Can delta neutrophil index values predict the success of periodontal treatment in patients with periodontitis?

OBJECTIVES: The aim of this study was to evaluate the effect of delta neutrophil index (DNI) on non-surgical periodontal therapy (NSPT), whose role has been documented in the pathogenesis and follow-up of periodontal disease. METHODS AND MATERIALS: The study included 35 patients with stage 3, grade A periodontitis (test group) and 35 patients without periodontal disease (control group). Initially, periodontal parameters were recorded and blood samples were taken from all patients. For patients with periodontitis, periodontal parameter measurements and blood sample analyses were repeated 3 months after NSPT. RESULTS: After NSPT, DNI, CRP (C-reactive protein), neutrophil count, WBC (white blood cell), and neutrophil-lymphocyte ratio (NLR) values decreased in the test group, but did not reach a statistically significant level (p > 0.05). When the inflammatory variables were examined, significantly higher CRP, IG (immature granulocytes), DNI, neutrophil count, and WBC were observed in the test group compared to the control group (p < 0.05). In the test group, periodontal parameters were lower 3 months after NSPT than at baseline (p < 0.05). CONCLUSION: Consistent with previous findings in the literature, the patients with periodontitis were determined to have higher levels of DNI, CRP, neutrophils, and WBC, compared to the individuals without periodontitis. Although a decrease was seen in DNI after NSPT, this was not at a significant level. CLINICAL RELEVANCE: DNI is a guide in the evaluation of inflammation at the onset of periodontal disease, but studies with a larger number of cases are needed to use these parameters in the evaluation of treatment success. TRIAL REGISTRATION: This study was retrospectively registered on December 27, 2022, with the number NCT05666622 at http://www. CLINICALTRIALS: gov .

Delta Neutrophil Index and Neutrophil-to-Lymphocyte Ratio in the Differentiation of Thyroid Malignancy and Nodular Goiter.

BACKGROUND: It was aimed to evaluate the relationship between delta neutrophil index (DNI) and neutrophil-to-lymphocyte ratio (NLR) in the preoperative differentiation of nodular goiter and thyroid malignancy. METHODS: Patients over the age of 18 who underwent thyroid surgery between November 2014 and November 2019 were evaluated in this retrospective cohort study. Patients were divided into two groups according to their pathology results: malignant (Group M) and benign (Group B) thyroid disorders. White blood cell (WBC) count, neutrophil count, lymphocyte count, IG count and DNI were measured using an automated hematological analyzer from blood samples obtained at the preoperative period and postoperative 6th month of the follow-up. Neutrophil-to-lymphocyte ratio (NLR) values were manually calculated. Numerical data are expressed as means ± standard deviations (minimum-maximum values) or medians (minimum-maximum values) according to the normal distribution. Categorical values are expressed as percentages (%). RESULTS: A total of 243 patients (190 patients in Group B and 53 patients in Group M) who met the inclusion criteria were evaluated. The male/female ratio was 49/194. A statistically significant difference between Group M and Group B in terms of preoperative NLR, DNI and IG count was observed (p = 0.001, < 0.001 and < 0.001, respectively). No statistically significant difference was observed between the groups in terms of the control values performed in the postoperative period in terms of the NLR, DNI and IG count (p = 0.711, 0.333 and 0.714, respectively). A significant decrease was observed in the preoperative and postoperative DNIs, IG counts and NLRs in Group M (p = 0.009, < 0.001 and < 0.001, respectively). For the diagnosis of malignant thyroid diseases, the cut-off value of DNIs was ≥0.35%, and DNI sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were 79.2%, 78.9%, 79.2% and 77.9%, respectively (area under the curve [AUC]: 0.847; confidence interval [CI]: 0.784-0.911). The cut-off value of the IG count was ≥25/mm3, and its sensitivity, specificity, PPV and NPV were 83%, 72.1%, 83%, and 72.1%, respectively (AUC: 0.847; CI: 0.784-0.911). CONCLUSION: DNI and IG counts are cheap and easily accessible tests that can be automatically calculated from automated systems without additional cost in differentiation of thyroid malignancies from benign disorders in the preoperative period.

Effects of vascular morphological features and ultrasound-guided vascular cannulation techniques on the success of femoral artery catheterisation in newborns.

Ultrasound-guided vascular access is a technique that can increase safety as well as technical and procedural success when performing invasive cardiovascular procedures. The aim of this study was to evaluate the effects of two cannulation techniques and vascular morphological properties on the success of femoral artery catheterisation in neonatal patients. We recruited 65 consecutive patients requiring femoral artery catheterisation and randomly divided them into two groups: Group 1, in-plane technique (n = 31) and Group 2, out-of-plane technique (n = 34). We compared the preparation duration, puncture duration, number of punctures, number of arterial punctures, number of unsuccessful interventions, hematoma incidence and vascular morphological characteristics between the groups. The mean age of Group 1 was 17.16 ± 7.04 days, and the mean age of Group 2 was 17.20 ± 7.40 days, with no difference observed between the groups (p > 0.05). Four patients in Group 1 and nine patients in Group 2 developed hematoma (p = 0.172). Hematoma was strongly correlated with the number of venous punctures (r = 0.632; p = 0.001) and the number of needle advancements (r = 0.415; p = 0.001). In terms of artery-vein position, patients whose artery overlapped the vein by > 50% required clearly longer artery cannulation durations than the other patients (p < 0.001). Although the in-plane technique has a steep learning curve, it was found superior in terms of procedure-related factors such as the number of trials, the incidence of hematoma and arterial puncture counts, as it offers advantages such as the ability to evaluate the lumen and a better control of the needle advancement direction.

Assessment of Somatic Support Process for Pregnant Brain Death Patients Occurring in a Transition Country Between Asia and Europe from Medical, Ethical, Legal and Religious Aspects.

In spite of the fact that brain death during pregnancy is not a common occurrence, it is an important ethical problem for all cultures and religions can have a significant influence on the donation decision after brain death. Therefore, this study aimed to present the case of a pregnant patient developing brain death which occurred in our intensive care unit and to compare the medical, ethical and legal problems relating to pregnant cases developing brain death with 24 cases in the literature. A 21-year-old 19-week pregnant case with gestational diabetes was monitored in the anesthesia intensive care unit and developed brain death due to intracranial mass and intraventricular hemorrhage. Though brain death is a situation well understood by organ transplant professionals, brain death developing in pregnant patients still involves many medical, ethical and legal problems.

Use of Silver Nitrate Application as Mini-Invasive Treatment of Pilonidal Sinus Disease.

OBJECTIVES: To investigate the cure rate and adverse effects of silver nitrate application for treatment of pilonidal sinus disease (PSD). Methods: Number of sinus pit orifices, and complications with silver nitrate application and debridement for sacrococcygeal PSD between January 2015 and July 2018 were analyzed in this retrospective study. Data were obtained from surgical, discharge, and outpatient follow-up records. Among 56 patients who were treated with silver nitrate stick, 11 patients with incomplete hospital records were excluded from the study. Demographic data including age, gender, length of follow-up, number of silver nitrate applications, number of involved sinuses and recurrence and complication rates were recorded. Results were expressed as frequencies, means, and range of values. The Mann Whitney U and chi square tests were used to evaluate significance. Results: Mean age was 24.3 +- 5.18 (range, 14 - 36) years, and recurrence occurred in 4 (8.9%) patients. Complications developed in 10 (22.2%) patients and included abscess, erythema, and necrosis in 5 (11.1%), 2 (4.4%), and 3 (6.6%) patients, respectively. The recurrence rate was significantly higher in patients who developed abscesses during the follow-up period (p = 0.001) than those who did not. There was no statistically significant correlation between the recurrence rate and number of sinuses or the number of silver nitrate applications. CONCLUSION: Low morbidity and high healing rates achieved with silver nitrate provide support for this application as a feasible and effective conservative outpatient treatment for PSD in certain patients.

The value of ischemia-modified albumin and oxidative stress markers in the diagnosis of acute appendicitis in adults.

INTRODUCTION: The present study evaluates the predictive value of such markers as ischemia-modified albumin (IMA), malondialdehyde (MDA) and glutathione peroxide (GSH-Px), in addition to parameters associated with inflammation, oxidative stress and ischemia, playing roles in the pathology of acute appendicitis (AA), including c-reactive protein (CRP), procalcitonin (PCT) and complete blood count (CBC) parameters and their ratios, for the diagnosis of AA in adults. MATERIAL AND METHODS: The study included 51 patients with histologically confirmed appendicitis and 45 healthy controls who referred to the emergency care unit between January and June 2018. The appendicitis cases were classified into two groups, as complicated and non-complicated, based on postoperative pathological investigations. RESULTS: Of all the appendicitis cases, 68.5% (n = 35) were non-complicated and 31.4% (n = 16) were complicated. IMA (positive LR = 3.0, negative LR = 0.1), GSH-Px (positive LR = 0.5, negative LR = 1.8), MDA (positive LR = 1.8, negative LR = 0.6), CRP (positive LR = 7.2, negative LR = 0.2), PCT (positive LR = 0.7, negative LR = 1.3), WBC (positive LR = 2.9, negative LR = 0.3), neutrophil-lymphocyte ratio (positive LR = 3.2, negative LR = 0.1) thrombocyte lymphocyte ratio (positive LR = 1.6, negative LR = 0.5) and IMA/albumin ratio (positive LR = 3.3, negative LR = 0.1) levels in the appendicitis cases were evaluated by a characteristic receiver operating characteristic (ROC) curve. In addition, IMA levels were significantly higher in the complicated cases (0.40 ±â€¯0.05 AbsU) than in the non-complicated cases (0.29 ±â€¯0.04 AbsU) (p < 0.0001). CONCLUSION: Our results showed that IMA (negative LR = 0.1), CRP (positive LR = 7.2, negative LR = 0.2), NLR (negative LR = 0.1) and IMA/albumin ratio (negative LR = 0.1) can serve as important diagnostic biomarkers for AA patients. We therefore believe that before clinically confirming an AA diagnosis, these parameters may be used as diagnostic tools in addition to CBC parameters, CRP levels and radiological imaging studies.

The Preseptic Period and Inflammatory Markers in the Prediction of the Course of Sepsis.

BACKGROUND The aim of this study was to find a simple and easily accessible scoring system that could predict the development of sepsis in the preseptic period. MATERIAL AND METHODS The study included 161 patients with a basal sequential organ failure assessment (SOFA) value of 2 or more. The sepsis group (n=83) comprised patients with infection reported in culture results; the control group (n=78) comprised patients not showing evidence of infection in blood, urine, and phlegm cultures; samples were taken on three consecutive days. RESULTS The patients in both groups were divided into subgroups of non-survivor and survivor patients. The preseptic and septic SOFA score, neutrophil lymphocyte ratio (NLR), and procalcitonin (PRC) and lactate (Lac) values were determined to be statistically significantly higher in the sepsis group than in the control group. When the values related to sepsis were examined, a strong relationship was determined between sepsis and SOFA score, PRC values, and Lac values in the preseptic period and a weak relationship with NLR. In the model formed using multiple regression analysis with defined cutoff values for the preseptic and the septic periods, we found that in the septic period, a diagnosis of sepsis could be made with 83.8% accuracy. The diagnostic value of the same parameters evaluated in the preseptic period was 77.9%. CONCLUSIONS The diagnostic value of the combination of Lac, PRC, SOFA, and NLR were found to be similar in the preseptic period as the sepsis period; thus these combined values could safely be used for the early diagnosis of sepsis.

Effects on QTc Interval of 2 Different Doses of Spinal Anesthesia in Inguinal Hernia Operations.

BACKGROUND Cardiac arrhythmia is a significant cause of morbidity and mortality. In this study, through examination of the effects on the QTc interval of different doses of hyperbaric bupivacaine, we investigated the relationship with arrhythmia. MATERIAL AND METHODS A total of 60 patients were separated into 2 groups: spinal block was applied with 10 mg bupivacaine to Group S1 and with 15 mg to Group S2. The mean arterial pressure (MAP) and heart rate (HR) values were recorded before the spinal block and at 5 and 30 min after the block and at 60 min postoperatively. By recording the time of the spinal sensory block to reach T10 dermatome (Anaesth T) and the duration of the surgical procedure (Surg T.), the QTc intervals were calculated. RESULTS The demographic data were similar in both groups. A statistically significant difference was determined between the S1 and S2 groups between the baseline and the 30 mins after spinal block QTc intervals (p=0.001). No statistically significant difference in HR values was determined between the groups at baseline, 5 min after spinal block, and 1 h after surgery (all p>0.05), but at 30 min after spinal block value there was a statistically significant difference (p=0.010). No statistically significant difference was determined in MAP values between the groups at baseline and 1 h after surgery (p>0.05). CONCLUSIONS The QTc interval lengthened in a dose-dependent manner after spinal anesthesia was applied with different doses of bupivacaine, but the doses used did not cause any severe arrhythmia.

An obstruction not to forget: Pseudo-obstruction (Ogilvie syndrome): Single center experience.

PURPOSE: Colonic pseudo obstruction disease commonly seen in the elderly, immobile patient group can cause serious mortality and morbidity. Our objective in this retrospective study is to share our clinical experience by evaluating patients with Ogilvie syndrome who were followed and treated in our clinic. METHODS: Eleven cases with the diagnosis of Ogilvie syndrome followed up and treated between September 2010 and April 2013 were evaluated retrospectively. All the patients that had no symptoms of acute abdominal pain were initiated conservative treatment. Colonoscopic decompression was attempted for patients whose clinical pictures were not recovered. Patients underwent operation if they developed peritoneal irritation symptoms during these procedures and of their number of white blood cells seriously increased during the follow-up period. RESULTS: A total of 11 patients were treated for Ogilvie syndrome. 6 of the patients underwent surgical treatment, and 5 were treated medically. Mortality developed in two patients. The main cause of mortality was a delay in diagnosis and additional severe underlying diseases. Seven patients were given Neostigmine. Of these, 2 patients required surgery and 3 patients responded to Neostigmine. CONCLUSION: Ogilvie syndrome is a rare cause of ileus of the colon. It is more common particularly in old patients with additional problems. If the disease is suspected and diagnosed early, unnecessary surgical interventions can be prevented with medical treatment choices.

The efficacy of fibrin glue to control hemorrhage from the gallbladder bed during laparoscopic cholecystectomy.

OBJECTIVE: The aim of the study is to report our experience with fibrin glue application in the management of bleeding from the gallbladder bed during laparoscopic cholecystectomy, which could not be controlled by conventional methods. MATERIAL AND METHODS: Three hundred eighty-two patients underwent laparoscopic cholecystectomy. Fourteen patients with bleeding from the gallbladder bed, which could not be controlled by conventional methods, were analyzed retrospectively. RESULTS: Fibrin glue was used in 10 patients. Six (71%) were female and 4 were (29%) male. The mean age was 55.7 years. Fourteen patients were operated for the presence of symptomatic gallstones. Thirteen patients (92%) had a concomitant pathology. The mean time spent to maintain hemostasis was 23.9 minutes (15-35). Blood products were used in two patients with hemoglobin values under 8 mg/dL. Hemostasis could not be achieved in a patient despite fibrin glue application, and the operation was converted to open surgery. CONCLUSION: The application of fibrin glue for bleeding from the gallbladder bed during laparoscopic cholecystectomy can reduce conversion rates, further studies including more patients are required.

The effect of transversus abdominis plane block application on postoperative analgesia quality and patient satisfaction after varicocele surgery: a randomized clinical trial.

Background: Postoperative pain management is an important aspect of anesthesia care and multimodal analgesic techniques are generally recommended. Objective: To compare the effect of spinal anesthesia + transversus abdominis plane (TAP) block application on postoperative analgesia quality and patient satisfaction with spinal anesthesia + intrathecal morphine (ITM) application. Methods: A total of 70 patients were randomly separated into 2 groups as spinal anesthesia + TAP block (TAP block group, n = 34) and spinal anesthesia + ITM group (ITM group, n = 36). The groups were compared in respect of age, body mass index values, and visual analog scale (VAS) values at 0 h, 2 h, 6 h, 12 h, and 18 h, and patient satisfaction was scored by Quality Improvement in Postoperative Pain Management at 24 h. Results: The mean age of the patients was 32.52 ± 6.50 years in the TAP block group and 30.11 ± 5.62 years in the ITM group, with no statistically significant difference determined. There was no statistically significant difference in terms of VAS values at 0 h, 2 h, 6 h, 12 h, and 18 h. When the factors affecting postoperative patient satisfaction were evaluated, feeling fatigue after the surgery (r = -0.811, P = 0.001) and postoperative complications such as nausea, vomiting, and itching (r = -0.831, P = 0.001) were found to have a negative effect on patient satisfaction. Conclusion: Due to low complication rates, TAP block is an effective application for postoperative analgesia management in varicocele operations that increases patient satisfaction postoperatively.

Are the immature granulocyte count and percentage important in continue medical treatment in acute appendicitis? A prospective, randomized, and controlled study.

BACKGROUND: Although appendectomy is still a curative therapy for acute appendicitis, medical treatment has come to the fore in uncomplicated cases. This study aimed to determine the importance of immature granulocyte (IG) count and percentage for the role of medical treatment success in uncomplicated acute appendicitis. METHODS: Acute appendicitis cases were prospectively registered between July 2019 and April 2020. Using ball drawing, patients were divided into two groups as medical treatment (Group M) and undergo appendectomy (Group A). Group M was divided into two subgroups as those who responded to medical treatment medically responded (MR) and failed medical treatment (MF) within 24 h of follow-up. Changes in IG count and percentage, C-reactive protein levels, neutrophil-lymphocyte ratio, and white blood cell count between initial administration and 24th h of follow-up were examined. RESULTS: Sixty-four patients who met the inclusion criteria were followed as 31 patients in Group A and 33 in Group M. At Sub-group MF 11 patients and Subgroup MR 22 patients were followed up. At the 24th h of the follow-up, the IG count and percentage were higher in the Group MF (for IG count: Between Group A and MF, p=0.002; between Group A and Group MR, p=0.111; and between Group MR and MF, p<0.001) (for IG percentage: Between Group A and MF, p=0.001; between Group A and MR, p=0.809; and between Group MF and MR, p=0.001). This decrease in the IG count and percentage suggests that the response to medical treatment was effective [for IG count: F (148.862) = 61, p≤0.001, η2=0.707] [for IG percentage: F (10.157) = 0.252, p≤0.001, η2=0.504]. CONCLUSION: IG count and percentage are effective for evaluating the success of medical treatment of uncomplicated acute ap-pendicitis and they guide in the decision to continue medical treatment of uncomplicated acute appendicitis.

Immature Granulocyte Count and Delta Neutrophil Index as New Predictive Factors for Axillary Metastasis of Breast Cancer.

OBJECTIVE: To determine the diagnostic value of preoperative immature granulocyte (IG) count and delta neutrophil index (DNI) level before clinical detection of axillary lymph node metastasis. STUDY DESIGN: Cohort study. PLACE AND DURATION OF STUDY: Department of General Surgery, Kahramanmaras Sutcu Imam University, Onikisubat, Turkey from February 2015 to February 2020. METHODOLOGY: Patients older than 18 years and operated for breast pathologies in the study period were evaluated retrospectively. Patients without axillary or distant organ metastasis, and who did not receive neoadjuvant chemotherapy were examined by dividing them into two groups as pathologically non-metastatic axilla (Group NM) and metastatic axilla (Group M). They were retrospectively evaluated for DNI, IG, white blood cell count (WBC), neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR) and mean platelet volumes (MPV). RESULTS: All of the 83 patients, who met the inclusion criteria, were females (100%). Forty-six patients (55.42%) were in the Group-NM and 37 (44.58%) were in Group-M. Statistically significant difference was observed between the groups in terms of WBC, NLR, PLR, MPV, DNI and IG count (p<0.05), while there was no difference in age (p = 0.862). As a result of the univariate and multivariate analysis, WBC, NLR, PLR, MPV, DNI and IG count were determined as predictive factors. The discriminatory power of the DNI for diagnosing clinically negative pathologically positive axillary metastasis of breast cancer at the cut-off value ≥0.35% (ARUC:0.903; 95% confidence interval [CI]: 0.84-0.967) showed 86.5% sensitivity, 80.4% specificity, positive predictive value (PPV) 86.5%, negative predictive value (NPV) 80.4%. The discriminatory power of the IG count for diagnosing clinically negative pathologically positive axillary metastasis of breast cancer, at the cut-off value ≥25/mm3 (ARUC:0.976; 95% CI:0.953-1.000) showed 100% sensitivity, 82.6% specificity, 100% PPV, and 82.6% NPV. CONCLUSION: DNI and IG count may be new predictive factors with high sensitivity and specificity in detecting axillary metastasis of breast cancer. Key Words: Delta neutrophil index, Immature granulocyte count, Neutrophil lymphocyte ratio, Breast cancer, Axillary metastasis.

An examination by year of cases applied with caesarean hysterectomy because of placenta percreta in a tertiary centre: a retrospective cohort study.

OBJECTIVES: To examine cases applied with caesarean hysterectomy because of placenta percreta by comparing changes in treatment strategies and complications according to year. MATERIAL AND METHODS: A retrospective examination was made of 93 patients applied with caesarean hysterectomy with a diagnosis of placenta percreta in 5-year periods of 2005-2009, 2010-2014, and 2015-2019. Demographic characteristics were recorded, and previous caesareans, history of myomectomy and curettage, gestational weeks, and infant birthweight. Intraoperative and postoperative findings were recorded as operating time, length of stay in hospital and Intensive Care Unit (ICU), transfusion requirement, the amount of erythrocyte suspension (ES) and fresh frozen plasma (FFP) transfused, and requirement for massive transfusion. Anaesthesia type, complications, and the preferred skin-uterus incision were also recorded. RESULTS: The 93 patients comprised 8 cases in the period 2005-2009, 23 in 2010-2014, and 62 in 2015-2019. The number of previous caesarean procedures was observed to increase in parallel with these case numbers. A significant increase was observed in the gestational week of birth, and infant birthweight, and a decrease in operating times. In later years there was seen to be a lower amount of ES and FFP transfused and fewer patients with massive transfusion. Preoperative diagnosis of placenta percreta, the highest preference for general anaesthesia, selection of midline vertical skin incision and uterine fundal incision were greatest in the period 2015-2019. CONCLUSIONS: In cases with placenta percreta, of which there is an increasing incidence, maternal and infant outcomes can be optimised with prenatal diagnosis and planned caesarean hysterectomy by a multidisciplinary team with optimal prenatal preparation.

A Diagnostic Dilemma for Acute Abdomen: Sclerosing Encapsulating Peritonitis (Abdominal Cocoon Syndrome); A Retrospective Cohort Study.

BACKGROUND: Sclerosing encapsulating peritonitis (SEP) is a rare cause of acute abdomen and can be easily misdiagnosed. Preoperative diagnosis of the SEP can be performed with preoperative imaging studies. We aimed to evaluate the clinical features of ileus cases who were diagnosed with primary or secondary SEP in the last five years. METHODS: This retrospective cohort study evaluated the patients who were admitted with ileus or acute abdomen symptoms to the Emergency Department of Elazig Training and Research Hospital and underwent surgery by the same surgical team of General Surgery Department between January 2014 and January 2019. Patients who were diagnosed with primary or secondary SEP were included. The demographic data, clinical presentation, whether the disease was primary or secondary, the treatment options performed and mortality rates were evaluated. RESULTS: SEP was observed in 11 of the patients. Ten patients underwent surgery (90.9%), and one patient (9.1%) was treated conservatively. Of the patients, six had secondary SEP (54.5%) and five had primary SEP (45.5%). In total, five patients were female (45.5%) and six were male (54.5%). The median age of the patients was 35 years (24-69). The median age of the patients with primary disease was 48 (29-69) years, while the median age of patients with secondary disease was 34.5 (24-64) years. One patient expired in the postoperative 8th hour. CONCLUSION: SEP should be considered in the case of recurrent abdominal pain attacks, especially in patients undergoing peritoneal dialysis, and it should be known that the mortality rate is high when misdiagnosed.

The efficacy of LigaSure™ open instruments in cases of cesarean hysterectomy due to placenta percreta: a retrospective, record-based, comparative study.

OBJECTIVE: The standard treatment for patients with placenta percreta is cesarean hysterectomy that can cause severe bleeding. New-generation vessel sealing systems like LigaSure can cut and seal vascular structures and tissues. The aim of this study was to retrospectively compare hysterectomies performed with traditional instruments and those performed with LigaSure instruments to determine the possible advantages with the latter. MATERIALS AND METHODS: Patients with placenta percreta who underwent elective cesarean hysterectomy by the same surgeon were divided into two groups based on the type of instruments used. Group 1, the standard conventional hysterectomy group, operated with conventional instruments for cutting and tying; and Group 2, the LigaSure hysterectomy group, operated with the new-generation bipolar sealing and cutting instruments. The groups were retrospectively compared for bleeding, operating time, and complications. RESULTS: In Group 2, the operating time, intraoperative and total transfused erythrocyte suspension units, total fluid in the drain, and total hospital stay were lower than in Group 1 (p < .05), as was the need for internal iliac artery ligation (p = .013). The complication rates were similar between the two groups (p > .05). CONCLUSION: The use of LigaSure open instruments in cesarean hysterectomies in patients with placenta percreta may reduce operating times and the amount of bleeding.

Comparison of the efficacy of surgical tracheostomy and percutaneous dilatational tracheostomy with flexible lightwand and ultrasonography in geriatric intensive care patients.

AIM: To compare the applicability, technical difficulties and postoperative complications of surgical tracheostomy and percutaneous dilatational tracheostomy with the flexible lightwand + ultrasonography method applied because of prolonged intubation to geriatric patients in the intensive care unit. METHODS: A retrospective evaluation was made of 76 patients who received surgical tracheostomy (group 1) and 78 patients who received percutaneous dilatational tracheostomy (group 2). The patients were evaluated in respect of demographic data, duration of intubation, length of stay in the intensive care unit and discharge status, and after the intervention, the development of tube-related complications, early stage local complications and late-stage complications. RESULTS: The time from intubation to tracheostomy was determined as 22.73 ± 15.23 days in group 1 and 12.65 ± 7.64 days in group 2. The mortality rate of patients in group 1 was determined to be statistically significantly higher than that of group 2 (P = 0.048). When evaluated in respect to early and late complications, nine early- and seven late-stage complications developed in group 1, and three early- and three late-stage complications developed in group 2 (P = 0.05). In the evaluation of factors related to mortality, the time from intubation to tracheostomy (r = 0.249, P = 0.01) and the presence of a comorbidity (r = 0.325, P = 0.004) were determined to have a positive correlation with the development of mortality. CONCLUSION: Percutaneous dilatational tracheostomy with the flexible lightwand + ultrasonography technique is a safe, rapid and effective method with the advantage of management in respect to early complications, such as bleeding, and can be used safely in the geriatric patient population in intensive care conditions.

A comparison in an experimental rat model of the effects on adhesion formation of different hemostatic methods used in abdominopelvic surgery.

OBJECTIVES: To evaluate the effects of different hemostasis methods used in abdominal surgery on the development ofabdominal adhesion. MATERIAL AND METHODS: A total of 48 Wistar albino female rats were separated into six groups; Group 1 - Control group,Group 2 - Hemorrhage group, Group 3 - Electrocoautery group, Group 4 - Gel Spon-P®, Group 5 - PAHACEL®, andGroup 6 - Ankaferd-Blood Stopper®. Adhesions that developed were scored according to the Knightly classification andthe prevalence of adhesions according to the Linsky classification. The total adhesion score was calculated as the total ofthe severity and prevalence scores. RESULTS: The lowest total adhesion values were determined in Group 1 (control) and the highest adhesion values were inGroup 2 (hemorrhage) group in terms of all parameters. The adhesion values in Group 3, where the rats were administeredhemostasis with electrocautery were similar to those of Group 2 (hemorrhage). When the alternative methods were evaluated,the lowest adhesion scores were in Group 6 (Ankaferd-Blood Stopper®). CONCLUSIONS: In cases of minor pelvic or abdominal bleeding, not providing hemostasis or applying hemostasis withelectrocautery can increase the development of intra-abdominal adhesions. The use of alternative hemostatic materialsinstead of electrocautery for hemostasis may reduce the formation of adhesions.

The Effect of Flexible Lightwand and Ultrasonography Combination on Complications of the Percutaneous Dilatational Tracheostomy Procedure.

The aim of this study was to evaluate the effect of the flexible lightwand and ultrasonography (USG) combination on reducing the complications in percutaneous dilatational tracheostomy (PDT) opened with the forceps dilatation method. A retrospective examination was made of 138 patients between January 2014 and December 2018. Before starting to process, the anatomic structures of the patients were visualized with USG and the tracheostomy area was marked. Sedation and local anesthesia were applied to patients before the procedure, then the percutaneous tracheostomy was performed using the Griggs technique after confirmation of the tracheostomy localization defined with USG using the transillumination method with a flexible lightwand within an endotracheal tube. Complications that developed associated with the procedure were recorded. The mean age of the patients was 59.1±22.0 years and the mean length of stay in the intensive care unit was 42.3±35.5 days (range, 11-207 days). Overall, complications developed in 22 (15.6%) patients, of which 10.7% were early complications (1.4% related to the tube, 5.8% minor and 3.5% major complications). Tube- related complications were seen to develop in two patients. In the evaluation of the early minor complications, the most frequently seen complication was minor bleeding in 5.8% of the patients. No major vessel bleeding was determined in any patient in the early or late period. Of the late complications, the infection was seen to develop in four (2.8%) patients and stenosis in three (2.1%). The combination of flexible lightwand and USG in the PDT procedure minimized tube-related complications and contributed to the prevention of bleeding complications.

Protective effects of laparoscopic sleeve gastrectomy on atherosclerotic and hemocytic parameters in obese patients.

OBJECTIVES: The aim of this study was to evaluate the effects of the change in the body mass index following laparoscopic sleeve gastrectomy on the vascular morphology structure and biochemical and hemocytic parameters. MATERIAL AND METHODS: A prospective evaluation of 60 patients who underwent sleeve gastrectomy was conducted. The relationship was evaluated between the vascular morphological parameters and biochemical and hemocytic inflammatory variables of the patients preoperatively and at 6, 12, and 18 months postoperatively. RESULTS: Compared to the baseline values, a significant decrease was determined in the carotid intima media thickness at 6, 12, and 18 months (p<0.001, p<0.001, p<0.001, respectively). The compliance and distensibility values were observed to increase over time (p<0.05, p<0.001, p<0.001, respectively). A statistically significant difference was determined in the carotid intima media thickness values according to gender, with males (n:7) measuring 0.618±0.123 mm and females (n:53) measuring 0.506±0.113 mm (p<0.01). When patients were grouped as neutrophil-to-lymphocyte ratio ≤2.54 (n:41) and neutrophil-to-lymphocyte ratio>2.55 (n:19), the increasing neutrophil-to-lymphocyte ratio values were observed to be in proportion to the carotid intima media thickness, and the difference was statistically significant (p<0.001). When factors affecting the vascular morphology parameters measured at baseline and throughout the study were evaluated with the correlation analysis, there was observed to be a positive correlation between the baseline carotid intima media thickness thickness and neutrophil percentage (r=0.736, p<0.001) and neutrophil-to-lymphocyte ratio (r=0.676, p<0.001), and between the negative correlation and lymphocyte percentage (r=-0.628, p<0.001). CONCLUSION: Laparoscopic sleeve gastrectomy is not only a cosmetic procedure reducing the body mass index values, but it also has a beneficiary effect on vascular morphology, biochemical, and hemocytic parameters.
