The document summarizes 4 cases of minimally invasive surgery for gastrointestinal cancer. It describes a 70-year-old male with advanced distal gastric cancer who underwent palliative distal gastric resection with Billroth reconstruction. Post-operatively, the patient had an uneventful recovery with no further obstruction or bleeding after 6 months, though he remained cachexic. The histopathology found a poorly differentiated adenocarcinoma that was T3, though there was no comment on lymph nodes. In total, the document reviews 4 brief case studies.
