Vomiting of undigested food can occur and can become bilious i.e., green or yellow when the blockage becomes severe.

  • udiesAnatomy of the swine mesenteric artery arcade.The swine mesenteric vasculature is substantially different from that of other species commonly used in studies of the intestinal circulation and so merits a brief description. Intestinal perfusion is derived from a single mesenteric artery, which gives rise to a series of short first-order branches whose initial diameters become progressively smaller in a proximal-to-distal gradient. All first-order branches enter an arterial plexus, which in 1- to 35-day-old swine is approximately 1–2 cm lateral to the mesenteric arterial trunk and is a site of extensive arterial collateralization (Fig.1). This plexus is generally not appreciated on initial visual inspection of the swine mesentery because it lies buried
  • ath a compact network of lymph nodes. Arising from this plexus are a dense series of terminal arteries that run, unbranched, directly to their insertion sites within the gut wall. In contrast to the anatomic pattern characteristic of the dog, cat, and rat intestine, collateralization among arteries at their insertion site into the gut wall does not occur in swine. Instead, arterial collateralization is limited to the arterial plexus, from which arise the terminal arteries.

  • ApplicationsThe results of the present study suggest that 2 wk of anisodamine administration can safely accelerate spontaneous passage of single and symptomatic CBD stones ≤ 10 mm in diameter in symptomatic patients. These findings indicated that conservative treatment could be the first-line management for these patients, especially for those with stones < 5 mm.Peer reviewThe authors undertook a randomized controlled trial investigating if anisodamine accelerated spontaneous passage of single symptomatic CBD stones ≤ 10 mm in diameter. The study was well conducted and the results are interesting that 47.0% of CBD stones ≤ 10 mm in diameter passed spontaneously with the aid of a 2-wk course of anisodamine.Go to:FootnotesP- Reviewers Endo I, Ladas SD S- Editor Gou SX L- Editor Ma JY E- Editor Ma SGo to:References1.

    "st clinicians specializing in hepatobiliary medicine are familiar with spontaneous passage of CBD stones, and such passage is recognized in the literature[1,13-16]. Collins et al[1] reported that 12/34 of silent CBD stones confirmed by intraoperative cholangiography in selective LC passed spontaneously 6 wk after the procedure. Frossard et al[13] evaluated the prevalence and time-course of CBD stone passage in symptomatic patients by analyzing discrepancies between endoscopic ultrasonography and ERCP as a function of the time elapsed between these two procedures. They found that the rate of spontaneous passage of CBD stones was 21% (12/57), and that the rates of spontaneous passage in different periods (from 6 h to 3 d and from 3 to 27 d) were 21% (8/37) and 20% (4/20), respectively. They also concluded that stone diameter was the only factor that predicted passage, and that the rate of spontaneous passage of stones with a diameter of > 8 mm was only 4.3% (2/47). Tranter et al[14] conducted a study in 1000 patients to determine the rate of spontaneous passage of CBD stones and related it to the various presentations of CBD stones. They found that 390/532 CBD stones passed spontaneously, but they did not specify the observation period. Lefemine et al[15] retrospectively investigated 108 patients presenting with jaundice due to CBD stones, and found that spontaneous passage of CBD stones occurred in 60 (55.6%) of 108 patients within approximately 4 wk. The inclusion criteria of the latter two studies[14,15] were not strict: patients with a history of jaundice, pancreatitis, abnormal results of liver function tests, or a dilated CBD were assumed to have a history of CBD stones. Therefore, the reported rates of spontaneous passage were probably overestimated. Reported rates of spontaneous passage of CBD stones vary mainly because of different inclusion criteria and research methods used[1,13-15]. However, studies have demonstrated that a significant portion of CBD sto

Inferior mesenteric artery aneurysms are the rarest of visceral aneurysms. The authors report a case of an aneurysm of the inferior mesenteric artery in a 52-year-old man with obstructive disease of superior mesenteric artery and celiac axis. The diagnosis was made by angiography. The aneurysm was resected with superior and inferior mesenteric arteries revascularization. Surgical approach is needed in these aneurysms and when they are associated with obstructive disease of other intestinal artery, revascularization is mandatory.
