ABSTRACT
OBJECTIVE: To study was to investigate the associated morbidity and mortality of the restoration of intestinal continuity after Hartmann's procedure. METHODS: Hospital records of 29 patients undergoing surgery to restoration of intestinal continuity after Hartmann's procedure at Hospital das Clínicas da Universidade Federal de Minas Gerais between January 1998 and December 2006 were retrospectively analyzed. Demographic, morbidity and mortality data were colleted. RESULTS: There were 16 men and 13 women with mean age of 52.6 years. The median time between the Hartmann's procedure and the attempt of closure of colostomy was 17.6 months (range,1-84 months). The median operation time was 300 minutes (range, 180-720 min). The restoration of the continuity was successful in 27 patients (93%). Two patients had anastomotic leakage (7%) and 7 had wound infection (22%). The mortality rate was of 3.4% (1/29 patients). There were association between unsuccessful restoration of intestinal continuity and previous attempt of closure (p=.007), chemotherapy (p=.037) and long term stay with colostomy (p =.007). CONCLUSION: The interval between the Hartmann's procedure and the restoration of intestinal continuity should not be long. The patients should be aware that in some circumstances the restoration of intestinal continuity after Hartmann's procedure is not possible due to local conditions of the rectum.

Scorpion venom (TX) promotes gastric acid and pepsin secretion leading to acute gastric mucosal lesions (AGML), when injected in animals. The goal of the present study was to observe the effects of acid gastric secretion blockers over the incidence of TX-induced AGML in vivo. To verify this model, we used male albino rats, fasted 18-20 h (n=122) and anaesthetized with urethane (1.4 g/kg, i.p.). Their trachea and left femoral vein were both cannulated; the first to avoid airway obstructions during scorpion intoxication and the second for administration of saline, TX and acid blockers. Following the surgical procedure, the animals were divided in 10 groups of at least 10 animals each. Control groups were injected with NaCl 0.9% 1 ml/kg (n=10) or TX 375 microg/kg (n=32). Test groups (n=10, each) received atropine 5 mg/kg, cimetidine 10mg/kg, ranitidine 2.5mg/kg, ranitidine 5mg/kg, omeprazol 1 mg/kg, omeprazol 4 mg/kg, octreotide 80 and octreotide 100 microg/kg 10 min before the TX was injected. After 1h of intoxication, the stomach was resected for macroscopic study and the gastric secretion was collected for volume, pH and acid output assessment. We observed that all blockers were able to completely or partially prevent the TX-induced acid secretion as well as the AGML (p<0.05). Our data suggest the TX-induced AGML can be prevented by different class of acid blockers injected before the intoxication.
