Bezoars, and to lesser extent phytobezoars, are among the rare causes of small bowel obstruction. A bezoar generally describes retained concretions of indigestible foreign material that accumulate and conglomerate in the gastrointestinal tract, most commonly in the stomach. We present an unusual case of phytobezoar-induced sub-acute small bowel obstruction originating from unfamiliar plant material in a 74-year-old woman. The past history was insignificant regarding comorbidities other than depression. Presenting complaints were history of abdominal pain and vomiting. Imaging studies and physical examination suggested small bowel obstruction. The patient underwent exploratory laparotomy after 1 day of conservative treatment. We found a 4.5 cm obstructing phytobezoar intraoperatively. The undigested plant material caused the obstruction. Postoperatively, the plant was identified as Scorzonera papposa. The patient was discharged uneventfully. The elderly patients should avoid semi-cooked vegetables, plants of unknown origin and high-fibre diet.

The aim of this study was to assess ablation outcome after a second ablation dose and compare the ablation rate after low and high reablation doses of iodine-131 ((131)I) after failure of the first ablation with 3700 MBq.The study included 81 patients with papillary thyroid cancer; they failed to achieve complete ablation after a first ablative dose of 3700 MBq. Their first follow-up (131)I whole-body scan carried out 6-9 months after ablation showed small residual functioning tissue in the thyroid bed, with no functioning metastases. This is associated with unsuppressed serum thyroglobulin level (Tg) higher than 2 ng/ml. The patients received a second ablation dose, which was low (1110 MBq) in 37 patients and high in the remaining 44 patients (2960 MBq in 36 patients and 3700 MBq in eight patients). A whole-body scan and Tg level assessment were carried out 6-9 months later. The criteria for complete ablation included absence of residual functioning thyroid tissue and a Tg level lower than 2 ng/ml.The overall successful complete ablation rate after the second reablation dose was 75%. This was achieved in 27 of 37 patients (73%) who received a low reablation dose and in 34 of 44 patients (77%) who received a high reablation dose; no statistically significant difference was found between the two groups (P0.05).In patients with papillary thyroid cancer who failed to achieve complete ablation after the first ablation dose of 3700 MBq, the overall complete ablation rate after both a low and a high second (131)I dose was 75%, with no statistically significant difference in ablation rate between low (1110 MBq) and high (2960 and 3700 MBq) doses (73 and 77%, respectively).
