Paracentesis (from Greek κεντάω, "to pierce") is a form of body fluid sampling procedure, generally referring to peritoneocentesis (also called laparocentesis or abdominal paracentesis) in which the peritoneal cavity is punctured by a needle to sample peritoneal fluid. [1] [2]
This procedure is performed when intra-abdominal bleeding (hemoperitoneum), usually secondary to trauma, is suspected. [2]In a hemodynamically unstable patient with high-risk mechanism of injury, peritoneal lavage is a means of rapidly diagnosing intra-abdominal injury requiring laparotomy, but has largely been replaced in trauma care by the use of a focused assessment with sonography for ...
Ascites (/ ə ˈ s aɪ t i z /; [5] Greek: ἀσκός, romanized: askos, meaning "bag" or "sac" [6]) is the abnormal build-up of fluid in the abdomen. [1] Technically, it is more than 25 ml of fluid in the peritoneal cavity, although volumes greater than one liter may occur. [4]
Surgery, consisting of excision of part of the lower stomach, also called antrectomy, is another option. [6] [16] Antrectomy is "the resection, or surgical removal, of a part of the stomach known as the antrum". [2] Laparoscopic surgery is possible in some cases, and as of 2003, was a "novel approach to treating watermelon stomach". [26]
The diagnosis of SBP requires paracentesis, a sampling of the peritoneal fluid taken from the peritoneal cavity. [6] If the fluid contains large numbers of white blood cells known as neutrophils (>250 cells/μL), infection is confirmed and antibiotics will be given, without waiting for culture results . [ 7 ]

Barium X-ray examinations are useful tools for the study of appearance and function of the parts of the gastrointestinal tract. They are used to diagnose and monitor esophageal reflux, dysphagia, hiatus hernia, strictures, diverticula, pyloric stenosis, gastritis, enteritis, volvulus, varices, ulcers, tumors, and gastrointestinal dysmotility, as well as to detect foreign bodies.
Rarely, there are peristaltic waves that may be felt or seen (video on NEJM) due to the stomach trying to force its contents past the narrowed pyloric outlet. [ citation needed ] Most cases of pyloric stenosis are diagnosed/confirmed with ultrasound , if available, showing the thickened pylorus and non-passage of gastric contents into the ...
