Article Synopsis
  • * The study reviewed 19 patients, predominantly experiencing hypoglycemia, with tumor locations identified in 74% of cases via CT and 88% via intraoperative ultrasound, and the most common surgical procedure was enucleation (53%).
  • * The findings suggest that accurately locating insulinomas is vital for the right surgical approach, with enucleation recommended for suitable patients due to its higher success rates and lower serious morbidity, despite a higher occurrence of pancreatic fistulas.

Synchronous primary neoplasms of Meckel's diverticulum and colon malignancies are rarely reported in the literature. We present three patients with synchronous primary neoplasms of Meckel's diverticulum and colon malignancies. All tumors located in Meckel's diverticulum were incidentally found at laparotomy and the definitive diagnosis was made with microscopic examination of surgical specimens.

Background: Many imaging methods such as ultrasonography, computed tomography (CT), magnetic resonance imaging, and endoscopy are used to identify the problems or complications that occur in the perioperative period and to determine the appropriate therapeutic approach. Specialists at surgical clinics and intensive care units sometimes need diagnostic procedures that can give quick results or reveal unexpected results. In particular, rapid on-site evaluation of patients followed under intensive care conditions has several advantages.

Mirizzi syndrome (MS) is a syndrome that causes chronic destructive and fibrotic changes because of compression and inflammation in the main biliary tract. MS remains to be a serious problem due to its high morbidity. In this study, it is aimed to evaluate the diagnostic tools, risk factors and clinical output data we apply to our patients with MS in the light of the literature.

Unlabelled: This study aimed to investigate the coexistence of pilonidal sinus disease (PSD) and hirsutism in female patients.

Materials And Methods: The demographic and clinical data of 164 female patients who underwent surgery for PSD between January 2007 and May 2014 were evaluated for this retrospective cross-sectional study. Data collected for this study were age, BMI, the modified Ferriman and Gallwey scale (mFGS) for hirsutism, main symptoms, type of surgery, early postoperative complications (wound infection, wound dehiscence), recurrence, and follow-up.

Objectives: To report the case of a patient diagnosed with acute mesenteric vein thrombosis (AMVT) associated with Factor V Leiden mutation and a history of in vitro fertilization and embryo transfer and review the literature on risk factors and treatments performed for AMVT.

Materials And Methods: We reported the case of a 37-year-old pregnant woman. A bibliographic search was carried out in Medline/PubMed and LILACS, filtering by type of language (English and Spanish).

Objective: The purpose of this study is to investigate whether there was a difference between the midline skin and the healthy skin in the lateral by means of total amount of collagen and Type I/III ratio which was the indicator of the collagen structure.

Material And Methods: Fifty patients with pilonidal sinus disease were enrolled. Samples were prepared from the midline skin of the sinus where the holes were located and lateral skin of the resected material.

Background: One of the most feared complications of surgeons dealing with hepato-pancreato-biliary (HPB) surgery is hepatic artery (HA) injury. Here, we aimed to evaluate our clinical experience (laceration, transection, ligation, and resection) related to HA traumas, which have serious morbidity and mortality risks, in the light of literature data and the rapidly evolving management methods in recent years.

Methods: The files of 615 patients who were operated on for HPB pathologies in the last decade, in our hospital, were retrospectively reviewed.

Background: The omentum is an organ that is easily sacrificed during abdominal surgery. The scope of omentectomy and whether a routine omentectomy should be performed are still unknown.

Aim: To review the literature in order to determine the physiological functions of the omentum and the roles it plays in pathological events in order to reveal the necessity for removal and preservation of the omentum.

Background: The hepatic artery (HA) is one of the most threatened vascular structures during hepatopancreatobiliary (HPB) surgeries and interventional procedures. It can be affected by many clinical pictures, especially tumors, due to its anatomical position and neighborhood.

Aim: To reveal the evolution and recent developments in the management of HA traumas in the light of the literature.

Background: Hepaticojejunostomy is a challenging and complex procedure to be administered with the confidence, in conditions which contain a large number of bile duct damaged by benign pathologies or major bile duct trauma.

Methods: Here, our clinical series of portoenterostomy (PE), in which we applied in patients who had aggressive hilar dissection for hilar benign biliary pathologies and major bile duct traumas during laparoscopic cholecystectomies were discussed in the light of the literature. The PE procedure was performed in the presence of three or more bile ducts that could not be merged.

Article Synopsis
  • This study outlines a simplified two-step technique for transvaginal natural orifice transluminal endoscopic surgery (vNOTES) and provides video evidence from its application.
  • The patients involved were a 27-year-old with ovarian torsion and a 25-year-old with an ectopic pregnancy, both of whom underwent diagnostic and therapeutic procedures via vNOTES.
  • Key steps included creating a colpotomy, confirming the diagnosis using an endoscope, and performing specific surgical interventions while ensuring safety and hemostasis.

Hepaticojejunostomy is a challenging and complex procedure to be done with confidence in conditions that contain a large number of segmental bile ducts. Portoenterostomy can be defined as the joining of multiple bile ducts into a single cavity using segmenter bile duct ends, stents, and surrounding connective tissues. During surgery, in cases with advanced stage biliary tract tumors that cannot be performed hepatectomy, after aggressive dissections to provide a negative surgical margin, a large number of segmental bile ducts can be revealed and needs to ensure the continuity of bile flow.

Background: Harmonic focus (HF) was introduced in thyroid surgery in an effort to reduce operation time and complications.

Objective: The present study aimed to compare function of superior laryngeal nerve and incidence of other postoperative complications in total thyroidectomies using HF and conventional ligation (CL).

Methods: The trial is a randomized single-center, single-blinded study.

Subcutaneous localization of an hydatid cyst is quite rare, and is found in literature in the form of case presentations. Other points worthy of attention are the lack of other foci in the majority of these cases, and the negative results of serology. In this study, two primary subcutaneous hydatid cyst cases, one in the facial area (53-year old female) and the other on the back (37-year old female), have been examined with reference to literature.

Purpose: To compare the healing properties of lateral internal sphincterotomy (LIS) and isosorbide dinitrate (ISDN) ointment for chronic anal fissure.

Methods: Patients with a chronic anal fissure were randomly assigned to a group treated with ISDN ointment (n = 105) or a group treated with LIS (n = 102). The same investigators examined the patients in a blinded manner, 1, 2, 3, 6, and 12 months after the treatments.
