The American Society of Colon and Rectal Surgeons Clinical Practice Guidelines for Ostomy Surgery

“Statistics regarding ostomy-related metrics remain elusive in the United States because of underreporting and coding limitations. The estimated number of ostomates in the United States is 750,000 to 1 million, with approximately 150,000 new ostomies created each year. Stoma creation has a relatively high rate of associated morbidity, ranging from 20% to 80%; peristomal skin complications and parastomal hernia (PSH) are the most common associated morbidities. A population-based study using the Michigan Surgical Quality Collaborative, which included 4250 patients, identified a 37% unadjusted surgical complication rate for elective cases involving an ostomy and 55% unadjusted surgical complication rate for emergency cases involving an ostomy. In this study, risk-adjusted stoma-related morbidity rates varied significantly among hospitals, indicating a potential to improve outcomes in outlying institutions.”

Survival, Healthcare Utilization, and End-of-life Care among Older Adults with Malignancy-associated Bowel Obstruction

“Among patients with cancer, the estimated prevalence of malignancy-associated bowel
obstruction (MBO) is 3-15%, including up to 51% in ovarian cancer and up to 28% in
cancers of the gastrointestinal tract. MBO is among the most common palliative
indications for surgical consultation5 and typically signifies a poor prognosis, with mean
survival of 3-8 months in surgical cases and 4-5 weeks in those with inoperable MBO.
Managing the considerable symptom burden associated with MBO frequently
requires hospitalization and contributes to high-intensity healthcare utilization.1, In light
of national efforts to address the poor quality and high cost of care near the end of life, it is
critical to understand the relationship between treatment for complications of terminal
cancer, such as MBO, and end-of-life (EOL) care.”

Definitive surgical treatment of enterocutaneous fistula

“Enterocutaneous Fistula (ECF) is defined as an abnormal connection between the gastrointestinal tract and the skin, and it requires labor-intensive medical management and surgical expertise. Complex wound management, severe malnutrition, frequent infectious complications, chronic pain, and depression require significant investment of health care resources and make the short-term and longterm care of these patients difficult. The
subsequent operative management often requires lengthy procedures in hostile abdomens with abundant adhesions and surrounding inflammation. In addition to the significant risk of mortality, morbidity can be equally as devastating.”

Differential diagnosis in inflammatory bowel disease colitis

“Distinction between Crohn’s disease of the colon-rectum and ulcerative colitis or inflammatory bowel disease (IBD) type unclassified can be of pivotal importance for a tailored clinical management, as each entity often involves specific therapeutic strategies and prognosis. Nonetheless, no gold standard is available and the uncertainty of diagnosis may frequently lead to misclassification or repeated examinations. Hence, we have performed a literature search to address the problem of differential diagnosis in IBD colitis, revised current and emerging diagnostic tools and refined disease classification strategies. Nowadays, the differential diagnosis is an untangled issue, and the proper diagnosis
cannot be reached in up to 10% of patients presenting with IBD colitis.”

“The sixth edition of the Japanese Gastric Cancer Treatment Guidelines was completed in July 2021, incorporating new evidence that emerged after publication of the previous edition. It consists of a text-based “Treatments” part and a “Clinical Questions” part including recommendations and explanations for clinical questions. The treatments parts include a comprehensive description regarding surgery, endoscopic resection and chemotherapy for gastric cancer. The clinical question part is based on the literature search and evaluation by an independent systematic review team.”

Posthepatectomy liver failure: A definition and grading by the International Study Group of Liver Surgery (ISGLS)

“Liver resection is used increasingly for the management of a variety of benign and malignant conditions. These data have paralleled substantial advances in perioperative management and operative techniques that have improved the safety of, and extended the indications for, liver resection over the past 2 decades. Extended liver resections, liver resections in diseased liver or liver parenchyma affected by chemotherapy, and repeat
or staged liver resections are being used to achieve curative resection and extend long-term survival. The resulting small functional remnant liver volumes and compromised liver function in these patients increase the risk for the development of posthepatectomy liver failure (PHLF). Despite the introduction of functional and imaging measures to assess preoperatively the size and function of the future liver remnant, as well as the use of
portal vein embolization as a preventive intervention, PHLF remains a major concern and has been shown to be a predominant cause of hepatectomy-related mortality.”

Implications of leukocytosis following distal pancreatectomy splenectomy (DPS) and association with postoperative complications

Posted on by

“Distal pancreatectomy with splenectomy (DPS) is performed to remove pathology of the body and/or tail of the pancreas. The spleen and the left side of the pancreas share blood supply, and often tumor involvement, thus splenectomy is often performed along with distal
pancreatectomy. DPS is an operation that carries a greater than 30% risk of postoperative complications, including infection, postoperative pancreatic fistula (POPF), intraabdominal abscesses, and pneumonia, among others. In addition to these immediate postoperative
complications, splenectomy itself is known to confer long‐term susceptibility to infection, sepsis, thrombosis, and other sequelae. Our goal was to identify factors that could prompt early investigation and treatment of both infectious and major complications.”
