Coincidental spontaneous perforation of the small intestine following operative hysteroscopy: A case report.

OBJECTIVE: Operative hysteroscopy is a common gynecologic procedure, but it carries the risk of complications. Spontaneous small intestine perforation is rare and fatal, especially in young adults. We present a spontaneous small intestine perforation after operative hysteroscopy with mimicking sign of uterine perforation after operation hysteroscopy. CASE REPORT: A 30-year-old nulligravida woman underwent Truclear® hysteroscopic polypectomy in the morning in LMD. She suffered from upper abdominal pain in the afternoon. Subsequently, progressive abdominal distention and imminent shock occurred the next morning. Initially, it was supposed to be a case of uterine rupture with internal bleeding. She was transferred to the emergency department of our hospital. Complete biochemistry data and abdominal CT were performed. The CT revealed pneumoperitoneum and ascites. Emergent laparoscopy was arranged. The abdominal cavity was full of intestinal fluid and the myomatous uterus was intact. The surgeon performed a laparotomy, two sites of spontaneous perforation of the small intestine were detected. The patient underwent laparotomic segmental resection and anastomosis and was discharged 14 days after surgery without incident. CONCLUSIONS: The risk of uterine perforation during hysteroscopy is up to 1.6%. The use of non-thermal intrauterine morcellator device (Truclear®) has been shown to significantly reduce the risk of perforation and thermal injury. As this case highlights, we suspected the possibility of uterine perforation immediately after hysteroscopic surgery. However, it happened to be rare spontaneous perforation of small bowel. The patient recovered well after timely transfer and management. Hysteroscopy is a very common procedure in gynecologic clinics, but even relatively safe intrauterine morcellator devices carry risk of complications. As a healthcare provider, we should beware of any comorbidity, for sometimes it would be catastrophic.

Diagnostic Accuracy of Group A Streptococcus Rapid Antigen Detection Test on Middle Ear Fluid in Children With Acute Otitis Media With Spontaneous Perforation: A Prospective Multicenter Evaluation.

Group A Streptococcus is one of the leading causes of otorrhea. The performance of rapid antigen tests in 256 children with otorrhea showed excellent sensitivity, 97.3% (95% confidence interval: 90.7%-99.7%), and specificity, 100% (95% confidence interval: 98.0%-100%). In a period of increasing invasive and noninvasive group A Streptococcus infections, an early diagnosis could be useful.

Usefulness of Thin-Slice Contrast-Enhanced Computed Tomography in Detecting Perforation Site in Congenital Biliary Dilatation: A Case Report.

The site of perforation is difficult to identify preoperatively in many cases with spontaneous perforation of congenital biliary dilatation (CBD). We report a case of spontaneous perforation of CBD in which the perforation site was identified preoperatively using thin-slice contrast-enhanced computed tomography (CT). The patient was a girl aged 1 year and 4 months. She was admitted to our hospital because of vomiting and diarrhea that had continued for 3 days prior to admission. Abdominal contrast CT on admission showed dilated common bile duct, thickening of the gall bladder wall, and marked ascites. In addition, an area of low density with a diameter of 1 cm was detected near the neck of the gallbladder. We evaluated the area via thin-slice contrast-enhanced CT and detected a defect in the wall of the bile duct. Cholangiography revealed abnormal confluence of the pancreaticobiliary duct and a protein plug in the common duct. A diagnosis of CBD with perforation of the bile duct was made, and surgery was performed. The intraoperative findings matched that seen on the enhanced CT. There are some reports of pseudocysts and fluid retention around the perforation site; however, no reports are found in which the perforation site was confirmed by preoperative CT. If localized fluid retention is observed in cases with biliary perforation, confirmation with thin-slice contrast-enhanced CT might be useful for identifying the perforation site.

[A Case of Primary Gastric Lymphoma with Spontaneous Perforation].

An 85-year-old female patient presented to the emergency department with the chief complaint of sudden upper abdominal pain. The patient suffered from anorexia and epigastric pain for a month, and a local physician suspected a diagnosis of gastric ulcer. An abdominal computed tomography(CT)scan showed intraperitoneal free air as well as irregular thickening and thinning of the gastric wall. Gastric ulcer perforation was suspected, and an emergency operation was performed. Surgical findings showed thickening of the gastric wall in the pylorus and gastric corpus but partial thinning of areas of the anterior wall of the gastric corpus with a perforation measuring 5 mm. A distal gastrectomy and reconstruction were performed using the Billroth Ⅱ method. The histopathological diagnosis was malignant gastric lymphoma(diffuse large B- cell lymphoma). Considering the patient's age and general condition, chemotherapy was not administered after surgery. The patient was alive without recurrence 8 months after the operation.

Spontaneous colonic perforation with collagenous colitis in an elderly patient.

Collagenous colitis (CC) is a variant of microscopic colitis that causes chronic, non-bloody, and watery diarrhea. The natural history of CC is generally benign and serious complications are rare. Perforation, especially spontaneous perforation, is a particularly rare complication. A 90-year-old woman presented with acute abdominal pain. She was diagnosed with peritonitis due to colonic perforation, and partial colectomy was performed. Macroscopic findings showed well-circumscribed longitudinal ulcer, and a pathological examination revealed descending colon perforation with CC. She had no history of examination and the case was considered to be spontaneous. The postoperative course was uneventful and she had no recurrence of CC after changing from the suspected drug (lansoprazole) to an H2-blocker. The characteristics of perforation by CC are characteristic longitudinal ulcer and micro-perforation. If it can be diagnosed accurately, conservative treatment may be an option. In spontaneous cases, the history of medication and the site of perforation may assist in this decision.

A crying liver: a scan pattern mimicking spontaneous perforation of the biliary ducts.

A 2-month-old infant was referred for hepatobiliary scintigraphy due to ascites of unknown cause. The top differential diagnosis was spontaneous perforation of the biliary ducts. Delayed images up to 4 hours were against this diagnosis showing normal distribution of the radiotracer throughout the bowel. However, on delayed images, the scan showed mild tracer retention in the ascites confirmed by SPECT/CT images. Surprisingly, the exploratory abdominal surgery revealed an intact hepatobiliary system, pointing toward other possible etiologies. Second-review surgery was performed due to uncontrolled progressive ascites showing congestive hepatopathy and biliary leak from the hepatic surface suggestive of the "crying liver".

A Rare Case of Extended Retroperitoneal Biloma Due to Spontaneous Perforation of Common Bile Duct, Mimicking a Strangulated Right Inguinal Hernia: A Case Report and Literature Review.

BACKGROUND Biloma is the collection of bile outside the biliary tree as a result of visceral perforation. The most common site of disruption is the gallbladder, whereas common bile duct lesions usually occur following medical procedures or trauma. Spontaneous perforation of the common bile duct has been previously reported in the literature. Retroperitoneal biloma secondary to spontaneous perforation of the common bile duct is an extremely rare pathological entity. The purpose of this report is to inform clinical doctors of this rare entity, which can have fatal consequences for the patient. CASE REPORT We present the case of an 89-year-old man who was hospitalized with symptoms of vomiting, nausea, fatigue, and diffuse abdominal pain. The clinical examination and blood tests revealed peritonitis, a finding which was confirmed by the computed tomography of the abdomen as a retroperitoneal fluid collection, extending from the region posterior to the duodenum and head of the pancreas to the right inguinal fossa. As the patient's clinical status deteriorated, an urgent laparotomy was performed, revealing the presence of retroperitoneal biloma secondary to spontaneous perforation of the common bile duct. The operation was never completed as the patient died during the operation. CONCLUSIONS The diagnosis of this entity is difficult and is made during surgery. A large spectrum of treatment approaches has been used, but, regardless of the method, the goal is to halt the spreading abdominal contamination with bile and to treat the associated biliary pathology.

Spontaneous perforation of Meckel's diverticulum: A rare entity.

Meckel's diverticulum is the most common gastrointestinal tract's congenital abnormality. Spontaneous perforation of Meckel's diverticulum is very rare and can mimic acute appendicitis. Here we report the case of an 11-year-old male patient, who was presented to the Surgical A unit of Ayub Teaching Hospital, Abbottabad on 21st January, 2021 with one-day history of abdominal pain, predominantly in the periumbilical area and right iliac fossa, associated with nausea. On physical examination his abdomen was tense, tender with guarding and generalized rigidity. A provisional diagnosis of perforated appendix or enteric perforation of a hollow viscus was made. The patient had an emergency laparotomy, where a perforated Meckel's diverticulum was discovered. Resection of the portion of gut containing Meckel's diverticulum was done along with primary anastomosis. Heterotopic gastric mucosa of diverticulitis, associated with perforation was confirmed on histopathology. The patient made an uneventful recovery during postoperative period. This case report is an interesting and an unusual case of Meckel's diverticulum complication. It highlights the importance of considering Meckel's diverticulum as a differential diagnosis in every patient presenting with acute abdomen in this age group.

Distal Vaginal Atresia with Spontaneous Perforation: A Case Report.

BACKGROUND: The definitive treatment of distal vaginal atresia is surgery, but menstrual suppression is often helpful for initial management. CASE: A 13-year-old presented with primary amenorrhea and progressive abdominal pain. She was diagnosed with distal vaginal atresia and started on hormonal suppression. She then re-presented with heavy vaginal bleeding, and follow-up imaging revealed that spontaneous perforation had occurred. There was now evidence of a tract leading from the obstructed vaginal bulge to the introitus. Vaginoplasty was complicated by the tortuosity of the tract. Under ultrasound guidance, a pull-through vaginoplasty was performed. SUMMARY AND CONCLUSION: Spontaneous perforation of an atretic vagina is rare, but in such cases, urgent vaginoplasty is indicated to prevent infection. Despite the presence of a spontaneous tract leading to the obstruction, vaginoplasty can be complex, and intraoperative ultrasound could be beneficial.

Pneumatosis intestinalis and spontaneous perforation associated with drug toxicity in oncologic patients: a case series.

Pneumatosis Intestinalis (PI) is a rare radiological finding defined as the presence of extra-luminal gas within the intestinal wall. Several anti-tumor drugs can induce a damage of the gastrointestinal walls as an adverse effect, causing loss of mucosal integrity and endoluminal gas diffusion, responsible for PI development. We retrospectively analyzed 8 cases of PI detected through radiological imaging in oncologic patients undergoing various therapeutic regimens: five patients were receiving chemotherapy, two molecular targeted therapy (MTT) and one immunotherapy. Three patients were asymptomatic and pneumatosis was incidentally detected at routinary follow-up CT and then treated conservatively. Five patients presented acute abdomen symptoms and in these cases bowel perforation was the cause of death. Our experience confirms PI and perforation as rare complications of drug toxicity, especially in oncologic patients treated with combinations of different anticancer drugs and documented the second reported case of PI associated with atezolizumab and alectinib single administration.

Spontaneous common bile duct perforation in full term pregnancy: a rare case report and review of literature.

BACKGROUND: Spontaneous biliary system perforation is a rare presentation in clinical practice especially in adults. It is rarely suspected and diagnosed preoperatively due to small number of cases, vague sign and symptoms, and ambiguous presentation. CASE PRESENTATION: We describe an interesting case of spontaneous perforation of the common bile duct in a 16 year-old female who presented a week after her first birth to the emergency department with complaints of diffuse abdominal pain, abdominal distention, fever, vomiting, and constipation. She was having generalized peritonitis but the etiology was unclear despite a thorough workup. She underwent exploratory laparotomy, and a perforation in the supra duodenal region of the common bile duct was found intraoperatively. The common bile duct was repaired over T-tube, and cholecystectomy was performed; the patient was recovered uneventfully. CONCLUSION: Spontaneous biliary perforation is a rare cause of acute abdomen in adults and extremely rare in pregnancy. Its delayed diagnoses and management can lead to a high morbidity and mortality. All physicians, especially surgeons, should be aware of this possibility and consider it a cause of peritonitis on differential diagnosis particularly when there is no apparent etiology available for presentation.

Outcomes after non-operative management of perforated diverticular disease: a population-based cohort study.

BACKGROUND: The management of perforated diverticular disease has changed in the past 10 years with a move towards less surgical intervention. This population-based cohort study aimed to define the risk of death and readmission following non-operative management of perforated diverticular disease. METHODS: Patients diagnosed with perforated diverticular disease and managed without surgery were identified from the linked Clinical Practice Research Datalink and Hospital Episode Statistics data from 2000 to 2013. The outcomes were 1-year case fatality, readmissions, and surgery at readmission. RESULTS: In total, 880 patients with perforated diverticular disease were managed without surgery, comprising 523 women (59.4 per cent). The 1-year case fatality rate was 33.2 per cent (293 of 880). The majority of deaths occurred in the first 90 days after the index admission, with a 90-day case fatality rate of 28.8 per cent. The 90-day survival rate varied by age, and was 97.2 per cent among those aged less than 65 years, compared with 85.0 per cent for those aged between 65 and 74 years, and 47.7 per cent in those at least 75 years old. Of 767 patients discharged from hospital, 250 (32.6 per cent) were readmitted (47 elective, 6.1 per cent; 203 emergency, 26.5 per cent) during a median of 1.6 (i.q.r. 0.1-3.9) years of follow-up, with similar proportions in each age category. In the first year of follow-up, only 5.1 per cent of patients required surgery, of whom 16 of 767 (2.1 per cent) required elective and 23 (3.0 per cent) emergency operation. CONCLUSION: Non-operative management of perforated diverticulitis in those aged less than 65 years is feasible and safe. Reintervention rates following conservative management were low across all age categories.

Prenatal diagnosis of left side congenital diaphragmatic hernia associated with gastric perforation.

OBJECTIVE: A congenital diaphragmatic hernia (CDH) complicated with gastric perforation is extremely rare. Herein, we report an unusual case of unexpected intrauterine gastric perforation of a left side CDH with concurrent pleural effusion and ascites. CASE REPORT: A 21-year-old female underwent prenatal ultrasound at 37 weeks of gestation and revealed a left side CDH, pleural effusion with a large thick-walled cystic mass over the left thorax, ascites, and polyhydramnios. Under the impression of CDH with suspected gastric perforation, Cesarean delivery was arranged and a male neonate was delivered. The neonate received emergency laparotomy soon and a herniation originated from the foramen of Bochdalek and a perforation located in the stomach body along the greater curvature were found. The pathologic diagnosis was consistent with a spontaneous gastric perforation with ischemic change. CONCLUSION: Sonographic findings of pleural effusion and ascites associated with CDH are clues of antenatal gastrointestinal perforation.

Open vs Minimally Invasive Approach for Emergent Colectomy in Perforated Diverticulitis.

BACKGROUND: Traditionally, perforated diverticulitis has been managed with an open approach, with a Hartmann procedure or a colectomy with primary anastomosis. Minimally invasive surgery is associated with postoperative advantages in the elective setting and may show a benefit in the emergent setting. OBJECTIVE: The aim of this study was to compare postoperative outcomes of open vs minimally invasive approaches for emergent perforated diverticulitis. DESIGN: This was a retrospective review of the American College of Surgeons National Surgical Quality Improvement Program targeted colectomy database using propensity score matching. SETTINGS: Interventions were performed in hospitals participating in the national database. PATIENTS: Patients who underwent emergent colectomy from 2012 to 2017 were included. Procedures were divided into Hartmann procedure and primary anastomosis. Open vs minimally invasive groups were defined by intention to treat. MAIN OUTCOME MEASURES: Outcomes measures included length of stay and overall morbidity and mortality. RESULTS: Of 130,616 patients, 7105 met inclusion criteria (4486 Hartmann procedure and 2619 primary anastomosis). A total of 1989 open Hartmann procedure cases were matched to 663 minimally invasive cases. The minimally invasive group underwent longer operations and had lower rates of respiratory failure. There were no differences in overall complications, mortality, length of stay, or home discharge. In the primary anastomosis group, 1027 cases were matched 1:1. The minimally invasive approach was associated with longer operative times, but reduced wound dehiscence, sepsis, bleeding, overall complications, and length of stay. No difference was detected in anastomotic leak, mortality, reoperation, or readmission rates. LIMITATIONS: Limitations include retrospective nature, data loss, nonuniformity, selection bias, and coding errors. CONCLUSIONS: Emergent minimally invasive primary anastomosis results in a shorter length of stay and decreased 30-day morbidity in comparison with open primary anastomosis for perforated diverticulitis. Emergent open and minimally invasive Hartmann procedures for perforated diverticulitis have comparable outcomes, perhaps because of a 40% conversion rate.

ABORDAJE ABIERTO VERSUS MNIMAMENTE INVASIVO PARA COLECTOMA DE EMERGENCIA EN DIVERTICULITIS PERFORADA: ANTECEDENTES:Tradicionalmente, la diverticulitis perforada se ha tratado con un abordaje abierto, con un procedimiento de Hartmann o una colectomía con anastomosis primaria. La cirugía mínimamente invasiva se asocia con ventajas posoperatorias en el escenario electivo y puede mostrar beneficio en el escenario emergente.OBJETIVO:El objetivo de este estudio fue comparar los resultados posoperatorios del abordaje abierto versus el mínimamente invasivo para la diverticulitis perforada emergente.DISEÑO:Ésta fue una revisión retrospectiva de la base de datos de colectomía dirigida del Programa Nacional de Mejoramiento de la Calidad Quirúrgica del Colegio Americano de Cirujanos utilizando el pareamiento por puntaje de propensión.ESCENARIO:Las intervenciones se realizaron en los hospitales participantes en la base de datos nacional.PACIENTES:Se incluyeron pacientes que fueron sometidos a colectomía emergente de 2012 a 2017. Los procedimientos se dividieron en procedimiento de Hartmann y anastomosis primaria. Los grupos abierto versus mínimamente invasivo se definieron por intención de tratar.PRINCIPALES MEDIDAS DE RESULTADO:Las medidas de resultado incluyeron la duración de la estancia, la morbilidad general y la mortalidad.RESULTADOS:De 130,616 pacientes, 7,105 cumplieron los criterios de inclusión (4,486 procedimiento de Hartmann y 2,619 anastomosis primaria). 1,989 casos abiertos de procedimientos de Hartmann se emparejaron con 663 casos mínimamente invasivos. El grupo mínimamente invasivo se sometió a operaciones más prolongadas y tuvo tasas más bajas de insuficiencia respiratoria. No hubo diferencias en las complicaciones generales, la mortalidad, la duración de la estancia o el alta domiciliaria. En el grupo de anastomosis primaria, 1,027 casos se emparejaron 1: 1. El abordaje mínimamente invasivo se asoció con tiempos quirúrgicos más prolongados, pero también con tasas reducidas de dehiscencia de herida, sepsis, sangrado, complicaciones generales y la duración de la estancia. No se detectaron diferencias en las tasas de fuga anastomótica, mortalidad, reintervención o reingreso.LIMITACIONES:Las limitaciones incluyen la naturaleza retrospectiva, pérdida de datos, falta de uniformidad, sesgo de selección y errores de codificación.CONCLUSIONES:La anastomosis primaria mínimamente invasiva emergente resulta en una estancia más corta y una disminución de la morbilidad a los 30 días en comparación con la anastomosis primaria abierta para la diverticulitis perforada. El procedimiento de Hartmann abierto y mínimamente invasivo de emergencia para la diverticulitis perforada tiene resultados comparables, quizás debido a una tasa de conversión del 40%.
