Patients
We conducted an observational retrospective study which included all
patients with PJS from Zhejiang Provincial People’s Hospital (People’s
hospital of Hangzhou medical college, Hangzhou, China), a tertiary-care
referral center, who had undergone SBE for polypectomy between January
2018 and March 2021. Medical records of all the included patients were
retrospectively reviewed. The following data were collected: age,
gender, history of laparotomy, the method of SBE insertion, number of
SBE procedures performed, maximum size and number of the resected polys,
and complications. A clinical diagnosis of PJS can be made when any one
of the following was present: 1) two or more histologically confirmed
PJS polyps; 2) any number of PJS polyps detected in one individual who
has characteristic mucocutaneous pigmentation or a family history of PJS
in close relative(s); and 3) characteristic mucocutaneous pigmentation
in an individual who has a family history of PJS in close
relative(s)[20]. The study protocol was approved by the Ethics
Committee of Zhejiang Provincial People’s Hospital (Approval Number
2021QT244). This study was reviewed
and approved by the Institutional. All information of patients in these
records remained confidential.
