Effect of Perioperative Dexamethasone and Different NSAIDs on Anastomotic Leak Risk: A Propensity Score Analysis.

BACKGROUND: Perioperative use of nonsteroidal anti-inflammatory drugs (NSAIDs) is associated with risk of anastomotic leak (AL). However, concomitant use of other drugs could infer a bias in risk assessment. Thus, we aimed to interrogate the risk of AL associated with NSAIDs and steroids used perioperatively. METHODS: This study includes a consecutive series of patients having surgery involving an intestinal anastomosis from Jan 2007 to Dec 2009. Data records included demographic, perioperative, and surgical characteristics; AL rates; and use of NSAIDs and steroids. Risk of leak were estimated using unadjusted and multivariable (propensity score)-adjusted logistic regression models and reported as odds ratios (ORs). RESULTS: A total of 376 patients underwent 428 operations of which 67 (15.7 %) had AL. With no medication receivers as reference, the OR for leak when adjusted for age, sex, and propensity score was 1.07 (p = 0.92) for ketorolac, 1.63 (p = 0.31) for diclofenac and 0.41 (p = 0.19) for dexamethasone. Risk was increased for malignancy (OR 1.88, p = 0.023), use of a vasopressor (OR 2.52, p = 0.007), blood transfusions (OR 1.93, p = 0.026), and regular use of steroids (OR 7.57, p = 0.009). CONCLUSIONS: Other factors than perioperative drugs are crucial for risk of AL. Perioperative dexamethasone was associated with a nonsignificant reduced risk of AL.

[Endoscopic surgery]. / Endoskopisk kirurgi.

Endoscopic surgery of the stomach/gastrointestinal tract was developed in the 1990s in Japan as a minimally invasive method of removing early-stage tumours, using a gastro-/coloscope instead of open or laparoscopic surgery. Its advantages are obvious, in that the patient is spared more major surgery, the hospital saves on resources as well as admission to a ward, and society is spared the costs of days of sickness absence. Endoscopic submucosal dissection is considered the most difficult technique, but it allows for the accurate dissection of large tumours. In 1999, Japanese surgeon Takuji Gotoda and his team were the first to perform these types of dissections of early cancers in the rectum using a diathermic needle and a flexible scope.

Duodenal perforation in an infant with rotavirus gastroenteritis.

We describe for the first time a case of an infant with rotavirus gastroenteritis complicated by a duodenal perforation. Awareness of the perforation risk may prevent severe or lethal outcomes in this common infection among infants and children.

Risk of anastomotic leakage with use of NSAIDs after gastrointestinal surgery.

PURPOSE: Analgesic regimes to avoid opioid-related adverse effects have been recommended in gastrointestinal surgery. Non-steroidal anti-inflammatory drugs (NSAIDs) are an important component of opioid sparing regimes in that these drugs indirectly reduce pain by inhibiting inflammation. Although beneficial for most surgical patients, animal studies and recent clinical studies suggest a harmful effect on new intestinal anastomoses by increasing the rate of leakage. NSAIDs may indirectly disturb anastomotic healing by inhibiting inflammation as an integrated part of the wound healing process in an early, critical phase after surgery. METHODS: A literature review based on a structured search in PubMed of clinical and experimental studies investigating the effects of NSAIDs on anastomotic healing and leakage rates after intestinal surgery, as well as proposed mechanisms and effects studied in animal models. RESULTS: Three recent observational cohort studies (accumulated n = 882) indicate an increased rate of anastomotic leakages (15-21%) associated with cyclooxygenase-2 (COX-2) selective NSAIDs after intestinal surgery compared to the leakage rates in controls or historical cohorts (1-4%). Three prospective studies on related topics contain relevant data on NSAIDs and are compared to these studies. Several experimental animal studies support an increased risk for anastomotic leakage with the use of NSAIDs. CONCLUSION: The reported effects of NSAIDs on anastomotic healing suggest an increased risk for leakage. A better understanding of the complex interactions of NSAID-induced inhibition on anastomotic healing is a prerequisite for the safe use of NSAIDs. Until more data are available, a careful use of NSAIDs may be warranted in gastrointestinal anastomotic surgery.

[Surgical treatment of pilonidal disease]. / Kirurgisk behandling av pilonidal sykdom.

BACKGROUND: Pilonidal disease is relatively common and is most often seen in young men. It presents either as acute abscesses or as chronic secretion of pus from inflamed sinus tracts in the gluteal region. Many different methods are used for surgical treatment and recurrences are common. We present an update for surgical treatment of pilonidal disease. MATERIAL AND METHODS: The article is based on literature identified through a non-systematic search in PubMed and the authors' clinical experience. RESULTS: An acute abscess has to be drained before curative surgery can be considered. Definitive surgery should be planned for continuous, recurrent or secreting pilonidal disease. A recent meta-analysis indicates that removal of an asymmetric skin flap and primary closure of the wound by mobilising skin from the opposite side (Bascom cleft-lift procedure) is associated with fewest recurrences, shortest time to healing and fewest infections. INTERPRETATION: The Bascom procedure should be the preferred surgical treatment for patients with pilonidal disease in a chronic phase.
