The analysis is based on an analytical systematization of contemporary Russian and international literature. The article also substantiates the need for a unified classification of surgical techniques according to the level of operative morbidity. A broad body of contemporary publications on gastric surgery was analyzed. The literature addressed the extent of operative procedures and the structure of perioperative complications. The analyzed sources included clinical studies, national and international registries, systematic reviews, meta-analyses, as well as international and national clinical guidelines reflecting current surgical practice. The analysis demonstrates that a stepwise increase in the extent of gastric resection is associated with higher operative morbidity. This is accompanied by an increased risk of perioperative complications, including severe complications (Clavien–Dindo ≥IIIB). The absence of a standardized system for stratifying gastric surgical procedures according to operative trauma limits risk prediction and the comparability of outcomes. The proposed four-level classification of surgical interventions (I–IV with sublevels IVA and IVB), based on objective criteria including the extent of resection, involvement of adjacent anatomical structures, and complexity of the reconstructive stage, enables systematic stratification of procedures according to the degree of surgical trauma and may be applied for perioperative risk assessment, optimization of surgical planning, and analysis of treatment outcomes and results.</p></abstract><trans-abstract xml:lang="ru"><p>Целью настоящей работы является представление авторской концепции стратификации объёма хирургических вмешательств при плановом лечении заболеваний желудка как фактора риска периоперационных осложнений. В работе проанализированы современные публикации, посвящённые хирургическому лечению заболеваний желудка, объёму оперативных вмешательств и структуре периоперационных осложнений. В анализ включены клинические исследования, национальные и международные регистры, систематические обзоры, метаанализы, а также международные и отечественные клинические рекомендации, отражающие актуальные подходы к хирургическому лечению. Проведённая аналитическая систематизация данных демонстрирует, что последовательное увеличение объёма резекции желудка закономерно сопровождается ростом операционной травматичности и повышением риска периоперационных осложнений, включая тяжёлые осложнения (степень ≥IIIB по классификации Clavien–Dindo). Отсутствие стандартизированной системы стратификации операций на желудке по уровню операционной травмы ограничивает возможности прогнозирования рисков и сопоставления результатов лечения. Предлагаемая нами четырёхуровневая классификация хирургических вмешательств (I–IV с подуровнями IVA и IVB), основана на объективных критериях объёма резекции, вовлечения смежных анатомических структур и сложности реконструктивного этапа, позволяет системно ранжировать операции по уровню хирургической травматичности и может быть использована для оценки периоперационного риска, оптимизации хирургического планирования и анализа результатов и исходов лечения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>gastric cancer</kwd><kwd>risk stratification</kwd><kwd>surgical classification</kwd><kwd>extent of resection</kwd><kwd>perioperative complications</kwd><kwd>surgical trauma</kwd><kwd>author’s perspective</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак желудка</kwd><kwd>стратификация риска</kwd><kwd>хирургическая классификация</kwd><kwd>объём резекции</kwd><kwd>периоперационные осложнения</kwd><kwd>операционная травматичность</kwd><kwd>авторская точка зрения</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>International Agency for Research on Cancer [Internet].
