Background: As a chronic condition, pilonidal disease affects a young population, and recovery after the surgical procedures performed to treat this condition require time off from work. Therefore, the search for an ideal treatment is still ongoing.

Objective: The aim of this study was to compare early and late results of 2 minimally invasive treatment options used to treat pilonidal disease.

Article Synopsis
  • The study compares the effectiveness of the modified Alvarado score and the RIPASA scoring system in diagnosing acute appendicitis (AA) among 100 surgical cases.
  • The RIPASA score showed higher sensitivity (94%) and specificity (88%) compared to the modified Alvarado score, which had a sensitivity of 88% and specificity of 69%.
  • Overall, the RIPASA scoring system was concluded to be more accurate for predicting AA, demonstrating better performance in diagnosing this condition.

Objectives: The aim of this study was to compare minimally invasive preperitoneal (MIP) single layer mesh repair with total extraperitoneal (TEP) inguinal hernia repair in terms of complications, recurrence, and chronic pain.

Material And Methods: A total of 240 patients who underwent elective, primary, unilateral inguinal hernia operation between April 2011 and September 2012 were divided into two randomized groups. The first group underwent MIP repair and the second group underwent TEP repair.

Background: Endoscopic retrograde cholangiopancreatography (ERCP) is widely used for treatment of biliary disorders. There are several studies to increase the success rate and decrease the complication rate of ERCP. In this study we aimed to evaluate the affect of safety steps in success and complication rate of ERCP.

Primary hyperparathyroidism (PHPT) has been considered a cause of insulin resistance (IR) and impaired glucose metabolism. However, there are conflicting results related with the recovery of insulin resistance in patients with PHPT following curative parathyroidectomy. Our aim is to evaluate the effects of curative parathyroidectomy on IR in patients with PHPT.

Background: Acute appendicitis (AA) is the most common reason for abdominal surgery in the world. The aim of this study was to evaluate the effect of medical treatment on histological findings in rabbits with AA.

Methods: Twenty-one male New Zealand rabbits were divided into 3 groups: appendix ligation and medical treatment, appendix ligation and no treatment, and control group, which underwent only laparotomy.

Objective: Hydatid cyst disease (HCD) is a zoonotic infestation of Echinococcus granulosus, which is frequently seen in some regions of the world. Unusual localization of Echinococcus granulosus is very rare. Hence, we would like to present our experience of identifying an extra-hepatopulmonary location of hydatid cysts.

Objective: Surgery and percutaneous aspiration-injection-re-aspiration (PAIR) are widely accepted treatment modalities for hepatic hydatid cysts. Endoscopic retrograde cholangiopancreaticography (ERCP) acts as a minimally invasive rescue method for the biliary complications of both the hydatid cysts and treatment modalities. The aim of this study was to identify the role of different treatment modalities in the obliteration of hydatid cysts.

Background: Pilonidal sinus is a chronic inflammatory disorder of the intergluteal sulcus. The disorder often negatively affects patients' quality of life, and there are numerous possible methods of operative treatment for pilonidal sinus. The aim of our study was to compare the results of 3 different operative procedures (tension-free primary closure, Limberg flap, and Karydakis technique) used in the treatment of pilonidal disease.

Purpose: To clarify the role of medical treatment in the management of acute appendicitis and the value of C-reactive protein (CRP) for predicting its failure.

Materials And Methods: Patients with clinically diagnosed acute appendicitis, confirmed by imaging studies, were enrolled in this study. We measured leukocyte counts and CRP levels and recorded success and recurrence rates and the efficiency of medical treatment during follow-up.

Background: Endoscopic retrograde cholangiopancreatography (ERCP) is commonly used in both the diagnosis and the treatment of biliary and pancreatic disorders. The aim of this study is to evaluate the effects of OB usage during ERCP on duodenal motility, the tolerability of the procedure (by patients) and the difficulty of the procedure (by the endoscopist).

Method: The study was conducted in Konya Training and Research Hospital General Surgery Endoscopy Unit in randomized prospective pattern.

Background: This study was designed in order to compare the effectiveness of subtotal-total colectomy with other surgical methods in the treatment of malignant obstructive lesions of the left colon.

Methods: Patients admitting with symptoms of colonic obstruction and treated by emergency surgery in Konya Education and Research Hospital between 2004 and 2007 were enrolled. Patients were divided into three groups according to the surgical procedures (Group I: Hartmann procedure; Group II: resection + diverting ileostomy; Group III: total-subtotal colectomy).

Although tension-free techniques of hernia repair using synthetic meshes have yielded encouraging results, the best method of inguinal hernia repair is still unclear. The aim of this study was to compare the responses of inflammatory mediators and postoperative pain relief following laparoscopic total extraperitoneal (TEP) hernioplasty, open tension-free mesh hernioplasty (Lichtenstein), posterior preperitoneal mesh hernioplasty (Nyhus procedure), and Bassini procedure. Patients with primary inguinal hernia were randomized in the operating room to undergo one of these repair techniques.
