Colorectal juvenile polyp as a pathologic entity was first described by Verse. These non-neoplastic lesions are most commonly found in children and infants, while in older children after the age of 14 and adults are a rare phenomenon. A 75-year-old female underwent colonoscopy. There was a pedunculated polyp in the transverse colon. Complete endoscopic electroresection of this polyp was performed and the polyp was sent for histopathologic analysis. Macroscopically, the polyp was described as a fragment of irregular round shape, size of about 2.5x2x1 cm, with fine-grained, reddish surface, showing dark red color on serial sections. Histologic examination of the polyp showed some irregularly distributed glands, some of which were cystically dilated. All glandular formations were coated with normal intestinal epithelium. The surface of the polyp was partially eroded and replaced by non-specific cellular granulation tissue. There were some signs of hemorrhagic infarction in the stroma of the polyp. Histopathologic examination indicated that histopathologic characteristics of this polyp corresponded to juvenile polyp. Juvenile polyps are very rarely found in adults. Therefore, we describe a case of this patient in her eighties with juvenile polyp localized in the transverse colon.

BACKGROUND
Studies evaluating the outcomes after laparoscopic resections of transverse colon cancers are scant. This manuscript aimed to compare surgical and oncological outcomes after laparoscopic (Lap) and open procedures for transverse colon carcinomas.
METHODS
All consecutive patients who underwent resection for a cancer located in the transverse colon between 2003 and 2019 were reviewed. Patients were categorized according to the surgical approach (Lap versus open) and groups were compared. Outcome measures were the short-term results, complications and functional recovery; moreover, recurrence-free survival (RFS) and overall survival (OS) rates were compared overall and after propensity score matching (PSM) based on age, sex, ASA classification, BMI, carcinoembryonic antigen (CEA) level, use of postoperative chemotherapy, location of tumour, stage and grading, operation time, blood loss and complications.
RESULTS
Of 248 transverse resections reviewed, 146 (81 Lap and 65 open) were selected for data analysis. Blood loss, fluid intake and the incidence of wound infection were significantly lower and the hospital stay was significantly shorter in the Lap group (P < 0.001). The operation time and incidence of complications (Clavien-Dindo classification grade 3 or above) did not differ significantly between the two groups. Mean follow-up was of 75.4 months in the Lap group and 78.6 months in the open group. Regression analyses showed that OS was associated with the postoperative carcinoembryonic antigen (CEA) level (hazard ratio 1.18 (95 per cent c.i. 1.10 to 1.27); P < 0.001), BMI (hazard ratio 0.81 (95 per cent c.i. 0.68 to 0.96); P = 0.017), operation time (hazard ratio 0.99 (95 per cent c.i. 0.97 to 1.00; P = 0.010), and postoperative chemotherapy (hazard ratio 0.27 (95 per cent c.i. 0.08 to 0.96); P = 0.042), while RFS was associated with the postoperative CEA level (hazard ratio 1.13 (95 per cent c.i. 1.07 to 1.20); P < 0.001). PSM selected 42 patients for data comparison of long-term results, and showed no significant differences between groups (RFS: P = 0.530; OS: P = 0.561).
CONCLUSION
Lap and open resections for transverse colon cancer provided similar outcomes in terms of severe post-operative complication and long-term results.

It remains controversial whether elderly patients with transverse colon cancer present worse prognoses. Our study utilized evidence from multi-center databases to evaluate the perioperative and oncology outcomes of radical resection of colon cancer in elderly and nonelderly patients. In this study, we analyzed 416 patients with transverse colon cancer who underwent radical surgery from January 2004 to May 2017, including 151 elderly (aged ≥ 65 years) and 265 nonelderly (aged < 65 years) patients. We retrospectively compared the perioperative and oncological outcomes between these 2 groups. The median follow-up in the elderly and nonelderly groups was 52 and 64 months, respectively. There were no significant differences in the overall survival (OS) (P = .300) and disease-free survival (DFS) (P = .380) between the elderly and nonelderly groups. However, the elderly group had longer hospital stays (P < .001), a higher complication rate (P = .027), and fewer lymph nodes harvested (P = .002). The N classification and differentiation were significantly associated with OS based on univariate analysis, and the N classification was an independent prognostic factor for OS based on multivariate analysis (P < .05). Similarly, the N classification and differentiation were significantly correlated with the DFS based on univariate analysis. However, multivariate analysis indicated that the N classification was an independent prognostic factor for DFS (P < .05). In conclusion, the survival and surgical outcomes in elderly patients were similar to nonelderly patients. The N classification was an independent factor for OS and DFS. Even though elderly patients with transverse colon cancer present a higher surgical risk than nonelderly patients, performing radical resection in elderly patients can be an appropriate choice for treatment.

Colonic volvulus may infrequently occur in the transverse colon, and synchronous double volvulus is a rarely reported phenomenon in the literature. Additionally, intestinal volvulus is a rare but serious complication that has been reported in scleroderma and systemic lupus erythematosus (SLE) patients. We report a 26-year-old patient with a history of scleroderma-SLE overlap syndrome who presented with an acute abdomen. CT imaging revealed a transverse colon volvulus and a cecal bascule (cecal volvulus). To our knowledge, this is the first reported case of synchronous double volvulus of the transverse colon and cecum. Additionally, this is the second reported case of transverse colon volvulus occurring in a patient with scleroderma and the first case in a patient with scleroderma-SLE overlap syndrome.

Pathological and perioperative outcomes of extracorporeal versus intracorporeal anastomosis in laparoscopic transverse colon cancer resection: retrospective multicentre study.
BACKGROUND
The aim of this study was to compare the pathological and perioperative outcomes of extracorporeal versus intracorporeal anastomosis after laparoscopic transverse colon cancer resection.
METHODS
In this retrospective study, patients from seven institutions in China who underwent laparoscopic resection of transverse colon cancer between 2019 and 2021 were selected and included. Either extended right hemicolectomy or transverse colectomy/extended left hemicolectomy was performed. The clinical characteristics and the pathological and perioperative outcomes were compared between patients undergoing extracorporeal or intracorporeal anastomosis. Resection margin lengths were measured on formalin-fixed specimens and an inadequate margin was defined as less than 4.2 cm between the division and the tumour. The outcome of interest was the prevalence of specimens with an inadequate margin. Length of incision, bowel function recovery, hospital stay, early postoperative pain (first day after surgery), 30-day complications, and nodal harvest were investigated as secondary outcomes.
RESULTS
Of 411 patients treated during the study interval, 370 patients with transverse colon cancer were included (23.2 per cent treated with intracorporeal anastomosis and 76.8 per cent treated with extracorporeal anastomosis). The prevalence of specimens with inadequate margins was lower in the intracorporeal anastomosis group compared with the extracorporeal anastomosis group in patients undergoing extended right hemicolectomy (P = 0.045) and in patients undergoing transverse colectomy/extended left hemicolectomy (P = 0.030). In multivariate analysis, extracorporeal anastomosis (OR 2.94 (95 per cent c.i. 1.33 to 6.49), P = 0.008) and transverse colectomy/extended left hemicolectomy (OR 1.75 (95 per cent c.i. 1.03 to 2.96), P = 0.038) were independent risk factors for specimens with an inadequate margin. Intracorporeal anastomosis was associated with a shorter incision length (P < 0.001), an earlier recovery of bowel function (P = 0.035), a shorter postoperative hospital stay (P = 0.042), less early postoperative pain (P < 0.001), a longer specimen length (P = 0.042), a longer resection margin (P = 0.007), and a greater lymph node harvest (P = 0.036). There was no statistically significant difference in 30-day complications.
CONCLUSION
Patients with transverse colon cancer have better perioperative outcomes, fewer margins of less than 4.2 cm, and larger lymph node harvests when the anastomosis is performed intracorporeally. Further studies are needed to confirm these findings.

American Journal of Translational... 2023To compare the efficacy of laparoscopy versus laparotomy in the treatment of transverse colon cancer.
OBJECTIVE
To compare the efficacy of laparoscopy versus laparotomy in the treatment of transverse colon cancer.
METHODS
Data from 100 patients with transverse colon cancer treated in our hospital from January 2018 to December 2020 were retrospectively analyzed in this study. According to the treatment methods, these patients were assigned into two groups: a laparotomy group (n=50) and a laparoscopy group (n=50). The intraoperative parameters, postoperative recovery, incidences of complications, postoperative pain, quality of life (QoL) score, postoperative serum inflammatory cytokine (hs-CRP, TNF-α, and IL-6) levels, and prognostic nutritional index (PNI) were analyzed and compared between the two groups.
RESULTS
There was no significant difference in number of resected lymph nodes between the two groups. The operation time and intraoperative bleeding in the laparoscopy group were significantly less than those in the laparotomy group (P<0.05). The hospital stay, duration of gastrointestinal function recovery, and time of first postoperative flatus in the laparoscopy group were significantly shorter than those in the laparotomy group (all P<0.001). Moreover, the incidence of overall complications in the laparoscopy group was significantly lower than that in the laparotomy group (P<0.05). Compared with those in the laparotomy group, the VAS score was obviously lower and the QoL score was significantly higher in the laparoscopy group (all P<0.001). Patients in the laparoscopy group exhibited lower levels of postoperative hs-CRP, TNF-α and IL-6 in contrast to those in the laparotomy group (P<0.05). In additional, there was no significant difference in the PNI level before surgery between two groups. After surgery, the PNI level in the laparoscopy group was obviously higher than that in the laparotomy group (P<0.001).
CONCLUSION
Laparoscopy is superior to laparotomy in treatment of transverse colon cancer through achieving better intraoperative outcomes, promoting postoperative recovery, reducing the incidence of complications and inflammatory reactions, alleviating postoperative pain, and improving therapeutic effects.

BACKGROUND
Pseudomyxoma peritonei (PMP) is a rare neoplasm involving the peritoneum. Most PMPs are low-grade appendicular mucinous neoplasms (LAMNs). There have been no reports of PMP originating from a transverse colonic mucinous adenocarcinoma and causing metastatic mucinous adenocarcinoma. . We report a 46-year-old woman who presented with a right abdominal mass of more than 4-month duration. Transverse colonic mucinous adenocarcinoma, PMP, and ovarian metastatic mucinous adenocarcinoma were diagnosed. The patient's diet was normal, and she had no abdominal pain or bloating. The abdomen mass increased in the month before treatment. After chemotherapy, the transverse colon mass and ovarian giant cyst were resected and about 2000 mL of gelatinous tumor tissue was removed. Postoperative histology confirmed PMP from the transverse colonic mucinous adenocarcinoma, ovarian metastatic mucinous adenocarcinoma, and mesocolon metastatic cancer. Multiple lung metastases appeared 8 months after surgery. The patient died 29 months after surgery because of an inability to eat and poor nutrition. A systematic literature review of the management and outcome of all known similar cases is also presented.
CONCLUSIONS
This is the first report of PMP originating from a transverse colonic mucinous adenocarcinoma. It was diagnosed during resective surgery, involved ovarian metastasis, and survival was short. We did an extensive literature review in order to describe the clinical characteristics, histopathological findings, genetic profile, and potential treatments of PMP caused by nonappendiceal mucinous adenocarcinoma.

Comparative Study
Mid-transverse colon cancer and extended versus transverse colectomy: Results of the Italian society of surgical oncology colorectal cancer network (SICO CCN) multicenter collaborative study.
INTRODUCTION
Transverse colon cancer (TCC) is poorly studied, and TCC cases are often excluded from large prospective randomized trials because of their complexity and their potentially high complication rate. The best surgical approach for TCC has yet to be established. The aim of this large retrospective multicenter Italian series is to investigate the advantages and disadvantages of both hemicolectomy and transverse colectomy in order to identify the best surgical approach.
MATERIALS AND METHODS
This was a retrospective cohort study of patients with mid-transverse colon cancer treated with a segmental colon resection or an extended hemicolectomy (right or left) between 2006 and 2016 in 28 high-volume (more than 70 procedures/year) Italian referral centers for colorectal surgery.
RESULTS
The study included 1529 patients, 388 of whom underwent a segmental resection while 1141 underwent an extended resection. A higher number of complications has been reported in the segmental group than in the extended group (30.1% versus 23.6%; p 0.010). In 42 cases the main complication was the anastomotic leak (4.4% versus 2.2%; p 0.020). Recovery outcomes also showed statistical differences: time to first flatus (p 0.014), time to first mobilization (p 0.040), and overall hospital stay (p < 0.001) were significantly shorter in the extended group. Even if overall survival were similar between the groups (95.1% versus 97%; p 0.384), 3-year disease-free survival worsened after segmental resection (78.1% versus 86.2%; p 0.001).
CONCLUSIONS
According to our results, an extended right colon resection for TCC seems to be surgically safer and more oncologically valid.

A 50-year-old male was referred to a Gastroenterology appointment after a screening colonoscopy with a 25mm exophytic lesion, with a depressed central area, on the transverse colon. Histologic examination of the biopsy specimen showed low-grade dysplasia. The patient was submitted to a new colonoscopy and what was seen was a flat lesion with central depression, with no lift-sign (Figure 1a and 1b) and, therefore, endoscopic resection was not performed. New endoscopic biopsies were taken and showed no dysplasia.
