OCLC Number/Unique Identifier: 8667860684

Endometriosis is a common benign disease in women of reproductive age, it has been associated with an increased risk of various malignancies that is defined by certain histological criteria mainly 80% in ovary and 20% in extragonadal sites such as intestine, rectovaginal septum, abdominal wall, pleura and others; the greatest risk for colorectal cancer is women with adenomyosis or endometriosis; Several genetic alterations have been found in the risk of endometriosis associated with cancer; The symptomatology, imaging and endoscopic characteristics simulate other inflammatory and malignant lesions that make the preoperative diagnosis of extragonadal endometriosis difficult. This is a review of the knowledge about endometriosis and its potential risk of malignancy, particularly with colorectal cancer

Transcatheter Arterial Embolization for the treatment of upper gastrointestinal bleeding

Published on: 7th June, 2019

OCLC Number/Unique Identifier: 8165598100

Background: Transcatheter arterial embolization can be used for patients with recurrent bleeding from the upper gastrointestinal tract after failed endoscopic treatment. Our aim to identify the clinical and technical factors that influenced the outcome of transcatheter embolization for therapy of upper gastrointestinal bleeding after failed surgery or after failed endoscopic treatment in high risk surgical patients. Methods: We performed a prospective study to analysis of the 15 patients who underwent Transcatheter arterial embolization for nonvariceal upper gastrointestinal bleeding at Alshifa hospital from January 2015 to March 2019. The following variables were recorded: demographic data, time from bleeding start to TAE, units of packed red cells before TAE and units of packed plasma before Transcatheter arterial embolization and we analysis 30 days rebleeding rates and mortality. Results: Patients treated with Transcatheter arterial embolization (median age: 62 years, range: 14–79 years).The technical success rate of the embolization procedure was 100%. Time from bleeding start to TAE was 2.1 (1-4) days , units of packed red cells before Transcatheter arterial embolization was 12.8 (4-22) packed and units of packed plasma was 3.2 (2-5) packed. Following 30 days after embolization, 2 (13%) patients had repeated bleeding and 3 (20.0%) patients died. Conclusion: In our experience, arterial embolization is a safe and effective treatment method for upper gastrointestinal bleeding and a possible alternative to surgery for high-risk patients.

Endoscopic treatment of pancreatic diseases via Duodenal Minor Papilla: 135 cases treated by Sphincterotomy, Endoscopic Pancreatic Duct Balloon Dilation (EPDBD), and Pancreatic Stenting (EPS)

Published on: 8th July, 2019

OCLC Number/Unique Identifier: 8175469767

Treatments via the minor papilla is effective where the deep cannulation via the major papilla is impossible in such cases as [1] the Wirsung’s duct is inflammatory narrowed, bent or obstructed by impacted stones [2] pancreatic duct divisum (complete or incomplete) [3], maljunction of pancreatico-biliary union with stones [4], pancreatic stones in the Santorini’s duct. In [1,2] cases, the pancreatic juice flow via the major papilla decreases, while that of the minor papilla increases. Then the size of minor papilla and its orifice shows corresponding enlargement. This substitutional mechanism is an advantage when undertaking our new method. Since the pancreatic juice flow is maintained via the minor papilla in these cases, accurate and careful endoscopic skills are necessary to prevent pancreatitis due to the occlusion of the Santorini’s duct after this procedure. We have experienced 135 cases treated via minor papilla in these 27 years, so we would like to report about its safety and efficacy.

Addition of Simvastatin to Carvedilol and Endoscopic Variceal Ligation improves rebleeding and survival in patients with Child-Pugh A and B class but not in Child Pugh C class

Published on: 20th September, 2019

OCLC Number/Unique Identifier: 8299602911

Background: Even with current standard treatment after variceal bleeding which includes combination of nonselective b-blockers and repeated endoscopic variceal ligation, the risk of rebleeding and mortality are high. Statins exhibit an antifibrotic effect and improves HVPG. We evaluated whether addition of simvastatin to carvedilol plus EVL therapy reduces variceal rebleeds or death in patients with cirrhosis. Method: Patients with a variceal bleed 5 to 10 days before were randomly assigned to groups A [carvedilol (n = 69)] or group B [carvedilol (maximum dose - 12.5mg), and simvastatin (40mg/day) (n = 65)]. Primary end points were variceal rebleeding or death. Secondary end points were new complications of portal hypertension and serious adverse effects of drugs. Results: During a mean follow-up of 49.05 ± 25.74 weeks, composite end point i.e. rebleeding or death developed in 23 patients (33.3%) in group A and 12 patients (18.5%) in group B [HR for simvastatin = 0.512; 95% CI: 0.254 – 1.030; p = 0.06]. In subgroup analysis by excluding patients of Child C class, 18 patients (34.6%) in group A and 7 patients (13.6%) in group B developed composite end point [HR for simvastatin = 0.369; 95% CI: 0.154 – 0.887; p = 0.026]. 17.4% and 15.4% patients in group A and B developed additional secondary complication [HR = 0.86; 95% CI: 0.345-2.161; p = 0.75). No simvastatin induced significant adverse effects were found. Conclusion: Addition of simvastatin to carvedilol and EVL may reduce the rebleeding and death in patients with less advance liver disease.

Heterotopic Gastric Mucosa of the Proximal Esophagus: An Under recognized Entity

Published on: 5th February, 2020

OCLC Number/Unique Identifier: 8534144758

Heterotopic gastric mucosa (HGM) is an islet of gastric mucosa within the esophageal mucosa. These lesions can sit throughout the digestive tract and rarely in the upper third of the esophagus. The pathophysiology of HGM remains poorly understood. Our study aims to estimate the prevalence of HGM, clinical signs, endoscopic, microscopic aspects and different epidemiological factors associated. All patients from a single endoscopy center with HGM of the upper third of the esophagus were included over a 5-month evaluation period. All lesions seen in endoscopy were confirmed by histological analysis. The prevalence was 1.3% with a clear male predominance. 80% of patients were symptomatic and received medical treatment, clinical evolution was good. No case of dysplasia was identified and no complication was observed. Due to insufficient data in the evolutionary literature, the management of HGM remains debated and could resemble that of Barett’s esophagus for monitoring and therapeutic management, particularly in the event of symptoms or dysplasia.

Laparoscopic anterior transgastric cystogastrostomy for the treatment of pancreatic pseudocysts

Published on: 6th April, 2020

OCLC Number/Unique Identifier: 9272371062

Introduction: Pancreatic pseudocysts (PPs) are mostly delayed complications of acute or chronic pancreatitis and trauma. Pancreatic pseudocysts are usually managed by supportive medical treatment without surgical procedure. All the surgical interventions (percutaneous, endoscopic or surgical approaches) are based on the location, size, symptoms, complications of the pancreatic pseudocyst and medical condition of the patients. Recently, laparoscopic cystogastrostomy has become most appropriate approach especially for retrogastric pancreatic pseudocysts. In this study, we would like to report results of laparoscopic anterior transgastric cystogastrostomy by using linear articulated endo GIA stapler (Covidien medium thick purple) and versa-lifter (versa lifter®, laparoscopic retractor, manufactured by protomedlabs, France) in 14 pancreatic pseudocysts patients. Methods: We retrospectively analyzed data of patients with pancreatic pseudocysts treated by laparoscopic anterior transgastric cystogastrostomy from September 2010 to October 2014. All of the patients were controlled for the recurrence of pancreatic pseudocysts in February 2017. Results: 14 patients with pancreatic pseudocysts were managed by laparoscopic anterior transgastric cysto-gastrostomy. Conversion was performed in only one patient (7%). There were no symptoms and signs of recurrence of pancreatic pseudocyst during on average 43.6 months follow up time. Conclusion: Laparoscopic cystogastrostomy by using articulated linear endo-GIA stapler and versa-lifter is a safe and effective method for management of appropriate retro-gastric pancreatic pseudocysts.

Bouveret Syndrome in an Elderly Female

Published on: 3rd January, 2017

OCLC Number/Unique Identifier: 7317627575

Introduction: A gastric outlet obstruction secondary to a gallstone ileus is known as Bouveret syndrome. Herein we present a case of an elderly woman with an impacted gallstone in duodenum and discuss its’ management. Patient description: A 96-year-old woman was admitted to our department due to a gastric outlet obstruction. Initial gastroscopy revealed a gastric bezoar. An attempt for its extraction failed. She underwent a laparotomy in which a cholecystoduodenal fistula and a large impacted stone were found. Separation of the fistula, including closure of the duodenum side, cholecystectomy and removal of the obstructing gallstone were performed. Additional stones were found and retrieved during common bile duct (CBD) exploration. Surgery was finalized by duodenoplasty, closure and T-tube drainage of the CBD. Post-operative course was prolonged and uneventful. Discussion and Conclusions: Bouveret syndrome is a rare cause of gastric outlet obstructions. In this case, unsuccessful endoscopic treatment necessitated surgery for removal of impacted gallstone in the duodenum.

Dieulafoy’s Lesion related massive Intraoperative Gastrointestinal Bleeding during single Anastomosis Gastric Bypass necessitating total Gastrectomy: A Case Report

Published on: 15th September, 2017

OCLC Number/Unique Identifier: 7317595611

Introduction: Immediate postoperative gastrointestinal bleeding following bariatric bypass surgery is a major complication, and usually results from staple line hemorrhage or conventional gastro-esophageal causes. Dieulafoy`s lesion is a rare cause of gastrointestinal bleeding and is usually managed by endoscopic means. Herein we present a case of massive intraoperative bleeding resulting from gastric Dieulafoy`s lesion single anastomosis gastric bypass surgery necessitating resection of the gastric pouch. This is the first description of this complication, and the difference of such a lesion from the sporadic ones is discussed. Discussion: Gastric bypass surgery is an effective procedure for morbid obesity. The approach we have adopted for massive upper GI hemorrhage in the immediate postoperative period should be distinguished from delayed bleeding after gastric bypass. In these latter cases, marginal ulceration is more common than bleeding from the remnant gastric pouch. It is also likely that bleeding from a Dieulafoy`s lesion following gastric bypass surgery represents a different disease compared to other Dieulafoy`s cases. Conclusion: This is the first description of an intraoperative Dieulafoy`s lesion bleeding during the conduct of a single anastomosis gastric bypass procedure which required gastric pouch resection. Such a lesion differs from sporadic Dieulafoy`s cases, and must be considered in every case of intraoperative bleeding during gastric bypass.

Safety and effectiveness of laparoscopic management in 210 patients with erosion of adjustable Gastric banding

Published on: 21st November, 2017

OCLC Number/Unique Identifier: 7317595343

Background: The band erosion (BE) is defined as the partial or complete movement towards the lumen of the stomach, is also known as migration, gastric incorporation and gastric inclusion. The presentation of this complication involves failure of bariatric procedures being ineffective and consequently requires the removal of the laparoscopic adjustable gastric banding (LAGB), usually through laparoscopic surgery. The objective of this study is to describe the clinical presentation, diagnostic methods, surgical procedure, postoperative evolution in the integral treatment of BE. Material and Methods: We captured the data of patients with BE since January 2010 to October 2017. Database included the year of patient care, age, and sex, BMI before band placement, percentage of excess weight loss, number of device adjustments, clinical data and surgical procedure performed for resolution. Results: A total 379 LAGB complications were diagnosed in our Institution; 210 patients with BE were diagnosed and treated, the average age was 39 years; range from 19 to 66 years, sex was 178 women and 32 men. The diagnosis was endoscopic in the 210 patients (100%). The surgical procedure to solve the problem was: to remove the LAGB, the fistulous orifice was closed and patch of omentum. The hospital stay was 3-5 days. The motility was zero. Complications were minor in 3% of the 210 patients (fever, atelectasis, wound infection). One patient was re-operated for evolving to residual abscess. Conclusions: The BE is a serious failure in bariatric surgery. The resolution in this group of patients was to remove the band, direct closure of the fistulous orifice with patch of omentum. The surgical technique that was performed in this complication is safe, effective and easily reproducible.

Leakage after sleeve gastrectomy: Endoscopic stenting VS surgical intervention

Published on: 24th July, 2020

OCLC Number/Unique Identifier: 8639114108

Background: Laparoscopic sleeve gastrectomy (LSG) is becoming more popular in the treatment of obesity. LSG is safe with a low morbidity. The complications rarely result in morbidity and even mortality. Leaks are the major complication associated with LSG with a reported prevalence between 1.9% and 2.4%. Objective: To compare surgical intervention and endoscopic stenting for treatment of gastric leakage after sleeve gastrectomy. Patients and method: Our study included 30 patients presented with post sleeve leaks discovered by routine postoperative imaging or during the follow up period. Patients were recruited from October 6th university hospital during the period from August 2017 to August 2019. Patients were divided to the following groups: 1) Endoscopy group: This included 15 patients with post sleeve leakage undergoing endoscopic stent insertion. 2) Surgery group: which included 15 patients with post sleeve leak age undergoing surgical management. This division was random. Results: Our study showed that Endoscopic stenting for management of post sleeve gastrectomy leakage is an effective method with lower morbidity and shorter post-operative hospital stay than surgical management. Some patients may be good candidates for early surgical intervention in type 1 leakage if managed early before dissemination of leakage and before tissues become friable. Complications of stents include stent migration (26%), stent related ulcer (13%) and stricture (13%). while the surgical intervention carries more complications (DVT, chest infection, wound infection and stricture) and longer postoperative hospital stay. Conclusion: endoscopic management of post-sleeve gastrectomy leakage with stenting is recommended because it successfully manages the leaks and avoids invasive procedures with less risk, with shorter hospital stay and early return of function.

Clinical, histopathological and surgical evaluations of persistent oropharyngeal membrane case in a calf

Published on: 5th August, 2019

OCLC Number/Unique Identifier: 8198752192

A male, 4 days old and 20 kg Simmental calf was evaluated for regurgitation and hyper salivation since birth. The mother became pregnant by artificial insemination and the pregnancy was the second of the mother. A membrane closed the pharynx and a diverticulum on dorsal of this membrane was seen during oropharyngeal examination through inspection. Membrane was also viewed by endoscopy under general anaesthesia. Larynx and oesophagus were imaged by bronchoscopy through the back side of the membrane. After these applications, it was decided that soft palate adhered firmly to the root of tongue causing congenital atresia. Surgical treatment of oropharyngeal membrane was carried out under general anaesthesia. Firstly, tracheotomy was performed for to ease breathing and membrane removed by electrocautery application. Intensive fluid accumulation and oedema formation at the incision area were detected by endoscopic examination following operation and the calf had severe dyspnoea two days after operation and died due to respiratory insufficiency. At necropsy, severe inflammatory reaction, laryngeal oedema and intensive salivation at the surgical side was determined. Direct imaging techniques should be used to determine in the closed oropharyngeal lumen. Moreover, nasopharyngoscopy should be considered to image larynx and oesophageal way. Present case is the first report with concern to pharyngeal membrane formation together with direct imaging and surgical procedures. Therefore, it was considered that this case report could be useful for colleagues and literatures.

Persistent hydronephrosis after pyeloplasty: Is it a true obstruction? The role of endourology

Published on: 13th April, 2020

OCLC Number/Unique Identifier: 8582316817

Introduction: Anderson-Hynes pyeloplasty remains the gold standard in the treatment of ureteropelvic junction obstruction. The diagnostic criteria for defining the failure of pyeloplasty are not well-defined or even arbitrary. Likewise, the ideal treatment of persistent hydronephrosis after pyeloplasty is not well established. We tested an innovative endourological procedure, which simultaneously allows a diagnostic definition of failure and treatment when necessary. Materials and methods: The endourological procedure was applied prospectively to 13 cases from 2006 to 2015. The mean hydronephrosis was 3 cm and all the patients showed an obstructive pattern at scintigraphie. Of these, only 2 patients had symptoms. The procedure consisted in the endoscopic calibration of the pyeloureteral junction. In case of confirmed persistent stenosis, the procedure continued with the high pressure dilation of the junction. The calibration/dilation procedure was carried out with a balloon catheter, previously used for high pressure dilation in the obstructive megaureter. In all patients, a ureteral stent was positioned for 6 - 8 weeks. The patients were then followed up using ultrasound and renoscintigraphie. Results: According to the endoscopic balloon procedure, anastomosic stenosis was confirmed in 3 cases, treated with high pressure dilation during the same procedure. In 10 cases no stenosis was found and we followed-up these patients with periodic ultrasound and scintigraphie. Conclusion: The calibration/dilation of the pyeloureteral junction represents in our opinion a useful diagnostic and therapeutic tool that allows to limit the repetition of open surgery only to symptomatic cases and those non-responders to endoscopic treatment.

Outpatient operative hysteroscopy: evaluation of patient satisfaction and acceptance

Published on: 18th January, 2022

OCLC Number/Unique Identifier: 9396216754

Aims: To examine patient satisfaction of an outpatient operative hysteroscopy performed by both doctors and nurse hysteroscopists. Secondly, compare satisfaction, complications, and failure rate of these procedures performed by doctors and nurse hysteroscopists.Methods: In this retrospective study, the charts of 80 women who attended the service over one year were examined. Women were included if either an endometrial polyp or submucosal leiomyoma required removal using an endoscopic morcellator. All women had signed a consent form for the procedure. Results: In total 67/80 (84%) patients were satisfied with the service. Nurse hysteroscopists completed most procedures 59/80 (74%). Satisfaction ratings were not recorded for 13/80 (16%) consultations, completed by doctors. There was no difference in satisfaction and complication rates between doctors and nurse hysteroscopists. A total of five patients required repeat endoscopic morcellation, three completed by doctors and two completed by nurse hysteroscopists. For this group, satisfaction and complication ratings did not change.Conclusion: High patient satisfaction and low complication rates were found. Nurse hysteroscopists performed more procedures, providing a safe and useful service. Few patients required repeat morcellation procedures.

Risk factors for esophageal strictures in children and adolescents with eosinophilic esophagitis

Published on: 27th October, 2022

Studies in children with eosinophilic esophagitis (EoE) have reported esophageal strictures but none have examined risk factors associated with strictures. Aim: To assess risk factors associated with strictures in children with EoE. Methods: In this retrospective study, children with EoE seen over 20 years were separated into two groups; with and without strictures. Physical features, CBC, endoscopic findings, and biopsy of the distal and mid-esophagus were captured. Statistical significance with p - value and multivariate logistic regression was done. Results: Total patients 222 and 20 (9.1%) had strictures. Mean age of stricture patients 12.7 years (range 7-18) and non-stricture 9.3 years (range 1-17) (p = 0.006). Among stricture patients following were prevalent and significant; dysphagia (stricture 100% vs. non-stricture 41.6%, p = 0.0005) and food impaction (70.04% vs. 4%, p = 0.0005); EGD: rings and exudates were strongly associated with stricture, 45.0% vs. 4.5%, p = 0.0005 and 60% vs. 30.7%, p = 0.008, respectively. Abdominal pain was lower in the stricture group (5% vs. 31.2%, p = 0.017). Eosinophil counts were numerically more in the stricture group but not significant. Multivariate logistic regression confirmed that strictures are likely to occur among patients with dysphagia (p = 0.02, OR = 11.7, 95% LCL 2.0) and food impaction (p = 0.0001, OR = 80.9, 95% LCL 15.4), respectively, adjusted for age and gender. Conclusion: EoE children with dysphagia or food impaction have a higher chance of having an esophageal stricture. These EoE children 12 years or over with exudates or rings on endoscopy, should be treated and carefully monitored, to reduce the risk of stricture formation.

Transcanal Endoscopic Excision of Glomus Tympanicum in can tho Ent Hospital: Three Cases Report

Published on: 13th July, 2023

Glomus tympanicum (GT) is a highly vascular, benign, and slow-growing tumor of the middle ear. It can be confused with other common ear diseases such as acute middle ear infection, otitis media with effusion, ear trauma… It is accurately diagnosed by history and endoscopy. CT scan showing: the presence of eroding jugular bulb is the most important thing to distinguish glomus tympanicum and glomus jugulare and assess the extension of the tumor to make good surgical planning. We present here the three cases in Can Tho ENT hospital: where total excisions were achieved trans-canal endoscopically without embolization. These procedures were safe, quick, and effective due to the better visualization of the surgical field with the endoscope.

Bispectral Index Monitoring: Ability to Detect Deep Sedation during Endoscopy

Published on: 24th October, 2023

Background: Clinical practice guidelines recommend monitoring the depth of anesthesia during endoscopic examination of the gastrointestinal tract using sedation scales, despite their subjective nature, while the use of the bispectral index, an objective measure, during sedation, remains controversial. The main objective of this study was to assess the ability of bispectral index monitoring to characterize the depth of anesthesia during endoscopy.Methods: We conducted a cross-sectional study to assess the performance of the bispectral index using data from a multicentre clinical trial with 180 patients undergoing scheduled colonoscopies. Sedation was monitored using the bispectral index and Ramsay Sedation Scale. Data on sedation were recorded at five-time points (t1 to t5) during the colonoscopy.Results: Bispectral values were significantly associated with Ramsay scores (rho, -0.73; p < 0.0001). In regression analysis, each unit increase in bispectral value was associated with a reduction in the risk of a high Ramsay score (> 3) at all points (OR 0.922; 95% CI: 0.865–0.979; p < 0.0001 at t1). Receiver operating characteristic curve analysis found areas under the curve of 0.8272 for a bispectral index cut-off for deep sedation of 69.76 (sensitivity, 95.35%; negative predictive value, 97.53%) when reaching the colic flexure (t2) and 0.8399 for a cut-off of 69.29 (sensitivity, 96.15%; negative predictive value, 98.81%) at the end of the colonoscopy (t5).Conclusion: Bispectral index monitoring enables objective real-time reliable assessment of sedation. It enables easy continuous monitoring with a very good performance for detecting deep sedation and correlates with a clinical scale routinely used in endoscopic procedures.

Endoscopic Endonasal total Removal of a Suprasellar, Preinfundibular Retro Chiasmatic Craniopharyngioma: A Surgical Case Report

Published on: 26th March, 2024

Craniopharyngiomas are benign tumors (WHO Grade I), seen in children and adults. Because of their location, they can require challenging clinical and surgical management. In fact, often, because of the presence of calcifications, of a capsule very strongly adherent to neurovascular structures, of the relationship with hypophysis, pituitary stalk, chiasm, carotids, the circle of Willis, basilar artery, and third ventricle, risk of mortality and morbidity is still mandatory. Various surgical techniques have been proposed: transcranial, transsphenoidal, and supraorbital approaches for surgical resection and treatment of craniopharyngiomas. Still, there is no common consent, but often the endonasal transsphenoidal extended procedures are considered the gold standard in many cases. We present a surgical technique of a case of complete surgical removal of an infundibular and retro chiasmatic craniopharyngioma, via an endoscopic endonasal transphenoidal transplanum approach.

Complications of External Otitis in Horses

Published on: 21st May, 2024

The physiological removal of foreign bodies in the horse’s external ear canal is best achieved by head-shaking. However, external otitis in the horse induces moderate to severe pain: therefore, the horse does not shake his head. The causes of external otitis are dust, water in the external ear canal, keratin, and ceruminous debris. The clinical symptoms are ear discharge, skittishness, facial nerve paresis, and/or head tilt. After the horse has been sedated, the most important diagnostic procedure is the endoscopy of the cartilaginous and osseous part of the external ear canal, including the evaluation of the transparency of the tympanic membrane. The clinical complications of external otitis are hearing loss, facial nerve paresis, head tilt, hypertrophy of the tympanostylohyoideum, and corneal ulcers. The most important treatment is soaking up the exudate in the osseous part of the external ear canal using small cotton balls which are held by the foreign body forceps of the endoscope. Based on the results of the culture of exudate and the antibiogram, an antibacterial drug must be administered orally for 3 to 4 weeks. At this time, an endoscopy of the external ear canals and guttural pouches also has to be done. Based on the outcome of the endoscopy, endoscopic and clinical investigations have to be performed six months later as well. Only 7/19 horses had a normal osseous part of the external ear canal with a transparent tympanic membrane, including normal hearing measured by the brainstem auditory-evoked response after one month of treatment.
