In February 2020, the American College of Gastroenterology (ACG) published the latest guideline on chronic pancreatitis, and put forward practical recommendations on the etiology, natural history, diagnosis, treatment, prognosis and follow-up of chronic pancreatitis. This paper aims to provide references for the diagnosis and treatment of chronic pancreatitis in China by interpreting the main content of the guideline and comparing it with related guidelines or consensuses domestically and abroad.
Objective To elucidate the clinical features and treatment of parapneumonic effusions ( PPE) . Methods Ninety-seven patients were analyzed retrospectively in Guangzhou First Municipal People’s Hospital fromJanuary 2004 to July 2008. The data of 54 patients with complicated parapneumonic effusion ( CPPE) and 9 cases with empyema were compared with 49 patients with tuberculosis pleural effusions. Results Of 97 cases, 34 patients with uncomplicated parapneumonic effusion ( UPPE) were treated with antibiotics only, whose hospitalization time was ( 14. 8 ±7. 6) days, and 27 cases were cured ( 79. 4% ) . Of 54 CPPE patients, 42 were treated with antibiotics and pleural space drainage with central venous catheter, whose hospitalization time was ( 21. 7 ±13. 0) days, and 32 were cured ( 76. 2% ) . Another12 CPPE patients were treated with interapleural urokinase and drainage from the chest tube, whose hospitalization time was ( 22. 5 ±9. 3) days, and 8 were cured ( 66. 7% ) . Nine cases with empyema were rinsed the pleural with metronidazole solution, whose hospitalization time was ( 25. 7 ±17. 4) days, and 8 were cured( 89. 0% ) . Compared with the tuberculous pleurisy patients, most CPPE and empyema occurred in middle and old aged patients with an average age of ( 63. 3 ±19. 3) years. Polykaryocyte and lactate dehydrogenase increased significantly. Adenosine deaminase ( ADA) was lt; 45 U/L in most UPPE and empyema patients, but was gt; 45 U/L in 7 cases ( 11% ) . Conclusions UPPE is simple and preferably treated with antibiotics alone. While CPPE and empyema should be drainaged as early as possible, and the low-dose urokinase may be helpful. The level of ADA can not absolutely distinguish parapneumonic effusion from tuberculous pleural effusion.
Objective To summarize the treatment experience for concomitant diseases of other abdominal organs in laparoscopic cholecystectomy （LC）. Methods The clinical data of 176 patients with LC and concomitant diseases of other abdominal organs were analyzed retrospectively， including preoperatively diagnosed cases （such as 53 with liver cyst， 15 with choledocholithiasis， 7 with chronic appendicitis， 5 with inguinal hernia， 4 with renal cyst， and 6 with ovarian cyst） and intraoperatively diagnosed cases （such as 72 with abdominal cavity adhesion， 4 with internal fistula between gallbladder and digestive tract， 3 with Mirizzi syndrome， and 7 with unsuspected gallbladder carcinoma）. Results All the operation were successfully completed in 176 patients without severe complications， including 53 cases treated with LC plus fenestration of hepatic cyst， 15 with choledocholithotomy， 7 with appendectomy， 5 with tension free hernia repair， 4 with renal cyst fenestration， 6 with oophorocystectomy， 72 with adhesiolysis， 3 with fistula resection plus intestine neoplasty， 2 with intraoperative cholangiography plus choledocholithotomy， 5 with LC plus gallbladder bed complete burning， and 4 cases treated with conversion to open surgery （1 with intestinal fistula repair， 1 with choledocholithotomy， and 2 with radical resection for gallbladder carcinoma）. Conclusions It is safe and effective to treat gallbladder diseases complicated with other concomitant diseases simultaneously with laparoscopic operation， if the principles of surgical operation are followed and the indications and applicable conditions are strictly followed. And conversion to open surgery is necessary.
【Abstract】 Objective To analyze the lung pathological features of type A H1N1 influenza and respiratory failure. Methods The data of imaging and aspiration lung biopsy of five patients with type A H1N1 influenza and respiratory filure since October 2009 were retrospectively analyzed. Results Common clinical manifestations of patients with type A H1N1 influenza and respiratory failure were rapid progress of illness after common cold-like symptoms with high fever, dyspnea, severe hypoxemia, large amounts of bloody sputum, wet rales over both lungs, and with other organs involved or even septic shock. Early lung pathological features were inflammatory exudate in alveoli and lung interstitium, infiltration of inflammatory cells, and extensive hemorrhage. Middle and late pathological features were hyperplasia of alveolar epithelial,disconnection of alveolar septa, replaced of alveolar spaces by fibrosis. Conclusions The pathology of patients with type A H1N1 influenza and respiratory failure is similiar with ARDS. Development of treatment strategies targeted to pathological characteristics of ARDS caused by type A H1N1 influenza is of greatsignificance for effective and timely treatment.
ObjectiveTo investigate the diagnosis and treatment of pancreatic cystic neoplasm. MethodsThe clinical data of 40 cases of pancreatic cystic neoplasm from October 2001 to October 2013 in our hospital were retrospec-tively analyzed. ResultsPatients with pancreatic cystic neoplasm had no specific clinical feature. Ultrasonography and computed tomography displayed a cystic tumor in 57.5%(23/40) and 72.5%(29/40) of all patients, respectively, but could not distinguish the histological types. All of the patients had been operated, among them 2 cases were misdia-gnosed as pseudocysts and internal drainage; another 38 patients were undergoing the distal pancreatectomy. Pathologic examination results after operation showed 23 cases of serous cystadenoma, 9 cases of mucinous cystadenoma, 3 cases of intraductal papillary mucinous adenoma, and 5 cases of mutinous cystadenocarcinoma. Thirty five patients were followed-up. The followed-up time range from 2 months to 8 years, verage(74.2±12.8) months. Among the 3 patients with mucinous cystadenocarcinoma, 1 patient alived with no evidence of recurrence, the other 2 patients died of tumor invasion and metastasis in 4 months and 7months after operation. The others were still alive now with no evidence of recurrence. ConclusionSurgical resection is the most effective treatment for pancreatic cystic tumor, even if the patients with no any symptoms.

Prevention and treatment of traumatic neuroma by implanting the proximal neural stump into the muscle were studied. Sixteen SD rats were used for the experimental study. The proximal stump of the left sciatic nerve was implanted into the nearby muscle as the experiment side, whereas the proximal stump of the right sciatic nerve was left untreated as the control side. The results were assessed with histological and electrophysiological methods. The experiment demonstrated that neuroma was formed in the control side one month postoperatively, whereas in the experimental side the nerve fibers were dispersed among the muscle fibers and no definite neuroma was formed. Implantation of neural stump into muscle could prevent and treat traumatic neuroma.
Objective To summarize the current diagnostic and therapeutic advancement of solid pseudopapillary tumor of the pancreas. Methods Relevant literatures about the diagnosis and treatment of solid pseudopapillary tumor of the pancreas, which were published recently domestic and abroad were collected and reviewed. Results Solid pseudopapillary tumor of the pancreas is now considered to be a low-grade malignancy with characteristic clinical, imaging and pathological features. Resection is considered to be the optimal choice with favourable prognosis. Conclusion An awareness of the features may guide us to a correct diagnosis and treatment of this rare neoplasm, but the deep understanding of the disease needs the accumulation of more cases and fundamental research.
Objective To review the progress in the mechanism of injury, diagnosis, classification, and treatment method of Lisfranc injury. Methods Recent l iterature concerning the mechanism of injury, classification, diagnosis, and treatment method of Lisfranc injury was extensively reviewed, analyzed, and summarized. Results Because of the compl icate anatomy and high missed diagnosis rate, CT imaging were often recommended for diagnosis, and MRI could be used if necessary. The current recommendations for internal fixation included the use of Kirschner wires, cannulated screws, absorbablescrews, and plate. Conclusion Classification according to the columnar theory is significant for cl inical guiding. With thecl inical appl ication of internal fixation materials, more choices were provided, which make patients get the best effect.
