Introduction: Sentinel lymph node biopsy (SLNB) is a key procedure in the staging and management of melanoma. Traditionally, it is performed using a dual-mapping technique combining a radioactive isotope (RI) and blue dye (BD). Fluorescence-guided surgery with indocyanine green (ICG) has emerged as an alternative tracer, offering potential advantages in real-time visualization and operative efficiency.

Article Synopsis
  • Bariatric and metabolic surgery (BMS) is an effective option for treating severe obesity, particularly in patients with a BMI of 50 kg/m or higher.
  • A study analyzed 263 patients who underwent BMS, comparing outcomes between primary surgeries and revisional surgeries; the results showed that revisional patients had higher leak rates and longer hospital stays.
  • The mortality rate was low at 1.1% for both groups, but more research is needed to determine the best surgical techniques for patients with extremely high BMI.

Article Synopsis
  • One anastomosis gastric bypass (OAGB) has growing popularity and offers favorable long-term outcomes, with limited data specifically on revisional OAGB (rOAGB).
  • A study analyzed data from 424 patients, revealing that primary OAGB (pOAGB) showed greater mean total weight loss compared to rOAGB, although both groups experienced significant resolution of type 2 diabetes and hypertension.
  • Overall, OAGB is an effective solution for severe obesity, with acceptable rates of surgical revisions and complications, but more extensive research is needed for conclusive insights.
