Article An Analysis of 13 Patients With Perforated Gastric Carcinoma: a Surgeon's Nightmare(Bmc, 2008) Kotan, Cetin; Sumer, Aziz; Baser, Murat; Kiziltan, Remzi; Carparlar, M. AliBackground and Objectives: Perforation is a rare complication of gastric carcinoma and generally not diagnosed preoperatively. To clarify the clinicopathologic characteristics of patients with this condition we reviewed 13 cases of gastric cancer perforation who required emergency surgery. Methods: A total of 13 patients with gastric cancer perforation were retrospectively reviewed. The clinicopathological features including tumor stage and survival and also the type of treatment were analyzed and compared to literature data. Results: There were 13 patients (10 males and 3 females) with a mean age of 59.0 +/- 9.56 years. The incidence of perforated gastric cancer was 9.6% among gastric carcinoma and 4.2% of all gastric perforation cases. The perforation was more frequently in stage III-IV (2-10), but one case of stage II (T3N0M0) gastric cancer was also observed. None of the patients had curative resection or radical lymph-node dissection. Six (46%) patients were treated by palliative, local surgery. Emergency gastrectomy were performed in 7 (54%) patients. Overall 30-day mortality rate was % 46. The overall survival time was 128.2 +/- 184.8 days for all patients, it was 52.8 +/- 52.9 days for locally treated group, and 192.9 +/- 235.4 days for patients who underwent resectional surgery. The difference between the treatment groups was not significant Conclusion: Perforation usually occurs in advanced stages of gastric cancer. These patients had a poor prognosis because of the presence of advanced cancer.Article Bronchogenic Cyst Mimicking an Adrenal Mass in the Retroperitoneal Region: Report of a Rare Case(Wolters Kluwer Medknow Publications, 2015) Bulut, Gulay; Bulut, Mehmet Deniz; Bahadir, Inci; Kotan, CetinWe report the surgical excision of a retroperitoneal bronchogenic cyst that presented as a nonfunctioning left adrenal mass in a 25-year-old woman with continuous pain in the left flank. Preoperative biochemical testing confirmed that the mass was nonfunctional. Bronchogenic cysts are mostly benign congenital abnormalities that originate from the remnants of the primitive foregut and typically occur in the lung. Subdiaphragmatic and especially, retroperitoneal locations are rare. Despite the rarity of this pathologic entity, bronchogenic cysts should be considered in the differential diagnosis of retroperitoneal cystic lesions. Diagnosis must be definitively confirmed by histology.Article Colon Cancer Presented With Sigmoid Volvulus: a Case Report(Elsevier Sci Ltd, 2015) Aras, Abbas; Kiziltan, Remzi; Batur, Abdussamet; Celik, Sebahattin; Yilmaz, Ozkan; Kotan, CetinIntroduction: Sigmoid volvulus is the most prevalent type of colonic volvulus. Colon cancer is seen less where sigmoid volvulus is common, so it is rare to see that colon cancer is synchronous with sigmoid volvulus. PRESENTATION OF CASE: We would like to present a case of sigmoid volvulus caused by colon cancer in a male patient aged 80 who was referred to the hospital with toxaemic shock presentation. DISCUSSION: Sigmoid cancer can be presented as sigmoid volvulus to the emergency department. In intestinal obstruction early diagnosis is of crucial importance. Computarized tomography is a diagnosis tool that should be preferred both in the diagnosis of obstruction and in detecting its cause, localisation, degree and complications. CONCLUSION: When surgery is performed due to the urgent colonic obstruction in colonic volvulus diagnosed patients, a colon tumour should be considered in the same column loops or in the distal colon. We believe that CT is the method that should be preferred in large-bowel obstruction suspected patients. (C) 2015 The Authors.

Methods: Forty Wistar albino rats weighing 250-300 g were randomly divided into four groups (10 rats/group). Group 1 (control group) rats were not administered Thymoquinone (TQ) for 3 days after the operation. Group 2 was administered daily TQ for 3 days starting from the first day after the operation. Group 3 was not administered TQ for 7 days after the operation. Group 4 was administered daily TQ for 7 days starting from the first day after the operation. Thymoquinone was administered as a single dose oral gavage through a 4F feeding catheter per each day. The bursting strength of the anastomosis was measured on 3rd and 7th postoperative days (POD) and resection was performed. Subsequently, the hydroxyproline level in the resected tissue was measured and a histological evaluation was performed. Results: The bursting pressures of the anastomoses were measured to be statistically significantly greater on 7th POD in TQ administered groups compared to those without TQ administration. Tissues were stained with Masson's trichrome dye in order to evaluate the amount of fibrous tissue reaction for histopathological examination; there was no significant difference in the amount of fibrous tissue between groups 1 and 2, while a very marked increase in the fibrous tissue was detected in groups 3 and 4. Mean tissue hydroxyproline levels of the groups 3 and 4 on 7th POD were 1.30 and 2.72 mu g/g-protein, respectively. The difference between the groups was statistically significant (p = 0.001). Conclusions: TQ significantly increased the bursting pressure of the anastomosis, tissue hydroxyproline level, and fibrous tissue production.Article Gall Bladder Perforation, a Rare Complication of Continuous Ambulatory Peritoneal Dialysis: Case Report(Turk Nefroloji Diyaliz Transplantasyon dergisi, 2007) Sayarlioglu, Hayriye; Soyoral, Yasemin; Dogan, Ekrem; Kotan, Cetin; Asian, Murat; Baser, Murat; Erkoc, RehaContinuous ambulatory peritoneal dialysis (CAPI2b is a widely used method al the treatment of end stage Fero' failure patients, Mechanical and meoholo cornplications can be detected during CAPD treatment.

Ali; Uslukaya, Omer; Bayrak, Vedat; Kotan, Cetin; Kemik, Ozgur; Iliklerden, UmitWe report on a case of gossypiboma. A 54-year-old woman was admitted to our hospital with abdominal mass. She had undergone a caesarean operation 23 years previously. The mass in the right abdominal quadrant was suspected by abdominal computed tomography and magnetic resonance imaging. The mass was removed by laparotomy excision and the final diagnosis was gossypiboma.Article Impaired Function of the Levator Ani Muscle in the Grand Multipara and Great Grand Multipara(Tohoku Univ Medical Press, 2006) Kisli, Erol; Kisli, Mesude; Agargun, Havva; Altinokyigit, Filiz; Kamaci, Mansur; Ozman, Ekrem; Kotan, CetinRepeated deliveries might disturb the levator function and increase defecation disorders. In this prospective study, we determined the electric activity of the levator ani muscle (LAM) in nullipara, multipara, grand multipara, and great grand multipara (20 subjects for each group). Multiparity, grand multiparity, and great grand multiparity were defined as women having 2 - 5, 6 - 9, and 10 and over deliveries, respectively. The number of deliveries of multipara, grand multipara and great grand multipara were 4.05 +/- 1.14 (2 - 5), 7.55 +/- 1.23 (6 - 9) and 12.2 +/- 2.16 (10 - 17), respectively. All women were asked whether they had experienced constipation, fecal or urinary incontinence, and/or pelvic pain. All women were also evaluated for pelvic organ prolapse. Electromyography (EMG) of the LAM at rest and on contraction was recorded. EMG is an electrical recording of muscle activity. Constipation, incontinence and pelvic organ prolapse were encountered in multipara, grandmultipara and great grand multipara women. The LAM EMG at rest and on contraction in the nullipara was accepted as control. Both the resting and contractile activities of the LAM were as follows: nullipara > multipara > grand multipara > great grand multipara. These findings indicate that levator dysfunction and defecation disorders are increased with repeated deliveries because of pudendal and/or levator ani nerve injury and traumatic injury to the LAM occurred with the mechanical stresses of vaginal deliveries.Article Ingested Intraabdominal Foreign Bodies That Require Surgical Intervention(Turkish Assoc Trauma Emergency Surgery, 2016) Kiziltan, Remzi; Yilmaz, Ozkan; Aras, Abbas; Toktas, Osman; Batur, Abdulsamet; Agar, Fatma; Kotan, CetinBACKGROUND: The aim of the present study was to review cases that required surgical intervention to remove ingested foreign bodies. METHODS: Medical records of 7 patients who underwent surgical intervention at the Yuzuncu Yil University Department of General Surgery between 2009 and 2014 after ingesting foreign bodies were reviewed. RESULTS: Female: male ratio was 5:2; mean age was 25 (16-35). Four patients had swallowed pins, 1 patient had swallowed a sewing pin, 1 patient had swallowed a safety pin, and 1 patient had swallowed a wristwatch. The patient who had swallowed the wristwatch had psychiatric disorders. All other patients stated that they had swallowed the objects by accident. CONCLUSION: Most ingested foreign bodies pass smoothly through the gastrointestinal (GI) tract within a week, but those that migrate out of the lumen require surgical intervention due to complications including perforation, abscess, fistula, and peritonitis. Early diagnosis and intervention is crucial to reduce morbidity and mortality. It is believed that sharp and pointed objects that migrate outside of the lumen ought to be removed, lest they cause complications.Article Levels of Matrix Metalloproteinase-1 and Tissue Inhibitors of Metalloproteinase-1 in Gastric Cancer(Baishideng Publ Grp Co Ltd, 2011) Kemik, Ozgur; Kemik, Ahu Sarbay; Sumer, Aziz; Dulger, Ahmet Cumhur; Adas, Mine; Begenik, Huseyin; Kotan, CetinAIM: To evaluate the levels of preoperative serum matrix metalloproteinase-1 (MMP-1) and tissue inhibitor of metalloproteinase-1 (TIMP-1) in gastric cancer. METHODS: One hundred gastric cancer patients who underwent gastrectomy were enrolled in this study. The serum concentrations of MMP-1 and TIMP-1 in these patients and in fifty healthy controls were determined using an enzyme-linked immunosorbent assay. RESULTS: Higher serum MMP-1 and TIMP-1 levels were observed in patients than in controls (P < 0.001). Serum MMP-1 and TIMP-1 levels were positively associated with morphological appearance, tumor size, depth of wall invasion, lymph node metastasis, liver metastasis, perineural invasion, and pathological stage. They were not significantly associated with age, gender, tumor location, or histological type. CONCLUSION: Increased MMP-1 and TIMP-1 were associated with gastric cancer. Although these markers are not good markers for diagnosis, these markers show in advanced gastric cancer. (C) 2011 Baishideng.

Deep venous thrombosis is a common condition that affects more than 250 000 patients each year in the United States. In spite of limitations of the available diagnostic tools for detecting deep venous thrombosis, laboratory tests such as plasma D-dimer has been gained much interest recently. So, we aimed to investigate the D-dimer and all hemostatic factors in patients with deep vein thrombosis. Material and Methods: We investigated the levels of the D-dimer and Von Willebrand factor by enzyme linked immunosorbent assay (ELISA) in 120 patients with deep venous thrombosis and in 115 patients without deep venous thrombosis. We used standard methods for detecting the levels of the cholesterol, creatinin, INR, factor VIII: C ratio, and aPTT. We used Clauss method for detecting the fibrinogen levels. Results: We obtained important results in patients with deep venous thrombosis compared to in patients without deep vein thrombosis. Age, BMI, aPTT, INR, and total cholesterol levels were not found statistically differences in patients with deep venous thrombosis (p> 0,05). Plasma D-dimer, creatinin, factor VII: C, and Von Willebrand factor levels were found higher in patients with deep venous thrombosis than in patients without deep venous thrombosis (respectively, p<0,001, p<0,01). But, plasma fibrinogen levels were not found lower in patients with deep venous thrombosis (p<0,01). Conclusion: In conclusion, we suggested that the plasma D-dimer and hemostatic factor levels may play an important role in diagnosis and treatment of deep venous thrombosis.Article Outcome of Surgical Treatment of Intestinal Perforation in Typhoid Fever(Baishideng Publishing Group inc, 2010) Sumer, Aziz; Kemik, Ozgur; Dulger, Ahmet Cumhur; Olmez, Aydemir; Hasirci, Ismail; Kisli, Erol; Kotan, CetinAIM: To represent our clinical experience in the treatment of intestinal perforation arising from typhoid fever. METHODS: The records of 22 surgically-treated patients with typhoid intestinal perforation were evaluated retrospectively. RESULTS: There were 18 males and 4 females, mean age 37 years (range, 8-64 years). Presenting symptoms were fever, abdominal pain, diarrhea or constipation. Sixteen cases were subjected to segmental resection and end-to-end anastomosis, while 3 cases received 2-layered primary repair following debridement, one case with multiple perforations received 2-layered primary repair and end ileostomy, one case received segmental resection and end-to-end anastomosis followed by an end ileostomy, and one case received segmental resection and end ileostomy with mucous fistula operation. Postoperative morbidity was seen in 5 cases and mortality was found in one case. CONCLUSION: Intestinal perforation resulting from Salmonella typhi is an important health problem in Eastern and Southeastern Turkey. In management of this illness, early and appropriate surgical intervention is vital. (C) 2010 Baishideng.

Atherosclerosis remains the most common etiologic factor, accounting for more than two-thirds of the cases reported. Other etiologies include carcinoma, ulcers, radiation, aortitis and foreign bodies including sewing needle, cocktail stick, open safety pin and fishbone. We report a case of a 17 year-old girl who underwent surgical treatment because of severe upper gastrointestinal bleeding which was related to an aortoduodenal fistula caused by a swallowed sewing needle. At operation, a chronic aortoduodenal fistula that contained the sewing needle was found and repaired. This is the fourth case in the literature in which a needle was found to be associated with the development of an aortoenteric fistula.Article Prognostic Significance of Neutrophil-To Ratio in Esophageal Squamous Cell Carcinoma(Kare Publ, 2021) Sakin, Aysegul; Alay, Murat; Sahin, Suleyman; Aydemir, Ozan; Aldemir, Mehmet Naci; Sakin, Abdullah; Kotan, CetinOBJECTIVE: The purpose of the study was to assess the effect of neutrophil-to-lymphocyte ratio (NLR) on recurrence and survival in patients with Esophageal Squamous Cell Carcinoma (ESCC) undergoing surgery. METHODS: This was a retrospective analysis of the 80 resectable ESCC patients who underwent surgery at Yuzuncu Yil University Faculty of Medicine between 2008 and 2018. Receiver operator characteristics curve of NLR was plotted for disease-free survival (DFS). The area under the curve of NLR was 0.692 (p=0.008) with 65.2% sensitivity and 2.8 with 69.5% specificity. Patients were divided into two groups based on the NLR as follows: NLR <2.8 and NLR >= 2.8. RESULTS: Among 80 ESCC patients, 54 (65.5%) were female. The median age was 55 years (range, 26-77). The NLR was <2.8 in 47 (58.7%) patients. Median DFS was 55 months in patients with NLR >= 2.8, whereas it was not reached in those with NLR <2.8 (p=0.008), with corresponding overall survival (OS) durations of 71 months and not reached (p=0.027). Eastern Cooperative Oncology Group performance score 2, presence of obstruction at diagnosis, lower 1/3 esophageal localization, neoadjuvant treatment, and NLR >= 2.8 were found to be the factors related to survival. CONCLUSION: The present study demonstrated that high pre-treatment NLR was associated with worse DFS and OS in patients with resectable esophageal cancer. We believe that pre-treatment NLR may help guide predicting treatment outcomes in non-metastatic resectable ESCC patients.Article A Rare Complication of Biliary Stent Migration: Small Bowel Perforation in a Patient With Incisional Hernia(Hindawi Ltd, 2015) Yilmaz, Ozkan; Kiziltan, Remzi; Aydin, Oktay; Bayrak, Vedat; Kotan, CetinEndoscopic biliary stents have been recently applied with increasing frequency as a palliative and curable method in several benign and malignant diseases. As a reminder, although most of the migrated stents pass through the intestinal tract without symptoms, a small portion can lead to complications. Herein, we present a case of intestinal perforation caused by a biliary stent in the hernia of a patient with a rarely encountered incarcerated incisional hernia.Article The Relationship Between Eating and Lifestyle Habits and Cancer in Van Lake Region: Another Endemic Region for Esophageal and Gastric Cancers(Hindawi Ltd, 2015) Celik, Sebahattin; YJlmaz, E. Murat; Ozden, Ferhat; Kotan, Cetin; Okut, HayrettinPurpose. To examine the relationship between esophageal and gastric cancers commonly seen in Van Lake region and the traditional eating habits of the geography. Materials and Methods. Esophageal and gastric cancer cases, who underwent surgery between January 1, 2012, and December 31, 2013, were examined. Pathology reports of the patients and presence of Helicobacter pylori (HP) were recorded. Surveys were filled by face to face meeting or telephone call. Control group was created with randomly selected individuals without any cancer diagnosis having age, gender, and socioeconomic characteristics similar to patient group. All data were analyzed using SAS. 9.3 statistical programme. Results. Compared with the control group, herby cheese consumption (a component of eating habits) and smoking were significantly higher in the patient group (P < 0.001). Tandoor exposure is compared in terms of female gender, and significant difference was found between the groups (P = 0.0013). As a result of the analysis with logistic regression more than 150 gr of herby cheese consumption per day was found to increase the cancer risk (odds ratio 1.017; 95% CI: 1.012-1.022). Conclusion. A high consumption of herby cheese, cooking bread on tandoor, and heavy smoking were seen to be important risk factors for esophageal and gastric cancers.Article Serum Ykl-40 Levels in Patients With Esophageal Squamous Cell Carcinoma(Libertas Acad, 2011) Yilmaz, Ozkan; Kemik, Ozgur; Kemik, Ahu; Sumer, Aziz; Dulger, A. Cumhur; Asirci, Ismail; Kotan, CetinAims and background: YKL-40 is a glycoprotein secreted by macrophages, neutrophils and malignant tumor cells. YKL-40 is expressed and secreted by several types of tumors. The aim of this study examined the clinical usefulness of YKL-40 for detection in esophageal squamous cell carcinoma (ESCC). Methods: Using ELISA kits, we measured the concentration of YKL-40 in serum from 100 patients with ESCC and compared this concentration with healthy population. Results: We found significantly higher serum levels of YKL-40 in patients with ESCC compared to the healthy population (P < 0.0001). Conclusions: These results suggested that regarding serum YKL-40 as a tumor marker could be benefical in the early clinical diagnosis.Article Significance of Vegf and Microvascular Density in Gastric Carcinoma(H G E Update Medical Publishing S A, 2009) Kosem, Mustafa; Tuncer, Ilyas; Kotan, Cetin; Ibiloglu, Ibrahim; Ozturk, Mustafa; Turkdogan, M. KursadBackground/Aims: The aim of this study is to observe the relationship between the expression of vascular endothelial growth factor (VEGF), microvascular density (MVD) and the pathological characteristics of gastric carcinoma. Methodology: A total of 87 cases of gastric carcinomas were examined by immunohistochemical staining, using anti-VEGF and anti-CD34 antibodies. 62 out of 87 cases (71.2%). The MVD was 64.00 +/- 15.51 (mean SE) in VEGF-positive group and 48.33 +/- 12.71 in VEGF-negative group. Conclusions: The expression of VEGF is correlated with tumor angiogenesis, and VEGF plays an important role in new blood vessels formation. The expression of VEGF and MVD were closely correlated with the degree of differentiation and lymphatic metastasis, but not related to depth of cancer invasion, size of tumor, age or sex. Results: VEGF positive staining was obtained in 62 out of 87 cases (71.2%). The MVD was 64.00 +/- 15.51 (mean SE) in VEGF-positive group and 48.33 +/- 12.71 in VEGF-negative group. Conclusions: The expression of VEGF is correlated with tumor angiogenesis, and VEGF plays an important role in new blood vessels formation. The expression of VEGF and MVD were closely correlated with the degree of differentiation and lymphatic metastasis, but not related to depth of cancer invasion, size of tumor, age or sex.Article Small Bowel Obstruction Due To Mesodiverticular Band of Meckel's Diverticulum: a Case Report(Hindawi Ltd, 2010) Sumer, Aziz; Kemik, Ozgur; Olmez, Aydemir; Dulger, A. Cumhur; Hasirci, Ismail; Iliklerden, Umit; Kotan, CetinMeckel's diverticulum is the most common congenital anomaly of the small intestine. Common complications related to a Meckel's diverticulum include haemorrhage, intestinal obstruction, and inflammation. Small bowel obstruction due to mesodiverticular band of Meckel's diverticulum is a rare complication. Herein, we report the diagnosis and management of a small bowel obstruction occurring due to mesodiverticular band of a Meckel's diverticulum.Article Subrnandibular and Thyroid Gland Involvement of Hydatid Cysts: a Very Rare Association With Percutaneous Treatment(Turkish Soc Radiology, 2010) Avcu, Serhat; Unal, Ozkan; Kotan, Cetin; Ozturk, Mustafa; Ozen, OzkanA 48-year-old man who had a complaint of swelling in the left submandibular region and right side of the neck was referred to our radiology clinic for sonographic examination that revealed a type 1 hydatid cyst with a diameter of 32 mm in the left submandibular gland, and a type 3 hydatid cyst with a diameter of 33 mm in the right thyroid gland. The diagnosis was verified by computed tomography, magnetic resonance imaging, and hemagglutination tests. To the best of our knowledge, this is the second case in the literature of hydatid cysts involving both submandibular and thyroid glands. There was no abdominal, thoracic or brain involvement. The patient was a singer and did not accept surgical treatment, and percutaneous drainage with the PAIR (Puncture-Aspiration of cyst contents-Injection of hypertonic saline solution-Reaspiration) technique was performed for both cysts. There were no complications during or after the intervention. During 4 months of follow up the sizes of both cysts were decreased and the germinative membranes were shrunken, having a pseudotumor appearance. To the best of our knowledge, this is the first case in the literature that the PAIR method was applied for thyroid and submandibular gland hydatid cysts. Percutaneous treatment of thyroid and submandibular gland hydatid cysts seems to be a safe and effective procedure as a possible alternative to surgery.Article Successful Treatment of a Large Pelvic Abscess Using Intraluminal Vac: a Case Report(Premchand Shantidevi Research Foundation, 2016) Aras, Abbas; Celik, Sebahattin; Kiziltan, Remzi; Yilmaz, Ozkan; Kotan, CetinThe most feared complication of the surgical treatment of rectal cancer is anastomotic leakage, which is related to high rates of mortality and morbidity. Here, we present a patient who could not be treated with surgical drainage but treated by intraluminal Vacuum Associated Closure (VAC). A 34-year-old male patient was treated for rectal cancer by low anterior resection, colorectal anastomosis, and diverting ileostomy following neoadjuvant CRT. The patient reported with a postoperative anastomotic disruption and a large pelvic abscess. Due to the continuation of foul-smell drainage inspite of perianal incision and drainage, intraluminal VAC was applied and the pelvic abscess and the foul-smell were successfully treated. The presence of an adequate anal sphincter tonus is a disadvantage in anastomotic leakage, since it prevents the emptying of the intestinal content and also precludes the drainage of the pelvic abscess. The endoluminal application of VAC, similar to the results of application of VAC in open wounds, has been demonstrated to decrease fibrin and necrotic tissue in the pelvic cavity and increase granulation tissue. VAC, which has long been used in the treatment of open wounds, is a promising method in the treatment of large pelvic abscesses due to anastomotic leakage following rectum resection.
