Lymph node assessment in colorectal cancer surgery: laparoscopic versus open techniques.

AIM: The aim of our study is to compare the outcomes of laparoscopic resection (LR) and open resection (OR) for colorectal cancer surgery evaluating lymph node assessment. It may be important to remove and examine an adequate number of lymph nodes because a more extensive nodal resection has been associated to higher survival rate and lower recurrences. PATIENTS AND METHODS: 150 patients (74 females and 76 males) with colorectal cancer were enrolled and analyzed from January 2006 to March 2010 in our Unit. 100 procedures were performed with traditional laparotomy and 50 procedures laparoscopically. A strict follow-up was scheduled every 1-3-6 months after surgery and, therefore, every year. RESULTS: Laparoscopic techniques require a longer operating time. 2484 total lymph nodes examined with a mean of 16,56 removed per resection in all procedures. 1632 lymph nodes were removed during open procedures and 852 removed during laparoscopy. The scheduled follow-up demonstrated that local recurrence and distant metastasis presented with no significant differences between two groups and overall survival and disease-free survival were assessed over 5 year in 80% of patients. CONCLUSIONS: According to our experience, laparoscopic colorectal surgery is safe and feasible, with better short-term outcomes and oncological adequacy comparable to open approach.

[Point-of-care ultrasound in emergency department : a case report of acute dyspnea during pregnancy]. / Apport de l'échographie thoracique aux urgences : à propos d'un cas de dyspnée aiguë durant la grossesse : cas clinique.

On the basis of the case report of a pregnant woman with acute pleuritis, this article describes the diagnostic modalities of dyspnea during pregnancy. The utility and effectiveness of bedside ultrasound examination by the emergency physician («POCUS¼) are reviewed in view of recent literature data. The ultrasound in this case is considered to be the extension of physical examination aiming at providing answers with immediate clinical relevance.

Au départ du cas clinique d'une femme enceinte présentant une pleurésie, cet article détaille la mise au point d'une dyspnée durant la grossesse. L'utilité et l'efficacité d'un examen échographique pulmonaire par l'urgentiste au chevet du malade («POCUS¼) sont revues à la lumière des données récentes de la littérature. L'échographie dans ce cas est un parfait prolongement de l'examen clinique et vise à apporter des réponses dont l'intérêt clinique est immédiat.

Colorectal retained foreign bodies per anum introduced. Three years retrospective study at Emergency Surgery Unit.

Colorectal foreign bodies per annum introduced are not exceptional. They can be classified as high-lying or low-lying, depending on their location relative to the recto-sigmoid junction. High-lying rectal foreign bodies sometimes require surgery; low-lying ones are often palpable by digital examination and can removed at bedside. No reliable data exist regarding the frequency of inserted rectal foreign bodies and the literature is largely anecdotal. We review our experience on patients almost all males and heterosexual with retained colorectal foreign bodies and their outcome in Surgical Emergency Unit of a Southern Italy University hospital.

Analysis of prognostic factors for the indication of central lymphadenectomy in papillary thyroid carcinomas.

BACKGROUND: In this study we examined whether it was possible following preoperative parameters statistically significant correlation with the presence of metastatic lymph nodes in the papillary thyroid carcinoma. We conducted a retrospective study in a group of patients with a preoperative diagnosis of papillary carcinoma who underwent total thyroidectomy associated with routine lymphadenectomy of the central compartment (level VI). PATIENTS AND METHODS: The study group consisted of patients whose definitive histological lymph node examination was positive for metastasis (N1), and the control group comprised patients found negative for metastasis (N0). RESULTS: Tumour diameter had a significance at 10% level [Pr(>|z|): 0.056], thus indicating that increased tumour size results in a higher probability of being in group N1. The logistic regression revealed that variables with a significance at 5% level for the presence of metastatic lymph nodes in the central compartment (N1) were: sex [Pr(>|z|): 0.019], overall patient age [Pr(>|z|): 0.012] and age >45 [Pr(>|z|): 0.022]. We performed a statistical analysis with the association of three preoperative variables (presence of ultrasound-revealed microcalcifications, presence of solid hypoechogenic nodule and type III vascularisation on echocolour-Doppler); this was found to result in a highly significant probability of entering into group N1. CONCLUSIONS: We found variables statistically significant for the presence of metastatic central compartment lymph nodes, including female sex, age >45 yrs and tumour diameter >1.5 cm. The association of papillary carcinoma with microcalcifications, solid hypoechogenic nodule structure and type III vascularisation on echocolour-Doppler also resulted in a statistically significant increase in the probability of positive level VI lymph nodes.
