RESUMO
BACKGROUND: Intra-abdominal bleeding resulting from inadequate drainage of duodenal leakage (DL) is typically caused by the corrosiveness of duodenal fluid. Open abdomen (OA) treatment addresses both the drainage and bleeding simultaneously. However, a sequential treatment (ST) approach involving hemostasis through transcatheter arterial embolization (TAE) followed by percutaneous drainage of source control has emerged as an alternative method. This study aimed to evaluate the prognosis of ST in cases of DL-induced intra-abdominal bleeding. METHODS: This retrospective cohort study included 151 participants diagnosed with DL-induced intra-abdominal bleeding from January 2004 to December 2010, and January 2013 to December 2021. The ST and OA groups were established based on the treatment method applied. Propensity score-matching (PSM) matched patients in the ST group with those in the OA group. RESULTS: Among the 151 patients, 61 (40.4%) died within 90 days after the bleeding episode. ST was associated with a lower mortality rate (28.2% vs. 51.3% adjusted odds ratio [OR] = 0.34; 95% confidence interval [CI] 0.17-0.68; P = 0.003) compared to OA. Following PSM, ST remained the only factor associated with reduced mortality (OR = 0.32; 95% CI 0.13-0.75; P = 0.009). Moreover, ST demonstrated a higher rate of initial hemostasis success before (90.1% [64/71] vs. 77.5% [62/80]; adjusted OR = 2.84; 95% CI 1.07-7.60; P = 0.04) and after PSM (94.4% [51/54] vs. 77.8% [42/54], adjusted OR = 3.85; 95% CI 2.15-16.82; P = 0.04). Additionally, ST was associated with a lower incidence of rebleeding within 90 days after the initial bleeding, before (7 vs. 23; adjusted OR 0.41; 95% CI 0.18-0.92; P = 0.03) and after PSM (5 vs. 14; adjusted OR 0.37; 95% CI 0.15-0.93; P = 0.03). CONCLUSIONS: Applying ST involving TAE and subsequent percutaneous drainage might be superior to OA in lowering the mortality in DL-induced intra-abdominal hemorrhage.

PURPOSE: The present study aimed to identify the predictive value of duration of postoperative hyperlactatemia in screening patients at high risk of recurrent fistula after major definitive surgery (DS) for intestinal fistula. METHODS: If the initial postoperative lactate (IPL) > 2 mmol/L, DS was defined as major definitive surgery. The 315 enrolled patients with major DS were divided into group A (2 mmol/L < IPL ≤ 4 mmol/L), group B (mmol/L < IPL ≤ 6 mmol/L), and group C (IPL > 6 mmol/L). The characteristics of patients were collected, and the duration of postoperative hyperlactatemia was analyzed. According to the occurrence of recurrent fistula (RF), patients were further divided into RF group A, and Non-RF group A; RF group B, and Non-RF group B; and RF group C, and Non-RF group C. RESULTS: The duration of postoperative hyperlactatemia was comparable between the RF group A and the Non-RF group A [12 (IQR: 12-24) vs 24 (IQR: 12-24), p = 0.387]. However, the duration of hyperlactatemia was associated with RF in group B (adjusted OR = 1.061; 95% CI: 1.029-1.094; p < 0.001) and group C (adjusted OR = 1.059; 95% CI: 1.012-1.129; p = 0.017). In group B, the cutoff point of duration of 42 h had the optimal predictive value (area under ROC = 0.791, sensitivity = 0.717, specificity = 0.794, p < 0.001). In group C, the cutoff point of duration of 54 h had the optimal predictive value (area under ROC = 0.781, sensitivity = 0.730, specificity = 0.804, p < 0.001). CONCLUSION: The duration of postoperative hyperlactatemia has a value in predicting RF in patients with an IPL of more than 4 mmol/L after major definitive surgery for intestinal fistula.

OBJECTIVE: To summarize the genetic characteristics of 671 Chinese pedigrees affected with Duchenne/Becker muscular dystrophy (DMD/BMD). METHODS: Clinical data of the pedigrees were collected. Multiplex PCR, multiple ligation dependent probe amplification (MLPA), next generation sequencing (NGS), Sanger sequencing and long read sequencing were used to detect the variant of DMD gene in the probands and their mothers, and prenatal diagnosis was provided for high risk pregnant women. RESULTS: Among 178 pedigrees analyzed by multiplex PCR, 44 variants of the DMD gene were detected, with the genetic diagnosis attained in 110 pedigrees. Among 493 pedigrees analyzed by MLPA in combination with NGS or Sanger sequencing, 294 pathogenic/possible pathogenic variants were identified, among which 45 were unreported previously, and the genetic diagnosis attained in 484 pedigrees. Structural variants of the DMD gene were identified in two pedigrees by long-read sequencing. Among 444 probands, 341 have inherited the DMD gene variant from their mothers (76.8%). Among 390 women with a high-risk, 339 have opted to have natural pregnancy and 51 chose preimplantation genetic testing for monogenetic disease (PGT-M). The detection rate of neonatal patients and carriers following natural pregnancy was significantly higher than that for PGT-M. CONCLUSION: Combined application of MLPA, NGS, Sanger sequencing and long-read sequencing is an effective strategy to detect DMD/BMD. PGT-M can effectively reduce the risk of fetuses. Above finding has expanded the spectrum of DMD gene variants and provided a basis for reproductive intervention for pregnancies with a high risk for DMD/BMD.

OBJECTIVE: To analyze the (CGG)n repeats of FMR1 gene among patients with unexplained mental retardation. METHODS: For 201 patients with unexplained mental retardation, the (CGG)n repeats of the FMR1 gene were analyzed by PCR and FragilEaseTM PCR. Prenatal diagnosis was provided to carriers of pre- and full-mutations. The pattern of X chromosome inactivation (XCI) was determined for women with mental retardation and full mutations. RESULTS: For the 201 patients with unexplained mental retardation, 15 were identified with full mutations of the FMR1 gene. The prevalence of fragile X syndrome (FXS) in patients with unexplained mental retardation was determined as 7.5% (15/201). Prenatal diagnosis was provided for 6 pregnant women with pre- or full mutations. Analysis revealed that women with mental retardation and full FMR1 mutations exhibited a skewed XCI pattern with primary expression of the X chromosome carrying the mutant allele. CONCLUSION: FXS has a high incidence among patients with unexplained mental retardation. Analysis of FMR1 gene (CGG)n repeats in patients with unexplained mental retardation can facilitate genetic counseling and prenatal diagnosis for their families. FMR1 gene (CGG)n repeats screening should be recommended for patients with unexplained mental retardation.

Abdominal adhesions manifests following abdominal infections triggered by intestinal fistulas. The severity of such adhesions depends on the extent of fiber deposition and peritoneal fibrinolysis following peritoneal injury, which may be influenced by sustained inflammation within the abdominal cavity. In this regard, the visceral-to-subcutaneous fat area (VFA/SFA) ratio has been implicated as a potential marker of inflammation. This study aimed to explore the relationship between VFA/SFA and abdominal adhesions. This multicenter study was conducted across four tertiary institutions and involved patients who had undergone definitive surgery (DS) for intestinal fistula from January 2009 and October 2023. The presence of abdominal adhesions was determined intraoperatively. VFA/SFA was investigated as a potential risk factor for severe adhesions. The study comprised 414 patients with a median age of 50 [interquartile range (IQR) 35-66] years and a median body mass index of 20.0 (IQR 19.2-22.4) kg/m2, including 231 males with a median VFA/SFA of 1.0 (IQR 0.7-1.2) and 183 females a median VFA/SFA of 0.8 (0.6-1.1). VFA/SFA was associated with severe abdominal adhesions in males [odds ratio (OR) = 3.34, 95% CI 1.14-9.80, p = 0.03] and females (OR = 2.99, 95% CI 1.05-8.53, p = 0.04). J-shaped association between VFA/SFA ratio and severe adhesions was revealed in both sex. The increasing trend can be revealed when OR more than 0.8, and 0.6 in males and females respectively. Preoperative VFA/SFA demonstrates predictive value for statues of severe abdominal adhesions in DS for anastomotic fistula after small intestine resection.

PURPOSE: To evaluate the effect of postoperative utilization of somatostatin after definitive surgery for duodenal fistula (DF) in preventing a recurrence. METHODS: Patients with definitive surgery for DF between January 2010 and December 2021 were categorized based on the utilization of somatostatin or not after the surgery. Patients in the Somatostatin group were matched to those in the Non-somatostatin group using propensity scores matching (PSM), so as to evaluate the effect of postoperative use of somatostatin by comparing the two groups. RESULTS: A total of 154 patients were divided into the in the Somatostatin group (84) and the Non-somatostatin group (70). Forty-three patients (27.9%) exhibited a recurrent fistula, with which the postoperative use of somatostatin was not associated (19 [22.6%] in the Somatostatin group and 24 (34.3%) in the Non-somatostatin group; unadjusted OR 0.56; 95% CI 0.28-1.14; P = 0.11). However, the postoperative usage of somatostatin served as a protective factor for developing into high-output recurrent fistula (eight (13.3%) in the Somatostatin group and 15 (25%) in the Non-somatostatin group; adjusted OR 0.39; 95% CI 0.15-0.93; P = 0.04). After PSM, the recurrent fistula occurred in 29.2% subjects (35/120). The postoperative usage of somatostatin was not associated with recurrent fistula (13 in PSM Somatostatin group vs. 22 in PSM Non-somatostatin group; unadjusted OR 0.48; 95% CI 0.21-1.07; P = 0.07), while its postoperative usage decreased the incidence of recurrent high-output fistula (5/60 in the PSM Somatostatin group, compared with 13/60 in the PSM Non-somatostatin group; adjusted OR 0.30; 95% CI 0.09-0.95). CONCLUSION: Postoperative use of somatostatin could effectively reduce the incidence of recurrent high-output fistula, without association with overall incidence of postoperative recurrent fistula.

Background: To investigate the efficacy of an alternative negative pressure treatment for the treatment of enteroatmospheric fistula transformed from small intestinal leakage due to incision dehiscence after abdominal surgery. Methods: Patients with an enteroatmospheric fistula from small intestinal leakage owing to incision dehiscence following abdominal surgery between January 2010 and December 2019 were retrospectively reviewed. Results: A total of 83 patients (mean age: 38.3 ± 11.6 years; Body mass index: 19.9 ± 2.2 kg/m2) were enrolled. Of the 83 patients, 59 (71.1 %) achieved fistula closure. High-output fistula (Hazard ratio = 0.48; 95 % Confidence interval: 0.29-0.81; P = 0.006) and abdominal wall thickness >2 cm (Hazard ratio = 2.76; 95 % Confidence interval: 1.35-5.67; P = 0.006) were identified as factors affecting fistula closure. Lastly, 11/83 (13.3 %) patients exhibited re-dehiscence. Conclusion: Appropriately applying the alternative negative pressure treatment may enable fistula closure in patients with enteroatmospheric fistula resulting from small intestinal leakage caused by incision dehiscence.
RESUMO
Purpose: The purpose of this study is to compare the effect of preoperative predigested formula vs. polymeric formula on bowel function recovery following definitive surgery (DS) for small intestinal enteroatmospheric fistula (EAF). Methods: In this retrospective study, from January 2005 to December 2019, the patients with small intestinal EAF and receiving a DS were enrolled. During the preoperative treatment, each patient received enteral nutrition via nasojejunal feeding and chyme reinfusion. The enrolled subjects were classified into two groups, based on their formula type: polymeric formula and predigested formula. Then, propensity scores matching (PSM) was used to further divide these patients into PSM polymeric formula group or PSM predigested formula group. The clinical characteristics of the groups were analyzed. Result: A total of 137 patients were finally enrolled, with 72 patients in the polymeric formula group and 65 patients in predigested formula group. The postoperative ileus was manifested in a total of 61 (44.5%) cases, with 27 (37.5%) in the polymeric formula group and 34 (52.3%) in the predigested formula group (P = 0.04). It was predicted that the polymeric formula could result in a reduction in postoperative ileus (OR = 0.47; 95% CI: 0.21-0.95; P = 0.04). After 1:1 PSM, there were 110 patients included. The postoperative ileus was observed in 47 patients, with 18 (32.7%) in the polymeric formula group and 29 (52.7%) in the predigested formula group (P = 0.03). After PSM, the polymeric formula demonstrated a reduction in the incidence of postoperative ileus (OR = 0.42; 95% CI: 0.19-0.92; P = 0.03). Conclusion: Compared with predigested formula, the preoperative polymeric formula appears to be associated with earlier recovery of bowel function after DS for EAF.
RESUMO
Purpose: This study is aimed to reveal the role of preoperative chyme reinfusion (CR) in reducing the complications occurring after definitive surgery (DS) for small intestinal enteroatmospheric fistula (EAF). Methods: In this study, from January 2012 to December 2019, the patients with small intestinal EAF and receiving a definitive surgery were recruited. Depending on whether the CR has been performed, these patients were divided into either the CR group or the non-CR group. Then, propensity scores matching (PSM) was used to further divide these patients into the PSM CR group or the PSM none-CR group. The clinical characteristics exhibited by the groups were analyzed, and the effect of preoperative CR was investigated. Result: A total of 159 patients were finally recruited with 72 patients in the CR group and 87 patients in the non-CR group. The postoperative complications were manifested in a total of 126 cases (79.3%). There were 49 cases in the CR group, and 77 cases in the non-CR group. CR was associated with the occurrence of postoperative complications (multivariate odds ratio [OR] = 0.289; 95% CI: 0.123-0.733; p = 0.006). After 1:1 PSM, there were 92 patients included. The postoperative complications were observed in 67 out of these 92 patients. There were 26 patients in the PSM CR group, and 41 patients in the PSM non-CR group. CR was associated with postoperative complications (multivariate OR = 0.161; 95% CI: 0.040-0.591; p = 0.002). In addition, CR played a role in reducing the recurrence of fistula both before (multivariate OR = 0.382; 95% CI: 0.174-0.839; p = 0.017) and after (multivariate OR = 0.223; 95% CI: 0.064-0.983; p = 0.034) PSM. In addition, there is a protective factor at play for those patients with postoperative ileus before (multivariate OR = 0.209; 95% CI: 0.095-0.437; p < 0.001) and after (multivariate OR = 0.222; 95% CI: 0.089-0.524; p < 0.001) PSM. However, the relationship between CR and incision-related complications was not observed in this study. Conclusion: Preoperative CR is effective in reducing postoperative complications after definitive surgery was performed for EAF.
