Splenic and concomitant liver abscess after laparoscopic sleeve gastrectomy

Introduction: Laparoscopic sleeve gastrectomy (LSG) is a safe and effective procedure for losing weight and gaining control of obesity-related comorbidities. However, it is associated with postoperative complications such as bleeding, leak, and midgastric stenosis. Splenic and hepatic abscesses have been reported as unusual and rare complications after primary LSG. We report a case of splenic and concomitant hepatic abscesses after primary LSG, successful minimally invasive management, and midterm follow-up. Case Description: We report a complex case of splenic abscess with satellite hepatic abscess plus splenic thrombosis (0.1%) diagnosed 67 days after LSG. This unusual complication was managed by a minimally invasive approach (spleen sparing) with complete resolution after 35 days. After 18 months of follow-up, the patient showed complete resolution of the splenic and liver abscesses and progressive loss of excess weight. Conclusion: In high-volume centers, rare and life-threatening complications such as splenic and hepatic abscesses may be observed. The minimally invasive approach could represent an effective option of avoiding splenectomy in selected case

Titanium versus absorbable tacks comparative study (TACS): a multicenter, non-inferiority prospective evaluation during laparoscopic repair of ventral and incisional hernia: study protocol for randomized controlled trial

BACKGROUND: Laparoscopic repair of ventral and incisional hernias has gained popularity since many studies have reported encouraging results in terms of outcomee and recurrence. Choice of mesh and fixation methods are considered crucial issues in preventing recurrences and complications. Lightweight meshes are considered the first choice due to their biomechanical properties and the ability to integrate into the abdominal wall. Titanium helicoidal tacks still represent the "gold standard" for mesh fixation, even if they have been suggested to be involved in the genesis of post-operative pain and complications. Recently, absorbable tacks have been introduced, under the hypothesis that there will be no need to maintain a permanent fixation device after mesh integration. Nevertheless, there is no evidence that absorbable tacks may guarantee the same results as titanium tacks in terms of strength of fixation and recurrence rates. The primary end point of the present trial is to test the hypothesis that absorbable tacks are non-inferior to titanium tacks in laparoscopic incisional and ventral hernia repair (LIVHR) by lightweight polypropylene mesh, in terms of recurrence rates at 3-year follow-up. Surgical complications, post-operative stay, comfort and pain are secondary end points to be assessed. METHODS/DESIGN: Two hundred and twenty patients with ventral hernia will be randomized into 2 groups: Group A (110) patients will be submitted to LIVHR by lightweight polypropylene mesh fixed by titanium tacks; Group B (110) patients will be submitted to LIVHR by lightweight polypropylene mesh fixed by absorbable tacks. DISCUSSION: A few retrospective studies have reported similar results when comparing absorbable versus non-absorbable tacks in terms of intraoperative and early post-operative outcomes. These studies have the pitfalls to be retrospective evaluation of small series of patients, and the reported results still need to be validated by larger series and prospective studies. The aim of the present trial is to investigate and test the non-inferiority of absorbable versus non-absorbable tacks in terms of hernia recurrence rates, in order to assess whether the use of absorbable tacks may achieve the same results as non-absorbable tacks in mid-term and long-term settings

Is type 2 diabetes really resolved after laparoscopic sleeve gastrectomy? Glucose variability studied by continuous glucose monitoring

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 (<140 mg/dL) at 120 minutes OGTT. These interesting data could help clinicians to better individualize patients in which diabetes is not resolved and who could need more attention in order to prevent chronic complications of diabetes

Laparoscopic sleeve gastrectomy in adolescents with or without syndromic obesity: two years follow-up

Introduction Childhood obesity is an emerging health problem. Surgical treatment of obese adolescents, particularly those affected by congenital syndrome, represents a controversial issue. The aim of this multicenter study was to retrospectively assess the results of laparoscopic sleeve gastrectomy (LSG) in a cohort of adolescents affected by morbid obesity, with or without congenital syndromes. Materials and methods Forty-one obese (BMI 49 ± 6 kg/m2) adolescents with mean age of 16 ± 3 years (58.5% with previous intragastric balloon failure), and subjected to LSG, were retrospectively evaluated for complications rate, % excess weight loss (%EWL), and inhibition of co-morbidities after 2 years of follow-up. Results All the operations were completed laparoscopically and no intra-operative complications were recorded. No mortality was recorded while peri- or post-operative complications only occurred in two patients (4.9%). The EWL% at 6, 12, and 24 months were 42.3, 58.3, and 59.4, respectively. %EWL was comparable (p = 0.7) between non-syndromic and syndromic obese adolescents at 24 months. Conversely patients with previous intragastric balloon surgery had a significant lower EWL (%) at 24 month (p < 0.01). Moreover, at the same time point, co-morbidity resolution rate was 78.2% while improvement rate was 57.6%. Specifically, remission rate of type 2 diabetes (T2DM), hypertension and obstructive sleep apnea (OSA) were 71, 75 and 61%, respectively. Conclusion LSG is advantageous in the treatment of morbidly obese juveniles concerning safety, weight loss and co-morbidity control and at same time presenting, a possible effective therapeutic option for patients affected by congenital syndrom

A narrative review on bariatric ERAS

Bariatric/metabolic surgery (BMS) is the most effective treatment of morbid obesity, while Enhanced Recovery After Surgery (ERAS) after BMS represents a multimodal perioperative protocol designed to achieve early recovery for patients with peculiar characteristics. The aim of the current narrative review is to summarize and discuss the current role, the application, and the future developments of ERAS protocols in the field of BMS

A prospective evaluation on external jugular vein cut-down approach for TIVAD implantation

BACKGROUND: Totally implantable venous access devices can be implanted both by percutaneous approaches and by surgical approaches with cephalic vein or external jugular vein cut-down techniques that are related to low intraoperative complication rates. The authors report a prospective evaluation of 83 consecutive external jugular vein cut-down approaches for totally implantable venous access devices implantation. METHODS: Eighty three consecutive patients (28 M, 55 F, mean age 54.2) suffering from solid tumors (58) or hematologic diseases (25) were consecutively submitted to totally implantable venous access devices insertion through external jugular vein cut-down approach (75 on right side, 8 on left side). RESULTS: All devices were surgically implanted; no instances of intraoperative complications were detected. After a minimum follow-up of 150 days, only one case of wound hematoma and one case of device malfunction due to incorrect catheter angulation were noted. Postoperative patient satisfaction was evaluated by the use of specific questionnaire that demonstrated a good satisfaction and compliance (92.8 %) of patients with implanted devices. CONCLUSIONS: Despite the lack of controlled studies comparing external jugular vein cut-down approach vs other approaches, this approach should be considered as a tool for long-term central vein catheters positioning, both as an alternative and for primary approach

Two-stage laparoscopic biliopancreatic diversion with duodenal switch as treatment of high-risk super-obese patients: analysis of complications

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 +/- A 10.22 years with BMI of 55.2 +/- A 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 +/- A 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

Increased plasma proneurotensin levels identify NAFLD in adults with and without type 2 diabetes

Context Neurotensin (NT), an intestinal peptide released by fat ingestion, promotes lipid absorption; higher circulating NT levels are associated with type 2 diabetes (T2D), obesity, and cardiovascular disease. Whether NT is related to nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) has not been fully investigated. Objective To study the relationship between plasma proneurotensin 1 to 117 (pro-NT), a stable fragment of the NT precursor hormone, and the presence/severity of NAFLD/NASH and to unravel correlates of increased pro-NT levels. Design/Setting/Participants For this cross-sectional study, 60 obese individuals undergoing bariatric surgery for clinical purposes were recruited. The association between pro-NT and NAFLD was further investigated in 260 consecutive subjects referred to our outpatient clinics for metabolic evaluations, including liver ultrasonography. The study population underwent complete metabolic characterization; in the obese cohort, liver biopsies were performed during surgery. Main Outcome Measures Plasma pro-NT levels in relation to NAFLD/NASH. Results Obese subjects with biopsy-proven NAFLD (53%) had significantly higher plasma pro-NT than those without NAFLD (183.6 ± 81.4 vs 86.7 ± 56.8 pmol/L, P &lt; 0.001). Greater pro-NT correlated with NAFLD presence (P &lt; 0.001) and severity (P &lt; 0.001), age, female sex, insulin resistance, and T2D. Higher pro-NT predicted NAFLD with an area under receiver operating characteristic curve of 0.836 [95% confidence interval (CI), 0.73 to 0.94; P &lt; 0.001]. Belonging to the highest pro-NT quartile correlated with increased NAFLD risk (odds ratio, 2.62; 95% CI, 1.08 to 6.40) after adjustment for confounders. The association between higher pro-NT and NAFLD was confirmed in the second cohort independently from confounders. Conclusions Increased plasma pro-NT levels identify the presence/severity of NAFLD; in dysmetabolic individuals, NT may specifically promote hepatic fat accumulation through mechanisms likely related to increased insulin resistance. © 2018 Endocrine Society
