Purpose: The purpose of this study was to evaluate the impact of laparoscopic colorectal resection on short-term postoperative outcome in elderly patients., Methods: A series of 535 patients with colorectal disease who had been randomly assigned to laparoscopic (n=268) or open (n=267) resection was analyzed. A total of 201 patients (37.6 percent) were elderly (aged 70 years or older) and 334 patients (62.4 percent) were younger than aged 70 years. Follow-up for postoperative morbidity was performed for 30 days after hospital discharge., Results: Elderly patients had a higher American Society of Anesthesiologists score compared with younger patients in both the laparoscopic and open groups (P=0.0001). In the open group, elderly patients had higher morbidity rate (37.5 vs. 23.9 percent; P=0.02) and longer length of hospital stay (13 vs. 10.6; P=0.007) compared with younger patients. In the laparoscopic group, morbidity rate (20.2 vs. 15.1 percent) and length of hospital stay (9.5 vs. 9.1) were similar in elderly and younger patients. In elderly patients, the laparoscopy-reduced morbidity rate (20.2 vs. 37.5 percent; P=0.01) and length of hospital stay (9.5 vs. 13; P=0.001) compared to the open approach. In younger patients, the advantages of the laparoscopic approach on morbidity rate (15.1 vs. 23.9 percent; P=0.06) and length of stay (9.1 vs. 10.6; P=0.004) were less pronounced., Conclusions: Laparoscopy improved short-term postoperative outcome more in elderly than in younger patients. Advanced age was associated with higher morbidity and longer length of stay only in patients who underwent open colorectal surgery.

Purpose: This study was designed to evaluate the impact of laparoscopic rectal resection on short-term postoperative morbidity and costs., Methods: A total of 168 patients with rectal cancer were randomly assigned to laparoscopic (n = 83) or open (n = 85) resection. Outcome parameters were: postoperative morbidity, length of hospital stay, quality of life, long-term survival, and local recurrences. The mean follow-up period was 53.6 months. Cost-benefit analysis was based on hospital costs., Results: Operative time was 53 minutes longer in the laparoscopic group (P < 0.0001). Postoperative morbidity rate was 28.9 percent in the laparoscopic vs. 40 percent in the open group (P = 0.18). The mean length of hospital stay was 10 (4.9) days in the laparoscopic group and 13.6 (10) days in the open group (P = 0.004). Local recurrence rate and five-year survival were similar in both groups; however, the limited number of patients does not allow firm conclusions. Quality of life was better in the laparoscopic group only in the first year after surgery (P < 0.0001). The additional charge in the laparoscopic group was $1,748 per patient randomized ($1,194 the result of surgical instruments and $554 the result of longer operative time). The saving in the laparoscopic group was $1,396 per patient randomized ($647 the result of shorter length of hospital stay and $749 the result of the lower cost of postoperative complications). The net balance resulted in $351 extra cost per patient randomly allocated to the laparoscopic group., Conclusions: Short-term postoperative morbidity was similar in the two groups. Laparoscopic resection reduced length of hospital stay, improved first-year quality of life, and slightly increased hospital costs.

Purpose: This study was designed to evaluate long-term complications, quality of life, and survival rate in a series of colorectal cancer patients randomized to laparoscopic or open surgery., Methods: A total of 391 patients with colorectal cancer were randomly assigned to laparoscopic (n = 190) or open (n = 201) resection. Long-term follow-up was performed every six months by office visits. Quality of life was assessed at 12, 24, and 48 months after surgery by a modified version of Short Form 36 Health Survey questionnaire. All patients were analyzed on an intention-to-treat basis., Results: Eight (4.2 percent) laparoscopic group patients needed conversion to open surgery. Overall long-term morbidity rate was 6.8 percent (13/190) in the laparoscopic vs. 14.9 percent (30/201) in the open group (P = 0.018). Overall quality of life was significantly better in the laparoscopic group in the first 12 months after surgery, whereas at 24 months, patients of the laparoscopic group reported a significant advantage only in social functioning. No difference was found in both overall and disease-free survival rates by comparing laparoscopic vs. open group., Conclusions: Laparoscopic colorectal resection was associated with a lower incidence of long-term complications and a better quality of life in the first 12 months after surgery compared with open surgery. No difference between groups was found in overall and disease-free survival rates.

Purpose: The aim of this study was to evaluate whether laparoscopic colorectal surgery can modify the risk factors for the occurrence of postoperative morbidity., Methods: A total of 384 consecutive patients with colorectal disease were randomized to laparoscopic resection (n = 190) or open resection (n = 194). On admission, demographics, comorbidity, and nutritional status were recorded. Operative variables, patient outcome, and length of stay were also recorded. Postoperative complications were registered by four members of staff not involved in the study., Results: The overall morbidity rate was 27.1 percent, with the rate in the laparoscopic group (18.7 percent) being less than that in the open group (31.5 percent; P = 0.003). Patients who underwent laparoscopic resection had a faster recovery of bowel function (P = 0.0001) and a shorter length of stay (P = 0.0001). In the whole cohort of patients, multivariate analysis identified open surgery (P = 0.003), duration of surgery (P = 0.01), and homologous blood transfusion (P = 0.01) as risk factors for postoperative morbidity. In the open group, blood loss (P = 0.01), homologous blood transfusion (P = 0.01), duration of surgery (P = 0.009), weight loss (P = 0.06), and age (P = 0.08) were related to postoperative morbidity. In the laparoscopic group the only risk factor identified was duration of surgery (P = 0.005)., Conclusion: In the laparoscopic group, both postoperative morbidity and length of stay were significantly reduced and most risk factors for postoperative morbidity disappeared.

Purpose: This study was designed to compare metabolic and functional results after laparoscopic and open colorectal resection., Methods: Seventy-nine patients were randomly assigned to laparoscopic (n = 40) or open (n = 39) colorectal resection. Before and after operation, the following parameters were determined: respiratory function (spirography and blood gas); serum level of cortisol, lactate, and C-reactive protein; total lymphocyte count; and CD4 and CD8 lymphocyte subsets. Intraoperative core temperature was measured by a bladder probe. Postoperative pain and analgesic consumption were also monitored., Results: Mild operative hypothermia, a trend to postoperative reduction of total lymphocyte count, and significant impairment of respiratory function early after surgery were found in both groups. Laparoscopy showed a higher CD4/CD8 ratio (P = 0.01) on postoperative Day 1 and a faster return of C-reactive protein to preoperative values (P = 0.01) than in the open colorectal resection group. Morphine consumption in the first 48 hours after surgery was lower in the laparoscopic than in the open group (P = 0.02)., Conclusions: Laparoscopy was associated with a less pronounced immunosuppression and inflammatory response and a lower consumption of analgesic drugs than open surgery. Moreover, our data did not show any additional detrimental effect of laparoscopy on either operative core temperature or early postoperative respiratory function.
