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. Still, the procedure is sometimes needed. This can be achieved using an open or closed technique. To avoid injuries to the bladder, the peritoneum is entered in the upper portion of the incision. This incision can be extended into a T-incision with a vertical midline skin incision, and either a partial or a complete sternotomy can be . The primary alternative to these transverse incisions is the vertical midline incision, which is unparalleled for extensibility and access to all aspects of the abdomen (see Chap. These advantages and disadvantages are summarized in Table 84.1 (for low transverse incisions) and Table 84.2 (for high transverse incisions). Berkowitz LR, et al. The abdomen is tilted approximately 45 degrees from the horizontal plane, and the thorax is oriented in full lateral position (Fig. The perineal area will be sore and painful for a few weeks after an episiotomy. The skin incision may be shorter than depicted in thinner patients or if an abscess is to be drained. Specific early complications include reactionary haemorrhage where small vessels ooze and intra-operative haemostasis fails once the blood pressure normalises, intra-abdominal collection, postoperative ileus and wound infection. ), After entry into the peritoneal cavity through the abdominal portion of the incision, the incision is extended onto the chest wall and the latissimus dorsi and serratus anterior muscles, and then the external oblique muscle and aponeurosis are divided. 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. This content does not have an Arabic version. Outcomes included analgesic use, pulmonary function, complication rates and hospital stay. 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. Learn about the risks, benefits and recovery. C. Dividing in the midline and entering the peritoneal cavity. Fecal incontinence could result. 3. The anterior border of the rectus sheath is exposed and incised across the entire length of the wound. A curvilinear incision is made beginning on the tenth rib approximately 3 fingerbreadths lateral to the mid-line and carried inferiorly and laterally toward the iliac crest, ending approximately 4 fingerbreadths lateral to the midline (Fig. B. Access is most often obtained at a site just above or below the umbilicusthe thinnest portion of the abdominal wall and a central location from which all quadrants of the abdominal cavity can be visualized. Coming to a Cleveland Clinic location?Hillcrest Cancer Center check-in changesCole Eye entrance closingVisitation and COVID-19 information, Notice of Intelligent Business Solutions data eventLearn more. Am J Obstet Gynecol. The aponeurotic components of the sheath interdigitate in a thickened fibrous midline raphe between the two recti known helpfully as the linea alba (white line). C. The diaphragm is usually opened in a radial fashion with an incision directed toward the esophageal or aortic hiatus. The incision is then carried down to the linea alba using either electrocautery or a scalpel; the decussation of fascial fibers in the upper abdomen serves as an important landmark for the midline. Transverse abdominal access appears to affect pulmonary function less than midline access and may be less prone to rupture. The midline incision allows rapid access to, and adequate exposure of, almost every region of the abdominal cavity and retroperitoneum. Left lumbar approach to the retroperitoneum. 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. Other recovery and complication rates are similar although the transverse incision may look better. See more with MDedge! 1. There is a suggestion that a transverse incision is also less painful but this result is less clear. As the recti have a segmental nerve supply, it can be cut transversely without weakening a denervated . Normal labor and delivery. Abdominal Incisions and Anatomy of the Abdominal Wall Kocher incision. This content does not have an English version. B. This incision is oriented obliquely. The diaphragm is either incised radially toward the esophageal or aortic hiatus or in a curvilinear fashion if less exposure is required. The fascial fibers of the anterior abdominal wall are oriented transversely or obliquely. 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. . 1990;77:626-627. - Medical Finals Question Pack: https://geekymedics.com/medical-student-finals-questions/ TikTok: https://www.tiktok.com/@geekymedics - PSA Question Pack: https://geekymedics.com/psa-question-bank/ 3). 10-6). Episiotomy: Procedure, Advantages, Complications & Healing The subcutaneous tissues are divided to expose the posterior layer of the lumbodorsal fascia. B. Resection of the twelfth rib facilitates exposure. Resection of the xiphoid may afford even better superior exposure when needed. To provide you with the most relevant and helpful information, and understand which For example, when pelvic anatomy is distorted, as with severe endometriosis or sepsis, recognizable anatomy may be found only above the pelvic brim.

Thoracic Incisions Technique: Approach Considerations, Sternotomies Br J Urol. It is an excellent choice when access to the upper abdomen may be necessary, e.g., patients with gynecologic malignancies who may need assessment of the diaphragm, liver biopsy, para-aortic node biopsy, omentectomy, or debulking procedures. The patient is positioned with the operative side elevated 30 to 45 degrees with the knees and hips flexed. This incision is also commonly utilised by vascular surgeons for elective and emergency repair of abdominal aortic aneurysms. Insufflation tubing is then attached to the cannula and the obturator is withdrawn. Retroperitoneal and extraperitoneal approaches can be used for operations on the kidney, ureter, adrenal gland, bladder, splenic artery and vein, vena cava, lumbar sympathetic chain, abdominal aorta, and iliac vessels, and on groin hernias. The incision can be extended beyond the lateral aspect of the rectus muscle if necessary to facilitate exposure. If you are a Mayo Clinic patient, this could 01:16 When to pause chest compressions It is typically associated with little blood loss and does not require transection of muscle fibers or nerves.

The longitudinal incisions that will be reviewed here are the midline (median) and paramedian. 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. Disadvantage: a) Lengthy and time-consuming Oblique incisions They are also known as Thoracoabdominal incisions, these incisions may either be situated in the RUQ or LUQ. This incision also preserves phrenic nerve function and is useful for patients with pulmonary compromise.13.

Division of the rectus and medial portions of the lateral abdominal muscles. Talk to your provider ahead of time and share your concerns about the procedure and your desire to avoid it. These factors are the key determinants of whether the incision will be longitudinal (midline or paramedian) or transverse (Pfannenstiels, Cherneys, or Maylards). The incision is extended obliquely along the line of the eighth interspace just beneath the inferior pole of the scapula (Fig. The midline incision implies a vertical incision through skin, subcutaneous fat, linea alba, and peritoneum. Mayo Clinic does not endorse companies or products. This classically corresponds to the area of maximal tenderness on clinical examination when the appendix has become sufficiently inflamed to cause localised peritonitis. Facebook: http://www.facebook.com/geekymedics A multicenter collaborative study on the use of cold scalpel and electrocautery for midline abdominal incision. Technique for Classical CS - Obstetrical Surgical Skills (Reproduced with permission from Baker RJ, Fischer JE: Mastery of Surgery, 4th ed. Contact your health care provider if the pain gets worse. Nothing should compromise this, and a larger incision or even, on occasion, a second incision, should be created without hesitation if exposure is inadequate. Sometimes your perineum will tear naturally as your baby comes out. 4. 1992;79:988-992. An incision must provide access to the site of abdominal pathology and allow ready extension if greater exposure is required. If the operation requires extension of the wound laterally, this can be accomplished through division of the oblique muscles. This type of tearing extends through the anal sphincter and into the mucous membrane that lines the rectum. Complications that can occur due to an episiotomy include: Its important to note that the complications listed above can also occur with a natural tear. It's hard to prevent perineal tears or an episiotomy since a lot of it is out of your control. 00:23 Key parts of an AED Superiorly, additional access can be obtained by directing the upper portion of the incision along the costal margin toward the xiphoid process (Fig. The peritoneum has been bluntly dissected from the retroperitoneal structures with the preperitoneal fat and soft tissue. Surface markings. The erector spinae muscle is exposed and retracted medially to uncover the twelfth rib and the middle layer of the lumbodorsal fascia. The patient is placed in the corkscrew position on the operating room table to enhance access to both the abdominal and thoracic cavities. A.

Incision selection plays an important role in gynecologic surgery, especially with regard to adequate pelvic access and preservation of abdominal wall function. Additional considerations include certainty of diagnosis, speed of entry, body habitus, presence of previous scars, potential for problems with hemostasis, and cosmetic outcome. The thoracoabdominal incision provides enhanced exposure of upper abdominal organs. information submitted for this request. However, this incision is often more painful and more difficult to repair. Although properly placed transverse incisions can provide exposure of specific organs, they may be limiting when pathology is located in both the upper and lower abdomen. A comprehensive collection of OSCE guides to common clinical procedures, including step-by-step images of key steps, video demonstrations and PDF mark schemes. Laparoscopic incisions may be placed anywhere on the abdominal wall.

Massaging your perineal tissue (area between the vaginal opening and anus) in the weeks leading up to delivery may reduce the chances of tearing or needing an episiotomy. The lower pole of the kidney, ureter, and sympathetic chain are easily identified. Natural tears usually require the same recovery time. 10-2). Br J Surg. . As with open abdominal incisions, laparoscopic access must allow optimal exposure without unnecessarily compromising abdominal wall function or cosmesis. It is commonly used for open appendicectomies. Shaving prior to operation has been associated with an increased rate of surgical site infection and should, therefore, be avoided. health information, we will treat all of that information as protected health It is generally thought to be faster and easier to perform in the case of an emergency classical cesarean section. An elastic defect in this raphe may allow the fascia to stretch and abdominal contents to bulge forward through the resulting divarication of the recti. If the peritoneum is inadvertently entered, it is closed immediately. Accessed Aug. 16, 2018. Twitter: http://www.twitter.com/geekymedics Good access to midline upper GI structures. 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. These vessels should be ligated when encountered. 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. The internal oblique is unique in that its aponeurosis divides into an anterior and posterior leaf, the relevance of which will become clear later. They can tell you if it's normal based on the type and severity of episiotomy you had.

A bilateral subcostal incision affords excellent exposure of the upper abdomen. 10-11). Limited midline incisions are also employed to assist laparoscopic cases such as bowel resections, where the dissection and mobilisation of the specimen to be excised are performed laparoscopically but then a larger port is required for retrieval. Other sites are preferable in specific circumstances (eg, left upper quadrant access in a patient with a previous midline incision). Common examples include the Kocher subcostal incision for biliary surgery, the Pfannenstiel infraumbilical incision for gynecologic surgery, and the McBurney and Rocky-Davis incisions for appendectomy. While this incision can be used for any surgical procedure, it is especially appropriate when the diagnosis is uncertain and the exact procedure or extent of surgery is unclear.
