Background: The incidence of the highly morbid and potentially lethal gangrenous cholecystitis was reportedly increased during the COVID-19 pandemic. The aim of the ChoCO-W study was to compare the clinical findings and outcomes of acute cholecystitis in patients who had COVID-19 disease with those who did not. Methods: Data were prospectively collected over 6 months (October 1, 2020, to April 30, 2021) with 1-month follow-up. In October 2020, Delta variant of SARS CoV-2 was isolated for the first time. Demographic and clinical data were analyzed and reported according to the STROBE guidelines. Baseline characteristics and clinical outcomes of patients who had COVID-19 were compared with those who did not. Results: A total of 2893 patients, from 42 countries, 218 centers, involved, with a median age of 61.3 (SD: 17.39) years were prospectively enrolled in this study; 1481 (51%) patients were males. One hundred and eighty (6.9%) patients were COVID-19 positive, while 2412 (93.1%) were negative. Concomitant preexisting diseases including cardiovascular diseases (p < 0.0001), diabetes (p < 0.0001), and severe chronic obstructive airway disease (p = 0.005) were significantly more frequent in the COVID-19 group. Markers of sepsis severity including ARDS (p < 0.0001), PIPAS score (p < 0.0001), WSES sepsis score (p < 0.0001), qSOFA (p < 0.0001), and Tokyo classification of severity of acute cholecystitis (p < 0.0001) were significantly higher in the COVID-19 group. The COVID-19 group had significantly higher postoperative complications (32.2% compared with 11.7%, p < 0.0001), longer mean hospital stay (13.21 compared with 6.51 days, p < 0.0001), and mortality rate (13.4% compared with 1.7%, p < 0.0001). The incidence of gangrenous cholecystitis was doubled in the COVID-19 group (40.7% compared with 22.3%). The mean wall thickness of the gallbladder was significantly higher in the COVID-19 group [6.32 (SD: 2.44) mm compared with 5.4 (SD: 3.45) mm; p < 0.0001]. Conclusions: The incidence of gangrenous cholecystitis is higher in COVID patients compared with non-COVID patients admitted to the emergency department with acute cholecystitis. Gangrenous cholecystitis in COVID patients is associated with high-grade Clavien-Dindo postoperative complications, longer hospital stay and higher mortality rate. The open cholecystectomy rate is higher in COVID compared with non -COVID patients. It is recommended to delay the surgical treatment in COVID patients, when it is possible, to decrease morbidity and mortality rates. COVID-19 infection and gangrenous cholecystistis are not absolute contraindications to perform laparoscopic cholecystectomy, in a case by case evaluation, in expert hands. Graphical

Background: Literature suggests colonic resection and primary anastomosis (RPA) instead of Hartmann’s procedure (HP) for the treatment of left-sided colonic emergencies. We aim to evaluate the surgical options globally used to treat patients with acute left-sided colonic emergencies and the factors that leading to the choice of treatment, comparing HP and RPA. Methods: This is a prospective, international, multicenter, observational study registered on ClinicalTrials.gov. A total 1215 patients with left-sided colonic emergencies who required surgery were included from 204 centers during the period of March 1, 2020, to May 31, 2020. with a 1-year follow-up. Results: 564 patients (43.1%) were females. The mean age was 65.9 ± 15.6 years. HP was performed in 697 (57.3%) patients and RPA in 384 (31.6%) cases. Complicated acute diverticulitis was the most common cause of left-sided colonic emergencies (40.2%), followed by colorectal malignancy (36.6%). Severe complications (Clavien-Dindo ≥ 3b) were higher in the HP group (P < 0.001). 30-day mortality was higher in HP patients (13.7%), especially in case of bowel perforation and diffused peritonitis. 1-year follow-up showed no differences on ostomy reversal rate between HP and RPA. (P = 0.127). A backward likelihood logistic regression model showed that RPA was preferred in younger patients, having low ASA score (≤ 3), in case of large bowel obstruction, absence of colonic ischemia, longer time from admission to surgery, operating early at the day working hours, by a surgeon who performed more than 50 colorectal resections. Conclusions: After 100 years since the first Hartmann’s procedure, HP remains the most common treatment for left-sided colorectal emergencies. Treatment’s choice depends on patient characteristics, the time of surgery and the experience of the surgeon. RPA should be considered as the gold standard for surgery, with HP being an exception.

This report reviews our experience with 104 transabdominal preperitoneal (TAPP) hernia repairs, using a selective staple-free technique, over the period April 2003 to July 2007 (50 months). Ninety-one patients underwent TAPP repair (13 bilateral). Eighty-one were males and 10 females. Mean age was 61 years. There have been 58 right inguinal hernias and 46 left. We had 47 indirect, 42 direct, 6 pantaloon, 4 supravesicular, 3 inguinal-scrotal, 2 sliding, and 1 femoral hernia. Twenty-three of the hernias we repaired were recurrences. We used a modified staple-free technique with the placement of a 15 x 10 cm polypropylene mesh in the preperitoneal space with sutured peritoneal closure. The mesh was stapled selectively only in very large defects (nine repairs; 9%). We used nondisposable instruments and trocars. We had no conversions. Mean operative time was 47 min/repair with a mean hospitalization of 1.2 nights. We had 1 recurrence (mean follow-up, 34 months). Postoperative complications were: preperitoneal hematoma 1, urinary retention 1, and inguinal seromas/hematomas 11. Mean return to normal activities was 7 days. TAPP repair is a technically demanding laparoscopic technique, but once mastered, is safe and effective with a high degree of patient satisfaction. Stapling the mesh is not necessary in most cases, thus resulting in a remarkably low cost. The rapid rehabilitation typically associated with laparoscopic surgery was seen in all our patients. The low recurrence rate (1% in our series) compares favorably to other tension-free techniques.

Background/Objectives: Complete mesocolic excision (CME) has recently been proposed as a radical operation for the treatment of colon cancer. Increasing evidence suggests a survival benefit from this operation, although the exact reasons for this remain largely unknown. Methods: We have undertaken a comprehensive review of the literature in PubMed and Embase databases, examining the potential mechanisms explaining this oncologic benefit. Results: Complete mesocolic excision with central vascular ligation appears to improve the rates of radial margin negativity and is associated with increased lymph node yield and improved staging for colon cancer patients by removal of apical lymph nodes and removal of skip metastasis. The en bloc removal of the cancer-related mesentery along the interfascial plane between the mesocolon and retroperitoneal structures removes en bloc tumor deposits that appear to have a significant negative effect on cancer prognosis, irrespective of lymph node status. CME is associated with decreased rates of local recurrence and improved disease-free and overall survival. The existing literature suffers from a lack of data on molecular pathology and integration of prognostic pathologic factors such as tumor deposits in patients undergoing complete mesocolic excision. Conclusions: CME confers significant benefits in terms of local control of the disease and improves cancer-specific survival. Further research on the matter is necessary to incorporate prognostic pathologic and molecular parameters.
