Purpose
To evaluate the usefulness of hydrogen peroxide-enhanced ultrasound (H2O2) in the preoperative assessment of perianal fistulas and to compare these results with unenhanced ultrasound findings.Methods
All patients with surgically confirmed perianal fistula who underwent preoperative enhanced and unenhanced ultrasound were included. We compared enhanced and unenhanced ultrasound findings with surgical results (χ2 and McNemar tests).Results
A total of 44 surgically treated patients were analysed. Hydrogen peroxide-enhanced ultrasound correctly identified primary fistula tracks in 34 patients (sensitivity of 77%), 100% of abscesses and the internal opening in 29 out of 37 identified with surgery (sensitivity of 78% and specificity of 70%). The use of hydrogen peroxide provided additional information to the ultrasound performed without the use of contrast enhancement in 32 of the 44 patients (73%). H2O2 increased the number of fistula tracts correctly detected (77% vs 45%; p<0.003), particularly suprasphincteric fistulas, as well as internal openings (78% vs 22%; p<0.001) and secondary tracks (70% vs 0%). Additional detection of fistula tracks after H2O2 injection was higher in patients with previous surgery (68% vs 35%; p<0.05).Conclusions
Hydrogen peroxide-enhanced ultrasound shows good agreement compared with surgical findings in the assessment of perianal fistulas. H2O2 improves conventional ultrasound results, increasing the detection of fistula tracks and internal openings, and also providing additional information, particularly in previously operated patients. 相似文献2.

Objective
Negative pressure therapy (VAC, vacuum assisted closure) is a method used still in our country. It consists of a system of aspirating a wound by means of a piece of foam and a few adhesive films. It allows the treatment of complex wounds, included (although this is still controversial) those with intestinal fistulas. We present 3 cases of treatment with VAC in this situation and a review of the published literature.Patients and method
We have treated 10 patients, since VAC therapy was introduced into our centre of which 3 of whom had a fistula in the bed of the surgical wound. We describe the clinical information of the patients and the therapy that followed in each of the cases.Results
Significant local clinical improvement of the disease, with control of the symptoms, was achieved in all 3 cases. We were able to re-operate to close the fistula in one of the patients, with subsequent good progression of the wound. In the other two cases it gave them a better quality of life although both died due to the overall complexity of their situation.Conclusions
VAC therapy, although controversial in the treatment of intestinal fistulas, can help to improve the local situation of the wounds, the comfort of the patients and their general situation. 相似文献3.

Objective
The aim of this study was the prospective evaluation of the functional results of a series endorectal advancement flaps in the treatment of complex anal fistulas.Material and methods
A total of 90 patients were operated on for a complex anal fistula by means of fistulectomy and endorectal advancement flap. The functional results were evaluated using the Wexner continence scale and an anorectal manometry study before and after surgery.Results
There were seven patients with fistula recurrence (7.7%) and the same surgical procedure was performed on five of them, resulting in healing in all cases. Significant reductions in maximum resting pressure (83.85±30.96 vs 46.51±18.67; p<0.001) and maximum squeeze pressure (220.97±100.21 vs 183.06±75.36; p<0.001) were seen 3 months after surgery. On the continence scale, 80% of patients had a normal continence with a value of 0 on thepostoperative Wexner scale, while 20% recorded changes in continence values, most of them lower than 3 points.Conclusions
Endorectal advancement flap is an effective surgical procedure in complex anal fistulas treatment, with a low recurrence rate. Only 20% of the patients showed changes in the continence value. 相似文献4.

Introduction
The main aim of the study was to apply a severity classification of sphincter lesions detected by endoanal ultrasound using Starck score in patients who suffered faecal incontinence.Material and method
Data were analysed on 133 patients with faecal incontinence. Those in whom anal sphincter lesions were detected by endoanal ultrasound are described and their corresponding scores according to Starck classification calculated. This system scores severity of detected sphincter lesions from 0 to 16, involving the three axes of the anal canal. Patient demographic characteristics and anorectal manometry results were also analysed. The relationship between this score, patient gender and age, and anorectal manometric results were also analysed.Results
A total of 83 (62.4%) patients had some type of anal sphincter lesion. The presence of sphincter defects was not related to gender (P=0.172), although it did correlate with younger ages (P=0.028). The severity of anal sphincter damage by Starck score did not show significant correlation to gender (P=0.327) or to the age (P=0.350) of patients. However, a significant correlation was detected between Starck score and anal resting pressure (P=0.008) or anorectal squeeze pressure (P=0.011).Conclusions
The presence of anal sphincter injuries could be well defined by Starck score in patients with faecal incontinence. Severity of damage scored by Starck correlated with anorectal manometric results. 相似文献5.

Introduction
Caecal volvulus is the second most frequent location of colonic volvulus after sigmoid colon. It usually shows up as bowel obstruction.Material y method
We review our experience of 18 cases of cecal volvulus treated in our centre between 1987 and 2007.Results
We studied 8 males (44.4%) and 10 females (55.6%), with a mean age of 63.3 years. As an associated factor it was noted that 10 patients (55.6%) were bedridden. The most common clinical signs were abdominal distensión and tenderness, constipation and vomiting. Simple abdominal X-rays have a low diagnostic accuracy, though they reveal a bowel obstruction. Only 1 patient underwent elective surgery. In 10 patients (55.6%) a right hemicolectomy was performed, in 3 (16.8%) cecostomy, in 3 cecopexy and in 2 (11.2%) devolvulation only. There were complications in 3 patients (16.8%), 2 prolonged ileus and 1 wound infection. There were no recurrences.Conclusions
Caecal volvulus is an emergency pathology, requiring surgical treatment. Right hemicolectomy is the treatment of choice both in viable and gangrenous colon. Caecostomy is an alternative treatment in the high risk patient with a viable colon. 相似文献6.

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7.

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8.

Aim
Assess the postoperative morbidity rates in pancreatic resection.Material and method
Prospective observational study which includes 117 patients who underwent surgery consecutively due to pancreatic or periampullary tumours. In 61 of the patients, cephalic pancreatectomy was carried out; 15 underwent total pancreatectomy; one underwent enucleation and 40 underwent distal pancreatectomy.Results
Overall morbidity was 48.7% (59% for cephalic pancreatectomy, 35% for distal pancreatectomy and 46.7% for total pancreatectomy). The most frequent complications were intra-abdominal abscesses and collections (15.38%) and medical complications (13.68%). The incidence of pancreatic fistula was 9.83% for cephalic pancreatectomy and 10% for distal pancreatectomy. The reintervention incidence was 14.53%. Overall mortality was 5.12% (6.56% for cephalic pancreatectomy, 2.5% for distal pancreatectomy and 6.67% for total pancreatectomy). The presence of postoperative complications, the need for reintervention and the fact of being over 70 years of age correlated significantly with mortality.Discussion
Pancreatic resection has high morbidity rates. Mortality is low and is practically limited to patients older than 70 years. 相似文献9.
Introduction
Laparoscopy has been used for the treatment of anorectal malformations (ARMs) in an attempt to be less invasive and with the hope that it would result in a better functional outcome. There remains a significant debate about whether these expectations have been fulfilled.Methods
Seventeen patients with ARM for whom laparoscopy was used were retrospectively reviewed. Six were operated on primarily by the authors, and 11 cases were referred after a laparoscopic repair performed elsewhere. In addition, a literature review was performed looking for evidence of less invasiveness and improved functional results in patients operated on laparoscopically.Results
The diagnosis was imperforate anus with a rectobladder neck fistula in our 6 cases with the fistula ligated laparoscopically in each case. In 1 patient, the malformation was repaired entirely using laparoscopic technique. The other 5 patients had a laparoscopically assisted repair because we had to open the abdomen to taper a dilated rectum in 2, mobilize a very high rectum in 2, and take down a distal colostomy stoma in 1. Eleven patients were referred with a variety of problems after a laparoscopic repair done elsewhere for rectal stricture (5), rectal prolapse (4), recurrent rectourethral fistula (3), rectal mislocation (3), failed attempted repair leading to fecal incontinence (1), and a posterior urethral diverticulum (1). Our literature review included 47 references (involving 323 patients) published between 1998 and 2010. All studies showed that laparoscopic repair of ARMs is feasible. The review, however, did not provide evidence of less invasiveness or improved functional results.Conclusions
Laparoscopy for ARM is a less invasive procedure when compared with those operations that would have previously required a laparotomy (rectobladder neck fistula). In cases of rectoprostatic fistulae, the laparoscopic approach is feasible and avoids a lengthy posterior sagittal incision. There is no evidence that the laparoscopic approach is a less invasive procedure for other types of ARMs. In cases of rectobulbar fistula, congenital anal stenosis, perineal fistula, ARM without fistula, the evidence suggests that it may be lead to more complications. There is no evidence in the literature demonstrating better functional results in cases of ARM operated on laparoscopically. 相似文献10.

Introduction
The new methods of teaching, based on new technologies, already available in other educational and professional fields are gradually being introduced in our Medical Schools. The aim of our study is to present our initial experience in the introduction of a subject on the principles of surgery in our university.Material and methods
The subject was offered voluntary to undergraduate students, with a maximum of 65 students per course during two consecutive academic years, while maintaining the traditional teaching with a formal lecture program with a different lecturer. The subject was designed with 60% virtuality on a WebCT platform and later in Moodle. The virtual subject was structured into teaching units, academically directed activities and communication tools. The subject was assessed in a report prepared by Cadiz University Department of Evaluation and Quality.Results
There were 32 students in the 2005-2006 course and 62 in the following course. The mean activity of the students was: 602 accesses, 13 subjects for discussion forums and 20 e-mails between students and teachers. The students who participated in the Virtual subject have remarked that virtualisation make it more attractive and is an aid in the acquisition of knowledge. The data obtained from the report showed better results than the mean obtained in other subjects of the Department, School of Medicine and Cadiz University.Conclusions
The virtual subject of principles of surgery has been well evaluated in our university campus. We believe that the provision of teaching tools and new communication models make an effective contribution to the teaching of surgery as a subject in the school of medicine curriculum. 相似文献11.

Background
The frequency of bowel and mesenteric injuries is increasing. They are difficult to diagnose and delays in their diagnosis leads to a significantly increased morbidity and mortality. The aim of this study is to evaluate the usefulness of the computed tomography (CT) in the detection of blunt bowel and mesenteric injuries.Method
Between January 2000 and October 2007, 79 patients with blunt abdominal trauma (60 men and 19 women) were included in our study. They underwent laparotomy after performing the abdominal CT. The CT findings were compared with the findings at laparotomy in order to determine the accuracy of the CT in the detection of bowel and mesenteric injuries.Results
For the detection of bowel and mesenteric injuries we obtained for the CT: Sensitivity=84.2%, Specificity=75.6%, Positive Predictive Value =76.2%, Negative Predictive Value =83.8%, Positive Probability Value=3.45 and Negative Probability Value =0.21. Accuracy: 79.7%.Conclusion
The abdominal CT is suitable for detecting bowel and mesenteric injuries following blunt abdominal trauma. 相似文献12.
Introduction
We present a non-randomised comparative study of two patients series followed up prospectively, in which convention laparoscopic cholecystectomy is compared with transvaginal cholecystectomy, a hybrid transluminal endoscopic procedure, with the objective of assessing the clinical safety of the procedures and its efficacy in the resolution of cholelithiasis.Patients and method
A non-randomised prospective clinical series of 40 female patients, operated on for cholelithiasis using endoscopic surgery, 20 with a conventional laparoscopic approach and 20 using a transvaginal endoscopic approach. Surgical wound infection, urinary infection, evisceration, eventration, mortality and other complications.Results
Scheduled operations were performed on the 40 patients as indicated. There were no complications during the operations. There was no mortality associated with the procedures and there was only one post-surgical complication, a urinary tract infection in one patient operated on by the transvaginal approach. The mean follow up was the same in both groups (9 months). The mean hospital stay was less than 0.8 days in both groups. The duration of the surgery was longer in the transvaginal approach group, with a mean of 69.5 min, compared to 46.2 min in the laparoscopy group.Conclusions
Although the cosmetic benefit is obvious, no differences were found as regards parietal problems in this series. The duration of the transvaginal surgery is higher than that of the transparietal, but the times of both are acceptable. In this study, the non-inferiority in the safety and efficacy of the transvaginal approach is able to be assessed. 相似文献13.

Introduction
The objective of this study is to assess whether the results of loop ileostomy closure in terms of morbidity and hospital stay are influenced by the type of anastomosis and suture used.Method
All patients who underwent loop ileostomy closure were reviewed. A retrospective cohort study comparing morbidity and hospital stay according to the type of anastomosis (TT/LL) and the type of suture (hand sewn/mechanical) was performed.Results
From January 2003 to November 2011 a total of 167 loop ileostomy closures were analized. The groups were: type of anastomosis (TT 95/LL 72) and type of suture (manual 105/stapled 62). In 76% of the observed population the underlying disease was cancer. Mortality occurred in one case. The stratified morbidity analysis by type of complications showed no significant differences between the groups in terms of local (7.4% TT, LL 8.3%, 6.7% hand sewn, stapled 9.7%), general (TT 9.5%, 16.7% LL, hand sewn 6.7%, 6.5% stapled) and surgical (TT 15.8%, 19.4% LL, hand sewn 17.1%, 17.7% stapled) complications, nor in the rate of reoperations (TT 6.3%, 6.9% LL, hand sewn 6.7%, 6.5% stapled) and hospital stay in days (TT 7.8, 8 LL, hand sewn 8.6, stapled 6.7)Conclusions
Closure of loop ileostomy can be performed regardless of the type of suture or anastomosis used, with the same rate of morbidity and hospital stay. 相似文献14.
Background
The incidence of neoplastic diseases is higher in patients undergoing solid organ transplant. However, the incidence of bronchogenic carcinoma (BC) is controversial. The objective of our study was to determine the incidence of BC in a large cohort of transplant patients and the role of surgery.Material and methods
Until December 2006, 3596 patients underwent solid organ transplant at our institution; 24 (0.7%) patients subsequently developed BC, of which 6 (24%) were classified as clinical stage I and submitted to surgical treatment. Survival was estimated by the Kaplan-Meier method.Results
Three patients received a liver transplant, two a kidney transplant and one a heart transplant. All were male and all had a smoking history. Mean age was 58.6 years. Two patients had cough, one accompanied by bloody expectoration, and BC was an incidental finding in the remaining cases. The interval between transplant and diagnosis of BC was 38.1 months. Epidermoid carcinoma was the most frequent histological type. Mean tumour size was 3.6 cm (range, 1.3-6). One tumour was classified as pathological stage IA, four as stage IB and one as IIB due to parietal pleural invasion. No patient died during the perioperative period and only one had a haemothorax which resolved with chest tube drainage. Mean hospital stay was 8.5 days (range, 7-11). The immunosuppression regimen was maintained continuously. In subsequent follow-up, one patient died from BC metastasis, one from sepsis, one from chronic renal failure, and three remained alive. The probability of survival at 5 years was 40%, and median survival was established at 5 years.Conclusions
The incidence of BC in patients undergoing solid organ transplant and the proportion of patients diagnosed in early stages does not differ from non-transplant patients diagnosed with BC, which questions the role of immunosuppression in the genesis and aggressiveness of BC in transplant patients. Surgery may offer acceptable results in early stages, with acceptable rates of perioperative morbidity and mortality. 相似文献15.

Objectives
To assess the management of gallbladder cancer (GBC) in our region.Material and methods
Data on 372 patients who underwent cholecystectomy were identified from our database (January 2003 to February 2008) and 6 patients were found to have GBC.Results
Four patients had incidental carcinoma, one case was preoperatively suspected, and one patient presented with jaundice and locally advanced neoplasia. The incidence was 2 per 100,000 inhabitants per year; incidental carcinoma in 1.1% of cholecystecomies. The ultrasonography showed multilithiasis in 2 patients, sludge and neoplasia in 1, gallstones more than 3 cm in 2, and tumor mass only in 1 case. T stage: 1 case of T0 (in situ), 1 of T1, 2 of T2 and one T4. Incidental carcinomas were reoperated on when a T2 was established: 2 underwent lymphadenectomy and cystic stump resection, 1 segmentectomy IVb-V and lymphadenectomy. In the preoperative suspected neoplasia a cholecystectomy, lymphadenectomy, and partial hepatic gallbladder bed resection was initially performed.Conclusions
GBC has a low incidence but it will be found in 1% of cholecystectomies. There is no adjuvant treatment and T-based surgical treatment is the is the only opportunity to reach cure in those patients. A national GBC database would be helpful in the publication of national guidelines for this disease. 相似文献16.

Introduction
The increasing aging of the population also increases the prevalence of symptomatic gallbladder diseases. It is important to analyse their surgical treatment in the elderly.Methods
All the laparoscopic cholecystectomies performed in our surgery department on patients aged 80 years-old or over from 1992 to 2007 were included in this study.Results
Laparoscopic cholecystectomy was performed on 133 patients 80 years-old and over, with 63% of them women, and an average age of 83.23 years. Biliary colic (29%) and acute pancreatitis (44%) were the main reasons for surgery. Associated diseases were found in 73% of them. Only 7.5% needed urgent surgery, even although 71% were admitted urgently. There were 13.5% conversions to open surgery, 17% morbidity and 2.3% mortality.Conclusions
Laparoscopic cholecystectomy can be recommended in symptomatic gallbladder disease in the elderly. 相似文献17.
Background
The aim of this study was to evaluate whether the use of fibrin glue as a sealant over an anastomosis is a risk factor for anastomotic leakage after laparoscopic rectal cancer surgery.Methods
Prospective data were collected from 223 patients with rectal cancer who underwent laparoscopic resection without defunctioning stoma.Results
A total of 104 patients underwent laparoscopic rectal resection, followed by the application of fibrin glue over the stapled anastomosis, while 119 underwent surgery alone. No difference in clinically significant leakage was observed between the fibrin and the nonfibrin groups (5.8% vs 10.9%, P = .169). In multivariate analysis, extraperitoneal tumor location and operation duration >220 minutes were independently associated with anastomotic leakage.Conclusions
Significant predictors of anastomotic leakage include extraperitoneal tumor location and operation length >220 minutes. Fibrin glue application over the stapled anastomosis was not found to be significantly associated with anastomotic leakage. 相似文献18.

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19.

Introduction
The current surgical scenario of the surgery through natural orifices or «no-scar surgery» requires acquiring new technical skills by the surgeon. We introduce the initial experience of the Minimally Invasive Surgery Centre Jesús Usón (MISCJU) in the design and setting-up of a surgical training programme using the the natural orifices approach for the acquisition of surgical skills and abilities, based on the preliminary trials in simulators and a pig model.Material and methods
After initial training, using a laparoscopic pelvic-trainer, 7 female pigs, with weights between 35-40 kg, were operated on. The transvaginal approach was completed using a one-channel gastroscope in all the animals. After accessing the abdomen, the abdominal cavity was explored, and the surgery was concluded with the endoscopic cholecystectomy.Results
Endoscopic cholecystectomy was successfully completed in 6 cases. In one of the animals, the procedure was stopped because of technical problems regarding the endoscope leaning to one end. The average surgical time was 107.14 min (range, 80-150 min). The transvaginal approach enabled the abdominal to be explored and the dissection, ligature and section of the cystic duct and the cystic artery. After cholecystectomy, the gallbladder was extracted through the vagina. After the procedure necropsy did not reveal intra-abdominal lesions or intraoperative complications.Conclusions
The pure transvaginal cholecystectomy is a feasible and reproducible procedure in the animal model. A systematized training model, which includes physiopathology knowledge as well as technical knowledge, in order to translate these procedures to the clinical practice in a safe way, is needed. 相似文献20.
