Laparoscopic appendectomy as a teaching procedure: experiences with 1,197 patients in a community hospital

PURPOSE

Since laparoscopic procedures have become more common, resident surgeons have to learn complex laparoscopic skills at an early stage of their career. The aim of this study was to compare the short-term clinical outcome parameters of laparoscopic appendectomy (LA) performed by resident surgeons (RS) or attending surgeons (AS).

METHODS

A total of 1197 LA and 57 open appendectomies were performed in a Swiss community hospital between 1999 and 2009. RS performed 684 operations. Parameters including the duration of the operation and hospital stay, intraoperative complications, surgical reinterventions, and a 30-day morbidity and mortality were observed.

RESULTS

The mean age of the patients was 35.6 ± 18.17 years. The duration of the operation was longer (61.34 ± 25.73 min [RS] vs. 53.65 ± 29.89 [AS] min; p = 0.0001), but the hospital stay was shorter, in patients treated by RS (3.92 ± 2.61 days [RS] vs. 4.87 ± 3.23 [AS] days; p = 0.0001). The rate of intraoperative complications was not significantly different between the two groups (1.02 % [RS] vs. 0.8 % [AS]; p = 0.6). The need for surgical reintervention (0.6 % [RS] vs. 2.5 % [AS]; p = 0.005) and the 30-day morbidity were higher in patients treated by AS (3.7 % [AS] vs. 1.8 % [RS]; p = 0.04). There was no postoperative mortality.

CONCLUSIONS

Under appropriate supervision, surgical residents are able to perform LA with results comparable to those of experienced surgeons.

Laparoscopic cholecystectomy as a teaching operation: comparison of outcome between residents and attending surgeons in 1,747 patients

PURPOSE

Standardized surgical training is increasingly confronted with the public demand for high quality of surgical care in modern teaching hospitals. The aim of this study was to compare the results of laparoscopic cholecystectomy (LC) performed by resident surgeons (RS) and attending surgeons (AS).

METHODS

In this retrospective review of prospectively collected data 1,747 LC were performed in a community hospital between 1999 and 2009. Seven hundred seventy operations were performed by RS. Parameters analysed included the duration of operation and length of hospital stay, intraoperative complications, 30-day morbidity and mortality.

RESULTS

Duration of operation was 88 (25-245) min for RS vs. 75 (30-190) min by AS (p = 0.001). Elective operations were shorter when performed by AS (70 (30-190) [AS] vs. 85 (25-240) [RS] min, p = 0.001). Length of hospital stay was shorter in patients treated by RS (4 (1-49) days [RS] vs. 5 (1-83) days [AS], p = 0.1). Intraoperative complications showed no differences between the groups (1.0% [RS] vs. 1.3% [AS], p = 0.6), whereas 30-day morbidity was lower in patients treated by RS (3.8% [RS] vs. 6.2% [AS], p = 0.02). Overall mortality was 0.6% and independent of surgical expertise (0.5% [RS] vs. 0.8% [AS], p = 0.5).

CONCLUSIONS

Provided adequate training, supervision and patient selection, surgical residents are able to perform LC with results comparable to those of experienced surgeons.

A critical analysis of laparoscopic appendectomy: how experience with 1,400 appendectomies allowed innovative treatment to become standard in a university hospital

BACKGROUND

Although advantages of laparoscopic appendectomy (LA) have not yet been proved, there is increasing evidence that LA provides diagnostic and therapeutic advantages as compared to conventional surgery. This article reports the introduction of LA in a university hospital where LA now represents the standard operative procedure in patients with suspected appendicitis.

METHODS

Consecutive patients with appendectomy were prospectively included in the surgical database from 5/1991 to 10/2005. Operating time skin-to-skin in minutes, conversion from laparoscopy to open appendectomy, and complications requiring reoperation as well as surgical expertise were recorded.

RESULTS

After initial performance of LA by four experienced specialists in laparoscopic surgery between 1991 and 1994, LA was routinely implemented from 1995 to 2005. Laparoscopic appendectomy was performed in 1,012 patients, and conventional appendectomy in 449 patients, with a LA rate of about 90% in recent years. Intraoperative conversion was deemed necessary in 62 patients (6.2 %) by 40 surgeons among the 103 surgeons who performed LA over 14 years with a mean operative time of 57 +/- 2 min. Between 1995 and 2005 about 25%-30% of LAs were performed as the first LA for the respective surgeon. Laparoscopic appendectomy was associated overall with a reduced length of stay in the hospital compared to open appendectomy (LA: 4.4 +/- 0.1 days versus 6.6 +/- 0.2 in open appendectomy; p < 0.001).

CONCLUSIONS

This analysis provides evidence that LA can be introduced in an university hospital with acceptable results despite low operation numbers per surgeon and a liberal teaching policy. The LA procedure, which is associated with a 2%-4% rate of reoperation, may serve as laparoscopy training for young surgeons.

[Job stress and quality of life of primary care health-workers: evidence of validity of the PECVEC questionnaire]

OBJECTIVES

To evaluate the relationship between Health-Related Quality of Life (HRQL) and stress at work among Primary Care workers, as evidence of the construct validity of the Spanish version (PECVEC) of the profile of quality of life in the chronically ill (PLC) questionnaire. In addition, to check its other psychometric properties.

DESIGN

Cross-sectional study.

SETTING

Eighteen primary care centres in Health Area IV, Asturias (Oviedo), Spain, sharing similar socio-demographic conditions.

PARTICIPANTS

Two hundred and thirty-three primary care nurses and physicians.

MAIN MEASUREMENTS

HRQL was evaluated by the 6 general dimensions of the Spanish version of the PLC. Stress at work was evaluated by the three scales of the Effort-Reward Imbalance (ERI) questionnaire.

RESULTS

The construct validity of the PECVEC was assessed by testing the inverse associations of QoL dimensions and job stress ones, when the most important confuser variables were monitored. The non-response rate was low (<3%), and no floor effects and only small ceiling effects were observed. Internal consistency analysis and exploratory and confirmatory factor analysis demonstrated high reliability, factorial validity and convergent/divergent validity of the PECVEC.

CONCLUSIONS

The PECVEC demonstrates adequate psychometric properties for evaluating HRQL in healthy subjects.
