[Treatment of hepatolithiasis by multiple operative methods with hepatico-subcutaneous stoma].

OBJECTIVE: To evaluate the mid-term and long-term outcomes of patients with hepatolithiasis after receiving multiple operative methods with hepatico-subcutaneous stoma. METHODS: A retrospective analysis was performed based on 156 patients with hepatolithiasis who underwent multiple operative methods with hepatico-subcutaneous stoma from Apr. 1993 to Mar. 2010 in Peking University Third Hospital. Thirty-seven of them had stone in the left lobe (23.7%), 22 in the right lobe (14.1%), and 97 in bilateral lobes (62.2%). Ninety-nine patients had hepatolithiasis combined with biliary stricture (63.5%). RESULTS: All of the patients underwent successful operations and recovered well with no death in perioperative period. The rate of operative complications was 35.9%. A total of 146 patients were followed up with a median time of 7 years. The rate of patients with cholangitis, recurrent stone, and biliary stricture newly detected was 13.0% (19/146), 21.9% (32/146) and 8.2% (12/146), respectively. Draining inflammatory bile and taking out recurrent stones by hepatico-subcutaneous stoma were carried out in 35 patients (24.0%). CONCLUSION: Treatment of hepatolithiasis with biliary stricture and its recurrence by multiple operative methods with hepatico-subcutaneous stoma is safe, effective, minimally invasive, and easy to perform.

[Fourier transform infrared spectroscopic study on gallbladder carcinoma].

Fourier transform infrared (FTIR) spectroscopy with an attenuated total reflection(ATR) probe was used to study the benign and malignant tissues of gallbladder. FTIR spectra of 18 tissues of gallbladder carcinoma and 139 benign tissues were collected and analyzed. The results demonstrated that bands related to lipid, carbohydrate, and nucleic acid from malignant samples were significantly different from those of benign ones: (1) The peak positions of 1 167 and 1 123 cm(-1) shifted toward lower wave number (P < 0.05) but that of 1 309 cm(-1)' to the higher one (P < 0.05); (2) The relative intensity ratios of I2 856/I1 461, I1 167/ I1 461, I1 123/I1 461, I1 082/I1 461, increased significantly (P < 0.05) (3) The half-widths of 1 167 and 1 082 cm(-1) increased significantly (P < 0.05), whereas the half-width of 1 461 cm(-1) decreased significantly (P < 0.05). (4) The probability of 1 750 cm(-1) band of gallbladder carcinoma tissues increased significantly (P < 0.05).

(2) The relative intensity ratios of I(1546)/I(1460), I(1250)/I(1460), I(1120)/I(1460), I(1080)/I(1460) were significantly increased (P < 0.05). (3) The presence rate of band of 1340 cm(-1) was significantly decreased (P < 0.05). CONCLUSION: FTIR surface spectra may become a novel powerful non-invasive approach of detecting thyroid cancer in regular routine check-up.

[Investigation on Fourier transform infrared spectrum of freshly resected cholangiocarcinoma tissue].

To explore the feasibility of quick intraoperative in situ and noninvasive diagnosis of cholangiocarcinoma by Fourier transform infrared (FTIR) spectroscopy, 26 samples of freshly resected cholangiocarcinoma tissues and 43 samples of benign bile duct tissue were collected during surgery. And all fresh samples were measured by FTIR spectroscopy via probe of attenuated total reflection (ATR) without pretreatment immediately after resection. For each spectrum, 12 bands were identified and assigned between 3 800 and 1 000 cm(-1). The peak position was found, and the intensity and area of the bands were measured; The ratios of the intensity and area were calculated. Standard statistic analysis was performed. The results illustrated that the FTIR spectra of malignant tissue were significantly different from those of benign tissue: 1. The bands related to lipid: The peak of 2 925 cm(-1) shifted to lower wave number significantly (P = 0.033); 2. The bands related to nucleic acid and lipids: the ratios of I1 083/ I1 460 (P = 0.005), S1 083 /S1 460 (P = 0.001) and S1 240/S1 460 (P = 0.025) raised significantly, indicating that the relative quantity of nucleic acid to lipids had evidently increased in malignancy. 3. The bands related to protein: The ratios of I1 550/I1 083 (P = 0.000) and S1 550/S1 083 (P = 0.000) reduced significantly, implying that the relative quantity of protein to nucleic acid in malignancy decreased significantly and the secondary structure of protein changed probably. Our primary result illustrated that the FTIR spectroscopy technique maybe a promising method for in situ and quick intraoperative diagnosis of cholangiocarcinoma and has great value for clinical application.

[Investigation on Fourier transform infrared spectrum of metastatic lymph node in thyroid cancer].

The aim of the study is to explore the possibility of detecting metastatic lymph nodes by FTIR spectra during the surgery of thyroid cancer. The FTIR spectra of 20 metastatic lymph nodes and 69 non-metastatic ones were collected via an ATR (attenuated total reflectance) probe. For each spectrum, 28 variables of 13 bands including peak positions and relative intensities were measured. The variables of metastatic lymph node were compared to those of non-metastatic ones using standard statistic methods. The results indicated that the FTIR spectra of metastatic lymph nodes were significantly different from non-metastatic ones in the bands related to protein, lipid, nucleic acid and carbohydrate. (1) Variations of bands related to protein: The relative intensity ratios of I3 280 /I1 460, I1 640 /I1 460 and I1 546/I1 460 increased significantly (P < 0.05); (2) Variations of bands related to lipid: The relative intensity ratios of I1 743 /I1 460 decreased significantly (P < 0.05). On the contrary, I 400 /I1 460 increased significantly (P < 0.05); (3) The peak positions of 1 165 and 1 120 cm(-1) which were all assigned to carbohydrate shifted toward higher wave number (P < 0.05). The relative intensity ratio of I1 165 /I1 460 decreased significantly (P < 0.05); (4) The peak positions of 1 085 cm(-1) related to nucleic acid shifted to the lower wave number (P < 0.05); (5) Other undetermined bands: The relative intensity ratios of I1 303 /I1 460 and I1 303 /I1 240 increased significantly (P < 0.05). FTIR spectroscopy could be a reliable and practicable method for metastatic lymph nodes diagnosis in the operation of thyroid cancer. It could be applied in detecting metastatic lymph nodes which can not be determined by palpation in surgery.

Can pigment gallstones be induced by biliary stricture and prevented by medicine in Guinea pigs?

AIM: To determine the relationship between biliary stricture and pigment gallstone formation, and the prevention of pigment gallstones with medicine. METHODS: One hundred and eighteen male guinea pigs were randomly divided into four groups: stricture group (S, n = 30) underwent partial ligation of common bile duct, and fed on regular chow; S plus medicine group (S+M, n = 27) underwent the same operation but fed on medicinal chow (0.3 g chenodeoxycholic acid, 0.5 g glucurolactone, and 0.5 g aspirin were mixed up in 1.2 kg regular chow); medicinal control group (C+M, n = 30) was free of operation, and fed on medicinal chow; and control group (C, n = 31) was free of operation and fed on regular chow. One week later, laparotomy was performed, and the bile of gallbladder was collected, measured, and cultured. RESULTS: Gallstones were identified. Pigment gallstones were induced by biliary stricture in 95% (22/23) of S group. In the S+M group, the incidence of gallstone was reduced to 55% (11/20, vs S group, P < 0.01). The changes of indirect bilirubin and ionized calcium in the bile were consistent with gallstone incidences. CONCLUSION: Biliary stricture can cause pigment gallstone formation in guinea pigs, and the medicines used can lower the incidence of gallstones. The bilirubin and ionized calcium play important roles in pigment gallstone formation.

[Clinical effects of subcutaneous tunnel hepatocholangioplasty on the treatment of hepatolithiasis].

OBJECTIVE: To evaluate the therapeutic effect of subcutaneous tunnel hepaticoplasty on the treatment of hepatolithiasis. METHODS: 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. RESULTS: 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). CONCLUSIONS: Subcutaneous tunnel hepatocholangioplasty decreases the relapsing cholangitis effectively, and makes an easy way to take out residual or recurrent stones.

[FTIR spectroscopic explorations of freshly resected thyroid malignant tissues].

In the present paper, 17 cases of freshly resected malignant thyroid tissue samples and 23 cases of benign thyroid tissue samples were characterized using FTIR spectroscopy with an ATR probe. Statistic analysis indicated that the FTIR spectra of cancerous tissue were significantly different from those of benign tissue. In comparison with normal tissues, the FTIR spectra of malignant thyroid tissues possess the following features: (1) Variation of bands related to protein: Amide I band shifted to lower wave number significantly (P<0.01), while amide II band shifted to higher wave number(P<0.05), and the ratios of I1640/I1460 and I1640/I1550 were raised (P<0.01). The authors can conclude that the amounts and the secondary structure of protein in malignant tissue changed. (2) The peaks at 2955, 2920, 2870, 2850 and 1740 cm(-1) appeared less frequently suggesting that the relative quantity of lipid in malignant tissue decreased significantly; (3) Variation of bands related to nucleic acid: The band of 1241 cm(-1) shifted to (1238.29+/-2.87)cm(-1), and the ratios of I1080/I1460 were raised significantly(P<0.05). The most possible reason for the changes was that the mutation of DNA and the amounts of nucleic acid had increased in malignant neoplasms. Experimental results show that the malignant thyroid tissues can be distinguished from the benign tissues by their infrared spectra. This approach proves that FTIR spectroscopy is a reliable and practicable method for thyroid cancer diagnosis in operations. The authors have expanded their research on detecting the thyroid cancer FTIR spectra via percutaneous and in vivo, and have achieved a positive result which is going to be reported in another paper.

Early diagnosis and early medical treatments are the keys to save the patients' lives and improve their living quality. Fourier transform infrared (FTIR) spectroscopy can be used to distinguish malignant from normal tissues at the molecular level. In the present paper, programs were made with chemometrics method of pattern recognition to classify unknown tissue samples. Spectral data were pretreated by using smoothing, SNV and RHM method. Cross validation was used to test the discrimination effect of KNN method. A total of 63 gastric tissue samples were employed in this study, including 26 cases of normal tissue samples and 37 cases of cancerous tissue samples. The recognition results of the KNN method showed that the correctness of classification achieved 91.7%.

Clinical application of plasma shock wave lithotripsy in treating impacted stones in the bile duct system.

AIM: To verify the safety and efficacy of plasma shock wave lithotripsy (PSWL) in fragmenting impacted stones in the bile duct system. METHODS: From September 1988 to April 2005, 67 patients (26 men and 41 women) with impacted stones underwent various biliary operations with tube (or T-tube) drainage. Remnant and impacted stones in the bile duct system found by cholangiography after the operation were fragmented by PSWL and choledochofiberscopy. A total of 201 impacted stones were fragmented by PSWL setting the voltage at 2.5-3.5 kV, and the energy output at 2-3 J for each pulse of PSWL. Then the fragmented stones were extracted by choledochofiberscopy. The safety and efficacy of PSWL were observed during and after the procedure. RESULTS: One hundred and ninety-nine of 201 impacted stones (99.0%) in the bile duct system were successfully fragmented using PSWL and extracted by choledochofiberscopy. The stone clearance rate for patients was 97% (65/67). Ten patients felt mild pain in the right upper quadrant of the abdomen, and could tolerate it well. Eleven patients had a small amount of bleeding from the mucosa of the bile duct. The bleeding was transient and stopped spontaneously within 2 min of normal saline irrigation. There were no significant complications during and after the procedure. CONCLUSION: PSWL is a safe and effective method for fragmenting impacted stones in the bile duct system.

[FTIR spectroscopic characterization of freshly removed breast cancer tissues].

OBJECTIVE: To identify the FTIR spectroscopic characterization of breast cancer and explore the possibility of application of FTIR in differentiation of malignant and benign breast lesions. METHODS: FTIR spectra of surgically removed fresh breast tissues were measured by spectrometer equipped with mid-infrared fiber optics and an ATR probe. Peaks in the spectra were measured and relative intensity ratios were calculated and analyzed if there are significant differences between the spectra of malignant and benign breast lesions. RESULTS: There were significant differences (P < 0.05) between the spectra of malignant breast cancers and benign breast tissues in the relative intensity ratios of different peaks (I1640/ I1550 and I1160/I1120 for protein structures; I1640/I1460 and I1550/I1460 for relative content of protein and lipid; I1460/I1400 for lipid structures; I1310/I1240 for nucleic acid). CONCLUSION: FTIR spectroscopy could be a useful tool in clinical diagnosis of breast cancer.

[Prognostic analysis of T1 and T2 stage gallbladder cancer with invasion within the gallbladder wall].

OBJECTIVE: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

In vivo and in situ detection of colorectal cancer using Fourier transform infrared spectroscopy.

AIM: Real-time and rapid identification of the malignant tissue can be performed during or before surgical operation. Here we aimed to detect in vivo and in situ colorectal cancer by using Fourier transform infrared (FTIR) spectroscopy and fiber-optic technology. METHODS: A total of five patients with large intestine cancer were detected in vivo and in situ. Of them, three cases of colon cancer and one case of cecum cancer were detected intraoperatively and in vivo by using a FTIR spectrometer during surgical operation, and one case of rectum cancer was explored non-invasively and in vivo before the surgical operation. Normal and malignant colorectal tissues were detected in vivo and in situ using FTIR spectroscopy on the basis of fundamental studies. RESULTS: There were significant differences between FTIR spectra of normal and malignant colorectal tissues detected in vivo and in situ. Experimental results revealed that the spectral characteristics of normal and malignant tissues found in vivo and in situ were similar to those obtained from in vitro measurement in our previous fundamental research. CONCLUSION: FTIR fiber-optic attenuated total reflectance (ATR) spectroscopy can identify in situ and in vivo colorectal cancer. FTIR spectroscopic method with fiber optics is a non-invasive, rapid, accurate and in vivo cancer detection technique in clinical diagnosis.

[Nodular goiter surface detection by FTIR spectroscopy].

A novel non-invasive diagnosis method of nodular goiter is proposed in the present study by recording FTIR spectra on the skin overlying thyroids using fiber optical technique and attenuated total reflection probe. FTIR spectra from 20 nodular goiters and 34 normal controls were collected. Twenty seven spectral variables of 13 bands including peak position and relative intensities were extracted from the FTIR spectra so that statistic work could be conducted using SPSS. The results demonstrate that peak positions of 2 925 and 1 250 cm(-1) both shifted toward lower wave number (P < 0.05) in the FTIR spectra of nodular goiter. The relative intensity ratios of H1 740/H1 460, H1 160/H1 460, and H1 160/H1 120 decreased significantly in FTIR spectra of nodular goiter (P < 0.05). Inversely, H1 080/H1 460 increased significantly (P < 0.05) in nodular goiter. The above statistic differences suggest that nodular goiter may produce some characteristic chemical substance which can diffuse onto the surface of skin and therefore be detectable using FTIR spectroscopy with fiber optic techniques. These differences are the basis of diagnosing nodular goiter by FTIR surface detection.

[Novel infrared spectroscopy methods for clinical diagnosis of tumor].

In this paper, the authors have reviewed their investigation on the clinical detection of tumor tissues by infrared spectroscopy in recent ten years. Based on the comparison of different IR spectroscopic methods such as IR transmission spectroscopy, micro-IR spectroscopy etc, the authors found the good consistency of the results of ATR (attenuated total reglection) IR spectroscopic method with those of pathological biopsy. The authors have directly measured the IR spectra of frozen tissues stored in liquid nitrogen and freshly resected tissues, and have realized the measurement of tumor tissues in vito during the operation process using a specially designed IR spectrometer connected with a mid-IR fiberoptic with an ATR probe. The authors have investigated the malignant and normal tissues including parotid, esophagus, stomach, colon, liver, gallbladder, breast, thyroid etc. and compared with the pathological results. The accuracy of this novel IR detection method is more than 90%.

[FTIR spectroscopic explorations of clinical practice of breast cancer].

Nineteen variables of thirteen bands in the spectra were compared using standard statistic methods. The results demonstrated that bands of protein, lipid, carbohydrate, and nucleic acid from cancerous samples were significantly different from those from normal ones: (1) The relative intensity of N-H band increased and amide I band shifted to lower wave number significantly; (2) Symmetric and antisymmetric vibrations of -CH2 group, C=O vibration, and relative intensity of (-CH2)n decreased; (3) The intensity of 1160 cm(-1) band was much weaker than that of 1120 cm(-1); (4) The band of P=O or P-O-C shifted toward lower wave number. The authors believe that FTIR spectroscopy has a promising future in breast cancer diagnosis.

Oddi sphincter preserved cholangioplasty with hepatico-subcutaneous stoma for hepatolithiasis.

AIM: To evaluate the long-term outcomes of Oddi sphincter preserved cholangioplasty with hepatico-subcutaneous stoma (OSPCHS) and risk factors for recurrence in hepatolithiasis. METHODS: From March 1993 to December 2012, 202 consecutive patients with hepatolithiasis underwent OSPCHS at our department. The Oddi sphincter preserved procedure consisted of common hepatic duct exploration, stone extraction, hilar bile duct plasty, establishment of subcutaneous stoma to the bile duct. Patients with recurrent stones can undergo stone extraction and/or biliary drainage via the subcutaneous stoma which can be incised under local anesthesia. The long-term results were reviewed. Cox regression model was employed to analyze the risk factors for stone recurrence. RESULTS: Ninety-seven (48.0%) OSPCHS patients underwent hepatic resection concomitantly. The rate of surgical complications was 10.4%. There was no perioperative death. The immediate stone clearance rate was 72.8%. Postoperative cholangioscopic lithotomy raised the clearance rate to 97.0%. With a median follow-up period of 78.5 mo (range: 2-233 mo), 24.8% of patients had recurrent stones, 2.5% had late development of cholangiocarcinoma, and the mortality rate was 5.4%. Removal of recurrent stones and/or drainage of inflammatory bile via subcutaneous stoma were conducted in 44 (21.8%) patients. The clearance rate of recurrent stones was 84.0% after subsequent choledochoscopic lithotripsy via subcutaneous stoma. Cox regression analysis showed that residual stone was an independent prognostic factor for stone recurrence. CONCLUSION: In selected patients with hepatolithiasis, OSPCHS achieves excellent long-term outcomes, and residual stone is an independent prognostic factor for stone recurrence.

[Comparison of efficacy between ceftriaxone and cefoperazone plus sulbactam in peri-operative treatment of acute suppurative cholangitis].

OBJECTIVE: To compare the efficacy of ceftriaxone and that of cefoperazone plus sulbactam (sulperazon) in controlling infection, in scavenging bacteria from bile, and in their costs when treating acute suppurative cholangitis with choledochostomy. METHODS: Patients were randomly assigned to two groups: the ceftriaxone group (R-group, n=95) and sulperazon group (S-group, n=95). Before choledochostomy, both groups received one intravenous dose of the corresponding antibiotics: and 2 g ceftriaxnoe for the R-group, 2 g sulperazon, containing 1 g cefoperazone and 1 g sulbactam, for the S-group. After the operation, the patients in the R-group received ceftriaxone 2 g i.v. q.d.; the patients in the S-group received sulperazon 2 g i.v. b.i.d.. In addition, all patients in both groups received metronidazole 0.5 g daily before and after the operation. The efficacy was evaluated by efficiency in controlling infection and the persisting days of symptoms due to infection, fever and leukocytosis; the persisting days was compared using the life table method to calculate the "cumulative probability of persistence of symptoms (CPPS)". The two groups were also compared in regards to their biliary bacterial clearance rates and the costs directly attributable to the antibiotics. RESULTS: The efficiency in controlling infection was 98.9% (94/95) in both groups. However, the CPPS of the R-group decreased more rapidly than that of the S-group, Log-Rankchi2=6.7901, P=0.0092. Biliary bacterial clearance rate on post-operative day 3 was 72.0% (36/50) for the R-group, 41.3% (19/46) for the S-group, P=0.0037. Cost directly attributable to the antibiotics were (1788.29 +/- 518.46) yuan (RMB) for the R-group, and (3768.74 +/- 820.55) yuan for the S-group, F=395.51, P=0.0000. CONCLUSION: Both ceftriaxone and sulperazon are effective in treating acute suppurative cholangitis when used before and after choledochostomy. Ceftriaxone is superior in expediting symptom relief and bacterial clearance from bile, and is more cost-effective.

[Evaluation oxygen free radicals related index before liver transplantation to forejudge prognosis].

OBJECTIVE: To research the relationship of oxygen free radicals related index before liver transplantation with prognosis. METHODS: Lipid peroxide (LPO), total antioxidant capacity (TAC), nitric oxide (NO) and total bilirubin (T-BIL) in blood from 18 patients were measured before liver transplantation, and the relationship with prognosis was analyzed. RESULTS: The blood LPO of death group was (17.13+/-4.16) micromol/L, it was obviously higher than that of survival group (7.97+/-3.52) micromol/L (P<0.05). The blood TAC of survival group was (38.05+/-19.13) kU/L, it was higher than that of death group (32.54+/-3.07) kU/L, but there was no obvious difference(P>0.05). There was no obvious difference between the blood NO of death group was (50.80+/-14.80) micromol/L, and survive group was (150.46+/-19.54) micromol/L (P>0.05). The blood T-BIL of death group was (425.98+/-214.18) micromol/L, it was obviously higher than that of survival group (172.10+/-144.32) micromol/L (P<0.05). So the blood LPO and TAC were chosen as the index to forejudge prognosis, and an equation was established to forecast if the patient would be death or survive: Y(1)=0.329 0 X(1)+0.099 8 X(2)-3.9040, Y(2)=1.352 0 X(1)-0.0500 X(2)-11.4640, X(1) represented serum LPO, X(2) represented serum TAC. 100.0 percent accuracy was forecasted in the survival group by the equation, 83.3 percent accuracy was in the death group. The overall patients were forejudged 94.4 percent accurately. CONCLUSION: Measuring LPO and TAC in blood maybe forejudging prognosis properly and can be used as routine examination before liver transplantation. The equation is preferable to forejudging prognosis, it can be used to choose from high risk patients to improve survival rate of the patients after operation. Therefore, it is valuable in clinical practise.
