Abdominal pain in patients with inflammatory bowel disease in remission: A prospective study on contributing factors.

BACKGROUND: Abdominal pain is highly prevalent in patients with inflammatory bowel disease (IBD) in remission, but the aetiology is incompletely understood. AIM: To investigate the association of clinical, lifestyle and psychosocial factors with abdominal pain in patients with IBD in remission. METHODS: We performed a prospective multicentre study enrolling consecutive patients with IBD. Data were collected between 1 January 2020 and 1 July 2021, using myIBDcoach, an established remote monitoring platform for IBD. Chronic abdominal pain in IBD in remission (IBDremissionPain+) was defined as abdominal pain score ≥3 (0-10 NRS) on ≥1/3 of all assessments, combined with faecal calprotectin <150 µg/g in 90 days around periodic assessments. Disease activity, lifestyle and psychosocial factors were assessed every 1-3 months during 18 months. Using linear mixed models, the association of these factors with abdominal pain over time was analysed. RESULTS: We included 559 patients, of whom 429 (76.7%) remained in biochemical remission. Of these, 198 (46.2%) fulfilled the criteria for chronic abdominal pain. IBDremissionPain+ patients were characterised by female sex, younger age, higher BMI, and shorter disease duration. They reported more often or higher levels of stress, fatigue, depressive and anxiety symptoms, and life events (all p < 0.001). In the multivariable analysis, sex, disease entity, fatigue, depressive symptoms and life events were associated with abdominal pain over time (all p < 0.05). CONCLUSION: In this cohort of patients with IBD in remission, abdominal pain was common and associated with psychosocial factors. A more holistic treatment approach for patients with IBD suffering from abdominal pain may improve quality of care and subjective wellbeing.

Combined transverse thoracis plane and pectoral nerve blocks for breast surgery under sedation.

The pectoral nerves 2 (pecs 2) block is widely used as adjunct to general anaesthesia for breast surgery. There are a few case reports and a single case series that describe regional anaesthesia as a single technique or supplemented by light to moderate sedation. Here we describe the management of a 91-year-old ASA physical status 4 patient who presented with a T4 breast malignancy. She was considered unfit for general anaesthesia due to significant valvular heart disease. A wide local excision was successfully performed under a pecs 2 block and a transverse thoracis plane block, supplemented with light sedation. We consider this technique to be a good option for selected patients who are considered unfit for general anaesthesia.

Continuous erector spinae plane block versus thoracic epidural analgesia in video-assisted thoracic surgery: a study protocol for a prospective randomized open label non-inferiority trial.

BACKGROUND: Thoracic epidural analgesia is considered the gold standard for pain relief in video-assisted thoracoscopic surgery. This neuraxial technique blocks pain sensation by injecting a local anesthetic agent in the epidural space near the spinal cord to block spinal nerve roots. Recently, the erector spinae plane block has been introduced as a practical alternative to the thoracic epidural. This interfascial regional anesthesia technique interrupts pain sensation by injecting a local anesthetic agent in between the muscular layers of the thoracic wall. Several case series and three RCTs described it as an effective pain management technique in video-assisted thoracoscopic surgery (Scimia et al., Reg Anesth Pain Med 42:537, 2017; Adhikary et al., Indian J Anaesth 62:75-8, 2018; Kim, A randomized controlled trial comparing continuous erector spinae plane block with thoracic epidural analgesia for postoperative pain management in video-assisted thoracic surgery, n.d.; Yao et al., J Clin Anesth 63:109783, 2020; Ciftci et al., J Cardiothorac Vasc Anesth 34:444-9, 2020). The objective of this study is to test the hypothesis that a continuous erector spinae plane block incorporated into an opioid-based systemic multimodal analgesia regimen is non-inferior in terms of the quality of postoperative recovery compared to continuous thoracic epidural local anesthetic-opioid analgesia in patients undergoing elective unilateral video-assisted thoracoscopic surgery. METHODS: This is a prospective randomized open label non-inferiority trial. A total of 90 adult patients undergoing video-assisted thoracoscopic surgery will be randomized 1:1 to receive pain treatment with either (1) continuous erector spinae plane block plus intravenous patient-controlled analgesia with piritramide (study group) or (2) continuous thoracic epidural analgesia with a local anesthetic-opioid infusate (control group). All patients will receive additional systemic multimodal analgesia with paracetamol and non-steroidal anti-inflammatory drugs. The primary endpoint is the quality of recovery as measured by the Quality of Recovery-15 score. Secondary endpoints are postoperative pain as Numerical Rating Score scores, length of hospital stay, failure of analgesic technique, postoperative morphine-equivalent consumption, itching, nausea and vomiting, total operative time, complications related to surgery, perioperative hypotension, complications related to pain treatment, duration of bladder catheterization, and time of first assisted mobilization > 20 m and of mobilization to sitting in a chair. DISCUSSION: This randomized controlled trial aims to confirm whether continuous erector spinae plane block plus patient-controlled opioid analgesia can equal the analgesic effect of a thoracic epidural local anesthetic-opioid infusion in patients undergoing video-assisted thoracoscopic surgery.
