A Rare Case of Castleman's Syndrome Presenting with a Mass in the Bifurcation of the Celiac Trunk.

INTRODUCTION: Castleman's disease is an extremely rare disease in the abdomen region characterized by benign lymphoepithelial proliferation. CASE PRESENTATION: We report a case of a 63-year-old female who presented with abdominal pain. Abdominal CT Angio and dynamic contrast-enhanced abdominal MRI revealed a mass lesion showing markedly contrast enhancement, no vascular invasion sign, and diffusion restriction lesion in the truncus coelicus bifurcation region. The mass was surgically resected completely. Pathological evaluation showed a hyaline-vascular type of Castleman's disease. CONCLUSION: Castleman's disease should be kept in mind in the differential diagnosis of an isolated intra-abdominal mass.

For this purpose, we conducted a three-stage consensus-building approach. Results: Six topics, including diagnosis, medical treatment, percutaneous treatment, surgical treatment, management of complications and posttreatment follow-up and recurrences in HCE were discussed. Conclusion: The expert panel made recommendations for every topic.

Management of Spontaneous Major Rectus Sheath Hematoma in a COVID-19 Patient: A Case Report and Literature Review.

A rectus sheath hematoma, which is mostly encountered due to abdominal traumas or anticoagulant use, can be challenging, and a delayed diagnosis may lead to hypovolemic shock and even death. In this study, we aimed to present the management of a case of rectus sheath hematoma that developed in a patient who was hospitalized and under coronavirus disease 2019 (COVID-19) treatment. A 70-year-old female patient was admitted to the intensive care unit (ICU) due to respiratory failure and developed a sudden onset of tachycardia and hypotension. The patient was then diagnosed with a rectus sheath hematoma and after ensuring hemodynamic stability she was treated with angiographic embolization. Following the treatment, the patient remained hemodynamically stable and a control computed tomography (CT) revealed regression in the hematoma. Rectus sheath hematomas especially accompanied by additional comorbidities or aggressive surgical interventions may result in high mortality rates in the early period. It should also be kept in mind that during the COVID-19 pandemic, which has affected the world in the last two years, rectus sheath hematomas may be the underlying cause of sudden hypotension and abdominal distension, and it should not be forgotten that angiographic embolization performed by experienced interventional radiologists is the mainstay of treatment in cases where hemodynamic stability can't be achieved.

Magnetic Nanoparticle-Based Electrochemical Sensing Platform Using Ferrocene-Labelled Peptide Nucleic Acid for the Early Diagnosis of Colorectal Cancer.

Diagnostic biomarkers based on epigenetic changes such as DNA methylation are promising tools for early cancer diagnosis. However, there are significant difficulties in directly and specifically detecting methylated DNA regions. Here, we report an electrochemical sensing system based on magnetic nanoparticles that enable a quantitative and selective analysis of the methylated septin9 (mSEPT9) gene, which is considered a diagnostic marker in early stage colorectal cancer (CRC). Methylation levels of SEPT9 in CRC samples were successfully followed by the selective recognition ability of a related peptide nucleic acid (PNA) after hybridization with DNA fragments in human patients' serums and plasma (n = 10). Moreover, this system was also adapted into a point-of-care (POC) device for a one-step detection platform. The detection of mSEPT9 demonstrated a limit of detection (LOD) value of 0.37% and interference-free measurement in the presence of branched-chain amino acid transaminase 1 (BCAT1) and SRY box transcription factor 21 antisense divergent transcript 1 (SOX21-AS1). The currently proposed functional platform has substantial prospects in translational applications of early CRC detection.

Major Surgical Resections in Abdominopelvic Sarcomas: Clinical Features and Results of 38 patients: A Tertiary-Center Experience.

Introduction: Sarcomas with mesenchymal origin located in the abdominal cavity or retroperitoneal space are rare. They might reach large dimensions due to the non-specific and late onset of clinical symptoms. In this study we aim to provide the outcomes of 38 cases. Methods: Thirty-eight patients, whose data had been registered and analyzed completely in a prospective manner, were enrolled in the study. Demographic Findings, Primary-Recurrent Status of the disease, surgical method applied (R0-1-2), additional organ resections, Morbidity and Mortality rates, HIPEC application, Histopathological results and overall survival outcomes during follow-up were evaluated in the enrolled cases. Results: Thirty-eight (38) patients were operated on due to soft tissue sarcomas located in the abdominal and retroperitoneal area. The mean age of patients was 57.63 +- 15.38. The localization rates of retroperitoneal, abdominal and visceral tumors were 28%, 58%, and 12%, respectively. The mean tumor size was 12.96 cm +- 9.62. Twenty-seven patients (71%) underwent R0 resection, 7 patients (18%) underwent R1 resection, 4 patients (10%) underwent R2 resection. Additionally, sarcomatosis was detected in 6 patients and these patients underwent Cytoreductive Surgery+HIPEC. The first 30-day mortality and morbidity rates were 10.5% (4 patients) and 44% (17 patients), respectively. Conclusion: Surgery is the gold standard treatment of this condition. The most important stage in the management of the condition is the discussion of these cases in multidisciplinary teams in centers experienced in this disease in terms of prognosis and local recurrence and deciding on the treatment strategy based on these discussions.

Effect of L-carnitine on regeneration in experimental partial hepatectomy model in rats.

BACKGROUND: In cases of major liver resections or ischemic damage made by the pringle maneuver, agents that increase regeneration or manage ischemic reperfusion injury have become a fascinating topic for researchers. The aim of this study is to see how systemic L-carnitine, an antioxidant with thorough research behind it, affects liver regeneration after major hepatectomy in a rat experimental hepatectomy (two-thirds liver resection) model. METHODS: The liver regeneration was evaluated in this study using a rat hepatectomy model developed in the General Surgery Clinic of Health Sciences University, Umraniye Education and Research Hospital's Laboratory. In the experiment, 15 male and 15 female Wistar Albino rats weighing between 250 and 300 g were used in a way that the genders were mixed. In each group, three groups were formed, including male and female rats randomly selected and ten rats. Gcontrol: 70% hepatic resection + intraperitoneal 0.9% saline, GSham: After laparotomy, the abdomen was closed again without any procedure, Gcarnitine: 70% hepatic resection + intraperitoneal 100 mg/kg L Carnitine was applied. It was applied systemically to GSham and Gcarnitine groups and the same procedure was applied to rats for 4 days at the same time without any restrictions. On the 5th day, the abdomen was entered with relaparotomy after sacrification and liver regeneration was evaluated macroscopically and recorded in the forms developed for each subject. Later, liver tissue was resected and microscopically recorded by measuring mitotic index, binuclear hepatocyte, gall duct proliferation, dilation in central veins, and cell proliferation in the parenchyma. The results obtained were evaluated statistically. RESULTS: According to the results, the L-carnitine group had a statistically significant increase in overall regeneration scoring after hepatectomy in the histopathological assessment as compared to the control group. CONCLUSION: It is thought that L-carnitine, whose many positive effects have been shown experimentally and clinically, has a positive effect on liver regeneration and immunohistochemical researches is required to elucidate this pathway.

The Role of CO-RADS Scoring System in the Diagnosis of COVID-19 Infection and its Correlation with Clinical Signs.

BACKGROUND: Computed tomography (CT) evaluation systematics has become necessary to eliminate the difference of opinion among radiologists in evaluating COVID-19 CT findings. INTRODUCTION: The objectives of this study were to evaluate the efficiency of CO-RADS scoring system in our patients with COVID-19 as well as to examine its correlation with clinical and laboratory findings. METHODS: The CO-RADS category of all patients included in the study was determined by a radiologist who did not know the rtRT-PCR test result of the patients, according to the Covid-19 reporting and data system of Mathias Prokop et al. Results: A total of 1338 patients were included. CT findings were positive in 66.3%, with a mean CO-RADS score of 3,4 ± 1,7. 444 (33.1%) of the patients were in the CO-RADS 1-2, 894 (66.9%) were in the CO-RADS 3-5 group. There were positive correlations between CO-RADS score and age, CMI, hypertension, diabetes mellitus, chronic pulmonary diseases presence of symptoms, symptom duration, presence of cough, shortness of breath, malaise, CRP, and LDH, while CORADS score was negatively correlated with lymphocyte count. The results of the ROC analysis suggested that those with age ≥40 years, symptom duration >2 days, CMI score >1 and/or comorbid conditions were more likely to have a CO-RADS score of 3-5. CONCLUSION: The CO-RADS classification system is a CT findings assessment system that can be used to diagnose COVID-19 in patients with symptoms of cough, shortness of breath, myalgia and fatigue for more than two days.

Cytoreductive Surgery versus Systemic Chemotherapy alone in Isolated Peritoneal Carcinomatosis of Colorectal Origin.

OBJECTIVE: To compare the overall survival and progression-free survival of front-line cytoreductive surgery (CRs) ± hyperthermic intraperitoneal chemotherapy versus intensive systemic chemotherapy alone, in patients with isolated peritoneal carcinomatosis of colorectal origin. STUDY DESIGN: Descriptive study. PLACE AND DURATION OF STUDY: Departments of Medical Oncology and Surgical Oncology in University of Health Sciences, Umraniye Education and Research Hospital, from January 2017 to January 2020. METHODOLOGY: Clinicopathological data of patients presented with isolated peritoneal carcinomatosis were categorised into two groups according to their treatment type as patients who received intensive systemic chemotherapy alone or underwent front-line CRS ± HIPEC. Overall and progression-free survival outcomes of the two approaches were quantified by survival analysis and compared with each other. The other collected variables were age, gender, performance status, tumor site and type of systemic chemotherapy. RESULTS: Overall, 109 patients were included. The median progression-free survival of patients treated with cytoreductive surgery ± hyperthermic intraperitoneal chemotherapy was 12 months; whereas, it was 9 months in those treated with intensive systemic chemotherapy alone (p=0.011). The median overall survival was estimated as 32 months in patients treated with cytoreductive surgery ± hyperthermic intraperitoneal chemotherapy, compared with 23 months for those treated with systemic chemotherapy alone (p=0.715). CONCLUSION: Although not translated into overall survival gain, extended progression-free survival, may give an advantage to cytoreductive surgery ± hyperthermic intraperitoneal chemotherapy when used with intensive systemic chemotherapy in the individualised treatment of isolated peritoneal carcinomatosis of colorectal carcinoma. Key Words: Colorectal carcinoma, Cytoreductive surgery, Hyperthermic intraperitoneal chemotherapy, Overall survival, Peritoneal carcinomatosis, Systemic chemotherapy.

The Effects of Ankaferd on Liver Regeneration after Partial Hepatectomy in Rats.

Background: In this study, we aim at investigating the effect of post partial hepatectomy Ankaferd blood stopper (ABS) on liver regeneration in rats. Methods: Twenty-four rats were included in our study divided into three groups. (Group A = (Sham) 8 rats, Group B = (control) 8 rats, Group C = (experimental) 8 rats). Two-thirds hepatectomy was employed in all rats. Intraperitoneal 0.9% saline was administered to the rats in the control group, and intraperitoneal 1 ml Ankaferd was administered to the rats in the experimental group. The rats were sacrificed on the 7th day. Tissue samples were taken from the liver tissue for histopathological evaluation. Results: The number of mitosis and the cytoplasmic vacuolization/hdyropic degeneration scores were statistically different between the groups (Group A: 11.63 vs Group B: 17.00 vs Group C: 8.88 (p:0.028) and Group A: 8.56 vs Group B: 16.63 vs Group C: 12.31 (p:0.034), respectively). The presence of binuclear hepatocytes score was p: 0.258 and disorganized distribution in cell proliferation in the parenchyma score was :0.076; There was no statistical difference between the groups. The number of mitosis was p:0116 for Group A-B, p:1.00 for Group A-C and p:0.017 for Group B-C Conclusions: Positive results indicating an increase in liver regeneration due to Ankaferd were not obtained in our study.

Clinical features and surgical outcomes of major urological interventions during cytoreductive surgery and hyperthermic intraperitoneal chemotheraphy.

BACKGROUND: Urinary system resections and reconstructions are needed in peritoneal carcinomatosis due to abdominal malignancies. The effect of hyperthermic intraperitoneal chemotherapy on these urological procedures after reconstruction remains uncertain. The aim of the study is to evaluate major urological interventions during cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in complex abdominal malignancies with peritoneal carcinomatosis. METHODS: Forty-four cases underwent surgical intervention related to the urinary system among 208 cases who underwent cytoreductive surgery and hyperthermic intraperitoneal chemotherapy because of peritoneal carcinomatosis. Urinary system procedures performed in these patients (radical-partial cystectomy, partial ureter resection ureteroneocystostomy, ureteroureterostomy, nephrectomy) were evaluated in terms of postoperative morbidity-mortality and survival. RESULTS: Urinary system resections were performed during cytoreductive surgery in a total of 44 cases. The mean age was 54 years (20-73). Patients were diagnosed with peritoneal carcinomatosis due to colorectal cancer in 21 (47.8%), ovarian cancer in nine (20.4%), sarcomatosis in five (11.4%), cervical cancer in four (9%) and other cancers (mesothelioma, uterus, breast, gastric) in five (11.4%) cases. Total nephrectomy was performed in three cases and partial nephrectomy in one case. Cystectomy was performed in 21 cases; 16 of these were partial and five were total cystectomies. Ureteroureterocystostomy with double J was performed in four cases and ureteroneocystostomy in 12 cases. While Clavian-Dindo grade 3-4 complications were seen in nine cases (20.4%), three cases (6.8%) became exitus during the first 30-day follow-up. CONCLUSIONS: Although urinary system involvements have been regarded as inoperable in the past, we think that with adequate experience radical urinary interventions performed in suitable patients can be carried out with acceptable morbidity and mortality as seen in our series.

The effect of Allium sativum in experimental peritoneal adhesion model in rats.

PURPOSE: To evaluate the effect of garlic on formation of postoperative adhesions in rats. METHODS: Twenty-four Sprague dawley rats were divided into three groups. In Group 1 (sham), laparotomy was performed and stitched up. In Group 2 (control), after laparotomy was performed, punctate hemorrhage was induced by cecal abrasion in the cecum and 2 cc of saline was intraperitoneally administered to each rat. In Group 3 (experimental), after laparotomy was performed, punctate hemorrhage was induced by cecal abrasion in the cecum and each rat was intraperitoneally administered a sterile Allium sativum derivative. The rats in all groups were re-laparotomized on postoperative day 7; samples were obtained from the peritoneal tissue surrounding the cecum. RESULTS: In Group 3, there was a statistically significant difference in terms of inflammation, lymph node size, and free oxygen radicals; these parameters tended to increase. In terms of fibrosis evaluated using H&E and MT, there was no significant difference between groups 2 and 3. CONCLUSIONS: No positive outcomes indicating that Allium sativum reduces intra-abdominal adhesions were obtained. However, it caused severe inflammation in the tissue. Additionally, in immunohistochemical analyses conducted to detect oxidative stress, allium sativum increased the production of free oxygen radicals in the tissue.

Synchronous pancreas and liver resection during CRS ± HIPEC. Results of 35 consecutive patients.

AIM: To evaluate the results of synchronous pancreas and liver resection in patients with metastatic carcinoma accompanied by peritoneal carcinomatosis (PC) who underwent cytoreductive surgery (CRS)/hyperthermic intraperitoneal chemotherapy (HIPEC). MATERIAL AND METHODS: Overall, 35 patients with PC who underwent CRS/HIPEC at Umraniye Education and Research Hospital owing to different etiological causes were evaluated for operation procedure, age, sex, comorbid diseases, ASA score, systemic chemo/radiotherapy, duration of surgery, chemotherapy (CT) protocol applied in HIPEC, amount of bleeding, synchronous hepatobiliary resection interventions during operation and short/long-term mortality and morbidity. RESULTS: Fifteen patients were male and 20 were female. Mean age was 58.375 ± 13.02 (range, 27-85) years. CRS/HIPEC was performed in 12 patients (34.3%), whereas only CRS was performed in 23 (65.7%) patients. The lowest and highest perioperative bleeding amount was 50 cc and 2000 cc, respectively, and 6 (17.1%) patients had intraoperative bleeding of ≥1000 cc. Synchronous isolated pancreatic resection, hepatic + pancreatic resection and isolated liver resection was performed in 3 (8.6%), 5 (14.3%) and 27 (77.1%) patients treated with CRS/HIPEC. Two patients died within postoperative day 30, and the mortality rate was 5.7%. CONCLUSION: Hepatopancreatobiliary surgery is a difficult intervention and is associated with serious morbidities. Synchronisation of hepatopancreatobiliary surgery with CRS/HIPEC may be challenging for the surgeon and clinician. Here we emphasise that this combination can be performed safely by an experienced team with a multidisciplinary approach and good patient preparation.

Necrotizing fasciitis after intramuscular self-injection A case report.

Necrotizing fasciitis (NF) is a rare, life-threatening soft tissue infection that affects the skin, subcutaneous tissue, fascia, and muscle, and is characterized by rapid spread and invasion of pathogens. Treatment is possible with early diagnosis, appropriate antibiotic therapy, and quick surgical intervention. Nevertheless, despite all interventions, it is sometimes difficult to manage NF. The Authors present the case of a patient with extensive NF caused by multidrug-resistant Acinetobacter baumannii (A. baumannii) that developed following an intramuscular injection of diclofenac sodium administered at home by someone who was not a healthcare professional. Wound sample culture revealed multidrug-resistant A. baumannii. The patient was treated using negative-pressure wound therapy along with antibiotic treatment and extensive surgical debridement. KEY WORDS: Multidrug-resistant acinetobacter baumannii, Necrotizing fasciitis, Negative-pressurelf-injection, Wound therapy.

A case of hepatocellular carcinoma mimicking hepatic adenoma.

Hepatocellular adenomas (HA) are benign naturally occurring masses that are rarely reported, and rarely reaching tumor size up to 30 cm. Hepatocellular carcinoma (HCC) is the most common primary malignancy of the liver and usually caused by cirrhosis and more commonly reported tumors in males. It has been reported that presentations may occur with masses that are often less than 5 cm or rarely more than 10 cm. We aimed to present a case of hepatocellular carcinoma 72-years old man with fatigue and pain spread on the right upper quadrant; a histopathologic image similar to both telangiectatic variant hepatic adenoma and false diagnosis as "cavernous hemangioma" in the first biopsy specimen. KEY WORDS: Hepatocellular carcinoma, Liver Adenoma.

A remnant suture can mimic malignancy after total thyroidectomy.

Foreign body reactions may develop against exogenous or certain endogenous materials. Cases of suture granuloma that develop against nonabsorbable suture material are rare complications of thyroid surgery. Because of these postoperative complications, a history of cancer prior to the operation suggests recurrence of cancer. Appropriate clinical, radiological, and pathological evaluation is highly important in such cases. Postoperative foreign bodies may remain undetected for years, but they sometimes cause lethal complications. KEY WORDS: Cancer mimicking, Foreign body, Suture granuloma, Thyroid surgery.
