Postoperative morbidity and quality of life between totally laparoscopic total gastrectomy and laparoscopy-assisted total gastrectomy: a propensity-score matched analysis
BMC Cancer volume 21, Article number: 1016 (2021)
This study aimed to evaluate the surgical outcome and quality of life (QoL) of totally laparoscopic total gastrectomy (TLTG) compared with laparoscopy-assisted total gastrectomy (LATG) in patients with clinical stage I gastric cancer.
From 2012 to 2018, EGC patients who underwent TLTG (n = 223), including the first case with intracorporeal hemi-double stapling, were matched to those who underwent LATG (n = 114) with extracorporeal circular stapling, using 2:1 propensity score matching (PSM). Prospectively collected morbidity was compared between the TLTG and LATG groups in conjunction with the learning curve. The European Organization for Research and Treatment of Cancer (EORTC) QoL questionnaires QLQ-C30, STO22, and OG25 were prospectively surveyed during postoperative 1 year for patient subgroups.
After PSM, grade I pulmonary complication rate was lower in the TLTG group (n = 213) than in the LATG group (n = 111) (0.5% vs. 5.4%, P = 0.007). Other complications were not different between the groups. The learning curve of TLTG was overcome at the 26th case in terms of the comprehensive complication index. The TLTG group after learning curve showed lower grade I pulmonary complication rate than the matched LATG group (0.5% vs. 4.7%, P = 0.024). Regarding postoperative QoL, the TLTG group (n = 63) revealed less dysphagia (P = 0.028), pain (P = 0.028), eating restriction (P = 0.006), eating (P = 0.004), odynophagia (P = 0.023) than the LATG group (n = 21). Multivariate analyses for each QoL item demonstrated that TLTG was the only common independent factor for better QoL.
TLTG reduced grade I pulmonary complications and provided better QoL in dysphagia, pain, eating, odynophagia than LATG for patients with clinical stage I gastric cancer.
The Korean national cancer screening program contributed to an increase in the diagnosis of early gastric cancer (EGC), reaching 61% in 2014. In particular, the incidence of upper one-third EGC gradually increased from 11.2% in 1995 to 16.0% in 2014, according to the A Information Committee of Korean Gastric Cancer [1, 2] The global incidence of cardia cancer has also grown seven-fold over the past decades . In the era of minimally invasive surgery, laparoscopy-assisted total gastrectomy (LATG) or totally laparoscopic total gastrectomy (TLTG) have been highlighted with the expectation of minimal invasiveness. TLTG has not been fully standardized yet due to the technical difficulty of intracorporeal esophagojejunostomy. Even a recent large prospective multicenter phase II trial (KLASS-03) reported acceptable postoperative morbidity and mortality for patients with clinical stage I gastric cancer, the procedures for esophagojejunostomies were not standardized yet .
Previous studies using those various surgical procedures reported the potential advantages of TLTG, such as less pain, less blood loss, and shorter operation time, than LATG [5,6,7,8,9,10]. Besides, upper abdominal pain interferes with diaphragmatic movement and subsequently worsens pulmonary complications, which can be the typical morbidity after TLTG or LATG [11,12,13]. However, level I evidence for these morbidities has not been established by a randomized critical trial yet, and a reasonable case matching study with a sufficient sample size also has not even been reported. On the other hand, evaluating the postoperative quality of life (QoL) may provide meaningful implications for minimally invasive surgery. Less adhesion after laparoscopic gastrointestinal surgery was reported to improve QoL such as global health status, reflux symptom, and appetite loss by enabling a comfortable diet with less pain and better peristalsis [14,15,16,17]. However, QoL after TLTG was rarely compared with that after LATG, especially at multiple time points after surgery .
This study aimed to evaluate and compare surgical outcomes and QoL of TLTG with those of LATG in patients with clinical stage I gastric cancer using propensity-score matching (PSM).
Materials and methods
We reviewed the prospectively collected morbidity database of consecutive patients who underwent TLTG for clinical stage I gastric cancer between 2012 and 2018 at Seoul National University Hospital (SNUH). Clinical staging was evaluated by preoperative esophagogastroduodenoscopy, endoscopic ultrasonography and computed tomography. In this study, TLTG was defined as the case in which esophagojejunostomy was reconstructed intracorporeally, irrespective of intra- or extracorporeal jejunostomy. In SNUH, TLTG was performed since 2013, and four surgeons have gradually adopted TLTG according to the trend of minimal invasiveness demand, rather than separate indications for TLTG or LATG (Supplementary Fig. S1). All TLTG cases, including the first starting case with intracorporeal esophagojejunostomy by using the hemi-double stapling technique (hDST) were enrolled in this study to elucidate the safe adoption of new laparoscopic surgical skill and minimize the selection bias. TLTGs with intracorporeal esophagojejunostomy other than hDST or reduced port laparoscopic total gastrectomies were excluded (Supplementary Fig. S2).
Clinicopathologic data and other operative parameters were retrospectively reviewed. Each case from the TLTG group was 2:1 propensity score matched to control cases of the LATG group. The matching variables included age, sex, body mass index (BMI), combined organ resection, and pathological T and N stages. A propensity score of each patient was estimated by logistic regression (SPSS version 25; IBM Inc., Chicago, IL, USA) and matched nearest-neighbor value within a caliper 0.02 times the standard deviation of the estimated score. After PSM, the balance of covariates between TLTG and LATG group were evaluated by calculating the standardized mean difference. Detailed method for statistical analysis was described in supplementary methods.
For TLTG, a 3–4 cm laparotomy was made in the umbilicus or through the left lower port site after transecting the duodenum. The anvil head of the circular stapler (EEA, 25–4.8 mm, Covidien, Mansfield, MA, USA), with its rod knotted several times using a 2–0 Prolene, were brought into the peritoneal cavity. The distal esophagus was fastened tightly with umbilical tape (32 mm width, 15 cm length, Ethicon, USA) and stretched in the direction of left lower quadrant. Then, the anterior wall of the distal esophagus was opened along the circumferential direction. The prepared anvil was inserted through the esophagotomy site and advanced into the esophagus higher than the expected proximal resection margin. By piercing the needle through the medial side of the esophageal wall, a spike of the anvil rod could be retrieved outside. The esophagus was transected by the linear stapler with 60-mm AMT, a purple cartridge (Endo GIA™, Covidien, Mansfield, MA, USA) above the esophagotomy site. As a result, the anvil rod is located at the medial end of the staple line (Fig. 1).
After the resected stomach was brought out through the mini-laparotomy, side-to side jejuno-jejunostomy was performed at approximately 40 cm distal to the expected esophagojejunostomy site using the linear stapler with 45- or 60-mm AVM, tan cartridge (Endo GIATM, Covidien). The circular stapler was inserted into the jejunal Roux limb, fastened with a rubber band to prevent slippage. Then, the Roux limb with the circular stapler was brought into the abdominal cavity, and pneumoperitoneum was reestablished. Under a secure laparoscopic view, the jejunal Roux limb was connected to the anvil, and intracorporeal anastomosis was finally performed. The jejunal stump was closed by the linear stapler with 60-mm AVM, a tan cartridge.
For LATG, about 8.5 cm sized upper midline incision was made at the epigastrium . Under the direct vision through the mini-laparotomy, a purse-string suture and device were applied to the distal esophagus, and the stomach was transected distal to the purse-string device. The anvil head of the circular stapler (EEA, 25–4.8 mm, Covidien, Mansfield, MA, USA) was inserted into the esophagus and the purse-string suture was secured to fasten the anvil rod. Then, the extracorporeal esophagojejunsotomy was performed with a 25 mm circular stapler through a mini-laparotomy incision. Extracorporeal side to side jejuno-jejunostomy was performed through the mini-laparotomy incision with a similar manner to jejuno-jejunostomy in TLTG.
Surgical outcome and quality of life
Complication data have been prospectively collected and recorded with the consensus of the entire gastrointestinal surgical team of SNUH through the weekly conference. General postoperative management including oral care, usage of prophylactic antibiotics, and pulmonary rehabilitation was the same over the study period. Morbidity and mortality were evaluated according to the Clavien-Dindo classification, and comprehensive complication index (CCI) calculated by the CCI formula (https://www.assessurgery.com/) . Detailed methods for determining the learning curve based on cumulative sum score and evaluating the quality of life were described in supplementary methods.
Before matching, the TLTG group (n = 223) and LATG group (n = 114) had no significant differences in baseline clinicopathologic variables (Table 1). After 2:1 PSM, the 213 patients in the TLTG group were matched to the 111 patients in the LATG group. The propensity scores, matching variables, and other remaining variables became highly balanced between TLTG and LATG groups (Supplementary Fig. S3). In terms of oncological safety, the number of retrieved lymph nodes and the distribution of TNM stage was not significantly different between TLTG and LATG (Table 1). In addition, the number of retrieved lymph nodes per each station was not significantly different across all stations between TLTG and LATG (Supplementary Fig. S4).
Regarding surgical complications within postoperative 1 month, grade I pulmonary complications of the TLTG group were significantly lower than those of the LATG group before (0.9% vs. 5.3%, P = 0.020) and after matching (0.5% vs. 5.4%, P = 0.007). However, the overall rate of pulmonary complications was not different between two groups before (10.8% vs. 12.3%, p = 0.717) and after matching (9.4% vs. 12.6%, p = 0.445). The other complications, including anastomosis-related complications, were not significantly different between the two groups before or after matching. Regarding complications detected between the postoperative 1 month and 1 year, the incidence and detection date of delayed stenosis of esophagojejunostomy were not different between the two groups before and after matching (Table 2). Feeding jejunostomy was not conducted in all cases of both TLTG and LATG groups.
Learning curve for TLTG
The CUSUM graph using the CCI showed two negatively sloping curve during the observation period with the trend line (y = − 0.3118x + 55.602) (Supplementary Fig. S5a). In the first phase, the CUSUM score gradually increased and reached the first highest peak at case 26 (score, 118.00), then two more peak values at case 50 (score, 113.77) and case 73 (score, 80.77), and decreased until case 103 (score, − 112.357). The TLTG group did not show clear decreasing pattern in operation time over chronological cases (Supplementary Fig. S5b). We defined the 26th case as a point of overcoming the learning curve, and rationales for this was described in Supplementary Table 1.
Table 3 presents the postoperative morbidity between the late TLTG group after overcoming the learning curve and the re-matched LATG group since 2012 when LATG was actively performed. The overall rate of grade I complication (2.1% vs 8.5%, P = 0.016), especially pulmonary complication (0.5% vs. 4.7%, P = 0.024), was still significantly lower in the late TLTG group than in the LATG group after matching. The overall rate of pulmonary complications was not different between two late groups (9.0% vs. 11.3%, P = 0.546). Other complications, including anastomosis-related complications, were not different between the late TLTG and LATG groups before and after matching.
Quality of life
The TLTG (n = 63) and LATG (n = 21) groups were matched to prospectively collected QoL data. The clinicopathologic characteristics and complications were not different between the two groups (Supplementary Table 2). During postoperative 1 year, the rates of STO22 dysphagia (P = 0.028), STO22 pain (P = 0.028), STO22 eating restriction (P = 0.006), OG25 eating (P = 0.004), and OG25 odynophagia (P = 0.023) were significantly lower in the TLTG group (n = 63) than in the LATG group (n = 21) (Fig. 2a-e). Other QoL items of EORTC-C30, STO22, and OG25 questionnaires between the TLTG and LATG groups are presented in Supplementary Fig. S6. For those five significant QoL questionnaires, ANCOVA at each three different time points (postoperative 3 months, 6 months, and 1 year) revealed that STO22 dysphagia at postoperative 6 months (15.55 vs. 31.26, P < 0.001), STO22 pain at postoperative 3, 6 and 12 months (20.64 vs. 34.51, P = 0.031; 19.15 vs. 32.09, P = 0.006; 18.82 vs. 30.15, P = 0.002), STO22 eating restriction at postoperative 6 months (20.50 vs. 30.61, P = 0.031), OG25 eating at postoperative 6 and 12 months (20.08 vs. 28.73, P = 0.007; 20.75 vs. 37.18, P = 0.012), and OG25 odynophagia at postoperative 6 months (13.82 vs. 28.82, P = 0.003) were significantly better in the TLTG group than in LATG group, after controlling the confounding effects of preoperative QoL. Multivariate linear regression for variables including age, sex, BMI, TLTG (vs. LATG), pT stage, pN stage, baseline QoL score, and the rate of overall complication (CCI) revealed that TLTG was the only common independent risk factor for significantly better QoL at each different time point, after excluding all possible confounding factors (all P < 0.05) (Table 4). For more robust validation of the role of TLTG, we used the anastomosis related complication and motility disorder as covariates for multivariate analysis, instead of CCI as overall complications. Still, TLTG remained as the only common independent risk factor for better QoL (Supplementary Table 3).
This study successfully demonstrated the advantage of TLTG compared with matched LATG in terms of lower grade I pulmonary complication rate and better QoL of dysphagia, pain, or eating during postoperative 1 year. Retrospective studies cannot usually be sensitive enough to analyze parameters such as minor complications or changes in QoL and may provide false-negative or biased results. This study utilized prospectively collected complication data and QoL cohort, both of which had been recruited independently of the original purpose of this study. We believe that our study can provide less biased and more sensitive results than other unmatched retrospective studies.
The postoperative pulmonary complication was reported as one of the greatest risk factors for postoperative mortality in gastric cancer patients [12, 23, 24]. In addition, total gastrectomy was an independent risk factor for pulmonary complications following laparoscopic gastrectomy . Previous meta-analysis comparing LATG with open TG reported that LATG was associated with a significant reduction in medical complications, but a contribution from respiratory complications was not significant . Other retrospective study limitedly demonstrated the lower incidence of pulmonary complications in the LATG group than in the OTG group, only in patients aged over 65 . On the other hand, previous studies comparing TLTG and LATG mainly focused on anastomotic complications, and rarely addressed issues with pulmonary complications [1,2,3,4,5]. Upper abdominal incision causes decreased pulmonary function more frequently than lower abdominal surgery [11, 27, 28]. The mini-laparotomy wounds of the LATG are inevitably larger and located closer to epigastrium than those of TLTG. In addition, the LATG group had a higher score of STO22 pain than the TLTG group (Fig. 2b). The larger incisions in the epigastrium and worse pain score may explain the limited movement of the diaphragm and deep breathing, followed by a decreased pulmonary function in the LATG group. In this study, underlying pulmonary disease was not significantly different between TLTG and LATG groups, and the number of high Charlson comorbidity index (≥3) was limited in both groups (Table 1), which could be one explanation of limited difference in low grade pulmonary complication only. Considering the possible risk of atelectasis to serious respiratory failure especially in underlying comorbid patients [29, 30], TLTG can be more meaningful in patients with underlying pulmonary disease.
This is the first study comparing QoL over consecutive multiple time points during the year after operation between TLTG and LATG groups. Previous studies reported better QoL scores of C30 pain and STO22 dysphagia in the TLTG group than in the LATG group, but only investigated the QoL at a single time point and did not include OG25, more sensitive in evaluating QoL after total gastrectomy [18, 31]. The changes of QoL associated with surgical procedures were mainly determined during the early recovery period . Most acute changes of postoperative QoL gradually became stable during the first year following surgery [33, 34], and tend to be recovered close to preoperative QoL in about 1 year after gastrectomy . Based on those previous studies, our QoL cohort followed up 1 year after gastrectomy. Instead, we focused on consecutive multiple time points during that first year after gastrectomy between two groups. In addition to acute change and recovery of QOL after surgery, long term changes of QOL due to gastrointestinal adaption could be further investigated in the future.
In this study, TLTG only determined a better QoL for dysphagia, eating, or odynophagia. DST without purse-string suture was first introduced in 1994 as an easier alternative technique to single stapling technique (SST), but has a risk of high postoperative anastomotic stenosis rate [35, 36]. To overcome this limitation, hDST was proposed, but previous studies still reported high rates of stenosis (7.3–21%) and leakage (4.9–9.9%) [35, 37, 38]. Since 2013, SNUH started TLTG with intracorporeal hDST using needle-guided anvil fixation. Our institution standardized this technique with repeated discussion and consensus among surgeons from the first case, by which all complications were not different among operators (P = 0.947, supplementary Table 4). Many previous reports of hDST techniques revealed that it was difficult to tighten the entry hole of the anvil spike at the esophageal stump [37, 38]. On the other hand, the anvil spike located in the middle of the esophageal wall still might have a risk of double stapling across the efferent loop of the Roux limb . As a simple modification, we pulled out the anvil in the medial esophageal wall using the guiding thread, which led to the smallest entry hole for the anvil spike, and secured hDST with a single stapling site completely toward the efferent loop and double stapling site toward the blind loop of the jejunal Roux-limb. The low rates of early and delayed anastomotic complications demonstrated the safety and efficacy of our modified hDST. In the current study, 25 mm circular stapler was routinely used for esophagojejunostomy. Although circular stapler with 28 or 29 mm might be considered to minimize stenosis of esophagojejunostomy, previous nationwide phase II clinical trial for laparoscopic total gastrectomy revealed that ninety-eight patients who underwent laparoscopic total gastrectomy with a 25 mm circular stapler presented no stenosis . On the other hand, it would be often very difficult to insert the shaft of a 28/29 mm circular stapler into jejunal lumen because of its large diameter, and may increase the risk of anastomotic failure.
In addition, the TLTG group with hDST showed better QoL of dysphagia and eating restriction than the LATG group. Adhesion after initial abdominal surgery occurs within the postoperative 1 year and may last for several years [40,41,42,43].. Adhesion tissue were reported to contain nerve conducting pain stimuli . Since, fixed adhesion can compromise the lumen of bowel, and filmy adhesion allowing movement between the bowel and surrounding structure can elicit nonobstructive abdominal pain, patients with peritoneal adhesion can manifest vague to highly distressing pain . The unpredictability of abdominal pain caused by adhesions significantly impacts on a patient’s emotions and social life, including fear for eating . We assume that less exposure of the peritoneal cavity, especially the upper abdomen, may induce less adhesion around the anastomosis or provide better recovery of bowel movement [47,48,49]. Taken together, not only the possible different exposure of peritoneal cavity but also the different anastomotic technique may explain the different QoL in this study.
In this study, we analyzed the CUSUM and learning curve based on the CCI, rather than operation time. In the past, standardizing multiple complications into a single variable seemed impossible due to the absence of adequate methods. However, through introducing CCI, one representative complication index per patient can be estimated. To our knowledge, this is the first study to evaluate the learning curve using CCI. Because CCI is directly related to the patient’s outcome, this approach to the learning curve is more reasonable and intuitively understandable, than previous ones based on operation time. Our study can imply that simple effort to shorten the operation time may be less meaningful during the adoption and stabilization of a novel and complex surgical technique.
This study has some limitations. Firstly, since LATG and TLTG were performed in different time periods, there might be a discrepancy in laparoscopic surgical skills or chronologic changes in clinicopathologic factors between the TLTG and LATG groups. This time trend was inevitable when comparing old and new surgical techniques in retrospective analysis. To minimize this bias, we included all patients in the TLTG group from the first case, and all patients in the LATG group during the same period of TLTG for analysis. Besides, all surgeons at SNUH started performing TLTG in a similar period. Secondly, the sample size for QoL evaluation between TLTG and LATG was limited. In SNUH, an independent prospective cohort study was conducted to analyze only QoL of patients with gastrectomy, regardless of the purpose of the present study. When the current study was designed, the QoL survey for the independent prospective trial were already completed. Totally 84 patients in the current study had pertained QoL data recorded from an independent QoL cohort, and selection process were not based on specific criteria or intentions. Therefore, the independence of QoL data can be the unbiased evidence for current study. Despite the small sample size of QoL data, this is the first study comparing QoL over consecutive multiple time points during the year after operation between TLTG and LATG groups. Considering that a small sample size usually has a risk of yielding false-negative or low sensitivity results, the significant difference in QoL between TLTG and LATG, even in the multivariate analysis, still can be valuable. However, large-scale prospective RCTs are necessary to validate more robust evidence for QoL differences. Thirdly, this study did not include the linear stapling technique for both TLTG and LATG. Previous studies reported a tendency of wider lumen and less stenotic event in linear stapling technique than in circular stapling . One recent study based on PSM analysis revealed that overall postoperative complications including stenotic event in esophagojejunostomy was not different between the two groups . Since our modified hDST also demonstrated the low rate of stenotic complications, prospective randomized clinical trial between the circular stapling including our modified hDST and the linear stapling technique would be expected to provide valuable evidence in the future.
In conclusion, TLTG with hDST were associated with reduced grade I pulmonary complications and better QoL in terms of dysphagia, pain, eating, and odynophagia than LATG for patients with clinical stage I gastric cancer.
