Perioperative outcomes of transvaginal specimen extraction laparoscopic total gastrectomy and conventional laparoscopic-assisted total gastrectomy. World J Gastrointest Surg 2024; 16:1527-1536. [PMID: 38983348 PMCID: PMC11230027 DOI: 10.4240/wjgs.v16.i6.1527] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Revised: 02/20/2024] [Accepted: 05/24/2024] [Indexed: 06/27/2024] Open
Abstract
BACKGROUND Natural orifice specimen extraction surgery (NOSES) has emerged as a promising alternative compared to conventional laparoscopic-assisted total gastrectomy (LATG) for treating gastric cancer (GC). However, evidence regarding the efficacy and safety of NOSES for GC surgery is limited. This study aimed to compare the safety and feasibility, in addition to postoperative complications of NOSES and LATG. AIM To discuss the postoperative effects of two different surgical methods in patients with GC. METHODS Dual circular staplers were used in Roux-en-Y digestive tract reconstruction for transvaginal specimen extraction LATG, and its outcomes were compared with LATG in a cohort of 51 GC patients with tumor size ≤ 5 cm. The study was conducted from May 2018 to September 2020, and patients were categorized into the NOSES group (n = 22) and LATG group (n = 29). Perioperative parameters were compared and analyzed, including patient and tumor characteristics, postoperative outcomes, and anastomosis-related complications, postoperative hospital stay, the length of abdominal incision, difference in tumor type, postoperative complications, and postoperative survival. RESULTS Postoperative exhaust time, operation duration, mean postoperative hospital stay, length of abdominal incision, number of specific staplers used, and Brief Illness Perception Questionnaire score were significant in both groups (P < 0.01). In the NOSES group, the postoperative time to first flatus, mean postoperative hospital stay, and length of abdominal incision were significantly shorter than those in the LATG group. Patients in the NOSES group had faster postoperative recovery, and achieved abdominal minimally invasive incision that met aesthetic requirements. There were no significant differences in gender, age, tumor type, postoperative complications, and postoperative survival between the two groups. CONCLUSION The application of dual circular staplers in Roux-en-Y digestive tract reconstruction combined with NOSES gastrectomy is safe and convenient. This approach offers better short-term outcomes compared to LATG, while long-term survival rates are comparable to those of conventional laparoscopic surgery.

Double stapling technique versus hemi-double stapling technique for esophagojejunostomy with OrVil™ after laparoscopic total gastrectomy: a single-blind, randomized clinical trial. Surg Endosc 2023:10.1007/s00464-023-10068-z.

Abstract
BACKGROUND The transorally inserted anvil (OrVil™) is frequently selected for esophagojejunostomy after laparoscopic total gastrectomy (LTG) because of its versatility. During anastomosis with OrVil™, the double stapling technique (DST) or hemi-double stapling technique (HDST) can be selected by overlapping the linear stapler and the circular stapler. However, no studies have reported the differences between the methods and their clinical significance. METHODS A randomized controlled clinical trial with a parallel assignment and single-blind outcomes assessment analysis was conducted. Patients with gastric cancer eligible for LTG who met the selection criteria were randomized. Preoperative characteristics and perioperative and postoperative outcomes were compared between the DST and HDST. The primary endpoint was an anastomosis-related complication, and the secondary endpoints were perioperative outcomes and postoperative complications, excluding anastomosis-related complications. RESULTS Thirty patients with gastric cancer were eligible and randomized. LTG and esophagojejunostomy were successfully performed in all patients, without conversion to laparotomy. Preoperative characteristics, excluding preoperative chemotherapy, were not significantly different between the two groups. One anastomotic leakage of Clavien-Dindo classification grade ≥ IIIa was observed in the DST, although no significant difference was found between the two groups (6.6% vs. 0%, P = 0.30). In the HDST, one case of anastomotic stricture required endoscopic balloon dilation. No significant differences were found in operative time, whereas the anastomosis time was significantly shorter in the HDST than in the DST (47.5 ± 15.8 vs. 38.2 ± 8.8 min, P = 0.028). Except for anastomosis-related complications, postoperative complications (P = 0.282) and postoperative hospital stay for the DST and HDST were not significantly different. CONCLUSIONS No superiority was found between the DST and HDST with OrVil™ in esophagojejunostomy of LTG for gastric cancer with respect to postoperative complications, whereas the HDST may be preferable in terms of the simplicity of the surgical technique.

Walsh TN. The Esophagogastric Anastomosis: The Importance of Anchoring Sutures in Reducing Anastomotic Leak Rates. ANNALS OF SURGERY OPEN 2023; 4:e231. [PMID: 37600864 PMCID: PMC10431275 DOI: 10.1097/as9.0000000000000231] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2022] [Accepted: 11/29/2022] [Indexed: 02/04/2023] Open
Abstract
Background The incidence of anastomotic leakage in gastrointestinal surgery is highest after esophagogastric anastomosis, with leakage rates of 10% to 38% still being reported, but little consensus as to cause or corrective. The role of anastomotic tension from a series of physiological forces acting on the anastomosis from the moment of recovery from anesthesia may be underestimated. It was hypothesized that anchoring the conduit in the mediastinum would provide the greatest protection during the vulnerable healing phase. Patients and Methods A prospectively maintained database was interrogated for anastomotic leakage following the introduction of an anastomotic technique employing anchoring sutures where the gastric conduit was secured to the mediastinal pleura with 3 obliquely inserted load-bearing sutures. A contrast study was performed between days 5 and 7 and all intrahospital mortalities underwent autopsy. Clinical, radiological, and autopsy leaks were recorded. Results Of 146 intrathoracic esophagogastric anastomoses in 144 patients, 81 (55%) of which were stapled, there was 1 clinical leak and 1 patient with an aortoenteric fistula, considered at autopsy to be possibly due to an anastomotic leak, to give an anastomotic leak rate of 2 in 146 (1.37%). Conclusion The low anastomotic leak rate in this series is potentially due to the protective effect of anchoring sutures, the chief difference from an otherwise standard anastomotic technique. These sutures protect the anastomosis from a series of distracting forces during the most vulnerable phase of healing. It is intuitive that the absence of tension would also reduce any risk posed by a minor impairment of blood supply or any imperfection of the technique.

Abstract
BACKGROUND Esophageal anastomoses performed following esophagectomy and total gastrectomy are technically challenging with a significant risk of anastomotic leak. A safe, reliable, and easy anastomotic technique is required to improve patient outcomes and reduce morbidity. METHOD This paper analyses 328 consecutive patients who underwent transoral circular stapled esophageal anastomosis (ORVIL™) from a prospectively collected single-center database between December 2011 and February 2019. RESULTS Two hundred and twenty-seven esophagectomies and 101 gastrectomies were performed using OrVil™ anastomoses. The mean patient age was 63.7 years. Of 328 consecutive OrVil™-based anastomoses, there were 10 clinically significant anastomotic leaks requiring radiological or operative intervention (3.05%). Twenty-eight (8.54%) patients developed anastomotic stricture, all of which were successfully treated with endoscopic balloon dilatation (a median of 1 dilatation was required per patient). CONCLUSION The OrVil™ anastomotic technique is reliable and safe to perform. This is the largest reported series of the OrVil™ anastomotic technique to date. Leak rates and anastomotic dilations were similar to other reported series. Based on our experience, we consider the use of the OrVil™ device for reconstruction after major upper GI resection to be safe and reliable.

Abstract
The esophagogastric anastomosis is most commonly performed to restore digestive tract continuity after esophagectomy for cancer. Despite a long history of clinical research and development of high-tech staplers, this procedure is still feared by most surgeons and associated with a 10% leakage rate. Among specific factors that may contribute to failure of the esophageal anastomosis are the absence of serosa layer, longitudinal orientation of muscle fibers, and ischemia of the gastric conduit. It has recently been suggested that the gut microbiome may influence the healing process of the anastomosis through the presence of collagenolytic bacterial strains, indicating that suture breakdown is not only a matter of collagen biosynthesis. The esophagogastric anastomosis can be performed either in the chest or neck, and can be completely hand-sewn, completely stapled (circular or linear stapler), or semi-mechanical (linear stapler posterior wall and hand-sewn anterior wall). Because of the lack of randomized clinical trials, no conclusive evidence is available, and the debate between the hand-sewn and the stapling technique is still ongoing even in the present era of robotic surgery. Centralization of care has improved the overall postoperative outcomes of esophagectomy, but the esophagogastric anastomosis remains the Achille’s heel of the procedure. More research and network collaboration of experts is needed to improve safety and clinical outcomes.

Abstract
PURPOSE Many reconstruction techniques have been reported after laparoscopic total gastrectomy (LTG), but it is not clear which anastomosis technique is most useful, and no standard methods have been established. This study examined whether LTG using the transoral anvil delivery system (TOADS) is a feasible and safe procedure for gastric cancer. MATERIALS AND METHODS A series of 47 patients underwent the overlap method and 36 underwent the hemi-double-stapling technique with TOADS. Intraoperative and postoperative outcomes were compared between the 2 groups. RESULTS In the TOADS group, operation time for reconstruction was shorter (16±3 vs. 45±10 min, P=0.003), and blood loss was reduced (45±15 vs. 126±13 mL, P=0.0002). There were no significant differences in intraoperative complications, conversion to open surgery, and intraoperative anastomosis-related complications between the 2 groups. Furthermore, there were no significant differences in the incidence of complications, reoperation, mortality, and postoperative hospital stay. CONCLUSION LTG using TOADS for gastric cancer may be a technically feasible surgical procedure with acceptable morbidity.

Abstract
BACKGROUND Laparoscopic total gastrectomy (LTG) is frequently performed for treating patients with gastric cancer; however, the absence of anastomotic techniques with greater superiority has impaired its popularization. We have compared two types of anastomotic techniques with regard to technical perspectives and clinical outcomes. METHODS We reviewed 43 patients with gastric cancer who underwent LTG. Two types of anastomotic techniques have been applied after LTG-the trans-orally inserted anvil (OrVil™) and the reverse puncture device (RPD). Data on the type of anastomosis, blood loss, operation time, anastomosis time, location of tumors, distance between the top border of tumors and top resection margin, diameter of tumor, length of postoperative hospital stay, early and late postoperative complications, and total cost of surgical consumables were obtained by reviewing patient medical records and analyzed thereafter. RESULTS We included 32 men and 11 women (mean age 61 years). The loss to follow-up rate was 13.2%. The median survival time for the OrVil™ and RPD groups was 23 and 22 months, respectively. The total rate of complications was 9.3%. The difference in the anastomosis times between the groups was statistically significant. OrVil™ required more time than RPD and cost more than RPD. CONCLUSIONS Both the OrVil™ and RPD techniques showed good safety and applicability in LTG. RPD showed an advantage with regard to lesser operative complexity and lower cost.

Abstract
Purpose To present the feasibility and safety of Roux-en-Y esophagojejunostomy using hemi-double-stapling technique after laparoscopic total gastrectomy. Methods We reviewed the outcomes from 58 consecutive patients with gastric cancer who underwent laparoscopic total gastrectomy. The clinicopathological characteristics including postoperative complications were examined. Results The mean age and body mass index were 57.3 ± 9.7 years and 23.7 ± 2.6 kg/m2, respectively. The mean overall total operation was 199.8 ± 57.0 minutes. Intraoperative blood loss was 81.6 ± 56.3 mL and there was no open conversion. The patients' hospital stay was a mean 9.6 ± 2 days. The mean proximal margin of the specimens was 2.7 ± 1.8 cm. There were 3 cases (5.1%) of anastomosis leakage, but all were controlled successfully by endoscopic stent. Conclusion The circular HDST technique is simple and reliable without any significant demerits with respect to safety concerns or difficulty of operation.

Abstract
BACKGROUND AND OBJECTIVES Loss of visualization of the surgical field due to pneumoperitoneum deflation when CO2 insufflator cylinders become empty can occur at key moments during laparoscopic surgery. The purpose of this study was to examine the incidence of intraoperative cylinder exhaustion in the United Kingdom, determine its impact on patient safety, and design and test a novel device to minimize the phenomenon. METHODS We performed a national cross-sectional survey of U.K. surgeons, inviting all members of the Association of Surgeons of Great Britain and Ireland (ASGBI) and the Association of Upper GI Surgeons (AUGIS) to participate. We designed and tested a novel dual-valve system to allow rapid intraoperative exchange of CO2 cylinders. RESULTS Eighty-five percent of the U.K. surgeons surveyed reported loss of surgical visualization at critical times during laparoscopic surgery, caused by the decrease in pneumoperitoneum during CO2 cylinder exchange. Eighty-four percent said that the process contributed to the surgeon's stress, and 63% said that a device that maintains uninterrupted pneumoperitoneum would reduce the risk of intraoperative complications. In our locale, a timed cylinder exchange was, on average, 30 times quicker with the novel dual valve than by conventional cylinder exchange (mean conventional exchange time, 61.3 ± 7.3 s vs. novel device, 2.0 ± 0.2 s; P ≤ .0001) and could be performed just as rapidly by staff unfamiliar with the device (2.2 ± 0.3 s vs. 1.9 ± 0.4 s P = .1945). We suggest that this simple, low-cost system could be developed for use in a clinical setting to enhance patient safety.

Abstract
For many years, open gastrectomy with lymphadenectomy was the gold standard treatment for gastric cancer. In recent years, however, laparoscopic assisted total gastrectomy with associated D2 lymphadenectomy has gained in popularity. It has a similar oncological outcome to open resection, but has all of the added advantages of a laparoscopic procedure, such as early mobilisation, less postoperative pain and shorter hospital stay. This article describes the operative techniques, including key procedure steps, as well as a guide for using the new OrVil device for the laparoscopic creation of the oesophago-jejunal anastomosis. A video of a laparoscopic assisted total gastrectomy is presented.
