Colocutaneous fistula due to an infected sigmoid adenocarcinoma: A case report of an unusual revelation.

INTRODUCTION AND IMPORTANCE: As revealed as a colocutaneous fistula with an abscess in the abdominal wall, colon cancer is rare. It should be suspected in case of a painful abdominal wall mass in elderly patients. This case presentation of an infected sigmoid adenocarcinoma aims to highlight this uncommon presentation presenting some therapeutic issues. CASE PRESENTATION: A 90-year-old woman with a past medical history of hypertension and major depressive disorder consulted the Emergency Department for lower left quadrant abdominal pain. The physical examination objectified a mild fever; lower left abdominal quadrant guarding, and abdominal mass of 10 cm with inflammatory signs. The abdominal CT scan showed a concentric thickness of the sigmoid colon with an abdominal wall abscess. She underwent an emergent laparotomy. Intraoperatively, we found an infected sigmoid tumour that invades the abdominal wall and is associated with a peritumoral abscess. This tumour was at the origin of the abdominal wall fistula. She underwent surgical drainage of the abscess, sigmoid colectomy, and colostomy. The postoperative follow-up was uneventful. The pathological examination of the operative specimen concluded with a colonic adenocarcinoma with lymph node invasion classified as pT4N2M0. CASE DISCUSSION: Despite initial medical and radiological interventions, emergent surgery became necessary to address the infected sigmoid tumour invading the abdominal wall. Pathological examination revealed advanced cancer, but timely intervention and adjuvant therapy resulted in a positive outcome with no recurrence after two years. This case emphasizes the importance of recognizing unusual colon cancer presentations and the need for swift diagnosis and intervention. CONCLUSIONS: The diagnosis of colon cancer complicated with a colocutaneous fistula remains based on pathological examination after surgical management. These tumours presented an advanced stage and correlated to a poor prognosis. This highlights the interest in screening colonoscopy in front of any digestive symptoms in elderly patients.

Neurofibromatosis Type I and Stromal Tumor with a Multiple Digestive Localization.

Neurofibromatosis type I (NF1) is also known as von Recklinghausen disease. It is a genetic disorder that affects the growth and development of nerve cell tissue, which is characterized by a multisystem disorder and an increased risk for cancer. The incidence of gastroduodenal stromal tumor during Recklinghausen disease can reach 35% in autopsies and 5% in clinical cases. In our case, the diagnosis of neurofibromatosis type I was made in a middle-aged women initially diagnosed with a pancreaticoduodenal tumor.

Colorectal barotrauma following compressed air spray to the perineum.

Colorectal injuries caused by high-pressure air compressors are rare and reported especially among industrial workers. They may appear because of intended or accidental injury. In the present paper, we report a case of colorectal injuries due to air insufflation from a distance towards the anus with the clothes on, as a means of a practical joke. The patient presented one day after the trauma to the Emergency Department with complaints of severe abdominal pain and vomiting. On examination, he had signs of peritonitis. A computed tomography (CT) scan did not show any perforation. Emergency laparotomy was performed with the suspicion of pneumatic pressure-induced lesions. A total resection of the colon was made with enterostomy. The pathologic examination of the resected piece revealed multiple gangrenous areas without perforation associated to signs of peritonitis. Follow up was uneventful. A reversal of the enterostomy was scheduled.

Small bowel and lung histiocytic sarcoma revealed by acute peritonitis: A case report with review of literature.

INTRODUCTION AND IMPORTANCE: Histiocytic sarcoma (HS) is a rare malignant neoplasm showing morphologic and immunohistochemical features of histiocytes. It is characterized typically by extranodal presentation and a poor clinical course, particularly in cases with disseminated disease. CASE PRESENTATION: This report documents a case of bifocal and aggressive HS in small bowel and lung revealed by acute peritonitis in a 63-year-old man. CLINICAL DISCUSSION: Despite its rarity, we believe that the correct diagnosis of HS is crucial for clinical treatment and prognostic prediction. CONCLUSION: The collection of additional cases of HS are important to obtain further progress in prognosis and guide treatment decisions.

Fournier's gangrene: its management remains a challenge.

Fournier's gangrene (FG) is a rapidly progressive necrotizing bacterial dermo-hypodermitis of the perineum and external genitalia. It represents a real medical and surgical emergency requiring multidisciplinary care. Our study was based on the retrospective analysis of 18 cases of FG, collected in the Department of General and Visceral Surgery of Fattouma Bourguiba University Hospital in Monastir over an 18-year period extending from January 2000 to December 2018. Our series included 18 cases of FG collected over an 18-year period, an annual incidence of one case per year. The average age of our patients was 58 years (36 to 77). The male prevalence was clear. Diabetes and old age were found to be the major risk factors. The treatment was based on an aggressive surgical debridement remains to be the cornerstone of therapy and is commonly preceded by patient preparation for the surgical act by perioperative resuscitation and broad-spectrum antibiotic therapy, possibly accompanied by hyperbaric oxygen therapy (HBOT). The vaccum assisted closure (VAC) therapy is also used, which is a non-invasive system that promotes open wound healing. Healing techniques can be once the septic risk is controlled. Dressings topical treatments, such as fatty substances or calcium alginate, in addition to skin grafts, musculo-neurotic or musculo-cutaneous cover flaps can be used. During the follow-up period, no reccurrence occurred in 14 out of the 18 cases (2 patients were lost to follow-up and 2 patients died). A colostomy was closed in 10 out of 11 cases with simple follow-ups. Restorative surgery (partial thickness skin graft) at the perineal level was performed in only one case. Despite the better understanding of its etiopathogenesis, the advent of targeted antibiotic therapy, the establishment of a better codification of surgical procedures, the contribution of hyperbaric oxygenation and reconstruction techniques, mortality rates are still high and FG remains a real health threat, thus constituting a real medical and surgical emergency.

Primary pancreatic tuberculosis mimicking pancreatic body cancer. A case report and review of the literature.

Isolated pancreatic tuberculosis (PT) is an extremely rare disease, with non-specific clinical characteristics, making the diagnosis often challenging with pancreatic cancers. Here we report a case of a 36-year-old female, who was admitted to our hospital after suffering from a 3-month history of epigastric abdominal pain, night sweats and weight loss. The physical examination was normal. The radiological findings revealed the presence of a pancreatic mass and multiple abdominal lymphadenopathy, suggestive of malignancy. The initial differential diagnosis suspected was pancreatic tuberculosis. Tuberculosis skin test was performed and was highly positive (>22 mm). Computed tomography (CT)-guided biopsy of peripancreatic lymph node was carried out and the histopathological exam confirmed the diagnosis of PT. Therefore, anti-tuberculous therapy was initiated, leading to clinical and radiological improvement. The diagnosis of PT is rare and can sometimes be misleading. It should be considered when a pancreatic mass is observed, especially in endemic countries, to ovoid unnecessary interventions.

Strangled rectal prolapse in young adults: A case report.

BACKGROUND: Rectal prolapse (RP) is an uncommon perineal disease. It is defined as a complete protrusion or intussusception of the rectum through the anus. Strangulation of the RP is rare. This complication presents requires an emergent surgery. This case presentation aims to report the therapeutic management and results of this condition. OBSERVATION: A 29-year-old men, who consulted for a sudden, painful, irreducible rectal prolapse. At the anus, there was an irreducible, edematous, without signs of ischemia or necrosis rectal prolapse measuring 25*10 cm wide. The laboratory data showed a high white blood cell count and elevated C-reactive protein. After a failure of external manual reduction under general anesthesia, the patient underwent emergent surgery. The procedure consisted of a rectosigmoidectomy with coloanal anastomosis using a perineal approach according to the Altemeier technique associated to a diverting ileostomy. The postoperative follow-up was uneventful. The patient was discharged at post-operative day five. CONCLUSION: Strangulated RP is a rare complication. Altemeier procedure remains the intervention of choice in this situation.

Pelvic abscess complicating sigmoid colon perforation by migrating intrauterine device: A case report and review of the literature.

INTRODUCTION: Intrauterine devices (IUDs) are commonly used as a contraceptive method. However, they may cause rare but potentially serious complications such as migration through the uterine wall and gastrointestinal perforation. PRESENTATION OF CASE: We report a case of a 26-year woman, carrying an IUD for 2 years, who presented to the emergency with pelvic pain with breakthrough bleeding. Abdominal imaging revealed the presence of two devices the first of which was located in the uterine cavity and the other in the wall of the sigmoid colon associated with a 5-centimeter pelvic collection. Intraoperatively, the IUD was found to be embedded in the wall of the sigmoid colon which was removed by wedge resection of the involved segment followed by a closure of the puncture with drainage. DISCUSSION: The Intrauterine Device (IUD) is an effective method of contraception, relatively well tolerated, reversible, inexpensive and widely used. However, it is not without risk. Indeed, serious complications can occur such as uterine perforation and migration to adjacent abdomino-pelvic structures. Our observation illustrates its rarity given the fact that this complication has been observed the first time in our department over the last ten years. CONCLUSION: The migration of IUD must be treated even in asymptomatic patients due to the risk of severe complications.

Gastroblastoma, a biphasic neoplasm of stomach: A case report.

INTRODUCTION: Gastroblastoma is a rare gastric biphasic tumor with both epithelial and mesenchymal components. To the best of our knowledge only eight cases have been reported in the English literature till date. PRESENTATION OF CASE: We report a case of a 29-year-old female, hospitalized for epigastric pain with poor general condition. An upper gastrointestinal endoscopy showed a polypoid mass in the stomach near the gastric cardia suspicious of gastrointestinal stromal tumor. The patient underwent atypical proximal gastrectomy with splenectomy. Detailed histopathological examination of the resected specimen revealed the diagnosis of gastroblastoma. After six months, the patient developed loco-regional recurrence for which surgical debulking was performed. DISCUSSION: Gastroblastoma is predominantly seen in young adults with non-specific complaints. They appear as submucosal lesion in the stomach mimicking gastrointestinal stromal tumor. Preoperative diagnosis is often difficult. Surgical resection remains the mainstay of treatment. On histology, they consist of mesenchymal component which stain positively for vimentin and CD10 and epithelial component which is positive for cytokeratin on immunohistochemistry. CONCLUSION: Gastroblastoma is a malignant tumor with risk of local recurrence after curative resection.

Adult's congenital bile duct cysts.

INTRODUCTION: Congenital bile duct cysts (CBDC) is a rare congenital malformation. It results from an anomaly of the biliopancreatic junction (AJBP). This condition is often diagnosed at a young age. Although, it can be asymptomatic and discovered only at an advanced age. The aim of our work was to describe the diagnosis, therapeutic and evolutionary aspects of BVCD through a series of 11 cases diagnosed in adult cases. METHODS: This is a descriptive, retrospective and monocentric study. It collects patients operated for CBDC between 01/08/1999 and 30/06/2009. RESULTS: The mean age was 45.3 years. Two men and nine women. The right hypochondria pain has been reported by all patients. On physical examination, jaundice was noted in five cases and the rest of the examination was normal. Biology showed cholestasis in six cases and cytolysis in four cases. Only one patient had hyperamylasaemia (five times normal). The preoperative diagnosis of a VBCD was reported in eight cases. Peroperative cholangiography (OCP) allowed to make the diagnosis and classify the CBDC according to the classification of Todani. Microscopic examination demonstrated three cases of associated gallbladder adenocarcinoma. The operative follow-up was simple for ten cases. A case of surgical recovery was necessary due to infection of necrotic pancreatitis. The mean follow-up was 40.6 months with extremes from one month to seven years. Only one case of death has been reported. No patient has presented a later biliary tract degeneration. Only one case of secondary biliary cirrhosis due to repeated attacks of angiocholitis has been reported. CONCLUSION: CBDC is rare. It must be suspected at any age. It is characterized by the increased risk of degeneration. Radiological examinations can suspect the diagnosis in younger and asymptomatic patients to ensure a well-conducted and timely surgical treatment.
