RESUMO

PURPOSE: The objective of this study is to evaluate the safety and long-term outcomes of GORE Synecor™ in ventral hernia repair (VHR). METHODS: This retrospective, single-center case review analyzed outcomes in patients who underwent VHR with Synecor from May 2016 to December 2022. Primary outcomes were hernia recurrence and mesh infection rates. Secondary outcomes were 30-day morbidity, 30-day mortality, 30-day readmission, re-operation, surgical-site infection (SSI) and occurrence (SSO) rates, and occurrences requiring intervention (SSOI). RESULTS: 278 patients were identified. Mean follow-up was 24.1 (0.2-87.1) months. Mean hernia defect size was 63.4 (± 77.2) cm2. Overall hernia recurrence and mesh infection rates were 5.0% and 1.4% respectively. No mesh infections required full explantation. We report the following overall rates: 13.3% 30-day morbidity, 4.7% 30-day readmission, 2.9% re-operation, 7.2% SSI, 6.1% SSO, and 2.9% SSOI. 30-day morbidity was significantly higher in non-clean (42.1% vs 11.2%, p < 0.01), onlay (OL) mesh (37.0% vs preperitoneal (PP) 16.4%, p = 0.05 vs retrorectus (RR) 15.0%, p < 0.05 vs intraperitoneal (IP) 5.2%, p < 0.001), and open cases (23.5% vs 3.1% laparoscopic vs 4.4% robotic, p < 0.01). SSI rates were significantly higher in non-clean (31.6% vs 5.4%, p < 0.001), OL mesh (29.6% vs RR 11.3%, p < 0.05 vs PP 5.5%, p < 0.01 vs IP 0.0%, p < 0.001), and open cases (15.2% vs 0% laparoscopic vs 0% robotic, p < 0.05). CONCLUSION: Long-term performance of a novel hybrid mesh in VHR demonstrates a low recurrence rate and favorable safety profile in various defect sizes and mesh placement locations.

RESUMO

Surgery remains one of the major treatment options available to patients with esophageal cancer, with high mortality in certain cohorts. The aim of this study was to develop a simple preoperative risk scale based on patient factors, hospital factors, and tumor pathology to predict the risk of perioperative mortality following esophagectomy for malignancy. The Nationwide Inpatient Sample database was used to create the risk scale. Patients who underwent open or laparoscopic transhiatal and transthoracic esophageal resection were identified using International Classification of Diseases, 9th edition codes. Patients <18 years and those with peritoneal disease were excluded. Multivariate logistic regressions were used to define a predictive model of perioperative mortality and to create a simple risk scale. From 1998 to 2011, a total of 23 751 patients underwent esophagectomy. The observed overall perioperative mortality rate for this cohort was 7.7%. Minimally invasive techniques, and operations performed in higher volume centers were protective, whereas increasing age, comorbidities and diagnosis of squamous cell carcinoma were independent predictors of mortality. Based on this population, a risk scale from 0-16 was created. The calibration revealed a good agreement between the observed and risk scale-predicted probabilities. A set of sensitivity/specificity analyses was then performed to define normal (score 0-7) and high risk (score 8-16) patients for clinical practice. Mortality in patients with a score of 0-7 ranged from 1.3-7.6%, compared with 10.5-34.5% in patients with a score of 8-16. This simple preoperative risk scale may accurately predict the risk of perioperative mortality following esophagectomy for malignancy and can be used as a clinical tool for preoperative counseling.

RESUMO

INTRODUCTION: It has been published that patients who underwent gastric bypass surgery have impaired alcohol metabolism, predisposing them to higher rates of intoxication and DUI arrests. Yet the impact of laparoscopic sleeve gastrectomy (LSG) on alcohol metabolism and in particular the long-term effects are still unclear. We hypothesized that LSG does not alter alcohol metabolism. METHODS: A prospective cohort study of patients undergoing LSG was evaluated. Blood alcohol concentration (BAC) was extrapolated using a Breathalyzer(®). Alcohol metabolism was evaluated by determining BAC every 5 min after a single dose of alcohol (5 oz. glass of 14% v/v Malbec wine), until BAC was equal to zero. Subjects were queried about alcohol intoxication symptoms. All parameters were obtained and analyzed preoperatively and at 3 and 12 months postoperatively. RESULTS: Our study consisted of 10 patients (9 female) with a mean age of 46.6 ± 2.2 years and BMI of 43.5 ± 2.2 kg/m(2). The mean percentage excess weight loss was 39.5 ± 3.3 at 3 months and 55.6 ± 4.4 at 12 months. Peak BAC at 20 min was not different at 3 months (0.068 ± 0.007, p = 0.77) or at 12 months (0.047 ± 0.008, p = 0.19) when compared to the preoperative assessment (0.059 ± 0.014). In addition, the time to BAC equal to zero was not significantly different between baseline and the follow-up values (preoperative: 70 ± 9 min, 3 months: 95 ± 18 min, and 12 months: 57 ± 8 min, (p > 0.05). Symptoms of intoxication were not significantly different in patients before and after surgery. CONCLUSIONS: Our study suggests that LSG does not alter alcohol metabolism. Patients who undergo LSG do not have higher levels of intoxication following alcohol consumption and are therefore not prone to higher rates of DUI charges than the general public, in contrast to that previously reported following in patients who undergo gastric bypass surgery.

RESUMO

Left ventricular diastolic dysfunction leads to heart failure with preserved ejection fraction, an increasingly prevalent condition largely driven by modern day lifestyle risk factors. As heart failure with preserved ejection fraction accounts for almost one-half of all patients with heart failure, appropriate nonhuman animal models are required to improve our understanding of the pathophysiology of this syndrome and to provide a platform for preclinical investigation of potential therapies. Hypertension, obesity, and diabetes are major risk factors for diastolic dysfunction and heart failure with preserved ejection fraction. This review focuses on murine models reflecting this disease continuum driven by the aforementioned common risk factors. We describe various models of diastolic dysfunction and highlight models of heart failure with preserved ejection fraction reported in the literature. Strengths and weaknesses of the different models are discussed to provide an aid to translational scientists when selecting an appropriate model. We also bring attention to the fact that heart failure with preserved ejection fraction is difficult to diagnose in animal models and that, therefore, there is a paucity of well described animal models of this increasingly important condition.

RESUMO

BACKGROUND: Within the next few years, the medical industry will launch increasingly affordable three-dimensional (3D) vision systems for the operating room (OR). This study aimed to evaluate the effect of two-dimensional (2D) and 3D visualization on surgical skills and task performance. METHODS: In this study, 34 individuals with varying laparoscopic experience (18 inexperienced individuals) performed three tasks to test spatial relationships, grasping and positioning, dexterity, precision, and hand-eye and hand-hand coordination. Each task was performed in 3D using binocular vision for open performance, the Viking 3Di Vision System for laparoscopic performance, and the DaVinci robotic system. The same tasks were repeated in 2D using an eye patch for monocular vision, conventional laparoscopy, and the DaVinci robotic system. RESULTS: Loss of 3D vision significantly increased the perceived difficulty of a task and the time required to perform it, independently of the approach (P < 0.0001-0.02). Simple tasks took 25 % to 30 % longer to complete and more complex tasks took 75 % longer with 2D than with 3D vision. Only the difficult task was performed faster with the robot than with laparoscopy (P = 0.005). In every case, 3D robotic performance was superior to conventional laparoscopy (2D) (P < 0.001-0.015). CONCLUSIONS: The more complex the task, the more 3D vision accelerates task completion compared with 2D vision. The gain in task performance is independent of the surgical method.

RESUMO

A correctly positioned vehicle head restraint (HR) can reduce whiplash injury risk in collisions, however, HRs are often sub-optimally positioned. The primary aim of this study was to investigate vehicle HR position and driver knowledge of correct HR positioning in an Irish population. Secondary aims were to investigate the associations with driver age, gender and vehicle age. Data collection involved HR measurement and a driver questionnaire (n = 110). Just 27% of drivers had optimal HR positioning, while 30% had poor or marginal positioning. Newer vehicles (<5 years old) had better positioned HR in the horizontal plane (p = 0.036), than older vehicles. Younger drivers (<30 years) were more likely to have poorer positioning of HR (p = 0.002), than the 30 years or over group. Females were more likely to have better vertical positioning of their HR (p = 0.003) than males. Driver knowledge of correct position was variable, and not associated with actual HR position, with 65% knowing the correct vertical positioning standard but only 27% identifying the correct horizontal position. Many drivers have inadequately positioned HR, which needs to be addressed by improved vehicle design and public education.

RESUMO

BACKGROUND: Statins are proven to reduce cardiovascular risk; however, substantial risk remains in patients on statin therapy. Persisting dyslipidaemia is likely to play a contributory role. AIM: To assess the prevalence of persisting lipid abnormalities in patients treated with statins. METHODS: DYSIS was a cross-sectional study of 22,063 patients in Europe and Canada. 900 Irish patients participated. All patients were ≥ 45 years and treated with statins for ≥ 3 months. Data were collected from the patients' records. ESC guidelines were used to classify risk and to define lipid levels. RESULTS: Mean age was 66.1 years with women representing 40.7%. 78.6% were high-risk patients; that is 53.9% with cardiovascular disease (CVD), 20.1% with diabetes and 15.9% with a SCORE risk ≥ 5%. Total cholesterol was not at goal in 34.4% of all patients. LDL-C was elevated in 30.8% of all patients and in 30% at high risk. Low HDL-C was found in 34.7% of high-risk patients compared to 16.9% of patients with an ESC score <5%. In diabetics without CVD, low HDL-C and elevated TGs were found in 46 and 44.3%, respectively. CONCLUSIONS: Despite statin therapy, a significant number of patients have persistent dyslipidaemia. While LDL-C targets are suboptimal in three out of ten patients, the prevalence of low HDL-C and high TGs in high-risk patients is greater than one in three. A more integrated approach to the treatment of patients with dyslipidaemia is warranted. Clinical trials are needed to assess the impact of therapies that raise HDL-C and lower elevated TGs.

RESUMO

BACKGROUND: Single-incision laparoscopic surgery (SILS) has been proposed as a minimally invasive technique with the advantages of smaller external scars and reduced pain. Furthermore, usage of the flexible endoscope for SILS in lieu of the standard laparoscope provides distinct visualization advantages. This video shows a single-incision cholecystectomy performed using a single incision placed through the umbilicus. METHODS: A 39-year-old woman with chronic symptomatic cholelithiasis was enrolled under institutional review board protocol to undergo SILS. She had previously undergone a laparoscopic tubal ligation. A single incision was made using the previous umbilical incision, and the abdomen was entered in an open fashion. The flexible endoscope was placed directly through the fascial incision, with two 5-mm ports on either side. Adhesions to the gallbladder were taken down with the harmonic scalpel. Dissection proceeded using an articulating grasper and retraction to identify the cystic duct and artery. The duct and artery were serially clipped and divided. The cystic duct was additionally secured with a loop ligature. The gallbladder was cauterized from the liver bed using the articulating hook cautery and extracted through the wound. RESULTS: The final incision placed at the base of the umbilicus was 7 mm long. The operative time was 58 min, with minimal blood loss recorded. The patient was discharged home on the day of the procedure and did not experience any postoperative complications. CONCLUSIONS: Single-incision cholecystectomy can be performed safely through one incision in the umbilicus, optimizing cosmesis. Substitution of the flexible endoscope for the standard laparoscope allows many greater degrees of visualization in SILS. This allows clear identification of the biliary ductal anatomy, allowing cholecystectomy to proceed safely. Placement of the endoscope directly through the incision decreases the profile of ports through the incision and increases maneuverability.

RESUMO

AIM: To audit the cardiac rehabilitation (CR) service in the Northwest. METHODS: Patients were identified on the CR Information System. Indications, rate of uptake, demographics and complications were all recorded. Cardiovascular risk factors and exercise capacity before and after CR were compared. Systems for referral and phases I-IV were analysed. RESULTS: Three hundred ninety-two patients were offered CR in 2006. 151 patients completed phase III. One-fifth attended outreach centres. Mean age was 62.9. 22% were female. No serious adverse events occurred during exercise training. A smoking quit rate of 26% was achieved. Mean blood pressures pre and post CR were 141/76 and 131/73 mmHg, respectively. The mean increase in exercise capacity was 2.85 mets. CONCLUSIONS: CR in the Northwest provides a modern evolving programme. Enhanced referral rate, reduction in the duration of phase II, increased participation by women and improved accessibility will consolidate its contribution to cardiovascular disease management in this region.

RESUMO

The aim of this meta-analysis was to compare clinical outcome following laparoscopic and robotic Nissen fundoplication. A systematic literature search of Medline, Embase and Cochrane Library databases was performed. Primary outcome measures were the requirement for re-operation, postoperative mortality and postoperative dysphagia. Secondary outcome measures were operative time, length of hospital stay, operative complications and cost. Six randomized trials, of 226 patients, were included in this meta-analysis. There was no significant difference in requirement for re-operation or in postoperative dysphagia. There was a significantly reduced total operative time in the laparoscopic group (weighted mean difference = 4.154; 95% CI = 1.932-6.375; p = 0.0002). There was no significant difference between robotic and laparoscopic groups for hospital stay or operative complications. Clinical results from robotic Nissen fundoplication were comparable to the standard laparoscopic approach, but there was associated increased operative time and procedure cost.

RESUMO

INTRODUCTION: Natural orifice surgery has evolved from a preclinical setting into a common occurrence at the University of California San Diego (UCSD). With close to 40 transvaginal cases, we have become comfortable with this technique and are exploring other indications. One of the perceived advantages in natural orifice surgery is the potential reduction in the incidence of hernia formation. Patients with abdominal wall hernias may be at increased risk of forming additional hernias at incision sites. In addition, patients with recurrent incisional hernias may, likewise, be at increased risk. We believe that reducing or eliminating abdominal wall incisions may be of benefit in the repair of abdominal wall hernias. Here, we describe what we believe to be the first natural orifice transluminal endoscopic surgical (NOTES) approach to the repair of an abdominal wall hernia. METHODS: The patient is a 38-year-old female with a painful recurrent umbilical hernia, previously repaired 8 years prior with a polypropylene-based mesh. The patient underwent a transvaginal recurrent umbilical hernia repair with one other 5-mm port in the abdomen for safety. RESULTS: The patient had no intraoperative or postoperative complications. At 5 months follow up, the patient had no complaints, no evidence of hernia recurrence, and was very pleased with her result. CONCLUSIONS: The repair of primary and incisional hernias of the ventral abdominal wall via a transvaginal approach is technically feasible, and the result of our initial case was exceptional. However, there are still significant obstacles which must be addressed before this approach can be widely utilized. These obstacles include safe entrance into the abdominal cavity via a transvaginal approach, the proper mesh to be placed during the repair, and the risk of infection.

RESUMO

BACKGROUND: Quality indicators are increasingly emphasized in the performance of colonoscopy. This study aimed to determine the standard of care rendered by surgeon-endoscopists in a Veterans Affairs (VA) medical center by evaluating the indications for colonoscopy and outcome performance measures according to established quality indicators for colonoscopy. METHODS: A prospective standardized computer endoscopic reporting database (ProVation MD) was retrospectively reviewed. All colonoscopies performed by attending surgeons at the San Diego VA medical center between 1 January 2004 and 31 July 2007 were included in the study. Patients with charts that had incomplete reporting were excluded. The quality indicators used included the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) criteria for colorectal cancer screening, the American Cancer Society (ACS) guidelines for postcancer resection surveillance, and the American Society of Gastrointestinal Endoscopists (ASGE) quality indicators for colonoscopy. RESULTS: The data for 558 patients (96% men) were analyzed. The average patient age was 63 years (range, 25-93 years). Almost all the colonoscopies (99%) were performed in accordance with established criteria. The most common indications for colonoscopy were screening (n = 143, 26%), non-acute gastrointestinal bleeding (n = 127, 23%), polyp surveillance (n = 100, 18%), postcancer resection surveillance (n = 91, 17%), abdominal pain (n = 19, 4%), and anemia (n = 14, 3%). Postcancer resection surveillance colonoscopies were performed according to recommended criteria in 98% of the cases. The cecal intubation rate was 97%, and the overall adenoma detection rate was 26%. Two patients (<1%) experienced complications requiring intervention. CONCLUSION: The study data indicate that surgeon-performed colonoscopies meet standard quality criteria for indications and performance measures. The authors therefore conclude that surgeon-endoscopists demonstrate proficiency in the standard of care for colonoscopy examinations.

RESUMO

AIM: IFIS is a recently described condition observed during cataract surgery. However, its true incidence in the U.K. population is unknown. Our aim was to assess the incidence of IFIS associated with tamsulosin in patients undergoing cataract surgery in a U.K. district general hospital. METHOD: A prospective observational study of patients on tamsulosin undergoing cataract surgery was carried out over a six month period to determine the incidence of IFIS and to document outcomes of those cases. The patients were identified during routine pre-operative assessment. RESULTS: 1462 cataract cases were performed over six months. From these cases, 23 eyes of 16 patients who were taking Tamsulosin were recruited into the study. All the patients were men and the mean age was 76 years. A small pupil was demonstrated intra-operatively in 69% (16/23) of the eyes. A floppy iris or iris prolapse during surgery was noted in 57% (13/23) of the eyes. Complications reported included posterior capsule rupture in one case (4%) and iris trauma in five cases (22%). A best corrected visual acuity of 6/9 or better was achieved in 21/23 cases. The incidence of IFIS in patients undergoing cataract surgery over six months is 0.9%. CONCLUSION: IFIS appears to be strongly associated with tamsulosin use. The increasing use ofthis drug in the elderly male population is likely to increase the workload on our cataract service. Prospective risk stratification for such patients to be operated by senior surgeons is therefore recommended.

RESUMO

BACKGROUND: Esophagectomy is a technically demanding operation with high procedure-related morbidity and mortality rates. Minimally invasive techniques were introduced in the late 1980s in an effort to decrease the invasiveness of the procedure. Data concerning the use of robotic systems for esophageal cancer are scarce in the literature. The goal of this report is to describe the authors' early experience using robotically assisted technology to perform transhiatal esophagectomy (RATE). METHODS: Between September 2001 and May 2004, 18 patients underwent RATE at the authors' institution. A retrospective review of prospectively collected data was performed. Gender, age, postoperative diagnosis, operative time, conversion rate, blood loss, hospital stay, length of the follow-up period, and complications were assessed. RESULTS: At the authors' institution, 18 patients underwent RATE, including 16 men (89%), with a mean age of 54 years (range, 41-73 years). The RATE procedure was completed for all 18 patients (100%). The mean operative time was 267 +/- 71 min, and estimated blood loss was 54 ml (range, 10-150 ml). The mean intensive care unit stay was 1.8 days (range, 1-5 days), and the mean hospital stay was 10 days (range, 4-38 days). A total of 12 perioperative complications occurred for 9 patients, including 6 anastomotic leaks, 1 thoracic duct injury, 1 vocal cord paralysis, 1 pleural effusion, and 2 atrial fibrillations. Anastomotic stricture was observed in six patients. There were no perioperative deaths. Pathologic examination of the surgical specimen yielded an average of 14 lymph nodes per patient (range, 7-27). During the mean follow-up period of 22 +/- 8 months, 2 patients died, 2 were lost to follow-up evaluation, 3 had recurrence, and 11 were disease free. CONCLUSION: The current study shows that RATE, with its decreased blood loss, minimal cardiopulmonary complications, and no hospital mortality, represents a safe and effective alternative for the treatment of esophageal adenocarcinoma.

RESUMO

BACKGROUND: Bowel anastomosis is one of the most challenging and difficult tasks to perform during natural orifice translumenal endoscopic surgery (NOTES). The difficulty is mainly due to the technical limitations of the endoscopic instruments available. Currently, endoscopic clips, T-bar sutures, or cumbersome suturing devices are used. A dual-lumen NOTES approach can facilitate bowel resection in a pig model by allowing the use of laparoscopic staplers through the rectum. METHODS: Acute studies were performed on four 40-kg pig models. The dual-lumen NOTES approach was used to perform small bowel resection and anastomosis. An endoscope was passed into the stomach and pushed through the stomach wall into the peritoneal cavity (first lumen), and a 12-mm trocar was placed through the anterior rectal wall, allowing access to the peritoneum (second lumen). Handling of the bowel, resection, and anastomosis were performed using endoscopic instruments through the gastric lumen and laparoscopic instruments through the rectal lumen. The resected small bowel then was removed through the rectum. RESULTS: Small bowel resection and anastomosis was successfully completed in all four animals using the dual-lumen NOTES approach. The laparoscopic stapler was used one more time to close the gastrotomy through the rectal port. At autopsy, intact suture lines were noted at the bowel anastomosis and at the stomach, with no evidence of leak from either site. CONCLUSIONS: Performing a sutured anastomosis in NOTES is complex and time consuming. The use of stapling devices designed for laparoscopic procedures greatly facilitates gastrointestinal tract operations in NOTES. Using both the upper and lower gastrointestinal tract as entry sites for NOTES eliminates some of the current technical limitations of these procedures.

RESUMO

AIM: To report on visual acuity (VA) and angiographic outcomes in patients presenting with subfoveal choroidal neovascular membranes (CNV) secondary to punctate inner choroidopathy (PIC), treated with photodynamic therapy (PDT) with verteporfin combined with systemic corticosteroids. METHODS: A prospective case series of patients with subfoveal CNV secondary to PIC was analysed. All patients were treated with PDT combined with oral prednisolone (1 mg/kg body weight/day) which was started 5 days before PDT. Fluorescein angiography was performed at baseline and every 3 months post-treatment to establish the size, position, and activity of the CNV. Visual acuity was measured using the ETDRS scale. Further PDT treatment was carried out at follow-up visits if there was angiographic evidence of ongoing CNV activity. RESULTS: Five female patients with a mean age of 30.4 years (range 25-43 years) were treated over a 12-month period. The mean greatest linear diameter (GLD) of the CNV was 1.66 mm (range 0.46-3.28 mm). A mean improvement in vision of nine ETDRS letters (range -15-20 letters) after treatment was found, which was maintained at final follow-up. The mean follow-up time was 12 months (range 10-14 months). The mean number of PDT treatments was two (range 1-3). CONCLUSIONS: The vaso-occlusive effect of PDT combined with the vasostatic and anti-inflammatory effect of systemic oral prednisolone appears to be a safe and effective option in the primary treatment of subfoveal CNV in patients with PIC.

RESUMO

BACKGROUND: The number of living-related donor kidney transplantations have increased since the advent of minimally invasive surgery. Robotic technology has emerged as a promising alternative to laparoscopic techniques. The authors reviewed their institution experience with robotic hand-assisted donor nephrectomies (RHADNs). METHODS: Between August 2000 and April 2006, 273 robotically assisted left donor nephrectomies were performed using a hand-assisted technique. Prospectively collected information for 214 patients regarding complications, hospital stay, blood loss, warm ischemia time, operative time, and outcomes is presented. RESULTS: The cohort of donors included 110 men and 104 women with a mean age of 36 years (range, 18-61 years). These donors included 86 African Americans, 46 Caucasians, 74 Hispanics, and 8 of other races. Left renal artery anomalies were found in 61 patients (29%). Four patients underwent conversion to open surgery. The hospital stay was 2.3 days (range, 1-8 days), the blood loss 82 ml (range, 10-1,500 ml), and the mean warm ischemia time 98 s (range, 50-200 s). The operative time was 201 min (range, 100-320 min) for the first 74 cases, 129 min (range, 65-240 min) for the second 70 cases, and 103 min for the last 70 cases (p < 0.001), for an overall average of 150 min. Complications decreased significantly after the first 74 cases. The 1-year patient survival rate was 100%, and the 1-year graft survival rate was 98%. The average recipient creatinine at 6 months was 1.4 mg/dl. CONCLUSIONS: Specific changes in operative technique over time have improved patient safety and diminished complications with RHADN. Currently, RHADN can be performed expeditiously with a minimal rate of complications and conversion to open procedure by a surgical team with appropriate training and experience.
