Join the Geeky Medics community: Instagram: https://instagram.com/geekymedics Following incision of the rectus sheath along the plane of the skin incision, the rectus muscle is divided using electrocautery or ligatures to control branches of the superior epigastric artery. Episiotomy is a procedure in which your obstetrician makes a small cut between the bottom of your vaginal opening and anus (an area called the perineum) during childbirth. Appropriate alignment of the closure is facilitated by initial placement of interrupted sutures at the edge of the rectus muscle, junction of the transverse and vertical portions of the incision, and superior aspect of the vertical incision. Also call your provider if you develop a fever or if the wound produces pus. This wound can be opened and closed quickly and is of particular value in reopening a previous paramedian incision where dissection of the rectus muscle away from the rectus sheath can be difficult. Classically, it was thought that longitudinal incisions were at greater risk of dehiscence than transverse incisions.6 However, it is difficult to make legitimate comparisons since longitudinal incisions are more likely to be performed in cases of hemorrhage, trauma, sepsis, multiorgan disease, previous surgery, previous radiation therapy, and malignancyall of which increase the likelihood of postoperative complications. If you haven't had anesthesia or if the anesthesia has worn off, you'll likely receive an injection of a local anesthetic to numb the tissue. Disadvantages include the risk of injury to the ilioinguinal and iliohypogastric nerves. They provide entry to the liver, lungs and spleen, as well as to the stomach and esophagus. Within the abdomen lie the majority of the digestive tract and associated structures such as the liver, biliary tree, pancreas, kidneys and ureters, and the occasional pair of surgeons hands. Such hand-assisted laparoscopic approaches are frequently associated with shorter operative times than are purely laparoscopic approaches and may have particular advantages for operations in which a larger incision is necessary to remove the surgical specimen (eg, laparoscopic colectomy) and more complex procedures.15 The initial step of any laparoscopic procedure is the establishment of pneumoperitoneum. E. Lateral retractors are placed for exposure.

Smelly discharge or pus is coming from the incision. In some cases, you've already had an epidural and can't feel anything from your waist down. The incision should be considered as a second surgical procedure, which temporarily interferes with normal abdominal wall function. In some cases, there will be anastomotic branches of the superior and inferior epigastric vessels crossing from either side, but the incision generally avoids major neurovascular bundles. 5. Like midline incisions, paramedian incisions obviate division of nerves and the rectus muscle and may be made in the upper or lower abdomen. Use of this Web site is subject to the medical disclaimer.

In certain situations, an episiotomy helps reduce the risk of a bad natural tear. The use of chlorhexidine gluconate has been associated with greater reductions in skin bacterial counts and lower rates of surgical site infection when compared to povidone-iodine in a number of studies8-11 and is emerging as the preferred skin antiseptic.

The lateral abdominal walls are formed by a triad of muscles: the external oblique (E.O), with its fibres running inferomedially like the fingers of the hands placed into the front pockets of ones jeans; the internal oblique (I.O) with its fibres running orthogonally to its external relation, and transversus abdominis (T.A) with its horizontal fibres. The midline incision provides excellent exposure to all areas of the abdomen and retroperitoneum, which can be accessed with minimal risk of significant vascular or nerve injury. Br J Surg. Like the paramedian approach, the pararectal incision has now largely been abandoned. 1980;7:188.-, 11. A. In contrast, vertical incisions disrupt fascial fibers and must be reapproximated with sutures placed between fibers.1 In the latter case, the absence of an anatomic barrier may predispose to tearing of tissues, resulting in dehiscence or hernia formation. In practice, when these incisions are reopened, the medial edge of the rectus muscle is frequently adherent to the anterior or posterior sheath incision and does not effectively buttress the wound. The erector spinae muscle is exposed and retracted medially to uncover the twelfth rib and the middle layer of the lumbodorsal fascia.

Generally, an episiotomy follows this process: Like perineal tears, healthcare providers describe the levels (or degrees) of episiotomy in relation to how severe the tear is. A mediolateral incision offers the best protection from an extended tear affecting the anal area, but it is often more painful and is more difficult to repair. Left lumbar approach to the retroperitoneum. Complications during surgery can occur because of inadequate exposure, which is often due to the unwillingness of the surgeon to extend the incision. Indeed, when optimal exposure of the entire abdominal cavity is necessary (eg, exploration for abdominal trauma), the vertical midline incision is preferred and can be extended superiorly to the xiphoid process and inferiorly to the symphysis pubis.

Running closure of the fascial layers can then be undertaken. Perineal techniques during the second stage of labour for reducing perineal trauma. Pain during sex after an episiotomy is common for several months. After skin and subcutaneous tissues are incised, the external oblique aponeurosis is exposed and divided parallel to the direction of its fibers to reveal the underlying internal oblique muscle.
