Edema in the subcutaneous soft tissue of the lumbar spine is a frequent incidental finding in spinal magnetic resonance imaging, however, its exact explanation is yet to be determined. The aim of this paper is to provide a systematic literature review on posterior lumbar subcutaneous edema (LSE). The present systematic literature search was carried out in October 2023 using electronic databases: PubMed, Cochrane library, and Scopus. The current evidence suggests that lumbar edema is correlated with clinical data such as weight and age, and potentially female sex. Moreover, LSE is related to several specific conditions, including both systemic and spinal disorders, such as heart or kidney disorders, as well as low back pain and degenerative and/or inflammatory diseases. It is important to be aware that there is an association between LSE and a variety systemic and spinal disorders. [ABSTRACT FROM AUTHOR]

One Anastomosis Gastric Bypass has been increasingly performed in the setting of bariatric surgery. The addition of gastric pouch banding (BOAGB) may reduce weight regain in the long term. BOAGB may rarely be complicated by MiniMizer ring-related affections. This article reports for the first time a case of bowel obstruction due to internal hernia (IH) through the ring itself, occurring 15 months after BOAGB. A 55 years-old woman presented with unspecific symptoms of sub-acute bowel obstruction 15 months after BOAGB. Work-up revealed IH through the MiniMizer ring and its erosion into the liver. Successful management included laparoscopic ring removal and adhesion-lysis. Postoperative course was uneventful. IH through MiniMizer ring is a rare complication of BOAGB and awareness of this possibility may help diagnosis and prevention. Diagnosis requires high index of suspicion and per-oral contrast CT. Successful management entails laparoscopic device removal. Prevention includes non re-absorbable suture fixation and adequate gastric pouch encirclement. [ABSTRACT FROM AUTHOR]
