Objective: Spontaneous intestinal intramural hematoma is a rare complication of anticoagulant treatment. In this study, we retrospectively evaluated 14 patients with the diagnosis of intramural hematoma of the small intestine who were followed-up and treated in our clinic, and we aimed to determine current approaches in the diagnosis and treatment of intramural hematoma. Material and Methods:Between February 2010-October 2012, 14 patients diagnosed with small intestinal intramural hematoma were retrospectively analyzed. Nine patients were followed due to clinical findings and 5 patients underwent operation with a histopathological diagnosis of intramural hematoma. Results:Abdominal computed tomography demonstrated ileal and jejunal wall thickening in 10 patients, while findings were consistent with mesenteric vascular disease in four. Five patients were operated due to mechanical bowel obstruction and acute abdomen. The other 9 patients were followed up with medical treatment and 8 of these patients were already using warfarin due to cardiac bypass and valve replacement. Conclusion:Spontaneous intestinal intramural hematoma is a rare cause of small bowel obstruction due to intramural hematoma, which is encountered even more rarely. An intramural hematoma should be considered among differential diagnosis of patients who present with abdominal pain and symptoms of obstruction with a history of anticoagulant drug use and elevated International Normalized Ratio (INR) levels. Early diagnosis and medical follow-up can provide a good response to treatment in the majority of patients without requiring surgery.

The most convenient surgical procedure for benign thyroid diseases is still controversial. The aim of this study is to determine the recurrence rate and risk factors for recurrence after different thyroidectomy procedures in multinodular goiter patients. Patients were separated into two groups according to the detection of a recurrent nodule or not after thyroidectomy. Of the 748 patients, 216 (29%) had recurrence, while 532 had no recurrent nodule. The difference between surgical procedures described as subtotal (ST), near total (NT) and total thyroidectomy (TT) was statistically significant. Transient hypoparathyroidism was significantly higher in NT and TT, when compared to ST patients (P < 0.05). Young age, bilateral multinodular goiter and insufficient surgery are risk factors affecting recurrence for benign nodular thyroid disease. Currently, subtotal procedures should be discontinued and total or near total procedures should be preferred. Meanwhile, the probability of a higher risk of hypoparathyroidism should be kept in mind.

Regarding the complications of peptic ulcer, a perforation remains the most important fatal complication. The aim of our retrospective study was to determine relations between postoperative morbidity and comorbid disease or perioperative risk factors in perforated peptic ulcer. In total, 239 patients who underwent emergency surgery for perforated peptic ulcer in Ege University General Surgery Department, between June 1999 and May 2013 were included in this study. The clinical data concerning the patient characteristics, operative methods, and complications were collected retrospectively. One hundred seventy-five of the 239 patients were male (73.2%) and 64 were female (26.8%). Mean American Society of Anesthesiologists (ASA) score was 1 in the patients without morbidity, but mean ASA score was 3 in the morbidity and mortality groups. Primary suture and omentoplasty was the selected procedure in 228 of the patients. Eleven patients underwent resection. In total, 105 patients (43.9%) had comorbidities. Thirtyseven patients (67.3%) in the morbidity group had comorbid diseases. Thirteen (92.9%) patients in the mortality group had comorbid diseases. Perforation as a complication of peptic ulcer disease still remains among the frequent indications of urgent abdominal surgery. Among the analyzed parameters, age, ASA score, and having comorbid disease were found to have an effect on both mortality and morbidity. The controversial subject in the present study is regarding the duration of symptoms. The duration of symptoms had no effect on mortality nor morbidity in our study.

Treatment options of pilonidal sinus, which has high recurrence rates, is still controversial. In this study, we aimed to analyze for possible factors affecting recurrence. Forty-one patients with recurrent pilonidal sinus were included in this study. Of them, 33 were male and 9 were female (mean age, 24.9 years; age range, 16-42). Factors (i.e., risk factors) were detected in 32 patients. Excision-secondary healing and lay open was performed on 30 of the patients admitted with recurrence. Excision and flap closure was applied on 11 patients. Our recurrence rate was 9.7%. The recurrence rate of our study is compatible with the literature. Comparative studies are needed to determine the appropriate method to decrease recurrence rate.
