AI Article Synopsis
- Radical treatment for gastric cancer involves extensive surgical procedures, but microscopic involvement of the resection line (R1) can worsen prognosis.
- Between 2006-2007, a study on 135 patients showed a 19.25% incidence of R1, primarily in poorly differentiated tumors (G3 and G4), with a significant number exhibiting lymphatic involvement.
- The presence of tumor tissue at the resection line potentially decreases patient survival, suggesting that treatment protocols should consider tumor staging, surgical risks, and patient preferences for further management.
Article Abstract
Introduction: The radical treatment of the gastric cancer consist in large gastric resections and lymphadenectomy. Resection line involvement at microscopic histopathological examination (R1) could change prognostic unfavorable.
Material And Methods: They were 135 patients with gastric cancer operated between 2006-2007, with radical gastric resections and lymphadenectomy. In 3 patients with early gastric cancer and 23 patients with different stages of cancers, histopathological examination showed resection line involvement. From this study were eliminated the patients with stage IV cancers in whom resections were palliative.
Results: Incidence of positive resection line involvement was 19,25%. 88,46% of the tumors were staged pT2 and pT3 and the majority was poorly differentiated or undifferentiated (G3 and G4). Lymphatic involvement (pN1 or pN2) was demonstrated in 18 (69,23%0 patients with R1. Perioperative complications were encountered in 15,38% of this patients, with 7,69% mortality.
Conclusions: Presence of tumoral tissue at resection line level could decrease survival in this patients. Therapeutic protocol in patients with resection line involvement (re-laparotomy with re-resection or surveillance) must be establish in accordance with several factors: T and N category, risks of another surgical interventions, patients acceptance.

Isthmoceles are defects related to Caesarean section (CS) scars, known to cause secondary infertility and interfere with in-vitro fertilization in women who have had Caesarean deliveries. The etiologies are multifactorial. Isthmoceles, similar to dehiscent CS scars, can be potential sites for ectopic pregnancies and abnormal placentation.

Background: Minimally invasive cardiac surgery for mitral regurgitation is challenging in patients with narrow chests due to limited thoracic space. The butterfly technique can prevent systolic anterior motion in patients with degenerative mitral regurgitation and redundant posterior leaflets, but it is difficult to perform via minimally invasive cardiac surgery. Few reports have described mitral valve repair using the butterfly technique or in a narrow chest.

Background: Carinal resection and reconstruction are complex surgical procedures often necessitated by tumors or other pathologies involving the tracheobronchial junction. Traditional approaches to these surgeries are highly invasive. The advent of uniportal video-assisted thoracoscopic surgery (VATS) along with the integration of extracorporeal membrane oxygenation (ECMO) offer potential advantages in reducing surgical trauma and improving outcomes.

Transcranial neurosurgery assisted by endoscopy and intraoperative ultrasound (IOUS) has become an effective approach for real-time visualization and guidance during tumor resection. This study explores the application of these techniques in falcine meningioma (FM) resection, assessing their feasibility and safety. Eleven FM patients underwent transcranial endoscopic resection with IOUS assistance.
