Introduction: Intraarterial thrombolysis of acute arterial occlusions in the lower limbs is an established therapeutic procedure. However, its value as a primary treatment is discussed controversially and it is mostly seen as a competing procedure to primary vascular surgical interventions., Methods: From January 2001 to December 2004, we performed a total of 132 intraarterial thrombolysis procedures in 112 patients with acute or subacute ischaemia of the lower limbs. In the majority of the cases, there was an ischaemia of stage I or II a according to Rutherford, a few further cases were in stage II b at the start of treatment. The patients' ages at the time of thrombolysis was 64.7+/-11.3 years (mean value+/-standard deviation, range: 27-91 years). There were 46 female and 86 male patients., Results: The average duration of thrombolysis was 35.2+/-20.8 hours (mean+/-standard deviation, range: 6-142 hours). As median 2 (range: 0-8) angiographic controls were performed. In 100 cases (75.8%), an operation could be avoided by thrombolysis alone or in combination with an supplementary intervention. On the other hand, in 32 cases (24.2%) a subsequent operative therapy including 10 major amputations (7.6%) was necessary. Because of hemorrhagic complications, 15 thrombolysis procedures (11.4%) had to be terminated prematurely but only 2 patients required an inguinal revision. Therapy-related mortality was 0.8% (1 patient)., Conclusion: In the majority of our patients, primary intraarterial thrombolysis was successful and often led to the discovery of the underlying vascular lesion. It can serve both as a therapeutic alternative to a primary vascular surgical intervention and as the foundation further interventional or vascular surgical therapies although this cannot always be predicted for individual cases.

Introduction: Complications of gastroduodenal ulcers such as bleeding and perforation have been afflicted with a mortality of up to 40 % in the past. Altered ulcer manifestation by improvement of medical treatment as well as advances in surgical techniques and intensive care medicine might currently have improved the outcome of these severely ill patients., Patients and Methods: A retrospective analysis of 73 patients with emergency operation for bleeding or perforated gastric (n = 50) and duodenal ulcer (n = 23) between 10/1994 and 7/2001 was performed., Results: The median age was 58 years (17-90 years) with 30 % of patients exceeding the age of 70 years. Eighty-one percent of patients had perforation, 19 % had bleeding. Factors predisposing for gastroduodenal ulcers were present in 88 %. Five percent of gastric perforations were due to gastric malignancies. Diagnosis of perforation was made in 88 % by conventional X-rays, in 12 % of perforations no free abdominal gas was detectable. A local surgical procedure (excision of ulcer and sutures/pyloroplasty) was performed in 64/73 patients (88 %), partial gastroduodenal resection was necessary in 9 patients (12 %). Histologic examination for helicobacter pylori was positive in 30/39 specimens (77 %). In-hospital mortality was 14 %, both for patients with bleeding and perforated ulcers. Surgical complications were 12 %., Discussion: Altered ulcer manifestation, minimized surgical therapy and improved intensive care medicine led to a recent reduction in postoperative mortality of patients suffering from perforated or bleeding gastroduodenal ulcer. A further reduction of this still high mortality might be expected by improvement of surgical training and/or restriction of therapy to a limited number of surgeons.

Over a period of 9 years in 48 patients already operated on for ulcerative colitis secondary surgical interventions had to be planned. 25 patients had an ileostomy (IS), 10 a Kock-pouch (KP), 11 an ileoanal pouch (IAP) and 2 an ileorectal anastomosis (IRA). Whereas in 4 patients only the subjective wish for another procedure with better quality of life predominated, in 44 patients (91.7%) also objective, sometimes multiple indications for reoperation existed. In 37 patients main indications were complications or dysfunctions of the preexisting procedures, combined with the need for further resection of the colitis in 6 of them. Resection of the residual colitis was the main indication in the remaining 7 patients. The aim of the reoperation in all patients was both complete elimination of the eventually persisting colitis and restoration of quality of life in the best way wished or possible. Our of 25 IS 3 remained, 3 were reconstructed, 17 were converted to KP and 2 to IAP. Out of 10 KP one remained and in 9 corrective surgery of the nipple valve was performed. Out of 11 IAP 2 had to be resected with construction of IS, 5 were converted to KP and 4 were corrected. Two IRA were converted to IAP. The rate of early complications was 8.3% (n = 4), lethality was zero. Late complications occurred in 13 cases (27.1%) and were associated ten times with KP. Complications of KP decreased with time to zero due to technical modifications. They could always be corrected restoring function. Since only one KP had to be resected due to severe pouchitis, KP was an important secondary procedure for 31 out of 48 patients also in the long-term course ensuring both complete elimination of colitis and good quality of life owing to voluntary fecal control.

Laparoscopic assisted proctocolectomy with ileoanal pouch is a technical alternative to the conventional open procedure. The aim of this technique are better cosmetics. Mobilisation of the colon is achieved laparoscopically. Rectal resection, J-pouch creation, and pouchanal anastomosis are performed via a Pfannenstiel incision. Laparoscopic assisted proctocolectomy has been performed in five selected patients, three female and two male aged 17 to 36 years. Operative time ranged from 305 to 420 minutes. Intra- and postoperative complications were not encountered. Postoperative hospital stay ranged from 13 to 16 days. On a scale from 1 to 10 the average quality of life was graded 9 and the overall satisfaction level with the results of surgery scored 10. Function was identical to open surgery in not selected patients.

Unlabelled: From Jan. 1993 to Apr. 1997 intestinal resections in Crohn's disease have been performed in 275 patients. 89 patients have been operated on laparoscopic assisted. The following parameters were analyzed: previous laparotomies, extent of resection, steroid medication, conversionrate, complications, operative time and postoperative stay. Endpoints were: conversionrate, complications, reconvalescence and overall satisfaction with the laparoscopic technique., Results: The duration of the disease ranged from 1 to 16 years (x = 6). 47 patients were under steroid medication at the time of surgery. 30 patients had undergone previous laparotomies. In 10 patients the operation had to be converted into open surgery. The following procedures have been performed: ileocaecal resections (45), anastomotic resections (14), small bowel resections (4), hemicolectomies (12), colectomies (9), loopileostomies (4), adhesiolysis (1). Minor complications occurred in 6.7% of patients, major complications in 5.6%. Operative time ranged from 70 to 420 minutes (x = 173.7). The postoperative hospital stay was 13.3 days in the average., Conclusion: The morbidity of 12.3% is not higher than in open surgery. When complications do not occur the patients benefit from early convalescence, better cosmetics and shorter hospital stay.

In a 15 years period surgery of ulcerative colitis expanded from ileostomy (IS) via Kock's pouch (KP) and ileoanal pouch (IAP) to ileorectal anastomosis (IRA). Interactions between availability of methods and frequency of operations are investigated retrospectively in order to establish an optimal primary procedure. With an overall amount of 80 operations the yearly operative frequency raised in correlation to the introduction of continence reconstructive procedures. As a consequence of this fact history of disease was shortened to less than 8 year and global colitis-associated morbidity markedly decreased. For patients readiness to undergo operation Kock's pouch was only important at the beginning (n = 9/11.3%). Most decisive was IAP (n = 49/61.3%) which could be realized last even in an one-stage-procedure with better early results due to improved patients conditions and simplified technical modifications. IRA (n = 7/8.8%) played only a limited role in the last years for selected patients, whereas IS (n = 15/18.8%) kept reserved for contraindications to reconstructive surgery. For all procedures operative complications decreased from 46.1% (12/26) to 11.0% (6/54) and lethality to 0%. Late complications were related to proctectomy (nerve damage) and construction of IAP (pouchitis in 34.8% and defunctioning of the pouch in 10.4%), whereas IRA was free of specific morbidity so far. Surgery of ulcerative colitis is characterized today by restoration of anal continence. The advantage of the changed surgical concept lies within the ability to perform colectomy at an earlier stage of the disease. Safe construction of IAP is the most important technical progress. Early operation of colitis and late morbidity of pouch justify (preliminary) IRA. Thus, surgical standard in colitis-surgery is defined more individually.
