Sentinel lymph node biopsies in melanoma: how many nodes do we really need? - Annals of plastic surgery
Sentinel lymph nodes (SLN) biopsy is a widely used method to detect lymphatic spread in patients with cutaneous melanoma. Several methods are used to detect SLNs. Recent reports attempted to identify the adequate number of SLNs to reliably detect malignant spread in regional lymph nodes.The radiotracer counts and the pathologic reports of all patients undergoing SLN biopsies were collected prospectively, to determine which of the nodes harboring radiotracer needed to be removed for examination by histopathology between 1998 and 2005. All patients with positive SLN biopsies were investigated in the study. Lymph nodes were ranked according their radiotracer counts and numbered as hottest nodes, second hottest nodes, third hottest nodes, etc. The relationship between radioactivity and the risk of harboring malignancy was determined.Nodal metastases were detected in 55 basins from 53 patients (10.5%). There was a correlation between the radiotracer uptake and risk of harboring malignancy. Excising the 3 hottest nodes and all blue nodes detected 100% of patients with lymphatic malignancy in our series. Most (98%) of positive lymph nodes had radiotracer counts greater than 30% of the hottest node. Only 1 patient (2%) had radioactive count less than 30%, but had visible blue dye.Removing only the hottest node is inadequate to detect lymphatic spread. On the other hand, removing the 3 hottest nodes and all visible blue nodes is sufficient to detect regional lymphatic spread in patients with cutaneous melanoma. Removing nodes with a radiotracer uptake less than 30% of the hottest nodes may be unnecessary.
Staged arterial embolization and surgical resection of a giant splenic artery aneurysm. - Annals of vascular surgery
Splenic artery aneurysms (SAAs) are increasingly being diagnosed as incidental findings. Management modalities include operative treatment, percutaneous embolization, laparascopic ligation, and observation. Giant SAAs larger than 8 cm are a rare entity. We report the case of a 78-year-old woman with an 11 cm SAA who underwent successful percutaneous embolization, followed by surgical excision. We discuss the management of this patient and provide a review of the relevant literature. The approach to SAA should remain individualized.
Clinical pulmonary embolus after gastric bypass surgery. - Surgery for obesity and related diseases : official journal of the American Society for Bariatric Surgery
Pulmonary embolus (PE) is one of the most common causes of death for patients undergoing gastric bypass surgery. The risk of developing PE has been associated with increased age, greater body mass index (BMI), and chronic venous stasis disease.Between 1998 and 2003, 1225 patients underwent open Roux-en-Y gastric bypass (RYGBP) surgery (258 men and 967 women) for the treatment of morbid obesity and its related disorders. The medical records for morbidly obese patients diagnosed with PE after RYGBP were identified. The presenting signs and symptoms were reviewed, and the known risk factors were analyzed. We compared the age and BMI of these patients with those of a randomly selected RYGBP control group. The Mann-Whitney U test was used to analyze the statistical significance of the results.During the study period, 11 patients were diagnosed with PE (0.9%). Six patients were men and five were women, for a gender-specific incidence of PE of 2.3% in men and 0.5% in women. The average BMI was 62.5 kg/m(2) in the men and 59.1 kg/m(2) in the women, much greater than in the control group (men 53 kg/m(2) and women 52 kg/m(2); P <0.005 and P <0.05, respectively). All male patients were super-obese (BMI >50 kg/m(2)). The total number of super-obese patients undergoing RYGBP during the study period was 147, for an incidence of PE in super-obese men of 4%. Nine of the 11 patients developed PE after discharge from the hospital within an average of 10 days.The super-obese male patient is at a much greater risk of developing PE than other RYGBP patients (relative risk 4.4). The risk extends to several weeks after discharge. Therefore, extending PE prophylaxis to several weeks after surgery may be warranted.
Vital capacity as a predictor of outcome in elderly patients with rib fractures. - The Journal of trauma
This study tests the relationships between early bedside vital capacity (VC) measurement and morbidity, mortality, and resource consumption in geriatric blunt chest trauma patients with rib fractures.This was a retrospective study examining all patients > or = 65 years old with rib fractures who had a VC measured within 48 hours of their emergency department evaluation. Outcome variables included pulmonary complications, death from pulmonary complications, hospital length of stay (LOS), intensive care unit length of stay (ICU LOS), and discharge disposition.Thirty-eight patients met the study criteria. The mean age was 80.2 (+/-7.4) years, the mean number of rib fractures was 3.6 (+/-1.6), and the mean ISS was 6.9 (+/-4.7). VC and the percentage of the predicted vital capacity (pVC) were both inversely correlated with LOS (p = 0.0076 and p = 0.0172, respectively). Linear regression analysis suggested that patients with a VC < 1.4 L or < 55% of their pVC had a LOS > 3 days. Mean VC was 36% higher in patients who were discharged home versus those discharged to an extended care facility (ECF; p = 0.025). There was a trend toward significance when comparing VC to ICU LOS (p = 0.079), but none in predicting pulmonary complications (p = 0.3299). No correlations between VC and mortality can be drawn given the single death in the cohort.Bedside VC is a simple measurement which could predict LOS in elderly patients with rib fractures and may identify those patients requiring ECF upon discharge. Further prospective study may highlight the utility of emergency room VC in determining the disposition of these patients.
Effects of delaying appendectomy for acute appendicitis for 12 to 24 hours. - Archives of surgery (Chicago, Ill. : 1960)
To determine whether delaying appendectomy for 12 hours to avoid disturbing the operating room schedule and to minimize the number of operations during the night negatively affects the outcome of patients with acute appendicitis.Retrospective study.Large teaching community hospital.The medical records of 380 patients who underwent appendectomies between January 1, 2002, and December 31, 2004, were reviewed. Patients proven to have an inflamed appendix on the pathological report were divided into 2 groups. The early group comprised patients who had undergone appendectomies within 12 hours of presentation to the emergency department, including patients with generalized sepsis. The late group comprised patients who had undergone appendectomies more than 12 to 24 hours after presentation.Length of stay, operative time, and the rate of perforations and complications.Laparoscopic or open appendectomies.There were 309 patients included in our study. There were no statistically significant differences between the early and late groups in the length of stay, operative time, the percentage of advanced appendicitis, or the rate of complications.In selected patients, delaying appendectomies for acute appendicitis for 12 to 24 hours after presentation does not significantly increase the rate of perforations, operative time, or length of stay. It decreases the use of the nursing staff, anesthesia team, and surgical house staff during the night shifts, and it decreases the interruption of the regular operating room schedule.
Giant lipoma causing a colo-colonic intussusception. - The American surgeon
Intussusception is much more common in children than in adults. Unlike in children, intussusception in adults is associated with an identifiable etiology in 90 per cent of cases. Lipomas are the second most common benign tumors of the colon. Small lipomas are usually asymptomatic and are found incidentally during colonoscopy. Giant lipomas are uncommon causes for colonic intussusception. This usually presents as abdominal pain and vomiting and less commonly as diarrhea. Computed tomography is an excellent method to diagnose giant colonic lipomas, by showing a well demarcated, round, low-attenuated lesion in the lumen of the colon. The definitive treatment for symptomatic lipomas is surgical resection. Both laparoscopic and open resections have been described. Endoscopic resection of colonic lipomas is associated with a high complication rate. In this report, we present a patient with a giant colonic lipoma causing colocolonic intussusception.
Ruptured giant colonic diverticulum. - The American surgeon
Giant colonic diverticulum (GCD) is a rare complication of diverticular disease with less than 150 cases reported in the English literature. The clinical presentation ranges from asymptomatic to that of an acute abdomen. In most cases, giant colonic diverticulum is found in the sigmoid colon. The ideal treatment is elective resection of the sigmoid colon with primary anastomosis. When the diverticulum presents with perforation or obstruction, however, the treatment is a sigmoid colectomy with diverting colostomy (Hartmann procedure).
The mature bone morphogenetic protein-2 is aberrantly expressed in non-small cell lung carcinomas and stimulates tumor growth of A549 cells. - Carcinogenesis
To help identify genes, which may regulate metastasis in lung cancer, we performed representational difference analysis between a patient-derived non-small cell lung carcinoma (NSCLC) and immortalized normal human bronchial epithelial cells. This analysis revealed that bone morphogenetic proteins-2/4 (BMP) mRNA was expressed in the lung carcinoma. BMP-2/4 are known to induce pluripotent cell differentiation, enhance cell migration and stimulate proliferation during embryonic development. Despite being powerful morphogens it is not known whether BMP-2/4 have significant biological activity in human carcinomas. Furthermore, it has not been established whether the mature active BMP-2/4 protein is aberrantly expressed in patient-derived tumors. The purpose of this study was to determine whether the expression of the mature BMP-2/4 protein is disregulated in human lung carcinomas and to establish whether it has adverse biological activity. This study reveals that the mature BMP-2 protein, but not BMP-4, is highly over-expressed in human NCSLC with little to no expression in normal lung tissue or benign lung tumors. The expression of BMP-2 localized specifically to the cancer cells. Recombinant BMP-2 stimulated in vitro, the migration and invasiveness of the A549 and H7249 human lung cancer cell lines. In vivo, recombinant BMP-2 enhanced the growth of tumors formed from A549 cells injected subcutaneously into nude mice. Furthermore, inhibition of BMP-2 activity with either recombinant noggin or anti-BMP-2 antibody resulted in a significant reduction in tumor growth. This study shows that expression of the mature BMP-2 protein is disregulated in the majority of NSCLC. BMP-2 enhancement of tumor cell migration and invasion, as well as stimulating tumor growth in vivo, suggests it has important biological activity in lung carcinomas.
