The coach's leadership has a big influence on the athlete's motivation, enthusiasm, and self-confidence in achieving the set goals. An effective leadership style in a sports context has a significant impact on athlete motivation and performance. Therefore, it is important to understand athletes' perceptions and satisfaction with their coach's leadership style. This study aims to analyze the effect of the coach's leadership style on individual athlete satisfaction by using the Leadership Sport Scale (LSS) questionnaire to measure the coach's leadership style and the Satisfaction Scale For Athletes (SSA) questionnaire to measure athlete satisfaction. This study uses a quantitative descriptive with a survey test method. The sample in this study were Student-Athletes of UKM Pencak Silat UPI in the sparring category and the single art category and sparring category, totaling 40 people. The results of data analysis show that the coach's leadership style affects individual athlete satisfaction with a percentage of 58%. Based on the results of data processing and statistical analysis in this study, it can be concluded that there is a significant influence between the coach's leadership style and the satisfaction level of individual athletes.

Aim: to evaluate the impact of primary tumor resection (PTR) on treatment outcomes in patients with asymptomatic or minimally symptomatic colorectal cancer (CRC) and synchronous unresectable metastases.Patients and Methods: treatment outcomes of patients with minimally symptomatic CRC and synchronous unresectable metastases were retrospectively assessed (2016–2022). Patients with PTR followed by chemotherapy were compared to patients receiving chemotherapy only. Survival was determined by the Kaplan-Meier method and differences were evaluated using the log-rank test and Cox proportional-hazards regression model. To reduce potential selection bias between two groups a propensity score matching (PSM) was performed.Results: no significant differences in 30-day mortality rate (р = 1,00) and the rate of surgical intervention due to complications of first treatment (р = 1,00) between the two groups. Before matching the median survivals were 27,8 and 24 months in the PTR and chemotherapy groups, respectively (р = 0,2). After PSM the overall survival rate at 3 years was 42,1% for the PTR group and 34% for the chemotherapy group (р = 0,47). The median survivals were 27,9 and 24,4 months, respectively. Three-year overall survival rate for patients with stage IVB was significantly higher in the PTR group than in the chemotherapy group (37,8% versus 4,8%; р = 0,02). The median survivals were 36,1 and 17,2 months, respectively. In multivariate analysis radical resection (R0) if unresectable metastases converted into resectable after initial treatment was the only significant prognostic factor for survival (p < 0,001).Conclusions: PTR in patients with asymptomatic or minimally symptomatic CRC and synchronous unresectable metastases is associated with acceptable postoperative morbidity and mortality rates and may improve overall survival for patients with stage IVB comparing to chemotherapy as a treatment of first line. However, randomized controlled trials are needed.

Ailm: to assess metabolic processes in the serous layer of the large intestine in the acute period of spinal injury.Materials and Methods: the experiment was carried out on laboratory animals — Wistar rats (n = 20). Spinal injury was simulated by complete transection of the spinal cord at the level of Th5-Th6 vertebrae. Metabolic changes in the intestinal wall were assessed before injury, 3 and 24 hours after spinal cord transection. Metabolism was assessed in vivo using fluorescence time-resolved macroimaging technology (macroFLIM) by autofluorescence in the spectral channel of the metabolic cofactor NAD(P)H.Results: a significant (p = 0.041) increase in the mean fluorescence lifetime (τm) by 12% and the lifetime of the long component (τ2) of the NAD(P)H cofactor by 13% (p = 0.008) was detected 24 hours after injury. MacroFLIM showed an increase in the intensity of metabolism in the large intestine wall.Conclusion: for the first time in an in vivo experiment, it has been shown that the acute period of spinal injury is accompanied by an increase in metabolic activity in the tissues of the large intestine. The revealed phenomenon confirms the role of the large intestine in compensatory reactions to spinal injury and open up new possibilities for therapy in the acute period of spinal cord injury.

Aim: to evaluate the diagnostic value of computed tomography (CT) and abdominal ultrasound (US) for chronic inflammatory complications in patients with diverticular disease (DD).Patients and Methods: the prospective cohort study included 50 patients with complicated DD. All patients underwent preoperative abdominal CT with intravenous contrast and abdominal US, with further elective bowel resection. The results of CT and ultrasound were compared with morphology of the removed specimens.Results: the sensitivity and specificity for chronic diverticulitis was 66.7% and 95.7% for CT and 100.0% and 95.7% for US. For chronic pericolic abdominal mass it was 94.8% and 90.9% for CT, 94.8% and 100.0% for US; for abdominal abscesses/cavities it was 87.5% and 96.2% for CT and 91.6% and 100.0% for US; for diverticular fistulas it was 87.5% and 100.0% for CT and 87.5% and 100.0% for US. No significant differences were obtained between two diagnostic modalities. A high level of consistency (κ-coefficient 0.71) of CT and US for the diagnosis of inflammatory complications of DD was found. Conclusion: CT and US have a similar high diagnostic value for chronic inflammatory complications of DD. Each of them can be used as a single diagnostic modality or both depending on the clinical case.

Aim: to analyze outcomes of multimodal treatment including preoperative chemotherapy with FOLFOX 4 regimen in patients with upper rectal cancer.Patients and Methods: the pilot study included 24 patients. Stages II and III were confirmed in 2 (8.3%) and 22 (91.7%) patients, respectively. All patients underwent 3 cycles of chemotherapy in FOLFOX 4 regimen followed by surgery. In the postoperative period, patients with T4 and N+ underwent adjuvant chemotherapy administered over 6 months including the time of preoperative treatment.Results: all patients completed preoperative chemotherapy with the FOLFOX 4 regimen. The toxicity of chemotherapy was 38.9%; adverse events did not exceed grades I-II. Partial tumor regression (RECIST 1.1 criteria) was achieved in 18 (75.0%) patients. All patients underwent surgery 4 weeks after chemotherapy. Postoperative complications occurred in 4 (16.7%) patients, 1 (4.2%) had grade IIIb complication (Clavien-Dindo scale), which required re-surgery. Pathological complete response (TRG1 by Mandard scale) was revealed in 1 (4.2%) patient. Thirteen patients (54.2%) received adjuvant chemotherapy. The mean follow-up was 38 (17-54) months. Three patients (12.5%) developed local recurrence and 4 (16.7%) patients — distant metastases. The 3-year overall and diseasefree survival rates were 91.7% и 79.2%, respectively.Conclusion: multimodal treatment including preoperative chemotherapy with the FOLFOX 4 regimen was well tolerated and produced tumor regression with high 3-year survival rates in patients with upper rectal cancer.

Aim: to evaluate learning curve for transanal hemorrhoidal dearterialization (THD) with mucopexy for chronic hemorrhoids II-IV stage.Patients and Methods: the THD was performed by one surgeon in 459 patients under local anesthesia in 2013- 2021. Patients were aged 45 (37;54) years, 355 (77.3%) — males. Stage II was diagnosed in 85 (18.5%) cases, stage II-III — in 47 (10.2%), stage III — in 296 (64.5%), stage III-IV and IV — in 27 (5.9%) and 4 (0.9%) cases. Regression and CUSUM analysis were used to construct the learning curve. The operation time, postoperative morbidity and recurrence rate were assessed.Results: the operation time was 25 (25;32.5) minutes, it was achieved on 210 cases. The postoperative complications occurred in 7 (1.5%) cases and were significantly often in stage III-IV and IV — 3 (9.7%) cases (p = 0.001). Recurrence was showed in 29 (6.3%) cases after 1 year of follow-up. The CUSUM function graph showed that with the experience level, a 2-fold decrease in the morbidity rate and recurrence rate was achieved after 24 and 28 procedures, respectively. When experience is achieved, the morbidity rate was low regardless of the disease stage. Despite the experience obtained, in patients operated in the 3rd and 4th quartiles, the recurrences occurred in 10 (7.7%) and 9 (8.8%) patients, respectively.Conclusion: the indicator of experience obtained is the decrease of operation time and post-op morbidity. The experience level dies not affect recurrence rate in stages III-IV due to limitations of the technique.

Aim: to assess primary results of robot-assisted ventral mesh procedure using the new Senhance® robotic system for obstructive defecation syndrome.Patients and Methods: the prospective cohort study included patients who underwent robot-assisted ventral mesh rectopexy with the Senhance® system for obstructive defecation syndrome caused by rectocele and/or rectal prolapse and/or internal intussusception. The optimal trocar sites, the location of robotic arms, operation time and intraoperative blood loss were evaluated, as well as post-op morbidity rate (Clavien-Dindo scale), pain intensity (VAS scale) and recurrence rate.Results: the study included 22 patients. Operation time was 87.1 ± 24.3 minutes. The intraoperative blood loss was 19.8 ± 9.6 ml. No conversion to open or laparoscopic approach occurred, no morbidity occurred. Pain intensity on day 1 was 0.255 mm according to VAS. No anatomical recurrence was revealed. The median follow-up period was 20.4 months (7–22 months).Conclusion: robotic-assisted ventral rectopexy using the Senhance® system is effective and safe. The results are similar to laparoscopic ones. However, the use of the Senhance® system is cost effective compared to other robotic systems.
Foreign body of the colon (case report)
Authors: Davidov M. I. 
Published: December 2023

Aim: to present a clinical case and a literature review.Patient and Methods: a 39-year-old man admitted to the clinic with abdominal pain, vomiting, urge to defecate, hiccups. He reported that a group of people forcibly injected him with an object through the anal canal. General check-up, chest and abdominal X-ray were done. The diagnosis was established: a foreign body of the rectum, sigmoid and colon. Under anesthesia, transanal removal of a foreign body was performed — a fragment of a pipe made of polymer materials with a length of 55 cm, a diameter of 6.5 cm.Results: the item was extracted completely without complications. After 2 years, the man is healthy. In the world literature, we did not find reports of such a large length of transanally removed objects.Conclusion: in the absence of peritonitis and perforation of the intestinal wall, transanal removal of a foreign body of the rectum and colon under anesthesia may be the method of choice.
