Synchronous tumours of the unilateral parotid gland: rare or undetected?
INTRODUCTION: Multiple tumours of the parotid gland with the same histological appearance may occur as synchronous unilateral tumours, but bilaterality has also been reported. Synchronous multiple unilateral parotid tumours with different histology remain rare. METHODS: Between January 1988 and May 2002, a total of 341 patients underwent parotidectomy in our department. Medical charts were reviewed retrospectively for synchronous multiple unilateral tumours. RESULTS: Fourteen patients had two or more tumours within the same specimen. The combinations encountered were two to four adenolymphomas (n=9), adenolymphoma plus pleomorphic adenoma (n=3), adenolymphoma plus MALT lymphoma (n=1), and pleomorphic adenoma plus acinic cell carcinoma (n=1). The outcome was clinical freedom from signs of tumour recurrence in any patient (mean follow-up = 51 months). CONCLUSION: Synchronous multiple unilateral parotid tumours usually include two or more adenolymphomas and might occur more often than previously realized. The possibility of a concomitant carcinoma, and the prevention of recurrent tumours, may warrant a more radical surgical excision of the parotid gland, accurate intraoperative examination of the resected specimen, and routine histological evaluation of the entire specimen. Preoperative radiological investigation may further increase the chances of finding multiple parotid tumours.

Local recurrence of rectal cancer after total mesorectal excision without preoperative radiotherapy.
BACKGROUND: At this moment, it is still debatable whether all patients with mobile rectal cancer who undergo surgical removal of the tumor should be treated with preoperative radiotherapy, since it is likely that only certain patients will benefit from this strategy. In this study, patients with mobile rectal cancer were immediately operated upon and only those with positive nodes or with incomplete resection received adjuvant radiotherapy. AIMS OF THE STUDY: To investigate the local recurrence rate after the use of a selective policy of adjuvant radiotherapy and to determine risk factors for local recurrence. METHODS: In a 5-yr-period, 178 patients with rectal cancer were referred to our institute. A total of 131 patients with mobile rectal cancer were treated with curative intent, which implied a microscopically radical resection and no signs of distant metastasis at operation. A retrospective analysis was undertaken to investigate the incidence of local recurrence in this curative group and to determine risk factors for local recurrence. RESULTS: The postoperative mortality in the curative group was 5.3%. Local recurrences were observed in 6 patients (4.6%) after a median period of 25 mo (range 11-37); two of them also had distant metastases detected at the same time. The highest local recurrence rates were seen in men (5.3%), in distal rectal cancers (6.9%), and in the node-positive group (8.7%). CONCLUSION: A low local recurrence rate can be achieved after total mesorectal excision (TME) without preoperative radiotherapy. Our results suggest using preoperative radiotherapy only for those patients who are at a higher risk for local recurrence. Staging techniques for selection of these patients are at this moments till inappropriate.

Endovascular treatment of traumatic thoracic aortic rupture combined with diaphragmatic rupture--a case report.
The purposes of this report are to describe the immediate repair of a diaphragmatic rupture and subsequent endovascular treatment of a thoracic aortic rupture secondary to blunt chest and abdominal trauma and to discuss the outcome in the light of the trauma scores. A 29-year-old man was injured in a car collision. There were signs of a left diaphragmatic rupture and spleen injury. After urgent laparotomy, the diaphragm was repaired. The spleen appeared uninjured; however, there was a dissection with a transmural tear of the thoracic aorta, which was subsequently treated intraluminally by using a Talent endovascular graft and two AneuRx aortic extension cuffs. The patient fully recovered, and the thoracic endograft showed no evidence of endoleak both 1 month and 1 year after treatment. Fourteen months after the operation, the patient is doing well. Endoluminal techniques can be used successfully in the immediate repair of thoracic aortic injuries, even in the presence of a diaphragmatic rupture. With the introduction of advanced repair modalities, such as endovascular techniques, mortality rates will decrease and may eventually alter injury-scoring systems such as the Injury Severity Score.

Thoracic stent grafts with a distal fenestration for the celiac axis.
Descending thoracic aneurysms can be treated with a stent graft provided that there is sufficient proximal and distal aortic neck length above the celiac axis. One of the options for the treatment of thoracic aneurysms with a too short distal neck is described in this report. For this purpose, a stent graft was constructed with a scallop for the celiac axis. Three cases are presented, and the technical details are described.

Evolution of staples and clips for vascular anastomoses.
Because of the development of less invasive surgical techniques, there is an increasing demand for vascular anastomosing techniques that require less exposure of the operating field. This paper reviews the most important representatives of staples, clips, and other mechanical devices for vascular anastomosing described over the last five decades. This report is organized in three parts: (1) the history of clipping and stapling devices, (2) development of the Vessel Closure System (VCS) clips, and (3) current and potential status of mechanical vascular anastomotic devices. A Medline literature search was conducted and publications on the use of staples and/or clips for the creation of vascular anastomoses identified with extensive cross-referencing. The first literature description of a mechanical vascular stapling device was by Gudov in 1950. This and other reports from the Soviet Union stimulated brisk, competitive development of vascular anastomotic devices in Europe, North America, and Japan. Fasteners included staples, penetrating pin-rings, or toothed stainless steel clips, none of which gained acceptance because of their complexity and inability to facilitate end-to-side anastomoses. A more convenient and less traumatic anastomotic system (VCS Clip applier system) was introduced into clinical practice in 1995. This system differs from staples in that it is non-penetrating. A wide variety of reports have described the advantages, both technical and biological, that clips provide over conventional needle-and-suture, particularly for the construction of vascular access for hemodialysis. A steady evolution of mechanical vascular anastomotic devices has sought to eliminate the technical and biological disadvantages of conventional suturing. Although the conventional hand-sewn, overcast non-absorbable suture remains the "gold" standard, newer techniques such as the non-penetrating arcuate-legged VCS clips are gaining acceptance as a useful addition to the vascular surgeons' armamentarium.
