Follicular Cholangitis: A Rare Cause of Benign Biliary Stricture.

Introduction: The differential diagnosis of focal biliary strictures comprises both malignant and benign conditions. We report a rare case of follicular cholangitis presenting with segmental stricture of the left hepatic duct. Case description: An asymptomatic 59-year-old male with no past medical history presented with dilation of the left intrahepatic bile ducts revealed as an incidental finding on an abdominal ultrasound. Blood examinations showed only a slightly elevated γ-glutamyl transferase (γGT) value, while carbohydrate antigen 19-9 (Ca 19-9) and serum immunoglobulin G4 (IgG4) were within normal range. Abdominal computed tomography and magnetic resonance imaging/magnetic resonance cholangiopancreatography (MRI/MRCP) scans revealed a high grade focal intrahepatic stricture of the left hepatic duct (FIHS type III) with proximal dilatation. Given that a diagnosis of cholangiocarcinoma could not be ruled out, the patient was referred for a left hepatectomy with regional lymph node dissection. Histological analysis showed a lymphoplasmacytic infiltration of the left hepatic duct with fibrosis and follicle formations in the submucosa, findings consistent with follicular cholangitis. The postoperative course was uneventful and there is no evidence of recurrence 8 months after the surgery. Discussion: The clinical and imaging presentation of follicular cholangitis is very similar to cholangiocarcinoma, rendering it a challenging diagnosis preoperatively. Conclusion: The approach to these cases should be primarily surgical. Even though it is very rare -- our report is the 13th case reported worldwide -- follicular cholangitis should be included in the differential diagnosis of focal biliary strictures. LEARNING POINTS: The differential diagnosis of biliary strictures comprises malignancies, like cholangiocarcinoma, as well as benign conditions.It is very challenging to distinguish between malignant and benign biliary strictures preoperatively, so the most reliable treatment approach to these cases is often surgical.Follicular cholangitis is a very rare condition and more data is needed to better understand disease pathophysiology, management, recurrence rates, and possible alternatives to surgery.

Expectations of Hepato-Pancreato-Biliary Fellows; Do We Meet Them?

OBJECTIVE: There are 16 accredited hepatopancreatobiliary (HPB) fellowships in North America. The purpose of this study is to portray the expectations of the incoming HPB fellows about their training and its implication on their career. DESIGN: A 29-questions survey was sent out to all HPB fellows starting in August 2017. The survey was divided in 3 sections depicting background, in-training and postfellowship expectations. Descriptive statistics were generated for aggregate survey responses. SETTING: This study was performed through an online questionnaire that was sent to the participants via e-mail. The answers were processed in our offices in Methodist Richardson Medical Center, in Richardson, Texas which is a private tertiary medical center part of the Methodist Health System. PARTICIPANTS: Participants were all incoming HPB Fellows (In HPB fellowship programs accredited by the Fellowship Council) starting their fellowship in August 2017. RESULTS: We had a 94% response rate. Forty-six percent of fellows anticipate doing about 150 to 250 HPB cases during the fellowship, and all 15 fellows anticipate having at least 1 publication during fellowship. Despite that >90% of fellows believe that minimally invasive surgery (MIS) approaches will be more frequently utilized in HPB surgery, only 3/15 anticipate being able to apply MIS techniques and only 54% will be robotically trained. Interestingly the majority of fellows believe that the attending should be performing the case the first few months. CONCLUSION: The trainees believe that case volume is the most important factor for choosing a fellowship and for adequate training. Most of the fellows anticipate doing adequate number of cases but only the minority feels they will be adequately trained in MIS-robotic techniques.

Predictors of Hiatal Hernia Recurrence After Laparoscopic Anti-reflux Surgery with Hiatal Hernia Repair: a Prospective Database Analysis.

BACKGROUND: The aim of this study is to identify factors that can predict hiatal hernia recurrence (HHR) in patients after anti-reflux surgery with hiatal hernia (HH) repair. METHODS: A single-institution, prospectively collected database was reviewed (January 2002-October 2015) with inclusion criteria of GERD and laparoscopic anti-reflux (AR) surgery with HH repair. Demographics, esophageal symptom scores, and pre- and post-upper gastrointestinal imaging (UGI) were collected. Mesh usage, HH type (sliding, paraesophageal (HH) or type IV), and size were evaluated, and patients who had HHR versus those who did not (NHHR) were compared. Statistical analysis was performed using IBM SPSS v.23.0.0, with α = 0.05. RESULTS: Three hundred twenty-two patients met inclusion criteria. Mean age was 56.9 ± 14.8 years (60.9% female), and mean follow-up was 19.9 ± 23.8 months. 88.2% underwent total fundoplication and 11.8% underwent partial fundoplication. HHR rate was 15.5%. HHR patients had larger HH than the NHHR group. There was no significant difference between groups for age, gender, BMI, race, and mesh usage. Only 3 patients (10.3%) with HHR reported mild-to-moderate heartburn, regurgitation, and solid or liquid dysphagia at 12-month follow-up. Overall reoperation rate was 1% in this population. CONCLUSIONS: HHR is correlated with large hernia size. Mesh use and patient BMI were not predictors, and no correlation was identified between HHR and presence of GERD symptoms. Recurrence after repair is not uncommon, but is asymptomatic in most cases. Reoperation is rare and mesh is not routinely needed. Large asymptomatic HHs in the elderly often do not require intervention.

Growth in robotic-assisted procedures is from conversion of laparoscopic procedures and not from open surgeons' conversion: a study of trends and costs.

BACKGROUND: Utilization of laparoscopy (LAP) has been increasing in general surgery for years, and there is currently a rapid increase in the utilization of robotic-assisted surgeries (RAS). This study evaluates trends in the surgical approach utilized in some commonly performed surgeries, the proportion of each approach within the procedures, and the cost of these surgeries based on the surgical approach. METHODS: This is a retrospective study using the Vizient database. The database was queried using ICD-9 codes for colectomy, cholecystectomy, inguinal and ventral hernia repairs, and bariatric surgeries, either open, LAP, or robotically performed. Utilization trends were evaluated between quarters, over a 7-year period, and direct cost was compared between approaches. IBM SPSS v.23.0.0 was used for data analysis, with α = 0.05. RESULTS: 857,468 patients underwent colectomy, cholecystectomy, inguinal and ventral hernia repairs, and bariatric procedures. A significant decrease in open-approach utilization was seen in colectomy (71.8-61.9%), cholecystectomy (35.7-27.1%), and bariatric surgeries (20.1-10.1%), whereas both LAP and RAS utilization increased (p < 0.001). Significant RAS increase was seen in all five procedures: colectomy (0.4-8.0%), cholecystectomy (0.2-1.8%), IHR (19.9-29.4%), VHR (0.2-2.9%), and bariatric (0.6-5.4%), compared to a decrease in LAP (p < 0.001). Surgery cost was significantly higher for open ($14,364), followed by RAS ($11,376) and LAP ($7945), p < 0.001. CONCLUSIONS: Robotic technology is commonly viewed as enabling open procedures to be converted to minimally invasive, a trend not observed in our study. Our trends analysis revealed significant RAS utilization increase from LAP procedures and not from open procedure conversion, although specific surgeon data were not available. RAS were costlier than LAP for all five procedures. The benefits of rapid robot adoption and the forces that are driving these must be examined against a backdrop of burdening an already expensive healthcare system.

Case report of intestinal non-rotation, heterotaxy, and polysplenia in a patient with pancreatic cancer.

RATIONALE: Heterotaxy with polysplenia is an extremely rare congenital condition resulting from abnormal arrangement of organs in the abdominal and thoracic cavities during embryologic development. When a malignancy such as pancreatic cancer develops under these conditions, surgical resection becomes particularly complex. This case report demonstrates successful pancreatic cancer resection despite the patient's complicated anatomy. PATIENT CONCERNS: An 82-year-old female presented to our institution with complaints of mild right upper quadrant pain radiating to the mid-epigastric region. DIAGNOSES: Physical examination revealed jaundice with scleral icterus consistent with obstructive jaundice. Radiographic imaging revealed hepatic duct dilation with several anatomic anomalies including small bowel location in the right upper abdomen, cecum, and appendix in the left lower quadrant, reversed superior mesenteric artery and superior mesenteric vein positions, and right-sided duodenal-jejunal flexture as well as an entirely right-sided pancreas, and left lower pelvis with ≥6 separate splenules. These findings resulted in a diagnosis of heterotaxy syndrome with polysplenia. INTERVENTIONS: Careful preoperative planning and total pancreatectomy was performed without complication. OUTCOMES: The patient recovered well. Pathologic examination of the pancreatic mass revealed moderately/poorly differentiated invasive pancreatic duct adenocarcinoma. The patient remains alive and well without signs of recurrent disease at the 2-year follow-up. LESSONS: Given the wide range of anatomical variants observed in patients with heterotaxy syndrome, a thorough radiologic assessment is necessary before engaging in any surgical procedure. In our case, preoperative identification of the various anatomic anomalies, such as the short and vertically oriented pancreas, the porta hepatis position anterior to the duodenum, the nonrotation of the intestines and the anomalous origin of the right hepatic artery allowed us to perform a safe and uncomplicated total pancreatectomy.

Beyond the learning curve: incidence of bile duct injuries following laparoscopic cholecystectomy normalize to open in the modern era.

BACKGROUND: Early reports of higher complication rates, specifically bile duct injuries, raised concerns over the safety of laparoscopy over open cholecystectomy. This study aims to ascertain the rate, management, and perioperative outcomes of bile duct injury in an era beyond the laparoscopic learning curve. METHODS: The New York State (NYS) Planning and Research Cooperative System longitudinal administrative database was used to identify patients. From 2005 to 2010, 156,315 patients were identified who had undergone laparoscopic cholecystectomy for symptomatic cholelithiasis or acute or chronic cholecystitis. Patients were then tracked with unique identifiers for common bile duct injury. Common bile duct injury was identified by ICD-9 and CPT diagnosis and procedure codes for patients who subsequently underwent hepatectomy, hepaticojejunostomy, or other bile duct surgery. RESULTS: From 2005 to 2010, 156,958 patients were identified who had undergone laparoscopic cholecystectomy for symptomatic cholelithiasis or acute or chronic cholecystitis. Of the total patients, 149 patients underwent a biliary duct procedure within a year. Twenty-four of them were diagnosed with gallbladder cancer and excluded, leaving 125 for further analysis. The biliary injuries were identified at a rate of 0.080 %. Thirty-one of those patients (24.8 %) underwent hepatectomy, 40 patients (32.0 %) underwent hepaticoenterostomy, and 54 patients (43.2 %) underwent primary repair of the bile duct. Thirty-two (26 %) patients were repaired on the same day of their initial procedure. Of the remaining 93 patients, 38 (30 %) were repaired within 10 days, seven (6 %) repaired between 11 and 20 days, and 48 (38 %) patients over 21 days from injury. CONCLUSION: In NYS, the rate of bile duct injury has now decreased to 0.08 % and mirrors the historical figures quoted for open cholecystectomy. This improvement likely reflects increased experience, improved instrumentation, and movement beyond the "learning curve."

Creation of gastric conduit free-graft with intraoperative perfusion imaging during pancreaticoduodenectomy in a patient post esophagectomy.

As surgery becomes more successful for complicated malignancies, patients survive longer and can unfortunately develop subsequent malignancies. Surgical resection in these settings can be treacherous and manipulations of the patient's anatomy need to be closely considered before embarking on major operations. We report a case of a patient who survived esophageal resection for locally advanced esophageal cancer only to develop a new pancreatic head malignancy. Careful upfront planning allowed for a successful resection with an uncomplicated recovery. She underwent open pancreaticoduodenectomy, and to maintain perfusion to the gastric conduit a microvascular anastomosis of the gastroepiploic pedicle was performed to the middle colic vessels. Intraoperative fluorescent imaging was used to evaluate the anastomosis as well as gastric and duodenal perfusion during the case.
