Robot-assisted surgery in elderly and very elderly population: our experience in oncologic and general surgery with literature review

Gynecologic oncology robot-assisted surgery in octogenarians: Impact of age on hospital stay

OBJECTIVE

To compare postoperative stay in octogenarians and younger patients undergoing gynecologic oncology robot-assisted surgery.

METHODS

A retrospective review of robot-assisted surgery in Gynecological Oncology division during 2019-2022. We included all consecutive cases. Octogenarians (age ≥80 years) and younger patients were investigated by univariable analysis for characteristics and outcome.

RESULTS

A total of 816 robot-assisted surgeries were performed, 426 (52.2%) endometrial cancer, 159 (19.5%) ovarian cancer, 27 (3.3%) cervical cancer, 35 (4.3%) endometrial intraepithelial neoplasia, and in 169 (20.7%) the final pathology was benign. There were 60 (7.4%) octogenarians and 756 (92.6%) younger patients. The proportion of patients with an American Society of Anesthesiology score greater than 2 was higher among octogenarians (66.7% vs 32.0%, P < 0.001). The median console time, surgical time, and total operation theater time were similar between groups (P = 0.303, P = 0.643 and P = 0.688, respectively). Conversion rate did not differ between groups (0.4% among younger patients vs 0% in octogenarians, P > 0.99). The median length of stay in the recovery room was similar in both groups (median 170 min, interquartile range [IQR] 125-225 min vs 170 min, IQR 128-240 min in octogenarians, P = 0.731). Length of hospital stay was similar in both age groups; median 1 day (IQR 1-1) among octogenarians versus 1 (0-1) in younger patients (P = 0.136).

CONCLUSION

Octogenarians undergoing robotic surgery have no increased risk of length of stay or conversion to laparotomy compared with younger patients.

Robot-assisted vs. laparoscopic right hemicolectomy in octogenarians and nonagenarians: an analysis of the US nationwide inpatient sample 2005-2018

BACKGROUND

Colorectal cancer (CRC) is a significant health concern, particularly among older adults. Outcomes between laparoscopic and robot-assisted surgeries for right-sided colon cancers in the oldest old population have yet to be evaluated despite increased use of these surgeries.

AIM

This study aimed to compare clinical outcomes after robot-assisted right hemicolectomy (RARH) versus laparoscopic right hemicolectomy (LRH) in octogenarian and nonagenarian patients.

METHODS

This population-based, retrospective and observational study analyzed the data of adults ≥ 80 years old diagnosed with right-side colon cancer who received RARH or LRH. All data were extracted from the US National Inpatient Sample (NIS) database 2005-2018. Associations between type of surgery and in-hospital outcomes were determined using univariate and multivariable logistic regression and linear regression analysis.

RESULTS

Data of 7,550 patients (representing 37,126 hospitalized patients in the U.S.) were analyzed. Mean age of the study population was 84.8 years, 61.4% were females, and 79.1% were non-smokers. After adjusting for relevant confounders, regression analysis showed that patients undergoing RARH had a significantly shorter LOS (adjusted Beta (aBeta), -0.24, 95% CI: -0.32, -0.15) but greater total hospital costs (aBeta, 26.54, 95% CI: 24.64, 28.44) than patients undergoing LRH. No significant differences in mortality, perioperative complications, and risk of unfavorable discharge were observed between the two procedures (p > 0.05). Stratified analyses by frailty status revealed consistent results.

CONCLUSIONS

RARH is associated with a significantly shorter LOS but higher total hospital costs than LRH among octogenarians and nonagenarians. Other short-term outcomes for this population are similar between the two procedures, including in-hospital mortality, perioperative complications, and unfavorable discharge. These findings also apply to frail patients.

Emergency robotic surgery: the experience of a single center and review of the literature

BACKGROUNDS

Laparoscopic surgery is widely used in abdominal emergency surgery (AES), and the possibility of extending this approach to the more recent robotic surgery (RS) arouses great interest. The slow diffusion of robotic technology mainly due to high costs and the longer RS operative time when compared to laparoscopy may represent disincentives, especially in AES. This study aims to report our experience in the use of RS in AES assessing its safety and feasibility, with particular focus on intra- and post-operative complications, conversion rate, and surgical learning curve. Our data were also compared to other experiences though an extensive literature review.

METHODS

We retrospectively analysed a single surgeon series of the last 10 years. From January 2014 to December 2023, 36 patients underwent urgent or emergency RS. The robotic devices used were Da Vinci Si (15 cases) and Xi (21 cases).

RESULTS

36 (4.3%) out of 834 robotic procedures were included in our analysis: 20 (56.56%) females. The mean age was 63 years and 30% of patients were ≥ 70 years. 2 (5.55%) procedures were performed at night. No conversions to open were reported in this series. According to the Clavien-Dindo classification, 2 (5.5%) major complications were collected. Intraoperative and 30-day mortality were 0%.

CONCLUSIONS

Our study demonstrates that RS may be a useful and reliable approach also to AES and intraoperative laparoscopic complications when performed in selected hemodynamically stable patients in very well-trained robotic centers. The technology may increase the minimally invasive use and conversion rate in emergent settings in a completely robotic or hybrid approach.

Comparison of Short-Term Outcomes after Robotic Surgery for Gastric Cancer in Elderly and Younger Patients: A Retrospective Cohort Study

Robot-assisted surgery has recently been introduced to overcome some drawbacks and technical limitations in performing laparoscopic gastrectomy. The aim of the present study was to evaluate the feasibility and safety of robotic gastrectomy in elderly patients. The study enrolled 143 patients who underwent robotic gastrectomy in a single high-volume centre. All patients were divided into two groups based on age: elderly group ≥ 75 years old (EG; n = 64) and non-elderly group < 75 years old (NEG; n = 79). Comorbidities were significantly more frequent in the EG (95.3%) than in the NEG (81%) (p = 0.011). Similarly, the percentage of ASA 3 patients was significantly higher in the EG than in the NEG (43.8% vs. 24.0%, respectively; p = 0.048). Nevertheless, the incidence of Clavien-Dindo grade III and IV complications did not differ significantly between the two groups (10.9% in the EG and 6.3% in the NEG; p = 0.852). Moreover, operative time, re-operation rate, mean number of harvested lymph nodes, 30-day mortality, and median hospital stay were similar within the two groups. Our study suggests that robotic gastrectomy can be performed safely for elderly patients. In particular, chronological age does not seem to affect either the clinical or oncological short-term outcomes after robotic gastrectomy.

Robot-assisted partial nephrectomy in younger versus older adults with renal cell carcinoma: a propensity score-matched analysis

PURPOSE

Our study aimed to compare the surgical outcomes of robot-assisted partial nephrectomy (RAPN) between younger and older patients after adjusting for their background differences. We particularly assessed RAPN outcomes and safety in older patients.

METHODS

We retrospectively evaluated 559 patients clinically diagnosed with T1 renal cell carcinoma (RCC) and treated with RAPN between 2013 and 2022 at five institutions in Japan. The patients were classified into two groups according to their age during surgery (younger group: < 75 years, older group: ≥ 75 years). Propensity score matching (PSM) was performed to adjust for the differences in the backgrounds between younger and older patients, and surgical outcomes were compared.

RESULTS

Among the 559 patients, 422 (75.5%) and 137 (24.5%) were classified into the younger and older groups, respectively; 204 and 102 patients from the younger and older groups were matched according to PSM, respectively. Subsequently, patient characteristics other than age were not significantly different between the two groups. In the matched cohort, the older group had more patients with major complications (younger, 3.0%; older, 8.8%; P = 0.045).

CONCLUSION

Surgical outcomes of RAPN in older patients with RCC were comparable with those in younger patients, although older patients experiencedsignificantly more complications than younger patients. These results suggest the need for further detailed preoperative evaluation and appropriate postoperative management in older patients receiving RAPN.

Fashioning esophagogastric anastomosis in robotic Ivor-Lewis esophagectomy: a multicenter experience

BACKGROUND

The aim of the present study is to compare outcomes of the robotic hand-sewn, linear- and circular-stapled techniques performed to create an intrathoracic esophagogastric anastomosis in patients who underwent Ivor-Lewis esophagectomy.

METHODS

Patients who underwent a planned Ivor-Lewis esophagectomy were retrospectively analysed from prospectively maintained databases. Only patients who underwent a robotic thoracic approach with the creation of an intrathoracic esophagogastric anastomosis were included in the study. Patients were divided into three groups: hand-sewn-, circular stapled-, and linear-stapled anastomosis group. Demographic information and surgery-related data were extracted. The primary outcome was the rate of anastomotic leakages (AL) in the three groups. Moreover, the rate of grade A, B and C anastomotic leakage were evaluated. In addition, patients of each group were divided in subgroups according to the characteristics of anastomotic fashioning technique.

RESULTS

Two hundred and thirty patients were enrolled in the study. No significant differences were found between the three groups about AL rate (p = 0.137). Considering the management of the AL for each of the three groups, no significant differences were found. Evaluating the correlation between AL rate and the characteristics of anastomotic fashioning technique, no significant differences were found.

CONCLUSIONS

No standardized anastomotic fashioning technique has yet been generally accepted. This study could be considered a call to perform ad hoc high-quality studies involving high-volume centers for upper gastrointestinal surgery to evaluate what is the most advantageous anastomotic technique.

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.

Robotic versus laparoscopic colectomy outcomes in colon adenocarcinoma in the elderly population: a propensity-score matched analysis of the National Cancer Database

PURPOSE

While robotic surgery is more costly and involves longer intra-operative time, it has a technical advantage over laparoscopic surgery. With our aging population, patients are being diagnosed with colon cancer at older ages. The aim of this study is to compare laparoscopic versus robotic colectomy short- and long-term outcomes in elderly patients diagnosed with colon cancer at a national level.

METHODS

This retrospective cohort study was conducted using the National Cancer Database. Subjects ≥ 80-years-old who were diagnosed with stage I to III colon adenocarcinoma and underwent a robotic or laparoscopic colectomy from 2010-2018 were included. The laparoscopic group was propensity-score matched in a 3:1 ratio to the robotic group with 9343 laparoscopic and 3116 robotic cases matched. The main outcomes evaluated were 30-day mortality, 30-day readmission rate, median survival, and length of stay.

RESULTS

There was no significant difference in the 30-day readmission rate (OR = 1.1, CI = 0.94-1.29, p = 0.23) or 30-day mortality rate (OR = 1.05, CI = 0.86-1.28, p = 0.63) between both groups. Robotic surgery was associated with higher overall survival (42 vs 44.7 months, p < 0.001) using a Kaplan-Meier survival curve. Robotic surgery had a statistically significant shorter length of stay (6.4 vs. 5.9 days, p < 0.001).

CONCLUSION

Robotic colectomies are associated with higher median survival rates and decrease in the length of hospital stay compared to laparoscopic colectomies in the elderly population.

Should Laparoscopic Complete Mesocolic Excision Be Offered to Elderly Patients to Treat Right-Sided Colon Cancer?

BACKGROUND

Despite its potential oncologic benefit, complete mesocolic excision (CME) has rarely been offered to elderly patients. The present study evaluated the effect of age on postoperative outcomes among patients undergoing laparoscopic right colectomies with CME for right-sided colon cancer (RCC).

METHODS

Data of patients undergoing laparoscopic right colectomies with CME for RCC between 2015 and 2018 were retrospectively analyzed. Selected patients were divided into two groups: the under-80 group and the over-80 group. Surgical, pathological, and oncological outcomes among the groups were compared.

RESULTS

A total of 130 patients were selected (95 in the under-80 group and 35 in the over-80 group). No difference was found between the groups in terms of postoperative outcomes, except for median length of stay and adjuvant chemotherapy received, which were in favor of the under-80 group (5 vs. 8 days, p < 0.001 and 26.3% vs. 2.9%, p = 0.003, respectively). No difference between the groups was found regarding overall survival and disease free survival. Using multivariate analysis, only the ASA score > 2 (p = 0.01) was an independent predictor of overall complications.

CONCLUSIONS

laparoscopic right colectomy with CME for RCC was safely performed in elderly patients ensuring similar oncological outcomes compared to younger patients.

Is pancreatic head surgery safe in the elderly?

BACKGROUND

During the last century, life expectancy has doubled. As a result, senior patients with cancer are more frequently referred for possible surgery. Pancreatic surgery is a complex surgery associated with significant postoperative morbidity. Surgical decision-making in the elderly population can be difficult because outcomes in the elderly are poorly defined. Our objective is to characterize differences in mortality and morbidity for pancreatic surgery in the elderly population.

METHODS

A retrospective review of all patients undergoing pancreatic head surgery in our tertiary referral center from 2015 to 2021 was conducted. Analysis was performed for the entire cohort, classifying patients into three age groups: <70 years, 70-79 years, and ≥80 years. Data from these three groups were compared, including comorbidity, oncologic outcomes and postoperative complications.

RESULTS

A total of 326 patients underwent pancreatic head resection. The 90-day mortality increased from 2.9% to 5.3% to 15.4% with increasing age (p = 0,015). There were no differences among the three groups in terms of postoperative morbidity. There was no difference in disease-free survival (DFS), but overall survival was better in patients under 70 years (p = 0,046).

CONCLUSION

Compared to younger patients, patients over 80 years old have a higher risk of mortality despite similar postoperative morbidity.

The Economic Burden of Localized Prostate Cancer and Insights Derived from Cost-Effectiveness Studies of the Different Treatments

Prostate cancer has huge health and societal impacts, and there is no clear consensus on the most effective and efficient treatment strategy for this disease, particularly for localized prostate cancer. We have reviewed the scientific literature describing the economic burden and cost-effectiveness of different treatment strategies for localized prostate cancer in OECD countries. We initially identified 315 articles, studying 13 of them in depth (those that met the inclusion criteria), comparing the social perspectives of cost, time period, geographical area, and severity. The economic burden arising from prostate cancer due to losses in productivity and increased caregiver load is noticeable, but clinical decision-making is carried out with more subjective variability than would be advisable. The direct cost of the intervention was the main driver for the treatment of less severe cases of prostate cancer, whereas for more severe cases, the most important determinant was the loss in productivity. Newer, more affordable radiotherapy strategies may play a crucial role in the future treatment of early prostate cancer. The interpretation of our results depends on conducting thorough sensitivity analyses. This approach may help better understand parameter uncertainty and the methodological choices discussed in health economics studies. Future results of ongoing clinical trials that are considering genetic characteristics in assessing treatment response of patients with localized prostate cancer may shed new light on important clinical and pharmacoeconomic decisions.

Oncological liver resection in elderly - A retrospective comparative study

BACKGROUND

Due to demographic changes and higher life expectancy especially in industrial nations, the number of liver resections in patients ≥70 years is rising. It is known that older age is associated with higher postoperative morbidity and mortality after surgery under general anesthesia. The aim of this analysis is to compare the postoperative outcome after liver resections for malignancies in patients aged below and above 70 years.

MATERIALS AND METHODS

A prospectively collected electronic database of 1034 liver resections between 01/2013 and 12/2019 was retrospectively analyzed. Comparative analysis of patients <70 and ≥ 70 years receiving liver resections for malignancies included 889 operations in 703 patients. Analysis of postoperative outcome and uni- and multivariate analyses of associated risk factors were performed.

RESULTS

Median age of the whole cohort was 65 years (range 18-87 years). N = 582 liver resections (65.7%) were performed in patients <70 years with 42.8% major hepatectomies and n = 307 (34.3%) liver resections in patients ≥70 years with 50.5% major hepatectomies (p = 0.034). Relevant postoperative morbidity of the whole cohort was 27.9%. The 30-day mortality was 3.9% and re-operation rate 14.8%. Patients ≥70 years had significantly higher postoperative morbidity and mortality rates than patients <70 years. Major resections, longer operating time, need of intraoperative transfusions of blood products as well as biliodigestive anastomosis (BDA) and inferior vena cava (IVC) resection were independent risk factors for worse postoperative outcome.

CONCLUSION

Liver resections in patients ≥70 years are associated with a worse postoperative course after. Parenchyma sparing resections should be preferred in those patients.

The Role of Indocyanine Near-Infrared Fluorescence in Colorectal Surgery

Purposes

The aim of this study was to evaluate the importance of Indocyanine Green in control of anastomosis perfusion and on anastomotic leakage rates during laparoscopic and robotic colorectal procedures.

Methods

A retrospective review of patients who underwent elective minimally invasive surgery for colorectal cancer from 1 January 2018 to 31 December 2020 was performed. All patients underwent Near-Infrared Fluorescence-Indocyanine Green system in two moments: before performing the anastomosis and after completing the anastomotic procedure. Primary outcomes were the rate of intraoperative change in the surgical resection due to an inadequate vascularization and the rate of postoperative anastomotic leakage. Secondary outcomes were the postoperative complications, both medical and surgical (intra-abdominal bleeding, anastomotic leakage).

Results

Our analysis included 93 patients. Visible fluorescence was detected in 100% of the cases. In 7 patients (7.5%), the planned site of resection was changed due to inadequate perfusion. The mean extension of the surgical resection in these 7 patients was 2.2 ± 0.62. Anastomotic leakage occurred in 2 patients (2.1%). Other complications included 8 postoperative bleedings (8.6%) and 1 pulmonary thromboembolism.

Conclusions

The intraoperative use of Near-Infrared Fluorescence-Indocyanine Green in colorectal surgery is safe, feasible, and associated with a substantial reduction in postoperative anastomotic leakage rate.

The prevalence and prognostic value of frailty screening measures in patients undergoing surgery for colorectal cancer: observations from a systematic review

Introduction

Frailty is a complex multifactorial syndrome characterised by a significant increase in vulnerability and worsened health outcomes. Despite a range of proposed frailty screening measures, the prevalence and prognostic value of frailty in patients undergoing surgery for colorectal cancer is not clear.

Aim

The aim of this present review was to examine the use of commonly employed frailty screening measures in patients undergoing surgery for colorectal cancer.

Methods

A systematic search of PubMed and Medline was carried out to identify studies reporting the use of frailty screening tools or measures in patients undergoing surgery for colorectal cancer. The screening measure used and prevalence of frailty within the population were recorded. Outcomes of interest were the incidence of post-operative complications, 30-day mortality and overall survival.

Results

Of the 15 studies included (n = 97, 898 patients), 9 studies were retrospective and included patients aged 70 years or older (n = 96, 120 patients). 5 of 12 studies reported that frailty was independently associated with the incidence of post-operative complications. There was also evidence that frailty was independently associated with 30-day mortality (1 of 4 studies, n = 9, 252 patients) and long-term survival (2 of 3 studies, n = 1, 420 patients).

Conclusions

Frailty was common in patients with colorectal cancer and the assessment of frailty may have prognostic value in patients undergoing surgery. However, the basis of the relationship between frailty and post-operative outcomes is not clear and merits further study.

Robot-Assisted vs Laparoscopic Right Hemicolectomy in Octogenarians

OBJECTIVE

With increasing age, there is greater need for right-sided colonic resections than its left-sided counterparts. Older age is associated with limited physical and functional status, which carries greater operative risk. Improvements in robotic surgery questions its role, especially in older adults, compared with laparoscopy. The objective is to investigate whether robotic right hemicolectomy (RRH) is as safe and effective as laparoscopic right hemicolectomy (LHR) in octogenarians (age >80 years).

DESIGN

Retrospective cross-sectional analysis.

SETTINGS AND PARTICIPANTS

Octogenarians who underwent elective RRH and LRH by the Tweed Colorectal Group over 5 years.

METHODS

Complications within 30 days, age, gender, smoking status, immunocompromised status, presence of diabetes, American Society of Anesthesiologists (ASA) physical status score, preoperative Eastern Cooperative Oncology Group (ECOG) performance status, mFI-5 (modified frailty index), operative time, method of anastomosis, postoperative length of stay (LOS), need for rehabilitation, and short-term oncologic data using the TNM criteria were compared using univariate and multivariate analysis.

RESULTS

Seventy-eight elective patients were included. LRH and RRH groups had similar median ages, gender distribution, and comorbidities. Across the entire cohort, 61.5% had no 30-day complications. RRH had nonsignificantly shorter operative time but significantly shorter LOS (5 vs 8 days) and fewer minor complications (24.5% vs 34.5%). Major complications and overall complications were not significantly different between the groups. Lower ASA and ECOG status were associated with lower complication rates across both groups. Oncologic resection outcomes were similar for both approaches.

CONCLUSIONS AND IMPLICATIONS

RRH does not confer an increased risk of complications compared to LRH in the octogenarians and may be a viable alternative in the field of minimally invasive surgery for older patients. Future research should focus on intracorporeal anastomoses, as it is a potential confounder leading to the shorter inpatient LOS shown in our robotic group.

The Prevalence and the Impact of Frailty in Hepato-Biliary Pancreatic Cancers: A Systematic Review and Meta-Analysis

Background: Frailty has been associated with increased mortality among hepatobiliary pancreatic (HBP) cancer patients. Nevertheless, estimates of frailty prevalence in HBP cancers and the precise average effect regarding mortality remains uncertain. The present systematic review and meta-analysis aimed to quantify: (1) the prevalence of frailty in patients with liver and pancreatic cancers and (2) the impact of frailty on mortality in patients affected by liver and pancreatic cancers. Methods: MEDLINE/PubMed database search was conducted from inception until 1 November 2021, the pooled prevalence and relative risk (RR) estimate were calculated. Results: A total of 34,276 patients were identified and the weighted prevalence of frailty was 39%; (95% [C.I.] 23–56; I2 = 99.9%, p < 0.0001). Frailty was significantly associated with increased mortality RR 1.98 (95% [C.I.] 1.49–2.63; I2 = 75.9%, p = 0.006). Conclusions: Frailty prevalence is common among HBP cancer patients and exerts a significant negative impact on survival. These findings are characterized by significant heterogeneity and caution is warranted on their interpretation. However, stratification of patients with HBP cancer by frailty status may provide prognostic information and may inform priorities for decision-making strategy.

The Role of Robotic Visceral Surgery in Patients with Adhesions: A Systematic Review and Meta-Analysis

Abdominal adhesions are a risk factor for conversion to open surgery. An advantage of robotic surgery is the lower rate of unplanned conversions. A systematic review was conducted using the terms “laparoscopic” and “robotic”. Inclusion criteria were: comparative studies evaluating patients undergoing laparoscopic and robotic surgery; reporting data on conversion to open surgery for each group due to adhesions and studies including at least five patients in each group. The main outcomes were the conversion rates due to adhesions and surgeons’ expertise (novice vs. expert). The meta-analysis included 70 studies from different surgical specialities with 14,329 procedures (6472 robotic and 7857 laparoscopic). The robotic approach was associated with a reduced risk of conversion (OR 1.53, 95% CI 1.12–2.10, p = 0.007). The analysis of the procedures performed by “expert surgeons” showed a statistically significant difference in favour of robotic surgery (OR 1.48, 95% CI 1.03–2.12, p = 0.03). A reduced conversion rate due to adhesions with the robotic approach was observed in patients undergoing colorectal cancer surgery (OR 2.62, 95% CI 1.20–5.72, p = 0.02). The robotic approach could be a valid option in patients with abdominal adhesions, especially in the subgroup of those undergoing colorectal cancer resection performed by expert surgeons.

Postoperative Outcomes Analysis After Pancreatic Duct Occlusion: A Safe Option to Treat the Pancreatic Stump After Pancreaticoduodenectomy in Low-Volume Centers

Background: Surgical resection is the only possible choice of treatment in several pancreatic disorders that included periampullar neoplasms. The development of a postoperative pancreatic fistula (POPF) is the main complication. Despite three different surgical strategies that have been proposed–pancreatojejunostomy (PJ), pancreatogastrostomy (PG), and pancreatic duct occlusion (DO)–none of them has been clearly validated to be superior. The aim of this study was to analyse the postoperative outcomes after DO.

Methods: We retrospectively reviewed 56 consecutive patients who underwent Whipple's procedure from January 2007 to December 2014 in a tertiary Hepatobiliary Surgery and Liver Transplant Unit. After pancreatic resection in open surgery, we performed DO of the Wirsung duct with Cyanoacrylate glue independently from the stump characteristics. The mean follow-up was 24.5 months.

Results: In total, 29 (60.4%) were men and 19 were (39.6%) women with a mean age of 62.79 (SD ± 10.02) years. Surgical indications were in 95% of cases malignant diseases. The incidence of POPF after DO was 31 (64.5%): 10 (20.8%) patients had a Grade A fistula, 18 (37.5%) Grade B fistula, and 3 (6.2%) Grade C fistula. No statistical differences were demonstrated in the development of POPF according to pancreatic duct diameter groups (p = 0.2145). Nevertheless, the POPF rate was significantly higher in the soft pancreatic group (p = 0.0164). The mean operative time was 358.12 min (SD ± 77.03, range: 221–480 min). Hospital stay was significantly longer in patients who developed POPF (p < 0.001). According to the Clavien-Dindo (CD) classification, seven of 48 (14.58%) patients were classified as CD III–IV. At the last follow-up, 27 of the 31 (87%) patients were alive.

Conclusions: Duct occlusion could be proposed as a safe alternative to pancreatic anastomosis especially in low-/medium-volume centers in selected cases at higher risk of clinically relevant POPF.

Segmental transverse colectomy. Minimally invasive versus open approach: results from a multicenter collaborative study

The role of minimally invasive surgery in the treatment of transverse colon cancer is still controversial. The aim of this study is to investigate the advantages of a totally laparoscopic technique comparing open versus laparoscopic/robotic approach. Three hundred and eighty-eight patients with transverse colon cancer, treated with a segmental colon resection, were retrospectively analyzed. Demographic data, tumor stage, operative time, intraoperative complications, number of harvested lymph nodes and recovery outcomes were recorded. Recurrences and death were also evaluated during the follow-up. No differences were found between conventional and minimally invasive surgery, both for oncological long-term outcomes (recurrence rate p = 0.28; mortality p = 0.62) and postoperative complications (overall rate p = 0.43; anemia p = 0.78; nausea p = 0.68; infections p = 0.91; bleeding p = 0.62; anastomotic leak p = 0.55; ileus p = 0.75). Nevertheless, recovery outcomes showed statistically significant differences in favor of minimally invasive surgery in terms of time to first flatus (p = 0.001), tolerance to solid diet (p = 0.017), time to first mobilization (p = 0.001) and hospital stay (p = 0.004). Compared with laparoscopic approach, robotic surgery showed significantly better results for time to first flatus (p = 0.001), to first mobilization (p = 0.005) and tolerance to solid diet (p = 0.001). Finally, anastomosis evaluation confirmed the superiority of intracorporeal approach which showed significantly better results for time to first flatus (p = 0.001), to first mobilization (p = 0.003) and tolerance to solid diet (p = 0.001); moreover, we recorded a statistical difference in favor of intracorporeal approach for infection rate (p = 0.04), bleeding (p = 0.001) and anastomotic leak (p = 0.03). Minimally invasive approach is safe and effective as the conventional open surgery, with comparable oncological results but not negligible advantages in terms of recovery outcomes. Moreover, we demonstrated that robotic approach may be considered a valid option and an intracorporeal anastomosis should always be preferred.

Robot-assisted radical prostatectomy in indian men of age 75 years and above: a propensity score-matched analysis

Older men undergoing robot-assisted radical prostatectomy (RARP) have been thought to have worse perioperative, functional and oncological outcomes than younger men. However, there is a dearth of matched studies on this subject in the currently available literature. Our study is a matched pair analysis of perioperative, oncological and functional outcomes of RARP in men < 75 years of age versus ≥ 75 years (62 in each group). There was no statistically significant difference in complications, length of stay, pathological stage, positive surgical margins (PSM) and nodal involvement. Older men were less likely to undergo nerve sparing in our study (8.0 vs 75.8% p = 0.01). Potency rates were too low to be compared. The 1-year continence rates, time to continence and the proportion of men with biochemical recurrence (BCR) were similar between the groups. Men ≥ 75 years developed BCR much earlier than < 75 years (30 versus 78 months p = 0.07). However, this was not statistically significant. Age ≥ 75 years was associated with a statistically insignificant 53.5% rise in the risk of BCR. It was also not associated with any increased risk of postoperative complications or PSM. RARP is a safe procedure in senior adults. The oncological and functional outcomes of RARP in senior adults are similar to younger men.

Robotic Esophagectomy. A Systematic Review with Meta-Analysis of Clinical Outcomes

Background: Robot-Assisted Minimally Invasive Esophagectomy is demonstrated to be related with a facilitation in thoracoscopic procedure. To give an update on the state of art of robotic esophagectomy for cancr a systematic review with meta-analysis has been performed. Methods: a search of the studies comparing robotic and laparoscopic or open esophagectomy was performed trough the medical libraries, with the search string “robotic and (oesophagus OR esophagus OR esophagectomy OR oesophagectomy)”. Outcomes were: postoperative complications rate (anastomotic leakage, bleeding, wound infection, pneumonia, recurrent laryngeal nerves paralysis, chylotorax, mortality), intraoperative outcomes (mean blood loss, operative time and conversion), oncologic outcomes (harvested nodes, R0 resection, recurrence) and recovery outcomes (length of hospital stay). Results: Robotic approach is superior to open surgery in terms of blood loss p = 0.001, wound infection rate, p = 0.002, pneumonia rate, p = 0.030 and mean number of harvested nodes, p < 0.0001 and R0 resection rate, p = 0.043. Similarly, robotic approach is superior to conventional laparoscopy in terms of mean number of harvested nodes, p = 0.001 pneumonia rate, p = 0.003. Conclusions: robotic surgery could be considered superior to both open surgery and conventional laparoscopy. These encouraging results should promote the diffusion of the robotic surgery, with the creation of randomized trials to overcome selection bias.

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.

Robotic versus Laparoscopic Surgery for Spleen-Preserving Distal Pancreatectomies: Systematic Review and Meta-Analysis

Background: When oncologically feasible, avoiding unnecessary splenectomies prevents patients who are undergoing distal pancreatectomy (DP) from facing significant thromboembolic and infective risks. Methods: A systematic search of MEDLINE, Embase, and Web Of Science identified 11 studies reporting outcomes of 323 patients undergoing intended spleen-preserving minimally invasive robotic DP (SP-RADP) and 362 laparoscopic DP (SP-LADP) in order to compare the spleen preservation rates of the two techniques. The risk of bias was evaluated according to the Newcastle–Ottawa Scale. Results: SP-RADP showed superior results over the laparoscopic approach, with an inferior spleen preservation failure risk difference (RD) of 0.24 (95% CI 0.15, 0.33), reduced open conversion rate (RD of −0.05 (95% CI −0.09, −0.01)), reduced blood loss (mean difference of −138 mL (95% CI −205, −71)), and mean difference in hospital length of stay of −1.5 days (95% CI −2.8, −0.2), with similar operative time, clinically relevant postoperative pancreatic fistula (ISGPS grade B/C), and Clavien–Dindo grade ≥3 postoperative complications. Conclusion: Both SP-RADP and SP-LADP proved to be safe and effective procedures, with minimal perioperative mortality and low postoperative morbidity. The robotic approach proved to be superior to the laparoscopic approach in terms of spleen preservation rate, intraoperative blood loss, and hospital length of stay.

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.

Impact of Physical Activity on Disability Risk in Elderly Patients Hospitalized for Mild Acute Diverticulitis and Diverticular Bleeding Undergone Conservative Management

Background and Objectives: The role of physical activity (PA) in elderly patients admitted to surgical units for mild acute diverticulitis in the development of disability has not been clarified so far. Our aim is to demonstrate the relationship between physical activity and better post-discharge outcomes on disability in elderly population affected by diverticular disease. Materials and Methods: We retrospectively reviewed data of 56 patients (32 Males-24 females) collected from October 2018 and March 2020 at Cardarelli Hospital in Campobasso. We included patients older than 65 yrs admitted for acute bleeding and acute diverticulitis stage ≤II, characterized by a good independence status, without cognitive impairment and low risk of immobilization, as evaluated by activity of daily living (ADL) and the instrumental activity of daily living (IADL) and Exton-Smith Scale. "Physical Activity Scale for the Elderly" (PASE) Score evaluated PA prior to admission and at first check up visit. Results: 30.4% of patients presented a good PA, 46.4% showed moderate PA and 23.2% a low PA score. A progressive reduction in ADL and IADL score was associated with lower physical activity (p value = 0.0038 and 0.0017). We consider cognitive performance reduction with a cut off of loss of more than 5 points in Short Port of ADL and IADL and a loss of more than 15 points on Exton-Smith Scale, (p-value 0.017 and 0.010). In the logistic regression analysis, which evaluated the independent role of PASE in disability development, statistical significance was not reached, showing an Odds Ratio of 0.51 95% CI 0.25-1.03 p value 0.062. Discussion: Reduced physical activity in everyday life in elderly is associated with increased post-hospitalization disability regarding independence, cognitive performance and immobilization. Conclusions: Poor physical performance diagnosis may allow to perform a standardized multidimensional protocol to improve PA to reduce disability incidence.

Minimally invasive robotic-assisted combined colorectal and liver excision surgery: feasibility, safety and surgical technique in a pilot series

Different strategies may be adopted in patients with synchronous colorectal liver metastases (LM). The role of laparoscopy has been investigated to define the benefits of minimally invasive surgery in a single-stage operation. In our study, we report our experience of 28 Minimally Invasive Robotic-Assisted combined Colorectal and Liver Excision Surgery (MIRACLES). From October 2012 to December 2019, 135 Robotic liver resections and 218 Robotic Colorectal resections were performed in our center. Twenty-eight patients underwent MIRACLES resection with 37 nodules removed. Fifty-two lesions in 28 patients were resected in minimally invasive robot-assisted surgery. Eighteen lesions were located in postero-superior liver segments (eight in segment VII, two in segment VIII, eight in segment IVa). Nine right colectomies, seven left colectomies, ten anterior rectal resections, one Hartmann and one MILES procedures were performed. The median surgical time of MIRACLES procedures was 332 min. Two conversions to open approach were necessary. Four major complications (> III) were observed. No postoperative mortality was recorded. The median hospital stay was 8 days. The median overall survival was 27.5 months. The MIRACLES approach is feasible and safe for colorectal resection and hepatic nodules located in all segments, with a low rate of postoperative complications. Surgical technique is demanding and should be reserved, presently, to tertiary centers.

Feasibility of robot-assisted surgery in elderly patients with rectal cancer

Background:

Although surgical resection is the main treatment for rectal cancer, the optimal surgical protocol for elderly patients with rectal cancer remains controversial. This study evaluated the feasibility of robot-assisted surgery in elderly patients with rectal cancer.

Patients and Methods:

This retrospective study enrolled 156 patients aged 28–93 years diagnosed with Stage I–III rectal cancer, who underwent robot-assisted surgery between May 2013 and December 2018 at a single institution.

Results:

In total, 156 patients with rectal cancer, including 126 non-elderly (aged < 70 years) and 30 elderly (aged ≥70 years) patients, who underwent robot-assisted surgery were recruited. Between the patient groups, the post-operative length of hospital stay did not differ statistically significantly (P = 0.084). The incidence of overall post-operative complications was statistically significantly lower in the elderly group (P = 0.002). The disease-free and overall survival did not differ statistically significantly between the two groups (P = 0.719 and 0.390, respectively).

Conclusions:

Robot-assisted surgery for rectal cancer was well tolerated by elderly patients, with similar results to the non-elderly patients. Oncological outcomes and survival did not depend on patient age, suggesting that robot-assisted surgery is a feasible surgical modality for treating operable rectal cancer and leads to age-independent post-operative outcomes in elderly patients.

Conversions related to adhesions in abdominal surgery. Robotic versus laparoscopic approach: A multicentre experience

BACKGROUND

An advantage of robotic surgery over laparoscopy is the lower rate of unplanned conversion. One of the implicated reasons for conversion is adhesions from previous abdominal surgeries (PASs).

METHODS

A comparative analysis of 98 patients with history of open PAS treated by laparoscopic or robotic surgery was performed. Primary endpoint was the rate of conversion to open surgery related to adhesiolysis. Secondary endpoints were short-term outcomes and complications.

RESULTS

Conversion rate specifically related to adhesiolysis was significantly lower in robotic group (13 for laparoscopic group vs. 2 for robotic group; p = 0.046). Conversions occurred during adhesiolysis were significantly related to severity of adhesions expressed by peritoneal adhesion index (PAI) score (p < 0.001), number of abdominal areas involved by adhesions (p < 0.001) and severity of PAI into the target area of surgical intervention (p = 0.021).

CONCLUSIONS

Benefits of robotic surgery are more noticeable in performing procedures with increasing technical difficulties.

Robotic versus open oncological gastric surgery in the elderly: a propensity score-matched analysis

Although there is no agreement on a definition of elderly, commonly an age cutoff of ≥ 65 or 75 years is used. Even if robot-assisted surgery is a validated option for the elderly population, there are no specific indications for its application in the surgical treatment of gastric cancer. The aim of this study is to evaluate the safety and feasibility of robot-assisted gastrectomy and to compare the short and long-term outcomes of robot-assisted (RG) versus open gastrectomy (OG). Patients aged ≥ 70 years old undergoing surgery for gastric cancer at the Department of Surgery of San Donato Hospital in Arezzo, between September 2012 and March 2017 were enrolled. A 1:1 propensity score matching was performed according to the following variables: age, Sex, BMI, ASA score, comorbidity, T stage and type of resection performed. 43 OG were matched to 43 RG. The mean operative time was significantly longer in the RG group (273.8 vs. 193.5 min, p < 0.01). No differences were observed in terms of intraoperative blood loss, an average number of lymph nodes removed, mean hospital stay, morbidity and mortality. OG had higher rate of major complications (6.9 vs. 16.3%, OR 2.592, 95% CI 0.623–10.785, p = 0.313) and a significantly higher postoperative pain (0.95 vs. 1.24, p = 0.042). Overall survival (p = 0.263) and disease-free survival (p = 0.474) were comparable between groups. Robotic-assisted surgery for oncological gastrectomy in elderly patients is safe and effective showing non-inferiority comparing to the open technique in terms of perioperative outcomes and overall 5-year survival.

Robotic repair of iatrogenic left diaphragmatic hernia. A case report

INTRODUCTION

Iatrogenic diaphragmatic hernia after laparoscopic left adrenalectomy has been rarely reported in adults. Surgery is the preferred treatment because of the risks of incarceration, strangulation and pulmonary complications.

PRESENTATION OF CASE

An elderly woman with parasternal diaphragmatic hernia has been successfully treated by robotic repair with mesh placement. The short-term follow-up showed that there was no recurrence or any symptoms after the intervention.

DISCUSSION

Iatrogenic diaphragmatic hernia is a rare complication occurring after abdominal or thoracic surgery. The diagnosis could be challenging because of the presence of chronic symptoms. Computed tomography can be considered the gold standard technique to assess the correct diagnosis of diaphragmatic hernias in the majority of cases. Patients with chronic symptomatic hernia should undergo surgical repair of defect. Robotic technology because of its enhanced precision and the endowrist movement of the robotic arms, facilitates the dissection near the esophago-gastric junction and the other important adjacent structures.

CONCLUSION

Robotic technology seems to be a valid approach for the repair of diaphragmatic defects, even if this remains a high cost-related procedure.

Perioperative Management of Elderly patients (PriME): recommendations from an Italian intersociety consensus

BACKGROUND

Surgical outcomes in geriatric patients may be complicated by factors such as multiple comorbidities, low functional performance, frailty, reduced homeostatic capacity, and cognitive impairment. An integrated multidisciplinary approach to management is, therefore, essential in this population, but at present, the use of such an approach is uncommon. The Perioperative Management of Elderly patients (PriME) project has been established to address this issue.

AIMS

To develop evidence-based recommendations for the integrated care of geriatric surgical patients.

METHODS

A 14-member Expert Task Force of surgeons, anesthetists, and geriatricians was established to develop evidence-based recommendations for the pre-, intra-, and postoperative care of hospitalized older patients (≥ 65 years) undergoing elective surgery. A modified Delphi approach was used to achieve consensus, and the strength of recommendations and quality of evidence was rated using the U.S. Preventative Services Task Force criteria.

RESULTS

A total of 81 recommendations were proposed, covering preoperative evaluation and care (30 items), intraoperative management (19 items), and postoperative care and discharge (32 items).

CONCLUSIONS

These recommendations should facilitate the multidisciplinary management of older surgical patients, integrating the expertise of the surgeon, the anesthetist, the geriatrician, and other specialists and health care professionals (where available) as needed. These roles may vary according to the phase and setting of care and the patient's conditions.

Influence of robotics in surgical complication rate in elderly population with rectal cancer

BACKGROUND

Rectal cancer surgery is a technically complex procedure. Moreover, short-term outcomes show high rate of complications especially in elderly and laparoscopic surgery has not demonstrated to be able to reduce this complication rate. Robotics has several advantages in pelvic surgical procedures, which could have an impact in complication rates in elderly patients.

AIMS

The aim of our study is to demonstrate whether robotic surgery has any influence on the reduction of complications in the aged population undergoing rectal cancer.

METHODS

We performed a retrospective analysis of a prospective database of 151 patients who underwent robotic surgery for rectal cancer. We divided our population into three groups: under 65-year-old, between 65- and 80-year-old and above 80-year-old. We recorded complications in each group intra and post procedure.

RESULTS

The present study included 151 patients (94 males). Of them, 77 patients were under 66 year old, 63 patients were between 66 and 79 year old and 11 patients were 80 year old and above. The analysis showed conversion rates of 10.38%, 13.69%, 27.27%, and the complication rate of 23.4%, 23.8%, and 27.3% in each group. Univariate analysis showed no differences between the three groups. Nevertheless, there were statistical differences from BMI, ASA and neoadjuvant therapy. In multivariant analysis only neoadjuvant therapy was significant.

CONCLUSIONS

Robotic approach does not decrease complications in elderly population and conversion is similar in these age groups. So we should not rule out robotic surgery in elderly patients, although we must select each case with a multidisciplinary approach.

Minimizing the impact of colorectal surgery in the older patient: The role of minimally invasive surgery in the geriatric population

With an aging population comes a greater incidence of colorectal cancer and a corresponding need for surgical resection in the geriatric population. This heterogeneous group of patients may benefit from multidisciplinary pre-operative evaluation and optimization, prehabilitation, enhanced recovery protocols, and a minimally invasive approach to resection. Concerns regarding the ability of the older patient to tolerate the physiologic demands of pneumoperitoneum have not been validated. Conversely, these vulnerable patients may experience a greater reduction in morbidity than their younger counterparts through the use of minimally invasive techniques.

Predictive value of preoperative weight loss on survival of elderly patients undergoing surgery for esophageal squamous cell carcinoma

Background

The role of preoperative weight loss (PWL) has rarely been studied in elderly patients undergoing surgery for esophageal squamous cell carcinoma (ESCC). The aim of this study is to evaluate whether PWL is an important determinant of survival in elderly patients following surgery for ESCC.

Methods

This retrospective study included a total of 974 elderly patients (≥65 years) who underwent esophagectomy for ESCC at the West China Hospital, Sichuan University from August 2005 to April 2013. PWL was determined as the percentage weight loss during the 3 months before admission. Patients were divided into three groups according to the PWL, defined as normal (PWL =0), slight PWL (0< PWL <10%) and severe PWL (PWL ≥10%). Prognostic factors were evaluated by using univariate and multivariate analyses.

Results

Patients were categorized as normal (n=605, 62.11%), slight PWL (n=284, n=29.17%) and severe PWL (n=85, 8.73%). Compared with patients without PWL, both the patients with slight and severe PWL suffered from higher risk of tumor depth invasion (P=0.002 and P<0.001, respectively), lymph node metastasis (P=0.009 and P=0.004, respectively) and advanced stage (P=0.006 and P<0.001, respectively). Both patients with slight and severe PWL were significantly associated with worse overall survival compared with patients without PWL (P=0.036 and P<0.001, respectively). Multivariate analysis revealed severe PWL was an independent prognostic factor of overall survival [hazard ratio (HR) =1.534, 95% CI: 1.163-2.024] after correcting for sex, body mass index (BMI), T stage, N stage, grade, and adjuvant therapy.

Conclusions

For elderly patients undergoing surgery for ESCC, PWL provided prognostic value for depth of tumor invasion, lymph node metastasis and advanced stage. PWL ≥10% was an independent predictor of worse overall survival.

Clinico-pathological Features of Colon Cancer Patients Undergoing Emergency Surgery: A Comparison Between Elderly and Non-elderly Patients

BACKGROUND

Colorectal cancer (CRC) is one of the most common cancers in patients older than 65 years. Emergency presentation represents about 30% of cases, with increased morbidity and mortality rates. The aim of this study is to compare the perioperative outcome between elderly and non-elderly patients undergoing emergency surgery.

METHOD

We retrospectively analysed CRC patients that underwent emergency surgery at the Departments of Surgery of the Sapienza University Sant'Andrea Hospital in Rome, and at San Donato Hospital in Arezzo, between June 2012 and June 2017. Patients were divided into two groups: non-elderly (< 65 years) and elderly (≥ 65 years). Variables analysed were sex, onset symptoms, associated disease, ASA score, tumor site and TNM stage, surgical procedures and approach, and morbidity and mortality.

RESULTS

Of a total of 123 patients, 29 patients were non-elderly and 94 patients were elderly. No significant differences were observed in sex, onset symptoms and tumor site between the two groups. Comorbidities were significantly higher in elderly patients (73.4% vs 41.4%, p<0.001). No significant differences were observed between the two groups in surgical approach and the rate of one-stage procedures. Elderly patients were more frequently treated by Hartmann's procedure compared to non-elderly patients (20.2% vs 6.9%). Left colorectal resection with protective ileostomy was most frequent in the non-elderly group (27.6% vs 11.7%). No significant differences were found in the pT and pN categories of the TNM system between the two groups. However, a higher number of T3 in non-elderly patients was observed. A consistent number of non-oncologically adequate resections were observed in the elderly (21.3% vs 3.5%; p<0.03). The morbidity rate was significantly higher in the elderly group (31.9 % vs 3.4%, p<0.001). No significant difference was found in the mortality rate between the two groups, being 13.8% in the elderly and 6.9% in the non-elderly.

CONCLUSIONS

Emergency colorectal surgery for cancer still presents significant morbidity and mortality rates, especially in elderly patients. More aggressive tumors and advanced stages were more frequent in the non-elderly group and as a matter it should be taken into account when treating such patients in the emergency setting in order to perform a radical procedure as much as possible.

Surgical decision-making for rectal prolapse: one size does not fit all

BACKGROUND

Surgery remains the only known treatment option for rectal prolapse. Although over 100 abdominal and perineal procedures are available, there is no consensus as to which intervention is best suited for an individual. This retrospective cohort study describes the patient- and disease-related factors involved in making surgical recommendations around rectal prolapse in a single surgeon experience.

METHODS

91 consecutive patients ≥18 years old diagnosed with external and/or high-grade internal rectal prolapse were assessed and were prospectively entered into an IRB approved registry. Information on patient symptoms, comorbidities, exam findings, surgeon judgment, and patient preference was collected. Treatment recommendations (abdominal, perineal, or no operation) were analyzed and compared.

RESULTS

Surgical intervention was recommended to 93% of patients. Of those, 66% were recommended robotic abdominal procedures: 75%, robotic ventral mesh rectopexies; 16%, resection rectopexies; and 9%, suture rectopexies. On univariate analysis, patients with older age, higher ASA scores, presence of cardiopulmonary morbidity, pain as a primary rectal prolapse symptom, rectal prolapse always descended, and surgeon concern for frailty and general anesthesia were associated with recommendations for perineal operations (p < 0.05 for all). However, on multivariate analysis, only age and concern over prolonged anesthesia remained correlated with a recommendation for perineal surgery. Of patients >80 years of age, 15% were recommended an abdominal approach.

CONCLUSIONS

With multiple options available for the treatment of rectal prolapse, treatment recommendations remain surgeon-dependent and may be influenced by many factors. In our practice, robotic ventral mesh rectopexy was the most commonly recommended operation and was offered to carefully selected patients of advanced age. Although robotic surgery and ventral mesh rectopexy may not be accessible to all patients and surgeons, this represents a single surgeon's practice bias. This study reinforces the importance of perineal procedures for higher-risk individuals.

Providing Aging Adults Social Robots' Companionship in Home-Based Elder Care

Population aging is increasingly serious. The application of social robots for home-based elder care is an important way to solve this problem. Aging adults' demands for social robots' companionship affect robotic designs. This study aimed to investigate aging adults' demands for social robots' companionship and explored in which life situations it was appropriate to accompany aging adults by social robots. This study involved three phases. Phase 1 (an interview survey) collected the life situations in which aging adults lived alone at home. Based on the results of Phase 1, Phase 2 (a questionnaire survey) investigated aging adults' demands for companionship, whereas Phase 3 (an expert evaluation) investigated the feasibility of the robots' companionship for aging adults. After the three phases, this study compared aging adults' demands for companionship with the feasibility of social robots' companionship in each life situation. Based on the results, the life situations of dinning and watching TV, there was a greater likelihood that the companionship that aging adults needed might be provided by social robots. In the life situations of sleeping and short breaking, it was difficult that aging adults' demands for companionship were fulfilled by social robots. Implications were discussed for home-based elder care system.

Is it safe to perform gastrectomy in gastric cancer patients aged 80 or older?: A meta-analysis and systematic review

BACKGROUND

Few studies have focused on octogenarian patients with gastric cancer (GC) who have undergone gastrectomy. This meta-analysis of published studies was performed to assess the safety of treating octogenarian GC patients with surgery.

METHODS

Databases, including PubMed, Embase, Web of Science, and Cochrane Library were searched until January 2019. The incidence of preoperative comorbidities, postoperative complications, and mortality was assessed using odds ratios (ORs) with corresponding 95% confidence intervals (CIs). Further, the hazard ratios (HRs) with 95% CIs were applied for survival outcomes.

RESULTS

A total of 18,179 patients with GC in 21 studies were included. Our results demonstrated that octogenarian patients were associated with a higher burden of comorbidities (OR = 2.79; 95% CI: 2.37, 3.28; P = .00), high incidences of overall postoperative complications (OR = 1.48; 95% CI: 1.22, 1.81; P = .00), medical postoperative complications (OR = 2.58; 95% CI: 1.91, 3.49; P = .00), in-hospital mortality (OR = 3.24; 95% CI: 2.43, 4.31; P = .00) and poor overall survival (HR = 1.96; 95% CI: 1.65, 2.27; P = .00).

CONCLUSIONS

Considering the high burden of comorbidities, high incidences of postoperative complications and mortality, surgery for extremely elderly patients with GC requires deliberation. Individualized treatment is recommended for such patients.

Management of Complications of First Instance of Hepatic Trauma in a Liver Surgery Unit: Portal Vein Ligation as a Conservative Therapeutic Strategy

BACKGROUND

According to the National Trauma Data Bank, the liver, after the spleen, is the first most injured organ in closed abdominal trauma.

METHODS

From June 2010 to December 2015 we observed in our department of Hepato-biliary Surgery and Liver Transplant Unit of the A.O.R.N. A. Cardarelli of Naples 40 patients affected by hepatic trauma. In our retrospective study, we review our experience and propose portal vein ligation (PVL) as a first - line strategy for damage control surgery (DCS) in liver trauma.

RESULTS

26/40 patients (65%) which received gauze-packing represented our study group. In 10 cases out of 26 patients (38,4%) the abdominal packing was enough to control the damage. In 7 cases (18,4%) we performed a liver resection. In 7 cases, after de-packing, we adopted PVL to achieve DCS. Trans Arterial Embolization was chosen in 6 patients. 2 of them were discharged 14 days later without performing any other procedure.In 3 cases we had to perform a right epatectomy in second instance. Two hepatectomies were due to hemoperitoneum, and the other for coleperitoneum. Two patients were treated in first instance by only doing hemostasis on the bleeding site. We observed 6 patients in first instance. Five of them underwent surgery with hepatic resection and surgical hemostasis of the bleeding site. The other one underwent to conservative management. In summary we performed 15 hepatic resections, 8 of them were right hepatectomies, 1 left hepatectomy, 2 trisegmentectomies V-VI-VII. So in second instance we operated on 10 patients out of 34 (30%).

CONCLUSIONS

The improved knowledge of clinical physio-pathology and the improvement of diagnostic and instrumental techniques had a great impact on the prognosis of liver trauma. We think that a rigid diagnostic protocol should be applied as this allows timely pathological finding, and consists of three successive but perfectly integrated steps: 1) patient reception, in close collaboration with the resuscitator; 2) accurate but quick diagnostic framing 3) therapeutic decisional making. Selective portal vein ligation is a well-tolerated and safe manoeuvre, which could be effective, even if not definitive, in treating these subjects. That is why we believe that it can be a choice to keep in mind especially in post-depacking bleeding.

Laparoscopic hepatectomy for elderly patients: Major findings based on a systematic review and meta-analysis

BACKGROUND

As the general population continues to age, there is an increase need for surgical management of elderly patients. Compared to open hepatectomy (OH), laparoscopic hepatectomy (LH) offers earlier mobilization, less blood loss, and shorter postoperative hospital stay. However, whether these advantages of LH over OH are retained in elderly patients remains to be clarified. Therefore, in this study, we sought to evaluate the feasibility, safety, and potential benefits of LH for elderly patients.

METHODS

A systematic search of PubMed, Embase, Cochrane Library, and Web of Science was performed to identify studies that compared LH and OH. Studies comparing LH in elderly and LH in nonelderly patients were also identified. Outcomes of interest included conversion rate, operative time, intraoperative estimated blood loss, length of hospital stay, rate and type of morbidity, mortality rate, margin status (R0), and long-term oncologic outcomes.

RESULTS

Nine studies met our inclusion criteria for this analysis. Of these, 5 compared LH and OH in elderly patients, 3 compared LH in elderly and nonelderly patients, and 1 included both outcomes. Compared to those with OH, elderly patients who underwent LH had similar operative times [weighted mean difference (WMD) = 1.15 minutes; 95% confidence interval (CI): -28.28-30.59, P = .94], less intraoperative blood loss (WMD = -0.71 mL; 95% CI: -1.29 to -0.16, P = .01), a lower rate of transfusion [risk ratio (RR) = 0.61, 95% CI: 0.40-0.94, P = .02], comparable R0 rates (RR = 1.01; 95% CI: 0.96-1.07, P = .70), less postoperative complications (RR = 0.61, 95% CI: 0.48-0.76, P < .01), and shorter hospital stay (WMD = -3.22 days; 95% CI: -4.21 to -2.23, P < .01). The limited long-term outcomes indicated that survival status was comparable between LH and OH for elderly patients. The pooled outcomes for elderly versus nonelderly patients indicated that the safety and effectiveness of LH over OH in elderly patients was not inferior to those in nonelderly patients.

CONCLUSION

Our results indicate that LH is a feasible and safe alternative to OH in elderly patients, providing a lower rate of morbidity and favorable postoperative recovery and outcomes.

Robot-assisted liver surgery in a general surgery unit with a "Referral Centre Hub&Spoke Learning Program". Early outcomes after our first 70 consecutive patients

BACKGROUND

The aim of this study was to evaluate safety, feasibility and short-term outcomes of our first 70 consecutive patients treated by robotic-assisted liver resection after a reversal proctoring between a high HPB volume centre and our well-trained center in minimally invasive General Surgery. Six surgeons were involved in this Hub&Spoke learning program.

METHODS

From September 2012 to December 2016, 70 patients underwent robotic-assisted liver resections (RALR). We treated 18 patients affected by colorectal and gastric cancer with synchronous liver lesions suspected for metastases in a one-stage robotic-assisted procedure. For the first 20 procedures we had a tutor in the operatory room, who was present also in the next most difficult procedures.

RESULTS

The 30- and 90-day mortality rate was zero with an overall morbidity rate of 10.1%. Associated surgical procedures were performed in about 65,7% of patients. The observed conversion rate was 10%. The results of the first 20 cases were similar to the next 50 showing a shortned learning curve.

CONCLUSIONS

Minimally invasive robot-assisted liver resection is a safe technique; it allows overcoming many limits of conventional laparoscopy. This innovative, time-enduring Hub&Spoke may allow patients to undergo a proper standard of care also for complex surgical procedures, without the need of reaching referral centres.

Safety and oncologic outcomes of robotic liver resections: A systematic review

The robotic system has emerged as a new minimally invasive technology with promising results. We sought to systematically review the available literature on the safety and the oncologic outcomes of robotic liver surgery. A systematic review was conducted using Medline (PubMed), Embase and Cochrane library through November 12th, 2017. A robotic approach may be a safe and feasible surgical option for minor and major liver resections.

Metal substitutions incarbonic anhydrase: a halide ion probe study

The ASA score is known to be an independent predictor of complications and mortality following colorectal surgery. We evaluated early outcome in the initiation phase of a robotic oncological colorectal resection program in dependence of comorbidity and learning curve. 43 consecutive colorectal cancer patients (median age: 74 years) who underwent robotic surgery were firstly analysed defined by physical status (group A = ASA1 + 2; group B = ASA3). Secondly, outcome was evaluated relating to surgery date (group E: early phase; group L: late phase). There were no differences among groups A and B with regard to gender, BMI, skin-to-skin operative times (STS), N- and M-status, hospital-stay as well as overall rate of complications according to Dindo-Clavien and no one-year mortality. GroupA when compared to group B demonstrated significantly lower mean age (65.5 years ± 11.4 years vs 75.8 years  ± 8.9 years), T-stage and ICU-stay. When separately analyzed for patients age ICU-stay was comparable (> 75 years vs. < 75 years). Group E and L demonstrated comparable characteristics and early outcome except more frequent lymphatic fistulas in group E. STS was reduced in group L compared to group E. Beyond learning curve aspects in our series, we could demonstrate that patient’s physical condition according to ASA rather than age may have an impact on early outcome in the initial phase of a robotic oncological colorectal program.
