Our initial results suggest that the reported technique is safe and satisfies the oncological principles. It provides the advantages of minimally invasive surgery by overcoming some limitations of conventional thoracoscopy.

Simple closure followed by Helicobacter pylori (Hp) eradication has become the most used procedure in perforated ulcer treatment. However, its efficacy and safety are still to be determined. To assess recurrence and re-perforation rates, and as a secondary objective, to analyze Hp infection rates in perforated ulcer patients and controls, we conducted a prospective study. Ninety-two consecutive patients (ages: 19-96 years) were operated on between 1996 and 2002, and treated by simple closure followed by Hp eradication and NSAID avoidance. The data were prospectively collected in a database. Hp infection was diagnosed in 68 patients (73.9%). Thirty-four patients (37%) consumed nonsteroidal anti-inflammatory drugs (NSAIDs), and 23 (25%) had both Hp infection and NSAID antecedents. The perforation was gastric in 4 cases and pre-pyloric, pyloric or duodenal in 88. There were postoperative complications in 24 patients (26%) and 4 patients died (4.3%). Hp eradication was shown in 46 patients. There was clinical ulcer recurrence in 4 (4.3%); in 3 of them recurrence manifested as re-perforation, all in gastric locations. Overall relapse and re-perforation 1-year crude rates were 6.1% and 4.1%, respectively. Crude rates for non-gastric ulcer recurrence were 0 at 1 year and 2.6% at 2 years and for non-gastric ulcer re-perforation rates were 0 at 1 and 2 years. This therapeutic strategy is associated with a low rate of recurrence and no re-perforations in case of duodenal, pyloric, or pre-pyloric perforated ulcers, but it is not acceptable for perforated gastric ulcers.

Objective: to analyze the results of our series in order to assess whether surgical excision is still a valid therapeutic option in case the patient needs surgery. Secondarily, to analyze Helicobacter pylori infection rate. Patients and method: a retrospective study of 69 consecutive patients having stage I E-II E primary gastric lymphoma; of these, 65 were treated by gastrectomy between 1974 and 1999. Mean age: 62.6 years (28-85). New staining of paraffin-embedded samples from the surgical specimen were carried out (hematoxiline-eosine, Giemsa, immunohistochemistry) and reviewed. The histological classification was performed according to Isaacson's criteria. The statistical analysis was done by Chi-squared and Fisher's exact tests, as well as Kaplan-Meier and Log-Rank tests. Results: mortality was 9.2%. There were non-fatal complications in 10.8%. Helicobacter pylori was identified in 62.7%. Seven patients (11.9%) suffered a relapse. The 5-year survival probability was 87%. The statistical analysis did not show any influences of Ann Arbor stage, gastric wall invasion, Helicobacter pylori infection, histological type, or margin resection involvement on survival. Conclusions: surgical excision provides a high rate of complete remissions and excellent long-term survival with acceptable mortality. Therefore it appears to be a valid treatment in case of emergency surgery, incidental finding, or lack of histological diagnosis.
