[Videofluorescence navigation during parenchymal-sparing liver resections using a domestic fluorescence imaging system]. / Videofluorestsentnaya navigatsiya pri parenkhimosokhrannykh rezektsiyakh pecheni s ispol'zovaniem otechestvennoi sistemy fluorestsentnoi vizualizatsii.

Parenchyma- sparing liver resections are aimed at maximizing the possible preservation of parenchyma not affected by the tumor - a current trend in hepatopancreatobiliary surgery. On the other hand, a prerequisite for operations is to ensure their radicality. To effectively solve this problem, all diagnostic imaging methods available in the arsenal are used, which make it possible to comprehensively solve the issues of perioperative planning of the volume and technical features of the planned operation. Diagnostic imaging methods that allow intraoperative navigation through intraoperative, instrumentally based determination of the tumor border and resection plane have additional value. One of the methods of such mapping is ICG video fluorescence intraoperative navigation. An analysis of the clinical use of the domestic video fluorescent navigation system "MARS" for parenchymal-sparing resections of focal liver lesions is presented. An assessment was made of the dynamics of the distribution of the contrast agent during ICG videofluorescent mapping during parenchymal-sparing resection interventions on the liver, with the analysis of materials from histological examination of tissues taking into account three-zonal videofluorescent marking of the resection edge, performed using the domestic videofluorescence imaging system «MARS¼.

Grade 3 Proximal Humerus Giant Cell Tumour: Is Resection and Reconstruction with Prosthesis a Valuable Option?

Grade 3 proximal humerus giant cell tumours are uncommon and the results of their surgical management with prosthetic replacement are not well established. We retrospectively studied patients with grade 3 giant cell tumours of proximal humerus treated with excision and prosthetic replacement from January 2009 and December 2018. We identified 13 patients who underwent tumour excision and prosthetic replacement. There were 7 (53.8%) men and 6 (46.2%) women. The mean age at diagnosis was 30.4 years (range 16-48 years). The mean follow-up period was 72.2 months (range 24-132). Margins were positive in 4 (30.8%) patients, ≤ 1 mm in 8 (61.5%) patients, and negative in 1 (7.7%) patient. Local recurrence was seen in 2 (15.4%) patients. 1 out of 2 (50%) patients with local recurrence had pathological fracture at presentation and margins were positive in both (100%) patients. There were 3 (23.1%) complications-1 patient with joint subluxation, 1 patient with fracture post trauma, and 1 patient with surgical site infection. The mean overall Musculoskeletal Tumour Society score was 24 out of 30 (range 21-29). Resection of grade 3 proximal humerus giant cell tumour and reconstruction with prosthesis results in low recurrence rate and good functional outcome and is a valuable treatment option for such tumours.

INTRODUCTION. The preoperative evaluation determines the health status of a patient that will undergo a surgical intervention, minimizes its risk, and optimizes the human and material resources of the perioperative scenario. OBJECTIVE. To determine the preoperative evaluation process and its ability to prevent adverse clinical events during the immediate postoperative period in adult patients undergoing a noncardiac surgical procedure. MATERIALS AND METHODS. This is a retrospective cross-sectional study. The sample of 912 medical records was calculated upon a population of 6 250 adults treated at the Carlos Andrade Marín Specialties Hospital in 2017. Inclusion criteria: patients over 18 years of age, who underwent a preoperative evaluation on an outpatient basis, and were operated on for non-cardiac interventions until January 2019, or suspension of surgery due to contraindications determined in the medical appointment. Exclusion criteria: patients under 18 years of age, not undergoing surgery, hospitalized for any reason between revision and surgery, pregnant women, and individuals with preoperative consultation outside the hospital. The computer programs used for data collection and analysis were Microsoft Excel and the International Business Machines Statistical Package for the Social Sciences. RESULTS. 82,68% (754; 912) had a previous clinical condition and 82,13% (749; 912) had a previous surgical intervention. 2,00% (18; 912) of postoperative complications were reported, and one case of death after 72 postoperative hours. No statistically significant correlation p>0,05 was found between the clinical conclusions of the preoperative control and the occurrence of postoperative complications. CONCLUSION. It was evidenced that the preoperative evaluation process was carried out systematically to patients with heterogeneous sociodemographic and clinical characteristics and there was no statistical correlation between its results and the presence of perioperative complications.

Prognostic impact of incomplete surgical clearance of radioiodine sensitive local lymph node metastases diagnosed by post-operative (124)I-NaI-PET/CT in patients with papillary thyroid cancer.

PURPOSE: Nodal involvement is an independent risk factor of recurrence in papillary thyroid cancer (PTC). Neither the international guidelines nor the recently introduced ongoing risk adaptation concept consider the extent of initial surgical clearance of radioiodine sensitive lymph node metastases in their stratification systems. We investigated the prognostic relevance of incomplete initial surgical clearance in patients with purely lymphogeneous metastatic PTC (pN1 M0) despite successful radioiodine therapy. Accurate assessment of pre-ablative nodal status was attempted using PET/CT studies with both (124)I-NaI and (18)F-FDG along with high-resolution cervical ultrasound. METHODS: Sixty-five patients with histologically diagnosed lymph node metastases (pN1 M0) were retrospectively analyzed. Patients with iodine-negative lymph node metastases diagnosed by (18)F-FDG PET/CT or distant metastases were excluded from the analysis. The association of disease recurrence with the pre-ablative nodal status, as well as other baseline characteristics, were examined applying nonparametric tests for independent samples and multiple regression analysis. Patients with persistent lymph node metastases in (124)I-NaI PET/CT were further divided according to the additional presence or absence of FDG-uptake in (18)F-FDG PET/CT. Survival analyses were performed using Kaplan-Meier curves and the Cox proportional hazards model for uni- and multivariate analyses to assess the influence of prognostic factors on progression free survival (PFS). RESULTS: Incomplete metastatic lymph node resection captured by (124)I-NaI PET/CT (n = 33) was an independent risk factor for recurrence (61 % vs 25 %, p = 0.006) and shorter PFS (46 months vs not reached, HR 4.0 [95 %-CI, 1.7-9.2], p = 0.001). Ultrasound could detect lymph node metastases only in 19/33 patients (58 %). Among patients with positive nodal status, FDG-avidity of metastatic iodine positive lymph nodes worsened the outcome (16 vs 69 months, p = 0.047). From all other investigated factors including age, N-stage (N1a vs N1b), and T-Stage (T4 vs T1-3), only large tumor size (pT4) had a significant impact on PFS (HR 2.9 [95 %-CI, 1.3-6.4], p = 0.007). CONCLUSIONS: Incomplete initial surgical clearance of lymph node metastases even after successful radioiodine therapy may increase the chances of recurrence and is an independent risk factor for impaired survival of patients with PTC. Pre-ablative (dual tracer PET/CT) imaging with (124)I-Na and (18)F provides a prognostic tool for these patients and may considerably complement the current risk stratification systems.
