This study aimed to explore the risk factors of clinically relevant pancreatic fistulas (PF) after laparoscopic pancreaticoduodenectomy (LPD). The clinical data of 80 patients who underwent pancreaticoduodenectomy in our hospital were retrospectively analyzed. ⋯ Results from the multivariate logistic regression analysis showed that the pancreatic duct diameter (P = .002) and pancreatic texture (P = .016) were significant risk factors for clinically relevant PF. Based on this study, the pancreatic duct diameter and pancreatic texture are independent risk factors for clinically relevant PF after LPD.

Gastric stump carcinoma (GSC) is very exceptional and little known after Whipple procedure, and its diagnosis and treatment are extremely difficult to handle. ⋯ The development of GSC several years after Whipple procedure is uncommon. This is the first case from China that has received international attention. Early diagnosis is crucial. Surgery is considered to be the most effective treatment for GSC after Whipple procedure if long-term survival is possible and surgical risks are controllable.

Case Reports
Two cases of spontaneous rupture of the uterine artery in the perinatal period: A case report.
Uterine artery spontaneous rupture is a rare but potentially life-threatening complication during pregnancy and puerperium. The lack of typical symptoms makes it difficult to diagnose, which can result in serious consequences for both the mother and fetus. ⋯ Uterine artery spontaneous rupture is a rare but potentially life-threatening complication that may present with atypical symptoms. Early diagnosis and prompt surgical intervention are crucial in preventing serious complications for both the mother and fetus. Clinicians should maintain a high level of suspicion for this condition when evaluating patients presenting with unexplained symptoms or signs of peritoneal irritation during pregnancy and puerperium.

Case Reports
Rare perivascular epithelial cell tumor of the colon 18F-FDG PET/CT imaging: A case report.
Neoplasms with perivascular epithelioid cell differentiation (PEComas) are mesenchymal tumors that rarely occur in the colon. Here, we report the occurrence of a malignant PEcoma in the colon using 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT). ⋯ Malignant perivascular epithelioid cell tumors originating in the colon are extremely rare, and our report suggests that PEComa should be considered as a differential diagnosis for 18F-FDG gastrointestinal malignancies. Additionally, 18F-FDG PET/CT may play a key role in the staging and extent of lesions in intestinal malignancies.

Gastric malignancies constitute the sixth most common cancer with regards to incidence and have the fifth most mortality rates. Extended lymph-node dissection is the surgical modality of choice while treating advanced stage gastric cancer. It is yet a topic of debate, whether or not the amount of positive lymph nodes after a pathological examination following the surgical intervention is of prognostic value. ⋯ We calculated cutoff value of 0.09 with, sensitivity is 76.32% for positive to total number of lymph nodes ratio, whereas specivity applies for 64.10%, positive predictive value for 58% and negative predictive value for 80.6%. Positive lymph node ratio has a prognostic value in terms of predicting the prognosis of the patients with gastric adenocarcinoma following a curative gastrectomy. This might in long term contribute to the prognostic analysis of patients if integrated in the current staging system.
