Should cholangiography be part of the management of every patient with percutaneous cholecystostomy?

INTRODUCTION: Percutaneous cholecystostomy (PCC) is a well-established treatment in patients with high surgical risk and those who failed conservative treatment. However, the role of cholangiography in the management of PCC patients is not clear. In our medical center, cholangiography is routinely performed before discharging patient with PCC. We aimed to evaluate the utility of this test and its effect on the patient's management. METHODS: The study included all patients managed with PCC between 2015 to 2017. The patients were divided to those with positive findings and those with no findings. The two groups were compered in demographical and clinical parameters. RESULTS: 119 patients underwent PCC during the study period. Indication for PCC were comorbidities in 73% and failure of conservative treatment in 27%. Cholangiography was performed in 95 patients. Third of the patients had positive findings in their cholangiography. 13 patients had CBD stones, 14 had obstruction of gallbladder and 6 had bile leak. All positive findings required changed in management. CONCLUSION: PCC is a safe procedure. Cholangiography, should be performed in every patient who was managed by PCC since it might change the management in third of the cases.

Should the management approach to the anterior abdominal stab wound be different in patients with self-inflicted abdominal injury?

BACKGROUND: Self-inflicted injury is a leading cause of death worldwide. It is hypothesized that due to instincts for self-preservation, the severity of abdominal injury would be decreased following suicidal self-stabbing in comparison to stab wounds from assault, and therefore a more conservative management might be considered. METHODS: All patients with isolated abdominal stab wound (SW) admitted to 19 Trauma Centers in Israel between the years 1997 and 2018 were included in the study. Patients with self-inflicted abdominal SW (Group I) were compared to victims with abdominal SW following assault (Group II). RESULTS: Group I included 9.4% (314/3324) of patients eligible for this study. Compared to Group II, Group I patients were older (median: 39 years, IQR 28,52 vs. 24 years, IQR 19,33; p<0.001), had more females (28.7% vs 4.9%, p <0.001), had longer length of hospitalization (median: 3 days vs. 2 days; p<0.001), underwent surgery more frequently (55.4% vs. 37.4%; p<0.001), and had higher mortality (2.9% vs. 0.7%; p=0.003). Possible covariates for mortality were examined and following logistic regression, self-inflicted injury remained associated with higher death rates compared to assault (OR 4.027, CI95% 1.380, 11.749; p=0.011). CONCLUSION: In this study, patients with isolated self-inflicted abdominal injuries had higher mortality and more frequently underwent abdominal surgery.

Thoracic vertebrae fracture: Is it an indicator of abdominal injury?

PURPOSE: Traumatic vertebral fracture accounts for 10-15% of trauma related admissions. While the correlation between lumbar vertebral fractures and abdominal injuries is well established, the relationship between thoracic vertebral fractures (TVF) and abdominal injuries is comparatively less well elucidated. Using a large national trauma database, we aimed to examine the incidence and severity of associated abdominal injuries in blunt trauma patients suffering from TVF. METHODS: A retrospective cohort study using the Israeli National Trauma Registry was conducted. Patients with thoracic vertebrae spine fractures following blunt mechanisms of trauma between 1997 and 2018 were examined, comparing the incidence and severity of associated intraabdominal organs injuries with and without TVF. Demographics and outcomes between the two cohorts were compared. RESULTS: From 362,924 blunt trauma patients, 4967 (1.37%) had isolated TVF. Mean age was 49.8 years and 61.9% were males. The most common mechanism of injury was fall following by MVC. The patients with TVF had significantly higher rates of increased ISS score (ISS > 16, 28.45% vs. 10.42%, p < 0.001) and higher mortality rate (3.5% vs. 2%, p < 0.0001). Patients with TVF had 2-3 times more intraabdominal organ injuries (p < 0.001). The most commonly injured organ was spleen (3.28%); followed by liver (2.64%) and kidney (1.47%). An analysis of non-isolated thoracic spine fractures showed same distribution in age, ISS, mechanisms, patterns of intra-abdominal injury, mortality rate and laparotomy rate. CONCLUSION: Clinicians should have an elevated suspicion for intra-abdominal injuries when a thoracic spine fracture is identified, which may necessitate further evaluation.

En bloc resection for malignant colouterine fistula.

Colouterine fistula is a rare clinical entity. A literature search revealed only a few reports dealing with this complex problem, mostly resulting as a complication of diverticular disease of the colon. During a 4-month period, we diagnosed and successfully treated 2 women with a malignant colouterine fistula originating from a primary colorectal carcinoma invading the uterus. We herein report on our experience dealing with this kind of pathology, with special emphasis on the surgical technique used to resect the tumoral mass "en bloc".

Bicycle-related injuries in children: disturbing profile of a growing problem.

CONTEXT: We observed a changing pattern of bicycle-related injuries in children, with the focus changing from head trauma to thoracic and abdominal injuries, and a trend to increasingly severe injuries. OBJECTIVE: To assess the changing injury pattern, and investigate the development of preventive measures to improve safety. DESIGN, SETTING, AND PARTICIPANTS: Retrospective record review of 142 paediatric patients admitted to our Department of Paediatric Surgery between 1996 and 2005 following bicycle-related injuries. Clinical, laboratory, diagnostic, and therapeutic aspects were analysed. Additional information concerning children's bicycle-related injuries in Israel was obtained from the Gertner Institute (Israel National Center for Trauma and Emergency Medicine Research) and from Beterem (The National Center for Children's Safety & Health, the Safe Kids Israeli Chapter) National Report on Child Injuries in Israel 2006. MAIN OUTCOME MEASURES: The nature and severity of injuries were reviewed, and two 5-year periods compared-from 1996 to 2000 (53 children-Group 1), and from 2001 to 2005 (89 children-Group 2). RESULTS: Head trauma was more common in the Group 1 patients (52.6% vs. 45.2%), but skull fractures and intracranial haemorrhage occurred more frequently in Group 2 (28.5% vs. 16.7%; 21.3% vs. 8.3%, respectively). Injury to the stomach or duodenum, kidneys and liver were all more common in Group 2. Splenic injury occurred with equal frequency in both groups, but more severe injuries were seen in Group 2. More children in Group 2 required intensive care (31% vs. 19.3%). CONCLUSIONS: There is a changing pattern of bicycle-related injuries in children, with chest and abdominal injuries dominating, and an increasing incidence of more severe injury. These findings are important in decision-making regarding preventive measures.

Early detection of life-threatening intracranial haemorrhage using a portable near-infrared spectroscopy device.

OBJECTIVE: To determine whether infrared spectroscopy allows early recognition of epidural and subdural haematomas among trauma patients. METHODS: Injured people admitted to two trauma units were enrolled in a prospective multicentre observational study, and infrared spectroscopy was performed before computed tomography of the head as a part of their initial evaluation. Subsequent CT findings suggestive of epidural or subdural haematoma served as controls. RESULTS: Over 12 months, 110 patients were enrolled; 64 (58.1%) were men and 46 (41.9%) were women. Mean age was 56.2 years, and mean Glasgow Coma Scale on admission was 12.6. Infrared spectroscopy was 90.5% sensitive and 95.5% specific for epidural and subdural haematoma. Positive and negative predictive values were 82.6% and 97.7%, respectively. CONCLUSIONS: Infrared spectroscopy allows early recognition of epidural and subdural haematomas in trauma cases. Further studies are needed to evaluate whether immediate confirmation or exclusion of epidural and subdural haematomas with portable near-infrared spectroscopy devices improves the decision-making process in the treatment of severely injured people.

Effect of methylene blue on resuscitation after haemorrhagic shock.

OBJECTIVE: To compare prehospital hypotensive resuscitation with volume resuscitation, and find out whether reagents that inhibit free-oxygen radical formation, such as methylene blue, can improve resuscitation and survival. DESIGN: Randomised controlled trial. SETTING: Animal laboratory, Israel. ANIMALS: 48 adult male Wistar rats. INTERVENTIONS: After 30 minutes of controlled haemorrhage, rats were subjected to 60 minutes of uncontrolled haemorrhage with simultaneous resuscitation. Hartmann's solution alone, or with blood or with a bolus of methylene blue were infused to maintain the mean arterial pressure (MAP) at 80 or 40 mm Hg. Then haemorrhage was stopped and Hartmann's solution plus whole blood were infused to obtain a MAP that was within normal limits. MAIN OUTCOME MEASURES: Volumes of shed blood and resuscitation fluids, MAP, packed cell volume, blood pH and base deficit, and survival. RESULTS: During uncontrolled haemorrhage. a MAP of 80 mm Hg could not be reached in animals resuscitated with Hartmann's solution alone, and all died. All the rats given Hartmann's solution with a bolus of methylene blue or with whole blood achieved a higher MAP. MAP of 40 mm Hg was attained in all animals regardless of the resuscitation fluid. Only 15 of 24 animals resuscitated to a MAP of 80 mm Hg survived, compared with 22 survivors of the 24 rats resuscitated to a MAP of 40 mm Hg (p <0.04). Methylene blue or whole blood drastically reduced the volumes of shed blood and of fluids required, and moderated the reduction in packed cell volume, particularly during hypotensive resuscitation. CONCLUSION: Hypotensive protocols should be used to improve survival. Methylene blue given with the electrolyte solutions could negate their detrimental effects during resuscitation.

Antibiotic prophylaxis in umbilical and incisional hernia repair: a prospective randomised study.

OBJECTIVE: To find out if preoperative prophylaxis would reduce infection rates after umbilical and incisional hernia repair. DESIGN: Randomised controlled trial. SETTING: Teaching hospital, Israel. SUBJECTS: 35 Patients who presented with umbilical (n = 19) or incisional (n = 16) hernias during a period of 8 months. INTERVENTIONS: Cefonicid 1 g was given by intravenous infusion to alternate patients 30 minutes before the operation. MAIN OUTCOME MEASURES: Wound infection. RESULTS: The groups were comparable for age, body mass index, grade of surgeon, operating time, and size of hernial ring. The wound infection rates were 0/8 compared with 4/8 for incisional hernia repairs (p = 0.08) and 1/9 compared with 4/10 for umbilical hernia repairs (p = 0.3). The overall rate was 1/17 compared with 8/18 (p = 0.02). CONCLUSIONS: Single dose antibiotic puphylaxis seems to exert a beneficial effect on the wound infection rate after umbilical and incisional hernia repair.
