RESUMO
BACKGROUND AND OBJECTIVES: Neoadjuvant chemotherapy (NAC) is becoming favored for all pancreatic adenocarcinoma (PDAC). Patients with seemingly resectable disease infrequently still display vascular involvement intraoperatively. Outcomes following NAC versus upfront surgery in patients undergoing pancreaticoduodenectomy (PD) with vascular resection are unknown. METHODS: We performed a retrospective cohort study of PDAC patients who underwent PD with vascular resection between January 1, 2013, to December 31, 2020, within a single academic center. Clinicopathologic characteristics and disease-free survival (DFS) were compared between NAC versus upfront surgery cohorts using the Kaplan-Meier estimate and Cox proportional-hazards regression model. RESULTS: Eighty-one patients who underwent PD with vascular resection for PDAC were included. Forty-six patients (56%) received NAC. The NAC cohort more often had pathologic N0 status (47.8% vs. 8.6%, p < 0.001), had decreased vascular invasion (11% vs. 40%, p = 0.002), and completed chemotherapy (80% vs. 40%, p < 0.01). The NAC cohort demonstrated improved DFS (40.5 vs. 14.3 months, p = 0.007). In multivariable analysis, NAC remained independently associated with increased DFS (HR = 0.48, p = 0.02). CONCLUSIONS: NAC was associated with improved clinicopathologic outcomes and DFS in PD with vascular resection. These findings demonstrate the advantage of NAC in PDAC patients undergoing PD with vascular resection.

BACKGROUND: Duodenal neuroendocrine tumors (dNETs) are rare, and their management is not well-defined. National Comprehensive Cancer Network (NCCN) guidelines recommend surgical resection of large dNETs (> 2 cm) and endoscopic resection of small tumors (< 2 cm). We compared the survival outcomes between surgical and endoscopic resection in various dNET sizes. METHODS: A retrospective cohort study was conducted using patient data from Surveillance, Epidemiology, and End Results Program (SEER) database. Variables analyzed included age, tumor size, grade, stage, and lymph node status. Disease-specific survival (DSS) was compared for endoscopic and surgical groups in dNET size strata: 0-0.5, 0.5-1, 1-2, 2-3, and > 3 cm. Kaplan-Meier and multivariable Cox proportional hazards models were used for survival analysis. RESULTS: The study included 465 patients, with 124 (26.7%) undergoing surgical resection. The average age was 61.9 years, and tumor sizes ranged from 0.1 to 10.5 cm. Endoscopic resection had 40.5% of tumors between 0 and 0.5 cm, while surgery had only 21% (p < 0.001). In the surgical cohort, 79.8% had grade 1 tumors compared to 88.3% in the endoscopy group (P = 0.024). Among surgically resected cases, 48.4% (60 patients) had lymph node involvement. Age, tumor size, grade, and stage did not significantly predict survival after surgical resection. Stratified by tumor size, no difference in DSS was observed between surgery and endoscopy groups. CONCLUSIONS: Endoscopic resection demonstrated similar survival outcomes to surgical resection across dNET sizes in this national analysis. Given the risks and the lack of survival benefits for surgery, endoscopic resection may be beneficial for both small and large tumors. Further studies are warranted to validate the current NCCN guidelines.

BACKGROUND: Pancreaticoduodenectomy (PD) is complex procedure with high morbidity in the elderly. This retrospective study aimed to compare post-operative outcomes in patients ≥75 years of age who underwent robot-assisted (RA)PD and open PD. METHODS: We analyzed 2502 patients ≥75 years of age who underwent PD from 2015 to 2018 in the National Surgical Quality Improvement Program (NSQIP) database. RAPD and open PD patients were propensity score matched 1:5 to assess the 30-day outcomes of interest: postoperative complications, length of stay, discharge destination, and readmissions. RESULTS: Of 725 matched patients, 110 underwent RAPD, 615 OPD, and 12 were converted to an open operation. Post-operative outcomes were largely similar between cohorts. RAPD was associated a shorter length of stay (median 8 days, interquartile range [IQR] 6 to 11) than OPD (median 8 days, IQR 7 to 13) (p = 0.003). However, RAPD was associated with more readmissions (28.1% vs. 17.7%; p = 0.02). CONCLUSIONS: RAPD in patients ≥75 years of age appears to be safe and has a similar complication profile to open PD. Randomized or well-designed prospective matched studies are needed to confirm these findings.

INTRODUCTION: Implementation of robot-assisted procedures is growing. Utilization within the country's largest healthcare network, the Veterans Health Administration, is unclear. METHODS: A retrospective cohort study using data from the Department of Veterans Affairs Corporate Data Warehouse from January 2015 through December 2019. Trends in robot utilization for cholecystectomy, ventral hernia repair, and inguinal hernia repair were characterized nationally and regionally by Veterans Integrated Services Network. Patients, who underwent laparoscopic repairs for these procedures and open hernia repairs, were included to determine proportion performed robotically. RESULTS: We identified 119,191 patients, of which 5689 (4.77%) received a robotic operation. The proportion of operations performed robotically increased from 1.49% to 10.55% (7.08-fold change; slope, 2.14% per year; 95% confidence interval [0.79%, 3.49%]). Ventral hernia repair had the largest growth in robotic procedures (1.51% to 13.94%; 9.23-fold change; slope, 2.86% per year; 95% confidence interval [1.04%, 4.68%]). Regions with the largest increase in robotic utilization were primarily along the Northeast, Midwest, and West Coast. CONCLUSIONS: Robot utilization in general surgery is increasing at different rates across the United States in the Veterans Health Administration. Future studies should investigate the regional disparities and drivers of this approach.

INTRODUCTION: The use of the robot in general surgery has exploded in the last decade. The Veterans Health Administration presents a unique opportunity to study differences between surgical approaches due to the ability to control for health system and insurance variability. This study compares clinical outcomes between robot-assisted and laparoscopic or open techniques for three general surgery procedures. METHODS: A retrospective observational study using the Veterans Affair Surgical Quality Improvement Program database. Operative time, length of stay, and complications were compared for cholecystectomy (robot-assisted versus laparoscopic), ventral, and inguinal hernia repair (robot-assisted versus laparoscopic or open) from 2015 to 2019. RESULTS: More than 80,000 cases were analyzed (21,652 cholecystectomy, 9214 ventral hernia repairs, and 51,324 inguinal hernia repairs). Median operative time was longer for all robot-assisted approaches as compared to laparoscopic or open techniques with the largest difference seen between open and robot-assisted primary ventral hernia repair (unadjusted difference of 93 min, P < 0.001). Median length of stay was between 1 and 4 d and significantly for robot-assisted ventral hernia repairs (versus open, P < 0.01; versus lap for recurrent hernia, P < 0.05). Specific postoperative outcomes of interest were overall low with few differences between techniques. CONCLUSIONS: While the robotic platform was associated with longer operative time, these findings must be interpreted in the context of a learning curve and indications for use (i.e., use of the robot for technically challenging cases). Our findings suggest that at the Veterans Health Administration, the robot is as safe a platform for common general surgery procedures as traditional approaches. Future studies should focus on patient-centered outcomes including pain and cosmesis.

BACKGROUND: This study investigated national implementation patterns and perioperative outcomes of minimally invasive gastrectomy (MIG) in gastric cancer surgery in the United States. METHODS: The National Inpatient Sample (NIS) was queried for patients who underwent elective gastrectomy for gastric cancer from 2008-2018. The MIG versus open gastrectomy approach was correlated with hospital factors, patient characteristics, and complications. RESULTS: There was more than a fivefold increase in MIG from 5.8% in 2008 to 32.9% in 2018 (nptrend < 0.001). Patients undergoing MIG had a lower Elixhauser Comorbidity Index (p = 0.001). On risk adjusted analysis, black patients (AOR = 0.77, p = 0.024) and patients with income below 25th percentile (AOR = 0.80, p = 0.018) were less likely to undergo MIG. When these analyses were limited to minimally invasive capable centers only, these differences were not observed. Hospitals in the upper tertile of gastrectomy case volume, Northeast, and urban teaching centers were more likely to perform MIG. Overall, MIG was associated with a 0.7-day decrease in length of stay, reduced risk adjusted mortality rates (AOR = 0.58, p = 0.05), and a $4,700 increase in total cost. CONCLUSIONS: In this national retrospective study, we observe socioeconomic differences in patients undergoing MIG, which is explained by hospital level factors in MIG utilization. We demonstrate that MIG is associated with a lower mortality compared with open gastrectomy. Establishing MIG as a safe approach to gastric cancers and understanding regional differences in implementation patterns can inform delivery of equitable high-quality health care.

BACKGROUND: Pathological treatment effect of resected pancreatic adenocarcinoma after neoadjuvant therapy has prognostic implications. The impact for patients who received chemotherapy alone or chemoradiotherapy is not well defined. METHODS: Patients with localized pancreatic adenocarcinoma who had pancreatectomy after neoadjuvant therapy at 3 centers from 2011 to 2017 were retrospectively analyzed. The chemotherapy and chemoradiotherapy groups were evaluated separately. RESULTS: Of 525 patients, 148 received neoadjuvant chemotherapy and 377 received chemoradiotherapy. The chemoradiotherapy group had a better treatment effect (score 0: 10%, score 1: 30%, score 2: 42%, and score 3: 18%) than the chemotherapy group (score 0: 2%, score 1: 8%, score 2: 35%, and score 3: 55%) (P < .001). Median overall survival was similar between the 2 groups (25.8 vs 26.4 months). Median overall survival for score 0/1, 2, or 3 was 72.2, 38.5, and 20.0 months in the chemotherapy group and 37.9, 24.5, and 19.0 months in the chemoradiotherapy group. Score 2 in the chemotherapy group was associated with better overall survival compared to score 3 (adjusted hazard ratio: 0.49, P = .005), whereas only combined score 0/1 reached significance over score 2 for the chemoradiotherapy group (hazard ratio: 0.63, P = .006). CONCLUSION: The prognostic significance of pathological treatment effect for localized pancreatic adenocarcinoma differs for patients receiving neoadjuvant chemotherapy or neoadjuvant chemoradiotherapy.

Importance: The utilization of robot-assisted minimally invasive esophagectomy (RAMIE) for esophageal cancer is increasing, despite limited data comparing RAMIE with other surgical approaches. Objective: To evaluate the literature for clinical outcomes of RAMIE compared with video-assisted minimally invasive esophagectomy (VAMIE) and open esophagectomy (OE). Data Sources: A systematic search of PubMed, Cochrane, Ovid Medline, and Embase databases from January 1, 2013, to May 6, 2020, was performed. Study Selection: Studies that compared RAMIE with VAMIE and/or OE for cancer were included. Data Extraction and Synthesis: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guideline, data were extracted by independent reviewers. A random-effects meta-analysis of 9 propensity-matched studies was performed for the RAMIE vs VAMIE comparison only. A narrative synthesis of RAMIE vs VAMIE and OE was performed. Main Outcomes and Measures: The outcomes of interest were intraoperative outcomes (ie, estimated blood loss [EBL], operative time, lymph node [LN] harvest), short-term outcomes (anastomotic leak, recurrent laryngeal nerve [RLN] palsy, pulmonary and total complications, and 90-day mortality), and long-term oncologic outcomes. Results: Overall, 21 studies (2 randomized clinical trials, 11 propensity-matched studies, and 8 unmatched studies) with 9355 patients were included. A meta-analysis was performed with 9 propensity-matched studies comparing RAMIE with VAMIE. The random-effects pooled estimate found an adjusted risk difference (RD) of -0.06 (95% CI, -0.11 to -0.01) favoring fewer pulmonary complications with RAMIE. There was no evidence of differences between RAMIE and VAMIE in LN harvest (mean difference [MD], -1.1 LN; 95% CI, -2.45 to 0.25 LNs), anastomotic leak (RD, 0.0; 95% CI, -0.03 to 0.03), EBL (MD, -6.25 mL; 95% CI, -18.26 to 5.77 mL), RLN palsy (RD, 0.01; 95% CI, -0.08 to 0.10), total complications (RD, 0.05; 95% CI, -0.01 to 0.11), or 90-day mortality (RD, -0.01; 95% CI, -0.02 to 0.0). There was low certainty of evidence that RAMIE was associated with a longer disease-free survival compared with VAMIE. For OE comparisons (data not pooled), RAMIE was associated with a longer operative time, decreased EBL, and less pulmonary and total complications. Conclusions and Relevance: In this study, RAMIE had similar outcomes as VAMIE but was associated with fewer pulmonary complications compared with VAMIE and OE. Studies on long-term functional and cancer outcomes are needed.

BACKGROUND: Robotic ventral hernia repair (VHR) has seen rapid adoption, but with limited data assessing clinical outcome or cost. This systematic review compared robotic VHR with laparoscopic and open approaches. METHODS: This systematic review was undertaken in accordance with PRISMA guidelines. PubMed, MEDLINE, Embase, and Cochrane databases were searched for articles with terms relating to 'robot-assisted', 'cost effectiveness', and 'ventral hernia' or 'incisional hernia' from 1 January 2010 to 10 November 2020. Intraoperative and postoperative outcomes, pain, recurrence, and cost data were extracted for narrative analysis. RESULTS: Of 25 studies that met the inclusion criteria, three were RCTs and 22 observational studies. Robotic VHR was associated with a longer duration of operation than open and laparoscopic repairs, but with fewer transfusions, shorter hospital stay, and lower complication rates than open repair. Robotic VHR was more expensive than laparoscopic repair, but not significantly different from open surgery in terms of cost. There were no significant differences in rates of intraoperative complication, conversion to open surgery, surgical-site infection, readmission, mortality, pain, or recurrence between the three approaches. CONCLUSION: Robotic VHR was associated with a longer duration of operation, fewer transfusions, a shorter hospital stay, and fewer complications compared with open surgery. Robotic VHR had higher costs and a longer operating time than laparoscopic repair. Randomized or matched data with standardized reporting, long-term outcomes, and cost-effectiveness analyses are still required to weigh the clinical benefits against the cost of robotic VHR.

BACKGROUND: Rapid adoption of robotic-assisted general surgery procedures, particularly for cholecystectomy, continues while questions remain about its benefits and utility. The objective of this study was to compare the clinical effectiveness of robot-assisted cholecystectomy for benign gallbladder disease as compared with the laparoscopic approach. METHODS: A literature search was performed from January 2010 to March 2020, and a narrative analysis was performed as studies were heterogeneous. RESULTS: Of 887 articles screened, 44 met the inclusion criteria (range 20-735,537 patients). Four were randomized controlled trials, and four used propensity-matching. There were variable comparisons between operative techniques with only 19 out of 44 studies comparing techniques using the same number of ports. Operating room time was longer for the robot-assisted technique in the majority of studies (range 11-55 min for 22 studies, p < 0.05; 15 studies showed no difference; two studies showed shorter laparoscopic times), while conversion rates and intraoperative complications were not different. No differences were detected for the length of stay, surgical site infection, or readmissions. Across studies comparing single-port robot-assisted to multi-port laparoscopic cholecystectomy, there was a higher rate of incisional hernia; however, no differences were noted when comparing single-port robot-assisted to single-port laparoscopic cholecystectomy. CONCLUSIONS: Clinical outcomes were similar for benign, elective gallbladder disease for robot-assisted compared with laparoscopic cholecystectomy. Overall, the rates of complications were low. More high-quality studies are needed as the robot-assisted technique expands to more complex gallbladder disease, where its utility may prove increasingly beneficial.

IMPORTANCE: In the United States, acute pancreatitis is one of the leading causes of hospital admission from gastrointestinal diseases, with approximately 300â¯000 emergency department visits each year. Outcomes from acute pancreatitis are influenced by risk stratification, fluid and nutritional management, and follow-up care and risk-reduction strategies, which are the subject of this review. OBSERVATIONS: MEDLINE was searched via PubMed as was the Cochrane databases for English-language studies published between January 2009 and August 2020 for current recommendations for predictive scoring tools, fluid management and nutrition, and follow-up and risk-reduction strategies for acute pancreatitis. Several scoring systems, such as the Bedside Index of Severity in Acute Pancreatitis (BISAP) and the Acute Physiology and Chronic Health Evaluation (APACHE) II tools, have good predictive capabilities for disease severity (mild, moderately severe, and severe per the revised Atlanta classification) and mortality, but no one tool works well for all forms of acute pancreatitis. Early and aggressive fluid resuscitation and early enteral nutrition are associated with lower rates of mortality and infectious complications, yet the optimal type and rate of fluid resuscitation have yet to be determined. The underlying etiology of acute pancreatitis should be sought in all patients, and risk-reduction strategies, such as cholecystectomy and alcohol cessation counseling, should be used during and after hospitalization for acute pancreatitis. CONCLUSIONS AND RELEVANCE: Acute pancreatitis is a complex disease that varies in severity and course. Prompt diagnosis and stratification of severity influence proper management. Scoring systems are useful adjuncts but should not supersede clinical judgment. Fluid management and nutrition are very important aspects of care for acute pancreatitis.

BACKGROUND AND OBJECTIVES: This study investigated the influence of the transcription factor SMAD4 on overall patient survival following surgical resection of pancreatic ductal adenocarcinoma (PDAC). METHODS: The SMAD4 status of 125 surgically resected PDAC specimens at a large academic center from 2014 to 2017 was routinely determined prospectively and correlated with clinicopathologic characteristics and overall survival. RESULTS: SMAD4 loss was identified in 62% of patients and was not associated with overall survival (OS). On multivariate Cox proportional hazards survival analysis, histologic grade was the best predictor of survival in the SMAD4(-) population (adjusted hazard ratio = 4.8, p < .0001). In the SMAD4(+) population, histologic grade was not associated with survival on multivariate analysis. In the SMAD4(-) population, median OS for well/moderately differentiated patients and poorly differentiated patients was 39.6 and 8.6 months, respectively. CONCLUSION: In this large cohort of resected PDAC, routine SMAD4 assessment identified a subpopulation of patients with SMAD4(-) and histologically poorly differentiated tumors that had significantly poor prognosis with median OS of 8.6 months. Characterization of the role of SMAD4 within the context of poorly differentiated tumors may help settle the controversy regarding SMAD4 in PDAC and lead to identification of personalized therapeutic strategies for subgroups of PDAC.

Acute limb ischemia (ALI) related to pheochromocytoma is rare. We describe a 69-year-old woman who presented with ALI due to a thromboembolic phenomenon from new-onset atrial fibrillation that was successfully treated with intra-arterial catheter-directed lysis and systemic anticoagulation. Further workup revealed a left adrenal mass and biochemical test results consistent with pheochromocytoma. The patient underwent a retroperitoneoscopic converted to open left adrenalectomy, splenectomy, and distal pancreatectomy because of severe inflammation in the retroperitoneum, probably from an adrenal or subcapsular renal hematoma secondary to systemic anticoagulation. Interval imaging before adrenalectomy for pheochromocytoma should be considered after thrombolysis and anticoagulation for ALI.
RESUMO
Pancreatic cysts include a variety of benign, premalignant, and malignant lesions. Endometrial cysts in the pancreas are exceedingly rare lesions that are difficult to diagnose pre-operatively. This report describes the findings in a 43-year-old patient with a recent episode of acute pancreatitis who presented with a large cyst in the tail of the pancreas. Imaging demonstrated a loculated pancreatic cyst, and cyst fluid aspiration revealed an elevated amylase and carcinoembryonic antigen. The patient experienced an interval worsening of abdominal pain, fatigue, diarrhea, and a 15-pound weight loss 3 mo after the initial episode of pancreatitis. With concern for a possible pre-malignant lesion, the patient underwent a laparoscopic distal pancreatectomy with splenectomy, which revealed a 16 cm × 12 cm × 4 cm lesion. Final histopathology was consistent with an intra-pancreatic endometrial cyst. Here we discuss the overlapping imaging and laboratory features of pancreatic endometrial cysts and mucinous cystic neoplasms of the pancreas.

Low serum testosterone has been associated with obesity, type 2 diabetes, metabolic syndrome, and atherosclerosis. Individuals with these comorbidities are at increased risk of premature death and other adverse health effects. Clinical data portend low testosterone as a risk factor for developing these conditions which are supported by the hypogonadal-obesity-adipocytokine hypothesis. The authors support comprehensive evaluation for these comorbid conditions in men found to have low serum testosterone.
