Ultrasound guided percutaneous drainage of abdominal abscesses in the hands of the clinician: a multicenter Italian study

Surgery for Conditions of Infectious Etiology in Resource-Limited Countries Affected by Crisis: The Médecins Sans Frontières Operations Centre Brussels Experience

BACKGROUND

Surgery for infection represents a substantial, although undefined, disease burden in low- and middle-income countries (LMICs). Médecins Sans Frontières-Operations Centre Brussels (MSF-OCB) provides surgical care in LMICs and collects data useful for describing operative epidemiology of surgical need otherwise unmet by national health services. This study aimed to describe the experience of MSF-OCB operations for infections in LMICs. By doing so, the results might aid effective resource allocation and preparation of future humanitarian staff.

METHODS

Procedures performed in operating rooms at facilities run by MSF-OCB from July 2008 through June 2014 were reviewed. Projects providing specialty care only were excluded. Procedures for infection were described and related to demographics and reason for humanitarian response.

RESULTS

A total of 96,239 operations were performed at 27 MSF-OCB sites in 15 countries between 2008 and 2014. Of the 61,177 general operations, 7,762 (13%) were for infections. Operations for skin and soft tissue infections were the most common (64%), followed by intra-abdominal (26%), orthopedic (6%), and tropical infections (3%). The proportion of operations for skin and soft tissue infections was highest during natural disaster missions (p<0.001), intra-abdominal infections during hospital support missions (p<0.001) and orthopedic infections during conflict missions (p<0.001).

CONCLUSION

Surgical infections are common causes for operation in LMICs, particularly during crisis. This study found that infections require greater than expected surgical input given frequent need for serial operations to overcome contextual challenges and those associated with limited resources in other areas (e.g., ward care). Furthermore, these results demonstrate that the pattern of operations for infections is related to nature of the crisis. Incorporating training into humanitarian preparation (e.g., surgical sepsis care, ultrasound-guided drainage procedures) and ensuring adequate resources for the care of surgical infections are necessary components for providing essential surgical care during crisis.

Percutaneous drainage of abdominal and pelvic abscesses in children

It has only been in the last several decades that abscesses within deep compartments, particularly within the abdomen and pelvis, have become safely accessible with imaging guidance. Since that time, percutaneous abscess drainage has become the standard of care in children. We review the clinical features, diagnosis, and image-guided management of abdominal and pelvic abscesses in children.

Goal-directed ultrasound in a limited resource healthcare setting and developing country

Background

In developing countries, access to diagnostic technology is limited by economic, social and geographical barriers. Diagnostic tools must be sustainable, effective and low cost.

Case

A 30-year-old man was admitted in a rural hospital with fever and chest pain and managed successfully with a goal-directed sonographic approach.

Conclusion

Ultrasound is a point of care, rapid, non-invasive and low-cost technology. Primary goal-directed ultrasound can be a high-impact diagnostic tool in scarce resource scenarios.

Diagnosis of infection in sepsis: An evidence-based review

OBJECTIVE

In 2003, critical care and infectious disease experts representing 11 international organizations developed management guidelines for the diagnosis of infection in sepsis that would be of practical use for the bedside clinician, under the auspices of the Surviving Sepsis Campaign, an international effort to increase awareness and improve outcome in severe sepsis.

DESIGN

The process included a modified Delphi method, a consensus conference, several subsequent smaller meetings of subgroups and key individuals, teleconferences, and electronic-based discussion among subgroups and among the entire committee.

METHODS

The modified Delphi methodology used for grading recommendations built on a 2001 publication sponsored by the International Sepsis Forum. We undertook a systematic review of the literature graded along five levels to create recommendation grades from A to E, with A being the highest grade. Pediatric considerations to contrast adult and pediatric management are in the article by Parker et al. on p. S591.

CONCLUSIONS

Obtaining a precise bacteriological diagnosis before starting antibiotic therapy is, when possible, of paramount importance for the success of therapeutic strategy during sepsis. Two to three blood cultures should be performed, preferably from a peripheral vein, without interval between samples to avoid delaying therapy. A quantitative approach is preferred in most cases when possible, in particular for catheter-related infections and ventilator-associated pneumonia. Diagnosing community-acquired pneumonia is complex, and a diagnostic algorithm is proposed. Appropriate samples are indicated during soft tissue and intraabdominal infections, but cultures obtained through the drains are discouraged.

Interventional ultrasound: experience in 426 orthotopic liver transplantations

BACKGROUND

The purpose of this study was to analyze the role of interventional ultrasound in the treatment of nonvascular complications in liver transplant recipients.

METHODS

Between August 1996 and May 2003, we performed 426 OLTs in 394 patients, 287 men (73%) and 107 women (27%), mean age of 50 +/- 9.5 years (range 17 to 68.2). A total of 2556 diagnostic ultrasound examinations were performed, resulting in a mean of 5.9 per patient (range 2 to 21). The interventional maneuvers included: echo-guided biopsies; drainage of abdominal or thoracic effusions; drainage of abdominal, intrahepatic, or splenic collections; positioning of biliary drains; and use of the "rendezvous" technique.

RESULTS

Six hundred seventy-seven echo-guided interventional maneuvers were performed in 394 OTL patients, comprising 417 (61.6%) biopsies and 260 (38.4%) therapeutic maneuvers. Eighty-one ascite drains were positioned (31.1%); in 73 cases, pleural effusions were drained (28.1%). Sixty-seven abdominal or intrahepatic collections were drained (25.8%), of which 36 (53.7%) were due to bilomas or biliary peritonitis, 15 (22.4%) hematomas, 4 (5.9%) hepatic abscesses, 11 (16.4%) infected abdominal collections, and 1 (1.5%) splenic abscess. Thirty-nine cases (15%) of biliary drainage were performed. In 33 cases (7.9%), the parenchymal biopsies were not diagnostic because of an inadequate specimen. The treatment success rate was 96.1%. No complications related to the therapeutic maneuvers were recorded, but there were 5 biopsy-related complications (1.2%).

CONCLUSIONS

Echo-guided interventional maneuvers are safe, produce a high success rate, and represent an important option in the management of OLT patients.

Gastrointestinal complications in the intensive care unit

Pathologic conditions affecting the abdomen are a significant cause of morbidity and mortality in the intensive care unit, but their importance is not widely recognized. This article presents several aspects of abdominal pathology that can occur in intensive care unit patients. This pathology may have a considerable impact on the prognosis and survival of the critically ill patient. The diagnostic contribution of laboratory tests and imaging is discussed. Conditions such as the abdominal compartment syndrome, acute mesenteric ischemia, gastrointestinal bleeding, diarrhea, abdominal sepsis, complications of entereal and parenteral nutrition, and ileus in critically ill patients are also reviewed.
