Management of persimmon bezoars (diospyrobezoars).

Since 1946, 20 men and one woman aged 40 to 76 years (average 57) were operated upon for complications of diospyrobezoars. Shortly after eating persimmons, 11 (52.4%) had severe abdominal cramping, anusea, vomiting, and pyrexia. Twelve of 17 (70.9%) with gastric bezoars had hematemesis or melena caused by an associated gastric ulcer, while five (29.1%) had only moderate dyspepsia. In four (19.1%), the bezoar had lodged in the ileum, causing obstruction. Enzymatic therapy is indicated in those with minor symptoms. Gastrotomy or gastrotomy with bezoar removal and wedge resection of the gastric ulcer is recommended when enzymatic therapy fails, or when there is gastric outlet obstruction or marrise hemorrhage. Emergency exploration with removal is necessary when the persimmon bezoar causes ileal obstruction.

Accumulation of numerous cellular T-DNA sequences in the genus Diospyros by multiple rounds of natural transformation.

Horizontal gene transfer (HGT) is an important phenomenon in the evolutionary history of plants. Natural transformation by Agrobacterium is a special case of HGT and leads to the insertion of cellular T-DNA (cT-DNA) sequences, for example, in Diospyros lotus. The genus Diospyros contains about 795 species with economically important members, like different types of persimmon (D. kaki, D. lotus, and D. virginiana) and ebony (e.g., D. ebenum). Whole genome sequences (WGS) from D. kaki, D. oleifera, D. lotus, and D. virginiana were investigated for cT-DNAs. These four species belong to one clade and contain 15 different cT-DNAs (DiTA to DiTO). The hexaploid species D. kaki cv. "Xiaoguo-tianshi" contains seven types of cT-DNA (DiTA to DiTG) on 27 of 42 homeologs, adding up to 628 kb of cT-DNA. Five of these seven cT-DNAs are non-fixed, as shown by empty chromosomal insertion sites. The evolutionary history of the Diospyros cT-DNAs was reconstructed using the divergence of their inverted repeats. Insert age varied from 3 to 12 million years. Partial cT-DNA sequences were detected in 35 additional species from five Diospyros clades. Our data highlight the unexpectedly large scale of natural Agrobacterium transformation in Diospyros and demonstrate the necessity of whole genome approaches for studies on the origin and evolution of cT-DNAs.

Phytobezoar: a recurring abdominal problem.

Phytobezoars often follow gastric surgery for peptic ulcer disease. Billroth I resections have a high incidence of gastric bezoars, especially if accompanied by vagotomy. The larger opening of a Billroth II resection may result in intestinal bezoars with obstruction in the narrow terminal ileum. Gastric bezoars can be treated with enzymes or can be broken up by endoscopy; only rarely is operative removal required. Intestinal bezoars can be treated by long-tube and enzyme instillation but usually require laparotomy. If possible, the bolus should be milked into the cecum, but enterotomy or even resection may be required. Prevention is the best treatment and can be carried out by instructing patients who have had gastric surgery to avoid the fibrous portion of oranges and grapefruit and to avoid persimmons.

Phytobezoar: an uncommon cause of small bowel obstruction.

Phytobezoars are an unusual cause of small bowel obstruction. We report 13 patients presenting with 16 episodes of small bowel obstruction from phytobezoars. Eleven patients had previously undergone surgery for peptic ulceration (eight truncal vagotomy and pyloroplasty). A history of ingestion of persimmon fruit was common and the majority of cases presented in the autumn when this fruit is in season. One phytobezoar causing obstruction at the third part of the duodenum was removed by endoscopic fragmentation, while an episode of jejunal obstruction was precipitated by endoscopic fragmentation of a gastric bezoar. Twelve patients underwent surgery for obstruction on 15 occasions, with milking of the phytobezoar to the caecum performed in ten, enterotomy and removal in four and resection in one patient. Associated gastric phytobezoars were found in two cases and multiple small bowel bezoars in two other cases. These were removed to prevent recurrent obstruction. Phytobezoar should be considered preoperatively as a cause of obstruction in patients with previous ulcer surgery. Wherever possible milking of a phytobezoar to the caecum should be performed. Careful assessment for other phytobezoars should be made. Prevention of phytobezoars is dependent upon dietary counselling of patients by surgeons after gastric resection or vagotomy and drainage for peptic ulcer.

Report of a case of a giant phytobezoar in a patient with a duodenal bulb ulcer.

A case of a large phytobezoar (750 g weight and with the length of 29 cm) due to Khormalou (Persimmon) is being reported in a young patient with chief complaint of abdominal pains and concomitant duodenal ulcer. Review of the literature in this subject shows that bezoars of this size and weight are relatively rare in healthy individuals.

[Clinico-radiological studies on 3 cases of bezoars].

Three cases of phytobezoar (2 in the stomach and 1 obstructing the ileum) are presented. The bezoar described are due to persimmon in one cases and to applies in two cases and have been observed during a period of over 10 years.
