Should keratoacanthoma be treated surgically?

Keratoacanthoma is a rapidly growing cutaneous neoplasia of adult persons that may regress spontaneously. It is believed to arise from the hair follicles. It is sometimes difficult to distinguish keratoacantoma from squamous cell carcinoma either clinically or histologically. During ten years period (1992-2001) we were treating 18 patients with keratoacanthoma of the skin. We discuss here our experience with this tumor, and we conclude that early, complete excision is the treatment of choice for it.     

What adrenal incidentalomas are to be operated?

AIM OF THE STUDY: The goal of this retrospective study was to recognize the incidence of adrenal tumors called incidentalomas, that are in fact symptomatic or hormone secreting tumors, to assess if the diagnostic criteria proposed in the literature are reliable for adrenal tumors found incidentally. PATIENTS AND METHOD: The records concerned 147 patients operated between April 1981 and December 2000 for an adrenal mass measuring 3 cm in diameter and larger on CT scan. Clinical and laboratory findings as well as hormone levels and imaging examinations (CT Scan, IRM, scintigraphy) were correlated with operative findings and results of histologic examinations. One hundred and three patients were operated by a traditional approach and forty four by videoendoscopic techniques. RESULTS: In 41 patients (28%), the tumors had to be classified as false incidentalomas (group 1) postoperatively. In 106 patients (72%), the nature of tumor was non definite. In this group 2, there were ten malignant tumors, two pheochromocytomas and 94 benign lesions. Age of patient, size of tumor, increase in size over time and radiological appearance represent criteria that are not reliable to separate malignant from benign tumors. CONCLUSIONS: Tumors of indeterminated and non specific nature only should be classified as incidentalomas. Imaging techniques as well as other criteria of malignancy cannot be relied upon to separate benign from malignant tumors. The risk even small of cancer or pheochromocytoma leads us to recommend excision of tumors > or = 3 cm in radiological diameter. The videoendoscopic approach is a good alternative to open operation in centers with this special expertise.     

Should calcaneal fractures be treated surgically? A meta-analysis

A MEDLINE search from 1980 through 1996 revealed 1845 articles dealing with calcaneal fractures. Six of these articles that compared operative versus nonoperative treatment for displaced calcaneal fractures met the minimum criteria for inclusion in a meta-analysis. A statistical summary of information across the six articles revealed a trend for surgically treated patients to be more likely to return to the same type of work as compared with nonoperatively treated individuals. There also was a trend for nonoperatively treated patients to have a higher risk of experiencing severe foot pain than did operatively treated patients. Unfortunately, none of the other outcomes could be summarized formally across studies using statistical techniques because of variability in reporting across studies. Although the tendency was always for operatively treated patients to have better outcomes (reaching statistical significance in some of the articles), the strength of evidence to recommend operative treatment for displaced intraarticular calcaneal fractures remains weak. A large prospective randomized controlled trial should be able to answer this question.     

How should peritoneal-dialysis-associated peritonitis be treated?

In this Practice Point commentary, we discuss Wiggins et al.'s systematic review of the treatment of peritonitis, a serious problem in peritoneal dialysis patients. Wiggins and co-workers reported that most antibiotic classes were similarly effective for the treatment of peritonitis. Despite the limited data available, the investigators found that the intraperitoneal route was more effective than the intravenous route in preventing treatment failure, that intermittent dosing of various antibiotics was as effective as continuous administration of these drugs, and that glycopeptide-based regimens were more likely than first-generation cephalosporins to achieve a complete cure. Here, we discuss the importance of treating peritonitis and the lack of and limitations of existing data, and emphasize the urgent need for well-designed, large randomized trials in this area.     

When should peripheral lymphadenopathy be biopsied?

Excisional biopsy for lymphadenopathy is sometimes necessary to confirm the diagnosis of lymphoma or metastatic disease from an unknown primary site. Lymph node excision should be preceded by less invasive approaches which may confirm a benign pathology. Collaboration with medical and hematologic specialists will allow a well-reasoned diagnostic approach with complementary studies; excisional biopsy, if necessary, will then be done under the best conditions and in the most cost-efficient manner.     

Management of recurrent carotid stenosis: Should asymptomatic lesions be treated surgically?

Purpose: The purpose of this study was to determine factors that may influence patient selection for surgery in recurrent carotid stenosis (RCS) and to contrast the results of primary and secondary carotid endarterectomy (CENDX) with regard to operative morbidity and stroke prevention.Methods: Forty-eight patients who underwent CENDX for RCS (RCS-OP group) were compared with a contemporaneous group of 40 patients who on at least one post-CENDX duplex ultrasonography study had a greater than 50% stenosis but did not undergo operation (RCS-NO-OP group). This latter group was drawn from 1053 follow-up duplex studies in 348 patients who underwent primary CENDX between the years 1983 and 1993. Each of these two groups was compared with a metanalysis of six key series derived from the literature.Results: No significant differences were seen in the demographics or the incidence of risk factors between the two groups except for a higher incidence of coronary artery disease (p < 0.03) and peripheral vascular disease (p < 0.001) in the RCS-OP group. The operation-specific stroke rate was 2.1%, and the 30-day mortality was also 2.1%. Symptomatic RCS was the indication in 56% of cases. Important anatomic differences were found between groups. The duplex/arteriographic degree of stenosis was greater than 90% in 75% of the patients in the RCS-OP group, whereas only 10% of the patients in the RCS-NO-OP group had greater than 80% stenosis, most being in the 50% to 80% range. An unexpected finding was the sudden progression to occlusion in 10 (25%) of 40 in the RCS-NO-OP group, with 2 (5%) of 10 of the occlusions presenting as unheralded strokes. Overall, a stroke without an antecedent transient ischemic attack occurred in 3 (7.5%) of 40 of patients in the RCS-NO-OP group, all in patients with greater than 75% stenosis on their last documented scan preceding the stroke.Conclusion: Given the relatively low stroke rate with surgery in the RCS-OP group (2.1%) and the higher incidence of unheralded strokes (7.5%) in the RCS-NO-OP group, a more aggressive approach may be warranted in patients with asymptomatic high-grade (>75%) RCS, a strategy not unlike that adopted for primary CENDX.

Asymptomatic osteonecrosis: should it be treated?

Currently, there is no consensus regarding the treatment of precollapse osteonecrosis, particularly for asymptomatic osteonecrosis. With approximately 10,000 to 20,000 new cases of osteonecrosis a year, no single surgeon or center has the kind of experience that is able to address the most important questions concerning this disease. The literature strongly documents that symptoms of osteonecrosis will progress. Although the literature also supports the progression of asymptomatic osteonecrosis to symptomatic osteonecrosis on to collapse, that support is less convincing. Progression is proportional to lesion size, with small lesions (< 15% of femoral head involvement by volume) unlikely to progress. Although the results of core decompression have been somewhat controversial, the weight of the literature supports both the efficacy and safety of the procedure. The decision to treat osteonecrosis with core decompression is primarily based upon lesion size and stage of disease and does not necessarily depend on whether the patient is symptomatic. As large lesions (> 30% of the femoral head) are less likely to be successfully treated by core decompression and small lesions (< 15% of the femoral head) are less likely to progress, asymptomatic lesions within these ranges can be observed. The literature supports the position that moderately sized lesions (15-30% of the femoral head) should be treated by core decompression (with or without bone grafting).     

When should quality of life be measured after radical cystectomy?

AIM: In this prospective study our aim was to establish the time it takes cystectomized patients' to adapt to their new health status. MATERIALS AND METHOD: A total of 68 patients, having radical cystectomy for bladder cancer (64 males and 4 females) were enrolled in the study. The mean age of the group was 55.4 +/- 8.0 years (range 38-70 years). Continent urinary diversion was applied to 17 while the rest had incontinent urinary diversions. There was no statistical difference between those who had continent and incontinent diversions in regard to pre-operative stage. All patients were given a Beck's Depression Inventory (BDI), an EORTC-QLQ C-30 Version 2 (European Organization for Research on Treatment of Cancer Quality of Life Questionnaire C-30 Version 2) quality of life measurement scale pre-operatively, and post-operatively 3, 6, 12 and >12 months (every 6 months). Log-rank and Student's t-test was used for statistical analysis of the results. RESULTS: The mean follow-up of the study group was 27.7 +/- 7.3 months (range 12-46 months). Five patients at the first 3rd-month control, seven at the 6th-month control and eight at the 12th-month control did not appear for interview, but their available results were also included in the overall assessment. The mean functional score of the study group, evaluated by QLQ C-30, was 80 +/- 25.4 pre-operatively. There is dramatic decrease at the 3rd-month control (56.9 +/- 25.1; p < 0.01). The overall functional score after 12 months (80 +/- 20) is back to the pre-operative value. The mean symptom score of the group pre-operatively was 29.5 +/- 16.7, which showed similar results at 3 and 6 months post-operatively of 29.8 +/- 16.7 and 30.6 +/- 19.4, respectively (p > 0.05). At the 12th-month and thereafter the symptom scores of the patients decreased significantly in comparison to both the pre-operative and the post-operative 3-6 months (23.4 +/- 13.7 and 21.8 +/- 18.5, respectively; p < 0.01 for all). The self-rating general health status of this group was lowest pre-operatively with a mean of 49.8 +/- 26.5. Interestingly, there was a statistically significant increase in the general health status assessment of the patients even at the early post-operative period of 3 months (61.4 +/- 17.2; p < 0.01). The increase in the well-being of the patients increased linearly until the 12th-month control and stabilized thereafter. There was a 23% pre-operative depression rate, which comes down to 16% at the 12th-month control. The peak depression scores suggesting depression are observed at the 3rd-month controls. There is a gradual decrease in depression score starting from the 6th-month controls and all reach minimum scores after 12 months. Ninety-six percent of the study group showed scores even lower than the pre-operative ones. The mean pre-operative and post-operative 12th-month control scores were 11.5 +/- 7.7, and 8.1 +/- 6.8, respectively (p < 0.01). CONCLUSION: Both psychological and health-related quality of life measures come to baseline values and stabilize after the 12th-month period, suggesting that the time frame for the adaptation of patients is 12 months in patients undergoing radical cystectomy surgery. Therefore, we believe it is better to perform any quality of life assessment as an end-point criterion for comparison of treatment modalities in radical cystectomy patients after 12 months.     

When should Open Surgery be the Initial Option for Critical Limb Ischaemia?

ObjectivesThe treatment paradigm for patients with critical limb ischaemia (CLI) has changed over the past decade with an increase in endovascular interventions. Accompanying this shift has been a fundamental question as to whether open surgery or endovascular therapy represents the optimal treatment for CLI.DesignReview.MethodsA review of open versus endovascular surgery was performed. The supporting arguments by respective clinicians of both an ‘open first’ and an ‘endo first’ approach are summarised, followed by the available evidence in the literature for each. A summary of an informal survey of endovascular surgeons regarding five indications for an ‘open first’ approach to CLI are reviewed. Present and future clinical tools and research for providing a more objective decision for intervention in CLI are then summarised.ResultsSupporters of either an ‘open first’ or ‘endo first’ approach make claims which are not entirely supported by the current level 1 evidence. Five conditions which endovascular surgeons agree that patients with CLI should be treated primarily by open revascularisation include common femoral artery pathology; arterial occlusions caused by extrinsic compression pathologies; extensive foot gangrene/sepsis; young patients and those requiring dependent-free soft tissue reconstructions where durability is paramount; and infrageniculate popliteal and proximal tibial occlusion with single, distal tibial target vessel. Clinical scoring systems and mathematical modelling of lower extremity disease assist in making a prospective intervention decision.ConclusionThe treatment of CLI has changed and continued clinical and research work is focussed on which intervention is more effective. While more attempts at endovascular treatment are made, there remain specific indications for open surgical treatment of CLI. As more work is done towards determining optimal intervention choices on a patient-specific basis, clearer indications for either intervention will emerge.
