Host-related predictive factors for anastomotic leakage following large bowel resections for colorectal cancer.

AIM: To identify the risk, the host-related prognostic factors and their predictive value for anastomotic leakage after colorectal resections following cancer. METHOD: 993 patients who underwent large bowel resection and primary anastomosis above 12 centimeters from the anal verge, without a temporary or permanent stoma at the Surgical Hospital No.3 (Cluj-Napoca, Romania) were retrospectively reviewed. RESULTS: 32 (3.22 percent) anastomotic leaks were confirmed. Univariate analysis showed that the preoperative variables significantly associated with anastomotic leakage included: weight loss, smoking, cardiovascular disease, lung disease, hypoproteinemia, diabetes, anemia, leukocytosis, presence of two or more underlying diseases. Alcohol use, cerebrovascular disease, bowel preparation, type of anastomosis, tumor location, stage and histology were not significant variables. Hypoproteinemia (total serum protein level < or = 6 g/dl) and anemia (serum hemoglobin level < or = 11 g/dl) remained significant in the logistic regression model. The prognostic role of serum hemoglobin and proteins for the anastomotic leak was assessed using ROC curve analysis. For the cut-off value of serum protein level = 5.5 g/dl, a sensitivity of 61.6 percent and a specificity of 84.2 percent were calculated. The area under the curve was 0.703 (p= 0.0024). The area under the curve for serum hemoglobin was 0.616 (p=0.028). A sensitivity of 64.0 percent and a specificity of 64.7 per cent were obtained for a cut-off value of 9.4 g/dl. CONCLUSION. A serum protein level lower than 5.5 g/dl and serum hemoglobin lower than 9.4 g/dl could be considered as host-related predictive markers for anastomotic leak in large bowel resections for cancer.

PURPOSE: We analyzed the clinical results of different techniques of resection for malignant colorectal (primary or staged) obstruction. METHODS: The subjects of this retrospective nonrandomized clinical study were 165 patients with malignant colorectal occlusion who underwent surgery treatment in our Department between 2002-2006. Patients with peritonitis or treated by means of permanent colostomy, palliative anastomosis, primary Hartman resection and rectal excision were excluded. RESULTS: Patients with large bowel obstruction caused by obstructive malignant colorectal lesions underwent either one-stage primary resection with anastomosis (77 patients) or staged interventions (88 patients). There were no differences in age, sex, comorbidities, tumor staging, serum preoperative levels of hemoglobin and proteins between the two groups of patients defined by the different surgical techniques. Regarding mortality and morbidity following surgical treatment for large bowel obstruction no significant difference among the two groups (p > 0.05) or the fistula rate (p = 0.435) was obtained. Moreover, results showed a higher incidence of mortality (11.8% vs 7.8%), morbidity (13.6 vs 10.4) and increased hospitalization period (p = 0.03) among the patients that undergone series resections. CONCLUSIONS: One stage primary resections with anastomosis of the large bowel can be performed safely in case of emergency whenever patient comorbidities and local conditions do not stand as major restrictions.

Bouveret syndrome associated with acute gangrenous cholecystitis.

An 89-year-old patient was hospitalized with signs of acute lithiasic cholecystitis and gastric emptying failure. The decision for surgery was taken and a subhepatic block was evidenced, caused by a perforated gangrenous cholecystitis with pericholecystic abscess, a cholecysto-antroduodenal fistula with two gallstones, 9/5 and 4/3 cm in size, impacted in the duodenum. It was necessary to perform an Y-en-Roux antroduodenojejunal anastomosis because an antroduodenal parietal defect resulted after the removal of the gangrenous gallbladder. The immediate and long term postoperative evolution in terms of anastomosis functionality was good.

Survival prognostic factors in patients with resection of liver metastasis from colorectal cancer.

BACKGROUND AND AIM: Case selection criteria for resection of liver metastasis after colorectal cancer are still incompletely elucidated and represent a subject of great interest recently. Our aim was to evaluate 2-year survival after resection and to identify the survival risk and prediction factors in those cases. METHODS: 63 patients diagnosed and undergoing liver resection for colorectal metastatic disease to the liver at the Surgical University Hospital No.3 (Cluj-Napoca, Romania) between 01.01.2002 and 31.12.2005 were included in the study. Exclusion criteria were: palliative treatment as well as surgical treatment performed in a different surgical centre. After the surgical treatment, patients were followed regularly using clinical assessment on a 3 monthly basis with abdominopelvic ultrasound or computerised tomography annually. The following variables were recorded: age, gender, coexisting medical diseases, blood tests results, tumour site, maximal tumour diameter after resection, duration of surgery, surgical procedure and the clinical outcome until last follow-up, including date of death where appropriate. RESULTS: 2-year post-operative survival was 65.1%. In univariate analysis: age (< 65 vs > = 65 years, p = 0.041), metastasis number (< 3 vs > = 3 tumors, p = 0.049), maximal tumor dimension (< 3 vs > = 3 cm, p = 0.047), glutamine-oxaloacetic transaminase (GOT) preoperative level (< 42 vs > = 42 mg/dl, p = 0.018) were significant factors correlated to median survival time. However, non of the above mentioned factors presented independent prediction power in multivariate analysis (Cox regression, p < 0.05). CONCLUSIONS: Our results support liver metastasis resection without prior case selection except for technically-operative criteria selection.
