Surgical management of a massive choledochal cyst.

Choledochal cysts (CC) are congenital bile duct anomalies, typically present in children. The size of CC vary, but they rarely exceed 9 cm. Surgical resection is the mainstay of treatment. This case report presents 18-year-old female with jaundice and abdominal pain. On imaging she was found to have a type I CC versus a type IVa CC. She was taken to the operating room where she was found to have a 20 cm type I CC. The patient experienced complete recovery after total resection of the extrahepatic cyst with reconstruction with a Roux-en-Y hepaticojejunostomy. Preoperative diagnosis of the type of CCs can be challenging. Proper imaging preoperatively can aid in diagnosis of these cysts, but delineation of anatomy and type may not always be possible. If treated in a timely manner, it can help prevent both long- and short-term complications.

Strangulation of intraperitoneal kidney transplant by fallopian tube.

Renal allograft strangulation is a rare complication following simultaneous kidney pancreas transplant, often causing graft loss. This case report represents the first documented case of a 35-year-old female who developed renal graft strangulation around the left fallopian tube. Our case outlines a new complication that contributes to graft loss concerning iliac fossa anatomy and variations in female patients, as well as surgical considerations that need to be made prior to transplantation. We recommend measurement of the grafted renal vessels within the iliac fossa and respective surroundings structures to allow for the ideal positioning of the grafted organ.

Incarceration of transplanted kidney through incisional hernia.

Transplanted allograft kidney herniation through an incisional hernia resulting in incarceration is a rare condition with only one other similar case reported in the literature. The primary imaging modalities used to diagnose kidney herniation are graft ultrasound, abdominal computed tomography and abdominal magnetic resonance imaging [Sugi et al. (Imaging of renal transplant complications throughout the life of the allograft: comprehensive multimodality review. Radiographics 2019;39:1327-1355)]. Treatment should be based on patient's symptoms. This case report highlights the initial presentation of hematuria in a 57-year-old male that eventually led to the diagnosis of a right-sided incarcerated grafted kidney through an incisional hernia. Subsequently, the patient underwent transplant nephrectomy.

Incidental Finding of Gallbladder Torsion During Laparoscopic Cholecystectomy.

Laparoscopic cholecystectomy is a common general surgery procedure, with over a million laparoscopic cholecystectomies performed in the United States annually. A rare presentation, which may be encountered incidentally during surgery, is torsion of the gallbladder. Gallbladder torsion is encountered in 0.01% of all patients with acute cholecystitis. It should be considered in the differential diagnosis of elderly female patients presenting with symptoms of acute or chronic cholecystitis.  In this case report, we discuss the incidental finding of gallbladder torsion during laparoscopic cholecystectomy in an 82-year-old female admitted to the hospital with symptoms of cholecystitis. Preoperative CT imaging revealed a chronic, large hiatal hernia and a dilated gallbladder containing heterogeneous densities, possibly related to sludge. During the operation, a necrotic, torsed gallbladder and long cystic duct were found. A laparoscopic cholecystectomy was performed and the remainder of the patient's hospital course was uncomplicated. Intraoperatively, our patient was found to have torsion of the gallbladder. Preoperative lab values revealed mild hyponatremia, hypokalemia, and hypochloremia with normal liver enzymes, bilirubin, and alkaline phosphatase levels. This is consistent with documented cases, as typically the biliary tree is not obstructed. Additionally, preoperative imaging rarely reveals the diagnosis. Prompt detorsion and cholecystectomy should be performed to prevent gangrene and perforation. Gallbladder torsion can result in perforation if not quickly identified and treated. We recommend prompt laparoscopic detorsion and cholecystectomy to prevent perforation.

Lymphangiography with lipiodol as a diagnostic and therapeutic approach for Chyle Leak ascites following Simultaneous Pancreas-Kidney Transplant.

Chylous ascites (CA) is the leakage of triglyceride-rich fluid into the peritoneal cavity. This most commonly occurs due to trauma of the lymphatic system. Recently, lymphangiography with lipiodol have been used with promising results in managing refractory postoperative CA. We present the case of a 35-year-old man who developed massive refractory CA post simultaneous pancreas-kidney (SPK) transplant. After conservative management with diet modifications failed, the patient underwent lymphangiography and lymph angioembolization using lipiodol. In this case report, we describe the use of lymphangiography as both a diagnostic and therapeutic approach to successfully manage large volume CA following SPK.

Small bowel obstruction due to retroperitoneal hernia following renal transplant: a case report.

Para duodenal hernias, the most common type of retroperitoneal hernias, are thought to occur naturally from abnormal gut rotation because of fusion folds within the peritoneum. Retroperitoneal hernias are a rare postoperative complication and have not been described after renal transplantation via a retroperitoneal approach. This case report presents a 48-year-old male with intestinal obstruction after renal transplant due to herniation into the retroperitoneum via an incidentally created peritoneal defect. We suggest computed tomography with oral contrast be used in the early postoperative phase to assess for obstruction in patients with prolonged ileus of unclear etiology who have undergone retroperitoneal dissection. Small peritoneal defects should be closed during dissection. Larger, or multiple peritoneal defects should be extended to make a single, large defect to decrease the possibility of bowel herniating and becoming incarcerated.

Nonoperative management of gastrointestinal bleeding after a simultaneous pancreas and kidney transplant.

With a shift toward enteric drainage techniques, the complications associated with simultaneous pancreas and kidney (SPK) transplant have also changed. Gastrointestinal (GI) bleeding is one of the most common complications associated with SPK. This case report describes the treatment of a postoperative GI hemorrhage using the push endoscopy technique. A 48-year-old male underwent an uneventful SPK transplant with entero-systemic drainage and developed hematochezia. The push enteroscopy technique was utilized to treat the bleeding ulcer. Historically, the use of the push enteroscopy technique to treat GI bleeding from the small bowel is not described in the literature. One of the limitations of duodenojejunostomy is that standard endoscopy cannot be readily used to visualize the duodenojejunostomy. However, the use of push enteroscopy may prove to be a minimal invasive and cost-effective intervention for GI bleeding after SPK.

Surgical approach for kidney transplantation under spinal anesthesia.

Kidney transplantation is the treatment of choice for patients with end-stage renal disease (ESRD). It has been shown to improve quality of life as well as extending life of patients with ESRD as compared to renal replacement therapy (5-year survival rate of 68% after transplant vs 36% dialysis) (Hart A, Smith JM, Skeans MA. OPTN/SRTR 2015 annual data report: kidney. Am J Transplant 2017;17:21-116). Traditionally, patients undergo general endotracheal tube anesthesia for this surgery. During the COVID-19 pandemic, general anesthesia drugs and airway equipment were in short supply. Additionally, airway manipulation was avoided when possible due to concern for virus spread from aerosolizing procedures (i.e. intubation/extubation). In this case report, we review a 65-year-old female with an ESRD due to hypertension and diabetes that underwent deceased donor kidney transplant under spinal anesthesia. We will further discuss the benefits of spinal anesthesia in renal transplant operations.

The presence of donor liver granuloma requiring further workup to rule out parasitic disease.

A shortage of donor organs is a major limitation to liver transplantation. Expansion of donor pool criteria to include patients with schistosomiasis diagnosed on liver biopsy might allow the allocation of more transplant livers. Schistosomiasis is a chronic parasitic disease affecting millions in endemic areas including sub-Sahara Africa that might lead to the development of granulomas as a response to the parasite's ova and might cause chronic liver disease and portal hypertension. Due to increased mobility globally, schistosomiasis may be encountered in non-endemic areas. Currently, the usage of donor livers with known Schistosomiasis is not universally defined.
