More wound infections were seen with transverse incisions.3, Controversy also persists regarding the relative advantages of midline versus paramedian incisions. See our Other Publications. Learn about the risks, benefits and recovery. Defects in the integrity of the internal oblique may give rise to the formation of Spigellian hernias, allowing protrusion of the peritoneal sac into the rectus sheath. generic complications of surgery vs those specific to the operation, and presenting as immediate, early or late complications. Surface markings. Transverse incisions create less tension on the opposing skin edges because the incision follows Langers lines. E. Lateral retractors are placed for exposure. information submitted for this request. A. Normal labor and delivery. Insufflation tubing is then attached to the cannula and the obturator is withdrawn. The thoracoabdominal incision provides enhanced exposure of upper abdominal organs. Part I: Influence on healing. Approach to episiotomy.

Use the arc, rather than direct contact, to prevent excessive devitalization of tissue. B. Greenall MJ, et al. If the pleura is opened, the wound closure is performed over a pleural suction catheter, which is removed with simultaneous positive airway pressure by the anesthetist as the skin is being closed. 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 Langer's skin tension lines resulting in poorer cosmesis. Today, however, research suggests that routine episiotomies don't prevent these problems after all. However, this incision is often more painful and more difficult to repair. Structures within the transpyloric plane: Complications are best considered in terms of specificity and chronicity; i.e. The retroperitoneum is entered and the peritoneum and retroperitoneal fat are swept anteriorly. The lower abdominal midline incision should be employed if optimal exposure is desired. 10-12). 10-9). Kolb BA, Buller RE, Connoer JP, et al. surgical technique, site and orientation of incision, intra-operative contamination, lengthy procedure). 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. 1977;112:1188.-, 9. A multicenter collaborative study on the use of cold scalpel and electrocautery for midline abdominal incision. 4. 1980;7:188.-, 11. Most hospitals have perineal cold packs, but you can also purchase them yourself. A midline incision will thus encounter the following layers of tissue: The scar of a paramedian incision may be seen running parallel to the midline in a limited number of patients but has fallen from common practice in favour of the midline incision due to its complexity and poor cosmesis. The high combined incidence of surgical site infection, wound dehiscence, and hernia formation suggests a dominant contribution of wound complications to surgical morbidity. One randomized controlled trial compared vertical and transverse incisions with regard to the frequency of evisceration; no significant difference in outcome was observed with either technique.2 In a more recent prospective randomized trial, no significant differences in 30-day mortality, pulmonary complications, median length of hospital stay, median time to tolerate solid food, and incisional hernia formation at 1 year were observed. 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. .With the animal on its back, an incision is made in the center of the abdomen.

A midline (median) incision (shown at left) is done vertically. Your obstetrician needs to use forceps or a. While most physicians concur that the essential elements of a well-planned incision include adequate access to anticipated pathology, extensibility, and security of closure, many may not consider preservation of abdominal wall function as a key factor in their decision-making. The arc may be extended cephalad and laterally in order to facilitate access to the ascending colon, which is known as the Rutherford-Morison incision. The incision should not be placed too far superiorly because sufficient fascia must be preserved to allow a secure abdominal closure. If the peritoneum is inadvertently entered, it is closed immediately.

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. . When broad exposure is required, as in an exploration for trauma, the midline incision can be extended to the xiphoid process superiorly and to the pubic symphysis inferiorly. 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.

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). 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.
