The most common neoplasms that affect the peritoneum are the metastatic carcinoma (of colon, ovary and stomach, and less frequently, of pancreas, bile duct, and uterus), and the lymphoma. Other even more rare etiologies are the bladder carcinoma, the gastrointestinal leiomyosarcomas, and metastatic melanomas. The primary mesenteric carcinoid tumor, the epyplon and peritoneum neoplams are less common and, in general, they have mesenchymal origin. Among the benign process we find granulomatous conditions, hematomas, infections or inflammatory processes–all of them much less commom.<a class="elsevierStyleCrossRefs" href="#bib0070"><span class="elsevierStyleSup">1–3</span></a></p><p id="par0010" class="elsevierStylePara elsevierViewall">The metastatic damage may occur in the form of a mass or diffuse infiltration of fat due to contiguity, or lymphatic or hematogenous dissemination. Also, metastatic nodules can be seen both on the peritoneal surface and the mesentery, with variable sizes ranging from a few millimeters to several centimeters conguring genuine masses. In other cases, only the diffuse thickening of the peritoneum is evident. Both the primary peritoneal tumors and the benign processes described can show overlapping findings in the different imaging modalities.<a class="elsevierStyleCrossRefs" href="#bib0070"><span class="elsevierStyleSup">1–4</span></a> For all this, it is essential to obtain a specimen to conduct the histological study and know what the origin really is. The biopsy will be particularly important in patients with a history of a known tumor because we will be able to confirm the origin of tumor and know whether it is metastatic, a tumor of a different origin, or a benign lesion, so we can prescribe the most appropriate oncological treatment in each case.<a class="elsevierStyleCrossRef" href="#bib0090"><span class="elsevierStyleSup">5</span></a> The laparoscopy procedure allows us to detect peritoneal lesions and obtain tissues, even from different areas of the lesion, in order to be able to make a diagnosis with high diagnostic reliability.

Both techniques allow us to detect peritoneal lesions, and even obtain biopsies of different areas of the lesion, but they require anesthesia and have a higher rate of complications.<a class="elsevierStyleCrossRefs" href="#bib0095"><span class="elsevierStyleSup">6,7</span></a></p><p id="par0125" class="elsevierStylePara elsevierViewall">Ever since Pombo et al.<a class="elsevierStyleCrossRef" href="#bib0125"><span class="elsevierStyleSup">12</span></a> published their series on CT-guided percutaneous biopsies back in 1997, other series of imaging-guided (through CT scans or ultrasounds) percutaneous biopsies of omental lesions have been published.

However, with diagnoses of benignity, the possibility of one false negative (50% in our series) cannot be excluded, being this the main limitation of percutaneous biopsies. In our study, the results of malignity from the percutaneous biopsy (both ultrasound and CT-guided) are very reliable comparted to the results of benignity. Since the chances of malignant etiology are high, particulary in patients with a prior history of neoplasms, one result of benignity in the percutaneous biopsy would make us undecided about its true value, which is why it would be advisable to re-evaluate the case, re-obtain the percutaneous or surgical biopsy, or keep a narrow follow-up.</p><p id="par0140" class="elsevierStylePara elsevierViewall">Therefore, the imaging-guided percutaneous biopsy is one procedure with a high rate of diagnostic reliability, and a low rate of complications that, even in our hospital, has taken over the laparoscopy procedure, and the exploratory laparotomy.<a class="elsevierStyleCrossRefs" href="#bib0095"><span class="elsevierStyleSup">6,7</span></a></p><p id="par0145" class="elsevierStylePara elsevierViewall">Due to the risk of puncturing the small bowel and the colon, and how difficult it is to see adjacent lesions, the CT scan has been the most widely accepted imaging modality to perform biopsies of the peritoneum and the omentum. However, compared to the ultrasound, it is more expensive, less fast, and uses ionizing radiation.<a class="elsevierStyleCrossRef" href="#bib0115"><span class="elsevierStyleSup">10</span></a> The main benefit of the ultrasound is that it allows us to see, real time, both the lesion and the trajectory of the needle while conducting the biopsy and, also, with the Doppler study, allows us to identify the vascular structures we should be avoiding during the puncture.

In all the biopsies, the samples obtained were diagnostic regardless of the imaging modality used. Thus, based on everything that has been published so far, and based on our own experience, and taking into consideration the benefits of the ultrasound, we reserve the CT scan for the guidance of deeply located lesions (root of the mesentery), with interposed loops, or lesions of pelvic location that will require posterior access (whether translumbar or transgluteal access).</p><p id="par0155" class="elsevierStylePara elsevierViewall">The peritoneal/omental damage has several patterns: masses or nodules, diffuse infiltration, or “omental cake”.

The availability, in all cases, of the abdominal CT scan facilitates the location, identification, and individualization of the lesion (particularly, in those of superficial location), and its association with adjacent structures. Back in 1998, Gottlieb et al.<a class="elsevierStyleCrossRef" href="#bib0115"><span class="elsevierStyleSup">10</span></a> published their series of 52 patients who underwent ultrasound-guided percutaneous biopsy procedures, in all cases after prior CT assessment, with a similar diagnostic reliability than the one reported by the series published of CT-guided biopsies; only in two (2) patients, the sample obtained was insufficient to establish the diagnosis.</p><p id="par0165" class="elsevierStylePara elsevierViewall">The first series of percutaneous biopsies of diffuse infiltrations of the peritoneum with no mass or nodularity was published back in 2011. Lee et al.<a class="elsevierStyleCrossRef" href="#bib0120"><span class="elsevierStyleSup">11</span></a> conducted the ultrasound-guided percutaneous biopsy of 45 patients with 84% diagnostic reliability. In all the patients, the area of maximum diffuse infiltration of the peritoneum according to the CT scan was used as the target for the ultrasound-guided sampling. In the ultrasound it looked like an area of increased mobile echogenicity during the puncture, but through ultrasound guidance, they managed to place the needle in the area of interest, avoiding blood vessels and small-bowell loops. In our own experience, even the cases of diffuse infiltration (n<span class="elsevierStyleHsp" style=""></span>=<span class="elsevierStyleHsp" style=""></span>16) may be eligible for ultrasound-guided biopsy procedures.

The choice of the biopsy area, and the trajectory of the needle is essential. In order to obtain better material, it is important to make a right choice of the solid areas of the mass or nodule, or the areas whose structure is mostly altered in the diffuse infiltration. Similarly, choosing correctly the angle of the biopsy needle in relation to the biopsy area will, also, allow us to obtain good samples, particularly from the smallest lesions.</p><p id="par0175" class="elsevierStylePara elsevierViewall">The fine needle biopsy (usually 20-25 G) allows us to obtain tissues for cytological studies.

Back in 2003, Ho et al.<a class="elsevierStyleCrossRef" href="#bib0110"><span class="elsevierStyleSup">9</span></a> published, in their series of 25 patients, one case of mesenteric hematoma following the biopsy of one lymphatic nodule that resolved with conservative measures. They think it was due to blood vessel laceration during the biopsy, since the patient showed no alterations in coagulation, there were no more passess than the usual, or technical difficulties. They wish to emphasize the importance of the Doppler ultrasound assessment of blood vessels in order to avoid them during the puncture. Until that date, only one case of mesenteric hemorrhage due to one CT-guided percutaneous biopsy had been reported. Then back in 2013, Wang et al.<a class="elsevierStyleCrossRef" href="#bib0100"><span class="elsevierStyleSup">7</span></a> published their series of 153 ultrasound-guided biopsies, in which, in two cases, the postoperative ultrasound confirmed bleeding that resolved with transducer compression. In our series, we had one case (1.75%) of major complication due to bleeding from the anterior abdominal wall after puncturing the inferior epigastric artery. Given the associated hemodynamic instability, the patient required endovascular treatment through arterial embolization, but eventually died. It was one single 15<span class="elsevierStyleHsp" style=""></span>mm long-nodule of superficial location in the omentum that was CT-guided biopsized. The biopsy was conducted using the standard procedure, and no more passes than usual were made. Probably, in these cases of small, mobile nodules of superficial location, the ultrasound guidance of the procedure, with the advantages already mentioned here (real time assessment of the lesion and vascularization), is extremely useful and allows us to reduce the rate of complications due to arterial punctures.</p><p id="par0190" class="elsevierStylePara elsevierViewall">Among the limitations worth mentioning here is the single-center retrospective nature of the study, and with a sample where the prevalence of malignant etiology of the biopsy was very high (only one benign lesion was biopsized).</p><p id="par0195" class="elsevierStylePara elsevierViewall">In sum, we consider the percutaneous core needle biopsy a highly sensitive technique regardless of the imaging modality used to guide the puncture (CT scan or ultrasound), and the type of lesion biopsized (mass, nodule, or diffuse infiltration). The rate of true positives is extremely high, whereas the rate of false negatives is low, which makes a result of malignity very reliable compared to a result of benignity.
