INCISIONAL HERNIOPLASTY TECHNIQUES: ANALYSIS AFTER OPEN BARIATRIC SURGERY.

Arq Bras Cir Dig 2020 20;33(2):e1517. Epub 2020 Nov 20.

Postgraduation Program in Surgical Clinics, Federal University of Paraná, Curitiba, PR, Brazil.

Background: Rives-Stoppa retromuscular technique: A) polypropylene mesh fixed on the posterior rectus sheath; B) rectus abdominal muscle; C) anterior rectus sheath being sutured. The best technique for incisional hernioplasty has not been established yet. One of the difficulties to compare these techniques is heterogeneity in the profile of the patients evaluated.

Aim: To analyze the results of three techniques for incisional hernioplasty after open bariatric surgery.

Method: Patients who underwent incisional hernioplasty were divided into three groups: onlay technique, simple suture and retromuscular technique. Results and quality of life after repair using Carolina's Comfort Scale were evaluated through analysis of medical records, telephone contact and elective appointments.

Results: 363 surgical reports were analyzed and 263 were included: onlay technique (n=89), simple suture (n=100), retromuscular technique (n=74). The epidemiological profile of patients was similar between groups. The onlay technique showed higher seroma rates (28.89%) and used a surgical drain more frequently (55.56%). The simple suture technique required longer hospital stay (2.86 days). The quality of life score was worse for the retromuscular technique (8.43) in relation to the onlay technique (4.7) and the simple suture (2.34), especially because of complaints of chronic pain. There was no difference in short-term recurrence.

Conclusion: The retromuscular technique showed a worse quality of life than the other techniques in a homogeneous group of patients. The three groups showed no difference in terms of short-term hernia recurrence.

EFFECTS OF INTRAPERITONEAL GLUTAMINE IN THE TREATMENT OF EXPERIMENTAL SEPSIS.

Arq Bras Cir Dig 2019 29;32(2):e1431. Epub 2019 Apr 29.

Department of Operative Technique and Experimental Surgery of the Pontifical Catholic University of Paraná, Curitiba, PR, Brazil.

Background: Sepsis is an important public health issue and is associated with high treatment costs and high mortality rates. Glutamine supplementation has proven to be beneficial to the functions of the immune system, acting beneficially in the evolution of patients in severe catabolic states.

Aim: To evaluate the effect of glutamine supplementation via intraperitoneal in rats, induced sepsis, considering the following organs: intestines, liver, kidneys and lungs.

Methods: Male Wistar rats subjected to sepsis by ligature and cecal puncture were divided into two groups: control C (n=6) and glutamine G (n=11), in which were administered dipeptiven 20% at a dose of 2 ml/kg/day (equivalent to 0.4g N(2)-L-alanyl-L-glutamine/kg) intraperitoneally 48 h prior to sepsis induction. After 48 h they were euthanized and intestine, liver, lung and kidney were removed for histological analysis.

Results: Intestinal epithelial desquamation of the control group was more intense compared to the glutamine group (p=0.008). In the kidneys, degenerative tubular epithelial changes were less severe in the animals that received glutamine (p=0.029). Regarding to the liver, glutamine group showed lower levels of cell swelling than the control group (p=0.034). In the lung there were no results with statistical significance.

Conclusion: Prior intraperitoneal supplementation with glutamine in experimental animals is able to reduce the damage to the intestinal mucosa, to the kidneys and liver's histoarchitecture.

Performance of the Bard Scoring System in Bariatric Surgery Patients with Nonalcoholic Fatty Liver Disease.

Obes Surg 2017 02;27(2):394-398

Hopital Santa Casa de Misericórdia de Curitiba, Praça Rui Barbosa, 694 - Centro, Curitiba, PR, 80010-030, Brazil.

Background: Nonalcoholic fatty liver disease incidence is related to the presence of obesity and insulin resistance. A treatment of this disease in patients with morbid obesity is bariatric surgery and its diagnosis is extremely important due to the possible progression to cirrhosis or hepatocellular carcinoma. The development of clinical-laboratorial analysis tools to this disease and its complications is necessary as the gold standard for its diagnosis is an invasive procedure. The objective of the study is to evaluate the use of BARD score in the selection of patients who should undergo liver biopsy during bariatric surgery.

Methods: It was a retrospective analysis of patients with hepatic disease who were biopsied between 2012 and 2013. Their clinical and laboratory data were analyzed by BARD score. The results of those who presented score >2 were compared to the rest.

Results: Two hundred ninety-eight patients with hepatic disease were analyzed and among them 70.27 % had score >2. Of the 76 patients with score <1, 1 was diagnosed with liver fibrosis, determining a negative predictive value of 98.68 % for the test (p < 0.05).

Conclusions: The BARD score is still not ideal for the diagnosis of nonalcoholic fatty liver disease, hepatitis, and fibrosis, but it was proved to be effective in the detection of absence of liver fibrosis in a bariatric population.
