Utility of Somatostatin Receptors in Gastrointestinal Tract and Pancreas Neuroendocrine Tumors

Aim: Neuroendocrine tumors (NETs) are heterogenous group of tumors. Most of gastroenteropancreatic NETs (GEPNETs) are welldifferentiated low-grade tumors but a subset of them displays aggressive behavior. Somatostatin receptors (SSTR) play an im-portant role in the pathogenesis of GEPNETs, and they display targets for therapy. We aimed to evaluate SSTR2, SSTR3, SSTR5 by immunohistochemistry in GEPNETs and correlate with clinicopathological findings.Materials and Methods: Totally 61 cases were enrolled into this study and evaluated for SSTR2, 3, and 5 by im-munohistochemically.Results: Mostly the patients had low-grade neoplasms and 23% of them had metastatic disease. Total-ly, 73%, 47%, and 26% positivity were found by SSTR2, SSTR3, and SSTR5, respectively. The histopathological grade was increased relative to decreasing expression levels of SSTRs. Among metastatic neoplasms, SSTR2 positivity was found to be greater than a non-metastatic disease.Conclusion:In conclusion, SSTRs are useful to predict the clinical outcomes as well as target of therapy

Unusual Presentation of Meckel’s Diverticulum: Gangrene due to Axial Torsion

Meckel’s diverticulum is the most common congenital anomaly of the small bowel. The majority of cases are asymptomatic; however, life-threatening complications can also take place. We present a case of a 37-year-old male who was admitted with symptoms of acute, severe abdominal pain in the right iliac fossa. The patient was operated on with the preoperative diagnosis of acute appendicitis but the operative findings were consistent with torted Meckel’s diverticulum due to presence of mesodiverticular band and he was treated successfully with surgical resection

Multagenicity of five food additives in Ames/Salmonella/microsome test

WOS: 000238797900008The mutagenic activity of five food additives (K2S2O5 : potassium metabisulphite, KMB; K2SO4: potassium sulphate, KS; Na2SO3: sodium sulphite, SS; KNO3: potassium nitrate, KN; NaNO3: sodium nitrate, SN) were investigated using histidin auxotrophs TA98 and TA100 strains of Salmonella typhimurium in the presence or absence of S9 mix. The test substances were investigated for their mutagenic effects at non toxic concentrations of 0.83, 1.66, 3.33 and 5.00 mg/plate with and without S9 mix. All the test substances were not mutagenic on TA98 and TA100 strains of Salmonella typhimurium in the presence or absence of S9 mix except KS and SN. KS and SN showed a weak mutagenic effect on TA100 strain in the absence of S9 mix

Comparison of open and laparascopic splenectomy in elective cases

WOS: 000458742100026Purpose: The aim of this study was to compare open splenectomy (OS) and laparoscopic splenectomy (LS) in patients undergoing elective splenectomy. Materials and Methods: The study included 95 patients who underwent elective splenectomy between January 1, 2013 and January 1, 2018 in the Department of General Surgery, Faculty of Medicine, cukurova University. Demographic information, etiology, duration of operation, amount of blood loss and preoperative spleen size were measured. The necessity to switch from laparoscopic surgery to open surgery, duration of hospitalization, postoperative blood products replacement and postoperative complications were examined. Results: A total of 95 patients, 79% (n=75) who underwent OS, and 21% (n=20) who underwent LS were included in our study. The mean age in the study group was 43.0 +/- 17 (18-78) for OS and 39.3 +/- 13.9 in LS (1962). Of the patients who underwent OS, 31 were male (41.3%) and 44 were female (58.7%). Of the patients who underwent LS, 7 were male and 13 were female (65%). Of the 75 cases who underwent OS; 19 (25.3%) were treated for splenomegaly, 16 (21.3%) for immune thrombocytopenic purpura (ITP), 11 (14.7%) for a mass, and 7 (9.3%) cases were operated on for Thalassemia. Of the 20 cases who underwent LS; 12 (60%) cases were operated on for ITP, 3 (15%) cases for hemolytic anemia and 2 (10%) cases for lymphoma.The length of hospital stay, amount of bleeding and spleen size were superior in LS; while the duration of surgery was significantly higher in OS. Conclusion: LS is a stronger alternative to OS because of its lower complication rate, hospitalization time and cost

Abdominal extragenital endometriosis: single centre experience

WOS: 000437950900019Purpose: This study aimed to present our clinical experience on symptomatic intaabdominal extragenital endometriosis cases. Materials and Methods: In this study, patients undergoing surgery various indications and for which final histopathologic results reported as endometriosis were evaluated. Demographic characteristics, clinical presentations, localization of disease, surgical procedures and recurrence rates within follow-up period were presented. Results: Histopathologically confirmed 778 endometriosis patients were retrospectively analyzed. Extragenital abdominal endometriosis were present in 32 (4.1%) patients and all cases were symptomatic. The most common symptoms at index admission were mass detected within abdominal wall (n: 13; 40.6%) and chronic recurrence abdominal/pelvic pain (n: 9, 28.1%). 22% (n=7) of patients with abdominal extragenital endometriosis were diagnosed preoperatively. The operations performed were as follows: mass excision from the abdominal wall (n=14, 43.8%), appendectomy (n=5, 15.7%), pelvic mass excision(n=6, 18.8%), anterior resection (n=3, 9.4%), right hemicolectomy (n=2, 6,3%), and laparotomy with urinary stenting (n=2, 6,3%). Recurrence is reported in 6 (18.7%) cases at median follow-up of 42 months. Conclusion: Due to extragenital involvement, endometriosis should be part of differential diagnosis in all women who are reserved for abdominal surgery during reproductive era. Along with the complete excision, wound protector use can potentially decrease recurrence rates in cases diagnosed pre- or intraoperatively as endometriosis

Long-term Outcomes of Surgical Management of Insulinoma: Single Center Experience

Objective: Limited data are available in regards to the surgical management and outcomes of insulinoma. This study aimed to assess the outcomes associated with surgical treatment of insulinoma, as the most common pancreatic endocrine tumor. Methods: Medical records of patients who diagnosed as insulinoma from 2000 to 2010 at General Surgery Department of Cukurova University Hospital were retrospectively reviewed. Surgical treatment (resection vs. enucleation) was based on preoperative radiological investigations (abdominal spiral contrast tomography, ultrasound, selective angiography for selected cases) and intra-operative ultrasound imaging once indicated. Results: Surgically treated thirteen patients (F/M:9/4) who diagnosed with insulinoma were assessed with a mean follow-up of 5.3 (0.5-10) years. Enucleation and distal pancreatectomywere performed for 11 and 2 (one of those is spleen-preserving) patients, respectively. No mortality was recorded. All patients became normoglycemic after surgery without re-operation and with acceptable complication rates (n=3 pancreatic fistula, n=1 pancreatitis). Conclusion: Surgical treatment of insulinoma is associated with favorable outcomes.Intra-operative ultrasound with manual palpation is still the gold standard for localizing insulinoma. Location, size and relationship with main pancreatic duct of the lesions are key components for the selection of optimal surgical procedure

Sekonder peritonitte prokalsitonin, CRP ve tiroit hormonlarının prognostik değeri; ileriye yönelik çalışma

AMAÇ: Enfeksiyon ve sepsis, sekonder peritonitli hastalarda morbidite ve mortalitenin en önemli sebeplerinden biri olmaya devam etmektedir. Klinisyenler helen septik komplikasyonların erken ve güvenilir tanı yöntemini bulma konusunda çaba sarfetmektedir. Bu çalışmada sekonder peritonitin şiddetini belirlemede enflamatuvar markır olarak Prokalsitonin (PKT), C-reaktif protein (CRP) ve tiroit hormonlarının yerini değerlendirmeyi amaçladık. GEREÇ VE YÖNTEM: Ocak 2008-Ocak 2010 tarihleri arasında, sekonder peritonit nedeniyle ameliyat olan 84 ardışık hasta üzerinde ameliyat öncesi ve sonrası 1-3-5-7-14. günlerde PKT, CRP ve tiroit hormaon seviyeleri incelendi. Veriler Statistical Package for Social Sciences 15.0 (SPSS 15.0) programında analiz edildi. BULGULAR: Organ perforasyonu (peptik ülserperforasyonu, ince bağırsak ve kolon perforasyonu) olan olgular değerlendirildiğinde, PKT anlamlı olarak düşük seyretti. Ameliyat sonrası komplikasyonu olan veya ölen hastalara göre ameliyat sonrası dönemi sorunsuz olan veya taburcu olan hastalarada yüksek tiroit hormon düzeyler gözlendi. PKT düzeyleri ise CRP düzeylerleri ve beyaz küre sayısıyla anlamalı olarak ilişkili bulundu. TARTIŞMA: Ameliyat sonrası komplikasyonların yokluğunda PKT, sekonder peritonit tanısında CRP'den daha iyi bir belirliyicidir. Çalışmamız sekonder peritonitin şiddetini belirlemede düşük tiroit hormon düzeylerinin önemli bir prognostik faktör olduğunu ortaya koymuştur.AMAÇ: Enfeksiyon ve sepsis, sekonder peritonitli hastalarda morbidite ve mortalitenin en önemli sebeplerinden biri olmaya devam etmektedir.
