Transverse colonic volvulus (TCV) is a serious condition with a mortality rate of up to 33%. It is very rare, especially in children. Despite its rarity, surgeons should have a high index of suspicion and include it in the list of differential diagnoses, especially in patients with developmental delays and associated uncommon syndromes. Resection and anastomosis, whether as a one-stage or two-stage procedure, proved to be the best treatment options for children. Since prompt identification and management are vital, this paper presents useful information on the presentation, treatment, and outcome of this case report.

This case report explores the complex diagnostic dilemma between the Chilaiditi sign and the pneumoperitoneum. The patient presented with chronic complaints of vague abdominal pain, abdominal distension, and breathlessness. A chest X-ray indicated an elevated right hemidiaphragm with transverse colon interposition, leading to the diagnosis of Chilaiditi's sign. Subsequent imaging, including abdominal ultrasound and contrast-enhanced computed tomography, revealed a large non-enhancing multilobulated multicystic mass adherent to the anterior wall of the uterus, raising suspicions of malignancy. Managed by gynecologists, the patient underwent a total abdominal hysterectomy, mass excision, and bilateral salpingo-oophorectomy. The discussion delves into Chilaiditi's sign, its historical context, and its complex pathophysiology involving intestinal, hepatic, and/or diaphragmatic components. Various anatomical and functional factors contributing to this condition are explored. This case highlights the importance of considering the Chilaiditi sign in patients with radiologic evidence of subdiaphragmatic air. It emphasizes the need for timely and accurate diagnosis to differentiate it from more severe conditions like pneumoperitoneum. Such consideration aids in optimizing management strategies and preventing unnecessary investigations.

Internal hernias are difficult to diagnose clinically, and normal cross-sectional imaging has been documented in many patients. Transmesenteric hernias from congenital defects or prior abdominal surgery are most common. A 46-year-old previously healthy female presented to the emergency department with acute onset nausea and vomiting eight years after a right ureteral transection during a laparoscopic hysterectomy, with a delayed ureterolysis and reimplantation into the bladder. Rectal contrast CT scan demonstrated a partial large bowel obstruction that was unclear if it was due to an underlying mass, stricture, or internal herniation. The patient was taken for exploratory laparotomy which demonstrated redundant transverse colon herniated under the mobile right ureter; an extended right hemicolectomy was performed. This report describes alteration of retroperitoneal anatomy creating a potential space for colonic herniation and emphasizes that clinical suspicion must remain high for patients presenting with obstructive or partially obstructive symptoms.

UNLABELLED
Schwann cells are found in the peripheral nervous system and can sometimes appear as benign hamartoma lesions in various parts of the body. Although rare in the gastrointestinal (GI) tract, they have been observed in the colon. Recently, mucosal Schwann cell hamartomas of the GI tract have been studied, and it was discovered that they had yet to be investigated up to 2009. In this context, we present the case of a 60-year-old man who was found to have lesions in the transverse colon during a routine colonoscopy. No further investigations were conducted since these lesions have not been associated with any risk of malignancy transformation and have not been linked to any inherited syndromes.
LEARNING POINTS
Mucosal Schwann cell hamartomas are rare types of polyps that can be found anywhere in the gastrointestinal tract.They are benign lesions not usually associated with any inherited syndrome and they are usually found incidentally by endoscopy.These polyps are benign and might not require further follow-up once diagnosed.

BACKGROUND
Colonic varices are a rare gastrointestinal anomaly often associated with portal hypertension. Arteriovenous fistula (AVF) in the inferior mesenteric artery (IMA) region is even rarer. Diagnosis and treatment of these entities present unique challenges, especially when the IMA is involved.
CASE PRESENTATION
A 48-year-old man with a history of cholecystectomy presented with after a positive fecal occult blood test. Investigations revealed varices from the splenic flexure to the transverse colon and suspected AVF in the IMA region. Given the high risk and low efficacy of endoscopic and radiological interventions, laparoscopic sigmoidectomy was performed. This surgical approach successfully addressed both the AVF and the associated varices.
CONCLUSION
This case underscores the importance of surgical intervention for AVF and colonic varices in the IMA region, particularly when other treatment options pose high risks and have limited efficacy. The favorable postoperative outcome in this case highlights the effectiveness of carefully chosen surgical methods when managing such complex and rare conditions.

Cancer (including pancreatic cancer) can develop following a infection within one year of tuberculosis infection. However, it is unclear whether tuberculosis infection increases the risk of developing adenosquamous carcinoma of the pancreas (ASCP), an extremely rare cancer with a poorer prognosis than pancreatic ductal adenocarcinoma (PDAC). Herein, we report a case of rapid growing ASCP discovered upon a resection for neck tuberculous lymphadenitis. The patient was a 57-year-old woman. An excisional biopsy of the swollen right neck lymph nodes revealed tuberculous lymphadenitis. One month after the biopsy, an abdominal computed tomography scan showed a 2.0 cm (diameter) ischemic tumor in the pancreatic tail. The tissue obtained using endoscopic ultrasonography-guided fine-needle aspiration led to the pathological diagnosis of ASCP. Two months after the biopsy, the tumor had grown to 3.5 cm (diameter), and invasion of the stomach and colon was suspected. Distal pancreatectomy, splenectomy, partial gastrectomy, and transverse colectomy were performed. The final diagnosis was ASCP (4.7 cm, pT3, pN0, cM0, and pStage IIA). Postoperative adjuvant combination chemotherapy combined with antituberculosis drugs was administered orally. We report the first case of rapidly growing adenosquamous carcinoma resected from the pancreas in association with tuberculous lymphadenitis. Additional evidence is needed to confirm that tuberculosis infection increases the risk of developing pancreatic adenosquamous cell carcinoma because its potential role in promoting squamous metaplasia is unclear.

A 52-year-old male patient was diagnosed with transverse colon cancer and synchronous stage IVA para-aortic lymph node (PALN) metastases (cT3N1bM1a of the lymph node). Six courses of mFOLFOX6 plus bevacizumab were administered as neoadjuvant chemotherapy. Computed tomography showed shrinkage of the primary tumor and PALN metastases. Extended right hemicolectomy, D3 lymph node dissection, and PALN dissection were performed. A pathologic examination indicated that the tumor had completely changed and comprised necrotic tissue with no viable cells. Therefore, it was considered that mFOLFOX6 plus bevacizumab resulted in a pathologic complete response. Postoperatively, six courses of mFOLFOX6 were administered. Six years postoperatively, the patient did not exhibit any signs of recurrence. There have been few reports of pathologic complete response after neoadjuvant therapy and resection for colon cancer with synchronous PALN metastases. This report describes a unique case involving a pathologic complete response with long-term survival after mFOLFOX6 plus bevacizumab and radical resection, including PALN dissection. Preoperative mFOLFOX6 plus bevacizumab followed by radical resection and adjuvant mFOLFOX6 therapy was safe and resulted in a good outcome. This regimen should be considered for advanced colon cancer with PALN metastases.

BACKGROUND
During laparoscopic left hemicolectomy procedures, a previously overlooked consistently thick blood vessel within the gastrocolic ligament near the splenic hilum may contribute to post-operative bleeding complications. The purpose of this study was to investigate the identification and management of the previously overlooked blood vessel.
METHODS
This is a retrospective descriptive study of patients undergoing laparoscopic left colectomy for splenic fexure cancer conducted at a national gastrointestinal surgery centre in China. Consecutive patients with splenic fexure cancer who underwent laparoscopic left colectomy using our"five-step process"(n = 34) between January 2021 and July 2023 were included.
RESULTS
The vessels can be effectively exposed using the aforementioned "five-step process." It was observed that the overlooked vessels consistently present in all patients were identified as the omental branch of the left gastroepiploic artery and vein.
CONCLUSION
We have identified the origin of previously overlooked blood vessels and recommended a safe method for their management. This may offer advantages to colorectal surgeons performing laparoscopic left colectomy for splenic flexure cancer.

Case Reports in Gastroenterology 2024Crohn's disease (CD) is complicated by intestinal strictures and fistula formation; however, intestinal perforation is relatively rare.
INTRODUCTION
Crohn's disease (CD) is complicated by intestinal strictures and fistula formation; however, intestinal perforation is relatively rare.
CASE PRESENTATION
Following a traffic accident in the evening, a 39-year-old woman experienced abdominal pain that worsened the following morning and was taken to the emergency department. She had a 17-year history of CD and eight endoscopic balloon dilations for descending colonic strictures. She presented with a high fever of 40.0°C, along with tenderness and rebound pain throughout her abdomen, with the most substantial point being in the lower left abdomen. Computed tomography showed thickening of the descending colon wall, increased fat concentration around the wall, and a slight presence of air in the mesentery near the intestinal wall. We diagnosed the patient with generalized peritonitis due to traumatic penetration of the mesentery of the descending colon and performed emergency surgery. Intraoperative observation of the abdominal cavity with a laparoscope revealed purulent ascites but no apparent perforation or edematous mesentery, with white moss and redness in the descending colon. This prompted the decision to perform peritoneal lavage drainage and a transverse colonic double colostomy. The postoperative course was favorable, and the patient was discharged from the hospital on the postoperative day 14. Four months after discharge, colostomy closure was performed.
CONCLUSION
Relatively minor trauma in patients with CD can result in colon injury. An injured bowel is usually accompanied by active lesions due to CD; however, caution is required, as endoscopic balloon dilatation without accompaniment may be a background factor.

BACKGROUND
Gastric intramural hematoma is a rare disease. Here we report a case of spontaneous isolated gastric intramural hematoma combined with spontaneous superior mesenteric artery intermural hematoma.
CASE PRESENTATION
A 75-years-old man was admitted to our department with complaints of abdominal pain. He underwent a whole abdominal computed tomography (CT) scan in the emergency department, which showed extensive thickening of the gastric wall in the gastric body and sinus region with enlarged surrounding lymph nodes, localized thickening of the intestinal wall in the transverse colon, localized indistinct demarcation between the stomach and transverse colon, and a small amount of fluid accumulation in the abdominal cavity. Immediately afterwards, he was admitted to our department, and then we arranged a computed tomography with intravenously administered contrast agent showed a spontaneous isolated gastric intramural hematoma combined with spontaneous superior mesenteric artery intermural hematoma. Therefore, we treated him with anticoagulation and conservative observation. During his stay in the hospital, he was given low-molecular heparin by subcutaneous injection for anticoagulation therapy, and after discharge, he was given oral anticoagulation therapy with rivaroxaban. At the follow-up of more than 4 months, most of the intramural hematoma was absorbed and became significantly smaller, and the intermural hematoma of the superior mesenteric artery was basically absorbed, which also confirmed that the intramural mass was an intramural hematoma.
CONCLUSION
A gastric intramural hematoma should be considered, when an intra-abdominal mass was found to be attached to the gastric wall. Proper recognition of gastric intramural hematoma can reduce the misdiagnosis rate of confusion with gastric cancer.
