RESUMO
OBJECTIVES:: This study sought to determine the clinical and pathological factors associated with perioperative morbidity, mortality and oncological outcomes after multivisceral en bloc resection in patients with colorectal cancer. METHODS:: Between January 2009 and February 2014, 105 patients with primary colorectal cancer selected for multivisceral resection were identified from a prospective database. Clinical and pathological factors, perioperative morbidity and mortality and outcomes were obtained from medical records. Estimated local recurrence and overall survival were compared using the log-rank method, and Cox regression analysis was used to determine the independence of the studied parameters. ClinicalTrials.gov: NCT02859155. RESULTS:: The median age of the patients was 60 (range 23-86) years, 66.7% were female, 80% of tumors were located in the rectum, 11.4% had stage-IV disease, and 54.3% received neoadjuvant chemoradiotherapy. The organs most frequently resected were ovaries and annexes (37%). Additionally, 30.5% of patients received abdominoperineal resection. Invasion of other organs was confirmed histologically in 53.5% of patients, and R0 resection was obtained in 72% of patients. The overall morbidity rate of patients in this study was 37.1%. Ureter resection and intraoperative blood transfusion were independently associated with an increased number of complications. The 30-day postoperative mortality rate was 1.9%. After 27 (range 5-57) months of follow-up, the mortality and local recurrence rates were 23% and 15%, respectively. Positive margins were associated with a higher recurrence rate. Positive margins, lymph node involvement, stage III/IV disease, and stage IV disease alone were associated with lower overall survival rates. On multivariate analysis, the only factor associated with reduced survival was lymph node involvement. CONCLUSIONS:: Multivisceral en bloc resection for primary colorectal cancer can be performed with acceptable rates of morbidity and mortality and may lead to favorable oncological outcomes.

Combined liver and multivisceral resections (CLMVRs) are rare procedures that demand extensive surgical skills. Few reports have discussed the benefit of these complex procedures and their indications are poorly defined. The aim of the present study is to present short- and long-term results of CLMVRs in primary and metastatic malignancies, including a risk analysis for perioperative morbidity and mortality. A review of our prospective surgical database between November 2007 and August 2013 identified 21 patients who had undergone CLMVRs. Preoperative radiologic evaluation and laboratory data, intraoperative results, hospital outcomes, and long-term follow-up were analyzed. CLMVRs were performed due to metastatic disease from different sites in 17 patients, and due to direct local invasion of the liver in the remaining 4 cases. Major hepatectomy was performed in 7 cases. Morbidity was 57% and 90-day postoperative mortality was 9%. Gender and resection of more than 4 organs were found as statistically significant risk factors to develop major complications. Five of 7 patients with 4 or more organs resected presented major complications including mortality (p = 0.026). The overall 1- and 3-year survival rates were 57 and 24%, respectively. Patients undergoing CLMVRs experience acceptable postoperative morbidity and mortality rates. Surgery should be performed only in carefully selected patients, considering their preoperative comorbidities, and in high-volume centers.

BACKGROUND: in Mexico, the management of abdominal penetrating trauma doesn't follow the algorithms of Trauma Center level I, because of our limitations, and laparotomies are inevitable in this context. Is possible use some grade of leukocytosis suspect in-trabdominal lesion? METHODS: study retrospective, descriptive and analytic that inclu-ded patients with abdominal penetrating trauma that suffered exploratory laparotomy. We excluded patients' whit severe damage to soft tissues in extremities, thoracic affection, fractures, or da-mage in nervous system. We divided the patients into 2 groups: group I (therapeutic laparotomy) and group II (non-therapeutic laparotomy). Dependent variables were; age, gender, type of injury, number of lesions, peripheral lesions, time between injury and, from a laboaratory blood sample, leukocytosis mean, percentage of neutrophils, leukocytosis ≥ 12,500 /mm(3), and hemoperitoneum. We compared variables between two groups and use Pearson's χ(2) test and T-Student, and percentages as summary of measures. RESULTS: we included 231 patients, group I with 159 patients and group II with 72 patients. Leukocytosis global was 13.2 mil/mm(3) and neutrophil range of 70.3%. 26% of patients did not have leukocytosis at arrival and evaluation, however they were laparotomized because of present peritoneal irritation. Leukocytosis ≥ 12.5 mil/mm(3) was statistically significant in patients with intrabdominal lesions (74.2% vs 27.7%, p < 0.001). CONCLUSIONS: leukocytosis ≥ 12.5 mil/mm(3) could be an early serum marker abdominal penetrating trauma.

BACKGROUND: The abdomen ranks in third place of body areas injured by trauma. Evaluation and stabilization of these patients form the cornerstone in emergency medicine. Diagnostic approach and treatment outcome are influenced by several factors. Injury mechanism and pattern vary according to geography and there is an association with drugs and alcohol. Physical examination remains the most reliable indicator for surgery. Associated injuries are present in up to 26% of cases. We undertook this study to determine penetrating abdominal trauma incidence and frequency, demographic factors, rate of immediate and delayed laparotomies, and associated complications as well as to define the usefulness of penetrating abdominal trauma index (PATI). METHODS: An observational, prospective, longitudinal descriptive study was carried out at the Hospital Central "Ignacio Morones Prieto," San Luis Potosi, Mexico from January 1, 2005 to December 31, 2005 on patients who underwent exploratory laparotomy for penetrating abdominal trauma. Twenty one variables were studied. Basic statistical analysis, ANOVA, chi(2) and Student's t-test were used. RESULTS: Of the 79 patients who were included, 93.67% were males. The third decade of life was the most affected, with a night presentation being predominant as a result of personal violence. Drug use was observed in 50.6%; stab wounds in 63.3%. The most frequent locations were the left upper and right lower quadrants and epigastrium; solitary wounds were predominant. Associated injuries were most common in the thorax and limbs. Of the laparotomies performed, 92.4% were urgent and 60.53% were therapeutic; 15.19% required reoperations; complications were observed in 39.24%; and mortality rate was 3.9%. CONCLUSIONS: Due to high non-therapeutic and negative laparotomies rates, a more selective approach is needed, including repetitive physical examination and the appropriate use of auxiliary diagnostic studies.
