Utility of gastrostomy tube placement at the time of pancreaticoduodenectomy.

PURPOSE: The aim of this study is to investigate the utility of gastrostomy tube (G-tube) placement in reducing delayed gastric emptying (DGE) among patients undergoing pancreaticoduodenectomy (PD). METHODS: We retrospectively reviewed consecutive patients undergoing PD from 2015 to 2020 at our institution. Thirty-day patient outcomes including DGE, length of stay (LOS), reoperation rates, and morbidity were analyzed in patients with or without G-tube placement. RESULTS: 128 patients with resectable pancreatic head cancer (54 females, median age 68.50 [59.00-74.00]) underwent PD (66 had G-tube placement and 62 did not). There was no significant difference in the incidence of DGE (n = 17 vs. n = 17, p = 0.612), and LOS between the groups. Postoperative ileus (p = 0.007) was significantly lower while atrial fibrillation (p = 0.037) was higher among the G-tube group. Gastrostomy-related complications (p = 0.001) developed in ten patients: skin-related complications (n = 6), tube dislodgement (n = 3) and clogging (n = 1). Nine patients required reoperation during index admission (n = 4 vs. n = 5, p = 1.000). There was no difference in 30-day readmissions (n = 7 vs. n = 5, p = 0.471) and no difference in 30 or 90-day mortality. CONCLUSION: Gastrostomy tube placement during index PD did not affect the incidence of DGE. However, patients experienced significant morbidities due to G-tube-related complications. Placement of gastrostomy tubes at the index PD offers no clinical benefits.

Major coronary artery calcifications as predictors of postoperative complications in Ivor Lewis esophagectomies: a five-year retrospective analysis.

BACKGROUND: This study aimed to determine the relationship between preoperative arterial calcifications and postoperative outcomes after Ivor Lewis esophagectomies. METHODS: This was a single-center retrospective review of Ivor Lewis esophagectomies from 2013 to 2018. Preoperative CT imaging was reviewed, and arterial calcifications were graded (absent, minor, or major) in various locations. The primary outcome included major complications (defined by the Clavien-Dindo classification III-V) and the secondary outcomes were 90-day reoperations, readmissions, and mortality. Significant associations (p < 0.05) between calcifications and outcomes on univariable analysis were evaluated using a multivariable logistic regression model (odds ratios, OR; 95% confidence intervals, CI). RESULTS: One hundred patients underwent esophagectomies from 2013 to 2018 (79% male, 90% White, median age 68 years), and 85% were classified as ASA III. Ninety-four patients had accessible preoperative imaging. Arterial calcifications in specific areas were observed: 82 in coronary arteries (major in 33 patients), 54 in the aortic valve, 78 in supra-aortic arteries, 79 in the thoracic aorta, 82 in the abdominal aorta, and 71 in common iliac. Furthermore, 60 patients exhibited celiac axis calcifications, with 40 patients classified as major. Twenty-five patients experienced major complications. Anastomotic leak occurred in two patients, and graft necrosis occurred in one patient. Ninety-day readmission was 10%, reoperation was 12%, and mortality was 4%. On univariable analysis, major coronary artery calcifications were significantly associated with major complications (OR 4.04; 95% CI 1.34-12.16; p = 0.02) and 90-day readmissions (OR 8.20; 95% CI 1.01-68.47; p = 0.04). However, no significant associations were identified between 90-day reoperations or mortality and arterial calcifications. CONCLUSIONS: This study demonstrated that preoperative coronary calcifications increase the risk of postoperative complications, as this may be a surrogate of overall health. Nonetheless, the correlation between splanchnic calcifications and postoperative outcomes needs further exploration.

EAES/SAGES evidence-based recommendations and expert consensus on optimization of perioperative care in older adults.

BACKGROUND: As the population ages, more older adults are presenting for surgery. Age-related declines in physiological reserve and functional capacity can result in frailty and poor outcomes after surgery. Hence, optimizing perioperative care in older patients is imperative. Enhanced Recovery After Surgery (ERAS) pathways and Minimally Invasive Surgery (MIS) may influence surgical outcomes, but current use and impact on older adults patients is unknown. The aim of this study was to provide evidence-based recommendations on perioperative care of older adults undergoing major abdominal surgery. METHODS: Expert consensus determined working definitions for key terms and metrics related to perioperative care. A systematic literature review and meta-analysis was performed using the PubMed, Embase, Cochrane Library, and Clinicaltrials.gov databases for 24 pre-defined key questions in the topic areas of prehabilitation, MIS, and ERAS in major abdominal surgery (colorectal, upper gastrointestinal (UGI), Hernia, and hepatopancreatic biliary (HPB)) to generate evidence-based recommendations following the GRADE methodology. RESULT: Older adults were defined as 65 years and older. Over 20,000 articles were initially retrieved from search parameters. Evidence synthesis was performed across the three topic areas from 172 studies, with meta-analyses conducted for MIS and ERAS topics. The use of MIS and ERAS was recommended for older adult patients particularly when undergoing colorectal surgery. Expert opinion recommended prehabilitation, cessation of smoking and alcohol, and correction of anemia in all colorectal, UGI, Hernia, and HPB procedures in older adults. All recommendations were conditional, with low to very low certainty of evidence, with the exception of ERAS program in colorectal surgery. CONCLUSIONS: MIS and ERAS are recommended in older adults undergoing major abdominal surgery, with evidence supporting use in colorectal surgery. Though expert opinion supported prehabilitation, there is insufficient evidence supporting use. This work has identified evidence gaps for further studies to optimize older adults undergoing major abdominal surgery.

Small Bowel Neuroendocrine Neoplasms-A Review.

ABSTRACT: Neuroendocrine neoplasms (NENs) are rapidly evolving small bowel tumors, and the patients are asymptomatic at the initial stages. Metastases are commonly observed at the time of presentation and diagnosis. This review addresses the small bowel NEN (SB-NEN) and its molecular, histological, and imaging features, which aid diagnosis and therapy guidance. Somatic cell number alterations and epigenetic mutations are studied to be responsible for sporadic and familial SB-NEN. The review also describes the grading of SB-NEN in addition to rare histological findings such as mixed neuroendocrine-non-NENs. Anatomic and nuclear imaging with conventional computed tomography, magnetic resonance imaging, computed tomographic enterography, and positron emission tomography are adopted in clinical practice for diagnosing, staging, and follow-up of NEN. Along with the characteristic imaging features of SB-NEN, the therapeutic aspects of imaging, such as peptide receptor radionuclide therapy, are discussed in this review.

Association of Medicaid expansion with 2-year survival and time to treatment initiation in gastrointestinal cancer patients: A National Cancer Database study.

INTRODUCTION: We evaluated whether Medicaid expansion (ME) was associated with improved 2-year survival and time to treatment initiation (TTI) among patients with gastrointestinal (GI) cancer. METHODS: GI cancer patients diagnosed 40-64 years were queried from the National Cancer Database. Those diagnosed from 2010 to 2012 were considered pre-expansion; those diagnosed from 2014 to 2016 were considered post-expansion. Cox models estimated hazard ratios and 95% confidence intervals (CIs) for 2-year overall survival. Generalized estimating equations (GEE) estimated odds ratios (OR) and 95% CI of TTI within 30- and 90 days. Multivariable Difference-in-Difference models were used to compare expansion/nonexpansion cohorts pre-/post-expansion, adjusting for patient, clinical, and hospital factors. RESULTS: 377,063 patients were included. No significant difference in 2-year survival was demonstrated across ME and non-ME states overall or in site-based subgroup analysis. In stage-based subgroup analysis, 2-year survival significantly improved among stage II cancer, with an 8% decreased hazard of death at 2 years (0.92; 0.87-0.97). Those with stage IV had a 4% increased hazard of death at 2 years (1.04; 1.01-1.07). Multivariable GEE models showed increased TTI within 30 days (1.12; 1.09-1.16) and 90 days (1.22; 1.17-1.27). Site-based subgroup analyses indicated increased likelihood of TTI within 30 and 90 days among colon, liver, pancreas, rectum, and stomach cancers, by 30 days for small intestinal cancer, and by 90 days for esophageal cancer. In subgroup analyses, all stages experienced improved odds of TTI within 30 and 90 days. CONCLUSION: ME was not associated with significant improvement in 2-year survival for those with GI cancer. Although TTI increased after ME for both cohorts, the 30- and 90-day odds of TTI was higher for those from ME compared with non-ME states. Our findings add to growing evidence of associations with ME for those diagnosed with GI cancer.

Process for quality assessment review of societal guidelines-an editorial to accompany "multi-society consensus conference and guideline on the treatment of gastroesophageal reflux disease (GERD)".

BACKGROUND: The SAGES Guidelines Committee has implemented processes for Quality Assessment of SAGES-endorsed guidelines, with the aim of improving the quality of published guidelines. METHODS: We provide details of the processes developed, using standardized tools for assessing the methodological quality of practice guidelines. As an example, we describe the application of our processes to the recent multi-societal GERD consensus guideline. RESULTS: Assessment of the multi-societal GERD consensus guideline by the iterative processes of SAGES Quality Assurance taskforce improved the quality of the final manuscript in all domains of appraisal. These processes are easily applicable to future guidelines. CONCLUSIONS: Such systems will increase the confidence in SAGES recommendations and increase the implementation of SAGES guidelines. By demonstrating the rigor of Quality Assessment, this confidence also extends to a further increase in the assurance of the publications of the Surgical Endoscopy journal.

Surgical approach to microwave and radiofrequency liver ablation for hepatocellular carcinoma and colorectal liver metastases less than 5 cm: a systematic review and meta-analysis.

BACKGROUND: Primary hepatocellular carcinoma (HCC) and colorectal liver metastases (CRLM) represent the two most common malignant neoplasms of the liver. The objective of this study was to assess outcomes of surgical approaches to liver ablation comparing laparoscopic versus percutaneous microwave ablation (MWA), and MWA versus radiofrequency ablation (RFA) in patients with HCC or CRLM lesions smaller than 5 cm. METHODS: A systematic review was conducted across seven databases, including PubMed, Embase, and Cochrane, to identify all comparative studies between 1937 and 2021. Two independent reviewers screened for eligibility, extracted data for selected studies, and assessed study bias using the modified Newcastle Ottawa Scale. Random effects meta-analyses were subsequently performed on all available comparative data. RESULTS: From 1066 records screened, 11 studies were deemed relevant to the study and warranted inclusion. Eight of the 11 studies were at high or uncertain risk for bias. Our meta-analyses of two studies revealed that laparoscopic MW ablation had significantly higher complication rates compared to a percutaneous approach (risk ratio = 4.66; 95% confidence interval = [1.23, 17.22]), but otherwise similar incomplete ablation rates, local recurrence, and oncologic outcomes. The remaining nine studies demonstrated similar efficacy of MWA and RFA, as measured by incomplete ablation, complication rates, local/regional recurrence, and oncologic outcomes, for both HCC and CRLM lesions less than 5 cm (p > 0.05 for all outcomes). There was no statistical subgroup interaction in the analysis of tumors < 3 cm. CONCLUSION: The available comparative evidence regarding both laparoscopic versus percutaneous MWA and MWA versus RFA is limited, evident by the few studies that suffer from high/uncertain risk of bias. Additional high-quality randomized trials or statistically matched cohort studies with sufficient granularity of patient variables, institutional experience, and physician specialty/training will be useful in informing clinical decision making for the ablative treatment of HCC or CRLM.

SAGES/AHPBA guidelines for the use of minimally invasive surgery for the surgical treatment of colorectal liver metastases (CRLM).

BACKGROUND: Colorectal liver metastases (CRLM) occur in roughly half of patients with colorectal cancer. Minimally invasive surgery (MIS) has become an increasingly acceptable and utilized technique for resection in these patients, but there is a lack of specific guidelines on the use of MIS hepatectomy in this setting. A multidisciplinary expert panel was convened to develop evidence-based recommendations regarding the decision between MIS and open techniques for the resection of CRLM. METHODS: Systematic review was conducted for two key questions (KQ) regarding the use of MIS versus open surgery for the resection of isolated liver metastases from colon and rectal cancer. Evidence-based recommendations were formulated using the GRADE methodology by subject experts. Additionally, the panel developed recommendations for future research. RESULTS: The panel addressed two KQs, which pertained to staged or simultaneous resection of resectable colon or rectal metastases. The panel made conditional recommendations for the use of MIS hepatectomy for both staged and simultaneous resection when deemed safe, feasible, and oncologically effective by the surgeon based on the individual patient characteristics. These recommendations were based on low and very low certainty of evidence. CONCLUSIONS: These evidence-based recommendations should provide guidance regarding surgical decision-making in the treatment of CRLM and highlight the importance of individual considerations of each case. Pursuing the identified research needs may help further refine the evidence and improve future versions of guidelines for the use of MIS techniques in the treatment of CRLM.

SAGES/AHPBA guidelines for the use of microwave and radiofrequency liver ablation for the surgical treatment of hepatocellular carcinoma or colorectal liver metastases less than 5 cm.

BACKGROUND: Primary hepatocellular carcinoma (HCC) and colorectal liver metastases (CRLM) represent the liver's two most common malignant neoplasms. Liver-directed therapies such as ablation have become part of multidisciplinary therapies despite a paucity of data. Therefore, an expert panel was convened to develop evidence-based recommendations regarding the use of microwave ablation (MWA) and radiofrequency ablation (RFA) for HCC or CRLM less than 5 cm in diameter in patients ineligible for other therapies. METHODS: A systematic review was conducted for six key questions (KQ) regarding MWA or RFA for solitary liver tumors in patients deemed poor candidates for first-line therapy. Subject experts used the GRADE methodology to formulate evidence-based recommendations and future research recommendations. RESULTS: The panel addressed six KQs pertaining to MWA vs. RFA outcomes and laparoscopic vs. percutaneous MWA. The available evidence was poor quality and individual studies included both HCC and CRLM. Therefore, the six KQs were condensed into two, recognizing that these were two disparate tumor groups and this grouping was somewhat arbitrary. With this significant limitation, the panel suggested that in appropriately selected patients, either MWA or RFA can be safe and feasible. However, this recommendation must be implemented cautiously when simultaneously considering patients with two disparate tumor biologies. The limited data suggested that laparoscopic MWA of anatomically more difficult tumors has a compensatory higher morbidity profile compared to percutaneous MWA, while achieving similar overall 1-year survival. Thus, either approach can be appropriate depending on patient-specific factors (very low certainty of evidence). CONCLUSION: Given the weak evidence, these guidelines provide modest guidance regarding liver ablative therapies for HCC and CRLM. Liver ablation is just one component of a multimodal approach and its use is currently limited to a highly selected population. The quality of the existing data is very low and therefore limits the strength of the guidelines.

The prognostic significance of duodenal wall invasion in pancreatic adenocarcinoma.

OBJECTIVE: The most recent edition of the American Joint Committee on Cancer Staging Manual (AJCC, 8th edition) relies only on tumor size for staging resectable pancreatic adenocarcinoma, and the presence of duodenal wall invasion (DWI) no longer has an impact on staging. However, very few studies have evaluated its significance. In this study, we aim to evaluate the prognostic significance of DWI in pancreatic adenocarcinoma. METHODS: We reviewed 97 consecutive internal cases of resected pancreatic head ductal adenocarcinoma, and clinicopathologic parameters were recorded. All cases were staged according to the 8th edition of AJCC, and the patients were divided into two groups based on the presence or absence of DWI. RESULTS: Out of our 97 cases, 53 patients had DWI (55%). In univariate analysis, DWI was significantly associated with lymphovascular invasion and lymph node metastasis (AJCC 8th edition pN stage). In univariate analysis of overall survival, age > 60, absence of DWI, and African American race were associated with worse overall survival. In multivariate analysis, age > 60, absence of DWI, and African American race were associated with worse progression-free survival and overall survival. CONCLUSION: Although DWI is associated with lymph node metastasis, it is not associated with inferior disease-free/overall survival.

Indocyanine green perfusion assessment of the gastric conduit in minimally invasive Ivor Lewis esophagectomy.

BACKGROUND: Anastomotic leak is a serious complication following esophagectomy. The aim of the study was to report our experience with indocyanine green fluorescence angiography (ICG-FA)-PINPOINT® assisted minimally invasive Ivor Lewis esophagectomy (MILE) and assess factors associated with anastomotic leak. METHODS: We reviewed consecutive patients undergoing MILE from 2013 to 2018. Intraoperative real-time assessment of gastric conduit was performed using ICG-FA with PINPOINT®. Perfusion was categorized as good perfusion (brisk ICG visualization to conduit tip) or non-perfusion (any demarcation along the conduit). RESULTS: 100 patients (81 males, median age 68 [60-72]) underwent MILE for malignancy in 96 patients and benign disease in 4 patients. There were six anastomotic leaks all managed with endoscopic stent placement. There was no intraoperative mortality and no 30-day mortality in leak patients. Patients with a leak were more likely to be overweight with BMI > 25 (100% versus 53%, p = 0.03), have pre-existing diabetes (50% versus 13%, p = 0.04), and have higher intraoperative estimated blood loss (260 mL [95-463] versus 75 mL [48-150], p = 0.03). Anastomotic leaks occurred more frequently in the non-perfusion (67%) versus the good perfusion category (33%, p = 0.03). By multivariable analysis, diabetes (odds ratio [OR] 6.42; p = 0.04) and non-perfusion (OR 6.60; p = 0.04) were independently associated with leak. CONCLUSION: Intraoperative use of ICG-FA may be a useful adjunct to assess perfusion of the gastric conduit with non-perfusion being independently associated with a leak. While perfusion plays an important role in anastomotic integrity, development of a leak is multifactorial, and ICG-FA should be used in conjunction with the optimization of patient and procedural components to minimize leak rates. Prospective, randomized studies are required to validate the interpretation, efficacy, and application of this novel technology in minimally invasive esophagectomies.

Minimally invasive versus open hepatectomy for the resection of colorectal liver metastases: a systematic review and meta-analysis.

BACKGROUND: While surgical resection has a demonstrated utility for patients with colorectal liver metastases (CRLM), it is unclear whether minimally invasive surgery (MIS) or an open approach should be used. This review sought to assess the efficacy and safety of MIS versus open hepatectomy for isolated, resectable CRLM when performed separately from (Key Question (KQ) 1) or simultaneously with (KQ2) the resection of the primary tumor. METHODS: PubMed, Embase, Google Scholar, Cochrane CENTRAL, International Clinical Trials Registry Platform (ICTRP), and ClinicalTrials.gov databases were searched to identify both randomized controlled trials (RCTs) and non-randomized comparative studies published during January 2000-September 2020. Two independent reviewers screened literature for eligibility, extracted data from included studies, and assessed internal validity using the Cochrane Risk of Bias 2.0 Tool and the Newcastle-Ottawa Scale. A random-effects meta-analysis was performed using risk ratios (RR) and mean differences (MD). RESULTS: From 2304 publications, 35 studies were included for meta-analysis. For staged resections, three RCTs and 20 observational studies were included. Data from RCTs indicated MIS having similar disease-free survival (DFS) at 1-year (RR 1.03, 95%CI 0.70-1.50), overall survival (OS) at 5-years (RR 1.04, 95%CI 0.84-1.28), fewer complications of Clavien-Dindo Grade III (RR 0.62, 95%CI 0.38-1.00), and shorter hospital length of stay (LOS) (MD -6.6 days, 95%CI -10.2, -3.0). For simultaneous resections, 12 observational studies were included. There was no evidence of a difference between MIS and the open group for DFS-1-year, OS-5-year, complications, R0 resections, blood transfusions, along with lower blood loss (MD -177.35 mL, 95%CI -273.17, -81.53) and shorter LOS (MD -3.0 days, 95%CI -3.82, -2.17). CONCLUSIONS: Current evidence regarding the optimal approach for CRLM resection demonstrates similar oncologic outcomes between MIS and open techniques, however MIS hepatectomy had a shorter LOS, lower blood loss and complication rate, for both staged and simultaneous resections.

Long-term survival outcomes of esophageal cancer after minimally invasive Ivor Lewis esophagectomy.

OBJECTIVES: The aim of this study was to determine the long-term overall and disease-free survival and factors associated with overall survival in patients with esophageal cancer undergoing a totally minimally invasive Ivor Lewis esophagectomy (MILE) at a safety-net hospital. METHODS: This was a single-center retrospective review of consecutive patients who underwent MILE from September 2013 to November 2017. Overall and disease-free survival were analyzed by Kaplan-Meier estimates, and hazard ratios (HR) were derived from multivariable Cox regression models. RESULTS: Ninety-six patients underwent MILE during the study period. Overall survival at 1, 3, and 5 years was 83.2%, 61.9%, and 55.9%, respectively. Disease-free survival at 1, 3, and 5 years was 83.2%, 60.6%, and 47.5%, respectively. Overall survival (p < 0.001) and disease-free survival (p < 0.001) differed across pathological stages. By multivariable analysis, increasing age (HR, 1.06; p = 0.02), decreasing Karnofsky performance status score (HR, 0.94; p = 0.002), presence of stage IV disease (HR, 5.62; p = 0.002), locoregional recurrence (HR, 2.94; p = 0.03), and distant recurrence (HR, 4.78; p < 0.001) were negatively associated with overall survival. Overall survival significantly declined within 2 years and was independently associated with stage IV disease (HR, 3.29; p = 0.04) and distant recurrence (HR, 5.78; p < 0.001). CONCLUSION: MILE offers favorable long-term overall and disease-free survival outcomes. Age, Karnofsky performance status score, stage IV, and disease recurrence are shown to be prognostic factors of overall survival. Prospective studies comparing long-term outcomes after different MIE approaches are warranted to validate survival outcomes after MILE.

Minimally Invasive Ivor-Lewis Esophagectomy for Esophageal Cancer After Gastric Bypass.

The increasing prevalence of morbid obesity in the United States has been accompanied by a concomitant rise in bariatric surgery to help combat the epidemic. The relationship between obesity and certain cancers, such as esophageal adenocarcinoma, is well established. The need for minimally invasive techniques to treat esophageal cancer in patients with previous bariatric surgery is growing and can present a unique surgical challenge. This report presents the case of a 55-year-old woman with a previous Roux-en-Y gastric bypass who was shown by endoscopy to have an invasive adenocarcinoma located in the distal thoracic esophagus. This necessitated an excision of the thoracic esophagus and the gastric pouch. A laparoscopic and thoracoscopic Ivor-Lewis esophagogastrectomy was performed for this complex patient with esophageal adenocarcinoma. The remnant stomach was fashioned into a gastric conduit using a 60-mm linear stapler with a staple height of 4.1 mm (Echelon, Ethicon Endosurgery, Blue Ash, OH). The reconstruction was performed using a 25-mm Orvil (Covidien, Minneapolis, MN, USA) and EEA 25-mm DST XL (Covidien) to create a circular stapled thoracic esophagogastric anastomosis. A feeding jejunostomy was placed in the residual 130-cm Roux limb. The study demonstrated that minimally invasive esophagectomy is safe and technically feasible with appropriate oncologic outcomes for patients with previous gastric bypass. This cohort of patients will undoubtedly continue to grow in the coming years.

Guidelines for the performance of minimally invasive splenectomy.

BACKGROUND: Minimally invasive splenectomy (MIS) is increasingly favored for the treatment of benign and malignant diseases of the spleen over open access approaches. While many studies cite the superiority of MIS in terms of decreased morbidity and length of stay over a traditional open approach, the comparative effectiveness of specific technical and peri-operative approaches to MIS is unclear. OBJECTIVE: To develop evidence-based guidelines that support clinicians, patients, and others in decisions on the peri-operative performance of MIS. METHODS: A guidelines committee panel of the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) including methodologists used the Grading of Recommendations Assessment, Development and Evaluation approach to grade the certainty of evidence and formulate recommendations. RESULTS: Informed by a systematic review of the evidence, the panel agreed on eight recommendations for the peri-operative performance of MIS for adults and children in elective situations addressing six key questions. CONCLUSIONS: Conditional recommendations were made in favor of lateral positioning for non-hematologic disease, intra-operative platelet administration for patients with idiopathic thrombocytopenic purpura instead of preoperative administration, and the use of mechanical devices to control the splenic hilum. Further, a conditional recommendation was made against routine intra-operative drain placement.

Assessment of the American College of Surgeons National Surgical Quality Improvement Program Calculator in Predicting Outcomes and Length of Stay After Ivor Lewis Esophagectomy: A Single-Center Experience.

BACKGROUND: The American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) calculator is a useful tool used by physicians to better inform patients on the surgical risk of postoperative complications. It makes use of the NSQIP database to derive the chance for several adverse outcomes to occur postoperatively given certain patient's factors. The aim of this study was to assess its applicability in a series of patients undergoing an Ivor Lewis esophagectomy. METHODS: Data from 100 consecutive patients who underwent an Ivor Lewis esophagectomy between September 2013 and November 2017 at our institution were reviewed. Each patient was assessed using the ACS NSQIP surgical risk calculator. Actual events in this group were compared with their particular NSQIP-assessed risk. Logistic regression models were used to compare surgical risk calculator estimates binary outcomes such as incidence of postoperative complications such as cardiac events, renal events, surgical site infection, and death. Mixed linear model was used for length of stay (LOS) duration versus observed LOS. C-statistic was for predictive accuracy each binary outcome and intraclass correlation was used for LOS. RESULTS: C-statistic values were higher than the cutoff (0.75) for surgical site infection and death. The ACS NSQIP risk calculator was poorly predictive of other reported outcomes by the calculator such as cardiac or renal complications. Corroboration between observed LOS and predicted LOS was weak (8 d versus 11 d, respectively, intraclass coefficient 0.04). CONCLUSIONS: This study suggests that the risk calculator is useful for identifying risk of death or surgical site infection but poor at discriminating likelihood of other reported outcomes occurring, such as pneumonia, acute renal failure and cardiac complications for patients who underwent an Ivor Lewis esophagectomy. Estimations for procedure-specific complications for esophagectomy may need reevaluated.

Minimally Invasive Ivor Lewis Esophagectomy (MILE): technique and outcomes of 100 consecutive cases.

BACKGROUND: Esophagectomy is the mainstay of therapy for esophageal cancer but is a complex operation that is associated with significantly high morbidity and mortality rates. The primary aim of this study is to report our perioperative outcomes, and long-term survival of Minimally Invasive Ivor Lewis Esophagectomy (MILE). METHODS: IRB approved retrospective study of 100 consecutive patients who underwent elective MILE from September 2013 to November 2017 at University of Florida, Jacksonville. RESULTS: Primary diagnosis was esophageal cancer (n = 96) and benign esophageal disease (n = 4). Anastomotic leak rate was observed in 6%; 30- and 90-day mortality rates were 2% and 3%, respectively. The mean length of hospital stay was 10.3 days; 87 patients were discharged to home, while 12 patients were discharged to rehabilitation facility, and there was one in-hospital mortality secondary to graft necrosis. At a mean follow-up was 37 months (2-74), the 3- and 5-year overall survivals are 63.9 ± 5.0% (95% CI 53.3-72.7%) and 60.5 ± 5.3% (95% CI 49.4-69.9%), respectively. The 3- and 5-year disease-free survival is 75.0 ± 4.8% (95% CI 64.2-83.0%) and 70.4 ± 5.5% (95% CI 58.0-80.0%). CONCLUSION: MILE can be performed with low perioperative mortality, and favorable long-term overall and disease-free survival.

The effects of neoadjuvant therapy on morbidity and mortality of esophagectomy for esophageal cancer: American college of surgeons national surgical quality improvement program (ACS-NSQIP) 2005-2012.

OBJECTIVE: This study used a multi-center database to evaluate the impact of neoadjuvant therapy on the 30-day morbidity and mortality following esophagectomy for esophageal cancer. METHODS: The NSQIP database was queried for 2005-2012 for patients, who had esophagectomy for esophageal cancer. Patients were divided into two groups: neoadjuvant therapy and esophagectomy only. RESULTS: The neoadjuvant group had a lower rates of sepsis (8% vs. 13%, unadjusted P = 0.004) and acute renal failure (0.4% vs. 2%, unadjusted P = 0.01), and a higher rate of pulmonary embolism (PE) (3% vs. 1%, unadjusted P = 0.04). The adjusted odds of PE for patients, who received neoadjuvant therapy were 2.8 times the odds of PE for patients in the esophagectomy group, controlling for BMI. The association with renal failure was not significant, when one adjusted for race. There was no difference in the rates of reoperation, readmission, stroke, cardiac arrest, MI, surgical site and deep organ infections, anastomosis failure, blood transfusions, DVT, septic shock, pneumonia, UTI, respiratory failure, and 30-day mortality between the two groups. CONCLUSIONS: We conclude that neoadjuvant therapy followed by esophagectomy for esophageal cancer does not have a negative impact on 30-day mortality. Neoadjuvant therapy is associated with increased odds of PE. J. Surg. Oncol. 2017;115:296-300. © 2016 Wiley Periodicals, Inc.

Thoracoscopic management of volvulus of the gastric conduit following minimally invasive Ivor-Lewis esophagectomy.

BACKGROUND: We present a case of emergent thoracoscopic management of volvulus of the gastric conduit following minimally invasive Ivor-Lewis esophagectomy. The patient is a 69-year-old Caucasian male with a history of adenocarcinoma of the lower third of the esophagus. Initial presentation was dysphagia with solid foods, which progressed in severity until he was unable to swallow anything. EUS demonstrated a partially obstructing mass at 33 cm; biopsy revealed poorly differentiated adenocarcinoma, stage T3N2Mx. PET scan did not reveal any metastatic disease. Preoperative management included neo-adjuvant chemoradiation therapy (5-FU and cisplatin) and early placement of a jejunal feeding tube. Intra-operative leak test was performed as a matter of routine following completion of the esophagogastric anastomosis. A nasogastric tube was placed intra-operatively and removed on POD2 according to our standard pathway. Postoperatively, the patient progressed without difficulty to POD4, when we routinely obtain an upper GI swallow study. This demonstrated a lack of transit of contrast through the distal neo-esophagus. Follow-up endoscopy revealed volvulus of the gastric conduit with obliteration of the lumen. METHOD: We immediately took the patient to the OR for thoracoscopic detorsion, which we accomplished successfully by entering the existing trochar sites and using blunt dissection.␣Upon entering the thoracic cavity, the staple line that had been oriented anteriorly was now posterior. Attachments were gently teased away from the chest wall and the conduit was detorsed and anchored to the chest wall in the correct orientation with silk suture. Intra-operative endoscopy demonstrated a patent conduit. RESULTS: Postoperative upper GI fluoroscopy now showed good transit of contrast. The patient continued to improve and was eventually advanced to mechanical soft diet and discharged on postoperative day 9. CONCLUSIONS: Early intervention is indicated in cases of volvulus of the gastric conduit following Ivor-Lewis esophagectomy.
