- Peritoneal carcinomatosis (PC) is defined as a metastatic involvement of the peritoneum by several other primary sites and it is characterized by a marked worsening of prognosis, with limited treatment opportunities. Subsequently, PC should be ruled out before any invasive treatment is administered. A new through-the-needle micro-biopsy forceps (MF) was recently introduced that permits micro-histology cores. In this case series, we evaluated the feasibility of MF in the assessment of PC to complete patient diagnostic work-ups. Five consecutive patients referred for endoscopic ultrasound staging were sampled using MF. Sampling was feasible in all patients with a technical success of 100%. No adverse events were reported in any cases. This technique was feasible and safe with a technical success rate of 100%. It permitted sampling of peritoneal irregularity, obtained high-quality tissue fragments in all cases, and enabled an additional assessment, i.e., immunohistochemical staining.

- Background
/Aims: Small polyps are the most frequently detected lesions during colonoscopy, with an incomplete resection rate of 6.8% to 15.9%. This study aimed to improve small polyp cold snare resection radicality using submucosal contrast dye pre-lifting (PL+CSP).
Methods
This single-center, prospective, randomized controlled trial compared the standard cold snare polypectomy technique (PL-CSP) with PL+CSP to evaluate endoscopic and histological complete resection rates, adverse events, procedural times, and polyp retrieval failure rates.
Results
In 143 patients consecutively enrolled, 186 small polyps were detected and randomly assigned following a 1:1 ratio to the PL-CSP (n=97, 51.6%) and PL+CSP (n=90, 48.4%) techniques. Endoscopic (p=0.97) and histologic complete resection rates (p=0.23) did not differ significantly even in univariate analysis. The intraprocedural bleeding rate was significantly higher in the PL+CSP (35.8% vs. 8.3%, p<0.001) group as confirmed by the univariate analysis (p<0.001). The polyps retrieval failure rates were similar (p=0.83). Procedural time was significantly longer for PL+CSP (median time, 75 vs. 45 seconds; p<0.001), without impacting colonoscopy withdrawal time (p=0.215).
Conclusions
PL+CSP of small polyps did not improve endoscopic and histological complete resection rates and polyp sample retrieval. PL+CSP had higher rates of intraprocedural bleeding and was “time-consuming”.
