BACKGROUND: The intrauterine device is one of the effective, safe, convenient, economical, and reversible contraceptive methods. Although its contraceptive effect is definite, some female patients may experience complications such as expulsion, bleeding, and pregnancy with the device in place. Rectal perforation is one of the rare and serious complications, which can lead to complications such as abdominal infection and intestinal adhesions, severely affecting the quality of life of patients.
METHODS: A 34-year-old female was sent to the Department of Gastroenterology with noticeable left lower quadrant abdominal pain. She had presented with abdominal discomfort and anal tenesmus 1 year earlier. Two months ago, her abdominal pain had gradually worsened and she was presented to our hospital.
METHODS: Investigations, including colonoscopy and computed tomography scan, had revealed an intrauterine device migrated and perforated into the rectum.
RESULTS: The patient underwent successful colonoscopic removal of the intrauterine device. She recovered well after the treatment.
CONCLUSIONS: This case proves that endoscopic therapy can be considered the preferred method for removing intrauterine devices displaced into the digestive tract lumen.

Introduction Acute appendicitis is a common reason for acute abdominal pain. It has a high perforation rate of 20%. Diagnosis of acute appendicitis is usually through well-known clinical signs and symptoms. Radiologic imaging is by and large carried out in peculiar cases with indistinct signs and symptoms. Although various scoring methods are available for screening and diagnosis, those have inadequate validity to accurately predict the severity of acute appendicitis. From the differential counts, the neutrophil-to-lymphocyte ratio (NLR) is an economical and straightforward measure of subclinical inflammation. NLR may be a useful marker for predicting the onset and severity of appendicitis because of the insight it gives into immunological and inflammatory pathways. In this study, we aimed to determine the association between NLR and acute appendicitis among adult patients to differentiate between perforated and non-perforated appendicitis in a tertiary care hospital in Tamil Nadu, India. Methods This was a cross-sectional study conducted in the Department of General Surgery of a deemed university in Chennai, Tamil Nadu. The study was conducted from March 2022 to December 2022. Patients aged 18 years and above undergoing appendicectomy surgery were included in the study. Patients with hematology disorders, chronic kidney disease, chronic liver disease, chronic obstructive pulmonary disease, asthma, cancer, or auto-immune diseases, and any viral, bacterial, or parasitic infections were excluded. Pregnant women were also excluded from the study. After obtaining informed consent from the patients, blood samples were collected as and when they were diagnosed as acute appendicitis. Laboratory analysis for complete hemogram including white blood cell (WBC) count, neutrophil, and lymphocyte count was carried out using an automated hematology analyzer. Prevalence of perforated appendicitis was reported as a percentage. The receiver-operating characteristic (ROC) curve was developed for NLR in differentiating perforated and non-perforated appendicitis. Data were entered in Microsoft Excel 2023. These analyses were carried out in STATA 12.0 (StataCorp, College Station, Texas, USA). Results A total of 212 patients aged 18 years and above were included in the study. Among them 93 (43.9%) were male and 119 (56.1%) were female. Prevalence of perforated appendicitis observed intra-operatively was 29.7% and non-perforated appendicitis was 70.3%. The mean (SD) of NLR among patients with perforated appendicitis was 8.8 (5.1) and non-perforated appendicitis was 3.2 (2.4) with a statistically significant difference (p-value < 0.0001). ROC curve with a cut-off value of 3.78 NLR, had sensitivity of 65.9% and specificity of 93.1% in differentiating perforated and non-perforated appendicitis. The positive predictive value (PPV) and negative predictive values (NPV) were reported as 85.7% and 81.2%, respectively. Conclusion NLR has a reasonable validity in differentiating perforated and non-perforated appendicitis. NLR may be useful in low-resource settings where routine confirmatory radiological procedures like computed tomography scans are not available.

BACKGROUND: Colorectal foreign bodies are commonly encountered during surgery. They are frequently observed in men 20 to 90 years of age and have bimodal age distribution. Surgical management is necessary for cases of rectal perforation. However, surgical site infections are the most common complications after colorectal surgery.
METHODS: We discuss a case of rectal perforation in a patient who presented to our hospital 2 d after its occurrence. The perforation occurred as a result of the patient inserting a sex toy in his rectum. Severe peritonitis was attributable to delayed presentation.
CONCLUSIONS: Vacuum-assisted closure was performed to treat the wound, which healed well after therapy. No complications were noted.

To summarize the clinical features and prognosis of pediatric mature B-cell non-Hodgkin lymphoma (mB-NHL) with digestive tract perforation. The clinical manifestations, laboratory and imaging examinations, treatment and outcomes of mB-NHL children complicated with digestive tract perforation admitted to Beijing Children\'s Hospital of Capital Medical University from January 2016 to June 2023 were retrospectively analyzed. A total of 12 patients were included, with 11 males and 1 female, aged 0.8-16.0 (7.5±5.4) years. Among them, there were 10 cases of Burkitt lymphoma, 1 case of high-grade B-cell lymphoma (HGBL) and 1 case of diffuse large B-cell lymphoma (DLBCL), respectively. Intestinal involvement was involved in all cases, with St.Jude staging ranging from stage Ⅲ to Ⅳ. Eleven cases had large abdominal mass. In 7 cases, abdominal X-ray examination showed free gas under the diaphragm. Eleven cases experienced digestive tract perforation after chemotherapy, and the time of perforation after initiation of chemotherapy was 2.0-111.0 (41.2±33.6) days. The most common site of perforation was ileum (6 cases), followed by gastric wall (2 cases), jejunum (1 case), colon (1 case) and appendix (1 case). Eight patients underwent surgery, and the time between surgery and re-chemotherapy was 7.0-45.0 (17.6±12.0) days. One case with perforation before chemotherapy died after giving up treatment. The remaining 11 cases received conservative treatment or surgical intervention, followed by regular chemotherapy after symptom and infection control. The follow-up time was 6.0-82.0 (45.0±26.1) months, and all survived.

A male in his 70s with a history of artificial vessel replacement for a thoracoabdominal aneurysm had been treated non-operatively for adhesive bowel obstruction during the past two months. The initial symptom was nausea and the patient was transferred to our hospital because of diffuse abdominal pain. Computed tomography revealed pneumothorax, diaphragmatic hernia, and bowel perforation. A left thoracic drain was inserted and air and clear yellow fluid were drained. Secondary pneumothorax was presumably caused by intestinal perforation associated with diaphragmatic hernia. Although reported cases with secondary pneumothorax associated with diaphragmatic hernia and intestinal perforation are caused by trauma, this complication can occur postoperatively.

UNASSIGNED: Foreign body ingestion is frequent in younger children, with generally good outcome on conservative management. However, magnetic beads ingestion is an exceptional cause of intestinal perforation in the older children.
METHODS: An 8-year-old boy presented with clinical signs of generalized acute peritonitis. Abdominal plain X-ray confirmed the foreign object in the digestive tract and oriented the etiology by highlighting several air-fluid levels, distended small bowel loops, pneumoperitoneum and the presence of a bilobed foreign body projected adjacent to the 5th lumbar vertebra. Open surgical exploration was performed and revealed a peritoneal fluid, 2 perforations in the small bowel and 2 adhered pieces of magnets. A 20 cm ileal resection, including the segment with the 2 perforations, was performed followed by a terminal ileostomy. The restoration of gastrointestinal continuity was performed 16 days later. After a follow-up of 2 years and 8 months, the patient was free of any symptom.
UNASSIGNED: In cases of acute peritonitis due to perforation, the general condition deteriorates progressively. Fever may be absent, as was the case with our patient. Abdominal pain is the predominant symptom, it is often accompanied by vomiting that can be alimentary, bilious, or even fecaloid and/or by cessation of bowel movements and/or gas. Abdominal rigidity is a major physical sign, sometimes replaced by generalized guarding.
CONCLUSIONS: Ingestion of gastrointestinal foreign bodies is rare in older children, the presence of more than one magnet can lead to peritonitis due to intestinal perforation.

BACKGROUND: Meckel\'s diverticulum (MD) is the most common congenital abnormality of the gastrointestinal tract. However, MD is rare in clinical practice, and perforation of a MD by a foreign body is even rarer. Preoperative diagnosis is difficult because there is often insufficient information; therefore it is usually diagnosed intraoperatively. Although rare, it should be considered as a differential diagnosis in patients who have ingested foreign bodies.
METHODS: The following is the case of a 52-year-old female patient who was admitted because of generalized abdominal pain for 5 days, related to nausea and vomiting. She also stopped passing gas. Inflammatory indicators were elevated, and computed tomography (CT) revealed gas-liquid levels in the small intestine and high-density objects in the ileum. Based on the patient\'s condition, laparotomy was performed instead because the laparoscopic procedure was difficult to perform. Intraoperatively, a foreign body perforated the diverticulum of the terminal ileum, resulting in the development of an abdominal abscess. Finally, we performed resection of the ileal diverticula and partial resection of the ileum. After the surgery, it was confirmed that the foreign bodies were two dentures accidentally eaten by the patient.
CONCLUSIONS: A thorough understanding of the clinical presentation, imaging features, and treatment of MD and its complications will assist clinicians in making prompt and accurate diagnoses and providing symptomatic treatment.

This is a case report of a 70-year-old woman with possible cholestyramine-induced bowel perforation. She had a prior history of pancreaticoduodenectomy for pancreatic cancer with a daily intake of cholestyramine. She underwent emergency laparotomy for small bowel perforation twice. Subsequent pathology reports showed crystal depositions in the small bowel wall. Leasions spread out on the small bowel and the omentum during the second surgery were thought to be carcinomatosis. However, the pathology report showed no malignant cells but plenty of crystal depositions as seen with cholestyramine intake.

Background Intestinal perforation is a life-threatening condition requiring immediate surgical intervention. Surgical-site infections (SSIs) and wound dehiscence are common complications associated with emergency laparotomy for intestinal perforation. Finding optimal wound management and postoperative strategies can significantly impact patient outcomes and reduce the risk of complications. Negative-pressure wound therapy (NPWT) is a relatively recent tool employed in the care of wounds to control SSIs and foster healing. Methodology A prospective, observational, cohort study was conducted among 150 patients who underwent emergency exploratory laparotomy due to intestinal perforation at the general surgery department of a tertiary care hospital in New Delhi between July 2022 and December 2023. Preoperatively, all patients underwent initial resuscitation. Intraoperatively, the extent of peritonitis was determined and was categorized according to the Centers for Disease Control and Prevention (CDC) classification. Postoperatively, NPWT dressing was applied to the patient\'s midline laparotomy wound on postoperative day (POD) two. Negative pressure was set at 75-125 mmHg with suction. The number of NPWT dressing changes required was documented. The wound was closed with vertical mattress sutures under local anesthesia, delayed primary closure (DPC). The incidence of SSIs, the duration for DPC, the incidence of fascial dehiscence, the number of NPWT dressing changes, and the length of hospital stay were documented according to CDC groups. Results The mean age in CDC categories 2, 3, and 4 were 31.789, 28.733, and 42.676 years, respectively. The most common cause of perforation was enteric fever (n = 42, 28%), followed by tuberculosis (n = 36, 24%). Most patients had no known comorbidities (n = 80, 53.3%). Overall, 16% of patients (n = 24) were both alcoholics and smokers. The most frequent bacteria in all CDC categories was Escherichia coli. Fourteen patients developed burst abdomen in the postoperative period and were excluded from the study. The mean duration of DPC increased with higher CDC categories, with CDC category 4 displaying the most extended mean duration at 10.70 days. The number of NPWT dressing changes increases with higher CDC categories, with CDC category 4 exhibiting the highest mean at 2.00 changes. The mean hospital stay increased with higher CDC categories, with CDC category 4 showing the most extended mean stay at 17.324 days. Statistical analysis revealed no significant association between SSI occurrence and CDC categories. Conclusions NPWT followed by DPC is a promising approach to managing gastrointestinal perforations, reducing SSIs, and potentially improving patient outcomes. However, further research is needed to explore the specific benefits of NPWT in conjunction with DPC and its efficacy in various clinical scenarios.

A case describes a 49-year-old male patient who underwent emergency exploratory laparotomy for small intestinal perforation. Peritonitis was present due to perforation of the jejunal tumor. Resection of the jejunal tumor with perforation was performed followed by end-to-end anastomosis of the jejunum. The resected jejunal tumor was identified in the histopathological examination as metastatic from a clear cell variant of squamous cell/large cell carcinoma of the lung. It was associated with metastatic lesions in the brain. Metastasis from the lung carcinoma in the jejunum is a very rare condition predisposing to small intestinal perforation which is also associated with brain metastasis.
