RESUMO

Introduction: Bioelectrical impedance analysis (BIA) is the most used tool in clinical practice to evaluate body composition in patients with obesity. The skeletal muscle index (SMI) defined by BIA has been proposed for the identification of sarcopenia, but there are currently no univocal cutoffs for this condition. In this study, we aimed: 1) to determine the prevalence of sarcopenia in patients with severe obesity using the current cutoffs of SMI; 2) to define new specific cutoffs; 3) to validate the new cutoffs; and 4) to re-determine the prevalence of sarcopenia. Methods: A total of 300 patients, 74% women and 26% men (mean age = 42.6 ±; 9 years), with morbid obesity (mean BMI = 46.7 ±; 6.5 kg/m2) followed by the Unit of Endocrinology from January 2014 to December 2020 were retrospectively evaluated. SMI was calculated as the skeletal muscle mass normalized for squared height through the BIA equation by Janssen et al. Results: The prevalence of sarcopenic obesity calculated using the cutoff points reported by De Rosa et al. (7.3 kg/h2 for women and 9.5 kg/h2 for men) was 2.3%. The prevalence of sarcopenia was calculated using the new cutoffs: with the cutoff obtained from the standard deviation method (8.2 kg/h2 for women and 10.2 kg/h2 for men), a prevalence of 14.7% was observed, whereas the prevalence reached 47.6% when using the cutoff calculated through the K-means unsupervised cluster (9.2 kg/h2 for women and 11.3 kg/h2 for men). The new cutoffs were validated with a second sample consisting of 300 patients with morbid obesity (BMI = 44.9 ±; 6.7 kg/m2): the rate of sarcopenic patients was still higher than that observed in the training cohort (56%). After the matching procedure (by BMI and age), the rates of sarcopenic patients were similar in both groups (50.2% in the validation group and 53% in the training group, p = 0.6). Conclusion: The new cutoffs calculated with cluster analysis could better identify sarcopenia in morbidly obese patients. However, further studies are needed to validate these cutoffs in different patient cohorts.

RESUMO

PURPOSE: Spexin is expressed by white fat tissue and other endocrine organs. A negative correlation between spexin and gluco-lipidic metabolism, energy homeostasis, and food intake has been reported. The objectives of this study are (1) to compare spexin levels between patients with obesity (study group) and normal-weight subjects (control group); (2) to evaluate spexin levels after bariatric surgery; and (3) to identify a correlation between spexin and weight loss/metabolic profile of patients with obesity. MATERIALS AND METHODS: We examined 53 patients with obesity (mean BMI 48.5 ± 9.4 kg/m2) who underwent bariatric surgery, compared to 55 normal-weight subjects. Serum spexin levels were assessed at baseline (study and control group) and at 3 and 6 months after surgery in patients with obesity. RESULTS: Spexin at baseline was significantly lower in the study group (p < 0.0001). At 3 and 6 months after bariatric surgery, spexin significantly increased compared to pre-surgical levels (p < 0.001) reaching control group levels (p = 0.08) at 6 months. In patients with obesity, pre-surgical spexin was similar in patients with and without comorbidities. No correlation between spexin and C-reactive protein (p = 0.8) and HOMA index (p = 0.5) was found. A significant negative correlation between age and pre-surgical spexin was observed (p = 0.03). At multivariable analysis, no correlation between Δ spexin and pre-surgery BMI, HOMA index, age, and 6-month TWL% was found. CONCLUSION: This study demonstrates that patients with obesity have significantly lower spexin levels than healthy subjects. After surgery, spexin levels of the study group become similar to those observed in the normal-weight group.

RESUMO

Bariatric surgery (BS) is the most effective treatment strategy for obesity. Nevertheless, a subset of patients does not reach a successful weight loss or experience long-term weight regain. Conflicting evidence exists regarding predictors of BS outcomes. We aimed to define the early factors linked to 3 year unsuccessful weight loss in order to promote a tailored close follow-up. We enrolled 443 patients who underwent BS from January 2014 to December 2018 with a 3 year follow-up. An unsuccessful BS outcome was defined as a percentage of total weight loss (%TWL) < 20. We compared the characteristics between successful and unsuccessful patients in order to identify predictor factors of unsuccess after surgery. We found that the proportion of patients with unsuccessful weight loss progressively increased from one to three years after BS. In a multiple regression model, only 1 month %TWL and sleeve gastrectomy (SG) were significantly associated with 3 year unsuccessful weight loss. We stratified our cohort in four groups according to the risk of BS unsuccess, in terms of 1 month %TWL and type of surgery (SG vs gastric bypass). Interestingly, groups showed a significant difference in terms of %TWL at each follow-up point. Patients submitted to SG with lower 1 month %TWL must be considered at higher risk of future weight regain; consequently, they require a tailored and closer follow-up.

RESUMO

A single nucleotide polymorphism in the Type 2 deiodinase (DIO2) gene (p.Thr92Ala) was found to be associated with hypertension, type 2 diabetes mellitus (T2DM), insulin resistance, and body mass index (BMI). We retrospectively evaluated 182 patients to assess whether the DIO2 p.Thr92Ala was associated with severe obesity and response to bariatric surgery. Genomic DNA was extracted from peripheral blood leukocytes before surgery. Glycemic control parameters, cardiometabolic risk biomarkers (waist circumference, lipid assessment and blood pressure) and hormonal parameters were assessed at baseline and after surgery. Based on genotype evaluation, 78/182 (42.9%) patients were homozygous wild-type (Thr/Thr), 83/182 (45.6%) heterozygous (Thr/Ala), and 21/182 (11.5%) rare homozygous (Ala/Ala). Age at the time of the first evaluation in our Unit was significantly lower in patients with DIO2 p.Thr92Ala. No significant association was observed between DIO2 p.Thr92Ala and BMI, excess weight, waist circumference, Homa Index. The prevalence of comorbidities was not associated with allele distribution except for hypertension that was more frequent in wild-type patients (p = 0.03). After bariatric surgery, excess weight loss (EWL) % and remission from comorbidities occurred without differences according to genotypes. DIO2 p.Thr92Ala does not affect the severity of obesity and its complications, but it seems to determine an earlier onset of morbid obesity. The presence of polymorphism seems not to impact on the response to bariatric surgery, both in terms of weight loss and remission of comorbidities.

RESUMO

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.

RESUMO

OBJECTIVE: This study aimed to analyze 11 single nucleotide polymorphisms (SNPs) belonging to 9 genes involved in metabolic pathways (BDNF rs6265; PNPLA3 rs2294918 and rs2076212; CIDEA rs11545881; NTRK2 rs2289658; ALOX12 rs1126667; ALOX12B rs2304908; LEPR rs1137101; CPT1B rs470117 and rs8142477; rs2305507 CPT1A) in obese patients and controls. METHODS: Polymorphisms were analyzed in 300 severe obese patients undergoing bariatric surgery (body mass index >30 kg/m2) and 404 control subjects in order to evaluate their association with obesity and clinical variables. RESULTS: Our findings showed significant differences for the allelic distributions of CPT1B rs470117 and LEPR rs11371010 in obese subjects compared to controls. The BDNF rs6265 correlates with obesity only when associated with the other two SNPs. In particular, for CPT1B rs470117 and LEPR rs1137101, the rare allele was associated with a reduced risk of developing the obese phenotype, whereas the simultaneous presence of the common C allele for rs470117 and A allele for rs1137101 was more frequent in obese patients (p = 0.002, OR = 1.417). A significant association between CPT1B rs470117 and steatosis was found. Moreover, we observed that by associating the rare allele T of the BDNF rs6265 with the most common alleles of the SNPs CPT1B rs470117 and LEPR rs1137101, the combination of T-C-A alleles was associated with a higher risk of developing an obese phenotype (p = 0.001, OR = 1.6679). CONCLUSIONS: Our results suggest that SNPs CPT1B rs470117 and LEPR rs1137101 taken individually and in association with BDNF rs6265 may be involved in an increased risk of developing obese phenotype in an Italian cohort.

RESUMO

BACKGROUND: Two of the most common bariatric procedures performed worldwide are Roux-en-Y gastric bypass (RYGB) and one anastomosis gastric bypass (OAGB). Comparative data regarding nutritional status are lacking and no previous study focus on malnutrition according to a validated score. METHODS: Retrospective data from a single institution were reviewed. Anthropometric variables and nutritional data were assessed. The primary aim was to analyze and compare the nutritional status before and 3 years after RYGB vs OAGB using the controlling nutritional status (CONUT) score. The incidence of micronutrient deficiency and the remission of comorbidities in each group were defined as secondary outcomes. RESULTS: Fifty-seven patients in each arm were enrolled. A 3-year mild malnutrition (CONUT score 2-3) was found in 38% and 37.05% in the RYGB and OAGB groups, respectively (p > 0.05). In terms of percentage of total weight loss (%TWL) and percentage of adjustable weight loss (%AWL), no differences were found between OAGB and RYGB groups. OAGB and RYGB patients had similar vitamin deficiencies. Anemia, hypoproteinemia, hypoalbuminemia, and hypocalcemia were comparable between groups. At 3-year follow-up, total protein and albumin values were similar between arms while prealbumin deficit was more frequent after OAGB than after RYGB. The rate of type 2 diabetes (87.5% in OAGB and 92% in RYGB), arterial hypertension (51.6% in OAGB and 58.3% in RYGB), and dyslipidemia (69.7% in OAGB and 78.6% in RYGB) remission was not significantly different between the two groups. CONCLUSIONS: Postoperative CONUT score, micronutrient deficiency, comorbidity remission, and improvement of anthropometric parameters 3 years postoperatively were comparable between RYGB and OAGB groups.

RESUMO

INTRODUCTION: Visceral adipose tissue has been linked with cardiovascular events. Visceral adiposity index (VAI) is a routinely applicable tool for evaluation of visceral adipose dysfunction and linked to 10 year-cardiovascular risk. No previous studies have evaluated the changes over time of the VAI in patients who underwent different types of bariatric surgery. MATERIALS AND METHODS: We reviewed data of 42 patients who underwent laparoscopic sleeve gastrectomy (LSG) and 61 patients who underwent laparoscopic Roux-en-Y gastric bypass (LRYGB). VAI, lipid profile, and several anthropometric variables were measured before and after 5 years following surgery. RESULTS: During the studied time period, the BMI was similar between LSG and LRYGB patients (34.1 vs 31.6; p = 0.191), but the percentage of total weight loss (%TWL) for LRYGB was significantly higher than LSG (31.3% vs 23.0%; p < 0.001). LRYGB patients had a significant improvement of all lipid parameters evaluated over time, while LSG patients experienced only a reduction in triglycerides (TG) levels and an increase in HDL cholesterol (HDL-C). VAI values were similar in the two groups at baseline as well at the last follow-up point (5-year VAI, LSG: 0.93, RYGB: 0.93; p = 0.951). At multivariate regression analysis, 5-year-%TWL was the only independent predictor of a greater amount of VAI reduction over time. CONCLUSION: Bariatric surgery, independent of the type of surgical procedure, decreases the cardiovascular disease (CVD) risks due to weight loss and improvement of lipid parameters. VAI could be a useful tool to better identify eligible patients for bariatric surgery and to determine the success of surgery.

RESUMO

Objective: Liraglutide is a glucagon-like peptide 1 receptor agonist which acts through peripheral and central receptor pathways affecting food intake. Preliminary identification of responder patients represents a crucial point to reduce an inappropriate exposure to the drug and the health expenditure. The primary endpoint of our study was to identify predictors of liraglutide efficacy in the short term follow-up. The secondary endpoint was to evaluate the treatment efficacy stratified by the underlying psychiatric disorder. Methods: We evaluated a cohort of 100 patients (77 females, 23 males, mean body mass index 38.6 ± 3.2 kg/m2) who were evaluated at baseline, and after 1, 3, and 6 months of treatment. Liraglutide efficacy was defined by a weight loss ≥5% of initial weight. Sociodemographic/metabolic parameters, food intake, smoking habit, and physical activity were correlated with liraglutide efficacy. Results: There was a significant weight loss after 1 month of therapy, as well as after 3 and 6 months when compared to the baseline (P<.0001; 27%, 45%, and 57% of patients showed a weight loss ≥5%, respectively). No difference was found in weight loss between the 3 groups of patients (with binge eating, with/without psychiatric disorders). The weight loss at 1 month was the only predictor of a positive response to the treatment. Conclusion: Our results confirm the efficacy of liraglutide even at a lower dose than conventional. The early response to the drug seems to be a good predictor of long-term efficacy and it might be useful in clinical practice to identify patients in whom liraglutide may induce a significant weight loss.

RESUMO

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.

RESUMO

Basal rates of autophagy can be markedly accelerated by environmental stresses. Recently, autophagy has been involved in cancer-induced muscle wasting. Aim of this study has been to evaluate if autophagy is induced in the skeletal muscle of cancer patients. The expression (mRNA and protein) of autophagic markers has been evaluated in intraoperative muscle biopsies. Beclin-1 protein levels were increased in cachectic cancer patients, suggesting autophagy induction. LC3B-I protein levels were not significantly modified. LC3B-II protein levels were significantly increased in cachectic cancer patients suggesting either increased autophagosome formation or reduced autophagosome turnover. Conversely, p62 protein levels were increased in cachectic and non-cachectic cancer patients, suggesting impaired autophagosome clearance. As for mitophagy, both Bnip3 and Nix/Bnip3L show a trend to increase in cachectic patients. In the same patients, Parkin levels significantly increased, while PINK1 was unchanged. At gene level, Beclin-1, p-62, BNIP3, NIX/BNIP3L and TFEB mRNAs were not significantly modulated, while LC3B and PINK1 mRNA levels were increased and decreased, respectively, in cachectic cancer patients. Autophagy is induced in the skeletal muscle of cachectic cancer patients, although autophagosome clearance appears to be impaired. Further studies should evaluate whether modulation of autophagy could represent a relevant therapeutic strategy in cancer cachexia.

RESUMO

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is a worldwide surgical procedure for morbid obesity. However patients selection is still anecdotal. The aim of this study is to analyse clinical and anthropometric parameters correlated with LSG and to check the validity of this procedure for different categories of obese patients. METHODS: Two-hundred one consecutive patients were submitted to LSG as a primary bariatric procedure between 2008 and 2014. One year follow-up was completed in 159 patients. Smaller groups of patients completed 2 and 3 years follow-up (78, 46 patients respectively). Median preoperative body mass index (BMI) was 45.4 kg/m2 (range: 34.8-73.8); 135 patients (80%) had one or more comorbidities. Potential correlations between age, gender, preoperative BMI, preoperative excess weight, early excess weight loss (EWL) and 1 and 3 year-EWL were investigated. RESULTS: All procedures were regularly completed with laparoscopic approach without conversion to laparotomy. Postoperative complications occurred in six patients (3.7%); no postoperative mortality was observed. Median one-year BMI and EWL were 32.8 kg/m2 and 55.34%, respectively. Three year-EWL was significantly influenced by age, and early EWL. A complete normalization of glycemic levels after the three-year follow-up was also observed in high percentage of diabetic patients. In patients with preoperative BMI>50 kg/m2 we observed most failure cases in terms of EWL and the worst metabolic results. CONCLUSIONS: Our experience indicates that LSG is a safe procedure with satisfactory three-year late weight loss in patients with preoperative BMI <50 kg/m2. Promising results, in terms of improvements of comorbidities, were also observed. These results make LSG one of the most attractive first stage surgical procedure for morbid obesity.

RESUMO

INTRODUCTION: Desmoid tumors are defined as a rare fibroblastic proliferative disease and may occur in any musculoaponeurotic or fascial tissue . CASE REPORT: A 54-year-old man with FAP referred to our institution presenting fever and abdominal pain. Four years before a prophylactic colectomy with ileal-rectal anastomosis was done. Three years later a wide intraabdominal mass with desmoid characteristics was detected. In spite of therapy with tamoxifene the RM control showed an increase of mass dimension. Few days later the patient arrived in our istitute with fever and abdominal pain. Medical therapy didn't improve clinical symptoms and the patient underwent surgery. DISCUSSION: Desmoid tumors are benign tumors, but not a benign disease. Most of these tumors occur sporadically, but about 5% arise in association with familial adenomatous polyposis. Intra-abdominal desmoid tumors remain asymptomatic until their growth and infiltration causes visceral compression. They can cause serious complications and treatment is often unsuccessful. Aggressive fibromatosis treatment should be evaluated and managed by a multidisciplinary team with expertise and experience in sarcoma, prior to initiation of therapy. In FAP, surgery has been recommended for abdominal wall tumors but there are only few indications for intra-abdominal disease like pain, bowel obstruction and desmoids perforation.

RESUMO

BACKGROUND: Telomere shortening is physiologically associated with ageing but it may be influenced by oxidative stress and chronic inflammation, linked to obesity. Thus, obesity might represent an additional cause of telomere attrition. We aim to study relative telomere length (RTL) in obese subjects with and without metabolic syndrome and to assess the effect of weight loss induced by bariatric surgery. METHODS: We evaluated RTL in 107 obese subjects (62 with metabolic syndrome and 45 without metabolic syndrome), compared to 130 age-matched non-obese subjects. We also measured RTL in a subgroup of 93 obese patients prior to and 3, 6, 9 and 12 months after surgery. RESULTS: RTL of obese subjects was significantly shorter (p<0.0001) than non-obese subjects but without differences between patients with and without metabolic syndrome (p=0.19). RTL was significantly shorter than baseline at 3, 6, 9 and 12 months after bariatric surgery. CONCLUSIONS: These results confirm that obese subjects have shorter telomeres compared to non-obese subjects, but RTL is not influenced by the presence of metabolic syndrome. RTL shows an additional attrition during the immediate post-operative period, probably due to a catabolic state.

RESUMO

The number of short-stay surgery procedures has progressively increased since the concept of short-stay surgery was first introduced. Initially this type of surgery was reserved for patients undergoing inguinal hernia repair, proctological surgery, and various minor procedures. Careful patient selection makes it possible to apply one-day surgery to other surgical specialties including breast cancer surgery. Reducing the length of hospital stay lowers health care costs, and shortens waiting lists. The most important benefits for patients are a more rapid return to work and positive psychological effects. Exclusion criteria for one-day surgery are the lack of home care, excessive distance from place of treatment and the presence of any concomitant pathology that is a contraindication to this type of surgery. We report our experience in oncological surgery of the breast in one-day surgery.

RESUMO

INTRODUCTION: Intussusception in adults is an infrequent cause of intestinal occlusion that is usually due to neoplasm lesions. The unspecific nature of the clinical presentation often delays diagnosis. It is most commonly emergency explorative laparotomy which clarifies the etiology of the occlusion. The authors report a case of intestinal occlusion caused by ileocecal-colonic invagination with a small cecal adenocarcinoma as lead point, in a 74-year-old woman. CASE REPORT: A 74-year-old woman came to the Emergency Department, complaining of crampy pain in the mid- and lower abdomen. An abdominal ultrasound revealed a "pseudokidney sign" apparently involving the cecum. Because there were no clear signs of occlusion, the patient was dicharged on the same day. Three days later, upon admission, the patient complained of episodes of abdominal pain with intervals of moderate well-being, associated with nausea, vomiting and an inability to pass stool (but not gas) for 36 hours. On clinical examination her abdomen was distended and tender on palpation in all quadrants, especially in the right iliac fossa where a large mass could be felt. Standard abdominal x-Ray documented gaseous distension of some loops of the jejunum-ileum with some air-fluid level. The patient underwent an abdominal CT scan which showed advanced intussusception that appeared to be ileocolic and multiple enlarged lymphnodes were found in the invaginated mesentery at the base of which there appears to be a thickening of the intestinal wall that is probably neoplastic in nature. The patient underwent explorative laparotomy. Ileocecal-colonic intussusception caused by a cecal growth 5 cm in diameter was found on examination of the surgical specimen. Histology showed that the cause of the large swelling of the ascending colon was a vegetating ulcerated adenocarcinoma (medium grade differentiation: G2), measuring 6.5x 4.0 cm, arising from a tubulovillous adenoma infiltrating the submucosa. CONCLUSIONS: Most cases of intussusception are caused by structural lesions, a large percentage of which are malignant, especially in the colon. In our patient the lead point was a small cecal polyp which, together with the last loop of the ileum and the ileocecal valve, was pulled into the ascending colon. Although most cases of intussusception in adults are diagnosed at the operating table, noninvasive diagnostic tools like ultrasonography and CT scanning are very useful. Treatment in adults is usually surgical and involves en bloc resection of the lesion. Manual reduction of the intussusception is not advisable because of the risk of dissemination if the lead point is malignant. KEY WORDS: Cecal adenocarcinoma, Itestinal resection, Intussusception in adults.

RESUMO

The recognition of undifferentiated forms of endocrine tumors in the extrapulmonary sites is considered as extremely infequent. Immunohistochemical patterns of this tumor are similar to small cell neuroendocrine cancer of the lung and as the pulmonary one, it is more aggressive than carcinoma without neuroendocrine differentiation. We report a case of a 68 years old woman with a primary small cell carcinoma of the breast gland presented as a palpable and mobile 2 cm mass, located in the upper outer quadrant of her right breast. It was treated with surgery and the diagnosis was made after surgical treatment, thanks to the immunohistochemical studies of tissue.

RESUMO

Transanal haemorroidal dearterialisation (THD) is a nonexcisional surgical technique for the treatment of piles, consisting in the ligation of the distal branches of the superior rectal artery, resulting in a reduction of blood flow and decongestion of the haemorroidal plexus. THD for 2 degrees and 3 degrees degree haemorroids is highly effective and painless. There are few complications and the technique can be performed as a day case.
