The impact of orthostatic intolerance on early ambulation following abdominal surgery in an enhanced recovery programme.

BACKGROUND: The prevalence of orthostatic intolerance on the day of surgery is more than 50% after abdominal surgery. The impact of orthostatic intolerance on ambulation on the day of surgery has been little studied. We investigated orthostatic intolerance and walking ability after colorectal and bariatric surgery in an enhanced recovery programme. METHODS: Eighty-two patients (colorectal: n = 46, bariatric n = 36) were included and analysed in this prospective study. Walk tests for 2 min (2-MWT) and 6 min (6-MWT) were performed before and 24 h after surgery, and 3 h after surgery for 2-MWT. Orthostatic intolerance characterised by presyncopal symptoms when rising was recorded at the same time points. Multivariate binary logistic regressions modelling the probability of orthostatic intolerance and walking inability were performed taking into account potential risk factors. RESULTS: Prevalence of orthostatic intolerance and walking inability was, respectively, 65% and 18% 3-hour after surgery. The day after surgery, patients' performance had greatly improved: approximately 20% of the patients experienced orthostatic intolerance, whilst only 5% of the patients were unable to walk. Adjusted binary logistic regressions demonstrated that age (p = .37), sex (p = .39), BMI (p = .74), duration of anaesthesia (p = .71) and type of surgery (p = .71) did not significantly influence walking ability. CONCLUSION: Our study confirms that orthostatic intolerance was frequent (~ 60%) 3-hour after abdominal surgery but prevented a 2-MWT only in ~20% of patients. No risk factors for orthostatic intolerance and walking inability were evidenced.

Bariatric Surgery in Patients With Inflammatory Bowel Disease: A Case-Control Study from the GETAID.

BACKGROUND: The prevalence of obesity and the number of bariatric surgeries in both the general population and in patients with inflammatory bowel disease (IBD) have increased significantly in recent years. Due to small sample sizes and the lack of adequate controls, no definite conclusions can be drawn from the available studies on the safety and efficacy of bariatric surgery (BS) in patients with IBD. Our aim was to assess safety, weight loss, and deficiencies in patients with IBD and obesity who underwent BS and compare findings to a control group. METHODS: Patients with IBD and a history of BS were retrospectively recruited to centers belonging to the Groupe d'Etude Thérapeutique des Affections Inflammatoires du Tube Digestif (GETAID). Patients were matched 1:2 for age, sex, body mass index (BMI), hospital of surgery, and type of BS with non-IBD patients who underwent BS. Complications, rehospitalizations, weight, and deficiencies after BS were collected in cases and controls. RESULTS: We included 88 procedures in 85 patients (64 Crohn's disease, 20 ulcerative colitis, 1 unclassified IBD) with a mean BMI of 41.6 ± 5.9 kg/m2. Bariatric surgery included Roux-en-Y gastric bypass (n = 3), sleeve gastrectomy (n = 73), and gastric banding (n = 12). Eight (9%) complications were reported, including 4 (5%) requiring surgery. At a mean follow-up of 34 months, mean weight was 88.6 ± 22.4 kg. No difference was observed between cases and controls for postoperative complications (P = .31), proportion of weight loss (P = .27), or postoperative deficiencies (P = .99). CONCLUSIONS: Bariatric surgery is a safe and effective procedure in patients with IBD and obesity; outcomes in this patient group were similar to those observed in a control population.

Laparoscopic Magenstrasse and Mill Gastroplasty (M&M): Midterm Results.

BACKGROUND: The Magenstrasse and Mill gastroplasty (M&M) is a gastric restrictive procedure without band or stomach resection. Short-term evaluation of the laparoscopic procedure showed low morbidity and satisfactory results on weight loss. Evidence of the validity of the technique in the longer term is scarce. METHODS: Data from patients who underwent M&M procedure from May 2012 to September 2015 were retrospectively reviewed. Preoperative clinical characteristics and data up to 4 years after operation were analyzed. RESULTS: A total of 132 patients were included in this study with a mean age of 46 ± 13.4 years. The mean body mass index (BMI) at the time of procedure was 43 ± 4.5 kg/m2. Mean percentage of excess weight loss (%EWL) was 67, 67, 58, and 57% at 1, 2, 3, and 4 years, respectively. The remission rate for diabetes was 36%. About half of the insulin-dependent patients could stop their insulin treatment. Hypertension was resolved in 33.8% of the patients after 4 years. Incidence of vitamin and mineral deficiency was low throughout the study period, less than or equal to 3% for vitamin B12 and 1% for ferritin. Incidence of gastroesophageal reflux did not exceed 15% during the study. Over 75% of the patients reported a good or very good quality of life following the surgery. CONCLUSION: These results confirm the validity of M&M as a bariatric procedure. The low incidence of vitamin deficiencies and gastroesophageal reflux might be the important asset of M&M over other existing techniques.

Prevalence, characteristics and risk factors of chronic postsurgical pain after laparoscopic colorectal surgery: Retrospective analysis.

BACKGROUND: The prevalence of chronic postsurgical pain (CPSP) is a critical medical problem with economic implications. Its prevalence after gastrointestinal surgery is not well documented, particularly when a laparoscopic approach is used. OBJECTIVE: The aim of the study was to determine the prevalence, the characteristics and the risk factors for CPSP after laparoscopic colorectal surgery. DESIGN: A retrospective analysis using a postal questionnaire. SETTING: The study was conducted at a university teaching hospital. PATIENTS: Patients who underwent laparoscopic colorectal surgery from April 2008 until December 2011 (n = 260). No epidural analgesia was used. MAIN OUTCOME MEASURES: Postoperative pain intensity, incidence and characteristics of CPSP, and impact on quality of life and sleep. RESULTS: Of 199 responses, 33 patients (17%) reported chronic pain at a median [interquartile range, IQR] of 38 [27 to 55] months after laparoscopic surgery with a median intensity of 4 [3 to 5]. CPSP had a negative impact on the quality of life in 84% of patients and on sleep in 43%. CPSP required regular analgesic(s) intake in 54% patients. Using a backward stepwise multivariate logistic regression model, the following variables were determined as independent risk factors for CPSP: redo surgery for anastomotic leakage (P = 0.01), inflammatory bowel disease (IBD) as the indication for surgery (P = 0.01) and preoperative pain (P = 0.05). CONCLUSION: The incidence of CPSP after laparoscopic colorectal surgery (17%) is similar to those reported in the literature after laparotomy. Risk factors are redo surgery for postoperative peritonitis, IBD and preoperative pain. TRIAL REGISTRATION: EudraCT 2012-005712-25.

Laparoscopic Magenstrasse and Mill gastroplasty. First results of a prospective study.

BACKGROUND: The Magenstrasse and Mill (M&M) procedure is a vertical gastroplasty creating a tubular pouch extending from the cardia to the antrum. This "incomplete sleeve" avoids gastric resection or band placement. In this paper, we report our experience of the laparoscopic approach of the technique in a selected obese population excluding prominent grazer and/or sweet eaters. MATERIAL AND METHODS: One hundred patients (39 males, 61 females) underwent the procedure in a prospective trial. Mean age was 40 years (range 18-68). Mean preoperative BMI was 43.2 kg/m(2) (range 35-62). RESULTS: The procedure was performed by laparoscopy starting with the creation of a circular opening at the junction of antrum and corpus followed by a vertical stapling to the angle of Hiss. Mean duration of the procedure was 67 (range 40-122) min. No intraoperative complication occurred. Mean hospital stay (SD) was 2.5 (0.9) days. The single postoperative complication consisted in a mild stenosis that responded to endoscopic dilatation. After a mean follow-up of 15 months (range 9-24), mean percentage of excess body weight loss (SD) was 48(14), 59(18) and 68(24)%, respectively at 3, 6, and 12 months. Quality of life appeared satisfactory with a low incidence of gastroesophageal reflux. The procedure was associated with improvement or resolution of diabetes, arterial hypertension, and dyslipemia at 1 year. CONCLUSIONS: Our experience demonstrated that the M&M procedure could be performed safely laparoscopically. The satisfactory results on weight loss, obesity-associated mordities, and quality of life will need to be confirmed on longer follow-up.

Obesity phenotype is related to NLRP3 inflammasome activity and immunological profile of visceral adipose tissue.

AIMS/HYPOTHESIS: Obesity is a heterogeneous condition comprising both individuals who remain metabolically healthy (MHO) and those who develop metabolic disorders (metabolically unhealthy, MUO). Adipose tissue is also heterogeneous in that its visceral component is more frequently associated with metabolic dysfunction than its subcutaneous component. The development of metabolic disorders is partly mediated by the NLR family pyrin domain containing-3 (NLRP3) inflammasome, which increases the secretion of inflammatory cytokines via activation of caspase-1. We compared the immunological profile and NLRP3 activity in adipose tissue between MUO and MHO individuals. METHODS: MHO and MUO phenotypes were defined, respectively, as the absence and the presence of the metabolic syndrome. Cellular composition and intrinsic inflammasome activity were investigated by flow cytometry, quantitative RT-PCR and tissue culture studies in subcutaneous and visceral adipose tissue from 23 MUO, 21 MHO and nine lean individuals. RESULTS: We found significant differences between the three study groups, including an increased secretion of IL-1ß, increased expression of IL1B and NLRP3, increased number of adipose tissue macrophages and decreased number of regulatory T cells in the visceral adipose tissue of MUO patients compared with MHO and lean participants. In macrophages derived from visceral adipose tissue, both caspase-1 activity and IL-1ß levels were higher in MUO patients than in MHO patients. Furthermore, caspase-1 activity was higher in CD11c(+)CD206(+) adipose tissue macrophages than in CD11c(-)CD206(+) cells. CONCLUSIONS/INTERPRETATION: The MUO phenotype seems to be associated with an increased activation of the NLPR3 inflammasome in macrophages infiltrating visceral adipose tissue, and a less favourable inflammatory profile compared with the MHO phenotype.

Laparoscopic repair of paraesophageal hernia. Long-term follow-up reveals good clinical outcome despite high radiological recurrence rate.

OBJECTIVE: The purpose of this report is to evaluate and compare the long-term objective and subjective outcome after laparoscopic paraesophageal hernia repair (LPHR). BACKGROUND: Short-term symptomatic results of LPHR are often excellent. However, a high recurrence rate is detected at objective radiographic follow-up. METHODS: Retrospective review of a prospectively gathered database of consecutive patients undergoing LPHR with and without reinforced crural repair at a single institution. Subjective and objective outcomes were assessed by using a structured symptoms questionnaire, Gastrointestinal Quality-of-Life Index, satisfaction score, and barium esophagogram. RESULTS: From September 1991 to September 2005, LPHR was performed in 85 patients (median age, 66 years) with (25 patients) and without (60 patients) reinforced crural repair. Two patients (3%) underwent laparoscopic reoperation, for severe dysphagia and for symptomatic recurrence, respectively. Subjective outcome, available for 64 patients (75%), improved significantly at median follow-up of 118 months with a postoperative median Gastrointestinal Quality-of-Life Index score of 116. Radiographic recurrence (median follow-up, 99 months) occurred in 23 (66%) of the 35 patients, independently of age at operation, type of paresophageal hiatal hernias, and crural reinforcement, and showed no impact on quality of life. CONCLUSIONS: Although providing excellent symptomatic results, long-term objective evaluation of LPHR reveals a high recurrence rate even with reinforced cruroplasty. A tailored, lengthening gastroplasty and reinforced cruroplasty based on objective intraoperative evaluation, and not only on surgeon's personal judgment, may be the answer to recurrences.

Laparoscopic repair of colonoscopic perforation: a new standard?

BACKGROUND: Scientific evidence demonstrating interest in the laparoscopic approach for surgical repair of colonoscopic perforations is still lacking. The authors retrospectively reviewed the records of 43 patients who suffered from colonic perforations after colonoscopy between 1989 and 2008 in two tertiary centers in order to compare the results of the laparoscopic and the open approaches to repair. METHODS: The patients' demographic data, perforation location, therapy, and outcome were recorded from the medical charts. Forty-two patients were managed operatively (19 laparoscopies and 23 laparotomies). In three patients who underwent explorative laparoscopy, the procedure had to be converted to laparotomy due to surgical difficulties. The patients who underwent laparotomy management had a longer period between the colonoscopy and the surgery (P=0.056) and more stercoral contaminations. RESULTS: The mean hospital stay was shorter for the laparoscopy group (P=0.02), which had fewer postoperative complications (P=0.01) and no mortality (NS). CONCLUSION: This series demonstrates that early laparoscopic management of colonoscopic perforation is safe. Laparoscopic management may lead to reduced surgical and psychological stress for the patient because of its low morbidity and mortality rates and shorter hospital stay. However, the procedure should be converted to a laparotomy if necessary.
