RÉSUMÉ
The prevalence of gastrointestinal (GI) cancer is increasing across diverse regions of India, demanding further investigation at the state level. In response, a new department of surgical gastroenterology was started at a tertiary-care hospital in Pune, Western Maharashtra, in 2019. The objective of this study was to explore the pattern of admissions in terms of demographics and types of GI cancers over the last four years (i.e., 2020-2023). Retrospective admissions data were collected from hospital records for 2020-2023. A total of 2294 patients were treated at the outpatient department (OPD), and 135 patients were admitted to the inpatient department (IPD). The data comprised OPD/IPD admissions, age, gender, diagnosis, and length of stay (LoS). In addition to basic statistical reporting, t-tests were used to explore differences among the study variables. Out of 135 GI cancer patients, 57% were male. The mean age of inpatients per year ranged from 53 to 60 years, with an average age of 56.35 ± 10.14 years. The average LoS was 12.31 ± 9.39 days. From 2020 to 2023, the number of admissions increased from 5 to 57. The increase was more pronounced in men than women (57% vs. 43%, respectively). Furthermore, increased admission of younger patients was observed, and the average LoS decreased from 17 to 11 days from 2020 to 2023, respectively. A statistically significant difference in LoS (p = 0.023) was observed based on gender, where LoS was longer for women than for men on average (13.5 ± 10.8 vs. 9.46 ± 8.28, respectively). As GI cancer incidence is predicted to continue to increase in India, these new estimates will help to plan cancer prevention and control through intervention via early detection and management.
RÉSUMÉ
The present study is primarily focused on the coupled effects of substrate heating, colloidal dispersion, and particle size variation on the contact line (CL) pinning-depinning dynamics of evaporating droplets containing mono- (3/4.5 µm) and bidispersed (3 and 4.5 µm) polystyrene colloidal particles on poly(dimethylsiloxane) (PDMS) substrates. Experimental techniques such as high-speed visualization, optical microscopy, infrared thermography, and scanning electron microscopy are implemented to discover the plausible causes dictating the underlying physics. In the case of the nonheated substrate, there exists a significant delay in the CL depinning for the evaporating droplets containing bidispersed particles, as opposed to the monodispersed cases. A first-order model is illustrated for the determination of the net horizontal force acting on the particles near the CL. Interestingly, the model's findings revealed that due to the difference of particle size in the case of the bidispersed suspension, the interparticle contact force gets modified, thus enhancing the CL pinning. For the heated substrate cases, droplets with monodispersed particles (3 µm) exhibit a substantial delay in the CL depinning, whereas a nearly complete pinning of the CL is witnessed for the case of bidispersed colloidal suspension droplets. It is mainly due to the augmentation of particle deposition near the CL because of the circulatory thermal Marangoni and outward capillary flows. Thus, the mobility of the CL is inhibited, which is further reinforced by the presence of different-sized particles. Eventually, a ring-like deposition is observed, as opposed to an inner deposit commonly observed from the evaporation of colloidal droplets on hydrophobic substrates.

BACKGROUND: Frey's operation is indicated on patients with chronic pancreatitis who have "head dominant" disease and involves resection of the head of pancreas and lateral pancreaticojejunostomy (LRLPJ). There is little information about the postoperative complications after this procedure and the factors likely to be responsible for them. This paper addresses this aspect of LRLPJ. METHODS: A retrospective review was made of records of 41 patients undergoing LRLPJ for chronic pancreatitis between January 1990 to June 2003. RESULTS: Sixteen (39%) patients had 19 complications in the early postoperative period; septic complications were the commonest. One patient died. Regression analysis showed preoperative endoscopic pancreatic stenting to be the factor responsible for majority of these complications (P = 0.0041). Patients with a history of pancreatic stenting had a prolonged hospital stay (P = 0.022). CONCLUSIONS: Postoperative complications after LRLPJ are usually septic in nature and are likely to occur more often in patients in whom endoscopic pancreatic stenting has been performed before surgical intervention.
