Phytobezoars are plant fibre concretions occurring in the stomach as a complication following some types of gastric surgery. Symptoms include distension, pain and vomiting. Ulceration, gastric bleeding and even perforation can occur. If untreated, they result in a significant mortality. Dissolution of the phytobezoar can be achieved without operative intervention. Enzymes and especially cellulase help to break up the mass and it can then be aspirated or allowed to pass on. Five patients with phytobezoars were thus treated and the cellulase method was confirmed to be simple, safe and effective.
植物性胃石是在某些类型的胃部手术后作为并发症出现在胃内的植物纤维凝结物。症状包括腹胀、疼痛和呕吐。可能会发生溃疡、胃出血甚至穿孔。如果不进行治疗，会导致相当高的死亡率。无需手术干预即可实现植物性胃石的溶解。酶尤其是纤维素酶有助于分解胃石，然后可以将其吸出或使其排出。五例植物性胃石患者因此得到治疗，纤维素酶法被证实简单、安全且有效。
