Introduction
The gold standard for treating transverse olecranon fractures is tension band fixation. A problem with this technique is migration of the K-wires leading to premature hardware removal. The aim of this study is to compare stability provided by two new techniques designed to eliminate the problem with backing out of K-wires, with that of the recommended tension band technique, performed with a biomechanical in vitro investigation. Our hypothesis was that the two new techniques would provide at least equal stability as the traditional tension band fixation. 相似文献962.
Axillary lymph node status is the most important prognostic factor in the treatment of breast cancer. In recent years, sentinel
lymph node biopsy (SLNB) has replaced conventional axillary lymph node dissection for predicting axillary lymph node status
with higher accuracy. Moreover, neoadjuvant chemotherapy (NAC) is being used increasingly to treat not only patients with
locally advanced inoperative breast cancer, but also those with initially operable breast cancer. The application of SLNB
has now expanded to include this patient population, who were not previously considered good candidates for SLNB. A number
of recent studies have evaluated the feasibility and accuracy of SLNB after NAC in breast cancer patients. Moreover, SLNB
has been shown to be accurate in patients scheduled to receive NAC, and repeat SLNB has been performed after NAC for patients
with positive nodes detected by the initial SLNB before NAC. Thus, the optimal timing of SLNB for patients with breast cancer
in the neoadjuvant setting remains controversial. This article reviews the issues surrounding SLNB before vs. after NAC, according
to the published literature and our experience. 相似文献

Purpose
Gastrojejunostomy is often performed as palliative surgery for unresectable pancreatobiliary cancer. Modified Devine exclusion (MDE) is a technical variation of gastrojejunostomy, which partially separates the mid-portion of the stomach. We conducted this study to assess whether MDE is necessary for gastrojejunostomy in patients with unresectable pancreatobiliary cancer. 相似文献964.

Posterior dislocation of the shoulder is a rare clinical entity with incidence of 6 per 1,000,000. It is more common in middle-aged men [1] and more than half of all cases may initially be missed [2]. Posterior shoulder dislocation is related to internal rotation, flexion, and abduction forcing of the shoulder secondary to grand mal seizure, electric shock, or trauma [3]. One case of posterior dislocation secondary to a seizure caused by a brain tumor has been reported [4]. Bilateral anterior dislocation because of hypoglycemic coma is very rare [5], and, to our knowledge, no case reports of bilateral posterior shoulder dislocation owing to hypoglycemic coma have been published. 相似文献

Although the appendix has been recognized as a preferential site for carcinoid tumors in obese patients, no definitive guidelines are so far available regarding the management of these patients when candidates for bariatric surgery. This study was designed to fill that gap. Between 2000-2008, 558 patients underwent bariatric procedures. Appendectomy was routinely performed in 477 cases. Their charts were retrospectively retrieved and histopathology responses on surgical specimens were recorded. We aimed to assess: incidence of appendix carcinoid tumors (ACTs) and any possible risk-factor; modality of diagnosis (pre-, intra- or post-operatively); impact on the planned bariatric procedure; treatment reserved to such cases. Typical ACTs were diagnosed in 7 patients (1.4%) (median age: 33 years; median BMI: 49 kg/m2; males/females: 1/6). Four were diagnosed intra-operatively. Because of dimensions (<2 cm) and absence of mesoappendiceal or serosal involvement, simple appendectomy was performed during bariatric procedure, as planned. Three were diagnosed post-operatively (all <2 cm). In 1 case right hemicolectomy was performed 1 month later due to mesoappendiceal involvement. No appendectomy-related complication was encountered. All patients remained tumor-free during follow-up (mean: 64 months; range, 25-92). Young age, female sex, high BMI and diabetes mellitus resulted significantly associated with ACT. Our study sustains routine appendectomy or at least careful investigation of the appendix during bariatric surgery. For tumors <2 cm without mesoappendiceal or serosal involvement, simple appendectomy proved sufficient. Bariatric surgery did not have a negative effect on the treatment of malignancies that are discovered intra- or post-operatively. 相似文献

Laparoscopic adjustable gastric banding (LAGB) is an often performed bariatric procedure for morbid obesity. Several complications are known, including surgery and port-side-associated complications. As rare but serious late complication of LAGB, we describe a 50-year-old patient with periodic incomplete intestinal constriction due to the silicone connecting tube, 4 years after laparoscopic adjustable gastric banding was performed. Abdominal CT scan showed an obstructive ileus due to a loop in the connecting tube. After surgical removal of the connecting tube, the patient recovered without sequelae. 相似文献
