Increased rate of cholecystectomies performed with doubtful or no indications after laparoscopy introduction: a single center experience

Are LMICs Achieving the Lancet Commission Global Benchmark for Surgical Volumes? A Systematic Review

INTRODUCTION

The Lancet Commission on Global Surgery (LCoGS) set the benchmark of 5000 procedures per 100,000 population annually to meet surgical needs adequately. This systematic review provides an overview of the last ten years of surgical volumes in Low and Middle- Income-Countries (LMICs).

METHODOLOGY

We searched PubMed, Web of Science, Scopus, Cochrane, and EMBASE databases for studies from LMICs addressing surgical volume. The number of surgeries performed per 100,000 population was estimated. We used cesarean sections, hernia, and laparotomies as index cases for the surgical capacities of the country. Their proportions to total surgical volumes were estimated. The association of country-specific surgical volumes and the proportion of index cases with its Gross Domestic Product (GDP) per capita was analyzed.

RESULTS

A total of 26 articles were included in this review. In LMICs, on average, 877 surgeries were performed per 100,000 population. The proportion of cesarean sections was found to be high in all LMICs, with an average of 30.1% of the total surgeries, followed by hernia (16.4%) and laparotomy (5.1%). The overall surgical volumes increased as the GDP per capita increased. The proportions of cesarean section and hernia to total surgical volumes decreased with increased GDP per capita. Significant heterogeneity was found in the methodologies to assess surgical volumes, and inconsistent reporting hindered comparison between countries.

CONCLUSION

Most LMICs have surgical volumes below the LCoGS benchmark of 5000 procedures per 100,000 population, with an average of 877 surgeries. The surgical volume increased while the proportions of hernia and cesarean sections reduced with increased GDP per capita. In the future, it's essential to apply uniform and reproducible data collection methods for obtaining multinational data that can be more accurately compared.

Severidad de la colecistitis aguda en tiempos de COVID-19: ¿mito o realidad?

Introducción. La colecistitis aguda es una de las causas más frecuentes de ingresos hospitalarios y la colecistectomía laparoscópica es el estándar de oro para su manejo. Dentro de los efectos de la pandemia por COVID-19 se ha percibido un aumento en la severidad de presentación en estos pacientes. Este estudio tuvo como objetivo comparar la presentación clínica y quirúrgica de la colecistitis aguda antes y durante la pandemia por COVID-19. Métodos. Estudio retrospectivo de una cohorte con pacientes llevados a colecistectomía laparoscópica por colecistitis aguda entre 2019 y 2020. Se realizó un análisis bivariado y de Kaplan Meier con el tiempo transcurrido entre inicio de síntomas y el ingreso al hospital, y entre el ingreso del hospital y la realización de la cirugía. Resultados. Fueron llevados a colecistectomía laparoscópica por colecistitis aguda un total de 302 pacientes. El tiempo de evolución de los síntomas hasta el ingreso fue de 83,3 horas (IC95%: 70,95 – 96,70) antes de la pandemia y 104,75 horas (IC95%: 87,26 – 122,24) durante la pandemia. El tiempo entre el ingreso al hospital y el procedimiento quirúrgico fue significativamente menor en el período de pandemia (70,93 vs. 42,29; p<0,001). El porcentaje con mayor severidad (Parkland 5) fue igual antes y durante la pandemia (29 %). Conclusión. Se reporta una severidad clínica y quirúrgica similar antes y durante la pandemia por COVID-19, probablemente secundario a los resultados de un tiempo de entrada al quirófano significativamente menor durante la pandemia, debido a una mayor disponibilidad de quirófanos para las patologías quirúrgicas urgentes.

A nationwide analysis of gallbladder surgery in England between 2000 and 2019

BACKGROUND

There are no reports on nationwide trends in subtotal cholecystectomy (STC) and cholecystostomy in England. We hypothesized that, as in the United States, a substantial increase in the utilization of these surgical procedures, over time, may be observed. We aimed to generate a reliable report on 4 of the most common gallbladder surgical procedures in England to allow cross-procedure comparisons and highlight significant changes in the management of benign gallbladder disease over time.

METHODS

We obtained data from NHS Digital and extracted population estimates from the Office of National Statistics. We examined the trends in the use of STC, cholecystostomy, cholecystolithotomy and total cholecystectomy (TC) between 2000 and 2019.

RESULTS

Of the 1,234,319 gallbladder surgeries performed, TC accounted for 96.8% (n = 1,194,786) and the other 3 surgeries for 3.2% (n = 39,533). The total number of gallbladder surgeries performed annually increased by 80.4% from 2000 to 2019. We detected increases in the counts of cholecystostomies by 723.1% (n = 290 in 2000 vs n = 2,387 in 2019) and STCs by 716.6% (n = 217 in 2000 vs n = 1,772 in 2019). Consequently, there was a decrease in the ratio of TC to STC (180:1 in 2000 vs 38:1 in 2019). A similar decrease was observed in the ratio of cholecystectomy to cholecystostomy (135:1 in 2000 vs 29:1 in 2019).

CONCLUSION

Increased utilization of STC and cholecystostomy was detected in England. These findings highlight the importance of regular monitoring of nationwide trends in gallbladder surgery and the associated clinical outcomes.

2020 WSES guidelines for the detection and management of bile duct injury during cholecystectomy

Bile duct injury (BDI) is a dangerous complication of cholecystectomy, with significant postoperative sequelae for the patient in terms of morbidity, mortality, and long-term quality of life. BDIs have an estimated incidence of 0.4-1.5%, but considering the number of cholecystectomies performed worldwide, mostly by laparoscopy, surgeons must be prepared to manage this surgical challenge. Most BDIs are recognized either during the procedure or in the immediate postoperative period. However, some BDIs may be discovered later during the postoperative period, and this may translate to delayed or inappropriate treatments. Providing a specific diagnosis and a precise description of the BDI will expedite the decision-making process and increase the chance of treatment success. Subsequently, the choice and timing of the appropriate reconstructive strategy have a critical role in long-term prognosis. Currently, a wide spectrum of multidisciplinary interventions with different degrees of invasiveness is indicated for BDI management. These World Society of Emergency Surgery (WSES) guidelines have been produced following an exhaustive review of the current literature and an international expert panel discussion with the aim of providing evidence-based recommendations to facilitate and standardize the detection and management of BDIs during cholecystectomy. In particular, the 2020 WSES guidelines cover the following key aspects: (1) strategies to minimize the risk of BDI during cholecystectomy; (2) BDI rates in general surgery units and review of surgical practice; (3) how to classify, stage, and report BDI once detected; (4) how to manage an intraoperatively detected BDI; (5) indications for antibiotic treatment; (6) indications for clinical, biochemical, and imaging investigations for suspected BDI; and (7) how to manage a postoperatively detected BDI.

Diet After Cholecystectomy

Patients with gallstones are often affected by alimentary disorders contributing to the onset of gallstones disease. Cholecystectomy can have nutritional and metabolic consequences in the short-term (diarrhea, abdominal pain and bloating) and in the long-term (increased Body Mass Index with metabolic syndrome, gastritis, liposoluble vitamin deficiency). Pathogenic mechanisms behind these disturbances are reviewed and the need for an early post-operative nutritional intervention based on low-lipid, high-fibers diet, is highlighted.

Nineteen-year trends in incidence and indications for laparoscopic cholecystectomy: the NY State experience

BACKGROUND

Since the introduction of laparoscopic cholecystectomy (LC), there has been continued evolution in technique, instrumentation and postoperative management. With increased experience, LC has migrated to the outpatient setting. We asked whether increased availability and experience has impacted incidence of and indications for LC.

METHODS

The New York (NY) State Planning and Research Cooperative System longitudinal administrative database was utilized to identify patients who underwent cholecystectomy between 1995 and 2013. ICD-9 and CPT procedure codes were extracted corresponding to laparoscopic and open cholecystectomy and the associated primary diagnostic codes. Data were analyzed as relative change in incidence (normalized to 1000 LC patients) for respective diagnoses.

RESULTS

From 1995 to 2013, 711,406 cholecystectomies were performed in NY State: 637,308 (89.58 %) laparoscopic. The overall frequency of cholecystectomy did not increase (1.23 % increase with a commensurate population increase of 6.32 %). Indications for LC during this time were: 72.81 % for calculous cholecystitis (n = 464,032), 4.88 % for biliary colic (n = 31,124), 8.98 % for acalculous cholecystitis (n = 57,205), 3.01 % for gallstone pancreatitis (n = 19,193), and 1.59 % for biliary dyskinesia (n = 10,110). The incidence of calculous cholecystitis declined (-20.09 %, p < 0.0001) between 1995 and 2013; meanwhile, other diagnoses increased in incidence: biliary colic (+54.96 %, p = 0.0013), acalculous cholecystitis (+94.24 %, p < 0.0001), gallstone pancreatitis (+107.48 %, p < 0.0001), and biliary dyskinesia (+331.74 %, p < 0.0001). Outpatient LC incidence catapulted to 48.59 % in 2013, from 0.15 % in 1995, increasing >320-fold. Analysis of LC through 2014 revealed increasing rates of digestive, infectious, respiratory, and renal complications, with overall cholecystectomy complication rates of 9.29 %.

CONCLUSION

A shifting distribution of operative indications and increasing rates of complications should prompt careful consideration prior to surgery for benign biliary disease. For what is a common procedure, LC carries substantial risk of complications, thus requiring the patient to be an active participant and to share in the decision-making process.

Emergency abdominal surgery after solid organ transplantation: a systematic review

AIMS

Due to the increasing number of solid organs transplantations, emergency abdominal surgery in transplanted patients is becoming a relevant challenge for the general surgeon. The aim of this systematic review of the literature is to analyze morbidity and mortality of emergency abdominal surgery performed in transplanted patients for graft-unrelated surgical problems.

METHODS

The literature search was performed on online databases with the time limit 1990-2015. Studies describing all types of emergency abdominal surgery in solid organ transplanted patients were retrieved for evaluation.

RESULTS

Thirty-nine case series published between 1996 and 2015 met the inclusion criteria and were selected for the systematic review. Overall, they included 71671 transplanted patients, of which 1761 (2.5 %) underwent emergency abdominal surgery. The transplanted organs were the heart in 65.8 % of patients, the lung in 22.1 %, the kidney in 9.5 %, and the liver in 2.6 %. The mean patients' age at the time of the emergency abdominal surgery was 49.4 ± 7.4 years, and the median time from transplantation to emergency surgery was 2.4 years (range 0.1-20). Indications for emergency abdominal surgery were: gallbladder diseases (80.3 %), gastrointestinal perforations (9.2 %), complicated diverticulitis (6.2 %), small bowel obstructions (2 %), and appendicitis (2 %). The overall mortality was 5.5 % (range 0-17.5 %). The morbidity rate varied from 13.6 % for gallbladder diseases to 32.7 % for complicated diverticulitis. Most of the time, the immunosuppressive therapy was maintained unmodified postoperatively.

CONCLUSIONS

Emergency abdominal surgery in transplanted patients is not a rare event. Although associated with relevant mortality and morbidity, a prompt and appropriate surgery can lead to satisfactory results if performed taking into account the patient's immunosuppression therapy and hemodynamic stability.

Effect of institutional volume on laparoscopic cholecystectomy outcomes: Systematic review and meta-analysis

AIM: To determine whether institutional laparoscopy cholecystectomy (LC) volume affects rates of mortality, conversion to open surgery, bile leakage and bile duct injury (BDI).

METHODS: Eligible studies were prospective or retrospective cohort studies that provided data on outcomes from consecutive LC procedures in single institutions. Relevant outcomes were mortality, conversion to open surgery, bile leakage and BDI. We performed a Medline search and extracted data. A regression analysis using generalized estimating equations were used to determine the influence of annual institutional LC caseload on outcomes. A sensitivity analysis was performed including only those studies that were published after 1995.

RESULTS: Seventy-three cohorts (127404 LC procedures) were included. Average complication rates were 0.06% for mortality, 3.23% for conversion, 0.44% for bile leakage and 0.28% for bile duct injury. Annual institutional caseload did not influence rates of mortality (P = 0.142), bile leakage (P = 0.111) or bile duct injury (P = 0.198) although increasing caseload was associated with reduced incidence of conversion (P = 0.019). Results from the sensitivity analyses were similar.

CONCLUSION: Institutional volume is a determinant of LC complications. It is unclear whether volume is directly linked to complication rates or whether it is an index for protocolised care.

Cholecystitis

Acute cholecystitis is defined as inflammation of the gallbladder and is usually caused by obstruction of the cystic duct. Cholescintigraphy is the most sensitive imaging modality for cholecystitis. The gold standard treatment of acute cholecystitis is laparoscopic cholecystectomy. Operating early in the disease course decreases overall hospital stay and avoids increased complications, conversion to open procedures, and mortality. Cholecystitis during pregnancy is a challenging problem for surgeons. Operative intervention is generally safe for both mother and fetus, given the improved morbidity of the laparoscopic approach compared with open, although increased caution should be exercised in women with gallstone pancreatitis.
