Solitary Fibrous Tumors of the Mesocolon: A Report of Two Cases and Review of Literature.

Solitary fibrous tumors (SFTs) are an uncommon group of neoplasms. The visceral pleura is the most common site of origin of these tumors. The colonic mesentery is an unusual site of origin of SFTs. A pre-operative diagnosis of SFT is challenging as there are no pathognomonic clinical or radiological signs. Most patients reported thus far were diagnosed post-operatively with the aid of immunohistochemical markers. Complete surgical excision is the treatment of choice for SFTs. Recurrences are uncommon. However, they can occasionally show aggressive behavior. In this report, we describe two cases of rare colonic mesentery SFTs.

An audit of Complicated Choledochal Cysts- 15-years' experience at a tertiary care center.

PURPOSE: Complicated choledochal cysts (CDC) have a variable presentation, and their management differs from an uncomplicated CDC. They are infrequently reported. We present our 15 years of experience in the management of complicated CDC. METHODOLOGY: We reviewed the data of patients with CDCs managed at a tertiary level center from 2005 to 2020 from a prospectively maintained database. RESULTS: Of 215 patients with CDC, 123 patients presented with complicated CDC. The median age of complicated CDC was 31 years with a female preponderance (62.6%). The most common type of CDC associated with complications was type I (69.1%), followed by type IVA (29.3%). The Complicated CDC was presented as cholangitis with or without cystolithiasis (n = 45), cystolithiasis and hepatolithiasis(n = 44), malignancy(n = 10), complications associated with incomplete cyst excision (n = 10), acute pancreatitis (n = 8), chronic pancreatitis(n = 8), portal hypertension (n = 6), spontaneous rupture (n = 4), gastric outlet obstruction (n = 1). These patients were managed as a one-stage approach (52.03%) and a two-stage approach (47.96%). On univariate and multivariate analysis, increasing age, prolonged duration of symptoms, and presence of abnormal pancreaticobiliary ductal junction (APBDJ) were significantly associated with complicated CDC. CONCLUSION: The management of complicated CDC varied depending on the associated pathology, many of them required a staged approach. Increasing age, prolonged duration of symptoms, and presence of APBDJ were significantly associated with complicated CDC.

Primary Hepatic Choriocarcinoma with Pregnancy: A Diagnostic and Therapeutic Challenge.

Choriocarcinoma occurs mainly in the gonads, but an extragonadal origin has been reported, albeit infrequently. Primary hepatic choriocarcinoma (PHC) is a rare malignancy, with only 11 cases reported. Most cases reported were in males, with none reported in pregnant females. A 23-year-old primigravida presented with a large liver lesion involving the right lobe of the liver at 28 weeks of pregnancy. Preoperative imaging was suggestive of hepatocellular carcinoma. She underwent a non-anatomical resection of the liver lesion. Surprisingly, her postoperative histopathology revealed a diagnosis of PHC. Her blood workup showed elevated beta human chorionic gonadotrophin. She underwent a termination of her pregnancy at 32 weeks. Before initiating adjuvant chemotherapy four weeks after surgery, a whole-body PET scan revealed multiple bi-lobar liver and pelvic deposits. After a multidisciplinary team discussion, she was started on adjuvant chemotherapy. She is currently under regular follow-up, seven months post-surgery. PHC, one of the vascular lesions of the liver, poses a diagnostic and therapeutic challenge, warranting a multidisciplinary approach.

Is central pancreatectomy an effective alternative to distal pancreatectomy for low-grade pancreatic neck and body tumors: A 20-year single-center propensity score-matched case-control study.

Backgrounds/Aims: Central pancreatectomy (CP) is associated with a higher rate of postoperative pancreatic fistula (POPF), and it is less preferred over distal pancreatectomy (DP). We compared the short- and long-term outcomes between CP and DP for low-grade pancreatic neck and body tumors. Methods: This was a propensity score-matched case-control study of patients who underwent either CP or DP for low-grade pancreatic neck and body tumors from 2003 to 2020 in a tertiary care unit in southern India. Patients with a tumor >10 cm or a distal residual stump length of < 4 cm were excluded. Demographics, clinical profile, intraoperative and postoperative parameters, and the long-term postoperative outcomes for exocrine and endocrine insufficiency, weight gain, and the 36-Item Short Form Survey (SF-36) quality of life questionnaire were compared. Results: Eighty-eight patients (CP: n=37 [cases], DP: n=51 [control]) were included in the unmatched group after excluding 21 patients (meeting exclusion criteria). After matching, both groups had 37 patients. The clinical and demographic profiles were comparable between the two groups. Blood loss and POPF rates were significantly higher in the CP group. However, Clavien-Dindo grades of complications were similar between the two groups (p = 0.27). At a median follow-up of 38 months (range = 187 months), exocrine sufficiency was similar between the two groups. Endocrine sufficiency, weight gain, SF-36 pain control score, and general health score were significantly better in the CP group. Conclusions: Despite equivalent clinically significant morbidities, long-term outcomes are better after CP compared to DP in low-grade pancreatic body tumors.

A case series of choledochal cyst with pancreatic divisum: A rare association.

Choledochal cysts (CC) are congenital cystic dilations of the biliary tree usually associated with abnormal pancreaticobiliary ductal junction (APBDJ), but its association with pancreatic divisum has been rarely described. We encountered four cases of CC associated with pancreatic divisum (PD). Three had Type 3 PD and one had Type 1 PD. Two cases presented with pancreatic complications, with one case requiring preoperative minor papilla sphincterotomy for recurrent pancreatitis. The association of CC with PD is infrequent, and the variable presentation alters management strategy. PD may be one of the factors responsible for complications associated with CC.
