A comparative study on the short-term clinicopathologic outcomes of laparoscopic surgery versus conventional open surgery for transverse colon cancer

Short-term outcomes of laparoscopic colectomy for transverse colon cancer

BACKGROUND

The role of laparoscopic surgery for transverse colon cancer (TCC) remains controversial. This study aimed to evaluate the safety of laparoscopic resection of TCC.

METHODS

Fifty-three patients undergoing laparoscopic resection of TCC (group A) were compared with 39 patients undergoing open resection of TCC (group B) and 200 patients undergoing laparoscopic resection of ascending or descending colon cancer (group C).

RESULTS

Mean operating time was longer (224 vs. 157 min), and mean estimated blood loss was lower (40 vs. 79 ml) in group A than in group B, but these were similar in groups A and C. The rates of conversion to open surgery were similar in groups A and C (1.9% vs. 1.0%). Tumor stage was more advanced in group B than in group A. All patients in groups A and B underwent pathologic R0 resection. The rates of postoperative complications did not differ significantly between groups (9.4% vs. 7.7% vs. 5.0%). Time to flatus (1.7 vs. 2.5 days), time to liquid diet (2.4 vs. 5.3 days), and hospital stay (12 vs. 15 days) were significantly shorter in group A than in group B, but similar in groups A and C.

CONCLUSIONS

Laparoscopic resection for TCC can be performed safely with similar short-term postoperative outcomes seen for colon cancer at other sites. Laparoscopic resection may be associated with faster gastrointestinal recovery and shorter length of hospital stay, compared with open surgery.

Breast models: a useful tool for instruction

Background

In the late '80s the successes of the laparoscopic surgery for gallbladder disease laid the foundations on the modern use of this surgical technique in a variety of diseases. In the last 20 years, laparoscopic colorectal surgery had become a popular treatment option for colorectal cancer patients.

Discussion

Many studies emphasized on the benefits stating the significant advantages of the laparoscopic approach compared with the open surgery of reduced blood loss, early return of intestinal motility, lower overall morbidity, and shorter duration of hospital stay, leading to a general agreement on laparoscopic surgery as an alternative to conventional open surgery for colon cancer. The reduced hospital stay may also decrease the cost of the laparoscopic surgery for colorectal cancer, despite th higher operative spending compared with open surgery. The average reduction in total direct costs is difficult to define due to the increasing cost over time, making challenging the comparisons between studies conducted during a time range of more than 10 years. However, despite the theoretical advantages of laparoscopic surgery, it is still not considered the standard treatment for colorectal cancer patients due to technical limitations or the characteristics of the patients that may affect short and long term outcomes.

Conclusions

The laparoscopic approach to colectomy is slowly gaining acceptance for the management of colorectal pathology. Laparoscopic surgery for colon cancer demonstrates better short-term outcome, oncologic safety, and equivalent long-term outcome of open surgery. For rectal cancer, laparoscopic technique can be more complex depending on the tumor location. The advantages of minimally invasive surgery may translate better care quality for oncological patients and lead to increased cost saving through the introduction of active enhanced recovery programs which are likely cost-effective from the perspective of the hospital health-care providers.
