Outcome and prognosis of isolated carotid vasculitis.

OBJECTIVE: To assess the prognosis and outcome of patients with isolated carotid vasculitis. METHODS: We performed a retrospective multicenter study of 36 patients (median age at diagnosis was 37 [IQR 27-45] years and 11 [31 %] patients were men) with initial presentation as isolated carotid vasculitis. Study endpoints included vascular complications, relapses, and progression to large vessel vasculitis (i.e. Giant cell arteritis or Takayasu). RESULTS: The most frequent involvement was the left internal carotid artery (39 %), and 81 % had stenosis. After a median follow-up of 32 months [IQR 12-96], 21 (58 %) patients had a vascular event, including 31 % of new onset vascular lesions and 25 % of stroke/transient ischemic attack. Patients with stroke had less carotidynia at diagnosis (33 % vs 74 %, p = 0.046), higher significant carotid stenosis (i.e. > 50 %) (89 % vs. 30 %, p = 0.026) and higher severe carotid stenosis (i.e. >70 %) (67 % vs 19 %, p = 0.012), compared to those without stroke. Twenty (52 %) patients experienced relapses. High CRP at diagnosis was associated with relapses (p = 0.022). At the end of follow-up, 21 (58 %) patients were classified as having Takayasu arteritis, 13 (36 %) as isolated carotid vasculitis, and two (6 %) as giant cell arteritis. CONCLUSION: Carotid vasculitis may occur as a topographically limited lesion and is associated with significant rate of vascular complications.

Protocol optimization of sacroiliac joint MR Imaging at 3 Tesla: Impact of coil design and motion resistant sequences on image quality.

PURPOSE: To evaluate the impact of coil design and motion-resistant sequences on the quality of sacroiliac magnetic resonance imaging (MRI) examination in patients with spondyloarthropathy. PATIENTS AND METHODS: One hundred and twenty-one patients with suspected sacroiliitis and referred for MRI of the sacroiliac joints were retrospectively evaluated with MRI at 3-Tesla. There were 78 women and 43 men with a mean age of 36.7±11.5 (SD) years (range: 15.8-78.4 years). Conventional and motion-resistant fat-saturated fast-spin echo T2-weighted sequences were performed with two different coils. Image quality was subjectively evaluated by two independent readers (R1 and R2) using a four-point scale. Confidence in the identification of bone marrow edema pattern (BMEP) was also evaluated subjectively using a three-point scale. RESULTS: Phased array body coil yielded improved image quality compared to surface coil (14.1 to 30.4% for R1 and 14.6 to 25.7% for R2; P<0.0001). The impact of the sequence type on quality was also statistically significant (P=0.0046). BMEP was identified in 40 patients and best inter-reader agreement was obtained using the combination of phased-array body coil with motion-resistant T2-weighted sequence (kappa 0.990). The smallest number of indeterminate BMEP zones was seen on MRI set acquired with the phased-array body coil and motion-resistant T2-weighted sequence. CONCLUSION: Phased array body coil and motion-resistant T2-weighted sequences perform better than surface coil and conventional T2-weighted sequences for the evaluation of sacroiliac joints, increasing confidence in the identification of BMEP.

[Presacral myelolipoma: a case report]. / Mielolipoma presacrale: case report.

BACKGROUND: Presacral tumors are more frequently benign, and only occasionally malignant, showing a slow growth and an incidence of 1:40.000. They are asymptomatic in the 26-50% of the cases. When symptoms occur, these are related to the dimensions of the tumor, to its location and to the presence of infection. CASE REPORT: We report the case of a 69-year old woman with a lower abdominal pain associated with paresthesia and ipostenia of the right inferior limb. Digital rectal examination showed a fixed, mild tender and hard tumor of the posterior rectal wall. CT, MR and CT-guided biopsy sequently performed revealed a solid, dishomogeneous mass, located in the presacral region, with a connective likely origin, without pelvic lymphoadenopathy. The operation allowed to esteem a mass which was tenaciously adherent to the sacrum. We performed a total excision. Final histological diagnosis was myelolipoma. CONCLUSIONS: The Authors' opinion is that the en-bloc resection of these tumors with an anterior surgical approach allows a histological diagnosis of the nature, representing the best treatment for potentially malignant lesions, which are frequently radio and chemo-resistant.

Upper gastrointestinal massive bleeding successfully treated intra-operatively with a collagen and thrombin-based high-viscosity gel for haemostasis. Case report.

A 57-year-old male patient was admitted in our Department for a non-variceal upper gastrointestinal massive bleeding. In accordance with the clinical guidelines, the patient underwent an early endoscopy (within 24 hours from admission), which showed the source of bleeding in the second portion of the duodenum. An endoscopic haemostatic injection with dilute adrenalin (epinephrine, 1:10.000) was then performed. After 8 hours, severe recidive bleeding occurred with reduced haemoglobin levels, which led us to an emergency surgical treatment. A gastric resection was performed, followed by the application of high-viscous gel (Floseal) into the source of bleeding within the duodenal lumen. This technique allowed to obtain a definitive haemostasis without long-term complications. Our experience suggests that the intra-operative application of Floseal can be an effective alternative to traditional haemostatic techniques in the emergency surgical treatment of upper gastrointestinal bleeding. This also provides additional time to perform other haemostatic techniques techniques avoiding the precarious haemodynamic conditions of a patient in emergency.

[Laparoscopic adhesiolysis in acute small bowel obstruction]. / Trattamento laparoscopico delle occlusioni del tenue.

At the beginning of the laparoscopic surgery, intestinal obstruction was considered an absolute contraindication for this approach, because of the high risk of injuring the bowel. Today laparoscopic surgery for small bowel obstruction is still under evaluation. Adhesions are the most common cause of obstruction; although an important proportion of these patients can be nonoperatively treated, some of these require immediate operation. The aim of this review was to evaluate the reliability and immediate results of laparoscopic management of small bowel obstruction by postoperative adhesions. Laparoscopic management of acute small bowel obstruction is feasible, but it is often difficult and may be hazardous. The patients with acute obstruction may be undergo laparoscopy after a careful selection. Morbidity is low if the operation is performed by skilled. The immediate benefit is rapid intestinal motility and shorter hospital stay. The long-term effect is the prevention of small bowel obstruction recurrences by new postoperative adhesions.

[Laparoscopic appendectomy]. / L'appendicectomia laparoscopica.

Most laparoscopic procedures are performed on an elective basis. However, as general surgeons have gained more experience with laparoscopy, they are employing this procedure also for the evaluation and treatment of acute abdominal conditions such acute appendicitis, acute cholecystitis, perforated gastroduodenal ulcer and abdominal trauma, acute pancreatitis and intestinal obstruction. Although its advantages are still under debate, the laparoscopic approach has already been adopted by many centers in the emergency setting.

[The role of video-laparoscopy in the management of ovarian swellings]. / Ruolo della videolaparoscopia nel trattamento delle tumefazioni ovariche.

METHODS: Personal experience in videolaparoscopic treatment of 42 ovarian masses during the period September 1991-December 1995 is reported. Seven patients have been operated in emergency, 35 in election. Resection of the masses has been performed by two methods: dissection and electrocoagulation, generally preferred in benign functional cysts; resection by stapler (endo GIA). RESULTS: In 5 of the patients operated in emergency an hemoperitoneum was found because of the rupture of ovarian cyst; in the other two cases, respectively, a necrotic benign cyst twisted on the adnexal axis and a dermoid cyst twisted and necrotic too were found. In the 35 patients operated in election, 33 benign cysts, 1 serous cystoadenoma 1 granulosa tumour were observed. Postoperative course was always excellent, with no painful symptomatology and hospital-stay and convalescence extremely reduced (dismission from hospital approx two days after the operation). CONCLUSIONS: The different aspects which must be evaluated before choosing mini-invasive treatment are discussed. An accurate preoperative study especially by sonography and serous hormonal dosage (in particular CA 125), besides good surgical experience of the operator, are fundamental requisites in order to minimize risks of this procedure and guarantee excellent results.

[Surgical staplers in surgical emergencies. Our experience]. / Le anastomosi meccaniche in chirurgia d'urgenza. Nostra esperienza.

This study describes the use of staplers during surgical treatment performed in emergency from January 1980 to December 1991. For the different, possible operations, some technical notes are examined and results reported. The advantages and risks related to the use of these devices are analysed.

[Acute cholecystitis in videolaparoscopy]. / La colecistite acuta in videolaparoscopia.

The authors describe their experience in 15 cases of acute cholecystitis treated with laparoscopic cholecystectomy in emergency. Only in one patient, affected with an abscess of the upper right abdominal space, a laparotomy was performed. The results were excellent. The 14 patients treated with laparoscopic cholecystectomy were quickly discharged from the hospital (on an average 4 days after the surgical treatment) and the convalescence period was very short (range 10-15 days). In the patient treated with laparotomic cholecystectomy the postoperatory period was regular.
