Background Postoperative complications (POCs) are significant concerns to surgeons because of their possible fatality or long-term disabilities. This study aimed to investigate the early POCs of gastrointestinal surgery and its associated factors in Yemeni patients treated in a teaching hospital in Sana'a University referral hospital. Method A retrospective cross-sectional study from June 2016 to June 2020 was conducted at Al-Kuwait Teaching Hospital, Sana'a University, Yemen. The patients' characteristics, causative factors, primary treatment, and POCs were recorded from their medical profiles. Univariate analysis was utilized to identify the risk factors associated with gastrointestinal POCs within 30 postoperative days. Results The 30-postoperative day mortality was 3.6%, and major POCs occurred in 22 (20%) patients. There is no statistically significant relationship between POCs and age, sex, smoking, khat chewing, comorbidities (diabetes mellitus, anemia, jaundice, heart disease), emergency cases, drain insertion, and operative time (p ˃ 0.05). There was a significant relationship between POCs and preoperative poor nutritional status, high American Society of Anesthesiologists (ASA) grade, need for blood transfusion, major abdominal surgeries, iatrogenic injury, small bowel resection, reoperation, and history of the previous laparotomy (p ≤ 0.05). Conclusion There is a significant relationship between preoperative poor nutritional status, high ASA, need for blood transfusion, major abdominal surgeries, reoperation, small bowel resection, iatrogenic injury, previous laparotomy, and POCs across different gastrointestinal procedures. These factors should be assessed when auditing surgical outcomes.

Giant hydronephrosis owing to ureteropelvic junction obstruction is a rare condition characterized by the accumulation of more than 1000 ml of urine in the pyelocaliceal system. It could mimic the other benign cystic kidney disease or other causes of abdominal mass in radiologic images. We reported a 16-year-old female who presented with three months of abdominal pain and gradual abdominal mass ingrowth. Abdominal computed tomography scan showed a giant left cystic mass favored hydronephrosis secondary to ureteropelvic junction obstruction. The patient underwent a left nephrectomy, and more than 12 litters of turbid urine were suctioned from the affected kidney. In conclusion, giant hydronephrosis is an infrequent entity and should be considered in the differential diagnosis of large cystic abdominal masses. The treatment is determined by the underlying cause and the visual appeal of the affected kidney.

Cecal duplication cyst is a rare congenital malformation with a few reported adult cases. We present a 23-year-old man who presented with low-grade fever, constipation, and right lower quadrant pain for three days. An abdominal computed tomography scan showed a cystic mass of 8.8x7.5x6 cm adjoining to the posterior wall of the cecum. The patient underwent abdominal laparotomy, and a right hemicolectomy was performed with resection of the duplication cyst. The histopathological study confirmed the diagnosis of a non-communicating cecal duplication cyst. In conclusion, it is essential to include cecal duplication cyst in the differential diagnosis of the acute abdomen to guarantee the best treatment strategy.
