RESUMO
AIM: Colorectal cancer (CRC) surgery can be associated with suboptimal outcomes in older patients. The aim was to identify the correlation between frailty and surgical variables with the achievement of Textbook Outcome (TO), a composite measure of the ideal postoperative course, by older patients with CRC. METHOD: All consecutive patients ≥70years who underwent elective CRC-surgery between January 2017 and November 2021 were analyzed from a prospective database. To obtain a TO, all the following must be achieved: 90-day survival, Clavien-Dindo (CD) < 3, no reintervention, no readmission, no discharge to rehabilitation facility, no changes in the living situation and length of stay (LOS) ≤5days/≤14days for colon and rectal surgery respectively. Frailty and surgical variables were related to the achievement of TO. RESULTS: Four-hundred-twenty-one consecutive patients had surgery (97.7% minimally invasive), 24.9% for rectal cancer, median age 80 years (range 70-92), median LOS of 4 days (range 1-96). Overall, 288/421 patients (68.4%) achieved a TO. CD 3-4 complications rate was 6.4%, 90-day mortality rate was 2.9%. At univariate analysis, frailty and surgical variables (ileostomy creation, p = 0.045) were related to. However, multivariate analysis showed that only frailty measures such as flemish Triage Risk Screening Tool≥2 (OR 1.97, 95%CI: 1.23-3.16; p = 0.005); Charlson Index>6 (OR 1.61, 95%CI: 1.03-2.51; p = 0.036) or Timed-Up-and-Go>20 s (OR 2.06, 95%CI: 1.01-4.19; p = 0.048) independently predicted an increased risk of not achieving a TO. CONCLUSION: The association between frailty and comprehensive surgical outcomes offers objective data for guiding family counseling, managing expectations and discussing the possible loss of independence with patients and caregivers.

INTRODUCTION: The oncological outcomes of low ligation (LL) compared to high ligation (HL) of the inferior mesenteric artery (IMA) during low-anterior rectal resection (LAR) with total mesorectal excision are still debated. The aim of this study is to report the 5 year oncologic outcomes of patients undergoing laparoscopic LAR with either HL vs. LL of the IMA MATERIALS AND METHODS: Between June 2014 and December 2016, patients who underwent elective laparoscopic LAR + TME in 6 Italian non-academic hospitals were randomized to HL or LL of IMA after meeting the inclusion criteria (HighLow trial; ClinicalTrials.gov Identifier NCT02153801). We analyzed the rate of local recurrence, distant metastasis, overall survival, disease-specific survival, and disease-free survival at 5 years of patients previously enrolled. RESULTS: Five-year follow up data were available for 196 patients. Recurrence happened in 42 (21.4%) of patients. There was no statistically significant difference in the distant recurrence rate (15.8% HL vs. 18.9% LL; P = 0.970) and pelvic recurrence rate (4,9% HL vs 3,2% LL; P = 0.843). No statistically significant difference was found in 5-year OS (p = 0.545), DSS (p = 0.732) or DFS (p = 0.985) between HL and LL. Low vs medium and upper rectum site of tumor, conversion rate, Clavien-Dindo post-operative grade ≥3 complications and tumor stage were found statistically significantly associated to poor oncological outcomes in univariate analysis; in multivariate analysis, however, only conversion rate and stage 3 cancer were found to be independent risk factors for poor DFS at 5 years. CONCLUSION: We confirmed the results found in the previous 3-year survival analysis, the level of inferior mesenteric artery ligation does not affect OS, DSS and DFS at 5-year follow-up.

BACKGROUND: Enhanced Recovery After Surgery (ERAS) represents the standard of care in colorectal surgery. Among ERAS items, early removal of urinary catheter (UC) is considered a key issue, though adherence to this specific item still varies among centers. UC placement allows for monitoring of post-operative urinary output but relates to an increased risk of urinary tract infection (UTI), reduced mobility, and patient's discomfort. Several studies investigated the role of early UC removal specifically looking at the rate of acute urinary retention (AUR) but most of them were retrospective, single-center, underpowered, cohort studies. The main purpose of this study is to compare the rate of AUR after immediate (at the end of the surgery) versus early (within 24 h from the completion of surgery) removal of UC in patients undergoing minimally invasive colonic resection (MICR). The secondary outcomes focus on goals that could be positively impacted by the immediate removal of the UC at the end of the surgery. In particular, the rate of UTIs, perception of pain, time-to-return of bowel and physical functions, postoperative complications, and length of hospital stay will be measured. METHODS: This is a prospective, randomized, controlled, two-arm, multi-center, study comparing the rate of AUR after immediate versus early removal of UC in patients undergoing MICR. The investigators hypothesize that immediate UC removal is non-inferior to 24-h UC removal in terms of AUR rate. Randomization is at the patient level and participants are randomized 1:1 to remove their UC either immediately or within 24 h from the completion of surgery. Those eligible for inclusion were patients undergoing any MICR with an anastomosis above the peritoneal reflection. Those patients who need to continue urinary output monitoring after the surgery will be excluded. The number of patients calculated to be enrolled in each group is 108 based on an expected AUR rate of 3% for the 24-h UC removal group and considering acceptable an AUR of 9% for the immediate UC removal group. DISCUSSION: The demonstration of a non-inferiority of immediate versus 24-h removal of UC would call into question the usefulness of urinary drainage in the setting of MICR. TRIAL REGISTRATION: ClinicalTrials.gov NCT05249192. Prospectively registered on February 21, 2022.

BACKGROUND: While elective surgery was shut down in most settings during the 2019 novel coronavirus pandemic, some referral centers were designated as surgery hubs. We sought to investigate how the pandemic scenario impacted the quality of a long-established enhanced recovery protocol colorectal surgery program in 2 referral centers, designated as colorectal surgery hubs, located in the epicentral Italian regions hardest hit by the pandemic. METHODS: We compared short-term outcomes of patients undergoing major colorectal surgery with a long-established enhanced recovery protocol during the coronavirus disease 2019 outbreak occurred in 2020 (group A) with the correspondent timeframe of 2019 (group B). Primary outcomes were morbidity and mortality, duration of stay, and readmission rate. RESULTS: One hundred and thirty-six patients underwent major colorectal surgery in group A and 173 in group B. Postoperative complications and readmission rate were comparable between the 2 groups. Oncologic case-log was predominant in group A compared with group B (73.5 vs 61%; P = .01). A significantly shorter overall duration of stay was found in group A (P < .001). Uncomplicated patients of group A had a shorter duration of stay when compared with uncomplicated patients of group B (P = .008). CONCLUSION: Under special precautionary measures, major colorectal surgery can be undertaken on elective basis even during coronavirus disease 2019 pandemic with reasonable results. A reduction of duration of stay within a long-established enhanced recovery protocol colorectal surgery program was observed during the coronavirus disease 2019 pandemic occurred in 2020 in comparison with the correspondent timeframe of the previous year without compromising short-term outcomes. The pandemic uncovered the positive impact of patients' commitment to reducing duration of stay as the empowered risk awareness likely promoted their compliance to the enhanced recovery protocol.

BACKGROUND: Senior adults fear postoperative loss of independence the most, and this might represent an additional burden for families and society. The number of geriatric patients admitted to the emergency room requiring an urgent surgical treatment is rising, and the presence of frailty is the main risk factor for postoperative morbidity and functional decline. Frailty assessment in the busy emergency setting is challenging. The aim of this study is to verify the effectiveness of a very simple five-item frailty screening tool, the Flemish version of the Triage Risk Screening Tool (fTRST), in predicting functional loss after emergency surgery among senior adults who were found to be independent before surgery. METHODS: All consecutive individuals aged 70 years and older who were independent (activity of daily living (ADL) score ≥5) and were admitted to the emergency surgery unit with an urgent need for abdominal surgery between December 2015 and May 2016 were prospectively included in the study. On admission, individuals were screened using the fTRST and additional metrics such as the age-adjusted Charlson Comorbidity Index (CACI) and the ASA score. Thirty- and 90-day complications and postoperative decline in the ADL score where recorded. Regression analysis was performed to identify preoperative predictors of functional loss. RESULTS: Seventy-eight patients entered the study. Thirty-day mortality rate was 12.8% (10/78), and the 90-day overall mortality was 15.4% (12/78). One in every four patients (17/68) experienced a significant functional loss at 30-day follow-up. At 90-day follow-up, only 3/17 patients recovered, 2 patients died, and 12 remained permanently dependent. On the regression analysis, a statistically significant correlation with functional loss was found for fTRST, CACI, and age≥85 years old both at 30 and 90 days after surgery. fTRST≥2 showed the highest effectiveness in predicting functional loss at 90 days with AUC 72 and OR 6.93 (95% CI 1.71-28.05). The institutionalization rate with the need to discharge patients to a healthcare facility was 7.6% (5/66); all of them had a fTRST≥2. CONCLUSION: fTRST is an easy and effective tool to predict the risk of a postoperative functional decline and nursing home admission in the emergency setting.

Objectives: To determine the disease-free survival (DFS), disease-specific survival (DSS), and recurrence in patients who underwent laparoscopic low anterior rectal resection with total mesorectal excision (TME) with either high or low ligation of the inferior mesenteric artery (IMA). Background: The level of IMA ligation during anterior rectal resection with TME is still a matter of debate, especially in terms of oncological adequacy. Methods: Between June 2014 and December 2016, patients scheduled to undergo elective laparoscopic low anterior resection (LAR) and TME in 6 Italian nonacademic hospitals were randomized into 2 groups in the HIGHLOW Trial (ClinicalTrials.gov Identifier: NCT02153801) according to the level of IMA ligation: high ligation (HL) versus low ligation (LL). DFS, DSS, and recurrence were inquired. Recurrence was determined at 3, 6, 9, and 12 months and every 6 months thereafter. Patients and tumor characteristics as well as surgical outcomes were analyzed to identify risk factors for recurrence. Results: One hundred ninety-six patients from the HIGHLOW trial were analyzed. Median follow-up for DFS was 40.6 (interquartile range [IQR], 6-64.7) and 40 (IQR, 7.6-67.8), while median follow-up for DSS was 41.2 (IQR, 10.7-64.7) and 42.7 (IQR, 6-67.6) in the HL and LL groups, respectively. The 3-year DFS rate of HL and LL patients was 82.2% and 82.1% (P = 0.874), respectively. The 3-year DSS for HL and LL patients was 92.1% and 93.4% (P = 0.897), respectively. There was no statistically significant difference in the local recurrence rate (2% HL vs 2.1% LL), in the regional recurrence rate (3% HL vs 2.1% LL), and in the distant recurrence rate (12.9% HL vs 13.7% LL). Multivariate analysis found conversion to open surgery (hazard ratio [HR], 3.68; P = 0.001) and higher stage of disease (HR, 7.73; P < 0.001) to be significant determinant for DFS. Conclusions: The level of inferior mesenteric artery ligation during LAR and TME for rectal cancer does not affect DFS, DSS, and recurrence.
RESUMO
Importance: Several techniques are used for surgical treatment of gallstone disease with biliary duct calculi, but the safety and efficacy of these approaches have not been compared. Objectives: To compare the efficacy and safety of 4 surgical approaches to gallstone disease with biliary duct calculi. Data Sources: MEDLINE, Scopus, and ISI-Web of Science databases, articles published between 1950 and 2017 and searched from August 12, 2017, to September 14, 2017. Search terms used were LCBDE, LC, preoperative, ERCP, postoperative, period, cholangiopancreatography, endoscopic, retrograde, rendezvous, intraoperative, one-stage, two-stage, single-stage, gallstone, gallstones, calculi, stone, therapy, treatment, therapeutics, surgery, surgical, procedures, clinical trials as topic, random, and allocation in several logical combinations. Study Selection: Randomized clinical trials comparing at least 2 of the following strategies: preoperative endoscopic retrograde cholangiopancreatography (PreERCP) plus laparoscopic cholecystectomy (LC); LC with laparoscopic common bile duct exploration (LCDBE); LC plus intraoperative endoscopic retrograde cholangiopancreatography (IntraERCP); and LC plus postoperative ERCP (PostERCP). Data Extraction and Synthesis: A frequentist random-effects network meta-analysis was performed. The surface under the cumulative ranking curve (SUCRA) was used to show the probability that each approach would be the best for each outcome. Main Outcomes and Measures: Primary outcomes were the safety to efficacy ratio using overall mortality and morbidity rates as the main indicators of safety and the success rate as an indicator of efficacy. Secondary outcomes were acute pancreatitis, biliary leak, overall bleeding, operative time, length of hospital stay, total cost, and readmission rate. Results: The 20 trials comprised 2489 patients (and 2489 procedures). Laparoscopic cholecystectomy plus IntraERCP had the highest probability of being the most successful (SUCRA, 87.2%) and safest (SUCRA, 69.7%) with respect to morbidity. All approaches had similar results regarding overall mortality. Laparoscopic cholecystectomy plus LCBDE was the most successful for avoiding overall bleeding (SUCRA, 83.3%) and for the shortest operative time (SUCRA, 90.2%) and least total cost (SUCRA, 98.9%). Laparoscopic cholecystectomy plus IntraERCP was the best approach for length of hospital stay (SUCRA, 92.7%). Inconsistency was found in operative time (indirect estimate, 19.05; 95% CI, 2.44-35.66; P = .02) and total cost (indirect estimate, 17.06; 95% CI, 3.56-107.21; P = .04). Heterogeneity was observed for success rate (τ, 0.8), operative time (τ, >1), length of stay (τ, >1), and total cost (τ, >1). Conclusions and Relevance: The combined LC and IntraERCP approach had the greatest odds to be the safest and appears to be the most successful. Laparoscopic cholecystectomy plus LBCDE appears to reduce the risk of acute pancreatitis but may be associated with a higher risk of biliary leak.

BACKGROUND: Adjuvant therapy after curative surgery for sporadic pancreatic neuroendocrine tumor (pNETs) is not currently recommended, assuming that all patients could be cured by a radical resection. The aim of our study is to establish how many and which kind of patients remained uncured after radical resection of pNET. METHODS: Retrospective study involving 143 resected sporadic pNETs. The survival analysis was carried out using the cure model, describing the cure fraction and the excess of risk recurrence. Multivariate analyses were made in order to evaluate the non negligible effect of demographics, clinical and pathological factors on survival parameters. The results were reported as percentages, fractions, ORs and HRs with 95% confidence interval (95 CI %). RESULTS: The cure fraction and the excess of hazard rate of the whole population were 57.1% (37.4-74.6, 95% CI) and 0.06 (0.03-0.07, 95% CI), respectively. Two independent factors were related to the cure fraction: TNM stage (OR 0.27⯱â¯0.17; Pâ¯=â¯0.002) and grading (OR 0.11⯱â¯0.18; Pâ¯=â¯0.004). Considering the excess of hazard rate, only two independent factors were related to an increased risk of recurrence: TNM stage (HR 3.49⯱â¯1.12; Pâ¯=â¯0.004) and grading (HR 4.93⯱â¯1.82; Pâ¯<â¯0.001). CONCLUSION: The radical surgery has a high probability of cure in stages I-II or in grading 1 while, in stages III-IV or in grading 3 tumors, surgery alone failed to achieve a "cure". A multimodal treatment should be employed in order to avoid a recurrence of the disease.

BACKGROUND: Laparoscopic distal pancreatectomy represents a difficult surgical procedure with an high conversion rate to open procedure. The factors related to its difficulty and conversion to open distal pancreatectomy were rarely reported. The aim of the present study was to identify which factors are related to conversion from laparoscopic to open distal pancreatectomy. METHODS: A retrospective study of a prospective database of 68 patients who underwent laparoscopic distal pancreatectomy was conducted at a high-volume center by pancreatic surgeons experienced with laparoscopic surgery. Pre-intra and postoperative data were collected. Patients who completed a laparoscopic distal pancreatectomy were compared with those who needed a conversion to the open approach as regard demographic, clinical, radiological, and surgical data. Univariate and multivariate analyses were carried out. RESULTS: Univariate analysis suggested that the site of the lesion, the extension of pancreatic resection, and the requirement for an extended procedure to adjacent organs were significantly associated with the risk of conversion to the open approach. Multivariate analysis showed that only the extension of the pancreatic resection (subtotal pancreatectomy) was significantly related to the odds of conversion [odds ratio (OR) 19.5; 95% confidence interval (CI) 1.1-32.3; P = 0.038]. Preoperative suspicion of malignancy differed between the two groups; however, this difference did not reach statistical significance (P = 0.078). CONCLUSIONS: Despite the limitations of the study, only the extension of pancreatic resection seemed to be the main factor related to conversion during laparoscopic distal pancreatectomy.

BACKGROUND: R status represents an important prognostic factors in periampullary cancers. Thus, it is useful to verify if it can be influenced by different techniques of margination. METHODS: Single-centre, randomised clinical trial of patients affected by periampullary cancer who underwent pancreaticoduodenectomies which included two different types of margination: arm A (multicolour inking) and arm B (monocolour inking). The primary endpoint was the overall R1 resection rate and its difference between the two arms. The secondary endpoints were the R1 resection rate in each margin and its difference between the two arms, and the impact of margin status on survival. RESULTS: Fifty patients were randomised, 41 analysed: 22 in arm A, 19 arm B. The overall R1 status was 61%, without significant differences between the two arms. The margin most commonly involved was the superior mesenteric artery (SMA) (36.6%). A trend in favour of arm B was shown for the superior mesenteric artery margin (arm Aâ¯=â¯22.7% versus arm Bâ¯=â¯52.6%; Pâ¯=â¯0.060). The anterior surface (Pâ¯=â¯0.015), SMA (Pâ¯=â¯0.047) and pancreatic remnant (Pâ¯=â¯0.018) margins significantly influenced disease-free survival. CONCLUSIONS: The R status was not influenced by different techniques of margination using a standardised pathological protocol. The SMA margin seemed to be the most important margin for evaluating both R status and disease-free survival.

BACKGROUND: Many mini-invasive pancreaticoduodenectomy (MIPD) techniques have been reported, but their advantages with respect to an open technique (OPD) and with respect to each other are unclear. METHOD: A systematic literature search of studies comparing different types of MIPD was carried out: laparoscopic-assisted (LAPD), totally robotic (TRPD), totally laparoscopic (TLPD) or totally laparoscopic-robotic assisted (TLPD-RA) to OPD. The primary endpoint was postoperative mortality. The secondary endpoints were intraoperative, postoperative and oncological outcomes. A network meta-analysis was designed to generate direct, indirect and mixed estimate effects, between different approaches, for each variable. The effects were reported as pairwise comparisons and hierarchical ranking as to each approach could be the best or the worst for each outcome, expressed by the surface under the cumulative ranking curve. RESULTS: Twenty studies were identified, involving 2759 patients: 1813 OPDs, 81 LAPDs, 505 TRPDs, 224 TLPDs and 136 TLPD-RAs. No differences regarding postoperative mortality were found in pairwise comparison. The LAPD technique had a high probability of being the worst approach, while TRPD had a high probability of being one of the best. Regarding the secondary endpoints, OPD was the best regarding operative time and postoperative bleeding, but the worst regarding blood loss and wound infection. The TRPD or TLPD-RA techniques seemed to be the best for delayed gastric emptying, length of hospital stay, harvested lymph nodes and postoperative morbidity. The TLPD technique was often the worst approach, especially for overall and major complications, postoperative bleeding and biliary leak. CONCLUSION: The safest MIPDs are those involving a robotic system which seems to have a promising role in ameliorating the outcomes of OPD, especially when compared to a laparoscopic approach.

The objective of the study was to evaluate the Fukuoka guidelines in indicating the proper management for recognising the risk factors of malignancy. Data of patients with branch duct intraductal papillary mucinous neoplasms who underwent pancreatic resection or surveillance according to the Fukuoka risk parameters were collected in a prospective database. The clinical outcome (development of pancreatic cancer, overall and disease-specific survival) and pathological results were evaluated in all patients and in resected cases, respectively. The data of 197 patients were collected: 23 primarily resected and 174 primarily followed. Of the latter, 16 were secondarily resected. Among the patients resected, 21 (53.9%) showed diagnosis of in situ or invasive carcinoma and only contrast-enhancing mural nodules were significantly related to malignancy (P = 0.002), with a DOR of 3.3 and an LH+ of 2.2. Development of pancreatic cancer was shown in ten (5.7%) of the patients primarily followed. The overall survival and disease-specific survival were similar between patients primarily followed and primarily resected. It seems reasonable to suggest that a branch duct intraductal papillary mucinous neoplasm should be treated as a benign and indolent disease that is rarely malignant. Enhancing mural nodules represent the best indicator for surgery.

BACKGROUND: In 2015, basing on objective preoperative factors related to pancreas remnant texture (body mass index, Wirsung duct size and preoperative diagnosis), we proposed a score model to predict the risk of postoperative pancreatic fistula after partial pancreatectomies. The aim of the present study was to prospectively validate this preoperative predictive risk score for postoperative pancreatic fistula after pancreaticoduodenectomy. METHODS: Prospective study of consecutive patients who underwent pancreaticoduodenectomy in which a preoperative risk score, based on factors related to the pancreatic texture, was calculated. The risk score model was tested by comparison with subjective intraoperative assessment of the pancreas remnant texture and drain amylase value on postoperative day 1. Sensitivity, specificity, positive and negative likelihood ratio and area under the curve were calculated. RESULTS: Eighty-four patients who underwent pancreaticoduodnectomy were analyzed. Clinically relevant pancreatic fistulas rate was 40.6%. The risk score model with a cut-off of 6 increased the odds of pancreatic fistula approximately 3 fold but it was not independently related to it. On the contrary, considering a cut-off of 5, the risk score model increased the odds of pancreatic fistula 11-16 fold and it was independently related to it. The new risk score model and pancreatic texture had high sensitivity (97% and 88%, respectively) and low specificity (34% and 60%, respectively) while the amylase drain value had low sensitivity (44%) and high specificity (92%). CONCLUSIONS: The preoperative risk score model with a cut-off of 5 was a useful predictor of clinically relevant pancreatic fistula after pancreaticoduodenectomy. The drain amylase value represents a complementary factor to the risk score in predicting a pancreatic fistula.

BACKGROUND: The management of small (≤20 mm), nonfunctioning pancreatic neuroendocrine neoplasms (pNENs) remains under debate. The European Neuroendocrine Tumor Society guidelines advocate the possibility of a conservative approach. METHODS: A systematic literature search was conducted to identify all studies comparing the risk of malignancy in small pNENs with respect to large ones (>20 mm). Malignancy was defined based on the presence of nodal metastases. Distant metastases, tumor grading (G2-3), vascular microscopic invasion, stage III-IV, and overall and disease-free survival also were evaluated. The data were reported in two ways: using the risk difference (RD) and the likelihood of being helped or harmed (LHH). RESULTS: The search identified only 6 eligible studies with an overall population of 1697 resected pNENs: 382 (22.5%) small and 1315 (77.5%) large. The RD of lymph nodal metastases was -0.26 (95% confidence interval (CI): -0.31 to -0.22; P < 0.001). The LHH was 0.34, suggesting that the risk of leaving a malignancy during follow-up due to the adoption of a conservative strategy was three times higher than the benefits. The risk difference of distant metastases, G3 lesions, G2-G3 lesions, stage III/IV, microscopic vascular invasion, death, and recurrence of the disease were lower in small NF-PNETs than large ones. The related LHH values suggested that a watch-and-wait policy never provided a benefit. CONCLUSIONS: Even if the malignancy rate in sporadic, small pancreatic neuroendocrine neoplasms was lower than in large ones, this difference did not justify a watch-and-wait policy.

Open adrenalectomy still plays an important role in adrenal surgery. A review of the current literature has been carried out to discuss the main indication to open adrenalectomy with regards to the main adrenal pathologies. The authors underlined the role of open adrenalectomy on the basis of personal experience and a literature review. Indication to open adrenalectomy for adrenal cysts, myelolipomas, pheochromocytomas, metastases, adrenocortical carcinomas and tumour recurrences were analysed and discussed. Open adrenalectomy has still an important role in several adrenal pathologies: it is mandatory in some specific situations, such as big lesions, risk of malignancy, emergency settings and in case of recurrent tumoral disease.

BACKGOUND: There is currently there is substantial controversy regarding the best management of non-functioning pancreatic neuroendocrine tumours ≤2 cm. METHODS: Retrospective study involving 102 surgically treated patients affected by non-functioning pancreatic neuroendocrine tumours. Patients having small tumours (≤2 cm) (Group A) and those having large tumours (>2 cm) (Group B) were compared regarding demographics, clinical and pathological factors with the aim of evaluating the risk of malignancy and survival times. RESULTS: The small tumours were T3-4 in 11% and G2-3 in 36.6% of cases; lymph node and distant metastases were present in 31% and 8% of the cases, respectively. When small and large tumours were compared, significant differences were found in relation to the presence of symptoms (P = 0.012), tumour status (P > 0.001), grading (P > 0.001) and years lost due to disability (P = 0.002). Multivariate analysis of the factors predicting malignancy and survival times showed that tumour size was related only to grading (P < 0.001). The years of life lost and disability adjusted life years were influenced by age at of diagnosis, the presence of symptoms and years lost due to disability only by grading. CONCLUSIONS: Tumour size alone did not seem to be reliable in predicting malignancy because, first, small tumours (≤2 cm) could present lymph node or distant metastases, and could be G2-3 in a non-negligible percentage of cases and second, their risk of malignancy and survival time are similar to large tumours. Additional parameters have to be considered in order to establish the proper management of small tumours, such as age at diagnosis, presence of symptoms and grading.

PURPOSE: Two main techniques are commonly used during laparoscopic right hemicolectomy in order to perform the ileocolic anastomosis: intracorporeal (IA) and extracorporeal (EA). The aim of this study was to evaluate the safety of the two techniques. METHODS: A systematic review was carried out to identify studies comparing IA and EA. The primary endpoint was anastomotic leakage. The secondary endpoints were intra- and postoperative results. A meta-analysis was carried out using the random-effects model. RESULTS: Fourteen studies matched the selection criteria, enrolling 1717 patients (50.3 % IA, 49.7 % EA). The anastomotic leakage was similar in the IA and the EA groups (3.4 vs. 4.6 %, respectively) with a risk difference (RD) of -0.01 (95 % CI = -0.03 to 0.01; P = 0.120). IA group had lower overall complication rate (27.6 vs. 38.4 %; RD = -0.15; 95 % CI = 0.27 to -0.04; P = 0.009) and wound infection rate (4.9 vs. 8.9 %; RD = 0.52; -0.03; 95 % CI = -0.06 to -0.01; P = 0.030). Time to first oral intake (weighted mean difference (WMD) = -1; 95 % CI = -1.59 to -0.41; P < 0.001), length of hospital stay (WMD = -1.13; 95 % CI = -1.90 to -0.35; P = 0.004) and minilaparotomy size (WMD = -26; 95 % CI = -38 to -13; P < 0.001) were shorter in IA patients. The incisional hernia rate was lower in the IA group (2.3 vs. 13.7 %) with an RD of -0.09 (95 % CI = -0.17 to -0.02; P = 0.020). There were no differences in operative time, blood loss, conversion, internal hernia, reoperation, mortality, time to first flatus and defecation, analgesic required, number of lymph nodes harvested and length of distal margin. CONCLUSIONS: Laparoscopic right hemicolectomy with IA is a safe alternative to EA. Additional well-structured, prospective randomised trials are needed to confirm all the advantages regarding postoperative results which were pointed out in our study.

OBJECTIVES: This study aimed to evaluate the accuracy of the risk factors proposed by Fukuoka guidelines in detecting malignancy of branch-duct intraductal papillary mucinous neoplasms. METHOD: Diagnostic meta-analysis of cohort studies. A systematic literature search was conducted using MEDLINE, the Cochrane Library, Scopus, and the ISI-Web of Science databases to identify all studies published up to 2014. RESULTS: Twenty-five studies (2025 patients) were suitable for the meta-analysis. The "high risk stigmata" showed the highest pooled diagnostic odds ratio (jaundice, 6.3; positive citology, 5.5; mural nodules, 4.8) together with 2 "worrisome features" (thickened/enhancing walls, 4.2; duct dilatation, 4.0) and 1 "other parameters" (carbohydrate antigen 19-9 serum levels, 4.6). CONCLUSIONS: An "ideal risk factor" capable of recognizing all malignant branch-duct intraductal papillary mucinous neoplasms was not identified and some "dismal areas" remain. However, "high risk stigmata" were strongly related to malignancy, mainly enhancing mural nodules. Among the "worrisome features," duct dilatation and thickened/enhancing walls were underestimated, and their diagnostic performance was similar to those of "high risk stigmata." The carbohydrate antigen 19-9 serum level should be added to the Fukuoka algorithm because this value could help in carrying out correct management.

In recent years, an increasing of the level of evidence occurred with a significant number of meta-analyses. A question remains open: can LDP be considered the "new gold standard" for benign and malignant body-tail pancreatic disease? A systematic literature search was conducted to identify all meta-analyses published up to 2016. The primary endpoint was to evaluate the clinical safety of LDP. The secondary endpoints were to evaluate: the length of hospital stay (LOS), readmission rate, postoperative pancreatic fistula (POPF), overall postoperative morbidity and oncologic safety. Nine studies were found to be suitable for the analysis. Data regarding clinical safety were extractable in all meta-analyses but a "between study" homogeneity was available only in 7. The safety of LDP was sustained by six meta-analyses in benign/low grade of malignancy body-tail pancreatic lesions, by one in ductal adenocarcinoma (PDAC). LDP has a shorter LOS compared to open distal pancreatectomy (ODP), demonstrated by three meta-analyses. Readmission rate in LDP procedures was lower than in ODP; these data are sustained by one meta-analysis. LDP is not inferior to ODP regarding the occurrence of POPF (seven meta-analyses); overall morbidity rate was lower in LDP than ODP for benign or low-grade malignant tumor. The use of the LDP in PDAC is sustained from one study. In conclusion, LDP can be considered a safe alternative to ODP. LDP could have some advantages but the data do not permit to define this procedure as the first choice or as the new gold standard.

BACKGROUND: Total pancreatectomy is actually considered a viable option in selected patients even if large comparative studies between partial versus total pancreatectomy are not currently available. Our aim was to evaluate whether total pancreatectomy can be considered as feasible, safe, efficacious, and cost-effective as pancreaticoduodenectomy. METHODS: A single center, prospective, observational trial, regarding postoperative outcomes, long-term results, and cost-effectiveness, in a tertiary referral center was conducted, comparing consecutive patients who underwent elective total pancreatectomy and/or pancreaticoduodenectomy. RESULTS: Seventy-three consecutive elective total pancreatectomies and 184 pancreaticoduodenectomies were compared. There were no significant differences regarding postoperative outcomes and overall survival. The quality of life, evaluated in 119 patients according to the EQ-5D-5L questionnaire, showed that there were no significant differences regarding the five items considered. The mean EQ-5D-5L score was similar in the two procedures (total pancreatectomy = 0.872, range 0.345-1.000; pancreaticoduodenectomy = 0.832, range 0.393-1.000; P = 0.320). The impact of diabetes according to the Problem Areas in Diabetes (PAID) questionnaire did not show any significant differences except for question 13 (total pancreatectomy = 0.60; pancreaticoduodenectomy = 0.19; P = 0.022). The cost-effectiveness analysis suggested that the quality-adjusted life year was not significantly different between the two procedures (total pancreatectomy = 0.910, range 0.345-1.000; pancreaticoduodenectomy = 0.910, range -0.393-1.000; P = 0.320). CONCLUSIONS: From this study, it seems reasonable to suggest that total pancreatectomy can be considered as safe, feasible, and efficacious as PD and acceptable in terms of cost-effectiveness.
