“In cases of ordinary exploratory operation for carcinoma, before having recourse to the usual large incision, the cystoscope is introduced through a very small and relatively unimportant incision, possibly made with cocaine, may reveal general metastases or a secondary nodule in the liver, thus rendering further procedures unnecessary and saving the patient a rather prolonged convalescence”.

Preoperative Staging and Assessment of Resectability of Pancreatic Cancer

Results
• Overall resectability 33/88 (38%)
• Laparoscopy found metastatic disease when present in 22/23 patients (96%)
• Laparoscopy found no metastatic disease in 24/24 patients (100%)

Conclusion
• Laparoscopy is particularly sensitive for detecting small metastases (96%)
• This approach to pancreatic cancer allows the elimination of some operations and tailors others to individual circumstances

The Value of Minimal Access Surgery in the Staging of Patients with
Potentially Resectable Peripancreatic Malignancies
• 115 patients- radiologically resectable
• Extensive laparoscopy performed
– assessment of the peritoneal cavity, liver, lesser sac, porta hepatis, duodenum, transverse mesocolon, and celiac and portal vessels

Unresectability
• Metastases– hepatic, serosal, peritoneal
• Extrapancreatic extension– mesocolic involvement
• Nodal involvement– celiac or portal
• Vascular invasion– celiac axis or hepatic artery– portal vein, SMV, SMA

malignancy

Experience with staging laparoscopy in pancreatic malignancy
Gastrointest Endo 1999; 49(4):498-503
• 109 patients
• CT scan revealed metastases in 10 patients
• Laparoscopy diagnosed metastases in 29 more patients
• At laparotomy, 6 more patients were identified as having metastatic disease
![Page 15: Laparoscopic Pancreatic Surgery](https://reader033.vdocuments.mx/reader033/viewer/2022061611/5563c915d8b42abe468b4e17/html5/thumbnails/15.jpg)
Results
• Negative predictive value was 94%
• Positive predictive value was 88%
![Page 16: Laparoscopic Pancreatic Surgery](https://reader033.vdocuments.mx/reader033/viewer/2022061611/5563c915d8b42abe468b4e17/html5/thumbnails/16.jpg)
Conclusion
• In patients with a negative CT scan for metastasis, laparoscopic identification of metastasis avoided unnecessary laparotomy in 29 of 99 (29%) patients with pancreatic cancer. Staging laparoscopy is indicated in all cases of pancreatic malignancy before laparotomy.

Conclusion
Laparoscopic palliation can reduce the three major drawbacks of open bypass surgery-i.e., high morbidity, high mortality, and
long hospital stay.

SUMMARY
• Laparoscopy and laparoscopic ultrasound are sensitive and specific tools for determining resectability in patients with pancreatic cancer
• Laparoscopic techniques can be used for the treatment of benign and malignant pancreatic diseases and pancreatic trauma
