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. If you've already had an. 6. If the peritoneum is inadvertently entered, it is closed immediately. 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. A transverse incision is a useful laparotomy technique for use in paediatric patients who have not yet developed deep subphrenic or pelvic recesses, and in whom the surgeon, therefore, does not need the ability to extend the incision longitudinally as afforded by the midline incision. 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). There is a problem with Types of episiotomy incisions. Prevention of wound dehiscence. 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. If you're planning a vaginal delivery, here's what you need to know about episiotomy and childbirth. They derive their blood supply from the superior and inferior epigastric arteries from the internal thoracic and external iliac arteries respectively, and their innervation from the anterior rami of spinal nerve roots T7-T12. 00:00 Introduction 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. Box 2. The peritoneum itself is best divided with scissors or scalpel to avoid coagulation injury to underlying intra-abdominal organs. The high combined incidence of surgical site infection, wound dehiscence, and hernia formation suggests a dominant contribution of wound complications to surgical morbidity. B. Peritoneum is retracted medially by blunt dissection, which exposes the psoas muscle and gonadal artery and vein, shown anterior to the ureter. Please write a single word answer in lowercase (this is an anti-spam measure). 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. With the posterior approach, dissection is performed entirely in the retroperitoneal space. These are sharply divided, and the appendix and cecum are exposed (Fig. Donaldson DR, Hegarty JH, Brennan TG, et al. It is typically associated with little blood loss and does not require transection of muscle fibers or nerves. Surface markings. 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. Other recovery and complication rates are similar although the transverse incision may look better. 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. The diaphragm is either incised radially toward the esophageal or aortic hiatus or in a curvilinear fashion if less exposure is required. Kearns SR, Connolly EM, McNally S, McNamara DA, Deasy J. Randomized clinical trial of diathermy versus scalpel incision in elective midline laparotomy. Disadvantages include disruption of the innervation to the rectus lying medially. https://www.uptodate.com/contents/search.

This can be achieved using an open or closed technique. Superiorly, additional access can be obtained by directing the upper portion of the incision along the costal margin toward the xiphoid process (Fig. TikTok: https://www.tiktok.com/@geekymedics Recently, J- or L-shaped incisions have gained popularity for exposure of the upper quadrants of the abdomen and for hepatic resection in particular. (Reproduced with permission from Baker RJ, Fischer JE: Mastery of Surgery, 4th ed. 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. Like midline incisions, paramedian incisions obviate division of nerves and the rectus muscle and may be made in the upper or lower abdomen. If hair at the surgical site will interfere with accurate wound closure or precludes easy application of the sterile preparation, the use of clippers is preferred to a razor.7 A variety of antiseptic solutions are commonly used to prepare the skin, including povidone-iodine, alcohol, and chlorhexidine. Experts believed an incision would heal better than a natural tear. A sitz bath involves filling a sitz bathtub (it usually goes over your toilet) or bathtub with warm water and submerging your genital area in the water. If the patient is obese or if extension of the incision is anticipated, the incision should be placed obliquely, allowing ready lateral extension. Terms in this set (32) What is a ventral midline incision, and when is it used? 1. The incision can also be extended superiorly as far as the costal margin if necessary. Cleveland Clinics Ob/Gyn & Womens Health Institute is committed to providing world-class care for women of all ages. Abdominal entry is confirmed by digital palpation. 7th ed. Traditionally, vertical incisions were used for caesarean delivery [ 36 ], but the disadvantages of a vertical incision are greater risk of postoperative wound dehiscence and . 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. 10-9). immunocompromised, smoking, obesity, jaundice, diabetes, steroid use, previous radiotherapy, vascular disease), Procedure-specific (i.e. The longitudinal incisions that will be reviewed here are the midline (median) and paramedian. Whether patients are referred to us or already have a Cleveland Clinic ob/gyn, we work closely with them to offer treatment recommendations and follow-up care to help you receive the best outcome. Mediolateral: An angled or diagonal incision. Most of the fibres, crossing the linea alba in a medio-caudal and medio-proximal direction, are cut transversely. Arch Surg. 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. It's not as widely used as it once was, but there are some instances where your obstetrician performs an episiotomy. There are two main types of incisions: Median (midline): A vertical (up and down) incision beginning at the vaginal opening extending toward the anus. Am J Surg.

Origins of the celiac, superior mesenteric, left renal, and inferior mesenteric arteries are shown. Review/update the A. Paramedian incision: dissection of the rectus muscle from the anterior rectus sheath. Purpose: Both midline and transverse abdominal incisions are used for exposing the infrarenal aorta. The solution should, therefore, be applied several minutes prior to incision to maximize its efficacy. Chapters: 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. These instances include: The latest research suggests it's better to let the perineum tear naturally. Episiotomy: Procedure and repair techniques. They provide entry to the liver, lungs and spleen, as well as to the stomach and esophagus. Cochrane Database of Systematic Reviews. C. Dividing in the midline and entering the peritoneal cavity.

A comprehensive collection of OSCE guides to common clinical procedures, including step-by-step images of key steps, video demonstrations and PDF mark schemes. 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. Alternatively, an oblique upper abdominal incision can be used and extended directly into the thoracic portion of the incision. Importantly, the rectus muscle has a segmental innervation derived from intercostal nerves that enter the rectus sheath laterally. A. 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. Infection is possible. 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. Alternatively, vertical incisions may be placed in a paramedian position, an approach that was previously more popular than it is today but continues to have its proponents. It is also used by general and urological surgeons for some pelvic procedures such as radical open prostatectomy or cystectomy. Wound infection after abdominal incision with scalpel or diathermy.

Longer incisions should be avoided, however, because they result in significantly more bleeding and sacrifice of nerves that may lead to muscle atrophy and weakening of the corresponding area of the abdominal wall. Due to the perpendicular nature of vertical/midline incisions with reference to the oblique muscle layer, it cuts medial to they might be associated with more pain due to nerve damage as nerves run in a parallel fashion to the oblique muscle layer crossing the midline.
