Postoperative quality of life after laparoscopy-assisted pylorus-preserving gastrectomy compared with laparoscopy-assisted distal gastrectomy for early gastric cancer

Quality of Life Following the Surgical Management of Gastric Cancer Using Patient-Reported Outcomes: A Systematic Review

Introduction: Surgical management of gastric adenocarcinoma can have a drastic impact on a patient's quality of life (QoL). There is high variability among surgeons' preferences for the type of resection and reconstructive method. Peri-operative and cancer-specific outcomes remain equivalent between the different approaches. Therefore, postoperative quality of life can be viewed as a deciding factor for the surgical approach. The goal of this study was to interrogate patient QoL using patient-reported outcomes (PROs) following gastrectomy for gastric cancer. Methods: This systematic review was registered at Prospero and followed PRISMA guidelines. Medline, Embase, and Scopus were used to perform a literature search on 18 January 2020. A set of selection criteria and the data extraction sheet were predefined. Covidence (Melbourne, Australia) software was used; two reviewers (P.C.V. and E.J.) independently reviewed the articles, and a third resolved conflicts (A.B.F.). Results: The search yielded 1446 studies; 308 articles underwent full-text review. Ultimately, 28 studies were included for qualitative analysis, including 4630 patients. Significant heterogeneity existed between the studies. Geography was predominately East Asian (22/28 articles). While all aspects of quality of life were found to be affected by a gastrectomy, most functional or symptom-specific measures reached baseline by 6-12 months. The most significant ongoing symptoms were reflux, diarrhoea, and nausea/vomiting. Discussion: Generally, patients who undergo a gastrectomy return to baseline QoL by one year, regardless of the type of surgery or reconstruction. A subtotal distal gastrectomy is preferred when proper oncologic margins can be obtained. Additionally, no one form of reconstruction following gastrectomy is statistically preferred over another. However, for subtotal distal gastrectomy, there was a trend toward Roux-en-Y reconstruction as superior to abating reflux.

Effect of preoperative colonoscopy combined with preservation of the right vein of the gastric omentum during radical resection of intestinal cancer on the efficacy and prognostic indicators of the procedure

BACKGROUND

The aim of this study was to investigate the clinical value of preoperative colonoscopy combined with right gastroepiploic vein preservation (RGV) in radical resection of colorectal cancer for right colon cancer.

METHODS

A total of 120 patients with right colon cancer in our hospital from February 2019 to October 2021 were selected and randomly divided into study group (RGV preserved during operation) and control group (RGV not preserved during operation), with 60 cases in each group. Perioperative parameters, intestinal fatty acid binding protein (I-FABP), Pittsburgh Sleep Quality Index (PSQI), total protein (TP), D-lactate (D-LA), quality of life scale (SF-36) scores, incidence of complications, and tumor recurrence rate were compared between the two groups.

RESULTS

Duration of hospitalization was shorter in the study group than in the control group (P<0.05). Six months after surgery, I-FABP, D-LA levels and PSQI scores were lower, and TP levels and SF-36 scores were higher in the study group than in the control group (P<0.05). The incidence of complications in the study group (11.67% vs. 33.33%) was lower than that in the control group (P<0.05). There was no significant difference in tumor recurrence rate 6 months after operation between the two groups (P>0.05).

CONCLUSIONS

Preoperative colonoscopy combined with RGV preservation in radical resection of colorectal cancer for right colon cancer can avoid surgical trauma caused by unnecessary transection, reduce gastrointestinal function damage, promote physical rehabilitation and shorten hospital stay, and reduce the risk of complications such as gastroparesis.

Patient-Reported Outcomes of Individuals with Gastric Cancer Undergoing Totally Laparoscopic Versus Laparoscopic-Assisted Total Gastrectomy: A Real-World, Propensity Score-Matching Analysis

OBJECTIVE

Totally laparoscopic total gastrectomy (TLTG) and laparoscopic-assisted total gastrectomy (LATG) are two types of minimally invasive radical gastrectomy procedures to treat gastric cancer (GC). This study compared the long-term prognosis and postoperative health-related quality of life (HRQoL) between TLTG and LATG.

METHODS

A total of 106 patients who underwent TLTG and 1,076 patients who underwent LATG at the Union Hospital of Fujian Medical University (Fuzhou, China) between January 2014 and April 2018 were included in the propensity score matching (PSM, 1:2). Patient-reported outcomes at 3, 6, and 12 months after gastrectomy were analyzed. The questionnaire referred to the European Organization for Research and Treatment of Cancer (EORTC) 30-item core QoL (QLQ-C30)and the GC module (QLQ-STO22) questionnaire.

RESULTS

After PSM, there were no significant differences in clinicopathological characteristics between the TLTG (n = 104) and the LATG groups (n = 208). Operative time and volume of blood loss were significantly lower in the TLTG group than in the LATG group. Kaplan-Meier survival analysis revealed similar 3-year survival rates between the TLTG and LATG groups (83.7 vs. 80.3%, respectively; P = 0.462). Tolerance to nonliquid diet, decrease in body weight, and albumin levels were also significantly lower in the TLTG group than in the LATG group (all P < 0.05). The HRQoL scale demonstrated that the overall score in the TLTG group was better than that in the LATG group at 3, 6, and 12 months after gastrectomy (all P < 0.05).

CONCLUSIONS

Patients with GC undergoing TLTG reported better HRQoL and experienced faster recovery of social function than those undergoing LATG, although the two groups demonstrated similar short-term outcomes and long-term prognosis.

Effects of robotic and laparoscopic-assisted surgery on lymph node dissection and quality of life in the upper third of gastric cancer: A retrospective cohort study based on propensity score matching

Objective

The objective of this study was compare the effects of robot-assisted and laparoscopic-assisted surgery on lymph node dissection and quality of life in upper third gastric cancer patients undergoing radical total gastrectomy.

Methods

The clinical and follow-up data of 409 patients with upper third gastric cancer who underwent total gastrectomy from July 2016 to May 2021 were enrolled. The patients were divided into a robotic group (n = 106) and a laparoscopic group (n = 303). Age, sex, body mass index, American Society of Anesthesiologists score, tumor size and location, pathological type, cT, cN, and cTNM were adjusted to offset selection bias. The patient characteristics, operative procedures, surgical outcomes, oncologic and pathologic outcomes, number of lymph node dissections, quality of life assessment, and nutritional status were compared between the two groups.

Results

After propensity score matching, 61 cases were included in the robotic group and 122 cases were included in the laparoscopic group. The number of dissected lymph nodes (37.3 ± 13.5 vs. 32.8 ± 11.8, P = 0.022) significantly differed between the two groups. The number of lower mediastinal and subphrenic lymph nodes in the robotic group was greater than that in the laparoscopic group, and the difference was statistically significant (P < 0.001). Compared with the laparoscopic group, the total score of physical symptoms in the robotic group was significantly lower at 6 and 12 months after surgery (P = 0.03 and P = 0.001, respectively). The total social function score at 6 and 12 months after surgery was higher in the robotic group (P = 0.006 and P = 0.022). The quality of life scores were statistically significant only at 3 months after the operation (P = 0.047). A higher patient-generated subjective global assessment (PG-SGA) score is when the score significantly correlated (P < 0.001) with a higher related physical symptoms score, lower social function score, and lower quality of life score.

Conclusion

Compared with laparoscopic radical gastrectomy, robotic radical gastrectomy is safe and feasible. Compared with laparoscopic radical gastrectomy, robotic radical gastrectomy was more refined, was associated with less surgical bleeding, and increased the quality of lymph node dissection. In addition, patients in the robotic group showed better postoperative quality of life.

Korean Practice Guidelines for Gastric Cancer 2022: An Evidence-based, Multidisciplinary Approach

Gastric cancer is one of the most common cancers in Korea and the world. Since 2004, this is the 4th gastric cancer guideline published in Korea which is the revised version of previous evidence-based approach in 2018. Current guideline is a collaborative work of the interdisciplinary working group including experts in the field of gastric surgery, gastroenterology, endoscopy, medical oncology, abdominal radiology, pathology, nuclear medicine, radiation oncology and guideline development methodology. Total of 33 key questions were updated or proposed after a collaborative review by the working group and 40 statements were developed according to the systematic review using the MEDLINE, Embase, Cochrane Library and KoreaMed database. The level of evidence and the grading of recommendations were categorized according to the Grading of Recommendations, Assessment, Development and Evaluation proposition. Evidence level, benefit, harm, and clinical applicability was considered as the significant factors for recommendation. The working group reviewed recommendations and discussed for consensus. In the earlier part, general consideration discusses screening, diagnosis and staging of endoscopy, pathology, radiology, and nuclear medicine. Flowchart is depicted with statements which is supported by meta-analysis and references. Since clinical trial and systematic review was not suitable for postoperative oncologic and nutritional follow-up, working group agreed to conduct a nationwide survey investigating the clinical practice of all tertiary or general hospitals in Korea. The purpose of this survey was to provide baseline information on follow up. Herein we present a multidisciplinary-evidence based gastric cancer guideline.

Pathological and oncological outcomes of pylorus-preserving versus conventional distal gastrectomy in early gastric cancer: a systematic review and meta-analysis

Background

Pylorus-preserving gastrectomy (PPG) is a function-preserving surgery for the treatment of early gastric cancer (EGC) in the middle third of the stomach. According to the literature reports, PPG decreases the incidence of dumping syndrome, bile reflux, gallstone formation, and nutritional deficit compared with conventional distal gastrectomy (CDG). However, the debates about PPG have been dominated by the incomplete lymphadenectomy and oncological safety. We carried out a systematic review and meta-analysis to evaluate the pathological and oncological outcomes of PPG.

Methods

The protocol was registered in PROSPERO under number CRD42022304677. Databases including PubMed, Embase, Web of Science, and the Cochrane Register of Controlled Trials were searched before February 21, 2022. The outcomes included the pooled odds ratios (ORs) for dichotomous variables and weighted mean differences (WMDs) for continuous variables. For all outcomes, 95% confidence intervals (CIs) were calculated. Meta-analysis was performed using STATA software (Stata 14, Stata Corporation, Texas) and Review Manager 5.4.

Results

A total of 4500 patients from 16 studies were included. Compared with the CDG group, the PPG group had fewer lymph nodes harvested (WMD= −3.09; 95% CI −4.75 to −1.43; P < 0.001). Differences in the number of resected lymph nodes were observed at stations No. 5, No. 6, No. 9, and No. 11p. There were no differences in lymph node metastasis at each station. Shorter proximal resection margins (WMD = −0.554; 95% CI −0.999 to −0.108; P = 0.015) and distal resection margins (WMD = −1.569; 95% CI −3.132 to −0.007; P = 0.049) were observed in the PPG group. There were no significant differences in pathological T1a stage (OR = 0.99; 95% CI 0.80 to 1.23; P = 0.88), T1b stage (OR = 1.01; 95% CI 0.81 to 1.26; P = 0.88), N0 stage (OR = 0.97; 95% CI 0.63 to 1.48; P = 0.88), tumor size (WMD = −0.10; 95% CI −0.25 to 0.05; P = 0.187), differentiated carcinoma (OR = 1.04; 95% CI 0.74 to 1.47; P = 0.812) or signet ring cell carcinoma (OR = 1.22; 95% CI 0.90 to 1.64; P = 0.198). No significant differences were observed between the groups in terms of overall survival (HR = 0.63; 95% CI 0.24 to 1.67; P = 0.852) or recurrence-free survival (HR = 0.29; 95% CI 0.03 to 2.67; P = 0.900).

Conclusions

The meta-analysis of existing evidence demonstrated that the survival outcomes of PPG may be comparable to those of CDG. However, fewer lymph nodes at stations in No. 5, No. 6, No. 9, and No. 11p were harvested with PPG. We also found shorter proximal resection margins and distal resection margins for PPG, meaning more remnant stomachs would be preserved in PPG.

Meta-Analysis of the Effects of Three-Dimensional Visualized Medical Techniques Hepatectomy for Liver Cancer with and without the Treatment of Sorafenib

Background

The application of medical image three-dimensional (3D) reconstruction technology can provide intuitive 3D image data support for accurate preoperative evaluation, surgical planning, and operation safety. However, there is still a lack of high-quality evidence to support whether 3D reconstruction technology is more advantageous in liver resection. Therefore, this study systematically evaluated the clinical effects of 3D reconstruction and two-dimensional (2D) image-assisted hepatectomy.

Methods

Databases were searched to collect published clinical studies on 3D reconstruction technology and 2D image-assisted liver resection. Data were extracted from the database construction to March 2022 and the risk of bias in the included studies was evaluated. Meta-analysis was performed using RevMan5.3 software.

Results

A total of 13 clinical studies were included, including 1616 patients, 795 in the 2D group and 819 in the 3D group. The meta-analysis showed that the incidence of postoperative complications was lower in the 3D group than in the 2D group (OR = 0.64, 95% CI = 0.49–0.83, P=0.001) and also reduced operation time (SMD = −0.51, 95% CI = −0.74∼−0.27, P < 0.0001), decreased intraoperative blood loss (SMD = −63.85, 95% CI = −98.66–29.04, P=0.0003), decreased incidence of postoperative liver failure (OR = 2.42, 95% CI = 0.99–5.95, P=0.05), decreased postoperative recurrence rate (OR = 0.29, 95% CI = 0.16–0.53, P < 0.0001), and increased postoperative survival rate (OR = 2.19, 95% CI = 1.49–3.23, P < 0.0001).

Conclusions

Current data suggest that 3D reconstruction-assisted hepatectomy can reduce intraoperative blood loss, postoperative complications, and recurrence, and improve postoperative survival. Therefore, the 3D reconstruction technique is worthy of application and promotion in assisted liver resection.

Effects of Laparoscopic versus Open Surgery for Advanced Gastric Cancer after Neoadjuvant Chemotherapy: A Meta-Analysis

Objective. To evaluate the efficacy of laparoscopy and laparotomy after neoadjuvant chemotherapy in the treatment of advanced gastric cancer by meta-analysis. Methods. Cochrane Library, Embase, and PubMed were searched by computer until December 1, 2021. Literature was screened according to inclusion and exclusion criteria, and relevant data were extracted for meta-analysis using RevMan 5.3. Results. A total of 1027 patients from 11 literature studies were included in this study, including 413 patients in the laparoscopic group and 614 patients in the open group. Meta-analysis showed that the laparoscopic group had less intraoperative bleeding (SMD = −1.11; 95% CI: −1.75–0.47; $P=0.0006$ ), early postoperative exhaust (SMD = −0.45; 95% CI: −0.70–0.20; $P=0.0004$ ), and shorter postoperative hospital stay (SMD = 0.97; 95% CI: 1.69∼0.26; $P=0.008$ ), but had longer the operation time (SMD = 0.65; 95% CI: 0.52∼0.79; $P<0.00001$ ). There was no significant difference in the number of lymph nodes dissected during operation (SMD = −0.45; 95% CI: −0.42–0.19; $P=0.45$ ), the incidence of surgical complications 30 days after operation (OR = 0.78; 95% CI: 0.53∼1.13; $P=0.19$ ), time of first defecation (MD = 0.00; 95% CI: −0.10∼0.10; $P=0.98$ ), and time of first postoperative feeding (MD = −0.05; 95% CI: −0.22∼0.12; $P=0.54$ ) between the two groups. For long-term prognosis, there was no significant difference in the 3-year overall survival rate after operation between the two groups (RR = 0.84; 95% CI: 0.63–1.12; $P=0.23$ ). Conclusion. Compared with the open stomach cancer surgery, laparoscopic gastric cancer surgery has less intraoperative blood loss, shorter hospitalization time, and advantages such as early rehabilitation, postoperative complications rate, and long-term survival, which confirmed the validity and security of the laparoscopic surgery.

Clinical Experience of Intracorporeal Hand-sewn Anastomosis Following Totally Laparoscopic Pylorus-Preserving Gastrectomy for Middle-Third Early Gastric Cancer

INTRODUCTION

Pylorus-preserving gastrectomy (PPG) has been accepted as a representative function-preserving procedure for early gastric cancer (EGC) in the middle stomach. Totally, intracorporeal laparoscopic gastrectomy can provide better aesthetics, be less invasive, and allow faster postoperative recovery. Here, we first describe the surgical procedure of totally laparoscopic pylorus-preserving gastrectomy with intracorporeal hand-sewn anastomosis (TLPPG-IHSA).

METHODS

After standard procedure of lymph node dissection and middle stomach resection, we used two double-needle barbed sutures to perform a layer-to-layer manual anastomosis of the anterior and posterior walls in the abdominal cavity. Twelve patients with preoperatively diagnosed clinical EGC located in the middle third of the stomach underwent TLPPG-IHSA between August 2019 and January 2021.

RESULTS

A total of 12 patients with EGC successfully underwent TLPPG-IHSA. Only one patient (8.3%) suffered postoperative gastric stasis. No complications or recurrence occurred in other patients during half a year after surgery.

CONCLUSION

TLPPG-IHSA is considered technically feasible to treat EGC located in the middle third of the stomach.

Postoperative quality of life after gastrectomy in gastric cancer patients: a prospective longitudinal observation study

Purpose

The European Organization for Research and Treatment of Cancer quality of life (QOL) questionnaires (QLQ-C30, QLQ-OG25, and QLQ-STO22) are widely used for the assessment of gastric cancer patients. This study aimed to use these questionnaires to evaluate QOL in postgastrectomy patients.

Methods

We prospectively evaluated 106 patients with distal gastrectomy (DG), 57 with pylorus-preserving gastrectomy (PPG), and 117 with total gastrectomy (TG). Body weight and QOL questionnaires were evaluated preoperatively and postoperatively (at 3 weeks, and 3, 6, and 12 months).

Results

TG patients had significantly more weight loss than DG/PPG patients. Compared with DG, patients after PPG had less dyspnea (P = 0.008) and trouble with coughing (P = 0.049), but more severe symptoms of insomnia (P = 0.037) and reflux (P = 0.030) at postoperative 12 months. Compared with DG/PPG, TG was associated with worse body image, dysphagia, eating, and taste in both OG25 and STO22. Moreover, OG25 revealed worse QOL in the TG group with respect to odynophagia, eating with others, choked when swallowing, trouble talking, and weight loss. The QOL of patients who received chemotherapy was worse than those in the chemo-free group in both physical functioning and symptoms such as nausea/vomiting, appetite loss, and trouble with taste; however, these side effects would soon disappear after finishing chemotherapy.

Conclusion

PPG was similar to DG in terms of postoperative QOL and maintaining body weight, while TG was always inferior to both DG and PPG. Adjuvant chemotherapy can affect both body weight and QOL despite being reversible.

Life prognosis of sentinel node navigation surgery for early-stage gastric cancer: Outcome of lymphatic basin dissection

BACKGROUND

Lymphatic basin dissection is a sentinel node biopsy method that is specific for gastric cancer. In this method, the dyed lymphatic system is dissected en bloc, and sentinel nodes are identified at the back table (ex vivo). Even with lymphatic basin dissection, blood flow to the residual stomach can be preserved, and function-preserving curative gastrectomy can be performed. The oncological safety of function-preserving curative gastrectomy combined with lymphatic basin dissection has not yet been fully investigated. We hypothesized that the oncological safety of sentinel node navigation surgery (SNNS) is not inferior to that of the guidelines.

AIM

To investigate the life prognosis of SNNS for gastric cancer in comparison with guidelines surgery.

METHODS

This was a retrospective cohort study. Patients were selected from gastric cancer patients who underwent sentinel node biopsy from April 1999 to March 2016. Patients from April 1999 to August 2008 were from the Department of Surgery II, Kanazawa University Hospital, and patients from August 2009 to March 2016 were from the Department of Surgical Oncology, Kanazawa Medical University Hospital. Patients who were diagnosed with gastric cancer, which was preoperatively diagnosed as superficial type (type 0), 5 cm or less in length, clinical T1-2 and node negative, and underwent various gastrectomies guided by sentinel node navigation were retrospectively collected. The overall survival (OS) and relapse-free survival (RFS) of these patients (SNNS group) were investigated. Patients with gastric cancer of the same stage and who underwent guidelines gastrectomy with standard nodal dissection were also selected as the control group.

RESULTS

A total of 239 patients in the SNNS group and 423 patients in the control group were included. Pathological nodal metastasis was observed in 10.5% and 10.4% of the SNNS and control groups, respectively. The diagnostic abilities of sentinel node biopsy were 84% and 98.6% for sensitivity and accuracy, respectively. In the SNNS group, 81.6% of patients underwent modified gastrectomy or function-preserving curative gastrectomy with lymphatic basin dissection, in which the extent of nodal dissection was further reduced compared to the guidelines. The OS rate in the SNNS group was 96.8% at 5 years and was significantly better than 91.3% in the control group (P = 0.0014). The RFS rates were equal in both groups. After propensity score matching, there were 231 patients in both groups, and the cumulative recurrence rate was 0.43% at 5 years in the SNNS group and 1.30% in the control group, which was not statistically different.

CONCLUSION

The oncological safety of patients who undergo gastrectomy guided by sentinel node navigation is not inferior to that of the guidelines surgery.

The risk of lymph node metastasis in gastric cancer conforming to indications of endoscopic resection and pylorus-preserving gastrectomy: a single-center retrospective study

Background

Lymph node metastasis (LNM) status is an important prognostic factor that strongly influences the treatment decision of early gastric cancer (EGC). This study aimed to evaluate the pattern and clinical significance of LNM in EGC.

Methods

A total of 354 patients with carcinoma in situ (n = 42), EGC (n = 312) who underwent radical gastrectomy were enrolled. Their clinicopathological features, pathological reports, and prognostic data were collected and analyzed.

Results

The incidence of LNM in all patients was 18.36% (65/354). The rates of D1 and D2 station metastases were 12.10% (43/354) and 6.21% (22/354), respectively. The rates of LNM in absolute indication of endoscopic resection and expanded indication were 3.27% (2/61) and 28.55% (4/14), respectively. Skip LNM was observed in 3.67% (13/354) of patients. For those with middle-third tumor, the metastasis rate of the No. 5 lymph node was 3.05% (5/164). The independent risk factors for LNM were tumors measuring > 30 mm, poorly differentiated tumors, and lymphovascular invasion (all P < 0.05; area under the curve, 0.783). The 5-year disease-free survival rates of patients with and without LNM were 96.26 and 79.17%, respectively (P = 0.011). Tumors measuring > 20 mm and LNM were independent predictive factors for poor survival outcome in all patients.

Conclusions

Patients with EGC conforming to expanded indications have a relatively high risk of LNM and may not be suitable for endoscopic submucosal dissection. Pylorus-preserving gastrectomy for patients with middle-third EGC remains controversial due to the high metastasis rate of the No. 5 lymph node.

A comparison of quality of life between patients with small and large gastric remnant volumes after gastrectomy for gastric cancer

The impact of gastric remnant volumes (GRVs) after gastrectomy on patients' quality of life (QOL) has not yet been clarified. The aim of the present study was to compare QOL after gastrectomy between small and large gastric remnant volume patients.We prospectively collected clinical data from 78 consecutive patients who underwent distal gastrectomy with Billroth II gastrojejunostomy for gastric cancer. The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Stomach questionnaire and gastric computed tomography scans were performed. The patients were subdivided into 2 groups by remnant stomach volume (the S group ≤110 mL vs L group >110 mL).The worst scores for most items were observed at postoperative month 1 and usually improved thereafter. There was no difference in the STO22 score except for dysphagia between the S and L groups after gastrectomy (P > .05). The QOL score of dysphagia was different at postoperative 6 months (S vs L, 12.4 vs 22.8, P < .03), but there was no difference at postoperative months 1, 3, 12, 24, or 36 (P > .05).The remnant gastric volume after partial gastrectomy affects neither functional differences nor QOL after 6 months following appropriate radical surgery.

Current indications for endoscopic submucosal dissection of early gastric cancer

The development of endoscopic treatment technology has further promoted the minimally invasive treatment of early gastric cancer (EGC). Endoscopic treatment has achieved better therapeutic effects in terms of safety and prognosis and is the preferred treatment method for patients who meet the indications for endoscopic treatment. However, the consequent problem is that some patients receiving endoscopic treatment may undergo non-curative resection, and the principle of follow-up management for non-curative resection patients deserves further attention. In addition, there are still debates on how to improve the accuracy of clinical staging, select a reasonable treatment method for patients who meet the expanded indications for endoscopic treatment, manage patients with positive endoscopic surgical margins, conduct research on function-preserving surgery, and manage the treatment of EGC under the current situation in China. Consequently, we aim to review current indications for endoscopic submucosal dissection of EGC in order to better inform treatment options.

Comparison of effects of six main gastrectomy procedures on patients’ quality of life assessed by Postgastrectomy Syndrome Assessment Scale-45

BACKGROUND

The effects of various gastrectomy procedures on the patient’s quality of life (QOL) are not well understood. Thus, this nationwide multi-institutional cross-sectional study using the Postgastrectomy Syndrome Assessment Scale-45 (PGSAS-45), a well-established questionnaire designed to clarify the severity and characteristics of the postgastrectomy syndrome, was conducted.

AIM

To compare the effects of six main gastrectomy procedures on the postoperative QOL.

METHODS

Eligible questionnaires retrieved from 2368 patients who underwent either of six gastrectomy procedures [total gastrectomy with Roux-en-Y reconstruction (TGRY; n = 393), proximal gastrectomy (PG; n = 193), distal gastrectomy with Roux-en-Y reconstruction (DGRY; n = 475), distal gastrectomy with Billroth-I reconstruction (DGBI; n = 909), pylorus-preserving gastrectomy (PPG; n = 313), and local resection of the stomach (LR; n = 85)] were analyzed. Among the 19 main outcome measures of PGSAS-45, the severity and characteristics of postgastrectomy syndrome were compared for the aforementioned six gastrectomy procedures using analysis of means.

RESULTS

TGRY and PG significantly impaired the QOL of postoperative patients. Postoperative QOL was excellent in LR (cardia and pylorus were preserved with minimal resection). In procedures removing the distal stomach, diarrhea subscale (SS) and dumping SS were less frequent in PPG than in DGBI and DGRY. However, there was no difference in the postoperative QOL between DGBI and DGRY. The most noticeable adverse effects caused by gastrectomy were meal-related distress SS, dissatisfaction at the meal, and weight loss, with significant differences among the surgical procedures.

CONCLUSION

Postoperative QOL greatly differed among six gastrectomy procedures. The severity and characteristics of postgastrectomy syndrome should be considered to select gastrectomy procedures, overcome surgical shortcomings, and enhance postoperative care.
