Examining the learning curve of laparoscopic fundoplications at an urban community hospital.

BACKGROUND: Laparoscopic fundoplication for gastroesophageal reflux disease is a procedure associated with specific complications, especially in a surgeon's early experience. The learning curve of this procedure was examined at a tertiary community institution. METHODS: A retrospective review of the first 100 cases performed at Royal Columbian Hospital was conducted. Two surgeons performed the majority of cases and routinely assisted each other. Patients were grouped chronologically with the first 50 cases defined as early institutional experience and a surgeon's first 20 cases defined as early personal experience. RESULTS: Operative time was longer in both the early institutional (117.8 versus 91.3 minutes, P < .001) and personal experience (126.8 versus 89.7 minutes, P < .001). The rate of dysphagia requiring intervention was higher during the early institutional (22% versus 4%, P = .017) but not personal experience (19% versus 8%, P = not significant). The conversion rate was 0%, reoperation rate was 1%, mean length of stay was 2.5 +/- 1.4 days, and the readmission rate was 5%; these outcomes were unaffected by the learning curve. CONCLUSIONS: There is a definable learning curve in laparoscopic fundoplication in terms of operative time. However, an acceleration of the personal learning curve in terms of dysphagia was observed with a two-surgeon collaborative approach. With careful patient selection conversion, reoperation, readmission, and complication rates equivalent to experienced centers can be achieved in the community setting early in the personal and institutional experience.

Outcomes of sentinel node biopsy for breast cancer in British Columbia, 1996 to 2001.

BACKGROUND: This study evaluated the outcomes of the first 5 years of sentinel node biopsy (SNB) in British Columbia (BC), Canada, 1996 to 2001. METHODS: There were 547 SNB procedures for breast cancer performed by 29 surgeons at 12 hospitals in BC between October 1996 and July 2001. Identification, accuracy, and false-negative rates were determined and correlated to patient, tumor, and surgical factors with the chi-square test. RESULTS: SNB mapping was performed using blue dye alone (15%), radiopharmaceutical alone (6%), or both (79%). A completion axillary dissection was performed in 93%. A median of 2 (range 1 to 16) sentinel nodes was biopsied. The overall identification rate was 88%, accuracy was 92%, and false-negative rate was 22%. All rates were improved in younger (age <50 years) compared with older women. A positive lymphoscintiscan and the mapping agent used were associated with higher identification rates but not accuracy or false negative rates. Increasing surgeon experience was not significantly associated with improvements in identification or false-negative rates. CONCLUSIONS: The potential of SNB was not fully translated into surgical practice in BC by 2001.
