The exact aetiology of sigmoid volvulus in Parkinson's disease (PD) remains unclear. A multiplicity of factors may give rise to decreased gastrointestinal function in PD patients. Early recognition and treatment of constipation in PD patients may alter complications like sigmoid volvulus. Treatment of sigmoid volvulus in PD patients does not differ from other patients and involves endoscopic detorsion. If feasible, secondary sigmoidal resection should be performed. However, if the expected surgical morbidity and mortality is unacceptably high or if the patient refuses surgery, percutaneous endoscopic colostomy (PEC) should be considered. We describe an elderly PD patient who presented with sigmoid volvulus. She was treated conservatively with endoscopic detorsion. Surgery was consistently refused by the patient. After recurrence of the sigmoid volvulus a PEC was placed.
We describe a case of isolated gallbladder contusion after deceleration trauma. On admission, no evident signs of intra-abdominal injury were present. However, after 24 h observation an explorative laparotomy was performed because of persistent abdominal complaints. A contusion of the gallbladder wall was found with intraluminal haematoma and a cholecystectomy was performed. Isolated injury of the gallbladder after blunt trauma is extremely rare. Risk factors are distention of the gallbladder, deceleration trauma and the presence of a relatively mobile gallbladder. Clinical signs often are very subtle. Delayed presentation is common with signs of hemobilia or obstruction due to intraluminal clots. Ultrasound and computed tomography are suitable diagnostic tools. However, the diagnosis is often missed if no other injuries are present. Signs pointing to gallbladder injury are a collapsed gallbladder with pericholecystic fluid or a hydroptic gallbladder with intraluminal hematoma. Hepatobiliary scintigraphy or angiography might be necessary if additional injuries are suspected. The choice of treatment depends on the kind of injury. Contusion of the gallbladder allows conservative treatment, but in case of a rupture, surgery will be necessary. Accompanying bile duct injuries can be treated by endoscopic stenting. If active arterial bleeding is present, selective embolization can be performed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
