A preliminary study of modified inflatable mediastinoscopic and single-incision plus one-port laparoscopic esophagectomy. J Thorac Dis 2024; 16:2472-2481. [PMID: 38738243 PMCID: PMC11087624 DOI: 10.21037/jtd-24-309] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2024] [Accepted: 04/10/2024] [Indexed: 05/14/2024]
Abstract
Background Esophageal malignancies have a high morbidity rate worldwide, and minimally invasive surgery has emerged as the primary approach for treating esophageal cancer. In recent years, there has been increasing discussion about the potential of employing inflatable mediastinoscopic and laparoscopic approaches as an option for esophagectomy. Building on the primary modification of the inflatable mediastinoscopic technique, we introduced a secondary modification to further minimize surgical trauma. Methods We conducted a retrospective analysis of patients who underwent inflatable mediastinoscopy combined with laparoscopic esophagectomy at the Second Affiliated Hospital of Naval Medical University from March 2020 to March 2023. The patients were allocated to the following two groups: the traditional (primary modification) group, and the secondary modification group. Operation times, intraoperative bleeding, and postoperative complications were compared between the groups. Results The procedure was successfully performed in all patients, and conversion to open surgery was not required in any case. There were no statistically significant differences in the surgical operation time, intraoperative bleeding, number of dissected lymph nodes, and rate of postoperative anastomotic leakage between the two groups. However, a statistically significant difference was observed in the length of the mobilized esophagus between the two groups. The mobilization of esophagus to the level of diaphragmatic hiatus via the cervical incision was successfully achieved in more patients in the secondary modification group than the primary modification group. Conclusions Inflatable mediastinoscopy combined with single-incision plus one-port laparoscopic esophagectomy is a safe and effective surgical procedure. The use of a 5-mm flexible endoscope, ultra-long five-leaf forceps, and LigaSure Maryland forceps facilitates esophageal mobilization and lymph node dissection through a single cervical incision.

A case of indirect inguinal bladder hernia treated with laparoscopic transabdominal preperitoneal repair with high peritoneal incisional approach. Surg Case Rep 2024; 10:66. [PMID: 38503888 PMCID: PMC10951175 DOI: 10.1186/s40792-024-01860-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2023] [Accepted: 03/04/2024] [Indexed: 03/21/2024] Open
Abstract
BACKGROUND Inguinal herniation of the urinary bladder is uncommon and those descending into the scrotum are even rarer. Although open anterior repair has been used for inguinal bladder hernia, the efficacy of laparoscopic herniorrhaphy has been reported in recent years. CASE PRESENTATION A 63-year-old man presented with an irreducible right groin and scrotal bulge associated with voiding difficulty. Abdominal ultrasonography showed a dislocation of the urinary bladder descending into the right scrotum. Abdominal CT imaging revealed that a part of the bladder and small intestine was herniating into the scrotum through the internal inguinal ring and running laterally to the inferior epigastric artery. Under the diagnosis of indirect inguinal bladder hernia, the patient underwent trans-abdominal preperitoneal hernia repair (TAPP). The bladder herniated into the scrotum through the internal inguinal ring was replaced to the original position. Then the myopectineal orifice was exposed and covered with polypropylene mesh, where a horizontal peritoneal incision 4 cm above the hernia orifice, i.e., the high peritoneal incision approach (HPIA), allowed an easy peeling of the peritoneum and hernia sac. The patient's postoperative course was uneventful and the voiding difficulty resolved. The patient continued to do well without recurrence at 20 months after surgery. CONCLUSION Preoperative evaluation with abdominal ultrasonography and CT scan allowed a precise diagnosis of a groin hernia with voiding difficulty. TAPP with HPIA was useful in the treatment of inguinal bladder hernia because this technique facilitated a quick confirmation of the hernia contents, secure dissection of the whole protruded bladder, and adequate replacement of the bladder to the original position without any injury.

Abstract
We report a case of pulmonary tuberculosis developed during chemotherapy for colon cancer. A 78-year-old man with dyspnea was referred to our hospital for the treatment of transverse colon cancer with duodenal invasion. Chemotherapy was initiated for severe respiratory dysfunction associated with emphysema. After 3 months of chemotherapy, the patient required hospitalization because of severe general fatigue and appetite loss. Pneumonia occurred on the 9th hospital day. Antibiotic therapies with cefotiam hydrochloride or tazobactam/piperacillin were ineffective, his respiratory condition gradually decreased, and thus, endotracheal intubation was required. The patient was finally diagnosed with pulmonary tuberculosis by acid-fast staining of the sputum. Antituberculosis therapy with rifampicin, isoniazid, and streptomycin was effective, and acid-fast staining became negative after 2 weeks of antituberculosis therapy. However, he could not withdraw from the ventilator support and died of cancer progression on the 94th hospital day. Because chemotherapies induce immunosuppression, a targeted screening for latent tuberculosis infection should be performed in patients with colorectal cancer who are highly at risk for tuberculosis before starting chemotherapy, and pulmonary tuberculosis should be ruled out when a patient develops symptoms of pneumonia during chemotherapy.

Clinicopathologic differences of gastric neoplasms between Helicobacter pylori-infected and -naïve patients: a multicenter retrospective analysis. J Gastroenterol 2024; 59:1-10. [PMID: 37855982 DOI: 10.1007/s00535-023-02050-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Accepted: 10/01/2023] [Indexed: 10/20/2023]
Abstract
BACKGROUND The incidence of gastric neoplasms in Helicobacter pylori (Hp)-naïve patients has recently increased due to a remarkable decrease in the Hp-infected population in Japan. We investigated the clinicopathologic differences between Hp-infected gastric neoplasms (HpIGNs) and Hp-naïve gastric neoplasms (HpNGNs) that have not been fully elucidated so far. METHODS This retrospective multicenter study investigated 966 consecutive patients with 1131 gastric dysplasia or cancers who underwent endoscopic or surgical treatment for the recent decade. Clinicopathologic features were compared between HpIGN and HpNGN cases. RESULTS One thousand and sixty-eight HpIGNs in 916 patients included 877 differentiated types and 191 undifferentiated types. Sixty-three HpNGNs in 50 patients included 57 differentiated types (35 foveolar types, 15 intestinal types, 6 fundic-gland types, and 1 other differentiated type) and 6 undifferentiated types. HpNGNs occurred in younger (59.5 vs. 71.8 years, p < 0.05) and female patients (40.0% vs. 26.5%, p < 0.05), were found more frequently in the proximal compartment (p < 0.05), and had smaller size (median 4.0 vs. 20.0 mm, p < 0.05). Histologically, HpNGNs and HpIGNs both primarily consisted of differentiated type (90.5% vs. 82.1%, p = 0.089) and HpNGNs showed lower prevalence of invasive cancer (11.1% vs. 37.6%, p < 0.05) and lymphovascular invasion (1.6% vs. 31.6%, p < 0.05). Nearly all HpNGNs (62/63, 98.4%) were diagnosed in early pathological stage, while 16.1% (172/1068) of HpIGNs were diagnosed in advanced stage (p < 0.05). CONCLUSIONS HpNGNs is recently on the increase but shows lower malignant nature regardless of histologic type than HpIGN. Endoscopic gastric cancer screening will be reviewed via cost effectiveness for Hp-naïve individuals in future.

Abstract
Background: Performing an intracorporeal esophagojejunostomy during laparoscopic-assisted total or proximal gastrectomy is challenging. We developed an ingenious method of overlapping esophagojejunostomy using a linear stapler to avoid stapler-related intraoperative complications. Methods: Following lymph node dissection, the esophagus was transected anterior-posteriorly. A linear stapler was used to divide the jejunum ∼20 cm distal to the Treitz ligament. A small enterotomy was then created 5 cm distal to the elevated jejunal stump to insert the linear stapler cartridge. An electronic knife was used to make a full-thickness incision, with the tip of the nasogastric tube (NGT) pressed against the posterior wall of the esophageal stump as a guide. Full-thickness sutures were placed on both the anterior and posterior walls of the entry hole in the esophageal stump to prevent the anvil fork from being misinserted into the submucosal layer of the esophagus. The thread on the posterior wall was guided through the port to the outside of the abdominal cavity, where the linear stapler was inserted to perform the side-to-side anastomosis. A 45-mm cartridge fork and an anvil fork were inserted into the elevated jejunum and esophageal stump entry holes, respectively, following which the esophageal stump was gently grasped. The thread on the posterior wall side was pulled from outside the abdominal cavity through the port. This step is necessary to close the gap between the esophageal and jejunal walls. After confirming that the anvil fork was not misinserted into the submucosal layer of the esophagus and that there was no gap between the esophagus and the elevated jejunum, the linear stapler was fired to create the anastomosis. The insertion hole was closed with hand-sewn sutures or linear staples to complete the esophagojejunostomy. Results: Eleven patients underwent this procedure with no anastomotic complications. Conclusions: This method enables us to perform an easier and more stable esophagojejunostomy.

Abstract
BACKGROUND Duplicated left gastric artery (LGA) is a rare anomaly. With an incidence of only 0.4%, its clinical significance remains largely unrecognized. CASE PRESENTATION A 65-year-old man underwent robot-assisted distal gastrectomy for early gastric cancer. After division of the left gastric vein in the left gastropancreatic fold, a slim LGA (LGA-1) was identified and dissected. Careful dissection of the left gastropancreatic fold toward the root of the celiac artery revealed another LGA (LGA-2), which was dissected without difficulty. Postoperative reevaluation of the three-dimensional-computed tomography (CT) angiography reconstructed using the preoperative CT scan identified a 2.7 mm LGA-1, branching from the splenic artery, and a 3.0 mm LGA-2, branching from the celiac artery. To the best of our knowledge, this is only the third reported case of a duplicate LGA in a patient who underwent laparoscopic gastrectomy. Our case is the first to report the use of robot surgery. CONCLUSIONS Although duplicate LGA is rare and receives little clinical attention, surgeons should keep this vascular anomaly in mind during preoperative evaluation since there is an increased risk for intraoperative bleeding during gastrectomy.

Abstract
Background: The lack of tension at the anastomosis site and the blood flow of the gastric conduit are important to prevent anastomotic leakage in the anastomosis of the esophagogastric conduit. This study reports a gastric conduit stump closure method using Endo GIA™ Radial Reload in end-to-side anastomosis of the esophagogastric conduit, especially focusing on blood flow. Methods: A 4-cm conduit was created to ensure an intramural vascular network. The gastric conduit was elevated to the neck through the posterior mediastinal route, and end-to-side anastomosis of the esophagus and gastric conduit was performed using a circular stapler. Closure of the gastric stump with an Endo GIA Radial Reload was performed 2 cm proximal to the anastomosis on the end side of the esophagogastric conduit. The lesser curvature of the stump of the gastric conduit is the most frequent site of anastomotic leakage as it has the least blood flow, and the pressure is highest when the pressure inside the gastric conduit increases. Therefore, the gastric conduit stump was closed using the Endo GIA Radial Reload to resect the intersection of the gastric stump and lesser curvature from which the gastric conduit was created. The gastric conduit stump is gently curved; therefore, the pressure applied to the gastric conduit stump could be dispersed when the intragastric pressure increases. Results: No anastomotic leakage was observed among the 21 patients who underwent this method. Conclusion: This method is a novel anastomosis method to prevent anastomotic leakage in an end-to-side anastomosis of the esophagogastric conduit.

Combination of neutrophil-to-lymphocyte ratio and albumin concentration to predict the prognosis of esophageal squamous cell cancer patients undergoing esophagectomy. J Thorac Dis 2023; 15:2224-2232. [PMID: 37197552 PMCID: PMC10183513 DOI: 10.21037/jtd-23-333] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Accepted: 04/07/2023] [Indexed: 05/19/2023]
Abstract
Background Esophageal squamous cell cancer (ESCC) is an aggressive cancer with high incidence and mortality. It is crucial to predict prognosis of these patients individually. Neutrophil-to-lymphocyte ratio (NLR) has been reported as a prognostic indicator in several tumors, including esophageal cancer. Besides inflammatory factors, nutritional status can impact survival of cancer patients. Albumin (Alb) concentration is an easily obtained indicator to reflect nutritional status. Methods In this study, we retrospectively collected the data of patients with ESCC and used univariate and multivariate analysis to investigate the relationship between combination of NLR and Alb (NLR-Alb) and survival. Meanwhile, we compared clinical features among NLR-Alb cohorts. Results Univariate analysis showed that age (P=0.013), gender (P=0.021), surgical type (P=0.031), preoperative therapy (P=0.007), NLR-Alb (P=0.001), and tumor-node-metastasis (TNM) status (P<0.001) were associated with 5-year overall survival (OS). In multivariate analysis, NLR-Alb [hazard ratio (HR) =2.53, 95% confidence interval (95% CI): 1.38-4.63, P=0.003] and TNM status (HR =4.76, 95% CI: 3.09-7.33, P<0.001) were independent predictive factors for 5-year OS. The 5-year OS rates were 83%, 62%, and 55% for NLR-Alb 1, NLR-Alb 2, and NLR-Alb 3, respectively (P=0.001). Conclusions In summary, pre-operative NLR-Alb is a favorable and cost-effective index to predict prognosis of patients with ESCC individually.

Abstract
BACKGROUND We focused on the lymphocyte-to-monocyte ratio (LMR), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) and devised an inflammation-combined prognostic index (ICPI) as a prognostic marker of cancer-specific survival (CSS). METHODS We reviewed the clinicopathological data of 480 patients with gastric cancer undergoing curative laparoscopic gastrectomy between 2009 and 2019. This study examined the significance of LMR, NLR, PLR, and ICPI as cancer-specific prognostic markers. RESULTS In univariate analysis, tumor diameter, histological differentiation, pathological tumor-node-metastasis (pTNM) stage, LMR, NLR, PLR, C-reactive protein (CRP) level, carcinoembryonic antigen (CEA), and postoperative chemotherapy were significantly associated with CSS. In multivariate analysis, pTNM stage and CEA were the independent risk factors for CSS, although LMR, NLR, and PLR were not the independent risk factors for CSS. The ICPI formula was constructed using hazard ratios for three inflammation-based biomarkers with worse prognosis identified in the univariate analysis: LMR <4.315, NLR ≥2.344, and PLR ≥212.01, which were each scored as 1, with all remaining values pointed at 0. ICPI was calculated as follows: ICPI = 2.9 × LMR + 2.8 × NLR + 2.8 × PLR. The optimal cutoff value of ICPII was 2.9. On multivariate analysis, pTNM stage, CEA, and ICPI were independent prognostic factors for CSS. In the Kaplan-Meier survival analysis, CSS in the high ICPI group was significantly worse than that in the low ICPI group. CONCLUSION ICPI was devised as a novel predictive index for prognosis, and its usefulness was clarified.

Features and applications of energy devices for prone robot-assisted minimally invasive esophagectomy: a narrative review. J Thorac Dis 2022; 14:3606-3612.

Abstract
Background and Objective Robot-assisted surgery is particularly useful in esophagectomy for esophageal cancer because robotic systems have high-resolution three-dimensional imaging, tremor filtering, and articulated instruments. This review article focuses on the applications and limitations of surgical devices in robot-assisted minimally invasive esophagectomy (RAMIE). Methods A narrative search of Medline was performed for articles published using the keywords “robot-assisted esophagectomy”, “technique”, “postoperative complication”, and “short-term outcomes”. Key Contents and Findings Monopolar scissors: these devices with a sharp tip have an articulating function that allows for fast, sharp dissection without an electrical source. However, scissor-type devices cannot compress the organ, and their hemostatic ability is rather weak. Maryland bipolar forceps: the device has a very thin tip that allows for accurate dissection as well as stronger hemostatic ability by closing the forceps to compress tissues and applying electric current. The disadvantage is longer operation time because the forceps need to be constantly closed and reopened. Long Maryland bipolar grasper: the tip of the long Maryland bipolar grasper is slightly blunt and has the advantage of versatility because it can grip the tissue more delicately. Ultrasonic scalpel: the device can transect tissues speedily without bleeding, shortening operation time, but lacks articulating function. Although thermal spread to the surroundings is relatively narrow, activation time increases with the amount of tissue to be grasped; this raises the temperature above that of the vessel sealer. Vessel sealer: the device is one of the most powerful hemostatic energy devices, based on bipolar electrodes. The articulating jaws on both sides are more suited for sharp transection rather than meticulous dissection because of its powerful hemostatic force and blunt tip. It is also important to note that the vessel sealer produces widespread high-temperature steam. SynchroSeal: the device offers fast activation time, and due to the tip of the device being finely divided, which requires relatively precise manipulation. Conclusions Robot-assisted surgery reduces the limitations of conventional endoscopic surgery by offering stable high-resolution three-dimensional imaging, tremor filtering, and articulated instruments. It is important to understand and exploit the advantages of energy devices suitable for RAMIE.

Feasibility study of adjuvant chemotherapy with S-1 after curative esophagectomy following neoadjuvant chemotherapy for esophageal cancer. BMC Cancer 2022; 22:718. [PMID: 35768866 PMCID: PMC9245214 DOI: 10.1186/s12885-022-09827-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2022] [Accepted: 06/24/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Despite advances in surgical techniques, long-term survival after esophagectomy for esophageal cancer remains unacceptably low, and more effective perioperative chemotherapy is expected. However, an important concern regarding the application of postoperative adjuvant chemotherapy is treatment toxicity. We aimed to evaluate the feasibility of adjuvant chemotherapy with S-1 in patients after esophagectomy. METHODS We investigated the tolerability of a 2-week administration followed by 1-week rest regimen of S1 as postoperative adjuvant therapy in 20 patients with esophageal squamous cell carcinoma who received neoadjuvant chemotherapy (NAC) and 22 patients who did not receive NAC during 2011-2020. RESULTS In the non-NAC group, the mean and median relative dose intensity (RDI) were 78.7% and 99.4%, respectively, and 11 patients (50%) had altered treatment schedules. The corresponding rates in the NAC group were 77.9% and 100%, respectively, and nine patients (45%) had altered treatment schedules, with no significant difference among the groups. Moreover, 17 patients (77.2%) in the non-NAC group and 16 patients (80.0%) in the NAC group continued S-1 treatment as planned for one year postoperatively, with no significant difference in the S-1 continuation rate (p = 0.500). Seventeen of 22 patients (77.3%) and 15 of 20 patients (75.0%) experienced several adverse events in the non-NAC and NAC groups, respectively. The frequency, severity, and type of adverse events were consistent among patients with and without NAC. CONCLUSIONS S-1 could be safely and continuously administered as adjuvant chemotherapy for patients with esophageal cancer regardless of NAC. Long-term prognosis should be evaluated for S-1 to become the standard treatment after esophagectomy.

Abstract
Background The prognostic value of the existing 8th edition post-neoadjuvant treatment (ypTNM) appears to be limited, and necessary reassessment and modification should be carried out as needed. This study aimed to compare the prognosis prediction accuracy of modified and unmodified versions of the 8th edition ypTNM. Methods Esophageal cancer patients who had received neoadjuvant therapy from the Surveillance, Epidemiology, and End Results (SEER) database were included in this observational longitudinal study. The median follow-up time was 26 months. All-cause mortality was the outcome variable. Demographic and clinical variables were collected as covariates. Kaplan-Meier (log-rank test) and Cox proportional hazards models were conducted for developing modified ypTNM staging. The concordance index (C-index) was calculated to analyze the discriminative ability of modified ypTNM staging. Results Overall, 3,595 patients met inclusion criteria. The 8th edition staging was not able to significantly discriminate between patients with ypT1- and ypT2-, ypT3- and ypT4-, ypN2- and ypN3- disease, respectively. Using the modified staging, we found that patients with ypT0–2 [hazard ratio (HR) =1.232; 95% confidence interval (CI): 1.053–1.441] and ypT3–4 (HR =1.257; 95% CI: 1.136–1.390) with grade III + IV had a significant risk of death compared to those with grade I + II. As was the case for the ypN0 (HR =1.295; 95% CI: 1.073–1.562) group with middle and upper tumor locations compared to those with low tumor location. The modified staging possessed better homogeneity in terms of the chi-square likelihood ratio (143.443 vs. 102.044), Akaike information criterion (AIC) (32,683.716 vs. 32,719.115), and Schwarz’s Bayesian criterion (SBC) (32,723.496 vs. 32,741.847), as well as better discriminatory ability (C-index of 0.577 vs. 0.560, P=0.045) compared to the 8th edition staging. Conclusions Although the modified ypTNM staging system we created by incorporating tumor grade and location to the original T and N displayed certain prognosis prediction accuracy compared with the 8th edition ypTNM staging, a larger sample size and prospective studies are needed to explore.

Abstract
Background: We assessed the relationship between preoperative prognostic nutritional index (PNI) and short- and long-term outcomes among gastric cancer patients because the clinical significance of PNI in these patients remains controversial. Materials and Methods: We retrospectively reviewed the medical records of 434 consecutive patients who underwent curative laparoscopic gastrectomy for gastric cancer. Results: Patients with postoperative complications had a significantly poorer overall survival (OS) than those without. On multivariate analyses, postoperative complications were independently associated with PNI value and operative procedure type. In the low PNI group (n = 118), those with postoperative complications experienced significantly poorer OS than those without complications. Among the low PNI group with pTNM stage I and II disease, those with postoperative complications experienced significantly worse OS than those without complications. However, among the high PNI group and patients with stage II and III disease in the low PNI group, OS was similar with respect to postoperative complications. Conclusions: The present study confirmed that long-term prognosis was unaffected by postoperative complications in well-nourished gastric cancer patients. In addition, preoperative nutritional status and postoperative complications, may be crucial in determining the prognosis of gastric cancer, especially in early-stage cancer.

[PMID: 34840755 PMCID: PMC8606878 DOI: 10.1016/j.amsu.2021.103001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2021] [Accepted: 10/28/2021] [Indexed: 11/17/2022] Open
Abstract
Introduction The overall incidence of port site hernias in laparoscopy and robot-assisted surgeries ranges from 0% to 5.2%. Sufficient port site closure is essential to reduce and prevent the occurrence of port site hernia. However, complete fascial closure of 8-mm robot-port site appears to be difficult. In this study, we propose a safe and reliable robot-assisted port-site closure for robot-assisted gastrectomy. Materials and methods The robotic arm was tilted 60–70° cranially or caudally to create a small gap between the port and the skin margin that was cut open for port insertion. While viewing through the robotic camera and grasping the polydioxanone (PDS) thread, the Lapa-Her-Closure was inserted into the peritoneal cavity through the gap. The Lapa-Her-Closure was removed after the PDS thread was grasped with robotic forceps. Subsequently, the Lapa-Her-Closure was inserted into the abdominal cavity by tilting the arm cranially or caudally, in contrast to the previous step. The PDS thread was inserted into the loop wire using robotic forceps. After tightening the loop wire and grasping the PDS thread, the Lapa-Her-Closure was removed, and the PDS thread was ligated to complete the abdominal wall closure, with total closure of the fascia and peritoneum. Results and conclusions We utilized this port site closure technique in 12 patients who underwent robot-assisted gastrectomy for gastric cancer. The procedure was accomplished safely and efficiently in all cases without any technical problems. In conclusion, our port site closure is safe, reliable, and efficient procedure that can be performed using basic surgical techniques. This study discusses a new approach in robot-assisted port site closure for robot-assisted gastrectomy. •Our study makes a significant contribution to the literature because it introduces a safe, reliable, and efficient approach of robot-assisted port site closure for robot-assisted gastrectomy to reduce the occurrence of hernias.

A safe and simple technique for nasogastric tube insertion in patients with thoracic esophageal cancer surgery. World J Surg Oncol 2021; 19:317. [PMID: 34732220 PMCID: PMC8564989 DOI: 10.1186/s12957-021-02428-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2021] [Accepted: 10/22/2021] [Indexed: 12/07/2022] Open
Abstract
BACKGROUND Risk factors for anastomotic leakage include local factors such as excessive tension across anastomosis and increased intraluminal pressure on the gastric conduit; therefore, we consider the placement of a nasogastric tube to be essential in reducing anastomotic leakage. In this study, we devised a safe and simple technique to place an NGT during an end-to-side, automatic circular-stapled esophagogastrostomy. METHODS First, a 4-0 nylon thread is fixed in the narrow groove between the plastic and metal parts of the tip of the anvil head. After dissecting the esophagus, the tip of the NGT is guided out of the lumen of the cervical esophageal stump. The connecting nylon thread is applied to the anvil head with the tip of the NGT. The anvil head is inserted into the cervical esophageal stump, and a purse-string suture is performed on the esophageal stump to complete the anvil head placement. The main unit of the automated stapler is inserted through the tip of a reconstructed gastric conduit, and the stapler is subsequently fired and an end-to-side esophagogastrostomy is achieved. The main unit of the automated stapler is then pulled out from the gastric conduit, and the NGT comes out with the anvil head from the tip of the reconstructed gastric conduit. Subsequently, the nylon thread is cut. After creating an α-loop with the NGT outside of the lumen, the tip of the NGT is inserted into the gastric conduit along the lesser curvature toward the caudal side. Finally, the inlet of the automated stapler on the tip of the gastric conduit is closed with an automated linear stapler, and the esophagogastrostomy is completed. RESULTS We utilized this technique in seven patients who underwent esophagectomy for esophageal cancer; smooth and safe placement of the NGT was accomplished in all cases. CONCLUSION Our technique of NGT placement is simple, safe, and feasible.

Abstract
Gastrointestinal stromal tumors (GISTs) develop in the digestive tract, mainly in the stomach, small intestine, colon, or esophagus. However, primary tumors with the same pathologic features as GISTs have been reported to occur outside of the digestive tract and are called extragastrointestinal stromal tumor (EGIST). We herein report a rare case of EGIST arising from the greater omentum in a patient with abdominal pain caused by intraperitoneal bleeding from the tumor.

Pyomyositis in a Patient Undergoing Chemotherapy for Gastric Cancer: A Case Report and Literature Review. Case Rep Oncol 2021; 14:1220-1227. [PMID: 34703439 PMCID: PMC8460931 DOI: 10.1159/000518242] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2021] [Accepted: 06/26/2021] [Indexed: 12/02/2022] Open
Abstract
Pyomyositis has recently been recognized as a primary infection of the large skeletal muscles, and it is often accompanied by single or multiple intramuscular abscess formation. Immunocompromised patients, including those with diabetes mellitus, human immunodeficiency virus infection, and cancer, as well as those undergoing chemotherapy, are at a greater risk of developing pyomyositis. A 78-year-old Japanese man with recurrent gastric cancer being treated with chemotherapy presented with sudden-onset pain in his left lower extremity while undergoing a second-line regimen with irinotecan. T2-weighted magnetic resonance imaging (MRI) showed an abnormally high-intensity signal in the left internal and external obturator muscles, a finding consistent with pyomyositis. Following intensive antibiotic treatment, the patient recovered completely and was able to resume chemotherapy with irinotecan. For a patient who developed pyomyositis during chemotherapy for gastric cancer, early diagnosis using MRI followed by administration of timely intensive antibiotic therapy resulted in complete recovery.

Abstract
BACKGROUND This study aimed to evaluate the feasibility, safety, and efficacy of postoperative adjuvant chemotherapy with docetaxel/cisplatin/S-1 (DCS) following S-1 therapy in patients with stage III gastric cancer after curative gastrectomy. METHODS Patients with stage III gastric cancer who underwent D2 gastrectomy were enrolled. Adjuvant chemotherapy was initiated within 8 weeks of gastrectomy. The first cycle of chemotherapy consisted of S-1 monotherapy (day 1-14), followed by a 7-day rest period. Cycles 2 and 3 consisted of the following: S-1 (day 1-14) administration, followed by a 14-day rest period, and an intravenous infusion of cisplatin and docetaxel on days 1 and 15. After two cycles, S-1 was administered for up to 1 year. RESULTS Thirty patients were enrolled between 2014 and 2017. Febrile neutropenia of grade 3 or higher was the most common hematological toxicity with 4 patients (13.3%). Other hematological toxicities of grade 3 or higher were as follows: neutropenia in 3 (10.0%), leukopenia in 3 (10.0%), and anemia in 2 (6.7%) patients. Most frequent non-hematological toxicity of grade 3 was anorexia (n = 4, 13.3%) and general fatigue (n = 3, 10.0%); no grade 4 non-hematological toxicities were observed. Twenty-five patients (83.3%) completed two cycles of DCS treatment and 18 (60.0%) completed subsequent S-1 treatment for 1 year. The relative dose intensity of docetaxel and cisplatin was 0.86 and that of S-1 was 0.88. CONCLUSION The DCS regimen can be acceptable as an adjuvant chemotherapy and offers an effective postoperative treatment option for stage III gastric cancer patients.

Abstract
Purposes The spread of coronavirus disease 2019 (COVID-19) has affected socioeconomic and healthcare systems in many countries. Accordingly, many individuals may have canceled their annual health-check programs, including esophagogastroduodenoscopy, which would have resulted in lower numbers of newly diagnosed patients with gastric cancer in comparison to other times. Methods Questionnaires were distributed to 62 hospitals every week from May 2020 to August 2020 (total 744) through mailing lists of the Stomach Cancer Study Group of the Japan Clinical Oncology Group. The number of patients with gastric cancer and hospital systems during the COVID-19 pandemic were surveyed. Results In total, 74% (551 out of 744) of the questionnaires were answered and analyzed. In early May, approximately 50% of hospitals had to restrict surgical slots due to the COVID-19 pandemic. However, they gradually loosened the restrictions thereafter. The number of gastrectomies was < 80% that of the same period in the previous year, and hospitals in Tokyo were seriously affected by a 50% decrease in the number of gastrectomies. Conclusions The number of gastrectomies was lower than that in the previous year. Further multi-center follow-up studies are required to evaluate the long-term effects of COVID-19 on the clinical outcomes of patients with gastric cancer.

Altemeier perineal rectosigmoidectomy with indocyanine green fluorescence imaging for a female adolescent with complete rectal prolapse: A case report. World J Clin Cases 2021; 9:847-853. [PMID: 33585631 PMCID: PMC7852635 DOI: 10.12998/wjcc.v9.i4.847] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/19/2020] [Revised: 12/17/2020] [Accepted: 12/27/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Rectal prolapse in young women is rare. Although laparoscopic ventral mesh rectopexy is the standard procedure because of its lower recurrence rate, postoperative infertility is a concern. Perineal rectosigmoidectomy (Altemeier procedure) is useful for these patients. However, the risk of anastomotic leakage should be considered. Recently, the usefulness of fluorescence imaging with indocyanine green (ICG) to prevent anastomotic leakage was reported. We report a case of an adolescent woman with complete rectal prolapse who underwent ICG fluorescence imaging-assisted Altemeier rectosigmoidectomy.
CASE SUMMARY A 17-year-old woman who had a mental disorder was admitted to our hospital for treatment for water intoxication. The patient also suffered from rectal prolapse, approximately 3 mo before admission. She was referred to our surgical department because recurrent rectal prolapse could worsen her psychiatric disorder. Approximately 10 cm of complete rectal prolapse was observed. However, the mean maximum anal resting and constriction pressures were within normal limits on anorectal manometry. Because she had the desire to bear children in the future, she underwent Altemeier perineal rectosigmoidectomy to prevent surgery-related infertility. We performed ICG fluorescence imaging at the same time as surgery to reduce the risk of anastomotic leakage. Her postoperative course was uneventful, and the rectal prolapse was completely resolved. She continued to do well 18 mo after surgery, without recurrence of the rectal prolapse.
CONCLUSION ICG fluorescence imaging-assisted Altemeier perineal rectosigmoidectomy is useful in preventing postoperative anastomotic leakage in young as well as elderly patients.

Abstract
Background: Inflammation influences cancer progression by increasing catabolism and impairing nutrient absorption. We compared the prognostic ability of three inflammation-based prognostic scoring systems—the Glasgow prognostic score (GPS), modified GPS (mGPS), and high-sensitivity mGPS (HS-mGPS)—in gastric cancer patients. Materials and Methods: We retrospectively examined 434 curatively resected gastric cancer patients to evaluate the prognostic ability of scoring systems for overall survival (OS) and cancer-specific survival (CSS). Results: OS analysis identified the following independent prognostic factors: GPS model: pathological stage (pStage, p < 0.001), carcinoembryonic antigen (CEA, p = 0.004), and GPS 1 (hazard ratio [HR], 1.929; 95% confidence interval [CI], 1.152-3.228; p = 0.013); mGPS model: body mass index (BMI, p = 0.027), pStage (p < 0.001), and CEA (p < 0.001); HS-mGPS model: BMI (p = 0.029), pStage (p < 0.001), and CEA (p = 0.003). mGPS and HS-mGPS were not independent prognostic factors for OS. CSS analysis of the GPS model identified pStage (p < 0.001), CEA (p = 0.015), and GPS 1 (HR; 2.095, 95% CI; 1.025–4.283; p = 0.043) and 2 (HR, 2.812; 95% CI, 1.111–7.116; p = 0.029) as independent prognostic factors; however, mGPS and HS-mGPS were not independent prognostic factors for CSS. Log-rank tests demonstrated significant differences in OS among patients with GPS 0 vs. 1 (p < 0.001) and 0 vs. 2 (p < 0.001) and in CSS among the three GPS (0 vs. 1; p = 0.005, 0 vs. 2; p < 0.001, 1 vs. 2; p = 0.009). Conclusions: GPS most reliably predicts long-term survival of gastric cancer patients.

Abstract
Case of esophageal cancer associated with an aberrant V2. Used preoperative 3D-CT for performing safe VATS-E. Preoperative contrast-enhanced 3D-CT clearly depicted the aberrant V2.
Background Subcarinal lymphadenectomy is an essential procedure in curative esophagectomy for esophageal cancer. The right superior pulmonary vein (RSPV) and its branches are usually located in front of the right main or intermediate bronchus. However, an anomalous posterior branch (aberrant V2) of RSPV passes behind the right intermediate bronchus, where the aberrant V2 may be embedded in the subcarinal nodal packet. This can lead to unanticipated bleeding when dissecting the subcarinal lymph node. We present a case study on the use of preoperative three-dimensional contrast-enhanced computed tomography (3D-CT) for performing a safe video-assisted thoracoscopic surgery-esophagectomy in lower thoracic esophageal cancer. Case presentation A 77-year-old man had esophageal cancer associated with an aberrant V2 passing behind the right intermediate bronchus. Esophagogastroduodenoscopy revealed a type 1 tumor in the lower thoracic esophagus. Contrast-enhanced and 3D-CT scans showed a space-occupying lesion with contrast enhancement and an aberrant V2 passing behind the right intermediate bronchus, respectively. The patient was then diagnosed with lower thoracic esophageal cancer (cT2cN1cM0 cStage II). As per the patient’s request, he underwent a surgery-first approach followed by adjuvant chemotherapy. The patient underwent video-assisted thoracoscopic surgery-esophagectomy (VATS-E) with three-field lymphadenectomy, and a large aberrant V2 involving the subcarinal nodal packet was recognized behind the right intermediate bronchus. After the thoracoscopic subtotal esophagectomy with three-field lymph node dissection, laparoscopy-assisted reconstruction of the esophagus was performed with elevation of the gastric conduit to the neck. Recurrent laryngeal nerve palsy was not observed. He started to receive rehabilitation for swallowing on day 3 and resumed oral intake on day 10 after surgery. The final pathological diagnosis was squamous cell carcinoma of the esophagus (pT3N1M0 pStageIII). Conclusions Preoperative contrast-enhanced 3D-CT clearly depicted the aberrant V2, which enabled us to perform a safe VATS-E with three-field lymphadenectomy. Thorough understanding of the anatomical configuration of the pulmonary vessels and bronchus is important for avoiding unexpected bleeding during subcarinal lymphadenectomy. 3D-CT imaging study is useful for recognizing the anomalous RSPV before surgery.

Abstract
The geriatric nutritional risk index (GNRI) is associated with mortality in several malignancies. We retrospectively analyzed whether the GNRI can predict long-term outcomes in 191 patients with esophageal squamous cell carcinoma (ESCC) after curative esophagectomies by evaluating their cancer-specific survival (CSS). In multivariate analyses, serum albumin (hazard ratio [HR], 2.498; p = 0.0043), GNRI (HR, 1.941; p = 0.0181), pathological tumor-node-metastasis (pTNM) stage (HR, 3.884; p < 0.0001), and tumor differentiation (HR, 2.307; p = 0.0066) were independent prognostic factors for CSS. In pTNM stage I, multivariate analysis identified C-reactive protein (HR, 7.172; p = 0.0483) and GNRI (HR, 5.579; p = 0.0291) as independent prognostic factors for CSS. In univariate analyses in pTNM stages II and III, only low GNRI (p = 0.0095) and low serum albumin levels (p = 0.0119), respectively, were significantly associated with worse CSS. In patients with low GNRI, CSS was significantly worse than in those with normal GNRI (p = 0.0011), especially in pTNM stages I (p = 0.0044) and II (p = 0.0036) groups, but not in stage III group (p = 0.5099). Preoperative GNRI may sort patients into low- or high-risk groups for shorter CSS, especially in those with pTNM stage I and II ESCC.

Abstract
Background: Systemic immune-inflammation index (SII)—comprising platelet, neutrophil, and lymphocyte count—is an objective and reliable biomarker for predicting the prognosis in cancer patients because it comprehensively reflects the balance between host inflammatory and immune responses. In this study, we clarified the prognostic impact of immunoinflammation-based indices, i. e. SII, neutrophil/lymphocyte ratio (NLR), and platelet/lymphocyte ratio (PLR), in gastric cancer patients.
Results: In multivariate analysis, the American Society of Anesthesiologists physical status (ASA-PS) (hazard ratio [HR]: 3.366, p < 0.001), tumor differentiation (HR: 1.705, p = 0.020), pathological Tumor, Node, Metastasis (pTNM) stage (HR: 2.160, p = 0.008), and carcinoembryonic antigen (CEA) (HR: 1.964, p = 0.003) were independent prognostic factors for OS in all patients. Further, multivariate analysis revealed that age (HR: 2.088, p = 0.040), ASA-PS (HR: 2.339, p = 0.043), tumor differentiation (HR: 1.748, p = 0.044), and pTNM stage (HR: 2.114, p = 0.024) were independent prognostic factors for OS among patients without inflammation; SII was not a prognostic factor for OS. Meanwhile, body mass index (HR: 5.055, p = 0.011), ASA-PS (HR: 3.403, p = 0.007), and SII (HR: 4.208, p = 0.026) were independent prognostic factors for OS among patients with inflammation.
Materials and Methods: We performed a retrospective review of 412 patients who underwent curative laparoscopic gastrectomy. The prognostic value of SII was compared between a low SII group (SII<661.9) and high SII group (SII≥661.9). We analyzed the predictive ability of immunoinflammation-based indices for overall survival (OS) based on a C-reactive protein (CRP) level of 0.5.
Conclusions: Compared to NLR and PLR, SII is the most significant prognostic biomarker for OS, especially in gastric cancer patients with inflammation.

Abstract
Background: The geriatric nutritional risk index (GNRI) was developed to evaluate the prognosis in elderly hospitalized patients at risk of malnutrition and related morbidity and mortality. This study aimed to evaluate the relationship between preoperative GNRI and long-term outcomes in elderly gastric cancer patients. Materials and Methods: We retrospectively reviewed 297 consecutive patients aged ≥ 65 years who underwent laparoscopic gastrectomy with R0 resection and evaluated their overall survival (OS) and cancer-specific survival (CSS). Results: In the univariate analyses, OS was significantly associated with the American Society of Anesthesiologists Physical Status (ASA-PS), tumor size, tumor differentiation, pathological stage, carcinoembryonic antigen (CEA), C-reactive protein, postoperative complications, and GNRI, whereas in the univariate analyses of CSS, ASA-PS, tumor size, tumor differentiation, pathological stage, CEA, postoperative adjuvant chemotherapy, and GNRI were significantly associated with poor prognosis. In the multivariate analysis, ASA-PS, tumor differentiation, pathological stage, and GNRI were significant independent prognostic factors of OS, whereas ASA-PS, pathological stage, and CEA were significant independent prognostic factors of CSS. Conclusions: GNRI is significantly associated with OS and CSS in elderly gastric cancer patients and is an independent predictor of OS. It is a simple, cost-effective, and promising nutritional index for predicting OS in elderly patients.

Abstract
INTRODUCTION The foreign body reaction caused by oil contrast medium, Lipiodol, is rare. We present a rare case of inflammatory granuloma in the inguinal hernia sac after hysterosalpingography with lipiodol. PRESENTATION OF CASE A 30-year-old woman who had left inguinal growing mass for 7 months after hysterosalpingography with Lipiodol for examination of infertile. About 3 cm soft mass was palpable on the left inguinal region, and plane CT scan showed a multifocal cystic mass with metal concentration. Thus, laparoscopic herniorrhaphy was performed to repair the inguinal hernia and to confirm the contents of cystic lesion. The hernia sac filled with mucinous contents. Pathological examination revealed that inflammatory granuloma due to numerous lipid droplets and phagocytic images of leukocytes in the hernia capsule. DISCUSSION AND CONCLUSION Although oil contrast medium is safety agent, there is rear complication which need the surgical treatment. Complete resection of granuloma, including hernia sac, is important to prevent recurrence.

[PMID: 31177157 DOI: 10.21873/anticanres.13448] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2019] [Revised: 04/30/2019] [Accepted: 05/02/2019] [Indexed: 12/21/2022]
Abstract
BACKGROUND/AIM The aim of the current study was to investigate the impact of the preoperative red cell distribution width (RDW) value on the overall survival (OS) and cancer-specific survival (CSS) of gastric cancer patients. PATIENTS AND METHODS A total of 366 gastric cancer patients who underwent curative gastrectomy were retrospectively reviewed. Among them, RDW was evaluated in 165 non-elderly and 201 elderly patients. RESULTS Multivariate analysis revealed that pathological stage (pStage), RDW, and carcinoembryonic antigen (CEA), were independent prognostic factors of OS, while pStage and RDW were independent prognostic factors of CSS. In non-elderly patients, based on the multivariate analysis, pStage, adjuvant chemotherapy, and RDW were identified as independent prognostic factors of OS. In elderly patients, RDW was identified as independent prognostic factors of OS and CSS. CONCLUSION Preoperative RDW is a promising independent prognostic factor in gastric cancer.

Abstract
Background The purpose of the present study is to investigate the utility of prognostic nutritional index (PNI) as a simple and readily available marker in esophageal squamous cell carcinoma (ESCC). Methods We retrospectively analyzed 169 patients who underwent potentially curative esophagectomy, for histologically verified ESCC. We decided to set the optimal cutoff value for preoperative PNI levels at 49.2, based on the cancer-specific survival (CSS) and the overall survival (OS) by receiver operating characteristic curve analysis. Results Multivariate logistic regression analysis identified that TNM pStage III [hazard ratio (HR) 3.261, p < 0.0001] and PNI < 49.2 (HR 3.887, p < 0.0001) were confirmed as independent poor predictive factors for CSS, and age >70 (HR 2.024, p < 0.0042), TNM pStage III (HR 2.510, p = 0.0002), and PNI < 49.2 (HR 2.248, p = 0.0013) were confirmed as independent poor predictive factors for OS. In non-elderly patients, TNM pStage III (CSS; HR 3.488, p < 0.0001, OS; HR 2.615, p = 0.0007) and PNI < 49.2 (CSS; HR 3.849, p < 0.0001, OS; HR 2.275, p = 0.001) were confirmed as independent poor predictive factors for CSS, and OS when multivariate logistic regression analysis was applied. But in elderly patients, univariate analyses demonstrated that the TNM pStage III was the only significant risk factor for CSS (HR 3.701, p = 0.0057) and OS (HR 1.974, p = 0.0224). Conclusions The PNI was a significant and independent predictor of CSS and OS of ESCC patients after curative esophagectomy. The PNI was cost-effective and readily available, and it could act as a marker of survival.

Abstract
Background We describe a novel scoring system, namely the inflammatory response biomarker (IRB) score. The aim of this study is to evaluate the clinical value of IRB score in patients undergoing curative resection for esophageal squamous cell carcinoma (SCC). Methods We retrospectively reviewed patients who underwent curative esophagectomy. We evaluated IRB score in both non-elderly (<70 years) and elderly (≥70 years) SCC patients. The IRB score was determined as follows: a high lymphocyte-to-monocyte ratio (LMR) (>4), a high neutrophil-to-lymphocyte ratio (NLR) (>1.6), and a low platelet-to-lymphocyte ratio (PLR) (<147) were each scored as 1, and the remaining values were scored as 0; the individual scores were then summed to produce the IRB score (range 0−3). Results Univariate analyses demonstrated that the TNM pStage (p < 0.0001), tumor size (p = 0.002), LMR (p = 0.0057), PLR (p = 0.0328) and IRB score (p = 0.0003) were significant risk factors for a worse prognosis. On multivariate analysis, the TNM pStage (p < 0.0001) and IRB score (p = 0.0227) were independently associated with worse prognosis in overall patients. Among non-elderly patients, multivariate analyses demonstrated that the pStage (p = 0.0015) and IRB score (p = 0.0356) were independent risk factors for a worse prognosis. Among elderly patients, multivariate analysis demonstrated that the pStage (p = 0.0016), and IRB score (p = 0.0102) were independent risk factors for a worse prognosis. Conclusion The present study provides evidence that the preoperative IRB score can be considered a promising independent prognostic factor of cancer-specific survival in patients undergoing curative resection for SCC, and that its predictive ability is useful in both non-elderly and elderly patients.

Prognostic significance of red cell distribution width in esophageal squamous cell carcinoma. J Surg Res 2018; 230:53-60. [PMID: 30100040 DOI: 10.1016/j.jss.2018.04.051] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2017] [Revised: 04/11/2018] [Accepted: 04/19/2018] [Indexed: 11/16/2022]
Abstract
BACKGROUND Red cell distribution width (RDW) is routinely assessed as part of the complete blood count (CBC) to gather information on the heterogeneity in the size of circulating erythrocytes. RDW is a more sensitive screening marker for anemia, inflammation, and nutritional deficiencies. The purpose of this study was to explore the prognostic value of RDW in esophageal squamous cell carcinoma (ESCC) patients. METHODS We conducted a retrospective study of data from 148 ESCC consecutive patients who underwent potentially curative esophagectomy and analyzed the correlation of RDW with various clinicopathological factors. RESULTS Multivariate analyses identified a high RDW (HR, 2.061; P = 0.0286) as a significant risk factor for cancer-specific survival (CSS). Kaplan-Meier analysis and the log-rank test demonstrated that patients with a high RDW had a significantly worse prognosis in terms of CSS than those with a low RDW (P = 0.0011). In multivariate analysis, there was no significant relationship between RDW and CSS in pathological tumor node metastasis stage I or II patients. However, a high RDW (HR, 2.386; P = 0.0471) was confirmed to be an independent worse prognostic factor for CSS in pathological tumor node metastasis stage III cancer patients. Kaplan-Meier analysis and the log-rank test showed a significant relationship between RDW and CSS in patients with pathological tumor node metastasis stage III (P = 0.0175). CONCLUSIONS The RDW was a significant and independent predictor of poor survival in ESCC patients after curative esophagectomy. RDW may aid clinicians in detecting signs of recurrence very early and effectively customize treatment regimens. RDW is thus a convenient, cost-effective, and readily available biomarker to predict survival in ESCC.

Abstract
BACKGROUND/AIM Recent evidence suggests that preoperative malnutrition may lead to poor survival in cancer patients. This study aimed to determine the ability of the prognostic nutritional index (PNI) to predict survival in gastric cancer patients. PATIENTS AND METHODS Two hundred and eighteen patients who had undergone laparoscopic gastrectomy were retrospectively reviewed via propensity score-matched analysis. RESULTS In multivariate analysis of overall patients, pTNM stage, carcinoembryonic antigen, and PNI were independent predictors of overall survival (OS), and pTNM stage and PNI were independent predictors of cancer-specific survival (CSS). Among the 92 non-elderly patients, pTNM stage and PNI were independent predictors of OS, and pTNM stage, PNI, and adjuvant chemotherapy were independent predictors of CSS in multivariate analysis. On the other hand, among the 126 elderly patients, low PNI value was identified as a significant predictor of shorter OS in univariate analysis. CONCLUSION PNI is associated with OS and CSS in gastric cancer patients, especially non-elderly patients.

Concurrent Chemoradiotherapy with Docetaxel, Cisplatin, and 5-fluorouracil Improves Survival of Patients with Advanced Esophageal Cancer Compared with Conventional Concurrent Chemoradiotherapy with Cisplatin and 5-fluorouracil. J Cancer 2018; 9:2765-2772. [PMID: 30123343 PMCID: PMC6096357 DOI: 10.7150/jca.23456] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2017] [Accepted: 05/15/2018] [Indexed: 12/12/2022] Open
Abstract
Purpose: To compare treatment outcomes and adverse events between concurrent chemoradiotherapy with docetaxel, cisplatin, and 5-fluorouracil (DCF-RT) and conventional concurrent chemoradiotherapy with cisplatin and 5-fluorouracil (CF-RT). Methods and Materials: We retrospectively investigated treatment outcomes and adverse events in 121 patients with advanced esophageal cancer who underwent concurrent chemoradiotherapy with CF-RT (n = 83) or DCF-RT (n = 38). In the CF-RT group, patients were administered cisplatin (70 mg/m2) and 5-fluorouracil (700 mg/m2) for 5 days; in the DCF-RT group, patients were administered docetaxel (50 mg/m2), cisplatin (50 mg/m2), and 5-fluorouracil (500 mg/m2) for 5 days. The radiotherapy dose was 1.8-2 Gy per session, up to a total of 50-60 Gy. Results: The complete response (CR) rate was 37.8% in the CF-RT group and 52.6% in the DCF-RT group. Overall survival (OS) rates at 2 and 3 years were 45.0% and 37.5%, respectively, in the CF-RT group and 62.9% and 56.7%, respectively, in the DCF-RT group, with a significant intergroup difference (p = 0.032). Progression-free survival rates at 2 and 3 years were 44.1% and 36.9%, respectively, in the CF-RT group and 45.0% and 45.0%, respectively, in the DCF-RT group (p = 0.10). Local control rates at 2 and 3 years were 59.1% and 54.6%, respectively, in the CF-RT group and 71.8% and 71.8%, respectively, in the DCF-RT group (p = 0.12). The incidence of Grade 3/4 leukopenia was 55.4% (n = 46) in the CF-RT group and 78.9% (n = 30) in the DCF-RT group, with a significant intergroup difference (p = 0.022). The incidence of Grade 3/4 neutropenia was 47.0% (n = 39) in the CF-RT group and 65.8% (n = 25) in the DCF-RT group, with a notable albeit not statistically significant difference between the groups (p = 0.054). There were no significant intergroup differences in anemia, thrombocytopenia, radiation-induced dermatitis, radiation esophagitis, or late adverse events. Conclusions: Rates of OS and CR were improved after treatment with DCF-RT compared with CF-RT. Although DCF-RT-treated patients had higher rates of leukopenia, treatment safety was ensured through proper management of myelotoxicity. DCF-RT is a promising treatment regimen for advanced esophageal cancer.

Complete abdominal wound and anastomotic leak with diffuse peritonitis closure achieved by an abdominal vacuum sealing drainage in a critical ill patient: a case report. BMC Surg 2018; 18:41. [PMID: 29907107 PMCID: PMC6003133 DOI: 10.1186/s12893-018-0375-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2018] [Accepted: 06/05/2018] [Indexed: 02/07/2023] Open
Abstract
Background Negative pressure wound therapy (NPWT) is a widely accepted technique to treat local infectious wounds of the skin, subcutaneous tissue, fascia, or muscle. Recently, several reports describing the efficacy of NPWT for various types of fistulas and anastomotic leaks have been published. We herein describe a patient with an open abdominal wound due to colonic anastomotic leakage and diffuse peritonitis, in whom abdominal vacuum sealing (AVS) as a modified NPWT was useful for the management of this complex wound. Case presentation A 32-year-old man was admitted to our hospital with late presenting traumatic diaphragmatic hernia and strangulated ileum complicated by necrosis of the ileum and transverse colon. He had a history of cervical spinal cord injury due to suicide attempt 14 years earlier and, as a result of cervical spinal cord injury, he was paralyzed in the lower body. The patient underwent an urgent hernia repair and bowel resection. Postoperatively, he developed severe septic shock. On postoperative day (POD) 6, wound dehiscence due to colonic anastomotic leakage with diffuse peritonitis was diagnosed, but he was unable to undergo re-operation because of refractory severe septic shock combined with neurogenic shock due to the cervical cord injury. The patient was treated with AVS therapy. He gradually recovered from septic shock, and the anastomotic leakage healed after a 2-month period. The wound dehiscence was also reduced. The patient resumed oral intake on POD 112 and was discharged on POD 190. Conclusions Although surgical repair would be the best method for the treatment of diffuse peritonitis due to gastrointestinal perforation or anastomotic leakage, our case suggests that AVS with ‘conventional’ drainage is a treatment of choice for open abdominal wounds even in the presence of diffuse peritonitis caused by intestinal anastomotic leakage, especially in patients with poor general medical condition.

Bevacizumab-induced intestinal perforation in a patient with inoperable breast cancer: a case report and review of the literature. J Med Case Rep 2018; 12:84. [PMID: 29580267 PMCID: PMC5870367 DOI: 10.1186/s13256-018-1619-x] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2017] [Accepted: 02/16/2018] [Indexed: 11/25/2022] Open
Abstract
Background Gastrointestinal perforation is known as a serious adverse event, but, for breast cancer, there are very few reports of gastrointestinal perforation. This report highlights gastrointestinal perforation caused by bevacizumab for breast cancer, which is of special interest because gastrointestinal perforations caused by bevacizumab are very rare in breast cancer. Case presentation We describe the case of 54-year-old Japanese woman. She was diagnosed as having inoperable breast cancer T2 N1 M1 (pleura, peritoneum), Stage IV, and received chemotherapy by paclitaxel. There was reduction in the primary tumor and disappearance of the pleural effusion; however, the ascites did not change. We performed diagnostic laparoscopy which revealed that her whole peritoneum was thickened, and her small intestine, colon, and her omentum were grouped and formed an omental cake. We submitted a part of her peritoneum to pathological examination and diagnosed the peritoneum dissemination of breast cancer. On the basis of these results, paclitaxel and bevacizumab combination chemotherapy was started, and a decrease in ascites was seen. However, a gastrointestinal perforation occurred on 26th day of second cycle of bevacizumab + paclitaxel, and we performed an emergency operation. In the operation, the omental cake was resolved, and we could search the full length of the gastrointestinal tract. Two small perforations of her small intestine were seen. We performed simple closures for perforations, and peritoneal lavage and drainage. She was in a state of septic shock, but it improved. It was thought that the small intestinal perforations were caused by the bevacizumab-additional chemotherapy which was very effective. Conclusions We report a very rare and valuable case. This case suggests that the risk of gastrointestinal perforation must be considered in a case of bevacizumab administration, and it is necessary to determine carefully the patient administered bevacizumab, regardless of the type of cancer.

Abstract
Background An ideal tumor marker should be capable of being detected at any stage of the disease. However, gastric cancer patients do not always have elevated serum carcinoembryonic antigen (CEA) levels, even in advanced cases. Recently, several studies have investigated the associations between preoperative PNI and postoperative long-term outcomes. In this study, we focused on the significance of the prognostic nutritional index (PNI) as a potential predictor of survival in resectable gastric cancer patients with normal preoperative serum CEA levels. Methods We retrospectively conducted cohort study to evaluate the PNI as a predictor of survival in 368 resectable gastric cancer patients who underwent potentially curative gastrectomy at our institute between January 2010 and December 2016. We selected 218 patients by propensity score matching to reduce biases due to the different distributions of co-variables among the comparable groups. Results In the multivariate analysis, pStage (hazard ratio [HR]: 14.003, 95% confidence interval [CI]: 5.033–44.487; p < 0.001), PNI (HR: 2.794, 95% CI: 1.352–6.039; p < 0.001) were identified as independent prognostic factors of CSS in 218 propensity matched gastric cancer patients. The Kaplan-Meier analysis demonstrated that low PNI patients had a significantly poorer cancer specific survival (CSS) than high PNI patients (p = 0.008). Among 166 propensity matched gastric cancer patients with normal preoperative serum CEA levels, multivariate analysis demonstrated that pStage (HR: 7.803, 95% CI: 3.015–24.041; p < 0.001) and PNI (HR: 3.078, 95% CI: 1.232–8.707; p = 0.016) were identified as independent prognostic factors of CSS. And Kaplan-Meier analysis demonstrated that low PNI had a significantly poorer CSS than high PNI value (p = 0.011). Conclusions This study demonstrates that a low preoperative PNI value is a potential independent risk factor for poorer CSS in patients with gastric cancer, even in those with normal serum CEA levels.

Abstract
A 60s-year-old Japanese male underwent curative resection for an advanced adenocarcinoma of the esophagogastric junction(Stage III C), followed by adjuvant chemotherapy.Twenty -one months later, he was admitted to our hospital with a complaint of marked decline in activities of daily living(ADL).The patient was diagnosed with pancytopenia, disseminated intravascular coagulation(DIC), multiple lymph node and bone metastases, and bone marrow carcinomatosis.After completing a sufficient informed consent process, he received chemotherapy along with blood transfusion, and then DIC, pancytopenia, and ADL of the patient improved.However, the lack of response of pancytopenia and DIC to transfusion relapsed and his ADL worsened after the second course of chemotherapy.It was difficult to administer additional chemotherapy in the patient and he died 24 months after surgery.There is no established treatment for disseminated carcinomatosis of the bone marrow, and the prognosis of these patients without treatment is reported to be only one month.Our case with prolonged survival following chemotherapy and blood transfusion may support the clinical usefulness of chemotherapy for bone marrow carcinomatosis from esophagogastric junctional carcinoma.

Abstract
A 27-year-old man with recurrent right lower quadrant pain was admitted to our hospital. Ultrasonography and computed tomography examination of the abdomen revealed a target sign in the ascending colon, which was compatible with the diagnosis of cecal intussusception. The intussusception was spontaneously resolved at that time, but it relapsed 6 mo later. The patient underwent a successful colonoscopic disinvagination; there was no evidence of neoplastic or inflammatory lesions in the colon and terminal ileum. The patient underwent laparoscopic surgery for recurring cecal intussusception. During laparoscopy, we observed an unfixed cecum on the posterior peritoneum (i.e. a mobile cecum). Thus, we performed laparoscopic appendectomy and cecopexy with a lateral peritoneal flap using a barbed wound suture device. The patient’s post-operative course was uneventful, and he continued to do well without recurrence at 10 mo after surgery. Laparoscopic cecopexy using a barbed wound suture device is a simple and reliable procedure that can be the treatment of choice for recurrent cecal intussusception associated with a mobile cecum.

Abstract
Background Systemic inflammatory markers, including the lymphocyte-to-monocyte ratio, neutrophil-to-lymphocyte ratio, and platelet-to-lymphocyte ratio have been shown to predict postoperative recurrence and survival in various types of cancer. However, their role in esophageal cancer has yet to be determined. This study aimed to evaluate the prognostic significance of an inflammatory response biomarker (IRB) score, independent of conventional clinicopathological criteria, in patients with esophageal cancer undergoing curative resection. Patients and methods We retrospectively reviewed a database containing the medical records of 147 consecutive patients who underwent curative esophagectomy for esophageal squamous cell carcinoma. The IRB score was determined as follows: a low lymphocyte-to-monocyte ratio (<4), a low neutrophil-to-lymphocyte ratio (<1.6), and a high platelet-to-lymphocyte ratio (>147), which were each scored as 1, with all remaining values scored as 0. The scores were added together to produce the IRB score (range: 0–3). Results An IRB score of 2–3 (hazard ratio: 6.023, 95% confidence interval: 1.675–13.078; P<0.01) was identified as an independent poor prognostic factor of cancer-specific survival (CSS) in a multivariate logic regression analysis. The 5-year CSS rates in patients with the IRB scores of 0−1, 2, and 3 were 37.8%, 67.8%, and 72.5%, respectively. As determined by Kaplan–Meier analysis and the log-rank test, these differences were significant (P<0.001). Conclusion The IRB score can predict the systemic inflammatory response as accurately as conventional tumor markers and is useful for determining CSS in patients with esophageal cancer undergoing curative thoracoscopic esophagectomy.

Abstract
BACKGROUND Recent studies have revealed significant relationships between the lymphocyte-to-monocyte ratio (LMR), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) and survival in various cancers. The purpose of this study was to confirm whether the LMR, NLR, and PLR have prognostic values, independent of clinicopathological criteria, in patients undergoing curative resection for esophageal cancer. METHODS The LMR, NLR and PLR were calculated in 147 consecutive patients who underwent curative esophagectomy between January 2006 and December 2014. Receiver operating characteristics (ROC) curve analysis was conducted to identify the optimal cutoff values of each biomarkers. RESULTS In multivariate analysis for cancer-specific survival (CSS), pTNM stage (p < 0.0001) and low LMR (p = 0.0081) were selected as independent prognostic factor. Similarly, pTNM stage(p < 0.0001) and low LMR (p = 0.0225) were found to be independent prognostic factor for overall survival (OS). There was no significant relationship between LMR, NLR and PLR and survival in patients with stage I or II, however, significant relationships between LMR and CSS or OS were observed in patients with stage III esophageal cancer. CONCLUSIONS LMR can be used as a novel predictor of postoperative CSS and OS in patients with esophageal cancer and that it may be useful in identifying patients with a poor prognosis even after radical esophagectomy.

Prognostic value of preoperative inflammatory response biomarkers in patients with esophageal cancer who undergo a curative thoracoscopic esophagectomy. BMC Surg 2016; 16:66. [PMID: 27650456 PMCID: PMC5028997 DOI: 10.1186/s12893-016-0179-5] [Citation(s) in RCA: 34] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2016] [Accepted: 09/07/2016] [Indexed: 02/08/2023] Open
Abstract
Background Several inflammatory response biomarkers, including lymphocyte-to-monocyte ratio (LMR), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) have been reported to predict survival in various cancers. The aim of this study is to evaluate the clinical value of these biomarkers in patients undergoing curative resection for esophageal cancer. Methods The LMR, NLR and PLR were calculated in 147 consecutive patients who underwent esophagectomy between January 2006 and February 2015. We examined the prognostic significance of the LMR, NLR, and PLR in both elderly and non-elderly patients. We evaluated the cancer-specific survival (CSS), with the cause of death determined from the case notes or computerized records. Results Univariate analyses demonstrated that TNM pStage (p < 0.0001), tumor size (p = 0.0014), operation time (p = 0.0209), low LMR (p = 0.0008), and high PLR (p = 0.0232) were significant risk factors for poor prognosis. Meanwhile, TNM pStage (p < 0.0001) and low LMR (p = 0.0129) were found to be independently associated with poor prognosis via multivariate analysis. In non-elderly patients, univariate analyses demonstrated that TNM pStage (p < 0.0001), tumor size (p = 0.0001), operation time (p = 0.0374), LMR (p < 0.0001), and PLR (p = 0.0189) were significantly associated with a poorer prognosis. Multivariate analysis demonstrated that TNM pStage (p = 0.001) and LMR (p = 0.0007) were independent risk factors for a poorer prognosis. In elderly patients, univariate analysis demonstrated that that TNM pStage (p = 0.0023) was the only significant risk factor for a poor prognosis. Conclusions LMR was associated with cancer-specific survival (CSS) of esophageal cancer patients after curative esophagectomy. In particular, a low LMR was a significant and independent predictor of poor survival in non-elderly patients. The LMR was convenient, cost effective, and readily available, and could thus act as markers of survival in esophageal cancer.

Significance of prophylactic intra-abdominal drain placement after laparoscopic distal gastrectomy for gastric cancer. World J Surg Oncol 2015; 13:181. [PMID: 25962503 PMCID: PMC4440503 DOI: 10.1186/s12957-015-0591-9] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2014] [Accepted: 04/24/2015] [Indexed: 12/14/2022] Open
Abstract
Background Unnecessary intra-abdominal drain insertion must be avoided, but little is known about the value of prophylactic drainage following laparoscopic distal gastrectomy (LDG). In this study, we investigated the significance of prophylactic drain placement after LDG for gastric cancer. Methods Seventy-eight consecutive patients with gastric cancer who underwent LDG in our department were retrospectively analyzed. The patients were divided into two groups according to the insertion of a prophylactic intra-abdominal drain following LDG. The ‘drain group’ comprised 45 patients with routine use of a prophylactic intra-abdominal drain, and the ‘no-drain group’ comprised 33 patients who did not undergo placement of an intra-abdominal drain. Results There were no significant differences in terms of the mean age of the patients, male/female ratio, body mass index, and concurrent diseases between the drain group and the no-drain group. In addition, there were no significant differences in the tumor location, tumor diameter, depth of the tumor, nodal metastasis, and tumor stage between the two groups. All patients in each group were successfully treated with R0 surgery, and no patient required conversion to open surgery. Surgery-related factors, including lymph node dissection and operative time, were similar in the drain group and the no-drain group. A comparison of the amount of intraoperative blood loss between patients with and without postoperative complications revealed that patients who experienced postoperative complications had a significantly larger amount of blood loss than those without postoperative complications. A comparison of operative times between patients with and without surgery-related postoperative local complications revealed that patients who experienced surgery-related postoperative local complications had a significantly longer operative time than those without surgery-related postoperative local complications. Analysis of operative times in each group revealed that patients with surgery-related postoperative local complications had a significantly longer operative time than those without surgery-related postoperative local complications in the no-drain group. Conclusions Intraoperative factors such as the operative time and the amount of intraoperative blood loss affected the occurrence of postoperative complications following LDG. A prophylactic drain may thus be useful in patients at higher risk and in those with a longer operative time or massive intraoperative bleeding.

Abstract
BACKGROUND Previously it has reported that the incidence of internal hernia can be decreased by closing Petersen's defect, but the perfect closure method, in fact, has not been discovered yet. In this study we have developed an easy and reliable method for closing Petersen's defect in the Roux-en-Y reconstruction after a laparoscopic distal gastrectomy. MATERIALS AND METHODS We performed intracorporeal Roux-en-Y reconstruction after laparoscopic distal gastrectomy with antiperistaltic gastrojejunostomy. The greater omentum is placed on the cranial side of the transverse colon through the defect between the elevated jejunum and the transverse mesocolon. Anastomosis is performed of the transverse mesocolon attached to the transverse colon, the greater omentum is passed through the Petersen's defect, and the stump of the mesojejunum is attached to the elevated jejunum by an interrupted suture. Petersen's defect is spread and straightened to stabilize the visual field. The thread is inserted first at the base of the stump of the elevated mesojejunum, next to the greater omentum, which has passed through Petersen's defect, and then to the transverse mesocolon to set the starting point of continuous suture. The stitches of continuous suture are sewn toward the transverse colon. Petersen's defect is closed completely. RESULTS We performed this technique in 37 patients. All procedures were completed without intraoperative complication or conversion to laparotomy. During the follow-up period, none of the patients developed complications related to the internal hernia, such as Petersen's hernia. CONCLUSIONS We have indicated a novel, easy, and secure closure procedure of Petersen's defect following laparoscopic distal gastrectomy with Roux-en-Y reconstruction.

A novel technique to minimize deformation of the stomach in laparoscopic partial gastrectomy for intraluminal gastric GISTs. J Laparoendosc Adv Surg Tech A 2014; 24:707-11.

Abstract
BACKGROUND The laparoscopic approach would be difficult to perform without causing deformation of the stomach in managing gastrointestinal stromal tumors (GISTs) of the intraluminal type, especially in those that are located in the posterior gastric wall or around the gastroesophageal junction and the pylorus, because intraluminal GISTs usually require an excessive resection of the gastric wall for cure. We present a novel surgical technique for successful management of intraluminal gastric GISTs that minimizes deformation of the stomach regardless of tumor location. MATERIALS AND METHODS The operating surgeon handles the tumor by holding tissue surrounding the tumor and performs seromyotomy using an ultrasonically activated device along the outer edge of the tumor. The tumor gradually protrudes like an extraluminal tumor as the seromyotomy proceeds. When seromyotomy along the tumor comes up to the point where the tumor sufficiently turns over the gastric serosa, the tumor looks like a pedunculated extraluminal GIST. Two seromuscular sutures are applied to close the exfoliated seromuscular layer. The tips of two seromuscular sutures are held and then pulled up toward the ventral side so that the staple line is aligned in line with the minor axis of the stomach. Finally, complete tumor removal with minimal seromuscular resection is accomplished by applying a linear stapler. RESULTS All patients resumed oral ingestion on the day after surgery and showed no signs of anastomotic constriction or obstruction. CONCLUSIONS Our laparoscopic procedure for gastric GISTs is simple and allows us easy and precise removal of the tumor and closure of the gastric wall with minimum necessary resection, regardless of the location and growth form of the tumors.
