RESUMO

BACKGROUND: Little is known about obesity surgery in young and adolescent patients. The aim of this study is to evaluate results of laparoscopic adjustable gastric banding in obese teenagers. METHODS: Patients < or = 19 years old selected from the database of the Italian Collaborative Study Group for Lap-Band were analyzed according to mortality, comorbidities, laparotomic conversion, intra- and postoperative complications, body mass index (BMI), and % excess weight loss (EWL) at different times of follow-up. Data were expressed as mean +/- SD. RESULTS: Fifty-eight (1.5%) of 3813 patients who underwent operation with the Lap-Band System were < or = 19 years old: 47F/11M; mean age, 17.96 +/- 0.99 years (range, 15-19); mean BMI, 46.1 +/- 6.31 Kg/m2 (range, 34.9 - 69.25); mean % excess weight, 86.4 +/- 27.1 (range, 34 - 226.53). Sixteen (27.5%) of the 58 patients were superobese (BMI > or = 50). In 27/58 (46.5%) patients, 1 or more comorbidities were diagnosed. Mortality was absent. Laparotomic conversion was necessary in 1 patient with gastric perforation on the anterior wall. Overall postoperative complications occurred in 6/58 (10.3%). The band was removed in 6/58 (10.3%) patients for gastric erosion (3 patients), psychologic, intolerance (2 patients), and in the remaining patient was converted 2 years after surgery (BMI 31) to gastric bypass or gastric pouch dilatation. Patient follow-up at 1, 3, 5, and 7 years was 48/52 (92.3%), 37/42 (88.1%), 25/33 (75.7%), and 10/10, respectively. At these times, mean BMI was 35.9 +/- 8.4, 37.8 +/- 11.27, 34.9 +/- 12.2, and 29.7 +/- 5.2 Kg/m2. Mean %EWL at the same time was 45.6 +/- 29.6, 39.7 +/- 29.8, 43.7 +/- 38.1, and 55.6 +/- 29.2. Five/25 (20%) patients had < or = 25% EWL at 5 years follow-up, while none of the 10 patients subject to follow-up at 7 years had < or = 25% EWL. CONCLUSIONS: Lap-Band System is an interesting option for teenagers suffering obesity and its related comorbidities, which deserves further investigation.

RESUMO

Although bariatric surgery has proven to be the most effective treatment for morbid obesity, most surgical techniques do have failures. In an effort to improve the reliability, several surgeons started to use a combination of a laparoscopic gastric bypass with an adjustable gastric band. Because of concerns regarding a possible negative outcome, an expert meeting was organized to evaluate the current situation and future application. In total, 104 operations were reported,with several technical variations. The overall complication rate was acceptable, but the percentage of the band erosions was 6.7%, which is too high. The potential advantages (adjustability, maintained access to the stomach and biliary tree, and reversibility) do not compensate for this complication rate. Based on the results and the opinion of the surgeons experienced in this technique, it is concluded that the combination of gastric bypass with an adjustable gastric band to form the pouch is not recommended.

RESUMO

BACKGROUND: The Lap-Band System is the most common bariatric operation world-wide. Current selection criteria do not include patients with BMI < or = 35. We report the Italian multicentre experience with BMI < or = 35 kg/m(2) over the last 5 years. PATIENTS AND METHODS: Data were obtained from 27 centres involved in the Italian Collaborative Study Group for Lap-Band System. Detailed information was collected on a specially created electronic data sheet (MS Access 2000) on patients operated in Italy since January 1996. Items regarding patients with BMI < or = 35 were selected. Data were expressed as mean +/- SD except as otherwise indicated. RESULTS: 225 (6.8%) out of 3,319 Lap-Band patients were recruited from the data-base. 15 patients, previously submitted to another bariatric procedure (BIB =14; VBG= 1) were excluded. 210 patients were eligible for study (34M/176F, mean age 38.19+/-11.8, range 17-66 years, mean BMI 33.9+/-1.1, range 25.1-35 kg/m(2), mean excess weight 29.5+/-7.1, range 8-41). 199 comorbidities were diagnosed preoperatively in 55/210 patients (26.2%). 1 patient (0.4%) (35 F) died 20 months postoperatively from sepsis following perforation of dilated gastric pouch. There were no conversions to laparotomy. Postoperative complications presented in 17/210 patients (8.1%). Follow-up was obtained at 6, 12, 24, 36, 48 and 60 months. At these time periods, mean BMI was 31.1+/-2.15, 29.7+/-2.19, 28.7+/-3.8, 26.7+/-4.3, 27.9+/-3.2, and 28.2+/-0.9 kg/m(2) respectively. Co-morbidities completely resolved 1 year postoperatively in 49/55 patients (89.1%). At 60 months follow-up, only 1 patient (0.4%) has a BMI >30. CONCLUSIONS: Although surgical indications for BMI < or = 35 remain questionable, the Lap-Band in this study demonstrated that all but 1 patient achieved normal weight, and most lost their co-morbidities with a very low mortality rate.

RESUMO

BACKGROUND: Laparoscopic of the LAP-BAND System placement stage of obesity is a safe operation, but its indication in terms of stage of obesity is controversial. The aim of this study was to evaluate the 5 years stage of obesity results for weight loss in patients with varying preoperative ranges of body mass index (BMI). METHODS: Data were obtained from the Italian Collaborative Study Group for LAP-BAND System (GILB) registry. Detailed information was collected on a specifically created database (MS Access 2000) for patients operated on in Italy from January 1996 to 2003. Patients operated on between January 1996 and December 1997 were allocated to four groups according to preoperative BMI range: 30-39.9 kg/m(2) (group A), 40-49.9 kg/m(2) (group B), 50-59.9 kg/m(2) (group C), and =60 kg/m(2) (group D) percent estimated weight loss respectively. Postoperative complications, mortality, BMI, BMI loss, and (%EWL) were considered in each group. Data are expressed as mean +/- SD, except as otherwise indicated. Statistical analysis was done by means of Fisher's exact test, and p < 0.05 was considered significant. RESULTS: After 5 years from LAP-BAND System surgery, 573 of 3,562 patients were eligible for the study. One hundred fifty-five of 573 (27.0%) were lost to follow-up, 24 of 418 (5.7%) underwent band removal due to complications (gastric pouch dilation, band erosion), eight of 418 (1.9%) were converted to other bariatric procedures, five of 418 (1.2%) died of causes not related to the operation or the band, and 381 of 573 (66.5%) were available for follow-up. Based on 96, 214, 64, and seven patients their preoperative BMI, Were allocated to groups A, B, C, and D, respectively. At time of follow-up mean BMI was 27.5 +/- 5.2 in group A, 31.6 +/- 4.7 in group B, 37.6 +/- 17.3 in group C, and 41.4 +/- 6.9 kg/m(2) in group D. Mean BMI loss was 9.8 +/- 5.4, 12.9 +/- 5.2, 15.8 +/- 8.1, and 23.2 +/- 4.9 kg/m(2), respectively, in groups A, B, C, and D. Mean %EWL at the same time was 54.6 +/- 32.3 in group A, 54.1 +/- 17.2 in group B, 51.6 +/- 35 in group C, and 59.l +/- 17.1 in group D. CONCLUSION: Initial BMI in this series did not correlate with %EWL 5 years after the operation. In fact %EWL was almost the same in each group, independent of preoperative weight. Initial BMI was an accurate indicator of the results obtained 5 years after LAP-BAND in group C (50-59.9 kg/m(2)) and D (=60 kg/m(2)) patients, who remained morbidly obese despite their %EWL.

RESUMO

BACKGROUND: The Lap Band system procedure is currently the most common bariatric surgical procedure worldwide. This is an interim report of the experience of the 27 Italian centers participating in the national collaborative study group for Lap Band (GILB). METHODS: An electronic database was specifically created. It was mailed and e-mailed to all of the surgeons now performing the laparoscopic gastric banding operation in Italy. RESULTS: Beginning in January 1996, 1893 patients were recruited for the study. There were 1534 women and 359 men with a mean body mass index (BMI) of (range 30.4-83.6) and a mean age of 37.8 +/- 10.9 years (range; 17-74). The mortality rate has been 0.53% (n = 10), mainly due to cardiovascular complications (myocardial infarction, pulmonary embolism). The laparotomic conversion rate has been 3.1% (59/1893) and was higher in superobese patients (BMI>50) than in to morbidly obese patients (BMI <50) (p <0.05). Postoperative complications occurred in 193 patients (10.2%), including tube port failure (n = 79; 40.9%), gastric pouch dilation (GPD) (n = 93; 48.9%), and gastric erosion (n = 21, 10.8%). Most GPD (65.5%) occurred during the first 50 patients treated at each center. The incidence of GPD decreased as the surgeons acquired more experience. Surgery for complications was often performed by laparoscopic access, rarely via laparotomy. No death was recorded as a consequence of surgery to treat complications. Weight loss has been evaluated at the following intervals: 6, 12, 24, 36, 48, 60, and 72 months, with BMI 37.9, 33.7, 34.8, 34.1, 32.7, 34.8, and 32. CONCLUSIONS: The Lap Band system procedure has a very low mortality rate and a low morbidity rate and it yields satisfactory weight loss. Surgery for complications can be performed safely via laparoscopic access.

RESUMO

BACKGROUND: Laparoscopic adjustable gastric banding (LAGB) is the most common bariatric operation. This study is a retrospective analysis of the multicenter Italian experience in patients with BMI > 50 over the last 4 years. METHODS: An electronic data sheet made for LAGB-operated patients since January 1996, was mailed and e-mailed to all surgeons involved in this kind of procedure in Italy. Items regarding patients with BMI > 50 were selected. Analysis used Fisher's exact test and logarithmic regression analysis (P < 0.05 significant). Data were expressed as mean +/- SD. RESULTS: 239 patients (13.3%), out of 1,797 Lap-Band operated patients entered the study (179F / 60M), with mean age 37.6 +/- 11.3 years (19-69) and mean BMI 54.6 +/- 4.8 (50.1-83.6). Laparotomic conversion rate was 5.4% (44/239). Postoperative complications occurred in 24 / 239 patients (9.0%). Follow-up was obtained in 218 / 218, 198 / 198, 121 /147, 75 / 93, 30 / 38 LAGB patients at 6,12, 24, 36, and 48 months respectively. At these time periods, mean BMI was 46.7, 43.9, 42.2, 41.9, and 39.3 kg/m2. At the same intervals, mean %EWL was 24.1, 34.1, 38.8, 38.9, and 52.9%. The number of patients with < 25% EWL at 12, 24, 36, and 48 months follow-up were 34, 10, 4, and 0. Serious co-morbidities (189 in 124 of 239, 57%) had completely resolved 1 year postoperatively in 74 / 124 of the patients (59.6%). CONCLUSION: Although super-obese patients following the LAGB remain obese with BMI > 35, in the short-term most lose their co-morbidities, with a very low morbidity and mortality rate.

RESUMO

BACKGROUND: An increasing number of surgeons with different levels of experience with laparoscopic surgery and open obesity surgery have started to perform laparoscopic implantation of the Lap-Band. METHODS: An electronic patient data sheet was created and was mailed and e-mailed to all surgeons performing laparoscopic adjustable silicone gastric banding (LASGB) in Italy. Patients were recruited since January 1996. Data on 1,265 Lap-Band System operated patients (258 M/1,007 F; mean BMI 44.1, range 27.0-78.1; mean age 38, range 17-74 years) were collected from 23 surgeons performing this operation. RESULTS: Intra-operative mortality was absent. Post-operative mortality was 0.55% (7 patients) for causes not specifically related to LASGB implantation. The laparotomic conversion rate was 1.7% (22 patients). LASGB related complications occurred in 143 patients (11.3%). Pouch dilatation was diagnosed in 65 (5.2%), and 28 (2.2%) of these underwent re-operation. Band erosion was observed in 24 patients (1.9%). Port or connecting tube-port complications occurred in 54 patients (4.2%), 12 of whom required revision under general anesthesia. Follow-up was obtained at 6, 12, 18, 24, 36 and 48 months, and mean BMI was respectively 38.4, 35.1, 33.1, 30.2, 32.1 and 31.5. The percentage of patients observed at each follow-up was > 60%. There was no intra-operative mortality and no complication-related mortality, with acceptable weight loss. CONCLUSION: The LASGB operation is safe and effective, and deserves wider use for treatment of morbid obesity.

RESUMO

The authors report an observed case and re-examine the incidence of this defect; they underline the possibility of the diagnosis during the fetal age and the association with one o more defects, sometimes incompatible with the life; in the adult, on the contrary, may be evidence of an associated litiasic pathology of the ++epato-choledocus or of the stenosis of the oddian sphincter. On the base of the diagnostic previous experiences, they elaborate the proposal of an algorythm and underline the utility of a laparoscopic diagnosis either in the pre-operative doubious cases or in the intra-operative diagnosed cases.

RESUMO

We have previously shown that a short course of recombinant interferon-alpha-2b (rIFN-alpha-2b) (3 million units day for 5 days) for patients with primary gynaecologic malignancies was able to increase the circulating levels of a newly discovered tumour associated antigen, termed 90K. In this study, we have investigated the effects of the same modality of administration of rIFN-alpha-2b in 62 patients with breast and colorectal cancer whose primary tumour was surgically removed 1 month before and who were without evidence of disease (NED) at the time of the study. A significant increase of 90K serum concentration was already observed 24 h after the first r-IFN-alpha-2b injection and persisted throughout the investigational period. The increase was more pronounced in patients with a basal 90K-negative than a 90K-positive assay. Of 54 patients who started the test with a 90K negative assay, 17 (31%) shifted to a positive assay after rIFN-alpha-2b. Twenty-eight of 62 (45%) patients exhibited a 90K value above the mean increment of the whole population. The serum levels of CEA, CA-15-3, CA 19-9, and alpha-fetoprotein measured in the same serum samples were not modified. After 2 years of follow-up, ten patients relapsed. Six of them showed a 90K increase above the mean increment of the whole population. As with ovarian cancer, the increase of 90K following r-IFN-alpha-2b administration might be of importance for the early detection of disease recurrence in clinically NED breast and colon cancer patients.

RESUMO

Pathogenesis, morphology and different associated abnormalities in the so-called Poland syndrome are considered. The surgical treatment adopted in the case recently observed is discussed. In most cases an isolated muscular and breast hypoplasia or aplasia is present so that surgery has the only intent to solve the esthetic problem.

RESUMO

Monoclonal antibodies (MAbs) COL-4 and COL-12, to the carcinoembryonic antigen (CEA), and B72.3, CC-49, CC-83, to the tumor-associated glycoprotein 72 (TAG-72), were used to study the expression of distinct epitopes of the two molecules in 71 cases of lung carcinoma of differing histotype. These MAbs reacted with the majority of adenocarcinomas by immunoperoxidase on tissue sections, but demonstrated a more restricted reactivity with squamous carcinomas. MAb CC-49 detected the highest percentages of adenocarcinoma cells while the B72.3 epitope was expressed more in squamous carcinoma cells. No significant reactivity with any of these MAbs was observed in small cell carcinomas. The expression of the CEA and TAG-72 epitopes in non-small cell lung cancers was highly heterogeneous: a distinct epitopes in non-small cell lung cancers was highly heterogeneous: a distinct epitope could be expressed by the majority of cells, whereas another of the same antigenic molecule was either poorly or not expressed. In adenocarcinomas, mixtures of anti-CEA, anti-TAG-72, and anti-(TAG-72 plus CEA) MAbs resulted in additive reactivity with an increase of the immunopositive tumors and of the percentages of immunostained cells. This was particularly evident for the anti-(TAG-72 plus CEA) mixture. In squamous cell carcinomas the increase was modest and was mainly related to anti-TAG-72 reactivity. These studies suggest variability in the antigenic structure of tumor-associated antigens expressed by carcinomas and indicate that anti-(TAG-72 plus CEA) mixtures may represent an immunological adjunct for clinical application in adenocarcinoma patients. On the other hand, TAG-72 should be considered a better target antigen, as compared to CEA, in the detection of squamous cell carcinomas.

RESUMO

One major problem in primary breast cancer is the identification of new parameters able to select patients at high risk of recurrence. Our study was aimed at detecting mammary tumor cells in the bone marrow of breast cancer patients using a single bone marrow sampling and the monoclonal antibody AB/3. This antibody recognizes a membrane carbohydrate epitope present in human breast cancer cells but not in normal tissues. Only 2 out of 45 breast cancer patients were found to have a bone marrow positive AB/3 staining reaction. Our data confirm and extend previous reports that single bone marrow sampling coupled with immunocytochemistry is not sensitive enough to be used as a routine procedure to acquire prognostic information in breast cancer.

RESUMO

A group of 78 patients with gynecomastia was observed between 1974-1987. Idiopathic gynecomastia was referred in 33 cases, cirrhosis in 31 cases, prostatic hypertrophy in 2 cases, while in 12 cases gynecomastia was induced by drugs. All patients with idiopathic form and 11 patients with secondary form were surgically treated by mastectomy (20 bilaterally and 24 unilaterally). The authors emphasize that, in this pathology, is much more important restoring the masculine feature of thorax without esthetic damage than removing the hypertrophic gland.

RESUMO

Starting from one case of chylous ascites of their own observation, the authors attempt an etiological classification of this clinical entity, taking into account pertinent published material and the fact that in many instances chylous ascites is nothing more than a symptom. The authors then proceeds to a critical review of diagnostic and therapeutical resources; in that respect, they stress the extreme difficulties often encountered both in diagnosing the condition and in trying to correct it.
