title: Role of diagnostic laparoscopy in assessing operability in borderline resectable gastrointestinal cancers.
abstract: BACKGROUND
  Diagnostic laparoscopy helps in diagnosing and staging Gastrointestinal (GI) cancers. Routine laparoscopy before laparotomy, especially in cancers that have equivocal operability, helps to avoid unnecessary laparotomies. Present study evaluates utility of laparoscopy in diagnosing and staging GI cancers.
  
  
  METHODS
  Diagnostic laparoscopy was done in 41 patients with gastrointestinal (GI) cancers who were thought to have equivocal operability. Patients with suspected or known non-metastatic GI cancers, in whom resectability was found doubtful by clinical assessment and pre-operative imaging, were included. Patients with non-GI cancers (lymphoma, gynaecologic cancers, genitourinary cancers, retroperitoneal sarcoma, sarcoma and abdominal metastasis of non-GI cancers) and metastatic cancers which were beyond the scope of curative surgery were excluded from the study.
  
  
  RESULTS
  After diagnostic laparoscopy (DL) five patients had benign diagnosis. Out of 36 patients with malignant diagnosis, after DL, 22 patients (61.1%) were inoperable, 11 patients (30.6%) were operable, and three (8.3%) patients were of equivocal operability. Sensitivity, specificity, positive predictive value, and negative predictive value of laparoscopy in detecting operability were 100%, 91.7%, 81.8%, and 100%, respectively.
  
  
  CONCLUSIONS
  Laparoscopy helped in a significant number of patients with advanced GI cancers to avoid laparotomy. The morbidity of DL was acceptable.
