RESUMEN
CASE SUMMARY: A 62-year-old man who identified as a man who has sex with men (MSM) had a 10-year history of HIV on antiretroviral therapy. He was followed up by his colorectal surgeon for a high-grade squamous intraepithelial lesion (HSIL) identified during surveillance high-resolution anoscopy (HRA). He underwent treatment with electrocautery ablation with resolution of HSIL on subsequent HRA.

BACKGROUND: Moderate carotid artery stenosis is a poorly defined risk factor for ischemic stroke. As such, practice recommendations are lacking. In this study, we describe the long-term risk of stroke in patients with moderate asymptomatic stenosis in an integrated health care system. METHODS: All adult patients with asymptomatic moderate (50%-69%) internal carotid artery stenosis between 2008 and 2012 were identified, with follow-up through 2017. The primary outcome was acute ischemic stroke attributed to the ipsilateral carotid artery. Stroke rates were calculated using competing risk analysis. Secondary outcomes included disease progression, ipsilateral intervention, and long-term survival. RESULTS: Overall, 11 614 arteries with moderate stenosis in 9803 patients were identified. Mean age was 74.2±9.9 years with 51.4% women. Mean follow-up was 5.1±2.9 years. There were 180 ipsilateral ischemic strokes (1.6%) identified (crude annual risk, 0.31% [95% CI, 0.21%-0.41%]), of which thirty-one (17.2%) underwent subsequent intervention. Controlling for death and intervention as competing risks, the cumulative incidence of stroke was 1.2% (95% CI, 1.0%-1.4%) at 5 years and 2.0% (95% CI, 1.7%-2.4%) at 10 years. Of identified strokes, 50 (27.8%) arteries had progressed to severe stenosis or occlusion. During follow-up, there were 17 029 carotid studies performed in 5951 patients, revealing stenosis progression in 1674 (14.4%) arteries, including 1614 (13.9%) progressing to severe stenosis and 60 (0.5%) to occlusion. The mean time to stenosis progression was 2.6±2.1 years. Carotid intervention occurred in 708 arteries (6.1%). Of these, 66.1% (468/708) had progressed to severe stenosis. The overall mortality rate was 44.5%, with 10.5% of patients lost to follow-up. CONCLUSIONS: In this community-based sample of patients with asymptomatic moderate internal carotid artery stenosis followed for an average of 5 years, the cumulative incidence of stroke is low out to 10 years. Future research is needed to optimize management strategies for this population.

Background: There are over 150,000 transgender adolescents in the United States, yet research on outcomes following gender-affirming mastectomy in this age group is limited. We evaluated gender-affirming mastectomy incidence, as well as postoperative complications, including regret, in adolescents within our integrated health care system. Methods: Gender-affirming mastectomies performed from January 1, 2013 - July 31, 2020 in adolescents 12-17 years of age at the time of referral were identified. The incidence of gender-affirming mastectomy was calculated by dividing the number of patients undergoing these procedures by the number of adolescents assigned female at birth ages 12-17 within our system at the beginning of each year and amount of follow-up time within that year. Demographic information, clinical characteristics (comorbidities, mental health history, testosterone use), surgical technique, and complications, including mention of regret, of patients who underwent surgery were summarized. Patients with and without complications were compared to evaluate for differences in demographic or clinical characteristics using chi-squared tests. Results: The incidence of gender-affirming mastectomy increased 13-fold (3.7 to 47.7 per 100,000 person-years) during the study period. Of the 209 patients who underwent surgery, the median age at referral was 16 years (range 12-17) and the most common technique was double-incision (85%). For patients with greater than 1-year follow-up (n=137, 65.6%), at least one complication was found in 7.3% (n=10), which included hematoma (3.6%), infection (2.9%), hypertrophic scars requiring steroid injection (2.9%), seroma (0.7%), and suture granuloma (0.7%); 10.9 % underwent revision (n=15). There were no statistically significant differences in patient demographics and clinical characteristics between those with and without complications (p>0.05). Two patients (0.95%) had documented postoperative regret but neither underwent reversal surgery at follow-up of 3 and 7 years postoperatively. Conclusion: Between 2013-2020, we observed a marked increase in gender-affirming mastectomies in adolescents. The prevalence of surgical complications was low and of over 200 adolescents who underwent surgery, only two expressed regret, neither of which underwent a reversal operation. Our study provides useful and positive guidance for adolescent patients, their families, and providers regarding favorable outcomes with gender-affirming mastectomy.

BACKGROUND: Endologix issued important safety updates for the AFX Endovascular AAA System in 2016 and 2018 owing to the risk of type III endoleaks. Outcomes with these devices are limited to small case series with short-term follow-up. We describe the midterm outcomes for a large cohort of patients who received an Endologix AFX or AFX2 device. STUDY DESIGN: Data from an integrated healthcare system's implant registry, which prospectively monitors all patients after endovascular aortic repair, was used for this descriptive study. Patients undergoing endovascular aortic repair with three AFX System variations (Strata [AFX-S], Duraply [AFX-D], and AFX2 with Duraply [AFX2]) were identified (2011-2017). Crude cumulative event probabilities for endoleak (types I and III), major reintervention, conversion to open, rupture, and mortality (aneurysm related and all cause) were estimated. RESULTS: Among 605 patients, 375 received AFX-S, 197 received AFX-D, and 33 received AFX2. Median follow-up for the cohort was 3.9 (interquartile range, 2.5-5.1) years. The crude 2-year incidence of overall endoleak, any subsequent reintervention or conversion, and mortality was 8.8% (95% confidence interval [CI], 6.3-12.3), 12.0% (95% CI, 9.1-15.9), and 8.8% (95% CI, 6.3-12.2) for AFX-S. Respective estimates for AFX-D were 7.9% (95% CI, 4.8-13.0), 10.6% (95% CI, 6.9-16.1), and 9.7% (95% CI, 6.3-14.7); for AFX2, they were 14.1% (95% CI, 4.7-38.2), 16.2% (95% CI, 6.4-37.7), and 21.2% (95% CI, 10.7-39.4). CONCLUSIONS: The midterm outcomes of a large U.S. patient cohort with an Endologix AFX or AFX2 System demonstrate a concerning rate of adverse postoperative events. Patients with these devices should receive close clinical surveillance to prevent device-related adverse events.

OBJECTIVE: Informed debate regarding the optimal use of carotid endarterectomy (CEA) for stroke risk reduction requires contemporary assessment of both long-term risk and periprocedural risk. In this study, we report long-term stroke and death risk after CEA in a large integrated health care system. METHODS: All patients with documented severe (70%-99%) stenosis from 2008 to 2012 who underwent CEA were identified and stratified by asymptomatic or symptomatic indication. Those with prior ipsilateral interventions were excluded. Patients were followed up through 2017 for the primary outcomes of any stroke/death within 30 days of intervention and long-term ipsilateral ischemic stroke; secondary outcomes were any stroke and overall survival. RESULTS: Overall, 1949 patients (63.2% male; mean age, 71.3 ± 8.9 years) underwent 2078 primary CEAs, 1196 (58%) for asymptomatic stenosis and 882 (42%) for symptomatic stenosis. Mean follow-up was 5.5 ± 2.7 years. Median time to surgery was 72.0 (interquartile range, 38.5-198.0) days for asymptomatic patients and 21.0 (interquartile range, 5.0-55.0) days for symptomatic patients (P < .001). Most of the patients' demographics and characteristics were similar in both groups. Controlled blood pressure rates were similar at the time of CEA. Baseline statin use was seen in 60.5% of the asymptomatic group compared with 39.9% in the symptomatic group (P < .001), and statin adherence by 80% medication possession ratio was 19.3% asymptomatic vs 12.4% symptomatic (P < .001). The crude overall 30-day any stroke/death rates were 0.9% and 1.5% for the asymptomatic group and the symptomatic group, respectively. The 5-year risk of ipsilateral stroke and a combined end point of any stroke/death by Kaplan-Meier survival analysis were 2.5% and 28.7% for the asymptomatic group and 4.0% and 31.4% for the symptomatic group, respectively. Unadjusted cumulative all-cause survival was 74.2% for the asymptomatic group and 71.8% for the symptomatic group at 5 years. CONCLUSIONS: In a contemporary review of CEA, outcomes for either operative indication show low adverse events perioperatively and low long-term stroke risk up to 5 years. These results are well within consensus guidelines and published trial outcomes and should help inform the discussion around optimal CEA use for severe carotid stenosis.

BACKGROUND: Obesity can often be a barrier to gender-affirming top surgery in transmasculine patients because of concern for increased surgical site complications. STUDY DESIGN: All adult patients (N = 948) within an integrated health care system who underwent gender-affirming mastectomy from 2013 to 2018 were retrospectively reviewed to evaluate the relationship between obesity and surgical site complications or revisions. RESULTS: One third of patients (n = 295) had obese body mass index (BMI), and those patients were further stratified into obesity class I (BMI of 30-34.9 kg/m2, 9.4%), class II (BMI of 35-39.9 kg/m2, 8.9%), and class III (BMI of ≥40 kg/m2, 2.9%). A majority of patients across BMI categories underwent double incision surgery. There were no significant differences in complications or revisions between patients with obesity versus those with normal BMI, when BMI was treated as a categorical or continuous variable and when evaluating only patients who underwent double incision surgery. CONCLUSIONS: Obesity alone should not be considered a contraindication for gender-affirming mastectomy. Attention should be given to several modifiable risk factors identified in this study, including lesser incision surgical techniques, tobacco use, and testosterone use. Further research is needed to understand risks associated with the highest BMI (≥40 kg/m2) patients and to assess patient satisfaction with surgical outcome.

BACKGROUND: The studies that established historical rates of surgical infection after cholecystectomy predate the modern era of laparoscopy and routine prophylactic antibiotics. Newer studies have reported a much lower incidence of infections in "low-risk" elective, outpatient, laparoscopic cholecystectomies. We investigated the current rate of postoperative infections in these cases within a large, U.S. METHODS: We retrospectively reviewed elective laparoscopic cholecystectomies from the 2016-2017 American College of Surgeons National Surgical Quality Improvement Program database. Our primary outcome was postoperative surgical site infection; secondary was Clostridium difficile infection. Logistic models evaluated the associations of patient and operation characteristics with these outcomes. RESULTS: Surgical infection occurred in 1.0% of cases (293/30,579). Cdifficile infection occurred in 0.1% (31 cases). In our adjusted multivariable models, other/unknown race/ethnicity, diabetes, hypertension, smoking, American Society of Anesthesiologists >2, operative minutes, and wound class 4 were associated with a significantly higher odds of surgical infection; no covariates were significantly associated with Cdifficile infection. CONCLUSIONS: In the setting of modern U.S. surgical practice, the incidence of infection after elective laparoscopic cholecystectomy is very low, on par with clean cases. Our study identified several patient characteristics that were strongly associated with surgical infection. Many of these are not included as risk factors in current guidelines for antibiotic prophylaxis and may help to identify those at higher risk for this rare complication.

Heart failure is the number one cause of death in the United States and a significant burden to the healthcare system. One of the primary complications of heart failure is fluid overload, for which current treatments are limited. Medical therapy is first-line; however, rates of diuretic insensitivity are high, medications are not easily titrated, and they do not address the underlying physiologic derangement that leads to hypervolemia. Removal of isotonic fluid via hemofiltration and peritoneal dialysis is an understudied but promising therapy that enables decongestion without maladaptive stimulation of fluid retention pathways. Published studies report conflicting data on long-term outcomes of ultrafiltration but reach consensus on greater and more durable volume reduction with ultrafiltration than conventional medical therapy. These studies are noteworthy for their neglect to standardize both patient selection and fluid removal protocol, which likely contribute to outcome variation. Novel technology in preclinical testing includes implantable ultrafiltration, which has potential to treat volume overload while minimizing the adverse effects associated with conventional hemofiltration. We performed a literature review of English-language studies on hemo- and peritoneal filtration for management of fluid overload in congestive heart failure. Also included is a discussion of the pathophysiology of congestive heart failure and first-line management as well as emerging technologies for ultrafiltration.

BACKGROUND: Rib resection in venous thoracic outlet syndrome (vTOS) may be approached via a transaxillary, supraclavicular, or infraclavicular approach based on surgeon preference. The purpose of this study was to evaluate long-term postoperative quality of life function after surgery for vTOS and to determine if there were long-term patency differences associated with the surgical approach or whether prophylactic postoperative venography was performed. METHODS: All patients with vTOS undergoing rib resection at a single institution were retrospectively reviewed. In 2012, we switched our approach to infraclavicular with postoperative venogram performed within 2 weeks of rib resection. Clinical records and imaging results were tabulated, and postoperative outcomes, complications, and long-term symptom follow up via the disabilities of the arm, shoulder, and hand score surveys. The disabilities of the arm, shoulder, and hand score ranges from 0 to 100 with lower numbers indicating better functional status (100 = worst). RESULTS: During the 19-year study period, we performed 109 rib resections in patients with vTOS (mean age, 29.8 years). From 2000 to 2012, 54 patients were approached via a supraclavicular approach, and from 2012 to 2018, 55 patients were approached via an infraclavicular approach. There was a significant decrease in the number of complications in the infraclavicular cohort compared with the supraclavicular group. There was no difference in patency between the 2 groups even with a higher rate of postoperative venogram in the infraclavicular cohort. There was no difference in long-term the disabilities of the arm, shoulder, and hand scores. There was an increased rate of complications in the supraclavicular cohort as compared with the infraclavicular group (P < 0.05). CONCLUSIONS: The infraclavicular approach in patients with vTOS is associated with a lower rate of complications, but long-term quality of life outcomes and patency are not different between groups.

BACKGROUND: A few observational studies have found that outcomes after esophagectomies by thoracic surgeons are better than those by general surgeons. METHODS: Non-emergent esophagectomy cases were identified in the 2016-2017 American College of Surgeons NSQIP database. Associations between patient characteristics and outcomes by thoracic versus general surgeons were evaluated with univariate and multivariate logistic regression. RESULTS: Of 1,606 cases, 886 (55.2%) were performed by thoracic surgeons. Those patients differed from patients treated by general surgeons in race (other/unknown 19.3% vs 7.8%; P<.001) but not in other baseline characteristics (age, sex, BMI, and comorbidities). Thoracic surgeons performed an open approach more frequently (48.9% vs 30.8%, P<.001) and had operative times that were 30 minutes shorter (P<.001). General surgeons had lower rates of reoperation (11.8% vs 17.2%; P=.003) and were more likely to treat postoperative leak with interventional means (6.3% vs 3.4%, P=.01). Thoracic surgeons were more likely to treat postoperative leak with reoperation (5.9% vs 3.6%, P=.01). There were no other differences in univariate comparison of outcomes between the two groups, including leak, readmission, and death. General surgery specialty was associated with lower risk of reoperation. Our multivariable model also found no relationship between general surgeon and risk of any complication (odds ratio 1.10; 95% CI .86 to 1.42). DISCUSSION: In our large, national database study, we found that outcomes of esophagectomies by general surgeons were comparable with those by thoracic surgeons. General surgeons managed postoperative leaks differently than thoracic surgeons.

Tumors of the posterior mediastinum, particularly when involving the neural foramina, are typically resected via thoracotomy or by a hybrid method with a combination of video-assisted thoracoscopy and open surgery. However, in the appropriate anatomic and clinical context, a video-assisted thoracoscopic approach may be feasible, and such an approach may decrease postoperative pain and hospital length of stay. We present a patient with a benign schwannoma of the thoracic inlet and posterior mediastinum with symptomatic mass effect on surrounding structures. Extensive interdisciplinary discussion with the patient resulted in a minimally invasive, anterior surgical approach. We discuss the unusual surgical approach, complications, and recommendations for future similar cases.
RESUMEN
BACKGROUND: Intercostal nerve blockade (INB) for thoracic surgery analgesia has gained popularity in practice, but evidence demonstrating its efficacy remains sparse and inconsistent. We investigated the effect of INB with standard bupivacaine (SB) with epinephrine versus liposomal bupivacaine (LB) versus a mixed solution of the two on postoperative pain control and outcomes in video assisted thoracoscopic lobectomy patients. METHODS: Since 2014, our practice has shifted from using INBs with SB with epinephrine, to LB, to a mix of the two as the central component of multimodal analgesia after video assisted thoracoscopic surgery. The blocks are performed in a standardized fashion under thoracoscopic visualization consecutively from two rib spaces above to two below the outermost incisions. We retrospectively compared all minimally invasive lobectomies performed at our institution between January 2014 and July 2018 by type of local anesthetic used for INB. We examined median length of stay (LOS), opioid utilization, and subjective pain scores [0-10]. RESULTS: Out of 302 minimally invasive lobectomy patients, 34 received SB with epinephrine, 222 received LB alone, and 46 received the mixed solution. LOS was almost a full day shorter in the LB group than in the SB group (34.8 vs. 56.5 hours, P=0.01). There was nearly 25% lower median total morphine equivalent utilization in the mixed solution cohort compared to the LB cohort (-7.1 mg, P=0.02). Additionally, IV morphine equivalent utilization was over 50% lower in the mixed solution group than in the SB with epinephrine group (-10.0 mg, P=0.03). CONCLUSIONS: Our study is by far the largest (N=302) to compare types of local anesthetic used for INB within a uniform case population. The reductions in LOS and opiate utilization observed in our study among patients receiving LB-based formulations were both statistically and clinically significant.
RESUMEN
Type 1 diabetes mellitus is a common and highly morbid disease for which there is no cure. Treatment primarily involves exogenous insulin administration, and, under specific circumstances, islet or pancreas transplantation. However, insulin replacement alone fails to replicate the endocrine function of the pancreas and does not provide durable euglycemia. In addition, transplantation requires lifelong use of immunosuppressive medications, which has deleterious side effects, is expensive, and is inappropriate for use in adolescents. A bioartificial pancreas that provides total endocrine pancreatic function without immunosuppression is a potential therapy for treatment of type 1 diabetes. Numerous models are in development and take different approaches to cell source, encapsulation method, and device implantation location. We review current therapies for type 1 diabetes mellitus, the requirements for a bioartificial pancreas, and quantitatively compare device function.

BACKGROUND: Port catheters are often used for patients who require long-term central venous access. However, thick subcutaneous fat may obscure the port location and limit the degree to which the port is palpable. We describe a method to improve port catheter placement in overweight and obese patients. METHODS: Port catheters were placed in three overweight and obese patients after a diagnosis of malignancy. Rather than securing the port onto muscular fascia as is typically done, securing sutures were directed toward the dermis, elevating the port toward the skin and creating skin dimpling for visual reference. RESULTS: There were no intra- or postoperative complications. The ports remain visible and palpable >9â¯months after placement and there have been no reported difficulties with access. CONCLUSION: This method improves visualization of the port location and facilitates palpation of the port during Huber needle access.

Adequate reconstruction of sternal defects is critical for function and quality of life. Reconstructive techniques have historically included a rigid component, most often a synthetic prosthesis, but these are associated with complications related to presence of a foreign body and the loss of native bone's flexibility and growth capability. Recently, biologic mesh has been used as an alternative for reconstructions of the chest wall, but not the sternum. We present the case of a large sternal defect after chondrosarcoma resection reconstructed with porcine acellular dermal matrix and soft tissue flaps, without rigid component, and with excellent patient outcome through 2 years of follow-up.

Importance: Given the risks of postoperative morbidity and its consequent economic burden and impairment to patients undergoing colon resection, evaluating risk factors associated with complications will allow risk stratification and the targeting of supportive interventions. Evaluation of muscle characteristics is an emerging area for improving preoperative risk stratification. Objective: To examine the associations of muscle characteristics with postoperative complications, length of hospital stay (LOS), readmission, and mortality in patients with colon cancer. Design, Setting, and Participants: This population-based retrospective cohort study was conducted among 1630 patients who received a diagnosis of stage I to III colon cancer from January 2006 to December 2011 at Kaiser Permanente Northern California, an integrated health care system. Preliminary data analysis started in 2017. Because major complication data were collected between 2018 and 2019, the final analysis using the current cohort was conducted between 2019 and 2020. Exposures: Low skeletal muscle index (SMI) and/or low skeletal muscle radiodensity (SMD) levels were assessed using preoperative computerized tomography images. Main Outcomes and Measures: Length of stay, any complication (≥1 predefined complications) or major complications (Clavien-Dindo classification score ≥3), 30-day mortality and readmission up to 30 days postdischarge, and overall mortality. Results: The mean (SD) age at diagnosis was 64.0 (11.3) years and 906 (55.6%) were women. Patients with low SMI or low SMD were more likely to remain hospitalized 7 days or longer after surgery (odds ratio [OR], 1.33; 95% CI, 1.05-1.68; OR, 1.39; 95% CI, 1.05-1.84, respectively) and had higher risks of overall mortality (hazard ratio, 1.40; 95% CI, 1.13-1.74; hazard ratio, 1.44; 95% CI, 1.12-1.85, respectively). Additionally, patients with low SMI were more likely to have 1 or more postsurgical complications (OR, 1.31; 95% CI, 1.04-1.65) and had higher risk of 30-day mortality (OR, 4.85; 95% CI, 1.23-19.15). Low SMD was associated with higher odds of having major complications (OR, 2.41; 95% CI, 1.44-4.04). Conclusions and Relevance: Low SMI and low SMD were associated with longer LOS, higher risk of postsurgical complications, and short-term and long-term mortality. Research should evaluate whether targeting potentially modifiable factors preoperatively, such as preserving muscle mass, could reverse the observed negative associations with postoperative outcomes.

Mucor is a ubiquitous fungus that is non-pathogenic in healthy people. In immunocompromised hosts, non-functional or absent neutrophils and macrophages result in fungal invasion and infection [1]. Invasive mucor (mucormycosis) most commonly involves the sinuses, brain, or lungs. Pulmonary mucormycosis typically presents in patients with a history of organ transplantation or hematologic malignancy [2], and is rare in patients with diabetes alone. The epidemiology and management of pediatric pulmonary mucormycosis is poorly described. We report an unusual occurrence of this disease, complicated by segmental pulmonary artery thrombus in a 15-year-old with poorly controlled diabetes. His severe, medication-resistant infection was ultimately treated successfully with antifungal medication combined with aggressive surgical debridement. The pulmonary artery segmental thrombus resolved after treatment of the underlying infection without anticoagulation.
RESUMEN
CONTEXT: Progel Pleural Air Leak Sealant (CR Bard, Warwick, RI) is a US Food and Drug Administration-approved hydrogel designed for application to surgical staple lines to prevent air leak after lung surgery. This product has demonstrated efficacy in reducing intraoperative air leaks compared with standard air leak closure methods. However, the impact on chest tube duration and length of hospital stay has not been reported. OBJECTIVE: To evaluate the effect on rates of postoperative air leak, chest tube duration, and hospital stay in surgical patients with and without use of Progel. DESIGN: Retrospective study of 176 patients aged 18 to 80 years who underwent video-assisted thoracoscopic wedge resections between 2014 and 2016. Eighty-four (48%) cases using Progel were included, as well as a representative sample of non-Progel cases (n = 92; 52%). MAIN OUTCOME MEASURE: Presence of postoperative lung air leak. RESULTS: No difference existed between the Progel and non-Progel groups in the rate of postoperative air leak (20/84, 23.81% Progel; 16/92, 17.39% non-Progel; p = 0.33). The length of time patients had a chest tube was similar (23.5 vs 23 hours, p = 0.721), as was percentage of patients with a less than 2-day hospitalization (77.17% non-Progel vs 82.14% Progel, p = 0.414). CONCLUSION: Our results suggest that Progel, used routinely in patients undergoing nonanatomic lung resection, does not have a significant impact on postoperative air leak, chest tube duration, or length of hospital stay. Further studies are warranted to evaluate the utility of Progel in reducing postoperative complications after thoracoscopic wedge resection in those treated for air leak or in the reduction of postoperative air leak in high-risk patients.

We report unusual cases of brainstem encephalitis in two young boys. Both presented with acute febrile illness, progressive encephalopathy, and marked cerebrospinal fluid pleocytosis. Case one shared some of the clinical features that have been seen in previously reported cases of brainstem encephalitis, such as ophthalmoplegia, ataxia, and progressive encephalopathy. Case two presented with similar clinical features, although without ophthalmoplegia and ataxia. A review of magnetic resonance imaging revealed mild differences with respect to anatomic lesion localization and confirmed a neuroanatomic basis for the variance in each patient's symptoms. The features of these cases deviate from the classical symptoms described in the Miller-Fisher syndrome/Bickerstaff brainstem encephalitis/Guillain-Barré syndrome spectrum, although the cause for variability in clinical phenotypes is unknown.
