Evaluation of Surgical Line Reinforcement procedure Effect on the Complications of Laparoscopic Sleeve Gastrectomy: Analysis of the Latest Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) data, 2015.

Seyed Mohammad Kalantar Motamedi, MD, MPH1, Rami R Mustafa, MD1, Gwen Bonner, MD1, Amir Kasaeian, PhD2, Mujjahid Abbas, MD1, Tomasz Rogula, MD1, Leena Khaitan, MD, MPH1. 1University Hospitals of Cleveland, Case Western Reserve University, Cleveland, Ohio, USA, 2Hematology-Oncology and Stem Cell Transplantation Research Center, Tehran University of Medical Sciences, Tehran, Iran.

Introduction: There has been debates on the effectiveness of staple line reinforcement (SLR) in prevention of leaks in bariatric surgeries specifically Laparoscopic Gastric Sleeve (LGS). The earlier analysis of national data from Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) 2010-2014 was showing that at patient level, the SLR is increasing the rate of the leaks.(1) However it decreased the bleeding rate.

Method: We used the most recent national data from MBSAQIP 2015(2). Univariate analysis and adjusted hierarchical logistic regression model were implemented to evaluate association of leaks with patient related factors as well as operation related measures. Patients with any missing data were excluded from the model.

Results: Out of 168093 patients in MBSAQIP 2015 data 98292 (58.5%) had LSG. Data was available for 58876 (59.9%) cases of which 39504 (67.1%) had received SLR. In adjusted model, leaks were only associated with factors (Odds ratio, P-value) such as anticoagulation therapy (5.89, 0.003), history of previous surgery (1.95, 0.24) and bleeding (1.99, <.001). Each 10 minutes increase in operation length was associated with 5% increase in leak (P-value = <.001).

 Also bleeding was only associated with anticoagulation therapy (4.5, <.001), staple line check with provocative test (0.63, .001), drain placement (1.4, .008), hyperlipidemia (1.6, <.001) and history of GERD (1.4, .008).

Each 10 minutes increase in operation length was associated with 3% increase in probability of bleeding (P-value = 0.02).

SLR was not associated with leaks (p-value=0.75) or bleeding (P-value=0.4) in adjusted model.

Conclusion: We found no evidence that SLR procedure might either decrease or increase the incidence of major complications such as bleeding or leaks in laparoscopic sleeve gastrectomy. This finding differs from the previous MBSAQIP results for leaks. Provocative leak test is protective against bleeding by 37%. Operative time was associated with increased risk for both leaking and bleeding.

Respuesta de SAGES al Estudio NordICC sobre el beneficio de las colonoscopias de detección

SAGES desea aclarar los resultados del estudio NordICC y colocarlos en contexto de los esfuerzos de varias agencias nacionales para reducir el riesgo de cáncer colorrectal – la segunda causa de muerte por cáncer más frecuente en los Estados Unidos-, mediante la promoción de la detección y tratamiento oportuno de las lesiones.

SAGES Response to NordICC Study Regarding Benefit of Screening Colonoscopies

The NordICC Study recently published in The New England Journal of Medicine and widely reported on by media outlets has raised questions regarding the benefit of screening colonoscopy in lowering the risk of colorectal cancer and cancer-related deaths among otherwise healthy and symptom-free men and women aged 55 to 64. Provocative headlines and commentaries have […]
