Lactate Can Be a Marker of Metabolic Syndrome in Severe Obesity?

Background: Morbid obesity surgery and related complications have increased with time. Aim: To evaluate the relationship between perioperative complications before discharge and preoperative body mass index and obesity surgery mortality score in laparoscopic sleeve gastrectomy. Method: 1617 patients who met the inclusion criteria were evaluated retrospectively. The patients were examined in terms of demographic data, presence of comorbidities, whether there were complications or not, type of complications and obesity surgery mortality score. Results: Complications were seen in 40 patients (2.5%) and mortality wasn’t seen in the early postoperative period before discharge. The mean age of patients with complications was 36.3±10.02 years (19-57) and without complications 34.12±9.54 (15-64) years. The preoperative mean BMI values of patients with and without complications were 45.05±3.93 (40-57) kg/m2 and 44.8±3.49 (35-67) kg/m2 respectively. According to BMI groups 40-45 kg/m2, 45-50 kg/m2 and 50 and over, there was not any statistical significance seen in three groups in terms of complication positivity and major-minor complication rates. There was not any statistical significance seen between the patients with and without major-minor complications and obesity surgery mortality score. Conclusion: There was not any relation between perioperative laparoscopic sleeve gastrectomy complication rates before discharge and BMI and obesity surgery mortality scores.

Is Body Mass Index and Obesity Surgery Mortality Score Important in Perioperative Complications of Laparoscopic Sleeve Gastrectomy Before Discharge?

“…Another problem related to prolonged preoperative fasting is increased insulin resistance, which enhances the metabolic response to surgical trauma. This result is commonly observed on the first and the second day after surgery, and it is directly proportional to the operation complexity 13 .…”

“…O besity is a hard-treatment chronic disease that has become a global epidemic that causes health issues for individuals and society. Although there is evidence of metabolically healthy obesity 13 , there is consensus about its harms, especially about the cardiovascular risks present in obese individuals with fat deposition in the visceral region, as shown in some longitudinal studies 13 .…”

Rational: The metabolic response to surgical trauma is enhanced by prolonged preoperative fasting, contributing to increased insulin resistance. This manifestation is more intense on the 1st and 2nd postoperative days and is directly proportional to the size of the operation. Aim: To compare whether preoperative fasting abbreviation and early postoperative refeeding associated with intraoperative and postoperative fluid restriction interfere in the evolution of patients undergoing gastrojejunal bypass. Methods: Eighty patients indicated for Roux-en-Y gastrojejunal bypass were selected. They were randomly divided into two groups: Ringer Lactate (RL) group, who underwent a 6 hours solids fasting, with the administration of 50 g of maltodextrin in 100 ml of mineral water 2 hours before the beginning of anesthesia; and Physiologic Solution (PS) group, who underwent a 12 hours solids and liquids fasting. Anesthesia was standardized for both groups. During the surgical procedure, 1500 ml of ringer lactate solution was administered in the RL and 2500 ml of physiological solution (0.9% sodium chloride) in the PS. In both groups, the occurrence of bronchoaspiration was analyzed during intubation, and the residual gastric volume was measured after opening the abdominal cavity. In the postoperative period in Group RL, patients started a liquid diet 24 hours after the end of the operative procedure; whilst for PS group, fasting was maintained for the first 24 hours, it was prescripted 2000 ml of physiological solution and a restricted liquid diet after 36 hours. Each patient underwent CPK, insulin, sodium, potassium, urea, creatinine, PaCO2, pH and bicarbonate dosage in the immediate postoperative period, and 48 hours later, the exams were repeated. Results: There were no episodes of bronchoaspiration and gastrojejunal fistulas in either group. In the analysis of the residual gastric volume of the PS and RL groups, the mean volumes were respectively 16.5 and 8.8, which shows statistical significance between the groups. In laboratory tests, there was no difference between groups in sodium; PS group showed a higher level of serum potassium (p=0.029); whilst RL group showed a higher urea and creatinine values; CPK values were even for both; PS group demonstrated a higher insulin level; pH was higher in PS group; sodium bicarbonate showed a significant difference at all times; PaCO2 values in RL group was higher than in PS. In the analysis of the incidence of nausea and flatus, no statistical significance was observed between the groups. Conclusions: The abbreviation of preoperative fasting and early postoperative refeeding of Roux-en-Y gastrojejunal bypass with the application of ERAS or ACERTO Project accelerated the patient’s recovery, reducing residual gastric volume and insulin level, and do not predispose to complications.

“…Existem vários escores clínicos baseados principalmente em marcadores bioquímicos que podem ser usados para avaliar o status do fígado em pacientes com obesidade severa 7 . O índice de esteatose hepática (HSI) é uma ferramenta de triagem para o diagnóstico de esteatose 15 .…”

RESUMO - RACIONAL: A doença hepática gordurosa não-alcoólica já é considerada um problema de saúde pública, principalmente em pacientes com obesidade severa. OBJETIVOS: O objetivo do presente estudo foi investigar os diferentes escores de bioquímiosa disponíveis e determinar qual deles poderia servir melhor como uma ferramenta de avaliação da NAFLD em uma população de obesos. MÉTODOS: Este é um estudo transversal de pacientes obesos. Todos os pacientes foram avaliados com parâmetros laboratoriais séricos 1 semana antes da biópsia e todos os pacientes foram submetidos a biópsia hepática intra-operatória, durante a cirurgia bariátrica. RESULTADOS: Cento e quarenta e três pacientes obesos foram incluídos. Apenas APRI (0,65; IC 95%: 0,55 a 0,8) e HOMA-IR (0,7; IC 95%: 0,58 a 0,82) mostraram capacidade significativa de predição de esteatose grave. HSI, NALFDS, ALS / AST e FIB-4 não foram capazes de prever corretamente esteatose grave na biópsia hepática. APRI mostrou alta especificidade (82%) e baixa sensibilidade (54%). Em contraste, o HOMA-IR apresentou alta sensibilidade (84%) e baixa especificidade (48%). CONCLUSÃO: O NALFDS, FIB-4, AST / ALT e HSI não têm utilidade para avaliação de esteatose grave em pacientes com obesidade severa. Diabetes e avaliação bioquímica relacionada à resistência à insulina, como o HOMA-IR, podem ser empregados como boas ferramentas de rastreamento para esteatose grave em tais pacientes. O escore APRI é a ferramenta diagnóstica bioquímica mais específica para esteatose em pacientes com obesidade severa e pode ser empregado, por equipes médicas, para auxiliar na indicação de cirurgia bariátrica ou metabólica.
