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

Laparoscopic and robotic surgery for colorectal cancer in older patients: a systematic review and meta-analysis

INTRODUCTION

As life expectancy has been increasing, older patients are becoming more central to the healthcare system, leading to more intensive care use and longer hospital stays. Nevertheless, advancements in minimally invasive surgical techniques offer safe and effective options for older patients with colorectal diseases. This study aims to provide comprehensive evidence on the role of minimally invasive surgery in treating colorectal diseases in older patients.

MATERIAL AND METHODS

All articles directly compared the minimally invasive approach with open surgery in patients aged ≥65 years. The present metanalysis took 30-day complications as primary outcomes. Length of hospital stay, readmission, and 30-day mortality were also assessed, as secondary outcomes. Further subgroup analyses were carried out based on surgery setting, lesion features, and location.

RESULTS

After searching the main databases, 84 articles were included. Evaluation of 30-day complications rate, length of hospital stay, and 30-day mortality significantly favored minimally invasive approaches. The outcome readmission did not show any significant difference.

CONCLUSIONS

The current metanalysis demonstrates clear advantages of minimally invasive techniques over open surgery in colorectal procedures for older patients, particularly in reducing complications, mortality, and hospitalization. This suggests that prioritizing these techniques, based on available expertise and facilities, could improve outcomes and quality of care for older patients undergoing colorectal surgery.

EAES/SAGES evidence-based recommendations and expert consensus on optimization of perioperative care in older adults

BACKGROUND

As the population ages, more older adults are presenting for surgery. Age-related declines in physiological reserve and functional capacity can result in frailty and poor outcomes after surgery. Hence, optimizing perioperative care in older patients is imperative. Enhanced Recovery After Surgery (ERAS) pathways and Minimally Invasive Surgery (MIS) may influence surgical outcomes, but current use and impact on older adults patients is unknown. The aim of this study was to provide evidence-based recommendations on perioperative care of older adults undergoing major abdominal surgery.

METHODS

Expert consensus determined working definitions for key terms and metrics related to perioperative care. A systematic literature review and meta-analysis was performed using the PubMed, Embase, Cochrane Library, and Clinicaltrials.gov databases for 24 pre-defined key questions in the topic areas of prehabilitation, MIS, and ERAS in major abdominal surgery (colorectal, upper gastrointestinal (UGI), Hernia, and hepatopancreatic biliary (HPB)) to generate evidence-based recommendations following the GRADE methodology.

RESULT

Older adults were defined as 65 years and older. Over 20,000 articles were initially retrieved from search parameters. Evidence synthesis was performed across the three topic areas from 172 studies, with meta-analyses conducted for MIS and ERAS topics. The use of MIS and ERAS was recommended for older adult patients particularly when undergoing colorectal surgery. Expert opinion recommended prehabilitation, cessation of smoking and alcohol, and correction of anemia in all colorectal, UGI, Hernia, and HPB procedures in older adults. All recommendations were conditional, with low to very low certainty of evidence, with the exception of ERAS program in colorectal surgery.

CONCLUSIONS

MIS and ERAS are recommended in older adults undergoing major abdominal surgery, with evidence supporting use in colorectal surgery. Though expert opinion supported prehabilitation, there is insufficient evidence supporting use. This work has identified evidence gaps for further studies to optimize older adults undergoing major abdominal surgery.

Longitudinal analysis of long-term outcomes of colorectal cancer after laparotomy and laparoscopic surgery: The Shizuoka study

BACKGROUND

Long-term cancer prognosis after initial surgical procedures is an unlikely endpoint for clinical trials. Medical claim databases may aid in addressing this issue regardless of limited information on disease and patient background. However, the long-term prognosis (especially regarding long-term care needs) following surgical procedures remains unclear. This study aimed to assess whether long-term outcomes, such as the exacerbation of long-term care needs and mortality, differ with surgical methods.

METHODS

Using a longitudinal study with linkage between medical claim and long-term care database, patients with primary colorectal cancer who underwent initial colonoscopies were identified through anonymized data in Japan (Shizuoka Kokuho Database, 2012-2018). Odds ratios (ORs) for long-term outcomes (long-term care needs and all-cause mortality during a 6.5-year follow-up period) were analyzed using logistic regression to compare laparoscopy and endoscopic surgery to laparotomy.

RESULTS

Overall, 3,744 primary colorectal cancer cases (822 laparotomies, 705 laparoscopies, and 2,217 endoscopic surgeries) were included. Compared to the laparotomy group, the crude OR for exacerbation of long-term care needs in the laparoscopic surgery group was 0.376 (95% confidence interval, 0.227, 0.624), while the OR for all-cause mortality was 0.22 (0.329, 0.532).

CONCLUSION

This is the first study to analyze long-term prognosis after surgery for patients with colorectal cancer to combine medical and long-term needs data. As the national health insurance claim database rarely includes information on cancer stage and comorbidities, better prognosis on endoscopic surgery may need careful interpretation. Therefore, laparoscopy has superior outcomes in terms of long-term care needs and mortality compared to those of laparotomy.

Outcomes of Laparoscopic Surgery in Very Elderly Patients with Colorectal Cancer: A Survival Analysis and Comparative Study

(1) Background: Colorectal cancer (CRC) is a global health concern, particularly among the elderly population. This study aimed to assess the impact of laparoscopic surgery on CRC patients aged ≥80 years. (2) Methods: We conducted a retrospective analysis of prospectively collected data from consecutive CRC patients who underwent surgery at our institution between July 2018 and July 2023. The patients were categorized into three groups: those aged over 80 who underwent laparoscopic surgery (Group A), those aged over 80 who underwent open surgery (Group B), and those under 80 who underwent laparoscopic surgery (Group C). We examined various clinical and surgical parameters, including demographic data, medical history, surgical outcomes, and survival. (3) Results: Group A (N = 113) had shorter hospital stays than Group B (N = 23; p = 0.042), with no significant differences in complications or 30-day outcomes. Compared to Group C (N = 269), Group A had higher comorbidity indices (p < 0.001), more emergency admissions, anemia, low hemoglobin levels, colonic obstruction (p < 0.001), longer hospital stays (p < 0.001), and more medical complications (p = 0.003). Laparotomic conversion was associated with obstructive neoplasms (p < 0.001), and medical complications with ASA scores (p < 0.001). Both the medical and surgical complications predicted adverse 30-day outcomes (p = 0.007 and p < 0.001). Survival analysis revealed superior overall survival (OS) in Group A vs. Group B (p < 0.0001) and inferior OS vs. Group C (p < 0.0001). After a landmark analysis, the OS for patients aged 80 or older and those under 80 appeared to be similar (HR 2.55 [0.75-8.72], p = 0.136). (4) Conclusions: Laparoscopic surgery in very elderly CRC patients shows comparable oncological outcomes and surgical complications to younger populations. Survival benefits are influenced by age, comorbidities, and medical complications. Further prospective multicenter studies are needed in order to validate these findings.

Laparoscopic versus open surgical management in elderly patients with rectal cancer aged 70 and older

Background

This retrospective study aimed to compare the short- and long-term surgical outcomes of laparoscopic surgery versus open surgery in elderly patients with rectal cancer.

Patients and Methods

Elderly patients (≥70 years old) with rectal cancer who received radical surgery were retrospectively analysed. Patients were matched (1:1 ratio) using propensity score matching (PSM), with age, sex, body mass index, American Society of Anesthesiologists score and tumour-node-metastasis staging included as covariates. Baseline characteristics, post-operative complications, short- and long-term surgical outcomes and overall survival (OS) were compared between the two matched groups.

Results

Sixty-one pairs were selected after PSM. Patients with laparoscopic surgery had a longer duration of operation time, lower estimated blood loss, shorter duration of post-operative analgesics administered, time to first flatus, time to first oral diet and post-operative hospitalisation stay than those observed in patients with open surgery (All P < 0.05). The incidence of post-operative complications in the open surgery group was numerically higher than that occurred in the laparoscopic surgery group (30.6% vs. 17.7%). Median OS was 67.0 months (95% confidence interval [CI], 62.2-71.8) in the laparoscopic surgery group and 65.0 months (95% CI, 59.9-70.1) in the open surgery group, however, Kaplan-Meier curves indicated that no significant differences in OS (Log-rank test, P = 0.535) were noted between the two matched groups.

Conclusions

Compared with the open surgery, laparoscopic surgery had the advantages of less trauma and faster recovery, and provided similar long-term prognostic outcome in elderly patients with rectal cancer.

Comparison of outcomes of open and laparoscopic appendectomy: A retrospective cohort study

Background

Open appendectomy has been the conventional choice of treatment for acute appendicitis. However, nowadays laparoscopic approach is emerging for the benefits it provides, like lesser postoperative pain and lesser duration of hospital stay, but at the cost of higher expenses and longer operative duration.

Methods

A retrospective cohort study was done at Shree Birendra Hospital from January 2018 to December 2021, with a total study population of 450 participants (300 in open appendectomy and 150 in laparoscopic appendectomy). Preoperative. Intraoperative and postoperative parameters were compared and analyzed between two groups using SPSS-25.

Results

The mean age was 26.72 ± 9.70 in the open appendectomy (OA) and years 23.89 ± 6.32 in the laparoscopic appendectomy (LA) group. (p = 0.010) There was a significant difference between the mean operative time (46.08 ± 13.10 min in OA and 56.86 ±  11.70 min in LA, p = 0.000), length of hospital stay (1.28 ± 0.80 days in OA and 1.07 ±  0.25 days in LA, p = 0.000), course of oral analgesics (3.55 ± 0.68 days in OA and 3.00 days in LA p = 0.000) between OA groups and LA groups, while the total number of complications was less in the LA group however there was no statistically significant difference postoperative complications (p = 0.124) between the two groups in the surgical findings.

Conclusion

All in all, the laparoscopic approach is a better option for uncomplicated appendicitis due to its less postoperative pain and shorter duration of hospital stay.

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.

Is fascial closure required for a 12-mm trocar? A comparative study on trocar site hernia with long-term follow up

BACKGROUND

Despite the infrequency of trocar site hernias (TSHs), fascial closure continues to be recommended for their prevention when using a ≥ 10-mm trocar.

AIM

To identify the necessity of fascial closure for a 12-mm nonbladed trocar incision in minimally invasive colorectal surgeries.

METHODS

Between July 2010 and December 2018, all patients who underwent minimally invasive colorectal surgery at the Minimally Invasive Surgery Unit of Siriraj Hospital were retrospectively reviewed. All patients underwent cross-sectional imaging for TSH assessment. Clinicopathological characteristics were recorded. Incidence rates of TSH and postoperative results were analyzed.

RESULTS

Of the 254 patients included, 70 (111 ports) were in the fascial closure (closed) group and 184 (279 ports) were in the nonfascial closure (open) group. The median follow up duration was 43 mo. During follow up, three patients in the open group developed TSHs, whereas none in the closed group developed the condition (1.1% vs 0%, P = 0.561). All TSHs occurred in the right lower abdomen. Patients whose drains were placed through the same incision had higher rates of TSHs compared with those without the drain. The open group had a significantly shorter operative time and lower blood loss than the closed group.

CONCLUSION

Routine performance of fascial closure when using a 12-mm nonbladed trocar may not be needed. However, further prospective studies with cross-sectional imaging follow-up and larger sample size are needed to confirm this finding.

Prognosis of laparoscopic surgery for colorectal cancer in middle-aged patients

Background

The prognosis of middle-aged patients with colorectal cancer (CRC) treated by laparoscopic resection (LR) is unclear. This study aimed to evaluate the survival outcomes of LR compared with open resection (OR) for middle-aged patients with CRC.

Patients and Methods

This retrospective cohort study used the data from a database of all consecutive colorectal resections performed between January 2009 and December 2017. Propensity score matching (PSM) was performed to handle the selection bias based on age, gender, body mass index, tumour location, AJCC stage and admission year. Univariate and multivariate COX regression model was used to identify risk factors of overall survival (OS) and disease-free survival (DFS).

Results

After PSM, 154 patients were included in each group. Compared with the OR group in the total cohort, there were better survival outcomes in the LR group for 5-year OS and 5-year DFS (both P < 0.001). These differences were observed for Stage II and III diseases and for all CRC, irrespective of location. The multivariate analysis showed that tumour ≥5 cm (hazard ratio [HR] = 1.750, 95% confidence interval [CI]: 1.026-2.986, P = 0.040), Stage III (HR = 14.092, 95% CI: 1.894-104.848, P = 0.010) and LR (HR = 0.300, 95% CI: 0.160-0.560, P < 0.001) were independently associated with OS. Pre-operative carcinoembryonic antigen ≥5 ng/ml (HR = 3.954, 95% CI: 1.363-11.473, P = 0.011), Stage III (HR = 6.206, 95% CI: 1.470-26.200, P = 0.013) and LR (HR = 0.341, 95% CI: 0.178-0.653, P = 0.001) were independently associated with DFS.

Conclusions

In middle-aged patients with CRC, LR achieves better survival than OR. Complications are similar, except for less blood loss and shorter post-surgical hospital stay with LR.

Decreasing Postoperative Pulmonary Complication Following Laparoscopic Surgery in Elderly Individuals with Colorectal Cancer: A Competing Risk Analysis in a Propensity Score-Weighted Cohort Study

Simple Summary

As the effect of laparoscopic surgery on elderly patients with colorectal cancer (CRC) remains unclear, this propensity score–weighted cohort study revealed that laparoscopic surgery is a favorable method for elderly patients with CRC than open surgery in terms of less pulmonary-related postoperative morbidity and mortality, less hospital stay and similar oncological outcomes.

Abstract

Advanced age is a risk factor for major abdominal surgery due to a decline in physical function and increased comorbidities. Although laparoscopic surgery provides good results in most patients with colorectal cancer (CRC), its effect on elderly patients remains unclear. This study aimed to compare the short- and long-term outcomes between open and laparoscopic surgeries in elderly patients with CRC. Total 1350 patients aged ≥75 years who underwent curative resection for stage I–III primary CRC were enrolled retrospectively and were divided into open surgery (846 patients) and laparoscopy (504 patients) groups. After propensity score weighting to balance an uneven distribution, a competing risk analysis was used to analyze the short-term and long-term outcomes. Postoperative mortality rates were lower in the laparoscopy group, especially due to pulmonary complications. Postoperative hospital stay was significantly shorter in the laparoscopy group than in the open surgery group. Overall survival, disease-free survival, and competing risk analysis showed no significant differences between the two groups. Laparoscopic surgery for elderly patients with CRC significantly decreased pulmonary-related postoperative morbidity and mortality in this large cohort study. Laparoscopic surgery is a favorable method for elderly patients with CRC than open surgery in terms of less hospital stay and similar oncological outcomes.

Structured presurgery prehabilitation for aged patients undergoing elective surgery significantly improves surgical outcomes and reduces cost: A nonrandomized sequential comparative prospective cohort study

Background

With increasing global life expectancy, the number of major surgeries performed on aged adults invariably increases. This study aimed to examine the effectiveness of a structured prehabilitative program for aged colorectal cancer patients in improving short‐term surgical outcomes.

Methods

A prospective philanthropically sponsored Programme for Enhanced Elderly Recovery at Sengkang General Hospital (PEERS) was initiated in February 2017 for patients ≥70‐years‐old who were due to undergo elective colectomies. These patients were put through a 2‐ to 4‐week‐long program before surgery, which included geriatric assessment, nutrition supplementation, and resistance training. They were compared with patients from a similar age group before PEERS was introduced (non‐PEERS).

Results

Fifty‐eight patients, with a median age of 78.5 (70–93) years, were recruited from a single institution to undergo PEERS. Baseline characteristics between the groups were similar. There was no significant improvement of anthropometric and functional characteristics before and after PEERS. Duration of hospitalization was shorter in the PEERS group (9 vs 11 days, P = 0.01). Both groups had similar 30‐days’ morbidity rates (8.6% vs 17.4%, P = 0.26). The PEERS group had significant improvement in their median EuroQol‐5 Dimension score (0.70 presurgery to 0.80 6‐months’ postsurgery, P = 0.01). After multivariate analysis, the average duration of hospitalization in the PEERS group was 6.8 days shorter (P = 0.018; CI, 1.2–12.4) after adjusting for modality of surgery and complications. This represented a cost saving of USD$11,838.80.

Conclusion

A standardized prehabilitation program for aged adults reduced the duration of hospitalization, improved the quality of life after surgery, and reduced costs.

Robotic Colorectal Cancer Surgery. How to Reach Expertise? A Single Surgeon-Experience

The complexity associated with laparoscopic colorectal surgery requires several skills to overcome the technical difficulties related to this procedure. To overcome the technical challenges of laparoscopic surgery, a robotic approach has been introduced. Our study reports the surgical outcomes obtained by the transition from laparoscopic to robotic approach in colorectal cancer surgery to establish in which type of approach the proficiency is easier to reach. Data about the first consecutive 15 laparoscopic and the first 15 consecutive robotic cases are extracted, adopting as a comparator of proficiency the last 15 laparoscopic colorectal resections for cancer. The variables studied are operative time, number of harvested nodes, conversion rate, postoperative complications, recovery outcomes. Our analysis includes 15 patients per group. Our results show that operative time is significantly longer in the first 15 laparoscopic cases (p = 0.001). A significantly lower number of harvested nodes was retrieved in the first 15 laparoscopic cases (p = 0.003). Clavien Dindo I complication rate was higher in the first laparoscopic group, but without a significant difference among the three groups (p = 0.09). Our results show that the surgeon needed no apparent learning curve to reach their laparoscopic standards. However, further multicentric prospective studies are needed to confirm this conclusion.
