[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.

Open abdomen treatment for complicated intra-abdominal infection patients with gastrointestinal fistula can reduce the mortality.

To evaluate the effect of the open abdomen (OA) and closed abdomen (CA) approaches for treating intestinal fistula with complicated intra-abdominal infection (IFWCIAI), and analyze the risk factors in OA treatment.IFWCIAI is associated with high mortality rates and healthcare costs, as well as longer postoperative hospital stay. However, OA treatment has also been linked with increased mortality and development of secondary intestinal fistula.A total of 195 IFWCIAI patients who were operated over a period of 7 years at our hospital were retrospectively analyzed. These patients were divided into the OA group (n = 112) and CA group (n = 83) accordingly, and the mortality rates, hospital costs, and hospital stay duration of both groups were compared. In addition, the risk factors in OA treatment were also analyzed.OA resulted in significantly lower mortality rates (9.8% vs 30.1%, P < .001) and hospital costs ($11721.40 ±â€Š$9368.86 vs $20365.36 ±â€Š$21789.06, P < .001) compared with the CA group. No incidences of secondary intestinal fistula was recorded and the duration of hospital stay was similar for both groups (P = .151). Delayed OA was an independent risk factor of death following OA treatment (hazard ratio [HR] = 1.316; 95% confidence interval [CI] = 1.068-1.623, P = .010), whereas early enteral nutrition (EN) exceeding 666.67 mL was a protective factor (HR = 0.996; 95% CI = 0.993-0.999, P = .018). In addition, Acinetobacter baumannii, Pseudomonas aeruginosa, and Candida albicans were the main pathogens responsible for the death of patients after OA treatment.OA decreased mortality rates and hospital costs of IFWCIAI patients, and did not lead to any secondary fistulas. Early OA and EN also reduced mortality rates.

[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.

Rare Case of Cerebrospinal Fluid Proctorrhea Caused by Anterior Sacral Meningocele with Rectothecal Fistula.

BACKGROUND: Anterior sacral meningocele (ASM) leading to secondary rectothecal fistula is extremely rare, and to date only 5 such cases have been described in the world literature. CASE DESCRIPTION: We describe an uncomplicated case of a 52-year-old female patient presenting with cerebrospinal fluid leak from the anus who was investigated and found to have an ASM with rectothecal fistula. The ASM and rectothecal fistula were subsequently repaired using a posterior approach. Pertinent literature review, clinical findings, neuroimaging, and surgical management are described for these rare lesions. CONCLUSION: Early diagnosis and surgical disconnection of the fistulous tract led to satisfactory outcome in the present case and avoided the catastrophic complication of meningitis.

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.

Diagnostic Accuracy of Sonography for Detection of a Fistula on the Birth Day in Neonates With an Imperforate Anus: Comparison of Diagnostic Performance Between Suprapubic and Perineal Approaches.

OBJECTIVES: To evaluate the diagnostic accuracy of sonography for detection of an internal fistula on the birth day in neonates with an imperforate anus and to compare the diagnostic performance between the suprapubic and perineal approaches. METHODS: We included 46 neonates with an imperforate anus (29 low type and 17 intermediate/high type) who underwent sonography by both the suprapubic and perineal approaches on the birth day. Thirty-nine neonates had internal fistulas, and 12 did not, as surgically proven. Two blinded radiologists evaluated the suprapubic and perineal sonograms for the presence of the internal fistula in consensus. A final diagnosis of the internal fistula was determined on the basis of the findings of both approaches. A receiver operating characteristic analysis was used to compare the diagnostic performance for detection of an internal fistula between the suprapubic and perineal approaches. RESULTS: The sensitivity, specificity, and accuracy of the final diagnosis based on the findings of suprapubic, perineal, and both approaches were 52.9%, 79.4%, and 79.4%; 75.5%, 75.5%, and 75.5%; and 58.7%, 78.3%, and 78.3%, respectively. The diagnostic performance of the perineal approach was significantly better than that of the suprapubic approach (P < .0001). CONCLUSIONS: The diagnostic accuracy of sonography for detection of an internal fistula on the birth day exceeded 75% in neonates with an imperforate anus, and sonography on the birth day is feasible. The perineal approach had superior diagnostic performance over the suprapubic approach. Thus, when evaluating an internal fistula by sonography, we recommend using the perineal approach in addition to the suprapubic approach.

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.

Dynamics of albumin synthetic response to intra-abdominal abscess in patients with gastrointestinal fistula.

BACKGROUND: Low serum albumin concentration is a predictor of failure of source control for intra-abdominal infection. However, data on dynamics of albumin synthesis in these patients and to what extent these changes contribute to hypoalbuminemia are relatively scarce. We investigated in a group of patients with gastrointestinal fistula the dynamic response of liver albumin synthesis to intra-abdominal abscess and how these related to hypoalbuminemia and circulating endocrine hormone profiles. METHODS: Eight gastrointestinal fistula patients scheduled to undergo percutaneous abscess sump drainage were enrolled prospectively to measure albumin synthesis rates at different stages of the inflammatory response (immediately after diagnosis and 7 d following sump drainage when clinical signs of intra-abdominal sepsis had been eradicated). Eight age-, sex-, and body mass index-matched intestinal fistula patients were studied as control patients. Consecutive arterial blood samples were drawn during a primed-constant infusion (priming dose: 4 micromol·kg(-1), infusion rate: 6 micromol·kg(-1)·min(-1)) to determine the incorporation rate of L-[ring-(2)H5]-phenylalanine directly into plasma albumin using gas chromatography/mass spectrometry analysis. RESULTS: Patients suffering from intra-abdominal infection had reduced plasma albumin and total plasma protein concentrations, compared with control patients. Albumin fractional synthesis rates in patients with intra-abdominal abscess were decreased, compared with those in the control group. When the source of infection was removed, albumin synthesis rates returned to control values, whereas albumin concentrations did not differ significantly from the corresponding concentrations in control subjects and patients with intra-abdominal abscess. CONCLUSION: Despite nutritional intervention, albumin synthesis rate is decreased in intestinal fistula patients with intra-abdominal abscess; albumin synthesis returns to control values during convalescence.
