The diagnosis of most inguinal hernias can be made with a focused patient history and physical examination. Routine ultrasounds add little value to the diagnosis and management of clinically evident inguinal hernias and can result in treatment delay. These investigations should therefore not be performed where there is a clearly palpable abdominal wall defect and should instead be limited to use in the evaluation of occult inguinal hernias.

For minimally symptomatic hernias, surgical repair can prevent potential complications of hernia incarceration and strangulation, but the risk of post-operative complications from infection, hernia recurrence, and chronic inguinal pain approaches the overall risks of incarceration. Watchful waiting for asymptomatic or minimally symptomatic inguinal hernias is a safe option for carefully selected patients and does not preclude patients from undergoing elective repair should discomfort worsen.

Ultrasound is an accurate and cost-effective imaging modality for initial evaluation of suspected appendicitis in the pediatric population. Evidence shows that the sensitivity and specificity of ultrasound is high with reports of up to 95%, though this may vary based on center experience and capabilities. Where findings on ultrasound exam are equivocal, CT can be considered as part of a step-up investigative approach after discussion with the patient and caregivers about risks of childhood radiation exposure.

Obtaining routine preoperative radiological and laboratory testing offers little value to the perioperative care of asymptomatic patients undergoing low-risk surgery. Evidence suggests that abnormal results within this setting rarely affect management or change clinical outcomes. Instead, a focused history and physical examination should be performed to identify which preoperative investigations are required. Where preoperative testing may add value is in the setting of symptomatic patients or higher risk surgery where significant blood loss and fluid shifts may be expected. A discussion with the patient, anesthesiologists, and surgical team would help guide decision-making in these circumstances.

The aim of screening investigations for colorectal cancer, such as fecal immunochemical test (FIT) and colonoscopy, is to reduce deaths through early detection and removal of polyps (a precursor to colon cancer) and early stage colorectal cancers. While colonoscopy is a safe screening modality, increased risks have been associated with advanced age and comorbidities. Life expectancy, presence of symptoms, personal and family history, previous investigations, and patient preference must all be considered in order to determine the safety and appropriateness of screening investigations and surveillance colonoscopy. If colonoscopy is determined to be unsafe or inappropriate, FIT should not be offered as an alternative.

CPM for early stage breast cancer lacks evidence for survival benefit in average risk women with unilateral breast cancer. CPM can be associated with chronic pain, poor cosmetic outcome, and doubles the risk of post-operative infection and bleeding. Recommended surgical options for treatment for a unilateral early breast cancer in average risk women include lumpectomy and nodal staging or unilateral mastectomy and nodal staging. CPM is recommended for women with unilateral breast cancer and previous Mantle field radiation or a BRCA 1/2 gene mutation. CPM can also be considered by the surgeon on an individual basis for women with unilateral breast cancer and a genetic mutation in the CHEK2/PTEN/p53/PALB2/CDH1 genes, and in women who may have difficulty achieving symmetry after unilateral mastectomy. In all cases, the rationale, risks, and benefits of CPM should be discussed with patients and carefully considered based on each individual patient’s particular situation.

Opioid use poses considerable health risks to patients including opioid use disorder, overdose, and side-effects such as psychomotor impairment. While opioid analgesia may be appropriate in select circumstances, prolonged use of opioids beyond the immediate postoperative period and for chronic non-cancer pain is not recommended. Instead, clinicians and patients should consider alternative therapies, such as non-opioid pharmacologic therapy or non-pharmacologic therapies. If opioid analgesia is required, the lowest effective dose, potency, and number of doses required to address the acute pain episode should be prescribed.
