Introduction Pain management is an integral part of Enhanced Recovery After Surgery (ERAS) following laparoscopic colonic resection. A variety of regional and neuraxial techniques were proposed, but their efficacy is still controversial. This systematic review evaluates published evidence on analgesic techniques and their impact on postoperative analgesia and recovery for laparoscopic colonic surgery patients. Methods We conducted bibliographic research on May 10, 2021, through PubMed, Cochrane database, and Google scholar. We retained meta-analysis and randomized clinical trials. We graded the strength of clinical data and subsequent recommendations according to the Oxford Centre for Evidence-Based Medicine. Results Twelve studies were included. Thoracic epidural analgesia improved postoperative analgesia and bowel function following laparoscopic colectomy. However, it lengthens the hospital stay. Transversus abdominis plane block was as effective as thoracic epidural analgesia concerning pain control but with better postoperative recovery and lower length of hospital stay. Moreover, Lidocaine intravenous infusion improved postoperative pain management and recovery; Quadratus lumborum block provided similar postoperative analgesia and recovery. Finally, wound infiltration reduced postoperative pain without improving recovery of bowel function, and it could be proposed as an alternative to thoracic epidural analgesia. Conclusions Several analgesic techniques have been investigated. We found that abdominal wall blocks were as effective as thoracic epidural analgesia for pain management but with lower hospital stay and better recovery. We registered this review on PROSPERO (ID: CRD42021279228).

Background: For the diagnosis of acute pulmonary embolism, chest computerized tomography (CT) angiography is considered as the gold standard. However, echocardiography could be useful especially in cases of high suspicion with normal CT scan or for patient with hemodynamic instability. Case presentation: We present a case of a 47-year-old man admitted to the intensive care unit with a diagnosis of respiratory failure and hemodynamic instability 24 hours after closed fracture of the right leg. Before his admission, a thoracic CT angiography was done but did not show any sign of acute pulmonary embolism. During the first hours, he presented a bad evolution with a respiratory status which failed to respond to high dose of vasopressor, oxide nitric and ventilatory support. Therefore, due to the poor echocardiographic window, transesophageal echocardiography examination was done in emergency. It revealed high-probability diagnosis of massive pulmonary embolism based on right ventricular dysfunction and the presence of thrombus in the right pulmonary artery. Anticoagulant therapy (non-fractioned heparin) was administrated immediately achieving a favorable clinical outcome with rapid withdrawal of dobutamine, nitric oxide and norepinephrine. Conclusions: This case illustrates the fundamental role of transesophageal echocardiography in a critically ill patient with shock due to high-probability pulmonary embolism. Echocardiography allows the initiation of adequate treatment without further delay.
