[Analysis of the effect of transgluteal percutaneous drainage in the treatment of deep pelvic abscess].

Objective: To investigate the safety and feasibility of transgluteal percutaneous drainage using double catheterization cannula in the treatment of deep pelvic abscess. Methods: A retrospective analysis of the clinical data of patients who underwent transgluteal percutaneous drainage using double catheterization cannula with deep pelvic abscesses admitted to the Jinling Hospital from May 2017 to September 2020 was conducted. Seven patients were enrolled, including 5 males and 2 females, who aged 26-74 (median 53.0) years old, and all of them had digestive fistula. One male patient was punctured again due to the tube falling off, and a total of 7 patients underwent 8 times of transgluteal percutaneous drainage, all under the guidance of CT. The puncture and drainage steps of the double catheterization cannula group are as follows: (1) Locate the puncture point under CT in the lateral position; (2) Place the trocar into the abscess cavity; (3) Confirm that the trocar is located in the abscess cavity under CT; (4) Pull out the inner core and insert into the double catheterization cannula through the operating hole; (5) Confirmthat the double catheterization cannula is located in the abscess cavity under CT; (6) The double catheterization cannula is properly fixed to prevent it from falling off. The white blood cells, C-reactive protein (CRP), procalcitonin, and interleukin-6 (IL-6) of all patients before the drainage and 1 days, 3 days, and 5 days after the drainage were collected, as well as the bacterial culture results of the drainage fluid. The changes of various infection biomarkers before and after the drainage were compared. Results: All 7 patients were cured. No complications such as hemorrhage and severe pain were observed. The average time with drainage tube was 60.8 (18-126) days. Five patients finally underwent gastrointestinal reconstruction surgery due to gastrointestinal fistula. The median serum interleukin-6 of patients before drainage, 1 day, 3 days and 5 days after drainage were 181.6 (113.0, 405.4) µg/L, 122.2 (55.8, 226.0) µg/L, 59.2 (29.0,203.5) µg/L and 64.1 (30.0,88.4) µg/L, respectively.The level of serum interleukin-6 at 3 days and 5 days after drainage was significantly lower than before drainage (F=3.586, P=0.026). Although the white blood cell count, C-reactive protein, and procalcitonin decreased gradually after drainage compared with before drainage, the difference was not statistically significant (all P>0.05). Conclusion: Transgluteal percutaneous drainage with double catheterization cannula is simple and effective, and can be used for the treatment of deep pelvic abscess.

[Efficacy of continuous irrigation combined with closed thoracic drainage for esophagojejunal anastomotic fistula complicated with mediastinal, thoracic and abdominal infections].

OBJECTIVE: To investigate the clinical efficacy of continuous irrigation combined with closed thoracic drainage for esophagojejunal anastomotic fistula (EJAF) complicated with mediastinal, thoracic and abdominal infection after total gastrectomy. METHODS: Clinical data of 22 EJAF patients complicated with mediastinal, thoracic and abdominal infection after radical gastrectomy at Department of General Surgery of the 901th Hospital of PLA from June 2012 to May 2018 were retrospectively analyzed. Case inclusion criteria:(1) gastric adenocarcinoma confirmed by preoperative endoscopic pathology undergoing radical total gastrectomy without severe organ dysfunction;(2)EJAF complicated with mediastinal, thoracic and abdominal infections diagnosed by postoperative radiography, the presence of pleural effusion confirmed by CT and ultrasound. Among them, 10 cases were treated with simple thoracic closed drainage (single drainage group); 12 cases received same closed thoracic drainage, and a rubber catheter was placed next to the closed thoracic drainage tube in the same sinus. A 0.9% sodium chloride solution was applied in continuous drip irrigation with drip velocity at 50 to 100 ml/h(continuous flushing plus drainage group). Infection indicators, anastomotic fistula healing time and related clinical indicators were compared between the two groups. RESULTS: In the simple drainage group, 5 cases were males, age was (61.9±10.7) years old, 4 cases received laparoscopic surgery, 6 cases received open surgery, 6 cases were EJAF grade III, 4 cases were EJAF IV. In continuous flushing and drainage group, 6 cases were males, age was (61.7±11.0) years old, 7 cases received laparoscopic surgery, 5 cases received open surgery, 6 cases were EJAF grade III, and 6 cases were EJAF grade IV. Baseline data including gender, age, underlying diseases, preoperative hematological examination indexes, surgical methods, tumor TNM stage and EJAF grade were not significantly different between the two groups (all P>0.05). When postoperative EJAF was complicated with mediastinal, thoracic and abdominal infection, biochemical parameters including white blood cell, procalcitonin, C-reactive protein were not significantly different between two groups (all P>0.05). All patients of both groups achieved clinical cure without death. Compared with the simple drainage group after closed thoracic drainage, the continuous irrigation plus drainage group had significantly shorter duration of infection parameters returning to normal levels [white blood cell count: (6.8 ± 2.0) days vs.(10.5±3.0) days, t=4.062, P<0.001; procalcitonin: (7.5±1.0) days vs. (9.2±1.9) days, t=3.236, P=0.040; C-reactive protein: (8.8±1.0) days vs. (11.2±1.5) days, t=5.177, P<0.001], meanwhile time in surgical ICU [(4.9±2.5) days vs. (9.9±6.7) days, t=2.935, P=0.006], healing time of fistula [(42.9±12.5) days vs. (101.8±53.2) days, t=4.187, P=0.001] and total postoperative hospital stay [(62.3±15.8) days vs. (119.7 ±59.4) days, t=3.634, P=0.002] were significantly shorter, and total hospitalization cost was significantly lower (median 86 000 yuan vs. 124 000 yuan, Z=2.063, P=0.040) in the continuous irrigation plus drainage group. CONCLUSION: The continuous closed thoracic drainage with 0.9% sodium chloride solution can accelerate infection control and remission of EJAF patients complicated with mediastinal, thoracic and abdominal infections, and shorten the healing time of anastomotic fistula.

[A woman with fever and a painful hip]. / Een vrouw met koorts en een pijnlijke heup.

An immunocompromised 78-year-old woman had a painful hip and subacute fever. An abdominal CT scan revealed a diverticular sigmoid stenosis fistulating to the presacral space, with free gas in the paravertebral musculature and spinal canal. Because a deep necrotising infection was suspected, she underwent surgery and was treated with antibiotics. She recovered completely.

Spontaneous right hepatic artery branch gallbladder fistula revealed by haemobilia and upper cataclysmic gastrointestinal bleeding.

Spontaneous right hepatic artery branch gallbladder fistula is a rare condition. Our case reported a spontaneous fistula between the right branch of the hepatic artery and the gall bladder. It constitutes a rare cause of haemobilia. In fact, the most common aetiology of haemobilia is traumatic or iatrogenic secondary to hepatobiliary surgery or interventions. Diagnosis of vascular-biliary fistula is not easy. The gallbladder endoluminal clot can mimic a mass, as in our patient. Selective arterial angiography is helpful in identifying the source of gastrointestinal haemorrhage. It can demonstrate the presence of arteriobiliary fistula. The differential diagnosis is arterial pseudoaneurysm in the vicinity of the vessel. Mini-invasive treatment of this fistula constitutes the best treatment. We here report a case of haemobilia with upper cataclysmic gastrointestinal bleeding revealing a spontaneous fistula between the right branch of the hepatic artery and the gall bladder.

Shifting trends in bacteriology and antimicrobial resistance among gastrointestinal fistula patients in China: an eight-year review in a tertiary-care hospital.

BACKGROUND: The purpose of this study was to determine the shifting trends in bacteriology and antimicrobial resistance of infectious specimens isolated from gastrointestinal (GI) fistula patients over eight years in China. METHODS: We retrospectively reviewed the microbial records of intra-abdominal specimens at a teaching hospital from 2008 to 2015. Study period was divided into the first half (2008-2011) and the second half (2012-2015). All isolates underwent antibiotic susceptibility testing by the micro dilution method. RESULTS: A total of 874 intra-abdominal isolates were consecutively collected from 502 GI fistula patients (mean age, 46.5 years, 71.1% male) during the study period. Patients in the second study period (2012-2015) were older (>65 years) and more likely to have experienced cancer. Over the entire study period, most infections were caused by E. coli (24.2%) and K. pneumonia (14.1%). There was a significant decrease in the proportion E. coli isolates that were extended- spectrum beta-lactamase (ESBL)-positive (P = 0.026). The proportion of E. coli resistant to imipenem increased from 14.3% in 2008-2011 to 25.9% in 2012-2015 (P = 0.037). Imipenem resistance prevalence was higher in ESBL-negative bacteria than ESBL-positive bacteria for both E. coli and K. pneumonia (P < 0.001). In Enterococcus, significant increase in resistance to ampicillin (P = 0.01) and moxifloxacin (P = 0.02) over time were observed. In Staphylococcus and fungi, rates of antibiotic resistance did not significantly change over the study period. CONCLUSIONS: Gram-negative bacteria predominated as causative agents of intra-abdominal infections in GI fistula patients, and there was an increase in levels of resistance to certain antibiotics, particularly carbapenems. Infection control and source control are important tools available to surgeons to prevent the emergence of antibiotic-resistant pathogens.

Coloduodenal and enterocutaneous fistula in twins with Crohn´s disease.

We present the case of a pair of 45-year-old monozygotic twins (A and B) diagnosed with Crohn's disease (CD) at age 20 (A) and 22 (B) with similar presenting symptoms: diarrhea, fever and weight loss. Both of them had duodenal and ileocolonic disease (A2, L3+L4 according to Montreal classification); twin B also presented jejunal involvement and perianal disease (B1p). They received treatment with antibiotics, corticosteroids, 5-ASA, azathioprine and anti-TNF with a poor control of activity. They both developed a coloduodenal fistula that required surgery. Twin A developed the fistula 12 years after the first presentation; fistula closure with duodenorraphy and ileocolonic resection with gastrojejunostomy was performed. Twin B developed the fistula 22 years after the first presentation, and right colectomy, partial duodenectomy and duodenorraphy was carried out. Both developed an enterocutaneous fistula during the postoperative period. With intensive medical treatment, both twins remain asymptomatic.

[Efficacy of over-the-scope clip for gastrointestinal fistula].

OBJECTIVE: To explore the efficacy of over-the-scope clip (OTSC) in the treatment of gastrointestinal fistula. METHODS: Clinical data of 12 gastrointestinal fistula patients, including 3 internal fistula and 9 external fistula treated with OTSC in our institute from March 2015 to May 2016 were retrospectively analyzed. OTSC was performed when pus was drained thoroughly and intra-abdominal infection around gastrointestinal fistula was controlled, and each patient received one clip to close fistula. RESULTS: There were 6 female and 6 male patients with mean age of (50.1±12.6) years. The successful rate of endoscopic closure was 100% without complications including bleeding and intestinal obstruction during and after OTSC treatment. According to comprehensive evaluation, including drainage without digestive juices, no recurrence of intra-abdominal infection, no overflow of contrast medium during digestive tract radiography, and CT examination without intra-abdominal abscess, clinical gastrointestinal fistula closure was 91.7%(11/12). There was no recurrence of gastrointestinal fistula during 3 months of follow-up in 11 patients. In the remaining 1 case, the gastric fistula after laparoscopic sleeve gastrectomy recurred one week after OTSC treatment because of intra-abdominal infection surrounding fistula, and was cured by surgery finally. CONCLUSION: The endoscopic closure treatment of OTSC for gastrointestinal fistula is successful and effective, and control of intra-abdominal infection around fistula with adequate drainage is the key point.

Pyopneumothorax and peritonitis due to perforated duodenal ulcer and associated pleuroperitoneal communication.

Pleuroperitoneal communication is an anatomic entity that is typically asymptomatic but sometimes responsible for hydrothorax. This pleural manifestation can be explained by progressive transdiaphragmatic passage of intra-abdominal fluid because of abdominal hyperpressure. The object of this report is to present a hitherto unreported association of concomitant pleural effusion and acute infectious abdominal disease, due to perforated duodenal ulcer. This underscores that pleural effusion associated with acute abdominal pain may reveal the existence of a communication of this type, and requires surgical management.

THE OVER-THE-SCOPE-CLIP FOR THE TREATMENT OF THE DIGESTIVE TUBE LEAKS AND TEARS: A CASE-SERIES. / LIJECENJE OSTECENJA PROBAVNE CIJEVI PRIMJENOM ENDOSKOPSKE STEZALJKE: PRIKAZ SERIJE BOLESNIKA.

Digestive tube damages represent a therapeutic challenge for the gastrointestinal endoscopists. Recenty, a novel device ­ the-over-the-scope clip (OTSC) ­ has been introduced for non-surgical treatment of gastrointestinal perforations, fi stula, anastomotic leaks and refractory gastrointestinal bleeds. This study aimed to evaluate the therapeutic effi cacy of OTSC in our case series. A total of nine patients were included (six males, medain age 72 years, range 58-86). The indications were upper gastrointestinal bleeding (refractory to standard endoscopic treatment: fi ve patients, a vessel with a large caliber: one patient), fi stula in two patients, and iatrogenic perforation of the sigmoid colon in one patient. Atraumatic and traumatic versions of OTSCs with twin graspers were used. All of the patients were treated with only one OTSC, and none of the patients required additional endoscopic treatment. The OTSC procedure had 100% technical success. In a subgroup of patients with perforation and fi stulae, the clinical success was 67%, whereas in those with the bleedings it was 50%. The median follow-up was 34 days (range: 3-452). OTSC is a safe and effective device for closure of perforations and leaks. However therapeutic effi cacy was subopimal in patients with the upper gastrointestinal bleedings possibly due to the application of the sharp-teeth OTSC.

CT and MR imaging features of fistulas from intraductal papillary mucinous neoplasms of the pancreas to adjacent organs: A retrospective study of 423 patients.

PURPOSE: The objectives of this study were to determine the frequency with which intraductal papillary mucinous pancreatic neoplasms (IPMNs) show fistulization to adjacent organs and to describe the multidetector row computed tomography (MDCT) and magnetic resonance imaging (MRI) findings for this specific complication. METHODS: A retrospective analysis of the clinical and imaging files of all patients with IPMNs who were followed over 8 years by our department was performed to identify those with fistula formation. Two radiologists determined the type of IPMN, the number and size of visible fistulas, the involved adjacent organs, the pancreatic location and the presence of imaging findings suggestive of malignant transformation of the IPMN. Histological correlation was also performed. RESULTS: A total of 423 patients were included. Fistula formation was present in 8 patients (1.9%). The corresponding IPMNs were of the main duct type (n=4; 50%), the branch duct type (n=1; 13%) or the mixed type (n=3; 38%). In half of the cases, these tumors were discovered incidentally. A total of 26 fistulas (1-7 per patient) were identified. These fistulas involved the duodenum (65.4%), stomach (19.2%), common bile duct (11.5%) and colon (3.8%). All patients had fistulas to the duodenum. All fistulas appeared to develop from a malignant IPMN based on the imaging studies, but two of the five available samples did not exhibit atypia (a quarter of all fistulas). In 50% of cases, the IPMN was of the intestinal form. CONCLUSIONS: Fistulas are uncommon complications of IPMNs, regardless of malignant transformation of the IPMNs. Fistulas appear to predominate among malignant main-duct IPMNs, are generally multiple and affect several organs, and their preferential target is the duodenum. However, fistulas do not adhere to a strict criterion of malignancy.

Uso do retalho microcirúrgico anterolateral da coxa na correção de fístula esôfago-cutânea / Use of the microsurgical anterolateral thigh flap to correct esophagocutaneous fistula

INTRODUÇÃO: O retalho anterolateral da coxa (RALC) vem se tornando uma ferramenta importante na reconstrução microcirúrgica de defeitos cutâneos e subcutâneos. Tendo em vista que o RALC pode se estender por até 35 cm, ele pode ser utilizado tanto na reconstrução esofágica como em defeitos cutâneos cervicais. RELATO DO CASO: Paciente C.S.M., sexo feminino, 57 anos, apresentando um carcinoma espinocelular de laringe foi submetida à radioterapia e tratamento cirúrgico de laringectomia total seguido de reconstrução por fechamento primário. Porém, a paciente evoluiu com uma complicação pósoperatória devido à formação de uma fístula esôfago-cutânea cervical, sendo necessária a realização de 4 procedimentos cirúrgicos para fechamento definitivo da fístula. O último procedimento consistiu na realização de retalho microcirúrgico da região anterolateral da coxa para correção da fístula esôfago-cutânea, objeto desse relato. CONCLUSÕES: O retalho microcirúrgico anterolateral da coxa possui extensa aplicação em diversos campos, baseada nas seguintes características: vascularização confiável, pedículo vascular longo e largo de no mínimo 8 cm, região do retalho extensa e de fácil delimitação, possibilidade de diminuir a espessura primária do retalho em 3 a 5 mm sem risco de comprometer sua vascularização, possibilidade de abordagem dupla simultânea devido à distância entre sítio doador e receptor, possibilidade de fechamento primário sem a necessidade de enxerto de pele. O relato do caso apresentado neste estudo justifica-se com o intuito de ressaltar a possibilidade da utilização microcirúrgica do RALC em sanduíche na correção de fístula esôfago-cutânea de alto débito.

INTRODUCTION: The anterolateral thigh (ALT) flap has become an important tool in the microsurgical reconstruction of cutaneous and subcutaneous defects. Since the ALT flap can be up to 35 cm long, it can be used in both, esophageal reconstruction and cervical skin defects. CASE REPORT: Patient C. S. M., a 57-year-old woman, presented with squamous cell carcinoma of the larynx and underwent radiotherapy and a total laryngectomy followed by reconstruction by primary closure. However, she developed a postoperative complication due to the formation of a cervical esophagocutaneous fistula that required four surgical procedures to ensure permanent closure. The latter procedure consisted of the creation of a microsurgical ALT flap to correct the esophagocutaneous fistula, the subject of this report. CONCLUSIONS: The microsurgical ALT flap has extensive applications in various fields based on the following characteristics: reliable vascularization, long and broad vascular pedicle (at least 8 cm long), an extensive and easily delimited flap region, the possibility of reducing the primary flap thickness to 3-5 mm without compromising its vascularization, the possibility of a simultaneously dual approach because of the distance between the donor and recipient site, and the possibility of primary closure without the need for skin grafting. The case report presented in this study emphasizes the possibility of the use of a microsurgical ALT sandwich flap to correct a high output esophagocutaneous fistula.

Complex partial status epilepticus in a patient with Crohn's disease.

Few cases of Crohn's disease complicated with meningitis and epidural abscess have been described in literature. We present a case of a 42-year-old former smoker female patient diagnosed with Crohn's disease in September 1995 (with severe nutritional problems). On 20 February 2012, she was admitted due to a probable sepsis (without any previous treatment). After several days she developed a confusion syndrome (probable Wernicke's disease). On 5 March 2012, the patient presented with a febrile episode of 39 ° C. Two days later, the patient presented aphasia and paraparesis, and 3 days later she presented a complex partial status epilepticus. A lumbar puncture was performed and showed 131 leucocytes (63% granulocytes) and proteins 296.3. The abdominopelvic CT scan revealed a presacral collection that seem to extend cranially towards the lumbosacral spine. The lumbar MRI confirmed the lumbar epidural abscess secondary to the fistulisation of the presacral abscess.

Efficacy and safety of over-the-scope clip: including complications after endoscopic submucosal dissection.

AIM: To retrospectively review the results of over-the-scope clip (OTSC) use in our hospital and to examine the feasibility of using the OTSC to treat perforations after endoscopic submucosal dissection (ESD). METHODS: We enrolled 23 patients who presented with gastrointestinal (GI) bleeding, fistulae and perforations and were treated with OTSCs (Ovesco Endoscopy GmbH, Tuebingen, Germany) between November 2011 and September 2012. Maximum lesion size was defined as lesion diameter. The number of OTSCs to be used per patient was not decided until the lesion was completely closed. We used a twin grasper (Ovesco Endoscopy GmbH, Tuebingen, Germany) as a grasping device for all the patients. A 9 mm OTSC was chosen for use in the esophagus and colon, and a 10 mm device was used for the stomach, duodenum and rectum. The overall success rate and complications were evaluated, with a particular emphasis on patients who had undergone ESD due to adenocarcinoma. In technical successful cases we included not only complete closing by using OTSCs, but also partial closing where complete closure with OTSCs is almost difficult. In overall clinical successful cases we included only complete closing by using only OTSCs perfectly. All the OTSCs were placed by 2 experienced endoscopists. The sites closed after ESD included not only the perforation site but also all defective ulcers sites. RESULTS: A total of 23 patients [mean age 77 years (range 64-98 years)] underwent OTSC placement during the study period. The indications for OTSC placement were GI bleeding (n = 9), perforation (n = 10), fistula (n = 4) and the prevention of post-ESD duodenal artificial ulcer perforation (n = 1). One patient had a perforation caused by a glycerin enema, after which a fistula formed. Lesion closure using the OTSC alone was successful in 19 out of 23 patients, and overall success rate was 82.6%. A large lesion size (greater than 20 mm) and a delayed diagnosis (more than 1 wk) were the major contributing factors for the overall unsuccessful clinical cases. The location of the unsuccessful lesion was in the stomach. The median operation time in the successful cases was 18 min, and the average observation time was 67 d. During the observation period, none of the patients experienced any complications associated with OTSC placement. In addition, we successfully used the OTSC to close the perforation site after ESD in 6 patients. This was a single-center, retrospective study with a small sample size. CONCLUSION: The OTSC is effective for treating GI bleeding, fistulae as well as perforations, and the OTSC technique proofed effective treatment for perforation after ESD.

Endoscopic management of hepatic hydatid cyst with biliary communication.

BACKGROUND AND AIM: A serious complication of hepatic hydatid cyst disease is communication between the cyst and the biliary tree. Surgical management of biliary fistulas is associated with high morbidity and mortality. We carried out a prospective study of endoscopic management of hydatid cysts communicating with bile ducts in 28 patients. METHODS: Presence of biliary fistula was suspected by jaundice and/or persistent external biliary fistula after surgical excision and was confirmed by endoscopic retrograde cholangiopancreatography (ERCP). Patients underwent endoscopic sphincterotomy, and either biliary stenting or nasobiliary drainage. Nasobiliary drains were removed when bile leakage stopped and closure of the fistula was confirmed by cholangiography; stents were removed after 4-6 weeks. RESULTS: Of 120 patients with hepatic hydatid cyst seen over a 10-year period, 28 patients developed fistula between the hepatic hydatid cyst and intrahepatic bile ducts (right intrahepatic bile ducts in 20 patients, left intrahepatic bile ducts in eight patients). Nine of 28 patients had persistent external biliary fistula after surgery. Ten patients showed membranes in bile ducts on cholangiography. We carried out either sphincterotomy with insertion of a nasobiliary drain (n=6) or sphincterotomy with biliary stenting (n=22). In 10 patients, the membranes were removed from bile ducts during ERCP. Fistulas healed in all patients after a median time of 11 days (range 5-45 days) after endoscopic treatment. We were able to remove nasobiliary drainage catheters and stents 8-45 days after placement. CONCLUSIONS: Endoscopic therapy is an effective mode of treatment for biliary fistulas complicating hepatic hydatid cyst.

Perianal Crohn's disease findings other than fistulas in a population-based cohort.

BACKGROUND: The cumulative incidence of and risk factors for perianal Crohn's disease (CD) for findings other than fistulas are unknown. METHODS: The medical records of 310 incident cases of CD from Olmsted County, Minnesota, diagnosed between 1970 and 2004, were reviewed for evidence of perianal disease findings other than fistulas. Cumulative incidence was estimated using the Kaplan-Meier method, and associations between baseline factors and time to first event were assessed using proportional hazards regression. Four types of lesions were studied: anorectal strictures, deep anal canal ulcers, anal fissures, and perianal skin tags. RESULTS: The 10-year cumulative probability from time of diagnosis was 5.8% (95% confidence interval [CI], 2.6%-8.8%) for anorectal strictures, 6.6% (3.6%-9.6%) for deep anal canal ulcers, 10.5% (6.8%-14.1%) for anal fissures, and 18.7% (13.9%-23.3%) for perianal skin tags. The cumulative probability for any perianal lesion other than fistulas was 21.3% (16.5%-25.8%) at 5 years and 29.2% (23.5%-34.5%) at 10 years. Baseline factors associated with time to first perianal lesion other than fistulas were age (hazard ratio [HR] per 10 years, 0.9; 95% CI, 0.8-0.98; P = 0.026), female gender (HR, 1.7; 95% CI, 1.1-2.7; P = 0.013), and presence of extraintestinal manifestations (HR, 1.7; 95% CI, 1.03-2.8; P = 0.038). CONCLUSIONS: Perianal lesions other than fistulas occurred frequently during the clinical course of CD. Female gender and extraintestinal manifestations were associated with increased risks for perianal lesions other than fistulas, while older age at diagnosis was associated with a slightly decreased risk.
