Single-port Laparoscopic Liver Resection in Patients with Previous Abdominal Surgeries: Is it a Feasible Approach?

Single-port laparoscopic liver surgery has become an attractive procedure for many surgeons in order to decrease surgical aggression and the complications related to laparoscopic ports. The aim of this study is to assess the feasibility and efficacy of single-port laparoscopic liver resections in patients with previous upper or lower abdominal surgery. A series of ten patients with history of previous abdominal surgery who underwent single-port laparoscopic surgery for liver metastases, primary liver cancer or benign hepatic tumor, is being presented here.

[Gastric adenocarcinoma in Zinsser-Cole-Engman syndrome].

Zinsser-Cole-Engman syndrome is a congenital dyskeratosis that produces cutaneus and hematologic alterations and, in 5% of patients, gastrointestinal neoplasms. We report the case of a 37-year-old man with this syndrome who was diagnosed with gastric adenocarcinoma. This case provides an example of the management that should be followed with these patients in order to identify neoplasms at stages in which treatment is curative.

Factors of prognostic value in long-term survival of colorectal cancer patients.

We have studied 191 protocolized colorectal cancer patients, analyzing the prognostic factors described in the literature as being important to long-term survival. Of the data studied, sex, age, duration of symptoms, tumor location, tumor extension within the circumference of the bowel lumen, and the surgical technique employed, all showed differences in terms of five-year survival, but without reaching statistical significance. The factors with statistically significant prognostic value were first symptoms, occlusion, perforation, primary tumor size and configuration, lymph node involvement, degree of wall infiltration, presence of emboli, degree of differentiation and Scarff index.
