Abstract
Rectal tumor laparoscopic resection is becoming more and more common as a less invasive surgical technique with possible advantages like less discomfort after surgery, shorter hospital stays, and faster recovery periods. This thesis aims to assess the surgical feasibility as well as the outcomes of laparoscopic resection of rectal tumors.
The exploration of laparoscopic surgeries in the context of malignant rectal tumors is a critical endeavour in modern surgical oncology. This thesis delves into the intricate interplay between surgical techniques, patient characteristics, and outcomes in this challenging domain. Beginning with an in-depth examination of rectal anatomy and its vascular supply, the groundwork is laid for understanding the complex nature of rectal cancer pathogenesis. Furthermore, the staging and diagnostic processes are elucidated, offering insights into the multifaceted approach required for effective management.
A thorough review of treatment modalities are highlighted from local excision techniques to systemic chemotherapy regimens, each intervention is evaluated within the broader context of disease management. Surgical approaches, including anterior resection, abdominoperineal resection, and intersphincteric resection, are analyzed in detail, highlighting their respective indications, advantages, and limitations.
The primary aim of the study emerges to assess the feasibility and outcomes of laparoscopic surgery in malignant rectal tumors. A cohort of 20 carefully selected patients forms the basis of this investigation, with strict inclusion and exclusion criteria employed to ensure homogeneity within the sample. Notably, patients above 60 years of age and those with sphincter involvement are excluded, mitigating confounding factors and enabling a more focused analysis.
