Society of American Gastrointestinal and Endoscopic Surgeons guidelines development: health equity update to standard operating procedure.

INTRODUCTION: The SAGES Guidelines Committee creates evidence-based clinical practice guidelines. Due to existing health disparities, recommendations made in these guidelines may have different impacts on different populations. The updates to our standard operating procedure described herein will allow us to produce well-designed guidelines that take these disparities into account and potentially reduce health inequities. METHODS: This paper outlines updates to the SAGES Guidelines Committee Standard Operating Procedure in order to incorporate issues of heath equity into our guideline development process with the goal of minimizing downstream health disparities. RESULTS: SAGES has developed an evidence-based, standardized approach to consider issues of health equity throughout the guideline development process to allow physicians to better counsel patients and make research recommendations to better address disparities. CONCLUSION: Societies that promote guidelines within their organization must make an intentional effort to prevent the widening of health disparities as a result of their recommendations. The updates to the Guidelines Committee Standard Operating Procedure will hopefully lead to increased attention to these disparities and provide specific recommendations to reduce them.

Intraluminal Anastomotic Assessment Using Indocyanine Green Near-Infrared Imaging for Left-Sided Colonic and Rectal Resections: a Systematic Review.

BACKGROUND: Indocyanine green fluorescence angiography (ICG-FA) has been used in colorectal surgery to assess anastomotic perfusion and reduce the risks of anastomotic leaks. The main objective of this paper is to review the data on the transanal application of ICG-FA for the intraluminal assessment of colorectal anastomosis. METHODS: A literature search was conducted for articles published between 2011 and 2021 using PubMed and Cochrane databases, related to the application of ICG for the intraluminal assessment of colorectal anastomosis. Original scientific manuscripts, review articles, meta-analyses, and case reports were considered eligible. RESULTS: A total of 305 studies have been identified. After abstract screening for duplicates, 285 articles remained. Of those, 271 were not related to the topic of interest, 4 were written in a language other than English, and 4 had incomplete data. Six articles remained for the final analysis. The intraluminal assessment of colorectal anastomosis with ICG-FA is feasible, safe, and may reduce the incidence of leaks. CONCLUSION: The intraluminal assessment of anastomotic perfusion via ICG-FA may be a promising novel application of ICG technology. More data is needed to support this application further to reduce leak rates after colorectal surgery, and future randomized clinical trials are awaited.

Concordance of financial disclosures among faculty at the 2018-2020 SAGES annual meetings.

BACKGROUND: Financial relationships with industry may bias educational content delivered by physicians. SAGES strives to mitigate potential bias, relying on physician self-reporting. Retrospective review of relationships is possible using the Open Payments Database (OPD), a public record of industry-reported payments to US physicians. We aimed to evaluate the effectiveness of the SAGES disclosure process by comparing faculty disclosures to SAGES, faculty disclosures within presentations, and OPD records among speakers at the 2018-2020 SAGES meetings. METHODS: We reviewed all presentations from the SAGES 2018-2020 Annual Meetings. For each invited presentation, all slide-disclosed relationships were recorded. For US physicians, we queried the OPD and recorded relationships ≥ $500 USD in the calendar year prior to presentation. We compared the slide-disclosed relationships with OPD-reported relationships and with those provided to SAGES during the faculty disclosure process. We surveyed a sample of the 2020 annual meeting speakers to analyze potential reasons for discordance. RESULTS: From 2018 to 2020, there were 1,355 invited presentations, of which 1,234 (91%) were available for review. Disclosure slides were present in 1,098 (89%), increasing from 86% in 2018 to 93% in 2020. The proportion of speakers with OPD-reported relationships ≥ $500 increased from 54% in 2018 to 66% in 2020. The total value of OPD relationships decreased from $5.9 million (2018) to $3.3 million (2020) with a concomitant decrease in the proportion with high discordance from 9% in 2018 to 5% in 2020. Among the 2020 speakers with high discordance, the most common explanations for discordance were being unaware of payment or payment outside the 12-month timeframe (55%). CONCLUSIONS: Discordance between financial disclosures reported to SAGES and OPD highlight the need for improvements in the faculty disclosure process. SAGES will continue to streamline this process by incorporating faculty review of their OPD disclosures to ensure all educational programs remain free of commercial bias.

Assessment of a circular powered stapler for creation of anastomosis in left-sided colorectal surgery: A prospective cohort study.

BACKGROUND: Circular staplers perform a critical function for creation of anastomoses in colorectal surgeries. Powered stapling systems allow for reduced force required by surgeons to fire the device and may provide advantages for creating a secure anastomosis. The objective of this study was to evaluate the clinical performance of a novel circular powered stapler in a post-market setting, during left-sided colectomy procedures. MATERIALS AND METHODS: Consecutive subjects underwent left-sided colorectal resections that included anastomosis performed with the ECHELON CIRCULAR™ Powered Stapler (ECP). The primary endpoint was the frequency in which a stapler performance issue was observed. Secondary endpoints included evaluation of ease of use of the device via a surgeon satisfaction questionnaire, and monitoring/recording of procedure-related adverse events (AEs). RESULTS: A total of 168 anastomoses were performed with the ECP. Surgical approaches included robotic-assisted (n = 74, 44.0%), laparoscopic (n = 71, 42.3%), open (n = 20, 11.9%), and hand-assisted minimally invasive (n = 3, 1.8%) procedures. There were 22 occurrences of device performance issues in 20 (11.9%) subjects during surgery. No positive intraoperative leak tests were observed, and only 1 issue was related to a procedure-related AE or surgical complication, which was an instance of incomplete surgical donut necessitating re-anastomosis. Postoperative anastomotic leaks were experienced in 4 (2.4%) subjects. Clavien-Dindo classification of all AEs indicated that 92.0% were Grades I or II. Participating surgeons rated the ECP as easier to use compared to previously used manual circular staplers in 85.7% of procedures. CONCLUSION: The circular powered stapler exhibited few clinically relevant performance issues, an overall favorable safety profile, and ease of use for creation of left-sided colon anastomoses.

SAGES primer for taking care of yourself during and after the COVID-19 crisis.

COVID-19 is a pandemic which has affected almost every aspect of our life since starting globally in November 2019. Given the rapidity of spread and inadequate time to prepare for record numbers of sick patients, our surgical community faces an unforeseen challenge. SAGES is committed to the protection and care of patients, their surgeons and staff, and all who are served by the medical community at large. This includes physical health, mental health, and well-being of all involved. The fear of the unknown ahead can be paralyzing. International news media have chronicled the unthinkable situations that physicians and other health care providers have been thrust into as a result of the COVID-19 pandemic. These situations include making life or death decisions for patients and their families regarding use of limited health care resources. It includes caring for patients with quickly deteriorating conditions and limited treatments available. Until recently, these situations seemed far from home, and now they are in our own hospitals. As the pandemic broadened its reach, the reality that we as surgeons may be joining the front line is real. It may be happening to you now; it may be on the horizon in the coming weeks. In this context, SAGES put together this document addressing concerns on clinician stressors in these times of uncertainty. We chose to focus on the emotional toll of the situation on the clinician, protecting vulnerable persons, reckoning with social isolation, and promoting wellness during this crisis. At the same time, the last part of this document deals with the "light at the end of the tunnel," discussing potential opportunities, lessons learned, and the positives that can come out of this crisis.

Renewed assessment of the stapled anastomosis with the increasing role of laparoscopic colectomy for colon cancer.

INTRODUCTION: Stapled gastrointestinal anastomosis has gained wide adoption among the surgical community for its ease, speed, and its applicability in laparoscopic surgery. Over the last decade, with the increase in laparoscopic techniques in colon surgery, anastomotic stapling has become the technique of choice for colon cancer surgery at our center. This abstract assesses whether the increasing adoption of anastomotic stapling affected the rate of anastomotic leaks and duration of surgery. METHODS: All patients surgically treated for colon cancer with a primary bowel anastomosis from 2004 through 2011 were included (n = 998). Duration of stay, surgery, and postoperative complication rates was compared between hand-sewn and stapled anastomosis. RESULTS: The number of stapled anastomoses grew significantly from 45.8% in 2004-2007 to 80.3% in 2008-2011 (p < 0.001), and an increasing portion of those is performed in laparoscopic procedures (29.8 to 43.3%; p = 0.01). Surgeries using stapled anastomosis initially took longer, but a decreasing trend (2004-2007: 147.5 min to 2007-2011: 124 min; p < 0.001) along with an increasing duration in hand-sewn surgeries (94-118.5 min; p < 0.01) meant stapled procedures became shorter than hand-sewn procedures by 2009. Complication rates did not differ significantly between groups, with stapled anastomoses having lower percentages of anastomotic leaks (1.6 vs. 2.4%; p = 0.38). By the second half of our research period, the median admission for patients with stapled anastomoses was two days shorter (4 vs. 6 days; p < 0.001), independently of the chosen approach. CONCLUSION: Stapled anastomoses did not increase anastomotic leak rates. If anything, leak rates appeared slightly lower. In addition, stapled anastomoses significantly shortened operation duration. With the benefit of being a tool that facilitates minimally invasive surgery, it is a safe way to improve efficiency, reduce costs, and promote faster and better recovery.

Improving outcomes and cost-effectiveness of colorectal surgery.

In order to truly make an impact on improving the cost effectiveness, and most importantly, the outcomes of patients undergoing colorectal surgery, all aspects of care need to be scrutinized, re-evaluated, and refined. To accomplish this, everything from the way we train surgeons to the adoption of a minimally invasive approach for colorectal disease, along with the use of adjunct intraoperative measures to decrease morbidity and mortality, may all need to be incorporated within an ERAS program. Only then will this approach lead the provider to a patient-centric care plan which can successfully reduce metrics such as morbidity, mortality, and length of stay (even with the obligatory readmission rate) and provide it all at a lower cost of care.

Gender and ethnic disparities in colon cancer presentation and outcomes in a US universal health care setting.

OBJECTIVE: Access to care is a pillar of U.S. healthcare reform and could potentially challenge existing ethnic and gender disparities in care. We present a snapshot of these disparities in surgical colon cancer patients in the largest public hospital in Massachusetts, a state leading in providing universal healthcare, to indicate potential changes that might result from universal care access. METHODS: All surgical colon cancer patients at Massachusetts General Hospital (2004-2011) were included. Baseline characteristics, perioperative, and long-term outcomes were compared. RESULTS: Among 1,071 patients, the 110 (10.3%) minority patients presented with more comorbid (mean Charlson score 0.84 vs. 0.71; P = 0.039), metastatic (21.8% vs. 14%; P = 0.026), and node-positive disease (50% vs. 38.8%; P = 0.014). Women (n = 521; 48.6%) had less screening diagnoses (overall: 17.8% vs. 22.6%; P = 0.049, screening age: 26.4% vs. 32.7%; P = 0.036) with subsequently higher rates of metastatic disease on pathology (11.3% vs. 7.1%, P = 0.02). Multivariate adjustment for baseline staging makes outcome disparities no longer statistically significant. CONCLUSIONS: Significant gender and ethnic disparities subsist at baseline despite long-standing low-threshold healthcare access, although seemingly mitigated by enrollment into high-level care, empowering equal chances for underprivileged groups. The outcomes are also a reminder that universal healthcare will not be a panacea for the deeply rooted and dynamic causes of presentation inequalities.

Retrospective evaluation of elastic stain in the assessment of serosal invasion of pT3N0 colorectal cancers.

Peritoneal involvement is an important adverse prognostic factor in colorectal cancer (CRC) and determines a shift in the pathologic tumor node metastasis stage. Because peritoneal involvement is difficult to identify, use of special stains highlighting the peritoneal elastic lamina and mesothelial surface has been proposed. This study aims to determine whether use of elastic stain or CK7 immunohistochemistry on a single tissue section can refine the level of tumor invasion and determine whether restaging based on this assessment has prognostic significance in pT3N0 CRCs. Elastic stains were applied to 1 block per case from 244 consecutively resected pT3N0M0 CRCs. CK7 was evaluated in a 169-case subset. The elastic lamina was identified in only 101 cases (41%). Of those, 60 cases (24.6%) displayed elastic lamina invasion (ELI). This finding was associated with significantly worse (P<0.001) disease-free survival (DFS) (5-y DFS=60%) and significantly worse (P=0.01) overall survival (OS) (5-y OS=66.7%) compared with patients with no ELI (5-y DFS=87.8%, OS=92.7%) and those for whom no elastic lamina was identified (5-y DFS=82.5%, OS=86.0%). CK7 staining highlighted mesothelial cells in only 27 of 169 cases tested and helped demonstrate serosal invasion in only 5 cases (3%). In summary, the use of a single elastic stain is a useful and inexpensive method to demonstrate peritoneal involvement by tumor and should be considered for routine use in all pT3N0 CRCs. As tumors with ELI have an adverse prognosis, we propose that they should be upstaged compared with pT3N0 tumors without ELI.

Leaks and endoscopic assessment of break of integrity after NOTES gastrotomy: the LEAKING study, a prospective, randomized, controlled trial.

BACKGROUND: Gastric leak testing after natural orifice transluminal endoscopic surgery (NOTES) gastrotomy closure may help reduce the risk of leaks after transgastric procedures. OBJECTIVE: To develop a novel endoscopy-based system to determine the presence of a leak after NOTES gastrotomy and to compare this system prospectively with radiographic leak testing. DESIGN: Prospective, randomized, controlled trial. SETTING: Academic Medical Center laboratory. SUBJECTS: Fifty swine. INTERVENTION: During the pretrial phase, an endoscopic system for the measurement of intragastric pressure was developed. In the trial phase, swine with a NOTES gastrotomy were randomized to endoscopic versus radiographic leak testing. If a leak was demonstrated, the gastrotomy was reclosed by using a second-generation prototype T-anchor system. The primary outcome was leak detection after gastrotomy closure. The secondary outcome variables included necropsy findings, peritoneal fluid analysis, histologic examination, and clinical outcome. RESULTS: Fourteen swine were included in the pretrial phase and 36 in the randomized trial. Swine were survived for a mean of 9 days postoperatively. Endoscopic pressure monitoring demonstrated a reproducible change in intragastric pressure with insufflation; r = 0.735, P = .001 and r = 0.769, P < or = .000 for the total and maximum pressures, respectively. Post-peritoneoscopy, there was a detectable and significant decrease in the mean total and mean maximum pressures versus baseline (P = .006 and P = .009). There was no significant difference between the radiologic and endoscopic arms in leak detection rate (4/18 vs 3/18, respectively, P = .500). Clinical outcomes and mean weight gain were equivalent. There was 1 operative abdominal wall injury and no deaths. LIMITATIONS: Animal study. CONCLUSION: Endoscopic pressure monitoring was reproducible, demonstrated the presence of gastric leak, and was as reliable as contrast-based radiographic leak testing.
