Aberrant pancreas adenocarcinoma in the stomach: A case report and literature review.

RATIONALE: Aberrant pancreatic tissue in the gastrointestinal tract is a relatively common finding. However, malignant transformation is extremely rare. Herein, we report a case of ectopic pancreatic ductal adenocarcinoma in the stomach wall. PATIENT CONCERNS: A 38 year old male presented with nausea, bloating, abdominal distention and weight loss for 4 months. DIAGNOSES: Endoscopy of upper gastrointestinal tract was performed twice with 2 months interval and a stenotic pyloric part was observed with a suspected submucosal lesion. It was sampled both times, however the pathology findings of the mucosal biopsies were unremarkable with no identifiable neoplastic structures. CT scan and MRI was performed and showed a thickened pyloric wall with a submucosal lesion 15 × 15 mm in diameter. Blood levels of tumor markers carcinoembrionic antigen and carbohydrate antigen 19-9 were within a normal range. INTERVENTIONS: Pyloric stenosis progressed and the patient underwent a Billroth type I distal gastric resection with D2 lymphadenectomy. Pathologic examination revealed a well differentiated ductal adenocarcinoma arising in the heterotopic pancreatic tissue (Heinrich type III). The resection margins and lymph nodes were free of tumor. The patient received adjuvant chemotherapy with 6 courses of XELOX. OUTCOMES: No disease recurrence is reported in 12 months follow-up. LESSONS: Aberrant pancreatic ductal adenocarcinoma in the stomach is a rare finding, however this pathology should be included in the differential diagnosis of gastric submucosal lesion causing pyloric stenosis.

Suspected and Confirmed Acute Appendicitis During the COVID-19 Pandemic: First and Second Quarantines-a Prospective Study.

Purpose: COVID-19 posed an unprecedented modern global healthcare crisis affecting both elective and urgent surgeries. The aim of this study is to evaluate the difference in the presentation of acute appendicitis (AA) before and during the COVID-19 era, the first and second quarantines. Methods: We performed a prospective study from December 2018 to May 2021. Two cohorts were analysed, one with patients who presented to the emergency department (ED) with suspected AA and the second with confirmed AA. Both cohorts were divided into four groups: before COVID-19, during the first quarantine, between the first and second quarantine, and during the second quarantine. Data such as demographics, the time to first contact with the healthcare provider and time to operation, laboratory tests, clinical stage of AA, length of stay, and COVID-19 status were collected. A total of 469 patients were enrolled. Results: A total of 209 patients were male (45%) and 260 were female (55%), with the median age being 33 years (24-45). In the first cohort of suspected AA, there was no difference in sex; however, more older patients presented to the ED during the first quarantine (41 years) compared with other groups (28.5, 36, and 32.5 years), p < 0.000. Before the pandemic, there was a shorter duration of symptoms to first contact with the healthcare provider (13 h) compared with other groups, p = 0.001. In the second cohort of confirmed AA, there was a shorter period of time to operation from first symptoms before the pandemic (22 h) compared with other groups (30, 35, 30.5 h), p < 0.000. There were more complicated gangrenous, perforated appendicitis or periappendicular abscess in Group 2 and 3 (26, 22 and 10%, and 26, 22 and 2%, respectively) compared with Group 1 (20, 4 and 3%) and Group 4 (22, 12, and 2%), p = 0.009. Hospital stay was longer during the first quarantine (3 days) compared with other groups (2 days), p = 0.009. Six patients were COVID-19 positive: one from Group 3 and five from Group 4 (p > 0.05). Conclusions: Our study suggests that during the first quarantine of the COVID-19 pandemic, there was delayed presentation to the ED with suspected AA and there was a greater proportion of complicated appendicitis and longer hospitalization in confirmed cases as well.

Short-term clinical and functional results of rectal wall suture defect after transanal endoscopic microsurgery-a prospective cohort study.

PURPOSE: Our goal was to assess the outcomes of rectal wall suture during the early and late periods after transanal endoscopic microsurgery (TEM) and long-term bowel function. METHODS: Patients who underwent TEM for rectal neoplasms from May 2017 to March 2021 were prospectively included. A total of 70 patients were enrolled. Seven to 10 days after TEM, clinical data were recorded, and digital rectal examination and rigid proctoscopy were performed. After at least 6 months, bowel function was evaluated using low anterior resection syndrome (LARS) and Wexner questionnaires. RESULTS: Forty-five men with an average age of 67 ± 10.1 (40-85) were included. TEM sutures were recorded as intact in 48/70 (68%) and as dehiscent in 22/70 (32%). It did not have any significant clinical manifestation and was not related with longer postoperative stay or incidence of postoperative complications. Eight of 22 (36.4%) patients with suture dehiscence had per rectal bleeding or febrile temperature without any need for intervention or treatment. The only risk factor for wound dehiscence was a posteriorly located defect. In late postoperative period, there was no difference between groups in LARS or Wexner questionnaire (p value 0.72 and 0.85, respectively). CONCLUSIONS: Our study suggests that 1/3 of the patients' rectal wall defect after TEM will undergo dehiscence in early postoperative period and will not transfer to clinically significant manifestation (without a need of hospitalization or prolonging it). In late postoperative period, there is no difference in bowel function.

Local Excision ± Chemoradiotherapy vs. Total Mesorectal Excision for Early Rectal Cancer: Case-Matched Analysis of Long-Term Results.

Background: Our aim was to compare the bowel function and oncologic outcomes following these two treatment modalities. Materials and methods: This was a single-center study with 67 patients included between 2009 and 2018. A total of 32 patients underwent total mesorectal excision (TME) group and 35 transanal local excisions (LE) ± chemoradiation. We performed a case-matched analysis: we matched the patients by age, cancer stage, and comorbidities. Duration of operation, postoperative complications, length of hospital stay, and long-term functional and oncological outcomes were compared. We calculated oncological outcomes using Kaplan-Meier Cox diagrams. In addition, we used a low anterior resection syndrome (LARS) score for the bowel function assessment. Results: Mean operation time in the LE group was 58.8 ± 45 min compared with the TME group that was 121.1 ± 42 min (p = 0.032). Complications were seen in 5.7% in LE group and 15.62% in TME group (p = 0.043). ~85.2% of the patients had no LARS in LE group compared with 54.5% in TME group (p = 0.018). Minor LARS was 7.4% in LE group compared with 31.8% in TME group (p = 0.018); major LARS was 7.4 and 13.7%, respectively (p = 0.474). Hospital stay was 2.77 days in LE group compared with 9.21 days in TME group (p = 0.036). The overall survival was 68.78 months in LE group compared with 74.81 months in TME group (p = 0.964). Conclusion: Our results of a small sample size showed that local excision ± chemoradiation is a rather safe method for early rectal cancer compared with gold standard treatment. In addition, better bowel function is preserved with less postoperative complications and shorter hospital stays.

Quality of Life and Bowel Function Following Early Closure of a Temporary Ileostomy in Patients with Rectal Cancer: A Report from a Single-Center Randomized Controlled Trial.

The aim of this study was to assess quality of life and bowel function in patients undergoing early vs. standard ileostomy closure. We retrospectively assessed patients from our previous randomized controlled trial. Patients with a temporary ileostomy who underwent rectal cancer surgery and did not have anastomotic leakage or other. Early closure (EC; 30 days after creation) and standard closure (SC; 90 days after creation) of ileostomy were compared. Thirty-six months (17-97) after stoma closure, we contacted patients by phone and filled in two questionnaires-The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) and low anterior resection syndrome (LARS) score. This index trial was not powered to assess the difference in bowel function between the two groups. All the patients in the SC group had anastomosis <6 cm from the anal verge compared to 42 of 43 (97.7%) in the EC group. There were no statistically significant differences between EC (26 patients) and SC (25 patients) groups in the EORTC QLQ-C30 and LARS questionnaires. Global quality of life was 37.2 (0-91.7; ±24.9) in the EC group vs. 34.3 (0-100; ±16.2) in the SC (p = 0.630). Low anterior resection syndrome was present in 46% of patients in the EC and 56% in the SC group (p = 0.858). Major LARS was found more often in younger patients. However, no statistical significance was found (p = 0.364). The same was found with quality of life (p = 0.219). Age, gender, ileostomy closure timing, neoadjuvant treatment, complications had no effect of worse bowel function or quality of life. There was no difference in quality of life or bowel function in the late postoperative period after the early vs. late closure of ileostomy based on two questionnaires and small sample size. None of our assessed risk factors had a negative effect on bowel function o quality of life.

Traumatic spleen rupture diagnosed during postmortem dissection: A STROBE-compliant retrospective study.

Spleen is typically injured in blunt abdominal trauma. Spleen injuries make 42% of all blunt abdominal injuries. The aim of this study was to perform a retrospective assessment of the cases of acute and subacute isolated traumatic spleen ruptures.A retrospective study performed on 50 patients, whose cause of death was isolated spleen rupture and bleeding into the abdominal cavity.An acute spleen rupture was diagnosed in 47 cases, whereas the rest 3 cases demonstrated a subacute rupture. In cases of acute spleen rupture, the mean weight of spleen was 309.6 g, whereas in 3 cases of subacute rupture the mean weight of the organ achieved 710 g. The mean weight of spleen in the control group with no spleen rupture was 144.7 g.Recording of the cases of isolated acute and subacute traumatic spleen ruptures and morphological assessment of them are important in forensic pathology science and in clinical practice as well.
