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.

Although organ transplantation is associated with significant survival rates and cost benefits, postoperative complications still occur. Gastrointestinal complications, including those involving the stomach and intestines, account for 1-6% of posttransplant complications, with intestinal perforation specifically accounting for approximately 9%, depending on the center. In Vietnam, there are no comprehensive reports on these complications. Therefore, we report three clinical cases of gastrointestinal perforation following transplantation. Three cases of intestinal perforation are described in this case series. In 2023, a 16-year-old female patient who underwent heart transplantation for congenital heart disease was diagnosed with intestinal perforation on the 12th day. The patient required continued blood filtration support after surgery. In 2018, six days after liver transplantation, a 56-year-old male patient was diagnosed with intestinal perforation, which was subsequently repaired, and the ends of his intestines were removed. The patient was discharged in stable condition after 30 days. In 2017, five days after kidney transplantation, a 46-year-old female patient was diagnosed with intestinal perforation, which was repaired, and the perforation site was left open. The patient was discharged in stable condition after 40 days. Intestinal perforation is a relatively rare, but not uncommon, complication. Early diagnosis is challenging due to nonspecific clinical symptoms and signs. Considering the possibility of intestinal perforation and obtaining early abdominal computed tomography imaging can help prevent delayed diagnosis.

This case report outlines the intricate management of rectal perforation following laser hemorrhoidoplasty in a 31-year-old female, leading to an acute abdomen, sepsis, and multiorgan failure. Urgent laparoscopic exploration and the establishment of a double-loop colostomy were undertaken, marking the beginning of a complex course characterized by relapsed pelvic sepsis. Laser hemorrhoidoplasty has gained widespread acceptance for its minimally invasive approach in treating hemorrhoids. Remarkably, to our knowledge, the case we present is the first major complication reported after laser hemorrhoidoplasty, likely attributed to collateral thermic and mechanical tissue damage.

BACKGROUND: Our aim was to describe the clinical outcomes of surgical interventions performed for the management of colonoscopy-related perforations and to compare these outcomes with those of matched colorectal surgeries performed in elective and emergency settings.
METHODS: We included patients with endoscopic colonic perforation who underwent surgical intervention from the 2014-2017 National Surgery Quality Improvement Program participant use data colorectal targeted procedure file. The primary outcome in this study was short term surgical morbidity and mortality. Patients (group 1) were matched with 1:2 ratio to control patients undergoing same surgical interventions for other indications on an elective (group 2) or emergency basis (group 3). Bivariate analysis was conducted to compare categorical variables between the three groups, and multivariate logistic regression was used to evaluate the association between the surgical indication and 30-day postoperative outcomes.
RESULTS: A total of 590 patients were included. The average age of the patients was 66.5±13.6 with female gender predominance (381, 64.6%) The majority of patients underwent open colectomy (365, 61.9%) while the rest had suturing (140, 23.7%) and laparoscopic colectomy (85, 14.4%). Overall mortality occurred in 4.1% and no statistically significant difference in mortality was found between the three techniques (P=0.468). Composite morbidity occurred in 163 patients (27.6%). It was significantly lower in laparoscopic colectomy (14.1%) compared to 30.2% and 29.4% in open colectomy and suturing approaches (P=0.014). Patients undergoing colectomy for iatrogenic colonic perforation had less mortality, infection rates and sepsis, as well as bleeding episodes compared to those who had colectomy on an emergent basis. Outcomes were comparable between the former group and patients undergoing elective colectomy for other indications.
CONCLUSIONS: Surgical management of colonoscopy related perforations is safe and effective with outcomes that are similar to that of patients undergoing elective colectomy.

BACKGROUND: Ileal perforation caused by the insertion of a drainage tube is a rare complication. Hence, the utilization of surgical drains in abdominal surgery remains controversial. At present, there is a trend to reduce the utilization of drains in abdominal surgery, although certain situations may necessitate their application.
METHODS: A 25-year-old Chinese woman presented with a history of right lower abdominal pain persisting for 10 days. Imaging examinations, including abdominal computed tomography and ultrasound, identified low-density lesions measuring 10 × 8 × 8cm3 in the right lower abdomen, which are consistent with perforated appendicitis complicated by a peri-appendiceal abscess. A laparoscopic appendectomy was carried out. On the 5th postoperative day, the drainage fluid changed to a grass-green color (80mL). Imaging with retrograde contrast through the drainage tube revealed that the 26 Fr silicon rubber drainage tube tip was positioned 50cm away from the ileocecal junction within the ileum. Both the ileal and ileocecal regions appeared well-developed.
RESULTS: Oral intake was suspended, and the patient received antacids, somatostatin, antibiotics, and total parenteral nutrition. On the 19th postoperative day, a follow-up imaging procedure using retrograde contrast through the drainage tube indicated that the tube tip was sealed. The treatment concluded on day 33 postoperatively, and the patient was discharged.
CONCLUSIONS: Ileal perforation due to an abdominal drainage tube following laparoscopic appendectomy constitutes a rare but serious complication. However, due to the adhesion and inflammatory changes around the abscess, laparoscopic dissection becomes a challenging and risky process, and the surgical skills and experiences are particularly important. Removing the abdominal drainage tube promptly based on the characteristics of the drainage fluid is recommended. The findings provide valuable insights for surgeons navigating similar challenges.
