ABSTRACT
To investigate the clinical and endoscopic characteristics and endoscopic treatment efficacy of cap polyposis, data of 14 patients (56 polyps) who were histologically diagnosed as having cap polyposis after endoscopic submucosal dissection (ESD) or endoscopic mucosal resection (EMR) in Beijing Friendship Hospital from June 2017 to February 2021 was retrospectively analyzed. Of the 14 patients, 8 were males and 6 were females. The age ranged from 14 to 74 years, including 7 cases of <60 years old and 7 cases of ≥60 years old. 7 patients (50.0%) had clinical manifestations. Four cases had multiple polyps and 10 cases (71.4%) had single polyps. There were 42 polyps (75.0%) located in the rectum, 13 (23.2%) in the sigmoid colon and 1 in the transverse colon. According to the classification of Yamada, 44 polyps (78.6%) were type Ⅰ, 3 polyps were type Ⅱ, 5 polyps were type Ⅲ and 4 polyps were type Ⅳ. Under endoscopy, there were 41 polyps (73.2%) with obvious white cap-like coverings on the surface and 23 polyps with obvious hyperemia and redness on the mucosa, 8 of which were both visible. Two cases were treated with ESD and 12 cases were treated with EMR, all of which were completely excised. No bleeding, perforation, infection or other complications occurred during and after operation. The clinical symptoms of 7 patients were relieved. During the follow-up period, 11 cases (78.6%) completed colonoscopy, and no polyp recurrence was found. In conclusion, there is no gender or age difference in patients of cap polyposis. It is usually single and located in the rectum and sigmoid colon with Yamada type Ⅰ. The surface of lesions is mostly covered with white cap. Patients may have no obvious clinical symptoms. Treatment of ESD and EMR is safe and effective for cap polyposis.
ABSTRACT
Objectives To compare total laparoscopic gastrectomy with intracorporeal hand-sewn Gl reconstruction and laparoscopy-assisted gastrectomy for gastric cancer. Methods Between July 2009 and July 2010, 21 patients of gastric cancer underwent total laparoscopic D2 radical gastrectomy with intracorporeal hand-sewn reconstruction and 28 did laparoscopy-assisted D2 radical gastrectomy in Xijing Hospital of Digestive Diseases. All patients were operated on by an experienced surgeon. Patient demographics, TNM stage, location of tumor, the intraoperative and postoperative details of the two groups were compared. Results In the 21 patients undergoing total laparoscopic gastrectomy, there were 15 of distal gastrectomy and 6 of total gastrectomy, compared with 21 and 7 in laparoscopy-assisted group. In total laparoscopic group, intracorporeal hand-sewn technique was used for gastro-jejunal and jejuno-jejunal (J-J)anastomosis, and 25 mm circular stapler was used for esophago-jejunal anastomosis. The operation time was significant longer in total laparoscopic group than in laparoscopy-assisted group of (279 ± 65 ) min vs.(232 ±40) min (P ＜ 0.05 ). No significant difference was observed between the two groups in proximal margin [(5.7 ± 1.5 )cm vs. (5.1 ± 1.4) cm, P ＞ 0.05] and distal margin [( 3.1 ± 0.9 )cm vs. ( 2.9 ±0.9) cm,P ＞0.05]. The iv narcotic use in laparoscopy-assisted group was 1.8 d but it was not used in total laparoscopic group. The first passing flatus was on day 3 in total laparoscopic group compared with 4.8 d in laparoscopy-assisted group. Both groups had 2 postoperative early complications, one intra-abdominal infection and one lung infection in total laparoscopic group compared with one wound infection and one lung infection in laparoscopy-assisted group. There was no anastomosis-related complications after 4 months of follow-up. Conclusions The operation time and postoperative early complication was acceptable for selected patients treated by total laparoscopic D2 radical gastrectomy with intracorporeal hand-sewn GI tract reconstruction in hands of experienced laparoscopic surgeon.
