Ultrasonographic imaging of neoplasms of the cervical esophagus

BACKGROUND/AIMS: We studied the effectiveness of ultrasonography in evaluating the cervical esophagus for the presence of large masses arising from the esophageal wall and consequently, the modifications of the visceral lumen. MATERIALS AND METHODS: The cervical esophagus can be evaluated by ultrasound with longitudinal and axial scans, using the left thyroid lobe as an acoustic window. The cervical esophagus can be visualized from the C5 to D2 vertebrae. From November 1992 to July 1996, 220 patients with esophageal cancer and 120 subjects without esophageal disease (control group) were examined with ultrasonography. Examination of the cervical esophagus was performed with a linear high definition small parts probe with a frequency of 7.5-10 Mhz. RESULTS: In all 31 patients with cancer of the cervical esophagus, ultrasonography of the cervical region showed the presence of an expanding mass from the esophageal wall as well as the modifications in the visceral lumen. The neoplasm of the cervical esophagus was visualized when its diameter exceeded 5 mm. CONCLUSIONS: The experience of the authors shows that, during ultrasound examination of the cervical region, it is possible to accurately evaluate the cervical esophagus, either morphologically or functionally

Bioenterics intragastric balloon : 7 years experience

Background: Since 1998, we adopted in our clinical practice for treatment of obesity and morbid obesity the BioEnterics Intragastric Balloon (BIB\uae): it has the characteristics of an \u201cideal gastric balloon\u201d (Tarpon Springs Workshop, 1987). Methods: Since March 1998, we placed by the endoscopic approach 518 BIB in 480 patients affected by obesity and morbid obesity; 124 male and 356 female, mean age 41.6 years (18-72), mean weight kg 116.9 (67-229), mean BMI 42 kg/m2 (27.3-81.1). All our patients underwent diet of 1000 Kcal/day and treatment with antisecretory drugs. Results: The mean weight lost was 14.69 kg and the mean reduction in BMI was 5.11 kg/m2. Weight lost was greater in male morbidly obese (BMI >40). Weight lost was accompanied by an improvement of the diseases associated with obesity: diabetes, arterial hypertension and sleep apnea. Conclusions: The best indications for BIB were: morbidly obese patients (BMI >40) and super-obese patients (BMI >50) in prepa- ration for bariatric surgery; obese patients with BMI 35-40 with co- morbilities in preparation for bariatric surgery; obese patients with BMI 30-35 with a chronic disease otherwise unresolved; patients with BMI <30 only in a multidisciplinary approach

Prevention of pouch dilatation after laparoscopic adjustable gastric banding

BACKGROUND: The major long-term complication of laparoscopic adjustable gastric banding (LAGB) is dilatation of the gastric pouch, that is reported with a frequency ranging from 1 to 25%, and often requires removal of the band. In addition to the usual recommendations of bariatric surgery centers and dietetic advice to prevent this complication, over the last 4 years we introduced a technical modification of the procedure. METHODS: From Nov 1993 to Dec 2004, 684 morbidly obese patients underwent adjustable gastric banding, 83 patients by open surgery and 601 patients by laparoscopy. The first 323 patients (group A) were operated by the perigastric approach, and 57 patients (group B) were operated by the pars flaccida approach. Since Dec 2000, 304 patients (group C) were operated with a modified pars flaccida technique, which consisted in suturing the gastric lesser curvature below the band with one or two stitches to the right phrenic crus to secure the band in place. RESULTS: In group A, the most important late complication was irreversible dilatation of the gastric pouch, which occurred in 35 patients (10.8%), and required removal of the band in 30 cases and replacement in 5. In group B, there were 3 pouch dilatations (5.2%). In group C, only 4 dilatations occurred (1.31%), which required 3 band removals and 1 band replacement. CONCLUSION: Dilatation of the gastric pouch appears to be dramatically reduced by our minor technical modification of band placement

Ultrasonographic evaluation of the cervical lymph nodes in preoperative staging of esophageal neoplasms

Background: The detection of cervical lymph node metastases plays an important role in staging of patients affected by esophageal cancer to perform the best therapeutic approach.Methods: We report our experience concerning the ultrasound evaluation of the cervical area in 174 patients with esophageal cancer. Ultrasonographic evaluation of the neck can be done with a 7.5- or 10 MHz transducer in all cases, with selective scanning of the lymph node chains of the internal jugular veins and supraclavicular regions. The short-to-long axis ratio (S/L) was a useful way to detect lymph node metastasis. Histopathologic diagnoses were obtained by sonographically guided fine-needle aspiration biopsy.Results: At ultrasound examination, we found 18 (10.3%) patients with metastatic cervical nodes. Of these, 17 (94.4%) had metastatic cervical lymph nodes confirmed by cytology from fine-needle biopsy. Lymph node exceeding 5 mm in long axis and with an S/L over 0.5 showed a higher incidence of metastasis than those with an S/L under 0.5. Our experience shows a high incidence of lymph node metastases in patients with esophageal cancer localized to the thoracic supracarinal tract and in patients with cervical and lower esophageal cancer.Conclusion: In the ultrasound evaluation of nodes, the most useful parameters are size of nodes, heterogeneity of internal echoes, morphology of the margins, and the deformation caused by compressive instrumental manipulation. These criteria, indicated by the Japanese Society for Esophageal Diseases, yield a high sensitivity and diagnostic specificity when the ultrasonographic studies are performe

Il palloncino intragastrico BIB

INTRODUCTION: Since 1998, we adopted in our clinical practice for obesity treatment the new intragastric balloon (BioEnterics Intragastric Balloon, BIB), it has the characteristics of an "ideal gastric balloon" (Workshop Tarpon Springs, 1987). MATERIALS AND METHODS: Since March 1998 we have placed by endoscopic approach 518 BIB in 480 patients affected by first, second and severe morbid obesity; 124 male and 356 female, mean age 41.6 years (18-72), mean weight Kg 116.9 (67-229), mean BMI 42 Kg/m2 (27.34-81.14). All our patients underwent to diet of 1000 Kcal/day and treatment with antisecretory drugs. RESULTS: The mean weight lost was Kg 14.69 and the mean reduction in BMI was 5.11 Kg/m2. Weight loss was greater in male severe obese (BMI > 40). Weight was accompanied by an improvement of the disease associated with obesity, in particular diabetes, hypertension and sleep apnoea. DISCUSSION AND CONCLUSION: The best indication for BIB were: morbidly obese patients (BMI > 40) and super-obese patients (BMI > 50) in preparation for bariatric operation; obese patients with BMI 35-40 with co-morbilities in preparation for bariatric surgery; obese patients with BMI < 30 only in a multidisciplinary approach patients with BMI 30-35 with a chronic disease otherwise unresolved
