ABSTRACT
BACKGROUND: With term GIST is now defined a group of mesenchimal tumours of the gastrointestinal tract expressing immunopositivity for kit protein kinase (CD117). Surgical therapy remains the gold standard for these rare tumours. Imatinib Mesylate (STI-571) is a potent inhibitor of Kit Kinase activity and different reports demonstrated its efficacy in unresectable or metastatic Gists. AIM OF THE PAPER: To value the incidence of GISTs among gastric mesenchimal neoplasms and analyzed their clinical presentation, prognostic parameters and surgical treatment. The response to Imatinib Mesylate in a case of metastatic GIST is then valued. METHODS: Twelve cases of gastric mesenchimal neoplasms are retrospectively reviewed and tested by CD117 immmunopositivity identifyng 8 GISTs. The median follow-up was 37 (range7-120) months. We describe in details the case of a metastatic Gist treated for 15 months with Imatinib Mesylate. RESULTS: The 67 per cent of mesenchimal gastric tumours were CD117+. Gastrointestinal bleeding was the most common presenting symptom. The 50% of patiens with malignant GISTS had a palpable abdominal mass at diagnosis. All tumors < 5 cm in diameter had a mitotic count (MC) <5/50 high-power fields (HPFs) except a case of high grade leiomyosarcoma. Surgical therapy was complete tumour resection with free margins. No recurrence was observed in lesions <5cm and < 5 mitosis/50 High Power Fields (HPFs). A good response to Imatinib Mesylate was reported in a metastatic GIST. CONCLUSION: The surgeon's role in gastric Gist's treatment is to achieve a complete cancer resection with free margins. In advanced lesions, even in presence of hepatic metastases, surgical resection of the mass is indicated because is possible to obtain a stabilization or a partial remission with Imatinib Mesylate palliative treatment in some patients.

OBJECTIVES: Necrotizing fasciitis is a challenging and potentially lethal disease; early diagnosis is of paramount importance and aggressive multidisciplinary treatment is mandatory. Overall mortality rates of 33-73% have been reported. The aim of this study was to report the experience with necrotizing fasciitis of an emergency surgery department. METHODS: From October 1995 to December 2001 we observed 11 cases of necrotizing fasciitis. The patients were five men and six women, with ages ranging from 33 to 80 years. RESULTS: Triggering aetiological factors were found in eight cases. In all patients a multidisciplinary approach was utilized. Every patient had a daily surgical debridement of the necrotic areas in the operating room. Polyantibiotic therapy was performed, and was changed according to culture results. After surgery, nine patients were submitted to hyperbaric oxygen therapy. Seven deaths (63.6%) were observed: two cases of pulmonary embolism and five cases of septic shock. Four patients survived; three had a complete recovery with progressive healing of the wounds, whereas one patient had severe impairment of the motility of the affected hand. The mean interval between the onset of symptoms and hospital admission was 5.4 days; for patients who ultimately died it was 7.3 days, whereas for patients who ultimately survived it was 2 days (P<0.05); moreover these patients were significantly younger than those who died (P<0.05). CONCLUSION: The treatment for necrotizing fasciitis is a combination of surgical debridement, appropriate antibiotics and optimal oxygenation of the infected tissues. However, the mortality for this disease is quite high, and is related to late diagnosis and advanced age. Necrotizing fasciitis must be considered a true dramatic surgical emergency.

PURPOSE: Sutured and stapled intestinal anastomoses are perceived to be equally safe in elective intestinal surgery. However, our search of the literature failed to find any studies comparing hand-sewn and mechanical anastomoses in emergency intestinal surgery. Thus, we compared the short-term outcomes of patients with sutured as opposed to stapled anastomoses in emergency intestinal surgery. METHODS: Between 1995 and 2001, 201 patients underwent emergency intestinal operations at the Department of Emergency Surgery of Sant'Orsola-Malpighi University Hospital. The outcomes of patients with sutured and stapled anastomoses were compared in a prospective analysis. Patients were randomly divided into a stapled group (106 anastomoses) with anastomoses made using linear and circular staplers, and a hand-sewn group (95 anastomoses) with anastomoses made by double-layer suturing. RESULTS: There were no significant differences between the groups in operative indications or other parameters. The operation times in the stapled group were significantly shorter than those in the hand-sewn group (P < 0.05), but there were no significant differences in anastomotic leak rates, morbidity, or postoperative mortality between the two groups. CONCLUSIONS: In emergency intestinal surgery comparable results can be achieved using mechanical and manual anastomoses.
