Impact of a daily legume-based meal on blood and anthropometric parameters in a group of omnivorous adults: A pilot study.

This pilot study aimed to assess the impact of substituting a traditional lunch for a vegetarian legume-based meal on blood and anthropometric parameters in a group of omnivorous adults. A one-group comparison, quasi-experimental dietary intervention was designed. A vegetarian legume-based meal was offered for 8 consecutive weeks (weekdays) to non-vegetarian individuals (n = 26), (28 years [P25 = 20.0, P75 = 35.5]; 21.9 kg/m2 [P25 = 21.3, P75 = 24.8]). Sociodemographic data, health status and lifestyle-related information were recorded. Three-day food records were used to collect food intake at baseline and at the end of the intervention. Anthropometric parameters were recorded and fasting blood analyses were performed following standard procedures. Wilcoxon signed-rank test was used for statistical comparisons. A p-value <0.05 was considered statistically significant. Participants showed a median intake of 79.8 g of cooked legumes per meal, meaning 13 (50.0%) subjects met the Portuguese daily legume intake recommendations during the intervention days. There were no statistically significant differences in anthropometric parameters. Transferrin concentration increased after 8 weeks (+12.5 mg/dL; p = 0.001). Total cholesterol concentration reduced after 8 weeks (-6 mg/dL; p = 0.041), as well as low-density lipoprotein (LDL) cholesterol (-7 mg/dL; p = 0.003). Triglycerides (+9 mg/dL; p = 0.046), fasting glucose (+2 mg/dL; p = 0.037) and HbA1c (+0.1 mg/dL; p = 0.010) concentration increased after the 2-month legume-based trial. Results suggest a cholesterol-lowering potential of legume-rich diets. However, unfavourable results regarding the impact on glucose metabolism-related biomarkers and triglyceride levels were observed. The study's limitations in design and sample size emphasise the importance of conducting further research with larger cohorts to attain more conclusive findings.

The use of the cap and underwater technique as an aid in endoscopic diagnosis and treatment of upper gastrointestinal bleeding: case series.

BACKGROUND AND AIMS: Upper GI bleeding (UGIB) is a medical emergency associated with elevated mortality and significant costs to the health care system. EGD is currently the method of choice for the diagnosis and management of these conditions. However, the location of bleeding lesions and technical difficulties in achieving endoscope stability may challenge even the most experienced endoscopists. Herein, we demonstrate the use of the cap and underwater technique as a helpful aid in these situations. METHODS: We present a case series of 4 patients with acute UGIB who underwent EGD with suboptimal endoscopic visualization or technical difficulties in identifying the source of bleeding. A transparent plastic cap was attached to the distal tip of the gastroscope, and the water immersion technique (underwater) was used for endoscopic re-evaluation of the bleeding site. RESULTS: Three patients presented with duodenal bleeding, and 1 was diagnosed with diffuse bleeding from the esophagus. The clear and accurate identification of the source of bleeding and effective hemostasis were possible after cap and underwater technique evaluation in all patients. CONCLUSION: The use of the cap and underwater technique is a simple, safe, and low-cost strategy that improves the identification and control of UGIB in locations with poor visibility and technical challenges during endoscopic evaluation.

Pancreas-preserving duodenectomy after living donor liver transplantation for invasive cytomegalovirus disease.

CMV infection plays an important role in the postoperative course following solid organ transplantation. We present the case of an 11-year-old male patient who underwent LDLT due to severe hepatopulmonary syndrome and biliary cirrhosis. Four weeks after LDLT, he developed persistent GI bleeding and was subjected to repeated endoscopic treatment and radiological arterial embolization to stop the bleeding from duodenal ulcers. Diagnostic workup was negative for CMV disease. Because the bleeding persisted, surgical treatment was indicated, and a pancreas-preserving duodenectomy was performed. Immunohistochemical staining of the surgical specimen demonstrated diffuse endothelial infiltration by CMV. Despite ganciclovir treatment, the patient developed new erosions in the jejunal mucosa and melena; ganciclovir was discontinued, and foscarnet was started, resulting in clinical improvement and the cessation of bleeding. This case highlights the technical aspects of performing a complex upper GI resection in a patient recently subjected to LDLT, taking care to avoid injury to the previous liver graft anastomosis and restore GI continuity. Moreover, CMV tissue-invasive disease compartmentalized in the GI tract may be difficult to diagnose, as indicated by the negative results of antigenemia and PCR assays and endoscopic superficial mucosal biopsies.

Septotomy and Balloon Dilation to Treat Chronic Leak After Sleeve Gastrectomy: Technical Principles.

BACKGROUND: Chronic leaks after laparoscopic sleeve gastrectomy (LSG) are often difficult to treat by endoscopy metallic stent. Septotomy has been indicated as an effective procedure, but the technical aspects have not been detailed in previous publications (Campos JM, Siqueira LT, Ferraz AA, et al., J Am Coll Surg 204(4):711, 2007; Baretta G, Campos J, Correia S, et al., Surg Endosc 29(7):1714-20, 2015; Campos JM, Pereira EF, Evangelista LF, et al., Obes Surg 21(10):1520-9, 2011). We herein present a video (6 min) demonstrating the maneuver principles of this technique, showing it as a safe and feasible approach. METHODS: A 32-year-old male, with BMI 43.4 kg/m(2), underwent LSG. On the tenth POD, he presented with a leak and initially was managed with the following approach: laparoscopic exploration, drainage, endoclips, and 20-mm balloon dilation. However, the leak remained for a period of 6 months. On the endoscopy, a septum was identified between the leak site and gastric pouch, so it was decided to "reshape" this area by septotomy. Septotomy procedure: Sequential incisions were performed using argon plasma coagulation (APC) with 2.5 flow and 50 W (WEM, SP, Brazil) over the septum in order to allow communication between the perigastric cavity (leak site) and the gastric lumen. The principles below must be followed: (1) Scope position: the endoscopist's left hand holds the control body of the gastroscope while the right hand holds the insertion tube; the APC catheter has no need to be fixed. This avoids movements and unprogrammed maneuvers. (2) Before cutting, the septum is placed in the six o'clock position on the endoscopic view, by rotating the gastroscope. (3) The septum is sectioned until the bottom of the perigastric cavity (leak site). (4) That section is made towards the staple line. (5) Just after the septotomy, a Savory-Gilliard guidewire (Cook Medical, Indiana, USA) through the scope must be inserted until the duodenum, followed by 30-mm balloon (Rigiflex®, Boston Scientific, MA, USA) insertion. The balloon catheter must be firmly held during gradual inflation (maximum 10 psi) to avoid slippage and laceration. This allows increasing the gastric lumen. (6) Septotomy by electrocautery with a needle knife (Boston Scientific, MA, USA) can be made when an intensive fibrotic septum is present; bleeding is rare in this case. In this case, the endoclip previously used was removed from the septum with forceps to avoid heat transmission. Small staples visualized in the fistula orifice were not completely removed due to technical difficulties and friable tissue. RESULTS: Two sessions were performed in 15 days, resulting in leak closure. The patient was submitted to radiological control 1 week after the second session, which revealed fistula healing, without gastric stenosis. The nasoduodenal feeding tube remained for 7 days, when the patient started oral diet. This patient was followed for 18 months without recurrence. CONCLUSIONS: Septotomy and balloon dilation were initially performed on a difficult-to-treat chronic fistula after gastric bypass and named before as stricturotomy (Campos JM, Siqueira LT, Ferraz AA, et al., J Am Coll Surg 204(4):711, 2007). This procedure allows internal drainage of the fistula and deviates oral intake to the pouch. In addition, achalasia balloon dilation treats strictures and axis deviation of the gastric chamber, promoting reduction of the intragastric pressure. Septotomy and balloon dilation are technically feasible and might be useful in selected cases for closure of chronic leaks after LSG.
