RESUMEN

BACKGROUND: Primary laparoscopic hiatal repair with fundoplication is associated with a high recurrence rate. We wanted to evaluate the potential risks posed by routine use of onlay-mesh during hiatal closure, when compared to primary repair. METHODS: Utilizing single-institutional database, we identified patients who underwent primary laparoscopic hiatal repair from January 2005 through December 2014. Retrospective chart review was performed to determine perioperative morbidity and mortality. Long-term results were assessed by sending out a questionnaire. Results were tabulated and patients were divided into 2 groups: fundoplication with hiatal closure + absorbable or non-absorbable mesh and fundoplication with hiatal closure alone. RESULTS: A total of 505 patients underwent primary laparoscopic fundoplication. Mesh reinforcement was used in 270 patients (53.5%). There was no significant difference in the 30-day perioperative outcomes between the 2 groups. No clinically apparent erosions were noted and no mesh required removal. Standard questionnaire was sent to 475 patients; 174 (36.6%) patients responded with a median follow-up of 4.29 years. Once again, no difference was noted between the 2 groups in terms of dysphagia, heartburn, long-term antacid use, or patient satisfaction. Of these, 15 patients (16.9%, 15/89) in the 'Mesh' cohort had symptomatic recurrence as compared to 19 patients (22.4%, 19/85) in the 'No Mesh' cohort (p = 0.362). A reoperation was necessary in 6 patients (6.7%) in the 'Mesh' cohort as compared to 3 patients (3.5%) in the 'No Mesh' cohort (p = 0.543). CONCLUSIONS: Onlay-mesh use in laparoscopic hiatal repair with fundoplication is safe and has similar short and long-term results as primary repair.

RESUMEN

INTRODUCTION: Deep vein thrombosis (DVT) continues to be a significant source of morbidity for surgical patients. Placement of a retrievable inferior vena cava (IVC) filter is used when patients have contraindications to anticoagulation or recurrent pulmonary embolism despite therapeutic anticoagulation. Although retrievable IVC filters are often used, they carry a unique set of risks. PRESENTATION OF CASE: A 67-year-old man presents to the Emergency Room (ER) following large volume melena and complaining of syncope. One year prior, the patient had been diagnosed with Glioblastoma multiforme, for which he underwent a craniotomy with near-total resection of the mass. He subsequently developed a deep vein thrombosis and underwent placement of a retrievable inferior vena cava (IVC) filter. Computerized tomography (CT) and esophagogastroduodenoscopy showed duodenal perforation by the retrievable IVC filter. The filter was successfully retrieved through an endovascular approach. DISCUSSION: Retrievable IVC filter placement is the preferred method of pulmonary embolism prevention in patients with significant risk for bleeding. Duodenal perforation by a retrievable IVC filter is a rare and serious complication. It is usually managed surgically, but can also be managed non-operatively. CONCLUSION: For patients with significant comorbidities or patients who are poor surgical candidates, non-operative management with close monitoring can serve as an initial approach to the patient with a caval enteric perforation secondary to a retrievable IVC filter.

RESUMEN

BACKGROUND: As the number of elderly people in our population increases, there will be a greater number of octogenarians who will need pancreaticoduodenectomy as the only curative option for periampullary malignancies. This study evaluated clinical outcomes of pancreaticoduodenectomy in octogenarians, in comparison to younger patients. METHODS: A retrospective review was conducted of 216 consecutive patients who underwent pancreaticoduodenectomy from January 2007 to April 2015. A two-sided Fisher's exact statistical analysis was used to compare pre-operative comorbidities, intra-operative factors, surgical pathology, and post-operative complication rates between non-octogenarians and octogenarians. RESULTS: One hundred and eighty three non-octogenarians and 33 octogenarians underwent pancreaticoduodenectomy. Of patients with periampullary adenocarcinoma, octogenarians were more likely to present with advanced disease state (P=0.01). The two cohorts had similar ASA scores (P=0.62); however, octogenarians were more likely to have coronary artery disease (P=0.03). The length of operation was shorter in octogenarians (P=0.002). Mortality rates (P=0.49) and overall postoperative complication rates (P=1.0) were similar in two cohorts; however octogenarians had a higher incidence of pulmonary embolism (P=0.02). CONCLUSIONS: Our data demonstrates that octogenarians can undergo pancreaticoduodenectomy with outcomes similar to those in younger patients. Thus, patients should not be denied a curative surgical option for periampullary malignancy based on advanced age alone.

RESUMEN

Patients with celiac artery stenosis often remain asymptomatic due to formation of extensive collateral pathways. Hepatic or anastomotic ischemia may occur when the gastroduodenal artery and these collaterals are ligated during pancreaticoduodenectomy. Here, we present a patient with severe atherosclerotic disease of the celiac axis who successfully underwent pancreaticoduodenectomy with aorto-hepatic bypass.

RESUMEN

The right hepatic artery and the common hepatic artery originate from the superior mesenteric artery in approximately 10-15% of the population. Reconstruction of the hepatic artery using the gastroduodenal artery has previously been described to repair hepatic artery injury during the performance of biliary and pancreatic resections. We report the utilization of this technique in patients undergoing pancreaticoduodenectomy for a periampullary neoplasm involving a replaced right hepatic artery.

RESUMEN

Absence of isolated infrarenal inferior vena cava (IVC) is a rare condition documented in only a few published cases and typically treated with anticoagulation. We herein describe successful surgical management of the isolated infrarenal IVC absence in a healthy 35-year-old woman who presented with disabling pelvic congestion. An ascending venogram showed the absence of infrarenal IVC with a large left ovarian vein draining pelvic collateral vessels to the normal left renal vein and suprarenal IVC. The patient was successfully treated with a common femoral vein to the suprarenal IVC bypass using a bifurcated polytetrafluoroethylene graft, with rapid symptom resolution, and remained symptom free 6 months later. This is the first reported case describing a surgical strategy for isolated infrarenal IVC absence in a symptomatic patient.

RESUMEN

BACKGROUND: There are five types of choledochal cysts, which are anomalies that involve intrahepatic or extrahepatic bile ducts, or both. These lesions are found most frequently in patients who are Asian, female, infants but are recognized with increasing frequency in adults. METHODS: We have managed 16 patients with this anomaly. One patient was Asian, and 1 was a child. There were 3 males and 13 females. The mean age was 29 years. There were 9 type I, 1 type II, 1 type III, 4 type IV, and 1 type V cysts. Resection of cysts and hepatico Roux-en-Y jejunostomy were performed in 9 patients for type I cysts. Pancreaticoduodenectomy was performed for a type I and a type IV cyst. The extrahepatic portion of a type IV cyst along with a segment of liver was resected in 1 patient. Operation was terminated on 1 patient with a type IV cyst because of extensive involvement of the intrahepatic ducts. She will undergo liver transplantation. The type II cyst was resected. No surgery was performed on a type III and type V cyst. Four of these patients were previously treated unsuccessfully by internal drainage procedures. RESULTS: There was no mortality. Morbidity was limited to a patient who previously underwent incomplete resection of a cyst and a cyst Roux-Y jejununostomy. No cholangiocarcinoma has been encountered in our patients after a mean follow-up of 5.5 years from the time of initial discovery of the choledochal cyst. CONCLUSIONS: Management of choledochal cysts is successful after their complete removal. Partial cyst resection and internal drainage is less satisfactory because of occasional pancreatitis, cholangitis, and cholangiocarcinoma. Resection of the intrahepatic and intrapancreatic portions of the cysts reduces the risk of cancer even though this risk is low after incomplete cyst excision. Biliary continuity after cyst resection is best established by Roux-Y hepaticojejunostomy.

RESUMEN

The main complications of endovascular repair of abdominal aortic aneurysms are vascular leaks and rupture, although infection and aortoduodenal fistulas have also been reported rarely. We report a case of aortoduodenal fistula with separate retroperitoneal rupture of an abdominal aortic aneurysm after endovascular stent graft repair. The initial implantation was uneventful, without any leaks at 1 month. The patient underwent open repair and did well. To our knowledge, this is the first case report of aortoduodenal fistula and associated retroperitoneal rupture of the aneurysm after endovascular stent graft repair of an abdominal aortic aneurysm.

RESUMEN

Villous adenoma of the ampulla of Vater is a rare tumor. It is a deceptive tumor because it is a premalignant lesion and biopsies of the lesion are false negative in 25% to 56% of patients. The primary focus of this report is 23 of 30 patients with villous adenoma of the ampulla of Vater who underwent Whipple operations. Paraffin blocks from 22 patients were available. In eight patients, blocks of the biopsies and the corresponding resected specimens were available. Immunohistochemical studies using antibodies to p53 and Ki-67 were performed to determine whether accumulation of these antibodies in the biopsy specimens would identify false negative biopsies. There was one operative death. The 2-, 5-, and 10-year survival rates for the 22 patients surviving a Whipple operation were 74%, 57%, and 35%, respectively. Three patients died of cancer. The mean p53 expression index was increased in adenomas to 88 (P = 0.001) and in carcinomas to 114 (P = 0.01), compared with 12.6 for normal ampullary epithelium adjacent to tumor. Significant differences in the Ki-67 proliferation index were noted between normal adjacent epithelium (13%), adenoma (34%, P = 0.0002), and carcinoma (53%, P = 0.034), as well as between adenomatous epithelium and carcinoma (34% vs. 53%, P = .012). Villous ampullary adenocarcinoma was present in 65% of patients with villous adenoma (87% if patients with carcinoma in situ in resected specimens are included). Because of the high false negative rate of ampullary biopsies, and the inability to accurately stage these lesions, we recommend pancreaticoduodenectomy in most patients. Studies with p53 and Ki-67 markers suggest that they may be helpful in the recognition of ampullary villous cancer not identified on routine biopsies.
