Perforated Stress Ulcer of the Duodenum: a Case of an Unexpected Diagnosis in a COVID-19 Patient Following Dilatation and Curettage Procedure.

Background: Stress ulcers in the upper gastrointestinal tract can arise from pathologies related to erosive or inflammatory insults in critically ill patients. The relationship between stressful bodily events and the ischemia and perforation of stress ulcers is poorly understood. Objective: We present a case of perforated stress ulcer following an abortion that was treated by dilatation and curettage (D&C) and complicated by a coronavirus disease 2019 (COVID-19) infection. Case presentation: A 40-year-old lady presented to the emergency room complaining of diffuse abdominal pain, she was recently diagnosed with an incomplete abortion and managed via a D&C procedure in an external hospital. A computed tomography (CT) scan was done at our center for the abdomen and pelvis, showing extensive pneumoperitoneum, which brought the radiologist's attention to suspect a small bowel perforation presumably accompanying a uterine perforation secondary to the D&C. There were no obvious signs of pelvic small bowel perforation in the initial CT images. The perforated duodenal stress ulcer was diagnosed the next day by a new CT scan following oral contrast ingestion and managed surgically by repair and omental patch, and no other bowel perforations were found upon surgical exploration. After the surgery, the patient was diagnosed with COVID-19, and her clinical status deteriorated gradually during the following week, and she passed away from a cardiac arrest. Conclusion: It is unclear whether septic abortion or COVID-19 has resulted in stress ulcer perforation in our patient. This case report highlights the importance of raising early suspicion in the diagnosis of stress ulcer perforation in critically ill patients to reduce the risk of morbidity and mortality.

Emergency surgical treatment of colonic acute diverticulitis: a multicenter observational study on behalf of the Italian society of colorectal surgery (SICCR) Lombardy committee.

Colonic diverticulitis can be treated conservatively, but some cases require surgery. Patients can undergo Hartmann's procedure (H) or resection with primary anastomosis (RA), with or without diverting stoma. This multicenter observational retrospective study aims to evaluate the adherence to current guidelines by assessing the rate of RA and H in Lombardy, Italy, and to analyze differences in patients' features. This study included data collected from nine surgical units performing emergency surgery in Lombardy, in 2019 and 2021. Data for each year were retrospectively collected through a survey among Italian Society of Colorectal Surgery (SICCR) Lombardy members. Additional data were about: Hinchey's classification, laparoscopic (VLS) or converted procedures, procedures with more than two operators, procedures in which the first operator was older than 40 years, night or weekend procedures, older-than-80 patients, COVID-19 positivity (just 2021). The total number of operations performed was 254, 115 RA and 130 H (45.3% and 51.2%, diff. 12%, p = 0.73), and 9 (3.5%) other procedures. RAs were more frequent for Hinchey 1 and 2 patients, whereas Hs were more frequent for Hinchey 3 and 4. RAs without ileostomy were significantly less than Hs (66 vs. 130, p = 0.04). Laparoscopy was more used for RA compared to H (57 vs. 21, p = 0.03), whereas no difference was found between RA and H with respect to conversion rate, the presence of more than two operators in the team, the presence of a first operator older than 40 years, night or weekend operations, and for older-than-80 patients. This study confirms the adherence to current guidelines for the treatment of acute colonic diverticulitis in Lombardy, Italy. It can be considered as a preliminary survey with interesting results that may open the way to a further prospective observational study to clarify some aspects in the management of this disease.

Emergency Surgery for Colon Diseases in Elderly Patients-Analysis of Complications, and Postoperative Course.

Background and Objectives: Colon diseases can turn in a clinical emergency with the onset of some important complications. Some critical conditions are more common in aged patients because they are frailer. The aim of this study is to examine patients over 80 years of age who are undergoing emergency colorectal surgery, and evaluating the aspects associated with post-operative complications and other problems in the short term. Methods: From November 2020 to February 2022, we included 32 consecutive patients older than 80 undergoing emergency surgery due to colon diseases. We collected and analysed all demographic and operative data, and then applied CR-POSSUM score and correlated this with postoperative hospital stay and the onset of postoperative complications according to the Clavien Dindo classification. Results: Postoperative factors were selectively evaluated based on the clinical scenario and different colic pathologies. There were no statistically significant differences, in terms of postoperative hospital stay, postoperative complications, reoperation rate and 30-day mortality. The number of cases of blood transfusions was significant and was more numerous in cases of intestinal perforation and bleeding cases. The value of the Operative Severity Score in bowel perforations was significantly higher. Conclusions: The use of a score to stratify the risk is a useful tool, especially in elderly patients undergoing emergency surgery. The CR-POSSUM score was important for predicting morbidity in our study. Emergency manifestations of colon diseases in the elderly show higher morbidity and mortality rates. The effect of age on outcome is a concept that needs to be emphasized, so further investigation is needed.

Two cases of intestinal perforation due to mesenteric artery embolism during extracorporeal membrane oxygenation and intra-aortic balloon pumping.

The patient in case 1 was a 50-year-old man who presented to the emergency department of the local hospital with chest pain and syncope for 3 hours due to acute myocardial infarction. He underwent cardiopulmonary resuscitation (CPR) followed by extracorporeal membrane oxygenation (ECMO), and intestinal perforation was detected on day 9. The patient in case 2 was a 58-year-old man who was admitted to the hospital with abdominal pain lasting for 3 days. He also required CPR and ECMO for cardiogenic shock, and intestinal perforation was identified on day 7 of ECMO. We believe that this case report will be important to alert clinicians to the possibility of this complication and to encourage early detection and intervention to improve prognosis. Conventionally, the gastrointestinal tract has received secondary attention in patients receiving ECMO support because the vital organs tend to be considered first. However, this case report illustrates the importance of monitoring gastrointestinal function in patients undergoing ECMO.

Sigmoid colon perforation in a SARS-CoV-2 positive neonate: a uniqueness report and a brief review.

BACKGROUND: Despite the relative prevalence of small bowel and proximal colon perforation in the neonatal period, recto-sigmoid perforation is extremely rare. Full-term neonates experience intestinal perforation less frequently than premature infants. Here we report a neonate with sigmoid perforation and simultaneous Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infection. CASE PRESENTATION: A 2550 g female neonate born at 38-weeks' gestation from a coronavirus disease-2019 (COVID-19) infected mother by cesarean section. Despite a good Apgar score in the first and fifth minutes, she was admitted to the neonatal intensive care unit with grunting and mild respiratory distress. She underwent antibiotics and oxygen by head box resulting in an Oxygen Saturation rate of 94%. The patients' respiratory distress decreased during the second day, resulting once breastfeeding without tolerance. While she passed meconium in the first 2 days, she developed abdominal distention on day 3. The nasopharyngeal SARS-CoV-2 real-time polymerase chain reaction (RT-PCR) was performed with positive results. Surgical consultation was requested and a thoraco-abdominal X-Ray was performed at this stage, which suspected to be a gastrointestinal perforation. Due to clinical deterioration and persistent abdominal distention, a contrast study was performed with water-soluble contrast, which confirmed intestinal perforation. However, the surgical exploration revealed perforation of the sigmoid colon at the posterior segment. The patient underwent antibiotic therapy, abdominal lavage, and colostomy, immediately. She was discharged in good condition approximately 14-days later. CONCLUSION: To our knowledge, this is the first report of sigmoid colon perforation in a term neonate following COVID-19.

Gastrointestinal complications (gangrene or perforation) after corona virus disease 2019 - A series of ten patients.

During the recent second wave of corona virus disease 2019 (COVID-19) pandemic in India, we managed a series of gastrointestinal complications in patients with COVID-19. We aim to highlight the key presentation and clinical course and emphasize the lessons we learnt from our series of such patients. A case review of ten consecutive patients with either bowel gangrene or perforation who were managed at our centre from March 20, 2021 to June 10, 2021. Clinical-demographic details, possible etiology, radiological findings, management and outcomes have been described. Of the 10 patients, 2 presented with bowel gangrene and 8 with perforation. In our series, all these patients were diagnosed with the help of computed tomography (CT) abdomen during the 3rd week after diagnosis of COVID-19. All had received steroid medication. Both patients with bowel gangrene and 4 of 8 patients with perforation underwent surgery, while 4 were managed non-operatively. Barring one patient, all the operated patients succumbed within 5 days of surgery after rapid clinical deterioration. Non-operative management in selected patients with perforation including placement of percutaneous drains, bowel rest and antibiotics was successful. Emergency surgery for COVID-19 related intestinal gangrene or perforation was associated with high mortality in our series. Non-operative management which avoids the added stress of a major emergency surgery particularly in patients just recovering from COVID-19 may be considered in stable patients in whom perforation appears to be contained.

A Case of Intestinal Perforation Associated with Mesenteric Thrombosis Due to Post-COVID-19 Syndrome.

PURPOSE: We aimed to present a case who developed intestinal ischemia and associated perforation and abscess due to Superior Mesenteric Vein (SMV) thrombosis caused by post-COVID-19 syndrome and discuss the preoperative Computed Tomography (CT) imaging findings used in diagnosis. CASE PRESENTATION: A 58-year-old patient presented to our clinic with a complaint of acute abdominal pain. His CT examination revealed thrombosis in SMV, congestion in the mesenteric venous structures, contamination in the mesentery, and thickening and dilatation of the jejunal loops due to ischemia. The patient had a history of acute COVID-19 infection. He had typical COVID-19 pneumonia findings (peripheral ground-glass opacities in both lung parenchyma predominantly in the lower lobe) on the thorax CT at that time. He was followed up with anticoagulant therapy. During his follow-up, a thoracic and abdominal CT was performed due to recurrent acute abdominal findings. On thorax CT, there was a web-like filling defect consistent with pulmonary embolism, traction bronchiectasis consistent with late findings of COVID-19 pneumonia, and poorly circumscribed subpleural ground glass opacities. On abdominal CT, in addition to mesenteric ischemia findings, loss of wall integrity was observed in the jejunal loops due to perforation and collection areas containing air consistent with an abscess. He was treated with small bowel resection and abscess drainage. CONCLUSION: Patients with acute COVID-19 infection should be followed up for the early diagnosis of serious symptoms that may develop due to post-COVID-19 syndrome, and contrast-enhanced CT should be the imaging method of choice to detect possible mesenteric vascular thrombosis in patients with acute abdominal symptoms.

COVID 19 and the risk of gastro-intestinal perforation: A case series and literature review.

BACKGROUND: COVID19 is a viral disease with pneumonia as its most common presentation. Many presentations and complications have been reported, but gastro-intestinal perforation has not received much attention. METHODS: three cases from our hospital are presented, and the current literature was reviewed. RESULTS, CASES: All three patients were admitted to the ICU with respiratory failure due to COVID19 pneumonia and intubated. Our first patient was treated with steroids, and subsequently diagnosed with rectal perforation on day 34 of his hospital admission. The second patient was treated with steroids and tocilizumab, and diagnosed with colonic perforation 1 day after neostigmine administration, on day 14 of his hospital admission. Our third patient was treated with steroids and tocilizumab, and diagnosed colonic perforation 4 days after neostigmine administration, on day 14 of his hospital admission. RESULTS, LITERATURE: 25 more cases were found in current literature, both upper GI and lower GI perforations, either as a presenting symptom or during the course of hospitalization. These were often associated with treatment with steroids, interleukin 6 inhibitors, or both. CONCLUSIONS: Gastro-intestinal perforation is a rare but dangerous complication of COVID19. Treatment with tocilizumab and steroids may both increase the risk of this complication, and hamper diagnosis.

Surge of Typhoid Intestinal Perforations as Possible Result of COVID-19-Associated Delays in Seeking Care, Madagascar.

During the coronavirus disease pandemic, we observed a 6.4-fold increase in typhoid intestinal perforation incidence in Antananarivo, Madagascar. Thirteen perforations occurred within 6 months (February 2020-July 2020), compared with 13 perforations during the previous 41 months (August 2016-January 2020). The increase may be attributable to delayed healthcare seeking during the pandemic.

Intestinal perforation associated with chlorine dioxide ingestion: an adult chronic consumer during COVID-19 pandemic.

COVID-19 pandemic is one of the most devastating worldwide crises in recent years. During this pandemic, people have been exposed to products that have not been proven to be safe and effective against COVID-19. We present an adult chronic consumer of chlorine dioxide, in which a fatal outcome is described. This case demonstrates that for people searching products to protect themselves from COVID-19, unregulated access to industrial disinfectants represents a dangerous alternative. To date, there is no scientific evidence to uphold the use of chlorine dioxide or chlorine derivatives as preventive or therapeutic agents against COVID-19. Researchers and general population must take into consideration the fatal possible consequences of not following communications and warnings from health authorities and government institutions.

Colonic perforation in patients with COVID-19 pneumonia - case reports.

INTRODUCTION: Gastrointestinal complications in critically ill patients during the COVID-19 pandemic pose a diagnostic and treatment dilemma. CASE REPORT: We present two cases of SARS-CoV-2 positive patients treated in our department for colon perforation. One patient was operated for a diastasic right colon perforation due to acute over distension of the bowel. The perforation in the second case was associated with chronic diverticulitis. CONCLUSION: These cases highlight the fact that besides typical respiratory symptoms and signs of COVID-19, digestive symptoms also occur. These can caused by intestinal perforation, be it directly or due to changing homeostasis of the internal environment.

Pneumatosis intestinalis and intestinal perforation in a case of multisystem inflammatory syndrome in children.

This case demonstrates pneumatosis intestinalis and small bowel perforation in a paediatric patient with multisystem inflammatory syndrome in children (MIS-C). Our patient presented with fever, abdominal pain and shortness of breath. She progressed to haemodynamic failure and small bowel perforation approximately 1 week after admission. Patients with suspected or confirmed MIS-C should be monitored closely for abdominal catastrophe, especially when critically ill in the intensive care unit.

Ischaemic bowel perforation secondary to a gravid uterus in a patient with treated inflammatory bowel disease and an ileoanal pouch: a case report.

The diagnosis of visceral perforation during pregnancy is often delayed and the management complex. A 32-year-old primigravid woman in her second trimester presented with abdominal pain and a pre-existing ileoanal pouch. Initial imaging was negative but later imaging was suggestive of serious pathology. At laparotomy, a caesarean section was performed. Peritonitis was encountered secondary to two discrete perforations in the small bowel separate from her pouch. Histology found an ischaemic perforation secondary to a pressure effect from the gravid uterus. In pregnancy, ileoanal pouches may make the interconnected bowel vulnerable to the pressure effect of the gravid uterus and perforation. Pregnant women with such a surgical history who develop symptoms suggestive of bowel perforation should have rapid imaging and their clinical team should consider early definitive surgical intervention.
