Does preoperative enteral or parenteral nutrition reduce postoperative complications in Crohn’s disease patients?

“Surgery is frequently needed in Crohn’s Disease (CD) patients who have malnutrition. Patients with CD are at a risk of malnutrition secondary to decreased oral intake, malabsorption, and inflammation. The prevalence of malnutrition in IBD patients is profound: 60–80% of IBD patients are anemic, 39–81% are iron deficient, 20–60% are vitamin B12
deficient, 36–54% are folate deficient, and 25–80% have hypoalbuminemia. This high prevalence of malnutrition presents a challenge in the surgical management of CD patients because poor preoperative nutritional status has been linked to increase postoperative complications.
Therefore, nutritional optimization using enteral nutrition (EN) and total parenteral nutrition (TPN) have been used for many years to improve the nutritional status of CD patients in hopes of decreasing postoperative complications.”

Venous Thromboembolism Prevention in Emergency General Surgery

“Venous thromboembolism (VTE) represents the most preventable cause of morbidity and mortality in hospitalized patients, and the Agency for Healthcare Research and Quality (AHRQ) suggests appropriate VTE prophylaxis as a top patient safety practice. The burden of operative and nonoperative emergency general surgery (EGS) is increasing and represents 7% of all hospital admissions in the United States. The reported rate of VTE among patients undergoing EGS is approximately 2.5%. Numerous observational studies, quality improvement studies, randomized clinical trials, reviews, and practice management guidelines are available to guide acute care surgeons in VTE prevention for patients with trauma. However, little guidance is available for the emergency general surgeon. Patients undergoing EGS represent a challenge regarding VTE prevention. Despite the substantial number of annual EGS admissions, little is known about the risk of VTE or the use of mechanical and/or pharmacologic prophylaxis in EGS patients. Furthermore, although guidelines for VTE prophylaxis are available, they are difficult to interpret in the context of admission to an EGS service for an acute condition, particularly when admissions to such services include as many as 70% of patients who do not require operative intervention.”

Definition and grading of postoperative pancreatic fistula

“Based on the literature since 2005 investigating the validity and clinical use of the original
International Study Group of Pancreatic Fistula classification, a clinically relevant postoperative pancreatic fistula is now redefined as a drain output of any measurable volume of fluid with an amylase level >3 times the upper limit of institutional normal serum amylase activity, associated with a clinically relevant development/condition related directly to the postoperative pancreatic fistula. Consequently, the former “grade A postoperative pancreatic fistula” is now redefined and called a “biochemical leak,” because it has no clinical importance and is no longer referred to a true pancreatic fistula. Postoperative pancreatic fistula grades B and C are confirmed but defined more strictly. In particular, grade B requires a change in the postoperative management; drains are either left in place >3 weeks or repositioned through endoscopic or percutaneous procedures. Grade C postoperative pancreatic fistula refers to those postoperative pancreatic fistula that require eoperation or lead to single or multiple organ failure and/or mortality attributable to the pancreatic fistula.”

Inter-Rater Agreement of the Classification of Intraoperative Adverse Events (ClassIntra) in Abdominal Surgery

“In surgery, adverse events and medical errors occur pre-operatively, intraoperatively, and postoperatively. Standardized classification of postoperative complications, for example, using the Clavien-Dindo classification, is widely adopted, and has proven relevant to research and quality improvement programs. Prospectively validated classification systems for intraoperative adverse events (iAEs) are not yet broadly adopted. IAEs have a major impact at many levels. First, there is an association between iAEs and postoperative outcome. Second, hospital stays for patients experiencing iAEs are 40% more expensive compared with patients without iAEs. Third, readmission rates in patients whose surgery is
complicated by an iAE are twofold higher. Recently a promising new and practical classification system for iAEs was proposed, the classification of intraoperative complications (CLASSIC). CLASSIC defines iAEs as any deviation from the ideal intraoperative course occurring between skin incision and skin closure, irrespective of the origin (ie, surgical and anesthesiological difficulties, or technical failures). Compared with previous scores such as the severity score by Kaafarani et al. ClassIntra is more inclusive,
accounting for any type iAE, for example, surgical, anesthesiologic, and organizational, and can be graded directly after skin closure.”

Surgical technique in constructing the jejunojejunostomy and the riskof small bowel obstruction after Roux-en-Y gastric bypass

“Laparoscopic Roux-en-Y gastric bypass (RYGB) surgery is an effective bariatric procedure with excellent outcomes in terms of weight loss and reducing co-morbidities. Large series have demonstrated that the procedure can be performed with low postoperative morbidity and very low mortality. However, concerns have been raised about long-term complications, especially small bowel obstruction (SBO).
In Sweden, RYGB is almost exclusively performed laparoscopically using the antecolic, antegastric Gothenburg technique. Since the technique was first described, alterations have been introduced to reduce the risk of internal herniation, but these modifications have been reported to increase the risk of kinking of the jejunojejunostomy (JJ). Our group has previously demonstrated that diagnostic laparoscopy in RYGB patients suffering from postprandial symptoms often reveals surgically correctable dysfunction/kinking at the JJ.”

Institution of a Preoperative Stoma Education Group Class Decreases Rate of Peristomal Complications

“Over the previous 2 decades, a greater emphasis has been placed on preoperative education for patients anticipated to require a new stoma as part of an upcoming surgery. Preoperative stoma site marking, in combination with education and counseling with an ostomy nurse prior to surgery, has been associated with a decrease in stomal and peristomal complications such as peristomal skin irritation and appliance leakage.”

Preoperative inspiratory muscle training for postoperative pulmonary complications in adults undergoing cardiac and major abdominal surgery

Posted on by
Reply

“Despite advances in perioperative care in the last few decades, postoperative pulmonary complications (PPCs) are probably the leading cause of morbidity and mortality in adults undergoing chest and abdominal surgery. PPCs and cardiac complications are commonly regarded as the two major causes of perioperative problems in selected groups of patients undergoing these high-risk surgical procedures. However, PPCs are more common than postoperative cardiac complications and play a bigger role in mortality and healthcare costs. Despite these factors, the natural history of PPCs and the necessity of preventive strategies have not been well recognized in studies to date.”
