Objective To explore the hepatic artery variations encountered in laparoscopic pancreaticoduodenectomy (LPD) surgery and its significance. Methods The clinical datas of 26 patients who underwent LPD from January 2020 to January 2023 were retrospectively collected. Preoperative evaluation of hepatic artery variability and its types based on relevant clinical and imaging data, as well as targeted measures taken during surgery, and patients’ prognosis were analyzed. Results According to preoperative abdominal enhanced CT, arterial computer tomography angiography imaging and intraoperative skeletonization of the hepatoduodenal ligament, hepatic artery variation was found in 9 of 26 patients undergoing LPD. The left hepatic artery was substituted in 1 case, the right hepatic artery was substituted in 2 cases, 2 cases were the left accessory hepatic artery, and the common hepatic artery originated from the superior mesenteric artery in 3 cases. There was 1 case, right hepatic artery coming from the abdominal aorta, whose arterial variation was not included in the traditional typing. The variant hepatic artery from superior mesenteric artery was separated by posterior approach during operation, and the variant hepatic artery from left gastric artery was separated by anterior approach during operation. Nine patients with hepatic artery variation recovered well after operation, and no serious complications occurred. Conclusions Various hepatic artery variations during LPD need to be carefully evaluated before surgery. During surgery, it should be determined whether to retain the mutated blood vessel based on its diameter and changes in liver blood flow after occlusion, so that reasonable operation can be performed during the operation to avoid hepatic artery damage.
摘要:目的:探討腹腔鏡膽囊切除術(laparoscopic cholecystectomy, LC)后發生嚴重并發癥的原因、治療措施和經驗教訓。方法:分析 2007 年 8 月至2009 年 4月期間華西醫院膽道外科收治的LC術后發生嚴重并發癥的7例患者的臨床資料。結果:2例繼發性膽總管結石合并化膿性膽管炎患者,采用內鏡下十二指腸乳頭切開(endoscopic sphincterotomy, EST)取出結石;3例膽道損傷患者,均進行肝門膽管成形和肝總管空腸吻合術;1例絞窄性腸梗阻患者,切除壞死空腸管后,行空腸對端吻合術;以上6例患者均順利出院,隨訪8～20個月,均生活良好。1例患者LC術后發生肺動脈栓塞,積極搶救后因呼吸衰竭而死亡。結論:術中仔細輕柔的操作以及辯清肝總管、膽總管與膽囊管的三者關系是預防LC術后發生嚴重并發癥的關鍵。合理可行的治療措施是提高發生并發癥的患者生活質量的保障。LC術時,膽道外科醫生思想上要高度重視,不可盲目追求速度,必要時及時中轉開腹。Abstract: Objective: To investigate the causes and therapeutic measures and the experience and lesson of sever complications after laparoscopic cholecystectomy (LC). Methods:Clinical data of 7 patients with severe complications after LC from August 2007 to April 2009 were analyzed retrospectively. The clinical data was got from biliary department of West China Hospital. Results: Two cases of secondary common bile duct stone with acute suppurative cholangitis got cured by endoscopic sphincterotomy. Three cases of severe bile duct injury after LC had stricture of the hilar bile duct, and all of the cases were performed RouxenY hepaticojejunostomy with the diameter of stoma 2.03.0 centimeters. One case of strangulating intestinal obstruction was cured through jejunum endtoend anastomosis after cutting off the necrotic jejunum. All of the above 6 patients recovered well. Following up for 820 months, all lived well. One patient got pulmonary embolism after LC and dead of respiratory failure after active rescue. Conclusion: Carefully making operation and distinguishing the relationship of hepatic bile duct and common bile duct and the duct of gallbladder are the key points to prevent sever complications during LC. Reasonable and feasible treatment is the ensurement of increasing the living quality of the patients with sever complications after LC. And the surgeons of biliary department must have a correct attitude toward LC and should concern think highly during LC and should not pursue speed blindly. In necessary, the operation of LC should be turned into open cholecystectomy.
ObjectiveTo compare the clinical effect of laparoscopic Heller myotomy (LHM) combined with Dor fundoplication and peroral endoscopic myotomy (POEM) in treatment of patients with achalasia.MethodsThe clinical data of 67 patients with achalasia from January 2014 to December 2018 in the Affiliated Hospital of Xuzhou Medical University were retrospectively analyzed. Among them, 19 patients received the LHM combined with Dor fundoplication (LHM group), 48 patients received the POEM (POEM group). The clinical efficacy and safety of the two groups were compared.ResultsThere were no significant differences in the baseline data such as the gender, age, course of disease, body mass index, preoperative Eckardt score, preoperative maximum diameter of esophagus, and previous treatment history between the two groups (P>0.05). There were no significant differences in the operation time, bleeding volume, the Eckardt points at 3 and 12 months after operation, the decrease degree of maximum diameter of esophagus, complications (except for gastroesophageal reflux, P=0.029), and recurrence rate between the two groups (P>0.05). The total hospitalization time, postoperative hospitalization time, and total hospitalization costs of the POEM group were lower than those of the LHM group (P<0.05).ConclusionsBoth LHM and POEM could effectively relieve clinical symptoms, short-term efficacy and safety of the two kinds of operations are similar. Postoperative recovery of POEM is fast and hospitalization cost is less, but incidence of gastroesophageal reflux is higher.
Objective To evaluate the safety and efficacy of primary closure (PC) and T-tube drainage (TD) after laparoscopic common bile duct exploration (LCBDE). Methods The randomized controlled trials of PC and TD after LCBDE were retrieved from the Cochrane Library, MEDLINE, EMBASE, and Science Citation Index Expanded until April 2015. All calculations and statistical tests were performed using ReviewerManager 5.2 software. Results Both of the two groups had no postoperative deaths within 30 days. The operative time and hospital stay of PC gourp were shorter than TD group statistically〔OR=–24.76, 95CI (–29.21, –20.31),P<0.000 01〕and〔OR=–2.68, 95%CI (–3.69, –1.67),P<0.000 01〕. The reoperative rate of PC group was lower than that of TD group, and the difference was statistically significant〔OR=0.20, 95%CI (0.05, 0.81),P=0.02〕. There was no significant difference between the two groups in the occurrence of postoperative severe complications〔OR=0.54, 95%CI (0.26, 1.12),P=0.10〕. Conclusions Compared with the TD group, the operative time and hospitalization time are shorer in PC group, and complication rate is similar, but the cost of treatment of the TD group is higher than PC group, so after LCBDE a primary closure of common bile duct is safe and effective method.
Objective
To evaluate the safety and efficacy of laparoscopic-assisted gastrectomy (LAG) comparing with conventional open gastrectomy (COG) in elderly patients with gastric cancer.
Methods
Databases included PubMed, EMBASE, Web of Science, Cochrane Library, CNKI, Wanfang, and VIP were searched to collect the case-control studies about LAG versus COG for elderly patients with gastric cancer, and the searched time was from inception to May 2017. Then meta-analysis was performed by using RevMan 5.2 software.
Results
Finally, ten case-control studies included 1 522 patients were enrolled. There were 757 patients in observation group (underwent LAG) and 765 patients in control group (underwent COG). Results of meta-analysis showed that: the observation group was associated with less intraoperative blood loss ［MD=–121.12, 95% CI was (–179.93, –62.31), P<0.000 1］, more harvested lymph nodes ［MD=1.62, 95% CI was (0.60, 2.65), P=0.002］, shorter time to the first ambulation ［SMD=–2.58, 95% CI was(–4.58, –0.58), P=0.01］, shorter the postoperative intestinal function recovery time ［SMD=–0.85, 95% CI was (–1.20, –0.51), P<0.000 01］, shorter the time of oral intake ［MD=–0.90, 95% CIwas (–1.27, –0.52), P<0.000 01］, shorter hospital stay ［MD=–4.03,95% CI was (–5.62, –2.44), P<0.000 01］, lower incidences of overall postoperative complications ［OR=0.49, 95% CI was (0.38,0.64), P<0.000 01］, surgical-related complications ［OR=0.54, 95% CI was (0.39, 0.74), P=0.000 1］, incision relatedcomplications ［OR=0.42, 95% CI was (0.22, 0.81), P=0.010］, and respiratory complications ［OR=0.60, 95% CI was (0.38, 0.95), P=0.03］, but there was no significant difference on the operative time ［MD=8.36, 95% CI was (–10.97, 27.69), P=0.40］ and incidence of anastomotic fistula ［OR=0.60, 95% CI was (0.27, 1.31), P=0.20］.
Conclusions
The available evidences suggest that LAG is equally safe and feasible compared with COG, it has a significant advantages in reducing intraoperative blood loss and ensuring the number of lymph node dissected during surgery, with less trauma, shorter postoperative hospital stay, lower overall postoperative complications rate, and other short-term efficacy advantages.
ObjectiveTo investigate the feasibility of hand-assisted laparoscopic surgery in radical gastrectomy for gastric cancer. MethodsThe data of two cases undergoing hand-assisted laparoscopic radical gastrectomy for gastric cancer, including operative time, operation related complications, intraoperative bleeding volumes, number of harvested lymph nodes, postoperative complications, time to restoration of bowel function, and length of postoperative hospital stay, etc, were retrospectively analyzed. ResultsTwo patients had undergone the successful hand-assisted laparoscopic radical total gastrectomy and distal gastrectomy without operation related complications. The operative time was 310 min and 220 min, respectively. While, the intraoperative bleeding volume was 120 ml and 80 ml with the number of harvested lymph node being 38 and 52, respectively. There were no postoperative bleeding, intestinal fistula, and anastomotic leakage， etc. The patients were discharged with smooth and fully recovery. ConclusionThe application of hand-assisted laparoscopic surgery in radical gastrectomy for gastric cancer is feasible and safe. However, the effectiveness needs further exploring.
ObjectiveTo evaluate efficacy and safety of laparoscopic Glissonean pedicle transection anatomic hepatectomy using indocyanine green (ICG) fluorescence imaging.MethodThe retrospective analysis was made on the preoperative clinical data, surgical treatment and postoperative status of a patient with hepatocellular carcinoma who underwent the laparoscopic Glissonean pedicle transection anatomic hepatectomy using the ICG fluorescence imaging technology in the Department of Liver Surgery, West China Hospital of Sichuan University.ResultsAccording to the preoperative history, imaging and laboratory examinations, the diagnosis of hepatocellular carcinoma was considered. The intraoperative exploration revealed that there was only one tumor located in the segment Ⅳ and was superficial. The ICG fluorescence imaging was used to perform the Glissonean pedicle transection anatomic hepatectomy. The postoperative pathological diagnosis was consistent with hepatocellular carcinoma without serious complications. The patient recovered well. No recurrence was found in the follow-up period up to 6 months.ConclusionsLaparoscopic Glissonean pedicle transection anatomic hepatectomy using ICG fluorescence technology can be used as a safe and precise treatment to solve problems such as bleeding during operation, difficult determination of tumor boundary, and whether having residual tumor in surgical margin.
Objective
To explore the risk factors of postoperative portal vein system thrombus (PVST) after laparoscopic splenectomy in treatment of portal hypertension and hypersplenism.
Methods
Clinical data of 76 patients with portal hypertension and hypersplenism who underwent laparoscopic splenectomy in the Sichuan Provincial People’s Hospital from January 2012 to January 2017 were analyzed.
Results
There were 31 patients suffered from PVST (PVST group), and other 45 patients enrolled in non-PVST group.There were significant differences on age, diameter of splenic vein, diameter of portal vein, blood flow velocity of portal vein, level of D-dimer, and platelet count between the PVST group and the non-PVST group (P<0.05), but there were no significant difference on gender, Child-Pugh classification, etiology of cirrhosis, operation time, intraoperative blood loss, postoperative complications, and prothrombin time between the two groups (P>0.05). Multivariate logistic regression analysis showed that, patients with age >50 years (RR=1.31, P=0.02), splenic vein diameter >12 mm ( RR=1.29, P<0.01), portal vein diameter >13 mm (RR=1.55, P=0.01), blood flow velocity of portal vein <18 cm/s ( RR=1.47, P<0.01), increases level of D-dimer (RR=2.89, P=0.03), and elevated platelet count (RR=1.82 P=0.02) had higher risk of postoperative PVST than those patients with age ≤50 years, splenic vein diameter ≤12 mm, portal vein diameter ≤13 mm, blood flow velocity of portal vein ≥18 cm/s, normal level of D-dimer and platelet count.
Conclusion
For patients with portal hypertension and hypersplenism who underwent laparoscopic splenectomy, we should pay more attention to the risk factor, such as D-dimer and so on, to avoid the occurrence of postoperative PVST.
ObjectiveTo summarize the key technical points, applicability, feasibility, and safety of laparoscopic spleen-preserving distal pancreatectomy (LSPDP).MethodA retrospective analysis was performed for the clinical data of 22 patients who were admitted to the Affiliated Hospital of North Sichuan Medical College from September 2016 to November 2019, all patients planned to receive LSPDP.ResultsTwenty of the 22 patients successfully completed LSPDP, and 2 patients converted to laparotomy. One patient was transferred to laparotomy to suture the damaged splenic artery. The spleen was observed to have no ischemia and the spleen preservation operation was continued. One patient was converted to laparotomy due to the difficulty of dissecting the tail of the pancreas which caused by severe abdominal adhesion. The operation time of LSPDP patients was (191±86) minutes (170–480 min), intraoperative blood loss was (365±50) mL (200–1 000 mL), and postoperative hospital stay was (9.9±2.6) days (7–16 d). Six patients of pancreatic fistula occurred after operation, including 3 cases of biochemical fistula, which were cured and discharged after symptomatic treatment, 3 cases of grade B pancreatic fistula, who all improved after anti-inflammatory, acid suppression, enzyme suppression, and double catheter drainage. Twenty patients were interviewed after the operation, and the follow-up time was 3–24 months (median of 15 months). During the follow-up period, no patient had recurrence or metastasis.ConclusionsUnder the conditions of strict screening of suitable cases, adequate preoperative imaging evaluation, intraoperative fine manipulation, and the application of appropriate operating instruments and cutting closure devices, LSPDP is safe and feasible to treat benign tumors of the pancreatic body and tail and some borderline tumors. During the operation, attention should be paid to the reasonable treatment and protection of splenic arteries and veins.
ObjectiveTo evaluate the efficacy of robotic intersphincteric resection (ISR) for rectal cancer.MethodsA literature search was performed using the China biomedical literature database, Chinese CNKI, Wanfang, PubMed, Embase, and the Cochrane library. The retrieval time was from the establishment of databases to April 1, 2019. Related interest indicators were brought into meta-analysis by Review Manager 5.2 software.ResultsA total of 510 patients were included in 5 studies, including 273 patients in the robot group and 237 patients in the laparoscopic group. As compared to the laparoscopic group, the robot group had significantly longer operative time [MD=43.27, 95%CI (16.48, 70.07), P=0.002], less blood loss [MD=–19.98.27, 95%CI (–33.14, –6.81), P=0.003], lower conversion rate [MD=0.20, 95%CI (0.04, –0.95), P=0.04], less lymph node harvest [MD=–1.71, 95%CI (–3.21, –0.21), P=0.03] and shorter hospital stay [MD=–1.61, 95%CI (–2.26, –0.97), P<0.000 01]. However, there were no statistically significant differences in the first flatus [MD=–0.01, 95%CI (–0.48, 0.46), P=0.96], time to diet [MD=–0.20, 95%CI (–0.67, 0.27), P=0.41], incidence of complications [OR=0.76, 95%CI (0.50, 1.14), P=0.18], distal resection margin [MD=0.00, 95%CI (–0.17, 0.17), P=0.98] and positive rate of circumferential resection margin [OR=0.61, 95%CI (0.27, 1.37), P=0.23].ConclusionsRobotic and laparoscopic ISR for rectal cancer shows comparable perioperative outcomes. Compared with laparoscopic ISR, robotic ISR has the advantages of less blood loss, lower conversion rate, and longer operation times. These findings suggest that robotic ISR is a safe and effective technique for treating low rectal cancer.
