In 114 cases of the transverse colon isolated from cadavers (50 male, 64 female), anatomical examinations of the arterial system of the colon were performed. Arteriograms were obtained after dissecting and contrasting the colonic vessels with Mixobar contrast. In one case, on arteriography of the colon with its mesentery isolated from a 55-year-old male cadaver, a rare anatomical variant was found. The third mesenteric artery originated directly from the aorta-halfway between the superior and inferior mesenteric arteries and ascended obliquely in the direction of the hepatic flexure of the colon. Supply area of the artery was typical for the middle colic branch of the superior mesenteric artery: the distal segment of the ascending colon and the transverse colon. Such a variation, although very rare, may have particular impact on diagnosis and even the method and range of surgery.

BACKGROUND
While anastomotic leakage, recurrent laryngeal nerve paralysis, and pneumonia are well-known complications of esophagectomy, the incidence of hiatal hernia after esophagectomy for carcinoma has been reported to only be between 0.6 and 10%. We report a very rare case of hiatal hernia with transverse colon rupture in the mediastinum after esophagectomy in a 65-year-old woman.
CASE PRESENTATION
The patient underwent definitive chemoradiotherapy for clinical stage IIA esophageal squamous cell carcinoma and salvage esophagectomy with gastric tube reconstruction through a posterior mediastinum route for residual carcinoma. Three years after the initial surgery, two metastatic nodules in the lateral and posterior segments of the liver were detected on follow-up CT and were treated with oral anticancer drugs. After 6 months, the patient was readmitted for anorexia. Upon admission, computed tomography revealed an ileus caused by a hiatal hernia. Emergent operative repair was performed; an incarcerated herniation of the transverse colon was perforated in the mediastinum, and partial transverse colon resection and colostomy were performed. Intensive care was required to control septic shock after surgery, and the patient was discharged on the 53rd postoperative day.
CONCLUSIONS
Cases of hiatal hernia with digestive tract prolapsing into the mediastinum after esophagectomy with reconstruction through posterior mediastinum are rare but potentially life-threatening complications.

Patients with acute colorectal obstruction due to malignancy in the right-sided colon are treated with primary resection and anastomosis. However, considering the generally poor status and prognosis, less-invasive, palliative treatment is desirable, particularly for unresectable malignancies. An ileostomy is useful, but the patient must manage the stoma, which worsens the quality of life. We developed a palliative surgical procedure, termed the "Separation surgery of the right-sided colon," for treating an obstruction due to unresectable right-sided colon cancer. We identified and divided the ileum and the transverse colon and anastomosed the upper ileum to the lower transverse colon. Then, we created a mucous fistula with the loose ends of the lower ileum and the upper transverse colon. We performed this procedure in five patients. Stoma pouches were unnecessary. No comorbidities were observed, including anastomotic leakage. The "Separation surgery of the right-sided colon" was useful as palliative surgery.

Sigmoid volvulus is a common cause of colon obstruction, while volvulus of the transverse colon rarely causes bowel obstruction. The occurrence of transverse colon volvulus after resection of the sigmoid colon volvulus is extremely rare. This report presents a 73-year-old man who presented with abdominal pain and peritonitis. The patient underwent exploratory laparotomy, and sigmoid volvulus and cecum perforation were confirmed. A right hemicolectomy, end-to-side ileotransverse colon anastomosis for the cecal perforation, and sigmoidectomy with end-colostomy (Hartmann's procedure) for the sigmoid volvulus were performed. A month later, the patient returned to the emergency room with abdominal distention and the blockage of colostomy. Abdominal CT revealed a transverse colon volvulus. A transverse and descending colon resection and ileorectal anastomosis were performed. The patient's condition was stable at the time of discharge from the hospital. The management of metachronous colon volvulus should include surgical intervention. If patients are not diagnosed immediately, their condition may deteriorate dramatically because of bowel infarction or peritonitis. It is essential to highlight this case, as many surgeons may not have attended a transverse colon volvulus after sigmoid volvulus, which might lead to high morbidity or mortality. Overall, metachronous colonic volvulus must be considered in the differential diagnosis of bowel obstruction, particularly in patients with significant risk factors.

INTRODUCTION
Previous randomized controlled trials demonstrated similar oncological outcomes between laparoscopic-assisted (LA) and open (OP) colectomy; however, patients with transverse colon cancer were not analyzed. The aim of this study was to confirm the oncological safety and the advantages of the short- and long-term results of LA surgery for transverse colon cancer in comparison to OP surgery.
MATERIALS AND METHODS
The study data were retrospectively collected from the databases of four hospitals. Patients with transverse colon cancer who underwent LA or OP R0 or R1 resection were registered.
RESULTS
Among the 204 patients, 149 underwent OP colectomy and 55 underwent LA colectomy. The median follow-up period was 43 months. The rate of conversion to OP resection was 7.3%. The 5-year overall survival rate of the LA group was higher than that of the OP surgery group for all-stage patients (97.5% vs. 91.1%, P = 0.108), and it was similar in Stage II and Stage III patients (94.1% vs. 94.2%, P = 0.510). The LA group had significantly lower blood loss and a significantly longer operative time in comparison to the OP surgery group. Furthermore, the postoperative hospital stay was significantly shorter (9 vs. 13 days, P = 0.001) and the incidence of Grade ≥III complications was lower in the LA group (3.7% vs. 14.8%, P = 0.031).
CONCLUSION
We concluded that LA surgery for transverse colon cancer is oncologically safe and yields better short-term results in comparison to OP surgery.

INTRODUCTION
Colonic volvulus is defined as a torsion of a part of the colon causing large bowel obstruction by strangulation which may lead to ischemia and then necrosis. The synchronous occurrence of a sigmoid colon and transverse colon volvulus is exceptional. We describe a case of synchronous sigmoid and transverse volvulus in a patient with a qualitative systematic review of this condition.
PRESENTATION OF THE CASE
This is a 74-year-old patient with a history of chronic constipation, who consulted for bowel obstruction. Plain abdominal radiography showed diffuse gas distension of the colon with the absence of rectal gas. An exploratory laparotomy was performed and showed sigmoid colon volvulus associated with synchronous transverse colon volvulus without bowel necrosis. A left hemicolectomy with loop colostomy was performed. The restoration of bowel continuity was done 3 weeks. The post-operative course was uneventful.
DISCUSSION
The occurrence of a simultaneous sigmoid and transverse colonic volvulus is an exceptional situation. Due to the rarity of this clinical entity, the literature concerning its description is sparse and the treatment options are poorly codified. There are no guidelines in the treatment and a tailored approach should be used for each patient.
CONCLUSION
The dual location of strangulation makes this situation a major surgical emergency with a high risk of gangrene and septic shock. Colectomy with delayed anastomosis should be preferred in the treatment.

A femoral hernia is one of the groin hernias with a high chance of incarceration and strangulation due to its narrow neck. Here, we report a case of transverse colon incarceration. A 65-year-old female patient presented with groin mass that failed to reduce and a dragging pain. Elective open femoral herniorrhaphy was done with the finding of viable incarcerated massive momentum along with transverse colon. Femoral hernias have a female-to-male ratio of about 10:1. Postmenopausal, increasing age, and constipation were some of the risk factors identified in our patient. Various types of organs can be found in the femoral hernia sac but one of the rarely reported organ was found in our case: a transverse colon. Femoral hernia with a large bulky soft mass can get incarcerated easily but relatively less prone to strangulation.

BACKGROUND
The novel 2019 coronavirus disease (COVID-19), which is caused by infection with the severe acute respiratory syndrome coronavirus 2, has spread rapidly around the world and has caused many deaths. COVID-19 involves a systemic hypercoagulable state and arterial/venous thrombosis which induces unfavorable prognosis. Herein, we present a first case in East Asia where an acute superior mesenteric artery (SMA) occlusion associated with COVID-19 pneumonia was successfully treated by surgical intervention.
CASE PRESENTATION
A 70-year-old man presented to his local physician with a 3-day history of cough and diarrhea. A real-time reverse transcriptase-polymerase chain reaction test showed positive for COVID-19, and he was admitted to the source hospital with the diagnosis of moderate COVID-19 pneumonia. Eight days later, acute onset of severe abdominal pain appeared with worsening respiratory condition. Contrast CT showed that bilateral lower lobe/middle lobe and lingula ground glass opacification with distribution suggestive of COVID-19 pneumonia and right renal infarction. In addition, it demonstrated SMA occlusion with intestinal ischemia suggesting extensive necrosis from the jejunum to the transverse colon. The patient underwent an emergency exploratory laparotomy with implementing institutional COVID-19 precaution guideline. Upon exploration, the intestine from jejunum at 100 cm from Treitz ligament to middle of transverse colon appeared necrotic. Necrotic bowel resection was performed with constructing jejunostomy and transverse colon mucous fistula. We performed second surgery to close the jejunostomy and transverse colon mucous fistula with end-to-end anastomosis on postoperative day 22. The postoperative course was uneventful and he moved to another hospital for rehabilitation to improve activities of daily living (ADLs) on postoperative day 45. As of 6 months after the surgery, his ADLs have completely improved and he has returned to social life without any intravenous nutritional supports.
CONCLUSIONS
Intensive treatment including surgical procedures allowed the patient with SMA occlusion in COVID-19 pneumonia to return to social life with completely independent ADLs. Although treatment for COVID-19 involves many challenges, including securing medical resources and controlling the spread of infection, when severe abdominal pain occurs in patients with COVID-19, physicians should consider SMA occlusion and treat promptly for life-saving from this deadly combination.

Sarcoidosis is a multisystem chronic inflammatory disease of unknown etiology, characterized by non-caseating granulomas. Sarcoidosis has the potential to involve every tissue in the body, which mainly affect the lymphatic system and lungs; gastrointestinal system, and particularly the colon, is an extremely rare location. We report the case of a 64-year-old male with history of pulmonary and cutaneous sarcoidosis diagnosed with neoplasm in the hepatic flexure of the colon and a polyp with high-grade dysplasia in the transverse colon by colonoscopy after a positive fecal occult blood test. The case was presented to a multidisciplinary committee and it was decided to perform a total laparoscopic colectomy and ileorectal anastomosis with histopathological evidence of infiltrating adenocarcinoma and intestinal sarcoidosis with non-caseating granulomas in the appendix, terminal ileum, colon and locoregional lymph nodes. The relationship between colon cancer and sarcoidosis is controversial, with studies showing a possible increased risk of cancer in patients with sarcoidosis, relating it to the chronic proinflammatory state of the disease. In these cases, lymph node involvement is especially important when assessing tumor extension studies, and may lead to changes in staging and, as a consequence, in the therapeutic approach.

Observational Study
AIM
This study aimed to investigate whether the site of the tumour within the right colon affects survival in patients who underwent right colectomy for colon cancer.
METHODS
An observational retrospective longitudinal study was performed in patients who underwent right colectomy for non-metastatic, invasive right-sided colon cancer. Patients were categorized into two groups based on tumour location: (i) caecum and ascending colon; (ii) hepatic flexure and proximal transverse colon. Demographic and clinical features were characterized, and a survival analysis was performed.
RESULTS
Of the 198 patients enroled in the study, 134 (67.8%) had caecal or ascending colon cancer and 64 (32.3%) had hepatic flexure or transverse colon cancer. Seventy (35.4%) were female and the mean age at the time of surgery was 71.6 (SD 11.4). The groups were comparable with respect to the number of lymph nodes sampled, the pTNM stage, the histological differentiation grade and the likelihood of patients receiving adjuvant chemotherapy. Recurrence rate was nearly twice as high in the hepatic flexure and proximal transverse colon group (12.5% vs 6.7%), but this difference was not statistically significant (p = 0.174). Kaplan-Meier analysis showed no differences in disease-free (p = 0.255) and overall survival (p = 0.258) between the groups.
CONCLUSION
In our population, specific location of right-sided colon cancers does not appear to have an influence on survival. Further investigation is needed to determine if tumour subsite has an impact on the recurrence rate, and whether it should be considered in defining prognosis and treatment.
