Outcomes of Sleeve Gastrectomy in Septuagenarians

Background

Few previous studies have assessed the safety of bariatric surgery in septuagenarians.

Methods

A retrospective analysis of all patients 70 years or older who underwent laparoscopic sleeve gastrectomy at our institution between 2012 and 2017 was performed. This group was compared to a matched cohort of younger LSG patients (18–50 years) who were operated during the same time period.

Results

Thirty septuagenarian LSG patients were compared to 60 younger patients. Gender distribution, preoperative weight, and preoperative body mass index (BMI) were comparable, although patients in the older age group suffered from more preoperative comorbidities (100 vs. 51.7%, p?<?0.001). Operative time was longer (77.2 vs. 57.3 min, p?=?0.005) and more hiatal hernias were repaired (46.7 vs. 8.3%, p?<?0.001) in the older age group. Intraoperative complications occurred more in the older age group (6.7 vs. 0%, p?=?0.04) but the overall complication rate (13.3 vs. 5.0%, p?=?0.17) and the postoperative complication rate (10.0 vs. 5.0%, p?=?0.38) were comparable. After a mean follow-up period of 31.3 and 33.5 months, the percentage of total body weight loss was 24.6 and 28.3% for the older and younger patients, respectively (p?=?0.11). Rates of improvement/remission of comorbidities were comparable between the groups.

Conclusions

In a carefully selected group of severely obese patients ≥?70 years old, LSG may be safe, with acceptable postoperative complication rates, weight loss results, and improvement in comorbidities.

     

Gastric Bypass in Older Patients: Complications,Weight Loss,and Resolution of Comorbidities at 2 Years in a Matched Controlled Study

Background

Roux-en-Y gastric bypass (RYGB) has recently been authorized for use in older patients. The objective of this single-center study was to evaluate 2-year weight loss in patients ≥60 years compared with younger matched patients undergoing RYGB. Secondary aims were to record complications and the resolution of comorbidities in a 2-year follow-up.

Methods

Of 722 patients with at least 2 years follow-up data, 48 elderly patients were matched with 92 young (<40 years) and 96 middle-aged (40–59 year) patients, according to sex, baseline body mass index, and date of surgery. Weight loss, remission of comorbidities, death, and early (30-day) and 2-year complication rates were compared.

Results

There were three deaths in the elderly group and none in the other groups. The early complication rate was not significantly different in the elderly group (17.8 %) compared with the young (11.5 %, p?=?0.637) and middle-aged (13.7 %, p?=?1.000) groups. The 2-year complication rates were not significantly different in the elderly group (9.3 %) compared with the young (23.5 %, p?=?0.107) and middle-aged (13.2 %, p?=?1.000) groups. The 2-year weight loss was lower in the elderly group (31.8?±?7.2 %; p?<?0.001) than in the young group (38.3?±?6.9 %) but was not significantly different from that in the middle-aged group (34.4?±?8.0 %; p?=?0.145). Remission rates for diabetes and obstructive sleep apnea were lower in the elderly than in the two younger groups.

Conclusion

After bariatric surgery, major weight loss was observed in patients older than 60, but remission of metabolic comorbidities was less marked than in younger subjects.

     

Comparison of surgical and conservative treatment outcomes for type a aortic dissection in elderly patients

Background

In recent years, surgical outcomes have improved, and positive reports on surgery for type A aortic dissection (AAD) in the elderly are increasing. However, the difference between surgical and conservative treatments in the elderly remains unclear. Therefore, we conducted this study to determine whether surgery should be performed for Stanford (AAD) in elderly patients.

Methods

Data of patients aged 80?years or older who were hospitalized for AAD from April 2014 to March 2016 were extracted from the Japanese national inpatient database. Outcome measures were all-cause in-hospital death, stroke, acute kidney injury and tracheotomy, and composite adverse events (consisting of all-cause in-hospital death, stroke, acute kidney injury, and tracheotomy), and we compared them between surgical and conservative treatments using propensity score matching.

Results

The study cohort included 3258 patients, with 845 matched pairs (1690 patients) in the propensity score matching. All-cause in-hospital death was significantly lower in the surgical treatment group than in the conservative treatment group before and after matching (15.6% vs. 51.1%, p?<?0.001; 16.7% vs. 31.6%, p?<?0.001, respectively); however, there was no significant difference in composite adverse events after matching (36.0%, conservative vs. 37.2%, surgical; p?=?0.65), and adjusted odds ratio was 1.06 and 95% confidence interval was 0.86–1.29 (p?=?0.61) with reference to conservative treatment.

Conclusions

All-cause in-hospital death among elderly patients with AAD was significantly lower in patients treated surgically than in those undergoing conservative treatment. However, there was no significant difference between the two groups in the event-free survival, which is important for the elderly. These findings may be used in the consideration of treatment course for elderly patients with AAD.

     

Post-recurrence survival of elderly patients 75 years of age or older with surgically resected non-small cell lung cancer

Purpose

The purpose of this study was to evaluate the outcomes of elderly patients 75 years of age or older with recurrent non-small cell lung cancer (NSCLC).

Methods

A total of 1237 consecutive patients with NSCLC underwent pulmonary resection at our institution. Of these patients, 280 experienced postoperative recurrence. The rate of the post-recurrence survival and predictors were analyzed independently in a group of younger patients (<75 years) and a group of elderly patients (≥75 years).

Results

There were 215 younger patients (<75 years) and 65 elderly (≥75 years) patients at the time of diagnosis of recurrence. The median post-recurrence survival time and the five-year survival rate of all cases were 25 months and 20.8 %, respectively. There were no significant survival differences between the younger and elderly groups (p = 0.20). A univariate analysis determined that gender, Eastern Cooperative Oncology Group performance status, smoking status, histological type and epithelial growth factor receptor (EGFR) mutation status were factors influencing the post-recurrence survival among the elderly patients. In addition, a multivariate analysis determined the EGFR mutation status to be an independent prognostic factor for the post-recurrence survival.

Conclusions

Elderly patients 75 years of age or older in this study achieved satisfactory long-term outcomes.

     

Bariatric Surgery in the Elderly Is Associated with Similar Surgical Risks and Significant Long-Term Health Benefits

Purpose

Older age (>?60) has been considered a relative contraindication for bariatric surgery due to increased complication risk. This study examined the risks and benefits of bariatric surgery for patients older than 60 years in Canadian population.

Methods

This was a retrospective cohort study of the Ontario Bariatric Registry: a database recording peri-operative and post-operative outcomes of publicly funded bariatric surgeries across the province. Patients who completed 1 year follow-up, who underwent laparoscopic gastric bypass (LRYGB) or laparoscopic sleeve gastrectomy (LSG) between January 2010 and May 2013, were divided into older (>?60) and younger (>?60) cohorts, and outcomes were compared.

Results

Between January 2010 and May 2013, 3166 registry patients underwent LRYGB or LSG and completed 1-year follow-up. Of these, 204 (6.5%) were older than 60 years, with 175 (85.8%) undergoing LRYGB and 29 (14.2%) LSG. Demographics were similar, except for a higher number of males in the older group (59 (28.9%) versus 452 (15.3%) (p?<?0.001)). No significant difference in complication rate was noted (15% for younger cohort versus 13.8% (p?=?0.889)). The average percentage of excess weight loss was significantly higher in the younger population (60.72% versus 56.25% (p?<?0.05)) overall, however not significantly in the LSG group. Reduction in medication use post-surgery for management of co-morbidities was significantly higher in the older patients (??0.91 versus ??2.03 (p?<?0.001)).

Conclusion

The older cohort who underwent LRYGB or LSG was at no greater risk for intra-operative and post-operative complications and showed greater reduction in medication use post-surgery when compared to the younger cohort.

     

Are suburethral slings less successful in the elderly?

Introduction and hypothesis

We aimed to evaluate the success of suburethral slings in women ≥70 years of age.

Methods

This was a retrospective cohort study of women who underwent suburethral sling placement. Subjects were separated into three groups: ≤50 years of age (group 1), 51 to 69 years of age (group 2), and ≥70 years of age (group 3). The primary aim was to evaluate success as defined by ≥ improved on a validated patient improvement satisfaction score and a negative postoperative standardized stress test.

Results

There were 1,464 subjects. Mean age was 44.51?±?4.25 (n?=?296) for group 1, 60.5?±?5.28 (n?=?680) for group 2, and 77.68?±?5.41 (n?=?488) for group 3. The median follow-up was 26 (6–498) weeks, 45 (6–498) weeks, and 42 (6–543) weeks, for groups 1, 2, and 3 respectively. Multiple logistic regression analysis demonstrated no difference in sling success according to age stratification. Lower success was associated with having had a previous sling (adjusted OR 0.25, 95 % CI 0.12–0.5), having detrusor overactivity (adjusted OR 0.44, 95 % CI 0.28–0.69), and having a history of urge urinary incontinence (UUI) for ≥ 4 years (adjusted OR 0.54, 95 % CI 0.31–0.95).

Conclusions

There is no difference in sling success between the elderly and younger populations. However, those with previous sling surgery or a long standing history of UUI may be at a higher risk of failure.

     

Minimally invasive repair of pectus carinatum: a retrospective analysis based on a single surgeon’s 10 years of experience

Objectives

Over the past decade, minimal invasive surgery for correction of pectus carinatum has gained worldwide acceptance. This study reviews our clinical experience with minimally invasive repair of pectus carinatum (MIRPC) since 2008.

Methods

Between 2008 and 2018, 101 patients (77 male, 24 female) underwent correction of pectus carinatum with the MIRPC technique. The mean age of the patients was 14.7?±?4.8 (3–38) years. Over an 8 years’ experience we slightly modified the original Abramson technique. All patients presented with cosmetic complaints and all had a flexible chest wall on “compression test”. Early follow-up was on postoperative day 15 and 30.

Results

The mean operative time was 42.1?±?16.9 min. The mean hospital stay was 4.2?±?0.9 days. Postoperative complications included pneumothorax (n?=?2, 1.9%), wound infection (n?=?2, 1.9%), skin perforation (n?=?2, 1.9%), intolerable pain (n?=?1, 0.9%), skin hyperpigmentation (n?=?1, 0.9%), and overcorrection (n?=?1, 0.9%). Initial postoperative results were excellent in all patients. The bars were removed at a median of 24.8?±?4.5 months in 44 of 101 patients. 43 of 44 (97.7%) patients whose bar were removed reported excellent results.

Conclusions

MIRPC is a feasible procedure with low morbidity and excellent cosmetic results in the treatment of pectus carinatum deformities in selected patients.

     

Risk factors for complications after diverting ileostomy closure in patients who have undergone rectal cancer surgery

Purpose

To clarify the risk factors for complications after diverting ileostomy closure in patients who have undergone rectal cancer surgery.

Methods

The study group comprised 240 patients who underwent a diverting ileostomy at the time of lower anterior resection or internal anal sphincter resection, in our department, between 2004 and 2015. Univariate and multivariate analyses of 18 variables were performed to establish which of these are risk factors for postoperative complications.

Results

The most common complications were intestinal obstruction and wound infection. Univariate analysis showed that an age of 72 years or older (p?=?0.0028), an interval between surgery and closure of 6 months or longer (p?=?0.0049), and an operation time of 145 min or longer (p?=?0.0293) were significant risk factors for postoperative complications. Multivariate analysis showed that age (odds ratio, 3.4236; p?=?0.0025), the interval between surgery and closure (odds ratio, 3.4780; p?=?0.0039), and operation time (odds 2.5179; p?=?0.0260) were independent risk factors.

Conclusions

Age, interval between surgery and closure, and operation time were independent risk factors for postoperative complications after diverting ileostomy closure. Thus, temporary ileostomy closure should be performed within 6 months after surgery for rectal cancer.

     

Oncologic and Perioperative Outcomes Following Selective Application of Laparoscopic Pancreaticoduodenectomy for Periampullary Malignancies

Background

Data are sparse regarding patient selection criteria or evaluating oncologic outcomes following laparoscopic pancreaticoduodenectomy (LPD). Having prospectively limited LPD to patients with resectable disease defined by National Comprehensive Cancer Network (NCCN) criteria, we evaluated perioperative and long-term oncologic outcomes of LPD compared to a similar cohort of open pancreaticoduodenectomy (OPD).

Methods

Consecutive patients (November 2010–February 2014) undergoing pancreaticoduodenectomy (PD) for periampullary adenocarcinoma were reviewed. Patients were excluded from further analysis for benign pathology, conversion to OPD for portal vein resection, and contraindications for LPD not related to their malignancy. Outcomes of patients undergoing LPD were analyzed in an intention-to-treat manner against a cohort of patients undergoing OPD.

Results

These selection criteria resulted in offering LPD to 77 % of all cancer patients. Compared to the OPD cohort, LPD was associated with significant reductions in wound infections (16 vs. 34 %; P?=?0.038), pancreatic fistula (17 vs. 36 %; P?=?0.032), and median hospital stay (9 vs. 12 days; P?=?0.025). Overall survival (OS) was not statistically different between patients undergoing LPD vs. OPD for periampullary adenocarcinoma (median OS 27.9 vs. 23.5 months; P?=?0.955) or pancreatic adenocarcinoma (N?=?28 vs. 22 patients; median OS 20.7 vs. 21.1 months; P?=?0.703).

Conclusions

The selective application of LPD for periampullary malignancies results in a high degree of eligibility as well as significant reductions in length of stay, wound infections, and pancreatic fistula. Overall survival after LPD is similar to OPD.

     

LBP rs2232618 polymorphism contributes to risk of sepsis after trauma

Background

Previous study revealed that rs2232618 polymorphism (Phe436Leu) within LBP gene is a functional variant and associated with susceptibility of sepsis in traumatic patients. Our aim was to confirm the reported association by enlarging the population sample size and perform a meta-analysis to find additional evidence.

Methods

Traumatic patients from Southwest (n?=?1296) and Southeast (n?=?445) of China were enrolled in our study. After genotyping, the relationship between rs2232618 and the risk of sepsis was analyzed. Furthermore, we proceeded with a comprehensive literature search and meta-analysis to determine whether the rs2232618 polymorphism conferred susceptibility to sepsis.

Results

Significance correlation was observed between rs2232618 and risk of sepsis in Southwest patients (P?=?0.002 for the dominant model, P?=?0.006 for the recessive model). The association was confirmed in Southeast cohort (P?=?0.005 for the dominant model) and overall combined cohorts (P =?4.5?×?10^?4, P?=?0.041 for the dominant and recessive model). Multiple logistical regression analyses suggested that rs2232618 polymorphism was related to higher risk of sepsis (OR?=?1.77, 95% CI?=?1.26–2.48, P?=?0.001 in Southwest patients; OR?=?2.11, 95% CI?=?1.24–3.58, P?=?0.006 in Southeast cohort; OR?=?1.54, 95% CI?=?1.34–2.08, P?=?0.006 in overall cohort). Furthermore, meta-analysis of four studies (including the present study) confirmed that rs2232618 within LBP increased the risk of sepsis (OR?=?1.75, P?<?0.001 for the dominant model; OR?=?6.08, P?=?0.003 for the recessive model; OR?=?2.72, P?<?0.001 for the allelic model).

Conclusions

The results from our replication study and meta-analysis provided firm evidence that rs2232618T allele significantly increased the risk of sepsis.

     

Treatment of stress urinary incontinence using polyacrylamide hydrogel in women after radiotherapy: 1-year follow-up

Introduction and hypothesis

Information on urethral bulking therapy in women after previous pelvic radiotherapy is lacking. This study compared the safety and efficacy of polyacrylamide intraurethral injections in patients with and without previous radiotherapy.

Methods

A total of 46 patients with severe stress urinary incontinence (SUI) were enrolled in this multicenter prospective trial. Group A consisted of 24 patients with previous radiotherapy to the pelvis for the treatment of a gynaecological malignancy. Group B consisted of 22 patients without previous radiotherapy. All patients were treated with a transurethral injection of a bulking solution (Bulkamid). The average follow-up was 12.4 months. The paired Wilcoxon test was used to compare the results before and after the procedure within the groups, and the two-sample Wilcoxon test was used for comparisons between groups.

Results

Complete continence was achieved in 25 % of patients in group A and in 36.4 % of patients in group B. Significantly reduced urine leakage was observed in both groups (p?=?0.0164 in group A and p?=?0.0002 in group B). The total scores in the International Consultation on Incontinence Questionnaire decreased by 5.2 in group A (p?=?0.0000) and 6.36 in group B (p?=?0.0001). The scores for the Total Patient Perception of Bladder Condition decreased by 1.54 in group A (p?=?0.0001) and 2.59 in group B (p?=?0.0000), with a significant difference between groups (p?=?0.0224). No clinically significant changes in urodynamic parameters were observed. No severe adverse events were noted.

Conclusions

Based on our results, we conclude that urethral bulking therapy is a valuable treatment option in patients with severe SUI who have undergone pelvic radiotherapy for the treatment of gynaecological malignancy.

     

Results of the treatment of first carpometacarpal joint osteoarthritis: trapeziectomy alone versus trapeziectomy associated with suspensionplasty

Backgrounds

The goal of this study was to compare trapeziectomy alone to trapeziectomy associated with a technique of suspensionplasty using the abductor pollicis longus with a minimum of 6 years of follow-up in the treatment of osteoarthritis of the first carpometacarpal joint.

Methods

Our series included 46 trapeziectomies in 35 patients, aged 69 years in average, among which 27 were women. In 27 cases group I, a trapeziectomy alone was performed, and in 19 cases group II, a trapeziectomy associated with an abductor pollicis longus suspensionplasty was performed.

Results

At the last follow-up, the difference between pre- and postoperative Quick DASH was ??36.104 in average in group I and ??38.877 in average in group II p?=?0.7717. The difference between pre- and postoperative pain was ??3.926 in average in group I and ??4.368 in average in group II p?=?0.35. The difference of pre- and postoperative thumb opposition was 0.630 in group I and 0.421 in group II p?=?0.3033. The average difference of pre- and postoperative key pinch was 0.389 in group I and 0.842 in group II p?=?0.3303. No complication was reported.

Conclusions

Our results suggest that it is unnecessary to perform a ligamentoplasty when a trapeziectomy is indicated.

     

Effect of twelve-month physical exercise program on patients with osteoporotic vertebral fractures: a randomized,controlled trial

Summary

We performed a randomized clinical trial to evaluate the effect of a 12-month physical exercise program on quality of life, balance, and functional mobility in postmenopausal women with osteoporotic vertebral fractures. All three outcomes improved in the intervention group and were better than in the controls.

Introduction

Th aim of this study was to evaluate the effectiveness of a structured physical exercise intervention on quality of life, functional mobility, and balance in patients with osteoporotic vertebral fractures and back pain.

Methods

Seventy-eight postmenopausal women with vertebral fractures were randomized into an exercise group (n?=?40) and a control group (n?=?38). The mean age was 69.2?±?7.7 years. All women had at least one osteoporotic vertebral fracture and suffered from chronic back pain. Patients with a history of vertebral and non-vertebral fracture within the past 6 months were excluded. The 40-min exercise program was conducted twice weekly for 1 year. Participants in the control group were instructed to continue their usual daily activities. Participants were assessed at baseline and at 12 months using the Quality of Life Questionnaire (QUALEFFO-41). Balance was measured with the Balance Master® System NeuroCom® and functional mobility was measured with the “timed up and go” test and “sit-to-stand” test.

Results

Total QUALEFFO-41 score after 12 months was significantly better in the exercise group (44.2?±?7.5) compared to the control group (56.6?±?9.4), p?<?0.0001. Quality of life improved in domains: “Pain”, “Physical function: Jobs around the house”, “Physical function: Mobility”, “Social function”, “General health perception” in the exercise group as compared to the control group. After 12 months, balance as assessed by “Tandem Walk and Sway” became significantly better in the exercise group as compared to the control group (p?=?0.02). A significant improvement in the “timed up and go” test (p?=?0.02) and the “sit-to-stand” test (p?=?0.01) was shown in the exercise group compared to the control group.

Conclusions

This is the first 12 month-randomized clinical trial of exercise in osteoporotic women with a vertebral fracture that demonstrates improvement of three key outcome measures: quality of life, functional mobility, and balance.

     

A Randomized,Double-Blind,Placebo-Controlled Trial of Intravenous Acetaminophen on Hospital Length of Stay in Obese Individuals Undergoing Sleeve Gastrectomy

Background

Retrospective studies indicate that acetaminophen iv administration reduces hospital length of stay (LoS) and opiate consumption in patients undergoing bariatric surgery.

Objective

This study sought to determine whether using acetaminophen iv in morbidly obese subjects undergoing sleeve gastrectomy decreased LoS and total hospital charges as compared to patients receiving saline placebo.

Setting

Single-center university hospital

Methods

Using a randomized, double-blind, placebo-controlled design, subjects were assigned to receive either acetaminophen iv (group A) or saline placebo iv (group P). Data were collected between Jan 1 and Dec 31, 2016. Group A received acetaminophen every 6 h for a total of four doses. The first dose was administered following the induction of general anesthesia; group P received saline iv on the same schedule. Anesthetic management and prophylactic antiemetic regimen were standardized in all subjects. Postoperative pain management consisted of hydromorphone via patient-controlled infusion pump. Primary outcomes include hospital LoS and associated hospital costs. Secondary outcomes include patient satisfaction and postoperative nausea and pain scores.

Results

Subject demographics (n?=?127) and intraoperative management were similar in the two groups. Across all subjects, median hospital LoS in group A (n?=?63) was 1.87 vs. 1.97 days in group P (n?=?64) (p?=?0.03, Wilcoxon rank-sum test). Postoperatively, daily quality-of-recovery (QoR-15) scores, narcotic consumption, and the use of rescue antiemetics were not significantly different between groups. Median hospital costs were as follows: group A, $12,885 vs. group P, $12,977 (n?=?64).

Conclusions

Acetaminophen iv may reduce hospital LoS in subjects undergoing sleeve gastrectomy.

     

Comparison of Vela and holmium laser enucleation of the prostate: a retrospective clinical trial with a 12-month follow-up

Purpose

This study aimed to estimate the validity and applicability of Vela laser enucleation of the prostate (VoLEP) in the management of benign prostatic hyperplasia (BPH).

Methods

A retrospective chart review of 112 patients with BPH who underwent VoLEP (n?=?60) or holmium laser enucleation of the prostate (HoLEP) (n?=?56) was conducted at our institution from January 2015 to June 2015. The general and perioperative characteristics of the patients were collected. The 12-month follow-up data, including the lower urinary tract symptom (LUTS) indexes (International Prostate Symptom Score [I-PSS], quality-of-life [QoL] score and maximum flow rate [Qmax]), as well as rates of perioperative and late complications, were analyzed.

Results

No significant differences were observed in pre- and perioperative parameters, including operation time (58.05?±?10.14 vs. 60.14?±?12.30 min, P?=?0.44), serum sodium decrease (3.49?±?0.83 vs. 3.48?±?0.84 mmol/L, P?=?0.97), hemoglobin decrease (1.28?±?0.38 vs. 1.24?±?0.77 g/dL, P?=?0.71), catheterization time (3.63?±?1.10 vs. 3.89?±?1.11 days, P?=?0.21) and hospital stay (4.57?±?1.25 vs. 4.68?±?1.18 days, P?=?0.63) between the two groups of patients. Compared with the HoLEP group, the noise during operation was lower in VoLEP group (47.22?±?10.31 vs. 59.45?±?9.65 db, P?<?0.05). During 1, 6 and 12 months of follow-up visits, the LUTS indexes (I-PSS, QoL score and Qmax) were remarkably improved in both groups when comparing with the baseline values. Furthermore, LUTS indexes were comparable in both groups (P?>?0.05).

Conclusion

Similarly as the holmium laser, the Vela laser is a potent, safe, efficient durable and surgical treatment option for minimally invasive surgery in patients with BPH-induced LUTS.

     

Impact of comorbidities on the postoperative outcomes of acute cholecystitis following early cholecystectomy

Purposes

The purpose of this study was to evaluate the influence of comorbidities on the surgical outcomes of early cholecystectomy for acute cholecystitis.

Methods

Data were retrospectively collected for patients with acute cholecystitis who underwent early cholecystectomy. Patients were separated into three groups based on the cholecystitis severity grade, and the surgical outcomes of early cholecystectomy were analyzed. Patients with mild and moderate cholecystitis were subdivided into a comorbidity group (n?=?10) and a non-comorbidity group (n?=?83).

Results

There were 57 (55.3%) patients with mild cholecystitis, 36 (35.0%) with moderate cholecystitis, and 10 (9.7%) with severe cholecystitis. The surgical outcomes were significantly worse for patients with severe cholecystitis than for patients with mild or moderate cholecystitis. There were no postoperative deaths after cholecystectomy. There were no significant differences in the complication rate (P?=?0.629), conversion rate (P?=?0.114), or intraoperative blood loss (P?=?0.147) between the comorbidity and non-comorbidity groups.

Conclusion

Our findings suggest that early cholecystectomy can be performed safely for patients with mild and moderate cholecystitis even if comorbidities are present. Early cholecystectomy may be an alternative treatment strategy for patients with severe cholecystitis who are candidates for anesthesia and surgery.

     

FGF 19 and Bile Acids Increase Following Roux-en-Y Gastric Bypass but Not After Medical Management in Patients with Type 2 Diabetes

Background

This study aims to quantify changes in fibroblast growth factor 19 (FGF19) and bile acids (BAs) in patients with uncontrolled type 2 diabetes randomized to Roux-en-Y gastric bypass (RYGB) vs intensive medical management (IMM) and matched for similar reduction in HbA1c after 1 year of treatment.

Methods

Blood samples were drawn from patients who underwent a test meal challenge before and 1 year after IMM (n?=?15) or RYGB (n?=?15).

Results

Mean HbA1c decreased from 9.7 to 6.4 % after RYGB and from 9.1 to 6.1 % in the IMM group. At 12 months, the number of diabetes medications used per subject in the RYGB group (2.5?±?0.5) was less than in the IMM group (4.6?±?0.3). After RYGB, FGF19 increased in the fasted (93?±?15 to 152?±?19 pg/ml; P?=?0.008) and postprandial states (area under the curve (AUC), 10.8?±?1.9 to 23.4?±?4.1 pg?×?h/ml?×?10³; P?=?0.006) but remained unchanged following IMM. BAs increased after RYGB (AUC ×10³, 6.63?±?1.3 to 15.16?±?2.56 μM?×?h; P?=?0.003) and decreased after IMM (AUC ×10³, 8.22?±?1.24 to 5.70?±?0.70; P?=?0.01). No changes were observed in the ratio of 12α-hydroxylated/non-12α-hyroxylated BAs. Following RYGB, FGF19 AUC correlated with BAs (r?=?0.54, P?=?0.04) and trended negatively with HbA1c (r?=??0.44; P?=?0.09); these associations were not observed after IMM.

Conclusions

BA and FGF19 levels increased after RYGB but not after IMM in subjects who achieved similar improvement in glycemic control. Further studies are necessary to determine whether these hormonal changes facilitate improved glucose homeostasis.

     

A Pre-Hospital Patient Education Program Improves Outcomes of Bariatric Surgery

Background

We designed an assessment and education program which was delivered to patients prior to first outpatient appointment for bariatric surgery. We hypothesised that this program would streamline care and would lead to improved weight loss following bariatric surgery.

Methods

The program incorporates a structured general practitioners (GP) review, a patient information evening and an on-line learning package. It was introduced in September 2012. Patient flow through the program was recorded. Outcomes of the new program were compared with contemporaneously treated patients who did not undertake the pre-hospital program.

Results

All 636 patients on the waiting list for first appointment at the Alfred Health bariatric surgery clinic were invited to participate. There were 400 patients ultimately removed from the waiting list for first appointment. Of the remaining 236 patients, 229 consented to participate in the new program. The mean BMI was 47.8?±?9.2. The fail to attend first appointment rate dropped from 12 to 2.1 %. At 12 months post-bariatric surgery, patients who undertook the new program (n?=?82) had a mean excess weight loss (EWL) of 41.1?±?20.3 % where as those treated on the standard pathway (n?=?61) had a mean EWL 32?±?18.0 % (p?=?0.012).

Conclusions

The introduction of a pre-hospital education program has led to an improvement in attendance rates and early weight loss post-bariatric surgery.

     

Predictors of disease-specific quality of life after arthroscopic rotator cuff repair

Purpose

Disease-specific instruments of quality of life (QOL) are more sensitive to disease-specific changes. The purpose of this study is to identify prognostic factors for disease-specific QOL after all-arthroscopic rotator cuff (RC) repair using the Western Ontario Rotator Cuff Index (WORC).

Methods

A total of 140 patients were evaluated after an RC repair with a mean follow-up of 22?±?6.7 months. Evaluations included the WORC, EQ-5D and anchor questions. Preoperative patient demographics and radiologic characteristics were assessed to identify predictors of disease-specific QOL.

Results

Most patients (81.4 %) were satisfied with their surgical result. Minor tear retraction (odds ratio [OR] 2.97, p?=?0.030), male gender (OR 3.67, p?=?0.003), no social benefits (OR 3.67, p?=?0.042) and pre-surgical complaints for more than six months (OR 3.03, p?=?0.021) were independent predictors for superior postoperative WORC score in multivariable analysis. None of these factors were predictive for a higher EQ-5D score.

Conclusion

These findings highlight the important impact of retraction on QOL after RC repair and underline the utility of disease-specific instruments. Future studies should focus on how these significant predictors can be used to improve decision making and to develop new treatment approaches.

     

Midterm follow-up of a randomized trial of open surgery versus laparoscopic surgery in elderly patients with colorectal cancer

Background

Laparoscopic surgery has been widely accepted for the treatment of colorectal cancer; however, long-term outcomes in elderly patients remain controversial. The midterm results of a randomized trial comparing open surgery with laparoscopic surgery in elderly patients with colorectal cancer are presented.

Methods

This was a randomized trial comparing open surgery with laparoscopic surgery in elderly patients with colorectal cancer. The primary outcome was complication rate, and secondary outcomes included 3-year recurrence-free survival and overall survival. A total of 200 patients were randomly assigned to open surgery or laparoscopic surgery between 2008 and 2012. The main study objective was to compare the midterm outcomes of open surgery with those of laparoscopic surgery in elderly patients with colorectal cancer. This trial is registered with Clinical Trials.gov (NCT01862562).

Results

There were no differences between the laparoscopic surgery group and open surgery group in the 3-year overall survival rate (91.5% for laparoscopic surgery vs. 90.6% for open surgery, p?=?0.638) or the 3-year recurrence-free survival rate (84.8% for laparoscopic surgery vs. 88.2% for open surgery, p?=?0.324). The local recurrence rate was significantly higher in the laparoscopic surgery group than in the open surgery group in rectal cancer (13.8% for laparoscopic surgery vs. 0% for open surgery, p?=?0.038). In subgroup analysis according to tumor location, there were no significant differences in the 3-year overall survival rate or 3-year recurrence-free survival rate between the two treatment groups.

Conclusion

The midterm outcomes of laparoscopic surgery are similar to those of open surgery in elderly patients with colorectal cancer.
