When should surgery be considered in my hospitalized patient with divertculitis?

Severe diffuse abdominal pain, fever, tachycardia, leukocytosis or other signs of sepsis and diffuse peritonitis indicative of free perforation requires emergent surgery. Urgent surgery should be considered when your patient fails to improve (eg, abdominal pain or the inability to tolerate enteral nutrition, bowel obstruction, or infection-related ileus) despite medical therapy or percutaneous drainage. 1,2

Lower threshold for surgical intervention is also needed in transplant patients, patients on chronic corticosteroid therapy, other immunosuppressed patients and those with chronic renal failure or collagen-vascular disease because these patients have a significantly greater risk of recurrent, complicated diverticulitis requiring emergency surgery. Overall, up to 20% of patients with acute diverticulitis undergo surgery during the same hospitalization.2

For patients with recurrent uncomplicated diverticulitis, decision regarding future elective surgery should be individualized. Although older guidelines recommended surgery after 2 attacks of uncomplicated diverticulitis, more recent guidelines place less emphasis on the number of episodes and stress the importance of considering the severity of the attacks, chronic or lingering symptoms, inability to exclude carcinoma, overall medical condition of the patient, risks of surgery, and the impact of diverticulitis on the patient’s lifestyle.1,2

Of interest, a decision analysis model suggests that elective resection after a fourth episode may be as safe as earlier resection.3

Should I be concerned about the umbilical hernia in my patient with cirrhosis and ascites?

Although umbilical hernia in patients with cirrhosis and ascites is common and often “expected” (a rate of 20% during the course of their disease), it can be associated with significant risk of complications such as incarceration, ascites drainage, peritonitis, and spontaneous rupture or evisceration from necrosis of overlying skin.1,2

A 2007 retrospective study involving patients with cirrhosis and umbilical hernia reported a complication rate of 77% and related mortality of 15% among those managed conservatively (mean period of observation ~ 5 years); MELD score could not predict failure of conservative management (median 22 in complicated vs 24 in uncomplicated).3

Because the risk of death with hernia repair in urgent settings is 7x higher than for elective hernia repair in cirrhotic patients, there has been increasing interest in elective repair in patients with well-compensated cirrhosis.3 Interestingly, the reported surgical complication rates among patients with well-compensated cirrhosis appear similar to those in noncirrhotic patients.3 If the patient is expected to undergo liver transplantation in the near future, elective hernia repair can be postponed and managed concomitantly.

Bonus pearl: Did you know that spontaneous umbilical hernia rupture is also known as “Flood syndrome” (should be easy to remember!), first described by Frank B Flood, a surgical resident back in 1961? 4

Why has my hospitalized patient with head and neck cancer developed thrombocytosis few days following surgery?

An acute rise in platelet count is not uncommon among hospitalized patients and may be related to several factors, including “tissue damage” from a surgical procedure, infection, and acute blood loss1.  Postoperative thrombocytosis is thought to be related to increased platelet production as well as redistribution of platelets from the splenic platelet pool to the general circulation1.  Increased levels of megakaryocytic growth factors such as thrombopoietin, and pro-or anti-inflammatory cytokines such as interleukin (IL)-1, 3, 6, or 11 may also stimulate megakaryopoeisis in the setting of inflammation2.

Less well known is that enoxaparin (Lovenox), an anticoagulant commonly used for prevention of thromboembolic events in hospitalized patients, may also cause reactive thrombocytosis, usually within the first 2 weeks of therapy and resolving 2 weeks following its discontinuation3

Although malignancy is also associated with secondary thrombocytosis, given its acute nature in our patient, it is less likely to be playing a role.
