Öğe A case of multiorgan resection for locally advanced stomach cancer(Turkish Surgical Assoc, 2013) Kucukkartallar, Tevfik; Gundes, Ebubekir; Yilmaz, Huseyin; Aksoy, FarukExtensive surgical resection may be required in locally advanced gastric cancers, with involvement of other organs. Our purpose was to present a case where vascular reconstruction was performed during multiple organ resections in a patient with locally advanced gastric cancer. An emergent laparotomy was performed on a patient who presented with upper gastrointestinal system hemorrhage; and he was diagnosed with locally advanced gastric cancer. Total gastrectomy, D II dissection, pancreaticoduodenectomy, transverse colectomy and end-to-end anastomosis were performed. Additionally, the superior mesenteric vein was partially excised and re-implanted to the portal vein. Neither recurrence nor distant metastasis was observed during the post-operative follow-up. Adjacent organ resections may be necessary for a curative treatment in locally advanced gastric cancer. In addition, partial resection and reconstruction may be required for extensive vascular invasion.Öğe Clinicopathological Characteristics of Gastroenteropancreatic Neuroendocrine Tumors 10 Years of Experience From a Single Center(Lippincott Williams & Wilkins, 2022) Senturk, Mustafa; Acar, Berkan; Yildirim, Mehmet Aykut; Cakir, Murat; Kucukkartallar, Tevfik; Vatansev, CelalettinObjectives Gastorenteropancreatic neuroendocrine (GEP-NET) tumors are the second most common tumors of the gastrointestinal tract. We aimed to investigate the clinicopathological features and factors affecting the prognosis of patients with GEP-NET. Methods Clinicopathological features of 158 patients were evaluated, including tumor location, TNM stage and grade, pathological features, presence of lymph nodes and distant metastases at the time of diagnosis, maximum tumor diameter and treatment details. Also, follow-up information was analyzed to discover possible prognostic factors. Results The most common primary site is pancreas (45.6%, n = 72). Most of the GEP-NETs were nonfunctional (93.6%, n = 148). Of the 158 patients, 94 (59.5%) were grade 1, 46 (29.1%) grade 2, and 18 (11.4%) grade 3. The 1-year, 3-year, and 5-year survival rates were 82.3% (130/158), 61.4% (70/114), and 47.2% (35/74), respectively. In multivariate analysis, histological grade (P = 0.04) and TNM stage (P < 0.001) were independent prognostic factors for survival in patients with GEP-NET. Conclusions They are increasing in frequency and are the most common tumors in the pancreas. Nonfunctional tumors made up the majority of cases. The main treatment was surgical resection. Histological grade and TNM stage are independent prognostic factors.Öğe Comparison of primary repair and repair with polyglycolic acid coated tube in recurrent laryngeal nerve cuts (an experimental study)(Excerpta Medica Inc-Elsevier Science Inc, 2020) Senturk, Mustafa; Cakir, Murat; Tekin, Ahmet; Kucukkartallar, Tevfik; Yildirim, Mehmet Aykut; Alkan, Selman; Findik, SiddikaBackground: Recurrent laryngeal nerve (RLN) injury is an important complication of thyroid surgery. In our study, we aimed to compare the effects of primary repair and polyglycolic acid (PGA) coated tube repair on nerve function and regeneration in RLN cuts in rats. Methods: Twenty seven rats were used for the study. Group-1 with only nerve cuts, group-2 with primary repair, and group-3 with conduit repair. The study was planned over two-stage surgery. In the first step, nerve defect formation and nerve repair were performed in the same session. In the second step, samples were taken from the subjects for histopathological. Results: Vocal cord mobility was proportionally higher in group-3 than other groups. However, there was no statistically significant difference between the groups (p < 0.239). The mean number of highest axons were detected the group-3. Conclusions: We think that PGA coated conduit can provide a more accurate orientation of nerve fibers by creating an isolated environment when compared to the primary repair. And this may be the cause of functional improvement in the nerve. (C) 2019 Elsevier Inc.

Methods: The study covers a total of 40 rats in 4 groups each having 10 rats. Group 1: The control group. Group 2: Normal saline group. Group 3: Sterile Novuxol (R) group. Group 4: The group where the intraperitoneal and systemic effects of sterile Novuxol (R) were investigated. Adhesion frequency and grades were scored on the post-op 11th day according to Granat. Blood work including hemoglobin, aspartate aminotransferase, alanine aminotransferase, urea, creatinine, and albumin level measurements were performed. Toxicity was investigated histopathologically through samples taken from the liver and the peritoneum from Group 4. Results: Adhesion frequency was found to be 80% on the right and 90% on the left for Group 1, while it was 50% on both left and right for Group 2, and 30% on the right and 10% on the left for Group 3. Adhesion stages were found to be 1: 2.35 +/- 1.42 for Group 1, 0.31 +/- 1.15 for Group 2, and 0.20 +/- 0.41 for Group 3. Adhesion stage of the Sterile Novuxol (R) Group was lower than all the other groups (p < 0.05). Biochemical and hematological parameters were similar in all groups (p > 0.05). Histopathological analysis revealed no hepatotoxicity. Conclusions: According to the results of our study, we believe that Sterile Novuxol (R) can be a good anti-adhesive agent considering its ease of use, non-toxicity, and effectiveness.

The reason why hypoxia develops in hepatopulmonary syndrome depends on the broadening of perialveolar capillary veins. Our study aims to investigate the effects of Flavanoid on hepatopulmonary syndrome through its inhibition of nitric oxide. Methods: Three groups, each having 8 rats, were formed within the scope of our study. Group I (the control group) only received laparatomy, group II received choledoch ligation, and group III was administered Flavanoid (90% flavonoid diosmin, 10% flavonoid hesperidin) following choledoch ligation. The rats were administered Flavanoid at week two following choledoch ligation. The rats' livers and lungs were examined histopathologically following a five-week follow-up and the perialveolar vein diameters were measured. Arterial blood gases and biochemical parameters were evaluated. Results: It was seen that fibrosis and oxidative damage in the liver with obstructive jaundice as well as hypoxia with pulmonary perialveolar vein sizes were significantly lower than the other group with cirrhosis formed through the administration of Flavanoid. Conclusion: We have concluded that Flavanoid administration might be useful in the treatment of hypoxia in hepatopulmonary syndrome and the delay of cirrhosis contraction.Öğe The Effects of Topical Insulin Application on Wound Healing(Modestum Ltd, 2015) Kargin, Suleyman; Tastekin, Didem; Kilic, Kemal; Cezik, Azamet; Cakir, Murat; Kucukkartallar, Tevfik; Kokbudak, NaileThe process of wound healing is a dynamic event during which the stages of fibroplasia, angiogenesis, and re-epithelization perfectly take place. The aim of this study is to compare the effects of wound irrigation by normal saline and topical insulin application, which we frequently use in clinical practice, on wound healing. The study covers a total of 20 male rats - 10 for the insulin group and 10 for the control group. The first group received topical insulin application while the second group had irrigation by normal saline. The macroscopic outlook, collagen production, and wound contraction rates in the animals wounds were checked at the end of day 20. The rate of wound closing was found to be higher in the topical insulin group than the NS group at all times. Further, the period of complete wound closing was shorter than the insulin group. Histopathological analysis revealed that the ulceration and inflammation were localized in the subepithelial field in the skin cross-sections of the insulin group and that there was a significant increase in collagen bundles. Thus, we think that insulin can be an alternative to normal saline application specifically in chronic wounds related to diabetes and post-op wound care.Öğe The Effects of Topical Insulin Application on Wound Healing(Modestum Ltd, 2015) Kargin, Suleyman; Tastekin, Didem; Kilic, Kemal; Cezik, Azamet; Cakir, Murat; Kucukkartallar, Tevfik; Kokbudak, NaileThe process of wound healing is a dynamic event during which the stages of fibroplasia, angiogenesis, and re-epithelization perfectly take place.

We investigated the effects of collagenase on the debridement of experimental pancreatic necrosis. The study covered 4 groups; each group had 10 rats. Group I was the necrotizing pancreatitis group. Group II was the collagenase group with pancreatic loge by isotonic irrigation following necrotizing pancreatitis. Group III was the collagenase group with pancreatic loge following necrotizing pancreatitis. Group IV was the intraperitoneal collagenase group following necrotizing pancreatitis. The progress of the groups was compared hematologically and histopathologically. There was no difference among the groups regarding the levels of leukocyte, hemogram, and urea. The differences in AST levels between Group I and II; and differences in glucose, calcium, LDH, AST, and amylase between Group II and III; between Group II and IV; between Group I and III; and between Group I and IV were statistically significant (P < 0.05). There were statistically significant differences between Group II and III, and Group II and IV regarding edema, acinar necrosis, inflammatory cell infiltration, hemorrhage, and fat necrosis (P < 0.05). In conclusion, the collagenase preparation used in this experimental pancreatitis model was found to be effective in the debridement of pancreatic necrosis.Öğe Fulminant Liver Failure Due to Amanita Phalloides Toxicity Treated with Emergent Liver Transplantation(Modestum Ltd, 2015) Gok, Funda; Topal, Ahmet; Hacibeyoglu, Gulcin; Erol, Atilla; Biyik, Murat; Kucukkartallar, Tevfik; Yosunkaya, AlperThe clinical picture secondary to amanita phalloides, which began with gastrointestinal complaints, advanced to fulminant hepatic failure in two days. Emergency liver transplantation was decided for the case of a 48-year-old male patient, who at the same time had renal failure and acute pancreatitis. Bridge treatment with plasma diafiltration was applied until the liver transplantation, which was successfully performed on the fifth day of admission to the hospital. Acute pancreatitis and renal failure also resolved and the patient was discharged in a healthy condition on the 30th day of admission. The timing of the transplant in fulminant liver failure and criteria used to select the timing are particularly important. Transplantation should be performed not too early, nor too late. In addition, the development of multiple organ failure during the period until transplantation may result in the death of the patient. Therefore, extra corporeal liver support systems are suggested as an important treatment tool at this stage.Öğe Fulminant Liver Failure Due to Amanita Phalloides Toxicity Treated with Emergent Liver Transplantation(Modestum Ltd, 2015) Gok, Funda; Topal, Ahmet; Hacibeyoglu, Gulcin; Erol, Atilla; Biyik, Murat; Kucukkartallar, Tevfik; Yosunkaya, AlperThe clinical picture secondary to amanita phalloides, which began with gastrointestinal complaints, advanced to fulminant hepatic failure in two days.

We herein present the case of a 55-year-old male patient diagnosed with gastric necrosis and perforation caused by acute gastric dilatation. Since the stomach has a rich blood circulation, necrosis and perforation are rarely seen. Clinically, more than 90% of cases have complaints of vomiting. The most useful method in revealing the diagnosis and aetiology is computerized tomography. Medical treatment is appropriate for cases where no necrosis and peritonitis findings are detected through endoscopy. Delays in surgical treatment increase the risk of mortality.Öğe Ileosigmoidal knotting, an unusual form of acute intestinal obstruction(Wiley, 2015) Cakir, Murat; Tekin, Ahmet; Kucukkartallar, Tevfik; Kartal, AdilAimIleosigmoidal knotting is an unusual form of acute intestinal obstruction characterized by closed-loop obstruction of both ileum and sigmoid colon. We present 36 cases of ileosigmoidal knotting. MethodsA retrospective analysis was designed to examine preoperative, operative, and postoperative findings of the 36 patients with ileosigmoidal knotting who were surgically treated in Necmettin Erbakan University's Meram Medical Faculty (Konya, Turkey) throughout a 26-year period. ResultsThe mean age was 55 (range, 47-61) years. The most common symptoms were abdominal pain, distention, obstipation, and vomiting, and the most common signs were abdominal tenderness and distention. The preoperative diagnosis was acute obstructed bowel in all patients. After resuscitation, all patients underwent emergency laparotomy. The most common type of ileosigmoidal knotting was type IA, in which the active ileum encircled the passive sigmoid in a clockwise manner. There was gangrene in both ileum and sigmoid colon in all patients. All ischemic bowels including ileum and sigmoid colon were resected and the continuity was carried out using primary anastomosis or Hartmann's procedure. ConclusionsIleosigmoidal knotting is a rare disease but its preoperative diagnosis is difficult. In cases of knotting there is no form of conservative treatment. Resective surgery is absolutely necessary.Öğe Incidental Neuroendocrine Carcinoma of the Gallbladder(Modestum Ltd, 2014) Gundes, Ebubekir; Kucukkartallar, Tevfik; Cakir, Murat; Gemici, Kazim; Esen, Haci HasanGallbladder cancer is rare and adenocarcinoma usually seen. Neuroendocrine carcinomas are rare in malignancies. Generally diagnosis is not made in the pre-operative period. They are generally diagnosed after cholecystectomy through hystopathological examination. In this type of tumors primary treatment is surgical and cure can only be through a complete surgical resection. The histopathological examination of the neuroendocrine carcinoma after laparoscopic cholecystectomy in a patient wanted to present the report. This is about the treatment of cancers, certain drugs used for chemotherapy after surgery. The patient's 32-month follow-up of any problems encountered.Öğe Incidental Neuroendocrine Carcinoma of the Gallbladder(Modestum Ltd, 2014) Gundes, Ebubekir; Kucukkartallar, Tevfik; Cakir, Murat; Gemici, Kazim; Esen, Haci HasanGallbladder cancer is rare and adenocarcinoma usually seen.

This study aims to explore the usage of intraocular pressure measurements as the early indicator of the increase in intra-abdominal pressure. Methods. In this prospective study, 40 patients undergoing elective surgery were included. Patients were divided into four groups of 10 patients. The control group (Group C) was not subjected to laparoscopic intervention. Laparoscopic surgery was, respectively, performed with an intra-abdominal pressure of 9, 12, and 15 mmHg in Groups L (low), M (medium), and H (high pressure). Intraocular pressure was measured binocularly in each patient at three different times (before, during, and end of surgery) using a contact tonometer. Results. Patients' gender, age, body mass index (BMI), American Society of Anesthesiology (ASA) class, and operative times were not different among the groups. No complications occurred with either the surgery or measurement of intraocular pressure. Intubation was associated with a severe rise in IOP (P < 0.05). An increase in intraocular pressure was seen in groups M and H (P < 0.05). Conclusion. Intraocular pressure was increased in the groups with an intra-abdominal pressure of 12 mmHg or more. Measuring the intraocular pressure might be a useful method to estimate the intra-abdominal pressure.Öğe Investigation of the effect of ultrasonography-guided bilateral erector spinae plane block on postoperative opioid consumption and pain scores in patients undergoing hepatectomy: a prospective, randomized, controlled study(Associacao Paulista Medicina, 2022) Hacibeyoglu, Gulcin; Topal, Ahmet; Kucukkartallar, Tevfik; Yilmaz, Resul; Arican, Sule; Uzun, Sema TuncerBACKGROUND: There is still a debate about what constitutes effective and safe postoperative analgesia in hepatectomy surgery. Erector spinae plane (ESP) block may be an important part of multimodal analgesia application in hepatectomy surgery. OBJECTIVES: To compare the effects of ultrasound-guided bilateral erector spinae plane block combined with intravenous (iv) patient-controlled analgesia (iv PCA), in comparison with iv PCA alone, in hepatectomy surgery. DESIGN AND SETTINGS: Randomized prospective single-blinded study in a tertiary university hospital. METHODS: Fifty patients scheduled for elective hepatectomy surgery were included in the study. Patients were randomized into the ESP group or the control group. In the ESP group, bilateral ESP block was performed preoperatively and iv PCA was used. In the control group, only iv PCA was used. Numerical rating scale (NRS) scores at rest and coughing, analgesic requirements and occurrences of nausea and vomiting were recorded. RESULTS: Intraoperative and postoperative opioid consumption, rescue analgesia requirement and resting and dynamic NRS scores were significantly lower in the ESP group (P < 0.05). There was no significant difference between two groups in terms of the presence of dynamic pain after the first postoperative hour. While all patients in the control group had nausea and vomiting, 24% of the patients in the ESP group did not have nausea and vomiting. CONCLUSION: This study showed that ESP block can be used as a part of multimodal analgesia, with the benefit of reducing opioid consumption and postoperative nausea and vomiting in hepatectomy surgery.Öğe Investigation of the effect of ultrasonography-guided bilateral erector spinae plane block on postoperative opioid consumption and pain scores in patients undergoing hepatectomy: a prospective, randomized, controlled study(Associacao Paulista Medicina, 2022) Hacibeyoglu, Gulcin; Topal, Ahmet; Kucukkartallar, Tevfik; Yilmaz, Resul; Arican, Sule; Uzun, Sema TuncerBACKGROUND: There is still a debate about what constitutes effective and safe postoperative analgesia in hepatectomy surgery.

The aim of our study is to discuss the artery anomalies we detected in renal transplantation cases in our clinic in line with the relevant literature. Materials and Methods: Five (39%) of the patients were female, 8 were male (61%) and their mean age was 43.7 (22-73), mean follow-up period was 30.5 months (4 to 90). For 7 of the patients, the organs were transplanted from a cadaver and 6 were transplanted from living donors. 12 patients had double, 1 patient had three renal arteries. Six patients were given ex vivo pant type side by side reconstruction to obtain a single large artery and the external iliac was anastomosed to the artery. In 1 patient with a small inferior polar artery, the inferior polar artery was ligated. In 1 patient, the arteries were positioned by in situ anastomosis one by one. In one patient with three arteries, the upper arteries were positioned by pant type anastomosis and anastomosed as a single artery, and the lower polar artery was anastomosed with the inferior epigastric artery end to end. Results: In four patients (30.7%) there was delayed graft function, 1 patient (7.6%) developed acute rejection verified with biopsy. In the post-operative period, it was determined that 3 patients had lymphocele which did not require intervention, 1 patient had subcutaneous infection and 1 patient had perirenal hematoma. Subcutaneous infection recovered with antibiotic treatment. As for the patient with perirenal hematoma, the perirenal hematoma resorbed spontaneously. Conclusion: Using kidneys with multiple renal arteries for transplantation brings with it some theoretical risks. Tubular necrosis, delayed graft function and rejection can be seen more frequently due to elongated cold or hot ischemia time. We are of the opinion that large and single renal artery anastomosis obtained with ex vivo pant anastomosis application can decrease the vascular complication risk in multiple renal artery.Öğe Our Primary Colorectal Lymphoma Experiences(Galenos Yayincilik, 2014) Gundes, Ebubekir; Cakir, Murat; Kucukkartallar, Tevfik; Tasci, Halil Ibrahim; Tekin, Ahmet; Tekin, SakirAim: In this paper, we aimed to present our surgical approach to ten patients who underwent surgery for primary colonic lymphoma and the features and clinical presentations of the tumors. Methods: We retrospectively analyzed the data of ten patients who underwent surgery in our clinic for primary colorectal lymphoma between January 2006 and December 2012. Results: The median age of the patients at the time of diagnosis was 66 (50-84) years. The most frequent presenting complaints were abdominal pain and change in bowel habits. The most frequent physical examination findings were abdominal distention and widespread tenderness. Three patients underwent emergency surgery subsequent to acute abdomen diagnosis. During the surgery, it was observed that one patient had ileocecal invagination, one patient had a mass that caused cecal perforation, and one other had an obstructive mass in the sigmoid colon. The most common localizations were the cecum (60%), sigmoid colon (30%), and the rectum (10%), respectively. The most frequent type was B- cell lymphoma (n=8). Conclusion: Primary colonic lymphoma is a rare condition. It is still yet uncertain whether surgery or chemotherapy should be advised first.
