Mesenteric cystic lymphangioma misdiagnosed as ovarian cyst in a 63-year-old female: A case report and review of literature.

INTRODUCTION: Cystic lymphangioma is rare benign tumor that results from a lymphatic system malformation. The mesenteric location is even more uncommon. CASE REPORT: We report the case of a menopausal 63-year-old woman who presented with a persistent painful well-defined mass of the pelvis. On ultrasound and computed tomography, the mass appeared as thick-walled unilocular homogenous cyst in favor of an ovarian cystadenoma. During laparotomy, the misdiagnosis was confirmed as the tumor was found to be embedded in the mesentery of the ileum. Subsequent histopathological examination confirmed the benign cystic lymphangioma diagnosis. DISCUSSION: Mesenteric cystic lymphangioma is rare peritoneal tumor of the adult. Clinically, it often masquerades as other abdominopelvic masses like ovarian cysts. Differential diagnosis is often challenging because of the overlapping clinical abdominal presentation and radiological features. Histopathological is the gold standard in diagnosing mesenteric cystic lymphangioma. Surgery is the mainstay treatment, and the recurrence rate is low if negative surgical margins are achieved. CONCLUSION: Mesenteric cystic lymphangioma often mimics more frequent and potentially malignant lesions. It is essential for surgeons to remain vigilant for the possibility of this diagnosis when evaluating abdominopelvic cystic masses.

Synchronous anal mucinous adenocarcinoma and anal tuberculosis presenting as chronic anal fistula: Challenging management.

Metachronous anal tuberculosis to an anal adenocarcinoma is an exceptional condition. The aim of our study was to report management of the first case of synchronized anal canal adenocarcinoma and anal canal tuberculosis and report our multidisciplinary approach. A 71-year-old man was admitted for non-healing anal fistula. Rectal examination at supine position showed an ulcerative growth at the medio-superior quadrant on a radius of 2cm from the anal verge. Digital rectal examination assessed no tumor in the anorectum. Biopsy of fistulae confirmed diagnosis of anal mucinous adenocarcinoma with coexisting anal tuberculosis. Further exploration confirmed diagnosis with no distal metastasis, no active pulmonary tuberculosis and no immunodepression. Adjuvant anti-bacillary chemotherapy was initiated 1 month prior to adjuvant radio-chemotherapy. Patient was re-admitted at the 6th week following the last dose of radio-chemotherapy for surgery. On long-term evaluation at 10 months, the patient reported absence of symptoms with weight gain. Association of both entities is rare. Chronic inflammatory damage may possibly initiate a sequence of metaplasia and dysplasia, resulting in neoplastic transformation. Anal canal adenocarcinoma treatment follows same guidelines as rectal cancer. Extra-pulmonary tuberculosis treatment follows anti-bacillary protocol with consequent side effects. Therefore, our case is a unique clinical challenge for physicians. Management decision was multidisciplinary process. Their pathophysiology relationship is yet to be understood. Moreover, each entity has defined and individual therapeutic protocols and indications. All this taken into consideration, such case presents a clinical and therapeutic challenge for physicians.

Open approach for ileocolic resection in Crohn's disease in the era of minimally invasive surgery: indications and perioperative outcomes in a referral center.

Minimally invasive surgery (MIS) is the first-line approach for ileocolic resection in Crohn's disease (CD), and it is safe and feasible, even with severe penetrating CD or redo surgery. While MIS indications are continually broadening, challenging CD cases might still require an open approach. This study aimed to report rate and indications for an upfront open approach in ileocolic resection for CD. Comprehensive perioperative data for all consecutive patients undergoing ileocolic resection for CD between 2014 and 2021 in a high-volume referral center for CD and MIS, were collected retrospectively. Indications for an upfront open approach were reviewed separately by two authors according to the preoperative visit. Among 319 ileocolic resections for CD, 45 (14%) were open and 274 (86%) MIS. Two or more of the below indications were present in 40 patients (89%) in the open group, while only in 6 patients (2%) in the MIS group (p < 0.0001). Indications for upfront open approach were severe penetrating disease (58%), adhesions at previous surgery (47%), history of abdominal sepsis (33%), multifocal and extensive disease (24%), abdominal wall involvement (22%), concomitant open procedures (9%), small bowel dilatation (9%), and anesthesiologic contraindications (4%). MIS was never performed in a patient with abdominal wall involvement, concomitant open procedure, and anesthesiologic contraindication to MIS. This study can help guide patients, physicians, and surgeons. An abdominal wall involvement or the presence of two of the above indications predicts a high surgical complexity and may be considered as a no-go for the MIS approach. These criteria should prompt surgeons to strongly consider an upfront open approach to optimize the perioperative planning and care of these complex patients.

Synchronous sigmoid cancer and abdominal aortic aneurysm treated by laparoscopic colectomy followed by endovascular aneurysm repair.

INTRODUCTION: The occurrence of synchronous abdominal aorta aneurysms and colorectal cancer represents a real management challenge. Up till now, there is no evidence-based consensus recommendation in the surgical management of such patients. Herein we reported the clinical management challenge of synchronous abdominal aorta aneurysms (AAA) and colorectal cancer (CRC). PRESENTATION OF CASE: 78-year-old man was admitted in our structure for acute abdominal pain, vomiting and constipation. His past medical history included type 2 diabetes, arterial hypertension and a stable infra-renal aortic aneurysm documented 2 years ago. Physical examination found a stable patient with blood pressure and heart rate within normal range, pulsatile mass along with abdominal distension with vital signs within normal limits. Abdominal CT scan and subsequent CT angiogram confirmed an 88 × 75 mm infra-renal aortic aneurysm concomitant with considerable lumen reduction due to asymmetric wall thickening of the sigmoid. Colonoscopy combined with biopsy examination confirmed structuring irregular sigmoid adenocarcinoma Therefore we report a case of a large AAA and concomitant sigmoid adenocarcinoma tumor causing stricture. DISCUSSION: In such situation, the main controversy is the necessity of treating the diseases simultaneouslor in two stages favoring the AAA management first. To our best knowledge, we report the first case published in literature in which the patient was treated for colorectal cancer first by laparoscopic surgery followed by AAA management with EVAR. CONCLUSION: In this case report, we highlight some tricks required in performing laparoscopic sigmoid colectomy for patient with large AAA to prevent per-operative pitfalls. Evidence-based consensus is required to determine the optimal surgical treatment.
