Bilateral interconnected latissimus dorsi-gluteus maximus muscular cutaneous flaps for closure of subfascial infections in lumbar spinal surgery. A technical note.

STUDY DESIGN: A surgical technique for primary closure of postoperative subfascial infections is described. OBJECTIVES: To describe the methods and indications for the use of the interconnected latissimus dorsi-gluteus maximus flap. SUMMARY OF BACKGROUND DATA: Closure of subfascial postoperative infection can be complicated by soft tissue defects and retained implants. Healing by secondary intention is expensive and gives unpredictable coverage of retained hardware. METHODS: A bilateral interconnected latissimus dorsi-gluteus maximus flap was used to cover resultant soft tissue defects according to techniques previously described for the delayed primary closure of myelomeningocele defects. RESULTS: Stable, durable, drainage-free soft tissue coverage was obtained in all patients treated with this technique. CONCLUSION: The latissimus dorsi-gluteus maximus flap represents an effective, economical option for the treatment of patients with subfascial infection after instrumented spinal fusion surgery.

Use of sonography in diagnosing acute appendicitis: comparison of a teaching hospital and a community hospital.

RATIONALE AND OBJECTIVES: We examined patterns of use of sonography in the workup of appendicitis at two hospitals: a 715-bed university-affiliated teaching hospital and a 240-bed nonteaching hospital. In light of increasing concern over the use of health care dollars, we wanted to determine whether the use of sonography in the workup of appendicitis would be more frequent at a teaching than at a nonteaching hospital. METHODS: We examined all cases of appendicitis seen in the emergency room of the teaching hospital in 1993 and all cases of appendicitis seen in the emergency room of the nonteaching hospital in 1992-1993. Exclusionary criteria included pregnancy, altered mental status, or multiple discharge diagnoses. The diagnosis of appendicitis was verified by pathology reports. RESULTS: At the teaching hospital, the use of sonography was 38.5% (65 of 169); at the nonteaching hospital, sonography usage was 39.4% (61 of 155). CONCLUSION: There appears to be no significant difference between teaching and nonteaching hospitals in the frequency of use of sonography in diagnosing patients with appendicitis.

Incidence of deep vein thrombosis after arthroscopic knee surgery: a prospective study.

Deep vein thrombosis (DVT) with subsequent pulmonary emboli (PE) is the most life-threatening complication of knee arthroscopy. Although the incidence of clinically diagnosed DVT after arthroscopy is low, clinical examination is less sensitive and specific than other diagnostic modalities for the detection of venous clot. This study used compression ultrasound to prospectively evaluate patients before and after arthroscopic surgery for the presence of DVT. Preoperatively, patients were screened for DVT risk factors. Eighty-five patients completed the study. Three asymptomatic "silent" DVTs were identified, for an incidence of 3.5%. There was no statistically significant difference between those with and without risk factors for the development of DVT.

Myxedema megacolon.

The radiological findings on barium enema examination of 239 patients with thyroid deficiency (192 hypothyroid and 47 myxedematous) were reviewed. A new radiologic finding of transverse ridging superimposed on megacolon is described in myxedema and an explanation for this finding is postulated. The colonic findings associated with thyroid deficiency are presented.

Aphthoid ulcerations in gastric candidiasis.

Tiny aphthoid erosions appear to represent the earliest detectable radiographic change in gastric candidiasis. In this report, the radiographic appearance of these lesions is correlated with gross and microscopic pathologic anatomy, and the progression of these ulcerations to deeper linear furrows is illustrated. It is hoped that the detection of the gastric candidiasis at this early stage will hasten therapy, and thus decrease the risk of fulminant infection in the immunocompromised host.
