Role of laparoscopic surgery in managing hemodynamically stable abdominal trauma patients: a single level I trauma center, propensity score matching study.

The role of laparoscopy in the treatment and diagnosis of penetrating thoraco-abdominal injury has been established. However, there is no clear consensus on the role of laparoscopy in blunt injury due to numerous reasons, such as concerns of missed injury and technical problems in treating various abdominal organs. This study aimed to determine the feasibility of laparoscopy and evaluate its safety in managing blunt and penetrating abdominal trauma. The medical records and Korean Trauma Data Base (KTDB) of patients who underwent abdominal surgery from January 2018 to December 2022 at a single level I center were collected. Patients were classified into a laparoscopy group and a laparotomy group. The laparoscopy groups were matched 1:1 with the laparotomy group by using propensity score matching (PSM). Patient demographics, injured organ and its grade, operative procedure, and postoperative outcomes were evaluated and compared between the two groups. After propensity score matching, 128 patients were included. There was no significant imbalance in demographics between the two groups except sex. Injured organ and its grade showed no significant differences between the two groups except for the incidence of omentum. Small bowel and mesenteric repair were performed most often in both groups. Splenectomy, pancreatic surgery, duodenectomy, and liver resection were performed exclusively in the laparotomy group. Severe postoperative complication rate (3% vs. 20%: p = 0.004), length of stay in ICU (3.3 ± 3.2 days vs. 4.6 ± 3.7; p = 0.046), and operation time (93.9 ± 47.7min vs. 112.8 ± 57.7; p = 0.046) were significantly lower in the laparoscopy group. The conversion rate was about 16%. There was no missed injury. In hemodynamically stable abdominal trauma patients who sustained penetrating or blunt injury, laparoscopy is feasible and safe as a diagnostic and therapeutic modality in selected cohort of abdominal trauma.

Retrospective study on the feasibility and safety of laparoscopic surgery for complicated fistulizing diverticular disease in a high-volume colorectal center.

We assessed feasibility and safety of laparoscopic sigmoidectomy for complicated fistulizing diverticular disease in a tertiary care colorectal center. A single-center retrospective study of patients undergoing sigmoidectomy for fistulizing diverticular disease between 2011 and 2021 was realized. Primary outcomes were rates of conversion to open surgery and severe postoperative morbidity at 30 days. Secondary outcomes included rates of postoperative bladder leaks on cystogram. Among the 104 patients, 32.7% had previous laparotomy. Laparoscopy was the initial approach in 103 (99.0%), with 6 (5.8%) conversions to laparotomy. Clavien-Dindo grade ≥ III complication rate at 30 days was 10.6%, including two (1.9%) anastomotic leaks. The median postoperative length of stay was 4.0 days. Seven (6.7%) patients underwent reoperation, six (5.8%) were readmitted, and one (0.9%) died within 30 days. Twelve (11.5%) ileostomies were created initially, and two (1.9%) were created following anastomotic leaks. At last follow-up, 101 (97.1%) patients were stoma-free. Urgent surgeries had a higher rate of severe postoperative complications. Among colovesical fistula patients (n = 73), postoperative cystograms were performed in 56.2%, identifying two out of the three bladder leaks detected on closed suction drains. No differences in postoperative outcomes occurred between groups with and without postoperative cystograms, including Foley catheter removal within seven days (73.2% vs. 90.6%, p = 0.08). Laparoscopic surgery for complicated fistulizing diverticulitis showed low rates of severe complications, conversions to open surgery and permanent stomas in high-volume colorectal center.

Risk Factors for Complications and Disease Recurrence after Ileocecal Resection for Crohn's Disease in Children and Adults.

This study reports the complication and disease recurrence rates for ileocecal resection for pediatric and adult Crohn's disease (CD) and identifies perioperative risk factors for these adverse outcomes in the two groups. Patients who underwent ileocecal resection for CD in a tertiary hospital in Italy (2010-2021) were included. Risk factors for postoperative complications and clinical and surgical disease recurrences were investigated with multivariate models. A total of 96 patients were included (children, 25%). There were no intraoperative complications. Thirty-one (32.3%) patients experienced 35 (36.5%) postoperative complications, and five (5.2%) were severe (Clavien-Dindo III-IV-V), with no intergroup difference for either overall postoperative complication rate (p = 0.257) or severe postoperative complication rate (p = 0.097). Most of these (77.1%) occurred within 30 days after surgery, especially in adults (p = 0.013). The multivariate analysis did not show risk factors for postoperative complications. Clinical and surgical recurrence rates after 5 years were 46.8% and 14.6%, respectively, with no intergroup rate differences. Clinical disease recurrence was positively correlated with previous abdominal surgery (p = 0.047) and negatively correlated with preoperative Hb levels (p = 0.046). A positive correlation was found between perianal disease and both clinical (p = 0.045) and surgical disease recurrences (p = 0.045). Urgent surgery was positively associated with surgical disease recurrence (p = 0.045). Notably, no children underwent urgent surgery in this study. In conclusion, the risk of postoperative complications among CD patients receiving ileocecal resection remains high, but most of them are nonserious. Some factors, such as urgent surgery, may increase the risk of disease recurrences.

Short- and long-term outcomes of robotic versus open radical antegrade modular pancreatosplenectomy: a retrospective propensity score-matched cohort study.

Robotic distal pancreatectomy has increasingly been accepted as it has overcome some of the limitations of open distal pancreatectomy, whilst the outcomes following robotic radical antegrade modular pancreatosplenectomy (RAMPS) in patients with pancreatic ductal adenocarcinoma (PDAC) are still uncertain. This study aimed to evaluate the short and long-term outcomes of robotic RAMPS and open RAMPS for PDAC. The patients who underwent robotic RAMPS and open RAMPS for PDAC at our clinical centre between January 2017 and December 2021 were reviewed. After a propensity score matching (PSM) at a 1:1 ratio, the perioperative and pathological outcomes in the both groups were reviewed. Univariable and multivariable Cox regression analyses were used to identify independent prognosis factors for overall survival (OS) and recurrence-free survival (RFS) of these patients. 318 cases were recorded in robotic and open groups. The robotic group showed advantages in operative time [205.00 (166.00, 240.00) min vs 235 (184.75, 270.00) min, P = 0.002], estimated blood loss [100 (50, 100) ml vs 300 (100, 400) ml, P < 0.001], delayed gastric emptying [0 vs 5.03%, P = 0.007] and postoperative hospital stay [7.00 (5.00, 10.00) days vs 11.00 (8.00, 14.00) days, P < 0.001]. There were no significant differences in rate of severe postoperative complications between the robotic group and the open group. Multivariable analysis showed that carbohydrate antigen 19-9, estimated blood loss, N stage, tumour differentiation, chemotherapy and vascular invasion were independent risk factors for OS and RFS of these patients. Robotic RAMPS was safe and had some advantages over open RAMPS for PDAC. There were no significantly differences in oncological outcomes and long-term survival rates between the robotic and open groups. Robotic RAMPS expanded the indications for minimally invasive surgeries for PDAC to a certain extent.

Value of preoperative biliary drainage in pancreatic head cancer patients with severe obstructive jaundice: A multicenter retrospective study.

Pancreatic head cancer accompanied by obstructive jaundice is a common clinical situation. The aim of this study was to assess the impact of preoperative biliary drainage (PBD) on clinical outcomes in patients with severe obstructive jaundice. Patients with a bilirubin level of ≥250 μmol/L at diagnosis who underwent PBD were included. The primary endpoints and secondary endpoints were the postoperative severe complications rates. Secondary endpoints were the degree of improvement in general condition, predictors of severe postoperative complications, and the impact of PBD on patients with bilirubin levels >300 μmol/L. In total, 289 patients were included, and 188 patients (65.1%) underwent PBD. The patients who met the American Society of Anesthesiologists (ASA) classification II-III stages decreased from 119 to 100 ( P = 0.047) after PBD. The overall severe complications were significantly more frequent in the direct surgery (DS) group than in the PBD group (34.7% vs. 22.9%, P = 0.031), especially the postoperative hemorrhage (6/43 [14.0%] vs. 9/35 [25.7%], P = 0.038) and intra-abdominal infection (6/43 [14.0%] vs. 10/35 [28.6%], P = 0.018). The ASA classifications II-III (odds ratio [OR]=2.89, 95% confidence interval [CI]: 1.38-4.31), P = 0.01) and DS (OR = 3.65, 95% CI: 1.45-7.08; P = 0.003) were independently associated with severe postoperative complications. The occurrence rate of severe postoperative complications in patients with a bilirubin level >300 μmol/L who underwent PBD was significantly lower than in patients who underwent DS (25.6% vs. 40.6%, P = 0.028), but the benefit of PBD was not observed in patients who had a bilirubin level between 250 and 300 μmol/L. PBD is useful in reducing severe postoperative complications, especially in patients with bilirubin levels >300 μmol/L.

Comparing endoscopic mucosal resection with endoscopic submucosal dissection in colorectal adenoma and tumors: Meta-analysis and system review.

This study aimed to evaluate the safety, efficacy, and long-term outcomes of endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) for treating colorectal adenomas and tumors. A systematic literature review was conducted using databases including PubMed, Web of Science, and Embase. Parameters such as number of patients or lesions, histological diagnosis, lesion size, surgery time, en-bloc resection, R0 resection, severe postoperative complications, and local recurrence were extracted and pooled for analysis. A total of 12 retrospective studies involving 1289 patients and 1850 lesions were included in the analysis. EMR was found to have a shorter operation time by 53.6 minutes (95% CI: 51.3, 55.9, P<0.001) and fewer incidences of severe postoperative complications such as perforation and delayed bleeding (OR = 0.40, 95%CI: 0.23, 0.71, P<0.001). On the other hand, ESD had higher rates of en-bloc resection (OR = 0.15, 95%CI: 0.07, 0.30, P<0.001) and R0 resection (OR = 0.32, 95%CI: 0.16, 0.65, P<0.001). Recurrence after EMR was found to be significantly higher than that after ESD surgery (OR = 5.88, 95%CI: 2.15, 16.07, P = 0.037). The study suggests that the choice of surgical method may have a greater impact on recurrence compared to the pathological type, and that ESD may be more suitable for the treatment of malignant lesions despite its higher rates of severe postoperative complications and longer operation time.

Surgical treatment for recurrent cholangiocarcinoma: a single-center series.

The present study aims to assess the results obtained after surgical treatment of cholangiocarcinoma (CC) recurrences. We carried out a single-center retrospective study, including all patients with recurrence of CC. The primary outcome was patient survival after surgical treatment compared with chemotherapy or best supportive care. A multivariate analysis of variables affecting mortality after CC recurrence was performed. Eighteen patients were indicated surgery to treat CC recurrence. Severe postoperative complication rate was 27.8% with a 30-day mortality rate of 16.7%. Median survival after surgery was 15 months (range 0-50) with 1- and 3-year patient survival rates of 55.6% and 16.6%, respectively. Patient survival after surgery or CHT alone, was significantly better than receiving supportive care (p< 0.001). We found no significant difference in survival when comparing CHT alone and surgical treatment (p=0.113). Time to recurrence of <1 year, adjuvant CHT after resection of the primary tumor and undergoing surgery or CHT alone versus best supportive care were independent factors affecting mortality after CC recurrence in the multivariate analysis. Surgery or CHT alone improved patient survival after CC recurrence compared to best supportive care. Surgical treatment did not improve patient survival compared to CHT alone.

Influence of Hemorrhagic Complications of Pancreatoduodenectomy in Patients with Cancer on Short- and Long-Term Mortality.

With a mortality rate of up to 30%, post-pancreatectomy hemorrhage (PPH) remains a serious complication after pancreatoduodenectomy (PD) for cancer. Little is known about the long-term survival of patients after PPH. This retrospective study aimed to evaluate the impact of PPH on long-term survival after PD. The study included 830 patients (PPH, n = 101; non-PPH, n = 729) from two centers, who underwent PD for oncological indications. PPH was defined as any bleeding event occurring within 90 days after surgery. A flexible parametric survival model was used to determine the evolution of the risk of death over time. At postoperative day 90, PPH significantly increased the mortality rate (PPH vs. non-PPH: 19.8% vs. 3.7%, p < 0.0001) and severe postoperative complication rate (85.1% vs. 14.1%, p < 0.0001), and decreased median survival (18.6 months vs. 30.1 months, p = 0.0001). PPH was associated with an increased mortality risk until the sixth postoperative month. After this 6-month period, PPH had no more influence on mortality. PPH had a negative impact on the short-term overall survival beyond postoperative day 90 and up to six months after PD. However, compared to non-PPH patients, this adverse event had no impact on mortality after a 6-month period.

MP34-20 SEVERE POST-OPERATIVE COMPLICATIONS ARE RARE IN PATIENTS WITH URINARY-PUBIC SYMPHYSIS FISTULAE AND PUBIC BONE OSTEOMYELITIS (UPF-OM) UNDERGOING EXTIRPATIVE SURGERY; DATA FROM THE NATIONAL SURGICAL QUALITY IMPROVEMENT PROGRAM

Our pathway requires holding antibiotics for 2 weeks prior to surgery and not administering IV perioperative antibiotics until the bone is removed at the time of extirpative treatment. This study aims to evaluate the rates of post-operative surgical infections and complications after extirpative surgery for UPF-OM. METHODS: Using the NSQIP database, 36 patients undergoing extirpative surgery for UPF-OM were collected between 2016-2021. Pre- and post-operative characteristics and outcomes were evaluated. At our institution patients with UPF-OM undergo a standard workup and treatment pathway including MRI of pelvis confirming osteomyelitis, pre-operative nutritional labs, and optimization of modifiable risk factors. We involve a multi-disciplinary team including urology, orthopedics, infectious disease, plastic surgery, colorectal surgery if concurrent rectourethral fistula, and acute pain service. RESULTS: The median age at time of surgery was 74.32 years (68.46, 78.28). Baseline patient characteristics included history of radiation in all patients, 4 (11.11%) had a history of tobacco use within 1 year, diabetes 10 (27.78%), median albumin 3.4 (3.2, 3.6), and a median BMI of 27.1 (24.2, 30.88). The median operating room time was 371 minutes (344.5, 408) and the median length of hospitalization was 8 days (7, 10). 6 (16.7%) patients had readmissions related to surgery including 1 small bowel obstruction managed conservatively, 2 readmissions for infection, 2 for dehydration, and 1 for anemia/presyncope. No patients had a bowel anastomotic leak, ureteroenteric leak, or rectal injury. During admission no patients had surgical site infections, deep surgical site infections, urinary tract infections, or sepsis/SIRS at 48 hours. CONCLUSIONS: The rates of severe post-operative complications in extirpative surgery for UPF-OM are low. These findings are surprising given the complexity of the disease process and underlying infected/contaminated field inherent to UPF-OM. Given our pathway that withholds antibiotics until late in the extirpative procedure the rates of infection are exceedingly low and were only present at delayed readmissions.

CT-determined sarcopenia is associated with neutropenia in patients undergoing hyperthermic intraperitoneal chemotherapy for gastrointestinal cancer

BackgroundWith better patient selection and the increasing experience in patients undergoing hyperthermic intraperitoneal chemotherapy (HIPEC) combined surgery, the rate of severe postoperative complications and mortality decreased significantly. However, leukopenia and neutropenia were still a particular concern, and their relation to sarcopenia was not clarified.MethodsData of consecutive patients who underwent HIPEC for gastrointestinal cancer were collected and analyzed retrospectively between September 2020 and August 2022. Sarcopenia was assessed using psoas muscle index (PMI) at the L3 level on preoperative computed tomography (CT).ResultsAmong 103 patients enrolled, 37 (35.9%) were classified as sarcopenic. Most leukopenia and neutropenia occurred during the hospital leaving period after HIPEC and surgery. Before the first time of postoperative chemotherapy, the blood tests revealed 11 (29.73%) and 6 (9.09%) patients were diagnosed with neutropenia in sarcopenia and no sarcopenia groups, respectively. Logistic regression analysis revealed sarcopenia was independently associated with the increased risk of neutropenia (OR 5.58, 95% CI 1.70–18.29, p = 0.005). An incremental albumin level was protective against the occurrence of leukopenia and neutropenia.ConclusionsSarcopenia and low albumin level were significantly associated with an increased rate of delayed neutropenia after HIPEC in that disease setting and could be the preoperative risk predictors.

Comparison of Neoadjuvant Systemic Chemotherapy Protocols for the Curative-Intent Management of Peritoneal Metastases from Colorectal Cancer, Regarding Morphological Response, Pathological Response, and Long-Term Outcomes: A Retrospective Study.

Selected patients with colorectal cancer peritoneal metastases (CRPM) could be offered a curative-intent strategy based on complete cytoreductive surgery (CRS), potentially combined with hyperthermic intraperitoneal chemotherapy (HIPEC) and perioperative systemic chemotherapy. The impact of different neoadjuvant systemic chemotherapy (NACT) regimens remains unclear due to a lack of comparative data. Consecutive CRPM patients from a monocentric database who were treated with complete CRS after single-line NACT were included in this study. Chemotherapy regimens were tailored as a doublet drug (FOLFOX/FOLFIRI) with/without targeted therapy (anti-epidermal growth factor receptor/bevacizumab) and triplet-drug combination (FOLFIRINOX). Morphological response (MR) was assessed using the Response Evaluation Criteria in Solid Tumors criteria, and pathological response (PR) was assessed using the Peritoneal Regression Grading Score (PRGS). Long-term oncologic outcomes were compared. The cohort comprised 388 patients, including 127, 202, and 59 patients in the doublet, doublet+targeted, and triplet groups, respectively. MR rates were higher in the triplet (68.0%) and doublet+targeted groups (64.2%) when compared with the doublet group (42.4%, p=0.003). Complete and major PRs were observed in 13.6% and 32.0% of patients, respectively. Higher MR rates were observed after doublet+targeted or triplet regimens, while no difference was observed for PR rates. In multivariate analysis, FOLFIRINOX was independently associated with better overall survival (hazard ratio 0.49, 95% confidence interval 0.25-0.96; p=0.037). FOLFIRINOX also resulted in a higher rate of severe postoperative complications. In this retrospective study, a FOLFIRINOX regimen as NACT seemed to result in better long-term outcomes for CRPM patients after complete CRS/HIPEC, although with higher morbidity. Prospective studies are needed, including groups without NACT and those with FOLFIRINOX+bevacizumab.

Preoperative Hypoalbuminemia as a Predictor of Severe Postoperative Complications in Patients Undergoing Whipple Pancreatoduodenectomy.

Pancreaticoduodenectomy (PD) known as Whipple procedure is still one of the most complex abdominal surgeries used for treatment of periampullary tumors. PD is often followed with postoperative complications (pancreatic, biliar or intestinal fistula, haemorrhage, intraabdominal abscess, delayed gastric empting. Severe postoperative complications (SPC) can be reason for reoperation and reason of bad outcome of treatment and life treathening condition. To investigate predicitive value of preoperative hypoalbuminemia for severe postoperative complications (SPC) in patients who have undergone Whipple pancreaticoduodenetomy (PD). However, no similiar study has been ever reported from our country until now. In this retrospective-prospective study, 100 patients who have had Whipple pancreaticoduodenectomy for malignant periampullary tumors at the Department for Surgery of University Clinic Center Tuzla, Bosnia and Herzegovina were enrolled, from january of 2009 to decembre of 2021. All patients were preoperatively analysed according to serum albumine levels and presensce of hypolabuminemia (serum albumine levels <32g/l). Serum albumine biochemical test were done 1-2 days preoperatively. Clavien Dindo classification was used for determination patients with SPC. Patients who did not have SPC belonged to (I-II) Clavien Dindo group of patients while those who had SPC belonged to( III-V) Clavien Dindo group of patients. Out of 100 patients who have undergone pancreaticoduodenetomy, in 55 (55%) patients postoperative complications were noticed. Mortality rate was 18 (18%) and reoperation has been done in 20 cases (20%). SPC were noticed in 19 patients and most often were: delayed gastric emptying (20%), pancreatic fistula (13%) and intraabdominal collections (9%). Hypoalbuminemic patients had a significantly higher rate of severe postoperative complications ( p<0.05). Using hypoalbuminemia-SPC correlation analaysis, there is confirmed statistically significant correlation between hypoalbuminemia and SPC (ρ= 0.236; p<0.05). Preoperative hypoalbuminemia can be used as predictor and prognostic factor for severe postoperative complications after Whipple pancreaticoduodenectomy. Identification and optimization of serum albumin level prior to Whipple pancreatoduodenectomy may improve surgical outcomes.

Comparison of Different Laparoscopic Sacropexy Procedures for Advanced Uterine Prolapse: A Retrospective Analysis

To compare the long-term outcomes and complications of 3 different variants of laparoscopic sacropexy. Single-center retrospective cohort study. A tertiary university hospital. A total of 483 patients with advanced uterine prolapse who underwent laparoscopic sacrohysteropexy (LSH), laparoscopic supracervical hysterectomy with concomitant laparoscopic sacrocervicopexy (LSCH+LSC), or total laparoscopic hysterectomy with concomitant laparoscopic sacrocolpopexy (TLH+LSC). Demographic data, Pelvic Organ Prolapse Quantification scores, questionnaire results, surgical conditions, postoperative outcomes, and complications were all extracted from medical and follow-up records. Between April 2012 and December 2020, 277 women underwent LSH, 95 women underwent LSCH+LSC, and 111 women underwent TLH+LSC. LSH procedures were associated with statistically significantly least blood loss and least postoperative hospital days and catheterization days (all p <.001). During the median follow-up of 32 months (13-117 months), analysis of the data revealed notable anatomic correction in all groups regarding Pelvic Organ Prolapse Quantification measurements (p <.001), and the anatomic cure rate showed no significant difference among these 3 groups (p=.273). No statistically significant differences were detected for prolapse recurrence (p=.171) and functional improvements among these groups. Neither intraoperative injuries (p=.098) nor total postoperative complications (p=.218) differed considerably, whereas the rate of severe postoperative complications (p <.001) including mesh exposure (p=.004) was significantly higher in the TLH+LSC group than that in the other groups. LSH is the appropriate choice for women with uterine prolapse without contraindications for uterine preservation. For patients with benign uterine lesions and a normal cervix, LSCH+LSC is a safer approach that provides similar anatomic results and improved quality of life scores that are similar to those of TLH+LSC. For patients with lesions in the uterus and cervix, TLH+LSC should be selected.

Calf circumference is an independent predictor of postoperative complications in the surgical treatment of head and neck cance

Introduction: The prevalence of malnutrition is high among head and neck cancer (HNC) patients and negatively impacts their quality of life, treatment, and survival rates. Objective: To identify preoperative nutritional variables capable of predicting postoperative complications in surgically treated HNC patients. Methods: This was a prospective cohort study of HNC patients referred for surgery as initial treatment. Results: Sixty patients were included in the study; they had a median age of 65.5 years, were mostly men (85%), and most had low education levels (90%) and low household income (78.3%). The incidence rate of severe postoperative complications (grades II, III, IV, and V according to the Clavien-Dindo grading system) was found to be 50%. The nutritional variables under investigation, namely calf circumference (CC), triceps skinfold, body mass index, and adductor pollicis muscle thickness were shown to predict postoperative complications in HNC patients, especially CC, which was found to be an independent predictor of complications (OR=0.8; 95%CI: 0.65–0.96). Each 1-cm increase in calf circumference was associated with a 20% decrease in the risk of postoperative complications. Conclusion: Our findings show the nutritional variables studied are useful in the prognostic assessment of HNC surgery.

Is there a weekend effect in emergency surgery for colorectal carcinoma? Analysis from the German StuDoQ registry

Higher postoperative mortality has been observed among patients who received emergency colorectal surgery on the weekend compared to during the week. The aim of this study was to determine whether the weekday of emergency surgery affects the 30-day mortality and postoperative course in emergency colorectal surgery. Prospectively acquired data from the 2010-2017 German StuDoQ|Colorectal surgery registries were analysed. Differences in 30-day mortality, transfer and length of stay (MTL30) (primary endpoints), postoperative complications, length of stay and pathological results of resected specimens (secondary endpoints) were assessed. Multivariable analysis was performed to identify independent risk factors for postoperative outcome. In total, 1,174 patients were included in the analysis. Major postoperative complications and the need for reoperation were observed more frequently for emergency colorectal surgery performed during the week compared to the weekend (23.01 vs. 15.28%, p = 0.036 and 17.96% vs. 11.11%, p = 0.040, respectively). In contrast, patients who received emergency surgery on the weekend presented with significantly higher UICC tumour stages (UICC III 44.06 vs. 34.15%, p = 0.020) compared to patients with emergency colorectal surgery on a weekday. Emergency surgery performed during the week was an independent risk factor for the development of severe postoperative complications (OR 1.69 [1.04-2.74], p = 0.033) and need for reoperation (OR 1.79 [1.02-3.05], p = 0.041) in the multivariable analysis. Emergency surgery for colorectal carcinoma in Germany is performed with equal postoperative MTL30 and mortality throughout the entire week. However, emergency surgery during the week seems to be associated with a higher rate of severe postoperative complications and reoperation.

Feasibility of repeated ipsilateral anatomical pulmonary resection.

This study aimed to elucidate the feasibility of repeated ipsilateral anatomical pulmonary resection. The subjects of this retrospective analysis were 50 patients who underwent ipsilateral anatomical pulmonary resection after major lung surgery. The patients were divided into two groups according to the type of primary operation performed: a repeated anatomical pulmonary resection group (RA group; n = 24) and an anatomical pulmonary resection after wedge resection group (AW group; n = 26). We compared the perioperative outcomes of the two groups. Completion lobectomy was performed in 9 of the 24 patients (38%) from the RA group and adhesion of the pulmonary hilum was more severe in this group (P = 0.004). Although the operative time was significantly longer in the RA group (P = 0.030), there was no significant difference in the amount of blood loss (P = 0.217) between the groups. A significantly higher rate of severe postoperative complications was observed in the RA group (42%) than in the AW group (12%) (P = 0.024). None of the patients who underwent repeated surgery died within 90days postoperatively. Although repeated anatomical pulmonary resection is a more challenging procedure than anatomical resection after wedge resection, it does not increase short-term mortality; therefore, it is a feasible treatment option.

A physiology-based trigger score to guide perioperative transfusion of allogeneic red blood cells: A multicentre randomised controlled trial.

Restrictive blood transfusion is recommended by major guidelines for perioperative management, but requires objective assessment at 7-10g/dl haemoglobin (Hb). A scoring system that considers the physiological needs of the heart may simply the practice and reduce transfusion. Patients (14-65 years of age) undergoing non-cardiac surgery were randomised at a 1:1 ratio to a control group versus a Perioperative Transfusion Trigger Score (POTTS) group. POTTS (maximum of 10) was calculated as 6 plus the following: adrenaline infusion rate (0 for no infusion, 1 for ≤0.05 μg·kg-1 ·min-1 , and 2 for higher rate), FiO2 to keep SpO2 at ≥95% (0 for ≤35%, 1 for 36%-50%, and 2 for higher), core temperature (0 for <38°C, 1 for 38-40°C, and 2 for higher), and angina history (0 for no, 1 for exertional, and 2 for resting). Transfusion is indicated when actual Hb is lower than the calculated POTTS in individual patients. Transfusion in the control group was based on the 2012 American Association for Blood Banks (AABB) guideline. The primary outcome was the proportion of the patients requiring transfusion of allogeneic red blood cells (RBCs) during the perioperative period (until discharge from hospital), as assessed in the intention-to-treat (ITT) population (all randomised subjects). A total of 864 patients (mean age 44.4 years, 244 men and 620 women) were enrolled from December 2017 to January 2021 (433 in the control and 431 in the POTTS group). Baseline Hb was 9.2 ± 1.8 and 9.2 ± 1.7g/dl in the control and POTTS groups, respectively. In the ITT analysis, the proportion of the patients receiving allogeneic RBCs was 43.9% (190/433) in the control group versus 36.9% (159/431) in the POTTS group (p=0.036). Lower rate of allogeneic RBCs transfusion in the POTTS group was also evident in the per-protocol analysis (42.8% vs. 35.5%, p=0.030). Transfusion volume was 4.0 (2.0, 6.0) and 3.5 (2.0, 5.5) units (200 ml/unit) in the control and POTTS groups, respectively (p=0.25). The rate of severe postoperative complications (Clavien-Dindo grade IIIa and higher) was 3.9% in the control group versus 1.2% in the POTTS group (p=0.010). Transfusion of allogeneic RBCs based on the POTTS was safe and reduced the transfusion requirement in patients undergoing non-cardiac surgery.

Preoperative Anemia Is a Predictor of Worse Postoperative Outcomes Following Open Pancreatoduodenectomy: A Propensity Score-Based Analysis.

BackgroundPreoperative anemia is a common clinical situation proved to be associated with severe outcomes in major surgeries, but not in pancreatic surgery. We aim to study the impact of preoperative anemia on morbidity and mortality in patients undergoing open pancreatoduodenectomy and use propensity score matching (PSM) to balance the basal data and reduce bias.MethodsWe analyzed the data of consecutive patients undergoing open pancreatoduodenectomy with a complete record of preoperative hemoglobin, at two pancreatic centers in China between 2015 and 2019. Anemia is defined as hemoglobin less than 12 g/dl for male and 11 g/dl for female, following Chinese criteria. We compared clinical and economic outcomes before and after PSM and used logistic regression analysis to assess the correlation between variables and anemia.ResultsThe unmatched initial cohort consisted of 517 patients. A total of 148 cases (28.6%) were diagnosed with anemia at admission, and no case received a preoperative blood transfusion or anti-anemia therapy. After PSM, there were 126 cases in each group. The rate of severe postoperative complications was significantly higher in the anemia group than in the normal group (43.7% vs. 27.0%, p = 0.006), among which the differences in prevalence of clinically relevant postoperative pancreatic fistula (CR-POPF) (31.0% vs. 15.9%, p = 0.005) and cardiac and cerebrovascular events (4.0% vs. 0.0%, p = 0.024) were the most significant. The costs involved were more in the anemia group (26958.2 ± 21671.9 vs. 20987.7 ± 10237.9 USD, p = 0.013). Among anemic patients, receiver operating characteristic (ROC) curve analysis shows the cut-off value of hemoglobin, below which, patients are prone to suffer from major complications (104.5 g/l in male and 90.5 g/l in female). Among all patients, multivariate analysis showed that preoperative obstructive jaundice [odds ratio (OR) = 1.813, 95% confidence interval (CI) (1.206–2.725), p = 0.004] and pancreatic ductal adenocarcinoma [OR = 1.861, 95% CI (1.178–2.939), p = 0.008] were predictors of anemia. Among paired patients, preoperative anemia [OR = 2.593, 95% CI (1.481–5.541), p = 0.001] and malignant pathology [OR = 4.266, 95% CI (1.597–11.395), p = 0.004] were predictors of postoperative severe complications.ConclusionPreoperative anemia is a predictor of worse postoperative outcomes following open pancreatoduodenectomy and needs to be identified and treated.

Day of surgery and mortality after pancreatoduodenectomy: A retrospective analysis of 29270 surgical cases of pancreatic head cancer from Japan.

The day of the week can impact medical treatment outcomes; however, few large-scale, disease-specific studies have focused on the association between the day of the week and mortality in patients after pancreatoduodenectomy for pancreatic head cancer. Data were obtained from the National Clinical Database. Twenty-two clinical variables were adopted for hierarchal logistic regression modeling to determine adjusted odds ratios (ORs) for surgical mortality after elective pancreatoduodenectomy. The 30-day mortality and surgical mortality rates were 1.0% and 1.7%, respectively (n=29720). Surgeries were performed the least on Fridays (13.4%) compared with other weekdays. Crude rates of severe postoperative complications (mean, 14.1%; range, 13.5%-14.8%) and pancreatic fistulas (mean, 10.0%; range, 9.6%-10.3%) remained stable throughout the week. Unadjusted/adjusted ORs did not significantly differ between Friday and Monday (0.868, 95% CI: 0.636-1.173, P=.365, and 0.928, 95% CI: 0.668-1.287, P=.653, respectively), and results were similar for the remaining weekdays. Nineteen independent factors were associated with surgical mortality. The rate of perioperative mortality for elective pancreatoduodenectomy is low in Japan, with no evidence of disparities in surgical mortality rates between weekdays.

Feasibility and safety of robotic-assisted total pancreatectomy: a pilot western series

This study was designed to demonstrate non-inferiority of robot-assisted total pancreatectomy (RATP) to open total pancreatectomy (OPT) based on an intention-to-treat analysis, having occurrence of severe post-operative complications (SPC) as primary study endpoint. The two groups were matched (2:1) by propensity scores. Assuming a rate of SPC of 22.5% (non-inferiority margin: 15%; α: 0.05; β: 0.20; power: 80%), a total of 25 patients were required per group. During the study period (October 2008–December 2019), 209 patients received a total pancreatectomy. After application of exclusion and inclusion criteria, matched groups were extracted from an overall cohort of 132 patients (OPT: 107; RATP: 25). Before matching, the two groups were different with respect to prevalence of cardiac disease (24.3% versus 4.0%; p = 0.03), presence of jaundice (45.8% versus 12.0%; p = 0.002), presence of a biliary drainage (23.4% versus 0; p = 0.004), history of weight loss (28.0% versus 8.0%; p = 0.04), and vein involvement (55.1% versus 28.0%) (p = 0.03). After matching, the two groups (OTP: 50; RATP: 25) were well balanced. Regarding primary study endpoint, SPC developed in 13 patients (26.0%) after OTP and in 6 patients (24.0%) after RATP (p = 0.85). Regarding secondary study endpoints, RATP was associated with longer median operating times [475 (408.8–582.5) versus 585 min (525–637.5) p = 0.003]. After a median follow-up time of 23.7 months (10.4–71), overall survival time [22.6 (11.2–81.2) versus NA (27.3–NA) p = 0.006] and cancer-specific survival [22.6 (11.2–NA) versus NA (27.3–NA) p = 0.02] were improved in patients undergoing RATP. In carefully selected patients, robot-assisted total pancreatectomy is non-inferior to open total pancreatectomy regarding occurrence of severe post-operative complications.
