BACKGROUND Pancreaticoduodenectomy (Whipple procedure) is an established surgical procedure for the treatment of carcinoma of the head of the pancreas. Modifications to this procedure include gastropancreaticoduodenectomy, which includes the removal of parts of the pancreas, duodenum, and stomach. Complications of surgery include fistula formation, failure of the anastomosis, and leak of pancreatic enzymes, which can be reduced by stenting the pancreatic duct. This report is of a rare complication of pancreaticoduodenectomy and describes a case of retrograde migration of a pancreatic duct stent into the biliary tract through the orifice of the hepaticojejunostomy...

Peritoneal carcinomatosis (PC) is a common evolution of abdominal cancers. It may arise from the peritoneum itself (primary) or originate from another type of cancer especially those of gastrointestinal or gynecological origin (secondary). Without aggressive multimodal therapeutic approaches, PC is associated with a poor prognosis. Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) have been used to treat PC since 1990. In Saudi Arabia, the first CRS and HIPEC were done in 2008...

OBJECTIVES: Percutaneous bipolar radiofrequency ablation (RFA) is a minimally invasive technique for treating liver tumors. It is not always possible to insert the bipolar probes parallel to each other on either side of tumor, since it restricts maneuverability away from vital structures or ablate certain tumor shape. Therefore, we investigated how nonparallel placement of probes affected ablation. METHODS: Bipolar RFA in parallel and in divergent positions were submerged in tissue model (800 mL egg white) at 37°C and ablated...

BACKGROUND: Radiofrequency ablation (RFA) is widely used for treating liver tumors; recurrence is common owing to proximity to blood vessels possibly due to the heat sink effect. We seek to investigate this phenomenon using unipolar and bipolar RFA on an egg white tumor tissue model and an animal liver model. MATERIALS AND METHODS: Temperature profiles during ablation (with and without vessel simulation) were studied, using both bipolar and unipolar RFA probes by 4 strategically placed temperature leads to monitor temperature profile during ablation...

BACKGROUND: To evaluate our experience of radiofrequency ablation (RFA) of pulmonary metastases in patients with resected colorectal liver metastases who had concomitant or recurrent pulmonary metastases. METHODS: Clinical and treatment variables of patients undergoing RFA were collected, and their association with survival was examined. Survival analysis was performed by the Kaplan-Meier method. RESULTS: RFA was performed as concomitant sequential treatment of extrahepatic pulmonary metastases after hepatectomy in 19 patients (30%) and as salvage treatment for pulmonary recurrences after hepatectomy in 45 patients (70%)...

BACKGROUND: Surgical cytoreduction and intraperitoneal chemotherapy is increasingly accepted as an effective treatment modality for mucinous appendiceal neoplasm. For the majority of patients with low-grade histology, outcomes have been encouraging. The survival of patients with neoplasms of malignant character is protracted and this study was designed to evaluate the effectiveness of this surgical strategy on outcomes. METHODS: Forty-six consecutive patients with mucinous and nonmucinous appendiceal cancer with peritoneal dissemination were studied...
