Laparoscopic resection for colorectal cancer improves short-term outcomes in very elderly colorectal cancer patients

Effect of screening colonoscopy frequency on colorectal cancer mortality in patients with a family history of colorectal cancer

BACKGROUND

Colorectal cancer is a common malignant tumor in China, and its incidence in the elderly is increasing annually. Inflammatory bowel disease is a group of chronic non-specific intestinal inflammatory diseases, including ulcerative colitis and Crohn's disease.

AIM

To assess the effect of screening colonoscopy frequency on colorectal cancer mortality.

METHODS

We included the clinicopathological and follow-up data of patients with colorectal cancer who underwent laparoscopic colectomy or open colectomy at our Gastrointestinal Department between January 2019 and December 2022. Surgical indicators, oncological indicators, and survival rates were compared between the groups. The results of 104 patients who met the above criteria were extracted from the database (laparoscopic colectomy group = 63, open colectomy group = 41), and there were no statistically significant differences in the baseline data or follow-up time between the two groups.

RESULTS

Intraoperative blood loss, time to first ambulation, and time to first fluid intake were significantly lower in the laparoscopic colectomy group than in the open colectomy group. The differences in overall mortality, tumor-related mortality, and recurrence rates between the two groups were not statistically significant, and survival analysis showed that the differences in the cumulative overall survival, tumor-related survival, and cumulative recurrence-free rates between the two groups were not statistically significant.

CONCLUSION

In elderly patients with colorectal cancer, laparoscopic colectomy has better short-term outcomes than open colectomy, and laparoscopic colectomy has superior long-term survival outcomes compared with open colectomy.

Comparison of short-term outcomes and survival between minimally invasive colectomy and open colectomy in patients 80 years of age and older

We investigated the short- and long-term outcomes of patients 80 years of age and older with colon cancer who underwent robotic colectomy versus laparoscopic colectomy. Data for patients treated at a comprehensive cancer center between January 2006 and November 2018 were collected retrospectively. Outcomes from minimally invasive laparoscopic or robotic colectomy were compared. Survival was analyzed by the Kaplan-Meier method with significance evaluated by the log-rank test. The laparoscopic (n = 104) and the robotic (n = 75) colectomy groups did not differ across baseline characteristics. Patients who underwent a robotic colectomy had a shorter median length of hospital stay (5 versus 6 days; p < 0.001) and underwent fewer conversions to open surgery (3% versus 17%; p = 0.002) compared to the laparoscopic cohort. The groups did not differ in postoperative complication rates, overall survival or disease-free survival. Elderly patients undergoing robotic colectomy for colon cancer have a shorter hospital stay and lower rates of conversion without compromise to oncologic outcomes.

Assessing and managing frailty in emergency laparotomy: a WSES position paper

Many countries are facing an aging population. As people live longer, surgeons face the prospect of operating on increasingly older patients. Traditional teaching is that with older age, these patients face an increased risk of mortality and morbidity, even to a level deemed too prohibitive for surgery. However, this is not always true. An active 90-year-old patient can be much fitter than an overweight, sedentary 65-year-old patient with comorbidities. Recent literature shows that frailty-an age-related cumulative decline in multiple physiological systems, is therefore a better predictor of mortality and morbidity than chronological age alone. Despite recognition of frailty as an important tool in identifying vulnerable surgical patients, many surgeons still shun objective tools. The aim of this position paper was to perform a review of the existing literature and to provide recommendations on emergency laparotomy and in frail patients. This position paper was reviewed by an international expert panel composed of 37 experts who were asked to critically revise the manuscript and position statements. The position paper was conducted according to the WSES methodology. We shall present the derived statements upon which a consensus was reached, specifying the quality of the supporting evidence and suggesting future research directions.

Factors affecting the post-operative outcomes in patients aged over 80 following colorectal cancer surgery

PURPOSE

In 2019, in Australia, there were 500,000 people aged 85 and over. Traditionally, clinicians have adopted the view that surgery is not desirable in this cohort due to increasing perioperative risk, perceived minimal clinical benefit, and shortened life expectancy. This cohort study is aimed at investigating postoperative outcomes from elective and non-elective colorectal cancer surgery in patients aged 80 and over.

METHODS

A retrospective analysis was conducted on patients from 2010 to 2020 on a prospectively maintained colorectal database. Patients aged over 80 who underwent surgical resection for colorectal cancer were reviewed. Oncological characteristics, short-term outcomes, overall survival, and relapse-free survival rates were analysed.

RESULTS

A total of 832 patients were identified from the database. Females comprised 55% of patients aged 80 and above. The median age was 84 for octogenarians and 92 for nonagenarians. Most patients were ASA 2 (212) or ASA 3 (501). ASA 3 and 4 and stage III pathology were associated with higher postoperative complications. Fifty percent of over 80 s and 37% of over 90 s were surgically discharged to their own home. Overall survival at 30, 180, and 360 days and 5 years was 98.1%, 93.1%, 87.2%, and 57.2% for the over 80 s and 98.1%, 88.9%, 74.9%, and 24.4% for the over 90 s.

CONCLUSION

Our results demonstrate that surgical treatment of older patients is safe with acceptable short-, medium-, and long-term survival. Nonetheless, efforts are needed to reduce the rates of complications in older patients, including utilisation of multi-disciplinary teams to assess the optimal treatment strategy and postoperative care.

Advantage of laparoscopy surgery for elderly colorectal cancer patients without compromising oncologic outcome

Background

Laparoscopic surgery has achieved significant results in elderly patients with colorectal cancer (CRC). In this study, we compared the short-term and long-term outcomes of open surgery and laparoscopic surgery in patients with CRC aged above 75 years at a single tertiary medical center.

Methods

We analyzed 967 patients who underwent curative resection for primary colorectal adenocarcinoma without distant metastasis between January 2009 and December 2015, in a single institution. Of the enrolled patients, 305 underwent laparoscopic surgery, and 662 received open laparotomy surgery.

Results

Compared to the patients who underwent open surgery, those who received laparoscopic surgery had significantly shorter postoperative stay (10.3 vs. 13.5 days p < 0.001) and similar postoperative morbidity (p = 0.354) and mortality (p = 0.082). In the laparoscopy cohort, six of 305 patients were converted to open surgery and one died. The long-term overall survival, cancer-specific survival, and recurrence rate were similar between both cohorts in each stage.

Conclusions

Laparoscopic surgery is suitable for elderly patients owing to shorter postoperative stay, similar long-term outcomes with open surgery, and acceptable low conversion rates. For long-term overall and oncological outcomes, the results of laparoscopic surgery were similar to that of open surgery in each TNM stage.

Long-term results of a randomized study comparing open surgery and laparoscopic surgery in elderly colorectal cancer patients (Eld Lap study)

BACKGROUND

We reported favorable short-term results of laparoscopic surgery in a randomized study comparing open and laparoscopic surgery for elderly patients with colorectal cancer (CRC). The purpose of this study is to clarify the long-term outcomes of the laparoscopic surgery for elderly patients with CRC.

METHODS

The inclusion criteria were ≥ 75 years, adenocarcinoma, ≤ T4a, M0 and elective surgery. The patients were randomly allocated to open or laparoscopic surgery according to the tumor location. The survival rates, recurrence and reasons for death were compared.

RESULT

One hundred patients (right colon 43, left colon 28, rectum 29) were included in each group. Eight patients who underwent open surgery and 2 patients who underwent laparoscopic surgery were excluded from the analysis because of metastatic diseases and other malignancies found during the operations. One hundred ninety patients (98 open, 98 laparoscopic) were analyzed. There was no difference in the backgrounds excluding more patients with vascular invasion in the laparoscopic rectal cancer. There were no differences in the 5-year overall survival rate (open vs. laparoscopic; 78.9% vs. 82.1%, p = 0.638), 5-year disease-free survival rate (70.5% vs. 62.8%, p = 0.276), 5-year recurrence-free survival rate (76.1% vs. 72.1%, p = 0.419), or 5-year cancer-specific survival rate (86.1% vs. 80.5%, p = 0.208). No differences in survival were detected in the analyses of stage and tumor location. There was no significant difference in the overall recurrence rate or recurrence site. However, distant lymph node metastases and local recurrences were more common after laparoscopic surgery than after open surgery. There was no difference in the cause of death. More than half of the patients died from other diseases in both groups (57.9% vs. 52.6%, p = 0.765).

CONCLUSION

Laparoscopic surgery showed similar long-term results compared to open surgery in elderly patients with CRC. Laparoscopic surgery is an effective surgical procedure for elderly patients with CRC.

Surgical oncology in patients aged 80 years and older is associated with increased postoperative morbidity and mortality: A systematic review and meta-analysis of literature over 25 years

BACKGROUND

The study aim is to analyze the evolution over the last 25 years of the results reported after abdominal oncological surgery in patients aged 80 years of age and older. The primary endpoint was morbidity and mortality in this group of patients; the secondary endpoint was overall survival.

METHODS

A systematic search strategy was used to browse through Medline/PubMed, EMBASE, Scopus, ClinicalTrials.gov, Cochrane Database of Systematic Reviews, and Cochrane Central Register of Controlled Trials using a combination of standardized index terms. Studies published between 1997 and 2017 were selected. Only those studies that showed morbidity and mortality after digestive and hepatobiliary tract oncological surgery in individuals aged 80 years and older were included. The PROSPERO registration number is CRD42018087921. PRISMA and MOOSE guidelines were applied.

RESULTS

A total of 79 studies were included, categorized by origin of malignancy: esophageal (7), stomach (26), liver (4), pancreas (19), and colorectal (23). Compared with the non-elderly group, the elderly group had similar esophageal morbidity with higher mortality (RR 2.51, 1.50 to 4.21; P = 0.0005); higher gastric morbidity (RR 1.25, 1.09 to 1.43; P = 0.001), and mortality (RR 2.51, 1.81 to 3.49; P = 0.0001); similar liver morbidity and mortality; higher pancreatic morbidity (RR 1.17, 1.03 to 1.33; P = 0.02) and mortality (RR 2.37, 1.86 to 3.03; P < 0.00001); and similar colorectal morbidity with higher mortality (RR 4.44, 1.91 to 10.32; P = 0.005).

CONCLUSION

Oncological surgery of most abdominal visceral tumors is associated with increased morbidity and mortality in patients older than 80 years.

The dark side of laparoscopic surgery for colorectal cancer patients aged 75 years or older

PURPOSE

The rate of postoperative morbidity and mortality is reportedly high in patients aged ≥ 75 years with colorectal cancer (CRC). In such patients, a comparison of the short-term outcome between open method and laparoscopy has not been clearly defined in Taiwan. We aimed to compare postoperative morbidity and mortality parameters after open method and laparoscopy in CRC patients aged ≥ 75 years.

METHODS

We retrospectively analyzed patients who underwent surgery for CRC from February 2009 to September 2015 at the Linkou Chang Gung Memorial Hospital in Taiwan and analyzed their clinicopathological factors. Postoperative morbidity and mortality were analyzed for evaluating if laparoscopic surgery offers more favorable outcomes than open surgery in the elderly.

RESULTS

A total of 1133 patients were enrolled and analyzed in this study; they were divided into two groups (open method vs. laparoscopy = 797 vs. 336). The anastomotic leakage rate was significantly higher in the laparoscopy group than in the open method group (3.3 vs. 0.9%, p = 0.003). Overall postoperative morbidity and mortality rates showed no significant difference between these two groups. Postoperative hospital stay was significantly shorter in the laparoscopy group than in the open method group (10.4 ± 8.7 vs. 13.8 ± 13.5 days, p < 0.001).

CONCLUSIONS

Our results suggest that laparoscopy in patients aged ≥ 75 years with CRC had higher anastomosis leakage rate compared with open surgery but is acceptable and offers the benefit of a shorter hospital stay over open surgery.

Feasibility and Safety of Laparoscopic Right Colectomy in Oldest-Old Patients with Colon Cancer: Results of the CLIMHET Study Group

BACKGROUND

Laparoscopy for colorectal cancer treatment is widely accepted. However, there is no consensus as to whether or not laparoscopy can be considered the preferred treatment strategy in octogenarian and nonagenarian patients with colon cancer. The aim of this study was to compare operative and postoperative outcomes of laparoscopic right colectomy between oldest-old (≥80 years) and younger (<80 years) patients with colon cancer.

METHODS

The study population was sampled from the CLIMHET Study Group cohort. Between January 2005 and December 2015, data were retrieved for all patients who had undergone elective laparoscopic right colectomy for colon cancer in five University Hospital centers in France (CHU of Clermont-Ferrand, Hôpital Civil of Strasbourg-IRCAD, Hôpital Henri-Mondor of Créteil, Hôpital Européen Georges Pompidou of Paris, and CHRU of Tours).

RESULTS

Overall, 473 cancer patients were selected and analyzed. There were 156 oldest-old patients (median age: 84.1 years, range: 80-96) and 317 younger patients (median age: 67 years, range: 25-79). After adjusting based on propensity score on gender, obesity, American Society of Anesthesiologists score, smoking, arteriopathy, coronaropathy, comorbidity, and American Joint Committee on Cancer staging, no significant difference was found in operative and postoperative outcomes, except for time to resume a regular diet (3.6 days versus 3.0 days, P = .008) and length of hospital stay (12.1 days versus 9.1 days, P = .03), which were longer for oldest-old patients. Overall and disease-free survival rates were also equivalent between groups.

CONCLUSION

These findings support that laparoscopic right colectomy can be safely performed in cancer patients aged 80 and older, and its outcomes are similar in oldest-old and younger patients.

Endometrial Cancer: Is This a New Disease?

The incidence of endometrial cancer is increasing, and the age of onset is younger than in prior years. Although endometrial cancer still occurs more commonly in older women, for whom the mortality rate is increasing, it also is being diagnosed in younger and younger women. The underlying cause of the increase in incidence is the epidemic of obesity and the resulting hyperinsulinemia. Conservative treatment may be indicated for younger women who wish to retain their fertility. Lifestyle modifications such as diet and exercise can modulate the risk of developing endometrial cancer as well as prevent recurrence and other comorbidities associated with obesity.

Colorectal Cancer Surgery in the Very Elderly: Nonagenarians

BACKGROUND

Surgery in the very elderly is a topic that has not been well studied, despite the steady rise in this population. With the rise in this population, there is now discussion on the safety of surgery in this cohort for colorectal cancer.

OBJECTIVE

The purpose of this study was to investigate elective and nonelective colorectal cancer surgery outcomes in patients aged ≥90 years at both private and public hospitals in Melbourne, Victoria, Australia.

DESIGN

This was a retrospective analysis of patients aged ≥90 years who were included in the prospectively maintained Cabrini Monash University Department of Surgery colorectal neoplasia database for patients entered between January 2010 and February 2015. Comorbidity, ASA score, acuity of surgery, treatment, mortality, morbidity, and survival were analyzed.

SETTINGS

This study was conducted in a tertiary referral hospital.

PATIENTS

A total of 48 patients were identified from the database. The majority of these patients were women (58.0%), ASA score III to IV (91.7%), and treated in an elective setting (79.2%). The median age was 91.8 years.

MAIN OUTCOME MEASURES

We measured 30-day mortality, 180-day mortality, and perioperative morbidity.

RESULTS

Thirty-day mortality rate was 2.1%. The 180-day mortality rate was 10.4%. A total of 29.2% of patients had a perioperative complication. Median follow-up was 21 months (range, 13-54 months). In 180-day mortality, minimally invasive surgery was associated with a lower mortality rate vs open surgery (p = 0.043). Perioperative complications were associated with nonelective surgery (p = 0.045), open surgery procedures (p = 0.014), and higher stages of disease (p = 0.014). A total of 81.3% of patients were able to return home after surgery.

LIMITATIONS

This was a retrospective study with the usual limitations; however, these have been minimized with the use of a high-quality, prospective data collection database. The median follow-up was 21 months.

CONCLUSIONS

Colorectal surgery was generally safe for nonagenarians in this study. This study demonstrates that excellent outcomes can be achieved in a selected group. Additional prospective studies with larger numbers and 5-year follow-up are recommended.

Dexmedetomidine versus Magnesium Sulfate as Adjunct during Anesthesia for Laparoscopic Colectomy

Objectives. To compare dexmedetomidine versus magnesium during laparoscopic colectomy. Patients and Methods. 51 patients were randomly allocated into 3 groups: group C (control) received saline infusion, group D dexmedetomidine 1 g/kg and then 0.4 g/kg/hr, and group M MgSO₄ 2 g and then 15 g/kg/min. Intraoperative hemodynamics were measured before and 1 min after intubation (T1 and T2), before and 5 min after peritoneal insufflation (T3 and T4), before and 5 min after 30° Trendelenburg position (T5 and T6), 5 min after resuming flat position (T7), 5 min after peritoneal deflations (T8), after extubation (T9), and at time of admission to PACU (T10). Recovery time and degree of sedation were assessed. Results. HR and MAP were significantly higher in T2, T4, and T6 compared to T1, T3, and T5, respectively, in all groups with lower measurements in groups D and M compared to group C. Mean of collective measurements was significantly higher in group C. Recovery time and sedation score were significantly higher in groups D and M. Time to Aldrete score of ≥9 was significantly longer in groups D and M. Conclusion. Both drugs ameliorate the pressor responses during LC with a nonsignificant difference. This study is registered with PACTR201602001481308.

Is laparoscopic surgery really effective for the treatment of colon and rectal cancer in very elderly over 80 years old? A prospective multicentric case-control assessment

BACKGROUND

To evaluate the effectiveness of laparoscopic surgery (LCS) for colon and rectal cancer in the very elderly over 80 years old.

METHODS

We performed a prospective multicentric analysis comparing patients over 80 years (Group A) and patients between 60 and 69 years (Group B) undergoing LCS for cancer from January 2008 to December 2013. Colon and rectal cancers were analyzed separately. Comorbidity and complications were classified using the Charlson comorbidity index (CCI) and the Clavien-Dindo system, respectively. Oncological parameters included tumor-free margins, number of lymph nodes harvested and circumferential resection margin.

RESULTS

Group A included 96 and 33 patients, and Group B 220 and 82 for colon and rectal cancers, respectively. Groups were similar except for ASA score and CCI, as expected. There was no significant difference in operative time [colon; rectum] (180[IQR 150-200] vs 180[150-210] min; NS-180[160-210] vs 180[165-240] min; NS), estimated blood loss (50[25-75] vs 50[25-120] mL; NS-50[0-150] vs 50[25-108.7] mL; NS) and conversion rate (2.1 vs 2.7 %; NS-3.0 vs 2.4 %; NS). Timing of first stool (3[2-3.25] vs 3[2-5] dd; NS-3[2-4] vs 3[2-5] dd; NS), length of stay (7[6-8] vs 7[6-8] dd; NS-8[8-9] vs 8[7-9] dd; NS) and readmission rate (1.0 vs 0.45 %; NS-6.1 vs 1.2 %; NS) were similar. Tumor-free margins were appropriate, and positivity of CRM is poor (6.1 vs 4.9; NS). We did not record significant differences in complications rate (47.9 vs 43.6 %; NS-63.6 vs 52.4 %; NS).

CONCLUSIONS

Laparoscopic surgery is effective for the treatment of colorectal cancer even in the very elderly. Age is not a risk factor or a limitation for LCS.

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.

Laparoscopic colorectal resection versus open colorectal resection in octogenarians: a systematic review and meta-analysis of safety and efficacy

Octogenarians are more often viewed as high-risk surgical candidates. This increased risk is attributed to an age-related decline in physical function and reserve capacity coupled with the presence of various underlying diseases. There are no current guidelines or consensus on the optimal treatment strategy for this cohort of complex patients. The aim of this systematic review and meta-analysis was to compare the efficacy and safety of laparoscopic colorectal resection versus open colorectal resection in octogenarians. The meta-analysis was conducted following all aspects of the Cochrane Handbook for Systematic Reviews and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. A systematic literature review was carried out using the following databases: MEDLINE, Embase, PubMed, the Cochrane Library, Google Scholar and OVID. Only studies comparing outcome of laparoscopic and open colorectal resections in the elderly population (≥80 years) were selected. The data collected included the patient demographics, interventions, observed outcome and sources of bias. When performing the statistical analysis, we used the odds ratio for categorical variables and the weighted mean difference for continuous variables. The results of this systematic review and pooled analysis demonstrated the safety and potential benefits of laparoscopic colorectal resection in octogenarians. LC can reduce the length of hospital stay, intraoperative blood loss, time to return of normal bowel function, and incidence of postoperative pneumonia, wound infection, and postoperative ileus.

Colorectal cancer screening and surveillance in the elderly: updates and controversies

Colorectal cancer is common worldwide, and the elderly are disproportionately affected. Increasing age is a risk factor for the development of precancerous adenomas and colorectal cancer, thus raising the issue of screening and surveillance in older patients. Elderly patients are a diverse and heterogeneous group, and special considerations such as comorbid medical conditions, functional status and cognitive ability play a role in deciding on the utility of screening and surveillance. Colorectal cancer screening can be beneficial to patients, but at certain ages and under some circumstances the harm of screening outweighs the benefits. Increasing adverse events, poorer bowel preparation and more incomplete examinations are observed in older patients undergoing colonoscopy for diagnostic, screening and surveillance purposes. Decisions regarding screening, surveillance and treatment for colorectal cancer require a multidisciplinary approach that accounts not only for the patient’s age but also for their overall health, preferences and functional status. This review provides an update and examines the challenges surrounding colorectal cancer diagnosis, screening, and treatment in the elderly.

Laparoscopic Colorectal Resection in Octogenarian Patients: Is it Safe? A Systematic Review and Meta-Analysis

The population older than 80 years has been increasing. A significant proportion of colorectal diseases that require colorectal resection occur in very elderly patients. However, the benefits of laparoscopy remain controversial in octogenarians. A systematic review and meta-analysis of observational study was performed to compare clinical outcomes between laparoscopic versus open colorectal resection in octogenarians.The PubMed, EMBASE, Ovid, Web of Science, and Cochrane databases from the years 1990 to 2015 were searched for studies that compare surgical outcomes between laparoscopic and open colorectal resection in octogenarians (≥80 years old).Seven eligible studies including 528 laparoscopic and 484 open colorectal resections were identified. Laparoscopic approach was associated with lower rate of mortality (odds ratio [OR] 0.48, P = 0.03), overall complications (OR 0.54, P < 0.001), and prolonged ileus (OR 0.56, P = 0.009), quicker bowel function return (standardized mean difference [SMD] -0.50, P< 0.001), and shorter length of hospital stay (SMD -0.47, P = 0.007). No differences were found in anastomotic leak (OR 1.16, P = 0.72), respiratory complication (OR 0.60, P = 0.07), and reoperation (OR 0.85, P = 0.69).Laparoscopic colorectal resection is as safe as open approach, and the short-term outcomes appear to be more favorable in octogenarians.

Do the advantages of a minimally invasive approach remain in complex colorectal procedures? A nationwide comparison

BACKGROUND

Since the introduction of laparoscopic colectomy, experience and technology continue to improve. Although accepted for many colorectal conditions, its use and outcomes in complex procedures are less understood.

OBJECTIVE

The purpose of this work was to compare the perioperative outcomes of laparoscopic transverse colectomy and total abdominal colectomy (study group) with an open approach (comparative group) and the more established laparoscopic right, left, and sigmoid colectomies (control group).

DESIGN

This was a retrospective review of the Nationwide Inpatient Sample (2008-2011) of all patients undergoing elective right, left, sigmoid, total, or transverse colectomy as identified by International Classification of Diseases, Ninth Revision, Clinical Modification procedure codes. Risk-adjusted 30-day outcomes were assessed using regression modeling accounting for patient characteristics, comorbidities, and surgical procedures.

SETTINGS

The study included a national sample from a population database.

PATIENTS

There were 45,771 admissions: 2946 in the study group, 36,949 in the control group, and 5876 in the open comparative group.

MAIN OUTCOME MEASURES

Mortality was the primary outcome. Secondary outcomes included in-hospital complications, length of stay, and hospital charges.

RESULTS

The patients were predominantly white (73%), had private insurance (64%), and underwent surgery at urban centers (92%). Mortality was similar between the study and control groups (0.42% vs 0.51%; p = 0.52), with a higher complication rate in the study group (19% vs 14%; p < 0.01). The study group was also associated with a lower mortality rate compared with the open group (0.51% vs 2.20%; p < 0.01), which remained consistent after adjusting for covariates (OR, 0.38 [95% CI, 0.20-0.71]; p < 0.01). The study group had fewer complications overall compared with the open group (19% vs 27%; p < 0.01) and a shorter median length of stay (4.6 vs 6.3 days; p < 0.01).

LIMITATIONS

This was a retrospective study using an administrative database.

CONCLUSIONS

A laparoscopic approach for total abdominal and transverse colectomies has similar mortality rates and slightly higher complications than the more established laparoscopic colectomy procedures and improved perioperative outcomes when compared with an open technique (see Video, Supplemental Digital Content 1, http://links.lww.com/DCR/A178).

Colorectal cancer of the elderly

OPINION STATEMENT

Colorectal cancer (CRC) disproportionately affects the elderly. Older age is a strong risk factor for both the development of precancerous adenomas and CRC, thus raising the issue of screening and surveillance in older patients. However, screening and surveillance decisions in the elderly can be complex and challenging. Elderly patients are a diverse and heterogeneous group and special considerations such as co-morbid medical conditions, functional status, and cognitive ability play a role in one's decisions regarding the utility of screening and surveillance. Such considerations also play a role in factors related to screening modalities, such as colonoscopy, as well as CRC treatment options and regimens. This review addresses many of the unique factors associated with CRC of the elderly and critically examines many of the controversies and challenges surrounding CRC in older patients.
