Colorectal Cancer (CRC) is the third leading cause of cancer death in the world whose incidence is progressively rising in developing nations. It is treated with both chemotherapeutic and immunotherapeutic agents. Sorafenib is a broad-spectrum multikinase inhibitor proven to be effective in treating different types of carcinoma, including liver, thyroid, renal, and breast cancers. This study aimed to investigate the effect of Sorafenib against 1,2-dimethylhydrazine (DMH)-induced CRC in mice. Mice were injected with DMH (20 mg/kg) over 12 weeks to induce the cancer. Mice were treated with Sorafenib (30 mg/Kg for 5 days). Colon tissues were examined by histological analysis, and gene expression level of key players involved in the Wnt signaling pathway were assessed using RT-PCR. Our results showed that Sorafenib restored the normal histology and structure of colonic tissue. Sorafenib downregulated the expression level of Wnt5a and Cyclin D1 and upregulated that of APC, GSK-3β and β catenin compared to untreated control. In conclusion, Sorafenib inhibits DMH-induced CRC by targeting the Wnt signaling pathway. [ABSTRACT FROM AUTHOR]

OBJECTIVE: Cell adhesion and angiogenesis within the extracellular matrix involve special signaling molecules, such as integrins and the actin binding protein Talin-1. The aim of this study was to investigate and describe the expression of Talin-1 for the early detection of colon cancer. PATIENTS AND METHODS: Blood serum samples were collected from 50 healthy volunteers and from 90 patients with colon cancer. Using an enzyme-linked immunosorbent assay (ELISA), all 140 samples were analyzed. RESULTS: Preoperative levels of Talin-1 in the serum were significantly higher in patients with colon cancer (p < 0.001). No significant correlation was found between preoperative levels of Talin-1 in the serum and the age and gender of the patients (p < 0.05). However, a significant correlation was found between Talin-1 levels and the tumor grade, TNM stage, and lymph node metastasis (p < 0.001). CONCLUSIONS: Talin-1 may play a role in the reinforcement of cell proliferation, cell adhesion, and angiogenesis in colon cancer. Thus, the Talin-1 protein activity may be a novel biomarker to detect colon cancer in humans. [ABSTRACT FROM AUTHOR]

Abstract Background The splenic cysts constitute a very rare clinical entity. They may occur secondary to trauma or even being more seldom due to parasitic infestations, mainly caused by ecchinocccus granulosus. Literature lacks a defined concencus including the treatment plans and follow up strategies, nor long term results of the patients. In the current study, we aimed to evaluate the diagnosis, management of patients with parasitic and non-parasitic splenic cysts together with their long term follow up progresses. Methods Twenty-four patients with splenic cysts have undergone surgery in our department over the last 9 years. Data from eighteen of the twenty-four patients were collected prospectively, while data from six were retrospectively collected. All patients were assessed in terms of age, gender, hospital stay, preoperative diagnosis, additional disease, serology, ultrasonography, computed tomography (CT), cyst recurrences and treatment. Results In this study, the majority of patients presented with abdominal discomfort and palpable swelling in the left hypochondrium. All patients were operated on electively. The patients included 14 female and 10 male patients, with a mean age of 44.77 years (range 20–62). Splenic hydatid cysts were present in 16 patients, one of whom also had liver hydatid cysts (6.25%). Four other patients were operated on for a simple cyst (16%) two patients for an epithelial cyst, and the last two for splenic lymphangioma. Of the 16 patients diagnosed as having splenic hydatit cysts, 11 (68.7%) were correctly diagnosed. Only two of these patients were administered benzimidazole therapy pre-operatively because of the risk of multicystic disease The mean follow-up period was 64 months (6–108). There were no recurrences of splenic cysts. Conclusion Surgeons should keep in mind the possibility of a parasitic cyst when no definitive alternative diagnosis can be made. In the treatment of splenic hydatidosis, benzimidazole therapy is not necessary, although it is crucial to perform splenectomy without rupturing and spilling the cysts.

Abstract Diverticulum of the cecum is a rare, benign, generally asymptomatic lesion that manifests itself only following inflammatory or hemorrhagic complications. Most patients with inflammation of a solitary diverticulum of the cecum present with abdominal pain that is indistinguishable from acute appendicitis. The optimal management of this condition is still controversial, ranging from conservative antibiotic treatment to aggressive resection. We describe four cases that presented with symptoms suggestive of appendicitis, but were found at operation to have an inflamed solitary diverticulum.

Objective: To determine the associated risk factors for isolated liver metastasis in breast cancer patients and to detect the prognostic factors related to survival., Study Design: Analytical study. Place and Duration of the Study: Department of General Surgery, The University of Health Sciences, Istanbul, Turkiye, from January 2011 to November 2020., Methodology: Patients with breast cancer liver metastasis who experienced surgery were retrospectively analysed for breast cancer and metastases-related characteristics. Descriptive statistical methods were used in the evaluation of data. Survival analyses were estimated by the Kaplan-Meier method. Log-rank and univariable Cox regression tests were utilised to search for prognostic factors' impact on survival., Results: Out of 12 patients, 11 had recurrent disease after a median of 36 months of disease-free survival (DFS) and one patient had de novo metastasis. Grade 3 tumours and increased expression of Ki-67 had a negative effect on DFS. The median follow-up period was 66 months. Survival analysis showed 2- and 3-year progression-free survival (PFS); overall survival rates were 82%, 69%, 92%, and 82%, respectively. Development of liver metastasis in 3 years following breast cancer treatment was linked to worse PFS (p = 0.040)., Conclusion:  Long-term survival is possible for breast cancer survivors with liver metastasis. Disease-free interval is an important determinant. Longer progression-free survival was detected in patients who had developed metastasis after three years of breast cancer treatment., Key Words: Breast cancer, Liver metastasis, Hepatic surgery.

Objectives: The exact mechanism that causes the neurotoxicity of hepatic encephalopathy (HE) is still unknown. In this retrospective study, we aimed to define the frequency of hyperammonemia and its relationship with HE., Methods: The records of 190 patients who were followed up in the Organ transplantation and Hepato-pancreato-biliary surgery intensive care unit (ICU) between August 2021 and August 2022 were reviewed retrospectively. 111 adults and children whose ammonia levels were examined during their stay in the ICU were included in the study He was evaluated with West Haven Criteria. HE had grades 0-4 in the groups., Results: The median age (range) was 5 (0-16) children and 60 (20-104) adults. The median ammonia value (range) was 42,2 (16-314). Hyperammonemia was present in 39 patients (35%) of all patients. Patients with hyperammonemia and grade 0 encephalopathy were 16 (14%), grade 1-2 patients were 11(10%), and grade 3 patients were 12 (11%)., Conclusion: While our findings and literature evidence strongly support the view that ammonia is the primary factor responsible for, HE development, it shows that factors other than ammonia can only exacerbate HE. In addition, we think that the increased ammonia value in patients with acute liver failure and acute on chronic liver failure is correlated with the increase in the degree of encephalopathy., Competing Interests: None declared., (©Copyright 2023 by The Medical Bulletin of Sisli Etfal Hospital.)

Objectives: 18 F-fluorodeoxyglucose (FDG)-positron emission tomography/computed tomography (PET/CT) is a useful staging method in pancreatic cancer. The prognosis of pancreatic adenocarcinoma is affected by the tumor stage and resectable state. Maximum standardized uptake value (SUV max ), metabolic tumor volume (MTV), and total lesion glycolysis (TLG) of primary tumors are related to prognostic parameters in pancreatic cancer. This study compared 18 F-FDG PET/CT findings with prognostic factors and overall survival of patients with pancreatic cancer., Methods: Patients with pancreatic adenocarcinoma, referred to our department between 2015 and 2022 for staging, were retrospectively evaluated. Head-to mid-thigh PET/CT images were obtained 1 h after 18 F-FDG injection. Demographic data, survival, and clinical and pathological findings of 39 patients, who underwent surgery after PET/CT imaging, were collected. All primary tumor MTV, SUV max , background SUV max , and TLG data have were measured., Results: The images of 39 patients (24 women and 15 men) with a mean age of 66.62±9.60 years were evaluated. The mean SUV max , MTV 40%, and TLG of the primary tumors in the pancreatic tissue were 6.28±2.33, 19.33±9.77, and 66.56±45.99, respectively. The average survival after disease diagnosis was 18.97±11.47 (2-55) months. MTV and TLG were significantly higher in patients who died during our study. SUV max has a significant effect on mortality., Conclusion: 18 F-FDG PET/CT metabolic parameters of SUV max , MTV, and TLG could help predicting the prognosis of pancreatic cancer preoperatively and follow-up in patients with resectable tumors. Additionally, in our study group tumor grade and perineural invasion significantly affected overall survival., Competing Interests: Conflict of Interest: No conflict of interest was declared by the authors., (©Copyright 2023 by Turkish Society of Nuclear Medicine Molecular Imaging and Radionuclide Therapy published by Galenos Yayınevi.)

Objective: Transarterial radioembolisation (TARE) is a promising technique for unresectable primary tumours of the liver. We present our clinical experience and the response to treatment and survival data of patients with hepatocellular carcinoma (HCC) who were treated with Y-90 radioembolisation in our hospital's angiography department., Material and Methods: The data of all the patients with HCC referred to our department for Y-90 treatment were analysed retrospectively. The patients were selected according to the treatment protocol criteria, and lung shunt fraction was evaluated using macroaggregated albumin scintigraphy before radioembolisation. Patients with compatible blood tests and lung shunt fraction rates were chosen for treatment with Y-90 TARE., Results: Twenty-four patients were suitable for Y-90 treatment. The patients were treated with 137 ± 44.6 (80-245) Gy Y-90 glass microspheres. The treatment results were evaluated using modified RECIST criteria, and the partial response, complete response, stable disease and progression rates were found to be 54.2, 16.7, 20.8 and 8.3%, respectively. The median survival rate following treatment was 10 months. Higher alpha-fetoprotein (AFP) levels were related to decreased survival, and posttreatment AFP levels had a significant effect on mortality rates. Higher survival rates were detected in the patients who were treated more selectively than the group treated via a lobar approach., Conclusion: Y-90 microsphere radioembolisation is a safe method and may be helpful in treating patients with unresectable hepatocellular tumours. More favourable results were obtained in the patients treated using the more selective approach. AFP levels before and after treatment could predict survival rates., (Copyright © 2021 Wolters Kluwer Health, Inc. All rights reserved.)

The morphological distinction between the various types of mucinous ovarian tumors has major prognostic implications but may be challenging. The aims of our study were to describe inter-observer reproducibility in the morphological diagnosis of mucinous ovarian tumors, to evaluate the clinical relevance of possible diagnostic discrepancies, and to identify molecular abnormalities correlated with the histological type. Seventy-nine ovarian mucinous borderline tumors (MOB) and either expansile or infiltrative carcinomas (MOC) were independently reviewed by two gynecological pathologists. Molecular analysis was performed in 32 cases. Concordance between the two pathologists was reached in 67 cases (k: 0.78). The main discrepancies (8/12) were the evaluation of nuclear grade 3 or that of microfoci (< 5 mm) of infiltrative-type carcinoma in an otherwise typical expansile MOC. Our follow-up analysis showed that infiltrative MOC had a lower overall survival (OS) (p < 0.0024) and progression-free survival (PFS) (p = 0.0060) as compared with MOB and expansile MOC. The presence of nuclear grade 3 or microfoci (< 5 mm) of infiltrative-type pattern of invasion in an otherwise typical expansile MOC did not alter the prognosis as compared with expansile MOC without these features, in terms of OS (p < 0.0028) and PFS (p = 0.0074). KRAS mutations were more frequent in MOB (71%), than in expansile (50%) and infiltrative MOC (14%). In contrast, the prevalence of TP53 mutation was lower in MOB (43%), than in expansile (58%) and infiltrative MOC (71%). Our results confirm that in MOC, the expansile pattern of invasion is associated with a better prognosis than extensive (> 5 mm) infiltrative-type pattern of invasion. No specific or sensitive molecular profile might help in the differential diagnosis of mucinous ovarian tumors.

Introduction: Xanthogranulomatous cholecystitis (XGC) is a rare inflammatory disease of the gallbladder (GB). XGC surgery is a difficult process due to its clinical, radiological, and intraoperative findings. In this study, our aim is to show the difficulties of XGC surgery and to find out if laparoscopic surgery is a sufficient procedure. Materials and Methods: Histological findings of 3339 cholecystectomy patients, who were operated between January 2015 and January 2020, were retrospectively reviewed. Age, gender, radiological results, clinical features, intraoperative findings, and surgical management of the patients with XGC were recorded. Results: XGC was observed in 70 patients (2.09%). The average age was 53.75. M:F ratio was 1.2. In radiological examinations, gallstones were found in 94.2% of the patients and GB wall thickness (≥3 mm) was increased in 58.5% of the patients. Around 45.7% of the patients came to the clinic with chronic cholecystitis and 32.9% with acute cholecystitis. In the intraoperative period, adhesions were observed in 80% and increase in GB wall thickness was observed in 77.1% of the patients. The operation started laparoscopically in 66 patients. In 14 patients (21.2%), it was converted to open surgery usually due to insufficient dissection of Calot's triangle. Gallbladder carcinoma (GBC) was suspected in 6 patients, but none of them had malignancy in frozen sections or histology. Conclusions: XGC surgery is difficult due to its radiological, clinical, and intraoperative features and mimicking GBC. It can be converted to open cholecystectomy due to difficulties in laparoscopic dissection. However, since conversion cholecystectomy rates are reasonable, laparoscopic surgery is recommended in patients with suspected XGC.

The thyroid is an unusual site for metastasis, and metastases in a preexisting primary thyroid tumor are exceedingly rare. We report the first case of a patient with colon cancer who was diagnosed with a thyroid metastasis in a noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP). A 55-year-old male patient presented with a 19 mm thyroid nodule in the inferior left lobe. It was EU-TIRADS 5 on echography and suspicious of papillary thyroid carcinoma (Bethesda V) on cytology. Macroscopically, the nodule was fleshy and completely encapsulated. At frozen section examination, it demonstrated follicular architecture with mild atypia. Inside the nodule was a focus of tumor with glandular architecture, marked cellular atypia, and necrosis. These findings suggested a secondary malignancy. The patient's medical history was significant for metastatic colon cancer. The definitive histology showed features of metastatic colorectal adenocarcinoma within a NIFTP. Immunohistochemical studies were confirmatory with expression of CDX2 and CK20 localized to the metastatic focus. PAX8, TG, and TTF were negative in the metastasis but expressed in the surrounding NIFTP lesion. The possibility of a metastasis to the thyroid may be considered in patients presenting with a solitary thyroid nodule with a previous history of cancer. Metastatic colorectal adenocarcinoma occurring in a NIFTP has never been reported before now, although metastases to the thyroid are documented in the literature. In cases of a secondary malignancy to the thyroid, treatment is controversial.

Background  We aimed to investigate the outcomes of the immediate surgical repair of bile duct injuries (BDIs) following laparoscopic cholecystectomy. Materials and Methods  Between January 2012 and May 2017, patients, who underwent immediate surgical repair (within 72 hours) for postcholecystectomy BDI, by the same surgical team expert in hepatobiliary surgery, were enrolled into the study. Data collection included demographics, type of BDI according to the Strasberg classification, time to diagnosis, surgical procedures, and outcome. Results  There were 13 patients with a mean age of 43 ± 12 years. Classification of BDIs were as follows: type E in six patients (46%), type D in three patients (23%), type C in two (15%), and types B and A in one patient each (7.6%). Mean time to diagnosis was 22 ± 15 hours. Surgical procedures included Roux-en-Y hepaticojejunostomy for all six patients with type-E injury, primary repair of common bile duct for three patients with type-D injury, and primary suturing of the fistula orifice was performed in two cases with type-C injury. Other two patients with type-B and -A injury underwent removal of clips which were placed on common bile duct during index operation and replacing of clips on cystic duct where stump bile leakage was observed probably due to dislodging of clips, respectively. Mean hospital stay was 6.6 ± 3 days. Morbidity with a rate of 30% ( n  = 4) was observed during a median follow-up period of 35 months (range: 6-56 months). Mortality was nil. Conclusion  Immediate surgical repair of postcholecystectomy BDIs in selected patients leads to promising outcome.

Background: Technological developments support using ultrasonography (US) in all patients, if available, and advanced diagnostic methods such as abdominal computed tomography (CT) in case of clinical suspicion during diagnostic process of acute appendicitis. We aimed to investigate whether CT was appropriately and efficiently used in the diagnosis of acute appendicitis., Methods: Between May 2013 and February 2016, 811 patients who underwent appendectomy were retrospectively reviewed from an IRB-approved database, and those who underwent a preoperative CT were enrolled into the study. Results of Alvarado scores and US were recorded in addition to which clinic requested the CT (general surgery or emergency department)., Results: The frequency of CT use in the diagnostic process was 25% (n=208/811). Ultrasound was negative for appendicitis in 53% of these patients. The mean Alvarado score was 5±1.5 (range: 3-8). General surgeons requested 57% of CTs. Alvarado scores were significantly higher in patients whose CT was requested by general surgery than in those whose CT was requested by the emergency clinic (5.6 vs. 4.7, p=0.013). Regarding histopathological results, age and Alvarado scores were significantly lower (p=0.015 and 0.037, respectively), whereas the frequency of negative CT was significantly higher (p=0.042) in those with negative appendectomy (n=29, 14%)., Conclusion: Most patients who underwent CT in the diagnostic process had an Alvarado score between 5 and 8 and negative ultrasound for appendicitis preoperatively. These findings may provide efficient use of CT in the diagnosis of appendicitis with an acceptable rate of 25% compared with the findings in current literature. However, further research is needed to ensure more efficient use of CT because negative appendectomy has been a concern in our series despite promising results of this study.

Objectives: In the pancreatic lesion cases, surgery is often planned based only on imaging results and without a preoperative histological diagnosis, due to the high risk of malignancy in combination with the difficulty of invasive interventions and limited cytopathological evaluation. In this study, the records of 20 patients who had undergone a pancreatectomy procedure and who were diagnosed with nonneoplastic pancreatic lesions were retrospectively evaluated according to the clinical and histopathological findings., Methods: A total of 122 cases of patients who underwent a pancreatectomy with suspicious lesions between 2004 and 2016 were retrospectively assessed in detail using the clinical and histopathological findings., Results: Nonneoplastic lesions were observed in 20 (16%) of 122 patients who underwent a pancreatectomy. Histopathological examination revealed 11 cases of chronic pancreatitis, 1 hematoma, 1 instance of hemorrhagic necrosis secondary to trauma, 1 pseudocyst, 1 granulation tissue, 1 retention cyst, 1 bile duct cyst, 1 patient with Castleman disease, and 1 instance of fat necrosis were seen. In 1 patient, no evidence of disease was found. In addition, among the patients with chronic pancreatitis, autoimmune pancreatitis was observed in 1, adenomyoma of the ampulla of Vater was present in 1, and a pseudocyst was found in 1 patient., Conclusion: A clinical and histopathological analysis of nonneoplastic lesions found in pancreatectomy patients was performed., Competing Interests: Conflict of Interest: None declared., (Copyright: © 2018 by The Medical Bulletin of Sisli Etfal Hospital.)

Objective: The best therapeutic approach for endoscopic retrograde cholangiopancreatography-related perforations remains controversial; while some authors suggest routine conservative management, others advocate mandatory surgical exploration. We aimed to evaluate our clinical experience of perforations during endoscopic sphincterotomy., Material and Methods: A retrospective chart review from January 2010 to October 2015 identified 20 patients with endoscopic retrograde cholangiopancreatography-related perforations. Data collection included demographics, time to diagnosis, type of perforation, treatment strategy, surgical procedure, complications, hospital stay, and outcome. All patients were classified into two groups on the basis of radiological and operative findings., Results: Only five patients underwent surgical treatment, whereas 15 patients were managed conservatively. The mean time to diagnosis was 7.8 hrs (range: 1 to 36 hrs). In patients who underwent surgical treatment, the types of perforations included type I and III in one patient each and type II in three patients. Surgical procedures included laparoscopic and open cholecystectomy with t-tube drainage in two patients each and primary repair of duodenal injury with hepaticojejunostomy in one patient. Among conservatively managed patients, eight, four, and three had type II, type III, and type IV injuries, respectively. Of these 15 patients, 60% (n=9) underwent percutaneous procedures. The mean length of hospital stay was similar for conservatively and surgically treated patients (12 vs. 12.4 days, respectively, p=0.790). One patient (5%) with type I injury died of multiorgan deficiency., Conclusion: With close close clinical follow-up, medical treatment can be beneficial for most patients, and surgical procedures should be reserved for patients with type I (definite) and type II/III injuries; in patients with these clinical parameters, conservative management will likely be unsuccessful., Competing Interests: Conflict of Interest: No conflict of interest was declared by the authors.

Multiple endocrine neoplasia (MEN1) is a rare autosomal dominant disorder characterized by primary hyperparathyroidism, enteropancreatic neuroendocrine tumors, and anterior pituitary adenomas. A 16-year-old male presented to the emergency outpatient clinic with tonic convulsions. Physical examination in the postconvulsive period was unremarkable and revealed a muscular, postpubertal adolescent. Biochemical tests at admission were consistent with hyperinsulinemic hypoglycemia and remarkable for elevated levels of liver transaminases and creatine kinase. Work-up for a potential inborn error of metabolism and Doppler ultrasound for congenital portal-hepatic shunt were negative. When the patient was questioned, he reported using the anabolic steroid stanozolol to strengthen his muscles. His enzyme levels normalized after cessation of stanozolol. Hypoglycemia did not recur on diazoxide therapy. Magnetic resonance imaging showed two discrete lesions in the pancreas. Distal pancreatectomy revealed two masses 1.1 and 1.4 cm in diameter: a solid pseudopapillary tumor and an insulinoma. The patient also had asymptomatic primary hyperparathyroidism. DNA sequence analysis of the MEN1 gene in the index patient and his father and brother revealed a previously reported "pW183S" heterozygous mutation. This case further adds to the "pancreatic tumor" phenotype of MEN1 with the presence of a solid pseudopapillary tumor. This case report also confirms the need to meticulously question drug abuse in adolescents presenting to clinics with diagnostic challenges.

An intrahepatic foreign body (FB) is rarely observed. In most cases, object passes from the gastrointestinal tract to the liver via migration. Uncomplicated intrahepatic FB can be followed without surgical intervention; however, complicated intrahepatic FB requires laparoscopy or laparotomy. Presently described is laparoscopic operation on 22-year-old female patient who had incidental sewing needle in the right liver lobe. As there were initially no complications, follow-up monitoring was recommended. However, the patient subsequently complained of stomach pain and developed fever. Laparoscopic exploration located sewing needle in the right liver lobe lateral to the gall bladder with end of needle protruding from the liver. Needle was removed with laparoscopic grasper. Review of the literature regarding 23 other intrahepatic sewing needle cases is also presented.

Background: Recently, total laparoscopic pancreatectomy has been performed at many centres as an alternative to open surgery. In this study, we aimed to present the difficulties that we have encountered in converting from classic open pancreaticoduodenectomy to total laparoscopic pancreatectomy., Materials and Methods: Between December 2012 and January 2014, we had 100 open pancreaticoduodenectomies. Subsequently, we tried to perform total laparoscopic pancreaticoduodenectomy (TLPD) in 22 patients. In 17 of these 22 patients, we carried out the total laparoscopic procedure. We analysed the difficulties that we encountered converting to TLPD in three parts: Preoperative, operative and postoperative. Preoperative difficulties involved patient selection, preparation of operative instruments, and planning the operation. Operative difficulties involved the position of the trocars, dissection, and reconstruction problems. The postoperative difficulty involved follow-up of the patient., Results: According to our experiences, the most important problem is the proper selection of patients. Contrary to our previous thoughts, older patients who were in better condition were comparatively more appropriate candidates than younger patients. This is because the younger patients have generally soft pancreatic texture, which complicates the reconstruction. The main operative problems are trocar positions and maintaining the appropriate position of the camera, which requires continuous changes in its angles during the operation. However, postoperative follow-up is not very different from the classic procedure., Conclusion: TLPD is a suitable procedure under appropriate conditions.

Background: Cystic Echinococcosis is a chronic parasitic infection, which is still an important problem in rural areas. Due to the development in technology, laparoscopic surgery has been introduced for the surgical treatment of hydatid disease of the liver (HD-L). The present study aimed to evaluate the clinical outcomes of laparoscopic versus open surgery for HD-L in a comparative analysis., Methods: Between January 2010 and March 2014, medical records of 83 patients who underwent surgery for HD-L were retrospectively analyzed. Patients' demographic data, cystic features, operative details and postoperative outcomes were reviewed from the database. All patients were divided in two groups regarding the surgical approach; Group A (open surgery, n= 69) and Group B (laparoscopic surgery, n= 14) RESULTS: Both groups were similar regarding demographic variables and cystic features. In group B, mean operative time was significantly lower when compared to Group A (89±28 minutes vs. 144±19 minutes, respectively p<0,01). Hospital stay was also lower in laparoscopic group (3.38±0.7 vs 8.81±5.4 p<0,01). Overall postoperative complication was 19% and it was similar between groups. incidence of biliary fistula was 15% (n=13)., Conclusion: Laparoscopic approach in the treatment of HD-L is safe and feasible. Additionally, it has some advantages including shorter operative time and hospital length of stay., Key Words: Conventional surgery, Hydatid disease of the liver, Laparoscopic approach, Surgical treatment.

Background: Acute cholecystitis is the most common complication of gallbladder stones. Today, Tokyo guidelines criteria are recommended for diagnosis, grading, and management of acute cholecystitis., Objectives: We aimed to evaluate the levels of C-reactive protein (CRP) at different cut-off values to predict the severity of the disease and its possible role in grading the disease with regard to the guideline., Patients and Methods: This is a retrospective study, analyzing 682 cases out of consecutive 892 patients with acute cholecystitis admitted to two different general surgery clinics in Istanbul, Turkey. Records of patients diagnosed with acute cholecystitis were screened retrospectively from the hospital computer database between January 2011 and July 2014. A total of 210 patients with concomitant diseases causing high CRP levels were excluded from the study. The criteria of Tokyo guidelines were used in grading the severity of acute cholecystitis, and patients were divided into 3 groups. CRP values at the time of admission were analyzed and compared among the groups., Results: Mean CRP levels of groups were found to be significantly different, 18.96 mg/L in Group I, 133.51 mg/L in Group II, and 237.23 mg/L in Group III (P < 0.001). Having examined CRP values among the groups, they were found to be highly and significantly correlated with the disease grade (P < 0.0001). After evaluating CRP levels according to the grade of the disease, group 2 was distinguished from group 1 with a cut-off CRP level of 70.65 mg/L, and from group 3 with a value of 198.95 mg/L. Those results were found to be statistically significant (P < 0.001)., Conclusions: CRP, a well-known acute phase reactant that increases rapidly in various inflammatory processes, can be accepted as a strong predictor in classifying different grades of the disease, and treatment can be reliably planned according to this classification.

Background/aims: The purpose of our study is researching into impact of glucagon like peptide 1 (GLP 1) analogue on liver regeneration after major hepatectomy., Methodology: 24 wistar albino rats were consecutively divided into 3 groups. Group 1: Control (sham) group day 14 (n = 8), Group 2: Liver resection group day 14 (n = 8); 70% Liver resection was performed, Group 3: Study group day 14 (n = 8); Subsequent to performing 70% liver resection, GLP-1 analogue was administered 2 times a day. (10 μgr/70 kg x 2 times). After 14 day, rats were sacrificed. Oxi- dative stress and antioxidant enzymes and mitochon- drial permeability transition, cytochrome-c, Bax, Bcl- 2, caspase-3, caspase-8 and caspase-3 activity were examined., Results: 70% Liver resection induced oxi- dative stress of liver tissue was ameliorated by GLP-1 induction. Administration of GLP increased Bcl-2 ex- pression. Decreased expression of cytochrome-c was accompanied by a decrease caspase-3, caspase-8, and Bax expression and caspase-3 activity., Conclusions: Glp 1 induction plays a regenerative role in the major hepatectomy. This effect is dependent on modulation of the antiapoptotic and antioxidative pathways by GLP 1 expression.

Primary carcinomas of the small intestine are extremely rare neoplasms. Most of these are adenocarcinomas. Primary squamous cell carcinoma (SCC) of small intestine is exceptionally rare with only occasional case reports in the literature. We report here a surgically treated patient with squamous cell carcinoma arising from duodenal diverticula in the third part of the duodenum.

Duplication of the gallbladder is a rare congenital anomaly of the gallbladder, with an estimated prevalence of 1-3 per 3800 individuals. Unless properly diagnosed preoperatively, it can lead to biliary tract injuries and postoperative complications which may require reoperative surgeries. While previously reported cases have been treated with conventional laparoscopic cholecystectomy (LC), treatment with single incision laparoscopic surgery (SILS) has not been reported yet. We herein present the case of a 58-year-old female with gallbladder duplication who was successfully treated with SILS cholecystectomy.

The gold standard of surgical treatment of colorectal anastomotic leak is abdominal drainage of collected fluid and stoma formation. Conventional laparotomy has been the preferred approach for treatment. However, both laparoscopic surgical techniquesand endoscopic stenting have gained popularity over the past years as minimal invasive approaches, especially in the management and treatment of perforations of the gastrointestinal system. We present here a successful treatment with a minimal invasive management of anastomosis leak in the early postoperative period after colon resection in a 62-year-old female patient who had undergone urgent laparoscopic intra-abdominal lavage and drainage followed by endoscopic stenting.

Malignant hypercalcemia and thrombocytopenia may result from bone metastasis of cholangiocarcinoma (CC). Our case was 53-year-old man admitted to emergency department with symptoms of anorexia, weight loss, nausea, vomiting, and general fatigue in February 2012. His laboratory findings showed hypercalcemia and thrombocytopenia. CT showed a large multinodular mass in the right lobe and, extending through left lobe of the liver. We considered the diagnosis of hypercalcemia of malignancy with elevated calcium levels and suppressed PTH level with the existence of skeletal bone metastasis and the absence of parathyroid gland pathology. Treatment of hypercalcemia with IV saline, furosemide, and calcitonin improved the patient symptoms. After the 8th day of admission, calcium level, thrombocytopenia, and other symptoms were normalized. Patient was sustained surgically inoperable and transferred to medical oncology department for the purpose of palliative chemotherapy and intended radiotherapy for bone metastasis. Hypercalcemia relapsed 4 weeks after discharge and patient died at the 5th month after admission due to disseminated metastasis. We should be aware of CC with symptomatic hypercalcemia and rarely low platelet count. The correction of hypercalcemia provides symptomatic relief and stability of patients.
