disadvantages of midline incision

The abdominal part of the incision may consist of a midline or upper paramedian incision, which allows exploration of the abdomen. The potential advantages of the paramedian incision have also been investigated in prospective randomized trials, which have failed to demonstrate an advantage with regard to wound failure rates.4 A lateral paramedian incision refers to a vertical incision created several centimeters lateral to the location of the traditional paramedian incision.5 One randomized prospective study suggested a statistically significant decrease in the incidence of incisional hernia following closure of lateral paramedian incisions (0%) compared to medial paramedian incisions (14.9%) and midline incisions (6.9%).6. For most of the length of the paired recti, the anterior sheath is formed by the external oblique and anterior leaf of the internal oblique aponeuroses. Disadvantages include patients experiencing more pain than they would from a transverse incision, particularly during deep breathing postoperatively, and the incision is perpendicular to the Langers skin tension lines resulting in poorer cosmesis. Disadvantages include disruption of the innervation to the rectus lying medially. G. Closure midline and inferior rectus. They evaluate the degree of the tear and check for complications. These could be symptoms of an infection. The longitudinal incisions that will be reviewed here are the midline (median) and paramedian. A right subcostal incision is used commonly for operations in which exposure of the gallbladder and biliary tree is necessary. Surface markings.

This article will review the techniques for, as well as the rationale and disadvantages of, common incisionsboth longitudinal and transverseto help the gynecologic surgeon minimize morbidity and maximize outcomes. Ellis H, Coleridge-Smith PD, Joyce AD. Indeed, the adequacy of an incision is determined above all else by the safety with which an operation can be undertaken. Other recovery and complication rates are similar although the transverse incision may look better. For years, an episiotomy was thought to help prevent larger vaginal tears during childbirth. Philadelphia, PA: Lippincott Williams & Wilkins; 2001. Picture The closure is performed by reapproximating the . Disadvantages include the risk of injury to the ilioinguinal and iliohypogastric nerves. Last reviewed by a Cleveland Clinic medical professional on 05/03/2022. The stay sutures are then wrapped around the struts on the cannula to secure it in position. The avascular linea alba affords the vertical midline its superior flexibility. The midline incision allows rapid access to and adequate exposure of almost every region of the abdominal cavity and retroperitoneum. Your baby is in distress and needs to be delivered quickly. The posterior sheath is formed by the posterior leaf of the internal and the transversus abdominis aponeuroses and bears the superior and inferior epigastric arteries and their anastomotic network. This approach is commonly used for procedures requiring emergency laparotomy, such as in faecal peritonitis secondary to malignant intestinal perforation or in cases of ischaemic bowel. Purpose: Both midline and transverse abdominal incisions are used for exposing the infrarenal aorta. Your obstetrician needs to use forceps or a. other information we have about you.

If the operation requires extension of the wound laterally, this can be accomplished through division of the oblique muscles. 1980;7:188.-, 11. https://www.uptodate.com/contents/search.

Optimal exposure requires appropriate placement of retractors; use of a retractor system that can be contoured to the incision (eg, the Thompson retractor system, Thompson Surgical Instruments [Traverse City, MI], or other table-based self-retaining systems) is helpful in this regard (Fig. Both of these conditions may result in lengths of bowel becoming trapped within the hernial sac (incarcerated), and the hernia may be sufficiently large or the defect through which it protrudes may be sufficiently tight to occlude intraluminal passage of bowel content (obstruction), venous outflow and later arterial supply (strangulation). Surface markings of the right iliac fossa appendectomy incisions. The incision extends from the lateral margin of the rectus sheath at the level of the umbilicus toward the twelfth rib for approximately 12 to 14 cm (Fig. It is generally thought to be faster and easier to perform in the case of an emergency classical cesarean section.

Generic early complications declare themselves in the hours and days following the operation and may include atelectasis, postoperative pneumonia, urinary tract infection, oliguria, bedsores and deep vein thromboses. Your provider uses absorbable stitches to repair the tissues and muscles affected. It utilises the relatively avascular nature of the linea alba to access the abdominal contents without cutting or splitting muscle fibres in the process, with the exception of the small pyramidalis muscle at the pubic crest. Accessed Sept. 20, 2018. This type of tearing extends through the anal sphincter and into the mucous membrane that lines the rectum. Smelly discharge or pus is coming from the incision.

Transverse and oblique incisions generally follow Langers lines of tension and allow a more cosmetic closure than do vertical incisions. Left lumbar approach to the retroperitoneum. The disadvantages of the midline begin as the surgery ends with longer time for wound closure, higher . All rights reserved.

If the peritoneum is inadvertently entered, it is closed immediately. Br J Urol. The incision can also be extended superiorly as far as the costal margin if necessary. 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.

The suspected position of the appendix and the thickness of the abdominal wall influence the placement of the incision as well as its length. Further advantages include the ease with which the incision may be extended either cephalad or caudally in order to improve access. Use the arc, rather than direct contact, to prevent excessive devitalization of tissue. The vertical muscle-splitting incision is made in much the same way as the traditional paramedian incision except that the rectus muscle is split, rather than retracted laterally. The skin is then incised with a scalpel.

All randomised controlled trials comparing these incisions were identified. Disadvantages of a vertical incision include: Mediocre cosmetic results Higher infection rates, operative time, and hemorrhage with a paramedian incision Wound dehiscence (separation of the edges of wounds) and hernia may be common Oblique incisions are of two types: Once free, the rectus muscle is retracted laterally. Alternatively, when superior exposure of upper abdominal organs (eg, the esophagogastric junction) is required, thoracoabdominal incisions may be used. However, a transverse incision may be superior to a midline incision in terms of recovery and complications. Close proximity of a new incision to an old one should be avoided in order to minimize the risk of ischemic necrosis of intervening skin and fascial bridges. Potential disadvantages include the requirement for specialized equipment and training as well as the lengthy surgical times. Franchi M, Ghezzi F, Bendetti-Panici PL, et al. It'll take time for the baby to stretch the vaginal tissues to allow delivery. Chapters: Butler Tobah YS (expert opinion). Surg Clin North Am. 74).

Notwithstanding this, the incision should be executed in a fashion that anticipates a secure wound closure and interferes as little as possible with the function and cosmesis of the abdominal wall.
