RESUMEN
Intra-operative examination of sentinel LN is controversial. Concordance with definitive exam of SLN in this series was 81%, though only 54% of positive cases were diagnosed. Micrometastases and ITC were usually lost intraoperatively, accounting for 14% of cases. Frozen section and touch prep of the SLN were approximately equivalent. The latter has the advantage of preserving tissue for step-analysis of SLN. The ultimate method of intraoperative analysis of SLN which can combine cost-effectiveness and accuracy needs to be determined.

503 patients were retrospectively evaluated to assess whether a previous needle or core biopsy, or surgical surgical excision of the primary tumor are associated with passive dislodgment of tumor cells in the sentinel lymph node, as reported in recent publications. We could not identify any increased incidence of sentinel lymph node micrometastases or isolated tumor cells after diagnostic manipulation of the primary tumor.

Esophageal metastasis from distant primary malignancies is an uncommon occurrence. The first case of a clear cell carcinoma of the kidney metastatic to the esophagus 5 yr after nephrectomy is reported.

BACKGROUND AND STUDY AIMS: Benign anastomotic stenosis (BAS) represents a frequent complication following esophagectomy and cervical esophagogastrostomy for cancer. This study was undertaken to evaluate through early postoperative esophagoscopy the morphologic change of the anastomosis which could be related to BAS development. PATIENTS AND METHODS: Thirty-nine patients who underwent subtotal esophagectomy and cervical esophagogastrostomy were prospectively evaluated. The analyzed factors were: age; sex; the anastomotic size; the presence and number of endoscopically visible stitches; the presence and percentage of mucosal ulcerations involving the anastomotic suture line; the presence of anastomotic leak or dehiscence; the vascularization of the gastric tube; the patency of pylorus. RESULTS: No complications related to the early esophagoscopy were observed. Twelve patients (30.7 %) developed a stenosis postoperatively. The univariate analysis demonstrated anastomotic leak (p < 0.006), more than one endoscopically visible stitch (p < 0.0003), and mucosal ulceration involving more than 50% of the anastomosis (p<0.00009) as factors significantly correlated with BAS development. However stepwise logistic regression extracted the presence of ulcerations involving more than 50% of the anastomosis as the most important independent factor in predicting BAS development (Odds Ratio = 9.03+/-5.5, p = 0.009). All patients who developed a BAS were treated with early pneumatic dilatations, with an 83.3% success rate after a mean of 3.6 sessions. CONCLUSIONS: Early postoperative esophagoscopy seems a safe and effective tool for the monitoring of the anastomosis healing after cervical esophagogastrostomy. The presence of extended mucosal ulcerations appeared as the most important factor in predicting BAS formation.
