Outcomes for sigmoid volvulus managed with and without early definitive surgery: 20-year experience in a tertiary referral centre.

BACKGROUND: Sigmoid volvulus is rare in Western countries. Patients at risk of sigmoid volvulus are often older with significant co-morbidity. Without sigmoid colectomy there is a high recurrence rate, but indications for surgery are controversial. METHODS: A retrospective observational study was conducted by reviewing clinical records of patients admitted to Waikato Hospital 1 January 2000 to 1 January 2020 with a diagnosis of sigmoid volvulus. Patient characteristics, clinical features, investigations, management, and outcomes were recorded. RESULTS: One hundred and thirty-two patients (87 male) were included with 203 volvulus episodes. Median age 76 years, median Charlson co-morbidity index (CCI) 4. Median follow-up 11 years. 44/132 (33.3%) had surgery during the index admission, two had elective surgery and the remainder had planned non-operative management. 73/132 (55.3%) had surgery at any stage. 42/86 (48.8%) patients managed non-operatively recurred; 66.7% of recurrences were within 6 months. Forty-three (32.6%) died within 12 months of index admission; 28 (21.2%) died during an admission for volvulus. On univariate analysis higher age and abnormal vital signs were associated with inpatient and 12-month mortality; higher CCI was associated with 12-month mortality. On multi-variate analysis increasing age in years was associated with increased risk of death (HR 1.089 [1.052-1.128, P < 0.001]). Normal vital signs at presentation were associated with decreased risk of death (HR 0.147 [0.065-0.334, P < 0.001]). CONCLUSION: Sigmoid colectomy should be considered at index presentation with sigmoid volvulus. Half of patients managed non-operatively recurred, with two-thirds recurring within 6 months. The mortality rate remains high for subsequent volvulus episodes.

Management of thoracoabdominal gunshot wounds - Experience from a major trauma centre in South Africa.

INTRODUCTION: The management of thoracoabdominal (TA) gunshot wounds (GSW) remains challenging. This study reviewed our experience with treating such injuries over a decade. MATERIALS AND METHODS: A retrospective study was conducted at a major trauma centre in South Africa over a ten-year period from December 2012 to January 2022. RESULTS: Two hundred sixteen cases were included (male: 85 %, mean age: 33 years). Median RTS: 8 and median ISS: 17 (IQR: 10-19). The mean value of physiological parameters: Heart Rate (HR): 98/min, Systolic Blood Pressure (SBP): 119 mmHg, Temperature (T): 36.2 °C, pH: 7.35, Lactate 3.7 mmol/l. Ninety-nine (46 %) underwent a CT scan of the torso. One hundred fifty-four cases (69 %) were managed operatively: thoracotomy only [5/154 (3 %)], laparotomy only [143/154 (93 %)], and combined thoracotomy and laparotomy [6/154 (4 %)]. Those who had surgery following preoperative CT had a lower rate of dual cavity exploration (2 % vs 4 %, p = 0.51), although it did not reach statistical significance. The overall morbidity was 30 % (69). 82 % required intensive care (ICU) admission. The mean length of hospital stay was 14 days. The overall mortality was 13 % (28). Over the 10-year study period, there was a steady increase in the number of cases of TA GSWs managed at our institution. Over the study period, an increasing use of CT was noted, along with a steady reduction in the proportion of operations performed. CONCLUSIONS: Thoraco-abdominal GSWs remain challenging to manage and continue to be associated with significant morbidity and mortality. The increased use of CT scans has reduced the degree of clinical confusion around which body cavity to prioritize, leading to an apparent decrease in dual cavity exploration, and has allowed for the increased use of minimalistic and non-operative approaches.

Double Jeopardy Injuries: Improved Clinical Outcomes With FAST Imaging and Subxiphoid Pericardial Window for Combined Cardiac and Abdominal Stab Wounds.

BACKGROUND: This study reviews our experience with combined cardiac and abdominal stab wounds over 12 years and reviews how changes in technology and clinical approaches have impacted our management of these patients. MATERIALS AND METHODS: A retrospective cohort study was conducted from January 2008 to January 2020 at a major trauma centre in South Africa. All patients with concurrent SWs to the chest and the abdomen and required both a thoracotomy for cardiac injury and a laparotomy for an intra-abdominal injury at the same setting were included. RESULTS: Twenty-two cases were identified (100% male, mean age: 27 years). Mean values of admission physiology: systolic blood pressure (SBP): 85 mmHg, pH: 7.2, base excess: -10.2 mmol/L and serum lactate 6.7 mmol/L. Thirty-two percent (7/22) of cases underwent a Focused Assessment with Sonography in Trauma (FAST) scan (5 positive and 2 negative). All 7 cases had intraoperatively confirmed cardiac injuries. The thoracotomy first approach was used in 18 cases (82%), and the laparotomy first approach was used in the remaining 4 cases (18%). Nineteen (86%) of the 22 laparotomies were positive. A total of 6 patients (27%) experienced one or more complications. The mean length of hospital stay was 9 days. The overall mortality was 18% (4/22) and all mortality occurred prior to 2013. DISCUSSION: Double jeopardy is still associated with an increased risk of mortality. The use of FAST and Subxiphoid Pericardial Windows (SPWs) have reduced clinical uncertainty, decreasing the need for concomitant thoracotomy and laparotomy to be performed.

Penetrating buttock trauma is morbid but rarely fatal - A South African experience.

BACKGROUND: Penetrating injuries to the buttock are relatively rare but are associated with significant morbidity. This study aimed to review our experience in managing penetrating trauma to the buttocks to contextualize the injury, document the most common associated injuries, and generate an algorithm to assist with the management of these patients. METHODS: A retrospective study was conducted at a major trauma center in South Africa over 8 years (January 2012 to January 2020). All patients presenting with a penetrating buttock injury were included. RESULTS: Our study included 40 patients. Gunshot wounds accounted for 93% (37/40), stab wounds accounted for 5% (2/40), and 1 case was gored by a cow. The majority (98%) underwent further investigation in the form of imaging or endoscopy. Forty percent (16/40) required surgical intervention. Of these 16 cases, 14 required a laparotomy, and 2 required gluteal exploration. Fifty-six percent (9/16) required a stoma. Five percent (2/40) experienced one or more complications, both of whom had stomas. The median length of stay for all patients was 3 days, whereas for the patients with stomas was 7 days. There were no ICU admissions or mortality in this study. Only 3 of the 9 stomas were reversed, and the median time to reversal was 16 months. CONCLUSION: Penetrating trauma to the buttock may result in injuries to surrounding vital structures, which must be actively excluded. Rectal injury was the most common injury, and most required a defunctioning colostomy as part of the management resulting in significant morbidity.

Contemporary management of isolated free fluid on computed tomography scan in blunt abdominal trauma-experience from a Level 1 trauma centre in New Zealand.

AIMS: The management of patients with blunt abdominal trauma (BAT) who have isolated free fluid (IFF) with no solid organ injury (SOI) on computed tomography (CT) remains controversial. This study aims to determine if the volume of free fluid (FF) is a predictor of the need for operative management of traumatic intra-abdominal injuries, by reviewing the local cumulative experience with IFF at a major trauma centre in New Zealand. METHODS: A retrospective study was undertaken over nine years at a Level 1 trauma centre in New Zealand. Patients aged over 15 years who sustained BAT and had IFF with no SOI demonstrated on CT were included. All CT scans and patient notes were reviewed. The volume of free fluid was classified by the local interpreting radiologist on the CT report. RESULTS: Eighty-two out of 1,177 BAT patients (7%) had IFF with no SOI on CT. Thirty-eight percent were males, with a median age of 31 years. Nineteen (23%) underwent immediate operative management (OM) at the time of presentation. The remaining 63 patients had a trial of non-operative management (NOM), 10 (16%) of which were unsuccessful and required an operation. Overall, 29 patients (35%) required operative management. Eighty-nine percent of the OM group and 90% who failed NOM had positive operative findings, giving an overall true positive of 32%. CONCLUSIONS: The presence of IFF in itself is not an absolute indication for operative exploration and many patients with trace IFF can be managed non-operatively. Small amounts of IFF should be regarded with suspicion, and moderate or large amounts of fluid are likely to require operative exploration. Further work must make use of clinical scoring systems and laparoscopy or laparotomy to assess patients at high risk of surgically remediable intra-abdominal injury post BAT.

Foley Catheter Balloon Tamponade for Actively Bleeding Wounds Following Penetrating Neck Injury is an Effective Technique for Controlling Non-Compressible Junctional External Haemorrhage.

BACKGROUND: The foley catheter balloon tamponade (FCBT) has been widely employed in the management of trauma. This study reviews our cumulative experience with the use of FCBT in the management of patients presenting with a penetrating neck injury (PNI). METHODS: A retrospective study was conducted at a major trauma centre in South Africa over a 9-year period from January 2012 to December 2020. All patients who presented with a PNI who had FCBT were included. RESULTS: A total of 1581 patients with a PNI were managed by our trauma centre, and 44 (3%) patients had an FCBT. Of the 44 cases of FCBT, stab wounds accounted for 93% (41/44) and the remaining 7% were for gunshot wounds. Seventy-five per cent of all FCBT (33/44) were inserted at a rural hospital prior to transfer to our trauma centre; the remaining 25% (11/44) were inserted in our resuscitation room. The success rate of FCBT was 80% (35/44), allowing further CT with angiography (CTA) to be performed. CTA findings were: 10/35 (29%) positive, 18/35 (51%) negative, and 7/35 (20%) equivocal. Fifteen patients required additional intervention (open surgery or endovascular intervention). The overall morbidity was 14% (6/44). Eighteen per cent required intensive care unit admission. The median length of stay was 1 day. The overall mortality rate was 11% (5/44). CONCLUSION: FCBT is a simple and effective technique as an adjunct in the management of major haemorrhage from a PNI. In highly selective patients, it may also be used as definitive management.
