RESUMEN
PURPOSE: Inguinal hernia repair is one of the most performed procedure all over the world with more than 20 million procedures performed each year. Due to the lack of data in literature about the learning curve of the Lichtenstein procedure, we decided to reproduce a research on learning curves with the same methodology proposed in our previous study about laparoscopic hernia repair. The aim of this multicentre study was to analyse how many cases are required to achieve the learning curve for a Lichtenstein procedure. METHODS: We performed a retrospective analysis of the first 100 Lichtenstein procedures performed by 4 trainees from three different institutions and compared them with the same number of procedures performed by 3 senior surgeons from the same institutions. The data about the achieving of learning curve were evaluated with CUSUM and KPSS test. RESULTS: No differences about biometrical features were found between the seven groups of patients. CUSUM analysis showed that the trainees achieve the learning curve after 37-42 procedures, reaching an operative time similar to that one of the senior surgeons. CONCLUSIONS: In conclusion, we have shown that the number of procedures required to reach the learning curve from the beginning of surgical residency is around 40 hernia repairs. This number, produced in a controlled environment under strict supervision, could be the minimum requirement to start the procedure of accreditation and specialization in hernia surgery and is higher and steeper than previously reported.

PURPOSE: Primary (PVHs) and incisional (IHs) ventral hernias represent a common indication for surgery. Nevertheless, most of the papers presented in literature analyze both types of defect together, thus potentially introducing a bias in the results of interpretation. The purpose of this systematic review and meta-analysis is to highlight the differences between these two entities. METHODS: Methods MEDLINE, Scopus, and Web of Science databases were reviewed to identify studies evaluating the outcomes of both open and laparoscopic repair with mesh of PVHs vs IHs. Search was restricted to English language literature. Risk of bias was assessed with MINORS score. Primary outcome was recurrence, and secondary outcomes were baseline characteristics and intraoperative and postoperative data. Fixed effects model was used unless significant heterogeneity, assessed with the Higgins I square (I2), was encountered. RESULTS: The search resulted in 783 hits, after screening; 11 retrospective trials were selected including 38,727 patients. Mean MINORS of included trials was 15.2 (range 5-21). The estimated pooled proportion difference for recurrence was - 0.09 (- 0.11; - 0.07) between the two groups in favor of the PVH group. On metanalysis, PVHs were smaller in area and diameters, affected younger and less comorbid patients, and were more frequently singular; the operative time and length of stay was quicker. Other complications did not differ significantly. CONCLUSION: Our paper supports the hypothesis that PVH and IH are different conditions with the latter being more challenging to treat. Accordingly, EHS classifications should be adopted systematically as well as pooling data analysis should be no longer performed in clinical trials.

INTRODUCTION: Lymphoscintigraphy is the gold standard for imaging in the diagnosis of peripheral lymphedema. However, there are no clear guidelines to standardize usage across centers, and as such, large variability exists. The aim of this perspectives paper is to draw upon the knowledge and extensive experience of lymphoscintigraphy here in Genoa, Italy, from our center of excellence in the assessment and treatment of lymphatic disorders for over 30 years to provide general guidelines for nuclear medicine specialists. METHOD: The authors describe the technical characteristics of lymphoscintigraphy in patients with limb swelling. Radioactive tracers, dosage, administration sites, and the rationale for a two-compartment protocol with the inclusion of subfascial lymphatic vessels are all given in detail. RESULTS: Examples of lymphoscintigraphic investigations with various subgroups of patients are discussed. The concept of a transport index (TI) for semi-quantitative analysis of normal/pathological lymphatic flow is introduced. Different concepts of injection techniques are outlined. DISCUSSION: It is past time that lymphoscintigraphy in the diagnosis of lymphatic disorders becomes standardized. This represents our first attempt to outline a clear protocol and delineate the relevant points for lymphoscintigraphy in this patient population.
RESUMEN
Inflammatory bowel disease (IBD), Crohn's Disease (CD) and Ulcerative Colitis (UC) are associated with an increased risk of arterial and venous thromboembolism. A 2 to 3 time fold increased risk of developing thromboembolic complications was reported for IBD patients compared to general population. A systematic literature search was conducted using PubMed, Medline, Scopus, Cochrane database. The key words were: "Inflammatory Bowell Disease", "Crohn's Disease and Thrombosis", "Ulcerative Colitis and Thrombosis", "Thrombosis" and "Inflammatory Bowel Diseases and Thrombosis". Full articles and abstracts were included. Studies such as case reports, letters and commentaries were excluded from the analysis if appropriate data could not be extracted. Although no randomized controlled trials (RCTs) have been established to evaluate the efficacy of thromboprophylaxis in patients with IBD due to the incidence of VTE and PE in such patients, it is highly recommended the adoption of thromboprophylactic measures. Available prophylaxis and treatment options include pharmacological anticoagulant therapy (LMWH-Low Molecular Weight Heparin, Fondaparinux and UH-Unfractionated Heparin) and mechanical prophylaxis. In case of acute VTE patient must be treated with fibrinolytic agents and in selected non-responsive cases vascular surgery. IBD patients have an increased risk of VTE complications. Prophylaxis for VTE should be recommended in all patients who do not show contraindications to treatment.

AIM: The SECCA system is a treatment option for patients with faecal incontinence and was introduced into clinical practice in 2002. Clinical studies of radiofrequency energy to treat patients with faecal incontinence have been published. This article aimed to review all published series to assess the results of this treatment. METHOD: Twelve studies were included. Outcomes analysed included quality of life, the Wexner incontinence score, anorectal manometry and endoanal ultrasound findings. RESULTS: A total of 220 patients from 10 studies were included. In the majority of clinical studies, the SECCA procedure has been shown to be an effective treatment of mild-to-moderate faecal incontinence. CONCLUSION: When patient selection is appropriate, this treatment has demonstrated clinically significant improvements in symptoms, as demonstrated by statistically significant reductions in the Wexner incontinence and quality of life scores.

Three cases of carcinoid tumour of the appendix (about 0,3 % of all performed appendectomies) has induced the Authors to a review of the literature with the aim to underline the most important biological and pathological findings and the current clinic and therapeutic knowledges. The diagnosis before surgery is rarely made; it is formulated incidentally in most patients by the histological exam during the operation for an appendicitis or during other surgical procedures. The kind of surgical intervention, that is the entity of the surgical demolition, for the treatment of the carcinoid tumours of the appendix is still controversial: appendectomy or right colectomy? It is possible identify, also during the operation for an appendicitis or for other abdominal lesions, criteria that can orient toward a major surgery (size of the neoplasia, subserosal lymphatic invasion, infiltration of the serosa, diffusion in the meso-appendix, location in closeness of the base of the appendix, invasion of the the locoregional lymph nodes, presence of metastases, section ?margins, number of mitoses, cellular pleiomorfism).

The ageing process of general population implies new socio-sanitary problems. Indications for surgical intervention have been modified and enhanced. As far as elective surgery is concerned, the results in elderly subjects do not seem alarming, whereas less satisfactory results have been registered in the patients who underwent an emergency surgical intervention, where nowadays morbidity and mortality still turn out to be high. The Authors have reported their experience of emergency surgery in the geriatric patient. From 1982 to 2002, 718 pts (361 males, 50.3% and 357 females, 49.7%; average age 50 yrs, range 5-92) underwent emergency surgical interventions for abdominal lesions. The pts were subdivided in two groups: group A (> 65 years; 190 pts, 87 males and 103 females; average age 72 yrs, range 66-92); control group B (<65 years; 528 pts, 274 males and 254 females; average age 43 yrs, range 5-65). The results were assessed in terms of morbidity and of the operative and post-operative mortality. Postoperative morbidity proved to be equal to 25.7% (36.3% in the group A, 21.9% in the group B), while intraoperative mortality equal to 0.27%. Postoperative mortality resulted equal to 12.1% (significantly higher in group A pts -- 16.8%- than in group B pts --10.4%). The mortality of the 190 pts belonging to group A was higher in the pts which were presenting respectively 1, 2, 3 or more concomitant diseases. The progressive percentage increase in the number of interventions on elderly pts not only can be due to the demographic increase of old people, but it can also be linked to a change in the surgeon's attitude. At the present time, while elective geriatric surgery implies an acceptable mortality rate (5-8 %), emergency geriatric surgery has not notably modified the prognosis in the last decades and mortality has turned out to be still high (20-30%). We think that it will be possible to obtain better results through geriatric surgery only by reducing emergency interventions as much as possible. In order to do so, it will be important to insist on intervening before the illness, during its natural evolution, requires actions which cannot be postponed. This would lead to positive results not only in terms of mortality and morbidity, which are still considered as the main targets, but also as far as the period of the stay in hospital and costs are concerned.

Thirty-five patients with Crohn's Disease (CD) were observed: 18 have been treated with medical therapy and 17 (48.6%) underwent to surgical treatment : 1) intolerance to the medical treatment in 5.9% (1 case); 2) local complications in 94.1% (16 cases: 6 stenosis, 2 occlusions, 3 abscesses, 3 fistulas, 1 perforation with peritonitis, 1 case toxic megacolon). The operations have been 19: resective interventions 14 (bowel and/or colon resections), conservative interventions 5. The mortality was 0, the morbidity 35,29%. The incidence of the recurrences in a follow up of 5 year was 42,9%. The Authors conclude that the surgery, indicated for the treatment of complications, can be resective surgery (perforating Crohn disease: fistulas, abscess) or conservative surgery (stenosing Crohn disease: stenosis). Recently the conservative intervention are proposed in the treatment of fistulas and abscesses too, but when the inflammation is mild and in patients that underwent to extensive intestinal resection with risk of short bowel syndrome.

We present a case of schwannoma of the neck in 49 year old man, symptomatic (paresthesia, cervical mass and dysphagia). After ultrasonography and magnetic resonance of the neck, the patient was operated and excision of the lesion was completely performed. The operation was performed through a cervical approach: the nerves and the vascular and muscular structures were carefully isolated and preserved. The tumour arised from the cervical sympathetic chain. The diagnosis of schwannoma was possible only by histopathologic examen. After 48 months no local recurrence or postoperative complication related to intervention were found. These lesions are uncommon. The identification of the nerve is often difficult until the operation, which is the treatment of choice for the schwannoma.

We studied the role of telecardiology in reducing unnecessary hospital admissions of patients with suspected life-threatening cardiac events (CEs), evaluated by general practitioners (GPs). Over one month, 456 consecutive patients (mean age 65 years, SD 19) complaining of typical (10%) or atypical (42%) chest pain, palpitations (19%), dyspnoea (19%) or syncope (10%) were enrolled. Before teleconsultation, the GPs recorded their own opinion (based on clinical evaluation only) about the presence of a CE. Following transmission of the electrocardiogram (ECG), this opinion was compared with that of the cardiologist. In total there was agreement between the GP and cardiologist about the presence of a CE in 316 of the patients (69%) and disagreement in 140 patients (31%). This represents a specificity and sensitivity of the GPs' diagnosis of 76% and 47%, respectively. For 84 of 134 patients judged as having a CE by the GP, telecardiology avoided hospitalization; on the other hand, telecardiology identified a CE in 56 of 322 patients judged as not having a CE by the GP. Telecardiology is a useful tool with which to reduce unnecessary hospitalizations in patients with suspected life-threatening CEs.

PURPOSE: Sacral nerve modulation appears to offer a valid treatment option for some patients with fecal incontinence and functional defects of the internal anal sphincter or of the striated muscle. METHODS: Sixteen patients with fecal incontinence (4 males; mean age, 51.4 (range, 27-79) years) with intact or surgically repaired (n = 1) anal sphincter underwent permanent sacral nerve stimulation implant. Cause was traumatic in two patients, and associated disorders included scleroderma (2 patients) and spastic paraparesis (1 patient); eight (50 percent) of the patients also had urinary incontinence, and two (12.5 percent) had nonobstructive urinary retention. All patients were selected on the basis of positive findings from at least one peripheral nerve evaluation. The stimulating electrode was positioned in the S2 (1 patient), S3 (14 patients), or S4 (1 patient) sacral foramen. RESULTS: Mean follow-up was 15.5 (range, 3-45) months. Mean preimplant Williams score decreased from 4.1 +/- 0.9 (range, 2-5) to 1.25 +/- 0.5 (range, 1-2) (P = 0.01, Wilcoxon test), and the number of incontinence accidents for liquid or solid stool in 14 days decreased from 11.5 +/- 4.8 (range, 2-20) before implant to 0.6 +/- 0.9 (range, 0-2) at the last follow-up. Important manometric data were an increase in mean maximal pressure at rest of 37.7 +/- 14.9 mmHg (implantable pulse generator 49.1 +/- 18.7, P = 0.04) and in mean maximal pressure during squeeze (prestimulation 67.3 +/- 21.1 mmHg, implantable pulse generator 82.6 +/- 21.0, P = 0.09). CONCLUSIONS: Neuromodulation can be considered an option for fecal incontinence. However, an accurate clinical and instrumental evaluation and careful patient selection are required to optimize outcome.

A survey was made in 13 Italian centers with a questionnaire concerning the (a) indications, (b) postoperative complications, (c) functional results and (d) diagnostic imaging modalities related to the making of an ileal or colonic (neo) rectum. Ulcerative colitis (100%), familial polyposis (61.5%) and Crohn's disease (15.3%) were the most common indications for an ileal pouch; rectal cancer (7.96%), chronic inflammatory diseases (15.3%), diverticulosis, rectal prolapse, redundant colon and imperforate anus (7.6% each) were the most common indications for a colonic pouch. Postoperative complications included pelvic abscess (14%), sinus tract/dehiscence (10%) and bowel obstruction (9%). When compared with the S and W variants, the J-shaped ileoanal pouch proved superior because urgency and fecal retention rates were lower (18.4% vs. 44.4% and 23% vs. 28.6%, p < 0.01 and p < 0.05, respectively), despite slightly more frequent staining episodes (15.8% vs. 11.1%; p < 0.05). As for colonic ampullae, fecal retention and provoked evacuation were more frequent in the J pouch and after gracileplasty; urgency and incontinence in the straight colo-anal anastomosis (33.3% vs. 22.2% and 41.6% vs. 33.3%, respectively). The functional outcome was assessed by anal endosonography (available in 4/13 centers), defecography and anorectal manometry. Abnormal findings included: (a) reduced capacity, barium leakage, anal gaping, sphincter damage (urgency and incontinence); (b) barium retention, pouch dilatation, split evacuation, knobs and strictures (fecal retention).

The authors reviewed literature data regarding risk factors of cancer in order to produce a software that could identify asymptomatic subjects at "neoplastic risk" by means of the analysis of the relative risk (RR) of each factor of his/her life-style. More in detail, the relationship between diet and cancer, tobacco use, alcohol consumption, sexual behaviour, parity and other obstetric-gynecologic aspects, medications, occupational hazards, environmental pollution and genetic susceptibility were reviewed. A complex multi-parametric evaluation system was realized to calculate risk of cancers through computerized elaboration. The program operates on anamnestic, objective and instrumental data derived from a clinical data-base.

Postoperative thromboembolic complications do present an underestimated problem whenever their detection simply relies upon individual clinical judgement. Major abdominal operations are at increased risk of pulmonary embolism (PE) and deep vein thrombosis (DVT), mostly in advanced age, overweight subject, and in patients with cardiac or malignant diseases, or with previous venous diseases. Such patients may benefit from a peri- and postoperative prophylaxis with chemical or mechanical procedures, as a recent meta-analysis seems to suggest. In our experience, a randomized, multicentric clinical trial with defibrotide (DF) versus calcium-heparin (CH) was realized with the aim of evaluating their effectiveness and side effects in the prophylaxis of PE and DVT after major abdominal surgery; 1296 patients were randomly assigned to i.v. DF (400 mg.) or subcutaneous CH (0.2 ml. = 5000 U.I.) given one hour prior to operation and twice daily for seven days postoperatively. Definitive evaluation was carried out on 1212 patients (610 patients in DF and 602 in CH group, respectively) who completed the prophylaxis and monitoring schedule acceptably. One PE (0.16%) and 38 DVT (6.2%) were detected in DF group while 2 PE (0.33%) and 40 DVT (6.6%) were reported in CH treated patients. Post-operative blood loss was 578 +/- 150 cc. (median +/- S.E.M.) in DF group and 604 +/- 123 in CH group (p = n.s.). Wound hematoma was observed in 69 patients (5.7%): 20 (3.2%) in DF and 49 (8.1%) in CH group of patients (CHI-Square = 12.44; p = 0.0005); a significant post-operative decrease of RBC, WBC, Platelet count, and Fibrinogen was computed in both groups (p less than 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)

The present study was performed to evaluate the potential of glutaraldehyde-tanned mandril-grown grafts as caval substitutes. Short-term experiments consisted of 30 tubular grafts (35 x 8 mm), either of tanned collagen or polytetrafluoroethylene, that were sutured in the infrarenal inferior vena cava of pigs and removed 1 hour after implantation. There was no significant difference between the extent of the thrombus-lined graft surface in the biologic group and that in the polytetrafluoroethylene group. The amount of inner thrombus on tanned collagen grafts was significantly correlated to platelet activity. Long-term experiments involved 30 similar segments of both materials, which were sutured in the inferior vena cava and harvested 7, 14, 28, 56, and 112 days after operation. The 112-day patency rate of collagen grafts was 67%. The 56-day patency rate of polytetrafluoroethylene grafts was 16%. The difference was statistically significant (p less than 0.01). Collagen grafts were lined by a thin neointima (200 micron) in all but two cases. The neointima was completely endothelialized within 4 weeks from implantation. In conclusion, tanned collagen grafts may represent a suitable material for venous replacement.

A retrospective study is reported carried out on a group of 166 patients affected by dyspeptic syndrome who presented at least 3 of the 9 symptoms which characterise this pathology. One hundred and twenty-eight patients underwent prokinetic drug therapy and 38 received placebo. Clinical parameters were evaluated following one month of therapy all patients in order to compare them to basal values. The results obtained confirm a satisfactory efficacy of the prokinetic treatment in improving dyspeptic symptoms. Although administered to a smaller number of patients, placebo was also found to play an important role in the multifactorial etiopathogenesis of the dyspeptic syndrome on a functional basis.

Atropine (1 mg intravenously) and a new antimuscarinic compound, cimetropium bromide (5 mg intravenously), as well as placebo (physiological saline) were tested for their effects on gastric emptying and antroduodenal motility in healthy humans. In a first single-blind cross-over study, the emptying rate was assessed in 12 subjects by measuring paracetamol absorption. In a second single-blind parallel-group study, antroduodenal motor activity was measured in 20 subjects through four perfused open tip catheters with orifices positioned in the antroduodenal region. Atropine, unlike cimetropium bromide, significantly delayed gastric emptying. Antral and duodenal motility index was reduced significantly by atropine, but not by cimetropium bromide. Heart rate significantly increased only after atropine. Three subjects taking atropine complained of dry mouth and one of blurred vision. In conclusion, the results of these studies show that atropine, unlike cimetropium bromide, strongly inhibits gastric emptying of liquids and reduces antroduodenal motor activity in man.
