Defining and predicting surgeon utilization at forward surgical teams in Afghanistan.

BACKGROUND: The forward surgical team (FST) is the US Army's smallest surgical element. These teams have supported current conflicts since 2001. The purpose of this study was to determine if surgeon utilization varied at two different FSTs and to determine factors that may predict the need for a surgeon. METHOD: Data from two FSTs were reviewed. A t-test was used to compare the military injury severity scores (mISS) and the revised trauma scores (RTS). χ(2) analysis was used to compare types and mechanisms of injury and to compare life- or limb-saving surgeries (LLSS) and life-saving interventions among the FSTs. Logistic regression was used to determine if mISS, RTS, physiologic parameters, or laboratory values predicted the need for LLSS or life-saving intervention. RESULTS: The 541st FST treated a larger volume of patients than the 772nd FST (n = 761 versus n = 311). The 772nd FST performed a significantly higher percentage of LLSS; however, absolute number of LLSS was 31 at both FSTs. The mISS among operative patients were similar, but RTS were significantly different (772nd FST = 7.28 versus 541st FST = 7.58, P = 0.008). The 772nd FST saw a higher percentage of motor vehicle collision and rocket-propelled grenade injuries and thoracic and neurologic injuries, and the 541st FST saw a higher percentage of blast and gunshot wound injuries and abdominal injuries. Lactate level was the most significant predictor of the need for LLSS. CONCLUSION: Although percentage of surgical interventions varied between the two FSTs, the absolute number of needed surgical interventions was the same and was small. Lactate level predicted the need for surgical intervention in our population.

Algorithm to diagnose etiology of hypoglycemia after Roux-en-Y gastric bypass for morbid obesity: case series and review of the literature.

BACKGROUND: Gastric bypass is a proven treatment option for weight loss and the reduction of medical co-morbid conditions in the obese population. Severe refractory and/or recurrent hypoglycemia can occur, especially in postoperative patients who do not comply with the guidelines for oral glucose consumption. In a very small number of patients, the cause is not dietary indiscretions but, instead, factitious insulin administration or nesidioblastosis. The optimal evaluation and management for these diagnoses is not completely lucid yet important for bariatric surgeons and physicians alike to be familiar. Our objectives were to review the appropriate evaluation and treatment options for etiologies of hypoglycemia after gastric bypass and to create an algorithm that biochemically assesses the etiology of hypoglycemia. The setting was a university hospital in the United States. METHODS: We present the cases of 3 patients who developed symptomatic hypoglycemia from distinct etiologies after laparoscopic Roux-en-Y gastric bypass. We also reviewed the current data regarding diagnosis and treatment. RESULTS: Each patient's evaluation and management is elaborated in detail. We propose a novel algorithm for the biochemical evaluation of hypoglycemia after gastric bypass according to our experience and the review of the literature. CONCLUSION: Most cases of symptomatic hypoglycemia that develop in gastric bypass patients are associated with dietary indiscretions. However, a small subset of patients can develop refractory, recurrent, hyperinsulinemic hypoglycemia from factitious insulin administration or nesidioblastosis.

Elective inguinal hernia repair during Operation Iraqi Freedom.

OBJECTIVE: While there have been many publications regarding trauma care in the deployed environment, there is little discussion on the management of the more mundane maladies. This article examines the role of elective surgical intervention for inguinal hernia repairs within theater. Current U.S. policy transports service members out of theater for elective repair and convalescence. In these times of limited man power, this can represent a significant loss of the fighting strength. METHODS: Between January 2006 and July 2006, military surgeons at the 47th Combat Support Hospital in Iraq repaired 11 inguinal hernias. All patients were encouraged to resume normal duty and physical training as soon as possible. A post-procedure questionnaire was completed 6-12 months after surgery. RESULTS: Four repairs were completed with the Prolene Hernia System (PHS; Ethicon, West Somerville, NJ) and seven repairs using the plug and patch method (C. R. Bard, Inc., Murray Hill, NJ). Ten patients were available for follow-up. There were no wound infections, nerve injuries, or recurrences. Patients returned to full duty within 3 days to 6 weeks. CONCLUSIONS: Based on our experience and the feedback from our patients, no complications were noted in this small population of elective hernia repairs. Further prospective trials with long term follow-up are needed to confirm these initial findings.
