Unsedation colonoscopy can be not that painful: Evaluation of the effect of “Lamaze method of colonoscopy”

AIM: To evaluate the pain relieving effect of intervention with "Lamaze method of colonoscopy" in the process of colonoscopy.METHODS: Five hundred and eighty-five patients underwent colonoscopy were randomly divided into three groups, Lamaze group, anesthetic group and control group. Two hundred and twenty-four patients of Lamaze group, the "Lamaze method of colonoscopy" were practiced in the process of colonoscopy. The Lamaze method of colonoscopy is modified from the Lamaze method of childbirth, which helped patients to relieve pain through effective breathing control. One hundred and seventy-eight patients in anesthetic group accepted sedation colonoscopy. For 183 patients in control group, colonoscopy was performed without any intervention. The satisfactory of colon cleaning, intestinal lesions, intubation time, success ratio, pain grading and complications were recorded. All data were statistically analyzed.RESULTS: There were no significant differences at base line of the three groups(P > 0.05). Anesthetic group shows advantage in intubation time than the other two groups(P < 0.05). Lamaze group shows no advantagein intubation time than that in control group(P > 0.05). The anesthetic group showed an apparent advantage in relieving pain(P < 0.01). Therefore, the "Lamaze method of colonoscopy" performed in colonoscopy could relieve pain effectively comparing with control group(P < 0.05). The patients in anesthetic group had the highest incidence of complications(P < 0.05).CONCLUSION: The performance of the "Lamaze method of colonoscopy" in the process of colonoscopy could relieve patients' pain, minimize the incidence of complications, and is worthy promotion in clinical practice.

Application of blunt dissection in ESD of a gastric submucosal tumor

We performed endoscopic submucosal dissection of a gastric fundus tumor.It was difficult to strip the tumor completely due to space limitation,and we used blunt dissection to remove the tumor quickly and safely.Firstly,the basal area of the 2.5 cm submucosal tumor located in the gastric fundus was cut open,and the mucosa was dissected.The tumor was difficult to peel,therefore,a snare was used and the tumor was pulled and tightened slightly.Short electronic coagulation was used during the procedure.The tumor was then bluntly dissected.This method ensured rapid and complete removal of the tumor.
