Current Role of Therapeutic Laparoscopy and Thoracoscopy in the Management of Malignancy: A Review of Trends from a Tertiary Care Cancer Center

Evolving application of minimally invasive cancer operations at a tertiary cancer center

BACKGROUND

Patients and providers are increasingly interested in the utilization, safety, and efficacy of minimally invasive surgery (MIS). We reviewed 11 years of MIS resections (laparoscopic and robotic) for intra-abdominal malignancies.

METHODS

Patients who underwent gastrectomy, distal pancreatectomy, hepatic resection, and colorectal resection between 2004 and 2014 were identified. Cases were categorized as open, laparoscopic, and robotic based on the initial operation approach. Diagnostic laparoscopies were excluded.

RESULTS

Of the 10 039 patients who underwent the above procedures, between 2004 and 2014, 2832 (28%) were MIS. In 2004, 12% (100/826) of all resections were performed with MIS approaches, rising to 23% (192/821) of all resections by 2009 and 44% (484/1092) in 2014. The number of open resections has remained largely stable: 726 (88% of all resections) in 2004 and 608 (56% of all resections) in 2014. Initially, laparoscopy experienced incremental adoption. Robotic surgery was implemented in 2009 and is currently the dominant MIS approach, accounting for 76% (368/484) of all MIS resections in 2014. Overall mortality has remained less than 1%.

CONCLUSIONS

While maintaining patient safety, utilization of MIS techniques has increased substantially since 2004, particularly for gastric and colorectal resections. Since 2009 robotic surgery is the predominant MIS approach.

Hand-assisted laparoscopic total gastrectomy with regional lymph node dissection for advanced gastric cancer

BACKGROUND AND OBJECTIVES

Laparoscopic-assisted distal gastrectomy has been applied to the treatment of gastric cancer. However, there have been few reports on the laparoscopic-assisted total gastrectomy for advanced gastric cancer, mainly because of the difficulty of the procedure.

METHODS

Here, we report a series of cases where the hand-assisted laparoscopic total gastrectomies with regional lymph node dissection were performed successfully.

RESULTS

The average operative time was 245 minutes. The mean blood loss was 110 mL. The number of dissected lymph nodes per patient was beyond 15 nodes satisfying a reliable evaluation of nodal status. All resection specimens had no residual tumor at the proximal or distal resection margins. The mean oral feeding was 3.6 days. The mean postoperative length of stay was 8.7 days.

CONCLUSIONS

The hand-assisted laparoscopic D2 total gastrectomy for advanced gastric cancer is both technically feasible and safe.

Best practices for minimally invasive procedures

Techniques and instrumentation for minimally invasive surgical procedures originated in gynecologic surgery, but the benefits of surgery with small incisions or no incisions at all have prompted the expansion of these techniques into numerous specialties. Technologies such as robotic assistance, single-incision laparoscopic surgery, natural orifice transluminal endoscopic surgery, and video-assisted thoracoscopic surgery have led to the continued expansion of minimally invasive surgery into new specialties. With this expansion, perioperative nurses and other members of the surgical team are required to continue to learn about new technology and instrumentation, as well as the techniques and challenges involved in using new technology, to help ensure the safety of their patients. This article explores the development of minimally invasive procedures and offers suggestions for increasing patient safety.

Totally laparoscopic gastric resection with extended lymphadenectomy for gastric adenocarcinoma

BACKGROUND

Laparoscopic gastric resection with extended lymphadenectomy is being evaluated in North America for the surgical treatment of gastric cancer. The aim of this study is to compare short-term postoperative and oncologic outcomes of laparoscopic and open resection for gastric cancer at a single cancer center.

METHODS

The study population consisted of patients with gastric adenocarcinoma who underwent a completely abdominal intervention with curative intent. Laparoscopic and open gastric resections were compared. A totally laparoscopic technique was employed with a robotic extended lymphadenectomy in a subset of patients.

RESULTS

A total of 78 consecutive patients were evaluated, including 30 laparoscopic and 48 open procedures. An extended lymphadenectomy was performed in 58 patients and was executed robotically in 16 of these. There was no difference in the mean number of lymph nodes retrieved by laparoscopic or open approach (24 +/- 8 vs. 26 +/- 15, P = .66). Laparoscopic procedures were associated with decreased blood loss (200 vs. 383 mL, P = .0009) and length of stay (7 vs. 10 days, P = .0009), but increased operative time (399 vs. 298 minutes, P < .0001).

CONCLUSION

Completely laparoscopic gastric resection yields similar lymph node numbers compared with open surgery for gastric cancer. It was found to be advantageous in terms of operative blood loss and length of stay. Minimally invasive techniques represent an oncologically adequate alternative for the surgical treatment of gastric adenocarcinoma.
