Common causes of abdominal wall pain include nerve entrapment, hernia, and surgical or procedural complications. Having come this far in the examination, if either the patient or the examiner needs further convincing of the ACNES diagnosis, local injection of an anesthetic agent is appropriate (described later under Treatment). They are commonly known as abdominals or 'abs' muscles and are present in the pair at the front wall of the abdomen. Application of an elastic bandage for counterpressure may be helpful. The Rectus Abdominis makes up the top layer of your abdominal muscles, commonly referred to as your "six-pack." It is two flat and parallel muscles separated by linea alba (a connective tissue). Abdominal wall pain should be suspected in patients with no symptoms or signs of visceral etiology and a localized small tender spot. The anterior exits are easiest to feel and are often best felt with the patient standing and pushing the abdomen out: T10 is at the lateral edge of the rectus margin at the level of the umbilicus; T12/L1 is at the level of the internal inguinal ring; and T11 is halfway between T10 and T12/L1 at the rectus margin, which is closer to the midline for these last two points. The management of pain. Introduction Early descriptions about abdominal wall innervation date back to 1916, when Walmsley first described thoracolumbar nerves focusing only on the superior ones [ 22 ]. It can be used to detect masses, abscesses, hematomas, tissue edema, and slipping rib syndrome. 1. At the costal margins, the thoracic nerves T7 to T11 enter this neurovascular plane of the abdominal wall, travelling along this plane to pierce the posterior wall of the rectus sheath as anterior cutaneous branches supplying the overlying skin. Regional blocks of the anterior abdominal wall can significantly help with intraoperative and postoperative analgesia. Sequentially as the needle is introduced, the clinician feels resistance to the needle from the patients skin, the nonresistant texture of the subcutaneous fat, and then mild resistance to the needle from the aponeurosis and fatty plug. In many patients, one injection gives prolonged relief or may sufficiently reassure younger patients that the condition is benign and will not require another visit unless another injection is needed for pain relief. Intercostal Nerves 2. Their aponeuroses fuse together, forming the rectus sheath that encloses the rectus abdominis (except the posterior quarter inferior to the arcuate line), the inguinal ligament inferiorly, the linea semilunaris lateral to the rectus abdominis, and the linea alba at the midline.15 These aponeuroses, as well as the navel and any surgical incision sites, are areas prone to hernia formation. Occasionally, a patient reports relief from pain upon arriving home. Cotton and pinprick technique can be used to check for hypoesthesia or hyperesthesia around the pain site, and Knockhaert23 notes that electromyelographic studies of the affected nerve show abnormalities in 60% of patients studied (although this author23 admitted that the procedure has low sensitivity). Inclusion in an NLM database does not imply endorsement of, or agreement with, In: Bonica JJ, editor. Philadelphia: Lea & Febiger; 1990. p 125482.24). Anything that increases pressure behind the abdominal wall can cause the bundle to herniate through the fibrous ring and aponeurotic opening. The pain may radiate when the patient twists, bends, or sits up. Motor: Intercostal nerves (T7- T11), Subcostal nerve (T12) . Spigelian hernias, which are rare defects in the transversus aponeurosis occurring at the junction of the rectus abdominis and linea semilunaris, often occur at or inferior to the arcuate line because the posterior rectus sheath is lacking in this area. National Library of Medicine Precise application of an ice cube wrapped in a thin washrag can help by acting as a local anesthetic and by reducing swelling around the nerve. The rectus sheath block was first described in 1899 and was initially used for the purpose of abdominal wall muscle relaxation during laparotomy before the adjunct of neuromuscular block.5 Now, it is used for analgesia after umbilical or incisional hernia repairs and other midline surgical incisions. Schleich first described the use of bilateral rectus sheath blocks (BRSBs) in 1899, with the aim of providing muscle relaxation and analgesia of the abdominial wall by blocking the terminal branches of the thoracolumbar nerves within the substance of the rectus abdominis muscle (RAM). Because the testicles are located in the externally positioned scrotal sac, men have the advantage of being able to examine their testicles easily, whereas womens ovaries, being located inside the abdomen, are inaccessible to examination except by medical personnel. The muscle is divided into compartments by the midline linea alba, paramedian linea semilunaris, and transverse fibrous bands. Although any main branch of the nerve may become symptomatic, the anterior branches are most likely to be affected, because stretching of the nerve is greatest at the point most distant from its origin (ie, the spinal cord). The rectus abdominis muscle is inserted between the aponeuroses of the external and internal obliques and transversus abdominis muscles that form the rectus sheath. If for any reason the pain is recurrent or persistent, it can be treated by destroying the symptomatic portion of the nerve. How often does stress provoke the pain? The patient's ability to localize pain with a fingertip is an element of the history that is highly suggestive of abdominal wall pain.11 Patients with abdominal wall pain often have comorbid obesity.12 Validated screening tools can also be helpful; a systematic 18-item patient questionnaire (Table 3) can be used to differentiate anterior cutaneous nerve entrapment syndrome from irritable bowel syndrome, with a score of 10 or higher having 94% sensitivity and 92% specificity for anterior cutaneous nerve entrapment syndrome.6. Posterior foramina are found in the groove between the paravertebral muscles and the more lateral back muscles. Trapezius 2. Accessory branches perforate the muscle wall above and below the main branches but also exit from adjacent muscle mass. Copyright 2023 American Academy of Family Physicians. Regional analgesia of the abdominal wall can provide good analgesia for a variety of surgical operations especially when used as part of a multimodal technique (Table1). In practice, performing blocks of the anterior abdominal wall has traditionally relied on landmark techniques and detection of fascial pops to identify the correct location and fascial plane for needle insertion and local anaesthetic deposition. Ilioinguinal/iliohypogastric blocks in children: where do we administer the local anaesthetic without direct visualisation? A properly administered local injection of an anesthetic agent completely relieves the pain of ACNES. This syndrome is characterized by the entrapment of the cutaneous branches of the lower thoracoabdominal intercostal nerves at the lateral border of the rectus abdominis muscle, which causes severe, often refractory, chronic pain. It acts to flex the spinal column, tense the anterior wall of the abdomen and assist in compressing the contents of the abdomen. In addition, the paired rectus abdominis muscle forms a muscle layer either side of the midline (Fig. Published by Oxford University Press on behalf of the British Journal of Anaesthesia. To do this, the examiner should practice finding these depressions on his or her own abdomen and on someone else. One of my male patients with ACNES reported that he had pain intermittently for 47 years.5 He had long ago decided that the pain was of no great consequence but was happy to hear my explanation of its cause. Use of corticosteroid drugs is theoretically valuable because some inflammation is seen in ACNES; however, injection of corticoid drugs into muscles can sometimes cause considerable pain, and tissue atrophy can occur with repeated injection. Chronic ACNES patients suffer considerable anxiety and worry that they may have some horrible condition as yet undiscovered. It will also send motor branches to the inferior portions of the transversus abdominis, external oblique, and internal oblique muscles. How often do you feel an urgent need for bowel movement without producing stool (incomplete defecation)? The site is secure. Language links are at the top of the page across from the title. This article updates a previous American Family Physician article on abdominal wall pain with emerging data on point-of-care ultrasonography and surgical intervention.8. Local anaesthetic is injected between the rectus abdominis muscle and the posterior rectus sheath. The fatty plug varies in size from 2 mm to 2 cm, depending on how dilated the aponeurotic openings have become. The clinician can then replace the abdominal hand on the tender spot and retract the vaginal finger to see whether the pain changes. Too much traction on the bundle from behind or from pulling in front will cause the bundle to be strummed against the ring, which then causes irritation and swelling even before herniation occurs. Along its course, the iliohypogastric nerve will innervate the skin over the buttocks, ileum, and skin overlying the inferior portion of the rectus abdominis muscle. Applegate WV. Accessory nerve exits are located 2 mm to 3 mm above or below the main branch exits or over adjacent muscle and usually cannot be palpated with certainty unless symptomatic. They have the same arrangement as the upper ones as far as the anterior ends of the intercostal spaces, where they pass behind the costal cartilages, and between the Obliquus internus and Transversus abdominis, to the sheath of the Rectus abdominis, which they perforate. Because repeat injection requires only a few minutes in patients who have already been evaluated, these patients may often be scheduled for a same-day appointment, even to evaluate new associated symptoms. 13. Supraclavicular Nerve 2. Ultrasound guidance can assist in localization of tissue planes and aid successful nerve block. This article discusses in detail how to identify the muscular neuroforamina by palpation as well as the specific technique for injecting them. The subcostal nerve runs initially under the 12th rib and then between the transverse and internal oblique muscles to the outer edge of the rectus sheath. He is an Associate Clinical Professor at UCSD Medical School in San Diego, CA. The most common cause of abdominal wall pain is nerve entrapment at the lateral border of the rectus muscle; this is known as anterior cutaneous nerve entrapment syndrome. The main function of this muscle is to move the body between the ribcage and the pelvis. *TAP blocks are unlikely to provide complete analgesia for upper abdominal incisions. Those evaluations generally are nondiagnostic, and lingering pain can become frustrating to the patient and clinician. Function of the Rectus Abdominis The rectus abdominis muscle is an essential postural muscle. Incisional hernias can occur wherever there is an incision. Anterior cutaneous nerve entrapment syndrome should be suspected in patients with a localized small tender spot at the lateral edge of the rectus abdominis. In children, the use of lower doses of local anaesthetic has been described with ultrasound guidance compared with the landmark technique.5. Beginning in 1792 with J P Franks description of the condition he named peritonitis muscularis,1 a sampling of pertinent medical literature on this subject29 shows how often the subject has been written about over the years. 17. All rights reserved. In my experience, using 1 mL of absolute alcohol mixed with 0.5 mL of a 2% lidocaine solution achieves a good result and causes minimal local pain. Is the pain just lateral to the midline of the abdomen? How often do you have pain when coughing, sneezing, or squeezing? Concern about their gonads is uppermost in the minds of young people who have recently matured sexually. The nerve runs in the plane between the internal oblique and transversus abdominis muscles and later pierces the internal oblique to lie between this muscle and the external oblique before giving off cutaneous branches. I strongly suspect that the anatomic areas that Janet Travell called trigger points27 are actually areas where sensory nerves are trapped in muscles that are in spasm. The injection is made at a point 2 cm medial and 2 cm cephalad to the anterior superior iliac spine using a short-bevelled needle advanced perpendicular to the skin. 16. Young women often express concern about their ovaries, kidneys (the bladder is meant), or both. Myofascial pain and dysfunction: the trigger point manual. The aim of this technique is to block the terminal branches of the 9th 10th, and 11th intercostal nerves which run in between the internal oblique and transversus abdominis muscles to penetrate the posterior wall of the rectus abdominis muscle and end in an anterior cutaneous branch supplying the skin of the umbilical area. Tung AS, Tenicela R, Giovanitti J. Rectus abdominis nerve entrapment syndrome. In fact, the most common cause of abdominal wall pain is nerve entrapment at the lateral border of the rectus abdominis muscle;3,5,8,9,12 Carnett,3 in the early 20th century, called this syndrome intercostal neuralgia and claimed to have seen three patients per week with this diagnosis and as many as three per day in consultation sessions. The onset of the sensory block appears to be relatively slow, taking up to 60 min to reach maximal effect,3 so ideally the block is placed at the start of surgery to give adequate time for the onset of sensory analgesia. Thomson WH, Dawes RF, Carter SS. Intercostal neuralgia as a cause of abdominal pain and tenderness. The placement of the needle and local anaesthetic too deep may result in block failure and inadvertent femoral nerve block.6 Injection into the peritoneal cavity will lead to failure of the block and may risk bowel perforation. Diagnostic procedures for these patients are ultimately a matter of clinical judgment, but certainly clinicians and patients can be spared much trouble if the diagnosis of ACNES is established at the first visit. Scar or suture around the nerve in front of the rectus1618 can directly compress the nerve or place it under further traction. With the posterior wall of the rectus sheath lying superficial to the peritoneal cavity, needle misplacement may lead to complications. The acute pain is described as localized, dull, or burning, with a sharp component (usually on one side) radiating horizontally in the upper half of the abdomen and obliquely downward in the lower abdomen. Persistent abdominal pain. ACNES-related pain is well localized and usually affects only one side. Complications include block failure, intravascular injection, or injection into the peritoneal cavity, with associated risks of damage to bowel and other abdominal viscera. The https:// ensures that you are connecting to the Murray GR. Mehta4 and McGrady17 used a Teflon-coated needle with exposed tip to locate the nerve by electrical stimulation. Use of More Specific Terminology May Assist in Better Diagnosis of Abdominal Wall Injuries. Chronic abdominal wall pain: a frequently overlooked problem. We describe our approach for an anterior . It's named after the straight, vertical direction of its fibers relative to the midline of the body. For Permissions, please email: journals.permissions@oxfordjournal.org, Rectus sheath block (bilateral); TAP block (bilateral)*, Hysterectomy/LSCS via Pfannenstiel incision, IL and IH (bilateral); TAP block (bilateral), Copyright 2023 The British Journal of Anaesthesia Ltd. After learning to locate the nerve as described here, clinicians can place the injection accurately in minutes without using a nerve locator. Neurological factors in chronic pelvic pain: trigger points and the abdominal pelvic pain syndrome. Knockaert DC, Boonen AL, Bruyninckx FL, Bobbaers HJ. The examiner now must confirm that the point located by the patient is actually a nerve exit. These openings are in the vertical groove found at the junction between the back and abdominal muscles. 2). Pain originating from the abdominal wall has been described for nearly 100 years 1 but did not receive much attention until 1926, when a simple bedside test was proposed.2 Case reports in the early 1970s suggested that nerve entrapment could be the cause of abdominal wall pain and was able to be successfully treated with local injections.3,4 More recently, the consensus has been that abdominal wall pain is commonly unrecognized, overlooked, underdiagnosed, and understudied.511, The prevalence of abdominal wall pain in the general population and primary care settings is not known, but it ranges from 5% to 67% in patients referred to subspecialists.1214 A study of 100 consecutive patients referred to a pain clinic by gastroenterologists for chronic abdominal pain management found that 43 had abdominal wall pain, and that many were initially misdiagnosed with functional abdominal pain, irritable bowel syndrome, or a psychiatric disorder.13. Good postoperative analgesia and a decrease in morphine requirements for up to 48 h after operation have been demonstrated after a variety of surgeries including open colorectal surgery, retropubic prostatectomy, abdominal hysterectomy, and Caesarean section. The diagnosis of nerve entrapment in a scar is suggested by exacerbation of the pain from pinching the scar or by moving the scar across the underlying muscle. Because of the relatively high failure rate of local anesthetic injection, a combination of local anesthetic and other agents such as corticosteroids, onabotulinumtoxinA (Botox), and phenol are sometimes used. Kopell and Thompson13 stated that peripheral nerve entrapment occurs at anatomic sites where the nerve changes direction to enter a fibrous or osseofibrous tunnel or where the nerve passes over a fibrous or muscular band and that entrapment can be at these sites because mechanically induced irritation is most likely to occur at these locations. In addition to the Carnett test, other components of the physical examination include a pelvic examination for women with lower abdominal pain; a neurologic examination, including sensory dermatome determination; muscle strength testing; a thoracic spine examination; and detection of abdominal defects, masses, or bulging. government site. A suggestive medical history should direct the examiner to precisely locate the tender spot by asking the patient, Where exactly is the pain? The patient usually responds by placing several fingers over the area, whereupon the examiner says, Show me with one finger. As patients place a fingertip on the exact spot, pushing a little harder to find it, they usually say, Right here! and flinch as the tender spot is pressed. Understanding the anatomy of the anterior abdominal wall will aid clinicians in diagnosing and treating abdominal wall pain. The information given in this article should make that early diagnosis of ACNES possible. Search for other works by this author on: Philadelphia, PA: Lippincott Williams and Watkins, Rectus sheath block: successful use in the chronic pain management of pediatric abdominal wall pain, Transversus abdominis plane block: a cadaveric and radiological evaluation, Anatomical considerations of the pediatric ilioinguinal/iliohypogastric nerve block, Ultrasonography-guided rectus sheath block in paediatric anaesthesiaa new approach to an old technique. Pain resolution also occurs in about 20% to 30% of patients with anterior cutaneous nerve entrapment syndrome.5, Electromyelography can be helpful in cases of suspected radiculopathy or neuropathy. 52 Rectus Sheath Block. A positive Carnett test, in which tenderness stays the same or worsens when the patient tenses the abdominal muscles, suggests abdominal wall pain. The triangle is identified just anterior to the lattisimus dorsi muscle and a blunt tipped, short-bevelled needle is placed perpendicular to the skin immediately cephalad to the iliac crest. Applegate WV, Buckwalter NR. An algorithm for the evaluation of abdominal wall pain is presented in Figure 3.11. With the patient lying supine, a point is identified 23 cm from midline, slightly cephalad to the umbilicus at the apex of bulge of the rectus abdominis muscle. The clinician must first decide whether further evaluation is justified. Herniation of the bundle through the ring due to too much pressure from behind or from pulling from in front will compress the bundles vessels and the nerve itself. In addition, each time a patients abdomen is examined for any reason, the examiner should feel for these aponeurotic openings; their size differs widely among persons. In trigger point injection, 5 to 10 mL of 1% to 2% lidocaine is injected deep into the fascia and muscle at the point of maximal tenderness (see video below). Local anesthetic injection with or without corticosteroids can diagnose and treat abdominal wall pain caused by nerve entrapment. If this is the case, the nerve should be severed at the front of the muscle to release distal traction. For full access to this pdf, sign in to an existing account, or purchase an annual subscription. . The key to understanding nerve blocks of the abdominal wall is an understanding of the anatomy. Federal government websites often end in .gov or .mil. This instruction is particularly important for older patients. Does it feel like the pain originates just beneath the skin? A history of multiple abdominal operations should raise suspicion about ACNES. Technique is critical for both diagnosis and treatment, and the tendency is to inject too deeply. Using blocks of the anterior abdominal wall can be a useful addition in ambulatory surgery to improve the quality of analgesia and to reduce postoperative opioid requirements. The abdominal cutaneous nerve entrapment syndrome. I tried this technique with several patients and found the procedure cumbersome and time-consuming. T6 and T7 are located where their respective ribs meet the edge of the rectus muscle. In this article, we aim to describe the techniques and applications for abdominal wall nerve blocks, including the ilioinguinal, iliohypogastric, rectus sheath, and transversus abdominis plane (TAP) blocks. The rectus abdominis is a long strap muscle that extends the entire length of the anterior abdominal wall. Only once have I reinjected alcohol into a patient who had only partial relief from the previous injection. Abdominal wall pain is an umbrella term that comprises many etiologies, the most common of which is benign nerve entrapment. 8600 Rockville Pike Positioned anterior to the ring, the rectus aponeurosis provides a hiatus for the exiting bundle. The management of abdominal wall pain depends on the etiology. The TAP is accessed from the lumbar triangle of Petit, bounded anteriorly by the external oblique, posteriorly by the lattisimus dorsi, and inferiorly by the iliac crest (Fig. These fatty plugs can often be palpated in asymptomatic persons and may normally feel uncomfortable to firm palpation, attesting to the fact that their location predisposes them to trauma. Nerve entrapment after Pfannenstiel incision. In such circumstances, a patient should be encouraged to return to the clinic if the pain recurs or if new symptoms arise. These patients may need further examination, even if ACNES caused the pain that brought them to the doctor. The abdominal wall: an overlooked source of pain. Lying down may help but sometimes worsens the pain. Haemodynamic effects are minimal as spread of local anaesthetic is limited to the abdominal wall. e lateral border of the rectus abdominis muscle. The injection serves two purposes: to relieve pain and to reduce herniation of the neurovascular bundle through the fibrous ring. McGrady EM, Marks RL. See permissionsforcopyrightquestions and/or permission requests. A phone call from the patient after a few days is all that is needed to confirm treatment success. These instructions may seem rudimentary; however, if followed exactly, they will guarantee success in diagnosing and treating ACNES. Younger people, who are usually more physically active than older persons, are more often seen for the first episode of acute pain. Abdominal wall pain easily differentiated from visceral origin. To be sure the needle is positioned precisely (Figure 3)24 at the correct place for injection, the examiner should first place the middle finger of one hand in the aponeurotic opening and then, without lifting the finger off the skin, move the fingertip inferiorly, cleanse the skin with alcohol using the other hand, and with that hand introduce the needle above the tip of the examining finger. A local anesthetic injection can confirm the diagnosis when there is 50% postprocedural pain improvement. Such pain can suggest urolithiasis; however, patients with urolithiasis are usually seen writhing in pain, whereas patients with ACNES tend to lie quietly on the table with their hand placed over the area of discomfort. A history and targeted physical examination, potentially complemented with local anesthetic injection or ultrasonography, generally can promptly and accurately identify the abdominal wall as the source of pain. The rectus abdominis muscle: superficial, anterior and vertical, located on either side of the midline, is contained in an inextensible aponeurotic sheath. Hershfield NB. 1). As mentioned above, landmarks of the pertinent structures can best be felt with the patient standing and bearing down, and the injection can be given in this position. Pain improvement of 50% or more confirms the diagnosis of abdominal wall pain. Identify the rectus abdominis muscle and posterior rectus sheath. Anesth Analg 2008;107: . Other Nerves.
