Outcome and Factors Related to Isolated Liver Metastasis due to Breast Cancer.

OBJECTIVE: To determine the associated risk factors for isolated liver metastasis in breast cancer patients and to detect the prognostic factors related to survival. STUDY DESIGN: Analytical study. Place and Duration of the Study: Department of General Surgery, The University of Health Sciences, Istanbul, Turkiye, from January 2011 to November 2020. METHODOLOGY: Patients with breast cancer liver metastasis who experienced surgery were retrospectively analysed for breast cancer and metastases-related characteristics. Descriptive statistical methods were used in the evaluation of data. Survival analyses were estimated by the Kaplan-Meier method. Log-rank and univariable Cox regression tests were utilised to search for prognostic factors' impact on survival. RESULTS: Out of 12 patients, 11 had recurrent disease after a median of 36 months of disease-free survival (DFS) and one patient had de novo metastasis. Grade 3 tumours and increased expression of Ki-67 had a negative effect on DFS. The median follow-up period was 66 months. Survival analysis showed 2- and 3-year progression-free survival (PFS); overall survival rates were 82%, 69%, 92%, and 82%, respectively. Development of liver metastasis in 3 years following breast cancer treatment was linked to worse PFS (p = 0.040). CONCLUSION:  Long-term survival is possible for breast cancer survivors with liver metastasis. Disease-free interval is an important determinant. Longer progression-free survival was detected in patients who had developed metastasis after three years of breast cancer treatment. KEY WORDS: Breast cancer, Liver metastasis, Hepatic surgery.

Clinical significance of the histopathological metastatic largest lymph node size in colorectal cancer patients.

Background: The metastatic lymph nodes (MLN) are interpreted to be correlated with prognosis of the colorectal cancers (CRC). The present retrospective study aimed to investigate the clinical significance of the largest MLN size in terms of postoperative outcomes and its predictive value in the prognosis of the patients with stage III CRC. Methods: Between May 2013 and December 2018, a total of 101 patients who underwent curative resection for stage III CRC retrospectively reviewed. All patients were divided into two groups regarding cut-off value (<1.05 cm and ≥1.05 cm) of maximum MLN diameter measured histopathologically. A comparative analysis of demographic and clinicopathological characteristics of the patients and their postoperative outcomes were performed. Results: Two groups carried similar demographic data and preoperative laboratory variables except the lymphocyte count, hematocrit (HCT) ratio, hemoglobin level and mean corpuscular volume (MCV) value (p<0.05). The patients with MLN diameter ≥1.05 cm (n=46) needed more erythrocyte suspension and were hospitalized longer than the patients with a diameter <1.05 cm (n=55) (p=0.006 and 0.0294, respectively). Patients with MLN diameter < 1.05 cm had a significantly longer overall survival than patients with MLN diameter ≥ 1.05 cm (75,29 vs. 52,57 months, respectively). Regarding the histopathologic features, the patients with MLN diameter ≥1.05 cm had larger tumor size and higher number of MLN than those with diameter <1.05 cm (p=0.049 and 0.001). Conclusion: The size of MLN larger than 1.05 cm may be predictive for a poor prognosis and lower survival of stage III CRC patients. The largest MLN size may be a proper alternative factor to the number of MLNs in predicting prognosis or in staging CRC patients.

The Impact of Metabolic 18F-Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography Parameters on the Prognosis of Resectable Pancreatic Adenocarcinoma.

Objectives: 18F-fluorodeoxyglucose (FDG)-positron emission tomography/computed tomography (PET/CT) is a useful staging method in pancreatic cancer. The prognosis of pancreatic adenocarcinoma is affected by the tumor stage and resectable state. Maximum standardized uptake value (SUVmax), metabolic tumor volume (MTV), and total lesion glycolysis (TLG) of primary tumors are related to prognostic parameters in pancreatic cancer. This study compared 18F-FDG PET/CT findings with prognostic factors and overall survival of patients with pancreatic cancer. Methods: Patients with pancreatic adenocarcinoma, referred to our department between 2015 and 2022 for staging, were retrospectively evaluated. Head-to mid-thigh PET/CT images were obtained 1 h after 18F-FDG injection. Demographic data, survival, and clinical and pathological findings of 39 patients, who underwent surgery after PET/CT imaging, were collected. All primary tumor MTV, SUVmax, background SUVmax, and TLG data have were measured. Results: The images of 39 patients (24 women and 15 men) with a mean age of 66.62±9.60 years were evaluated. The mean SUVmax, MTV 40%, and TLG of the primary tumors in the pancreatic tissue were 6.28±2.33, 19.33±9.77, and 66.56±45.99, respectively. The average survival after disease diagnosis was 18.97±11.47 (2-55) months. MTV and TLG were significantly higher in patients who died during our study. SUVmax has a significant effect on mortality. Conclusion: 18F-FDG PET/CT metabolic parameters of SUVmax, MTV, and TLG could help predicting the prognosis of pancreatic cancer preoperatively and follow-up in patients with resectable tumors. Additionally, in our study group tumor grade and perineural invasion significantly affected overall survival.

The value of radioembolisation therapy on metastatic liver tumours - a single centre experience.

OBJECTIVE: Local treatments used in metastatic liver tumours efficiently control the disease and survival. Transarterial radioembolisation (TARE) is a safely used locoregional treatment method. We aim to investigate the impact of TARE on different kinds of metastatic liver tumours and the effect of pre-treatment clinical findings. MATERIAL AND METHODS: The patients with metastatic liver tumours referred to our department for radioembolisation were retrospectively evaluated. All patients were given a Y-90 glass microsphere after being selected by the appropriate clinical and imaging criteria, lung shunt fraction levels, vascular investigation, and macro aggregated albumin (MAA) scintigraphy performed in the angiography unit. RESULTS: Thirty-four (17 women, 17 men) patients were suitable for the treatment. Patients were treated with 115.88±47.84 Gy Y-90 glass Microspheres. The mean survival rate was 14.59±12.59 months after treatment. Higher survival rates were detected in patients who had higher pre-treatment serum albumin levels. The optimum cut-off value of albumin to predict response to treatment was 4 g/dl with 88.89% sensitivity, 62.50% specificity, 72.73% PPV and 83.33% NPV. Furthermore, one unit increase in age increased mortality 1.152 times in our patient group. CONCLUSION: Radioembolisation is a safe and efficient method for controlling metastatic liver disease. Albumin levels significantly affect predicting response; higher albumin levels are related to higher survival rates. Furthermore, older age positively correlated with mortality rates in our patient group.

Respiratory muscle strength and pulmonary function in unvaccinated athletes before and after COVID-19 infection: A prospective cohort study.

PURPOSE: We investigated abnormalities and recovery in respiratory function after COVID-19 infection in an unvaccinated elite athlete population. METHODS: Measurements included maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), and peak expiratory flow (PEF). RESULTS: The most frequent reported symptoms were fatigue with 80% and muscle/joint pain and headache with 50%, whereas only 10% reported dyspnoea and 30% cough. During follow-up, MIP was up to 13% and MEP up to 8% lower following COVID-19 infection. Likewise, FEV1 was up to 2% and FVC up to 5% lower. While MEP and FEV1 rapidly normalised, MIP and FVC still remained abnormal after 52 days of COVID-19 infection, thereby leading to a restrictive ventilatory pattern. PEF seemed unaffected during follow-up. CONCLUSIONS: COVID-19 decreases respiratory function in unvaccinated athletes despite reporting few respiratory symptoms and having mild disease. An initiative aimed at reducing the long-term adverse effects following COVID-19 infection seems warranted, which perhaps may be avoided through vaccination.

Primary pancreatic hydatid disease: A rare presentation of echinococcosis.

Hydatid disease is a zoonotic parasitic disease which rarely involves pancreas primarily. Diagnosis of pancreatic hydatid cyst is a challenge and operative skills are important to avoid spillage of cyst's content. A 19-year-old male patient was admitted to hospital with recurrent abdominal pain which was on epigastrium and left upper quadrant of abdomen. Pain was not associated with nausea, vomiting or fever. An abdominal computed tomography (CT) scan was ordered. As a result of abdominal CT scan, there was a cystic area in tail of pancreas with a diameter of 5.6 cm which includes septa and there was calcification on borders of the cyst. Possible diagnosis were either pancreatic hydatid disease, pancreatic cyst adenoma or cystadenocarcinoma or pseudocyst of autoimmune pancreatitis. Whole body positron emission tomography (PET-CT) scan showed no other cyst or lesion other than pancreatic cyst. Hydatid disease indirect hemagglutination test has been studied and it was positive. Imaging studies and laboratory results were suggested hydatid disease and laparoscopic distal pancreatectomy has been applied. Primary pancreatic hydatid disease should be in differential diagnosis when newly appearing pancreatic cyst has been diagnosed, especially in endemic areas. Appropriate surgical technique has to be applied to avoid dissemination of cyst's content.

Effects of Core Training in Physical Fitness of Youth Karate Athletes: A Controlled Study Design.

This study aimed to analyse the impact of an 8-week core strength training (CST) programme in youth karate practitioners on core endurance, agility, flexibility, sprinting, jumping, and kick performance. This study followed a randomized parallel design. Twenty-nine participants (age: 12.86 ± 0.81 years old; height: 152.55 ± 10.37 cm; weight: 42.93 ± 8.85 kg) were allocated to a CST programme (n = 16) performed thrice weekly or to a control group (n = 13) only performing the sport-specific (karate) training. Participants were assessed three times (baseline, mid and post-intervention) for the following tests: (i) flexor endurance test (FET); (ii) back extensor test (BET); (iii) lateral musculature test (LMT); (iv) flexibility; (v) chance of direction (COD); (vi) countermovement jump (CMJ); (vii) back muscle strength (BMS); (viii) horizontal jump (LJ); (ix) sprint test; and (x) karate kick test (KKT). Between-group analysis revealed significant advantages for the CST group on the FET (p < 0.001), BET (p < 0.001), LMT (p < 0.001), 20 m sprint (p = 0.021) and KKT for right (p < 0.006) and left (p < 0.020) legs. No significant differences were found between groups in the remaining physical fitness variables (p > 0.05). The within-group changes revealed significant improvements in the CST group at flexibility (p = 0.002), COD (p < 0.001), CMJ (p < 0.001), BMS (p < 0.002), 20 m sprint (p = 0.033), and KKT (p < 0.001). In addition, within-group changes in the control group were also significant in flexibility (p = 0.024) and right kick (p < 0.042). We conclude that the CST programme improves core endurance and karate kick performance; however, it is not effective enough for other physical performance parameters in KR practitioners.

Post-Operative Results of ACL Reconstruction Techniques on Single-Leg Hop Tests in Athletes: Hamstring Autograft vs. Hamstring Grafts Fixed Using Adjustable Cortical Suspension in Both the Femur and Tibia.

Background and Objectives: Anterior cruciate ligament (ACL) tears are common injuries in the athletic population, and accordingly, ACL reconstruction (ACLR) is among the most common orthopedic surgical procedures performed in sports medicine. This study aims to compare the semitendinosus/gracilis (ST/G) and ACL hamstring grafts fixed using adjustable cortical suspension in both the femur and tibia (MAI) ACLR techniques. We aimed to compare the results of single-leg hop tests (SLHT) applied in different directions and limb symmetry indices (LSI) in athletes with a 6-month post-operative ACLR history. Materials and Methods: A retrospective cohort of 39 athletes from various sports branches who underwent MAI (n = 16) and ST/G (n = 23) ACLR techniques by the same surgeon were evaluated. The knee strength of the participants on the operated and non-operated sides was evaluated with five different SLHTs. The SLHT included the single hop for distance (SH), triple hop for distance (TH), crossover triple hop for distance (CH), medial side triple hop for distance (MSTH), and medial rotation (90°) hop for distance (MRH). Results: There was a significant improvement in the mean Lysholm, Tegner, and IKDC scores in the post-operative leg for both techniques (p < 0.05) compared to the pre-operative levels. When there was a difference between the SH of the operative and the non-operative legs in the ST/G technique (p < 0.05), there was no significant difference in the other hop distance for both ST/G and MAI (p > 0.05). There was no difference between the techniques regarding the LSI scores. Conclusions: The fact that our research revealed similar LSI rates of the SLHTs applied in different directions in the ST/G and MAI techniques assumes that the MAI technique can be an ACLR technique which can be functionally used in athletes.

B7-H3: A Useful Emerging Diagnostic Marker for Colon Cancer.

Background: Colon cancer is the second most common malignancy causing the majority of cancer-related deaths. B7-H3 concentrations have drawn major interest as possible diagnostic biomarkers of cancer. The aim of this study was to measure the preoperative serum B7-H3 levels and to determine those that are replaced in colon cancer. Method: We measured preoperative serum B7-H3 concentrations of 90 patients aged 57-69 years diagnosed with colon cancer and 50 age-matched healthy individuals. B7-H3 levels were determined using the sandwich enzyme-linked immunosorbent assay (ELISA). Patients were categorized by stage based on the TNM staging system, and the serum levels of B7-H3 were compared between patients with different TNM stages. Result: No statistically significant difference was found between the patient and control groups in terms of age and gender. Preoperative serum B7-H3 levels were statistically significantly higher in patients with colon cancer than in the healthy group (p < 0.001). Preoperative serum B7-H3 concentration of the stage IV patients was significantly higher than those of the patients with stage I and stage II disease. In addition, higher serum B7-H3 levels were associated with lymph node status and distant metastasis in colon cancer. Conclusion: We showed that B7-H3 is highly expressed in colon cancer and can be used as a candidate diagnostic biomarker and a potential target in colon cancer in future.

Effect of Respiratory Muscle Training on Pitch Range and Sound Duration in Brass Instrument Players and Singers.

OBJECTIVE: Effective use of respiratory organs is important for musicians. Therefore, the impact of Respiratory Muscle Training (RMT) on phonation is open to research. The aim of this study was to investigate the measurable effects of RMT on blowing in brass instrumental and on voice performance in singers. METHODS: Thirty musicians were recruited and separated into a four groups. The brass instrumental and singers groups were further subdivided into control and RMT groups for a 4 week RMT intervention giving a total four groups: singers experimental (SE; n:10), singers control (SC; n:10), brass instrument players experimental (BIPE; n:5), and BIPC (n:5). The groups selected from the musicians of Samsun State Opera and Ballet Directorate and Samsun Metropolitan Municipality Band Team participated in the study. RESULTS: After 4 weeks of RMT application in the study groups, significant increase in all parameters except Forced vital capacity/Forced expiratory volume in 1 second was observed in the values of pulmonary function tests and respiratory muscle strength in subjects with SE and BIPE (P < 0.05). The most significant results of this study are that in addition to changes in the duration of phonation (SE 36%), high-pitch (SE 79%, BIPE 27%) and low-pitch sounds (BIPE 61% and SE 42%), the SE (15%) and BIPE (3%) groups reached higher pitches in the high-pitch notes. CONCLUSIONS: It was determined that performance of the highest and lowest pitch sounds within a vocal register in a single breath and phonation times can be improved by RMT.

Delayed diagnosis and successful management of completely transected common hepatic duct in a blunt multitrauma patient.

Extrahepatic bile duct injuries are very uncommon and easily be missed in multitrauma patients. Patients suffer from bile duct injuries need special approach to this situation. In this report, a case with total transection of common hepatic duct and treatment approach was presented. In unstable patients, damage control surgery can be applied. A 32-year-old male patient was brought to the emergency department after a beating that includes multiple blunt trauma. Radiological screening showed cranial, nasal, lumbar vertebral, and costal bone fractures, decreased blood flow to the right kidney and free perihepatic and perisplenic fluid. Neurosurgeons operated this patient at the day of admission and no plan for laparotomy was made for this patient at that time. Second day postoperatively patient was transferred to the department of surgery and exploratory laparotomy has been made. Common hepatic duct was fully transected and because of the patient's hemodynamic instability, an external fistula has been made. The patient discharged 10th day postoperatively. The patient was operated after follow-up and a Roux-en-y hepaticojejunostomy has been made. Extrahepatic bile duct injuries are rare and high suspicion is important in complex multitrauma patients. Extent of the injury is unique for every patient and technical aspect of repair can be challenging.

Examination of anthropometric characteristics of police academy students / Examen de las características antropométricas de los estudiantes de la academia de policía

SUMMARY: Anthropometric data, which is highly correlated with health and high level of physical capacity, is very important for police officer. The aim of this study was to examine the anthropometric data of police college students and compare in terms of gender. Fifty-two police college students (32 females and 20 males) participated in the present study. Index calculations were made by applying anthropometric test measurements to all participants. The data included anthropometric (length measurements, width measurements, circumference measurement) and index [Body Mass Index (BMI), Cormic Index (C-Index), Body Adiposity Index (BAI), Ponderal Index (PI), Conicity Index (Con-Index) Waist-to-Height Ratio (WHtR)] parameters. The Independent Sample T-Test was used to analyze the difference in groups. A statistically significant difference was found in all parameters except leg length in length measurements (p<0.05). The mean of all width measurements except shoulder width of females was higher than that of male participants. Differences were obtained in all variables except hand and hip-width (p<0.05). In circumference measurements, there was a difference between the groups in the measurement values of the relaxed arm, maximum arm, wrist, shoulder, chest, and hip circumferences (p<0.05). The BAI, PI, WHtR, and Con-Index values were significantly different between groups (p<0.05). In conclusion, the length, width, circumference, and kinanthropometric indexes of male and female police candidates differ. Although male have higher mean values in length and circumference measurements, female have a higher mean for width measurements. Females have higher mean values in general in terms of index values and they are inincreased risk group in terms of WHtR index. It can be recommended for all participants, especially females, to participate in regular physical activity after they start working.

RESUMEN: Los datos antropométricos que están fuertemente correlacionados con la salud y el alto nivel de capacidad física, son muy importantes para el oficial de policía. El objetivo de este estudio fue examinar los datos antropométricos de estudiantes universitarios de policía y compararlos en relación al género. En el estudio participaron 52 estudiantes universitarios de policía (32 mujeres y 20 hombres). Los cálculos de los índices a los participantes se realizaron aplicando mediciones de pruebas antropométricas. Los datos antropométricos incluyeron (medidas de longitud, ancho y circunferencia) además de índice [Índice de masa corporal (IMC), Índice córmico (Índice C), Índice de adiposidad corporal (IAC), Índice ponderal (IP), Índice de conicidad (Con-Índice) y Relación cintura-altura (WHtR)]. Se utilizó la prueba T para muestras independientes para analizar la diferencia entre los grupos. Se encontró una diferencia estadísticamente significativa en todos los parámetros excepto en la longitud de las piernas (p<0,05). La media de todas las medidas de ancho excepto el ancho de los hombros de las mujeres fue mayor que la de los hombres. Se obtuvieron diferencias en todas las variables excepto en el ancho de manos y caderas (p<0,05). En las medidas de circunferencia, hubo diferencia entre los grupos en el brazo relajado, brazo máximo, muñeca, hombro, pecho y cadera (p<0,05). Los valores de BAI, IPI, WHtR y Con-Index fueron significativamente diferentes entre los grupos (p<0,05). En conclusión, los índices de largo, ancho, circunferencia y cineantropométricos de los candidatos a policías difieren entre hombres y mujeres. Aunque los hombres tienen valores medios más altos en las medidas de longitud y circunferencia, las mujeres tienen una media más alta en las medidas de ancho. Las mujeres tienen valores medios más altos en general, en términos de valores de índice, y se encuentran en un grupo de mayor riesgo en términos de índice WHtR. Se puede recomendar a todos los candidatos y candidatas a policía, especialmente a las mujeres, que participen en actividades físicas regularmente después de comenzar a trabajar.

Ultrasound assessment of diaphragm thickness in athletes / Evaluación por ultrasonido del grosor del diafragma en atletas

SUMMARY: The main purpose of this study was to examine the correlation between the aerobic and anaerobic performance of diaphragm thickness in athletes. That study was conducted with 15 team athletes (TA) (age 21.80 ± 2.40 years), 15 individual athletes (IA) (age 18.93 ± 2.31 years) and the control group (CON) 10 people living sedentary lifestyles (age 23.60 ± 2.91 years). In this study, diaphragm muscle thickness (B-mode ultrasonography), respiratory function (spirometry and maximum inspiratory (MIP) and expiratory pressures (MEP), aerobic capacity yo-yo intermittent endurance Test 1 (YYIET-1), and anaerobic power by Monark 834 E were assessed. The diaphragm thickness was determined from the intercostalspace between the 8th and 9th ribs at the expiration time by ultrasound and from the intercostal space between the 10th and 11th ribs at inspiration and then, the thickness of the diaphragm was measured from the diaphragm is seen best. There was a positive correlation between DiTins (r= 0.477) and DiTins-ex (r= 0.473) parameters of TA. In IA, there was a significant correlation between DiTins and DiTins-ex parameters and Peak Power (r= 0.495 and 0.435, respectively) and average power (r= 0.483 and 0.446, respectively). No significant correlation in all parameters of the CON group (p<0.05). As a result, it was determined that athletes with high diaphragm thickness had higher anaerobic performance, and athletes with thinner diaphragm thickness had better VO2Max capacity. The diaphragm thickness of the athletes in individual branches was thicker than the team athletes, and their anaerobic performance was also higher.

RESUMEN: El objetivo principal de este estudio fue examinar la correlación entre el rendimiento aeróbico y anaeróbico del grosor del diaframa en atletas. Dicho estudio se realizó con 15 deportistas de equipo (TA) (edad 21,80 ± 2,40 años), 15 deportistas individuales (IA) (edad 18,93 ± 2,31 años) y el grupo control (CON) 10 personas con sedentarismo (edad 23,60 ± 2,91 años). Se midió, el grosor del diaframa (ultrasonografía en modo B), la función respiratoria (espirometría y presiones máximas inspiratorias (MIP) y espiratorias (MEP), prueba de resistencia intermitente yo- yo de capacidad aeróbica 1 (YYIET-1) y resistencia anaeróbica potencia por Monark 834 E. El grosor del diafragma se determinó a partir del espacio intercostal entre las costillas 8 y 9 en el momento de la espiración por ultrasonido y del espacio intercostal entre las costillas 10 y 11 en la inspiración. Hubo una correlación positiva entre los parámetros DiT ins (r= 0,477) y DiTins-ex (r= 0,473) de TA. En IA, hubo una correlación significativa entre los parámetros DiTins y DiTins-ex y el pico Potencia (r= 0,495 y 0,435, respectivamente) y potencia media (r= 0,483 y 0,446, respectivamente). No hubo correlación significativa en todos los parámetros del grupo CON (p<0,05). Como resultado, se determinó que los atletas con mayor espesor del diaframa tenían un mayor rendimiento anaeróbico, y los atletas con menor espesor del diaframa tenían una mejor capacidad de VO2Max. El grosor del diafragma de los atletas en ramas individuales fue mayor que el de los atletas de equipo, y su rendimiento anaeróbico también fue mayor.

Xanthogranulomatous Cholecystitis: Is Surgery Difficult? Is Laparoscopic Surgery Recommended?

Introduction: Xanthogranulomatous cholecystitis (XGC) is a rare inflammatory disease of the gallbladder (GB). XGC surgery is a difficult process due to its clinical, radiological, and intraoperative findings. In this study, our aim is to show the difficulties of XGC surgery and to find out if laparoscopic surgery is a sufficient procedure. Materials and Methods: Histological findings of 3339 cholecystectomy patients, who were operated between January 2015 and January 2020, were retrospectively reviewed. Age, gender, radiological results, clinical features, intraoperative findings, and surgical management of the patients with XGC were recorded. Results: XGC was observed in 70 patients (2.09%). The average age was 53.75. M:F ratio was 1.2. In radiological examinations, gallstones were found in 94.2% of the patients and GB wall thickness (≥3 mm) was increased in 58.5% of the patients. Around 45.7% of the patients came to the clinic with chronic cholecystitis and 32.9% with acute cholecystitis. In the intraoperative period, adhesions were observed in 80% and increase in GB wall thickness was observed in 77.1% of the patients. The operation started laparoscopically in 66 patients. In 14 patients (21.2%), it was converted to open surgery usually due to insufficient dissection of Calot's triangle. Gallbladder carcinoma (GBC) was suspected in 6 patients, but none of them had malignancy in frozen sections or histology. Conclusions: XGC surgery is difficult due to its radiological, clinical, and intraoperative features and mimicking GBC. It can be converted to open cholecystectomy due to difficulties in laparoscopic dissection. However, since conversion cholecystectomy rates are reasonable, laparoscopic surgery is recommended in patients with suspected XGC.

Esophagoduodenoscopy or colonoscopy: which should be done first?

OBJECTIVES: Esophagoduodenoscopy and colonoscopy can be done as bidirectional endoscopy in the same session. The aim of this study was to compare anesthetic requirements and hemodynamic effects in esophagoduodenoscopy or colonoscopy done first for bidirectional endoscopy. MATERIAL AND METHODS: Eighty patients, aged 18-70 years with an American Society of Anesthesiologists Classification (ASA) as I-III, were included randomly into this study. The patients were allocated into two groups: Group C: first colonoscopy followed by esophagoduodenoscopy. Group E: first esophagoduodenoscopy followed by colonoscopy. All patients received standard anesthesia with 1 µg/kg fentanyl and 1 mg/kg propofol. Demographical variables, Heart rate SpO2, Ramsey Sedation Score were recorded every 10 minutes. Total propofol consumption, retching during esophagoduodenoscopy and time to reach cecum were also recorded. Endoscopist and patient satisfaction were questioned. RESULTS: Retching during esophagoduodenoscopy was not statistically significantly different in both groups. Total procedure duration and esophagoduodenoscopy duration were statistically significant longer in Group E. Complication frequency was higher in Group E. Endoscopist and patient satisfaction were lower in Group E. There was no difference in time to reach the cecum and the recovering period. Additional propofol dose was increased in Group E. CONCLUSION: Regarding shorter procedural duration, lower consumption amount of propofol and fewer complications, it could be a better choice to start bidirectional procedure with colonoscopy first.

Early Surgical Repair of Bile Duct Injuries following Laparoscopic Cholecystectomy: The Sooner the Better.

Background We aimed to investigate the outcomes of the immediate surgical repair of bile duct injuries (BDIs) following laparoscopic cholecystectomy. Materials and Methods Between January 2012 and May 2017, patients, who underwent immediate surgical repair (within 72 hours) for postcholecystectomy BDI, by the same surgical team expert in hepatobiliary surgery, were enrolled into the study. Data collection included demographics, type of BDI according to the Strasberg classification, time to diagnosis, surgical procedures, and outcome. Results There were 13 patients with a mean age of 43 ± 12 years. Classification of BDIs were as follows: type E in six patients (46%), type D in three patients (23%), type C in two (15%), and types B and A in one patient each (7.6%). Mean time to diagnosis was 22 ± 15 hours. Surgical procedures included Roux-en-Y hepaticojejunostomy for all six patients with type-E injury, primary repair of common bile duct for three patients with type-D injury, and primary suturing of the fistula orifice was performed in two cases with type-C injury. Other two patients with type-B and -A injury underwent removal of clips which were placed on common bile duct during index operation and replacing of clips on cystic duct where stump bile leakage was observed probably due to dislodging of clips, respectively. Mean hospital stay was 6.6 ± 3 days. Morbidity with a rate of 30% ( n = 4) was observed during a median follow-up period of 35 months (range: 6-56 months). Mortality was nil. Conclusion Immediate surgical repair of postcholecystectomy BDIs in selected patients leads to promising outcome.

Bilateral and ipsilateral peak torque of quadriceps and hamstring muscles in elite judokas.

OBJECTIVE: To examine bilateral and ipsilateral peak torque values of quadriceps (Q) and hamstring (H) muscles in elite judokas. METHODS: 16 elite male judokas were tested in concentric isokinetic strength of the quadriceps (Q) and hamstrings (H) muscles at 60° and 180° sec-1. Variables comprised average peak torque and the traditional H/Q, Q/Q, H/H ratios. Asymmetries between legs and differences between isokinetic muscle strength ratios were examined using paired t-tests and Cohen's d. RESULTS: In right (Rs) and left (Ls) extremity peak torque values, no significant difference was found between 60° and 180° sec-1 angular velocities (p>0.05). In peak torque values between PLs and NPLs, significant difference was found only in extension (Ex) phase at 60° sec-1 angular velocity p=0.001). (Significance was identified between (Q/Q) and (H/H) muscle ratios at 60° sec-1 (p=0.029). No significant difference was found in ipsilateral strength ratios at 60° and 180° sec-1 angular velocity (p>0.05). CONCLUSIONS: The Ex knee strength of PLs was high, particularly at low angular velocities, leading to differences of bilateral asymmetry in the Q muscle group. Regarding ipsilateral strength ratios, there were no differences in the H and Q muscle groups at both angular velocities, indicating that both legs were similar in terms of ipsilateral asymmetry.

How does the extent of antral resection affect the residual gastric volume and excessive weight loss?

AIM: To identify the effect of the extent of antral resection on the residual gastric volume (RdGV) and excess weight loss (EWL) among patients who underwent laparoscopic sleeve gastrectomy(LSG) due to the obesity. MATERIAL AND METHODS: The demographical data, operative details, postoperative morbidity, mortality and the percentages of EWL in the postoperative 3, 6 and 12 months of the patients who underwent LSG between January 2014 and August 2015 were analyzed. These patients were divided into three groups regarding the antral resection margin (ARM): Group 1(n=80): ARM≤3cm; Group2 (n=35): 3 6cm from pylorus) resulted in reduced operating cost and decelerated reach to optimal EWL% with similar postoperative outcomes. KEY WORDS: Antral resection margin, Excess weight loss, Laparoscopic sleeve gastrectomy, Residual gastric volume, Surgical technique.

Inspiratory muscle training improves pulmonary functions and respiratory muscle strength in healthy male smokers.

The aim of the present study is to investigate the effects of inspiratory muscle training (IMT) on pulmonary function and respiratory muscle strength of both healthy smokers and nonsmokers. Forty-two healthy males (16 in the IMT smokers group [IMTS], 16 in the IMT nonsmokers group [IMTN], and 10 in the placebo group) participated in the present study. Using a randomized, double-blind, placebo-controlled design, IMTS and IMTN underwent 4 weeks of 30 breaths twice daily at 50% (+5% increase each week) of maximum inspiratory pressure (MIP), while the placebo group maintained 30 breaths twice daily at 15% MIP using an IMT device. The data were analyzed with repeated measures for one-way analysis of variance, 3 × 2 mixed factor analysis of variance, and least significant difference tests. Respiratory muscle strength (MIP and maximal expiratory pressure [MEP]) and pulmonary functions significantly improved after a 4-week period (between the pre and posttests) in the IMTN and IMTS groups (p < 0.05). The mean difference and percentage differences showed significant alterations in the respiratory muscle strength, forced and slow pulmonary capacities, and pulmonary volume between the IMTN and IMTS groups (p < 0.05). There were significant changes in the expiratory muscle strength (MEP), slow vital capacity (SVC), and forced pulmonary measurements (forced expiratory volume after 1 s and maximal voluntary ventilation) between IMTN and IMTS groups in favor of smokers (p < 0.05). These results show that greater improvements occurred in smokers after IMT. Increased respiratory muscle strength may be the underlying mechanism responsible for this improvement. Additionally, the benefits of IMT were greater in smokers than nonsmokers. This difference between smokers and nonsmokers may potentially be explained by higher influence of exercise on smokers' lung microbiome, resulting in greater reversal of negative effects.

Is it Necessary to Measure Blood Glucose Level Before and After Colonoscopy in Diabetic and Nondiabetic Patients?

OBJECTIVES: The aim of this study was to examine the necessity of measuring the blood glucose level before and after a colonoscopy in diabetic and nondiabetic patients. METHODS: A total of 200 patients who were over the age of 18 with an American Society of Anesthesiologists (ASA) score I-IV and were to undergo an elective colonoscopy procedure were included in this randomized, controlled, prospective trial. In the study group, 100 patients were diabetic and 100 were nondiabetic. Patient age, sex, body mass index, ASA classification, comorbid diseases, daily medications, and the length of preprocedure fasting were recorded. Before the procedure, the capillary glucose level was measured and recorded as an initial value. This glucose assessment was repeated and recorded 15 minutes after the beginning of the colonoscopy and 60 minutes after the procedure. All complications related to the anesthesia or the colonoscopy were recorded. RESULTS: The sex and age distribution was not statistically significant in a comparison of the diabetic and nondiabetic groups. The body mass index value and presence of comorbid diseases, particularly hypertension, was statistically significantly higher in the diabetic group. There was no significant difference in complications between the groups. The mean fasting time in the diabetic group was statistically significantly shorter than that of the nondiabetics. The blood glucose level of the diabetic patients was consistently higher than that of the nondiabetics. CONCLUSION: Blood glucose measurement is necessary for diabetic patients before and after a colonoscopy procedure; however, assessment is not necessary for nondiabetics.
