Lap Band adjustable gastric banding system: the Italian experience with 1863 patients operated on 6 years.

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.

Results of the Italian multicenter study on 239 super-obese patients treated by adjustable gastric banding.

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.

[Breast calcifications with percutaneous vacuum-assisted biopsy diagnosis of malignancy or atypical hyerplasia: correlations with surgical findings]. / Calcificazioni mammarie con diagnosi di malignità o iperplasia atipica su biopsia percutanea vacuum-assisted: correlazioni dopo escissione chirurgica.

Percutaneous, stereotactic, vacuum-assisted biopsy has become a widely used alternative to open surgical biopsy for the initial diagnosis of breast calcifications. We retrospectively assessed the accuracy of the technique in the diagnoses of malignancy and atypical hyperplasia by correlation with the findings of the subsequent surgical excision. We studied 330 consecutive cases of breast calcifications, 216 (65.5%) of which were determined to be benign and 114 (34.5%) to be malignant or atypical at vacuum-assisted biopsy using an 11 gauge instrument. Of the latter 93 were available for comparison with the subsequent surgery, the specific diagnoses as revealed by percutaneous biopsy were as follows: 11 cases of atypical ductal hyperplasia (ADN), 67 cases of ductal carcinoma in situ (DCIS), 6 infiltrating ductal carcinomas (IFDC), 2 cases of atypical lobular hyperplasia and 7 of lobular carcinoma in situ (LCIS). At histological analysis after surgical excision, 3 (27%) of 11 cases previously diagnosed as ADH and 6 (9%) of 67 cases diagnosed as DCIS were shown to actually be higher grade lesions (DCIS/IFDC and IFDC, respectively). Of the 7 lesions diagnosed at vacuum-assisted biopsy as LCIS, surgery and histological analysis showed one infiltrating globular carcinoma and two DCIS. A total of 21 lesions (4 ADH, 14 DCIS, 1 IFDC, 2 LCIS) were completely removed at percutaneous biopsy; the remaining cases were found totally concordant. These data Indicate a substantial accuracy of the percutaneous biopsy: some lesions (particularly those thought to be ADH and DCIS) can be underestimated for sampling error.

Laparoscopic Italian experience with the Lap-Band.

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.

[Papillary carcinoma in thyroglossal duct cyst remnant: review of the literature and presentation of a clinical case]. / Carcinoma papillare in cisti del residuo del dotto tireoglosso: revisione della letteratura e presentazione di un caso clinico.

The authors report a case of papillary carcinoma arising from thyroglossal duct remnant. It was the only case observed in the last 20 years among 9000 thyroidectomies performed. After a survey of Literature, the role of total thyroidectomy combined to Sistrunk's technique is underlined.

Spindle cell and cartilaginous metaplasia in a breast carcinoma with osteoclastlike stromal cells. A difficult fine needle aspiration diagnosis.

The cytologic picture in fine needle aspirates from a unique type of breast tumor, with stromal proliferation of osteoclastlike giant cells, cartilaginous metaplasia and metaplastic spindle-shaped carcinomatous cells, is described. In this case, an erroneous cytologic diagnosis of fat necrosis associated with a rich component of reactive fibroblasts was made. This false-negative report, which was mainly due to lack of an obvious carcinomatous component in the aspirated material, is discussed with emphasis placed on the need to exclude spindle cell metaplasia in a breast carcinoma whose aspirates are characterized by a rich component of spindle-shaped cells.
