Applicability of sodium butyrate preparations from a surgeon's and gastroenterologist's perspective.

In recent years, much has been written about the possibilities of using exogenous sodium butyrate in the prevention and treatment of gastrointestinal diseases, in prehabilitation, in peri- and postoperative treatment, as well as its local application. It became possible thanks to the development of a special formulation (microencapsulation technique) enabling the delivery of unstable butyrate compounds to the large intestine, where it is used primarily as a source of energy. It also plays a key role in maintaining body homeostasis by maintaining the integrity of the intestinal epithelium and stimulating the intestinal immune system. There is growing evidence of the effectiveness of sodium butyrate in various areas of health. The following article discusses the possibilities of using microencapsulated sodium butyrate in the prevention and treatment of gastrointestinal diseases from the perspective of a gastroenterologist and gastrointestinal surgeon.

Persistent and newly developed gastrointestinal symptoms after surgery for intestinal malrotation in children: Dysmotility or disorders of gut and brain interaction?

OBJECTIVES: Surgery for intestinal malrotation (IM) aims to correct the defect and improve symptoms; however, many have persistent gastrointestinal (GI) symptoms postoperatively. We evaluated the incidence, clinical presentation, and long-term outcomes of children with surgically repaired IM and its possible association with disorders of gut and brain interaction (DGBI). METHODS: Multicenter retrospective study was conducted in patients from 0 to 21 years old, who had surgery for IM from 2000 to 2021 across three pediatric tertiary care centers. Data analyzed included demographics, time to diagnosis, idiopathic diagnosis, incidental diagnosis, postoperative follow-up, surgical time, and the need for surgery including bowel detorsion. Outcome variables were the presence of postoperative GI symptoms and DGBIs, and overall resolution of symptoms. We also evaluated the potential association of demographics and other included variables with our outcome variables. RESULTS: Ninety-two patients with surgically corrected IM were included, 54% were male, and median age of diagnosis and surgical correction was 4.9 and 7.8 months, respectively. Median follow-up after surgery was 64 months. A total of 77% had postoperative GI symptoms, and notably, 78% of patients without symptoms before surgery (incidental diagnosis) developed GI symptoms postoperatively and 27% of patients met Rome IV criteria for a one or more DGBI. No factors were associated to the presence of postoperative symptoms or DGBIs in multivariate analysis. Female gender was the only factor associated with lack of resolution of symptoms at follow-up. CONCLUSION: Pediatric IM is commonly associated with postoperative GI symptoms and DGBI well beyond surgery. An increased awareness about the prevalence of DGBI in these patients may help reach a prompt and accurate diagnosis, and improve their quality of life.

Abdominal computed tomography and exploratory laparotomy have high agreement in dogs with surgical disease.

OBJECTIVE: To compare the results of abdominal CT with exploratory laparotomy in the dog. ANIMALS: 100 client-owned dogs from 1 academic institution. METHODS: Medical records were searched for dogs that had undergone a preoperative abdominal CT scan read by a board-certified veterinary radiologist followed by an exploratory laparotomy. CT and surgical reports were compared. RESULTS: The overall agreement between abdominal CT scan and exploratory laparotomy in all cases was 97%. Overall, there was no evidence that proportion agreement differed on the basis of body condition score, time interval between CT and surgery, or oncologic versus nononcologic disease. CLINICAL RELEVANCE: Abdominal CT scan read by a board-certified diplomate is a sensitive presurgical diagnostic tool for surgical abdominal disease in the dog. When performing a specific abdominal surgery, it is acceptable for the surgeon to fully explore the abdomen or forego it for a smaller approach to the organ of interest if an abdominal CT was performed prior.

Persistent urinary incontinence in female Golden Retrievers following laser ablation of intramural ectopic ureters may be associated with the presence of historical urinary tract infection.

OBJECTIVE: To identify predictive factors for postoperative continence in female Golden Retrievers following cystoscopic-guided laser ablation of intramural ectopic ureters (CLA-EU). ANIMALS: 41 client-owned female entire Golden Retrievers with uni- or bilateral intramural ectopic ureter(s) were retrospectively enrolled. METHODS: Patients were diagnosed with ectopic ureters with a combination of ultrasonography and cystoscopy. CLA-EU was performed for all dogs so that each ureteral opening was considered to be in an appropriate position by a single operator. All dogs had short-term follow-up 4 weeks and long-term follow up > 10 weeks after the procedure via telephone, which included urinary continence scoring. Clinical factors and ultrasonographic and cystoscopic findings from initial presentation were evaluated to identify predictive factors for postoperative continence. RESULTS: Short-term urinary continence was achieved in 46.3% of dogs with no additional medical therapies. Presence of historical urinary tract infections prior to CLA-EU (OR, 0.130; 95% CI, 0.020 to 0.621; P = .018) was negatively correlated and ureteral dilatation (OR, 34.260; 95% CI, 1.813 to 2,143; P = .043) was positively correlated with likelihood of urinary continence. Long-term urinary continence was achieved in 63.4% of dogs, and presence of historical urinary tract infections was negatively prognostic (OR, 0.173; 95% CI, 0.023 to 0.856; P = .048). CLINICAL RELEVANCE: Female Golden Retrievers undergoing CLA-EU have similar outcomes to those reported for other mixed-breed cohorts with > 30% of dogs failing to regain urinary continence. Historical urinary tract infections were significantly associated with both short- and long-term urinary continence in our population.

Feasibility of S-1 adjuvant chemotherapy after major hepatectomy for biliary tract cancers: An exploratory subset analysis of JCOG1202.

INTRODUCTION: Major hepatectomy (MH) may produce the impaired liver function and affect the feasibility of adjuvant chemotherapy in terms of early period after the surgery, but there have not been detailed investigations. JCOG1202 (UMIN000011688) is a randomized phase III trial demonstrating the superiority of adjuvant S-1 chemotherapy for biliary tract cancer (BTC). The aim of this study is to examine the influence of MH for BTC on adjuvant S-1. MATERIALS AND METHODS: Of the total 424 patients, 207 received S-1 (S-1 arm) while the remaining 217 were not. We compared MH with non-major hepatectomy (NMH) for BTC. RESULTS: In the S-1 arm, 42 had undergone MH, and 165 had undergone NMH. MH had similar pretreatment features to NMH, including the proportion of biliary reconstruction, to NMH, except for a lower platelet count (17.7 vs. 23.4 × 104/mm3, p < 0.0001) and lower serum albumin level (3.5 vs. 3.8 g/dL, p < 0.0001). The treatment completion proportion tended to be lower for MH than for NMH (59.5 % vs. 75.8 %; risk ratio, 0.786 [95 % confidence interval, 0.603-1.023], p = 0.0733), and the median dose intensity was lower as well (88.7 % vs. 99.6 %, p = 0.0358). The major reasons for discontinuation were biliary tract infections and gastrointestinal disorders after MH. The frequency of grade 3-4 biliary tract infection was 19.0 % in MH vs. 4.2 % in NMH. CONCLUSION: The treatment completion proportion and dose intensity were lower in MH than in NMH. Caution should be exercised against biliary tract infections and gastrointestinal disorders during adjuvant S-1 after MH for BTC.

Regular use of low-dose of opioids after gastrointestinal surgery may lead to postoperative gastrointestinal tract dysfunction in children: a Chinese national regional health center experience sharing.

BACKGROUND: The need for pain management is increasing in pediatrics, but the side effects of overuse or abuse of analgesics can be harmful to children's health and even life-threatening in severe cases. METHODS: Patients who underwent resection of Meckel's diverticulum at the Children's Hospital of Chongqing Medical University from July 1, 2019, to July 1, 2022, were included in this study. Opioids were administered through patient-controlled analgesia (PCA). Based on the preoperative choices made by the legal guardians, patients were stratified into two groups: PCA Group (PCAG) and Non-PCA Group (NPCAG). Data pertaining to the clinical characteristics and prognoses of these patients were subsequently collected and analyzed to assess the impact of opioid administration. RESULTS: In the study, a total of 126 patients were enrolled, with 72 allocated to the Patient-Controlled Analgesia Group (PCAG) and 54 to the Non-Patient-Controlled Analgesia Group (NPCAG). When compared to the NPCAG, the PCAG exhibited a longer duration of postoperative fasting (median 72 vs. 62 h, p = 0.044) and increased utilization of laxatives (12[16.7%] vs. 2[3.7%], p = 0.022). However, the PCAG also experienced higher incidences of intestinal stasis and abnormal intestinal dilation (13[18.1%] vs. 3[5.6%], p = 0.037). No statistically significant differences were observed in pain assessments at the conclusion of the surgical procedure (0 vs. 1[1.9%], p = 0.429) or within the first 24 h postoperatively (16[22.2%] vs. 18[33.3%], p = 0.164). Additionally, NPCAG patients did not necessitate increased administration of rescue analgesics (2[2.8%] vs. 4[7.4%], p = 0.432). CONCLUSIONS: The administration of opioids did not demonstrably ameliorate postoperative pain but was associated with a heightened incidence of postoperative gastrointestinal tract dysfunction. The retrospective nature of the current research should be considered and should be clarified further.

Fisioterapia temprana, funcionalidad y complicaciones postoperatorias en adultos con cirugía abdominal de urgencia / Early physiotherapy, functionality, and postoperative complications in adults undergoing emergency abdominal surgery

Introducción Se desconoce la importancia del acceso temprano a la fisioterapia (FT) en personas sometidas a cirugía abdominal de urgencia, por lo tanto este estudio se enfocó en determinar la efectividad de la FT temprana versus tardía en la mejora de niveles funcionales y reducción de complicaciones postoperatorias (CP) en adultos sometidos a este procedimiento. Metodología Estudio retrospectivo que incluyó a 132 pacientes ingresados por cirugía abdominal de urgencia. Se registró el inicio de FT (temprana vs. tardía), se evaluó la funcionalidad mediante índice de Barthel y la puntuación acumulada de deambulación (CAS), las CP y la duración de la estancia hospitalaria. Resultados Las personas que recibieron FT temprana exhibieron CP de menor gravedad (p=0,012). Asimismo, el grupo con FT temprana tuvo estancias hospitalarias más cortas (mediana=10 vs. 17 días; p=0,0001). Adicionalmente, se observó que la funcionalidad intrahospitalaria disminuyó respecto a valores prehospitalarios (índice de Barthel y CAS), mientras que al alta se observaron incrementos parciales, sin diferencias entre los grupos que recibieron FT temprana o tardía. Sin embargo, el grupo con FT temprana requirió un menor número de sesiones de FT motora (p=0,04). Conclusión En el presente estudio el desarrollo de CP de menor gravedad, menores estancias hospitalarias y una menor necesidad de FT motora fue observada en pacientes sometidos a cirugía abdominal de urgencia que recibieron FT temprana respecto a tardía. Esto sugiere que la FT temprana en este contexto optimizaría los recursos asociados a la atención en salud, mejorando además el proceso posquirúrgico en estos pacientes (AU)

Introduction Given that the relevancy of early physiotherapy (PT) in persons undergoing emergency abdominal surgery is unknown, this study aimed to determine the effectiveness of early versus late physiotherapy in improving functional levels and reducing postoperative complications (PC) in adults undergoing this procedure. Methodology Longitudinal retrospective study which included a sample of 132 patients admitted for emergency abdominal surgery. Functionality was evaluated using the Barthel index and the cumulated ambulation score (CAS). In addition, the type of PT (early vs. late) and the date of its onset were recorded, the PC during the hospital stay and the length of stay were recorded. Results Patients that received early PT exhibited less severe postoperative complications (p=0.012). Moreover, this group had a shorter length of stay (median=10 vs. 17 days; p=0.0001). In addition, in terms of functionality, decreases were observed during hospitalization compared with baseline levels (Barthel index and CAS), whereas a partial increase was observed at discharge, without differences between the patients that received early PT or not. Nevertheless, the early PT group required a lower number of PT sessions (p=0.04). Conclusion In this study, a less severe postoperative complications rate, shorter length of stay, and lower necessity of PT sessions were observed in adults undergoing emergency abdominal surgery that received early PT versus late PT. This suggests that early PT in this context would optimize health care resources, improving the postoperative process in these patients (AU)

Incidence and risk factors for postoperative gastrointestinal dysfunction occurrence after gastrointestinal procedures in US patients.

BACKGROUND: Incidence of, and potential risk factors for, postoperative gastrointestinal dysfunction (POGD) after gastrointestinal procedures performed in US hospitals were examined. METHODS: This retrospective study used hospital discharge data of inpatients who underwent ≥1 gastrointestinal procedures from 1-Jan-2016 to 30-Apr-2019. POGD incidence was calculated based on all hospitalizations for MDC-06 procedures. Predictors of POGD were assessed using multivariable logistic regression. RESULTS: POGD incidence was 5.8% among 638 611 inpatient hospitalizations. Major bowel procedures, peritoneal adhesiolysis, and appendectomy were the most notable predictors of POGD among gastrointestinal procedures assessed (adjusted odds ratios [95% confidence intervals]: 2.71 [2.59-2.83], 2.48 [2.34-2.64], and 2.15 [2.03-2.27], respectively; all p < 0.05). Procedures performed by colorectal/gastroenterology specialists (0.86 [0.84-0.89]), and those performed percutaneously (0.55 [0.54-0.56]) were associated with significantly lower odds of POGD (both P < 0.05). CONCLUSIONS: Findings may help clinicians tailor management plans targeting patients at high-risk of POGD.

The effect of dexmedetomidine on the post operation recovery of gastrointestinal function undergoing intestinal surgery: implications for retired athletes

Objective: To investigate the effect of dexmedetomidine on the recovery of gastrointestinal function after intestinal surgery. Methods: A total of 94 cases of gastrointestinal endoscopic surgery in our hospital from February 2020 to April 2022 were selected and randomly divided into dexmedetomidine group (group D, n=47) and control group (group C, n=47), There is no restriction on gender and age. Group E was given 1 μg/kg of dexmedetomidine before induction of anesthesia, and 0.5 μg/kg.h was pumped during the maintenance period of anesthesia. Group C was given an equal volume of normal saline. Heart rate (HR) and mean arterial pressure (MAP) were recorded at five time points before anesthesia (T0), after intubation (T1), skin incision (T2), after skin incision 1h (T3), and at the end of surgery (T4). BIS, intraoperative dosage of propofol and remifentanil, VAS score and Ramsay sedation score at 24h, 48h, 72h after operation, I-FEED scoreand bowel sound recovery time at 24h, 48h, 72h, 96h after operation, exhaust time, eating time, defecation time, and discharge time. Results: Compared with group C, the MAP and HR of group D were more stable, the consumption of anesthetics in group D was significantly lower, and the VAS score of group E was lower than that of group C at 24, 48, and 72 hours after operation (P<0.05). The I-FEED score at 24h, 48h, 72h, and 96h after operation and the incidence of PONV and POGD in group D were lower than those in group C (P＜0.05). Postoperative bowel sounds recovery time, exhaust time, eating time, defecation time and hospitalization days in group D were lower than those in group C, and the difference was statistically significant (P<0.05). Conclusion: Dexmedetomidine is applied in intestinal surgery, it can stabilize the induction period and intraoperative hemodynamics, reduce the amount intraoperative anesthetics, promote the recovery of gastrointestinal function, and accelerate the recovery of athletic patients.

Lumen-apposing metal stents for the treatment of benign gastrointestinal tract strictures: a single-center experience and proposed treatment algorithm.

BACKGROUND: Lumen-apposing metal stents (LAMS) are an alternative therapeutic option for benign gastrointestinal (GI) tract strictures. Our study aimed to evaluate the safety and efficacy of LAMS for the management of benign GI strictures. METHODS: Consecutive patients who underwent a LAMS placement for benign luminal GI strictures at a tertiary care center between January 2014 and July 2021 were reviewed. Primary outcomes included technical success, early clinical success, and adverse events (AEs). Other outcomes included rates of stent migration and re-intervention after LAMS removal. RESULTS: One hundred and nine patients who underwent 128 LAMS placements (67.9% female, mean age of 54.3 ± 14.2 years) were included, and 70.6% of the patients had failed prior endoscopic treatments. The majority of strictures (83.5%) were anastomotic, and the most common stricture site was the gastrojejunal anastomosis (65.9%). Technical success was achieved in 100% of procedures, while early clinical success was achieved in 98.4%. The overall stent-related AE rate was 25%. The migration rate was 27.3% (35/128). Of these, five stents were successfully repositioned endoscopically. The median stent dwell time was 119 days [interquartile range (IQR) 68-189 days], and the median follow-up duration was 668.5 days [IQR: 285.5-1441.5 days]. The re-intervention rate after LAMS removal was 58.3%. CONCLUSIONS: LAMS is an effective therapeutic option for benign GI strictures, offering high technical and early clinical success. However, the re-intervention rate after LAMS removal was high. In select cases, using LAMS placement as destination therapy with close surveillance is a reasonable option.

Characterizing gastrointestinal dysfunction after pancreatic resection: a single-center retrospective study.

BACKGROUND: There are many well-described potential gastrointestinal (GI) side effects of pancreatic resection that can cause patients to suffer from chronic malabsorption, diarrhea, and persistent nausea. These GI symptoms can affect postoperative recovery, initiation of adjuvant therapy, and overall quality of life (QOL). The purpose of this study is to quantify the incidence of post-procedural complications and identify patients at higher risk for experiencing GI dysfunction after pancreatectomy. METHODS: A retrospective review of patients who underwent pancreatic resection at a single institution between January 2014 and December 2019 was performed. Demographics, operative factors, and postoperative gastrointestinal symptomatology and treatments were obtained by chart review. Significance tests were performed to compare GI dysfunction between patient subgroups. RESULTS: A total of 545 patients underwent pancreatic resection; within the cohort 451 patients (83%) underwent a pancreaticoduodenectomy (PD) and the most common indication was pancreatic adenocarcinoma. Two-thirds of patients (67%) reported gastrointestinal symptoms persisting beyond hospitalization. Only 105 patients (20%) were referred to gastroenterology for evaluation with 30 patients (5.5%) receiving a formal diagnosis. Patients who underwent PD were more likely to report GI symptoms and patients who identified as Caucasian were more likely to be referred to gastroenterology for evaluation. CONCLUSIONS: Gastrointestinal dysfunction after pancreatic resection occurs frequently yet only a small percentage of patients are referred for formal testing and diagnosis. There also appears to be a racial difference in referral patterns. Patients would benefit if earlier attention was dedicated to the diagnosis and corresponding treatment for postoperative digestive health disorders to optimize treatment planning and QOL.

Primary repair of nonsteroidal anti-inflammatory drug-associated full thickness gastrointestinal ulcers in 11 dogs.

OBJECTIVE: To report the outcomes of dogs that underwent primary repair of gastroduodenal perforations associated with the administration of nonsteroidal anti-inflammatory drugs (NSAID). A secondary objective was to identify clinicopathological findings that predisposed dogs to postoperative death. STUDY DESIGN: Retrospective study. ANIMALS: Eleven dogs with complete gastric or duodenal perforation related to administration of an NSAID that underwent primary surgical repair. METHODS: Medical records were reviewed for dogs that presented with peritonitis due to a complete gastroduodenal perforation while receiving NSAIDs between November, 2011 and January, 2021. Data collected included patient characteristics, clinical signs, clinicopathological results, surgical details, and postoperative management and outcome. RESULTS: All dogs were large breeds (mean weight 42 kg; range 22-75 kg), with a mean age of 7.35 years. Nine dogs from a total of 11 (82 %) received a concurrent corticosteroid and NSAID, or a higher dose/frequency/length of NSAID administration than recommended by the manufacturer. All gastroduodenal perforations were found in the upper gastrointestinal tract. Eight of 11 (73%) dogs survived to discharge. The median postoperative duration of follow up was 444 days (range 2-1460 days). No association was detected between ulcer size or location and mortality. CONCLUSION: Most dogs who underwent primary repair of complete gastroduodenal ulcers survived. Gastroduodenal perforations were generally due to the administration of higher or longer doses of NSAIDs, or concurrent administration of another NSAID or corticosteroid. CLINICAL SIGNIFICANCE: Primary closure may be associated with a high success rate in dogs with full thickness gastroduodenal ulcers.
