Slipping rib syndrome: case report of an iatrogenic result following video-assisted thoracic surgery and chest tube placement.

The aim of this case report is to shed light on slipping rib syndrome (SRS), a painful and overlooked condition. A 62-year old man reported intermittent, self-resolving sharp rib pain that began after a video-assisted thoracic surgery and chest tube placement 4 years prior to presentation. The patient's pain was associated with a rigid protrusion in the right upper quadrant, and home use of acetaminophen provided no relief. After physical examination, multiple imaging and lab tests, the patient was diagnosed with SRS and was referred to physical therapy and thoracic surgery for further evaluation. SRS is an under-recognized cause of upper abdominal and lower thoracic pain that should be considered if a patient's history includes previous trauma or abdominal surgery.

Lay abstract This is a case report of slipping rib syndrome (SRS). It is a painful medical condition. A 62-year old man after a video-assisted thoracic surgery and chest tube placement had recurrent, self-resolving sharp rib pain. The pain was associated with a rigid lump in the right lower rib cage. Acetaminophen and narcotics provided no relief. After physical examination, multiple imaging and lab tests, he was diagnosed with SRS and was referred to physical therapy and thoracic surgery for further evaluation. SRS is an under-recognized cause of rib pain that should be considered if a patient's history includes previous trauma or abdominal surgery.

Pilot study of intraoperative ultrasound-guided instrument placement in nerve transection surgery for peripheral nerve pain syndromes.

Surgical transection of sensory nerves in the treatment of intractable neuropathic pain is a commonly performed procedure. At times these cases can be particularly challenging when encountering obese patients, when targeting deeper nerves or those with a variable branching pattern, or in the case of repeat operations. In this case series, the authors describe their experience with ultrasound-guided surgical instrument placement during transection of a saphenous nerve in the region of prior vascular surgery in 1 patient and in the lateral femoral cutaneous nerve in 2 obese patients. The authors also describe this novel technique and provide pilot data that suggests ultrasound-assisted surgery may allow for complex cases to be completed in an expedited fashion through smaller incisions.

Complications of ventricular entry during craniotomy for brain tumor resection.

OBJECTIVE Recent studies have demonstrated that periventricular tumor location is associated with poorer survival and that tumor location near the ventricle limits the extent of resection. This finding may relate to the perception that ventricular entry leads to further complications and thus surgeons may choose to perform less aggressive resection in these areas. However, there is little support for this view in the literature. This study seeks to determine whether ventricular entry is associated with more complications during craniotomy for brain tumor resection. METHODS A retrospective analysis of patients who underwent craniotomy for tumor resection at Henry Ford Hospital between January 2010 and November 2012 was conducted. A total of 183 cases were reviewed with attention to operative entry into the ventricular system, postoperative use of an external ventricular drain (EVD), subdural hematoma, hydrocephalus, and symptomatic intraventricular hemorrhage (IVH). RESULTS Patients in whom the ventricles were entered had significantly higher rates of any complication (46% vs 21%). Complications included development of subdural hygroma, subdural hematoma, intraventricular hemorrhage, subgaleal collection, wound infection, urinary tract infection/deep venous thrombosis, hydrocephalus, and ventriculoperitoneal (VP) shunt placement. Specifically, these patients had significantly higher rates of EVD placement (23% vs 1%, p < 0.001), hydrocephalus (6% vs 0%, p = 0.03), IVH (14% vs 0%, p < 0.001), infection (15% vs 5%, p = 0.04), and subgaleal collection (20% vs 4%, p < 0.001). It was also observed that VP shunt placement was only seen in cases of ventricular entry (11% vs 0%, p = 0.001) with 3 of 4 of these patients having a large ventricular entry (defined here as entry greater than a pinhole [< 3 mm] entry). Furthermore, in a subset of glioblastoma patients with and without ventricular entry, Kaplan-Meier estimates for survival demonstrated a median survival time of 329 days for ventricular entry compared with 522 days for patients with no ventricular entry (HR 1.13, 95% CI 0.65-1.96; p = 0.67). CONCLUSIONS There are more complications associated with ventricular entry during brain tumor resection than in nonviolated ventricular systems. Better strategies for management of periventricular tumor resection should be actively sought to improve resection and survival for these patients.
