Duodenal stump reinforcement might reduce both incidence and severity of duodenal stump leakage after laparoscopic gastrectomy with Roux-en-Y reconstruction for gastric cancer

Double Half Purse-String Sutures Plus "8" Pattern of Stitching for Prevention of Duodenal Stump Fistula after Laparoscopic Gastrectomy

Background: Duodenal stump fistula represents an infrequent but serious complication after laparoscopic radical gastrectomy with Billroth II or Roux-en-Y reconstruction for gastric cancer. The present study was designed to evaluate the effectiveness of laparoscopic double half purse-string sutures plus "8" pattern of stitching for reinforcement of duodenal stump. Methods: The data of patients undergoing laparoscopic radical gastrectomy with Billroth II or Roux-en-Y reconstruction were retrospectively analyzed between August 2022 and June 2023. According to the different reinforcement methods of duodenal stump, included patients were subdivided into three groups as follows: Group A, duodenal stump was treated with double half purse-string sutures plus "8" pattern of stitching; Group B, duodenal stump was reinforced by continuous suture using a barbed suture; and Group C, duodenal stump without any additional processing. The incidences of duodenal stump fistula between three groups were documented and compared. Moreover, the independent risk factors associated with duodenal stump fistula were analyzed using the logistic regression analysis. Results: No postoperative duodenal stump fistula occurred in Group A, which was significantly different from Group B and Group C (P = .007). In the multivariate analysis, age (odds ratio [OR], 1.191; 95% confidence interval [CI], 1.088-1.303), body mass index (OR, 0.824; 95% CI, 0.727-0.935), and American Society of Anesthesiologists score (OR, 4.495; 95% CI, 1.264-15.992) were the risk factors for duodenal stump fistula. Conclusion: Double half purse-string sutures plus "8" pattern of suture can be conducted in a relatively short operation period and could prevent the incidence of duodenal stump fistula to some extent.

Modified Q-type purse-string suture duodenal stump embedding method for laparoscopic gastrectomy for gastric cancer

OBJECTIVE

This study introduced the modified Q-type purse-string suture duodenal stump embedding method, a convenient way to strengthen the duodenum, and compared it to the conventional one to assess its efficacy and safety.

METHODS

This retrospective analysis examined 612 patients who received laparoscopic gastrectomy for gastric Cancer at a single center. The patients were divided into Not Reinforced Group (n = 205) and Reinforced Group (n = 407) according to the surgical approach to the duodenal stump. The reinforced group was further divided into a modified Q-type purse-string suture embedding method group (QM, n = 232) and a conventional suture duodenal stump embedding method group (CM, n = 175) according to the methods of duodenal stump enhancement. Clinicopathological characteristics, operative variables, and short-term complications were documented and analyzed.

RESULTS

The incidence of duodenal stump leakage(DSL) in the Not Reinforced Group was higher compared to the Reinforced Group, although the difference was not statistically significant [2.4% (5/205) vs 0.7% (3/407), p = 0.339]. Additionally, the Not Reinforced Group exhibited a higher rate of Reoperation due to DSL compared to the Reinforced Group [2 (1.0%) vs. 0, p = 0.046], with one patient in the Not Reinforced Group experiencing mortality due to DSL [1 (0.5%) vs 0, p = 0.158]. Subgroup analysis within the Reinforced Group revealed that the modified Q-type purse-string suture embedding group (QM) subgroup demonstrated statistically significant advantages over the conventional suture embedding group (CM) subgroup. QM exhibited shorter purse-string closure times (4.11 ± 1.840 vs. 6.05 ± 1.577, p = 0.001), higher purse-string closure success rates (93.1% vs. 77.7%, p = 0.001), and greater satisfaction with purse-string closure [224 (96.6%) vs 157 (89.7%), p = 0.005]. No occurrences of duodenal stump leakage were observed in the QM subgroup, while the CM subgroup experienced two cases [2 (1.1%)], though the difference was not statistically significant. Both groups did not exhibit statistically significant differences in secondary surgery or mortality related to duodenal stump leakage.

CONCLUSION

Duodenal Stump Leakage (DSL) is a severe but low-incidence complication. There is no statistically significant relationship between the reinforcement of the duodenal stump and the incidence of DSL. However, laparoscopic reinforcement of the duodenal stump can reduce the severity of fistulas and the probability of Reoperation. The laparoscopic Q-type purse-string suture duodenal stump embedding method is a simple and effective technique that can, to some extent, shorten the operation time and enhance satisfaction with purse-string closure. There is a trend towards reducing the incidence of DSL, thereby improving patient prognosis to a certain extent.

Retrograde drainage for duodenal stump leakage using ileal decompression tube guided by double-balloon endoscopy: a novel case report

BACKGROUND

Duodenal stump leakage is a serious post-gastrectomy complication, and there have been no reports on endoscopic drainage.

CASE PRESENTATION

We report a case of duodenal stump leakage after laparoscopic gastrectomy with Roux-en-Y reconstruction in a 68-year-old man. First-line conservative management was ineffective. Reoperation was performed because of severe abdominal pain and increased ascites. After reoperation, duodenal stump leakage recurred with bleeding from the anterior superior pancreaticoduodenal artery. Coil embolization and pigtail catheter insertion were performed. Furthermore, we retrogradely inserted an ileal tube for tube decompression near the duodenal stump using double-balloon endoscopy for effective drainage. After tube insertion, duodenal stump leakage decreased; on the 47th primary postoperative day, the patient was discharged. The primary postoperative course was uneventful after 1 year and 9 months of follow-up.

CONCLUSIONS

This is the first successful case of duodenal stump leakage treated with retrograde decompression tube insertion near the duodenal stump using double-balloon endoscopy.

Reinforcement methods of duodenal stump after laparoscopic gastrectomy for gastric cancer: A review

Duodenal stump fistula is a rare but dangerous complication of gastric cancer surgery. Reinforcement of the duodenal stump was suggested as a useful method to prevent the occurrence of duodenal stump fistula. Although laparoscopic surgery has been established as a safe procedure for gastric cancer, it is acknowledged that the application of duodenal stump reinforcement is a demanding process in laparoscopic radical gastrectomy. This review aims to provide a concise description of the proposed reinforcement methods of duodenal stump after laparoscopic radical gastrectomy for gastric cancer by summarizing the relevant literature written in English. The thorough knowledge of these reinforcement techniques may help surgeons to find the most suitable reinforcement method of duodenal stump for patients.

Utility and Feasibility of Removing Surgical Staples from the Remnant Stomach or Gastric Conduit during Endoscopic Submucosal Dissection

Objective Endoscopic submucosal dissection (ESD) for gastric cancer in the remnant stomach poses some specific technical difficulties due to severe fibrosis and the presence of surgical staples. Therefore, we clarified the feasibility and safety of removing staples. Methods We retrospectively analyzed ESD outcomes of cases of gastric cancer in the remnant stomach. Materials This study reviewed 227 patients who underwent ESD for gastric cancer in the remnant stomach or gastric conduit. Patients were divided into those in whom resection extended to the anastomotic site or suture line (AS group; n=90) and those without such extension (non-AS group; n=137). The AS group was further divided into cases in which staples were removed (staple group; n=22) and those in which they were not (control group; n=68). Results The rates of specimen damage and curative resection and the duration and speed of the procedure were significantly worse in the AS group than the non-AS group. There were no significant differences between the staple group and the control group in the curative or complete resection rates, and no complications occurred in the staple group. In a propensity score-matched analysis, the rate of specimen damage was significantly lower in the staple group than in the control group (p=0.002), and the procedure speed tended to be faster (p=0.077). Conclusion Staple removal may improve the outcomes of ESD in patients with gastric cancer in the remnant stomach or gastric conduit by reducing the risk of specimen damage and increasing the procedure speed without complications.

Application of the Falciform Ligament Patch for the Prevention of Duodenal Stump Leakage After Gastrectomy: Technical Report on a Case Series

Background: Duodenal stump leakage (DSL) is a serious complication after gastrectomy. In this study, we developed a novel prevention technique using a falciform ligament patch (FLP) to prevent DSL among high-risk patients after gastrectomy. Materials and Methods: From January 2019 to July 2021, 14 patients who were judged to be at high risk for DSL during preoperative examinations or surgery were included in this retrospective study, and the FLP was applied to the duodenal stump. The falciform ligament was separated from the liver after duodenal transection during gastrectomy; the end part was used to cover the duodenal stump and was fixed using nonabsorbable polypropylene sutures. Results: In total, 14 patients who underwent FLP had one or two risk factors that were identified: 5 patients, gastric cancer duodenal invasion; 4 patients, gastric outlet obstruction (GOO); 1 patient, cancer involving the distal resection margin; 1 patient, duodenal gastrointestinal stromal tumor involving the distal resection margin; 1 patient, gastric cancer duodenal invasion and GOO; and 2 patients, cancer involving the distal resection margin and GOO. FLP construction was successful, and no patient developed complications of DSL. The average hospital stay was 11.9 days, and the patients were discharged without any morbidities after surgery. Conclusions: Therefore, the FLP can be used to prevent DSL among high-risk patients after gastrectomy.

Comparisons of surgical outcomes between robotic and laparoscopic total gastrectomy in patients with clinical stage I/IIA gastric cancer

BACKGROUND

The robotic approach is especially promising for challenging surgeries, such as total gastrectomy. However, it remains unclear whether robotic total gastrectomy (RTG) is superior to conventional laparoscopic total gastrectomy (LTG). The present study aimed to clarify the impact of RTG on short- and long-term outcomes for patients with clinical stage I/IIA gastric cancer.

METHODS

This study included 98 patients with clinical stage I/IIA gastric cancer who underwent minimally invasive total gastrectomy from October 2013 to December 2020 at the Shizuoka Cancer Center. The short- and long-term outcomes of RTG were compared with those of LTG.

RESULTS

This study included 36 RTG and 58 LTG patients. RTG was associated with a significantly longer operative time than LTG (p = 0.023). All complications tended to be lower in the RTG group than in the LTG group (2.8% and 15.5%, respectively; p = 0.083). There were no patients with anastomotic leakage in the RTG group. The multivariate analysis identified LTG as the only independent risk factor for postoperative complications (odds ratio, 6.620; 95% confidence interval, 1.132-126.4; p = 0.034). The survival of the RTG and LTG groups was equivalent.

CONCLUSIONS

RTG reduced the risk of complications compared to LTG. Patients treated using the two approaches showed equivalent survival.

Simultaneous Totally Laparoscopic Distal Gastrectomy and Anterior Resection for Synchronous Gastric and Colon Cancer

Although simultaneous open surgery for synchronous gastric and colon cancer has been reported frequently to date, total laparoscopic resection has been documented rarely. A 63-year-old male patient who presented with complaints of abdominal pain and constipation was diagnosed with synchronous gastric and sigmoid colon cancer. Simultaneous total laparoscopic distal gastrectomy (Roux-en-Y anastomosis and D2 lymph node dissection) and anterior resection were performed with a total of five ports. Total operation time was 310 min. and estimated blood loss was 175 mL. Histopathological examination result was reported as well-differentiated adenocarcinoma for the stomach and moderately differentiated adenocarcinoma for the colon. Staging result was Stage IIA (pT3N0M0, American Joint Committee on Cancer (AJCC) 8th Edition) for both cancers. The patient received postoperative adjuvant chemotherapy. He remains under follow-up at 21 months without any recurrence. With the improved techniques and increased experience in minimally invasive surgery, combined laparoscopic curative resection can be safely performed for gastric and colon cancer.

Propensity-score-matched analysis of a multi-institutional dataset to compare postoperative complications between Billroth I and Roux-en-Y reconstructions after distal gastrectomy

BACKGROUND

Few well-controlled studies have compared postoperative complications between Billroth I (B-I) and Roux-en-Y (R-Y). The aim of the present study was to compare the incidence of overall and severe postoperative complications by reconstruction method after distal gastrectomy.

METHODS

We performed a multi-institutional dataset study of patients who underwent distal gastrectomy with B-I or R-Y reconstruction from 2010 to 2014. Using propensity scores to strictly balance the significant variables, we compared postoperative complications between the techniques.

RESULTS

After matching, we enrolled 1014 patients (n = 507 in each group). The incidence of postoperative complications in the R-Y group was significantly higher vs the B-I group (29% vs 17%, P < 0.0001). The incidence of intra-abdominal abscess (4.3% vs 1.8%, P = 0.0177), bowel obstruction (2.6% vs 0.6%, P = 0.0203), and delayed gastric emptying (5.3% vs 1.0%, P < 0.0001) in the R-Y group was significantly higher vs the B-I group, respectively; we saw no significant difference in leakage (3.4% vs 4.1%, P = 0.5084). The incidence of grade ≥ III severe postoperative complications in the R-Y group was significantly higher vs the B-I group (13% vs 7.1%, P = 0.0013). Multivariable analysis showed that R-Y reconstruction was a strong independent risk factor for overall postoperative complications (odds ratio 1.58, P = 0.0044) and grade ≥ III severe postoperative complications (odds ratio 1.75, P = 0.0127). A forest plot revealed that R-Y reconstruction was associated with a greater risk of both overall and grade ≥ III severe postoperative complications in any subgroups.

CONCLUSIONS

R-Y reconstruction was associated with increasing overall postoperative complications, as well as severe postoperative complications.

Risk Factors for Postoperative Infectious Complications in Elderly Patients with Gastric Cancer

Background

Elderly patients with gastric cancer (GC) are at increased risk of infectious complications following gastrectomy. A limited set of risk factors has been identified to predict complications in these patients. To improve the safety of gastrectomy in this population, we investigated the incidence of infectious complications and associated clinicopathologic, nutritional and surgical risk factors in a cohort of elderly patients with GC.

Methods

Elderly GC patients (≥70 years) who underwent gastrectomy between January 2013 and December 2017 in Peking Union Medical College Hospital were included in the study. Clinicopathologic data were collected retrospectively. Severity of complications was classified using the Clavien–Dindo system. Infectious complications were assessed based on clinical diagnosis of health care-associated infection as defined by the US Centers for Disease Control and Prevention. Multivariate logistic regression analyses were performed to determine the risk factors for infectious complications.

Results

Three hundred thirty-one consecutive patients were included, with a median age of 74 years (range 70–88). The rate of surgical morbidity was 37.5% and the mortality rate was 1.2%. The incidence of infectious complications was 19.6%, with the most common infectious complication being pulmonary infection (11.5%). Preoperative weight loss ≥5% (odds ratio [OR] = 2.21; 95% CI, 1.15–4.28; p = 0.018), Charlson comorbidity index score ≥3 (OR = 2.83; 95% CI, 1.30–6.16; p = 0.009) and preoperative hsCRP level ≥10 mg/L (OR = 2.48; 95% CI, 1.14–5.38; p = 0.022) were independently associated with infectious complications.

Conclusion

Preoperative weight loss, elevated hsCRP level and comorbidity burden can be used to predict postoperative infectious complications in elderly GC patients. It is recommended to pay more attention to the treatment of elderly GC patients with these risk factors.

Risk Factors for Duodenal Stump Leakage after Laparoscopic Gastrectomy for Gastric Cancer

Purpose

Duodenal stump leakage (DSL) is a potentially fatal complication that can occur after gastrectomy, but its underlying risk factors are unclear. This study aimed to investigate the risk factors and management of DSL after laparoscopic radical gastrectomy for gastric cancer (GC).

Materials and Methods

Relevant data were collected from several prospective databases to retrospectively analyze the data of GC patients who underwent Billroth II (B-II) or Roux-en-Y (R-Y) reconstruction after laparoscopic gastrectomy from 2 institutions (Sir Run Run Shaw Hospital, Zhejiang University School of Medicine, and HwaMei Hospital, University of Chinese Academy of Sciences). The DSL risk factors were analyzed using univariate and multivariate analysis regression.

Results

A total of 810 patients were eligible for our analysis (426 with R-Y, 384 with B-II with Braun). Eleven patients had DSL (1.36%). Body mass index (BMI), elevated preoperative C-reactive protein (CRP) level, and unreinforced duodenal stump were the independent risk factors for DSL. DSL was diagnosed in 2–12 days, with a median of 8 days. Seven patients received conservative treatment, 3 patients received puncture treatment, and only 1 patient required reoperation. All patients recovered successfully after treatment.

Conclusions

The risk factors of DSL were BMI ≥24 kg/m², elevated preoperative CRP level, and unreinforced duodenal stump. Nonsurgical treatments for DSL are preferred.

Single Purse-String Suture for Reinforcement of Duodenal Stump During Laparoscopic Radical Gastrectomy for Gastric Cancer

Background: Duodenal stump leakage (DSL) is a serious surgical complication after radical gastrectomy with Roux-en-Y or BillrothII reconstruction. This study was designed to evaluate the effectiveness of laparoscopic single purse-string suture for reinforcement of duodenal stump.

Methods: A total of 183 patients harboring gastric adenocarcinoma following laparoscopic radical gastrectomy with Roux-en-Y or BillrothIIreconstruction and single purse-string suture for reinforcement of duodenal stump were retrospectively enrolled from Zhongshan Hospital of Fudan University (Shanghai, China) between January 2014 and December 2016. Operative variables and short-term complications were documented and analyzed. Clavien-Dindo classification system was used to identify surgical complications.

Results: Among 183 patients, 108 (59.02%) patients received distal gastrectomy and 75 (40.98%) received total gastrectomy. 88 (48.09%) patients underwent Roux-en-Y reconstruction and 95 (51.91%) patients underwent Billroth-II reconstruction. The mean time of laparoscopic single purse-string suture was 5.01 ± 1.33 min (range from 3.6 to 10.2 min). Postoperative early complication occurred in 26 cases of the patients. There were 4 cases of system-related complications (2.19%), including 3 cases of pulmonary infection (1.64%) and 1 cases of cardiovascular event (0.55%); and 22 cases of surgery-related complications (12.02%), including 6 cases of intra-abdominal infection (3.28%), 4 cases of pancreatic leakage (2.19%), 4 cases of wound complications (2.19%), 3 cases of gastroparesis (1.64%), 2 cases of intra-abdominal bleeding (1.09%), 2 cases of ileus (1.09%), 1 cases of lymphatic leakage (0.55%), and no duodenal stump leakage.

Conclusion: Reinforcement on duodenal stump using laparoscopic single purse-string suture during laparoscopic radical gastrectomy is simple and effective and could avoid the incidence of duodenal stump leakage to some extent.

Systematic assessment of complications after robotic-assisted total versus distal gastrectomy for advanced gastric cancer: A retrospective propensity score-matched study using Clavien-Dindo classification

BACKGROUND

Despite increasing evidence demonstrated robot-assisted distal gastrectomy (RADG) is safe and feasible for the treatment of advanced gastric cancer (AGC), robot-assisted total gastrectomy (RATG) remains a challenging procedure due to its technical difficulties and possible postoperative complications (POCs). This study aimed to systematically evaluate POCs following RATG.

METHODS

Between January 2017 and January 2019, 319 AGC patients with pathological stage T2-4aN0-3M0 who underwent RADG or RATG were enrolled. POCs were stratified using the Clavien-Dindo classification. One-to-one propensity score matching was performed to reduce confounding differences.

RESULTS

After matching, 266 patients met the criteria for further analysis. Ultimately, 64 patients (24.1%) who developed POCs had 126 clinical manifestation events. Overall the POCs rate was significantly greater after RATG in comparison with RADG (29.3% vs. 18.8%; P = 0.045), and more major POCs (Clavien-Dindo grade ≥ IIIa) were observed in the RATG group (14.3% vs. 5.3%; P = 0.013). The POCs were then classified into local and systemic POCs. The rates of local POCs (35.3% vs. 19.5%; P = 0.004) and systemic POCs (24.8% vs. 15.0%; P = 0.046) were significantly higher in the RATG group than the RADG group. Subgroup analysis showed that the anastomotic leakage rate was higher after RATG (5.3% vs. 0.8%; P = 0.031), whereas the remaining POCs were similar between the two groups. Patients with higher POCs significantly had longer postoperative length of stay (R = 0.895, P = 0.003). Multivariate analysis confirmed age, extent of resection, and TNM stage were risk factors for all POCs.

CONCLUSIONS

These findings demonstrated that RATG is technically feasible and safe for treatment of AGC with acceptable morbidity and mortality rates. The POCs rate of RATG was higher than RADG, especially for anastomotic leakage. More effective anastomotic techniques are needed in RATG to prevent leakage.
