Cecal Perforation Following Intraperitoneal Abscess after Anti-tubercular Therapy: A Case Report.

Abdominal tuberculosis is defined as infection of gastrointestinal tract, peritoneum, abdominal solid organs, and/or abdominal lymphatics constituting approximately 12% of extra-pulmonary tuberculosis cases. Intestinal perforation is an acute presentation of abdominal tuberculosis. Intestinal perforation can occur before or at the beginning of anti-tubercular therapy. It is considered to be a paradoxical reaction if it occurs during or after treatment. Intestinal perforation is uncommon but serious and life-threatening as complication-mortality rate secondary to perforation are estimated to be >30%. We present a case of an 18-year-old female who developed cecal perforation following an intraperitoneal abscess after completion of anti-tubercular therapy for intestinal tuberculosis. She was a known case of intestinal tuberculosis. She had undergone pigtail catheterisation for an intraperitoneal abscess and completed 18 months of anti-tubercular therapy after which she developed cecal perforation. A paradoxical response was observed following the completion of anti-tubercular therapy. Early diagnosis and treatment reduce the complications and mortality rates of cecal perforation due to abdominal tuberculosis. Keywords: case reports; cecum; intestinal perforation; tuberculosis.

Strategies in the Management of Pancreatic Ductal Adenocarcinoma Involving Aberrant Right Hepatic Artery Arising From the Superior Mesenteric Artery.

Introduction The prevailing guidelines do not include the involvement of an aberrant right hepatic artery (aRHA) arising from the superior mesenteric artery in classifying borderline resectable pancreatic ductal adenocarcinoma (BR PDAC). Our novel classification aims to distinguish different entities depending on the location and degree of tumor involvement of aRHA and propose a strategy to manage tumor involvement of aRHA in PDAC. Material and methods The patients who underwent pancreaticoduodenectomy (PD) from September 1, 2018, to August 31, 2022 were analyzed retrospectively, and patients with aRHA were included in the study. Depending on the radiological data, arterial involvement of the aRHA was classified into group I with proximal involvement of the aRHA up to 2 cm from its origin in the superior mesenteric artery (SMA) and group II with distal involvement of aRHA beyond 2 cm from its origin in SMA. In addition, the resection margin status was correlated with the technique employed for managing the tumor-involved artery. Results A total of 122 patients underwent PD during the study period. Eight patients were identified to have tumor involvement of the aRHA arising from the SMA. Among the five patients in group I, three patients who had upfront surgery showed R1 resection regardless of periarterial divestment or resection/reconstruction of the involved artery, whereas R0 resection was achieved in the two patients who had neoadjuvant therapy. All patients in group II had R0 resection regardless of receiving neoadjuvant therapy. There were no significant morbidity and mortality in our series. Conclusion The aRHA should be considered in the classification of BR PDAC. Management strategies should be tailored based on the location and the degree of tumor involvement in the aRHA. We advocate neoadjuvant therapy for proximal involvement and upfront surgery for distal involvement of aRHA to achieve good oncological clearance.
