Chronic pancreatitis is a common cause of recurrent chronic abdominal pain that utilizes significant health care resources. Pain in chronic pancreatitis can be of two types. Visceral pain occurs during ongoing pancreatic inflammation. Once pancreatic inflammation subsides, the pain generator can move to the abdominal wall as a result of viscerosomatic convergence and present as abdominal myofascial pain syndrome. Subcostal transversus abdominis plane block is an abdominal plane block that has been proven effective in upper abdominal pain of somatic origin. ⋯ Subcostal transversus abdominis plane block may be an option in the management of abdominal myofascial pain syndrome secondary to chronic pancreatitis. The block is ineffective in producing clinically significant pain relief in the presence of ongoing pancreatic inflammation.

Comparative StudyWhich Is More Effective for Minimally Invasive Pectus Repair: Epidural or Paravertebral Block?
Objective: The aim of this study was to compare the effectiveness of epidural block (EDB) and paravertebral block (PVB) for minimally invasive pectus repair with the conventional method in terms of pain control during and after pectus operations, patient comfort, and length of stay in hospital. Materials and Methods: A retrospective review was made of patients who underwent minimally invasive pectus repair. The patients were allocated into three groups as follows: PVB group (Pre-emptive ultrasound-guided bilateral thoracic single injection PVB, n = 15); EDB group (Pre-emptive landmark-guided single injection thoracic EDB, n = 8); and Control group (Neither PVB nor EPB, n = 9). ⋯ Although the length of stay in hospital was shorter in the PVB and EDB groups compared to the control group, the difference was not statistically significant (P = .422). Conclusion: Epidural and bilateral paravertebral blockades performed in conjunction with general anesthesia decrease the intraoperative and postoperative need for analgesics, and might be beneficial for pain management and contribute to a shorter length of hospital stay for patients undergoing minimally invasive pectus repair operations. Both blockades also significantly improved the patient satisfaction.

The aims of this study were to investigate the current clinical practice of ultrasound (US)-guided stellate ganglion block (SGB) using a bi-national survey of Korea and Japan, and to clarify the anatomical relation of the cervical sympathetic trunk with the prevertebral fascia at the level of cervical vertebrae. The current clinical practice of US-guided SGB in Korea and Japan was investigated using an Internet survey, which received 206 (10.2%) replies from Korea and 97 (8.8%) replies from Japan. The survey questionnaire addressed the actual clinical practice for US-guided SGB, including where the tip of the injection needle is placed. ⋯ The final position of the needle tip also clearly differed in an US image, being predominantly positioned above the prevertebral fascia in Korea (39.3%) and under the prevertebral fascia in Japan (59.8%). In all of the anatomic dissections, the cervical sympathetic trunk was over the prevertebral fascia at the level of the sixth vertebra and under the prevertebral fascia at the level of the seventh vertebra. These results are expected to improve the knowledge on the current clinical practice and to suggest future studies.

Randomized Controlled Trial
A Randomized Controlled Trial of FNB versus FICB for Patients with Femoral Neck Fractures Before Spinal Anesthesia.
Patients with femoral neck fractures often suffer severe pain. This randomized controlled clinical study compared the effect of femoral nerve block (FNB) and fascia iliaca compartment block (FICB) in this population. ⋯ FNB and FICB produce similar analgesic effects in patients with femoral neck fractures, but FNB has a more rapid onset of pain relief.
