There are currently few pre-operative predictors of initial and long-term weight loss following bariatric surgery.

We evaluated the role of pre-operative patient characteristics and baseline gut and adipose-derived hormones in predicting maximal total body weight loss (WL
) and risk of weight regain (WR) after Roux-en-Y gastric bypass (RYGB) surgery.

One hundred five adult patients undergoing primary RYGB were prospectively recruited. Baseline demographics were recorded and fasting plasma glucose, glycosylated hemoglobin (A1C), insulin, glucagon, leptin, active ghrelin, glucagon-like peptide 1 (GLP-1), and glucose-dependent insulinotropic polypeptide (GIP) levels were measured on day of surgery.

Our cohort had a mean age of 44.4 ± 13.0years, and initial BMI (body mass index) of 45.1 ± 6.7kg/m
with mean post-operative follow-up of 40months. Eighty patients were female and 26 had type 2 diabetes mellitus (T2D). Average WL
was 35.3 ± 7.4%. On univariate analysis, higher baseline fasting ghrelin, lower age, lower CRP (C-reactive protein), lower A1C, and negative T2D status were associated with greater WL
(p < 0.05). Controlling for these variables using stepwise multivariate regression, only higher fasting ghrelin and younger age were associated significantly with greater WL
(p < 0.05). In subgroup multivariate regression analysis of T2D patients, higher ghrelin and glucagon were significantly associated with greater WL
. Following stepwise multivariate regression, lower initial BMI and lower glucagon were associated with greater WR (p < 0.05).

Incorporation of baseline biological and hormonal markers may help in developing more accurate predictive models for weight loss following bariatric surgery that help inform patient counseling and decision-making.

The clinical diagnosis of an internal herniation (IH) after a Roux-en-Y Gastric Bypass (RYGB) remains difficult; therefore, performing a CT scan is usually part of the diagnostic process. The goal of this study was to assess the incidence of IH in patients with open and closed MD (mesenteric defect) and to study if the ability to diagnose an IH with a CT scan is different between these groups.

IH was defined as a visible intestine through the mesenteric defect underneath the jejunojejunostomy and/or in the Petersen's space. CT scan outcomes were compared with the clinical diagnosis of an IH. Until 31 June 2013, standard care was to leave mesenteric defects (MDs) open; after this date, they were always closed.

The incidence of IH in the primarily non-closed group was 3.9%, and in the primarily closed group, this was 1.3% (p = 0.001). In group A (non-closed MD and CT), the sensitivity of the CT scan was 80%, and specificity was 0%. In group C (closed MD and CT), the sensitivity was 64.7%, and specificity was 89.5%. In group B (non-closed, no CT), an IH was visible in 58.7% of the cases and not in 41.3%. In group D (only a re-laparoscopy), an IH was visible in 34.3% of the cases and not in 65.7%.

Using the CT scan in suspected IH is not useful in if the MDs were not closed. If the MDs were closed, then a CT scan is predictive for the diagnosis IH.

This study estimated the eligible population and the unmet need for metabolic surgery within English regions. Health Survey for England, National Diabetes Audit and population estimates were used to estimate the metabolic surgery eligible population by English region. Hospital Episode Statistics data was examined for metabolic surgery procedure volume by region (2013-2019). Regression analysis examined factors associated with metabolic surgery eligibility. 7.3% of the English population is potentially eligible for metabolic surgery; equivalent to 3.21 million people. Only 0.20% of the eligible English population receive metabolic surgery per year (regional variation 0.08-0.41%). The metabolic surgery eligible population was more likely to be female, older, have fewer educational qualifications and live in more deprived areas.
The effect of bariatric surgery on thyroid hormone changes yielded inconsistent results. The aim of the present study was to assess the change of thyroid hormone levels following laparoscopic sleeve gastrectomy (LSG), with or without antral preservation (AP).

Thyroid hormones (TSH, FT3, FT4) were examined preoperatively, at the end of the first postoperative month, and first postoperative year. Secondly, antral resection (AR) and AP were compared at inducing weight loss and thereby affecting thyroid hormone levels.

Euthyroid obese patients (86 female/20 male) underwent LSG. Of these, 58 patients underwent AR and 48 patients AP. The mean FT3 levels significantly decreased both in the first postoperative month and the first year (P < 0.001), whereas mean TSH levels decreased significantly in the first postoperative year (P < 0.001). FT4 levels remained nearly unchanged (P = 0.517). Postoperative first year body mass index (BMI) loss, excess BMI loss percentile (%EBMIL), and total body weight loss percentile (%TWL) were significantly higher in AR group than the AP group (P ≤ 0.01). When the change in thyroid hormone levels was analyzed by pyloric distance according to time periods, no significant difference was found in TSH and FT4 levels (P > 0.05); however, reduction in FT3 levels was significantly greater in patients with AR than in AP patients (P = 0.028).

LSG promotes significant reduction in TSH and FT3 levels, whereas FT4 levels remain unchanged. LSG with AR provides more weight loss in short term and appears to be more effective at lowering FT3 levels.

Standardization of the sleeve gastrectomy technique may potentially minimize the volume inconsistency and improve outcomes. A volume and pressure-sensitive gastric calibration tube may create a standard sleeve size and minimize interoperator variation. The objective of preliminary testing was to establish the variability of sleeve gastrectomy size in gastric explants, and to compare that with the variability of sleeve gastrectomy size when performed with a volume and pressure-sensitive gastric calibration tube. Three operators performed six sleeve gastrectomies each on commercially processed porcine gastric explants, half with a 40 Fr bougie, and a half with a pressure-sensing and volume-controllable gastric calibration tube prototype. The resulting sleeves were evaluated using standard statistical methods. The pressure-sensitive gastric calibration tube demonstrated superior consistency to a standard 40 Fr bougie by common measures of variation. However, further investigation is warranted to characterize the significance of this difference.
Although tracheobronchial diverticulum (DV) rarely cause problems, attention should be paid during esophagectomy, which requires careful dissection around the trachea and bronchi. Here, we retrospectively review cases of tracheobronchial DVs among esophageal cancer patients and report two cases of bronchial DV injury during thoracoscopic esophagectomy that were successfully repaired.

The thin-section CT images of esophageal cancer patients who underwent thoracoscopic esophagectomy from January 2013 to December 2015 were retrospectively reviewed. selleck The localization, number, and size (largest axial diameter) of all detected DVs were recorded.

A total of 180 patients were enrolled in this study. The incidence of tracheal DV was 5.0%, and that of bronchial DV was 40.0%. The median diameter of the tracheal diverticula was 2.45 [interquartile range (IQR) 2.00-8.17] mm and that of the bronchial diverticula was 1.90 (IQR 1.51-2.46)mm. All tracheal diverticula presented at the right tracheal wall 4.5-6.0cm below the vocal cords; bronchial diverticula presented at the subcarinal lesions. We experienced two cases with bronchial diverticulum injuries during thoracoscopic esophagectomy, which were repaired by primary closure and confirmed that there was no air leak. No postoperative complications associated with bronchial injury occurred in either patient.

Since tracheobronchial DVs are not as rare as previously thought, careful evaluation of thin-slice CT scans is necessary before thoracoscopic esophagectomy. If a tracheobronchial DV is injured during surgery, it is important to carefully repair it and confirm that there is no air leak to avoid complications.

The aim of this study was to investigate the effects of bivalirudin on endothelial cell proliferation and neointimal hyperplasia in a rabbit carotid artery model.

"New Zealand rabbits (n = 12)" weighing 2-3kg were randomly divided into two groups. Arteriotomy was performed to the rabbit carotid artery and closed with continuous suture technique. Group B (n = 6) as a control group received 150U/kg heparin sodium; however, group A (n = 6) was given 0.75mg/kg bivalirudin i.v. bolus and infusion 1.75mg/kg/hour (B01AE06-Bivalirudin 250mg) during perioperation period. At the end of the 28th day, the carotid artery segment was excised and evaluated histologically.

All histological and immune staining analyzes were performed by two blind researchers in the treatment of rabbits. In the control group rabbit carotid artery sections, tunica intima was observed to thicken. In the bivalirudin group, intimal hyperplasia was less observed compared to the control group. No significant difference was observed between groups in tunica media thickness. Lumen diameter and lumen area were found to be wider in the experimental group. P value was found to be less than 0.05.

Our study demonstrates that bivalirudin significantly affects and prevents neointimal hyperplasia and endothelial cell proliferation.

Circulating tumor cells (CTCs) as a noninvasive detection technology have become a research hotspot in the field of precision medicine. However, CTC detection faces great challenges with respect to specificity and sensitivity.

We divided 39 subjects into three groups renal carcinoma, renal stones and healthy persons. Using subtraction enrichment (SE) combined with immunostaining-fluorescence in situ hybridization technology, we identified and characterized CTCs. CTCs were identified as DAPI +/CD45-/PanCK + (-). We explored whether the number of CTCs was related to clinicopathological factors and their clinical application.

The CTC count in the renal carcinoma group (29/39) was 86.20% using a cut-off value of 1 CTC, which was significantly higher than that of other technologies in detecting CTCs, demonstrating that SE-iFISH technology can be used for CTC detection. The CTC count was much higher in the renal carcinoma group than that in the other control groups, with an area under the ROC curve of 0.931 (95% confidence interval 0.
