RESUMO
Purpose: Laparoscopic sleeve gastrectomy (LSG) is one of the most common surgical procedures worldwide for the treatment of morbid obesity. Blake-type drains are widely used in this procedure despite the lack of clear evidence regarding their benefits in the diagnosis and treatment of common postoperative complications such as gastric suture line leak (GSLL) and postoperative bleeding (PB). Materials and Methods: A retrospective descriptive study with prospective case registry was conducted, analyzing all patients who underwent LSG between January 2012 and December 2022 at a high-volume center. Our primary outcome was to evaluate the role of drains for diagnosis and treatment of GSLL and PB in LSG. Our secondary outcome was to determine drain related surgical site infection (DRSSI) rate. Results: A total of 335 LSG were performed in the studied period. In all patients one abdominal drain was placed during surgery. Six GSLL (1.79%) and 5 PB (1.49%) were recorded. Drain placement did not prove to ensure early diagnosis or conservative management of GSLL or PB after LSG. Furthermore, an incidence of DRSSI of 4.1% (14 patients) was found. Conclusion: In our study, no clear diagnostic or therapeutic benefits of the systematic use of drains for GSLL or PB in LSG was found; but drain use did show a considerable rate of DRSSI, which must be taken into consideration prior to considering drain systematic use. While no randomized prospective trials have been performed, the retrospective data does not support drain systematic use.
RESUMO
Unilateral primary aldosteronism (PA) is the most common surgically correctable cause of hypertension. Determination of success after laparoscopic adrenalectomy (LA) is limited by the lack of standardized criteria. We sought to evaluate the surgical recurrence and functional outcomes of LA in patients with Conn's syndrome applying the primary aldosteronism surgical outcome (PASO) Criteria. Descriptive observational analysis of patients treated with LA due to confirmed u nilateral Conn's syndrome between May 2007 and August 2020: Twenty patients were included in the cohort; 16 patients had TLA and other four PLA [58% male, median age 47 (IQR: 44-59.5) years and median follow-up of 64 (IQR: 2-156) ] months. Median tumor size was 1.2 (0.8-1.8) cm. No conversions to open surgery were recorded and the overall morbidity of the series was 1/20. No surgical or biochemical recurrence was observed. Five patients were excluded from the analysis of functional results due to lack of follow-up. According to the PASO criteria, complete, partial, and no success were observed in 8/15, 6/15, and 1/15, respectively. The surgical treatment of the disease is supported by the literature, and we were able to reproduce the results of other series. The use of standardized and reproducible criteria to assess its functional results would be essential for a more complete and integrated evaluation of adrenal surgery.

Análisis descriptivo y observacional de pacientes tratados con AL en contexto de síndrome de Conn unilateral confirmado, entre Mayo-2007 y Agosto-2020.

La mediana de tamaño tumoral fue de 1.2 (0.8-1.8) cm. No se registraron conversiones a cirugía abierta y la morbilidad global de la serie: 1/20. No se observó recurrencia quirúrgica o bioquímica.

Según los criterios PASO, se observó un éxito completo, parcial y ausente en 8/15, 6/15 y 1/15, respectivamente.

El uso estandarizado y reproducible de criterios para valorar sus resultados funcionales sería fundamental para una evaluación más completa e integrada de la cirugía suprarrenal.
