Introduction
The objective of this study is to assess the usefulness of an evaluation system of surgical skills based on motion analysis of laparoscopic instruments.Method
This system consists of a physical laparoscopic simulator and a tracking and assessment system of technical skills in laparoscopy. Six surgeons with intermediate experience (between 1 and 50 laparoscopic surgeries) and 5 experienced surgeons (more than 50 laparoscopic surgeries) took part in this study. All participants were right-handed. The subjects performed 3 repetitions of a cutting task on synthetic tissue with the right hand, dissection of a gastric serous layer, and a suturing task in the dissection previously done. Objective metrics such as time, path length, speed of movements, acceleration and motion smoothness were analyzed for the instruments of each hand.Results
In the cutting task, experienced surgeons show less acceleration (P=.014) and a smoother motion (P=.023) using the scissors. Regarding the dissection activity, experienced surgeons need less time (P=.006) and less length with both instruments (P=.006 for dissector and P=.01 for scissors). In the suturing task, experienced surgeons require less time (P=.037) and distance travelled (P=.041) by the dissector.Conclusions
This study shows the usefulness of the evaluation system for the cutting, dissecting, and suturing tasks. It represents a significant step in the development of advanced systems for training and assessment of surgical skills in laparoscopic surgery. 相似文献2.

Background
We present our initial experience with the laparoscopic BPD technique for super-obese patients. Recommended tips on the technique are summarized.Methods
A total of 35 super-obese patients were submitted to BPD by laparoscopy in November 2009 and June 2010 for the treatment of morbid obesity.Results
All operations were performed by laparoscopy with no need to convert to laparotomy. No mayor complications and mortality related to surgery were observed.Conclusion
The Scopinaro technique can be safely performed in super-obese patients by surgeons with special dedication for bariatric surgery and advanced skills in intracorporeal suturing and knot-tying. 相似文献5.

Objective
Laparoscopic surgery is a successful treatment option offering significant advantages to patients compared with open ventral hernia repair. A cost-benefit analysis was performed to compare the clinical results and economic costs of the open and laparoscopic techniques for anterior abdominal wall hernia repair, in order to determine the more efficient procedure.Material and methods
We performed a prospective study of 140 patients with primary and incisional hernia, and analyzed clinical data, morbidity, costs of surgery and hospital stay costs.Results
The cost of disposable surgical supplies was higher with laparoscopic repair but reduced the average length of stay (P < .001) and patient morbidity (P < .001). The total cost of the laparoscopic procedure was, therefore, less than initially estimated, yielding a savings of 1,260 € per patient (2,865 € vs. 4,125 €).Conclusions
Laparoscopic ventral hernia repair is associated with a reduced complication rate, a lower average length of stay and with lower total costs. Laparoscopic repair can save 1.260 € for each patient, and so this procedure should be considered a cost-effective approach. 相似文献6.
Surgical site infection (SSI) is associated with prolonged hospital stay, increased morbidity, mortality and sanitary costs, and reduced patients quality of life. Many hospitals have adopted guidelines of scientifically-validated processes for prevention of surgical site and central-line catheter infections and sepsis. Most of these guidelines have resulted in an improvement in postoperative results. A review of the best available evidence on these measures in abdominal surgery is presented. The best measures are: avoidance of hair removal from the surgical field, skin decontamination with alcoholic antiseptic, correct use of antibiotic prophylaxis (administration within 30-60 min before incision, use of 1st or 2nd generation cephalosporins, single preoperative dosis, dosage adjustments based on body weight and renal function, intraoperative re-dosing if the duration of the procedure exceeds 2 half-lives of the drug or there is excessive blood loss), prevention of hypothermia, control of perioperative glucose levels, avoid blood transfusion and restrict intraoperative liquid infusion. 相似文献

Introduction
Faecal incontinence is a high prevalence disease in the general population. The aims of this study were to analyse which severity grading systems of faecal incontinence are used in Spain and to find out if there are differences in their use among specialists who manage these patients.Material and methods
A postal questionnaire survey was sent to all hospitals of the National Health Service in Spain in order to study the attitudes and opinions of general surgery and gastroenterology specialists regarding the clinical evaluation of patients with faecal incontinence.Results
Ninety-nine questionnaires were returned fully completed (65 surgeons and 34 gastroenterologists). Only 41.8% of responders used a diary card systematically (46.8% surgeons vs. 32.3% gastroenterologists; p=0.05). The Wexner score is the most widely grading system used in clinical practice (85.8% surgeons vs. 50% gastroenterologists; p=0.01). The most relevant issues in the evaluation of these patients were considered: Type of faecal incontinence, frequency of leakage and quality of life. Finally, 85.5% of those questioned said that the universal acceptance of severity grading systems by all specialists would be an improvement, and 98.9% considered it useful to start a national plan of information regarding clinical evaluation of faecal incontinence in Spain.Conclusions
There is variability in how faecal incontinence is evaluated among specialists in Spain. 相似文献8.
Introduction
The aim of this study was to evaluate the prevalence, clinical characteristics and management of chronic venous disease (CVD) in patients seen at primary care clinicsPatients and methods
This cross-sectional study was carried-out in Spain by 999 primary care physicians. They recruited 20 consecutive patients who were attending their clinics for any reason except for a medical emergency. The following Information was collected: demographic data, CVD risk factors, physical examination, clinical characteristics of the CVD and how it was managed.Results
19,800 patients were included, predominantly women (63%), with a mean age of 53.7 ± 20 years. The prevalence of CVD (CEAP categories C1 to C6) was 48.5% (95% CI, 47.8 to 49.2), significantly higher in women (58.5%; 95% CI, 57.6 to 59.4) than in men (32.1%; 95% CI, 31.0 to 33.1). The greater the age the higher the prevalence and the more advanced the CVD. Ninety-nine percent of the patients required some form of treatment, with a greater proportion among women (72% vs. 39%, P<.0001). Sclerotherapy, endothermal ablation or surgery was required by 4% of the patients. Referral to the specialist was considered for 7% of the patients.Conclusion
Chronic venous disease is highly prevalent among patients seen at primary care clinics in Spain, especially in women and elderly patients. Referral to a specialist and/or the use of the more invasive treatment procedures is uncommon. 相似文献9.

Introduction
Prosthesis infection is an infrequent but important complication in abdominal wall surgery. The aim of this study is to evaluate the incidence and risk factors for the infection of the prosthesis after hernia repair, as well as the treatment to apply.Material and method
Between January 2002 and December 2006, we performed 1055 prosthetic hernia repairs: 761 inguinal hernias (72.1%), 74 umbilical hernias (7%) and 220 ventral hernias (20.9%). We prospectively analysed preoperative, intraoperative and postoperative variables, as well as the incidence of infection of surgical wound and of prosthesis. We used ASA classification for preoperative anaesthetic evaluation.Results
The overall percentage of infection of the prosthesis was 1.3%. Infection was observed in 11 repairs with polypropylene mesh (PPL), in 4 with PTFE mesh, and one case in combined mesh. Risk factors of mesh infection were: obesity (p=0.002), diabetes (p=0.020), the type of repair (p=0.047), emergency surgery (p=0.001), the type and size of mesh (p=0.003; p=0.007) and time of surgery >180 min (p<0.001). Seven of the 11 patients with infection of PPL prosthesis were resolved with conservative treatment, whereas all the cases with PTFE infection or mixed mesh needed removal to solve the problem.Conclusions
Several factors are involved in producing a prosthesis infection. Whereas antibiotic treatment and surgical drainage of the infection can be sufficient in most PPL mesh infection, PTFE prostheses need to be removed prematurely in order to halt the infection process. 相似文献10.

Introduction
Mechanical preparation of the colon (MPC) in colorectal surgery has been a dogma that has been questioned over the last few years. The objective of this study is to demonstrate that morbidity in scheduled colorectal surgery is the same or lower without MPC.Material and method
Patients subjected to scheduled left colon and rectal surgery with primary anastomosis randomised into two groups. The “Preparation” group (MPC) received MPC and the “non-preparation” group (No-MPC) had only cleaning enemas. The variables collected were: demographic, oncological, nutritional, risk prediction models and morbidity-mortality.Results
Of the 193 patients included: 69 received MPC and 71 did not; 89 patients with colocolic anastomosis (MPC, 38; no MPC, 51) and 50 colorectal (MPC, 31; no MPC, 19). Statistically significant differences were seen in the overall analysis in favour of “no preparation” as regards morbidity (43.55 % with MPC and 27% with No MPC) and nosocomial infection (27.5% and 11.4%). There was 11.6% wound infections in the MPC compared to 5.7% in the no MPC, which was not statistically significant. The only mortalities were in the MPC group 2/69 (2.9% of patients). As regards the location of the anastomosis, in the colocolics the differences were more pronounced, with statistically significant differences in the morbidity, anastomosis dehiscence, and nosocomial infection variables. The effect of no MPC was not so evident in colorectal anastomosis.Conclusions
Our results suggest that there is no benefit in MPC before surgery in colocolic anastomosis. No-MPC is not associated with a higher morbidity in wound infection or anastomotic dehiscence. In colorectal anastomosis the differences are not so evident, therefore a much bigger series needs to be studied. 相似文献11.

Introduction
Laparotomy is the standard approach for the surgical treatment of acute small bowel obstruction (ASBO).Patients and methods
From February 2007 to May 2012 we prospectively recorded all patients operated by laparoscopy in our hospital because of ASBO due to adhesions (27 cases) and/or internal hernia (6 cases). A preoperative abdominal CT was performed in all cases. Patients suffering from peritonitis and/or sepsis were excluded from the laparoscopic approach. It was decided to convert to laparotomy if intestinal resection was required.Results
The mean age of the 33 patients who underwent surgery was 61.1 ± 17.6 years. 64% had previous history of abdominal surgery. 72% of the cases were operated by surgeons highly skilled in laparoscopy. Conversion rate was 21%. Operative time and postoperative length of stay were 83 ± 44 min. and 7.8 ± 11.2 days, respectively. Operative time (72 ± 30 vs 123 ± 63 min.), tolerance to oral intake (1.8 ± 0.9 vs 5.7 ± 3.3 days) and length of postoperative stay (4.7 ± 2.5 vs 19.4 ± 21 days) were significantly lower in the laparoscopy group compared with the conversion group, although converted patients had greater clinical severity (2 bowel resections). There were two severe complications (Clavien-Dindo III and V) in the conversion group.Conclusions
In selected cases of ASBO caused by adhesions and internal hernias and when performed by surgeons highly skilled in laparoscopy, a laparoscopic approach has a high probability of success (low conversion rate, short hospital length of stay and low morbidity); its use would be fully justified in these cases. 相似文献12.
Objective
To assess whether preoperative transarterial chemoembolisation (TACE) reduces haemorrhage during laparoscopic resection, thus making the Pringle manoeuvre unnecessary and avoiding any subsequent complications.Patients and methods
We present 3 cirrhotic Child A patients with early hepatocellular carcinoma, all of whom had been given the same treatment involving resection by laparoscopy and preoperative TACE of the segments to remove. All the nodules were located in the right hepatic lobe. One case was treated using total laparoscopic surgery and the two remaining cases were converted to the hand-assisted technique. In the first case we carried out bisegmentectomy VI-VII; in the second, segmentectomy VI plus radiofrequency of a second nodule in segment VII, and in the third case, segmentectomy V.Results
There was no morbidity or mortality. Blood transfusion was not required by any of the patients; in fact blood losses were 100, 50 and 150 ml, respectively, and it was not necessary to carry out the Pringle manoeuvre. Surgical margin was greater than 1 cm in the three cases and hospital stay was less than 3, 3 and 4 days, respectively.Conclusion
TACE prior to early hepatocellular carcinoma resection in cirrhotic patients seems to improve surgical safety with low blood losses without the use of the Pringle manoeuvre. Prospective random studies should be carried out on a larger number of patients in order to assess this technique. 相似文献13.

Introduction
Laparoscopic Heller myotomy has become the gold standard procedure for patients with achalasia. This study evaluates the clinical status, quality of life, and functional outcomes after laparoscopic Heller myotomy.Material and methods
We analyzed patients who underwent laparoscopic Heller myotomy with an associated anti-reflux procedure from October 1998 to December 2010. Before surgery, we administered a clinical questionnaire and as of 2002, we also evaluated quality of life using a specific questionnaire (GIQLI). In 2011, we performed a follow up for all available patients. We administered the same clinical questionnaire and quality of life test as before surgery and performed manometry and 24-hour pH monitoring. According to the length of follow up, patients were divided into 3 groups. Group 1 with a follow-up between 6 and 47 months; group 2 follow-up between 48 and 119 months, and group 3 with a follow-up of more than 120 months). Moreover, 27 patients had already been evaluated with this same protocol in 2003. Pre- and postoperative data were compared for the 3 groups and for patients who completed follow up in 2003 and 2011.Results
Ninety-five patients underwent laparoscopic Heller myotomy. Seventy-six (80%) were available for follow-up. Mean follow-up was 56 months (range 6-143). Global improvement in dysphagia was 89%. Total DeMeester score decreased in the 3 groups. GIQLI scores improved after surgery, reaching normal values. Manometric determinations showed normal LES pressures after myotomy in the 3 groups. Ten percent of overall 24-hour pH monitoring was abnormal. The group of patients followed up in 2003 and in 2011 showed no impairment in the variables studied in the long term.Conclusions
Long-term follow up of the laparoscopic approach to achalasia showed good results concerning clinical status and quality of life, with normal sphincteric pressures and a low incidence of gastroesophageal reflux. 相似文献14.

ALPPS (associating liver partition and portal vein ligation for staged hepatectomy), in 2-stage liver resections, achieves hypertrophy of the functional liver remnant (FLR) in 7 days, and the objective of this technique is the occlusion of the intrahepatic collaterals. In March 2012 we published a new surgical technique associating the insertion of a tourniquet in Cantlie’ line and right portal vein ligation (ALTPS: Associating liver tourniquet and right portal vein occlusion for staged hepatectomy). In this paper we present this ALTPS technique placing the tourniquet in the umbilical fissure to obtain hypertrophy of segments II-III. It was performed in a 51 year-old patient with a recurrent right renal hypernephroma which involved all the anatomic right lobe and inferior vena cava. Preoperative FLR was 380 ml (20% of the total volume) increasing 150% at 7 days (to 953 ml, 31% of the total). In the second step, we performed a right trisectionectomy and retrohepatic inferior vena cava resection, replacing it by a 2 cm-ring goretex graft. 相似文献

Introduction
The rapid development of laparoscopic surgery makes resident training programmes necessary.Objective
To analyse the results of a structured programme of laparoscopic training in an experimental laboratory.Material and method
From 2003 until 2007, we trained 11 general surgery residents for 20 h every 3 months, for three years. The practice consisted of suture and anastomosis in Endo-Trainer with animal organs, as well as laparoscopic techniques in live animals. In the Endo-Trainer practice we evaluated the time and quality of anastomosis performance. In laparoscopic techniques (cholecystectomy and anti-reflux surgery) a task table was evaluated, from 0 (no errors) to 100 (severe lesion).Results
In total, 314 anastomosis were performed by the 11 residents, with a median of 28.5 per resident (24-42). The mean time for the first gastro-jejunal anastomosis was 135 min (100-140) and 65 min (57.5-105) for the first jejunal-jejunal anastomosis. Maximum learning was achieved after 45 training hours. There wer no appreciable ifferences between both types of anastomosis. There was inadequate anastomosis quality due to leakage in 17.1% during the learning period and 13.7% during the consolidation period. In the animal, 172 procedures were performed. In cholecystectomy and anti-reflux surgery the mean scores were 2.4 and 5.6 points, respectively. In the remaining procedures, subjectively evaluated by the monitors, the quality was adequate in 65%, deficient in 22% and highly deficient in 13%.Conclusions
This structured programme of laparoscopic skills based on intestinal anastomosis allows for quicker resident training. 相似文献16.

Aim
The continual advances in our knowledge of the pathogenesis and hormonal disorders of morbid obesity lead to new studies in experimental animals and the development of new technical options. The aim is to asses whether ileal transposition can be a good treatment of morbid obesity associated with diabetes mellitus due to the action of intestinal peptide Glp-1 (enteroglucagon) compared to gastric bypass and vertical gastroplasty (VGB).Material and methods
Trial enviroment: experimental animals ZDF rats (Zucker Diabetic Fatty rats). Subjects of the study: three groups of 10 animals each one divided as: a) ileal tranposition; b) gastro-jejunal bypass; c) vertical gastroplasty. Parameters to determine: weight loss, levels of glycaemia, enteroglucagon, insulin and ghrelin in blood, one week before the operation as a baseline control, and 15 days after the surgical procedure.Results
Gastrojejunal bypass produces the most significant weight loss. There is a significant decrease in intake in all groups. Hyperinsulinaemia and hyperglycaemia tend to decrease after surgery in all groups, but in ileal transposition there is better control of ketosis. After gastrojejunal bypass and ileal transposition, we observed an increase in GLP-1 levels but were only significant in ileal transposition.Conclusions
Ileal transposition produces a decrease in plasma glucose and better control of diabetes mellitus, which could benefit patients affected by morbid obesity and poor metabolic control. More studies are needed on other models of obesity. A model of exogenous and reversible obesity could be a good option to study the real benefits of the interventions. 相似文献18.
