This incision is oriented obliquely. 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. (Reproduced with permission from Baker RJ, Fischer JE: Mastery of Surgery, 4th ed. Heavy stay sutures are then placed in each fascial edge and are lifted up while a blunt-tipped (Hasson) obturator and cannula are inserted through the opening in the abdominal wall. Despite these concerns, little evidence supports a substantial benefit of transverse incisions, and proponents of vertical incisions argue that larger transverse incisions obligate division of muscle fibers with greater functional consequences and leave fewer options for remediation when hernias do develop. Theoretical decreased risk of herniation; Improved lateral exposure; Disadvantages. 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. You may opt-out of email communications at any time by clicking on Aasheim V, et al.

The posterior sheath (above the arcuate line) and peritoneum are then incised to gain entry into the abdomen. Pain during sex after an episiotomy is common for several months. Use an ice pack or perineal cold pack (an ice pack and absorbent pad in one) to reduce swelling and ease soreness. 10-9). Today, however, research suggests that routine episiotomies don't prevent these problems after all. Facebook: http://www.facebook.com/geekymedics Point defects in the aponeurotic intersections of the linea alba may facilitate the development of epigastric hernias, which often simply contain preperitoneal fat but are often disproportionately painful for their size owing to their high tendency to strangulate. 8. https://www.uptodate.com/contents/search. C. Dividing in the midline and entering the peritoneal cavity. health information, we will treat all of that information as protected health A bilateral subcostal incision affords excellent exposure of the upper abdomen. If you have an episiotomy, it's because it was the safest for you or your baby. The midline incision allows rapid access to and adequate exposure of almost every region of the abdominal cavity and retroperitoneum. 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. These factors are the key determinants of whether the incision will be longitudinal (midline or paramedian) or transverse (Pfannenstiels, Cherneys, or Maylards). 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.

Mayo Clinic offers appointments in Arizona, Florida and Minnesota and at Mayo Clinic Health System locations. The information provided is for educational purposes only. While I recently have switched to the latter, here is a look at what the data say: Johnson and Serpell demonstrated that electrosurgery is associated with faster hemostasis, with no difference in the incidence of wound infection.1 Similarly, a recent randomized trial by Kearns et al found electro-surgery causes less blood loss and does not increase the risk of wound infections or fascial dehiscence.2 In contrast, a large prospective study by Cruse et al suggested that the use of diathermy is associated with twice the wound infection rate.3, This controversy also involves patients with gynecologic malignancies. You'll get anesthesia so you don't feel pain. There is no posterior sheath above the level of the costal margin, as the recti remain covered anteriorly by the external oblique aponeurosis and insert directly onto the underlying costal cartilages. During creation of a paramedian incision in the lower abdomen, the inferior epigastric vessels may be encountered and must be ligated prior to division (Fig. 1980;7:188.-, 11. The peritoneum has been bluntly dissected from the retroperitoneal structures with the preperitoneal fat and soft tissue. The McBurney incision has largely been supplanted by the Rockey-Davis incision, which is oriented transversely as opposed to obliquely, allowing for better cosmesis (Fig. 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. The rectus sheath may be considered as having three distinct sections: 1. If you are a Mayo Clinic patient, this could This can be achieved using an open or closed technique. The paired rectus abdominis muscles originate from the anterior bony pubic bones toward the midline and run cephalad to insert onto the xiphisternum and costal cartilages of ribs 5-7. If the peritoneum is unintentionally entered, it is closed immediately with continuous absorbable suture. The sheath is bounded laterally by the linea semilunaris, which is the longitudinal margin at which the internal oblique aponeuroses bifurcate to form anterior and posterior leaves. Positioning is aided by the use of a bean bag. B. Peritoneum is retracted medially by blunt dissection, which exposes the psoas muscle and gonadal artery and vein, shown anterior to the ureter.

(Reproduced with permission from Baker RJ, Fischer JE: Mastery of Surgery, 4th ed. Transverse and oblique incisions generally follow Langers lines of tension and allow a more cosmetic closure than do vertical incisions. Indeed, the adequacy of an incision is determined above all else by the safety with which an operation can be undertaken. 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. include protected health information. B-Lynch suture technique, HMO comments questioned, Injecting 30 cc of 2% lidocaine challenged, Physician denies bleeding caused coagulation problem. A. Kolb et al found that electrosurgery was an independent risk factor for wound complications following surgery for ovarian cancer.4 However, Franchi and colleagues reported no difference in the rate of wound complications between scalpel and diathermy in patients who underwent mid-line abdominal incisions for the treatment of uterine cancer.5. generic complications of surgery vs those specific to the operation, and presenting as immediate, early or late complications.

Without an excessive pressure on the intestines (w hich would The interrupted sutures are tied prior to skin closure and reinforce the running closure. Like the paramedian approach, the pararectal incision has now largely been abandoned. B. 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. The stay sutures are then wrapped around the struts on the cannula to secure it in position. 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: With few exceptions, vertical midline incision through the linea alba is the standard and preferred technique. The erector spinae muscle is exposed and retracted medially to uncover the twelfth rib and the middle layer of the lumbodorsal fascia.
