[Role of anastomotic configuration in ileocolic resection for Crohn's disease]. / Ruolo della configurazione anastomotica nella resezione ileocolica per malattia di Crohn.

Crohn's disease is characterised by a high incidence of perianastomotic recurrence after ileocolic resection. The influence of the anastomotic configuration on the incidence of reoperation was evaluated in patients undergoing resection for Crohn's disease. In our Institution, from 1993 to 2007, 308 consecutive patients affected by ileocolic Crohn's disease were submitted to 343 ileocolic resections or right colectomies. In 292 cases (85.1%), an antiperistaltic side-to-side (or functional end-to-end) anastomosis was performed, with an 80 mm linear stapler in 190 cases, a 100 mm linear stapler in 79, and a hand-sewn anastomosis in 23. The other hand-sewn anastomotic configurations were: 30 (8.8%) side-to-side isoperistaltic, 15 (4.3%) end-to-side and 6 (1.8%) end-to-end. The overall morbidity was 7.3%, with two postoperative deaths (0.6%) with no significant differences between groups. There were 38 overall recurrences (11%). In the side-to-side antiperistaltic group, the rate of recurrence was 8.2%, significantly lower than the recurrence rates observed in the other anastomoses (26.9%, p = 0.002), especially side-to-side isoperistaltic anastomosis (33.3%, p = 0.001). Early recurrences (< 1-year) were 2.6%, without significant differences between groups. There was a higher trend for end-to-end anastomosis (16.6%). In the side-to-side antiperistaltic group the morbidity was higher in the large mechanical anastomoses (100 mm length), but the recurrence rate was lower in this group as compared to the 80 mm anastomoses (1.2% vs. 12.1%, p = 0.006). Our non-randomised study suggests a better trend for the wide side-to-side antiperistaltic technique in terms of recurrence rate. These observations need further investigation with randomised controlled trials to compare the different anastomotic procedures.

Locally advanced leiomyosarcoma of the spleen. A case report and review of the literature.

BACKGROUND: Leiomyosarcomas are rare tumours, predominantly localized in the stomach, small intestine and retroperitoneum. Only one case of primary leiomyosarcoma of the spleen is described in human beings in literature. CASE PRESENTATION: We report a case of locally advanced primary leiomyosarcoma of the spleen in a 54 year-old woman, diagnosed only after splenectomy, performed with the suspicion of splenic haematoma. CONCLUSION: Due to the lack of cases, no specific chemotherapy regimen has been tested to provide a longer survival.

Small periampullary duodenal gastrointestinal stromal tumor treated by local excision: report of a case.

Gastrointestinal stromal tumors (GIST) are mainly located in the stomach and the small bowel, with the duodenum accounting for about 4%. We report the case of a 66-year-old woman with a periampullary GIST of the duodenum that was treated by local excision and direct duodenal wall defect repair. Since no definitive clinical criteria have been established to differentiate malignant from benign mesenchymal tumors, preoperative cytology was not available and surgical removal of the 3.5 cm tumor was feasible, the patient was treated conservatively. The morbidity and mortality rates of the more radical and invasive duodenopancreatectomy, in particular when dealing with a soft pancreatic stump with a narrow pancreatic duct, are, in our opinion, too high for a potentially benign disease when the more conservative procedure is feasible. Four years after surgery the patient is doing well and control CT scan showed the absence of local recurrence.
