Abstract
Familial adenomatous polyposis (FAP) is a heritable disease that increases the risk of colorectal cancer (CRC) development because of heterozygous mutations in APC. Little is known about the microenvironment of FAP. Here, single-cell RNA sequencing was performed on matched normal tissues, adenomas, and carcinomas from four patients with FAP. We analyzed the transcriptomes of 56,225 unsorted single cells, revealing the heterogeneity of each cell type, and compared gene expression among tissues. Then we compared the gene expression with that of sporadic CRC. Furthermore, we analyzed specimens of 26 FAP patients and 40 sporadic CRC patients by immunohistochemistry. Immunosuppressiveness of myeloid cells, fibroblasts, and regulatory T cells was upregulated even in the early stages of carcinogenesis. CD8+ T cells became exhausted only in carcinoma, although the cytotoxicity of CD8+ T cells was gradually increased according to the carcinogenic step. When compared with those in the sporadic CRC microenvironment, the composition and function of each cell type in the FAP-derived CRC microenvironment had differences. Our findings indicate that an immunosuppressive microenvironment is constructed from a precancerous stage in FAP.

Abstract
Subcutaneous emphysema (SE) is a complication of laparoscopic surgery, potentially resulting in severe respiratory failure. No reports to date have focused on SE during robot-assisted (RA) rectal surgery. We aimed to reveal the risk factors and clinical significance of SE after RA/laparoscopic rectal surgery. We retrospectively reviewed 221 consecutive patients who underwent RA/laparoscopic rectal surgery. The occurrence of SE was evaluated on postoperative radiographs. Laparoscopic surgery was performed in 120 patients and RA in 101. SE developed in 55 (24.9%) patients. Logistic regression analysis identified RA surgery (odds ratio [OR]: 4.89, 95% confidence interval [CI] 2.13-11.22, p < 0.001), higher age (OR: 1.06, 95% CI 1.03-1.11, p < 0.001), lower body mass index (BMI) (OR: 0.79, 95% CI 0.67-0.93, p = 0.004), thinner subcutaneous layer (OR: 0.88, 95% CI 0.79-0.98, p = 0.02), and lateral lymph node dissection (OR: 9.43, 95% CI 2.44-36.42, p < 0.001) as risk factors for SE. Maximum end-tidal CO2 was significantly higher in the SE than the non-SE cohort (p < 0.001). There was no difference in postoperative complication rate or length of hospital stay. Lower BMI (OR: 0.79, 95% CI 0.62-0.97, p = 0.02) and thinner subcutaneous layer (OR: 0.84, 95% CI 0.71-0.97, p = 0.01) were predictive factors in the RA cohort. SE occurs more frequently in RA compared with laparoscopic surgery. SE has a modest impact on short-term outcomes, but may occasionally cause severe problems. The indication of RA surgery should be considered carefully in high-risk elderly patients.

Abstract
BACKGROUND There are several options for the treatment of gastrointestinal stricture, including endoscopic stent placement and bypass surgery. However, a benign stricture is difficult to manage in a reconstructed gastric tube in the thoracic cavity owing to the technical difficulty of bypass surgery, and the possibility of stent migration. CASE PRESENTATION A 78-year-old woman was admitted to our hospital for treatment for her inability to eat. She had undergone video-assisted subtotal esophagectomy with retromediastinal gastric tube reconstruction 7 years earlier. At the current admission, there was a severely dilated gastric tube in the thoracic cavity with a soft stricture immediately anterior to the spine. Conservative therapy was ineffective; therefore, endoscopic stenting was performed. However, the stent migrated to the upper side of the stricture because the stricture was mild, and the stent was not fixed in the gastric tube. Next, endoscopic stent placement followed by laparoscopic stent fixation was performed. The stent was patent and worked well, and the patient's body weight increased. However, the stent collapsed 2 years later, with recurrence of symptoms. Stent-in-stent placement with an over-the-scope clip was performed, and the second stent was also patent and worked well. CONCLUSIONS Laparoscopic stent fixation with endoscopic stent placement could be an effective option for patients with a benign stricture in the reconstructed gastric tube.

Abstract
BACKGROUND/AIM Family history of colorectal cancer (CRC) is a known risk factor for CRC. However, its prognostic value in patients with CRC remains controversial. This study aimed to clarify the prognostic impact of a family history of CRC. PATIENTS AND METHODS We retrospectively reviewed the database from 1978 to 2018 and enrolled 3,655 consecutive patients with CRC. We investigated the clinicopathological factors of patients with CRC with and without a family history. After propensity score matching, we performed a survival analysis of patients with CRC with and without a family history. RESULTS Patients with CRC with a family history of CRC had a young onset (63.2 and 65.9; p<0.001), were more likely to be female (54.3% and 49.7%; p=0.042), had less symptomatic disease (76.9% and 80.8%; p=0.008), were more likely to have right-sided colon cancer (27.5% and 26.1%), and had less distant metastases (11.3% and 14.9%; p=0.023) and multiple CRCs (10.2% and 7.8%) compared with those without a family history of CRC. Prior to propensity score matching, CRC-specific survival analysis showed that a family history of CRC was a good prognostic factor (p=0.022). After propensity score matching, survival curves overlapped between the two groups. CONCLUSION Patients with CRC with a family history of CRC had specific clinicopathological features including younger onset, female sex, proximal colon location, fewer symptoms, smaller number of distant metastases, likelihood of multiple diseases, and earlier cancer stage. Family history of CRC in patients with CRC was not a prognostic factor.

Abstract
BACKGROUND Although radical antegrade modular pancreatosplenectomy for pancreatic ductal adenocarcinoma (PDAC) has become the gold standard procedure in open distal pancreatectomy, there has been no gold standardized procedure for PDAC in minimally invasive distal pancreatectomy (MIDP). In this study, we analyzed our novel cranial-to-caudal approach (CC approach) for patients undergoing MIDP and provide a video clip illustrating the details of the CC approach. METHODS Ninety-four patients who underwent MIDP with splenectomy between 2016 and 2021 were included in this study. The CC approach was performed in 23 (24.5%) of the 94 patients. The concept of the CC approach is easy identification of Gerota's fascia from the cranial side of the pancreas and secure tumor removal (R0 resection) wrapped by Gerota's fascia. The short- and long-term outcomes were compared between the CC and non-CC approaches. RESULTS The median operation time and blood loss were similar between the two groups. The ratios of grade ≥ B postoperative pancreatic fistula and Clavien-Dindo grade ≥ III complications were also comparable. All patients in the CC approach group achieved R0 resection, and the R0 ratio was similar in the two groups (p = 0.345). The 2-year survival rate in CC and non-CC approach groups was 87.5% and 83.6%, respectively (p = 0.903). CONCLUSIONS The details of the CC approach for MIDP were demonstrated based on an anatomical point of view. This approach has the potential to become a standardized approach for left-sided PDAC.

Abstract
Pagetoid spread (PS) of anorectal cancer is relatively rare and associated with poor prognosis. While a primary tumorous lesion is usually obvious in most PS cases, we experienced two cases of nonmass-forming type anorectal cancer with PS. It remains challenging to decide strategies. In both cases, histological findings of a perianal skin biopsy showed proliferation of atypical cells that were positive for cytokeratin (CK) 7, CK20, and caudal type homeobox 2 and negative for Gross cystic disease fluid protein 15, suggesting PS. Abdominoperineal resection (APR) with extensive anal skin resection was performed in both patients. The pathological diagnosis in each was nonmass-forming type anorectal cancer with PS. Neither has experienced recurrence in postoperative courses. Even nonmass-forming type anorectal cancer with PS could have high malignant potentials. APR with lymph nodes dissection and wide skin excision and regular surveillance might be necessary.

Abstract
Background Malnutrition impacts the clinical course of Crohn's disease; however, there is little evidence of its influence on perioperative adverse events. We assessed whether nutritional indicators are associated with postoperative complications in surgical treatment of Crohn's disease. Methods 137 patients with Crohn's disease who underwent surgical treatment between January 2011 and December 2020 were included. Skeletal muscle index was calculated by a single CT slice. We analyzed the risk factors for adverse events. Results 37 % of patients had postoperative complications. Adverse events occurred more frequently in patients with high serum C-reactive protein, low serum albumin, prognostic nutritional index <38.3, skeletal muscle index <38.9 cm2/m2, abdominoperineal resection, long surgical duration, and mass hemorrhage. Among patients with skeletal muscle index <38.9 cm2/m2, patients who experienced adverse events had higher visceral fat index compared with those who did not (0.85 vs. 0.45, P = 0.04). Multivariate analysis revealed that skeletal muscle index <38.9 cm2/m2 and low serum albumin were the independent risk factors for postoperative complications (Odds ratio, 2.85; 95 % confidence interval, 1.13-7.16; P = 0.03, 2.62; 1.09-6.26; P = 0.03, respectively). Separated by sex, low serum albumin (<3.5 and <2.8 g/dL, male and female, respectively) and skeletal muscle index (<38.9 and <36.6 cm2/m2, male and female, respectively) were statistically related to postoperative complications. Conclusions Skeletal muscle index is the most useful nutritional predictor of postoperative complications in Crohn's disease patients among other nutritional indices. We believe that these patients are at high risk of postoperative complications and need appropriate nutritional support in the perioperative period.

Abstract
BACKGROUND Palliative endoscopic stent placement may be considered in patients with malignant gastrointestinal obstruction. Stent migration is a potential complication, particularly for those placed at a surgical anastomosis or across a stricture caused by extra-alimentary tract factors. We report a patient with left renal pelvis cancer and gastrojejunostomy obstruction who underwent endoscopic stent placement and laparoscopic stent fixation. CASE PRESENTATION A 60-year-old male with peritoneal dissemination of a left renal pelvis cancer was admitted for treatment of upper gastrointestinal obstruction. A laparoscopic gastrojejunostomy had been previously performed for cancer invasion of the duodenum. Imaging showed gastroduodenal dilation and impaired passage of contrast medium through the efferent loop of the gastrojejunostomy. Gastrojejunostomy anastomosis site obstruction due to dissemination of left renal pelvis cancer was diagnosed. Conservative treatment failed and endoscopic stent placement with laparoscopic stent fixation was performed. After surgery, the patient was able to tolerate oral intake and he was discharged without complications. The patient gained weight and was able to resume chemotherapy, indicating the procedure was effective. CONCLUSIONS Endoscopic stent placement with laparoscopic stent fixation for malignant upper gastrointestinal obstruction appears effective in patients with a high risk of stent migration.

Abstract
BACKGROUND There are few reports describing the unusual origin of the inferior mesenteric artery (IMA). We report a rare case of advanced sigmoid colon cancer with the IMA arising from the superior mesenteric artery. CASE PRESENTATION A 59-year-old man with diarrhea and abdominal distention was diagnosed with advanced sigmoid colon cancer. Colonoscopy revealed a semi-circumferential cancer lesion in the sigmoid colon. Enhanced CT scan and CT angiography showed that the IMA directly originated from the superior mesenteric artery at the level of the second lumbar vertebra. PET-CT suggested metastases in the para-intestinal lymph nodes and the liver, but not in the central lymph nodes along the IMA. Preoperative diagnosis was sigmoid colon cancer cT4aN2aM1a cStage IVA(UICC, 8th edition). We performed laparoscopic complete resection as the radical treatment of the primary region prior to resection of the liver metastases. Intraoperative findings showed that the IMA was running parallel to the abdominal aorta; meanwhile, the colonic autonomic nerve was supplied from the lumbar splanchnic nerve at the caudal side of the duodenum. Central lymph nodes around the colonic autonomic nerve were dissected en bloc with the regional lymph nodes. Pathological radical resection including the regional lymph nodes metastasis was achieved. Two months later, complete resection of the liver metastasis was performed. After the adjuvant chemotherapy, no recurrence was observed 1.5 years after the liver resection was performed. CONCLUSIONS Preoperative confirmation of the anatomy helped us to safely complete radical surgery in a patient with unusual bifurcation of the IMA.

Abstract
BACKGROUND In recent years, the number of minimally invasive pancreatoduodenectomy (MIPD) has been increasing; however, the procedure has not been widely accepted due to its complexity and difficulty. We have developed a technique to mobilize the pancreas head using a left-sided approach with a focus on the complete dissection of the Treitz ligament. METHODS This technique focuses on the secure mobilization of the pancreas head using a left-sided approach. First, the transverse mesocolon is flipped upward and the anterior side of the mesojejunum is excised to expose the first jejunal artery (1st JA) from the distal side to its origin. During the procedure, the left sides of the SMA and Treitz ligament are exposed. The Treitz ligament is retracted to the left side and dissected anteriorly. Thereafter, the jejunum is flipped to the right side and the retroperitoneum around the origin of the jejunum and duodenum is dissected to identify the inferior vena cava (IVC). The rest of the Treitz ligament is dissected posteriorly and complete resection of the Treitz ligament releases the limitation of duodenal immobility. Thereafter, dissection proceeds along the anterior wall of the IVC, and mobilization of the pancreas head is completed from the left side. RESULTS A total of 75 consecutive patients underwent MIPD from April 2016 to July 2022. The median operation times of laparoscopic and robotic procedures were 528 min (356-757 min) and 739 min (492-998 min), respectively. The volume of blood loss during laparoscopic and robotic procedures was 415 g (60-4360 g) and 211 g (17-1950 g), respectively. There was no mortality in any of the cases. CONCLUSION Mobilization of the pancreas head and left-sided approach using a caudal view will be a safe and useful technique for MIPD.

Abstract
PURPOSE A diagnostic and treatment strategy for appendiceal tumors (ATs) has not been established. We aimed to evaluate our treatment strategy in ATs, including laparoscopic surgery (LS), and to identify preoperative malignancy predictors. METHODS A total of 51 patients between 2011 and 2021 were retrospectively reviewed. Data, including tumor markers and imaging findings, were compared between carcinoma and non-carcinoma patients. Validity of planned operation was evaluated based on pathological diagnosis. RESULTS Twenty-five patients were diagnosed with carcinoma, 13 with low-grade mucinous neoplasm, and 13 with other diseases. Symptoms were more commonly present in carcinoma patients than in non-carcinoma patients (68.0% vs. 23.1%, p = 0.001). Elevated CEA and CA19-9 were more frequently observed in carcinoma patients than in non-carcinoma patients (p < 0.01 and p = 0.04, respectively). Five carcinoma patients had malignancy on biopsy, compared with zero non-carcinoma patients. Significant differences were noted in the percentages of carcinoma and non-carcinoma patients with solid enhanced mass (41.7% vs. 0%, p < 0.001) and tumor wall irregularity (16.7% vs. 0%, p = 0.03) on imaging. Although the sensitivity was not high, the specificity and positive predictive value of these findings were 100%. Forty-two patients (82.4%) underwent LS as minimally invasive exploratory and/or radical operation, of whom 2 were converted to open surgery for invasion of adjacent organ. No patients had intraoperative complications or postoperative mortality. CONCLUSION Clinical symptoms, elevated tumor markers, and worrisome features of solid enhanced mass and tumor wall irregularity on imaging can be malignancy predictors. For management of ATs, LS is feasible and useful for diagnosis and treatment.

Abstract
For stage II and III esophageal squamous cell carcinoma (ESCC), neoadjuvant chemotherapy (NAC) followed by esophagectomy is recommended in the Japanese guidelines for the diagnosis and treatment of esophageal cancer. However, recurrence of ESCC is common regardless of the NAC regimen and surgical method, and NAC demonstrates limited efficacy against recurrence. Therefore, the present study was conducted to identify risk factors of recurrence of ESCC with surgery after NAC. The outcomes of 51 patients who underwent esophagectomy for ESCC after NAC from 2010 to 2017 at Kyushu University Hospital were retrospectively analyzed. A total of 52 patients with ESCC without NAC followed by esophagectomy from 2001 to 2017 were selected for comparison. Among patients who underwent NAC followed by surgery, only lymphatic invasion (LY; hazard ratio, 2.761; 95% CI, 1.86-6.43, P=0.018) was an independent factor significantly associated with 3-year recurrence-free survival in the multivariate analysis. In patients with pathologic lymph node metastasis (pN) and no LY after NAC, there was significantly less recurrence compared with patients with pN and LY (P=0.0085), whereas in patients without LY after NAC, the presence of pN was not significantly associated with recurrence (P=0.2401). There were significantly fewer LY (+) patients in the NAC (+) group (P=0.0158) compared with those in the NAC (−) group. The presence of LY was an independent risk factor for recurrence of ESCC after esophagectomy following NAC. Overall, adjuvant treatment after surgery may be required in cases with remnant LY after NAC.

Abstract
BACKGROUND/AIM Hereditary tumors are estimated to account for approximately 5-10% of all tumors. In Europe and the United States, multi-gene panel testing (MGPT) is the standard method used for identifying potential causative genes. However, MGPT it is still not widely used in Japan. The aim of this study was to assess the risk of hereditary tumors in Japanese cancer patients using germline MGPT and provide an overview of MGPT in the Japanese medical system. PATIENTS AND METHODS We used the myRiskTM, a 35-gene panel that determines the risk for eight hereditary cancers: breast, ovarian, gastric, colorectal, prostate, pancreatic, malignant melanoma, and endometrial cancers. RESULTS From June 2019 to March 2020, 21 patients who were suspected to have hereditary tumors were included, based on their family or medical history. Pathogenic variants were found in 7 patients [BRCA1 (5), MSH6 (1), TP 53 (1)]. CONCLUSION In this study, despite the small number of participants, we were able to show the significance of MGPT in Japan. Therefore, MGPT should be used for evaluating hereditary tumors in clinical practice.

Abstract
Postoperative adjuvant chemotherapy for patients with stage III colon cancer (CC) is regarded as the standard treatment worldwide for outcome improvement and relapse prevention. Similarly, high-risk stage II CC requires adjuvant chemotherapy because of its high recurrence rate. Previous randomized controlled trials showed that oxaliplatin (OX), in addition to fluorinated pyrimidine-based therapy for patients with stage II/III CC, significantly improves cancer survival but it remains controversial as to which patient groups should receive OX-containing regimens. Among 1,150 consecutive patients who underwent curative resection for stage II/III CC between 2009 and 2016 at two tertiary hospitals, 349 patients treated with only peroral (PO) fluorinated pyrimidine-based chemotherapy and 149 patients who received fluorinated pyrimidine-based chemotherapy with OX as adjuvant chemotherapy were retrospectively reviewed. The primary outcome was recurrence-free survival (RFS). Clinicopathological factors were more advanced in patients treated with OX than in patients treated only with PO fluorinated pyrimidine agents. Multivariate analysis for 5-year RFS showed that T4 [hazard ratio (HR), 2.947; P=0.0001], N2 (HR, 2.704; P=0.0075), vessel or lymphatic invasion (HR, 1.675; P=0.0437) and high cancer antigen (CA)19-9 (HR 3.367, P=0.0002) levels were independent risk factors of cancer relapse. Propensity score matching analysis was performed to match clinicopathological differences between the PO and OX groups. After matching, subgroup analysis of the patients showed that greater effects of OX on cancer survival were observed in patients in the OX group with high CA19-9 levels and tended to be associated with T4 and N2 compared with the PO group. Thus, OX-containing regimens should be recommended for patients with CC with these factors in an adjuvant setting.

Abstract
Background The aim of this study was to compare the short-term outcomes of the duodenum-first multidirectional approach (DMA) in laparoscopic right colectomy with those of the conventional medial approach to assess its safety and feasibility. Methods This retrospective study enrolled 120 patients who had laparoscopic surgery for right-sided colon cancer in our institution between April 2013 and December 2019. Fifty-four patients underwent colectomy using the multidirectional approach; among these, 20 underwent the DMA and 34 underwent the caudal-first multidirectional approach (CMA). Sixty-six patients underwent the conventional medial approach. Complications within 30 days of surgery were compared between the groups. Results There were 54 patients in the multidirectional group [29 females, median age 72 years (range 36–91 years)] and 66 in the medial group [42 females, median age 72 years (range 41–91 years)]. Total operative time was significantly shorter in multidirectional approach patients than conventional medial approach patients (208 min vs. 271 min; p = 0.01) and significantly shorter in patients who underwent the DMA compared to the CMA (201 min vs. 269 min; p < 0.001). Operative time for the mobilization procedure was also significantly shorter in patients who underwent the DMA (131 min vs. 181 min; p < 0.001). Blood loss and incidence of postoperative complications did not differ. In 77 patients with advanced T3/T4 tumors, the DMA, CMA, and conventional medial approach were performed in 13, 21, and 43 patients, respectively. Total operative time and operative time of the mobilization procedure were significantly shorter in patients undergoing DMA. Blood loss and incidence of postoperative complications did not differ. R0 resection was achieved in all patients with advanced tumors. Conclusions The DMA in laparoscopic right colectomy is safe and feasible and can achieve R0 resection with a shorter operative time than the conventional medial approach, even in patients with advanced tumors.

Abstract
In the frequency-domain multiplexing (FDM) scheme, transition-edge sensors (TESs) are individually coupled to superconducting LC filters and AC biased at MHz frequencies through a common readout line. To make efficient use of the available readout bandwidth and to minimize the effect of non-linearities, the LC resonators are usually designed to be on a regular grid. The lithographic processes, however, pose a limit on the accuracy of the effective filter resonance frequencies. Off-resonance bias carriers could be used to suppress the impact of intermodulation distortions, which, nonetheless, would significantly affect the effective bias circuit and the detector spectral performance. In this paper, we present a frequency shift algorithm (FSA) to allow off-resonance readout of TESs, while preserving the on-resonance bias circuit and spectral performance, demonstrating its application to the FDM readout of an x-ray TES microcalorimeter array. We discuss the benefits in terms of mitigation of the impact of intermodulation distortions at the cost of increased bias voltage and the scalability of the algorithm to multi-pixel FDM readout. We show that with FSA, in the multi-pixel and frequencies shifted on-grid, the line noises due to intermodulation distortion are placed away from the sensitive region in the TES response and the x-ray performance is consistent with the single-pixel, on-resonance level.

Abstract
Uniform large transition-edge sensor (TES) arrays are fundamental for the next generation of x-ray space observatories. These arrays are required to achieve an energy resolution ΔE < 3 eV full width at half maximum (FWHM) in the soft x-ray energy range. We are currently developing x-ray microcalorimeter arrays for use in the future laboratory and space-based x-ray astrophysics experiments and ground-based spectrometers. In this contribution, we report on the development and the characterization of a uniform 32 × 32 pixel array with 140 × 30 μm2 Ti/Au TESs with the Au x-ray absorber. We report on extensive measurements on 60 pixels in order to show the uniformity of our large TES array. The averaged critical temperature is Tc = 89.5 ± 0.5 mK, and the variation across the array (∼1 cm) is less than 1.5 mK. We found a large region of detector's bias points between 20% and 40% of the normal-state resistance where the energy resolution is constantly lower than 3 eV. In particular, results show a summed x-ray spectral resolution ΔEFWHM = 2.50 ± 0.04 eV at a photon energy of 5.9 keV, measured in a single-pixel mode using a frequency domain multiplexing readout system developed at SRON/VTT at bias frequencies ranging from 1 MHz to 5 MHz. Moreover, we compare the logarithmic resistance sensitivity with respect to temperature and current (α and β, respectively) and their correlation with the detector's noise parameter M, showing a homogeneous behavior for all the measured pixels in the array.

Abstract
Recently, several scholars have demonstrated the efficacy of carbon ion radiotherapy (CIRT). To treat abdominal or pelvic tumors by CIRT, it is necessary to separate the tumor from the adjacent organs. Surgical placement of a GORE-TEX sheet as a spacer has been reported as a separation method. Usually, surgical spacer placement is done by open surgery. Here, we report a case of surgical spacer placement undertaken by a "pure" laparoscopic procedure. A 47-year-old man with recurrent sacral chordoma was referred for surgical spacer placement before CIRT. Laparoscopic dissection of the rectum and placement of a GORE-TEX sheet as a spacer were successfully performed. Surgical spacer placement by a pure laparoscopic procedure was safe and effective, and it seems to play an important part before CIRT.

Abstract
PURPOSE To investigate optimal risk factors, including atrophy of the abdominal rectus muscle (ARM) for postoperative parastomal hernia (PH) in patients who underwent end colostomy at left lower quadrant. METHODS This single-institution retrospective study included 91 patients who underwent end colostomy between April 2004 and December 2015. The surgical and long-term outcomes among patients with or without PH were collected and compared. RESULTS Altogether, 22 (24.2%) patients had a PH including 15 (68.2%) patients with a simultaneous incisional hernia. Univariate analysis showed that older patients (71 ± 11.9 vs. 64 ± 12.2 years, p = 0.03) and those with higher body mass index (BMI) (23.8 ± 3.8 vs. 20.9 ± 3.3 kg/m2, p < 0.001) had a statistically significant relation with having PHs. Relative atrophy of left abdominal rectus muscle was more frequently found in patients with PH (ratio of left side/right side; caudal level and medial side: 0.66 vs. 0.92, p < 0.01, caudal level and lateral side: 0.95 vs. 1.03, p = 0.04). Multivariate analysis revealed that BMI > 25 kg/m2 [odds ratio (OR) 9.05, 95% confidence interval (CI) 2.06-39.76, p = 0.003] and atrophy of the left lower medial portion of the abdominal rectus muscle (OR 12.85, 95% CI 2.49-66.39, p = 0.002) were independent risk factors for PHs. Neither the laparoscopic approach nor the extraperitoneal route of the colostomy was proven to correlate with a lower rate of PHs. CONCLUSIONS High BMI and atrophic change of ARM were significantly associated with PH development. Surgical techniques for prevention of atrophic change of ARM are expected to reduce the incidence of PHs.

Abstract
Laparoscopic D3 lymph node dissection for transverse colon cancer is technically demanding because of complicated anatomy. Here, we reviewed the vascular structure of the transverse mesocolon, explored the extent of the base of the transverse mesocolon, and evaluated the feasibility and oncological safety of D3 lymph node dissection. We retrospectively reviewed the clinical records of 42 patients with advanced transverse colon cancer who underwent curative surgery and D3 dissection at Kyushu University Hospital between January 2008 and December 2015. We examined the venous and arterial anatomy of the transverse mesocolon of each resection and compared surgical outcomes between patients who underwent laparoscopic D3 (Lap D3) and open D3 (Open D3) dissection. Patients included two with Stage I, 18 with Stage II, 20 with Stage III, and two with Stage IVA. Thirty-six (85.7%) and six (14.3%) patients underwent Lap D3 or Open D3, respectively. The tumor sizes of the Open D3 and Lap D3 groups were 7.8 and 3.7 cm, respectively (P < 0.001). The Lap D3 group had significantly less blood loss (26 mL vs 272 mL, P = 0.002). The other outcomes of the two groups were not significantly different, including 3-year overall survival (87.7% vs 83.3%, P = 0.385). We observed four patterns of the middle colic artery (MCA) arising from the superior mesenteric artery (SMA), and the frequency of occurrence of a single MCA was 64.3%. The right-middle colic vein (MCV) was present in 92.9% of resections and served as a tributary of the gastrocolic trunk, and 90.5% of the left MCVs drained into the superior mesenteric vein (SMV). The root of the transverse mesocolon was broadly attached to the head of the pancreas and to the surfaces of the SMV and SMA. Laparoscopic D3 lymph node dissection may be tolerated by patients with advanced transverse colon cancer.

Abstract
Retrorectal tumors (RT) are uncommon and usually managed by open surgical excision. Laparoscopic excision for RT has been reported in only a small number of papers. We aimed to assess the laparoscopic approach for RT and to discuss the factors that made this procedure difficult. We performed laparoscopic excision using a five-trocar technique for neurogenic RT in three patients. Tumors were successfully excised laparoscopically in two patients. However, the third patient required open conversion because the tumor was strongly adhered to the sacrum and could not be mobilized by dissection, resulting in poor visualization of the dissected site. Laparoscopic excision for RT provides excellent intraoperative visualization and good cosmesis in selected patients, but firm adherence to the sacrum may cause difficulty with this procedure.

Abstract
BACKGROUND The laparoscopic approach for complex Crohn's disease (CD), which involves abscess formation, fistula formation, and recurrent CD, is controversial. The aim of this study was to investigate the feasibility and safety of the laparoscopic approach for complex CD. METHODS Fifty-six patients who had undergone surgery for CD of the small bowel from January 2007 to August 2014 were divided into two groups: the laparoscopic approach for complex CD group (LC group, n = 31) and the laparoscopic approach for simple CD group (LS group, n = 25). The preoperative data and surgical outcomes of the LC group were compared with those of the LS groups. RESULTS There were no significant differences in preoperative data and operating time between the two groups. Blood loss was not significantly different between the LC and LS groups. The incision length was longer in the LC group than the LS group (P = 0.004). The incidence of severe postoperative complications in the LC group was higher than in the LS group (P = 0.026). The length of postoperative stay was similar in the LC and LS groups. CONCLUSIONS The laparoscopic approach for complex CD is feasible and provides good cosmesis that is comparable to that offered by simple CD.

Abstract
Sclerosing mesenteritis (SM) is a rare inflammatory and fibrosing disease primarily involving the small-bowel mesentery. Recently, SM was reported to be closely related to IgG4-related disease (IgG4-RD). This report describes a patient with SM associated with IgG4-RD. A 77-year-old woman with a history of surgery for ectopic pregnancy and wound dehiscence presented with intestinal obstruction. Abdominal enhanced computed tomography (CT) revealed an enhanced, radially shaped, oval mass, 3 cm in diameter, with an unclear rim in the mesentery of the distal ileum, which may have involved the distal ileum. To remove the cause of bowel obstruction, the SM was resected completely and the ileum was resected partially. Histologic examination showed that the mass was composed of spindle cells arranged in a fascicular or storiform pattern; moreover, fibrous stroma was observed, with dense lymphoplasmacytic infiltration and lymphoid follicles. Immunohistochemically, numerous IgG4-positive plasma cells were observed, at a density of 253 per high-powered field, and the IgG4/IgG ratio was about 50 %. Elastica van Gieson (EVG) staining also showed obstructive phlebitis. These findings indicated IgG4-related SM. Although the accurate diagnosis of SM remains difficult without histological analysis, IgG4-RD should be included in the differential diagnosis of unknown mesenteric tumors. Identification of IgG4-RD may prevent unnecessary surgery because corticosteroids may be effective in these patients.

Abstract
AIM This study was planned to evaluate the efficacy and safety of preoperative capecitabine and oxaliplatin (XELOX) without radiation in patients with locally advanced lower rectal cancer. PATIENTS AND METHODS Patients with clinical stage II/III lower rectal cancer underwent three cycles of XELOX followed by radical surgery. The primary end-point was the R0 resection rate. RESULTS Thirty-one patients were recruited between February 2012 and August 2014. The completion rate of neoadjuvant chemotherapy was 96.5% among the 29 patients who received it; the remaining two refused chemotherapy and underwent immediate surgery. Grade 3-4 adverse events occurred in nine patients (31%). All 29 patients who received chemotherapy underwent radical resection. The R0 resection rate was 96.5% among these 29 patients. Pathological complete responses were achieved in three patients (10.3%) and downstaging occurred in 13 (44.8%). CONCLUSION This pilot study found that neoadjuvant XELOX for locally advanced lower rectal cancer is feasible and safe. This neoadjuvant treatment improved resection margin status.

Abstract
INTRODUCTION We introduced a reduced-port procedure for laparoscopic restorative proctocolectomy without diverting ileostomy for patients with familial adenomatous polyposis and ulcerative colitis. MATERIALS AND SURGICAL TECHNIQUE A multichannel port was inserted through a 2.5-cm umbilical incision. A 12-mm port in the right lower abdomen and a 3- or 5-mm port were also employed. A proctocolectomy was performed intracorporeally, and the entire colon and rectum were delivered through the umbilical incision. An ileal J-pouch was made extracorporeally following division of the mesenteric vessels. Ileal j-pouch-anal anastomosis was performed intracorporeally or transanally after rectal mucosectomy. A drain was inserted through the 12-mm port incision, and a transanal decompression tube was placed in the pouch. Two women and one man underwent this surgery, and their postoperative recovery was uneventful. DISCUSSION Laparoscopic restorative proctocolectomy without a diverting stoma by a reduced-port technique is feasible and provides excellent cosmetic outcomes in selected patients.

Abstract
BACKGROUND Laparoscopic lateral pelvic lymph node dissection (LPLD) is a minimally invasive alternative to open surgical therapy for advanced low rectal cancer patients. This study assessed potential risk factors for lateral pelvic lymph node metastasis (LPLM) and evaluated the feasibility and oncological safety of laparoscopic LPLD compared with the conventional open approach. METHODS We retrospectively reviewed the clinical records of 90 patients with advanced low rectal cancer who underwent LPLD following total mesorectal excision at Kyushu University Hospital between January 2001 and July 2014. We compared the clinicopathological features between the patients with and without LPLM and the surgical outcomes between patients who underwent laparoscopic LPLD (LL) and open LPLD (OL). RESULTS Fourteen (15.6 %) patients had LPLM. Univariate analysis revealed that undifferentiated cancer, positive lymphatic invasion, >50 % circumferential cancer extent, mesorectal lymph node metastases (MLM), and distant metastasis were associated with LPLM. In the multivariate analysis, MLM was the only independent risk factor for LPLM. Forty-six (51.1 %) patients underwent LL, and 44 (48.9 %) patients underwent OL. The mean surgical duration was longer in the LL group than in the OL group (641.0 vs. 312.0 min, P < 0.001). The LL group also had less hemorrhage (252.0 vs. 815.0 mL, P < 0.001) and a shorter hospital stay (22.9 vs. 29.1 days, P = 0.04) than the OL group. The mean number of harvested lateral pelvic lymph nodes was larger in the LL group than in the OL group (19.5 vs. 15.8, P < 0.05). The morbidity rate and overall survival (3-year OS: 94.7 vs. 82.9 %, P = 0.25) did not differ between the two groups. CONCLUSIONS Patients with advanced low rectal cancer presenting MLM are good candidates for LPLD. Laparoscopic LPLD enables retrieval of more lymph nodes and may be acceptable for the treatment of advanced low rectal cancer.

Abstract
A shortage of surgeons has been a serious problem in recent years. There is an urgent need to utilize female surgeons who tend to resign because of bearing and raising of children. To examine possible measures to deal with the issue, we performed questionnaire survey about work-life balance and career planning on 20 female surgeons in the Department of Surgery and Oncology, Kyushu University. The response rate was 80.0%. In the 16 respondents, seven were unmarried and nine were married. A large fraction of the respondents recognized the importance of work-life-balance. Female surgeons have many difficulties to continue working with good work-life balance; therefore, understanding and cooperation of both their spouses and coworkers is considered to be necessary. Married female surgeons considered that improvement of the working environment and sufficient family support were more important for good work-life balance compared to those who were unmarried. Female surgeons should recognize the importance of improvement of their environment, including the workplace and the family to continue working with good work-life balance in youth and should have the prospects about their career plan of their own.

Abstract
Reliable predictors of tumor recurrence for patients with stage II colorectal cancer (CRC) are needed to select patients who should receive adjuvant chemotherapy. Although galanin (GAL) is expressed in several malignant tumors and is associated with cell proliferation and tumor growth, the prognostic value of GAL expression in CRC is poorly understood. We compared GAL expression between 56 patients with stage II and III CRC who developed tumor recurrences and 56 patients who did not. The clinical and prognostic significance of GAL expression was examined using our data and independent public datasets. We also analyzed the influence of GAL expression on the proliferation and invasive activity of CRC cells. Higher expression of GAL was associated with tumor recurrence among the CRC patients (P<0.001). Stage II CRC patients who presented with high expression levels of GAL had significantly poorer prognosis than those with low expression levels of GAL [5-year overall survival: hazard ratio (HR), 7.31; 95% confidence interval (CI), 2.38–24.04; P<0.001; 5-year recurrence-free survival: HR, 3.99; 95% CI, 1.61–9.44; P=0.004], but there was no association between GAL expression and survival in stage III CRC patients. These findings were supported by analysis of two public datasets. Functionally, siRNA-mediated silencing of GAL resulted in a significant decrease in the proliferative and invasive activities of CRC cells. In conclusion, high expression of GAL is associated with poor prognosis of stage II CRC patients and GAL expression may be related to the aggressive behavior of CRC.

Abstract
A subset of colorectal cancers (CRCs) harbor the CpG island methylator phenotype (CIMP), with concurrent multiple promoter hypermethylation of tumor-related genes. A serrated pathway in which CIMP is developed from serrated polyps is proposed. The present study characterized CIMP and morphologically examined precursor lesions of CIMP. In total, 104 CRCs treated between January 1996 and December 2004 were examined. Aberrant promoter methylation of 15 cancer-related genes was analyzed. CIMP status was classified according to the number of methylated genes and was correlated with the clinicopathological features, including the concomitant polyps in and around the tumors. The frequency of aberrant methylation in each CRC showed a bimodal pattern, and the CRCs were classified as CIMP-high (CIMP-H), CIMP-low (CIMP-L) and CIMP-negative (CIMP-N). CIMP-H was associated with aberrant methylation of MLH1 (P=0.005) and with an improved recurrence-free survival (RFS) rate following curative resection compared with CIMP-L/N (five-year RFS rate, 93.8 vs. 67.1%; P=0.044), while CIMP-N tumors were associated with frequent distant metastases at diagnosis (P=0.023). No concomitant serrated lesions were present in the tumors, whereas conventional adenoma was contiguous with 11 (10.6%) of 104 CRCs, including four CIMP-H CRCs. CIMP-H was classified in CRCs by a novel CIMP marker panel and the presence of concomitant tumors revealed that certain CIMP-H CRCs may have arisen from conventional adenomas.

Abstract
We report the case of a 54-year-old woman who developed epigastralgia and vomit. Because of the abnormal gas in the epigastrium on abdominal X-ray, ileus due to foramen of Winslow hernia or left paraduodenal hernia was suspected. However, abdominal CT and barium study revealed the gas in the epigastrium to be the air in the transverse colon interposed between the stomach and pancreatic body. This anomalous interposition of the transverse colon is called retrogastric colon. The ileus was due to non-specific inflammatory duodenal stenosis. It is important to prevent misdiagnosis of retrogastric colon as lesser sac pathologic condition such as abscess, bowel perforation and internal hernia.

Abstract
We obtained diffusion-weighted echo planar images of the human cervical cord in vivo and correlated them with histopathologic findings. Images were obtained in 17 healthy volunteers using a 1.5 T clinical MR unit. When motion-probing gradients were added perpendicular to the long axis of the cord, the white matter was hyperintense because of anisotropic diffusion. However, the gracile fasciculus was hypointense probably due to the small diameter of neural fibers and the large extracellular space.

Abstract
Transradial angiography has recently emerged as an alternative to the transfemoral or transbrachial approach, especially for coronary procedures. However, there have been few studies on cerebral angiography using the transradial approach. The purpose of this study was to assess the outcomes, complications, and limitations of selective cerebral angiography via the transradial approach. Selective cerebral angiography by the right transradial approach using 100-cm-long 4-F catheters was performed in 83 patients. Using five types of catheters, the success rates of selective catheterization to the right vertebral artery, right common carotid artery, left common carotid artery, and left vertebral artery were 40/44 (91%), 68/68 (100%), 62/62 (100%), and 14/25 (56%), respectively. Puncture failed in one patient, and a guidewire could not be introduced beyond the radial artery loop in one patient. Radial artery spasm occurred in one patient, but was relieved immediately after nitroglycerin injection through the sheath with side holes. Subcutaneous bleeding occurred in six patients, but no obvious hematomas were noted. Occlusion or stenosis of the radial artery occurred in five patients, but no ischemic symptoms were observed in any of the cases. This study suggested that selective cerebral angiography can be performed safely using the transradial approach.

Abstract
We evaluated the image quality of non-contrast enhanced 2D-TOF MRA of the calf and the efficacy of cardiac gating and leg warming. In 10 healthy volunteers, MRA was carried out under the following four conditions: (a) usual MRA, (b) MRA with cardiac gating, (c) MRA after leg warming and (d) MRA with cardiac gating after leg warming. Although MRA with cardiac gating was not suitable, MRA after leg warming was well suited to the imaging of calf arteries. The image quality of MRA with cardiac gating after leg warming was the same as that of MRA after leg warming.

Abstract
To delineate the white and gray matter of the normal human cervical spinal cord, diffusion-weighted echo planar imaging (DW-EPI) was performed in 11 healthy volunteers. Three axial (X-, Y- and Z-axis) anisotrophic diffusion-weighted images were obtained on a 1.5T superconducting clinical unit using a single-shot DW-EPI sequence. On X- and Y-axis DWIs the white and gray matter could be well differentiated: the former showed high intensity and the latter low intensity. Anterior columns were clearly visible, whereas posterior columns were not. On Z-axis DWI the white and gray matter could not be differentiated at all, because both showed low intensity. In conclusion, DW-EPI can clearly delineate the white and gray matter of the cervical spinal cord, and this technique will be useful to evaluate white matter disorders such as ischemic or demyelinating disease.

Abstract
We evaluated the imaging quality of 2D-TOF MR venography of the lower part of the leg and the efficacy of a tourniquet around the knee and leg-warming. In 8 healthy volunteers, MR venography was carried out under the following four conditions: (a) usual MR venography, (b) MR venography with tourniquet around the knee, (c) MR venography after leg-warming and (d) MR venography with tourniquet after leg-warming. Our results suggested that MR venography with tourniquet after leg-warming is best suited for imaging the veins of the leg. We also compared the diagnostic image quality of MR venography and conventional contrast venography in 7 patients with varices. The results showed no significant differences between the two methods. We conclude that MR venography with tourniquet after leg-warming is a technique that provides reliable information about the veins of the leg.

Abstract
Twenty-nine patients with intracranial meningiomas were treated with a high-energy linear accelerator (4-10 MV. X rays and electron beams) between 1980 and 1992 at the Hiroshima Prefectural Hiroshima Hospital. We investigated the relationships between tumor size and tumor response, histological type and tumor response, and grade of operation using Simpson's classification and recurrence rate. Meningiomas were greatly reduced between 1 month and 46 months after radiotherapy, the average being 14 months. In the group with a tumor size of less than 5 cm2, 3 patients obtained CR, 5 patients NC and 1 patient PD. Tumor response was 89% in the group with a combination of CR with NC. In the group with a tumor size of 5 to 20 cm2, 2 patients obtained PR, 1 patient NC and 1 patient PD. Tumor response was 75% in the group with a combination of PR with NC. In the group with a tumor size of more than 20 cm2, 3 patients showed NC, 3 patients PD. Tumor response was 50% in the group with NC. In the group with a tumor size of less than 20 cm2, tumor response was 85%. In the group with a tumor size of more than 20 cm2, it was 50%. Though there were no statistically significant differences between the two groups, a tumor size of less than 20 cm2 had a tendency to be more responsive than one of more than 20 cm2. The response of meningioma of the transitional type was worse than that of the meningothelial type and fibroblastic type. Fourteen patients after Simpson grade II or III operation were free of recurrence. The results of this study support the role of radiotherapy for meningioma which is less than 20 cm2, and also for treatment after Simpson grade II or III operation.

Abstract
We studied the value of short-TI inversion-recovery (STIR) imaging for the localization of pancreatic insulinoma. Four patients (three women and one man aged 35-65 years) with surgically proven insulinoma were included in this study. All patients were examined by MR imaging with spin echo (SE) and STIR sequences. The STIR images were compared with the histopathologic findings in each case. In two patients, the tumors were markedly hyperintense on STIR images, and a 5-mm insulinoma was depicted only by this imaging method in one of the two. In the other two patients, 10-mm insulinomas were only slightly hyperintense on STIR images. The latter tumors had a higher content of collagen fibers than the former, indicating that the amount of collagen influences the signal intensity of insulinoma. Despite some limitations, STIR imaging is a useful noninvasive method for the localization of pancreatic insulinoma.

Abstract
We report a patient with focal renal vein thrombosis that presented as a hyperdense mass mimicking a hyperdense cyst or a pelvic or parenchymal tumor. The lesion was described as a well-defined round hyperdense mass in the right renal sinus on noncontrast CT and was surgically proven to be acute thrombosis of the renal vein. Renal vein thrombosis should be considered in the differential diagnosis of a hyperdense mass in the renal sinus even if the patient has no underlying renal abnormality.

Abstract
We have established a cell culture system without stromal cells that allows the CD34+ hematopoietic progenitor cells (HPC) to differentiate into natural killer (NK) cells. CD34+Lin (CD3, CD16, CD56)- cells were purified using fluorescence-activated cell sorting from normal adult bone marrow (BM) and cultured for 28 days in medium supplemented with interleukin-2 (IL-2) and stem cell factor (SCF). NK (CD3-CD16-CD56+) cells were generated in a dose-dependent manner in response to SCF. NK cells originated from CD34+CD33+Lin- cells, but they were barely detectable in cultures of CD34+CD33-Lin- cells. However, on addition of IL-3, an induced differentiation of NK cells from CD34+CD33-Lin- cells was observed, although at a lower frequency. Supplementing of the cell cultures with SCF alone or both SCF and IL-3 for the first 7 days followed by IL-2 for the next 21 days is essential for production of NK cells from CD34+CD33+Lin- cells and from CD34+CD33-Lin- cells, respectively. These data provide direct evidence that NK cells arise from CD34+HPC and show the minimum lymphokine requirement for their differentiation.

Abstract
We report 2 cases of adrenal pseudocysts that resulted from hemorrhage into a normal adrenal gland and that showed atypical imaging features on computerized tomography and ultrasonography. The presence of a solid component within the mass and/or central calcification, which is unlike the typical features of adrenal pseudocyst, suggested a diagnosis of adrenal tumor. The solid component diminished on computerized tomography in 26 days in case 1 and in 16 days in case 2, which seemed to represent resolving hematoma. The atypical appearance of these adrenal pseudocysts, especially the changeable pattern of the solid component within the mass, should be kept in mind to ensure a correct preoperative diagnosis.

Abstract
To clarify the phenotypes of various classes of human hematopoietic progenitor cells, we used a multicolor staining protocol in conjunction with CD34 and a newly developed mouse antihuman c-kit proto-oncogene product (KIT) monoclonal antibody (MoAb). We characterized three cell fractions in CD34+ cells that express KITlow and KIThigh cells in addition to KIT- cells. A clonogenic assay showed that most granulocyte-macrophage colony-forming cells (GM-CFC) were present in CD34+KIThigh populations, whereas erythroid burst-forming cells (BFU-E) were detected mainly in the CD34+KITlow population. CD34(+)-KIT- fraction contained a small number of BFU-E. Morphologic analysis showed that blast-like cells were more enriched in the CD34+KITlow fraction. KITlow cells contained CD34+CD38- cells that were considered to be very primitive progenitor cells, as determined by a replating assay. To clarify the biologic differences between both fractions, we examined the more primitive progenitor cell functions by assessing long-term culture-initiating cells (LTC-IC) on the stromal cells. At week 2, more CFC recovered from the culture in the fraction initiated with a CD34+KIThigh population. However, more LTC-IC were present during weeks 5 to 9 in the CD34+KITlow population. These results indicate that primitive progenitors are more enriched in the KITlow population and that the KIThigh population contains many GM-committed progenitor cells. We also showed that anti-KIT MoAb inhibited the ability of CD34+ cells to generate CFC on the stromal layer in the LTC system. This suppressive effect was more evident in the generation of BFU-E by CD34+KITlow cells. Moreover, we confirmed that CD34+KIThigh cells emerged from CD34+KITlow cells during coculture with allogeneic stromal cells or from liquid culture in the presence of stem cell factor (SCF), interleukin-6, and erythropoietin. These results emphasize the pivotal role of the KIT and SCF interaction in hematopoiesis and indicate that KITlow cells are more primitive than KIThigh cells.

Abstract
To investigate how c-kit and c-kit ligand play a role in the function of hematopoietic stem cells, we determined the expression of c-kit in sorted human hematopoietic stem cells, CD34+CD33- cells and CD34+CD33+ cells. CD34+ cells constituted approximately 1% of the population of gated bone marrow cells and contained colony-forming cells. Two-color analysis by a fluorescence-activated cell sorter (FACS) revealed that about one-third to one-half of the total CD34+ cell population were positive for the CD33 antigen. To analyze the relative accumulation of c-kit mRNA in sorted cells, we used the reverse transcription-polymerase chain reaction (RT-PCR) method, followed by Southern blot analysis. There was a linear relationship between the amount of input RNA and products amplified in the range of 10(3) to 10(5) cells. Using this procedure, we carried out an analysis of c-kit mRNA expression in CD34+CD33-, CD34+CD33+, CD34-CD33+, and CD34-CD33- cells. Enhanced expression for c-kit mRNA was observed solely in CD34+CD33- cells. In contrast, flow cytometry shows that c-kit protein was expressed most abundantly in CD34+CD33+ cells. Colony-forming cells were generated on a human stromal cell layer for 5 weeks initiated with CD34+CD33- cells but not with CD34+CD33+ cells. During co-culture with stromal cells, CD34+CD33- cells differentiated into CD34+CD33+ cells. From these findings, it is concluded that CD34+CD33+ cells are direct progenies of CD34+CD33- cells. In this differentiation pathway, the expression of c-kit mRNA decreased and the c-kit protein increased.

Abstract
The CT findings of invaginated mesentery in adult intussusception were analyzed in 12 patients (three patients with four small bowel intussusceptions and nine patients with nine large bowel intussusceptions). In all small bowel intussusceptions, the neck was located near the superior mesenteric artery and vein (SMA & SMV) and showed a medial opening, and the vessels in the neck showed a continuity to the left side of SMA & SMV. In most of the large bowel intussusceptions, the neck was located distant from SMA & SMV, and the vessels in the neck did not show continuity to SMA & SMV. The difference in CT findings between small and large bowel intussusception is attributed to the difference in mesenteric anatomy; the small bowel and its mesentery move freely in the peritoneal cavity, whereas the large bowel is partially fixed to the retroperitoneum.
