01:16 When to pause chest compressions 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. This incision may be modified to follow the horizontal Langers lines for improved cosmesis. Sign up for free, and stay up to date on research advancements, health tips and current health topics, like COVID-19, plus expertise on managing health. The intercostal muscles of the eighth interspace are divided to allow entry into the chest cavity, and the incision is extended across the costal margin, which is divided with a scalpel. A. 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. The research is mixed and providers aren't entirely sure stretching the perineum works, but it's usually harmless. It may be mirrored on the contralateral side to provide access to the spleen or performed bilaterally as a Rooftop incision to provide efficient access to organs such as the pancreas and biliary tree within the transpyloric plane (see below). 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. The subcutaneous tissues are divided to expose the posterior layer of the lumbodorsal fascia. 00:00 Introduction The flank approach has been recommended for . B. Paramedian incision in transverse section. The skin incision is oriented obliquely and extends from approximately 2 cm above the anterosuperior iliac spine to a point just lateral to the pubic symphysis (Fig. The peritoneum is opened at cephalic pole of incision; The peritoneal incision is expanded longitudinally, slightly off midline to avoid urachus; Vertical Paramedian Incision. The open approach involves the creation of a small incision, generally 1.5 cm, through which the abdominal fascia is grasped with straight clamps and elevated toward the wound. - 700+ OSCE Stations: https://geekymedics.com/osce-stations/ 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. The lower midline incision (ie, below the umbilicus) provides exposure of lower abdominal and pelvic organs. 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. MDedge: Keeping You Informed. The abdomen is tilted approximately 45 degrees from the horizontal plane, and the thorax is oriented in full lateral position (Fig. Can vaginal tears during childbirth be prevented? . information is beneficial, we may combine your email and website usage information with These factors are the key determinants of whether the incision will be longitudinal (midline or paramedian) or transverse (Pfannenstiels, Cherneys, or Maylards). Did clinic use proper equipment for resuscitation? 1976;48:469.-. Transverse and oblique incisions generally follow Langers lines of tension and allow a more cosmetic closure than do vertical incisions. 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. Some things you can do at home to relieve your discomfort are: Talk to your midwife or obstetrician about what you can expect and what activities you should avoid during the recovery period. Br J Surg. Epigastric midline incision: surface markings. Expand this cut slightly off midline to avoid the urachus yet adequately expose the peritoneal cavity (Figure 2). Box 2. 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: In the patient who has had prior abdominal surgery, the cosmetic advantages of reentering the abdomen through a preexisting scar must be balanced against the challenges associated with dissection in a reoperative field. This produces a distinct ridge in the midline on increasing intra-abdominal pressure that is often mistaken for an epigastric hernia. The high combined incidence of surgical site infection, wound dehiscence, and hernia formation suggests a dominant contribution of wound complications to surgical morbidity. Wound dehiscence following midline laparotomy is a particularly distressing event for the patient, whereby classically a serosanguinous discharge is noted from the wound 7-10 days postoperatively, and a day or so later the whole wound may burst open and spill the patients intestines into their lap. 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. Chapters: In certain situations, an episiotomy helps reduce the risk of a bad natural tear. 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. A midline incision is easier to repair, but it has a higher risk of extending into the anal area. information highlighted below and resubmit the form. 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. 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. The length of the incision will vary depending on the procedure, exposure required and the surgeon's experience. DO NOT perform any examination or procedure on patients based purely on the content of these videos. The avascular linea alba affords the vertical midline its superior flexibility. The fascia and then peritoneum are divided under direct vision. This incision begins at the xiphoid, extends to just above the umbilicus, and then extends laterally to the right. 10-9). A collection of free medical student quizzes to put your medical and surgical knowledge to the test! Please write a single word answer in lowercase (this is an anti-spam measure). Normal labor and delivery. Disadvantages include the risk of injury to the ilioinguinal and iliohypogastric nerves. Outcomes included analgesic use, pulmonary function, complication rates and hospital stay. Superficial to the external oblique lies Scarpas membranous fascia, Campers subcutaneous fatty layer, and the skin. This article discusses the anatomy of the abdominal wall, anatomy of the rectus sheath and common abdominal surgical incision types (midline, paramedian, pararectal, Gridiron, Lanz, Pfannenstiel, transverse, Kocher). The falciform ligament of the liver is commonly encountered if the incision is made to the right of the midline, and the tendinous intersections must be divided on the chosen side in order to access the peritoneum. With the posterior approach, dissection is performed entirely in the retroperitoneal space. D. Opening midline. Accessed Aug. 16, 2018. Provided that the anterior and posterior fascia is closed, the rectus muscle can be divided transversely without significantly compromising the integrity of abdominal wall. Use of this Web site is subject to the medical disclaimer. It's common to feel pain and soreness for the first few weeks and have some discomfort with sex (once you're given the OK for intercourse).

TikTok: https://www.tiktok.com/@geekymedics Origins of the celiac, superior mesenteric, left renal, and inferior mesenteric arteries are shown. If no mass is palpable, the incision is centered over McBurneys point at the junction of the middle and outer thirds of the line between the umbilicus and the anterior superior iliac spine. Once free, the rectus muscle is retracted laterally. 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. If further exposure is necessary, the wound can be enlarged by dividing the rectus sheath, retracting the rectus muscle medially, and extending the peritoneal defect. If we combine this information with your protected Disadvantages include the risk of injuring the superior epigastric vessels, and lateral extension of the incision risks disruption of intercostal nerves. Witch hazel helps to soothe the area and relieve irritation. ), 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. B. Midline or transverse laparotomy? 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. Johnson CD, Serpell JW. C. The diaphragm is usually opened in a radial fashion with an incision directed toward the esophageal or aortic hiatus. 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. The Lanz incision was designed to be more cosmetically subtle than the gridiron, with the benefit that it may be hidden beneath the bikini line but the disadvantage of commonly severing the ilioinguinal and iliohypogastric nerves. 10-10A). The attachments of the erector spinae to the twelfth rib are divided with electrocautery; the vessels and nerves that penetrate the fascia are secured with clamps and ligated. The chest muscles and abdominal wall are then closed in layers. 10-10B). The incidence of incisional hernias and wound dehiscence has been reported to be lower, but these studies are not randomized. The suspected position of the appendix and the thickness of the abdominal wall influence the placement of the incision as well as its length. Perineal techniques during the second stage of labour for reducing perineal trauma. We offer women's health services, obstetrics and gynecology throughout Northeast Ohio and beyond. 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. 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. Incisions through the anterolateral wall will, therefore, breach the following structures: As the fibres of the lateral abdominal wall muscles progress medially they give rise to fibrous sheets of tissue known as aponeuroses, allowing a far wider area of insertion than would be achievable with the typically round tendons seen on muscles of the appendicular skeleton. The left-sided subcostal incision is used less often, mainly for splenectomy or left upper quadrant masses. The skin incision is placed in the interspinous crease above the symphysis pubis. Use of the Pfannenstiel incision, which marries a cosmetically acceptable low transverse abdominal incision with a vertical midline fascial incision, also presumes that the scope of the pathology has been accurately assessed prior to surgery.If more exposure is required because this is not so, the surgeon's ability to make the incision larger is limited. Needing an episiotomy is not as common as it once was. To avoid injuries to the bladder, the peritoneum is entered in the upper portion of the incision. 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. Philadelphia, PA: Lippincott Williams & Wilkins; 2001.). 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. These advantages and disadvantages are summarized in Table 84.1 (for low transverse incisions) and Table 84.2 (for high transverse incisions). - 150+ PDF OSCE Checklists: https://geekymedics.com/pdf-osce-checklists/ At the conclusion of the procedure, the retroperitoneal fat and viscera fall back into place and the muscles of the abdominal wall are reapproximated in layers. Conversely, modulated (coagulating) current coagulates the tissue with heat-producing char over a large area, and tissue injury often extends beyond the char. The recti are interrupted by three paired tendinous intersections anchoring them to the anterior sheath, broadly found close to the xiphisternum, at the level of the umbilicus and then halfway between the two. Accessed Aug. 1, 2018. It is often employed for surgery on the iliac arteries and for kidney transplantation. B. Peritoneum is retracted medially by blunt dissection, which exposes the psoas muscle and gonadal artery and vein, shown anterior to the ureter. If you have an episiotomy, it's because it was the safest for you or your baby. Kocher incision. A mediolateral incision (shown at right) is done at an angle. The patient is positioned with the operative side elevated 30 to 45 degrees with the knees and hips flexed. Traditionally, vertical incisions were used for caesarean delivery [ 36 ], but the disadvantages of a vertical incision are greater risk of postoperative wound dehiscence and . MidlineTechnique. 10-2). Sanders RJ, DiClementi D. Principles of abdominal wound closure. 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. - Medical Finals Question Pack: https://geekymedics.com/medical-student-finals-questions/ Once the underlying transversalis muscle is exposed, it is split to reveal the transversalis fascia and peritoneum. The midline incision implies a vertical incision through skin, subcutaneous fat, linea alba, and peritoneum. . Here, a guideline to the advantages and disadvantages of commonly used longitudinal and transverse incisions and the procedures for which they are best suited. The incision is extended obliquely along the line of the eighth interspace just beneath the inferior pole of the scapula (Fig. Arch Surg. Running closure of the fascial layers can then be undertaken. Structures within the transpyloric plane: Complications are best considered in terms of specificity and chronicity; i.e. It is typically associated with little blood loss and does not require transection of muscle fibers or nerves. Laparoscopic incision Prior to incision, the surgical field is prepared with antiseptic solution and draped in order to reduce skin bacterial counts and the likelihood of subsequent wound infection. The diaphragm is either incised radially toward the esophageal or aortic hiatus or in a curvilinear fashion if less exposure is required. 00:00 Introduction (Reproduced with permission from Baker RJ, Fischer JE: Mastery of Surgery, 4th ed.

Wiser Chair for Gynecologic Surgery and Dr. Trenhaile is assistant professor of OBG, department of OBG, at the University of Mississippi Medical Center in Jackson. Transverse incisions create less tension on the opposing skin edges because the incision follows Langers lines. As with open abdominal incisions, laparoscopic access must allow optimal exposure without unnecessarily compromising abdominal wall function or cosmesis. The skin incision may be shorter than depicted in thinner patients or if an abscess is to be drained. After a preparation of the ventral abdominal wall, a midline incision of 30 cm on linia alba was performed (F ig. Disadvantages include the risk of injury to the ilioinguinal and iliohypogastric nerves. This study compares intraperitoneal transverse and midline incisions with .

This common approach may be used to access most intra-abdominal structures, including those of the retroperitoneum. The medial aspect of the anterior rectus sheath is then dissected away from the rectus muscle to its medial edge (Fig. include protected health information. Philadelphia, PA: Lippincott Williams & Wilkins; 2001.). Routine episiotomies are no longer recommended. The lower abdominal midline incision should be employed if optimal exposure is desired.

These incisions are reserved for circumstances in which an operation cannot safely be performed through an abdominal incision, as they are theoretically associated with increased morbidity relating to a more difficult pulmonary recovery and risk of phrenic nerve injury. 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. Alternatively, an oblique upper abdominal incision can be used and extended directly into the thoracic portion of the incision. Most of the fibres, crossing the linea alba in a medio-caudal and medio-proximal direction, are cut transversely. 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. 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 abdominal cavity is an ovoid space bounded cephalad by the diaphragm and inferior thoracic margin, caudally by the pelvic brim, posteriorly by the lumbar spine along with quadratus lumborum, psoas major and iliacus, and anterolaterally by the retaining musculature of the abdominal wall.

This may help make the tissue more flexible. 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. Some also believed it could prevent complications like urinary incontinence and pelvic floor dysfunction. They provide entry to the liver, lungs and spleen, as well as to the stomach and esophagus. However, when it comes to dissecting the underlying subcutaneous tissues, the debate continues over whether a scalpel or electrosurgery is best. Pfannenstiel J.

The midline incision implies a vertical incision through skin, subcutaneous fat, linea alba, and peritoneum. More wound infections were seen with transverse incisions.3, Controversy also persists regarding the relative advantages of midline versus paramedian incisions. Risk factors for wound dehiscence can be: Late complications include the development of an incisional hernia, where the underlying peritoneum and associated contents protrude through residual defects in the abdominal wall, and the formation of dense fibrotic intra-abdominal band adhesions. Abdominal Incision: Vertical Midline. If you are a Mayo Clinic patient, this could Philadelphia, PA: Lippincott Williams & Wilkins; 2001. After a small opening is created in the midline, it is enlarged to accommodate 2 fingers that are then used to protect the underlying viscera as the peritoneum is further divided along the length of the wound (Fig. The legendary superior strength of the Pfannenstiel incision: a myth?

Immediate complications of a midline laparotomy incision may include anaesthetic difficulties, haemodynamic instability, primary haemorrhage from cut vessels and iatrogenic injury to surrounding tissues and viscera. Episiotomy risks Episiotomy recovery is uncomfortable. Initiate the midline as a low abdominal incision (approximately 2 cm above the pubic symphysis), cutting along the linea alba. An episiotomy is a surgical procedure where a small incision is made in the area between your vagina and anus (perineum) during childbirth. Anterolateral thoracoabdominal incision. A left thoracoabdominal incision is useful for access to the left hemidiaphragm, gastroesophageal junction, gastric cardia and stomach, distal pancreas and spleen, left kidney and adrenal gland, and aorta. Episiotomy Procedures Advantages and Complications. It is also used by general and urological surgeons for some pelvic procedures such as radical open prostatectomy or cystectomy. .With the animal on its back, an incision is made in the center of the abdomen. The intercostal neurovascular bundle should now become visible directly below the bed of the resected twelfth rib. Exposure of the fascia is often enhanced with the use of S-shaped retractors. Paramedian incisions are vertical incisions placed either to the right or left of the midline on the abdominal wall. E. Peritoneum opened. D. The diaphragm can alternatively be opened with a hemielliptical incision 2 to 3 cm from the lateral chest wall; this incision preserves phrenic nerve function, which is of particular importance in patients with impaired pulmonary function.
