Microbiological profiles and clinical outcomes of critically ill surgical patients with lower gastrointestinal perforation in Japan: a single-center retrospective observational study

BackgroundLower gastrointestinal perforation (LGP) is a surgical emergency disease that can result in secondary bacterial peritonitis. Microbiological studies on LGP are rare. The present study aimed to ascertain the microbiological profile of LGP in patients admitted to the intensive care unit (ICU) at our institute after surgery. In addition, we investigated whether initial empirical therapy with vancomycin was associated with in-hospital mortality, duration of ICU stay, and duration of ventilator support.MethodsThis single-center, retrospective, observational study was conducted at Kobe City Medical Center General Hospital, Japan. The study population included all patients diagnosed with LGP who were admitted to the ICU after emergency surgery between 2017 and 2023. The primary outcome assessed was the microbiological profile of microorganisms isolated from ascites fluid and blood of the participants. The secondary end-points were in-hospital mortality, duration of ICU stay, and duration of ventilator support. We performed univariate and multivariate regression analyses to evaluate the end-points.ResultsDuring the study period, 89 patients were included in the analysis. The most commonly identified pathogen from the ascites cultures was Escherichia coli (65.2%), followed by Enterococcus spp. (51.7%). E. faecium was identified in 16 (18.0%) ascites samples. The microbiological profile of critically ill patients with LGP admitted to the ICU after surgery was similar to that of previous studies on intra-abdominal infection (IAI). Therefore, the initial empirical therapy in the IAI guidelines is more appropriate for LGP. Multivariate regression analysis suggested that the combination of initial empirical therapy with vancomycin was not associated with in-hospital mortality (odds ratio [OR] = 0.96, 95% confidence interval [CI] 0.23–3.00, p = 0.955), duration of ICU stay (coefficient=-0.92, 95% CI -3.04–1.21, p = 0.393), or duration of ventilator-support (coefficient=-9.03, 95%CI -49.69–31.63, p = 0.659).ConclusionThe microbiological profile of critically ill patients with LGP admitted to the ICU after surgery was similar to that of previous studies on IAI. However, the frequency of E. faecium in the present study was higher than that in previous studies. Initial empirical therapy with drugs such as meropenem in combination with vancomycin for E. faecium was not associated with in-hospital mortality, duration of ICU stay, and duration of ventilator support, after adjusting for confounding factors.

Chronic lower abdominal pain in an elderly female patient: a case report about sigmoid colon fistula and pelvic abdominal infection

An elderly woman patient presented with a history of recurrent right lower abdominal pain accompanied by fever and abnormal vaginal discharge for 36 years worse for two weeks. Conservative medical treatment was ineffective, by laparoscopic exploration combined with intraoperative colonoscopy, the presence of a sigmoid colon fistula and pelvic abdominal infection with foreign bodies were confirmed. It was hypothesized that the occurrence of recurrent right lower abdominal pain and intestinal fistula may be potentially associated with tubal injection sterilization performed 36 years ago.

Early Oral Step-Down Versus Continued Intravenous Antibiotic Treatment of Complicated Intra-Abdominal Infection.

Background: Complicated intra-abdominal infections (cIAIs) require a combined tactic, of source control and antimicrobial therapy. This study aimed to evaluate the safety and efficacy of oral step-down antimicrobial therapy in cIAIs after initial intravenous (IV) antimicrobial therapy. Methods: This retrospective cohort study included hospitalized adult patients diagnosed with a cIAI who received more than seven days of IV therapy from March 2017 to October 2021. Exclusion criteria included primary/peritoneal dialysis-related peritonitis, necrotizing pancreatitis, fistulizing inflammatory bowel disease, or upper gastrointestinal tract infection. Patients were assigned into two groups: IV-only or oral step-down therapy. The primary outcome was infection recurrence, defined as re-initiation of antimicrobial agents after a treatment-free period of more than or equal to three days. Secondary outcomes included treatment escalation, repeat source control procedure, treatment-related complications, and all-cause mortality. Results: The cohort consisted of 248 patients (199 IV-only and 49 oral step-down). Patients receiving IV-only therapy had a shorter median antimicrobial duration than the oral step-down group (13 vs. 23 d; p <0.0001). Infection recurrence occurred in 26 (13.1%) and 6 (12.2%) patients in the IV-only and oral step-down groups, respectively (p = 0.88). Treatment escalation, repeat source control, and 28-day mortality were similar between groups. Oral step-down therapy resulted in more adverse drug events (10.2% vs. 3.0%; p = 0.04). Discussion: Transition to oral step-down after initial IV therapy had a similar rate of infection recurrence as IV-only therapy but was associated with a longer duration of antimicrobial therapy and an increased rate of adverse drug reactions. Larger randomized non-inferiority studies are needed to confirm this approach.

Risk profile and thromboprophylaxis practices among patients undergoing laparotomy at Moi teaching and referral hospital

Background: Venous thromboembolism (VTE) significantly causes hospital mortality worldwide, with abdominal surgery a risk factor. Venous thromboprophylaxis can reduce VTE risk, but has adverse effects. Local research on risk profile and practice helps individualize thromboprophylaxis and develop local protocols. Methods: A prospective study was conducted at Moi teaching and referral hospital (MTRH) on adult laparotomy patients. The minimal sample size was 325 patients, using consecutive sampling. DVT was assessed using Well's score perioperatively, 2 weeks and 4 weeks postoperatively. A lower limb Doppler ultrasonography was performed on patients with a score of 2 or greater to rule out DVT. Results: The mean age of study participants was 38 years, with a 1.5:1 male-to-female ratio. Infection in the abdomen was the main reason for laparotomy. All procedures were open, and 75.4% of individuals had high or moderate VTE risk. Within 72 hours, 82.7% of patients were mobilized. Chemoprophylaxis was limited to enoxaparin post-op. Enoxaparin duration was unstandardized, and MTRH VTE risk categorization chart use was not reported. 3% of individuals received chemoprophylaxis against ACCP guidelines and 12% received enoxaparin despite contraindications. Only 13% and 24% of intermediate and high-risk patients got chemoprophylaxis. No mechanical prophylaxis was used. Symptomatic DVT was 6.8%. Advanced age, Caprini score, and enoxaparin prescription increased symptomatic DVT risk. Conclusions: Despite increased laparotomies for intra-abdominal infection and middle-aged patients, VTE is common in MTRH patients. Poor VTE risk stratification and MTRH protocol failure led to improper thromboprophylaxis. Prescribers should employ MTRH VTE regimen for proper prophylaxis. Providing prescribers with thromboprophylaxis choices to customize prescriptions.

Clinical characteristics, treatment strategy, and clinical outcomes in type 2 intestinal failure

Objective: To evaluate the characteristics, clinical management and clinical outcomes of type 2 intestinal failure (IF). Methods: A descriptive case-control study was carried out. The inclusion criteria were as follows: (1) the diagnosis of IF was performed according to the European Society for Parenteral and Enteral Nutrition (ESPEN) consensus statement. (2) using a requirement for parenteral nutrition (PN) of 28 days or more as surrogate marker. (3) a multidisciplinary team (MDT) included surgeons, nutritionist, pharmacist, stoma therapists, and critical care physicians. (4) complete laboratory data. Patients with type 1 and type 3 IF and those who do not cooperate with follow-up. All the data of 67 type II IF were collected from the database in Sir Run Run Shaw Hospital from Jan 2016 to Dec 2023. The pathophysiology, clinical management, and outcomes of type II IF were analyzed. Results: A total of 67 type II IF were included. The median age was 54 (15-83) with 43 males and 24 females. The body mass index was (17.5±3.8) kg/m2, the incidence of malnutrition was 67.2% (45/67), the incidence of sarcopenia was 74.6% (50/67), the median number of previous surgeries was 2.0 (1-13), and the median duration time of PN was 2.1 (1-12) months. The underlying disease of type 2 IF included 36 Crohn`s disease, 2 ulcerative colitis, 3 radiation enteritis, 2 intestinal Behcet's disease, 4 mesenteric infarction, 1 aggressive fibromatosis, 5 abdominal cocoon syndrome, 5 gastrointestinal perforation, 1 hernia, 4 intestinal dysmotility, and 4 other reasons (gastrointestinal tumor, trauma, and non-Hodgkin's lymphoma). According to the pathophysiology of IF, there were 33 intestinal fistula, 12 intestinal dysmotility, 6 mechanical obstruction, 13 short bowel syndrome, and 3 extensive small bowel mucosal disease. After treatment with MDT, 67 patients with type 2 IF received nutritional support therapy for intestinal rehabilitation treatment, of which 36 patients recovered with oral diet or enteral nutrition, 31 patients underwent reconstructive surgery after intestinal rehabilitation treatment failure. The median duration time of reconstructive surgery was 2.7 (1-9) months. 24 patients recovered intestinal autonomy after surgery, with 7 deaths, including 6 deaths due to abdominal infections and 1 case of intestinal dysmotility with abiotrophy and liver failure. Conclusion: Standardized multidisciplinary treatment plays an important role in type II intestinal failure, and it promotes patients with intestinal failure regain enteral autonomy.

Improving treatment plan and mental health in children with abdominal infection for broad-spectrum bacterial infections

BACKGROUND Pediatric abdominal infection is a common but serious disease that requires timely and effective treatment. In surgical treatment, accurate diagnosis and rational application of antibiotics are the keys to improving treatment effects. AIM To investigate the effect of broad-spectrum bacterial detection on postoperative antibiotic therapy. METHODS A total of 100 children with abdominal infection who received surgical treatment in our hospital from September 2020 to July 2021 were grouped. The observation group collected blood samples upon admission and sent them for broad-spectrum bacterial infection nucleic acid testing, and collected pus or exudate during the operation for bacterial culture and drug sensitivity testing; the control group only sent bacterial culture and drug sensitivity testing during the operation. RESULTS White blood cell count, C-reactive protein, procalcitonin, 3 days after surgery, showed better postoperative index than the control group (P &lt; 0.05). The hospital stay in the observation group was significantly shorter than that in the control group. The hospitalization cost in the observation group was significantly lower than that in the control group, and the difference between the two groups was statistically significant (P &lt; 0.05). CONCLUSION Early detection of broad-spectrum bacterial infection nucleic acids in pediatric abdominal infections can help identify pathogens sooner and guide the appropriate use of antibiotics, improving treatment outcomes and reducing medical costs to some extent.

Irinotecan hydrochloride liposome HR070803 in combination with 5-fluorouracil and leucovorin in locally advanced or metastatic pancreatic ductal adenocarcinoma following prior gemcitabine-based therapy (PAN-HEROIC-1): a phase 3 trial

Liposomal irinotecan has shown promising antitumor activity in patients with advanced or metastatic pancreatic ductal adenocarcinoma (PDAC) who have undergone prior gemcitabine-based therapies. This randomized, double-blind, parallel-controlled, multicenter phase 3 study (NCT05074589) assessed the efficacy and safety of liposomal irinotecan HR070803 combined with 5-fluorouracil (5-FU) and leucovorin (LV) in this patient population. Patients with unresectable, locally advanced, or metastatic PDAC who had previously received gemcitabine-based therapies were randomized 1:1 to receive either HR070803 (60 mg/m2 anhydrous irinotecan hydrochloride, equal to 56.5 mg/m2 free base) or placebo, both in combination with 5-FU (2000 mg/m2) and LV (200 mg/m2), all given intravenously every two weeks. The primary endpoint of the study was overall survival (OS). A total of 298 patients were enrolled and received HR070803 plus 5-FU/LV (HR070803 group, n = 149) or placebo plus 5-FU/LV (placebo group, n = 149). Median OS was significantly improved in the HR070803 group compared to the placebo group (7.4 months [95% CI 6.1–8.4] versus 5.0 months [95% CI 4.3–6.0]; HR 0.63 [95% CI 0.48–0.84]; two-sided p = 0.0019). The most common grade ≥ 3 adverse events in the HR070803 group were increased gamma-glutamyltransferase (19.0% versus 11.6% in placebo group) and decreased neutrophil count (12.9% versus 0 in placebo group). No treatment-related deaths occurred in the HR070803 group, while the placebo group reported one treatment-related death (abdominal infection). HR070803 in combination with 5-FU/LV has shown promising efficacy and manageable safety in advanced or metastatic PDAC in the second-line setting, representing a potential option in this patient population.

Unnecessary repetitions of C-reactive protein and leukocyte count at the emergency department observation unit contribute to higher hospital admission rates.

The aim of the present study was to assess the effect of repeated laboratory measurement of C-reactive protein (CRP) and leukocyte count on the decision whether to admit or dicharge the patient with localized infections who received antibiotics at the Emergency Department (ED) observation unit. Adult patients with respiratory, urinary tract and abdominal infections, observed at the ED after antibiotic administration, in whom repeated measurements of CRP and leukocyte count were performed within 24 h, were included. They were initially grouped as planned discharge, planned admission and unclear attitude towards admission. Initial and repeated CRP and leukocyte count results, clinical dynamics (improvement, worsening, unchanged) and clinical decision about discharge or admission, were recorded. A total of 1,038 patients were eligible for inclusion. No significant differences in initial CRP and leukocyte count values were observed, nor any association of CRP and leukocyte count changes with clinical dynamics. Among 504 patients eligible for discharge at second laboratory sampling according to clinical dynamics, 54.4 % were further observed or admitted. Discharged patients had an average negative absolute (p<0.001) and relative CRP change (p=0.002). Clinical dynamics, first and second CRP results and absolute CRP change were independently associated with the decision to discharge or further observe/admit. Schematic repetitions of CRP and leukocyte count at the ED observation unit are common, regardless of patients' clinical condition. Clinical judgment remains the main guiding factor to admit or discharge the patient, but repeated CRP testing influences the final decision, contributing to higher admission rates.

Ten-year experience of laparoscopic partial splenectomy for patients with splenic benign lesions

BackgroundThe increasing comprehension of spleen function has led to the gradual endorsement of laparoscopic partial splenectomy (LPS) as a treatment option for benign spleen lesions. However, it is important to note that the LPS technique remains challenging. This study explores the standardized process and surgical techniques in LPS, aiming to promote the application of this technique. MethodsThe clinical data of 20 patients with benign cystic or solid spleen lesions who underwent LPS at Shunde Hospital, Southern Medical University were retrospectively collected. Data include age, gender, imaging data, surgical process, and postoperative complications. Additionally, the surgical techniques and standardization process were recorded in detail. ResultsAll 20 cases completed LPS without conversion to laparotomy or splenectomy. The surgical time was 162.25 ± 37.96 min, the intraoperative blood loss was 93.00 ± 58.40 mL, no blood products were transfused during the operations, and the removed volume of the spleen was about 34.75 ± 12.19 %. There were no postoperative complications such as intra-abdominal bleeding, intra-abdominal infection, pancreatic fistula, and residual splenic infarction. Postoperative pleural effusion occurred in four cases, and symptoms improved after symptomatic treatment. The postoperative hospital stay was 7.0 ± 1.4 days. There were no perioperative deaths. The residual splenic vessels were normal during the follow-up period, and no vascular embolism occurred. ConclusionsLPS is a safe, feasible, and effective surgical method for patients with benign cystic or solid spleen lesions. Subsequently, mastering related surgical techniques and standardized surgical procedures can control the surgical risks in suitable cases, making LPS the standard procedure for treating benign spleen diseases.

Central Nervous System Infections in Patients With Ventriculoperitoneal Shunts Admitted for Primary Abdominal Infections: A US Nationwide Cohort Analysis.

Although ventriculoperitoneal (VP) shunts are a common treatment for hydrocephalus, there are complication risks including infections. Late complications such as ventriculitis from ascending abdominal infections can have severe consequences. However, the incidence of central nervous system (CNS) infections in VP shunt patients with abdominal infections is not well understood. We aimed to determine the incidence of CNS infections in VP shunt patients admitted with abdominal infections. Using the National Inpatient Sample, we studied patients from 2016 to 2019 to determine the incidence of CNS infections in VP shunt patients admitted with abdominal infections. Results were compared with VP shunt patients admitted for primary pneumonia. Among 725 VP shunt patients presenting with abdominal infections, 20 (2.8%) had CNS infections. Chronic obstructive pulmonary disease, hypertension, older age, and a smoking history were more common in patients with CNS infections and primary abdominal infection (P < .05). Patients who developed CNS infection had a significantly higher likelihood of both blood transfusion and coma but a lower likelihood of seizures. VP shunt patients with CNS infections were more likely to undergo shunt removal (odds ratio [OR] = 23.167, P < .001). 4.1% of VP shunt patients with primary abdominal infections died during admission. In a population of primary abdominal infection and pneumonia patients with VP shunts, a multivariate logistic regression analysis controlling for age, sex, and comorbidities identified abdominal infection as an independent risk factor for both CNS infection (OR = 51.208, P < .001) and inpatient death (OR = 3.417, P < .001). Among 6620 VP shunt patients admitted with primary pneumonia, only 5 (0.1%) had CNS infection compared with 20 (2.8%) in those with a primary abdominal infection (OR = 37.532, P < .001), and mortality was 1.6% vs 4.1% for those with a primary abdominal infection (P < .05). CNS infections in VP-shunted patients with abdominal infections are relatively rare but may lead to increased risks of death and other serious adverse outcomes.

Amoebic Liver Abscess Multifocal with Bilateral Parapneumonic Effusion: A Case Report

A liver abscess is defined as a pus-filled mass in the liver that can develop from injury to the liver or an intraabdominal infection disseminated from the portal circulation. The majority of these abscesses are categorized into pyogenic or amoebic, although a minority is caused by parasites and fungi. Most amoebic infections are caused by Entamoeba histolytica. Complications of amoebic liver is abscess Pleuropulmonary involvement, which is reported in 20–30% of patients. A male patient, 53 years old, was admitted to Hospital for Upper right abdominal pain, Fever, Cough, Pain in the lower right chest. Chest examination found weakened bronchovesicular breath sounds as high as RIC V, Pleural Friction Rub, wet crackles. Abdominal Examination found supel palpation, liver palpable 2 fingers below the arcus costae and 2 fingers below the process xiphoid, blunt edge, soft consistency, tenderness pain in the dextra hypochondrium. Laboratory report Anti Amoeba : Positive 40,3 unit. The patient was given intravenous metronidazole therapy 3x750 mg for 10 days. Complications of Amoebic Liver Abscess is Pleuropulmonary involvement. Pulmonary and pleural amebiasis is an uncommon disease, usually occurring on the right side of the lung compared to the left side. Pulmonary amoebiasis is a life-threatening, but treatable, condition.

Effectiveness of temocillin in treatment of non-urinary tract infections caused by ESBL-producing Enterobacterales and risk factors for failure.

To describe the real-life use of temocillin for non-urinary tract infections, to assess its effectiveness in infections caused by ESBL-producing Enterobacterales, and to identify risk factors for treatment failure. Retrospective multicentric study in 14 tertiary care hospitals, including all patients who received at least one dose of temocillin for ESBL infections from 1 January 2016 to 31 December 2021 for non-urinary tract infections. Failure was a composite criterion defined within 28 day follow-up by persistence or reappearance of signs of infection, and/or switch to suppressive antibiotic treatment and/or death from infection. Logistic regression with univariable and multivariable analysis was performed to identify risks associated with failure. Data on 163 infection episodes were collected; 133 were due to ESBL-producing Enterobacterales and 128 were included in the effectiveness analysis. Median (IQR) age was 61 (53-70) years and 61.7% of patients were male. Main indications were lower respiratory tract infection (LRTI; 28.9%), intra-abdominal infections (IAI; 28.1%) and cutaneous infections (12.5%). The main bacteria involved were Klebsiella pneumoniae (48.4%), Escherichia coli (25.0%) and Enterobacter cloacae (24.2%). Polymicrobial infections occurred in 45.3% of cases. Temocillin was used as monotherapy in 86/128 (67.2%). Failure was found in 36/128 (28.1%) cases. In multivariable analysis, the only factor associated with failure was initial severity of the episode [adjusted OR 3.0 (95% CI: 1.06-8.69)]. During non-urinary tract infections, the main use of temocillin was for LRTIs and IAIs due to ESBL-producing E. coli and K. pneumoniae. The main risk factor for failure was initial severity of the disease.

Diagnostic utility of ultrasonography for thoracic and abdominal bacterial and parasitic diseases in ruminants: a comprehensive overview.

This review article describes the roles of ultrasound in assessing thoracic and abdominal infectious diseases, mainly bacterial and parasitic ones that affect farm animals, including cattle, camels, sheep, and goats. Ultrasonography is a non-invasive imaging technique used to diagnose infectious diseases affecting the cardiovascular, respiratory, digestive, urinary, and hepatobiliary systems. In cases of thoracic and abdominal infections, ultrasound typically reveals abnormalities in echogenicity and echotexture, the presence of unusual artifacts, and mass formation exerting pressure on surrounding structures. Inflammatory and degenerative changes within the viscera can be identified ultrasonographically by comparing the echogenicity of affected areas with that of the surrounding normal parenchyma, such as in fascioliasis. Bacterial and parasitic infections often result in capsular mass lesions with anechoic contents, as observed in hydatid cysts and cysticercosis, or varying echogenic contents, as observed in liver abscesses. Effusions within the pericardium, pleura, and peritoneum are common ultrasonographic findings in infectious thoracic and abdominal diseases. However, these effusions' echogenicity does not always allow for clear differentiation between transudates and exudates. The routine use of ultrasonography in the evaluation of the chest and abdomen in affected or suspected ruminants is highly beneficial for detection, guiding therapeutic decisions, assessing prognosis, and aiding in the eradication of highly contagious diseases that cause significant economic losses.

A nomogram prediction model for the risk of intra-abdominal infection after endoscopic full-thick resection of gastric submucosal tumors

BackgroundThis study aimed to investigate the risk factors for complication of intra-abdominal infection (IAI) after endoscopic full-thickness resection of gastric submucosal tumors (GSMT) and to establish a nomogram prediction model for the occurrence of IAI. MethodsClinical data of patients with GSMT who underwent endoscopic full-thick resection (EFR) from January 2018 to July 2023 were retrospectively analyzed. The patients were divided into IAI and non-IAI groups according to whether IAI occurred during postoperative hospitalization. Univariate and multivariate logistic regression analyses were performed on the relevant clinical data of patients in the two groups to screen the independent influencing factors for the occurrence of IAI. The nomogram model was constructed based on the independent influencing factors. Model discrimination was assessed by the area under the curve (AUC) of the receiver operating characteristic (ROC) curve. The consistency of model-predicted risk with actual risk was evaluated using the Hosmer-Lemeshow goodness-of-fit test. The clinical performance of the nomogram model was evaluated using decision curve analysis. ResultsA total of 240 GSMT patients who underwent EFR procedures were finally included in this study, including 14 patients (5.83%) in the IAI group and 226 patients in the non-IAI group. Univariate and multivariate logistic regression analyses showed that age (OR=1.283, 95% CI=1.029∼1.600), preoperative albumin (OR= 0.575, 95% CI=0.395∼0.837), duration of operation (OR=1.222, 95% CI=1.060-1.409), and hospitalization time (OR=4.089, 95% CI=1.190-14.043) were independent influencing factors for the incidence of IAI in GSMT patients undergoing EFR surgery (P < 0.05). A Nomogram model was established based on the above factors. The Hosmer ⁃ Lemeshow test value of this model was 4.230 (P=0.836). The AUC value of the predictive model was 0.992 (95% CI: 0.983 to 1.000), with a C-index of 0.992 (95% CI: 0.983-1.000), indicating that the nomogram model had good accuracy and discrimination. Decision curve analysis showed that the nomogram model had a good predictive performance. ConclusionsAge, preoperative albumin, duration of operation, and hospitalization time were independent influences on the occurrence of IAI in GSMT patients undergoing EFR surgery. A nomogram model based on these factors had a high predictive efficacy and may provide a guiding intervention for the prevention of postoperative IAI in GSMT patients.

Incisional hernia after major pancreatic resection: long term risk assessment from two distinct sources – A large multi-institutional network and a single high-volume center

BackgroundPost-operative incisional hernia (IH) is a common complication following abdominal surgery. Data regarding IH after major pancreatic surgery are limited. We aim to evaluate the long-term risk of IH following major pancreatic resection. MethodsA dual-approach study: a large multi-institutional research network (RN) was investigated for IH incidence and risk factors in propensity-score matched survivors after pancreaticoduodenectomy (PD) and distal pancreatectomy (DP), was complemented by a patient-reported questionnaire. ResultsRN analysis identified 22,113 patients that underwent pancreatic surgery. 11.0% of PD patients and 8.6% of DP patients developed IH (P < 0.0001). IH rates were higher with open surgery compared with minimally invasive approaches in PD (OR = 1.56, P = 0.03) and DP (OR = 1.94, P = 0.003). BMI>35 was found to correlate with increased IH rates for PD and DP (OR = 1.87, and OR = 1.86, respectively, P < 0.0001 each), as did postoperative intraabdominal infections (P < 0.0001). Patient-based survey of 104 patients, revealed that 16 patients (15%) reported post-operative IH during the follow-up period. BMI≥30, SSI and intra-abdominal abscesses were associated with increased IH risk (P < 0.05). ConclusionImproved survival after pancreatic resection has led to an increased prevalence of long-term surgical sequela. In this study, we demonstrate significant rates of IH among long-term survivors and assess potential risk factors.

Efficacy of HA380 hemoperfusion in the treatment of septic shock

Background: To evaluate the clinical efficacy of HA380 hemoperfusion (HP) in the treatment of septic shock. Methods: This study retrospectively analyzed the clinical data of patients with septic shock admitted to Ward II of the Department of Critical Care Medicine at the Shandong Provincial Hospital Affiliated to Shandong First Medical University from January 2022 to December 2023. These data included general information, temperature, heart rate (HR), mean arterial pressure (MAP), oxygenation index, norepinephrine (NE) dose, lactic acid, white blood cell count, neutrophil percentage, lymphocyte absolute value, procalcitonin (PCT), interleukin-6 (IL-6), acute physiology and chronic health evaluation II (APACHE II), sequential organ failure assessment (SOFA) before and after each blood perfusion (HA380), total hospital stay, intensive care unit (ICU) stay, and 28-day survival. Results: A total of 41 patients with septic shock were included in this study, consisting of 38 males and 3 females. According to their primary diseases, there were 18 cases of severe pneumonia, 16 cases of abdominal infection, 4 cases of bloodstream infection, 2 cases of urinary infection, and 1 case of soft tissue infection. At the time of inclusion, 33 patients underwent mechanical ventilation for respiratory support, and 4 patients were treated with extracorporeal membrane oxygenation. Statistically significant differences (all P &lt; 0.05) were observed in body temperature, HR, MAP, oxygenation index, norepinephrine dose, lactic acid, PCT, IL-6, creatinine (Cr), APACHE II, and SOFA before and after HP (HA380) treatment. According to the 28-day survival status of patients, patients were allocated into survival and death groups. The total hospital stay and ICU stay were statistically significantly different between the two groups (all P &lt; 0.05). Additionally, there were also statistically significant differences in APACHE II and SOFA before and after treatment (all P &lt; 0.05). Based on the severity stratification of IL-6 and PCT levels, it was observed that following HP (HA380) treatment, all subgroups showed varying degrees of improvement in SOFA and APACHE II scores (P &lt; 0.05). Conclusion: HP (HA380) can improve the clinical efficacy of patients with septic shock. In addition, this method improves hemodynamics, effectively reduces lactic acid levels and infection indexes, and alleviates organ function damage in patients with septic shock, which can strive for more time for subsequent treatment.

The efficacy and safety of single-incision plus one-port laparoscopic surgery vs. conventional five-port laparoscopic surgery for duodenum-preserving pancreatic head resection.

Single-incision plus one-port laparoscopic duodenum-preserving pancreatic head resection (SILDPPHR+1) is yet to be reported, and therefore, its safety and efficacy have yet to be established. This study aimed to assess the short-term efficacy of SILDPPHR+1 in comparison to conventional laparoscopic duodenum-preserving pancreatic head resection (cLDPPHR). Consecutive patients who underwent SILDPPHR+1 and cLDPPHR procedures were screened. An analysis of the intraoperative and postoperative data of all patients was carried out. Nineteen patients who underwent SILDPPHR+1 and 24 patients who underwent cLDPPHR at Sichuan Provincial People's Hospital from October 15, 2021, to October 30, 2023, were enrolled in this study. All baseline parameters of both groups were comparable. There was a statistically significant difference in the cosmetic score between the groups (P<0.001). No statistically significant differences were observed between the two groups regarding postoperative recovery, postoperative pancreatic fistula (POPF), bile leakage rate, delayed gastric emptying (DGE) rate, postpancreatectomy hemorrhage (PPH) rate, abdominal infection rate, or textbook outcomes. SILDPPHR+1 appears to be a reliable and safe procedure for certain patients, with no increase in the operating time or complications, similar to the results of cLDPPHR. Moreover, SILDPPHR+1 offers the added advantage of superior cosmetic results.

Surgical management of peritoneal metastases from appendix and colon cancer in patients with inflammatory bowel disease

BackgroundInflammatory bowel disease (IBD) may compromise outcomes of cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) for peritoneal metastases (PM) from appendix/colon cancer. We evaluated CRS/HIPEC outcomes in patients with concurrent IBD. MethodsA matched cohort study using a prospective institutional CRS/HIPEC database (1998–2023) included appendix/colon cancer patients with PM. We matched IBD patients to IBD-free controls in a 1:5 ratio with nearest-neighbor propensity score for sex, age, and peritoneal cancer index (PCI), and exact matching for prior CRS/HIPEC and primary tumor. Perioperative variables, including Clavien-Dindo 90-day complications, were compared. Kaplan-Meier overall (OS) and progression-free survival (PFS) were compared using stratified Cox regression. ResultsOf 605 CRS/HIPECs for appendix/colon cancer, 14 (2.3%) had concurrent Crohn’s disease (n = 6) or ulcerative colitis (n = 8). Seventy IBD-free controls were matched. Nine (64.7%) IBD patients had an appendix primary. Complete cytoreduction (CC-0/1) was achieved in 10 (71.4%) IBD and 57 (81.4%) IBD-free patients (p = 0.468). IBD vs IBD-free patients tended to have more grade-III/IV complications (35.7% [n = 5] vs 15.7% [n = 11], p = 0.082) and had a higher rate of severe nausea/vomiting (35.7% vs 4.3 %, p < 0.001) and diarrhea (28.6% vs 8.6%, p = 0.035). Rates of anastomotic leak (7.1% [n = 1] vs 1.4% [n = 1], p = 0.200) and intraabdominal infections (7.1% [n = 1] vs 2.9% [n = 2], p = 0.430) were similar for IBD vs IBD-free, respectively. IBD did not affect OS (HR [95% CI]: 1.1 [0.4, 2.9]) or PFS (HR [95% CI]: 1.2 [0.4, 3.9]). ConclusionIBD is associated with a higher rate of gastrointestinal complications after CRS/HIPEC for appendix/colon cancer; however, it does not affect OS or PFS.

Ceftazidime-Avibactam Treatment for Carbapenemase-Producing Enterobacterales in a South African Children's Hospital.

This study describes ceftazidime-avibactam use in 17 young children from a resource-constrained country, where intra-abdominal infection was common. All-cause mortality was 53%. Earlier initiation, dose optimization, recording infusion times, and reviewing the need for additional antibiotics were identified as easy-to-implement-antimicrobial-stewardship interventions.
