Translation and validation of a Swedish version of the BODY-Q: a patient-reported outcome instrument for weight loss and body contouring surgery.

BODY-Q is self-administered questionnaire that evaluates appearance, function and symptoms related to bariatric- and body contouring surgery. The purpose of this article was to describe the translation process of a Swedish version of BODY-Q and to evaluate its criterion validity to the Swedish questionnaire Sahlgrenska Excess Skin Questionnaire, SESQ. MATERIALS AND METHODS: BODY-Q was translated according to International Society for Pharmacoeconomics and Outcome Research's guidelines. The test of validity was made between parts which were comparable to SESQ. Both questionnaires were responded by 30 subjects who were suffering from excess skin after massive weight loss following bariatric surgery or dieting. RESULTS: The correlation between the two questionnaires varied. The parts of BODY-Q evaluating excess skin on the whole body and parts of the body had higher correlations (rs 0.328-0.766) than the parts evaluating side effects of excess skin and body-image (rs 0.103-0.574). CONCLUSION: The Swedish version of BODY-Q has a good criterion validity and can be recommended in the healthcare for patients with excess skin after massive weight loss and for evaluation of the outcomes from reconstructive surgical procedures.

Depressive symptoms before and after abdominoplasty among post-bariatric patients - a cohort study.

The majority of post-bariatric patients suffer from excess skin after weight loss, impairing physical, psychosocial and mental health. The abdomen is the most common location for excess skin, and abdominoplasty is the most commonly required reconstructive procedure. Abdominoplasty removes excess abdominal skin and attenuates related symptoms, but knowledge regarding mental health-related effects is scarce. Here, we aimed to evaluate the symptoms and severity of depression before and after abdominoplasty in post-bariatric patients and to analyse the relationships between depressive symptoms, quality of life (QoL) and experience of excess skin. We enrolled 110 former obese patients undergoing abdominoplasty. Three questionnaires evaluating the symptoms of depression (Beck Depression Inventory (BDI-II)), experience of excess skin (Sahlgrenska Excess Skin Questionnaire (SESQ)) and QoL (36-item Short-Form Health Survey (SF-36)) were completed preoperatively and 1 year postoperatively. After abdominoplasty, symptoms of depression (BDI sum score) significantly decreased (5.8 vs. 3.0, p = .037). Scores on three BDI questions improved (p < .05), and the SESQ score normalised (p < .001), while the SF-36 score was unaffected. The BDI sum score was moderately correlated with the SF-36 mental composite score (preoperatively, rs = -0.69; postoperatively, rs = -0.66) and fairly correlated with the SF-36 physical composite score (rs = 0.32, rs = 0.26). The correlation between the BDI sum and SESQ scores was poor preoperatively (rs = -0.106) and fair postoperatively (rs = 0.232). The results indicate that abdominoplasty may reduce symptoms of depression in post-bariatric patients. However, the procedure did not affect SF-36 scores. Further studies are required to validate these results.

Lipoxins reduce obesity-induced adipose tissue inflammation in 3D-cultured human adipocytes and explant cultures.

Adipose tissue inflammation drives obesity-related cardiometabolic diseases. Enhancing endogenous resolution mechanisms through administration of lipoxin A4, a specialized pro-resolving lipid mediator, was shown to reduce adipose inflammation and subsequently protects against obesity-induced systemic disease in mice. Here, we demonstrate that lipoxins reduce inflammation in 3D-cultured human adipocytes and adipose tissue explants from obese patients. Approximately 50% of patients responded particularly well to lipoxins by reducing inflammatory cytokines and promoting an anti-inflammatory M2 macrophage phenotype. Responding patients were characterized by elevated systemic levels of C-reactive protein, which causes inflammation in cultured human adipocytes. Responders appeared more prone to producing anti-inflammatory oxylipins and displayed elevated prostaglandin D2 levels, which has been interlinked with transcription of lipoxin-generating enzymes. Using explant cultures, this study provides the first proof-of-concept evidence supporting the therapeutic potential of lipoxins in reducing human adipose tissue inflammation. Our data further indicate that lipoxin treatment may require a tailored personalized-medicine approach.

Aspects of excess skin in obesity, after weight loss, after body contouring surgery and in a reference population.

BACKGROUND: Excess skin is well known after massive weight loss but, there is missing knowledge from various groups. OBJECTIVES: To describe and compare excess skin in a reference population during obesity, after obesity surgery, and after reconstructive abdominoplasty. SETTING: University hospital, Sweden. METHODS: The following 6 groups were included: the reference population, obese adults before obesity surgery, obese adults after obesity surgery, adolescents after obesity surgery, super-obese adults after obesity surgery, and adults after abdominoplasty. All groups filled in the Sahlgrenska Excess Skin Questionnaire (SESQ). Some groups also underwent measurements of ptosis/excess skin on 4 body parts. RESULTS: All groups scored significantly higher experience of and discomfort from excess skin compared with the reference population. SESQ scores were significantly higher for obese adults (10.5 ± 8.5) and even higher for adults and adolescents (12.3 ± 8.1 versus 14.4 ± 7.7) after obesity surgery compared with the reference population (1.5 ± 3.5). Abdominoplasty resulted in significantly reduced scores (2.9 ± 5.2). Those undergoing obesity surgery and weight loss had significantly less excess skin measured on arms, breasts, and abdomen compared with before surgery, except for the upper arms on the adolescents. Excess skin increased on inner thighs in both age groups after weight loss. Correlations between objectively measured ptosis/excess skin and the patients' experience of and discomfort were .16 to .71, and the highest correlations were found among adolescents. CONCLUSION: Excess skin is not a problem for the vast majority of the normal population but is linked to obesity and massive weight loss. The SESQ score illustrates major problems related to excess skin both for obese adults and after obesity surgery for adults and for adolescents, who have problems similar to or worse than adults. Abdominoplasty markedly decreases symptoms.

Evaluation of excess skin in Swedish adults 18-59 years of age.

BACKGROUND: Little is known about excess skin in the normal population. The aim of this study was, therefore, to analyse the prevalence, impairments, and discomfort of excess skin in a cross-section of the Swedish population. METHODS: From the population registry of the Swedish Tax Agency, 1408 subjects living in Västra Götaland County from 18-59 years of age were randomly selected with an equal distribution of the sexes. Additionally, age was equally distributed, although twice as many subjects under 40 years of age were sent the questionnaire due to an expected low response rate for younger people. All subjects were asked to fill out the Sahlgrenska Excess Skin Questionnaire (SESQ), which included questions concerning the amount of and discomfort due to excess skin. RESULTS: No excess skin was reported by 78% of responders, including 71% of women and 87% of men. The responders who reported any excess skin were significantly older, had a higher body mass index (BMI) and reported larger differences between their maximum and current BMI. The most common reported site of excess skin was the abdomen in both women and men (26% and 8%, respectively), and this was reported to cause the most discomfort (median 4 and 2, respectively, on a scale from 0-10). Women graded psychosocial symptoms significantly higher than men, but there were no significant differences in other symptoms. CONCLUSIONS: The results indicate that Swedish adults, regardless of sex, do not suffer from excess skin and may be considered as reference values.

Abdominal plasty with and without plication-effects on trunk muscles, lung function, and self-rated physical function.

BACKGROUND: Weight loss after obesity and pregnancy is associated with excess abdominal skin and weakness of the abdominal wall, which is assumed to cause low back pain and reduce lung function. Today, abdominoplasty is the only known method to treat excess skin, and plication is used to improve aesthetics and function alone or in addition to surgery. There is lack of evidence concerning the surgery's effect on trunk muscles, lung function, and physical function. The aim was to evaluate the effect on trunk muscle endurance, lung function and self-rated physical function after abdominoplasty with and without muscle plication. AIM: To evaluate the effect on trunk muscle endurance, lung function, and self-rated physical function after abdominoplasty with and without muscle plication. METHODS: A series of 125 people were randomised to abdominoplasty with or without rectus abdominis muscle plication. Trunk muscle endurance, lung function, and self-rated physical function (disability rating index) were measured before and 1 year after surgery. RESULTS: There were no significant differences in any of the measured variables between the groups either before or after surgery. A significant decrease (p = .02) in back muscle endurance was seen after abdominoplasty without muscle plication. A significant positive effect (p = .04) in one of the activities (running) assessed by DRI was reported after abdominoplasty with muscle plication. CONCLUSIONS: No significant differences in trunk muscle endurance, lung function, or self-rated physical function were found after abdominoplasty with vs without plication. As the primary indication for surgery was excess skin and not diastasis of the rectus abdominis muscles, there is a need for future trials before conclusions can be drawn of effect of abdominoplasty and plication.

Understanding excess skin in postbariatric patients: objective measurements and subjective experiences.

BACKGROUND: Excess skin is a well-known side effect of massive weight loss after bariatric surgery. However, there is a lack of longitudinal follow-ups. OBJECTIVES: The primary aims of this study were to investigate the development and amount of excess skin after laparoscopic Roux-en-Y gastric bypass and to relate objective results to subjective experiences. SETTING: University hospital. METHODS: From 2009 to 2012, 200 patients were included and assessed with respect to excess skin before and 18 months after bariatric surgery. Patients were measured according to a standardized protocol and completed a questionnaire regarding their subjective experience of excess skin. RESULTS: A follow-up visit was completed in 149 patients (78%). All ptosis measurements decreased after weight reduction except for ptosis on the thighs. When comparing objective measurements with patients' subjective experience and discomfort from excess skin, we found little or low correlation in most body parts (rs .03-.67). The prediction analysis indicated that, for every centimeter of ptosis on the abdomen preoperatively, there was a 2-fold greater probability of having a postoperative ptosis on the abdomen of>3 cm (OR = 2.32, 1.76-3.07). CONCLUSION: The objective measurement of excess skin provides unique information in postbariatric patients' body habitus. Although the measured excess skin decreased compared with preoperative measurements, patients seem to become more aware of and disturbed and discomforted by it after the weight loss. Importantly, the objectively assessed measurements of excess skin correlated fairly with the perceived discomfort.

The Effect of Abdominoplasty and Outcome of Rectus Fascia Plication on Health-Related Quality of Life in Post-Bariatric Surgery Patients.

BACKGROUND: The authors prospectively evaluated the effect of isolated abdominoplasty with or without rectus fascia plication on the physical, functional, and psychosocial dimensions of health-related quality of life in post-bariatric surgery patients. They also evaluated whether the objectively measured amount of abdominal excess skin affects the discomfort of excess abdominal skin and changes in health-related quality of life after abdominoplasty. METHODS: Ninety-four post-bariatric surgery patients answered questionnaires regarding their experience of excess skin and health-related quality of life before and 1 year after isolated abdominoplasty. An objective assessment of the amount of abdominal excess skin was also performed. All study participants were assigned randomly to either undergo or not undergo rectus fascia plication. RESULTS: Significant improvements were reported at the follow-up concerning physical, functional, and psychosocial dimensions of health-related quality of life. A significant decrease was observed for the general health subscale of the 36-Item Short-Form Health Survey for the nonplicated group (p = 0.039). No significant differences were observed between the plicated and nonplicated groups. A significant low correlation was identified between the change in the Short-Form physical function subscale after abdominoplasty and measured amount of excess abdominal skin (rs = 0.26, p = 0.033) or resection weight (rs = 0.20, p = 0.10). CONCLUSIONS: Isolated abdominoplasty in post-bariatric surgery patients seems to improve both physical and psychosocial dimensions of health-related quality of life. However, rectus fascia plication does not appear to influence health-related quality of life. In addition, the correlation between the objectively measured amount of abdominal excess skin and improvements in health-related quality of life after abdominoplasty in post-bariatric surgery patients appears to be low.

Development of excess skin and request for body-contouring surgery in postbariatric adolescents.

BACKGROUND: Little is known about the development of excess skin and requests for body-contouring surgery after bariatric surgery in adolescents. METHODS: Forty-seven of 86 adolescents that had undergone gastric bypass surgery answered two questionnaires regarding excess skin and requests for and performed body-contouring surgery. An objective assessment of the amount of excess skin was also performed. The results were compared to earlier results from postbariatric adults. RESULTS: The most common overall problem in adolescents was the feeling of having an unattractive body (91 percent). The most common locations for developing excess skin were the upper arms and thighs according to the measurements. Five of 47 adolescents had undergone body-contouring surgery, and 88 percent of the others desired one or more body-contouring operations. Correlations were found between the objectively measured excess skin and the subjectively experienced amount of excess skin. Correlations were also found between the measured excess skin and the experienced discomfort of excess skin for the abdomen, breast/chest, upper arms, and chin. CONCLUSIONS: The authors' results indicate that bariatric surgery in adolescents often leads to severe problems associated with excess skin in both sexes. Thus, the commonly held belief that young people do not develop excess skin to the same extent as adults is strongly questioned. Health care professionals must address the current imbalance between requests for and the performance of body-contouring surgery in adolescents. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Sahlgrenska Excess Skin Questionnaire (SESQ): a reliable questionnaire to assess the experience of excessive skin after weight loss.

There is a lack of knowledge and reliable measurement instruments to assess excess skin after massive weight loss. The purpose of this study was to test the reliability of a new self-administered questionnaire. A self-administered questionnaire, the Sahlgrenska Excess Skin Questionnaire (SESQ) was designed to assess excess skin after weight loss. The questionnaire includes 30 questions about demographic data, activity and daily life and excess skin on specific body parts and the body as a whole. Forward and backward translations were made by two independent professional translators, from Swedish to English and then back to Swedish. The questionnaire was tested on 10 patients from Sweden and England and was followed by an interview with each patient. Minor corrections were made. A test-retest was carried out to evaluate the reliability by sending the Swedish questionnaire to 46 subjects with weight loss after obesity surgery, dieting, or medication. The test-retest reliability of questions concerning activity and daily life between the two occasions had a Percentage Of Agreement (POA) of 49%-76% and a weighted Kappa of 0.44-0.78. The questions about the degree of excess skin on specific body parts had a POA of 50%-76% and a weighted Kappa of 0.53-0.81. Excess skin perceived as causing problems had a POA of 32%-57 %, an adjusted POA of 63%-87%, and an Intra-Class Correlation of 0.72-0.92. The SESQ is reliable for evaluating patients' experience of excess skin after massive weight loss.

Complications of abdominoplasty after weight loss as a result of bariatric surgery or dieting/postpregnancy.

It is well known that the risk of complications after abdominal contouring surgery is high. Sparse data in published reports exist, suggesting that complication rates are higher in postbariatric patients compared with patients who have lost weight by dieting. The aim of this study was to analyse the incidence of complications after abdominoplasty in postbariatric patients compared with in patients who have not had weight loss surgery. The aim was also to identify predictive factors associated with the development of postoperative complications. This study retrospectively analysed 190 consecutive patients operated on with abdominoplasty due to abdominal tissue excess from January 2006 to December 2008 at Sahlgrenska University Hospital. Variables analysed were sex, age, max body mass index (BMI), delta BMI (max BMI minus preoperative BMI), preoperative BMI, method of weight reduction, resection weight, and complications. The early complication rates were significantly higher in postbariatric patients (48%) than in patients who had not had weight loss surgery (29%). Resection weight was significantly higher for patients with early local complications compared with patients without early local complications. Max BMI, delta BMI, or preoperative BMI had no influence on the incidence of complications. In conclusion, this study confirms in a fairly large sample that the complication rate after abdominoplasty seems to be higher in postbariatric patients compared with patients who have not had weight loss surgery. However, no predictive factors could be identified explaining these differences. Further studies need to be conducted to identify predictive factors for the occurrence of complications after abdominal contouring surgery.

A systematic review of outcomes of abdominoplasty.

Abdominoplasty is a well-established operation to remove abdominal tissue excess. The patients' benefits and risks of this surgical treatment are, however, incompletely studied. The aim of this study was to evaluate the quality of evidence of benefits and risks for patients having abdominoplasty from massive weight loss or childbirth. Outcome measures were quality-of-life, respiratory function, back pain, and complication rates. PubMed, Cochrane Database of Systematic Reviews, CRD, CINDAHL, AMED, PsycInfo and different Health technology Assessment organizations (SBU, Kunnskapssenteret, Sundhetsstyrelsen) were searched for articles published until October 2011. Inclusion criteria were studies written in English or Scandinavian language including at least 30 patients with a control group and a case series of at least 100 patients. Review articles and case studies were excluded. The scientific level of evidence was evaluated using the GRADE-system. One small controlled study on abdominoplasty was found indicating a positive effect on quality-of-life. No controlled studies evaluating the other outcomes respiratory function and back pain were found. One prospective study reported minor complications averaging to 25%. Fourteen retrospective studies reported the same pattern. The major complication venous thromboembolism was found in 2%-8% in three series. It is concluded that the quality of evidence of positive health effects for patients having abdominoplasty is very low concerning all studied outcomes.
