RESUMO
Vascular staplers are routinely used in laparoscopic liver resection, which has become a standard procedure in advanced medical facilities. Although previous reports have outlined the benefits of staple line reinforcement (SLR), its application in Glissonean pedicle transection during hepatic resection remains poorly studied. This study investigated surgical SLR as a tool to enhance staple line strength and improve perioperative hemostasis. Here, 10 patients who underwent laparoscopic liver resection using the Tri-StapleTM2.0 Reinforced Reload were included. Patient characteristics, surgical details, and outcomes were assessed. The results demonstrated successful outcomes with no complications related to bile leakage or injuries during staple insertion. Overall, our findings suggest that SLR can be safely utilized in Glissonean pedicle transection during laparoscopic liver resections. Further studies are required to comprehensively evaluate its benefits compared with conventional surgical staplers.

BACKGROUND: Anti-coagulant ileus, characterized by intramural hematoma due to excessive anti-coagulant therapy, presents a diagnostic challenge. Although previously considered uncommon, recently, reporting cases of anti-coagulant ileus have become more frequent. Herein, we report a rare surgical case of anti-coagulant ileus mimicking small-bowel tumors. CASE PRESENTATION: A 79-year-old man was admitted to our hospital for fatigue. He had been administered warfarin for 5 months for atrial fibrillation. On admission, the patient exhibited mild epigastric tenderness. Laboratory test results revealed anemia (hemoglobin, 8.4 g/dL); unmeasurably prolonged prothrombin time (PT) with international normalized ratio (INR) > 8; and elevated soluble interleukin 2 receptor (sIL-2R) levels (849 IU/mL; normal range, 122-496 IU/mL). Abdominal plain computed tomography (CT) showed a circumferentially thickened intestinal wall at one site in the jejunum and two in the ileum. After hospitalization, bowel obstruction did not improve with conservative treatment. Suspecting small-bowel tumors such as lymphoma, the patient subsequently underwent open surgery on day 3 after admission. No obvious tumor mass was observed intra-operatively. However, only thickened and hemorrhagic segments were identified at the suspected sites. We performed partial jejunal and ileal resections of 12 and 27 cm, respectively. Histopathology confirmed submucosal congestion, edema, and hemorrhage in each area without tumor components, leading to the final diagnosis of intramural hematoma. The postoperative course was uneventful, and he was discharged on postoperative day 9. No recurrence occurred during the 5-year follow-up period. CONCLUSIONS: We encountered a surgical case of anti-coagulant ileus, which was difficult to differentiate from malignant lymphoma based on CT findings and high sIL-2R levels. The possibility of anti-coagulant ileus should always be considered in patients on long-term anticoagulation medication and bowel obstruction with high PT-INR values.
RESUMO
OBJECTIVE: This study aimed to evaluate the effect of continuing preoperative aspirin monotherapy on surgical outcomes in patients receiving antiplatelet therapy (APT). SUMMARY BACKGROUND DATA: The effectiveness of continuing preoperative aspirin monotherapy in patients undergoing APT in preventing thromboembolic consequences is mostly unknown. METHODS: This prospective multicenter cohort study on the Safety and Feasibility of Gastroenterological Surgery in Patients Undergoing Antithrombotic Therapy (GSATT study) conducted at 14 clinical centers enrolled and screened patients between October 2019 and December 2021. The participants (n=1,170) were assigned to the continued APT group, discontinued APT group, or non-APT group, and the surgical outcomes of each group were compared. Propensity score matching was performed between the continued and discontinued APT groups to investigate the effect of continuing preoperative aspirin therapy on thromboembolic complications. RESULTS: The rate of thromboembolic complications in the continued APT group was substantially lower than that in the non-APT or discontinued APT groups (0.5% vs. 2.6% vs. 2.9%; P=0.027). Multivariate investigation of the entire cohort revealed that discontinuation of APT (P<0.001) and chronic anticoagulant use (P<0.001) were independent risk factors for postoperative thromboembolism. The post-matching evaluation demonstrated that the rates of thromboembolic complications were significantly different between the continued and discontinued APT groups (0.6% vs. 3.3%; P=0.012). CONCLUSIONS: APT discontinuation following elective gastroenterological surgery increases the risk of thromboembolic consequences, whereas continuing preoperative aspirin greatly reduces this risk. The continuation of preoperative aspirin therapy in APT-received patients is considered one of the best alternatives for preventing thromboembolism during elective gastroenterological surgery.
RESUMO
Background: Anastomotic leakage after esophagectomy affects the early postoperative state and prognosis. However, effective measures to prevent anastomotic leakage in esophagogastric anastomosis have not been established. Methods: This single-center, retrospective, observational study included 147 patients who underwent esophagectomy for esophageal cancer between 2010 and 2020. Glucagon was administered to extend the gastric tube in patients who underwent esophagectomy from January 2016. The patients were divided into two groups: a glucagon-treated group (2016-2020) and a control group (2010-2015). The incidence of anastomotic leakage was compared between the two groups for evaluation of the preventive effects of glucagon administration on anastomotic leakage. Results: The length of the gastric tube from the pyloric ring to the final branch of the right gastroepiploic artery was extended by 2.8 cm after glucagon injection. The incidence of anastomotic leakage was significantly lower in the glucagon-treated group (19% vs. 38%; p = 0.014). Multivariate analysis showed that glucagon injection was the only independent factor associated with a reduction in anastomotic leakage (odds ratio, 0.26; 95% confidence interval, 0.07-0.87). Esophagogastric anastomosis was performed proximal to the final branch of the right gastroepiploic artery in 37% patients in the glucagon-treated group, and these cases showed a lower incidence of anastomotic leakage than did those with anastomosis distal to the final branch of the right gastroepiploic artery (10% vs. 25%, p = 0.087). Conclusions: Extension of the gastric tube by intravenous glucagon administration during gastric mobilization in esophagectomy for esophageal cancer may be effective in preventing anastomotic leakage.
RESUMO
Local recurrence after colorectal liver metastasis (CRLM) resection severely affects survival; however, the required surgical margin width remains controversial. This study investigated the impact of KRAS status on surgical margin width and local recurrence rate (LRR) post-CRLM resection. Overall, 146 resected CRLMs with KRAS status (wild-type KRAS (wtKRAS): 98, KRAS mutant (mKRAS): 48) were included. The LRR for each group, R1 (margin positive) and R0 (margin negative), was analyzed by KRAS status. R0 was further stratified into Ra (margin ≥ 5 mm) and Rb (margin < 5 mm). Patients with local recurrence had significantly worse 5-year overall survival than those without local recurrence (p = 0.0036). The mKRAS LRR was significantly higher than wtKRAS LRR (p = 0.0145). R1 resection resulted in significantly higher LRRs than R0 resection for both wtKRAS and mKRAS (p = 0.0068 and p = 0.0204, respectively), and while no significant difference was observed in the Ra and Rb LRR with wtKRAS, the Rb LRR with mKRAS (33.3%) was significantly higher than Ra LRR (5.9%) (p = 0.0289). Thus, R0 resection is sufficient for CRLM with wtKRAS; however, CRLM with mKRAS requires resection with a margin of at least 5 mm to prevent local recurrence.
RESUMO
BACKGROUND: Gastrojejunostomy (GJ) is a surgical option for malignant gastric outlet obstruction (mGOO). Confronting an aging society, the demand to treat elderly cancer patients with unresectable malignancies is increasing; however, the benefit of GJ to the very elderly (≥ 80 years of age) has never been investigated. METHODS: This multicenter, retrospective review included 108 patients who had undergone GJ for mGOO from two medical centers in Japan, one of the most long-lived countries. Patients were divided into two groups, with 80 years of age as the cut-off. Various factors, including surgical complications and patient survival, were compared. RESULTS: GJ in the very elderly (aged ≥ 80 years) was associated with a higher incidence of surgical complications (p = 0.049), such as delayed gastric emptying (DGE; p < 0.001), aspiration pneumonia (p = 0.029), and consequent mortality (p = 0.016). Age ≥80 years was also identified as an independent predictor of DGE (odds ratio 6.444, p = 0.005) and survival after GJ (hazard ratio 7.767, p = 0.016). In particular, the median survival time after GJ in the population aged ≥80 years with gastric cancer was only < 2 months. About the surgical procedure, antiperistaltic anastomosis with partial stomach partitioning (PSP) yielded the lowest occurrence rate of DGE (3.4%) and aspiration pneumonia (1.7%). CONCLUSIONS: GJ does not seem to be the optimal choice for very elderly patients, particularly those with gastric cancer. If performed, antiperistaltic anastomosis with PSP should be employed to reduce the surgical complications.

Introduction: In rectal surgery, double-stapled anastomosis is one of the most common techniques. However, the crossing of the staple line is considered a weakness of this method and could lead to anastomotic leakage (AL), which is one of the major complications of rectal cancer surgery. Aim: To investigate the usefulness of laparoscopic intracorporeal reinforcement suturing for preventing AL in laparoscopic rectal surgery. Material and methods: A total of 153 patients with rectal cancer underwent laparoscopic rectal resection with anastomosis using the double-stapling technique between January 2015 and December 2018. Patient characteristics, surgical data, and outcomes were recorded and retrospectively analysed. Patients who received intracorporeal reinforcing sutures (n = 72) were compared with those who did not receive the reinforcing sutures (n = 81). Results: AL was observed in 11 (7.2%) cases overall and in only 1 case in the group with intracorporeal reinforcing sutures. There were no associations between clinicopathological factors and the use of reinforcing sutures. Multivariate analysis revealed that a distance from the anal verge of less than 6.5 cm, diabetes mellitus, and the non-use of reinforcing sutures were independent risk factors for AL. Conclusions: Laparoscopic intracorporeal reinforcing sutures reduced the incidence of AL. Therefore, laparoscopic reinforcing sutures for double-stapled anastomoses seem useful for the prevention of AL.
RESUMO
BACKGROUND: Preoperative evaluation of future remnant liver reserves is important for safe hepatectomy. If the remnant is small, preoperative portal vein embolization (PVE) is useful. Liver volume analysis has been the primary method of preoperative evaluation, although functional examination may be more accurate. We have used the functional evaluation liver using the indocyanine green plasma clearance rate (KICG) and 99mTc-galactosyl human serum albumin single-photon emission computed tomography (99mTc-GSA SPECT) for safe hepatectomy. AIM: To analyze the safety of our institution's system for evaluating the remnant liver reserve. METHODS: We retrospectively reviewed the records of 23 patients who underwent preoperative PVE. Two types of remnant liver KICG were defined as follows: Anatomical volume remnant KICG (a-rem-KICG), determined as the remnant liver anatomical volume rate × KICG; and functional volume remnant KICG (f-rem-KICG), determined as the remnant liver functional volume rate based on 99mTc-GSA SPECT × KICG. If either of the remnant liver KICGs were > 0.05, a hepatectomy was performed. Perioperative factors were analyzed. We defined the marginal group as patients with a-rem-KICG of < 0.05 and a f-rem-KICG of > 0.05 and compared the postoperative outcomes between the marginal and not marginal (both a-rem-KICG and f-rem-KICG > 0.05) groups. RESULTS: All 23 patients underwent planned hepatectomies. Right hepatectomy, right trisectionectomy and left trisectionectomy were in 16, 6 and 1 cases, respectively. The mean of blood loss and operative time were 576 mL and 474 min, respectively. The increased amount of f-rem-KICG was significantly larger than that of a-rem-KICG after PVE (0.034 vs 0.012, P = 0.0273). The not marginal and marginal groups had 17 (73.9%) and 6 (26.1%) patients, respectively. The complications of Clavian-Dindo classification grade II or higher and post-hepatectomy liver failure were observed in six (26.1%) and one (grade A, 4.3%) patient, respectively. The 90-d mortality was zero. The marginal group had no significant difference in postoperative outcomes (prothrombin time/international normalised ratio, total bilirubin, complication, post-hepatectomy liver failure, hospital stay, 90-d, and mortality) compared with the not-marginal group. CONCLUSION: Functional evaluation of the remnant liver enabled safe hepatectomy and may extend the indication for hepatectomy after PVE treatment.
RESUMO
Spontaneous esophageal perforation in Boerhaave's syndrome results in significant morbidity and mortality. The gold standard treatment for this disease is thoracotomy and laparotomy because it can be a life-saving procedure that can be performed in emergencies; however, minimally invasive surgery has recently been reported. This report describes three cases of Boerhaave's syndrome that were treated using laparoscopic transhiatal suture and omental patch. One patient recovered uneventfully and was discharged from the hospital after 12 days. The other 2 patients had postoperative complications, such as minor leakage and remnant abscess (Clavien-Dindo Grade II), but were discharged from the hospital after 17 days and 30 days, respectively. In the case of Boerhaave's syndrome with localized mediastinal collections, a good clinical course can be obtained by laparoscopic transhiatal esophageal repair to avoid surgical invasion due to thoracotomy.
RESUMO
LESSONS LEARNED: Three-month adjuvant capecitabine plus oxaliplatin in combination (CAPOX) appeared to reduce recurrence, with mild toxicity in postcurative resection of colorectal cancer liver metastases (CLM). Recurrence in patients who underwent the 3-month adjuvant CAPOX after resection of CLM was most commonly at extrahepatic sites. BACKGROUND: The role of neoadjuvant and adjuvant chemotherapy in the management of initially resectable colorectal cancer liver metastases (CLM) is still unclear. We evaluated the feasibility of 3-month adjuvant treatment with capecitabine plus oxaliplatin in combination (CAPOX) for postcurative resection of CLM. METHODS: Patients received one cycle of capecitabine followed by four cycles of CAPOX as adjuvant chemotherapy after curative resection of CLM. Oral capecitabine was given as 1,000 mg/m2 twice daily for 2 weeks in a 3-week cycle, and CAPOX consisted of oral capecitabine plus oxaliplatin 130 mg/m2 on day 1 in a 3-week cycle. Primary endpoint was the completion rate of adjuvant chemotherapy. Secondary endpoints included recurrence-free survival (RFS), overall survival (OS), dose intensity, and safety. RESULTS: Twenty-eight patients were enrolled. Median age was 69.5 years, 54% of patients had synchronous metastases, and 29% were bilobar. Mean number of lesions resected was two, and mean size of the largest lesion was 31 mm. Among patients, 20 (71.4%; 95% confidence interval, 53.6%-89.3%) completed the protocol treatment and met its primary endpoint. The most common grade 3 or higher toxicity was neutropenia (29%). Five-year recurrence-free survival and overall survival were 65.2% and 87.2%, respectively. CONCLUSION: Three-month adjuvant treatment with CAPOX is tolerable and might be a promising strategy for postcurative resection of CLM.

INTRODUCTION AND IMPORTANCE: Intersigmoid hernia (ISH) is a rare disease that is difficult to diagnose preoperatively and sometimes causes intestinal necrosis that requires emergency surgery. CASE PRESENTATION: The patient was an 87-year-old male with no history of abdominal surgery who visited our emergency outpatient service due to left lower quadrant pain and vomiting as chief complaints. Abdominal findings showed tenderness with the severest point in the left lower quadrant of the abdomen. Contrast-enhanced CT showed poor imaging of the dorsal sigmoid colon and an expanded proximal small intestine, with regional ascites around the small intestines. The patient was diagnosed with small bowel obstruction associated with ISH incarceration and underwent emergency surgery. Invagination of the small intestine into the intersigmoid fossa was found by laparoscopy. The incarcerated part was removed and the hernia orifice was sutured and closed. Mild congestion was seen in the incarcerated small intestine, but with no findings of ischemia. Thus, intestinal resection was determined to be unnecessary. The postoperative course was good and the patient was discharged on postoperative day 6. CLINICAL DISCUSSION: ISH is often diagnosed as simple ileus at the initial visit, which can result in delayed surgery. There are no case reports of complete remission of ISH with conservative therapy, and treatment with surgery is generally required. Our patient underwent early surgery because of CT findings that were characteristic of ISH and allowed diagnosis before surgery. CONCLUSION: Early diagnosis of ISH and performance of laparoscopic surgery can avoid the need for intestinal resection.
RESUMO
PURPOSE: We analyzed the impact of surgical margins and vessel preservation on the oncological outcomes of patients with colorectal liver metastases (CRLM). METHODS: In this retrospective study, resected CRLM (n = 242) from 116 patients were assigned to one of the following groups: Group A, apart from vessels (n = 201); Group B, hepatic vein contact (n = 27); or Group C, Glissonean pedicle contact (n = 25). We analyzed the local recurrence rates (LRR) in each group. RESULTS: The total LRR and that in Groups A, B, and C were 11.6%, 10.4%, 7.4%, and 20%, respectively. In group A, R1 resections were associated with a significantly higher LRR than R0 resections (27.6% vs 7.6%, respectively; P = 0.001); however, the margin widths were not related to the LRR. In group B, the LRR for hepatic vein preservation and resection did not differ. In group C, the Glissonean pedicle preservation group had a higher LRR than the Glissonean pedicle resection group (66.7% vs 5.3%, respectively; P = 0.001). The 5-year overall survival rate of the local recurrence group (25%) was significantly lower than that of the no recurrence group (84%, P < 0.001) and the intrahepatic recurrence group (60%, P = 0.026). CONCLUSION: R0 resections for CRLM, apart from those involving vessels, can achieve local control. While preserving hepatic vein contact with CRLM is acceptable, the Glissonean pedicle should be resected because of the higher LRR.

Background: Standardized protocols for laparoscopic surgery of splenic flexure cancer (SFC) have not been established yet. We described a standardized laparoscopic procedure for SFCs and examined its safety and feasibility. Methods: Laparoscopic colectomy for SFC was performed as follows. The sigmoid colon was mobilized to the descending mesocolon through the medial approach. After confirming the base of the inferior mesenteric artery, the left colic artery was dissected and resected at the base. Further dissection was carried out between the mesentery of the colon and the renal fascia until it exceeded the upper pole of the left kidney and the splenic flexure. The next dissection reached the white line at the lateral side and the sigmoid-descending colon junction. After making an incision at the greater omentum and gastrocolic ligament from the center of the transverse colon to the splenic flexure, the transverse mesocolon base was dissected from the inside splenic flexure for complete mobilization. This was performed by approaching from four directions toward the splenic flexure. Intestinal resection and anastomosis are performed. Results: This procedure was performed in 70 patients with splenic flexure colon cancer (mean age 70 years). The mean operative time was 190 minutes, and the mean blood loss was 2.0 mL. No notable perioperative or postoperative complications were noted. Conclusions: Safe mobilization of the splenic flexure can be achieved by approaching from four directions, and standardization of left colectomy can facilitate complete mesenteric excision.

BACKGROUND: Super-elderly patients with colorectal cancer are being encountered with increasing frequency in Japan. Laparoscopic surgery is considered a less invasive surgery in these patients; however, it is difficult to conduct controlled clinical trials in this super-elderly population. This study assessed the feasibility and safety of laparoscopic colorectal surgery in patients over 85 years old. MATERIALS AND METHODS: Open and laparoscopic surgeries for colorectal cancer in super-elderly patients (aged 85 y and older) were performed under general anesthesia in a single medical center. Records were retrospectively reviewed, and the clinicopathologic features of each patient and the surgical time and outcomes were recorded and analyzed. RESULTS: Records of colorectal surgery were reviewed for 108 super-elderly patients. Twenty-six open surgeries and 82 laparoscopic surgeries were performed. The mean operation times were 215 and 228 minutes in open and laparoscopic surgeries, respectively. Intraoperative bleeding in laparoscopic surgery was lesser than that in open surgery. There were 2 cases with major postoperative complications in open surgery, and mortality occurred in one case within 1 month after surgery. No major complications were observed in laparoscopic surgery. In survival analysis, disease-free survival did not differ between the 2 groups. The oldest patient was a man aged 102 years and 6 months who underwent laparoscopic anterior resection with lymph node dissection. CONCLUSION: Laparoscopic surgery in super-elderly patients with colon cancer is feasible and safe. The authors report the success of laparoscopic colectomy for rectosigmoid colon cancer in the oldest known patient and the positive outcomes of laparoscopic colectomy in super-elderly patients.

INTRODUCTION: Diaphragm disease is rare and caused by intestinal obstruction due to nonsteroidal anti-inflammatory drugs (NSAIDs). Given the availability of video capsule endoscopy (VCE) and balloon enteroscopy (BE) this disease will be diagnosed more often. PRESENTATION OF CASE: A 73-year-old man was presented to our hospital for persistent nausea and vomiting. Abdominal ultrasound and computed tomography revealed small-bowel thickening, stricture in the terminal ileum, and dilation of the proximal small intestine. Differential diagnosis included ileal lymphoma and multiple ileal adenocarcinomas, and a diagnostic laparoscopy was performed. Twenty-centimeter of ileum was resected by primary ileo-ileal anastomosis. On pathological examination, fibrosis of the submucosa was identified, and erosions and numerous inflammatory cells reaching the submucosa were also identified from the specimen. DISCUSSION: The preoperative diagnosis of diaphragm disease is sometimes challenging due to its uncharacteristic symptoms; moreover, radiological findings are usually indefinite and distinctive. Currently, the main treatment for diaphragm disease is surgery. CONCLUSION: We have documented a case of intestinal obstruction by NSAIDs. However, it is desirable to determine the course of treatment based on small bowel endoscopic dilatation cases in the future.
RESUMO
The prognosis of locally advanced gastric cancer is poor even if radical gastrectomy with D2 lymphadenectomy is followed by adjuvant chemotherapy. Hence, neoadjuvant chemotherapy is performed to try to improve the prognosis, as it can significantly downstage the tumor and safely improve the R0 resection rate of patients. Herein, we report a case of locally advanced gastric cancer with pancreatic invasion and gastric outlet obstruction that showed a pathological complete response after neoadjuvant chemotherapy with S-1 and oxaliplatin (SOX). A 74-year-old man presented to our hospital with abdominal pain and pyloric stenosis. CT images revealed a cStage IVb, cT4b tumor in the pancreas, cN1, cM0. Therefore, we performed laparoscopic gastrojejunostomy, and the patient's oral intake improved after surgery; we then administered neoadjuvant chemotherapy with SOX on postoperative day 18, without any surgical complications. After 3 courses of neoadjuvant chemotherapy, the patient underwent radical distal gastrectomy, thereby avoiding pancreatoduodenectomy. Histopathological examination of the resected sample revealed no residual cancer cells, indicating a pathological complete response. No recurrence has occurred for 1 year after surgery. Thus, neoadjuvant chemotherapy with SOX can help in tumor downstaging and may be a multipotent option for the treatment of locally advanced gastric cancer, such as cases with the invasion of other organs; this treatment can result in improved curability and avoid overinvasive surgery.
RESUMO
BACKGROUND: Colostomy via the intraperitoneal route is often performed during laparoscopic Hartmann's operation or abdominoperineal resection. Internal hernia of the small intestine often occurs after colostomy. This report shows a rare case of internal hernia of the stomach associated with sigmoid colostomy after laparoscopic abdominoperineal resection for rectal cancer. CASE PRESENTATION: The patient was a 79-year-old woman with a sigmoid colostomy. Computed tomography scan showed a markedly distended stomach in the space between the lifted sigmoid colon and the lateral abdominal wall. Laparoscopy revealed that the body of the stomach had passed through a hernia orifice located between the lifted sigmoid colon and the left lateral abdominal wall. The dislocated stomach was restored to its normal position, and the lateral defect was closed with the lateral peritoneum and the lifted sigmoid colon laparoscopically. CONCLUSIONS: Internal hernia associated with colostomy can lead to not only obstruction of the small intestine, but also obstruction of the stomach. We reported a successful case of the suture repair for the internal hernia of the stomach associated with colostomy.
RESUMO
BACKGROUND/PURPOSE: To investigate the long-term outcome and entire treatment course of patients with technically unresectable CRLM who underwent conversion hepatectomy and to examine factors associated with conversion to hepatectomy. METHODS: Recurrence and survival data with long-term follow-up were analyzed in the cohort of a multi-institutional phase II trial for technically unresectable colorectal liver metastases (the BECK study). RESULTS: A total of 22/12 patients with K-RAS wild-type/mutant tumors were treated with mFOLFOX6 + cetuximab/bevacizumab. The conversion R0/1 hepatectomy rate was significantly higher in left-sided primary tumors than in right-sided tumors (75.0% vs 30.0%, P = .022). The median follow-up was 72.6 months. The 5-year overall survival (OS) rate in the entire cohort was 48.1%. In patients who underwent R0/1 hepatectomy (n = 21), the 5-year RFS rate and OS rate were 19.1% and 66.3%, respectively. At the final follow-up, seven patients had no evidence of disease, five were alive with disease, and 20 had died from their original cancer. All 16 patients who achieved 5-year survival underwent conversion hepatectomy, and 11 of them underwent further resection for other recurrences (median: 2, range: 1-4). CONCLUSIONS: Conversion hepatectomy achieved a similar long-term survival to the results of previous studies in initially resectable patients, although many of them experienced several post-hepatectomy recurrences. Left-sided primary was found to be the predictor for conversion hepatectomy.

Patients with mixed neuroendocrine-nonneuroendocrine neoplasms (MiNENs) of the colon have poor prognosis. Herein, we report a patient with MiNEN of the colon with metastases to the liver and the thyroid gland, with long-term survival. A 45-year-old man presented with anterior neck swelling. Histopathological examination of the thyroid tumor revealed neuroendocrine carcinoma (NEC), suggesting that a primary NEC in another organ had metastasized to the thyroid gland. Computed tomography to identify a primary NEC revealed two tumors: one in the liver and one in the transverse colon. A biopsy revealed that the histopathology of the liver and colon tumors was NEC and adenocarcinoma, respectively. Thereafter, the patient underwent surgical resection of the colon tumor and was finally diagnosed as colon MiNEN with metastases to the thyroid and liver. The surgical resection of the metastatic liver tumor was performed after several courses of systemic chemotherapy, and the patient survives presently without any recurrence for approximately seven years after the diagnosis. Surgical resection of each metastatic lesion combined with systematic chemotherapy apparently improved the prognosis of MiNEN of the colon with distant metastases.
