“Surgical resection remains one of the major curative treatment options available to patients
with colorectal liver metastases. Surgery and chemotherapy form the backbone of the
treatment in patients with colorectal liver metastases. With more effective chemotherapy
regimens being available, the optimal timing and sequencing of treatments are important. A
multidisciplinary approach with the involvement of medical oncologists and surgical
oncologists from the beginning is crucial.”
“Colorectal cancer (CRC) represents a major worldwide health care burden, as the
second most common cancer diagnosed in women and third most common in men,
and accounting for 10% of all annually diagnosed cancers and cancer-related deaths
worldwide.
As result of improvements in detection through screening, better referral
pathways, centralisation of services, effective primary surgery, development of
systemic chemotherapy, biological agents, and understanding of tumour biology,
survival rates following diagnosis have improved.
Nevertheless, at least 25%-50% of patients with CRC develop colorectal liver
metastases (CRLM) during the course of their illness.”
“Advances in surgical techniques and perioperative management over the last 2–3 decades have enabled the safe performance of hepatic resections. In the 1980s, when the perioperative mortality was reported to be as high as around 10%, drain placement was
considered to be necessary so as to provide information about intraabdominal adverse events promptly and for prophylactic drainage. However, as the necessity of drain placement in other surgical fields has been ruled out and as the incidence of life-threatening adverse
events after hepatic resection decreased, several randomized controlled trials (RCTs) were performed; the conclusions of these trials were that drain placement was not necessary. However, some of them lacked a primary endpoint and calculation of sample size; in
the other studies, the primary endpoint was the incidence of wound-related complication, most of which could be resolved using antibiotics or bed-side opening of the wound, corresponding to Clavien-Dindo (C-D) grade 11 2 or even 1.”
“Historically, prophylactic intraoperative peritoneal drain placement has been advocated after hepatectomy in order to identify and drain bile leaks and decrease the risk of potential perihepatic fluid collections and abscess formation postoperatively. Several small randomized trials have suggested, however, that routine abdominal drainage after elective liver resection may not be necessary.”
“The use of drains in surgery has been practiced for many years. Prophylactic drainage of the abdominal cavity is employed to prevent the formation of collections and abscesses and for early detection of complications. For years, there has been debate as to whether the use of prophylactic drains has more advantages than disadvantages. For many procedures such as routine colon resection, cholecystectomy, and appendectomy, the use of prophylactic drains has been abandoned as studies have shown that drains do not lower the rate of postoperative complications. However, there is still debate of whether to leave a drain routinely after major liver resection.”
“Atrial fibrillation, the most common sustained dysrhythmia, is a common postoperative complication. Previous studies have shown that the incidence, prevalence, and associated morbidity and mortality increase progressively with age.
Development of POAF and mortality is dependent upon a wide range of factors not limited to age and medical comorbidities. Although a patient may be at an increased risk for POAF this does not mean they are at an increased risk for mortality.”
One discussion this week involved etiologies of postpancreatectomy hemorrhage.

Summary: With the purpose of creating algorithms for managing postpancreatectomy hemorrhage (PPH), Yekebas et al (2007) restrospectively analyzed more than 1669 pancreatic resections conducted between 1992 and 2006. They concluded that the prognosis of postpancreatectomy hemorrhage (PPH) is primarily dependent on the presence of “preceding pancreatic fistula” (p.269).
