Abstract
BACKGROUND/AIMS Roux-en-Y gastric bypass surgery is the most common bariatric surgery worldwide. We have described thiamine deficiency in patients with small intestinal bacterial overgrowth after gastric bypass. We hypothesized that symptoms of thiamine deficiency are common after gastric bypass. The aims of this study were to examine the prevalence of and treatment of symptoms of thiamine deficiency after gastric bypass. METHODS This is a prospective study performed in a large urban, community hospital. Consecutive gastric bypass patients seen from February 1, 2008 to May 1, 2009 are included. Thiamine deficiency in this study included both: consistent clinical symptoms and either (1) low blood thiamine level or (2) resolution of clinical symptoms after receiving thiamine. RESULTS Of 151 patients, 25 females and 2 males met the criteria for thiamine deficiency (prevalence of 18%). In these 27 patients, 12 had one symptom of thiamine deficiency, while 15 had symptoms consistent with multiple subtypes. Eleven patients reported constipation at 0.33-12 years (mean 4.8) after gastric bypass. Elevated serum folate levels were seen in 6 of 10 tested patients and there was an abnormal glucose-hydrogen breath test in 9 of 10 tested patients, supporting the presence of small intestinal bacterial overgrowth. Frequency of defecation improved after thiamine treatment. CONCLUSION Thiamine deficiency resulting from small intestinal bacterial overgrowth should be considered in patients being seen for constipation after gastric bypass surgery.

Abstract
Lifestyle intervention programmes often produce insufficient weight loss and poor weight loss maintenance. As a result, an increasing number of patients with obesity and related comorbidities undergo bariatric surgery, which includes approaches such as the adjustable gastric band or the 'divided' Roux-en-Y gastric bypass (RYGB). This Review summarizes the current knowledge on nutrient deficiencies that can develop after bariatric surgery and highlights follow-up and treatment options for bariatric surgery patients who develop a micronutrient deficiency. The major macronutrient deficiency after bariatric surgery is protein malnutrition. Deficiencies in micronutrients, which include trace elements, essential minerals, and water-soluble and fat-soluble vitamins, are common before bariatric surgery and often persist postoperatively, despite universal recommendations on multivitamin and mineral supplements. Other disorders, including small intestinal bacterial overgrowth, can promote micronutrient deficiencies, especially in patients with diabetes mellitus. Recognition of the clinical presentations of micronutrient deficiencies is important, both to enable early intervention and to minimize long-term adverse effects. A major clinical concern is the relationship between vitamin D deficiency and the development of metabolic bone diseases, such as osteoporosis or osteomalacia; metabolic bone diseases may explain the increased risk of hip fracture in patients after RYGB. Further studies are required to determine the optimal levels of nutrient supplementation and whether postoperative laboratory monitoring effectively detects nutrient deficiencies. In the absence of such data, clinicians should inquire about and treat symptoms that suggest nutrient deficiencies.

Abstract
Roux-en-Y gastric bypass surgery remains the major surgical option for individuals with medically complicated obesity. The importance of preoperative evaluation to permit identification of micronutrient deficiencies is being re-evaluated. The risk of complications related to pregnancy after gastric bypass supports careful follow-up. Micronutrient deficiencies are common in postoperative gastric bypass patients, despite the suggested use of routine vitamin and mineral supplements after surgery. Copper deficiency must be considered as an origin for visual disorders after gastric bypass. Vitamin D deficiency with metabolic bone disease remains common after gastric bypass and the results suggest that the present postoperative supplements of calcium and vitamin D are inadequate. Major nutritional complications of bariatric surgery are occurring more than 20 years after surgery. There is no evidence for intestinal adaptation as there remains decreased intestinal absorption of iron up to 18 months after gastric bypass surgery. This article supports ongoing examination of nutritional complications after gastric bypass surgery and supports the notion that the daily doses of micronutrient supplements, such as vitamin D, may need to be revised.

Abstract
The National Longitudinal Study of Adolescent Health and the National Health and Nutrition Examination Survey reported that over 40% of the US population is overweight. The average weight loss attained by medical management programs is neither sufficient nor durable enough to treat medically complicated obesity. An estimated 220,000 bariatric procedures are performed yearly in the USA and Canada. The divided Roux-en-Y gastric bypass (RYGB) is performed most commonly in these countries and is considered the gold standard bariatric surgical procedure. The complexity of RYGB means that serious and potentially preventable perioperative complications can occur. RYGB alters the normal anatomy and physiology of the upper gut, which has predictable adverse effects and potential complications. Patients seek advice and care for symptoms that develop or persist after RYGB; although some symptoms are expected and predictable, others are complications that may or may not require active medical or surgical intervention. Physicians should be able to predict and manage most postoperative medical and nutritional disorders related to RYGB and should be prepared to assess patients for potential referral for surgical intervention or revision.

Abstract
Bariatric surgery has become an increasingly important method for management of medically complicated obesity. In patients who have undergone bariatric surgery, up to 87% with type 2 diabetes mellitus develop improvement or resolution of their disease postoperatively. Bariatric surgery can reduce the number of absorbed calories through performance of either a restrictive or a malabsorptive procedure. Patients who have undergone bariatric surgery require indefinite, regular follow-up care by physicians who need to follow laboratory parameters of macronutrient as well as micronutrient malnutrition. Physicians who care for patients after bariatric surgery need to be familiar with common postoperative syndromes that result from specific nutrient deficiencies.

Abstract
BACKGROUND In the morbidly obese patient undergoing laparoscopic gastric bypass (LGBP), insufflation with carbon dioxide to 20 mmHg for prolonged periods may induce significant hypercarbia and acidosis with attendant sequelae. We hypothesize that the use of helium as an insufflating agent results in less hypercarbia and acidosis. METHODS The study was performed between May and November 2002. A Paratrend 7 fiberoptic probe was placed via a carotid artery catheter in 5 adult Yorkshire swine as continuous pH and pCO2 levels were measured. Animals were ventilated to a constant pCO2, after which LGBP was performed. Blood gas values were measured during the procedure and for 1 hour after release of pneumoperitoneum. Helium was used for insufflation in 3 of the pigs and CO2 in 2. Comparison of arterial pH and pCO2 were made between groups. RESULTS Mean maximum pCO2 for the control group (CO2 insufflation) was 99.75 +/- 22.98 mmHg, while for the experimental group (helium insufflation) was 52.86 +/- 6.27 mmHg (P=.036). Mean low pH for the groups were 7.10 +/-.056 and 7.36 +/-.015 (P =.004) respectively. Normalization of pCO2 in the helium group occurred at a mean of 14.58 min (SD 13.3 min) after release of pneumoperitoneum, while in the control group levels did not normalize (mean final pCO2= 71.5 mmHg). CONCLUSIONS Helium pneumoperitoneum in LGBP is associated with less intraoperative hypercarbia and acidosis than is the use of CO2. In addition, pCO2 returns to normal more rapidly postoperatively with the use of helium insufflation. Study of helium insufflation in humans undergoing LGBP is needed to prove its benefits in the clinical setting.

Abstract
OBJECTIVE Rising costs and lowered reimbursements make value essential if laparoscopic cholecystectomy (LC) is to be offered to patients without condemning providers to financial loss. We hypothesize that our protocol increases this value. Once practiced, operative time, complications, and patient satisfaction compare with those of the typical method. METHODS We prospectively randomized 50 consecutive patients equally to control or experimental LC according to our protocol. Equipment costs, operative time, conversions, complications, pain, and return to work were compared. The student's t test was used for comparisons. RESULTS Mean disposable equipment costs were 173.00 dollars +/- 43.45 dollars and 434.42 dollars +/- 50.54 dollars for the study and control groups, respectively (P < .0001). Mean operative times were 67.26 +/- 15 and 70.60 +/- 19 minutes, respectively. CONCLUSIONS The "bare bones" protocol is safe. It has a short learning curve, demonstrates a cost advantage over the common method, and requires no additional operative time. Pain, time to return to work, and satisfaction are equivalent.

Abstract
BACKGROUND There is controversy whether laparoscopic donor nephrectomy (LDN) is the procedure of choice for live kidney donors. The purpose of this survey therefore was to determine the current practices, attitudes, and plans regarding LDN in high-volume renal transplant centers. METHODS Medical directors of the 31 highest volume kidney transplant centers were surveyed via telephone. Kidney transplant data for 1998 and 1999 were collected. RESULTS The surveyed centers performed 5213 transplantations in 1998, representing 43% of all kidney transplantations done nationally. Twelve (39%) of the 31 centers performed LDN in 1998, increasing to 20 (65%) of 31 in 1999. Of 1174 live donor operations performed by the 20 centers in 1999, 365 (31%) were LDNs. Among the surveyed centers, four had no plans to begin an LDN program. The most commonly cited incentive for LDN was "shorter recovery time," whereas the most common disincentive was "concern about graft quality." A combination of observation and animate laboratory was the most commonly reported method of learning the LDN procedure. Six-month follow-up interviews found that 26 (84%) of 31 centers had performed LDN; only 1 of the 31 centers had no plans to perform LDNs. CONCLUSIONS LDN may be the de facto procedure of choice for live donors within the next year. Efforts should now focus on improving techniques for performing and teaching this procedure.

Abstract
This study analyzed age as a univariate factor in survival in a national group of 46,613 major trauma patients and compared 180 elderly major trauma patients (greater than or equal to 65 years) to a similarly injured group of 3,918 younger patients (less than 65 years). In the national group, mortality rose sharply between age 45 (10%) and 55 (15%) and doubled at age 75 years (20%). This age-dependent survival decrement occurred at all Injury Severity Score values, for all mechanisms of injury, and for all body regions. In the comparison study, mortality in the elderly group was nearly double that of mortality in the younger group (27% vs. 14%). The older patients had a markedly higher complication death rate, especially for pulmonary (14/100 vs. 6.1/1100) and infectious complications (4.6/100 vs. 0.7/100). The median length of stay was twice as long for the older patients (14 days vs. 7 days). Cost data showed that the DRG prospective payment system grossly underestimated the cost of care for these patients (mean loss of $2,177.14 per patient). To minimize mortality and morbidity, triaging elderly trauma victims to trauma centers at a much lower threshold than similarly injured younger patients is recommended. The current DRG system should be altered to account for age-dependent morbidity. Further study is needed to determine whether more rigorous infection prophylaxis, immunomodulation, and pulmonary therapy will augment survival in elderly patients.
