Strictureplasty leak in patients with Crohn's disease increases considerably morbidity rate. Intra-operative evaluation of the integrity of suture line and proficient management of any leakage after strictureplasty is mandatory to prevent post-operative complications. When a leakage is detected at the posterior side, through intra-operative insufflation or methylene blue test, it may be difficult to repair as the suture line is completely covered up by mesentery. The AA. describe the creation of a mesenteric window to reinforce the posterior side of a side-to-side stapled strictureplasty performed by laparoscopic assisted procedure. As far as we know, this new technical strategy may allow avoiding resection of small bowel. Strictureplasty leak in patients with Crohn's disease increases considerably morbidity rate.

Esophageal achalasia is a chronic and progressive motility disorder characterized by absence of esophageal body peristalsis associated with an impaired relaxation of lower esophageal sphincter (LES) and usually with an elevated LES pressure, leading to an altered passage of bolus through the esophago-gastric junction. A definitive cure for achalasia is currently unavailable. Palliative treatment options provide only food and liquid bolus intake and relief of symptoms. Endoscopic therapy for achalasia aims to disrupt or weaken the lower esophageal sphincter. Intra-sphincteric injection of botulinum toxin is reserved for elderly or severely ill patients. Pneumatic dilation provides superior results than botulinum toxin injection and a similar medium-term efficacy almost comparable to that attained after surgery. Per oral endoscopic myotomy is a promising option for treating achalasia, but it requires increased experience and further objective and long-term follow up. This article will review different endoscopic treatments in achalasia, and summarize the short-term and long-term outcomes.

Background: The purpose of our study was to evaluate the impact of laparoscopic adrenalectomy on patients with incidentalomas. We analyzed the results of a multi-centre trial that was performed to evaluate the effectiveness of imaging (computed tomography and magnetic resonance imaging) to obtain a correct preoperative diagnosis. Methods: We obtained our data from the results of a questionnaire that was distrib-uted by mail or email in May 2005 to several surgical units operating in the Campania Region, Italy. Lap Club, a collaborative laparoscopic surgery study group founded in Naples in 1995, distributed the questionnaire. Thirteen centres participated in the audit. In all, we analyzed 255 adrenalectomies performed on 250 patients. We per-formed statistical analysis using SPSS software. Results: The distribution of pathologic findings demonstrates that the number of lesions caused by cancer discovered from a preoperative indication of incidentaloma has been even smaller (1/114, 0.8%) than the previous numbers reported in the litera-ture. Moreover, whereas most patients with adrenal cancer had lesions larger than 6 cm (7/8, 87.5%), the majority of patients with adrenal metastases had lesions 6 cm or smaller (10/12, 83.3%). Different indications for adrenalectomy emerged on com-parison of endocrine surgery units with general surgery units. This difference appears to be significant (p < 0.001), especially on evaluation of the number of nonfunctioning adenomas and the number of endocrine lesions that were observed and treated. Conclusion: Laparoscopy remains the gold standard method for adrenalectomy, but its availability must not obligate physicians to treat with surgery when an inciden-taloma is detected through imaging. Adrenal malignancies when metastatic are often 6 cm or smaller. If they are single and they originated from a non–small lung cancer, they must be removed. The endocrine surgery unit remains the best setting to evalu-ate and treat adrenal gland surgical pathology.

Highlights • Gastric perforation caused by intragastric balloon represents a rare but life-threatening complication. • There is a lack of information about perforation in the same day of surgery. • An endoscopic and laparoscopic approach with a gastric wedge resection was performed., Introduction IGB (Intragastric Balloon) is acknowledged to be a safe and secure device, whose outcomes in terms of weight loss are widely discussed. Bariatric community has soon noted tolerance and benefit of this tool, considered a first and easy step before bariatric surgery. Nevertheless, some authors have described a series of complications that, although rare, could be life threatening and hard to manage, as a gastric perforation. Presentation of case We reported a case of a 55-year-old obese woman, undergone placement of IGB device heisting in a gastric perforation. In the same day of surgery, we performed an emergency, applying a combined endoscopic and laparoscopic approach, to remove the balloon and to close perforation by a gastric resection. Discussion. Short term outcome was satisfactory, and the patient had a successful further follow up and weight loss. Conclusion IGB is a valuable tool among bariatric procedure, nevertheless the surgeon has to consider the possible and life-threatening complications and to provide a multidisciplinary equip to face this occurrence.

Highlights • LAGB presents many severe complications. • Wedge resection could allow to preserve a tailored gastric pouch limiting postoperative nutritional defects. • Strict postoperative follow-up reduce the risk of severe complications., Introduction Laparoscopic adjustable gastric banding (LAGB) is a minimal invasive, effective and reversible procedure, even if it is burdened by life threatening complications. Presentation of the case A 39 years-old female patient was admitted to our emergency department for abdominal pain and ileus and underwent an explorative laparoscopy. The LAGB was wrapped around the proximal portion of the stomach determining the erosion and ischemia of the great curvature region. It was removed and a large gastric resection of the great curvature was performed. Subsequently, a gastric leak with pleural abscess occurred with the beginning of the oral diet. It was successfully treated with fasting, intravenous antibiotics and a thoracic tube. Discussion LAGB is a restrictive procedure that compartmentalizes the upper stomach by placing a tight adjustable band around it. However severe and multiple complications can also occur. Slippage is one of the most frequent and dangerous complication. Partial gastric resection (comparable to sleeve gastrectomy) or total/subtotal gastrectomy on the limit of the scarring tissue is use requested in the latter case, with a high risk of postoperative leak. A strict postoperative follow-up is mandatory in order to early recognize any severe complications. Conclusion Strict follow-up in this special subset of patients, the bariatric ones, is mandatory in order to early identify and correct any postoperative complications, avoiding severe sequelae.

Background To evaluate the use of a double loop reconstruction following pylorus preserving proximal pancreaticoduodenectomy (PPPPD). Methods Morbidity and mortality were evaluated in 55 patients undergoing PPPPD for malignant tumors, followed by a double loop reconstruction. Results The mean intra-operative blood loss was 908 mL ± 531. In-hospital mortality was 5.4% (3/55 pts). The mean length of hospital stay was 17 ± 5 days (range 12-45 days). Postoperative complications occurred in 25 patients (46.2%). Five patients developed an anastomotic leak, one biliary and four pancreatic (4/55; 7%). Delayed gastric emptying occurred in 8 patients (14.5%). Reoperation was required in two patients for hemorrhage. Conclusions A double loop alimentary reconstruction following PPPPD led to a low incidence of DGE and pancreatic fistula. Although mortality rate was higher than that reported by referral centres, this technique has been performed in a not specialized unit attaining acceptable results.

Background: Hiatal hernia is diagnosed by barium-swallow esophagogram or esophagogastroduodenoscopy, with possible suboptimal results. High-resolution manometry clearly identifies crural diaphragm and lower esophageal sphincter. Objectives: To assess the diagnostic accuracy of high-resolution manometry in detecting hiatal hernia compared to esophagogram and esophagogastroduodenoscopy, using as reference the surgical invivo measurement. Methods: Patients were studied with esophagogram, esophagogastroduodenoscopy, high-resolution manometry and invivo evaluation of the esophago-gastric junction. Esophago-gastric junction was classified as type I (no separation between crural diaphragm and lower esophageal sphincter); type II (≥1, ≤ 2 cm separation); type III (>2 cm). During invivo measurement, distance between the esophago-gastric junction and crural diaphragm proximal border was recorded. Results: Surgery identified 53 hiatal hernias in 100 patients. Forty-seven percent were classified as type I esophago-gastric junction, 35% type II and 18% type III. Referenced to invivo evaluation, high-resolution manometry showed superior diagnostic sensitivity and specificity (94.3% and 91.5%, respectively) to esophagogram and esophagogastroduodenoscopy, with 92.6% predictive value of a positive test and 93.5% predictive value of a negative test. The kappa value for high-resolution manometry and invivo evaluation was 0.85. High-resolution manometry showed optimal sensitivity and specificity in detecting types I, II and III esophago-gastric junction. Conclusions: High-resolution manometry enables an accurate diagnosis of hiatal hernia and a better classification than endoscopy and radiology, reaching optimal agreement with invivo assessment.

Obesity is a chronic complex disease, consequence of an unbalance between energy intake and expenditure and of the interaction between predisposing genotype and facilitating environmental factors. The aim of the study was to evaluate body composition, abdominal fat, and metabolic changes in a group of severely obese patients before and after laparoscopic gastric bypass (LGBP) at standardized (10% and 25%) total weight loss.Twenty-eight patients (14 M, 14 F; age 41.71 +/- 6.9 years; body mass index (BMI) 49.76 +/- 5.8 kg/m(2)) were treated with laparoscopic gastric bypass. All evaluations before surgery and after achieving ~10% and ~25% weight loss (WL). Body composition was assessed by bioimpedance analysis; resting metabolic rate (RMR) was measured by indirect calorimetry.Body weight, BMI, and waist circumference significantly decreased at 10% and 25% WL. We observed a significant reduction of both RMR (2,492 +/- 388 at entry vs. 2,098 +/- 346.6 at 10% WL vs. 2,035 +/- 312 kcal per 24 h at 25% WL, p = 0.001 vs. baseline) as well as of RMR corrected for fat-free mass (FFM; 35.7 +/- 6.7 vs. 34.9 +/- 9.0 at 10% WL vs. 33.5 +/- 5.4 at 25% WL kilocalorie per kilogram FFM x 24 h, p = 0.041 vs. baseline). Body composition analysis showed a relative increase in FFM and a reduction of fat mass at 25% WL. A significant reduction in blood glucose, insulin, homeostasis model assessment index was observed. Ultrasonography showed a marked decrease in the signs of hepatic steatosis.In conclusion, our study confirms that LGBP is a safe procedure in well-selected severely obese patients and has early favorable effects on both metabolic parameters and body composition. Longer-term observations are required for in-depth evaluation of body composition changes.

Introduction: The aim of the present study was to critically review the incidence of venous thromboembolism and postoperative hemorrhage in patients undergoing total thyroidectomy without preoperative prophylaxis. Methods: A prospective electronic database of all patients undergoing total thyroidectomy over a six eyear period within August 2013 in our medical unit was analyzed. The incidence of postoperative bleeding and Venous thromboembolism (VTE) was reviewed by subgrouping all patients according to a risk factor score (RFS) for VTE as outlined in the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) Best Practice Guidelines. Results: An overall 1018 consecutive patients [244 men (24%, mean age 46 ± 13 years), 778 women (76%, mean age 44 ± 17 years)] underwent total thyroidectomy. Postoperative bleeding occurred in 8/1018 patients (0.8%). One out of 1018 (0.1%) patients also subcategorized according to the RFS had VTE. The incidence of VTE complication in the entire population was lower than the risk of postoperative bleeding (P < .0001). Conclusion: The risk of developing VTE in patients who undergo total thyroidectomy for benign and malignant diseases without preoperative prophylaxis is roughly 8-fold less than developing a potentially life threatening complication as postoperative bleeding. Until large well conducted prospective studies on the impact of preoperative prophylaxis on postoperative VTE and bleeding will clarify the issue, it is conceivable to propose the use of stockings and/or anticoagulants according to the individual patient risk factors. © 2014 Published by Elsevier Ltd on behalf of Surgical Associates Ltd.

Sleeve gastrectomy (SG) is currently gaining popularity due to an excellent efficacy combined to minimal anatomic changes. However, some concerns have been raised on increased risk of postoperative gastroesophageal reflux disease (GERD) due to gastric fundus removal, section of the sling muscular fibers of gastroesophageal junction, reduced antral pump function, and gastric volume. We undertook the current study to evaluate by means of high-resolution impedance manometry (HRiM) and combined 24-h pH and multichannel intraluminal impedance (MII-pH) the impact of SG on esophageal physiology. METHODS: In this study, 25 consecutive patients had HRiM and MII-pH before and after laparoscopic SG. The following parameters were calculated at HRiM: lower esophageal sphincter (LES) pressure and relaxation, peristalsis, number of complete esophageal bolus transit, and mean total bolus transit time. The acid and non-acid GER episodes were assessed by MII-pH with the patient in both upright and recumbent positions. RESULTS: At a median follow-up of 13 months, HRiM showed an unchanged LES function, increased ineffective peristalsis, and incomplete bolus transit. MII-pH showed an increase of both acid exposure of the esophagus and number of non-acid reflux events in postprandial periods. CONCLUSIONS: Laparoscopic SG is an effective restrictive procedure that creates delayed esophageal emptying without impairing LES function. A correctly fashioned sleeve does not induce de novo GERD. Retrograde movements and increased acid exposure are probably due to stasis and postprandial regurgitation.

Introduction Obesity is a strong independent risk factor of gastroesophageal reflux disease (GERD) symptoms and esophageal erosions. However the relationship between obesity and GERD is still a subject of debate. In fact, if in most cases bariatric surgery can diminish reflux by losing a large amount of fat, on the other hand some restrictive procedure can worsen or cause the presence of GERD. Thus, it is unclear if patients candidate to bariatric surgery have to perform pre-operative reflux testing or not. Aim of the study was to verify the presence of GERD patterns in patients candidate to surgery and the need of pre-operative reflux testing. Methods All patients underwent to a standardized questionnaire for symptoms severity (GERQ), upper endoscopy, high resolution manometry (HRiM) and impedance pH-monitoring (MII-pH). Patients were stratified into: group 1 (negative for both GERQ and endoscopy), group 2 (positive for GERQ and negative for endoscopy), group 3 (positive for both GERQ and endoscopy). A healthy-volunteers group (HV) was assessed. Results One hundred thirty-nine subjects (obese, 124; HV normal weight, 15) were studied. Group 1 showed comparable mean LES pressure, peristaltic function, bolus transport and presence of hiatal hernia than HV. Group 2 showed a reduction of these parameters, while group 3 showed a statistical significant reduction in LES pressure, peristaltic function, bolus transport and increase in presence of hiatal hernia. At MII-pH, Group 1 showed a not significant increase in reflux patterns; group 2 and 3 showed a significant increase in esophageal acid exposure and in number of refluxes (both acid and weakly acid), with group 3 showing the higher grade of reflux pattern. Conclusions Obese subjects with pre-operative presence of GERD symptoms and endoscopical signs could be tested with HRM and MII-pH before undergoing bariatric surgery, especially for restrictive procedures. On the other hand, obese patients without any sign of GERD could not be tested for reflux, showing similar patterns to HV.

INTRODUCTION: Hemostasis during thyroidectomy is essential; however, the safest, most efficient and cost-effective way to achieve this is unclear. The aim of this study was to evaluate the outcome of total thyroidectomy (TT) performed with combination of harmonic scalpel (HS) and Floseal. METHODS: Patients undergone TT were divided into two groups: HS + Floseal and traditional hemostasis groups. The primary endpoint was 24-h drain output and blood-loss requiring reintervention. Secondary endpoints included surgery duration, postsurgical complications and hypocalcemia rates. RESULTS: Between September 2012 and January 2014, 165 patients were enrolled (100 to HS + Floseal, 65 to standard hemostasis); 80.5% female; mean age 42.3 years. The 24-h drain output was lower in the HS + Floseal group compared with standard TT. HS + Floseal also had a shorter mean surgery time (p < 0.0001) vs standard TT. No differences in post-surgical complications and in hypocalcemiarates between groups. CONCLUSION: combination of Floseal plus the HS is effective and safe for TT and it provides a complementary hemostatic approach.

Constipation accounts for 20% in western world population. In absence of any organic aetiology, this disorder may be related to bad alimentary habits based on inadequate introduction of the three components of stool (fibres, probiotics and water) that are essential for the physiologic activity of colon. Chronic constipation may be also associated with either colic or rectal anatomo-functional alterations. Colonic constipation (slow transit constipation) is usually related to a motility disorder (inertia coli) associated with a reduction of propagating contraction waves and decreased Cajal’ cells; on the other hand, rectal outlet dysfunction type constipation may be related to anatomical alterations (e.g. internal mucosal prolapse, rectocele) causing difficult rectal outlet and functional pelviperineal dyssynergia. The physiologic defaecatory act involves not only synchronism between rectum and anus, but even correct thoraco-abdominoperineal dynamics and vertebral position. This has to be carefully assessed by considering patient’s ability to accomplish adequate thoraco-abdominoperineal muscle movements needed for both adequate defaecatory dynamics and urine and stool retention. Therefore, the ideal treatment should not only address anatomical alterations such as mucosal prolapse, rectocele, rectorectal intussusception and sphincter defects, usually requiring a surgical approach, but even functional disorders, often insidious and difficult to detect. Surgery is mandatory to treat pathological findings, that physically represent an obstacle to fecal transit in the rectum. Many surgical techniques have been developed for the treatment of outlet obstruction with conflicting results. STARR (stapled transanal rectal resection) is a new surgical procedure that was launched by Longo in 2001. It is a minimally invasive transanal operation for rectocele and mucosal/rectal prolapse using a double circular stapler. This procedure is indicated when rectal mucosal prolapse is thought to be the cause of difficult defecation, and appears to be a rational treatment. This treatment aims to normalize the anatomical relationship of the anal mucosa with hemorrhoidal piles and anal sphincters by restoring the prolapse and improving venous perfusion. The procedure pulls the anal

We investigated early systemic sclerosis (SSc) (that is, Raynaud's phenomenon with SSc marker autoantibodies and/or typical capillaroscopic findings and no manifestations other than puffy fingers or arthritis) versus undifferentiated connective tissue disease (UCTD) to identify predictors of short-term disease evolution. Thirty-nine early SSc and 37 UCTD patients were investigated. At baseline, all patients underwent clinical evaluation, B-mode echocardiography, lung function tests and esophageal manometry to detect preclinical alterations of internal organs, and were re-assessed every year. Twenty-one early SSc and 24 UCTD patients, and 25 controls were also investigated for serum endothelial, T-cell and fibroblast activation markers. At baseline, 48.7% of early SSc and 37.8% of UCTD patients had at least one preclinical functional alteration (P > 0.05). Ninety-two percent of early SSc patients developed manifestations consistent with definite SSc (that is, skin sclerosis, digital ulcers/scars, two or more teleangectasias, clinically visible nailfold capillaries, cutaneous calcinosis, X-ray bibasilar lung fibrosis, X-ray esophageal dysmotility, ECG signs of myocardial fibrosis and laboratory signs of renal crisis) within five years versus 17.1% of UCTD patients (X 2 = 12.26; P = 0.0005). Avascular areas (HR = 4.39 95% CI 1.18 to 16.3; P = 0.02), increased levels of soluble IL-2 receptor alpha (HR = 4.39; 95% CI 1.03 to 18.6; P = 0.03), and of procollagen III aminopropeptide predicted disease evolution (HR = 4.55; 95% CI 1.18 to 17; P = 0.04). Most early SSc but only a few UCTD patients progress to definite SSc within a short-term follow-up. Measurement of circulating markers of T-cell and fibroblast activation might serve to identify early SSc patients who are more likely to develop features of definite SSc.

OBJECTIVE To assess internal organ involvement in early SSc at presentation. METHODS One hundred and fifteen patients admitted to a tertiary centre because of RP, who did not present any routinely detectable scleroderma-related internal organ involvement, were investigated for ANA and videocapillaroscopy, and underwent history and physical examination to detect symptoms/signs suggestive of SSc. Patients were then subdivided into three groups: (i) early SSc, constituted by patients without clinical manifestations other than RP, but with scleroderma marker autoantibodies and/or typical capillaroscopic abnormalities; (ii) probable SSc, constituted by patients with the same autoantibody and/or capillaroscopic status as early SSc patients, but with any of the following manifestations: digital ulcers/scars, puffy fingers, arthritis, telangiectasia, dysphagia/heartburn, shortness of breath; (iii) UCTD, constituted by patients with a specific (i.e. disease antibody marker) ANA and capillaroscopic findings plus any disease manifestation. All patients were investigated by lung functional study and B-mode echo-Doppler-cardiography. Patients who consented underwent oesophageal manometry. RESULTS An inverted mitral E : A ratio (i.e. early scleroderma cardiac involvement) and/or a diffusing lung capacity for CO

Purpose The aims of this study were to evaluate several clinical and instrumental parameters in a large number of patients with constipation and incontinence as well as in healthy controls and discuss their potential implications in the functional aspects of these disorders. Methods Eighty-four constipated and 38 incontinent patients and 45 healthy controls were submitted to a protocol based on proctologic examination, clinicophysiatric assessment, and instrumental evaluation. Results Constipated and incontinent patients had significantly worse lumbar lordosis as well as lower rate in the presence of perineal defense reflex than controls. Constipated but not incontinent patients had a lower rate of puborectalis relaxation than controls. Furthermore, worse pubococcygeal tests and a higher rate of muscle synergies presence, either agonist or antagonist, were observed in both constipated and incontinent patients compared to controls. Conclusions This study has demonstrated strong correlations between physiatric disorders and the symptoms of constipation and incontinence. Further studies designed to demonstrate a causal relationship between these parameters and the success of a specific treatment of the physiatric disorders on the proctology symptoms are warranted.

Bariatric surgery is considered the most effective treatment for reducing excess body weight and maintaining weight loss (WL) in severely obese patients. There are limited data evaluating metabolic and body composition changes after different treatments in type III obese (body mass index [BMI]40 kg/m(2)).Twenty patients (9 males, 11 females; 37.6 +/- 8 years; BMI = 50.1 +/- 8 kg/m(2)) treated with dietary therapy and lifestyle correction (group 1) have been compared with 20 matched patients (41.8 +/- 6 years; BMI = 50.4 +/- 6 kg/m(2)) treated with laparoscopic gastric bypass (LGBP; group 2). Patients have been evaluated before treatment and after10% WL obtained on average 6 weeks after LGBP and 30 weeks after integrated medical treatment. Metabolic syndrome (MS) was evaluated using the Adult Treatment Panel III/America Heart Association (ATP III/AHA) criteria. Resting metabolic rate (RMR) and respiratory quotient (RQ) was assessed with indirect calorimetry; body composition with bioimpedance analysis.At entry, RMR/fat-free mass (FFM) was 34.2 +/- 7 kcal/24 h.kg in group 1 and 35.1 +/- 8 kcal/24 h.kg in group 2 and did not decrease in both groups after 10% WL (31.8 +/- 6 vs 34.0 +/- 6). Percent FFM and fat mass (FM) was 50.7 +/- 7% and 49.3 +/- 7% in group 1 and 52.1 +/- 6% and 47.9 +/- 6% in group 2, respectively (p = n.s.). After WL, body composition significantly changed only in group 1 (% FFM increased to 55.9 +/- 6 and % FM decreased to 44.1 +/- 6; p = 0.002).After10% WL, MS prevalence decreases precociously in surgically treated patients; some improvements in body composition are observed in nonsurgically treated patients only. Further investigations are needed to evaluate long-term effects of bariatric surgery on body composition and RMR after stable WL.
