Laparoscopic colon surgery performed safely by general surgeons in a community hospital: a review of 154 consecutive cases

Laparoscopic liver resection: basic skills for peripheral lesions

An evaluation of the literature demonstrates atypical wedge or single segment resections to be the most commonly performed laparoscopic liver procedures. Lesions that are both visible on the surface of segments 2-6 and ≤2-3 cm can be resected by most surgeons holding a fundamental understanding of liver anatomy. These criteria are based on the anatomical circumstance that sectoral and segmental pedicles should not course through depths necessary to obtain negative margins for these sized and positioned lesions. Videos of laparoscopic liver resections referenced in PubMed demonstrate complex procedures that are rarely performed and assume an advanced skill set for laparoscopic dissection and transection of parenchyma and management of vascular and biliary structures. Herein is demonstrated basic skill for peripheral resections via two cases in one video, so that these procedures can be safely performed by surgeons with commonly available laparoscopic equipment.

Is laparoscopic right colectomy more effective than open resection? A meta-analysis of randomized and nonrandomized studies

AIM

The aim of this systematic review was to compare laparoscopic and/or laparoscopic-assisted right colectomy (LRC) with open right colectomy (ORC). Many randomized clinical trial have shown that laparoscopic colectomy benefits patients with improved short-term outcomes and comparable overall survival in respect to the open approach. These results, however, could not be applied to right colectomy owing to its wide range of resection and more complicated vascular regional anatomy.

METHOD

We performed a meta-analysis of the literature in order to compare LRC vs ORC by examining 21 end-points including operative and recovery outcomes, early postoperative mortality and morbidity, and oncological parameters. A subgroup analysis of patients undergoing right colectomy for cancer was carried out. The meta-analysis was conducted following all aspects of the Cochrane Handbook for systematic reviews and Preferred Reporting Items for Systematic Reviews and Metanalysis (PRISMA) statement. The search strategies were developed using the following electronic databases: PubMed, EMBASE, OVID, Medline, Cochrane Database of Systematic Reviews, EBM reviews and CINAHL until March 2011. We included randomized and non randomized studies that compared the LRC vs ORC for benign disease and malignant neoplasm irrespective of publication status. Only studies in English, French, German, Spanish and Italian languages were considered for inclusion. Emergency right colectomies were excluded. To perform the statistical analysis we used the odds ratio (OR) for categorical variables and the weighted mean difference (WMD) for continuous variables. An intention-to-treat analysis was performed.

RESULTS

Seventeen studies, 15 nonrandomized clinical trials and two randomized clinical trials, involving a total of 1489 patients, were identified. The mean operative time was longer in the group of patients undergoing LRC [weighted mean difference (WMD) = 37.94, 95% CI: 25.01 to 50.88; P < 0.00001]. Intra-operative blood loss (WMD = -96.61; 95% CI: -150.68 to -42.54; P = 0.0005), length of hospital stay (WMD = -2.29; 95% CI: -3.96 to -0.63; P = 0.007) and short-term postoperative morbidity (OR = 0.64; 95% CI: 0.49 to 0.83; P = 0.0009) were significantly in favour of LRC.

CONCLUSION

Laparoscopic-assisted right colectomy results in less blood loss, a shorter length of hospital stay and lower postoperative short-term morbidity compared with ORC.

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.

Laparoscopy decreases postoperative complication rates after abdominal colectomy: results from the national surgical quality improvement program

OBJECTIVE

Compare outcomes of non-emergent laparoscopic to open colon surgery.

BACKGROUND

Laparoscopy has revolutionized much of gastrointestinal surgery. Colon and rectal surgery has seen drastic changes with many of the abdominal operations being performed laparoscopically. However, data comparing recovery and complications in patients undergoing laparoscopic and open colon surgery has shown only slight benefits for laparoscopy. Given the large benefits of laparoscopy in most gastrointestinal surgical procedures, this outcome is surprising. We, therefore, have set out to test the hypothesis that laparoscopic approaches decreases postoperative complications.

METHODS

We have undertaken a review of the database maintained by the American College of Surgeon's National Surgical Quality Improvement Program. We have identified 8660 patients who met inclusion criteria for this study. Postoperative complication data were collected for patients undergoing laparoscopic or open colon surgery. Using a combination of univariate and multivariate analyses we evaluated for statistical significance.

RESULTS

We found that laparoscopy decreased overall complications as well as individual complications. We found a decreased length of stay as well as a decreased risk for postoperative complications in the elderly. We found that laparoscopy decreased complication rate independent of the probability of morbidity statistic.

CONCLUSIONS

When controlled for probability of morbidity, laparoscopy decreases the rate of postoperative complications. Given the equivalent outcomes of laparoscopic approaches, we conclude that laparoscopy should be offered to all patients who lack an absolute contraindication for laparoscopic surgery.

Laparoscopic colon resection by a single general surgeon in a community hospital: a review of 200 consecutive cases

BACKGROUND

We assessed a single surgeon's experience on laparoscopic colorectal surgery (LCR) at a single non academic, community hospital. The surgeon was trained in minimally-invasive techniques and robotic surgery with >500 procedures at another non-university hospital, either as operating surgeon or as assistant.

METHODS

Short-term outcome of patients undergoing LCR for benign/neoplastic disease (June 2005-September 2007) was assessed.

RESULTS

A total of 208 patients (104 males, 104 females; median age 69.1 years, Interquartile Range (IQR):59.3-76.6) underwent LCR. Over 70% of the operations were performed for cancer. Left hemicolectomy was performed in 102 patients (49.1%), right hemicolectomy in 50 (24%), anterior resection in 40 (19.2%), other procedures in 16 (7.7%). One-hundred-ninety (91.3%) operations were elective. The median operative time was 180 min (IQR:150-210). Conversion rate was 4.8%: 3.4% for benign and 5.4% for neoplastic disease (p = n.s.). The median lymph node harvest in cancer patients was 16 (IQR:12-20). Mortality and overall morbidity rates were 0.5% and 13%, with no significant difference between benign and malignant disease, colon and rectum, elective and non elective operations.

CONCLUSIONS

The outcomes of LCR surgery performed by a well-trained laparoscopic surgeon working in a community hospital are comparable with results from academic health science centers.

Minilaparoscopic colorectal resection: a preliminary experience and an outcomes comparison with classical laparoscopic colon procedures

BACKGROUND

Laparoscopy has rapidly emerged as the preferred surgical approach for a number of different diseases because it allows for a correct diagnosis and proper treatment. However, it is not being applied in a widespread manner for the management of benign or malignant colorectal disease. Its natural evolution seems to be the development of mini-instruments and optics (diameter, </=5 mm). This study aimed to illustrate retrospectively the results of an initial minilaparoscopic colorectal surgery experience at two different institutions.

METHODS

Between January 2001 and December 2006, a total of 517 patients underwent a laparoscopic colon procedure. Among them, 161 (31.1%) underwent surgery with mini-instruments. The primary end point was the feasibility rate for minilaparoscopic colon resection. The secondary end points were safety and the impact of the technique on the duration of laparoscopy.

RESULTS

No conversion to classical laparoscopy and eight cases converted to the open approach were registered. The rate for major complications was 3.1%, whereas the rate for minor complications ranged as high as 11.8%.

CONCLUSIONS

Even if limited by its retrospective design, the reported experience shows that minilaparoscopic surgery may be a safe and effective approach to colon pathology. The described features make minilaparoscopy a challenging alternative to laparoscopy for colon disease. If proven to be cost effective without undue risk, as long as adequate training is obtained and proper preparation is observed, minilaparoscopy may become a standard surgical approach for selected patients.

Implantación de la cirugía laparoscópica de colon en un servicio de cirugía general

OBJECTIVE

To evaluate the viability, safety and short-term results of laparoscopic colon surgery during the first few years after its introduction in our department.

METHOD

Between January 2002 and December 2005, laparoscopic surgery was performed in patients with surgical indication for benign colon disease. After 2003, patients with malignant disease were also included. A database was created and demographic data, surgical indication, technique, conversion rate, morbidity and postoperative length of stay were recorded. All patients were operated on by the same team of three surgeons.

RESULTS

Ninety consecutive patients, with a mean age of 59.2 years (20-88) underwent laparoscopic surgery. Of these, 53 were men (59%). In total, 32 patients had previously undergone one or more open laparotomies (35.5%). Surgery was indicated for benign disease in 60 patients (66%). Distribution was left colon in 79 patients and right colon in 11 patients. The most frequent technique was sigmoidectomy (67.7%). The conversion rate was 12.2%. Operating time was 199 min. (120-340) and length of postoperative stay was 7.5 days (4-57). Morbidity was 18.8% and mortality was 1.1%.

CONCLUSIONS

Laparoscopic surgery of the colon is safe and reproducible. Our short-term results are similar to those of previous studies. We believe that prior experience of laparoscopic surgery is important and that a stable surgical team minimizes the effect of the learning curve.

Advanced laparoscopic skills acquisition: the case of laparoscopic colorectal surgery

Acquisition of advanced technical skills requires commitment, time, patience, and discipline (eg, the 10-year rule). Dabbling is not a recipe for success. Despite the value of all other teaching methods, guided practice with feedback is essential to develop the high level of visuospatial perceptual ability (observation and performance with feedback) that is necessary for advanced MIS. The necessary ingredients to skill acquisition for advanced MIS procedures (laparoscopic colorectal surgery) for a practicing surgeon include introduction through short courses, access to skill stations, and access to preceptorship or mini-sabbatical. For residents in training, there is no better alternative than an MIS fellowship. In an ideal world where there are enough trainers, the residency environment should provide this training. Comprehensive strategies of knowledge transfer for practicing surgeons should be designed with the input of experts in knowledge transfer.
