Abstract
BACKGROUND There is no consensus on pain control in patients undergoing laparoscopy; nowadays, conventional therapy may be improved by transversus abdominis plane block. The aim of this evaluation is to investigate the role of laparoscopic-assisted trocar-site ropivacaine infiltration during adrenalectomy in pain control. METHODS This is a retrospective evaluation of a prospectively maintained database including patients undergoing adrenalectomy. Patients were divided into 2 groups: Group A patients received laparoscopic-assisted trocar-site infiltration of 7.5 mg/mL ropivacaine and Group B patients did not receive any infiltration. All patients received a 24-hour infusion of 20 mg morphine; pain was checked at 6, 24, and 48 hours after surgery by Visual Analogue Scale (VAS) score. A rescue analgesia by was given if VAS score was > 4 or on patient request. RESULTS No differences in operative time, complications, and post-operative stay and no complications related to trocar-site infiltration were found. 6-hour and 48-hour VAS scores were not found to be significantly different between groups, even if a slight decrease in VAS score in Group A was reported. Group A showed significant reduction in VAS score at 24 hours (2.44 +/- .41 vs 3.01 +/- .78, P < .005) and in the number of patients requiring further analgesic drugs administration (40.6% vs 57.8%, P < .005). CONCLUSIONS Laparoscopic-guided trocar-site ropivacaine infiltration can be considered safe and effective in the management of post-operative pain and in the reduction of analgesic need in patients undergoing laparoscopic adrenalectomy. The retrospective nature of the study and the lack of a consistent series of patients require further evaluations.

Abstract
Objective. The total relative value unit (TRVU) of surgery reflects surgical complexity. However, its impact on mortality after noncardiac surgery has not been identified. This study aimed to investigate the association of TRVUs for surgery with postoperative 90-day mortality in adult patients who received planned, elective noncardiac surgery. We hypothesized that higher TRVU was associated with an increase in 90-day mortality after noncardiac surgery. Method. This retrospective cohort study analyzed medical records of adult patients admitted to a single tertiary academic hospital between January 2012 and December 2018 for planned elective noncardiac surgery. The primary end point was 90-day mortality. Results. A total of 112 606 patients were included. Among them, 561 patients (.5%) exhibited mortality within 90-days. In the multivariable model, an increase of 10 000 points of TRVUs was not significantly associated with 90-day mortality (odds ratio: .98, 95% confidence interval: .93 to 1.04; P = .536). Additionally, when it was divided into 4 quartile groups (Q1, Q2, Q3, and Q4), Q2, Q3, and Q4 group of TRVUs were not associated with 90-day mortality compared to the Q1 group of TRVUs (P = .058, .984, and .237, respectively). In receiver-operating characteristic analysis, the area under the curve of TRVUs for a 90-day mortality rate was .61. Conclusions. In conclusion, TRVUs were not associated significantly with a 90-day mortality rate after noncardiac surgery and have a low predictive ability for 90-day mortality after noncardiac surgery alone.

Abstract
Background. Laparoscopic cholecystectomy (LC) often results in postoperative pain, especially in the abdomen. Intraperitoneal local anesthesia (IPLA) reduces pain after LC. Acute cholecystitis-associated inflammation, increased gallbladder wall thickness, dissection difficulties, and a longer operative time are several reasons for assuming a benefit in pain scores in urgent LC with IPLA application. The aim was to determine the postoperative analgesic efficacy of high-volume, low-dose intraperitoneal bupivacaine in urgent LC. Materials and Methods. Fifty-seven patients who were American Society of Anesthesiologists physical status I or II were randomly assigned to receive either normal saline (control group) or intraperitoneal bupivacaine (test group) at the beginning or end of urgent LC. The primary outcome was the postoperative pain score of the Visual Analogue Scale (VAS). The secondary outcomes included Visual Rating Prince Henry Scale (VRS), patient satisfaction, and analgesic consumption. Results. Postoperative VAS scores at the first and fourth hours were significantly lower in the test group than in the control group (P < .001). Postoperative VRS scores at the first, fourth, and eighth hours were significantly lower in the test group than in the control group (P < .001, P = .002, P = .004, respectively). Analgesic use was significantly higher in the control group at the first postoperative hour (P < .001). Shoulder pain was significantly lower, and patient satisfaction was significantly higher in the test group relative to the control group (both P < .001). Conclusion. High-volume, low-concentration intraperitoneal bupivacaine resulted in better postoperative pain control and reduced incidence of shoulder pain and analgesic consumption in urgent LC.

Abstract
Left ventricular assist devices (LVADs) are an important therapeutic option for patients with end-stage heart failure waiting for heart transplantation or in older patients as definite therapy for heart failure. Interestingly, about 62% of patients receiving LVADs do not have an automatic implantable cardioverter-defibrillator (AICD) at the time of implantation, although these patients have increased risk of being confronted with dangerous arrhythmia. Therefore, an LVAD system including AICD function is a reasonable alternative for such heart failure patients thereby avoiding a second surgical intervention for AICD implantation. In this article, a newly developed system including LVAD and AICD function is introduced, and we also report its first in vitro testing.

Abstract
Background. Indocyanine green angiography (ICGA) offers the potential to provide objective data for evaluating tissue perfusion of flaps and reduce the incidence of postoperative necrosis. Consensus on ICGA protocols and information on factors that have an influence on fluorescence intensity is lacking. The aim of this article is to provide a comprehensive insight of in vivo and ex vivo evaluation of factors influencing the fluorescence intensity when using ICGA during reconstructive flap surgery. Methods. A systematic literature search was conducted to provide a comprehensive overview of currently used ICGA protocols in reconstructive flap surgery. Additionally, ex vivo experiments were performed to further investigate the practical influence of potentially relevant factors. Results. Factors that are considered important in ICGA protocols, as well as factors that might influence fluorescence intensity are scarcely reported. The ex vivo experiments demonstrated that fluorescence intensity was significantly related to dose, working distance, angle, penetration depth, and ambient light. Conclusions. This study identified factors that significantly influence the fluorescence intensity of ICGA. Applying a weight-adjusted ICG dose seems preferable over a fixed dose, recommended working distances are advocated, and the imaging head during ICGA should be positioned in an angle of 60° to 90° without significantly influencing the fluorescence intensity. All of these factors should be considered and reported when using ICGA for tissue perfusion assessment during reconstructive flap surgery.

Abstract
Background. Compared with open surgery, minimally invasive surgery is limited by reduced sensation of tissue properties. A laparoscopic grasper with integrated haptic feedback technology that improves the ability to sense tissue properties might provide a solution. The force reflecting operation instrument (FROI) is a new laparoscopic grasper, designed to provide information about the interaction forces between the instrument and tissue through resistance in the handle. This pilot study aimed to assess the functionality of the FROI compared with a conventional grasper in an in vivo setting. Methods. In this randomized trial, we used a standard laparoscopic surgical setup to perform laparoscopic surgery in pigs. In all, 11 surgeons performed colorectal, gynecological, or urological procedures, once with the FROI and once with a conventional grasper. Participants were asked to complete the NASA Task Load Index Rating Scale and rate 5 specific features for both graspers. To capture opinions on the overall functionality of the FROI, participants were asked to answer 8 open questions. Results. The surgeons reported that the use of the FROI significantly improved tissue consistency perception, arterial pulse detection, and force control compared with the conventional grasper. No significant differences were found in surgeons' muscular strain or operative time. The most emphasized topics in the open questions were improved soft-tissue handling and importance for complex procedures. Conclusion. Through this first in vivo analysis of the functionality of the FROI, a multispecialty group of laparoscopic surgeons confirmed the added value of haptic feedback technology in a live surgical setting.

Abstract
PURPOSE Targeted embolization of gastrointestinal (GI) arteries can modify hormonal production. We aimed to evaluate the impact of the embolization of the gastroduodenal artery (GDA) on the activity of foregut mucosa. METHODS The GDA's duodenal branch was embolized in 12 Yucatan pigs using 100-300 µm (group A; n = 4) or 300-500 µm (group B; n = 4) microspheres, followed by coiling of the branch. In 4 animals (sham), only saline was injected. The levels of GI hormones (ghrelin, glucose-dependent insulinotropic peptide [GIP], glucagon-like peptide-1 [GLP-1], insulin, peptide YY [PYY], leptin) and the gene expression of sodium-glucose-linked transporter-1 (SGLT-1) and glucose transporter-2 (GLUT-2) were assessed before (T0), 1 hour (T1), 1 month (T2), 3 months (T3), and 6 months (T4) after embolization. RESULTS In group A, a segmental duodenal stenosis occurred in all cases, which required balloon dilatation. There was a significant drop in the baseline glycemia in group A at T1 and T4 versus sham. Ghrelin was reduced in group A versus baseline and versus group B at T2 and T3 and versus sham at T1 and T3. Insulin was significantly lower in group A versus B at T1 and at T4 but not versus sham. SGLT-1 expression increased in B and sham at T4, while it remained stable in group A. GLUT-2 expression increased in sham at T4 but not in A or B. CONCLUSIONS GDA embolization induced a decrease in ghrelin production and influenced expression of glucose carriers in the foregut mucosa.

Abstract
Background. Current techniques for localization and resection of lung nodules carry many intraoperative challenges for surgeons. This article proposes a new localization method for diagnosis and treatment of pulmonary nodules, which provides a navigational system for more accurate lung resection. Methods. We report the case of a 77-year-old female with a pulmonary nodule of the right lower lobe. A nonradioactive localization technology, known as SAVI SCOUT (Cianna Medical Inc, Aliso Viejo, CA), was placed by interventional radiology under computed tomography guidance preoperatively. Using the SCOUT Wire-Free Radar Localization System, the pulmonary nodule was robotically localized and resected. SCOUT removal was confirmed using the Trident Specimen Radiology System. The efficacy of this procedure was evaluated in terms of ease of use and procedure time by interventional radiology, surgical resection accuracy, diagnostic accuracy, simplicity, and ease to implement this technology in an existing hospital. Results. The SCOUT system allowed for the first reported case of successful SCOUT placement in lung tissue, targeted the pulmonary nodule intraoperatively, and facilitated accurate lung resection. Conclusions. The SCOUT system shows promising advancements in the ability to eliminate many challenges currently seen with lung nodule localization and resection.

Abstract
BACKGROUND During minimally invasive surgery, efficient and nontoxic hemostats are important for difficult to access bleeding areas. Polylactic acid is an ecofriendly hemostatic agent and we aimed to evaluate the efficacy of a polylactic acid nonwoven fabric (PLAF) developed by Toray Industries, Inc, on liver hemostasis in a preclinical study. MATERIALS AND METHODS PLAF consists of both 1-µm diameter fibers and 100-µm diameter beaded fibers. Four rats were used, and 2 trough-shaped resections of the liver parenchyma were performed (n = 8 lobes). Immediately after the resection, PLAF (PLAF group: n = 4 lobes) or rayon gauze (Rayon group: n = 4 lobes) were applied on the resected plane and compressed manually. We compared the mean time to hemostasis and blood loss per lobe, as well as histological findings between the groups. RESULTS The PLAF group had a significantly shorter bleeding time ( P = .006), and showed lower blood loss compared with the Rayon group ( P = .076). Histopathological evaluation showed a large amount of beads on the liver surface in the PLAF group. Aggregated red blood cells evident by electron microscopy and von Willebrand factor immunofluorescence were seen surrounding the beads. The PLAF group showed significantly greater von Willebrand factor expression than the Rayon group ( P = .004). DISCUSSION This new PLAF showed superior outcomes thanks to its unique characteristic of forming beaded nanofibers, and it has the potential to be an efficient hemostat in minimally invasive surgery in the human body.

Abstract
BACKGROUND There is paucity of data about the impact of using magnification on rate of pancreatic leak after pancreaticoduodenectomy (PD). The aim of this study was to show the impact of using magnifying surgical loupes 4.0× EF (electro-focus) on technical performance and surgical outcomes of PD. PATIENTS AND METHOD This is a propensity score-matched study. Thirty patients underwent PD using surgical loupes at 4.0× magnification (Group A), and 60 patients underwent PD using the conventional method (Group B). The primary outcome was postoperative pancreatic fistula. Secondary outcomes included operative time, intraoperative blood loss, postoperative complications, mortality, and hospital stay. RESULTS The total operative time was significantly longer in the loupe group ( P = .0001). The operative time for pancreatic reconstruction was significantly longer in the loupe group ( P = .0001). There were no significant differences between both groups regarding hospital stay, time to oral intake, total amount of drainage, and time of nasogastric tube removal. Univariate and multivariate analyses demonstrated 3 independent factors of development of postoperative pancreatic fistula: pancreatic duct <3 mm, body mass index >25, and soft pancreas. CONCLUSION Surgical loupes 4.0× added no advantage in surgical outcomes of PD with regard to improvement of postoperative complications rate or mortality rate.

Abstract
BACKGROUND Although various devices have been clinically used for laparoscopic liver resection (LLR), the best device for liver parenchymal transection remains unknown. Olympus Corp (Tokyo, Japan) developed a laparoscopic hybrid pencil (LHP) device, which is the first electric knife to combine ultrasound and electric energy with a monopolar output. We aimed to evaluate the feasibility of using the LHP device and to compare it with the laparoscopic monopolar pencil (LMP) and laparoscopic ultrasonic shears (LUS) devices for LLR in a porcine model. METHODS Nine male piglets underwent laparoscopic liver lobe transections using each device. The operative parameters were evaluated in the 3 groups (n = 24 lobes) during the acute study period. The imaging findings from contrast-enhanced computed tomography and histopathological findings of autopsy on postoperative day 7 were compared among groups (n = 6 piglets) during the long-term study. RESULTS The transection time was shorter ( P = .001); there was less blood loss ( P = .018); and tip cleaning ( P < .001) and instrument changes were less often required ( P < .001) in the LHP group than in the LMP group. The LHP group had fewer instances of bleeding ( P < .001) and coagulator usage ( P < .001) than did the LUS group. In the long-term study, no postoperative adverse events occurred in the 3 groups. The thermal spread and depth of the LHP device were equivalent to those of the LMP and LUS devices (vs LMP: P = .226 and .159; vs LUS: P = 1.000 and .574). CONCLUSIONS The LHP device may be an efficient device for LLR if it can be applied to human surgery.

Abstract
Intraoperative neuromonitoring during thyroid surgery has been used to successfully prevent permanent neurological injury by early identification of anatomical variants. Proper interpretation of neuromonitoring data requires knowledge of what factors might affect the data. In this study, we examined the effect of surgical positioning on the latency and amplitude of neural recordings made from the vocalis muscle during thyroid surgery. A retrospective review was performed of 145 patients who underwent thyroid surgery. Eighty-three had open cervical procedures, and 62 had robotic-assisted transaxillary procedures. Intraoperative neuromonitoring recordings were made by stimulation of the vagus and recurrent laryngeal nerves for both groups. Ultrasound measurements were made of a subset of the transaxillary patients immediately before and after arm positioning. Groups differed only on right-sided recordings. Patients with transaxillary surgeries had significantly shorter latencies evoked from the vagus nerve. We found that vagus nerve-evoked latencies were also correlated to ultrasound measurements of the nerves. Surgical positioning during thyroid surgery is a factor that may affect intraoperative neuromonitoring data and should be taken into account by the surgeon during interpretation.

Abstract
The aim of this pilot study is to investigate the ability of an electronic nose (e-nose) to distinguish malignant gastric histology from healthy controls in exhaled breath. In a period of 3 weeks, all preoperative gastric carcinoma (GC) patients (n = 16) in the Beijing Oncology Hospital were asked to participate in the study. The control group (n = 28) consisted of family members screened by endoscopy and healthy volunteers. The e-nose consists of 3 sensors with which volatile organic compounds in the exhaled air react. Real-time analysis takes place within the e-nose, and binary data are exported and interpreted by an artificial neuronal network. This is a self-learning computational system. The inclusion rate of the study was 100%. Baseline characteristics differed significantly only for age: the average age of the patient group was 57 years and that of the healthy control group 37 years (P value = .000). Weight loss was the only significant different symptom (P value = .040). A total of 16 patients and 28 controls were included; 13 proved to be true positive and 20 proved to be true negative. The receiver operating characteristic curve showed a sensitivity of 81% and a specificity of 71%, with an accuracy of 75%. These results give a positive predictive value of 62% and a negative predictive value of 87%. This pilot study shows that the e-nose has the capability of diagnosing GC based on exhaled air, with promising predictive values for a screening purpose.

Abstract
BACKGROUND The term big data refers to databases that include large amounts of information used in various areas of knowledge. Currently, there are large databases that allow the evaluation of postoperative evolution, such as the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP), the Healthcare Cost and Utilization Project (HCUP) National Inpatient Sample (NIS), and the National Cancer Database (NCDB). The aim of this review was to evaluate the clinical impact of information obtained from these registries regarding gastroesophageal surgery. METHODS A systematic review using the Meta-analysis of Observational Studies in Epidemiology guidelines was performed. The research was carried out using the PubMed database identifying 251 articles. All outcomes related to gastroesophageal surgery were analyzed. RESULTS A total of 34 articles published between January 2007 and July 2017 were included, for a total of 345 697 patients. Studies were analyzed and divided according to the type of surgery and main theme in (1) esophageal surgery and (2) gastric surgery. CONCLUSIONS The information provided by these databases is an effective way to obtain levels of evidence not obtainable by conventional methods. Furthermore, this information is useful for the external validation of previous studies, to establish benchmarks that allow comparisons between centers and have a positive impact on the quality of care.

Abstract
BACKGROUND The lungs are among the first organ affected by remote metastases from many primary tumors. The surgical resection of isolated pulmonary metastases represents an important and effective element of therapy. This is a retrospective study about our entire experience with pulmonary resection for metastatic cancer using 1318-nm neodymium-doped yttrium-aluminum garnet laser. METHOD In this single-institution study, we retrospectively analyzed a group of 209 patients previously treated for primary malignant solid tumors. We excluded 103 patients. The number and location of lesions in the lungs was determined using chest computed tomography and positron emission tomography-computed tomography. Disseminated malignancy was excluded. All pulmonary laser resections are performed via an anteroaxillary muscle-sparing thoracotomy. All lesions were routinely removed by laser with a small (5-10 mm) margin of the healthy lung. Patients received systematic lymph node sampling with intraoperative smear cytology of sampled lymph nodes. RESULTS Mortality at 2 years from the first surgery is around 20% (10% annually). This value increases to 45% in the third year. The estimated median survival for patients who underwent the first surgery is reported to be approximately 42 months. CONCLUSION Our results show that laser resection of lung metastases can achieve good result, in terms of radical resection and survival, as conventional surgical metastasectomy. The great advantage is the possibility of limiting the damage to the lung. Stapler resection of a high number of metastases would mutilate the lung.

Abstract
Surgery is a science and an art, which is mastered through years of training and refined by the accumulation of individual experience and preference. Continuing professional development (CPD) is a concept that emphasizes a self-directed approach to education. Coaching is a process that leads to increased utilization of a person's current skills and resources without counselling or advising. Coaching in surgery could be used to facilitate and optimize feedback and reflection, thus enhancing performance and outcomes through elite performance of an operative procedure. Therefore, it can be applied under the umbrella of CPD. Ultimately also emphasizing that better quality surgery is not necessarily purely based on technical outcomes, it is a combination of both technical and nontechnical practice. Coaching of surgeons is a conceptually formidable tool in the successful implementation of effective CPD programs. CPD currently provides an opportunity for surgeons to gain access to constantly evolving medical knowledge and technique; however, there is no accountability to its understanding or implementation. Coaches have the potential to provide confidential appraisal and feedback in a constructive approach with the aim to eliminate any barriers to the transfer of technique and knowledge.

Abstract
BACKGROUND In large incisional hernias and after laparostoma midline closure may be impossible. A novel abdominal wall expander system (AWEX) is proposed and evaluated. METHODS In patients with large incisional hernias and laparostoma where primary midline closure was impossible, AWEX was used. Patients undergoing abdominal wall reconstruction using AWEX between May 2012 and December 2015 were included. Intraoperative the abdominal wall was stretched by attaching the midline fascia borders to a retraction system under tension for 30 minutes. Length and width of the hernia defect were measured in preoperative computed tomography. Width gain after AWEX procedure, operative time, morbidity, and presence of remaining midline gap was evaluated. Patients were followed for hernia recurrence. RESULTS Ten patients with incisional hernias (N = 4) and grafted laparostoma (N = 6) underwent abdominal wall reconstruction using AWEX. Median (interquartile range) length and width of the hernia defect was 18.0 (15.0-20.5) and 12.0 (11.8-13.3) cm. Width gain after AWEX was 8.5 (8.0-10.5) cm. Operative time was 270 (135-379) minutes. The major morbidity was 20%. In 4 patients a gap of 4 (4-5) cm was bridged by intraperitoneal onlay mesh. After a median follow-up of 21 (7-36) months no hernia recurrence was observed. CONCLUSIONS Stretching of the abdominal wall that has been shown successful using progressive restressed retention sutures and progressive preoperative pneumoperitoneum is reduced from days and weeks to 30 minutes in AWEX. AWEX is a promising alternative to component separation in repair of large incisional hernias. After refinement of the system prospective evaluation is required.

Abstract
PURPOSE Absorbable meshes used in inguinal hernia repair are believed to result in less chronic pain than permanent meshes, but concerns remain whether absorbable meshes result in an increased risk of recurrence. The aim of this study was to present an overview of the advantages and limitations of fully absorbable meshes for the repair of inguinal hernias, focusing mainly on postoperative pain and recurrence. METHODS This systematic review with meta-analyses is based on searches in PubMed, Embase, Cochrane, and Psychinfo. Included study designs were case series, cohort studies, randomized controlled trials (RCTs), and non-RCTs. Studies had to include adult patients undergoing an inguinal hernia repair with a fully absorbable mesh. RESULTS The meta-analyses showed no difference in recurrence rates (median 18 months follow-up) and chronic pain rates (1 year follow-up) between absorbable- and permanent meshes. Crude chronic pain rates for the RCTs were 2.1% for the absorbable meshes and 7.6% for the permanent meshes. For the absorbable meshes, medial hernias were more susceptible for recurrence compared with lateral hernias ( P < .0005). None of the studies reported allergic reactions or other serious adverse events related to the absorbable mesh. CONCLUSIONS Patients with an absorbable mesh seem to have less chronic pain following inguinal hernia surgery compared with permanent meshes, without increased risk of recurrence.

Abstract
Prosthetic reinforcement reduces the recurrence rate of large paraesophageal hernias (PEH), but the use of synthetic or biosynthetic mesh in the repair remains controversial. PEH repair has reported recurrence rates of 12% to 42%, and primary repair of PEH by suture closure under tension is at high risk of disruption. Synthetic mesh use in large PEH repair has shown to reduce recurrence but can lead to problems including mesh erosion, ulceration, stricture, and dysphagia. The objective of this study was to examine the long-term safety and efficacy of Strattice biologic mesh, a porcine acellular dermal matrix, in crural reinforcement of laparoscopic large PEH repair. Thirty-five patients with symptomatic PEH (>5 cm) were consented to receive Strattice for PEH repair. Patients were seen in clinic preoperatively, at surgery, and 2 weeks, 6 months, and 12 months postoperatively. Patients were given a standard subjective reflux test at each visit and a 12-month barium swallow X-ray to test for recurrence. Hernia recurrence was documented in 14.3% of cases by the end of the 1-year follow-up. Symptoms improved in 75% to 100% of patients by 6 months, and 33% to 100% of patients were still reporting symptom improvement at 12 months. Strattice mesh in PEH repair results in similar outcomes to other absorbable meshes, and the recurrence rate is within the 12% to 42% range of recurrences reported in studies outside of our institution. The use of Strattice mesh in large PEH repair had results similar to other biomaterial meshes and successfully decreased patients' symptom scores through surgical intervention.

Abstract
BACKGROUND Fecal incontinence (FI) represents a large source of morbidity and is a challenging clinical problem to manage. InterStim was approved to treat FI in 2011. Little is known about its adoption. We sought to characterize patterns of use of Interstim since Food and Drug Administration approval for FI. METHODS The New York State SPARCS database was used to evaluate InterStim use for FI from 2011 to 2014. The primary endpoint was the number of successful implantations of InterStim. Secondary endpoints included device removal, median time to removal of device, 90-day infection rates, and percentage of procedures performed by surgeon specialty and geographic location. RESULTS A total of 369 patients with FI underwent "Stage 1" of InterStim from 2011 to 2014. A total of 302 patients underwent "Stage 2," yielding a trial period failure rate of 18.2%. The majority of patients who underwent successful implantation were female (87.7%) and White (78.8%). Twenty-nine patients underwent device removal after a median duration of 147 days. Estimated risk of removal at median follow-up of 2 years was 11.8%. Colorectal surgeons comprised 51.1% of all providers followed by gynecologic (24.4%) and urologic surgeons (17.8%). A total of 71.7% of providers performed <5 procedures, while 3 of the highest volume providers performed 50.7% of all procedures. CONCLUSIONS InterStim for FI has been used by a wide variety of providers in New York State although only a few high-volume providers have performed the majority of procedures. White, female patients with Medicare are the most common recipients of InterStim. Further work must be done to develop strategies for improving access to this technology and to determine whether volume relates to outcomes.

Abstract
Background Robotic-assisted radical cystectomy (RARC) is gaining traction as a surgical approach, but there are limited data on patient-reported outcomes for this technique compared to open radical cystectomy (ORC). Objective To compare health-related quality of life (HRQoL) and short-term convalescence among bladder cancer patients who underwent ORC and RARC. Methods Review of a single-institution bladder cancer database was conducted. Baseline and postoperative HRQoL was evaluated using the Bladder Cancer Index (BCI) for 324 patients who had ORC (n = 267) or RARC (n = 57) between 2008 and 2012. The BCI assesses function and bother in urinary, bowel, and sexual domains. Among 87 distinct patients (ORC n = 67, RARC n = 20), we also evaluated short-term postoperative convalescence using the Convalescence and Recovery Evaluation (CARE) questionnaire. Our primary outcomes were HRQoL within 12 months and short-term convalescence within 6 weeks following cystectomy. We fit generalized estimating equation regression models to estimate longitudinal changes in BCI scores within domains, and CARE domain score differences were tested with Wilcoxon rank-sum tests. Results Clinical characteristics and baseline BCI/CARE scores were similar between the 2 groups (all P > .05). Within 1 year after surgery, recovery of HRQoL across all BCI domains was comparable, with scores nearly returning to baseline at 1 year for all patients. CARE scores at 4 weeks revealed that patients treated with ORC had better pain (29.1 vs 20.0, P = .02) domain scores compared to RARC. These differences abated by week 6. Conclusions HRQoL recovery and short-term convalescence were similar in this cohort following ORC and RARC.

Abstract
Objective We aim to evaluate the technique of identifying parathyroid glands with carbon nanoparticle suspension (CNPS) in thyroid surgeries from the perspectives of degrees of declining intact parathyroid hormone (iPTH), operation time, and time of postoperative stay. Methods A total of 156 patients who underwent thyroid surgeries in General Surgical Department of Xiangya Hospital between May 2012 and May 2015 were involved in the study. A total of 78 patients were injected with CNPS during the surgery (CNPS group); the other 78 patients received normal saline (control group). Cases were classified into 3 surgical approaches: conventional partial thyroidectomy, conventional total thyroidectomy, and endoscopic partial thyroidectomy. Degrees of declining iPTH were tested to determine the severity of parathyroid injury. Operation time and postoperative hospital stay time were recorded. A P value of less than .05 was considered statistically significant. Results For levels of declining iPTH, there was no statistically significant (ss) difference in conventional thyroid surgery. In endoscopic partial thyroidectomy, it was 23.37 ± 16.20 versus 11.94 ± 11.23 pg/mL (P = .02, ss). The operation time of conventional total thyroidectomy was 210.10 ± 83.75 versus 164.84 ± 69.22 minutes (P = .03, ss), while it was 193.04 ± 75.53 versus 127.67 ± 60.06 minutes (P = .007, ss) in endoscopic thyroidectomy. Conclusions CNPS is not beneficial for protecting the function of parathyroid gland in thyroid surgery from the perspective of declining iPTH. Applying CNPS in conventional total thyroidectomy and endoscopic partial thyroidectomy will also lead to significantly prolonged operation time.

Abstract
INTRODUCTION The impact of insurance expansion on the currently insured population is largely unknown. We examine rates of elective surgery in previously insured individuals before and after Massachusetts health care reform. METHODS Using the State Inpatient Databases for Massachusetts and 2 control states (New York and New Jersey) that did not expand coverage, we identified patients aged 69 and older who underwent surgery from January 1, 2003, through December 31, 2010. We studied 5 elective operations (knee and hip replacement, transurethral resection of prostate, inguinal hernia repair, back surgery). We examined statewide utilization rates before and after implementation of health care reform, using a difference-in-differences technique to adjust for secular trends. We also performed subgroup analyses according to race and income strata. RESULTS We observed no increase in the overall rate of selected discretionary inpatient surgeries in Massachusetts versus control states for the entire population (-1.4%, P = .41), as well as among the white (-1.6%, P = .43) and low-income (-2.2%, P = .26) subgroups. We did, however, find evidence for a woodwork effect in the subgroup of nonwhite elderly patients, among whom the rate of these procedures increased by 20.5% (P = .001). Among nonwhites, the overall result reflected increased utilization of all 5 individual procedures, with statistically significant changes for knee replacement (18%, P < .01), back surgery (18%, P = .05), transurethral resection of the prostate (28%, P = .05), and hernia repair (71%, P = .03). CONCLUSION Our findings suggest that national insurance expansion may increase the use of elective surgery among subgroups of previously insured patients.

Abstract
PURPOSE Transumbilical single-port surgery has been associated with less postoperative pain and offers better cosmetic outcomes than conventional 3-port laparoscopic surgery. This study compares the safety and efficacy of transumbilical thoracoscopy and conventional thoracoscopy for lung wedge resection. METHODS The animals (n = 16) were randomly assigned to the transumbilical thoracoscopic approach group (n = 8) or conventional thoracoscopic approach group (n = 8). Transumbilical lung resection was performed via an umbilical incision and a diaphragmatic incision. In the conventional thoracoscopic group, lung resection was completed through a thoracic incision. For both procedures, we compared the surgical outcomes, for example, operating time and operative complications; physiologic parameters, for example, respiratory rate and body temperature; inflammatory parameters, for example, white blood cell count; and pulmonary parameters, for example, arterial blood gas levels. The animals were euthanized 2 weeks after the surgery for gross and histologic evaluations. RESULTS The lung wedge resection was successfully performed in all animals. There was no significant difference in the mean operating times or complications between the transumbilical and the conventional thoracoscopic approach groups. With regard to the physiologic impact of the surgeries, the transumbilical approach was associated with significant elevations in body temperature on postoperative day 1, when compared with the standard thoracoscopic approach. CONCLUSIONS This study suggests that both approaches for performing lung wedge resection were comparable in efficacy and postoperative complications.

Abstract
Robot-assisted surgery is gaining momentum as a new trend in minimally invasive surgery. With limited evidence supporting its use in place of the far less expensive conventional laparoscopic surgery, it has been suggested that marketing pressure is partly responsible for its widespread adoption. The impact of phrases that promote the novelty of robot-assisted surgery on patient decision making has not been investigated. We conducted a discrete choice experiment to elicit preference of partial colectomy technique for a hypothetical diagnosis of colon cancer. A convenience sample of 38 participants in an ambulatory general surgery clinic consented to participate. Each participant made 2 treatment decisions between robot-assisted surgery and conventional laparoscopic surgery, with robot-assisted surgery described as "innovative" and "state-of-the-art" in one of the decisions (marketing frame), and by a disclosure of the uncertainty of available evidence in the other (evidence-based frame). The magnitude of the framing effect was large with 12 of 38 subjects (31.6%, P = .005) selecting robot-assisted surgery in the marketing frame and not the evidence-based frame. This is the first study to our knowledge to demonstrate that words that highlight novelty have an important influence on patient preference for robot-assisted surgery and that use of more neutral language can mitigate this effect.

Abstract
INTRODUCTION Peer-to-peer learning is a well-established learning modality, which has been shown to improve learning outcomes, with positive implications for clinical practice. The purpose of this pilot study was to explore the feasibility of linking students from North America and Europe with a peer-to-peer learning approach. METHODS Face and content validity studies were completed on the previously designed and validated online repository http://www.pilgrimshospital.com. Four medical students from the University of Toronto, Canada, were paired with four students from University College Cork, Ireland. Each student was invited to upload two pieces of information learned from a senior colleague that day. Each student was asked to review the information uploaded by their partner, editing with references if needed. Quantitative and qualitative evaluations of the e-peer system were conducted. RESULTS Over the study period, the system recorded a total of 10 079 individual page views. Questionnaires completed by participants demonstrated that 6/8 found the system either "very easy" or "easy" to use, whereas all found that the system promoted evidenced-based and self-directed learning. Structured interviews revealed 3 main themes: The Peer Connection, Trust in Data Veracity, and Aid to Clinical Learning. CONCLUSION This pilot study demonstrates it is feasible to link students from separate continents in a community of peer-to-peer learning. This is viewed positively by students and enhances evidenced-based learning, and the aspect of peer connectivity was important to participating students. Such an approach encourages peer cooperation and has the potential to disseminate key clinical learning experiences widely.

Abstract
BACKGROUND Correct recognition of the extrahepatic bile ducts is thought to be crucial to reduce the risk of bile duct injuries during various laparoscopic procedures. Image-enhanced laparoscopy techniques, utilizing various optical modalities other than white light, may help in detecting structures "hidden" underneath connective tissue. METHODS A systematic literature search was conducted of studies describing image-enhanced laparoscopy techniques for visualization of the extrahepatic bile ducts. RESULTS In all, 29 articles met inclusion criteria. They describe various techniques in the animal or human setting, including autofluorescence imaging, drug-enhanced fluorescence imaging, infrared thermography, and spectral imaging. This review describes these various techniques and their results. CONCLUSION Image-enhanced laparoscopy techniques for real-time visualization of extrahepatic bile ducts are still in its infancy. Out of the techniques currently described, indocyanine green-enhanced near-infrared fluorescence laparoscopy has the most mature results, but other techniques also appear promising. It can be expected that in the future, image-enhanced laparoscopy might become a routine adjunct to any white-light laparoscopic operation near the hepatic hilum.

Abstract
OBJECTIVE Recent advances in adipose cellular biology have repopularized autologous fat grafting as a method widely used in both reconstructive and aesthetic surgery. This review aims to summarize our current knowledge on autologous fat grafting emphasizing harvesting techniques and processing methods as well as current trends and approaches. METHODS A thorough search of earlier and recent literature until October 2013 was conducted using the terms autologous fat grafting, autologous fat transfer, lipoaspirate, lipoinjection, fat harvest, and lipotransfer in PubMed and ClinicalTrials.gov databases, and relevant English- and German-language articles were included. RESULTS Findings were categorized in a step-by-step approach of the fat grafting procedure into indications, selection of donor site, techniques for harvesting, processing, and reimplantation of autologous fat. CONCLUSIONS Further in-depth knowledge will provide definite answers on fat graft survival; demonstrate safe methods to increase cell viability, grafting outcome predictability; and reliability; enhance safety; and strengthen the scientific and clinical establishment of this increasingly promising method.

Abstract
OBJECTIVE Several studies show that stapled transanal rectal resection (STARR) significantly improves constipation in most patients, while others remain symptomatic for obstructed defecation syndrome (ODS). The aim of the study was to analyze clinical, manometric, and endoanal ultrasonography results in order to find any possible correlation between clinical and instrumental data, particularly in dissatisfied patients, both for those who remain symptomatic for ODS and for patients with new-onset fecal disorders. PATIENTS AND METHODS All patients underwent a preoperative and postoperative assessment based on clinical evaluation, proctoscopy, defecography, anorectal manometry, and endoanal ultrasonography. Furthermore, we asked patients about a subjective satisfaction grading of outcome. RESULTS From January 2007 to December 2009, 103 patients were treated in our department with STARR for ODS. Postoperative endoanal ultrasound did not demonstrate any variations compared with the preoperative one. Postoperative scores showed statistically significant improvement, with respect to the preoperative value, with good and sufficient scores in 79.6% of patients, and an overall rate of satisfaction of 87.1%. Fecal disorders, including also the slightest alteration of continence, occurred in 24% of patients, in particular soiling 1.8%, urgency 7.4%, occasional gas leakage 5.5%, and liquid/solid leakage 9.3%. Anorectal manometry revealed a statistically significant reduction only in sensitivity threshold and maximum tolerated volume compared to patients with no disorders of continence. CONCLUSION Results indicate good satisfaction grading and a statistically significant improvement in scores of constipation. There is no close correlation between satisfaction grading and scores. Besides, the assessment of patient's satisfaction often does not match the objective functional outcome.

Abstract
Thrombotic events in vascular substitutes are the main cause of obliteration of most microvascular prostheses and subsequent failure of microvascular anastomoses. The development of new biomaterials for vascular replacement aims to obtain an ideal graft for microvascular surgery. Completely bioresorbable vascular prostheses with the capacity to induce regeneration and growth of a new vascular segment seem to overcome the limitations of contemporary artificial prostheses, mostly made of artificial materials and lacking the capacity to grow and be remodeled. Autologous vessels are currently the most used material for small-diameter arterial replacement. Immune acceptance is a major advantage offered by this technique, but the time required is a limitation in emergency surgery. The need for a prosthetic graft that would have the same properties as a small-diameter conduit has led investigators to pursue many avenues in vascular biology. This article details the development of microvascular synthetic prostheses, clarifying the current status and the future aims.

Abstract
OBJECTIVES To assess trends in the use of sacral neuromodulation and to measure the magnitude of variation in its use across geographic regions. METHODS We used the State Ambulatory Surgery Database (SASD) from 2002 to 2009 from Florida to identify patients implanted with a neuromodulator. Age- and gender-adjusted rates of implantation were calculated by year and by geographic region, defined by the Hospital Service Area. The coefficient of variation was estimated to quantify the magnitude of variation for different time periods. RESULTS Adjusted rates of sacral neuromodulation increased significantly from 1.1 per 100,000 population in 2002 to 10.4 per 100,000 population in 2009. The majority of cases were performed for overactive bladder. There was a very large amount of geographic variation in rates of these procedures as evidenced by the high coefficients of variation: 1.67 (2002 and 2003), 1.70 (2004 and 2005), 1.49 (2006 and 2007), and 1.05 (2008 and 2009). CONCLUSIONS Rates of sacral neuromodulation have increased dramatically over the past decade. However, these rates of utilization are highly variable across regions, with some regions performing large numbers of these procedures and other regions performing few to no procedures. This range in practice patterns may reflect medical uncertainty surrounding the role of this procedure.

Abstract
Overactive bladder (OAB) is a common syndrome that has a negative impact on daily activities and quality of life. The first-line treatment to manage this condition includes behavioral modifications, physical treatment, and oral pharmacotherapy with antimuscarinics. Botulinum toxin has emerged as an alternative and second-line treatment option for patients with OAB who are refractory to first-line treatment modalities when injected into the detrusor muscle. Although its application in the management of OAB remains off label, studies have shown its efficacy both subjectively and objectively. It is considered as a minimally invasive and reversible alternative. Adequate dosage of the toxin, number of injection sites, and reinjection rates are yet to be determined. This review attempts to provide an update on the current position of botulinum toxin in managing refractory OAB addressing contemporary data on the mechanism of action, technique, safety, complications, and clinical results.
