Abstract
AIM Reporting of participant descriptors in studies of adhesive small bowel obstruction (ASBO) can help identify characteristics associated with favourable outcomes and allow comparison with other studies and real-world clinical populations. The aim was to identify the pattern of participant descriptors reported in studies assessing interventions for ASBO. METHOD This systematic review was registered with PROSPERO (CRD42021281031) and reported in line with the PRISMA checklist. Systematic searches of Ovid MEDLINE, Embase, and Cochrane Central Register of Controlled Trials (CENTRAL) were undertaken to identify studies assessing operative and non-operative interventions for adults with ASBO. Studies were dual screened for inclusion. Descriptors were categorised into conceptual domains by the research team. RESULTS Searches identified 2648 studies, of which 73 were included. A total of 156 unique descriptors were identified. On average, studies reported 12 descriptors. The most frequently reported descriptors were sex, age, SBO aetiology, history of abdominal surgery, BMI and ASA classification. The highest number of descriptors in a single study was 34, compared to the lowest number of descriptors which was one. Pathway factors were the least frequently described domain. Overall, 37 descriptors were reported in just one study. CONCLUSION There is a lack of consistency in participant descriptors reported in studies of SBO. Furthermore, a significant proportion of the descriptors were used infrequently. This makes it challenging to assess whether study participants are representative of the wider population. Further work is required to develop a Core Descriptor Set to standardise the reporting of patient characteristics and reduce heterogeneity between studies.

Abstract
BACKGROUND This comparative effectiveness study examined outcomes of operative vs. non-operative management for emergency general surgery (EGS) conditions in patients with recent cancer treatment (RT). METHODS Medicare beneficiaries with a history of colorectal cancer hospitalized for an EGS condition (2016-2018) were identified. RT was defined as chemotherapy/radiation within 3 months prior to admission. Instrumental variable analysis assessed the impact of management on mortality and readmissions among survivors (30d, 60d, and 90d), for patients in whom there was clinical equipoise regarding optimal management strategy. RESULTS Of 26,097 patients, 13% had undergone RT. In both the RT and non-RT groups, the optimal management strategy was uncertain in 14%. Operative management conferred increased risk of mortality but not readmission in patients with RT compared to those without (90d mortality:+43%, p = 0.03; 90d readmission:+7.1%, p = 0.776). CONCLUSIONS In patients with RT for whom there is clinical equipoise regarding EGS management, operative intervention increases risk of mortality.

Abstract
Background Limited evidence is available regarding the management of small bowel obstruction in the virgin abdomen (SBO-VA), with most studies excluding this entity. This study aims to assess the available data on the treatment outcomes and predictors of surgical intervention in SBO-VA. Methods A retrospective cross-sectional study was conducted between 2015 and 2021, including all diagnosed and managed cases of SBO-VA at Al-Nasar Hospital. Patients were divided according to the treatment approach into surgical or conservative groups. Preoperative laboratory and radiologic data were gathered and compared between groups. Results During the study period, 67 cases, primarily males (58.2%), with an average age of 52.2±14.4 years were assessed. Common comorbidities included diabetes (20.9%) and hypertension (16.4%). Key symptoms were rebound tenderness (82.1%) and abdominal tenderness (70.1%). The predominant etiology was adhesions (23.9%). About 46.2% received conservative treatment, 53.8% underwent urgent surgery. Conservative treatment failed in 9.4% of cases, and complications arose in 23.9%, with most being fever (17.9%). Factors necessitating surgical management included older age (58.8 ±11.7 vs 44.9 ±13.8 years, p<0.001), previous hospital admission (p<0.001), presence of abdominal tenderness (p=0.030), longer abdominal pain duration (4.0 ±0.9 vs 2.1 ±0.6 days, p<0.001), higher C- reactive protein (p= 0.033), higher white blood cell (p= 0.006), longer time to hospital presentation (75.3 ±17.2 vs 39.0 ±22.8 days, p= <0.001), small bowel thickness ≥3 cm (p=0.009), and reduced bowel enhancement (p <0.001) on computed tomography imaging. In surgical group, the need for ICU admission was higher and hospital stays were shorter than in conservative group and were statistically significant (p<0.05). Conclusion The main etiology of SBO-VA in our study was adhesions. Older age, previous hospital admission, longer abdominal pain duration, abdominal tenderness, increased inflammatory markers, and alarm signs on CT scans are the main factors for determining the need for urgent surgical exploration in patients with SBO-VA. To achieve prompt identification and intervention, it is crucial to maintain a high level of vigilance and awareness, even in individuals with no prior surgical history.

Abstract
Background: Small bowel obstruction (SBO) is a common disorder managed by surgeons. Despite extensive publications and management guidelines, there is no universally accepted approach to its diagnosis and management. We conducted a survey of acute care surgeons to elucidate their SBO practice patterns.Methods: A self-report survey of SBO diagnosis and management practices was designed and distributed by email to AAST surgeons who cared for adult SBO patients. Responses were analyzed with descriptive statistics and Chi-square test of independence at α = .05.Results: There were 201 useable surveys: 53% ≥ 50 years, 77% male, 77% at level I trauma centers. Only 35.8% reported formal hospital SBO management guidelines. Computed tomography (CT) scan was the only diagnostic exam listed as "essential" by the majority of respondents (82.6%). Following NG decompression, 153 (76.1%) would "always/frequently" administer a water-soluble contrast challenge (GC). There were notable age differences in approach. Compared to those ≥50 years, younger surgeons were less likely to deem plain abdominal films as "essential" (16.0% vs 40.2%; P < .01) but more likely to require CT scan (88.3% vs 77.6%; P = .045) for diagnosis and to "always/frequently" administer GC (84.0% vs 69.2%; P < .01). Younger surgeons used laparoscopy "frequently" more often than older surgeons (34.0% vs 21.5%, P = .05).Discussion: There is significant variation in diagnosis and management of SBO among respondents in this convenience sample, despite existing PMGs. Novel age differences in responses were observed, which prompts further evaluation. Additional research is needed to determine whether variation in practice patterns is widespread and affects outcomes.

Abstract
Introducción. La obstrucción intestinal es una patología de alta prevalencia. Su abordaje diagnóstico y terapéutico ha evolucionado acorde con el avance del conocimiento e implementación de la tecnología. El impacto de sus complicaciones obliga a redoblar esfuerzos en pro de lograr una mayor efectividad. Se hizo una aproximación reflexiva al problema, mediante una identificación de los puntos controversiales de interés para el cirujano general.
Métodos. Se realizó una búsqueda sistemática de la literatura en varias bases de datos, utilizando dos ecuaciones de búsqueda que emplearon términos seleccionados a partir de los tesauros “Medical Subject Heading” (MeSH) y “Descriptores en Ciencias de la Salud” (DeCS).
Resultados. Se recolectaron 43 artículos y a partir de ellos se construyó el texto de revisión. La identificación pronta de los posibles candidatos a cirugía, mediante un esquema diagnóstico y terapéutico, se constituye en una prioridad en el manejo de estos pacientes. De igual manera, se efectúan consideraciones en la toma de decisiones con respecto a la vía quirúrgica, así como recomendaciones técnicas operatorias producto de la experiencia y lo reportado en la literatura. Existen factores propios del cirujano, del contexto y del paciente, que inciden en la resolución del problema.
Conclusión. La obstrucción intestinal y sus implicaciones clínicas obligan a una reevaluación constante de su estado del arte y avances en el manejo, tendiente a una búsqueda de oportunidades para impactar favorablemente en su curso clínico. Hay estrategias por implementar, inclusive el manejo laparoscópico en casos seleccionados.

Abstract
OBJECTIVE To analyze the factors of mortality in patients with acute adhesive small bowel obstruction (AASBO). MATERIAL AND METHODS A retrospective multiple-center study included 143 (85.6%) patients with AASBO out of 167 consecutive patients with small bowel obstruction for the period 2017-2019. All patients were divided into 3 groups: early surgery group (within 12 hours after admission), late surgery (after 12 hours), non-surgical management group. The outcomes and Kaplan-Meier survival were compared in all groups. RESULTS AASBO was resolved without surgery in 77 (53.8%) patients 19.6±17.4 (M=14) hours. In the Early Surgery Group (n=36), 24 patients had strangulation, 12 ones had non-strangulated bowel obstruction. In the Late Surgery Group (n=30), 15 patients had strangulation and 15 ones had no strangulation. Mortality was similar in early and late surgery (p=0.287), early and late surgery in patients with strangulation (p=0.940), early and late surgery in patients without strangulation (p=0.76). Patients died (n=10) after surgery only. Thus, postoperative mortality was 15.2%, overall mortality - 7.0%. All patients who underwent surgery after 24 hours (n=14) survived. Surgery increased the mortality risk compared to non-surgical management (95% CI 0 - 15.9, p=0.001). There was no effect of surgery time (more or less than 12 hours) on mortality for strangulation (95% CI 13.0-16.7, p 0.788) and non-strangulated obstruction (95% CI 29.4-5.4, p=0.061), bowel resection (95% CI 33.3-14.0, p=0.187), presence of bowel ischemia (95% CI 14.3-17.9, p 0.613). CONCLUSION Delayed surgery may be advisable in patients with AASBO and no obvious signs of strangulation due to less mortality.

Abstract
BACKGROUND Gastrografin challenge is increasingly used as a diagnostic tool to predict patients who may benefit from nonoperative management in adhesive small bowel obstruction. This study explores the optimal timing of Gastrografin in the management of adhesive small bowel obstruction by comparing early versus late Gastrografin challenge. METHODS A retrospective chart review from January 2016 to January 2018 identified patients with adhesive small bowel obstruction who underwent Gastrografin challenge. A receiver operating characteristic curve, to predict a duration of stay less than 5 days, calculated a 12-hour limit which separated early and late groups. Nonoperative and operative patients were compared separately. Our primary outcome was duration of stay. Secondary outcomes included operative requirement, time to the operating room, complication rate, and 1-year mortality. In a separate analysis, multivariable logistic regression identified independent risk factors for 1-year mortality. RESULTS One hundred thirty-four patients were identified (58 early, 76 late). In nonoperative patients, the early group had a shorter duration of stay (3.2 days vs 5.4 days), fewer complications, and a lower complication and 1-year mortality rate (P < .05). In operative patients, the early group had a shorter preoperative duration of stay (1.8 days vs 3.9 days) (P < .05). On multivariable regression, congestive heart failure, any postoperative complication, and operative requirement were the best predictors of 1-year mortality (R2 = 0.321; P < .05). CONCLUSION Gastrografin administration within 12 hours of adhesive small bowel obstruction diagnosis had favorable outcomes in terms of duration of stay, complications, and mortality in nonoperative patients. Moreover, in operative patients, preoperative duration of stay was shortened. Our findings suggest protocolizing early Gastrografin challenge may be an important principle in adhesive small bowel obstruction management.

Abstract
INTRODUCTION Laparoscopic adhesiolysis is increasingly being used to treat adhesional small bowel obstruction (ASBO) as it has been associated with reduced postoperative length of stay (LOS) and faster recovery. However, concerns regarding limited working space, iatrogenic bowel injury and failure to relieve the obstruction have limited its uptake. This study reports our centre's experience of adopting laparoscopy as the standard operative approach. METHODS A single-centre prospective cohort study was performed incorporating local data from the National Emergency Laparotomy Audit Database; January 2015 to December 2019. All patients undergoing surgery for ASBO were included. Patient demographic, operative and inhospital outcomes data were compared between different surgical approaches. Linear regression analysis was performed for LOS. RESULTS A total of 299 cases were identified. Overall, 76.3% of cases were started laparoscopically and 52.2% were completed successfully. Patients treated laparoscopically had lower Portsmouth - Physiological and Operative Severity Score for the enuMeration of Mortality and morbidity (P-POSSUM) predicted mortality (median 2.1 (interquartile range (IQR) 1.3-5.0) vs 5.7 (IQR 2.0-12.4), p=<0.001) and shorter postoperative LOS compared with open (median 4.2 days (IQR 2.5-8.2) vs 11.3 days (IQR 7.3-16.6), p=0.000). Inhospital mortality was lower in the laparoscopic group (2 vs 7 deaths, p=<0.001). In regression analysis, laparoscopic surgery was found to have the strongest association with postoperative LOS (β -8.51 (-13.87 to -3.16) p=0.002) compared with open surgery. CONCLUSIONS Laparoscopy is a safe and feasible approach for adhesiolysis in the majority of patients with ASBO. It is associated with reduced LOS with no impact on complications or mortality.

Abstract
BACKGROUND Small bowel obstruction (SBO) no longer mandates urgent surgical evaluation raising the question of the role of operating room (OR) access on SBO outcomes. METHODS Data from our 2015 survey on emergency general surgery (EGS) practices, including queries on OR availability and surgical staffing, were anonymously linked to adult SBO patient data from 17 Statewide Inpatient Databases (SIDs). Univariate and multivariable associations between OR access and timing of operation, complications, length of stay (LOS), and in-hospital mortality were measured. RESULTS Of 32,422 SBO patients, 83% were treated non-operatively. Operative patients were older (median 66 vs 65 years), had more comorbidities (53% vs 46% with ≥ 3), and experienced more systemic complications (36% vs 23%), higher mortality (2.8% vs 1.4%), and longer LOS (median 10 vs 4 days). Patients had lower odds of operation if treated at hospitals lacking processes to tier urgent cases (aOR 0.90, 95% CI [0.83-0.99]) and defer elective cases (aOR 0.87 [0.80-0.94]). Patients had higher odds of operation if treated at hospitals with surgeons sometimes (aOR 1.14 [1.04-1.26]) or rarely/never (aOR 1.16 [1.06-1.26]) covering EGS at more than one location compared to always. Odds of systemic complication (OR 2.0 [1.6-2.4]), operative complication (OR 1.5 [1.2-1.8]), and mortality were increased for very late versus early operation (OR 2.6 [1.7-4.0]). CONCLUSIONS Although few patients with SBO require emergency surgery, we identified EGS structures and processes that are important for providing timely and appropriate intervention for patients whose SBO remains unresolved and requires surgery.

Abstract
BACKGROUND AND AIMS Approximately 75% of patients admitted with small bowel obstruction have intra-abdominal adhesions as their cause (adhesive small bowel obstruction). Up to 70% of adhesive small bowel obstruction cases, in the absence of strangulation and bowel ischemia, can be successfully treated with conservative management. However, emerging evidence shows that surgery performed early during the first episode of adhesive small bowel obstruction is highly effective. The objective of this narrative review is to summarize the current evidence on adhesive small bowel obstruction management strategies. MATERIALS AND METHODS A review of the literature published over the last 20 years was performed to assess Who, hoW, Why, When, What, and Where diagnose and operate on patients with adhesive small bowel obstruction. RESULTS Adequate patient selection through physical examination and computed tomography is the key factor of the entire management strategy, as failure to detect patients with strangulated adhesive small bowel obstruction and bowel ischemia is associated with significant morbidity and mortality. The indication for surgical exploration is usually defined as a failure to pass contrast into the ascending colon within 8-24 h. However, operative management with early adhesiolysis, defined as operative intervention on either the calendar day of admission or the calendar day after admission, has recently shown to be associated with an overall long-term survival benefit compared to conservative management. Regarding the surgical technique, laparoscopy should be used only in selected patients with an anticipated single obstructing band, and there should be a low threshold for conversion to an open procedure in cases of high risk of bowel injuries. CONCLUSION Although most adhesive small bowel obstruction patients without suspicion of bowel strangulation or gangrene are currently managed nonoperatively, the long-term outcomes following this approach need to be analyzed in a more exhaustive way, as surgery performed early during the first episode of adhesive small bowel obstruction has shown to be highly effective, with a lower rate of recurrence.

Abstract
BACKGROUND Nonoperative management of adhesive small bowel obstruction (ASBO) results in resolution for the majority of patients. Previous studies have demonstrated that outcomes for patients with ASBO are improved when patients are admitted to a surgical service, but the effect of general surgery resident coverage is unclear. This study measures quality outcomes for patients with ASBO after the establishment of a new general surgery residency program. METHODS An institutional review board-approved retrospective chart review of admissions for ASBO was conducted following the implementation of a protocol for ASBO nested within a newly developed resident-run emergency general surgery (EGS) service. Patients successfully treated without operative intervention were analyzed. RESULTS During the study period, 612 patients were admitted for ASBO. After initiation of the residency, 74% of ASBO were admitted to a surgical service compared with 35% prior to residency (P < .01). Length of stay was reduced by 0.77 days (P = .016), average direct total cost per patient was reduced by 24% (P = .002), and 30-day readmissions were reduced by 35.7% (P = .046). There was no significant difference in mortality (1.4% vs 1.0%). DISCUSSION Admission to a resident-run surgical service was associated with statistically significant improvement in outcomes for patients with ASBO. These data corroborate prior studies demonstrating the positive impact of residency programs on patient outcomes and provide additional evidence that general surgery residency programs improve outcomes for patients with surgical disease.

Impact of Operative Management on Recurrence of Adhesive Small Bowel Obstruction: A Longitudinal Analysis of a Statewide Database. J Am Coll Surg 2020; 230:544-551.e1.

Abstract
BACKGROUND Recurrence of adhesive small bowel obstruction (ASBO) can lead to multiple admissions. There is limited knowledge of the role of operative and nonoperative treatment in the long-term recurrence risk for ASBO. We sought to determine the effect of operative and nonoperative management on future ASBO recurrences. METHODS This is a retrospective study of administrative discharge data from the Tennessee Hospital Association. Adult discharges from 2007 to 2009 with ASBO and all subsequent readmission within any hospital in the state were included; patients with earlier ASBO from 2003 to 2007 and out-of-state residents were excluded. ASBO recurrence was compared between operative and nonoperative approaches using the Andersen-Gill approach for modeling recurrent time-to-event data. Secondary outcomes included mortality, complication, and time to recurrence. RESULTS We analyzed 6,191 records; 30.0% were initially treated operatively. Patients initially managed surgically had lower overall recurrence rates (19.0% vs 25.6%; p < 0.005). The hazard for recurrence was lower if the most recent ASBO management was operative (hazard ratio 0.27; 95% CI, 0.23 to 0.31). The risk of ASBO recurrence increased with more cumulative operative or nonoperative ASBO admissions relative to patients with fewer earlier admissions (operative: hazard ratio 2.30; 95% CI, 2.04 to 2.60 and nonoperative: hazard ratio 1.18; 95% CI, 1.16 to 1.20). In-hospital mortality rate (3.7% vs 2.6%; p = 0.025) and time to recurrence (729 vs 550 days; p = 0.009) were greater in the operative group. CONCLUSIONS Operative management for the most recent ASBO is associated with fewer recurrences. Subsequent cumulative recurrences of ASBO predispose to recurrence regardless of operative or nonoperative management. When considering ASBO management, subsequent recurrence should be considered.
