Early outcomes of colon laparoscopic resection in the elderly patients compared with the younger

Impact of age and comorbidities on colorectal endoscopic submucosal dissection outcomes: Large multicenter study in a Western cohort

Background and study aims

Endoscopic submucosal dissection (ESD) has emerged as the standard treatment for colorectal lesions. Considering aging of the global population, we aimed to assess effectiveness and safety of colorectal ESD in patients aged ≥ 80 years compared with those aged 65 to 79 years in a large Western cohort.

Patients and methods

We retrospectively enrolled patients aged > 64 years undergoing colorectal ESD, classifying them into a very elderly group (VE-Group, aged > 80 years) and elderly group (E-Group, 65-79 years). Procedure outcomes and safety were compared between the VE-Group and E-Group and between patients with comorbidities and those who were healthy (1-CM-Group and H-Group).

Results

A total of 980 patients were included (269; 27.5% in the VE-Group and 711; 72.5% in the E-Group). En-bloc, R0, and oncological curative resection rates did not differ, nor did intra-procedure or post-procedure adverse events (AEs). Delirium occurrence was registered in VE-group [6 (2.2%) in VE-Group vs 1 (0.1%) in E-Group; P = 0.001; OR = 16.2, (95%CI:1.9-135.2)]. The 1-CM-Group had a higher rate of intra-procedure bleeding ( P = 0.001), delayed perforation ( P = 0.03), fever onset ( P < 0.001), and systemic infections ( P = 0.02) compared with the H-Group. Having one or more comorbidities was associated with increased overall AEs ( P < 0.001; OR 2.3, 95% CI 1.5-3.6).

Conclusions

Colorectal ESD is feasible in elderly patients. Physicians should consider delirium a possible AE in patients older than age 80 years. These findings, which bridge the gap between Asian and Western clinical data, underscore the importance of tailored pre-procedure and post-procedure assessments in a global clinical context.

National disparities in use of minimally invasive surgery for rectal cancer in older adults

BACKGROUND

Minimally invasive surgery (MIS) is safe and improves outcomes in older persons with rectal cancer but may be underutilized. As older persons are the largest surgical population, investigation of the current use and factors impacting MIS use is warranted. Our goal is to investigate the trends and disparities that affect utilization of MIS in older persons with rectal cancer.

METHODS

The National Cancer Database was reviewed for persons 65 years and older who underwent curative resection for rectal adenocarcinoma from 2010 to 2017. Cases were stratified by surgical approach (open or MIS [laparoscopic or robotic]). Univariate analysis compared patient and provider demographics across approaches. Multivariate analysis investigated variables associated with MIS use. Main outcome measures were trends and factors associated with MIS use in older persons.

RESULTS

Of 31,910 patients analyzed, 51.9% (n = 16,555) were open and 48.1% (n = 15,355) MIS. The MIS cohort was 66.7% (n = 10,236) laparoscopic and 33.3% (n = 5119) robotic. MIS increased from 29% in 2010 (n = 1197; 25% laparoscopic, 4% robotic) to 65% in 2017 (n = 2382; 35% laparoscopic, 30% robotic), likely from annual increases in robotics (OR 1.24/year, p < 0.0001). In the unadjusted analysis, there were significant differences in MIS use by age, race, comorbidity, socioeconomic status, and facility type. In multivariate analysis, patients with advancing age (OR 0.93, p < 0.001), major comorbidity (OR 0.75, p < 0.001), total proctectomy (OR0.78, p < 0.001), and advanced pathologic stage (OR 0.51, p < 0.001) were less likely to undergo MIS.

CONCLUSION

Nationwide, less than half of rectal cancer cases in older persons were performed with MIS, despite steady robotic growth. Patient and facility factors impacted MIS use. Further work on regionalizing rectal cancer care and ensuring equitable MIS access and training could improve utilization.

Robotic surgery for colorectal cancer in the Octogenarians

BACKGROUND

We evaluated the short-term outcomes of robotic colorectal cancer surgery in octogenarian patients, focussing on postoperative morbidity and survival.

METHODS

All patients ≥80 years in a prospective colorectal cancer database undergoing robotic curative colorectal cancer resection were included. Patient demographics, intraoperative findings, postoperative and oncological outcomes were recorded. Patients were further subdivided into two groups named: old (OG 80-85 years) and very old (VOG ≥ 86 years).

RESULTS

Fifty-eight consecutive patients were included (median age, 83 years; male, 53.4%; median BMI, 26.5). Median total operative time was 230 min, median blood loss 20 ml, median length of stay 7 days. Major complications were seen in 12% of patients; and the 90-day mortality rate was 1.7%. Complete R0 resection achieved in 93% of cases, average lymph node harvest was 22. Overall and disease-free survival was 81% and 87.3%, respectively (median follow-up 24.5 months). We noticed a trend towards more advanced lesion staging in the VOG, but only N2 stage was significant (p = 0.03). There was a statistically significant difference in overall survival in favour of the OG (p = 0.024).

CONCLUSIONS

Robotic surgery is feasible in octogenarian patients undergoing curative colorectal cancer resection and is associated with good post-operative outcomes and overall survival.

Minimally invasive surgery in the geriatric patient with colon cancer

As the global population ages, the number of geriatric patients requiring surgery for colon cancer would inevitably increase. Radical oncological surgery in the elderly colorectal cancer patient has been recognized to be associated with a higher rate of postoperative complications and mortality compared to the young. While less aggressive management options may be reasonable in patients with limited life expectancy and significant comorbidities, many elderly patients have preserved function despite their chronological age. The advances in minimally invasive surgery (MIS) now provide a feasible means of achieving safe oncological treatment for these geriatric patients. This review focuses on the evidence behind MIS in the geriatric patient with colon cancer.

A National study on the adoption of laparoscopic colorectal surgery in the elderly population: current state and value proposition

BACKGROUND

The economic and clinical benefits of laparoscopic colorectal surgery are proven, yet may be underutilized in appropriate cases, especially in the elderly. Since the elderly constitute the greatest colorectal surgical volume, our goal was to identify trends in utilization and impact of laparoscopy in this cohort.

METHODS

A national review of elective inpatient colorectal resections from the Premier Inpatient Database between 2010 and 2015 was performed. Patients were included if elderly (≥ 65 years), then grouped into open or laparoscopic procedures. The main outcome measures were trends in utilization by approach and total costs for the episode of care, length of stay (LOS), readmission, and complications by approach in the elderly. Multivariable regression models controlled for differences across platforms, adjusting for patient demographic, comorbidities and hospital characteristics.

RESULTS

In 70,655 elderly patients evaluated, laparoscopic adoption remained lower than open throughout the study period. Rates increased until 2013, then declined, with increasing rates of open surgery. Laparoscopy was associated with significantly lower mean total costs ($4012 less/case), complications and readmissions (36% and 33% less, respectively), and shorter LOS (2.6 less days) than open cases (all p < 0.0001). When complications occurred, they were less severe and the readmission episodes were less costly with laparoscopy than open colorectal surgery.

CONCLUSION

The adoption of laparoscopy in the elderly has lagged behind open surgery and even declined in recent years despite being associated with improved clinical outcomes and reduced cost. With this tremendous value proposition to increase use of laparoscopic surgery in the elderly, further work needs to evaluate root causes of the disparity.

Short-term outcomes of laparoscopic surgery for colorectal cancer in the elderly versus non-elderly: a systematic review and meta-analysis

PURPOSE

Laparoscopic surgery for colorectal cancer has spread globally. The usefulness of laparoscopic surgery for elderly patients was initially indicated by comparison with open surgery. However, whether the procedure is safe for elderly as well as non-elderly patients with colorectal cancer remains unclear.

METHODS

In this review, patients aged ≥ 75 were defined as elderly. We conducted literature searches using PubMed, Scopus, and the Cochrane Central Register of Clinical Trials. Two authors independently reviewed resultant articles to identify relevant observational studies. Data synthesis was performed with a random-effects model. Heterogeneity was investigated by using forest plots and I² statistics. Risk of bias of included studies was assessed by the Risk of Bias Assessment Tool for Nonrandomized Studies. Publication bias was assessed by funnel plots.

RESULTS

Twenty-two studies were included. The incidence of overall complications was slightly higher in elderly patients than in non-elderly patients, with statistical significance (risk ratio (RR) 1.20, 95% confidence interval (CI) 1.08-1.34). There was no difference between them in the incidence of anastomotic leakage (RR 1.24, 95% CI 0.86-1.80) and mortality (risk difference 0.00, 95% CI - 0.01 to 0.01).

CONCLUSIONS

Laparoscopic surgery for colorectal cancer is mostly safe for elderly patients as well as non-elderly patients. Preoperative comorbidities or poor physical capacity should be cared for in the elderly.

[Efficacy of video-assisted procedures in advanced age patients with colorectal cancer]

AIM

To assess advisability of video-assisted surgery in advanced age patients with colorectal cancer.

MATERIAL AND METHODS

The study involved 44 patients with large intestine tumors. There were 30 patients with colon cancer aged 78.0±1.1 years and 14 patients with rectal neoplasms aged 75.0±1.8 years. All of them underwent elective video-assisted resections without conversion of the approach.

RESULTS

Good and satisfactory results were achieved in 95.5% of patients. Postoperative complications occurred in 5 (11.4%) cases followed by redo surgery in 2 (4.5%) patients. Mortality was absent.

CONCLUSION

Video-assisted procedures are preferable in elective surgery of colorectal cancer in advanced age patients regardless stage and localization of the process.

Evaluation of safety, feasibility and the long-term outcomes of colorectomy for colorectal adenocarcinoma in patients older than 80 years of age

The short- and long-term outcomes of colorectomy for colorectal adenocarcinoma have not been fully evaluated in elderly patients. The present retrospective study investigated patients who underwent curative surgery for colorectal cancer at the Department of Surgery, Yokohama City University (Yokohoma, Japan). The patients were categorized into two groups: Elderly patients (70-79 years of age; group A) and extremely elderly patients (≥80 years of age; group B). The rates of surgical morbidity, surgical mortality, overall survival (OS), and recurrence-free survival (RFS) in the two groups were compared. A total of 191 patients were evaluated in the current study. Of these, 137 patients were included in group A, and 54 were included in group B. With the exception of the American Society of Anesthesiology physical status score, there were no significant differences in the preoperative clinicopathological outcomes of the two groups. The overall complication rates in groups A and B were 12.4 and 16.7%, respectively, and did not differ to a statistically significant extent (P=0.440). In addition, surgical mortality was not observed in either group. The 5-year OS and RFS rates were similar between the group A and B patients (75.6 vs. 76.9%; P=0.5537; and 71.9 vs. 62.2%; P=0.192, respectively). The short-term outcomes and long-term survival following colorectomy for colorectal adenocarcinoma among patients in the 70-79 years of age group, and those who were ≥80 in the current study were almost equal. Thus, it is not necessary to avoid colorectomy for colorectal adenocarcinoma in elderly patients simply because of their age.

Short- and long-term outcomes of laparoscopic surgery for colorectal cancer in the elderly: A prospective cohort study

BACKGROUND

The aim of this study was to evaluate the safety and validity of laparoscopic colorectal surgery for elderly patients. We compared the short and long-term postoperative outcomes of laparoscopic colorectal surgery in patients aged ≥75 years (elderly patients; EP) and <75 years (relatively younger patients; RP).

METHODS

Clinicopathological data and short- and long-term outcomes after laparoscopic surgery for colorectal cancer were compared between the EP (n = 53) and RP groups (n = 155).

RESULTS

In the EP group, patients with American Society of Anesthesiologists score II (p = 0.047) and medical comorbidity rate (EP vs RP: 83.0% vs 56.8%, p < 0.001), especially for cardiovascular disease (64.2% vs 37.5%, p < 0.001) and diabetes mellitus (20.8% vs 9.7%, p = 0.044), were significantly higher than those in the RP group. Regarding the clinical characteristics, the ratio of right colectomy (50.9% vs 25.3%, p < 0.001) and pathological tumor grade T4 (18.9% vs 7.7%, p = 0.044) were significantly higher in the EP group. There was no significant difference in the variation of pathological stage between the two groups. In the postoperative course, there were no significant differences regarding short-term postoperative outcomes between the EP and RP groups, including that for timing of oral diet tolerance (3.9 days vs 3.5 days, p = 0.073), first flatus (2.3 days vs 2.0 days, p = 0.636), first bowel movement (3.3 days vs 3.7 days, p = 0.153), ambulation after surgery (1.7 days vs 1.5 days, p = 0.081), postoperative hospital stay (10.5 days vs 10.8 days, p = 0.469), and incidence of postoperative complications (20.8% vs 15.5%, p = 0.385), respectively. Regarding the long-term outcomes, there were no significant differences in recurrence-free survival (RFS) (5-year RFS, 74.0% vs 85.2%, p = 0.091) and overall survival (OS) (5-year OS, 81.8% vs 90.1%, p = 0.112) between the two groups.

CONCLUSION

Laparoscopic colorectal surgery in elderly patients was safe and well-tolerated in comparison with the relatively younger patients.

Age Over 80 is a Possible Risk Factor for Postoperative Morbidity After a Laparoscopic Resection of Colorectal Cancer

Purpose

With extended life expectancy, the mean age of patients at the time of diagnosis of colorectal cancer and its treatment, including radical resection, is increasing gradually. We aimed to evaluate the impact of age on postoperative clinical outcomes after a laparoscopic resection of colorectal cancers.

Methods

This is a retrospective review of prospectively collected data. Patients with primary colorectal malignancies or premalignant lesions who underwent laparoscopic colectomies between January 2009 and April 2013 were identified. Patients were divided into 6 groups by age using 70, 75, and 80 years as cutoffs: younger than 70, 70 or older, younger than 75, 75 or older, younger than 80, and 80 or older. Demographics, pathological parameters, and postoperative clinical outcomes, including postoperative morbidity, were compared between the younger and the older age groups.

Results

All 578 patients underwent a laparoscopic colorectal resection. The overall postoperative complication rate was 21.1% (n = 122). There were 4 cases of operative mortality (0.7%). Postoperative complication rates were consistently higher in the older groups at all three cutoffs; however, only the comparison with a cutoff at 80 years showed a statistically significant difference between the younger and the older groups.

Conclusion

Age over 80 is a possible risk factor for postoperative morbidity after a laparoscopic resection of colorectal cancer.

Disparities in the Utilization of Laparoscopic Surgery for Colon Cancer in Rural Nebraska: A Call for Placement and Training of Rural General Surgeons

BACKGROUND

Advances in medical technology are changing surgical standards for colon cancer treatment. The laparoscopic colectomy is equivalent to the standard open colectomy while providing additional benefits. It is currently unknown what factors influence utilization of laparoscopic surgery in rural areas and if treatment disparities exist. The objectives of this study were to examine demographic and clinical characteristics associated with receiving laparoscopic colectomy and to examine the differences between rural and urban patients who received either procedure.

METHODS

This study utilized a linked data set of Nebraska Cancer Registry and hospital discharge data on colon cancer patients diagnosed and treated in the entire state of Nebraska from 2008 to 2011 (N = 1,062). Multiple logistic regression analysis was performed to identify predictors of receiving the laparoscopic treatment.

RESULTS

Rural colon cancer patients were 40% less likely to receive laparoscopic colectomy compared to urban patients. Independent predictors of receiving laparoscopic colectomy were younger age (<60), urban residence, ≥3 comorbidities, elective admission, smaller tumor size, and early stage at diagnosis. Additionally, rural patients varied demographically compared to urban patients.

CONCLUSIONS

Laparoscopic surgery is becoming the new standard of treatment for colon cancer and important disparities exist for rural cancer patients in accessing the specialized treatment. As cancer treatment becomes more specialized, the importance of training and placement of general surgeons in rural communities must be a priority for health care planning and professional training institutions.

Complicated postoperative recovery increases omission, delay and discontinuation of adjuvant chemotherapy in patients with Stage III colon cancer

AIM

The study included investigation of factors determining suboptimal adjuvant chemotherapy of patients diagnosed with Stage III colon cancer.

METHOD

All 606 patients diagnosed with Stage III colon cancer between 2006 and 2008 in the western part of the Netherlands were included. Patient [gender, age, comorbidity and socio-economic status (SES)], tumour (location, stage and grade) and treatment (emergency surgery, laparoscopic surgery, reoperation, hospital stay and multidisciplinary meeting) factors were examined in logistic regression analyses predicting a complicated postoperative period and omission, delay and discontinuation of adjuvant chemotherapy.

RESULTS

Overall, 27% of all patients experienced a complicated postoperative period, which was independently associated with emergency surgery, older age, multiple comorbidity, male gender and poor tumour grade. Of patients who survived this period, 60% received chemotherapy. Chemotherapy was omitted more often in women, the elderly and in patients with Stage IIIB, reoperation, prolonged hospital stay and (borderline) after open surgery. Of patients who received chemotherapy, 86% started within 8 weeks after surgery. Patients with a higher SES, reoperation and prolonged hospital stay had a higher probability of a delayed start. Sixty-seven per cent of patients completed their chemotherapy. For women, elderly patients and patients with prolonged hospital stay a higher probability of discontinuation was noted.

CONCLUSION

Age was the most important predictive factor for receiving adjuvant chemotherapy. However, at all ages, complicated postoperative recovery negatively influenced the administration of chemotherapy to Stage III colon cancer patients, as well as a timely start and completion of chemotherapy.

Are there any differences between age groups regarding colorectal surgery in elderly patients?

BACKGROUND

Surgical procedures with curative or palliative intentions in subjects aged over 70 represent a colorectal surgical challenge due to the issue they raise: Benefits versus increased morbidity. In this study, we proposed to compare the impact of surgery with the surgical intervention short-term results and analyze the factors that may influence these results in elderly age groups.

METHODS

We retrospectively analyzed a database containing information about patients who underwent colorectal surgery from January 2008 to December 2013 at the Baskent University Istanbul Research Hospital and the Okmeydani Training and Research Hospital.

RESULTS

A total of 265 patients were enrolled and analyzed in this retrospective study. Of these patients operated during the study period, 110 were between 60 and 69 years of age (group 1), 99 were between 70 and 79 years of age and 56 were older than 80 years of age. In total, there were 138 (52%) men and 127 (48%) women that underwent colorectal surgery. Intraoperative complications did not differ between group 1 and group 2, group 2 and group 3; however, some differences were observed between group 1 and group 3 (p = 0.001). Systemic complications were more frequent in group 3 than in groups 1 (p = 0.039) and 2 (p = 0.002). Furthermore, there were no significant systemic complication differences between groups 1 and 2. The mean length of postoperative hospital stay was 9.91 ± 2.65 days in the first group, 9.38 ± 2.44 days in the second group and 11.8 ± 4.35 days in the third group.

CONCLUSION

Colon surgery for both malignant and non-malignant diseases can be performed safely in different elderly age groups; thus, age should not be considered as an obstacle in elderly patients undergoing colorectal resection.

[Treatment reality with respect to laparoscopic surgery of colonic cancer in Germany]

BACKGROUND

Prospective randomized studies and meta-analyses have shown that laparoscopic resection for colonic cancer is equivalent to open resection with respect to the oncological results and has short-term advantages in the early postoperative outcome. The aim of this study was to investigate whether laparoscopic colonic resection has become established as the standard in routine treatment.

METHODS

Data from the multicenter observational study "Quality assurance colonic cancer (primary tumor)" from the time period from 1 January 2009 to 21 December 2011 were evaluated with respect to the total proportion of laparoscopic colonic cancer resections and tumor localization and specifically for laparoscopic sigmoid colon cancer resections. A comparison between low and high volume clinics (< 30 versus ≥ 30 colonic cancer resections/year) was carried out.

RESULTS

Laparoscopic colonic cancer resections were carried out in 12 % versus 21.4 % of low and high volume clinics, respectively (p < 0.001) with a significant increase for low volume clinics (from 8.0 % to 15.6 %, p < 0.001) and a constant proportion in high volume clinics (from 21.7 % to 21.1 %, p = 0.905). For sigmoid colon cancer laparoscopic resection was carried out in 49.7 % versus 47.6 % (p = 0.584). Differences were found between low volume and high volume clinics in the conversion rates (17.3 % versus 6.6 %, p < 0.001), the length of the resected portion (Ø 23.6 cm versus 36.0 cm, p < 0.001) and the lymph node yield (Ø n = 15.7 versus 18.2, p = 0.008). There were no differences between the two groups of clinics regarding postoperative morbidity and mortality. The postoperative morbidity and length of stay were significantly lower for laparoscopic sigmoid resection than for conventional sigmoid resection.

CONCLUSION

The laparoscopic access route for colonic cancer resection is not the standard approach in the participating clinics. The laparoscopic access route has the highest proportion for sigmoid colon resection. The differences in the conversion rates, length of the resected portion and the number of lymph nodes investigated between the low volume and high volume clinics must be viewed critically and must be interpreted in connection with the long-term oncological results.

Potentially resectable metastatic colorectal cancer: an individualized approach to conversion therapy

Colorectal cancer is one of the most common cancers worldwide. In recent years, the survival of patients with metastatic disease has improved due to the developments in both medical and surgical care. Patients with technically unresectable metastatic disease could benefit from a multidisciplinary approach for their possible shift toward a technically resectable condition; the choice of the most effective systemic treatment is then crucial to allow conversion to resectability. Systemic conversion therapy may include chemotherapy agents' combinations (fluoropyrimidine, irinotecan and oxaliplatin), with or without targeted agents (cetuximab, panitumumab, bevacizumab). The choice of the best treatment option has to be evaluated by taking into account each patient's baseline characteristics, biological and pathological information and surgical strategy. In particular, the role of some biologic characteristics of the disease, namely the mutational status of EGFR-pathway oncogenes, is emerging as an important predictive factor of response to anti-EGFR targeted agents. Patients presenting with colorectal cancer metastases should be evaluated for multimodal management with curative intent as the appropriate chemotherapy regimen may induce tumor shrinkage, conversion to resectability and improved survival.

Using frailty to predict who will fail early discharge after laparoscopic colorectal surgery with an established recovery pathway

BACKGROUND

Despite laparoscopy and enhanced recovery pathways, some patients do not attain early discharge. Frailty is generally accepted as a marker of increased risk, complications, and mortality. Frailty may have the potential to identify patient outcomes.

PURPOSE

The aim of this study was to evaluate frailty as a predictor of patients who might fail early discharge.

SETTING

This study was conducted at a tertiary referral center.

DESIGN

This was a case-matched study.

PATIENTS

Elective abdominal laparoscopic colorectal cases from 2009 to 2012 were selected.

METHODS

Review of a prospective database matched all cases with a postoperative day of discharge of ≤3 days to a >3 day of discharge cohort. All patients followed a standardized enhanced recovery pathway.

STATISTICAL ANALYSIS

Categorical and ordinal variables were analyzed with the Student t test or Fisher exact test, and correspondence analysis evaluated the relationship between length of stay and the Modified Frailty Index.

MAIN OUTCOME MEASURE

The primary outcome measure was the relationship between length of stay and the Modified Frailty Index.

RESULTS

There were 464 ≤3 day and 388 >3 day patients. The groups were similar in demographics and comorbidities. There were significant differences in the Modified Frailty Index (p < 0.01), operative time (p < 0.01), postoperative complications (p < 0.01), 30-day readmissions (p = 0.03), and 30-day reoperation rate (p < 0.01). Significantly more patients were discharged home in the ≤3 day cohort. Correspondence analysis demonstrated a higher Modified Frailty Index was indicative of longer length of stay. A Modified Frailty Index of 0 was strongly related to a length of stay 0 to 3 days, and a Modified Frailty Index of 2 was strongly related to a 8- to 14-day stay.

LIMITATIONS

This was a single-center study performed on a retrospective data set.

CONCLUSIONS

Patients undergoing elective colorectal surgery with a higher Modified Frailty Index were more likely not to attain early discharge. Despite similar demographics, the Modified Frailty Index could discriminate between patient outcomes, and correlated with longer operating times, length of stay, and readmissions. By using a prospective score to identify patients at risk for not achieving early discharge preoperatively, resources and postoperative support can be better allocated.

[Personalized treatment of colorectal cancer in old age]

The incidence of colorectal cancer in elderly patients is rising. Due to changing demographics the topic of personalized treatment of colorectal cancer in old age is of growing importance for interdisciplinary tumor therapy. Besides the oncological results for this group of patients, aspects of risk consideration for treatment, quality of life and the personal conception of life become more relevant. This report covers the changes in comorbidities associated with old age and illustrates the impact on therapeutic strategies and results. Furthermore, it exemplifies potential individual adaption of standardized therapy regimens in multimorbid patients and provides information on possible strategies to improve treatment outcome.

Optimizing cost and short-term outcomes for elderly patients in laparoscopic colonic surgery

BACKGROUND

Elderly patients often are regarded as high-risk for major abdominal surgery because of a lack of functional reserve and associated medical comorbidities. The goal of this study was to compare the cost of care and short-term outcomes of elderly and nonelderly patients undergoing laparoscopic colectomy. Our hypothesis was that elderly patients managed with laparoscopic colorectal surgery and an enhanced recovery protocol (ERP) can realize the same benefits of lower hospital length of stay (LOS) without increasing hospital costs or readmission rates.

METHODS

Review of a prospective database identified all patients that underwent an elective laparoscopic colectomy from 2009 to 2012. Patients were stratified into elderly (≥70 years old) and nonelderly (<70 years old) cohorts. The main outcome measures were discharge disposition, hospital costs, hospital LOS, and 30-day readmission rates between the laparoscopic and open groups.

RESULTS

A total of 302 nonelderly (66%) and 153 elderly (34%) patients were included in the analysis. The elderly cohort had significantly higher comorbidities than the nonelderly group. There were no mortalities. Operative variables (procedure time, blood loss, and intraoperative complications) were similar. At discharge, significantly more elderly patients required temporary nursing or home care. There were no significant differences in short-term outcomes of LOS, 30-day readmission rates, or costs for the episode of care between the two groups.

CONCLUSIONS

Combining laparoscopic colectomy with an ERP is cost-effective and results in similar short-term outcomes for the elderly and nonelderly patients. Despite higher comorbidities, elderly patients realized the same benefits of shorter LOS with similar hospital costs and readmission rates.

Pitfalls of laparoscopic colorectal surgery and how to avoid them

SUMMARY Laparoscopic surgery is commonly used for colorectal diseases. Recently, laparoscopy for colorectal carcinoma has increased in use, especially by colorectal surgeons. Laparoscopy is associated with potential pitfalls that pose challenges to the surgeon and team. The identification and management of these pitfalls may not directly parallel those during an open approach. As such, it is essential for the surgeon to have a good working knowledge of how to avoid potential problems and how to best manage them when they do occur. This review highlights common pitfalls of laparoscopic colorectal surgery, as well as offering practical approaches to their management. Technical, patient and surgeon factors are all discussed.
