EAES, SAGES, and ESCP rapid guideline: bowel preparation for minimally invasive colorectal resection.

BACKGROUND: Variation exists in practice pertaining to bowel preparation before minimally invasive colorectal surgery. A survey of EAES members prioritized this topic to be addressed by a clinical practice guideline. OBJECTIVE: The aim of the study was to develop evidence-informed clinical practice recommendations on the use of bowel preparation before minimally invasive colorectal surgery, through evidence synthesis and a structured evidence-to-decision framework by an interdisciplinary panel of stakeholders. METHODS: This is a collaborative project of EAES, SAGES, and ESCP. We updated a previous systematic review and performed a network meta-analysis of interventions. We appraised the certainty of the evidence for each comparison, using the GRADE and CINeMA methods. A panel of general and colorectal surgeons, infectious diseases specialists, an anesthetist, and a patient representative discussed the evidence in the context of benefits and harms, the certainty of the evidence, acceptability, feasibility, equity, cost, and use of resources, moderated by a GIN-certified master guideline developer and chair. We developed the recommendations in a consensus meeting, followed by a modified Delphi survey. RESULTS: The panel suggests either oral antibiotics alone prior to minimally invasive right colon resection or mechanical bowel preparation (MBP) plus oral antibiotics; MBP plus oral antibiotics prior to minimally invasive left colon and sigmoid resection, and prior to minimally invasive right colon resection when there is an intention to perform intracorporeal anastomosis; and MBP plus oral antibiotics plus enema prior to minimally invasive rectal surgery (conditional recommendations); and recommends MBP plus oral antibiotics prior to minimally invasive colorectal surgery, when there is an intention to localize the lesion intraoperatively (strong recommendation). The full guideline with user-friendly decision aids is available in https://app.magicapp.org/#/guideline/LwvKej . CONCLUSION: This guideline provides recommendations on bowel preparation prior to minimally invasive colorectal surgery for different procedures, using highest methodological standards, through a structured framework informed by key stakeholders. Guideline registration number PREPARE-2023CN045.

Blood and fluid management during scoliosis surgery: a single-center retrospective analysis.

AIM: In the present retrospective study in scoliosis surgery, we hypothesized that application of a protocol for blood and fluid management, based on goal-directed fluid therapy, cell salvage and tranexamic acid, could lead to reduced allogeneic red blood cells transfusion. METHODS AND MATERIAL: Thirty-five patients, with American Society of Anesthesiologists physical status I/III, between 14 and 18 years scheduled for elective orthopedic surgery of scoliosis, with a planned intensive care unit admission, were enrolled in a retrospective observational study. Patients were divided in two groups. Patients in no-protocol group (Group noPro, n = 18) received a liberal intraoperative fluid therapy and patients in protocol group (Group Pro, n = 17) received fluid therapy managed according to a stroke volume variation-based protocol. The protocol included fluid therapy according to SVV monitor, permissive hypotension, tranexamic acid infusion, restrictive RBC trigger and use of perioperative cell savage. STATISTICAL ANALYSIS USED: Student's t test (2-tailed), Mann-Whitney test, Chi square test were used for statistical analysis of the data. RESULTS: There were no significant differences between the two groups in demographic data and clinical characteristics. Infused crystalloids (p = .003) and transfused allogeneic red blood cells (p = .015) were lesser in Group Pro compared to Group noPro. On the other hand, diuresis (p < .001) and vasopressors administration (p = .042) were higher in Group Pro than in Group noPro. CONCLUSION: The application of a protocol for blood and fluid management, based on goal-directed fluid therapy, cell salvage and tranexamic acid, was associated with less crystalloid fluid administration, less perioperative RBC transfusions and significantly better diuresis than patients in the no-protocol group in scoliosis surgery.
