Surgical revision for pancreatojejunostomy stricture: a case series of 14 patients.

BACKGROUND: Pancreatojejunostomy stricture (PJS) is a rare long-term complication of pancreaticojejunal anastomosis. This study aimed to investigate the role of surgery in the management of pancreatojejunostomy strictures. METHODS: The database of the Pancreas Center of Nanjing Medical University was retrospectively screened for patients who underwent a surgical revision for PJS between June 2012 and August 2019, and their clinical characteristics and management modalities were reviewed. RESULTS: Fourteen consecutive cases were retrieved, the median age at index operation was 41.1 years (19-71). The average time between the two operations was 70.6 months (8-270 months). Index procedures included pancreaticoduodenectomy (PD) (7/14, 50%), pylorus-preserving PD (4/14, 28.6%), Berger procedure (2/14, 14.3%), and middle pancreatectomy (1/14, 7.1%). The diameter of the main pancreatic duct was < 4 mm in all 14 cases, and nine underwent pancreaticojejunostomy (PJ) stenting during the index operation. The most frequent complaints were abdominal pain (6/14, 42.9%), recurrent acute pancreatitis (6/14, 42.9%), pancreatic fistula (1/14, 7.1%), and abdominal distention (1/14, 7.1%). The diagnosis of PJ stricture was confirmed by computed tomography or magnetic resonance imaging in all cases. All patients had a main duct diameter > 5 mm before surgical revision. All patients underwent wedge excision with interrupted one-layer suturing with absorbable sutures and without stent placement. In this series, only one patient required reoperation. Upon follow-up, 11 of 12 patients had complete resolution of the PJ stricture. CONCLUSION: PJS is a long-term complication of pancreatojejunostomy. Surgical revision of the anastomosis is a safe and effective treatment modality.

Evaluation of Twenty-One Cases of Abdominal Tuberculosis: A Single-Center Experience.

Background: Abdominal tuberculosis (TB) remains an issue as it masquerades as many malignant or benign abdominal conditions. Objective: To analyze the clinical and laboratory features of abdominal TB retrospectively and discuss its management. Methods: The data of patients with a histopathologic diagnosis of abdominal TB seen from January 1, 2008, to February 1, 2019 were collected in The First Affiliated Hospital of Nanjing Medical University. Nodal, visceral, peritoneal, and mixed TB cases were included while excluding other forms of extra-pulmonary TB (EPTB). Results: A total of 21 patients presented having a median age of 49 years (interquartile range 33-57 years) with 12 females and 9 males. Ten presented with abdominal pain, whereas four had abdominal pain and distention. Weight loss was present in five and type 2 diabetes mellitus (DM) in three. Every patient received contrast-enhanced computed tomography (CE-CT) with positive results in all the cases. Seven patients received endoscopic ultrasound-guided fine-needle aspiration cytology examination (EUS-FNAC) and five had results positive for TB. Pre-operative diagnosis of abdominal TB was possible in seven; however, the majority (n = 14) underwent exploratory laparotomy, and all obtained a definitive diagnosis of TB. No deaths occurred. Conclusions: Both CE-CT and EUS-FNAC can aid in the timely diagnosis. Laparotomy is an invasive but efficient tool for the final diagnosis of abdominal TB.

Gallbladder tuberculosis in a dialysis patient: a case-report.

BACKGROUND: The diagnosis of gallbladder tuberculosis remains elusive even to the most experienced clinicians. Our aim is to describe our experience of this rare disease, and to raise awareness of the increasing likelihood of tuberculosis in chronic kidney disease (CKD) patient. CASE PRESENTATION: We report a rare case of gallbladder tuberculosis in a chronic kidney disease patient on hemodialysis. This combination is rarely reported in literature. No signs of abdominal tuberculosis were observed besides a clinical profile consistent with CKD in our patient. The clinical signs of uremia masks those of abdominal tuberculosis and render the pre-operative diagnosis of tuberculosis more difficult. CONCLUSIONS: The clinical signs of uremia conceal those of abdominal tuberculosis. The diagnosis of tuberculosis in CKD patients hinges mainly on a high index of suspicion, perioperative findings and histological examination.

Parenchyma Preserving Surgery for Idiopathic Chronic Calcific Pancreatitis in Children: A Report of Three Cases.

Background: Idiopathic chronic calcific pancreatitis is a rare entity. Early surgical intervention and a parenchyma sparing procedure should be advocated to prevent further decay of the pancreas and the occurrence of cancer. Case Presentations: Case 1: A 14-year-old boy presented with a 3-year history of right upper abdominal pain that has been aggravated in the last 2 months. Imaging revealed a dilated pancreatic duct of 6 mm with pancreatic duct stones in the head of pancreas. He underwent a Frey's procedure. Unfortunately, he was discharged with grade B pancreatic fistula. Case 2: A 12-year-old boy presented with a 1-year history of dull and recurring epigastric pain. Imaging studies showed multiple stones in a 12 mm dilated pancreatic duct. The patient underwent a modified Puestow procedure. Up to the 42th month follow-up, the patient had no pain complaints. Case 3: A 12-year-old boy with a 1-week history of a dull epigastric pain presented with with multiple stones in a 10 mm duct. He underwent a modified Puestow procedure and was discharged with alleviated pain. Conclusions: "Conservative" surgery allows satisfactory pancreatic duct drainage, reduced rehospitalizations, and longer pain relief than alternative endoscopic procedures.
