Perioperative Blood Transfusions and Anastomotic Leak After Colorectal Surgery for Cancer in an Australian Hospital.

PURPOSE: Peri-operative blood transfusion has been identified as a risk factor for anastomotic leak in recent studies, but little is known about which patients are at risk for blood transfusion. This study aims to assess the relationship between blood transfusion and anastomotic leak and factors predisposing to leak in patients undergoing colorectal cancer surgery. METHODS: This retrospective cohort study was conducted in a tertiary hospital in Brisbane, Australia, between 2010 and 2019. A total of 522 patients underwent resection of colorectal cancer with primary anastomosis with no covering stoma and the prevalence of anastomotic leak was compared between those who had had perioperative blood transfusion(s) and those who had not. RESULTS: A total of 19 of 522 patients undergoing surgery for colorectal cancer had developed an anastomotic leak (3.64%). 11.3% of patients who had had a perioperative blood transfusion developed an anastomotic leak whereas 2.2% of patients who had not had a blood transfusion developed an anastomotic leak (p = 0.0002). Patients undergoing procedure on their right colon had proportionally more blood transfusions and this approached statistical significance (p = 0.06). Patients who received a greater quantity of units of blood transfusion prior to their diagnosis of anastomotic leak were more likely to develop an anastomotic leak (p = 0.001). CONCLUSION: Perioperative blood transfusions are associated with a significantly increased risk of an anastomotic leak following bowel resection with primary anastomosis for colorectal cancer.

Gallbladder volvulus with preoperative and intraoperative imaging.

Volvulus of the gallbladder is one of the rarest conditions to affect the gallbladder, however, it should remain an important differential. Typically, it is diagnosed in elderly women, but it has also been reported in children and men. The lack of unique distinguishing features make diagnosis difficult to distinguish between other gallbladder pathology such as acute cholecystitis; however, delayed recognition or non-operative management is associated with higher mortality. We present the case of a 92-year-old woman who presented with this pathology, had diagnosis established preoperatively and was successfully treated with a cholecystectomy.

Fistulating diverticular disease masquerading as a peri-anal abscess: a laparoscopic approach to management.

We present a rare case of complicated sigmoid diverticulitis presenting as a peri-anal abscess from an extra-sphincteric fistulous tract. This presentation of a colocutaneous peri-anal abscess is extremely rare, with only a handful of cases described in the literature. Most are managed with an open sigmoid colectomy, however, this case was successfully managed laparoscopically. It highlights the need to consider extra-levator causes of peri-anal abscess, such as pelvic sepsis causing fistulating disease, and to consider early magnetic resonance imaging if there is clinical suspicion of underlying pathology. It also demonstrates that a safe and potentially less morbid outcome is possible via laparoscopic approach when compared to traditional open surgical approach.

Expectant management of traumatic intussusception.

Mesenteric injuries and traumatic intussusception are rare surgical presentations following blunt trauma, with potentially life-threatening complications. Diagnosis relies on high clinical suspicion and judicious use of imaging in trauma. Literature suggests that these presentations should always be managed operatively for diagnostic clarity, manual reduction of intussusception and, if indicated, resection of involvement segment. However, in the setting of a stable patient with a reassuring examination, this may not be necessary. This case presents the successful expectant management of a traumatic mesenteric haematoma acting as a pathologic lead point for small bowel intussusception.

An Exceptional Case of Ileocolic Intussusception Secondary to Burkitt's Lymphoma: What Variations Are There in the Presentation and Management of Those Patients Who Approach Adolescence?

Intussusception is a common cause of abdominal pain among the paediatric population with up to 10% of cases occurring secondary to a pathological lead point. Burkitt's lymphoma (BL) is a highly malignant and rapidly growing B-cell neoplasm which in extremely rare cases can present as intussusception. We report a case in an otherwise healthy 15-year-old male who presented with atypical abdominal pain. Imaging subsequently indicated an ileocolic intussusception, and given that the suspicion of a pathological lead point mandates a laparotomy and bowel resection, he proceeded to surgery. The histopathology confirmed Burkitt's lymphoma as the aetiology responsible for this intussuscepted mass. A detailed discussion including a systematic review of all previous case reports explore the diagnostic dilemma of intussusceptions secondary to BL. This case report aims to highlight the clinical challenges in establishing such a diagnosis and an appreciation for the subtle variations in clinical features, as well as the differences in management between infants and adolescents.

Expect the Unexpected: Torsion of the Gallbladder, a Rare Cause for Acute Cholecystitis.

Gallbladder torsion is a rare cause for acute cholecystitis. Gallbladder torsion is unlikely to respond to conservative management and requires urgent surgical intervention. We report a case of an 85-year-old female with gallbladder torsion. She presented with a clinical picture consistent with acute cholecystitis. Radiological findings showed signs that elude to the diagnosis and intra-operative findings showed a complete torsion with a free-floating gallbladder. This case highlights the need to have a high index of suspicion for gallbladder torsion as a differential diagnosis for right upper quadrant (RUQ) pain apart from the typical calculous acute cholecystitis, especially in high risk groups such as thin, elderly females. Prompt decision for cholecystectomy is necessary and is likely to result in a good outcome.

Laparoscopic repair of a right diaphragmatic hernia in a post-partum lady.

Traumatic diaphragmatic injuries (TDI) are often challenging to diagnose. Research suggests that no single diagnostic study is sensitive or specific enough to identify such an injury, unless there is established herniation of intrabdominal contents. It is a rare cause of small bowel obstruction, which carries a substantial mortality rate. This report describes a case of a 41-year-old pregnant female who presented with irretractable vomiting and abdominal pain secondary to a delayed presentation of right-sided TDI. The most accepted mechanism regarding TDI is due to sudden elevation in the pleuroperitoneal pressure gradient. This case is unusual given its mechanism of injury during pregnancy and its right-sided location. She underwent laparoscopy which facilitated successful reduction of the hernial and closure of the defect. Postoperatively, she made an excellent recovery and was discharged within a few days. This report aims to increase the awareness amongst surgeons.
