ABSTRACT
BACKGROUND: Sleeve gastrectomy (SG) is the most commonly performed metabolic and bariatric surgery (MBS) procedure. Technical considerations related to the performance of SG are well established and reported in the literature but not in relation to robotic-assisted (RA) SG. We report the results of the first modified Delphi consensus-building exercise addressing technical considerations of RA da Vinci (dV) SG. OBJECTIVES: Develop best practices for the performance of robotic-assisted da Vinci sleeve gastrectomy. SETTING: Survey based consensus statement. METHODS: A consensus building committee (CBC) was created comprising 10 experts in the field of RA surgery and MBS based on strict selection criteria. The CBC developed 49 consensus statements which were then shared with 240 experts in RA surgery. Our stopping criterion was stability in responses (≤15%). The consensus cut point was 70%. RESULTS: The overall response rate was 49%. In the first round of voting, there was consensus agreement on 25 statements (51%), consensus disagreement on 14 (28%), and no consensus on the remaining statements (21%). In the second round of voting, we reached agreement on 3 additional statements. Experts recommended the use of the number of pauses generated by the stapler to guide choice of staple height (91.2%) and to upsize the staple height when using buttressing (92%). There was also consensus (81.4%) that the use of the closed staple height of 1.00 mm (white) is acceptable and that stapling of the antrum using a 1.5-mm staple (blue load) is also acceptable (73%). CONCLUSIONS: Collective expert opinion structured through a modified Delphi consensus statement presents a practical guide for surgeons interested in performing dV-SG.
ABSTRACT
PURPOSE: Metabolic and bariatric surgery (MBS) is presently the most evidence-based, effective treatment of obesity. Nevertheless, only half of the eligible individuals who are referred for this procedure complete it. This study aims to investigate the association between social support and MBS completion, considering race and ethnicity. METHODS: In this prospective cohort study, 413 participants were enrolled between 2019 and 2022. Using the 19-item Brief Family Relationship Scale, which comprises three subscales (eight-item Cohesion subscale, four-item Expressiveness subscale, and seven-item Conflict subscale), the quality of family relationship functioning was assessed. Multivariable logistic regression models were used to determine the association between MBS completion and social support status, adjusting for variables including race, ethnicity, age, gender, body mass index, and insurance. RESULTS: The mean age of the sample was 47.55 years (SD 11.57), with 87% of the participants being female and 39% non-Hispanic White. Nearly 35% of participants (n = 145) completed MBS. Multivariable logistic regression analysis showed overall cohesion (adjusted odds ratio [aOR], 1.52 [95% CI, 1.15-2.00]; p = .003) and overall expressiveness (aOR, 1.58 [95% CI, 1.22-2.05]; p < .001) were associated with higher odds of pursuing MBS. There was no significant interaction between overall cohesion, expressiveness, conflict, and race/ethnicity (p = .61, p = .63, p = .25, respectively). CONCLUSION: The findings indicated that there is a link between family-based social support and MBS completion, regardless of race and ethnicity. Future research should continue to explore the complex interplay between family dynamics and MBS outcomes, considering cultural variations to enhance the effectiveness of obesity interventions within diverse communities.

BACKGROUND: Less than 50% of eligible candidates who are referred complete Bariatric Metabolic Surgery (BMS). The factors influencing the decision to complete BMS, particularly how these factors vary across different racial and ethnic groups, remain largely unexplored. METHODS: This prospective cohort study included adult patients referred to a bariatric surgeon or obesity medicine program between July 2019-September 2022. Sociodemographic characteristics, body mass index (BMI), anxiety, depression, body appreciation, and patient-physician relationship information were collected via survey and electronic health records. The association between BMS completion and potential decision-driving factors was examined using Classification and Regression Tree (CART) analysis. RESULTS: A total of 406 BMS -eligible patients participated in the study (mean [SD] age: 47.5 [11.6] years; 87.2% women; 18.0% Hispanic, 39% non-Hispanic Black [NHB], and 39% non-Hispanic White [NHW]; mean [SD] BMI: 45.9 [10.1] kg/m2). A total of 147 participants (36.2%) completed BMS. Overall, the most influential factor driving the decision to complete BMS was younger age (< 68.4 years), higher patient satisfaction, and BMI (≥ 38.0 kg/m2). Hispanic participants prioritized age (< 55.4 years), female sex, and body appreciation. For NHB participants, the highest ranked factors were age < 56.3 years, BMI ≥ 35.8 kg/m2, and higher patient satisfaction. For NHW patients, the most influential factors were age (39.1 to 68.6 years) and higher body appreciation. CONCLUSION: These findings highlight racial and ethnic group differences in the factors motivating individuals to complete BMS. By acknowledging these differences, healthcare providers can support patients from different backgrounds more effectively in their decision-making process regarding BMS.

BACKGROUND: Mental health conditions including depression and anxiety are often prevalent among metabolic and bariatric surgery (MBS) patients, but it is not known if these conditions predict the decision to complete the procedure and if this varies by race and ethnicity. This study aimed to determine if depression and anxiety are associated with MBS completion among a race/ethnically diverse sample of patients. METHODS: This prospective cohort study included participants who were referred to an obesity program or two MBS practices between August 2019 and October 2022. Participants completed the Mini International Neuropsychiatric Interview (MINI) instrument to determine history of anxiety and/or depression, as well as MBS completion status (Y/N). Multivariable logistic regression models determined the odds of MBS completion by depression and anxiety status adjusting for age, sex, body mass index, and race/ethnicity. RESULTS: The sample consisted of 413 study participants (87 % women, 40% non-Hispanic White, 39% non-Hispanic Black, and 18% Hispanic). Participants with a history of anxiety were less likely to complete MBS (aOR = 0.52, 95% CI = 0.30-0.90, p = 0.020). Women had increased odds of a history of anxiety (aOR = 5.65, 95% CI = 1.64-19.49, p = 0.006) and of concurrent anxiety and depression (aOR = 3.07, 95% CI = 1.39-6.79, p = 0.005) compared to men. CONCLUSIONS: Results showed that participants with anxiety were 48% less likely to complete MBS compared to those without anxiety. Additionally, women were more likely to report a history of anxiety with and without depression versus men. These findings can inform pre-MBS programs about risk factors for non-completion.

PURPOSE: Metabolic and bariatric surgery (MBS) is an evidence-based safe, effective treatment for obesity. However, only half of referred or eligible persons complete the procedure for unknown reasons. The proposed study examined the association between the degree of body appreciation and the decision to complete MBS by ethnicity. METHODS: This prospective cohort study included 409 participants who had been referred to a bariatric surgeon or an obesity medicine program between August 2019 and May 2022. Participants completed a survey about health behaviors and psychosocial characteristics, including body appreciation by MBS completion status (Y/N). Multivariate logistic regression models generated adjusted odd ratios (aOR) and 95% confidence intervals (CIs) of body appreciation among MBS completers vs. non-completers. RESULTS: The sample mean age was 47.18 years (SD 11.63), 87% were female. 39.6% identified as non-Hispanic White (NHW), 38.5% as non-Hispanic Black (NHB), and 17.6% as Hispanic. Over a third of the sample (31.05%, n = 127) completed MBS. "Often" experiencing body appreciation was the most significant predictor of MBS completion (aOR: 28.19, 95% CI: 6.37-124.67, p-value < 0.001), followed by "Sometimes" (aOR: 20.47, 95% CI: 4.82-86.99, p-value < 0.001) and "Always" (aOR: 13.54, 95% CI: 2.55-71.87, p-value < 0.01) after controlling for sex, age, and race/ethnicity. There was not a significant interaction between body appreciation and race/ethnicity (p-value = 0.96). CONCLUSION: Results showed a significant association between body appreciation and MBS completion, controlling for sex, age, and race/ethnicity. MBS clinical settings may want to assess body appreciation as a pre-operative screener among ethnically diverse patients.

INTRODUCTION: The science of telemedicine has shown great advances over the past decade. However, the field needs to better understand if a change in care delivery from in-person to telehealth as a result of the COVID-19 pandemic will yield durable patient engagement and health outcomes for patients with obesity. The objective of this study was to examine the association of mode of healthcare utilization (telehealth versus in-person) and sociodemographic factors among patients with obesity during the COVID-19 pandemic. METHODS: A retrospective medical chart review identified patients with obesity from a university outpatient obesity medicine clinic and a community bariatric surgery practice. Patients completed an online survey (1 June 2020-24 September 2020) to assess changes in healthcare utilization modality during subsequent changes in infection rates in the geographic area. Logistic regression analysis examined the association of mode of healthcare utilization and key sociodemographic characteristics. RESULTS: A total of 583 patients (87% female, mean age 51.2 years (standard deviation 13.0), mean body mass index 40.2 (standard deviation 6.7), 49.2% non-Hispanic white, 28.7% non-Hispanic black, 16.4% Hispanic, 7% other ethnicity, 33.1% completed bariatric surgery) were included. Adjusted logistic regression models showed older age was inversely associated with telehealth use (adjusted odds ratio = 0.58, 95% confidence interval 0.34-0.98) and non-Hispanic black were more likely to use telehealth compared to non-Hispanic white (adjusted odds ratio = 1.72, 95% confidence interval 1.05-2.81). CONCLUSIONS: The COVID-19 pandemic is impacting access to healthcare among patients with obesity. Telehealth is an emerging modality that can maintain healthcare access during the pandemic, but utilization varies by age and ethnicity in this high-risk population.

Importance: Metabolic and bariatric surgery (MBS) is an effective and safe treatment for obesity and its comorbidities, but less than 50% of those who are eligible and referred for MBS complete the procedure. The patient-physician relationship could be a decisive factor in the decision to complete MBS; however, this relationship has not been explored, particularly among racially and ethnically diverse populations. Objective: To examine the association between patient-reported satisfaction with their patient-physician relationship and MBS completion by self-reported racial and ethnic group. Design, Setting, and Participants: This prospective cohort study included 408 patients who were referred to a bariatric surgeon or obesity medicine program between July 24, 2019, and May 19, 2022. Exposure: Patient satisfaction with their physician was measured by 7 dimensions (general satisfaction, technical quality, interpersonal manner, communication, financial aspects, time spent with physician, and accessibility and convenience) using the Patient Satisfaction Questionnaire Short Form. Main Outcomes and Measures: Completion status for MBS (yes or no). Results: A total of 408 patients (mean [SD] age, 47.3 [11.6] years; among 366 with data available, 317 [86.6%] women and 49 [13.4%] men) were included in the study. Of 363 patients with data available on race and ethnicity, 66 were Hispanic/Latinx (18.2%), 136 (37.5%) were non-Hispanic Black, 146 (40.2%) were non-Hispanic White, and 15 (4.1%) were other race or ethnicity. A total of 124 patients (30.4%) completed MBS. Overall, the mean (SD) patient satisfaction score was significantly greater in MBS completers vs noncompleters (3.86 [0.56] vs 3.61 [0.64]; P < .001). Multivariable logistic regression analysis showed technical quality was the most significant factor for MBS completion (adjusted odds ratio [aOR], 1.99 [95% CI, 1.24-3.19]), followed by communication (aOR, 1.78 [95% CI, 1.16-2.72]) and accessibility and convenience (aOR, 1.61 [95% CI, 1.03-2.53]). The interaction between racial and ethnic groups and patient satisfaction was not significant (eg, mean [SD] score for Hispanic/Latinx completers, 3.95 [0.55] vs 3.77 [0.60] for non-Hispanic White completers; P = .46 for interaction). Conclusions and Relevance: These findings suggest that there is an association between patient satisfaction with the patient-physician relationship and the decision to complete MBS regardless of race and ethnicity. These findings have important implications for strategies to improve the proportion of qualified patients who complete MBS to achieve improved health outcomes.

OBJECTIVE: The aim of this study was to examine the relationships between body weight changes, health behaviors, and mental health in adults with obesity during the second year of the COVID-19 pandemic. METHODS: Between March 1, 2021, and November 30, 2021, adults from three obesity practices completed an online survey. The primary outcomes were ≥ 5% of body weight change since March 2020 and associated health behaviors and mental health factors. RESULTS: The sample (n = 404) was 82.6% female (mean age 52.5 years, mean BMI 43.3 kg/m2 ). Mean weight change was + 4.3%. Weight gain ≥ 5% was reported by 30% of the sample, whereas 19% reported ≥ 5% body weight loss. The degree of both weight gain and weight loss correlated positively with baseline BMI. Eighty percent of the sample reported difficulties with body weight regulation. Those who gained ≥ 5% versus those who lost ≥ 5% body weight were more likely to report higher levels of stress, anxiety, and depression; less sleep and exercise; less healthy eating and home-cooked meals; and more takeout foods, comfort foods, fast foods, overeating, and binge eating. CONCLUSIONS: Weight gain in adults with obesity during the COVID-19 pandemic is associated with higher baseline BMI, deteriorations in mental health, maladaptive eating behaviors, and less physical activity and sleep. Further research is needed to identify effective interventions for healthier minds, behaviors, and body weight as the pandemic continues.

PURPOSE: Robotic approaches have been steadily replacing laparoscopic approaches in metabolic and bariatric surgeries (MBS); however, their superiority has not been rigorously evaluated. The main goal of the study was to evaluate the 5-year utilization trends of robotic MBS and to compare to laparoscopic outcomes. METHODS: Retrospective analysis of 2015-2019 MBSAQIP data. Kruskal-Wallis test/Wilcoxon and Fisher's exact/chi-square were used to compare continuous and categorical variables, respectively. Generalized linear models were used to compare surgery outcomes. RESULTS: The use of robotic MBS increased from 6.2% in 2015 to 13.5% in 2019 (N= 775,258). Robotic MBS patients had significantly higher age, BMI, and likelihood of 12 diseases compared to laparoscopic patients. After adjustment, robotic MBS patients showed higher 30-day interventions and 30-day readmissions alongside longer surgery time (26-38 min). CONCLUSION: Robotic MBS shows higher intervention and readmission even after controlling for cofounding variables.

PURPOSE: The impact of the COVID-19 pandemic on behavioral issues among those who have completed bariatric surgery (BS) is not well described in ethnically diverse populations. The aim of this study was to compare the impact of COVID-19 lockdown orders and after lockdown orders were lifted on substance use, mental health, and weight-related behaviors among a sample of post-BS adults. MATERIALS AND METHODS: A retrospective medical chart review identified BS patients from one university-based obesity medicine clinic and two BS practices. An online non-anonymous survey was implemented in two phases: during lockdown (April 1-May 31, 2020) and after lockdown orders were lifted (June 1, 2020-September 30, 2020) to obtain information about the COVID-19 pandemic's impact on BS patients. RESULTS: A total of 189 (during lockdown=39, post-lockdown=150) participants (90.4% female, mean age 52.4 years, SD 11.1, 49.8% non-Hispanic White, 30.6% non-Hispanic Black, 16.1% Hispanic) participated. Lockdown participants were more likely to have sleep problems (74.3% vs. 56.1%, P=.039) and feel anxious (82.0% vs. 63.0%, P=.024) versus post-lockdown participants. A majority (83.4%) reported depression in both lockdown/post-lockdown. Post-lockdown participants were more than 20 times more likely to report substance use compared those in lockdown (aOR 20.56, 95% CI 2.66-158.4). CONCLUSIONS AND RELEVANCE: The COVID-19 pandemic is having a substantial negative impact on substance use, mental health, and weight-related health behaviors in diverse BS patients. These findings have important implications for post-BS patient care teams and may suggest the integration of screening tools to identify those at high risk for behavioral health issues.

Studies have shown the negative impact of COVID-19 lockdown orders on mental health and substance use in the general population. The aim of this study was to examine the impact of the COVID-19 pandemic onsubstance use, mental health and weight-related behaviors in a sample of adults with obesity after lockdown orders were lifted (June-September 2020). A retrospective medical chart review identified patients with obesity from one university-based obesity medicine clinic, and two metabolic and bariatric surgery (MBS) practices. Patients who completed an online survey from June 1, 2020 to September 30, 2020 were included. The primary outcome measure was substance use (various drugs, alcohol, tobacco). Substance use and mental health survey questions were based on standardized, validated instruments. A total of 589 patients (83.3% female, mean age 53.6 years [SD 12.8], mean BMI 35.4 [SD 9.1], 54.5% Non-Hispanic white, 22.3% post-MBS) were included. Seventeen patients (2.9%) tested positive for SARS-CoV-2 and 13.5% reported symptoms. Nearly half (48.4%) of the sample reported recreational substance use and 9.8% reported increased use since the start of the pandemic. There was substantial drug use reported (24.3% opioids, 9.5% sedative/tranquilizers, 3.6% marijuana, and 1% stimulants). Patients who reported stockpiling food more (adjusted Odds Ratio [aOR] 1.50, 95% CI 1.03-2.18), healthy eating more challenging (aOR 1.47, 95% CI 1.01-2.16), difficulty falling asleep (aOR 1.64, 95% CI 1.14-2.34), and anxiety (aOR 1.47, 95% CI 1.01-2.14) were more likely to report substance use versus non-users. Results here show that the COVID-19 pandemic is having a deleterious impact on substance use, mental health and weight-related health behaviors in people with obesity regardless of infection status.

How the impact of the COVID-19 stay-at-home orders is influencing physical, mental and financial health among vulnerable populations, including those with obesity is unknown. The aim of the current study was to explore the health implications of COVID-19 among a sample of adults with obesity. A retrospective medical chart review identified patients with obesity from an obesity medicine clinic and a bariatric surgery (MBS) practice. Patients completed an online survey from April 15, 2020 to May 31, 2020 to assess COVID-19 status and health behaviours during stay-at-home orders. Logistic regression models examined the impact of these orders on anxiety and depression by ethnic group. A total of 123 patients (87% female, mean age 51.2 years [SD 13.0]), mean BMI 40.2 [SD 6.7], 49.2% non-Hispanic white (NHW), 28.7% non-Hispanic black, 16.4% Hispanic, 7% other ethnicity and 33.1% completed MBS were included. Two patients tested positive for severe acute respiratory syndrome coronavirus 2 and 14.6% reported symptoms. Then, 72.8% reported increased anxiety and 83.6% increased depression since stay-at-home orders were initiated. Also 69.6% reported more difficultly in achieving weight loss goals, less exercise time (47.9%) and intensity (55.8%), increased stockpiling of food (49.6%) and stress eating (61.2%). Hispanics were less likely to report anxiety vs NHWs (adjusted odds ratios 0.16; 95% CI, 0.05-0.49; P = .009). Results here showed the COVID-19 pandemic is having a significant impact on patients with obesity regardless of infection status. These results can inform clinicians and healthcare professionals about effective strategies to minimize COVID-19 negative outcomes for this vulnerable population now and in post-COVID-19 recovery efforts.

BACKGROUND: The robotic approach to an inguinal hernia has not been compared head to head with the open and laparoscopic techniques in randomized controlled trials. Furthermore, long-term outcomes for robotic inguinal hernia repair (RHR) are lacking. In this study, we compared laparoscopic inguinal hernia repair (LHR) and RHR with open inguinal hernia repair (OHR) in veteran patients performed by surgeons most familiar with each approach. METHODS: A retrospective single-institution analysis of 1299 inguinal hernia repairs performed at the VA North Texas Health Care System between 2005 and 2017 was undertaken. Three surgeons performed the operations, each an expert in one approach, and there was no crossover in techniques. A total of 1100 OHRs, 128 LHRs, and 71 RHRs were performed. Univariable analysis was undertaken to determine associations between techniques and outcomes (OHR versus LHR; OHR versus RHR; LHR versus RHR). Setting complications as a dependent variable, multivariable analyses were undertaken to determine an association with complications as well as independent predictors of complications. RESULTS: Patient demographics were similar among groups except for age that was higher in the OHR cohort. The average follow-up was 5.2 ± 3.4 y. In the present report, recurrence was associated with a higher rate in the RHR versus OHR (5.6% versus 1.7%; P < 0.02), but not in the LHR versus OHR (3.9% versus 1.9%; P = 0.09). Inguinodynia was more likely to occur in both the LHR and RHR compared with the OHR (9.4% and 14.1 versus 1.5%; both P's < 0.001). Urinary retention was also more common in the LHR and RHR than in the OHR (5.5% and 5.6% versus 1.8%, both P's < 0.05) as was the rate of overall complications (34.4% and 38.0% versus 11.2%, both P's < 0.001). Multivariable regression analysis showed femoral hernias, ASA, serum albumin, operative room time, a recurrent hernia, and the minimally invasive approaches were independent predictors of overall complications. CONCLUSIONS: Outcomes in the OHR cohort were, in general, superior compared with both the LHR and RHR. However, these strategies should be viewed as complementary. The best approach to an inguinal hernia repair rests on the specific expertise of the surgeon.

BACKGROUND: Bariatric surgery is known to decrease weight and the prevalence of comorbidities, but there is little evidence on the differential effect of Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) on the remission of the aggregate outcome, metabolic syndrome, 4 years after surgery. The purpose of this study was to determine the effectiveness of RYGB and SG on metabolic syndrome in veterans. METHODS: We retrospectively reviewed consecutive patients who underwent SG and RYGB at the Dallas Veterans Affairs Medical Center from 2003 to 2012. We determined the effect of both the operations on the remission of metabolic syndrome, its individual components, and medium-term morbidity and mortality. A sensitivity analysis was performed using propensity matching. RESULTS: A total of 266 patients were identified (159 RYGB and 107 SG) with 96% follow-up after 4 years. The mean age of the cohort was 51.4 years; the majority of patients were male (59%) and Caucasian (69%). RYGB patients had a greater mean body mass index and were more likely to have hypertension or hypertriglyceridemia. RYGB was associated with a similar metabolic syndrome remission to SG (37.6% vs 26.8%; P=0.09). The percentage of weight loss was 26.5% after RYGB and 10.8% after SG at 4 years post operation (P<0.01). Predictors of metabolic syndrome persistence were male gender, type 2 diabetes, and low high-density lipoprotein. While both the operations were associated with similar mortality (RYGB 4.4%, SG 2.8%; P=0.74), RYGB was associated with a greater rate of morbidity. CONCLUSION: RYGB and SG seem to be associated with similar remission rates of metabolic syndrome at 4 years. RYGB yields greater weight loss with greater medium-term complications.
ABSTRACT
OBJECTIVE: For patients with pancreatic cancer, the identification of reliable predictors of their outcomes could be invaluable for directing the managements. This study aimed to identify clinical and laboratory factors that could be used to predict early (≤6 months) or late (>6 months) mortality. METHODS: Medical records of patients diagnosed with pancreatic cancer in the VA North Texas Health Care System from 2005 to 2010 were retrospectively reviewed. Univariate and multivariate analyses (MVA) were performed and the utility of cancer antigen 19-9 (CA19-9) test was explored. RESULTS: Altogether 109 patients with pancreatic cancer, 89.0% of whom were with adenocarcinoma, were divided into early (n = 62) and late (n = 47) mortality groups. Kaplan-Meier analysis revealed a median survival of 154 days [95% confidence interval (CI) 93-194 days]. On MVA, abdominal pain (OR = 10.6, P = 0.009) and large tumor size (OR = 2.4, P = 0.028) were significantly associated with early mortality, while palliative chemotherapy (OR = 0.048, P = 0.001) and neuroendocrine tumor (OR = 0.009, P = 0.024) were significantly associated with late mortality. Subgroup analyses of adenocarcinoma and late-stage patients revealed similar results. Serum CA19-9 performed poorly as a prognostic indicator in both groups (P = 0.43), in metastatic disease at diagnosis (P = 0.32) and after treatment (P = 0.65). CONCLUSIONS: Abdominal pain and large tumor size portends a poor prognosis in patients with pancreatic cancer. Palliative chemotherapy and surgical intervention may prolong the patient's survival. CA19-9 is not universally reliable for predicting metastasis, survival, or the responses to chemotherapy.

Walled-off pancreatic necrosis is a known complication of acute pancreatitis and requires intervention if symptomatic or complicated. Laparoscopic cystogastrostomy as a minimally invasive surgical intervention has been well-described in surgical literature but data on a robotic approach is limited. Here we report a case of robotic cystogastrostomy and debridement of walled-off pancreatic necrosis in a patient with a history of severe biliary pancreatitis.

In adult patients, removal of the entire jejunum and ileum (a near total enterectomy (NTE)) is considered a non-survivable event as patients undergoing this procedure might also suffer from an underlying illness that will lead to bowel necrosis such as septic or cardiac shock and respiratory failure. Parenteral nutrition (PN) dependency with its associated complications and quality of life issues further complicates management decisions in this group of patients. In the following report, we discuss our institutional experience with NTE and present a comprehensive review of the literature with patients undergoing NTE with the establishment of bowel continuity and successful outcomes even in cases dating as far back as the 1950s, over a decade prior to the implementation of PN. Review of the literature revealed 26 cases of NTE. Most of these patients are young (46.7 years old), and 57 % are women. These patients were reported to be alive at 21 months of follow-up. In this report, we present an individual 51 months following NTE. We also document the oldest patient receiving an NTE (76 years old). Both of these patients are alive on home PN. In cases where there is hemodynamic stability and patients request to continue with further care, the possibility of a NTE with bowel continuity and life-long PN might be entertained.

HYPOTHESIS: Evaluation of 12 or more lymph nodes (LNs) with colorectal cancer (CRC) resection may not improve detection of stage III disease. DESIGN: Retrospective review after intervention. SETTING: Community teaching hospital. PATIENTS: We evaluated 701 consecutive operative CRC cases ascertained from our Cancer Registry. INTERVENTION: Patients undergoing resection before (n = 553) a multidisciplinary initiative emphasizing the importance of LN counts were compared with those undergoing operation afterward (n = 148). MAIN OUTCOME MEASURES: Number of LNs evaluated, proportion of patients with stage III disease, and proportion of patients with N1 vs N2 disease. RESULTS: Demographic, tumor, and treatment variables were similar for both groups, except for younger age, fewer white patients, and more laparoscopic resections in the late period. Lymph node counts increased from a mean (SEM [median]) of 12.8 (0.3 [12]) to 17.3 (0.7 [16]) (P < .001), with 53.0% of the early vs 71.6% of the late patients having at least 12 LNs examined. The proportion diagnosed as having stage III CRC was 204 of 553 (36.9%) for the early group vs 48 of 148 (32.4%) for the late group (P = .31). Among patients with positive LNs, the distribution of N1 and N2 disease was unchanged (early, 50.5% N1 and 49.5% N2; late, 54.2% N1 and 45.8% N2; P = .54). CONCLUSIONS: Increased LN retrieval does not identify a greater number of patients with stage III CRC nor does it increase the proportion of patients with positive LNs with N2 disease. Our data suggest that harvest of at least 12 LNs as a quality or performance measure appears unfounded.
