Stercoral perforation of the sigmoid colon secondary to chronic heroin use: A case report and a review of the literature.

INTRODUCTION: Stercoral perforation of the colon is a rare and life-threatening condition caused by pressure necrosis due to fecal impaction. It is commonly associated with chronic constipation, particularly in patients with neurogenic bowel disorders or prolonged opioid use. However, its occurrence in the context of chronic heroin use is rarely reported. CASE PRESENTATION: We report the case of a 40-year-old male with a 5-year history of heroin abuse who presented with diffuse abdominal pain, vomiting, and cessation of gas and stool passage for 10 days. Physical examination revealed a distended abdomen with generalized tenderness, guarding, and a rectal examination confirmed fecal impaction. Computed tomography (CT) showed massive fecal impaction in the sigmoid colon with pneumoperitoneum, indicating perforation. The patient underwent urgent exploratory laparotomy, revealing two perforations in the sigmoid colon with extensive fecal peritonitis. A segmental resection of the sigmoid colon with colostomy was performed. Postoperatively, the patient required intensive care for septic shock but eventually recovered and was referred to an addiction treatment program. DISCUSSION: This case highlights the serious gastrointestinal complications associated with chronic opioid use, particularly heroin. The pathophysiology involves opioid-induced inhibition of gastrointestinal motility, leading to chronic constipation, fecaloma formation, and subsequent perforation. Early recognition and prompt surgical intervention are crucial in managing stercoral perforation, which carries a high mortality rate if delayed. CONCLUSION: This case underscores the importance of recognizing gastrointestinal risks in chronic opioid users, especially heroin, and the need for integrated care strategies to prevent severe complications like stercoral perforation.

Spontaneous total regression of post-acute pancreatitis splenic artery pseudoaneurysm: A case report and review of the literature.

INTRODUCTION: Splenic artery pseudoaneurysms (SAP) are uncommon but significant vascular complications frequently associated with pancreatitis. These lesions carry a substantial risk of rupture and subsequent life-threatening hemorrhage. Standard treatment typically involves surgical or endovascular intervention to prevent such catastrophic outcomes. However, this case report documents a rare instance of spontaneous regression of a SAP following severe pancreatitis, challenging the established treatment protocols and highlighting the potential for conservative management under specific conditions. CASE PRESENTATION: A 65-year-old male with a past history of acute biliary pancreatitis secondary to gallstones, which was treated with laparoscopic cholecystectomy, presented with severe abdominal pain and a significant drop in hemoglobin levels. Imaging revealed acute pancreatitis with multiple pseudocysts and a newly identified 10 mm splenic artery pseudoaneurysm exhibiting recent bleeding. Although arterial embolization was recommended, the patient opted for non-invasive management. Intensive monitoring and conservative treatment were initiated. Over several days, his symptoms improved, and follow-up imaging showed spontaneous thrombosis of the SAP. One month later, a CT scan confirmed the complete resolution of the pseudoaneurysm. DISCUSSION: SAPs are serious complications of pancreatitis, often necessitating urgent intervention due to high rupture risk. This case of spontaneous regression underscores the importance of individualized management strategies. It suggests that conservative treatment may be a viable option for stable patients with resolving pancreatitis, although such cases are rare and require careful monitoring. CONCLUSION: While the primary approach to managing SAP remains interventional due to the high risk of rupture, this case highlights the potential for spontaneous regression in select circumstances. It underscores the need for personalized treatment plans.

Spontaneous rupture of a normal spleen: A case report and a review of the literature emphasizing diagnostic and surgical challenges.

INTRODUCTION: Spontaneous splenic rupture (SSR) is a rare but potentially fatal condition. It is commonly linked to underlying conditions such as infections, neoplasms, or hematologic diseases. SSR can also occur in a healthy spleen without any associated pathology, termed idiopathic splenic rupture. Symptoms range from non-specific abdominal pain to hemodynamic instability, often requiring emergency splenectomy. Early recognition using CT is crucial for improving outcomes. CASE PRESENTATION: A 32-year-old male presented with severe abdominal pain for 24 h. Examination showed stable hemodynamics but tenderness in the left upper quadrant. CT revealed a subcapsular hematoma and moderate hemoperitoneum, leading to a diagnosis of SSR. Initially managed conservatively, the patient developed hemorrhagic shock 24 h later, with hemoglobin decreasing to 6.2 g/dL. An exploratory laparotomy confirmed a superior pole splenic fracture with significant hemoperitoneum, necessitating a total splenectomy. Postoperative recovery was uneventful, and the patient was discharged on postoperative day 6 with prophylactic vaccinations and lifelong penicillin. DISCUSSION: SSR in a normal spleen is extremely rare and poses significant diagnostic and therapeutic challenges. The exact mechanisms are unclear, with theories including vascular anomalies, microtrauma, increased splenic pressure, and idiopathic factors. SSR symptoms are often non-specific, leading to misdiagnosis. Timely diagnosis using imaging, particularly contrast-enhanced CT, is essential. Management varies from conservative approaches to splenectomy, based on hemodynamic stability and splenic damage. CONCLUSION: Spontaneous rupture of a normal spleen is a critical condition requiring high clinical suspicion for timely diagnosis and management. Further research is needed to understand its pathophysiology and risk factors.

Caecal perforation secondary to intrapelvic migration of a total hip prosthesis: A case report and a review of the literature.

INTRODUCTION: Total hip arthroplasty (THA) is commonly performed to alleviate hip pain and restore function. While generally safe, complications such as prosthesis migration can occur. Intrapelvic migration of hip prostheses, leading to bowel perforation and fistula formation, is a rare but severe complication requiring prompt diagnosis and management. This case report, presented in line with the SCARE criteria, highlights a case of caecal perforation due to hip prosthesis migration. CASE PRESENTATION: A 78-year-old female with a history of right THA presented with severe hip pain, loss of function, and a persistent fistula exuding fecaloid fluid. Examination revealed fever, rigidity, and limited hip motion. CT scans showed intrapelvic protrusion of the prosthetic components and a colo-cutaneous fistula. Emergency laparotomy revealed caecal perforation by a screw from the acetabular component, necessitating resection of the perforated caecum. A subsequent surgery addressed the hip prosthesis. The patient recovered uneventfully and was discharged on day 7. DISCUSSION: Prosthesis migration into the pelvis is a serious complication of THA. Risk factors include implant loosening, acetabular bone loss, surgical technique issues, and patient factors like obesity and osteoporosis. Diagnosis relies on imaging studies. Management typically involves surgical removal of the migrated prosthesis and repair of the perforation, necessitating a multidisciplinary approach. CONCLUSION: Caecal perforation due to intrapelvic migration of a hip prosthesis is rare but potentially life-threatening. Prompt diagnosis and appropriate management are crucial. Further research is needed to better understand risk factors and prevention strategies.

A "fruitful" cause of acute appendicitis.

INTRODUCTION: Acute appendicitis is a common health problem mainly due to a lumen obstruction. The obstruction is mainly due to fecal material, lymphoid hyperplasia or parasites. Foreign bodies and especially seeds have been rarely reported as causes of acute appendicitis and account for less than 1% of the different causes. CASE REPORT: The authors described a rare case of acute appendicitis caused by seed and causing diagnostic challenge with the most frequent parasites observed in the appendix lumen. Different arguments were gathered to rule out enterobius vermicularis, taenia species, ascaris infection or schistosomiasis. CONCLUSION: Seed-caused-appendicitis has to be known and identified by pathologists in order to avoid the diagnosis of parasites infection which may induce an overuse of antibiotics after the appendectomy.

Primary Ewing sarcoma of the liver: Diagnosis, management, and prognosis: A case report and literature review.

Ewing's sarcoma tumors (ES) are a rare entity exceptionally localized on the liver. We report a case of an ES of the liver in a 26-year-old man who presented with abdominal pain. The diagnosis was confirmed with a histopathological examination of the left hepatectomy specimen and adjuvant chemotherapy was received.

Cholecystitis in a midline gallbladder: A rare ectopic location.

INTRODUCTION: The ectopic gallbladder is an uncommonly encountered anomaly that surgeons should be aware of. Its diagnosis is difficult but can be elucidated with the use of computed tomography and MRCP. PRESENTATION OF CASE: We present a case of a 64-year-old patient who presented with abdominal pain, inflammatory epigastric mass and fever. Computed tomography (CT) revealed the presence of a para-umbilical gallbladder with signs of acute cholecystitis. Laparoscopic exploration revealed that the gall bladder was not present in its usual fossa but was seen attached to the midline anterior abdominal wall with extensive adhesion between it and the omentum. Given the complexity of the cholecystectomy via the laparoscopic approach, a conversion to a midline incision was performed. The IOC confirmed the absence of anatomical variants of the biliary tree. DISCUSSION: An ectopic gallbladder is a difficult entity to diagnose as it can create clinical confusion by tampering with the common clinical presentation of cholecystitis. MRCP is currently one of the most effective preoperative examination methods as it detects the coexistence of biliary tract variation. Laparoscopic surgery is a safe procedure to be performed in the ectopic gallbladder. CONCLUSION: Ectopy of the gallbladder is a rare congenital abnormality that should be kept in mind to avoid errors or delays in management.

Hydatid cyst of the liver fistulized into the inferior vena cava.

INTRODUCTION: Fistulization or rupture of hydatid liver cysts to the inferior vena cava (IVC) is an extremely rare and life-threatening condition. PRESENTATION OF CASE: We report the case of a 70-year-old patient who presented with right-upper-quadrant pain and fullness evolving for 03 months. Physical examination showed dilated veins over the anterior abdominal wall and the flanks associated with lower-extremity swelling. Computed tomograph of the abdomen showed a hydatid cyst invading segments VI and VII of the liver fistulized into the inferior vena cava. The IVC was partially trombosed. The diagnosis of a possibly ruptured hydatid cyst in the inferior vena cava was then made. The patient underwent surgical management. Per-operatively the cystic cavity had bloody content but the cysto-vascular communication was not identified. Partial cystectomy was performed leaving a fairly extensive contact between the calcified pericyst and the IVC. The postoperative course was uneventful. DISCUSSION: Rupture of the hepatic hydatid cyst into the IVC is very rare and may lead to fatal pulmonary embolism secondary to the migration of vesicles in the pulmonary artery or haemorrhagic shock. CT scan remains the best investigation method to assess the vascular links of the hepatic hydatid cyst especially with the IVC. Surgical treatment of the hepatic hydatid cyst ruptured into the IVC mandates vascular control before the hydatid cyst is punctured or removed. CONCLUSION: Fistulized hydatid cysts into the IVC should be operated on in centres equipped for extracorporeal bypass techniques, and experienced in the surgery of hepatic echinococcosis.

Acute pancreatitis secondary to ansa pancreatica: Two new cases and review of the literature.

We described two cases of acute pancreatitis secondary to ansa pancreatica. The first patient was diagnosed on MRCP and improved after standard treatment of AP. In the second case, ansa pancreatica was diagnosed on IOP. At the second episode of AP, sphincterotomy of the minor papilla was performed.

Perforated Jejunal Diverticulitis: a rare cause of acute abdominal pain.

It is imperative for surgeons to have a heightened awareness of complications of jejunal diverticular disease so that they can act quickly and contribute to a successful clinical outcome for their patients.

Pedunculated hepatic focal nodular hyperplasia: A case report and review of the literature.

Focal nodular hyperplasia (FNH) is a common asymptomatic benign hepatic tumor encountered in middle-aged women. However, pedunculated FNH is exceedingly rare and more frequently associated with complications. That is why surgical management is mandatory in this form.

Ileocecal and hepatic tuberculosis mimicking a metastatic cecal malignancy: Case report.

We wish to highlight that on encountering a suspicious hepatic and a colonic lesion, the possibility of TB should also be kept in mind apart from the obvious possibility of metastasis of a colonic cancer especially in an endemic country like Tunisia.

Chilaiditi's sign: A rare differential diagnosis of pneumoperitoneum.

Chilaiditi sign is a rare condition typically mistaken for pneumoperitoneum. CT scan can confirm the diagnosis. Its management is conservative that is why it should be well known by surgeons to avoid unnecessary exploratory laparotomies.
