The Outcome of Bariatric Surgery in Patients Aged 75 years and Older

Background

Bariatric surgery has been shown to be safe and effective in patients aged 60–75 years; however, outcomes in patients aged 75 or older are undocumented.

Methods

Patients aged 75 years and older who underwent bariatric procedures in two academic centers between 2006 and 2015 were studied.

Results

A total of 19 patients aged 75 years and above were identified. Eleven (58%) were male, the median age was 76 years old (range 75–81), and the median preoperative body mass index (BMI) was 41.4 kg/m² (range 35.8–57.5). All of the bariatric procedures were primary procedures and performed laparoscopically: sleeve gastrectomy (SG) (n?=?11, 58%), adjustable gastric band (AGB) (n?=?4, 21%), Roux-en-Y gastric bypass (RYGB) (n?=?2, 11%), banded gastric plication (n?=?1, 5%), and gastric plication (n?=?1, 5%). The median operative time was 120 min (range 75–240), and the median length of stay was 2 days (range 1–7). Three patients (16%) developed postoperative atrial fibrillation which completely resolved at discharge. At 1 year, the median percentage of total weight loss (%TWL) was 18.4% (range 7.4–22.0). The 1-year %TWL varied among the bariatric procedures performed: SG (21%), RYGB (22%), AGB (7%), and gastric plication (8%). There were no 30-day readmissions, reoperations, or mortalities.

Conclusion

Our experience suggests that bariatric surgery in selected patients aged 75 years and older would be safe and effective despite being higher risk. Age alone should not be the limiting factor for selecting patients for bariatric surgery.

     

Laparoscopic Roux-en-Y Gastric Bypass in Morbidly Obese Patients ≥55 Years Old

Background Advanced age is considered a relative contraindication to bariatric surgery at some institutions because of concerns about higher morbidity and less than optimal weight loss. The aim of our study was to evaluate the operative outcomes, length of stay, weight loss, and improvement of comorbidities in patients ≥55 years old who underwent laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery in our institution. Methods Retrospective data on 33 patients (26 women and 7 men) ≥55 years of age who underwent LRYGB from January 2003 to December 2006 were reviewed. Results Average patient age was 59 years (range 55–68 years), and the mean preoperative body mass index was 47 kg/m² (range 41.1–55.8 kg/m²). The median length of hospital stay was 3 days. There were no intraoperative or postoperative deaths. Early complications were one anastomotic leak, two upper gastrointestinal bleedings, and two readmissions for intractable vomiting. Late complications included four anastomotic strictures and one small bowel obstruction. Patients were followed for a mean 13 months (range 3–24 months). The mean excess body weight (EBW) loss was 13.5 kg (23%), 23.3 kg (39.8%), 33.3 kg (58.1%), 39.8 kg (66.8%), 40.1 kg (69.5%), and 40.8 kg (75.3%) at 1, 3, 6, 9, 12 and 24 months, respectively. Diabetes mellitus improved in 19 (100%) patients and completely resolved in 10 (53%). Hypertension improved in 18 (64%) patients, completely resolved in 9 (32%) and was unchanged in 10 (36%). Conclusions LRYGB is safe and effective in morbidly obese patients ≥55 years of age.     

Results of Laparoscopic Gastric Bypass in Patients ≥55 Years Old

Background: Laparoscopic Roux-en-Y gastric bypass (LRYGBP) is a commonly performed surgical intervention for morbid obesity. Some authors considered age ≥55 years as a relative contraindication to bariatric surgery. We examined the operative outcomes, weight loss, hospital stay and resolution of co-morbidities in patients ≥55 years old compared with those <55 years old undergoing LRYGBP. Methods: From Jan 2000 to Feb 2005, 350 LRYGBPs were performed. 48 patients ≥55 years old (13.7%) were compared to the remaining patients. Results: Analysis of the 48 patients ≥55 years old compared with 302 patients <55 revealed no difference in complication rate, although the older patients had a significantly greater percentage of serious complications. Younger patients lost more weight than older patients. Both groups demonstrated resolution of comorbidities, although the difference was not significant. Conclusions: LRYGBP is safe and well tolerated in morbidly obese patients ≥55 years. The older patients had more serious complications and lost less weight; however, their weight loss and resolution of co-morbidities improved their quality of life. Age should not be a contraindication to bariatric surgery.     

Use of PlasmaJet™ System in Patients Undergoing Abdominal Lipectomy following Massive Weight Loss Resulting from Bariatric Surgery: Early Experience

Background: Abdominoplasty has become a popular operation among patients seeking body contouring surgery due to the recent development of laparoscopic procedures in bariatric surgery and the epidemic diffusion of obesity. The wide surface of dissection is responsible for common postoperative complications such as seroma and hematoma. Methods: PlasmaJet^™ system (PJS), a high energy flow of ionized gas, can be used to stop capillary bleeding from blood and lymph vessels. We tested the PJS in a prospective series of 15 consecutive patients undergoing abdominoplasty after bariatric surgery-induced weight loss. Results: 14 women underwent abdominoplasty with the PlasmaJet^™ system after a mean weight loss of 48 kg (range 37-53). Mean operative time was 73 min (range 60-87). There was no postoperative complication. Mean fluid output from drains was 351.1 ml/patient (range 60 to 568), and drains were removed at a mean time of 4.8 days (range 3 to 6). Conclusion: These results are in favor of the efficacy of the PJS in reducing the amount of fluid production, and the rate of postoperative complications. However, this should be confirmed in a randomized trial comparing the PJS with standard technique.     

Bariatric Surgery Outcomes in Patients Aged 65 Years and Older at an American Society for Metabolic and Bariatric Surgery Center of Excellence

Background  

Although morbid obesity rates in patients ≥65 years of age are increasing, few centers have reported weight loss surgery outcomes in elderly patients, resulting in a paucity of literature on perioperative mortality and morbidity.     

Significance of Alpha-Fetoprotein and Des-γ-Carboxy Prothrombin in Patients with Hepatocellular Carcinoma Undergoing Hepatectomy

Background  

Alpha-fetoprotein (AFP) and des-γ-carboxy prothrombin (DCP) are well-known tumor markers of hepatocellular carcinoma (HCC). The aims of this study are to calculate the sensitivity/specificity of AFP and DCP measurement for the diagnosis of HCC, measure response rates of the markers following curative-intent resections, determine the correlations between the marker levels and clinicopathological prognostic variables, and determine the correlations between the marker levels before hepatectomy and those at diagnosis of recurrence.     

Is Neuraxial Anesthesia Safe in Patients Undergoing Surgery for Treatment of Periprosthetic Joint Infection?

BackgroundThere is concern that neuraxial anesthesia in patients undergoing surgery for treatment of a periprosthetic joint infection (PJI) may increase the risk of having a central nervous system infection develop. However, the available data on this topic are limited and contradictory.Questions/purposesWe wished to determine whether neuraxial anesthesia (1) is associated with central nervous system infections in patients undergoing surgery for a PJI, and (2) increases the likelihood of systemic infection in these patients.MethodsAll 539 patients who received neuraxial or general anesthesia during 1499 surgeries for PJI from October 2000 to May 2013 were included in this study; of these, 51% (n = 764) of the surgeries were performed in 134 patients receiving neuraxial anesthesia and 49% were performed in 143 patients receiving general anesthesia. Two hundred sixty-two patients received general and neuraxial anesthesia during different surgeries. We used the International Classification of Diseases, 9^th Revision codes and the medical records to identify patients who had an intraspinal abscess or meningitis develop after surgery for a PJI. Multivariate analysis was used to assess the effect of type of anesthesia (neuraxial versus general) on postoperative complications.ResultsThere were no cases of meningitis, but one epidural abscess developed in a patient after neuraxial anesthesia. This patient underwent six revision surgeries during a 42-day period. Patients who received neuraxial anesthesia had lower odds of systemic infections (4% versus 12%; odds ratio, 0.35; 95% CI, 023–054; p < 0.001).ConclusionsCentral nervous system infections after neuraxial anesthesia in patients with a PJI appear to be exceedingly rare. Based on the findings of this study, it may be time for the anesthesiology community to reevaluate the risk of sepsis as a relative contraindication to the use of neuraxial anesthesia.

Are Coronary Angiograms of Value in the Risk Stratification of Patients Undergoing Coronary Artery Bypass Surgery?

INTRODUCTION

There are currently more than 20 risk-scoring systems that attempt to predict peri-operative mortality following coronary artery bypass surgery (CABG). All these scoring systems use objective criteria to assess operative risk. Angiographic data are currently not included in any of these systems. This pilot study assessed the value of coronary angiography in predicting peri-operative mortality following CABG.

PATIENTS AND METHODS

Fourteen patients who died following first-time isolated CABG surgery were identified. These were matched with 14 patients of similar age, sex, left ventricle function and European System for Cardiac Operative Risk Evaluation (EuroSCORE). A panel of 25 clinicians were given details of the patients'' age, sex, diabetic status, family history, smoking history, hypertensive status, lipid status, pre-operative symptoms, left ventricle ejection fraction and weight and shown the coronary angiograms of the patient. They were asked to predict the outcome following CABG for each patient.

RESULTS

Receiver operator characteristic curves were constructed and the area under the curves calculated and analysed using a commercially available statistical package (PRISM). The area under the curve for the group was 0.6820 for the group. Consultant clinicians achieved an area of 0.6789 versus their trainees 0.6844 (P = NS). The cardiologists achieved an area of 0.7063 versus the cardiothoracic surgeons 0.6491 (P = NS).

CONCLUSIONS

Despite the EuroSCORE predicting equal risk for the two groups of patients, it would appear that clinicians are able to identify individual higher risk patients by assessing pre-operatively the quality of the patient'' coronary vasculature. Although the clinicians were able to predict individual patient mortality better than the EuroSCORE, the area under the curve indicates that it is not a robust method and clinicians, with all the clinical information to hand, are only moderately good at predicting the outcome following coronary artery bypass surgery.     

Significance of radical cystectomy for bladder cancer in patients over 80 years old

Objectives The objective of this study was to evaluate the usefulness of radical cystectomy for bladder cancer in elderly patients. Materials and methods This study included 72 patients aged ≥80 years (group A) who underwent radical cystectomy and urinary diversion between January 1995 and December 2003, and the clinical outcome of these patients were compared with those of 557 patients aged <80 years (group B) undergoing radical cystectomy during the same period as group A. Results As the procedure for urinary diversion, ureterocutaneostomy was most frequently performed in group A (87.5%), while neobladder creation was most common in group B (43.8%). Despite the absence of significant differences in tumor grade and incidence of lymph node metastasis between these two groups, pathological stage in group A was significantly greater than that in group B. The perioperative mortality rate in group A was significantly higher than that in group B, whereas the incidences of both early and late postoperative complications in group A were similar to those in group B. Cancer-specific survival in group A was significantly lower than that in group B; however, among patients with disease ≤pT2, there was no significant difference in cancer-specific survival between these two groups. Conclusions These findings suggest that an aggressive surgical approach may be an optimal therapeutic strategy for properly selected elderly patients who require definitive therapy for locally invasive bladder cancer, particularly in those with disease ≤pT2.     

The Surgical Treatment of Breast Cancer in the Elderly: A Single Institution Comparative Review of 5235 Patients with 1028 Patients ≥70 years

Abstract: As the wave of the baby boomers shifts the age demographic of patients, the current surgical management of breast cancer in elderly women (≥70 years of age) becomes relevant because deviation from standard treatment often occurs in this group. The purpose of this study was to determine the operative mortality when treated with standard surgical procedures and to investigate trends in the surgical management of breast cancer in the elderly. A total of 5,235 patients undergoing either mastectomy or breast conservation surgery (BCS) for invasive and ductal carcinoma in situ (DCIS) were identified in a retrospective review of a prospectively accrued data base between the years of 1994 and 2007 at the Moffitt Cancer Center. Of the 5,235 patients, 1,028 (20%) patients were ≥70 years of age. The 30‐day and 90‐day mortality in the elderly group (age ≥70 years) was 0.2% (95% CI 0.02–0.7%) and 0.7% (95% CI 0.3–1.4%), respectively. The 30‐day and 90‐day mortality among patients <70 years was 0 and 0.05% (2 of 4,207 patients) (95% CI 0.005–0.2), respectively. BCS rates for invasive carcinomas were the highest for patients between 40 and 70 years of age, whereas the mastectomy rates were higher among patients <40 years of age (53%). Elderly women were as likely as women <40 years to have BCS for invasive carcinoma (OR 1.1, 95% CI 0.8–1.5), but more likely to have BCS for DCIS (OR 1.9, 95% CI 1.1–3.3). Surgical mortality in elderly women treated for breast cancer was extremely low and was related to the extent of surgery performed. Breast cancer treatment differed by age groups.     

A Review of 2255 Emergency Abdominal Operations Performed over 17 years (1996–2013) in a Gastrointestinal Surgery Unit in India

There is little information regarding the clinical spectrum and outcome of emergency abdominal operations from specialized units in India. We examined these in our gastrointestinal surgery and liver transplantation unit from a prospective database maintained between July 1996 and April 2013. Out of 9966 operations performed, 2255 (26%) were emergency procedures (reoperations during the same admission, e.g., for necrotizing pancreatitis were excluded). The primary outcome was 30-day postoperative mortality. The mean age of the patients was 47 years (range 1–107) and included the following age groups: 0–18 years (n = 105, 4.7%); 19–64 years (n = 1766, 78.3%), and >65 years (n = 384, 17.0%). The majority were males (1609, 71%), and there were 646 females (29%). The most common indications were small bowel emergencies (598, 26.5%), followed by pancreatic (417, 18.5%) and colonic (281, 12.5%) emergencies. Pancreatic operations were the second commonest in the adult and middle aged group. Colorectal operations were the second commonest in the geriatric age group (>65 years). Emergency operations for other conditions were: postoperative complications following elective operations 171 (7.5%), gastroduodenal bleeding or perforation in 144 (6.3%), and liver surgery in 93 patients (4.1%) patients. In the small bowel emergencies, 223 patients (37.2%) had primary diagnosis of adhesive obstruction, gangrene in 135 patients (22.5%), perforation in 121 patients (20%), and fistula in 56 patients (9.3%). Mesenteric venous thrombosis was found to be the primary cause of small bowel emergencies, either as a primary cause in gangrene or as a secondary cause in perforations and adhesions. The postoperative mortality after emergencies was 12.6% compared to 2% in elective procedures. Mortality was significantly higher in males (14%) than females (9.6%), p < 0.005. Category wise mortality was as follows: pancreatic surgery (n = 86, 20.6%), surgery for postoperative complications (n = 33, 19.3%), duodenal surgery (n = 18, 12.5%), small intestinal surgery (n = 68, 11.4%), and colonic surgery (n = 35, 12.45%). Emergency operations comprise a significant proportion of a GI surgical unit’s workload. The mortality is greatest after pancreatic operations followed by those done for postoperative complications. Despite advances in surgical and postoperative care, emergency operations for abdominal emergencies are associated with mortality which is six times higher compared to elective procedures.     

Obstructive Sleep Apnea in Patients Undergoing Bariatric Surgery—A Tertiary Center Experience

Background  

The patient population that is evaluated for bariatric surgery is characterized by a very high body mass index (BMI). Since obesity is the most important risk factor for obstructive sleep apnea (OSA), sleep disordered breathing is highly prevalent in this population. If undiagnosed before bariatric surgery, untreated OSA can lead to perioperative and postoperative complications. Debate exists whether all patients that are considered for bariatric surgery should undergo polysomnography (PSG) evaluation and screening for OSA as opposed to only those patients with clinical history or examination concerning sleep disordered breathing. We examined the prevalence and severity of OSA in all patients that were considered for bariatric surgery. We hypothesized that, by utilizing preoperative questionnaires (regarding sleepiness and OSA respiratory symptoms) in combination with menopausal status and BMI data, we would be able to predict which subjects did not have sleep apnea without the use of polysomnography. In addition, we hypothesized that we would be able to predict which subjects had severe OSA (apnea–hypopnea index (AHI) > 30).     

Home Return After Surgery in Patients Aged over 85 Years is Associated with Preoperative Albumin Levels,the Type of Surgery,and APACHE II Score

Background

Owing to an aging society, both the number of operations for patients aged >85 years and the average age of patients admitted to the intensive care unit (ICU) are rapidly increasing. However, mortality is not an appropriate outcome measurement in patients aged >85 years; a more important outcome is home return (HR), because quality of life is valuable to these patients. We identified predictors for HR of patients aged >85 years admitted to the ICU after surgery.

Methods

Retrospective analysis of medical records was conducted at a university hospital. Patients aged > 85 years, admitted to the ICU after surgery from March 2006 to June 2015 (n = 187), were divided into a HR group (patients who returned home after discharge) and non-HR group (deceased or transferred to nursing facilities). Perioperative data and outcome were assessed and compared. Multivariate logistic regression analysis was conducted to identify independent predictors.

Results

The average age of patients was 88 years. HR occurred in 61% of patients, and mortality was 9%. The HR group had higher preoperative albumin level than did the non-HR group. More patients in the non-HR group experienced hip surgery than in the HR group (51 vs. 12%, P < 0.001). APACHE II score was higher (P < 0.001) in the non-HR group. In multivariate analysis, preoperative albumin, hip surgery, and APACHE II score were independent predictors of HR.

Conclusion

Predictors of HR of surgical critically ill elderly patients included preoperative albumin level, hip surgery, and APACHE II score on ICU admission.
