Laparoscopy — Minimally Invasive Surgery

Laparoscopy, frequently referred to as keyhole surgery, involves inflating the abdominal cavity with medical-grade carbon dioxide gas to create a visualised working space. The surgeon then introduces a laparoscope—a slender, lighted telescope equipped with a high-definition video camera—through a puncture wound measuring roughly five to ten millimetres. High-resolution images are projected onto operating theatre monitors in real time, granting an illuminated, magnified view of peritoneal surfaces and organs.

Additional tiny incisions permit the insertion of delicate instruments capable of grasping, dissecting, cutting, or coagulating tissue. In modern oncology, laparoscopy serves dual purposes: diagnostic staging, where hidden peritoneal spread or liver metastases can be identified directly before extensive treatment begins, and therapeutic intervention, in which entire tumours, regional lymph node basins, or affected organs are safely removed.

In oncological care, accurate staging determines the trajectory of your entire treatment plan. Staging laparoscopy often detects minute tumour deposits on abdominal linings that even sophisticated PET or CT scans fail to visualise. Finding these early prevents unnecessary major operations that would not cure the disease, redirecting care toward effective systemic therapies like chemotherapy instead. When laparoscopy is used for curative tumour resection, its reduced physical impact helps patients preserve physical stamina and recover rapidly. This faster recuperation ensures that any necessary follow-up treatments, such as post-operative adjuvant chemotherapy, begin without harmful delays.

Before laparoscopy, patients undergo cross-sectional imaging, including contrast-enhanced CT, MRI, or PET scans, to map disease targets. During the procedure itself, surgeons collect suspicious tissue samples for histopathology and draw peritoneal washings to test for microscopic cancer cells via cytology. Tumour tissues obtained laparoscopically are evaluated for critical biomarkers such as HER2 status, mismatch repair deficiency (dMMR), or microsatellite instability (MSI).

Laparoscopy is routinely utilised in gastrointestinal and gynaecological cancers. It plays a critical staging role in gastric cancer, pancreatic ductal adenocarcinoma, and oesophageal malignancies to rule out occult peritoneal spread. For therapeutic resection, laparoscopy is a primary surgical approach for colorectal cancer, endometrial cancer, early-stage cervical cancer, and ovarian tumours. It is also used in urological oncology, particularly for kidney and prostate resections.

Findings from a diagnostic laparoscopy fundamentally guide therapy. If extensive peritoneal metastases are uncovered, plans for immediate radical surgery are replaced by systemic chemotherapy or immunotherapies. Conversely, if disease is strictly localised, complete laparoscopic resection or cytoreductive surgery proceeds. Post-procedure recovery is typically swift, enabling patients to proceed with planned adjuvant chemotherapy or radiation therapy weeks sooner than after open surgery.
