PurposeSurgical intestinal resection margins in colon cancer are a longstanding debate in terms the optimal distance between the tumor and the colonic section line. The aim of this study is to define the oncological outcomes in relation to surgical margins, measured in terms or recurrence rate, time-to-recurrence, disease-free survival and overall survival in a population of node negative colon cancer patients.MethodsWe conducted a retrospective observational longitudinal single institution study. All patients submitted to colon cancer surgery between January 2006 and December 2010 were analyzed. Only node negative patients were included in the study, with analysis of 215 patient charts, divided in two groups (Intestinal margin lower than 5 cm—group 1; and 5 cm or higher—group 2).ResultsMean age of patients was 70.4 years (±11.7), with a male predominance (57.7%). Group 2 more frequently corresponded to Stage II (83 vs 71%; p = 0.05). Global mean total lymph nodes harvested were 12, and were higher in group II than in group I (13.8 ± 8.2 vs 10.4 ± 5.7; p = 0.001). In terms of time-to-recurrence patients of group 2 had longer time than patients of group 1 (32.3 ± 12.1 vs 21.8 ± 13.8 months; p = 0.03), as well as a lower recurrence rate in group I (13.7 vs 17.2%), despite not statistically significant.ConclusionsThis study has showed that patients with 5 cm or higher bowel resection margins had longer time-to-recurrence that was statistically significant. Recurrence rates were lower in the group of patients with longer surgical margins, however not statistically significant.
The incidence of internal hernias is rare (0.2–0.9%). The prevalence of intestinal obstruction for an internal hernia is low (0.5–5%), however if strangulation is present the overall mortality is higher than 50%. There are multiple places where an internal hernia may be localized, with transmesenteric: transmesocolic (8%) and transomental (1–4%) as the rarest. We report a series of two cases (men with 40 years-old and women with 92 years old) of volvulus of colon sigmoid in a strangulated transverse and descendent transmesocolic hernia, with one case associated also to a transomental hernia. Both patients were submitted to a Hartmann procedure and on follow-up remained free of complains. In conclusion, transmesenteric internal hernia should be included as diagnosis hypothesis for intestinal occlusion and if the diagnosis is made, the patient should be submitted to emergency surgery due to high rates of complications, high morbidity and mortality.
Specificity of MDCT in the stratification of patients for neoadjuvant therapy may be high enough to prevent overtreatment. However, it may lead to undertreatment in a meaningful proportion of patients. Observer performance may benefit from targeted training programs, given the variability and observer dependence of the results. Limitations include 4-slice MDCT equipment, time to surgery and lack of long-term outcome information based on imaging parameters per se.
Highlights
Proper drainage of supralevantor abscess should be achieved for the fistulae path.
After supralevator abscess resolution the drain should be taken off and marsupialization with ENDO GIA® should be performed.
It is possible to adapt the length of ENDO GIA® to the length of the fistulae tract.
This treatment is a safe method for definitive treatment of traumatic supralevator abscess with intersphincteric fistulae.
Splenic cysts are rare clinic entities. Non-parasitic cysts are the most frequent cystic lesions of the spleen. In the last decade acknowledgment of the importance of the spleen function, along with development of imaging methods and surgery technics, allowed a conservative approach to be increasingly considered as the best approach in splenic cysts treatment. We present the case of a 34-year-old woman with an asymptomatic simple splenic cyst in the upper pole incidentally diagnosed in a thoracic CT. A laparoscopic upper pole splenectomy was performed on the patient, with no complications. Despite the rareness of this procedure and the fact that it was used in a simple splenic cyst, this article emphasises the idea that this approach is safe, reproducible and advantageous for the patient.
