Project description:IntroductionEndoscopic full-thickness resection (eFTR) using the full-thickness resection device (FTRD®) is a novel minimally invasive procedure that allows the resection of various lesions in the gastrointestinal tract including the colorectum. Real-world data outside of published studies are limited. The aim of this study was a detailed analysis of the outcomes of colonoscopic eFTR in different hospitals from different care levels in correlation with the number of endoscopists performing eFTR.Material and methodsIn this case series, the data of all patients who underwent eFTR between November 2014 and June 2019 (performed by a total of 22 endoscopists) in 7 hospitals were analyzed retrospectively regarding rates of technical success, R0 resection, and procedure-related complications.ResultsColonoscopic eFTR was performed in 229 patients (64.6% men; average age 69.3 ± 10.3 years) mainly on the basis of the following indication: 69.9% difficult adenomas, 21.0% gastrointestinal adenocarcinomas, and 7.9% subepithelial tumors. The average size of the lesions was 16.3 mm. Technical success rate of eFTR was achieved in 83.8% (binominal confidence interval 78.4-88.4%). Overall, histologically complete resection (R0) was achieved in 77.2% (CI 69.8-83.6%) while histologically proven full-wall excidate was confirmed in 90.0% (CI 85.1-93.7%). Of the resectates obtained (n = 210), 190 were resected en bloc (90.5%). We did not observe a clear improvement of technical success and R0 resection rate over time by the performing endoscopists. Altogether, procedure-related complications were observed in 17.5% (mostly moderate) including 2 cases of acute gangrenous appendicitis requiring operation.DiscussionIn this pooled analysis, eFTR represents a feasible, effective, and safe minimally invasive endoscopic technique.

Project description:BackgroundIn severe forms of endometriosis, the colon or rectum may be involved. This study evaluated the functional results and long-term outcome after laparoscopic colonic resection for endometriosis.Patients and methodsQuestionnaire survey with 24 women who had experienced typical symptoms, including pelvic pain, infertility, and endometriotic lesions in the bowel and undergone laparoscopic surgery, including low anterior resection, from 2009 to 2012, was conducted.ResultsInformation about the postoperative outcome was obtained from 22 women and was analyzed statistically. Twenty-one had undergone low anterior resection; one patient required a primary Hartmann procedure due to a rectovaginal fistula. The conversion rate was 4.5%. Major complications occurred in one patient, including an anastomotic leakage, and a Hartmann procedure was carried out subsequently in this patient. The symptoms of pain during defecation, pelvic pain, dyspareunia, dysmenorrhea, and hematochezia showed clear improvement one year after the operation and at the time of the questionnaire.ConclusionLaparoscopic low anterior resection for deeply infiltrative endometriosis is technically demanding but feasible and safe, and it improves the clinical symptoms of endometriosis in the bowel.

Project description:Urinary endometriosis is a rare condition accounting for 1-5.5% of the extragenital endometriosis locations. The diagnosis takes long time during which patient misdiagnosed as urinary tract infection or interstitial cystitis. A 25-year-old married woman presented with cyclical pain last for ten days every month for six months prior to diagnosis. There was no history of hematuria. Had three times caesarian section. Endometrial mass on posterior wall of bladder about 3 × 2 cm treated by transurethral resection. Chocolate appearance of blood during transurethral resection is highly suggestive of diagnosis of bladder endometriosis.

Project description:There is indirect evidence to suggest that 80% of colorectal cancers (CRC) develop from adenomatous polyps and that, on average, it takes 10 years for a small polyp to transform into invasive CRC. In multiple cohort studies, colonoscopic polypectomy has been shown to significantly reduce the expected incidence of CRC by 76% to 90%. Colonoscopic polypectomy is performed frequently in primary outpatient clinics and secondary and tertiary medical centers in Korea. However, there are no evidence-based, procedural guidelines for the appropriate performance of this procedure, including the technical aspects. For the guideline presented here, PubMed, Medline, and Cochrane Library literature searches were performed. When little or no data from well-designed prospective trials were available, an emphasis was placed on the results from large series and reports from recognized experts. Thus, these guidelines for colonoscopic polypectomy are based on a critical review of the available data as well as expert consensus. Further controlled clinical studies are needed to clarify aspects of this statement, and revision may be necessary as new data become available. This guideline is intended to be an educational device to provide information that may assist endoscopists in providing care to patients. This guideline is not a rule and should not be construed as a legal standard of care or as encouraging, advocating, requiring, or discouraging any particular treatment. Clinical decisions for any particular case involve a complex analysis of the patient's condition and the available courses of action.

Project description:BackgroundAcute appendicitis is a surgical emergency in which the appendix is surgically removed to prevent peritonitis due to perforation of the appendix. Depending on age and gender, up to 17% of removed appendices do not show the histopathological changes pathognomonic for acute appendicitis and are called 'pseudo-appendicitis'. Intestinal spirochaetes have been reported in up to 12.3% of these non-inflamed appendices obtained from adults. Although children carry the highest risk for acute appendicitis, not much is known on the prevalence of intestinal spirochaetes in children. The aim of this study was to determine whether there is an association between pseudo-appendicitis and appendiceal spirochaetosis in children.MethodsArchival appendix specimens from paediatric patients (less than 18 years old) were obtained from two Dutch hospitals (acute appendicitis, n = 63; pseudo-appendicitis, n = 55; control appendices, n = 33) and microscopically analysed by H&E staining and spirochaete-specific immunohistochemistry and Brachyspira species specific real-time PCR.ResultsFive out of 142 appendices were found to be positive, all in male patients: one in the acute appendicitis group, two in the pseudo-appendicitis group and two in the control group.ConclusionThe results obtained do not provide evidence for a role of Brachyspira species infection in the aetiology of acute appendicitis in children.

Project description:Endometriosis is a gynecological pathology that affects between 6 and 15% of women of childbearing age. One of the manifestations is intestinal deep infiltrating endometriosis. This condition may force patients to resort to surgical treatment, often ending in resection. The level of blood perfusion at the anastomosis is crucial for its outcome, for this reason, indocyanine green (ICG), a fluorochrome that green stains the structures where it is present, is injected during surgery. This study proposes a novel method based on deep learning algorithms for quantifying the level of blood perfusion in anastomosis. Firstly, with a deep learning algorithm based on the U-Net, models capable of automatically segmenting the intestine from the surgical videos were generated. Secondly, blood perfusion level, from the already segmented video frames, was quantified. The frames were characterized using textures, precisely nine first- and second-order statistics, and then two experiments were carried out. In the first experiment, the differences in the perfusion between the two-anastomosis parts were determined, and in the second, it was verified that the ICG variation could be captured through the textures. The best model when segmenting has an accuracy of 0.92 and a dice coefficient of 0.96. It is concluded that segmentation of the bowel using the U-Net was successful, and the textures are appropriate descriptors for characterization of the blood perfusion in the images where ICG is present. This might help to predict whether postoperative complications will occur during surgery, enabling clinicians to act on this information.

Project description:Introduction:Large resections may be necessary in cytoreductive surgery for endometriosis, which present risk of urinary and bowel complications. Presentation of Case. A 29-year-old woman underwent multidisciplinary laparoscopy for endometriosis in a private practice setting for acyclic pelvic pain and cyclic abdominal distension with changes in bowel habits and frequent sensation of incomplete defecation. After surgery, urodynamics remained normal and bowel function improved subjectively and objectively per dynamic magnetic resonance defecography (DMRD). The five-month follow-up found improvements in pain scores, bowel function, and health-related quality of life (assessed by the full versions of the Short Form 36 and Endometriosis Health Profile 30 scales). Discussion. Animus may contribute to the bowel symptoms in women with endometriosis. DMRD provides additional objective parameters for comparing pre- and postoperative functions. Conclusion:A nerve-sparing segmental rectosigmoidectomy for endometriosis carefully executed by a multidisciplinary team can preserve the function of different pelvic organs.

Project description:Background/aimEndometriosis infiltrating the rectum often requires resection with a protecting stoma. A ghost ileostomy (GI) is an alternative to prevent the psychological burden for the young women affected. The present study evaluated the safety and cost-effectiveness of the ghost ileostomy (GI) procedure in a group of patients after rectal resection for deep infiltrating endometriosis.Patients and methodsThe prospective controlled interventional trial was conducted in 54 consecutive patients with deep infiltrating endometriosis of the rectum. GI was considered after ultra-low resection with primary anastomosis, previous colorectal anastomosis, or pelvic redo surgery. Loop ileostomy (LI) was performed after simultaneous colpotomy with suture, only. Operating time, morbidity according to the Clavien-Dindo classification (CDC), duration of hospital stay, and patient satisfaction were obtained. Individual costs were estimated for the endometriosis procedure with or without a GI or LI, including stoma supply and closure expenses.ResultsOf the 54 patients, 27 received GI (50%), whereas 4 underwent LI (7%). The remaining 23 patients received no outlet (NO). The complication rate did not differ among the GI, LI, and NO groups. Two cases were re-operated and required a diverting stoma, one in the GI and the NO group each. The additional healthcare expenses for each patient receiving a LI averaged 6,000 €. The patients were very satisfied with the option of a GI.ConclusionGI is a cost-effective and safe alternative to LI after rectal resection for deep infiltrating endometriosis in cases where it is required. The individual costs per patient were reduced substantially, with a cumulative savings of 160,000 € in healthcare expenditure. Additionally, the method clearly lowers the psychological burden on the young women concerned.

Project description:Approximately 15% of colorectal cancer (CRC) cases exhibit microsatellite instability (MSI), which appears to be associated with unique biological behavior. The present study presents a case of appendiceal carcinoma associated with MSI that responded well to adjuvant chemotherapy. Clinical, pathological and immunohistochemical (IHC) characteristics have been described. The 60-year-old male patient had suffered from recurrent lower abdominal pain associated with abdominal distention for 6 months; then, following an acute attack, he was subjected to laparoscopic appendectomy. The histopathological examination revealed moderately differentiated appendiceal adenocarcinoma with mucinous areas, without lymphovascular or perineural invasion. The IHC examination was positive for keratin-20 and caudal type homeobox 2, and negative for MutL Homolog 1, MutS Homolog (MSH) 2 and MSH-6. A postoperative colonoscopy revealed diverticulosis, without the presence of polyps or tumors. However, an abdominal axial computerized tomography scan revealed thickening of the distal portion of the appendix, increased density of the greater omentum, and metastases to the liver capsule, spleen and peritoneum. The treatment of choice was right hemicolectomy with peritoneal debulking, followed by 10 cycles of chemotherapy with 5-fluorouracil, leucovorin and oxaliplatin (FOLFOX regimen). After 5 years of follow-up, the patient remains in good condition, without clinical or radiological signs of recurrence. The good response to chemotherapy corresponds with the observations made in other colon cancers with MSI. Therefore, testing for MSI in appendiceal carcinomas may provide useful information on prognosis and predict response to chemotherapy.

Project description:ObjectiveIn this study, we utilized gonadotropin-releasing hormone analogue-modified indocyanine green (GnRHa-ICG) to improve the accuracy of intraoperative recognition and resection of endometriotic lesions.MethodsGonadotropin-releasing hormone receptor (GnRHR) expression was detected in endometriosis tissues and cell lines via immunohistochemistry and western blotting. The in vitro binding capacities of GnRHa, GnRHa-ICG, and ICG were determined using fluorescence microscopy and flow cytometry. In vivo imaging was performed in mouse models of endometriosis using a near-infrared fluorescence (NIRF) imaging system and fluorescence navigation system. The ex vivo binding capacity was determined using confocal fluorescence microscopy.ResultsGnRHa-ICG exhibited a significantly stronger binding capacity to endometriotic cells and tissues than ICG. In mice with endometriosis, GnRHa-ICG specifically imaged endometriotic tissues (EMTs) after intraperitoneal administration, whereas ICG exhibited signals in the intestine. GnRHa-ICG showed the highest fluorescence signals in the EMTs at 2 h and a good signal-to-noise ratio at 48 h postadministration. Compared with traditional surgery under white light, targeted NIRF imaging-guided surgery completely resected endometriotic lesions with a sensitivity of 97.3% and specificity of 77.8%. No obvious toxicity was observed in routine blood tests, serum biochemicals, or histopathology in mice.ConclusionsGnRHa-ICG specifically recognized and localized endometriotic lesions and guided complete resection of lesions with high accuracy.
