Gastrocolic fistula (GCF) is defined as an abnormal pathological communication between the epithelialized mucosal layers of the stomach and colon. In rare cases, complications following gastric bypass surgery, such as leakage or complicated marginal ulcers, may contribute to the development of a GCF. The laparoscopic approach for managing GCF involves a one-stage procedure that includes resection of the fistula and reconstruction of the gastrointestinal tract. [ABSTRACT FROM AUTHOR]

Background: A gastrocolic fistula is an unusual communication between the colon and the stomach. Although colon cancer is the most common malignant cause of gastrocolic fistula in the Western world, the incidence of gastrocolic fistula due to colon cancer is 0.3% in operated cases. Case presentation: A 68-year-old man presented with anorexia, general malaise, weight loss, and vomiting of fecal matter. Investigations revealed that the patient had a large nonmetastatic splenic flexure tumor that was diagnosed as colon cancer and had invaded the stomach and pancreas. An upper gastrointestinal series confirmed a gastrocolic fistula. Left hemicolectomy, distal gastrectomy, distal pancreatectomy, and splenectomy were performed. Histology revealed transverse colon cancer, which was UICC stage (8th edition) pT4bN1bcM0 pStage IIIC. Adjuvant chemotherapy was not performed. There was no recurrence or metastasis one year after surgery. We reviewed 17 cases including our case of a gastrocolic fistula caused by colon cancer. Neoadjuvant chemotherapy was not given to any of the patients, and en bloc resections were conducted in all cases. Adjuvant chemotherapy was given to almost all of the patients. There was no recurrence or metastasis. Conclusions: For gastrocolic fistula caused by advanced colon cancer, secure en bloc surgical resection was the initial treatment in all 17 reported cases including the present case, and adjuvant chemotherapy may contribute to a better prognosis.

This article discusses a case of a 2-year-old girl who ingested multiple buckyballs, small magnetic metallic spheres, which resulted in a gastrocolonic fistula. The girl had no symptoms, but the foreign bodies were discovered through routine X-rays. Gastroscopy revealed the presence of three buckyballs in the stomach, while laparoscopy confirmed the presence of four balls in the transverse colon. Prompt medical attention and surgical intervention were necessary to remove the buckyballs and prevent severe gastrointestinal damage. Caregivers are advised to keep buckyballs out of children's reach to prevent accidental ingestion. [Extracted from the article]

Background: Management of the leak is determined by the duration of the leak from the initial surgery. Acute leaks occurring less than 72 hours after surgery are best managed with reoperation and primary repair. Intermediate leaks, greater than 72 hours but less than 12 weeks, can be managed with non-operative management in non-septic patients. When non-operative management fails beyond 12 weeks the leak is considered a chronic fistula which are best treated with definitive operative management. Sub-total gastrectomy with Roux-En-Y reconstruction with gastrojejunostomy, has been reported with resolution of the fistula in over 90% of cases. Objectives: To demonstrate the operative management of chronic sleeve gastrectomy leaks. Methods: A 37-year-old male with a history of a sleeve gastrectomy, developed a chronic fistula between the distal gastric staple line and the transverse colon. After non-operative management failed the patient was taken to the operating room for a diagnostic laparoscopy with plans to perform a revision. A fistula between the distal sleeve staple line and the transverse colon was identified. The gastroesophageal junction was dissected and inspected, there was no fistula at the angle of His. A near total gastrectomy was then performed leaving a small gastric pouch. The colonic side of the fistula was oversewn. Roux-En-Y reconstruction was then performed. Results: No leak identified at four-month follow-up. Conclusion: Leak after sleeve gastrectomy can be difficult to manage. Chronic leaks do not respond well to non-operative management. Partial gastrectomy with Roux-En-Y reconstruction is a technically challenging option with good results. [ABSTRACT FROM AUTHOR]

A 72-year-old woman was admitted to our hospital complaining of loss of weight, general fatigue, and upper abdominal pain. Barium studies suggested that a fistula was present between the proximal transverse colon and the stomach which originated from a carcinoma of the colon. A plain computed tomography (CT) scan confirmed the presence of a gastrocolic fistula. A two-thirds distal gastrectomy and right hemicolectomy with a resection of a bulky tumor in the mesocolon were performed en bloc. Histological examination revealed a well-differentiated adenocarcinoma of the transverse colon which was involved with the wall of the stomach. We were able to obtain information on 14 previous cases of gastrocolic fistula originating from transverse colon cancer in the Japanese literature, including the present case. The most common symptom was abdominal pain (64%). A preoperative diagnosis of fistula was confirmed in 10 of the 11 cases examined by barium studies. A plain CT and a CT scan after the barium studies may also be helpful in detecting fistula formation. A fistula between the carcinoma of the middle or distal transverse colon and the stomach was found in 13 of 14 cases, but not in our case. Only one case lived longer than 9 years, even though a surgical resection was possible in 9 of 11 cases. [ABSTRACT FROM AUTHOR]

Gastrocolic fistula is a rare complication of percutaneous endoscopic gastrostomy. It is most frequently discovered after replacement of the gastrostomy tube. The symptoms are severe diarrhea, failure to thrive, recurrent Gram-negative pulmonary infections, and feculent vomiting. [ABSTRACT FROM AUTHOR]
