Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide. A multimethods analysis was performed as part of the GlobalSurg 3 study—a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital. Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3·85 [95% CI 2·58–5·75]; p<0·0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63·0% vs 82·7%; OR 0·35 [0·23–0·53]; p<0·0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer. Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised.

Colitis cystica profunda is a rare nonneoplastic disease defined by the presence of intramural cysts that contain mucus, usually situated in the rectosigmoid area, which can mimic various malignant lesions and polyps. Its etiology still remains not fully elucidated, and several mechanisms such as congenital, post-traumatic, and infectious have been implicated in the development of this rare entity. Herein, we describe a unique case of colitis cystica profunda in the setting of Peutz-Jeghers-type polyp of the sigmoid colon, associated with high-grade dysplasia of the overlying epithelium in a 48-year-old female patient, who presented to the emergency room with signs of intestinal obstruction. To the best of our insight, this is the first manifestation ever reported in the literature regarding the coexistence of solitary Peutz-Jeghers-type polyp, colitis cystica profunda, and high-grade dysplasia of the epithelium of the colon. The purpose of this case report is to highlight colitis cystica profunda and its clinical significance. An uncommon nonneoplastic entity, many times masquerading as malignant lesion of the rectosigmoid area of the colon. Clinicians and pathologists should be aware of this benign condition that is found incidentally postoperatively in patients undergoing colectomies, leading to unnecessary increase of morbidity and mortality in these patients, who otherwise could have been cured with conservative treatment only.
Laparoscopic total gastrectomy is on the rise. One of the most technically demanding steps of the approach is the construction of esophago-jejunal anastomosis. Several laparoscopic anastomotic techniques have been described, like linear stapler side-to-side or circular stapler end-to-side anastomosis; limited data exist regarding hand-sewn esophago-jejunal anastomosis. The study took place between January 2018 and June 2021. Patients enrolled in this study were adults with proximal gastric or esophago-gastric junction Siewert type III tumors that underwent 3D-assisted laparoscopic total gastrectomy. A hand-sewn esophago-jejunal anastomosis was performed in all cases laparoscopically. Forty consecutive cases were performed during the study period. Median anastomotic suturing time was 55 min, with intra-operative methylene blue leak test being negative in all cases. Median operating time was 240 min, and there were no conversions to open. The anastomotic leak rate and postoperative stricture rate were zero. The 30- and 90-day mortality rates were zero. Laparoscopic manual esophago-jejunal anastomosis utilizing a 3D platform in total gastrectomy for cancer can be performed with excellent outcomes regarding anastomotic leak and stricture rate. This anastomotic approach, although technically challenging, is safe and reproducible, with prominent results that can be disseminated in the surgical community.
Background: The incidence of single-nucleotide-polymorphisms with malignant potential in esophageal cancer tissues has only been sparsely investigated in the west. Hence, we explored the contribution of four long non-coding RNAs’ polymorphisms HOTAIR rs920778, LINC00951 rs11752942, POLR2E rs3787016 and HULC rs7763881 in esophageal cancer susceptibility. Methods and results: Formalin-fixed paraffin-embedded tissue specimens from 95 consecutive patients operated for esophageal/esophagogastric junction carcinoma during 25/03/2014-25/09/2018 were processed. Demographic data, histopathological parameters, surgical and oncological outcomes were collected. DNA findings of the abovementioned population were compared with 121 healthy community controls. Both populations were of European/Greek ancestry. Sixty-seven patients underwent Ivor Lewis/McKeown esophagectomy for either squamous cell esophageal carcinoma (N = 6) or esophageal/esophagogastric junction Siewert I or II adenocarcinoma (N = 61). Twenty-eight patients were subjected to extended total gastrectomy for esophagogastric junction Siewert III adenocarcinoma. Neither LINC00951 rs11752942 nor HULC rs7763881 polymorphisms were detected more frequently in esophageal cancer patients compared with healthy community subjects. A significantly higher presence of HOTAIR rs920778 TT genotype in esophagogastric junction Siewert I/II adenocarcinoma was identified. POLR2E rs3787016 C allele and CC genotypes were overrepresented in the control group, and when found in esophageal cancer carriers were associated with earlier disease stages, as well as with minor lymph node involvement and lesser metastatic potential. Conclusions: HOTAIR rs920778 may serve as a potential therapeutic suppression target, while POLR2E rs3787016 may represent a valuable biomarker to evaluate esophageal cancer predisposition and predict treatment response and prognosis. Clinical implications of these findings need to be verified with further prospective studies with larger sample-size.
Long non-coding RNAs’ HOTAIR rs920778, LINC00951 rs11752942, POLR2E rs3787016, and HULC rs7763881 are progressively reported having a close genetic affinity with esophageal carcinogenesis in the East. Nonetheless, their correlation with variables already endorsed as significant prognostic factors in terms of staging, guiding treatment and predicting recurrence, metastasis, and survival have yet to be explored. Herein, we investigated their prognostic value by correlating them with clinicopathological and laboratory prognostic markers in esophageal cancer in the West. Formalin-fixed paraffin-embedded tissue specimens from 95 consecutive patients operated on for esophageal cancer between 2014 and 2018 were compared with 121 healthy community controls. HULC was not detected differently in any of the cancer prognostic subgroups. LINC00951 was underrepresented in Ca19.9 elevated subgroup. HOTAIR was more frequent in both worse differentiation grade and positive Signet-Ring-Cell and Ca19.9 subgroups. POLR2E was identified less frequently in Adenocarcinoma, Signet-Ring-Cell, and Diffuse histologies, as well as in Perineural, Lymphovascular, and Perivascular Invasion positive, while it was overrepresented in CEA positive subgroup. These lncRNAs polymorphisms may hold great potential not only as future therapeutic agents but also as novel markers for predictive analysis of esophageal cancer risk, clinical outcome, and survival. Clinical implications of these findings need to be validated with prospective larger sample-size studies.

Background: Epiphrenic oesophageal diverticula are rare and often asymptomatic. When symptoms are present, minimally invasive diverticulectomy is considered the gold standard of treatment. While there is an agreement on the pre-operative assessment, no consensus is achieved when it comes to surgical technique. In the present study, we report our experience and propose a standardised approach to manage this rare oesophageal disorder. Materials and Methods: We prospectively analysed data of all consecutive patients who underwent three-dimensional (3D) laparoscopic distal oesophageal diverticulum resection during 2015–2020 at Upper gastrointestinal surgical department, St Thomas’ Hospital, regarding pre-operative assessment, surgical technique, peri-and post-operative outcomes. Results: Six patients were submitted to 3D laparoscopic diverticulectomy, five of which with additional anterior myotomy and fundoplication and one with additional hiatal hernia repair only. Three patients followed a specific diet in preparation for surgery. Median pre-operative Eckardt symptom score was five. Two patients had normal manometry. Median operative time was 180 min, median estimated blood loss was <100 ml, neither intraoperative complications nor conversions to open approach occurred. All patients reported a complete resolution of symptoms directly after surgery. Median follow-up was 66 months. Five patients have none or minimal residual symptoms. One had recurrence requiring a revision operation for intermittent dysphagia. Conclusions: 3D laparoscopic diverticulectomy offers a reasonable chance of treatment in patients with epiphrenic diverticula. Optimal selection of patients, optimisation for surgery, gaining the surgical experience of carrying out these techniques and impact on short- and long-term results are issues that still remain under debate.
