AIM Comparison of transanal excision (TE) and transanal endoscopic microsurgery (TEM) of rectal adenomas (RA) has rarely been performed. METHOD From 1990 to 2007, the results of TE (43 RA) and TEM (216 RA) were compared. Rectal adenomas were matched for diameter and distance from the anal verge. RESULTS Operation time was 47.5 min for TE and 35 min for(More)
twine is the second homolog of the fission yeast gene cdc25 to be found in Drosophila. Both string and twine cDNAs can rescue a temperature-sensitive cdc25 mutation in fission yeast, but not a deletion. We detect the expression of string but not twine transcripts in the proliferating cells of newly cellularized embryos, in third instar larval brains, and in(More)
A discussion is presented of traumatic anterior dislocation of the hip joint on the basis of three representative case reports. One patient had an iliac or pubic dislocation, the other two were obturator dislocations, including one with an associated femoral head fracture. All three patients were treated without surgery. After an average follow-up time of(More)
BACKGROUND A popliteal artery aneurysm (PAA) has been described as a 'sinister harbinger of sudden catastrophe'. This review seeks to provide data regarding the epidemiological aspects, natural history, clinical presentation and results of treatment to help clinicians make appropriate decisions. METHODS A systematic review of data in the English language(More)
In a retrospective study 42 patients with asymptomatic popliteal artery aneurysm were followed without surgery to identify variables predicting the risk of complications. The mean aneurysm size was 3.1 cm. Abnormal ankle pulses were found in 18 of the 42 limbs in which an asymptomatic popliteal aneurysm was present. Follow-up was complete (mean 6.2 years).(More)
BACKGROUND Incisional hernia is one of the most frequent postoperative complications after abdominal surgery. Patients with an abdominal aortic aneurysm and patients with a body mass index of 27 or higher have an increased risk to develop incisional hernia. Primary mesh augmentation is a method in which the abdominal wall is strengthened to reduce(More)
BACKGROUND AND PURPOSE Information on the long-term fate of patients with chronic lower limb ischemia is limited. We investigated the long-term risk of the first ischemic and hemorrhagic cerebral stroke in patients on long-term anticoagulant therapy after reconstruction for chronic limb ischemia. METHODS In a retrospective study, 376 consecutive patients(More)
The natural history of aneurysmal disease was analyzed in 50 patients who were treated for 71 popliteal aneurysms. No patients were lost to follow-up (mean, 5.0 years). Initially, 25 popliteal aneurysms (25/71; 35%) were treated nonsurgically, and 46 (46/71; 65%) were treated surgically. Complications developed in 12 of the 21 asymptomatic popliteal(More)
BACKGROUND With the implementation of competency-based curricula, Objective Structured Assessment of Technical Skills (OSATS) increasingly is being used for the assessment of operative skills. Although evidence for its usefulness has been demonstrated in experimental study designs, data supporting OSATS application in the operating room are limited. This(More)
Transanal endoscopic microsurgery (TEM) is considered a curative option for selected T1 rectal cancer. Although TEM is safe, local recurrence (LR) rates after TEM are unacceptably high. Evidence on selection criteria, however, is not abundant. To expand evidence on low- versus high-risk T1 rectal cancer with respect to LR, this study aimed to identify(More)
