey of general surgeons regarding laparoscopic inguinal hernia repair: practice patterns, barriers, and educational needs.

PURPOSE: Practice patterns for inguinal hernia repair vary significantly among surgeons. The purpose of this study was to identify perceived indications for laparoscopic inguinal hernia repair (LIHR), and to identify barriers to its adoption and educational needs for surgeons. METHODS: A web-based survey was sent to general surgery members of several North American surgical societies, and to surgical residents through program directors. The 33-item survey was divided in 4 sections: demographics, utilization of techniques, management based on 11 clinical scenarios, reasons for not performing LIHR and educational needs for those who want to learn. RESULTS: Six hundred and ninety-seven general surgeons and 206 general surgery residents responded to the survey. Surgeons with MIS fellowships, and surgeons at the beginning of their careers are more likely to perform LIHR. Out of the 11 clinical scenarios, surgeons preferred a laparoscopic approach (totally extraperitoneal or transabdominal preperitoneal) for bilateral (48 %) and recurrent (44 %) hernias. However, 46 % of respondents never perform LIHR. Of these, 70 % consider the benefits of laparoscopy to be minimal, 59 % said they lack the requisite training, and 26 % are interested in learning. Surgeons (70 %) and residents (73 %) agreed that the best educational method would be a course followed by expert proctoring. CONCLUSION: Surgeons remain divided on the utility of laparoscopic surgery for inguinal hernia repair. Nearly half of responding surgeons never perform LIHR, and the other half offer it selectively. One quarter of surgeons who do not perform LIHR are interested in learning. This reveals a knowledge gap that could be addressed with educational programs.

Colonoscopy performance correlates with scores on the FES™ manual skills test.

INTRODUCTION: Achieving proficiency in flexible endoscopy is a major priority for general surgery training programs. The Fundamentals of Endoscopic Surgery (FES™) is a high-stakes examination of the knowledge and skills required to perform flexible endoscopy. The objective of this study was to establish additional evidence for the validity of the FES™ hands-on test as a measure of flexible endoscopy skills by correlating clinical colonoscopy performance with FES™ score. METHODS: Participants included FES™-naïve general surgery residents, gastroenterology fellows at all levels of training and attending physicians who regularly perform colonoscopy. Each participant completed a live colonoscopy and the FES™ hands-on test within 2 weeks. Performance on live colonoscopy was measured using the Global Assessment of Gastrointestinal Endoscopic Skills-Colonoscopy (GAGES-C, maximum score 20), and performance on the FES™ hands-on test was assessed by the simulator's computerized scoring system. The clinical assessor was blinded to simulator performance. Scores were compared using Pearson's correlation coefficient. RESULTS: A total of 24 participants were enrolled (mean age 30; 54 % male) with a broad range of endoscopy experience; 17 % reported no experience, 54 % had <25 previous colonoscopies; and 21 % had >100. The FES™ and GAGES scores reflected the broad range of endoscopy experience of the study group (FES™ score range 32-105; GAGES score range 5-20). Pearson's correlation coefficient between GAGES-C scores and FES™ hands-on test scores was 0.78 (0.54-0.90, p < 0.0001). All eight participants with GAGES-C score >15/20 achieved a passing score on the FES™ hands-on test. CONCLUSION: There is a strong correlation between clinical colonoscopy performance and scores achieved on the FES™ hands-on test. These data support the validity of FES™ as a measure of colonoscopy skills.

Outcomes reported in high-impact surgical journals.

BACKGROUND: With advances in operative technique and perioperative care, traditional endpoints such as morbidity and mortality provide an incomplete description of surgical outcomes. There is increasing emphasis on the need for patient-reported outcomes (PROs) to evaluate fully the effectiveness and quality of surgical interventions. The objective of this study was to identify the outcomes reported in clinical studies published in high-impact surgical journals and the frequency with which PROs are used. METHODS: Electronic versions of material published between 2008 and 2012 in the four highest-impact non-subspecialty surgical journals (Annals of Surgery, British Journal of Surgery (BJS), Journal of the American College of Surgeons (JACS), Journal of the American Medical Association (JAMA) Surgery) were hand-searched. Clinical studies of adult patients undergoing planned abdominal, thoracic or vascular surgery were included. Reported outcomes were classified into five categories using Wilson and Cleary's conceptual model. RESULTS: A total of 893 articles were assessed, of which 770 were included in the analysis. Some 91·6 per cent of studies reported biological and physiological outcomes, 36·0 per cent symptoms, 13·4 per cent direct indicators of functional status, 10·6 per cent general health perception and 14·8 per cent overall quality of life (QoL). The proportion of studies with at least one PRO was 38·7 per cent overall and 73·4 per cent in BJS (P < 0·001). The proportion of studies using a formal measure of health-related QoL ranged from 8·9 per cent (JAMA Surgery) to 33·8 per cent (BJS). CONCLUSION: The predominant reporting of clinical endpoints and the inconsistent use of PROs underscore the need for further research and education to enhance the applicability of these measures in specific surgical settings.

Systematic review of outcomes used to evaluate enhanced recovery after surgery.

BACKGROUND: Enhanced recovery pathways (ERPs) aim to improve patient recovery. However, validated outcome measures to evaluate this complex process are lacking. The objective of this review was to identify how recovery is measured in ERP studies and to provide recommendations for the design of future studies. METHODS: A systematic search of MEDLINE, Embase and Cochrane databases was conducted. Prospective studies evaluating ERPs compared with traditional care in abdominal surgery published between 2000 and 2013 were included. All reported outcomes were classified into categories: biological and physiological variables, symptom status, functional status, general health perceptions and quality of life (QoL). The phase of recovery measured was defined as baseline, intermediate (in hospital) and late (following discharge). RESULTS: A total of 38 studies were included based on the systematic review criteria. Biological or physiological variables other than postoperative complications were reported in 30 studies, and included return of gastrointestinal function (25 studies), pulmonary function (5) and physical strength (3). Patient-reported symptoms, including pain (16 studies) and fatigue (9), were reported less commonly. Reporting of functional status outcomes, including mobilization (16 studies) and ability to perform activities of daily living (4), was similarly uncommon. Health aspects of QoL were reported in only seven studies. Length of follow-up was generally short, with 24 studies reporting outcomes within 30 days or less. All studies documented in-hospital outcomes (intermediate phase), but only 17 reported postdischarge outcomes (late phase) other than complications or readmission. CONCLUSION: Patient-reported outcomes, particularly postdischarge functional status, were not commonly reported. Future studies of the effectiveness of ERPs should include validated, patient-reported outcomes to estimate better their impact on recovery, particularly after discharge from hospital.

Impact of a bladder scan protocol on discharge efficiency within a care pathway for ambulatory inguinal herniorraphy.

BACKGROUND: Postoperative urinary retention (POUR) is a common complication of ambulatory inguinal herniorraphy, with an incidence reaching 38%, and many surgeons require patients to void before discharge. This study aimed to assess whether the implementation of a bladder scan-based voiding protocol reduces the time until discharge after ambulatory inguinal herniorraphy without increasing the rate of POUR. METHODS: As part of a perioperative care pathway, a protocol was implemented to standardize decision making after elective inguinal hernia repair (February 2012). Patients were assessed with a bladder scan, and those with <600 mL of urine were discharged home, whereas those with more than 600 mL of urine had an in-and-out catheterization before discharge. The patients received written information about urinary symptoms and instructions to present to the emergency department if they were unable to void at home. An audit of scheduled outpatient inguinal hernia repairs between October 2011 and July 2012 was performed. Comparisons were made using the t test, Fisher's exact test, and Wilcoxon rank sum test where appropriate. Statistical significance was defined a priori as a p value lower than 0.05. RESULTS: During the study period, 124 patients underwent hernia repair: 60 before and 64 after implementation of the protocol. The findings showed no significant differences in patient characteristics, laparoscopic approach (35 vs. 33%; p = 0.80), proportion receiving general anesthesia (70 vs. 73%; p = 0.67), or amount of intravenous fluids given (793 vs. 663 mL; p = 0.07). The proportion of patients voiding before discharge was higher after protocol implementation (73 vs. 89%; p = 0.02). The protocol had no impact on median time to discharge (190 vs. 205 min; p = 0.60). Only one patient in each group presented to the emergency department with POUR (2%). CONCLUSION: After ambulatory inguinal herniorraphy, implementation of a bladder scan-based voiding protocol did not result in earlier discharge. The incidence of POUR was lower than reported in the literature.

Economic impact of an enhanced recovery pathway for oesophagectomy.

BACKGROUND: Data are lacking to support the cost-effectiveness of enhanced recovery pathways (ERP) for oesophagectomy. The aim of this study was to investigate the impact of an ERP on medical costs for oesophagectomy. METHODS: This study investigated all patients undergoing elective oesophagectomy between June 2009 and December 2011 at a single high-volume university hospital. From June 2010, all patients were enrolled in an ERP. Clinical outcomes were recorded for up to 30 days. Deviation-based cost modelling was used to compare costs between the traditional care and ERP groups. RESULTS: A total of 106 patients were included (47 traditional care, 59 ERP). There were no differences in patient, pathological and operative characteristics between the groups. Median length of hospital stay (LOS) was lower in the ERP group (8 (interquartile range 7-18) days versus 10 (9-18) days with traditional care; P = 0·019). There was no difference in 30-day complication rates (59 per cent with ERP versus 62 per cent with traditional care; P = 0·803), and the 30-day or in-hospital mortality rate was low (3·8 per cent, 4 of 106). Costs in the on-course and minor-deviation groups were significantly lower after implementation of the ERP. The pathway-dependent cost saving per patient was €1055 and the overall cost saving per patient was €2013. One-way sensitivity analysis demonstrated that the ERP was cost-neutral or more costly only at extreme values of ward, operating and intensive care costs. CONCLUSION: A multidisciplinary ERP for oesophagectomy was associated with cost savings, with no increase in morbidity or mortality.

The association of the distance walked in 6 min with pre-operative peak oxygen consumption and complications 1 month after colorectal resection.

We measured the distance 112 patients walked in 6 min, as well as their peak oxygen consumption pedalling a bicycle, week before scheduled resection of benign or malignant colorectal disease. The distance walked correlated with peak oxygen consumption, the former 'accounting' for about half the variation in the latter, r² 0.52 (95% CI 0.38-0.64), p < 0.0001. In the first postoperative month, 42/112 patients experienced a complication. In multivariate analysis, complications were less likely with longer walking distances and increasing age: the odds ratio (95% CI) reduced to 0.995 (0.990-0.999) for each metre distance, and to 0.96 (0.93-0.99) with each year of age, p = 0.025 and p = 0.018, respectively. The distance walked in 6 min before surgery can provide prognostic information when cardiopulmonary exercise testing is unavailable.
