Combined primary subintimal and endoluminal angioplasty for ischaemic inferior-limb ulcers in diabetic patients: 5-year practice in a multidisciplinary 'diabetic-foot' service.

INTRODUCTION: This study aims to assess the patency, the clinical success and the limb-salvage rates of combined subintimal (SA) coupled to endoluminal angioplasty (EA) as the initial treatment of ischaemic inferior-limb ulcers in diabetic patients and to study the influence of other concurrent factors in the tissue-healing process. MATERIALS AND METHOD: Since September 2002 until December 2007, a consecutive series of 176 limbs with manifold ischaemic wounds in 161 diabetic patients were treated by associated multilevel angioplasties in a multidisciplinary 'diabetic-foot team' (a third-line diabetic-care institution integrating two departmental hospitals). There were 98 associated SA with EA procedures, 26 re-vascularisations by single SA technique and 52 others including selective multilevel EAs that were retrospectively reviewed. The mean follow-up period was 22.1 months (in the range of 1-50 months) by clinical and duplex evaluation (every 6 months). RESULTS: The initial technical success was noted in 149 limbs (84%). For the single or associated SA procedures, 102 of 124 procedures were successful (82%) and 145 of 150 of the miscellaneous EAs (96%) evinced an equally favourable outcome. The 27 initially failed endovascular procedures (22 SA and five EA) required 16 surgical re-vascularisation, eight adjuvant endovascular procedures besides three amputations. A total of 21 secondary and five tertiary angioplasties were equally necessary during the entire follow-up period of these patients. The 30-day survival rate was 99% (one patient died from myocardial infarction). In a intention-to-treat analysis, the cumulative primary and secondary patencies at 12, 24, 36 and 48 months were 62%, 45%, 41% and 38%, together with 80%, 69%, 66% and 66%, respectively. The aggregate clinical success rates at the same intervals were 86%, 77%, 70% and 69%, while the corresponding limb-salvage proportions showed 89%, 83%, 80% and 80%, respectively. The primary patency was negatively affected at 1 and 4 years by the length of the occluded segment (>10 cm) and the end-stage renal disease (ESRD) (p<0.0001). The limb-salvage rates were unfavourably influenced at the same periods by the extent of tissue defects (>3 cm), the ESRD and the presence of osteomyelitis. In addition, at 4 years, the age (>70 years), the accompanying peripheral neuropathy, the bedridden status and the presence of cardiac failure (left ventricular ejection fraction (LVEF)<30%) appeared equally as negative predictors (p<0.0001) for wound healing and limb rescue. CONCLUSION: Primary angioplasty represents a low aggressive and efficacious method to improve the healing process in diabetic ischaemic ulcers. However, beyond appropriate re-vascularisation, even repetitive if necessary, achieving satisfactory limb-salvage rates probably implies a multidisciplinary control of the presenting risk factors for wound healing as well.

Large non-anastomotic false aneurysm on dacron aortobifemoral prosthesis solved by endovascular exclusion.

Aortic and iliac pseudo-aneurysms are infrequent but challenging complications after open surgical graft reconstructions, mostly having para-anastomotic localisations. The true corporeal peri-prosthetic false aneurysms are, up until now, very rarely documented presentations. We report the clinical case of an 8.8 cm diameter non-anastomotic and aseptic pseudo-aneurysm developed on aorto-bifemoral Dacron prosthesis in a symptomatic and high surgical risk patient. Considering the clinical presentation and the anatomical features, a chronic tear of the posterior prosthetic wall by prominent aortic remnant calcifications was evoked as the possible aetiology. An endovascular exclusion, using a tapered aorto-uni-iliac endograft coupled to a femoro-femoral bypass revascularisation, was technically successful. Despite scarce published clinical data focusing on the optimal treatment dedicated to this category of false aneurysm, this approach is thought to be beneficial in selected cases of high-risk surgical patients.

Epidemiological profile of geriatric patients admitted to the emergency department of a university hospital localized in a rural area.

The number of geriatric patients admitted to the accident and emergency department is growing. These patients also present increasing functional dependence and a large panel of associated diseases and associated problems. For the purpose of describing this phenomenon, we prospectively studied the epidemiology of patients 75 years and older entering the emergency department of a university hospital localized in a rural area. From January 1996 up to January 1997, 1298 patients aged 75 years or older were admitted to the emergency department. This age group represented 12.3% of all the patients admitted during the period. The gender distribution was almost equal: 56% were female and 44% male. Most of them (75%) were referred by their general practitioner although 15% came spontaneously. The most common complaints were, in decreasing order: general condition impairment (21.5%), dyspnoea (15%), falls and traumas (15%), abdominal problems (13%), thoracic pain (9%), syncope, dizziness (7%) and stroke (5.5%). Hospitalization was necessary in 69% of cases. Among the patients coming spontaneously a larger proportion (55%) were sent back home compared with only 25% of those referred by their general practitioner.

[Quality of the care of the pediatric patient admitted to the emergency room]. / Qualité de la prise en charge de l'enfant admis en salle d'urgence polyvalente.

AIM: By a prospective study, authors tried to analyse the quality of management of the pediatric patient admitted in the emergency department. POPULATION AND METHODS: One hundred admission files were prospectively analysed for characteristics of age (mean age: 70 months), effectiveness of measurement of physiological parameters, evaluation of appropriateness of nursing management according to recorded parameters, length of stay in the emergency department according to the need for hospitalization, blood tests, X-rays and the seniority of the attending medical staff. RESULTS: Parameters were not, or only incompletely, recorded in 65 files. . Although all were recorded in the remaining 35 files, subsequent management was inadequate in seven cases. Mean length of stay in the emergency department was 116 minutes, influenced by the need for hospitalization (145 minutes compared to 102 minutes for the non-hospitalized children), timing of admission (mean: 125 minutes from 8 am to 6 pm, compared to 94 minutes from 6 pm to 8 am), need for blood tests, X-rays or both (mean: 122, 107 and 170 minutes respectively, compared to 55 minutes when no complementary exam was asked) and seniority of attending medical staff (mean: 65 minutes for permanent staff compared to 116 minutes for fellows). CONCLUSIONS: Measurement of physiological parameters must be standard practise in the management of pediatric patients admitted to the emergency department and must lead to appropriate management without undue delay. In order to reach this goal, emergency departments should be more adequately staffed with nurses and senior doctors specifically trained in the care of the pediatric patient. Blood tests and X-rays should be more readily available.

Spiral computed tomography with three-dimensional reconstructions for severe blunt abdominal traumas: a useful complementary tool?

Spiral computed tomography (CT) has proved to be a valuable tool by providing three-dimensional (3D) images of the studied structures. We hypothesized that a more realistic depiction of lesions by 3D CT could be of interest for surgeons who are treating blunt abdominal traumas and lead to less inappropriate triage. A good working relationship between surgeons and radiologists allowed us to perform a 3D CT examination in six patients. In the first patient, the 3D CT accurately demonstrated spleen fragmentation without devascularized fragment. The second patient had complete devascularization of the spleen upper pole. Conservative treatment was pursued for both patients. For the third patient, 3D CT helped us to differentiate peritoneal-perisplenic fluid from subcapsular fluid. The fourth patient had minor spleen injury associated with severe lacerations of the left kidney. 3D CT showed a complete separation of the kidney lower pole. A delayed partial lower nephrectomy was performed. The fifth patient presented a fragmented spleen and transient massive haematuria related to a well-contained laceration of the kidney upper pole that were amenable to nonoperative management. The sixth patient was emergency operated for active bleeding from a fragmented spleen. 3D CT performed 2 months after spleen repair allowed the assessment of the amount of devascularized tissue, as well as the status of the upper abdomen arteries. For haemodynamically stable patients, 3D CT could be a helpful addition to conventional axial CT for quantifying blunt abdominal traumas, for making the choice between nonoperative and operative treatment, but also between emergency and delayed surgical strategy.

Direct carbon dioxide insufflation of the retroperitoneum under laparoscopic control for renal and adrenal surgery.

OBJECTIVE: Assessment of the videoscopic approach to the retroperitoneal space in the vicinity of the kidney and the adrenal gland. DESIGN: Open study. SETTING: University hospital, Belgium. SUBJECTS: 10 patients who underwent 11 operations (adrenalectomy, n = 3, nephrectomy, n = 5, partial nephrectomy, n = 2, and renal cystectomy, n = 1). INTERVENTIONS: Direct CO2 insufflation of the retroperitoneal space in order to obtain a convenient retroperitoneal working space for renal and adrenal surgery. OUTCOME MEASURES: Feasibility, morbidity and mortality. RESULTS: 8 patients were operated on exclusively by the retroperitoneoscopic approach; 2 required the retroperitoneal and transperitoneal routes to be combined to complete an adrenalectomy. No patients required blood transfusion and no patient died. Median postoperative stay was 3 days. CONCLUSION: The CO2 insufflation technique of the retroperitoneum is safe and reproducible. Nevertheless, far from excluding each other, both approaches-laparoscopic and retroperitoneoscopic-are complementary in difficult cases, particularly for adrenal endoscopic surgery and for larger renal lesions.

Blunt renal traumas: contribution of spiral CT with three dimensional reconstruction to the surgical decision process?

Spiral CT has proved to be a valuable tool by providing various kinds of three-dimensional (3D) images of the studied structures. Such 3D images, which offer a more realistic depiction of the lesions, could be of interest for surgeons who are attempting to treat conservatively blunt abdominal traumas and lead to less inappropriate triage between conservative and operative management particularly for renal trauma. A good working relationship between surgeons and radiologists allowed us to perform an early follow-up 3D spiral CT on a commercially available spiral CT scanner. In the first adult patient, the 3D CT demonstrated minor spleen injury associated with severe lacerations of the left kidney with complete separation of the kidney lower pole. A delayed partial lower nephrectomy was performed. For the second 12-year-old patient presenting with severe spleen trauma and macroscopic hematuria, the 3D CT accurately documented the spleen and renal lesions that were safely amenable to nonoperative treatment. For hemodynamically stable patients, 3D CT is a potentially helpful addition to conventional axial CT for quantifying blunt renal traumas and for making the strategic choice between nonoperative, emergency or delayed surgical treatment.

Splenic infarction: report of three cases of atherosclerotic embolization originating in the aorta and retrospective study of 64 cases.

The authors report 3 cases of thromboembolic splenic infarction due to atherosclerosis of the thoracic aorta and the splenic artery. On this occasion, a retrospective analysis of 64 splenic infarcts showed that, in contrast to the literature, the leading aetiology in our series consisted of haematologic disorders (50%), followed by cardiovascular diseases (29%) and by digestive disorders (20%). Mean age was 58 +/- 17 years and 50% of the patients were aged below 60 years. Hospital mortality rate was high (34%) but not directly related to splenic infarction, suggesting that splenic infarction often occurs in the setting of severe underlying diseases. Splenic infarct is part of the differential diagnosis of the left upper quadrant pain and can also mimic renal disorders. Laboratory values may show an inflammatory syndrome and an increase in serum lactate deshydrogenase. Diagnosis is often made by CT scan and can be confirmed by a selective spleen scintigraphy. Transoesophageal echocardiography is essential in the detection of cardiac and thoracic aorta embolic material.

Non-therapeutic operations for penetrating trauma: early morbidity and mortality.

A prospective study was carried out to assess the incidence and type of complications after non-therapeutic operations for penetrating trauma. A total of 372 operations were performed on 368 patients with penetrating injuries to the abdomen (240 procedures), chest (49), neck (48) and extremities (35). There were 46 negative or non-therapeutic operations. The incidence of major complications directly related to anaesthesia or operation in this group of patients was 4 percent (two patients). The operation might have contributed to a further three major complications. The mean hospital stay for patients undergoing uncomplicated non-therapeutic operation was 4.1 days; for those with complications it was 21.2 days. It is concluded that non-therapeutic operations for penetrating trauma carry a significant morbidity rate. A policy of selective conservatism is advocated.

[A new method for pseudocysto-duodenostomy as therapy in pancreatic pseudocyst in chronic pancreatitis]. / Ein neues Verfahren der Pseudozystoduodenostomie zur Therapie der Pankreaspseudozyste bei chronischer Pankreatitis.

Reference in the surgical literature to the use of pseudocysto-duodenostomy whether laterolateral by Ombredanne [6] or transduodenal by Kerschner [4], is uncommon. The author with the aid of specially designed three-jaw prong, now, prefer to use pseudocysto-duodenostomy. From 1970, 411 patients underwent surgery for complicated chronic pancreatitis. 67 of the 93 patients requiring an internal cysto-intestinal procedure were treated by pseudocysto-duodenostomy; 11 additional patients were treated by derivation in the first retroperitoneal transposed jejunal loop. Postoperative mortality for the first month was 0%. The actuarial survival rate at 5 years was 86.9%. These satisfactory results have encouraged us to compare this new operative method with cystojejunostomy. It allows pancreatic secretions to drain into their natural anatomical site. Compared with external drainage it avoids the often prolonged and costly complications.
