Laparoscopic and thoracoscopic Ivor Lewis esophagectomy after Roux-en-Y gastric bypass.

Roux-en-Y gastric bypass is a commonly performed procedure for the treatment of morbid obesity. Esophagectomy in patients with a history of Roux-en-Y gastric bypass presents a difficult technical challenge for the surgeon. In this report we describe a technique of minimally invasive Ivor Lewis esophagogastrectomy in a patient who had had an open Roux-en-Y gastric bypass. Minimally invasive esophagectomy was performed with resection of the Roux limb using the gastric remnant as the conduit for gastrointestinal reconstruction.

Clinical significance of type II endoleak after endovascular repair of abdominal aortic aneurysm.

Type II endoleaks after endovascular repair of abdominal aortic aneurysm (EVAR) are a result of retrograde flow from arterial branches (e.g., lumbar and inferior mesenteric) refilling the aneurysm sac, which has been excluded by the stent graft. Controversy continues with regard to the clinical significance and treatment of type II endoleaks. To develop recommendations for management, we analyzed outcome data from 10 EVAR trials completed over the last 5 years involving a total of 2,617 cases. The incidence of type II endoleak at discharge or 30 days was 6-17%, at 6 months 4.5-8%, and at 1 year 1-5%. Successful resolution of endoleak following secondary interventions was observed in 11-100% of cases. There were 10 conversions to open repair and no ruptures related to type II endoleak. In patients observed for 12 months with computed tomography and/or ultrasound, approximately one-half of type II endoleaks disappeared spontaneously. In the absence of a type I endoleak, our analysis of the current literature suggests that intervention for type II endoleak should be undertaken for abdominal aortic aneurysm sac enlargement occurring after 6 months, persistence for >12 months without abdominal aortic aneurysm sac enlargement, or an aneurysm sac pressure >20% of systolic blood pressure; translumbar aneurysm sac thrombosis and intra-arterial feeding vessel occlusion appear to be prudent management options.

The surgeon and AIDS: twenty years later.

BACKGROUND: Since the first reports on indications and outcome for abdominal procedures in the HIV/AIDS patient were published 20 years ago, the epidemiology and presentation of surgical illness have changed remarkably with the advent of new antiviral regimens. A review of the now occasional, but still important, role of the surgeon in contemporary treatment of HIV/AIDS is presented. DATA SOURCES: Information was obtained by PubMed searches of medical journals, examination of reference lists, and Web resources. STUDY SELECTION: Articles on operative indications, outcomes, precautions, source of transmission, and pathophysiology of HIV/AIDS were selected. DATA EXTRACTION: Data was obtained from peer-reviewed articles and references. DATA SYNTHESIS: The last 2 decades have seen a decrease in operative mortality from as high as 85% to approximately 15% with a corresponding improvement in morbidity. Surgical emergencies such as appendicitis occur in HIV patients with the same frequency as non-HIV patients and are treated with equivalent results. Concern about transmission of HIV in the operating room has lessened somewhat. Although still a hazard, the probability of HIV transmission with accidental exposure is low, with risks below 0.5% for percutaneous hollow-bore needles and less than 0.1% risk for mucus membrane exposure. CONCLUSIONS: Improved surgical outcomes together with of accurate data on the modes and likelihood of accidental transmission of HIV to members of the surgery team have resulted in the treatment of HIV/AIDS patients becoming an accepted part of routine surgical practice.

Staged laparoscopic Roux-en-Y: a novel two-stage bariatric operation as an alternative in the super-obese with massively enlarged liver.

In a subset of super-obese patients, the one-stage laparoscopic Roux-en-Y gastric bypass (RYGBP) can be associated with significant morbidity and mortality. In a previous effort to reduce the perioperative risks associated with the super-obese, a two-stage operation was devised. This two-stage operation consisted of a sleeve gastrectomy (1st stage) followed by a RYGBP or duodenal switch procedure (2nd stage). We find that the primary limiting factor making laparoscopic gastric bypass challenging in the super-obese is the volume of the left lobe of the liver. A greatly thickened left lobe of the liver obscures visualization of the gastroesophageal junction and angle of His so that a sleeve gastrectomy is difficult to construct. In this report, we describe a novel method utilizing a staged Roux-en-Y procedure. Instead of performing a restrictive operation (sleeve gastrectomy) as the initial procedure, we fashion a modified Roux-en-Y with a low gastrojejunal anastomosis and a larger gastric pouch encompassing the gastric fundus. The low anastomosis obviates the need for exposure of the gastro-esophageal junction and angle of His. At the 2nd stage procedure, completion sleeve gastrectomy of the gastric fundus is performed at an interval of 6-12 months after the 1st stage operation.

Effect of the 80-hour workweek on resident burnout.

HYPOTHESIS: With the introduction of the newly mandated restrictions on resident work hours, we expected improvement in subjective feelings of personal accomplishment and lessened emotional exhaustion and depersonalization. DESIGN: Residents and faculty members completed an anonymous online Maslach Burnout Inventory Human Services Survey (3rd ed; Consulting Psychologist Press Inc, Palo Alto, Calif) and work-hour registry before and after implementation of new restrictions. SETTING: Urban, university-based department of surgery. PARTICIPANTS: All house staff (n = 37) and faculty (n = 27). INTERVENTION: Introduction of new Institutional Standards for Resident Duty Hours 2003. Main Outcome Measure Resident work hours and levels of emotional exhaustion, perceived degree of depersonalization, and personal accomplishment. RESULTS: Resident work hours per week decreased from 100.7 to 82.6 (P < .05) with introduction of the new schedule. Home call and formal educational activity time within working hours (eg, clinical conferences) significantly (P < .05) decreased from 11.5 and 4.8 hours to 4.6 and 2.5 hours per week, respectively. Operating room hours, clinic time, and duration of rounds did not show a significant change. Changes in parameters of resident and faculty emotional exhaustion, depersonalization, and personal accomplishment did not show statistical significance (P > .05). CONCLUSIONS: Despite successful reductions in resident work hours, measures of burnout were not significantly affected. However, important clinical activities such as time spent in the operating room, clinic, and making rounds were maintained. Formal in-hospital education time was reduced.

Laparoscopic Roux-en-Y gastric bypass vs. laparoscopic adjustable gastric banding for treatment of morbid obesity.

Bariatric surgery is a rapidly growing discipline in General Surgery. Roux-en-Y gastric bypass (GBP) is currently the most commonly performed bariatric surgical procedure for treatment of morbid obesity in the United States (U.S). The laparoscopic approach to (GBP) has led to a greater acceptance for surgical treatment of morbid obesity by the public and, in return, more surgeons are becoming interested in learning laparoscopic bariatric surgery to meet the high demand. Laparoscopic adjustable silicone gastric banding was approved in the U.S. by the Food and Drug Administration (FDA) for clinical use in 2001, and is emerging as an alternative laparoscopic option in management of morbid obesity. This chapter reviews the indications, techniques, and outcomes of laparoscopic GBP vs. laparoscopic adjustable gastric banding. The advantages and disadvantages of laparoscopic adjustable gastric banding compared to laparoscopic GBP is discussed.

Choosing general surgery: insights into career choices of current medical students.

HYPOTHESIS: The number of unfilled general surgery programs in the United States increased from 4 in 1999 to 41 in 2001. This study seeks to determine if changes in student attitudes occurring during their medical school careers and during the third-year general surgery clerkship contribute to a decline in interest in a surgical career. DESIGN: Prospective survey of medical students at a public medical school in California. PARTICIPANTS AND METHODS: Each medical student received a survey via the Internet. Responses were anonymous. Once quantified, chi(2) analysis was used for comparison and analysis of survey results. Comparisons were made between individual class years and on the basis of whether the respondent completed the third-year general surgery clerkship. RESULTS: Of 368 surveys sent, 232 (63%) were successfully completed and included in the study. Comparison of students' attitudes before and after completion of their general surgery clerkship showed that following surgical course exposure more students believed surgery lacked breadth of expertise, limitations over stress, control over one's time, regularity of schedule, adequacy of leisure time, and income commensurate to workload (P<.05). These results are also consistent in comparisons between individual class years. CONCLUSIONS: Data suggest that medical students seem to be more concerned with issues of "controllable lifestyle" such as adequacy of family and/or leisure time, high level of stress, and amount of work and commitment. The erosion of income differential between demanding and less taxing specialties was also an important cause cited for the flagging interest in surgical disciplines.
