Two patients died of tumor recurrence and metastasis witnin one year after operation, and the rest had disease-free survival until the end of follow-up.ConclusionFrom preliminary results of limited cases in this study, π-shaped esophagojejunal anastomosis in TLTG is a technically safe and feasible surgical procedure in treatment of gastric cancer.
Objective To study anatomy of mortis corona vascular and analyze its characteristics and clinical significances in laparoscopic total extraperitoneal hernia repair (TEP). Method The clinical data of 45 patients with inguinal hernia underwent laparoscopic TEP from July 2013 to October 2015 in the Fourth People’s Hospital of Zigong City were collected. Results ① There were 45 patients with inguinal hernia a total of 52 bilateral inguinal hernias (15 direct hernias, 37 oblique hernias). The total appear rate of corona mortis vascular was 61.5% (32/52). The appear rate of corona mortis artery was significantly higher than that of the corona mortis vein〔46.2% (24/52)versus 34.6% (18/52),P<0.05〕, the diameter of the corona mortis artery was significantly smaller than that of the corona mortis vein〔(3.2±0.3) mmversus (3.4±0.4) mm,t=2.231,P<0.05〕. ② The appear rates of corona mortis artery and vein in the male patients were significantly higher than those of the female patients (P<0.05). Compared with the female patients, the age of onset was older (P<0.05), thickness of abdominal wall was thinner (P<0.05), diameter of corona mortis vascular was bigger (P<0.05) in the male patients. ③ The total appear rate of corona mortis vascular in the patients with direct hernia was significantly lower than that of the patients with oblique hernia (P<0.05). The age of onset of the patients with direct hernia was significantly older than that of the patients with oblique hernia (P<0.05). Conclusions There is a higher appear rate of corona mortis vascular in patients with oblique hernia, which in male patients is higher as compared with female patients. Age of onset of male patient with inguinal hernia is older than that of female patient with inguinal hernia. It suggests that appear of corona mortis vascular might be associated with degeneration of abdominal wall. It has a certain role for localization and avoidance of corona mortis vascular in TEP.
Objective To investigate feasibility and clinical efficacy of exploration and stone removal through choledochoscope via hepatic cross-section during laparoscopic left lateral hepatectomy for hepatolithiasis. Methods The patients who had left extrahepatic bile duct stones with choledocholithiasis from January 2012 to December 2016 were retrospectively collected. Among these patients, 29 cases underwent an exploration and stone removal through choledochoscope via hepatic cross-section during laparoscopic left lateral hepatectomy (observation group) and 26 cases underwent an exploration and stone removal through choledochoscope via incision of common bile duct during laparoscopic left lateral hepatectomy (control group). The operative time, intraoperative blood loss, postoperative hospital stay, postoperative nutritional, and complications rate were compared between these two groups. Results The operations were performed successfully and no perioperative death happened in both groups. There were no significant differences in the operative time and intraoperative blood loss between the two groups (P>0.05). Moreover, the postoperative hospital stay of the observation group was significantly shorter than that of the control group (P<0.05). In addition, there were no significant differences in the complications of the bile leakage, subphrenic infection, and biliary residual stones between the two groups (P>0.05). Also, the levels of prealbumin and the lymphocytes in the observation group were significantly higher than those in the control group on the 3rd and 6th day after the operation (P<0.05). Conclusions Preliminary results of limited cases in this study show that exploration and removal of stones through choledochoscope via hepatic cross-section during laparoscopic left lateral hepatectomy for hepatolithiasis is relatively safe and reliable, its procedure is simplified, could avoid relevant complications due to biliary incision and T tube drainage.
ObjectiveTo discuss application of " counter clockwise resection” in total laparoscopic pan-creaticoduodenectomy (TLPD) and summarize it’s preliminary experiences.MethodThe clinical data of consecutive 8 patients underwent TLPD in the Department of Pancreatic Surgery, Affiliated Shengjing Hospital of China Medical University from July 2016 to January 2017 were analyzed retrospectively.ResultsThere were 3 males and 5 females in these 8 patients. The age was (64.13±15.01) years. The results of postoperative pathology included 1 duodenal cancer, 2 distal biliary tract cancers, 4 pancreatic head cancers, and 1 solid pseudopapillary tumor of pancreatic head. All the 8 patients were performed with TLPD successfully, and the time of the operation was (527.50±69.44) min, the resection time of the specimen was (241.25±38.71) min, and the blood loss was (368.75±162.43) mL, the postoperative hospitalization stay was (18.67±4.00) d. There were no postoperative bleeding, perioperative death, and delayed gastric emptying．Four patients suffered from the pancreatic fistula including 3 cases of grade A and 1 case of grade B pancreatic fistulas, and 1 case suffered from the intra-abdominal infection, who were cured after the conservative treatment. All the patients were following-up, and there was no abnormality.ConclusionPreliminary results of limited cases in this study show that " counter clockwise resection” might be a safe, effective, and easy method of TLPD, but further research is need to study.
ObjectiveTo compare the short-term clinical outcomes of laparoscopic pancreaticoduodenectomy (LPD) with open pancreatoduodenectomy (OPD).MethodsClinical data of 29 patients receiving LPD and 27 patients receiving OPD in the department of hepatobiliary surgery of the Second Affiliated Hospital of Chongqing Medical University from March 2016 to December 2018 were collected. Note that both LPD and OPD were performed by the same chief surgeon. Effectiveness and safety of LPD were compared with those of OPD.ResultsThere was no significant difference in age, sex, body mass index, total bilirubin level, direct bilirubin level, preoperative morbidities, focus size, TNM stage and ASA grade between the LPD group and the OPD group (P>0.05). The operative time of the LPD group was significantly longer than that of the OPD group ［(482±86 ) min vs. (349±73) min, P<0.01］. Patients in the LPD group had shorter postoperative anal exhaust time than that in the OPD group ［(3.3±0.8) d vs. (5.3±1.0) d , P<0.05］. There was no significant difference in the length of hospital stay after operation, blood loss in operation, transfusion, second operation, death and postoperative complications between the LPD group and the OPD group (P>0.05).ConclusionsThe preliminary results of this study suggest that compared with OPD, LPD can shorten the postoperative anal exhaust time but not increase the incidence of postoperative complications and blood loss in operation. Nevertheless, this conclusion is needed to be validated by clinical studies with large sample size.
Tumors located in the middle lobe of liver were usually subjected to extended hemihepatectomy due to its special anatomical location and high surgical difficulty. However, the incidence of postoperative liver failure and mortality increased accordingly for patients with liver cirrhosis and poor liver function because more liver parenchyma was resected. Therefore, some researchers proposed to use central hepatectomy to treat. However, due to the higher-level technology and the higher risk, it had not been carried out routinely following decades. Later, with the rapid development of laparoscopic technology in the liver surgery and its advantages such as small trauma, rapid postoperative recovery, and the same efficacy as open liver surgery, the reports on laparoscopic central hepatectomy (LCH) at home and abroad had been increasing year by year. Especially, with the standardization of LCH, the development of LCH will be promoted. LCH might become the mainstream of surgical treatment of middle liver tumors in the future.
ObjectiveTo compare efficacy of laparoscopic or open hepatectomy in benign liver tumors patients with different difficult operations. MethodsAccording to the inclusion and exclusion criteria, the patients with benign liver tumors who underwent hepatectomy in the Affiliated Hospital of Xuzhou Medical University from September 2014 to March 2021 were collected. The enrolled patients were assigned into low, medium, and high difficulties by the Hasegawa liver resection surgical difficulty score model, then the patients were matched by propensity score matching. The liver function and inflammatory indexes, intraoperative bleeding, operative time, total hospital stay, postoperative complications, and hospitalization expenses of patients with benign liver tumors after laparoscopic (laparoscope group) or open (open group) hepatectomy were compared. ResultsA total of 209 patients who met the inclusion and exclusion criteria were enrolled in this study. According to the Hasegawa criteria, there were 59, 89, and 61 patients with low, medium, and high difficulties respectively. After 1∶1 propensity score matching, 18, 34, and 14 patients in the laparoscope group and open group were matched respectively. There were no statistic differences in the baseline data between the laparoscope group and open group (P>0.05). ① For the patients with low and medium difficulties, compared with the open group, the different values of alanine aminotransferase, aspartate aminotransferase, white blood cell count, and neutrophil percentage were lower (P<0.05), the intraoperative bleeding and total hospital stay were less or shorter (P<0.05), and the albumin were higher (P<0.05) in the laparoscope group. There were no statistic differences in these indexes among the patients with high difficulty (P>0.05). ② Compared with the open group, the operative time of the laparoscope group was shorter in the patients with low difficulty (P<0.05) and longer in the patients with high difficulty (P<0.05), and there was no statistic difference in patients with medium difficulty (P>0.05). ③ The postoperative complications had no statistic differences between the two groups for the patients with low and high difficulties (P>0.05), while which in the laparoscope group were lower than in the open group for the patients with medium difficulty (P<0.05). ④ The hospitalization expenses of the laparoscope group was higher than the open group for the patients with high difficulty (P<0.05), while which had no statistic differences between the two groups for the patients with low and medium difficulties (P>0.05). ⑤ The total hospital stay of the laparoscope group was shorter than the open group (P<0.05) no matter which difficult operation.ConclusionsAccording to results of this study, laparoscopic hepatectomy has more obvious advantages as compared with open hepatectomy for patients with low or medium difficulty, which could greatly shorten hospital stay and accelerate rehabilitation of patients. Even for patients with high difficulty, laparoscopic hepatectomy still shows an advantage of shortening hospital stay.
ObjectiveTo investigate the advantage of superior mesenteric artery approach in laparoscopic pancreaticoduodenectomy (LPD) combined with superior mesenteric vein (SMV)-portal vein (PV) resection and reconstruction. MethodThe operation process of a pancreatic head cancer patient with SMV-PV invasion admitted to the Second Affiliated Hospital of Chongqing Medical University in April 2022 was summarized. ResultsThe resection and reconstruction of SMV-PV during the LPD through the right posterior approach and anterior approach of superior mesenteric artery was completed successfully. The operation time was 7.5 h, the intraoperative blood loss was 200 mL, and the SMV-PV resection and reconstruction time was 20 min. The patient was discharged with a better health condition on the 9th day after operation. ConclusionFrom the operation process of this patient, the arterial priority approache is a safe and effective approach in the resection and reconstruction of SMV-PV during the LPD.
ObjectiveTo explore technical essentials and safety of laparoscopic cholecystectomy (LC) guided by gallbladder ampulla localization on an imaginary clock for cholecystitis.MethodsA retrospective study of 8 707 continuous patients with mild cholecystitis who underwent LC from July 1998 to February 2018 at a single institution was conducted. Among them, 3 168 patients were treated by the traditional LC from July 1998 to February 2007 (a traditional LC group), 5 539 patients were treated by the LC with the guidance of the gallbladder ampulla localization on an imaginary clock from March 2007 to February 2018 (a gallbladder ampulla localization group). The conversion to open surgery, bile duct injury, return to the operating room due to postoperative massive abdominal bleeding, bile leakage without bile duct injury, operative time, intraoperative blood loss, and postoperative hospital stays were compared between the traditional LC group and the gallbladder ampulla localization group.ResultsThere were no significant differences in the gender, age, course of disease, and type of cholecystitis between these two groups (P>0.050). The rates of conversion to open surgery, bile duct injury, return to the operating room due to postoperative massive abdominal bleeding, bile leakage without bile duct injury and the operative time, intraoperative blood loss and postoperative hospital stays in the traditional LC group were 3.00% (95/3 168), 0.13% (4/3 168), 0.09% (3/3 168), 0.03% (1/3 168), (43.6±12.6) min, (18.7±3.3) mL, (3.6±2.7) d, respectively, which in the gallbladder ampulla localization group were 0 (0/5 539), 0 (0/5 539), 0 (0/5 539), 0 (0/5 539), (32.2±10.5) min, (12.4±3.5) mL, (3.5±2.8) d, respectively. The differences of conversion to open surgery, bile duct injury, return to the operating room due to postoperative massive abdominal bleeding rates, and the operative time and intraoperative blood loss were statistically significant between these two groups (P<0.050). The differences of the bile leakage without bile duct injury rate and postoperative hospital stays were not statistically significant between the two groups (P>0.050).ConclusionThis study shows that gallbladder ampulla localization on an imaginary clock is useful for ductal identification so as to reduce bile duct injury and improve safety of LC in case of no conversion to open surgery.
Laparoscopic anatomical hepatectomy had developed considerably in recent years, but some complex sites of anatomical hepatectomy, such as anatomical resection of the right posterior lobe of the liver, still presented some technical difficulties. Combining the specific perspective of laparoscope and the particular anatomical structure of the right posterior lobe of the liver, we had proposed a strategy of anatomical right posterior lobe resection via cranial-dorsal approach. The right posterior lobe resection plane was defined by point (right hepatic vein root)—by line (ischemic line/right hepatic vein)—by plane (hepatic surface ischemic line and right hepatic vein composition) to achieve precise anatomical resection of the right posterior lobe of the liver, and could reduce intraoperative complications and comply with the principle of tumour-free. Thus, a strategy of anatomical right posterior lobe resection via cranial-dorsal approach might provide a feasible and effective option for right posterior lobectomy of the liver.
