Impact of automated alerts on discharge opioid overprescribing after general surgery.

DISCLAIMER: In an effort to expedite the publication of articles, AJHP is posting manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time. PURPOSE: The objectives of this study were to identify the most performed surgical procedures associated with the highest rates of discharge opioid overprescribing and to implement an electronic health record (EHR) alert to reduce discharge opioid overprescribing. METHODS: This quality improvement, before-and-after study included patients undergoing one of the identified target procedures-laparoscopic cholecystectomy, unilateral open inguinal hernia repair, and laparoscopic appendectomy-at an academic medical center. The alert notified providers when the prescribed opioid quantity exceeded guideline recommendations. The preimplementation cohort included surgical encounters from January 2020 to December 2021. The EHR alert was implemented in May 2022 following provider education via email and in-person presentations. The postimplementation cohort included surgical encounters from May to August 2022. The primary outcome was the proportion of patients with a discharge opioid supply exceeding guideline recommendations (overprescribing). RESULTS: A total of 1,478 patients were included in the preimplementation cohort, and 141 patients were included in the postimplementation cohort. The rate of discharge opioid overprescribing decreased from 48% in the preimplementation cohort to 3% in the postimplementation cohort, with an unadjusted absolute reduction of 45% (95% confidence interval, 41% to 49%; P < 0.001) and an adjusted odds ratio of 0.03 (95% confidence interval, 0.01 to 0.08; P < 0.001). Among patients who received opioids, the mean (SD) opioid supply at discharge decreased from 92 (43) oral morphine milligram equivalents (MME) (before implementation) to 57 (20) MME (after implementation) (P < 0.001). The proportion of patients who received additional opioid prescriptions within 1 to 14 days of hospital discharge did not change (P = 0.76). CONCLUSION: Implementation of an EHR alert along with provider education can reduce discharge opioid overprescribing following general surgery.

Enhanced recovery after surgery may mitigate the risks associated with robotic-assisted fundoplication in lung transplant patients.

INTRODUCTION: A history of lung transplantation is a risk factor for poor outcomes in patients undergoing laparoscopic fundoplication. We wanted to determine whether enhanced recovery after a robotic-assisted surgery program would mitigate these risks. METHODS: We performed a single-center retrospective analysis of the Society of Thoracic Surgery database for patients who underwent elective antireflux procedures from 1/2018 to 2/2021 under the enhanced recovery after surgery program using robotic assistance. We identified the patient and surgical characteristics, morbidity, length of stay, and 30-day readmission rates. RESULTS: Among 386 patients who underwent barrier creation, 41 had previously undergone a lung transplant, either bilateral (n = 28) or single (n = 13). There were no significant differences in postoperative complications (9.8% vs. 5.2%, p = 0.27), median hospital length of stay (1 d vs. 1 d, p = 0.28), or 30-day readmission (7.3% vs. 4.9%, p = 0.46). Bivariate analysis showed that older age (p = 0.03), history of DVT/PE (p < 0.001), history of cerebrovascular events (p = 0.03), opioid dependence (p = 0.02), neurocognitive dysfunction (p < 0.001), and dependent functional status (p = 0.02) were associated with postoperative complications. However, lung transplantation was not associated with an increased risk of postoperative complications (p = 0.28). DISCUSSION: The risk of surgical complications in patients with a history of lung transplantation may be mitigated by the combination of ERAS and minimally invasive surgery such as robot-assisted surgery.

Long Interspersed Nuclear Element-1 Analytes in Extracellular Vesicles as Tools for Molecular Diagnostics of Non-Small Cell Lung Cancer.

Aberrant expression of the oncogenic retrotransposon LINE-1 is a hallmark of various cancer types, including non-small cell lung cancers (NSCLCs). Here, we present proof-of-principle evidence that LINE-1 analytes in extracellular vesicles (EVs) serve as tools for molecular diagnostics of NSCLC, with LINE-1 status in tumor cells and tissues mirroring the LINE-1 mRNA and ORF1p cargos of EVs from lung cancer cell culture conditioned media or human plasma. The levels of LINE-1 analytes in plasma EVs from ostensibly healthy individuals were higher in females than males. While the profiles of LINE-1 mRNA and ORF1p in African Americans compared to Hispanics were not significantly different, African Americans showed slightly higher ORF1p content, and 2-3 times greater ranges of LINE-1 values compared to Hispanics. Whole plasma ORF1p levels correlated with EV ORF1p levels, indicating that most of the circulating LINE-1 protein is contained within EVs. EV LINE-1 mRNA levels were elevated in patients with advanced cancer stages and in select patients with squamous cell carcinoma and metastatic tumors compared to adenocarcinomas. The observed EV LINE-1 mRNA profiles paralleled the patterns of ORF1p expression in NSCLC tissue sections suggesting that LINE-1 analytes in plasma EVs may serve to monitor the activity of LINE-1 retroelements in lung cancer.

A systematic review of general surgery robotic training curriculums.

Background: As of the most recent surveys of resident programs in 2018, only slightly more than half of programs have formal robotic training curriculums implemented. Fewer programs have further assessed their own curriculum and its benefit. Method: We conducted a PubMed/MEDLINE literature search for robotic surgery curriculums and those that had assessment of their programs. Results: A total of 11 studies were reviewed. When reviewed in chronological order, there has been a progression towards more robotic specific objective data analysis as opposed to subjective surveying. There is a wide variation in curriculums, but simulation use is pervasive. Conclusions: Our review makes evident two important concepts-there is great variety in training curriculums and there is great benefit in implementation. The importance is in establishment of what makes resident training effective and supports the adaptable and successful surgeon. This may come from an adaptable curriculum but a structured test-out assessment.

Diversity of the free helical rim flap: A case series tailoring the microsurgical technique to esthetically optimize full-thickness nasal defect reconstructions.

INTRODUCTION: The free helical rim (FHR) flap offers like-with-like reconstruction for full-thickness nasal defects. A case series of nasal reconstruction using an FHR flap was presented, detailing surgical steps and refinements, as well as functional and esthetic outcomes. METHODS AND MATERIALS: This is a retrospective cohort study of composite nasal defect reconstruction with FHR flap from August 2018 to March 2020. Descriptive data were analyzed by SPSS software. RESULTS: Six cases were recruited, four were unilateral alar defects, one was hemi-nose, and one was ala plus tip. The average size of the defect was 2.5 × 2.8 cm2. Three FHR flaps were designed with retrograde pedicles and three with anterograde pedicles. The facial artery and veins were the recipient vessels in all cases. Vascular grafts were used in all six cases. Descending branch of the lateral circumflex femoral (DLCxF) artery and vein functioned as interposition vascular conduits in five cases. Superficial forearm vein grafts were used in one case. One patient needed flap re-exploration due to venous congestion. One patient had partial flap necrosis due to delayed infection, and one developed delayed wound dehiscence in the irradiated wound. The average follow-up was 18 months. CONCLUSION: The FHR flap has consistent vascular anatomy. It can be raised as an anterograde or retrograde flap for a contralateral or ipsilateral inset. FHR flap can be used in extensive composite nasal defects. This case series demonstrates that interposition vascular grafts are invariably needed and the possibility of using forearm vessels as grafts instead of DLCxF artery and vein.

Gastroesophageal Reflux Disease in 2023: When to Operate and Current Endoscopic Options for Antireflux Therapy.

Gastroesophageal reflux disease (GERD) is among the most prevalent diseases in the United States. Mainstay therapy is lifestyle modification and medical therapy. If patients have GERD despite medical therapy, appropriate testing should be performed to determine if surgical or endoscopic therapy will provide improvement in their symptoms. Gold standard therapy is a minimally invasive fundoplication. Patients with body mass index <35, small or no hiatal hernia, normal motility, and pathologic GERD should consider magnetic sphincter augmentation. If a patient is not interested in either fundoplication or MSA, they should consider endoscopic treatment with either STRETTA or Transoral Incisionless fundoplication 2.0. A meta-analysis by Gong and colleagues showed that endoscopic treatments are better compared with medical therapy but are worse than surgical therapy.

Surgical Treatment of Atrioesophageal Fistula: A Systematic Review.

BACKGROUND: Atrioesophageal fistula is a rare and morbid complication of ablation therapy for atrial fibrillation. Surgery provides increased survival; however, which surgical approach provides the best outcome is unclear. METHODS: We performed a retrospective analysis of cases in the literature and at our institution. We characterized patients by presenting symptoms, diagnostic method, surgical therapy with different approaches, and survival. RESULTS: In total, 219 patients were found, with 216 patients identified from 122 papers in the literature and 3 patients from our institutional database (2000-2022). The most common presenting symptoms included fever/chill (71.8%) and neurologic deficiency (62.9%). The overall survival for this cohort was 47%. Patients who had an operation had significantly improved survival compared with those who did not have an operation (71.9.3% vs 11%, P < .001). Patients who survived after surgical intervention typically underwent right thoracotomy (45.1%), patch repair of the left atrium (61.1%), and primary repair of the esophagus (68.3%) on cardiopulmonary bypass (84.8%) with a flap between the 2 organs (84.6%). Patients who had cardiopulmonary bypass had increased survival (39 of 45 [86.7%]) compared with those who did not have cardiopulmonary bypass (7 of 17 [41.2%], P < .001). CONCLUSIONS: Patients with atrioesophageal fistula should undergo surgical intervention. A patch repair of the left atrium and primary repair of the esophagus with a flap between the organs during cardiopulmonary bypass is the most common successful repair. Cardiopulmonary bypass may allow better débridement and repair of the left atrium, which may provide a survival advantage in the treatment of this rare disease.

Impact of the Southern Thoracic Surgical Association James W. Brooks Scholarship.

BACKGROUND: Medical students and general surgery residents often do not get exposure to cardiothoracic surgery (CTS) because of a decreased emphasis on CTS rotations during their training. The Southern Thoracic Surgical Association (STSA) began offering the Brooks Scholarship to medical students in 2010 and general surgery residents in 2014 to promote CTS. This study examines the impact of the scholarship. METHODS: We examined the history of the award and how STSA administers the award. Next we examined the impact of the award by evaluating the number of medical students and residents who are tracked to complete a CTS program. Finally we performed an analysis of the academic output of the awardees who have completed or were tracked to complete a CTS program. RESULTS: The scholarship was developed to honor the memory of past STSA President Dr James W. Brooks. The award is administered through the STSA scholarship committee and provides medical students and residents funds to attend the STSA annual meeting and the opportunity to spend time with a mentor during the meeting. Eighty-eight percent of medical student recipients (21/24) and 100% of general surgery resident recipients (15/15) have completed or are on track to complete a CTS program. The 36 recipients going into CTS have published a total of 823 papers and 9240 articles have cited those papers. CONCLUSIONS: The STSA medical student and general surgery Brooks scholarship awards were associated with completing or pursuing a career in CTS. STSA should continue the Brooks scholarship to attract talented medical students and residents to CTS.

Integrative metabolomics and transcriptomics analysis reveals novel therapeutic vulnerabilities in lung cancer.

BACKGROUND: Non-small cell lung cancer (NSCLC) comprises the majority (~85%) of all lung tumors, with lung adenocarcinoma (LUAD) and squamous cell carcinoma (LUSC) being the most frequently diagnosed histological subtypes. Multi-modal omics profiling has been carried out in NSCLC, but no studies have yet reported a unique metabolite-related gene signature and altered metabolic pathways associated with LUAD and LUSC. METHODS: We integrated transcriptomics and metabolomics to analyze 30 human lung tumors and adjacent noncancerous tissues. Differential co-expression was used to identify modules of metabolites that were altered between normal and tumor. RESULTS: We identified unique metabolite-related gene signatures specific for LUAD and LUSC and key pathways aberrantly regulated at both transcriptional and metabolic levels. Differential co-expression analysis revealed that loss of coherence between metabolites in tumors is a major characteristic in both LUAD and LUSC. We identified one metabolic onco-module gained in LUAD, characterized by nine metabolites and 57 metabolic genes. Multi-omics integrative analysis revealed a 28 metabolic gene signature associated with poor survival in LUAD, with six metabolite-related genes as individual prognostic markers. CONCLUSIONS: We demonstrated the clinical utility of this integrated metabolic gene signature in LUAD by using it to guide repurposing of AZD-6482, a PI3Kß inhibitor which significantly inhibited three genes from the 28-gene signature. Overall, we have integrated metabolomics and transcriptomics analyses to show that LUAD and LUSC have distinct profiles, inferred gene signatures with prognostic value for patient survival, and identified therapeutic targets and repurposed drugs for potential use in NSCLC treatment.

Complex Robotic Lung Resection.

Performing robotic thoracic lung resection is becoming an option for patients with complex thoracic disease. The robotic-assisted approach has similar survival with decreased postoperative pain, morbidity, and hospital length of stay compared with the open approach in pneumonectomy, bronchoplasty, and arterioplasty. Appropriate patient selection based on medical and surgical history combined with surgeon experience is imperative for an excellent outcome. This article will discuss the use of the robot in pneumonectomy, arterioplasty, and bronchoplasty to provide information about the technical approach and postoperative management.

Association between isolated abnormal coagulation profile on transfusion following major surgery: A NSQIP analysis of individuals without bleeding disorders.

INTRODUCTION: Preoperative coagulation screening for patients without bleeding disorders remains controversial. The combinatorial risk of INR, aPTT, and platelet count (PLT) abnormalities leading to bleeding requiring transfusion is not known in these patients. We examined the association between abnormal coagulation profile and the risk of transfusion following common elective surgery in patients without bleeding disorders. STUDY DESIGN AND METHODS: We utilized the National Surgical Quality Improvement Program (NSQIP) database from 2004 to 2018 to identify patients without a history of bleeding disorders undergoing common 23 major elective procedures across 10 specialties. Multivariable logistic regression was used to assess the association between coagulation profile and bleeding requiring packed red blood cell transfusion intra-/post-operatively. RESULTS: Of the 672,075 patients meeting inclusion criteria, 53.7% presented with normal coagulation profile preoperatively. Overall, 12.2% (n = 82,368) received transfusion. In the setting of normal aPTT/PLT, both Equivocal INR of 1.1-1.5 (aOR 1.41, 95% CI 1.38-1.44) and Abnormal INR of >1.5 (aOR 1.81, 95% CI 1.71-1.93) were significantly associated with an increased risk of transfusion. Equivocal (60-70) and Abnormal (>70) aPTT with normal INR/PLT did not demonstrate a comparable risk of transfusion. We observed a synergistic effect of combinatorial lab abnormalities on the risk of transfusion when both Abnormal INR/aPTT and Low PLT of <100,000 were present (aOR 5.18, 95% CI 3.04-8.84), compared to the effect of Abnormal INR/aPTT and normal/elevated PLT (aOR 1.90, 95% CI 1.48-2.45). DISCUSSION: The preoperative presence of abnormal findings in INR or PLT was significantly associated with the risk of bleeding requiring transfusion during intraoperative and postoperative periods.

Self-assisting robot-assisted pulmonary lobectomy has favorable outcome compared to VATS lobectomy.

Background: Open and video-assisted thoracoscopic surgery (VATS) pulmonary lobectomy requires a skilled assistant to complete the operation. A potential benefit of a robot is to allow a surgeon to complete the operation autonomously. We sought to determine the safety of performing robotic-assisted pulmonary lobectomy with self-assistance. Methods: We performed a retrospective analysis of self-assisting robot-assisted lobectomy. We evaluated the intraoperative and postoperative outcomes. We compared the outcome to the propensity matched group of patients who had VATS lobectomy. We also compared them to published outcomes of robot-assisted lobectomy. Results: 95 patients underwent self-assisted lobectomies. The median age was 70 years old, predominately female (57%) and white (85%) with 90% of patients undergoing surgery for cancer. The median of estimated blood loss was 25 mL during the operation with no conversions to open thoracotomies. After the operation, 17% of patients had major postoperative complications with a median length of stay of 2 days. At thirty-day follow-up, the readmission rate was 6.5%, with a mortality of 0%. Compared to the propensity matched VATS lobectomy group, there was significantly less conversion to open surgery (n=0, 0% vs. n=10, 12.2%, P=0.002), less intraoperative blood transfusions (n=0, 0% vs. n=6, 7.3%, P=0.03), less any complications (n=20, 24.4% vs. n=41, 50%, P=0.003), and less median length of stay (2 days, IQR 2, 5 days vs. 4 day, IQR 3, 6 days, P<0.001) in the self-assisting robot lobectomy group. Compared to published outcomes of robot-assisted lobectomy, our series had significantly fewer conversions to open (P=0.03), shorter length of stay (P<0.001), more discharges to home (93.7%) without a difference in procedure time (P=0.38), overall complication rates (P=0.16) and mortality (P=0.62). Conclusions: Self-assistance using the robot technology during pulmonary lobectomy had few technical complications and acceptable morbidity, length of stay, and mortality. This group had favorable outcome compared to VATS lobectomy. The ability to self-assist during pulmonary lobectomy is an additional benefit of the robot technology compared to open and VATS lobectomy.

Successful use of lenalidomide to treat refractory acquired von Willebrand disease associated with monoclonal gammopathy.

Acquired von Willebrand syndrome (AVWS) is a rare hematologic disorder characterized by quantitative or qualitative defects of von Willebrand factor (vWF), a protein crucial for normal hemostasis. AVWS has been described in association with several pathologic entities with varied mechanisms. Among these, lymphoproliferative disorders are the most common, with monoclonal gammopathy of undetermined significance (MGUS) being the most frequently reported. AVWS in this setting is commonly associated with the development of bleeding that is clinically challenging to manage due to accelerated clearance of vWF, limiting the utility of many conventional treatment modalities such as DDAVP or vWF/FVIII. We report a case of a 43-year-old male who was sent to our institution for new-onset easy bruising and laboratories concerning for von Willebrand disease (vWD). Further diagnostic workup revealed evidence of an IgG monoclonal gammopathy and findings suggestive of vWF inhibition. Ultimately, he was found to have monoclonal gammopathy of clinical significance (MGCS)-associated AVWS refractory to conventional treatment but responsive to lenalidomide and dexamethasone. This case suggests that lenalidomide may be suitable for patients with AVWS secondary to MGCS.

Utilization of emicizumab in acquired hemophilia A: A case report.

BACKGROUND: Acquired Hemophilia A (AHA) is a rare autoimmune disorder associated with the development of autoantibodies against factor VIII (FVIII). Although obtaining hemostatic control through the use of recombinant factor VIIa, activated prothrombin complex concentrate and recombinant porcine FVIII are cornerstones in the clinical management of AHA, these therapies have several disadvantages, including a higher risk for the development of thromboembolic events, unpredictable efficacy and short half-lives. While emicizumab has been FDA licensed for use in bleeding prophylaxis for patients with Congenital Hemophilia A (CHA) with and without inhibitors, it has not been approved for use in AHA, with only a few reports describing its use in this context. CASE REPORT: We report our experience with the use of emicizumab in an 83-year old male with AHA, complicated by the onset of atrial fibrillation following admission, drug-induced thrombocytopenia, infectious complications, and the identification of a low-grade lymphoproliferative disorder, in which emicizumab prophylaxis was used for bleeding prophylaxis in the context of persistently elevated inhibitor titers without evidence of thrombotic events or thrombotic microangiopathy.

Safety and efficacy of vagus nerve preservation technique during minimally invasive esophagectomy.

Background: This study aimed to assess the feasibility, efficacy and safety of McKeown surgery with vagal-sparing using minimally invasive esophagectomy (MIE). Methods: McKeown surgery with vagal-sparing technique using MIE was adopted on patients diagnosed with resectable esophageal cancer. From June 2020 to January 2021, a total of 20 patients from the Department of Thoracic Surgery of the National Clinical Research Center for Cancer were enrolled. Results: The study group included 17 (85%) males and 3 (15%) females, with an average age of 62.6 (±7.1) years. The most common tumor location was lower thoracic esophagus (n=9, 45%), followed by middle thoracic esophagus (n=8, 40%) and upper thoracic esophagus (n=3, 15%). Nine (45%) patients had T1b disease, followed by T2 (n=8, 40%), T1a (n=2, 10%), and Tis (n=1, 5%). The average operation time was 221.5 (±61.2) minutes. Postoperative complications were as follow: 2 (10%) with hoarseness, 2 (10%) with pulmonary infection, 1 (5%) with arrhythmia, 1 (5%) with anastomotic leakage, 1 (5%) with delayed gastric emptying, 1 (5%) with pleural effusion, and 1 (5%) with diarrhea. Dumping syndrome, cholestasis, and chylothorax were not observed, and there was no perioperative death. Conclusions: MIE with vagus nerve preservation is a feasible and safe technique, with the possibility to be an alternative for esophageal carcinoma. Further study is needed to explore the functional outcome of preserving vagus nerve.

Anatomic Pulmonary Resection is Associated With Improved Survival in Typical Carcinoid Lung Tumor Patients.

BACKGROUND: The optimal extent of resection for a patient with a typical carcinoid tumor has been controversial. Studies suggest that wedge resection is an adequate oncologic operation for this tumor type. MATERIALS AND METHODS: We analyzed the National Cancer Database to determine an optimal surgical resection for patients with a typical carcinoid tumor. We determined the number of patients who had typical carcinoid tumors. We then performed a survival analysis of the propensity-matched group of patients having a pathologic stage I typical carcinoid tumor who had undergone anatomic pulmonary resection (lobectomy and segmentectomy) or wedge resection. RESULTS: A total of 10,265 patients met the inclusion and exclusion criteria: 8956 (87%) had a typical carcinoid tumor, while 1309 patients (13%) had an atypical carcinoid tumor. Among patients with typical carcinoid tumors, there were 7163 patients (80%) who underwent anatomic pulmonary resection (6755 patients with lobectomy, 94% and 408 patients with segmentectomy, 6%) and 1793 patients (20%) who underwent wedge resection. In this cohort, patients who had an anatomic resection had significantly improved 5-y survival compared to patients who had wedge resection (91% versus 84%, P < 0.001). In the propensity score-matched group of stage I typical carcinoid tumors (n = 1348), the patients who had an anatomic resection had significantly improved survival compared to patients who had wedge resections (89% versus 85%, P = 0.01) at 5 y. CONCLUSIONS: The anatomic resection compared to wedge resection was associated with improved survival in patients with early-stage typical carcinoid lung cancer. Surgically fit patients should be considered for anatomic resection for typical carcinoid tumors.

Lobectomy Provides the Best Survival for Stage I Lung Cancer Patients Despite Advanced Age.

BACKGROUND: The Lung Cancer Study Group has shown that lobectomy provides the best survival in patients with non-small cell lung cancer. However, as patients become older, lobectomy may not provide a survival advantage compared with sublobar resection. METHODS: We analyzed the National Cancer Database for octogenarians with pathologic stage I lung cancer from 2004 to 2016. We then evaluated the patients who underwent lobectomy or sublobar (segmentectomy or wedge) resection for the treatment of cancer. We analyzed the 5-year survival rates of the groups as well as a cubic spline plot to determine age cutoffs where lobectomy does not provide improved survival. RESULTS: Among the octogenarians (227 134), there were 25 362 (26%) who had pathologic stage I lung cancer. There were 6370 (30%) patients who had sublobar resections (segmentectomy [n = 1192] and wedge resection [n = 5178]), whereas 14 594 (70%) patients had a lobectomy. There was significantly improved survival at 5 years with lobectomy compared with sublobar resection (48.5% vs 41.1%; P < .001). The cubic spline plot provided evidence that there was no age at which sublobar resection provided survival better than or equal to lobectomy (P < .001). CONCLUSIONS: In octogenarians with pathologic stage I lung cancer, lobectomy provided better 5-year survival compared with sublobar resection regardless of the age at surgical procedure. Hence, all patients with stage I cancer should be considered for a lobectomy if they are medically able to tolerate such a procedure.

Robot-assisted Thoracoscopic Lobectomy of T4 Lung Cancer.

A 79-year-old male former smoker presented with a T4 (>7 cm) adenocarcinoma of the right upper lobe. The patient was staged at clinical T4N0M0 and underwent robot-assisted right upper lobectomy and mediastinal lymph node dissection. The patient was discharged home on postoperative day 3. Larger tumors are a relative contraindication for video-assisted thoracoscopic surgical lobectomy. The robot platform overcomes the technical limitations of video-assisted thoracoscopic surgery and allows for the successful resection of large tumors.
