Factor structure and measurement invariance of the English- versus Spanish-language Eating Disorder Examination Questionnaire: Brief Form (S-EDE-Q-BF) in Hispanic/Latino/a/x persons seeking bariatric surgery.

BACKGROUND: Assessment of eating disorder psychopathology during preoperative psychological evaluations could be facilitated with psychometrically valid measures. One of the most commonly used measures, the Eating Disorder Examination Questionnaire (EDE-Q), is lengthy and has been found to have psychometric limitations. Research has identified a shorter version that has received reliable support across diverse samples but requires further validation for use with patients being evaluated for bariatric surgery. OBJECTIVES: To cross-validate the factor structure of the EDE-Q: Brief Form (EDE-Q-BF, standalone, nonnested version) with patients being evaluated for bariatric surgery across English- and Spanish-language versions and establish measurement invariance for gender and language. SETTING: Northeastern hospital in the United States. METHODS: Participants (n = 618) undergoing evaluations prior to bariatric surgery who identified as Hispanic/Latino/a/x and consented to participate in this research study (which did not influence eligibility for bariatric surgery) completed self-reports. Of the 618 participants, 92 were male and 526 were female, 318 preferred English and were administered English versions of the measures, and 300 preferred Spanish and were administered Spanish versions of the measures. RESULTS: The 3-factor structure ("Restraint," "Weight/Shape Concerns," and "Body Dissatisfaction") of the EDE-Q-BF fit the data well (χ2 [11] = 18.47; P = .071; root mean square error of approximation [RMSEA] = .033; comparative fit index [CFI] > .99; standardized root mean squared residual [SRMR] = .02). Scaler invariance was met for both gender and language. Correlations with external criteria further supported its validity. CONCLUSION: The EDE-Q-BF can easily be administered as part of a preoperative psychological assessment battery to screen for eating disorder psychopathology and is valid for Hispanic/Latino/a/x men and women who speak either English or Spanish.

Intraoperative leak testing has no correlation with leak after laparoscopic sleeve gastrectomy.

BACKGROUND: Staple line leak is a serious complication of sleeve gastrectomy. Intraoperative methylene blue and air leak tests are routinely used to evaluate for leak; however, the utility of these tests is controversial. We hypothesize that the practice of routine intraoperative leak testing is unnecessary during sleeve gastrectomy. METHODS: A retrospective cohort study was designed using a prospectively collected database of seven bariatric surgeons from two institutions. All patients who underwent sleeve gastrectomy from March 2012 to November 2014 were included. The performance of intraoperative leak testing and the type of test (air or methylene blue) were based on surgeon preference. Data obtained included BMI, demographics, comorbidity, presence of intraoperative leak test, result of test, and type of test. The primary outcome was leak rate between the leak test (LT) and no leak test (NLT) groups. SAS version 9.4 was used for univariate and multivariate analyses. RESULTS: A total of 1550 sleeve gastrectomies were included; most were laparoscopic (99.8%), except for one converted and two open cases. Routine intraoperative leak tests were performed in 1329 (85.7%) cases, while 221 (14.3%) did not have LTs. Of the 1329 cases with LTs, there were no positive intraoperative results. Fifteen (1%) patients developed leaks, with no difference in leak rate between the LT and NLT groups (1 vs. 1%, p = 0.999). After adjusting for baseline differences between the groups with a propensity analysis, the observed lack of association between leak and intraoperative leak test remained. In this cohort, leaks presented at a mean of 17.3 days postoperatively (range 1-67 days). Two patients with staple line leaks underwent repeat intraoperative leak testing at leak presentation, and the tests remained negative. CONCLUSION: Intraoperative leak testing has no correlation with leak due to laparoscopic sleeve gastrectomy and is not predictive of the later development of staple line leak.

Common postoperative findings unique to laparoscopic surgery.

The interpretation of images obtained in patients who have recently undergone abdominal or pelvic surgery is challenging, in part because procedures that were previously performed with open surgical techniques are increasingly being performed with minimally invasive (laparoscopic) techniques. Thus, it is important to be familiar with the normal approach used for laparoscopic surgeries. The authors describe the indications for various laparoscopic surgical procedures (eg, cholecystectomy, appendectomy, hernia repair) as well as normal postoperative findings. For example, port site hernias are more commonly encountered in patients with trocar sites greater than 10 mm and occur at classic entry sites (eg, the periumbilical region). Similarly, preperitoneal air can be encountered postoperatively, often secondary to trocar dislodgement during difficult entry or positioning. In addition, intraperitoneal placement of mesh during commonly performed ventral or incisional hernia repairs typically leads to postoperative seroma formation. Familiarity with normal findings after commonly performed laparoscopic surgical procedures in the abdomen and pelvis allows accurate diagnosis of common complications and avoidance of diagnostic pitfalls.

Gastric banding as a salvage procedure for patients with weight loss failure after Roux-en-Y gastric bypass.

BACKGROUND: This study reviews outcomes after laparoscopic adjustable gastric band (LAGB) placement in patients with weight loss failure after Roux-en-Y gastric bypass (RYGBP). METHODS: All data was prospectively collected and entered into an electronic registry. Characteristics evaluated for this study included pre-operative age and body mass index (BMI), gender, conversion rate, operative (OR) time, length of stay (LOS), percentage excess weight loss (EWL), and postoperative complications. RESULTS: 11 patients (seven females, four males) were referred to our program for weight loss failure after RYGBP (six open, five laparoscopic). Mean age and BMI pre-RYGBP were 39.5 years (24-58 years) and 53.2 kg/m(2) (41.2-71 kg/m(2)), respectively. Mean EWL after RYGBP was 38% (19-49%). All patients were referred to us for persistent morbid obesity due to weight loss failure or weight regain. The average time between RYGBP and LAGB was 5.5 years (1.8-20 years). Mean age and BMI pre-LAGB were 46.1 years (29-61 years) and 43.4 kg/m(2) (36-57 kg/m(2)), respectively. Vanguard (VG) bands were placed laparoscopically in most patients. There was one conversion to open. Mean OR time and LOS were 76 minutes and 29 hours, respectively. The 30-day complication rate was 0% and mortality was 0%. There were no band slips or erosions; however, one patient required reoperation for a flipped port. The average follow-up after LAGB was 13 months (2-32 months) with a mean BMI of 37.1 kg/m(2 )(22.7-54.5 kg/m(2)) and an overall mean EWL of 59% (7-96%). Patients undergoing LAGB after failed RYGBP lost an additional 20.8% EWL (6-58%). CONCLUSION: Our experience shows that LAGB is a safe and effective solution to failed RYGBP.

Objective comparison of complications resulting from laparoscopic bariatric procedures.

BACKGROUND: Several surgical treatment options for morbid obesity exist. Currently, there are no studies that objectively compare complication rates after laparoscopic bariatric operations performed at a single institution. We objectively classify and compare complications resulting from laparoscopic adjustable gastric banding (LABG), Roux-en-Y gastric bypass (RYGB), and biliopancreatic diversion (BPD) with duodenal switch (DS). STUDY DESIGN: A retrospective review of a prospective database of all patients undergoing laparoscopic bariatric operation was performed. Complications were categorized according to severity score using a well-described classification system and compared between procedures. RESULTS: From September 2000 to July 2003, 780 laparoscopic bariatric operations were performed: 480 LAGB, 235 RYGB, and 65 BPD+/-DS. There was one late death. Total complication rates were: 9% for LAGB, 23% for RYGB, and 25% for BPD+/-DS. Complications resulting in organ resection, irreversible deficits, and death (grades III and IV) occurred at rates of 0.2% for LAGB, 2% for RYGB, and 5% for BPD+/-DS. LAGB group had a statistically significant lower overall complication rate, both by incidence and severity, as compared with other groups (p < 0.001). After controlling for differences of admission body mass index, gender, and race, the LAGB group had an almost three and a half times lower likelihood of a complication compared with the RYGB group (odds ratio, 3.4; 95% CI, 2.2-5.3, p < 0.001) and had an over three and a half times lower likelihood of a complication compared with the BPD with DS group (odds ratio, 3.6; 95% CI, 1.8-7.1, p < 0.001). There was no statistically significant difference between complication rates of RYGB and BPD+/-DS. CONCLUSIONS: Bariatric operation complication rates range from 9% to 25%; very few complications are serious. Laparoscopic adjustable gastric banding is the safest operation in terms of complication rate and severity when compared with laparoscopic Roux-en-Y gastric bypass or laparoscopic malabsorptive operations.

Interval gangrene complicating superficial femoral artery stent placement.

Interval gangrene-necrosis of tissue proximal to a successful distal revascularization procedure-is an exceeding rare complication. To date, only nine cases have been reported in the literature, and all were secondary to traditional open bypass procedures. We report the first case, to our knowledge, of interval gangrene after endovascular stent placement in the superficial femoral artery. We believe that with the increasing utilization of endovascular techniques to treat limb ischemia, the serious complication of interval gangrene must be revisited. Assessment of collateral circulation, precise stent placement, and the appropriate choice of stents and stent grafts will become increasing important as more and more of these lesions are treated with endovascular techniques.

Laparoscopic bariatric surgery in super-obese patients (BMI>50) is safe and effective: a review of 332 patients.

BACKGROUND: Bariatric surgery in super-obese patients (BMI >50 kg/m(2)) can be challenging because of difficulties in exposure of visceral fat, retracting the fatty liver, and strong torque applied to instruments, as well as existing co-morbidities. METHODS: A retrospective review of super-obese patients who underwent laparoscopic adjustable gastric banding (LAGB n=192), Roux-en-Y gastric bypass (RYGBP n=97), and biliopancreatic diversion with/without duodenal switch (BPD n= 43), was performed. 30 day peri-operative morbidity and mortality were evaluated to determine relative safety of the 3 operations. RESULTS: From October 2000 through June 2004, 331 super-obese patients underwent laparoscopic bariatric surgery, with mean BMI 55.3 kg/m(2). Patients were aged 42 years (13-72), and 75% were female. When categorized by operation (LAGB, RYGBP, BPD), the mean age, BMI and gender were comparable. 6 patients were converted to open (1.8%). LAGB had a 0.5%, RYGBP 2.1% and BPD 7.0% conversion rate (P=0.02, all groups). Median operative time was 60 min for LAGB, 130 min for RYGBP and 255 min for BPD (P<0.001, all groups). Median length of stay was 24 hours for LAGB, 72 hours for RYGBP, and 96 hours for BPD (P <0.001). Mean %EWL for the LAGB was 35.3+/-12.6, 45.8+/-19.4, and 49.5+/-18.6 with follow-up of 87%, 76% and 72% at 1, 2 and 3 years, respectively. Mean %EWL for the RYGBP was 57.7+/-15.4, 54.7+/-21.2, and 56.8+/-21.1 with follow-up of 76%, 33% and 54% at 1, 2 and 3 years, respectively. Mean %EWL for the BPD was 60.6+/-15.9, 69.4+/-13.0 and 77.4+/-11.9 with follow-up of 79%, 43% and 47% at 1, 2 and 3 years, respectively. The difference in %EWL was significant at all time intervals between the LAGB and BPD (P<0.004). However, there was no significant difference in %EWL between LAGB and RYGBP at 2 and 3 years. Overall perioperative morbidity occurred in 27 patients (8.1%). LAGB had 4.7% morbidity rate, RYGBP 11.3%, and BPD 16.3% (P=0.02, all groups). There were no deaths. CONCLUSION: Laparoscopic bariatric surgery is safe in super-obese patients. LAGB, the least invasive procedure, resulted in the lowest operative times, the lowest conversion rate, the shortest hospital stay and the lowest morbidity in this high-risk cohort of patients. Rates of all parameters studied increased with increasing procedural complexity. However, the difference in %EWL between RYGBP and LAGB at 2 and 3 years was not statistically significant.
