Abstract Background: Morbidity and mortality after pancreaticoduodenectomy (PD) have been associated with postoperative pancreatic fistula (POPF). Pancreatic anastomosis is challenging for most surgeons, and there is no universal or standardized technique. This study compared the incidence of POPF between the pair-watch suturing technique (PWST) and duct-to-mucosa pancreaticojejunostomy (PJ) anastomosis technique. Methods: This retrospective cohort analysis included 71 patients who underwent a PD between January 2009 and October 2018. The incidence and risk factors of complications after PWST and duct-to-mucosa PJ anastomoses were compared. Results: There was no significant difference in the incidence of POPF between the PWST (n = 7; 30.4%) and duct-to-mucosa PJ (n = 9; 18.7%) groups. The tumor site (p = 0.001) and pancreas density on computed tomography without contrast (p = 0.002) were significantly different between the groups. Age ≥ 60 years (odds ratio (OR): 11.07; 95% confidence interval (CI): 1.14–107.36; p = 0.038) and pancreatic body mass/duct size (B/W) ratio (OR: 1.41; 95% CI: 1.04–1.91; p = 0.029) were identified as significant risk factors for POPF. International Study Group for Pancreatic Fistula grade B POPF, wound infections, and pneumonia occurred more frequently in patients who underwent a duct-to-mucosa PJ anastomosis. However, the postoperative complications were not significantly different between the groups. Conclusions: The incidence of clinically relevant POPF was similar between patients who underwent the PWST and those who underwent a duct-to-mucosa PJ anastomosis. However, a preoperative risk factor assessment for the evaluation of tumor site, patient age, and B/W ratio could help determine which surgical technique should be used in individual patients.

Objective To examine risk factors for and causes of severe postoperative pancreatic fistula (sPOPF) after laparoscopic gastrectomy (LG) Summary of Background Data There are few reports on POPF after LG. Methods Between February 2012 and March 2014, we examined 86 patients who underwent LG comparing them with 33 patients who underwent open gastrectomy (OG) for gastric cancer. Risk factors for severe POPF (sPOPF) of Clavien-Dindo grade IIIa or higher were examined. To investigate causes of sPOPF, we reviewed unedited video recordings of laparoscopic surgical procedures. Results sPOPF occurred to 3 patients (3.5%) after LG and 1 patient (3.0%) after OG, indicating no significant difference (p=0.901). Univariate analysis showed no significant risk factors for sPOPF after LG. By reviewing video recordings, all 3 patients with sPOPF after LG had direct pancreatic injury by ultrasonically activated device (USAD) during peripancreatic lymphadenectomy. In 2 of them, pancreas was injured while the contour of pancreas was obscured by bleeding. Durations of drain placement and postoperative hospitalization were longer for patients with sPOPF than for those without POPF or grades I and II POPF (p = 0.003, 0.018; respectively). Conclusions No risk factors for sPOPF after LG could be identified. USAD-induced direct pancreatic injury resulted in sPOPF, which significantly complicated the postoperative clinical course. Direct pancreatic injury can occur whether patient has previously reported risk factors (i.e. male, high BMI, distal pancreatectomy) or not. To prevent pancreatic injury, surgeons should manage hemostasis and keep good surgical field to recognize the contour of pancreas accurately.

Introduction: Postoperative pancreatic fistula (POPF) is a potentially life-threatening complication after pancreaticoduodenectomy (PD). It is observed when the amylase activity in the drain fluid exceeds three times the normal upper value. Grades B and C of POPF are considered as clinically relevant. Fistula might originate due to failure of healing of a pancreatic anastomosis or from raw pancreatic surface. Materials and methods: 18 retrospective and prospective studies published between 2015 and 2020 were included in this meta-analysis. Total number of patients was 5836. To investigate potential risk factors associated with the occurrence of POPF, odds ratios (OR) with 95% confidence intervals (CI) were calculated. To compare discontinuous data, mean differences (MD) were calculated. Results: 13 factors were divided into preoperative and intraoperative groups. Male sex, higher BMI, soft pancreatic texture and small pancreatic duct were considered as significant risk factors while vascular resection lowered the risk of development pancreatic fistula. Discussion: It is considered that the development of POPF is associated with intrapancreatic fat. More severe infiltration with fat tissue is responsible for soft texture of the gland, while higher BMI is one of the risk factors of increased pancreatic fat. On the contrary, diabetes is associated with fibrotic pancreas which could lower the risk of developing POPF.

Background/Purpose: This study aimed to evaluate the feasibility and safety of a novel pancreaticogastrostomy technique for diminishing pancreatic fistulas after pancreaticoduodenectomy using gastric wrapping of the pancreatic stump with a twin square-shaped horizontal mattress and a suture fixing the main pancreatic duct to the gastric mucosa anastomosis [twin square wrapping (TSW) method]. Methods: Fifty-three patients undergoing pancreaticogastrostomy after pancreaticoduodenectomy were included in the study and chronologically divided into a conventional group (n = 32) and a TSW group (n = 21). The perioperative factors and the postoperative outcomes were retrospectively analyzed. Results: The operating time for the pancreatic anastomosis, the total operating time, and the blood loss volume in the TSW group were lower than in the conventional group, but without a statistically significant difference. The TSW group had a significantly lower postoperative white blood cell count and C-reactive protein level, with a reduced intra-abdominal fluid accumulation as assessed by computed tomography on postoperative day 7, had a lower incidence of postoperative complications and pancreatic fistulas, and achieved a shorter duration of drain placement and shorter postoperative hospital stays as compared to the conventional group. Conclusions: The TSW technique should be considered for reducing pancreatic fistulas by diminishing the postoperative inflammatory response and improving patient outcomes without increasing the operating time.

Abstract Introduction. As Ph-positive (Ph+) ALL in adults remains less favorable in prognosis than other ALL, and by expert opinion needs non-intensive chemotherapy protocols and new generation TKI with the majority of pts undergoing allo-HSCT, the results of treatment based on the different approach: de-escalated but continuous treatment with the change of TKI according to the molecular response and allo-HSCT may be of interest and provide new insights to the treatment of Ph+ ALL. Aim. To evaluate survival and outcomes in different risk groups in pts with Ph+ ALL in the RALL-study (Ph+ALL-2009, Ph+ALL-2012 and Ph+ALL-2012m protocols). Patients and methods. Between January 2010 and June 2021, 74 new Ph+ ALL cases were diagnosed in 6 centers of the RALL-group and 63 of them were evaluable for analysis (median age 37 years (17-73), m/f 32(43%)/42(57%), CNS disease in 13(21%) pts, WBC>30*10 9/l in 27(43%) pts, bcr/abl transcript p190/p210/p190+210 in 31(60%)/12(23%)/9(17%) cases). Standard cytogenetic was performed in all 63 pts, 1 had no mitosis, 6(10%) monosomy 7 and 2 (3%) complex karyotypes were detected. All pts were treated according to RALL protocols with continuous Imatinib. Ph+ALL-2009 protocol included 600 mg Imatinib with prednisone, VNCR, L-asp, Dauno, Cph, followed by 6-MP and MTX. Imatinib had to be changed to Dasatinib (140 mg) after non-achievement of molecular complete response (MolCR) on day 70. MolCR was defined as bcr/abl chimeric transcript <0,01% by PCR with 10 -4 sensitivity. In protocols Ph+ALL-2012 and Ph+ALLm, we de-intensified chemotherapy: reduced Dauno, Cph and L-asp doses, accordingly. All pts were considered as candidates for allogeneic HSCT in CR1 if HLA-identical donor was available. 36 (57%) pts underwent HSCT in the first-line therapy: 2(6%) autologous, 9 (25%) matched related, 20 (56%) matched unrelated and 5 (13%) haplo-HSCT. Results. Hematological complete remission (CR) was achieved in 60 (95%) of 63 pts (1 early death and 2 refractory cases occurred). On day 70, MolCR was achieved in 21(38%) of 56 pts. Death on therapy in CR (within 5 months of induction/consolidation) was registered in 4 (6%) cases. The major causes of the non-relapsed mortality in unrelated allo-HSCT (n=9) were aGVHD and severe infections, at a median +4 months after HSCT. The 5-year overall survival (OS) and disease-free survival (DFS) for all 63 pts were 58% and 45%, respectively. The long-term outcome on different protocols (Ph+ALL-2009, Ph+ALL-2012 and Ph+ALL-2012m) were similar: 3-year OS - 55% vs 51% vs 75% (p=0,27), 3-year DFS - 56% vs 44% vs 50% (p=0,54), respectively. The 5-year OS was 65% vs 61% (p=0,84), and DFS was 57% vs 31% (p=0,24) in transplanted vs non-transplanted patients by landmark analysis with a median 5,3 month of CR. Landmark analysis of 5-year OS for transplanted and non-transplanted pts depending on age showed no significant difference for both groups: >45y 40% vs 80%; and ≤45y 70% vs 49%, respectively (p=0,1625), although data for 5-year OS was still not mature at the time of analysis. DFS was significantly different in transplanted vs. non-transplanted pts: >45y 40% vs 71%; ≤45y 61% vs 0%; respectively (p=0,0439). In a multivariate analysis for Ph+ ALL among common risk factors (age > 45y, WBC>30, LDH>2N, immunophenotype, late MolCR >70d, CNS leukemia) WBC>30, HSCT were significant risk factors for OS and DFS. Conclusions. Our data demonstrate that de-intensification of chemotherapy does not affect the efficacy of Ph+ ALL therapy in the era of TKIs. We confirmed that patients older than 45y old could be treated by chemotherapy with TKI (new generation TKI if needed) only, but all pts younger than 45y should be considered for HSCT.

Background: Central venous catheters (CVCs) have been essential devices for the treatment of children with hematological and oncological disorders. Only few studies investigated the complications and selections of different types of CVCs in these pediatric patients. This study aimed to compare risk factors for unplanned removal of two commonly used CVCs, i.e., peripherally inserted central catheters (PICCs) and tunneled CVCs, and propose better device selection for the patient. Procedure: This retrospective, single center cohort analysis was conducted on pediatric patients with hematological and oncological disorders inserted with either a PICC or a tunneled CVC. Results: Between January 1, 2013, and December 31, 2015, 89 patients inserted with tunneled CVCs (total 21,395 catheter-days) and 84 with PICCs (total 9,177 catheter-days) were followed up until the catheter removal. The median duration of catheterization was 88 days in PICCs and 186 days in tunneled CVCs (p = 1.24×10-9). PICCs at the 3-month cumulative incidence of catheter occlusion (5.2% vs. 0%, p = 4.08×10-3) and total unplanned removal (29.0% vs 7.0%, p = 0.0316) were significantly higher, whereas no significant difference was observed in the cumulative incidence of central line-associated bloodstream infection (11.8% vs. 2.3%, p = 0.664). Multivariable analysis identified younger age (<2 years) (subdistribution hazard ratio [SHR], 2.29; 95% confidence interval [CI], 1.27–4.14) and PICCs (SHR, 2.73; 95% CI, 1.48–5.02) were independent risk factors for unplanned removal. Conclusion: Our results suggest that tunnel CVCs would be a preferred device for children with hematological and oncological disorders requiring long-term, intensive treatment.

Background. Postpartum depression (PPD) is considered as one of the mood disturbances occurring during 2-3 months after delivery. The present study aimed to determine the prevalence of PPD and its associated risk factors in border city of Ilam, western Iran.Methods. Through a descriptive cross-sectional study in 2011, overall, 197 women who attended Obstetrics & Gynecology clinics postpartumly in the border city of Ilam, western Iran, were randomly recruited. A standard questionnaire that was completed by a trained midwife through face to face interviews was used for data gathering.Results. Mean age ± standard deviations was 27.9 ± 5.2 years. Prevalence of PPD was estimated to be 34.8% (95% CI: 27.7–41.7). A significant difference was observed among depression scores before and after delivery (P≤0.001). Type of delivery (P=0.044), low socioeconomic status (P=0.011), and women having low educational level (P=0.009) were the most important significant risk factors associated with PPD. The regression analysis showed that employed mothers compared to housekeepers were more at risk for PPD (adjusted OR = 2.01, 95% CI: 1.22–2.28,P=0.003).Conclusions. Prevalence of PPD in western Iran was slightly higher than the corresponding rate from either national or international reports.

Abstract Background Intraoperative periprosthetic fractures (IPF) are a well-described complication following hip hemiarthroplasty. Our aims were to identify risk factors that characterize IPF and to investigate postoperative mobility. Methods We retrospectively reviewed 481 bipolar hemiarthroplasties for displaced femoral neck fractures; of which, 421 (87.5%) were performed without cement, from January 2013 to March 2018. Data on the patients’ demographics, comorbidities, femoral canal geometry (Dorr canal type, Canal Flare Index), surgeon’s experience (junior vs. senior surgeon), and timing of surgery (daytime vs. on-call duty) were obtained. In patients with intraoperative fractures, further information was obtained. Patient mobility was assessed using matched-pair analysis. Mobility was classified according to the NHFD mobility score. The chi-square test, Fisher’s exact test, and Fisher-Freeman-Halton exact test were used for comparison between categorical variables, while the Mann-Whitney U test was used for continuous variables. The data analysis was performed using SPSS. Results Of 481 procedures, 34 (7.1%) IPFs were encountered. The Dorr canal type C was identified as a significant risk factor (p = .004). Other risk factors included female sex (OR 2.30, 95% CI .872–6.079), stovepipe femur (OR 1.749, 95% CI .823–3.713), junior surgeon (OR 1.204, 95% CI .596–2.432), and on-call-duty surgery (OR 1.471, 95% CI .711–3.046), although none showed a significant difference. Of 34 IPFs, 25 (73.5%) were classified as Vancouver type A. The treatment of choice was cerclage wiring. Within the 12 matched pairs identified, the postoperative mobility was slightly worse for the IPF group (delta = .41). Conclusions IPF is a serious complication with bipolar hemiarthroplasty. The identification of risk factors preoperatively, in particular femur shape, is crucial and should be incorporated into the decision-making process.

Abstract Background Aseptic loosening has become the main cause of prosthetic failure in medium- to long-term follow-up. The objective of this study was to establish and validate a nomogram model for aseptic loosening after tumor prosthetic replacement around knee. Methods We collected data on patients who underwent tumor prosthetic replacements. The following risk factors were analyzed: tumor site, stem length, resection length, prosthetic motion mode, sex, age, extra-cortical grafting, custom or modular, stem diameter, stem material, tumor type, activity intensity, and BMI. We used univariate and multivariate Cox regression for analysis. Finally, the significant risk factors were used to establish the nomogram model. Results The stem length, resection length, tumor site, and prosthetic motion mode showed a tendency to be related to aseptic loosening, according to the univariate analysis. Multivariate analysis showed that the tumor site, stem length, and prosthetic motion mode were independent risk factors. The internal validation indicated that the nomogram model had acceptable predictive accuracy. Conclusions A nomogram model was developed for predicting the prosthetic survival rate without aseptic loosening. Patients with distal femoral tumors and those who are applied with fixed hinge and short-stem prostheses are more likely to be exposed to aseptic loosening.

Abstract Abnormal TCD defined as high mean maximum velocities &gt; 200 cm/sec are highly predictive of stroke risk and justify long term transfusion program. Outcome and risk factors of conditional TCD defined as velocities 170–200 cm/sec remains to be described. Patients and methods Since 1992, 371 pediatric SCD patients (303 SS, 44 SC, 18 Sß+, 6 Sß0) were systematically explored once a year by TCD. The newborn screened cohort (n=174) had the first TCD exploration between 12 and 18 months of age. TCD was performed with a real-time imaging unit, using a 2 MHz sector transducer with color Doppler capabilities. Biological data were assessed at baseline, after the age of 1.5 years and remotely of transfusion or VOC. We report the characteristics and the outcome in patients (n=43) with an history of conditional TCD defined by mean maximum velocities ranging between 170 and 200 cm/s in the ACM, the ACA or the ICA. Results: The mean follow-up of TCD monitoring was 5,5 years (0 – 11,8 y). All patients with an history of conditional doppler were SS/Sb0 (n=43). Mean (SD) age of patients at the time of their first conditional TCD was 4.3 years (2.2) whereas in our series the mean age at abnormal TCD (&gt; 200 cm/sec) occurrence was 6.6 years (3.2). Comparison of basal parameters showed highly significant differences between patients with conditional TCD and those with normal TCD: Hb 7g4 vs 8g5 (p&lt;0.001), MCV 82.8 vs 79 (p=0.047). We also had found such differences between patients with normal and those with abnormal TCD (Hb and MCV p&lt; 0.001). Two patients were lost of follow-up. Two patients died during a trip to Africa. Conditional TCD became abnormal in 11/43 patients and justified transfusion program. Mean (SD) conversion delay was 1.8 (2.0) years (range 0.5–7y). No stroke occurred. 16 patients required a treatment intensification for other indications (frequent VOC/ACS, splenic sequestrations): 6 were transplanted and 10 received HU or TP. Significant risk factors (Pearson) of conversion to abnormal were the age at time of conditional TCD occurrence &lt; 3 y (p&lt;0.001), baseline Hb &lt; 7g/dl (p=0.02) and MCV &gt; 80 (p=0.04). MRI/MRA was performed in 31/43 patients and showed ischemic lesions in 5 of them at the mean (SD) age of 7.1 y (1.8) (range 4.5–8.9): no significant difference was observed in the occurrence of lesions between the 2 groups. Conclusions This study confirms the importance of age as predictive factor of conditional to abnormal TCD conversion with a risk of 64% when first conditional TCD occured before the age of 3 years. TCD has to be frequently controled during the 5 first years of life.
