Consequences of anastomotic leaks after minimally invasive esophagectomy: A single-center experience.

Background: Anastomotic leak (AL) after minimally invasive esophagectomy (MIE) is a well-described source of morbidity for patients undergoing surgical treatment of esophageal neoplasm. With improved early recognition and endoscopic management techniques, the long-term impact remains unclear. Methods: A retrospective review was conducted of patients who underwent MIE for esophageal neoplasm between January 2015 and June 2021 at a single institution. Cohorts were stratified by development of AL and subsequent management. Baseline demographics, perioperative data, and post-operative outcomes were examined. Results: During this period, 172 MIEs were performed, with 35 of 172 (20.3%) complicated by an AL. Perioperative factors independently associated with AL were post-operative blood transfusion (leak rate 52.9% versus 16.8%; p = 0.0017), incompleteness of anastomotic rings (75.0% vs 19.1%; p = 0.027), and receiving neoadjuvant therapy (18.5% vs 30.8%; p < 0.0001). Inferior short-term outcomes associated with AL included number of esophageal dilations in the first post-operative year (1.40 vs 0.46, p = 0.0397), discharge disposition to a location other than home (22.9% vs 8.8%, p = 0.012), length of hospital stay (17.7 days vs 9.6 days; p = 0.002), and time until jejunostomy tube removal (134 days vs 79 days; p = 0.0023). There was no significant difference in overall survival between patients with or without an AL at 1 year (79% vs 83%) or 5 years (50% vs 47%) (overall log rank p = 0.758). Conclusions: In this large single-center series of MIEs, AL was associated with inferior short-term outcomes including hospital length of stay, discharge disposition other than to home, and need for additional endoscopic procedures, without an accompanying impact on 1-year or 5-year survival. Key message: In this large, single-center series of minimally invasive esophagectomies, anastomotic leak was associated with worse short-term outcomes including hospital length of stay, discharge disposition other than to home, and need for additional endoscopic procedures, but was not associated with worse long-term survival. The significant association between neoadjuvant therapy and decreased leak rates is difficult to interpret, given the potential for confounding factors, thus careful attention to modifiable pre- and peri-operative patient factors associated with anastomotic leak is warranted.

Aortic arch replacement and autologous pericardial tracheal patch for an aorto-tracheal fistula.

Aorto-tracheal fistulas are rare and highly lethal, with few reports of successful surgical intervention. We present a 48-year-old man with an aorto-tracheal fistula induced by radiation therapy for tracheal squamous cell carcinoma. He presented with hemoptysis and chest pain and workup revealed the aorta-tracheal fistula between the posterior aortic arch and anterior distal trachea. He was emergently taken to surgery. To our knowledge, this is the first report of an aorto-tracheal fistula successfully treated with a transverse aortic arch replacement and complex tracheal repair using autologous pericardium with an omental buttress.

Formal robotic training diminishes the learning curve for robotic pancreatoduodenectomy: Implications for new programs in complex robotic surgery.

INTRODUCTION: The learning curve associated with robotic pancreatoduodenectomy (RPD) is a hurdle for new programs to achieve optimal results. Since early analysis, robotic training has recently expanded, and the RPD approach has been refined. The purpose of this study is to examine RPD outcomes for surgeons who implemented a new program after receiving formal RPD training to determine if such training reduces the learning curve. METHODS: Outcomes for consecutive patients undergoing RPD at a single tertiary institution were compared to optimal RPD benchmarks from a previously reported learning curve analysis. Two surgical oncologists with formal RPD training performed all operations with one surgeon as bedside assistant and the other at the console. RESULTS: Forty consecutive RPD operations were evaluated. Mean operative time was 354 ± 54 min, and blood loss was 300 ml. Length of stay was 7 days. Three patients (7.5%) underwent conversion to open. Pancreatic fistula affected five patients (12.5%). Operative time was stable over the study and lower than the reported benchmark. These RPD operative outcomes were similar to reported surgeon outcomes after the learning curve. CONCLUSION: This study suggests formal robotic training facilitates safe and efficient adoption of RPD for new programs, reducing or eliminating the learning curve.

Optimal Resources for Rural Surgery.

BACKGROUND: Timely access to emergency general surgery services, including trauma, is a critical aspect of patient care. This study looks to identify resource availability at small rural hospitals in order to improve the quality of surgical care. METHODS: Forty-five nonteaching hospitals in West Virginia were divided into large community hospitals with multiple specialties (LCHs), small community hospitals with fewer specialties (SCHs), and critical access hospitals (CAHs). A 58-question survey on optimal resources for surgery was completed by 1 representative surgeon at each hospital. There were 8 LCHs, 18 SCHs, and 19 CAHs with survey response rates of 100%, 83%, and 89%, respectively. RESULTS: One hundred percent of hospitals surveyed had respiratory therapy and ventilator support, computerized tomography (CT) scanner and ultrasound, certified operating rooms, lab support, packed red blood cells (PRBC), and FFP accessible 24/7. Availability of cryoprecipitate, platelets, tranexamic acid (TXA), and prothrombin complex concentrate (PCC) decreased from LCHs to CAHs. The majority had board-certified general surgeons; however, only 86% LCHs, 53% SCHs, and 50% CAHs had advanced trauma life support (ATLS) certification. One hundred percent of LCHs had operating room (OR) crew on call within 30 minutes, emergency cardiovascular equipment, critical care nursing, on-site pathologist, and biologic/synthetic mesh, whereas fewer SCHs and CAHs had these resources. One hundred percent of LCHs and SCHs had anesthesia availability 24/7 compared to 78% of CAHs. DISCUSSION: Improving access to the aforementioned resources is of utmost importance to patient outcomes. This will enhance rural surgical care and decrease emergency surgical transfers. Further education and research are necessary to support and improve rural trauma systems.

Intraoperative Radiation Therapy Versus Whole Breast Radiation for Early-Stage Breast Cancer Treatment in Rural Appalachia.

BACKGROUND: Intraoperative radiation therapy (IORT) is an alternate accelerated form of radiation following breast-conserving surgery (BCS). Lack of data regarding long-term outcomes has limited adoption. We report our experience with IORT in patients undergoing BCS versus whole breast radiation therapy (WBRT). METHODS: Retrospective review of patients undergoing BCS with IORT versus WBRT (2012-2017). Inclusion: low grade, T1-2N0M0, estrogen receptor/progesterone receptor positive, and Her2-negative infiltrating ductal carcinomas. IORT was delivered as a single fraction of radiation (20 Gy) intraoperatively. Outcomes were compared using Fisher's test for discrete variables or Wilcoxon signed-rank test for continuous variables. Kaplan-Meier method was used to estimate disease-free survival (DFS). RESULTS: Fifty-one patients (44%) received IORT, and 66 (56%) received WBRT. There was no difference in age, tumor size, receptor status, or in-breast recurrence (1.9% vs 0%, all P > .05). Length of follow-up was longer in the WBRT group due to time to inception of IORT (mean ± SD: 44 ± 8.1 vs 73 ± 13 months, P < .001). There was no difference in DFS between the 2 groups (HR 2.5; P = .44). IORT patients experienced delay to BCS (mean ± SD: 38 ± 12.7 vs 27 ± 12.2 days, P < .001) likely due to coordination of care. Analysis demonstrated IORT patients would have traveled a mean distance of 20 miles to the closest WBRT center (range 1-70, miles) for a mean travel time of 31 minutes (range 4-90, minutes) per WBRT treatment. DISCUSSION: IORT produces noninferior oncologic outcomes and decreased skin toxicity compared with WBRT. It can be convenient for patients in rural regions with limited health care access.

Contemporary look at extracorporeal membrane oxygenation as a bridge to reoperative lung transplantation in the United States - a retrospective study.

The purpose of this study was to examine the influence of extracorporeal membrane oxygenation (ECMO) as a bridge to reoperative lung transplantation (LT) on outcomes and survival. A total of 1960 LT recipients transplanted a second time between 2005 and 2017 were analyzed using the United Network for Organ Sharing (UNOS) Organ Procurement and Transplantation Network (OPTN). Of these recipients, 99 needed ECMO as a bridge to reoperative LT. Mean age was 50 ± 14 years, 47% were females, and the group with ECMO was younger [42 (30-59) vs. 55 (40-62) years]. In both univariate and multivariable analyses (adjusting for age and gender), the ECMO group had greater incidence of prolonged ventilation >48 h (83% vs. 40%, P < 0.001) and in-hospital dialysis (27% vs. 7%, P < 0.001). There were no differences in incidence of acute rejection (15% vs. 11%, P = 0.205), airway dehiscence (4% vs. 2%, P = 0.083), stroke (3% vs. 2%, P = 0.731), or reintubation (20% vs. 20%, P = 0.998). Kaplan-Meier survival analysis showed the ECMO group had reduced 1-year survival (66.6% vs. 83.0%, P < 0.001). After covariate adjustment, the ECMO group only had increased risk for 1-year mortality in the 2005-2011 era (HR = 2.57, 95% CI = 1.45-4.57, P = 0.001). For patients who require reoperative LT, bridging with ECMO was historically a significant predictor of poor outcome, but may be improving in recent years.

Enhancing the Educational Value and Faculty Attendance of a Morbidity and Mortality Conference.

OBJECTIVE: There exists significant variation in the approach to and execution of morbidity and mortality conference (M&MC). Faculty attendance remains a working challenge. We sought to change our department's M&MC and hypothesized improved educational value and attendance. DESIGN: Complications were submitted in Clavien-Dindo format. A designated M&MC moderator facilitated discussion. A teaching point (TP) was assigned to each complication intended to be the focus of discussion. Presentations followed a structured 6-slide PowerPoint template. A web-based tool using Google Forms was developed and distributed as an "App" for tracking of attendance. An anonymous online survey was distributed to participants to elucidate perception of M&MC following the intervention. SETTING: Academic medical center. PARTICIPANTS: Postgraduate year-1 to 5 surgery residents and faculty at West Virginia University, Morgantown. RESULTS: Forty-eight of sixty-three surveys were returned (response rate 76%). Twenty-five faculty (70%) and 23 residents (82%) responded. A predetermined TP was viewed as the most favorable change made by both faculty and residents. 65% of faculty and residents acknowledged improved educational value, 58% found a single moderator to help streamline Morbidity and Mortality (M&M) presentations and 71% felt that a standard PowerPoint template improved quality of presentations. Both residents (96%) and faculty (68%) believed a predetermined TP improved the educational value of the conference and medical knowledge during preparation. More residents (43%) than faculty (16%) believed that changes to the department's M&MC format allowed better identification of quality improvement issues. Furthermore, the majority of residents (83%) believed that changes to the department's M&M format allowed better identification of system factors compared to faculty (32%), p = 0.003. Faculty participation increased from 60% to 80% after changes (p = 0.03). CONCLUSIONS: The educational value of M&MC and attendance can be improved with simple changes, but faculty and residents may have different expectations and perceptions.

A review of general surgery resident experience in common bile duct exploration in the ERCP era.

BACKGROUND: Use of minimally invasive techniques for management of common bile duct (CBD) stones has led to declining number of CBD explorations (CBDE) performed at teaching and non-teaching institutions. We evaluate the impact of this decline on surgery training in bile duct procedures. STUDY DESIGN: National operative data for general surgery residents (GSR) were examined from 2000 to 2018. Biliary operations including, cholecystectomy open and laparoscopic, and CBDE open and laparoscopic were evaluated for mean number of cases per graduating GSR. RESULTS: Despite increases in number of GSR, case numbers for laparoscopic cholecystectomy increased 39% from 84 to 117, p < .00001, per GSR. Mean number of cases for open CBDE, however, decreased 74% from 2.7 to 0.7, p < .00001, per GSR and laparoscopic CBDE declined 22% from 0.9 to 0.7 per resident. CONCLUSION: GSR operative case volume in CBDE has declined significantly creating a training deficiency for this complex skill. Novel simulation, including fresh cadavers, may offer the best option with high-fidelity, dynamic training to mitigate the loss of low volume, high acuity procedures.

Extracorporeal Membrane Oxygenation in the Perioperative Care of the Lung Transplant Patient.

Lung transplantation (LT) is definitive therapy for end-stage lung disease. Donor allocation based on medical urgency has led to an increased trend in the transplantation of sicker and older patients. Mechanical ventilation (MV) formerly was the only method of bridging high-acuity patients to LT. When the physiological demands of ventilatory support exceeds the capability of MV, extracorporeal membrane oxygenation (ECMO) may become necessary. Recent improvements in ECMO technology and component design have led to a resurgence of interest in its use before, during, and after LT. Survival with ECMO as a bridge to LT has improved over time, now with many centers reporting little or no difference in outcomes, and some even reporting better outcomes, as compared with MV. Extracorporeal life support may also be used intraoperatively. In many studies to date, ECMO or cardiopulmonary bypass (CPB) has been reserved for patients who became hemodynamically unstable during the procedure or patients who could not tolerate single-lung ventilation. Both methods of support are fraught with potential complications. However, multiple studies comparing ECMO with CPB have shown that intraoperative use of ECMO resulted in improved outcomes and overall survival as well as lower rates of bleeding complications. In order to further reduce complications associated with ECMO, planned intraoperative ECMO use is occasionally reserved for high-risk patients who might otherwise require CPB. Future studies will need to improve patient selection to fully take advantage of the use of ECMO in LT while minimizing its costs.

Ethnic and racial disparities of pancreatic adenocarcinoma in Florida.

BACKGROUND: Racial disparities are known to negatively impact survival in patients with pancreatic adenocarcinoma. However, data regarding the Hispanic ethnicity are scarce in the pancreatic cancer literature. Therefore, the aim of this study is to analyze whether race and ethnicity are independent predictors of survival in patients with pancreatic adenocarcinoma in Florida. METHODS: A retrospective study was performed utilizing all patients diagnosed with pancreatic adenocarcinoma between 1983 and 2013 in the Florida Cancer Data System (FCDS). Statistical analysis was performed using Cox proportional hazard regression models, and Kaplan-Meier survival analysis. RESULTS: Of 36,756 patients identified with pancreatic adenocarcinoma in the FCDS, 9.1% were Hispanic and 91% were non-Hispanic. Ethnicity was associated with improved survival among Hispanics compared to non-Hispanics (HR 0.86, 95% CI 0.82-0.90, both p = 0.001). Furthermore, 90% of patients were White, and 9% were Black. Compared to Whites, Blacks had a significantly decreased survival (HR 1.07, 95% CI 1.03-1.13, p = 0.003). CONCLUSION: In Florida patients with pancreatic adenocarcinoma, Hispanic ethnicity is associated with improved survival compared to Non-Hispanics. Additionally, Blacks present at an earlier age and later stage of diagnosis with worse survival compared to Whites and Others.

Laparoscopic Removal of Angelchik Prosthesis Followed by Interval Sleeve Gastrectomy.

INTRODUCTION: The Angelchik prosthesis (AP) is a historic antireflux device which consists of a C-shaped silicone ring placed around the gastroesophageal junction (GEJ) and secured by Dacron tape. We present a rare experience with an AP and its impact on bariatric surgical outcomes. CASE: Our patient is a 66-year-old woman who had an open antireflux procedure with an AP in 1987. She presented to a bariatric clinic for consideration of bariatric surgery for the treatment of morbid obesity and associated comorbidities. She also reported significant problems with reflux and dysphagia. After an appropriate work-up, an AP was identified at her GEJ. She was taken to the operating room for laparoscopic removal with planned interval laparoscopic sleeve gastrectomy. Intraoperatively, the AP was identified around the GEJ; after extensive adhesiolysis, the prosthesis was removed. Postoperatively, in order to determine if the AP had caused any lasting esophageal motility problems, the patient underwent a high-resolution esophageal manometry which demonstrated normal esophageal motility. Interval laparoscopic sleeve gastrectomy was performed safely 9 weeks later. CONCLUSION: Although rarely used, it is still possible to encounter an Angelchik prosthesis in practice. General and bariatric surgeons need to be aware of this rare device and understand how to manage its related complications.

Lung transplantation and Affordable Care Act Medicaid expansion in the era of lung allocation score - a retrospective study.

This study evaluated the impact of Medicaid eligibility expansion (ME) on lung transplant (LT) listings and Medicaid coverage. Data on LT candidates aged 18-64 were obtained from the Scientific Registry of Transplant Recipients (N = 9153). The impact of ME was evaluated by comparing LT listings in 2011-2013 with listings in 2014-2016, as well as comparing states that had and had not adopted ME in 2014. LT listings increased by 7.7% nationally post-ME. In ME states, LT listings increased by 15.2%, whereas nonexpansion states decreased by 1.5%. LT candidates with Medicaid increased after ME nationally (8.3% vs. 9.9%, P = 0.006) and in ME states (9.7% vs. 11.5%, P = 0.036), but not in nonexpansion states (6.6% vs. 7.7%, P = 0.170). Following multivariable adjustment, LT listings in ME states had 58% greater odds for Medicaid compared to nonexpansion states (P < 0.001). Expansion of Medicaid provided greater healthcare access and increased LT listings, but only within states that adopted eligibility expansion.

Robotic Versus Video-Assisted Thoracoscopic Surgery Pulmonary Segmentectomy: A Cost Analysis.

OBJECTIVE: Pulmonary segmentectomy using robotic assistance is often perceived as being more expensive than segmentectomy using video-assisted thoracic surgery. The robotic technique allows for meticulous dissection during segmentectomy, potentially leading to fewer parenchymal injuries, fewer air leaks, and shorter length of stay. This study compared pulmonary segmentectomy costs using video-assisted thoracic surgery versus robotic with manual staplers versus robotic with robotic staplers. METHODS: Retrospective analyses were performed evaluating our early experience with robotic pulmonary segmentectomy for 30 months compared with the video-assisted thoracic surgery approach. All 50 anatomical segmentectomies performed since introduction of robotic technique in the practice were included. Twenty-eight procedures were robotic-assisted and 22 were video-assisted thoracic surgery. Procedure-specific evaluation of direct costs was performed, including cost of robotic instruments, staplers, and average length of stay in the hospital. RESULTS: The mean ± SD age was 70 ± 10 years (range = 43-91 years). There were 12 males in the robotic group and eight in the video-assisted thoracic surgery group (P = 0.642). The mean age was 69 years in the robotic group and 71 years in the video-assisted thoracic surgery group (P = 0.367). The median length of stay was 2 (2-4) days in the robotic group (range = 1-9) and 4 (2-5) days in the video-assisted thoracic surgery group (range = 1-20, P = 0.089). The cost of robotic segmentectomy with manual staplers was less than that with robotic staplers. Both robotic techniques cost less than video-assisted thoracic surgery. CONCLUSIONS: In this small series, cost and outcomes in our early experience with robotic-assisted segmentectomy were comparable with our video-assisted thoracic surgery approach with trends toward shorter length of stay and fewer complications. Larger series are needed to validate these results.

Thoracic stent graft placement for repair of iatrogenic aortic injury secondary to sheath placement during pacemaker insertion.

We describe the inadvertent cannulation of the proximal descending thoracic aortic stent with a five French sheath during attempted pacemaker placement in an 88- year-old male. The injury was managed successfully by the percutaneous placement of a thoracic aortic stent graft with good outcome. Our case highlights the feasibility of managing this uncommon injury with this technique.
