Feasibility of Gastrografin Use for Adhesive Small Bowel Obstruction in Low-Income Countries.

INTRODUCTION: Small bowel obstruction (SBO) is one of the most common causes for hospital admission in Ethiopia. The use of water-soluble contrast agents (WSCAs) such as Gastrografin to manage adhesive SBO can predict nonoperative resolution of SBO and reduce decision time to surgery and length of hospital stay. However, nothing is known about practice patterns and Gastrografin use in low-income settings. We sought to characterize current management practices, including use of WSCAs, as well as outcomes for patients with SBO in Addis Ababa, Ethiopia. METHODS: We conducted a mixed-methods study consisting of a survey of surgeons throughout Ethiopia and a retrospective record review at five public, tertiary care-level teaching hospitals in Addis Ababa. RESULTS: Of the 76 surgeons who completed the survey, 63% had heard of the use of WSCAs for SBO and only 11% used oral agents for its management. Chart review of 149 patients admitted with SBO showed the most common etiology was adhesion (39.6% of admissions), followed by small bowel volvulus (20.8%). Most patients (83.2%) underwent surgery during their admission. The most common diagnosis in patients who did not require surgery was also adhesion (68.0%), as well as for those who had surgery (33.9%), followed by small bowel volvulus (24.2%). CONCLUSIONS: The etiology of SBO in Ethiopia may be changing, with postoperative adhesions becoming more common than other historically more prevalent causes. Although a Gastrografin protocol as a diagnostic and potentially therapeutic aid for SBO is feasible in this population and setting, challenges can be anticipated, and future studies of protocol implementation and effectiveness are needed to further inform its utility in Ethiopia and other low-income and middle-income countries.

Small bowel diaphragm disease with multiple cluster lesions in one segment of the small bowel mimicking an adhesion band: A case report.

RATIONALE: Small bowel diaphragm disease (SBDD) is a rare case, caused by long-term administration of nonsteroidal anti-inflammatory drugs (NSAIDs). The circumferential diaphragm in the lumen of small bowel causing mechanical obstruction is the characteristic finding. PATIENT CONCERNS: A 74-year-old male was transferred to Pusan National University Yangsan Hospital (PNUYH) due to abdominal pain lasting for 2 months. He was treated in the local medical center (LMC) with Levin tube insertion and Nil Per Os (NPO) but showed no improvement. DIAGNOSIS: According to abdomen-pelvis computed tomography (CT) result, small bowel obstruction due to the adhesion band was identified, showing dilatation of the small bowel with abrupt narrowing of the ileum. INTERVENTIONS: Laparoscopic exploration was done but failed to find an adhesion band. An investigation of the whole small bowel was done with mini-laparotomy. At the transitional zone, the intraluminal air could not pass so the segmental resection of small bowel including the transitional zone and end-to-end anastomosis was done. OUTCOMES: After surgery, every laboratory finding recovered to the normal range in 4 days, but the patient's ileus lasted for 8 days. The patient's symptoms were relieved after defecation, he was discharged on postoperative day 10. LESSONS: For patients who show mechanical obstruction without an operation history but with long-term administration of NSAIDs, the clinicians should suspect small bowel diaphragm disease.

[Adhesions after abdominal surgery: developments in diagnosis and treatment]. / Adhesies na een buikoperatie.

Adhesions are a form of internal scar tissue, that develops in 70-90% of patients undergoing abdominal surgery. Although most adhesions are asymptomatic, adhesions cause a lifelong risk for complications, including adhesive small bowel obstruction (ASBO), chronic pain, infertility and difficulties during reoperations. ASBO is an abdominal emergency, resulting in hospital readmissions and a reoperation in 30-50% of cases. ASBO is associated with a high risk of recurrence. The risk of recurrence can be reduced by the use of adhesion barriers during operative treatment. Recent studies have demonstrated that elective adhesiolysis with use of adhesion barrier for pain is effective in selected patients. Novel imaging techniques, such as cineMRI, can help select patients in whom adhesiolysis is safe and effective. Reconstructive surgery with adhesiolysis is seldom performed for acquired infertility. However, this treatment has potential benefits over IVF in young couples.

Prediction of intraperitoneal adhesions in repeated cesarean sections: A Systematic review and Meta-analysis.

OBJECTIVE: With the rate of repeated cesarean sections on the rise, intraperitoneal adhesions caused by repeated cesareans could give rise to maternal morbidity during delivery. As a result, it's critical to have the ability to predict adhesions. The current meta-analysis aims to determine if intraperitoneal adhesions are likely to be present based on the characteristics of the cesarean scar, striae gravidarum, and sliding sign. MATERIALS AND METHODS: We systematically searched electronicdatabases beforeretrieving articles up until October 13th, 2022 for analysis. After data extraction and literature screening, we first performed a quality assessment using the QUADAS-2 score system. Following that, a bivariate random-effect meta-analysis model was used to obtain the combined diagnostic and predictive values. To pinpoint the origins of heterogeneity, we conducted a subgroup analysis. Fagan's Nomogram was used to validate the clinical utility. Sensitivity analysis was used to gauge the reliability of each included study, and Egger's test and funnel plot asymmetry was used to investigate publication bias. RESULTS: 25 studies totaling 1840 patients with intra-abdominal adhesions and 2501 controls without adhesions were included in the systematic review. Diagnostic values from 8 studies regarding skin characteristics were combined, and the results for depressed scar showed: sensitivity[95 %CI] = 0.38[0.34-0.42]; Specificity[95 %CI] = 0.88[0.85-0.90]; DOR[95 %CI] = 4.78[2.50-9.13]; AUC = 0.65. Negative sliding sign from 7 studies, although not showing a diagnostic difference between cases and controls, had excellent predictive values: sensitivity[95 %CI] = 0.71[0.65-0.77]; Specificity[95 %CI] = 0.87[0.85-0.89]; DOR[95 %CI] = 6.88[0.6-78.9]; AUC = 0.77. Subgroup analysis illustrated non-Turkish studies to reveal more significant associations than Turkish studies. CONCLUSION: Our meta-analysis found that the occurrence of adhesions can be predicted by the characteristics of abdominal wounds, particularly depressed scar, and scar width,as well as a negative sliding sign following a previous cesarean section.

Clinical Indicators to Determine the Timing of Surgery for Adhesive Small Bowel Obstruction.

BACKGROUND: Decompression of the intestine with a long tube or nasogastric tube is the first-choice treatment for adhesive small bowel obstruction (ASBO). Scheduling surgery while weighing the risks of surgery against conservative care is a crucial factor in clinical decision-making. Whenever feasible, unnecessary surgeries should be avoided, and it is essential to provide clinical markers for this. This study aimed to obtain evidence regarding the optimal timing of ASBO and when conservative treatment options are not successful. METHODS: The data of patients diagnosed with ASBO and receiving long tube insertion for more than 7 days were reviewed. We investigated transit ileal drainage volume and recurrence. The primary outcomes were the change in the drainage volume from the long tube over time and the percentage of patients who required surgery. We evaluated some cutoff values to determine the indication for surgery based on the insertion duration and volume of long tube drainage. RESULTS: Ninety-nine patients were enrolled in this study. Fifty-one patients showed improvement with conservative treatment, whereas 48 ultimately required surgery. When a daily drainage volume of ≥500 mL was considered an indication for surgery, 13-37 cases (25%-72%) would be judged unnecessary within 6 days of long tube insertion, while 5 cases (9.8%) would be judged unnecessary on day 7. DISCUSSION: Unnecessary surgical interventions for ASBO might be avoided by assessing the drainage volume on day 7 after inserting a long tube.

Adhesive Small Bowel Obstruction: A Review.

Adhesion is a leading cause of small bowel obstruction. Adhesive small bowel obstruction has significant challenges in diagnosis, treatment and prevention with considerable impact on morbidity and socioeconomic burden. Small bowel obstruction caused by adhesion or any other aetiology is clinically indistinguishable due to similar clinical presentation. Computed Tomography scans and water-soluble contrast studies are more specific in diagnosis and possess value in predicting the need for surgery. Surgical management is indicated only in complicated cases or failed conservative treatments with the majority resolving with non-operative management. However, there is no clear-cut consensus about the timing of operative intervention. Meticulous surgical practice is the keystone in preventing adhesion formation despite the availability of numerous pharmacological and surgical strategies. This review aims to update the current knowledge of the pathophysiology of adhesion formation, treatment options and various prevention modalities of adhesive small bowel obstruction. Keywords: diagnosis; laparotomy; prevention; surgery.

[Comparative analysis of clinical diagnosis application of two intrauterine adhesion scoring criteria].

Objective: To explore the similarities and differences of China Society of Gynecology Endoscopy (CSGE) and American Fertility Society (AFS) intrauterine adhesion (IUA) scoring criteria on IUA grading and their predictive value of reproductive prognosis. Methods: From January 2016 to January 2019, a total of 1 249 patients were diagnosed with IUA by hysteroscopy at Beijing Obstetrics and Gynecology Hospital. Totally, 378 patients with complete clinical data were enrolled, and the results diagnosed by CSGT and AFS scoring criteria were compared and analyzed.And follow-up for 2 years, the pregnancy rate and live birth rate were statistical analysis. Results: (1) The grade of IUA according to AFS and CSGE scoring criteria was less consistent (κ=0.295, P<0.001). Compared with AFS, the proportion of severe IUA cases diagnosed by CSGE was significantly lower [45.8% (173/378) vs 15.1% (57/378); RR=0.22, 95%CI: 0.15-0.30, P<0.01); the proportions of both mild and moderate IUA cases were significantly higher (RR=4.16, 95%CI: 2.38-7.14; RR=2.38, 95%CI: 1.75-3.23; both P<0.01). (2) The pregnancy rates of mild, moderate and severe IUA diagnosed according to CSGE were 11/13, 64.5% (147/228), 31.8% (7/22), live birth rates were 11/13, 54.8% (125/228) and 22.7% (5/22), respectively; there were statistically significant differences between the groups (all P<0.01). The pregnancy rates of mild, moderate and severe IUA diagnosed based on AFS were 3/3, 66.9% (97/145) and 56.5% (65/115), respectively, with no statistically significant difference between the groups (P>0.05). (3) IUA grades based on both CSGE and AFS criteria were significantly negatively correlated with pregnancy rates and live birth rates (CSGE: r=-0.210, r=-0.226; AFS: r=-0.130, r=-0.147; all P<0.05). Univariate logistic regression analysis showed that CSGE had higher OR for both pregnancy rates and live birth rates compared to AFS (3.889 vs 1.657, 3.983 vs 1.554, respectrvely). Conclusions: Compared with AFS, the IUA grade based on CSGE is better related with reproductive prognosis, suggesting that the CSGE standard might be more objective and comprehensive and has better predictive value for reproductive prognosis, thus avoiding overdiagnosis and overtreatment.

Labial synechiae: a diagnostic conundrum.

The purpose of this study was to shed some light on labial synechiae, which is a common yet unfamiliar condition seen initially by the family physician and ultimately by the paediatric urologist. It is often diagnosed incorrectly, leading to undue anxiety and stress for the unsuspecting parents, and results in multiple unnecessary lab investigations, hence, putting a burden on the healthcare system in general. After IRB approval, a retrospective chart review was performed over a period of 15 years (2007-2021), at The Indus Hospital, Karachi, Pakistan. The records of all female children who underwent examination under anaesthesia (EUA) for labial synechiae (n=29) were included in the study. Our results indicate that the primary healthcare physicians were unable to recognise labial adhesions at the time of initial presentation. We conclude that labial synechiae is a benign condition affecting female infants, but is not very well understood by healthcare workers in our part of the world.

Intrauterine adhesions combined with Robert's uterus: a case report and literature review.

PURPOSE: To summarize the clinical characteristics and surgical option of Robert's uterus. METHODS: We reported a rare case of Robert's uterus with severe uterine adhesion with successive laparoscopic and hysteroscopic surgery. To our knowledge, such a case has not been reported previously. We also performed a systematic literature review from the PubMed, Embase, and Cochrane databases. RESULTS: Our patient with Robert's uterus with severe uterine adhesions was successfully treated with hysteroscopic septal resection and hysteroscopic adhesiolysis, and the intractable dysmenorrhea disappeared after the hysteroscopic septal resection. In our study, we analyzed the selected 22 reported cases, 10/22 cases (45.5%) were diagnosed before age 20; 20/22 cases (90.91%) experienced dysmenorrhea, 19/22 cases (86.36%) were with hematometra. 5/22 cases (22.73%) underwent re-operation or a third surgery before diagnosis and management. CONCLUSION: Robert's uterus, a rare congenital abnormality of Mullerian duct development, consists of an oblique septum and non-communicating asymmetrical uterine hemi-cavity. The main symptoms are the presence of hematometra and severe dysmenorrhea. Septal resection is the main surgical procedure; however, the rarity and difficulty obtaining a pre-operative diagnosis lead to a high rate of misdiagnosis and second surgery.

An apparently healthy female crossbred Labrador retriever-poodle dog with severe intra-abdominal adhesions as an incidental finding to ovariohysterectomy.

An apparently healthy 1-year-old, female crossbred Labrador retriever-poodle dog was brought to a veterinary clinic for elective ovariohysterectomy (OVH). Severe abdominal adhesions complicated the procedure. There was no report of a previous illness or surgical procedure that would be a predisposing cause for the adhesions. The OVH was completed despite the adhesions and the dog recovered well. It is unclear whether this was simply a case of severe intra-abdominal adhesions or an atypical sclerosing encapsulating peritonitis (SEP). The differential diagnoses include inflammatory processes, a genetic predisposition, or an idiopathic cause. Fourteen days later, at the time of surgical staple removal, the dog was healthy and had reportedly been doing very well. Although rare, intra-abdominal adhesions can occur in young and previously healthy dogs without causing clinical signs. Veterinarians should be aware of such a condition when approaching abdominal surgeries and be prepared to manage these cases appropriately.

Une chienne Labrador retriever-caniche croisée apparemment en bonne santé avec d'importantes adhérences intra-abdominales comme découverte fortuite lors d'une ovariohystérectomie. Une chienne Labrador retriever-caniche croisée de 1an apparemment en bonne santé a été amenée dans une clinique vétérinaire pour une ovariohystérectomie élective (OVH). Des adhérences abdominales importantes ont compliqué la procédure. Il n'y avait aucun rapport d'une maladie ou d'une intervention chirurgicale antérieure qui serait une cause prédisposant aux adhérences. L'OVH a été complétée malgré les adhérences et la chienne a bien récupéré. Il n'est pas clair s'il s'agissait simplement d'un cas d'adhérences intra-abdominales importantes ou d'une péritonite sclérosante encapsulante (SEP) atypique. Les diagnostics différentiels incluent des processus inflammatoires, une prédisposition génétique ou une cause idiopathique. Quatorze jours plus tard, au moment du retrait des agrafes chirurgicales, la chienne était en bonne santé et se portait très bien. Bien que rares, des adhérences intra-abdominales peuvent survenir chez des jeunes chiens en bonne santé sans provoquer de signes cliniques. Les vétérinaires doivent être conscients d'une telle condition lorsqu'ils abordent des chirurgies abdominales et être prêts à gérer ces cas de manière appropriée.(Traduit par Dr Serge Messier).

CHARACTERISTICS AND MANAGEMENT OF MYOPIC TRACTION MACULOPATHY IN MYOPIC EYES WITH AXIAL LENGTH LESS THAN 26.5 mm.

PURPOSE: To explore the characteristics and underlying mechanisms of myopic traction maculopathy (MTM) with axial length less than 26.5 mm and to assess the effectiveness of macular buckling for the treatment of MTM. METHODS: Thirty-eight MTM eyes with axial length less than 26.5 mm were prospectively enrolled. Thirty-one eyes received surgery, and they were followed up for at least 6 months. Characteristics of MTM and surgical outcomes were evaluated. RESULTS: Of the MTM eyes, 92.11% (35/38) showed posterior staphyloma. Narrow macular staphyloma was the most common type (54.29%, 19/35), followed by peripapillary (37.14%, 13/35). Three cases (8.57%) had wide macular staphyloma, and 44.74% of cases (17/38) had vitreoretinal traction. Twenty-two MTM eyes of type T3 underwent macular buckling surgery, and all the cases achieved foveal reattachment after the surgery. The mean best-corrected visual acuity improved significantly at the 6-month follow-up (P < 0.001). Nine MTM eyes of type T4 or T5 received combined surgery, all macular holes recovered, and the best-corrected visual acuity also improved postoperatively (P = 0.008) as of the 6-month visit. CONCLUSION: Posterior staphyloma might serve as the initial force of the pathogenesis of MTM in eyes with axial length ˂26.5 mm. Macular buckling is a productive way to improve the MTM.

Effect of an anti-adhesion agent on vision-based assessment of cervical adhesions after thyroid surgery: randomized, placebo-controlled trial.

Many patients experience cervical adhesions after thyroid surgery. To date, however, no studies have objectively measured the effects of anti-adhesion agents on cervical adhesion symptoms. This study evaluated the effects of an anti-adhesion agent on cervical adhesions after thyroid surgery, as determined using a system that measures the extent of marker movement objectively. One hundred patients were randomized in a 1:1 ratio to undergo thyroid surgery with or without the anti-adhesion agent Collabarrier. Using specially manufactured recording equipment, the position of the marker on neck skin was measured before surgery, and 2 weeks, 3 months, and 9 months after surgery. Relative change in marker distance, calculated by subtracting the marker position before surgery from the marker positions 2 weeks, 3 months, and 9 months after surgery, differed significantly in the groups of patients who underwent thyroid surgery with and without the anti-adhesion agent (P < 0.05). A novel measuring system can objectively evaluate the effectiveness of a thyroid anti-adhesion agent. The anti-adhesion agent used significantly reduced adhesions compared with the control group. The trial is registered at www.cris.nih.go.kr (KCT0005745; date of registration, 08/01/2021).

Intrauterine Adhesions After Chlamydia Infection With a Levonorgestrel-Releasing Intrauterine Device in Place.

BACKGROUND: Little is known about the long-term reproductive effects of pelvic infection when a levonorgestrel-releasing intrauterine device (LNG-IUD) is in situ. Society guidelines do not recommend removing an LNG-IUD during pelvic infection. CASE: A 37-year-old woman presented with primary infertility, and the only contributing factor was intrauterine adhesions in the shape of an IUD. She was known to previously have an LNG-IUD and was treated for asymptomatic chlamydia infection while the IUD was in place. After lysis of adhesions, she successfully conceived spontaneously. CONCLUSION: Data on long-term reproductive effects of pelvic infection with an LNG-IUD in situ are not available, and there may be consequences affecting the intrauterine milieu requiring further studies and potential counseling.

Evaluation of the Diagnostic Accuracy of the Interview and Physical Examination in the Diagnosis of Endometriosis as the Cause of Chronic Pelvic Pain.

BACKGROUND: Chronic pelvic pain affects approximately 15% of reproductive age women. It is mainly caused by adhesions (20-40%). Despite CPP being the main symptom of endometriosis, the disease is confirmed by laparoscopy only in 12-18% of cases. The aim of this study was to evaluate the results of laparoscopy in women with CCP and to assess the sensitivity and specificity of elements of an interview and clinical examination. MATERIALS AND METHODS: The study included 148 women with CPP. Each patient underwent laparoscopy. In laparoscopy, the presence of endometriosis and/or peritoneal adhesions was confirmed. Then, the sensitivity and specificity and the positive and negative predictive value of endometriosis symptoms or abnormalities in the gynecological examination were statistically calculated. RESULTS: After previous surgery, adhesions were found in almost half (47%) of patients. In patients without a history of surgery, adhesions were diagnosed in 6.34% of patients. Endometriosis without coexisting adhesions was more often diagnosed in women without previous surgery (34.9%), compared to 10.58% in the group with a history of surgery (p < 0.05). CONCLUSIONS: Intraperitoneal adhesions are most common in women after pelvic surgery and with chronic ailments. The best results for sensitivity, specificity, positive predictive value, and negative predictive value in the diagnosis of endometriosis are found in women with irregular menstruations during which the pain increases. Laparoscopy still remains the primary diagnostic and therapeutic method for these women.

REVISED PREDICTIVE BIOMARKER FOR OCRIPLASMIN THERAPY IN VITREOMACULAR TRACTION DISORDERS.

PURPOSE: To determine a statistically optimal limit of adhesion size in vitreomacular traction (VMT) syndrome for ocriplasmin treatment. METHODS: In this retrospective, consecutive, interventional study, we included 106 patients treated with ocriplasmin injection because of VMT between July 2013 and January 2018. A univariate and multivariate risk analysis was performed with grouped factors and continuous factors. We used a receiver operating characteristic curve to measure the prognostic relevance of each continuous factor for therapy success and determined the statistically optimal cutoff value at which specificity and sensitivity are simultaneously maximized. RESULTS: Among the grouped factors, only a phakic lens status showed a highly significant positive influence on the resolution of the VMT. For the continuous factors, only the adhesion diameter before injection was a good predictor of anatomical success. The statistically optimal threshold value for the adhesion size was calculated to be 480 µm. Eyes below this limit had a 6.84-fold better chance of VMT resolution compared with eyes with a larger adhesion diameter. CONCLUSION: The threshold value of the VMT diameter for ocriplasmin therapy could be statistically defined as 480 µm and may thus be a new quantitative biomarker to predict treatment success.

Elevated peritoneal soluble endoglin and GDF-15 in infertile women with severe endometriosis and pelvic adhesion.

OBJECTIVES: Chronic inflammation and pelvic adhesion play a critical role in endometriosis-related infertility. Research studies suggest that TGF-ß superfamily members, such as soluble endoglin (sEng), growth differentiation factor 15 (GDF-15) and tumor growth factor-beta (TGF-ß1) contribute to the regulation of inflammation, angiogenesis and cell adhesion. The objective of this study is to investigate the association between the concentrations of these TGF-ß-related members and the clinical parameters of infertile women with endometriosis. MATERIALS AND METHODS: Sixty-five infertile women who underwent laparoscopy were divided into two groups in this study: those who had endometriosis (n = 33) and control subjects with benign gynecologic disorders (n = 32). The levels of TGF-ß- related members in peritoneal fluid and serum were evaluated by the enzyme-linked immunosorbent assay (ELISA). Clinical and hematological parameters were documented and analyzed. RESULTS: Endometriosis cases had significantly higher levels of sEng, GDF-15 and TGF-ß1 in peritoneal fluid (p<0.0005) compared to control subjects, but not in serum. Moreover, serum GDF-15 level was significantly elevated in the late-stage endometriosis compared to the early-stage group. The levels of three TGF-ß related molecules in peritoneal fluid showed positive correlations with rASRM score. Blood neutrophil counts have correlation with the peritoneal sEng concentration. CONCLUSION: Our novel evidence on the elevated concentration of peritoneal sEng and GDF-15 in endometriosis, specifically in the late-stage, may indicate the essential role of TGF-ß-dependent signaling in endometriosis. Serum GDF-15 might serve as a candidate biomarker for endometriosis severity. Further studies are warranted to investigate the role and regulation of these molecules in endometriosis.

Diagnostic yield and therapeutic outcome of hysteroscopy in women with infertility in a referral clinical setting: a Port Harcourt, Nigeria experience.

INTRODUCTION: intrauterine pathologies were traditionally evaluated by blind dilatation and curettage along with hysterosalpingography. Hysteroscopy is a veritable tool for evaluation of uterine cavity pathologies with an increasing availability in Nigeria. The study aims to report the diagnostic yield and therapeutic outcome of hysteroscopy in women with infertility from a Nigerian metropolis. METHODS: a retrospective cross-sectional study of consecutive cases of infertile women referred for hysteroscopy to an ambulatory care endoscopy facility in Port Harcourt, Nigeria. The variables collated included age, parity, past gynaecological history, indication, hysteroscopy findings and interventions. Statistical analysis was performed using SPSS version 25. RESULTS: included in study were 75 patients undergoing a total of 124 hysteroscopic procedures. The age range of patients was 25 to 56 years (mean 40.7 ± 5.9 years). A positive diagnostic yield of 93.3% with non-visualization of intracavitary uterine pathology in 5 patients was recorded. The most common pathologies were submucous myoma-25(31.3%), endometrial polyps- 18(22.5%) and intrauterine adhesions-18(22.5%). There was no statistical difference between the mean age of patients with or without polyp, myoma and intrauterine adhesions (P = 0.185, P = 0.510 and P = 0.619 respectively) but a non-linear relationship between age and polyp detection (Eta2 = 0.024). Operative hysteroscopies were all performed on out- patient basis but staged in 30(40.0%) patients. CONCLUSION: benign uterine growths and intrauterine adhesions are frequent causes of uterine factor infertility. A high successful completion rate of hysteroscopic interventions was achieved.

[Features of diagnosis and treatment of elderly and senile patients with adhesive small bowel obstruction.]

Adhesive small bowel obstruction is a common pathology with a tendency to increase characterized by a complex pathogenetic course with a high percentage of complications and deaths. Among the forms of intestinal obstruction caused by mechanical obstacles acute small bowel obstruction ranges from 64,3 to 80% with a mortality rate of 5,1 to 8,4% in the structure of urgent diseases. The complexity of early diagnosis along with an erased clinical picture severe course against a burdened background as well as age - in elderly and senile people leads to the search for new optimized treatment and diagnostic protocols. The purpose of this study was to study the nature of the course of adhesive small bowel obstruction in elderly and senile people to establish the information content of various diagnostic methods to determine the indications for the choice of the optimal period and method of treatment. A comparative analysis of 191 patients aged 60 to 90 years and older who received treatment in the surgical departments of St. Elizabeth Hospital (St. Petersburg) in the period from 2016-2019 was carried out. All patients were divided into 2 groups: the main group consisted of 106 patients (2018-2019) the comparison group included 85 patients (2016-2017). All patients of the main group used an improved diagnostic and treatment algorithm with the use of an original point-assessment scale which made it possible to optimize diagnostics and improve treatment results. Patients in the comparison group were examined in accordance with standard protocols and surgical treatment was carried out exclusively by traditional methods. The use of the proposed therapeutic and diagnostic algorithm made it possible to increase the probability of conservative resolution of acute adhesive small bowel obstruction from 20% (17) to 33% (35) and to reduce the incidence of postoperative complications from 60,2% (41) to 25,3% (18), p<0,01, and the mortality rate from 23,5% (16) to 7% (5), p<0,05.

Adhesive small bowel obstruction: Single band or matted adhesions? A predictive model based on computed tomography scan.

BACKGROUND: Preoperative identification of the cause of adhesive small bowel obstruction (ASBO) is crucial for decision making. Some computed tomography (CT) findings can be indicative of single adhesive bands or matted adhesions. Our aim was to build a predictive model based on CT data to discriminate ASBO due to single adhesive band or matted adhesions. METHODS: A retrospective single center study was conducted, covering all consecutive patients with a preoperative CT scan, undergoing urgent surgery for ASBO between January 1, 2005, and December 31, 2017. Preoperative CT scans were blindly reviewed, and all the CT findings indicative of single adhesive band or matted adhesions described in literature were recorded. According to intraoperative findings, ASBOs were retrospectively classified into single band and matted ASBO. All observed CT findings were compared between the two groups. A predictive model based on logistic regression was developed, and its ability was quantified by discrimination and calibration. Internal cross-validation was conducted by bootstrap resampling. RESULTS: A total of 116 patients were analyzed (males, 53.5%; median age, 68 years; single band ASBO in 65.5% of cases). The odds of single band ASBO were increased four times in presence of complete obstruction (odds ratios, 4.19; 95% confidence interval, 1.49-12.56) and seven times in presence of fat notch sign (odds ratios, 7.37; 95% confidence interval, 1.83-40.03). The predictive model combining all CT findings had an accuracy of 86% in single band ASBO prediction. Accuracy decreased to 79% in the internal validation. Sensitivity, specificity, and positive and negative predictive values were calculated at different cut-points of the predicted risk: using a 0.70 cut-point, the specificity is 80%, the sensitivity is 68%, and the positive and negative predictive values are 87% and 57%, respectively. CONCLUSION: The proposed predictive model based on combination of specific CT findings may elucidate whether ASBO is caused by single bands or matted adhesions and, consequently, influence the clinical pathway. LEVEL OF EVIDENCE: Prognostic study, level IV.

Paediatric adhesive bowel obstruction: a systematic review.

Adhesions following abdominal surgery remain a common cause of bowel obstruction. The incidence is between 1 and 12.6% in children who have had previous abdominal surgery. While conservative management is usually trialled in all patients (including children) suspected of having ASBO, the majority will require surgical intervention. New materials such as Seprafilm® have been studied in the paediatric population, with promising results of its use in index abdominal surgeries to prevent the formation of adhesions. In this article, we conducted a systematic review to present an overview of the current knowledge on the incidence, aetiology, pathophysiology, clinical presentation, and management of ASBO.
