The efficacy of simple oral nutritional supplements versus usual care in postoperative patients with gastric cancer: study protocol for a multicenter, open-label, parallel, randomized controlled trial.

BACKGROUND: Body weight loss (BWL) after gastrectomy impact on the short- and long-term outcomes. Oral nutritional supplement (ONS) has potential to prevent BWL in patients after gastrectomy. However, there is no consistent evidence supporting the beneficial effects of ONS on BWL, muscle strength and health-related quality of life (HRQoL). This study aimed to evaluate the effects of ONS formulated primarily with carbohydrate and protein on BWL, muscle strength, and HRQoL. METHODS: This will be a multicenter, open-label, parallel, randomized controlled trial in patients with gastric cancer who will undergo gastrectomy. A total of 120 patients who will undergo gastrectomy will be randomly assigned to the ONS group or usual care (control) group in a 1:1 ratio. The stratification factors will be the clinical stage (I or ≥ II) and surgical procedures (total gastrectomy or other procedure). In the ONS group, the patients will receive 400 kcal (400 ml)/day of ONS from postoperative day 5 to 7, and the intervention will continue postoperatively for 8 weeks. The control group patients will be given a regular diet. The primary outcome will be the percentage of BWL (%BWL) from baseline to 8 weeks postoperatively. The secondary outcomes will be muscle strength (handgrip strength), HRQoL (EORTC QLQ-C30, QLQ-OG25, EQ-5D-5L), nutritional status (hemoglobin, lymphocyte count, albumin), and dietary intake. All analyses will be performed on an intention-to-treat basis. DISCUSSION: This study will provide evidence showing whether or not ONS with simple nutritional ingredients can improve patient adherence and HRQoL by reducing BWL after gastrectomy. If supported by the study results, nutritional support with simple nutrients will be recommended to patients after gastrectomy for gastric cancer.

A case of laparoscopic lymphadenectomy for adenocarcinoma of unknown primary incidentally detected as a solitary enlarged lymph node along the common hepatic artery.

BACKGROUND: Even in cancer of unknown primary (CUP), which is rare clinical condition, solitary anterosuperior lymph node (LN) along the common hepatic artery (No.8a LN) enlargement diagnosed as metastatic adenocarcinoma has never been reported. CASE PRESENTATION: A 68-year-old Japanese male, with a history of early gastric cancer that had been completely treated by endoscopic submucosal dissection 26 years ago, was detected a single enlarged nodule along the common hepatic artery, No.8a LN, incidentally by computed tomography performed for monitoring of interstitial pneumonia. Endoscopic ultra-sound-guided fine needle aspiration revealed that this nodule was adenocarcinoma suggestive of metastasis, but other imaging studies, including upper and lower gastrointestinal endoscopy, positron emission tomography, and ultrasonography did not detect any primary cancer. We have finally diagnosed as the LN metastasis of CUP and performed laparoscopic lymphadenectomy for this tumor. The tumor was approximately 5 cm in size, was in close proximity to the pancreas, and involved part of the right gastric artery and vein. LNs in the No.5 and No.8a areas, including this tumor, were dissected laparoscopically, and radical resection was achieved. The patient had no postoperative complication and was discharged on postoperative day 10. Immunohistopathological findings revealed that the tumor was poorly differentiated adenocarcinoma, and different from the histology of gastric cancer resected 26 years ago, although the tumor was suggestive of gastrointestinal origin. Imaging studies performed 2 and 6 months after discharge also did not reveal a primary site. CONCLUSION: We reported a case of solitary No.8a LN adenocarcinoma of CUP. For diagnostic and therapeutic purposes, radical resection is recommended for single enlarged intra-abdominal LN of CUP.

Utility of articulating instruments as an alternative to robotic devices in laparoscopic right hemicolectomy.

Laparoscopic complete mesocolic excision with central vessel ligation has been widely accepted for its oncological benefits in colon cancer surgery. However, laparoscopic right hemicolectomy involves a risk for vascular injury during dissection around the surgical trunk. This technical difficulty has been attributed to the limited movement of conventional laparoscopic forceps. Although robotic devices can overcome the restricted motion of laparoscopic devices, they are not yet widely used. The ArtiSential is an articulating laparoscopic instrument that has a two-joint end-effector that enables a wide range of motion precisely reflecting the surgeon's finger movements, and is designed to compensate for the drawbacks of conventional laparoscopic tools. The present study demonstrated the utility of articulating instruments in laparoscopic right hemicolectomy by comparing the authors' laparoscopic procedures, using articulating instruments, with robotic procedures. Articulating laparoscopic instruments can be successfully maneuvered in virtually the same manner as robotic devices and, as such, represent a viable alternative to robotic surgery.

Anterior versus posterior mediastinal reconstruction after esophagectomy in esophageal cancer patients: a systematic review and meta-analysis.

PURPOSE: Esophagectomy is the primary surgical treatment for esophageal cancer, although other treatment approaches are often incorporated, including preoperative chemotherapy and chemoradiotherapy. The two major routes of esophageal reconstruction after esophagectomy are the anterior mediastinal (retrosternal, heterotopic) and posterior mediastinal (prevertebral, orthotopic) routes. However, which of these two routes of reconstruction is the most appropriate remains controversial. This systematic review aimed to compare the efficacy and safety of anterior mediastinal reconstruction with those of posterior mediastinal reconstruction after esophagectomy in esophageal cancer. METHODS: In January 2022, a literature search of the CENTRAL, MEDLINE, and EMBASE databases was conducted to identify all published and unpublished randomized controlled trials, regardless of language. Eight studies were included for quantitative synthesis. RESULTS: Postoperative death (9/129 and 4/125, risk ratio [RR]: 2.07, 95% confidence interval [CI]: 0.65-6.64) and incidence of anastomotic leak (24/208 and 26/208, RR: 0.95, 95% CI: 0.56-1.62) were not significantly different between the two mediastinal reconstructions. We could not perform a meta-analysis for quality of life, loss of body weight, or postoperative hospital stay due to data limitations. CONCLUSION: Overall, there was low-quality evidence to suggest that the outcomes of the anterior and posterior mediastinal routes of reconstruction are not significantly different in patients with esophageal cancer.

Impact of the coronavirus disease 2019 pandemic on gastric and colorectal cancer surgeries: a multicenter epidemiologic study from the Kinki region of Japan.

The coronavirus disease 2019 pandemic affected cancer surgeries and advanced cancer diagnoses; however, the trends in patient characteristics in medical institutions during this time, and the surgical approaches used are unclear. We investigated the impact of the pandemic on gastric and colorectal cancer surgeries in the Kinki region of Japan. We grouped 1688 gastric and 3493 colorectal cancer surgeries into three periods: "pre-pandemic" (April 2019-March 2020), "pandemic 1" (April 2020-March 2021), and "pandemic 2" (April 2021-September 2021), to investigate changes in the number of surgeries, patient characteristics, surgical approaches, and cancer progression after surgery. Gastric and colorectal cancer surgeries decreased from the pre-pandemic levels, by 20% and 4%, respectively, in pandemic 1, and by 31% and 19%, respectively, in pandemic 2. This decrease had not recovered to pre-pandemic levels by September, 2021. Patient characteristics, surgical approaches, and cancer progression of gastric and colorectal surgeries did not change remarkably as a result of the coronavirus disease 2019 pandemic.

Total gastrectomy as a risk factor for postoperative loss of skeletal muscle in minimally invasive surgery for patients with gastric cancer.

PURPOSE: Loss of skeletal muscle mass after gastrectomy for gastric cancer leads to decreased quality of life and poor postoperative survival. However, few studies have examined the postoperative loss of skeletal muscle mass following minimally invasive gastrectomy. This study investigated the impact of minimally invasive total gastrectomy (MI-TG) on changes in skeletal muscle mass during the early postoperative period. METHODS: Patients who underwent MI-TG or minimally invasive distal or proximal gastrectomy (MI-nonTG) for cStage I-III gastric cancer were retrospectively analyzed (n = 58 vs. 182). Their body composition was measured before surgery and 2 months after surgery. Multivariable linear regression analysis was performed to clarify the impact of the surgical procedure on skeletal muscle index changes using clinically relevant covariates. RESULTS: Skeletal muscle mass decreased more in the MI-TG group than in the MI-nonTG group (median [interquartile range]; -5.9% [-10.6, -3.7] vs -4.5% [-7.3, -1.9], P = 0.004). In multivariable linear regression analysis using clinically relevant covariates, MI-TG was an independent risk factor for postoperative loss of skeletal muscle mass (coefficient - 2.6%, 95% CI -4.5 to -0.68, P = 0.008). CONCLUSIONS: Total gastrectomy was a risk factor for loss of skeletal muscle mass during the early postoperative period. If oncologically feasible, proximal or distal gastrectomy with a small remnant stomach should be considered.

Total pelvic exenteration for mucinous adenocarcinoma arising from an implantation cyst 26 years after surgery for rectal cancer.

A 47-year-old man underwent low anterior resection for rectal cancer and was surveilled for 5 years without metastasis. Twenty-four years later, the patient developed an implantation cyst at the anastomotic site. Two years after the diagnosis, colonoscopy revealed a disintegrated area in the lesion, and pathological examination of the biopsy specimen revealed adenocarcinoma. Due to the suspicion of invasion into the surrounding organs, the patient underwent laparoscopic total pelvic exenteration after neoadjuvant chemoradiotherapy. A transabdominal and transperineal endoscopic approach was used for safe en bloc excision of the tumor. Pathological examination of the specimen confirmed mucinous adenocarcinoma arising from the implantation cyst. Although an implantation cyst is considered benign, it is important to suspect malignant transformation when its appearance changes. For the accurate diagnosis of implantation cysts, surgeons, endoscopists, and radiologists should be aware of this disease.

Big insulin-like growth factor 2-producing multiple solitary fibrous tumors treated with debulking surgery: A case report.

Background: Non-islet cell tumor hypoglycemia (NICTH) is a rare paraneoplastic syndrome caused by a tumor-producing high molecular weight form of insulin-like growth factor 2 (IGF2) known as big IGF2. The only curative treatment for this condition is surgical resection of the responsible tumors. However, this may not be feasible in cases with multiple metastases at diagnosis of NICTH, and no standard treatment strategy for multiple tumors has been established. The effects of pharmacological therapies including somatostatin analogs are often inefficient and remain difficult to predict. Case description: A 68-year-old man was admitted to our hospital due to impaired consciousness and severe hypoglycemia. His medical history included diagnosis of a left temporal solitary fibrous tumor (SFT) at the age of 48 years, after which local recurrent and metastatic tumors were repeatedly resected. Four years before admission, multiple intraabdominal and subcutaneous tumors were detected and, being asymptomatic, were managed conservatively. Laboratory exam on admission demonstrated hypoglycemia accompanied with low serum insulin and IGF1 levels. Computed tomography (CT) scan revealed multiple intraabdominal and subcutaneous tumors increasing in size. Serum big IGF2 was detected on immunoblot analysis, and he was diagnosed as NICTH. In addition, tumor uptake was observed on 68Ga-labelled 1,4,7,10-tetraazacyclododecane-N,N',N'',N'''-tetraacetic acid-d-Phe1-Tyr3-octreotide positron emission tomography/CT (DOTATOC-PET/CT). Since larger tumor is more suspicious about responsible producibility of big IGF2, we planned to resect large ones preferentially and reduce the amounts of residual tumors. Debulking surgery was performed by removing eleven intraabdominal tumors; the hypoglycemia was then completely corrected. Histological analyses revealed the resected tumors to be metastases of SFT having somatostatin receptor 2 expression. In immunoblot analysis, the resected tumors were found to be positive for big IGF2; serum big IGF2 was undetectable after surgery. Conclusion: We present a case of NICTH with multiple metastatic SFTs. We strategically performed debulking surgery, which led to remission of hypoglycemia. This result demonstrates a pioneering practical solution for NICTH cases with multiple tumors. In addition, in cases of SFTs presenting with NICTH, positivity of DOTATOC-PET/CT as well as single-dose administration of octreotide may be predictive of the efficacy of somatostatin-based therapy.

Comparison of Minimally Invasive Surgery with Open Surgery for Remnant Gastric Cancer: A Multi-institutional Cohort Study.

BACKGROUND: Despite growing evidence of the effectiveness of minimally invasive surgery (MIS) for primary gastric cancer, MIS for remnant gastric cancer (RGC) remains controversial due to the rarity of the disease. This study aimed to evaluate the surgical and oncological outcomes of MIS for radical resection of RGC. PATIENTS AND METHODS: Patients with RGC who underwent surgery between 2005 and 2020 at 17 institutions were included, and a propensity score matching analysis was performed to compare the short- and long-term outcomes of MIS with open surgery. RESULTS: A total of 327 patients were included in this study and 186 patients were analyzed after matching. The risk ratios for overall and severe complications were 0.76 [95% confidence interval (CI): 0.45, 1.27] and 0.65 (95% CI: 0.32, 1.29), respectively. The MIS group had significantly less blood loss [mean difference (MD), -409 mL; 95% CI: -538, -281] and a shorter hospital stay (MD, -6.5 days; 95% CI: -13.1, 0.1) than the open surgery group. The median follow-up duration of this cohort was 4.6 years, and the 3-year overall survival were 77.9% and 76.2% in the MIS and open surgery groups, respectively [hazard ratio (HR), 0.78; 95% CI: 0.45, 1.36]. The 3-year relapse-free survival were 71.9% and 62.2% in the MIS and open surgery groups, respectively (HR, 0.71; 95% CI: 0.44, 1.16). CONCLUSIONS: MIS for RGC showed favorable short- and long-term outcomes compared to open surgery. MIS is a promising option for radical surgery for RGC.

Single-incision laparoscopic partial cecectomy for appendiceal mucocele in a patient with porphyria photosensitivity.

Erythropoietic protoporphyria (EPP) is a rare hereditary subtype of cutaneous porphyria characterized by photosensitivity. Increased exposure to light irradiation may precipitate acute liver failure, and surgical light-induced intestinal burns and perforations are known to occur. We report a case of EPP in a patient who underwent laparoscopic partial cecectomy for appendiceal mucocele. A 55-year-old man with EPP was presented for treatment of appendiceal mucocele. A light test using two types of laparoscopes (Companies O and S) was performed preoperatively. Light from the laparoscope manufactured by Company O caused photosensitivity; this effect was not observed with light from the laparoscope manufactured by Company S. Therefore, we performed laparoscopic partial cecectomy through a single umbilical incision using the laparoscope from Company S. Except for the incision site, the patient's skin was completely covered using surgical drapes. No intra- or postoperative complications were observed. Histopathological examination of the resected specimen revealed a low-grade appendiceal mucinous neoplasm.

Prophylactic supraclavicular lymph node dissection for esophageal squamous cell carcinoma: a systematic review and meta-analysis.

The supraclavicular lymph nodes (SCLNs) have been regarded as regional nodes for esophageal squamous cell carcinoma (ESCC) in Japan and eastern Asian countries, whereas their involvement has been regarded as distant metastasis in Western countries. The importance of thorough dissection of the lymphatic chain along the recurrent laryngeal nerve, including the cervical paraesophageal nodes, has become well understood; therefore, the contemporary clinical question is whether prophylactic SCLN dissection (SLND) in addition to cervical paraesophageal node dissection is beneficial for patients with ESCC. We analyzed studies comparing esophagectomy with SLND vs. esophagectomy without SLND, in both of which cervical paraesophageal node dissection had been completed, based on a comprehensive literature search of the PubMed, Scopus, and Cochrane databases. Our meta-analysis focused on two long-term outcomes: 3-year and 5-year overall survival (OS) rates; and three short-term outcomes: pneumonia, recurrent nerve palsy, and anastomotic leakage. Four studies, with a collective total of 1584 patients were included in the review. No significant differences were found between esophagectomy with SLND vs. esophagectomy without SLND in the meta-analysis of both long-term (3-year and 5-year OS; risk ratio 1.09, 95% CI 0.94-1.26, P = 0.28, and risk ratio 1.14, 95% CI 0.96-1.35, P = 0.15, respectively) and short-term outcomes. Based on our analysis, no clear data support prophylactic SLND on the cervical paraesophageal node dissection.

A Simple Preparation Method of Gelatin Hydrogels Incorporating Cisplatin for Sustained Release.

The objective of this study was to develop a new preparation method for cisplatin (CDDP)-incorporated gelatin hydrogels without using chemical crosslinking nor a vacuum heating instrument for dehydrothermal crosslinking. By simply mixing CDDP and gelatin, CDDP-crosslinked gelatin hydrogels (CCGH) were prepared. CDDP functions as a crosslinking agent of gelatin to form the gelatin hydrogel. Simultaneously, CDDP is incorporated into the gelatin hydrogel as a controlled release carrier. CDDP's in vitro and in vivo anticancer efficacy after incorporation into CCGH was evaluated. In the in vitro system, the CDDP was released gradually due to CCGH degradation with an initial burst release of approximately 16%. CDDP metal-coordinated with the degraded fragment of gelatin was released from CCGH with maintaining the anticancer activity. After intraperitoneal administration of CCGH, CDDP was detected in the blood circulation while its toxicity was low. Following intraperitoneal administration of CCGH in a murine peritoneal dissemination model of human gastric cancer MKN45-Luc cell line, the survival time was significantly prolonged compared with free CDDP solution. It is concluded that CCGH prepared by the CDDP-based crosslinking of gelatin is an excellent sustained release system of CDDP to achieve superior anticancer effects with minimal side effects compared with free CDDP solution.

A case of long-term survival treated with three metastasectomies and two subsequent adjuvant nivolumab therapies for recurrent malignant melanoma of the esophagus.

BACKGROUND: The treatment strategy for metastatic lesions of primary malignant melanoma of the esophagus (PMME) is currently determined on a case-by-case basis, based on the National Comprehensive Cancer Network (NCCN) guidelines for cutaneous melanoma. The NCCN guidelines state that resection should be considered in patients with resectable metastatic recurrence. Herein, we report a case of long-term survival treated with three metastasectomies and two subsequent adjuvant nivolumab therapies for the metastatic recurrence of PMME. CASE PRESENTATION: A 65-year-old female patient with PMME underwent thoracoscopic subtotal esophagectomy, gastric tube reconstruction via the posterior mediastinal route, and cervical esophagogastric anastomosis. Histopathological examination of the resected specimen revealed that the tumor was PMME with tumor invasion into the muscularis propria and no lymph node metastasis. At the age of 68 years, she developed intestinal invagination due to jejunal metastasis of malignant melanoma and underwent resection of the jejunum. Histopathological examination of the resected specimen revealed two metastases of malignant melanoma in the jejunum and one metastasis to the mesenteric lymph node. At the age of 75 years, a recurrence of malignant melanoma was found in the cervical esophagus. She underwent thoracoscopic mobilization of the gastric tube and esophagus followed by cervical esophagectomy and reconstruction with a free jejunum flap. She received 24 courses of nivolumab therapy for 1 year as a postoperative adjuvant therapy. Subsequently, at the age of 78 years, an enlarged left cervical lymph node and a mass in the right lower lobe of the lung were found. She underwent left cervical lymph node dissection and thoracoscopic wedge resection of the right lung. Histopathological examination of the resected specimens revealed that both tumors were metastases of malignant melanoma. At age 79 years, she received eight courses of nivolumab therapy as a second postoperative adjuvant therapy, with no sign of recurrence in a 9-month follow-up period after the third metastasectomy. CONCLUSION: In cases of metastatic recurrence of PMME, aggressive resection of oligometastasis with postoperative adjuvant nivolumab therapy may result in long-term survival.

Second primary malignancies in patients with clinical T1bN0 esophageal squamous cell carcinoma after definitive therapies: supplementary analysis of the JCOG trial: JCOG0502.

BACKGROUND: Previous studies have suggested that patients with esophageal squamous cell carcinoma (ESCC) are still at a high risk of developing second primary malignancies (SPMs) after definitive therapies. We evaluated the development of SPMs and explored its risk factors in patients with clinical T1bN0 ESCC. METHODS: JCOG0502 prospectively compared esophagectomy with definitive chemo-radiotherapy for clinical T1bN0 ESCC. Here, we reviewed all JCOG0502 patients' data for SPMs and investigated the risk factors for SPMs using uni-variable and multivariable analyses by Fine and Gray model. RESULTS: Among 379 enrolled patients, 213 underwent esophagectomy and 166 received chemo-radiotherapy. Patient characteristics were male (85%); median age [63 (range 41-75) years; location of the primary tumor (upper/middle/lower thoracic esophagus, 11%/63%/27%, respectively]; alcohol consumption history (79%); smoking history (66%); prevalence of no/several/many/unknown Lugol-voiding lesions (LVLs) (45%/36%/8%/11%, respectively). In a median follow-up of 7.1 years, 118 SPMs occurred in 99 (26%) patients. Cumulative incidences of SPMs after 3, 5, and 10 years were 9%, 15%, and 36%, respectively. The most common primary tumor sites were the head and neck (35%), stomach (20%) and lungs (14%). In multivariable analyses, compared to no LVLs, several LVLs [hazard ratio (HR) 2.24, 95% confidential interval (CI) 1.32-3.81] and many LVLs (HR 2.88, 95% CI 1.27-6.52) were significantly associated with the development of SPMs. Sixteen patients died due to the SPMs. CONCLUSION: The incidence of SPMs was high. The presence of LVLs, which was a predictive factor for SPMs, may be useful for surveillance planning.

Safety assessment of robotic gastrectomy and analysis of surgical learning process: a multicenter cohort study.

BACKGROUND: The safety of robotic gastrectomy (RG) for gastric cancer in daily clinical settings and the process by which surgeons are introduced and taught RG remain unclear. This study aimed to evaluate the safety of RG in daily clinical practice and assess the learning process in surgeons introduced to RG. METHODS: Patients who underwent RG for gastric cancer at Kyoto University and 12 affiliated hospitals across Japan from January 2017 to October 2019 were included. Any morbidity with a Clavien-Dindo classification grade of II or higher was evaluated. Moreover, the influence of the surgeon's accumulated RG experience on surgical outcomes and surgeon-reported postoperative fatigue were assessed. RESULTS: A total of 336 patients were included in this study. No conversion to open or laparoscopic surgery and no in-hospital mortality were observed. Overall, 50 (14.9%) patients developed morbidity. During the study period, 14 surgeons were introduced to robotic procedures. The initial five cases had surprisingly lower incidence of morbidity compared to the following cases (odds ratio 0.29), although their operative time was longer (+ 74.2 min) and surgeon's fatigue scores were higher (+ 18.4 out of 100 in visual analog scale). CONCLUSIONS: RG was safely performed in actual clinical settings. Although the initial case series had longer operative time and promoted greater levels of surgeon fatigue compared to subsequent cases, our results suggested that RG had been introduced safely.

Clinical Benefits of Routine Feeding Jejunostomy Tube Placement in Patients Undergoing Esophagectomy.

BACKGROUND: Routine placement of a feeding jejunostomy tube (FJT) following esophagectomy remains controversial due to the risk of complications including small bowel obstruction (SBO). This study aimed to evaluate FJT placement following esophagectomy. METHODS: This retrospective cohort study included consecutive 229 patients undergoing thoracoscopic esophagectomy between January 2010 and June 2020. Short-term outcomes, postoperative nutritional status, incidence of SBO, and long-term outcomes were compared between patients according to FJT placement. RESULTS: The total operative duration was significantly longer in the FJT group compared to the no FJT group (P < 0.0001); however, no differences in overall or severe postoperative morbidity were observed. Body weight loss at discharge was significantly attenuated in patients with FJT (5% vs 7%, P = 0.001). Serum cholinesterase levels were significantly higher in patients with FJT (P = 0.002), while no difference was observed in serum albumin levels. At 6-month follow-up, no statistically significant differences were observed in serological markers or percentage body weight. The incidence of SBO was significantly higher in the FJT group (P = 0.006). The 5-year incidence of SBO was 12%. Patients in the FJT group had higher progression-free and overall survival compared to patients in the no FJT group (P = 0.041 and P = 0.033, respectively). A similar trend toward better survival in the FJT group was observed after propensity score matching. CONCLUSIONS: Routine placement of FJT significantly improves postoperative nutritional status and may contribute to improved long-term survival but is associated with increased long-term risk of SBO.

McKeown esophagectomy with concomitant median arcuate ligament release in a case of esophageal cancer with celiac artery stenosis.

BACKGROUND: The celiac artery stenosis due to compression by median arcuate ligament (MAL) has been reported in many cases of pancreaticoduodenectomy, but not in cases of esophagectomy. Recently, the celiac artery stenosis due to MAL or arteriosclerosis has been reported to be associated with the gastric tube necrosis or anastomotic leakage following Ivor-Lewis esophagectomy. Herein, we present the first reported case of esophageal cancer with celiac artery stenosis due to compression by the MAL successfully treated by McKeown esophagectomy and gastric tube reconstruction following prophylactic MAL release. CASE PRESENTATION: A 72-year-old female patient was referred to our department for esophagectomy. The patient had received two courses of neoadjuvant chemotherapy with 5-FU and cisplatin for T2N0M0 squamous cell carcinoma of the middle esophagus. Preoperative contrast-enhanced computed tomography (CECT) showed celiac artery stenosis due to compression by the MAL. The development of collateral arteries around the pancreatic head was observed without evidence of aneurysm formation. The patient reported no abdominal symptoms. After robot-assisted esophagectomy with mediastinal lymphadenectomy, gastric mobilization, supra-pancreatic lymphadenectomy, and preparation of the gastric tube were performed under laparotomy. Subsequently, the MAL was cut, and released to expose the celiac artery. Improved celiac artery blood flow was confirmed by decreased pulsatility index on intraoperative Doppler sonography. The operation was completed with the cervical esophagogastric anastomosis following cervical lymphadenectomy. Postoperative CECT on postoperative day 7 demonstrated increased celiac artery patency. The patient had an uncomplicated postoperative course thereafter. CONCLUSIONS: Prophylactic MAL release may be considered in patients with celiac artery stenosis due to compression by the MAL on preoperative CECT for esophagectomy.
