[Stomach saving duodenopancreatectomy. Indications and contraindications. The most important surgical steps].

Discussion on pylorus-preserving pancreatoduodenectomy (PPPD) in case of ductal adenocarcinoma is controversal. Aim of the present study was the comparison of survival in patients resected by the classic Whipple operation (Whipple) or the pylorus-preserving procedure. From April 1986 to June 1998 all patients operated for proven diagnosis of ductal pancreatic cancer were documented prospectively concerning patient's characteristics, kind of surgery, complications and histopathological staging according to the UICC-classification of 1992. During the observation period 100 patients underwent pancreatoduodenectomy, 38 cases as Whipple, 62 as PPPD. Average of age was 59.9 +/- 10.3 years without significant differences. Mortality was 6.0% in total, 5.5% post Whipple, and 6.5% post PPPD. Eighty-three percent of the resected specimen were node positive. The median survival time was 9.9 and 10.5 months, 5-year survival 2.6% and 10%, respectively without significant differences. Actually, only node positive patients reached 5-year survival. Even better survival figures following PPPD than after classic Whipple procedure make the pylorus-preserving procedure the standard operation in ductal cancer of the pancreatic head. Distal gastric resection is only mandatory in case of tumor involvement of the duodenopancreatic angle. Since only node negative cases survived 5 years, extensive surgery exceeding anatomical pancreatic head resection does not appear to be beneficial.

[Prerequisites, indications and contraindications of IV-lysis of ischemic stroke with rt-PA].

BACKGROUND AND PURPOSE: To evaluate prerequisites, safety, and efficacy of i.v.-thrombolysis of ischemic stroke with rtPA in an academic medical center. METHODS: Over a period of 2 years and 10 months all patients admitted with a diagnosis of stroke were recruited. Inclusion and exclusion criteria for i.v.-thrombolysis were combined from large scale randomized controlled trials, the time window, however, could be extended up to 4 hours in subjects with a negative CT-scan. Prespecified outcome parameters were the modified Rankin Scale (mRS) and the Barthel Index (BI) at 3 months, and symptomatic hemorrhagic complications. Additionally, time parameters, such as onset-admission-time, door-Ct-time, door-needle time, and onset-needle time were recorded. RESULTS: During the reported period 103 patients underwent i.v.-thrombolysis, corresponding to 14.9% of all patients with ischemic stroke, and 47% of patients with ischemic stroke arriving in < 3 hours after symptom onset. The mean baseline NIHSS was 14, the mean mRS 13 (3-34), the mean age 70 (+/- 12) years. The following time intervals were observed: Onset-admission-time 64 min., door-CT-time 27 min., admission-needle-time 80 min., and onset-needle-time 142 min. There were 4 symptomatic intracerebral hemorrhagic transformations, including 3 parenchymal hemorrhages, 2 of them lethal, and one with almost full recovery. According to the mRS, 39% of patients had a good (mRS 0-1), 72% a good to moderate recovery (mRS 0-2). The corresponding figures for the BI were 60% BI 95-100 and 72% BI > 90. The mortality was 15%. CONCLUSION: The i.v.-thrombolysis of ischemic stroke with rt-PA demands appropriate organisation of the pre- and in-hospital phase and can be performed safely and efficaciously in daily clinical routine if inclusion and exclusion criteria as well as all safety measures during the critical phase after therapy are strictly obeyed.

Video-assisted thoracoscopic surgery--indications, results, complications, and contraindications.

In recent times minimally invasive surgery has secured a firm place among the therapeutic options in thoracic surgery. The experience and results gained from video-assisted surgery on 109 patients between January 1, 1992 and July 31, 1993 are critically discussed. The procedure could be completed thoracoscopically on 94 of them. A change of method was necessary nine times for technical reasons and six times for oncological reasons (two times due to metastasis, four times due to bronchial carcinoma). A total of 154 individual operations were conducted. Sixty-three patients with recurrent spontaneous pneumothorax were successfully treated. The relapse rate was 1.5%. With the exception of three rethoracotomies (one due to postoperative hemorrhaging and two to persistent fistula) no significant complications occurred. Further indications included capsulated pleural empyema (n = 1), persistent hematothorax (n = 2), pleurectomy for malignant pleural effusion (n = 2), pleural tumors (n = 3), pulmonary parenchyma (n = 2), interstitial lung diseases (n = 3), bullous emphysema (n = 2), peripheral lung nodules (n = 18), mediastinal tumors (n = 8), and sympathectomy (n = 2). The advantages of video-assisted thoracoscopic surgery for patients include cosmetic considerations, low pain, earlier postoperative mobilization, and for some indications, a shorter operation period. The significant disadvantages for the surgeon are the loss of binocular vision as well as the impossibility of intraoperative palpation.

Isolated coronary artery bypass grafting in patients 75 years of age and older: is age per se a contraindication?

137 patients with a mean age of 77.3 years (Group A) who underwent isolated coronary artery bypass grafting (CABG) were compared to 137 patients with a mean age of 55.6 years (Group B) who also underwent isolated CABG on the same or the adjacent day as the Group A patients. Group A patients were more commonly women, and had a significantly higher incidence of unstable angina, emergency operations, extensive coronary disease, peripheral vascular disease, and multiorgan debility. However, their left-ventricular function and the extent of revascularisation was similar to Group B patients. They also had significantly more operative mortality (7.2% vs 1.45%, p < 0.001). cardiac and non-cardiac complications, and longer hospital stay (14.2 vs 8.8 days, p < 0.001) than group B patients. At a mean follow-up of 29.8 months, no significant differences were noted in Group A versus Group B patients in terms of long-term survival (95% vs 94%), freedom from angina (82% vs 81%), cardiac readmission (10% vs 12%), or in the incidence of new myocardial infarction or new CABG. Actuarial survival at 4 years was 76.9% in Group A patients and 90.1% in Group B patients. Severe angina due to extensive coronary disease commonly makes urgent surgery unavoidable in this growing population of very old patients, but the operative mortality is modest and survivors do enjoy several years of life, remaining as free of angina, etc., as similar but younger patients.

[Are monamine oxidase inhibitors in disposition to malignant hyperthermia contraindicated? Discussion based on a case report].

We report on a young patient with a positive family history for malignant hyperthermia (MH), who was diagnosed as susceptible to MH in our malignant hyperthermia laboratory by the in vitro-contracture test. Prior to the investigation of MH-susceptibility, the patient had been on medication with moclobemide, a monoamine oxidase (MAO) inhibitor, over a period of 13 months for treatment of a hyperactivity disorder. During the therapy with moclobemide no signs of relevant side effects were observed. However, some authors regard MAO-inhibitors as MH-triggering agents. The risk of MH-patients due to the therapy with MAO-inhibitors and the association between MH and the neuroleptic malignant syndrome is discussed in this case report.

Third ventriculostomy for hydrocephalus associated with spinal dysraphism: indications and contraindications.

Twenty-five patients have undergone this procedure at our unit. These constitute 25% of our total experience with endoscopic third ventriculostomy (4). In the patients under 6 months of age, only one out of 11 patients has had a successful long-term result despite initial good fenestration of the floor of the third ventricle. These patients were selected on the basis of their adequate third ventricular size and a relatively slowly progressive hydrocephalus. Fourteen patients had a ventriculostomy performed instead of shunt revision. In 13 patients this has been a success long term. All of these patients had a Heyer-Schulte valve with antisiphon device installed for months, or more often, years, prior to the third ventriculestomy. We believe that the difference in these two groups is due to a very poor cerebrospinal fluid(CSF)-resorptive capability in patients immediately after back closure due to the prior venting of CSF into the amniotic sac. The absorptive capacity seems to improve with the passage of time in our patients who have had a shunt system that maintains a relatively normal intracranial pressure and thus contributes to the development of the patient's CSF-absorptive system.
