Single versus double Hem-o-lok clips to secure the apendiceal stump during laparoscopic appendectomy: a prospective randomized multicentric clinical trial.

PURPOSE: Polymeric clips (Hem-o-lok ligation system) are now widely used to securing the base of the appendix during laparoscopic appendectomy. Studies comparing the use of single or double hem-o-lok clips are limited. The aim of this study was to compare the reliability of a single hem-o-lok clips with a double hem-o-lok clips for closure of an appendiceal stump. METHODS: This prospective randomized study includes patients from two centers who underwent laparoscopic appendectomy with the diagnosis of appendicitis between September 2020 and March 2023. Demographic, operative and clinical outcomes of the use of single or double hem-o-lok clips for closure of the appendiceal stump were compared. Factors affecting long postoperative hospital stay were investigated using univariate and multivariate analyzes. RESULTS: One hundred forty two (48.3%) patients in the single hem-o-lok arm and 152 (51.7%) patients in the double hem-o-lok arm were included in the analysis.The shortest operative time was noted in the single hem-o-lok group (52.1 ± 19.9 versus 61.6 ± 24.9 min, p < 0.001). The median hospital stay was 1 day (range 1-10) in the single hem-o-lok group and 1 day (range 1-12) in the double hem-o-lok group, and was shorter in the single hem-o-lok arm (1.61 ± 1.56 vs 1.84 ± 1.69, p = 0.019). Based on multivariate analysis, drain placement was identified as an independent predictive factor for long hospital stay. CONCLUSIONS: The use of single hem-o-lok clips for appendiceal stump closure during laparoscopic appendectomy is safe and effective. Trial registration NCT04387370 ( http://www.

Synchronous celiac artery and superior mesenteric artery compression syndrome: The effect of collateral circulation on the treatment procedure.

Background: Maintaining collateral circulation is highly important in the stenosis of celiac artery (CA), superior mesenteric artery (SMA), and inferior mesenteric artery (IMA). The SMA compression is commonly reported to be accompanied by the CA compression caused by the median arcuate ligament (MAL) while the synchronous compression of CA and SMA by other ligaments has been rarely reported. Case Presentation: In this report, we present a 64-year-old female patient who presented with a postprandial abdominal pain and weight loss. Initial evaluation indicated a synchronous compression of CA and SMA caused by MAL. The patient was planned for laparoscopic MAL division due to the presence of sufficient collateral circulation between the CA and SMA that was facilitated through the superior pancreaticoduodenal artery. Following laparoscopic release, the patient improved clinically and postoperative imaging indicated that the compression on the SMA was still present and the collateral circulation was sufficient. Conclusion: We suggest that laparoscopic MAL division can be the primary method of choice in cases with sufficient collateral circulation between the CA and SMA.

Phylogenetic analysis based on the ITS, matK and rbcL DNA barcodes and comparison of chemical contents of twelve Paeonia taxa in Türkiye.

BACKGROUD: Twelve taxa of herbaceous Paeonia species were recorded in Türkiye. All definitions were performed morphologically and/or anatomically and there is no study based on DNA barcode sequences. Three barcode regions were sequenced to determine the phylogenetic relationships of Turkish Paeonia taxa. The chemical comparison of roots was also investigated. METHODS AND RESULTS: The taxons were collected between May and June 2021 from nine cities. Leaf materials were used for DNA isolation and ITS, matK and rbcL regions were amplified and sequenced. There was no difference among taxa in terms of rbcL sequences. But the ITS and matK regions distinguished 12 taxa and structured them in two groups. ITS region distinguished P. peregrina, P. arietina, and P. tenuifolia from other taxa, while matK region distinguished P. arietina and P. witmanniana from other taxa. Both barcode sequences actually showed that the registration of P. mascula subsp. arasicola was actually 100% similar to P. arietina. ITS was the most polymorphic region (n = 54) followed by matK (n = 9). These sequences could successfully discriminate Paoenia species from each other and diploid P. tenuifolia. The methanolic root (100 gr) extracts were examined for total phenolic and flavonoid content, and antioxidant activities. Significant variation was found for polyphenolic content, and antioxidant properties (TPC from 204.23 to 2343.89 mg, TFC from 7.73 to 66.16 mg, and FRAP from 523.81 to 4338.62 mg). SC50 values of ABTS and DPPH were ranged from 115.08 to 1115.52 µg/ml and 73.83 to 963.59 µg/ml, respectively. CONCLUSION: It was concluded that 11 of 12 taxa had differences in terms of ITS and matK sequences and these region must be used for the correct identification of Turkish Paeonia.

Symptom progression following on-pump versus off-pump coronary artery bypass graft surgery in patients with peripheral arterial disease.

OBJECTIVE: This study aims to examine whether cardiac surgery leads to symptom progression in the early postoperative period in patients with the peripheral arterial disease (PAD) and evaluate the difference between on-pump (OPCAB) and off-pump (ONCAB) coronary artery bypass graft surgery with regard to the symptom progression. METHODS: This retrospective study included one hundred consecutive adult patients with PAD at Fontaine stage 2b (pain-free walking distance less than 100 m) undergoing ONCAB and one hundred consecutive adult patients with PAD at Fontaine stage 2b (pain-free walking distance less than 100 m) undergoing OPCAB. Symptom progression was defined as the development of ischemic rest pain (Fontaine stage 3). RESULTS: In the first week after surgery, 12 patients in the OPCAB group and 53 patients in the ONCAB group had postoperative symptom progression (p < 0.001). Rest pain resolved in most of these patients on the 15th postoperative day. At the end of the second month, rest pain resolved in all patients. Logistic regression analysis revealed that cardiac surgery with CPB, ABI < 0.5, postoperative nadir hct levels ≤ 25%, and intraoperative tissue hypoxia were independently associated with postoperative symptom progression. CONCLUSIONS: In summary, we found that cardiac surgery may lead to symptom progression in patients with severe claudication in the early postoperative period. Our results suggest that OPCAB may lead to lower rates of symptom progression compared to ONCAB.

Low-Dose Methotrexate Use in Idiopathic Granulomatous Mastitis: An Alternative Treatment Method.

BACKGROUND: Idiopathic granulomatous mastitis (IGM) is a rare, recurrent and progressive breast disease with an unknown etiology. Patients with IGM will probably face stressful, time-consuming treatment procedures with side effects due to medications. There are different treatment modalities in clinical use including medical and surgical interventions. OBJECTIVE: The aim of this study was to present the results of using the combination therapy of low-dose methotrexate (MTX) and steroid in IGM. METHODS: Seventeen patients diagnosed with IGM and treated with MTX were included into the study. Low-dose MTX at 5 mg/week and 8 mg/day prednisone were given for 2-3 months. RESULTS: After 2-3 months of treatment, 10 patients exhibited (58.5%) complete, 3 patients (17.6%) partial recovery, and no response to the treatment process was observed in 4 patients (23.5%). No side effects of MTX and recurrent events were noted in any of the patients. CONCLUSION: Low-dose MTX and prednisone treatment for IGM patients, who did not respond to steroids alone, should be considered as an alternative treatment method instead of surgical intervention.

Evaluation of the effect of intraperitoneal etanercept administration on oxidative stress and inflammation indicators in the kidney and blood of experimental sepsis-induced rats.

INTRODUCTION: Sepsis is an important cause of mortality and morbidity, and inflammatory response and oxidative stress play major roles underlying its pathophysiology. Here, we evaluated the effect of intraperitoneal etanercept administration on oxidative stress and inflammation indicators in the kidney and blood of experimental sepsis-induced rats. METHODS: Twenty-eight adult Sprague Dawley rats were classified into Control (Group 1), Sepsis (Group 2), Sepsis+Cefazolin (Group 3), and Sepsis+Cefazolin+Etanercept (Group 4) groups. Kidney tissue and serum samples were obtained for biochemical and histopathological investigations and examined for the C reactive protein (CRP), tumor necrosis factor-alpha (TNF-α), triggering receptor expressed on myeloid cells (TREM), and malondialdehyde (MDA) levels. RESULTS: The levels of TNF-α, TREM, and MDA in serum and kidney samples were significantly higher in rats from sepsis group than in rats from control group (p < 0.05). Group 3 showed a significant reduction in serum levels of TNF-α, CRP, and TREM as compared with Group 2 (p < 0.05). Serum TNF-α, CRP, TREM, and MDA levels and kidney TNF-α and TREM levels were significantly lower in Group 4 than in Group 2 (p < 0.05). Serum TNF-α and TREM levels in Group 4 were significantly lower than those in Group 3, and histopathological scores were significantly lower in Group 3 and Group 4 than in Group 2 (p < 0.05). Histopathological scores of Group 4 were significantly lower than those of Group 3 (p < 0.05). CONCLUSIONS: Etanercept, a TNF-α inhibitor, may ameliorate sepsis-induced oxidative stress, inflammation, and histopathological damage.

Rare Undifferentiated Tumour of Thyroid: Primary Thyroid Fibrosarcoma.

Primary thyroid fibrosarcoma cases are very rare. Although it is a known fact that soft tissue sarcomas show slow growth, there have been some cases in literature similar to our case in which there was a fast-growing tumour tissue causing breathing and swallowing difficulties due to painless pressure. For diagnosis, there is no specific clinical or radiological finding. We report a 67-year-old male with a mobile fast-growing mass covering almost all over the neck that appeared 2 months prior to the admission. Laboratory findings showed that the patient was euthyroid. Fine needle aspiration biopsy results are consistent with suspicion of a mesenchymal, histiocytic, epithelial or lymphoid tissue origined malignancy. Patient was taken into surgical operation. The thyroid tissue invaded the main vascular structure, trachea and esophagus. Due to this situation R1 resection was applied. Immunohistopathological examination showed a conventional type of fibrosarcoma. After the surgery, radiotherapy and chemotherapy had been planned and applied. Patients died before the radiotherapy sessions ended. It should be kept in mind that a rapid growth in thyroid tissue can be thyroid fibrosarcoma, there could be a rapid clinical course and poor prognosis after operation.

Superior mesenteric artery (Wilkie's) syndrome: a rare cause of upper gastrointestinal system obstruction.

Background Superior mesenteric artery syndrome (SMAS) results from the compression of the third part of the duodenum between the aorta and the proximal part of the superior mesenteric artery (SMA). Clinical presentation of SMAS is characterized by the dilatation of the proximal part of the third part of the duodenum. SMAS is a rare cause of the upper gastrointestinal system (UGS) obstruction. In this study, we aimed to present our clinical experience in the treatment of five patients with SMAS, which is a rare clinical condition requiring surgery. Patients and methods The retrospective study included five patients who were treated due to SMAS at our clinic between January 2010 and January 2014. Results All the patients were underweight, with a mean BMI of 15.73 (14-16). The clinical symptoms included epigastric pain after food intake, large volume bilious emesis, early satiety, failure to gain weight, indigestion, esophageal reflux, sense of fullness, and persistent weight loss. SMAS was diagnosed using barium meal studies, upper gastrointestinal endoscopy, abdominal ultrasonography, and CT angiography. Four patients underwent duodenojejunostomy and one patient was managed with gastrojejunostomy. No complication was observed during the postoperative period, and all the patients achieved significant improvement in symptoms. Conclusion SMAS is a rare cause of UGS obstruction, and the diagnosis of SMAS is often delayed. SMAS should be suspected in the differential diagnosis of the patients with unsubstantiated symptoms of persistent nausea, emesis, and significant weight loss.

Effect of Intraperitoneal Etanercept on Oxidative Stress in Rats with Peritonitis.

Our aim was to evaluate effect of etanercept on oxidative stress parameters in rats with experimental peritonitis and investigate the availability of etanercept usage in the treatment of peritonitis in the future. Twenty-eight rats were divided into four groups as control (group 1), peritonitis (group 2), peritonitis + cefazolin sodium (group 3), and peritonitis + cefazolin sodium + etanercept (group 4). Peritoneal tissue and blood samples were taken from all of the rats for histopathological and biochemical examination. The oxidative stress parameters were examined in blood and tissue samples. It was observed that rats with peritonitis benefit from cefazolin sodium treatment. Evaluating the effectiveness of etanercept was our main objective for this study. In this perspective, we compared group 3 and group 4 and found statistically significant decreases in oxidative parameters and statistically significant increases in antioxidants in serum and tissue samples in group 4. It is observed that there was a significant contribution of etanercept on biochemical and also histopathological results. As a result, the TNF-α inhibitor, etanercept, in addition to antibiotics given in the early treatment of peritonitis results in more significant improvement of histopathological and oxidative parameters as compared to antibiotics alone.

The potential beneficial effects of ethyl pyruvate on diabetic nephropathy: an experimental and ultrastructural study.

Oxidative stress is one of the main causes of diabetic nephropathy, which is a complication of diabetes mellitus (DM). The aim of this study was to investigate the possible role of ethyl pyruvate (EP) in streptozotocin-induced diabetic rats' kidney. Four groups (n = 8) of male Wistar albino rats were used as follows: control group rats received only sodium citrate buffer solution intraperitoneally (ip). The EP group was given 50 mg/kg EP ip. In the DM group, diabetes was induced by streptozotocin. The DM + EP group received 50 mg/kg EP ip. All animals received daily treatment for 14 days, and at the end of the study the kidneys were removed: the left kidney of the rats was used for malondialdehyde (MDA) analysis and the right kidney for histological examination. There was normal appearance of the kidney tissues in the control and the EP-administered groups. In the DM group, there was evident basement membrane thickening and enlargement of mesangial matrix; swelling in some tubular epithelial cells was also noticeable. In the DM+EP administered group, nearly the same appearance as the control group and relative thickening in the glomerular basal membrane were observed. The antioxidant effect of ethyl pyruvate improved the renal structures in the DM + EP group.

Comparison of anti-reflux mechanism between Double-J-Stent and standart Double-J-Stent use for risk of BK nephropathy and urinary tract Infection in kidney transplantation.

OBJECTIVES: There are studies that show that double J stenting (DJS) increase BK nephropathy (BKN) 4 fold. DJS may cause vesicoureteral reflux (VUR) with normal bladder contraction. The aim of this study is to comparison risk of BKN, urinary tract infections (UTI) and postoperative urologic complications with the use DJS with anti-reflux device (ARD-DJS) and standart double J stent (St-DJS). Matherial and methods: Ninety patients (male/female: 50/40) that had undergone kidney transplantations in Diyarbakir Training and Research Hospital and Dicle University, Faculty of Medicine Hospital between January 2012 and April 2015 were enrolled in the study. Demographic data, immunosuppression protocols, presence of rejection, graft loss, postoperative urologic complications, UTI, plasma BK levels of the patients were evaluated retrospectively. RESULTS: Median and IQR follow up time for ARD-DJS and St-DJS patients were 14 (12-18) months and 25 (16-30) months respectively. Five cases (5.5%) had BK viremia (P=0.025). All 5 cases with BK viremia were St-DJS users. CONCLUSION: As a result for postoperative UTI and postoperative urinary complication risk there were no statistically significant difference between ARD-DJS use and St-DJS use during ureteral anastomosis. BKN univariate analysis were significantly less than those st-DJS used. Risc factors were evaluated. But results were not statistically significant in the logistic regression analysis. We think that to demonstrate this benefit, we need randomized controlled studies with more patients and longer follow up.

Value of serial platelet indices measurements for the prediction of pulmonary embolism in patients with deep venous thrombosis.

BACKGROUND: To date, no validated biomarkers with high sensitivity and specificity have been established for diagnosis of pulmonary embolism (PE) in patients with deep venous thrombosis (DVT). There is a need to develop simple and reliable noninvasive tests that can accurately identify patients with PE, even in small hospitals or clinics. The aim of this study was to investigate the value of mean platelet volume (MPV) and platelet distribution width (PDW) for predicting occurrence of PE in patients with DVT. METHODS: Records of acute DVT patients were reviewed retrospectively. Group 1 consisted of 50 patients with acute DVT and group 2 consisted of 50 patients with acute DVT who developed PE during follow-up. The control group consisted of patients with uncomplicated primary varicose veins of the lower limbs. Venous peripheral blood samples for measurement of MPV, PDW, and platelet count were drawn on admission, before the treatment, and at the time of PE diagnosis. RESULTS: MPV and PDW levels at the time of PE diagnosis were higher in group 2 than group 1 (P<0.001 and P=0.026, respectively). Receiver operating characteristics analysis revealed that a 5.2% increase in admission PDW during follow-up provided 70% sensitivity and 82% specificity (area under the curve, 0.80), and a 6.6% increase in admission MPV during follow-up provided 74% sensitivity and 83% specificity (area under the curve, 0.84) for prediction of PE occurrence in patients with DVT. PDW and MPV levels at the time of PE diagnosis were found to be independent risk factors for the occurrence of PE in patients with DVT. CONCLUSION: Serial measurements of MPV and PDW, and percent change in MPV and PDW appears to be a useful marker for predicting occurrence of acute PE in patients with a first episode of acute proximal DVT.

Relationship between thyroid function and carotid artery plaque ulceration.

Carotid artery plaque ulceration (PU) is known to be associated with cerebrovascular events (CVE). Even within euthyroid ranges, thyroid function has been reported to be associated with carotid atherosclerosis. However, the relationship between thyroid function and carotid PU remains unclear. Our aim was to determine the relationship between thyroid function and PU in patients with internal carotid artery stenosis (ICS). Records of patients with CVE were retrospectively reviewed. A total of 250 consecutive patients with ICS who had computed tomography angiography (CTA) of the carotid arteries following hospitalization were included in the study. CTA was used for the evaluation of carotid artery plaque morphology and ulceration. Plaque morphology was classified as fatty, mixed or calcified. Patients were divided into two groups according to the presence or absence of PU. Subclinical hypothyroidism (SCH) and hypothyroidism were significantly more common in patients with PU (p < 0.001 and p = 0.003, respectively). Patients with PU had higher incidence of low-normal FT4 levels (p = 0.02). Compared with patients who had no PU, patients with PU had decreased FT4 levels and elevated TSH levels (p = 0.001 and p = 0.001, respectively). TSH level (OR 1.33, p = 0.001), SCH (OR 4.2, p = 0.001), hypothyroidism (OR 3.15, p = 0.037), fatty plaque (OR 2.16, p = 0.01) and calcified plaque (OR 0.19, p < 0.001) were independently associated with PU. Our results suggest that SCH and hypothyroidism could be a risk factor for PU and subsequent CVE. Thyroid functions may be useful for risk stratification of patients with ICS.

Value of platelet indices in identifying complete resolution of thrombus in deep venous thrombosis patients.

We aimed to evaluate whether mean platelet volume (MPV) and platelet distribution width (PDW) are helpful to identify complete thrombus resolution (CTR) after acute deep venous thrombosis (DVT). Patients who had first-time episode of acute proximal DVT were included in this retrospective study. 100 patients with DVT were divided into two groups according to absence (group 1; n = 68) or presence (group 2; n = 32) of CTR on doppler ultrasonography at month 6. There were no significant difference in admission MPV and PDW levels between group 1 and group 2. MPV (p = 0.03) and PDW (p < 0.001) levels at month 6 were significantly higher in group 1 than in group 2. CTR showed a moderate negative correlation with PDW at month 6 (ρ = -0.47) and a weak negative correlation with MPV at month 6 (ρ = -0.26). Logistic regression analysis showed that PDW (OR, 2.2; p = 0.004) at month 6 was an independent risk factor for the presence of residual venous thrombosis in DVT patients. Receiver operating characteristics analysis revealed that a 8.4 % decrease in admission MPV at month 6 provided 62 % sensitivity and 62 % specificity (AUC: 0.64) and a 15.4 % decrease in admission PDW at month 6 provided 87 % sensitivity and 94 % specificity (AUC: 0.89) for prediction of CTR in DVT patients. Percent change in admission MPV and PDW levels at month 6 may be used to identify the patients with CTR after a first episode of acute proximal DVT.

Relationship between nadir hematocrit during cardiopulmonary bypass and postoperative hyperglycemia in nondiabetic patients.

BACKGROUND: Hyperglycemia is common after cardiac surgery in both diabetic and nondiabetic patients and is associated with increased morbidity and mortality. Association between nadir hematocrit levels on cardiopulmonary bypass (CPB) and postoperative hyperglycemia is not clear. This study was carried out to determine the relationship between nadir hematocrit during CPB and postoperative hyperglycemia in nondiabetic patients. METHODS: Records of 200 nondiabetic patients undergoing coronary artery bypass grafting operation were retrospectively reviewed. In the first analysis, patients were divided into two subgroups according to the presence or absence of hyperglycemia. Further analysis was made after dividing the patients into 3 subgroups according to nadir hematocrit levels on CPB (less than 20%; 20% to 25%; greater than or equal to 25%). RESULTS: Compared to patients without hyperglycemia, patients with postoperative hyperglycemia had significantly lower preoperative hematocrit levels (p = 0.004) and were associated with lower nadir hematocrit levels during CPB (p= 0.002). Peak intensive care unit blood glucose levels and number of blood transfusions were significantly higher in patients with nadir hematocrit levels less than 20. (p<0.001 and p<0.001 respectively). Logistic regression analysis demonstrated that nadir hematocrit levels less than 20% (OR 2.9, p=0.009) and allogenic blood transfusion (OR 1.5, p=0.003) were independently associated with postoperative hyperglycemia. CONCLUSIONS: Nadir hematocrit levels on CPB less than 20% and allogenic blood transfusions were independently associated with postoperative hyperglycemia in nondiabetic patients. Patients with a nadir hematocrit levels less than 20 % during CPB should be closely monitored for hyperglycemia in the perioperative period.

Acute Acalculous Cholecystitis due to Viral Hepatitis A.

Inflammation of the gallbladder without evidence of calculi is known as acute acalculous cholecystitis (AAC). AAC is frequently associated with gangrene, perforation, and empyema. Due to these associated complications, AAC can be associated with high morbidity and mortality. Medical or surgical treatments can be chosen according to the general condition of the patient, underlying disease and agent. Particularly in acute acalculous cholecystitis cases, early diagnosis and early medical treatment have a positive effect on the patient and protect them from surgical trauma. ACC is a rare complication of acute viral hepatitis A. Herein, we present an adult patient of acalculous cholecystitis due to acute viral hepatitis A. She responded to the conservative management.

Monophasic synovial sarcoma of the pharynx: a case report.

Synovial sarcomas are a rare form of soft tissue sarcomas. We present a case of a 62 year-old male presenting with a left thyroid lump initially though to be a thyroid adenoma but subsequently diagnosed as a monophasic synovial sarcoma of the pharynx. We discuss the diagnosis and treatment of this case.

Spontaneous ruptured splenic artery aneurysm: a case report.

Splenic artery aneurysms are rare. We discuss a case of a 58-year-old gentleman presenting with collapse and shock secondary to spontaneous splenic artery aneurysm rupture. Patient underwent laparotomy and splenectomy then discharged home within a week of presentation.
