Natural history of anastomotic leakage after elective stoma closure.

INTRODUCTION: Elective stoma closure (ESC) is a common procedure. The main complication of ESC is anastomotic leakage, which can be revealed by peritonitis or an enterocutaneous fistula (ECF). The objective of the present study was to describe the natural history of AL after ESC. PATIENTS AND METHODS: Between January 2015 and March 2020, all patients having undergone AL after loop or double-barreled ESC were included in a retrospective, single-center study. The rate of ECF and peritonitis at presentation, the success rate of a conservative treatment and the factors associated with the success of healing of ECF were evaluated. RESULTS: From January 2015 to March 2020, 619 patients underwent a loop or double-barreled ESC in our department. The AL rate was 6.3% (n=39). The leakage was revealed by an ECF in 72% of cases (n=28). The mean±standard deviation time between the stoma closure and the diagnosis of the AL was 6±4 days. Conservative treatment was successful in 24 (85%) of the 28 patients with ECF, with a mean±SD time to recovery of 6.6±9.4 months. In a univariate analysis, none of the conservative treatments was significantly associated with healing of the ECF. CONCLUSION: AL is not rare and is mainly revealed by an ECF. Although the fistula heals in most cases, both the surgeon and the patient must be aware that the time to recovery is long.

Severe erosive gingivostomatitis in a patient treated by vedolizumab.

Vedolizumab is a humanized monoclonal antibody that binds to the human a4ß7 integrin and is approved for use in inflammatory bowel diseases. We describe a patient with severe, refractory erosive gingivostomatitis, which appeared a few days after the first dose of vedolizumab and resolved after discontinuation of the drug. We believe the gingivostomatitis to be a direct side effect of vedolizumab, rather than an extraintestinal manifestation of the underlying inflammatory bowel diseases. The clinicians need to be aware of this adverse event, which could be mistakenly considered as an extraintestinal manifestation of inflammatory bowel diseases.

Endoscopic or surgical ampullectomy for intramucosal ampullary tumor: the patient populations are not the same.

PURPOSE: To evaluate and compare the results of endoscopic ampullectomy (EA) and surgical ampullectomy (SA) for benign tumors. MATERIAL AND METHOD: From 2005 to 2018, 66 patients were eligible for ampullectomy (adenoma, ultrasound grading≤T1, N0). The principal endpoint was the rate of complete resection: R0 resection without local recurrence and no recurrence after a single operative procedure and with final pathology confirming the operative indications. Secondary endpoints were: morbidity, mean length of stay (LOS), preoperative and final pathology results, complete (or incomplete) resection, mean duration of follow-up, local recurrence rate and late complications (biliary stricture). RESULTS: Among the 41 patients eligible for EA, 36 ampullectomies were performed, while five were referred for SA because of intracanalar invasion that had not been diagnosed initially. The rate of complete treatment was 48% (13/27), the morbidity was 10%; the LOS was 3.3days; no adenomatous lesion was found on the definitive pathology in 9 patients (25%). The resection was R1 in 30% but there were no R2 resections. The median duration of follow-up was 20months, the rate of local recurrence was 22% and the rate of late biliary stricture was 2%. Among the 30 patients who were eligible for SA, (25 plus the five referred by endoscopists after intracanalar invasion was found), SA was eventually performed in 24: five patients were converted to pancreatoduodenectomy, one patient was found to have metastatic disease and had no resection. An extemporaneous frozen-section pathology examination was performed in 22 of the 24 SA patients and confirmed healthy margins on the bile ducts and pancreatic ducts. The rate of complete treatment was 71% (17/24), morbidity was 35%; LOS was 10days; seven patients (29%) were found to have invasive adenocarcinoma, and six of these (86%) underwent subsequent pancreatoduodenectomy. None of the resections were R1 or R2; median follow-up was 21months; there was no local recurrence; biliary stricture rate was 8%. CONCLUSION: The short-term and long-term results of patients undergoing endoscopic or surgical ampullectomy are different. The lesions resected by EA were less advanced, with simpler postoperative course. The lesions for which SA was performed were more advanced, and had more morbid sequelae, but with a better rate of complete treatment and better long-term results.

Cost-effectiveness analysis of stent type in endoscopic treatment of gastric leak after laparoscopic sleeve gastrectomy.

BACKGROUND: Gastric leak is the most feared surgical postoperative complication after sleeve gastrectomy. An endoscopic procedure is usually required to treat the leak. No data are available on the cost-effectiveness of different stent types in this procedure. METHODS: Between April 2005 and July 2016, patients with a confirmed gastric leak undergoing endoscopic treatment using a covered stent (CS) or double-pigtail stent (DPS) were included. The primary objective of the study was to assess overall costs of the stent types after primary sleeve gastrectomy. Secondary objectives were the cost-effectiveness of each stent type expressed as an incremental cost-effectiveness ratio (ICER); the incremental net benefit; the probability of efficiency, defined as the probability of being cost-effective at a threshold of €30 000, and identification of the key drivers of ICER derived from a multivariable analysis. RESULTS: One hundred and twelve patients were enrolled. The overall mean costs of gastric leak were €22 470; the mean(s.d.) cost was €24 916(12 212) in the CS arm and €20 024(3352) in the DPS arm (P = 0·018). DPS was more cost-effective than CS (ICER €4743 per endoscopic procedure avoided), with an incremental net benefit of €25 257 and a 27 per cent probability of efficiency. Key drivers of the ICER were the inpatient ward after diagnosis of gastric leak (surgery versus internal medicine), type of institution (private versus public) and duration of hospital stay per endoscopic procedure. CONCLUSION: DPS for the treatment of gastric leak is more cost-effective than CS and should be proposed as the standard regimen whenever possible.

Surgical conservative treatment of recurrent bleeding duodenal ulcer.

BACKGROUND/AIMS: Endoscopic hemostasis and proton pump inhibitors (PPI) have decreased the incidence of rebleeding and reduced the need for surgery for bleeding duodenal ulcer (BDU). The gold standard surgical treatment of BDU remains vagotomy-antrectomy. Currently, no recommendation is made on the best procedure when emergency surgery is necessary. The aim of this study was to assess the results of a systematic conservative treatment (CT): under-running bleeding gastroduodenal artery (GDA) and ulcer suture through a duodenotomy with (CT+L group) or without (CT group) GDA double ligation along with continuous intravenous PPI. METHODOLOGY: From 1995 to 2006, 22 consecutive patients (11 per group) underwent emergency surgery for BDU. Mean age was 63 +/- 18 years, ASA score 2.64 +/- 0.7. Ten patients (45%) presented collapse. Mean transfusion number was 11 +/- 9, number of therapeutic endoscopies 1.7 +/- 1, and Rockall score 6 +/- 2. RESULTS: Overall, 2 patients (9%) had rebleeding and 5 patients (22%) died. No death was reported secondary to rebleeding. In the CT+L group, 9 patients (82%) had intravenous PPI, no patient had rebleeding and 2 patients died (22%). CONCLUSIONS: Surgical CT of BDU with continuous PPI is effective, with a low rate of rebleeding. The standard use of vagotomy-antrectomy is questionable.

[Fistulisation of a tubercular adenopathy in the oesophagus. About a paucisymptomatic form]. / Fistulisation d'une adénopathie tuberculeuse à l'oesophage. A propos d'une forme frustre.

The authors present the case of a cervico-mediastinal mass which disappeared spontaneously. The clinical presentation and the image of a fistula during the oesophagoscopy are in favour of the fistulisation of a tubercular adenopathy in the oesophagus. This pathology is rare. This observation is original by the delay of diagnosis due to a dysphagie summarizing the clinical signs and the spontaneously favorable evolution of the fistula.

[Self expanding metallic stent in the management of malignant colonic obstruction]. / L'endoprothèse colique métallique expansive (ECM) dans les occlusions coliques d'origine tumorale.

INTRODUCTION: Fifteen to thirty percent of colonic cancers are diagnosed at acute colic obstruction stage. In this situation surgery is associated with a high morbi-mortality. The self-expandable metallic stents (SEM) have two objectives: (a) resolution of the obstructive to allow secondary planified radical surgical procedure; (b) palliative in the event of advanced disease. PATIENTS AND METHODS: From May 2001 to December 2002, 11 patients, mean age 75 +/- 8 years, presenting with acute colic obstruction were initially treated by SEM placed by endoscopy. Four patients were classified score ASA 4. Ten patients had a colonic cancer, and a patient presented a peritoneal carcinomatosis from an ovarian carcinoma. Overall five patients had a carcinomatosis. Stenosis, mean length 4 +/- 3 cm, were located on the left colon. In five patients the SEM was proposed as a palliative treatment. RESULTS: Successfully placement of SEM was obtained in 10 (91%) patient without perforation. Three complications (bleeding, reobstruction, migration) were observed. Clinical success (colonic decompression within 96 h without endoscopic or surgical reintervention) was observed in nine out of ten (90%) patients. Six patients had a SEM with curative attempt allowing (i) colonic resection (9 +/- 2 days) without stomy (one postoperative death) in five patients; (ii) a colo-colic derivation for diffuse carcinomatosis discovered peroperatively. A diverting colostomy was carried out in two of the four patients (j6, j30) (reobstruction, migration) for whom the SEM had been proposed as palliative treatment. CONCLUSIONS: This study confirms that SEM and surgery are not competitive but complementary techniques. When the SEM is placed with curative attempt, it allows resolution of the obstructive syndrome and secondary planified radical surgical procedure under better conditions. The results observed in the palliative SEM group suggested to reconsider this indication.

[The treatment of biliary stenosis with metallic stents: the need for multidisciplinary decision making]. / Traitement de la sténose biliaire par prothèse métallique: nécessité d'une décision multidisciplinaire.

A patient presented with a cholangiocarcinoma of the common bile duct; it was initially considered unresectable leading to the placement of the metallic stent whose upper end extended beyond the convergence of the hepatic ducts. The metallic biliary stent became obstructed and so encrusted as to be unremovable; the patient required a left hepatectomy with resection of the stent and the biliary convergence in addition to a pancreatoduodenectomy in order to resect his primary lesion This difficult situation emphasizes that, whenever there is doubt as to the resectability of a biliary lesion, the decision to place a metallic stent should be the fruit of a thorough medico-surgical discussion; where there is any doubt, a plastic stent which is more easily removable should be placed.

Aortic thrombosis and ulcerative colitis.

Arterial thrombotic accidents in the course of inflammatory bowel disease are rare. They generally affect young adults whose disease is active. We observed a case of aortic and renal arterial thrombosis in a 40-year-old woman who was suffering from ulcerative colitis. Surgical thrombectomy ensured good postoperative results, without any ischemic or renal sequelae. Six days later the patient presented with distal thrombosis of the splenic artery, which receded under anticoagulant treatment. The physiopathology of thromboembolic events in the course of inflammatory bowel disease is uncertain. Such events result from a state of hypercoagulability of various mechanisms, which can be observed in active inflammatory bowel disease. This possibility of serious arterial thrombosis argues in favor of long-term anticoagulant treatment when inflammatory bowel disease is active.

[Hepatic disorders related to Lyme disease. Study of two cases and a review of the literature]. / L'atteinte hépatique dans la maladie de Lyme. Etude de deux cas et revue de la littérature.

We report two cases of Lyme disease, revealed by hepatic damage in a 71- and a 59-year old man. In the first case, the disease was revealed by febrile jaundice whereas, in the second case, results of liver tests showed cytolytic and cholestatic abnormalities with fever. Lyme disease is a zoonosis due to infection by Borrelia burdorferi transmitted by ticks. The multiple phases of the disease explain the polymorphism of the clinical manifestations. Usually, extrahepatic symptoms are first observed, including neurological tropisms of Borrelia burdorferi. On the contrary, hepatic impairment due to Lyme disease is rare, often asymptomatic and with biological manifestations only.

Low sensitivity of invasive tests for the detection of Helicobacter pylori infection in patients with bleeding ulcer.

BACKGROUND: A high false negative rate for antral infection with Helicobacter pylori when assessed by rapid urease test has recently been reported in patients with bleeding ulcer. This result could partly explain the differing prevalence of H. pylori infection in bleeding and non-bleeding ulcers. AIMS: To evaluate the accuracy of a rapid urease test (UT), histology and culture for detection of H. pylori in antral biopsies from acute bleeding peptic ulcer patients using a serological test as reference. PATIENTS AND METHODS: All consecutive patients with active bleeding gastric or duodenal ulcer at endoscopic examination admitted in six university hospitals in France were considered for inclusion. Five antral biopsies were taken during the diagnostic endoscopy for UT, culture and histology. A blood sample was taken for H. pylori serology. RESULTS: One hundred and eighty one patients were included and 129 (71%) had a positive serology. The sensitivity of UT, histology and culture for detection of H. pylori infection were 41%, 33% and 34%, respectively. The sensitivity and specificity of the combination of the three invasive tests were 48.8% (95% CI: 40.2-57.4) and 90.6% (95% CI: 82. 6-99) respectively. In the 52 serologically negative patients, only 5 had at least one invasive positive test. The sensitivity of the invasive tests decreased significantly with age but was not influenced by NSAIDs intake. Of 80 patients with a positive serological test and negative histological evaluation for H. pylori, chronic antral inflammation was found in 70 patients (87%). In 46 patients with both negative serological test and H. pylori negative test according to histology, only 13 (28%) had chronic antral inflammation. CONCLUSIONS: The sensitivity of invasive tests for detection of H. pylori is low during acute ulcer bleeding, and they should be used with caution in this condition. A serological test is recommended to identify patients with H. pylori infection in spite of negative invasive tests.

[Adult idiopathic ductopenia. 1 case]. / Ductopénie idiopathique de l'adulte. Un cas.

Idiopathic adult ductopenia is very rare. We report one case in a 30-year-old man, whose clinical course was characterized by jaundice and pruritus. Laboratory investigations revealed cholestasis and polyclonal hypergammaglobulinemia. Serum antinuclear, antimitochondrial, and anti-smooth muscle antibodies and serological markers for viral hepatitis were negative. Endoscopic retrograde cholangiography showed no liver or biliary tract abnormalities. Histological examination of a liver specimen showed a vanishing bile duct syndrome and moderate portal infiltration with lympho-histiocytic cells; there were no granulomas. Liver transplantation was performed due to rapid development of cirrhosis. The differential diagnosis of idiopathic adult ductopenia with small duct primary sclerosing cholangitis, auto-immune cholangiopathy, and non syndromic paucity of intrahepatic bile ducts is unclear.

[Helicobacter pylori and gastroduodenal lesions in 547 symptomatic young adults]. / Helicobacter pylori et lésions gastro-duodénales chez 547 jeunes adultes symptomatiques.

OBJECTIVES: Helicobacter pylori (H. pylori) is involved in the pathogenesis of gastric inflammatory disorders. Both antral chronic gastritis and H. pylori infection prevalence increase with age. The aim of the study was to assess the prevalence of H. pylori infection in young adults and to study the relationship between endoscopical and histological features and H. pylori infection. METHODS: The study concerned 547 young patients (age: 18-25 years), undergoing endoscopy for upper gastrointestinal symptoms. The severity and the activity of chronic gastritis was graded by histological examination of antral biopsies. The diagnosis of H. pylori infection was based on histology and culture or urease test. RESULTS: Fifty-three percent of the patients had a normal endoscopy; 44 ulcers were found: 34 duodenal ulcers and 10 gastric ulcers. H. pylori infection was detected in 34% of cases. The prevalence of H. pylori infection was 29.8% in non-ulcer patients, 50% in gastric ulcers and 91% in duodenal ulcers (P < 0.01). Duodenal ulcer, aspect of antral mosaic mucosa and nodular gastritis, were closely related to the presence of H. pylori. There was a significant relationship between H. pylori infection and both the severity (P < 0.01) and the activity (P < 0.01) of the antral chronic gastritis. The prevalence of follicular gastritis was 22% : it was present in 60% of H. pylori positive patients and 2.4% of H. pylori negative patients. H. pylori infection was more frequent in patients from Africa than in Europeans (P < 0.01). There was no significant association between H. pylori infection and different types of diets, settlements (rural vs urban) or symptoms. CONCLUSION: These results show that in the young population studied, duodenal ulcer, nodular gastritis, antral mosaic mucosa, active chronic gastric and follicular gastritis are closely related to H. pylori infection. They suggest that in the subgroup of non ulcer symptomatic patients, H. pylori prevalence is higher than in the general population.

[Leiomyosarcoma of the small intestine presenting as an isolated lower digestive tract hemorrhage. Report of 2 cases]. / Léiomyosarcome du grêle révélé par une hémorragie digestive basse isolée. A propos de deux cas.

The authors report two cases of leiomyosarcoma of the small intestine revealed by lower and isolated digestive bleeding. In both cases, only the pelvic examinations by means of ultrasonography and/or CT scan have shown a mass which corresponded to the small intestine tumor. The authors underlined the necessity of US and/or CT scan pelvic when faced with a lower digestive bleeding whose etiology cannot be determined by the endoscopic or radiologic intestinal examinations.
