Preoperative tranexamic acid does not reduce transfusion rates in major oncologic surgery: Results of a randomized, double-blind, and placebo-controlled trial.

BACKGROUND AND OBJECTIVES: Allogeneic blood transfusions are associated with worse postoperative outcomes in oncologic surgery. The aim of this study was to introduce a preoperative intervention to reduce transfusion rates in this population. METHODS: Adult patients undergoing major oncologic surgery in five categories with similar transfusion rates were recruited. Enrollees received a single preoperative intravenous dose of placebo or tranexamic acid (1000 mg). The primary outcome measure was perioperative transfusion rate. Secondary outcome measures included: estimated blood loss, thromboembolic events, morbidity, hospital length of stay, and readmission rate. RESULTS: Seventy-six patients were enrolled, 39 in the tranexamic acid group and 37 in the placebo group, respectively. Demographics and surgery type were equivalent between groups. The transfusion rates were 8 out of 39 (20.5%) in the tranexamic acid group and 5 out of 37 (13.5%) in the placebo group, respectively (P = .418). Median estimated blood loss was 400 mL (interquartile range [IQR] = 150-600) in the tranexamic acid group compared with 300 mL (IQR = 150-800) in the placebo group (P = .983). There was one pulmonary embolism in each arm and no deep venous thrombosis (P > .999). CONCLUSION: Preoperative administration of tranexamic acid at a 1000 mg intravenous dose does not decrease transfusion rates or estimated blood loss in patients undergoing major oncologic surgery.

Robotic Surgery for Median Arcuate Ligament Syndrome.

BACKGROUND: Compression of the celiac artery by the median arcuate ligament results in median arcuate ligament syndrome (MALS). Using a consecutive cohort of patients with MALS, this study evaluated the efficacy and safety of robotic median arcuate ligament release (MALR). METHODS: A retrospective chart review was performed on patients who underwent robotic MALR from August 2012 to April 2018. Patient workup included history and physical examination, mesenteric Doppler ultrasound, and CT (Computed Tomography) scan. Outcomes included pain improvement, length of stay, operation duration, narcotic use, and postoperative complications. RESULTS: Twenty-seven patients met inclusion criteria. Two thirds of the cohort were female and the mean age was 49 ± 15.5 years. Postprandial abdominal pain was the most common preoperative symptom (25/27, 93%). CT (Computed Tomography) was performed in 24 (89%), and celiac stenosis > 70% was observed in all. Operative duration was 95 minutes on average (range, 53-358 minutes), and in 24/27 (89%) patients, estimated blood loss was < 100 mL. Eighty-one percent of patients were discharged the day of surgery (22/27). Two cases were converted to open, with only one major complication occurring. At 30 or more days postoperation, 17 patients (68%) had full, 1 (4%) partial, and 1 (4%) no symptom resolution, 6 (24%) had symptom recurrence after initially having resolution. Fifty-six percent achieved narcotic liberation 9/16 (56%). CONCLUSIONS: Robotic MALR is a safe option for treatment of MALS with high response rates, early hospital discharge, and opportunity for narcotic liberation.

Efficacy and safety of transversus abdominis plane blocks versus thoracic epidural anesthesia in patients undergoing major abdominal oncologic resections: A prospective, randomized controlled trial.

BACKGROUND: The purpose of this study was to compare patient outcomes for thoracic epidural anesthesia (TEA) with transversus abdominis plane (TAP) blocks. METHODS: A prospective, randomized trial was performed for patients undergoing abdominal oncologic surgeries. RESULTS: There were 32 TAP and 35 TEA subjects. The TEA group demonstrated increased episodes of hypotension in the first 24 h (3 v 0.6, p = 0.02). There was no difference in 24-48 h fluid balance between the groups. Overall parenteral morphine equivalents of opioids administered for the TEA group were higher for each postoperative day (p < 0.05). The post-operative survey did not demonstrate any difference in subjective pain between the TAP and TEA groups (6 v 6 p = 0.35). There was no attributable morbidity associated with either technique. CONCLUSIONS: TAP block use was associated with lower parenteral morphine equivalent usage and decreased incidence of hypotension in the early post-operative period compared to TEA.

Is there a role for Ytrrium-90 in the treatment of unresectable and metastatic intrahepatic cholangiocarcinoma?

BACKGROUND: Selective internal radiation therapy (SIRT) with Ytrrium-90 (Y-90) has been used to treat hepatic malignancies with success. This study focuses on the efficacy and safety of Y-90 in the treatment of unresectable and metastatic intrahepatic cholangiocarcinoma (ICC). METHODS: A single-institution retrospective case review was performed for patients with unresectable and metastatic ICC treated with Y-90 between 2006 and 2016. RESULTS: Seventeen patients with ICC underwent 21 Y-90 treatments. Four patients had undergone prior liver resection, and six patients had extrahepatic disease at the time of treatment. Five year overall survival was 26.8%, with a median survival of 33.6 months. One patient underwent margin negative liver resection after a single treatment. Complications were appreciated in two cases. Ninety-day mortality was 0%. CONCLUSION: Treatment of ICC using Y-90 is a safe and promising procedure. Further research is needed to clarify its role in the treatment of unresectable and metastatic ICC.

Safety of perioperative aspirin therapy in pancreatic operations.

BACKGROUND: Antiplatelet therapy with aspirin is prevalent among patients presenting for operative treatment of pancreatic disorders. Operative practice has called for the cessation of aspirin 7-10 days before elective procedures because of the perceived increased risk of procedure-related bleeding. Our practice at Thomas Jefferson University has been to continue aspirin therapy throughout the perioperative period in patients undergoing elective pancreatic surgery. STUDY DESIGN: Records for patients undergoing pancreatoduodenectomy, distal pancreatectomy, or total pancreatectomy between October 2005 and February 2012 were queried for perioperative aspirin use in this institutional research board-approved retrospective study. Statistical analyses were performed with Stata software. RESULTS: During the study period, 1,017 patients underwent pancreatic resection, of whom 289 patients (28.4%) were maintained on aspirin through the morning of the operation. Patients in the aspirin group were older than those not taking aspirin (median 69 years vs 62 years, P < .0001). The estimated intraoperative blood loss was similar between the two groups, aspirin versus no aspirin (median 400 mL vs 400 mL, P = .661), as was the rate of blood transfusion anytime during the index admission (29% vs 26%, P = 0.37) and the postoperative duration of hospital stay (median 7 days vs 6 days, P = .103). The aspirin group had a slightly increased rate of cardiovascular complications (10.1% vs 7.0%, P = .107), likely reflecting their increased cardiovascular comorbidities that led to their physicians recommending aspirin therapy. Rates of pancreatic fistula (15.1% vs 13.5%, P = .490) and hospital readmissions were similar (16.9% vs 14.9%, P = .451). CONCLUSION: This is the first study to report that aspirin therapy is not associated with increased rates of perioperative bleeding, transfusion requirement, or major procedure related complications after elective pancreatic surgery. These data suggest that continuation of aspirin is safe and that the continuation of aspirin should be considered acceptable and preferable, particularly in patients with perceived substantial medical need for treatment with antiplatelet therapy.

Patient perspectives on postoperative visits after common general operative procedures.

BACKGROUND: Many postoperative concerns after common general operative procedures may be addressed over the phone, thereby saving time and resources for both the patient and surgeon. METHODS: Over a 6-month time period, patients who underwent laparoscopic cholecystectomy, appendectomy for uncomplicated appendicitis, and inguinal or umbilical hernia repair were mailed an anonymous survey. The primary outcome measure was whether or not patients felt their concerns could have been addressed adequately over the phone in place of an office visit. RESULTS: A total of 1,406 surveys were mailed with 339 responses (24%: 174 laparoscopic cholecystectomy, 83 inguinal hernia, 41 appendectomy, and 41 umbilical hernia). One hundred twelve (33%) felt their concerns could have been addressed adequately over the phone without an office visit. Patients who spent less time with their doctor at the appointment favored telephone follow-up (P < .001). Patients undergoing inguinal hernia were less interested in telephone follow-up compared with laparoscopic cholecystectomy (15% vs 41%; P < .001), appendectomy (15% vs 34%; P = .018), and umbilical hernia (15% vs 37%; P = .010). Of 66 patients (20%) with self-reported complications, 44% sought care from a healthcare provider other than their primary surgeon. CONCLUSION: These observations are important for healthcare organizations seeking to maximize surgeon efficiency while improving patient satisfaction.

Acinar cell cystadenoma of the pancreas: report of three cases and literature review.

INTRODUCTION: Acinar cell cystadenoma (ACC) of the pancreas was first described as a distinct pancreatic cystic neoplasm in 2002. METHODS: We have encountered three cases of ACC at our institution in addition to the 15 cases reported to date in the world literature. The gender distribution in the total cohort of patients with ACC slightly favored females (61 % female), and the median age was 49.5 years. RESULTS: Almost half (53 %) of the cases were identified incidentally, while the remainder presented with abdominal pain. The median tumor diameter was 5 cm in size, and no patients have had documented disease recurrence or progression, even in the setting of an incomplete resection. CONCLUSION: These findings suggest a relatively indolent biology, and that complete resections are curative. As we will show, surgical resection is warranted to treat symptoms and prevent local extension or malignant transformation.

Pancreaticoduodenectomy and its variants.

Pancreaticoduodenectomy (PD) is a complex surgical procedure involving resection of the duodenum, the pancreatic head and uncinate process, and the distal common bile duct. It is most commonly performed for periampullary malignancy but may also be indicated in select cases of chronic pancreatitis or benign periampullary tumors. When evaluating a patient for potential PD, the foremost question is determining the ability to perform an adequate (margin-negative) and safe resection. Herein, we present the surgical technique for performing a pylorus-preserving PD divided into the extirpative and reconstructive phases. There are a number of accepted alternatives to the pylorus-preserving PD as presented, and the commonly accepted alternatives will also be reviewed. The sequence of steps in the extirpative phase may vary depending on the tumor location (i.e., head, neck, and uncinate) and extent of disease, whereas reconstruction techniques may vary based on a given surgeon's training and preference. Multiple advancements in recent years, including those presented below, have helped to significantly reduce the operative mortality associated with PD.

Hemorrhagic hepatic cyst: report of a case and review of the literature with emphasis on clinical approach and management.

OBJECTIVE: Hemorrhage within a hepatic cyst (hemorrhagic hepatic cyst, HHC) is a complication of liver cysts that is difficult to differentiate from other neoplastic entities on imaging. Even when accurately diagnosed, there has been a lack of consensus on the optimal treatment strategy. After presenting our experience with a patient treated via laparoscopy, we aimed to conduct a review of the literature on HHCs. METHODS: A computerized search in Medline, PubMed, Google Scholar, and The Cochrane Collaboration was carried out for journal articles or abstracts published from 1950 to 2011. RESULTS: A total of 24 patients with HHCs were identified from 1983 to 2011. The cohort had an even gender distribution with a mean age of 62.7 years. Most patients presented with abdominal pain (80 %), while three (14 %) patients were asymptomatic at the time of presentation. CT imaging and ultrasound were unable to accurately diagnose HHC, whereas hyperintensity on MRI was a reliable diagnostic tool. Three (13 %) patients were managed conservatively with observation. Seven (30 %) patients had percutaneous transhepatic drainage. Among these, two patients experienced recurrence that required repeat treatment. Two (9 %) patients underwent open unroofing of their HHC and one (4 %) laparoscopically, without recurrences. Seven (30 %) patients underwent hepatic resection, whereas six (26 %) patients had a cyst enucleation for their HHCs. All patients had uneventful recoveries, with a mean follow-up of 25 months. CONCLUSIONS: MRI is a reliable diagnostic tool in the setting of an HHC. Laparoscopic unroofing of HHCs may represent a less morbid and safe treatment modality with low recurrence rates. Given the low level of clinical evidence available so far, these results should be interpreted with caution.
