Late results of a simple closure technique and Helicobacter pylori eradication in duodenal ulcer perforation.

BACKGROUND AND AIM: The aim of this study is to determine the incidence of Helicobacter pylori (H. pylori) in patients operated on for duodenal ulcer perforation and to evaluate the late results of a simple closure technique in patients positive and negative for H. pylori. METHODS: The data of 84 patients who underwent simple closure for duodenal ulcer between 2003-2007 were retrospectively studied. Antral biopsy material taken from all patients during laparotomy was studied with the rapid urease test and the patients were then separated into 2 groups. Group 1 (H. Pylori positive) received postoperative H. pylori eradication treatment, and Group 2 (H. pylori negative) received only lansaprasol treatment after surgery. All patients were evaluated with upper gastrointestinal endoscopy on the 6th and 14th postoperative weeks. Primary treatment failure was considered in patients who had non-healing ulcers after 14 weeks. Patients with healed ulcers were scheduled for annual examinations. The results were compared between the groups. RESULTS: The rate of H. pylori infection in duodenal ulcer perforation was found to be 80.9%. Ulcer healing rates on the postoperative 6th and 14th weeks were 88.2% and 97.5% in the first group, and 68.8% and 81.2% in the second group, respectively. Mean postoperative follow-up was 41.28 +/- 17.63 (range 17-73) months. Ulcer recurrence rate was found to be 4.54% in Group 1 and 30.76% in group 2 (p = 0.012). CONCLUSIONS: All patients with a perforated peptic ulcer should be treated with simple closure of the perforation followed by medical therapy aimed at healing the ulcer. We believe that H. pylori negative patients have more risk of recurrence and such patients require close postoperative follow-up.

A rare cause of intestinal obstruction: incarcerated femoral hernia, strangulated obturator hernia.

Obturator hernia may occur bilaterally in association with another hernia, which is usually of the femoral type. We present a 77-year-old-woman who had abdominal pain with nausea and vomiting together with swelling of the right groin for 3 days. Incarcerated right femoral hernia and consequent mechanical small-bowel obstruction was diagnosed, and urgent operation was undertaken. As the incarcerated femoral hernia reduced spontaneously during the induction of anesthesia, a lower median incision was performed. During exploration, the real cause of mechanical intestinal obstruction was found to be a small intestinal loop strangulated in the left obturator hernia. Right femoral and left obturator hernia were repaired with preperitoneal polypropylene mesh. If there is enough time and general condition of the older patient is suitable, further diagnostic techniques for concomitant obturator hernias may be useful in patients who present with signs of incarcerated inguinal hernia and intestinal obstruction.

The role of pre-operative B mode ultrasound in the evaluation of the axillary lymph node metastases in the initial staging of breast carcinoma.

The lymph node status of a breast cancer is one of the main prognostic criterias. This status is very important to determine the therapeutic approach. Physical examination alone is not sufficient to assess axillary metastases. Mammographic examination can give us an idea about breast cancer and axillary involvement. Ultrasonographic evaluation can improve the sensitivity of clinical and mammographic examination in assessing axillary lymph node status. 42 patients operated on for breast cancer between January 2000-January 2003 were included in this prospective study. In the study, we used axillary B mode ultrasound to evaluate the axillary lymph nodes. There are several sonographic features to categorize them. Axillary B mode ultrasound was performed to evaluate the axillary lymph nodes for metastatic involvement. In the evaluation of lymph nodes, the sonographic criteria were centric echogenity, thickening of cortex, length/width ratio (L/W) and the diameter of lymph nodes. Hyperechogenic hilus was accepted as a benign finding. The thickening of the cortex less than 50% of the thickening of the centric echogenic hilus was also accepted as a benign finding. L/W ratio below 2 and parameters above 2 cm were accepted as malignant findings. 168 lymph nodes in 42 patients were evaluated pre-operatively with axillary B mode ultrasound. As a result, these lymph nodes were defined as benign in 19 patients (45.2%) and malignant in 23 patients (54.8%). Axillary lymph node status was found as benign in 18 patients (42.9%) and malignant in 24 patients (57.1%) pathologically . Comparative results of ultrasound and axillary lymph node status can be seen on Table III. As a result, the sensitivity of axillary B mode ultrasound to show the metastases was found as 79.1%, specificity was 77.7%, positive predictive value 82.6% and negative predictive value 73.6%. We think some better results may be obtained in the future and these developments may affect the surgeon's decisions concerning axillary dissection for breast cancer operations.

Primary T-lymphoma of the breast with bilateral involvement, unusual presentation.

Primary or secondary involvement of the breast is a rare form of extranodal lymphoma. Most reported primary non-Hodgkin lymphomas of the breast have a B-cell phenotype, those of T-cell phenotype are even more rare. Bilateral breast involvement at diagnosis also is very rare. We herein report a young female patient with bilateral breast involvement by low-grade T-cell malignant lymphoma.

Usefulness of 99mTc-ciprofloxacin (infecton) scan in diagnosis of chronic orthopedic infections: comparative study with 99mTc-HMPAO leukocyte scintigraphy.

UNLABELLED: 99mTc-labeled ciprofloxacin (infecton) has been developed for detecting infectious foci, which localize in high concentrations in living bacteria. Other studies performed with various infections in animals and humans have found that infecton is a promising agent with better specificity for bacterial infections than white blood cell (WBC) scans. In this study, we evaluated the efficacy of infecton scintigraphy for detecting chronic bone and joint infections. METHODS: Fifty-six sites with suspected bone or joint infection were examined with 99mTc-WBC and infecton scans in 51 patients. Of these patients, 21 had prosthetic implant materials. Biochemical, radiologic, and microbiologic data and clinical outcomes also contributed, along with the results from scintigraphic techniques, in determining the presence or absence of infection. Scintigraphic images were produced at 1 and 4 h after injection of 370-400 MBq infecton or 185-200 MBq 99mTc-hexamethylpropyleneamine oxime (HMPAO)-WBCs. For each patient, there were at least 2 d and at most 7 d between scintigraphic studies. RESULTS: There were 30 true-positive, 4 false-positive, 20 true-negative, and 2 false-negative results with infecton. With 99mTc-HMPAO-WBCs, the results were 20, 1, 23, and 12, respectively. Values for sensitivity, specificity, and accuracy were 94%, 83%, and 89%, respectively, with the infecton scan and 63%, 96%, and 77%, respectively, with WBC scanning. Differences between the two agents were statistically significant (P < 0.001). Infecton and WBC scan results were in general concordance for 43 of 56 sites (77%). Infecton results for vertebral infections were the most notable findings in this study, despite the limited number of patients with this condition. Infecton scans were positive for hot spots in five of six patients with vertebral osteomyelitis. WBC scans showed photon-deficient areas in four of these same patients and normal distribution in the remaining two patients. CONCLUSION: Infecton is a useful agent for detecting infectious foci in bones and joints. Moreover, the infecton scan seems to be a more powerful tool in diagnosing vertebral infections than WBC scintigraphy.

Can negative appendectomy rate be decreased by using spiral computed tomography without contrast material?

Approximately 15-20% of error in the diagnosis of acute appendicitis argues for new diagnostic methods. In recent years it has been proposed that Computed Tomography be used in the diagnosis of acute appendicitis with high sensitivity and specificity. In our study, the effect of Computed Tomography on the diagnosis of acute appendicitis and on negative appendectomy was investigated on patients with suspected acute appendicitis. In the last 18 months, spiral Computed Tomography without contrast material has been used for 65 patients. The history, physical findings, laboratory results and Computed Tomography images of patients were compared and the final decision to operate was always made by an attending surgeon. The results of Computed Tomography have been correlated with the reports of pathology and operation findings. Other patients who have not been operated on have been followed up clinically. Correlating Computed Tomography results with operation findings revealed; 42 true positive, 3 false positive, 17 true negative and 3 false negative results. The sensitivity and specificity of CT have been found to be 93.3% and 85% respectively. Forty-eight out of 65 patients have been operated on for acute appendicitis and the negative appendectomy rate has been calculated as 6.25%. As a consequence, it was thought that in the diagnosis of acute appendicitis the use of Computed Tomography could decrease the negative appendectomy rate when used together with clinical follow-up.

Effects of sedation during upper gastrointestinal endoscopy on endocrine response and cardiorespiratory function.

Upper gastrointestinal endoscopy is often accompanied by tachycardia which is known to be an important pathogenic factor in the development of myocardial ischemia. The pathogenesis of tachycardia is unknown but the condition is thought to be due to the endocrine response to endoscopy. The purpose of the present study was to investigate the effects of sedation on the endocrine response and cardiorespiratory function. Forty patients scheduled for diagnostic upper gastrointestinal endoscopy were randomized into 2 groups. While the patients in the first group did not receive sedation during upper gastrointestinal endoscopy, the patients in the second group were sedated with intravenous midazolam at the dose of 5 mg for those under 65 years or 2.5 mg for those aged 65 years or more. Midazolam was administered by slow infusion. In both groups, blood pressure, ECG tracing, heart rate, and peripheral oxygen saturation (SpO2) were monitored during endoscopy. In addition, blood samples for the determination of cortisol, glucose and C-reactive protein levels were obtained from patients in both groups prior to and following endoscopy. Heart rate and systolic arterial pressure changes were within normal limits in both groups. Comparison of the two groups regarding the values of these two parameters did not reveal a significant difference, while a statistically significant reduction in SpO2 was found in the sedation group. No significant differences in serum cortisol, glucose or C-reactive protein levels were observed between the sedated and non-sedated group. Sedation with midazolam did not reduce the endocrine response and the tachycardia developing during upper gastrointestinal endoscopy, but increased the reduction in SpO2.

Myositis ossificans in early childhood.

A 5-year-old boy underwent arthroscopic surgery because of a lateral discoid meniscus, which was followed by an overly strenuous rehabilitation program. At 6-week follow-up, a painful mass at the distal part of the thigh and a flexion restriction of the operated knee were detected, caused by myositis ossificans inside the vastus medialis muscle. The symptoms disappeared with an appropriate rehabilitation program and the patient recovered.

Bilateral discoid medial menisci: an adult patient with symmetrical radial tears in both knees.

A discoid meniscus is a thick meniscus, discoid in shape rather than having the normal semilunar configuration. Discoid meniscus is considered an uncommon lesion; discoid medial meniscus is rare and involvement of the medial meniscus bilaterally is extremely rare. This is the first case report of bilateral discoid medial menisci with symmetrical radial tears. The patient was treated successfully by excision of the central anomalous discoid portion of the menisci, using arthroscopic techniques.

Navigation for ankle arthroscopy: anatomical study of the anterolateral portal with reference to the superficial peroneal nerve.

We aimed to navigate the surgeon regarding the localization of the main anatomical structures at the anterior part of the ankle joint, in order to find easily the safest anatomical points with reference to the superficial peroneal nerve (SPN), in particular for anterolateral portal placement in ankle arthroscopy. Sixty-three ankles in 36 fresh cadavers were dissected. In all specimens we examined (1) the distance between the SPN bifurcation and the most distal point of the lateral malleolus; and at the level of ankle joint, (2) the number of SPN, (3) the distance between the medial and intermediate dorsal cutaneous nerves, which are branches of the SPN, (4) the localization of the peroneus tertius (PT) tendon in relation to the lateral malleolus, (5) the width of the extensor digitorum longus (EDL) tendon, (6) the relationship of the PT tendon and (7) the relationship of the extensor hallucis longus (EHL) tendon with the SPN. The results were as follows: (1) In 41 ankles with bifurcation (65%) the average distance was 71.8+/-35.3 mm. (2) There were two SPN branches in 39 (62%), three branches in seven (11%) and one branch in 17 (27%) cases. (3) In 39 ankles with two branches of the SPN, the mean distance was 15.2+/-7.1 mm. (4) The lateral border of the PT tendon was positioned a mean distance of 20.8+/-3.3 mm proximal and 25.2+/-5.8 mm medial to the reference points. (5) The mean width was 10.1+/-2.9 mm. (6) In 42 ankles (67%) the distance between the lateral border of the PT tendon and the SPN was a mean of 6.2+/-6.6 mm, median of 3 mm (range 0-22 mm lateral to the tendon). (7) In 56 cases (89%) a branch of the SPN was found a mean of 6.6+/-4 mm and a median of 6 mm lateral to the EHL tendon, and in seven cases (11%) on the tendon. According to our study, in ankle arthroscopy the risk of the SPN injury is maximal in the 0-3 mm lateral to the PT tendon. To avoid injury to the SPN, the safest placement of the anterolateral portal is 4 mm lateral to the PT tendon.
