In the male acne 14 dpo cheap bactroban 5gm with mastercard, the peritoneal cavity is completely closed skin care hospitals in bangalore purchase bactroban no prescription, but in the female it is perforated by the openings of the uterine tubes which constitute a pos- sible pathway of infection from the exterior skin care at 30 buy bactroban with a visa. To revise the complicated attachments of the peritoneum, it is best to start at one point and trace this membrane in an imaginary round-trip of the abdominal cavity, aided by Figs 47 and 48. At this level the membrane is smooth apart from the shallow ridges formed by the median umbilical fold (the obliterated fetal urachus passing from the bladder to the umbilicus), the medial umbilical folds (the obliterated umbilical arteries passing to the umbilicus from the internal iliac arteries) and the lateral umbilical folds (the peritoneum covering the inferior epigastric vessels). A cicatrix can usually be felt and seen at the posterior aspect of the umbilicus, and from this the falciform ligament sweeps upwards and slightly to the right of the midline to the liver. In the free border of this ligament lies the ligamentum teres (the obliterated fetal left umbilical vein) which passes into the groove between the quadrate lobe and left lobe of the liver. Elsewhere, the peritoneum sweeps over the inferior aspect of the diaphragm, to be reflected on to the liver (leaving a bare area demarcated by the upper and lower coronary ligaments of the liver) and on to the right margin of the abdominal oesophagus. After enclosing the liver (for further details, see page 95), the peritoneum descends from the porta hepatis as a double sheet, the lesser omentum, to the lesser curve of the stomach. Here it again splits to enclose this organ, reforms at its greater curve, then loops downwards, then up again to attach to the length of the transverse colon, forming the apron-like greater omentum. The transverse colon, in turn, is enclosed within this peritoneum which then passes upwards and backwards as the transverse mesocolon to the posterior abdominal wall, where it is attached along the anterior aspect of the pancreas. Peritoneal cavity 67 Falciform ligament Liver Stomach Portal triad (portal vein, hepatic artery Greater sac and common bile duct) Foramen of Winslow Spleen with its lienorenal and gastrosplenic ligaments Lesser sac (a) Stomach Liver Aorta Superior aspect of pancreas with splenic artery Spleen L. At the base of the transverse mesocolon, this double peritoneal sheet divides once again; the upper leaf passes upwards over the posterior abdominal wall to reflect on to the liver (at the bare area), the lower leaf passes over the lower part of the posterior abdominal wall to cover the pelvic viscera and to link up once again with the peritoneum of the anterior wall. This posterior layer is, however, interrupted by its being reflected along an oblique line running from the duodenojejunal flexure, above and to the left, to the ileocaecal junction, below and to the right, to form the mesentery of the small intestine. The mesentery of the small intestine, the lesser and greater omenta and mesocolon all carry the vascular supply and lymph drainage of their con- tained viscera. The right extremity of the sac opens into the main peritoneal cavity via the epiploic foramen or foramen of Winslow (Fig. Clinical features 1Occasionally a loop of intestine passes through the foramen of Winslow into the lesser sac and becomes strangulated by the edges of the foramen. Notice that none of these important boundaries can be incised to release the strangulation; the bowel must be decompressed by a needle to allow its reduction. If the cystic artery is torn during cholecystectomy, haemor- rhage can be controlled by this manoeuvre (named after James Pringle), which then enables the damaged vessel to be identified and secured. Intraperitoneal fossae A number of fossae occur within the peritoneal cavity into which loops of bowel may become caught and strangulated. Those of importance are: 1the lesser sac via the foramen of Winslow, described above; 2paraduodenal fossa—between the duodenojejunal flexure and the inferior mesenteric vessels; 3retrocaecal fossa—in which the appendix frequently lies; 4intersigmoid fossa—formed by the inverted V attachment of the mesosigmoid. One or more of these spaces may become filled with pus (a subphrenic abscess) walled off inferiorly by adhesions. The right and left subphrenic spaces lie between the diaphragm and the liver, separated from each other by the falciform ligament. The right is the pouch of Morison and is bounded by the posterior abdominal wall behind and by the liver above. It communicates anteriorly with the right sub- phrenic space around the anterior margin of the right lobe of the liver and below both open into the general peritoneal cavity from which infection may track, for example, from a perforated appendix or a perforated peptic ulcer. The left subhepatic space is the lesser sac which communicates with the right through the foramen of Winslow. It may fill with fluid as a result of a perforation in the posterior wall of the stomach or from an inflamed or injured pancreas to form a pseudocyst of the pancreas. Posterior subphrenic abscesses are drained by an incision below, or 70 The abdomen and pelvis through the bed of, the 12th rib. A finger is then passed upwards and for- wards between liver and diaphragm to open into the abscess cavity.
