Adipositaschirurgie: Ablehnung der Kostenübernahme trotz ärztlicher Gutachten

BACKGROUND AND OBJECTIVE

Surgery is an effective method to treat patients with morbid obesity. However health insurance companies frequently refuse to cover the costs for the procedure despite an existing DRG-code for this operation. Individual medical expertise are necessary to receive reimbursement. In the present study the acceptance of medical expertise to receive cost coverage was analysed in our patients of the years 2000-2003 eligible for obesity surgery.

PATIENTS AND METHODS

617 medical expertise of patients eligible for obesity surgery in our hospital were reviewed and the acceptance rate was evaluated. Parameters such as body mass index, personal medical history, diets, comorbidity and prognosis were included. Expertise were submitted to the health care insurance companies and in case of acceptance the operation was performed.

RESULTS

The average age of our patients was 39.1 +/- 11.2 years, 72.1% were female, 27.9% male. The average BMI was 47.5 +/- 7.4 kg/m2. There was a high incidence of comorbidity in these patients (58.7% arterial hypertension, 38.6% diabetes mellitus, 95.8% dyspnoea, 96.1% arthropathy, 89.0% psychosocial disorders). The difference between accepted and non-accepted regarding these secondary complications was not significant. 209 patients (33.8%) were operated. 14 patients of these paid the costs themselves. Only in 195 cases (31.6%) the health care insurance company covered the costs for the operation.

CONCLUSION

The high number of refusals of medical expertise is not justified in view of the strict criteria for indication, the high frequency of comorbidity and the good results after the operation.

Contact dermatitis to hair dyes in a Danish adult population: an interview-based study

BACKGROUND

Contact allergy to hair dye ingredients is a well-known entity seen both in consumers using hair dyes and among hairdressers with occupational contact dermatitis. Surveys show that consumers with even severe adverse skin reactions to hair dyes only rarely contact the healthcare services. The frequency of hair dye-induced skin reactions in the consumer population is unknown.

OBJECTIVES

An epidemiological investigation with the aim of establishing the proportion of hair dye-induced skin reactions was performed in a population-based sample.

METHODS

A representative random sample (n = 4000) was taken of the Danish adult population. Personal interview questions were asked regarding adverse skin reactions to hair dyes, either compatible with a classical allergic eczematous reaction with redness, scaling and itching or a severe allergic reaction with oedema of the forehead and face. The response rate was 65.2%.

RESULTS

A total of 18.4% of the male respondents and 74.9% of the female respondents had at some point dyed their hair. The median age at first hair dyeing was 16 years (range 1-80). Adverse skin reactions to hair dyes compatible with an allergic reaction were reported in 5.3% of individuals who had ever used hair dye. Of these, only 15.6% had been in contact with healthcare services after the hair dye reaction. Having had a temporary tattoo was not a significant risk factor for an adverse reaction to hair dyes.

CONCLUSIONS

The rate of adverse allergic skin reactions to hair dyes was higher than expected from patch-test studies. Only by studying the clinical types of adverse reactions to hair dyes will it be possible to gather a complete epidemiological picture of the nature and extent of the problems related to hair dye ingredients.

Factors of importance for scintigraphic non-visualisation of sentinel nodes in breast cancer

PURPOSE

The aim of this study was to analyse different factors of possible significance for non-visualisation of sentinel nodes (SNs) by preoperative lymphoscintigraphy, in order to enable improvement of the success rate of SN visualisation through modification or alteration of some of the factors.

METHODS

Between March 1998 and January 2003 we analysed a series of 442 women with unilateral stage T1 and clinical N0 breast cancer. Lymphoscintigraphy was performed after periareolar or peritumoural injection of 99mTc-albumin nanocolloid, with image acquisition after 2-6 h or 18-24 h. Until January 2001, all patients received around 20 MBq tracer, irrespective of time to operation. From January 2001, patients injected on the day before surgery received at least 100 MBq while patients injected on the day of surgery received around 50 MBq.

RESULTS

An SN was visualised in 87% of the patients, and at surgery the SN was detected with the hand-held gamma probe in 42% of the remaining patients. By multiple logistic regression analysis, statistically significant independent variables that increased the risk for non-visualisation were increasing age (p=0.0007), increasing body weight (p=0.0189) and peritumoural injection (p<0.0001). Significant interaction was found for imaging time and injected activity (p=0.0017).

CONCLUSION

This study conclusively shows that the risk of unsuccessful SN imaging increases with age and body weight. Our findings suggest that the scintigraphic success rate may be improved by periareolar (rather than peritumoural) injection. Early and late imaging procedures are equally efficient, but if a late imaging procedure is used, activity (adjusted for physical decay) in the patient on day 2 should be more than 10 MBq.

Role of somatostatin-14 and its analogues in the management of gastrointestinal fistulae: clinical data

Somatostatin-14 and its analogue octreotide both exert inhibitory effects on gastrointestinal secretions and may therefore be beneficial in the treatment of gastrointestinal fistulae. There are no studies that have compared these two drugs directly and hence this paper aims to review studies that are available for each drug. There are only six controlled studies that have examined the effects of somatostatin-14 and octreotide on fistula output reduction, three for each drug. All studies compared conservative therapy and the drug in combination with conservative therapy. Of the somatostatin-14 studies, two showed a significant effect on output (p<0.05) and the other demonstrated an output reduction on day 1 that was twice that in the control group (NS). Of the octreotide studies, one showed a significant effect (p<0.01) and the other two showed no effect of the drug on output. No study with either drug has demonstrated an increase in the number of patients that have achieved closure. However, a positive effect on the time to achieve closure has been found. Of the five controlled studies with somatostatin-14, all showed a significant reduction in time to closure. Of the two controlled studies with octreotide, one showed a significant reduction (p=0.002) and the other showed no difference. Due to the limited number of trials, a definitive evaluation of the efficacies of somatostatin-14 and octreotide in the treatment of gastrointestinal fistulae is not possible. However, currently available information seems to suggest a considerable benefit of somatostatin-14 when administered in association with standard conservative treatment, but this needs to be confirmed in a large prospective controlled study.

The Swedish laparoscopic adjustable gastric banding for morbid obesity: radiologic findings in 218 patients

OBJECTIVE

The objective of this study was to determine the prevalence and radiologic features of postoperative complications after Swedish laparoscopic adjustable gastric banding surgery and to emphasize the role of the radiologist in the follow-up of those patients, especially in the treatment of complications.

MATERIALS AND METHODS

We reviewed the radiologic findings in 218 consecutive morbidly obese patients after laparoscopic placement of the Swedish gastric banding system. Radiographic studies of the stomach (obtained with liquid barium sulfate suspension) were performed before surgery and 1 month after band placement in every patient. Additional studies in symptomatic patients were performed when needed.

RESULTS

Surgical complications found included misplacement of the band (five patients, 2.3%), slippage of the band (17 patients, 7.8%), and pouch enlargement (eight patients, 3.7%). Technical problems encountered were inversion of the access port (three patients, 1.4%), leakage of the device (two patients, 0.9%), and spontaneous decrease of the stoma size caused by gastritis (seven patients, 3.2%) or the hyperosmolar properties of the IV contrast material (12 patients, 5.5%). Intrinsic abnormalities of gastroesophageal tract seen included trapping of food in the stoma (four patients, 1.8%) and esophagitis (11 patients, 5%).

CONCLUSION

Although, according to the available data, the gastric banding operation with the Swedish band meets the criteria of a low-risk laparoscopic alternative treatment of morbid obesity, the radiologic appearances of various complications may be seen on the images of patients who have undergone the procedure. The radiologist plays a key role in the early detection of those complications and treatment of specific abnormalities.

Social differences in illness and health-related exclusion from the labour market in Denmark from 1987 to 1994

OBJECTIVE

The objectives were first to analyse differences in long-standing illness, limiting long-standing illness, and perceived health as below good in relation to different indicators of social class over time; and secondly to analyse the association of long-standing illness, educational level, age, and gender with employment status.

SUBJECTS AND METHODS

Self-reported information on illness, educational level, employment status, and occupational class was obtained in two nationally representative Danish health interview surveys in 1987 (n=4753) and 1994 (n=4668).

RESULTS

There was a marked increase in long-standing illness from 1987 (33%) to 1994 (38%), especially among women with higher education (13% in 1987 to 26% in 1994). The prevalence of perceived health below good was unchanged (c. 20%) during the same period. Among employed men in 1987 the lowest prevalence of long-standing illness was seen in upper salaried employees (21%) and the highest in skilled workers (35%). In 1994, the difference had diminished and the prevalence rates for the same classes were 28% and 29%, respectively. Among employed women, a similar pattern was seen. The lowest rate in 1987 was seen among self-employed with subordinates (15%) and the highest in self-employed without subordinates (28%). In 1994, the difference was reduced with prevalence rates of 23% and 32%, respectively. In addition, substantial differences in health status between groups with different educational backgrounds were found. The proportion of the population with long-standing illnesses was clearly higher in the group with low education compared with the group with high education. A similar social gradient was found for perceived health as below good. Those with the highest odds ratio of being a disability pensioner are women with long-standing illness, only basic education, and above 55 years of age.

CONCLUSION

In conclusion, the study showed that the prevalence of long-standing illness increased from the mid-1980s to the mid-1990s, whereas perceived health below good was unchanged. In 1994, there was a remarkable difference in health between employed and non-employed people, indicating a health-related exclusion from the labour market. This may explain why, in 1994, smaller occupational class differences were found in the prevalence of long-standing illness among employed people compared with the findings in 1987, whereas the health differences remained in the different educational groups. Women above 54 years of age with basic education only and long-standing illness have the highest odds ratio of permanent exclusion from the labour market.

Hyperthermic intraperitoneal chemoperfusion in the treatment of locally advanced intra-abdominal cancer

BACKGROUND

Surgical treatment of intra-abdominal cancer is often followed by local recurrence. In a subgroup of patients, local recurrence is the sole site of disease, reflecting biologically low-grade malignancy. These patients might, therefore, benefit from local treatment. Recently, debulking surgery followed by hyperthermic chemoperfusion has been proposed in the treatment of locally advanced or recurrent intra-abdominal cancer. This paper reviews the rationale and assesses the currently accepted indications for and results of this novel treatment.

METHODS

A systematic web-based literature review was performed. Information was also retrieved from handbooks, congress abstracts and ongoing clinical trials.

RESULTS

A growing body of experimental evidence supports the use of hyperthermia combined with chemotherapy as an adjunct to cytoreductive surgery. Randomized clinical trials are available to support its use in the treatment and prevention of peritoneal carcinomatosis following resection of pathological tumour stage pT3 or pT4 gastric cancer; several other phase III trials are ongoing. Numerous phase I and II trials have reported good results for various other indications, with acceptable morbidity and mortality rates. Case mix, limited patient numbers and absence of a standardized technique are, however, a drawback in many of these series.

CONCLUSION

For a subgroup of patients with peritoneal cancer without distant disease, debulking surgery followed by hyperthermic chemoperfusion may offer a chance of cure or palliation in this otherwise untreatable condition. This novel therapy should, however, be considered experimental until further results from ongoing phase III trials become available.

Giant intraluminal duodenal diverticulum: conventional barium study and computed tomography findings

A case is reported of an asymptomatic intraluminal duodenal diverticulum (IDD) in a 21-year-old male patient with associated congenital abnormalities. During endoscopy for anemia an ostium in the duodenum was visualized, presumed to be the entry to an extraduodenal diverticulum. Upper gastrointestinal (UGI) barium examination showed, however, findings compatible with IDD. This diagnosis was supported by an abdominal computed tomographic (CT) examination. Surgical resection revealed a web in D2 with coexistent large IDD.

Evaluation of graft viability in heterotopic auxiliary liver transplantation in the rat

In the rat model of heterotopic auxiliary liver transplantation, the coexistence of the engrafted liver and the recipient's native liver makes it difficult to evaluate the posttransplant graft viability. In this study, auxiliary liver transplantation was performed in Wistar rats, in which the recipient's native liver was handicapped with a 68% partial hepatectomy and a common bile duct ligation. Serum biochemistry of the liver was analyzed and compared with that of the selected control group. The surgical handicap of the liver showed severe damaging effects: the handicapped native livers appeared atrophic at autopsy, and no long-term animal survival could be achieved without an auxiliary liver transplantation. As the engrafted liver corrected the cholestasis of the handicapped native liver, significant differences of serum biochemistry were found between the transplanted group and the control group: for bilirubin concentration and gamma glutamyl transferase activity from postoperative day 3 to 28 (p < .05); for alkaline phosphatase on days 3, 7, 14, and 28 (p < .05); for alanine aminotransferase activity on days 3 and 14 (p < .05); and for aspartate aminotransferase activity on day 14 (p < .05). The efficiency to induce hepatic failure and to hamper its regeneration capacity in the native liver makes animal survival and liver biology as reliable parameters to evaluate the posttransplant graft viability in this rat model.

Alternative technique for creation of a proximal gastric pouch in laparoscopic adjustable silicone gastric banding

BACKGROUND

Laparoscopic adjustable silicone gastric banding (LASGB) has become a widely used procedure for the treatment of morbid obesity. The original operation, as described by Kuzmak, has been subjected to modifications. Construction of a proximal gastric pouch is an important part of the operation. Until now, we used the technique of Niville. Since this was often complicated by gastric bleeding and/or serosal tears, we developed a new technique to construct a pouch.

SURGICAL TECHNIQUE

A new technique, using a thread previously fixed to that portion of the fundus that will be used to construct the pouch, is described.

CONCLUSION

A safe and easy adaptation of the LASGB technique is proposed to create the gastric pouch.

Reduced incidence of acute renal graft failure in patients treated with peritoneal dialysis compared with hemodialysis

In a case-control study performed in two centers, the incidence of delayed graft function (DGF), defined as the necessity to perform dialysis after transplantation, was analyzed according to prior treatment with continuous ambulatory peritoneal dialysis (CAPD; n = 117) or hemodialysis (HD; n = 117). The patients were matched for age, sex, HLA compatibility, and cold ischemia time. The patients were followed up for 6 months to monitor renal graft function (serum creatinine [Screa] level immediately after transplantation, at 6 weeks, at 6 months) and postoperative complications. No significant differences were found in the warm ischemia time of the graft or previous time on dialysis. DGF occurred in 27 CAPD patients (23.1%) and 59 HD patients (50.4%; P < 0.0001). The decline in Screa level after transplantation was faster in CAPD patients: the time for Screa level to decrease 50% after transplantation (T1/2Screa) was reached after 5.0 +/- 6.6 days in the CAPD group compared with 9.8 +/- 11.5 days in the HD group (P < 0.0001). A greater number of patients developed acute rejection episodes in the CAPD group (P < 0. 05), but Screa level was not different in the two groups 6 weeks and 6 months after transplantation. No differences were observed in infectious or surgical complications. This study shows that immediate renal function after transplantation is better in CAPD patients and that peritoneal dialysis should be considered as a first choice for pretransplantation therapeutic modality.

Initial experience with the use of preoperative transarterial chemoembolization in the treatment of liver metastasis

We retrospectively evaluated the influence of preoperative Transarterial Chemoembolization (TAE) on technique and complications, tumour histology, and disease-free survival after surgery for hepatic metastasis. In a 2-year period, a total of 23 patients were treated. In a first group of 14 patients, preoperative TAE was performed; in a second group of 9 patients only surgical resection was done. Extensive tumour necrosis was seen in the majority of patients treated with TAE; in tumours with an important fibrotic component, embolization was less effective. No significant effect was seen on operating time, transfusion requirement or perioperative complication rate. In the group of patients who underwent TAE, survival rate was 93% after a mean follow-up period of 15.5 months (SD: 12.5); recurrence was seen in only 8% of the survivors. In the second group, however, mortality was 33% after a median follow-up of 17.5 months (SD: 10), and recurrence was present in 66.7% of the survivors. These results indicate that preoperative TAE reduces the recurrence rate in the first postoperative year. Thereby survival may be improved in patients with resectable metastatic liver cancer.
