“…4,[11][12][13][14] Surgical time in dogs, however, was found to be longer in minimally invasive splenectomy when compared to OS. 4,13,14 Similar postoperative findings have been noted in cats undergoing minimally invasive procedures [15][16][17] ; however, currently only a limited number of reports exist. While multiple reports have previously described minimally invasive splenectomy in dogs, 4,8,13,14 only a single case series 17 previously described operative technique and outcome of TLS and laparoscopic-assisted splenectomy (LAS) in 3 cats.…”

OBJECTIVE To report the perioperative outcome and complications in cats undergoing minimally invasive splenectomy. ANIMALS 17 client-owned cats. METHODS Perioperative data were collected from cats undergoing minimally invasive splenectomy from September 2010 to June 2023. Data included history, signalment, preoperative examination and diagnostic testing results, operative technique and time, perioperative outcomes, complications, hospitalization duration, histopathological diagnosis, and outcome. RESULTS 13 spayed females and 4 neutered males were included, with a median age of 144 months (48 to 196 months). Seven cats underwent total laparoscopic splenectomy (TLS), with 1 cat requiring conversion from TLS to laparoscopic-assisted splenectomy (LAS) due to splenomegaly and an additional cat requiring conversion from TLS to open splenectomy due to uncontrollable splenic capsular hemorrhage. Ten cats underwent LAS, with 1 cat requiring conversion to open splenectomy due to splenomegaly. Additional procedures were performed in 13 cats, with the most common being liver biopsy in 10 cats. Median operative times were 50 minutes (45 to 90 minutes) for TLS and 35 minutes (25 to 80 minutes) for LAS. An intraoperative complication occurred in 1 cat. All but 1 cat survived to discharge. Median follow-up time was 234 days (18 to 1,761 days), with 15 of 16 cats confirmed alive at 30 days and 9 of 16 cats alive at 180 days postoperatively. CLINICAL RELEVANCE Minimally invasive splenectomy in this cohort of cats was associated with short operative times and a low perioperative complication rate. Veterinary surgeons may consider minimally invasive splenectomy as an efficient and feasible technique in the treatment of splenomegaly or modestly sized splenic masses for diagnostic and therapeutic purposes in cats.

“…O felino do presente relato deu entrada para atendimento com a idade de aproximadamente 7 meses, entretanto, em literatura, a maioria dos gatos apresentam sinais clínicos por volta dos 6 meses de idade quando se trata do DPSC (IZZO et al, 2022). Uma grande proporção de gatos pode apresentar uma estatura pequena ou atrofiada com um escore corporal baixo (LIPSCOMB et al, 2009), o que foi possível ser visto no caso relatado, já que o irmão de mesma ninhada apresentava o desenvolvimento normal comparado a paciente.…”

“…7 As laparoscopic techniques are applied to a wider range of procedures, there has been increasing interest in minimally invasive portosystemic shunt attenuation, which has been recently reported in dogs 12,13 and cats. 14 The pressure of the portal vasculature is important for surgical decision-making in cases of portosystemic shunt attenuation. One of the primary complications associated with acute attenuation of a portosystemic shunt is portal hypertension, which can result in ascites, gastrointestinal ulceration, systemic hypotension, and abdominal pain.…”

ObjectiveThe adverse effects of intra‐abdominal pressure from capnoperitoneum on cardiovascular and pulmonary systems have been well documented, but the effects on portal pressures in dogs with various insufflation pressures is poorly defined. The aim of the present study was to measure the effect of a range of insufflation pressures on the portal pressure, using direct pressure measurements in patients undergoing laparoscopy.Study designClinical randomized prospective study.AnimalsNine client‐owned dogs undergoing routine laparoscopy.MethodsTwo rounds of direct portal pressure assessments were performed, at insufflation pressures of 0, 6, 10, and 14 mmHg in a predetermined randomized sequence. The data were analyzed for effects of insufflation pressure, hemodynamic alterations, and round. A best‐fit exponential model of the relationship between portal pressure and insufflation pressure was created.ResultsPortal pressure increased by 38% at 6 mmHg, 95% at 10 mmHg, and 175% at 14 mmHg compared to baseline. Portal pressure increased at an average rate of 7.45% per mmHg of insufflation pressure. Effects of weight, weight/insufflation pressure interaction, and round of insufflation were not statistically significant. No systemic hemodynamic adverse events were observed.ConclusionPortal pressure increased as insufflation pressure increased. There was no clinically significant difference in baseline portal pressure between rounds of insufflation.Clinical significanceThis exponential model of portal pressure supports the use of the minimum insufflation pressure to allow visualization during laparoscopy. The return of portal pressure to baseline following desufflation supports the comparison of portal pressure measurements before and after laparoscopic shunt attenuation.
