A 38-year-old male presented to the emergency department with abdominal pain and bulge. He had a history of irritable bowel syndrome for 1 year with complaint of dyspepsia. Physical examination revealed a distended abdomen with a huge palpable mass located in the paraumblical region.

The value of combined elevation of D-dimer and neopterin as a predictive parameter for early stage acute mesenteric ischemia: An experimental study.

Background The diagnosis of acute mesenteric ischemia is variable. Early diagnosis is important for reducing the mortality and morbidity rates. Aim This experimental study aims to investigate the diagnostic utility of D-dimer and neopterin as a marker for the early stage of acute mesenteric ischemia caused by occlusion of superior mesenteric artery.

The Effects of Total Colectomy on Bacterial Translocation in a Model of Acute Pancreatitis.

Prevention of secondary infection is currently the main goal of treatment for acute necrotizing pancreatitis. Colon was considered as the main origin of secondary infection. Our aim was to investigate whether prophylactic total colectomy would reduce the rate of bacterial translocation and infection of pancreatic necrosis.

Efficacy of wound infiltration with lornoxicam for postoperative analgesia following thyroidectomy: a prospective, randomized, double-blind study.

Background/aim: Postoperative pain control constitutes a major problem and studies have focused on reducing opioid requirements using regional techniques. We aimed to investigate the efficacy of wound infiltration with lornoxicam on postoperative pain control following thyroidectomy.

Materials And Methods: In this prospective, randomized-controlled study, 80 patients scheduled for thyroidectomy were randomly assigned to 2 groups.

Body mass index and ghrelin levels after laparoscopic Nissen fundoplication.

Purpose: The study aims to evaluate the changes between body mass index (BMI) and ghrelin levels after laparoscopic Nissen fundoplication (LNF).

Methods: Twenty-four consecutive patients with gastroesophageal reflux disease who were scheduled for LNF consented to participate in the study. The participants' age, sex, preoperative (phase 0), postoperative 1st week (phase 1) and postoperative 4th week (phase 2) dysphagia scores, plasma ghrelin levels, and BMI were recorded.

[Analysis of the pediatric trauma score in patients wounded with shrapnel; the effect of explosives with high kinetic energy: results of the first intervention center].

Background: We aimed to assess the pediatric trauma score analysis in pediatric trauma cases due to shrapnel effect of explosives material with high kinetic energy.

Methods: The data of 17 pediatric injuries were reviewed retrospectively between February 2002 and August 2005. The information about age, gender, trauma-hospital interval, trauma mechanism, the injured organs, pediatric Glasgow coma score (PGCS), pediatric trauma score (PTS), hemodynamic parameters, blood transfusion, interventions and length of hospital stay (LHS) were investigated.

Surgical treatment of caustic esophageal strictures in adults.

Background And Aims: Caustic esophageal injury is a rare clinical condition in adult patients. Although dilatation, or the conservative approach, is the primary treatment method, some patients require surgical intervention. Because of the rarity of such cases, standard surgical treatment algorithms cannot be utilized.

Rectus abdominus fascial sheath usage for crural reinforcement during surgical management of GERD: preliminary report of a prospective randomized clinical trial.

Purpose: Many materials are currently being used to reinforce the crural repair. Perforation, intensive fibrosis, and price are limiting the usage of these materials. Our purpose was to seek an alternative, cheap, always available, and inert material to use for cruroplasty reinforcement.

The effects of amlodipine on the biochemical and histopathological changes in the rabbit ileum subjected to ischemia-reperfusion.

Objective: The aim of this study was to determine the potential, protective effects of amlodipine in an experimental, ischemia-reperfusion (I/R) model in the rabbit small intestine.

Materials And Methods: The rabbits were divided into four groups: sham-operated, amlodipine (10 mg/kg) + sham-operated, I/R, and I/R + amlodipine (10 mg/kg) groups. An intestinal I/R model was applied to the rabbits.

[The disguised face of blast injuries: shock waves].

Background: The increase in terrorist attacks has brought a profound and new knowledge of blast injuries. In order to improve our knowledge regarding the mechanisms of blast injuries, we analyzed the effects of shock waves.

Methods: 100 g TNT and 1000 g C4 were detonated and recorded by high-speed camera.

The importance of urine 5-hydroxyindoleacetic acid levels in the early diagnosis of acute appendicitis.

Purpose: Acute appendicitis is one of the most common surgical emergencies. Diagnosis is usually made depending on the presenting history, clinical evaluation, and laboratory tests. The aim of this study was to investigate the role of urinary 5-hydroxyindoleacetic acid (U-5-HIAA) in the early diagnosis of acute appendicitis.

A comparison of different hemorrhoidectomy procedures.

Objective: To evaluate the pain level, analgesic consumption, operation time, bleeding and early complications after open and closed hemorrhoidectomy using a harmonic scalpel (HS) and classical methods.

Methods: Between January 2005 and January 2006, 87 patients with grade III-IV hemorrhoids, admitted in General Surgery Clinic, Gulhane Military Medical Academy, Ankara, Turkey were enrolled in the study. They were randomized into open HS (n=22), closed HS (n=22), Miligan Morgan (n=22), and Ferguson (n=21) hemorrhoidectomy.

Late presentation of blunt right diaphragmatic rupture (hepatic hernia).

Diaphragmatic rupture occurs in 0.8% to 3.6% of patients after blunt or penetrating thoracoabdominal trauma, and the preoperative diagnosis is difficult.

Accurate positioning of the 24-hour pH monitoring catheter: agreement between manometry and pH step-up method in two patient positions.

Aim: To investigate the agreement between esophageal manometry and pH step-up method in two different patient positions.

Methods: Eighteen subjects were included in the study. First, the distance from the nose to the proximal border of the lower esophageal sphincter (LES) was measured manometrically.

[A rare cause of bleeding intestinal intussusception in adult: jejunal lipoma].

Small bowel neoplasms are usually diagnosed when patients are referred with complications such as hemorrhage or obstruction. Intestinal lipomas are the third most frequent benign tumors among all intestinal neoplasms and their definite diagnosis is usually obtained after histopathological examination of the resected specimen. A 76 year-old male patient with partial intestinal obstruction and rectal bleeding at admittance was found to have an abdominal mass on ultrasound.

Stump viscera caused by an incomplete operation can present the same symptoms as before the first operation. Furthermore, as an acute clinical event, these incomplete resections may sometimes cause acute abdomen and may need emergency surgical intervention. A 34-year-old woman with a history of laparoscopic cholecystectomy 5 days before was admitted with acute abdominal symptoms.
