Surgical Outcomes in 62 Patients with Ulcerative Colitis: A Retrospective, Single-Center Study from Poland.

BACKGROUND Surgery continues to play an important role in the treatment of ulcerative colitis (UC), which is one of the most common inflammatory diseases of the colon and rectum. This retrospective study from a single center in Poland aimed to evaluate surgical outcomes in 62 patients with ulcerative colitis. MATERIAL AND METHODS The study enrolled 62 patients (36 men [58.1%], 26 women [41.9%]), mean age 52.69±16.84 (range, 19-96) years who underwent surgical treatment of UC during the period 2001-2020. The mandatory inclusion criteria were patients with UC, who underwent total intra-abdominal colectomy (n=22, 46.8%), proctocolectomy (n=25, 53.2%), or left-sided hemicolectomy (n=8, 12.9%). The primary endpoint was postoperative death, and secondary endpoints were long hospitalization (>15 days), complications, and relaparotomy. RESULTS Postoperative mortality was observed in 8 (12.9%) patients. Older age and low albumin level were associated with longer hospitalization time (P=0.004 and P<0.001, respectively). High C-reactive protein (CRP) level (P=0.003), high CRP/albumin ratio (P=0.023), and malnourishment (P=0.026) were risk factors for complications. Malnutrition (P=0.026), older age (P=0.031), high CRP level (p<0.001), high CRP/albumin ratio (P=0.014), arterial hypertension (P=0.012), and urgent surgeries (P=0.021) were associated with higher risk of postoperative death. Patients who had undergone previous surgeries were more likely to need relaparotomy (P=0.022). CONCLUSIONS Preoperative nutritional status was an important factor associated with postoperative outcomes in patients with ulcerative colitis. Correction of malnutrition seems to be a vital part of preoperative preparation.

Comparison of Postoperative Outcomes of Hand-Sewn Versus Stapled Esophago-jejunal Anastomosis During Total Gastrectomy for Gastric Cancer in 72 Patients: A Retrospective, Single-Center Study in Poland.

BACKGROUND Mechanical stapling is a commonly used alternative to hand-sewn technique for esophago-jejunal anastomosis in total gastrectomy (TG). Some studies report reduction in postoperative complications in the stapler group. This retrospective study aimed to compare short- and long-term surgical outcomes between the groups with stapled and hand-sewn esophago-jejunal anastomosis (EJA) during open TG for gastric cancer. MATERIAL AND METHODS The study included 72 adult patients with gastric cancer who underwent TG in the Department of Digestive Tract Surgery in Katowice between May 2018 and December 2021. The patients were divided into 2 groups according to the technique of EJA: stapled (44 cases) or hand-sewn (28 cases). We compared the groups in terms of the duration of the surgery, length of hospital stay, and occurrence of complications (focusing on anastomotic leakage, stricture and abdominal abscess). RESULTS There were no significant differences in duration of the surgery (P=0.6), blood loss (P=0.7), or length of postoperative hospital stay (P=0.2) among the groups. Early postoperative complications rates were 9.1% (4/44) in the stapler group and 17.9% (5/28) in the hand-sewn group (P=0.27). The most frequent complication was anastomotic leakage, with 2 cases in each group (P=0.76). The mean follow-up time was 1.8±0.9 (0.3-3.6) years. During this period the anastomotic stricture occurred in 7 (15.9%) cases with stapled anastomosis and in 5 (17.9%) cases with hand-sewn anastomosis (P=0.52). CONCLUSIONS In this study there were no significant differences in mortality, morbidity, and surgery duration between stapled and hand-sewn esophago-jejunal anastomosis in total gastrectomy.

Skin Metastases of Gastrointestinal Neuroendocrine Tumors - Literature Review.

<b> Introduction:</b> Gastrointestinal neuroendocrine neoplasms arise from cells of the diffuse endocrine system (DES) located in the digestive tract. They are often diagnosed in an advanced stage, when distant metastases appear. Skin metastases of neuroendocrine tumors are extremely rare. </br></br> <b>Aim:</b> The aim of the study was to collect and analyze cases of skin metastases of gastrointestinal neuroendocrine neoplasms. </br></br> <b>Materials and methods:</b> A literature search across PubMed and Medline databases from 1969 up to 2021 was performed. We reviewed English literature according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. The following keywords were used: "neuroendocrine tumor", "neuroendocrine neoplasm", "neuroendocrine carcinoma", "NET", "NEN", "skin and cutaneous metastases", "lymph nodes". The characteristics of patients, grading, tumor localization and other data that was found in publications were assessed. Case reports and case series were included. </br></br> <b>Results:</b> The initial search strategy yielded 14 results in PubMed and 3 in the Medline database. We removed duplicates after we imported the citations with a citation manager. We found 17 publications concerning skin metastases of neuroendocrine neoplasms. The analysis of 18 cases concerned 13 NECs and 5 NETs. In most cases, the metastases are small, painless and located on the scalp or lower extremities. Skin metastases may be the first symptom of the disease. The pancreas is the most common primary tumor site.</br></br> <b>Conclusions:</b> NEN metastases to the skin are often diagnosed with disseminated neoplastic process, which is associated with poor prognosis and high mortality. NET metastases to the skin may occur with an unknown primary site. Skin metastases of neuroendocrine tumors should be considered during the diagnosis of skin tumors.

Evaluation of Risk Factors for Distant and Lymph Node Metastasis of Pancreatic Neuroendocrine Tumors.

Purpose: Metastases of pancreatic neuroendocrine tumors (pNETs) can be found at the time of diagnosis in 20-50% of cases. Small asymptomatic tumors may be left for observation; however, they can metastasize. The aim of the study was to evaluate risk factors for distant and lymph node metastases of pNETs. Patients and methods: One hundred and fourteen patients with postoperatively confirmed pNET were analyzed retrospectively in a single ENETS Center of Excellence. The relationship between location, size, differentiation of the tumor, and occurrence of lymph node and distant metastases was analyzed. Results: pNETs' location was pancreatic head - 38 (33.3%), body or tail - 68 (59.7%), and 8 (7.0%) involved the entire organ. Fifty-six (49.1%) tumors were graded G1, 50 (43.9%) G2, and 8 (7.0%) G3. Seventy-two (63.2%) tumors were ≥2 cm in diameter, and 42 (36.8%) <2 cm. Twenty-two (19.3%) patients had distant metastases and 47 (41.2%) had lymph node metastases. In ≥2 cm tumors distant and lymph node metastases were more frequent (p < 0.05). Distant metastases incidence was significantly higher in distally located tumors (p = 0.01) and in G2 and G3 tumors (p < 0.01). In 9.5% of <2cm tumors, distant metastases were present at diagnosis. Conclusion: Distant metastases are more often found in larger, distally located pNETs grade G2 and G3, while a higher occurrence of lymph node metastases seems to be associated only with larger tumor size. A considerable number of tumors <2 cm in size have distant metastases already at the diagnosis, which might indicate the need for careful qualification of smaller lesions for observation.

A Single-Center Retrospective Study of Selected Clinical Parameters and Intraoperative Fluid Management of Patients Undergoing Pancreatoduodenectomy.

BACKGROUND Pancreatoduodenectomy is an extensive procedure with a very high risk of complications. Appropriate intraoperative fluid therapy is a subject of ongoing debate. The aim of this retrospective study was to analyze the relationship between selected preoperative parameters, intraoperative fluid therapy, and catecholamines administration during pancreatoduodenectomy. MATERIAL AND METHODS From 2011 through 2017, among pancreatoduodenectomies performed at a single university hospital, 192 patients met the inclusion criteria of the study: 105 (54.7%) males and 87 (45.3%) females with a mean age of 60.06 (±11.63) years. Correlations were assessed between sex, age, body mass index (BMI), selected comorbidities, surgery duration, American Society of Anesthesiologists (ASA) Physical Status (PS) scale, preoperative endoscopic retrograde cholangiopancreatography (ERCP) and intraoperative catecholamine administration, intraoperative fluid supply, red blood cell (RBC) concentrate and fresh frozen plasma (FFP) supply, blood loss, and diuresis. RESULTS A need for catecholamines has been shown to be more frequent in smokers (P=0.01), patients with cardiovascular comorbidities (P=0.037), high ASA PS scores (P=0.003), and preoperative ERCP (P=0.011). The need for intraoperative transfusion of RBC concentrate was more frequent in smokers (P=0.005). Surgical time was significantly longer in males (P=0.014). Among females, liberal intraoperative fluid therapy (>7.9 ml/kg/h) was more frequent in patients with thyroid comorbidities (P=0.003). CONCLUSIONS The findings of this retrospective study demonstrate the influence of comorbidities, ASA PS class, and catecholamine use on fluid therapy during pancreatoduodenectomy.

Utility of fistula risk score in assessing the risk of postoperative pancreatic fistula occurrence and other significant complications after different types of pancreatic neuroendocrine tumor resections.

Purpose: This study was performed to evaluate the utility of the fistula risk score (FRS) and its components in predicting the occurrence of postoperative pancreatic fistula and other significant postoperative complications after resections of pancreatic neuroendocrine tumors. Methods: Retrospective analysis of 131 patients operated on for pancreatic neuroendocrine tumors between 2015 and 2021 was performed. The correlation of the FRS scale with the occurrence of postoperative pancreatic fistulas and postoperative complications according to the Clavien-Dindo classification was analyzed; only in 109 cases of distal resections and pancreatoduodenectomies (PD). Results: Soft pancreatic texture and intraoperative blood loss of >700 mL are risk factors for clinically significant pancreatic fistula (P = 0.001 and P = 0.001, respectively) and significant postoperative complications (P = 0.016 and P = 0.001, respectively). Wirsung duct diameter (WDD) was associated only with the occurrence of postoperative pancreatic fistula (P = 0.013). FRS scale is associated with the occurrence of pancreatic fistulas and clinically significant postoperative complications in cases of distal resections and PDs (P < 0.001 and P = 0.005, respectively). Postoperative complications are correlated with the occurrence of fistula type B or C (P < 0.001). Conclusion: Soft pancreatic texture, intraoperative blood loss of >700 mL, and a WDD of ≤3 mm are risk factors for clinically significant postoperative pancreatic fistula. FRS may be applied not only in PDs but also in distal pancreatectomies. Unfortunately, it is not used in total pancreatic resections and enucleations since FRS takes into account the WDD.

A Retrospective Study of Postoperative Outcomes in 98 Patients Diagnosed with Gastrointestinal Stromal Tumor (GIST) of the Upper, Middle, and Lower Gastrointestinal Tract Between 2009 and 2019 at a Single Center in Poland.

BACKGROUND Gastrointestinal stromal tumors (GISTs) arise in the smooth muscle pacemaker interstitial cells of Cajal, or similar cells. The aim of this retrospective study between 2009 and 2019 from a single center in Poland was to assess the selected prognostic factors (location, tumor size, mitotic index, body mass index (BMI), length of hospital stay, age, sex, and coexistent neoplasm) and to investigate postoperative outcomes in 98 patients with GIST of the upper, middle, and lower gastrointestinal tract. MATERIAL AND METHODS Between 2009 and 2019, 98 patients (50 women and 48 men) with an average age of 63.8 years (range from 38 to 90 years) were operated on for GIST in the Department of Gastrointestinal Surgery in Katowice, Poland. Based on the intraoperative and postoperative investigations, the tumor size and mitotic index were determined in each case. RESULTS A statistically significant correlation between age and mitotic index (MI) was found (p=0.02). The higher the MI, the younger the age of the patients. However, regardless of sex, younger patients had a tendency to survive longer. A >60-year-old male patient's probability of survival was around 65% after 40 months. Higher mitotic index was also associated with larger tumor size (p<0.0001). Female patients had a tendency to survive longer than males. CONCLUSIONS The findings from this small retrospective study support the importance of preoperative evaluation and frequent postoperative follow-up for patients with GIST of the gastrointestinal tract, particularly in older male patients, and patients with malignant comorbidities, which are associated with increased mortality.

A giant biliary cyst of Todani IA in a young woman: A case report.

RATIONALE: Biliary cysts (BC) are rare dilatations of various parts of a biliary tract. They account for approximately 1% of all benign biliary diseases. Total cyst excision and Roux-Y hepaticojejunostomy is the treatment method of choice in most patients. In this paper, a novel surgical treatment with the use of internal biliary and pancreatic catheters was presented. PATIENT CONCERNS: A 21-years-old woman with a giant choledochal cyst of Todani IA type presenting with abdominal pain, nausea, fever and palpable abdominal mass. It had been previously drained as a misdiagnosed pancreatic cyst in another hospital. DIAGNOSIS: A very high amylase level (107140,0 U/l) in drain fluid was noted in laboratory tests. Endoscopic retrograde cholangiopancreatography revealed a biliary cyst located in the distal common bile duct and a pancreaticobiliary anomaly was suggested. A cholangiography per catheter inserted to the biliary cyst showed a large round contrast-filled cyst. A cholangiography following cyst decompression revealed a very long, tortuous bile duct entering the duodenum. INTERVENTIONS: Cholecystectomy, cyst resection, Roux-Y hepaticojejunostomy, and implantation of catheters into pancreatic and bile duct were performed. The postoperative course was uneventful and she was discharged on 12th day without any complications. Histopathology revealed a cyst wall partially lined with biliary-type and mucinous epithelium, with dysplasia ranging from low to high grade (biliary intraepithelial neoplasia, high grade), without invasion. OUTCOMES: The biliary and pancreatic catheters were removed during endoscopic retrograde cholangiopancreatography 8 weeks following surgery without any complications. Fourteen months later, the patient reported good health. LESSONS: Diagnosis of the abdominal cyst should be very precise in order to avoid misdiagnosis and inadequate management. The early diagnosis and proper treatment of BC are needed in order to avoid serious complications. The cholangiocarcinoma is the most dangerous potential complication of BC due to dysplasia within the cyst wall as in our young female patient.
