Chinese Journal of Digestive Surgery.2011;10(1):33-35. doi:10.3760/cma.j.issn.1673-9752.2011.01.009

Objective To investigate the value of Habib 4X in hepatic resection. Methods The clinical outcome of 21 patients with liver disease who received liver resection at the Tianjin Third Central Hospital from November 2009 to April 2010 were retrospectively evaluated. All the operations were carried out by using Habib 4X. Results All patients received hepatectomy, including right hepatectomy in three patients, left hepatectomy in one patient, multiple segmentectomy in nine patients, single segmentectomy in seven patients and partial liver resection in one patient. All tumors were reseeted completely. The mean operation time was (50±25) minutes and the mean blood loss was(129±117)ml. No patient was transferred to ICU. Three patients were complicated with bile leakage, one with lymphatic leakage and four with pleural effusion, and they were cured by non-surgical treatment. There were no patients with postoperative hemorrhage, incision infection or hepatic failure. No mortality was observed. The mean postoperative hospital stay was(19±14)days. Conclusions Radiofrequency energy was applied along the margins of the tumor to create zones of necrosis before resection with a scalpel, offering hepatobiliary surgeons an additional method for performing liver resections with minimal blood loss, low morbidity and mortality rates. As for malignant tumors, minor or major liver resection assisted by Habib 4X is safe, and it can reduce the chance of positive incisal margin.

Objective To investigate the guiding significance of medical image three-dimensional visualization system (MI-3DVS) in precise hepatectomy. Methods The clinical data of 45 patients with hepatic neoplasms who were admitted to the Zhujiang Hospital from June 2008 to September 2010 were prospectively analyzed. The preoperative image data of the liver were three-dimensionally reconstructed by MI-3DVS. According to the distribution of the intrahepatic portal veins and hepatic veins, the liver was divided into different sections,and then tumors can be located within these hepatic segments. The volume percentage of residual liver and volume of liver resected were detected. Evaluation of surgical resectability and surgery simulation were done before operation. Results According to the distribution of the intrahepatic portal veins and hepatic veins, all patients were divided into seven types: 21 patients were with normal type which was the same as Couinaud type, six with nondivided type, 11 with non-divided right liver type, four with non-divided left liver type, one with right hepatic vein type, one with double middle hepatic vein type and one with right posterior vein type. Thirty-nine patients received open hepatectomy, and the volume percentage of the residual liver was 74% ± 17%. Postoperative pathological examination confirmed that all the 39 patients were with hepatocellular carcinoma. Six patients received transcatheter arterial chemoembolization. No severe complications such as acute hepatic failure, bleeding, bile leakage were detected. All patients were followed up for six months, and they survived with or without tumor. Conclusion MI-3DVS has guiding significance in preoperative assessment and perioperative guidance for precise hepatectomy.

Chinese Journal of Digestive Surgery.2011;10(1):26-28. doi:10.3760/cma.j.issn.1673-9752.2011.01.007

Objective To evaluate precise hepatectomy for liver metastases of colorectal cancer. Methods The clinical data of 85 patients with liver metastases of colorectal cancer who were admitted to the Cancer Hospital of Tianjin Medical University from October 2006 to October 2009 were retrospectively analyzed. Forty-two patients received precise hepatectomy(precise group) and 43 received routine hepatectomy (routine group). Evaluation of the hepatic and renal functions and detection of the tumors' condition were done before carrying out anatomical liver resection for patients in the routine group. Hepatic functional reserve of patients in the precise group was detected by indocyanine green excretion test. Hepatic artery, hepatic vein and portal vein were three-dimensionally reconstructed according to the data of computed tomography. The liver volume and residual liver volume of the patients were calculated. Hepatic resection was guided by intra-operative ultrasound in the precise group. Periand postoperative conditions and the results of follow-up of patients in the two groups were compared. All data were analyzed using the t test or chi-square test. Results No perioperative mortality was observed in the two groups.Time of hepatic blood flow occlusion and blood loss were (35±25)minutes and (685 ± 524) ml in the routine group, and (64±39) minutes and (486±360) ml in the precise group, respectively, with a significant difference between the two groups(t=4.116,-2.033, P＜0.05). The volumes of blood transfusion of the routine group and the precise group were (228±398) ml and (160±330)ml, respectively, with no significant difference between the two groups (t=-0.861, P＞0.05). The postoperaive levels of alanine transaminase at day 1 and day 7 were (672±284)U/L and (332±161)U/L in the routine group, and (344±158)U/L and (125 ±93) U/L in the precise group, respectively, with a significant difference between the two groups (t=-6.541,-7.232,P＜0.05). The length of hospital stay and postoperative mobidity were (18±10)days and 26% (11/43) in the routine group, and (12±6)days and 7%(3/42) in the precise group, respectively, with a significant difference between the two groups (t=- 3.915, x2=5.251, P＜0.05). The 1-year tumor recurrence rate and 1-year survival rate were 37% (16/43) and 88% (38/43) in the routine group, and 21% (9/42) and 93% (39/42) in the precise group, with no significant difference between the two groups (x2= 0.110, 0. 501, P＞0.05). Conclusion Precise hepatectomy is superior to routine hepatectomy in aspect of minimal trauma, quick recovery, efficacy and safety.

Challenges and thoughts on precise hepatectomy

Hongchi JIANG ; Lianxin LIU

Chinese Journal of Digestive Surgery.2011;10(1):4-5. doi:10.3760/cma.j.issn.1673-9752.2011.01.002

Precise hepatectomy is the application of minimally invasive concept in hepatic surgery. There are big challenges for surgeons to choose the proper approaches to achieve the aim of precise hepatectomy. How to choose therapeutic strategy, chemotherapy, radiotherapy, liver transplantation or radiofrequency ablation? How to choose the operation type, laparoscopic surgery, transabdominal surgery or Da Vinci robot-assisted surgery? How to choose the surgical instruments during hepatectomy? Although answers for these questions are various, the principle is unchangeable, which is providing minimal injury, less blood loss, fast recovery, little expense and good prognosis. The concept of precise hepatectomy includes precise judgment of liver function and careful preparation before operation, and also the elaborate nursing and multi-disciplinary cooperation during operation, as well as the fast track surgery after operation. Precise hepatectomy requires surgeons take the safety and effectiveness of the operations into account, and the conditions of hospitals, the skills and experiences of the surgeons should also be evaluated before operation. Finally, the economic condition of the patients should be considered and proper application of advanced equipments should be emphasized.

Chinese Journal of Digestive Surgery.2011;10(1):64-67. doi:10.3760/cma.j.issn.1673-9752.2011.01.019

Objective To explore a new method for one-stage repair of the intestinal leakage based on the principle of magnetic compression anastomosis. Methods Twenty-four dogs were randomly divided into experimental group (n = 12) and control group (n = 12) according to random number table. The model of upper and multiple intestinal leakages was established by making transverse incisions of 1 cm in length on the jejunum wall about 50 cm and 100 cm away from the Treitz ligament. Forty-eight hours later, two NdFeB magnetic rings with the magnetic flux of 2500 G were put into the intestine from the leak sites. The leak sites were pressed between the two rings. The ventages in the control group were sutured. The condition of the dogs was observed after the repair of the leakage. The excreting time was recorded, and the leakage pressures of the anastomotic stoma were detected.The positions of the magnetic rings in the experimental group were detected by X ray. Tissues of the anastomotic stoma were processed by hematoxylin eosin and Masson staining. All data were analyzed using the two-sample t test. Results Severe abdominal infection occurred 48 hours after the establishment of the model. All the intestinal leakages in the experimental group were successfully repaired and the dogs survived for a long time. The magnetic rings were excreted six or seven days after the repair. Eight dogs of the control group survived. The leakage pressure of the anastomotic stoma seven days after the repair was (134 ±23)mm Hg (1 mm Hg =0. 133 kPa) in the experimental group and (91 ± 18)mm Hg in the control group, respectively, with a significant difference between the two groups (t = 3.225, P ＜ 0.05). The leakage pressure of the anastomotic stoma 14 days after the repair was (281 ±7)mm Hg in the experimental group and (271 ±21) mm Hg in the control group, respectively, with no significant difference between the two groups (t =0. 988, P ＞ 0.05). Histological observation showed that after the magnetic compression anastomosis, the intestinal muscle and mucosa recovered well, inflammatory reaction was slight and less collagen fiber and scar was formed. Conclusions Application of magnetic ring with the magnetic flux of 2500 G in one-stage repair of the intestinal leakage in the state of severe abdominal infection is safe and reliable.

Chinese Journal of Digestive Surgery.2011;10(1):60-63. doi:10.3760/cma.j.issn.1673-9752.2011.01.017

Objective To assess the value of indocyanine green excretion test in predicting hepatic failure after hepatectomy. Methods The retention rate of indocyanine green at 15 minutes (ICG R15), effective hepatic blood flow (EHBF) and clinical and biochemical parameters of 128 patients who received hepatectomy at the Affiliated Provincial Hospital of Anhui Medical University from June 2007 to June 2008 were detected by pulse dye densitometry. All patients were divided into non-hepatic failure group (n = 110) and hepatic failure group (n =18). ICG R15, EHBF, Child's score, histology activity index (HAI) score, clinical and biochemical parameters and other indexes were analyzed to predict hepatic failure by the t test, chi-square test, linear regression analysis or regression model. The relationship between positive predictive indexes and HAI score was studied. Results Eighteen patients suffered from hepatic failure after operation. ICG R15, Child's score, HAI score of patients without hepatic failure were 9% ±4%, 5.6 ±0.7, 3.8 ±0.5, which were significantly lower than 15% ±6%,6.1 ± 0. 8, 5.0 ± 0. 8 of patients with hepatic failure (t = 11. 121,2. 356, 3. 915, P ＜ 0.05). EHBF of patients without hepatic failure was (1.2 ±0.2) L/min, which was significantly higher than (1.0 ±0.2) L/min of patients with hepatic failure (t = 2. 802, P ＜ 0. 05). In a logistic regression model, age ≥ 65 years, ICG R15 ≥ 14% and EHBF ＜ 1.0 L/min were risk factors of postoperative hepatic failure (x2 = 4. 758, 9.709, 5. 362, P ＜ 0.05).ICG R15 was negatively correlated with EHBF (r =-0. 527, P ＜0.05). HAI score was positively correlated with ICG R15 (r =0. 638, P ＜0.05), while it was negatively correlated with EHBF (r =-0. 445, P ＜0. 05).Conclusions ICG R15 and EHBF are good predictive indicators for hepatic failure after hepatectomy. Patients with ICG R15≥14% and EHBF ＜ 1.0 L/min are prone to have postoperative hepatic failure.

Objective To investigate the characteristics and treatment of the complications of Crohn's disease. Methods The clinical data of 202 patients with Crohn's disease and relevant complications who were admitted to the Nanjing General Hospital of Nanjing Military Command from January 2000 to December 2007 were retrospectively analyzed. The main complications included intestinal obstruction, fistula, acute perforation,abscess, abdominal mass and et al. Results Of the 202 patients, 116 had more than two complications. Intestinal obstruction (72 patients) was the most common complication among the initial complications, and followed by fistula (31 patients), acute perforation (23 patients), abscess (22 patients), abdominal mass (22 patients),anal complications (21 patients) and gastrointestinal bleeding (11 patients). Fistula was mostly observed in patients with secondary complications during the early stage (≤three months), while obstruction (24 patients),fistula (22 patients) and obscess (11 patients) were prevalent during the mid-late stage (＞ three months). Of the 202 patients with primary complications, 170 received surgical treatment and 32 received non-surgical treatment. Of the 116 patients with secondary complications, 96 received surgical treatment and 20 received non-surgical treatment. A total of 127 patients were cured by surgical treatment, the condition of 33 patients was improved and six patients died. The condition of patients received non-surgical treatment was improved, and no patient died.Conclusions The incidence of complications of Crohn's disease is increasing steadily. Intestinal obstruction is the most common complication, and then followed by fistula. Surgery is important in the treatment of the complications of Crohn's disease.

Chinese Journal of Digestive Surgery.2011;10(1):53-56. doi:10.3760/cma.j.issn.1673-9752.2011.01.015

Objective To investigate the clinicopathological features of multiple primary colorectal carcinoma. Methods The clinical data of 30 patients with multiple primary colorectal carcinoma and 580 patients with single colorectal carcinoma who were admitted to the Peking University People's Hospital from January 2001 to March 2008 were retrospectively analyzed. There were 16 patients with multiple synchronous carcinoma and 14with multiple metachronous carcinoma. The survival of the patients was analyzed using Kaplan-Meier method and the survival rates were compared using Log-rank test. All data were analyzed using the chi-square test. Results The onset age of multiple metachronous primary carcinoma was younger than that of multiple synchronous carcinoma and single colorectal carcinoma, while the onset age of multiple metachronous secondary carcinoma was close to that of multiple synchronous carcinoma and single colorectal carcinoma. Most of the synchronous carcinoma located at the left colon; while most of the metachronous primary carcinoma located at the rectum and sigmoid colon, and most of the metachronous secondary carcinoma located at the ascending colon. Patients with multiple synchronous carcinoma or multiple metachronous primary carcinoma received radical resection. Of the 14 patients with multiple metachronous carcinoma, 9 received radical resection for secondary focus. Except for three patients with multiple synchronous carcinoma and two patients with multiple metachronous carcinoma, all patients received postoperative chemotherapy with FCF, FOLFOX or XELOX regimen. Of the 580 patients with single colorectal carcinoma, 512 received radical resection, 68 received palliative operation, and 519 received postoperative chemotherapy. The cumulative survival rate of patients with multiple metachronous primary carcinoma was significantly higher than that of single colorectal carcinoma (x2 = 17. 289, P ＜ 0. 05). There was no significant difference in the cumulative survival rate between patients with single colorectal carcinoma and those with multiple metachronous secondary carcinoma or multiple synchronous carcinoma (x2 = 1.731, 0. 800, P ＞ 0. 05). Conclusion The prognosis of patients with colorectal multiple metachronous carcinoma is better than those with single colorectal carcinoma, and the prognosis of colorectal synchronous carcinoma is similar to those with single colorectal carcinoma.

Chinese Journal of Digestive Surgery.2011;10(1):40-43. doi:10.3760/cma.j.issn.1673-9752.2011.01.011

Objective To evaluate the efficacy of living donor liver transplantation in the treatment of infants with end-stage liver diseases. Methods The clinical data of 33 infants who received living donor liver transplantation at the Renji Hospital of Shanghai Jiaotong University from October 2006 to September 2009 were retrospectively analyzed. The median age of the infants was 10.9 months, and the mean body weight was 8.2 kg.All of the grafts were left lateral lobes. Tacrolimus (or cyclosporine A) + steroid or tacrolimus (or cyclosporine A)+ steroid + mycophenolate mofeti] were applied to the infants to suppress the immune reaction. Operative techniques, perioperative management and results of follow-up were analyzed. Results The mean operation time,blood loss and blood transfusion of the donors were (384±108)minutes, (183±35) ml and O, and the three indexes of the recipients were (500± 103) minutes, (296±163) ml and (292 ± 159) ml , respectively. The cold preservation time of the grafts was (64 ±23)minutes, the mean weight of the grafts was (249 ±52)g, and the mean graft to recipient weight ratio was 2.1% ± 0.4%. All donors recovered smoothly and no complication occurred. Of the recipients, three were complicated with hepatic artery thrombosis, two with portal vein thrombosis,nine with biliary complications, 11 with infection, two with acute rejection and five infants died perioperatively.The one-year cumulative survival rate of the infants was 85% (28/33). Conclusions Infants with end-stage liver diseases could be treated by living donor liver transplantation. The development of surgical techniques and perioperative managements improves the success rate of operation and the long-term survival rate.
