Comparison of the minimally invasive treatments of laparoscopic and endosopic for common bile duct stones after gastrojejunostomy / 北京大学学报(医学版)

OBJECTIVE@#To explore the feasibility and to compare the merits and demerits of laparoscopic and endoscopic approach in removing common bile duct stones in patients with gastrojejunostomy after gastrectomy.@*METHODS@#Between January 2012 and December 2016, 25 patients with common bile duct stones after gastrojejunostomy received laparoscopic or endoscopic treatment in our centers. They were divided into laparoscopic group and endoscopic group based on treatment approaches for common bile duct stones, including 15 patients in laparoscopic group and 10 in endoscopic group. The clinical characteristics and outcomes between the two groups were retrospectively analyzed.@*RESULTS@#Among the 25 patients with gastrojejunostomy, the method of reconstruction was Billroth II in 21 patients and Roux-en-Y in 4 patients. Six patients received laparoscopic or endoscopic treatment during the acute cholangitis state. Among the laparoscopic group, 5 patients with stones more than 1 cm, 7 patients with multiple stones, while in the endoscopic group, 3 patients with stones more than 1 cm and 4 patients with multiple stones. Fourteen patients in the laparoscopic group with coexisting gallbladder stones, and 6 of their common bile duct stones were successfully removed by transcystic approach without T tube drainage. Stone removals were successful in 4 patients of the endoscopic group by a single performance, including 3 patients with single small stone and one patient with multiple small stones. Two patients in the laparoscopic group were converted to open surgery for severe adhesion and one patient in the endoscopic group turned to laparoscopic operation for failing of finding papilla in the Roux-en-Y anastomotic status. The median hospital stays were 12 d and 10 d, respectively in the laparoscopic and endoscopic group. There were 3 patients with postoperative complications, including one patient with paralytic ileus in the laparoscopic group and 2 patients with biliary pancreatitis or bacteremia in the endoscopic group, and all of them recovered uneventfully with conservative treatment.@*CONCLUSION@#Both laparoscopic and endoscopic approaches are feasible for removing stones in the common bile duct in patients with gastrojejunostomy after gastrectomy, and they complement each other. In addition, both techniques are difficult to conduct, and a technical competence should be considered in selection of each method.

Strategies for diagnosis of xanthogranulomatous cholecystitis masquerading as gallbladder cancer / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Patients with xanthogranulomatous cholecystitis sometimes exhibit imaging and intraoperative findings that are similar to those of advanced gallbladder cancer, thus these patients are easily misdiagnosed. The present study aimed to investigate the characteristics of xanthogranulomatous cholecystitis masquerading as gallbladder cancer that could potentially aid in the correct diagnosis of this condition.</p><p><b>METHODS</b>The clinical, serological, radiological and operative features of twelve patients with obviously wall-thickening or mass-forming xanthogranulomatous cholecystitis were retrospectively analyzed. Additionally, the patient preoperative features were compared to those of 36 patients with advanced gallbladder cancers.</p><p><b>RESULTS</b>Twelve patients with xanthogranulomatous cholecystitis exhibited one to three episodes of acute cholecystitis within 0.5 to 7 months prior to admission to the hospital. Five of these patients exhibited concomitant choledocholithiasis, whereas no concomitant choledocholithiasis was identified in patients with advanced gallbladder cancer. The incidence of abdominal pain (χ(2) = 6.588, P = 0.010), acute cholecystitis (χ(2) = 29.176, P = 0.000), acute cholangitis (χ(2) = 6.349, P = 0.012), choledocholithiasis (χ(2) = 16.744, P = 0.000), carcinoembryonic antigen test (P = 0.007), CA125 (P = 0.001), and diffuse gallbladder wall thickening (χ(2) = 6.031, P = 0.014), continued mucosal line (χ(2) = 15.745, P = 0.000), homogeneous enhancement of mucosal line (χ(2) = 19.947, P = 0.000), submucosal hypoattenuated nodules or band (χ(2) = 18.607, P = 0.000) in computed tomography demonstrated statistically significant differences between cases of xanthogranulomatous cholecystitis and gallbladder cancer. Furthermore, all the twelve patients with xanthogranulomatous cholecystitis exhibited at least one positive computed tomography imaging feature aside from past acute cholecystitis episode, and no patient with advanced gallbladder cancer simultaneously exhibited past acute cholecystitis episode and at least one positive computed tomography imaging feature.</p><p><b>CONCLUSIONS</b>The accurate preoperative diagnosis of xanthogranulomatous cholecystitis includes an integrated review of past acute cholecystitis episode, choledocholithiasis, and positive computed tomography imaging features. Besides, we present an algorithm for intraoperative diagnosis.</p>

Correction of claw hand deformity after burns by elastic traction / 中华整形外科杂志

<p><b>OBJECTIVE</b>To investigate a new method for correction of claw hand deformity after burns.</p><p><b>METHODS</b>From May 2006 to Jul. 2010, 12 patients with claw hands deformities after burns were treated with skin grafts (11 hands) and skin flap (1 hand) with unsatisfactory results. Then elastic traction (skin traction or skeletal traction) were performed with individual functional brace.</p><p><b>RESULTS</b>All patients were followed up for 0.5 to 2 years. Elastic traction was effective in the correction of metacarpophalangeal joint deformity, buttonhole deformity, thumb-in-palm deformity, scar contracture, and palmar arch deformity.</p><p><b>CONCLUSIONS</b>Elastic traction is a simple and effective way for the correction of claw hand deformity after burns with less morbidity and stable results.</p>

Long-term outcomes of choledochoduodenostomy for hepatolithiasis / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Oddi sphincter plays an important role in preventing reflux cholangitis. There exists the controversy on application of choledochoduodenostomy in hepatolithiasis management. The present study aimed at evaluating long-term outcomes of choledochoduodenostomy for the treatment of hepatolithiasis.</p><p><b>METHODS</b>Forty-six consecutive cases of hepatolithiasis who underwent choledochoduodenostomy were analyzed retrospectively. The pre- and postoperative rates of recurrent cholangitis and acute cholangitis severe type were compared. Paired chi-square test was applied.</p><p><b>RESULTS</b>The mean follow-up time was 17.3 years ranging from 1.6 to 40 years with a follow-up rate of 97.8% (45/46). High rates of remnant stones (39.1%, 18/46), recurrent stones (31.1%, 14/45), uncorrected strictures (85%, 17/20), and mortality (24.4%, 11/45) were observed in this group. Regurgitation of food debris and duodenal content into the biliary tract through the anastomosis was observed. The rate of recurrent cholangitis was equal to the preoperative period (93.3%, 42/45). The rate of acute cholangitis severe type after choledochoduodenostomy (46.7%, 21/45) increased significantly (P<0.01) when compared to the preoperative period (20.0%, 9/45).</p><p><b>CONCLUSIONS</b>Choledochoduodenostomy did not entirely achieve the goal of clearance of stones, correction of strictures, and removing of hepatobiliary lesions by itself. Choledochoduodenostomy without cholangioplasty resulted in an increase of severe reflux cholangitis due to the loss of the anti-reflux function of the sphincter of Oddi. Therefore, choledochoduodenostomy is not an ideal approach to reduce cholangitis in hepatolithiasis and is not the best choice in the management of hepatolithiasis.</p>

Clinical effects of subcutaneous tunnel hepatocholangioplasty on the treatment of hepatolithiasis / 中华外科杂志

<p><b>OBJECTIVE</b>To evaluate the therapeutic effect of subcutaneous tunnel hepaticoplasty on the treatment of hepatolithiasis.</p><p><b>METHODS</b>The early complications and clinical effects of 99 hepatolithiasis cases who underwent subcutaneous tunnel hepaticoplasty from January 1993 to August 2006 were analyzed retrospectively. The stones of 28 (28.3%) patients were in the left lobe, 24.2% (24/99) in the right, and 47.5% (47/99) in bilateral lobe. Sixty-six patients (66.7%) had both stones and biliary strictures. During the procedure, a portion of the liver habouring stone was resected if necessary. The hepatic duct and strictures were opened, the stones were removed, and the porta hepatis was repaired by one end of a segment of jejunum. The other end of the jejunum was set subcutaneously. The gall bladders of 27 patients (27.3%) were used as subcutaneous tunnel instead.</p><p><b>RESULTS</b>Ninety-five out of ninety-nine cases were followed up with an average of 4.2 years (1 month to 13.5 years). The rates of residual stone, recurrent stone and cholangitis were 23.2% (23/99), 20.0% (19/95) and 14.7% (14/95) respectively. Postoperatively, 34 cases who had residual or recurrent stones were underwent lithotomy by choledochoscope through the subcutaneous blind loop and the achievement ratio was 91.2% (31/34).</p><p><b>CONCLUSIONS</b>Subcutaneous tunnel hepatocholangioplasty decreases the relapsing cholangitis effectively, and makes an easy way to take out residual or recurrent stones.</p>

Prognostic analysis of T1 and T2 stage gallbladder cancer with invasion within the gallbladder wall / 中华外科杂志

<p><b>OBJECTIVE</b>To explore the impact of different treatment procedure on the prognosis of T1 and T2 stage gallbladder cancer with the invasion within the gallbladder wall.</p><p><b>METHODS</b>A retrospective analysis was conducted on 45 patients with pathologic stage T1 and T2 gallbladder cancer who had undergone surgical resection from 1990 and 2005.</p><p><b>RESULTS</b>Depth of invasion (T), radical cholecystectomy and postoperative adjuvant chemotherapy were independent prognostic factors on Cox multivariate analysis. The 5-year survival rates of patients with T1a, T1b and T2 stage gallbladder cancer who underwent simple cholecystectomy without postoperative adjuvant chemotherapy were 100%, 67% and 0, respectively. The survival rate in T2 was significantly lower than those in T1a and T1b. Without postoperative adjuvant chemotherapy, the 5-year survival rates of patients with T2 stage gallbladder cancer who underwent simple cholecystectomy and radical cholecystectomy were 0 and 63%, respectively. There was significant difference between the survival time of T2 patients who had undergone simple cholecystectomy with and without postoperative adjuvant chemotherapy.</p><p><b>CONCLUSIONS</b>The prognosis of patients with T1 stage gallbladder cancer is much better than that of T2 stage. The 5-year survival rates of patients with T1a and T1b stage gallbladder cancer who received simple cholecystectomy are relatively good. Radical cholecystectomy and postoperative adjuvant chemotherapy can improve the prognosis of patients with T2 gallbladder cancer.</p>
