Factors Affecting Adenoma Risk Level in Patients with Intestinal Polyp and Association Analysis

Objective. To explore the factors affecting the adenoma risk level in patients with intestinal polyp and association. Methods. The clinical data of 3,911 patients with intestinal polyp treated in our hospital from January 2018 to January 2021 were retrospectively analyzed, all patients accepted the histopathological examination, their risk of suffering from adenoma was evaluated according to the results of pathological diagnosis, and relevant hazard factors affecting adenoma risk level in them were analyzed by multifactor logistic regression analysis. Results. The results of multifactor logistic analysis showed that male gender, age ≥60 years, number of polyps >3, diameter ≥2 cm, onset at colon, and physiologically tubulovillous adenoma were the hazard factors causing high-grade adenoma risk in patients with intestinal polyp. Conclusion. There are many risk factors causing high-grade adenoma in patients with intestinal polyp, and therefore, the screening for high-risk population shall be enhanced to reduce the potential of carcinomatous change in such patients.

Squamous Metaplasia in Colonic Tubulovillous Adenoma: A Three Case Series and review of literature

Introduction/Objective Although squamous metaplasia of colonic tubulovillous adenoma is a rare phenomenon, colorectal polyps can show focal squamous metaplasia. While the exact cause in unknown, it has been suggested that mechanical irritation, torsion and chronic inflammation may predispose to squamous metaplasia within large colonic polyps. Methods/Case Report We observed this finding in two men and one woman with colorectal polyps who underwent endoscopic mucosal resection in a three-week timeframe. In two cases the polyps were rectal, while in the third case, it was located in the descending colon. Polyp size ranged from 1-5 cm and were semi-pedunculated. Histologically, all three lesions were tubulovillous adenomas with focal high-grade dysplasia and multiple foci of squamous metaplasia characterized by cells with benign-appearing nuclei, eosinophilic cytoplasm, and solid growth pattern. Some metaplastic foci approached the muscularis mucosae, mimicking adenocarcinoma at low power magnification. Interestingly, these metaplastic foci were reactive against p16 immunohistochemical stain. Results (if a Case Study enter NA) NA Conclusion We present these three cases to add to the few previously reported. Pathologists should be aware of this finding to avoid the overdiagnosis of invasive carcinoma in the setting of nested and pseudo invasive squamous morules, especially in polyps with high grade dysplasia. In addition, squamous metaplasia could be a precursor lesion for colorectal squamous cell carcinoma.

Management of an Accidental Ingestion of a Manual Screwdriver in Implant Dentistry: A Case Report

Ingestion of foreign bodies in dentistry represents an uncommon but possible event and can be life-threatening. An 82-year-old patient presented at our attention for an implant-supported rehabilitation of the maxillary arch. During the placement of the fixed prosthesis, the manual screwdriver was swallowed by the patient. From the moment of the accident, the patient did not develop any symptoms and was monitored for the following days. The instrument was not recovered within 3 days, thus a series of consecutive abdominal X-rays were performed revealing that the screwdriver was located at the level of ileocecal valve with no signs of progression. The screwdriver was removed with colonoscopy under sedation. During this treatment, a polyp was discovered and excised revealing a tubulovillous adenoma depicting low-grade dysplasia. To prevent such accidents, screwdrivers in implant dentistry should be secured with ligatures, or replaced with longer torque control wrenches.

BİR EĞİTİM ARAŞTIRMA HASTANESİNDE ALT GASTROİNTESTİNAL SİSTEM BULGULARININ DEĞERLENDİRİLMESİ

Patients with complaints about colorectal region refer to general surgery, gastroenterology and other outpatient clinics with an increasing frequency. Rectal bleeding, abdominal pain, unexplained anemia, changes in bowel habit, occult blood positivity in stool can be a sign of serious colon disease. In this study, patients under the age of 65 who underwent AGIS endoscopy in the endoscopy unit of the Research and Application Hospital in Central Anatolia Region between 2015 and 2018 were examined. The data were reviewed retrospectively. 214 patients under the age of 65 were included in the study. Colitis in 37 (17.29%), hyperplastic polyp in 38 (17.76%), tubular adenoma in 86 (40.19%), tubular adenoma in 40 (18.69%), Adenocarcinoma was detected in 13 (6.7%) of results. Tubular adenoma, tubulovillose adenoma and adenocarcinomas were more common at the age of fifties, with colitis and hyperplastic polyps detected in the mean age of forties. Adenocarcinomas were found to be more common in female sex, unlike other results. Lower gis endoscopy has an important place in the diagnosis and treatment of colorectal cancer. In our study, in which the results of AGIS endoscopy were examined, tubular adenoma was high in individuals under 65 years of age. Keywords: Tubulovillous Adenoma, Colitis, Hyperplastic Polyp

Peutz-Jeghers syndrome: A case report

Peutz-jeghers syndrome is a rare inherited autosomal dominant disease which is characterized by mucocutaneous pigmentation and multiple polyps in the gastrointestinal tract. We report a case of 10 years old female who was referred to us from surgical department for the evaluation of brownish pigmented macules over lips, face, palms and soles. Patient was presented with recurrent abdominal pain along with vomiting and blood mixed stool for a month. Ultrasound of abdomen revealed jejuno-jejunal intussusception for which laparotomy was done during which multiple polyps were visualized. Polypectomy was done and biopsy revealed it to be tubulovillous adenoma. Patient was diagnosed as Peutz-jeghers syndrome as there were multiple polyps in the jejunum along with the characteristics mucocutaneous involvement.

Intramucosal duodenal adenocarcinoma concomitant with Saint’s triad

Duodenal tubulovillous adenomas are rare and have malignant potential. Their successful management depends on the preoperative diagnosis and adequate excision. Endoscopic mucosal resection or submucosal dissection can control superficial tumors. Adenocarcinoma of the duodenum may originate in tubular or tubulovillous adenoma, and possible diagnostic challenges occur concerning the endoscopic biopsy findings. We report a 62-year-old female with chronic epigastric burning and a bolus sensation. Upper gastrointestinal endoscopy showed a non-ampullary duodenal tumor, and the biopsy study diagnosed a tubulovillous adenoma. Further mucosectomy revealed an intramucosal adenocarcinoma in a tubulovillous adenoma with a tumor-free pedicle. Besides the intestinal neoplasms, the patient had the diagnosis of classical Saint’s triad; and the manifestations were hiatus hernia, gallbladder disorder, and colonic diverticula. The objective is to report two scarcely described conditions and comment on controversial points of view about the concomitance of Saint’s triad and malignancy. Case reports can reduce late diagnosis, enhancing the suspicion index on rare diseases.
