Management of a Large Abdominal Desmoid Tumor Complicated by Lymphedema of the Lower Limb: A Case Report.

Desmoid tumors, while generally benign histologically, can exhibit locally aggressive behavior, especially when located in the anterior abdominal wall. This case report explores the management of a rare giant desmoid tumor complicated by concurrent lymphedema, emphasizing the nuances of diagnosis, treatment decisions, and their impact on the patient's quality of life. The patient, a 55-year-old obese individual with a BMI of 47, presented with a 25 cm mass in the right paraumbilical region, alongside significant lymphedema in the right lower limb and associated inguinal lymphadenopathy. Abdominal CT revealed a well-defined soft tissue mass in the right paramedian hypogastric region, suggestive of a desmoid tumor. Surgical intervention involved a monobloc resection of the mass with a 5 cm lateral margin, including the right rectus abdominis muscle and associated aponeuroses, and subsequent reconstruction using a biface intraperitoneal synthetic mesh. Postoperative recovery was marked by the resolution of lymphedema and a return to full function of the affected limb. Histopathological examination confirmed the diagnosis of a desmoid tumor. This case underscores the importance of radical surgical resection with adequate margins and appropriate reconstruction to achieve favorable long-term outcomes. The report provides insights for future research and therapeutic advancements in the management of desmoid tumors.

Surgical Treatment of Pseudoaneurysm of the Right Hepatic Artery Following Cholecystectomy: A Case Report.

Pseudoaneurysms of the right hepatic artery following cholecystectomy are caused by either vascular damage or erosion after a biliary leak. Symptoms often include haemobilia, melena, vomiting, jaundice, and hemodynamic failure due to aneurysm rupture. The ideal treatment is arterial embolization or, in rare cases, stenting. We present a case of pseudoaneurysm of the right hepatic artery post-laparoscopic cholecystectomy. The patient presented with abdominal pain, vomiting, and hemodynamic failure on postoperative day 45. Magnetic resonance imaging (MRI) showed a large hematoma and a pseudoaneurysm of the right hepatic artery. A laparotomy was performed, and a large hematoma was found and evacuated. After the pringle maneuver, the pseudoaneurysm was resected. The right hepatic artery was ligated with clips, and a sub-hepatic drain was placed. The non-availability of emergency embolization forced surgical closure of the right hepatic artery, which is still the first-line treatment for such cases. Injury of the right hepatic artery is a rare complication, often overlooked by surgeons, and requires early diagnosis. Surgical treatment is reserved for cases of embolization failure or hemodynamic instability.

Circular Mini-Incision in the Left Iliac Fossa Followed by Purse-String Closure as a Minimally Invasive Approach for the Sigmoid Volvulus: A Technical Note.

INTRODUCTION: Volvulus of the sigmoid is a common cause of intestinal obstruction in Morocco. It is a serious condition with substantial mortality. Initial endoscopic decompression followed by resection of the redundant colon via laparotomy or laparoscopy is the procedure of choice. Exteriorization of the sigmoid colon through a linear skin incision in the left iliac fossa has been described as an alternative approach for the classic midline incision, with or without laparoscopic assistance, with acceptable results. METHODS: We describe herein a novel, minimally invasive approach for fit patients with non-complicated volvulus sigmoid. This approach consists of a skin-disk incision in the left iliac fossa, exteriorization of the redundant colon, and resection with or without primary anastomosis, followed by a purse-string closure. RESULTS: A 65-year-old patient with no prior notable medical history, presented to the emergency department with his first episode of sigmoid volvulus. A skin-disk incision was made in the left iliac fossa, exteriorization of the sigmoid was done easily through the incision, and resection and manual anastomosis were done. The closure was made in a purse-string fashion. Recovery was uneventful and the patient was discharged home on the fourth postoperative day. No wound infection was noted and the cosmetic result was satisfactory. CONCLUSION: Left iliac skin-disk incision followed by a purse-string closure is an option for approaching the abdomen in the case of sigmoid volvulus. It has been demonstrated that this technique helps reduce wound-related complications in patients undergoing stoma reversal. Authors suggest that cosmetic results are better and the incidence of surgical site infection can be lower with this technique as compared to the classic linear skin incision. Results, however, should be confirmed by larger studies.
