Optimal choice of stapler and digestive tract reconstruction method after distal gastrectomy for gastric cancer:A prospective case–control study

BACKGROUND Gastric cancer is the most common cause of cancer-related deaths,and is classified according to its location in the proximal,middle,or distal stomach.Surgical resection is the primary approach for treating gastric cancer.This prospective study aimed to determine the best reconstruction method after distal gastrectomy for gastric cancer.AIM To explore the efficacy of different staplers and digestive tract reconstruction(DTR)methods after radical gastrectomy and their influence on prognosis.METHODS Eighty-seven patients who underwent radical gastrectomy for distal gastric cancer at our institution between April 2017 and April 2020 were included in this study,with a follow-up period of 12-26 mo.The patients were assigned to four groups based on the stapler and DTR plan as follows:BillrothⅠ(B-I)reconstruction+linear stapler group(group A,22 cases),B-I reconstruction+circular stapler group(group B,22 cases),Billroth II(B-II)reconstruction+linear stapler group(group C,22 cases),and B-II reconstruction+circular stapler group(group D,21 cases).The pathological parameters,postoperative gastrointestinal function recovery,postoperative complications,and quality of life(QOL)were compared among the four groups.RESULTS No significant differences in the maximum diameter of the gastric tumors,total number of lymph nodes dissected,drainage tube removal time,QLQ(QOL questionnaire)-C30 and QLQ-STO22 scores at 1 year postoperatively,and incidence of complications were observed among the four groups(P>0.05).However,groups A and C(linear stapler)had significantly lower intraoperative blood loss and significantly shorter anastomosis time,operation time,first fluid diet intake time,first exhaust time,and length of postoperative hospital stay(P<0.05)than groups B and D(circular stapler).CONCLUSION Linear staplers offer several advantages for postoperative recovery.B-I and B-II reconstruction methods had similar effects on QOL.The optimal solution can be selected according to individual conditions and postoperative convenience.

Three-dimensional computed tomography reconstruction diagnosed digestive tract perforation and acute peritonitis caused by Monopterus albus:A case report

BACKGROUND Few reports have described living foreign bodies in the human body.The current manuscript demonstrates that computed tomography(CT)is an effective tool for accurate preoperative evaluation of living foreign bodies in clinic.The threedimensional(3D)reconstruction technology could clearly display anatomical structures,lesions and adjacent organs,improving diagnostic accuracy and guiding the surgical decision-making process.CASE SUMMARY Herein we describe a 68-year-old man diagnosed with digestive tract perforation and acute peritonitis caused by a foreign body of Monopterus albus.The patient pre-sented to the emergency department with complaints of dull abdominal pain,profuse sweating and a pale complexion during work.A Monopterus albus had entered the patient’s body through the anus two hours ago.During hospitalization,the 3D reconstruction technology revealed a perforation of the middle rectum complicated with acute peritonitis and showed a clear and complete Monopterus albus bone morphology in the abdominal and pelvic cavities,with the Monopterus albus biting the mesentery.Laparoscopic examination detected a large(diameter of about 1.5 cm)perforation in the mid-rectum.It could be seen that a Monopterus albus had completely entered the abdominal cavity and had tightly bitten the mesentery of the small intestine.During the operation,the dead Monopterus albus was taken out.CONCLUSION The current manuscript demonstrates that CT is an effective tool for accurate preoperative evaluation of living foreign bodies in clinic.

Digestive tract reconstruction options after laparoscopic gastrectomy for gastric cancer

In addition to the popularity of laparoscopic gastrectomy(LG),many reconstructive procedures after LG have been reported.Surgical resection and lymphatic dissection determine long-term survival;however,the election of a reconstruction procedure determines the postoperative quality of life for patients with gastric cancer(GC).Presently,no consensus exists regarding the optimal reconstructive procedure.In this review,the current state of digestive tract reconstruction after LG is reviewed.According to the determining influence of the tumor site on the procedures of surgical resection and reconstruction,we divide these reconstruction procedures into three categories consistent with the resection procedures.We focus on the technical tips of every reconstruction procedure and examine the surgical outcomes(length of surgery and blood loss)and postoperative complications(anastomotic leakage and stricture)to facilitate gastrointestinal surgeons to understand the merits and demerits of every reconstruction procedure.

Digestive tract reconstruction pattern as a determining factor in postgastrectomy quality of life

Postgastrectomy quality of life (QoL) is affected by various symptoms, and compared with the preoperative baseline QoL, is typically impaired for the first 6 mo after surgery. Thereafter, improvement to a stable QoL is observed at approximately 12 mo postoperatively. We consider the digestive tract reconstruction pattern to be a determining factor in postgastrectomy QoL among gastric cancer patients, and believe it requires further discussion. Proximal gastrectomy is associated with the worst postoperative QoL among gastrectomy procedures and should be performed cautiously. The trend of better QoL provided by the pouch procedure of total gastrectomy requires further robust support. Whether the use of Billroth-I gastroduodenostomy or Roux-en-Y gastrojejunostomy for distal gastrectomy is optimal remains controversial, but Roux-en-Y gastrojejunostomy is likely to be preferable.

T-tube vs no T-tube for biliary tract reconstruction in adult orthotopic liver transplantation:An updated systematic review and metaanalysis

BACKGROUND Whether to use a T-tube for biliary anastomosis during orthotopic liver transplantation(OLT)remains a debatable question.Some surgeons chose to use a T-tube because they believed that it reduces the incidence of biliary strictures.Advances in surgical techniques during the last decades have significantly decreased the overall incidence of postoperative biliary complications.Whether using a T-tube during OLT is still associated with the reduced incidence of biliary strictures needs to be re-evaluated.AIM To provide an updated systematic review and meta-analysis on using a T-tube during adult OLT.METHODS In the electronic databases MEDLINE,PubMed,Scopus,ClinicalTrials.gov,the Cochrane Library,the Cochrane Hepato-Biliary Group Controlled Trails Register,and the Cochrane Central Register of Controlled Trials,we identified 17 studies(eight randomized controlled trials and nine comparative studies)from January 1995 to October 2020.The data of the studies before and after 2010 were separately extracted.We chose the overall biliary complications,bile leaks or fistulas,biliary strictures(anastomotic or non-anastomotic),and cholangitis as outcomes.Odds ratios(ORs)with 95%confidence intervals(CIs)were calculated to describe the results of the outcomes.Furthermore,the test for overall effect(Z)was used to test the difference between OR and 1,where P≤0.05 indicated a significant difference between OR value and 1.RESULTS A total of 1053 subjects before 2010 and 1346 subjects after 2010 were included in this meta-analysis.The pooled results showed that using a T-tube reduced the incidence of postoperative biliary strictures in studies before 2010(P=0.012,OR=0.62,95%CI:0.42-0.90),while the same benefit was not seen in studies after 2010(P=0.60,OR=0.76,95%CI:0.27-2.12).No significant difference in the incidence of overall biliary complications(P=0.37,OR=1.41,95%CI:0.66-2.98),bile leaks(P=0.89,OR=1.04,95%CI:0.63-1.70),and cholangitis(P=0.27,OR=2.00,95%CI:0.59-6.84)was observed between using and not using a T-tube before 2010.However,using a T-tube appeared to increase the incidence of overall biliary complications(P=0.049,OR=1.49,95%CI:1.00-2.22),bile leaks(P=0.048,OR=1.91,95%CI:1.01-3.64),and cholangitis(P=0.02,OR=7.21,95%CI:1.37-38.00)after 2010.A random-effects model was used in biliary strictures(after 2010),overall biliary complications(before 2010),and cholangitis(before 2010)due to their heterogeneity(I2=62.3%,85.4%,and 53.6%,respectively).In the sensitivity analysis(only RCTs included),bile leak(P=0.66)lost the significance after 2010 and a random-effects model was used in overall biliary complications(before 2010),cholangitis(before 2010),bile leaks(after 2010),and biliary strictures(after 2010)because of their heterogeneity(I2=92.2%,65.6%,50.9%,and 80.3%,respectively).CONCLUSION In conclusion,the evidence gathered in our updated meta-analysis showed that the studies published in the last decade did not provide enough evidence to support the routine use of T-tube in adults during OLT.

Effects on the pouch of different digestive tract reconstruction modes assessed by radionuclide scintigraphy

AIM: To determine the effect of three digestive tract reconstruction procedures on pouch function, after radical surgery undertaken because of gastric cancer, as assessed by radionuclide dynamic imaging. METHODS: As a measure of the reservoir function, with a designed diet containing technetium-99m (99mTc), the emptying time of the gastric substitute was evaluated using a 99mTc-labeled solid test meal. Immediately after the meal, the patient was placed in front of a γ camera in a supine position and the radioactivity was measured over the whole abdomen every minute. A frame image was obtained. The emptying sequences were recorded by the microprocessor and then stored on a computer disk. According to a computer processing system, the half-emptying actual curve and the fitting curve of food containing isotope in the detected region were depicted, and the half-emptying actual curves of the three reconstruction procedures were directly compared. RESULTS: Of the three reconstruction procedures, the half-emptying time of food containing isotope in the Dual Braun type esophagojejunal anastomosis procedure (51.86±6.43 min) was far closer to normal, signif icantly better than that of the proximal gastrectomy orthotopic reconstruction (30.07±15.77 min, P=0.002) and P type esophagojejunal anastomosis (27.88±6.07 min, P=0.001) methods. The half-emptying actual curve and f itting curves for the Dual Braun type esophagojejunal anastomosis were fairly similar while those of the proximal gastrectomy orthotopic reconstruction and P type esophagojejunal anastomosis were obviously separated, which indicated bad food conservation in the reconstructed pouches. CONCLUSION: Dual Braun type esophagojejunal anastomosis is the most useful of the three procedures for improving food accommodation in patients with a pouch and can retard evacuation of solid food from the reconstructed pouch.

Modified hepatic outflow tract reconstruction in piggyback liver transplantation

OBJECTIVE: To summarize the experience in modified reconstruction of the hepatic outflow tract during piggyback liver transplantation at our hospital. METHODS: The clinical data on 67 patients undergoing piggyback liver transplantation with modified hepatic outflow tract reconstruction from January 1999 to October 2002 were analyzed retrospectively. RESULTS: In this group, 7 patients (10. 45%) died perioperatively. Complications included: pulmonary infection (38 patients); multiple organ system failure (10), intraperitoneal bleeding (6), acute respiratory distress syndrome (14), thrombosis of the hepatie artery (1), and bile leakage (1). No hepatic outflow occluded. Two recipients survived for over 3 years, 8 over 2 years, and 19 over a year. CONCLUSION: Modified hepatic outflow reconstruction in piggyback live transplantation may increase the success rate of liver transplantation and decrease technical complications.

Tissue engineering for urinary tract reconstruction and repair: Progress and prospect in China

Several urinary tract pathologic conditions,such as strictures,cancer,and obliterations,require reconstructive plastic surgery.Reconstruction of the urinary tract is an intractable task for urologists due to insufficient autologous tissue.Limitations of autologous tissue application prompted urologists to investigate ideal substitutes.Tissue engineering is a new direction in these cases.Advances in tissue engineering over the last 2 decades may offer alternative approaches for the urinary tract reconstruction.The main components of tissue engineering include biomaterials and cells.Biomaterials can be used with or without cultured cells.This paper focuses on cell sources,biomaterials,and existing methods of tissue engineering for urinary tract reconstruction in China.The paper also details challenges and perspectives involved in urinary tract reconstruction.

Pancreaticojejunostomy, hepaticojejunostomy and double Roux-en-Y digestive tract reconstruction for benign pancreatic diseases

Surgery such as digestive tract reconstruction is usually required for pancreatic trauma and severe pancreatitis as well as malignant pancreatic lesions. The most common digestive tract reconstruction techniques (e.g., Child&#x02019;s type reconstruction) for neoplastic diseases of the pancreatic head often encompass pancreaticojejunostomy, choledochojejunostomy and then gastrojejunostomy with pancreaticoduodenectomy, whereas these techniques may not be applicable in benign pancreatic diseases due to an integrated stomach and duodenum in these patients. In benign pancreatic diseases, the aforementioned reconstruction will not only increase the distance between the pancreaticojejunostomy and choledochojejunostomy, but also the risks of traction, twisting and angularity of the jejunal loop. In addition, postoperative complications such as mixed fistula are refractory and life-threatening after common reconstruction procedures. We here introduce a novel pancreaticojejunostomy, hepaticojejunostomy and double Roux-en-Y digestive tract reconstruction in two cases of benign pancreatic disease, thus decreasing not only the distance between the pancreaticojejunostomy and choledochojejunostomy, but also the possibility of postoperative complications compared to common reconstruction methods. Postoperatively, the recovery of these patients was uneventful and complications such as bile leakage, pancreatic leakage and digestive tract obstruction were not observed during the follow-up period.

Research progress in three-dimensional reconstruction of the rat spinal tract

BACKGROUND： Recently, three-dimensional （3D） reconstruction of the corticospinal tract has been attempted in treatment for corticospinal tract injury. However, results remain unsatisfactory. OBJECTIVE： This manuscript reviews technique progress and problems in 3D reconstruction of rat spinal tracts, as well as 3D reconstruction of human spinal tracts. RETRIEVAL STRATEGY： Using the keywords ＂rat, spinal tracts, three-dimensional reconstruction＂, the PubMed database was searched for English articles pertaining to 3D reconstruction of the rat spinal tract that were published between January 1996 and January 2007. Meanwhile, the above-mentioned keywords in Chinese were also used to search the CNK1 database for articles that were published between January 1999 and January 2007. Inclusion criteria： manuscripts that addressed the study of 3D reconstruction of the rat spinal tract and review articles. Exclusion criteria： old and repetitive articles. All manuscripts were initially evaluated, followed by extensive review. LITERATURE EVALUATION： A total of 154 related manuscripts were collected; a total of 27 were evaluated and reviewed for the present review. One manuscript assessed rat behavioral functions, four were experimental reports addressing micro-3D reconstruction techniques, ten were experiment reports about image analysis of rat corticospinal tracts, and twelve were experiment articles related to image processing of serial spinal cord sections. DATA SYNTHESIS： Rat spinal cord sections were obtained through section staining or magnetic resonance imaging （MRI） techniques, specifically localizing the inner tracts. Software was used to construct 3D reconstruction from the serial sections to observe and analyze rat spinal cord structures. The rat spinal cord is small, with complicated inner tracts, which makes accurate 3D reconstruction difficult. CONCLUSION： The assembly of 3D reconstructions from rat spinal cord serial sections and the visualization of the inner tracts are imperative for studying rat spinal cord diseases.

Coronary Artery Complications after Right Ventricular Outflow Tract Reconstruction Surgery

Background:Mechanisms and clinical manifestations of coronary artery complications after right ventricular outflow tract reconstruction surgery are not well known.Methods:Patients who had coronary artery complications after pulmonary valve replacement or the Rastelli procedure at a single tertiary centre were retrospectively analysed.Results:Coronary artery complications were identified in 20 patients who underwent right ventricular outflow tract reconstruction surgery.The median age at diagnosis of coronary artery complication was 21 years(interquartile range:13–25 years).Mechanisms of coronary artery complications were compression by adjacent materials in 12 patients,dynamic compression of intramural course of coronary artery in two patients,and intraoperative injury in six patients.Congenital coronary artery anomalies were identified in 50%(10/20)of patients.Four patients presented with early postoperative haemodynamic instability.Fourteen patients showed late onset symptoms or signs of coronary insufficiency,including chest pain,ventricular dysfunction,or ventricular arrhythmias.Coronary artery stenosis was incidentally found on cardiac computed tomography angiography in two asymptomatic patients.Four patients underwent surgical interventions,and one patient underwent percutaneous coronary intervention for coronary stenosis.One patient with recurrent ventricular tachycardia required an implantable cardioverter-defibrillator.There were two deaths in patients with intraoperative coronary injury.Conclusion:Preoperative coronary evaluation and long-term follow-up for the development of coronary artery complications are required in patients undergoing right ventricular outflow tract reconstruction surgery to prevent ventricular dysfunction,arrhythmias,and death,especially among those with congenital coronary anomalies.

Duct-to-duct biliary reconstruction after radical resection of Bismuth Ⅲ a hilar cholangiocarcinoma

At present, radical resection remains the only effective treatment for patients with hilar cholangiocarcinoma. The surgical approach for R0 resection of hilar cholangiocarcinoma is complex and diverse, but for the biliary reconstruction after resection, almost all surgeons use Roux-en-Y hepaticojejunostomy. A viable alternative to Roux-en-Y reconstruction after radical resection of hilar cholangiocarcinoma has not yet been proposed. We report a case of performing duct-to-duct biliary reconstruction after radical resection of Bismuth Ⅲa hilar cholangiocarcinoma. End-to-end anastomosis between the left hepatic duct and the distal common bile duct was used for the biliary reconstruction, and a singlelayer continuous suture was performed along the bile duct using 5-0 prolene. The patient was discharged favorably without biliary fistula 2 wk later. Evidence for tumor recurrence was not found after an 18 mo follow- up. Performing bile duct end-to-end anastomosis in hilar cholangiocarcinoma can simplify the complex digestive tract reconstruction process.

Clinical efficacy and safety of double-channel anastomosis and tubular gastroesophageal anastomosis in gastrectomy

BACKGROUND With the continuous progress of surgical technology and improvements in medical standards,the treatment of gastric cancer surgery is also evolving.Proximal gastrectomy is a common treatment,but double-channel anastomosis and tubular gastroesophageal anastomosis have attracted much attention in terms of surgical options.Each of these two surgical methods has advantages and disadvantages,so it is particularly important to compare and analyze their clinical efficacy and safety.AIM To compare the surgical safety,clinical efficacy,and safety of double-channel anastomosis and tubular gastroesophageal anastomosis in proximal gastrectomy.METHODS The clinical and follow-up data of 99 patients with proximal gastric cancer who underwent proximal gastrectomy and were admitted to our hospital between January 2018 and September 2023 were included in this retrospective cohort study.According to the different anastomosis methods used,the patients were divided into a double-channel anastomosis group(50 patients)and a tubular gastroesophageal anastomosis group(49 patients).In the double-channel anastomosis,Roux-en-Y anastomosis of the esophagus and jejunum was performed after proximal gastric dissection,and then side-to-side anastomosis was performed between the residual stomach and jejunum to establish an antireflux barrier and reduce postoperative gastroesophageal reflux.In the tubular gastroesophageal anastomosis group,after the proximal end of the stomach was cut,tubular gastroplasty was performed on the distal stump of the stomach and a linear stapler was used to anastomose the posterior wall of the esophagus and the anterior wall of the stomach tube.The main outcome measure was quality of life 1 year after surgery in both groups,and the evaluation criteria were based on the postgastrectomy syndrome assessment scale.The greater the changes in body mass,food intake per meal,meal quality subscale score,and total measures of physical and mental health score,the better the condition;the greater the other indicators,the worse the condition.The secondary outcome measures were intraoperative and postoperative conditions,the incidence of postoperative long-term complications,and changes in nutritional status at 1,3,6,and 12 months after surgery.RESULTS In the double-channel anastomosis cohort,there were 35 males(70%)and 15 females(30%),33(66.0%)were under 65 years of age,and 37(74.0%)had a body mass index ranging from 18 to 25 kg/m2.In the group undergoing tubular gastroesophageal anastomosis,there were eight females(16.3%),21(42.9%)individuals were under the age of 65 years,and 34(69.4%)had a body mass index ranging from 18 to 25 kg/m2.The baseline data did not significantly differ between the two groups(P>0.05 for all),with the exception of age(P=0.021).The duration of hospitalization,number of lymph nodes dissected,intraoperative blood loss,and perioperative complication rate did not differ significantly between the two groups(P>0.05 for all).Patients in the dual-channel anastomosis group scored better on quality of life measures than did those in the tubular gastroesophageal anastomosis group.Specifically,they had lower scores for esophageal reflux[2.8(2.3,4.0)vs 4.8(3.8,5.0),Z=3.489,P<0.001],eating discomfort[2.7(1.7,3.0)vs 3.3(2.7,4.0),Z=3.393,P=0.001],total symptoms[2.3(1.7,2.7)vs 2.5(2.2,2.9),Z=2.243,P=0.025],and other aspects of quality of life.The postoperative symptoms[2.0(1.0,3.0)vs 2.0(2.0,3.0),Z=2.127,P=0.033],meals[2.0(1.0,2.0)vs 2.0(2.0,3.0),Z=3.976,P<0.001],work[1.0(1.0,2.0)vs 2.0(1.0,2.0),Z=2.279,P=0.023],and daily life[1.7(1.3,2.0)vs 2.0(2.0,2.3),Z=3.950,P<0.001]were all better than those of the tubular gastroesophageal anastomosis group.The group that underwent tubular gastroesophageal anastomosis had a superior anal exhaust score[3.0(2.0,4.0)vs 3.5(2.0,5.0),Z=2.345,P=0.019]compared to the dual-channel anastomosis group.Hemoglobin,serum albumin,total serum protein,and the rate at which body mass decreased one year following surgery did not differ significantly between the two groups(P>0.05 for all).CONCLUSION The safety of double-channel anastomosis in proximal gastric cancer surgery is equivalent to that of tubular gastric surgery.Compared with tubular gastric surgery,double-channel anastomosis is a preferred surgical technique for proximal gastric cancer.It offers advantages such as less esophageal reflux and improved quality of life.

食管癌术后消化道模式重建及饮食训练方案的探讨

目的:探讨食管癌术后消化道模式重建及饮食训练方案。方法:选择2021年7月—2021年10月接受食管癌手术治疗患者70例,采用区组随机化分组方法随机分为对照组和观察组,每组35例。对照组给予常规饮食干预,观察组给予饮食训练干预。分别在干预前、干预2周后、出院时对比两组患者胃肠道症状评分、主观整体营养评估表(PG-SGA)评分、血生化指标及生活质量评分。结果;观察组患者干预2周后、出院时胃肠道症状评分、PG-SGA评分均优于对照组,血生化指标中总蛋白、白蛋白、血红蛋白指标均高于对照组,生活质量评分高于对照组,差异均有统计学意义(P<0.05)。结论:饮食训练方案能够明显减轻食管癌术后患者胃肠道症状,改善营养指标和血生化指标,提升患者生活质量。
