Outcome after laparoscopic versus open wedge resection for suspected gastric gastrointestinal stromal tumors: A matched-pair case-control study.

BACKGROUND: Laparoscopic resection of gastric gastrointestinal stromal tumors (GISTs) has been shown by several retrospective studies to be technically feasible and associated with favorable outcomes when compared to the open approach. This study aims to mitigate potential selection bias by performing a case control study of laparoscopic (LWR) versus open wedge resection (OWR) matched by resection type, location and tumor size. METHODS: We retrospectively identified 50 consecutive patients who underwent LWR for a suspected gastric GIST from a prospective database and matched this cohort with 50 patients who underwent OWR. RESULTS: There was no statistical difference between the key baseline clinicopathological features of patients' who underwent LWR versus OWR. Patients who underwent LWR had longer operating times [150 (range, 65-270) minutes vs 92.5 (25-200) minutes, P < .001] but decreased median blood loss [0 (0-300) ml vs 0 (0-1200) ml, P = .015], decreased frequency of intraoperative or postoperative blood transfusion [1 (2%) vs 8 (16%), P = .031], decreased median time to liquid diet [2 (0-5) vs 3 (1-7) days, P < .001], decreased median time to solid diet [3 (1-6) vs 5 (2-11) days, P < .001] and decreased postoperative stay [4 (2-10) vs 4.5 (3-17), P < .001] compared to OWR. There was no difference in oncological outcomes such as frequency of close margins (≤ 1 mm) and recurrence-free survival. CONCLUSION: This matched case-control study provides supporting evidence that LWR results in superior perioperative outcomes compared to OWR without compromising on oncological outcomes.

Limited magnetic resonance imaging (MRI) and the occult hip fracture.

INTRODUCTION: Diagnosis of hip fracture is normally readily made from clinical evaluation and plain radiographs. Occasionally, clinical suspicion of fracture is not confirmed on plain X-rays. MATERIALS AND METHOD: Between January 2001 and March 2002, 422 patients were admitted to our department for post-traumatic hip pain. The diagnosis of hip fracture was unequivocally made in 365 patients (86%). Fifty-seven (14%) patients had a negative or equivocal radiograph. RESULTS: Limited magnetic resonance imaging (MRI) of the hip in this group of 57 patients confirmed that 8 (14%) sustained a femoral neck fracture, while 5 (9%) had an intertrochanteric fracture. In 19 patients (33%), some other pathology was found, mainly stable fractures of the femoral trochanters and pubic rami. Overall, 32 scans (56%) were positive and 25 (44%) were negative. Limited MRI detected patients with undisplaced hip fractures and identified them as candidates for surgery. CONCLUSION: The use of MRI in this specific and 'limited' way provides orthopaedic surgeons with a rapid, accurate and cost-effective diagnostic tool in this clinical scenario. Definitive diagnosis allows the correct management plan to be implemented early. We recommend that patients, who have significant hip pain following injury but indeterminate plain radiographs, undergo a limited MRI scan as a matter of routine.
