Objective: To evaluate the spectrum of isolated hollow visceral perforations in patients presenting with abdominal blunt trauma. Method: The observational, analytical, cross-sectional study was conducted at the surgical ward of Mayo Hospital, Lahore, Pakistan from July 1, 2020, to June 31, 2021, and comprised patients who presented in the emergency department after blunt trauma to abdomen without any open wound. Findings of hollow visceral injury were confirmed on exploration laparotomy. Data was analysed using SPSS 26. Results: Of the 216 patients, 173(80.9%) were male and 43(19.9%) were female. The overall mean age was 42±9.7 years. Most of the blunt trauma abdomen cases were caused by motor vehicle accidents 59(27.3%). The most common hollow viscus affected was jejunum 42(19.4%), followed by transverse colon 29(13.4%). The most common type of injury observed was single complete disruption of hollow viscus 74(34.2%). Conclusion: The most common hollow organ affected by blunt trauma to the abdomen was jejunum, followed by transverse colon, and motor vehicle accidents were the major cause of these injuries.

Pneumoperitoneum caused by a perforated appendix is extremely rare. We encountered a case of a 24 years old male presented in the emergency department of EAST surgical ward of MAYO Hospital Lahore with a history of epigastric pain for 10 days, which later became generalized. Chest X-ray showed free air under the right hemidiaphragm. On the basis of clinical examination and radiological correlations diagnosis of duodenal ulcer perforation was made. On exploration of abdomen through midline incision it was found to be a perforated appendix at its tip. The body and base of the appendix was normal. No per operative and postoperative complications were encountered and the patient discharged on the second postoperative day. Biopsy of appendix showed acute inflammation of appendix.
