Obesity is a major health problem in western countries, and sleeve gastrectomy has proven its effectiveness on weight loss and improvement of comorbidities related to obesity. The main complication is the occurrence of upper fistula (2%), and may be responsible of several deaths. There is no consensus on medical, radiological and surgical management of fistula. It depends on the resources of each center and is based on a low level evidence The inconstant efficacy of the endoscopic treatment by closing fistula (digestive stents, clips, glue) motivates a new endoscopic approach. It consists of an internal drainage of the collection by using double pigtail stents through the fistulous orifice.

Present study investigated the efficacy of injection of freshly collected autologous adipose tissue into perianal fistulas in patients with Crohn's disease. Adipose tissue collected by liposuction was injected into the perianal fistulas. Primary objective was complete clinical healing six months after treatment. Secondary objectives were reduced or ceased fistula secretion and complications to the treatment.

Perianal fistula(PF) is one of the most frequent disease in anorectal disease.The incidence of PF is 8,6 -10 / 100 000 . The first surgical treatment is defined by Hippocrates in PF .This surgical treatment which found by Hippocrates , involves seton insertion into the tract of fistula . Today most of surgeon still use the same technic but PF is really hard disease to treat. Recurrence rate of PF is really high and there are lots of complication about this disease. The most scary complication during the surgery or postoperatively is anal disfunction. ın PF surgical technics involves ;fistulectomy (coring out), lay open (fistulotomy), Ligation of Intersphincteric Fistula Tract, advancement flap and laser ablation of the fistula tract . The popularity of laser ablation of the fistula tract is increasing day by day.This surgical procedure is applied with the laser device which use in varicose vain ablation in vascular surgery.In this study the investigator are trying to find out the effect of steam ablation in PF on rats.

After removing large polyps from the gastrointestinal tract, gastroenterologists close the new defect with devices to prevent complications like bleeding or the development of a leak. Commonly, this is done with a device called Overstitch, which allows the gastroenterologist to stitch the defect with an endoscope. A new device called X-tack has been developed to simplify endoscopic stitching. In this study, the new X-tack device will be compared to Overstitch when closing defects in the gastrointestinal tract. The two devices will be compared to see how long it takes to close a defect, as well as if there are any differences in complications like bleeding or infection.

This study included patients who were admitted to investigators' center to do laparoscopic sleeve gastrectomy and complicated by gastro-cutaneous fistula . Cases were collected in the period from December 2019 to march 2021. The study was approved by the research and Ethics committee of investigators' University .a written informed consent was obtained from all participating patients after explaining to them all the study procedures with its benefits and hazards. the work has been carried out in accordance with the code of ethics of the world medical association ( Declaration of Helsinki ) for studies involving humans .the sample size was calculated using open Epi program using the following data ; confidence interval 95% , power of test 80% , ratio of unexposed/exposed 1, percent of patients with successful management of refractory gastro-cutaneous fistula by surgical intervention 50% and those with successful management by endoscopy 99% , odds ratio 99%, and risk ratio 2 , so the calculated sample size equal 30 patients divided into two equal groups. Group (1) included 15 patients managed by surgical intervention , group (2) included 15 patients managed by endoscopic intervention.

Urethrocutaneous fistulae (UCF) represent one of the most frequent causes of morbidity after urethroplasty. Hypospadias can be repaired using different surgical techniques, but regardless of technique, the incidence of UCF ranges between 10% and 40%. The surgical repair of UCF remains the treatment of choice, even if some patients need further operations because of recurrences. The cyanoacrylates have been used as skin suture substitutes, and some evidence suggests a beneficial effect when these adhesives are used as an adjuvant in the management of UCF.

Primary Objective: To evaluate the clinical efficacy of Naturetti (capsules) , considering the following criteria: Evacuation frequency during the treatment and follow-up period Consistency of stools during the treatment and follow-up period Global evaluation, regarding increase in frequency of evacuation and shape of stools. Secondary Objective: Number of days without evacuation Proportion of evacuation with pain Proportion of evacuation with strain Proportion of evacuation with incomplete sensation Proportion of blocked stools Proportion of manual maneuvers to facilitate defecation Proportion of subjects that adhere to the diet recommended Proportion of the patients who have to use rescue medication Level of constipation improvement, according to the patient evaluation To evaluate clinical tolerability of the study medication by the continuous use To evaluate the occurrence of adverse events related to the study drug To identify any drug interaction.
