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.

PURPOSE: There is little information about the nutritional status of cancer outpatients because the practice of nutritional screening is rarely performed. This study aims to define the pattern of scores of nutritional risk in 1,453 outpatients and factors associated with a high nutrition risk score, to facilitate the identification of such patients by the oncologists. METHODS: We prospectively screened the nutritional status of cancer outpatients according to the NRS-2002 score which combines indicators of malnutrition and of severity of the disease (1-3 points, respectively). A score ≥ 3 indicates "nutritional risk". The association of the nutritional scores with some patient/tumour/therapy-related variables was investigated through univariable and multivariable linear regression models. RESULTS: Thirty-two percent of outpatients were at nutritional risk. Primary tumour site, Eastern Cooperative Oncology Group score and presence of anorexia or fatigue were significantly associated with the nutrition risk score. Depending on the combination of these variables, it was possible to estimate different probabilities of nutritional risk. CONCLUSIONS: The frequency of a relevant nutritional risk was higher than expected considering the favourably selected population. The nutritional risk was associated with common clinical variables which are usually recorded in the charts and could easily alert the oncologist on the need of a further nutritional assessment or a nutritional support.

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.

Radiation proctitis, is a relatively frequent complication resulting from the direct or collateral irradiation of the rectum in radiotherapy treatment for genito-urinary or anorectal malignancies. The main symptoms are diarrhoea, tenesmus, proctorrhagia, anal pain, mucorrhoea and faecal incontinence. The evolution of chronic radiation proctitis requires treatment for related anaemia, anal incontinence and micturition disorders. The approach and type of treatment depend on the severity of the symptoms and on the endoscopic aspect, in relation to the response to previous medical therapy performed. In our experience, endoscopic treatment is the best choice in the presence of ongoing bleeding and the possible development of severe anaemia. The surgical option is mandatory in patients at high risk of sepsis, requiring a faecal diversion constructed using the Hartmann technique. We report two cases, observed during the last two years, one treated with endoscopic bipolar coagulation and the other with a double urinary and faecal diversion.

The latest hepatic surgical strategies enable liver resections to be performed on a larger number of patients, improving the survival rate. Moreover, the contribution of radiological techniques and chemotherapy to surgery has led to the multidisciplinary management of patients suffering from liver metastases, involving surgeons, radiologists and oncologists. If surgical treatment is not considered curative, it is appropriate to advise alternative strategies in order to down-stage the disease and make it resectable.

Rectocele is an organic cause of chronic constipation, with a prevalence ranging from 8.95% to 12% in Europe and United States. Necessarily, the approach for rectocele repair is a surgical operation. Stapled transanal rectal resection (STARR) is safe and effective in the treatment of obstructed defecation syndrome. The authors' experience suggests that the surgical operation needs to be combined to rehabilitation exercises, before and after the surgical treatment, in order to strengthen the muscles of the pelvic pavement. From January 2005 to January 2007, 20 patients with outlet obstruction underwent STARR. Patients were selected for operation based on a strict diagnostic protocol: anamnesis, clinical examination, coloproctological and urogynaecological examinations, defecography, anorectal manometry, transrectal ultrasonography and peritoneal electromyography. The therapeutic protocol consists of 3 parts: phase I: rehabilitation of the pelvic pavement; phase II: surgical operation; III phase: post-surgical rehabilitation of the pelvic pavement; The clinical result was classified into: excellent (6 patients), when all constipation symptoms disappeared, good (11 patients), when patient has 1 or 2 obstructed defecation episodes treated with a laxative, fairly good (2 patients), more than 2 episodes, and poor (1 patient), when surgical operation doesn't improve any of the symptoms. Our results, confirmed by the literature, suggest that Longo's technique should be considered as gold standard for rectocele treatment.

BACKGROUND: Cancer, perforation, and bleeding in the bypassed stomach after Roux-en-Y gastric bypass (RYGB) are rare, but serious, complications that need an early diagnosis. Our goal was to perform gastric bypass such that traditional endoscopic and radiographic study of the gastric remnant would be possible and, at the same time, obtain results in terms of weight loss equivalent to those found after standard RYGB. A previously published study demonstrated that complete occlusion of the gastrogastric outlet was not necessary to lose weight. We have developed an open RYGB-on-vertical banded gastroplasty procedure. METHODS: Since 2002, 289 patients with a mean age of 40.1 +/- 14.8 years, mean body mass index of 51.4 +/- 7.3 kg/m(2), and mean percentage of excess body weight of 107.3% +/- 36.7% underwent RYGB-on-vertical banded gastroplasty as their primary procedure. RESULTS: The follow-up examinations included radiographic and, if necessary, endoscopic studies at 6 and 12 months postoperatively and annually thereafter. Two cases of anastomotic ulcer were detected, one of which involved band erosion. The percentage of excess weight loss was 48.2% +/- 18.8% after 6 months and 59.0% +/-17.7%, 63.3% +/- 13.9%, 66.9% +/- 17.5%, and 70.0% +/- 17.7% after 1, 2, 3, and 4 years, respectively. The weight loss curve was similar to that for standard RYGB. CONCLUSION: The results of our study have shown that RYGB-on-vertical banded gastroplasty is as effective as traditional RYGB, while allowing for traditional radiography of the bypassed stomach in every patient. Endoscopy of the distal stomach and, therefore, the biliary tract, was also possible. These are the fundamental aspects of the procedure.

Urachus' carcinoma represents a rare oncologic disease with an unfavourable prognosis due to the usual delay of correct diagnosis for its anatomical localization. Its surgical treatment varies from radical cystectomy to segmentary resection of the bladder with pelvic lymphadenectomy. We report a case occurred in a ninety years old female, in which the diagnosis was achieved only at laparotomy. The patient was submitted to surgery with the only generic diagnosis of "lower abdominal mass", and treated with segmentary resection.

The Authors examine the feasibility of diagnosing non-functioning gastroentero-pancreatic neuroendocrine tumours preoperatively or intraoperatively, with particular reference to laboratory examinations and octreoscan scintigraphy, which are capable of conditioning the surgical treatment and subsequent follow-up. Of the 4 cases reported here: three presented multiple intestinal localizations, and in only one case the origin of the primitive carcinoma was undefined. The suspicion of a non-functioning neuroendocrine tumour must be considered when yellowish or ochre-coloured intestinal lesions are found intraoperatively. Determination of specific markers and octreoscan scintigraphy must be performed without awaiting histological confirmation. Surgery plays a fundamental role in the debulking of these carcinomas. However, medical therapy with the aid of specific laboratory examinations and octreoscan scintigraphy may improve the long-term survival.

Rectal cancer is characterised by a substantial incidence of recurrences despite radical surgical treatment. The combination of preoperative radio- and chemotherapy has afforded functional and prognostic advantages through the prospect it offers of performing a greater number of conservative operations and the enhanced control of locoregional recurrences it allows. In our institute we treated 27 patients with locally advanced rectal cancer over the period from January 1997 to December 2002. All 27 patients underwent preoperative radiochemotherapy (45 Gy on the pelvis and 5-fluorouracil administered on the first and last 5 days of radiotherapy). The patients were then submitted to surgery consisting in 12 abdomino-perineal resections of the rectum, 14 anterior rectal resections and 1 Hartmann's resection. Tumour regression was complete in 22.22% of cases and minimal in 14.81%; 50% reduction was achieved in 22.22% and 50-80% reduction in 40-70% of cases. The toxicity was 14.91%. The incidence of local failure was 3.7% with a follow-up of 52 months. In this series, preoperative radio-chemotherapy proved to be a powerful means of downstaging the tumours and of controlling local failure.
