Abstract
BACKGROUND Despite the recent advances in medical therapy, the majority of patients with Crohn's disease (CD) still require surgery during the course of their life. While a correlation between early primary surgery and lower recurrence rates has been shown, the impact of surgical timing on postoperative complications is unclear. The aim of this study is to assess the impact of surgical timing on 30-day postoperative morbidity. METHODS This is a retrospective analysis of a prospectively collected database of 307 consecutive patients submitted to elective primary ileocolic resection for CD at our institution between July 1994 and July 2018. The following variables were considered: age, gender, year of treatment, smoking habits, preoperative steroid therapy, presence of fistula or abscess, type of anastomosis, and time interval between diagnosis of CD and surgery. Univariate and multivariate logistic regressions were performed to examine the association between risk factors and complications. RESULTS Major complications occurred in 29 patients, while anastomotic leak was observed in 16 patients. Multivariate logistic regression analysis showed that surgical timing in years (OR 1.10 p = 0.002 for a unit change), along with preoperative use of steroids (OR 5.45 p < 0.001) were independent risk factors for major complications. Moreover, preoperative treatment with steroids (6.59 p = 0.003) and surgical timing (OR 1.10 p = 0.023 for a unit change) were independently associated with anastomotic leak, while handsewn anastomosis (OR 2.84 p = 0.100) showed a trend. CONCLUSIONS Our results suggest that the longer is the time interval between diagnosis of CD and surgery, the greater is the risk of major surgical complications and of anastomotic leak.

Abstract
PURPOSE In patients with obesity, micronutrient deficiencies have been reported both before and after bariatric surgery (BS). Obesity is a chronic pro-inflammatory status, and inflammation increases the risk of micronutrient malnutrition. Our objective was to assess in pre-BS patients the prevalence of micronutrient deficiencies and their correlation with blood values of C-reactive protein (CRP). METHODS Anthropometric data, instrumental examinations, and blood variables were centrally measured in the first 200 patients undergoing a pre-BS evaluation at the "Città della Salute e della Scienza" Hospital of Torino, starting from January 2018. RESULTS At least one micronutrient deficiency was present in 85.5% of pre-BS patients. Vitamin D deficiency was the most prevalent (74.5%), followed by folate (33.5%), iron (32%), calcium (13%), vitamin B12 (10%), and albumin (5.5%) deficiency. CRP values were high (> 5 mg/L) in 65% of the patients. These individuals showed increased rate of iron, folate, vitamin B12 deficiency, and a higher number of micronutrient deficiencies. In a multiple logistic regression model, increased CRP levels were significantly associated with deficiencies of vitamin B12 (OR = 5.84; 95% CI 1.25-27.2; p = 0.024), folate (OR = 4.02; 1.87-8.66; p < 0.001), and with the presence of ≥ 2 micronutrient deficiencies (OR = 2.31; 1.21-4.42; p = 0.01). CONCLUSIONS Micronutrient deficiencies are common in patients with severe obesity undergoing BS, especially when inflammation is present. In the presence of increased CRP values before surgery, it might be advisable to search for possible multiple micronutrient deficiencies.

Abstract
PURPOSE Bariatric surgery (BS) has been recognized as an effective treatment for most patients with morbid obesity, but a variable range of patients failed to achieve a successful weight-loss. Controversial data are available about predictors of unsuccess. We aimed to retrospectively assess whether clinical baseline characteristics of patients submitted to sleeve gastrectomy (SL) or gastric bypass (GBP) were associated with unsuccessful weight-loss after 12 and 24-month follow-up. METHODS Three hundred patients who underwent BS from the 1st January 2016, with at least 24-months follow-up, were enrolled. Patients were divided according to their percentage of excess weight-loss (%EWL) either < 50% or ≥ 50% after 12 and 24-month follow-up. RESULTS None of the patients was lost at follow-up; 56 (18.7%) patients showed a %EWL < 50% at 24 months. Age, neck circumference, obstructive sleep apnea (OSA) were significantly higher, while total cholesterol and %EWL 6-months lower in those with %EWL < 50% at 12-months. Age, neck circumference, male and OSA rates were increased, while %EWL at 6-months lower in patients with %EWL < 50% at 24-months. In a multiple regression model, age (OR = 1.076; 95% CI 1.029-1.125; p = 0.001; OR = 1.066; 1.027-1.107; p < 0.001) and %EWL at 6-months (OR = 0.876; 0.840-0.913; p < 0.001; OR = 0.950; 0.928-0.972; p < 0.001) were associated with %EWL < 50% both at 12- and 24-months, respectively, and neck circumference (OR = 1.142; 1.011-1.289; p = 0.032) with %EWL < 50% at 24-months. CONCLUSION Older age, larger neck circumference, and %EWL at 6-months were significantly associated with BS unsuccess, showing almost 90% of those patients an unsuccessful weight-loss early after surgery. Further larger studies with longer follow-up are needed to confirm these results.

Abstract
BACKGROUND The extended lymphadenectomy (D2) was recently introduced in several guidelines as the optimal treatment for gastric cancer, based only on the 15-year follow-up results of the Dutch randomised trial, while the British Medical Research Council (MRC) study failed to demonstrate a survival benefit over the more limited D1 dissection. The Italian Gastric Cancer Study Group randomised controlled trial (RCT) was also undertaken to compare D1 versus D2 gastrectomy, and a tendency to improve survival in patients with advanced resectable disease (pT > 1N+) was documented despite negative results in the entire patient population. Now we present the 15-year follow-up results of survival and gastric cancer-related mortality. METHODS Between June 1998 and December 2006, eligible patients with gastric cancer who signed the informed consent were randomised at 5 centres to either D1 or D2 gastrectomy. Intraoperative randomisation was implemented centrally by phone call. Primary outcome was overall survival (OS); secondary end-points were disease-specific survival, postoperative morbidity and mortality. Analyses were by intention to treat. Strict quality control measures for surgery, lymph node removal, pathology and patient follow-up were implemented and monitored. Registration number: ISRCTN11154654 (http://www.controlled-trials.com). FINDINGS A total of 267 eligible patients were assigned to either D1 (133 patients) or D2 (134) procedure. Median follow-up time was 16.76 years. Analyses were done both in overall patient population and in pT > 1N+. One hundred patients (38.5) were alive without recurrence. OS and disease-specific survival (DSS) were very high in both arms. In overall population, they were not different between D1 and D2 arm (51.3% vs. 46.8% and 65% vs. 67% respectively, p = 0.31 and p = 0.94). DSS was significantly higher after D2 in pT > 1N+ patients (29.4% vs. 51.4%, p = 0.035). OS and DSS were better after D1 in patients older than 70 years (p = 0.003 and p = 0.006). DSS was higher after D1 also in early stages (p = 0.01). INTERPRETATION After 15-year follow up, despite no relevant difference in overall population, DSS and gastric cancer-related mortality of patients with advanced disease and lymph node metastases are improved by D2 procedure. Further data available from this trial suggest that D1 procedure should be preferably used in older patients and in early disease. As accurate detection of advanced diseases can be currently provided by adequate preoperative workup in referral centres, D2 procedure should be recommended in these cases.

Abstract
INTRODUCTION Transverse colon cancer (TCC) is poorly studied, and TCC cases are often excluded from large prospective randomized trials because of their complexity and their potentially high complication rate. The best surgical approach for TCC has yet to be established. The aim of this large retrospective multicenter Italian series is to investigate the advantages and disadvantages of both hemicolectomy and transverse colectomy in order to identify the best surgical approach. MATERIALS AND METHODS This was a retrospective cohort study of patients with mid-transverse colon cancer treated with a segmental colon resection or an extended hemicolectomy (right or left) between 2006 and 2016 in 28 high-volume (more than 70 procedures/year) Italian referral centers for colorectal surgery. RESULTS The study included 1529 patients, 388 of whom underwent a segmental resection while 1141 underwent an extended resection. A higher number of complications has been reported in the segmental group than in the extended group (30.1% versus 23.6%; p 0.010). In 42 cases the main complication was the anastomotic leak (4.4% versus 2.2%; p 0.020). Recovery outcomes also showed statistical differences: time to first flatus (p 0.014), time to first mobilization (p 0.040), and overall hospital stay (p < 0.001) were significantly shorter in the extended group. Even if overall survival were similar between the groups (95.1% versus 97%; p 0.384), 3-year disease-free survival worsened after segmental resection (78.1% versus 86.2%; p 0.001). CONCLUSIONS According to our results, an extended right colon resection for TCC seems to be surgically safer and more oncologically valid.

Abstract
BACKGROUND An organ-preserving strategy may be a valid alternative in the treatment of selected patients with rectal cancer after neoadjuvant radiotherapy. Preoperative assessment of the risk for tumor recurrence is a key component of surgical planning. The aim of the present study was to increase the current knowledge on the risk factors for tumor recurrence. METHODS The present study included individual participant data of published studies on rectal cancer surgery. The literature was reviewed according to according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses of Individual Participant Data checklist (PRISMA-IPD) guidelines. Series of patients, whose data were collected prospectively, having neoadjuvant radiotherapy followed by transanal local excision for rectal cancer were reviewed. Three independent series of univariate/multivariate binary logistic regression models were estimated for the risk of local, systemic and overall recurrence, respectively. RESULTS We identified 15 studies, and 7 centers provided individual data on 517 patients. The multivariate analysis showed higher local and overall recurrences for ypT3 stage (OR 4.79; 95% CI 2.25-10.16 and OR 6.43 95% CI 3.33-12.42), tumor size after radiotherapy > 10 mm (OR 5.86 95% CI 2.33-14.74 and OR 3.14 95% CI 1.68-5.87), and lack of combined chemotherapy (OR 3.68 95% CI 1.78-7.62 and OR 2.09 95% CI 1.10-3.97), while ypT3 was the only factor correlated with systemic recurrence (OR 5.93). The analysis of survival curves shows that the overall survival is associated with ypT and not with cT. CONCLUSIONS Local excision should be offered with caution after neoadjuvant chemoradiotherapy to selected patients with rectal cancers, who achieved a good response to neoadjuvant chemoradiotherapy.

Abstract
BACKGROUND Over the last decade, single-incision laparoscopic cholecystectomy (SLC) has gained popularity, although it is not evident if benefits of this procedure overcome the potential increased risk. Aim of the study is to compare the outcome of SLC with conventional multi-incision laparoscopic cholecystectomy (MLC) in a meta-analysis of randomized controlled trials only. METHODS A systematic Medline, Embase, and Cochrane Central Register of Controlled Trials literature search of articles on SLC and MLC for any indication was performed in June 2017. The main outcomes measured were overall adverse events, pain score (VAS), cosmetic results, quality of life, and incisional hernias. Linear regression was used to model the effect of each procedure on the different outcomes. RESULTS Forty-six trials were included and data from 5141 participants were analysed; 2444 underwent SLC and 2697 MLC, respectively. Mortality reported was nil in both treatment groups. Overall adverse events were higher in the SLC group (RR 1.41; p < 0.001) compared to MLC group, as well severe adverse events (RR 2.06; p < 0.001) and even mild adverse events (RR 1.23; p = 0.041). This was confirmed also when only trials including 4-port techniques (RR 1.37, p = 0.004) or 3-port techniques were considered (RR 1.89, p = 0.020). The pain score showed a standardized mean difference (SMD) of - 0.36 (p < 0.001) in favour of SLC. Cosmetic outcome by time point scored a SMD of 1.49 (p < 0.001) in favour of SLC. Incisional hernias occurred more frequently (RR 2.97, p = 0.005) in the SLC group. CONCLUSIONS Despite SLC offers a better cosmetic outcome and reduction of pain, the consistent higher rate of adverse events, both severe and mild, together with the higher rate of incisional hernias, should suggest to reconsider the application of single incision techniques when performing cholecystectomy with the existing technology.

Abstract
AIM Many different surgical techniques have been reported for the surgical treatment of full-thickness external rectal prolapse. Perianal stapled prolapse resection (PSP) is a relatively newly reported technique for full thickness external rectal prolapse. The aim of this prospective multicentre study was to evaluate the results of this procedure. METHOD Consecutive patients who underwent a PSP resection for full-thickness external rectal prolapse at five centres were recruited to the study. Median operating time, hospital stay, complications, recurrence and functional results according to the Wexner Incontinence Scale and obstructive defaecation syndrome score were recorded. RESULTS There were 27 patients treated by PSP. The median Wexner incontinence score improved from 10 presurgery to 5 after surgery (P < 0.001); the median obstructed defaecation syndrome score improved from 12 presurgery to 5 (range 4-10) after surgery (P < 0.001). A laparoscopically assisted procedure was performed in three patients (11.1%). The median number of cartridges used was six (range four to nine). The median operating time was 48 min. Early complications occurred in six patients (22.2%) and late complications in two (7.4%). The median length of hospital stay was 5 days. The recurrence rate at a median follow-up of 30.3 months was 14.8%. CONCLUSION PSP appears to be an easy, fast and safe procedure. Early functional results are good. The recurrence rate compares favourably with other perineal procedures like the Delorme or the Altemeier operations. Long-term functional results need to be investigated further.

Abstract
AIM Transanal endoscopic microsurgery (TEM) was originally invented by Buess et al. (Chirurg, 1984, 55, 677-80) for the treatment of infraperitoneal rectal adenomas. Its indications have progressively expanded to include larger and more advanced lesions. The aim of the study was to report the results of TEM used for the treatment of circumferential rectal lesions. METHOD We retrospectively reviewed the medical records of 17 consecutive patients [median age 69 (32-89) years; nine men] who underwent TEM for a circumferential rectal lesion in our department between September 2010 and January 2015. RESULTS The median distance from the anal verge was 4 (3-11) cm, the median longitudinal extent was 7 (3-10) cm and the median surface area was 75 (40-255) cm(2) . An end-to-end anastomosis without proximal bowel mobilization was completed endoscopically in all cases. The median operating time was 120 (40-240) min. Persistent, endoscopically uncontrollable endoluminal bleeding in one patient was successfully treated with a second TEM procedure. One patient underwent preoperative radiotherapy for adenocarcinoma detected at the preoperative assessment. Surgical histology showed a pT3 cancer in one patient who refused further surgery, a pT2 cancer in two who subsequently underwent abdominoperineal resection, a pT1 cancer in four and a ypT0 in one patient. All are at present free of disease. No patients developed faecal incontinence or urinary or sexual dysfunction. Four patients required endoscopic balloon dilatation for stenosis. CONCLUSION Transanal endoscopic microsurgery is a feasible and safe technique for large circumferential lesions with a satisfactory outcome. Preoperative staging may be inaccurate.

Abstract
Digestive diseases are a major burden for society and healthcare systems, and with an aging population, the importance of their effective management will become critical. Healthcare systems worldwide already struggle to insure quality and affordability of healthcare delivery and this will be a significant challenge in the midterm future. Wireless capsule endoscopy (WCE), introduced in 2000 by Given Imaging Ltd., is an example of disruptive technology and represents an attractive alternative to traditional diagnostic techniques. WCE overcomes conventional endoscopy enabling inspection of the digestive system without discomfort or the need for sedation. Thus, it has the advantage of encouraging patients to undergo gastrointestinal (GI) tract examinations and of facilitating mass screening programmes. With the integration of further capabilities based on microrobotics, e.g. active locomotion and embedded therapeutic modules, WCE could become the key-technology for GI diagnosis and treatment. This review presents a research update on WCE and describes the state-of-the-art of current endoscopic devices with a focus on research-oriented robotic capsule endoscopes enabled by microsystem technologies. The article also presents a visionary perspective on WCE potential for screening, diagnostic and therapeutic endoscopic procedures.

Abstract
PURPOSE This study aimed at investigating whether the irradiated volume of pelvic bone marrow (PBM) and specific subsites may predict the occurrence of acute hematologic toxicity (HT) in anal cancer patients undergoing concurrent chemo-radiation. METHODS 50 patients, submitted to IMRT and concurrent chemotherapy, were analyzed. Several bony structures were defined on planning-CT: PBM and lumbar-sacral (LSBM), lower pelvis (LPBM) and iliac (IBM) bone marrow. On dose-volume histograms, dosimetric parameters were taken. Endpoints included white blood-cell-count (WBC), absolute-neutrophil-count (ANC), hemoglobin (Hb) and platelet nadirs and acute hematologic toxicity (HT) according to RTOG scoring scale. Generalized linear modeling was used to find correlations between dosimetric variables and blood cell nadirs, while logistic regression analysis was used to test correlation with ≥G3 HT. Receiver Operating Characteristic (ROC) curve analysis was used to evaluate the optimal cut-off points for predictive dosimetric variables with the Youden method. RESULTS Maximum detected acute HT comprised 38 % of ≥G3 leukopenia and 32 % of ≥G3 neutropenia. Grade 2 anemia was observed in 4 % of patients and ≥G3 thrombocytopenia in 10 %. On multivariate analysis a higher PBM-V 20 was associated with lower WBC nadir. Increased LSBM-V 40 was correlated with a higher likelihood to develop ≥G3 HT. A cut-off point at 41 % for LSBM-V 40 was found. Patients with LSBM-V 40 ≥41 % were more likely to develop ≥G3 HT (55.3 vs. 32.4 %; p < 0.01). CONCLUSIONS Increased low-dose to pelvic bony structures significantly predicted for WBC decrease. Medium-high dose to specific osseous subsites was associated with a higher probability of HT. LSBM-V 40 was a strong predictor of ≥G3 HT. A threshold at 41 % for LSBM-V 40 could be used to limit HT.

Abstract
Abstract
Background
Transanal Endoscopic Operation (TEO®) for rectal benign lesions and early rectal cancer may provide better oncological outcomes than flexible endoscopy. The major advantage of flexible endoscopy is that it does not require general anaesthesia. This prospective observational study assessed the feasibility and safety of TEO® performed under spinal anaesthesia.
Methods
The study population comprised eligible consecutive patients who underwent TEO® under spinal anaesthesia with curative or palliative intent for rectal neoplasms larger than 20 mm in diameter or for recurrent lesions of any size. The primary endpoints were feasibility and safety; secondary endpoints were postoperative pain, as measured on a visual analogue scale, heart rate, systolic and diastolic BP, opioid requested, postoperative nausea or vomiting, and urinary retention.
Results
The study included 50 patients (median age 70 years; 29 men and 21 women). No intraoperative complications occurred. The median duration of operation was 60 (range 20–165) min. No opioids were requested during the perioperative or postoperative period. The median postoperative pain score was 0 at 4, 8, 24 and 48 h after surgery. There were no significant fluctuations in heart rate, systolic and diastolic BP up to 48 h after the procedure (P = 0·379, P = 0·386 and P = 0·617 respectively). Postoperative nausea and vomiting occurred in one patient, and urinary retention in four.
Conclusion
TEO® under spinal anaesthesia was safe and feasible with no conversions to general anaesthesia.

Abstract
AIM Single-incision laparoscopic surgery (SILS) has been proposed as the next step in minimally invasive surgery for appendicectomy. Previous reviews have summarized the results of low-evidence comparative studies, suggesting that the two approaches are comparable in terms of outcomes but showing the need for randomized controlled trials (RCTs). This review offers a meta-analyses of RCTs on this topic to evaluate the safety and efficacy of single-incision laparoscopic appendectomy (SILA). METHOD A comprehensive research of electronic databases was performed. Primary outcomes (overall and access-specific morbidity) were designated as safety issues. Secondary outcomes were pain, cosmesis, operative time, conversion rate and length of hospital stay. RESULTS After exclusions, five RCTs satisfied the inclusion criteria. They included a total of 761 patients [379 SILA and 382 conventional three-port laparoscopic appendectomies (CLA)]. No significant differences were found in overall morbidity, early wound morbidity or length of stay between SILA and CLA. Cosmesis and pain were not comparable due to different scales and time records. Conclusions on the incisional hernia rate were not reliable due to short follow-up periods. CONCLUSION SILA can be considered an acceptable alternative to CLA in the treatment of acute appendicitis, but an economic evaluation of the various techniques for single access must be performed before its widespread clinical introduction. Better-designed RCTs are necessary to define a population in which SILA could have major benefits.

Abstract
Lymphogranuloma venereum (LGV) is a sexually transmitted infection endemic in parts of Africa, Asia, South America, and the Caribbean, but once was rarely observed in Western countries, where most cases were considered to be imported. However, recent outbreaks have been reported in Europe, Australia, New Zealand, the United States and Canada, mainly among HIV positive men who have sex with men, signaling LGV re-emergence. The etiological agent of LGV is Chlamydia trachomatis serotypes L1, L2 and L3, and current outbreaks are mostly sustained by L2b type. The clinical course can be classically divided into three stages: an initial papule, which may ulcerate at the site of inoculation, followed by regional lymphoadenopathy (second stage, generally unilateral). In the tertiary stage, lymphatic obstruction, with elephantiasis of genitalia, and rectal involvement can lead to the formation of strictures and fistulae that may require surgical treatment. Recent cases are observed mainly among HIV positive people, often co-infected with HCV and others STIs, engaging in high-risk sexual practices. The main clinical picture is a relative new entity characterized by progressive ulcerative proctitis, the so called anorectal syndrome. Diagnosis is often delayed, requires a high index of clinical suspicion and must rely on the use of nucleic acid amplification tests. The differential diagnosis of proctitis should include LGV infection. Gastroenterologists, coloproctologists, dermatologists and other specialists need to be aware of LGV proctitis to avoid diagnostic delay and progression of disease to the tertiary stage.

Abstract
BACKGROUND It is still unclear whether D2 lymphadenectomy improves the survival of patients with gastric cancer and should therefore be performed routinely or selectively. The aim of this multicentre randomized trial was to compare D2 and D1 lymphadenectomy in the treatment of gastric cancer. METHODS Between June 1998 and December 2006, patients with gastric adenocarcinoma were assigned randomly to either D1 or D2 gastrectomy. Intraoperative randomization was implemented centrally by telephone. Primary outcome was overall survival; secondary endpoints were disease-specific survival, morbidity and postoperative mortality. RESULTS A total of 267 eligible patients were allocated to either D1 (133 patients) or D2 (134) resection. Morbidity (12.0 versus 17.9 per cent respectively; P = 0.183) and operative mortality (3.0 versus 2.2 per cent; P = 0.725) rates did not differ significantly between the groups. Median follow-up was 8.8 (range 4.5-13.1) years for surviving patients and 2.4 (0.2-11.9) years for those who died, and was not different in the two treatment arms. There was no difference in the overall 5-year survival rate (66.5 versus 64.2 per cent for D1 and D2 lymphadenectomy respectively; P = 0.695). Subgroup analyses showed a 5-year disease-specific survival benefit for patients with pathological tumour (pT) 1 disease in the D1 group (98 per cent versus 83 per cent for the D2 group; P = 0.015), and for patients with pT2-4 status and positive lymph nodes in the D2 group (59 per cent versus 38 per cent for the D1 group; P = 0.055). CONCLUSION No difference was found in overall 5-year survival between D1 and D2 resection. Subgroup analyses suggest that D2 lymphadenectomy may be a better choice in patients with advanced disease and lymph node metastases.

Abstract
AIM Routine prophylactic inguinal irradiation in anal cancer may cause significant toxicity associated with overtreatment bias. The aim of this study was to determine the risk of regional node metastases in anal carcinoma by identifying predictive molecular biomarkers. METHOD Clinicohistopathological data from 50 pretreatment anal carcinoma biopsies were collected. Immunohistochemical analyses with antibodies against Ki67, p53, epidermal growth factor receptor (EGFR) and YKL-40 were performed. Statistical correlations between biomarkers and clinicopathological features and outcomes were studied. Sentinel lymph node biopsy was performed in a subset of 36 patients. RESULTS All patients had undergone synchronous radiochemotherapy; tumour recurrence had developed in 26%, and 16% had died. YKL-40 tumour expression correlated with lymph node metastasis, whereas no inguinal node metastases were found in any of the (14%) patients presenting with a YKL-40/EGFR-negative tumour. YKL-40 expression and node metastasis were both significantly associated with shorter overall and disease-free survival. Tumour grade significantly correlated with disease-free survival only. HIV, tumour histological type, Ki67, p53 and EGFR were not associated with outcome. CONCLUSION YKL-40 expression in anal carcinoma is correlated with a poor outcome and can predict lymph node metastases. The combined absence of YKL-40 and EGFR expression in a first biopsy of anal carcinoma reliably selects a subset of patients without inguinal metastases. Such patients could be spared sentinel lymph node biopsy and/or inguinal radiotherapy.

Abstract
Background: Inguinal metastases in patients affected by anal cancer are an independent prognostic factor for local failure and overall mortality. Since 2001, sentinel lymph node biopsy was applied in these patients. This original study reports an update of personal and previous published series, which were compared with Literature to value the incidence of inguinal metastases T-stage related and the overall incidence of false negative inguinal metastases at sentinel node. Methods: In all, 63 patients diagnosed with anal cancer submitted to inguinal sentinel node. Furthermore a research in the Pub Med database was performed to find papers regarding this technique. Results: In our series, detection rate was 98.4%. Inguinal metastases were evidentiated in 13 patients (20.6%). Our median follow-up was 35 months. In our series, no false negative nodes were observed. Conclusion: Sentinel node technique in the detection of inguinal metastases in patients affected by anal cancer should be considered as a standard of care. It is indicated for all T stages in order to select patients to be submitted to inguinal radiotherapy, avoiding related morbidity in negative ones. An overall 3.7% rate of false negative must be considered acceptable.

Abstract
BACKGROUND Despite being considered the most effective method for colorectal cancer diagnosis, colonoscopy take-up as a mass-screening procedure is limited mainly due to invasiveness, patient discomfort, fear of pain, and the need for sedation. In an effort to mitigate some of the disadvantages associated with colonoscopy, this work provides a preliminary assessment of a novel endoscopic device consisting in a softly tethered capsule for painless colonoscopy under robotic magnetic steering. METHODS The proposed platform consists of the endoscopic device, a robotic unit, and a control box. In contrast to the traditional insertion method (i.e., pushing from behind), a "front-wheel" propulsion approach is proposed. A compliant tether connecting the device to an external box is used to provide insufflation, passing a flexible operative tool, enabling lens cleaning, and operating the vision module. To assess the diagnostic and treatment ability of the platform, 12 users were asked to find and remove artificially implanted beads as polyp surrogates in an ex vivo model. In vivo testing consisted of a qualitative study of the platform in pigs, focusing on active locomotion, diagnostic and therapeutic capabilities, safety, and usability. RESULTS The mean percentage of beads identified by each user during ex vivo trials was 85 ± 11%. All the identified beads were removed successfully using the polypectomy loop. The mean completion time for accomplishing the entire procedure was 678 ± 179 s. No immediate mucosal damage, acute complications such as perforation, or delayed adverse consequences were observed following application of the proposed method in vivo. CONCLUSIONS Use of the proposed platform in ex vivo and preliminary animal studies indicates that it is safe and operates effectively in a manner similar to a standard colonoscope. These studies served to demonstrate the platform's added advantages of reduced size, front-wheel drive strategy, and robotic control over locomotion and orientation.

Abstract
Surgical techniques and technologies are rapidly evolving. In the field of colorectal surgery the transanal video-assisted approach was introduced by Buess, 30 years ago, with transanal endoscopic microsurgery (TEM). In more recent years different techniques and technologies have been proposed, including natural orifice specimen extraction (NOSE), natural orifice transluminal endoscopic surgery (NOTES) and single-access surgery. Furthermore, a better understanding of the prognostic and risk factors of rectal cancer has allowed TEM to expand its indications to local resection of selected tumours, and more recently there have been proposals for sentinel node biopsy in colon and rectal cancer.

Abstract
BACKGROUND Of the few studies that have investigated quality-of-life (QoL) outcomes after transanal endoscopic microsurgery (TEM), the majority have reported only short-term follow-up data. This study assessed long-term clinical and instrumental outcomes (QoL, sexual, urinary and sphincter function) after TEM for extraperitoneal rectal cancer. METHODS Preoperative and postoperative anorectal function was assessed in consecutive patients with benign rectal lesions or early rectal cancer, based on clinical scores and anorectal manometry. RESULTS Between January 2000 and July 2005, 93 patients undergoing TEM completed the 60-month study protocol. The mean Wexner continence score increased from baseline at 3 months, began to decline within 12 months, and had returned to the preoperative value at 60 months. Urgency was reported by 65·0, 30·0 and 5 per cent of patients at 3, 12 and 60 months respectively (P < 0·050). A significant improvement was noted in various clinical and QoL scores at 12 and 60 months. Postoperative manometry values at 3 months were significantly lower than at baseline (P < 0·050), but had returned to preoperative values at 12 months. Tumour size of 4 cm or above was the only factor that significantly (P = 0·008) affected the rectal sensitivity threshold, the urge to defaecate threshold and the maximum tolerated volume at 3 months after TEM. CONCLUSION TEM had no long-term effect on anorectal function or QoL. Lower anal resting pressure at early follow-up was not associated with defaecation problems in patients who were continent before surgery.

Abstract
AIM Can the tension-free suturless technique, used in the surgical treatment of inguinal hernia, to be the gold standard for treatment of inguinal hernia? METHODS The tension-free suturless technique is often criticized as a fundamental principle: do not have suture. The criticism stems from concern that the mesh can migrate and cause damage to important anatomical structures. We conducted a study on the mobility of prosthesis on 33 patients, by using titanium clips that we have fixed on the meshes corner, X-rays over time, done at last, a follow-up of ten years. RESULTS The study shows that the prosthesis moves together with the anatomical space in which there is the forces present in the inguinal canal: gravity, intra-abdominal pressure, reactive force ascending gait. Across thirty-three patients have relapsed in the first six months and two recurrences in ten years, in the reconstitution of the neo-orifice, through which passes the cord. In the remaining patients the mesh were relocated upward and medially (as identified by the clips of the increase of 10-15%). CONCLUSION Our study shows that the mesh migrates upwards and medially. Migration is more or less, depending on the patient's age and quality of its tissue. Fix the prosthesis is good practice to secure at the flag on the inguinal ligament leads to two advantages: not to frustrate the principle tension-free, since the fixed prosthesis on one side does not create moments of tension, and prevent the prosthesis returns to the opening road to relapse.

Abstract
The pancreatitis-associated protein (PAP) family (also known as the regenerating gene (Reg) family) is a group of 16 kDa secretory proteins structurally classified as the calcium dependent-type lectin superfamily. Some PAP family members are expressed in neurons following peripheral nerve injury and traumatic brain injury. To determine whether PAP family members are expressed in non-traumatic brain injury, expressions were analyzed following kainic acid (KA)-induced seizure. PAP-I (also known as Reg2 in rat and RegIII-beta in mouse) and pancreatitis associated protein-III (PAP-III; RegIII-gamma in mouse) messenger ribonucleic acid (mRNA) was transiently expressed in some restricted areas, such as the hippocampus and parahippocampal area; expression was observed immediately at a maximal level 1 day after seizure. Expression disappeared within 3 days after seizure. In situ hybridization (ISH) and immunohistochemistry revealed neuronal PAP-I and PAP-III expression in the hippocampal dentate gyrus, perirhinal and entorhinal cortices, and the posterior cortical nucleus of the amygdala. The number of PAP-III mRNA-positive neurons was significantly greater than PAP-I mRNA-positive neurons. The majority of positive neurons co-localized with c-Jun, but not with glutamic acid decarboxylase (GAD). These results may suggest that PAP-I and PAP-III induction in non-GABAergic neurons would protect neurons against damage following seizure.

Abstract
Enterovesical fistula (EVF) is an abnormal communication between the intestine and the bladder. It represents a rare complication of inflammatory or neoplastic disease, and traumatic or iatrogenic injuries. The most common aetiologies are diverticular disease and colorectal carcinoma. Over 75% of affected patients describe pathognomonic features of pneumaturia, faecaluria and recurrent urinary tract infections. The diagnosis of EVF can be challenging, and frequently patients are monitored for months before the condition is recognised and treated effectively. Diagnostic tools include laboratory tests, imaging studies and endoscopic procedures. Although conservative management can be attempted in selected patients, in most cases, the treatment is mainly based on surgical interventions. Recently, the laparoscopic approach to EVF has been shown to be safe and effective. Although it is a rare condition in a general surgery setting, EVF is a challenging condition leading to high morbidity and mortality rates.

Abstract
BACKGROUND AND STUDY AIMS The use of magnetic fields to control operative devices has been recently described in endoluminal and transluminal surgical applications. The exponential decrease of magnetic field strength with distance has major implications for precision of the remote control. We aimed to assess the feasibility and functionality of a novel wireless miniaturized mechanism, based on magnetic forces, for precise orientation of the camera. MATERIALS AND METHODS A remotely controllable endoscopic capsule was developed as proof of concept. Two intracapsular moveable permanent magnets allow fine positioning, and an externally applied magnetic field permits gross movement and stabilization. Performance was assessed in ex vivo and in vivo bench tests, using porcine upper and lower gastrointestinal tracts. RESULTS Fine control of capsule navigation and rotation was achieved in all tests with an external magnet held steadily about 15 cm from the capsule. The camera could be rotated in steps of 1.8 degrees . This was confirmed by ex vivo tests; the mechanism could adjust the capsule view at 40 different locations in a gastrointestinal tract phantom model. Full 360 degrees viewing was possible in the gastric cavity, while the maximal steering in the colon was 45 degrees in total. In vivo, a similar performance was verified, where the mechanism was successfully operated every 5 cm for 40 cm in the colon, visually sweeping from side to side of the lumen; 360 degrees views were obtained in the gastric fundus and body, while antrally the luminal walls prevented full rotation. CONCLUSIONS We report the feasibility and effectiveness of the combined use of external static magnetic fields and internal actuation to move small permanent intracapsular magnets to achieve wirelessly controllable and precise camera steering. The concept is applicable to capsule endoscopy as to other instrumentation for laparoscopic, endoluminal, or transluminal procedures.

Abstract
BACKGROUND AND STUDY AIMS Capsular endoscopy holds promise for the improved inspection of the gastrointestinal tract. However, this technique is limited by a lack of controlled capsule locomotion. Magnetic steering has been proposed by the main worldwide suppliers of commercial capsular endoscopes and by several research groups. The present study evaluates and discusses how robotics may improve diagnostic outcomes compared with manual magnetic steering of an endoscopic capsule. MATERIALS AND METHODS An endoscopic capsule prototype incorporating permanent magnets was deployed in an ex vivo colon segment. An operator controlled the external driving magnet manually or with robotic assistance. The capsule was maneuvered through the colon, visualizing and contacting targets installed on the colon wall. Procedure completion time and number of targets reached were collected for each trial to quantitatively compare manual versus robotic magnetic steering ( T-test analysis with P = 0.01). Then, through a set of in vivo animal trials, the efficacy of both approaches was qualitatively assessed. RESULTS In ex vivo conditions, robotic-assisted control was superior to manual control in terms of targets reached (87 % +/- 13 % vs 37 % +/- 14 %). Manual steering demonstrated faster trial completion time (201 +/- 24 seconds vs 423 +/- 48 seconds). Under in vivo conditions, the robotic approach confirmed higher precision of movement and better reliability compared with manual control. CONCLUSIONS Robotic control for magnetic steering of a capsular endoscope was demonstrated to be more precise and reliable than manual operation. Validation of the proposed robotic system paves the way for automation of capsular endoscopy and advanced endoscopic techniques.

Abstract
BACKGROUND AND STUDY AIMS Natural orifice transluminal endoscopic surgery holds promise for surgical interventions. Before the feasibility of this technique can be established, however, secure sealing of the transluminal access needs to be thoroughly investigated. PATIENTS AND METHODS Following antibiotic prophylaxis and gastric disinfection, nine pigs underwent transgastric cholecystectomy by means of a flexible endoscope with the aid of a transabdominal 5-mm trocar. The gastric wall was punctured and dilated. The gallbladder was retracted with a laparoscopic grasper. The cystic duct and artery were dissected with a flexible monopolar ball electrode. The cystic duct was interrupted with flexible scissors between endoclips. Cholecystectomy was completed and the gallbladder was retrieved through the stomach. The gastric defect was closed using a single modified over-the-scope clip (OTSC) (Ovesco, Tübingen, Germany) and grasping the serosal and muscle layer of the gastric wall. The animals were sacrificed 4 weeks later. RESULTS Laparoscopic-assisted transgastric cholecystectomy was successful in all cases without significant perioperative complications. All animals survived without postoperative complications. The mean operating time was 128 minutes (range, 85 - 205 minutes). The gastric defect closure resulted in inversion of the gastric wall layers within an average time of 6.8 +/- 5 minutes. At 4 weeks postoperative, only minimal thin adhesions were observed in the right hypochondrium. CONCLUSIONS We found gastric closure using the OTSC to be a reliable tool for closing the transgastric access. Laparoscopic-assisted transgastric cholecystectomy by means of a flexible endoscope was technically feasible, but remains a demanding procedure.

Abstract
BACKGROUND The newly designed over-the-scope clip (OTSC) seems to overcome several limitations of current clipping system, such as size and opening-closing force, allowing better control of gastric or colonic bleeding and/or deep wall defect or perforation. AIMS The aim of this retrospective analysis was to describe the new endoscopic device and evaluate our first clinical experience. PATIENTS AND METHODS We treated with the OTSC system 9 patients (range, 58-85 years; 6 men, 3 women) with bleeding and/or deep wall lesions of the GI tract. The OTSC system is composed of an application cap, which is mounted onto the distal tip of the endoscope and a connected releasing mechanism, installed on the handle of the scope. The rotation of the handle allows the release of the clip by a two tube sliding mechanism. RESULTS All applications resulted successful, i.e. haemostasis was achieved, and/or wall defects could be closed. No complication was observed that could be ascribed to the clip itself or to the technique. CONCLUSIONS The OTSC system is a new endoscopic tool for compression of large tissue areas and its indications are nonvaricose bleedings difficult to control and lesions or perforations of the GI tract. The initial clinical use of this clipping device proved to be efficient and effective.

Abstract
We investigate a domain structure of pseudospins, a soliton lattice in the bilayer quantum Hall state at total Landau level filling factor nu = 1, in a tilted magnetic field, where the pseudospin represents the layer degree of freedom. An anomalous peak in the magnetoresistance Rxx appears at the transition point between the commensurate and incommensurate phases. The Rxx at the peak is highly anisotropic for the angle between the in-plain magnetic field B parallel and the current, and indicates a formation of the soliton lattice aligned parallel to B parallel. The temperature dependence of the Rxx peak reveals that the dissipation is caused by thermal fluctuations of pseudospin solitons. We also study a phase diagram of the bilayer nu = 1 system, and the effects of density imbalance between the two layers.

Abstract
AIM The advent of laparoscopic surgery produced a new interest in the surgical treatment of many benign and functional gastrointestinal diseases; one of the most commonly treated is the gastroesophageal reflux disease (GERD). In this paper the Authors report their 15 years experience in the laparoscopic surgical management of GERD. METHODS From October 1991 to June 2005, 581 patients with GERD were treated by a laparoscopic fundoplication with a 360 degrees wrap (524 cases) or with a 270 degrees wrap (29 cases) or with a Collis gastroplasty (28 cases). RESULTS The absence of intraoperative mortality, a low conversion to open surgery (0.7%) and a low postoperative morbidity (2.4%) with good clinical and instrumental long term results let the Authors to think that GERD represent an ideal indication for laparoscopic surgery. CONCLUSIONS Good results are possible in the laparoscopic management of GERD with a precise selection of patients and with a good open and laparoscopic surgical experience in the management of functional esophageal diseases.
