RESUMO
BACKGROUND: Few studies have assessed changes in antihypertensive and lipid-lowering therapy after bariatric surgery. The aim of this study was to assess the 6-year rates of continuation, discontinuation or initiation of antihypertensive and lipid-lowering therapy after bariatric surgery compared with those in a matched control group of obese patients. METHODS: This nationwide observational population-based cohort study used data extracted from the French national health insurance database. All patients undergoing gastric bypass or sleeve gastrectomy in France in 2009 were matched with control patients. Mixed-effect logistic regression models were used to analyse factors that influenced discontinuation or initiation of treatment over a 6-year interval. RESULTS: In 2009, 8199 patients underwent primary gastric bypass (55·2 per cent) or sleeve gastrectomy (44·8 per cent). After 6 years, the proportion of patients receiving antihypertensive and lipid-lowering therapy had decreased more in the bariatric group than in the control group (antihypertensives: -40·7 versus -11·7 per cent respectively; lipid-lowering therapy: -53·6 versus -20·2 per cent; both P < 0·001). Gastric bypass was the main predictive factor for discontinuation of therapy for hypertension (odds ratio (OR) 9·07, 95 per cent c.i. 7·72 to 10·65) and hyperlipidaemia (OR 11·91, 9·65 to 14·71). The proportion of patients not receiving treatment at baseline who were subsequently started on medication was lower after bariatric surgery than in controls for hypertension (5·6 versus 15·8 per cent respectively; P < 0·001) and hyperlipidaemia (2·2 versus 9·1 per cent; P < 0·001). Gastric bypass was the main protective factor for antihypertensives (OR 0·22, 0·18 to 0·26) and lipid-lowering medication (OR 0·12, 0·09 to 0·15). CONCLUSION: Bariatric surgery is associated with a good discontinuation of antihypertensive and lipid-lowering therapy, with gastric bypass being more effective than sleeve gastrectomy.

BACKGROUND: Lifelong medical follow-up is mandatory after bariatric surgery. The aim of this study was to assess the 5-year follow-up after bariatric surgery in a nationwide cohort of patients. METHODS: All adult obese patients who had undergone primary bariatric surgery in 2009 in France were included. Data were extracted from the French national health insurance database. Medical follow-up (medical visits, micronutrient supplementation and blood tests) during the first 5 years after bariatric surgery was assessed, and compared with national and international guidelines. RESULTS: Some 16 620 patients were included in the study. The percentage of patients with at least one reimbursement for micronutrient supplements decreased between the first and fifth years for iron (from 27.7 to 24.5 per cent; P < 0.001) and calcium (from 14·4 to 7·7 per cent; P < 0·001), but increased for vitamin D (from 33·1 to 34·7 per cent; P < 0·001). The percentage of patients with one or more visits to a surgeon decreased between the first and fifth years, from 87·1 to 29·6 per cent (P < 0·001); similar decreases were observed for visits to a nutritionist/endocrinologist (from 22·8 to 12·4 per cent; P < 0·001) or general practitioner (from 92·6 to 83·4 per cent; P < 0·001). The mean number of visits to a general practitioner was 7·0 and 6·1 in the first and the fifth years respectively. In multivariable analyses, male sex, younger age, absence of type 2 diabetes and poor 1-year follow-up were predictors of poor 5-year follow-up. CONCLUSION: Despite clear national and international guidelines, long-term follow-up after bariatric surgery is poor, especially for young men with poor early follow-up.

BACKGROUND: Gastro-oesophageal reflux disease (GORD) is a common obesity-related co-morbidity that is assessed objectively by 24-h pH monitoring. Some concerns have been raised regarding the risk of de novo GORD or exacerbation of pre-existing GORD after laparoscopic sleeve gastrectomy. Here, 24-h pH monitoring was used to assess the influence of laparoscopic sleeve gastrectomy on postoperative GORD in obese patients with or without preoperative GORD. METHODS: From July 2012 to September 2014, all patients scheduled for laparoscopic sleeve gastrectomy were invited to participate in a prospective follow-up. Patients who underwent preoperative 24-h pH monitoring were asked to repeat the examination 6 months after operation. GORD was defined as an oesophageal pH < 4 for at least 4·2 per cent of the total time recorded. RESULTS: Of 89 patients, 76 had preoperative pH monitoring for GORD evaluation and 50 had postoperative reassessment. Patients without (group 1, 29 patients) or with (group 2, 21 patients) preoperative GORD were similar regarding age, sex ratio and body mass index. In group 1, the median (i.q.r.) total time at pH < 4 was significantly higher after surgery than before: 5·6 (2·5-9·5) versus 1·6 (0·7-2·9) per cent (P < 0·001). Twenty of the 29 patients experienced de novo GORD as determined by 24-h pH monitoring (P < 0·001). In group 2, total time at pH < 4 after surgery was no different from the preoperative value: 5·9 (3·9-10·7) versus 7·7 (5·2-10·3) per cent (P = 0·296). CONCLUSION: Laparoscopic sleeve gastrectomy was associated with de novo GORD in over two-thirds of patients, but did not seem to exacerbate existing GORD.

BACKGROUND: The benefit of neoadjuvant chemotherapy (NCT) for early-stage oesophageal cancer is unknown. The aim of this study was to assess whether NCT improves the outcome of patients with stage I or II disease. METHODS: Data were collected from 30 European centres from 2000 to 2010. Patients who received NCT for stage I or II oesophageal cancer were compared with patients who underwent primary surgery with regard to postoperative morbidity, mortality, and overall and disease-free survival. Propensity score matching was used to adjust for differences in baseline characteristics. RESULTS: Of 1173 patients recruited (181 NCT, 992 primary surgery), 651 (55·5 per cent) had clinical stage I disease and 522 (44·5 per cent) had stage II disease. Comparisons of the NCT and primary surgery groups in the matched population (181 patients in each group) revealed in-hospital mortality rates of 4·4 and 5·5 per cent respectively (P = 0·660), R0 resection rates of 91·7 and 86·7 per cent (P = 0·338), 5-year overall survival rates of 47·7 and 38·6 per cent (hazard ratio (HR) 0·68, 95 per cent c.i. 0·49 to 0·93; P = 0·016), and 5-year disease-free survival rates of 44·9 and 36·1 per cent (HR 0·68, 0·50 to 0·93; P = 0·017). CONCLUSION: NCT was associated with better overall and disease-free survival in patients with stage I or II oesophageal cancer, without increasing postoperative morbidity.

INTRODUCTION: Duodenal neuroendocrine tumours (D-NETs) have a low incidence; however, their diagnosis has been increasing. Features such as tumour location, size, type, histological grade, and stage were used to adapt the treatment to either endoscopic (ER) or surgical (SR) resections. There is no consensus regarding the definitive treatment. The authors' study aimed to describe the management of non-metastatic, well-differentiated D-NETs in France and its impact on patient survival. METHODS: A registry-based multicenter study using prospectively collected data between 2000 and 2019, including all patients managed for non-metastatic G1 and G2 D-NETs, was conducted in the GTE group. RESULTS: A total of 153 patients were included. Fifty-eight benefited from an ER, and 95 had an SR. No difference in recurrence-free survival (RFS) was observed regardless of treatment type. There was no significant difference between the two groups (ER vs. SR) in terms of location, size, grade, or lymphadenopathy, regardless of the type of incomplete resection performed or regarding the pre-therapeutic assessment of lymph node invasion in imaging. The surgery allowed for significantly more complete resection (patients with R1 resection in the SR group: 9 vs. 14 in the ER group, P <0.001). Among the 51 patients with positive lymph node dissection after SR, tumour size was less than or equal to 1 cm in 25 cases. Surgical complications were more numerous ( P =0.001). In the sub-group analysis of G1-G2 D-NETs between 11 and 19 mm, there was no significant difference in grade ( P =0.977) and location ( P =0.617) between the two groups (ER vs. SR). No significant difference was found in both morphological and functional imaging, focusing on the pre-therapeutic assessment of lymph node invasion ( P =0.387). CONCLUSION: Regardless of the resection type (ER or SR) of G1-G2 non-metastatic D-NETs, as well as the type of management of incomplete resection, which was greater in the ER group, long-term survival results were similar between ER and SR. Organ preservation seems to be the best choice owing to the slow evolution of these tumours.

INTRODUCTION: Bariatric surgery (BS) leads to substantial weight loss accompanied by reversal of several obesity-related co-morbidities and reduced mortality. However, surgery is associated with risks and its nearly irreversible characteristic requires a clearly established pre- and postoperative clinical pathway. In France, this pathway relies on recommendations made by the High Authority of Health (Haute Autorité de santé (HAS)) in 2009; an update is awaited in 2023. PREOPERATIVE ASPECTS: BS should be proposed only after failure of well-conducted medical treatment and is intended for patients whose body mass index (BMI) is ≥40kg/m2 or for those with BMI ≥35kg/m2 who also have co-morbidities amenable to improvement, and in whom there are no contra-indications, particularly, those related to general anesthesia or psychological factors. The success and safety of surgical management requires preparation of the patient with regard to dietetic and nutritional counseling, and physical activity. The possibility of complications must be recognized and communicated, including, in view of the large variability of outcomes between individuals, the risk of failure and regain of weight. POSTOPERATIVE ASPECTS: Prior to the operation, patients should be informed of and accept the program of postoperative clinical and laboratory follow-up, as well as the need for lifelong supplementation in micronutrients and the financial implications including what patients may have to pay out of their own pocket. CONCLUSION: Surgical management of obesity cannot replace the multidisciplinary medical management of severe obesity. The results obtained by BS are sustainable only if the patient adheres to the proposed modalities. New drugs such a GLP-1 analogues have opened encouraging perspectives as possible alternatives to BS in certain indications.

INTRODUCTION: The French Society of Digestive Surgery (Société Française de Chirurgie Digestive [SFCD]) has elaborated clinical practice guidelines for the management of the obese patient undergoing gastro-intestinal surgery. METHODS: The literature was analyzed according to the GRADE® (Grading of Recommendations Assessment, Development and Evaluation) methodology divided into five chapters: preoperative management, modalities of transportation and installation of the patient in the operating room, specific characteristics related to laparoscopic surgery, specific characteristics related to traditional surgery, and postoperative management. Each question was formulated according to the PICO format (Patients, Intervention, Comparison, Outcome). RESULTS: Synthesis of expert opinions and the application of the GRADE methodology produced 30 recommendations among which three were strong and nine were weak. The GRADE methodology could not be applied for 18 questions, for which only expert opinion was obtained. CONCLUSION: These clinical practice guidelines can help surgeons optimize the peri-operative management of the obese patient undergoing gastro-intestinal surgery.

Despite the high proportion of obese patients this population remains understudied in the field of venous thromboembolic disease (VTE). Obesity is a risk factor for pulmonary embolism and/or deep vein thrombosis, especially when it is associated with other risk factors for VTE. Currently there is no validated diagnostic algorithm for VTE in the population of obese patients. Moreover, imaging examinations can be of poor quality and inconclusive. In the prevention of VTE, data concerning obese patients are mainly based on low-level studies. Apart from the context of bariatric surgery, an adjustment of heparin doses according to the weight of the patient is proposed only on a case-by-case basis. According to the current guidelines, therapeutic fixed dose oral anticoagulants should not be prescribed for patients with weights exceeding 120kg or a body mass index>40kg/m2. Heparin doses should be weight adjusted and monitored with anti-Xa activity. Anti vitamin K can be prescribed but require INR monitoring. Therefore, new studies specifically dedicated to obese patients are required in the field of VTE for better diagnostic and therapeutic management.

OBJECTIVES: To explain the high incidence of misdiagnosis of angiomyolipoma (AML) prior to surgery. MATERIALS AND METHODS: Between 1989 and 2007, 2,657 patients were operated for a renal tumor at Dupuytren hospital in Limoges and at Cochin hospital in Paris. In 85 cases (3.2%), tumors were AMLs on pathology. The group of patients in which the diagnosis was done preoperatively was compared to the one in which the diagnosis was missed. RESULTS: Mean age of patients was 57-years-old and the sex-ratio was five women for one man. The mean size of AMLs was 5.4 cm. The patients were symptomatic in 46% of cases (39/85). The diagnosis of AML was ignored preoperatively in 62 patients (73%). In multivariate analysis, the small size of the AML, low proportion of fat and male sex were significantly associated with misdiagnosis of AML (p<0.001, p<0.018 and p<0.008, respectively). CONCLUSIONS: The incidence of misdiagnosis of AML preoperatively is high. The diagnosis seems particularly difficult when the tumor is small or contains a small proportion of fat. In addition, this study highlights that the diagnosis of AML is frequently ignored in men. The increased resolution of CTscan and the use of preoperative biopsies for tumors less than 4 cm could be helpful to decrease the incidence of useless surgery of AMLs.
