BACKGROUND

Gastric outlet obstruction (GOO) results from intrinsic and extrinsic obstruction of the pyloric channel or the duodenum. Here we present a rare case of GOO attributed to dense adhesions between the gallbladder and duodenum secondary to chronic cholecystitis with choledococystoduodenal fistula formation. Previous reports identified elderly females with comorbidities as a predisposing factor; however, our patient was an immunocompetent adult male.

A 43-year-old male with no comorbidities consulted for recurrent epigastric pain, vomiting and weight loss. On contrast enhanced abdominal CT scan, a lamellated cholelithiasis with pneumobilia and an irregular thickening at the proximal duodenum with subsequent GOO was identified. A choledococystoduodenal fistula was considered. Exploratory laparotomy revealed extensive fibrosis and cholecystitis with dense adhesions to surrounding structures. Dissection revealed a gallstone impacted in and adherent to the wall of the gallbladder and a fistula opening into the duodenum. However, there was no definite evidence of impacted gallstone in the duodenum. The dense adhesions secondary to chronic cholecystitis caused duodenal narrowing and subsequent GOO. He eventually underwent antrectomy, pancreatic sparing, total duodenectomy, cholecystectomy, with loop gastrojejunostomy, cholecystojejunostomy and pancreaticojejunostomy. Biopsy specimens taken were negative for malignancy. He was discharged subsequently. However, he was readmitted after five months due to acute abdomen secondary to small bowel rupture, likely from a marginal ulcer.

This case highlights that preoperative and intraoperative differential diagnosis of GOO is a challenge. Chronic calculous cholecystitis through severe inflammation can present as a rare cause of GOO. Optimal treasaFtment plan should take into consideration the underlying etiology of the GOO.

Open abdomen therapy is an effective treatment to deal with severe abdominal infections, abdominal hypertension and other critical abdominal diseases. However, this therapy is difficult to implement and has many uncertainties in the timing, manners, and follow-up treatment, which leads to the fact that open abdomen therapy is not very accessible and standardized in medical systems of China. This consensus aims to provide guiding principles for indications and implementation of open abdomen, classification methods of open abdomen wounds, technologies for abdominal closure, and management of enteroatmospheric fistula, so as to improve the accessibility and success rate of open abdomen in China.

: Objective: To investigate the efficacy of fistula stent made by 3D printing technique in the treatment of enteroatmospheric fistula. Methods: A descriptive case series study was carried out. INCLUSION CRITERIA: (1) patients with open abdomen; (2) patients with enteroatmospheric fistula. EXCLUSION CRITERIA: (1) patient with two or more fistulas; (2) distal obstruction; (3) bowel stenosis over 50%. According to above criteria, 17 EAF patients admitted to the General Surgery Department of Jinling Hospital from June 2019 to January 2020 were retrospectively included in study. Based on the intestinal radiography, CT reconstruction and finger exploration, the size of fistula, the diameter of the intestinal tube and the angle of the intestinal lumen around the fistula were assessed. The 3D printing fistula stent was designed and established based on estimated data, and then placed through the fistula. OUTCOME MEASUREMENTS (1) success rate of stent implantation; (2) outflow of intestinal contents after implantation; (3) tolerated exercise time; (4) receiving definite operation time for intestinal fistula; (5) time to recovery of enteral nutrition. The t-test was used to compare the outflow amount of intestinal content before and after the stent implantation and the tolerated exercise time. The changes of the outflow amount of intestinal content and tolerated exercise time were analyzed by repeated measurement ANOVA. Results: Seventeen EAF patients with open abdomen included 13 males and 4 females. All the patients successfully received intestinal fistula stent implantation. Gastrointestinal angiography 2 days after implantation showed that the digestive tract was unobstructed, and the stent was successfully kept in place until definite surgery. No stent implantation-related adverse reactions were found in patients undergoing definite intestinal fistula surgery. The average outflow amount of intestinal fluid within 7 days after implantation decreased from (702.7±198.9) ml/d to on the first day after implantation (45.8±22.4) ml/d on the 7th day(F=10.380, P<0.001). The ambulatory time and exercise time of patients continued to increase after stent implantation. The average tolerated exercise time within 14 days after stent implantation increased from (9.1±3.8) min/d to (106.9±21.8) min/d (F=41.727, P<0.001). Within 120 days after stent implantation, 15 patients successfully underwent definite surgery for intestinal fistula and reconstruction of abdominal wall. Patients needed a median (IQR) of 3 (2, 5) days to recover enteral nutrition. The average time from stent placement to surgery was (87.2±17.6) days. Two patients died of severe abdominal infection with multiple organ failure. Conclusion: 3D printing fistula stent can significantly and the outflow of intestinal contents and the difficulty of nursing, and help to restore enteral nutrition and rehabilitation exercise as soon as possible in EAF patients with open abdomen.

Waardenburg syndrome (WS) type IV is characterized by pigmentary abnormalities, deafness and Hirschsprung's disease. This syndrome can be triggered by dysregulation of the SOX10 gene, which belongs to the SOX (SRY-related high-mobility group-box) family of genes. We discuss the first known case of a SOX10 frameshift mutation variant defined as c.895delC causing WS type IV without Hirschsprung's disease. This female patient of unrelated Kuwaiti parents, who tested negative for cystic fibrosis and Hirschsprung's disease, was born with meconium ileus and malrotation and had multiple surgical complications likely due to chronic intestinal pseudo-obstruction. These complications included small intestinal necrosis requiring resection, development of a spontaneous fistula between the duodenum and jejunum after being left in discontinuity, and short gut syndrome. This case and previously reported cases demonstrate that SOX10 gene sequencing is a consideration in WS patients without aganglionosis but with intestinal dysfunction.

The role and efficacy of exclusive enteral nutrition (EEN) in the treatment of luminal Crohn's disease (CD) has been well established over the last 2 decades. Consequently, in many centers nutritional therapy is now considered first line therapy in the induction of remission of active CD. However, the use of nutritional therapy in complicated CD has yet to be fully determined. This article aimed to review case reports and clinical trials published in the last decade that have considered and evaluated nutritional therapy in the setting of complicated CD in children and adults. Published literature focusing upon the use of nutritional therapy as part of medical therapy in the management of complicated CD were identified and reviewed. Although there continue to be various interventions utilized for complicated CD, the currently available literature demonstrates that nutritional therapies, especially EEN, have important roles in the management of these complex scenarios. Further assessments, involving large numbers of patients managed with consistent approaches, are required to further substantiate these roles.

Crohn disease has a wide spectrum of clinical presentations and rarely can present with complications such as a bowel stricture or fistula. In this case report, we describe a 17-year-old male who presented with a history of recurrent anterior abdominal wall abscesses and dysuria. He was diagnosed with Crohn disease and also found to have a fistulous communication between the terminal ileum and a patent urachus. An ileocecectomy with primary anastomosis and complete resection of the abscess cavity was performed. He is on azathioprine for maintenance therapy and currently in remission. Clinicians should have a high index of suspicion for this complication in Crohn disease patients presenting with symptoms suggestive of urachal anomalies such as suprapubic abdominal pain, dysuria, umbilical discharge, and periumbilical mass.

In this report, we present a case of successful treatment of a bowel fistula in the open abdomen by perforator flaps and an aponeurosis plug. A 70-year-old man underwent total gastrectomy and developed anastomotic leakage and dehiscence of the abdominal wound a week later. He was dependent upon extracorporeal membrane oxygenation, continuous hemodiafiltration, and a respirator. Bowel fluids contaminated the open abdomen. Two months after the gastric operation, a plastic surgery team, in consultation with general surgeons, performed perforator flaps on both sides and constructed, as it were, a bridge of skin sealing the orifice of the fistula. The aponeurosis of the external oblique muscle was elevated with the flap to be used as a plug. The perforators of the flaps were identified on preoperative and intraoperative ultrasonography. This modality allowed us to locate the perforators precisely and to evaluate the perforators by assessing their diameters and performing a waveform analysis. The contamination decreased dramatically afterwards. The bare areas were gradually covered by skin grafts. The fistula was closed completely 18 days after the perforator flap. An ultrasoundguided perforator flap with an aponeurosis plug can be an option for patients suffering from an open abdomen with a bowel fistula.

Pseudoaneurysms of the cystic artery and cholecystoduodenal fistula formation are rare complications of cholecystitis and either may result from an inflammatory process in the abdomen. A 68-year-old man admitted with acute cholecystitis subsequently developed massive upper gastrointestinal (GI) bleeding. Abdominal computed tomography showed acute calculous cholecystitis and hemobilia secondary to bleeding from the cystic artery. Angiography suggested a ruptured pseudoaneurysm of the cystic artery. Upper GI endoscopy showed a deep active ulcer with an opening that was suspected to be that of a fistula at the duodenal bulb. The patient was managed successfully with multimodality treatment that included embolization followed by elective laparoscopic cholecystectomy. Presently, there is no clear consensus regarding the clinical management of this disease. We have been able to confirm various clinical features, diagnoses, and treatments of this disease through a literature review. A multidisciplinary approach through interagency/interdepartmental collaboration is necessary for better management of this disease.

A fistula between the renal pelvis and duodenum (pyeloduodenal fistula) is very rare. It can occur spontaneously or after trauma to one of these organs. A spontaneous pyeloduodenal fistula is usually caused by chronic inflammation, including reactions to foreign bodies, nephrolithiasis, benign and malignant neoplasms, as well as pyogenic infections. The main treatment to date has been surgery. We encountered one case of pyeloduodenal fistula found during an evaluation for abdominal discomfort in a 39-year-old female. Pyeloduodenal fistula was diagnosed by upper gastrointestinal endoscopy and abdominal computed tomography, and it was caused by direct invasion of nephrolithiasis. Surgical operation was recommended, but the patient refused. The patient has been free of symptoms for four years. Herein, we report an unusual case of pyeloduodenal fistula without surgical management and relevant literature review.
