RESUMEN

Salmonella-induced peritonitis, secondary to spontaneous gastrointestinal perforation, is a rare but potentially life-threatening condition. We present a case of a 62-year-old female with a history of systemic hypertension, who presented with diffuse abdominal pain and altered bowel habits. Initial evaluation suggested acute gastroenteritis, but worsening symptoms led to emergent exploratory laparotomy, revealing a gastric/duodenal perforation. Peritoneal fluid analysis and culture confirmed Salmonella Paratyphi A infection. The patient underwent an emergency laparotomy with omental patch repair and received intravenous ceftriaxone, leading to a full recovery. This case underscores the importance of considering Salmonella infection in the differential diagnosis of peritonitis, prompt surgical intervention, and appropriate antimicrobial therapy for optimal management and outcomes. Further research on epidemiological trends, host-pathogen interactions, and antibiotic resistance should be explored. Clinical studies should refine diagnostic criteria and treatment protocols, while animal models can aid in understanding pathophysiology and vaccine development for Salmonella peritonitis. Public health interventions and environmental studies will enhance prevention and control strategies.

RESUMEN

Purpose: In this case we report a rare presentation of a ruptured gastroduodenal artery aneurysm (GDA) accompanied by a duodenal perforation. It contributes to the scientific literature by discussing the management approach and results in a patient with dual complications and emphasizes the importance of early diagnosis and appropriate treatment. Case presentation: A 50-year-old male presented with severe abdominal pain, anemia, and signs of hemodynamic instability. Diagnostic imaging including CTA revealed a large, thrombosed gastroduodenal artery aneurysm with evidence of rupture. The patient underwent open surgical exploration and repair to address both the aneurysm and the duodenal perforation. The patient's recovery was satisfactory and was discharged home in stable condition. Conclusion: Early diagnosis and appropriate management in gastroduodenal artery aneurysms is crucial. There is a need for individualized surgical interventions based on the patient's hemodynamic status and associated complications. Dual complications required open surgical exploration and repair, resulting in favorable outcomes.

RESUMEN

Case summary: A 5-year-old neutered Somali cat presented with a 2-week history of icterus. Diagnostic imaging revealed extrahepatic biliary obstruction (EHBO) due to a common bile duct (CBD) mass. During exploratory laparotomy, a duodenal perforation was discovered incidentally. Choledochoduodenostomy combined with the Billroth II procedure was performed after resection of the CBD mass and the proximal duodenum to treat the EHBO and duodenal perforation. Based on histological and immunohistochemical findings, the CBD mass was diagnosed as a neuroendocrine carcinoma with gastrin-producing cell differentiation. The cat recovered almost uneventfully and was discharged 11 days after surgery. The cat survived for nearly 100 days without recurrence of EHBO or duodenal perforation; however, intermittent vomiting and weight loss persisted despite supportive medications. Relevance and novel information: To the best of our knowledge, there is no detailed report on the application of choledochoduodenostomy combined with the Billroth II procedure in cats, as we used to treat the EHBO and duodenal perforation in the present case. As serum gastrin concentrations were elevated on the first day of hospitalisation, the CBD mass was diagnosed as a neuroendocrine carcinoma with gastrin-producing cell differentiation, which seemed to have caused not only EHBO but also duodenal perforation (Zollinger-Ellison syndrome). The cat survived for almost 100 days without any perioperative complications. However, this combined procedure might be considered as only a salvage option and not as a definitive treatment option in cats requiring simultaneous biliary and gastrointestinal reconstruction because postoperative supportive care could not improve the cat's condition or maintain its quality of life.

RESUMEN

The process of endoscopic retrograde cholangiopancreatography (ERCP) is inva-sive, and its related treatments have a potential risk of complications, which poses certain obstacles to its safe promotion. Therefore, it is very important to standardize the management of ERCP compli-cations and promote the widespread development of ERCP in China. The authors interpret the back-ground, significance, and key issues that need to be paid attention to in the Guidelines for the management of complications of duodenal perforation associated with ERCP in China ( 2023 edition), in order to facilitate ERCP physicians to better grasp and apply the guidelines, provide guidance and reference for the standardized management of ERCP related complications of duodenal perforation, and promote the popularization and widespread development of ERCP in China.

RESUMEN

Duodenal perforation most commonly presents with life-threatening symptoms of acute abdomen. However, in rare cases, a perforation may have an indolent course due to subclinical progression, and the patient may present with complications at the first visit. We present a case of an anterior abdominal abscess as the initial presentation of a duodenal perforation in a 65-year-old female with no pre-morbidities. The patient presented with a painful mass in the right upper quadrant associated with fever. Physical examination revealed a tender, erythematous swelling in the right hypochondrium and lumbar regions with no signs of peritonitis. Contrast-enhanced CT (CECT) of the abdomen showed a subcapsular hepatic abscess with parietal extension, but no signs of hollow viscus perforation were visible. Empirical antibiotics were given, and incision and drainage (I&D) were performed to drain around 100 mL of pus. However, drain on postop day one demonstrated bile suggesting a hollow viscus perforation, which was confirmed by a Gastrografin study.

RESUMEN

BACKGROUND: The enhanced recovery after surgery (ERAS) program established improved clinical outcomes in elective surgery; however, its role in emergencies is uncertain. This study was designed to assess the feasibility, safety, and efficacy of a tailored-ERAS (t-ERAS) protocol in patients undergoing modified Graham's patch closure for gastro-duodenal perforation. METHODS: A single-centre, prospective, parallel-arm, open-label, randomized controlled trial was conducted from February 2021 to December 2021. Patients with gastroduodenal perforation undergoing modified Graham's patch were randomly assigned to either conventional care or the t-ERAS pathway. Patients with refractory septic shock, psychiatric or neurological disorders, pregnancy, multiple perforations, sealed-off perforations, and perforation sizes greater than 1.5 cm were excluded. The primary outcome was to compare the length of hospitalization (LOH). Functional recovery parameters and morbidity were compared in secondary outcomes. RESULTS: Twenty-five patients each were included in conventional care and the t-ERAS group. In the t-ERAS group, LOH was significantly shorter (6.3 SD2.15 days versus 9.56 SD4.33 days, p = 0.001). Patients in the t-ERAS group had significantly early functional recovery (days) with time to first bowel sound (1.8 SD0.41; p 0.002), first flatus (2.52 SD0.65; p = 0.026), first stool (3.04 SD0.68; p < 0.001), first liquid diet (2.24 SD0.60; p = 0.002), and duration of ileus (2.64 SD0.86; p = 0.038). There was no significant difference in morbidity such as post-operative nausea and vomiting, SSI, or pulmonary complications between the two groups. CONCLUSION: Tailored ERAS pathways are safe and effective in reducing the LOH and promoting early functional recovery in patients undergoing emergency closure of gastro-duodenal perforation.

RESUMEN

INTRODUCTION: Isolated duodenal perforation secondary to trauma is a rare abdominal surgical condition, with a questionable surgical approach depending on the case. PRESENTATION OF CASE: This is a case report of a 27-year-old male patient who presented with a free perforation in the posterior wall of the third portion of the duodenal frame and secondary retropneumoperitoneum without injuring any contiguous organ, after a medium-impact blunt abdominal trauma during a soccer game. DISCUSSION: A laparotomy was performed, followed by duodenorraphy with Connell-Mayo suture and Lambert suture using vascular prolene in two planes. A nasogastric tube was placed up to the jejunum, and a Jackson-Pratt drain was placed in close to the duodenum next to the sutures. During hospitalization was found a positive bacterial culture of the peritoneal fluid hence received antibiotics, without complication. CONCLUSION: It is essential to make a timely diagnosis with its respective individualized surgical approach and it must be managed as an emergency surgical procedure.

RESUMEN

RESUMEN

A 71-year-old woman underwent endoscopic submucosal dissection for early duodenal cancer at the second portion of the duodenum and developed acute peritonitis due to delayed duodenal perforation. Emergency laparotomy was performed. A huge perforation formed at the descending duodenum without ampulla involvement. Pancreas-sparing partial duodenectomy (PPD) with gastrojejunostomy was performed (250 min operative time) with 50 mL of intraoperative blood loss. She required intensive care for 3 days and was discharged on postoperative day 21 with no severe complications. Emergency treatment for a major duodenal injury or perforation remains challenging because of high morbidity and mortality. An appropriate treatment should be considered according to the nature of the defect. Although PPD is an acceptable procedure for patients with a duodenal neoplasm, its use in emergency surgery is rarely reported. PPD is more reliable than primary repair or anastomosis using a jejunal wall, and less invasive than pancreaticoduodenectomy, for emergency treatment. We performed PPD in this patient because the duodenal perforation was too large to reconstruct and did not involve the ampulla. PPD can be a safe and feasible alternative surgical procedure to pancreaticoduodenectomy for a major duodenal perforation, especially in patients with a duodenal perforation that does not involve the ampulla.

RESUMEN

Nontraumatic surgical emergencies constitute a major bulk of general surgical practice. Most of the cases seen fall under routine, but now and then, a surgeon or emergency physician is faced with an unusual diagnosis or a rarer presentation of a usual diagnosis. Sharing among peers their experiences with these outliers of practice helps spread knowledge and increases the experience pool. We share our experience of a 66-year-old female who presented to our emergency with upper abdominal pain of one-day duration.

RESUMEN

Marginal ulcers are a late complication of gastric bypass surgery. A marginal ulcer is a term for ulcers that develop at the margins of a gastrojejunostomy, primarily on the jejunal side. A perforated ulcer involves the entire thickness of an organ, creating an opening on both surfaces. We will present an intriguing case of a 59-year-old Caucasian female who arrived at the emergency department with diffused chest and abdominal pain that began in her left shoulder and went down to the right lower quadrant area. The patient was in visible pain with restlessness, and her abdomen was moderately distended. The computed tomography (CT) showed possible perforation in the gastric bypass surgery area, but the results were inconclusive. The patient had laparoscopic cholecystectomy ten days prior, and the pain began right after surgery. The patient underwent an open abdominal exploratory surgery, with the closure of the perforated marginal ulcer. The fact that the patient had undergone another surgery and had pain immediately afterward also obscured the diagnosis. This case shows the rare presentation of the patientäs diverse signs and symptoms and inconclusive reports that led to the open abdominal exploratory surgery that finally confirmed the diagnosis. This case highlights the importance of a thorough past medical history, including surgical history. The past surgical history led the team to zone in on the gastric bypass area, leading to an accurate differential diagnosis.

RESUMEN

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) is crucial to the treatment of biliopancreatic diseases with iatrogenic perforation as a potential complication. As of yet, the wall load during ERCP is unknown, as it is not directly measurable during an ERCP in patients. METHODS: In a life-like, animal-free model, a sensor system consisting of five load cells was attached to the artificial intestines (sensors 1 + 2: pyloric canal-pyloric antrum, sensor 3: duodenal bulb, sensor 4: descending part of the duodenum, sensor 5: distal to the papilla). Measurements were made with five duodenoscopes (n = 4 reusable and n = 1 single use). RESULTS: Fifteen standardized duodenoscopies were performed. Peak stresses were found at the antrum during the gastrointestinal transit (sensor 1 max. 8.95 N, sensor 2 max. 2.79 N). The load reduced from the proximal to the distal duodenum and the greatest load in the duodenum was discovered at the level of the papilla in 80.0% (sensor 3 max. 2.06 N). CONCLUSIONS: For the first time, intraprocedural load measurements and exerting forces obtained during a duodenoscopy for ERCP in an artificial model were recorded. None of the tested duodenoscopes were classified as dangerous for patient safety.

RESUMEN

BACKGROUND: Repairing of a duodenal perforation is a well accepted procedure, but clinically, approximately 4% of patients develop duodenal leaks after perforation repair, increasing the risk of death. We retrospectively analyzed clinical data from 168 patients at our hospital to explore risk factors for duodenal leak after perforation repair and developed a nomogram for predicting postoperative duodenal leak. METHODS: This retrospective case-control study totalled 168 patients undergoing repair of a duodenal perforation with omentopexy at the General Surgery Department, Dongnan Hospital of Xiamen University, from January 2012 to January 2022. The patients were divided into the non-leak group and the leak group. Risk factors were evaluated by analyzing the patient's sex, shock, diameter and anatomic position of the ulcer, use of NSAIDS and Glucocorticoid, history of drinking, diabetes, chronic diseases, age, time of onset of symptoms and lab tests. RESULT: One hundred fifty-six patients (92.9%) who did not develop leaks after repair of a duodenal perforation were included in the non-leak group, and 12 (7.1%) developed leaks were included in the leak group. In univariate analysis, there were significant differences between the two groups referring to age, shock, NSAIDs, albumin, and perforation size (P < 0.05). The area under the ROC curve for perforation diameter was 0.737, the p-value was 0.006, the optimal cutoff point was 11.5, sensitivity was 58.3%, and specificity was 93.6%, the positive predictive value is 41.1%, and the negative predictive value is 98.0%. In the internal validation of the performance of the nomogram, the C-index and AUC of the model were 0.896(95%CI 0.81-0.98), demonstrating that the nomogram model was well calibrated. CONCLUSION: The study discussed the risk factors for postoperative duodenal leak in patients undergoing repair of a duodenal perforation, and a nomogram was constructed to predict the leak. Future prospective studies with large sample sizes and multiple centres are needed to further elucidate the risk of duodenal leak after repair of a duodenal perforation.

RESUMEN

A 7-year-old male mixed intact breed dog was presented with a 6-day history of lethargy and anorexia. A linear foreign body was diagnosed and an exploratory laparotomy performed. The foreign body was pushed orad and removed via gastrotomy. Two mesenteric duodenal perforations were found: one at the level of the common bile duct and a second at the duodenal flexure. Both lesions were debrided and primarily closed in a simple interrupted appositional pattern. A gastrostomy tube and closed suction drain were placed routinely. The dog recovered without complications and ate voluntarily the first day postoperatively. The drain and gastrostomy tube were removed without incident at 4 and 15 days, respectively. Five months postoperatively the dog was reported to be clinically normal. Debridement and primary closure may represent an alternative to more extensive surgery with rerouting for duodenal perforations in select cases.

RESUMEN

BACKGROUND: This study aims to summarize our experience in diagnosis and treatment of pediatric duodenal ulcer perforation in a National Center for Children's Health. METHODS: Fifty-two children with duodenal perforation hospitalized in Beijing Children's Hospital Affiliated to Capital Medical University from January 2007 to December 2021 were retrospectively collected. According to the inclusion and exclusion criteria, patients with duodenal ulcer perforation were included in the group. They were divided into the surgery group and the conservative group according to whether they received surgery. RESULTS: A total of 45 cases (35 males and 10 females) were included, with a median age of 13.0 (0.3-15.4) years. Forty cases (40/45, 88.9%) were over 6 years old, and 31 (31/45, 68.9%) were over 12 years old. Among the 45 cases, 32 cases (32/45, 71.1%) were examined for Helicobacter pylori (HP), and 25 (25/32, 78.1%) were positive. There were 13 cases in the surgery group and 32 cases in the conservative group, without a significant difference in age between the two groups (P = 0.625). All cases in the surgery group and the conservative group started with abdominal pain. The proportion of history time within 24 h in the two groups was 6/13 and 12/32 (P = 0.739), and the proportion of fever was 11/13 and 21/32 (P = 0.362). The proportion of pneumoperitoneum in the surgery group was higher than that in the conservative group (12/13 vs. 15/32, P = 0.013). The fasting days in the surgery group were shorter than those in the conservative group (7.7 ± 2.92 vs. 10.3 ± 2.78 days, P = 0.014). There was no significant difference in the total hospital stay (13.6 ± 5.60 vs14.8 ± 4.60 days, P = 0.531). The operation methods used in the surgery group were all simple sutures through laparotomy (9 cases) or laparoscopy (4 cases). All patients recovered smoothly after surgery. CONCLUSION: Duodenal ulcer perforation in children is more common in adolescents, and HP infection is the main cause. Conservative treatment is safe and feasible, but the fasting time is longer than the surgery group. A simple suture is the main management for the surgery group.

RESUMEN

Peptic ulcer disease causing perforation is extremely rare in children and primarily affects teenagers. We present a case of a perforated peptic ulcer in a 6-year-old with abdominal pain and emesis with CT findings of moderate pneumoperitoneum and pelvic free fluid without a distinct cause. He was emergently transferred, found to be peritonitic, and taken to the operating room for diagnostic laparoscopy revealing an anterior duodenal ulcer, and underwent laparoscopic Graham patch repair. Postoperatively, the child had positive fecal antigen for H. pylori. He was treated with triple therapy and underwent subsequent testing to confirm eradication. Perforated peptic ulcer is an uncommon pediatric surgical problem, and imaging may not be diagnostic as in the case presented here. Thus, clinicians need to maintain a high index of suspicion when evaluating children with free air and a surgical abdomen in the setting of long-standing abdominal pain.

RESUMEN

Duodenal perforation is a rare but severe complication during endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) and typically requires surgical intervention. With the widespread clinical use of over-the-scope clips (OTSCs), we aimed to evaluate their efficacy and safety for the closure of a duodenal perforation caused by EUS-FNA. A 79-year-old woman underwent EUS-FNA for a suspected low-density nodule in the head of the pancreas. However, duodenal perforation occurred during EUS-FNA. To minimize the patient's pain postoperatively compared with surgical intervention, we used an OTSC to close the perforation immediately and administered drug treatment for 2 weeks. The patient was discharged after complete recovery. OTSC is considered an effective and safe choice for closing a perforation at the upper corner of the duodenal bulb without surgical intervention.

RESUMEN

An isolated perforation of the duodenum is rare in cases of blunt abdominal trauma, and diagnosis is often delayed due to subtle clinical signs. We present the case of a 13-year-old male patient who presented to the hospital with an alleged history of being run over in the abdomen by a vehicle and a complaint of severe abdominal pain. Radiography of the abdomen in the standing position showed air under the diaphragm, and ultrasonography revealed free fluid in the pelvic and peritoneal cavities, clinching the diagnosis of hollow viscus perforation. The patient was resuscitated and underwent an exploratory laparotomy under general anesthesia. On exploration, no perforation was found in the intraperitoneal organs. The retroperitoneum was opened, and the Cattell-Braasch maneuver was used to approach the duodenum. A single perforation was discovered in the fourth part, and a modified graham patch repair was done. As soon as the patient's bowel sounds returned, a low-fat diet was started through a nasojejunal tube placed distal to the perforation site. The patient was discharged in good condition and is doing well with regular follow-ups. This case emphasizes the need for a high index of suspicion for gut perforation of both intra- and retroperitoneal organs after blunt trauma. This will help in early diagnosis and timely management to reduce perforation-associated mortality. Damage control surgery, with primary closure of the perforation, is well-suited and preferred in an emergency and resource-limited setting.

RESUMEN

The case of penetrating injury of the kidney caused by a foreign body mistakenly swallowing through the duodenum is rare. A 22-year-old male patient found that a strip of the foreign body penetrated the descending duodenum - the lower pole of the right kidney through an abdominal CT examination. After Multi-Disciplinary treatment, the patient underwent extracorporeal ultrasound-assisted endoscopic foreign body removal and hemostatic clamp suture. Extracorporeal ultrasound monitoring and intravenous pyelography showed that there was no leakage of contrast medium around the right kidney. No hematuria and urinary tract infection were found during the follow-up.
