Review
Colorectal cancers comprise a large percentage of tumors worldwide, and transverse colon cancer (TCC) is defined as tumors located between hepatic and splenic flexures. Due to the anatomy and embryology complexity, and lack of large randomized controlled trials, it is a challenge to standardize TCC surgery. In this study, the current situation of transverse/extended colectomy, robotic/ laparoscopic/open surgery and complete mesocolic excision (CME) concept in TCC operations is discussed and a heatmap is conducted to show the evidence level and gap. In summary, transverse colectomy challenges the dogma of traditional extended colectomy, with similar oncological and prognostic outcomes. Compared with conventional open resection, laparoscopic and robotic surgery plays a more important role in both transverse colectomy and extended colectomy. The CME concept may contribute to the radical resection of TCC and adequate harvested lymph nodes. According to published studies, laparoscopic or robotic transverse colectomy based on the CME concept was the appropriate surgical procedure for TCC patients.

Colonic volvulus is one of the most common causes of bowel obstruction. It could occur in different parts of the colon. The sigmoid is the most common part, but it rarely occurs in the transverse colon because of the colon's anatomical features. So, simultaneous sigmoid and transverse colon volvulus is a rare phenomenon that could endanger patients' lives due to its rarity, ischemia, necrosis of the colon wall, and the lack of a definite algorithm to approach this disease. So, it is essential to consider this disease as one of the most important differential diagnoses in patients with abdominal pain and distention. In this article, a 45-year-old male presented to the surgical ward with severe prolonged abdominal pain, diagnosed with simultaneous sigmoid and transverse colon volvulus during laparotomy.

PURPOSE
To observe and count the probability of presence and the anatomy of the vessel arising the inferior margin of the pancreas and traveling within the transverse mesocolon, and analyze its clinical significance.
METHODS
Patients who underwent radical operation for transverse colon cancer or descending colon cancer from January 2020 to November 2021 and a nonspecific cadaver were included in this study. We observed and recorded intraoperatively for the probability of presence and the anatomy of the vessel arising the inferior margin of the pancreas and traveling within the transverse mesocolon. And its property was determined by tissue slice.
RESULTS
A total of 84 patients were included, of which, the vessel was observed in 72 (85.7%) patients, and its property was confirmed by tissue slice of one patient after surgery. The vessel was also observed in a nonspecific cadaver. Originating from transverse pancreatic artery, often one, occasionally two, rarely three vessels arose the inferior margin of pancreas and supplied the left transverse colon. Artery and vein parallel ran, and it was difficult to separate them due to their small diameter, but the vessels may thicken under certain conditions for increasing blood supply.
CONCLUSION
The vessel, which is not yet reported and named in the literature, can be called the subpancreatic transverse colon vessel, which has a high probability of presence in humans and may be of great significance to human physiological anatomy, surgery, and oncology, and deserves recognition and attention from surgeons.

BACKGROUND
Laparoscopic and robotic surgery for transverse colon cancer are difficult due to complex fusion of the foregut and midgut and variation of the vessels of the transverse colon. Although the vessels of the right colon have been investigated, middle colic artery (MCA) variation and the relationship with vessels around the transvers colon are unknown. We investigated variation of the MCA using computed tomography angiography (CTA) and cadaver specimen and the relationship between the superior mesenteric vein (SMV) and MCA using CTA. The classification of vessels around the transverse colon may lead to safer and reliable surgery.
METHODS
This study included 505 consecutive patients who underwent CTA in our institution from 2014 to 2020 and 44 cadaver specimens. Vascular anatomical classifications and relationships were analyzed using CT images.
RESULTS
The MCA was defined as the arteries arising from the superior mesenteric artery (SMA) that flowed into the transverse colon at the distal ends. The classifications were as follows: type I, branching right and left from common trunk; type II, the right and left branches bifurcated separately from the SMA; and type III, the MCA branched from a vessel other than the SMA. Type II was subclassified into two subtypes, type IIa with one left branch and type IIb with two or more left branches from SMA. In the CTA and cadaver studies, respectively, the classifications were as follows: type I, n = 290 and n = 31; type IIa, n = 211 and n = 13; type IIb, n = 3 and n = 0; and type III, n = 1 and n = 0. We classified the relationship between the MCA and left side of the SMV into three types: type A, a common trunk runs along the left edge of the SMV (n = 173; 59.7%); type B, a right branch of the MCA runs along the left edge of the SMV (n = 116; 40.0%); and type C, the MCA runs dorsal of the SMV (n = 1; 0.3%).
CONCLUSIONS
This study revealed that The MCA branching classifications and relationship between the SMV and MCA. Preoperative CT angiography may be able to reliably identify vessel variation, which may be useful in clinical practice.

INTRODUCTION
Colonic volvulus is a common cause of large bowel obstruction with the sigmoid colon most commonly affected. Volvulus of the transverse colon is an uncommon occurrence. Rarer still is a transverse colon volvulus developing after surgery for a sigmoid colon volvulus. Early diagnosis is critical as delay in detection and intervention is associated with the risk of complications - perforation, peritonitis, and death.
CASE PRESENTATION
We report the case of an 86-year-old man who presented with features of large bowel obstruction 14 months following a sigmoid colectomy for a sigmoid colon volvulus.
CONCLUSION
A metachronous transverse colonic volvulus is uncommon. Preoperative diagnosis is challenging as there are no defining radiographic features compared to the volvulus of the sigmoid colon with the classical omega sign. Most cases are diagnosed intra-operatively. Bowel resection and anastomosis in a single stage is a safe option.

INTRODUCTION AND IMPORTANCE
Transverse colon volvulus is a rare cause of colonic obstruction accounting for 1-3 % of colonic volvuli due to the short mesentery and hepatic and splenic attachments. Previous mobilisation of the flexures and conditions resulting in chronic dilatation of the colon predispose to the condition. The risk of mortality is high, ranging from 11 to 20 % highlighting the need for early diagnosis and intervention.
CASE PRESENTATION
We present a case of a 90-year-old male who was referred with a large bowel obstruction with a transition at the splenic flexure and the liver rotated to the left upper quadrant. The patient was taken to the theatre and an emergency laparotomy was performed with findings of a transverse colon volvulus. The liver was initially found in the left upper quadrant and was freely mobile in the upper abdomen consistent with an absence of the hepatic ligament. A subtotal colectomy was performed. Unfortunately, the postoperative course was complicated by a cardiac event and the patient died on postoperative day six.
CLINICAL DISCUSSION
Absence of hepatic ligaments is a rare cause of transverse colon volvulus which has only been described in one previous case report. Diagnosis of transverse colon volvulus can be challenging and early operative intervention with colectomy is required to minimise mortality.
CONCLUSION
This case illustrates an unusual cause of transverse colon volvulus secondary to the absence of the hepatic ligaments and stresses the need for early diagnosis and intervention due to the high mortality associated with this condition.

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.

Review
The transverse colon has anatomical peculiarities in the middle position between the foregut and the midgut. Because the transverse colon harbors a flexure at both ends, mobilization of the transverse colon can be especially challenging compared with other colons. Although transverse colon cancer is relatively uncommon, an optimal surgical management for transverse colon cancer must be established. In transverse colon cancer, proximity to the pancreas and variation in arterial and venous anatomy make radical resection more difficult. Dissection of lymph nodes around the middle colic vessels is a critical step in transverse colon cancer resection. The proximity of the middle colic vessels to the superior mesenteric vessels contributes to the complexity of this step, making it challenging for less-trained surgeons. For these reasons, patients with transverse colon cancer were not included in most landmark studies that compared laparoscopic surgery with open surgery. More radical operations, such as subtotal colectomy or extended right or left hemicolectomy, can be performed for transverse colon cancer to secure an adequate lymphadenectomy. Such cancers have also been treated with limited segmental colectomies, such as right, transverse, or left colectomy. Currently, there is still a lack of standardized definitions and procedures. Therefore, it is time to discuss and establish optimal surgical treatments for transverse colon cancer.
