Outcome and Factors Related to Isolated Liver Metastasis due to Breast Cancer.

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.

Evaluation of immunohistochemical expression of novel neuroendocrine marker INSM1 and histological tumor growth pattern in well-differentiated neuroendocrine tumors of the appendix: 15-year single tertiary center experience.

Introduction: Well-differentiated neuroendocrine tumors of the appendix (A-WDNET) are the most common neoplasms of the appendix but are rare and incidental. INSM1 is a novel transcription factor marker with high sensitivity and specificity for neuroendocrine differentiation. It may display architecturally diverse tumor growth patterns including solid, nest, insular trabecular, and acinar.

What should be done in patients diagnosed with xanthogranulomatous cholecystitis? Case-control study.

Objective: In this study, we aimed to compare development of complications, malignancy and confusion rates in the preliminary diagnosis in patients with xanthogranulomatous cholecystitis identified.

Methods: In this study, 2803 patients undergone cholecystectomy between January 2010 and December 2016 were retrospectively evaluated. Patients with xanthogranulomatous cholecystitis identified in the histopathological examination were classified as Group 1 and patients with cholelithiasis, cholecystitis, and malignancy detected were classified as Group 2.

Evaluation of the gastrointestinal stromal tumors for clinical features, histopathological findings and prognostic criteria: A case-control study.

Objective: In this study, we reviewed GISTs with all morphological and immunohistochemical findings and assessed the prognostic parameters of these tumors.

Methods: Files of 40 cases with GIST operated between 2002 and 2008 were retrospectively examined in this study. Patients were grouped as patients with and without recurrence within postop 1 year.

Non-operative management of civilian abdominal gunshot wounds.

Background: In this study, we aimed to evaluate the results of selective non-operative management in patients with civilian abdominal gunshot wounds.

Methods: Patients hospitalized and monitored in our clinic due to civilian abdominal gunshot wounds between January 2009 and January 2018 were retrospectively examined. Patients were studied concerning age, gender, mechanism of injury, anatomic injury site, Penetrating Abdominal Trauma Index (PATI), Injury Severity Score (ISS), Revised Trauma Score (RTS), treatment method, time to operation, days of hospitalization and mortality.

Primary neuroendocrine carcinoma of the breast: a 5-year experiences.

Purpose: Breast neuroendocrine carcinomas constitute approximately 0.3-0.5% of all breast cancers.

Risk factors for complications after endoscopic retrograde cholangiopancreatography A referral Center experience.

Aim: Endoscopic retrograde cholangiopancreatography (ERCP) is an important diagnostic and therapeutic tool in patients with hepato-pancreatobiliary diseases. In the present study, we sought to determine predictors of post-ERCP complications at our institution.

Methods: A retrospective analysis of patients who underwent ERCP in between January 2010 and November 2011 was done.

Misleading findings of liver-specific MR contrast agent for radiological diagnosis of cysto-biliary communication in hydatid cysts.

Objective: To investigate the effectiveness of gadoxetic acid-enhanced magnetic resonance cholangiopancreatography (CE-MRCP) and T2-weighted half-Fourier acquisition single-shot turbo spin-echo (T2W HASTE) sequences for diagnosis of cysto-biliary communication in hydatid cysts compared to surgical results.

Methods: Preoperative abdominal magnetic resonance imaging examinations of patients who underwent surgery for hepatic hydatid cysts were reviewed by two radiologists retrospectively. A total of 45 patients with hydatid cysts were included.

An incidental giant preperitoneal fibrolipoma diagnosed during laparoscopic cholecystectomy.

Preperitoneal lipomas are rare in clinical practice. Here we report an unexpected diagnosis of a giant preperitoneal fibrolipoma detected intraoperatively during laparoscopic cholecystectomy in a 56-year-old woman. The mass was excised and a histopathological examination confirmed fibrolipoma.

Sinistral Portal Hypertension Due to Pancreatic Hydatid Cyst.

Hydatid disease is caused by Echinococcus granulosus. Hydatid cysts are commonly located in the liver and lungs. The occurrence of pancreatic hydatid cysts is very rare, even in endemic areas.

Intraoperative diagnosis of cecal diverticulitis during surgery for acute appendicitis: Case series.

Objective: Cecal diverticulum is a rare entity, and can cause acute abdomen by the way of diverticulitis and perforation of diverticulitis. In this study, we aimed to perform an analysis of patients that have cecal diverticulitis, and presented with acute abdomen.

Material And Methods: Patients who were admitted to emergency clinic between 2009-2012 and had acute abdomen due to cecal diverticulitis were included into study retrospectively.

Lumbar (Petit's) hernia: A rare entity.

Lumbar hernias are rare and diagnostically challenging for surgeons. We present the case of a middle-aged patient who presented with swelling in the left back. Subcutaneous lipoma was included in the differential diagnosis.

Review of clinical experience with acute cholecystitis on the development of subsequent gallstone-related complications.

Background/aim: Recently, surgery during admission has been advocated for acute cholecystitis, rather than delayed surgery after conservative treatment. This study was designed to perform early surgeries and analyze the criteria used for conservative management followed by delayed surgery.

Materials And Methods: After implementation of a study with the aim of performing early surgery, a retrospective review using a prospective database during the period of June 2009 to June 2011 was established.

Laparoscopic excision of a retroperitoneal ganglioneuroma.

Objective: Ganglioneuromas are rare benign tumors originating from ganglion cells. Ganglioneuromas are detected incidentally because they are asymptomatic. We report a case of laparoscopic excision of a retroperitoneal ganglioneuroma.

Spontaneous remission of sclerosing mesenteritis.

Sclerosing mesenteritis is a rare fibroinflammatory disorder mostly affecting the small bowel mesentery with unknown etiology. Its clinical presentation varies according to the pathologic stages of sclerosing mesenteritis. In the early stages, nonspecific abdominal symptoms are usually seen, whereas severe small intestinal obstructive symptoms predominate in late stages.
