Background
The treatment approach to node-positive gallbladder cancer has unresolved issues with regard to the management of patients with a positive superior retro-pancreatic (level 13a) node, which is the highest level of spread. The American Joint Committee on Cancer remains unclear on the status of the 13a node.Methods
This retrospective study consisted of 165 patients with node-positive gallbladder cancer without distant metastasis. Patients were reclassified according to the American Joint Committee on Cancer eighth edition classification. The survival of patients with positive level 13a node was compared with that of patients with N1 disease (T stage-wise) and those with para-aortic nodal disease. A multivariate analysis was performed for factors affecting survival.Results
The 5-year survival of patients with positive level 13a with 1–3 nodes was similar to those with N1 disease (40.2% and 32.9%, respectively) and was better than those with more distant nodal spread (P < .05). In univariate and multivariate analyses, intraoperative blood loss (hazard ratio [HR] 1.58), R1 resection (HR 1.87), and T4 disease (versus T2, HR 3.44) were poor prognosticators. Pancreaticoduodenectomy may be beneficial in T2 patients.Conclusion
A positive superior retro-pancreatic node does not worsen the prognosis in an otherwise N1 disease in T1/T2 gallbladder cancer. It behaves like a regional lymph node and should be treated as such. 相似文献2.
Background
The aim of this study was to identify the risk factors for structural recurrence with a focus on lymph node–related factors and to determine the optimal cutoff size of lymph node micrometastases in patients with pathologic N1a classical papillary thyroid carcinoma.Methods
We included patients who underwent total thyroidectomy with central compartment lymph node dissection for classic papillary thyroid carcinoma with pathologic N1a classification.Results
A total of 398 patients were followed up for a median of 131 months. Structural recurrence occurred in 17.3% of patients (69/398). The multivariate analysis reported the following independent risk factors for structural recurrence: tumor size >1.95 cm, bilaterality, lymphatic and/or vascular invasion, a maximum diameter of the metastatic lymph node focus >3.5 mm, distribution of metastatic lymph node foci size >3.0 mm, and ≥4 metastatic lymph nodes.Conclusion
The newly proposed cutoff of 3.5 mm for a definition of lymph node micrometastasis in pathologic N1a papillary thyroid carcinoma patients can reclassify the risk estimates of structural recurrence, thus modifying postoperative management plans and follow-up strategies. 相似文献3.

Background
Lateral lymph node dissection has been 1 of the standard treatments for mid and ow rectal cancer in Japan. The aim of this ad-hoc analysis was to evaluate the impact of lateral lymph node dissection on outcomes in the randomized clinical trial, referred to as the Adjuvant Chemotherapy for Stage II/III Rectal Cancer trial.Methods
The Adjuvant Chemotherapy for Stage II/III Rectal Cancer trial was a randomized, phase III trial of adjuvant chemotherapy of 2 different oral fluoropyrimidines; 445 patients with lower rectal cancer were studied in this ad-hoc analysis out of 959 patients in total, 215 of whom underwent lateral lymph node dissection and 230 did not.Results
There were no significant differences in background characteristics of the patients in the group, except for in age and number of dissected lymph nodes, between the lateral lymph node dissection and without lateral lymph node dissection groups. The age of the younger patients was often used to select candidates for lateral lymph node dissection (lateral lymph node dissection versus non–lateral lymph node dissection; 63.5 ± 8.9 vs 60.7 ± 9.4 [P?=?.0017]). Lateral lymph node dissection had no impact on relapse-free survival (hazard ratio?=?0.941, 95% confidence interval: 0.696–1.271) or overall survival (hazard ratio?=?0.858, 95% confidence interval: 0.601–1.224) in all patients with mid and low rectal cancer. In subset analysis, lateral lymph node dissection improved relapse-free survival in female patients and in patients with stage B/C or N3/4 disease. For cumulative recurrence across all patients, the proportion of patients with distant recurrence was slightly greater in the lateral lymph node dissection group but there was no difference in local recurrence.Conclusion
This exploratory analysis did not show that lateral lymph node dissection improves relapse-free survival and overall survival in patients with mid and low rectal cancer. Lateral lymph node dissection may, however, have a prognostic impact on patients with highly invasive rectal cancer. 相似文献4.

Background
The recurrence patterns of high-risk, N1 prostate cancer after radiation therapy (RT) including the pelvic lymph nodes have not been fully investigated.Material and methods
We have a prospective clinical study since 2004 that has followed 138 men with locally advanced prostate cancer (T1-T4N0-N1M0) treated with definitive RT encompassing the prostate and pelvic lymph nodes and long-term androgen deprivation therapy (ADT). Forty nine of the 52 patients that developed recurrence were imaged at biochemical failure to detect the site of recurrence.Results
Imaging identified the site of recurrence in 46 patients. Twenty five patients had prostatic recurrence only, none had local lymph node recurrence only, 11 had distant metastases only, 7 had prostatic recurrence and distant metastases, 2 had prostatic recurrence, local nodal recurrence and distant metastases, and 1 had local nodal recurrence with distant metastases. The mean time to recurrence was 62 months for prostate only, 40 months for distant only and 50 months for prostate and distant recurrence. There was a 69% recurrence rate for patients with magnetic resonance imaging -detected N1 disease. There was significantly longer survival for patients with prostate recurrence only compared to patients with distant recurrence (P < 0.018). Five-year prostate cancer-specific survival were 85% for prostate only, 44% for distant only and 48% for prostate and distant recurrence (prostate only vs. distant only; P = 0.008, prostate only vs. prostate and distant; P?=?0.018, distant vs. prostate and distant; P = 0.836).Conclusions
The predominant recurrence pattern for high-risk, N1 prostate cancer was prostatic recurrence and distant spread after pelvic RT and androgen deprivation therapy. Our data argue for further local dose escalation and pelvic nodal radiation to prevent recurrence in these sites. Lymph node metastasis at initial staging with an magnetic resonance imaging was a strong predictor of recurrence and poor survival and may identify patients in need of more aggressive treatment. 相似文献5.

Introduction
Renal cell carcinoma (RCC) brain metastasis is generally viewed as poor prognostic features and often excludes patients from cytoreductive nephrectomy or participation in clinical trials. We aim to evaluate patients presenting with brain metastasis and their outcomes.Methods
Surveillance Epidemiology and End Results-18 registries database was queried for all patients with metastatic RCC from 2010 to 2014. Patients with renal cancer as their only malignancy were included. Information was available for metastatic disease to bone, liver, lung, and brain. Patients were then further stratified into those with isolated brain metastases and those with additional metastasis to other sites as well. Overall survival was compared between groups using logrank analysis.Results
A total of 6,667 patients were identified with metastatic RCC. Among them, 775 (12.1%) had brain metastasis at time of diagnosis. Of these patients with brain metastasis, 152 (20.4%) had isolated brain metastasis. Only 23.8% of all patients with brain metastasis underwent cytoreductive nephrectomy, compared to 40.8% of patients with isolated brain metastasis. Patients with brain and other metastasis and brain metastasis only treated by cytoreductive nephrectomy exhibited a median survival of 11 and 33 months, respectively. Those patients who did not undergo cytoreductive nephrectomy experienced a median survival of 4 and 5 months, respectively.Conclusion
It appears that selected patients with brain metastasis may experience durable long-term survival. This information may be beneficial for patient counseling, surgical planning, and consideration for inclusion in clinical trials. 相似文献7.

Objectives
Urothelial cell carcinoma (UCC), a major malignancy of the genitourinary tract, is induced through carcinogenic etiological factors. Endothelial nitric oxide synthase (eNOS) is one of the major isoforms of nitric oxide synthase and is involved in various pathophysiologic and physiologic processes. In this study, eNOS single-nucleotide polymorphisms were investigated to evaluate UCC susceptibility and clinicopathological characteristics.Materials and methods
Two single-nucleotide polymorphisms of eNOS in 431 patients with UCC and 862 controls without cancer were analyzed using real-time polymerase chain reaction.Results
The results showed that 272 men with UCC having eNOS 894 G > T rs1799983 “GT?+?TT” variants had a high risk of developing a large tumor (T1–T4, P?=?0.038). Furthermore, a correlation was observed between the expressions of eNOS and invasive tumor, metastasis and poor survival in urothelial carcinoma in The Cancer Genome Atlas data set.Conclusion
Our results indicated that male patients with UCC carrying eNOS 894 G > T rs1799983 “GT?+?TT” genetic variants have a high risk of developing a large tumor, and eNOS polymorphisms may serve as a marker or therapeutic target in UCC treatment. 相似文献8.
Objectives
To assess the relationship between nodal disease burden and overall survival (OS) among patients with lymph node (LN) metastases from renal cell carcinoma (RCC)Methods
The National Cancer Data Base was used to identify 2,975 patients with RCC who were treated with radical nephrectomy and were found to have regional LN metastases. Associations between the number of positive and negative LN removed and OS were assessed using Cox proportional hazards regression. The median follow-up time among survivors was 3.6years.Results
The median number of positive LN was 1 (interquartile range 1–3). A higher number of positive LN was associated with higher all-cause mortality on multivariable analysis (HR 1.06 per 1 positive LN, 95% CI 1.04, 1.07, P < 0.001). Conversely, higher negative LN counts were associated with better OS (HR 0.97 per 1 negative LN, 95% CI 0.96, 0.99, P < 0.001). The adjusted probability of a patient with 1 LN removed that was positive surviving at least 2 years was 56%, a figure that increased to 64% when 1 out of 10 LN removed was positive and decreased to 38% when 10 out of 10 LN removed were positive.Conclusions
Ours is the first study to show that differences in nodal disease burden translate into clinically significant differences in survival among patients with LN metastases from RCC. 相似文献9.

Background
The essence of enhanced recovery after surgery (ERAS) program is the multimodal approach, and many authors have demonstrated safety and feasibility in fast-track bariatric surgery.Objectives
The aim of this study was to evaluate the postoperative pain after the implementation of an ERAS protocol in Roux-en-Y gastric bypass and to compare it with the application of a standard care protocol.Setting
University Hospital Rey Juan Carlos, Madrid, Spain.Methods
A prospective randomized clinical trial of all the patients undergoing Roux-en-Y gastric bypass was performed. Patients were randomized into the following 2 groups: those patients after an ERAS program and those patients after a standard care protocol. Postoperative pain, nausea or vomiting, morbidity, mortality, hospital stay, and analytic acute phase reactants 24 hours after surgery were evaluated.Results
One hundred eighty patients were included in the study, 90 in each group. Postoperative pain (16 versus 37 mm; P < .001), nausea or vomiting (8.9% versus 2.2%; P?=?.0498), and hospital stay (1.7 versus 2.8 d; P < .001) were significantly lower in the ERAS group. There were no significant differences in complications, mortality, and readmission rates. White blood cell count, serum fibrinogen, and C reactive protein levels were significantly lower in the ERAS group 24 hours after surgery.Conclusion
The implementation of an ERAS protocol was associated with lower postoperative pain, reduced incidence of postoperative nausea or vomiting, lower levels of acute phase reactants, and earlier hospital discharge. Complications, reinterventions, mortality, and readmission rates were similar to that obtained after a standard care protocol. 相似文献10.

Background
For a number of years the laparoscopic adjustable gastric band has been one of the leading bariatric procedures with good short-term outcomes. However, inadequate weight loss, weight regain, and other band-related complications in the long term led to an increase in revisional Roux-en-Y gastric bypass (RYGB) procedures. Lengthening the biliopancreatic limb, a relatively simple and safe adjustment of the standard technique, could improve the results of the revisional procedure.Objectives
The aim of this randomized controlled trial was to evaluate the effect of a long biliopancreatic limb RYGB (LBP-GB) and standard RYGB (S-GB) as revisional procedure after laparoscopic adjustable gastric band.Setting
General hospital specialized in bariatric surgeryMethods
One hundred forty-six patients were randomized in 2 groups; 73 patients underwent an S-GB (alimentary/biliopancreatic limb 150/75 cm), and 73 patients underwent LBP-GB (alimentary/biliopancreatic limb 75/150). Weight loss, remission of co-morbidities, quality of life, and complications were assessed during a period of 4 years.Results
Baseline characteristics between the groups were comparable. At 48 months the follow-up rate was 95%. Mean total weight loss after 24 months was 27% for LBP-GB versus 22% S-GB (P?=?.015); mean total weight loss after 48 months was 23% and 18%, respectively (P?=?.036). No significant differences in other parameters were found between the groups.Conclusions
A LBP-GB as revisional procedure after a failing laparoscopic adjustable gastric band improves short- and long-term total weight loss compared with an S-GB. Together with future modifications this technically simple adjustment of the RYGB could significantly improve disappointing results after revisional surgery. 相似文献11.

Background
Though intestinal failure (IF) after bariatric surgery (BS) is uncommon, its prevalence is increasing. However, data on the outcomes for these patients are limited.Objectives
To analyze the outcomes of treatment for patients with IF after BS.Setting
University hospital.Methods
A single-center analysis (1991–2016) of outcomes according to treatment arms established by a multidisciplinary team.Results
Twenty-five IF patients were identified (median age 45 yr). BS was 92% Roux-en-Y gastric bypass. The major cause of IF was volvulus/internal hernia (72%). Median time from BS to IF was 48 months. Treatment arms were intestinal rehabilitation (IR, n?=?15), transplantation (TXP, n?=?5), and parenteral nutrition (PN, n?=?5). For IR, median bowel length was 60 cm. Forty-six percent ultimately discontinued PN. Twenty-seven percent were partially weaned PN and 27% failed IR. Common surgical rehabilitation was Roux-en-Y gastric bypass reversal and restoration of gastrointestinal continuity. The 5-year overall survival was 74%. For TXP, 7 patients were listed for TXP (5 initially and 2 after failed IR). Three underwent TXP, 2 isolated intestine and 1 isolated liver. Three were delisted (1 improvement and 2 death). For PN, 6 patients required long-term PN (5 initially and 1 after failed IR). Four patients are alive currently.Conclusions
IF after BS is an increasing problem facing IR centers. Internal hernia is the major cause. Surgical IR is the first-line therapy and affords the best outcome. TXP is reserved for rescuing patients who failed IR or develop PN complications. Long-term PN is suitable for patients in whom IR or TXP is impractical. 相似文献12.

Objective
To create multivariable models with readily available clinicopathologic variables for predicting the prognosis of upper tract urothelial carcinomas (UTUC).Patients and methods
We retrospectively analyzed patients diagnosed as UTUC and underwent radical nephroureterectomy in 2 high volumes, tertiary care centers. A total of 445 patients and 227 patients met the inclusion criteria were included for constructing the prediction model and external validation, respectively. Univariable and multivariable Cox regression models were used to analyze independent risk factors, and nomogram and calibration curve were constructed by R project.Results
The median follow-up for the development and external validation cohorts were 33.5 and 32.5 months, respectively. Multivariable analysis detected older age (≥65 years), with concurrent bladder cancer at diagnosis, with both ureter and renal pelvic tumor, lymphovascular invasion, urothelial carcinoma with divergent differentiation, higher pathological grade and stage, and positive lymph node were significantly associated with poorer outcome of UTUC. The c-index of the nomogram with these above-mentioned independent risk factors to predict the cancer specific survival was 0.74 (95% CI, 0.64–0.84) and 0.73 (95%CI, 0.59–0.87) for the development cohort and external validation cohort, respectively.Conclusions
We developed and externally validated a novel and accurate nomogram with readily available clinicopathological information for predicting the cancer specific survival of UTUC. This nomogram could help clinicians stratify patients with UTUC into different risk groups with distinct prognosis by the total scores obtained from the prediction tool, thus facilitate decision-making and clinical trial designing. 相似文献13.

Background
Bariatric surgery can lead to changes in the oral absorption of many drugs. Levothyroxine is a narrow therapeutic drug for hypothyroidism, a common condition among patients with obesity.Objective
The purpose of this work was to provide a mechanistic overview of levothyroxine absorption, and to thoroughly analyze the expected effects of bariatric surgery on oral levothyroxine therapy.Methods
We performed a systematic review of the relevant literature reporting the effects of bariatric surgery on oral levothyroxine absorption and postoperative thyroid function. A PubMed search for relevant keywords resulted in a total of 14 articles reporting levothyroxine status before versus after bariatric surgery.Results
Different mechanisms may support opposing trends as to levothyroxine dose adjustment postsurgery. On the one hand, based on impaired drug solubility/dissolution attributable to higher gastric pH as well as reduced gastric volume, compromised levothyroxine absorption is expected. On the other hand, the great weight loss, and altered set-point of thyroid hormone homeostasis with decreased thyroid-stimulating hormone after the surgery, may result in a decreased dose requirement.Conclusions
For patients after bariatric surgery, close monitoring of both the clinical presentation and plasma thyroid-stimulating hormone and T4 levels is strongly advised. Better understanding and awareness of the science presented in this article may help to avoid preventable complications and provide optimal patient care. 相似文献14.

Background
Although Roux-en-Y gastric bypass (RYGB) results in significant weight loss and cardiometabolic risk factors improvements; there is no consensus whether limb lengths may influence these results.Objective
To evaluate the correlations between the common limb length (CLL) and hypertension remission rate, cardiometabolic risk factors, and nutritional parameters after RYGB.Settings
Private Hospital, Brazil.Methods
GATEWAY is a randomized trial designed to evaluate the efficacy of RYGB on hypertension improvement and other cardiometabolic risk factors in patients with grade I and II obesity compared with medical therapy. The follow-up was 1 year. We measured the entire bowel in all patients and used a 150-cm alimentary limb and a 100-cm biliopancreatic limb. Univariate logistic regression was used to estimate the relationship between CLL and hypertension remission. Pearson and Spearman correlation were used to evaluate the correlation between the CLL and the percentage changes of cardiometabolic risk factors and nutritional parameters.Results
From 100 randomized patients, 45 were submitted to RYGB and completed the follow-up. Mean CLL was 466.3 ± 86.4 cm. Of patients, 55.6% from the RYGB group showed remission of hypertension. CLL length was not significantly associated with hypertension remission (odds ratio [95% confidence interval] for 50 units increase in CLL: .97 [.68; 1.38], P?=?.88). Consistently, we found no correlations between CLL and all changes in cardiometabolic risk factors and nutritional parameters.Conclusions
In a proximal RYGB, CLL does not influence hypertension remission, cardiometabolic risk factors, and nutritional parameters. 相似文献15.

Background
Single-anastomosis duodeno-jejunal bypass with sleeve gastrectomy (SADJB-SG) was developed as a simplified technique of DJB-SG, but long-term data are lacking.Objective
To report the long-term data of SADJB-SG.Setting
Tertiary Teaching Hospital.Methods
A total of 148 SADJB-SG was performed from 2011 to 2016 with mean age of 42.0 ± 10.9-years old (14–71), female 64.9%, and mean body mass index 34.2 ± 5.9 kg/m2. All patients were evaluated and managed under a strict multidisciplinary team approach. A retrospective analysis of a prospective bariatric database and telephone interview of patients who defaulted clinic follow-up at 5-year was conducted.Results
The mean operating time, intraoperative blood loss, and hospital stay of SADJB-SG were 189.6 ± 32.1 minutes, 43.5 ± 17.9 mL, and 5.0 ± 5.1 days, respectively. The 30-days postoperative major complication occurred in 7(4.7%) patients, all in patients with type 2 diabetes (T2D). At postoperative 1, 2, and 5 years, the mean percentage of total weight loss and excess weight loss of SADJB-SG patients were 25.5%, 22.8%, 22.5%, and 83.9%, 76.1%, 58.6%, respectively. Among 118 patients with T2D, 62 (52.5%) achieved complete remission (hemoglobin A1C <60%) at 1 year and 36.5% at 5 years after surgery. A total of 15 patients needed reoperation at follow-up, due to reflux disease (n?=?11), weight regain, and recurrent of T2D (n?=?2), ileus (n?=?1), and peritonitis (n?=?1). Among them, 8 were converted to RYGB and the others remained in same anatomy. At 5 years, the overall revision rate was 12.9% (8/62) and 24.5% (14/57) of the remaining required proton pump inhibitor for reflux symptoms.Conclusion
Our results show that primary SADJB-SG is a durable primary bariatric procedure with sustained weight loss and a high resolution of T2D at 5 years, but de novo GERD is the major side effect. 相似文献16.

BACKGOUND CONTEXT
Abnormal proximal femoral angle (PFA) was recently found to be associated with deteriorating sagittal balance and quality of life (QoL) in high-grade spondylolisthesis (HGS). However, the influence of PFA on the QoL of patients undergoing surgery remains unknown.PURPOSE
This study compares the pre- and postoperative measurements of sagittal balance including PFA in patients with lumbosacral HGS after surgery. It also determines if PFA is a radiographic parameter that is associated with QoL in patients undergoing surgery.STUDY DESIGN
Retrospective cohort study.PATIENT SAMPLE
Thirty-three patients (mean age 15.6 ± 3.0 years) operated for L5-S1 HGS between July 2002 and April 2015. Thirteen had in situ fusion and 20 had reduction to a low-grade slip.OUTCOME MEASURES
The outcome measures included PFA and QoL scores measured from the Scoliosis Research Society SRS-30 QoL questionnaire.METHODS
The minimum follow-up was 2 years. PFA and QoL were compared pre- and postoperatively. Statistical analysis used nonparametric Mann-Whitney and Wilcoxon Signed Rank tests, Chi-square tests to compare proportions, and bivariate correlations with Spearman's coefficients.RESULTS
A decreasing PFA correlated with less pain (r = ?0.56, p?=?.010), improved function (r = ?0.51, p?=?.022) and better self-image (r = ?0.46, p?=?.044) postreduction. Reduction decreased PFA by 5.1° (p?=?.002), whereas in situ fusion did not alter PFA significantly. Patients with normal preoperative PFA had similar postoperative QoL regardless of the type of surgery, except for self-image, which improved further with reduction (3.73 ± 0.49 to 4.26 ± 0.58, p?=?.015). Patients with abnormal preoperative PFA tended to have a higher QoL in all domains after reduction.CONCLUSION
Decreasing PFA correlates with less pain, better function and self-image. Reduction of HGS decreases PFA. Reduction also relates to a better postoperative QoL when the preoperative PFA is abnormal. When the preoperative PFA is normal, in situ fusion is equivalent to reduction except for self-image, which is better improved after reduction. 相似文献17.

Background
Among the population of morbidly obese people, super-super-obese (SSO) individuals (body mass index >60 kg/m2) present a treatment challenge for bariatric surgeons.Objectives
To compare the long-term outcomes between laparoscopic sleeve gastrectomy (SG) and laparoscopic Roux-en-Y gastric bypass (RYGB) and to evaluate the efficacy of SG as a stand-alone bariatric procedure for SSO patients.Setting
University hospital, Paris, France.Methods
We retrospectively reviewed the data outcomes of 210 SSO patients who underwent SG or RYGB between January 2000 and December 2011. The 6-year follow-up data were analyzed and compared.Results
Follow-up data at 6 years were collected for 57.1% and 52.1% of patients in the SG group and RYGB groups, respectively. Both procedures were effective at promoting weight loss. Most weight loss was achieved at 24 months with both procedures. The average percent excess weight loss and change in body mass index of SG versus RYGB showed no significant differences at the 4-year follow-up. Except for sleep apnea, RYGB showed slightly better resolution of the evaluated co-morbidities. The composite endpoint of major short-term adverse events (<30 d) occurred in 11.7% of patients with RYGB and 6.4% of those with SG (P?=?.02). Postoperative complications were seen in 26% of RYGB patients and 16.1% of SG patients.Conclusions
SG as a primary procedure for SSO patients remains effective even though RYGB achieves better midterm outcomes. SG can be proposed as the primary-option p+rocedure. Further investigations are needed to identify the ideal procedure for patients with symptoms of gastroesophageal reflux disease. 相似文献18.

Background
In bariatric surgery, preoperative very low-calorie diets (VLCD) may better meet the technical demands of surgery by shrinking the liver. However, diets may affect tissue healing and influence bowel anastomosis in an as-yet-undefined manner.Objective
This randomized controlled trial aimed to examine the effect on collagen deposition in wounds in patients on a 4-week VLCD before laparoscopic gastric bypass.Setting
University hospital.Methods
The trial was undertaken in patients undergoing laparoscopic Roux-en-Y gastric bypass, with a control group (n?=?10) on normal diet and an intervention group (n?=?10) on VLCD (800 kcal) for 4 weeks. The primary outcome measured was expression of collagen I and III in skin wounds, with biopsies taken before and after the diet and 7 days postoperatively as a surrogate of anastomotic healing. Secondary outcome measures included liver volume and fibrosis score, body composition, operating time, blood loss, hospital stay, and complications.Results
Patients in both groups were similar in age, sex, body mass index (53.4 versus 52.8 kg/m2), co-morbidities, liver volume, and body composition. Expression of mature collagen type I was significantly decreased in diet patients compared with controls after 4 weeks of diet and 7 days after surgery. This was significant decrease in liver volume (23% versus 2%, P?=?.03) but no difference in operating times (129 versus 139 min, P?=?.16), blood loss, length of stay, or incidence of complications.Conclusions
Preoperative diets shrink liver volume and decrease expression of mature collagen in wounds after surgery. Whether the latter has a detrimental effect on clinical outcomes requires further evaluation. 相似文献19.

Background
Obesity is associated with an increased risk of atrial fibrillation (AF). Bariatric surgery results insubstantial long-term weight loss and the amelioration of several chronic comorbidities. We hypothesized that weightreduction with bariatric surgery would reduce the long-term incidence of AF.Objectives
To assess the association between bariatric surgery and AF prevention.Setting
University Hospital, United States.Methods
All patients who underwent bariatric surgery at a single institution from 1985–2015 (n?=?3,572) were propensity score matched 1:1 to a control population of obese patients with outpatient appointments (n?=?45,750) in our clinical data repository. Patients with a prior diagnosis of AF were excluded. Demographics, relevant comorbidities, and insurance status were collected and a chart review was performed for all patients with AF. Paired univariate analyses were used to compare the two groups.Results
After propensity score matching, 5,044 total patients were included (2,522 surgical, 2,522 non-surgical). There were no differences in preoperative body mass index (BMI) (47.1 vs 47.7 kg/m2, P?=?0.76) or medical comorbidities between groups. The incidence of AF was lower among surgical patients (0.8% vs 2.9%, P?=?0.0001). In patients ultimately diagnosed with AF, time from enrollment to development of AF did not differ between groups; however, surgical patients with AF experienced a significantly higher reduction in excess BMI compared to non-surgical patients with AF (57.9% vs ?3.8%, P<0.001).Conclusion
The incidence of AF was lower among patients who underwent bariatric surgery compared to their medically managed counterparts. Weight reduction with bariatric surgery may reduce the long-term incidence of AF. 相似文献20.
