Introduction
Anastomotic complications after esophagectomy are relatively frequent. The off-label use of self-expanding covered metal stents has been shown to be an effective initial treatment for leaks, but there is a paucity of literature regarding their use in cervical esophagogastric anastomoses. We reviewed our outcomes with anastomotic stenting after esophagectomy with cervical esophagogastric reconstruction.Methods
All stents placed across cervical anastomoses following esophagectomy from 2004 to 2014 were retrospectively reviewed. Indications for surgery and stent placement were collected. For patients with serial stents, each stent event was evaluated separately and as part of its series. Success was defined as resolution of indicated anastomotic problem for at least 90 days. Complications were defined as development of stent-related problems.Results
Twenty-three patients had a total of 63 stents placed (16 % prophylactic, 38 % leak, 46 % stricture). Sixty percent of patients had successful resolution of their initial anastomotic problem; 67 % required more than one stent. Strictures and leaks healed in 27 and 70 % of patients, respectively, at a median of 55.5 days. Stent-related complications occurred in 78 % of patients. Complications (per stent event) included 62 % migration, 11 % clinically significant tissue overgrowth, 8 % minor erosion (ulcers), and 8 % major erosion. Stents placed for stricture were more likely to result in complications, especially migration (76.7 vs. 48.5 %, p = 0.02). Preoperative chemoradiation was a significant risk factor for erosion (22.5 vs. 4.3 %, p = 0.05), but not for overall complications. Patients with major erosions had longer stent duration compared to those without (92 vs. 36 days, p = 0.14).Discussion
Although stents are effective at controlling post-esophagectomy anastomotic leaks, they are not effective for treating strictures. Stents have high complication rates, but most are minor. Chemoradiation is a risk factor for stent erosion. Caution should be used when stent duration exceeds 2–3 months due to the risk of erosion.2.

Background
Evidence suggests externalized trans-anastomotic stents may be beneficial as a fistula mitigation strategy for pancreatoduodenectomy (PD); however, previous studies have not been rigorously risk-adjusted.Methods
From 2001 to 2015, PDs were performed at three institutions, with externalized stents placed at the surgeon’s discretion. The Fistula Risk Score (FRS) and the Modified Accordion Severity Grading System were used to analyze occurrence and severity of clinically relevant postoperative pancreatic fistula (CR-POPF) across various risk scenarios.Results
Of 729 PDs, externalized stents were placed during 129 (17.7 %). Overall, CR-POPFs occurred in 77 (10.6 %) patients. The median FRS of patients who received externalized stents was significantly higher compared with patients who did not (6 vs. 3, p?<?0.0001). Patients with negligible, low, or moderate CR-POPF risk (FRS 0–6) did not demonstrate improved outcomes with externalized stents; however, among high-risk patients (FRS 7–10), stents were associated with significantly reduced rates of CR-POPF (14.0 vs. 36.4 %, p?=?0.031), severe complications (p?=?0.039), and hospital stay (p?=?0.014) compared with no stents. The average complication burden of CR-POPF was significantly lower for patients with externalized stents (p?=?0.035).Conclusion
This multicenter study, the largest comparative analysis of externalized trans-anastomotic stents versus no stent for PD, demonstrates a risk-stratified benefit to externalized stents.3.
Background
There is no consensus opinion on a definitive surgical management option for ranulas to curtail recurrence, largely from the existing gap in knowledge on the pathophysiologic basis.Aim
To highlight the current scientific basis of ranula development that informed the preferred surgical approach.Design
Retrospective cohort study.Setting
Public Tertiary Academic Health Institution.Method
A 7-year 7-month study of ranulas surgically managed at our tertiary health institution was undertaken—June 1, 2008–December 31, 2015—from case files retrieved utilising the ICD-10 version 10 standard codes.Results
Twelve cases, representing 0.4 and 1.2% of all institutional and ENT operations, respectively, were managed for ranulas with a M:F = 1:1. The ages ranged from 5/12 to 39 years, mean = 18.5 years, and the disease was prevalent in the third decade of life. Main presentation in the under-fives was related to airway and feeding compromise, while in adults, cosmetic facial appearance. Ranulas in adults were plunging (n = 8, 58.3%), left-sided save one with M:F = 2:1. All were unilateral with R:L = 1:2. Treatment included aspiration (n = 2, 16.7%) with 100% recurrence, intra-/extraoral excision of ranula only (n = 4, 33.3%) with recurrence rate of 50% (n = 2, 16.7%), while marsupialisation in children (n = 1, 8.3%) had no recurrence. Similarly, transcervical approach (n = 5, 41.7%) with excision of both the ranula/sublingual salivary gland recorded zero recurrence. Recurrence was the main complication (n = 4, 33.3%).Conclusion
With the current knowledge on the pathophysiologic basis, extirpation of both the sublingual salivary gland and the ranula by a specialist surgeon is key for a successful outcome.4.

Background
The multidiameter balloon catheter is used widely for severe esophageal stricture dilation. However, the relationships between inflation pressure, balloon size, and radial dilation force at the stricture site have not been examined fully.Methods
We performed an experiment using phantom models to investigate the relationships between inflation pressure, balloon size, and radial dilation force. The balloon dilation procedure was performed for each stricture model using three sizes of balloon: 10–11–12, 12–13.5–15, and 15–16.5–18 mm.Results
A positive association between inflation pressure and dilation force was observed for each balloon size. In balloons inflated by targeting the same diameter, the dilation force was higher for smaller balloons than for larger balloons. An inverse association between stricture size and dilation force was observed in the 12–13.5–15 mm balloon (3 vs 5 mm, P = .002; 5 vs 7 mm, P < .001).Conclusions
We found relationships between inflation pressure, balloon size, severity of strictures, and dilation force. To perform safe and effective esophageal balloon dilation, the inflation pressure and balloon size should be selected after considering the stricture size and target diameter.5.

Background
Patient-reported outcomes require validation in a particular language and culture before administration for clinical use.Materials and methods
A systematic translation of the IKDC Subjective Knee Form was initially tested in 30 patients with various knee pathologies to develop the first Greek version (IKDC/SKF-GR). It was then administered to another 80 patients. The test–retest reliability (n = 35) and internal consistency (n = 80) were examined. Construct validity was tested by correlating the IKDC/SKF-GR with the SF-36 subscales (n = 80) and content validity by measuring floor/ceiling effects. Responsiveness was measured in patients with meniscus pathology (n = 24).Results
Patients filled the form without omissions/questions regarding the phrasing of items. Internal consistency was good (Cronbach’s α = 0.87) and test–retest reliability very good (ICC2,1 = 0.95, SEM = 4.4 and SDC = 12.2). Correlations with the SF-36 subscales confirmed its construct validity. No floor/ceiling effects were recorded. The effect size was large (ES = 1.26).Conclusions
The IKDC/SKF-GR has comparable measurement properties to the original form.Level of evidence

Purpose
Ureteral stenting is associated with various morbidity and reduced quality of life. We systematically evaluated the efficacy and safety of solifenacin as monotherapy, or combined therapy with tamsulosin versus control or tamsulosin monotherapy in stent-related symptoms (SRSs).Materials and methods
Randomized controlled trials evaluating solifenacin or its combination with tamsulosin for the treatment of SRSs were identified via a comprehensive search of Pubmed, Embase, Ovid, The Cochrane Library and relevant sources up to February 2017. Ureteral stent symptom questionnaire (USSQ) and drug-related complications were pooled for meta-analysis. Mean difference and risk difference were calculated as appropriate for each outcome to determine the cumulative effect size.Results
There were 10 studies involving 1786 participants finally eligible in the quantitative analysis. Solifenacin monotherapy significantly reduced the total score of USSQ [MD ?14.90; 95% CI (?25.19, ?4.60); P = 0.005], as well as indexes of urinary symptoms, body pain, general health, sexual performance, and hematuria (P = 0.02, P = 0.009, P = 0.004, P = 0.02, P = 0.02, respectively), but the differences were insignificant when compared with tamsulosin except improved sexual performance (P = 0.004). Combined therapy of solifenacin and tamsulosin showed no beneficial effects in all indexes of USSQ over solifenacin monotherapy. Only slightly higher incidence of dry mouth (P = 0.02) was found with solifenacin versus control.Conclusions
The result demonstrates the safety and efficacy of solifenacin in reducing SRSs, but no significant advantage was found over tamsulosin. In addition, combination of solifenacin and tamsulosin did not show beneficial effects over solifenacin monotherapy. More high quality trials are warranted to further address this issue, however.7.
Purpose
To investigate the outcomes of patients with colorectal cancer and initially unresectable or not optimally resectable liver metastases, who were treated using the liver-first approach in the era of modern chemotherapy in Japan.Methods
We analyzed and compared data retrospectively on patients with asymptomatic resectable colorectal cancer and initially unresectable or not optimally resectable liver metastases, who were treated either using the liver-first approach (n = 12, LF group) or the primary-first approach (n = 13, PF group).Results
Both groups of patients completed their therapeutic plan and there was no mortality. Postoperative morbidity rates after primary resection and hepatectomy, and post-hepatectomy liver failure rate were comparable between the groups (p = 1.00, p = 0.91, and p = 0.55, respectively). Recurrence rates, median recurrence-free survival since the last operation, and 3-year overall survival rates from diagnosis were also comparable between the LF and PF groups (58.3 vs. 61.5 %, p = 0.87; 10.5 vs. 18.6 months, p = 0.57; and 87.5 vs. 82.5 %, p = 0.46, respectively).Conclusions
The liver-first approach may be an appropriate treatment sequence without adversely affecting perioperative or survival outcomes for selected patients.8.

Purpose
To compare the effectiveness of tamsulosin and solifenacin in relieving ureteral stents related symptoms.Patients and methods
A randomized controlled trial was conducted between January 2013 and July 2014. Inclusion criteria were patients aged 20–50 years who underwent temporary unilateral ureteral stent for drainage of calcular upper tract obstruction or after ureteroscopic lithotripsy. Patients with history of lower urinary tract symptoms before stent placement, stents that were fixed after open or laparoscopic procedures, and those who developed complications related to the primary procedure were not included. Eligible patients were randomly assigned to 1 of 3 groups using computer-generated random tables. Patients in group 1 received placebo, patients in group 2 received tamsulosin 0.4 mg once daily, and those in group 3 received solifenacin 5 mg once daily. Ureteral Stent Symptom Questionnaire (USSQ) was answered by all patients 1–2 weeks after stent placement. The primary outcome was the comparison of total score of USSQ between all groups.Results
The study included 131 patients. All baseline characteristics (age, sex, side, indication, length, and duration of stent) were comparable for all groups. Total USSQ score was 61 in solifenacin group, 76 in tamsulosin group, and 83 in control group (P < 0.001). The total USSQ scores and all domains, except sexual index, were significantly better in solifenacin than in tamsulosin group (P < 0.05).Conclusion
The use of tamsulosin alone or solifenacin alone in patients with ureteral stents can improve the quality of life by decreasing ureteral stent-related symptoms. Solifenacin was better than tamsulosin.ClinicalTrial.gov Identifier

Objectives
There is increasing evidence that Glasgow Prognostic Score (GPS), based on systemic inflammatory response and albumin level, is a useful predictor of overall survival in patients with various types of cancer.Methods
Patients with lung metastasis from colorectal carcinoma who underwent a lung metastasectomy from 2000 to 2015 were retrospectively investigated. Routine laboratory measurements including serum C-reactive protein (CRP), albumin, and the tumor marker carcinoembryonic antigen were performed before the metastasectomy.Results
Ninety-nine patients underwent 132 lung metastasectomy procedures during the study period. Kaplan–Meier analysis revealed that GPS (p = 0.017), number of metastases (p = 0.004), and the presence of liver metastasis (p = 0.010) were associated with overall survival, while univariate analysis selected GPS (p = 0.028), number of metastases (p = 0.005), and liver metastasis (p = 0.014) as predictive factors associated with overall survival. Multivariate analysis also indicated GPS (p = 0.004), number of metastases (p = 0.004), and liver metastasis (p = 0.013) as predictive factors associated with overall survival.Conclusion
In addition to number of metastases and liver metastasis, GPS is an important predictor of overall survival in colorectal cancer patients who undergo a lung metastasectomy.10.
Purpose
To compare the clinical and radiographic outcomes of arthrodesis in situ with arthrodesis after reduction in low-grade spondylolisthesis.Methods
We performed a comprehensive search of both observational and randomized clinical trials published up to April 2016 in PubMed, MEDLINE, Cochrane Library, and Embase databases. The outcomes included age, sex, operative time, blood loss, and at least 2 years clinical results of Oswestry disability index (ODI), visual analogue scale (VAS), lumbar lordosis, slippage, fusion rate, the rate of good and excellent and the complication rate. Two authors independently extracted the articles and the predefined data.Results
Seven eligible studies, involving four RCTs and three cohort studies were included in this systematic review and meta-analysis. Patients who underwent reduction did achieved better slippage correction comparing with arthrodesis in situ (P < 0.00001). However, there was no significant difference in the case of operative time, blood loss, VAS (P = 0.36), ODI (P = 0.50), lumbar lordosis (P = 0.47), the rate of good and excellent (P = 0.84), fusion rate (P = 0.083) and complication rate (P = 0.33) between the arthrodesis in situ group and the reduction group.Conclusions
On the basis on this review, arthrodesis after reduction of low-grade spondylolisthesis potentially reduced vertebral slippage. Reduction was neither associated with a longer operative time nor more blood loss. There was no significant difference in the outcomes between reduction and arthrodesis in situ group. Both procedures could be expected to achieve good clinical result.Level of evidence

Background and aims
Delayed gastric emptying after esophagectomy with gastric replacement can pose a significant postoperative problem, often leading to aspiration and pneumonia. The present study analyzes retrospectively the effectiveness of endoscopic pyloric dilatation for post-surgical gastric outlet obstruction.Methods
Between March 2006 and March 2010, 403 patients underwent a transthoracic en-bloc esophagectomy and reconstruction with a gastric tube and intrathoracic esophagogastrostomy. In patients with postoperative symptoms of an outlet dysfunction and the confirmation by endoscopy, pyloric dilatations were performed without preference with either 20- or 30-mm balloons.Results
A total of 89 balloon dilatations of the pylorus after esophagectomy were performed in 60 (15.6 %) patients. In 21 (35 %) patients, a second dilatation of the pylorus was performed. 55 (61.8 %) dilatations were performed with a 30-mm balloon and 34 (38.2 %) with a 20-mm balloon. The total redilatation rate for the 30-mm balloon was 20 % (n = 11) and 52.9 % (n = 18) for the 20-mm balloon (p < 0.001). All dilatations were performed without any complications.Conclusions
Pylorus spasm contributes to delayed gastric emptying leading to postoperative complications after esophagectomy. Endoscopic pyloric dilatation after esophagectomy is a safe procedure for treatment of gastric outlet obstruction. The use of a 30-mm balloon has the same safety profile but a 2.5 lower redilatation rate compared to the 20-mm balloon. Thus, the use of 20-mm balloons has been abandoned in our clinic.12.
Purpose
The aim of this study is to explore the role of attachment styles in obesity.Material and Methods
The present study explored differences in insecure attachment styles between an obese sample waiting for bariatric surgery (n = 195) and an age, sex and height matched normal weight control group (n = 195). It then explored the role of attachment styles in predicting change in BMI 1 year post bariatric surgery (n = 143).Results
The bariatric group reported significantly higher levels of anxious attachment and lower levels of avoidant attachment than the control non-obese group. Baseline attachment styles did not, however, predict change in BMI post surgery.Conclusion
Attachment style is different in those that are already obese from those who are not. Attachment was not related to weight loss post surgery.13.

Purpose
The optimal analgesia following laparoscopic distal gastrectomy (LDG) has not been determined; moreover, it has been unclear whether epidural anesthesia has benefits for laparoscopic surgery. In this study, we evaluated the effectiveness of epidural analgesia after LDG.Methods
This retrospective study included 84 patients who underwent LDG for gastric cancer. Patients received either combined thoracic epidural and general anesthesia (Epidural group, n = 34) or general anesthesia alone (No epidural group, n = 50). We recorded data on the patients, surgery, postoperative outcomes and anesthesia-related complications.Results
In the Epidural group, the first day of flatus was significantly earlier (2.21 vs. 2.44 days, p = 0.045) and the number of additional doses of analgesics was significantly lower (2.85 vs. 4.86 doses, p = 0.007) than in the No epidural group. Postoperative urinary retention occurred at a significantly higher rate in the Epidural group (n = 7; 20.6 %) than in the No epidural group (p < 0.001).Conclusion
Epidural anesthesia may reduce the need for additional analgesics after LDG, but increases the risk of urinary retention.14.

Background
Epidemiological studies show that 5–40 % of type 2 diabetes (T2DM) patients have diabetic nephropathy, and oxidative stress is one of several underlying mechanisms. We investigated associations between oxidative stress markers and severity of diabetic nephropathy.Methods
Fifty-nine T2DM patients from the endocrinology outpatient department were included, and their levels of oxidative stress markers were measured. Three groups were determined by their urine albumin-to-creatinine ratio (UACR): group A (UACR < 30 mg/g, n = 22); group B (30 ≤ UACR < 300 mg/g, n = 22); and group C (UACR ≥ 300 mg/g, n = 15).Results
Vitamin C levels correlated negatively and moderately with serum creatinine (γ = ?0.459, p < 0.001), urine albumin (γ s = ?0.458, p = 0.001) and UACR (γ s = ?0.408, p = 0.001), but only weakly with hydroxy-2-deoxyguanosine (8-OHdG) and estimated glomerular filtration rate (eGFR). Vitamin C levels decreased as 8-OHdG, serum creatinine, albumin and UACR increased. T2DM patients with more severe diabetic nephropathy had lower vitamin C levels.Conclusion
Our results identified several oxidative stress markers that may be clinically important in diabetic nephropathy. Studies with larger sample sizes should be undertaken to confirm these findings.16.
Purpose
We developed a novel vaporization–enucleation technique (Seoul II), which consists of vaporization–enucleation of the prostate using 120-W HPS GreenLight laser, and enucleated prostate resection using bipolar devices for tissue removal. We compared the outcomes of the Seoul II with vaporization and a previously reported modified vaporization–resection technique (Seoul I).Methods
Among patients with benign prostate hyperplasia who underwent transurethral surgery using GreenLight laser at our institute, 347 patients with prostate volume ≥ 40 ml were included. The impact of surgical techniques on efficacy and postoperative functional outcomes was compared.Results
No difference was found in baseline characteristics, although the prostate volume was marginally greater in Seoul II (p = 0.051). Prostate volume reduction per operation time (p < 0.001) and lasing time (p = 0.016) were greater in Seoul II. At postoperative 12 months, the International Prostate Symptom Score (I-PSS) was lower (p = 0.011), and the decrement in I-PSS was greater in Seoul II (p = 0.001) than other techniques. In multivariate analysis, postoperative 12-month I-PSS for Seoul II was significantly superior to vaporization (p < 0.001), although it was similar to Seoul I. The maintenance of immediate postoperative I-PSS decrement, until postoperative 12 months was superior in Seoul II compared with vaporization (p = 0.014) and Seoul I (p = 0.048).Conclusions
Seoul II showed improved efficacy and voiding functional maintenance over postoperative 12 months in patients with prostate volume ≥ 40 ml compared with vaporization and Seoul I. This technique could be easily accepted by clinicians who are familiar with GreenLight lasers and add flexibility to surgery without additional equipment.17.

Background and objectives
Hepatic resection is established as the treatment for HCC. However, patients sometimes experience early recurrence of HCC (ER HCC) after curative resection.Methods
A retrospective analysis was conducted for 193 patients with single HCC who underwent curative liver resection in our medical center between April 2000 and March 2013. We divided the cohort into two groups; early recurrence group (ER G) which experienced recurrence within 6 months after resection, and non-early recurrence group (NER G). Risk factors for ER HCC were analyzed.Results
Thirty-nine out of 193 (20.2 %) patients had ER HCC. Univariate analysis showed Glasgow prognostic score (GPS, p = 0.036), neutrophil to lymphocyte ratio (NLR, p = 0.001), level of PIVKA-II (p = 0.0001), level of AFP (p = 0.0001), amounts of blood loss (p = 0.001), operating time (p = 0.002), tumor size (p = 0.0001), stage III and IV (p = 0.0001), and microvascular invasions (portal vein: p = 0.0001 and hepatic vein: p = 0.001) to be associated with ER HCC. By multivariate analysis, there were significant differences in high NLR (p = 0.029) and high AFP (p = 0.0001) in patients with ER HCC.Conclusions
Preoperative high AFP (more than 250 ng/ml) and high NLR (more than 1.829) were independent risk factors for ER HCC.18.

Objectives
The aim of this study is to evaluate the effect of massive weight loss on the seminal parameters at 6 months from bariatric surgery.Design
Two-armed prospective study performed in 31 morbidly obese men, undergoing laparoscopic roux-en-Y-gastric bypass (n = 23) or non-operated (n = 8), assessing sex hormones, conventional (sperm motility, morphology, number, semen volume), and non-conventional (DNA fragmentation and seminal interleukin-8), semen parameters, at baseline and after 6 months from surgery or patients’ recruitment.Results
In operated patients only, a statistically significant improvement in the sex hormones was confirmed. Similarly, a positive trend in the progressive/total sperm motility and number was observed, though only the increase in semen volume and viability was statistically significant (Δ = 0.6 ml and 10%, P < 0.05, respectively). A decrease in the seminal interleukin-8 levels and in the sperm DNA fragmentation was also present after bariatric surgery, whereas these parameters even increased in non-operated subjects. Age-adjusted multivariate analysis showed that the BMI variations significantly correlated with the changes in the sperm morphology (β = ?0.675, P = 0.025), sperm number (β = 0.891, P = 0.000), and semen volume (r = 0.618, P = 0.015).Conclusion
The massive weight loss obtained with bariatric surgery was associated with an improvement in some semen parameters. The correlations found between weight loss and semen parameter variations after surgery suggest that these might occur early downstream of the testis and more slowly than the changes in the sex hormones.19.

Background
In patients with unresectable colorectal cancer (CRC) obstruction, choosing whether to perform self-expandable metal stent (SEMS) or palliative surgery is challenging, especially in those with good performance status. We aimed to compare the long-term outcomes of SEMS with those of palliative surgery in patients with unresectable CRC obstruction.Methods
This retrospective study comprised 114 patients with unresectable CRC obstruction who underwent SEMS placement (n = 73) or palliative surgery (n = 41). The main outcome measurements were success rate, adverse events, patency, and survival duration.Results
Early clinical success rates did not differ between SEMS and surgery. However, the rate of late adverse events was significantly higher in the SEMS group (27.4 vs. 9.8 %; P = .005). Patency duration was shorter after SEMS than after surgery (163 vs. 349 days; P < .001), even after additional intervention (202 vs. 349 days; P < .001). The median survival was significantly shorter after SEMS than after surgery (209 vs. 349 days; P = .005). Survival differed between treatments in patients with Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1 (P = .016) but not in those with ECOG 2 or 3 (P = .487), and this was confirmed by multivariate analysis, which showed that surgery was a significant favorable predictor of survival for patients with ECOG 0 or 1 (hazard ratio .442; 95 % confidence interval .234–.835; P = .016).Conclusions
Surgery may be preferable to SEMS for the palliation of unresectable CRC obstruction in patients with good performance status, especially ECOG 0 or 1.20.
