The impact of a laparoscopic colorectal surgeon on the laparoscopic colectomy experience of a single academic center

Learning curves in laparoscopic right-sided colon cancer surgery: a comparison of first-generation colorectal surgeon to advance laparoscopically trained surgeon

BACKGROUND

We aimed to evaluate the learning curve (LC) for laparoscopic right-sided colon cancer surgery (LRCCS) by comparing the results between two surgeons (first-generation colorectal surgeon versus laparoscopically trained surgeon).

METHODS

The study was a retrospective analysis that evaluated 117 consecutive LRCCSs performed by two surgeons, the first-generation surgeon (Surgeon A) and laparoscopically trained surgeon (Surgeon B), from April 1995 to August 2006. Patients were divided into two groups; patients included in groups I and II received LRCCSs from surgeons A and B, respectively.

RESULTS

The moving average method revealed that the operation times of surgeons A and B began to shorten after the 9th case. The cumulative sum (CUSUM) analysis of group I data showed that the 24th case was the peak point of conversion. The 35th case was the peak for intraoperative complications, and the 17th case was the peak for postoperative complications. There was only one case of conversion in group II. The peak points for inadequate lymph node dissection were the 37th case in group I and the 8th case in group II. The CUSUM analysis for surgeons A and B showed that the 18th case and the 8th case, respectively, were the overall peak points in the failure of LRCCS.

CONCLUSIONS

We suggest that careful observation of a laparoscopic procedure, such as acting as the scope operator for a certain amount of time, may help in shortening the LC of the actual procedure.

Colorectal surgery in a community hospital setting: have attitudes changed because of laparoscopy? A general surgeons' last 5 years experience review

INTRODUCTION

Laparoscopy is rapidly emerging as the preferred surgical approach to a number of different diseases because it permits a correct diagnosis and accurate treatment; however, it is not yet being applied in a widespread manner in the management of benign or malignant colorectal disease. The aim of this work is to illustrate retrospectively the results of our experience of laparoscopic colorectal surgery carried out in a community hospital over the last 5 years to document its feasibility, safety, and benefits when carried out by general surgeons in this setting.

MATERIALS AND METHODS

Between January 2003 and December 2007 a total of 628 patients underwent a colorectal procedure. Among them, 328 (52.2%) were operated on with a laparoscopic approach.

RESULTS

In 12 cases, we had to convert to the open approach. Major complications occurred in 3.6% whereas minor occurrences occurred in up to 10%.

CONCLUSIONS

Even if limited by its retrospective design, our experience exhibits that the laparoscopic may well be a safe and effective approach to colon pathology in a community hospital setting. Such features make laparoscopy a challenging alternative to open surgery in the approach to colon disease and it can be proven to be cost-effective without undue risk, as long adequate laparoscopic training is undertaken by the surgeon and proper preparation observed.

Impact of hospital case volume on the quality of laparoscopic colectomy in Japan

INTRODUCTION

The increased use of laparoscopic colectomy for colon cancer requires the evaluation of hospital case volume, quality care, and training systems, considering the difficulty of this surgery for various tumor locations.

MATERIALS AND METHODS

We assessed the quality of this procedure in Japan, based on hospital case volume and tumor location. A total of 3,765 patients were enrolled across 567 hospitals between July and December 2007. We analyzed patient characteristics, postoperative surgical complications, the administration of stapling devices or chemotherapy, hospital volume and teaching status, postoperative length of stay, total charges, and operating room time. Hospitals were classified into four case-volume categories: high (> or =5 cases per month), intermediate to high (3-4), low to intermediate (1-2), and low (<1). Multivariate analysis was used to test the impact of hospital category and tumor location.

RESULTS

Ten high-volume hospitals performed 401 cases, while 355 low-volume hospitals did 903. Hospital case volume, operating time, and complications affected postoperative stay and total costs. Longer procedural time was an independent predictor of complications. Tumor location, case volume, and teaching status explained the variations in procedural time individually but not complications. Training systems highlighting the applicability of techniques are important to promote the quality of laparoscopic colectomy.

Impact of a full-time preceptor on the institutional outcome of laparoscopic colectomy

BACKGROUND

Laparoscopic assisted colectomy (LAC) is a difficult operation with long learning curves and conversion rates inversely proportional to the surgeon's experience. Methods to help train surgeons outside of residency or fellowship programs have been poorly analyzed. This study was undertaken to assess the impact of an experienced laparoscopic surgeon preceptor on the outcome of LAC in a single institution

METHODS

In September 2004, a fellowship-trained laparoscopic surgeon joined our department of surgery. This surgeon served as a LAC preceptor for six inexperienced staff surgeons and four surgical oncology fellows. Clinical and pathologic data from all attempted LAC for the 22 months preceding the arrival of the trained laparoscopic surgeon were compared with those for the 18 months following the recruitment.

RESULTS

Before the addition of the expert surgeon, 28 LAC were performed in our institution, compared with 63 during the preceptor program. These represented 59% and 95% of eligible operations for each time period, respectively (P = 0.005). Overall conversion rates before and after the preceptor's arrival decreased from 44% to 14%, respectively (P < 0.05). The chances of conversion were strongly affected by the presence or absence of the preceptor in the operating room (7% vs. 30%, respectively, P = 0.003). Overall complication rates, hospital stay, blood loss, operative time and number of lymph nodes retrieved were not affected by the presence of the preceptor. Operations completed laparoscopically resulted in significantly lower blood loss and length of stay compared with converted ones.

CONCLUSIONS

A shared departmental preceptor can positively affect the institutional outcome of laparoscopic colectomy. This model may help improve training and patient care in inexperienced centers.

Implementation of laparoscopic colectomy with fast-track care in an academic medical center: benefits of a fully ascended learning curve and specialty expertise

BACKGROUND

There are few data describing successful institutional "conversion" from open colectomy/standard care techniques to laparoscopic colectomy/fast-track care.

PURPOSE

To assess the benefits of transitioning an institution from open to laparoscopic colectomy with fast-track care while avoiding a learning curve.

METHOD

Twenty consecutive laparoscopic colorectal resections (LCRs) performed by a colorectal surgeon were compared with 20 matched open colorectal resections (OCRs) performed by general surgeons before the arrival of the colorectal surgeon.

RESULTS

Surgical procedures were as follows: sigmoidectomy: OCR 16 and LCR 11; right colectomy: OCR 3 and LCR 8; and total colectomy: OCR 1 and LCR 1. The mean operative time for sigmoidectomy was 250 and 109 minutes for OCR and LCR, respectively, and for right colectomy 181 and 97 minutes for OCR and LCR, respectively (P < .001). Morbidity was OCR 45% versus LCR 25%. There was no mortality. LCR showed significantly lower length of stay and direct cost (3.6 vs. 8.3 days; 4,993 dollars vs. 11,383 dollars; both P < .001).

CONCLUSIONS

The data clearly show an institutional benefit for the implementation of specialty-based advanced laparoscopic procedures.

A critical analysis of laparoscopic colectomy at a single institution: lessons learned after 1000 cases

BACKGROUND

A critical outcome analysis of a large, single-institution experience provides a better frame of reference for an assessment of the role of laparoscopic colectomy for colorectal pathology.

METHODS

Review of a prospectively gathered database was performed of a consecutive series of laparoscopic colectomy patients who were operated on by 2 surgeons at a single institution (tertiary referral center) using standardized techniques and care plans. Patients were assessed for operative indications, type of resection, operative time, conversion, complications, duration of stay, and readmission within 30 days.

RESULTS

One thousand consecutive patients undergoing laparoscopic colectomy from January 1999 thru June 2004 were analyzed. The types of resections were right colectomy = 314, left/sigmoid colectomy/anterior resection = 435, total colectomy = 61, total proctocolectomy = 14, and other = 176. The indications for surgery were diverticular disease = 285, colorectal neoplasia = 285, inflammatory bowel disease = 172, rectal prolapse = 81, and other = 177. The conversion rate was 11.4%. The mean operative time was 112 +/- 45 minutes for all resections. The mean duration of hospitalization for all patients was 3.7 +/- 3.8. The overall complication rate was 9.9%, with the most frequent complications being ileus 2.8%, pulmonary 1.6%, cardiac 1.4%, and wound infection 2.6%. The 30-day readmission rate was 9.1%, and the most frequent reasons for readmission were ileus/small-bowel obstruction, intra-abdominal infection, and anastomotic leak.

CONCLUSIONS

This largest single-institution experience with laparoscopic colectomy confirms the benefits of a standardized approach including shorter hospital rehabilitation and low rates of cardiopulmonary and wound complications. Efforts must be directed at improving access to training in laparoscopic colectomy techniques so that patients can benefit from this new technology.
