Background:
s/Aims: This study aimed to compare the minimally invasive pancreatoduodenectomy with venous vascular resection (MI-PDVR) and open pancreatoduodenectomy with venous vascular resection (O-PDVR) for periampullary cancer.
Methods:
Data of 124 patients who underwent PDVR (45 MI-PDVR, 79 O-PDVR) between January 1, 2016, and December 31, 2023, was retrospectively reviewed.
Results:
MI-PDVR is significantly better than O-PDVR in terms of perioperative outcomes (median operation time [452.69 minutes vs. 543.91 minutes; p = 0.004], estimated blood loss [410.44 mL vs. 747.59 mL; p < 0.01], intraoperative transfusion rate [2 cases vs. 18 cases; p = 0.01], and hospital stay [18.16 days vs. 23.91 days; p = 0.008]). The complications until the discharge day showed no significant difference between the two groups (Clavien–Dindo < 3, 84.4% vs. 82.3%; Clavien–Dindo ≥ 3, 15.6% vs. 17.7%; p = 0.809). In terms of long-term oncological outcomes, there was no statistical difference in overall survival (OS, 51.55 months [95% CI: 35.95–67.14] vs.median 49.92 months [95% CI: 40.97–58.87]; p = 0.340) and disease-free survival (DFS, median 35.06 months [95% CI: 21.47–48.65] vs.median 38.77 months [95% CI: 29.80–47.75]; p = 0.585), between the two groups. Long-term oncological outcomes for subgroup analysis focusing on pancreatic ductal adenocarcinoma also showed no statistical differences in OS (40.86 months [95% CI: 34.45–47.27] vs.48.48 months [95% CI: 38.16–58.59]; p = 0.270) and DFS (24.42 months [95% CI: 17.03–31.85] vs. 34.35 months, [95% CI: 25.44–43.27]; p = 0.740).
Conclusions
MI-PDVR can provide better perioperative outcomes than O-PDVR, and has similar oncological impact.

Laparoscopic pancreatoduodenectomy (LPD) in pancreatic cancer is primarily criticized for its technical and oncological safety. Although solid evidence has not yet been established, many institutions are performing LPD for pancreatic cancer patients, with continuous efforts to ensure oncologic safety. In this video, we demonstrated a case of standard LPD combined with vascular resection in pancreatic cancer.

Purpose:
The aim of the current study was to evaluate the adverse clinical impact of intraoperative conversion during laparoscopic pancreaticoduodenectomy (LPD).
Materials and Methods:
The medical records of patients who underwent pancreaticoduodenectomy (PD) were retrospectively reviewed. Perioperative clinical variables were compared between patients who underwent converted PD (cPD) and initially planned open PD (OPD) to investigate the clinical impact and predictive factors of intraoperative conversion during LPD.
Results:
A total of 171 patients were included. Among them, 31 patients (19.3%) were found to have intraoperative conversion during LPD. Failure of progression due to severe adhesion (12 patients, 7%) and major vessel invasion (7 patients, 4%) were the two most frequent reasons for conversion. On multivariate analysis, age [Exp(β)=1.044, p=0.044] and pancreatic texture [Expa(β)=2.431, p=0.039) were found to be independent factors for predicting intraoperative conversion during LPD. In comparative analysis with the OPD group, the cPD group had a longer operation time (516.8 min vs. 449.9 min, p=0.001), higher rate of postoperative hemorrhage (12.1% vs. 0.85%, p=0.008), higher reoperation rate (9.1% vs. 0%, p=0.01), and higher cost (21886.4 USD vs. 17168.9 USD, p=0.018).
Conclusion
Intraoperative conversion during LPD can have an adverse clinical impact on the postoperative course following LPD. Appropriate patients selection and improvement of surgical techniques will be crucial for unnecessary intraoperative conversion and safe LPD.

Anesthesia and Pain Medicine 2020;15(2):233-240
Background:
Emergency reoperation is considered to be a quality indicator in surgery. We analyzed the risk factors for emergency reoperations.
Methods:
Patients who underwent emergency operations from January 1, 2017, to December 31, 2017, at our hospital were reviewed in this retrospective study. Multivariate logistic regression was performed for the perioperative risk factors for emergency reoperation.
Results:
A total of 1,481 patients underwent emergency operations during the study period. Among them, 79 patients received emergency reoperations. The variables related to emergency reoperation included surgeries involving intracranial and intraoral lesions, highest mean arterial pressure ≥ 110 mmHg, highest heart rate ≥ 100 /min, anemia, duration of operation >120 min, and arrival from the intensive care unit (ICU).
Conclusions
The type of surgery, hemodynamics, hemoglobin values, the duration of surgery, and arrival from ICU were associated with emergency reoperations.

PURPOSE: The microbial environment is an important factor that contributes to the pathogenesis of atopic dermatitis (AD). Recently, it was revealed that not only bacteria itself but also extracellular vesicles (EVs) secreted from bacteria affect the allergic inflammation process. However, almost all research carried out so far was related to local microorganisms, not the systemic microbial distribution. We aimed to compare the bacterial EV composition between AD patients and healthy subjects and to experimentally find out the beneficial effect of some bacterial EV composition METHODS: Twenty-seven AD patients and 6 healthy control subjects were enrolled. After urine and serum were obtained, EVs were prepared from samples. Metagenomic analysis of 16s ribosomal DNA extracted from the EVs was performed, and bacteria showing the greatest difference between controls and patients were identified. In vitro and in vivo therapeutic effects of significant bacterial EV were evaluated with keratinocytes and with Staphylococcus aureus-induced mouse AD models, respectively. RESULTS: The proportions of Lactococcus, Leuconostoc and Lactobacillus EVs were significantly higher and those of Alicyclobacillus and Propionibacterium were lower in the control group than in the AD patient group. Therefore, lactic acid bacteria were considered to be important ones that contribute to the difference between the patient and control groups. In vitro, interleukin (IL)-6 from keratinocytes and macrophages decreased and cell viability was restored with Lactobacillus plantarum-derived EV treatment prior to S. aureus EV treatment. In S. aureus-induced mouse AD models, L. plantarum-derived EV administration reduced epidermal thickening and the IL-4 level. CONCLUSIONS: We suggested the protective role of lactic acid bacteria in AD based on metagenomic analysis. Experimental findings further suggest that L. plantarum-derived EV could help prevent skin inflammation.

10.Acquired Partial Lipodystrophy (Barraquer-Simons Syndrome): Early Cosmetic Intervention with Autologous Fat.
Nark Kyoung RHO ; Won Serk KIM
Annals of Dermatology 2018;30(5):610-613
Barraquer-Simons syndrome is a rare acquired lipodystrophy characterized by gradually symmetric subcutaneous fat loss in a craniocaudal distribution, often associated with hypocomplementemia and nephropathies. Facial cosmetic treatment in this disorder has not been fully described in the literature. We present a patient with Barraquer-Simons syndrome with emphasis on early cosmetic intervention with autologous fat grafting and its long-term efficacy. At the follow-up 37 months after the last fat grafting, preservation of the grafted fat was noted while lipodystrophy progressed in the trunk regions. Autologous fat grafting is suggested for the correction of facial dysmorphism in this type of lipodystrophy.
