Abstract

Rationale:

Colonic lipomas are uncommon benign submucosal adipose tumorsthat are usually asymptomatic. Large lipomas can cause symptoms require treatment in principle. We report 1 case of giant colonic lipoma removed with endoloop-assisted unroofing technique instead of conventional surgical bowel resection.

Patient Concerns:

A 62-year-old female patient presented with intermittent abdominal discomfort for 1 month.

Diagnosis:

The patient was diagnosed as having a giant colonic lipoma.

Intervention:

Endoscopic resection with endoloop-assisted unroofing technique was performed. On the 22nd day after resection, intestinal obstruction occurred by shedding mass was found; the symptoms of this patient disappeared soon after removal of the mass by endoscopy.

Outcomes:

A follow-up colonoscopy 6 months later showed a scarred mucosa at the ligation site and no residual lipoma was observed.

Lessons:

Endoscopic resection with endoloop-assisted unroofing technique remains a viable option for giant lipomas; however, postoperative intestinal obstruction caused by shedding mass should be noted.

The Colonization of Land

The Colonization of Land

Changes in the environment of the early Earth drove the evolution of organisms. As prokaryotic organisms in the oceans began to photosynthesize, they produced oxygen. Eventually, oxygen saturated the oceans and entered the air, resulting in an increase in atmospheric oxygen concentration, known as the oxygen revolution approximately 2.3 billion years ago. Therefore, organisms that could use oxygen for cellular respiration had an advantage. More than 1.5 years ago, eukaryotic cells and...

Data Reporting and Recording

Data Reporting and Recording

Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

Endoscopic Studies II: Thoracocentesis

Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Endoscopic Procedures I: Esophagogastroduodenoscopy

An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:
