Crural closure in addition to laparoscopic sleeve gastrectomy (LSG) represents a valuable option for the synchronous management of morbid obesity and hiatal defects, providing good outcomes in terms of weight loss and gastroesophageal reflux disease (GERD) symptoms control. The aim of this prospective study was to evaluate the safety and effectiveness of the reinforced cruroplasty during LSG compared with a concurrent group of simple cruroplasty.The study groups included 96 morbidly obese patients who underwent simultaneous LSG and cruroplasty. Group A: 48 patients with hiatal areal defect4 cm(2) and normal pillars (simple posterior cruroplasty); group B: 48 patients with hiatal areal defect4 and8 cm(2) with weakness of the right pillar (on-lay synthetic absorbable mesh-reinforced cruroplasty). Upper GI symptoms were assessed by Roma III standard questionnaire. Endoscopy, imaging, esophageal 24-h pH monitoring and HR manometry were performed in cases of persistent or recurrent symptoms after surgery.Mortality rate was nil. The conversion rate to open was 1 %. Intra-operative diagnosis of hiatal hernia occured in 41 patients (42.7 %). Mesh-related complications were none. Perioperative complications occurred in four patients (4.1 %). After 19- to 21-month follow-up, GERD symptom remission occurred in 89 % of patients. GERD symptoms were detected postoperatively in eight patients: six in group A (five symptomatic and radiological recurrences and one persistent) and two in group B (one persistent and one de novo GERD) (P 0.05).The synthetic absorbable mesh offers an effective option for crural repair during LSG with no clinical recurrences at 19 months. The midterm results of this prospective comparative study evaluating two different technical options for cruroplasty confirm that the simultaneous procedures are safe and cruroplasty is effective in mild-to-moderate GERD control .

Laparoscopic adjustable silicone gastric banding (LAGB) was the first bariatric procedure to be performed by a laparoscopic approach. Introduction of LAGB into clinical practice was an immediate success in Europe as well as in Australia. Although sleeve gastrectomy, standard Roux-en-Y gastric bypass (RYGBP), and biliopancreatic diversion with duodenal switch (BPD-DS) currently represent the majority of laparoscopic bariatric/metabolic procedures in the United States and Canada, laparoscopic gastric banding during the last 10 years has been growing acceptance by physicians as well as by patients. The idea behind the operation is to “create” a small pouch in the upper part of the stomach with a controlled and adjustable stoma, without stapling, thus limiting the daily food intake (restrictive procedure). The silicone prosthesis is placed around the stomach just below the gastroesophageal junction, creating a 15–20 mL pouch (virtual pouch) (Fig. 2.1). This operation does not involve neither rerouting of food through the upper gastrointestinal tract nor exclusion of intestinal segments. The weight loss process in the short and long term is due to the food intake restriction and early satiety. In the highest quality study, excess body weight loss at 1 year after LAGB is 48%. At this time the hypertension, diabetes, dyslipidemia, and sleep apnea resolution rate were about 55%, 58%, 42%, and 45%, respectively [1]. The LAGB represents the bariatric procedure with the lower reported incidence of short- and midterm adverse events [2–4]; however, long-term data show a higher incidence of postoperative acute complications leading to band repositioning or removal and eventually conversion to other procedures [5–7].

The aims of the study were to evaluate if multidetector computed tomography (MDCT) can be helpful and useful in the decision-making process in sleeve patients with gastroesophageal reflux disease (GERD) symptoms and to demonstrate the reproducibility and accuracy of the technique. Twenty-three patients submitted to laparoscopic sleeve gastrectomy (LSG), complaining upper gastrointestinal (GI) symptoms and/or weight regain and candidated to laparoscopic surgical revision were investigated. All patients underwent upper GI barium study, endoscopy, and MDCT for the identification of esophageal dilatation, neofundus development, thoracic sleeve migration, sleeve dilatation, and/or antrum dilatation. Selected patients underwent laparoscopic sleeve revision, cruroplasty, and/or fundectomy according to MDCT findings. Surgical findings were considered as “gold standard.” Symptom persistence or resolution was investigated after 6 months with a standard clinical questionnaire. A total of 21 patients with sleeve migration or dilatation and neofundus underwent laparoscopic revision. A strong correlation between MDCT preoperative findings and intraoperative findings was observed. The presence of sleeve migration was significantly underestimated by both conventional radiology and upper GI endoscopy (sensitivity of 57.1 and 50 %, respectively). Symptom remission was observed in 19 out of 21 patients at 6 months. In two cases, surgical revision was not indicated on the basis of MDCT findings. MDCT is more accurate than the conventional radiology and endoscopy for the detection of morphological alteration causing GERD symptoms after LSG and can be considered a valid noninvasive method to guide surgery and monitoring patients following revision.

Altered gastric anatomy following laparoscopic sleeve gastrectomy (LSG) is likely to induce upper gastrointestinal (GI) symptoms. Published studies, however, have focused mainly on gastroesophageal reflux disease (GERD). This study aims to evaluate LSG's impact on the prevalence of upper GI symptoms and to assess the effects of time from surgery, weight loss, and proton pump inhibitor (PPI) therapy.The validated Rome III Criteria symptom questionnaire for upper GI symptoms, including quality of life items, has been self-administered to 97 patients who underwent LSG. Symptoms were analyzed either separately or altogether to classify patients in GERD or dyspepsia, subdivided in epigastric pain (EPS) and post-prandial distress (PDS) syndromes.Before LSG, 52.7% of the patients were asymptomatic, 27.0% had GERD, and 8.1% had dyspepsia (2.7% EPS, 5.4% PDS). After a median follow-up of 13 months, 91.9% of the patients complained of upper GI symptoms, the most prevalent being PDS (59.4 %). GERD prevalence did not differ before and after LSG. The only symptom strongly related to LSG was dysphagia (OR 4.7, 95% CI 1.3-20.4, p = 0.015), which was present in 19.7% of the patients and mainly associated with PDS rather than GERD. GI symptoms, however, did not have a great impact on quality of life. Time from surgery, weight loss after surgery, as well as concomitant PPI, did not influence the symptoms.After a median follow-up of 13 months, PDS-like dyspepsia, rather than GERD, was the main complaint, both poorly responding to PPI therapy. A longer follow-up will be necessary to evaluate their future persistency.

Bariatric surgery represents the elective treatment of severe obesity (BMI≥40Kg/m2) since it results in better control of cardiovascular risk factors and comorbidities typically associated with obesity, like diabetes, hypertension and dyslipidemia. Obesity is a recognized independent risk factor for chronic kidney disease and for progression of renal insufficiency. Pathomechanisms are still incompletely known. Obesity is associated with hyper-filtration, microalbuminuria and proteinuria all of which favor renal disease and its progression. This narrative review reports on the available evidence linking bariatric surgery and renal function since this surgery may affect proteinuria, hyper-filtration and glomerular filtration rate. Although available data are limited in particular in cases with more advanced stages of renal failure, bariatric surgery associates with improved filtration and lower proteinuria in patients with mild to moderate renal insufficiency. In patients with more advanced stages of renal failure, surgery should be considered if obesity represents a relative contraindication to transplantation. Surgery seems to improve graft survival. Further, nephrologists should be informed on the metabolic and nutritional changes associated with bariatric surgery, which could be responsible for untoward effects requiring early identification and treatment. Bariatric surgery could be a valid therapeutic option in renal patients to improve the negative clinical outcomes of obese subjects.

Bleeding and gastric fistula are the most common postoperative complications after laparoscopic sleeve gastrectomy (LSG). The long stapler line represents the most frequent source of bleeding, which ranges between 0 and 20%. The aim of this retrospective study was to analyze the 4-year experience of a high-volume center with respect to the prevention and management of perioperative LSG bleeding.The prospectively maintained database from June 2012 to June 2016 was reviewed. Outcomes, especially perioperative bleeding (until patient discharge), its management, and follow-ups, were analyzed.Out of 870 LSG (603 females, 267 males), 31 cases (3.5%) of postoperative complications were registered: bleeding was the most frequent complication (1.9%). Hemoperitoneum was managed laparoscopically in 9/17 patients (52.9%) with only one conversion to laparotomy (11.1%). Conservative treatment successfully controlled bleeding in 8/17 patients (47.1%). However, four patients (50%) developed an infected hematoma; two of them were treated conservatively with a CT-guided drainage, and the other two were complicated by late gastric leak treated laparoscopically. No mortalities occurred in the investigated cases.In a high-volume center, the expected incidence of bleeding after LSG is 1.7% even after the adoption of all preventive strategies. The intraoperative protocol for detecting silent bleeding was effective, and no cases of bleeding were observed since its application. Our findings showed that the conservative management of postoperative bleeding should be considered as a high-risk condition for late leakage.

Background Laparoscopic sleeve gastrectomy (SG) was originally used as a bridge to definitive surgery in high-risk patients. Recently it has been considered as a stand-alone procedure due to its effectiveness on weight loss and comorbidities resolution. This study was designed to evaluate the results of SG on complications, body mass index (BMI), and comorbidities resolution in 300 consecutive obese patients and to analyze the lesson learned from this experience. Methods From October 2002 to November 2009, 300 patients underwent SG. In the first 100 cases (group 1: mean BMI, 54.4 ± 9.3), SG was intended as a first stage of biliopancreatic diversion with duodenal switch in high risk super-obese patients. In the last 200 cases (group 2: mean BMI, 45.5 ± 7.3), SG was intended as a definitive procedure. No routine reinforcement was performed in group 1. In group 2, oversewn reinforcement was performed routinely. SG was redo surgery in 21 patients (7%). Results Mean operative time was 119 ± 48.6 min in group 1 and 72 ± 33.8 in group 2. Conversion rate was 0.6% (massive hepatomegaly). Mortality was 0.6%. Major postoperative complications were registered in 15 patients in group 1 and 11 in group 2. In 3 cases, a reoperation was needed. The mean BMI in group 1 was 46, 43, 39, and 31 at 6, 12, 24, and 36 months, respectively. In group 2, the mean BMI was 32.9, 30.6, and 31.7 at 6, 12, and 18 months. At 12 months, the diabetes, hypertension, and OSAS were cured on 69%, 62%, and 50% in group 1 and 88%, 57%, and 58% in group 2. In group 2, no patient required second stage. Conclusions SG is a safe and effective treatment for morbid obesity at mid-term follow-up. SG is effective for comorbidities resolution, especially for the treatment of diabetes. Suture line reinforcement allows a significant reduction of bleeding.

Laparoscopic revisional bariatric surgery (RBS) is increasingly common. A tailored decision-making process is advocated. In this retrospective study, we reviewed the RBS experience of a single center, analyzing perioperative complications to provide insight into management options and midterm outcomes. Records from November 2011 to March 2015 were reviewed from prospectively maintained database. Six hundred eighteen patients underwent laparoscopic bariatric procedures; of these, 81 (13.1 %) underwent RBS. Patients with a minimum follow-up of 6 months (n = 77) were evaluated. Fifty-nine underwent revised laparoscopic sleeve gastrectomy, and 18 underwent revised Roux-en-Y gastric bypass. Indications for RBS were inadequate weight loss or weight regain in 42 cases (54.5 %) and gastroesophageal reflux disease (GERD), procedure-related complications, or technical failure in 35 cases (45.5 %). There were no deaths or conversions to open surgery. After a mean follow-up of 22 months, body mass index (BMI) decreased from 40.9 ± 6.7 to 31.9 ± 4.8 kg/m2, mean % excess weight loss (%EWL) was 58 ± 24.3 %, and 55.3 % of patients had resolution of comorbidities. Eight major complications (10.4 %) occurred: five leaks and three intra-abdominal hematomas. Non-surgical management succeeded in 50 % of complications. This study confirms that RBS is challenging; a complication rate of 10 % is expected. Major surgery can be avoided when devoted endoscopists and radiologists are available. Intensive follow-up after complications allows early diagnosis and treatment of unfavorable sequelae. RBS induced a mean %EWL of 58 % at 2 years and resolution of comorbidities in 50 % of cases. However, the durability of these effects remains questionable.

AIM To evaluate whether obesity represents a risk factor for the onset of ovarian cancer. PATIENTS AND METHODS One hundred and sixty-three patients with a body mass index (BMI) >30 kg/m2 (group 1) and 130 women with a BMI of 13%) was found in 24.5% of group 1 patients, whereas a high ROMA score was identified in 5.3% of group 2 women. During the study, 13 out of 40 group 1 patients with ROMA >13% were deemed eligible for bariatric surgery. After bariatric surgery and decrease of BMI, eight out of these 13 obese women had a ROMA index

Background: Laparoscopic adjustable gastric banding (LAGB) has become the most popular bariatric intervention in Europe. International guidelines recommended age limits for bariatric surgery of 18-60 years. The aim of this study was to evaluate the immediate results in morbidly obese patients >55 years old, treated with LAGB. Methods: Between January 1996 and January 2004, 350 patients underwent LAGB. 24 (6.8%) were >55 years old (Group A), mean age 58.6±3.3 years, mean preoperative BMI 42.3±4.5 kg/m2. A comparative randomized analysis with 24 patients younger than age 55 years was performed (Group B: mean age 41.2±9.6 years, mean BMI 42.1±3.6 kg/m2). Baseline clinical features, operative parameters and postoperative results were evaluated. Results: No perioperative complications were recorded. Conversion rate and mortality were nil. Major postoperative complications occurred in 2 patients (8.3%) from Group A (1 intragastric prosthesis migration, 1 pouch dilatation) and 2 patients (8.3%) from Group B (intragastric migrations). Reoperation was needed in 3 cases, and one erosion (Group B) is on the waiting list for removal. Minor complications: 1 port infection in each group required ambulatory port substitution; 1 intraperitoneal portcatheter disconnection (Group B) was successfully treated laparoscopically. Mean follow-up was 31.7 months (Group A) and 33.0 months (Group B). Mean postoperative BMI at 12 and 24 months was 35.9±4.2 and 33.8±4.9 for Group A, and 33.8±4.6 and 33.2±6.0 for Group B. Conclusion: There have been no significant differences in results between the 2 groups. LAGB has been safe and effective in patients >55 years old.

The study was carried out on type 2 diabetic obese patients who underwent laparoscopic sleeve gastrectomy (LSG). Patients underwent regular glycemic controls throughout 3 years and all patients were defined cured from diabetes according to conventional criteria defined as normalization of fasting glucose levels and glycated hemoglobin in absence of antidiabetic therapy. After 3 years of follow-up, Continuous Glucose Monitoring (CGM) was performed in each patient to better clarify the remission of diabetes. In this study, we found that the diabetes resolution after LSG occurred in 40% of patients; in the other 60%, even if they showed a normal fasting glycemia and A1c, patients spent a lot of time in hyperglycemia. During the oral glucose tolerance test (OGTT), we found that 2 h postload glucose determinations revealed overt diabetes only in a small group of patients and might be insufficient to exclude the diagnosis of diabetes in the other patients who spent a lot of time in hyperglycemia, even if they showed a normal glycemia (

Gastrogastric fistula is one of the complications that can occur after vertical gastroplasty surgery for weight loss. We describe a novel sleeve gastrectomy technique to treat a proximal gastrogastric fistula after vertical gastroplasty.

Up to 30 % of patients who have undergone laparoscopic sleeve gastrectomy require revision surgery for inadequate weight loss, weight regain, and/or the development of severe upper gastrointestinal symptoms. The aim of this retrospective study was to evaluate the safety and efficacy of laparoscopic fundectomy (LF) in cases of a residual fundus/neofundus development regarding GERD symptoms. The study group comprised 19 patients (17 female; mean BMI 35.4 kg/m2) divided into 2 groups. Group A (n = 10) patients with severe GERD and evidence of residual fundus/neofundus, Hiatal hernia with good results in terms of weight loss. Group B (n = 9) patients with severe GERD, a residual fundus/neofundus, inadequate weight loss or weight regain. Fundectomy was indicated when a residual fundus/neofundus was associated with severe GERD symptoms. The presence of a residual fundus/neofundus was assessed by a barium swallow and/or multislice computed tomography. No mortality or intra-operative complications occurred. Five postoperative complications occurred: 2 cases of bleeding, 1 mid-gastric stenosis and 2 leaks (10.5 %). All patients experienced improvements in their GERD symptoms and stopped PPI treatment. Group B exhibited an additional %EWL of 53.4 % at 24 months. LF and cruroplasty is feasible and has good results in terms of GERD symptoms control and additional weight loss. The high rate of postoperative complications observed in this series remains a matter of concern. A re-sleeve procedure might be considered as an alternative to RYGB/DS conversion restricted to selected patients.

To report the results of an open label prospective study on a new technique for laparoscopic hiatal hernia (HH) repair with absorbable mesh fixed with absorbable materials Methods: From January 2011 to May 2013, 43 patients were treated; group A, 20 patients submitted to laparoscopic sleeve gastrectomy (LSG); group B, 13 patients submitted to revisional surgery for the diagnosis of HH and symptomatic GERD post-LSG; and group C, ten patients submitted to 360° fundoplication. All patients underwent cruroplasty reinforced with bio-absorbable mesh fixed with absorbable tacks and/or fibrin glue. Conversion rate, intra-operative complications, operative time (tacks vs tacks plus fibrin glue), perioperative complications, perioperative symptoms and radiological control set the criteria for clinical/surgical evaluation.Conversion and mortality rate was 0%. The mean time for mesh fixation with the tacks vs tacks plus fibrin glue was 6.2 ± 2 vs 7.3 ± 3 min. The remission of GERD symptoms was observed in 39 patients, and we did not observe any cases of mesh-related complications at a mean follow-up of 17.4 months. Recurrence rate was 2.3% (one asymptomatic patient of group B).Reinforcement with absorbable mesh-cancel bio mesh is a safe and effective option for laparoscopic HH repair in normal weight and obese patients.

The choice of the mesh and fixation methods in laparoscopic incisional hernia repair is a crucial issue in preventing complications and recurrence. The authors report a series of 40 consecutive laparoscopic incisional hernia repairs, focusing on the use of lightweight polypropylene mesh and on the way of mesh fixation.Forty laparoscopic incisional hernia repairs performed consecutively in 38 patients (16 males, 22 females) were retrospectively evaluated. Patients were divided into two groups depending on tacks used: Titanium tacks vs absorbable tacks.All patients received totally laparoscopic incisional hernia repair by the use of lightweight polypropylene mesh. No major post-operative complications were reported. Post-operative pain (evaluated by VNS) was higher in Group A (titanium tacks, p0.05). No differences in follow-up as well as in recurrence incidence (one case in both groups,6 months time interval) were reported.Securestrap™ absorbable tacks are safe and effective and easy to use and did not increase the risk of mesh dislocation compared with non-absorbable tacks. The specific design well fits the lightweight polypropylene mesh Physiomesh™. Further evaluations in larger randomized studies are needed to confirm these preliminary data.

Metabolic syndrome is strictly associated with morbid obesity and leads to an increased risk of cardiovascular diseases and related mortality. Bariatric surgery is considered an effective option for the management of these patients. We searched MEDLINE, Current Contents, and the Cochrane Library for papers published on bariatric surgery outcomes in English from 1 January 1990 to 20 July 2012. We reported the effect of gastrointestinal manipulation on metabolic syndrome after bariatric surgery. Bariatric surgery determines an important resolution rate of major obesity-related comorbidities. Roux-en-Y gastric bypass and biliopancreatic diversion appear to be more effective than adjustable gastric banding in terms of weight loss and comorbidities resolution. However, the results obtained in terms of weight loss and resolution of comorbidities after a “new bariatric procedure” (sleeve gastrectomy) encouraged and stimulated the diffusion of this operation.

A female patient, 48-year-old, with morbid obesity (body mass index 42.5 kg/m2) complicated by hypertension, T2DM, and severe Obstructive Sleep Apnea Syndrome was candidated to bariatric surgery. During the preoperative work-up, an abdominal ultrasonography and an RMN showed an incidental left adrenal tumor with a diameter of 11 cm. The laboratory evaluation for the functional adrenal tumor was negative. A laparoscopic sleeve gastrectomy and left adrenalectomy with supragastric approach was successfully carried out. The minimally invasive treatment of coexisting abdominal pathologies such as morbid obesity and adrenal incidentalomas seem to be suitable and safe, providing several benefits in terms of surgical and anesthesiologic management and postoperative clinical outcomes. The supragastric approach may represent a valuable option for left adrenalectomy combined with laparoscopic sleeve gastrectomy.

Background This study aimed to compare the efficacy of laparoscopic sleeve gastrectomy (SG) with that of laparoscopic gastric bypass (GBP) and laparoscopic adjustable gastric banding (AGB) for glucose homeostasis in morbidly obese subjects with type 2 diabetes mellitus (T2DM) at a 3-year follow-up assessment and to elucidate the role of weight loss in the T2DM resolution after SG. Methods For this study, 60 morbidly obese T2DM patients (44 females and 16 males) who underwent AGB (24 patients), GBP (16 patients), or SG (20 patients) between 1996 and 2008 were retrospectively analyzed. Age, sex, body mass index (BMI), estimated weight loss (EWL), fasting glycemia, HbA1c, euglycemic hyperinsulinemic clamp, discontinuation of diabetes treatment, and time until interruption of therapy were evaluated. Results In the study, 54 patients received oral hypoglycemic agents for at least 12 months before surgery, and 6 patients received insulin. The mean follow-up period was 36 months. The resolution rate was 60.8% for the AGB patients, 81.2% for the GBP patients, and 80.9% for the SG patients. The postoperative time until interruption of therapy was 12.6 months for the AGB patients, 3.2 months for the GBP patients, and 3.3 months for the SG patients. The hyperinsulinemic euglycemic clamp test was performed 12 months after surgery for the cured patients. Insulin resistance was restored to normal values in all the patients. The greatest improvement from preoperative values occurred in the SG group. For the not-cured GBP and SG patients, an improvement of 120 mg/dl in fasting plasma glucose was observed 3 months after the surgery, suggesting an enhancement in insulin sensitivity, which determines better medical control. The resolution rate remained constant at the 36-month follow-up evaluation in both the GBP and SG groups. Conclusions All three bariatric procedures are effective in treating diabetes, with a 3-year follow-up evaluation showing an effect that lasts. The AGB procedure was the least effective. The antidiabetic effect was similarly precocious after GBP and SG compared with AGB. This difference may indicate that a hormonal mechanism may be involved, independent of weight loss.

Biliopancreatic diversion and gastric bypass are associated with a rapid improvement in insulin resistance few days after surgery. The purpose of this study was to evaluate the short-term effects in insulin resistance following sleeve gastrectomy (SG).Between December 2007 and September 2008, 17 consecutive obese type 2 diabetes mellitus patients (three men, mean age 51.1 years, mean BMI 44.7 kg/m(2)) were submitted to laparoscopic SG. Fasting serum glucose, insulin concentration, and homeostatic model assessment for insulin resistance (HOMA IR) were drawn preoperatively and at 5, 15, 30, and 60 postoperative days. In seven of these patients insulin sensitivity was evaluated on postoperative days 1, 2, 3, and 4. Moreover a control group of three overweight and diabetic patients (one man, mean age 52.1 years and mean BMI 26.8 kg/m(2)) submitted to laparoscopic cholecystectomy and undergoing the same diet protocol was studied.In all obese patients, a sharp (5 days) and significant reduction of serum glucose and insulin concentration and HOMA IR values was observed after SG. In seven patients, serum glucose and insulin concentration and HOMA IR values were significantly lower at third postoperative day. At the 15th postoperative day both serum glucose and insulin concentration and HOMA IR remained significantly lower in the absence of significant weight modifications. At 30 and 60 postoperative days, these values remained substantially unchanged in spite of a greater weight loss. In the cholecystectomy patients group, at postoperative day 5, only the serum glucose concentrations were significantly reduced although with the higher values than normal in respect to the preoperative values.After SG the improvement of insulin action occurred rapidly and independently of EWL. The results of the present study confirm that a hormonal mechanism may contribute to changes in insulin resistance following SG.

The prevalence of gastroesophageal reflux disease (GERD) and/or hiatal hernia (HH) is significantly increased in morbidly obese patients. Laparoscopic bariatric procedures such as gastric banding (LGB) and Roux-en-Y gastric bypass have been shown to improve both obesity and reflux symptoms. The aim of this paper is to evaluate the effectiveness of laparoscopic sleeve gastrectomy (LSG) and hiatal hernia repair (HHR) for the treatment of obesity complicated by HH.From October 2008, six patients underwent HHR in addition to LSG. Clinical outcomes have been evaluated in terms of GERD symptoms improvement or resolution, interruption of antireflux medication, and X-ray evidence of HH recurrence.Symptomatic HH was diagnosed preoperatively in four patients. In two additional patients, HH was asymptomatic and it was diagnosed intraoperatively. Prosthetic reinforcement of crural closure was performed in two symptomatic cases with a HH5 cm. Mortality was nil and no complications occurred. After a mean follow-up of 4 months, GERD symptoms resolution occurred in three patients, while the other patient reported an improvement of reflux. Body mass index had fallen from 43.4 to 36.2 kg/m(2). A small recurrence in the patient with persistence of reflux symptoms has been radiologically reported.Laparoscopic crural closure in addition to LSG could represent a valuable option for the synchronous management of morbid obesity and HH, providing good outcomes in terms of weight loss and GERD symptoms control.

Laparoscopic sleeve gastrectomy (LSG) is gaining popularity as a "per se" bariatric procedure due to its effectiveness on weight loss and comorbidity resolution. The most feared and life-threatening complication after LSG is the staple line leak and its management is still a debated issue. Aim of this paper is to analyze the incidence of leak and the treatment solutions adopted in a consecutive series of 200 LSG.From October 2002 to November 2008, 200 patients underwent LSG. Nineteen patients (9.5%) had a body mass index (BMI) of60 kg/m(2). A 48-Fr bougie is used to obtain an 80-120-ml gastric pouch. An oversewing running suture to reinforce the staple line was performed in the last 100 cases. The technique adopted to reinforce the staple line is a running suture taken through and through the complete stomach wall.Staple line leaks occurred in six patients (mean BMI 52.5; mean age 41.6 years). Leak presentation was early in three cases (first, second, and third postoperative (PO) day), late in the remaining three cases (11th, 22nd, and 30th PO day). The most common leak location was at the esophagogastric junction (five cases). Mortality was nihil. Nonoperative management (total parenteral nutrition, proton pump inhibitor, and antibiotics) was adopted in all cases. Percutaneous abdominal drainage was placed in five patients. In one case, a small fistula was successfully treated by endoscopic injection of fibrin glue only. Self-expandable covered stent was used in three cases. Complete healing of leaks was obtained in all patients (mean healing time 71 days).Nonoperative treatment (percutaneous drainage, endoscopy, stent) is feasible, safe, and effective for staple line leaks in patients undergoing LSG; furthermore, it may avoid more mutilating procedures such as total gastrectomy.

The aim of this study is to retrospectively analyze the incidence of complications after two-stage laparoscopic biliopancreatic diversion with duodenal switch (Lap BPD-DS) in high-risk super-obese patients and explore the possible predictive factors of specific complications after laparoscopic sleeve gastrectomy (SG).High-risk patients--body mass index (BMI)50 kg/m(2) with at least two major comorbidities: type 2 diabetes, obstructive sleep apnea syndrome (OSAS), hypertension--undergoing two-stage laparoscopic BPD-DS were retrospectively analysed. The SG pouch volume was 100-150 ml; in the second stage, the common channel and the alimentary loop were 100 cm and 150 cm, respectively.Eighty-seven patients (50 female, 57.5%) underwent SG (two open). The mean age was 41.8 +/- 10.22 years with BMI of 55.2 +/- 6.69 kg/m(2). Four patients had Prader-Willy syndrome. Fourteen (16.46%) patients (6 female, 42.8%) had postoperative complications such as bleeding, fistula, pulmonary embolism, transitory acute renal failure, and abdominal abscess. One patient died at postoperative day 5 of pulmonary embolism. One patient was reoperated for hemoperitoneum by laparoscopy. The risk of complications after SG was lower in patients where reinforcement of the suture line was used (0.492), while it was higher in men (1.780). Neither difference was statistically significant [p = not significant (NS)]. After 9-24 months, 27 patients (BMI 43 +/- 8 kg/m(2)) underwent a second stage of BPD-DS (two open). Major postoperative complications were registered in eight patients (29.6%): three bleeding, four duodeno-ileal stenosis and one rhabdomyolysis. Two cases of internal hernia required laparoscopic reoperation. The reoperation rate was 1/85 (1.2%) after SG and 2/27 (7.4%) after second stage.Complications after SG greatly decrease after the learning curve period and can be successfully managed without need of reoperation. Suture-line reinforcement, at least selectively in the middle-upper portion of the staple line and in super-super-obese patients, is recommended to decrease the incidence of specific complications.

Background To assess the rates and causes of reoperations in a long-term follow-up of a cohort of morbidly obese patients treated by laparoscopic adjustable gastric banding. Methods A retrospective study was performed to evaluate a cohort of 498 consecutive patients who had undergone laparoscopic adjustable gastric banding since 1996. The first 50 patients were excluded to avoid the learning curve bias. A perigastric technique was used until 2002 (37% of patients) and was then rapidly replaced by a pars flaccida approach. The patients who underwent band removal or port reposition/removal were considered, respectively, as having required a major or minor reoperation. Results Of the 448 patients (83% women) followed up for an average of 3.2 ± 2.2 years, 79 (mean age 37.7 years, mean body mass index 44.0 kg/m 2 ) underwent repeat surgery between 1997 and 2006. Of these procedures, 29 were minor and 59 were major reoperations. Ten patients underwent band removal after a port complication developed. The main causes were pouch dilation (37%), insufficient weight loss (20%), erosion (20%), and psychological (15%). Ten patients underwent revisional surgery. A 13% incidence of major reoperations was observed for the entire group; the rate of major and minor reoperations was 4.1 and 2.1 interventions per 100 persons-years, respectively. In patients with follow-up >5 years (perigastric technique), the cumulative incidence reached 24%. Conclusion The need for a major reoperation appears to be substantial in patients who have undergone laparoscopic adjustable gastric banding, particularly when the long-term follow-up data are considered, and can occur at any point after surgery. More severe obesity (body mass index >50 kg/m 2 ) seems to carry a greater risk of reoperation. These findings highlight the need for lifelong multidisciplinary management and surveillance for these patients.

Background: We evaluated laparoscopic sleeve gastrectomy (LSG) on major co-morbidities (hypertension, type 2 diabetes / impaired glucose tolerance, obstructive sleep apnea syndrome (OSAS) and on American Society of Anesthesiologists (ASA) operative risk score in high-risk super-obese patients undergoing two-stage laparoscopic biliopancreatic diversion with duodenal switch (LBPD-DS). Methods: 41 super-obese high-risk patients (mean BMI 57.3±6.5 kg/m2, age 44.6±9.7 years) were entered into a prospective study (BMI ≥60, or BMI ≥50 with at least two severe co-morbidities, no Prader-Willi syndrome, no conversion, minimum follow-up 12 months). 9 patients had BMI ≥60. 17 patients (41.4%) had OSAS on C-PAP therapy. In 10 patients, at least one intragastric balloon had been positioned and 4 had undergone laparoscopic adjustable gastric banding, all with unsatisfactory results. At surgery, 41.5% were classified ASA 4 and 58.5% as ASA 3 (mean ASA score 3.4±0.5). Patients underwent evaluation every 3 months postoperatively and were restaged at 12 months and/or before the second step. Results: 60% of major co-morbidities were cured and 24% improved. Average BMI after 6 and 12 months was 44.5±8.1 and 40.8±8.5 respectively (mean follow-up 22.2±7.1 months). After 12 months, 57.8% of the patients were co-morbidity-free and 31.5% had only one major co-morbid condition. At restaging, 20% of patients were still classified as ASA score 4 (OSAS on C-PAP therapy). 3 patients showed BMI

Background: An association between obesity and cancer has been shown in large epidemiological studies. The aim of this study was to evaluate the prevalence and types of malignancies in an Italian cohort of obese patients referred to a bariatric center. Methods: A retrospective, observational study was conducted. Between Jan 1996 and Dec 2004, 1,333 obese patients (M=369, F=964) were seen in the center for minimally invasive treatment of morbid obesity. Morbid obesity were considered as BMI >40 kg/m2 or BMI >35 kg/m2 with at least one co-morbidity. Obese and morbidly obese patients who suffered any form of cancer were reviewed. Results: 43 patients (3.2%) presented various malignancies, with 88.3% in females. The prevalence of cancer in the younger group (21-46 years) was higher than in the older group (47-70 years), 2.1% vs 1.1%. 26 obese patients out of the 43 (60.5%) (age 41±7.9 years, BMI 38.2±9.9) presented hormone-related tumors. The most frequent site of cancer was breast (20.9%), followed closely by thyroid. Conclusion: This is the first Italian report on prevalence of cancer in a homogeneous obese population attending an academic bariatric center. The morbidly obese patients appear to have a higher risk of developing cancer, with a higher prevalence of hormone-related tumors. The predominant gender affected by both obesity and cancer was female. Thus, a preoperative work-up for cancer screening is indicated in this group of patients.

Hypothesis Complications after laparoscopic adjustable gastric banding as treatment for morbid obesity may require a major reintervention. A minimally invasive approach represents an attractive management alternative for such complications. Design Prospective case series. Setting Major academic medical and surgical center. Patients From January 1996 to July 2003, 47 patients who had undergone laparoscopic adjustable gastric banding were operated on again. Considering the causes for reoperation, the patients were divided into 4 groups: group A had major complications (n = 26); group B, minor complications (n = 11); group C, psychological problems (n = 6); and group D, insufficient weight loss (n = 4). Interventions Forty-three procedures, 38 using general anesthesia (groups A, C, and D) and 5 using local anesthesia (group B), were performed. Main Outcome Measures Feasibility, safety, and effectiveness of a minimally invasive approach in the treatment of laparoscopic adjustable gastric banding complications. Results In group A, 9 of 10 patients with irreversible gastric pouch dilatation and 15 of 16 with intragastric band migrations were treated laparoscopically. In group B, 5 ports were substituted and 2 reconnections of the catheter-port system were performed. In group C, 6 laparoscopic band removals were carried out. In group D, 4 laparoscopic revision procedures for insufficient weight loss were performed. The operative mortality was nil. The most frequent cause of reoperation was intragastric migration (37.2%). A minimally invasive approach was adopted in 94.7% of cases. Conclusion Laparoscopy is safe and effective, even as a second operative procedure.

Background Radical cystectomy with pelvic lymph node dissection represents the standard treatment for muscle-invasive, and high-risk non-muscle-invasive bladder cancers. Aim of this study was to report our case series of 30 patients undergoing totally laparoscopic radical cystectomy (LRC) with reconstruction of an intracorporeal orthotopic ileal neobladder. Intra- and perioperative results and the functional and oncological outcomes 9 months after operation are reported. Methods Between October 2010 and December 2012, 30 male patients underwent LRC with a pure laparoscopic orthotopic ileal “U”- shaped neobladder diversion. The men had a median age of 67 years, a median body mass index of 22.3, and a mean ASA score of 2.2; they represented various clinical stages of disease. Results None of the patients required conversion to open surgery, and no perioperative mortalities were reported. The median operating time was 365 min, and the median blood loss was 290 mL, with a transfusion rate of 26.6%. All surgical margins were negative; 8 patients with non–organ-confined disease or positive lymph nodes received adjuvant chemotherapy. Early complications (within 30 days) occurred in 7 patients, and late complications occurred in 6 patients. The mean hospital stay was 9 days. At 9 months after surgery, the daytime continence rate was 83.3% and the nighttime continence rate was 73.3%. Conclusions Pure LRC with intracorporeal orthotopic ileal neobladder reconstruction may represent a viable alternative to open radical cystectomy, with a significant reduction in patient morbidity. Future, large, randomized controlled trials with extensive follow-up are needed to confirm our encouraging results.
