Background: A worrying increase of gastroesophageal reflux disease (GERD) and Barrett esophagus has been reported after sleeve gastrectomy (SG). Recent reports on combined fundoplication and SG seem to accomplish initial favorable results. However, no study included manometry or pH monitoring to evaluate the impact of fundoplication in SG on esophageal physiology. Method: In this study, 32 consecutive bariatric patients with GERD and/or esophagitis had high-resolution impedance manometry (HRiM) and combined 24-h pH and multichannel intraluminal impedance (MII-pH) before and after laparoscopic sleeve gastrectomy associated to anterior fundoplication (D-SLEEVE). The following parameters were calculated at HRiM: lower esophageal sphincter pressure and relaxation, peristalsis, and mean total bolus transit time. The acid and non-acid GER episodes were assessed by MII-pH, symptom index association (SI), and symptom-association probability (SAP) were also analyzed. Results: At a median follow-up of 14months, HRiM showed an increased LES function, and MII-pH showed an excellent control of both acid exposure of the esophagus and number of reflux events. Bariatric outcomes (BMI and EWL%) were also comparable to regular SG (p = NS). Conclusion: D-SLEEVE is an effective restrictive procedure, which recreates a functional LES pressure able to control and/or prevent mild GERD at 1-year follow-up.

Background: Obesity represents a critical health issue and it is also a risk factor for pelvic floor disorders (PFD). It is important to screen patients for obesity to assess their quality of life (QOL) and reduce health care costs. Methods: We evaluated the prevalence of PFD, such as urinary incontinence (UI), fecal incontinence (FI), constipation, rectal and female pelvic organ prolapse, and also the QOL of obese patients referred to our center. Results: The most prevalent PFD was constipation, affecting 18% (n = 71) of the patients, 11% for FI (n = 43), and 17% for UI (n = 67). The QOL, according to the Short Form-36 results, was worse in the obese group with PFD than the obese patients without PFD (p < 0.01). In only one subscale, mental health, the difference was not statistically different. Conclusions: The prevalence of PFD was almost similar between the obese and the control group. However, obese patients with PFD present a lower QOL than obese patients without PFD. This aspect is essential to investigate on embarrassing health problems, often hidden by patients, to improve QOL.

Background. We aim to evaluate morphofunctional changes of the sphincter complex after GateKeeper (GK) and SphinKeeper (SK) procedures and correlate these with symptom improvement. Methods. Ten consecutive females undergoing SK implant were age-matched with a cohort of 10 females who previously underwent the GK procedure. Patients in the SK and GK groups underwent implantation of 10 and 6 prostheses, respectively. Muscle tension ( Tm), expressed in millinewtons per centimetre squared, mN (cm2)−1, was calculated using the equation Tm = P( r i)( tm)−1, where P is the average maximum squeeze pressure and r i and tm the inner radius and thickness of the external anal sphincter, respectively. The pre- and postimplant changes in Tm and Cleveland Clinic Fecal Incontinence Score (CCFIS) were tested by linear and Poisson regression models, respectively. Results. The CCFIS significantly improved in both groups at 12-month postimplantation. Although not reaching statistical significance, symptom improvement after SK was 33% above that observed after GK ( P = .088). Compared to the baseline, a significant increase in Tm was observed in both groups at 12 months (GK, 508.1 [478.8-568.0] vs 864.4 [827.0-885.8] mN (cm2)−1; SK, 528.0 [472.7-564.0] vs 858.6 [828.0-919.6] mN (cm2)−1, P = .005). Compared to the GK group, Tm was significantly higher in patients after SK implant (158.3 mN (cm2)−1 [95% confidence interval, 109.6-207.0]; P < .001), after controlling for baseline values, at 12-month postimplantation. Conclusions. GK and SK are safe and effective treatments for FI with good short-term clinical outcomes. Comparative analysis showed superiority of SK over GK in terms of gain in Tm, with borderline significantly better improvement in symptoms. Larger studies are needed to confirm these findings.

Stapler-less laparoscopic sleeve gastrectomy (LSG) is emerging as a new potential affordable cost-effective alternative procedure. However, no pre-clinical data are currently available on human tissue. We aimed to evaluate whether traditionally suturing without the use of surgical stapling may produce a comparable bursting pressure on human gastric tissue. A prospective cohort of consecutive patients undergoing LSG was divided in two groups to compare a barbed extra-mucosal running suture (stapler-less) versus a standard stapler line. A burst pressure test was applied to the gastric specimen employing high-resolution manometric catheter. Type, location and features of the leak were described. We enrolled a total of 40 obese patients, 20 patients for each group. Median burst pressures of the stapler-less group resulted statistically significant increased (p p = N.S.), more often at the proximal stomach (p

Sacrococcigeal pilonidalis disease (SPD) recurrence is a major factor influencing surgical outcomes. Several different surgical treatments have been reported, however, there is a lack of long-term data on reoperation. Aim of this study was to analyze outcomes of a single center adopting a standardized off-midline asymmetric procedure (D-shape). Analytic longitudinal assessment of 83 patients (median age 35years, range 23–59years) with recurrent SPD that completed the 5-year study design following D-shape reoperation. Among a cohort of 607 patients, we enrolled 83 recurrent SPD. After D-shape reoperation, second recurrence rate was 9.6% (8/83). Second recurrence rate was not statistically significantly different among patients undergone D-shape as first surgery compared to patients of symmetric excision group (11.8% vs. 7.4%, p = 0.57). Similarly, there was no statistical difference among patients who underwent D-shape as first surgery compared to patients who underwent symmetric excision elsewhere (11.8% vs. 9.1%, p =.75). D-shape is a safe and effective when adopted as revisional surgery at a long-term follow-up. Comparative evaluation is warranted to establish the potential superiority over different surgical surgery in case of recurrence.

After the initial widespread diffusion, laparoscopic adjustable gastric banding (LAGB) has been progressively abandoned and laparoscopic sleeve gastrectomy (LSG) has become the worldwide most adopted procedure. Nevertheless, recent reports raised concerns about the long-term weight regain after different bariatric techniques. Considering the large LAGB series recorded in our multicentric bariatric database, we analysed the anthropometric and surgical outcomes of obese patients underwent LAGB at a long-term follow-up, focusing on LAGB management. Between January 2008 to January 2018, demographics, anthropometric and post-operative data of obese patients undergone LAGB were retrospectively evaluated. To compare the postoperative outcomes, the cohort was divided in two groups according to the quantity of band filling (QBF): low band filling group (Group 1) with at most 3 ml of QBF, and patients in the high band filling group (Group 2) with at least 4 ml. 699 obese patients were considered in the analysis (351 in Group 1 and 348 in Group 2). Patients in Group 1 resulted significantly associated (p p

Purpose: Hemorrhoidal disease (HD) is a widespread condition severely influencing patients' quality of life. Recently, the large diffusion of stapled hemorrhoidopexy has revealed a new unexpected pathological entity: the asymmetric mucosal prolapse. We aimed to assess the outcomes of the sectorial longitudinal augmented prolapsectomy (SLAP), a technique dedicated to asymmetric prolapse, in terms of HD symptoms, prolapse recurrence, and rectal stenosis. Methods: Patients affected by III-IV-degree symptomatic HD with asymmetric mucosal prolapse undergone SLAP of 1 or 2 hemorrhoidal columns (SLAP1 or SLAP2) were retrospectively assessed. The severity of hemorrhoid symptoms and fecal continence status were evaluated before and after surgery. Mean outcome was evaluation of medium-long-term outcomes as the occurrence of recurrence and anal or rectal stenosis. Secondary outcome was the evaluation of postoperative bleeding, reoperation rate, length of hospitalization, fecal urgency, and time to return to work. Results: We enrolled 433 patients (277 SLAP1 and 156 SLAP2). Hemorrhoidal symptoms recurrence was reported in 9 patients undergone SLAP1 and 4 patients undergone SLAP2, while prolapse recurrence occurred, respectively, in 4 and 2 patients. No major intraoperative complications occurred. An emergency reintervention for postoperative bleeding occurred in 13 cases undergone SLAP1 and in 5 patients treated with SLAP2. Fecal incontinence occurred in 8 and 4 cases of patients treated with SLAP1 and SLAP2. Conclusions: The combination of a simple hemorrhoidectomy to a mucosal rectal prolapsectomy should be part of every coloproctologist background. Promising and satisfying results can be achieved using SLAP for HD associated with asymmetric prolapse. Keywords: asymmetric prolapse; hemorrhoidal disease; hemorrhoidectomy; hemorrhoidopexy; muco-prolapsectomy.

Obstructive sleep apnea syndrome (OSAS) is prevalent among morbidly obese patients. Evaluation of the specific effects of sleeve gastrectomy (SG) on upper airway function has not been reported. Given the possibility that some patients will not respond despite weight loss, no studies have investigated whether other mechanisms may be responsible for persistent OSAS after bariatric surgery.To evaluate by subjective and objective assessment the impact of SG on upper respiratory physiology in the long-term.University Hospital, Division of Bariatric and ENT Surgery, in Italy.Thirty-six consecutive patients with OSAS who underwent laparoscopic SG were prospectively enrolled. The effect of SG on respiratory function and OSAS was followed for 5 years.All patients completed the 5-year follow-up. A significant (P.001) improvement in modified Epworth Sleepiness Scale questionnaire (ESS) was obtained in 91.6% (33/36) of patients. The Apnea/Hypopnea index (AHI) improved in 80.6% (29/36) of patients after surgery (from 32.8 ± 1.7 to 5.8 ± 1.2 (P.001), 4.9 ± 1.7). The remaining 19.4% (7/36) of patients with a positive ESS and/or AHI all had an associated respiratory resistance due to nasal obstructive diseases.SG improved OSAS overall, but patients who did not improve or only partially improved despite weight loss were found to have an associated nasal responsible pathology. How these patients will respond to nasal surgery and whether a 2-step procedure should be recommended for OSAS patients requires further study.

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.

Introduction: Bariatric surgery leads to rapid weight loss, a well-known risk factor for gallstone formation. Postoperative biliary complication rate requiring cholecystectomy is between 0.9 and 7.5% after laparoscopic sleeve gastrectomy and between 6 and 50% after laparoscopic gastric bypass. Several authors recommended ursodeoxycholic acid (UDCA) administration to reduce gallstone formation after diet-induced weight reduction. The aim of this randomized monocentric study is to evaluate gallstone incidence after prophylactic administration of UDCA in patients undergoing one anastomosis gastric bypass (OAGB). Methods: Patients undergoing OAGB were prospectively randomized into 2 groups: the UDCA group receiving oral UDCA 600mg/days for 6months in the immediate postoperative days, and the control group not administered with UDCA. Each group included 95 patients. Abdominal ultrasound, clinical evaluation, and quality of life scoring with Gastrointestinal Quality of Life Index (GIQLI) were performed postoperatively in all patients at 3, 6, and 12months. Results: At 12months of postoperative follow-up, 4 (4.2%) and 24 patients (25.2%) showed gallstones in the UDCA group and control group, respectively (p < 0.05). Among those who developed gallstones, 8 (28.6%) cases were symptomatic whereas 20 (71.4%) did not show any symptom. No statistically significant difference in GIQLI score between the two groups was found. Conclusion: OAGB, as other malabsorbent procedures, appears to have higher rate of cholelithiasis than purely restrictive procedures. In our prospective randomized controlled study, a regular postoperative UDCA intake during the first 6months seems to significantly reduce cholelithiasis incidence after OAGB, with no case of intolerance reported. Further studies are needed to assess this issue.

The pelvic floor is a complex anatomical entity and its neuromuscular assessment is evaluated through debated neurophysiological tests. An innovative approach is the study of pelvic floor through dynamic transperineal ultrasound (DTU). The aim of this study is to evaluate DTU sensitivity in recognizing patients with fecal incontinence and to evaluate its concordance with the results of the motor latency studied via pudendal nerve terminal motor latency (PNTML). Female patients affected by FI addressed to our center of coloproctology were prospectively assessed. After a coloproctological evaluation, comprising the PNTML assessment to identify pudendal neuropathy, patients were addressed to DTU to determine anterior and posterior displacement of puborectalis muscle by a blinded coloproctologist. In order to compare the data, a cohort of female healthy volunteers was enrolled. Sixty-eight subjects (34 patients and 34 healthy volunteers) were enrolled. The sensitivities of anterior displacement, posterior displacement and either anterior or posterior displacement in determining the fecal incontinence were 82%, 67% and 91%, respectively. A further high correlation of either anterior or posterior displacement with PTNML was also noted (88%). DTU is an indirect, painless and reproducible method for the identification of the pelvic floor neuromuscular integrity. Its findings seem to highly correlate with FI symptoms and with PNTML results. In the near future, after larger comparative studies, DTU would be considered a potential reliable non-invasive and feasible indirect procedure in the identification of fecal incontinence by pudendal neuropathy. Trial registration number is NCT03933683.

Pelvic floor rehabilitation aims to address perineal functional and anatomic alterations as well as thoraco-abdominal mechanic dysfunctions leading to procto-urologic diseases like constipation, fecal and urinary incontinence, and pelvic pain. They require a multidimensional approach, with a significant impact on patients quality of life. An exhaustive clinical and instrumental protocol to assess defecation disorders should include clinical and instrumental evaluation as well as several clinical/physiatric parameters. All these parameters must be considered in order to recognize and define any potential factor playing a role in the functional aspects of incontinence, constipation and pelvic pain. After such evaluation, having precisely identified any thoraco-abdomino-perineal anatomic and functional alterations, a pelvi-perineal rehabilitation program can be carried out to correct the abovementioned alterations and to obtain clinical improvement. The success of the rehabilitative process is linked to several factors such as a careful evaluation of the patient, aimed to select the most appropriate and specific targeted rehabilitative therapy, the therapist’s scrupulous hard work, especially as regards the patient’s emotional and psychic state, and finally the patient’s compliance in undertaking the therapy itself, especially at home. These factors may deeply influence the overall outcomes of the rehabilitative therapies, ranging from “real” success to illusion “myth”. RESUMO A reabilitação do assoalho pélvico visa abordar alterações funcionais e anatômicas perineais, bem como disfunções mecânicas torácicas-abdominais que levam a doenças procto-urológicas como prisão de ventre, incontinência fecal e urinária e dor pélvica. Requerem uma abordagem multidimensional, com impacto significativo na qualidade de vida dos pacientes. Um protocolo clínico e instrumental exaustivo para avaliar os transtornos de defecação deve incluir avaliação clínica e instrumental, bem como diversos parâmetros clínicos/fisiátricos. Todos esses parâmetros devem ser considerados para reconhecer e definir qualquer fator potencial desempenhando um papel nos aspectos funcionais da incontinência, prisão de ventre e dor pélvica. Após tal avaliação, tendo identificado com precisão quaisquer alterações anatômicas e funcionais tóraco-abdomino-perineais, um programa de reabilitação pelvi-perineal pode ser realizado para corrigir as alterações acima mencionadas e obter melhora clínica. O sucesso do processo de reabilitação está ligado a diversos fatores, como uma avaliação cuidadosa do paciente, visando selecionar a terapia de reabilitação direcionada mais adequada e específica, além do trabalho árduo e escrupuloso do terapeuta, especialmente no que diz respeito ao estado emocional e psíquico do paciente e, finalmente, a conformidade do paciente em realizar a terapia em si, especialmente em casa. Esses fatores podem influenciar profundamente os resultados globais das terapias de reabilitação, que vão desde o sucesso “real” até o “mito” ilusório.

Backgrounds. One of the major complications after laparoscopic sleeve gastrectomy (LSG) is represented by leaks along the staple line. Several reinforcement techniques have been proposed, but scarce data about the real strengthening offered are present. Thus, we aimed to evaluate if different reinforcements produced different bursting pressures after LSG, and then to verify if the clinical application of the stronger reinforcement produced a reduction in leakage rate. Methods. We prospectively enrolled all consecutive obese patients that underwent LSG. We tested 3 different types of staple lines, as follows: group 1, no reinforcement; group 2, bioabsorbable buttress reinforcement; group 3, invaginating overrunning barbed suture. A burst pressure test was applied to the gastric specimen by means of high-resolution manometric catheter. After burst pressure tests, a subsequent consecutive series of patients were treated with the most effective reinforcement, and rate of leaks was recorded. Results. We enrolled in total 110 obese patients; 20 patients for each group of staple line reinforcement and then other 50 consecutive patients underwent LSG with the higher burst pressure staple line reinforcement. Median burst pressures were similar in group 1 and group 2; group 3 showed a statistically significant pressure increase ( P < .0001) than group 1 and group 2, with a 5.2-fold value. Other consecutive 50 obese patients underwent LSG with overrunning reinforcement. In none of them a leak was detected. Conclusions. Reinforcement of the SG staple line, with overrunning suture, seems to drastically increase bursting pressures in an ex vivo model and it is promising when reproduced in vivo.

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.

BACKGROUND Intersphincteric injectable bulking agents are one of the current treatment options for fecal incontinence, failing behavioral and medical therapy. Gatekeeper showed promising short-term results, but long-term outcomes are unknown. OBJECTIVE The purpose of this study was to clinically evaluate a prospective cohort of fecal incontinence patients up to 36 months after implantation of Gatekeeper. DESIGN This was a prospective clinical study. SETTINGS The study was conducted at a large university tertiary care hospital. PATIENTS Consecutive female patients were eligible if fecal incontinence onset was ≥6 months before the first visit and symptoms were refractory to standard conservative measures. INTERVENTIONS All of the patients underwent implantation of 4 or 6 Gatekeeper prostheses. Three-dimensional endoanal ultrasonography and high-resolution anorectal manometry were performed preoperatively and postoperatively at 2 and 3 months after implantation. MAIN OUTCOME MEASURES The Cleveland Clinic Fecal Incontinence score was calculated at baseline and 1, 3, 12, 24, and 36 months postoperatively. RESULTS Twenty patients (all women; median age, 59 y) were enrolled, and all implants were uneventful. Postoperative endoanal ultrasonography showed normal prosthesis localization in 16 patients (80%). At manometry, mean anal resting pressure significantly improved (57.8 ± 7.5 mm Hg; p = 0.0004). Mean preoperative Cleveland Clinic Fecal Incontinence score was 12.4 ± 1.8, with significant improvements initially documented at 3 months (4.9 ± 1.5; p < 0.0001) and sustained up to 36 months (4.9 ± 1.7; p < 0.0001). Patients receiving only 4 (compared with 6) prostheses and those experiencing pudendal neuropathy (compared with those who did not) showed significantly higher Cleveland Clinic Fecal Incontinence score values in the middle term. LIMITATIONS The study was limited by its small sample size and absence of quality-of-life data. CONCLUSIONS Initial improvements after Gatekeeper implantation for fecal incontinence are sustained in the middle term. Accurate preoperative evaluation of coexistent clinical conditions that may negatively affect outcomes is recommended for patient selection. See Video Abstract at http://links.lww.com/DCR/B109.

La puntuacion media preoperatoria de la incontinencia fecal de la Cleveland Clinic, fue de 12.35 ± 1.75, con mejoras significativas documentadas inicialmente a los 3 meses (4.9 ± 1.5, p

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.

Hemorrhoidal disease (HD) treatment still remains controversial. In fact, despite many surgical progresses, postoperative pain, and discomfort remain the major weaknesses. Laser hemorrhoidoplasty (LHP) is a minimal invasive procedure for HD treatment determining the shrinkage of the hemorrhoidal piles by diode laser. The aim of the current study is to analyze the feasibility and efficacy of LHP in patients with II–III degrees hemorrhoids. Consecutive patients with II–III degree hemorrhoids were enrolled in the study and underwent an LHP treatment using a 1470-nm diode laser. Operative time, postoperative pain and complications, resolution of symptoms, and length of return to daily activity were prospectively evaluated. Recurrence of prolapsed hemorrhoid or symptoms at a minimum follow-up of 6months was evaluated. Fifty patients (28 males and 22 females) were enrolled in the study. No significant intraoperative complications occurred. Postoperative pain score (at 12, 18, and 24h postoperatively), evaluated through visual analogue scale, was extremely low (mean value 2). No postoperative spontaneous bleeding occurred. The 100% of our population came back to daily activity 2 days after surgery. At a mean follow-up period of 8.6months, we reported a recurrence rate of 0%. LHP demonstrated a large efficacy in selected patients. The greatest strength points were low postoperative pain, the presence of slightly significant peri-anal wounds, no special anal hygienic measures and low surgical time. Thus, resulting in a negligible postoperative discomfort, LHP could be considered a painless and minimal invasive technique in the treatment of HD.

Background and Aims: While in the past, thoracotomy represented the traditional surgical approach for the treatment of epiphrenic diverticula, actually mini-invasive approach seems to be the preferred treatment as many series have been published in the recent years. This article describes the authors’ experience with the laparoscopic approach for performing diverticulectomy, myotomy, and Nissen–Rossetti fundoplication. Material and Methods: From 1994 to 2010, 21 patients (10 men and 11 women), mean age 58.5 years (range 45–74 years), with symptomatic epiphrenic diverticulum underwent laparoscopic diverticulectomy, myotomy and Nissen–Rossetti fundoplication. Results: The mean operative time was 135 min (range = 105–190 min). Mean hospital stay was 14.2 days (range = 7–25 days). In 5 patients (23.8%), a partial suture staple line leak was observed. Conservative treatment achieved leak resolution in all the cases. One patient (4.8%) died of a myocardial infarction in the postoperative period. After a mean clinical follow-up period of 78 months (range = 6–192 months), excellent or good outcome was referred with no dysphagia in 16 patients (80%) and only mild occasional dysphagia in 4 patients (20%). Conclusions: Surgical treatment of epiphrenic diverticula remains a challenging procedure also by mini-invasive approach, with major morbidity and mortality rates. For this reason, indications must be restricted only to selected and symptomatic patients in specialized centers.

Background Nutrient interaction with the mid-gut may play a role in improving type 2 diabetes mellitus (T2D) after bariatric surgery. However, Roux-en-Y gastric bypass, biliopancreatic diversion, and sleeve gastrectomy include diversion of food from the duodenum and/or partial gastrectomy. Biliointestinal bypass (BIBP) was introduced to eliminate the major side effects of jejunoileal bypass. It does not involve any change to the anatomy of the stomach or the duodenum. A prospective evaluation of the role of BIBP in glycemic control has not been reported. Objectives Longitudinal evaluation of T2D after BIBP. Setting University hospitals in Europe and Canada. Method The effects of BIBP on metabolism and glycemia in 28 consecutive patients with T2D were evaluated over 2 years. Results Decreases (P

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.

BACKGROUND: Studies have demonstrated that Nissen fundoplication controls acid gastroesophageal reflux (GER). Combined 24-h pH and multichannel intraluminal impedance (MII-pH) allows detection of both acid and nonacid GER. Antireflux surgery is considered for any patient whose medical therapy is not efficient, particularly patients with nonacid gastroesophageal reflux disease (GERD). Nevertheless, fundoplication used to control nonacid reflux has not been reported to date. METHODS: In this study, 15 consecutive patients who underwent laparoscopic Nissen-Rossetti fundoplication had MII-pH both before and after the surgical procedure. The numbers of acid and nonacid GER episodes were calculated with the patient in both upright and recumbent positions. RESULTS: The 24-h pH monitoring confirmed the postoperative reduction of exposure to acid (p < 0.05). Postoperatively, the total, acid, and nonacid numbers of GER episodes were reduced (p < 0.05). CONCLUSION: According to the findings, MII-pH is feasible and well tolerated. It provides an objective means for evaluating the effectiveness of Nissen-Rossetti fundoplication in controlling both acid and nonacid GER

No studies have examined scars and quality of life after different treatments of wound dehiscence in patients undergoing post-bariatric abdominoplasty. Scars and quality of life of patients with postoperative wound dehiscence managed with negative pressure wound therapy (group A) and conventional wound therapy (group B) were reviewed 6 months after wound healing. Of 38 patients undergoing treatment for wound dehiscence after 203 abdominoplasty, 35 (group A = 14 versus group B = 21) entered the study. Wound healing in group A was significantly faster than group B (P = 0·001). Patients (P = 0·0001) and observers (P = 0·0001) reported better overall opinions on a scar assessment scale for group A. Better overall quality of life and general health satisfaction were observed in group A (P < 0·05). A significant correlation was observed between the World Health Organization Quality of Life scores and Patient and Observer Scar Assessment Scale scores (r=-0·68, P < 0·0001) in all 35 patients. Negative pressure wound therapy is feasible and effective in patients with wound dehiscence following post-bariatric abdominoplasty. An adequate post-treatment outcome is achieved compared with conventional wound therapy in light of a strong association found between worse patient scar self-assessment and poor overall quality of life, regardless of the received treatment.

INTRODUCTION: Few cases of laparoscopic total gastrectomy have been published. Reconstruction of the digestive tract was generally accomplished with a Roux-en-y esophagojejunal mechanical anastomosis. Here we report the first 2 cases of laparoscopic conversion of an omega in a Roux-en-y reconstruction due to the occurrence of a severe alkaline esophagitis after mini-invasive total gastrectomy for cancer. MATERIALS AND METHODS: Two male patients presented in 2004. One year prior, at another facility, they had undergone laparoscopic total gastrectomy for cancer, with reconstruction of digestive tract by means of an esophagojejeunostomy with a jejunal loop and Braun's side-to-side enteroanastomosis. They complained of daily symptoms of nausea, regurgitation, heartburn, and early postprandial fullness with reduction of appetite and weight loss of almost 15 kg. Instrumental examination diagnosed alkaline esophagitis. Intervention was performed via laparoscopic approach and the digestive reconstruction was reconfigured in a Roux-en-y type with a proximal limb of almost 60 cm. RESULTS: Operative time was 135 to 180 minutes. No postoperative complications occurred. After 1-year follow-up, symptoms resolution and esophagitis healing have been observed in both patients. CONCLUSIONS: Laparoscopic gastrectomy is gaining wide acceptance. In our opinion, a standardization of the technique is necessary: we believe Roux-en-y should be considered the preferred reconstruction route ensuring the best protection of the esophagus from alkaline reflux

Background Fecal incontinence (FI) is a common condition that has devastating consequences for patients’ QOL. In some patients, the conventional functional pelvic floor electrical stimulation has been effective but is an invasive and embarrassing treatment. The object of the study was to evaluate the feasibility of functional extracorporeal magnetic stimulation (FMS) in strengthening the pelvic floor muscles without an anal plug and the embarrassment of undressing. Materials and Methods Thirty patients (26 female and 4 males) with FI were enrolled. All patients were assessed during a specialized coloproctology evaluation followed by endoanal ultrasonography and anorectal manometry. All patients underwent an FMS treatment once weekly for 8 weeks. Patients’ outcome was assessed by the Cleveland Clinic Fecal Incontinence Score (CCFIS) and by the fecal incontinence QOL questionnaire (FIQL). Results After 8 weeks, the number of solid and liquid stool leakage per week was significantly reduced (p Conclusion FMS is a safe, non-invasive and painless treatment for FI. It could be recommended for selected patients with non-surgical FI to ensure a rapid clinical improvement.

Background: Esophageal cancer is associated with a poor long-term prognosis. Only a 10% 5-year survival rate is reported. This article aims to evaluate the feasibility and efficacy of laparoscopic esophagectomy for the palliative treatment of advanced esophageal cancer (T3-T4 Nx-N1) after neoadjuvant therapy. Methods: From March 1998 to July 2002, 35 patients (mean age, 64.6 years; range, 35–72 years) affected by advanced cancer of the middle lower third of the esophagus came to the authors’ observation. All received neoadjuvant radiochemotherapy. Of the 35 patients, 22 (62.9%) showed a positive response to treatment (‡50% reduction of maximal cross-sectional area of the tumor), and surgical intervention was performed 4 weeks after the end of the therapy. The operations were accomplished through the laparoscopic approach and left lateral cervicotomy. Results: The mean operative time was 160 min (range, 120–260 min). One patient (4.5%) experienced a cervical anastomotic leak. Three patients (13.6%) died in the postoperative period: one of myocardial infarction and two of acute respiratory failure. The mean postoperative hospital stay was 12.1 days (range, 9–23 days). After a mean follow-up period of 20.2 months (range, 10–40 months), 13 patients (68.4%) were alive. Conclusions: The laparoscopic approach seems to be effective for the palliative treatment of advanced esophageal cancer. Further trials will be necessary to evaluate the advantages of this technique.

BACKGROUND: Hemostasis during thyroidectomy is essential; however, the safest, most efficient, and most cost-effective way to achieve this is unclear. This randomized, multicenter, single-blind, prospective study evaluated the efficacy and safety of using different hemostatic approaches in patients undergoing total thyroidectomy. METHODS: Patients aged ≥18 to 70 years were randomized to Floseal + a harmonic scalpel (HS), Floseal alone, HS alone, or standard total thyroidectomy. Primary endpoint was 24-hour drain output. Secondary endpoints included surgery duration and complications. RESULTS: Two hundred and six patients were randomized to Floseal + HS (n = 52), Floseal alone (n = 54), HS alone (n = 50), and standard total thyroidectomy (n = 50). The 24-hour drain output was lower in the Floseal + HS group compared with standard thyroidectomy. Floseal + HS also had a shorter surgery time (P < .0001) versus the other 3 treatments. CONCLUSION: Floseal + HS can be effective at reducing postsurgical drain output and provides a complementary hemostatic approach in patients undergoing total thyroidectomy. © The Author(s) 2015.

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.

Objective To define the frequency and predictors of short esophagus in a case series of patients undergoing antireflux surgery. Method An observational prospective study from September 10, 2004, to October 31, 2006, was performed at 8 centers. The distance between the esophagogastric junction as identified by intraoperative esophagoscopy and the apex of the diaphragmatic hiatus was measured intraoperatively before and after esophageal mediastinal dissection; a distance of 1.5 cm was arbitrarily determined to categorize cases as long (>1.5 cm) or short (≤1.5 cm). Results One hundred eighty patients were enrolled; the mean age of patients was 49.3 ± 15.3 years. At the first measurement (after isolation of the esophagogastric junction), the median distance between the esophagogastric junction and the apex of the hiatus was equal to or shorter than 1.5 cm in 68 (37.7%) patients; at the second measurement (after full mediastinal isolation), the measurement of the distance was still shorter than 1.5 cm in 34 (18.8%) patients and between 1.5 and 2.5 cm in 24 (13.4%) patients. The median length of the mediastinal esophageal dissection was 6 cm (range 1–12 cm). An esophageal lengthening procedure was performed in 26 (14.4%) patients. The duration of symptoms ( P = .047), the General Health domain of the SF-36 questionnaire ( P = .001), and an x-ray barium swallow ( P = .000) are predictive factors for a “true” short esophagus. Conclusions True short esophagus is present in about 20% of patients undergoing routine antireflux surgery. Radiology, severity, and duration of symptoms are predictors of true foreshortening.

Dear Editor: Low transsphincteric fistula (LTF) is a tedious surgical disease and its treatment relies on several conventional strategies among which the most common are fistulotomy and fistulectomy. Fistulotomy consists of leaving the anal wound open but is reported to be associated with prolonged wound healing, anal deformity, and an altered continence. In light of these findings, at the end of the 1980s, authors have described a technique based on the marsupialization of wound edges to leave less raw unepithelialized tissues to heal over. Previous randomized studies have compared the outcomes of marsupialization and open wounds in the treatment of anal fistula. To date, no study has specifically compared postoperative care management and recurrence in patients who underwent fistulotomy with or without marsupialization for LTF. In this letter, we compared shortand long-term outcomes of patients with LTF undergoing fistulotomy with those of patients undergoing fistulotomy with marsupialization in the same period. From December 2007 to October 2013, consecutive patients with a diagnosis of anal fistula referred to our surgical uni t , who underwent f is tulectomy with marsupialization (M) or with open wound (OW) on a 1.5:1 ratio over a 7-year period, were prospectively enrolled. At the baseline, all patients underwent anal manometry and endoanal ultrasound. Low transsphincteric anal fistula was defined as a fistula tract traversing the lower third of the external anal sphincter at preoperative instrumental evaluation and confirmed intra-operatively. Patient follow-up was based on regular outpatient clinic visits every 3 months, and information obtained from medical records, correspondence, and telephone contact. Postoperative pain was evaluated with the visual analogue scale (VAS) 12 and 24 h after surgery. Wound healing was defined by complete re-epithelialization recorded by one independent observer who attended the outpatients’ visits and contacted the patients by phone every day afterwards to plan the final outpatient visit. Local wound care was assessed by recording the daily frequency of dressing change or even need for and frequency of who (Bmy-self^; family; district nurse) performed it . Dressing change was strictly performed only at the three daily dressing assessments (every 8 h–7 a.m., 3 p.m., and 11 p.m.), only in case the dressing appeared moist and not absolutely clean and dry. This was recorded bymeans of diaries the patients were asked to complete. In addition, wound care was monitored during outpatient follow-up visits until the wound was closed or up to 3 months after dismissal from the hospital. Wound infection was defined as the presence of local symptoms of suppuration with or without an isolated pathogenic microorganism. A recurrent fistula was assessed by clinical examination and 3D endoanal ultrasound at the outpatient clinic by a competent observer, independent from the operating team. Recurrence was defined when symptoms of the disease recurred after an interval following complete wound healing. Two hundred and sixty-eight consecutive patients with a diagnosis of anal fistula were admitted in our department. Seventythree of 268 consecutive patients with a low transsphincteric anal fistula entered the study. Forty patients were male (male/female ratio 1:2), and the median age at the time of diagnosis was 41 (31–68) years. Forty-four patients (60.2 %) had a marsupialization (M group) and 29 had an open wound (OW group). The median operating time was higher in the M group (P=0.0001). Wound bleeding was less frequent in the marsupialization group than in the OW group (16 vs. 48%, P= * Paolo Limongelli limpao@libero.it

Identifying and treating patients with extra-esophageal symptoms is a challenge. When the patient is unable to control his symptoms with pharmacological therapy alone, anti-reflux surgery may be indicated. This study aims to evaluate the outcomes of total fundoplication in the resolution of extra-esophageal manifestations and verify changes in 24-h MII-pH monitoring before and after surgery. From October 2005 to October 2010, patients who reported respiratory symptoms, possibly related to GERD, have been sent to our Institute. All patients were practiced ambulatory 24-h MII-pH before and after surgery. Thirty-five patients selected for the antireflux surgery have undergone all the same surgical procedures. Data were collected prospectively at 6 and 12 months after laparoscopic fundoplication. After laparoscopic fundoplication, the total percentage of exposure time with esophageal pH < 4, and both in upright and supine position was very low. A statistically significant difference (p < 0.05) was found in the number of detected refluxes at MII and detected refluxes at MII 15-cm segment in pre and post-operative period. Symptom relief was obtained in all patients. Laparoscopic fundoplication is a safe and effective procedure to protect from refractory GERD and extra-esophageal symptoms, when evaluated with a thorough pre-operative selection.

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.

ntroduction: Although its excellent results, laparoscopic sleeve gastrectomy (LSG) presents major complications ranging from 0% to 29%. Among them, the staple line leak presents an incidence varying from 0% to 7%. Many trials debated about different solutions in order to reduce leaks??? incidence. No author has investigated the role of gastric decompression in the prevention of this complication. Aim of our work is to evaluate if this procedure can play a role in avoiding the occurrence of staple line leaks after LSG. Materials and Methods: Between January 2008 and November 2012, 145 patients were prospectively and randomly included in the study. Seventy patients composed the group A, whose operations were completed with placement of nasogastric tube; the other 75 patients were included in the group B, in which no nasogastric tube was placed. Results: No statistical differences were observed between group A and group B regarding gender distribution, age, weight, and BMI. No intraoperative complications and no conversion occurred in both groups. Intraoperative blood loss (50.1 ± 42.3 vs. 52.5 ± 37.6 ml, respectively) and operative time (65.4 ± 25.5 vs. 62.6 ± 27.8 min, respectively) were comparable between the two groups (p: NS). One staple line leak (1.4%) occurred on 6th postoperative day in group A patients. No leak was observed in group B patients. Postoperative hospital stay was significantly longer in group A vs. group B patients (7.6 ± 3.4 vs. 6.2 ± 3.1 days, respectively, p: 0.04). Conclusions: Routine placement of nasogastric tube in patients operated of LSG seems not useful in reducing leaks??? incidence.

"Background: Preoperative chemoradiotherapy (CRT) improves the survival of patients with oesophageal cancer when compared with surgery alone.. . Methods: We conducted a phase II, multicenter trial of FOLFOX-4 and cetuximab in patients with locally advanced oesophageal cancer (LAEC) followed by daily radiotherapy (180 cGy fractions to 5040 cGy) with concurrent weekly cetuximab. Cytokines levels potentially related to cetuximab efficacy were assessed using multiplex-bead assays and enzyme-linked immunosorbent assay at baseline, at week 8 and at week 17. Primary end point was complete pathological response rate (pCR).. . Results: In all, 41 patients were enroled. Among 30 patients who underwent surgery, a pCR was observed in 8 patients corresponding to a rate of 27%. The most frequent grade 3\/4 toxicity was skin (30%) and neutropenia (30%). The 36-month survival rates were 85 and 52% in patients with pathological CR or PR vs 38 and 33% in patients with SD or PD.. . Conclusions: Incorporating cetuximab into a preoperative regimen for LAEC is feasible; no correlation between cytokines changes and patient outcome was observed. Positron emission tomography\/computed tomography study even if influenced by the small number of patients appears to be able to predict patients outcome both as early and late metabolic response.. .

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.

Introduction Although laparoscopic Nissen fundoplication has been recognized as the standard of care for hiatal hernia (HH) repair, HH recurrence due to breakdown of the hiatoplasty have been reported as a common mechanism of failure after primary repair. Different surgical techniques for diaphragmatic pillars closure have been proposed, but the problem remains unsolved. The authors hypothesized that ultrastructural illness may be implicated in this recurrence. The aim of this study was to investigate the presence of changes at esophageal hiatal area in patients with and without HH. Materials and Methods One hundred and thirty-two laparoscopic samples from phrenoesophageal membrane and diaphragmatic crura were collected from 33 patients with gastroesophageal reflux disease and HH (HH group) and 60 samples from 15 patients without HH enrolled as the control group (NHH group). All specimens were processed and analyzed by transmission electron microscopy. Results Muscular and connective samples from the NHH group showed no ultrastructural alterations; similar results were found in phrenoesophageal ligament samples from the HH group. In contrast, 94% of the muscular samples obtained from the crura of the HH group have documented four main types of alterations. In 75% of HH patients, the pillar lesions were severe. Conclusion Patients with hiatal hernia have ultrastructural abnormalities at the muscular tissue of the crura that are not present in patients with a normal gastroesophageal junction. There is no difference in the microscopic damage at the connective tissue of the phrenoesophageal membrane surrounding the esophagus of the two groups of patients. The outcome of antireflux surgery could depend not only on the adopted surgical technique but also on the underlying status of the diaphragmatic crura.

One limit of the Roux-en-Y gastric bypass (GBP) is the preclusion of exploring the bypassed stomach with conventional endoscopy and radiological studies. In this study, we explored the feasibility, safety, and weight progression of a new bariatric procedure that eliminates this inconvenience. Eleven 40- to 50-kg Yorkshire pigs underwent laparoscopic sleeve gastrectomy and Roux-en-Y duodeno-jejunal bypass (SG-DJBP). Weight was monitored at postoperative days 15 and 30 and after 3 months; weight progression was compared with an identical group that underwent a sham procedure or GBP. At autopsy, surgical site was evaluated at microscopic and macroscopic level. Mean operating time was 66 ± 5.76 min. All the survivors tolerated the procedure well, except one subject that experienced a gastric leak from the stapler line. The SG-DJBP had a had significantly slower weight gains than the sham group (P = 0.005). The absence of histological abnormalities in the duodenal wall was confirmed at autopsy. SG-DJBP is feasible and produces effects of weight progression comparable to those of GBP. Being a combination of previously standardized procedures, we are confident to propose this procedure as a bariatric alternative in humans. Long-term follow-up will be required to establish the efficacy on weight loss in humans.

Background The realisation of bariatric surgery has to date modified the digestive process solely through procedures within the abdominal cavity. However, endocrine surgeons have recently demonstrated the feasibility of a minimally invasive approach to the neck. In this study, we explored the feasibility, safety and weight progression of a bariatric procedure performed at the neck. Methods Eleven 40–50 kg Yorkshire pigs underwent endoscopic placement of an adjustable band to the cervical esophagus (ECB). Weight was monitored at postoperative days 15, 30, and after 7 weeks; weight progression was compared with an identical group of pigs who underwent a sham procedure. At autopsy, the surgical site was evaluated in a microscopic and macroscopic manner. Results Mean operating time was 66±5.76 min. All pigs tolerated the procedure well, except one subject that experienced food intolerance. The ECB group experienced significantly slower weight gain than the sham group (P= 0.005). Proper location of the band and absence of microscopic lesions at the esophageal wall were confirmed at autopsy and pathological examination. Conclusion Bariatric surgery at the neck is feasible and produces effects on weight reduction. Further refinements and longer observation periods are required to propose this procedure as safe and effective alternative in humans.

SUMMARY. The aim of this study is to evaluate if esophageal dysmotility can influence the outcome of laparoscopic total fundoplication for gatro-esophageal reflux disease (GERD). The advent of laparoscopic fundoplication has greatly reduced the morbidity of antireflux surgery and by now, it should be considered the surgical treatment of choice for GERD. Some authors assert that total versus partial fundoplication should improve the rate of postoperative dysphagia or gas bloat syndrome, particularly in patients with esophageal dysmotility. From September 1992 to December 2005, 420 consecutive patients 171 male and 249 female, mean age 42.8 years (range 12–80) underwent laparoscopic Nissen-Rossetti fundoplication. At manometric evaluation, we divided patients into two groups: group A (163/420; 38.8%) with impaired esophageal peristalsis (peristaltic waves with a pressure

Background We investigated which factors are significantly associated with long-term quality of life after laparoscopic total fundoplication in the treatment of gastroesophageal reflux disease. Methods Patients (n = 144) were given a standardized frequency-intensity symptoms questionnaire and the Short-Form 36 Health Survey for quality-of-life evaluation before and after laparoscopic total fundoplication. Results At follow-up evaluation (n = 102), patients had a significant reduction in their symptoms score and no deterioration in quality of life. A significant association with postoperative dysphagia for solids and/or liquids was found in the physical component summary score of the Short-Form 36 administered to patients postoperatively ( P = .003). Conclusions In this study, laparoscopic total fundoplication was a safe and effective surgical treatment for gastroesophageal reflux disease, generally offering an improved long-term quality of life, with the exception of a minority of patients (6 of 102 patients; 5.8%) who experienced persistent severe dysphagia.

Introduction Selecting gastroesophageal reflux disease (GERD) patients for surgery on the basis of standard 24-h pH monitoring may be challenging, particularly if this investigation does not correlate with clinical symptoms. Combined multichannel intraluminal impedance pH monitoring (MII-pH) is able to physically detect each episode of intraesophageal bolus movements, enabling identification of either acid or non-acid reflux episodes and thus establish the association of the reflux with symptoms. Materials and Methods We prospectively assessed and reviewed data from 314 consecutive patients who underwentMII-pH for GERD not responsive or not compliant to proton pump inhibitor therapy. One hundred fifty-three patients with aminimumfollowup of 1 year constituted the study population. Clinical outcomes and satisfaction rate were collected in all patients who underwent laparoscopic Nissen–Rossetti fundoplication. Outcomes were reported for patients with normal and ineffective peristalsis and for patients with positive pHmonitoring, negative pHmonitoring and positive total number of reflux episodes atMII, and negative pH monitoring and normal number of reflux episodes at MII and a positive symptom index correlation with MII. Results The overall patient satisfaction rate was 98.3%. No differences were recorded in the clinical outcomes of the patients with preoperative normal and ineffective peristalsis. No differences in patients’ satisfaction and clinical postoperative DeMeester symptom scoring system were noted between the groups as determined by MII-pH. Conclusion MII-pH provides useful information for objective selection of patients to antireflux surgery. Nissen fundoplication provides excellent outcomes in patients with positive and negative pH and positive MII monitoring or Symptom Index association. More extensive studies are needed to definitively standardize the useful MII-pH parameters to select the patient to antireflux surgery

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.
