Congenital duodenal obstruction repair with and without transanastomotic tube feeding: a systematic review and meta-analysis

OBJECTIVE

To determine the impact of transanastomotic tube (TAT) feeding in congenital duodenal obstruction (CDO).

DESIGN

Systematic review with meta-analysis.

PATIENTS

Infants with CDO requiring surgical repair.

INTERVENTIONS

TAT feeding following CDO repair versus no TAT feeding.

MAIN OUTCOME MEASURES

The main outcome was time to full enteral feeds. Additional outcomes included use of parenteral nutrition (PN), cost and complications from either TAT or central venous catheter. Meta-analyses were undertaken using random-effects models (mean difference (MD) and risk difference (RD)), and risk of bias was assessed using the Risk Of Bias In Non-randomised Studies - of Interventions (ROBINS-I) tool.

RESULTS

Twelve out of 373 articles screened met the inclusion criteria. All studies were observational and two were prospective. Nine studies, containing 469 infants, were available for meta-analysis; however, four were excluded due to serious or critical risk of bias. TAT feeding was associated with reduced time to full enteral feeds (-3.34; 95% CI -4.48 to -2.20 days), reduced duration of PN (-6.32; 95% CI -7.93 to -4.71 days) and reduction in nutrition cost of £867.36 (95% CI £304.72 to £1430.00). Other outcomes were similar between those with and without a TAT including inpatient length of stay (MD -0.97 (-5.03 to 3.09) days), mortality (RD -0.01 (-0.04 to 0.01)) and requirement for repeat surgery (RD 0.01 (-0.03 to 0.05)).

CONCLUSION

TAT feeding following CDO repair appears beneficial, without increased risk of adverse events; however, certainty of available evidence is low. Earlier enteral feeding and reduced PN use are known to decrease central venous catheter-associated risks while significantly reducing cost of care.

Aorto-mesenteric compass syndrome (Wilkie's syndrome) in the differential diagnosis of chronic abdominal pain

A woman in her 40s was admitted to hospital with weight loss, asthenia, persistent abdominal pain and post-prandial nausea and vomiting. Other comorbidities were anxiety-depressive disorder, gastro-oesophageal reflux disease and fibrocystic mastopathy. On admission her body mass index (BMI) was 15.57 kg/m2 with a reported weight loss of 6 kg during the last 3 months. The patient underwent a double contrast abdominal CT scan, which showed that the third portion of the duodenum appeared to be compressed between the superior mesenteric artery and the abdominal aorta. After a multidisciplinary evaluation, a conservative approach and nutritional supplementation was decided upon and administered. At the 1-year follow-up the symptoms had greatly improved; the epigastric pain, although persistent, was reduced, also due to the weight gain to 50 kg (BMI 19.5 kg/m2). Wilkie's syndrome, in its acquired form, predominantly affects young women after rapid weight loss. In the diagnostic work-up, case history, physical examination and radiological findings play a key role.

WallFlex® and Evolution® Duodenal Stents Have Similar Efficacy but Different Safety for Malignant Gastric Outlet Obstruction

BACKGROUND

The WallFlex® and Evolution® stents are the most widely used duodenal stents, but no study has compared them.

AIMS

We aimed to compare the efficacy and safety of WallFlex® and Evolution® stents for malignant gastric outlet obstruction.

METHODS

We included all consecutive patients who were treated for malignant gastric outlet obstruction with WallFlex® or Evolution® self-expandable metal uncovered duodenal stents between 2013 and 2020. Multivariable Cox models were performed to assess duodenal stent failure, as defined by gastric outlet obstruction necessitating another duodenal stent.

RESULTS

We included 129 patients: 74 received a WallFlex® stent and 55 received an Evolution® stent. The non-failure rate was of 68% (95%CI 55-84) and 65% (95%CI 50-84) at 6 months and of 48% (95%CI 32-73) and 45% (95%CI 27-74) at 1 year, with the WallFlex® and Evolution® stents, respectively. The median time to duodenal stent failure was 10.5 months in the WallFlex® group and 9.3 months in the Evolution® group. The type of duodenal stent was not associated with duodenal stent failure (p logrank = 0.43, adjusted hazard ratio 1.55; 95%CI 0.77-3.14). The overall survival was similar between the two groups (p logrank = 0.92). Three patients had complications due to Evolution® stents; it consisted in dismantled stents that led to hemorrhage in one patient.

CONCLUSIONS

WallFlex® and Evolution® duodenal stents had similar efficacy for malignant gastric outlet obstruction. There were more adverse events with Evolution® stents.

Rare Complication of Strongyloidiasis in Vietnam: A Case of Venous Thromboembolism and Duodenal Obstruction

Strongyloidiasis, a chronic helminth infection caused by the parasitic nematode Strongyloides stercoralis, has various clinical manifestations. Although rare, duodenal obstructions and venous thromboembolism are possible complications of strongyloidiasis. This paper presents the case of a 47-year-old Vietnamese male with a history of right lower limb edema, anorexia, nausea, vomiting, diarrhea, and abdominal discomfort lasting for four months. Venous Doppler ultrasound detected a thrombus in the right femoral vein, while an abdominal CT scan revealed a mass lesion suggestive of a lower bile duct tumor. Esophageogastroduodenoscopy showed a friable duodenal cap mucosa with multiple ulcers and edematous mucosa of the second part of the duodenum that caused a partial lumen obstruction. The final histological examination of the biopsy specimen revealed chronic duodenitis with larvae consistent with Strongyloides stercoralis. The patient was treated with Ivermectin for two weeks and anticoagulation therapy for three months. After treatment and a six-month follow-up, the patient's gastrointestinal symptoms and leg swelling resolved completely. This is the first documented case of a patient in Vietnam with strongyloidiasis who presented with venous thromboembolism and duodenal obstruction.

Gastrojejunostomy versus endoscopic duodenal stent placement for gastric outlet obstruction in patients with unresectable pancreatic cancer: a propensity score-matched analysis

BACKGROUND

Treatments for patients with gastric outlet obstruction (GOO) due to unresectable pancreatic cancers (URPC) include gastrojejunostomy (GJJ) and endoscopic duodenal stent placement (EDSP). This study compared the efficacy and safety of GJJ and EDSP in patients with GOO due to URPC.

METHODS

This study retrospectively evaluated consecutive patients with GOO due to URPC who underwent GJJ or EDSP between April 2016 and March 2020. The efficacy and safety of GJJ and EDSP were compared with propensity score analysis. Subgroup analyses of overall survival (OS) were compared after propensity matching.

RESULTS

Data were obtained from 54 patients who underwent GJJ and from 73 who underwent EDSP at five tertiary care hospitals. After propensity matching, OS was significantly longer in patients who underwent GJJ than EDSP (110 vs. 63 days, respectively; p = 0.019). Evaluation of long-term adverse events showed that the frequency of cholangitis and obstructive jaundice was significantly lower in the matched GJJ than in the matched EDSP group (p = 0.012). Subgroup analyses showed that OS in patients with good performance status (PS; p = 0.041), biliary obstruction (p = 0.007), and duodenal obstruction near the papilla (p = 0.027), and those receiving chemotherapy (p = 0.010), was significantly longer in the matched GJJ group than in matched EDSP group.

CONCLUSION

GJJ provides longer OS than EDSP for patients with GOO caused by URPC, especially for patients with good PS, biliary obstruction, and duodenal obstruction near the papilla, and those receiving chemotherapy.

Effect of trisomy 21 on long-term gastrointestinal outcomes in duodenal atresia

PURPOSE

We aimed to determine if Trisomy 21 (T21) affected gastrointestinal outcomes for children with duodenal atresia (DA).

METHODS

We identified children born with DA between 1991 and 2017. Cases were divided into DA with T21 and DA without T21. Ten healthy controls per case were included. Esophageal, ulcerative, obstructive and stomach complaints were assessed. Risk ratios (RR), rate ratios (RaR) and Cox models were constructed. Analyses were performed for cases versus controls, and for T21 cases versus non-T21 cases.

RESULTS

DA cases totaled 52: 22 had T21 and 30 did not. There were 520 controls. DA cases had more gastrointestinal complaints than controls. T21 cases were at greater risk and frequency of esophageal disease than non-T21 cases (RR = 4.08, p = 0.002, RaR = 69.8, p < 0.001). T21 and non-T21 cases were equally likely to present with obstruction (RR = 0.91, p = 1), but T21 cases complained of obstructive symptoms less (RaR = 0.57, p = 0.003). T21 and non-T21 cases had the same risk of stomach diseases, but T21 cases complained more frequently (RaR = 6.20, p < 0.001). Cox models supported these observations. T21 did not affect ulcerative diseases.

CONCLUSION

DA cases had more gastrointestinal problems than controls. T21 increased esophageal and gastric complaints in DA cases but did not affect ulcerative and obstructive complaints.

[Superior mesenteric artery syndrome in gastric cancer: a case report]

Superior mesenteric artery syndrome or Wilkie syndrome is due to the compression of the third duodenum between the superior mesenteric artery and the aorta. It causes acute or chronic upper bowel occlusion. Abdominal CT scan facilitates the diagnosis. Severe malnutrition is its main etiological factor. Medical treatment can be based on aspiration of gastric contents and parenteral nutrition. If this fails, surgery is necessary. We here report the case of a 46-year-old patient, with a history of smoking, presenting with profuse postprandial bile and food vomiting. He had had weight loss of 7% over a period of 6 months. Upper GI endoscopy revealed non-stenotic antro-pyloric tumour mass. Histological examination showed poorly differentiated tubular gastric adenocarcinoma. Staging was without any peculiarity and allowed for the detection of superior mesenteric artery syndrome at an angle of 8°C. The patient received parenteral nutrition for 10 days, followed by inferior pole gastrectomy and gastrojejunal anastomosis (omega loop). The postoperative course was uneventful. Adjuvant chemotherapy was indicated.

Endoscopic duodenal stent placement versus gastrojejunostomy for unresectable pancreatic cancer patients with duodenal stenosis before introduction of initial chemotherapy (GASPACHO study): a multicenter retrospective study

BACKGROUND

Endoscopic duodenal stent placement is an alternative technique to gastrojejunostomy for gastric outlet obstruction due to pancreatic cancer. We compared the efficacy of endoscopic duodenal stent placement with that of gastrojejunostomy for treating patients with pancreatic cancer who are candidates for intensive combination chemotherapies as the first line of treatment.

METHODS

This retrospective observational study included 100 patients from 18 institutions in Japan. Inclusion criteria were as follows: (1) cytologically or histologically confirmed adenocarcinoma of the pancreas, (2) good performance status, (3) gastric outlet obstruction scoring system score of 0-1 and (4) no history of treatment for pancreatic cancer.

RESULTS

There was no significant difference in the background characteristics of patients in the endoscopic duodenal stent placement (n = 57) and gastrojejunostomy (n = 43) groups. The median overall survival in the endoscopic duodenal stent placement and gastrojejunostomy groups was 5.9 and 6.0 months, respectively. Clinical success was achieved in 93 cases; the median time to food intake resumption was significantly shorter in the endoscopic duodenal stent placement group (median: 3 days, n = 54) than in the gastrojejunostomy group (median: 5 days, n = 43). Chemotherapy was introduced in 63% of the patients in both groups after endoscopic duodenal stent placement or gastrojejunostomy. Chemotherapy was started earlier in the endoscopic duodenal stent placement group (median: 14 days) than in the gastrojejunostomy (median: 32 days) group.

CONCLUSIONS

Endoscopic duodenal stent placement showed similar or better clinical outcomes than gastrojejunostomy. Thus, it might be a promising option in patients with good performance status.

Mitchell-Riley Syndrome: Improving Clinical Outcomes and Searching for Functional Impact of RFX-6 Mutations

AIMS/HYPOTHESIS

Caused by biallelic mutations of the gene encoding the transcription factor RFX6, the rare Mitchell-Riley syndrome (MRS) comprises neonatal diabetes, pancreatic hypoplasia, gallbladder agenesis or hypoplasia, duodenal atresia, and severe chronic diarrhea. So far, sixteen cases have been reported, all with a poor prognosis. This study discusses the multidisciplinary intensive clinical management of 4 new cases of MRS that survived over the first 2 years of life. Moreover, it demonstrates how the mutations impair the RFX6 function.

METHODS

Clinical records were analyzed and described in detail. The functional impact of two RFX6^R181W and RFX6^V506G variants was assessed by measuring their ability to transactivate insulin transcription and genes that encode the L-type calcium channels required for normal pancreatic beta-cell function.

RESULTS

All four patients were small for gestational age (SGA) and prenatally diagnosed with duodenal atresia. They presented with neonatal diabetes early in life and were treated with intravenous insulin therapy before switching to subcutaneous insulin pump therapy. All patients faced recurrent hypoglycemic episodes, exacerbated when parenteral nutrition (PN) was disconnected. A sensor-augmented insulin pump therapy with a predictive low-glucose suspension system was installed with good results. One patient had a homozygous c.1517T>G (p.Val506Gly) mutation, two patients had a homozygous p.Arg181Trp mutation, and one patient presented with new compound heterozygosity. The RFX6^V506G and RFX6^R181W mutations failed to transactivate the expression of insulin and genes that encode L-type calcium channel subunits required for normal pancreatic beta-cell function.

CONCLUSIONS/INTERPRETATION

Multidisciplinary and intensive disease management improved the clinical outcomes in four patients with MRS, including adjustment of parenteral/oral nutrition progression and advanced diabetes technologies. A better understanding of RFX6 function, in both intestine and pancreas cells, may break ground in new therapies, particularly regarding the use of drugs that modulate the enteroendocrine system.

Endoscopic Ultrasound-guided Fine Needle Aspiration for the Diagnosis of Duodenal Stenosis Due to Urothelial Carcinoma

Upper tract urothelial carcinoma (UTUC) initially presents with hematuria and hydronephrosis. We report a case of UTUC presenting with initial findings of duodenal stenosis before the appearance of hydronephrosis. A 59-year-old man presented with upper abdominal symptoms on his initial visit. Esophagogastroduodenoscopy (EGD) revealed circumferential stenosis at the descending part of the duodenum. However, the underlying cause of duodenal stenosis was unknown as repeated histopathological examinations of endoscopic biopsy specimens showed no specific findings. We then performed endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) of the thickened duodenal wall, and successfully diagnosed duodenal metastasis of UTUC. EUS-FNA is an effective diagnostic method in cases in which the cause of duodenal stenosis is unknown.

Anaesthesia for Antenatal Diagnosed Duodenal Atresia with Undiagnosed Persistent Pulmonary Hypertension of Neonate

Conversion of fetal circulation to adult-type occurs immediately after birth but neonates with problems in the development of pulmonary vasculature are prone to revert back to fetal circulation. This phenomenon is known as flip-flop circulation which may be induced perioperatively and as such anesthesiologist are central to its management. We report a case of term neonate planned for repair of duodenal atresia that despite having no respiratory symptom preoperatively developed severe hypoxemia under anesthesia that was even unresponsive to 100% oxygen. The intraoperative hemodynamics of the neonate was managed along with supportive care successfully. A postoperative echocardiogram confirmed the evidence of persistent pulmonary hypertension of the newborn. Keywords: Duodenal atresia; flip flop circulation; neonates; persistent pulmonary hypertension of newborn.

A rare case of reverse midgut rotation and jejunal transmesenteric internal hernia in an adult with Beckwith-Wiedemann syndrome

Intestinal malrotation is a rare congenital condition with an incidence in adulthood between 0,0001% and 0,19%, affecting nearly 1:500 live births. It results from an abnormal rotation of the bowel within the peritoneal cavity during embryogenesis. Generally it involves both small and large bowel, leading to an increased risk of intestinal obstruction. Depending on which phase of midgut embryological development is stopped or disrupted, a variety of anatomic anomalies may occur. Reverse rotation is the most rare form of intestinal malrotation (2-4%) and is more common in women. It origins from premature return of the caudad midgut into the abdominal cavity while the duodenal loop rotates clockwise during fetal life, between 4th and 12th gestational week. The cecum begins its migration and shifts to the right behind the superior mesenteric artery (SMA). As a result the transverse colon lies behind the duodenum and the SMA. Malrotation's most common clinical manifestations in neonates are acute duodenal obstruction and midgut volvulus, lifethreatening conditions resulting in acute bowel obstruction and ischemia. In adult patients the risk of volvulus decreases and clinical presentation is more aspecific, leading to delayed diagnosis, that may cause dangerous consequences. We report a rare case of an adult male patient presenting with acute abdominal symptoms caused by a reverse midgut rotation in a Beckwith-Weidemann Syndrome (BWS), a rare genetic disorder characterized by the association between adrenal cytomegaly, hemihypertrophy, macroglossia, omphalocele and pancreatic islet hyperplasia. KEY WORDS: Beckwith-Wiedemann syndrome, Reverse midgut rotation, Jejunal transmesenteric hernia.

Adolescent with Superior Mesenteric Artery Syndrome

The underlying etiologies of paediatric bowel obstruction are wide ranging. It can be divided into proximal and distal bowel obstruction. Amongst the different etiologies of the proximal bowel obstructions at the level of the duodenum, there are a few etiologies including duodenal atresia, internal hernias, intestinal malrotation, annular pancreas etc. Superior mesenteric artery syndrome is amongst one of these differential diagnoses which is more prevalent in the adolescent age group. We describe the imaging features of this entity and its demographics, imaging characteristics, treatment and prognosis.

Complete Annular Pancreas with Concurrent Entero-Pancreatico-Biliary Symptoms in Adult: A Case Report

Complete Annular pancreas (AP) is a rare congenital anomaly, often presented and operated at the early age of life. Adult presentation group usually presents with either biliary or duodenal or pancreatic symptoms. We report a case of 43 years old female presenting with concurrent enteric, biliary and pancreatic symptoms admitted on April 2016 in Hepatobiliary and Pancreatic Surgery Department of BSMMU, Dhaka, Bangladesh. A complete type of annular pancreas with partial duodenal stenosis and dilated common bile duct was observed during laparotomy. We performed gastrojejunostomy as well as hepaticojejunostomy (Roux-en-Y anastomosis). Patient was discharged in a good symptom free condition. Complete Annular Pancreas can present at any age, with any one or all of the biliary, pancreatic or duodenal symptoms. Surgery is the treatment of choice and has a good outcome.

[Difficult Airway Management in a Low Birth Weight Infant Using an Upper Gastrointestinal Endoscope]

We report a successful tracheal intubation in a low birth weight infant with difficult airway by using an upper gastrointestinal endoscope. A 1-day-old female weighing 1.8 kg having micrognathia, lateral facial cleft, and bilateral microtia suggestive of Goldenhar syn- drome complicated with total anomalous pulmonary venous connection was scheduled for surgical repair of duodenal atresia. Awake intubation was planned because of anticipated difficult intubation. Direct laryn- goscopy with Miller blade (size 0) after intravenous lidocaine did not visualize the larynx or epiglottis (Cor- mack-Lehane grade 4). After several failed attempts at intubation using BURP procedure, Pentax Airway Scope? equipped with a neonatal-type Intlock* (ITL- N) was tried but a good view of the larynx was not obtained because of the narrow oral cavity and copious secretion. After failed attempts with Airway Scope?, an upper gastrointestinal endoscope was inserted into the oral cavity and equipped insufflation and suctioning of the secretion were utilized, which provided a good view of the vocal cords and enabled nasotracheal intu- bation. An upper gastrointestinal endoscope could provide a good view of the larynx by using insufflation, and suc- tioning, and can be one of the useful devices for tra- cheal intubation of difficult airway.

Recurrent duodenal atresia: a case report

BACKGROUND

Duodenal atresia is a rare disorder occurring in 1 in 10,000 live births. Duodenal atresia is associated with trisomy 21: 5-15% of trisomy 21 cases have duodenal atresia and 30% of duodenal atresia cases are associated with trisomy 21. Some cases of duodenal atresia may be recurrent.

CASE

Two siblings were born with duodenal atresia but no other anomalies. The father of the siblings also had isolated congenital duodenal atresia.

CONCLUSION

Recurrent duodenal atresia should be considered when the condition is discovered prenatally. The etiology may be autosomal dominant inheritance, as with Feingold syndrome, or autosomal recessive inheritance.

Trisomy 21--incidence and outcomes in the first year, in Ireland today

Incidence of Trisomy 21 in Ireland, 1:546 live births, is the highest in Europe. This project aimed to define the incidence of T21 amongst liveborn infants at Cork University Maternity Hospital (CUMH), and to describe neonatal outcomes and progress in their first year. Infants were identified from Social Work department records. A retrospective review of the neonatal inpatient database, outpatient letters and medical charts was performed. Forty three infants with T21 were born in CUMH in 2010 and 2011. Incidence of T21 was 1:411. Antenatal diagnosis was uncommon at 14% (6). 34 (79%) were admitted to the neonatal unit. Co-morbidities included congenital heart disease 22 (51%) and duodenal atresia 2 (5%). Thirty four were followed-up in CUMH outpatient department. Of these, 34 (100%) had thyroid function testing, 29 (85%) ophthalmology and audiology referral, and 7 (21%) were referred for hip review. Mortality rate was 9% (4). Readmission to hospital in the first year of life was 42% (18).

Eye diseases in children in Jordan

OBJECTIVE

To investigate eye diseases in children in Jordan and to see whether it is necessary to conduct a visual screening programme.

METHODS

The study was conducted between July 2010 and July 2012 at four Royal Medical Service hospitals located in northern, eastern, middle and southern parts of Jordan. Children aged (6-14 years) attending paediatric clinics for various reasons were enrolled. Ophthalmologic assessment included visual acuity and anterior and posterior segment examination. Patients with visual acuity of less than 20/20 underwent refraction under cyclopegia.

RESULTS

Of the 3200 children in the study ocular abnormalities were found in 366 (11.4%); 312 (9.8%) had visual acuity less than 20/20 in one or both eyes. Refractive error was seen in 286 (8.9%); while vernal catarrh was the second most common ocular abnormality with 51 (1.6%) patients followed by squint 16(0.5%). Four (0.12%) patients had severe visual impairment and one (0.03%) patient was blind.

CONCLUSION

The prevalence of refractive error was high in school children in the study area. It is important to conduct a visual screening programme in early school years in order to prevent amblyopia.

[Case of tracheal agenesis found during surgery]

We reported a case of tracheal agenesis (TA) that was diagnosed during surgery. A female infant, weighing 1,104 g, was born at the 29 weeks of gestation. She showed severe respiratory distress without crying. Oxygenation was improved by mask ventilation, but tracheal intubation was very difficult. Tracheoesophageal fistula (TEF) was suspected because significant amount of air from nasogastric tube was noticed. Physical examination and X-ray findings suggested Gross E type TEF, duodenal atresia and cloaca. On the second day of life, ligation of TEE gastrostomy and colostomy were scheduled. Although operation was started without problems, ventilation became impossible when TEF was clamped and release of clamping made it possible. Bronchoscopic investigation revealed that tracheal tube was located in the esophagus. We have never doubted the esophageal intubation, because patient was ventilated preoperatively and signs of respiratory distress syndrome were successfully treated by the surfactant replacement therapy through tracheal tube. Type II TA according to Floyd's classification was diagnosed by bronchoscopic and echographic investigations. Distal esophageal ligation, gastrostomy and esophagostomy were performed. She died on the 12th day of life in spite of vigorous ventilatory and cardiovascular support.

Continuous regional application of protease inhibitor in the treatment of acute pancreatitis. An experimental study using closed duodenal obstruction model in dogs

In clinical settings, the effectiveness of protease inhibitors in the treatment of acute pancreatitis has been still controversial. With the concept that sufficient tissue concentration of protease inhibitor in the pancreas has to be included to achieve its potent inhibitory effect, we applied a continuous regional intra-arterial (CRI) application of low-molecular-weight protease inhibitor, nafamostat mesilate (FUT-175), for closed duodenal loop obstruction model in mongrel dogs. The use of CRI application led to a higher concentration of FUT-175 in the pancreatic tissue (4,453 +/- 758 ng/g) when compared with that applied intravenously (905 +/- 48 ng/g). Consequently, pancreatic parenchyma in CRI application animals was remarkably preserved, as assessed by the lower extent of pancreatic necrosis (12.4 +/- 2.6% in CRI vs. 25.6 +/- 1.9% in intravenous). Additionally, the elevation of trypsin-like activity in the pancreas was significantly inhibited in CRI animals. Based on these findings, the dose as well as the route of protease inhibitors should be carefully considered to achieve its beneficial effect.

Superior mesenteric artery syndrome due to an aortic aneurysm in a renal transplant recipient

Superior mesenteric artery (SMA) syndrome is a rare disease in which the third portion of the duodenum is compressed by SMA. There are many causes leading to the SMA syndrome, however it's extremely rare that aortic aneurysm causes a SMA syndrome. We report a case of a successfully treated SMA syndrome due to an abdominal aortic aneurysm in a renal transplant recipient. The patient was a 52-yr-old woman with a thin stature (weight 40 kg, height 164 cm). She received a renal transplant 8 yr before, and had hypertension and abdominal aortic aneurysm. Her SMA syndrome developed in a prolonged supine position for the accidental rib fractures and was diagnosed by clinical and radiological findings. After a surgical correction (resection of an aneurysm and aortobiiliac bypass with an inverted Y graft), her symptoms relieved without deterioration of the graft function.

[Bouveret'S syndrome: gastric outlet obstruction by a gallstone]

This rare syndrome first described by Bouveret in 1896, occurs when a stone migrates through a cholecysto or choledochoduodenal jistula lodging in the duodenal bulb and resulting in obstruction. Up to date, less than 100 cases reported in the literature. This rare type of gallstone ileus can be diagnosed and treated endoscopically, although there are a few previous reports of successful endoscopic, removal. However, surgical removal is safe and effective but the most controversial aspect is the proper treatment, simple enterotomy and removal ofthe gallstone alone or enterolithotomy in association with cholecystectomy and dejinitive correction ofthe biliodigestive fistula. This paper presents a case report of a 65 year old man with gastric outlet obstruction caused by a large gallstone. The diagnose and treatment of this case who was admitted in 1.General Surgical Department of Taksim Teaching and Research Hospital was researched under the reference of recent literature.

An audit of gastroduodenal Crohn disease: clinicopathologic features and management

BACKGROUND

This study was undertaken to assess the clinicopathologic features and management of gastroduodenal Crohn disease.

METHODS

The medical records of 54 patients with gastroduodenal Crohn disease treated between 1958 and 1997 were reviewed.

RESULTS

Gastroduodenal Crohn disease occurred in association with disease elsewhere in 52 patients (96%). The commonest pathology was stricture (n = 41), followed by ulceration (n = 4) and duodenocutaneous fistula (n = 2). Medical treatment was initially attempted in 31 patients, of whom 12 required no surgical treatment for gastroduodenal disease. Nineteen patients required surgery for gastroduodenal obstruction or fistula despite medical treatment. Overall, 33 patients (61%) required surgery; the indication was obstruction in 30, duodenocutaneous fistula in 2, and bleeding in 1. There was one postoperative death because of persistent bleeding and intraabdominal sepsis after oversewing of a bleeding ulcer. In obstructive disease 16 patients were treated by bypass surgery, 10 by strictureplasty, and 4 by gastrectomy. After surgery for obstructive disease anastomotic leak developed in three patients, and persistent gastric outlet obstruction was seen in six patients. In the long term 11 patients required reoperation for anastomotic obstruction (n = 9) or stomal ulceration (n = 2). For duodenocutaneous fistula one patient underwent simple closure of fistula, and the other patient duodenojejunostomy. Both of these patients developed an intra-abdominal abscess without evidence of leak. There has been no fistula recurrence.

CONCLUSIONS

Gastroduodenal Crohn disease is a complex and difficult problem that is associated with serious complications and need for reoperation.
