A flow restrictor implanted percutaneously across a loose pulmonary artery band

Pulmonary artery banding usually is performed as a palliative procedure. In patients with elevated pulmonary vascular resistance and complex congenital heart disease, it may not be possible at the time of surgery to obtain sufficient restriction to optimize the patient for further treatment; additional restriction may be needed in time. We present a technique where we used a combination of two devices (a 10‐mm Amplatzer ASD occluder fenestrated with a Palmaz Genesis 9/19 mm stent) to percutaneously further reduce the flow to the lungs 1 month after surgical placement of a pulmonary artery band in a 16‐year‐old girl with complex univentricular heart. Eight months after the banding the patient successfully underwent completion of the Fontan circulation by total cavopulmonary connection. This technique allows to reduce flow without redo surgery. In well‐selected patients, this new percutaneous technique allows to better prepare such complex patients for future surgery. © 2011 Wiley‐Liss, Inc.

Multiple Perforations along the Entire Colon as a Complication of Intestinal Behcet's Disease: A Rare Case

Colonic complications of Behcet''s disease due to intestinal involvement are rarely reported in the literature. Ulcers are the most frequently seen intestinal complications that cause bleeding and perforation predominantly in the ileocecal region. In this article, we report a patient with Behcet''s disease who presented with multiple perforations along the entire colon. Postoperative histopathological examination revealed multiple ulcers containing lymphocytic infiltrations in the small peripheral and submucosal venules. Intimal thickening and fresh intraluminal fibrin thrombosis were also seen in these venules.     

Use of accurate diagnostic criteria may increase incidence of stercoral perforation of the colon

PURPOSE: Stercoral perforation of the colon is reported to be a rare disease with poor prognosis. The aim of this study was to determine the frequency of stercoral perforation of the colon, to define diagnostic criteria for stercoral perforation of the colon, and to analyze the patient outcome in a university hospital gastrointestinal surgery unit. METHODS: From November 1993 until November 1998 all surgically treated patients with a colorectal disease were prospectively recorded in a computerized database. Diagnosis of stercoral perforation of the colon was made if 1) the colonic perforation was round or ovoid, exceeded 1 cm in diameter, and lay antimesenteric; 2) fecalomas were present within the colon, protruding through the perforation site or lying within the abdominal cavity; and 3) pressure necrosis or ulcer and chronic inflammatory reaction around the perforation site were present microscopically. Any additional colon pathology led to exclusion from the diagnosis of stercoral perforation of the colon. Using the same criteria, 81 cases in the literature were found to qualify and were further analyzed. RESULTS: In a five-year period 1,295 patients underwent colorectal interventions through laparotomy. A total of 566 (44 percent) cases were emergencies, 220 (17 percent) of these caused by colonic perforation. Seven patients had stercoral perforation of the colon. The incidence of stercoral perforation of the colon was 0.5 percent of all surgical colorectal procedures through laparotomy, 1.2 percent of all emergency colorectal procedures, and 3.2 percent of all colonic perforations. The mean age of the patients was 59 (median, 64; range, 22–85) years. All perforations were situated in the left hemicolon or upper rectum. The round or ovoid perforation had a mean diameter of 3.6 cm. Fecalomas were present in all patients and protruded from the perforation site or were found within the free abdominal cavity in three of them. Generalized stercoral peritonitis was a constant finding. Using a colonic resection without immediate restoration of continuity, an extensive intraoperative lavage, and antibiotics, there was no in-hospital mortality. Analysis of the reports in the literature revealed additionally that 28 percent of patients with stercoral perforation of the colon have multiple stercoral ulcers in the colon and that substantial mortality is encountered if only minor surgical procedures of treatment are used. CONCLUSIONS: The incidence of stercoral perforation of the colon seemed to have been underestimated. The reason for this might be the lack of defined diagnostic criteria for this disease. Low mortality is obtained by early surgical eradication of the affected part of the colon, including all stercoral ulcers, and by aggressive therapy for peritonitis.Presented in part at the meeting of the Swiss Society of Surgery, Lugano, Switzerland, June 9 to 12, 1999.     

Gastrointestinal perforation secondary to COVID-19: Case reports and literature review

Introduction:Corona virus disease-2019 (COVID-19) presents primarily with respiratory symptoms. However, extra respiratory manifestations are being frequently recognized including gastrointestinal involvement. The most common gastrointestinal symptoms are nausea, vomiting, diarrhoea and abdominal pain. Gastrointestinal perforation in association with COVID-19 is rarely reported in the literature.Patient concerns and diagnosis:In this series, we are reporting 3 cases with different presentations of gastrointestinal perforation in the setting of COVID-19. Two patients were admitted with critical COVID-19 pneumonia, both required intensive care, intubation and mechanical ventilation. The first one was an elderly gentleman who had difficult weaning from mechanical ventilation and required tracheostomy. During his stay in intensive care unit, he developed Candidemia without clear source. After transfer to the ward, he developed lower gastrointestinal bleeding and found by imaging to have sealed perforated cecal mass with radiological signs of peritonitis. The second one was an obese young gentleman who was found incidentally to have air under diaphragm. Computed tomography showed severe pneumoperitoneum with cecal and gastric wall perforation. The third case was an elderly gentleman who presented with severe COVID-19 pneumonia along with symptoms and signs of acute abdomen who was confirmed by imaging to have sigmoid diverticulitis with perforation and abscess collection.Interventions:The first 2 cases were treated conservatively. The third one was treated surgically.Outcome:Our cases had a variable hospital course but fortunately all were discharged in a good clinical condition.Conclusion:Our aim from this series is to highlight this fatal complication to clinicians in order to enrich our understanding of this pandemic and as a result improve patients’ outcome.     

Delta neutrophil index and symptomatic time are effective factors for predicting perforated appendicitis

Appendicitis is a common intra-abdominal inflammatory disease, and morbidity increases with age when perforation occurs. Because, not all patients require emergency surgery, there have been numerous studies on factors for predicting perforated appendicitis. In this study, we aimed to confirm whether the delta neutrophil index (DNI) and the time from symptom onset to surgery are effective predictors for perforated appendicitis in different age groups.This was a retrospective study conducted on 542 appendicitis patients who underwent surgery at Kangdong Sacred Heart Hospital. The simple group consisted of 431 subjects, and the perforation group consisted of 111 subjects.Multiple logistic regression analyses demonstrated that age, neutrophil percentage, DNI, C-reactive protein (CRP), and symptomatic time were significant predictors of perforation. Analysis of the receiver-operating characteristic curve showed that the DNI was the most reliable predictive value. In the analyses according to age, the perforation rate was higher in the >65-year-age group; these patients also had a higher DNI, CRP, and symptomatic time. In the DNI analysis using receiver operating characteristic (ROC) analysis, the area under the curve was higher in the >65-year-age group than in other age groups. In addition, the cutoff values have been determined and perforation occurred significantly in the group with a DNI value of 2.1 or higher and a symptomatic time of 33 hours or longer.DNI is effective in predicting perforation in patients with appendicitis compared with other inflammatory factors. Furthermore, the simultaneous measurement of symptomatic time and DNI is helpful in predicting perforation and determining whether emergency surgery is necessary.     

Current treatment and outcome of esophageal perforation: A single-center experience and a pooled analysis

Background:Esophageal perforation has been one of the serious clinical emergencies, because of the high mortality and complication rates. However, the current prognosis of esophageal perforation and the outcomes of available treatment methods are not well defined. This study attempted to pool the immediate outcomes of esophageal perforation in the past 2 decades.Methods:The clinical data of 22 consecutive adult patients with esophageal perforation in our center were analyzed. A pooled analysis was also conducted to summarize results from the literatures published between 1999 and 2020. Studies that met the inclusion criteria were assessed, and their methodological quality was examined.Results:The mortality and complication rates in our center were 4.55% and 31.82%, separately. The pooled analysis included 45 studies published between 1999 and 2019, which highlighted an overall immediate mortality rate of 9.86%. Surgical treatments were associated with a pooled immediate mortality of 10.01%, and for conservative treatments of 6.49%. Besides, in the past decade, the mortality and complication rates decreased by 27.12% and 46.75%, respectively.Conclusions:In the past 2 decades, the overall immediate mortality rate of esophageal perforation was about 10% in the worldwide, and the outcomes of esophageal perforation treatment are getting better in the last 10 years.Ethics Registration Information:LW2020011.
