RFA has still to be confirmed as an alternative to surgery for potentially-resectable HCCs.

The aim of this multicenter longitudinal study was to evaluate the pattern of recurrence in patients submitted to potentially curative surgery for intestinal-type and diffuse-type gastric cancer. The study included 412 patients surgically treated at three Italian surgical departments, subdivided into 273 intestinal-type cases (group A) and 139 diffuse-type cases (group B). Recurrence of disease was found in 41% of group A cases and 65% of group B cases (p < 0.0001). The incidence of locoregional, hematogenous, and peritoneal recurrence was 20%, 19%, and 9% in group A, and 27%, 16%, and 34% in group B, respectively; the difference between the two groups was statistically significant for peritoneal recurrence (p < 0.0001). Multivariate analysis identified as prognostic variables lymph node status, depth of invasion, extent of lymphadenectomy, advanced age, and male gender in group A; depth of invasion, extent of lymphadenectomy, tumor size, and lymph node status, in group B. Whereas in group A the incidence of peritoneal recurrence was limited in all subgroups examined, in group B very high rates were observed in cases with infiltration of the serosa, involvement of second-level lymph nodes, or large tumor size. The notable difference in the risk of peritoneal recurrence between the intestinal and diffuse types should be taken into consideration in the therapeutic approach to gastric cancer.

A lower feasibility of laparoscopic cholecystectomy has been found for severe cholecystitis. A lower threshold of conversion is recommended since this may allow to reduce local postoperative complications. Literature data lack valuable comparative studies with other treatment modalities, which therefore need to be investigated.

This study demonstrates that the proposed prognostic score, which is easily obtained after emergency endoscopy, is useful in clinical practice because it can identify patients with different levels of rebleeding risk. It can be helpful in patient management and decision making for discharge.
