BACKGROUND Pilonidal sinus is a common disease in young adults that carries high postoperative morbidity and patient discomfort. Controversy still exists about the best surgical technique for the treatment of the disease in terms of recurrence rate and patient discomfort. METHODS From January 2000 to November 2003, 100 consecutive age- and sex-matched(More)
INTRODUCTION After nonoperative decompression of acute sigmoid volvulus, definitive surgery is necessary because of the high risk of recurrence. However, the optimal surgical technique for this purpose has not been determined. METHODS We studied 106 consecutive patients (mean age, 60.9 (range, 26-93) years) who underwent emergency resection for acute(More)
Spontaneous perforation of gastric cancer is a serious complication with a very high incidence of mortality. In order to evaluate the prognostic factors influencing mortality in patients with gastric tumour perforations and to clarify the optimal surgical treatment, the records of patients at one centre during a 5-year period were evaluated retrospectively.(More)
Intestinal ischemia/reperfusion provokes a local inflammatory response leading to a systemic inflammatory state. In this study we aimed to assess the effects of intestinal ischemia/reperfusion injury on anastomotic healing in the left colon with an intact vascular supply. A total of 94 Wistar albino rats were divided into three groups: sham-operated control(More)
We aimed to identify prognostic factors affecting clinical outcomes in emergent primary resection. A retrospective analysis of prospectively acquired data of 230 consecutive emergent patients between August 1994 and January 2005 were evaluated in this study. Sixty-nine patients applied with right colon obstruction and 161 patients with left. Resection and(More)
Allopurinol has been widely used to reduce the severity of the reperfusion injury. However, conflicting data have been reported regarding the dosage, the duration of the timing, and the administrative regimen of the drug. The aim of this study was, therefore, to evaluate the effects of short versus long periods of allopurinol pretreatment on the anastomotic(More)
Intraabdominal adhesions represent a significant problem because of the morbidity associated with adhesive disease, including small bowel obstruction, difficulties in reoperative surgery, and possibly chronic pain. Coating solution of sodium hyaluronate (Sepracoat; Genzyme Production-Surgical Products, Cambridge, MA) was studied in New Zealand white rabbits(More)
BACKGROUND Reduced postoperative pain after laparoscopic cholecystectomy (LC) compared to open cholecystectomy (OC) may be able to be further optimized. To reduce pain, focus should be directed on the effects of individual components of pain. METHODS A double-blind, randomized, controlled trial was carried out in a tertiary care hospital. Fifty-three(More)
Hernia repair is one of the most frequent procedures in surgery. The aim of this study is to compare the early and long-term health status and clinical outcomes of patients in the postoperative period of Stoppa and bilateral Lichtenstein hernia repair in bilateral groin hernias. The Stoppa group consisted of 22 patients, and the bilateral Lichtenstein group(More)
Background: Although it has been been shown that the elevation of abdominal pressure causes splanchnic ischemia, the pathophysiological changes that occur during laparoscopic cholecystectomy are still under investigation. Our aim was to evaluate the changes in nitric oxide (NO), malondialdehyde (MDA), and gastric intramucosal pH (pHi) during laparoscopic(More)
