Visceral adipose tissue adiponectin predicts excess weight loss after bariatric surgery in females with severe obesity.

OBJECTIVE: Bariatric surgery not always results in satisfactory excess weight loss (EWL) in severe obesity. Given the economic and clinical costs of bariatric surgery failure, defining predictors of successful EWL represents a relevant clinical issue for the health system to select patients benefiting from operation. METHODS: By ELISA and Western blot analyses, we assessed the predicting value of pre-operative adiponectin (APN) locally produced in abdominal visceral (VAT) and subcutaneous (SAT) adipose tissue versus plasma levels as a novel sex-linked biomarker of EWL at different time points of follow up (6-24 months) after bariatric surgery in 43 patients (56% females) affected by severe obesity undergoing a small pilot observational study. RESULTS: VAT-APN was lower in females and represented the only marker significantly correlated with EWL. In females, VAT-APN in the distribution upper quartile but not baseline BMI retained a statistically significant correlation with EWL at any time points (6-24 months) at multivariate analysis. The best VAT-APN cut-off value to predict 95% EWL at 12 months from surgery (98% accuracy, 100% sensitivity, 94% specificity, p = 0.010) was 5.1 µg/mg. CONCLUSIONS: In this very preliminary study, APN in VAT rather than its circulating or subcutaneous levels predicts EWL after bariatric surgery as an independent factor in the female sex only, thus contributing to identify those patients who could much benefit from surgery.

SICOB-endorsed national Delphi consensus on obesity treatment optimization: focus on diagnosis, pre-operative management, and weight regain/insufficient weight loss approach.

PURPOSE: Overweight and obesity affects 60% of adults causing more than 1.2 million deaths across world every year. Fight against involved different specialist figures and multiple are the approved weapons. Aim of the present survey endorsed by the Italian Society of Bariatric Surgery (SICOB) is to reach a national consensus on obesity treatment optimization through a Delphi process. METHODS: Eleven key opinion leaders (KOLs) identified 22 statements with a major need of clarification and debate. The explored pathways were: (1) Management of patient candidate to bariatric/metabolic surgery (BMS); (2) Management of patient not eligible for BMS; (3) Management of patient with short-term (2 years) weight regain (WR) or insufficient weight loss (IWL); (4) Management of the patient with medium-term (5 years) WR; and (5) Association between drugs and BMS as WR prevention. The questionnaire was distributed to 65 national experts via an online platform with anonymized results. RESULTS: 54 out of 65 invited panelists (83%) respond. Positive consensus was reached for 18/22 statements (82%); while, negative consensus (s20.4; s21.5) and no consensus (s11.5, s17) were reached for 2 statements, respectively (9%). CONCLUSION: The Delphi results underline the importance of first-line interdisciplinary management, with large pre-treatment examination, and establish a common opinion on how to properly manage post-operative IWL/WR.

GORD and Barrett's oesophagus after bariatric procedures: multicentre prospective study.

INTRODUCTION: Gastro-oesophageal reflux disease (GORD) after bariatric surgery is a debated topic. This study investigated the prevalence of GORD and associated oesophageal complications following bariatric procedures-namely, adjustable gastric banding (AGB), sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), and one-anastomosis gastric bypass (OAGB). METHODS: This was a prospective multicentre study designed to evaluate the long-term effects of bariatric surgery on GORD. Patients were studied at baseline, at >10 years following AGB, SG, and RYGB, and at >3 years following OAGB (due to the more recent recognition of OAGB as a standard bariatric procedure). Patients were assessed by endoscopy and GORD symptom evaluation. RESULTS: A total of 241 patients were enrolled. A minimum follow-up of 10 years was completed by 193 patients following AGB (57 patients), SG (95 patients), and RYGB (41 patients), and of >3 years by 48 subjects following OAGB. GORD symptoms increased following AGB and SG (from 14 to 31.6 per cent and from 26.3 to 58.9 per cent, respectively; P < 0.0001), improved following RYGB (from 36.6 to 14.6 per cent; P < 0.0001), and were unchanged following OAGB. The overall prevalence of erosive oesophagitis was greater in the SG group (74.7 per cent) than in the AGB (42.1 per cent), RYGB (22 per cent), and OAGB (22.9 per cent) groups (P < 0.0001). Barrett's oesophagus was found only in patients who had SG (16.8 per cent). Biliary-like gastric stagnation was found in a greater proportion of SG and OAGB patients (79.7 and 69.4 per cent, respectively) than in other treatment groups (P < 0.0001). The prevalence of biliary-type reflux into the oesophagus was higher in patients who underwent SG (74.7 per cent), compared with other treatment groups. CONCLUSION: Bariatric surgery leads to gastro-oesophageal complications of variable severity, particularly SG, which can result in a large proportion of patients developing Barrett's oesophagus.

Gastro-oesophageal reflux disease (GORD)-related oesophageal sequelae following bariatric surgery confirm the importance of postoperative endoscopic surveillance in early detection of such conditions. Sleeve gastrectomy was shown to be correlated with the highest prevalence of GORD, biliary-type gastric and oesophageal reflux, and erosive oesophagitis. This, in turn, appeared to be responsible for the high number of cases of Barrett's oesophagus found in this group of patients. Adjustable gastric banding displayed minimal effectiveness in terms of weight loss, along with a high number of reoperations, also due to band-related complications. The study showed one-anastomosis gastric bypass to be associated with a high percentage of subjects who developed often severe inflammation of the gastrojejunal anastomosis or of the gastric pouch, as a consequence of chronic biliary-type duodenogastric reflux. Finally, our results suggest that Roux-en-Y gastric bypass could represent the most 'reliable' bariatric procedure in terms of GORD resolution, and the only operation not requiring any reintervention in our cohort of patients. Each surgical procedure leads to gastro-oesophageal modifications of variable extent, which need to be taken into consideration when selecting the designated bariatric operation.

Preliminary results of the influence of the in vivo use of a lymphatic dye (patent blue v) in the surgical treatment of Crohn's disease.

INTRODUCTION: Recently, the lymphatic vessels has been considered to play a key role in the pathophysiology and, consequently, in the treatment of Crohn's disease (CD). The aim of this study is to show that the evaluation of lymphatic anomaly might be a useful tool in the recognition of the pathological involvement of the intestinal wall in CD. MATERIAL AND METHODS: Fourteen patients with CD who underwent surgical treatment for distal ileum critical stenosis were prospectively evaluated. During surgery, 0.05 to 0.1 mL of Patent Blue V was injected into the subserosal layer of the antimesenteric edge of ileum and colon. The intestinal section was performed just beneath the outflow of the vital dye where it seemed to be normal (≤2 minutes), as a index of healthy intestinal wall. A comparison between the lymphatic alterations and the macroscopic aspects was performed. RESULTS: Out of 14 patients, 13 were electively operated on, whereas 1 was treated in emergency. In 8 patients (57%), laparoscopic approach was chosen in the first instance. One patient needed laparotomic conversion. When comparing the Patent Blue V outflow time with the macroscopic and microscopic evidence of CD, we found an absolute integrity of the intestinal wall with an outflow ≤2 minutes. Mean follow-up was 110 months with a recurrence rate of 14%. CONCLUSION: We can conclude that this method may be of utility to distinguish between normal and diseased intestine in CD. The possible consequences in postsurgical recurrences of this evidence are critical.

Psychological effects and outcome predictors of three bariatric surgery interventions: a 1-year follow-up study.

PURPOSE: Weight loss surgery efficacy has been demonstrated for morbid obesity. Different outcomes have been hypothesized, according to specific bariatric surgery interventions and psychological characteristics of obese patients. The present study compared three different surgery procedures, namely laparoscopic adjustable gastric band (LAGB), Roux-en-Y gastric bypass (RYGB) and biliopancreatic diversion (BPD), in terms of weight loss efficacy and psychological outcomes. METHODS: Eighty-three subjects seeking bariatric surgery have been evaluated before and 12 months after surgery intervention, by means of a clinical interview and different self-reported questionnaires, including Eating Disorder Examination Questionnaire, Emotional Eating Scale, Binge Eating Scale, Beck Depression Inventory, Symptom Checklist and State-Trait Anxiety Inventory. RESULTS: BPD group (26 subjects) showed the greatest weight loss, followed by RYGB (30 subjects), and LAGB group (27 subjects). All the treatments were associated with a significant improvement of anxiety, depression, and general psychopathology, and a similar pattern of reduction of binge eating symptomatology. BPD group reported a greater reduction of eating disorder psychopathology, compared to the other groups. Pre-treatment emotional eating severity was found to be a significant outcome modifier for the three treatment interventions. CONCLUSIONS: These results suggest that all the three types of bariatric surgery significantly improved psychopathology and eating disordered behaviors. They also support the importance of a pre-treatment careful psychological assessment in order to supervise the post-surgical outcome.

Psychopathological similarities and differences between obese patients seeking surgical and non-surgical overweight treatments.

PURPOSE: To compare the psychopathological characteristics of obese patients seeking bariatric surgery with those seeking a medical approach. METHODS: A total of 394 consecutive outpatients seeking bariatric surgery were compared with 683 outpatients seeking a medical treatment. All patients were referred to the same institution. RESULTS: Obesity surgery patients reported higher body mass index (BMI), objective/subjective binging and more severe general psychopathology, while obesity medical patients showed more eating and body shape concerns. Depression was associated with higher BMI among obesity surgery clinic patients, whereas eating-specific psychopathology was associated with higher BMI and objective binge-eating frequency among obesity medical clinic patients. CONCLUSIONS: Patients seeking bariatric surgery showed different psychopathological features compared with those seeking a non-surgical approach. This suggests the importance for clinicians to consider that patients could seek bariatric surgery on the basis of the severity of the psychological distress associated with their morbid obesity, rather than criteria only based on clinical indication.

Intragastric gastric band migration: erosion: an analysis of multicenter experience on 177 patients.

BACKGROUND: Laparoscopic adjustable gastric banding (LAGB) has proven to be a safe and effective surgical treatment for morbid obesity. It can be a simple, fast, reversible, anatomy-preserving procedure. Despite these advantages, its long-term efficacy came into question by the occurrence of complications such as intragastric band migration. Consistent information regarding this complication is still lacking. Treatment for migration is still being debated as well. Most of the inconsistencies of these data stem from the very low number of patients reported in single-center experiences or case reports. Lack of multicenter experience is evident. The aim of this study was to perform a retrospective analysis of data on intragastric migration in a large multicenter cohort of patients who underwent LAGB. METHODS: A retrospective multicenter study on LAGB patients was performed. Data had been entered into a prospective database of the Italian Group for LapBand(®) (GILB) since January 1997. Pars flaccida and perigastric positioning were considered along with different kinds of gastric bands by the same manufacturer. Time of diagnosis, mean body mass index (BMI), presentation symptoms, and conservative and surgical therapy of intragastric migration were considered. RESULTS: From January 1997 to December 2009, a total of 6,839 patients underwent LAGB and their data were recorded [5,660 females, 1,179 males; mean age 38.5 ± 18.2 years (range 21-62 years); mean BMI = 46.7 ± 7.7 kg/m(2) (range 37.3-68.3); excess weight (EW) 61.8 ± 25.4 kg (range 36-130); %EW 91.1 ± 32.4 % (range 21-112 %)]. A total of 177 of 6,839 (2.5 %) intragastric erosions were observed. According to the postoperative time of follow-up, the diagnosis of intragastric migration was made in 74 (41.8 %), 14 (7.9 %), 38 (21.4 %), 40 (22.6 %), 6 (3.4 %), and 4 (2.2 %) banded patients at 6-12, 24, 36, 48, 60, and 72 months after banding, respectively. Most of intragastric band migration during the first 2 years occurred in bands with no or a few milliliters of filling. In patients with late erosion, the bands were adjusted several times; no band was overfilled but one was filled to the maximum or submaximum with a maximum of two adjustments. Erosions diagnosed during the first 24 months were related to the experience of the surgical staff, while late erosions were not. CONCLUSIONS: Intragastric band migration or band erosion is a rare, disturbing, and usually not life-threatening complication of gastric banding. Its pathogenesis is probably linked to different mechanisms in early (technical failure in retrogastric passage) or late (band management) presentation. It is usually asymptomatic and there is no pathognomonic presentation. A wide range of therapeutic options are available, from simple endoscopic or laparoscopic removal to early or late band replacement or other bariatric procedure. More experience and more studies are needed to lower its presentation rate and definitively clarify its pathogenesis to address the right therapeutic option.

Bariatric Surgery for Patients with Overweight/Obesity. A Comprehensive Grading Methodology and Network Metanalysis of Randomized Controlled Trials on Weight Loss Outcomes and Adverse Events.

This study aims to compare different types of metabolic bariatric surgery (MBS) with lifestyle intervention/medical therapy (LSI/MT) for the treatment of overweight/obesity. The present and network meta-analysis (NMA) includes randomized trials. MBS was associated with a reduction of BMI, body weight, and percent weight loss, when compared to LSI/MT, and also with a significant reduction of HbA1c and a higher remission of diabetes. Meta-regression analyses revealed that BMI, a higher proportion of women, and a longer duration of trial were associated with greater effects of MBS. The NMA showed that all surgical procedures included (except greater curvature plication) were associated with a reduction of BMI. MBS is an effective option for the treatment of obesity. The choice of BMI thresholds for eligibility for surgery of patients with different complications should be performed making an evaluation of risks and benefits in each BMI category.

Revisional Surgery After One Anastomosis/Minigastric Bypass: an Italian Multi-institutional Survey.

BACKGROUND: Efficacy and safety of OAGB/MGB (one anastomosis/mini gastric bypass) have been well documented both as primary and as revisional procedures. However, even after OAGB/MGB, revisional surgery is unavoidable in patients with surgical complications or insufficient weight loss. METHODS: A questionnaire asking for the total number and demographics of primary and revisional OAGB/MGBs performed between January 2006 and July 2020 was e-mailed to all S.I.C. OB centres of excellence (annual caseload > 100; 5-year follow-up > 50%). Each bariatric centre was asked to provide gender, age, preoperative body mass index (BMI) and obesity-related comorbidities, previous history of abdominal or bariatric surgery, indication for surgical revision of OAGB/MGB, type of revisional procedure, pre- and post-revisional BMI, peri- and post-operative complications, last follow-up (FU). RESULTS: Twenty-three bariatric centres (54.8%) responded to our survey reporting a total number of 8676 primary OAGB/MGBS and a follow-up of 62.42 ± 52.22 months. A total of 181 (2.08%) patients underwent revisional surgery: 82 (0.94%) were suffering from intractable DGER (duodeno-gastric-esophageal reflux), 42 (0.48%) were reoperated for weight regain, 16 (0.18%) had excessive weight loss and malnutrition, 12 (0.13%) had a marginal ulcer perforation, 10 (0.11%) had a gastro-gastric fistula, 20 (0.23%) had other causes of revision. Roux-en-Y gastric bypass (RYGB) was the most performed revisional procedure (109; 54%), followed by bilio-pancreatic limb elongation (19; 9.4%) and normal anatomy restoration (19; 9.4%). CONCLUSIONS: Our findings demonstrate that there is acceptable revisional rate after OAGB/MGB and conversion to RYGB represents the most frequent choice.

A rare case of epidermoid cyst of the cecum.

Epidermoid cysts of the gastrointestinal tract are very uncommon and the published literature on this subject is anecdotal. We report the case of a 51-year-old man who was diagnosed with a cystic neoplasm located close to the cecum and the appendix. Given the strong suspicion of an appendiceal mucocele, the patient underwent a laparoscopic exploration. During the operation, a semisolid mass appearing to originate from the cecal wall was identified and a laparoscopic ileo-cecal resection was performed. The pathological diagnosis was an epidermoid cyst of the cecum. An epidermoid cyst of the cecum is a rare entity that usually has a mild and aspecific clinical picture. However, it should be included in the differential diagnosis of an occasionally diagnosed peri-cecal cystic lesion.

Small Bowel Obstruction After Laparoscopic Roux-en-Y Gastric Bypass Caused by Hemobezoar: A Case Series and Review of Literature.

BACKGROUND: The development of an intraluminal blood clot (hemobezoar), represents a rare cause (0.05% to 1.9%) of small bowel obstruction (SBO) after laparoscopic Roux-en-Y gastric bypass (LRYGB). We present a case series of 6 cases of SBO caused by hemobezoar. METHODS: A retrospective analysis of a prospective database including patients who underwent LRYGB from January 2010 to December 2019 has been performed. All the patients who underwent reoperation because of an SBO caused by an intraluminal blood clot were included in the present study. RESULTS: Six of 843 LRYGB patients developed an hemobezoar (0.71%). Primary LRYGB was uneventful in all cases. SBO symptoms developed after a mean interval of 26.6 hours from the primary procedure. All reoperations were performed with the laparoscopic approach. In all cases, the hemobezoar was located at the level of the jejunojejunal anastomosis (JJA) and was removed through an enterotomy performed at the distal end of the biliopancreatic stump. Three postoperative complications occurred: 1 ab-ingestis pneumonia, 1 leak of the JJA requiring further reoperation, and 1 pelvic abscess treated with radiologic drainage. The mean hospital stay was 11 days. DISCUSSION: SBO due to hemobezoar is a rare but worrisome early complication after LRYGB. It almost always affects the JJA and requires a prompt diagnosis to avoid dreadful sequelae. In the absence of anastomotic leak or stenosis, surgical management may consist of the removal of the blood clot without refashioning the anastomosis and it may be accomplished with the laparoscopic approach.

Laparoscopic adjustable gastric banding via pars flaccida versus perigastric positioning: technique, complications, and results in 2,549 patients.

AIM: Retrospective multicenter analysis of the results of two different approaches for band positioning: perigastric and pars flaccida. METHODS: Data were collected from the database of the Italian Group for LapBand (GILB). Patients operated from January 2001 to December 2004 were selected according to criteria of case-control studies to compare two different band positioning techniques: perigastric (PG group) and pars flaccida (PF group). Demographics, laparotomic conversion, postoperative complications, and weight loss parameters were considered. Data are expressed as mean +/- standard deviation. RESULTS: 2,549 patients underwent the LapBand System procedure [age: 40 +/- 11.7 years; sex: 2,130 female, 419 male; body mass index (BMI): 46.4 +/- 6.9 kg/m(2); excess weight (EW): 60.1 +/- 23.6 kg; %EW: 90.1 +/- 32.4]. During this period 1,343/2,549 (52.7%) were operated via the pars flaccida (PF group) and 1,206/2,549 (47.3%) via the perigastric approach (PG group). Demographics for both groups were similar. Thirty-day mortality was absent in both groups. Operative time was significantly longer in the PG group (80 +/- 20 min versus 60 +/- 40 min; p < 0.05). Hospital stay was similar in the two groups (2 +/- 2 days). Laparotomic conversion was significantly higher in the PG group (6 versus 2 patients; p < 0.001). Overall postoperative complication rate was 172/2,549 (6.7%) and was linked to gastric pouch dilation/slippage (67/172), intragastric migration/erosion (17/172), and tube/port failure (88/172). Gastric pouch dilation and intragastric migration were significantly more frequent in the PG group: 47 versus 20 (p < 0.001) and 12 versus 5 (p < 0.001), respectively. Patients eligible for minimum 3-year follow-up were 1,118/1,206 (PG group) and 1,079/1,343 (PF group). Mean BMI was 33.8 +/- 12.1 kg/m(2) (PG group) and 32.4 +/- 11.7 kg/m(2) (PF group) (p = ns), and mean percentage excess weight loss (%EWL) was 47.2 +/- 25.4 and 48.9 +/- 13.2 in PG and PF groups, respectively (p = ns). CONCLUSIONS: Significant improvement in LapBand System results with regard to laparotomic conversion and postoperative complication rate, with similar weight loss results, was observed in the pars flaccida group.

Laparoscopic Management of Internal Hernia After One Anastomosis Gastric Bypass (OAGB).

Among the advantages of the One Anastomosis Gastric Bypass (OAGB) are the lack of jejuno-jejunal anastomosis and a supposed lower incidence of internal hernia (IH), with only a few cases reported until now. However, the incidence of IH after OAGB is not null. We present a video of the laparoscopic management of an IH that occurred after an OAGB. The patient was a 49-year-old female who had undergone a laparoscopic revisional OAGB 2 years previously after a failed laparoscopic adjustable gastric banding. She was referred to our Unit for recurrent postprandial colicky pain. She lost a total of 50 kg and her body mass index (BMI) dropped from 38 to 19 kg/m2. A CT scan with intravenous contrast showed a swirl of the mesentery around the superior mesenteric artery, without small bowel obstruction. A laparoscopic exploration was performed, confirming the suspicion of IH at the Petersen's space. An anticlockwise derotation of the whole common limb was performed, and the Petersen's space was eventually closed with a running non-absorbable suture.

Seminal but not Serum Levels of Holotranscobalamin are Altered in Morbid Obesity and Correlate with Semen Quality: A Pilot Single Centre Study.

Vitamin B12 (cobalamin) is an essential cofactor in the one-carbon metabolism. One-carbon metabolism is a set of complex biochemical reactions, through which methyl groups are utilised or generated, and thus plays a vital role to many cellular functions in humans. Low levels of cobalamin have been associated to metabolic/reproductive pathologies. However, cobalamin status has never been investigated in morbid obesity in relation with the reduced semen quality. We analysed the cross-sectional data of 47-morbidly-obese and 21 lean men at Careggi University Hospital and evaluated total cobalamin (CBL) and holotranscobalamin (the active form of B12; holoTC) levels in serum and semen. Both seminal and serum concentrations of holoTC and CBL were lower in morbidly obese compared to lean men, although the difference did not reach any statistical significance for serum holoTC. Seminal CBL and holoTC were significantly higher than serum levels in both groups. Significant positive correlations were observed between seminal holoTC and total sperm motility (r = 0.394, p = 0.012), sperm concentration (r = 0.401, p = 0.009), total sperm number (r = 0.343, p = 0.028), and negative correlation with semen pH (r = -0.535, p = 0.0001). ROC analysis supported seminal holoTC as the best predictor of sperm number (AUC = 0.769 ± 0.08, p = 0.006). Our findings suggest that seminal rather than serum levels of holoTC may represent a good marker of semen quality in morbidly obese subjects.

Conversion from laparoscopic adjustable gastric banding (LAGB) and laparoscopic sleeve gastrectomy (LSG) to one anastomosis gastric bypass (OAGB): preliminary data from a multicenter retrospective study.

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is the most commonly performed bariatric procedure, while laparoscopic adjustable gastric banding (LAGB) has been for a decade one of the most popular interventions for weight loss. After LSG and LAGB, some patients may require a second surgery due to weight regain or late complications. One anastomosis gastric bypass (OAGB) is a promising bariatric procedure, which provides effective long-term weight loss and has a favorable effect on type 2 diabetes. OBJECTIVES: To retrospectively analyze data from 10 Italian centers on conversion from LAGB and LSG to OAGB. SETTING: High-volume centers for bariatric surgery. METHODS: Prospectively collected data from 10 high-volume centers were retrospectively reviewed. Body mass index (BMI), percentage of excess BMI loss, reasons for redo, remission from co-morbidities (hypertension, diabetes, gastroesophageal reflux, and dyslipidemia), and major complications were recorded. RESULTS: Three hundred patients were included in the study; 196 patients underwent conversion from LAGB to OAGB and 104 were converted from LSG. BMI was 45.1 ± 7 kg/m2 at the time of first intervention, 41.8 ± 6.3 kg/m2 at redo time, and 30.5 ± 5.5 kg/m2 at last follow-up appointment. Mean percentage of excess BMI loss was 13.2 ± 28.2 at conversion and 73.4 ± 27.5 after OAGB. Remission rates from hypertension, diabetes, gastroesophageal reflux, and dyslipidemia were 40%, 62.5%, 58.7% and 52%, respectively. Mean follow-up was 20.8 (range, 6-156) months and overall complications rate was 8.6%. CONCLUSION: Our data show that OAGB is a safe and effective revisional procedure after failed restrictive bariatric surgery.

Circumferential abdominoplasty.

BACKGROUND: In Italy, 34.2% of the population has a BMI higher than 25, and another 9.8% of the population has a BMI higher than 30. In Italy, there are 4 million and 700,000 obese people. Bariatric surgery has evolved as a very effective therapy for morbid obesity. After such dramatic weight loss, patients are usually left with redundant skin and unwieldy subcutaneous tissue. The circumferential truncal excess cannot be corrected by a regular abdominoplasty alone. In this group of patients, lateral excess can actually be over accentuated by a traditional abdominoplasty. In our institution, we are used performing abdominoplasty according to Pascal-Le Louarn's surgical technique. In our cases, the adoption of this technique has been successful with a high rate of very satisfied patients, no major complications and few minor complications primarily in the smoker patients. METHODS: The charts of 41 consecutive circumferential abdominoplasty were reviewed. The preoperative markings, the surgical technique, the post-operative course, and the complications are described. RESULTS: The average operative time was 220 min. The average lipoaspirate was 1,600 cc. The mean weight loss during the surgery was 3.4 kg. There were 18 immediate complications, including 11 seromas, and 7 partial wound dehiscences. There were 26 late complications, including 8 hypertrophic scars and 18 local hypoestesia. All seromas were resolved within 3 weeks. All patients were satisfied. CONCLUSION: Circumferential abdominoplasty performed with Pascal-Le Louarn's surgical technique is an effective, appropriate, and safe method to treat patients with lipodistrophy of the trunk following massive weight loss.

Intussusception After Roux-en-Y Gastric Bypass: Laparoscopic Management.

INTRODUCTION: Intussusception represents an uncommon cause of intestinal obstruction after Rouxen-Y gastric bypass. Symptoms are not specific and clinical presentation may vary from acute intestinal obstruction with or without bowel necrosis to intermittent or chronic pain. CT scan is the diagnostic test of choice. MATERIALS AND METHODS: A 38-year-old woman who had undergone RYGBP 5 months prior was admitted to our Emergency Department with acute abdominal pain, alimentary and bilious vomiting, and fever. A CT scan revealed an intussusception after the anastomosis and dilatation of the biliopancreatic limb and the gastric remnant. An emergency laparoscopic exploration was performed. RESULTS: The patient undergoes an explorative laparoscopy. A bowel intussusception starting distally at the jejunojejunostomy and involving the latter is discovered. The common channel is divided first, and after that, the alimentary limb is resected. The biliary limb is identified, marked, and finally divided. A side-to-side jejunojejunal anastomosis is created between the alimentary limb and the common limb. Finally, the anastomosis between the common limb and the biliopancreatic limb is fashioned about 30 cm distally from the latter anastomosis. The total operative time was 130 min. Postoperative course was uneventful, and the patient was discharged on the fifth postoperative day. CONCLUSION: Although rare, intussusception after RYGBP must be considered as a possible cause of intestinal obstruction. In case of a small bowel intussusception, a surgical resection is recommended. A laparoscopic approach to treat bowel intussusception after RYGBP is safe and feasible.

Massive Weight Loss Obtained by Bariatric Surgery Affects Semen Quality in Morbid Male Obesity: a Preliminary Prospective Double-Armed Study.

OBJECTIVES: The aim of this study is to evaluate the effect of massive weight loss on the seminal parameters at 6 months from bariatric surgery. DESIGN: Two-armed prospective study performed in 31 morbidly obese men, undergoing laparoscopic roux-en-Y-gastric bypass (n = 23) or non-operated (n = 8), assessing sex hormones, conventional (sperm motility, morphology, number, semen volume), and non-conventional (DNA fragmentation and seminal interleukin-8), semen parameters, at baseline and after 6 months from surgery or patients' recruitment. RESULTS: In operated patients only, a statistically significant improvement in the sex hormones was confirmed. Similarly, a positive trend in the progressive/total sperm motility and number was observed, though only the increase in semen volume and viability was statistically significant (Δ = 0.6 ml and 10%, P < 0.05, respectively). A decrease in the seminal interleukin-8 levels and in the sperm DNA fragmentation was also present after bariatric surgery, whereas these parameters even increased in non-operated subjects. Age-adjusted multivariate analysis showed that the BMI variations significantly correlated with the changes in the sperm morphology (ß = -0.675, P = 0.025), sperm number (ß = 0.891, P = 0.000), and semen volume (r = 0.618, P = 0.015). CONCLUSION: The massive weight loss obtained with bariatric surgery was associated with an improvement in some semen parameters. The correlations found between weight loss and semen parameter variations after surgery suggest that these might occur early downstream of the testis and more slowly than the changes in the sex hormones.
