A retrospective analysis should compare the two operative approaches, transhiatal or transthoracic resection in patients suffering from adenocarcinoma of the esophagus. Between 1985 and 2002 123 cases were presented with adenocarcinoma of the esophagus, treated in 65% by transhiatal resection including abdominal lymph node dissection and in 35% by the transthoracic approach with standardized extended mediastinal and abdominal lymph node dissection. Hospital mortality was 14% (6/43) after transthoracic resection and 3.8% (3/80) after transhiatal resection (ns). Die number of removed and examined abdominal lymph nodes following transhiatal resection was 14.1 (mean) versus 12.3 (mean) after transthoracic resection (ns). Die number of removed and examined mediastinal lymph nodes by transhiatal resection was 6.3 (mean) versus 19.7(mean) after transthoracic resection (p < 0.001). The median survival after transthoracic approach was 19 months versus 20 months after transhiatal approach (ns). Median survival of curatively resected patients (R0) were in both operative procedures similar (21 months). A more differentiated analysis referred to the UICC stages also demonstrated no differences in the survival between transthoracic and transhiatal resection. With respect to less mortality and less morbidity after transhiatal resection and because of the not detectable prognostic advantage of the transthoracic resection we suggest the transhiatal approach as the treatment of choice in patients with adenocarcinoma of the esophagus.

Unlabelled: Laparoscopic Roux en-Y-Gastric Bypass (RYGB) has been performed in our initial series in 50 patients.

Methods: The results of surgery, technique, including 3-12 months follow-up, are described with 100% follow-up in the first 50 patients. Weight loss, operative morbidity and relief of co-morbidities have been thoroughly studied in a prospective way.

Results: Diabetes mellitus was normalized and gastroesophageal reflux was relieved in all patients. Length of stay, recovery time and cosmetic results are superior to the 'open' technique, and the operative times are comparable.

Conclusion: Laparoscopic RYGB deserves a place in the operative repertoire of bariatric surgeon.

Adjunct diagnostic techniques might help surgeons to accurately analyse the depth of a burn. However, despite all technical innovations an ideal device for such an application has not been established for routine use as yet. OPS imaging implemented into the CYTOSCAN A/R is a new, recently introduced technique which allows to obtain high contrast images of the microcirculation without the necessity for fluorescent dyes. The aim of the study was to validate OPS imaging as a tool to study microcirculation in skin after burn injury. OPS imaging was applied by no-touch technique and capillary blood flow was videotaped. Subsequent measurements of the microcirculation were performed at the identical site of the burn. Quantitative analysis of the microcirculation was performed off-line using CapImage. OPS imaging produces high quality images of the microcirculation in a burn wound. Data is given as the number of perfused capillaries per observation area (functional capillary density; FCD) [n/cm2]. OPS imaging allows for direct in vivo visualization and quantification of the microcirculation in burned skin. Our preliminary results of the use of OPS imaging in assessing the microcirculation in burns appear promising, and we hope that this novel technique will allow to improve the knowledge of the dynamics of the microcirculation in the pathophysiology of thermal injury.

Fractures of the distal end of the femur are rare. Premature partial closure of the physis may occur after metaphyseal fractures. After epiphyseal fractures it has a high incidence of occurrence. The cause of physeal arrest is not known. Stimulation of the physes ends in leg length discrepancy and was seen in 50% of all cases. Spontaneous correction of an axis deviation is possible after antecurvation up to an age of 5 years. But this should be only accepted during therapy of metaphyseal fractures of the distal femur. Side-to-Side deviations remodel in all cases. Aim of therapy in distal epiphyseal fractures should be an anatomical reduction and a definitive retention. Screw osteosynthesis seems to have an advantage.

The effects of pouch reconstruction on long term are dependent not only on the capacity of the pouch, but also on its motility and contractibility. Problems with evacuation of the pouches in the upper and lower abdominal tract may become a major problem in a significant part of the patients. Thus the length of the pouches should be limited to 5 cm at the most in patients with complete rectal resection and to 10-15 cm after gastrectomy. The evacuation profile of the pouches is influenced in addition by the outlet characteristics of the pouch. Finally one should take into consideration that the beneficial effects of pouch reconstruction disappear with time due to adaptation of the bowel after straight reconstruction procedures, while on the other hand the evacuation problems persist.

Early functional outcome after low anterior resection with total mesorectal excision (TME) and colo-anal anastomosis for colorectal carcinoma can be improved by the restoration of the colonic reservoir. This can be achieved by the construction of a colonic J-pouch. The technique is safe and has been refined during the last years. A decrease in stool frequency, urgency, and incontinence rates during the first two postoperative years with an improved quality of life has been observed. Alternative methods with similar functional results are provided by the ileocecal reservoir, the transverse coloplasty pouch or the side-to-end anastomosis. Colonic J-pouch reconstruction should be considered as an superior alternative to straight coloanal anastomosis in patients undergoing anterior resection.

Gynecomastia develops when there is an increase in the ratio of estrogen to androgens. Whereas mild forms of gynecomastia are frequently encountered in the male population, any breast enlargement that is prominent, painful, progressive or of recent onset always requires a careful evaluation, as it may be an important clue to disease elsewhere. Underlying causes are plenty and include drugs, congenital and acquired disorders of androgen and estrogen production, various tumors, renal failure, cirrhosis of the liver, and thyrotoxicosis. Evaluation includes a careful patient's history, physical examination of sexual characteristics and the breast tissue, and measurements of serum LH, FSH, testosterone, estradiol, hCG-beta, TSH and tests of liver and kidney function.

Based on pathological-anatomical findings, early (2 months) and late (2 years) local and distant recurrencies are presented, considering topographic aspects following surgery of primary pulmonary tumours, metastatic pathways and time intervals. Morphological criteria for differentiating two tumours from metastases, systemic recurrencies of the basic disease following early micrometastatic spread, as well as the grading of tumour regression in surgical samples following radio chemotherapy are shown.

Conservative treatment of meatacarpale fracture is recommended if there are no joint displacement, rotation failures, displacement over 30 degrees ad axim and shortening over 5 mm. Operative procedures should be done in open fractures and serial of fractures of metacarpale bones. Early functionally treatment should be done in stable, not displaced fractures. Cast can be used only for a short time in full extended position of fingers and flexion in metacarpo-phalangeal joint in 60-90 degrees. Twin-tapes after reduction of edema allowed free range of motion by fixed rotation. Closed reduction of displaced fractures of fifth metacarpal bone (boxer's fracture) isn't successful. Cases with displacement over 30 degrees may be operatively treated by intramedullary stabilization.
