    Abstract Complete surgical resection of pancreatic neuroendocrine tumors (pNETs) has been suggested as the only potentially curative treatment. A proportion of these tumors will present late during disease progression, and invade or encase surrounding vasculature; therefore, surgical treatment of locally advanced disease remains controversial. The role of surgery with vascular reconstruction in pNETs is not well defined, and there is considerable variability in the use of aggressive surgery for these tumors. Accurate preoperative assessment is critical to evaluate individual considerations, such as anatomical variants, areas and lengths of vessel involvement, proximal and distal targets, and collateralization secondary to the degree of occlusion. Surgical approaches to address pNETs with venous involvement may include thrombectomy, traditional vein reconstruction, a reconstruction-first approach, or mesocaval shunting. Although the amount of literature on pNETs with vascular reconstruction is limited to case reports and small institutional series, the last two decades of studies have demonstrated that aggressive resection of these tumors can be performed safely and with acceptable long-term survival.

    Abstract Introduction: The omental fat-augmented free flap (O-FAFF) is a recently developed technique for autologous breast reconstruction. Our aim of the study is to evaluate the outcomes of our early case series. We assess the O-FAFF donor site morbidity in terms of postoperative pain, narcotic, and antiemetic use.
    Methods: A retrospective analysis of patients undergoing O-FAFF from 2019 to 2021 was performed. Patients were evaluated for demographic data, operative time, hospital course, and complications. Mean pain scores (1-10 scale) and narcotic pain medication use in oral morphine equivalents and doses of antiemetic medications during their hospital course were analyzed. We compared outcomes of our O-FAFF group with those of a control group of patients who underwent breast reconstruction with traditional free abdominal tissue transfer.
    Results: A total of 14 patients underwent O-FAFF breast reconstruction, representing 23 breasts. Patients had an average age of 48.5 years (±2.3 years) and body mass index of 22.6 kg/m 2 (±1.09 kg/m 2 ). Average follow-up was 232 days (±51 days). Average mastectomy weight was 245.6 g (±30.2 g) and average O-FAFF weight was 271 g (±31.7 g). Average pain scores on postoperative day 1 (POD1), POD2, and POD3 were 3.1 (±0.28), 2.8 (±0.21), and 2.1 (±0.35), respectively. The average narcotic use by patients in oral morphine equivalents on POD1, POD2, and POD3 are 24.3 (±5.5), 21.9 (±4.6), and 6.2 (±2.4), respectively. Total narcotic use during hospital stay was 79.4 mg (±11.1 mg). Average pain scores and narcotic use are significantly lower when compared with a previously published cohort of patients who underwent autologous breast reconstruction with free abdominal tissue transfer ( P < 0.05). Average antiemetic use was lower in the O-FAFF group compared with the control group: 3.5 versus 4.8 doses ( P = 0.6). Hospital length of stay was 3.0 days (±0.0 days). No complications were noted (0%). Patients were universally satisfied with their reconstructive outcome (100%).
    Conclusions: The O-FAFF is proven to be a viable method of autologous breast reconstruction. Early series of patients undergoing O-FAFF reconstruction suggest a lower donor site morbidity as demonstrated by lower postoperative pain scores and lower consumptions of narcotic pain medications.

    Abstract Background: Autologous tissue has proven advantages, however it is often not an option for women of low or normal body mass index (BMI). Omentum has been used sparingly, typically as a pedicled flap to correct breast deformities, but is considered suboptimal for full breast reconstruction. We developed a new construct, the omental fat-augmented free flap (O-FAFF) as an alternative for breast reconstruction.
    Methods: O-FAFF involves laparoscopic omentum harvesting, creation of an acellular dermal matrix shell for its encasement, and lipoinjection to augment volume. The gastroepiploic vessels are microsurgically anastomosed to internal mammary vessels. Tissue and O-FAFF construct weights as well as outcomes are reported.
    Results: Thirty-four consecutive women (50 breasts) received O-FAFF breast reconstruction after 18 unilateral and 16 bilateral mastectomies (10 non-nipple-sparing, 40 nipple-sparing). Thirty-seven were immediate and 13 were revisions of previous breast reconstructions. Patient mean age was 48.2 (range 23-73) years and mean BMI was 22.3 (range 17.6-32.4) kg/m
    Conclusions: The O-FAFF is ideally suited for women of lower BMI and could dramatically increase the number of women who are candidates for autologous breast reconstruction.

    Abstract Background: Antiplatelet therapy is used to prevent thrombosis in patients with peripheral artery disease (PAD) following revascularization. However, the current standard of care for these patients remains at the physician's discretion, varying from mono-antiplatelet therapy (MAPT) to dual-antiplatelet therapy (DAPT). Viscoelastic assays such as Thromboelastography with Platelet Mapping (TEG-PM) provide insight into individual coagulation profiles and measure real-time platelet function. This prospective, observational study looks at the differences in platelet function for patients on MAPT versus DAPT using TEG-PM.
    Methods: Patients with PAD undergoing revascularization were prospectively evaluated between December 2020 and June 2023. TEG-PM analysis compared platelet function for patients prescribed MAPT (aspirin or clopidogrel) at the initial encounter and DAPT (aspirin and clopidogrel) at the next visit. Platelet function measured in percent inhibition was evaluated at these visits, and within-group t-tests were performed.
    Results: Of the 195 patients enrolled, 486 samples were analyzed by TEG-PM. Sixty-four patients met the study criteria. At the initial visit, 52 patients had been prescribed aspirin, and 12 patients had been prescribed clopidogrel. For patients initially prescribed aspirin MAPT, an increase of 96.8%in the mean ADP platelet inhibition was exhibited when transitioning to DAPT [22.0% vs. 43.3%,
    Conclusions: Patients on DAPT showed a significant increase in platelet inhibition when compared to initial aspirin MAPT. A significant difference in AA %platelet inhibition was shown for patients on DAPT when compared to initial clopidogrel MAPT. The results show that patients may benefit from DAPT post-revascularization. Personalizing antiplatelet therapy with objective viscoelastic testing to confirm adequate treatment may be the next step in optimizing patient outcomes to reduce thrombosis in PAD patients.

    Abstract Background: Metabolic comorbidities such as diabetes and obesity are considered pro-inflammatory states which theoretically increase the risk of perioperative thrombotic events across many surgical disciplines. Currently, there is a paucity of objective metrics to determine such risk and ideal pharmacologic targets. Thromboelastography with Platelet Mapping (TEG-PM) provides a comprehensive profile of coagulation and may provide insight into clot dysregulation.
    Methods: Patients undergoing lower extremity revascularization underwent serial TEG-PM analysis. The relationship between the TEG-PM metrics and thrombosis was evaluated. Preoperative TEG-PM samples of patients with body mass index (BMI)≥25 were compared to those of patients with a normal BMI, and between patients with diabetes mellitus (DM) and those without.
    Results: 218 TEG-PM samples from 202 patients were analyzed. The BMI≥25 cohort showed significantly greater platelet aggregation [81.9% (±20.9) vs. 68.6% (±27.7), P < 0.01]. Patients with DM were more frequently on full-dose anticoagulation [47.7% vs. 29.7% P = 0.01] yet demonstrated increased clot strength, or adenosine diphosphate (ADP)-Maximum Clot Amplitude (MA) [49.1 (±16.1) vs. 41.5 (±17.1) and 37.7 (±19.6) vs. 31.6 (±17.4) P < 0.01]. 49 patients experienced thrombosis and exhibited greater platelet aggregation [76.6% (±17.8) vs. 66.8% (±30.4) P = 0.03] and greater ADP/arachidonic acid MA [47.1 (±16.6) vs. 41.9 (±18.8) and 38.2 (±17.8) vs. 32.5 (±19.9) both P = 0.05]. Patients who thrombosed were more often diabetic [69.5% versus 51.0% P = 0.03] and on full-dose anticoagulation [75.0% vs. 56.8% P = 0.02].
    Conclusions: Patients with a BMI≥ 25 and those with diabetes demonstrated TEG-PM profiles similar to patients with thrombosis. Diabetes was independently associated with thrombosis, and full-dose anticoagulation was not protective. This suggests the potential utility of TEG-PM for thrombotic risk stratification based on metabolic factors and suggests antiplatelet agents may be effective at prevention of thrombotic events in this population.

    Abstract There are a number of surgical strategies for the treatment of chronic pancreatitis. The optimal intervention should provide effective pain relief, improve/maintain quality of life, preserve exocrine and endocrine function, and manage local complications. Pancreaticoduodenectomy was once the standard operation for patients with chronic pancreatitis; however, other procedures such as the duodenum-preserving pancreatic head resections and its variants have been introduced with good long-term results. Pancreatic duct drainage via a lateral pancreaticojejunostomy continues to be effective in ameliorating symptoms and expediting return to normal lifestyle in many patients. This review summarizes operative indications and gives an overview of the different surgical strategies in treating chronic pancreatitis.

    Abstract Background: Minimally invasive distal pancreatectomy (MIDP) has established advantages over the open approach. The costs associated with robotic DP (RDP) versus laparoscopic DP (LDP) make the robotic approach controversial. We sought to compare outcomes and cost of LDP and RDP using propensity matching analysis at our institution.
    Methods: Patients undergoing LDP or RDP between 2000 and 2021 were retrospectively identified. Patients were optimally matched using age, gender, American Society of Anesthesiologists status, body mass index, and tumor size. Between-group differences were analyzed using the Wilcoxon signed-rank test for continuous data, and the McNemar's test for categorical data. Outcomes included operative duration, conversion to open surgery, postoperative length of stay, pancreatic fistula rate, pseudocyst requiring intervention, and costs.
    Results: 298 patients underwent MIDP, 180 (60%) were laparoscopic and 118 (40%) were robotic. All RDPs were matched 1:1 to a laparoscopic case with absolute standardized mean differences for all matching covariates below 0.10, except for tumor type (0.16). RDP had longer operative times (268 vs 178 min, p < 0.01), shorter length of stay (2 vs 4 days, p < 0.01), fewer biochemical pancreatic leaks (11.9% vs 34.7%, p < 0.01), and fewer interventional radiological drainage (0% vs 5.9%, p = 0.01). The number of pancreatic fistulas (11.9% vs 5.1%, p = 0.12), collections requiring antibiotics or intervention (11.9% vs 5.1%, p = 0.12), and conversion rates (3.4% vs 5.1%, p = 0.72) were comparable between the two groups. The total direct index admission costs for RDP were 1.01 times higher than for LDP for FY16-19 (p = 0.372), and 1.33 times higher for FY20-22 (p = 0.031).
    Conclusions: Although RDP required longer operative times than LDP, postoperative stays were shorter. The procedure cost of RDP was modestly more expensive than LDP, though this was partially offset by reduced hospital stay and reintervention rate.

    Abstract The escalating prevalence of lung diseases underscores the need for innovative therapies. Dysbiosis in human body microbiome has emerged as a significant factor in these diseases, indicating a potential role for synbiotics in restoring microbial equilibrium. However, effective delivery of synbiotics to the target site remains challenging. Here, we aim to explore suitable nanoparticles for encapsulating synbiotics tailored for applications in lung diseases. Nanoencapsulation has emerged as a prominent strategy to address the delivery challenges of synbiotics in this context. Through a comprehensive review, we assess the potential of nanoparticles in facilitating synbiotic delivery and their structural adaptability for this purpose. Our review reveals that nanoparticles such as nanocellulose, starch, and chitosan exhibit high potential for synbiotic encapsulation. These offer flexibility in structure design and synthesis, making them promising candidates for addressing delivery challenges in lung diseases. Furthermore, our analysis highlights that synbiotics, when compared to probiotics alone, demonstrate superior anti-inflammatory, antioxidant, antibacterial and anticancer activities. This review underscores the promising role of nanoparticle-encapsulated synbiotics as a targeted and effective therapeutic approach for lung diseases, contributing valuable insights into the potential of nanomedicine in revolutionizing treatment strategies for respiratory conditions, ultimately paving the way for future advancements in this field.
