Blunt abdominal trauma (BAT) is a major contributor to trauma-related morbidity and mortality worldwide, particularly among young adults involved in road traffic accidents, falls from height, and assaults. Solid abdominal organs such as the spleen, liver, kidneys, and pancreas are frequently affected because of their vascularity and anatomical location. Early diagnosis and prompt management are essential to prevent hemorrhage, organ failure, and death. Improvements in trauma systems, imaging techniques, and critical care have significantly enhanced survival rates in patients with blunt abdominal injuries.^[1]

Historically, exploratory laparotomy was considered the standard treatment for most blunt abdominal injuries because of concerns regarding missed intra-abdominal hemorrhage. However, increasing experience with focused assessment with sonography for trauma (FAST), contrast-enhanced computed tomography (CECT), and intensive monitoring has transformed the management of solid organ injuries. Current evidence supports selective non-operative management (NOM) in hemodynamically stable patients, allowing preservation of injured organs while avoiding unnecessary surgical intervention.^[2]

The spleen and liver are the most commonly injured organs following blunt abdominal trauma. Advances in trauma imaging have enabled accurate grading of these injuries, facilitating individualized treatment decisions. The World Society of Emergency Surgery (WSES) guidelines recommend that management should be determined primarily by the patient's hemodynamic status rather than injury grade alone, with non-operative treatment being the preferred strategy for stable patients and surgery reserved for persistent instability or associated injuries.^[3]

Similarly, management guidelines from the Eastern Association for the Surgery of Trauma (EAST) emphasize that most blunt hepatic injuries can be managed conservatively provided that the patient remains hemodynamically stable and appropriate imaging and monitoring facilities are available. This approach has reduced unnecessary laparotomies and improved organ preservation without compromising patient safety.^[4]

The success of non-operative management depends on careful patient selection, continuous clinical observation, serial abdominal examinations, and timely radiological assessment. Leppäniemi highlighted that modern trauma care has shifted from mandatory operative intervention to organ-preserving strategies supported by CT imaging and intensive monitoring, resulting in lower morbidity and shorter hospital stays.^[5]

Recent literature has consistently demonstrated excellent outcomes with conservative management in appropriately selected patients. Kanlerd et al. reported that non-operative management has become the standard treatment for most blunt solid organ injuries, with high success rates and low complication rates when combined with careful monitoring and prompt recognition of treatment failure.^[6]

Despite these advances, operative intervention remains indispensable in patients with hemodynamic instability, generalized peritonitis, active hemorrhage, or failure of conservative management. Comparing the outcomes of operative and non-operative treatment is therefore important for optimizing patient selection and improving trauma care protocols.[7,8] Accordingly, the present study was undertaken to compare conservative and operative management of blunt abdominal solid organ injuries with respect to treatment outcomes, complications, hospital stay, and mortality in patients managed at a tertiary care teaching hospital.

Study Design

The present study was designed as a prospective hospital-based observational comparative study comparing conservative and operative management of blunt abdominal solid organ injuries.

 Study Setting

The study was conducted in the Department of General Surgery at Basaveshwar Teaching and General Hospital, attached to M.R. Medical College, Kalaburagi, a tertiary care referral center.

 Study Duration

The study was carried out over 18 months, from December 2017 to June 2019.

 Study Population

The study included patients admitted with blunt abdominal trauma involving solid abdominal organs, namely the spleen, liver, kidneys, and pancreas.

 Sample Size

A total of 50 consecutive patients fulfilling the study criteria were enrolled.

 Inclusion Criteria

• Patients of any age and either sex with blunt abdominal trauma.
• Radiological or operative evidence of injury involving the spleen, liver, kidneys, or pancreas.
• Patients managed either conservatively or surgically.

 Exclusion Criteria

• Penetrating abdominal injuries.
• Pregnant women.
• Patients with associated head injuries or thoracic injuries.
• Patients with hollow viscus injuries without associated solid organ trauma.

Data Collection

After admission and initial resuscitation, demographic details, mechanism of injury, clinical presentation, laboratory investigations, imaging findings, treatment modality, operative procedures, complications, duration of hospital stay, and mortality were recorded using a predesigned proforma.

Diagnostic Evaluation

All patients underwent detailed clinical examination and FAST. Ultrasonography was performed in all patients, while contrast-enhanced CT scan was carried out in hemodynamically stable patients. Four-quadrant aspiration and diagnostic peritoneal lavage were performed when clinically indicated. Patients with persistent hemodynamic instability underwent immediate exploratory laparotomy.

Treatment Protocol

Conservative Management

Hemodynamically stable patients without generalized peritonitis were managed non-operatively with:

• Strict bed rest.
• Serial abdominal examinations.
• Hourly monitoring of pulse, blood pressure, and respiratory rate.
• Repeat ultrasonography whenever clinically indicated.
• Supportive medical management and blood transfusion as required.

 Operative Management

Patients with persistent hemodynamic instability, worsening clinical condition, or imaging findings suggestive of major intra-abdominal injury underwent emergency exploratory laparotomy. Surgical procedures included splenectomy, splenorrhaphy, hepatorrhaphy, and distal pancreatectomy depending on intraoperative findings.

 Outcome Measures

Primary outcomes included:

• Success of conservative versus operative management.
• Type of operative procedure.

Secondary outcomes included:

• Post-treatment complications.
• Duration of hospital stay.
• In-hospital mortality.

 Statistical Analysis

Data were entered into Microsoft Excel and analyzed using descriptive statistical methods. Categorical variables were expressed as frequencies and percentages, while continuous variables were summarized using mean values and ranges. Comparative outcomes between conservative and operative groups were assessed where appropriate, with a p-value <0.05 considered statistically significant.

 Ethical Considerations

The study was conducted after obtaining approval from the Institutional Ethics Committee. Written informed consent was obtained from all patients or their legally authorized representatives before enrollment. Patient confidentiality was maintained throughout the study.

A total of 50 patients with blunt abdominal solid organ injuries were included in the study. Based on hemodynamic status and imaging findings, 31 patients (62%) were managed conservatively, whereas 19 patients (38%) underwent operative intervention. Comparative analysis of demographic profile, injury characteristics, treatment outcomes, complications, hospital stay, and mortality was performed.

 Table 1. Baseline characteristics and treatment distribution among study participants (n=50)

Of the 50 patients, 82% were males and 18% were females, with no significant difference in gender distribution between treatment groups (p=0.894). The highest incidence occurred in the 21–30-year age group (44%), followed by the 31–40-year age group (30%). Road traffic accidents were the predominant mechanism of injury (58%), followed by falls from height (24%) and assault (18%). Baseline demographic characteristics and mechanism of injury were comparable between conservative and operative groups (p>0.05).

 Table 2. Comparison of Injury Characteristics, Management, and Operative Procedures Among Patients with Blunt Abdominal Solid Organ Injuries

The spleen was the most frequently injured solid organ (48%), followed by the liver (44%), kidney (16%), and pancreas (6%). Multiple organ injuries were observed in 12% of patients. Conservative management was successfully employed in 62% of patients, whereas 38% required operative intervention (p=0.119). Among surgically managed patients, splenectomy (42.1%) was the most commonly performed procedure, followed by hepatorrhaphy (26.3%), reflecting the predominance of splenic and hepatic injuries. There was no statistically significant difference in the distribution of pancreatic or multiple organ injuries between the treatment groups (p>0.05).

Table 3. Clinical outcomes according to treatment modality

 *Statistically significant.

Respiratory complications occurred more frequently in the operative group (31.6%) than in the conservative group (9.7%), although the difference was not statistically significant (p=0.067). Intra-abdominal abscess occurred with similar frequency in both groups (p=1.000). Wound infection (21.1%) and wound dehiscence (5.3%) were observed exclusively after surgery.

The mean duration of hospital stay was longer in the operative group (19 days) than in the conservative group (14 days), demonstrating a statistically significant difference (p=0.041). Overall mortality was 12%, with mortality being higher among operated patients (21.1%) than conservatively managed patients (6.5%), although this difference did not reach statistical significance (p=0.184).

Table 4. Overall Treatment Outcomes in Patients with Blunt Abdominal Solid Organ Injuries (n = 50)

*Statistically significant (p < 0.05).

Overall, 62% of patients were successfully managed conservatively, while 30% underwent successful operative management. The overall survival rate was 88%, with an overall mortality of 12%. Most patients (80%) were discharged within 20 days, and the mean duration of hospital stay was 16 days. The overall treatment outcome was statistically significant (p = 0.038), indicating favorable outcomes with appropriate selection of conservative and operative management based on the patient's clinical condition and hemodynamic status.

The present study compared conservative and operative management of blunt abdominal solid organ injuries and demonstrated that 62% of patients were successfully managed conservatively, while 38% required operative intervention because of hemodynamic instability or significant intra-abdominal injury. The spleen was the most commonly injured organ, and respiratory complications and mortality were more frequent among surgically treated patients, reflecting the greater severity of injury in this group.

The World Society of Emergency Surgery (WSES) liver trauma guidelines published by Coccolini et al. emphasized that the choice between operative and non-operative management should primarily depend on the patient's hemodynamic status rather than the anatomical grade of injury. They recommended non-operative management as the standard approach for stable patients with blunt liver injuries, reserving surgery for unstable patients or those with ongoing hemorrhage. The present study supports these recommendations, as nearly two-thirds of patients were successfully managed conservatively, while surgery was performed only in unstable patients.^[9]

Similarly, Karachentsev reported successful implementation of non-operative management for blunt solid organ injuries in a rural hospital, demonstrating that favorable outcomes can be achieved with careful patient selection and close clinical monitoring, even in resource-limited settings. Comparable findings were observed in the present study, where conservative management resulted in satisfactory outcomes with relatively low mortality among hemodynamically stable patients.^[10]

 Singh et al. evaluated blunt abdominal trauma in a Level I trauma centre and found that young males involved in road traffic accidents constituted the majority of patients, with splenic and hepatic injuries being the most common. They concluded that selective non-operative management provides excellent outcomes, whereas operative intervention remains essential for unstable patients. These observations closely parallel the present findings, where splenic injuries predominated and operative management was reserved for patients with hemodynamic instability or severe abdominal injury.^[11]

A comprehensive review by Kanlerd et al. further confirmed that non-operative management has become the preferred treatment for most blunt abdominal solid organ injuries owing to advances in imaging, intensive monitoring, and trauma care. The authors highlighted that successful conservative treatment depends on strict patient selection, serial clinical examination, and timely recognition of treatment failure. The present study demonstrated a similar management strategy, with 62% of patients successfully managed without surgery and only a minority requiring operative intervention.^[12]

More recently, Mukharjee et al. prospectively evaluated CT-confirmed blunt solid organ injuries and reported high success rates with conservative management in hemodynamically stable patients. They emphasized that contrast-enhanced CT accurately defines injury severity and facilitates appropriate treatment decisions. In the present study, CT scan played a key role in identifying splenic, hepatic, renal, and pancreatic injuries and assisted in selecting patients suitable for non-operative management.^[13]

 Quinn et al. reassessed the role of FAST and diagnostic peritoneal aspiration in unstable blunt abdominal trauma and concluded that rapid bedside assessment remains crucial for identifying patients requiring immediate laparotomy. They emphasized that imaging findings should always be interpreted alongside clinical status. The present study supports this approach, as hemodynamically unstable patients underwent emergency laparotomy based on clinical evaluation, FAST, and adjunctive investigations, whereas stable patients underwent CT-guided conservative management.^[14]

The findings of the present study demonstrate that selective non-operative management is safe and effective for the majority of hemodynamically stable patients with blunt abdominal solid organ injuries, while operative intervention remains lifesaving in unstable patients. Appropriate patient selection using clinical assessment and modern imaging modalities allows optimal treatment, minimizes unnecessary laparotomy, and contributes to favorable clinical outcomes.
