Objective: To define the impact of surgical margins on local recurrence (LR), distant recurrence (DR) and overall survival (OS) in patients with soft tissue sarcomas of the extremities (eSTS).

Method: Patients treated for a primary eSTS from 2006 to 2010 were analyzed. Rates of local recurrence, distant recurrence, and overall survival were estimated using the Kaplan-Meier method. The association of possible prognostic factors such as local recurrence, metastasis, and survival was performed using the Cox proportional hazards model.

Results: 128 patients were analyzed. The surgical margins were positive (R1 resection) in 22.7% and negative in 77.3%. The LR was 27%, the DR was 13% (70% of the population was free of disease at 5 years) and OS at 5 years was 84%. The prognostic factors for OS at 5 years were clinical stage, type and histological grade. The surgical margin had no impact on OS.

Conclusions: Although an adequate oncological resection cannot be underestimated, this should be considered in the decision of the optimal treatment of eSTS when amputation or significant functional impairment of the limb is required to obtain negative surgical margins.

Background: Adequate blood supply is one of the key factors for colorectal anastomosis healing. Various variants of vascular anatomy often come as a surprise to surgeons during operations.

Objectives: The aims of this study were to carry out a comparative analysis of three-dimensional-computed tomography (3D-CT) angiography data with intraoperative data and a detailed analysis of variants of the anatomy of splenic flexure.

Material and methods: In this study, we included 103 patients (56 males and 47 females; mean age 64.2 ± 11.6) with the left-sided colon and rectal cancer who underwent preoperative 3D-CT angiography at Ternopil University Hospital between 2016 and 2022.

Results: According to the recently proposed classification, there are four types of blood supply to the splenic flexure of the colon: Our analysis showed that type 1 was found in 83 (80.6%) patients, type 2 in 9 (8.7%), type 3 in 10 (9.7%), and type 4 in 1 (1%). All patients underwent local left radical hemicolectomy with resection of complete mesocolic excision (CME), central vascular ligation (CVL) and resección (R0). Seven cases were operated laparoscopically; and the median quantity of removal lymph nodes was 21.54 ± 7.32. Positive lymph nodes were revealed in 24.3% cases. AL was diagnosed in one patient.

Conclusions: Careful pre-operative analysis of vascular anatomy on 3D-CT angiography will assess the vascularization of the splenic flexure of the colon, reduce intraoperative time to identify structures, and develop a personalized strategy for surgery which potentially can reduce the risk of anastomotic leakage.

Objective: The study presents a logistic regression model describing the factors leading to intraoperative complications in laparoscopic sleeve gastrectomy (LSG) and a detailed description of the intraoperative complications that occurred in our operations.

Material and methods: The study was designed as a retrospective and cohort study. It includes patients who underwent laparoscopic sleeve gastrectomy between January 2008 and December 2020.

Results: The study included 257 patients. The mean (SD) age of all patients included in the study was 40.28 (9.58) years. The body mass index of our patients ranged from 31.2 to 86.6 kg/m2. The Stepwise Backward model was used (Cox and Snell R2 = 0.051, Nagelkerke R2 = 0.072, Hosmer-Lemesxow χ2 = 1.968, df = 4, p = 0.742, overall model accuracy of 70.4%). The model shows that pre-operative diabetes mellitus or hypertension Stage 3 significantly increases the probability or risk of intraoperative complications.

Conclusions: The study shows which intraoperative complications occur in LSG, how they can be remedied and which factors can lead to them and influence the outcome of the operation itself. The recognition and successful treatment of intraoperative complications are very important as they reduce the number of reoperations and treatment costs.

Background: The Disability of the Arm, Shoulder and Hand (DASH) questionnaire assesses the impact of upper extremity disorders on quality of life. However, its use in the Mexican population has not been formally validated.

Objective: To conduct a cultural adaptation and validation of the DASH questionnaire to evaluate the perspective of patients with neurogenic disorders of the upper extremity regarding the impact on their quality of life.

Method: We performed an adaptation of the Spanish version of the DASH questionnaire to the Mexican vocabulary and applied it to 478 volunteers. Ceiling effect, floor effect, item-total correlation, descriptive statistics of items and total score, internal consistency, precision, cross-sectional and longitudinal validity were estimated by comparing healthy controls and affected individuals with different disability levels.

Results: Our DASH questionnaire version was equivalent to those previously approved and showed homogeneity of the items with respect to the total value of the questionnaire (Cronbach's alpha > 0.96). In addition, it showed an accuracy of 7.25 points and the crosssectional and longitudinal validity was documented with significant differences between groups and subgroups with distinct disability levels.

Conclusions: The DASH questionnaire can be used with a high level of confidence in the Mexican population.

Aim: The aim of the study was to calculate the most important parameters of ulna and to determine its gender. Classifying trochlear notch joint surface types and to establish their representation in Serbian population. To determine the ideal position for olecranon osteotomy.

Material and methods: The study included 69 bones. Gender determination was performed using digital scale and photographs of the ulna. The bones weight, maximum and physiological length were measured. The place for the ideal position of olecranon osteotomy (projection of the bare area on its posterior wall) was determined on profile images.

Results: Gender related, 45 (65.21%) bones belonged to males, 24 (34.79%) ulnas belonged to females. Type I of the bare area was present in 38 (55%) ulnas, type II in 20 (29%), whereas type III was present in 11 (16%) bones. The average value for the ideal position of olecranon osteotomy was 23.02 mm. In males' ulnas, it was 23.22 mm, in females, it was 22.59 mm.

Conclusion: Type I of the bare area is the most common type of trochlear notch joint surface in Serbian population. The average value for the ideal position of olecranon osteotomy was 23.02 mm. We believe that a uniform name for the bare area should be established.

Background: Parkinson's disease is poorly studied in Colombia. It is pharmacologically managed, but for refractory cases, surgery is a therapeutic option, positively impacting on quality of life.

Objective: To determine the impact of deep brain stimulation as management in the control of progression in patients with Parkinson's disease attended our institution between the years 2014 to 2020.

Method: Descriptive retrospective study, with patients collected between 2014 and 2020 undergoing deep brain stimulation surgery. The MDS-UPDRS (Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale) was applied in the pre- and postoperative period, and the results were compared.

Results: 21 patients were included and the UPDRS was applied, finding a decrease in scores in the postoperative period. One patient had an operative site infection.

Conclusions: There was an improvement in the MDS-UPDRS score, with a low rate of complications. The procedure time was prolonged from the preoperative evaluation. Deep brain stimulation is the management of choice for refractory Parkinson's disease. The patients in this series showed improvement in their symptoms. Unfortunately, there are limitations to perform this procedure in Colombia, such as the delay in the authorization of the procedure.

Introduction: Odontoid fractures correspond to 9-15% of cervical spine fractures. Atlas fracture is rare (3-13%)⁸.

Case presentation: Male with Anderson and D´Alonzo Type II Odontoid fracture with unstable fragment treated with occipitocervical fixation with occipital plate, C2-C3 transfacet screws; Female with type E Jefferson fracture + anterolateral atloaxial dislocation, treated with occipitocervical fixation, C2-C3-C4 transfacet screws.

Discussion: Anderson and D'Alonzo Type II fractures and Jefferson type E fractures are a surgical emergency due to instability and neurological deficit.

Introduction: Epithelioid hemangioendothelioma is a rare vascular tumor with an epithelioid and histiocytoid appearance. Intestinal intussusception can manifest as chronic abdominal pain, representing only 1-5% of intestinal obstructions in adults.

Case report: 65-year-old female who is attended with chronic abdominal pain. We performed a computed tomography showing the incursion of the ileum into the right colon. She was taken to the operating table, with the finding of ileo-colic intestinal intussusception due to small bowel tumor, with subsequent anatomopathological results of epithelioid hemangioendothelioma.

Conclusions: The diagnosis and management process with an appropriate postoperative outcome is described.
