ObjectiveTo summarize the diagnosis and treatment process of a patient who underwent laparoscopic local excision of duodenal papillary tumor, and to explore the safety and feasibility of this surgery. MethodThe clinicopathologic characteristics and surgical procedure of the patient with duodenal papillary neuroendocrine tumor admitted to the West China Hospital of Sichuan University in June 2021 were retrospectively analyzed. ResultsThe patient underwent the laparoscopic local excision of duodenal papillary tumor + in situ cholangiojejunostomy and pancreaticojejunostomy. The operation lasted about 3 hours, the blood loss was about 20 mL, and the patient exhausted on the 3rd day after the operation. On the 7th postoperative day, the gastric tube was pulled out and oral feeding was started. On the 8th day, the plasma drainage tube was pulled out and the patient was discharged smoothly. There was no duodenal fistula, bleeding, wound infection, and other complications. After 6 months of follow-up, the general condition of this patient was good, and no tumor recurrence or metastasis was found. ConclusionLaparoscopic local excision is an appropriate option for benign or low-grade malignancies involving the duodenal papillary tumor.
Objective To explore the related factors of postoperative pulmonary infection (PPI) in patients undergoing laparoscopic colorectal cancer surgery, and analyze the perioperative management strategy of pulmonary infection combined with the concept of enhanced recovery after surgery (ERAS). Methods Total of 687 patients who underwent laparoscopic colorectal cancer surgery in the colorectal cancer professional treatment group of Gastrointestinal Surgery Center of West China Hospital of Sichuan University from January 2017 to May 2019 were retrospectively included. According to the occurrence of PPI, all the included cases were divided into infection group (n=97) and non-infection group (n=590). The related factors and prevention strategies of PPI were analyzed. Results The rate of PPI among patients underwent laparoscopic resection in our study was 14.1% (97/687). Compared with the non-infection group, the proportions of patients with preoperative complications other than cardiopulmonary, receiving preoperative neoadjuvant radiotherapy and/or chemotherapy, preoperative Eastern Cooperative Oncology Group (ECOG) score 1–2, preoperative Nutrition Risk Screening 2002 (NRS2002) score 1–3, tumor located in the left colon and rectum, combined organ resection, operative time >3 h and postoperative TNM stage Ⅱ patients in the infection group were higher (P<0.05). However, the proportions of patients who used intraoperative lung protective ventilation strategy and incision infiltration anesthesia in the infection group were lower than those in the non-infection group (P<0.05). In the infection group, the proportions of patients who received regular sputum excretion, atomization therapy, balloon blowing/breathing training, stomatology nursing after operation and postoperative analgesia were all significantly lower than those of the non-infection group (P<0.05), whereas the proportions of patients receiving antibiotics and intravenous nutrition after operation were significantly higher than those in the non-infection group (P<0.05). Logistic regression analysis showed that low preoperative NRS2002 score, intraoperative protective ventilation strategy, postoperative respiratory training, and postoperative regular sputum excretion were the protective factors of PPI, while preoperative cardiopulmonary complications, preoperative neoadjuvant chemotherapy, tumor located in the left colon and rectum, late TNM staging and postoperative antibiotics were risk factors for pulmonary infection.Conclusions Preoperative cardiopulmonary complications, preoperative neoadjuvant chemotherapy, tumor location in the left colon and rectum, late TNM staging and postoperative antibiotics are risk factors for pulmonary infection in patients with laparoscopic colorectal cancer. Preoperative good nutritional status, intraoperative protective ventilation strategy, postoperative respiratory training and regular sputum excretion may reduce the incidence of PPI to a certain extent.
Objective To compare efficacy of laparoscopic and open duodenal circular drainage operation for superior mesenteric artery compressing syndrome (SMACS). Methods From December 2012 to December 2015, the clinical data of 23 cases of laparoscopic duodenal circular drainage operation (laparoscope group) and 28 cases of open duodenal circular drainage operation (open group) were analyzed. The operation time, intraoperative bleeding, postoperative ambulation time, postoperative analgesics usage, postoperative the first exhaust time, postoperative the first feeding time, postoperative hospitalization time and postoperative incidence of complications were compared. The patients were followed up to confirm the effect after the operation. Results There were no differences of the age, sex, and body weight index between the laparoscope group and the open group (P>0.05). The operation time had no significant difference between these two groups (P>0.05). Compared with the open group, the intraoperative bleeding was less (P<0.05), the postoperative ambulation time, postoperative the first exhaust time, postoperative the first feeding time, postoperative hospitalization time were shorter (P<0.05), the rates of postoperative analgesics usage, incision infection, pulmonary infection, and intestinal obstruction were lower (P<0.05) in the laparoscope group. The rates of anastomotic leakage and anastomotic bleeding, and total postoperative complications rate had no significant differences between these two groups (P>0.05). All the patients were followed up for 8–36 months. The clinical symptoms disappeared and the body weight increased to normal level in the two groups. Conclusions Preliminary results of in this study show that laparoscopic duodenal circular drainage operation in treatment of SMACS has some advantages such as less trauma, faster recovery, fewer complications and shorter hospitalization time. Laparoscopy will be an ideal choice for treatment of SMACS.
ObjectiveTo summarize the application status and prospect of laparoscopic pancreaticoduodenectomy (LPD).MethodThe relevant literatures about studies of LPD at home and abroad were reviewed.ResultsLPD was a difficult operation, mainly suitable for pancreatic head and periampullary benign and malignant tumors. With the development of laparoscopic techniques in recent years, LPD combined the superior mesenteric vein and portal vein resection and reconstruction, or combined multi-visceral resection was feasible, but the survival benefit of LPD with arterial resection and reconstruction and extended lymph node dissection remained to be discussed. At present, there was no clear requirement on the way to reconstruct the pancreatic fluid outflow tract, but the pancreaticojejunostomy for digestive tract reconstruction was chose by the most surgeons. The most studies had confirmed that LPD was minimally invasive and had a short-term prognosis that was not inferior to that of open pancreaticoduodenectomy. However, the results of large sample analysis about long-term survival rate and oncology results were lacking, so it was difficult to judge the advantages and disadvantages of long-term prognosis of the two methods.ConclusionsLPD is a safe, feasible, reasonable, and effective surgical method. With improvement of laparoscopic technology, LPD is expected to become a standard operation method for treatment of pancreatic head cancer and periampullary carcinoma, and oncology benefits of LPD will be further confirmed in future by large-sample clinical randomized control trials and studies of long-term prognosis follow-up.
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.
Objective To assess safety and feasibility of laparoscopic gastrectomy in the elderly with gastric cancer. Methods From January 2010 to September 2014, 146 elderly (age ≥65 years old) patients with gastric cancer underwent radical operations in the Department of General Surgery, Guangdong Academy of Medical Sciences and Guangdong General Hospital were collected, then were divided into a laparoscopy-assisted radical gastrectomy (LAG group, n=40) and an open radical gastrectomy (OG group, n=106) according to the operative mode. The differences of intraoperative and postoperative situation, and the postoperative complications were analyzed between the LAG group and the OG group. Results ① The age, gender, body mass index, albumin, ASA grade, tumor location, differentiation degree, TNM stage, radical gastrectomy, and digestive tract anastomosis had no significant differences between the LAG group and the OG group (P>0.05). ② None of the patients died during the operative period and there was no significant difference in the mean number of retrieved lymph nodes between these two groups (P>0.05). In the aspects of the intraoperative blood loss, the first flatus time or the first feeding time, and the postoperative hospitalization stay in the LAG group were significantly less than those in the OG group (P<0.05). For the operative time, the OG group showed a distinctive advantage with a significantdifference than the LAG group (P<0.05). ③ The rate of postoperative complication in the LAG group and OG group was 10.0% (4/40) and 15.1% (16/106) respectively, and the difference was not significant (χ2=0.64, P=0.591), the grade of the Clavien-Dindo complications had no significant difference (χ2=0.63, P=0.592). ④ None of the patients died following operation in the LAG group and one case died in the OG group because of the respiratory and circulatory failure caused by the pulmonary embolism. Conclusion Preliminary results of limited cases in this study show that LAG in the elderly patients with gastric cancer could reduce intraoperative blood loss, shorten the first flatus time or the first feeding time, and postoperative hospitalization stay, could obtain same radical effect without increasing incidence of postoperative complications as compared with OG, so it is safety and feasible.
Objective To summarize clinical features, imaging findings, diagnosis, treatment, and prognosis of patients with hepatic focal nodular hyperplasia. Method The clinical data of patients with hepatic focal nodular hyperplasia who underwent hepatectomy from July 2014 to July 2016 in the Xiangya Hospital of Central South University were analyzed retrospectively. Results There were 12 males and 19 females in the 31 patients with hepatic focal nodular hyperplasia, the male-to-female ratio was 1∶1.58. The age was from 15 to 67 years old with (39.7±11.5) years old. Physical examination found 21 cases, there were symptoms in 10 cases. Laboratory examination: only 2 patients with long-term drinking history had mild AST abnormality, HBsAgs of 6 cases were positive, CA19-9 level of one patient was slightly increased (40.54 kU/L). Thirteen patients with hepatic focal nodular hyperplasia were diagnosed by imaging examination, the diagnostic rate of MRI was significantly higher than that of color Doppler ultrasound (P<0.05) or CT (P<0.05). The diameter of the lesions ranged from 2 cm to 11 cm with (4.6±2.1) cm. All lesions were resected, including 13 cases by laparoscopic hepatectomy, and 18 cases by laparotomy. Compared with by the laparotomy, the intraoperative blood loss was less (P<0.05), the hospital stay and intestinal exhaust time were shorter (P<0.05) by the laparoscopic hepatectomy. Twenty-nine patients were followed up from 3 to 24 months, no patient died, the quality of life was better, no recurrence and metastasis happened. Conclusions Hepatic focal nodular hyperplasia is benign lesion, it has a good prognosis, generally without clinical symptoms, its laboratory feature has no abnormality. The combination of multiple imagings and pathological diagnosis could improve diagnosis rate. Surgical resection should be performed for suspected malignant tumor or other hepatic occupying lesions. Laparoscopic surgery has some advantages of quick recovery and less bleeding for it.
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.
ObjectiveTo investigate perioperative safety of laparoscopic pancreaticoduodenectomy (LPD) in elderly patients (age ≥70 years old).MethodsThe retrospective cohort study was conducted. The clinicopathologic data of the patients underwent LPD and open pancreaticoduodenectomy (OPD) in the Affiliated Hospital of North Sichuan Medical College from January 2016 to December 2019 were collected. The patients who met the inclusion and exclusion criteria were divided into LPD with aged ≥70 years old group (group A), OPD with aged ≥70 years old group (group B), and LPD with aged <70 years old group (group C). The baseline data, intraoperative situations, and postoperative situations were compared between the group A and group B, and between the group A and group C, respectively.Results① There were no statistic differences in the age, gender, body mass index, hemoglobin, albumin, and total bilirubin, American Society of Anesthesiologists (ASA) grade, and comorbidity index before operation between the group A and group B (P>0.05). However, there were statistic differences in the hemoglobin, albumin, ASA grade, and comorbidity index before operation between the group A and group C (P<0.05). ② There were no significant differences in the operation time between the group A and group B (P>0.05), but the intraoperative blood loss of the group A was significantly less than the group B (P<0.05). The operation time, intraoperative blood loss, and conversion rate had no significant differences between the group A and group C (P>0.05). ③ There were no significant differences in the pathological pattern, tumor size, R0 resection rate, reoperative rate, and postoperative 90 d mortality between the group A and group B, and between the group A and group C, respectively. For the elderly patients, cases in the ICU, overall complications, specific complications (except for delayed gastric emptying) and Clavien-Dindo classification of complication after operation had no significant differences between the group A and group B (P>0.05), but there were more harvesting lymph nodes, lower postoperative pain score, shorter postoperative hospital stay, and less delayed gastric emptying cases in the group A than the group B (P<0.05). For the patients accepted LPD, there were no significant differences in the harvesting lymph nodes, postoperative pain score, postoperative hospital stay, and specific complications (except for pulmonary infection rate) between the group A and the group C (P>0.05), but the postoperative cases in the ICU were more, pulmonary infection rate was higher, overall complications rate and the ratio of Clavien-Dindo Ⅲ–Ⅳ classification of complication were higher in the group A as compared with the group C (P<0.05). ConclusionCompared with OPD, LPD might have some advantages in blood loss, harvesting lymph nodes, and recovery after surgery, even though perioperative safety of LPD in elderly patients is inferior to younger patients.
ObjectiveTo investigate the clinical feasibility and value of laparoscopic precise segment Ⅳ hepatectomy by guiding of indocyanine green (ICG) fluorescence imaging via ligamenta teres hepatis. MethodThe clinicopathologic data of patients with liver cancer treated in the Department of Liver Surgery of West China Hospital of Sichuan University from January 2017 to December 2021 who underwent precise segment Ⅳ hepatectomy by the guidance of ICG fluorescence imaging through the ligamenta teres hepatis were collected retrospectively. ResultsA total of 6 patients were collected, including 5 males and 1 female. The age ranged from 42 to 78 years. All 6 patients were successfully completed using laparoscopic precise segment Ⅳ hepatectomy by guiding of ICG fluorescence imaging via ligamenta teres hepatis. The operation time was (200±30) min, the intraoperative bleeding was (100±20) mL, and there were no intraoperative blood transfusion, postoperative liver failure, postoperative pneumonia, incision infection, bile leakage, postoperative bleeding, and other complications. The postoperative hospital stay was (7±2) d. One patient with positive microvascular invasion was found after operation and recurred at 38 months after operation, then treated by radiofrequency ablation and didn’t recur. No patient died during the follow-up period in 6 patients. ConclusionFrom results of limited cases in this study, laparoscopic precise segment Ⅳ hepatectomy by guiding of ICG fluorescence imaging via ligamenta teres hepatis is safe, feasible, and effective.
