RESUMO
BACKGROUND: Medical treatment, including glyceryl trinitrate ointment, represents the first step for the management of chronic anal fissure. However, glyceryl trinitrate ointment is associated with headache and, consequently, a high withdrawal rate of the treatment. OBJECTIVE: The aim of the present study was to evaluate the effect of the topical application of tocopherol acetate ointment on pain relief and chronic anal fissure epithelialization, comparing it with the effect of a standard treatment with glyceryl trinitrate ointment. DESIGN: This is a 2-parallel-group, single-center, randomized controlled, intent-to-treat clinical trial. SETTINGS: This study was conducted at the Garcilaso Clinic affiliated with Universidad Alfonso X (Madrid, Spain). PATIENTS: Patients with chronic anal fissure were selected. INTERVENTIONS: Patients were randomly assigned into 2 groups: patients receiving tocopherol acetate ointment and patients receiving glyceryl trinitrate ointment. MAIN OUTCOME MEASURES: The primary end point was quantification of anal pain 8 weeks after beginning the treatment as measured by a Visual Analogue Scale ranging from 0 to 100 mm. The secondary end points were the healing rate (during the treatment period of 8 weeks) and the recurrence rate. RESULTS: One hundred sixty consecutive patients were treated, 80 in each group. By 8 weeks after treatment, mean anal pain score declined by 56.2 mm in the glyceryl trinitrate ointment group compared with a mean anal pain score decline of 67.1 mm in the tocopherol acetate ointment group (mean difference, 10.9 mm (95% CI, 4.3-18.6); p = 0.018). Sixteen weeks after finishing the therapy, the recurrence rate was 13.2% in the glyceryl trinitrate ointment group vs 2.9 in the tocopherol acetate ointment group (p = 0.031). LIMITATIONS: Limitations of the study include the absence of manometric measurements of the internal anal sphincter before and after the treatments and the use of glyceryl trinitrate ointment as an active comparator, whereas calcium channel blockers are actually the standard treatment. CONCLUSIONS: Anal pain was significantly lower in the tocopherol acetate ointment group than in the glyceryl trinitrate ointment group at 8 weeks after treatment. Tocopherol acetate ointment achieved a greater healing rate and a lower recurrence rate 16 weeks after finishing the treatment. See Video Abstract at http://links.lww.com/DCR/B751.

Sin embargo, la pomada de trinitrato de glicerilo se asocia con cefalea y, en consecuencia, una alta tasa de cancelación del tratamiento.OBJETIVO:El objetivo del presente estudio fue evaluar el efecto de la aplicación tópica de pomada de acetato de tocoferol en el alivio del dolor y la epitelización de la fisura anal crónica, comparándolo con el efecto de un tratamiento estándar con pomada de trinitrato de glicerilo.DISEÑO:Ensayo clínico con intención de tratar controlado, aleatorizado, de un solo centro, con dos grupos paralelos.ESCENARIO:Clínica Garcilaso adscrita a la Universidad Alfonso X (Madrid, España).PACIENTES:Pacientes con fisura anal crónica.INTERVENCIONES:Los pacientes fueron aleatorizados en 2 grupos: pacientes que recibieron pomada de acetato de tocoferol y pacientes que recibieron pomada de trinitrato de glicerilo.PRINCIPALES MEDIDAS DE RESULTADO:El criterio de valoración principal fue la cuantificación del dolor anal 8 semanas después de comenzar el tratamiento, medido por la escala analógica visual que varía de 0 a 100 mm. Los criterios de valoración secundarios fueron la tasa de curación (durante el período de tratamiento de 8 semanas) y la tasa de recurrencia.RESULTADOS:Se trataron ciento sesenta pacientes consecutivos, 80 en cada grupo. A las ocho semanas después del tratamiento, la puntuación media de dolor anal se redujo en 56.2 mm en el grupo de pomada de trinitrato de glicerilo en comparación con una disminución de la puntuación de dolor anal medio de 67.1 mm en el grupo de pomada de acetato de tocoferol (diferencia media: 10.9 mm (intervalo de confianza del 95%; 4.3 a 18.6; p = 0.018) Dieciséis semanas después de finalizar la terapia, la tasa de recurrencia fue del 13.2% en el grupo de pomada de trinitrato de glicerilo frente a 2.9 en el grupo de pomada de acetato de tocoferol (p = 0.031).LIMITACIONES:Ausencia de medidas manométricas del esfínter anal interno antes y después de los tratamientos. Ungüento de trinitrato de glicerilo como comparador activo, mientras que los bloqueadores de los canales de calcio son en realidad el tratamiento estándar de oro.CONCLUSIONES:El dolor anal fue significativamente menor en el grupo de ungüento de acetato de tocoferol que en el grupo de ungüento de trinitrato de glicerilo a las 8 semanas después del tratamiento. La pomada de acetato de tocoferol logró una mayor tasa de curación y una menor tasa de recurrencia 16 semanas después de finalizar el tratamiento.

A 77-year-old male underwent a colonoscopy because of a positive fecal occult blood test. A polyp was removed from the rectum, 12 cm from the anal margin, with a hyperplastic appearance, covered by a cap of whitish fibrinoid exudate. The pathological report reported a hyperplastic polyp with foci of bone metaplasia in the lamina propria.

BACKGROUND: Surgical site infections (SSI) have an important impact on morbidity and mortality. OBJECTIVE: This study, therefore, sought to assess the effect of a surgical care bundle on the incidence of SSI in colorectal surgery. METHODS: We conducted a quasi-experimental intervention study with reference to the introduction of a surgical care bundle in 2011. Our study population, made up of patients who underwent colorectal surgery, was divided into the following two periods: 2007-2011 (pre-intervention) and 2012-2017 (post-intervention). The intervention's effect on SSI incidence was analyzed using adjusted odds ratios (OR). RESULTS: A total of 1,727 patients were included in the study. SSI incidence was 13.0% before versus 11.6% after implementation of the care bundle (OR: 0.88, 95% confidence interval: 0.66-1.17, p = 0.37). Multivariate analysis showed that cancer, chronic obstructive pulmonary disease, neutropenia, and emergency surgery were independently associated with SSI. In contrast, laparoscopic surgery proved to be a protective factor against SSI. CONCLUSIONS: Care bundles have proven to be very important in reducing SSI incidence since the measures that constitute these protocols are mutually reinforcing. In our study, the implementation of a care bundle reduced SSI incidence from 13% to 11.6%, though the reduction was not statistically significant.

BACKGROUND: Posterior tibial nerve stimulation (PTNS) is a minimally invasive approach with little adverse effects, but obtaining good results as shown in the different scales for the evaluation of the severity of incontinence. The aim of this study was to determine the effects of PTNS based on manometric determinations of the anal sphincter and severity during a period of treatment of 6 months (18 sessions). PATIENTS AND METHODS: A prospective interventional study of patients with fecal incontinence was performed. Subjects underwent one 30-min session every week for 12 weeks, followed by 6 sessions every 2 weeks. The effect on incontinence was evaluated by means of St. Marks and defecatory urgency scales, and manometry. RESULTS: Seventy-three patients were included. At baseline, 28.8% of the patients had a retention time of less than 1 min. At 12 weeks, 39.7% of the patients presented a retention time to 5-10 min and at 18 weeks 37% presented it over 10 min. At baseline, mean St Marks score was 15.1 + 5.1, improving after 12 weeks of treatment to 8.9 + 5 (p < 0.001). After 18 sessions, a greater improvement was observed up to 4 + 4.8 (p < 0.001). Maximum resting pressure showed a significant increase after treatment (mean increase 9.8 mmHg; p = 0.006). Similarly, maximum squeeze pressure also presented a significant augmentation (mean increase 25.3 mmHg; p = 0.002). CONCLUSION: Eighteen sessions of PTNS, divided in 12 weekly sessions and 6 sessions every 2 weeks, have shown to obtain benefits, reducing the St. Marks and the defecatory urgency scores, and increasing the manometric values.

BACKGROUND: The use of ultrasonography to assist needle placement during transverse abdominal plane (TAP) technique has provided direct visualization of surround anatomical musculature and facial planes. However, the increased girth in patients undergoing bariatric surgery is challenging to visualize via ultrasonography which may lead to poor postoperative analgesia. OBJECTIVE: The aim of the study is to investigate whether the addition of postoperative laparoscopic-guided TAP block as part of a multimodal analgesic regimen within the ERAS protocol compared to no block provides better postoperative analgesia in patients undergoing one-anastomosis gastric bypass surgery. PATIENTS AND METHODS: A prospective clinical trial was performed. Patients were randomized into two groups: patients undergoing postoperative laparoscopic-guided TAP (TAP-lap) and patients not receiving TAP-lap (Control). Multimodal analgesia included preoperative port-site infiltration with Bupivacaine 0.25% in both groups and systemic Acetaminophen. Pain quantification as measured by visual analogic scale (VAS) was assessed at 6 and 24 h after surgery, and 24-h postoperative opioid consumption. RESULTS: One hundred and forty patients were included, 70 in each group. The mean operation time was 78.5 ± 14.4 min in TAP-lap and 75.9 ± 15.6 min in Control (NS). The mean postoperative pain, as measured by VAS, 6 h after surgery was 23.1 ± 11.3 mm in TAP-lap and 41.8 ± 16.2 mm in Control (p = 0.001). 24 h after surgery was 16.6 ± 11.4 mm in TAP-lap and 35.4 ± 12.7 mm in Control (p = 0.001). Morphine rescues were necessary in 14.2% in Control and 2.8% in TAP-lap (p = 0.035). CONCLUSION: Laparoscopic-guided TAP block as part of a multimodal analgesia regimen can reduce postoperative pain and opioid consumption, without increasing operative time.

BACKGROUND: Bariatric surgery is often performed not only to lose weight, but also to improve obesity-related comorbidities. A certain metabolic effect of the bariatric techniques has been demonstrated, as the improvement or even remission of comorbidities is patent, before having lost a relevant amount of weight. The autonomic innervation of diverse viscera by the vagus nerve has been hypothesized to participate in it. We aimed to evaluate the ponderal and metabolic impact of the preservation of the hepatic branch of the vagus in type 2 diabetic (T2D) patients undergoing one-anastomosis gastric bypass (OAGB). PATIENTS AND METHODS: We conducted a prospective study on patients with a preoperative diagnosis of morbid obesity and T2D, who underwent an OAGB. Preservation of the hepatic branch of the vagus was carried out in the first 14 patients (Group 1), whereas in another 14 patients it was sectioned. Ponderal and metabolic outcomes were assessed 1 and 2 years after surgery. RESULTS: The length of the biliary limb was 210 cm in both groups. Postoperative BMI or excess BMI loss was not significantly different between groups. The patients included in Group 1 showed a statistically greater improvement in glycemic and lipid variables. CONCLUSION: The preservation of the hepatic branch of the vagus in an OAGB leads to more favorable postoperative glycemic and lipid profiles.

BACKGROUND: Ideal jejunal and ileal lengths in bariatric/metabolic procedures to be left in alimentary continuity still remain unclear. We aimed to evaluate different lengths of biliopancreatic limb (BPL) and common limb (CL) performed in a series of patients submitted to OAGB, and correlate them with weight loss and nutritional deficits. PATIENTS AND METHODS: A prospective observational study of 350 consecutive morbidly obese patients undergoing OAGB was performed. BPL and CL lengths were determined intraoperatively; BPL/TBL and CL/TBL ratios were then calculated. Anthropometric variables, remission of comorbidities and specific supplementation needs were recorded at 1, 2 and 5 years after surgery. RESULTS: Three hundred patients were included for final analysis. BPL length and BPL/TBL ratio directly correlated with Units of BMI lost (UBMIL). Conversely, CL length and CL/TBL ratio showed an inverse correlation with UBMIL. Establishing a BMI ≤ 25 kg/m2 as ideal, the most accurate AUC, to predict achieving an ideal BMI at 1, 2 and 5 years after surgery, was obtained for the CL/TBL ratio, followed by the CL length at 1, 2 and 5 years. An ideal range was established between 0.40 and 0.43 for the CL/TBL ratio, and 200 to 220 cm for the CL length. Among these ranges, there were no cases of protein or calorie malnutrition. CONCLUSION: TBL measurement is essential to obtain optimal outcomes after OAGB, both in terms of excellent weight loss and remission/improvement of comorbidities, as well as with a low risk of nutritional deficiencies. The CL/TBL ratio, followed by CL length, are the most accurate parameters to predict a 5-year postoperative BMI ≤ 25 kg/m2.

BACKGROUND: One-Anastomosis Gastric Bypass (OAGB) has exponentially increased in the last decade, as it is associated with very low complications, mortality, readmissions and reoperations rates, and shows excellent short- and long-term benefits of weight loss and resolution of comorbidities. The aim of this study was to compare the effect of SG, RYGB, and OAGB, on short- and long-term weight loss and comorbidities resolution. METHODS: A prospective randomized clinical study of all morbidly obese patients undergoing SG, RYGB, and OAGB, as primary bariatric procedures, was performed. Patients were randomly assigned into 3 groups: those patients undergoing SG, those ones undergoing RYGB and those ones undergoing OAGB. BMI, excess BMI loss (EBMIL) and remission of type 2 diabetes (T2DM), hypertension (HT), and dyslipidemia (DL) were assessed. RESULTS: 600 patients were included in the study, 200 in each group. Follow-up rate at 5 years postoperatively was 91% in SG group, 92% in RYGB, and 90% in OAGB. OAGB achieves significantly greater EBMIL than RYGB and SG at 1, 2, and 5 years (p < 0.001, respectively). At 5 years, OAGB achieves significantly greater remission of T2DM (p = 0.027), HT (p = 0.006), and DL (p < 0.001) than RYGB and SG. RYGB did not show significant superiority than SG in short- and long-term remission of T2DM and HT, but achieves greater remission of DL (p < 0.001). CONCLUSION: OAGB achieves superior mid- and long-term weight loss than RYGB and SG. There are no significant differences in weight loss between SG and RYGB at 1, 2, and 5 years. OAGB achieves better short- and long-term resolution rates of DM, HT, and DL than SG and RYGB. RYGB and SG obtain similar T2DM and HT remissions, but RYGB reaches significantly greater rates of DL remission. ClinicalTrials.gov Identifier: NCT03467646.

BACKGROUND: Surgical site infection (SSI) prevention bundles include the simultaneous use of different measures, which individually have demonstrated an effect on prevention of SSI. The implementation of bundles can yield superior results to the implementation of individual measures. The aim of this study was to address the effect of the application of a bundle including intraperitoneal lavage with antibiotic solution, fascial closure with Triclosan-coated sutures and Mupirocin ointment application on the skin staples, on the surgical site infection after elective laparoscopic colorectal cancer surgery. METHODS: A prospective, randomized study was performed, including patients with diagnosis of colorectal neoplasms and plans to undergo an elective laparoscopic surgery. The patients were randomized into two groups: those patients following standard bundles (Group 1) and those ones following the experimental bundle with three additional measures, added to the standard bundle. Incisional and organ space SSI were investigated. The study was assessor-blinded. RESULTS: A total of 198 patients were included in the study, 99 in each group. The incisional SSI rate was 16% in Group 1 and 2% in Group 2 [p = 0.007; RR = 5.6; CI 95% (1.4-17.8)]. The organ-space SSI rate was 4% in Group 1 and 0% in Group 2 [p = 0.039; RR = 1.7; CI 95% (1.1-11.6)]. Median hospital stay was 5.5 days in Group 1 and 4 days in Group 2 (p = 0.028). CONCLUSIONS: The addition of intraperitoneal lavage with antibiotic solution, fascial closure with Triclosan-coated sutures and Mupirocin ointment application on the skin staples, to a standard bundle of SSI prevention, reduces the incisional and organ-space SSI and consequently the hospital stay, after elective laparoscopic colorectal cancer surgery (ClinicalTrials.gov Identifier: NCT03081962).

Introduction: The essence of Enhanced Recovery After Surgery (ERAS) programs is the multimodal approach, and many authors have demonstrated safety and feasibility in fast track bariatric surgery. According to this concept, a multidisciplinary ERAS program for bariatric surgery has been developed by the Spanish Fast Track Group (ERAS Spain). The aim of this study was to analyze the initial implementation of this Spanish National ERAS protocol in bariatric surgery, comparing it with a historical cohort receiving standard care. Material and methods: A multi-centric prospective study was performed, including 233 consecutive patients undergoing bariatric surgery during 2015 and following ERAS protocol. It was compared with a historical cohort of 286 patients, who underwent bariatric surgery at the same institutions between 2013 and 2014 and following standard care. Compliance with the protocol, morbidity, mortality, hospital stay and readmission were evaluated. Results: Bariatric techniques performed were Roux-en-Y gastric bypass and sleeve gastrectomy. There were no significant differences in complications, mortality and readmission. Postoperative pain and hospital stay were significantly lower in the ERAS group. The total compliance to protocol was 80%. Conclusion: The Spanish National ERAS protocol is a safe issue, obtaining similar results to standard care in terms of complications, reoperations, mortality and readmissions. It is associated with less postoperative pain and earlier hospital discharge.

BACKGROUND: Current therapeutic guidelines for the treatment of chronic anal fissure establish a medical approach as the first step. Glyceryl trinitrate ointment is the most popular of the available topical treatments in Spain but it is associated with the appearance of headache. OBJECTIVE: The purpose of this study was to compare the compliance rate among patients receiving glyceryl trinitrate treatment for chronic anal fissure with that among patients receiving percutaneous posterior tibial nerve stimulation. DESIGN: This was a prospective randomized study. SETTINGS: The study was conducted at Garcilaso Clinic (Madrid, Spain). PATIENTS: Subjects with persistent anal fissure despite hygiene and dietary measures applied over at least a 6-week period were included. INTERVENTIONS: Study interventions were perianal application of glyceryl trinitrate ointment (twice daily for 8 weeks) and percutaneous posterior tibial nerve stimulation (30-minute session 2 days per week for 8 weeks). MAIN OUTCOME MEASURES: Compliance with the treatment and healing rate of chronic anal fissure in patients receiving glyceryl trinitrate ointment or undergoing percutaneous posterior tibial nerve stimulation were evaluated. RESULTS: Forty patients were included in each group. In the glyceryl trinitrate ointment group, 15% of the patients discontinued treatment because of disabling headaches. There were no adverse effects or treatment withdrawals in the percutaneous posterior tibial nerve stimulation group (p = 0.033). After 8 weeks of treatment, the healing rate in the percutaneous posterior tibial nerve stimulation group was 87.5% vs 65.0% in the glyceryl trinitrate ointment group (p = 0.018). LIMITATIONS: Because the patients were not blinded to the treatment, we cannot rule out a placebo effect derived from the needle insertion in the percutaneous posterior tibial nerve stimulation group. CONCLUSIONS: Percutaneous posterior tibial nerve stimulation is a safe and effective alternative that is in some ways superior to glyceryl trinitrate ointment for the treatment of chronic anal fissure.

INTRODUCTION: Although bariatric surgery is actually mainly performed laparoscopically, analgesic optimization continues being essential to reduce complications and to improve the patients' comfort. The aim of this study is to evaluate the postoperative pain after analgesia iv exclusively, or associated with epidural analgesia or port-sites infiltration with bupivacaine. PATIENTS AND METHODS: A prospective randomized study of patients undergoing laparoscopic sleeve gastrectomy between 2012 and 2014 was performed. Patients were divided into three groups: Analgesia iv exclusively (Group 1), epidural analgesia + analgesia iv (Group 2) and port-sites infiltration + analgesia iv (Group 3). Pain was quantified by means of a Visual Analogic Scale, and morphine rescue needs were determined 24 h after surgery. RESULTS: A total of 147 were included. Groups were comparable in age, gender and BMI. There were no differences in operation time, complications, mortality or hospital stay between groups. Median pain 24 h after surgery was 5 in Group 1, 2.5 in Group 2 and 2 in Group 3 (P = 0.01), without statistically significant differences between Groups 2 and 3. In Group 1, morphine rescue was necessary in 16.3 % of the cases, 2 % in Group 2 and 2 % in Group 3 (P = 0.014), without statistically significant differences between Groups 2 and 3. CONCLUSION: Epidural analgesia and port-sites infiltration with bupivacaine, associated with analgesia iv, reduce the postoperative pain, when compared with analgesia iv exclusively.

INTRODUCTION: The performance of most bariatric procedures within an Enhanced Recovery After Surgery program has resulted in significant advantages, including a reduction in the length of hospital stay to 2-3 days. However, some postoperative complications may appear after the patient has been discharged. The aim of this study was to investigate the efficacy of various acute-phase parameters determined 24 h after a laparoscopic sleeve gastrectomy for predicting staple line leak in the postoperative course. PATIENTS AND METHODS: A prospective study of 208 morbidly obese patients undergoing laparoscopic sleeve gastrectomy as bariatric procedure between 2012 and 2015 was performed. Blood analysis was performed 24 h after surgery. Acute-phase parameters (C-reactive protein, procalcitonin, fibrinogen, and White Blood Cell count) were investigated. RESULTS: Staple line leak appeared in eight patients (3.8%). Using receiver operating characteristic analysis at 24 h postoperatively, a cutoff level of CRP at 9 mg/dL achieved 85% sensitivity and 90% specificity for predicting staple line leak, a cutoff level of procalcitonin at 0.85 ng/mL achieved 70% sensitivity and 90% specificity, and a cutoff level of fibrinogen at 600 mg/dL achieved 80% sensitivity and 87.5% specificity. CONCLUSION: An elevation of CRP > 9 mg/dL, procalcitonin > 0.85 ng/mL and fibrinogen > 600 mg/dL should alert the surgeon the possibility of occurrence of postoperative staple line leak.

The portal vein is formed by the confluence of the splenic and superior mesenteric veins, which drain the spleen and small intestine respectively. Occlusion of the portal vein by thrombus typically occurs in patients with cirrhosis and/or prothrombotic disorders. However, portal vein thrombosis (PVT) can also happen after determined surgeries. Moreover, PVT can have serious consequences depending on the location and extent of the thrombosis, including hepatic ischemia, intestinal ischemia, portal hypertension In this chapter, we will review the incidence, management and prophylaxis of PVT after splenectomy, pancreas transplantation, pancreatic surgery and in the setting of acute and chronic pancreatitis.

Obesity itself is associated with an increased risk of thromboembolic events. Moreover, most bariatric procedures actually are performed by laparoscopic approach, implying an increased intraabdominal pressure during the surgical procedure that may favor the development of thrombus. Therefore, bariatric surgery is considered a high-risk procedure for thromboembolic events. Actual recommendations are to include low molecular weight heparins (LMWH) and compression stockings in the primary prophylaxis of thromboembolic events. Following these measures, a routine screening of thromboembolic complications with imaging tests is not recommended.

Jejunal pseudodiverticulosis is an uncommon entity. Pseudodiverticulum are usually asymptomatic and an incidental finding. They can have a less frequent acute onset with perforation, obstruction or bleeding and they could have high morbidity and mortality. We report three patients who debuted with an acute abdomen.

BACKGROUND: After bariatric surgery an improvement or even complete resolution of nonalcoholic fatty liver disease (NAFLD) in morbidly obese patients is achieved, but little is known about the effect of laparoscopic sleeve gastrectomy (LSG). PATIENTS AND METHODS: A prospective observational study of patients undergoing LSG was performed. An abdominal ultrasonography and blood sample extraction (investigating liver enzymes and lipid profile) were performed preoperatively and 12 months after surgery. RESULTS: Fifty patients were included in the study. Preoperatively, 84% of the patients presented liver steatosis. A significant reduction of steatosis could be observed 12 months after surgery (p < .001). Preoperative degree of steatosis showed a direct correlation with AST (p = .008) and ALT (p = .007) and an inverse correlation with HDL-cholesterol (p = .019). The reduction of liver steatosis showed an inverse correlation with the increase of HDL-cholesterol between pre- and postoperative determinations (p = .008). CONCLUSIONS: Liver steatosis, as measured by ultrasonography, improves after sleeve gastrectomy, achieving a complete resolution in 90% of the cases. Preoperative steatosis correlates directly with AST and ALT levels and inversely with HDL-cholesterol. The postoperative increase of HDL-cholesterol shows an inverse correlation with liver steatosis improvement, suggesting that it could be a good marker for monitoring the postoperative liver status.

Spontaneous rupture of the spleen without traumatic cause is an unfrequent entity, usually related with pathologic spleens. We present a case of spontaneous rupture of an histologically normal spleen with splenomegalia secondary to smoking habit. The hemoperitoneum caused by the spontaneous rupture of the spleen mimmicked a hollow viscera perforation.

INTRODUCTION: Endocrine pancreatic segregation is regulated by the autonomic nervous system. The parasympathetic system stimulates insulin production by the beta cells and inhibits the adrenergic discharge by the sympathetic nervous system. The aim of this study was to evaluate the effect of percutaneous neurostimulation (PENS) of dermatome T7, generating a somato-autonomic reflex, whose efferent pathway are the vagal branches that specifically stimulate the pancreas. The effect of this treatment on glycemia, insulin secretion and insulin resistance was investigated. METHODS: A prospective randomized clinical trial was performed. Patients with Body Mass Index>30kg/m(2) and diagnosis of diabetes mellitus treated with Metformin were included. Patients were divided into 2 groups: Patients undergoing PENS of dermatome T7 (12 sessions of 30minutes weekly) associated with a 1,200 Kcal/day diet (Group 1) and patients following only a 1,200Kcal/day diet (Group 2). All the patients underwent a blood sample extraction before the treatment and 7 days after finishing it. RESULTS: 60 patients were included: 30 in each group. After finishing the treatment, in Group 1 a significant decrease in glycemia (Mean decrease of 62,1mg/dl; P=.024) and HOMA (Mean decrease 1.37; P=.014) was observed. In Group 2, no significant differences between pre and post-treatment values were observed. CONCLUSION: PENS of dermatome T7 associated with a 1,200Kcal/day diet achieves a greater reduction in glycemia and insulin resistance than with diet exclusively after 3 months of treatment.
