Gastrointestinal stromal tumors (GISTs) represent a rare group of neoplasms of the digestive tract deriving from the mesenchyme. Giant GISTs (over 10 cm in diameter) represent only 20 % of all cases and are associated with a high risk of malignancy. We present the case of a giant GIST of the jejunum successfully treated by surgical resection and adjuvant therapy with imatinib. 相似文献

Retained surgical sponges (RSS) are an avoidable complication following surgical operations. RSS can elicit either an early
exudative-type reaction or a late aseptic fibrous tissue reaction. They may remain asymptomatic for long time; when present,
symptomatology varies substantially and includes septic complications (abscess formation, peritonitis) or fibrous reaction
resulting in adhesion formation or fistulation into adjacent hollow organs or externally. Plain radiograph may be useful for
the diagnosis; however, computed tomography is the method of choice to establish correct diagnosis preoperatively. Removal
of RSS is always indicated to prevent further complications. This is usually accomplished by open surgery; rarely, endoscopic
or laparoscopic removal may be successful. Prevention is of key importance to avoid not only morbidity and even mortality
but also medicolegal consequences. Preventive measures include careful counting, use of sponges marked with a radiopaque marker,
avoidance of use of small sponges during abdominal procedures, careful examination of the abdomen by the operating surgeon
before closure, radiograph in the operating theater (either routinely or selectively), and recently, usage of barcode and
radiofrequency identification technology. 相似文献

Aim: Τo determine the prevalence of impacted teeth in an adult Greek population, according to type, sex, and age. Methods: The major source of data for this study was the orthopantomographic films and the physical examinations of 425 patients (202 males and 223 females) with impacted teeth. The elements that were examined and processed were relevant to the age, sex, total number of impacted teeth, and the type and frequency of impaction of each tooth. Moreover, the associated pathology, if any, of the impacted tooth was recorded. Results: A total of 152 patients (35.8%) had one impacted tooth, 134 patients (31.5%) had two impacted teeth, and 139 patients (32.7%) had three or more impacted teeth; 777 (82.7%) impacted teeth revealed associated pathology. Conclusions: The third molars revealed the highest frequency of impaction (P < 0.001); the number of impacted teeth of the mandible was larger than that of the maxilla (P < 0.001), and the number of impacted anterior teeth in the maxilla was larger than that in the mandible (P < 0.001). Cases of impacted posterior teeth were more numerous than anterior teeth (P < 0.001). The majority of patients revealed pathological signs, which dictated the surgical removal of the impacted tooth/teeth. 相似文献

Tracheostomy is frequently required for
the treatment of critically ill patients to prevent the complications
with prolonged translaryngeal intubation. It may facilitate airway
suctioning and improve patient comfort during the process of weaning.
The purpose of the study was to introduce a new modified technique for
percutaneous dilational tracheostomy (MPDT) and assess its advantages.
From November 1997 through December 2000, a series of 600 patients (350
men, 250 women; mean age 44.5 years) underwent MPDT in our department.
The technique we used is a combination of the Seldinger and Schachner
techniques with an incision of 2 to 3 cm between the cricoid cartilage
and the notch. Using a small automatic retractor, the thyroid muscles
were dissected with the help of a curved mosquito clamp. This gave us
the opportunity to control the isthmus and offered the possibility of
ligation when the thyroid was large, providing a good operative field
directly on the trachea. Hence we avoided traumatizing the isthmus,
which is the main source of hemorrhage during this procedure. The mean
operating time was 4.5 minutes. The morbidity rate was 0.04%. One
patient developed a subcutaneous emphysema and in three cases we had to
ligate the external jugular vein. The surgical incision was completely
healed within 3 to 4 days after removing the tracheostoma. No tracheal
stenoses were observed during the follow-up. MPDT is a safe, applicable
technique that can be performed quickly even by a nonsurgeon in the
intensive care unit and emergency department, with a low risk of
complications because there is a direct view of the trachea and minimal
trauma. 相似文献

Ventricular volume change in childhood 总被引:3,自引:0,他引:3
OBJECT: The aim of this study was to construct a model of age-related changes in ventricular volume in a group of normal children ages 1 month to 15 years, which could be used for comparative studies of cerebrospinal fluid circulation disorders and cerebral atrophy developmental syndromes. METHODS: A magnetic resonance imaging-based segmentation technique was used to measure ventricular volumes in normal children; each volume was then plotted against the child's age. In addition, intracranial volumes were measured and the ratio of ventricular to intracranial volume was calculated and plotted against age. The study group included 71 normal children, 39 boys and 32 girls, whose ages ranged from 1 month to 15.3 years (mean 84.9 months, median 79 months). The mean ventricular volume was 21.3 cm3 for the whole group, 22.7 cm3 in boys and 19.6 cm3 in girls (p = 0.062, according to t-tests). The mean ventricular volume at 12 months for the whole group was 17 cm3 (20 cm3 in boys and 15 cm3 in girls), representing 65% of the volume achieved by 15 years of age (87% in boys and 53% in girls). The volume increased by a factor of 1.53, to 26 cm3 (23 cm3 in males and 28 cm3 in females, increase factors of 1.15 and 1.86, respectively) at 15 years of age. The change in ventricular volume with age is not linear, but follows a segmental pattern. These age periods were defined as: 0 to 3, 4 to 6, 7 to 10, and 11 to 16 years. A statistical difference based on sex was only demonstrated in the first 6 years of life. The mean ventricular volume for the first 6-year period was 22.4 cm3 in boys and 15.7 cm3 in girls, and the difference was significant for the two sexes (linear regression analysis for age and sex, significant according to analysis of variance regression at 0.007, p = 0.108 for age, p = 0.012 for sex). Thereafter, there was no significant difference in ventricular volume between boys and girls with further growth. The ratio of ventricular volume to intracranial volume was 0.0175 for the whole group, 0.017 in boys and 0.018 in girls (p = 0.272, according to t-tests). At 12 months of age the ratio was 0.019; it stabilized to 0.015 at 8 years of age, and increased to 0.018 at 15 years of age. No statistical difference based on sex was demonstrated with growth. CONCLUSIONS: The ventricular volume in normal children increases with age by a factor of 1.5; the increase is in a nonlinear segmental pattern. Boys have significantly higher ventricular volumes only in the first 6 years of life. The ventricular/intracranial volume ratio remains stable throughout childhood. 相似文献
