Abstract The “triple threat” surgeon—one who excels as a clinician, researcher, and educator—has long represented the ultimate achievement in academic medicine. This model has guided generations of surgeons aspiring to excellence. The importance of leadership skills has also been recognized, leading to the modern concept of the “quadruple threat.” Over the last decades, many challenges have threatened the existence of this model, including increasing competition for limited funding, declining reimbursement, and increasing administrative burdens. While some view the “triple threat” unachievable or unsustainable in the current environment, others use this as an opportunity to adapt the model to contemporary practice. This review examines the historical origins of the triple threat surgeon, the current challenges to this model and the steps necessary to ensure its success.

Abstract Selective myectomy has gained popularity for treating facial synkinesis. We examined the combined effectiveness of depressor anguli oris (DAO), partial buccinator, and platysma myectomies. Retrospective case series. Pre- and postoperative botulinum toxin-A (BTX-A) treatments of selective myectomy patients were collected. Facial photographs were analyzed using Emotrics + . Facial Asymmetry Index (FAI) and electronic facial paralysis assessment (eFACE) scores were calculated. Twenty patients underwent myectomies. Improvements (mean ± standard error) were seen in several smile metrics, including FAI by 2.80 ± 0.68 mm, nasolabial fold angle by 4.78 ± 1.83 degrees, and smile angle by 4.43 ± 1.18 degrees (all p < 0.05). Postoperative FAI was 2.79 mm. Total BTX-A decreased by 10.85 ± 4.48 units (p = 0.03). eFACE revealed improved oral commissure movement and platysmal synkinesis (p < 0.05 for both). Combined myectomies of the DAO, partial buccinator, and platysma clinically and statistically improve smile in facial synkinesis.

Abstract The da Vinci Single-Port (SP) system is a robotic surgery platform that allows access into the abdominal cavity through a single short surgical incision. The omentum is an attractive donor site for vascularized omental lymph node transfer (VOLT) in the treatment of lymphedema. We hypothesize that SP robotic VOLT will allow for improvement in perioperative outcomes as compared to open laparotomy for omental flap harvest. A retrospective cohort study was performed, comprised of a study sample of patients with a diagnosis of lymphedema who presented to our institution for VOLT using either an open or SP robotic technique between May 2020 and February 2023. The primary outcome was length of hospital stay. The secondary outcomes included intraoperative complication rate, postoperative complication rate, and length of surgery. Fifteen patients underwent da Vinci SP omental flap harvest, and 14 patients underwent open harvest. There was no significant difference in average age, BMI, sex, or lymphedema etiology between the two groups. Average length of stay was 2.2 ± 1.7 days in the SP group and 2.3 ± 2.1 days in the open group (p = 0.91). There were no significant differences in terms of intraoperative or postoperative complications between the two groups. Ninety-three percent of SP robotic and 86% of open patients reported at least partial subjective improvement following VOLT (p = 0.50). Our findings suggest that SP robotic omental harvest for VOLT is feasible. Perioperative outcomes show comparable results in terms of length of hospital stay, complications, and subjective postoperative improvement when comparing the open to the SP approach.

AbstractPostoperative (or postprocedural) pneumocephalus is unique from those associated with head injury, spontaneous cerebrospinal fluid leaks, and intracranial infection. Postoperative cranial imaging usually demonstrates a small volume of air that remains in the surgical bed, which is essentially self-limited and resolves over several weeks or less. However, occasionally, surgical defects lead to symptomatic postoperative air entrapment, and severe cases are generally due to one-way valves created by tissue, a mechanism shared with severe traumatic pneumocephalus. In the case where this causes progressive pressurization, this is termed tension pneumocephalus, analogous to its pulmonary counterpart. In the closed adult cranium, the Monroe-Kellie doctrine can be extended to include pneumocephalus if the compressible nature of gas is accounted for. Three illustrative cases are used to highlight common etiologies of postoperative tension pneumocephalus, management strategies, and imaging findings of these collections.

Abstract The environmental impact of computer-aided diagnosis (CADx) in colonoscopy is unknown. The potential to reduce greenhouse gas emissions by limiting unnecessary polypectomies may be offset by emissions associated with CADx devices. We quantified and compared the carbon footprint of colonoscopy with and without CADx. Life-cycle carbon emissions associated with endoscopic snares, polyp traps, histopathology, and CADx devices were estimated using life-cycle assessment software. The effect of CADx was estimated by the carbon dioxide equivalent (CO2e) emissions related to outcomes from a prospective cohort of patients who underwent colonoscopy with optical diagnosis under a leave-in-situ strategy (i.e. rectosigmoid polyps ≤5 mm predicted as non-neoplastic were not removed) with and without CADx assistance. We analyzed 1134 individuals (median age 67 years, 59% male) with 1716 colorectal polyps. Colonoscopy with CADx reduced the number of snares and polyp traps from 567 to 543 (difference: 24) and histopathology submissions from 1343 to 1278 (difference: 65). However, the total carbon footprint increased from 832 kg CO2e (95%CI 815 to 847) without CADx to 946 kg CO2e (95%CI 927 to 965) with CADx, corresponding to an absolute increase of 114 kg CO2e (95%CI 80 to 150) or 0.10 kg CO2e per colonoscopy. Using CADx under a leave-in-situ strategy increased the environmental burden of colonoscopy.

Abstract Pain is a common postpartum complaint, yet data suggest that approaches to postpartum pain management vary widely. Given the goal of improving quality and equity in postpartum pain management, we aimed to examine whether and how clinicians' perspectives on postpartum pain management differed by clinician roles. This is a qualitative study at a large, tertiary, and academic medical center. From November 2021 to June 2022, obstetric clinicians, including attending physicians, trainee physicians, and advanced practice providers (APPs), were recruited to complete in-depth interviews regarding their clinical experience managing postpartum pain using a semi-structured interview guide. Participants were asked to reflect both on their own role and that of the other clinician types. Purposive sampling was used to enroll a cohort representative of the institutional workforce in terms of clinician type and demographics. Data were analyzed using the constant comparative method. Of 46 participants, 47.8% (n = 22) were attending physicians, and 91% (n = 42) were female. Emergent themes were both self-reflected and externally directed. Data demonstrated that postpartum pain management differs by clinician type and level of experience. Themes related to the role of attending physicians included responsibilities as teachers for trainees, supervisory roles, and perceptions that attendings have greater comfort with prescribing opioids. Themes related to the role of trainee physicians included the impact of patient load on trainees' management, limitations of morning rounds, familiarity with emerging data, and perceptions of hesitancy to prescribe opioids. Themes related to the role of APPs included less reliance on opioids for postpartum pain management and emphasis on nonpharmacological approaches. Perspectives on postpartum pain management vary by clinician role. Consideration of these differences and the interplay between roles is essential when examining opioid prescribing patterns and developing interventions to improve postpartum pain management.

Abstract Purpose :Tamoxifen undergoes bioactivation to its active metabolite (Z)-endoxifen, which blocks estrogen-dependent breast tumor growth at high potency. We tested the feasibility and safety of supplementing standard tamoxifen therapy with low-dose (Z)-endoxifen in patients with breast cancer with compromised tamoxifen bioactivation. Patients and Methods :We conducted a prospective, interventional, three group randomized trial including 235 patients with hormone receptor–positive breast cancer who received standard tamoxifen therapy (20 mg/day). Patients were stratified by CYP2D6 genotype (n = 78), defining poor, intermediate, and normal metabolizers, or by baseline (Z)-endoxifen plasma concentration (n = 78), defining ≤15, 15 to 25, and ≥25 nmol/L. Co-treatment with (Z)-endoxifen 3 and 1.5 mg/day or placebo was performed, respectively. A control group (n = 79) received placebo regardless of metabolizer phenotype. The primary endpoint was the number of patients with (Z)-endoxifen levels &gt;32 nmol/L after 6 weeks of treatment. Adverse events were continuously monitored. Results: A higher proportion of patients in both intervention groups achieved target concentrations &gt;32 nmol/L compared with control (P &lt; 0.0001). At 3 mg (Z)-endoxifen supplementation, 92.3% of CYP2D6 poor metabolizer patients and all patients with baseline (Z)-endoxifen ≤15 nmol/L achieved the target concentration. At 1.5 mg (Z)-endoxifen supplementation, 88% of CYP2D6 intermediate metabolizer patients and 95% of patients with 15 to 25 nmol/L baseline (Z)-endoxifen levels achieved the target concentration. Similar proportions of patients receiving (Z)-endoxifen (6/80, 7.5%) or placebo (8/155, 5.2%) experienced grade 3 adverse events. Conclusions: Adding low-dose (Z)-endoxifen to standard tamoxifen is safe and provides a new approach to personalized antiestrogen treatment for patients with low endoxifen plasma levels.

AbstractThumb carpometacarpal (CMC) arthritis is a common and sometimes debilitating condition with a variety of surgical treatments. Pyrocarbon thumb CMC hemiarthroplasty is one option, which has demonstrated promise; however, no long-term outcomes have been reported.We performed a retrospective institutional review of 106 primary thumb CMC pyrocarbon hemiarthroplasties with a minimum of 1 year, median 6.1-year follow-up. We analyzed rates of pain relief, reoperation, and implant failure as well as biomechanical, radiographic, and patient-reported outcomes.Pain was significantly decreased after surgery. Radial and palmar abduction were modestly improved postoperatively (increased from 40–50 degrees). Implants showed high rates of radiographic osteolysis (53%) and subsidence (44%). Two-, 5-, and 10-year rates of reoperation (18, 21, 21%) and implant removal (15, 19, and 19%), respectively.Pyrocarbon thumb CMC hemiarthroplasty provides high rates of pain relief and preservation of pinch and grip strength. Patients had modest improvement in radial and palmar abduction; however, hemiarthroplasty was associated with moderate rates of reoperation and implant revision.Therapy Level IV.
