Non-Invasive Ventilation Reduces Postoperative Respiratory Failure in Patients Undergoing Bariatric Surgery: A Retrospective Analysis. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1457. [PMID: 37629747 PMCID: PMC10456476 DOI: 10.3390/medicina59081457] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/08/2023] [Revised: 08/09/2023] [Accepted: 08/10/2023] [Indexed: 08/27/2023]
Abstract
Background and Objectives: Postoperative non-invasive ventilation (NIV) has been proposed as an attractive strategy to reduce morbidity in obese subjects undergoing general anaesthesia. The increased body mass index (BMI) correlates with loss of perioperative functional residual capacity, expiratory reserve volume, and total lung capacity. The aim of the current study is to evaluate the efficacy of NIV in a post-anaesthesia care unit (PACU) in reducing post-extubation acute respiratory failure (ARF) after biliointestinal bypass (BIBP) in obese patients. Materials and Methods: A retrospective analysis was conducted from January 2019 to December 2020 to compare acute respiratory failure within the first 72 postoperative hours and oximetry values of obese patients who underwent BIBP after postoperative NIV adoption or conventional Venturi mask. Results: In total, 50 patients who received NIV postoperative protocol and 57 patients who received conventional Venturi mask ventilation were included in the study. After 120 min in PACU pH, pCO2, pO2, and SpO2 were better in the NIV group vs. control group (p < 0.001). Seventy-two hours postoperatively, one patient (2%) in the NIV group vs. seven patients (12.2%) in the control group developed acute respiratory failure. Therefore, conventional Venturi mask ventilation resulted in being significantly associated (p < 0.05) with postoperative ARF with an RR of 0.51 (IC 0.27-0.96). Conclusions: After bariatric surgery, short-term NIV during PACU observation promotes a more rapid recovery of postoperative lung function and oxygenation in obese patients, reducing the necessity for critical care in the days following surgery. Therefore, as day-case surgery becomes more advocated even for morbid obesity, it might be considered a necessary procedure.

Abstract
BACKGROUND AND AIMS Bariatric surgeries such as gastric banding (LAGB), gastric bypass (RYGB), vertical banded gastroplasty (VBG), and sleeve gastrectomy (LSG) decrease body weight in morbid obesity, leading to the resolution of coexisting diabetes mellitus and arterial hypertension in the majority of cases as well as improvements of renal function and liver steatosis. BS (LAGB, RYGB, VBG, and LSG) also reduce incident cases of diabetes, of cardiovascular diseases, and of cancer; these therapeutic and preventive effects on comorbidities of obesity have not been analyzed for malabsorptive surgeries such as biliopancreatic diversion (BPD) or biliointestinal bypass (BIBP). The aim of this study was to analyze the incidence of comorbidities, i.e., diabetes, cardiovascular diseases, and cancer, in obese subjects undergoing BPD and BIBP, in comparison with standard medical treatment of obesity. PATIENTS AND METHODS Medical records of 1983 obese patients (body mass index (BMI) > 35 kg/m2, aged 18-65 years, undergoing surgery (n = 472, of which 111 with diabetes) or medical treatment (n = 1511, of which 422 with diabetes), during the period 1999-2008 (visit 1)) were collected; incident cases of comorbidities were ascertained through December 31, 2016. RESULTS Observation period was 12.0 ± 3.48 years (mean ± SD). Compared to non-surgical patients matched for age, body mass index, and blood pressure, malabsorptive surgeries were associated with reduced new incident cases of diabetes (p = 0.001), cardiovascular diseases (p = 0.001), hyperlipidemia (p = 0.001), oculopathy (p = 0.021), and cancer (p = 0.001). The preventive effect of BS was similar in both nondiabetic and diabetic patients for cardiovascular diseases and hyperlipidemia (both p = 0.001). The preventive effect was significant in nondiabetic subjects for coronary heart disease and for cancer, not significant in diabetic subjects. CONCLUSION Patients undergoing malabsorptive bariatric surgery show less incident cases of diabetes, cardiovascular diseases, hyperlipidemia, oculopathy, and cancer than controls receiving medical treatment.

Abstract
AIMS Long-term comparisons between bariatric surgical techniques have been performed for gastric bypass (RYGB), sleeve gastrectomy (LSG), and biliopancreatic diversion (BPD) vs gastric banding (LAGB), but short-term studies (6 months-4 years) have only compared biliointestinal bypass (BIBP) and LAGB. The participating institutions regularly perform both BIBP and LAGB with a common protocol, and the aim of this retrospective study was to compare long-term effects of the two procedures on body weight, on clinical and metabolic variables, and on resolution of obesity and of diabetes. METHODS All procedures performed between 01/01/1998 and 31/12/2005 were considered; 73 out of 91 patients undergoing BIBP, and 154 out of 249 patients undergoing LAGB were evaluable up to 9 years. RESULTS BIBP was significantly more effective than LAGB in terms of weight loss and of resolution of obesity (BMI < 30 kg/m2), in terms of decrease of systolic blood pressure and of serum cholesterol, and similar in terms of resolution of diabetes. In addition, the effect of BIBP was stable, while the effect of LAGB decreased with time. CONCLUSIONS Both BIBP and LAGB exert long-term effects on body weight, on blood pressure, and on resolution of diabetes mellitus; the effect of BIBP is significantly greater than the effect of LAGB in terms of weight loss, resolution of obesity, of control of systolic blood pressure and of serum cholesterol, but not in terms of resolution of diabetes.

Long-term mortality in obese subjects undergoing malabsorptive surgery (biliopancreatic diversion and biliointestinal bypass) versus medical treatment. Int J Obes (Lond) 2018; 43:1147-1153. [PMID: 30470806 DOI: 10.1038/s41366-018-0244-5] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/19/2018] [Revised: 07/25/2018] [Accepted: 07/30/2018] [Indexed: 01/06/2023]
Abstract
BACKGROUND AND AIM Aim of this study was to analyze long-term mortality in obese patients receiving malabsorptive bariatric surgery (BS)[biliopancreatic diversion (BPD) and biliointestinal bypass (BIBP)] in comparison to medical treatment of obesity. PATIENTS AND METHODS Medical records of 1877 obese patients [body mass index (BMI) > 35 kg/m2, aged 18-65 years, undergoing BS (n = 472, 111 with diabetes) or non-surgical medical treatment (n = 1405, 385 with diabetes), during the period 1999-2008 (visit 1)] were collected; non-surgical patients were matched for age, sex, BMI, and blood pressure, and life status and causes of death were ascertained through December 2016. Survival was compared across surgery patients and non-surgical patients using Kaplan-Meier plots and Cox regression analyses. RESULTS Observation period was 12.1 ± 3.41 years (mean ± SD). Compared to non-surgical patients, BS patients had reduced all-cause mortality (34/472 (7.2%) vs 181/1,405 (12.9%) patients, χ2 = 11.25, p = 0.001; HR = 0.64, 95% C.I. 0.43-0.93, p = 0.019). Cardiovascular and cancer causes of death were significantly less frequent in surgery vs no-surgery (HR = 0.26, 95% C.I. 0.09-0.72, p = 0.003; HR = 0.21, 95% C.I. 0.09-0.45, p < 0.001, respectively). CONCLUSION Patients who have undergone BPD and BIBP have lower long-term all-cause, cardiovascular-caused and cancer-caused mortality compared to non-surgical medical weight-loss treatment patients. Malabsorptive bariatric surgery significantly reduces long-term mortality in severely obese patients.

Abstract
Background: This study aims to evaluate long-term quality of life (QoL) and primary clinical outcomes, 10 years after biliointestinal bypass (BIB) surgery. It was expected that, although BIB might show encouraging primary outcomes, long term QoL could be significantly impaired. Methods: Ninety patients were contacted for a phone interview [age 41.0 ± 10.6 (mean ± SD) years, age-range 31-65 years]. QoL (by SF-36) and the clinical situation (by ad hoc questionnaire) were collected. Data were analyzed with SPSS 22. SF-36 scores were compared with Italian normative data from general and healthy population. We also compared primary clinical outcomes and SF-36 scores between patients who reported high and low levels of satisfaction with BIB. Results: Considering SF-36 results, patients showed significant impairments in QoL compared to general and healthy populations. Sixty-five percent would repeat the BIB. All patients showed at least one chronic adverse event. It occurred a significant decrease in pre-post co-occurrence rates of diabetes (χ2 = 18.41; p < 0.001) and hypertension (χ2 = 50.27; p < 0.001). Large and significant weight loss indexes (i.e., percent excess weight loss (%EWL); body mass index) were observed between pre-post intervention. Conclusion: BIB showed promising primary clinical outcomes (i.e., hypertension, diabetes, and weight loss). However, subjects reported a significant impairment in all SF-36 domains. Ad hoc psychological interventions should be implemented to ameliorate the quality of life of these patients.

Abstract
BACKGROUND Bilio-intestinal bypass (BIBP) is an uncommon bariatric procedure. In 1999, a prospective trial was started at our institution to evaluate the effectiveness of BIBP. Trial was interrupted in 2006 due to high rate of complications. The aim of the present paper was to retrospectively review 10-year outcomes of BIBP. METHODS Retrospective review of bariatric database was performed to find patients that had undergone BIBP from 1999 to 2006. Data collected were as follows: age, gender, body weight, body mass index (BMI), percentage of excess weight loss (%EWL), remission from weight-related diseases, complications, and deaths at 1,3, 5, 7, and 10 years. Quality of life was evaluated using "BAROS" questionnaire. RESULTS From May 1999 to September 2006, 86 patients underwent BIBP. The mean age was 34.9 ± 22.4 years, and the initial weight and BMI were 141.2 ± 40.4 kg and 49.8 ± 15.5 kg/m2, respectively. After 10 years, the mean %EWL and BMI were 72.6 ± 18.7 and 31.2 ± 5.6 kg/m2. Almost all patients had diarrhea after surgery. Bloating syndrome occurred in 24% of patients, 48% had nephrolithiasis, and 20.9% had cholelithiasis. Remission from diabetes and hypertension was obtained in 75% and 80% of patients. Mortality was 3.2% and reoperation rate was 14.5%. CONCLUSIONS Malabsorption plays a determinant role to obtain a long-lasting treatment for obese patients. However, BIBP is not recommendable due to high rate of complications and metabolic disorders.

Abstract
INTRODUCTION Gallstone ileus is an uncommon disease and accounts for 1-4 % of all cases of mechanical intestinal obstruction. The physiopathology is related to the presence of a bilioenteric fistula. METHOD We report two cases of gallstone ileus in patients operated on biliointestinal bypass for morbid obesity. The anastomosis of the gallbladder to the proximal end of the bypassed jejunum allowed the transit of gallstones in the excluded ileum and its impaction in anti-reflux valvular system. RESULTS Preoperative exams were unable to solve the diagnostic query, and the diagnosis was achieved only at laparotomy. One-stage combined enterolithotomy and cholecystectomy were performed. CONCLUSION The two patients had an uneventful recovery. To our knowledge, this is the first report of gallstone ileus after biliointestinal bypass.

Abstract
OBJECTIVE Malabsorptive bariatric surgery (biliopancreatic diversion and biliointestinal bypass [BIBP]) reduces serum cholesterol levels more than restrictive surgery (adjustable gastric banding [AGB]), and this is thought to be due to greater weight loss. Our aim was to evaluate the changes of cholesterol metabolism induced by malabsorptive and restrictive surgery independent of weight loss. RESEARCH DESIGN AND METHODS In a nonrandomized, self-selected, unblinded, active-comparator, bicenter, 6-month study, glucose metabolism (blood glucose and serum insulin levels and homeostasis model assessment of insulin resistance [HOMA-IR] index) and cholesterol metabolism (absorption: serum campesterol and sitosterol levels; synthesis: serum lathosterol levels; catabolism: rate of appearance and serum concentrations of serum 7-α- and serum 27-OH-cholesterol after infusions of deuterated 7-α- and 27-OH-cholesterol in sequence) were assessed in grade 3 obesity subjects undergoing BIBP (n = 10) and AGB (n = 10). Evaluations were performed before and 6 months after surgery. RESULTS Subjects had similar values at baseline. Weight loss was similar in the two groups of subjects, and blood glucose, insulin levels, HOMA-IR, and triglycerides decreased in a similar way. In contrast, serum cholesterol, LDL cholesterol, non-HDL cholesterol, serum sitosterol, and campesterol levels decreased and lathosterol levels increased only in BIBP subjects, not in AGB subjects. A significant increase in 7-α-OH-cholesterol occurred only with BIBP; serum 27-OH-cholesterol decreased in both groups. CONCLUSIONS Malabsorptive surgery specifically affects cholesterol levels, independent of weight loss and independent of glucose metabolism and insulin resistance. Decreased sterol absorption leads to decreased cholesterol and LDL cholesterol levels, accompanied by enhanced cholesterol synthesis and enhanced cholesterol catabolism. Compared with AGB, BIBP provides greater cholesterol lowering.

Abstract
BACKGROUND Obesity is an increasing health problem and surgery seems to be the only treatment effective in achieving weight loss without relapse. Among bariatric techniques, many differences exist in terms of weight loss and resolution of comorbidities. Up to now, there are no prospective studies comparing long-term effects of malabsorptive vs restrictive techniques. OBJECTIVE In this study, cardiometabolic risk factors and body composition changes after malabsorptive biliointestinal bypass (BIBP) and restrictive laparoscopic adjustable gastric banding (LAGB) were compared during a 4-year follow-up. DESIGN Prospective, case-control and cohort study. PATIENTS In all, 80 obese subjects, matched for weight and age. Altogether, 40 patients underwent BIBP and 40 underwent LAGB. MEASUREMENTS Weight, body composition, fasting and post-loading plasma glucose and insulin, homeostatic model assessment index (HOMA-I), lipid profile, blood pressure (BP), erythrocyte sedimentation rate and fibrinogen were monitored at baseline, 12 and 48 months. RESULTS At 12 months after surgery, a significant reduction in body mass index, total fat mass (FM), trunk FM (trFM), trFM/legs FM (lFM) ratio (trFM/lFM), triglycerides, BP and inflammation markers was observed in both groups. BIBP patients showed a significant reduction in total cholesterol (Tot-C), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C), whereas the LAGB group showed a significant increase of HDL-C. A further improvement of all the parameters evaluated was seen in the BIBP group at 48 months after surgery. CONCLUSIONS Both bariatric procedures exerted positive effects on cardiometabolic risk factors and on weight loss in the population studied, but on the long-term period, HOMA-I, Tot-C/HDL-C ratio and body composition improvements were more evident after BIBP. We conclude that malabsorptive BIBP seems to be more effective than LAGB in treating visceral obesity and its metabolic complications.

Abstract
BACKGROUND AND AIM Bariatric surgery induces significant weight loss and improves glucose metabolism in obese patients (BMI>35 kg/m(2)). Our aim was to compare restrictive (LAGB, laparoscopic gastric banding) and malabsorptive approaches (BIBP, biliary-intestinal bypass) on the loss of fat-free mass (FFM), fat mass (FM), and on changes of glucose and lipid metabolism. METHODS AND RESULTS Body composition (bio-impedance analysis, BIA), blood glucose (BG), insulin, triglycerides, total- and HDL-cholesterol, liver enzymes (AST and ALT) were measured at baseline and 1 year after surgery in patients undergoing LAGB, BIBP, and in diet-treated control patients. In the main study, with patients matched for initial BMI (43-55 kg/m(2), LAGB=24, BIBP=12, controls=6), decreases of BMI, FM, BG and cholesterol were greater in patients with BIBP than with LAGB (p<0.01), while decreases of FFM, insulin, HOMA-IR and triglycerides were similar. No effects on BMI, FM, FFM, BG, insulin, HOMA-IR or cholesterol were observed in the control patients. Decreases of BG, insulin, HOMA-IR, cholesterol and triglycerides correlated with FM but not with FFM decrease. Similar results were obtained in an additional study in patients with a different initial BMI (LAGB=25, BIBP=6, controls=24) and when considering all subjects together. A decrease of liver enzymes (ALT) was greater with LAGB than with BIBP, and HDL-cholesterol increased with LAGB and decreased with BIBP. CONCLUSION BMI, FM, BG and cholesterol decrease more with malabsorptive than with restrictive surgery, while FFM, insulin, HOMA-IR and triglycerides decrease in a similar way. FFM loss is of low entity. Changes of glucose and lipid metabolism are proportional to a decrease of fat mass but not of fat-free mass.

Abstract
BACKGROUND Obese patients are often affected by hypertension, dyslipidaemia, impaired glucose metabolism, and suffer from cardiovascular disease (CVD), related to the characteristic metabolic alterations. AIM OF THE STUDY To evaluate reduction of risk factors for CVDs in morbid-obese patients (body mass index (BMI)>40 kg/m2) after weight loss upon bariatric surgery intervention of biliary-intestinal bypass. SUBJECTS 45 (17 men, 28 women) morbid-obese patients (age: 19-49 y, BMI>40 kg/m2). All patients were selected on the basis of medical history, physical and biochemical evaluation and of psychiatric tests, which were performed on all individuals admitted to our Day Hospital to verify the safety of surgical intervention. MEASUREMENTS Body weight, body composition (by dual X-ray absorptiometry, DXA), blood pressure, lipid profile, fibrinogen and glucose metabolism were monitored at baseline and 1, 3, 6, 9, 12, 24 and 36 months after surgery. RESULTS A significant and persistent weight loss was present in all patients at the end of the 3 y follow-up period (P<0.001), with a progressive reduction of total and trunk fat mass as evaluated by means of DXA. Additionally, a parallel significant reduction in systolic (P<0.001) and diastolic (P<0.001) blood pressure was observed. Total and LDL cholesterol were significantly reduced (P<0.001), while HDL showed no modifications; triglycerides declined progressively during the 3 y follow-up (P<0.001). Fibrinogen decreased from 364.5+/-82.4 to 266.4+/-45.7 mg/dl at the end of the period (P<0.001). Fasting glucose levels and glucose levels 120 min after an oral glucose tolerance test were reduced from 95.1+/-20.3 to 78.6+/-9.1 mg/dl (P<0.001) and from 116.9+/-34.7 to 77.6+/-15.5 mg/dl (P<0.001), respectively, at baseline and at the end of the study. Moreover, fasting insulin decreased from 30.0+/-20.4 to 8.6+/-2.9 microUI/ml (P<0.001) after 3 y, while insulin levels after (120 min) oral glucose load decreased from 105.5+/-61.5 to 12.0+/-6.0 microUI/ml (P<0.001). CONCLUSION Our results show that biliary-intestinal bypass may represent a valid and alternative therapeutic approach in patients with morbid obesity since it induces a significant and stable reduction of body weight and obesity-related risk factors for CVD.
