Tuberculous peritonitis diagnosed using laparoscopy with assistance of a central venous catheter

Laparoscopy with peritoneal biopsy is a tool for rapid and accurate diagnosis of tuberculous peritonitis (TBP). However, laparoscopic procedures are not risk-free; complications include injuries to the gastrointestinal tract and major blood vessels. The purpose of the present study was to introduce a novel method for safe and straightforward laparoscopic diagnosis of TBP. A case series of 12 patients with TBP diagnosed between October 2012 and November 2013 at our hospital is presented. The patients underwent a novel method of laparoscopy involving the use of a central venous catheter (CVC). The diagnosis was confirmed by biopsy and histology. The efficacy of the method for TBP diagnosis was evaluated by the time taken for the procedure and the rate of successful completion. The safety of the method was evaluated by recording all intra- and post-operative adverse events encountered. The mean age of the patients was 41 years and 33% were male. The mean operation time was 50.6 min and the median duration of hospital stay was 7 days. In all cases, diagnostic laparoscopy was successfully performed. Targeted biopsies were taken from all of the patients and revealed caseous granulomatous inflammation. All patients tolerated the procedure without significant bleeding or digestive tract perforation. In conclusion, the present case series demonstrated a novel method of diagnostic laparoscopy with CVC that is a feasible and straightforward procedure for TBP diagnosis.
