Clinical and Financial Validation of the International Study Group for Pancreatic Surgery (ISGPS) Definition of Post-Pancreatectomy Acute Pancreatitis (PPAP): International Multicenter Prospective Study.

OBJECTIVE: To validate the ISGPS definition and grading system of PPAP after pancreatoduodenectomy (PD). SUMMARY BACKGROUND DATA: In 2022, the International Study Group for Pancreatic Surgery (ISGPS) defined post-pancreatectomy acute pancreatitis (PPAP) and recommended a prospective validation of its diagnostic criteria and grading system. METHODS: This was a prospective, international, multicenter study including patients undergoing PD at 17 referral pancreatic centers across Europe, Asia, Oceania, and the United States. PPAP diagnosis required the following three parameters: (1) postoperative serum hyperamylasemia /hyperlipasemia (POH) persisting on postoperative days 1 and 2, (2) radiologic alterations consistent with PPAP, and (3) a clinically relevant deterioration in the patient's condition. To validate the grading system, clinical and economic parameters were analyzed across all grades. RESULTS: Among 2902 patients undergoing PD, 7.5% (n=218) developed PPAP (6.3% grade B and 1.2% grade C). POH occurred in 24.1% of patients. Hospital stay was associated with PPAP grades (No POH/PPAP 10 days (IQR 7-17) days, grade B 22 days (IQR 15-34) days, and grade C 43 days (IQR 27-54) days; P<0.001), as well as intensive care unit admission (No POH/PPAP 5.4%, grade B 12.6%, grade C 82.9%; P<0.010), and hospital readmission rates (No POH/PPAP 7.3%, grade B 16.1%, grade C 18.5%; P<0.05). Costs of grade B and C PPAP were 2 and 11 times greater than uncomplicated clinical course, resp. (P<0.001). CONCLUSIONS: This first prospective, international validation study of the ISGPS definition and grading system for PPAP highlighted the relevant clinical and financial implications of this condition. These results stress the importance of routine screening for PPAP in patients undergoing PD.

Postpancreatectomy Acute Pancreatitis (PPAP): Definition and Grading From the International Study Group for Pancreatic Surgery (ISGPS).

OBJECTIVE: The ISGPS aimed to develop a universally accepted definition for PPAP for standardized reporting and outcome comparison. BACKGROUND: PPAP is an increasingly recognized complication after partial pancreatic resections, but its incidence and clinical impact, and even its existence are variable because an internationally accepted consensus definition and grading system are lacking. METHODS: The ISGPS developed a consensus definition and grading of PPAP with its members after an evidence review and after a series of discussions and multiple revisions from April 2020 to May 2021. RESULTS: We defined PPAP as an acute inflammatory condition of the pancreatic remnant beginning within the first 3 postoperative days after a partial pancreatic resection. The diagnosis requires (1) a sustained postoperative serum hyperamylasemia (POH) greater than the institutional upper limit of normal for at least the first 48 hours postoperatively, (2) associated with clinically relevant features, and (3) radiologic alterations consistent with PPAP. Three different PPAP grades were defined based on the clinical impact: (1) grade postoperative hyperamylasemia, biochemical changes only; (2) grade B, mild or moderate complications; and (3) grade C, severe life-threatening complications. DISCUSSIONS: The present definition and grading scale of PPAP, based on biochemical, radiologic, and clinical criteria, are instrumental for a better understanding of PPAP and the spectrum of postoperative complications related to this emerging entity. The current terminology will serve as a reference point for standard assessment and lend itself to developing specific treatments and prevention strategies.

Rectal Cancer in Adolescent and Young Adult Patients: Pattern of Clinical Presentation and Case-Matched Comparison of Outcomes.

BACKGROUND: Rectal cancer in adolescents and young adults (age ≤39) is increasing. Early diagnosis is a challenge in this subset of patients. OBJECTIVE: This study aims to analyze the presentation pattern and outcomes of sporadic rectal cancer in adolescents and young adults. DESIGN: This is a retrospective study. SETTING: This study was conducted at 3 European tertiary centers. PATIENTS: Data on adolescents and young adults operated on for sporadic rectal cancer (January 2008 through October 2019) were analyzed. To compare outcomes, adolescents and young adults were matched to a group of patients aged ≥40 operated on during the same period. MAIN OUTCOME MEASURES: The primary outcomes measured were clinical presentation and long-term outcomes. RESULTS: Sporadic rectal cancers occurred in 101 adolescents and young adults (2.4%; mean age, 33.5; range, 18-39); 51.5% were male, and a smoking habit was reported by 17.8% of patients. The rate of a family history for colorectal cancer was 25.7%, and of these patients, 24.7% were obese. Diagnosis based on symptoms was reported in 92.1% patients, and the mean time from first symptoms to diagnosis was 13.7 months. The most common symptom at diagnosis was rectal bleeding (68.8%), and 12% and 34% of the adolescents and young adults presented with locally advanced or metastatic disease at diagnosis. Consequently, 68.3% and 62.4% adolescents and young adults received neoadjuvant and adjuvant treatments. The rate of complete pathological response was 24.1%; whereas 38.6% patients had stage IV disease, and 93.1% were microsatellite stable. At a mean follow-up of 5 years, no difference in cancer-specific survival, but a lower disease-free survival was reported in adolescents and young adults (p < 0.0001) vs the matched group. Adolescents and young adults with stages I to II disease had shorter cancer-specific survival and disease-free survival (p = 0.006; p < 0.0001); with stage III disease, they had a shorter disease-free survival (p = 0.01). LIMITATIONS: This study was limited by its observational, retrospective design. CONCLUSIONS: The significantly delayed diagnosis in adolescents and young adults may have contributed to the advanced disease at presentation and lower disease-free survival, even at earlier stages, suggesting a higher metastatic potential than in older patients.

El diagnóstico con base en los síntomas se informó en el 92,1% de los pacientes, el tiempo promedio desde los primeros síntomas hasta el diagnóstico fue de 13,7 meses. El síntoma más común en el momento del diagnóstico fue el sangrado rectal (68,8%). 12% y 34% de adolescentes y adultos jóvenes presentaron enfermedad localmente avanzada o metastásica en el momento del diagnóstico. Por lo tanto, el 68,3% y el 62,4% de adolescentes y adultos jóvenes recibieron neoadyuvancia y adyuvancia. La tasa de respuesta patológica completa fue del 24,1%; mientras que el 38,6% estaban en estadio IV. El 93,1% eran microsatelite estable. Con una media de seguimiento de 5 años, no se observaron diferencias en la sobrevida específica del cáncer, pero se informó una menor sobrevida libre de enfermedad en adolescentes y adultos jóvenes (p <0,0001) frente al grupo emparejado. Los adolescentes y adultos jóvenes en estadios I-II tuvieron una sobrevida específica por cáncer y una sobrevida libre de enfermedad más corta (p = 0,006; p <0,0001); el estadio III tuvo una sobrevida libre de enfermedad más baja (p = 0,01).LIMITACIONES:Diseño observacional y retrospectivo.CONCLUSIONES:El diagnóstico notablemente demorado en adolescentes y adultos jóvenes puede contribuir a la presentación de una enfermedad avanzada y a una menor sobrevida libre de enfermedad, incluso en estadios más tempranas, lo cual implica un mayor potencial metastásico en comparación con pacientes mayores.

A Snapshot of Elective Oncological Surgery in Italy During COVID-19 Emergency: Pearls, Pitfalls, and Perspectives.

OBJECTIVE: To analyze the impact of COVID-19 emergency on elective oncological surgical activity in Italy. SUMMARY OF BACKGROUND DATA: COVID-19 emergency shocked national health systems, subtracting resources from treatment of other diseases. Its impact on surgical oncology is still to elucidate. METHODS: A 56-question survey regarding the oncological surgical activity in Italy during the COVID-19 emergency was sent to referral centers for hepato-bilio-pancreatic, colorectal, esophago-gastric, and sarcoma/soft-tissue tumors. The survey portrays the situation 5 weeks after the first case of secondary transmission in Italy. RESULTS: In total, 54 surgical Units in 36 Hospitals completed the survey (95%). After COVID-19 emergency, 70% of Units had reduction of hospital beds (median -50%) and 76% of surgical activity (median -50%). The number of surgical procedures decreased: 3.8 (interquartile range 2.7-5.4) per week before the emergency versus 2.6 (22-4.4) after (P = 0.036). In Lombardy, the most involved district, the number decreased from 3.9 to 2 procedures per week. The time interval between multidisciplinary discussion and surgery more than doubled: 7 (6-10) versus 3 (3-4) weeks (P < 0.001). Two-third (n = 34) of departments had repeated multidisciplinary discussion of patients. The commonest criteria to prioritize surgery were tumor biology (80%), time interval from neoadjuvant therapy (61%), risk of becoming unresectable (57%), and tumor-related symptoms (52%). Oncological hub-and-spoke program was planned in 29 departments, but was active only in 10 (19%). CONCLUSIONS: This survey showed how surgical oncology suffered remarkable reduction of the activity resulting in doubled waiting-list. The oncological hub-and-spoke program did not work adequately. The reassessment of healthcare systems to better protect the oncological path seems a priority.

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.

Perioperative Interstitial Fluid Expansion Predicts Major Morbidity Following Pancreatic Surgery: Appraisal by Bioimpedance Vector Analysis.

OBJECTIVE: To evaluate whether perioperative bioimpedance vector analysis (BIVA) predicts the occurrence of surgery-related morbidity. SUMMARY BACKGROUND DATA: BIVA is a reliable tool to assess hydration status and compartimentalized fluid distribution. METHODS: The BIVA of patients undergoing resection for pancreatic malignancies was prospectively measured on the day prior to surgery and on postoperative day (POD)1. Postoperative morbidity was scored per the Clavien-Dindo classification (CDC), and the Comprehensive Complication Index (CCI). RESULTS: Out of 249 patients, the overall and major complication rates were 61% and 16.5% respectively. The median CCI was 24 (IQR 0.0-24.2), and 24 patients (9.6%) had a complication burden with CCI≥40. At baseline the impedance vectors of severe complicated patients were shorter compared to the vectors of uncomplicated patients only for the female subgroup (P=0.016). The preoperative extracellular water (ECW) was significantly higher in patients who experienced severe morbidity according to the CDC or not [19.4L (17.5-22.0) vs. 18.2L (15.6-20.6), P=0.009, respectively] and CCI≥40, or not [20.3L (18.5-22.7) vs. 18.3L (15.6-20.6), P=0.002, respectively]. The hydration index on POD1 was significantly higher in patients who experienced major complications than in uncomplicated patients (P=0.020 and P=0.025 for CDC and CCI, respectively).At a linear regression model, age (ß=0.14, P=0.035), sex female (ß=0.40, P<0.001), BMI (ß=0.30, P<0.001), and malnutrition (ß=0.14, P=0.037) were independent predictors of postoperative ECW. CONCLUSION: The amount of extracellular fluid accumulation predicts major morbidity after pancreatic surgery. Female, obese and malnourished patients were at high risk of extracellular fluid accumulation.

Minimally Invasive versus Open Distal Pancreatectomy for Ductal Adenocarcinoma (DIPLOMA): A Pan-European Propensity Score Matched Study.

OBJECTIVE: The aim of this study was to compare oncological outcomes after minimally invasive distal pancreatectomy (MIDP) with open distal pancreatectomy (ODP) in patients with pancreatic ductal adenocarcinoma (PDAC). BACKGROUND: Cohort studies have suggested superior short-term outcomes of MIDP vs. ODP. Recent international surveys, however, revealed that surgeons have concerns about the oncological outcomes of MIDP for PDAC. METHODS: This is a pan-European propensity score matched study including patients who underwent MIDP (laparoscopic or robot-assisted) or ODP for PDAC between January 1, 2007 and July 1, 2015. MIDP patients were matched to ODP patients in a 1:1 ratio. Main outcomes were radical (R0) resection, lymph node retrieval, and survival. RESULTS: In total, 1212 patients were included from 34 centers in 11 countries. Of 356 (29%) MIDP patients, 340 could be matched. After matching, the MIDP conversion rate was 19% (n = 62). Median blood loss [200 mL (60-400) vs 300 mL (150-500), P = 0.001] and hospital stay [8 (6-12) vs 9 (7-14) days, P < 0.001] were lower after MIDP. Clavien-Dindo grade ≥3 complications (18% vs 21%, P = 0.431) and 90-day mortality (2% vs 3%, P > 0.99) were comparable for MIDP and ODP, respectively. R0 resection rate was higher (67% vs 58%, P = 0.019), whereas Gerota's fascia resection (31% vs 60%, P < 0.001) and lymph node retrieval [14 (8-22) vs 22 (14-31), P < 0.001] were lower after MIDP. Median overall survival was 28 [95% confidence interval (CI), 22-34] versus 31 (95% CI, 26-36) months (P = 0.929). CONCLUSIONS: Comparable survival was seen after MIDP and ODP for PDAC, but the opposing differences in R0 resection rate, resection of Gerota's fascia, and lymph node retrieval strengthen the need for a randomized trial to confirm the oncological safety of MIDP.

The evolution of post-operative pancreatic fistula (POPF) classification: A single-center experience.

BACKGROUND: The ISGPS classification of post-operative pancreatic fistula (POPF) was recently revised, introducing the concept of biochemical leak (BL) which replaced grade A POPF. More recently, an additional distinction on three different subclasses for grade B (B1-B3) POPF was proposed. The aim of this study was to evaluate the impact of these modifications in clinical practice. METHODS: All pancreatico-duodenectomies (PD) and distal pancreatectomies (DP) performed between 2010 and 2016 were retrospectively evaluated. Incidence and grade of POPF using the old and new ISGPS classification were evaluated. Three grade B subclasses (B1: maintenance of abdominal drain >3 weeks; B2: adoption of specific medical treatments for POPF; B3: use of radiological procedures) were evaluated for clinical severity. RESULTS: A total of 716 patients (502 PD, 214 DP) were evaluated. The new ISGPS classification reduced the reported rate of POPF (30.7% vs 35.2% for PD, p > 0.05; 28% vs 44.9% for DP, p < 0.05), due to the abolition of grade A POPF. Grade B1, B2 and B3 rates were 3.1%, 73.8% and 23.1% in PD and 12.3%, 47.4% and 40.3% in DP, respectively. Passing from B1 to B3, significant increases in wound infection (0-40%), mean length of stay in PD (14.7-22.5 days; p < 0.05) and readmission rate in DP (0-39.1%) were observed. CONCLUSIONS: The new ISGPS classification significantly reduces the reported rate of POPF, particularly after DP. The three different grade B subclasses (B1-B3) better discriminate the severity of post-operative course, especially after PD.

Preoperative Biliary Stenting and Major Morbidity After Pancreatoduodenectomy: Does Elapsed Time Matter?: The FRAGERITA Study Group.

OBJECTIVE: To analyze possible associations between the duration of stent placement before surgery and the occurrence and severity of postoperative complications after pancreatoduodenectomy (PD). BACKGROUND: The effect of preoperative stent duration on postoperative outcomes after PD has not been investigated. METHODS: From 2013 to 2016, patients who underwent PD for any reasons after biliary stent placement at 5 European academic centers were analyzed from prospectively maintained databases. The primary aim was to investigate the association between the duration of preoperative biliary stenting and postoperative morbidity. Patients were stratified by stent duration into 3 groups: short (<4 weeks), intermediate (4-8 weeks), and long (≥8 weeks). RESULTS: In all, 312 patients were analyzed. The median time from stent placement to surgery was 37 days (2-559 days), and most operations were performed for pancreatic cancer (67.6%). Morbidity and mortality rates were 56.0% and 2.6%, respectively. Patients in the short group (n = 106) experienced a higher rate of major morbidity (43.4% vs 20.0% vs 24.2%; P < 0.001), biliary fistulae (13.2% vs 4.3% vs 5.5%; P = 0.031), and length of hospital stay [16 (10-52) days vs 12 (8-35) days vs 12 (8-43) days; P = 0.025]. A multivariate adjusted model identified the short stent duration as an independent risk factor for major complications (odds ratio 2.64, 95% confidence interval 1.23-5.67, P = 0.013). CONCLUSIONS: When jaundice treatment cannot be avoided, delaying surgery up to 1 month after biliary stenting may reduce major morbidity, procedure-related complications, and length of hospital stay.

First experience in colorectal surgery with a new robotic platform with haptic feedback.

The use of robotic techniques is increasing in colorectal surgery. Recently, the Senhance™ surgical robotic system was introduced as a novel robotic platform designed to overcome some of the limits of standard laparoscopy. This study describes the initial, single center experience, evaluating feasibility and safety of the new robotic system in performing colorectal surgical procedures. METHODS: From June 2015 to November 2016, perioperative data of the first 45 patients who underwent robotic colorectal surgery with the SenhanceTM surgical robotic system were collected and analyzed. Indications for surgery included inflammatory bowel disease, colorectal cancer, endoscopically unresectable adenomas and complicated diverticular disease. RESULTS: The median age was 57 years (18-92) and the median BMI was 24 Kg/m2 (16-30). Surgical indications were colorectal cancer (66%), complicated inflammatory bowel disease (18%), diverticular disease (11%) and endoscopically unresectable adenoma (4.4%). The median operative time was 256 minutes; the median docking time 10.7 min (range 2-25). There were 3 conversions to standard laparoscopy, and none to laparotomy. All patients operated on for malignancy (28 adenocarcinoma, 2 neuroendocrine tumors) underwent an appropriate oncological procedure. The median time to discharge was 5 days (range 3-19). The incidence of post-operative complications was 35.5% (Clavien-Dindo I/II-14 patients, III-2 patients). One patient was readmitted in the postoperative period. No patient required reoperation. CONCLUSION: The results of this audit suggest that adoption of The Senhance™ surgical robotic system in colorectal surgery is feasible and safe. More clinical data are needed to determine whether this approach can offer any other benefits over other minimally invasive surgical techniques. This article is protected by copyright.

Role of preoperative biliary stents, bile contamination and antibiotic prophylaxis in surgical site infections after pancreaticoduodenectomy.

BACKGROUND: The routine use of preoperative biliary drainage before pancreaticoduodenectomy (PD) remains controversial. This observational retrospective study compared stented and non-stented patients undergoing PD to assess any differences in post-operative morbidity and mortality. METHODS: A total of 180 consecutive patients who underwent PD and had intra-operative bile cultures performed between January 2010 and February 2013 were retrospectively identified. All patients received peri-operative intravenous antibiotic prophylaxis, primarily cefazolin. RESULTS: Overall incidence of post-operative surgical complications was 52.3 %, with no difference between stented and non-stented patients (53.4 % vs. 51.1 %; p = 0.875). However, stented patients had a significantly higher incidence of deep incisional surgical site infections (SSIs) (p = 0.038). In multivariate analysis, biliary stenting was confirmed as a risk factor for deep incisional SSIs (p = 0.044). Significant associations were also observed for cardiac disease (p = 0.010) and BMI ≥25 kg/m(2) (p = 0.045). Enterococcus spp. were the most frequent bacterial isolates in bile (74.5 %) and in drain fluid (69.1 %). In antimicrobial susceptibilty testing, all Enterococci isolates were cefazolin-resistant. CONCLUSION: Given the increased risk of deep incisional SSIs, preoperative biliary stenting in patients underging PD should be used only in selected patients. In stented patients, an antibiotic with anti-enterococcal activity should be chosen for PD prophylaxis.

Role of C-Reactive Protein Assessment as Early Predictor of Surgical Site Infections Development after Pancreaticoduodenectomy.

BACKGROUND: Surgical site infections (SSIs) are extremely common in pancreatic surgery and explain its considerable morbidity and mortality, even in tertiary centers. Early detection of these complications, with the help of laboratory assays, improve clinical outcome. The aim of the present study is to evaluate C-reactive protein (CRP) diagnostic accuracy as early predictor of SSIs after pancreaticoduodenectomy (PD). METHODOLOGY: We considered 251 consecutive PD. We prospectively recorded preoperative clinical and anthropometric data, intraoperative details and the postoperative outcome. In the first pool of consecutive patients (n = 150), we analyzed CRP levels from postoperative day 1 to 7 and investigated the prediction of SSIs. We then validated the diagnostic accuracy on the following 101 consecutive cases. RESULTS: At multivariate analysis, high BMI and preoperative biliary stenting appeared to be independently associated with SSIs and organ-space SSI development. The CRP cutoff of 17.27 mg/dl on postoperative day 3 (78% sensitivity, 79% specificity) and of 14.72 mg/dl on postoperative day 4 (87% sensitivity, 82% specificity) was in a position to predict the course of 78.2 and 80.2% of patients, respectively. CONCLUSIONS: CRP on postoperative days 3 and 4 seems able to predict postoperative course, selecting patients deserving intensification of diagnostic assessment; patients not satisfying these conditions could be reasonably directed toward early discharge.

European experience of 573 liver resections for hepatocellular adenoma: a cross-sectional study by the AFC-HCA-2013 study group.

BACKGROUND: Hepatocellular adenoma (HCA) is a benign hepatic lesion that may be complicated by bleeding and malignant transformation. The aim of the present study is to report on large series of liver resections for HCA and assess the incidence of hemorrhage and malignant transformation. METHODS: A retrospective cross-sectional study, from 27 European high-volume HPB units. RESULTS: 573 patients were analyzed. The female: male gender ratio was 8:2, mean age: 37 ± 10 years. Of the 84 (14%) patients whose initial presentation was hemorrhagic shock (Hemorrhagic HCAs), hemostatic intervention was urgently required in 25 (30%) patients. No patients died after intervention. Tumor size was >5 cm in 74% in hemorrhagic HCAs and 64% in non-hemorrhagic HCAs (p < 0.001). In non-hemorrhagic HCAs (n = 489), 5% presented with malignant transformation. Male status and tumor size >10 cm were the two predictive factors. Liver resections included major hepatectomy in 25% and a laparoscopic approach in 37% of the patients. In non-hemorrhagic HCAs, there was no mortality and major complications occurred in 9% of patients. DISCUSSION: Liver resection for HCA is safe. Presentation with hemorrhage was associated with larger tumor size. In males with a HCA >10 cm, a HCC should be suspected. In such situation, a preoperative biopsy is preferable and an oncological liver resection should be considered.

Effects of Art on Surgical Patients: A Systematic Review and Meta-analysis.

OBJECTIVES: The aim of the study was to assess the effect of art including ambient features such as music, interior design including visual art, and architectural features on health outcomes in surgical patients. BACKGROUND: Healing environments can have a positive influence on many patients, but data focusing on art in surgical patients remain scarce. METHODS: We conducted a systematic search following the PRISMA guidelines from January 2000 to October 2014 on art in surgical patients. For music interventions, we pooled controlled studies measuring health outcomes (eg, pain, anxiety, blood pressure, and heart rate) in a meta-analysis. For other art forms (ambient and architectural features and interior design), we did a narrative review, also including nonsurgical patients, and looked for examples covering 3 countries. RESULTS: Our search identified 1101 hits with 48 studies focusing on art in surgical patients: 47 studies on musical intervention and 1 on sunlight. The meta-analysis of these studies disclosed significant effects for music on pain after surgery, anxiety, systolic blood pressure, and heart rate, when compared with control groups without music. Effects of music were larger with self-selected music, and lower in surgical interventions performed under general anesthesia. Interior design features such as nature images and more spacious rooms, and architectural features providing more sunlight had positive effects on anxiety and postoperative pain. CONCLUSIONS: Self-selected music for surgical patients is an effective and low-cost intervention to enhance well being and possibly faster recovery. Although potentially very important, the impact of environmental features and spacious architecture with wide access to sunlight remains poorly explored in surgery. Further experimental research is needed to better assess the magnitude of the impact and cost effectiveness.

Laparoscopic colonic resection for splenic flexure cancer: our experience.

BACKGROUND: The treatment of colon cancer located in splenic flexure is not standardized. Laparoscopic approach is still considered a challenging procedure. This study reviews two Institutions experience in laparoscopic treatment of left colonic flexure cancer. Intraoperative, pathologic and postoperative data from patients undergoing laparoscopic splenic flexure resection were analyzed to assess oncological safety as well as early and medium-term outcomes. METHODS: From October 2005 to May 2014 laparoscopic splenic flexure resection was performed in 23 patients. RESULTS: Conversion rate was nihil. In 7 cases the anastomosis was performed intracorporeally. Specimen mean length was 21.2 cm, while the distance of distal and proximal resection margin from tumor site was 6.5 and 11.5 respectively. The mean number of harvested lymph nodes was 20.8. Mean operative time was 190 min and mean estimated blood loss was equal to 55 ml. As regard major postoperative complications, one case of postoperative acute pancreatitis and one case of postoperative bleeding from the anastomotic suture line were reported. CONCLUSIONS: Although our experience is limited and appropriate indications must be set by future randomized studies, we believe that laparoscopic resection with intracorporeal anastomosis appears feasible and safe for patients affected by splenic flexure cancer.

A partnership model between high- and low-volume hospitals to improve results in hepatobiliary pancreatic surgery.

OBJECTIVE: To optimize the results of low-volume (LV) centers for hepatopancreaticobiliary (HPB) surgery. BACKGROUND: High-volume (HV) centers for HPB surgery have lower mortality than LV. Strategies for collaboration between HV and LV centers are not well investigated. METHODS: Postoperative outcomes of patients undergoing curative HPB resection were evaluated at an LV hospital before (2006-2008) and during the collaboration (2009-2012) and at 2 hospitals with HV for either liver or pancreatic resection (2009-2012). Itinerant tutor surgeons from the HV centers were involved in the pre-, intra- and postoperative course of HPB patients at the LV hospital. RESULTS: HPB cases at the LV center increased from 18 to 40 patients per year from 2006 to 2012, whereas 6-month postoperative mortality decreased from 17.8% (2006-2008) to 6% (2009-2012), P<0.05 (liver: 10.3% vs 4.7% and pancreas: 29.4% vs 7.9%). During the collaborative study period, outcomes for hepatectomy were similar for LV and HV (85 vs 507 cases): postoperative Clavien-Dindo scores 4 and 5 were 2% and 0.2% for HV versus 2.4% and 1.2% for LV, respectively. Outcomes for pancreatic procedures (LV 63 vs HV 269 cases) showed better postoperative Clavien-Dindo scores 4 and 5 in the HV (0.7% score 4 and 1.5% score 5 for HV vs 3.2% and 6.3%, respectively, for LV) but the difference disappeared in the last 2 years (2011-2012) and matching the cases. CONCLUSIONS: Our partnership model helped improve postoperative outcomes at the LV center. Results at the LV hospital were comparable with the HV centers, although 2 years of partnership were required to achieve this in pancreatic surgery.

Preoperative Pancreatic Resection (PREPARE) score: a prospective multicenter-based morbidity risk score.

OBJECTIVES: Development of a simple preoperative risk score to predict morbidity related to pancreatic surgery. BACKGROUND: Pancreatic surgery is standardized with little technical diversity among institutions and unchanging morbidity and mortality rates in recent years. Preoperative identification of high-risk patients is potentially one of the rare avenues for improving the clinical course of patients undergoing pancreatic surgery. METHODS: Using a prospectively collected multicenter database of patients undergoing pancreatic surgery (n=703), surgical complications were classified according to the Clavien-Dindo classification. A new scoring system for preoperative identification of high-risk patients that included only objective preoperatively assessable variables was developed using a multivariate regression model. Subsequently, this scoring system was prospectively validated from 2011 to 2013 (n=429) in a multicenter setting. RESULTS: Eight independent preoperatively assessable variables were identified and included in the scoring system: systolic blood pressure, heart rate, hemoglobin level, albumin level, ASA (American Society of Anesthesiologists) score, surgical procedure, elective surgery or not, and disease of pancreatic origin or not. On the basis of 3 subgroups (low risk, intermediate risk, high risk), the proposed scoring system reached an accuracy of 75% for correctly predicting occurrence or nonoccurrence of major surgical complications in 80% of all analyzed patients within the validation cohort (c-statistic index=0.709, P<0.001, 95% confidence interval=0.657-0.760). CONCLUSIONS: We present an easily applied scoring system with convincing accuracy for identifying low-risk and high-risk patients. In contrast to other systems, the score is exclusively based on objective preoperatively assessable characteristics and can be rapidly and easily calculated.

Refractory distal ulcerative colitis: is proctocolectomy always necessary?

Refractory distal ulcerative colitis (RDUC) is defined as persistence of symptoms caused by endoscopically proven colonic inflammation located at the rectum or left colon despite oral/topical steroids and 5-ASA. RDUC affects a small subset of patients and is associated with chronic disabling symptoms and increased social/medical costs. Moreover, patients with long-standing ulcerative colitis (UC) carry an elevated risk of developing colorectal cancer and colonic mucosa high-grade dysplasia. Alternative medical strategies in steroid refractory disease are unlikely to provide durable remission in all patients, carry potential severe side effects and, as immunosuppressants, the risk of other neoplasms, and may increase the short-term complication rate when surgery is finally required. Restorative proctocolectomy with ileal pouch-anal anastomosis (RP-IPAA) allows the complete removal of the diseased rectum and colon, virtually eliminating the risk of malignant transformation and reestablishing intestinal continuity with continence preservation. Since the introduction of this surgical procedure, morbidity and mortality rates have been drastically reduced. Despite the still notable rate of surgical complications, long-term quality of life assessment has shown excellent results in nearly all patients who have undergone RP-IPAA, comparing well with the general population. Furthermore, when performed for distal UC, RP-IPAA produces similar surgical outcomes with respect to pancolitis. In conclusion, RP-IPAA should always be considered in patients with RDUC, and multidisciplinary counseling should provide patients clear information about the advantages of surgery and possible complications as well as the chance to achieve disease remission with medical therapy.
