Late seromas after breast implants: theory and practice.

BACKGROUND: Late seromas surrounding breast implants are becoming an increasingly important issue in breast surgery. The authors report their experience with late seromas and describe their previous management options. METHODS: A multicenter retrospective review of patients who developed late seromas (clinically presenting seromas without evidence of overt or documented infection more than 1 year after implant operation) was performed. Management, surgical technique, outcomes, complications, culture findings, and cytology results were recorded. RESULTS: Between 2005 and 2010, 28 late seromas were identified in 25 patients. The average interval from the patient's last surgery to seroma onset was 4.7 years; 27 of 28 breasts (96 percent) had a Biocell textured device in place at the time of seroma development. The late seromas in the series were managed as follows: 15 (53.6 percent) by complete capsulectomy, seroma drainage, and new implant placement; three (10.7 percent) by seroma drainage and new implant placement but without capsulectomy; two (7.1 percent) by complete capsulectomy and seroma drainage but without implant replacement; five (17.9 percent) by only ultrasound-guided seroma drainage without the need for surgical intervention; and three (10.7 percent) by antibiotic therapy alone. All cultures and cytology studies were negative for malignancy or infection; 27 of 28 seromas (96 percent) were treated successfully by one of the described approaches. CONCLUSIONS: Biocell textured implants were more likely to be associated with late seromas than were smooth shell implants. The overwhelming majority of late seromas appear to be idiopathic, without clear evidence of infection or malignancy. A graduated approach, including several different management strategies, was used to successfully manage these patients. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Breast reconstruction using a staged nipple-sparing mastectomy following mastopexy or reduction.

BACKGROUND: To address those patients who do not meet anatomical criteria for nipple-sparing mastectomy, the authors use a staged approach: (1) mastopexy or breast reduction, (2) nipple-sparing mastectomy through the mastopexy incisions after a minimum of 3 to 4 weeks, and (3) the final reconstruction. METHODS: Fifteen patients underwent nipple-sparing mastectomy at Georgetown University Hospital between 2007 and 2010 after planned or unrelated mastopexy or reduction. An institutional review board-approved retrospective chart review recorded demographic information and outcomes such as skin necrosis and device failure. RESULTS: Fifteen patients (24 breasts) underwent nipple-sparing mastectomy after mastopexy or reduction with an average follow-up of 13 months. The staged procedure was planned in 10 patients [19 breasts (79 percent)] and unplanned, or coincidental, in five [five breasts (21 percent)]. The mastectomy was prophylactic in 17 breasts (71 percent) and therapeutic in seven (29 percent). Four of the 24 operated breasts (17 percent) experienced a complication. Two patients [two breasts (8 percent)] developed skin flap necrosis. Two patients [three breasts (13 percent)] developed minimal partial nipple-areola complex necrosis. One patient [one breast (4 percent)] had an expander explanted for infection related to skin flap necrosis. Fourteen patients [23 breasts (96 percent)] successfully recovered following nipple-sparing mastectomy and prior mastopexy or reduction without residual effects of nipple-areola complex or skin flap necrosis. CONCLUSIONS: The authors are comfortable offering the staged approach to nipple-sparing mastectomy to patients with moderately large or ptotic breasts. It may not be suitable for the very large or ptotic breast. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Advance directives, preemptive suicide and emergency medicine decision making.

As the United States population ages, there is a growing group of aging, elderly, individuals who may consider "preemptive suicide"(Prado, 1998). Healthy aging patients who preemptively attempt to end their life by suicide and who have clearly expressed a desire not to have life -sustaining treatment present a clinical and public policy challenge. We describe the clinical, ethical, and medical-legal decision making issues that were raised in such a case that presented to an academic emergency department. We also review and evaluate a decision making process that emergency physicians confront when faced with such a challenging and unusual situation .

Single port access (SPA) splenectomy.

INTRODUCTION: Over the last decade, laparoscopic splenectomy has become the standard of care for spleen removal. Elimination of a large incision and difficult exposure has decreased postoperative morbidity and length of stay. Single port access (SPA) surgery was developed as an alternative to traditional multiport laparoscopy, potentially exploiting the already proven benefits of minimally invasive surgery. We apply the SPA technique to splenectomy via a single umbilical incision. METHODS: SPA splenectomy was performed in a 36-year-old male for staging. The single-port access technique was used to gain abdominal entry. Exposure, dissection, and removal were performed via a single incision within the umbilicus. The final incision was extended for removal of a complete specimen for pathologic evaluation. RESULTS: Splenic mobilization and control of the short gastrics was successfully performed via a single umbilical incision. The final incision was extended inferiorly for en bloc organ removal. Follow-up at 18 months revealed a well-healed incision with no signs of hernia formation. CONCLUSIONS: The single-port access technique has been successfully applied to splenectomy as an available alternative to multiport laparoscopic splenectomy. Use of standard instrumentation and trocars maintains costs and familiarity of the procedure. Exposure, visualization, and dissection are the same as in standard laparoscopy. SPA surgery may be more ergonomically pleasing to the surgeon and offer patient benefits, such as faster recovery and decreased adhesion formation in the long term.

A graduate curriculum in emergency public health.

The increase in adverse health impacts of disasters has raised awareness of the need for education in the field of emergency public health. In the past, most traditional models of graduate education in schools of public health have not incorporated the theory and practice of disaster public health into their curricula. This paper describes the development of a curriculum in emergency public health within a US masters program in public health, and provides a description of the courses that comprise an area of specialization in the field. The interdisciplinary nature of the faculty, close ties with public health practitioners, and practical applications of the nine courses in this program are highlighted. The curriculum is presented as one model that can be used to meet the educational needs of professionals who will assume the responsibility for planning for and responding to the public health impacts of mass-populations disasters.

Pandemic influenza triage in the clinical setting.

INTRODUCTION: There has been much federal and local health planning for an influenza pandemic in the United States, but little is known about the ability of the clinical community to deal quickly and effectively with a potentially overwhelming surge of pandemic influenza patients. PROBLEM: The attitudes and expectations of emergency physicians, emergency nurses, hospital nursing supervisors, hospital administrators, and infection control personnel concerning clinical care in a pandemic were assessed. METHODS: Key informant structured interviews of 46 respondents from 34 randomly selected emergency receiving hospitals in Los Angeles County were conducted using an Institutional Review Board-approved protocol. The interview asked about supplies/resources, triage, quality of care, and decision-making. At the conclusion of each interview, the informant was asked to provide the contact information for at least two others within their respective professional group. Interviews were transcribed and coded for key themes using qualitative analytical software. RESULTS: There was little salience that an influx of variably ill patients with influenza would force stratified healthcare decision-making. There also was a general lack of preparation to address the ethics and practices of triaging patients in the clinical setting of a pandemic. CONCLUSIONS: Guidelines must be developed in concert with public health, medical society, and legislative authorities to help clinicians define, adopt, and communicate to the public those practice standards that will be followed in a mass population, infectious disease emergency.

Single Port Access (SPA™) Minimal Access Surgery Through a Single Incision.

The practice of surgical techniques is constantly improving and evolving. In the last two decades, minimally invasive surgery has gained widespread acceptance. Virtually all procedures can now be performed laparoscopically. This trend not only provides better cosmesis, but offers decreased recovery times as well. The initial trend from open to laparoscopic surgery was to use smaller incisions. The natural continuation of this is to now decrease the number of incisions necessary to perform minimal access surgery. To this end, the authors have seen a constantly evolving stream of technology and instrumentation in laparoscopy. New venues, such as robotics and Natural Orifice. Transluminal Endoscopic Surgery (NOTES), have developed as well. As part of this evolution, the authors developed Single Port Access (SPA™) surgery in April 2007 as a novel and innovative platform of minimal access surgery. Its acceptance through our training programs, as well as the subsequent development of modified Single Port techniques, demonstrates the potential to develop a new platform of minimal access surgery. The SPA™ technique is a method of abdominal entry for a wide spectrum of laparoscopic procedures performed by multiple surgical specialties. Using the access techniques we developed, the authors have performed nearly 200 general surgical and gynecologic procedures through a single incision, often <2 cm in length and hidden within the umbilicus. In addition, the development of SPA™ surgery has been focused on using current and standard instrumentation, as well as currently practiced surgical techniques already familiar to surgeons in standard multiport laparoscopy. The "Independence of Motion" attained in this access technique, without the need for any new access or operative devices, allows up to four instruments to be place through a single incision<2 cm in length. We have striven to maintain safety principles of multiport laparoscopy, as well, and have continued to improve the technique to increase the availability and broad application of SPA™ surgery. Out technique and its application, across a broad range of surgical procedures and surgical specialties, are presented herein.

Single port access (SPA) cholecystectomy: a completely transumbilical approach.

We have seen substantial changes in minimally invasive surgery since its development in the early 1900s. Over the past 10 years, the addition of natural orifice transluminal endoscopic surgery and robotics has turned our attention to improved cosmesis and advancements in instrumentation. We have developed a new technique-single port access (SPA) surgery-and have applied it to the cholecystectomy. In this paper, we present and review the application of this access technique to the first 5 consecutive patients that underwent an SPA cholecystectomy. All 5 patients were female, with an average age of 45 years and an average weight of 172 pounds. Indications included biliary dyskinesia and symptomatic cholelithiasis. Average operative time was 121 minutes in these initial 5 cases. All but 1 patient was discharged in 24 hours. At 6 months, no umbilical hernias were observed. This new technique allows for a complete cholecystectomy to be performed entirely through the umbilicus without the need for additional retraction sites or transabdominal sutures. This procedure utilizes the same basic technique of the laparoscopic cholecystectomy already employed by general surgeons. Therefore, the SPA cholecystectomy can be readily learned and performed by many surgeons without the need for expensive or experimental equipment. Using a single portal of entry to the abdominal cavity, the umbilicus, cosmesis, and scar reduction is achieved.

Single Port Access (SPA) gastrostomy tube in patients unable to receive percutaneous endoscopic gastrostomy placement.

BACKGROUND: Access procedures for alimentation have been performed both endoscopically and surgically. In those patients in whom endoscopic tubes cannot be placed, the minimally invasive approach is a viable alternative. To minimize incisions and their sequelae, we have developed a single port access (SPA) technique in which minimal access surgery can be done through one portal of entry, often the umbilicus. METHODS: We have used the SPA technique to place gastric feeding tubes in patients who are not candidates for PEG tubes due to supraglottic stenosis. We reviewed our experience in the first five procedures we performed. RESULTS: In all five patients a gastrostomy tube was placed laparoscopically via an umbilical incision and a left-upper-quadrant tube insertion point. Mean operative time was 44 min. All patients began tube feeds on postoperative day 1. CONCLUSION: We present the first series of five SPA gastric tube placements, offering a viable alternative to PEG or open placement.

Single port access (SPA) cholecystectomy: two year follow-up.

INTRODUCTION: Laparoscopy is a constantly evolving field of surgery. New technology, applications, and benefits prompt continual improvement. We have developed a Single Port Access (SPA) surgical technique that allows for the entire cholecystectomy to be performed through a single incision within the umbilicus while maintaining safe standard dissection and retraction techniques of currently performed multiport laparoscopic cholecystectomy. METHODS: Fifteen consecutive patients underwent SPA cholecystectomy. Indications were cholelithiasis, cholecystitis, CBD stones, and biliary akinesia. The entire procedure was performed through a single umbilical incision measuring <1.8 cm within the umbilicus. Three trocars and a rigid grasper were inserted through separate fascial sites within the same skin incision. The cholecystectomy procedures are then performed in the standard fashion described in multi-port cholecystectomy. RESULTS: Fifteen patients successfully underwent Single Port Access cholecystectomy. One patient required a second 5-mm port site secondary to difficulty with retraction of a large liver. Operative times averaged 107 minutes. Blood loss, patient recovery, and outcomes have been comparable to those of standard multi-port procedures. No umbilical hernias have been seen at 2 years of follow-up. CONCLUSION: We present the SPA cholecystectomy as an alternative to multi-port cholecystectomy. In the first 2 years, SPA surgery has evolved into a technique easily taught and performed without the restrictions of new equipment or added cost.

Extramedullary versus intramedullary tibial alignment guides for total knee arthroplasty.

This retrospective study evaluated whether intramedullary or extramedullary tibial alignment guides are more accurate in assuring correct tibial component positioning in total knee arthroplasties (TKAs). Fifty-five TKAs were performed with the only difference being whether an intramedullary (31) or extramedullary (24) cutting guide was used. Pre- and postoperative tibiofemoral angle, tibial component alignment angle, and femoral component alignment angles were measured and the results were statistically analyzed. We also performed a subgroup analysis on the preoperative varus knees to determine if the presence of a varus deformity would have better results with either the intramedullary or extramedullary cutting guide. The 2-sample t test was used to compare the results of the two groups. The results showed no statistical difference in alignment of the tibial component when using the intramedullary or extramedullary guides.

Development of a training curriculum for public health preparedness.

We describe the development of a 2-day training curriculum in emergency public health to improve the competency of public health personnel to prepare for, and respond to, both natural and human-caused disaster hazards. The training is conducted in a face-to-face setting and content is mapped to recognized emergency preparedness competencies for public health workers. The training materials are uniquely structured to the specific hazards, demographics, resources, and local emergency response agencies for each jurisdiction. This training program incorporates a series of challenging interactive scenarios that reinforce decision making in a public health emergency. Pretesting and posttesting are used to evaluate knowledge gained by participants. This interactive approach aligns with the principles of adult learning, and training evaluations indicate that this method is an effective integration of process and content.
